Definitive Merger Proxy

After careful consideration, the board of directors of Endwave Corporation, or Endwave, has unanimously adopted and approved an Agreement and Plan of Merger in which a wholly-owned subsidiary of GigOptix, Inc., or GigOptix, will merge with and into Endwave, leaving Endwave as a wholly-owned subsidiary of GigOptix. Endwave is sending you the accompanying proxy statement/prospectus to notify you of the special meeting of Endwave stockholders being held to vote on the adoption of the merger agreement and to ask you to vote at the special meeting in favor of the adoption of the merger agreement, as well as a proposal to enable Endwave to adjourn and postpone the special meeting. The special meeting will be held at 8:00 a.m. (local time) on June 17, 2011, at Endwave’s offices at 130 Baytech Drive, San Jose, CA 95134.

GigOptix’ common stock trades on the OTC Bulletin Board under the symbol “GGOX.OB” and Endwave’s common stock trades on the Nasdaq Global Market under the symbol “ENWV.”

If the merger is completed, GigOptix will issue shares of its common stock to holders of Endwave common stock, restricted stock units and options to purchase Endwave common stock with an exercise price less than the closing price as reported on the Nasdaq Global Market on the trading day immediately prior to the effective time of the merger, which we refer to as in-the-money options. The total number of shares GigOptix will issue to holders of outstanding Endwave in-the-money options is determined by a formula that is based on the closing price of Endwave and GigOptix common stock on the trading day immediately preceding the date the merger is completed. The intent of this formula is to give the holders of Endwave options GigOptix shares with a market value approximately equal to the “spread value” of such options. “Spread value” is the product of the total number of shares subject to the option and the difference between the closing price of Endwave’s common stock on the Nasdaq Global Market on the trading day prior to the effective time of the merger and the option’s per share exercise price. Holders of Endwave stock options that are not in-the-money will not be entitled to receive any shares of GigOptix common stock for those stock options. We believe that treating options in this manner compensates the optionholders for the current realizable value of their options but prevents any future dilution to the holders of Endwave and GigOptix stock that would result if such options were assumed by GigOptix.

The number of GigOptix shares to be issued to holders of Endwave common stock and Endwave restricted stock units is determined according to a separate formula set forth in the merger agreement. The intent of this formula is for GigOptix to issue a total number of shares in exchange for Endwave common stock and Endwave restricted stock units equal to 42.5% of the outstanding stock of the combined company, minus 42.5% of the number derived from the formula used in calculating the number of shares of GigOptix common stock to be issued to holders of outstanding Endwave in-the-money options. The specific number of shares of GigOptix common stock to be issued in the merger, as well as the conversion ratio for Endwave shares and the value of the shares GigOptix will issue, cannot be determined until the time the merger is completed because the number of shares of GigOptix common stock and Endwave common stock, restricted stock units and in-the-money options outstanding at the time the merger is completed, and the closing prices of both Endwave’s and GigOptix’ common stock on the trading day immediately prior to the date the merger is completed, cannot be determined until such time. If the merger were completed on April 28, 2011, based on the GigOptix and Endwave common stock and Endwave options and restricted stock units outstanding as of such date and the respective closing prices of GigOptix’ and Endwave’s common stock on April 27, 2011, each outstanding share of Endwave common stock would convert into approximately 0.909 shares of GigOptix common stock, 9,115,007 shares of GigOptix common stock would be issued to the holders of Endwave common stock and restricted stock units, and 74,573 shares of GigOptix common stock would be issued to the holders of Endwave in-the-money options, for a total of 9,189,580 shares of GigOptix common stock issued in the merger.

The merger cannot be completed unless Endwave stockholders vote to adopt the merger agreement. Your vote is very important, regardless of the number of shares of common stock you own, and Endwave urges you to take the time to vote by following the instructions on your proxy card regardless of whether you plan to attend the special meeting in person.

Important Notice Regarding the Availability of Proxy Materials for Endwave’s Special Meeting of Stockholders to Be Held on June 17, 2011: The accompanying proxy statement/prospectus is available at https://materials.proxyvote.com/29264A.

The closing prices of GigOptix and Endwave common stock as of the trading day prior to completion of the merger, as well as the number of shares of GigOptix and Endwave common stock and the number of Endwave restricted stock units and options outstanding as of the completion of the merger are necessary to determine the conversion ratio and aggregate number of shares of GigOptix common stock being issued. Because the market prices of GigOptix and Endwave common stock and numbers of outstanding shares of common stock of both companies and Endwave restricted stock units and options will continue to fluctuate until the completion of the merger, the conversion ratio and the aggregate number of shares of GigOptix common stock to be issued in the merger, as well as the value of such shares, cannot be determined until immediately before the consummation of the merger, and therefore will not be known to Endwave stockholders at the time of the stockholder vote on the merger proposal at the special meeting. On April 28, 2011, there were 12,374,947 shares of GigOptix common stock outstanding, 10,022,590 shares of Endwave common stock outstanding (including shares to be issued upon settlement of restricted stock units) and 398,425 Endwave options that were “in-the-money” (options that had an exercise price below the closing price of Endwave’s common stock on the Nasdaq Global Market on April 27, 2011). On April 27, 2011, the closing price of GigOptix’ common stock was $2.60 and the closing price of Endwave’s common stock was $2.40. As a result, if the merger were completed on April 28, 2011, GigOptix would issue 74,573 shares of

common stock to the holders of Endwave options. 42.5% of that amount is 31,693. The aggregate number of shares GigOptix common stock that would be issued to the holders of Endwave common stock (including shares issued upon settlement of restricted stock units and assuming no shares are subject to perfected appraisal rights or are held by Endwave, Merger Sub, GigOptix or any subsidiary of GigOptix) if the merger closed on April 28, 2011 would be 9,146,700 ((0.425/0.575) multiplied by 12,374,947) less 31,693, or 9,115,007, and each outstanding share of Endwave common stock would convert into 0.909 shares of GigOptix common stock. Thus, if the merger were completed on April 28, 2011, a total of 9,189,580 (9,115,007 plus 74,573) shares of GigOptix common stock would be issued in the merger.

If you are a stockholder of record, you may vote in person at the annual meeting or vote by proxy using the enclosed proxy card. Whether or not you plan to attend the meeting, Endwave urges you to vote by proxy to ensure your vote is counted. You may still attend the meeting and vote in person even if you have already voted by proxy. To vote using the proxy card, simply complete, sign and date the enclosed proxy card and return it promptly in the envelope provided. If you return your signed proxy card to Endwave before the special meeting, Endwave will vote your shares as you direct.

To vote in person at the annual meeting, you must obtain a valid proxy from your broker, bank, or other agent.

GigOptix’ Industry Background

Over the last 30 years, optical networks using light waves to carry digital packets have systematically replaced electrical networks in data-com and telecom due to their inherent technical advantages that enable higher speeds, denser packing of data, lower cost and reduced energy consumption. Cisco recently estimated in its Visual Networking Index that internet video now accounts for more than one-third of all consumer internet traffic and will account for more than 91% of global consumer Internet traffic by 2013; moreover, Cisco forecasts that global internet protocol, or IP, traffic will continue to grow with a 34% compound annual growth rate, or CAGR, from 2009 to 2014 and that mobile IP traffic will grow at a CAGR of 92% from 2010 to 2015 driven to a large degree by increased use of cloud services and viewing of internet video both over fixed and over mobile networks.

Optical technologies such as Dense Wavelength Division Multiplexing, or DWDM, enable multiple independent data streams to travel over the same length of fiber simultaneously without interfering with each other, greatly expanding the potential throughput of the network. These advantages have driven optical networks from ultra-long haul distances greater than 1000 kilometers (trans-oceanic undersea cables) into short distance applications (metropolitan and enterprise networks) and recently even into distances as small as 30 meters (data centers). Additionally, optical interfaces are in early development for very short-range applications, including chip-to-chip interfaces such as those required by PCs and other consumer electronics that will be designed to take advantage of consumer optical standards, which will surpass the abilities of traditional copper circuitry.

Telecommunications and data-communications network systems vendors are producing optical systems increasingly based on 10Gbps, and are moving to 40Gbps and recently introduced 100Gbps standards. Faced with technological and cost challenges, original equipment manufacturers, or OEMs, are focusing on core competencies of software and systems integration, and are relying on component suppliers, such as GigOptix, to design, develop and supply the critical electronic and electro-optic components to perform the key transmit and receive functions. Moreover, the growing complexity of the components and the need to increase the pace of innovation while reducing costs and energy consumption are driving customers to reduce their number of suppliers and favor vendors with comprehensive product portfolios and deeper product and system expertise. GigOptix expects to meet this challenge to become a strategic part of customers’ early product planning, allowing access to technology development and trends, and increasing the likelihood of garnering meaningful market share.

Endwave Corporation

Endwave designs, manufactures and market radio frequency, or RF, products that enable the transmission, reception and processing of high frequency RF signals. Endwave’s products consist of two key product lines, semiconductor devices and integrated transceiver modules:

•

Endwave’s semiconductor product line consists of a wide variety of MMICs including amplifiers, voltage controlled oscillators, up and down converters, variable gain amplifiers, voltage variable attenuators, fixed attenuators and filters. These types of devices are widely used in telecommunications, satellite, defense, security, instrumentation, scientific and consumer systems. While Endwave has developed, produced and sold such devices for several years as components of Endwave’s module products, Endwave first offered them for sale as stand-alone products in the latter part of 2009 and they have not yet become a significant source of revenue for Endwave.

•

Endwave’s integrated transceiver modules combine several electronic functions into a single RF sub-system. Historically, Endwave’s main customers for these products have been telecommunication network OEMs, and system integrators that utilize them in digital microwave radios. More recently Endwave has identified and pursued uses for these products in additional product areas; however these alternate applications have not yet become a significant source of revenue for Endwave.

Endwave’s Industry Background

High-Frequency RF Technology

The applications of RF technology are broad, extending from terrestrial AM radio at the low end of the frequency spectrum, which is less than 1 MHz (megahertz, or million cycles per second), to atmospheric monitoring applications at the high end of the frequency spectrum, which is around 100 GHz (gigahertz, or billion cycles per second). Microwave technology refers to technology for the transmission of signals at high frequencies, from approximately 1 GHz to approximately 20 GHz and millimeter wave technology refers to technology for the transmission of signals at very high frequencies, from approximately 20 GHz to beyond 100 GHz. Endwave’s products employ both microwave and millimeter wave technology. The term microwave is commonly understood in the industries Endwave serves, and that term is used in this prospectus/proxy statement as meaning both microwave and millimeter wave.

Endwave’s products are typically designed to operate at frequencies between 1 GHz and 100 GHz, which are referred to in this report as high-frequency RF. Due to their physical attributes, these frequencies are well-suited for numerous applications requiring the transmission of data at high speeds, detection of physical movement, imaging of inorganic and organic objects and various other types of physical measurements.

Telecommunication Networks

High-frequency transceiver modules and their key constituent components, MMICs, are an integral part of microwave radios, which in turn play a key role in many telecommunication networks. Microwave radio links have a number of applications:

Cellular Telephone Backhaul. The communication link between the cellular base station site and the overall telephone network is referred to as cellular backhaul. This is the most common use of microwave radios. In most parts of the world, cellular backhaul is typically accomplished through the use of microwave radios either because of their ease of deployment and low overall cost relative to available wireline options or because adequate wireline facilities are not available. While in the United States and Canada cellular backhaul has typically been accomplished through the use of wireline facilities, there is a growing trend to migrate to microwave backhaul because wireline systems are not a practical alternative to provide the extremely high backhaul data rates necessitated by contemporary “smart phones” and similar devices.

Carrier Class Trunking. To deploy their networks, communications carriers require high capacity links, or trunk circuits, between major voice and data switching centers. While fiber optic cables are the most common type of trunk circuit facility, microwave radios are often used for portions of these circuits when the intervening terrain, such as mountains or bodies of water, is difficult to traverse or as redundant backup links for the fiber optic network.

Private Voice and Data Networks. When private users, such as companies and universities, deploy stand-alone campus area or metropolitan area voice and data networks, they often encounter situations where it is not possible to access a direct physical path between their facilities due to distance or intervening structures and roads. If third-party wireline facilities are not available or cost-effective, a microwave radio link is often used to provide the network connection. In addition, companies often implement microwave facilities as redundant backup links for their wireline facilities.

technological and cost issues associated with connecting individual access points to the wireline network infrastructure. Endwave believes this need for backhaul represents an opportunity for microwave radios, particularly because the anticipated high bandwidth requirements of fixed wireless access networks are served more cost-effectively by microwave radios than by wireline alternatives.

While transient economic conditions and changing deployment schedules may cause short-term market fluctuations, Endwave believes the long-term prospects for the use of its products and technology in telecommunications networks are good. The continued deployment of mobile networks in developing countries, the continued enhancement of networks in developed regions and the ongoing rate of increases in data traffic all work to increase demand for the types of products Endwave offers.

Defense Systems

High-frequency RF technology is an integral part of various defense systems. Key applications in these markets include:

Radar Systems. Traditional radar systems are configured to detect large objects at significant distances. To add to this capability, many new systems employ complementary high frequency RF radar systems designed to detect small vehicles and personnel. These new systems often use these higher frequencies in order to provide greater resolution. A further use of high frequency radar is airborne imaging equipment that allows pilots to see through low-lying haze and dust much in the same way night vision goggles permit one to see in the dark.

Signal Intelligence Systems. Information about an opposing force can be gathered by monitoring their electronic communications. Systems that gather such information utilize a variety of RF and microwave components to monitor and interpret information over a broad spectrum of potential frequencies that a hostile force might use.

High Capacity Communications. A modern, widely-dispersed military or security force requires communication systems to transmit voice, video and data wherever and whenever it is needed. Many military or security communication systems, whether terrestrial, airborne or satellite, employ microwave technology to meet these requirements. As the data rates in these systems increase, the systems must be able to operate at higher frequencies to take advantage of the transmission bandwidth that is available at those frequencies.

Security Systems

Because millimeter wave energy is both emitted by and reflected off of the human body, various sensors and imaging systems can be constructed to enhance the capability of personnel security systems.

Long Distance Personnel Detection. High-frequency RF signals can be used to detect the presence of humans at significant distances, much in the same way lower frequency radar systems can detect metal objects at a distance. This phenomenon can be employed as a “radar fence” to detect intrusion along lengthy security perimeters such as airport runways, secure compounds and international borders.

Security Portals. Using high-frequency RF signals and holographic image processing techniques, it is possible to create images of the human body through garments and thus detect if the individual is carrying contraband objects or weapons. These systems are used in airport security lanes and for the interdiction of contraband or controlled materials in or out of secure facilities.

Security Cameras. Utilizing security cameras that are capable of detecting and forming images with the high-frequency RF energy emitted by the human body it is possible to observe large areas in search of contraband objects or weapons in a stand-off mode that does not require one to pass through a security portal. These systems are used for loss prevention in warehouse facilities and in large public spaces to protect against terrorist activities.

The increasing concern over terrorist attacks in various public spaces is driving demand for these types of security systems and Endwave believes is creating new opportunities for its products.

Other Applications

Scientific Sensors. Various sorts of physical phenomena can be detected and measured using high-frequency RF signals. In particular, they can detect earth movements, both seismic and volcanic, through cloud cover and can also be used to measure atmospheric disturbances at upper altitudes to aid in weather prediction.

Through-wall Imagers. High-frequency RF energy has the capability to see through common building materials and detect if hidden obstructions, electrical lines, pipes or conduits exist inside of a wall. Devices employing this technology are used to avoid disruptions caused by damaging these hidden items during subsequent construction activities.

Automotive Radar. Advanced automotive radar systems utilize high-frequency RF energy to detect road hazards, other vehicles and roadway barriers and signal the power train to take appropriate action to reduce the risk of a collision or other hazardous event.

The range and breadth of applications for high-frequency RF systems continues to grow. Thus, Endwave believes there will be significant market opportunities for its products and technologies going forward.

The Merger (See page 132)

GigOptix, Merger Sub and Endwave have entered into the merger agreement that provides that, subject to the terms of the merger agreement and Delaware law, Merger Sub will be merged with and into Endwave, with Endwave continuing as the surviving entity and a wholly-owned subsidiary of GigOptix.

If the merger is completed, GigOptix will issue shares of its common stock to holders of Endwave common stock, restricted stock units and in-the-money options. The outstanding shares of Endwave common stock (other than shares subject to perfected appraisal rights and other than shares held by Endwave, Merger Sub, GigOptix or any subsidiary of GigOptix), including shares issued upon settlement of all outstanding restricted stock units to acquire Endwave common stock, will be converted into the right to receive an aggregate number of shares of GigOptix common stock equal to the product of (0.425/0.575) and the number of shares of GigOptix common stock outstanding immediately prior to consummation of the merger, less 42.5% of the number derived from the formula used in calculating the number of the shares of GigOptix common stock to be issued to holders of outstanding Endwave in-the-money options. Endwave stockholders will receive cash for any fractional share of GigOptix common stock that they would otherwise receive in the merger based on the closing price of GigOptix’ common stock as reported on the OTC Bulletin Board on the trading day immediately prior to the effective time of the merger.

exercise price below the closing price of Endwave common stock on the Nasdaq Global Market on April 27, 2011). On April 27, 2011, the closing price of GigOptix’ common stock was $2.60 and the closing price of Endwave’s common stock was $2.40. As a result, if the merger were completed on April 28, 2011, GigOptix would issue 74,573 shares of common stock to the holders of Endwave options. 42.5% of that amount is 31,693. The aggregate number of shares GigOptix common stock that would be issued to the holders of Endwave common stock (including shares issued upon settlement of restricted stock units and assuming no shares are subject to perfected appraisal rights) if the merger closed on April 28, 2011 would be 9,146,700 ((0.425/0.575) multiplied by 12,374,947) less 31,693, or 9,115,007, and each outstanding share of Endwave common stock would convert into 0.909 shares of GigOptix common stock. Altogether, a total of 9,189,580 (9,115,007 plus 74,573) shares of GigOptix common stock would be issued in the merger.

Treatment of Endwave Stock Options and Restricted Stock Units (See page 164)

At the effective time of the merger, all outstanding options to acquire Endwave common stock will terminate and cease to represent a right to acquire Endwave common stock. Options that are “in-the-money” (options that have an exercise price below the closing price of Endwave’s common stock on the Nasdaq Global Market on the trading day prior to the effective time of the merger) will be converted into that number of shares of GigOptix common stock determined by dividing the spread value of such options at closing by the closing price of GigOptix’ common stock on the trading day prior to closing. “Spread value” is the product of the total number of shares subject to the option and the difference between the closing price of Endwave’s common stock on the Nasdaq Global Market on the trading day prior to the effective time of the merger and the option’s per share exercise price. Holders of Endwave stock options that are not in-the-money will not be entitled to receive any shares of GigOptix common stock for those stock options. We believe that treating options in this manner compensates the optionholders for the current realizable value of their options but prevents any future dilution to the holders of Endwave and GigOptix stock that would result if such options were assumed by GigOptix.

At the effective time of the merger, restricted stock units of Endwave common stock that are outstanding immediately prior to the effective time of the merger will terminate and cease to represent a right to acquire Endwave common stock. Each holder of an Endwave restricted stock unit will be entitled to receive a number of shares of GigOptix common stock equal to the product of (i) the number of shares of Endwave common stock issuable upon settlement of the applicable Endwave restricted stock unit, whether or not vested, and (ii) the ratio at which outstanding shares of Endwave common stock will be converted in the merger into the right to receive shares of GigOptix common stock.

Recommendation of Endwave’s Board of Directors (See Page 129).

Endwave’s board of directors unanimously determined that the merger is fair to, advisable and in the best interests of Endwave and its stockholders, and duly approved the merger agreement, the merger and the other transactions contemplated by the merger agreement. Endwave’s board of directors unanimously recommends that Endwave’s stockholders vote “FOR” adoption of the merger agreement. For the factors considered by Endwave’s board of directors in reaching its decision to approve the merger agreement, see “Proposal One—Adoption of the Merger Agreement—Endwave’s Reasons for the Merger” beginning on page 139 of this proxy statement/prospectus. Endwave’s board of directors also unanimously recommends that Endwave stockholders vote “FOR” the adjournment proposal.

The Endwave Special Meeting (See page 129)

A special meeting of the Endwave stockholders will be held on June 17, 2011, starting at 8:00 a.m. local time (unless it is adjourned or postponed to a later date) at Endwave’s offices at 130 Baytech Drive, San Jose, California 95134. The purpose of the special meeting is for Endwave stockholders to consider and vote upon proposals to adopt the merger agreement and approve the potential adjournment of the special meeting.

Common Stock Ownership By Endwave Directors and Officers and Required Vote

At the close of business on the record date for the special meeting, Endwave’s directors and executive officers and their affiliates beneficially owned and had the right to vote 170,554 shares of Endwave common stock at the special meeting, which represents approximately 1.72% of the shares of Endwave common stock entitled to vote at the special meeting.

The affirmative vote of a majority of the shares of Endwave common stock outstanding and entitled to vote as of the record date is required to adopt the merger agreement, and the affirmative vote of the holders of a majority of the voting power of the shares of Endwave common stock present in person or represented by proxy at the special meeting is required to approve the adjournment proposal.

It is expected that Endwave’s directors and executive officers will vote their shares “FOR” the adoption of the merger agreement, although none of them has entered into any agreement requiring them to do so.

Interests of Certain Persons in the Merger (See page 156)

Endwave’s executive officers and directors have financial interests in the merger that are different from, or in addition to, their interests as Endwave stockholders generally. The Endwave board of directors were aware of and considered these interests, among other matters, in evaluating the merger agreement and in recommending that the Endwave stockholders adopt the merger agreement.

Each of Endwave’s executive officers are participants in change in control severance plans sponsored by Endwave, which provide severance and other benefits in the case of qualifying terminations of employment following a change in control, including completion of the merger, that may result in the receipt by such executive officers of cash severance payments and other benefits with a total value of approximately $1.87 million (collectively, not individually, and excluding the value of any accelerated vesting of stock awards).

The following table shows the potential payout to Endwave’s named executive officers under its Senior Executive Officer Severance and Retention Plan and its Executive Officer Severance and Retention Plan in connection with the merger, assuming the closing of the merger and termination of employment occurred on December 31, 2010:


Name	Salary (1)		COBRA Benefits (2)		Option Awards (3)		Total Benefit
John J. Mikulsky(4)	$	987,000	$	105,000	$	30,168	$	1,122,168
Curt P. Sacks	$	220,000	$	15,000	$	9,400	$	244,400
Daniel P. Teuthorn	$	229,000	$	15,000	$	10,441	$	254,441

(1)	Reflects the greater of 18 months’ salary or three months’ salary for each full year of employment for Mr. Mikulsky (42 months) and 12 months’ salary for Mr. Sacks and Mr. Teuthorn.

(2)	Reflects the greater of nine months coverage or 1.5 months coverage for each full year of employment for Mr. Mikulsky (21 months) and 12 months coverage for Mr. Sacks and Mr. Teuthorn.

(3)

Reflects value of options accelerated in the event of termination without cause in connection with a change of control. Because the closing price of Endwave’s common stock on December 31, 2010 was $2.28 and the exercise prices of certain options outstanding and in-the-money on December 31, 2010 were below the closing price, the value of the options that would have been accelerated are reflected above.

(4)

In connection with the proposed merger with GigOptix, it is anticipated that Mr. Mikulsky’s benefit will be reduced to a total of $881,867 in order to maximize the aggregate present value of such benefit without causing any payment to create an excise tax liability under Section 4999 of the Internal Revenue Code of 1986, as amended.

Certain of Endwave’s executive officers will be employed by GigOptix after the merger. Agreements with these executive officers are being negotiated but have not yet been entered into.

Endwave’s directors and executive officers each hold restricted stock units and options to acquire shares of Endwave common stock. Under the terms of the merger agreement and Endwave’s equity incentive plan, the vesting of all outstanding options and restricted stock units to acquire Endwave common stock, not just options and restricted stock units held by directors and executive officers, will accelerate in connection with the transaction regardless of whether the holder’s employment or other service relationship with Endwave terminates. The completion of the merger will result in, among other things, the conversion of restricted stock units and in-the-money options to acquire Endwave common stock into shares of GigOptix common stock as described in this proxy statement/prospectus. As of May 12, 2011, Endwave’s directors and executive officers held unvested options to purchase 203,653 shares of Endwave common stock and unvested restricted stock units for 36,000 shares of Endwave common stock.

Completion of the Merger is Subject to Certain Conditions (See page 174)

•

GigOptix shall have obtained all necessary permits and qualifications required by any state blue sky laws, or otherwise secured an exemption therefrom, in connection with the issuance of GigOptix common stock in the transactions contemplated by the merger agreement, the failure of which to obtain would be reasonably likely to have a material adverse effect on GigOptix or Endwave; and

•

certain of the representations and warranties of GigOptix and Merger Sub being true and correct in all respects, and the remaining representations and warranties being true and correct in all material respects, both as of the date of the merger agreement and the date of the closing of the merger, except (i) for changes specifically permitted by the merger agreement, (ii) that the accuracy of representations and warranties that by their terms speak as of the date of the merger agreement or some other date will be determined as of such date and (iii) where the failure of the representations and warranties to be so true and correct does not have a material adverse effect on GigOptix;

•

GigOptix and Merger Sub will have performed and complied in all material respects with all agreements and obligations required by the merger agreement to be performed or complied with by it on or prior to the date of the closing of the merger;

•

GigOptix shall have obtained the consent of its lender to the completion of the merger.

Further, unless waived by GigOptix, the obligations of GigOptix and Merger Sub to effect the merger will be subject to the fulfillment of each of the following additional conditions on or before the effective time of the merger:

•

Endwave will have performed and complied in all material respects with all agreements and obligations required by the merger agreement to be performed or complied with by it on or prior to the date of the closing of the merger;

•

Endwave will have furnished a certificate of Endwave executed by one of its officers to evidence compliance with the conditions set forth in the previous two items;

as of the closing of the merger, the aggregate number of Endwave shares for which valid demands for appraisal under Delaware law have been made and not withdrawn shall not exceed 10% of the number of issued and outstanding shares of Endwave common stock on the record date for the Endwave special meeting.

Termination of the Merger Agreement

The merger agreement may be terminated at any time prior to the effective time of the merger, whether before or after the approval and adoption of the merger agreement by Endwave stockholders:

•

by mutual written agreement of GigOptix and Endwave duly authorized by the board of directors of each company; or

•

by either Endwave or GigOptix if:

•

the merger shall not have been consummated by June 30, 2011 for any reason; provided, however, that the right to terminate the merger agreement under this provision will not be available to any party whose action or failure to act has been a principal cause of or resulted in the failure of the merger to occur on or before June 30, 2011 and the action or failure to act constitutes a material breach of a covenant of the party set forth in the merger agreement;

•

if a court of competent jurisdiction or other government entity shall have issued an order, decree or ruling or taken any other action, in any case having the effect of permanently restraining, enjoining or otherwise prohibiting the merger, which order, decree, ruling or other action is final and nonappealable;

•

if Endwave’s stockholders do not adopt the merger agreement by reason of the failure to hold a meeting or the failure to obtain the required vote at a meeting of Endwave stockholders; provided, however, that the right to terminate the merger agreement under this provision will not be available to Endwave where the failure to hold a meeting or the failure to obtain the requisite stockholder approval is caused by the action or failure to act of Endwave and the action or failure to act constitutes a material breach by Endwave of its covenants set forth in the merger agreement;

•

(i) the board of directors of Endwave or any committee thereof withdraws or amends or modifies in a manner adverse to GigOptix its recommendation in favor of, the adoption and approval of the merger agreement or the approval of the merger; (ii) Endwave fails to include in this proxy statement/prospectus the recommendation of the board of directors of Endwave in favor of the adoption and approval of the merger agreement and the approval of the merger; (iii) the board of directors of Endwave fails to reaffirm its recommendation in favor of the adoption and approval of the merger agreement and the approval of the merger within ten days after GigOptix requests in writing that such recommendation be reaffirmed at any time following the public announcement of a proposal to acquire Endwave (other than an offer or proposal by GigOptix); (iv) the board of directors of Endwave or any committee thereof shall have approved or recommended any acquisition proposal (other than an offer or proposal by GigOptix); or (v) a tender or exchange offer relating to securities of Endwave is commenced by a person unaffiliated with GigOptix and Endwave does not send to its security holders pursuant to Rule 14e-2 promulgated under the Securities Act, within ten business days after the tender or exchange offer is first published, sent or given, a statement disclosing that Endwave recommends rejection of such tender or exchange offer; or

•

by Endwave, upon a breach of any representation, warranty, covenant or agreement on the part of GigOptix set forth in the merger agreement, or if any representation or warranty of GigOptix becomes untrue, in either case such that certain conditions set forth in the merger agreement would not be satisfied as of the time of the breach or as of the time the representation or warranty becomes untrue, provided that the inaccuracy in GigOptix’ representations and warranties or breach by GigOptix remains uncured on the date that is 20 business days following written notice of the breach or inaccuracy from Endwave to GigOptix. Endwave may not terminate the merger agreement pursuant to this provision if it has materially breached any of its covenants in the merger agreement and remains in breach of the applicable covenants as of the date of the termination; or

•

by GigOptix, upon a breach of any representation, warranty, covenant or agreement on the part of Endwave set forth in the merger agreement, or if any representation or warranty of Endwave becomes untrue, in either case such that the conditions set forth in the merger agreement would not be satisfied as of the time of the breach or as of the time such representation or warranty becomes untrue, provided that the inaccuracy in Endwave’s representations and warranties or breach by Endwave remains uncured on the date that is 20 business days following written notice of the breach or inaccuracy from GigOptix to Endwave. GigOptix may not terminate the merger agreement pursuant to this provision if it has materially breached any of its covenants in the merger agreement and remains in breach of the applicable covenants as of the date of such termination.

Termination Fee and Expenses

On a termination of the merger agreement under certain circumstances, Endwave may be obligated to pay GigOptix a termination fee of $1,000,000 plus certain reasonable documented expenses of GigOptix.

Material U.S. Federal Income Tax Consequences of the Merger (See page 178)

If, as planned and expected, the merger is completed in accordance with the merger agreement and the conditions of the tax opinions being given by Nixon Peabody LLP, counsel to GigOptix, and Cooley LLP, counsel to Endwave, as described in greater detail in “Material U.S. Federal Income Tax Consequences of the Merger”, are otherwise satisfied, Endwave stockholders will not recognize gain or loss upon the receipt of GigOptix common stock in exchange for Endwave stock in connection merger (except to the extent of cash received in lieu of a fractional share of GigOptix common stock). You should read “Material U.S. Federal Income Tax Consequences of the Merger” for a more complete discussion of the U.S. federal income tax consequences of the merger, including the limitations, exceptions, assumptions and conditions set forth therein.

Tax matters can be complicated, and the tax consequences of the transaction to you will depend on your particular tax situation. Accordingly, you are urged to consult your own tax advisors to determine the particular federal, state, local or foreign income, reporting or other tax consequences of the merger to you.

Regulatory Matters (See page 162)

There are no regulatory consents or approvals required to complete the merger.

Appraisal Rights (See page 158)

Endwave stockholders will be entitled to appraisal rights under the Delaware General Corporation Law, or DGCL, and receive payment for the fair value of their Endwave shares if the merger is completed and the dissenting stockholders follow the requirements of Section 262 of the DGCL.

Endwave stockholders who desire to exercise their appraisal rights must not vote in favor of the adoption of the merger agreement, must submit a written demand for an appraisal before the vote on the adoption of the merger agreement and must continue to hold their Endwave shares through the effective date of the merger. Endwave stockholders must also comply with other procedures as required by Section 262 of the DGCL. Endwave stockholders who validly demand appraisal of their shares in accordance with the DGCL and do not withdraw their demand or otherwise forfeit their appraisal rights will not receive the merger consideration. Instead, after completion of the proposed merger, the Court of Chancery of the State of Delaware will determine the fair value of their shares exclusive of any value arising from the proposed merger. This appraisal amount will be paid in cash and could be more than, the same as or less than the value an Endwave stockholder would be entitled to receive under the merger agreement.

A copy of Section 262 of the DGCL is included as Annex D to this proxy statement/prospectus and a summary of this provision is included under “The Merger Agreement—Appraisal Rights” beginning on page 158 of this proxy statement/prospectus. If the holders of more than 10% of the Endwave common stock outstanding on the record date for the special meeting elect to exercise appraisal rights, then GigOptix can elect to terminate the merger agreement.

Comparative Stock Prices and Dividends

GigOptix common stock is quoted on the OTC Bulletin Board under the symbol “GGOX.OB” In connection with the merger, GigOptix is required to use its commercially reasonable efforts to have its common stock listed for trading on the NYSE AMEX. Endwave’s common stock is listed on the Nasdaq Global Market and trades under the symbol “ENWV.”

The NYSE AMEX has notified GigOptix that it has conditionally approved GigOptix’ common stock for listing. Final approval by the NYSE AMEX of the application for listing is subject to certain conditions, some of which are within the control of GigOptix and others that are outside its control. One of the conditions specifically stated by the NYSE AMEX in its notice to GigOptix requires that GigOptix complete the Merger. Another condition specifically stated by the NYSE AMEX in its notice to GigOptix requires that the trading price of its common stock be maintained at or above the minimum price requirement of $2.00 per share for a sustained period of time, generally five trading days, subject to lengthening or shortening by the NYSE AMEX depending on how consistently the stock trades above $2.00 during that period, and that GigOptix maintain a market capitalization of $50 million and a public float of $15 million. GigOptix intends to satisfy those conditions that are within its control. However, there are no assurances that any conditions outside the control of GigOptix will be satisfied. Approval of the listing is not a condition to the parties’ obligations to complete the merger. If any of the conditions are not satisfied, the NYSE AMEX will not approve GigOptix’ listing application, and its common will not be listed for trading on the NYSE AMEX. GigOptix’ common stock will continue to trade on the OTC

Bulletin Board under the symbol “GGOX.OB” unless and until all of the conditions to trading on the NYSE AMEX have been satisfied and the shares begin officially trading on the NYSE AMEX, after which time GigOptix’ common stock will no longer be traded on the OTC Bulletin Board.

The following table sets forth, for the calendar quarters indicated, the high and low sales prices per share of GigOptix common stock, as reported on the OTC Bulletin Board, and per share of Endwave common stock, as reported on the Nasdaq Global Market.


	GigOptix				Endwave

The following table presents the last reported closing sale price per share of GigOptix common stock, as reported on the OTC Bulletin Board, and per share of Endwave common stock, as reported on the Nasdaq Global Market, on February 4, 2011, the last full trading day before the public announcement of the merger, and on April 28, 2011, the last trading day for which this information could be calculated before the filing of this proxy statement/prospectus. This table also presents the merger consideration equivalent proposed for each share of Endwave common stock on each of the specified dates. These illustrative values are calculated by multiplying the closing price of GigOptix common stock on those dates by a conversion ratio of 0.909. This conversion ratio was calculated by assuming that 9,189,580 shares of GigOptix common stock will be issued to holders of Endwave common stock, restricted stock units and stock options pursuant to the merger, which number is calculated based on the number of shares of GigOptix common stock outstanding as of April 28, 2011 (assuming that there are no shares subject to a perfected appraisal process or shares held by Endwave, Merger Subsidiary, GigOptix or any subsidiary of GigOptix). The actual conversion ratio cannot be determined until immediately before the consummation of the merger. The actual conversion ratio may vary significantly from the ratio determined based on the assumptions above.


	GigOptix Common Stock		Endwave Common Stock		Equivalent Per Share Value of Endwave Common Stock
February 4, 2011	$	2.70	$	2.24	$	2.45
April 2011	$	2.55	$	2.38	$	2.32

As of May 12, 2011, GigOptix had 30 holders of record of its common stock and Endwave had 78 holders of record of its common stock.

Neither GigOptix nor Endwave has paid any cash dividends and GigOptix does not anticipate paying any cash dividends for the foreseeable future after completion of the merger.

There are risks associated with approving the merger, combining the businesses of Endwave and GigOptix and holding GigOptix common stock to be issued in the merger. In addition, there are risks associated with not approving the merger, continuing to operate Endwave’s business on a standalone basis and continuing to hold Endwave common stock. Accordingly, in deciding whether to vote for or against the proposals set forth in this proxy statement/prospectus, Endwave stockholders should consider the following risks:

Because the conversion ratio is not adjustable based on the market price of either GigOptix or Endwave common stock, you cannot be sure of the value of the merger consideration that you will receive.

The number of shares of common stock to be issued by GigOptix in the merger is not adjustable based on the market price of either GigOptix or Endwave common stock and the merger agreement may not be terminated as a result of any such changes. The market value of the shares of GigOptix common stock that Endwave stockholders will be entitled to receive when the merger is completed will depend on the market value of shares of GigOptix common stock at that time, which could vary significantly from the market value of shares of GigOptix common stock on the date the merger agreement was executed, the date of this proxy statement/prospectus or the date of the special meeting. Accordingly, at the time of the special meeting, Endwave stockholders will not know or be able to calculate the market value of the consideration they would receive upon completion of the merger. These variations may result from, among other factors, changes in the business, operations, results and prospects of GigOptix, market expectations of the likelihood that the merger will be completed and the timing of completion, the prospects of post-merger operations, the effect of any conditions or restrictions imposed on or proposed with respect to GigOptix by regulatory agencies and authorities, general market and economic conditions and other factors. Endwave stockholders should obtain recent market quotations before they vote on the matters set forth in this proxy statement/prospectus.

GigOptix’ future success will depend in significant part on its ability to utilize Endwave’s cash and cash equivalents and to realize the cost savings, operating efficiencies and new revenue opportunities that it expects to result from the integration of the GigOptix and Endwave businesses. GigOptix’ operating results and financial condition will be adversely affected if GigOptix is unable to integrate successfully the operations of GigOptix and Endwave, fails to achieve or achieve on a timely basis such cost savings, operating efficiencies and new revenue opportunities, or incurs unforeseen costs and expenses or experiences unexpected operating difficulties that offset anticipated cost savings or Endwave’s cash and cash equivalents, in whole or in part. In particular, the integration of GigOptix and Endwave may involve, among other matters, integration of sales, marketing, billing, accounting, manufacturing, engineering, management, personnel, payroll, quality control, regulatory compliance, network infrastructure and other systems and operating hardware and software, some of which may be incompatible and therefore may need to be replaced.

The cost savings estimates expected to result from the merger as set forth in this proxy statement/prospectus do not include one-time adjustments that GigOptix will record in connection with the merger. In addition, the estimates are based upon assumptions by the managements of GigOptix and Endwave concerning a number of factors, including operating efficiencies, the consolidation of functions, and the integration of operations, systems, marketing methods and procedures. These assumptions are uncertain and are subject to significant business, economic and competitive conditions that are difficult to predict and often beyond the control of management.

Endwave will be subject to business uncertainties and contractual restrictions while the merger is pending that could adversely affect its business.

Uncertainty about the effect of the merger on employees and customers may have an adverse effect on Endwave and consequently on GigOptix following the merger. These uncertainties may impair each company’s

ability to attract, retain and motivate key personnel until the merger is completed and for a period of time thereafter, and could cause customers, suppliers and others that deal with Endwave to seek to change existing business relationships with Endwave. Employee retention may be particularly challenging during the pendency of the merger, as employees may experience uncertainty about their future roles with Endwave. If, despite Endwave’s retention efforts, key employees depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with Endwave, Endwave’s business and consequently the business of GigOptix following the merger could be seriously harmed.

Failure to complete the merger could negatively affect GigOptix and Endwave.

If the merger is not completed for any reason, GigOptix and Endwave may be subject to a number of material risks, including the following:

The merger agreement contains customary “no-solicitation” covenants pursuant to which neither Endwave nor GigOptix is permitted to solicit any alternative acquisition proposals, provide any information to any person in connection with any alternative acquisition proposal, participate in any discussions or negotiations relating to any alternative acquisition proposal, approve, endorse or recommend any alternative acquisition proposal, or enter into any agreement relating to any alternative acquisition proposal. The “no-solicitation” provision is subject to certain exceptions that permit the board of directors of each of Endwave and GigOptix, as the case may be, to comply with their respective fiduciary duties, which, under certain circumstances, would enable Endwave or GigOptix, as the case may be, to provide information to, and engage in discussions or negotiations with, third parties with respect to alternative acquisition proposals. Upon termination of the merger agreement under certain circumstances, Endwave may be obligated to pay GigOptix a termination fee of $1,000,000 plus certain reasonable documented expenses of GigOptix. These provisions could discourage a potential acquiror that might have an interest in acquiring all or a significant part of Endwave from considering or proposing that acquisition, even if it were prepared to pay consideration with a higher per share cash or market value than the consideration GigOptix proposes to pay in the merger or might result in a potential competing acquiror proposing to pay a lower per share price to acquire Endwave than it might otherwise have proposed to pay because of the added expense of the termination fee that may become payable to GigOptix in certain circumstances.

Endwave stockholders will have reduced ownership and voting interests in GigOptix and will be able to exercise less influence over management following the merger.

Immediately after the merger, based on the conversion ratios contained in the merger agreement, the pre-merger holders of Endwave common stock and restricted stock units will own that number of shares equal to approximately 42.5% of the outstanding stock of the combined company, less 42.5% of the shares issued in the merger in respect of Endwave stock options. Consequently, stockholders of Endwave will be able to exercise less influence over the management and policies of GigOptix than they currently exercise over the management and policies of Endwave.

There may be a limited public market for shares of GigOptix common stock, and the ability of its stockholders to dispose of their common stock may be limited.

GigOptix common stock has been traded on the OTC Bulletin Board since December 2008. GigOptix cannot foresee the degree of liquidity that will be associated with its common stock. A holder of its common

stock may not be able to liquidate his, her or its investment in a short time period or at the market prices that currently exist at the time the holder decides to sell. The market price for GigOptix’ common stock may fluctuate in the future, and such volatility may bear no relation to its performance.

Substantial future sales of GigOptix’ common stock in the public market could cause GigOptix’ stock price to fall.

The sale of GigOptix’ outstanding common stock or shares issuable upon exercise of options or warrants, or the perception that such sales could occur, could cause the market price of GigOptix common stock to decline. As of April 28, 2011, GigOptix had approximately 12,374,947 shares of common stock, options to purchase 7,384,549 shares of GigOptix’ common stock and warrants to purchase approximately 2,257,159 shares of GigOptix’ common stock outstanding. These shares of common stock, including shares of common stock issued upon exercise of options and warrants, have either been registered under the Securities Act and as such are freely tradable without restriction or are otherwise freely tradeable without restriction (subject to the requirements of Rule 144 under the Securities Act), unless the shares are purchased by “affiliates” as that term is defined in Rule 144 under the Securities Act. Any shares purchased by an affiliate may not be resold except pursuant to an effective registration statement or an applicable exemption from registration, including an exemption under Rule 144 of the Securities Act. In addition, one of the stockholders of GigOptix, the DBSI Liquidating Trust, holds 1,715,161 shares of GigOptix stock and warrants to purchase 1,000,000 shares of GigOptix’ common stock. GigOptix filed a Registration Statement on Form S-1 for the resale registration of the 1,715,161 shares held directly by the DBSI Liquidity Trust, and GigOptix filed an amendment to the registration statement for the purpose of registering the 1,000,000 shares underlying the warrants. GigOptix may issue additional shares of GigOptix common stock in the future in private placements, public offerings or to finance mergers or acquisitions.

The exercise of options and warrants and other issuances of shares of common stock or securities convertible into common stock will dilute the interest of GigOptix stockholders.

As of April 28, 2011, there were outstanding options to purchase an aggregate of 7,384,549 shares of GigOptix common stock at a weighted-average exercise price of $2.66 per share, of which options to purchase 2,480,935 shares at a weighted-average exercise price of $3.58 per share were exercisable as of such date. As of April 28, 2011, there were warrants outstanding to purchase 2,257,159 shares of GigOptix common stock at a weighted average exercise price of $5.86 per share. Certain of these warrants contain adjustment provisions that will reset the exercise price per share of such warrants to any lower price than the existing exercise price at which GigOptix issues shares of its common stock in the future for so long as those warrants are outstanding. The exercise of options and warrants at prices below the market price of GigOptix common stock could adversely affect the price of shares of GigOptix common stock. Additional dilution may result from the issuance of shares of GigOptix capital stock in connection with acquisitions or in connection with financing efforts.

Any issuance of GigOptix common stock that is not made solely to then-existing stockholders proportionate to their interests, such as in the case of a stock dividend or stock split, will result in dilution to each stockholder by reducing his, her or its percentage ownership of the total outstanding shares. Moreover, if GigOptix issues options or warrants to purchase its common stock in the future and those options or warrants are exercised, or if GigOptix issues restricted stock, stockholders may experience further dilution.

In addition, certain warrants to purchase shares of GigOptix’ common stock currently contain an exercise price above the current market price for the common stock. These warrants are known as “above-market” warrants. As a result, it is possible that the holders of these warrants may choose not to exercise them prior to their expiration, in which case GigOptix may not realize any proceeds from their exercise.

The combined company will not be able to fully utilize Endwave’s current net operating loss carryforwards.

As of December 31, 2010, Endwave had a federal net operating loss carryforward of approximately $205.6 million, federal research and development tax credit carryforwards of approximately $2.2 million and a California net operating loss carryforward of approximately $82.2 million. These amounts, if not subject to limitation, would be available to offset the income of Endwave (and, after the merger, GigOptix) that would otherwise be subject to federal and California taxation. However, federal and state net operating loss carryforwards are and will continue to be subject to limitations based on ownership changes of Endwave as well as the combined company after the merger. Due to ownership changes that have occurred to date, only $29.9 million of Endwave’s federal net operating loss carryforwards currently may be used to offset Endwave’s taxable income, which amount would increase (to the extent not utilized) by $4.4 million in 2011 and 2012 and $1.5 million in subsequent tax years through 2027, for total of $61.8 million. The consummation of the merger will result in an additional limitation on the ability to utilize Endwave’s current net operating loss carryforwards. Based on Endwave’s most recent Section 382 analysis and Endwave’s estimate of the value of the shares to be issued in the merger and its balance sheet as of the closing of the merger, and assuming no further ownership changes until the date the merger is consummated, Endwave believes the completion of the merger with GigOptix would have the effect of decreasing the amount of realizable federal net operating loss carryforwards to approximately $400,000 per year, which would have the effect of reducing Endwave’s total realizable federal net operating loss carryforwards from approximately $61.8 million to $7.8 million.

GigOptix and its predecessors have incurred substantial operating losses in the past and it may not be able to achieve profitability in the future.

In addition, GigOptix acquired ChipX in November 2009. Chip X incurred net losses of $5.7 million for the year ended December 31, 2008 and an additional net loss of $3.3 million for the period from January 1, 2009 through the date of acquisition of November 9, 2009.

GigOptix may fail to realize the anticipated benefits of its merger with ChipX.

GigOptix’ future success will depend in significant part on its ability to realize the cost savings, operating efficiencies and new revenue opportunities that are expected to result from the integration of the GigOptix and ChipX businesses. Its operating results and financial condition will be adversely affected if GigOptix is unable to integrate successfully the operations of GigOptix and ChipX, fails to achieve or achieve on a timely basis such cost savings, operating efficiencies and new revenue opportunities, or incurs unforeseen costs and expenses or experiences unexpected operating difficulties that offset anticipated cost savings. In particular, the integration of GigOptix and ChipX may involve, among other matters, integration of sales, marketing, billing, accounting, quality control, management, personnel, payroll, regulatory compliance, network infrastructure and other systems and operating hardware and software, some of which may be incompatible and therefore may need to be replaced.

Any estimates of cost savings are based upon GigOptix’ assumptions concerning a number of factors, including operating efficiencies, the consolidation of functions, and the integration of operations, systems, marketing methods and procedures. These assumptions are uncertain and are subject to significant business, economic and competitive conditions that are difficult to predict and are often beyond GigOptix’ control.

GigOptix’ strategy of growth through acquisition could harm its business.

It is GigOptix’ intent to continue to grow through strategic acquisitions. Successful integration of newly acquired target companies may place a significant burden on its management and internal resources. The diversion of management’s attention and any difficulties encountered in the transition and integration processes could harm GigOptix’ business, financial condition and operating results. In addition, GigOptix may be unable to execute its acquisition strategy, resulting in under-utilized resources and a failure to achieve anticipated growth.

GigOptix faces intense competition and expects competition to increase in the future, which could have an adverse effect on its revenue, revenue growth rate, if any, and market share.

The global semiconductor market in general is highly competitive. GigOptix competes in different target markets to various degrees on the basis of a number of principal competitive factors, including its products’ performance, features and functionality, energy efficiency, size, ease of system design, customer support, products, reputation, reliability and price, as well as on the basis of its customer support, the quality of its product roadmap and its reputation. GigOptix expects competition to increase and intensify as more and larger semiconductor companies as well as the internal resources of large, integrated OEMs, enter its markets. Increased competition could result in price pressure, reduced profitability and loss of market share, any of which could materially and adversely affect GigOptix’ business, revenue, revenue growth rates and operating results.

GigOptix’ competitors range from large, international companies offering a wide range of semiconductor products to smaller companies specializing in narrow markets and internal engineering groups within device manufacturers, some of which may be its customers. GigOptix’ primary competitors include Triquint, Vitesse, Oki, Inphi and Gennum. GigOptix expects competition in the markets in which it participates to increase in the future as existing competitors improve or expand their product offerings. In addition, GigOptix believes that a number of other public and private companies are in the process of developing competing products for digital television and other broadband communication applications. Because GigOptix’ products often are “building block” semiconductors that provide functions that in some cases can be integrated into more complex integrated circuits, GigOptix also faces competition from manufacturers of integrated circuits, some of which may be existing customers that develop their own integrated circuit products.

GigOptix’ ability to compete successfully depends on elements both within and outside of its control, including industry and general economic trends. During past periods of downturns in its industry, competition in the markets in which it operates intensified as manufacturers of semiconductors reduced prices in order to combat production overcapacity and high inventory levels. Many of GigOptix’ competitors have substantially greater financial and other resources with which to withstand similar adverse economic or market conditions in the future. Moreover, the competitive landscape is changing as a result of consolidation within its industry as some of its competitors have merged with or been acquired by other competitors, and other competitors have begun to collaborate with each other. These developments may materially and adversely affect GigOptix’ current and future target markets and its ability to compete successfully in those markets.

If GigOptix fails to develop and introduce new or enhanced products on a timely basis, its ability to attract and retain customers could be impaired and its competitive position could be harmed.

GigOptix operates in a dynamic environment characterized by rapidly changing technologies and industry standards and technological obsolescence. To compete successfully, GigOptix must design, develop, market and sell new or enhanced products that provide increasingly higher levels of performance and reliability and meet the

cost expectations of its customers. The introduction of new products by GigOptix’ competitors, the market acceptance of products based on new or alternative technologies, or the emergence of new industry standards could render its existing or future products obsolete. GigOptix’ failure to anticipate or timely develop new or enhanced products or technologies in response to technological shifts could result in decreased revenue. In particular, GigOptix may experience difficulties with product design, manufacturing, marketing or certification that could delay or prevent its development, introduction or marketing of new or enhanced products. If GigOptix fails to introduce new or enhanced products that meet the needs of its customers or penetrate new markets in a timely fashion, it will lose market share and its operating results will be adversely affected.

GigOptix may require additional capital to continue to fund its operations. If GigOptix needs but does not obtain additional capital, it may be required to substantially limit operations.

GigOptix may not generate sufficient cash from its operations to finance its anticipated operations for the foreseeable future from such operations. Although consummation of the merger with Endwave is expected to improve GigOptix’ cash position and mitigate GigOptix’ near-term liquidity needs, it is anticipated that GigOptix may need to use such cash for its capital needs. Furthermore, to the extent that the merger is not consummated, GigOptix may need to seek funding through public or private financings, including equity financings, and through other arrangements including collaborations. GigOptix could require additional financing sooner than expected if it has poor financial results, including unanticipated expenses, or an unanticipated drop in projected revenues. Such financing may be unavailable when needed or may not be available on acceptable terms. If GigOptix raises additional funds by issuing equity or convertible debt securities, the percentage ownership of its current stockholders will be reduced, and these securities may have rights superior to those of its common stock. If adequate funds are not available to satisfy either short-term or long-term capital requirements, or if planned revenues are not generated, GigOptix may be required to limit its operations substantially. These limitations of operations may include a possible sale or shutdown of portions of its business, reductions in capital expenditures and reductions in staff and discretionary costs.

GigOptix has incurred negative cash flows from operations since inception. For the years ended December 31, 2010 and 2009, GigOptix incurred net losses of $4.4 million and $10.0 million, respectively, and cash outflows from operations of $3.8 million and $4.1 million respectively. As of December 31, 2010 and 2009, GigOptix had an accumulated deficit of $73.4 million and $69.0 million, respectively. GigOptix has incurred significant losses since inception, attributable to GigOptix’ efforts to design and commercialize GigOptix’ products. GigOptix has managed GigOptix’ liquidity during this time through a series of cost reduction initiatives and through increasing GigOptix’ line of credit with GigOptix’ bank. GigOptix’ ability to continue as a going concern is dependent on many events outside of GigOptix’ direct control, including, among other things, obtaining additional financing either privately or through public markets and consumers purchasing GigOptix’ products in substantially higher volumes. During 2010, GigOptix raised approximately $3.9 million in additional equity capital from institutional investors.

GigOptix relies on a limited number of third parties to manufacture, assemble and test its products, and the failure to manage its relationships with its third-party contractors successfully could adversely affect its ability to market and sell its products.

GigOptix does not have its own manufacturing facilities. GigOptix operates an outsourced manufacturing business model that utilizes third-party foundry and assembly and test capabilities. As a result, GigOptix relies on third-party foundry wafer fabrication and assembly and test capacity, including sole sourcing, for many components or products. Currently, GigOptix’ semiconductor devices are manufactured by foundries operated by IBM, Win, Triquint, UMC and SEI. GigOptix also uses third-party contractors for all of its assembly and test operations, including Bourns, Spel, IMT and Sanmina SCI.

Relying on third party manufacturing, assembly and testing presents significant risks to GigOptix, including the following:

The ability and willingness of GigOptix’ third-party contractors to perform is largely outside its control. If one or more of GigOptix’ contract manufacturers or other outsourcers fails to perform its obligations in a timely manner or at satisfactory quality levels, GigOptix’ ability to bring products to market and GigOptix’ reputation could suffer. For example, in the event that manufacturing capacity is reduced or eliminated at one or more facilities, including as a response to the recent worldwide decline in the semiconductor industry, manufacturing could be disrupted, GigOptix could have difficulties fulfilling GigOptix’ customer orders and its net revenue could decline. In addition, if these third parties fail to deliver quality products and components on time and at reasonable prices, GigOptix could have difficulties fulfilling its customer orders, its net revenue could decline and its business, financial condition and results of operations would be adversely affected.

GigOptix does not have any long-term supply contracts with its contract manufacturers or suppliers, and any disruption in its supply of products or materials could have a material adverse effect on its business, revenue and operating results.

GigOptix currently does not have long-term supply contracts with any of its third-party vendors. GigOptix makes substantially all of its purchases on a purchase order basis, and its contract manufacturers are not required to supply it products for any specific period or in any specific quantity. GigOptix expects that it would take approximately nine to twelve months to transition performance of its foundry or assembly services to new providers. Such a transition would likely require a qualification process by its customers or their end customers. GigOptix generally places orders for products with some of its suppliers approximately four to five months prior to the anticipated delivery date, with order volumes based on its forecasts of demand from its customers. Accordingly, if GigOptix inaccurately forecasts demand for its products, it may be unable to obtain adequate and cost-effective foundry or assembly capacity from its third-party contractors to meet its customers’ delivery requirements, or GigOptix may accumulate excess inventories. GigOptix’ third-party contractors have not provided any assurance to it that adequate capacity will be available to GigOptix within the time required to meet additional demand for its products.

Average selling prices of GigOptix’ products could decrease rapidly, which could have a material adverse effect on its revenue and gross margins.

GigOptix may experience substantial period-to-period fluctuations in future operating results due to the erosion of its average selling prices. From time to time, GigOptix has reduced the average unit price of its products in anticipation of competitive pricing pressures, new product introductions by it or its competitors and for other reasons. GigOptix expects that it will have to do so again in the future. If GigOptix is unable to offset

any reductions in its average selling prices by increasing its sales volumes or introducing new products with higher operating margins, its revenue and gross margins will suffer. To maintain its gross margins, GigOptix must develop and introduce new products and product enhancements on a timely basis and continually reduce its and its customers’ costs. Failure to do so would cause GigOptix’ revenue and gross margins to decline.

Due to GigOptix’ limited operating history, it may have difficulty accurately predicting its future revenue and appropriately budgeting its expenses.

GigOptix was incorporated in 2008 and had only a limited operating history from which to predict future revenue. This limited operating experience, combined with the rapidly evolving nature of the markets in which it sells its products, substantial uncertainty concerning how these markets may develop and other factors beyond its control, reduces its ability to accurately forecast quarterly or annual revenue. GigOptix is currently expanding its staffing and increasing its expense levels in anticipation of future revenue growth. If its revenue does not increase as anticipated, it could incur significant losses due to its higher expense levels if it is not able to decrease its expenses in a timely manner to offset any shortfall in future revenue.

GigOptix’ customers require its products and its third-party contractors to undergo a lengthy and expensive qualification process, which may delay and does not assure product sales.

Prior to purchasing GigOptix’ products, its customers require that both GigOptix’ products and GigOptix’ third-party contractors undergo extensive qualification processes, which involve testing of the products in the customer’s system and rigorous reliability testing. This qualification process may continue for six months or more. However, qualification of a product by a customer does not assure any sales of the product to that customer. Even after successful qualification and sales of a product to a customer, a subsequent revision to the product, changes in GigOptix’ customer’s manufacturing process or its selection of a new supplier may require a new qualification process, which may result in delays and in GigOptix holding excess or obsolete inventory. After GigOptix’ products are qualified, it can take an additional six months or more before the customer commences volume production of components or devices that incorporate its products. Despite these uncertainties, GigOptix devotes substantial resources, including design, engineering, sales, marketing and management efforts, to qualifying its products with customers in anticipation of sales. If GigOptix is unsuccessful or delayed in qualifying any of its products with a customer, sales of this product to the customer may be precluded or delayed, which may impede GigOptix’ growth and cause GigOptix’ business to suffer.

GigOptix is subject to order and shipment uncertainties, and differences between GigOptix’ estimates of customer demand and product mix and its actual results could negatively affect GigOptix’ inventory levels, sales and operating results.

GigOptix’ revenue is generated on the basis of purchase orders with GigOptix’ customers rather than long-term purchase commitments. In addition, GigOptix’ customers can cancel purchase orders or defer the shipments of GigOptix’ products under certain circumstances. GigOptix’ products are manufactured using a silicon foundry according to its estimates of customer demand, which requires GigOptix to make separate demand forecast assumptions for every customer, each of which may introduce significant variability into GigOptix’ aggregate estimate. GigOptix has limited visibility into future customer demand and the product mix that its customers will require, which could adversely affect GigOptix’ revenue forecasts and operating margins. Moreover, because GigOptix’ target markets are relatively new, many of its customers have difficulty accurately forecasting their product requirements and estimating the timing of their new product introductions, which ultimately affects their demand for GigOptix’ products. In addition, the rapid pace of innovation in GigOptix’ industry could render significant portions of its inventory obsolete. Excess or obsolete inventory levels could result in unexpected expenses or increases in its reserves that could adversely affect GigOptix’ business, operating results and financial condition. Conversely, if GigOptix were to underestimate customer demand or if sufficient manufacturing capacity were unavailable, GigOptix could forego revenue opportunities, potentially lose market share and damage its customer relationships. In addition, any significant future cancellations or deferrals of

product orders or the return of previously sold products due to manufacturing defects could materially and adversely impact GigOptix’ profit margins, increase GigOptix’ write-offs due to product obsolescence and restrict its ability to fund its operations.

The recent earthquake and related tsunami in Japan has accelerated the rate of orders from certain of GigOptix’ customers and negatively affected certain of its suppliers. If GigOptix is unable to properly manage the supply of products to its customers, there could be a negative impact on GigOptix’ financial position, statement of operations and cash flows.

GigOptix has certain customers and suppliers in Japan. To date, the recent earthquake and related tsunami in Japan has not caused a negative impact on GigOptix’ customers, and in some cases, GigOptix has experienced an acceleration in orders from current customers and new customers that cannot obtain supply from other vendors. To the extent that GigOptix is able to plan its inventory and obtain the necessary materials in a timely manner, GigOptix believes that it can support the acceleration in orders from its current customers as well as potential orders from new customers. If GigOptix cannot procure, process, assemble and test the required materials to support these customers, there could be a negative impact on GigOptix’ financial condition, results of operations and cash flows. GigOptix also has certain suppliers that have been negatively impacted by power shortages and other operational problems as a result of the earthquake and tsunami. While in certain cases GigOptix has inventory of products from these suppliers to support sales in the near-term, to the extent GigOptix cannot obtain materials and products in the correct mix from these suppliers to support purchase orders and sales forecasts from its customers, it could have a negative impact on GigOptix’ financial position, statement of operations and cash flows. In order to support future sales requiring materials from these suppliers, GigOptix may have to place larger orders or orders far in advance than is customary in order to secure adequate supply. To the extent GigOptix carries this additional inventory, GigOptix exposes itself to risks that sales forecasts may not materialize as planned and GigOptix will have to record write-downs of inventory, which would negatively impact its results of operations.

Winning business is subject to lengthy competitive selection processes that require GigOptix to incur significant expenditures. Even if GigOptix begins a product design, a customer may decide to cancel or change its product plans, which could cause GigOptix to generate no revenue from a product and adversely affect GigOptix’ results of operations.

The selection process for obtaining new business typically is lengthy and can require GigOptix to incur significant design and development expenditures and dedicate scarce engineering resources in pursuit of a single customer opportunity. GigOptix may not win the competitive selection process and may never generate any revenue despite incurring significant design and development expenditures. These risks are exacerbated by the fact that some of GigOptix’ customers’ products likely will have short life cycles. Failure to obtain business in a new product design could prevent GigOptix from offering an entire generation of a product, even though this has not occurred to date. This could cause GigOptix to lose revenue and require GigOptix to write off obsolete inventory, and could weaken its position in future competitive selection processes.

After securing new business, GigOptix may experience delays in generating revenue from GigOptix’ products as a result of the lengthy development cycle typically required. GigOptix’ customers generally take a considerable amount of time to evaluate GigOptix’ products. The typical time from early engagement by GigOptix’ sales force to actual product introduction could run from 12 to 24 months. The delays inherent in these lengthy sales cycles increase the risk that a customer will decide to cancel, curtail, reduce or delay its product plans, causing GigOptix to lose anticipated sales. In addition, any delay or cancellation of a customer’s plans could materially and adversely affect GigOptix’ financial results, as GigOptix may have incurred significant expense and generated no revenue. Finally, GigOptix’ customers’ failure to successfully market and sell their products could reduce demand for GigOptix’ products and materially and adversely affect GigOptix’ business, financial condition and results of operations. If GigOptix were unable to generate revenue after incurring substantial expenses to develop any of its products, its business would suffer.

Many of GigOptix’ products will have long sales cycles, which may cause GigOptix to expend resources without an acceptable financial return and which makes it difficult to plan GigOptix’ expenses and forecast GigOptix’ revenue.

Many of GigOptix’ products will have long sales cycles that involve numerous steps, including initial customer contacts, specification writing, engineering design, prototype fabrication, pilot testing, regulatory approvals (if needed), sales and marketing and commercial manufacture. During this time, GigOptix may expend substantial financial resources and management time and effort without any assurance that product sales will result. The anticipated long sales cycle for some of GigOptix’ products makes it difficult to predict the quarter in which sales may occur. Delays in sales may cause GigOptix to expend resources without an acceptable financial return and make it difficult to plan expenses and forecast revenues.

The semiconductor industry is highly cyclical and is characterized by constant and rapid technological change, rapid product obsolescence and price erosion, evolving standards, short product life cycles and wide fluctuations in product supply and demand. The industry is experiencing a significant downturn during the current global recession. These downturns have been characterized by diminished product demand, production overcapacity, high inventory levels and accelerated erosion of average selling prices. The current downturn and any future downturns could have a material adverse effect on GigOptix’ business and operating results. Furthermore, any upturn in the semiconductor industry could result in increased competition for access to third-party foundry and assembly capacity. GigOptix is dependent on the availability of this capacity to manufacture and assemble its products, and its third-party manufacturers have not provided assurances that adequate capacity will be available to GigOptix in the future.

A large proportion of GigOptix’ products are directed at the telecommunications and data communications markets, which continue to be subject to overcapacity.

The technology equipment industry is cyclical and has experienced significant and extended downturns in the past, often in connection with, or in anticipation of, maturing product cycles, and capital spending cycles and declines in general economic conditions. The cyclical nature of these markets has led to significant imbalances in demand, inventory levels and production capacity. It has also accelerated the decrease of average selling prices per unit. GigOptix may experience periodic fluctuations in GigOptix’ financial results because of these or other industry-wide conditions. Developments that adversely affect the telecommunications or data communications markets, including delays in traffic growth and changes in U.S. government regulation, could halt GigOptix’ efforts to generate revenue or cause revenue growth to be slower than anticipated from sales of electro-optic modulators, semiconductors and related products. Reduced spending and technology investment by telecommunications companies may make it more difficult for GigOptix’ products to gain market acceptance. GigOptix’ potential customers may be less willing to purchase new technology such as GigOptix’ technology or invest in new technology development when they have reduced capital expenditure budgets.

GigOptix derives a significant portion of its revenue from a small number of customers and the loss of one or more of these key customers, the diminished demand for GigOptix’ products from a key customer, or the failure to obtain certifications from a key customer or its distribution channel could significantly reduce GigOptix’ revenue and profits.

A relatively small number of customers account for a significant portion of GigOptix’ revenue in any particular period. For instance, Alcatel and contracts with the U.S. government accounted for 11% and 14%, respectively, of GigOptix’ revenue for fiscal year 2010. One or more of GigOptix’ key customers may discontinue operations as a result of consolidation, liquidation or otherwise, or reduce significantly its business with GigOptix due to the current economic conditions. Reductions, delays and cancellation of orders from GigOptix’ key customers or the loss of one or more key customers could significantly further reduce GigOptix’

revenue and profits. There is no assurance that GigOptix’ current customers will continue to place orders with GigOptix, that orders by existing customers will continue at current or historical levels or that GigOptix will be able to obtain orders from new customers.

GigOptix relies on a small number of development contracts with the U.S. Department of Defense and government contractors for a large portion of GigOptix’ revenue. The termination or non-renewal of one or more of these contracts could reduce GigOptix’ future revenue.

Fourteen percent of GigOptix’ revenue for the year ended December 31, 2010 was derived from performance on a limited number of development contracts with various agencies within the U.S. government. Any failure by GigOptix to continue these relationships or significant disruption or deterioration of GigOptix’ relationship with the U.S. Department of Defense may reduce revenues. Government programs must compete with programs managed by other contractors for limited and uncertain levels of funding. The total amount and levels of funding are susceptible to significant fluctuations on a year-to-year basis. GigOptix’ competitors frequently engage in efforts to expand their business relationships with the government and are likely to continue these efforts in the future. In addition, GigOptix’ development contracts with government agencies are subject to potential profit and cost limitations and standard provisions that allow the U.S. government to terminate such contracts at any time at its convenience. Termination of these development contracts, a shift in government spending to other programs in which GigOptix is not involved, or a reduction in government spending generally or defense spending specifically could severely harm GigOptix’ business. GigOptix intends to continue to compete for government contracts and expect such contracts will be a large percentage of GigOptix’ revenue for the foreseeable future. The development contracts in place with various agencies within the U.S. Department of Defense require ongoing compliance with applicable federal procurement regulations. Violations of these regulations can result in civil, criminal or administrative proceedings involving fines, compensatory and punitive damages, restitution and forfeitures, as well as suspensions or prohibitions from entering into such development contracts. Also, the reporting and appropriateness of costs and expenses under these development contracts are subject to extensive regulation and audit by the Defense Contract Audit Agency, or DCAA, an agency of the U.S. Department of Defense. In addition, GigOptix obtains provisional billing rates from the DCAA to bill under government contracts. Any differences between provisional billing rates and actual billed rates may result in an adjustment to revenue. Any failure to comply with applicable government regulations could jeopardize GigOptix’ development contracts and otherwise harm GigOptix’ business.

GigOptix’ future success depends in part on the continued service of its key senior management, design engineering, sales, marketing, and technical personnel and its ability to identify, hire and retain additional, qualified personnel.

GigOptix’ future success depends to a significant extent upon the continued service of GigOptix’ senior management personnel, including GigOptix’ Chief Executive Officer, Dr. Avi Katz and GigOptix’ Chief Technical Officer, Andrea Betti-Berutto. GigOptix does not maintain key person life insurance on any of GigOptix’ executive officers and do not intend to purchase any in the future. The loss of key senior executives could have a material adverse effect on GigOptix’ business. There is intense competition for qualified personnel in the semiconductor and polymer industries, and GigOptix may not be able to continue to attract and retain engineers or other qualified personnel necessary for the development of GigOptix’ business, or to replace engineers or other qualified personnel who may leave GigOptix’ employment in the future. There may be significant costs associated with recruiting, hiring and retaining personnel. Periods of contraction in GigOptix’ business may inhibit GigOptix’ ability to attract and retain GigOptix’ personnel. Loss of the services of, or failure to recruit, key design engineers or other technical and management personnel could be significantly detrimental to GigOptix’ product development or other aspects of GigOptix’ business.

GigOptix is subject to the risks frequently experienced by early stage companies.

The likelihood of GigOptix’ success must be considered in light of the risks frequently encountered by early stage companies, especially those formed to develop and market new technologies. These risks include GigOptix’ potential inability to:

GigOptix’ future growth will suffer if it does not achieve sufficient market acceptance of its products.

GigOptix’ success depends, in part, upon GigOptix’ ability to maintain and gain market acceptance of GigOptix’ products. To be accepted, these products must meet the quality, technical performance and price requirements of GigOptix’ customers and potential customers. The optical communications industry is currently fragmented with many competitors developing different technologies. Some of these technologies may not gain market acceptance. GigOptix’ products, including products based on polymer materials, may not be accepted by OEMs and systems integrators of optical communications networks and consumer electronics. In addition, even if GigOptix achieves some degree of market acceptance for GigOptix’ potential products in one industry, GigOptix may not achieve market acceptance in other industries for which GigOptix is developing products, which market acceptance is critical to meeting GigOptix’ financial targets.

Many of GigOptix’ current products, particularly those based on polymer technology, are either in the development stage or are being tested by potential customers. GigOptix cannot be assured that its development efforts or customer tests will be successful or that they will result in actual material sales, or that such products will be commercially viable.

Achieving market acceptance for GigOptix’ products will require marketing efforts and the expenditure of financial and other resources to create product awareness and demand by customers. It will also require the ability to provide excellent customer service. GigOptix may be unable to offer products that compete effectively due to GigOptix’ limited resources and operating history. Also, certain large corporations may be predisposed against doing business with a company of GigOptix’ limited size and operating history. Failure to achieve broad acceptance of GigOptix’ products by customers and to compete effectively would harm GigOptix’ operating results.

Successful commercialization of current and future products will require GigOptix to maintain a high level of technical expertise.

Technology in GigOptix’ target markets is undergoing rapid change. To succeed in these target markets, GigOptix will have to establish and maintain a leadership position in the technology supporting those markets. Accordingly, GigOptix’ success will depend on GigOptix’ ability to:

GigOptix cannot assure you that it will be able to achieve any of these objectives.

GigOptix’ faces competitive pressures from a variety of companies in GigOptix’ target markets. The telecom, data-com and consumer opto-electronics markets are highly competitive and it expects that domestic and international competition will increase in these markets, due in part to deregulation, rapid technological advances, price erosion, changing customer preferences and evolving industry standards. Increased competition could result in significant price competition, reduced revenues or lower profit margins. Many of GigOptix’ competitors and potential competitors have or may have substantially greater research and product development capabilities, financial, scientific, marketing, and manufacturing and human resources, name recognition and experience than it does. As a result, these competitors may:

Competitors may offer enhancements to existing products, or offer new products based on new technologies, industry standards or customer requirements that are available to customers on a more timely basis than comparable products from GigOptix or that have the potential to replace or provide lower cost alternatives to GigOptix’ products. The introduction of enhancements or new products by competitors could render GigOptix’ existing and future products obsolete or unmarketable. Each of these factors could have a material adverse effect on GigOptix’ business, financial condition and results of operations.

GigOptix may be unable to obtain effective intellectual property protection for GigOptix’ potential products and technology.

Any intellectual property that GigOptix has or may acquire, license or develop in the future may not provide meaningful competitive advantages. GigOptix’ patents and patent applications, including those it licenses, may be challenged by competitors, and the rights granted under such patents or patent applications may not provide meaningful proprietary protection. For example, there are patents held by third parties that relate to polymer materials and electro-optic devices. These patents could be used as a basis to challenge the validity or limit the scope of GigOptix’ patents or patent applications. A successful challenge to the validity or limitation of the scope of GigOptix’ patents or patent applications could limit GigOptix’ ability to commercialize the technology and, consequently, reduce revenues.

Moreover, competitors may infringe GigOptix’ patents or those that it licenses, or successfully avoid these patents through design innovation. To combat infringement or unauthorized use, GigOptix may need to resort to litigation, which can be expensive and time-consuming and may not succeed in protecting GigOptix’ proprietary rights. In addition, in an infringement proceeding, a court may decide that GigOptix’ patents or other intellectual property rights are not valid or are unenforceable, or may refuse to stop the other party from using the intellectual property at issue on the ground that it is non-infringing. Policing unauthorized use of GigOptix’ intellectual property is difficult and expensive, and it may not be able to, or have the resources to, prevent misappropriation of GigOptix’ proprietary rights, particularly in countries where the laws may not protect these rights as fully as the laws of the United States.

GigOptix also relies on the law of trade secrets to protect unpatented technology and know-how. GigOptix tries to protect this technology and know-how by limiting access to those employees, contractors and strategic partners with a need to know this information and by entering into confidentiality agreements with these parties. Any of these parties could breach the agreements and disclose GigOptix’ trade secrets or confidential information to competitors, or such competitors might learn of the information in other ways. Disclosure of any trade secret not protected by a patent could materially harm GigOptix’ business.

GigOptix may be subject to patent infringement claims, which could result in substantial costs and liability and prevent GigOptix from commercializing potential products.

Third parties may claim that GigOptix’ potential products or related technologies infringe their patents. Any patent infringement claims brought against GigOptix may cause GigOptix to incur significant expenses, divert the attention of management and key personnel from other business concerns and, if successfully asserted, require GigOptix to pay substantial damages. In addition, as a result of a patent infringement suit, GigOptix may be forced to stop or delay developing, manufacturing or selling potential products that are claimed to infringe a patent covering a third party’s intellectual property unless that party grants GigOptix rights to use its intellectual property. GigOptix may be unable to obtain these rights on acceptable terms, if at all. Even if GigOptix is able to obtain rights to a third party’s patented intellectual property, these rights may be non-exclusive, and therefore competitors may obtain access to the same intellectual property. Ultimately, GigOptix may be unable to commercialize GigOptix’ potential products or may have to cease some business operations as a result of patent infringement claims, which could severely harm GigOptix’ business.

If GigOptix’ potential products infringe the intellectual property rights of others, it may be required to indemnify customers for any damages they suffer. Third parties may assert infringement claims against GigOptix’ current or potential customers. These claims may require GigOptix to initiate or defend protracted and costly litigation on behalf of customers, regardless of the merits of these claims. If any of these claims succeed, GigOptix may be forced to pay damages on behalf of these customers or may be required to obtain licenses for the products they use. If GigOptix cannot obtain all necessary licenses on commercially reasonable terms, GigOptix may be unable to continue selling such products.

The technology that GigOptix licenses from various third parties may be subject to government rights and retained rights of the originating research institution.

GigOptix licenses technology from various companies or research institutions, such as the University of Washington. Many of these partners and licensors have obligations to government agencies or universities. Under their agreements, a government agency or university may obtain certain rights over the technology that GigOptix has developed and licensed, including the right to require that a compulsory license be granted to one or more third parties selected by the government agency.

In addition, GigOptix’ partners often retain certain rights under their licensing agreements, including the right to use the technology for noncommercial academic and research use, to publish general scientific findings from research related to the technology, and to make customary scientific and scholarly disclosures of information relating to the technology. It is difficult to monitor whether such partners limit their use of the technology to these uses, and GigOptix could incur substantial expenses to enforce its rights to this licensed technology in the event of misuse.

If GigOptix fails to develop and maintain the quality of GigOptix’ manufacturing processes, GigOptix’ operating results would be harmed.

The manufacture of GigOptix’ products is a multi-stage process that requires the use of high-quality materials and advanced manufacturing technologies. With respect to GigOptix’ polymer-based products, polymer-related device development and manufacturing must occur in a highly controlled, clean environment to minimize particles and other yield- and quality-limiting contaminants. In spite of stringent quality controls, weaknesses in process control or minute impurities in materials may cause a substantial percentage of a product in a lot to be defective. If GigOptix is unable to develop and continue to improve on GigOptix’ manufacturing processes or to maintain stringent quality controls, or if contamination problems arise, GigOptix’ operating results would be harmed.

The complexity of GigOptix’ products may lead to errors, defects and bugs, which could result in the necessity to redesign products and could negatively impact GigOptix’ reputation with customers.

Products as complex as GigOptix’ may contain errors, defects and bugs when first introduced or as new versions are released. Delivery of products with production defects or reliability, quality or compatibility problems could significantly delay or hinder market acceptance of GigOptix’ products or result in a costly recall and could damage GigOptix’ reputation and adversely affect GigOptix’ ability to retain existing customers and to attract new customers. In particular, certain products are customized or designed for integration into specific network systems. If GigOptix’ products experience defects, GigOptix may need to undertake a redesign of the product, a process that may result in significant additional expenses.

GigOptix may also be required to make significant expenditures of capital and resources to resolve such problems. There is no assurance that problems will not be found in new products after commencement of commercial production, despite testing by GigOptix, GigOptix’ suppliers and GigOptix’ customers.

GigOptix could be exposed to significant product liability claims that could be time-consuming and costly and impair GigOptix’ ability to obtain and maintain insurance coverage.

GigOptix may be subject to product liability claims if any of GigOptix’ products are alleged to be defective or harmful. Product liability claims or other claims related to GigOptix’ potential products, regardless of their outcome, could require GigOptix to spend significant time and money in litigation, divert management’s time and attention from other business concerns, require GigOptix to pay significant damages, harm GigOptix’ reputation or hinder acceptance of GigOptix’ products. Any successful product liability claim may prevent GigOptix from obtaining adequate product liability insurance in the future on commercially reasonable terms. Any inability to obtain sufficient insurance coverage at an acceptable cost or otherwise to protect against

potential product liability claims could impair GigOptix’ ability to commercialize GigOptix’ products. In addition, certain of GigOptix’ products are sold under warranties. The failure of GigOptix’ products to meet the standards set forth in such warranties could result in significant expenses to GigOptix.

If GigOptix fails to effectively manage GigOptix’ growth, and effectively transition from GigOptix’ focus on research and development activities to commercially successful products, GigOptix’ business could suffer.

Failure to manage growth of operations could harm GigOptix’ business. To date, a large number of GigOptix’ activities and resources have been directed at the research and development of GigOptix’ technologies and development of potential related products. The transition from a focus on research and development to being a vendor of products requires effective planning and management. Additionally, growth arising from the expected synergies from future acquisitions will require effective planning and management. Future expansion will be expensive and will likely strain management and other resources.

There is no assurance that GigOptix will be able to accomplish these tasks effectively or otherwise effectively manage GigOptix’ growth.

GigOptix’ business, financial condition and operating results would be harmed if it does not achieve anticipated revenue.

From time to time, in response to anticipated long lead times to obtain inventory and materials from outside contract manufacturers, suppliers and foundries, GigOptix may need to order materials in advance of anticipated customer demand. This advance ordering may result in excess inventory levels or unanticipated inventory write-downs if expected orders fail to materialize, or other factors render GigOptix’ products less marketable. If GigOptix is forced to hold excess inventory or incur unanticipated inventory write-downs, GigOptix’ financial condition and operating results could be materially harmed.

GigOptix’ expense levels are relatively fixed and are based on GigOptix’ expectations of future revenue. GigOptix will have limited ability to reduce expenses quickly in response to any revenue shortfalls. Changes to production volumes and impact of overhead absorption may result in a decline in GigOptix’ financial condition or liquidity.

GigOptix could suffer unrecoverable losses on GigOptix’ customers’ accounts receivable, which would adversely affect GigOptix’ financial results.

GigOptix’ operating cash flows are dependent on the continued collection of receivables. GigOptix’ accounts receivable as of December 31, 2010 increased by $1.6 million or 43% compared to the balance at December 31, 2009. GigOptix could suffer additional accounting losses as well as a reduction in liquidity if a customer is unable to pay. A significant increase in uncollectible accounts would have an adverse impact on GigOptix’ business, liquidity and financial results.

The industry and markets in which GigOptix competes are subject to consolidation, which may result in stronger competitors, fewer customers and reduced demand.

There has been industry consolidation among communications IC companies, network equipment companies and telecommunications companies in the past. This consolidation is expected to continue as

companies attempt to strengthen or hold their positions in evolving markets. Consolidation may result in stronger competitors, fewer customers and reduced demand, which in turn could have a material adverse effect on GigOptix’ business, operating results, and financial condition.

GigOptix’ operating results are subject to fluctuations because GigOptix has international sales.

International sales account for a large portion of GigOptix’ revenue and may account for an increasing portion of future revenue. The revenue derived from international sales may be subject to certain risks, including:

GigOptix is subject to regulatory compliance related to GigOptix’ operations.

GigOptix is subject to various U.S. governmental regulations related to occupational safety and health, labor and business practices. Failure to comply with current or future regulations could result in the imposition of substantial fines, suspension of production, alterations of GigOptix’ production processes, cessation of operations, or other actions, which could harm GigOptix’ business.

GigOptix may incur liability arising from GigOptix’ use of hazardous materials.

GigOptix’ business and facilities are subject to a number of federal, state and local laws and regulations relating to the generation, handling, treatment, storage and disposal of certain toxic or hazardous materials and waste products that are used or generated in GigOptix’ operations. Many of these environmental laws and regulations subject current or previous owners or occupiers of land to liability for the costs of investigation, removal or remediation of hazardous materials. In addition, these laws and regulations typically impose liability regardless of whether the owner or occupier knew of, or was responsible for, the presence of any hazardous materials and regardless of whether the actions that led to their presence were taken in compliance with the law. GigOptix’ domestic facilities use various chemicals in manufacturing processes that may be toxic and covered by various environmental controls. These hazardous materials may be stored on site. The waste created by use of these materials is transported off-site by an unaffiliated waste hauler. Many environmental laws and regulations require generators of waste to take remedial actions at an off-site disposal location even if the disposal was conducted lawfully. The requirements of these laws and regulations are complex, change frequently and could become more stringent in the future. Failure to comply with current or future environmental laws and regulations could result in the imposition of substantial fines, suspension of production, alteration of production processes, cessation of operations or other actions, which could severely harm GigOptix’ business.

GigOptix has previously identified material weaknesses in GigOptix’ internal control over financial reporting. If it fails to remedy the material weaknesses or otherwise fail to maintain effective internal control over financial reporting, the accuracy and timing of GigOptix’ financial reporting may be adversely affected.

In connection with the preparation of GigOptix’ consolidated financial statements for the years ended December 31, 2010 and 2009, material weaknesses in GigOptix’ internal controls over financial reporting, as defined in rules established by the Public Company Accounting Oversight Board, were identified. A “material weakness” is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements would not be prevented or detected on a timely basis. The material weaknesses were attributed to GigOptix not maintaining a sufficient complement of personnel with an appropriate level of accounting knowledge, experience and training in the application of generally accepted accounting principles commensurate with GigOptix’ financial reporting requirements. GigOptix has adopted a remediation plan that GigOptix is in the process of implementing in conjunction with its proposed acquisition of Endwave. A key component of the remediation plan will be the addition of accounting personnel with the appropriate level of accounting knowledge, experience, and training in the application of generally accepted accounting principles commensurate with the financial reporting requirements of a public company. GigOptix will continue to update and upgrade its internal processes and systems relating to financial reporting. GigOptix expects to remediate the material weaknesses during 2011.

In addition, other material weaknesses or significant deficiencies in GigOptix’ internal control over financial reporting may be identified in the future. If GigOptix fails to remediate the material weakness or fail to implement required new or improved controls, or encounter difficulties in their implementation, it could harm GigOptix’ operating results, cause failure to meet GigOptix’ SEC reporting obligations on a timely basis or result in material misstatements in GigOptix’ annual or interim financial statements.

GigOptix may be unable to export some of GigOptix’ potential products or technology to other countries, convey information about GigOptix’ technology to citizens of other countries or sell certain products commercially, if the products or technology are subject to U.S. export or other regulations.

GigOptix is developing certain products that it believes the U.S. government and other governments may be interested in using for military and information gathering or antiterrorism activities. U.S. government export regulations may restrict GigOptix from selling or exporting these potential products into other countries, exporting GigOptix’ technology to those countries, conveying information about GigOptix’ technology to citizens of other countries or selling these potential products to commercial customers. GigOptix may be unable to obtain export licenses for products or technology if necessary. GigOptix currently cannot assess whether national security concerns would affect GigOptix’ potential products and, if so, what procedures and policies GigOptix would have to adopt to comply with applicable existing or future regulations.

GigOptix is subject to risks associated with the imposition of legislation and regulations relating to the import or export of high technology products. GigOptix cannot predict whether quotas, duties, taxes or other charges or restrictions upon the importation or exportation of GigOptix’ products will be implemented by the United States or other countries.

Various laws and regulations potentially affect the import and export of GigOptix’ products, including export control, tax and customs laws. Furthermore, some customer purchase orders and agreements are governed by foreign laws, which may differ significantly from laws in the United States. As a result, GigOptix’ ability to enforce GigOptix’ rights under such agreements may be limited compared with GigOptix’ ability to enforce GigOptix’ rights under agreements governed by laws in the United States.

Sales to customers located outside of the United States comprised 49% and 51% of GigOptix’ revenue for 2010 and 2009, respectively. In addition, GigOptix has a subsidiary overseas (Switzerland) that records its

operating expenses in a foreign currency. Because sales of GigOptix’ products have been denominated to date primarily in U.S. dollars, increases in the value of the U.S. dollar could increase the price of GigOptix’ products so that they become relatively more expensive to customers in the local currency of a particular country, leading to a reduction in sales and profitability in that country. Future international activity may result in increased foreign currency denominated sales. Gains and losses on the conversion to U.S. dollars of accounts receivable, accounts payable and other monetary assets and liabilities arising from international operations may contribute to fluctuations in GigOptix’ results of operations. GigOptix currently does not have hedging or other programs in place to protect against adverse changes in the value of the U.S. dollar as compared to other currencies to minimize potential adverse effects.

Restrictive covenants under GigOptix’ credit facility with Silicon Valley Bank may adversely affect its operations.

GigOptix’ loan and security agreement with Silicon Valley Bank contains a number of restrictive covenants that will impose significant operating and financial restrictions on GigOptix’ ability to, without prior written approval from Silicon Valley Bank:

The receipt of Silicon Valley Bank’s prior written approval of the proposed merger with Endwave is a condition to Endwave’s obligation to effect the closing of the merger. A failure to comply with the covenants contained in GigOptix’ loan and security agreement could result in an event of default under the agreement that, if not cured or waived, could result in the acceleration of the indebtedness and have a material adverse effect on GigOptix’ business, financial condition and results of operations.

GigOptix’ quarter-to-quarter performance may vary substantially, and this variance, as well as general market conditions, may cause GigOptix’ stock price to fluctuate greatly and potentially expose GigOptix to litigation.

The revenues for GigOptix product lines and its quarterly operating results may vary significantly based on many factors, including:

GigOptix bases its current and future expense estimates, in large part, on estimates of future revenue, which is difficult to predict. GigOptix expects to continue to make significant operating and capital expenditures in the area of research and development and to invest in and expand production, sales, marketing and administrative systems and processes. GigOptix may be unable to, or may elect not to, adjust spending quickly enough to offset any unexpected revenue shortfall. If GigOptix’ increased expenses are not accompanied by increased revenue in the same quarter, its quarterly operating results would be harmed.

In future quarters, GigOptix’ results of operations may fall below the expectations of investors and the trading price of its common stock may decline as a consequence. GigOptix believes that quarter-to-quarter comparisons of its operating results will not be a good indication of future performance and should not be relied upon to predict the future performance of its stock price. In the past, companies that have experienced volatility in the market price of their stock have often been subject to securities class action litigation. GigOptix may be the target of this type of litigation in the future. Securities litigation could result in substantial costs and divert GigOptix’ attention from other business concerns, which could seriously harm its business.

Provisions in GigOptix’ amended and restated certificate of incorporation and GigOptix’ amended and restated bylaws may prevent takeover attempts that could be beneficial to GigOptix’ stockholders.

Provisions of the GigOptix’ amended and restated certificate of incorporation and provisions of the GigOptix’ amended and restated bylaws could discourage a takeover of GigOptix even if a change of control of GigOptix would be beneficial to the interests of its stockholders. These charter provisions include the following:

Endwave has had a history of losses and may not be profitable in the future.

Endwave had a net loss from continuing operations of $8.1 million in 2010. Endwave also had a net loss from continuing operations of $10.6 million and $4.0 million for the years ended December 31, 2009 and 2008, respectively. There is no guarantee that Endwave will achieve or maintain profitability in the future.

Endwave depends on a small number of key customers in the mobile communication industry for a significant portion of its revenues. If Endwave loses any of its major customers or there is any material reduction in orders for Endwave’s products from any of these customers, Endwave’s business, financial condition and results of operations would be adversely affected. In addition, consolidation in this industry could result in delays or cancellations of orders for Endwave’s products, adversely impacting its results of operations.

Endwave depends, and expects to continue to depend, on a relatively small number of mobile communication customers for a significant part of its revenues. The loss of any of Endwave’s major customers or any material reduction in orders from any such customers would have a material adverse effect on Endwave’s business, financial condition and results of operations. In 2010, three customers each accounted for greater than 10% of total revenues and combined they accounted for 93% of Endwave’s total revenues, the largest of which was Nokia Siemens Networks, which accounted for 52% of Endwave’s total revenues. In 2009, two customers accounted for 88% of Endwave’s total revenues and no other customer accounted for more than 10% of its total revenues.

The mobile communication industry has undergone significant consolidation in the past few years. For example, during January 2011, Ceragon Networks Ltd. entered into a definitive agreement to merge with Nera Networks AS. The acquisition of one of Endwave’s major customers in this market, or one of the communications service providers supplied by one of Endwave’s major customers, could result in delays or cancellations of orders for Endwave’s products and, accordingly, delays or reductions in its anticipated revenues and reduced profitability or increased net losses.

Endwave’s semiconductor product line will require it to incur significant expenses and may not be successful.

Endwave’s semiconductor product line will require it to incur expenses to design, test, manufacture and market these products including the purchase of inventory, supplies and capital equipment. The future success of this semiconductor product line will depend on Endwave’s ability to develop these products in a cost-effective and timely manner and to market them effectively. The development of Endwave’s products is complex, and from time to time Endwave may experience delays in completing the development and introduction of its new products or fail to efficiently manufacture such products in the early production phase. The semiconductor product line may have little immediate impact on Endwave’s revenue because a new standard product may not generate meaningful revenue. In the meantime, Endwave will have incurred expenses to design, produce and market the products, and may not recover these expenses if demand for the product fails to reach forecasted levels, which may adversely affect Endwave’s operating results.

Because of the shortages of some components and Endwave’s dependence on single source suppliers and custom components, Endwave may be unable to obtain an adequate supply of components of sufficient quality in a timely fashion, or may be required to pay higher prices or to purchase components of lesser quality.

Many of Endwave’s products are customized and must be qualified with its customers. This means that Endwave cannot change components in its products easily without the risks and delays associated with requalification. Accordingly, while a number of the components Endwave uses in its products are made by multiple suppliers, Endwave may effectively have single source suppliers for some of these components. Further, Endwave has recently experienced extended lead times for many components.

In addition, Endwave currently purchases a number of components, some from single source suppliers, including, but not limited to:

Any delay or interruption in the supply of these or other components could impair Endwave’s ability to manufacture and deliver its products, harm its reputation and cause a reduction in its revenues. In addition, any increase in the cost of the components that Endwave uses in its products could make its products less competitive and lower Endwave’s margins. In the past, Endwave suffered from shortages of and quality issues with various components. These shortages and quality issues adversely impacted Endwave’s product revenues and could reappear in the future. Endwave’s single source suppliers could enter into exclusive agreements with or be acquired by one of its competitors, increase their prices, refuse to sell their products to Endwave, discontinue products or go out of business. Even to the extent alternative suppliers are available to Endwave and their components are qualified with Endwave’s customers on a timely basis, identifying them and entering into arrangements with them may be difficult and time consuming, and they may not meet Endwave’s quality standards. Endwave may not be able to obtain sufficient quantities of required components on the same or substantially the same terms.

Competitive conditions often require Endwave to reduce prices and, as a result, require Endwave to reduce its costs in order to be profitable.

Over the past year, Endwave reduced the prices of many of its telecommunication products in order to remain competitive and Endwave expects market conditions will cause it to reduce its prices again in the future. In order to reduce its per-unit cost of product revenues, Endwave must continue to design and re-design products to utilize lower cost materials and improve its manufacturing efficiencies. The combined effects of these actions may be insufficient to achieve the cost reductions needed to maintain or increase its gross margins or achieve profitability.

Endwave’s operating results may be adversely affected by substantial quarterly and annual fluctuations and market downturns.

Endwave’s revenues, earnings and other operating results have fluctuated in the past and its revenues, earnings and other operating results may fluctuate in the future. These fluctuations are due to a number of factors, many of which are beyond Endwave’s control. These factors include, among others, global economic conditions, overall growth in Endwave’s target markets, the ability of Endwave’s customers to obtain adequate capital, U.S. export law changes, changes in customer order patterns, customer consolidation, availability of components from Endwave’s suppliers, the gain or loss of a significant customer, changes in product mix and market acceptance of Endwave’s products and its customers’ products. These factors are difficult to forecast, and these, as well as other factors, could materially and adversely affect Endwave’s quarterly or annual operating results.

Endwave relies on the semiconductor foundry operations of third-party semiconductor foundries to manufacture the integrated circuits sold directly to its customers and contained in its products. The loss of Endwave’s relationship with any of these foundries without adequate notice would adversely impact its ability to fill customer orders and could damage its customer relationships.

Endwave utilizes both industry standard semiconductor components and its own custom-designed semiconductor devices. However, Endwave does not own or operate a semiconductor fabrication facility, or foundry, and relies on a limited number of third parties to produce its custom-designed components. If any of Endwave’s semiconductor suppliers is unable to deliver semiconductors to it in a timely fashion, the resulting

delay could severely impact its ability to fulfill customer orders and could damage its relationships with its customers. In addition, the loss of Endwave’s relationship with or access to any of the semiconductor foundries it currently uses for the fabrication of custom designed components and any resulting delay or reduction in the supply of semiconductor devices to Endwave, would severely impact Endwave’s ability to fulfill customer orders and could damage its relationships with its customers.

Endwave may not be successful in forming alternative supply arrangements that provide it with a sufficient supply of gallium arsenide devices. Gallium arsenide devices are used in a substantial portion of the products Endwave manufactures. Because there are a limited number of semiconductor foundries that use the particular process technologies Endwave selects for its products and that have sufficient capacity to meet Endwave’s needs, using alternative or additional semiconductor foundries would require an extensive qualification process that could prevent or delay product shipments and revenues. Endwave estimates that it may take up to six months to shift production of a given semiconductor circuit design to a new foundry.

Endwave relies heavily on a Thailand facility of HANA, a contract manufacturer, to produce its RF modules and to package its microwave and millimeter wave integrated circuits. If HANA is unable to produce or package these modules and circuits in sufficient quantities or with adequate quality, or it chooses to terminate Endwave’s manufacturing arrangement, Endwave will be forced to find an alternative manufacturer and may not be able to fulfill its production commitments to its customers, which could cause sales to be delayed or lost and could harm Endwave’s reputation.

Endwave outsources the assembly and testing of its products to a Thailand facility of HANA, a contract manufacturer. Endwave plans to continue this arrangement as a key element of its operating strategy. If HANA does not provide Endwave with high quality products and services in a timely manner, terminates its relationship with Endwave, or is unable to produce its products due to financial difficulties or political instability, Endwave may be unable to obtain a satisfactory replacement to fulfill customer orders on a timely basis. In the event of an interruption of supply from HANA, sales of Endwave’s products could be delayed or lost and its reputation could be harmed. Endwave’s latest manufacturing agreement with HANA expires in October 2011, but will renew automatically for successive one-year periods unless either party notifies the other of its desire to terminate the agreement at least one year prior to the expiration of the term. No such notification has been sent to or received from HANA. In addition, either party may terminate the agreement without cause upon 365 days prior written notice to the other party, and either party may terminate the agreement if the non-terminating party is in material breach and does not cure the breach within 30 days after notice of the breach is given by the terminating party. There can be no guarantee that HANA will not seek to terminate its agreement with Endwave.

A prior misclassification of certain products under the Export Administration Regulations may result in liability for Endwave.

In December 2009, Endwave sought and obtained a formal commodity classification from the Department of Commerce’s Bureau of Industry and Security, or BIS, regarding certain amplifier products rated to operate between 34 and 40 GHz. Prior to such request, Endwave believed based on its internal review that the products and related technology were properly classified as EAR99 and that export licenses were not required to any destination in which Endwave had operations or sold products. In response to its commodity classification request, however, BIS determined that Endwave’s MMIC amplifiers rated to operate between 34 and 40 GHz are classified under Export Classification Control Number, or ECCN, 3A001, which controls MMIC power amplifiers rated for operation at frequencies exceeding 31.8 GHz up to and including 37.5 GHz without regard to power output or fractional bandwidth limits. Products falling under ECCN 3A001 are controlled for national security purposes and are subject to export licensing requirements for most countries. Similarly, technology for the development or production of items controlled under ECCN 3A001 falls under ECCN 3E001. Exports of such technology are likewise controlled for national security purposes and subject to restrictive licensing requirements. License exceptions are available under the Export Administration Regulations for items and technology classified under ECCNs 3A001 and 3E001, respectively.

In March 2011, Endwave submitted a voluntary self-disclosure to BIS detailing the affected transactions. In May 2011, Endwave received BIS authorization to release the affected products. Because Endwave was unable to ship certain transceiver products in the first quarter while the authorization was pending, its revenues were adversely affected in the first quarter. Even though BIS approval was obtained, Endwave may be responsible for monetary penalties for the misclassification.

Endwave’s products may contain component, manufacturing or design defects or may not meet its customers’ performance criteria, which could cause Endwave to incur significant repair expenses, harm its customer relationships and industry reputation, and reduce its revenues and profitability.

Endwave has experienced manufacturing quality problems with its products in the past and may have similar problems in the future. As a result of these problems, Endwave has replaced components in some products, or replaced the product, in accordance with its product warranties. Endwave’s product warranties typically last twelve to thirty months. As a result of component, manufacturing or design defects, Endwave may be required to repair or replace a substantial number of products under its product warranties, incurring significant expenses as a result. Further, Endwave’s customers may discover latent defects in its integrated circuits and module products that were not apparent when the warranty period expired. These latent defects may cause Endwave to incur significant repair or replacement expenses beyond the normal warranty period. In addition, any component, manufacturing or design defect could cause Endwave to lose customers or revenues or damage its customer relationships and industry reputation.

Endwave may not be able to design its products as quickly as its customers require, which could cause it to lose sales and may harm its reputation.

Existing and potential customers typically demand that Endwave design products for them under difficult time constraints. In the current market environment, the need to respond quickly is particularly important. If Endwave is unable to commit the necessary resources to complete a project for a potential customer within the requested timeframe, it may lose a potential sale. Endwave’s ability to design products within the time constraints demanded by a customer will depend on the number of product design professionals who are available to focus on that customer’s project and the availability of professionals with the requisite level of expertise is limited. Endwave has, in the past, expended significant resources on research and design efforts on potential customer products that did not result in additional revenue.

Each of Endwave’s communication products is designed for a specific range of frequencies. Because different national governments license different portions of the frequency spectrum for the mobile communication market, and because communications service providers license specific frequencies as they become available, in order to remain competitive Endwave must adapt its products rapidly to use a wide range of different frequencies. This may require the design of products at a number of different frequencies simultaneously. This design process can be difficult and time consuming, could increase Endwave’s costs and could cause delays in the delivery of products to Endwave’s customers, which may harm Endwave’s reputation and delay or cause it to lose revenues.

Endwave’s customers often have specific requirements that can be at the forefront of technological development and therefore difficult and expensive to meet. If Endwave is not able to devote sufficient resources to these products, or experiences development difficulties or delays, Endwave could lose sales and damage its reputation with those customers.

Endwave depends on its key personnel. Skilled personnel in Endwave’s industry can be in short supply. If Endwave is unable to retain its current personnel or hire additional qualified personnel, its ability to develop and successfully market its products would be harmed.

Endwave believes that its future success depends upon its ability to attract, integrate and retain highly skilled managerial, research and development, manufacturing and sales and marketing personnel. Skilled

personnel in Endwave’s industry can be in short supply. As a result, Endwave’s employees are highly sought after by competing companies and its ability to attract skilled personnel is limited. To attract and retain qualified personnel, Endwave may be required to grant large stock option or other stock-based incentive awards, which may harm its operating results or be dilutive to its other stockholders. Endwave may also be required to pay significant base salaries and cash bonuses, which could harm its operating results.

Due to its relatively small number of employees and the limited number of individuals with the skill set needed to work in its industry, Endwave is particularly dependent on the continued employment of its senior management team and other key personnel. If one or more members of Endwave’s senior management team or other key personnel were unable or unwilling to continue in their present positions, these persons would be very difficult to replace, and Endwave’s ability to conduct its business successfully could be seriously harmed. Endwave does not maintain key person life insurance policies.

The length of Endwave’s sales cycle requires it to invest substantial financial and technical resources in a potential sale before it knows whether the sale will occur. There is no guarantee that the sale will ever occur and if Endwave is unsuccessful in designing integrated circuits and module products for a particular generation of a customer’s products, it may need to wait until the next generation of that product to sell its products to that particular customer.

Endwave’s products are highly technical and the sales cycle can be long. Endwave’s sales efforts involve a collaborative and iterative process with its customers to determine their specific requirements either in order to design an appropriate solution or to transfer the product efficiently to Endwave’s offshore contract manufacturer. Depending on the product and market, the sales cycle can take anywhere from 2 to 24 months, and Endwave incurs significant expenses as part of this process without any assurance of resulting revenues. Endwave generates revenues only if its product is selected for incorporation into a customer’s system and that system is accepted in the marketplace. If Endwave’s product is not selected, or the customer’s development program is discontinued, Endwave generally will not have an opportunity to sell its product to that customer until that customer develops a new generation of its system. There is no guarantee that Endwave’s product will be selected for that new generation system. The length of Endwave’s product development and sales cycle makes Endwave particularly vulnerable to the loss of a significant customer or a significant reduction in orders by a customer because Endwave may be unable to quickly replace the lost or reduced sales.

Endwave may not be able to manufacture and deliver its products as quickly as its customers require, which could cause Endwave to lose sales and would harm its reputation.

Endwave may not be able to manufacture products and deliver them to its customers at the times and in the volumes they require. Manufacturing delays and interruptions can occur for many reasons, including, but not limited to:

Manufacturing Endwave’s products is complex. The yield, or percentage of products manufactured that conform to required specifications, can decrease for many reasons, including materials containing impurities, equipment not functioning in accordance with requirements or human error. If Endwave’s yield is lower than it expects, Endwave may not be able to deliver products on time. For example, in the past, Endwave has on occasion experienced poor yields on certain products that have prevented it from delivering products on time and have resulted in lost sales. If Endwave fails to manufacture and deliver products in a timely fashion, its reputation may be harmed, it may jeopardize existing orders and lose potential future sales, and it may be forced to pay penalties to its customers.

Although Endwave does have long-term commitments from many of its customers, they are not for fixed quantities of product. As a result, Endwave must estimate customer demand, and errors in its estimates could have negative effects on its cash, inventory levels, revenues and results of operations.

Endwave has been required historically to place firm orders for products and manufacturing equipment with its suppliers up to six months prior to the anticipated delivery date and, on occasion, prior to receiving an order for the product, based on its forecasts of customer demands. Endwave’s sales process requires it to make multiple demand forecast assumptions, each of which may introduce error into its estimates. If Endwave overestimates customer demand, Endwave may allocate resources to manufacturing products that it may not be able to sell when it expects, if at all. As a result, Endwave would have additional usage of cash, excess inventory and overhead expense, which would harm its financial results. On occasion, Endwave has experienced adverse financial results due to excess inventory and excess manufacturing capacity. For example, the second quarter of 2010 included a $1.5 million write-off of inventory associated with excess materials related to a rapid drop in sales of a legacy product for a major customer’s radio platform.

Conversely, if Endwave underestimates customer demand or if insufficient manufacturing capacity were available, it would lose revenue opportunities, market share and damage its customer relationships. On occasion, Endwave has been unable to adequately respond to unexpected increases in customer purchase orders and was unable to benefit from this increased demand. There is no guarantee that Endwave will be able to adequately respond to unexpected increases in customer purchase orders in the future, in which case Endwave may lose the revenues associated with those additional purchase orders and its customer relationships and reputation may suffer.

Any failure to protect Endwave’s intellectual property appropriately could reduce or eliminate any competitive advantage Endwave has.

Endwave’s success depends, in part, on its ability to protect its intellectual property. Endwave relies primarily on a combination of patent, copyright, trademark and trade secret laws to protect its proprietary technologies and processes. As of December 31, 2010, Endwave had 43 United States patents issued, many with associated foreign filings and patents. Its issued patents include those relating to basic circuit and device designs, semiconductors, Endwave’s multilithic microsystems technology and system designs. Its issued United States patents expire between 2013 and 2028. Endwave maintains a vigorous technology development program that routinely generates potentially patentable intellectual property. Its decision as to whether to seek formal patent protection is done on a case by case basis and is based on the economic value of the intellectual property, the anticipated strength of the resulting patent, the cost of pursuing the patent and an assessment of using a patent as a strategy to protect the intellectual property.

To protect its intellectual property, Endwave regularly enters into written confidentiality and assignment of rights to inventions agreements with its employees, and confidentiality and non-disclosure agreements with third parties, and generally controls access to and distribution of its documentation and other proprietary information. These measures may not be adequate in all cases to safeguard the proprietary technology underlying Endwave’s products. It may be possible for a third party to copy or otherwise obtain and use Endwave’s products or technology without authorization, develop similar technology independently or attempt to design around Endwave’s patents. In addition, effective patent, copyright, trademark and trade secret protection may be

unavailable or limited outside of the United States, Europe and Japan. Endwave may not be able to obtain any meaningful intellectual property protection in other countries and territories. Additionally, Endwave may, for a variety of reasons, decide not to file for patent, copyright, or trademark protection outside of the United States. Moreover Endwave occasionally agrees to incorporate a customer’s or supplier’s intellectual property into its designs, in which case Endwave has obligations with respect to the non-use and non-disclosure of that intellectual property. Endwave also licenses technology from other companies, including Northrop Grumman Corporation. There are no limitations on Endwave’s rights to make, use or sell products Endwave may develop in the future using the chip technology licensed to it by Northrop Grumman Corporation. Steps taken by Endwave to prevent misappropriation or infringement of its intellectual property or the intellectual property of its customers, may not be successful. Litigation may be necessary in the future to enforce Endwave’s intellectual property rights, to protect its trade secrets or to determine the validity and scope of proprietary rights of others, including Endwave’s customers. Litigation of this type could result in substantial costs and diversion of Endwave’s resources.

Endwave may receive in the future notices of claims of infringement of other parties’ proprietary rights. In addition, the invalidity of its patents may be asserted or prosecuted against Endwave. Furthermore, in a patent or trade secret action, Endwave could be required to withdraw the product or products as to which infringement was claimed from the market or redesign products offered for sale or under development. Endwave has also at times agreed to indemnification obligations in favor of its customers and other third parties that could be triggered upon an allegation or finding of its infringement of other parties’ proprietary rights. These indemnification obligations would be triggered for reasons including Endwave’s sale or supply to a customer or other third parties of a product that was later discovered to infringe upon another party’s proprietary rights. Irrespective of the validity or successful assertion of such claims, Endwave would likely incur significant costs and diversion of its resources with respect to the defense of such claims. To address any potential claims or actions asserted against it, Endwave may seek to obtain a license under a third party’s intellectual property rights. However, in such an instance, a license may not be available on commercially reasonable terms, if at all.

With regard to Endwave’s pending patent applications, it is possible that no patents may be issued as a result of these or any future applications or the allowed patent claims may be of reduced value and importance. If they are issued, any patent claims allowed may not be sufficiently broad to protect Endwave’s technology. Further, any existing or future patents may be challenged, invalidated or circumvented thus reducing or eliminating their commercial value. The failure of any patents to provide protection to Endwave’s technology might make it easier for its competitors to offer similar products and use similar manufacturing techniques.

Endwave is exposed to fluctuations in the market values of its investment portfolio.

Although Endwave has not experienced any material losses on its cash, cash equivalents and short-term investments, future declines in their market values could have a material adverse effect on Endwave’s financial condition and operating results. Although its portfolio has no direct investments in auction rate or sub-prime mortgage securities, Endwave’s overall investment portfolio is currently and may in the future be concentrated in cash equivalents including money market funds. If any of the issuers of the securities Endwave holds default on their obligations, or their credit ratings are negatively affected by liquidity, credit deterioration or losses, financial results, or other factors, the value of Endwave’s cash equivalents and short-term and long-term investments could decline and result in a material impairment.

Endwave’s failure to compete effectively could reduce its revenues and margins.

Among suppliers in the mobile communication market who provide integrated transceivers to radio OEMs, Endwave primarily competes with Compel Electronics SpA, Filtronic plc, and Microelectronics Technology Inc. Additionally, there are mobile communication OEMs, such as Ericsson and NEC Corporation, that use their own captive resources for the design and manufacture of their transceiver modules, rather than using suppliers like

Endwave. To the extent that mobile communication OEMs presently, or may in the future, produce their own transceiver modules, Endwave loses the opportunity to provide its modules to them. However, when Endwave launched it semiconductor product line, it gained the opportunity to provide integrated circuits to all radio OEMs.

Endwave’s failure to comply with any applicable environmental regulations could result in a range of consequences, including fines, suspension of production, excess inventory, sales limitations and criminal and civil liabilities.

Due to environmental concerns, the need for lead-free solutions in electronic components and systems is receiving increasing attention within the electronics industry as companies are moving towards becoming compliant with the RoHS Directive. The RoHS Directive is European Union legislation that restricts the use of a number of substances, including lead, after July 2006. Endwave believes that its products impacted by these regulations are compliant with the RoHS Directive and that materials will continue to be available to meet these regulations. However, it is possible that unanticipated supply shortages or delays or excess non-compliant inventory may occur as a result of these new regulations. Failure to comply with any applicable environmental regulations could result in a range of consequences, including loss of sales, fines, suspension of production, excess inventory and criminal and civil liabilities.

Government regulation of the communications industry could limit the growth of the markets that Endwave serves or could require costly alterations of its current or future products.

The markets that Endwave serves are highly regulated. Communications service providers must obtain regulatory approvals to operate broadband wireless access networks within specified licensed bands of the frequency spectrum. Further, the Federal Communications Commission and foreign regulatory agencies have adopted regulations that impose stringent RF emissions standards on the communications industry that could limit the growth of the markets that Endwave serves or could require costly alterations of Endwave’s current or future products.

Endwave’s failure to continue to develop new or improved semiconductor process technologies could impair its competitive position.

Endwave’s future success depends in part upon its ability to continue to gain access to the current semiconductor process technologies in order to adapt to emerging customer requirements and competitive market conditions. If Endwave fails to keep abreast of the new and improved semiconductor process technologies as they emerge, it may lose market share, which could adversely affect Endwave’s operating results.

The segment of the semiconductor industry in which Endwave participates is intensely competitive, and Endwave’s inability to compete effectively would harm its business.

The markets for Endwave’s products are extremely competitive, and are characterized by rapid technological change and continuously evolving customer requirements. Many of Endwave’s competitors have significantly greater financial, technical, manufacturing, sales and marketing resources than Endwave does. As a result, Endwave’s competitors may develop new technologies, enhancements of existing products or new products that offer price or performance features superior to Endwave’s products. In addition, Endwave’s competitors may be perceived by prospective customers to offer financial and operational stability superior to Endwave’s.

Endwave expects competition in its markets to intensify as new competitors enter the RF, microwave and millimeter wave component market, existing competitors merge or form alliances, and new technologies emerge. If Endwave is not able to compete effectively, its market share and revenue could be adversely affected and its business and results of operations could be harmed.

The market price of Endwave’s common stock has fluctuated historically and is likely to fluctuate in the future.

The price of Endwave’s common stock has fluctuated widely since its initial public offering in October 2000. In 2010, the lowest daily sales price for Endwave’s common stock was $2.00 and the highest daily sales price for Endwave’s common stock was $3.61. In 2009, the lowest daily sales price for Endwave’s common stock was $1.36 and the highest daily sales price for its common stock was $3.43. The market price of Endwave’s common stock can fluctuate significantly for many reasons, including, but not limited to:

It is likely that Endwave’s operating results in one or more future quarters may be below the expectations of security analysts and investors. In that event, the trading price of Endwave’s common stock would likely decline. In addition, the stock market has experienced extreme price and volume fluctuations. These market fluctuations can be unrelated to the operating performance of particular companies and the market prices for securities of technology companies have been especially volatile. Future sales of substantial amounts of Endwave’s common stock, or the perception that such sales could occur, could adversely affect prevailing market prices for its common stock. Additionally, future stock price volatility for Endwave’s common stock could provoke the initiation of securities litigation, which may divert substantial management resources and have an adverse effect on Endwave’s business, operating results and financial condition. Endwave’s existing insurance coverage may not sufficiently cover all costs and claims that could arise out of any such securities litigation. Endwave anticipates that prices for its common stock will continue to be volatile.

Endwave has a few stockholders that each own a large percentage of Endwave’s outstanding capital stock and, as a result of their significant ownership, are able to significantly affect the outcome of matters requiring stockholder approval.

As of April 28, 2011, Endwave’s five largest stockholders together owned approximately 40% of Endwave’s outstanding common stock. Because most matters requiring approval of Endwave’s stockholders require the approval of the holders of a majority of the shares of Endwave’s outstanding capital stock present in person or by proxy at a meeting of stockholders, the significant ownership interest of these stockholders allows them to significantly affect the election of Endwave’s directors and the outcome of corporate actions requiring stockholder approval. This concentration of ownership may also delay, deter or prevent a change in control and may make some transactions more difficult or impossible to complete without their support, even if the transaction is favorable to Endwave’s stockholders as a whole.

Endwave’s certificate of incorporation, bylaws and arrangements with executive officers could delay or prevent a change in control.

Endwave is subject to certain Delaware anti-takeover laws by virtue of its status as a Delaware corporation. These laws prevent Endwave from engaging in a merger or sale of more than 10% of its assets with any stockholder, including all affiliates and associates of any stockholder, who owns 15% or more of Endwave’s outstanding voting stock, for three years following the date that the stockholder acquired 15% or more of Endwave’s voting stock, unless Endwave’s board of directors approved the business combination or the transaction that resulted in the stockholder becoming an interested stockholder, or upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation, or the business combination is approved by Endwave’s board of directors and authorized by at least 66 2/3% of Endwave’s outstanding voting stock not owned by the interested stockholder. A corporation may opt out of the Delaware anti-takeover laws in its charter documents; however, Endwave has not chosen to do so. Endwave’s certificate of incorporation and bylaws include a number of provisions that may deter or impede hostile takeovers or changes of control of management, including a staggered board of directors, the elimination of the ability of stockholders to act by written consent, discretionary authority given to Endwave’s board of directors as to the issuance of preferred stock, and indemnification rights for Endwave’s directors and executive officers. Additionally, Endwave has adopted a Stockholder Rights Plan, providing for the distribution of one preferred share purchase right for each outstanding share of common stock, that may lead to the delay or prevention of a change in control that is not approved by Endwave’s board of directors. Endwave has a Senior Executive Officer Severance Retention Plan, an Executive Officer Severance Plan and a Key Employee Severance and Retention Plan that provide for severance payments and the acceleration of vesting of a percentage of certain stock options granted to its executive officers and certain senior, non-executive employees under specified conditions. These plans may make Endwave a less attractive acquisition target or may reduce the amount a potential acquirer may otherwise be willing to pay for Endwave.

GigOptix is a leading supplier of electronic and electro-optical semiconductor products that enable high-speed telecommunications and data-communications networks globally. GigOptix’ products convert signals between electrical and optical formats for transmitting and receiving data over fiber optic networks, a critical function in optical communications equipment. GigOptix is creating innovations in both telecommunications and data-communications applications for fast growing markets in 10Gbps, 40Gbps and 100Gbps drivers, receiver ICs, electro–optic modulator components and multi-chip-modules, or MCM. GigOptix believes that its expertise in semiconductor electro-optical and optical technologies has helped it create a broad portfolio of products that addresses customer demand for performance at higher speeds, over wider temperature ranges, in smaller sizes, and at lower power consumption compared to other products currently available in the market. GigOptix views itself as a strategic vendor to a number of GigOptix’ customers given GigOptix’ early engagement in their product design plans. GigOptix has well-established relationships with many of the leading telecommunications and data-communications network systems vendors such as Alcatel-Lucent and other “Tier-One” equipment vendors in the United States, Europe and Asia, as well as leading industrial, aerospace and defense customers.

Telecommunications and data-communications networks are becoming increasingly congested due to the growing demand for high bandwidth applications by consumers and enterprises. This bandwidth constraint has caused network service providers to turn to component vendors like GigOptix to provide solutions that maximize bandwidth and reliability while minimizing cost. Increasing the communications data rate in networks has been an important element of easing network congestion, and, as a result, network service providers are in process of upgrading their 10Gbps systems to 40Gbps and 100Gbps equipment deployments throughout their networks. GigOptix focuses on the 10Gbps and above markets, which GigOptix believes present the fastest growing and primary market opportunity in the communications industry.

Since inception, GigOptix has expanded its customer base, acquired and integrated four businesses with complementary products and customers, and in so doing expanded GigOptix’ product line from a few 10Gbps ultra-long reach electronic modulator drivers to a line of over 100 products that includes drivers, receivers and modulators for 10 to 100Gbps applications and custom ASICs. GigOptix’ direct sales force is based in 5 countries and is supported by more than 50 channel representatives and distributors that are selling GigOptix’ products throughout North America, Europe, Japan and Asia. In 2010, GigOptix shipped over 90 products to over 100 customers.

Over the past several years, communications networks have undergone significant challenges as network operators pursue more profitable service offerings while reducing operating costs. The growing demand for bandwidth due to the explosion of data and video across networks by enterprises and consumers has driven service providers to continuously add high speed access such as Wi-Fi, WiMax, 3G, DSL, cable and FTTx, as well as converging their separate voice and data networks into a single IP-based high capacity integrated network to easily manage and provision these services. Other high bandwidth applications such as e-mail, music, video downloads and streaming, on-line social networks, on-line gaming, and VOD or IPTV are also challenging network service providers to supply increasing bandwidth to their customers and results in increased network utilization across the entire core and edge of wireline, wireless and cable networks. Additionally, enterprises and institutions are managing their rapidly escalating demand for data and bandwidth and are upgrading and deploying high speed local, storage and wide area networks (LANs, SANs and WANs, respectively). U.S. Defense and Homeland Security efforts also add to the demand for bandwidth, as vast amounts of data are generated though sophisticated surveillance and defense network applications. The U.S. government and its contractors are incorporating optical technologies into its systems and infrastructure to address these challenges.

Optical networking technologies support higher speeds, added features and offer greater interoperability to accommodate higher bandwidth requirements at a lowest cost. Leading network systems vendors such as Alcatel-Lucent and Cisco are producing optical systems for carriers increasingly based on 10Gbps and 40Gbps speeds including multi-service switches, DWDM transport terminals, access multiplexers, routers, Ethernet switches and other networking systems. Mirroring the convergence of telecommunications and data-communications networks, these systems vendors are increasingly addressing both telecommunications and data-communications applications and are also looking to converge their network equipment offerings to a single product. Faced with technological and cost challenges of building fully integrated systems that can handle voice, data and video, OEMs are re-focusing on core competencies of software and systems integration, and relying on outside module and component suppliers for the design, development and supply of critical electro–optic products that perform the critical transmit and receive functions.

The performance requirements of communications applications and the technical challenges associated with the data-communications and telecommunications markets present difficult obstacles to service providers and equipment designers that serve those markets. The core challenges of processing and transmitting high quality broadband streams include:

GigOptix offers a comprehensive 10Gbps and 40Gbps transceiver product portfolio and is one of the first companies in the developing market for 100Gbps products. GigOptix combines high performance analog and mixed signal design skills, with experience in integrated systems, interoperability, power management and size optimization. GigOptix believes customers choose to work with GigOptix for several reasons including:

Superior Performance: GigOptix believes its performance advantage is derived from industry leading drivers, receivers, modulators and superior integration and module design capabilities. GigOptix’ core III-V and silicon semiconductor, as well as TFPS technology knowledge allows GigOptix to design products that exceed the current performance, power, size, temperature and reliability requirements of GigOptix’ customers. GigOptix recently introduced a 100 Gbps quad-driver built from indium phosphide that is the market’s first 100Gbps driver. GigOptix’ single, 4 and 12 channel VCSEL drivers and receivers have ultra low-power consumption and use less than 10mW to stream 1Gbps. GigOptix has also developed 10Gbps drivers and receivers for outdoor, non-temperature controlled environments that enable higher capacity in GigOptix’ customers’ next generation data center systems.

Broad Product Line: GigOptix has a comprehensive portfolio of products for telecommunications, data-communications, defense and industrial applications designed for speeds of 10Gbps and beyond. GigOptix’ products support a wide range of data rates, protocols, transmission distances and industry standards. This wide product offering allows GigOptix to serve as a “one-stop shop” to GigOptix’ customers in offering them a comprehensive product arsenal, as well as allowing GigOptix to reduce costs as it utilizes pre-existing design building-blocks. GigOptix’ portfolio consists of the following product ranges:

Power Consumption: GigOptix’ designs and enabling technologies utilize efficient circuit techniques and material technology to reduce energy usage. For example, GigOptix has demonstrated a 10Gbps short-reach optical link that consumes less than 100mW across 100 meter of fiber, representing a 75% reduction over the previous generation of products.

Size Reduction: GigOptix’ designs have small footprints. GigOptix recently announced its LX8401 40Gbps TFPS modulator is nearly half the size of competing products enabling an overall smaller transponder design. Similarly, comparable solutions competing with GigOptix’ GX6261 40Gbps DQPSK driver require 40% more board space. Moreover, GigOptix’ GX62455 100Gbps driver integrates four 32Gbps drivers into a single package thereby reducing the total system size while also improving electrical performance.

Cost Reduction: GigOptix is skilled in designing and utilizing a number of semiconductor process technologies such as indium phosphide, gallium arsenide, silicon germanium and silicon CMOS. This portfolio of technology solutions provides the flexibility to optimize the cost/performance of GigOptix’ products to the challenge at hand. For instance, GigOptix’ new portfolio of 10Gbps, 40Gbps and 100Gbps TIAs were designed using silicon germanium and this enables lower production costs compared with competing TIA solutions using indium phosphide. This coupled with the ability to integrate more complex logic functions into the TIA designs offer compelling value to

GigOptix’ customers. GigOptix provides a broad portfolio of solutions that customers are now beginning to leverage to extract further volume discounts by consolidating their purchasing power on one vendor.

Integration: GigOptix’ vision is to leverage its broad portfolio of products to integrate optical modulators monolithically onto GigOptix’ semiconductor chips. The close coupling of optical and electronic components will realize the maximum performance at high speeds while ensuring the smallest size, potentially lower costs and improved interoperability performance. GigOptix believes that its step-wise approach to this goal is aligned to deliver continuously more integrated products along the innovation path starting with bundling in the system level going to package level on to chip level. For instance, GigOptix is currently funded by the Air Force Research Labs to develop an integrated modulator-driver capable of 200Gbps optical transmission, which is seen as critical to enable lightweight, ultra-high bandwidth optical transceivers to on the road to supporting tera-scale data processing. Integrating optical modulators monolithically onto semiconductor chips coupled with innovative driver design topologies can enable implementation of a monolithic optical modulator/driver component.

Partnership: Through a deep understanding both of the system level challenges faced by GigOptix’ customers developing optical transponders and transceivers and of the capabilities and limitations of GigOptix’ technology, GigOptix is able to suggest and implement new system partitioning concepts to ease manufacturing, increase yields and reduce power and cost. For example through the addition of certain design recommendations, GigOptix is able to guide GigOptix’ customers to simplify system manufacturing using GigOptix’ designs.

Technology Leadership: GigOptix’ products are built on a foundation of semiconductor and electro-optic polymer technologies supported by over 20 years of innovation and research and development experience that has resulted in more than 100 patents awarded and patent applications pending worldwide. GigOptix’ technology innovation extends from the design of ultra high speed semiconductor integrated circuits, monolithic microwave integrated circuit design, multi-chip modules, electro-optic thin-film polymer materials, and optical modulator design. These areas of competence include signal integrity, thermal models, power consumption, integration of multiple ICs into sub-system multi-chip module components, and molecular science of electro-optic polymers. The many years of experience allows GigOptix to design high performance solutions. For this reason GigOptix was selected as a partner to a Tier 1 equipment supplier to develop 100Gbps modulator drivers for the first commercially available 100Gbps systems to be launched in 2010. Additionally, GigOptix’ ASIC portfolio and team has the competency in low cost silicon CMOS design and high volume manufacturing. GigOptix believes this will be an important asset in the future transition of optics to consumer applications that call for low cost, high volume designs. GigOptix conducts its research both independently, through contractual relationships with U.S. government agencies and in cooperation with customers. GigOptix is committed to conduct fundamental research into the integration of electronic and electro-optic, or EO, components using semiconductor and EO polymers as a source of differentiation.

Horizontal Business Model: GigOptix deploys a horizontal business model as opposed to a vertical integration model since it is GigOptix’ mission to serve the broad customer base in the optical communications and defense markets with best in class components. GigOptix believes this will be driven by the system vendor end customers’ desire for continuous price reduction as volumes increase and will be enabled by the growth of capable component suppliers such as GigOptix as well as the availability of high quality electronics contract manufacturers, or ECMs. GigOptix cultivates the “Virtual Vertical” model, which is based on strong relationships with ECMs and other component vendors in the supply chain with aligned objectives.

GigOptix’ objective is to be the leading provider of high performance electronic and electro-optic components for the optically and wireless connected digital world, growing through both organic and strategic means. Elements of GigOptix’ strategy include the following:

Focus on High Growth Market Opportunities. GigOptix will continue to focus its product development resources on high growth market segments both within the markets GigOptix currently serves as well as in new

markets that utilize GigOptix’ core technologies. GigOptix will continue to invest substantially in products for 40Gbps and 100Gbps applications and selectively target new products for the 10Gbps markets where GigOptix can sustain a differentiation. GigOptix believes high growth opportunities exist even within more established communications segments by virtue of introducing innovative device and system architectures as well as business models to disrupt the established players and value chain relationships. Outside of telecom and data communications, GigOptix is able to reuse the same designs re-characterized for RF systems used in defense applications such as phased array radar, super-computers and in wireless applications, such as point-to-point back-haul systems.

Grow Customer Base. GigOptix intends to continue to broaden GigOptix’ strategic relationship with key customers by maximizing design wins across their product lines. GigOptix intends to continue to leverage the approved vendor status GigOptix has with these key customers to qualify GigOptix’ products into additional optical and wireless systems, a process that is accelerated when GigOptix had already been qualified in a customer’s systems. GigOptix is adding sales and technical support staff to better serve key customers, markets and regions. GigOptix also intends to add to GigOptix’ number of strategic relationships by selectively targeting certain existing customers with whom GigOptix is not yet a strategic vendor. GigOptix will expand its development efforts with these customers through initiatives including providing specialized sales and support resources, holding technology forums to align GigOptix’ product development effort and implementing custom manufacturing linkages.

Engage Customers Early in their Product Planning Cycle. By engaging GigOptix’ customers early in their system design process, GigOptix gains critical information regarding their system requirements and objectives that influences GigOptix’ component design. GigOptix’ sales force, product marketing teams and developmental engineers engage regularly with GigOptix’ customers to understand their product development plans. Additionally, for certain key customers, which are referred to as GigOptix’ “Lighthouse” customers, GigOptix holds periodic technology forums and technology audits so that the product development teams of these customers can interact directly with GigOptix’ research and development teams. Likewise, GigOptix’ early involvement in their system development processes also enables GigOptix to influence standards and introduce differentiated products early to market. Moreover, GigOptix believes that this interaction between GigOptix and its customers provides GigOptix a competitive advantage, valuable insight and a close customer relationship that grows over each generation of products introduced by GigOptix’ customers.

Partner for Innovation. Over the past few years, GigOptix has successfully partnered with “Lighthouse” customers, contract manufacturers and U.S. government agencies on research and development in both GigOptix’ electronic components and electro-optics polymer materials. GigOptix sees this as a core element of GigOptix’ strategy both to support the investment required to maintain GigOptix’ innovation as well as aligning GigOptix’ R&D with the future needs of industry and defense markets. In order to maintain GigOptix’ position at the forefront of next generation optical modules and components, GigOptix intends to continue GigOptix’ longstanding relationship with the U.S. government agencies such as the Defense Advanced Research Projects Agency and the Air Force Research Laboratory as well as their network of contractors. GigOptix has aligned with GigOptix’ partners on the long term objectives of research and development related to the integration of semiconductor and thin-film polymer modulators to address tera scale computing and communications for defense and commercial markets and GigOptix has defined multiyear projects to develop and bring these technologies to reality. Similarly, GigOptix partners with leading commercial customers on developments of product required in the one to two years horizon, often sharing the investment. GigOptix believes that this again gives it the assurance of alignment to the market needs when considering the sometimes significant investment in a new development. This model has been used for GigOptix’ 100Gbps modulator drivers for telecom networks, which was launched in 2010. Other cooperative projects include a 100Gbps short reach multi-channel driver and receiver pair with a leading Japanese networking solutions provider, and an innovative ultra low power 10Gbps single channel chipset for a leading enterprise networking solutions provider in China.

Strategic Acquisitions. To augment GigOptix’ organic growth strategy, GigOptix actively pursues acquisitions that provide an efficient alternative to in-house development of technology, products or revenue. The

synergies GigOptix searches for include efficient extension of GigOptix’ product offering to strengthen GigOptix’ market position, enhancing of GigOptix’ technology base, enhancing of GigOptix’ revenue base, and expanding GigOptix’ customer base in selected markets to provide cross selling opportunities or to enhance GigOptix’ geographic or market segment presence. GigOptix continuously evaluates potential acquisitions against the above criteria. GigOptix’ process aims to conduct a swift integration to quickly eliminate duplicate and redundant costs to ensure early accretive performance within one to two quarters. GigOptix’ acquisition of ChipX in 2009 accomplished physical and systems integration, reduced headcount, closed a facility in Haifa, Israel and consolidated its Santa Clara, California personnel into GigOptix’ Palo Alto offices.

GigOptix utilizes proprietary technology at many levels within GigOptix’ product development, ranging from the basic materials research that created the innovative materials GigOptix uses in GigOptix’ TFPS modulators to sophisticated integration and optimization techniques GigOptix uses to design its components. GigOptix is committed to conducting fundamental research in thin-film polymer materials and manufacturing technologies. GigOptix’ technology is protected by GigOptix’ patent portfolio and trade secrets developed in deployments with GigOptix’ extensive customer base. GigOptix’ leading technologies include GigOptix’ fundamental and unique thin-film polymer on silicon technology for optical modulation and extend through ultra broadband MMIC design, MCM design, innovative ultra-low power laser driver and receiver IC design in silicon germanium, high speed analog and RF IC design, mixed signal IC design, and Structured and Hybrid ASIC infrastructure. In particular, the following technologies are central to GigOptix’ business:

High Speed Analog Semiconductor Design & Development. One of GigOptix’ key core competences is circuit design for optimal signal integrity performance in high power applications. GigOptix uses a variety of semiconductor processes to implement GigOptix’ designs including III-V processes such as indium phosphide and gallium arsenide for higher power applications such as long reach telecom transponder. GigOptix also has expertise in low power designs in silicon germanium and CMOS silicon for use in short reach data-com and optical interconnects application and circuit design to reduce cross-talking in dense multi-channel designs.

Electro-Optic TFPS Material. GigOptix’ unique, patent-protected technology is used to lithographically form a Mach-Zehnder modulator using standard silicon production technology processes and GigOptix’ proprietary thin-film polymeric materials. Optical modulators are commonly used as high performance shutters to switch optical signals to apply the digital data to light stream. GigOptix’ technology can support bandwidths of up to 200GHz, while the current generation of material optimized for production is used in 40GHz and 100GHz optical modulators, which are as competitive with leading 40Gbps modulators in the market. The technology has several ground-breaking characteristics as follows: it provides the fastest switching of any available technology and is effectively limited by the bandwidth of the digital control circuit up to 200Gbps bit/second rate; it is suitable for lithographic implementation of an existing semiconductor production line, which facilitates both lower cost manufacturing of on-chip modulators and arrays and close proximity to the digital circuits for optimal performance; and the material operates effectively at very low temperatures, which enables increased frequencies due to the absence of thermally induced noise. All of these unique advantages make the material attractive for telecom, defense and super-computing applications.

GigOptix’ research and development plans are driven by customer and partner input obtained by GigOptix’ sales and marketing teams, through GigOptix’ participation in various standards bodies, and by GigOptix’ long-term technology and product strategies. GigOptix reviews research and development priorities on a regular basis and advise key customers of GigOptix’ progress to achieve better alignment in GigOptix’ product and technology planning. For new components research and development is conducted in close collaboration with GigOptix’ contract manufacturer partners to shorten the time to market and optimize the manufacturability of the products.

GigOptix designs and markets products that amplify electrical signals during both the transmission (drivers) and reception (TIAs) of optical signals as well as modulate optical signals in the transmission of data. GigOptix

has a comprehensive product portfolio for these markets, particularly at data rates that exceed 10Gbps. The primary target market and application for GigOptix’ products are optical interface modules such as line-cards, transponders and transceivers within telecom and data-communications switches and routers. These are critical blocks used in both telecom or data-communications optical communication networks from the long haul to the short reaches where the conversion of data from the electrical domain to the optical domain occurs. GigOptix’ drivers amplify the input digital data stream that is used to modulate laser light either by direct modulation of the laser or by use of an external modulator that acts as a precise shutter to switch on and off light to create the optical data stream. At the other end of the optical fiber, GigOptix’ sensitive receiver TIAs detect and amplify the small currents generated by photo-diodes converting the faint received light into an electrical current. The TIAs amplify the small current signals into a larger voltage signal that can be read by the electronics and processors in the network servers. GigOptix supplies an optimized component for each type of laser, modulator and photo-diode depending upon the speed, reach and required cost. Generally, the shorter the reach is, the higher the volume, the less demanding the product specifications and the greater the pressure to reduce costs. GigOptix implements its products on a number of process technologies and have been at the forefront of extracting optimal performance from each technology to be able to address each market segment’s individual requirements in a cost effective manner. GigOptix’ product portfolio is designed to cover the broad range of solutions needed in these different modules and includes the product lines described below.

1. GX Series: Serial drivers and TIA ICs devices for telecom and data-com markets

2. HX Series: Multi-channel driver and TIA ICs for short reach data-com and optical interconnect applications

3. LX Series: TFPS modulators for high speed telecom and defense applications

4. iT Series: High performance amplifiers for microwave applications in defense and instrumentation

The GigOptix GX Series services both the telecom and data-com markets with a broad portfolio of drivers and transimpedence amplifiers that address 10Gbps, 40Gbps and 100Gbps speeds over distances that range from 100 meters to more than 4000 kilometers.

The HX Series devices are used in proprietary HPC formats, Infiniband, Ethernet and optical HDMI components.

The GigOptix LX Series services the 40Gbps and above telecom market for high performance Mach-Zehnder modulators. The LX Series devices are based on GigOptix’ proprietary TFPS EO material technology. The technology provides what GigOptix believes are significant advantages over competing technologies such as indium phosphide and lithium niobate in areas such as bandwidth, size and power consumption.

GigOptix is now in the process of leveraging GigOptix’ new TFPS technology to enable 40Gbps DQPSK and 100Gbps DP-QPSK devices in market leading small form factors and at the same time leveraging GigOptix’ GX Series of drivers to enable a complete integrated solution set for the customer.

The GigOptix iT Series of products leverages the high performance die and design techniques developed for the GX Series telecom and data-com drivers for related defense and instrumentation applications. GigOptix differentiates itself in the defense and instrumentation markets by providing high gain, broadband devices that exhibit minimal ripple across the gain spectrum of the device: this ensures optimum performance. Moreover, most of GigOptix’ devices have only a single rail supply, which both simplifies the board design and improves reliability of the system. For instance, GigOptix supplies the single rail supply iT2008 high power 26GHz amplifier with a saturated output power of 1W and 1dB of ripple. This device’s performance and ease of use power up sequence has led to extensive use in military radar and satellite communication systems.

The GigOptix CX Series of products offers a broad portfolio of distinct paths to digital and analog mixed signal ASICs with the capability of supporting designs of up to 10M gates in technologies ranging from 0.6µ through 0.13µ. The CX Series uses GigOptix’ proprietary technology in Structured and Hybrid ASICs to enable a generic ASIC solution that can be customized for a customer using only a few metal mask layers. This ensures fast turnaround times with significant cost advantages for customers over both FPGA and dedicated ASIC implementations. The CX Series also offers value added ASIC services including integrating proven Analog and Mixed Signal IP into designs and taking customers designs from RTL or gate-level netlist to volume production with major third party foundries. The CX Series has a significant customer base in the consumer, instrumentation, networking, medical, military and aerospace markets.

The following is a compilation of GigOptix’ product portfolio for optical communications:

GigOptix has a global customer base in the telecommunications, data-communications, defense and industrial electronics markets. GigOptix’ customers include many of the leading network systems vendors supplying worldwide. During 2010 GigOptix sold to major customers including Alcatel-Lucent and other “Tier-One” equipment vendors in the United States, Europe and Asia, as well as leading industrial, aerospace and defense customers.

Of GigOptix’ total revenues in 2010, 25%, 51% and 24% were generated by customers located in Asia, North America and Europe, respectively, compared with 24%, 49% and 27%, respectively, for the year ended December 31, 2009. In 2010, 14% of GigOptix’ revenue was contributed by GigOptix’ government contracts and 86% was contributed by product revenue, compared with 24% and 76%, respectively, for the year ended December 31, 2009.

GigOptix’ customers in the industrial and commercial markets consist of a broad range of companies that design and manufacture electro-optics and high speed information management products. These include medical, industrial, test and measurement, scientific systems, printing engines for high-speed laser printers and defense and aerospace applications. The number of leading network systems vendors which supply the global telecommunications and data communications market is concentrated, and so, in turn, is GigOptix’ customer base. Additionally, Alcatel-Lucent is GigOptix’ largest telecommunications customer, representing 11% and 23% of GigOptix’ total revenues for the years ended December 31, 2010 and December 31, 2009, respectively. Other than Alcatel-Lucent, no other telecommunications customer accounted for more than 10% of total revenues for the years ended December 31, 2010 and December 31, 2009, respectively; however, contracts with the U.S. Government accounted for 14% and 24%, respectively, of our total revenues for the years ended December 31, 2010 and December 31, 2009, respectively.

GigOptix’ foundry and contract manufacturing partners are located in China, Japan, the Philippines, Taiwan, and the United States. Certain of GigOptix’ contract manufacturing partners that assemble or produce modules are strategically located close to GigOptix’ customers’ contract manufacturing facilities to shorten lead times and enhance flexibility.

GigOptix follows established new product introduction processes that ensure product reliability and manufacturability by controlling when new products move from sampling stage to mass production. GigOptix has stringent quality control processes in place for both internal and contract manufacturing. GigOptix utilizes manufacturing planning systems to coordinate procurement and manufacturing to GigOptix’ customers’ forecasts. These processes and systems help GigOptix closely coordinate with GigOptix’ customers, support their purchasing needs and product release plans, and streamline GigOptix’ supply chain.

Electronic components: Integrated circuits and multi-chip modules: For GigOptix’ ICs and MCMs, GigOptix uses an outsourced contract manufacturing model. GigOptix has a prototype manufacturing and testing facility in GigOptix’ Palo Alto location, which is used to optimize manufacturing and test procedures to achieve internal yield and quality requirements before transferring production to GigOptix’ contract manufacturing partners. GigOptix develops long-term relationships with strategic contract manufacturing partners to reduce assembly costs and provide greater manufacturing flexibility. The manufacture of some products such as certain low volume, high complexity or customized multi-chip modules may remain in-house even in mass production to speed time to market and bypass manufacturing transfer costs.

For GigOptix’ less complex packaged chips and bare die products, GigOptix typically moves new product designs directly to contract manufacturing partners. These products fit easily in a standard fabless semiconductor production flow and ramp up to much greater volumes in mass production.

TFPS electro-optic components: Four chemical synthesis labs within GigOptix’ Bothell facility are equipped with chemical hoods capable of delivering EO polymer and claddings in volumes up to kilogram batch volumes. Polymer manufacturing and development are supported by a characterization and test lab equipped with state-of-the-art equipment for measuring molecular and material properties.

Wafer fabrication is supported within the 1,400 square feet class 100 clean-room equipped with standard semiconductor processing. Wafer dicing, cleaning, and facet polishing is supported in the “back end” processing lab outside of the clean-room. GigOptix’ Bothell facility is capable of supporting manufacturing and development of up to five 150mm diameter substrates/week. As volumes increase, GigOptix has identified IMT in Santa Barbara, California as an outsourcing partner with a 30,000 square feet class 100 clean-room dedicated to support contract manufacturing, and IMT is able to support high volume wafer manufacturing. Chip level screening and testing is performed in Bothell using a semi-automated fiber alignment station capable of low frequency testing of insertion loss, Vpi and extinction ratio. EO testing at the chip and package level utilizes RF equipment capable of testing modulators up to 40 GHz. Optical pig-tailing, wire bonding, and sealing are also performed in-house. Samina SCI located in Shenzhen, China has been identified as a source to support volume packaging of up to thousands of units per month.

In the communications market, GigOptix primarily sells its products through its direct sales force supported by a network of manufacturer representatives and distributors. GigOptix’ sales force works closely with GigOptix’ field application engineers, product marketing and sales operations teams in an integrated approach to address a customer’s current and future needs. GigOptix assigns account managers for each strategic customer account to provide a clear interface to GigOptix’ customers, with some account managers responsible for multiple customers. The support provided by GigOptix’ field application engineers is critical in the product qualification stage. Transceiver modules, especially at 10Gbps and above, are complex products that are subject to rigorous qualification procedures of both the product and the supplier and these procedures differ from customer to customer. Also, many customers have custom requirements in addition to those defined by MSAs in order to differentiate their products and meet design constraints. GigOptix’ product marketing teams interface with GigOptix’ customers’ product development staffs to address customization requests, collect market intelligence to define future product development, and represent GigOptix in MSAs.

For GigOptix’ “Lighthouse” customers, GigOptix holds periodic technology forums for their product development teams to interact directly with GigOptix’ research and development teams. These forums provide GigOptix insight into GigOptix’ customers’ longer term needs while helping GigOptix’ customers adjust their plans to the product advances GigOptix can deliver. Also, GigOptix’ customers are increasingly utilizing contract manufacturers while retaining design and key component qualification activities. As this trend matures, GigOptix continually upgrades its sales operations and manufacturing support to maximize GigOptix’ efficiency and flexibility and coordination with GigOptix’ customers.

In the industrial and commercial market, GigOptix primarily sells through a network of manufacturing representatives and distributors to address the broad range of applications and industries in which GigOptix’ products are used. The sales effort is managed by an internal sales team and supported by dedicated field application engineering and product marketing staff. GigOptix also sells direct to certain strategic customers. Through GigOptix’ customer interactions, GigOptix believes that it continually increases its knowledge of each application’s requirements and utilize this information to improve GigOptix’ sales effectiveness and guide product development.

Since inception, GigOptix has actively communicated the GigOptix brand worldwide through participation at trade shows and industry conferences, publication of research papers, bylined articles in trade media, and advertisements in trade publications and interactive media, interactions with industry press and analysts, press releases and GigOptix’ website, as well as through print and electronic sales material.

The market for electronic and electro-optic devices is characterized by price competition, rapid technological change, short product life cycles, and global competition. While no one company competes against GigOptix in all of GigOptix’ product areas, GigOptix’ competitors range from the large, international companies offering a wide range of products to smaller companies specializing in narrow markets. Due to the increasing demands for high-speed, high-frequency components, GigOptix expects competition to increase from existing semiconductor and electro-optical modulator suppliers, in addition to the entry of new competitors to GigOptix’ target markets and from the internal operations of some companies producing products similar to GigOptix’ for their own internal requirements.

Because some of GigOptix’ competitors are large public companies with longer operating histories and greater financial, technical, marketing and other resources, these companies have the ability to devote greater resources to the development, promotion, sale and support of their products. For example, in the telecommunications and data-communications markets, some of GigOptix’ competitors have deeper relationships with prospective customers, related to wider portfolio of products they are selling to them across the board. Other competitors may also have preferential access to certain network systems vendors, or offer directly competitive products that may have better performance measures than GigOptix’ products. Moreover, competitors that have large market capitalizations or cash reserves may be better positioned than GigOptix is to acquire other companies in order to gain new technologies or products that may compete with GigOptix’ product lines. Any of these factors could give GigOptix’ competitors a strategic advantage. Therefore, although GigOptix believes it currently competes favorably with its competitors, GigOptix cannot assure you that it will be able to compete successfully against either current or future competitors in the future.

GigOptix believes the principal competitive factors impacting all of its products are:

In the telecom and data-communications segments, GigOptix competes with Triquint, Rohm, InPhi, Gennum and Vitesse. GigOptix competes with Triquint predominantly in the 10Gbps, 40 Gbps and 100Gbps Mach Zehnder driver space; Rohm predominantly in the 10Gbps EML driver space; InPhi predominately in the TIA spaces and the 40Gbps driver space; Gennum predominately in the data-communications space and Vitesse in the 10Gbps TIA receiver space.

In the market for PMD ICs GigOptix competes with Avago, Emcore, Tyco Electronics (formerly Zarlink) and Iptronics. Avago, Emcore and Tyco Electronics are vertically integrated transceiver module manufacturers

with in-house PMD ICs designs. These companies have comparable products to GigOptix’ products but have been later to market in offering a 10Gbps solutions. In addition to these companies, Iptronics also competes in this space and is a venture-funded startup specializing in parallel optical interconnect with a family of devices at 10Gbps and is a direct competitor.

GigOptix competes with JDSU, Oclaro, Sumitomo and Fujitsu that supply lithium niobate modulators for the long haul/Metro market and more recently JDSU, Sumitomo, Emcore and Oclaro that supply indium phosphide modulators for the Metro market. GigOptix expects that GigOptix’ TFPS modulators will be competitive with lithium niobate and indium phosphide products in terms of pricing and operating performance and will provide significant performance advantages in areas such as size, bandwidth and optical extinction ratio.

GigOptix’ ultra-broadband amplifiers and limiters offer performance with gain flatness and low noise figures. GigOptix competes with Triquint, Hittite, Northrop Grumman (for internal use) and Mimix in this product area.

GigOptix’ ASICs compete in the custom integrated circuit industry, an industry that is intensely competitive. In the low to medium volume market, the primary competitors include Lattice Semiconductor and Actel Corporation. In the medium to high volume market, there are over 30 companies competing in this market. Companies that GigOptix competes with most often include On Semiconductor, eSilicon, Open Silicon, Faraday, Toshiba and eASIC.

GigOptix believes that important competitive factors specific to the custom integrated circuit industry include: Product pricing, time-to-market, product performance, reliability and quality, power consumption, availability and functionality of predefined IP cores, inventory management, access to leading-edge process technology, track record of successful product execution and achieving first time working silicon, ability to provide excellent applications support and customer service, ability to offer a broad range of ASIC solutions to retain existing customers, and compliance with ITAR.

GigOptix relies on patent, trademark, copyright and trade secret laws and internal controls and procedures to protect GigOptix’ technology. GigOptix believes that a robust technology portfolio that is assessed and refreshed periodically is an essential element of GigOptix’ business strategy. GigOptix believes that its success will depend in part on GigOptix’ ability to:

As of December 31, 2010, GigOptix and its subsidiaries have been issued 67 patents and has 9 patent applications pending. Patents have been issued in various countries with the main concentrations in the United States. GigOptix’ patent portfolio covers a broad range of intellectual property including semiconductor design and manufacturing, device packaging, module design and manufacturing, electrical circuit design, thin film polymer technology, modulator design and manufacturing. GigOptix follows well-established procedures for

patenting intellectual property and have internal incentive plans to encourage the protection of new inventions. The portfolio also represents a balanced compilation of intellectual property that has been filed by the various companies GigOptix has acquired, and hence protects all of GigOptix’ product lines. GigOptix also licenses patented technology from the University of Washington. Many of the pending and issued U.S. patents have one or more corresponding internal or foreign patents or applications. GigOptix’ existing significant U.S. patents will expire between August 2021 and November 2028.

GigOptix takes extensive measures to protect GigOptix’ intellectual property rights and information. For example, every employee enters into a confidential information, non-competition and invention assignment agreement with GigOptix when they join and are reminded of their responsibilities when they leave. GigOptix also enters into and enforce a confidential information and invention assignment agreement with contractors.

Although GigOptix believes its patent portfolio is a valuable asset, the discoveries or technologies covered by the patents, patent applications or licenses may not have commercial value. Issued patents may not provide commercially meaningful protection against competitors. Other parties may be able to design around GigOptix’ issued patents or independently develop technology having effects similar or identical to GigOptix’ patented technology. The scope of GigOptix’ patents and patent applications is subject to uncertainty and competitors or other parties may obtain similar patents of uncertain scope. Other parties may discover uses for polymers or technology different from the uses covered in GigOptix’ patents or patent applications and these other uses may be separately patentable. Other parties may have patents covering the composition of polymers for which GigOptix has patents or patent applications covering only methods of use of these polymers.

Third parties may infringe the patents that GigOptix owns or licenses, or claim that GigOptix’ potential products or related technologies infringe their patents. Any patent infringement claims that might be brought by or against GigOptix may cause GigOptix to incur significant expenses, divert the attention of GigOptix’

management and key personnel from other business concerns and, if successfully asserted against GigOptix, require GigOptix to pay substantial damages. In addition, a patent infringement suit against GigOptix could force GigOptix to stop or delay developing, manufacturing or selling potential products that are claimed to infringe a patent covering a third party’s intellectual property.

GigOptix periodically evaluates its patent portfolio based on GigOptix’ assessment of the value of the patents and the cost of maintaining such patents, and may choose from time to time to let various patents lapse, terminate or be sold.

As of December 31, 2010, GigOptix had 83 full-time employees, including 37 in research and development, 27 in operations, 9 in sales and marketing and 10 in general and administrative.

GigOptix has offices in three locations: GigOptix’ headquarters in Palo Alto, California and design centers in Bothell, Washington, and Zurich, Switzerland.

Palo Alto: This location houses the corporate functions and the research and development activities for the GX and CX product lines. It also houses the prototype MCM assembly and test facilities.

Bothell, WA: This is the location of GigOptix’ LX product line. GigOptix’ Bothell, WA site is equipped with facilities to manufacture and develop EO polymer modulators starting at the material level, through wafer fabrication, chip testing, packaging, and final test.

Zurich: This location houses the wholly-owned subsidiary of GigOptix, GigOptix-Helix AG. It is primarily a research and development location with some operations activities to support the HX product line.

GigOptix’ operations involve the use, generation and disposal of hazardous substances and are regulated under international, federal, state and local laws governing health and safety and the environment. GigOptix believes that its products and operations at its facilities comply in all material respects with applicable environmental laws and worker health and safety laws; however, the risk of environmental liabilities cannot be completely eliminated.

From time to time, GigOptix may become involved in legal proceedings, claims and litigation arising in the ordinary course of business. When GigOptix believes a loss is probable and can be reasonably estimated, it accrues the estimated loss in its consolidated financial statements. Where the outcome of these matters is not determinable, GigOptix does not make a provision in its financial statements until the loss, if any, is probable and

can be reasonable estimated or the outcome becomes known. GigOptix believes that there are currently no claims or legal actions that would, in management’s judgment based on information currently available, have a material adverse effect on GigOptix’ results of operations, financial condition or cash flows.

In or about November 2008, an entity named DBSI Inc., which at the time was the beneficial owner of membership units in a predecessor of GigOptix, filed for bankruptcy in the United States Bankruptcy Court for the District of Delaware (Case No. 08-12687 (PJW)). In December 2008, in connection with the merger of such predecessor, Lumera Corporation and GigOptix, the membership units converted into 1,715,161 shares of GigOptix’ common stock and GigOptix issued warrants to purchase 660,473 shares of common stock at a weighted average exercise price of $32.35 per share with a range of exercise periods that expire between December 31, 2011 and April 23, 2017. The DBSI Liquidating Trust subsequently became the holder of the 1,715,161 shares of common stock and the warrants to purchase 660,473 shares of common stock. GigOptix understands that an affiliate of the DBSI Liquidating Trust, the DBSI Estate Litigation Trust, has been evaluating various potential claims which it might assert against a number of entities, including GigOptix and certain affiliated parties. GigOptix’ management engaged in discussions with the trustee regarding whether the DBSI Estate Litigation Trust has any claims against GigOptix. GigOptix disputed the existence of any such claims, and intended to vigorously defend any claims made.

On April 8, 2011, GigOptix and the trustees for the DBSI Estate Litigation Trust and the DBSI Liquidating Trust reached the following agreement. As full settlement of all potential claims, the DBSI Liquidating Trust surrendered to GigOptix for cancellation all of the existing warrants to purchase 660,473 shares of GigOptix’ common stock and GigOptix in exchange issued to the DBSI Liquidating Trust two warrants which will not be exercisable for a period of six months from the date of issuance; one warrant for 500,000 shares of common stock, which will have a term of three years and an exercise price of $2.60 per share, and the other warrant, also for 500,000 shares of common stock, which will have a term of four years and an exercise price of $3.00 per share. GigOptix filed an amendment to the registration statement filed on Form S-1 on March 28, 2011 for the purpose of including the registration of the shares of common stock underlying the warrants in such registration statement. As further consideration for the issuance of the warrants, the DBSI Estate Litigation Trust and the DBSI Liquidating Trust have given GigOptix a full release of all known and unknown claims which each of them may have, and acknowledge that GigOptix disclaims all liability.

GigOptix is subject to federal, state and local laws and regulations relating to the generation, handling, treatment, storage and disposal of certain toxic or hazardous materials and waste products that GigOptix uses or generates in its operations.

Pursuant to the terms of the merger agreement to acquire Endwave, Mr. Mikulsky and Mr. Lazzara will be appointed to the GigOptix board of directors at the closing of the merger.

There are no immediate family relationships between or among any of GigOptix’ executive officers and directors.

GigOptix’ board of directors has determined that Mr. Judson, Mr. Miotto, Mr. Schneider and Ms. Trapp are “independent” directors.

GigOptix uses the independence standards set forth by Rule 5605(a)(2) of the Nasdaq Listing Rules. In reviewing the independence of its directors against these standards, GigOptix considers relationships and transactions between each director and members of the director’s family with GigOptix and its affiliates. Each member of GigOptix’ two standing committees of its board of directors, the Audit Committee and the Compensation Committee, is independent as defined by Rule 5605(a)(2) of the Nasdaq Listing Rules, and each member of GigOptix’ Audit Committee is also independent as defined by Rule 10A-3(b)(1) under the Exchange Act. GigOptix does not have a separately designated Nominating Committee. Directors are nominated by the independent directors of the board of directors.

The table below sets forth the compensation earned by GigOptix’ Chief Executive Officer and its two other most highly compensated executive officers for the fiscal years ended December 31, 2010 and 2009 whose compensation exceeded $100,000. These individuals are collectively referred to as GigOptix’ named executive officers.

The Summary Compensation Table sets forth the aggregate compensation earned by each of GigOptix’ named executive officers in 2010 and 2009.

The components of executive compensation consist of salary, annual cash bonuses and equity grants. Annual cash bonuses are awarded in the discretion of the Compensation Committee of the board of directors after a review and evaluation of each executive officer’s performance during the year. Equity grants generally consist of stock options, but in the past warrants have also been issued, and are intended to serve as long-term compensation. The Compensation Committee may also authorize special compensation awards in the form of cash or equity grants to recognize extraordinary efforts or results.

Equity awards are generally granted pursuant to the GigOptix, Inc. 2008 Equity Incentive Plan. Equity grants to GigOptix’ executive officers generally vest as to 25% of the underlying award on the one-year anniversary of the grant date and monthly thereafter for a period of three years. However, certain equity awards to GigOptix’ executive officers vest in accordance with certain performance goals being achieved, as discussed in more detail below in the vesting schedules for such equity awards. In the case of stock options and warrants, the exercise price is set at 100% of the fair market value of the underlying common stock on the date of grant.

GigOptix has entered into a standard employment agreement with each of GigOptix’ executive officers, which governs the standard terms of employment as well as provides for certain payments upon termination of employment. GigOptix has entered into an employment agreement with Dr. Avi Katz, GigOptix’ Chief Executive Officer, for the same purpose but with different terms. Both Dr. Katz’s employment agreement and the standard employment agreement are discussed in more detail below under the caption “Employment Arrangements with Named Executive Officers.”

GigOptix does not have deferred compensation plans, pension plans or other similar arrangements or plans for GigOptix’ executive officers, except a tax-qualified 401(k) Plan, which is available generally to all of GigOptix’ employees.

On February 3, 2011, GigOptix entered into a new employment agreement with Dr. Katz, GigOptix’ Chief Executive Officer. The term of the agreement is through December 31, 2014, and it establishes his annual salary, bonuses and eligibility for health benefits, among other provisions. The agreement also provides for severance payments under certain circumstances. In the event that he terminates his employment by reason of death or disability, Dr. Katz (or his estate) is entitled to his annual bonus (pro rata based on amount of time employed), six months of continued salary and continued health benefits (or the cash value in the case of death). If Dr. Katz is terminated without cause (as defined in the agreement) or terminates his employment for good reason (as defined in the agreement), he is entitled to his annual bonus (pro rata based on amount of time employed), six months of continued salary, a lump sum equal to 18 months of his salary, vesting of 75% of his outstanding unvested equity awards and continued health benefits. In the event of termination in connection with a change in control (as defined in the agreement), Dr. Katz is be entitled to his annual bonus (pro rata based on amount of time employed), three years of his annual salary and bonus, vesting of all of his outstanding unvested equity awards and continued health benefits.

GigOptix has entered into a standard employment agreement with all of GigOptix’ other executive officers. The standard employment agreement sets forth certain provisions regarding annual salary, bonuses and eligibility

for health benefits among other provision. According to the terms of the agreement, if the executive officer’s employment terminates because of death or disability, he (or his estate) is entitled to his annual bonus (pro rata based on amount of time employed), six months of continued salary and continued health benefits (or the cash value in the case of death). In the event of termination by us for reasons other than cause (as defined in the agreement) or termination by the executive officer for good reason (as defined in the agreement), the executive officer is entitled to his annual bonus (pro rata based on amount of time employed), six months of continued salary, vesting of 25% of the executive officer’s outstanding unvested equity awards and continued health benefits. The standard employment agreement has no special provisions for terminations in connection with a change in control.

The GigOptix, Inc. 2008 Equity Incentive Plan contains certain provisions for change in control transactions. In the event of a Covered Transaction (as defined in the plan), the outstanding awards must either be assumed or substituted by the successor company or will be fully accelerated prior to the closing of the Covered Transaction.

The following table sets forth the compensation earned for services performed for GigOptix as a director by each member of GigOptix’ board of directors, other than any directors who are also GigOptix’ named executive officers, during the fiscal year ended December 31, 2010.

As a result of the acquisition of ChipX on November 9, 2009, National Instruments Corporation, a former stockholder of ChipX, currently holds 1,066,265 shares of GigOptix’ common stock or 8.7% of GigOptix’ common stock. GigOptix generated revenue of $1.6 million and $231,000 from sales to National Instruments Corporation during the years ended December 31, 2010 and 2009, respectively.

GIGOPTIX’ MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

You should read the following discussion and analysis in conjunction with GigOptix’ consolidated financial statements and the related notes included elsewhere in this proxy statement/prospectus. This discussion and analysis contains forward-looking statements that involve risks, uncertainties, and assumptions. GigOptix’ actual results may differ materially from those anticipated in these forward-looking statements as a result of certain factors, including, but not limited to, those set forth under “Risk Factors” beginning on page 19 of this proxy statement/prospectus and GigOptix’ consolidated financial statements and related notes appearing elsewhere in this proxy statement/prospectus. GigOptix assumes no obligation to update the forward-looking statements or such risk factors. Please see “Special Cautionary Note Regarding Forward-Looking Statements” on page 49 of this proxy statement/prospectus.

GigOptix is a leading supplier of electronic and electro-optical components that enable high-speed telecommunications and data-communications networks globally. GigOptix’ strategy is to apply GigOptix’ core technical expertise in optical, electro-optical and high speed analog technology to develop products that address high growth product and market opportunities.

The following sets forth GigOptix’ significant corporate and product milestones:

GigOptix focuses on the specification, design, development and sale of analog semiconductor ICs, MCMs, polymer modulators, and analog and mixed signal custom ASICs. GigOptix believes that it is an industry leader in the fast growing market for electronic solutions that enable high-bandwidth optical connections found in telecom systems, data-com and storage systems, and, increasingly, in CE and computing systems.

These products are capable of performing in various applications, demanding a wide range of data processing speeds, from consumer electronics, which perform at data processing speeds of 3Gbps to 10Gbps, to sophisticated ultra-long haul submarine telecommunications systems, which require performance at data processing speeds from 10Gbps and 40Gbps to 100Gbps.

GigOptix’ fiscal year ends on December 31. The consolidated financial statements include GigOptix’ accounts and GigOptix’ wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.

GigOptix markets and sells GigOptix’ products in North America, Asia and Europe and other locations through GigOptix’ direct sales force, distributors and sales representatives. The percentage of GigOptix’ revenue generated from shipments outside North America was approximately 49% and 51% in fiscal 2010 and fiscal 2009, respectively. GigOptix measures sales location by the shipping destination, even if the customer is headquartered in the U.S. GigOptix anticipates that sales to international customers will continue to represent a significant percentage of GigOptix’ revenue. The percentages of GigOptix’ revenue by region are set forth in the following table:

Customer purchase orders are generally used to establish terms of sales. Because industry practice allows customers to reschedule or cancel orders on relatively short notice, backlog may not be a good indicator of GigOptix’ future sales. Cancellations of customer orders or changes in product specifications could result in the loss of anticipated sales without allowing GigOptix sufficient time to reduce its inventory and operating expenses.

Since a significant portion of GigOptix’ revenue is from the digital consumer electronics market, GigOptix’ business may be subject to seasonality, with increased revenues in the third and fourth calendar quarters of each year, when customers place orders to meet year-end holiday demand. However, due to the complex nature of the markets GigOptix serves and the broad fluctuations in economic conditions in the U.S. and other countries, it is difficult for GigOptix to assess the impact of seasonal factors on GigOptix’ business.

GigOptix is subject to the risks of conducting business internationally, including economic conditions in Asia, particularly Taiwan and China, changes in trade policy and regulatory requirements, duties, tariffs and other trade barriers and restrictions, the burdens of complying with foreign laws and, possibly, political instability. Most of GigOptix’ foundries and all of GigOptix’ assembly and test subcontractors are located in Asia. Although GigOptix’ international sales are largely denominated in U.S. dollars, GigOptix also enters into sales transactions in New Taiwan dollars, in Hong Kong dollars and in Chinese renminbi. In addition, GigOptix has foreign operations where expenses are generally denominated in the local currency. Such transactions expose GigOptix to the risk of exchange rate fluctuations. GigOptix monitors its exposure to foreign currency fluctuations, but has not adopted any hedging strategies to date. There can be no assurance that exchange rate fluctuations will not harm GigOptix’ business and operating results in the future.

Due to the continued uncertain economic conditions, GigOptix’ current or potential customers may delay or reduce purchases of GigOptix’ products, which would adversely affect GigOptix’ revenues and harm GigOptix’ business and financial results. GigOptix expects its business to be adversely impacted by any future downturn in the U.S. or global economies. In the past, industry downturns have resulted in reduced demand and declining average selling prices for GigOptix’ products which adversely affected GigOptix’ business. GigOptix expects to continue to experience these adverse business conditions in the event of further downturns.

Management’s Discussion and Analysis of Financial Condition and Results of Operations discusses GigOptix’ consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, management evaluates its estimates and judgments, including those related to product returns, bad debts, inventories, asset impairments, deferred tax assets, accrued warranty reserves, restructuring costs, contingencies and litigation. Management bases its estimates and judgments on historical experience and on various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Management believes the following critical accounting policies, among others, affect GigOptix’ more significant judgments and estimates used in the preparation of GigOptix’ consolidated financial statements.

An accounting policy is deemed to be critical if it requires an accounting estimate to be made based on assumptions about matters that are highly uncertain at the time the estimate is made, and if different estimates that reasonably could have been used or changes in the accounting estimate that are reasonably likely to occur could materially change the financial statements. GigOptix also has other key accounting policies that are less subjective, and, therefore, their application would not have a material impact on GigOptix’ reported results of operations. The following is a discussion of GigOptix’ critical accounting policies, as well as the estimates and judgments involved.

Revenue from sales of optical modulator drivers and receivers, MCMs, and other products is recognized when persuasive evidence of a sales arrangement exists, transfer of title occurs, the sales price is fixed or determinable and collection of the resulting receivable is reasonably assured. Revenue for product shipments is recognized upon shipment of the product to the customer. Provisions are made for warranties at the time revenue is recorded.

Customer purchase orders are generally used to determine the existence of an arrangement. Transfer of title and risk of ownership occur based on defined terms in customer purchase orders, and generally pass to the customer upon shipment, at which point goods are delivered to a carrier. There are no formal customer acceptance terms or further obligations, outside of GigOptix’ standard product warranty. GigOptix assesses whether the sales price is fixed or determinable based on the payment terms associated with the transaction. Collectability is assessed based primarily on the credit worthiness of the customer as determined through ongoing credit evaluations of the customer’s financial condition, as well as consideration of the customer’s payment history.

Revenue generated from engineering product development projects and research and development cost reimbursement contracts, cost plus fixed fee type contracts, for the United States government is recorded in

accordance with accounting guidance for contract accounting, using the percentage of completion method measured on a cost-incurred basis. Changes in contract performance, contract conditions, and estimated profitability, including those arising from contract penalty provisions and final contract settlements, may result in revisions to costs and revenues and are recognized in the period in which the revisions are determined. In the quarter ended December 31, 2009, GigOptix recorded a reserve of $1.3 million associated with a change in estimated rates under which GigOptix could bill for the work GigOptix performed under various government contracts during fiscal 2009. Profit incentives are included in revenue when realization is assured. Losses, if any, are recognized in full as soon as identified. Losses occur when the estimated direct and indirect costs to complete the contract exceed the unrecognized revenue on the contract. GigOptix evaluates the reserve for contract losses on a contract-by-contract basis. No losses have been incurred on any contracts to date.

GigOptix estimates contract costs based on the experience of its professional researchers, the experience GigOptix has obtained in internal research efforts, and GigOptix’ performance on previous contracts. GigOptix believes this allows it to reasonably estimate the tasks required and the contract costs; however, there are uncertainties in estimating these costs, such as the ability to identify precisely the underlying technical issues hindering development of the technology; the ability to predict all the technical factors that may affect successful completion of the proposed tasks; and the ability to retain researchers having enough experience to complete the proposed tasks in a timely manner. Should actual costs differ materially from GigOptix’ estimates, GigOptix may have to adjust the timing and amount of revenue it recognizes. To date, GigOptix has mitigated the risk of failing to perform under these contracts by negotiating best efforts provisions, which do not obligate GigOptix to complete contract deliverables.

Inventories are stated at the lower of cost or market value, with cost computed on an average-cost basis. Cost includes labor, material and overhead costs, including product and process technology costs. Determining fair market value of inventories involves numerous judgments, including projecting average selling prices and sales volumes for future periods and costs to complete products in work in process inventories. As a result of this analysis, when fair market values are below GigOptix’ costs, GigOptix records a charge to cost of revenue in advance of when the inventory is scrapped or sold.

GigOptix evaluates its ending inventories for excess quantities and obsolescence on a quarterly basis. This evaluation includes analysis of historical and forecasted sales quantities by product. Inventories on hand in excess of forecasted demand are written down. In addition, GigOptix writes off inventories that are considered obsolete. Obsolescence is determined from several factors, including competitiveness of product offerings, market conditions and product life cycles when determining obsolescence. Increases to the provision for excess and obsolete inventory are charged to cost of revenue. At the point of the loss recognition, a new, lower-cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. If this lower-cost inventory is subsequently sold, the related provision is matched to the movement of related product inventory, resulting in lower costs and higher gross margins for those products.

GigOptix’ inventories include high-technology parts that may be subject to rapid technological obsolescence and which are sold in a highly competitive industry. If actual product demand or selling prices are less favorable than GigOptix’ estimates, it may be required to take additional inventory write-downs.

recoverable, GigOptix tests for recoverability based on an estimate of undiscounted cash flows as compared to the asset’s carrying amount. If the carrying value exceeds the estimated future cash flows, the asset is considered to be impaired. The amount of impairment is measured as the difference between the carrying amount and the fair value of the impaired asset. Factors GigOptix considers important that could trigger an impairment review include continued operating losses, significant negative industry trends, significant underutilization of the assets and significant changes in the way GigOptix plans to use the assets.

The estimation of future cash flows involves numerous assumptions, which require GigOptix’ judgment, including, but not limited to, future use of the assets for GigOptix’ operations versus sale or disposal of the assets, future-selling prices for GigOptix’ products and future production and sales volumes. In addition, GigOptix must use its judgment in determining the groups of assets for which impairment tests are separately performed.

Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business combination and is not subject to amortization. GigOptix evaluates goodwill for impairment on an annual basis or whenever events and changes in circumstances suggest that the carrying amount may not be recoverable. Impairment of goodwill is tested at the reporting unit level by comparing the reporting unit’s carrying amount, including goodwill, to the fair value of the reporting unit. GigOptix operates in one reporting unit.

As part of the process of preparing GigOptix’ consolidated financial statements, GigOptix is required to estimate GigOptix’ income taxes in each of the jurisdictions in which it operates. This process involves estimating GigOptix’ current tax exposure and assessing temporary differences resulting from differing treatment of items, such as deferred revenues, for tax and accounting purposes. These differences result in deferred tax assets and liabilities. GigOptix then assess the likelihood that GigOptix’ deferred tax assets will be recovered from future taxable income and to the extent GigOptix establishes a valuation allowance or increase this allowance in a period, GigOptix will include an additional tax provision in GigOptix’ consolidated statement of operations.

In June 2006, the Financial Accounting Standards Board, or FASB, issued accounting guidance which provides for a two-step approach to recognize and measure uncertain tax positions. GigOptix considers many factors when evaluating and estimating GigOptix’ tax positions and tax benefits, which may require periodic adjustments and which may not accurately anticipate actual outcomes. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. Whether the more-likely-than-not recognition threshold is met for a tax position is a matter of judgment based on the individual facts and circumstances of that position evaluated in light of all available evidence.

Stock-based compensation is measured at the date of grant, based on the fair value of the award. GigOptix amortizes the compensation costs on a straight-line basis over the requisite service period of the option, which is generally the option vesting term of four years. The benefits of tax deductions in excess of recognized compensation expense must be reported as a financing cash flow, rather than as an operating cash flow. This may reduce future net cash flows from operations and increase future net financing cash flows.

GigOptix estimates the fair value of stock options granted using a Black-Scholes option-pricing model. This model requires the input of highly subjective assumptions, along with certain policy elections, including the options’ expected life and the price volatility of GigOptix’ underlying stock options. Actual volatility, expected lives, interest rates and forfeitures may be different from GigOptix’ assumptions, which would result in an actual value of the options being different from estimated. This fair value of stock option grants is amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period.

From time to time GigOptix also issues stock option grants to directors and employees that have a market condition. In such cases stock options will vest only if the average price of our stock is at or exceeds a certain price threshold during a specific, previously defined period of time. To the extent that the market condition is not met, the options do not vest and are cancelled. In these cases, GigOptix cannot use the Black-Scholes model; GigOptix must use a Monte Carlo simulation. GigOptix engages a third party valuation firm to support management’s valuation of these options using Monte Carlo simulation techniques that incorporate assumptions as provided by management for the expected holding period, risk-free interest rate, stock price volatility and dividend yield. Compensation expense is recognized until such time as the market condition is either met or not met. Certain stock options granted on March 17, 2010 were classified as option grants having a market condition.

GigOptix also issues stock options which have company specific financial performance criteria. In this case, GigOptix makes a determination regarding the probability of the performance criteria being achieved and use a Black-Scholes model to value the options incorporating assumptions as provided by management for the expected holding period, risk-free interest rate, stock price volatility and dividend yield. Compensation expense is recognized until such time as the performance criteria is met or not met. Certain stock options granted on October 27, 2010 were classified as option grants having a performance condition.

Expected Term—GigOptix’ expected term used in the Black-Scholes valuation method represents the period that GigOptix’ stock options are expected to be outstanding and is derived from the historical expected terms of “guideline” companies selected based on similar industry and product focus.

Expected Volatility—GigOptix’ expected volatility used in the Black-Scholes valuation method is derived from a combination of historical and implied volatility of “guideline” companies selected based on similar industry and product focus.

Expected Dividend—GigOptix has never paid dividends and currently do not intend to do so, and accordingly, the dividend yield percentage is zero for all periods.

Risk-Free Interest Rate—GigOptix bases the risk-free interest rate used in the Black-Scholes valuation method on the implied yield currently available on U.S. Treasury constant maturities issued with a term equivalent to the expected term of the option.

GigOptix makes an estimate of expected forfeitures and recognizes compensation costs only for those equity awards expected to vest. When estimating forfeitures, GigOptix considers voluntary termination behavior as well as an analysis of actual option forfeitures.

In April 2010, the FASB updated its guidance related to the milestone method of revenue recognition. The update provides guidance on the criteria that should be met for determining whether the milestone method of revenue recognition is appropriate. A vendor can recognize consideration that is contingent upon achievement of a milestone in its entirety as revenue in the period in which the milestone is achieved only if the milestone meets all criteria to be considered substantive. The updated guidance became effective on a prospective basis for milestones achieved in fiscal years, and interim periods within those years beginning on or after June 15, 2010, with early adoption permitted. We do not expect adoption to have a material impact on our consolidated results of operations or financial condition.

In July 2010, the FASB issued new standards which amend the receivable disclosure requirements, including the credit quality of financing receivables and the allowance for credit losses. These standards require additional disclosures that will facilitate financial statement user’s evaluation of the nature of credit risk inherent in financing receivables, how that risk is analyzed in arriving at the allowance for credit losses, and the reason for any changes in the allowance for credit losses. These new standards are required to be adopted for interim and annual reporting periods beginning on or after December 15, 2010. The adoption of these standards will not have a material impact on our consolidated financial statements.

In December 2010, the FASB updated its guidance related to when to perform step two of the goodwill impairment test for reporting units with zero or negative carrying amounts. The updated guidance requires that for any reporting unit with a zero or negative carrying amount, and entity is required to perform Step 2 of the goodwill impairment test if it is more likely than not that a goodwill impairment exists. In determining whether it is more likely than not that a goodwill impairment exists, an entity should consider whether there are any adverse qualitative factors indicating that an impairment may exist. The updated guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2010. We do not expect adoption to have a material impact on our consolidated results of operations or financial condition.

In December 2010, the FASB updated its guidance related to disclosure of supplementary pro forma information for business combinations. The updated guidance requires that if comparative financial statements are presented, the pro forma revenue and earnings of the combined entity for the comparable prior reporting period should be reported as though the acquisition date for all business combinations that occurred during the current year had been as of the beginning of the comparable prior annual reporting period only. The updated guidance is effective prospectively for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2010, with early adoption permitted. We will adopt the updated guidance and we do not expect adoption to have an impact on our consolidated results of operations or financial condition as the updated guidance only affects disclosures related to future business combinations.

The following table sets forth GigOptix’ consolidated results of operations for the fiscal years ended December 31, 2010 and December 31, 2009, and the year-over-year increase (decrease) in GigOptix’ results, expressed both in dollar amounts (thousands) and as a percentage of total revenues, except where indicated:

Revenue for the periods reported was as follows (in thousands, except percentages):

Revenue for the year ended December 31, 2010 was $26.9 million, an increase of $12.1 million or 81% compared with $14.8 million for the year ended December 31, 2009. Revenue increased in 2010 primarily due to sales of products related to our acquisition of ChipX in November 2009, as well as an 8% increase in revenue related to contracts with the U.S. Government. Government contract revenue was reduced in 2009 due to a change in estimated billing rates.

Gross profit consists of revenue, less cost of revenue, which includes amortization of certain identified intangible assets. Cost of revenue consists primarily of the costs to manufacture saleable chips, including outsourced wafer fabrication and testing. Amortization expense of identified intangible assets, namely existing technology, is also presented within cost of revenue, as the intangible assets were determined to be directly attributable to revenue generating activities.

Cost of revenue and gross profit for the periods presented were as follows (in thousands, except percentages):

Gross profit for the year ended December 31, 2010 was $14.3 million, or 53% of revenue, an increase of $7.6 million or 114% as compared to a gross profit of $6.7 million, or 45% of revenue, for the year ended December 31, 2009. The increase in gross profit in 2010 from 2009 resulted primarily from a full year of revenue resulting from products acquired from ChipX in November 2009, increased gross profit related to billings on contracts to the U.S. government and a reduction in intangible amortization classified as cost of revenue. Gross profit in 2009 was reduced due to a change in estimated billing rates on government contracts. Gross profit on contracts with the U.S. Government increased in 2010 compared to 2009 as GigOptix began to charge only those direct costs related to government contracts to cost of revenue.

Research and development expenses are expensed as incurred. Research and development costs consist primarily of employee compensation, consulting and engineering design, non-capitalized tools and equipment and equipment depreciation.

Research and development expense for the periods presented was as follows (in thousands, except percentages):

Research and development expense for the year ended December 31, 2010 was $8.7 million compared to $6.3 million for the year ended December 31, 2009, an increase of $2.4 million or 38%. The increase in research and development expense primarily resulted from an increase in payroll of $1.9 million, an increase in stock-based compensation of $0.3 million, and increased expense related to outside services of $0.2 million.

Selling, general and administrative expenses consist primarily of salaries and benefits for management, marketing and administration personnel, as well as fees for consultants supporting the sales, marketing and administrative functions.

Selling, general and administrative expense for the periods presented was as follows (in thousands, except percentages):

Selling, general and administrative expense for the year ended December 31, 2010 was $8.9 million compared to $9.9 million for the year ended December 31, 2009, a decrease of $1.0 million or (10)%. This decrease is primarily due to reduced professional fees, including legal, accounting and auditing services of $1.4 million, a decrease in facility costs of $0.2 million, a decrease in the amortization of employment escrow of $0.1 million, and a decrease in investor relations costs of $0.1 million, offset by increases in payroll expense, including stock-based compensation, of $0.8 million.

In the first quarter of 2010, GigOptix decided to close its R&D design center in Haifa, Israel which was acquired as part of the merger with ChipX in 2009. GigOptix took a restructuring charge of $388,000 to account for employee severance of $156,000, future facility rent expense of $61,000 for the remainder of the lease term

through the end of fiscal 2010, a write-down of fixed assets of $121,000, and accounting and legal expenses of $50,000. At December 31, 2010, GigOptix’ remaining accrued restructuring liability relating to closing the design center in Israel was $34,000.

In December 2009, GigOptix adopted a plan to reduce the size of GigOptix’ facilities in Bothell, Washington, from approximately 32,000 square feet to approximately 12,000 square feet and took a restructuring charge of $424,000 to reflect the proportionate share of remaining lease expense GigOptix will incur for the unoccupied space of the facility and costs associated with improvements needed to segregate the facility. Of this amount, $396,000 was paid out in 2010 and the remaining $28,000 balance will be paid in 2011. The existing lease on the facility expires in 2014. Although GigOptix made available for sublease approximately 20,000 square feet, it did not receive any sublease income associated with this space prior to expiration of the reduction in space, which occurred in February 2011.

In October 2009, in anticipation of its acquisition by GigOptix, ChipX incurred severance costs of $0.4 million in connection with a reduction in its work force. GigOptix recognized this expense in GigOptix’ consolidated statement of operations after the acquisition date as a restructuring expense. All amounts were paid in 2009.

Other expense, net and interest expense, net for the periods presented were as follows (in thousands, except percentages):

Interest expense, net for the year ended December 31, 2010 increased by $0.4 million primarily due to interest expense associated with GigOptix’ line of credit and term loan with Silicon Valley Bank, interest incurred on loans with Bridge Bank and Agility Capital during the first two quarters of fiscal 2010 and interest incurred on a capital lease for engineering design software. Other income of $0.3 million in 2009 changed by $0.6 million in 2010 to a recognized expense of $0.3 million. The expense recognized during 2010 was due primarily to the change in fair value related to warrants accounted for under liability accounting. The $0.3 million of income recognized in 2009 was primarily related to the sale of the assets of GigOptix’ Plexera Bioscience LLC subsidiary, including all patents and trademarks related to the Plexera business, on February 17, 2009. The assets were sold “as is” to Plexera, LLC, a newly formed company, for $0.3 million and GigOptix recorded a gain of $0.3 million. GigOptix does not expect to receive any further consideration from the sale of the Plexera assets.

Provision for income taxes was approximately $51,000 in the year ended December 31, 2010, and the benefit from income taxes was $69,000 in the year ended December 31, 2009. The effective tax rate was (1.18)% and 0.68% for the years ended December 31, 2010 and 2009, respectively. Income taxes during 2010 primarily relate to ASC740 reserves and state tax true ups. Income taxes during 2009 relate primarily to the amortization of a deferred tax liability, established upon the acquisition of GigOptix’ Swiss subsidiary in 2008, partially offset by current taxes payable related to a foreign subsidiary.

Cash and cash equivalents and cash flow data for the periods presented were as follows (in thousands):

In April 2010, GigOptix entered into a loan and security agreement with Silicon Valley Bank. Pursuant to the loan and security agreement, GigOptix is entitled to borrow from Silicon Valley Bank up to $3.0 million, based on net eligible accounts receivable after an 80% advance rate and subject to limits based on GigOptix’ eligible accounts as determined by Silicon Valley Bank. Interest on extensions of credit under this revolving loan is equal to the prime rate of Silicon Valley Bank, which at December 31, 2010 was 4.0% per annum, plus 1.5% per annum, or the applicable rate. In addition, a monthly collateral handling fee of 0.30% per each gross financed account receivable shall apply, or the collateral handling fee. If GigOptix achieves certain quarterly financial performance targets as stated in the loan and security agreement, the applicable rate and the collateral handling fee shall be reduced to the prime rate of Silicon Valley Bank plus 1.0% per annum and 0.20%, respectively. This revolving loan was used by GigOptix to replace its revolving accounts receivable credit line with Bridge Bank. With the initial funding by Silicon Valley Bank of the revolving loan, GigOptix terminated its loan and security agreement with Bridge Bank, which is discussed below, as having been fully performed by GigOptix. The loan and security agreement also contains events of default customary for credit facilities of this type, including, among other things, nonpayment of principal or interest when due. The loan and security agreement will expire on April 23, 2012. The amount outstanding on GigOptix’ line of credit on December 31, 2010 was $3.0 million.

Pursuant to the loan and security agreement, Silicon Valley Bank is making available a term loan in an amount up to $400,000, subject to the satisfaction of terms and conditions of the loan and security agreement, which can be drawn down one time for the purpose of refinancing GigOptix’ outstanding obligations to Agility Capital. The term loan is repayable in eighteen equal monthly installments and interest is fixed at a rate per annum of 9.0%. GigOptix used the proceeds of the term loan to pay off its loan and terminate its loan agreement with Agility Capital. The amount outstanding on the term loan on December 31, 2010 was $0.2 million. The weighted average interest rate on GigOptix’ loans outstanding on December 31, 2010 is 5.7%.

The loan and security agreement with Silicon Valley Bank is secured by all of GigOptix’ assets, including all accounts, equipment, inventory, receivables and intangibles. The loan and security agreement contains certain restrictive covenants that will impose significant operating and financial restrictions on GigOptix’ operations, including, but not limited to:

The receipt of Silicon Valley Bank’s prior written approval of the proposed merger with Endwave is a condition to Endwave’s obligation to effect the closing of the merger.

In connection with the loan and security agreement, GigOptix granted Silicon Valley Bank (i) a warrant to purchase 125,000 shares of GigOptix’ common stock at an exercise price equal to $4.00 per share, or the Warrant, and (ii) a warrant to purchase a second tranche of up to 100,000 shares of GigOptix’ common stock which shall vest 15,000 shares per month incrementally beginning September 1, 2010 (although the last monthly incremental vesting amount shall be 10,000 shares) at an exercise price equal to the closing market price on each date of vesting, or the Second Tranche Warrant. In the event that either GigOptix closes an equity investment of at least $4.0 million or it has been EBITDA positive for the preceding three months, then vesting shall cease, and all unvested shares under the Second Tranche Warrant shall lapse. In July 2010, GigOptix satisfied the requirements of closing an equity investment of at least $4.0 million and the Second Tranche Warrant expired. The Warrant includes anti-dilution provisions and “piggy-back” registration rights permitting registration in a future public offering by GigOptix. The shares underlying the Warrant were registered on a Registration Statement on Form S-1 that was declared effective by the Securities and Exchange Commission on July 2, 2010. The Warrant may either be (i) converted, on a cashless, net settlement basis, based on the fair market value as determined pursuant to the terms of the Warrant, or (ii) exercised by delivering a duly executed notice of exercise. The Warrant has a term of seven years; the fair value of the Warrant has been determined using a Black-Scholes option pricing model. The full fair value of the warrant has been classified as a non-current asset and as equity on the balance sheet and is being amortized over two years. GigOptix has recorded interest expense of $0.1 million during fiscal 2010 related to these warrants. The balance of the asset is $0.2 million as of December 31, 2010.

In November 2009, GigOptix entered into a loan and security agreement with Bridge Bank under which it could borrow up to $4.0 million, based on net eligible accounts receivable. Borrowings under the line of credit bore interest at the bank’s prime rate plus 2.50% (6.50% as of December 31, 2009), provided that in no event would the prime rate be less than 4.0%. Borrowings under the line were collateralized by a security interest in all of GigOptix’ assets. On April 28, 2010, GigOptix paid Bridge Bank approximately $1.6 million to fully repay GigOptix’ liabilities covering principal, accrued interest and various fees related to GigOptix’ line of credit. At this time the loan and security agreement with Bridge Bank was cancelled. At December 31, 2009 GigOptix had an outstanding balance on GigOptix’ line of credit of approximately $1.5 million which was offset by a loan discount of $152,000.

On January 29, 2010, GigOptix entered into a loan agreement for a secured line of credit facility with Agility Capital, LLC, or Agility Capital, to pay for transaction expenses incurred by GigOptix in GigOptix’ acquisition of ChipX. The secured credit facility provided that GigOptix may borrow one advance of up to $500,000 and had a maturity date of December 1, 2010. Borrowings incurred interest at 14.0% per annum. Beginning March 1, 2010, and on the first day of each month thereafter, $50,000 plus accrued but unpaid interest was to be paid to Agility Capital, and all amounts outstanding on December 1, 2010 were due and payable at that time. In the event of a default, the interest rate will be increased to 5.0% above the rate that would otherwise apply, and in addition, Agility would receive a fee of $5,000, with an additional fee of $5,000 on each thirtieth day thereafter for so long as the event of default continues. Under the terms of this secured credit facility, GigOptix paid Agility Capital a $20,000 fee. On April 28, 2010, GigOptix paid Agility Capital $0.4 million to fully repay GigOptix’ liabilities covering principal and accrued interest related to GigOptix’ short-term loan. At this time this secured credit facility was cancelled.

Operating activities used cash of $3.8 million in the year ended December 31, 2010. This resulted primarily from a net loss of $4.4 million, an increase in accounts receivable of $1.6 million, an increase in inventories of $0.2 million, a decrease in accounts payable and accrued expenses of $2.6 million, and a decrease in other non-current liabilities of $0.5 million. These uses were partially offset by the following non-cash expenses:

depreciation and amortization of $2.4 million, stock-based compensation of $1.5 million, change in fair value of warrants recorded as a liability of $0.1 million, amortization of a discount on a loan of $0.4 million, warrant expense recorded in equity of $0.1 million, amortization of an acquisition related payment of $0.6 million, and the write-down of certain fixed assets and inventories of $0.2 million. The net loss decreased in 2010 from 2009 as a result of an 81% increase in revenues in 2010 compared to 2009. GigOptix was also able to reduce its accounts payable and current liabilities as a result of GigOptix’ equity raise in the third quarter of 2010.

Operating activities used cash in the year ended December 31, 2009 of $4.1 million, a result of a net loss of $10.0 million, decreases in inventories, prepaid expenses and other current assets totaling $0.7 million, partially offset by non-cash expenses for depreciation and amortization, stock-based compensation and intangible asset impairment of $1.1 million, $0.9 million and $0.4 million, respectively, an increase of $1.4 million in accrued and other current liabilities and an increase in accounts payable of $0.8 million.

Net cash used in investing activities for the year ended December 31, 2010 was $0.9 million and consisted of purchases of fixed assets of $1.2 million offset by refunds of restricted cash of $0.3 million related to GigOptix’ leased facilities in Bothell, WA. GigOptix reduced its square footage in Bothell by approximately 63% resulting in lower facility rent expense which led to a reduction in required restricted cash.

Net cash provided by investing activities for the year ended December 31, 2009 was $1.3 million and primarily consisted of net cash acquired in the acquisition of ChipX of $1.7 million, the sale of assets of Plexera for $0.3 million, and refunds of restricted cash of $0.1 million, offset by purchases of property and equipment of $0.8 million.

Net cash provided by financing activities was $5.6 million during the year ended December 31, 2010 and consisted of $4.1 million in proceeds from the issuance of common stock and the exercise of stock options, proceeds of $3.4 million from a line of credit and term loan from Silicon Valley Bank and Agility Capital, offset by repayments of loans to Bridge Bank, Agility Capital, and Silicon Valley Bank and the repayment of a capital lease obligation for engineering design software.

Net cash used in financing activities during the year ended December 31, 2009 was $0.5 million and consisted of $1.0 million in proceeds from the issuance of common stock and warrants, net proceeds from the line of credit of $2.1 million, offset by repayments under the line of credit and capital lease obligations of $3.5 million and $0.1 million, respectively.

GigOptix has incurred negative cash flows from operations since inception. For the years ended December 31, 2010 and 2009, GigOptix incurred net losses of $4.4 million and $10.0 million, respectively, and cash outflows from operations of $3.8 million and $4.1 million respectively. As of December 31, 2010 and 2009, GigOptix had an accumulated deficit of $73.4 million and $69.0 million, respectively. GigOptix has incurred significant losses since inception, attributable to GigOptix’ efforts to design and commercialize GigOptix’ products. GigOptix has managed GigOptix’ liquidity during this time through a series of cost reduction initiatives and through increasing GigOptix’ line of credit with Silicon Valley Bank. GigOptix’ ability to continue as a going concern is dependent on many events outside of GigOptix’ direct control, including, among other things; obtaining additional financing either privately or through public markets and consumers’ purchasing GigOptix’ products in substantially higher volumes. During 2010, GigOptix raised approximately $3.9 million in additional equity capital from institutional investors which stabilized GigOptix’ cash position. GigOptix has used that cash to substantially reduce its outstanding accounts payable and accrued expenses balances. In addition, GigOptix has access to a line of credit with Silicon Valley Bank which enables GigOptix to borrow up to $3 million based on 80% of eligible invoiced amounts to customers. GigOptix also was close to breakeven, incurring a loss of

$97,000, on an operating income basis in the fourth quarter of 2010. Additionally, GigOptix’ pending merger with Endwave upon closing will provide GigOptix with additional cash and equivalents which should mitigate near-term liquidity issues. Based on these events and factors, GigOptix believes it can continue as a going concern over the next 12 months.

GigOptix does not use off-balance-sheet arrangements with unconsolidated entities or related parties, nor does it use other forms of off-balance-sheet arrangements such as special purpose entities and research and development arrangements. Accordingly, GigOptix is not exposed to any financing or other risks that could arise if it had such relationships.

Endwave designs, manufactures and markets radio frequency, or RF, products that enable the transmission, reception and processing of high frequency RF signals. Endwave’s products consist of two key product lines, semiconductor devices and integrated transceiver modules:

Endwave was originally incorporated in California in 1991 and reincorporated in Delaware in 1995. In March 2000, Endwave merged with TRW Milliwave Inc., a RF sub-system supplier that was a wholly-owned subsidiary of TRW Inc. In connection with the merger, Endwave changed its name from Endgate Corporation to Endwave Corporation. On October 17, 2000, Endwave successfully completed the initial public offering of its common stock. Endwave’s principal executive offices are located at 130 Baytech Drive, San Jose, CA 95134 and its main telephone number is (408) 522-3100.

The applications of RF technology are broad, extending from terrestrial AM radio at the low end of the frequency spectrum, which is less than 1 MHz, to atmospheric monitoring applications at the high end of the frequency spectrum, which is around 100 GHz. Microwave technology refers to technology for the transmission of signals at high frequencies, from approximately 1 GHz to approximately 20 GHz and millimeter wave technology refers to technology for the transmission of signals at very high frequencies, from approximately 20 GHz to beyond 100 GHz. Endwave’s products employ both microwave and millimeter wave technology. The term microwave, however, is commonly understood in the industries Endwave serves, and that term is used in this prospectus/proxy statement as meaning both microwave and millimeter wave.

parts of the world, cellular backhaul is typically accomplished through the use of microwave radios either because of their ease of deployment and low overall cost relative to available wireline options or because adequate wireline facilities are not available. While in the United States and Canada cellular backhaul has typically been accomplished through the use of wireline facilities, there is a growing trend to migrate to microwave backhaul because wireline systems are not a practical alternative to provide the extremely high backhaul data rates necessitated by contemporary “smart phones” and similar devices.

Fixed Wireless Access Network Backhaul. Similar to the situation in cellular telephone networks, fixed wireless access networks require a backhaul infrastructure to move the data from individual access points to an internet portal. Various approaches are being considered for the widespread implementation of fixed wireless access networks, including the IEEE 802.16 WiMAX standard and LTE technology. Regardless of the underlying access technology, all such fixed wireless access networks will face the technological and cost issues associated with connecting individual access points to the wireline network infrastructure. Endwave believes this need for backhaul represents an opportunity for microwave radios, particularly because the anticipated high bandwidth requirements of fixed wireless access networks are served more cost-effectively by microwave radios than by wireline alternatives.

High-frequency RF technology is an integral part of various defense systems. Key applications in these markets include:

Because millimeter wave energy is both emitted by and reflected off of the human body, various sensors and imaging systems can be constructed to enhance the capability of personnel security systems.

The increasing concern over terrorist attacks in various public spaces is driving demand for these types of security systems and Endwave believes is creating new opportunities for its products.

Historically, when OEMs and other system integrators incorporated high-frequency RF technology into their products, they designed and manufactured all the requisite hardware internally. However, when faced with the

need to generate cost efficiencies and technological innovations with fewer resources, OEMs and system integrators frequently look to suppliers for these items. Endwave believes there are several key characteristics that define an attractive supply partner for fulfilling these requirements, including:

Technical Depth. OEMs and system integrators seek suppliers that have significant experience in and understanding of the overall system design. This depth and breadth of understanding is crucial to optimizing the system design and making appropriate overall system level tradeoffs, thereby enabling the OEM or system integrator to design and deploy its systems more cost-effectively.

Innovative Technology. New technology is the key to providing enhanced performance and continued cost reduction. Thus, OEMs and system integrators value this capability and prefer partners that create new technologies offering additional functionality, higher reliability, lower cost and better performance.

Semiconductor Devices. Beyond seeking complete hardware sub-systems, OEMs and system integrators may seek technologically advanced and cost effective semiconductor devices including custom design capabilities that meet their unique technological needs on existing or next generation hardware platforms.

Low Cost. OEMs and system integrators are under increasing pricing pressure from their customers and expect effective and persistent cost-reduction programs from their suppliers. These cost-reduction programs require suppliers to mount a comprehensive effort at multiple levels, including integration of multiple functions, efficient manufacturing, effective supply chain management, streamlined life cycle support and use of low cost sub-contractors.

Flexible Supply Chain Capabilities. Volatility of demand is common in the markets Endwave serves. Therefore OEMs and system integrators need suppliers that can accommodate fluctuations in the demand, whether in mix and/or quantity, and that can flexibly scale their manufacturing to match these fluctuating demands.

Endwave believes that few suppliers comprehensively address all of these requirements. Many of the suppliers that populate the industry are small and lack the requisite operational strength and technical capability to address these extensive needs and requirements. Further, many suppliers use labor-intensive assembly and test methods that limit their ability to produce high-frequency RF products in high volumes and at a low cost. Others do not possess the breadth of component-to-system expertise that is desired by OEMs and system integrators. In contrast, Endwave believes that it possesses several key strengths that enable it to provide its customers with superior products and services. These strengths include:

Extensive Technical Expertise. Endwave has extensive experience in all aspects of high frequency design and manufacturing. Its body of intellectual property and a highly-skilled technical team are critical when dealing with the higher frequencies required by emerging applications. Endwave’s technical team has broad expertise in device physics, semiconductor device and circuit design, system engineering, test engineering and other critical disciplines. In addition, its large library of proprietary designs enables it to introduce new products rapidly and cost-effectively. Endwave believes the depth and breadth of its technical expertise differentiates it from many of its competitors, enabling it to optimize its products for critical performance factors and to assist its customers in developing an optimal overall design.

A Commitment to Develop Next-Generation Technology. A key component of Endwave’s value proposition is providing its customers with powerful and cost-effective technologies that offer them a major technical and economic advantage. Endwave has invested in the development of next-generation circuit and packaging technologies that allow it to provide its customers with high-performance and low-cost solutions. Its ability to develop semiconductor devices on a custom basis provides Endwave greater flexibility to optimize product designs for its customers and their specific applications. Endwave intends to continue to invest in research and development, maintain a team of talented engineers, and build on its manufacturing technologies.

Comprehensive Approach to Cost-Effective Manufacturing. Endwave has taken a comprehensive approach to developing a cost-effective, outsourced manufacturing capability that allows it to compete on a worldwide basis and to offer its customers product solutions at attractive prices:

Integrated transceiver sub-system modules combine several functional RF blocks, such as amplifiers, mixers, switches or oscillators, with various types of control and support circuitry, such as a microprocessor or a power supply, to form a stand-alone transceiver sub-system. These complex modules, generally comprising hundreds of individual components, combine RF functions with sophisticated analog and digital system interface and control capabilities.

Within these modules, the core RF functions are performed with one of two circuit technologies:

In high-frequency RF modules, the circuit packaging technology also significantly impacts cost and performance. Many of Endwave’s newer products employ a unique packaging technology named Epsilon™. In this approach, MMIC or MLMS circuits are directly mounted to a composite printed wiring board and then enclosed with a metalized molded plastic or machined cover. The composite wiring board consists of a top RF circuit layer built on a low loss substrate with lower layers of the board consisting of conventional printed wiring board substrates for power and control circuitry. This approach reduces the size, weight and cost of the packaging components.

As noted above, in the course of developing several different transceiver module variants to meet a range of customer requirements, Endwave has designed a broad range of semiconductor devices including a large number of MMIC devices. The breadth and depth of this repertoire is such that Endwave can fulfill the requirements for most circuit functions in the frequency range of 10 GHz to 100 GHz. Endwave’s motivation to design these circuits has been to both achieve superior electrical performance and to reduce costs through vertical integration. Once designed, these devices are fabricated in several merchant foundries throughout the world. By using a mixture of foundries, Endwave is able to select the best foundry and fabrication process to achieve the desired performance in the most cost-effective manner. Endwave’s devices have been particularly designed to meet the high frequency and high bandwidth requirements of contemporary systems. In addition to the core devices, Endwave has developed a range of device packaging technologies that allow its circuits to be installed using industry standard surface mount technology, or SMT, assembly processes. Endwave has extended this technology such that devices operating at frequencies up to 50 GHz can be assembled in the SMT format, thus facilitating ease of downstream assembly of the sub-system module. In addition to supporting its transceiver product line, Endwave now offer these devices as stand-alone products to the various markets and applications noted above.

Endwave sells its products through direct sales efforts, a network of independent domestic and international representatives and a domestic distributor of semiconductor devices. For each of its major customers, Endwave assigns a technical account manager, who has responsibility for developing and expanding Endwave’s relationship with that customer. Endwave’s direct, representative and distributor sales efforts are augmented by traditional marketing activities, including advertising, participation in industry associations and presence at major trade shows.

Endwave’s products are highly technical and the sales cycle can often be long. Endwave’s sales efforts typically involve a collaborative and iterative process with its customers to determine their specific requirements, verify a product design and develop an effective manufacturing approach matched to the application. Depending on the product type and market, the sales cycle can typically take anywhere from 2 to 24 months.

In 2010, revenues from Endwave’s telecom OEM customers comprised nearly all of its total revenues. In 2010, three customers each accounted for greater than 10% of Endwave’s total revenues and combined they accounted for 93% of Endwave’s total revenues, the largest of which was Nokia Siemens Networks, which accounted for 52% of Endwave’s total revenues. Endwave expects revenues from its telecom OEM customers to comprise the large majority of its revenues in the immediate future. In the telecom market, Endwave’s revenues are attributable to a limited number of telecom OEMs and Endwave expects this pattern to remain for the foreseeable future.

The markets for Endwave’s products are extremely competitive, are characterized by rapid technological change and continuously evolving customer requirements and many of its competitors have significantly greater resources than Endwave does.

Among suppliers of transceiver modules in the telecommunication network market, Endwave competes with Compel Electronics SpA, Filtronic plc, Microelectronics Technology Inc., and Remec Broadband Wireless, Inc., among others. In addition to these companies, there are telecom OEMs, such as Ericsson and NEC Corporation, that use their own captive resources for the design and manufacture of transceiver modules, rather than using suppliers such as Endwave. While Endwave has limited opportunities to supply transceiver modules to these telecom OEMs, it believes that it has opportunities to supply them semiconductor devices for their captive products.

In the case of Endwave’s semiconductor product line, it competes with Avago Technologies, Ltd., Hittite Microwave Corp., MIMIX Broadband, Inc., RF Micro Devices, Inc., TriQuint Semiconductor, Inc. and United Monolithic Semiconductors, S.A.S., among others.

Endwave directs its research efforts towards developing advanced device, circuit and packaging technologies, creating new proprietary circuit designs and integrating these technologies and designs into the semiconductor devices it provides to its customers. Endwave’s product development activities focus on designing products to meet specific customer and market needs and introducing these products to manufacturing.

Semiconductor Design Capabilities. Endwave’s ability to design semiconductor devices allows it to optimize and reduce the cost of designs beyond what is possible with standard off-the-shelf semiconductor devices.

Breadth of Expertise. Endwave is experienced in a broad range of technical disciplines and possesses the know-how to design products at multiple levels of integration.

Computer Modeling Capabilities. Endwave’s extensive computer modeling capabilities allow it to create designs quickly and to minimize the number of iterations required to develop specification compliant, cost-effective designs.

Extensive Library of Designs. Endwave’s extensive library of device, circuit and sub-system designs enables it to generate new products and produce prototypes quickly to meet its customers’ time-to-market demands.

Automated Testing Processes. High-frequency RF products require extensive testing after assembly to verify compliance with customer specifications. Endwave uses high speed, custom-designed, automated test sets that

are capable of rapidly testing devices and modules. This increases throughput in the manufacturing process and reduces the skill level required to conduct the tests. Concurrently with the development of these test methods, Endwave develops data analysis and reporting tools to facilitate rapid communication of test data to its customers.

Endwave’s investment in research and development and related engineering projects has resulted in research and development expenses from continuing operations of $6.8 million, $5.5 million and $4.6 million in 2008, 2009 and 2010, respectively.

Endwave’s success depends, in part, on its ability to protect its intellectual property. Endwave relies primarily on a combination of patent, copyright, trademark and trade secret laws to protect its proprietary technologies and processes. As of December 31, 2010, Endwave had 43 United States patents issued, many with associated foreign filings and patents. Endwave’s issued patents include those relating to basic circuit and device designs, semiconductors, MLMS technology and system designs. Endwave’s United States patents expire between 2013 and 2028. Endwave does not anticipate the expiration of patents over the near term to have a significant impact on its research and development or operations. Endwave also licenses technology from other companies, including Northrop Grumman Corporation. There are no limitations on Endwave’s rights to make, use or sell products Endwave may develop in the future using the technology licensed to it by Northrop Grumman Corporation.

Endwave maintains a vigorous technology development program that routinely generates potentially patentable intellectual property. Its decisions as to whether to seek formal patent protection, and the countries in which to seek it, are taken on a patent-by-patent basis and are based on the economic value of the intellectual property, the anticipated strength of the resulting patent, the cost of pursuing the patent and an assessment of using a patent as an implement to protect the underlying intellectual property. With regard to Endwave’s pending patent applications, it is possible that no patents may be issued as a result of these or any future applications or the allowed patent claims may be of reduced value and importance. Further, any existing or future patents may be challenged, invalidated or circumvented thus reducing or eliminating their commercial value.

To protect its intellectual property, Endwave enters into confidentiality and assignment of rights to inventions agreements with its employees, and confidentiality and non-disclosure agreements with its strategic partners, and generally controls access to and distribution of its documentation and other proprietary information. These measures may not be adequate in all cases to safeguard the proprietary technology underlying Endwave’s products. It may be possible for a third party to copy or otherwise obtain and use Endwave’s products or technology without authorization, develop similar technology independently or attempt to design around its patents. In addition, effective patent, copyright, trademark and trade secret protection may be unavailable or limited outside of the United States, Europe and Japan.

All of Endwave’s manufacturing operations are located in Lamphun, Thailand and utilize the facilities of its contract manufacturing partner, HANA. Under its manufacturing contract, HANA supplies the physical plant, direct labor, basic assembly equipment and warehousing functions. Endwave supplements those activities with its own full-time, in-country staff consisting of 15 people who provide production planning, process engineering, test engineering, product support, design engineering and quality assurance support. Endwave owns certain assets held securely in HANA’s factory, including specialized test and assembly equipment and various raw material and product inventories. Endwave’s arrangement with HANA allows it to reduce its labor and facility expenses while maintaining tight control of process and quality. To reduce its costs further, Endwave has identified lower cost Asian sources for various raw materials, especially basic metal and circuit board components. Endwave’s manufacturing agreement with HANA currently expires in October 2011, but will renew automatically for

successive one-year periods unless either party notifies the other of its desire to terminate the agreement at least one year prior to the expiration of the term. In addition, either party may terminate the agreement without cause upon 365 days prior written notice to the other party, and either party may terminate the agreement if the non-terminating party is in material breach and does not cure the breach within 30 days after notice of the breach is given by the terminating party. There can be no guarantee that HANA will not seek to terminate its agreement with Endwave.

Endwave uses both industry-standard and Endwave-designed semiconductor devices. Endwave obtains industry-standard devices from various suppliers of these parts and contracts with various third-party foundries to produce Endwave’s own designs. Endwave’s use of third-party foundries for custom designed devices gives it the flexibility to use the process technology that is best suited for each application and eliminates the need for Endwave to invest in and maintain its own semiconductor facilities. While the loss of Endwave’s relationship with or Endwave’s access to any of the semiconductor foundries it currently uses, and any resulting delay or reduction in the supply of semiconductor devices to Endwave, would severely impact Endwave’s ability to fulfill customer orders and could damage its relationships with its customers, Endwave estimates that it could shift production to a new foundry within six months. Endwave currently uses the foundry services of Global Communication Semiconductors, Inc., M/A-COM Technology Solutions Inc., Northrop Grumman Space Technology, TriQuint Semiconductors and WIN Semiconductors Corp.

All of the manufacturing facilities Endwave operates or uses worldwide are registered under ISO 9001-2000, an international certification standard of quality for design, development and business practices. Additionally, Endwave is certified under AS-9100 in support of its defense industry market initiatives. Endwave maintains comprehensive quality systems at all of its facilities to ensure compliance with customer specifications, configuration control, documentation control and supplier quality conformance.

Endwave maintains raw materials, work-in-process and finished goods inventory in Thailand at HANA’s plant. In order to maintain and enhance its competitive position, Endwave must be able to satisfy its customers’ short lead-times and rapidly-changing needs. Meeting this requirement necessitates that Endwave maintain significant raw material and finished goods inventories. Maintaining these inventories is costly and requires significant working capital and may increase Endwave’s capital needs in the future.

Endwave’s backlog at January 15, 2011 for shipments expected to occur through December 31, 2011 was approximately $8.0 million. By comparison, Endwave’s backlog as of February 19, 2010 for shipments expected to occur through December 31, 2010 was approximately $23.4 million.

Endwave’s order backlog consists of a combination of conventional purchase orders and formal forecasts given to it under annual and multi-year agreements. Typically, the forecast portion of the backlog is the significantly larger amount. The forecasts Endwave receives normally have a firm commitment portion of one to three months in duration that obligate the customer to accept at least some portion of the amount forecasted for that period, with the remainder of the forecast including no such obligation. These forecasts are subject to change on a regular basis and Endwave has experienced significant forecast variations in both unit volumes and product mix. As a result, Endwave does not believe that backlog is a reliable indicator of future revenues.

Government regulations indirectly affect Endwave’s business. The frequencies at which wireless systems transmit and receive data are dictated by government licensing agencies in the location where they are deployed. Unexpected difficulties in obtaining licenses or changes in the operating frequencies allowed can halt or delay microwave radio deployments and therefore halt or delay the need for Endwave’s products. Both national and international regulatory bodies have set stringent standards on the performance of microwave radios, especially

spurious emissions and their potential to cause interference in other systems. Meeting these regulations is technologically challenging and changes in the regulations could require a re-design of Endwave’s products to achieve compliance. Also, on occasion Endwave is required to obtain various export permissions from the U.S. government to ship product to overseas customers.

The following table provides information regarding all plan and non-plan compensation awarded to, earned by or paid to the Chief Executive Officer and Chief Financial Officer of Endwave for all services rendered in all capacities to Endwave during 2008, 2009 and 2010. Endwave refers to these executive officers as Endwave’s specified executive officers. Mr. Mikulsky and Mr. Sacks are specified in this proxy statement/prospectus because they are expected to serve as a director and as an executive officer, respectively, of GigOptix, upon consummation of the merger.

The following table provides information with regard to potential cash bonuses paid or payable in 2010 under Endwave’s performance-based, non-equity incentive plan, and with regard to stock option and restricted stock units granted to each specified executive officer during 2010.

The following table provides information regarding each unexercised stock option and unvested restricted stock units held by each of Endwave’s specified executive officers as of December 31, 2010. Other than stock options/restricted stock units, or RSUs, as noted, there were no other stock awards outstanding at December 31, 2010.

There were no stock options exercised by Endwave’s specified executive officers during 2010.

Endwave’s executive compensation consists of base salary, annual cash incentive, equity plan participation and customary broad-based employee benefits. Consistent with Endwave’s pay for performance philosophy, the Endwave Compensation Committee believes that Endwave can better motivate executive officers to enhance stockholder return if a portion of their compensation is “at risk”— that is, contingent upon the achievement of performance objectives and overall strong company performance. The mix of base salary, annual cash bonus opportunity based on achievement of objectives and anticipated long-term stock-based compensation incentive (in the form of appreciation in shares underlying stock options) varies depending on the officer’s position level. Long-term stock-based compensation has always been a significant component of executive compensation, as Endwave believes that best aligns its executive officers’ interests with that of its stockholders. An annual cash bonus opportunity has historically also formed a significant component of executive compensation; however, as explained in more detail below, it was not a component of executive compensation in 2010 and is not likely to form a significant component of executive compensation in 2011.

Base Salary: Base salaries for Endwave executives are established based on the scope of their responsibilities, taking into account market compensation paid by comparable companies for equivalent positions. Base salaries are reviewed on an annual basis and any increases are similar in scope to the overall corporate salary increase of Endwave. For comparison purposes, Endwave has utilized compensation survey data from Radford. Endwave’s philosophy is to target executive base salaries near the median range of salaries for executives in equivalent positions at comparable companies. Endwave believes targeting executive salaries at the median relative to comparable companies reflects its best efforts to ensure it is neither overpaying nor underpaying its executives.

Annual Cash Incentive: Endwave’s executive cash incentive compensation plan typically provides for a cash bonus award, payable once per year, that is dependent, in part, upon attaining stated corporate objectives for the prior fiscal year. The goal of our executive cash incentive compensation plan is to reward executives in a manner that is commensurate with the level of achievement of certain financial and strategic goals that Endwave believes, if attained, result in greater long-term shareholder value. The Compensation Committee of Endwave approves these financial and strategic goals on an annual basis. These financial and strategic goals typically have a one-year time horizon. During 2009, and continuing through 2010, Endwave’s Compensation Committee suspended the cash incentive compensation plan due to the difficult economic environment and its impact on Endwave’s financial performance. Therefore, the Compensation Committee determined there would be no payment of 2010 annual bonuses for Endwave’s Chief Executive Officer or its other officers. For 2011, Endwave’s Compensation Committee has not established any cash incentive program, but may determine to award bonuses on a discretionary basis, which it currently does not intend to do unless Endwave is profitable in 2011.

Stock Options and Restricted Stock Units: Endwave believes that stock ownership is an important factor in aligning corporate and individual goals. Therefore, Endwave utilizes stock options and, beginning in 2010, restricted stock units, to encourage long-term performance, with excellent corporate performance (as manifested in our common stock price) and extended officer tenure producing potentially significant value. Upon joining Endwave, executive officers have received an initial stock option grant. This grant has been based on relevant industry comparisons, including data from Radford, and was intended to be commensurate with the experience

level and scope of responsibilities of the incoming executive officer. In addition, all executive officers receive annual option grants, and beginning in 2010, restricted stock unit grants. On an annual basis, the Compensation Committee reviews with the Board the percentage ownership of Endwave held by employees, and compares that to the employee ownership of comparable companies. The Compensation Committee uses this metric because it is easy to measure and compare to comparable companies. Based on its review, the Compensation Committee approves an annual grant. For 2010, the aggregate annual grant to all employees was approximately 3.6% of fully-diluted shares.

All option and restricted stock unit grants are approved by the Compensation Committee at Endwave’s regular quarterly Board of Directors meeting. The options and restricted stock units are approved so that the grant date is three days after the release of our financial results for the preceding quarter. The exercise price for option awards is determined as the closing price on the day prior to grant. As permitted under U.S. generally accepted accounting principles, Endwave has historically determined fair market value under its stock option plans based upon the closing market price as reported by the Nasdaq Global Market for the day preceding the date of grant.

Other Benefits: Executive officers are eligible to participate in all of Endwave’s employee benefit plans, such as medical, dental, group life, disability, and accidental death and dismemberment insurance, Endwave’s 401(k) plan and its 2000 Employee Stock Purchase Plan. During 2010, Endwave made group life insurance payments as reflected in the Summary Compensation Table. Endwave does not maintain any pension plan, retirement benefit or deferred compensation arrangements other than its 401(k) plan. During 2009, and continuing into 2010, Endwave suspended its program applicable to all of its 401(k) plan participants under which it matched 50% of employee contributions up to a maximum of 4% of base salary.

In general, the factors utilized in determining Mr. Mikulsky’s compensation were similar to those applied to the other executive officers in the manner described in the preceding paragraphs. A significant percentage of his potential compensation was, and continues to be, subject to consistent, positive, long-term company performance. Based on a review of the above mix of factors, for 2010, the Compensation Committee granted to Mr. Mikulsky compensation as detailed in the Summary Compensation Table. Based on these figures, over 47% of Mr. Mikulsky’s total compensation (measured according to the Summary Compensation Table and reflecting the Estimated Possible Target Payout as discussed in the Grants of Plan-Based Awards Table) was based on variable components such as stock options.

Endwave believes that the retention of its executive officers is critical to its business. Given the competitive nature of the technology industry, the demand for experienced executives is high. Moreover, the level of involuntary terminations of executives in the technology industry is high. In order to encourage Endwave’s key employees to remain with Endwave, Endwave’s board of directors has established and maintains its Senior Executive Officer Severance and Retention Plan and its Executive Officer Severance Plan. Endwave’s Chief Executive Officer participates in the Senior Executive Officer and Retention Plan and Endwave’s Senior Vice Presidents participate in the Executive Officer Severance Plan.

Executive Officer Severance and Retention Plan Assuming No Change of Control: Under the Senior Executive Officer Severance and Retention Plan, if Endwave’s Chief Executive Officer is terminated without cause, or resigns for certain specified reasons constituting constructive termination, the executive officer will receive (i) salary and benefits continuation based on the executive officer’s position and length of service with Endwave and (ii) acceleration of vesting of all of his stock options. The salary and benefits continuation period for Endwave’s Chief Executive Officer will be equal to the greater of 1.5 months for every year of service to Endwave, or a total of nine months, if the termination of employment does not occur in connection with a change of control transaction.

Under the Executive Officer Severance Plan, if a participating executive officer is terminated without cause, or resigns for certain specified reasons constituting constructive termination, the executive officer will receive salary and benefits continuation based on the executive officer’s position and length of service with Endwave. In the case of the participating Senior Vice Presidents, the salary and benefits continuation period will be equal to the greater of six months or one month for every year of service to a maximum of twelve months, if the termination of employment does not occur in connection with a change of control transaction.

The following table shows the potential payout to Endwave’s Chief Executive Officer and Chief Financial Officer assuming termination does not occur in connection with, or within six months after, a change of control. The analysis assumes the employees were terminated without cause on December 31, 2010:

Executive Officer Severance and Retention Plan Assuming a Change of Control: The Compensation Committee believes that it is in the best interests of stockholders if Endwave’s executive officers are able to focus on Endwave’s business during both strong and weak business cycles without being distracted by the near-term financial impact that a potential termination of employment might have on them personally. The Compensation Committee also believes it is in the best interests of stockholders if Endwave’s executive officers are able to evaluate the potential merits of a change of control transaction objectively without being distracted by the potentially adverse personal impact on themselves. The Compensation Committee believes that the total potential value of all change of control agreements with Endwave’s executive officers is not disproportionate to the overall market value of Endwave.

Under the Senior Executive Officer Severance and Retention Plan, if Endwave’s Chief Executive Officer is terminated without cause, or resigns for certain specified reasons constituting constructive termination, he will receive (i) salary and benefits continuation based on his length of service with Endwave and (ii) acceleration of vesting of all of his stock options. If Endwave’s Chief Executive Officer’s employment is terminated by Endwave without cause or by the Chief Executive Officer for certain specified reasons in connection with, or within six months after, the change of control transaction, the Chief Executive Officer will receive salary continuation for twice the period that would have applied had such termination not occurred in connection with a change of control as well as the acceleration of vesting of all of his stock options.

Under the Executive Officer Severance Plan, if an executive officer is terminated without cause, or resigns for certain specified reasons constituting constructive termination, the participating Senior Vice Presidents will receive salary and benefits continuation based on the length of service with Endwave. Upon the closing of a change of control transaction, if an executive officer’s employment is terminated by Endwave without cause or

by the executive officer for certain specified reasons in connection with, or within six months after, the change of control transaction, the executive officer will receive salary continuation for twelve months and the accelerated vesting for all of the executive officer’s outstanding stock options.

The following table shows the potential payout to the specified executive officers under Endwave’s Senior Executive Officer Severance and Retention Plan and Endwave’s Executive Officer Severance and Retention Plan assuming termination occurs in connection with, or within six months after, a change of control. The analysis assumes the employees were terminated without cause on December 31, 2010:

The following table provides information regarding compensation paid to Joseph J. Lazzara, a non-employee director who served on Endwave’s board as of December 31, 2010. Mr. Lazzara is expected to be appointed as a director of GigOptix upon closing of the merger.

Although Endwave has experienced significant quarterly fluctuations in revenue at times over the past several years, it does not believe that volatility was primarily attributable to seasonality in its business.

As of December 31, 2010, Endwave had 51 regular employees, including 33 in product and process engineering, 8 in sales and marketing and 10 in general and administrative. Of its regular employees, 15 are based in Endwave’s Chiang Mai, Thailand office. Endwave’s employees are not subject to any collective bargaining agreement with Endwave and it believes that its relations with its employees are good.

On October 31, 2008, Endwave filed a complaint with the Canadian Superior Court in Montreal, Quebec alleging that Advantech Advanced Microwave Technologies Inc., or Advantech, the parent company of Allgon Microwave Corporation AB, or Allgon, had breached its contractual obligations with Endwave and owes Endwave $994,500 in a note receivable, purchased inventory and authorized and accepted purchase orders resulting in shippable finished goods. Endwave cannot predict the outcome of these proceedings. An adverse decision in these proceedings could harm its consolidated financial position and results of operations.

In a related action, Endwave has filed a creditor’s claim for $994,500 against Allgon in the composition of creditors’ proceedings now pending in a Stockholm, Sweden bankruptcy court. Although a recovery under Swedish bankruptcy law is not assured, if it occurs any recovery will be a set-off in the Montreal action against Allgon’s parent, Advantech.

Endwave is not a party to any other material legal proceeding ths is expected to have a material adverse effect on its consolidated financial statements or results of operations. From time to time, Endwave may be subject to legal proceedings and claims in the ordinary course of business. These claims, even if not meritorious, could result in the expenditure of significant financial resources and diversion of management efforts.

ENDWAVE’S MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Endwave designs, manufactures and markets RF products that enable the transmission, reception and processing of high frequency RF signals. Endwave’s products consist of two key product lines, semiconductor devices and integrated transceiver modules:

Telecommunications market. Most of Endwave’s RF modules are deployed in telecommunication networks, carrier class trunking networks and point-to-point transmission networks. Its target customers for these applications are telecom OEMs. Telecom OEMs provide the equipment used by service providers to deliver voice, data and video services to businesses and consumers.

Non-telecommunication markets. Endwave’s RF semiconductors are also designed into various applications outside of the telecommunication network market, including defense and homeland security markets. Endwave’s target customers in the defense market include defense systems integrators and their subcontractors that design aerospace systems, defense systems and weapons and electronics platforms for both domestic and foreign defense customers. Endwave’s target customers in the homeland security market include those utilizing the properties of high-frequency RF energy to create systems designed to detect and identify security threats.

2010 revenues. During 2010, total revenues decreased by $2.8 million, or 14%, from 2009. Endwave believes the demand for its products has declined relative to prior periods due to a rapid drop in demand for legacy radio platforms and the decline of its key customers’ market share in the face of increasing competition. During 2010, Endwave began the production ramp of its new module designs supporting next-generation radios, but the revenues from the new module designs did not offset the decline in revenues from its legacy products.

Current market outlook. Endwave depends on a small number of key customers in the mobile communication industry for a significant portion of its revenues. Over the past year, Endwave’s customers have faced increasing competition, which Endwave believes has resulted in their loss of market share. The decline in Endwave’s key customers’ market share has led to decreased demand for Endwave’s products and contributed to the reduced revenues it experienced in 2010. Endwave is uncertain about its customers’ ability to regain market share given the competitive nature of the industry and therefore has limited visibility to its financial performance in 2011. Endwave currently believes that first quarter 2011 revenues will be significantly below the $4.1 million in revenue that it experienced in both the third and fourth quarters of 2010 and that revenues for all of 2011 will decrease from 2010.

On April 30, 2009, Endwave entered into an Asset Purchase Agreement with Microsemi Corporation, or Microsemi, pursuant to which Microsemi purchased Endwave’s Defense and Security RF module business, including all of the outstanding capital stock of its subsidiary, Endwave Defense Systems Incorporated. As consideration, Microsemi assumed certain liabilities associated exclusively with the Defense and Security RF module business and paid $28.0 million in cash. Additionally, as part of the sale, approximately 130 employees associated with the Defense and Security RF module business transferred to Microsemi. Accordingly, Endwave reclassified the results of its Defense and Security RF module business as a discontinued operation in its consolidated statements of operations for all periods presented in this proxy statement/prospectus, and all amounts set forth in this Management’s Discussion and Analysis of Financial Condition and Results of Operation reflect such reclassification.

This management’s discussion and analysis of Endwave’s financial condition and results of operations is based upon Endwave’s consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these consolidated financial statements requires Endwave to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, Endwave evaluates its estimates, including those related to revenue recognition, allowance for doubtful accounts, warranty obligations, inventories, stock-based compensation, income taxes, asset impairments and other commitments and contingencies. Endwave bases its estimates on historical experience and on various other assumptions that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates or Endwave’s estimates may be affected by different assumptions or conditions. These policies, as well as the estimates and judgments involved, are discussed below.

Endwave’s primary customers are telecom OEMs and other systems integrators that incorporate Endwave’s products into their systems. Endwave recognizes product revenues at the time title passes, which is generally upon product shipment, coupled with persuasive evidence that an arrangement exists, delivery has occurred or services have been rendered, Endwave’s price to the buyer is fixed or determinable and collectibility is reasonably assured. Revenues under development contracts are generally recorded on a percentage of completion basis, using project hours as the basis to measure progress toward completing the contract and recognizing revenues. Alternatively, where a development contract specifies defined progress gates or milestones tied to payments, revenue is recognized on a pro rata basis matching the milestones. Revenues attributable to development fees were insignificant during 2008, 2009 and 2010. The costs incurred under these development agreements are included in research and development expenses.

Endwave makes ongoing assumptions relating to the collectibility of its accounts receivable in its calculation of the allowance for doubtful accounts. In determining the amount of the allowance, Endwave makes judgments about the creditworthiness of customers based on ongoing credit evaluations and assesses current economic trends affecting its customers that might impact the level of credit losses in the future and result in different rates of bad debts than previously seen. Endwave also considers its historical level of credit losses. At December 31, 2009 and 2010, Endwave’s allowances were $19,000 and $18,000, respectively. If actual credit losses were to be significantly greater than the reserves Endwave has established, its selling, general and administrative expenses would increase.

Endwave generally offers a 12 to 30 month warranty on all of its products. Endwave records a liability based on estimates of the costs that may be incurred under its warranty obligations and charges to cost of product revenues the amount of such costs at the time revenues are recognized. Endwave’s warranty obligation is affected by product failure rates, material usage and service delivery costs incurred in correcting a product failure. Its estimates of anticipated rates of warranty claims and costs per claim are primarily based on historical information and future forecasts. At December 31, 2009 and 2010, Endwave’s warranty reserves were $1.1 million and $614,000, respectively. Endwave periodically assesses the adequacy of its recorded warranty reserve and adjusts the amounts as necessary. If actual warranty claims are significantly higher than forecasted, or if the actual costs incurred to provide the warranty is greater than the forecast, Endwave’s gross margins could be adversely affected.

Endwave evaluates its ending inventories for excess quantities and obsolescence at each balance sheet date. This evaluation includes review of materials usage, market conditions and product life cycles and an analysis of sales levels by product and projections of future demand and market conditions. Endwave adjusts inventory balances to approximate the lower of its manufacturing cost or market value. If actual future demand or market conditions are less favorable than those projected by management, additional inventory write-downs may be required, and would be reflected in cost of product revenues in the period the revision is made. This would have a negative impact on Endwave’s gross margins in that period. At the time of write down, a new, lower cost basis for that inventory is established and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. If in any period Endwave is able to sell inventories that were not valued or that had been written off in a previous period, related revenues would be recorded without any offsetting charge to cost of product revenues, resulting in a net benefit to its gross margin in that period. To the extent these factors materially affect its gross margins, Endwave discloses them. During 2010 and 2009, Endwave recorded $1.8 million and $878,000, respectively, of inventory write-offs associated with excess and obsolete material related to a rapid drop in sales of a legacy product for a major customer’s radio platform.

Endwave’s stock-based compensation cost is measured at the grant date, based on the fair value of the award, and is recognized as expense over the requisite service period. All of Endwave’s stock compensation is accounted for as an equity instrument.

For restricted stock units, stock-based compensation is based on the fair value of Endwave’s common stock at the grant date.

Endwave estimates the fair value of stock options and shares under its stock purchase plan using the Black-Scholes valuation model. The fair value of each option grant and the right to purchase shares under Endwave’s stock purchase plan are estimated on the date of grant using the Black-Scholes option valuation model and the graded-vesting method with assumptions concerning expected dividend yield, stock price volatility, risk free interest rate and expected life of the award.

The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. As Endwave’s stock option awards have characteristics that differ significantly from traded options, and as changes in the subjective assumptions can materially affect the estimated value, its estimate of fair value may not accurately represent the value assigned by a third party in an arms-length transaction. There currently is no market-based mechanism to verify the reliability and accuracy of the estimates derived from the Black-Scholes option valuation model or other allowable valuation models, nor is there a means to compare and adjust the estimates to actual values. While Endwave’s estimate of fair value and the associated charge to earnings materially affects its results of operations, it has no impact on its cash position.

Endwave currently has significant deferred tax assets, which are subject to periodic recoverability assessments. Endwave records a valuation allowance to reduce its deferred tax assets to the amount that it believes to be more likely than not realizable. Endwave has recorded a valuation allowance in an amount equal to the net deferred tax assets to reflect uncertainty regarding future realization of these assets based on past performance and the likelihood of realization of its deferred tax assets.

Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. Intangible assets resulting from the acquisitions of entities accounted for using the purchase method of accounting are estimated by management based on the fair value of assets received.

During the fourth quarter of 2008, Endwave determined that indicators of potential impairment were present based on the fair value of its common stock relative to its book value, revised estimates for future revenues and the continued worsening of the global economy. As a result, Endwave assessed the carrying value of acquired goodwill and intangible assets with an indefinite life for impairment. Based on the fair market value of the business and its discounted future cash flow and revenue projections, Endwave recorded non-cash impairment charges of $3.0 million for goodwill and $1.1 million for intangible assets with an indefinite life. These impairment charges are included in discontinued operations.

Endwave reviews long-lived assets for impairment, whenever certain events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable. Such events or circumstances include, but are not limited to, a prolonged industry downturn, or a significant reduction in projected future cash flows.

For long-lived assets used in operations, Endwave records impairment losses when events and circumstances indicate that these assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amounts of those assets. If less, the impairment losses are based on the excess of the carrying amounts over their respective fair values. Their fair values would then become the new cost basis. Fair value is determined by discounted future cash flows, appraisals, or other methods. For assets to be disposed of other than by sale, impairment losses are measured as the excess of their carrying amount over the salvage value, if any, at the time the assets cease to be used.

During the fourth quarter of 2008, Endwave reviewed its long-lived assets for indicators of impairment. Based on reduced estimates of future revenues and future negative cash flow, Endwave identified potential indicators of impairment. As a result, Endwave compared the fair value of its long-lived assets to their carrying value. Based on its discounted future cash flow and revenue projections, Endwave recorded non-cash impairment charges of $2.1 million for intangible assets with a defined useful life. These impairment charges are included in discontinued operations and represent the excess of the carrying value of these assets over their fair value.

These impairment charges are not expected to result in any future cash expenditures.

Endwave’s financial assets and liabilities are valued using market prices on both active markets (Level 1) and less active markets (Level 2). Level 1 instrument valuations are obtained from real-time quotes for transactions in active exchange markets involving identical assets. Level 2 instrument valuations are obtained from readily-available pricing sources for comparable instruments. As of December 31, 2010, Endwave did not have any assets or liabilities without observable market values that would require a high level of judgment to determine fair value (Level 3).

For Endwave’s business combinations, the purchase price of an acquired company is allocated between the intangible assets and the net tangible assets of the acquired business with the residual of the purchase price recorded as goodwill. The valuation of intangible assets is based on an income approach methodology that values the intangible assets based on the future cash flows that could potentially be generated by the asset over its estimated remaining life discounted to its present value utilizing an appropriate weighted average cost of capital. As a result of business acquisitions, the allocation of the purchase price to goodwill and intangible assets could have a significant impact on Endwave’s future operating results.

The following tables set forth selected consolidated statements of operations data for each of the periods indicated in dollars and as a percentage of total revenues.

Total revenues primarily consist of product revenues for sales of Endwave’s transceiver module and semiconductor products.

Total revenues decreased by $2.8 million, or 14%, from 2009 to 2010 due to a rapid drop in demand for legacy radio platforms and the decline of Endwave’s key customers’ market share in the face of increasing competition. During 2010, Endwave began the production ramp of its new module designs supporting next-generation radios but, the revenues from the new module designs did not offset the decline in revenues from its legacy product.

Over the past year, Endwave’s customers have faced increasing competition, which Endwave believes has resulted in their loss of market share. The decline in Endwave’s key customers’ market share has led to decreased demand for Endwave’s products and contributed to the reduced revenues it experienced in 2010. Endwave is uncertain about its customers’ ability to regain market share given the competitive nature of the industry and therefore has limited visibility to its financial performance in 2011. Endwave currently believes that first quarter 2011 revenues will be significantly below the $4.1 million in revenue that it experienced in both the third and fourth quarters of 2010 and that revenues for all of 2011 will decrease from 2010.

Cost of product revenues consists primarily of: costs of direct materials; equipment depreciation; costs associated with procurement, production control, quality assurance and manufacturing engineering; fees paid to Endwave’s offshore manufacturing vendor; reserves for potential excess or obsolete material; costs related to stock-based compensation; and accrued costs associated with potential warranty returns offset by the benefit of usage of materials that were previously written off.

During 2010, the cost of product revenues as a percentage of revenues increased compared to 2009, primarily due to the write-off of inventory associated with excess material related to a rapid drop in sales of a legacy product for a major customer’s radio platform, the decreased absorption of Endwave’s overhead costs resulting from decreased production and continued pricing pressure resulting in lower product margins. During 2010 and 2009, Endwave recorded $1.8 million and $878,000, respectively, of inventory write-offs associated with excess and obsolete material related to a rapid drop in sales of a legacy product for a major customer’s radio platform. The cost of product revenues in both periods was favorably impacted by the utilization of inventory that was previously written off, amounting to approximately $524,000 during 2010 and $100,000 during 2009.

Endwave continues to focus on reducing the cost of product revenues as a percentage of total revenues through the introduction of new designs and technology and further improvements to its offshore manufacturing processes. In addition, its product costs are impacted by the mix and volume of products sold and will continue to fluctuate as a result.

Research and development expenses consist primarily of salaries and related expenses for research and development personnel, outside professional services, prototype materials, supplies and labor, depreciation for related equipment, allocated facilities costs and expenses related to stock-based compensation.

During 2010, research and development costs decreased in absolute dollars compared to 2009 primarily due to a $528,000 decrease in personnel-related expenses, a $290,000 decrease in stock-based compensation expenses and a $25,000 decrease in project related expenses. The decrease in personnel-related expenses is primarily due to the restructuring activities undertaken during fiscal 2009.

Endwave has limited visibility to its research and development expenses for 2011 because it and GigOptix are in the process of determining the structure for the combined companies.

Sales and marketing expenses consist primarily of salaries and related expenses for sales and marketing personnel, professional fees, facilities costs, expenses related to stock-based compensation and promotional activities.

During 2010, sales and marketing expenses were comparable to the expenses in 2009 primarily due to a $320,000 decrease in stock-based compensation and a $107,000 decrease in bad debt expense, which were offset by a $259,000 increase in sales commissions, a $92,000 increase in marketing expenses, a $47,000 increase in travel expenses and a $29,000 increase in personnel-related expenses.

Endwave has limited visibility to its sales and marketing expenses for 2011 because it and GigOptix are in the process of determining the structure for the combined companies.

General and administrative expenses consist primarily of salaries and related expenses for executive, finance, accounting, legal, information technology and human resources personnel, professional fees, facilities costs, and expenses related to stock-based compensation.

During 2010, general and administrative expenses were $4.0 million compared to $5.6 million in 2009. The decrease in general and administrative expenses was primarily due to a $846,000 decrease in personnel-related expenses and a $815,000 decrease in stock-based compensation, which were partially offset by a $28,000 increase for professional fees. The decrease in personnel-related expenses is primarily due to the restructuring activities undertaken during fiscal 2009.

Endwave has limited visibility to its general and administrative expenses for 2011 because it and GigOptix are in the process of determining the structure for the combined companies.

During the first quarter of 2009, Endwave undertook certain restructuring activities to reduce expenses. These terminations affected all areas of Endwave’s operations. The components of the restructuring charge included severance, benefits, payroll taxes and other costs associated with employee terminations. The net charge for these restructuring activities in the first quarter of 2009 was $1.2 million and all cash payments have been made. Of this amount, approximately $182,000 has been included in income from discontinued operations. During the first quarter of 2010, Endwave recorded a $14,000 positive adjustment as a result of lower benefit charges in connection with its first quarter 2009 restructuring plan than were originally anticipated.

During the second quarter of 2009, Endwave undertook certain additional restructuring activities to reduce expenses. These terminations affected all areas of its operations. The components of the restructuring charge included severance, benefits, payroll taxes and other costs associated with the employee terminations. The net charge for these restructuring activities was $243,000 and all cash payments have been made. Of this amount, approximately $39,000 has been included in the discontinued operations line item on the consolidated statements of operations.

During the fourth quarter of 2009, Endwave undertook certain additional restructuring activities, including the departure of a senior executive, to reduce expenses. The components of the restructuring charge included severance, benefits, payroll taxes and other costs associated with employee terminations. The net charge for these restructuring activities was $1.2 million. The remaining restructuring liability of $665,000 at December 31, 2010 is expected to be substantially paid by the end of the third quarter of 2012.

During the third quarter of 2010, Endwave undertook certain additional restructuring activities to reduce expenses. The components of the restructuring charge included severance, benefits, payroll taxes and other costs associated with an employee termination. The net charge for these restructuring activities was $63,000 and all cash payments have been made.

Although Endwave currently anticipates the integration of Endwave and GigOptix to include some restructuring activities, Endwave and GigOptix have not yet determined the final structure for the combined companies.

Interest and other income, net consists primarily of interest income earned on Endwave’s cash, cash equivalents and investments, the amortization of the deferred gain from the sale of its Diamond Springs, California location, which ended in June 2009, and gains and losses related to foreign currency transactions.

The decrease in interest and other income from 2009 to 2010 was primarily the result of decreased interest earned on Endwave’s investments and increased interest expense for Endwave’s long-term restructuring liability.

During 2010, Endwave earned $80,000 of interest income, which was offset by interest expense, banking charges and losses on foreign currency transactions. During 2009, Endwave earned $205,000 of interest income and recognized $76,000 of other income from the amortization of the deferred gain from the sale of its Diamond Springs, California location, which was partially offset by banking charges and losses on foreign currency transactions.

Endwave’s functional currency is the U.S. Dollar. Transactions in foreign currencies other than the functional currency are remeasured into the functional currency at the time of the transaction. Foreign currency transaction losses consist of the remeasurement gains and losses that arise from exchange rate fluctuations related to its operations in Thailand. During 2010 and 2009, Endwave recorded foreign currency transaction losses of $6,000 and $15,000, respectively.

During 2009, Endwave recorded an income tax benefit of $105,000, due to a benefit from refundable research and development tax credits in the United States. During 2010, Endwave did not record any income tax benefit because the research and development tax credit was not refundable.

No other income tax expense (benefit) has been recorded because Endwave has incurred operating losses that cannot be benefitted due to a full valuation allowance.

On April 30, 2009, Endwave entered into an Asset Purchase Agreement with Microsemi pursuant to which Microsemi purchased its Defense and Security RF module business including all of the outstanding capital stock of Endwave Defense Systems Incorporated. As consideration, Microsemi assumed certain liabilities associated exclusively with the Defense and Security RF module business and paid $28.0 million in cash.

Total revenues decreased by $19.2 million, or 50%, from 2008 to 2009. The demand for Endwave’s products has declined relative to prior periods as the mobile communication industry has been impacted to a significant degree by the current global economic downturn and credit crisis. Additionally, during the second half of 2009 a key legacy product for a major customer’s radio platform experienced a rapid and unanticipated drop in sales while sales of Endwave’s new module designs supporting next-generation radios were just beginning their production ramp. The revenues from the new module designs did not offset the decline in revenues from the legacy product.

During 2009, the cost of product revenues as a percentage of revenues increased compared to 2008, primarily due to the decreased absorption of Endwave’s overhead costs resulting from decreased production, continued pricing pressure resulting in lower product margins, an $878,000 increase in inventory reserves due to excess material related to a rapid and unanticipated drop in sales of a legacy product for a major customer’s radio platform and an $86,000 increase in reserve for material related to a product built for a customer currently in bankruptcy liquidation. The cost of product revenues in both periods was favorably impacted by the utilization of inventory that was previously written off, amounting to approximately $100,000 during 2009 and $85,000 during 2008.

During 2009, Endwave undertook certain restructuring activities to reduce expenses, which resulted in a decrease of 21 product and process engineering employees and $808,000 in associated personnel-related expenses. In addition, during 2009, research and development costs decreased compared to 2008 due to a decrease of $317,000 for stock-based compensation expenses and a decrease of $209,000 for project-related expenses.

During 2009, sales and marketing expenses were $2.2 million compared to $3.4 million in 2008. During 2009, Endwave undertook certain restructuring activities to reduce expenses, which resulted in a decrease of three sales and marketing employees and $498,000 in associated personnel-related expenses. In addition, during 2009 sales and marketing expenses decreased compared to 2008 due to a decrease of $250,000 for stock-based compensation expenses and a decrease of $184,000 for bad debt expenses.

During 2009, general and administrative expenses were $5.6 million compared to $7.5 million in 2008. During 2009, Endwave undertook certain restructuring activities to reduce expenses, which resulted in a decrease of ten general and administrative employees and $798,000 in associated personnel-related expenses. In addition, during 2009, general and administrative expenses decreased compared to 2008 primarily due to a decrease of $468,000 for professional fees and a decrease of $320,000 for stock-based compensation expenses.

During the first quarter of 2009, Endwave undertook certain restructuring activities to reduce expenses. These terminations affected all areas of its operations. The components of the restructuring charge included severance, benefits, payroll taxes and other costs associated with employee terminations. The net charge for these restructuring activities in the first quarter of 2009 was $1.2 million and all cash payments have been made. Of this amount, approximately $182,000 has been included in income (loss) from discontinued operations.

During the second quarter of 2009, Endwave undertook certain additional restructuring activities to reduce expenses. The components of the restructuring charge included severance, benefits, payroll taxes and other costs associated with employee terminations. The net charge for these restructuring activities in the second quarter of 2009 was $243,000 and all cash payments have been made. Of this amount, approximately $39,000 has been included in income (loss) from discontinued operations.

During the fourth quarter of 2009, Endwave undertook certain additional restructuring activities to reduce expenses. The components of the restructuring charge included severance, benefits, payroll taxes and other costs associated with employee terminations. The net charge for these restructuring activities in the fourth quarter of 2009 was $1.2 million and is expected to be substantially completed by the end of the third quarter of 2012.

At December 31, 2008, Endwave had 228 employees. At December 31, 2009, Endwave had 54 employees. The decrease in employees was due to the restructuring mentioned above and the sale of Endwave’s Defense and Security RF module business to Microsemi.

The decrease in interest and other income from 2008 to 2009 was primarily the result of decreased interest earned on Endwave’s investments. Interest rates decreased significantly from the prior year, especially on the highest rated investment vehicles, leading to lower interest income.

During 2009, Endwave earned $205,000 of interest income and recognized $76,000 of other income from the amortization of the deferred gain from the sale of its Diamond Springs, California location, which was partially offset by banking charges and losses on foreign currency transactions. During 2008, Endwave earned $1.1 million of interest income and recognized $154,000 of other income from the amortization of the deferred gain from the sale of its Diamond Springs, California location, which was partially offset by banking charges and losses on foreign currency transactions.

During 2009 and 2008, Endwave recorded foreign currency transaction losses of $15,000 and $59,000, respectively.

During 2009 and 2008, Endwave recorded an income tax benefit of $105,000 and $66,000, respectively, due to a benefit from refundable research and development tax credits in the United States. No other income tax expense (benefit) has been recorded because Endwave incurred operating losses that cannot be benefitted due to a full valuation allowance.

Endwave classified the results of the Defense and Security RF module business as a discontinued operation in its consolidated statements of operations for all periods presented. During 2009, Endwave recognized income from discontinued operations of $17.6 million net of tax expenses. The income was a result of the gain on sale of the discontinued operations of $19.6 million partially offset by a $2.0 million loss from the discontinued operations in 2009. During 2008, Endwave recognized loss from discontinued operations of $10.8 million, which included $6.1 million of impairment charges for the Defense and Security RF module business’ goodwill and intangible assets.

At December 31, 2010, Endwave had $7.1 million of cash and cash equivalents, $16.4 million in short-term investments, working capital of $26.6 million and no long-term or short-term debt outstanding. The following table sets forth selected consolidated statements of cash flows data for Endwave’s three most recent fiscal years.

During 2010, operating activities used $5.5 million of cash compared to $4.1 million of cash in 2009. Endwave’s net loss from continuing operations, adjusted for depreciation and other non-cash items, was a loss of $6.5 million in 2010 as compared to $7.5 million in 2009. The remaining provision of $1.0 million of cash in 2010 was primarily due to a $1.2 million decrease in inventory, a $409,000 decrease in accounts receivable and a $387,000 decrease in other assets which were partially offset by a $603,000 decrease in accrued compensation, restructuring and other current and long term liabilities and a $473,000 decrease in accrued warranty.

During 2009, operating activities used $4.1 million of cash as compared to generating $2.4 million of cash in 2008. Endwave’s net loss from continuing operations, adjusted for depreciation and other non-cash items, was a loss of $7.5 million in 2009 as compared to $375,000 in 2008. The remaining provision of $3.4 million of cash in 2009 was primarily due to a $4.7 million decrease in inventory and a $665,000 increase in accounts payable, which were partially offset by a $767,000 increase in other assets, a $706,000 decrease in accrued warranty and a $462,000 increase in accounts receivable.

During 2010, investing activities used $6.5 million of cash compared to generating $27.9 million of cash in 2009. The use of cash by investing activities in 2010 was primarily due to a net $5.4 million purchase of investments and a purchase of $1.1 million of property and equipment.

During 2009, investing activities provided $27.9 million of cash compared to using $4.1 million of cash in 2008. The source of cash in 2009 was due to the $28.0 million proceeds from the sale of its Defense and Security RF module business and a $600,000 decrease in restricted cash which were partially offset by a purchase of $396,000 of property and equipment and a net $312,000 purchase of investments.

During 2010, financing activities used $36.0 million of cash primarily due to the $36.2 million preferred stock repurchase which was partially offset by $172,000 from the exercise of stock options and $129,000 from the proceeds of stock issuance. In January 2010, Endwave entered into a Stock Purchase Agreement with Oak Investment Partners XI, Limited Partnership, or Oak, pursuant to which it repurchased the 300,000 shares of Endwave Series B Preferred Stock held by Oak for $36.2 million, which included fees and expenses. Such shares

had entitled Oak to a liquidation preference equal to its original investment of $45.0 million before any proceeds from a liquidation or sale of Endwave would have been paid to the holders of Endwave’s common stock.

During 2009, financing activities provided cash of $632,000 as compared to $417,000 in 2008. During 2009, Endwave received $331,000 from the exercise of stock options and $317,000 from the proceeds of stock issuance which was partially offset by capital lease payments.

At December 31, 2010, Endwave had a net unrealized loss of $1,000 related to $16.4 million of investments in twenty-nine debt securities. The decrease in the value of these investments is primarily related to changes in interest rates. The investments all mature during 2011 and Endwave believes that it has the ability and intent to hold these investments until the maturity date. Realized gains were $57,000 in 2008. Realized gains and losses were insignificant for the years ended December 31, 2010 and 2009.

Endwave believes that its existing cash and investment balances will be sufficient to meet its operating and capital requirements for at least the next 12 months. With the exception of operating leases discussed in the notes to the consolidated financial statements included in this proxy statement/prospectus, Endwave has not entered into any off-balance sheet financing arrangements and has not established or invested in any variable interest entities. Endwave have not guaranteed the debt or obligations of other entities or entered into options on non- financial assets. The following table summarizes Endwave’s future cash obligations for operating leases, capital leases and purchase obligations, excluding interest, at December 31, 2010:

Endwave has purchase obligations to certain suppliers. In some cases the products Endwave purchases are unique and have provisions against cancellation of the order. At December 31, 2010, Endwave had approximately $1.4 million of purchase obligations that are due within the following 12 months.

At December 31, 2010, Endwave had $358,000 of other long-term liabilities consisting of a $234,000 long-term liability for restructuring and $124,000 for income taxes.

In January 2010, the Financial Accounting Standards Board, or FASB, issued new standards for fair value measurement and disclosures. These new standards require disclosures for significant transfers in and out of Level 1 and Level 2 fair value measurements and the reasons for the transfers and activity. For Level 3 fair value measurements, purchases, sales, issuances and settlements must be reported on a gross basis. Further, additional disclosures are required by class of assets or liabilities, as well as inputs used to measure fair value and valuation techniques. These standards were required to be adopted in the first quarter of 2010. Endwave adopted these standards, which did not have a material impact on its consolidated financial statements.

In February 2010, the FASB issued new standards that amend the subsequent event disclosure requirements for public company filers. An entity that is an SEC filer is not required to disclose the date through which subsequent events have been evaluated. These standards were effective upon issuance and did not have a material impact on Endwave’s consolidated financial statements.

In July 2010, the FASB issued new standards that amend the receivable disclosure requirements, including the credit quality of financing receivables and the allowance for credit losses. These standards require additional disclosures that will facilitate financial statement user’s evaluation of the nature of credit risk inherent in financing receivables, how that risk is analyzed in arriving at the allowance for credit losses, and the reason for any changes in the allowance for credit losses. These new standards are required to be adopted for interim and annual reporting periods beginning on or after December 15, 2010. Endwave adopted these standards ,which did not have a material impact on its consolidated financial statements.

The following unaudited pro forma condensed combined financial information combines the historical consolidated financial statements of GigOptix and Endwave as if the merger had occurred on the dates specified below.

The following unaudited pro forma condensed combined balance sheet as of December 31, 2010 is based on (i) the historical consolidated balance sheet of GigOptix as of December 31, 2010 and (ii) the historical consolidated balance sheet of Endwave as of December 31, 2010. The following unaudited pro forma condensed combined statement of operations for the year ended December 31, 2010 is based on (i) the historical consolidated statement of operations of GigOptix for the year ended December 31, 2010 and (ii) the historical consolidated statement of operations of Endwave for the year ended December 31, 2010.

The unaudited pro forma condensed combined financial information also reflects the effects of acquiring Endwave for an aggregate estimated consideration of approximately 9.2 million shares of GigOptix common stock based on the closing GigOptix share price of $2.55 on April 28, 2011. If the merger is completed, GigOptix will issue shares of its common stock to holders of Endwave common stock, restricted stock units and in-the-money options. The total number of shares GigOptix will issue to holders of outstanding Endwave in-the-money options is determined by a formula that is based on the closing price of Endwave and GigOptix common stock on the trading day immediately preceding the date the merger is completed. The number of GigOptix shares to be issued to holders of Endwave common stock and Endwave restricted stock units is determined according to a separate formula set forth in the merger agreement. The intent of this formula is for GigOptix to issue a total number of shares in exchange for Endwave common stock and Endwave restricted stock units equal to 42.5% of the outstanding stock of the combined company, minus 42.5% of the number derived from the formula used in calculating the number of the shares of GigOptix common stock to be issued to holders of outstanding Endwave in-the-money options. The specific number of shares of GigOptix common stock to be issued in the merger, as well as the conversion ratio for Endwave shares and the value of the shares GigOptix will issue, cannot be determined until the time the merger is completed because the number of shares of GigOptix common stock and Endwave common stock, restricted stock units and in-the-money options outstanding at the time the merger is completed, and the closing prices of both Endwave’s and GigOptix’ common stock on the trading day immediately prior to the date the merger is completed, cannot be determined until such time.

Pro forma combined adjustments and the assumptions related to the Endwave acquisition were prepared using the purchase method of accounting and are based on the assumption that the acquisition of Endwave took place as of December 31, 2010 for purposes of the pro forma condensed combined balance sheet and January 1, 2010 for purposes of the pro forma condensed combined statement of operations.

In accordance with the purchase method of accounting, the actual consolidated financial statements of GigOptix will reflect the Endwave acquisition only from and after the date of acquisition. GigOptix has not yet undertaken any detailed analysis of the fair value of Endwave’s assets and liabilities and will not finalize the purchase price allocation related to the Endwave acquisition until after the merger is consummated. As such, the following pro forma condensed combined balance sheet includes balances for Endwave as of December 31, 2010 without any adjustments to reflect the fair value of the balances as would be required with the purchase method of accounting.

For purposes of the pro forma condensed combined financial information, adjustments for estimated transaction and integration costs for the Endwave acquisition have been excluded. These aggregate estimated transaction costs are expected to be approximately $2.4 million and include estimated costs associated with investment banker advisory fees and legal fees of both companies. In addition, the combined company will incur integration costs related to system conversions and certain employee-related severance costs. The specific details of these integration plans will continue to be refined over the next couple of quarters.

The unaudited pro forma condensed combined financial information included herein does not give effect to any potential cost reductions or other operating efficiencies that could result from the Endwave acquisition, including but not limited to those associated with potential (i) reductions of corporate overhead, (ii) eliminations of duplicate functions and (iii) increased operational efficiencies through the adoption of best practices and capabilities from each company.

The pro forma condensed combined financial information has been prepared in accordance with the rules and regulations of the SEC. The pro forma condensed combined financial information is presented for illustrative purposes only and is not necessarily indicative of the combined operating results or financial position that would have occurred if such transactions had been consummated on the dates and in accordance with the assumptions described herein, nor is it necessarily indicative of future operating results or financial position.

You are urged to read the pro forma condensed combined financial information below together with GigOptix’ and Endwave’s historical consolidated financial statements and accompanying notes, included elsewhere in this proxy statement/prospectus.

See accompanying notes to unaudited pro forma condensed combined financial information.

The following preliminary allocation of the Endwave purchase price is based on GigOptix’ preliminary estimates of the fair value of the tangible and intangible assets and liabilities of Endwave as of December 31, 2010. The final determination of the allocation of the purchase price will be based on the fair value of such assets and liabilities as of the actual consummation date of the acquisition and will be completed after the acquisition is consummated. Such final determination of the purchase price allocation may be different than the preliminary estimates used in these pro forma condensed combined financial statements.

The estimated purchase price of Endwave (as calculated in the manner described above) is allocated to the assets to be acquired and liabilities to be assumed based on the following preliminary basis as of December 31, 2010 (amounts in thousands):

The following pro forma combined adjustments have been reflected in the unaudited pro forma condensed combined financial information. These adjustments give effect to pro forma events that are (i) directly attributable to the Endwave merger, (ii) factually supportable and (iii) with respect to the statement of operations, expected to have continuing impact on the combined company.

All adjustments are based on current assumptions and are subject to change upon completion of the final purchase price allocation based on the intangible assets and liabilities of Endwave at the merger closing date.

(A) To reflect the elimination of Endwave’s stockholders’ equity balances as of December 31, 2010 and to reflect the issuance of 9.2 million shares of GigOptix common stock (valued at $23.4 million for purposes of this pro forma combined information based on the GigOptix stock price on April 28, 2011) as consideration delivered to acquire Endwave.

(B) To reflect the expense associated with the estimated negative goodwill. For purposes of the pro forma financial statements, it was assumed that the amount of estimated identifiable intangible assets was zero and that the full $4.9 million related to negative goodwill. Therefore, there were no adjustments to the pro forma condensed combined balance sheet related to intangible assets and no adjustments to the pro forma condensed combined statement of operations related to the amortization of intangible assets.

(C) To reflect (i) the elimination of Endwave’s basic common shares outstanding, net of (ii) the assumed issuance of basic common shares as a result of the transaction, assuming this transaction occurred at the beginning of the period.

For purposes of preparing these pro forma condensed combined financial statements, the fair value of Endwave’s inventory, accounts receivable and property, plant and equipment were estimated to approximate their carrying value on the date of acquisition. To the extent that the final purchase price allocation causes GigOptix’ cost of revenue, depreciation and amortization expense to differ from the amount presented in the accompanying pro forma condensed combined statement of income information, earnings per common share will be affected.

This section contains information about the special meeting of Endwave stockholders that has been called to adopt the merger agreement and approve the adjournment proposal. This proxy statement/prospectus is being furnished to Endwave stockholders in connection with the solicitation of proxies by the Endwave board of directors to be used at the special meeting. Endwave is first mailing this proxy statement/prospectus and enclosed proxy card on or about May 18, 2011.

A special meeting of the Endwave stockholders will be held on June 17, 2011, starting at 8:00 a.m., local time (unless it is adjourned or postponed to a later date) at Endwave’s offices at 130 Baytech Drive, San Jose, California 95134.

The purpose of the special meeting is for Endwave stockholders to consider and vote upon proposals to adopt the merger agreement and approve the potential adjournment of the special meeting.

The Endwave board of directors unanimously recommends that Endwave stockholders vote “FOR” the adoption of the merger agreement and “FOR” the adjournment proposal.

As discussed elsewhere in this document, at a meeting duly called and held, the Endwave board of directors has (i) unanimously determined that the merger agreement and the transactions contemplated thereby are fair to, advisable and in the best interests of the Company’s stockholders, (ii) unanimously approved and adopted the merger agreement and the transactions contemplated thereby and (iii) unanimously resolved to recommend adoption of the merger agreement by the stockholders of Endwave.

Endwave stockholders should carefully read this document in its entirety for more detailed information concerning the merger agreement. In particular, Endwave stockholders are directed to the merger agreement, which is attached hereto as Annex A.

The Endwave board has chosen the close of business on May 12, 2011 as the record date that will determine the stockholders who are entitled to receive notice of, and to vote at, the special meeting or at any adjournment or postponement of the special meeting. Only holders of record at the close of business on the record date are entitled to vote at the special meeting. At the close of business on the record date, there were 9,936,754 shares of Endwave common stock outstanding, held by approximately 78 holders of record. A list of the names of Endwave stockholders of record will be available at the special meeting and for 10 days prior to the special meeting for any purpose related to the special meeting during regular business hours at Endwave’s principal executive offices located at 130 Baytech Drive, San Jose, California 95134. Each holder of shares of Endwave common stock outstanding on the record date will be entitled to one vote for each share held of record upon each matter properly submitted at the special meeting and at any adjournment or postponement of the special meeting.

In order for Endwave to satisfy its quorum requirements, the holders of a majority of the total number of outstanding shares of Endwave common stock entitled to vote at the special meeting must be present in person or represented by proxy. Shares of Endwave common stock represented at the meeting but not voted, including shares for which proxies have been received but for which stockholders have abstained on either or both of the

matters, will be treated as present at the special meeting for purposes of determining the presence or absence of a quorum. “Broker non-votes” will also be counted for the purpose of determining a quorum at the special meeting. In the event that a quorum is not present at the special meeting, it is expected that the special meeting will be adjourned or postponed to solicit additional proxies.

Abstentions will be counted towards the vote total for each proposal, and will have the same effect as “Against” votes. Broker non-votes have no effect and will not be counted towards the vote total for any proposal.

If you are the beneficial owner of shares held by a broker, bank or other agent as your nominee, please follow the instructions given by your broker to vote included with these proxy materials, or to vote in person at the annual meeting, request a valid proxy from your agent. If you do not give any voting instructions to your agent, your agent can vote your shares with respect to “discretionary” items, but not with respect to “non-discretionary” items. Discretionary items are proposals considered “routine” under the rules of the New York Stock Exchange, or NYSE, on which your agent may vote shares held by it in the absence of your voting instructions. Non-discretionary items are proposals considered “non-routine” under the rules of the NYSE, including those involving a contest or a matter that may substantially affect the rights or privileges of stockholders, such as mergers or stockholder proposals. On non-discretionary items for which you do not give your agent instructions, the shares will be treated as broker non-votes.

If you are a record holder of shares of Endwave common stock, you may submit your proxy, or vote, in either of the following ways:

All shares of Endwave common stock entitled to vote and represented by properly completed proxies received prior to the special meeting and not properly revoked, will be voted at the special meeting as instructed on the proxies. If Endwave stockholders submit a properly completed proxy but do not indicate how their shares of Endwave common stock should be voted on a matter, the shares of Endwave common stock represented by their properly completed proxy will be voted as the Endwave board recommends and therefore, FOR the adoption of the merger agreement and FOR the adjournment proposal. Proxy materials are available at https://materials.proxyvote.com/29264A.

If you are the record holder of your shares, you may revoke your proxy in any one of three ways:

If your shares are held by your broker, bank or other agent as a nominee, you should follow the instructions provided by your broker, bank or other agent.

Although it is not currently expected, the special meeting may be adjourned or postponed for the purpose of soliciting additional proxies. Any adjournment may be made without notice, other than by an announcement made at the special meeting of the time, date and place of the adjourned meeting. For the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies if there is an insufficient number of votes at the time of such adjournment to adopt the merger agreement, you may vote FOR, AGAINST or ABSTAIN. Any signed proxies received by Endwave for which no voting instructions are provided on such matter will be voted FOR the adjournment proposal. Any adjournment of the special meeting for the purpose of soliciting additional proxies will allow Endwave stockholders who have already sent in their proxies to revoke them at any time prior to their use at the special meeting as adjourned.

Endwave will pay for the entire cost of soliciting proxies. In addition to these proxy materials, Endwave’s directors and employees may also solicit proxies in person, by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. Endwave may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.

The discussion in this proxy statement/prospectus of the merger and the principal terms of the merger agreement is subject to, and is qualified in its entirety by reference to, the merger agreement, a copy of which is attached to this proxy statement/prospectus as Annex A and is incorporated into this proxy statement/prospectus by reference.

Under the terms of the merger agreement, Merger Sub will be merged with and into Endwave. As a result of the merger, the separate corporate existence of Merger Subsidiary will cease and Endwave will survive as a wholly-owned subsidiary of GigOptix.

Upon consummation of the merger, GigOptix will issue shares of its common stock to holders of Endwave common stock, restricted stock units and in-the-money options. The total number of shares GigOptix will issue to holders of outstanding Endwave in-the-money options is determined by a formula that is based on the closing price of Endwave and GigOptix common stock on the trading day immediately preceding the date the merger is completed. The intent of this formula is to give the holders of Endwave options GigOptix shares with a market value approximately equal to the “spread value” of such options. “Spread value” is the product of the total number of shares subject to the option and the difference between the closing price of Endwave’s common stock on the Nasdaq Global Market on the trading day prior to the effective time of the merger and the option’s per share exercise price. Holders of Endwave stock options that are not in-the-money will not be entitled to receive any shares of GigOptix common stock for those stock options. We believe that treating options in this manner compensates the optionholders for the current realizable value of their options but prevents any future dilution to the holders of Endwave and GigOptix stock that would result if such options were assumed by GigOptix.

In addition, Endwave restricted stock units and options to acquire Endwave common stock outstanding immediately prior to the consummation of the Merger will be converted into shares of GigOptix common stock based on formulas contained in the merger agreement and as described under “The Merger Agreement—Treatment of Endwave Stock Options” and “The Merger Agreement—Treatment of Restricted Stock Units” beginning on page 164 of this proxy statement/prospectus such that following the merger, the pre-merger holders of common stock and restricted stock units of Endwave will own approximately 42.5% of the combined company, less 42.5% of the shares issued in the merger in respect of Endwave stock options.

The board of directors of each of Endwave and GigOptix has from time to time engaged with senior management of its respective company in reviews and discussions of potential strategic alternatives, and has considered ways to enhance each company’s performance and prospects in light of competitive and other relevant developments. These reviews have included periodic discussions with regard to potential transactions that would further the company’s strategic objectives and the potential benefits and risks of those transactions.

In 2008 and 2009, senior executives of GigOptix and Endwave met periodically to discuss their respective companies and potential strategic relationships between GigOptix and Endwave, but none of these discussions progressed beyond the preliminary stage.

In April 2009, Endwave sold its defense and homeland security business to Microsemi Corporation.

In late 2009, Endwave explored the possible sale of its remaining telecommunications business assets to a non-U.S. microwave and millimeterwave component and sub-system supplier, which we refer to as Party A. Party A’s offer, which was subject to Party A’s satisfactory completion of a “due diligence” review and negotiation of a mutually-agreeable asset purchase agreement, was to purchase such assets for approximately $6,000,000 in cash, and to assume only certain specified Endwave liabilities. The transaction would have necessitated a post-closing liquidation of Endwave in which Endwave would not be able to distribute cash to any of its stockholders until satisfaction of Endwave’s retained liabilities. The Endwave board of directors, after considering the risks and merits of the proposed transactions, determined that it was in the best interest of Endwave’s stockholders not to proceed with the proposed transactions.

On January 27, 2010, Dr. Katz sent an email to John Mikulsky, Endwave’s President and Chief Executive Officer, and suggested to meet and discuss prospects of mutual interest. On February 9, 2010, the email sent by Dr. Katz to Mr. Mikulsky was forwarded to a representative of Merriman. In response, the representative of Merriman contacted Dr. Katz and the two met on February 11, 2010 to discuss potential strategic relationships between GigOptix and Endwave, including interest in a merger or acquisition transaction.

On March 5, 2010, Mr. Mikulsky and a representative of Merriman met with Dr. Katz in person. At this meeting, Dr. Katz expressed an interest in a strategic combination of GigOptix and Endwave.

On July 1, 2010, the Endwave board of directors held a meeting at which all members of the Endwave board of directors were present. A representative of Merriman and a representative of Cooley LLP, or Cooley, Endwave’s outside counsel, were also present. At such meeting, Endwave management reported to the Endwave board of directors on recent developments in Endwave’s business, including recent declines in sales of radio module products to Endwave’s largest customer. The Endwave board of directors then engaged in a discussion of Endwave’s strategic alternatives to address the business developments outlined by management. As a part of such discussion, a representative of Cooley advised the Endwave directors of their fiduciary duties in pursuing a potential sale of Endwave. After discussion, the Endwave board of directors authorized management and Merriman to pursue discussions with potential strategic partners.

From July 2010 through September 2010, Endwave and Merriman contacted approximately 30 companies that had been identified by Endwave and Merriman as potentially interested in an acquisition of or by Endwave. During this process, of the companies contacted, only GigOptix, Party A and a company that is referred to in this proxy statement/prospectus as Party B engaged in discussions with Endwave that progressed beyond the preliminary stages.

As a part of this process, on July 12, 2010, a representative of Merriman contacted Dr. Katz by telephone to inquire as to whether GigOptix continued to be interested in a potential strategic transaction with Endwave.

On July 21, 2010, the Endwave board of directors held its regular quarterly in-person board meeting at which all members of the board of directors, members of Endwave management, a representative of Merriman and a representative of Cooley were present. At that meeting, a Merriman representative reported to the board of directors on the status of its contacts with the potential strategic partners discussed at the July 1 board of directors meeting.

On August 11, 2010, the Endwave board of directors held a telephonic board meeting at which all members of the board of directors, Curt Sacks, Endwave’s Chief Financial Officer, a representative of Merriman and a representative of Cooley were present. At that meeting, Merriman’s representative reported to the board of directors on Endwave’s discussions with potential strategic partners.

On September 23, 2010, a representative of Merriman and Dr. Katz met in person to discuss a potential strategic combination of Endwave and GigOptix.

On September 28, 2010, Mr. Ron Shelton, who was then GigOptix’ Chief Financial Officer, contacted Wade Meyercord, Endwave’s Chairman of the Board, to encourage Endwave to consider a strategic combination with GigOptix.

On October 2, 2010, Mr. Mikulsky met with representatives of Party A to discuss Party A’s level of interest in a potential strategic transaction with Endwave.

On October 15, 2010, Mr. Mikulsky, a representative of Merriman and Dr. Katz met in GigOptix’ offices, and Dr. Katz presented a potential acquisition scenario.

On October 20, 2010, the Endwave board of directors held its regular quarterly in-person board meeting at which all members of the board of directors, members of Endwave management, a representative of Merriman and a representative of Cooley were present. At that meeting, Merriman’s representative reported to the board of directors on the status of Endwave’s discussions with potential strategic partners.

On October 22, 2010, Mr. Mikulsky, a representative of Merriman and Dr. Katz met in person to discuss Endwave’s and GigOptix’ respective business and whether there was a strategic fit between Endwave and GigOptix.

On October 25, 2010, Dr. Katz sent a representative of Merriman an email indicating GigOptix’ desire to move forward with discussions regarding a potential combination of Endwave and GigOptix. In a subsequent email to Merriman’s representative that day, Dr. Katz outlined a potential schedule for review of each company’s financial projections and GigOptix’ submission of a nonbinding letter of intent setting forth the terms on which GigOptix would be prepared to negotiate a definitive merger agreement.

On November 2, 2010, Mr. Mikulsky and a representative of Merriman met with a representative of Party B to discuss Party B’s level of interest in a potential strategic transaction with Endwave.

On November 11, 2010, Mr. Sacks, Mr. Shelton and a representative of Merriman met in person to review each company’s financial projections for fiscal years 2010 through 2012.

On November 18, 2010 and November 19, 2010, Mr. Mikulsky, Mr. Sacks and a representative from Merriman met in person with representatives of Party A.

On November 24, 2010, Mr. Mikulsky, Dr. Katz and a representative of Merriman met in person to discuss the potential benefits of a stock-for-stock merger between Endwave and GigOptix.

On November 29, 2010, the GigOptix board of directors held a meeting at which all members of the GigOptix board of directors were present. A representative of Nixon Peabody LLP, or Nixon Peabody, GigOptix’ outside counsel, was also present. At such meeting, GigOptix management reported to the GigOptix board of directors on the discussions held to date regarding a potential stock-for-stock merger between Endwave and GigOptix. The GigOptix board of directors discussed the possibility of a combination of the two companies, and authorized management of GigOptix to present a nonbinding letter of intent for a stock-for-stock merger in which Endwave’s stockholders would receive approximately 50% of the outstanding shares of the combined company. After the meeting of the GigOptix board of directors, Dr. Katz sent Mr. Mikulsky such nonbinding letter of intent.

On December 2, 2010, Party A sent a non-binding indication of interest to a representative of Merriman reiterating Party A’s interest in proceeding with an asset purchase transaction as originally discussed in late 2009. This indication of interest was forwarded by Merriman’s representative to Mr. Mikulsky and Mr. Sacks. The indication of interest made it clear that, in light of Endwave’s decreased forecasts as compared to those in late 2009, the purchase price to be paid by Party A would have been less than the $6,000,000 offered in 2010.

On December 7, 2010, a representative of Merriman provided Endwave’s board of directors with a status report on Endwave’s meetings with various potential strategic partners, in which GigOptix was identified as the only company that had been identified as interested in pursuing an acquisition of all of Endwave’s outstanding stock. Merriman’s representative reviewed the terms of the letter of intent and compared and contrasted them with the terms discussed with Party A in late 2009.

On December 9, 2010, Endwave received a decreased revenue forecast from its largest customer, as well as a telephone inquiry from a U.S. microwave and millimeterwave sub-system supplier, which we refer to as Party B, regarding a potential stock-for-stock merger.

On December 14, 2010, Endwave sent revised financial projections to GigOptix and Party B.

On December 15, 2010, Dr. Katz met with all members of the Endwave board of directors in person. Earlier that day, a financial advisor to Party B had contacted Merriman’s representative by telephone outlining the terms on which Party B would be willing to acquire Endwave. Party B’s initial offer, which was subject to Party B’s satisfactory completion of a “due diligence” review and negotiation of a mutually-agreeable merger agreement, would have entailed the issuance of shares of Party B common stock to Endwave’s stockholders having a value of approximately $15 million as of such date.

On December 16, 2010, Mr. Mikulsky met with the Chief Executive Officer of Party B in person to discuss a potential strategic combination of Endwave and Party B in view of Endwave’s revised financial projections. That same day, the GigOptix board of directors held a meeting at which all members of the GigOptix board of directors were present. A representative of Nixon Peabody was also present. At such meeting, GigOptix management reported to the GigOptix board of directors on the revised financial projections that Endwave had provided to GigOptix, as well as the meeting between Dr. Katz and the members of the Endwave board of directors. The GigOptix board of directors discussed revising the terms set forth in the nonbinding letter of intent to reduce the number of shares in the combined company that Endwave’s stockholders would receive to 40% of the outstanding shares of the combined company. Following the meeting of the GigOptix board of directors, Dr. Katz sent Mr. Mikulsky a revised nonbinding letter of intent providing for a stock-for-stock merger in which Endwave’s stockholders would receive approximately 40% of the outstanding shares of the combined company, with the reduction attributable to Endwave’s reduced revenue forecast.

On December 17, 2010, Mr. Shelton sent revised financial projections to Endwave.

On December 20, 2010, the Endwave board of directors held a telephonic meeting at which all members of the Endwave board of directors other than John McGrath, Mr. Sacks, a representative of Merriman and a representative of Cooley were present. Merriman’s representative reported to the board of directors regarding Endwave’s negotiations with GigOptix and Party B. The Endwave board of directors engaged in a full discussion of the risks and merits of the proposed transaction with GigOptix and Party B, as well as of Endwave as a stand-alone company. After full discussion, the Endwave board of directors determined that the proposed transaction with GigOptix was likely to be more advantageous to Endwave’s stockholders than the proposed transaction with Party B or Endwave remaining as a stand-alone company, and accordingly directed Endwave management to proceed with its negotiations.

On December 23, 2010, Party B’s financial advisor contacted a representative of Merriman by telephone to convey revised terms on which Party B would be willing to acquire Endwave in a stock-for-stock merger transaction. Party B’s revised offer, which was subject to Party B’s satisfactory completion of a “due diligence” review and negotiation of a mutually-agreeable merger agreement, would have entailed the issuance of shares of Party B common stock to Endwave’s stockholders having a value of approximately $19 million as of such date.

On December 28, 2010, Dr. Katz contacted a representative of Merriman by telephone to indicate GigOptix’ willingness to increase the number of shares to be issued to Endwave’s stockholders from approximately 40% of the outstanding shares of the combined company to approximately 45% of the outstanding shares of the combined company.

The Endwave board of directors held a series of telephonic meetings on December 28, 29 and 30, 2010, at which all members of the Endwave board of directors, Mr. Sacks, a representative of Merriman and a representative of Cooley were present. During this series of meetings, Merriman’s representative made a presentation to the Endwave board of directors comparing the risks and merits of Endwave remaining as a stand-alone company, engaging in the potential transaction with GigOptix, engaging in the potential transaction with Party B, or selling its assets to Party A on the terms discussed in 2009. The Endwave board of directors engaged in full discussions of the risks and merits of the possible transactions, as well as of Endwave as a stand-alone company. After these discussions, the Endwave board of directors determined that the proposed transaction with GigOptix was likely to be more advantageous to Endwave’s stockholders than the proposed transaction with Party B or Endwave remaining as a stand-alone company and directed Endwave management to enter into a nonbinding letter of intent with GigOptix on the terms conveyed by Dr. Katz on December 28, 2010.

On December 30, 2010, Dr. Katz communicated with each of the members of the GigOptix board of directors that additional discussions had been held with Endwave’s management and a representative of Merriman regarding increasing the number of shares to be issued to Endwave’s stockholders from approximately 40% of the outstanding shares of the combined company to approximately 45% of the outstanding shares of the combined company. After discussions between the members of the GigOptix board of directors, it was decided that Dr. Katz should send a revised nonbinding letter of intent providing for a stock-for-stock merger in which Endwave’s stockholders would receive approximately 45% of the outstanding shares of the combined company, and providing further that the merger would be conditioned on Endwave maintaining a minimum but unspecified level of cash and working capital at closing. Later that day, Dr. Katz sent such revised nonbinding letter of intent to a representative of Merriman, signed by GigOptix.

On December 31, 2010, Endwave and GigOptix entered into the nonbinding letter of intent in the form most recently proposed by GigOptix.

During the month of January 2011, Endwave and GigOptix and their respective financial and legal advisors conducted mutual “due diligence” reviews and negotiated the terms and conditions set forth in a draft merger agreement prepared by Nixon Peabody, including, among other things, whether there would be any closing conditions or purchase price adjustments with regard to Endwave’s or GigOptix’ cash or working capital at closing and the treatment of Endwave options and restricted stock units.

On January 27, 2011, the GigOptix board of directors held a meeting at which all members of the GigOptix board of directors and a representative of Nixon Peabody were present. GigOptix management reported to the GigOptix board of directors on the status of the ongoing negotiations, including outstanding issues with regard to the percentage of the number of shares that Endwave’s stockholders would received in the combined company, closing conditions or purchase price adjustments with regard to Endwave’s or GigOptix’ cash or working capital at closing and the treatment of Endwave options and restricted stock units. The GigOptix board of directors directed the GigOptix management in accordance with its views on these outstanding issues.

On January 27 and 28, 2011, GigOptix and Endwave and their respective financial and legal advisors continued to negotiate the terms and conditions of the merger as set forth in the draft merger agreement. It was ultimately negotiated that there would be no purchase price adjustment or closing conditions relating to either company’s cash or working capital, but the number of shares to be issued to Endwave’s stockholders would be reduced to account for Endwave’s cash and working capital at closing being significantly lower than GigOptix had anticipated. Specifically, the merger agreement was revised between January 28, 2011 and February 3, 2011 to provide that upon consummation of the merger, the outstanding shares of Endwave common stock (other than shares subject to perfected appraisal rights and other than shares held by Endwave, Merger Sub, GigOptix or any subsidiary of GigOptix), including shares issued upon settlement of all outstanding restricted stock units to acquire Endwave common stock, would be converted into the right to receive an aggregate number of shares of GigOptix common stock equal to the product of (0.425/0.575) and the number of shares of GigOptix common stock outstanding immediately prior to consummation of the merger, less 42.5% of the shares of GigOptix common stock to be issued to holders of options to acquire Endwave common stock in the merger.

On February 3, 2011, the GigOptix board of directors held a meeting at which all members of the GigOptix board of directors, a representative of Roth (which was engaged only in the capacity of rendering a fairness opinion to the GigOptix board of directors, and was not an advisor on the transaction) and a representative of Nixon Peabody were present. In that meeting, the representative of Roth presented its financial analysis and delivered Roth’s oral opinion to the GigOptix board of directors (which opinion was confirmed in writing by delivery of Roth’s written opinion dated February 4, 2011) as to the fairness of the merger consideration to the holders of GigOptix stock, from a financial point of view, based upon and subject to the assumptions made, procedures followed, matters considered and limitations on the scope of the review undertaken by Roth in rendering its opinion. The representative of Nixon Peabody provided the GigOptix board of directors with a detailed summary of the most recent draft of the proposed merger agreement, reminded the board members of their fiduciary duties in the context of the proposed merger, and reviewed the matters proposed to be approved by the GigOptix board of directors, including increasing the size of the board and electing John Mikulsky and Joseph Lazzara to become members of the GigOptix board of directors at the closing of the merger. The GigOptix board of directors discussed the proposed merger, and unanimously (i) determined that the merger agreement and the transactions contemplated thereby are fair to and in the best interest of GigOptix and its stockholders, (ii) deemed it advisable to enter into the merger agreement and to proceed with the merger, (iii) approved the execution, delivery and performance of the merger agreement and the transactions contemplated thereby, including the merger, and (iv) increased the size of the board to seven members, with vacancies in Class I and Class II of the GigOptix board of directors and elected John Mikulsky and Joseph Lazzara, subject to the consummation of the merger, to serve on the GigOptix board of directors, effective as of the effective time of the merger.

On February 4, 2011, the Endwave board of directors held a meeting at which all members of the Endwave board of directors, representatives of Merriman and a representative of Cooley were present. In that meeting:

Later that same day, Endwave, GigOptix and Merger Subsidiary executed the merger agreement.

On February 7, 2011, GigOptix issued a joint press release announcing the transaction and the execution of the merger agreement.

GigOptix’ board of directors believes that the merger agreement and the merger are fair to and in the best interests of GigOptix and its stockholders. Accordingly, GigOptix’ board of directors unanimously approved the merger and the merger agreement at a meeting held on February 3, 2011.

In reaching its decision to approve the merger, GigOptix’ board of directors, with the assistance of its financial and legal advisers, considered and analyzed a number of factors, including those reviewed by GigOptix’ board of directors at the meetings described above. The following were the material factors that GigOptix’ board of directors considered in determining to approve the merger agreement and the merger:

GigOptix’ board of directors also considered a number of potentially negative factors, including those listed below:

The foregoing list comprises the material factors considered by GigOptix’ board of directors in its consideration of the merger and is a summary and not intended to be an exhaustive list. In view of the variety of factors and information considered in connection with the evaluation of the merger, GigOptix’ board of directors did not consider it practicable to, and did not attempt to, quantify or otherwise assign relative weights or values to the specific factors considered in reaching its decision. Rather, the decision was made after an overall analysis and consideration of all of the factors as a whole. In addition, individual members of GigOptix’ board of directors may have given different weights to different factors. There can be no assurance that the benefits of the potential growth, synergies or opportunities considered by GigOptix’ board of directors will be achieved through consummation of the merger. Instead, this explanation of GigOptix’ reasons for the merger and other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors described under the heading “Special Cautionary Note Regarding Forward-Looking Statements” on page 198 of this proxy statement/prospectus.

In evaluating the merger, the Endwave board of directors consulted extensively with Endwave’s management and financial and legal advisors and considered a number of alternatives to enhance Endwave’s competitive position in the markets it serves and to increase stockholder value. Of such alternatives, the Endwave board of directors believes the proposed merger is in the best interest of Endwave and its stockholders. The Endwave board of directors’ decision to approve the merger agreement and the merger and to recommend to Endwave’s stockholders that they vote for the adoption of the merger agreement was based on a number of factors. These factors included the following:

The Endwave board of directors considered the current and historical financial condition and results of operations and anticipated future performance of Endwave, as well as the risks and uncertainties associated with continuing to operate Endwave as a stand-alone company, including the following:

The Endwave board of directors also considered the possibility of Endwave being acquired by another company and the risks and uncertainties associated with any such alternative acquisition, including the following:

The analyses and presentations by Endwave management regarding the business, operations, sales, management and competitive position of Endwave and forecasts regarding profitability under various scenarios.

The Endwave board of directors considered their expectations that the merger would result in a larger, more competitive combined company, better positioned to compete in the markets served by the combined company. The Endwave board of directors also considered the benefits of a broader product portfolio and customer base, operational cost savings and scale that would accrue to the combined company and also considered that the opportunities for strategic investment, customer expansion and new growth would be significantly greater for the combined company compared to what Endwave would likely achieve as a stand-alone company.

The Endwave board of directors considered the opportunity for Endwave’s stockholders to participate in the potential appreciation of the common stock of the combined company, in light of the perceived benefits of the merger of creating a more competitive and efficient company. The Endwave board of directors also determined that, while the conversion ratio in the merger agreement was not likely to give rise to the Endwave stockholders receiving any meaningful premium to Endwave’s recent common stock trading prices, the shares to be received by the Endwave stockholders in the merger are much more likely to appreciate in value over time than the shares of Endwave common stock and the consideration offered by Party A and Party B.

The Endwave board of directors considered the financial analysis by Merriman, Endwave’s financial advisor, of the proposed consideration and the opinion of Merriman, dated February 4, 2011, to the effect that, as of that date, and based upon and subject to the various considerations set forth in its opinion, the consideration to be received by holders of Endwave common stock pursuant to the merger agreement was fair, from a financial point of view, to such holders.

The Endwave board of directors considered the terms and conditions of the merger agreement, including but not limited to the following:

The Endwave board of directors also identified and considered a number of uncertainties, risks and other potentially negative factors in its consideration of the merger and merger agreement, including but not limited to the following:

The foregoing list comprises the material factors considered by Endwave’s board of directors in its consideration of the merger and is a summary and not intended to be an exhaustive list. In view of the variety of factors and information considered in connection with the evaluation of the merger, Endwave’s board of directors did not consider it practicable to, and did not attempt to, quantify or otherwise assign relative weights or values to the specific factors considered in reaching its decision. Rather, the decision was made after an overall analysis and consideration of all of the factors as a whole. In addition, individual members of Endwave’s board of directors may have given different weights to different factors. There can be no assurance that the benefits of the potential growth, synergies or opportunities considered by Endwave’s board of directors will be achieved through consummation of the merger. Instead, this explanation of Endwave’s reasons for the merger and other

information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors described under the heading “Special Cautionary Note Regarding Forward-Looking Statements” on page 49 of this proxy statement/prospectus.

Merriman was retained to act as financial advisor to Endwave in connection with the merger and, if requested, to render to the board of directors of Endwave an opinion as to the fairness, from a financial point of view, of the consideration to be received by Endwave stockholders in the merger. The merger consideration was determined through arm’s length negotiations between Endwave and GigOptix and not by Merriman, although Merriman assisted Endwave in these negotiations.

At the February 4, 2011 meeting of Endwave’s board of directors, Merriman delivered its oral opinion, subsequently confirmed in writing as of the same date, to Endwave’s board of directors to the effect that, as of the date of such opinion, based upon and subject to the assumptions made, matters considered and limits of the review undertaken by Merriman, the merger consideration was fair, from a financial point of view, to the holders of the outstanding shares of Endwave common stock.

The complete text of Merriman’s written opinion, dated February 4, 2011, which sets forth, among other things, the assumptions made, matters considered and limits on the review undertaken by Merriman in connection with its opinion, is attached as Annex B to this proxy statement/prospectus and is incorporated herein by reference. Merriman provided its opinion for the information and assistance of Endwave’s board of directors in connection with its consideration of the merger. Merriman’s opinion is not a recommendation as to how any holder of shares of Endwave common stock should vote with respect to the merger or any other matter. Endwave stockholders are urged to read Merriman’s opinion in its entirety. The summary of Merriman’s opinion set forth in this proxy statement/prospectus is qualified in its entirety by reference to the full text of Merriman’s opinion.

In connection with Merriman’s role as financial advisor to Endwave, and in arriving at its opinion, Merriman has, among other things:

In Merriman’s review and analysis and in arriving at its opinion, Merriman has relied upon, without any independent verification or liability therefore, the accuracy and completeness of all of the financial and other information that was publicly available or supplied or otherwise made available to Merriman by or on behalf of Endwave, and upon the assurances of the management of Endwave that no relevant information has been omitted or remains undisclosed to Merriman. Merriman has also relied upon the management of Endwave as to the reasonableness of the assumptions, and bases therefore, of the financial and operating projections provided to Merriman. Merriman also has held discussions with members of the management of Endwave regarding their views with respect to a number of risks and uncertainties associated with projections provided to Merriman. Merriman has not been engaged to assess the reasonableness of such projections, of the timeframe for achieving them or of the assumptions on which they were based. Merriman expresses no view as to such projections or assumptions. Merriman has assumed that they have been reasonably prepared based on assumptions reflecting the best current available estimates and judgments by managements of Endwave and GigOptix as to the expected future results of operations and financial condition of Endwave and GigOptix to which such analyses or forecasts relate.

In preparing its opinion, Merriman performed a variety of financial and comparative analyses. The following is a summary of the material financial analyses presented by Merriman to Endwave’s board of directors in connection with rendering its opinion. The following summary, however, does not purport to be a complete description of the financial analyses performed by Merriman and is qualified in its entirety by reference to the full text of its opinion. Some of the financial analyses summarized below include information presented in tabular format. The tables must be read together with the full text of each summary and alone are not a complete description of Merriman’s financial analyses.

Merriman reviewed combined operating results for the calendar year ended December 31, 2010, projected calendar year 2011 and 2012 and combined balance sheet data as of December 31, 2010 and analyzed the relative contribution of each of Endwave and GigOptix. In calculating the relative contribution, Merriman used financial forecasts prepared by Endwave management and GigOptix management and assumed no cost savings or other synergies. Merriman reviewed the contributions to revenues, gross profit, cash and cash equivalents net of debt, total tangible assets and stockholders’ equity. This analysis indicated that Endwave would contribute the percentages shown in the following table:

The results of this analysis are not necessarily indicative of the contributions that the respective businesses may have in the future.

Based on the merger consideration defined in the merger agreement, an assumed Endwave stock price of $2.25 on February 4, 2011, an assumed GigOptix stock price of $2.50 on February 4, 2011 and using the treasury

stock method to calculate the numbers of shares of GigOptix common stock outstanding after taking into account outstanding options and warrants, Endwave’s stockholders will own approximately 39.1% of GigOptix after the merger.

Merriman compared certain financial information and commonly used valuation measurements for Endwave to corresponding information and measurements for a group of seven publicly traded small and medium size wireless communications-related communications companies, consisting of Alvarion Ltd, Aviat Networks, Inc., Ceragon Networks Ltd., DragonWave Inc., Filtronic plc, Frequency Electronics Inc., and RF Monolithics Inc., which are collectively referred to in this discussion as the Selected Companies. This financial information and valuation measurements included, among other things the ratio of common equity market value as adjusted for debt and cash, which is referred to in this discussion as Enterprise Value, to revenues. Endwave did not have positive earnings per share so it was not possible to utilize that measure of financial performance. Merriman calculated multiples for the selected companies based on the closing stock prices for those companies as of February 3, 2011.

Based upon the proposed merger consideration, the implied enterprise value of Endwave on February 3, 2011 was approximately $300,000. As a result, the implied multiple of enterprise value to revenue rounds to zero for all periods.

None of the Selected Companies is identical to Endwave. Accordingly, Merriman believes the analysis of publicly traded comparable companies is not simply mathematical. Rather, it involves complex considerations and qualitative judgments, which are reflected in Merriman’s opinion, concerning differences in financial and operating characteristics of the Selected Companies and other factors that could affect the public trading value of the Selected Companies.

Merriman reviewed the financial terms, to the extent publicly available, of 10 merger and acquisition transactions that it deemed comparable to the transaction between Endwave and GigOptix, which are referred to in this discussion as the Selected Precedent Transactions. Merriman selected these transactions by searching SEC filings, news stories, press releases, industry and popular press reports, databases and other sources and by applying the following criteria:

For each of the Selected Precedent Transactions, Merriman calculated and compared transaction value as a multiple of latest twelve months revenue and next twelve months revenues relative to the completion date. Endwave did not have positive operating income or net income, so no attempt was made to utilize those measures of financial performance. The range of values calculated is set forth in the following table:

By way of comparison, the implied enterprise value of Endwave on February 3, 2011 was approximately $300,000. As a result, the implied multiple of enterprise value to revenue rounds to zero for both periods.

No company or transaction used in the analysis of Selected Precedent Transactions is identical to Endwave, GigOptix or the merger. An evaluation of this analysis is not entirely mathematical but rather involves complex considerations and judgments concerning differences in the financial, operating and other characteristics and factors that could affect the subject companies business or values. All multiples for the Selected Precedent Transactions were based on public information available at the time of the announcement of each transaction, without taking into account differing market and other conditions during the period in which the Selected Precedent Transactions occurred.

As an aspect in rendering its opinion, Merriman reviewed the premiums paid in 31 merger and acquisition transactions involving technology companies announced from March 2007 through November 2010 with enterprise values at the time of announcement of less than $100 million, which are referred to in this discussion as the Selected Transactions. Merriman selected these transactions by searching SEC filings, public company disclosures, press releases, industry and popular press reports, databases and other sources. Merriman compared the acquisition price to the price of the target’s common stock on the trading day prior to the date of the announcement of each transaction, on the trading day one week prior to the date of the announcement of each transaction and the trading day one month prior to the date of the announcement of each transaction. Merriman then examined the range of premiums for one day, one week, and one month. The results are set forth in the following table:

By way of comparison, the range of premiums for Endwave derived from the offer from GigOptix, as of February 3, 2011, was 0.0% premium for one day prior, 0.0% premium for one week prior and 2.2% discount for one month prior. Merriman noted that for all periods considered the implied premiums and discount for the merger were within the range of calculated values.

No company or transaction used in the analysis of Premiums Paid is identical to Endwave, GigOptix or the merger. An evaluation of this analysis is not entirely mathematical but rather involves complex considerations and judgments concerning differences in the financial, operating and other characteristics and factors that could affect the subject companies business or values. All premiums for the Selected Transactions were based on public information available at the time of announcement of each transaction, without taking into account differing market and other conditions during the period during which the Selected Transactions occurred.

Merriman reviewed the stock price performance of Endwave common stock relative to the Nasdaq Composite Index, the Russell 5000 Index, and an index comprised of the seven publicly traded companies used in the prior analysis. It was noted that Endwave’s stock price had fallen over 5% in the 60 days preceding the date of the analysis while all other all other indices had gained during this same period.

The following table sets forth the stock price performance of Endwave and each of the abovementioned indices:

Merriman did not conduct a discounted cash flow analysis due to the lack of predictability of future cash flows for Endwave.

The summary set forth above does not purport to be a complete description of the analyses performed by Merriman in connection with rendering its opinion. The preparation of a fairness opinion is a complex process involving the application of subjective business judgment in determining the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances and, therefore, is not readily susceptible to summary description. Merriman believes that its analyses must be considered as a whole and that considering any portion of its analyses and of the factors considered without considering all analyses and factors could create a misleading view of the process underlying its opinion. In arriving at its fairness determination, Merriman did not assign specific weights to any particular analyses.

In conducting its analyses and arriving at its opinion, Merriman utilized a variety of generally accepted valuation methods. The analyses were prepared solely for the purpose of enabling Merriman to provide its opinion to Endwave’s board of directors as to the fairness of the merger consideration, from a financial point of view, to the holders of the outstanding shares of Endwave common stock, and do not purport to be appraisals or necessarily reflect the prices at which businesses or securities actually may be sold, which are inherently subject to uncertainty. In connection with its analyses, Merriman made, and was provided by Endwave’s management with, numerous assumptions with respect to industry performance, general business and economic conditions and other matters, many of which are beyond Endwave’s control. Analyses based on estimates or forecasts of future results are not necessarily indicative of actual past or future values or results, which may be significantly more or less favorable than suggested by such analyses. Because such analyses are inherently subject to uncertainty,

being based upon numerous factors or events beyond the control of Endwave or its advisors, neither Endwave nor Merriman nor any other person assumes responsibility if future results or actual values are materially different from these forecasts or assumptions.

The terms of the merger were determined through negotiations between Endwave and GigOptix and were approved by Endwave’s board of directors. Although Merriman provided advice to Endwave during the course of these negotiations, the decision to enter into the merger was solely that of Endwave’s board of directors. As described above, the opinion and presentation of Merriman to Endwave’s board of directors were only one of a number of factors taken into consideration by Endwave’s board of directors in making its determination to approve the merger. Merriman’s opinion was provided to Endwave’s board of directors to assist it in connection with its consideration of the merger and does not constitute a recommendation to any holder of Endwave common stock as to how to vote with respect to the merger.

Under the terms of its engagement letter with Merriman, Endwave has paid to Merriman a nonrefundable fee of $175,000 for rendering Merriman’s fairness opinion and $70,000 as a retainer for its financial advisory services. In addition, contingent upon the closing of the Merger, Merriman will become entitled to receive a cash payment calculated by reference to the aggregate value of the GigOptix common stock to be issued in the Merger. Assuming 9,189,580 shares of GigOptix common stock are issued in the merger and using the value of such shares on April 27, 2011, such contingent fee would be approximately $578,000, less the $70,000 retainer previously paid by Endwave.

Endwave’s board of directors selected Merriman as its financial advisor because it is a recognized investment banking firm that has substantial experience in transactions similar to this transaction. As part of its investment banking business, Merriman is frequently engaged in the evaluation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, secondary distributions of securities, private placements and other purposes. Merriman has had no other investment banking relationship with Endwave. However, from October 27, 2004 to June 19, 2009, Merriman made a market in the common stock of Endwave. Merriman has had no investment banking relationship with GigOptix. Merriman may in the future provide investment banking and financial advisory services to Endwave or GigOptix unrelated to the proposed merger, for which Merriman would expect to receive compensation.

Endwave does not as a matter of course make public long-term forecasts as to future performance beyond the current fiscal year, and Endwave is especially wary of making forecasts for extended periods due to the unpredictability of the underlying assumptions and estimates. However, as part of the due diligence review of Endwave in connection with the merger, Endwave’s management provided to GigOptix, as well as to Merriman in connection with its evaluation of the fairness of the merger consideration, certain non-public, internal financial forecasts regarding Endwave’s anticipated future operations for the 2010 through 2012 fiscal years, in each case as prepared as of January 6, 2011. Endwave has included below a summary of these forecasts to give stockholders and investors access to certain non-public information that was furnished to third parties. These forecasts were considered by the Endwave board of directors for purposes of evaluating the merger.

These internal financial forecasts were not prepared with a view toward public disclosure, nor were they prepared with a view toward compliance with published guidelines of the SEC, the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of financial forecasts, or generally accepted accounting principles in the United States. In addition, these internal financial forecasts were prepared by, and are the responsibility of, Endwave’s management. Neither Endwave’s independent registered public accountants or any other independent registered public accountants have examined, compiled or performed any procedures with respect to these internal financial forecasts and, accordingly, do not express an opinion or any other form of assurance with respect thereto. The reports of independent public accountants included in this proxy statement/prospectus relate to the historical financial information of Endwave and GigOptix. They do not extend to the prospective financial information and should not be read to do so. The

summary of these internal financial forecasts included below is not being included to influence your decision whether to vote for the merger and the transactions contemplated in connection with the merger, but are being provided because these internal financial forecasts were provided by Endwave to GigOptix and Merriman.

These internal financial forecasts were based on numerous variables and assumptions (including, but not limited to, those related to industry performance and competition and general business, economic, market and financial conditions) that are inherently subjective and uncertain and are beyond the control of Endwave’s management. Important factors that may affect actual results and cause these internal financial forecasts to not be achieved include, but are not limited to, risks and uncertainties relating to Endwave’s business (including its ability to achieve strategic goals, objectives and targets over applicable periods), industry performance, general business and economic conditions and other factors described under “Special Cautionary Note Regarding Forward-Looking Statements” and the “Risk Factors” section of Endwave’s Annual Report on Form 10-K, as updated by subsequent Quarterly Reports on Form 10-Q, all of which are filed with the SEC. These internal financial forecasts also reflect assumptions as to certain business decisions that are subject to change. As a result, actual results may differ materially from those contained in these internal financial forecasts. Accordingly, there can be no assurance that the forecasted results summarized below will be realized.

The inclusion of a summary of these internal financial forecasts in this joint proxy statement/prospectus should not be regarded as an indication that any of Endwave, GigOptix or their respective affiliates, advisors or representatives considered these internal financial forecasts to be predictive of actual future events, and these internal financial forecasts should not be relied upon as such. In fact, GigOptix did not consider the internal financial forecasts in this joint proxy statement/prospectus as provided to it by Endwave to be predictive of actual future events concerning Endwave and did not rely on the projections as stated therein by Endwave. As such, GigOptix did not provide these forecasts to Roth or ask Roth to consider these forecasts in connection with Roth rendering its opinion to GigOptix. None of Endwave, GigOptix or their respective affiliates, advisors, officers, directors, partners or representatives can give you any assurance that actual results will not differ materially from these internal financial forecasts, and none of them undertakes any obligation to update or otherwise revise or reconcile these internal financial forecasts to reflect circumstances existing after the date these internal financial forecasts were generated or to reflect the occurrence of future events, even in the event that any or all of the assumptions underlying these forecasts are shown to be in error. Endwave does not intend to make publicly available any update or other revision to these internal financial forecasts. None of Endwave or its affiliates, advisors, officers, directors, partners or representatives has made or makes any representation to any stockholder or other person regarding Endwave’s ultimate performance compared to the information contained in these internal financial forecasts or that the forecasted results will be achieved.

Endwave has made no representation to GigOptix, in the merger agreement or otherwise, concerning these internal financial forecasts. The below forecasts do not give effect to the merger. Endwave urges all stockholders to review Endwave’s most recent SEC filings for a description of Endwave’s reported financial results.

The full text of the written opinion of Roth Capital Partners, which is referred to in this proxy statement/prospectus as Roth, dated as of February 4, 2011, is attached to this proxy statement/prospectus as Annex C. The opinion sets forth, among other things, the assumptions made, procedures followed, matters considered and

limitations on the scope of the review undertaken by Roth in rendering its opinion. You are encouraged to read the entire opinion carefully and in its entirety.

In arriving at its opinion, Roth assumed and relied upon, without independent verification, the accuracy and completeness of the information that was publicly available or supplied or otherwise made available to Roth by GigOptix and Endwave and formed a substantial basis for its opinion.

With respect to the financial projections, Roth assumed that they had been reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of GigOptix’ management as to the future financial performance of the company. In addition, Roth assumed that the merger will be consummated in accordance with the terms set forth in the merger agreement without any waiver, amendment or delay of any terms or conditions, and in compliance with applicable law. Roth assumed that in connection with the receipt of all the necessary governmental, regulatory or other approvals and consents required for the proposed merger, no delays, limitations, conditions or restrictions will be imposed or waivers made that would have a material adverse effect on the contemplated benefits expected to be derived in the proposed merger. Roth is not a legal, tax or regulatory advisor.

Roth was not an advisor on the transaction with Endwave and was engaged only in the capacity of rendering a fairness opinion to the GigOptix board of directors. Roth relied upon, with the consent of GigOptix

management, the foregoing information being supplied to Roth being accurate and complete in all material respects, and Roth further relied upon the assurances of management of GigOptix that they were not aware of any facts that would make any of the information reviewed by Roth to be inaccurate, incomplete or misleading in any material respect. Further, Roth did not independently verify any such information. With respect to the transaction forecast, Roth assumed, at the direction of GigOptix management, that it has been reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the management as to the future financial performance of Endwave. Roth did not make any independent valuation or appraisal of the GigOptix or Endwave assets or liabilities, nor was Roth furnished with any such appraisals. Roth’s opinion was necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to Roth as of, February 4, 2011.

Events occurring after February 4, 2011 may affect its opinion and the assumptions used in preparing it, and Roth did not assume any obligation to update, revise or reaffirm its opinion.

The following is a brief summary of each of the material analyses performed by Roth in connection with its oral opinion and the preparation of its written opinion letter dated February 4, 2011.

The various analyses summarized below were based on the closing price of $2.50 per share of GigOptix common stock as of February 3, 2011, the last full trading day prior to the meeting of GigOptix’ board of directors to consider and approve, adopt and authorize the merger agreement. Some of these summaries of financial analyses include information presented in tabular format. In order to fully understand the financial analyses used by Roth, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses.

Roth performed a comparable company analysis, which attempts to provide an implied value of a company by comparing it to similar companies that are publicly traded. Roth compared certain Endwave financial information with comparable publicly available consensus revenue estimates for companies that shared similar business characteristics with Endwave, which are referred to in this proxy statement/prospectus as the “comparable companies.” These companies comprised the following:

For purposes of this analysis, Roth analyzed the following statistics of each of these companies for comparison purposes:

Based on the analysis of the relevant metrics for each of the comparable companies, Roth selected representative ranges of financial multiples and applied these ranges of multiples to the relevant financial statistics of Endwave. For purposes of estimated fiscal years 2010 and 2011 revenue, Roth utilized estimates prepared by the GigOptix management team.

Based on its analysis, Roth estimated the implied value of Endwave equity as of February 3, 2011 to be as follows:

No company utilized in the comparable company analysis is identical to Endwave. In evaluating comparable companies and selecting representative ranges of financial multiples, Roth made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond GigOptix’ control, such as the impact of competition on GigOptix’ business and the industry generally, industry growth and the absence of any adverse material change in GigOptix’ financial condition and prospects or in the industry or financial markets in general. Mathematical analysis (such as determining the average or median) is not in itself a meaningful method of using peer group data.

Roth performed a discounted cash flow analysis, which is designed to provide insight into the estimated value of a company’s equity as a function of the company’s estimated future free cash flows. The resulting value is subsequently discounted to arrive at an enterprise value for such company. Based on the closing price of GigOptix common stock as of February 3, 2011 of $2.50 per share which Roth used in conducting its analyses, Roth attributed a total value to the consideration being paid by GigOptix of approximately $22.8 million. The equity value of a company is determined by subtracting both total debt and cash and cash equivalents from the enterprise value of a company. As a result, the equity value component of the $22.8 million price being paid by GigOptix would subtract the amount of cash and cash equivalents which Endwave would hold upon consummation of the merger from the $22.8 million.

To calculate Endwave’s equity value, Roth used fiscal year 2011 to 2014 financial forecasts for Endwave prepared by GigOptix management. Roth then applied discount rates ranging from 20% to 24% based on the

estimated cost of capital for Endwave and a terminal growth rate of Endwave free cash flow of 1% to 5%. Based on the discounted cash flow analysis, Roth estimated a current equity value ranging from $9.9 million to $17.4 million, and a enterprise value in excess of that amount by the amount of the cash and cash equivalents which Endwave would hold upon consummation of the merger. Such enterprise value was higher than the $22.8 million value of the consideration being paid by GigOptix.

Roth performed a precedent transactions analysis, which is designed to imply a value of a company based on applying publicly available financial terms of selected prior transactions that share some characteristics with this transaction. In connection with its analysis of precedent transactions, Roth compared publicly available statistics for selected technology sector transactions occurring between January 1, 2008 and February 3, 2011 in the semiconductor and electronics areas.

In connection with its analysis of precedent transaction multiples, Roth compared publicly available statistics for 29 selected transactions involving companies that shared certain similar business characteristics with Endwave occurring between January 1, 2008 and February 3, 2011. The following is a list of these transactions:

For each transaction referenced above, Roth noted the following financial statistic where available

Based on an analysis of the relevant metrics and time frame for each transaction referenced above, Roth selected ranges of financial multiples of the transactions and applied these ranges of financial multiples to the relevant financial statistic of Endwave.

No company or transaction utilized in the precedent transactions analysis is identical to Endwave or the transaction at hand. In evaluating the precedent transactions and selecting ranges of implied premiums and financial multiples, Roth made judgments and assumptions with regard to general business, market and financial conditions and other matters, which are beyond its control, such as the impact of competition on Endwave’s business or its industry generally, industry growth and the absence of any material adverse change in its financial condition or in its industry or financial markets in general, which could affect the public trading value of the companies and the aggregate value and equity value of the transactions to which they are being compared.

In connection with the review of the merger by the GigOptix’ board of directors, Roth performed a variety of financial and comparative analyses for purposes of rendering its opinion. The preparation of a financial opinion is a complex process and is not necessarily susceptible to a partial analysis or summary description. In arriving at its opinion, Roth considered the results of all of its analyses as a whole and did not attribute any particular weight to any analysis or factor it considered. Roth believes that selecting any portion of its analyses, without considering all analyses as a whole, would create an incomplete view of the process underlying its analyses and opinion. In addition, Roth may have given various analyses and factors more or less weight than other analyses and factors, and may have deemed various assumptions more or less probable than other assumptions. As a result, the ranges of valuations resulting from any particular analysis described above should not be taken to be Roth’s view of the actual value of Endwave. In performing its analyses, Roth made numerous assumptions with respect to industry performance, general business and economic conditions and other matters. Many of these assumptions are beyond its control. Any estimates contained in Roth’s analyses are not necessarily indicative of future results or actual values, which may be significantly more or less favorable than those suggested by such estimates.

Roth conducted the analyses described above solely as part of its analysis of the fairness of the merger consideration paid pursuant to the merger agreement from a financial point of view to holders of shares of GigOptix common stock and in connection with the delivery of its opinion, dated February 4, 2011, to the GigOptix board of directors. These analyses do not purport to be appraisals or to reflect the prices at which shares of Endwave or GigOptix common stock might actually trade.

The consideration was determined through arm’s length negotiations between GigOptix and Endwave and was approved by the GigOptix and Endwave boards of directors. Roth did not provide advice to GigOptix’ board of directors during these negotiations.

Roth’s opinion and its presentation to GigOptix’ board of directors was one of many factors taken into consideration by the GigOptix board of directors in deciding to approve, adopt and authorize the merger agreement. Consequently, the analyses as described above should not be viewed as determinative of the opinion of GigOptix’ board of directors with respect to the merger consideration or of whether GigOptix’ board of directors would have been willing to agree to different consideration.

The GigOptix board of directors retained Roth based upon Roth’s qualifications, experience and expertise. Roth is a recognized investment banking and advisory firm. Roth, as part of its investment banking and financial advisory business, is continuously engaged in the valuation of businesses and securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for corporate, estate and other purposes. In the ordinary course of Roth’s trading, brokerage, and financing activities, Roth, its affiliates, directors and officers may at any time invest on a principal basis, hold long or short positions, finance positions and may trade or otherwise effect transactions, for their own account or for the accounts of customers in the debt or equity securities or senior loans of GigOptix, Endwave or any other parties, commodities or currencies that may be involved in the transactions contemplated by the merger agreement or any related derivative instrument. In the two years prior to the date of its opinion, Roth has provided financial advisory or financing services for GigOptix and has received fees in connection with such services.

GigOptix’ engagement letter with Roth provides that Roth will receive fees for its services that are not contingent upon the closing of any business combination. As compensation for Roth’s services and its delivery of a fairness opinion in connection with the transaction, GigOptix has agreed to pay Roth a fee of $150,000.

In addition, GigOptix has agreed to indemnify Roth and its affiliates, their respective directors, officers, agents and employees and each person, if any, controlling Roth or any of its affiliates against certain liabilities and expenses, including certain liabilities under the federal securities laws, relating to or arising out of Roth’s engagement or any related transactions. Roth’s opinion was not approved by any committee at Roth.

GigOptix does not as a matter of course make public long-term forecasts as to future performance beyond the current fiscal year, and GigOptix is especially wary of making forecasts for extended periods due to the unpredictability of the underlying assumptions and estimates. However, as part of the due diligence review of GigOptix in connection with the merger, GigOptix’ management provided to Endwave certain non-public, internal financial forecasts regarding GigOptix’ anticipated future operations for the 2010 through 2012 fiscal years, in each case as prepared as of December 17, 2010. Endwave provided such internal financial forecasts to Merriman in connection with its evaluation of the fairness of the merger consideration. GigOptix has included below a summary of these forecasts to give stockholders and investors access to certain non-public information that was furnished to third parties. These forecasts were considered by the GigOptix board of directors for purposes of evaluating the merger.

These internal financial forecasts were not prepared with a view toward public disclosure, nor were they prepared with a view toward compliance with published guidelines of the SEC, the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of financial forecasts, or generally accepted accounting principles in the United States. In addition, these internal financial forecasts were prepared by, and are the responsibility of, GigOptix’ management. Neither GigOptix’ independent registered public accountants or any other independent registered public accountants have examined, compiled or performed any procedures with respect to these internal financial forecasts and, accordingly, do not express an opinion or any other form of assurance with respect thereto. The reports of independent public accountants included in this proxy statement/prospectus relate to the historical financial information of GigOptix and Endwave. They do not extend to the prospective financial information and should not be read to do so. The summary of these internal financial forecasts included below is not being included to influence your decision whether to vote for the merger and the transactions contemplated in connection with the merger, but because these internal financial forecasts were provided to Endwave and Merriman.

management. Important factors that may affect actual results and cause these internal financial forecasts to not be achieved include, but are not limited to, risks and uncertainties relating to GigOptix’ business (including its ability to achieve strategic goals, objectives and targets over applicable periods), industry performance, general business and economic conditions and other factors described in “Special Cautionary Note Regarding Forward-Looking Statements” and the “Risk Factors” section of GigOptix’ Annual Report on Form 10-K, as updated by subsequent Quarterly Reports on Form 10-Q, all of which are filed with the SEC. These internal financial forecasts also reflect assumptions as to certain business decisions that are subject to change. As a result, actual results may differ materially from those contained in these internal financial forecasts. Accordingly, there can be no assurance that the forecasted results summarized below will be realized.

The inclusion of a summary of these internal financial forecasts in this joint proxy statement/prospectus should not be regarded as an indication that any of GigOptix, Endwave or their respective affiliates, advisors or representatives considered these internal financial forecasts to be predictive of actual future events, and these internal financial forecasts should not be relied upon as such. None of GigOptix, Endwave or their respective affiliates, advisors, officers, directors, partners or representatives can give you any assurance that actual results will not differ materially from these internal financial forecasts, and none of them undertakes any obligation to update or otherwise revise or reconcile these internal financial forecasts to reflect circumstances existing after the date these internal financial forecasts were generated or to reflect the occurrence of future events, even in the event that any or all of the assumptions underlying these forecasts are shown to be in error. GigOptix does not intend to make publicly available any update or other revision to these internal financial forecasts. None of GigOptix or its affiliates, advisors, officers, directors, partners or representatives has made or makes any representation to any stockholder or other person regarding GigOptix’ ultimate performance compared to the information contained in these internal financial forecasts or that the forecasted results will be achieved. GigOptix has made no representation to Endwave, in the merger agreement or otherwise, concerning these internal financial forecasts. The below forecasts do not give effect to the merger. GigOptix urges all stockholders to review GigOptix’ most recent SEC filings for a description of GigOptix’ reported financial results.

The merger agreement provides that GigOptix will, or cause Endwave as the surviving corporation in the merger to, after the effective time of the merger, fulfill and honor the obligation of Endwave to indemnify Endwave’s present and former directors and officers pursuant to the terms of Endwave’s amended and restated certificate of incorporation and bylaws as in effect on the date of the merger agreement.

The merger agreement also provides that neither GigOptix nor Endwave as the surviving corporation in the merger will take any action to terminate any liability insurance that Endwave acquires and fully pays for prior to the effective time of the merger with respect to claims arising against Endwave’s officers and directors with respect to their acts and omissions as directors and officers of Endwave occurring prior to the effective time of the merger. However, Endwave as the surviving corporation in the merger may substitute a policy of at least the same coverage containing terms and conditions that, in the aggregate, are no less advantageous.

It is expected that Dr. Avi Katz will maintain his position as Chairman of the Board of Directors, Chief Executive Officer and President of the combined company. Curt P. Sacks, the current Chief Financial Officer of Endwave, is expected to serve as the Chief Financial Officer of the combined company. Andrea Betti-Berutto, the current Chief Technology Officer of GigOptix, is expected to serve as the Chief Technology Officer of the combined company. Other key executives from both companies will be combined to serve on the management team. GigOptix’ new board of directors is expected to consist of all five existing GigOptix directors and two Endwave directors, John Mikulsky and Joseph Lazzara. Information about the current GigOptix directors and executive officers, as well as board nominees Mr. Mikulsky and Mr. Lazzara, can be found at “Information About GigOptix, Inc.—Directors and Executive Officers” and “Information About GigOptix, Inc.—Anticipated Executive Officers of GigOptix Following the Merger” beginning on pages 67 and 69 of this proxy statement/prospectus, respectively.

Endwave’s executive officers and directors have financial interests in the merger that are different from, or in addition to, their interests as Endwave stockholders generally. The Endwave board of directors was aware of and considered these interests, among other matters, in evaluating the merger agreement and in recommending that the Endwave stockholders adopt the merger agreement.

The compensation committee of Endwave’s board of directors believes that it is in the best interests of stockholders if Endwave’s executive officers are able to focus on Endwave’s business during both strong and weak business cycles without being distracted by the near-term financial impact that a potential termination of employment might have on them personally. The compensation committee of Endwave’s board of directors also believes it is in the best interests of stockholders if Endwave’s executive officers are able to evaluate the potential merits of a change of control transaction objectively without being distracted by the potentially adverse personal impact on themselves. The compensation committee of Endwave’s board of directors believes that the total potential value of all change of control agreements with Endwave’s executive officers is not disproportionate to the overall market value of Endwave.

Under Endwave’s Senior Executive Officer Severance and Retention Plan, if Mr. Mikulsky’s employment is terminated by Endwave or its successor without cause, or Mr. Mikulsky terminates his employment for certain specified reasons in connection with, or within six months after, the merger, he will receive salary continuation for 42 months and acceleration of vesting of all of his stock options and restricted stock units. Under Endwave’s Executive Officer Severance Plan, if the employment of any of Mr. Sacks, Dan Teuthorn, Endwave’s Senior Vice President of Engineering, or Steve Layton, Endwave’s Senior Vice President of Sales, is terminated by Endwave or its successor without cause, or by the executive officer for certain specified reasons in connection with, or within six months after, the merger, the executive officer will receive salary continuation for 12 months and the accelerated vesting for all of the executive officer’s outstanding stock options and restricted stock units.

Endwave’s directors and executive officers each hold restricted stock units and options to acquire shares of Endwave common stock. Under the terms of the merger agreement and Endwave’s equity incentive plan, the vesting of all options and restricted stock units to acquire Endwave common stock, not just options and restricted stock units held by directors and executive officers, will accelerate in connection with the transaction regardless of whether the holder’s employment or other service relationship with Endwave terminates. The completion of the merger will result in, among other things, the conversion of restricted stock units and in-the-money options to acquire Endwave common stock into shares of GigOptix common stock as described in this proxy statement/prospectus.

connection with the merger, assuming the closing of the merger and termination of employment occurred on December 31, 2010:

Certain of Endwave’s executive officers will be employed by GigOptix after the merger. Agreements with these executive officers are being negotiated but have not yet been entered into.

If the merger is completed, Endwave common stock will be delisted from the Nasdaq Global Market and deregistered under the Exchange Act.

Restrictions on Sales of Shares of GigOptix Common Stock Received in the Merger

The shares of GigOptix common stock to be issued in connection with the merger will be freely transferable under the Securities Act, except for shares issued to any stockholder who may be deemed to be an “affiliate” of GigOptix for purposes of Rule 144 under the Securities Act. Persons who may be deemed to be affiliates include individuals or entities that control, are controlled by, or are under common control with, GigOptix and may include the executive officers, directors and significant stockholders of GigOptix.

Following the merger, the pre-merger holders of Endwave common stock and restricted stock units will own that number of shares equal to approximately 42.5% of the outstanding stock of the combined company, less 42.5% of the shares issued in respect of Endwave stock options. If the transaction were closed on March 2, 2011, approximately 9,035,557 shares of GigOptix common stock would be issued in connection with the merger to the holders of Endwave common stock and restricted stock units, and approximately 121,736 shares of GigOptix common stock would be issued in connection with the merger to the holders of Endwave stock options. The merger will be accounted for using the purchase method of accounting. GigOptix will be the acquiring entity for purposes of applying the purchase method of accounting. As GigOptix will be the accounting acquirer, the historical statements of GigOptix will become the historical financial statements of the combined entity. The net assets, including identified intangible assets and liabilities of Endwave at the effective time of the merger, will be recorded at their respective fair values. The fair value of the consideration at the time of the merger will be the fair value of the shares issued to Endwave based on the closing market price per share of GigOptix shares on the

date of the merger. The purchase price will be allocated to the identified tangible and intangible assets acquired and liabilities assumed in the merger; to the extent that the purchase price exceeds the net assets acquired, goodwill will be recorded. GigOptix management will determine the fair value of the identified tangible and intangible assets acquired and liabilities assumed using established valuation techniques.

Endwave stockholders will be entitled to appraisal rights under the DGCL and receive payment for the fair value of their Endwave shares if the merger is completed and the dissenting stockholders follow the requirements of Section 262 of the DGCL.

A holder of record of shares of Endwave common stock outstanding immediately prior to the effective time of the merger who has not voted in favor of, or consented in writing to, the approval and adoption of the merger agreement, and who has delivered a written demand for appraisal of such shares executed by or on behalf of the stockholder of record in accordance with Section 262 of the DGCL, will not have his, her or its shares converted into the right to receive the merger consideration unless and until the dissenting stockholder fails to perfect or effectively withdraws or otherwise loses his, her or its right to appraisal and payment under the DGCL. If, after the effective time of the merger, a dissenting stockholder fails to perfect or otherwise waives, or withdraws or loses his, her or its right to appraisal, or a court determines that such holder is not entitled to relief under the DGCL, then such holder or holders (as the case may be) will forfeit such rights and his, her or its shares of Endwave common stock will be treated as if they had been converted as of the effective time of the merger into the right to receive the merger consideration (in the form of shares of GigOptix common stock) without interest thereon, upon surrender of the certificate or certificates that formerly evidenced such shares.

The following discussion is not a complete statement of appraisal rights under the DGCL and is qualified in its entirety by the full text of Section 262 of the DGCL, which explains the procedures and requirements for exercising statutory appraisal rights and which is attached as Annex D to this joint proxy statement/prospectus and incorporated herein by reference. All references in Section 262 of the DGCL and in this summary to a “stockholder” are, unless otherwise indicated, to the record holder of the shares of Endwave’s common stock as to which appraisal rights are asserted. Stockholders intending to exercise appraisal rights should review Annex D carefully. This joint proxy statement/prospectus constitutes notice to Endwave’s stockholders concerning the availability of appraisal rights under Section 262 of the DGCL.

An Endwave stockholder who wishes to exercise appraisal rights should review carefully the following discussion and Annex D to this joint proxy statement/prospectus, because failure to comply timely and fully with the procedures required by Section 262 of the DGCL will result in the loss of any available appraisal rights.

Endwave stockholders who do not wish to accept shares of GigOptix common stock as the merger consideration will be entitled to, subject to compliance with the requirements summarized below, demand an appraisal by the Delaware Court of Chancery of the “fair value” of their shares of Endwave common stock and be paid in cash such amount in lieu of the merger consideration that they would otherwise be entitled to receive if the merger is consummated. For this purpose, the fair value of shares of Endwave common stock will be their fair value, excluding any element of value arising from the consummation or expectation of consummation of the merger, but including, unless the court in its discretion determines otherwise for good cause shown, interest from the effective date of the merger through the date of payment of the judgment compounded quarterly and accruing at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the merger and the date of payment of the judgment. Stockholders who desire to exercise their appraisal rights must satisfy all of the conditions of Section 262 of the DGCL, including:

Neither voting (in person or by proxy) against, abstaining from voting on or failing to vote on the proposal to approve and adopt the merger agreement will constitute a written demand for appraisal within the meaning of Section 262 of the DGCL. The written demand for appraisal must be in addition to and separate from any proxy or vote.

A demand for appraisal must be executed by or on behalf of the stockholder of record, fully and correctly, as such stockholder’s name appears on the stock certificate and must state that such person intends to demand appraisal of his, her or its shares of Endwave common stock. If the shares are owned of record by a person other than the beneficial owner, including a bank broker, custodian or other nominee, depositary or other nominee, this demand must be executed by or for the record owner. If the shares are owned by or for more than one person, as in a joint tenancy or tenancy in common, the demand must be executed by or for all joint owners. An authorized agent, including an agent for two or more joint owners, may execute the demand for appraisal for a stockholder of record. However, the agent must identify the record owner and expressly disclose that, in exercising the demand, he is acting as agent for the record owner. A person having a beneficial interest in Endwave common stock held of record in the name of another person, such as a broker or nominee, must act promptly to cause the record holder to follow the steps summarized herein in a timely manner to perfect whatever appraisal rights the beneficial owner may have.

A stockholder who elects to exercise appraisal rights should mail or deliver his, her or its written demand to Endwave’s principal executive offices at 130 Baytech Drive, San Jose, CA 95134, Attention: Corporate Secretary. The written demand for appraisal should state the stockholder’s name and mailing address, the number of shares of Endwave common stock owned by the stockholder and must reasonably inform Endwave that the stockholder intends thereby to demand appraisal of his, her or its shares of Endwave common stock. Within ten days after the effective date of the merger, Endwave will provide notice of the effective date of the merger to all Endwave stockholders who have complied with Section 262 of the DGCL and have not voted for the merger. A record holder, such as a broker, custodian or other nominee, depositary or other nominee, who holds shares of Endwave common stock as a nominee for others, may exercise appraisal rights with respect to the shares held for all or less than all beneficial owners of shares as to which that person is the record owner. In that case, the written demand must set forth the number of shares covered by the demand. When the number of shares is not expressly stated, the demand will be presumed to cover all shares of Endwave common stock outstanding in the name of that record owner.

Within 120 days after the effective date of the merger (but not thereafter), any stockholder (including any beneficial owner of shares entitled to appraisal rights) who is entitled to appraisal rights in connection with the merger and has satisfied the requirements of Section 262 of the DGCL may deliver to Endwave a written demand for a statement listing the aggregate number of shares not voted in favor of the merger and with respect to which demands for appraisal have been received and the aggregate number of holders of those shares. Endwave, as the surviving corporation in the merger, must mail that written statement to the stockholder within ten days after the stockholder’s request is received by Endwave or within ten days after the latest date for delivery of a demand for appraisal under Section 262 of the DGCL, whichever is later. If a petition for appraisal rights is timely filed in the Court of Chancery of the State of Delaware as set forth above and a copy is served on Endwave, Endwave must then, within 20 days after service, file in the office of the Delaware Register in Chancery, a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached with Endwave. If Endwave files a petition, the petition must be accompanied by the duly verified list. The Register in Chancery, if so ordered by the court, will give notice of the time and place fixed for the hearing of that petition by registered or certified mail to Endwave and to the stockholders shown on the list at the addresses therein stated, and notice also will be given by publishing a notice at least one week before the day of the hearing in a newspaper of general circulation published in the City of Wilmington, Delaware, or such publication as the court deems advisable. The court must approve the forms of the notices by mail and by publication, and Endwave must bear the costs of the notices.

At the hearing on the petition, the Court of Chancery of the State of Delaware will determine which stockholders have become entitled to appraisal rights. The court may require the stockholders who have demanded an appraisal for their shares (and who hold stock represented by certificates) to submit their stock certificates to the Register in Chancery for notation of the pendency of the appraisal proceedings and the Court of Chancery of the State of Delaware may dismiss the proceedings as to any stockholder that fails to comply with that direction.

After determining which stockholders are entitled to appraisal rights, the court will appraise the shares owned by those stockholders, determining the “fair value” of those shares, exclusive of any element of value arising from the accomplishment or expectation of the merger, together with interest to be paid, if any, upon the amount determined to be the fair value. In determining the fair value, the court must take into account all relevant factors. Endwave stockholders considering seeking appraisal of their shares should note that the fair value of their shares determined under Section 262 of the DGCL could be more than, the same as or less than the value they would receive pursuant to the merger agreement if they did not seek appraisal of their shares.

The costs of the appraisal proceeding may be determined by the court and taxed against the parties as the court deems equitable under the circumstances. However, costs do not include attorney’s and expert witness fees. Each dissenting stockholder is responsible for his, her or its attorney’s and expert witness fees, although, upon application of a stockholder who has perfected appraisal rights, the court may order that all or a portion of the

expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney’s fees and the fees and expenses of experts, be charged pro rata against the value of all shares entitled to appraisal.

If a stockholder demands appraisal rights in compliance with the requirements of Section 262 of the DGCL, then, after the effective time of the merger, that stockholder will not be entitled to: (i) vote that stockholder’s shares of Endwave common stock for any purpose; (ii) receive payment of dividends or other distributions on that stockholder’s shares that are payable to stockholders of record at a date after the effective time of the merger; or (iii) receive payment of any consideration provided for in the merger agreement. A stockholder may withdraw his, her or its demand for appraisal rights by a writing withdrawing his, her or its demand for appraisal and accepting the merger consideration at any time within 60 days after the effective time of the merger, or at any time thereafter with Endwave’s written approval. Notwithstanding the foregoing, no appraisal proceeding in the Delaware Court of Chancery may be dismissed as to any stockholder without the approval of the court and that approval may be conditioned upon such terms as the court deems just, but this rule does not affect the right of any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party to withdraw that stockholder’s demand for appraisal and to accept the terms offered in the merger agreement within 60 days after the effective date of the merger. Subject to the foregoing, if any Endwave stockholder withdraws his, her or its demand for appraisal rights, then his, her or its shares of Endwave common stock will be automatically converted into the right to receive shares of GigOptix common stock, as the merger consideration, without interest.

Any stockholder wishing to exercise appraisal rights is urged to consult legal counsel before attempting to do so. Failure to comply strictly with all of the procedures set forth in Section 262 of the DGCL may result in the loss of any available appraisal rights.

The merger agreement requires GigOptix to use commercially reasonable efforts to cause its common stock to be issued in the merger to be authorized for listing on the NYSE AMEX, subject to official notice of issuance, prior to the closing of the merger, and if that is not reasonably possible, then as soon thereafter as is reasonably possible. If within 60 days following the effective time of the merger, such shares of GigOptix common stock have not been so authorized, then the board of directors of GigOptix will use its best efforts to take further actions as appropriate to achieve such listing on NYSE AMEX, subject to official notice of issuance. GigOptix has submitted an application to list its common stock on the NYSE AMEX.

In order to complete the merger, GigOptix stockholders will not need to approve and adopt the merger agreement or the transactions contemplated thereby.

The following is a summary of the material terms of the merger agreement. This summary does not purport to describe all the terms of the merger agreement and is qualified in its entirety by reference to the complete merger agreement, which is attached as Annex A to this proxy statement/prospectus and incorporated by reference herein.

The summary below is included in this proxy statement/prospectus only to provide you with information regarding the terms and conditions of the merger agreement, and not to provide any other factual information regarding GigOptix, Endwave or their respective businesses. Accordingly, the representations and warranties and other provisions of the merger agreement should not be read alone, but instead should be read only in conjunction with the information provided elsewhere in this proxy statement/prospectus.

The representations, warranties and covenants contained in the merger agreement and described in this proxy statement/prospectus (i) were made only for purposes of the merger agreement and as of specific dates and may be subject to more recent developments; (ii) were made solely for the benefit of the parties to the merger agreement and may be subject to limitations agreed upon by the contracting parties, including being qualified by reference to disclosures, for the purposes of allocating risk between parties to the merger agreement instead of establishing these matters as facts; and (iii) may apply standards of materiality in a way that is different from what may be viewed as material by you or by other investors. Accordingly, these representations and warranties alone may not describe the actual state of affairs as of the date they were made or at any other time. The representations and warranties contained in the merger agreement do not survive the effective time of the merger. Investors should not rely on the representations, warranties and covenants or any description thereof as characterizations of the actual state of facts or condition of GigOptix or Endwave or any of their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations, warranties and covenants may change after the date of the merger agreement, which subsequent information may or may not be fully reflected in public disclosures by GigOptix and Endwave.

At the effective time of the merger, Merger Sub will be merged with and into Endwave. As a result of the merger, the separate corporate existence of Merger Subsidiary will cease and Endwave will survive as a wholly-owned subsidiary of GigOptix. Upon effectiveness of the merger, each Endwave stockholder will have the right to receive the merger consideration described below under “—Merger Consideration.”

The closing of the merger will take place at 8:00 a.m., Pacific time, on a date to be agreed by the parties, but not before May 1, 2011, which if not so agreed will be the third business day after satisfaction or waiver of the conditions to closing set forth in the merger agreement, other than those conditions that by their terms are to be satisfied at the closing. The closing will be held at the offices of GigOptix’ counsel in Palo Alto, California, unless the parties agree to another place.

If the merger is completed, GigOptix will issue shares of its common stock to holders of Endwave common stock, restricted stock units and in-the-money options. At the effective time of the merger, each share of Endwave common stock issued and outstanding immediately prior to the effective time of the merger (other than shares subject to perfected appraisal rights and other than shares held by Endwave, Merger Sub, GigOptix or any subsidiary of GigOptix, including shares issued upon settlement of all outstanding restricted stock units to acquire Endwave common stock, will be automatically converted into the right to receive the number of shares of GigOptix common stock based on a conversion ratio, which will be calculated as follows:

At the effective time of the merger, each outstanding option to purchase Endwave common stock shall terminate and cease to represent a right to acquire Endwave common stock, and each holder of an Endwave stock option will be entitled to receive a number of shares of GigOptix common stock equal to (a) the product of (i) the difference between the closing price of Endwave’s common stock as reported on the Nasdaq Global Market on the trading day immediately prior to the effective time of the merger and the per-share exercise price of the applicable Endwave stock option and (ii) the number of whole shares of Endwave common stock (with any fractional shares being settled in cash) that were issuable upon exercise of the applicable Endwave stock option, whether or not vested, divided by (b) the closing price per share of GigOptix common stock as reported on the OTC Bulletin Board on the trading day immediately preceding the effective time of the merger. Holders of Endwave stock options with an exercise price equal to or greater than the closing price of Endwave’s common stock as reported on the Nasdaq Global Market on the trading day immediately prior to the effective time of the merger, will not be entitled to receive any shares of GigOptix common stock for those stock options. We believe that treating options in this manner compensates the optionholders for the current realizable value of their options but prevents any future dilution to the holders of Endwave and GigOptix stock that would result if such options were assumed by GigOptix.

At the effective time of the merger, each restricted stock unit of Endwave common stock that is outstanding as of immediately prior to the effective time of the merger will terminate and cease to represent a right to acquire Endwave common stock, and each holder of an Endwave restricted stock unit will be entitled to receive a number of shares of GigOptix common stock equal to (a) the product of (i) the number of shares of Endwave common stock issuable upon settlement of the applicable Endwave restricted stock unit, whether or not vested, and (ii) the conversion ratio described above under “—Merger Consideration.”

In certain circumstances, holders of Endwave common stock who have not voted in favor of or consented to the merger, and have otherwise complied with the provisions of Section 262 of the DGCL as to appraisal rights, will be entitled to such rights as are granted by Section 262 of the DGCL. Any shares of Endwave common stock held by an Endwave stockholder who has demanded and perfected appraisal rights for such shares in accordance with the DGCL and who, as of the effective time of the merger, has not effectively withdrawn or lost such appraisal rights, will not be converted into or represent a right to receive the merger consideration, but instead shall be converted into the right to receive only the consideration as may be determined to be due with respect to such dissenting shares under the laws of the State of Delaware. From and after the effective time of the merger, a holder of dissenting shares will not be entitled to exercise any of the voting rights or other rights of a stockholder of Endwave as the surviving corporation in the merger.

If any Endwave stockholder who demands appraisal of such shares under DGCL effectively withdraws or loses (through failure to perfect or otherwise) the right to appraisal, then, as of the later of the effective time of the merger and the occurrence of such event, that Endwave stockholder’s shares will no longer be dissenting shares and will automatically be converted into and represent only the right to receive the merger consideration in the merger, without interest thereon, upon surrender of the certificate representing such shares. The merger agreement restricts Endwave from, except with the prior written consent of GigOptix, voluntarily making any payment with respect to any demands for appraisal of Endwave common stock or offer to settle or settle any such demands.

At or prior to the effective time of the merger, GigOptix shall supply to American Stock Transfer & Trust Company, LLC, as the exchange agent for the merger, in trust for the benefit of the holders of Endwave common stock, certificates (or, at the holder’s request, direct registration) evidencing the shares of GigOptix common stock to be exchanged for outstanding shares of Endwave common stock in the merger, and cash to be distributed to Endwave stockholders in lieu of fractional shares in the merger.

Promptly (and in no event more than five business days) after the effective time of the merger, GigOptix shall mail to each holder of Endwave common stock a letter of transmittal in customary form (which shall specify that delivery shall be effected, and risk of loss and title to the Endwave common stock certificates shall pass, only upon proper delivery of the Endwave common stock certificates to the exchange agent) and instructions for surrender of the Endwave common stock certificates. Upon surrender to the exchange agent of an Endwave common stock certificate (if any), together with such letter of transmittal duly executed, the holder of Endwave common stock will be entitled to receive in exchange for the holders Endwave common stock certificate (no later than five business days after the exchange agent’s receipt of the duly executed letter of transmittal and, if applicable, Endwave common stock certificate): (i) certificates evidencing that number of shares of GigOptix common stock issuable to the holder of Endwave common stock in connection with the merger; (ii) any dividends or other distributions that the holder of Endwave common stock has the right to receive pursuant to merger agreement; and (iii) cash in respect of fractional shares as provided in merger agreement, and such Endwave common stock certificate so surrendered will be cancelled. No certificate representing shares of GigOptix common stock will be issued to a person who is not the registered owner of a surrendered Endwave common stock certificate unless (i) the Endwave common stock certificate so surrendered has been properly endorsed or otherwise is in proper form for transfer, and (ii) such person shall either pay any transfer or other tax required by reason of the issuance or establish to the reasonable satisfaction of the Endwave as the surviving corporation in the merger that the tax has been paid or is not applicable. Until surrendered in accordance with the provisions of the merger agreement, from and after the effective time of the merger, each Endwave common stock certificate (except an Endwave common stock certificate representing dissenting shares) shall be deemed to represent, for all purposes other than payment of dividends, the right to receive a certificate representing the number of full shares of GigOptix common stock as determined in accordance the merger agreement and cash in lieu of fractional shares.

No dividend or other distribution will be paid or declared with respect to GigOptix common stock prior to the effective time of the merger. No dividend or other distribution declared with respect to GigOptix common stock with a record date after the effective time of the merger will be paid to holders of unsurrendered Endwave common stock certificates until the holders surrender their Endwave common stock certificates. Upon the surrender of the Endwave common stock certificates, there will be paid to such Holders, promptly after surrender of their Endwave common stock certificates, the amount of dividends or other distributions, excluding interest, declared with a record date after the effective time of the merger and not paid because of the failure to surrender Endwave common stock certificates for exchange.

In the event that any Endwave common stock certificates are lost, stolen or destroyed, the exchange agent will issue and pay in respect of the lost, stolen or destroyed Endwave common stock certificates, upon the making of an affidavit of that fact by the holder thereof, certificates representing the shares of GigOptix common

stock as may be required pursuant to merger agreement and cash in lieu of fractional shares, if any and any dividends or distributions as described in the previous paragraph; provided, however, that GigOptix may, in its discretion and as a condition precedent to the issuance thereof, require the owner of lost, stolen or destroyed Endwave common stock certificates to deliver a bond in such sum as it may reasonably direct as indemnity against any claim that may be made against GigOptix or the exchange agent with respect to the Endwave common stock certificates alleged to have been lost, stolen or destroyed.

No fraction of a share of GigOptix common stock will be issued by virtue of the merger. Instead, each holder of Endwave common stock who would otherwise be entitled to a fraction of a share of GigOptix common stock (after aggregating all fractional shares of GigOptix common stock to be received by such holder) will receive from GigOptix an amount of cash (rounded down to the nearest whole cent) based on the closing price per share of GigOptix common stock as reported on the OTC Bulletin Board on the trading day immediately preceding the effective time of the merger.

The merger agreement contains a number of representations and warranties made by both GigOptix and Endwave that are subject in some cases to exceptions and qualifications including exceptions that do not result in, and would not, individually or in the aggregate, reasonably be expected to have a “material adverse effect”. See also “—Definition of ‘Material Adverse Effect’” below. The representations and warranties in the merger agreement relate to, among other things:

Endwave also makes representations and warranties relating to, among other things, approval and recommendation to Endwave stockholders of the merger agreement and the merger by its board of directors and the accuracy of the information supplied by Endwave for inclusion in the registration statement of which this proxy statement/prospectus is a part.

GigOptix also makes representations and warranties relating to, among other things, the activities of Merger Sub and the accuracy and timeliness of its filings with the SEC.

The representations and warranties in the merger agreement do not survive after the completion of the merger.

Many of the representations and warranties in the merger agreement are qualified by “material adverse effect.” In addition, there are separate standalone conditions to completion of the merger relating to the absence of any event or occurrence or circumstance that, alone or together with any one or more other events, occurrences or circumstances, has had, is having or would reasonably be expected to result in a material adverse effect on the other party.

For purposes of the merger agreement, “material adverse effect” means, with respect to Endwave or GigOptix, as the case may be, any change, event, circumstance, condition or effect that is or is reasonably likely to be, individually or in the aggregate, materially adverse in relation to the condition (financial or otherwise), capitalization, properties, products, assets (including intangible assets), intellectual property, liabilities, business, operations, or results of operations of such entity and its subsidiaries, taken as a whole, except to the extent that any such change, event, condition or effect directly results from:

Except as expressly permitted by the merger agreement or as expressly consented to in writing by GigOptix, which consent shall not be unreasonably withheld, conditioned or delayed, until the earlier of the termination of the merger agreement or the effective time of the merger, each of Endwave and its subsidiaries must:

In addition, except as otherwise expressly provided in the merger agreement, prior to the earlier of the termination of the merger agreement or effective time of the merger, neither Endwave nor any of its subsidiaries may, without the prior written consent of GigOptix (which consent shall not be unreasonably withheld, conditioned or delayed), directly or indirectly, do any of the following:

Except as expressly permitted by the merger agreement or as expressly consented to in writing by Endwave, which consent shall not be unreasonably withheld, conditioned or delayed, until the earlier of the termination of the merger agreement or the effective time of the merger, each of GigOptix and its subsidiaries must:

In addition, except as otherwise expressly provided in the merger agreement, prior to the earlier of the termination of the merger agreement or effective time of the merger, neither GigOptix nor any of its subsidiaries may, without the prior written consent of Endwave (which consent shall not be unreasonably withheld, conditioned or delayed), directly or indirectly, do any of the following:

Until the effective time of the merger or termination of the merger agreement, Endwave and its subsidiaries have agreed that they will not, nor will they authorize or permit any of their respective officers, directors, affiliates or employees or any investment banker, attorney or other advisor or representative retained by any of them to, directly or indirectly:

An “Endwave acquisition transaction” is any transaction or series of related transactions involving:

The merger agreement, however, provides that Endwave and its board of directors: (i) may furnish information to, or participate in discussions with, any third party that has made an unsolicited acquisition proposal that the board of directors reasonably concludes may lead to an Endwave superior offer (as described below); and (ii) may participate in discussions or negotiations with any potential acquirer or approve an

unsolicited acquisition proposal if the board of directors is advised by its financial advisor that the potential acquirer submitting the acquisition proposal has the financial wherewithal to be reasonably capable of consummating the acquisition proposal, and the board of directors determines in good faith, after receiving advice from its financial advisor that the acquisition proposal is an Endwave, and after consultation with its legal counsel, that the failure to participate in discussions or negotiations with the potential acquirer or to furnish such information or approve an acquisition proposal would be inconsistent with the board of directors’ fiduciary duties under applicable law.

An “Endwave superior offer” is an unsolicited, bona fide written offer made by a third party to consummate any of the following transactions: (i) a merger or consolidation involving Endwave pursuant to which the stockholders of Endwave immediately preceding the transaction hold less than a majority of the equity interest in the surviving or resulting entity of such transaction or (ii) the acquisition by any person or group (including by way of a tender offer or an exchange offer or a two step transaction involving a tender offer followed with reasonable promptness by a cash-out merger involving Endwave), directly or indirectly, of ownership of 90% of the then outstanding shares of capital stock of Endwave, on terms that the board of directors of Endwave determines, in its reasonable judgment (based on the written advice of its financial advisor) to be more favorable to Endwave stockholders than the terms of the Merger; provided, however, that any such offer shall not be deemed to be an “Endwave superior offer” if any financing required to consummate the transaction contemplated by the offer is not committed and is not likely in the reasonable judgment of Endwave’s board of directors (based on the advice of its financial advisor) to be obtained by such third party on a timely basis.

In the event that Endwave decides to provide any information as described above, or receives any acquisition proposal (or any material amendment to an acquisition proposal previously received), it must promptly, and in any event within 24 hours, inform GigOptix in writing as to that fact and furnish to GigOptix the identity of the recipient of the information to be provided and the potential acquirer and the terms of the acquisition proposal (or material amendment).

In addition, Endwave as promptly as practicable must advise GigOptix orally and in writing of any acquisition proposal or any request for non-public information or inquiry that Endwave reasonably believes would lead to an any Endwave acquisition transaction, the material terms and conditions of such Endwave Acquisition Proposal, request or inquiry, and the identity of the person or group making any such offer or proposal relating to any Endwave acquisition transaction, request or inquiry. Endwave must keep GigOptix informed as promptly as practicable in all material respects of the status and details (including material amendments or proposed material amendments) of any offer or proposal relating to any Endwave acquisition transaction, request or inquiry.

On February 4, 2011, the Endwave board of directors unanimously adopted a resolution recommending that the Endwave stockholders adopt the merger agreement. Endwave’s board of directors has agreed to call a meeting of its stockholders to consider adoption of the merger agreement. The merger agreement does not prevent the board of directors of Endwave from withholding, withdrawing, amending or modifying its unanimous recommendation in favor of the merger if (i) an Endwave superior offer is made to Endwave and is not withdrawn, (ii) Endwave has provided written notice to GigOptix advising GigOptix that Endwave has received an Endwave superior offer, specifying the material terms and conditions of such Endwave superior offer and identifying the person or entity making such Endwave superior offer, (iii) GigOptix has not within five business days of GigOptix’ receipt of the notice of Endwave superior offer, made an offer that the board of directors of Endwave by a majority vote determines in its good faith judgment (based on the written advice of its financial advisor) to be at least as favorable to Endwave’s stockholders as the Endwave superior offer, (iv) the board of directors of Endwave concludes in good faith, after consultation with its outside counsel, that, in light of such Endwave superior offer, the failure to withhold, withdraw, amend or modify its recommendation would be inconsistent with the fiduciary obligations of the board of directors of Endwave to Endwave’s stockholders under

applicable law and (v) Endwave has not have violated any of the restrictions set forth in the merger agreement regarding non-solicitation or changing its recommendation. Endwave must provide GigOptix with at least three business days prior notice (or a lesser prior notice as provided to the members of Endwave’s board of directors but in no event less than twenty-four hours) of any meeting of Endwave’s board of directors at which Endwave’s board of directors is reasonably expected to consider any Endwave acquisition transaction.

Until the effective time of the merger or termination of the merger agreement, GigOptix and its subsidiaries have agreed that they will not, nor will they authorize or permit any of their respective officers, directors, affiliates or employees or any investment banker, attorney or other advisor or representative retained by any of them to, directly or indirectly:

A “GigOptix acquisition transaction” is any transaction or series of related transactions involving:

The merger agreement, however, provides that, prior to the effective time of the merger, GigOptix may furnish nonpublic information regarding GigOptix to, and enter into discussions or negotiations with, any person in response to an unsolicited, bona fide written offer or proposal relating to any GigOptix acquisition transaction made or received after the date of the merger agreement, which GigOptix’ board of directors determines in good faith constitutes, or is reasonably likely to result in, a GigOptix superior offer and is not withdrawn (as described below) if: (A) neither GigOptix nor any representative of GigOptix shall have failed to comply with this provision of the merger agreement; (B) the board of directors of GigOptix concludes in good faith, after consultation with outside counsel, that the failure to take such action would result in a breach of the fiduciary

duties of the board of directors of GigOptix under applicable law; (C) within 24 hours following the furnishing of any such nonpublic information to, or entering into discussions with, such person, GigOptix gives Endwave written notice of the identity of the Person and of GigOptix’ intention to furnish nonpublic information to, or enter into discussions with, such person or has furnished, or entered into discussions with, such person.

A “GigOptix superior offer” is an unsolicited, bona fide written offer made by a third party to consummate any of the following transactions: (i) a merger or consolidation involving GigOptix pursuant to which the stockholders of GigOptix immediately preceding such transaction hold less than a majority of the equity interest in the surviving or resulting entity of such transaction or (ii) the acquisition by any person or group (including by way of a tender offer or an exchange offer or a two step transaction involving a tender offer followed with reasonable promptness by a cash-out merger involving GigOptix), directly or indirectly, of ownership of 90% of the then outstanding shares of capital stock of GigOptix, on terms that the board of directors of GigOptix determines, in its reasonable judgment (based on the advice of counsel and the written advice of its financial advisor) to be an offer that the GigOptix board of directors must consider in order to fulfill its fiduciary duties; provided, however, that any such offer shall not be deemed to be an “GigOptix superior offer” if any financing required to consummate the transaction contemplated by such offer is not committed and is not likely in the reasonable judgment of GigOptix board of directors (based on the advice of its financial advisor) to be obtained by such third party on a timely basis.

The merger agreement requires GigOptix to use commercially reasonable efforts to cause the its common stock to be issued in the merger to be authorized for listing on the NYSE AMEX, subject to official notice of issuance, prior to the closing of the merger, and if that is not reasonably possible, then as soon thereafter as is reasonably possible. If within 60 days following the effective time of the merger, such shares of GigOptix common stock has not been so authorized, then the board of directors of GigOptix will use its best efforts to take further actions as appropriate to achieve such listing on NYSE AMEX, subject to official notice of issuance.

be satisfied. Approval of the listing is not a condition to the parties’ obligations to complete the merger. If any of the conditions are not satisfied, the NYSE AMEX will not approve GigOptix’ listing application, and its common will not be listed for trading on the NYSE AMEX. GigOptix’ common stock will continue to trade on the OTC Bulletin Board under the symbol “GGOX.OB” unless and until all of the conditions to trading on the NYSE AMEX have been satisfied and the shares begin officially trading on the NYSE AMEX, after which time GigOptix’ common stock will no longer be traded on the OTC Bulletin Board.

Unless waived by the parties, the respective obligations of each party to the merger Agreement to effect the merger will be subject to the fulfillment of each of the following conditions on or before the effective time of the merger:

The merger agreement may be terminated at any time prior to the effective time of the merger, whether before or after the approval and adoption of the merger agreement by Endwave stockholders:

Endwave will be obligated to pay a $1,000,000 termination fee plus certain reasonable documented expenses of GigOptix if GigOptix or Endwave terminates the merger agreement because:

The merger agreement provides that each of GigOptix and Endwave will pay its own fees and expenses in connection with the merger agreement, whether or not the merger is consummated. However, the merger agreement also provides that GigOptix and Endwave will share equally all fees and expenses, other than attorneys’ and accountants’ fees and expenses, incurred in relation to the printing and filing (with the SEC) of this proxy statement/prospectus and any amendments or supplements thereto.

Subject to applicable law, the merger agreement may be amended, modified or supplemented only by written agreement of GigOptix, Merger Sub and Endwave at any time prior to the effective time of the merger. However, after approval of the merger agreement by the Endwave stockholders, no such amendment or modification shall change the amount or form of the consideration to be received by the Endwave stockholders in the merger. Any failure of GigOptix or Merger Sub, on the one hand, or Endwave, on the other hand, to comply with any obligation, covenant, agreement or condition in the merger agreement may be waived by Endwave (with respect to any failure by GigOptix or Merger Sub) or GigOptix and Merger Sub (with respect to any failure by Endwave), respectively, only by a written instrument signed by the party granting such waiver.

The following is a summary of the opinion of Nixon Peabody LLP, counsel to GigOptix, and Cooley LLP, counsel to Endwave (collectively referred to in this discussion as “counsel”), as to the material U.S. federal income tax consequences of the mergers to certain U.S. Holders (as defined below) of Endwave common stock. Counsel’s opinions are subject to the limitations, exceptions, assumptions and conditions set forth in this discussion and in the tax opinions filed as exhibits to the registration statement of which this proxy statement/prospectus is a part. The discussion below is based upon the best judgment of counsel regarding the application of the provisions of the Code, applicable Treasury regulations, rulings, administrative pronouncements and judicial decisions as of the date hereof, all of which are subject to change or differing interpretations at any time with possible retroactive effect. GigOptix and Endwave have not sought any rulings from the Internal Revenue Service, or the IRS, with respect to the statements and conclusions reached in this summary. No assurance can be given that the IRS will agree with the views expressed in this summary, or that a court will not sustain any challenge by the IRS in the event of litigation.

This discussion addresses only those Endwave stockholders that hold their Endwave common stock as a capital asset (generally, property held for investment) within the meaning of Section 1221 of the Code. This discussion does not include any description of the tax laws of any state, local or non-U.S. government that may be applicable to a particular holder, does not consider any aspects of U.S. federal tax law other than income taxation and does not address all the U.S. federal income tax consequences that may be relevant to particular Endwave stockholders in light of their individual circumstances or to Endwave stockholders that are subject to special rules, such as:

Determining the actual tax consequences of the mergers to you may be complex. Such tax consequences will depend on your specific situation and on factors that are not within GigOptix’ and Endwave’s control. GigOptix and Endwave urge you to consult your own tax advisor concerning your particular U.S. federal, state, local and non-U.S. tax consequences of the merger.

For purposes of this discussion, the term “U.S. Holder” is used to mean a beneficial owner of Endwave common stock that is, for U.S. federal income tax purposes:

The merger of Merger Sub with and into Endwave is intended to qualify as a reorganization within the meaning of Section 368(a) of the Code, and the merger has been structured consistently with such intent.

Based on (i) the representations of GigOptix and Endwave, (ii) the merger being completed in accordance with the merger agreement, and (iii) subject to the assumptions and limitations discussed in such opinions, Nixon Peabody LLP, counsel to GigOptix, and Cooley LLP, counsel to Endwave, have provided opinions that the merger will be treated for U.S. federal income tax purposes as a reorganization within the meaning of Section 368(a) of the Code. These opinions were based upon representations and covenants made by GigOptix and Endwave, including representations in certificates of officers of GigOptix and Endwave delivered to tax counsel, and upon certain assumptions, including the absence of changes in facts or in law between the date of the issuance of such opinions and the completion of the merger. If any of those representations, covenants or assumptions is inaccurate, the tax consequences of the merger could differ materially from those summarized below. There can be no assurance that the merger will be completed. These opinions are also subject to the limitations discussed above in the first two paragraphs of this part. It is possible that the merger may not qualify as a reorganization, and the tax consequences of the merger could differ materially from those summarized below. For a further discussion, see the section entitled “Taxable Acquisition” below.

Endwave stockholders are urged to consult their own tax advisors as to the specific tax consequences to them of the merger, including any applicable federal, state, local and foreign tax consequences.

The following summary sets forth certain material U.S. federal income tax considerations for Endwave stockholders and the corporate parties to the merger if, as planned and expected, the merger is completed in accordance with the merger agreement and the conditions to the tax opinions are otherwise satisfied:

GigOptix, Merger Sub and Endwave will not recognize gain or loss solely as a result of the merger.

If you are a non-corporate holder of Endwave stock you may be subject to information reporting and backup withholding on any cash payments received in lieu of a fractional share interest in GigOptix common stock or cash payments for perfecting appraisal rights. You will not be subject to backup withholding, however, if you:

Any amounts withheld under the backup withholding rules will be allowed as a refund or credit against your U.S. federal income tax liability, provided you furnish timely the required information to the IRS.

If you receive GigOptix common stock as a result of the merger, you will be required to retain records pertaining to the merger, and you will be required to file with your U.S. federal income tax return for the year in which the merger takes place a statement setting forth certain facts relating to the merger as provided in Treasury Regulations Section 1.368-3(b).

The failure of the merger to qualify as a reorganization within the meaning of Section 368(a) of the Code would result in an Endwave stockholder recognizing gain or loss with respect to the shares of Endwave stock surrendered by such stockholder equal to the difference between the stockholder’s basis in the shares and the fair market value, as of the effective time of the merger, of the GigOptix stock received in exchange for the Endwave stock (and the cash received in lieu of a fractional share of Endwave stock). In such event, a stockholder’s aggregate basis in the GigOptix common stock so received would equal its fair market value, and such stockholder’s holding period would begin the day after the merger. The gain or loss would generally be long-term capital gain or loss, if, as of the effective date of the merger, the holding period for the Endwave stock is longer than one year. The deductibility of capital losses is subject to limitations. A dissenting stockholder who receives cash will be required to recognize gain or loss in the same manner as described above (see discussion of dissenters in a reorganization above).

The foregoing discussion is not intended to be a complete analysis or description of all potential U.S. federal income tax consequences of the merger. In addition, the discussion does not address tax consequences which may vary with, or are contingent on, your individual circumstances. Moreover, the discussion does not address any non-income tax or any foreign, state or local tax consequences of the merger. Accordingly, Endwave stockholders are urged to consult with their own tax advisor to determine the particular U.S. federal, state, local or foreign income or other tax consequences to them of the merger.

As of December 31, 2010, Endwave had a federal net operating loss carryforward of approximately $205.6 million. As of this date, Endwave also had federal research and development tax credit carryforwards of approximately $2.2 million. These net operating loss and credit carryforwards are currently expiring and will continue to do so through 2030, if not utilized.

As of December 31, 2010, Endwave had a California net operating loss carryforward of approximately $82.2 million. These state net operating losses will begin expiring in 2012, if not utilized. As of such date, Endwave also had California state research and development tax credit carryforwards and miscellaneous credit carryforwards of approximately $2.4 million. The credits will carry forward indefinitely, if not utilized.

From time to time, Endwave has commissioned third-party analyses of whether its substantial federal and state net operating loss carryforwards are subject to an annual limitation on utilization due to the ownership change provisions of Section 382 of the Internal Revenue Code and similar state provisions. Section 382 imposes a limitation on the amount of income that a corporation may offset with net operating losses and certain other tax attributes following an “ownership change.” In general, an “ownership change” is an aggregate increase of more than 50% of the ownership of a corporation (by value) over a prescribed period by the corporation’s “5% shareholders” from the lowest percentage of ownership of these shareholders in that period. In general, the prescribed ownership change testing period is the lesser of three years or the period between a prior ownership change and the given testing date. The term “5% shareholder,” for the purpose of Section 382, is a term of art and involves the operation of complex shareholder attribution, aggregation and segregation rules. If an ownership change occurs, the resulting Section 382 limitation, for each year after the ownership change, will generally be equal to the value of all the stock of the corporation (at the time of the ownership change), as adjusted under applicable rules, multiplied by a published IRS interest rate in effect at the time of the ownership change. The Section 382 limitation is subject to a number of special adjustment rules, one of which allows a Section 382 limitation to be increased by any built-in gain that economically accrued at the time of the ownership change and that is recognized within five years of such ownership change. Endwave’s analyses of its net operating loss carryforwards have been based on the best information available to Endwave and its management at the time, based in large part upon Schedules 13D and 13G and amendments thereto filed with the Securities and Exchange Commission by Endwave’s shareholders. As discussed in previous reports Endwave filed with the Securities and Exchange Commission, two hedge funds, Wood River Partners, L.P. and Wood River Partners Offshore Ltd., or Wood River Funds, accumulated a large amount of Endwave stock during 2005 without making required Schedule 13D filings with the Securities and Exchange Commission. As a result, Endwave has obtained the Wood River Funds’ share ownership information from other documents available to it, including a Securities and Exchange Commission complaint and supporting affidavits filed in such matter.

Based on Endwave’s most recent Section 382 analysis, Endwave has experienced ownership changes (within the meaning of Section 382) and, as a result of these changes, Endwave’s realizable federal net operating loss carryforward is approximately $61.8 million. Of this amount, $29.9 million is currently available to offset taxable income and this amount will increase (to the extent not utilized) by $4.4 million in 2011 and 2012 and by $1.5 million per year for the years 2013 through 2027. This limitation resulting from the above changes in ownership will result in approximately $143.8 million of federal net operating losses expiring unutilized.

Endwave also believes that its California net operating loss carryforward utilization is limited in a manner similar to its federal net operating loss carryforwards. Based on Endwave’s most recent analysis, its remaining utilizable California net operating loss carryforwards are $37.3 million. However, the California net operating loss carryforward deduction was suspended for both the 2010 and 2011 tax years for any corporate taxpayer with annual Federal taxable income, modified by any state adjustments, in excess of $300,000. As a result, Endwave will be unable to make any use of its California net operating loss carryforward in 2011 unless its annual taxable income is less than $300,000. Further, Endwave will be unable to carry back any California net operating losses

to earlier years until at least 2013. As a result of the foregoing, it is expected that a substantial portion of Endwave’s California net operating losses will expire before utilization.

Upon the consummation of Endwave’s proposed merger with GigOptix or any other acquisition of 100% of Endwave’s stock by another third party at this time, Endwave’s realizable net operating loss carryforwards would be significantly limited as a result of such merger or other acquisition. Based on Endwave’s most recent Section 382 analysis and Endwave’s estimate of the value of the shares to be issued in the merger and its balance sheet as of the closing of the merger, and assuming no further ownership changes until the date the merger is consummated, Endwave believes the completion of the merger with GigOptix would have the effect of decreasing the amount of realizable federal net operating loss carryforwards to approximately $400,000 per year, which would have the effect of reducing Endwave’s total realizable federal net operating loss carryforwards from approximately $61.8 million to $7.8 million.

In addition, based on Endwave’s most recent Section 382 analysis, a relatively small change in its ownership by 5% stockholders at this time, including an accumulation of additional shares by its existing 5% stockholders, would result in a further ownership change within the meaning of Section 382, which would have the effect of significantly limiting Endwave’s realizable net operating loss carryforwards even if the merger with GigOptix were not consummated. Changes in ownership are largely beyond Endwave’s control and thus Endwave can give no assurance that it will continue to have realizable net operating loss carryforwards whether or not the merger with GigOptix is consummated.

The following table sets forth information regarding the beneficial ownership of GigOptix’ common stock as of April 28, 2011 by:

Beneficial ownership is determined in accordance with the rules of the Securities and Exchange Commission. Applicable percentages are based on 12,374,947 shares of GigOptix common stock outstanding as of April 28, 2011, adjusted as required by such rules. As provided by such rules, shares of GigOptix common stock issuable pursuant to options to purchase or other rights to acquire shares of common stock that are exercisable within 60 days of April 28, 2011 are deemed to be both beneficially owned by the person holding such options and outstanding for the purpose of computing ownership of such person, but are not treated as outstanding for the purpose of computing the ownership of any other person. Except as indicated by footnote, to GigOptix’ knowledge, the persons named in the table have sole voting and investment power with respect to all shares of common stock shown as beneficially owned by them. The information contained in the following table is not necessarily indicative of beneficial ownership for any other purpose and the inclusion of any shares in the table does not constitute an admission of beneficial ownership of those shares.

The following table sets forth certain information regarding the ownership of our common stock as of April 28, 2011 by: (i) each of our named executive officers; (ii) each director; (iii) our executive officers and directors as a group; and (iv) all those known by us to be beneficial owners of more than five percent of our common stock. Except as otherwise indicated, the address of each of the persons set forth below is c/o Endwave Corporation, 130 Baytech Drive, San Jose, California 95134.

The following is a summary of the material terms of the capital stock of GigOptix under its amended and restated certificate of incorporation and amended and restated bylaws. This summary is not complete and is qualified in its entirety by reference to the General Corporation Law of the State of Delaware, or the DGCL, its amended and restated certificate of incorporation and amended and restated bylaws. Copies of the documents referred to in this summary may be obtained as described under “Where You Can Find More Information” on page 198 of this proxy statement/prospectus.

GigOptix is authorized to issue 51,000,000 shares of capital stock, each with a par value of $0.001, consisting of 50,000,000 shares of common stock and 1,000,000 shares of preferred stock. There were 12,374,947 shares of common stock outstanding and no shares of preferred stock outstanding as of April 28, 2011.

Notwithstanding the provisions of the DGCL, the number of authorized shares of common stock and preferred stock may, without a series vote, be increased or decreased (but not below the number of shares then outstanding) from time to time by the affirmative vote of the holders of a majority in voting power of the outstanding capital stock of GigOptix entitled to vote, voting together as a single class.

Each holder of shares of the common stock of GigOptix is entitled to attend all special and annual meetings of the stockholders of GigOptix. In addition, each such holder is entitled, together with the holders of all other classes of capital stock entitled to attend special and annual stockholder meetings (subject to the provisions of any resolutions of the board of directors granting any holders of preferred stock exclusive or special voting powers with respect to any matter), to cast one vote for each outstanding share of common stock of GigOptix held upon any matter, including the election of directors, which is properly considered and acted upon by the stockholders. Except as otherwise required by law, holders of the common stock of GigOptix, as such, are not entitled to vote on any amendment to the amended and restated certificate of incorporation (including the certificate of designation of any series of its preferred stock) that relates solely to the terms of one or more outstanding series of preferred stock of GigOptix if the holders of the affected series are entitled, either voting separately or together with the holders of one or more other affected series, to vote on such amendment under the amended and restated certificate of incorporation (including the certificate of designation of any series of its preferred stock) or pursuant to the DGCL.

The holders of the common stock of GigOptix and the holders of any class or series of stock entitled to participate with the holders of the common stock of GigOptix as to the distribution of assets in the event of any liquidation, dissolution or winding-up of the company, whether voluntary or involuntary, will become entitled to participate in the distribution of any of GigOptix’ assets remaining after it has paid, or provided for the payment of, all of its debts and liabilities and after GigOptix has paid, or set aside for payment, to the holders of any class or series of preferred stock having preference over common stock in the event of liquidation, dissolution or winding-up, the full preferential amounts, if any, to which the holders of such class or series are entitled.

Dividends may be paid on the common stock of GigOptix and on any class or series of preferred stock entitled to participate with the common stock of GigOptix as to dividends on an equal per-share basis, but only when, as and if declared by the board of directors of GigOptix. Holders of GigOptix’ common stock will be

entitled to receive any such dividends out of any assets legally available for the payment of dividends only after the provisions with respect to preferential dividends on any outstanding series of preferred stock have been satisfied and after GigOptix has complied with all the requirements, if any, with respect to redemption of, or the setting aside of sums as sinking funds or redemption or purchase accounts with respect to, any outstanding series of the preferred stock of GigOptix.

Holders of the common stock of GigOptix do not have any preemptive, cumulative voting, subscription, conversion, redemption or sinking fund rights.

Anti-Takeover Effects of Provisions of Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws

GigOptix’ amended and restated certificate of incorporation and amended and restated bylaws contain provisions that could have the effect of delaying or deferring a change in control of the company. These provisions, among other matters:

GigOptix’ amended and restated certificate of incorporation authorizes its board of directors from time to time and without further stockholder action to provide for the issuance of shares of preferred stock in one or more series, and to fix the voting powers, preferences and relative, participating, optional and other special rights, and the qualifications, limitations, and restrictions of each such series, including, but not limited to, dividend rights, liquidation preferences, conversion privileges and redemption rights. GigOptix’ board of directors will have broad discretion with respect to the creation and issuance of preferred stock without stockholder approval, subject to any applicable rights of holders of any shares of preferred stock outstanding from time to time.

The rights and privileges of holders of the common stock may be adversely affected by the rights, privileges and preferences of holders of shares of any series of preferred stock that the board of directors may designate and GigOptix may issue from time to time. Among other things, by authorizing the issuance of shares of preferred stock with particular voting, conversion or other rights, the board of directors could adversely affect the voting power of the holders of the common stock and could discourage any attempt to effect a change in control of GigOptix, even if such a transaction would be beneficial to the interests of the stockholders of GigOptix.

GigOptix and Endwave are corporations incorporated under the laws of the State of Delaware. Following the merger, equity holders of Endwave, whose rights are currently governed by the DGCL and Endwave’s amended and restated certificate of incorporation and amended and restated by-laws, will become holders of GigOptix common stock, and their rights as such will be governed by the DGCL, the amended and restated certificate of incorporation of GigOptix and the by-laws of GigOptix, as amended.

The following is a summary of the material differences between the rights of a holder of:

The following summary does not purport to be a complete statement of the rights of holders of GigOptix common stock or Endwave common stock. This discussion is qualified in its entirety by the DGCL, and the governing instruments of Endwave and GigOptix. Although Endwave and GigOptix believe that this summary covers the material differences between the governing corporate documents of the three companies, this summary may not contain all of the information that is important to you. Stockholders of Endwave and GigOptix should carefully read this entire proxy statement/prospectus and the other documents referred to in this proxy statement/prospectus for a more complete understanding of the differences between being a common stockholder of GigOptix and being a common stockholder of Endwave. See also “Description of Company Capital Stock.” Copies of the documents referred to in this summary may be obtained as described under “Where You Can Find More Information” on page 198 of this proxy statement/prospectus.

GigOptix’ authorized capital stock will consist of 51,000,000 shares, of which 50,000,000 shares are common stock, par value $0.001 per share, and 1,000,000 shares are preferred stock, par value $0.001 per share.

As of April 28, 2011, 12,374,947 shares of GigOptix common stock were outstanding and no shares of GigOptix preferred stock were outstanding. Based on the numbers of shares of Endwave common stock outstanding as of April 28, 2011, GigOptix anticipates that approximately 21,564,527 shares of GigOptix common stock will be outstanding following completion of the merger, without taking into account shares of GigOptix common stock subject to issuance after the merger pursuant to options, warrants, restricted units and other rights to acquire GigOptix common stock.

Endwave’s authorized capital stock consists of 55,000,000 shares, 50,000,000 of which are common stock, par value $0.001 per share, and 5,000,000 shares of which are preferred stock, par value $0.001 per share.

As of April 28, 2011, 9,892,120 shares of Endwave common stock and no shares of Endwave preferred stock were outstanding.

Under the DGCL, GigOptix’ board of directors may declare and pay dividends on the common stock out of surplus or current net profits. During the time that any series of GigOptix’ preferred stock is outstanding, if the terms of the series so provide, no dividends may be declared or paid by GigOptix’ board of directors on Company common stock, unless dividends on all outstanding shares of the relevant series of GigOptix’ preferred stock for the current and all past dividends periods have been declared and paid or provision made for the payment of those dividends. In addition, GigOptix’ ability to pay any dividends on its common stock is subject to applicable provisions of state law and to the terms of its credit agreements.

Under the DGCL, the Endwave board of directors may declare and pay dividends on the common stock out of surplus or current net profits. During the time that any series of Endwave preferred stock is outstanding, the preferred stock is not entitled to receive dividends, except as declared, and at such rates per share, as may be specified by Endwave’s board of directors. In addition, Endwave’s ability to pay any dividends on its common stock is subject to applicable provisions of state law and to the terms of its credit agreements.

Subject to the voting rights of holders of any then-outstanding preferred stock of GigOptix, each share of GigOptix common stock is entitled to one vote on each matter submitted to a vote of the stockholders of GigOptix. Shares of GigOptix common stock are not entitled to cumulative voting rights.

Each share of Endwave common stock is entitled to one vote on each matter submitted to a vote of the stockholders of Endwave. Any outstanding Endwave preferred stock may be voted equally with the shares of Endwave common stock and not as a separate class. Shares of Endwave common stock are not entitled to cumulative voting rights.

The size of the GigOptix’ board of directors is determined by resolution of GigOptix’ board of directors, subject to requirements of GigOptix’ amended and restated By-laws. Under GigOptix’ amended and restated certificate of incorporation, the number of directors constituting GigOptix’ board of directors may not be fewer than two nor more than ten. GigOptix’ amended and restated certificate of incorporation provides that GigOptix’ board of directors is to be divided into three classes of directors, with the classes to be as nearly equal in number as possible, subject to the special rights of holders of any class or series of stock to elect directors. GigOptix’ board of directors is authorized to include seven members (five of which are currently in office), divided into three classes serving staggered three-year terms. Upon the expiration of the initial term of each class, the nominees for that class will be elected for a term of three years to succeed the directors whose terms of office expire.

The size of the Endwave board of directors is determined by resolution of the Endwave board of directors. The Endwave board of directors currently is composed of six members. The directors hold office until the next special meeting or until such director’s successor has been elected and qualified. Endwave’s amended and restated certificate of incorporation provides that Endwave’s board of directors is to be divided into three classes of directors.

The directors of GigOptix may be removed only for cause by the affirmative vote of the holders of two-thirds of the shares of the capital stock of GigOptix.

The directors of Endwave may be removed only for cause by a majority of the voting power of the corporation entitled to vote at an election of directors.

Vacancies and newly-created directorships will be filled exclusively pursuant to a resolution adopted by the board of directors.

Vacancies on the board of directors resulting from death, resignation, disqualification, removal or other causes and any newly created directorships resulting from any increase in the number of directors, will, unless the Endwave board of directors determines by resolution that any such vacancy or newly created directorship may be filled by the stockholders, except as otherwise provided by law, be filled only by the affirmative vote of a majority of the directors then in office, even though less than a quorum of the board of directors, and not by the Endwave stockholders.

GigOptix’ amended and restated certificate of incorporation does not provide for appraisal rights. The DGCL provides for appraisal rights only in the case of a merger or consolidation of a corporation where the petitioning stockholder does not consent to the transaction. No appraisal rights are available where the corporation is to be the surviving corporation and a vote of its stockholders is not required under the DGCL (except for a short form merger pursuant to Section 253 of the DGCL). There also are no appraisal rights, unless otherwise provided in a corporation’s certificate of incorporation, for shares of stock listed on a national securities exchange, or held by more than 2,000 holders of record, unless such stockholders would be required to accept any consideration other than shares of stock of the surviving corporation, shares of another corporation so listed or held by such number of holders of record, cash instead of fractional shares of such stock, or any combination of the foregoing. Unless otherwise provided in a corporation’s certificate of incorporation, stockholders are not entitled under Delaware law to appraisal rights upon a sale of all or substantially all of the assets of the corporation not made in the usual and regular course of its business.

Endwave’s amended and restated certificate of incorporation does not provide for appraisal rights. The provisions of the DGCL with respect to appraisal rights, as described above, apply to Endwave.

Under the DGCL, unless a greater vote is required by GigOptix’ amended and restated certificate of incorporation, an amendment to GigOptix’ amended and restated certificate of incorporation requires the approval of GigOptix’ board of directors and the approval of the holders of a majority of the outstanding

GigOptix common stock entitled to vote on the amendment and the holders of a majority of the outstanding stock of each class entitled to vote as a class on such amendment. The GigOptix’ amended and restated certificate of incorporation does not require a greater than majority vote, except for the following provisions, which require the affirmative vote of the holders of two-thirds of the shares of GigOptix in order to amend the following provisions of the certificate of incorporation: (1) amendments to certificate of incorporation, (2) limitation on director liability, (3) indemnification, (4) directors, (5) special voting requirements, and (6) special meeting of stockholders.

GigOptix’ amended and restated certificate of incorporation provides that the holders of GigOptix common stock are not entitled to vote on any amendment to GigOptix’ amended and restated certificate of incorporation, including any certificate of designation relating to any series of GigOptix’ preferred stock, that relates solely to the terms of one or more outstanding series of GigOptix’ preferred stock if the holders of the affected series are entitled, either voting separately or together with the holders of one or more other such series, to vote on the amendment pursuant to GigOptix’ amended and restated certificate of incorporation, including any certificate of designation relating to any series of GigOptix’ preferred stock, or pursuant to the DGCL.

GigOptix’ amended and restated certificate of incorporation and amended and restated bylaws provide that GigOptix’ amended and restated bylaws may be amended or new bylaws adopted by the affirmative vote of a majority of directors then in office, subject to the power of the stockholders.

Under the DGCL, unless a greater vote is required by Endwave’s amended and restated certificate of incorporation, an amendment to Endwave’s amended and restated certificate of incorporation requires the approval of Endwave’s board of directors and the approval of the holders of a majority of the outstanding Endwave common stock entitled to vote on the amendment and the holders of a majority of the outstanding stock of each class entitled to vote as a class on such amendment. Endwave’s amended and restated certificate of incorporation does not require a greater than majority vote.

Endwave’s amended and restated bylaws provide that Endwave’s amended and restated bylaws may be altered or amended or new bylaws adopted by the affirmative vote of at least sixty-six and two-thirds percent of the voting power of all of the then-outstanding shares of the capital stock of Endwave entitled to vote. Endwave’s board of directors also has the power to adopt, amend, or repeal the amended and restated bylaws

GigOptix’ amended and restated bylaws provide that annual stockholder meetings are held on a date to be determined by the board of directors. GigOptix’ amended and restated certificate of incorporation provides that special meetings of stockholders may be called at any time and for any purpose by the chief executive officer, the president, the chairman of the board of directors, or by vote of a majority of the board of directors. Further, a special meeting of the stockholders may be called if the holders of not less than twenty-five percent of all the votes entitled to be cast on the issue proposed to be considered at such special meeting have dated, signed and delivered to the secretary one or more written demands for such meeting.

Endwave’s amended and restated bylaws provide that annual stockholder meetings are held on a date to be determined by the board of directors. Endwave’s amended and restated certificate of incorporation provides that special meetings of stockholders may be called the chairman of the board of directors, the chief executive officer, the board of directors pursuant to a resolution adopted by a majority of the total number of authorized directors

(whether or not there exist any vacancies in previously authorized directorships at the time any such resolution is presented to the board of directors for adoption) or by the holders of the shares entitled to cast not less that ten percent of the votes at the meeting.

GigOptix’ amended and restated bylaws establish advance notice procedures for stockholders to make nominations of candidates for election as directors at any annual or special meeting of stockholders or to present any other business for consideration at any annual stockholder meetings.

The nominating procedures require a stockholder to submit written notice to GigOptix secretary not fewer than 60 days nor more than 90 days before the anniversary date of the prior year’s annual meeting with respect to an election to be held at an annual meeting, or by the close of business on the seventh business day following the date on which notice is first given with respect to an election to be held at a special meeting. The notice must include (a) the name and address of the stockholder who intends to make a nomination; (b) a representation that the stockholder is entitled to vote at such meeting and a statement of the number of shares of GigOptix that are beneficially owned by the stockholder; (c) a representation that the stockholder intends to appear in person or by proxy at the meeting to nominate the person or persons specified in the notice; (d) as to each person the stockholder proposes to nominate for election or re-election as a director, the name and address of such person and such other information regarding such nominee as would be required in a proxy statement filed pursuant to the proxy rules of the Securities and Exchange Commission had such nominee been nominated by the board of directors, and a description of any arrangements or understandings, between the stockholder and such nominee and any other persons (including their names), pursuant to which the nomination is to be made; and (e) the consent of each such nominee to serve as a director if elected. The board of directors or the chairman of a stockholders’ meeting at which directors are to be elected may disregard the nomination of any person not made in compliance with the forgoing procedure.

For a stockholder to properly bring business before an annual meeting, the procedures require a stockholder to submit written notice to GigOptix secretary not fewer than 60 nor more than 90 days prior to the anniversary date of the prior year’s annual meeting; provided that if the date of the annual meeting is advanced more than 30 days prior to or delayed by more than 30 days after the anniversary of the preceding year’s annual meeting, notice by the stockholder must be delivered not later than the close of business on the later of (i) the 90th day prior to such annual meeting or (ii) the tenth day following the day on which the notice of the date of the annual meeting was mailed or such public disclosure was made. The board of directors of the chairman of an annual meeting of the stockholders may disregard the business to be transacted if either determines that (x) a proposal does not constitute proper business to be transacted at the meeting or (y) business was not properly brought before the meeting in accordance with the foregoing procedure.

In addition to the procedures set forth above, a stockholder will also be required to comply with all applicable requirements of the Exchange Act and the rules and regulations promulgated thereunder.

Endwave’s amended and restated bylaws establish advance notice procedures for stockholders to make nominations of candidates for election as directors at any annual or special meeting of stockholders or to present any other business for consideration at any annual stockholder meetings.

For nominations or other business to be properly brought before an annual meeting by a stockholder pursuant to Endwave’s amended and restated bylaws, (i) the stockholder must have given timely notice thereof in writing to the Secretary of the corporation, (ii) the business must be a proper matter for stockholder action under the DGCL, (iii) if the stockholder, or the beneficial owner on whose behalf any proposal or nomination is made, has provided the corporation with a solicitation notice, the stockholder or beneficial owner must, in the case of a

proposal, have delivered a proxy statement and form of proxy to holders of at least the percentage of the Endwave’s voting shares required under applicable law to carry any such proposal, or, in the case of a nomination or nominations, have delivered a proxy statement and form of proxy to holders of a percentage of the corporation’s voting shares reasonably believed by such stockholder or beneficial owner to be sufficient to elect the nominee or nominees proposed to be nominated by such stockholder, and must, in either case, have included in the solicitation notice in the materials, and (iv) if no solicitation notice relating thereto has been timely provided, the stockholder or beneficial owner proposing such business or nomination must not have solicited a number of proxies sufficient to have required the delivery of such a solicitation notice under Endwave’s amended and restated bylaws.

To be timely, a stockholder’s notice shall be delivered to the Secretary at the principal executive offices of the corporation not later than the close of business on the 90th day nor earlier than the close of business on the 120th day prior to the first anniversary of the preceding year’s annual meeting; provided, however, that in the event that the date of the annual meeting is advanced more than 30 days prior to or delayed by more than 30 days after the anniversary of the preceding year’s annual meeting, notice by the stockholder to be timely must be so delivered not earlier than the close of business on the 120th day prior to such annual meeting and not later than the close of business on the later of the 90th day prior to the annual meeting or the 10th day following the day on which public announcement of the date of such meeting is first made. In no event shall the public announcement of an adjournment of an annual meeting commence a new time period for the giving of a stockholder’s notice as described above.

The stockholder’s notice shall set forth: (A) as to each person whom the stockholder proposed to nominate for election or reelection as a director all information relating to such person that is required to be disclosed in solicitations of proxies for election of directors in an election contest, or is otherwise required, in each case pursuant to Regulation 14A under the 1934 Act and Rule 14a-4(d) thereunder (including such person’s written consent to being named in the proxy statement as a nominee and to serving as a director if elected); (B) as to any other business that the stockholder proposes to bring before the meeting, a brief description of the business desired to be brought before the meeting, the reasons for conducting such business at the meeting and any material interest in such business of such stockholder and the beneficial owner, if any, on whose behalf the proposal is made; and (C) as to the stockholder giving the notice and the beneficial owner, if any, on whose behalf the nomination or proposal is made (i) the name and address of such stockholder, as they appear on the corporation’s books, and of such beneficial owner, (ii) the class and number of shares of the corporation that are owned beneficially and of record by such stockholder and such beneficial owner, and (iii) whether either such stockholder or beneficial owner intends to deliver a proxy statement and form of proxy to holders of, in the case of the proposal, at least the percentage of the corporation’s voting shares required under applicable law to carry the proposal or, in the case of a nomination or nominations, a sufficient number of holders of the corporation’s voting shares to elect such nominee or nominees.

The DGCL provides that, unless otherwise provided in the certificate of incorporation, any action required to be taken or which may be taken at any annual or special meeting of stockholders of a corporation may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing, setting forth the action so taken, is signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted. GigOptix’ amended and restated bylaws provide that, any action that is required or permitted to be taken by the stockholders of GigOptix at any annual or special meeting of stockholders may be effected by written consent of stockholders in lieu of a meeting, if written consents signed and dated by holders of not less than the minimum number of votes that would be necessary to authorize the action at a meeting at which all shares of stock of GigOptix entitled to vote were present and voted are delivered to GigOptix within 60 days of the earliest dated consent is so delivered.

Endwave’s amended and restated bylaws provides that no action may be taken by its stockholders by written consent.

The DGCL provides that a corporation may indemnify its officers, directors, employees and agents against liabilities and expenses incurred in proceedings if the person acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation and, with respect to any criminal action, had no reasonable cause to believe that the person’s conduct was unlawful. The DGCL further provides that no indemnification is available in respect of a claim as to which the person has been adjudged to be liable to the corporation, unless and only to the extent that a court determines that in view of all the circumstances, such person is fairly and reasonably entitled to indemnity for such expenses that the court deems proper. Under the DGCL, a Delaware corporation must indemnify its present or former directors and officers against expenses (including attorneys’ fees) actually and reasonably incurred to the extent that the officer or director has been successful on the merits or otherwise in defense of any action, suit or proceeding brought against him or her by reason of the fact that he or she is or was a director or officer of the corporation.

GigOptix’ amended and restated certificate of incorporation provide that GigOptix will indemnify and advance expenses to, and hold harmless, to the fullest extent permitted by applicable law as it presently exists or may hereafter be amended, any person who was or is made or is threatened to be made a party or is otherwise involved in any action, suit or proceeding, whether criminal, civil, administrative or investigative, by reason of the fact that he, or a person for whom he is the legal representative, is or was a director or officer of GigOptix or, while a director or an officer of GigOptix, is or was serving at the request of GigOptix as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust, enterprise or nonprofit entity, including service with respect to employee benefit plans, against all liability and loss suffered and expenses (including attorneys’ fees) reasonably incurred by such person. GigOptix will not be obligated to indemnify such person in connection with a proceeding commenced by such person unless GigOptix’ board of directors has authorized the commencement of such a proceeding.

The provisions of the DGCL with respect to indemnification of directors and officers, as described above, apply to Endwave.

Endwave’s amended and restated certificate of incorporation provides that Endwave will indemnify its directors and executive officers to the fullest extent not prohibited by the DGCL or any other applicable law.

The DGCL provides that a corporation may include in its certificate of incorporation a provision eliminating the liability of a director to the corporation or its stockholders for monetary damages for a breach of the director’s fiduciary duties, except liability for any breach of the director’s duty of loyalty to the corporation’s stockholders, for acts or omissions not in good faith or that involve intentional misconduct or knowing violation of law, under Section 174 of the DGCL (which deals generally with unlawful payments of dividends, stock repurchases and redemptions), and for any transaction from which the director derived an improper personal benefit.

GigOptix’ amended and restated certificate of incorporation provides that no director of GigOptix will be personally liable to GigOptix or its stockholders for monetary damages for any breach of fiduciary duty as a director.

If the DGCL is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of the corporation shall be eliminated or limited to the fullest extent permitted by the DGCL, as so amended. No repeal or modification of this provision of the amended and restated certificate of incorporation will adversely affect any right or protection of any director of GigOptix existing at the date of such modification or repeal or create any liability or adversely affect any such right or protection for any acts or omissions of such director occurring before such modification or repeal.

The provisions of the DGCL with respect to limitation on director liability, as described above, apply to Endwave.

Endwave’s amended and restated certificate of incorporation provides that its director shall not be personally liable to Endwave or its stockholders for monetary damages for any breach of fiduciary duty as a director, except for liability (i) for any breach of the director’s duty of loyalty to Endwave or its stockholders, (ii) for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) for any transaction from which the director derived an improper personal benefit. If the DGCL is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director shall be eliminated or limited to the fullest extent permitted by the DGCL.

GigOptix has no agreements or arrangements with any of its stockholders with respect to the transfer of its common stock.

Endwave has no agreements or arrangements with any of its stockholders with respect to the transfer of its common stock.

GigOptix’ amended and restated certificate of incorporation and amended and restated bylaws do not provide for restrictions on transfers of shares of Company common stock.

Endwave’s amended and restated certificate of incorporation and amended and restated bylaws do not provide for restrictions on transfers of shares of Endwave common stock.

GigOptix’ amended and restated certificate of incorporation does not provide for the dissolution of the corporation. Under Section 275 of the DGCL, a corporation may be dissolved upon the adoption of a resolution to that effect by a majority of the board, and the approval of a majority of the outstanding stock entitled to vote.

Endwave’s amended and restated certificate of incorporation does not provide for the dissolution of the corporation. The provisions of the DGCL relating to corporate dissolution, as described above, apply to Endwave.

Approval of Adjournment or Postponement of the Special Meeting of Endwave Stockholders

If Endwave fails to receive a sufficient number of votes to approve the terms of the merger, Endwave may propose to adjourn or postpone Endwave’s special meeting, whether or not a quorum is present, until a later time for the purpose of soliciting additional proxies to approve the terms of the merger. Endwave currently does not intend to propose adjournment or postponement at Endwave’s special meeting if there are sufficient votes to adopt the merger agreement. If approval of the proposal to adjourn or postpone Endwave’s special meeting for the purpose of soliciting additional proxies is submitted to Endwave’s stockholders for approval, such approval requires the affirmative vote of a majority of the votes cast at Endwave’s special meeting by the holders of shares of Endwave common stock present or represented by proxy and entitled to vote thereon.

The Endwave board unanimously recommends that the Endwave stockholders vote “FOR” the proposal to adjourn or postpone Endwave’s special meeting, if necessary, to solicit additional proxies if there are not sufficient votes in favor of the proposal regarding the adoption of the merger agreement.

It is not expected that Endwave will hold an annual meeting for stockholders for 2011 unless the merger transaction is not completed. In order to be considered for inclusion in the proxy statement for the 2011 annual meeting of stockholders, should one be held, stockholder proposals must have been submitted in writing by February 11, 2011 to Endwave’s Corporate Secretary at 130 Baytech Drive, San Jose, California, 95134. If you wish to submit a proposal that is not to be included in next year’s proxy materials or nominate a director, you must do so no earlier than March 24, 2011, and no later than by April 23, 2011, or within such other period as is specified in Endwave’s bylaws. You are advised to review Endwave’s bylaws, which contain additional requirements concerning stockholder proposals and director nominations.

As of the date of this proxy statement/prospectus, Endwave’s board of directors is not aware of any matter that will be presented for consideration at the Endwave special meeting other than as described in this proxy statement/prospectus.

Nixon Peabody LLP, counsel to GigOptix, will issue a legal opinion concerning the validity of the GigOptix common stock offered by this proxy statement/prospectus and the federal income tax consequences of the merger.

We have audited the accompanying consolidated balance sheet of GigOptix, Inc. (a Delaware corporation) and subsidiaries as of December 31, 2010, and the related consolidated statements of operations, stockholders’ equity and comprehensive loss and cash flows for the year then ended. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of GigOptix, Inc. and subsidiaries as of December 31, 2010, and the results of their operations and their cash flows for the year then ended in conformity with accounting principles generally accepted in the United States of America.

In our opinion, the consolidated balance sheet as of December 31, 2009 and the related consolidated statements of operations, stockholders’ equity and comprehensive loss, and cash flows for the year then ended present fairly, in all material respects, the financial position of GigOptix, Inc. and its subsidiaries at December 31, 2009, and the results of their operations and their cash flows for the year ended December 31, 2009, in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audit. We conducted our audit of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States).

An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audit provide a reasonable basis for our opinion.

The accompanying consolidated financial statements have been prepared assuming the Company will continue as a going concern. As described in Note 1 in the Notes to the Consolidated Financial Statements included in the Annual Report on Form 10-K for the year ended December 31, 2009, the Company has suffered recurring losses and negative cash flows from operations that raise substantial doubt about its ability to continue as a going concern. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

We are a leading provider of electronic engines for the optically connected digital world and other advanced RF applications. We incorporated in March 2008 under the laws of the state of Delaware and upon completion of the merger of GigOptix LLC and Lumera Corporation (“Lumera”) on December 9, 2008, became a public reporting company on December 10, 2008. We are a successor registrant to Lumera.

Our business operations focus on the specification, design, development and sale of analog semiconductor integrated circuits, or ICs, multi-chip module solutions, or MCMs, and polymer modulators. We believe we are an industry leader in the fast growing market for electronic solutions that enable high-bandwidth optical connections found in telecommunications (“telecom”) systems, data communications (“data-com”) and storage systems, and, increasingly, in consumer electronics and computing systems.

We were formed in March 2008 in order to facilitate a combination between GigOptix LLC and Lumera. Before the combination, which was effected by two mergers, which is referred to collectively as the “Merger”, we were a wholly-owned subsidiary of Lumera, and were formed to complete the Merger. We had no operations or material assets before the Merger. As a result of the transaction set forth in the Agreement and Plan of Merger, dated as of March 27, 2008, among Lumera, GigOptix LLC, Galileo Merger Sub G, LLC and Galileo Merger Sub L, Inc., (the “Lumera Merger Agreement”) on December 9, 2008, the Merger was completed and Lumera and GigOptix LLC became our wholly owned subsidiaries and we became the successor public registrant to Lumera.

At the time of the Merger, Lumera was a developer of high performance proprietary electro-optic polymer materials and products based on these materials for various electro-optic applications and GigOptix LLC was a fabless semiconductor company specializing in the specification, design, development and sale of integrated circuits and electronic multi-chip module solutions.

Prior to the Merger, GigOptix LLC was an Idaho limited liability company, headquartered in Palo Alto, California. GigOptix LLC was the successor company of iTerra Communications LLC, or “ iTerra”, which was founded in 2000. In July 2007, as part of a reorganization plan, iTerra formed GigOptix LLC, a wholly-owned subsidiary. All of the assets and liabilities of iTerra, with the exception of the $45.8 million of debt and accrued interest due to iTerra’s primary member, were transferred to GigOptix LLC, along with all of iTerra’s operations and intellectual property.

In January 2008, GigOptix LLC acquired Helix AG, or Helix, a company based in Switzerland, which designed and sold optical receiver transmitter array products consisting of driver and receiver arrays for 4-channel and 12-channel modules running at 3Gbps to 10Gbps per channel. The acquisition of Helix enabled GigOptix LLC to expand its product offering into short reach devices and systems.

In November 2009 we acquired ChipX, Incorporated (“ChipX”), a leading independent fabless supplier specializing in analog and mixed signal custom ASICs. ChipX became our subsidiary as a result of the acquisition.

The accompanying consolidated financial statements have been prepared assuming that we will continue as a going concern, which contemplates the realization of assets and the liquidation of liabilities in the normal

course of business. We have incurred negative cash flows from operations since inception. For the years ended December 31, 2010 and 2009, the Company incurred net losses of $4.4 million and $10.0 million, respectively, and cash outflows from operations of $3.8 million and $4.1 million, respectively. As of December 31, 2010 and 2009, we had an accumulated deficit of $73.4 million and $69.0 million, respectively.

Our ability to continue as a going concern is dependent on many events outside of our direct control, including, among other things; obtaining additional financing either privately or through public markets and consumers’ purchasing its products in substantially higher volumes. During 2010 we raised approximately $3.9 million in additional equity capital from institutional investors which stabilized our cash position. We had a cash balance at December 31, 2010 of approximately $4.5 million. We have used some of the equity capital to substantially reduce our outstanding accounts payable and accrued expenses balances. In addition, we have access to a line of credit with Silicon Valley Bank which enables us to borrow up to $3 million based on 80% of eligible invoiced amounts to customers. During fiscal 2010 we had a net loss of $4.4 million. We also were close to breakeven in the fourth quarter of 2010, incurring a loss of $97,000, on an operating income basis. Additionally, our pending merger with Endwave will upon closing provide us with additional cash and equivalents which will mitigate any near-term liquidity issues. Based on these events and factors we believe the company can continue as a going concern for at least the next 12 months.

Certain prior-year amounts in the consolidated financial statements and the notes thereto have been reclassified where necessary to conform to the current presentation. These reclassifications did not affect the prior period stockholders’ equity (deficit), net loss or net cash used in operating activities.

In connection with certain borrowings we had made from both Bridge Bank and Agility Capital, we issued warrants. Certain provisions in the warrant agreements provided for “down round” protection if we raised equity capital at a per share price which was less than the per share price of the warrants. Such down round protection requires us to classify the value of the warrants as a liability and record changes in the fair value through the statement of operations each reporting period until the warrants are either exercised or cancelled. We reclassified the fair value of these warrants from equity to non-current liabilities during the fourth quarter of 2010 and recorded expense of $87,000 as the change in value of the warrants in the fourth quarter of 2010, that should have been recorded in prior quarters of 2010. We determined the impact to the prior periods was not material.

Our fiscal year ends on December 31. The consolidated financial statements include our accounts and our wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates, judgments and assumptions that affect the reported amount of assets, liabilities, revenues and expenses and related disclosures of contingent assets and liabilities. On an on-going basis, we evaluate our estimates, including those related to allowances for doubtful accounts, inventory write-downs, valuation of long-lived assets, including property and equipment and identified intangible assets, valuation of deferred taxes and contingencies. In addition, we use assumptions when employing the Black-Scholes option valuation model to calculate the fair value of stock options and warrants granted; and assumptions when employing the Monte Carlo simulation to estimate the fair value of our warrant liability. We

base our estimates of the carrying value of certain assets and liabilities on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, when these carrying values are not readily available from other sources. Actual results could differ from these estimates.

We operate in a dynamic industry and, accordingly, our business can be affected by a variety of factors. For example, changes in any of the following areas could have a negative effect on us in terms of our future financial position, results of operations or cash flows: a downturn in the overall semiconductor industry or communications semiconductor market; regulatory changes; fundamental changes in the technology underlying telecommunications products or incorporated in customers’ products; market acceptance of our products under development; litigation or other claims against us; the hiring, training and retention of key employees; integration of businesses acquired by us; successful and timely completion of product development efforts; and new product introductions by competitors.

Our financial instruments consist primarily of cash and cash equivalents, accounts receivable, accounts payable and common stock warrants. We believe that the carrying amounts of the financial instruments approximate their respective fair values. When there is no readily available market data, fair value estimates may be made by us, which may not necessarily represent the amounts that could be realized in a current or future sale of these assets.

Revenue from sales of optical modulator drivers and receivers, MCMs, and other products is recognized when persuasive evidence of a sales arrangement exists, transfer of title occurs, the sales price is fixed or determinable and collection of the resulting receivable is reasonably assured. Provisions are made for warranties at the time revenue is recorded. See Note 12—Commitments and Contingencies for further detail related to the warranty provision.

Customer purchase orders are generally used to determine the existence of an arrangement. Transfer of title and risk of ownership occur based on defined terms in customer purchase orders, and generally pass to the customer upon shipment, at which point goods are delivered to a carrier. There are no formal customer acceptance terms or further obligations, outside of our standard product warranty. We assess whether the sales price is fixed or determinable based on the payment terms associated with the transaction. Collectability is assessed based primarily on the credit worthiness of the customer as determined through ongoing credit evaluations of the customer’s financial condition, as well as consideration of the customer’s payment history.

Revenue generated from product development projects, research and development cost reimbursement contracts and cost plus fixed fee type contracts for the United States government, is recorded using the percentage of completion method measured on a cost-incurred basis. Changes in contract performance, contract conditions, and estimated profitability, including those arising from contract penalty provisions and final contract settlements, may result in revisions to costs and revenues and are recognized in the period in which the revisions are determined. Profit incentives are included in revenue when realization is assured. Losses, if any, are recognized in full as soon as identified. Losses occur when the estimated direct and indirect costs to complete the contract exceed the unrecognized revenue on the contract. We evaluate the reserve for contract losses on a contract-by-contract basis. No losses have been incurred on any contracts to date.

In the year ended December 31, 2009, we used provisional rates to bill amounts under government contracts. In March 2010, we received approved rates by the government for 2009 that were lower than those that had been used for billing purposes during each of the four quarters in fiscal 2009. As a result of the change in estimated billing rates, we recorded a reduction in revenue received under government contracts of $1.3 million and reflected such amount as a change in estimate and recorded it in the quarter ended December 31, 2009.

Unbilled accounts receivables, included as a component of accounts receivable on the balance sheet, comprises amounts of revenue recognized on contracts that we have not yet billed to a customer because the amounts were not contractually billable at the balance sheet date. We were contractually able to bill 91% of the unbilled accounts receivable balance at December 31, 2010 within 45 days of the year-end.

We maintain an allowance for doubtful accounts for losses that we estimate will arise from our customers’ inability to make required payments for goods and services purchased from us. We make our estimates of the uncollectibility of our accounts receivable by analyzing historical bad debts, specific customer creditworthiness and current economic trends. Once an account is deemed unlikely to be fully collected, we write down the carrying value of the receivable to the estimated recoverable value, which results in a charge to general and administrative expense, which decreases our profitability.

We consider all highly liquid investments with an original maturity of 90 days or less at the date of purchase to be cash equivalents. Cash and cash equivalents are maintained at various financial institutions.

Financial instruments that potentially subject us to significant concentrations of credit risk consist primarily of cash and accounts receivable. We maintain cash with various financial institutions. At any time, amounts held at any single financial institution may exceed federally insured limits. We believe that the concentration of credit risk in our accounts receivable is substantially mitigated by our credit evaluation process and the relatively short collection terms. We perform ongoing credit evaluations of our customers’ financial condition and limit the amount of credit extended when deemed necessary but generally we require no collateral.

As of December 31, 2010, two customers accounted for 25% and 17% of total accounts receivable. As of December 31, 2009, two customers accounted for 13% and 12% of total accounts receivable. For the year ended December 31, 2010, two customers accounted for 13% and 11% of total revenue, respectively. For the year ended December 31, 2009, three customers accounted for 24%, 23% and 10% of total revenue.

Inventories are stated at the lower of cost or market value, with cost computed on an average-cost basis. Cost includes labor, material and overhead costs, including product and process technology costs. Determining fair market value of inventories involves numerous judgments, including projecting average selling prices and sales volumes for future periods and costs to complete products in work in process inventories. As a result of this analysis, when fair market values are below costs, we record a charge to cost of revenue in advance of when the inventory is scrapped or sold.

We evaluate our ending inventories for excess quantities and obsolescence on a quarterly basis. This evaluation includes analysis of historical and forecasted sales levels by product against inventories on-hand. Inventories on-hand in excess of forecasted demand are reviewed by management to determine if a writedown is

required. In addition, we write-off inventories that are considered obsolete. Obsolescence is determined from several factors, including competitiveness of product offerings, market conditions and product life cycles when determining obsolescence. Excess and obsolete inventories are charged to cost of revenue and a new, lower-cost basis for that inventory is established.

Our inventories include high-technology parts that may be subject to rapid technological obsolescence and which are sold in a highly competitive industry. If actual product demand or selling prices are less favorable than forecasted amounts, we may be required to take additional inventory write-downs.

Property and equipment, including leasehold improvements, are recorded at cost and depreciated using the straight-line method over their estimated useful lives. Leasehold improvements are depreciated over the lesser of their estimated useful lives or the remaining lease term.

Long-lived assets include equipment, furniture and fixtures, leasehold improvements and intangible assets. When events or changes in circumstances indicate that the carrying amount of long-lived assets may not be recoverable, we test for recoverability by comparing the estimate of undiscounted cash flows to be generated by the assets against the assets’ carrying amount. If the carrying value exceeds the estimated future cash flows, the assets are considered to be impaired. The amount of impairment equals the difference between the carrying amount of the assets and their fair value. Factors we consider important that could trigger an impairment review include continued operating losses, significant negative industry trends, significant underutilization of the assets and significant changes in how we plan to use the assets.

Intangible assets are amortized on a straight-line basis over their estimated economic lives of three to seven years for existing technology; five to sixteen years for patents; one year for order backlog; ten years for trade name; and three to eight years for customer relationships.

Goodwill is recorded when the purchase price of an acquisition exceeds the fair value of the net purchased tangible and intangible assets acquired and is carried at cost. Goodwill is not amortized, but is reviewed annually for impairment. We perform our annual goodwill impairment analysis in the fourth quarter of each year or more frequently if we believe indicators of impairment exist. Factors that we consider important which could trigger an impairment review include the following:

The performance of the test involves a two-step process. The first step requires a comparison of the fair value of the reporting unit to its net book value, including goodwill. The fair value of the reporting unit is determined based on the present value of estimated future cash flows of the reporting unit. A potential

impairment exists if the fair value of the reporting unit is lower than its net book value. The second step of the process is only performed if a potential impairment exists, and it involves determining the difference between the fair values of the reporting unit’s net assets, other than goodwill, and the fair value of the reporting unit, and, if the difference is less than the net book value of goodwill, an impairment charge is recorded. In the event that we determine that the value of goodwill has become impaired, we will record a charge for the amount of impairment during the fiscal quarter in which the determination is made. We operate in one reporting unit.

Restricted cash consists of $301,000 in satisfaction of the letter of credit provisions of the Company’s Bothell, Washington facility lease which has a remaining lease term of approximately 3 years and $55,000 held in an escrow account related to our facility lease in our Zurich, Switzerland facility for which it is management’s expectation to continue to renew this lease beyond the current year. Restricted cash is held in interest-bearing cash accounts and is classified as long term.

We maintain a defined benefit pension plan covering minimum requirements according to Swiss law for our Zurich, Switzerland employees. We recognize the funded status of our defined benefit pension plan on our balance sheets and changes in the funded status are reflected in accumulated other comprehensive income.

Net periodic pension costs are calculated based upon a number of actuarial assumptions, including a discount rate for plan obligations, assumed rate of return on pension plan assets and assumed rate of compensation increases for plan employees. All of these assumptions are based upon management’s judgment, considering all known trends and uncertainties. Actual results that differ from these assumptions would impact the future expense recognition and cash funding requirements of our pension plans.

The financial position and results of operations of our foreign subsidiaries are measured using the local currency as their functional currency. Accordingly, all assets and liabilities for these subsidiaries are translated into U.S. dollars at the current exchange rates as of the respective balance sheet date. Revenue and expense items are translated at the average exchange rates prevailing during the period. Cumulative gains and losses from the translation of these subsidiaries’ financial statements are reported as a separate component of Accumulated other comprehensive income. We record foreign currency transaction gains and losses, realized and unrealized, in other income (expense), net in the consolidated statements of operations. We recorded approximately $33,000 of net transaction gains in 2010 and $35,000 of net transaction gains in 2009.

Our products are generally subject to warranty, which provides for the repair, rework or replacement of products (at our option) that fail to perform within stated specification. We provide for the estimated cost to repair or replace the product at the time of sale. The warranty accrual is estimated based on historical claims and assumes that we will replace products subject to claims.

Research and development expenses are expensed as incurred and consist primarily of mask costs, consulting and outside services, non-capitalized tools and equipment, equipment depreciation and employee compensation, which consists of salaries, benefits and stock-based compensation.

Advertising costs are expensed as incurred. Advertising expenses, which are recorded in selling, general and administrative expenses, were approximately $32,000 and $30,000 for the years ended December 31, 2010 and 2009, respectively.

Stock-based compensation expense is measured at grant date, based on the fair value of the awards ultimately expected to vest and is recognized as an expense, on a straight-line basis, over the requisite service period. We use the Black-Scholes valuation model to measure the fair value of our stock-based awards utilizing various assumptions with respect to expected holding period, risk-free interest rates, stock price volatility and dividend yield.

Forfeitures are required to be estimated at the time of grant and revised if necessary in subsequent periods if actual forfeitures or vesting differ from those estimates. Such revisions could have a material effect on our operating results. The assumptions we use in the valuation model are based on subjective future expectations combined with management judgment. If any of the assumptions used in the Black-Scholes model changes significantly, stock-based compensation for future awards may differ materially compared to the awards granted previously.

From time to time we also issue stock option grants to directors and employees that have a market condition. In such cases stock options will vest only if the average price of our stock is at or exceeds a certain price threshold during a specific, previously defined period of time. To the extent that the market condition is not met, the options do not vest and are cancelled. In these cases, we cannot use the Black-Scholes model; we must use another model. We engage a third party valuation firm to support management’s valuation of these options using Monte Carlo simulation techniques that incorporate assumptions as provided by management for the expected holding period, risk-free interest rate, stock price volatility and dividend yield. Compensation expense is recognized until such time as the market condition is either met or not met. Certain stock options granted on March 17, 2010 were classified as option grants having a market condition.

We also issue stock options which have company specific financial performance criteria. In this case, we make a determination regarding the probability of the performance criteria being achieved and use a Black-Scholes model to value the options incorporating assumptions as provided by management for the expected holding period, risk-free interest rate, stock price volatility and dividend yield. Compensation expense is recognized until such time as the performance criteria is met or not met. Certain stock options granted on October 27, 2010 were classified as option grants having a performance condition.

Comprehensive loss is comprised of two components: net loss and other comprehensive income (loss). Other comprehensive income (loss) refers to revenues, expenses, gains and losses that under U.S. GAAP are recorded as an element of stockholders’ equity, but are excluded from net loss. Statements of comprehensive loss for the years ended December 31, 2010 and 2009 have been included within the consolidated statements of stockholders’ equity. Accumulated other comprehensive income in the accompanying consolidated balance sheets includes foreign currency translation adjustments arising from the consolidation of our foreign subsidiaries. Comprehensive loss is presented net of income tax.

Warrants issued as equity awards are recorded based on the fair value the awards at the grant date. We use the Black-Scholes valuation model to measure the fair value of our equity warrant awards utilizing various assumptions with respect to expected holding period, risk-free interest rates, stock price volatility and dividend yield.

Warrants with certain features, including down-round protection, are recorded as liability awards. These warrants are valued using a Monte Carlo simulation which requires various assumptions with respect to expected holding period, risk-free interest rates, stock price volatility and dividend yield. The warrants are recorded as a liability each reporting period, and the change in the fair value of the liability is recorded as other income or expense until the warrant is exercised or cancelled.

Basic net loss per share is computed using the weighted average number of common shares outstanding. The number of shares used in the computation of diluted net loss per share is the same as those used for the computation of basic net loss per share as the inclusion of dilutive securities would be anti-dilutive because we are is in a loss position for the periods presented.

The provision for income taxes is determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax basis of the Company’s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized.

The calculation of tax liabilities involves dealing with uncertainties in the application of complex global tax regulations. We recognize potential liabilities for anticipated tax audit issues in the U.S. and other tax jurisdictions based on our estimate of whether, and the extent to which, additional taxes will be due. If payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period when we determine the liabilities are no longer necessary. If the estimate of tax liabilities proves to be less than the ultimate assessment, a further charge to expense would result.

additional disclosures that will facilitate financial statement user’s evaluation of the nature of credit risk inherent in financing receivables, how that risk is analyzed in arriving at the allowance for credit losses, and the reason for any changes in the allowance for credit losses. These new standards are required to be adopted for interim and annual reporting periods beginning on or after December 15, 2010. The adoption of these standards will not have a material impact on our consolidated financial statements.

Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, a three-tier fair value hierarchy has been established, which prioritizes the inputs used in measuring fair value as follows:

Level 2: Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and

Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

Our liabilities which are measured at fair value on a recurring basis as of December 31, 2010 and 2009 were determined using the inputs described above ($ in thousands):

The change in the fair value of level 3 liabilities during 2010 is as follows (in thousands):

Property and equipment, net consisted of the following (in thousands, except depreciable life):

Depreciation expense related to property and equipment was $1.6 million and $0.3 million for the years ended December 31, 2010 and 2009, respectively.

Accrued and other current liabilities consisted of the following (in thousands):

The following table sets forth the calculation of basic and diluted net loss per common share (in thousands, except per share amounts):

The following table summarizes securities outstanding which were not included in the calculation of diluted net loss per share because to do so would have been anti-dilutive:

On November 9, 2009, we completed an acquisition of 100% of the voting equity interests of ChipX, Incorporated, (“ChipX”), a privately-held fabless supplier of analog and mixed signal custom Application Specific Integrated Circuits (“ASICs”). The acquisition of ChipX provided us with a rich portfolio of intellectual property and complementary skills that have enabled us to develop new products to expand our offering to the optically connected market. Under the terms of the ChipX Transaction, ChipX stockholders received, in aggregate, 3,540,946 shares of our common stock. The net assets, including identifiable tangible and intangible assets and liabilities, including interest bearing debt of ChipX assumed by us as of the effective time of the ChipX transaction, were recorded at their respective fair values. For accounting and financial reporting purposes, fair value is defined as the price that would be received upon sale of an asset or the amount paid to transfer a liability in an orderly transaction between market participants at the measurement date. Market participants are assumed to be buyers and sellers in the principal (most advantageous) market for the asset or liability. Additionally, fair value measurements for an asset assume the highest and best use of that asset by market participants. Use of different estimates and judgments could yield different results.

The fair values of identifiable intangible assets related to customer relationships, existing technology, trade name and order backlog were primarily determined by using an excess earnings or relief from royalty “income approach,” through which fair value is estimated based on each asset’s discounted projected net cash flows. The fair value of the acquired patents was determined by using a “market approach”, as there were no financial projections specifically related to the patents. Under the income approach, our estimates of market participant net cash flows considered historical and projected pricing, margins and expense levels; the performance of competing products where applicable; relevant industry growth drivers and factors; current and expected trends in technology and product life cycles; the time and investment that will be required to develop products and technologies; the ability to manufacture and commercialize the products; the extent and timing of potential new product introductions by our competitors; and the life of each asset’s underlying patent, if any. The net cash flows are then probability-adjusted where appropriate to consider the uncertainties associated with the underlying assumptions, as well as the risk profile of the net cash flows utilized in the valuation. The probability-adjusted future net cash flows are then discounted to present value utilizing an appropriate discount rate.

The purchase consideration for the merger in 2009 was approximately $12.4 million, which consisted of the fair value of 3.5 million shares of our common stock issued to ChipX’s stockholders, and was determined using a per share price of $3.50, which reflected the closing price of our common stock on November 9, 2009.

The merger was accounted for using the purchase method of accounting. The total purchase price of $12.4 million was allocated to the assets acquired and liabilities assumed as follows (in thousands):

The results of ChipX operations have been included in our consolidated statements of operations since its acquisition date. The revenue of ChipX since the acquisition date through December 31, 2009 that was included in our consolidated statement of operations was $2.1 million. The unaudited pro forma financial information reflected the consolidated results of operations as if the acquisition of ChipX had occurred at the beginning of each period and included the amortization of the resulting identifiable acquired intangible assets for each period presented. The unaudited pro forma financial data is provided for illustrative purposes only and is not necessarily indicative of the consolidated results of operations for future periods or that actually would have been realized had the acquisition occurred at the beginning of each of the periods presented.

Amortization expense of intangible assets included in cost of revenue and selling, general and administrative expenses was approximately $0.4 million and $0.5 million, respectively during the year ended December 31, 2010. Amortization expense of intangible assets included in cost of revenue and selling, general and administrative expenses was approximately $0.9 million and $0.1 million, respectively, during the year ended December 31, 2009. Estimated future amortization expense related to intangible assets as of December 31, 2010 is as follows (in thousands):

We perform a review of the carrying value of our intangible assets, if circumstances warrant. In our review, we compare the gross, undiscounted cash flows expected to be generated by the underlying assets against the carrying value of those assets. To the extent such cash flows do not exceed the carrying value of the underlying asset, we will record an impairment charge. In fiscal 2009, we determined that due to a sharp decline in revenue in the fourth quarter, an impairment analysis of the intangibles relating to existing technology and customer relationships acquired in the acquisition of Helix was warranted. We estimated the fair value of the intangible assets using undiscounted forecasted cash flows; this represents a Level 3 fair value measurement. The analysis indicated that the carrying of the intangible assets should be reduced to zero and, accordingly, we recorded an impairment charge to cost of revenue of $0.4 million.

In connection with the acquisition of ChipX on November 9, 2009, we recorded goodwill of $7.3 million, which was the balance at December 31, 2009. The acquisition of ChipX provided us access to new customers and markets, broadens our portfolio of products, technology and customers, and also will enable us to integrate and leverage its technology into new products and solutions for the optical interconnect market. These factors primarily contributed to a purchase price that resulted in goodwill, which is not deductible for tax purposes. During fiscal 2010, we recorded an additional $0.1 million of goodwill which resulted from an increase in recognized accrued liabilities. The balance of goodwill as of December 31, 2010 was $7.4 million.

On April 23, 2010, we entered into a loan and security agreement with Silicon Valley Bank. Pursuant to the loan and security agreement, we are entitled to borrow from Silicon Valley Bank up to $3.0 million, based on 80% of eligible accounts receivable subject to limits based on our eligible accounts as determined by Silicon Valley Bank (the “Revolving Loan”). Interest on extensions of credit under the Revolving Loan is equal to the prime rate of Silicon Valley Bank, which at December 31, 2010 was 4.0% per annum, plus 1.5% per annum (the “Applicable Rate”). In addition, a monthly collateral handling fee of 0.30% per each gross financed account receivable shall apply (“Collateral Handling Fee”). If we achieve certain quarterly financial performance targets as stated in the loan and security agreement, the Applicable Rate and the Collateral Handling Fee shall be reduced to the prime rate of Silicon Valley Bank plus 1.0% per annum and 0.20%, respectively. The Revolving Loan was used by us to replace our revolving accounts receivable credit line with Bridge Bank. With the initial funding by Silicon Valley Bank of the Revolving Loan, we terminated our loan and security agreement with Bridge Bank, which is discussed below, as having been fully performed by us. The loan and security agreement also contains events of default customary for credit facilities of this type, including, among other things, nonpayment of principal or interest when due. The loan and security agreement will expire on April 23, 2012. The amount outstanding on our line of credit on December 31, 2010 was $3.0 million.

Pursuant to the loan and security agreement, Silicon Valley Bank is making available a term loan in an amount up to $400,000, subject to the satisfaction of terms and conditions of the loan and security agreement, which can be drawn down one time for the purpose of refinancing our outstanding obligations to Agility Capital. The term loan is repayable in eighteen equal monthly installments and interest is fixed at a rate per annum of 9.0%. We used the proceeds of the term loan to pay off our loan and terminate our loan agreement with Agility Capital. The amount outstanding on the term loan on December 31, 2010 was $0.2 million. The weighted average interest rate on our loans outstanding on December 31, 2010 is 5.7%. The average monthly balance on our short-term loans during 2010 was $2.1 million.

The loan and security agreement with Silicon Valley Bank is secured by all of our assets, including all accounts, equipment, inventory, receivables, and intangibles. The loan and security agreement contains certain restrictive covenants that will impose significant operating and financial restrictions on our operations, including, but not limited to:

In connection with the loan and security agreement, we granted Silicon Valley Bank (i) a warrant to purchase 125,000 shares of our common stock at an exercise price equal to $4.00 per share (the “Warrant”), and (ii) a warrant to purchase a second tranche of up to 100,000 shares of our common stock which shall vest 15,000 shares per month incrementally beginning September 1, 2010 (although the last monthly incremental vesting amount shall be 10,000 shares) at an exercise price equal to the closing market price on each date of vesting (the “Second Tranche Warrant”). In the event that either we close an equity investment of at least $4.0 million or we have been EBITDA positive for the preceding three months, then vesting shall cease, and all unvested shares under the Second Tranche Warrant shall lapse. In July 2010, we satisfied the requirements of closing an equity investment of at least $4.0 million and the Second Tranche Warrant expired. The Warrant includes anti-dilution provisions and “piggy-back” registration rights permitting registration in a future public offering by us. The

shares underlying the Warrant were registered on a Registration Statement on Form S-1 that was declared effective by the Securities and Exchange Commission on July 2, 2010. The Warrant may either be (i) converted, on a cashless, net settlement basis, based on the fair market value as determined pursuant to the terms of the Warrant, or (ii) exercised by delivering a duly executed notice of exercise. The Warrant has a term of seven years; the fair value of the Warrant has been determined using a Black-Scholes option pricing model. The full fair value of the warrant has been classified as a non-current asset and as equity on the balance sheet and is being amortized over two years. We have recorded interest expense of $0.1 million during fiscal 2010 related to these warrants. The balance of the asset is $0.2 million as of December 31, 2010.

In November 2009, we entered into a loan and security agreement with Bridge Bank (Credit Agreement) under which we could borrow up to $4.0 million, based on net eligible accounts receivable. Borrowings under the line of credit bore interest at the bank’s prime rate plus 2.50%, provided that in no event would the prime rate be less than 4.0%. Borrowings under the line were collateralized by a security interest in all of our assets. On April 28, 2010, we paid Bridge Bank approximately $1.6 million to fully repay our liabilities covering principal, accrued interest and various fees related to our line of credit, at which time the Credit Agreement was terminated.

On January 29, 2010, we entered into a loan agreement for a secured line of credit facility (“Secured Credit Facility”) with Agility Capital, LLC (“Agility Capital”) to pay for transaction expenses incurred by us in our acquisition of ChipX. The Secured Credit Facility provided that we may borrow one advance of up to $500,000 and had a maturity date of December 1, 2010. Borrowings incurred interest at 14.0% per annum. Beginning March 1, 2010, and on the first day of each month thereafter, $50,000 plus accrued but unpaid interest was to be paid to Agility Capital, and all amounts outstanding on December 1, 2010 were due and payable at that time. In the event of a default, the interest rate will be increased to 5.0% above the rate that would otherwise apply, and in addition, Agility would receive a fee of $5,000, with an additional fee of $5,000 on each thirtieth day thereafter for so long as the event of default continues. Under the terms of the Secured Credit Facility, we paid Agility Capital a $20,000 fee. On April 28, 2010, we paid Agility Capital $0.4 million to fully repay our liabilities covering principal and accrued interest related to our short-term loan, and the Secured Credit Facility was terminated.

In connection with the Credit Agreement and the Secured Credit Facility, we issued warrants to both Bridge Bank and Agility Capital. Certain provisions in the warrant agreements provided for “down round” protection if we raised equity capital at a per share price which was less than the per share price of the warrants. Such down round protection also requires us to classify the value of the warrants as a liability on the issuance date and then record changes in the fair value through the statement of operations for each reporting period until the warrants are either exercised or cancelled. The fair value of the liability is recalculated and adjusted each quarter with the differences being charged to income. The fair value of these warrants was determined using a Monte Carlo simulation which requires the use of significant unobservable inputs to generate the fair value. As a result, these warrants would be classified as level 3 financial instruments. On July 7, 2010 we raised additional equity through an offering of 2,760,000 shares at $1.75 per share, thus triggering the down round protection and adjusting the number of warrants in each warrant agreement.

In connection with the acquisition of Helix, we assumed a pension plan covering minimum requirements according to Swiss law. We have set up the occupational benefits by means of an affiliation to a collective foundation, the Swisscanto Foundation.

Funding Policy: The Company’s practice is to fund the pension plan in an amount at least sufficient to meet the minimum requirements of Swiss law.

The following tables summarize changes in the benefit obligation, the plan assets and the funded status of the pension benefit plan as well as the components of net periodic benefit costs, including key assumptions (in thousands).

The following table summarizes the funding status as of December 31, 2010 (in thousands):

The total net periodic pension cost for the year ending December 31, 2011 is expected to be approximately $43,000. The amount that will be amortized from accumulated other comprehensive income to net periodic benefit cost in 2011 is $0.

As of December 31, 2010, the total accumulated benefit obligation of $534,000 and the projected benefit obligation of $731,000 both exceeded the plan assets of $520,000. As part of other comprehensive income for 2010 we recognized an actuarial gain of $15,000 related to our defined benefit plan in Switzerland.

Weighted average assumptions used to determine benefit obligations as of December 31, 2010 for the plan were a discount rate at 3.00% and rate of compensation increase at 1.50% and an expected return on assets at 3.00%. The GigOptix-Helix Plan is reinsured with the Helvetia Swiss Life Insurance Company via the Swisscanto collective foundation. The expected return on assets as of December 31, 2010 and December 31, 2009 was derived as follows: Swiss pension law requires that the insurance company pay an interest rate of at least 2.0% per annum on old-age savings accounts. In addition to the mandatory rate, we expect 1.0% of surplus sharing from the insurance company.

Weighted average assumptions used to determine costs for the plan as of December 31, 2009 were a discount rate at 3.25%, rate of compensation increase at 1.50% and expected return on assets at 3.00%.

The net periodic benefit cost for the plan included the following components (in thousands):

The benefits are fully insured. There are no retirees and the plan assets are equal to the sum of the old-age savings and of various other accounts within the affiliation contract.

The allocation of the assets of the plan at the measurement dates were 100% in cash and cash equivalents. The Company is required by Swiss law to contribute to retirement funds for the employees of its Swiss subsidiary. Funds are managed by third parties according to statutory guidelines. Cash equivalents may be valued using quoted prices in markets that are not active, resulting in a Level 2 fair value measurement within the hierarchy set forth in the accounting guidance for fair value measurements.

We expect to make contributions to the plan of approximately $30,000 in the year ending December 31, 2011. Actual contributions may differ from expected contributions due to various factors, including performance of plan assets, interest rates and potential legislative changes. We are not able to estimate expected contributions beyond fiscal year 2011.

We do not expect to make further benefit payments through 2018. Actual benefit payments may differ from our expectations.

Under Israeli law, we are required to make severance payments to our retired or dismissed Israeli employees and Israeli employees leaving our employment in certain other circumstances. Our severance pay liability to our Israeli employees is calculated based on the salary of each employee multiplied by the number of years of such employee’s employment and is presented in our balance sheet in long-term liabilities, as if it was payable at each balance sheet date on an undiscounted basis. This liability is partially funded by the purchase of insurance policies in the name of the employees. The surrender value of the insurance policies is presented in long-term assets. Severance pay expense for the year ended December 31, 2010 was $196,000. At December 31, 2010, accrued severance liability and severance assets were $276,000 and $275,000, respectively, resulting in an unfunded portion of the severance plan of $1,000.

We have a 401(k) retirement plan which was adopted by GigOptix, LLC as of January 4, 2008. This plan is intended to be a qualified retirement plan under the Internal Revenue Code. It is a defined contribution as opposed to a defined benefit plan. We have not made matching contributions to employees’ accounts during fiscal 2010 or 2009 and do not plan on making any matching contributions during fiscal 2011.

In December 2008, our stockholders approved an amendment to the Certificate of Incorporation to authorize 50,000,000 shares of common stock of par value $0.001. In addition, we are authorized to issue 1,000,000 shares of undesignated preferred stock of $0.001 par value, for which the Board of Directors is authorized to fix the designation, powers, preferences and rights. As of December 31, 2010 and December 31, 2009, there were no shares of preferred stock issued or outstanding. During the third quarter of fiscal 2010, we raised additional equity by selling an additional 2,760,000 shares to the public at a per share price of $1.75 resulting in gross proceeds of $4.8 million. We had 12,210,264 shares of common stock outstanding as of December 31, 2010.

Under the terms of the Lumera Merger Agreement, upon completion of the merger with Lumera, existing members of GigOptix LLC became the owners of approximately 50% of the outstanding securities, including equity awards and warrants, of us. In December 2008, in connection with maintaining the 50% stock ownership, we issued warrants to purchase 660,473 shares of common stock to one of the members of GigOptix LLC, Stellar Technologies LLC, as follows: 51,278 shares at $17.54 per share; 55,050 shares at $29.27 per share; 128,736 shares at $39.20 per share; 16,391 shares at $70.47 per share; 181,318 shares at $59.92 per share; 22,500 shares

at $24.00 per share; and 205,200 shares at $6.08 per share. Such warrants are immediately exercisable at the date of grant and without any exchange of consideration. In addition, we issued additional warrants to purchase 79,800 shares of common stock to our executives. The warrants are immediately exercisable at the date of grant at an exercise price of $6.08 per share. The warrants expire on July 16, 2013. The estimated fair value of these warrants was approximately $39,000, determined at the date of grant, using the following assumptions: risk free interest rate of 1.55%, volatility of 75%, contractual life of five years, and dividend yield of zero. The fair value of these warrants was expensed within stock-based compensation expense in fiscal year 2008 with corresponding equity classification. As of December 31, 2010, all of these warrants remained outstanding.

In December 2008, we issued 361,866 shares of common stock and 217,120 warrants to purchase common stock to a private investor for consideration of $1.0 million. The warrants are immediately exercisable at the date of grant at an exercise price of $4.87 per share, subject to adjustment upon certain events. The warrants expire on December 4, 2011. The estimated fair value of the warrants was approximately $69,000, determined as the date of grant, using the following assumptions: risk free interest rate of 1.11%, volatility of 75%, contractual life of three years, and dividend yield of zero. We assessed the classification of the warrants in accordance with accounting guidance on derivative financial instruments, and determined that, due to their terms, they qualify for equity classification. As of December 31, 2010, 217,120 of these warrants remained outstanding.

In November 2009, we issued 25,000 warrants to purchase common stock to an investor relations advisor with an exercise price of $1.75 per share. The warrants have a five – year life from the date of issuance. The estimated fair value of these warrants was approximately $48,000, determined at the date of grant, using the following assumptions: risk free interest rate of 1.55%, volatility of 75%, contractual life of five years, and dividend yield of zero. The fair value of these warrants was expensed within sales, general and administrative expense in fiscal year 2009 with corresponding equity classification. As of December 31, 2010, all of these warrants remained outstanding.

In December 2009, we completed a private equity offering (the “Offering”) of units pursuant to securities purchase agreements by and between us and the purchasers listed therein. Pursuant to the Offering, we issued a total of 392,500 shares of common stock, $0.001 par value per share and 392,500 warrants to purchase shares of common stock at an exercise price of $2.50 per share, exercisable commencing six months from the closing date of the Offering and terminating four years from the closing date of the Offering. The total gross proceeds we received from this Offering was $785,000. 162,500 shares and 162,500 warrants purchased by certain investors in this Offering were granted piggyback registration rights and preemptive rights with respect to certain future offerings of equity securities by us. These preemptive rights terminate in the event we conduct a follow-on public offering which occurred on July 1, 2010, and the shares underlying the securities were registered on a Registration Statement on Form S-1 declared effective by the Securities and Exchange Commission on July 2, 2010. In addition, we incurred legal expenses of $19,000 and compensated Sandgrain Securities Inc., as placement agent (the “Placement Agent”), for assisting in the sale of the units by paying them commissions in the amount of $26,000, and issuing them 13,000 shares of common stock and warrants to purchase 13,000 shares of our common stock exercisable at $2.50 per share, exercisable commencing six months from the closing date of the Offering and terminating four years from the closing date of the Offering. The securities issued to the Placement Agent also have piggyback registration rights and preemptive rights with respect to certain future offerings of equity securities by us. These preemptive rights terminate in the event we conduct a follow-on public offering which occurred on July 1, 2010, and the shares underlying the securities were registered on a Registration Statement on Form S-1 declared effective by the Securities and Exchange Commission on July 2, 2010.

In connection with obtaining a line of credit in November 2009 as described in Note 7—Line of Credit, we issued warrants to purchase 59,773 shares of our common stock with an exercise price of $3.35 per share. In addition, as partial consideration for the waiver of certain events of default that arose under the line of credit, we

issued a warrant dated April 7, 2010 to purchase 20,000 shares of our common stock with an exercise price of $3.65 per share. These warrants have a seven-year life from the date of issuance, and, as of December 31, 2010, all of these warrants remain outstanding. The fair value of the warrants issued was determined using a Monte Carlo simulation which requires the use of significant unobservable inputs to generate the fair value. As a result, these warrants would be classified as level 3 financial instruments. See Note 7—Line of Credit.

In connection with obtaining a line of credit that was terminated in 2009, we issued 4,125 warrants to purchase common stock with an exercise price of $0.73 per share. The warrants have a ten-year life from the date of issuance. As of December 31, 2010, these warrants were outstanding. The fair value of the warrants issued was insignificant.

In connection with the merger with Lumera, we issued warrants to purchase approximately 488,818 shares of common stock with exercise price range from $6.08 to $70.40. The estimated fair value of the warrants was determined as of December 9, 2008, the date the merger was completed, using the following assumptions: risk free interest rate of 1.61%, volatility of 75%, contractual life of five years, and dividend yield of zero. The fair value of the warrants was $173,000 and was included in the Lumera purchase price consideration. As of December 31, 2010, all of these warrants remained outstanding.

On January 29, 2010, in connection with a secured line of credit facility (Secured Credit Facility) with Agility Capital, LLC (Agility Capital) to pay for transaction expenses incurred by us in our acquisition of ChipX, we issued a warrant for the purchase of 71,429 shares of our common stock. The warrant may either be (i) converted, on a cashless, net settlement basis, based on the fair market value as determined pursuant to the terms of the warrant, or (ii) exercised at a price per share equal to the lower of $2.10 or the price paid in the next offering or issuance of the Company’s common stock, if such offering occurs by April 29, 2010. Events of default under our loan agreement with Agility Capital arose in March 2010 that Agility Capital agreed to waive. As partial consideration for the waiver, we issued an additional warrant dated April 5, 2010 for the purchase of 25,000 shares of our common stock with an exercise price of $2.00 per share. These warrants have a term of seven years, and as of December 31, 2010, all of these warrants remain outstanding. The fair value of the warrants issued was determined using a Monte Carlo simulation which requires the use of significant unobservable inputs to generate the fair value. As a result, these warrants would be classified as level 3 financial instruments. See Note 7—Line of Credit.

On April 23, 2010, in connection with a loan and security agreement with Silicon Valley Bank, we granted Silicon Valley Bank (i) a warrant to purchase 125,000 shares of our common stock at an exercise price equal to $4.00 per share (the “Warrant”), and (ii) a warrant to purchase a second tranche of up to 100,000 shares of our common stock which shall vest 15,000 shares per month incrementally beginning September 1, 2010 (although the last monthly incremental vesting amount shall be 10,000 shares) at an exercise price equal to the closing market price on each date of vesting (the “Second Tranche Warrant”). In the event that either we close an equity investment of at least $4.0 million or we have been EBITDA positive for the preceding three months, then vesting shall cease, and all unvested shares under the Second Tranche Warrant shall lapse. In July 2010, we satisfied the requirements of closing an equity investment of at least $4.0 million and the Second Tranche Warrant expired. The Warrant includes anti-dilution provisions and “piggy-back” registration rights permitting registration in a future public offering by us. The shares underlying the Warrant were registered on a Registration Statement on Form S-1 declared effective by the Securities and Exchange Commission on July 2, 2010. The Warrant may either be (i) converted, on a cashless, net settlement basis, based on the fair market value as determined pursuant to the terms of the Warrant, or (ii) exercised by delivering a duly executed notice of exercise. The Warrant has a term of seven years; the fair value of the Warrant has been determined using a Black-Scholes option pricing model. The Warrant has a fair value of $357,000 and is being amortized over a two year period. We recorded expense of $123,000 during the year ended December 31, 2010.

As of December 31, 2010, we had a total of 2,167,703 warrants to purchase common stock outstanding under all warrant arrangements. Many of the warrants have anti-dilution provisions which adjust the number of warrants available to the holder, such as, but not limited to, stock dividends, stock splits and certain reclassifications, exchanges, combinations or substitutions. These provisions are specific to each warrant agreement.

As of December 31, 2010, there were 6,024,201 options and 4,125 warrants outstanding under all stock option plans. As of December 31, 2009, there were 3,085,160 options and 4,125 warrants outstanding under all stock option plans.

In August 2007, GigOptix LLC adopted the GigOptix LLC Equity Incentive Plan, or the “2007 Plan”. The 2007 Plan provided for grants of options to purchase membership units, membership awards and restricted membership units to employees, officers and non-employee directors, and upon the completion of the merger with Lumera were converted into grants of up to 632,500 shares of stock. Vesting periods are determined by our Board of Directors and generally provide for stock options to vest over a four-year period and expire ten years from date of grant. Vesting for certain shares of restricted stock are contingent upon both service and performance criteria. The 2007 Plan was terminated upon the completion of merger with Lumera on December 9, 2008 and the remaining 864 stock options not granted under the 2007 Plan were cancelled. No shares of our common stock remain available for issuance of new grants under the 2007 Plan other than for satisfying exercises of stock options granted under this plan prior to its termination. As of December 31, 2010, no shares of common stock have been reserved for issuance for new grants under the 2007 Plan and options to purchase a total of 453,432 shares of common stock and 4,125 warrants to purchase common stock were outstanding.

In December 2008, we adopted the 2008 Equity Incentive Plan, or the “2008 Plan”, for directors, employees, consultants and advisors to us or our affiliates. Under the 2008 Plan, 2,500,000 shares of common stock were reserved for issuance upon the completion of merger with Lumera on December 9, 2008. On January 1 of each year, starting in 2009, the aggregate number of shares reserved for issuance under the 2008 Plan increase automatically by the lesser of (i) 5% of the number of shares of common stock outstanding as of our immediately preceding fiscal year, or (ii) a number of shares determined by the Board of Directors. The maximum number of common stock to be granted is up to 21,000,000 shares. Forfeited options or awards generally become available for future awards. As of December 31, 2010, 9,223,166 shares have been authorized for future issuance, and 3,628,992 shares are available for future grants.

Awards under the 2008 Plan may be granted through June 30, 2018. Under the 2008 Plan, the exercise price of (i) an award is at least 100% of the stock’s fair market value on the date of grant, and (ii) an ISO granted to a 10% stockholder is at least 110% of the stock’s fair market value on the date of grant. Vesting periods for awards are determined by the CEO and generally provide for stock options to vest over a four-year period and have a maximum life of ten years from the date of grant. As of December 31, 2010, there were 5,418,446 options to purchase common stock outstanding and 3,628,992 options were available for issuance under the 2008 Plan.

In December 2008, in connection with the merger with Lumera, we assumed the existing Lumera 2000 Equity Incentive Plan, and the Lumera 2004 Stock Option Plan (the “Lumera Plan”). All unvested options

granted under the Lumera Plan were assumed by us as part of the merger. All contractual terms of the assumed options remain the same, except for the converted number of shares and exercise price based on merger conversion ratio of 0.125. As of December 31, 2010, no additional options can be granted under the Lumera Plan and options to purchase a total of 152,323 shares of common stock were outstanding. including employee stock options, restricted stock units and employee stock purchase rights based on their estimated fair values. The fair value of equity-based awards is amortized on a straight-line basis over the requisite service period of the award which is generally the vesting period.

We grant stock-based compensation awards under our 2008 Equity Incentive Plan. We have outstanding grants under our prior plans, but no further grants can be made under those prior plans.

The following table summarizes our employee-related stock-based compensation expense for fiscal years 2010 and 2009:

Management estimates expected forfeitures and it records compensation expense only for those equity awards expected to vest. When estimating forfeitures, we consider voluntary termination behavior as well as an analysis of actual option forfeitures.

As of December 31, 2010, the total compensation cost related to unvested stock options under our equity compensation plan, but not yet recognized, was approximately $3.6 million. This cost will be amortized on a straight-line basis over a weighted-average period of approximately 3.2 years.

We estimate the fair value of stock options granted using a Black-Scholes option-pricing model. This model requires the input of highly subjective assumptions, including the options’ expected life and the price volatility of our underlying stock options. Actual volatility, expected lives, interest rates and forfeitures may be different than our assumptions, which would result in an actual value of the options being different than estimated. This fair value of stock option grants is amortized on a straight-line basis over the requisite service period of the awards, which is generally the vesting period.

From time to time we also issue stock option grants to directors and employees that have a market condition. In such cases stock options will vest only if the average price of our stock is at or exceeds a certain price threshold during a specific, previously defined period of time. To the extent that the market condition is not met, the options do not vest and are cancelled. In these cases, we cannot use the Black-Scholes model; we must use a binomial model. We engage a third party valuation firm to support management’s valuation of these options using Monte Carlo simulation techniques that incorporate assumptions as provided by management for the expected holding period, risk-free interest rate, stock price volatility and dividend yield. Compensation expense is recognized until such time as the market condition is either met or not met. Certain stock options granted on March 17, 2010 were classified as option grants having a market condition.

The fair value of our stock options granted to employees was estimated using the following weighted-average assumptions:

Expected Term—The Company’s expected term used in the Black-Scholes valuation method represents the period that our stock options are expected to be outstanding and is derived from the historical expected terms of “guideline” companies selected based on similar industry and product focus.

Expected Volatility—Our expected volatility used in the Black-Scholes valuation method is derived from a combination of historical and implied volatility of “guideline” companies selected based on similar industry and product focus. Forfeitures are estimated at the time of grant and are revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

Expected Dividend—We have never paid dividends and currently does not intend to do so, and accordingly, the dividend yield percentage is zero for all periods.

Risk-Free Interest Rate—We base the risk-free interest rate used in the Black-Scholes valuation method on the implied yield currently available on U.S. Treasury constant maturities issued with a term equivalent to the expected term of the option.

The following table summarizes information about options granted and outstanding under our equity incentive plans as of December 31, 2010:

The aggregate intrinsic value of options outstanding and exercisable based on the fair value of the underlying stock options as of December 31, 2010 was approximately $6.0 million and $2.5 million, respectively. The aggregate intrinsic value reflects the difference between the exercise price of the underlying stock options and our closing stock price of $2.75 as of December 31, 2010. The weighted average remaining contractual term of options exercisable as of December 31, 2010 was approximately 7.43 years.

The following is a summary of shares of restricted stock activity for the Company’s equity incentive plans:

The fair value of our shares of restricted stock is calculated based upon the fair market value of our underlying stock at the date of grant. As of December 31, 2010 and December 31, 2009, there was no unrecognized compensation cost related to unvested shares of restricted stock. As of December 31, 2010, we had no shares of unvested restricted stock outstanding.

The components of loss before provision for income taxes are as follows (in thousands):

Components of (provision for) benefit from income taxes are as follows (in thousands):

Benefit from (provision for) income taxes differs from the amount computed by applying the statutory United States federal income tax rate to loss before taxes as follows:

We provided a full valuation allowance on deferred tax assets in excess of deferred tax liabilities. Because of our limited operating history and cumulative losses, management believes it is more likely than not that the remaining deferred tax asset will not be realized. All U.S. deferred tax assets have a full valuation allowance at December 31, 2010.

We have approximately $34 million of federal net operating losses carryforwards at December 31, 2010. The net operating losses begin to expire in 2027. We have approximately $10 million of state net operating loss carryforwards at December 31, 2010. The net operating losses begin to expire in 2018. Utilization of a portion of the net operating losses and credit carryforwards are subject to an annual limitation due to the ownership change provision of the Internal Revenue Code of 1986, as amended, and similar state provisions. The annual limitation may result in the expiration of net operating losses and credits before utilization. We also have approximately $16 million of net operating loss carryforwards in Israel related to our acquisition of ChipX. These losses in that jurisdiction can be carried forward indefinitely.

Our unrecognized tax benefits at December 31, 2010 relate to various domestic and foreign jurisdictions. As of December 31, 2010, we had total gross unrecognized tax benefits of $1.6 million, which if recognized would not affect the effective tax rate. As of December 31, 2010, the amount of long-term income taxes payable for unrecognized tax benefits, including accrued interest, was $38,000. We do not anticipate any significant changes to our unrecognized tax benefits within the next 12 months.

A reconciliation of the December 31, 2009 through December 31, 2010 amount of unrecognized tax benefits is as follows: (in thousands)

We have adopted the accounting policy that interest recognized in accordance with Paragraph 15 of FIN 48 and penalty recognized in accordance with Paragraph 16 of FIN 48 are classified as part of our income taxes and would not affect the FIN rate amount. In 2010, we recorded $0 of such interest and penalty expense and as of December 31, 2010, the balance of such accrued balance and penalty was $0.

We file U.S. federal, U.S. state and foreign tax returns. Our major tax jurisdictions are the U.S., California, Switzerland, Israel and the UK. Our fiscal years through 2010 remain subject to examination by the tax authorities for U.S. federal, state, and foreign tax purposes.

We have determined that we operate as a single operating and reportable segment. The following tables reflect the results of our reportable segment consistent with the management system used by our chief operating decision maker.

We determine geographic location of our revenue based upon the destination of shipment of our products.

During fiscal year 2010, the United States and Japan accounted for 50% and 12% of revenue, respectively. During fiscal year 2009, the United States, Italy and Hong Kong accounted for 49%, 22% and 11% of revenue, respectively. No other countries accounted for more than 10% of our consolidated revenue during the periods presented.

Long-lived assets, comprising property and equipment, are reported based on the location of the assets at end of each fiscal year.

We lease our domestic and foreign sales offices under non-cancelable operating leases. These leases contain various expiration dates and renewal options. In January 2009, the Company renewed its lease for its office facility located at Palo Alto, California. The new lease term will expire in December 2013. The Company also leases certain software licenses under operating leases. Total facilities rent expense for 2010 and 2009 was $0.6 million and $0.7 million, respectively.

Aggregate non-cancelable future minimum lease payments under capital and operating leases are as follows (in thousands):

The gross and net book value of property and equipment purchased under capital lease was as follows (in thousands):

The amortization of computer software acquired under capital lease is included in depreciation expense.

Our income tax calculations are based on application of the respective U.S. Federal, state or foreign tax law. Our tax filings, however, are subject to audit by the respective tax authorities. Accordingly, we recognize tax liabilities based upon our estimate of whether, and the extent to which, additional taxes will be due.

From time to time, we may become involved in legal proceedings, claims and litigation arising in the ordinary course of business. When we believe a loss is probable and can be reasonably estimated, we accrue the estimated loss in our consolidated financial statements. Where the outcome of these matters is not determinable, we do not make a provision in our financial statements until the loss, if any, is probable and can be reasonable estimated or the outcome becomes known. We believe that there are currently no claims or legal actions that would, in management’s judgment based on information currently available, have a material adverse effect on GigOptix’ results of operations, financial condition or cash flows.

In or about November 2008, an entity named DBSI Inc., which at the time was the beneficial owner of membership units in a predecessor of ours, and which in December 2008 converted into 1,715,161 shares of our

common stock (all of which are now held by the DBSI Liquidating Trust), filed for bankruptcy in the United States Bankruptcy Court for the District of Delaware (Case No. 08-12687 (PJW)). We understand that an affiliate of the DBSI Liquidating Trust, the DBSI Estate Litigation Trust, is currently evaluating claims that it may assert against a number of entities, including GigOptix and/or its predecessors and affiliates. In November 2010, we entered tolling agreements with the trustee of the DBSI Estate Litigation Trust to allow the parties to continue discussions in an attempt to avoid litigation. On March 3, 2011, we agreed to extend the expiration of the tolling agreement to April 21, 2011. Our management has engaged in discussions with the trustee regarding whether the DBSI Estate Litigation Trust has any claims against us, and intends to vigorously defend any claims made against us.

Our products typically carry a standard warranty period of one year. The table below summarizes the movement in the warranty accrual, which is included as a component of accrued and other current liabilities, for the years ended December 31, 2010 and 2009 (in thousands):

During the three months ended December 31, 2010, we reduced by $40,000 our previous estimate of Israel severance expense.

During the three months ended April 4, 2010, we decided to close our R&D design center in Haifa, Israel which was acquired as part of the merger with ChipX in 2009. We took a restructuring charge of $388,000 to

account for employee severance of $156,000, future facility rent expense of $61,000 for the remainder of the lease term through the end of fiscal 2010, a write-down of fixed assets of $121,000, and accounting and legal expenses of $50,000. We paid out $354,000 during 2010 in connection with the Israel restructuring.

In December 2009, the Company adopted a plan to reduce the size of its facilities in Bothell, Washington. The Company reduced the amount of square footage it occupies from approximately 32,000 square feet to approximately 12,000 square feet and took a restructuring charge of $424,000 to reflect the proportionate share of remaining lease expense it will incur for the unoccupied space of the facility and costs associated with improvements needed to segregate the facility. The existing lease on the facility expires on March 31, 2014. Although the Company has made available for sub-lease approximately 20,000 square feet, it did not receive any sublease income associated with this space prior to a negotiated reduction in space, which occurred on February 1, 2011. The company paid out $396,000 related to unoccupied space in Bothell during 2010.

In October 2009, in anticipation of its acquisition by us, ChipX incurred severance costs of $0.4 million in connection with a reduction in its work force. We recognized this expense in its consolidated statement of operations after the acquisition date as a restructuring expense. All amounts were paid prior to December 31, 2009.

As a result of the acquisition of ChipX on November 9, 2009, National Instruments Corporation, a former stockholder of ChipX, currently holds 1,066,265 shares of our common stock. Since the date of the acquisition, we generated revenue of $1.6 million and $231,000 from sales to National Instruments Corporation during the years ended December 31, 2010 and 2009, respectively.

On February 4, 2011, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Endwave Corporation (“Endwave”) pursuant to which a wholly-owned subsidiary of ours will, subject to the satisfaction or waiver of the conditions therein, merge with and into Endwave, the result of which the separate corporate existence of the wholly-owned subsidiary shall cease and Endwave will be the successor or surviving corporation of the merger (the “Merger”) and our wholly-owned subsidiary. Under the terms of the merger agreement, all outstanding shares of Endwave common stock, including those issuable upon settlement of outstanding restricted stock units, and outstanding in-the-money Endwave stock options, will be converted into shares of GigOptix common stock such that immediately after the merger, such shares represent approximately 42.5% of all outstanding GigOptix common stock. Based on the number of shares of Endwave and GigOptix common stock outstanding as of January 31, 2011, approximately 9.1 million shares of GigOptix common stock will be issued to holders of Endwave common stock, registered stock units and stock options. On February 3, 2011, the Board approved the establishment of a $500,000 retention bonus pool to be payable to our employees who are still so employed 15 days after the closing of the Merger. The Board has delegated to the Compensation Committee to approve the amounts that each officer and employee of ours is eligible to receive as part of such retention bonus pool, and such determination, including who will be an eligible participant in such retention bonus pool, has not yet been made, although it is anticipated that the named executive officers will be eligible participants. As of February 25, 2011, we have incurred accounting and banking fees of approximately $290,000 related to the Endwave transaction.

On February 25, 2011, Agility Capital net share exercised both of the warrants issued to it. See Note 7—Line of Credit and Note 9—Stockholders’ Equity.

We have audited the accompanying balance sheets of Endwave Corporation and its subsidiaries (the “Company”) as of December 31, 2010 and 2009, and the related statements of operations, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2010. Our audits also included the financial statement schedule listed in Item 15(a)(2). These consolidated financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor have we been engaged to perform, an audit of the Company’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Endwave Corporation and its subsidiaries as of December 31, 2010 and 2009, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2010 in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the related financial statement schedule, when considered in relation to the consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

The accompanying notes are an integral part of these consolidated financial statements.

Endwave Corporation (“Endwave” or the “Company”) designs, manufactures and markets radio frequency (“RF”), products that enable the transmission, reception and processing of high frequency RF signals. The Company’s products consist of two key product lines, semiconductor devices and integrated transceiver modules:

On February 4, 2011, Endwave entered into an Agreement and Plan of Merger with GigOptix, Inc. (“GigOptix”), and Aerie Acquisition Corporation, a wholly-owned subsidiary of GigOptix (“Merger Subsidiary”), pursuant to which Merger Subsidiary will, subject to the satisfaction or waiver of the conditions therein, merge with and into Endwave, the separate corporate existence of Merger Subsidiary shall cease and Endwave will be the surviving corporation of the merger and a wholly-owned subsidiary of GigOptix. See additional discussion at Note 15, Subsequent Events.

On April 30, 2009, the Company sold its Defense and Security RF module business to Microsemi Corporation (“Microsemi”). The Company’s financial statements have been presented to reflect the Defense and Security RF module business as a discontinued operation for all periods presented. See additional discussion at Note 11, Discontinued Operations.

The accompanying consolidated financial statements of Endwave include the financial results of its Defense and Security RF module business as a discontinued operation for all periods presented and have been prepared in conformity with accounting principles generally accepted in the United States of America. All significant intercompany accounts and transactions have been eliminated.

Certain prior year financial statement amounts have been reclassified to conform to the current year’s presentation. These reclassifications had no impact on previously reported total assets, stockholders’ equity or total net income (loss).

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

The Company’s primary customers are telecom original equipment manufacturers (“OEM”) and other systems integrators that integrate the Company’s products into their systems. The Company recognizes product revenues at the time title passes, which is generally upon product shipment and when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the Company’s price to the buyer is fixed or determinable, and collectibility is reasonably assured. After title passes, there are no customer acceptance requirements or other remaining obligations and customers do not have a right of return. Revenues under development contracts are generally recorded on a percentage of completion basis, using project hours as the basis to measure progress toward completing the contract and recognizing revenues. The costs incurred under these development agreements are expensed as incurred and included in research and development expenses.

The warranty periods for the Company’s products are between 12 and 30 months from date of shipment. The Company provides for estimated warranty expense at the time of shipment. While the Company engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of component suppliers, its warranty obligation is affected by product failure rates, material usage, and service delivery costs incurred in correcting a product failure. Should actual product failure rates, material usage, or service delivery costs differ from the estimates, revisions to the estimated warranty accrual and related costs may be required.

Changes in the Company’s accrued warranty during the years ended December 31, 2010 and 2009 are as follows:

The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. The Company provides an allowance for specific customer accounts where collection is doubtful and also provides an allowance for other accounts based on historical collection and write-off experience. If the financial condition of customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required.

The Company invests its excess cash primarily in highly liquid investment grade investments including: United States treasury notes, United States government agency notes, corporate notes, commercial paper and money market funds. The Company’s cash, cash equivalents and short-term investments are primarily held at three United States banks. The Company’s deposits are generally in excess of federally insured amounts.

The Company considers all highly liquid investments with maturities of 90 days or less from the date of purchase to be cash equivalents. Management has classified the Company’s short-term investments as available-for-sale securities in the accompanying consolidated financial statements. Available-for-sale securities are carried at fair value based on quoted market prices, with unrealized gains and losses, net of tax, included in accumulated other comprehensive income (loss) in stockholders’ equity. Interest income is recorded using an effective interest rate, with the associated premium or discount amortized to interest income. Realized gains and losses and declines in the value of securities determined to be other-than-temporary are included in interest and other income. The cost of securities sold is based on the specific identification method.

Inventories are stated at the lower of standard cost (determined on a first-in, first-out basis) or market (net realizable value). Standard costs approximate average actual costs. The Company makes inventory provisions for estimated excess and obsolete inventory based on management’s assessment of future demand and market conditions. If actual future demand or market conditions are less favorable than those projected by management, additional inventory write-downs may be required. During 2010 and 2009, the Company recorded $1.8 million and $878,000, respectively, of inventory write-offs associated with excess and obsolete material related to a rapid drop in sales of a legacy product for a major customer’s radio platform.

Property and equipment are stated at cost. Depreciation is computed on a straight-line basis over the estimated useful lives of the assets, ranging from three to seven years. Leasehold improvements and assets acquired under capital lease are amortized using the straight-line method based upon the shorter of the estimated useful lives or the lease term of the respective assets. Repairs and maintenance costs are charged to expense as incurred.

During the fourth quarter of 2008, the Company determined that indicators of potential impairment were present based on the fair value of the Company’s common stock relative to its book value, revised estimates for future revenues and the continued worsening of the global economy. As a result, the Company assessed the carrying value of acquired goodwill and intangible assets with an indefinite life for impairment. Based on the fair market value of the business and the Company’s discounted future cash flow and revenue projections, the Company recorded non-cash impairment charges of $3.0 million for goodwill and $1.1 million for intangible assets with an indefinite life. These impairment charges are included in discontinued operations.

The Company reviews long-lived assets for impairment, whenever certain events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable. Such events or circumstances include, but are not limited to, a prolonged industry downturn, or a significant reduction in projected future cash flows.

For long-lived assets used in operations, the Company records impairment losses when events and circumstances indicate that these assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amounts of those assets. If less, the impairment losses are based on the excess of the carrying amounts over their respective fair values. Their fair values would then become the new cost basis. Fair value is determined by discounted future cash flows, appraisals, or other methods. For assets to be disposed of other than by sale, impairment losses are measured as the excess of their carrying amount over the salvage value, if any, at the time the assets cease to be used.

During the fourth quarter of 2008, the Company reviewed its long-lived assets for indicators of impairment. Based on reduced estimates of future revenues and future negative cash flow, the Company identified potential indicators of impairment. As a result, the Company compared the fair value of its long-lived assets to their carrying value. Based on the Company’s discounted future cash flow and revenue projections, the Company recorded non-cash impairment charges of $2.1 million for intangible assets with a defined useful life. The impairment charges are included in discontinued operations and represent the excess of the carrying value of these assets over their fair value.

These impairment charges are not expected to result in any future cash expenditures.

Income taxes have been provided using the asset and liability method. Deferred tax assets and liabilities are determined based on the differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse.

The Company has adopted the accounting standard which provides guidance on the provisions of accounting for uncertainty in income taxes. It provides guidance on accounting for uncertainty in income taxes recognized in the consolidated financial statements and prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. It also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. In accordance with the Company’s accounting policy, the Company recognizes accrued interest and penalties related to unrecognized tax benefits as a component of income tax expense.

The Company recognizes stock-based compensation for stock-based awards exchanged for employee services. Stock-based compensation cost is measured at the grant date, based on the fair value of the award, and is recognized as expense over the requisite service period. All of the Company’s stock compensation is accounted for as an equity instrument.

The Company has elected the alternative transition method for calculating the tax effects of stock-based compensation. The alternative transition method provides a simplified method to establish the beginning balance of the additional paid-in capital pool, or APIC Pool, related to the tax effects of employee stock-based compensation, and to determine the subsequent impact on the APIC Pool and consolidated statements of cash flows of the tax effects of employee stock-based compensation awards that are outstanding.

The Company uses the “with and without” approach to determine the order in which its tax attributes are utilized. The “with and without” approach results in the recognition of the windfall stock option tax benefits after all other tax attributes have been considered in the annual tax accrual computation. The Company will only recognize a benefit from stock-based compensation in paid-in capital if an incremental tax benefit is realized after all other tax attributes currently available to it have been utilized. In addition, the Company has elected to account for the indirect benefits of stock-based compensation on items such as the alternative minimum tax, the research tax credit or the domestic manufacturing deduction through the consolidated statements of operations rather than through paid-in capital.

The Company accounts for stock options issued to nonemployees based on the fair value of the awards also determined using the Black-Scholes option-pricing model. The fair value of stock options granted to nonemployees is remeasured as the stock options vest, and the resulting change in value, if any, is recognized in the Company’s consolidated statement of operations during the period the related services are rendered.

Research and development expenses are charged to operating expenses as incurred and consist primarily of salaries and related expenses for research and development personnel, outside professional services, prototype materials, supplies and labor, depreciation for related equipment, allocated facilities costs and expenses related to stock-based compensation.

The Company is potentially subject to significant concentrations of credit risk including cash equivalents, short-term investment, trade receivables and inventories.

The Company sells its products primarily to telecom OEMs and other systems integrators. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. The Company maintains reserves for potential credit losses and excess and obsolete inventory. Concentrations of credit risk with respect to trade accounts receivable and inventories are due to the low number of entities comprising the Company’s customer base.

For the year ended December 31, 2010, revenues from three customers each accounted for greater than 10% of total revenues and combined they accounted for 93% of the Company’s total revenues, the largest of which was Nokia Siemens Networks which accounted for 52% of the Company’s total revenues. For the year ended December 31, 2009, revenues from two customers each accounted for greater than 10% of total revenues and combined they accounted for 88% of the Company’s total revenues, the largest of which was Nokia Siemens Networks which accounted for 70% of the Company’s total revenues. For the year ended December 31, 2008, revenues from Nokia Siemens Networks accounted for 83% of total revenues and no other customer accounted for more than 10% of our total revenues. In addition, the Company has purchased significant inventory balances to support these customers.

In 2010, 2009, and 2008, 76%, 97% and 97%, respectively, of the Company’s total revenues were derived from sales invoiced and shipped to customers outside the United States.

As of December 31, 2010, two customers accounted for 58% and 28%, respectively, of the Company’s accounts receivable. As of December 31, 2009, two customers accounted for 47% and 39%, respectively, of the Company’s accounts receivable.

The Company designs custom semiconductor devices. However, the Company does not own or operate a semiconductor fabrication facility (a “foundry”) and depends upon a limited number of third parties to produce these components. The Company’s use of various third-party foundries gives it the flexibility to use the process technology that is best suited for each application and eliminates the need for the Company to invest in and maintain its own foundry. The loss of the Company’s relationship with or access to the foundries it currently uses, and any resulting delay or reduction in the supply of semiconductors to the Company, would severely impact the Company’s ability to fulfill customer orders and could damage its relationships with its customers.

The Company also may not be successful in forming alternative supply arrangements that provide a sufficient supply of gallium arsenide devices. Because there are limited numbers of third-party foundries that use the particular process technologies the Company selects for its products and have sufficient capacity to meet its needs, using alternative or additional third-party foundries would require an extensive qualification process that could prevent or delay product shipments and their associated revenues.

Because the Company does not own or control any of these third-party semiconductor suppliers, any change in the corporate structure or ownership of the corporations that own these foundries could have a negative effect on future relationships and the ability to negotiate favorable supply agreements.

The Company outsources the assembly and testing of most of its products to a Thailand facility of HANA Microelectronics Co., Ltd., (“HANA”) a contract manufacturer. The Company plans to continue this arrangement as a key element of its operating strategy. If HANA does not provide the Company with high quality products and services in a timely manner, or terminates its relationship with the Company, the Company may be unable to obtain a satisfactory replacement to fulfill customer orders on a timely basis. In the event of an interruption of supply from HANA, sales of the Company’s products could be delayed or lost and the Company’s reputation could be harmed. The Company’s manufacturing agreement with HANA currently expires in October 2011 but will renew automatically for successive one-year periods unless either party notifies the other of its desire to terminate the agreement at least one year prior to the expiration of the term. In addition, either party may terminate the agreement without cause upon 365 days prior written notice to the other party, and either party may terminate the agreement if the non-terminating party is in material breach and does not cure the breach within 30 days after notice of the breach is given by the terminating party. There can be no guarantee that HANA will not seek to terminate its agreement with the Company.

The Company utilizes a number of customized components that need to be qualified by our customers. This means that components in our products cannot be easily changed without the risks and delays associated with requalification. Accordingly, while a number of the components used in the Company’s products are made by multiple suppliers, the Company may effectively have single source suppliers for some of these components. In addition, the Company currently purchases a number of components from single source suppliers. Any delay or interruption in the supply of these or other components could impair the Company’s ability to manufacture and deliver products, harm the Company’s reputation and cause a reduction in revenues.

The amounts reported as cash and cash equivalents, accounts receivable, accounts payable and accrued warranty, compensation and other liabilities approximate fair value due to their short-term maturities. The fair value for the Company’s investments in marketable debt securities is estimated based on quoted market prices. Based upon borrowing rates currently available to the Company for capital leases with similar terms, the carrying value of its capital lease obligations approximates fair value.

The following estimated fair value amounts have been determined using available market information. However, considerable judgment is required in interpreting market data to develop the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts that the Company could realize in a current market exchange.

At December 31, 2010, the Company had $16.4 million of short-term investments with maturities of less than one year and no long-term investments.

At December 31, 2010, the Company had unrealized losses of $3,000 related to $8.3 million of investments in United States government agencies securities. These securities were in an unrealized loss position for a period of less than one year.

The investments mature through 2011 and the Company believes that it has the ability and intent to hold these investments until the maturity date. Realized gains were $57,000 for the year ended December 31, 2008. Realized gains and losses were insignificant for the years ended December 31, 2010 and 2009.

The Company reviews its investment portfolio to identify and evaluate investments that have indications of possible impairment. Factors considered in determining whether a loss is temporary include the length of time and extent to which fair value has been less than the cost basis, credit quality and the Company’s intent and ability not to sell the investment for a period of time sufficient to allow for any anticipated recovery in market value. If the Company believes the carrying value of an investment is in excess of its fair value, and this difference is other-than-temporary, it is the Company’s policy to write down the investment to reduce its carrying value to fair value.

The following table summarizes the Company’s financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2010 (in thousands):

The following table summarizes the Company’s financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2009 (in thousands):

The Company’s financial assets and liabilities are valued using market prices on both active markets (Level 1) and less active markets (Level 2). Level 1 instrument valuations are obtained from real-time quotes for transactions in active exchange markets involving identical assets. Level 2 instrument valuations are obtained from readily-available pricing sources for comparable instruments. As of December 31, 2010, the Company did not have any assets or liabilities without observable market values that would require a high level of judgment to determine fair value (Level 3).

For the years ended December 31, 2010 and 2009, the Company did not have any significant transfers of investments between Level 1 and Level 2.

The U.S. dollar is the functional currency for the Company’s foreign operations. In consolidation, monetary assets and liabilities denominated in non-U.S. currencies, such as cash and payables, have been remeasured to the U.S. dollar using the current exchange rate. Non-monetary assets and liabilities and capital accounts denominated in non-U.S. currencies have been remeasured to the U.S. dollar using the historical exchange rate. Expense items relating to monetary assets denominated in non-U.S. currencies have been remeasured to the U.S. dollar using the average exchange rate for the period. Gains and losses from intercompany transactions and balances for which settlement is not planned or anticipated in the foreseeable future are accumulated as a separate component of stockholders’ equity. All other gains and losses resulting from foreign currency translation and transactions denominated in currencies other than the U.S. dollar are included in operations and have been immaterial for all periods presented.

Comprehensive income (loss) generally represents all changes in stockholders’ equity except those resulting from investments or contributions by stockholders. The Company’s unrealized gains and losses on its available-for-sale securities and gains and losses resulting from foreign exchange translations represent the only components of comprehensive income (loss) excluded from the reported net income (loss) and are displayed in the statements of stockholders’ equity.

The components of accumulated other comprehensive income (loss) were as follows (in thousands):

Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period. Diluted net income (loss) per share is computed by dividing the net income (loss) for the period by the weighted average number of shares of common stock and potential common stock equivalents outstanding during the period, if dilutive. Potential common stock equivalents include convertible preferred stock, warrants to purchase convertible preferred stock, stock options to purchase common stock, unvested restricted stock units and shares to be purchased in connection with the Company’s employee stock purchase plan.

The following outstanding shares of common stock equivalents were excluded from the computation of diluted net income (loss) per share for the periods presented because including them would have been anitdilutive:

In 2010, 2009 and 2008, basic and diluted net loss per share is the same due to the Company’s loss from continuing operations.

The Company expenses all advertising costs as incurred and the amounts were not material for any of the periods presented.

In January 2010, the Financial Accounting Standards Board (“FASB”) issued new standards for fair value measurement and disclosures. These new standards require disclosures for significant transfers in and out of Level 1 and Level 2 fair value measurements and the reasons for the transfers and activity. For Level 3 fair value measurements, purchases, sales, issuances and settlements must be reported on a gross basis. Further, additional disclosures are required by class of assets or liabilities, as well as inputs used to measure fair value and valuation techniques. These standards were required to be adopted in the first quarter of 2010. The Company adopted these standards which did not have a material impact on the Company’s consolidated financial statements.

In February 2010, the FASB issued new standards which amend the subsequent event disclosure requirements for public company filers. An entity that is an SEC filer is not required to disclose the date through which subsequent events have been evaluated. These standards were effective upon issuance and did not have a material impact on the Company’s consolidated financial statements.

In July 2010, the FASB issued new standards which amend the receivable disclosure requirements, including the credit quality of financing receivables and the allowance for credit losses. These standards require additional disclosures that will facilitate financial statement user’s evaluation of the nature of credit risk inherent in financing receivables, how that risk is analyzed in arriving at the allowance for credit losses, and the reason for any changes in the allowance for credit losses. These new standards are required to be adopted for interim and annual reporting periods beginning on or after December 15, 2010. The Company adopted these standards which did not have a material impact on the Company’s consolidated financial statements.

During 2010 and 2009, the Company recorded $1.8 million and $878,000, respectively, of inventory write-offs associated with excess and obsolete material related to a rapid drop in sales of a legacy product for a major customer’s radio platform.

During the third quarter of 2008, the Company was issued a note receivable by one of its customers, Allgon Microwave Corporation AB (“Allgon”), which previously failed to meet the terms of its account payable to the Company. The note was in the principal amount of $545,000, with payments of $25,000 due on a weekly basis. The note was to be paid in full by the end of the first quarter of 2009.

During the third and fourth quarters of 2008, Allgon made the first five payments under the note. However, during the fourth quarter of 2008, Allgon went in default on the note and filed for bankruptcy protection. At the time of default, the note receivable balance was $420,000. Based on Allgon’s bankruptcy liquidation and the related estimates of payments to Allgon’s creditors, the Company reserved 100% or $420,000 of the remaining balance of the note receivable.

Subsequent to Allgon’s default on the note receivable, the Company filed a complaint alleging that Allgon’s parent company, Advantech Advanced Microwave Technologies Inc. of Montreal, Canada (“Advantech”), had breached its contractual obligations with the Company and owes the Company $994,500, including the note receivable, purchased inventory and authorized and accepted purchase orders resulting in shippable finished goods. See additional discussion at Note 10, Commitments and Contingencies.

During the first quarter of 2009, the Company occupied a lease in Salem, New Hampshire. For this property, the Company capitalized $99,000 of leasehold improvements that will be depreciated over the remaining life of the lease ending in 2013.

During the third quarter of 2006, the Company moved its corporate headquarters to San Jose, California. For this property, the Company capitalized $496,000 of leasehold improvements that will be depreciated over the remaining life of the lease ending in 2011.

During the second quarter of 2004, the Company finalized the sale of its land and buildings located in Diamond Springs, California. The Company received $4.3 million for the land and buildings, net of related closing costs and legal fees. The net book value of the property on the date of sale was $3.5 million. At the time of the closing, the Company entered into a five-year operating lease with the new owner for one of the buildings. As a result of the sale-leaseback transaction, the Company recognized a gain of $770,000 on a straight-line basis over the term of the lease, which expired in June 2009. Deferred gain recognized on the sale-leaseback was approximately $76,000 and $154,000 for the years ended December 31, 2009 and 2008, respectively, and is included in interest and other income, net in the consolidated statements of operations. There was no such deferred gain in 2010.

At December 31, 2010, the Company had $36,000 of capital leased equipment with an accumulated depreciation of $34,000, which is included in machinery and equipment. At December 31, 2009, the Company had $36,000 of capital leased equipment with an accumulated depreciation of $25,000, which is included in machinery and equipment.

The Company operates in a single business segment. Although the Company sells to customers in various geographic regions throughout the world, the end users may be located elsewhere. The Company’s total revenues by billing location for the years ended December 31 were as follows (in thousands):

At December 31, 2010, 45% and 55% of the Company’s net book value of its long-lived assets were located in the United States of America and Thailand, respectively. At December 31, 2009, 70% and 30% of the Company’s net book value of its long-lived assets were located in the United States of America and Thailand, respectively.

On August 11, 2009, the Company filed a Tender Offer Statement on Schedule TO with the Securities and Exchange Commission. The tender offer related to an offer by the Company to certain optionholders to exchange some or all of their outstanding stock option grants to purchase shares of the Company’s common stock granted under the Company’s 2007 Equity Incentive Plan with an exercise price per share greater than $5.00 for new option grants at an exchange ratio of three old options for one new option. The exchange offer was made to employees and directors of the Company who, as of the date the exchange offer commenced, were actively employed and held 1,570,938 eligible options. The exchange offer expired on September 9, 2009. 1,559,113 options participated in the exchange offer and were exchanged for 519,624 new options. The new options primarily have a two-year vesting period. All new options have an exercise price of $2.53 per share, the closing price of the Company’s common stock on September 10, 2009.

The exchange of original options for new options was treated as a modification of the original options. As such, the Company will continue to incur compensation cost for the incremental difference between the fair value of the new options and the fair value of the original options immediately before modification, reflecting the current facts and circumstances on the modification date, over the expected term of the new options. Since the incremental difference between the fair value of the new options and the fair value of the original options immediately before modification was immaterial, the $661,000 value of the options is primarily due to the carry-forward value of the old options into the new options.

On January 4, 2008, the Company filed a Tender Offer Statement on Schedule TO with the Securities and Exchange Commission. The tender offer related to an offer by the Company to certain optionholders to exchange some or all of their outstanding stock option grants under the Company’s 2007 Equity Incentive Plan with an exercise price per share greater than or equal to $21.47 for new option grants. The exchange offer was made to employees and directors of the Company who, as of the date the exchange offer commenced, were actively employed by or otherwise providing services to the Company and held eligible option grants. The exchange offer expired on February 6, 2008. A total of 331,950 stock options were eligible to participate in the exchange offer and a total of 327,921 options were exchanged. The exercise price of the new option grants was $6.59, the closing price of the Company’s common stock on February 7, 2008.

The exchange of original options for new options was treated as a modification of the original options, As such, the Company will continue to incur compensation cost for the incremental difference between the fair value of the new options and the fair value of the original options immediately before modification, reflecting the current facts and circumstances on the modification date, over the expected term of the new options. The incremental value related to the Exchange Offer was $607,000 prior to forfeitures.

Stock-based compensation cost is measured at the grant date, based on the fair value of the award, and is recognized as expense over the requisite service period. All of the Company’s stock compensation is accounted for as an equity instrument.

The effect of recording stock-based compensation for the years ended December 31 was as follows (in thousands, except per share data):

For the compensation cost in connection with the Company’s employee stock purchase plan for the year ended December 31, 2010, the Company recognized a benefit of $130,000 due to actual contributions being less than expected contributions for the offering period due to forfeitures.

During the year ended December 31, 2010, the Company granted options to purchase 387,900 shares of its common stock with an estimated total grant date fair value of $564,000. Of this amount, the Company estimated that the stock-based compensation for the awards not expected to vest was $94,000.

During the year ended December 31, 2010, the Company granted restricted stock units to purchase 218,000 shares of its common stock with an estimated total grant date fair value of $583,000. Of this amount, the Company estimated that the stock-based compensation for the awards not expected to vest was $65,000. The Company did not grant restricted stock units during the years ended December 31, 2009 and 2008.

During the year ended December 31, 2009, the Company granted options to purchase 1,082,924 shares of common stock, including 519,624 options granted as part of the 2009 exchange offer noted above. The 519,624 options granted as part of the 2009 exchange offer had an estimated total grant-date fair value of $661,000 or $1.27 per option. The remaining 563,300 options had an estimated total grant-date fair value of $596,000 or $1.06 per option. The total estimated grant-date fair value of all 1,082,924 options granted was $1.3 million. Of this amount, the Company estimated that the stock-based compensation expense of the awards not expected to vest was a total of $274,000.

During the three months ended June 30, 2009, the Company fully accelerated the vesting of 165,600 options in connection with the closing of the Microsemi transaction and certain restructuring activities. The Company recorded additional stock-based compensation expense of $66,000 relating to the incremental value of the fully vested modified awards.

During the three months ended December 31, 2009, the Company fully accelerated the vesting of 223,352 options in connection with certain restructuring activities. The Company recorded additional stock-based compensation expense of $164,000 relating to the incremental value of the fully vested modified awards.

During the year ended December 31, 2008, the Company granted options to purchase 1,025,821 shares of common stock, including 327,921 options granted as part of the 2008 exchange offer noted above. The 327,921 options granted as part of the 2008 exchange offer had an estimated total grant-date fair value of $607,000 or

$1.85 per option. The remaining 697,900 options had an estimated total grant-date fair value of $2.2 million or $3.20 per option. The total estimated grant-date fair value of all 1,025,821 options granted was $2.8 million. Of this amount, the Company estimated that the stock-based compensation expense of the awards not expected to vest was a total of $810,000.

As of December 31, 2010, the unrecorded stock-based compensation balance related to all stock options was $392,000, net of estimated forfeitures, and will be recognized over an estimated weighted-average employee service period of 1.3 years. As of December 31, 2010, the unrecorded stock-based compensation balance related to all restricted stock units was $290,000, net of estimated forfeitures, and will be recognized over an estimated weighted-average employee service period of 1.1 years. As of December 31, 2010, the unrecorded deferred stock-based compensation balance related to the stock purchase plan was $97,000 and will be recognized over an estimated weighted average employee service period of 0.5 years.

The fair value of each option grant is estimated on the date of grant using the Black-Scholes option valuation model and the graded-vesting method with the following weighted-average assumptions:

The fair value of shares under the employee stock purchase plan is estimated using the Black-Scholes valuation model and the graded-vesting method with the following weighted average assumptions:

The dividend yield of zero is based on the fact that the Company has never paid cash dividends and has no present intention to pay cash dividends. Expected volatility is based on the combination of historical volatility of the Company’s common stock over the period commensurate with the expected life of the options and other factors. The risk-free interest rates are taken from the Daily Federal Yield Curve Rates as of the grant dates as published by the Federal Reserve and represent the yields on actively traded Treasury securities for terms equal to the expected term of the options. The expected term calculation is based on the Company’s observed historical option exercise behavior and post-vesting forfeitures of options by employees.

The weighted average grant date fair value for options granted during 2010, 2009, and 2008 was $1.45, $1.16, and $2.77, per share, respectively. The total intrinsic value of options exercised during the years ended December 31, 2010, 2009, 2008 was $55,000, $145,000, $7,000, respectively.

The weighted average grant date fair value of purchase rights granted under the employee stock purchase plan during the year was $0.72, $0.59, $1.17, for 2010, 2009, and 2008, respectively.

The Company had 5,000,000 shares of convertible preferred stock authorized as of December 31, 2010 and 2009.

In April 2006, the Company entered into a purchase agreement with Oak Investment Partners XI, Limited Partnership (“Oak”). Pursuant to the purchase agreement, Oak purchased 300,000 shares of the Company’s Series B preferred stock, par value $0.001 per share, for $150 per preferred share, or a total of $45.0 million. The preferred shares were convertible initially into 3,000,000 shares of common stock, for an effective purchase price of $15 per common share equivalent. The Company also issued Oak a warrant granting Oak the right to purchase an additional 90,000 shares of Series B preferred stock at an exercise price of $150 per share. The warrant expired on April 24, 2009. The Company received net proceeds of $43.1 million from the sale of the Series B preferred stock and the warrant after the payment of legal fees and other expenses, including commissions.

On January 21, 2010, the Company repurchased all 300,000 outstanding shares of its preferred stock held by Oak for $120 per share, or a total of $36.0 million in cash. The total cost of the repurchase was $36.2 million, which included fees and expenses. The 300,000 outstanding shares represented 3,000,000 shares of Endwave common stock on an as-converted basis. Such shares had entitled Oak to a liquidation preference equal to its original investment of $45.0 million before any proceeds from a liquidation or sale of the Company would have been paid to the holders of Endwave’s common stock. In connection with the share repurchase, Eric Stonestrom, Oak’s designee to Endwave’s board of directors, resigned from the board of directors.

Since the Company repurchased the preferred stock for official retirement, the excess of the stated value, $43.1 million, over the effective repurchase price of $36.2 million was credited to additional paid-in capital.

At December 31, 2010, the Company had reserved 4,574,072 shares of common stock for issuance in connection with its stock option plans, and 446,473 shares in connection with its employee stock purchase plan.

In October 2000, the Company established the Endwave Corporation Employee Stock Purchase Plan (“Purchase Plan”). All employees who work a minimum of 20 hours per week and are customarily employed by the Company (or an affiliate thereof) for at least five months per calendar year are eligible to participate. Employees may purchase shares of common stock through payroll deductions of up to 15% of their earnings with a limit of 3,000 shares per purchase period under the Purchase Plan. The price paid for the Company’s common stock purchased under the Purchase Plan is equal to 85% of the lower of the fair market value of the Company’s common stock on the date of commencement of participation by an employee in an offering under the Purchase Plan or the date of purchase.

During 2010, there were 64,390 shares issued under the Purchase Plan at a weighted average price of $2.01 per share. During 2009, there were 141,235 shares issued under the Purchase Plan at a weighted average price of $2.25 per share. During 2008, there were 207,222 shares issued under the Purchase Plan at a weighted average price of $3.82 per share.

The Company’s 2000 Stock Option Plan (the “2000 Plan”) was adopted in March 2000, amended in July 2000, and in July 2007 was succeeded by the 2007 Equity Incentive Plan. All shares reserved for issuance under the 2000 Plan were carried over into the 2007 Plan.

The Company’s 2007 Equity Incentive Plan (the “2007 Plan”) was adopted in July 2007 as the successor and continuation of the 2000 Plan and provides for the issuance of options to purchase common stock to directors, employees, and consultants. The 2007 Plan provides for annual reserve increases to the number of authorized shares beginning January 1, 2008 through January 1, 2012. Under the 2007 Plan, incentive stock options are granted under the plan at exercise prices not less than fair value and non-statutory stock options are granted at an exercise price not less than 85% of the fair value on the date of grant, as determined by the closing sales price of the Company’s common stock. Options granted under the 2007 Plan generally have a ten-year term. Options vest and become exercisable as specified in each individual’s option agreement, generally over a two to four year period. Subject to approval by the Company’s board of directors, options may be exercised early; however, in such event the unvested shares are subject to a repurchase option by the Company upon termination of the individual’s employment or services. As of December 31, 2010, the 2007 Plan provides for the issuance of up to 1,432,987 shares of common stock to directors, employees and consultants upon the exercise of options outstanding.

The Company’s 2000 Non-Employee Directors’ Stock Option Plan (“Director Plan”) was adopted in October 2000 and terminated in October 2010, such that no further options could be granted thereunder. No options remain outstanding in the 2000 Director Plan.

The Company granted restricted stock units to non-employee directors to purchase 30,000 shares of the Company’s common stock under the 2007 Plan for the year ended December 31, 2010.

The Company granted options to non-employee directors to purchase 117,143 and 60,000 shares of the Company’s common stock under the 2007 Plan for the years ended December 31, 2009 and 2008, respectively.

The Company’s equity incentive program is a broad-based, long-term retention program designed to align stockholder and employee interests. Upon exercise of stock options, the Company issues shares from the shares reserved under the Company’s stock option plans.

The following table summarizes stock option activity under the equity incentive plans for the indicated periods:

The following table summarizes information concerning outstanding and exercisable options:

The following table summarizes the restricted stock unit activity for the indicated periods:

At December 31, 2010, the Company had 193,765 restricted stock units vested and expected to vest with a weighted average remaining contractual term of 0.67 years and an aggregate intrinsic value of $442,000.

At December 31, 2010, the Company had 4,574,072 options available for grant under its stock option plans. For the year ended December 31, 2010, 62 options expired.

At December 31, 2009 and 2008, options to purchase 439,125 and 1,585,385 shares of common stock were exercisable at weighted average exercise prices of $2.24 and $9.77 per share, respectively.

During the first quarter of 2009, the Company undertook certain restructuring activities to reduce expenses. The components of the restructuring charge included severance, benefits, payroll taxes and other costs associated with employee terminations. The net charge for these restructuring activities was $1.2 million and all cash payments have been made. Of this amount, approximately $182,000 has been included in the discontinued operations line item on the consolidated statements of operations.

During the second quarter of 2009, the Company undertook certain additional restructuring activities to reduce expenses. The components of the restructuring charge included severance, benefits, payroll taxes and other costs associated with employee terminations. The net charge for these restructuring activities was $243,000 and all cash payments have been made. Of this amount, approximately $39,000 has been included in the discontinued operations line item on the consolidated statements of operations.

During the fourth quarter of 2009, the Company undertook certain additional restructuring activities, including the departure of a senior executive, to reduce expenses. The components of the restructuring charge included severance, benefits, payroll taxes and other costs associated with employee terminations. The net charge for these restructuring activities was $1.2 million. The remaining restructuring liability of $665,000 at December 31, 2010 is expected to be substantially paid by the end of the third quarter of 2012.

During the third quarter of 2010, the Company undertook certain additional restructuring activities to reduce expenses. The components of the restructuring charge included severance, benefits, payroll taxes and other costs associated with an employee termination. The net charge for these restructuring activities was $63,000 and all cash payments have been made.

Changes in all of the Company’s restructuring liabilities discussed are summarized as follows (in thousands):

At December 31, 2010, $431,000 and $234,000 of accrued restructuring charges are included in current liabilities and long-term liabilities, respectively, on the consolidated balance sheet. At December 31, 2009, $570,000 and $638,000 of accrued restructuring charges are included in current liabilities and long-term liabilities, respectively, on the consolidated balance sheet. The restructuring liability related to a senior executive was recorded at its fair value based on an assumed interest rate of 5.0%, which represents the current market rate of interest at which the Company could borrow, due to the long-term nature of the liability.

The Company will recognize interest expense associated with amortizing the $77,000 discount on this liability over the 30 month term of the restructuring payout. During the year ended December 31, 2010, the Company recognized interest expense of $46,000. The amount related to 2009 was insignificant.

The Company’s restructuring estimates will be reviewed and revised quarterly and may result in an increase or decrease to restructuring charges. During the first quarter of 2010, the Company recorded a $14,000 positive adjustment as a result of lower benefit charges in connection with the first quarter 2009 restructuring plan than were originally anticipated.

The Company leases its office, manufacturing and design facilities in San Jose, California, Chiang Mai, Thailand, Salem, New Hampshire and Folsom, California under non-cancelable lease agreements, which expire in various periods through November 2013. Rent expense under the operating leases was approximately $675,000, $692,000 and $616,000 for the years ended December 31, 2010, 2009 and 2008 respectively.

Future annual minimum lease payments under non-cancelable operating leases with initial terms of one year or more as of December 31, 2010 are as follows (in thousands):

Future annual minimum lease payments under non-cancelable capital leases as of December 31, 2010 are as follows (in thousands):

The amounts due under capital leases are included in other current and long-term liabilities on the consolidated balance sheet.

The Company has purchase obligations to certain suppliers. In some cases the products the Company purchases are unique and have provisions against cancellation of the order. At December 31, 2010, the Company had approximately $1.4 million of purchase obligations which are due within the following 12 months. This amount does not include contractual obligations recorded on the consolidated balance sheets as liabilities.

On October 31, 2008, the Company filed a complaint with the Canadian Superior Court in Montreal, Quebec alleging that Advantech, the parent company of Allgon Microwave Corporation AB, had breached its contractual obligations with Endwave and owes the Company $994,500 in a note receivable, purchased inventory and accepted purchase orders. The Company cannot predict the outcome of these proceedings. An adverse decision in these proceedings could harm the Company’s consolidated financial position and results of operations. Other than the complaint against Advantech, the Company is not currently a party to any material litigation.

On April 30, 2009, the Company entered into an Asset Purchase Agreement (the “Purchase Agreement”) with Microsemi, pursuant to which Microsemi purchased the Company’s Defense and Security RF module business including all of the outstanding capital stock of Endwave Defense Systems, Incorporated (“EDSI”). As consideration, Microsemi assumed certain liabilities associated exclusively with the Defense and Security RF module business, including the Company’s building lease in Folsom, California, and paid $28.0 million in cash. The Purchase Agreement contains representations and warranties as to the Defense and Security RF module business that survive for two years following the closing. In connection with the transaction, the Company entered into an indemnification agreement pursuant to which the Company agreed to indemnify Microsemi for environmental, product liability and intellectual property infringement claims related to the Company’s operation of the Defense and Security RF module business prior to the closing date, as well as for any other excluded liability, and Microsemi agreed to indemnify the Company for any claims related to the operation of the Defense and Security RF module business following the closing date and for any other assumed liability, subject in some cases to a customary deductible and limitation on maximum damages.

Concurrently with the closing of the acquisition, the Company entered into a transition services agreement and an employee transition services agreement with Microsemi pursuant to which the Company agreed to provide to Microsemi for a limited period of time certain transitional services, including accounting, human resources, information technology and product supply services.

The Company classified the results of the Defense and Security RF module business as a discontinued operation in the Company’s consolidated statements of operations for all periods presented. The results of operations for the Defense and Security RF module business classified as discontinued operations are as follows (in thousands):

The $19.6 million gain on sale of discontinued operations, net of tax, included the following: $28.0 million of cash received from Microsemi offset by $647,000 of deal fees, $9.1 million of assets transferred to Microsemi and $1.3 million of liabilities assumed by Microsemi.

Consolidated loss before income tax expense (benefit) includes non-U.S. loss of approximately $904,000, $804,000 and $853,000 for the years ended December 31, 2010, 2009 and 2008, respectively. The Company recorded a current tax benefit of $0, $105,000 and $66,000 for year ended December 31, 2010, 2009 and 2008, respectively.

As of December 31, 2010, the Company had a federal net operating loss carryforward of approximately $205.6 million. The Company also had federal research and development tax credit carryforwards of approximately $2.2 million. These net operating loss and credit carryforwards are currently expiring and will continue to do so through 2030, if not utilized.

As of December 31, 2010, the Company had a state net operating loss carryforward of approximately $82.2 million. The net operating losses will begin expiring in 2012, if not utilized. The Company also has state research and development tax credit carryforwards and miscellaneous credit carryforwards of approximately $2.4 million. The credits will carryforward indefinitely, if not utilized.

Utilization of the net operating losses and credits may be subject to a substantial annual limitation due to the ownership change provisions of the Internal Revenue Code and similar state provisions. The annual limitation may result in the expiration of net operating losses and credits before utilization.

Deferred tax assets and liabilities reflect the net tax effects of net operating loss and credit carryforwards and temporary differences between the carrying amounts of assets for financial reporting and the amount used for income tax purposes. Significant components of the Company’s net deferred tax assets and liabilities for federal and state income taxes are as follows at December 31 (in thousands):

Realization of deferred tax assets is dependent upon future earnings, if any, the timing and amount of which are uncertain. Accordingly, the net deferred tax assets have been offset by a valuation allowance. The valuation allowance increased by $1.3 million during 2010, decreased by $7.9 million during 2009 and increased by $3.9 million during 2008, respectively.

The Company is tracking the portion of its deferred tax assets attributable to stock option benefits in a separate memo account. Therefore, these amounts are no longer included in our gross or net deferred tax assets. The benefit of these stock options will only be recorded to equity when they reduce cash taxes payable. As of December 31, 2010, the Company had federal and state net operating loss carryforwards being accounted for in this memo account of $22.4 million.

The Company’s income tax expense (benefit) differed from the amount computed by applying the statutory U.S. federal income tax rate to the loss before income taxes as follows (in thousands):

The aggregate changes in the balance of gross unrecognized tax benefits during the year were as follows (in thousands):

If the ending balance of $2.5 million of unrecognized tax benefits at December 31, 2010 were recognized, approximately $124,000 would affect the effective income tax rate. In accordance with the Company’s accounting policy, it recognizes interest and/or penalties related to income tax matters in income tax expense. As of December 31, 2010, the Company had no accrued interest and/or penalties. The Company does not anticipate a significant change to its unrecognized tax benefits over the next twelve months. The unrecognized tax benefits may change during the next year for items that arise in the ordinary course of business.

The Company files U.S. federal and state income tax returns. Tax years 1994 through 2010 remain subject to examination by the appropriate government agencies due to tax loss carryovers from those years.

Substantially all U.S. regular employees of the Company meeting certain service requirements are eligible to participate in the Company’s 401(k) employee retirement plan. Employee contributions are limited to the maximum amount allowed under the Internal Revenue Code. The Company may match contributions based upon a percentage of employee contributions up to a maximum of 4% of employee compensation. Company contributions under these plans were $0, $71,000 and $281,000 for 2010, 2009 and 2008, respectively. During 2009, the Company suspended its match of contributions.

On February 4, 2011, Endwave entered into an Agreement and Plan of Merger with GigOptix and Aerie Acquisition Corporation, a wholly-owned subsidiary of GigOptix, pursuant to which Merger Subsidiary will, subject to the satisfaction or waiver of the conditions therein, merge with and into Endwave, the separate corporate existence of Merger Subsidiary shall cease and Endwave will be the surviving corporation of the merger and a wholly-owned subsidiary of GigOptix. This agreement is referred to as the Merger Agreement and the proposed merger contemplated by the Merger Agreement as the Merger.

Upon the consummation of the Merger, (i) the outstanding shares of Endwave common stock will be converted into the right to receive an aggregate number of shares of GigOptix common stock equal to the product of (.425/.575) and the number of shares of GigOptix common stock outstanding immediately prior to consummation of the Merger, less 42.5% of the shares described in clause (ii) of this sentence and (ii) in-the-money options to acquire Endwave common stock outstanding immediately prior to the consummation of the Merger will be converted into that number of shares of GigOptix common stock determined by dividing the spread value of such options at closing by the closing price of GigOptix’ common stock on the trading day prior to closing, such that following the Merger, the pre-Merger holders of common stock and restricted stock units will own that number of shares equal to 42.5% of the outstanding stock of the combined company, less 42.5% of the shares issued in respect of Endwave stock options.

The Merger Agreement includes customary representations, warranties and covenants of Endwave and GigOptix. Endwave has agreed to conduct its operations and the operations of its subsidiaries according to its ordinary and usual course of business consistent with past practice until the effective time of the Merger. The

Merger Agreement contains customary “no-solicitation” covenants pursuant to which neither Endwave nor GigOptix is permitted to solicit any alternative acquisition proposals, provide any information to any person in connection with any alternative acquisition proposal, participate in any discussions or negotiations relating to any alternative acquisition proposal, approve, endorse or recommend any alternative acquisition proposal, or enter into any agreement relating to any alternative acquisition proposal. The “no-solicitation” provision is subject to certain exceptions that permit the Board of Directors of each of Endwave and GigOptix, as the case may be, to comply with their respective fiduciary duties, which, under certain circumstances, would enable Endwave or GigOptix, as the case may be, to provide information to, and engage in discussions or negotiations with, third parties with respect to alternative acquisition proposals.

The Merger Agreement contains certain termination rights for both Endwave and GigOptix and further provides that, upon termination of the Merger Agreement under certain circumstances, Endwave may be obligated to pay GigOptix a termination fee of $1,000,000 plus certain reasonable documented expenses of GigOptix.

The Merger which is subject to regulatory approvals as well as approvals by the stockholders of Endwave is not expected to close before the second quarter of 2011.

During the first quarter of 2011, the Company will undertake certain restructuring activities to reduce expenses. The Company announced its plan to terminate the employment of a total of 14 employees and is closing its facilities in Salem, New Hampshire and Folsom, California in order to reduce the Company’s cost structure. These terminations will affect all areas of the Company’s operations. The components of the expected restructuring charge include facilities, severance, benefits, payroll taxes, acceleration of certain stock awards for the affected personnel, and other costs associated with these activities. The Company is expected to incur cash charges of approximately $700,000 and the payments are expected to be substantially completed by the end of the second quarter of 2011.

This Agreement and Plan of Merger (this “Agreement”) is made and entered into as of February 4, 2011 (the “Agreement Date”) by and among GigOptix, Inc., a Delaware corporation (“GigOptix”), Aerie Acquisition Corporation, a Delaware corporation and wholly-owned subsidiary of GigOptix (“Merger Sub”), and Endwave Corporation, a Delaware corporation (“Endwave”), with respect to the following facts:

Section 2.01 Conversion of Stock. Pursuant to the Merger, and without any action on the part of the holders of any outstanding shares of capital stock or securities of Endwave or Merger Sub:

(b) As of the Effective Time, each holder of record of Converting Endwave Common Stock shall cease to have any rights with respect thereto, except the right to receive (i) a certificate (or, at the Holder’s request, direct registration) representing the number of whole shares of GigOptix Common Stock into which such shares have been converted, and (ii) cash in lieu of fractional shares of GigOptix Common Stock in accordance with Section 2.01(f), without interest.

(c) As of the Effective Time, each share of Endwave Common Stock held of record immediately prior to the Effective Time by Endwave, Merger Sub, GigOptix or any Subsidiary of GigOptix shall be cancelled and extinguished without any conversion thereof.

(d) As of the Effective Time, each share of Common Stock, $0.001 par value, of Merger Sub (the “Merger Sub Common Stock”) issued and outstanding immediately prior to the Effective Time shall be cancelled,

extinguished and automatically converted into one validly issued, fully paid and nonassessable share of Common Stock, $0.001 par value, of the Surviving Corporation. Each certificate evidencing ownership of a number of shares of Merger Sub Common Stock shall be deemed to evidence ownership of the same number of shares of Common Stock, $0.001, of the Surviving Corporation.

(e) In the event of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into capital stock), reorganization, reclassification, combination, recapitalization or other like change with respect to Endwave Common Stock or GigOptix Common Stock occurring after the Agreement Date and prior to the Effective Time, all references in this Agreement to specified numbers of shares of any class or series affected thereby, and all calculations provided for that are based upon numbers of shares of any class or series (or trading prices therefor) affected thereby, shall be equitably adjusted to the extent necessary to provide the parties the same economic effect as contemplated by this Agreement prior to such stock split, reverse stock split, stock dividend, reorganization, reclassification, combination, recapitalization or other like change.

(f) No fraction of a share of GigOptix Common Stock will be issued by virtue of the Merger. Instead, each Holder who would otherwise be entitled to a fraction of a share of GigOptix Common Stock (after aggregating all fractional shares of GigOptix Common Stock to be received by such holder) shall receive from GigOptix an amount of cash (rounded down to the nearest whole cent) equal to the product of (i) such fraction, multiplied by (ii) the GigOptix Closing Value. For the purposes of this Agreement, “GigOptix Closing Value” shall mean the closing price per share of GigOptix Common Stock as reported on the OTC Bulletin Board on the trading day immediately preceding the Effective Time.

Section 2.02 Endwave Options and Restricted Stock Units. As of the Effective Time, by virtue of the Merger and without any action on the part of the holders thereof, each Endwave Option that is outstanding and unexercised as of immediately prior to the Effective Time shall terminate and cease to represent a right to acquire Endwave Common Stock, and the holder thereof shall be entitled to receive therefor that number of shares of GigOptix Common Stock equal to (a) the product of (i) the difference between the closing price of Endwave’s Common Stock as reported on Nasdaq on the trading day immediately prior to the Effective Time and the per-share exercise price of such Endwave Option and (ii) the number of whole shares of Endwave Common Stock (with any fractional shares being settled in cash as provided in Section 2.01(f)) that were issuable upon exercise of Endwave Option, whether or not vested, divided by (b) the GigOptix Closing Value. The aggregate number of shares of GigOptix Common Stock to be issued pursuant to the prior sentence to the holders of the terminated Endwave Options shall be referred to herein as the “Endwave Option Shares”. As of the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof, each Endwave Restricted Unit that is outstanding as of immediately prior to the Effective Time shall terminate and cease to represent a right to acquire Endwave Common Stock, and the holder thereof shall be entitled to receive that number of shares of GigOptix Common Stock equal to (a) the product of (i) the number of shares of Endwave Common Stock issuable upon settlement of such Endwave Restricted Unit, whether or not vested, and (ii) the Conversion Ratio. All such shares of GigOptix Common Stock issuable pursuant to this Section 2.02 (i) shall be subject to applicable withholding for federal, state and other taxes, such withholding to be satisfied by reducing the number of shares of GigOptix Common Stock (and cash in respect of fractional shares) otherwise issuable and (ii) shall not serve as an offset to or otherwise reduce the severance benefits to which a holder of Endwave Options or Endwave Restricted Units may otherwise be entitled. Endwave shall provide GigOptix all information (other than share price information) needed to effectuate such withholding at least three business days prior to the Effective Time. Endwave shall take all action necessary to terminate the Endwave Option Plans as of immediately prior to the Effective Time.

Section 2.03 Endwave Stock Purchase Plan. By virtue of GigOptix not assuming outstanding rights of or substituting similar rights for participants under the Endwave Stock Purchase Plan, accumulated payroll deductions under the Endwave Stock Purchase Plan shall be used to purchase Endwave Common Stock immediately prior to the Effective Time. Endwave shall take all action necessary to terminate the Endwave Stock Purchase Plan as of the Effective Time.

(b) At or prior to the Effective Time, GigOptix shall supply or cause to be supplied to or for the account of the Exchange Agent in trust for the benefit of the Holders of Endwave Common Stock, for exchange pursuant to this Section 2.04 (i) certificates (or, at the Holder’s request, direct registration) evidencing the shares of GigOptix Common Stock issuable pursuant to Section 2.01 to be exchanged for outstanding shares of Endwave Common Stock, and (ii) cash in an aggregate amount sufficient to make the payments in lieu of fractional shares provided for in Section 2.01(f).

(c) Promptly (and in no event more than five business days) after the Effective Time, GigOptix shall mail or shall cause to be mailed to each Holder a letter of transmittal in customary form (which shall specify that delivery shall be effected, and risk of loss and title to the Endwave Certificates shall pass, only upon proper delivery of the Endwave Certificates to the Exchange Agent) and instructions for surrender of the Endwave Certificates. Upon surrender to the Exchange Agent of an Endwave Certificate (if any), together with such letter of transmittal duly executed, the Holder shall be entitled to receive in exchange therefor (no later than five business days after the Exchange Agent’s receipt of the duly executed letter of transmittal and, if applicable, Endwave Certificate): (i) certificates evidencing that number of shares of GigOptix Common Stock issuable to such Holder in accordance with this Article II; (ii) any dividends or other distributions that such Holder has the right to receive pursuant to Section 2.04(d); and (iii) cash in respect of fractional shares as provided in Section 2.01(f), and such Endwave Certificate so surrendered shall forthwith be cancelled. No certificate representing shares of GigOptix Common Stock will be issued to a Person who is not the registered owner of a surrendered Endwave Certificate unless (i) the Endwave Certificate so surrendered has been properly endorsed or otherwise is in proper form for transfer, and (ii) such Person shall either (A) pay any transfer or other tax required by reason of such issuance or (B) establish to the reasonable satisfaction of the Surviving Corporation that such tax has been paid or is not applicable. Until surrendered in accordance with the provisions of this Section 2.04, from and after the Effective Time, each Endwave Certificate (except an Endwave Certificate representing Dissenting Shares) shall be deemed to represent, for all purposes other than payment of dividends, the right to receive a certificate representing the number of full shares of GigOptix Common Stock as determined in accordance with this Article II and cash in lieu of fractional shares as provided in Section 2.01(f).

(d) No dividend or other distribution shall be paid or declared with respect to GigOptix Common Stock prior to the Effective Time. No dividend or other distribution declared with respect to GigOptix Common Stock with a record date after the Effective Time will be paid to Holders of unsurrendered Endwave Certificates until such Holders surrender their Endwave Certificates. Upon the surrender of such Endwave Certificates, there shall be paid to such Holders, promptly after such surrender, the amount of dividends or other distributions, excluding interest, declared with a record date after the Effective Time and not paid because of the failure to surrender Endwave Certificates for exchange.

(e) Notwithstanding anything to the contrary in this Agreement, neither the Exchange Agent, GigOptix, the Surviving Corporation nor any party hereto shall be liable to any Holder for shares of GigOptix Common Stock or cash in lieu of fractional shares delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

issuance thereof, require the owner of such lost, stolen or destroyed Endwave Certificates to deliver a bond in such sum as it may reasonably direct as indemnity against any claim that may be made against GigOptix or the Exchange Agent with respect to the Endwave Certificates alleged to have been lost, stolen or destroyed.

From and after the Effective Time, a holder of Dissenting Shares shall not be entitled to exercise any of the voting rights or other rights of a stockholder of the Surviving Corporation.

(b) Notwithstanding the provisions of Section 2.01(a), if any Endwave Stockholder who demands appraisal of such shares under Delaware Law shall effectively withdraw or lose (through failure to perfect or otherwise) the right to appraisal, then, as of the later of the Effective Time and the occurrence of such event, such Endwave Stockholder’s shares shall no longer be Dissenting Shares and shall automatically be converted into and represent only the right to receive the Merger Consideration as provided in Section 2.01(a), without interest thereon, upon surrender of the certificate representing such shares pursuant to Section 2.04.

(c) Endwave shall give GigOptix (i) prompt notice of any written demands for appraisal of any shares of Endwave Common Stock, withdrawals of such demands, and any other instruments served pursuant to Delaware Law and received by Endwave which relate to any such demand for appraisal and (ii) the opportunity to participate in all negotiations and proceedings which take place prior to the Effective Time with respect to demands for appraisal under Delaware Law.

Each such Contract described in clauses (i) through (iii) is referred to herein as an “Endwave Material Contract.”

(b) Each of the Endwave Material Contracts is valid and binding on Endwave or its Subsidiaries, as the case may be, and, to the knowledge of Endwave, each other party thereto and is in full force and effect, except for such failures to be valid and binding or to be in full force and effect as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. There is no default under any Endwave Material Contract by Endwave or its Subsidiaries and no event has occurred that with the lapse of time or the giving of notice or both would constitute a default thereunder by Endwave or its Subsidiaries, in each case except as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(c) Notwithstanding anything in this Section 3.11, “Endwave Material Contract” shall not include any Contract that (i) is terminable upon ninety (90) days’ or less notice without a penalty premium and does not contain payment obligations of Endwave or its Subsidiaries in excess of $100,000 or (ii) is solely between Endwave and one or more of its Subsidiaries or is solely between Subsidiaries of Endwave.

(a) Endwave and each of its Subsidiaries have performed all material obligations required to be performed by each of them to date under the Endwave Material Contracts, and there exists no material default or event of

default or event, occurrence, condition or act, with respect to Endwave or any of its Subsidiaries, to the knowledge of Endwave, with respect to any other contracting party, which, with the giving of notice, the lapse of time or the happening of any other event or conditions, would reasonably be expected to (i) become a material default or event of default under any Endwave Material Contract or (ii) give any third party (1) the right to declare a default or exercise any remedy under any Endwave Material Contract, (2) the right to a rebate, chargeback, refund, credit, penalty or change in delivery schedule under any Endwave Material Contract, (3) the right to accelerate the maturity or performance of any obligation of Endwave under any Endwave Material Contract, or (4) the right to cancel, terminate or modify any Endwave Material Contract, except in each case for those breaches or defaults which, individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect on Endwave.

As used in this Agreement, “Endwave-Owned IP Rights” means Endwave IP Rights that are owned or purported to be owned by Endwave or its Subsidiaries; and “Endwave-Licensed IP Rights” means Endwave IP Rights that are licensed to Endwave or its Subsidiaries by a third party.

(b) Neither the execution, delivery and performance of this Agreement nor the consummation of the Merger and the other transactions contemplated by this Agreement shall, pursuant to any Contract to which Endwave or its Subsidiaries is a party, in accordance with its terms: (i) constitute a material breach of or default under any such Contract governing any Endwave IP Right (collectively, the “Endwave IP Rights Agreements”); (ii) cause the forfeiture or termination of, or give rise to a right of forfeiture or termination of, any Endwave IP Right; or (iii) materially impair the right of Endwave, its Subsidiaries or the Surviving Corporation to use, make, market, license, sell, copy, distribute, or dispose of any Endwave IP Right or portion thereof. Except as set forth in Section 3.13(b) of the Endwave Disclosure Schedule, there are no royalties, honoraria, fees or other payments payable by Endwave or its Subsidiaries to any third person (other than salaries payable to employees and independent contractors not contingent on or related to use of their work product) as a result of the ownership, use, manufacture, marketing, license-in, sale, copying, distribution, or disposition of any Endwave IP Rights by Endwave or its Subsidiaries, and no royalties, honoraria, fees or other payments shall become payable as a result of the consummation of the transactions contemplated by this Agreement in excess of those that would have been required to be paid had the parties to this Agreement not entered into this Agreement or consummated the transactions contemplated by this Agreement.

(c) To the knowledge of Endwave, neither the operation of the Endwave Business nor the use, development, manufacture, marketing, license, sale, distribution or furnishing of any product or service, including, without limitation, all software, firmware, middleware, databases, interfaces, systems, devices, hardware, equipment, other tangible items designed, developed, produced, manufactured, assembled, sold, leased, installed, repaired, licensed, marketed, furnished, distributed or otherwise made available by Endwave or its Subsidiaries (each an “Endwave Product or Service”) as designed, developed, produced, manufactured, assembled, sold, leased, installed, repaired, licensed, marketed, furnished, distributed or otherwise by Endwave and its Subsidiaries as of the date of this Agreement (i) violates any license or other Contract between Endwave or its Subsidiaries and any third party, or (ii) infringes or misappropriates any Intellectual Property right of any other party. There is no pending, or to the knowledge of Endwave, threatened in writing, claim or litigation contesting the validity, ownership or right of Endwave or its Subsidiaries to use, develop, make, market, license, sell, distribute or furnish any Endwave-Owned IP Right or Endwave Product or Service, nor to the knowledge of Endwave is there any legitimate basis for any such claim, nor since January 1, 2008 has Endwave or its Subsidiaries received any written notice asserting that any Endwave- Owned IP Right or the use, development, manufacture, marketing, licensing, sale, distribution, furnishing or disposition thereof conflicts with or infringes the rights of any other party, nor to the knowledge of Endwave is there any legitimate basis for any such assertion. Since January 1, 2008, Endwave and each of its Subsidiaries have not received any written notice from any third party notifying any of them of, or requesting that any of them enter into a license under, any third party patents. None of the Endwave-Owned IP Rights or Endwave Products or Services of Endwave or its Subsidiaries is subject to any proceeding or outstanding order or stipulation to which Endwave or any of its Subsidiaries is a party (i) restricting in any manner the use, development, manufacture, marketing, licensing, sale, distribution, furnishing or disposition by Endwave or its Subsidiaries of any Endwave-Owned IP Rights, any Endwave Product or Service, or which may affect the validity, use or enforceability of any such Endwave-Owned IP Rights or Endwave Product or Service, or (ii) restricting the conduct of the Endwave Business in order to accommodate Intellectual Property rights of a third party.

(d) To Endwave’s knowledge, no current or former employee, consultant or independent contractor of Endwave or any of its Subsidiaries: (i) is in material violation of any term or covenant of any employment contract, patent disclosure agreement, invention assignment agreement, nondisclosure agreement, noncompetition agreement or any other Contract with any other party by virtue of such employee’s, consultant’s or independent contractor’s being employed by, or performing services for, Endwave or any of its Subsidiaries or using trade secrets or proprietary information of others without permission; or (ii) has developed any technology, software or other copyrightable, patentable or otherwise proprietary work for Endwave or any of its Subsidiaries that is subject to any Contract under which such employee, consultant or independent contractor has assigned or otherwise granted to any third party any rights (including Intellectual Property) in or to such technology, software or other copyrightable, patentable or otherwise proprietary work except as directed by Endwave or any of its Subsidiaries. To Endwave’s knowledge, neither the employment of any employee of Endwave or any of its Subsidiaries, nor the use by Endwave or any of its Subsidiaries of the services of any consultant or independent contractor subjects Endwave or any of its Subsidiaries to any Liability to any third party (including for improperly soliciting such employee, consultant or independent contractor to work for Endwave or any of its Subsidiaries).

(e) Endwave and each of its Subsidiaries have taken commercially reasonable steps to protect, preserve and maintain the secrecy and confidentiality of the Endwave IP Rights and to preserve and maintain all Endwave’s and each of its Subsidiaries’ interests, proprietary rights and trade secrets in the Endwave IP Rights.

all such agreements have been delivered to GigOptix. Endwave, each of its Subsidiaries, and each of its and their predecessors have secured valid written assignments from all of their current and former consultants, independent contractors and employees who were involved in, or who contributed to, the creation or development of any material Endwave-Owned IP Rights, of the rights to such contributions that may be owned by such persons or that Endwave, each of its Subsidiaries, and each of its and their predecessors did not or do not already own by operation of law, except where such assignment is not permitted by Applicable Law. No current or former employee, officer, director, consultant or independent contractor of Endwave, any of its Subsidiaries or any of its or their predecessors has any right, license, claim or interest whatsoever in or with respect to any Endwave-Owned IP Rights.

(f) To the knowledge of Endwave, all registered patents, trademarks, service marks, Internet domain names, Internet or World Wide Web URLs or addresses, copyrights and mask work rights that are material Endwave-Owned IP Rights are valid and subsisting, and Endwave or its Subsidiaries are the record owner thereof. To the knowledge of Endwave, all registered patents, trademarks and service marks, are currently in compliance with all legal requirements other than any requirement, that if not satisfied, with respect to a patent would not result in a revocation or lapse or otherwise adversely affect its enforceability, and with regard to a trademark or service mark would not result in a cancellation of such registration or otherwise adversely affect the use, priority or enforceability of the trademark or service mark. To the knowledge of Endwave, Endwave, each of its Subsidiaries, and each of its and their predecessors have not taken any action or failed to take any action, or used or enforced (or failed to use or enforce) any of the patents for which any of them has applied for or been issued a registration in a manner that would result in the abandonment or unenforceability of such patent. Endwave or its Subsidiaries are the exclusive owners of all trademarks and, to the knowledge of Endwave, trade names used in connection with the operation or conduct of the Endwave Business, including the sale, licensing, distribution or provision of any Endwave Products or Services by Endwave or any of its Subsidiaries.

(g) Endwave or its Subsidiaries own all right, title and interest in and to all material Endwave-Owned IP Rights free and clear of all Encumbrances (other than Permitted Encumbrances) and licenses (other than licenses and rights listed in Section 3.13(g) of the Endwave Disclosure Schedule and non-exclusive licenses provided on Endwave’s or its Subsidiary’s standard form of agreement, without material deviation).

(h) Except as set forth in Section 3.13(h)-1 of the Endwave Disclosure Schedule or in a standard customer agreement for Endwave and its Subsidiaries, there are no unfulfilled performance commitments under any license, sublicense or Contract, including specified upgrades and undelivered elements, except for maintenance services which have not yet been provided as it related to undelivered elements. Except as set forth on Section 3.13(h)-2 of the Endwave Disclosure Schedule, none of the licenses or other Contracts of Endwave grants any third party exclusive rights to or under any Endwave-Owned IP Rights or grants any third party the right to sublicense any of such Endwave-Owned IP Rights. Endwave and each of its Subsidiaries have not transferred ownership of any Intellectual Property that is owned by Endwave or any of its Subsidiaries to any third party, or knowingly permitted Endwave’s or any of its Subsidiaries’ rights in such Intellectual Property to lapse or enter the public domain (other than through the expiration of registered Intellectual Property at the end of its statutory term).

(a) To the knowledge of Endwave, Endwave and each of its Subsidiaries have always been and currently are in compliance in all material respects with all Applicable Law and Contracts relating to employment, employment practices, immigration, wages, hours, and terms and conditions of employment, including employee compensation matters, and have correctly classified employees as exempt employees and nonexempt employees under the Fair Labor Standards Act and the California Labor Code. To the knowledge of Endwave, all employees of Endwave and each of its Subsidiaries are legally permitted to be employed by Endwave and such Subsidiary in

the jurisdiction in which such employee is employed in their current job capacities for the maximum period allowed under Applicable Law. To Endwave’s knowledge, all independent contractors providing services to Endwave and each of its Subsidiaries have been properly classified as independent contractors for purposes of federal and applicable state tax laws, laws applicable to employee benefits and other Applicable Law. Except as set forth on Section 3.16(a) of the Endwave Disclosure Schedule, Endwave and each of its Subsidiaries do not have any employment or consulting Contracts currently in effect that are not terminable at will (other than agreements with the sole purpose of providing for the confidentiality of proprietary information or assignment of inventions).

Endwave and each of its Subsidiaries are not subject to any collective bargaining agreement with respect to any of their employees, subject to any other Contract with any trade or labor union, employees’ association or similar organization, or subject to any current disputes with a labor organization.

As of the date of this Agreement, Endwave has no knowledge of any facts indicating that any Endwave employee has filed or intends to file an internal or external complaint regarding his or her employment at Endwave, including, without limitation, complaints of discriminations, harassment, retaliation, and / or unpaid wages.

No pension plan of Endwave or an ERISA Affiliate of Endwave is subject to Title IV of ERISA.

(d) Each employment, consulting, severance or other similar written Contract, each “employee benefit plan” as defined in Section 3(3) of ERISA and each written plan or arrangement providing for insurance coverage (including any self-insured arrangements that are clearly identified as such), workers’ benefits, vacation benefits, severance benefits, disability benefits, death benefits, hospitalization benefits, retirement benefits, deferred compensation, profit-sharing, bonuses, stock options, stock purchase, phantom stock, stock appreciation or other forms of incentive compensation or post-retirement insurance, compensation or benefits for employees, consultants or directors that is entered into, maintained or contributed to by Endwave, any Subsidiary of Endwave or any ERISA Affiliate of Endwave and covers any employee or former employee of Endwave, its predecessors or any Subsidiary of Endwave or ERISA Affiliate of Endwave (excluding any government plans, programs or mandates) (collectively referred to as “Endwave Benefit Arrangements”) have been maintained, including as to form, in compliance in all material respects with their terms and with the requirements prescribed by any and all Applicable Law.

Benefit Arrangements and that is reasonably likely to subject Endwave, any of the its Subsidiaries, or any of their employees to a material tax or penalty on prohibited transactions imposed by Section 4975 of the Code or material sanctions imposed under Title I of ERISA.

Except as set forth on Section 3.16(h) to the Endwave Disclosure Schedule, the execution of this Agreement and the consummation of the transactions contemplated by this Agreement will not (either alone or in connection with the termination of employment or change of position of any employee following or in connection with the consummation of the Merger) constitute an event under any Endwave Benefit Arrangement that will or may result in any material payment (whether severance pay or otherwise), acceleration of payment, forgiveness of indebtedness, vesting, distribution, increase in benefits or obligation to fund benefits with respect to any employee.

(i) Except as set forth on Section 3.16(i) to the Endwave Disclosure Schedule, no benefit payable or that may become payable by Endwave or any of its Subsidiaries pursuant to any Endwave Benefit Arrangement as a result of, in connection with or arising under this Agreement or the Certificate of Merger shall constitute a “parachute payment” (as defined in Section 280G(b)(2) of the Code) that is subject to the imposition of an excise tax under Section 4999 of the Code or that would not be deductible by reason of Section 280G of the Code.

Endwave and each of its Subsidiaries have no obligation to pay any material amount or provide any material benefit to any former employee or officer, other than obligations (i) for which Endwave has established a reserve for such amount on the Endwave Balance Sheet, (ii) pursuant to Contracts entered into after the Endwave Balance Sheet Date and disclosed on Section 3.16(i) of the Endwave Disclosure Schedule and (iii) arising from governmentally mandated benefits.

of its Subsidiaries or to use trade secrets or proprietary information of others. To Endwave’s knowledge, the employment of any employee or consultant by Endwave and each of its Subsidiaries does not subject it to any material Liability to any third party other than Liabilities with respect to employer payroll tax and employee tax withholding.

(k) Endwave and each of its Subsidiaries have not established any compensation or benefit plan that is maintained or is required to be maintained or contributed to by the law or applicable custom or rule of a jurisdiction outside of the United States.

(n) The form of each Endwave Benefit Arrangement that is subject to Section 409A of the Code meets the requirements of Sections 409A(a)(2), (3) and (4) of the Code and has been operated in accordance with such requirements.

Section 3.18 of the Endwave Disclosure Schedule sets forth the name of the insurer under each such policy and bond, the type of policy or bond, and the coverage amount and any applicable deductible. There is no material claim pending under any of such policies or bonds as to which coverage has been questioned, denied or disputed by the underwriters of such policies or bonds. All premiums due and payable under all such policies and bonds have been timely paid, and Endwave and each of its Subsidiaries are otherwise in compliance in all material respects with the terms of such policies and bonds. All such policies and bonds remain in full force and effect, and Endwave has no knowledge of any threatened termination of, or material premium increase with respect to, any of such policies or bonds. All such policies provide insurance coverage for Endwave’s or its Subsidiaries assets and operation of the Endwave Business, of the kinds, in the amounts and against the risks required to comply with Applicable Law and/or any contractual or other obligations, and such policies are of the scope and amount customary and reasonable for the businesses in which Endwave and its Subsidiaries has engaged. Neither Endwave nor any of its Subsidiaries has been refused any insurance with respect to any aspect of the operations of its business, nor has its coverage been limited by any insurance carrier to which it has applied for insurance or with which it has carried insurance. The activities and operations of Endwave and each of its Subsidiaries have been conducted in a manner so as to materially conform to all

applicable provisions of such policies and bonds. Endwave has delivered to GigOptix correct and complete copies of all such policies of insurance and bonds issued at the request or for the benefit of Endwave.

Since January 1, 2011, GigOptix has not received any written notice from any GigOptix Significant Supplier that such supplier shall not continue as a supplier to GigOptix or any of its Subsidiaries or that such supplier intends to terminate or materially modify existing Contracts with GigOptix (or the Surviving Corporation, Endwave or any of its Subsidiaries). GigOptix has access, on commercially reasonable terms, to all products and services reasonably necessary to carry on the GigOptix Businesses, and GigOptix has no knowledge of any reason why it will not continue to have such access on commercially reasonable terms.

Section 4.25 Reorganization. None of GigOptix, any of its Subsidiaries nor, to the knowledge of GigOptix, any of GigOptix’s Affiliates has taken or agreed to take any action that would prevent the Merger from qualifying as a “reorganization” within the meaning of Section 368 of the Code and GigOptix is not aware of any agreement, plan or other circumstance that would prevent the Merger from qualifying as a “reorganization” within the meaning of Section 368 of the Code.

(a) From and after the Agreement Date until the Effective Time or termination of this Agreement pursuant to Article VIII, Endwave and its Subsidiaries will not, nor will they authorize or permit any of their respective officers, directors, affiliates or employees or any investment banker, attorney or other advisor or representative retained by any of them to, directly or indirectly, (i) solicit, initiate, encourage or induce the making, submission or announcement of any Endwave Acquisition Proposal (as hereinafter defined), (ii) participate in any discussions or negotiations regarding, or furnish to any person any non-public information with respect to, or take any other action to facilitate any inquiries or the making of any proposal that constitutes or may reasonably be expected to lead to, any Endwave Acquisition Proposal, (iii) engage in discussions with any person with respect to any Endwave Acquisition Proposal, except as to the existence of these provisions, (iv) approve, endorse or recommend any Endwave Acquisition Proposal or (v) enter into any letter of intent or similar document or any contract agreement or commitment contemplating or otherwise relating to any Endwave Acquisition Transaction. Notwithstanding anything to the contrary contained in this Section 5.02 or in any other provision of this Agreement, Endwave and its board of directors: (i) may furnish information to, or participate in discussions with, any third party that has made an unsolicited Endwave Acquisition Proposal (a “Potential Acquirer”) that the board of directors reasonably concludes may lead to an Endwave Superior Offer (as defined in Section 5.04(c) hereof); and (ii) may participate in discussions or negotiations with any Potential Acquirer or approve an unsolicited Endwave Acquisition Proposal if the board of directors is advised by its financial advisor that the Potential Acquirer submitting such Endwave Acquisition Proposal has the financial wherewithal to be reasonably capable of consummating such an Endwave Acquisition Proposal, and the board of directors determines in good faith, (A) after receiving advice from its financial advisor, that such Endwave Acquisition Proposal is an Endwave Superior Offer (as defined in Section 5.04(c) hereof), and (B) after consultation with its legal counsel, that the failure to participate in such discussions or negotiations or to furnish such information or approve an Endwave Acquisition Proposal would be inconsistent with the board of directors’ fiduciary duties under Applicable Law. Endwave agrees that any non-public information furnished to a Potential Acquirer will be pursuant to a confidentiality, standstill and nonsolicitation agreement containing provisions at least as favorable to Endwave as the confidentiality, standstill and nonsolicitation provisions of the Confidentiality Agreement (as defined in Section 5.03). In the event that Endwave shall determine to provide any information as described

above, or shall receive any Endwave Acquisition Proposal (or any material amendment to an Endwave Acquisition Proposal previously received), it shall promptly, and in any event within 24 hours, inform GigOptix in writing as to that fact and shall furnish to GigOptix the identity of the recipient of such information to be provided and/or the Potential Acquirer and the terms of such Endwave Acquisition Proposal (or material amendment). For purposes of this Agreement, “Endwave Acquisition Proposal” shall mean any offer or proposal (other than an offer or proposal by GigOptix) relating to any Endwave Acquisition Transaction. For purposes of this Agreement, “Endwave Acquisition Transaction” shall mean any transaction or series of related transactions involving: (A) any purchase from Endwave or acquisition by any person or “group” (as defined under Section 13(d) of the Exchange Act and the rules and regulations thereunder) of more than a 30% interest in the total outstanding voting securities of Endwave or any of its subsidiaries or any tender offer or exchange offer that if consummated would result in any person or “group” (as defined under Section 13(d) of the Exchange Act and the rules and regulations thereunder) beneficially owning 30% or more of the total outstanding voting securities of Endwave or any of its subsidiaries or any merger, consolidation, business combination or similar transaction involving Endwave; (B) any sale, lease (other than in the ordinary course of business), exchange, transfer, license (other than in the ordinary course of business), acquisition or disposition of more than 30% of the assets of Endwave; or (C) any liquidation or dissolution of Endwave.

(b) In addition to the obligations of Endwave set forth in Section 5.02(a), Endwave as promptly as practicable shall advise GigOptix orally and in writing of any Endwave Acquisition Proposal or any request for non-public information or inquiry which Endwave reasonably believes would lead to an Endwave Acquisition Proposal or to any Endwave Acquisition Transaction, the material terms and conditions of such Endwave Acquisition Proposal, request or inquiry, and the identity of the person or group making any such Endwave Acquisition Proposal, request or inquiry. Endwave will keep GigOptix informed as promptly as practicable in all material respects of the status and details (including material amendments or proposed material amendments) of any such Endwave Acquisition Proposal, request or inquiry.

(c) From and after the Agreement Date until the Effective Time or termination of this Agreement pursuant to Article VIII, GigOptix and its Subsidiaries will not, nor will they authorize or permit any of their respective officers, directors, affiliates or employees or any investment banker, attorney or other advisor or representative retained by any of them to, directly or indirectly, (i) solicit, initiate, encourage or induce the making, submission or announcement of any GigOptix Acquisition Proposal (as hereinafter defined), (ii) participate in any discussions or negotiations regarding, or furnish to any person any non-public information with respect to, or take any other action to facilitate any inquiries or the making of any proposal that constitutes or may reasonably be expected to lead to, any GigOptix Acquisition Proposal, (iii) engage in discussions with any person with respect to any GigOptix Acquisition Proposal, except as to the existence of these provisions, (iv) approve, endorse or recommend any GigOptix Acquisition Proposal or (v) enter into any letter of intent or similar document or any contract agreement or commitment contemplating or otherwise relating to any GigOptix Acquisition Transaction. For purposes of this Agreement, “GigOptix Acquisition Proposal” shall mean any offer or proposal (other than an offer or proposal by GigOptix) relating to any GigOptix Acquisition Transaction. For purposes of this Agreement, “GigOptix Acquisition Transaction” shall mean any transaction or series of related transactions involving: (A) any purchase from GigOptix or acquisition by any person or “group” (as defined under Section 13(d) of the Exchange Act and the rules and regulations thereunder) of more than a 30% interest in the total outstanding voting securities of GigOptix or any of its subsidiaries or any tender offer or exchange offer that if consummated would result in any person or “group” (as defined under Section 13(d) of the Exchange Act and the rules and regulations thereunder) beneficially owning 30% or more of the total outstanding voting securities of GigOptix or any of its subsidiaries or any merger, consolidation, business combination or similar transaction involving GigOptix; (B) any sale, lease (other than in the ordinary course of business), exchange, transfer, license (other than in the ordinary course of business), acquisition or disposition of more than 30% of the assets of GigOptix; or (C) any liquidation or dissolution of GigOptix.

(d) Notwithstanding anything contained in Section 5.02(c), prior to the Effective Time, GigOptix may furnish nonpublic information regarding GigOptix to, and enter into discussions or negotiations with, any Person

in response to an unsolicited, bona fide written GigOptix Acquisition Proposal made or received after the date of this Agreement, which GigOptix’s board of directors determines in good faith constitutes, or is reasonably likely to result in, a GigOptix Superior Offer (and is not withdrawn) if: (A) neither GigOptix nor any representative of GigOptix shall have failed to comply with this Section; (B) the board of directors of GigOptix concludes in good faith, after consultation with outside counsel, that the failure to take such action would result in a breach of the fiduciary duties of the board of directors of GigOptix under Applicable Law; (C) within 24 hours following the furnishing of any such nonpublic information to, or entering into discussions with, such Person, GigOptix gives Endwave written notice of the identity of such Person and of GigOptix’s intention to furnish nonpublic information to, or enter into discussions with, such Person or has furnished, or entered into discussions with, such Person. For purposes of this Agreement, “GigOptix Superior Offer” shall mean an unsolicited, bona fide written offer made by a third party to consummate any of the following transactions: (i) a merger or consolidation involving GigOptix pursuant to which the stockholders of GigOptix immediately preceding such transaction hold less than a majority of the equity interest in the surviving or resulting entity of such transaction or (ii) the acquisition by any person or group (including by way of a tender offer or an exchange offer or a two step transaction involving a tender offer followed with reasonable promptness by a cash-out merger involving GigOptix), directly or indirectly, of ownership of 90% of the then outstanding shares of capital stock of GigOptix, on terms that the board of directors of GigOptix determines, in its reasonable judgment (based on the advice of counsel and the written advice of its financial advisor) to be an offer that the GigOptix board of directors must consider in order to fulfill its fiduciary duties; provided, however, that any such offer shall not be deemed to be an “GigOptix Superior Offer” if any financing required to consummate the transaction contemplated by such offer is not committed and is not likely in the reasonable judgment of GigOptix board of directors (based on the advice of its financial advisor) to be obtained by such third party on a timely basis.

Section 5.03 Access to Information. From the Agreement Date until the Effective Time, Endwave and GigOptix will each afford to the other and their authorized representatives (including counsel, environmental and other consultants, accountants, auditors and agents) reasonable access during normal business hours and upon reasonable notice to all of its facilities, personnel and operations and to all of its and its Subsidiaries’ Books and Records, will permit the other and its authorized representatives to conduct inspections as they may reasonably request and will instruct its officers and those of its Subsidiaries to furnish such persons with such financial and operating data and other information with respect to its business and properties as they may from time to time reasonably request, subject to the restrictions set forth in the Confidentiality Agreement between GigOptix and Endwave (the “Confidentiality Agreement”). GigOptix and Merger Sub agree that each of them will treat any such information in accordance with the Confidentiality Agreement, which shall remain in full force and effect in accordance with its terms.

Section 5.04 Special Meetings; Registration Statement; Board Recommendations.

(a) Endwave Special Meeting. Promptly after the date hereof, subject to Section 5.04(c) and 5.04(e), Endwave will take all action necessary in accordance with Delaware Law and its Amended and Restated Certificate of Incorporation and bylaws to convene a meeting of Endwave Stockholders to consider adoption of this Agreement and approval of the Merger (the “Endwave Special Meeting”) to be held as promptly as practicable, and in any event (to the extent permissible under Applicable Law) within 45 days after the declaration of effectiveness of the Registration Statement. Subject to Section 5.04(c), Endwave will use its commercially reasonable efforts to solicit from its stockholders proxies in favor of the adoption of this Agreement and the approval of the Merger and will take all other action necessary or advisable to secure the vote or consent of its stockholders required by the rules of the NASDAQ Stock Market LLC (“NASDAQ”) or Delaware Law to obtain such approvals. Notwithstanding anything to the contrary contained in this Agreement, Endwave may adjourn or postpone the Endwave Special Meeting to the extent necessary to ensure that any necessary supplement or amendment to the Proxy Statement is provided to Endwave’s stockholders in advance of a vote on the Merger and this Agreement or, if as of the time for which the Endwave Special Meeting is originally scheduled (as set forth in the Proxy Statement) there are insufficient shares of Endwave Common Stock represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of the

Endwave Special Meeting. Endwave shall ensure that the Endwave Special Meeting is called, noticed, convened, held and conducted, and that all proxies solicited by Endwave in connection with the Endwave Special Meeting are solicited, in compliance with the Delaware Law, the Endwave Charter Documents, the rules of NASDAQ and all other applicable legal requirements.

(b) Subject to Section 5.04(c): (i) the board of directors of Endwave shall unanimously recommend that Endwave’s stockholders vote in favor of and adopt and approve this Agreement and approve the Merger at the Endwave Special Meeting; (ii) the Proxy Statement shall include a statement to the effect that the board of directors of Endwave has unanimously recommended that Endwave’s stockholders vote in favor of and adopt and approve this Agreement and the Merger at the Endwave Special Meeting; and (iii) neither the board of directors of Endwave nor any committee thereof shall withdraw, amend or modify, or propose or resolve to withdraw, amend or modify in a manner adverse to GigOptix, the unanimous recommendation of the board of directors of Endwave that Endwave’s stockholders vote in favor of and adopt and approve this Agreement and the Merger. For purposes of this Agreement, said recommendation of the board of directors shall be deemed to have been modified in a manner adverse to GigOptix if said recommendation shall no longer be unanimous, provided that, for all purposes of this Agreement, an action by any board of directors or committee thereof shall be unanimous if each member of such board of directors or committee has approved such action other than (i) any such member who has appropriately abstained from voting on such matter because of an actual or potential conflict of interest and (ii) any such member who is unable to vote in connection with such action as a result of death or disability.

(c) Nothing in this Agreement shall prevent the board of directors of Endwave from withholding, withdrawing, amending or modifying its unanimous recommendation in favor of the Merger if (i) an Endwave Superior Offer (as defined below) is made to Endwave and is not withdrawn, (ii) Endwave shall have provided written notice to GigOptix (a “Notice of Endwave Superior Offer”) advising GigOptix that Endwave has received an Endwave Superior Offer, specifying the material terms and conditions of such Endwave Superior Offer and identifying the person or entity making such Endwave Superior Offer, (iii) GigOptix shall not have, within five business days of GigOptix’s receipt of the Notice of Endwave Superior Offer, made an offer that the board of directors of Endwave by a majority vote determines in its good faith judgment (based on the written advice of its financial advisor) to be at least as favorable to Endwave’s stockholders as such Endwave Superior Offer (it being agreed that the board of directors Endwave shall convene a meeting to consider any such offer by GigOptix promptly following the receipt thereof), (iv) the board of directors of Endwave concludes in good faith, after consultation with its outside counsel, that, in light of such Endwave Superior Offer, the failure to withhold, withdraw, amend or modify such recommendation would be inconsistent with the fiduciary obligations of the board of directors of Endwave to Endwave’s stockholders under Applicable Law and (v) Endwave shall not have violated any of the restrictions set forth in Section 5.02 or this Section 5.04(c). Endwave shall provide GigOptix with at least three business days prior notice (or such lesser prior notice as provided to the members of Endwave’s board of directors but in no event less than twenty-four hours) of any meeting of Endwave’s board of directors at which Endwave’s board of directors is reasonably expected to consider any Endwave Acquisition Transaction. For purposes of this Agreement, “Endwave Superior Offer” shall mean an unsolicited, bona fide written offer made by a third party to consummate any of the following transactions: (i) a merger or consolidation involving Endwave pursuant to which the stockholders of Endwave immediately preceding such transaction hold less than a majority of the equity interest in the surviving or resulting entity of such transaction or (ii) the acquisition by any person or group (including by way of a tender offer or an exchange offer or a two step transaction involving a tender offer followed with reasonable promptness by a cash-out merger involving Endwave), directly or indirectly, of ownership of 90% of the then outstanding shares of capital stock of Endwave, on terms that the board of directors of Endwave determines, in its reasonable judgment (based on the written advice of its financial advisor) to be more favorable to Endwave stockholders than the terms of the Merger; provided, however, that any such offer shall not be deemed to be an “Endwave Superior Offer” if any financing required to consummate the transaction contemplated by such offer is not committed and is not likely in the reasonable judgment of Endwave’s board of directors (based on the advice of its financial advisor) to be obtained by such third party on a timely basis.

(d) Nothing contained in this Agreement shall prohibit Endwave or its board of directors from taking and disclosing to its stockholders a position contemplated by Rules 14d-9 and 14e-2 promulgated under the Exchange Act.

(e) As promptly as practicable after the execution of this Agreement, Endwave and GigOptix shall mutually prepare, and GigOptix shall file with the SEC, the Registration Statement including the preliminary Proxy Statement. Prior to the effectiveness of the Registration Statement: (a) Endwave shall execute and deliver to Cooley LLP and to Nixon Peabody LLP a tax representation letter in a customary form to be mutually agreed to by the parties; and (b) GigOptix and Merger Sub shall execute and deliver to Cooley LLP and Nixon Peabody LLP a tax representation letter in a customary form to be mutually agreed to by the parties. To the extent requested by GigOptix or Endwave, each of GigOptix, Merger Sub and Endwave shall confirm to Cooley LLP and to Nixon Peabody LLP the accuracy and completeness as of the Effective Time of the tax representation letters delivered pursuant to the immediately preceding sentence. Following the delivery of the tax representation letters pursuant to the second sentence of this Section 5.04(e): (a) GigOptix shall use commercially reasonable efforts to cause Nixon Peabody LLP to deliver to it a tax opinion satisfying the requirements of Item 601 of Regulation S-K under the Securities Act; and (b) Endwave shall use its reasonable best efforts to cause Cooley LLP to deliver to it a tax opinion satisfying the requirements of Item 601 of Regulation S-K under the Securities Act. In rendering such opinions, each of such counsel shall be entitled to rely on the tax representation letters referred to in this Section 5.04(e). GigOptix and Endwave shall use all commercially reasonable efforts to have the preliminary Proxy Statement cleared by the SEC and the Registration Statement declared effective by the SEC as promptly as practicable. As promptly as practicable following receipt of SEC comments on such Registration Statement and preliminary Proxy Statement, GigOptix and Endwave shall mutually prepare a response to such comments. Upon resolution of all comments, GigOptix shall file the Registration Statement with the SEC, in which the Proxy Statement will be included, as a prospectus. GigOptix shall also take any action required to be taken under applicable state blue sky or securities laws in connection with GigOptix Common Stock to be issued in exchange for the shares of Endwave Common Stock. GigOptix and Endwave shall promptly furnish to each other all information, and take such other actions (including without limitation using all commercially reasonable efforts to provide any required consents of their respective independent auditors), as may reasonably be requested in connection with any action by any of them in connection with the preceding sentences of this Section 5.04(e). Whenever any party learns of the occurrence of any event which is required to be set forth in an amendment or supplement to the Proxy Statement, the Registration Statement or any other filing made pursuant to this Section 5.04(e), GigOptix or Endwave, as the case may be, shall promptly inform the other of such occurrence and cooperate in filing with the SEC or its staff and/or mailing to stockholders of Endwave such amendment or supplement.

(f) As promptly as practical after the execution of this Agreement, GigOptix shall prepare and make such filings as are required under applicable blue sky laws for the purpose of obtaining necessary permits and qualifications (to the extent that exemptions from the need to obtain such permits or qualifications are not available) in connection with the issuance of GigOptix Common Stock in the Merger or pursuant to Section 2.02 in such jurisdictions for which Endwave and GigOptix determine such filings are required to be made. Endwave shall provide promptly all information in its possession that is reasonably requested by GigOptix for the purpose of compliance with this Section 5.04(f).

(a) Subject to the terms and conditions herein provided, GigOptix, Merger Sub and Endwave shall use commercially reasonable efforts to take, or cause to be taken, all actions and do, or cause to be done, all things necessary, proper or appropriate under this Agreement, Applicable Laws to consummate and make effective the transactions contemplated by this Agreement, including, without limitation, (i) using commercially reasonable efforts to obtain all necessary governmental and private party consents, approvals or waivers, and (iii) using commercially reasonable efforts to lift any legal bar to the Merger. GigOptix shall cause Merger Sub to perform all of its obligations under this Agreement. Without limiting the foregoing, in the event that any submission is

required under the Antitrust Laws, GigOptix Merger Sub, and Endwave will as soon as reasonably practicable after the date of this Agreement and in no event later than 10 business days after the date of this Agreement, for any obligations triggered by the HSR Act, and in no event later than 15 business days, for any obligations triggered by any of the other Antitrust Laws, file or cause to be filed all notices, reports and other documents required to be filed by such party with any Governmental Authority with respect to the transactions contemplated by this Agreement to initiate the approval process. Each of GigOptix, Merger Sub and Endwave shall promptly (1) supply the other party with any information that may be required in order to effectuate notices, reports, documents or other filings with any Governmental Authority required to be made pursuant to any Antitrust Laws, (2) supply any additional information which reasonably may be required by any Governmental Authority in connection with any submission required under the Antitrust Laws, and (3) promptly inform the other party of the substance of any communication to or from any Governmental Authority regarding the transactions contemplated by this Agreement.

(b) Notwithstanding anything to the contrary in this Agreement, neither GigOptix, nor the Surviving Corporation, nor any of their Subsidiaries shall be required to (i) divest, hold separate or license any business(es), product line(s) or asset(s), (ii) take any action or accept any limitation that would reasonably be expected to have a GigOptix Material Adverse Effect or an Endwave Material Adverse Effect, or (iii) agree to any of the foregoing.

Section 5.06 Public Announcements. Before issuing any press release or otherwise making any public statement with respect to the Merger or any of the other transactions contemplated hereby, GigOptix, Merger Sub and Endwave agree to consult with each other as to its form and substance, and agree not to issue any such press release or general communication to employees or make any public statement prior to obtaining the consent of the other (which shall not be unreasonably withheld, conditioned or delayed), except as may be required by Applicable Law or by the rules and regulations of or listing agreement with NASDAQ or as may otherwise be required by NASDAQ or the SEC.

Section 5.07 Notification of Certain Matters. Each of Endwave and GigOptix shall promptly notify the other party of the occurrence or non-occurrence of any event the respective occurrence or non-occurrence of which would be reasonably likely to cause any condition to the obligations of the notifying party to effect the Merger not to be fulfilled. Each of Endwave and GigOptix shall also give prompt notice to the other of any communication from any Person alleging that the consent of such Person is or may be required in connection with the Merger or other transactions contemplated hereby.

GigOptix shall use commercially reasonable efforts to cause the GigOptix Common Stock issuable pursuant to Section 2.01 to be authorized for listing on the NYSE AMEX, subject to official notice of issuance, prior to the Closing Date, and if that is not reasonably possible, then as soon thereafter as is reasonably possible. If within 60 days following the Effective Time, such shares of GigOptix Common Stock has not been so authorized, then the board of directors of GigOptix will use its best efforts to take further actions as appropriate to achieve such listing on NYSE AMEX, subject to official notice of issuance.

Section 5.09 Resignation of Directors and Officers.

Not later than each such director’s appointment to the board of directors, GigOptix will enter into an indemnity agreement with each director in the same form as then exists between GigOptix and each of its other directors. Such directors shall be entitled to the same compensation as all other GigOptix non-employee directors.

(a) GigOptix shall, or shall cause the Surviving Corporation to, fulfill and honor the obligation of Endwave to Endwave’s present and former directors and officers (the “Indemnified Directors and Officers”) pursuant to the terms of Endwave’s Amended and Restated Certificate of Incorporation and bylaws.

(b) Notwithstanding anything else set forth in this Agreement, (i) this Section 5.11 shall survive the consummation of the Merger, (ii) is intended to benefit the Indemnified Directors and Officers and their respective heirs and (iii) is in addition to, and not in substitution for, any other rights to indemnification or contribution that any such Person may have against GigOptix or the Surviving Corporation first arising after the Closing Date by contract or otherwise. This Section 5.11 shall not be terminated or modified in such a manner as to adversely affect the rights of any Indemnified Director and Officer under this Section 5.11 without the written consent of such affected Indemnified Director and Officer.

(c) From the Effective Time until the sixth anniversary of the Effective Time, neither GigOptix nor the Surviving Corporation shall take any action to terminate any liability insurance that Endwave acquires and fully pays for prior to the Effective Time with respect to claims arising against Endwave’s officers and directors with respect to their acts and omissions as directors and officers of Endwave occurring prior to the Effective Time (the “Tail Policy”); provided that the Surviving Corporation may, but under no circumstances shall be obligated to, substitute a policy of at least the same coverage containing terms and conditions that, in the aggregate, are no less advantageous. Endwave shall purchase the Tail Policy, which for clarity, would constitute a Merger Expense.

Section 5.12 Consents of GigOptix’s and Endwave’s Accountants. Each of GigOptix and Endwave shall use commercially reasonable efforts to cause its independent accountants to deliver to GigOptix a consent, dated the date on which the Registration Statement shall become effective, in form reasonably satisfactory to GigOptix and customary in scope and substance for consents delivered by independent public accountants in connection with registration statements on Form S-4 under the Securities Act.

Section 5.13 Notification of Certain Matters. Endwave shall give prompt notice to GigOptix and Merger Sub, and GigOptix and Merger Sub shall give prompt notice to Endwave, of (i) the occurrence or nonoccurrence of any event the occurrence or nonoccurrence of which would be likely to cause any representation or warranty contained in this Agreement to be untrue or inaccurate such that the condition in Section 7.01(a) or 7.02(a), as applicable, would not be satisfied, (ii) any material failure of the Endwave, GigOptix or Merger Sub, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder such that the condition in Section 7.01(b) or 7.02(b), as applicable, would not be satisfied, (iii) any notice or other communication from any third party alleging that the consent of such third party is or may be required in connection with the transactions contemplated by this Agreement, or (iv) any facts or circumstances that arise that could reasonably be expected to result in an Endwave Material Adverse Effect or a GigOptix Material Adverse Effect, as the case may be.

(a) Endwave will deliver promptly to GigOptix true and complete copies of each report, registration statement or statement mailed by it to its security holders generally or filed by it with the SEC, in each case subsequent to the Agreement Date and prior to the Effective Time. As of their respective dates, such reports, including the consolidated financial statements included therein, and statements (excluding any information therein provided by GigOptix or Merger Sub, as to which Endwave makes no representation) will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they are made, not misleading and will comply in all material respects with all applicable requirements of law. Each of the consolidated financial statements (including, in each case, any related notes hereto) contained in such reports, (x) shall comply as to form in all material respects with applicable accounting requirements and with the published rules and

regulations of the SEC with respect thereto, (y) shall be prepared in accordance with GAAP applied on a consistent basis throughout the periods involved (except as may be indicated in the notes thereto or, in the case of unaudited interim financial statements, as may be permitted by the SEC on Form 10-Q under the Exchange Act) and (z) shall fairly present the consolidated financial position of Endwave and its Subsidiaries as at the respective dates thereof and the consolidated results of its operations and cash flows for the periods indicated, except that the unaudited interim financial statements were or are subject to normal and recurring year-end adjustments which were not, or are not expected to be, material in amount.

(b) GigOptix will deliver promptly to Endwave true and complete copies of each report, registration statement or statement mailed by it to its security holders generally or filed by it with the SEC, in each case subsequent to the Agreement Date and prior to the Effective Time. As of their respective dates, such reports, including the consolidated financial statements included therein, and statements (excluding any information therein provided by Endwave, as to which GigOptix makes no representation) will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they are made, not misleading and will comply in all material respects with all applicable requirements of law. Each of the consolidated financial statements (including, in each case, any related notes hereto) contained in such reports, (x) shall comply as to form in all material respects with applicable accounting requirements and with the published rules and regulations of the SEC with respect thereto, (y) shall be prepared in accordance with GAAP applied on a consistent basis throughout the periods involved (except as may be indicated in the notes thereto or, in the case of unaudited interim financial statements, as may be permitted by the SEC on Form 10-Q under the Exchange Act) and (z) shall fairly present the consolidated financial position of GigOptix and its Subsidiaries as at the respective dates thereof and the consolidated results of its operations and cash flows for the periods indicated, except that the unaudited interim financial statements were or are subject to normal and recurring year-end adjustments which were not, or are not expected to be, material in amount.

Section 5.15 Employees. Endwave, prior to the Closing, and Surviving Corporation, immediately after the Effective Time and for such period of time as it determines in its sole discretion, shall continue the at-will employment of Endwave’s employees who remain employed by Endwave or its Subsidiaries at the Effective Time (the “Continuing Employees”) on terms and conditions commensurate with similarly situated employees of GigOptix or GigOptix’s Affiliates. Prior to the Effective Time, GigOptix shall make written offers of such employment terms and conditions, on behalf of the Surviving Corporation, to each Continuing Employee. Continuing Employees who are employed by the Surviving Corporation shall receive credit for service with Endwave and its Subsidiaries (including credit with predecessors recognized by Endwave and its Subsidiaries) for purposes of earning and accruing paid time off. Endwave shall, upon the request of GigOptix, take all required corporate action to terminate Endwave’s 401(k) plan, effective immediately prior to the Effective Time but contingent thereon. Endwave shall take all required corporate action to terminate all other Endwave Benefit Arrangements which it may terminate under Applicable Law and without the consent of any participants under such Endwave Benefit Arrangement, effective immediately prior to the Effective Time but contingent thereon.

Section 6.04 Governmental Clearances. Other than the filing of the Certificate of Merger which shall be accomplished as provided in Section 1.02, all authorizations, consents, orders or approvals of, or declarations or filings with, or expirations of waiting periods imposed by, any Government Entity, the failure of which to obtain or comply with would be reasonably likely to have an Endwave Material Adverse Effect or a GigOptix Material Adverse Effect, shall have been obtained or filed.

Section 6.05 Statute or Decree. No writ, order, temporary restraining order, preliminary injunction or injunction shall have been enacted, entered, promulgated or enforced by any court or other tribunal or governmental body or authority, which remains in effect, and prohibits the consummation of the Merger or otherwise makes it illegal, nor shall any governmental agency have instituted any action, suit or proceeding that remains pending and that seeks, and that is reasonably likely, to enjoin, restrain or prohibit the consummation of the Merger in accordance with the terms of this Agreement.

(b) by either Endwave or GigOptix if the Merger shall not have been consummated by June 30, 2011 (the “End Date”) for any reason; provided, however, that the right to terminate this Agreement under this

Section 8.01(b) shall not be available to any party whose action or failure to act has been a principal cause of or resulted in the failure of the Merger to occur on or before such date and such action or failure to act constitutes a material breach of a covenant of such party set forth in this Agreement;

(g) by GigOptix, upon a breach of any representation, warranty, covenant or agreement on the part of Endwave set forth in this Agreement, or if any representation or warranty of Endwave shall have become untrue, in either case such that the conditions set forth in Section 7.02(a) or Section 7.02(b) would not be satisfied as of the time of such breach or as of the time such representation or warranty shall have become untrue, provided that such inaccuracy in Endwave’s representations and warranties or breach by Endwave remains uncured on the date which is twenty business days following written notice of such breach or inaccuracy from GigOptix to Endwave (it being understood that GigOptix may not terminate this Agreement pursuant to this paragraph (g) if it shall have materially breached any of its covenants in this Agreement and remains in breach of such covenants as of the date of such termination);

Securities Act, within ten business days after such tender or exchange offer is first published, sent or given, a statement disclosing that Endwave recommends rejection of such tender or exchange offer.

Section 8.02 Notice of Termination; Effect of Termination. Any termination of this Agreement under Section 8.01 will be effective immediately upon the delivery of a valid written notice of the terminating party to the other parties hereto. In the event of the termination of this Agreement as provided in Section 8.01, this Agreement shall be of no further force or effect, except (i) as set forth in Section 5.03, this Section 8.02, Section 8.03 and Article IX, each of which shall survive the termination of this Agreement, and (ii) nothing herein shall relieve any party from liability for any willful breach of this Agreement. No termination of this Agreement shall affect the obligations of the parties contained in the Confidentiality Agreement, all of which obligations shall survive termination of this Agreement in accordance with their terms.

(a) General. Except as set forth in this Section 8.03, all fees and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such expenses whether or not the Merger is consummated; provided, however, that GigOptix and Endwave shall share equally all fees and expenses, other than attorneys’ and accountants’ fees and expenses, incurred in relation to the printing and filing (with the SEC) of the Proxy Statement (including any preliminary materials related thereto) and the Registration Statement (including financial statements and exhibits) and any amendments or supplements thereto.

(b) Endwave Payments. In the event that this Agreement is terminated by GigOptix or Endwave pursuant to Section 8.01(e), Endwave shall promptly, but in no event later than two days after the date of such termination, pay GigOptix a fee equal to $1,000,000, plus all reasonable documented expenses incurred by GigOptix in connection with this Agreement and the transactions contemplated hereby, in immediately available funds (the “Termination Fee”). Endwave acknowledges that the agreements contained in this Section 8.03(b) are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, GigOptix would not enter into this Agreement; accordingly, if Endwave fails to pay in a timely manner the amounts due pursuant to this Section 8.03(b) , and, in order to obtain such payment, GigOptix makes a claim that results in a judgment against Endwave for the amounts set forth in this Section 8.03(b), Endwave shall pay to GigOptix its reasonable costs and expenses (including reasonable attorneys’ fees and expenses) in connection with such suit, together with interest on the amounts set forth in this Section 8.03(b) at the prime rate of interest that under current practice is listed as such under the heading “Money Rates” in the Eastern Edition of The Wall Street Journal on the date such payment was required to be made. Payment of the fees described in this Section 8.03(b) shall be credited toward any damages payable by Endwave in the event of breach of this Agreement.

Section 9.01 Amendment and Modification. Subject to Applicable Law, this Agreement may be amended, modified or supplemented only by written agreement of GigOptix, Merger Sub and Endwave at any time prior to the Effective Time; provided, however, that after approval of this Agreement by the Endwave Stockholders, no such amendment or modification shall change the amount or form of the consideration to be received by the Endwave Stockholders in the Merger.

Section 9.02 Waiver of Compliance; Consents. Any failure of GigOptix or Merger Sub, on the one hand, or Endwave, on the other hand, to comply with any obligation, covenant, agreement or condition herein may be waived by Endwave (with respect to any failure by GigOptix or Merger Sub) or GigOptix and Merger Sub (with respect to any failure by Endwave), respectively, only by a written instrument signed by the party granting such waiver, but such waiver or failure to insist upon strict compliance with such obligation, covenant, agreement or

condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure. Whenever this Agreement requires or permits consent by or on behalf of any party hereto, such consent shall be given in writing in a manner consistent with the requirements for a waiver of compliance as set forth in this Section 9.02.

Section 9.03 Survival; Investigations. The respective representations and warranties of GigOptix, Merger Sub and Endwave contained herein or in any certificates or other documents delivered prior to or at the Closing shall not be deemed waived or otherwise affected by any investigation made by any party hereto and shall not survive the Effective Time.

IN WITNESS WHEREOF, GigOptix, Merger Sub and Endwave have caused this Agreement to be signed by their respective duly authorized officers as of the date first above written.

Endwave Corporation, a Delaware corporation (“Endwave”), does hereby certify to the following facts relating to the merger (the “Merger”) of Aerie Acquisition Corporation, a Delaware corporation (the “Company”), with and into Endwave with Endwave continuing as the surviving corporation of the Merger (the “Surviving Corporation”):

FOURTH: The Certificate of Incorporation of the Surviving Corporation shall be superseded and replaced in its entirety with the Amended and Restated Certificate of Incorporation attached hereto as Exhibit A.

FIFTH: The executed Agreement of Merger is on file at an office of the Surviving Corporation located at 2300 Geng Road, Suite 250, Palo Alto, CA 94303, Attention: Chief Executive Officer

SEVENTH: The Merger shall become effective immediately upon the filing of this Certificate of Merger with the Secretary of State of the State of Delaware.

IN WITNESS WHEREOF, Endwave has caused this Certificate of Merger to be executed by its duly authorized officer, as of [ ], 2011.

The address of the Corporation’s registered office in the State of Delaware is National Corporate Research, Ltd., 615 South DuPont Highway, in the city of Dover, County of Kent, Delaware, 19901. The name of its registered agent at such address is National Corporate Research, Ltd.

The purpose of the Corporation is to engage in any lawful act or activity for which corporations may be organized under the Delaware General Corporation Law.

The aggregate number of shares which the Corporation shall have authority to issue is One Thousand (1,000) shares of capital stock all of which shall be designated “Common Stock” and have a par value of $0.0001 per share. The number of authorized shares of Common Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of shares of stock of the Corporation representing a majority of the votes represented by all outstanding shares of stock of the Corporation entitled to vote, irrespective of the provisions of Section 242(b)(2) of the Delaware General Corporation Law.

In furtherance of and not in limitation of the powers conferred by the laws of the State of Delaware, the Board of Directors of the Corporation is expressly authorized to make, amend or repeal Bylaws of the Corporation.

The business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors. Elections of directors need not be by written ballot unless otherwise provided in the Bylaws of the Corporation.

(A) To the fullest extent permitted by the Delaware General Corporation Law (the “DGCL”), as the same may be amended from time to time, or by any other applicable state law, a director of the Corporation shall not be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a

director. If the DGCL or other applicable state law is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of the Corporation shall be eliminated or limited to the fullest extent permitted by the DGCL or such other applicable state law, as so amended.

(B) To the fullest extent permitted by applicable law, the Corporation is also authorized to provide indemnification of (and advancement of expenses to) such directors and officers (and any other persons to which Delaware or other applicable state law permits the Corporation to provide indemnification) through Bylaw provisions, agreements with such agents or other persons, vote of stockholders or disinterested directors or otherwise, in excess of the indemnification and advancement otherwise permitted by Section 145 of the DGCL or other applicable state law, subject only to limits created by applicable Delaware or other state law (statutory or non-statutory), with respect to actions for breach of duty to a corporation, its stockholders, and others.

(C) Any repeal or modification of the foregoing provisions of this Article VII shall not adversely affect any right or protection of a director or officer of the Corporation, or other person indemnified by the Corporation, with respect to any acts or omissions of such director, officer or other person existing at the time of such repeal or modification.

You have asked Merriman Capital, Inc. (“Merriman”) to advise the Board of Directors of Endwave Corporation (“Endwave”) with respect to the fairness, from a financial point of view, to the holders of common stock, par value $0.001 per share, of Endwave of the Stock Merger Consideration set forth in the Agreement and Plan of Merger, dated as of February 4, 2011 (the “Agreement”) by and among Endwave, GigOptix, Inc. (“GigOptix”), and Aerie Acquisition Corporation, a wholly owned subsidiary of GigOptix (“Merger Sub”). All capitalized terms used and not otherwise defined herein have the respective meanings assigned to such terms in the Agreement. The terms and conditions of the Merger are more fully set forth in the Merger Agreement.

In our review and analysis and in arriving at our opinion, we have relied upon, without any independent verification or liability therefor, the accuracy and completeness of all of the financial and other information that was publicly available or supplied or otherwise made available to us by or on behalf of Endwave, and upon the assurances of the management of Endwave that no relevant information has been omitted or remains undisclosed to us. We have also relied upon the management of Endwave as to the reasonableness of the assumptions, and bases therefor, of the financial and operating projections provided to us. We also have held discussions with

members of the management of Endwave regarding their views with respect to a number of risks and uncertainties associated with projections provided to us. We have not been engaged to assess the reasonableness of such projections, of the timeframe for achieving them or of the assumptions on which they were based. We express no view as to such projections or assumptions. We have not conducted a discounted cash flow analysis due to the lack of predictability of future cash flows. We have assumed that they have been reasonably prepared based on assumptions reflecting the best current available estimates and judgments by managements of Endwave and GigOptix as to the expected future results of operations and financial condition of Endwave and GigOptix to which such analyses or forecasts relate.

In addition, we have not evaluated or appraised any of the assets, properties or facilities of Endwave or GigOptix nor have we been furnished with any such evaluation or appraisal. We have also not been requested to assume, and have not assumed, any obligation to conduct any inspection of the properties or facilities of Endwave or to evaluate any assets or liabilities, including any litigation, nor were we furnished with any such evaluation. We have not evaluated the solvency of Endwave or the fair value of Endwave under any state or federal laws relating to bankruptcy, insolvency or similar matters.

We do not offer any opinion as to the material terms of the Agreement or the form of the Merger. We have assumed, with your consent, that the Merger will be consummated as promptly as practicable, with no unanticipated delays in the consummation of the Merger. We have also assumed, with your consent, that the final executed form of the Agreement will not differ in any material respect from the form of the Draft Agreement furnished to and reviewed by us, and that the final forms of all agreements, instruments and certificates relating to the Merger will not differ in any material respect from the forms thereof furnished to and reviewed by us.

Without limiting the generality of the foregoing, for purposes of rendering our opinion, we have assumed, in all respects material to our analysis, with your consent, (a) that the proposed Merger will be consummated as described in the Agreement and in compliance with all applicable laws, (b) that all of the representations and warranties of each party contained in the Agreement are true, correct and complete and do not omit to state any material fact required to be stated or incorporated by reference therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading, (c) that each party to the Agreement will perform all of the covenants and agreements required to be performed by it thereunder without any consents or waivers of the other parties thereto, and (d) that all conditions to the consummation of the proposed Merger will be satisfied without waiver thereof. We note that we are not legal, tax, accounting or regulatory experts, and have made no independent investigation of any legal matters involving Endwave or the Merger, and we have assumed the correctness of all statements with respect to legal matters made or otherwise provided to you and us by Endwave’s counsel. We do not express any opinion as to any legal, tax, accounting or regulatory matters involving Endwave or the Merger, as to which we understand that Endwave has conducted such investigations, and has obtained such advice from qualified professionals, as it has deemed necessary. We have assumed, with your consent, that all governmental, regulatory or other consents and approvals (contractual or otherwise) necessary for, or in connection with, the consummation of the proposed Merger will be obtained without any adverse effect on Endwave on the contemplated benefits of the proposed Merger to Endwave, in any respect material to our analysis.

This opinion is necessarily based on the economic, monetary, market and other conditions as in effect on, and the information made available to us, as of the date hereof and does not address any matters subsequent to such date. Although subsequent developments may affect this opinion, we do not have any obligation to update, revise or reaffirm our opinion after the date hereof. We disclaim any undertaking or obligation to advise any person of any change in any fact or matter affecting the opinion which may come or be brought to our attention after the date hereof. Without limiting the foregoing, in the event that in our judgment there is any material change in any fact, assumption upon which our opinion is based or matter affecting the opinion after the date hereof, we reserve the right to withdraw, revise or modify our opinion.

Our opinion is limited to the fairness of the Stock Merger Consideration, from a financial point of view, to the holders of the common stock of Endwave. This opinion does not address the underlying or relative merits of

the Merger or any related transaction and any other transactions or business strategies discussed by the Board of Directors of Endwave or that might be available as alternatives to the Merger, or the decision of Endwave to proceed with the Merger or any related transaction. Our opinion is not, and should not be construed as, a valuation of Endwave or its assets or any class or series of securities of Endwave.

We will receive a fee for our services in rendering this opinion, and we will receive a fee contingent on the consummation of the Merger. In addition, Endwave has agreed to indemnify us for, and exculpate us from, certain liabilities arising out of our engagement. We and our affiliates have not provided investment banking services to Endwave in the past. Neither we nor our affiliates currently make a market in Endwave’s common stock nor do we or our affiliates provide research on Endwave. From October 27. 2004 to June 19, 2009 Merriman made a market in the common stock of Endwave. Merriman’s lead investment banker under this engagement between Merriman and Endwave was employed by Endwave in the capacity of Chief Financial Officer from March 1, 2006 to June 26, 2009. We are a full service securities firm engaged in securities trading and brokerage activities, as well as providing investment banking and other financial services. In the ordinary course of business, we and our affiliates may acquire, hold or sell securities of Endwave or GigOptix.

This opinion has been prepared for the information of the Board of Directors of Endwave for its confidential use in connection with its consideration of the proposed Merger and may not, in whole or in part, be reproduced, disseminated, quoted, summarized, described or referred to at any time, communicated or provided to any person or otherwise made public or used for any other purpose without our prior written consent. In rendering this opinion, we express no view or opinion with respect to the fairness (financial or otherwise) of the amount or nature or any other aspect of any compensation payable to or to be received by any officers, directors, or employees of Endwave or any parties to the Merger, or any class of such persons, relative to the Stock Merger Consideration or otherwise. Our opinion has been authorized for issuance by a fairness committee of Merriman Capital, Inc.

We are not expressing any opinion herein as to the prices at which any securities of Endwave or GigOptix will trade following the announcement or consummation of the Merger.

Based upon and subject to the foregoing and such other matters as we consider relevant, it is our opinion that, as of the date hereof, the proposed Stock Merger Consideration is fair, from a financial point of view, to the holders of Endwave common stock.

Roth Capital Partners, LLC (“Roth”) understands that GigOptix, Inc. (“GGOX”) and its wholly owned subsidiary Aerie Acquisition Corporation (“GGOX Sub”) (collectively, the “Purchaser”) and Endwave Corporation (“ENWV” or the “Seller”), intend to enter into a transaction (the “Transaction”) pursuant to an Agreement and Plan of Merger (the “Agreement”) whereby:

You have asked us to render our opinion with respect to the fairness, from a financial point of view, of the Merger Consideration to the holders of Common Stock, par value $0.001 per share, of GGOX.

In connection with our review of the Transaction, and in arriving at our opinion, we have:

We have also considered such other information, financial studies, analyses and investigations, and financial, economic and market criteria which we deemed relevant.

In conducting our review and arriving at our opinion, with your consent, we have not independently verified any of the foregoing information and we have assumed and relied upon such information being accurate and complete in all material respects, and we have further relied upon the assurances of management of GGOX that they are not aware of any facts that would make any of the information reviewed by us inaccurate, incomplete or misleading in any material respect. With respect to the Transaction Forecast, we have assumed, at the direction of GGOX management, that they have been reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of the management as to the future financial performance of ENWV. We have not been engaged to assess the achievability of any projections or the assumptions on which they were based, and we express no view as to such projections or assumptions. In addition, we have not assumed any responsibility for any independent valuation or appraisal of the assets or liabilities, including any ongoing litigation and administrative investigations, of ENWV or GGOX, nor have we been furnished with any such valuation or appraisal, nor have we evaluated the solvency of ENWV or GGOX under any state or federal law relating to bankruptcy, insolvency or similar matters. We express no opinion regarding the liquidation value of ENWV or GGOX or any other entity. Without limiting the generality of the foregoing, we have undertaken no independent analysis of any pending or threatened litigation, regulatory action, possible unasserted claims or other contingent liabilities, to which GGOX or ENWV or any of their affiliates is a party or may be subject, and at the direction of GGOX and with its consent, our opinion makes no assumption concerning, and therefore does not consider, the possible assertion of claims, outcomes or damages arising out of any such matters. In addition, we have not assumed any obligation to conduct, nor have we conducted any physical inspection of the properties or facilities of ENWV or GGOX.

We also have assumed, with your consent, that the Transactions will be consummated in accordance with the terms set forth in the Agreement and in compliance with the applicable provisions of the Securities Act of 1933, as amended (the “Securities Act”), the Securities Exchange Act of 1934, as amended, and all other applicable federal, state and local statutes, rules, regulations and ordinances, that such Agreement are enforceable against each of parties thereto in accordance with their respective terms, that the representations and warranties of each party in the Agreement are true and correct, that each party will perform on a timely basis all covenants and agreements required to be performed by it under such agreements and that all conditions to the consummation of the Transaction will be satisfied without waiver thereof. Additionally, we have assumed that all the necessary regulatory approvals and consents required for the Transaction will be obtained in a manner that will not adversely affect GGOX or the contemplated benefits of the Transaction. We have further assumed that the Agreement when signed will conform to the last drafts of the Agreement provided to us in all respects material to our analysis, and that the Transaction will be consummated in all material respects as described in the last drafts of the agreements reviewed by us. We have also assumed that all governmental, regulatory and other consents and approvals contemplated by the Agreement will be obtained and that, in the course of obtaining any of those consents and approvals, no modification, delay, limitation, restriction or condition will be imposed or waivers made that would have an adverse effect on GGOX on the contemplated benefits of the Transactions.

Our opinion addresses only the fairness, from a financial point of view, to holders of GGOX Common Stock of the Merger Consideration, and our opinion does not in any manner address any other aspect or implication of the Transaction or any agreement, arrangement or understanding entered into in connection with the Transaction or otherwise, including, without limitation, the fairness of the amount or nature of, or any other aspect relating to, any compensation to any officers, directors or employees of any party to the Transactions, or class of such persons. Our opinion also does not address the relative merits of the Transactions as compared to any alternative business strategies that might exist for GGOX, or the underlying business decision of GGOX to proceed with the Transaction. The issuance of this opinion was not approved by an internal committee. Our opinion is necessarily based on economic, market and other conditions as they exist and can be evaluated on, and the information made available to us on, the date hereof. We express no opinion as to the underlying valuation, future performance or long-term viability of GGOX. Further, we express no opinion as to the prices at which shares of GGOX Common

Stock will trade at any time in the future. It should be understood that, although subsequent developments may affect our opinion, we do not have any obligation to update, revise or reaffirm our opinion and we expressly disclaim any responsibility to do so.

We have acted as financial advisor to GGOX in connection with the Transaction and will became entitled to receive an opinion fee upon the rendering of this opinion. The opinion fee is not contingent upon the consummation of the Transaction. GGOX has agreed to indemnify us for certain liabilities and other items arising out our engagement and reimburse us for certain expenses in connection with our services.

Roth, as part of its investment banking business, is continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes. We and our affiliates have in the past provided, are currently providing and may in the future provide investment banking and other financial services to GGOX for which we and our affiliates have received and would expect to receive compensation. We may also, in the future, provide investment banking and financial advisory services to GGOX, other parties to the Transaction or entities that are affiliated with GGOX or other parties to the Transaction, for which we would expect to receive compensation. We are a full service securities firm engaged in securities trading and brokerage activities, as well as providing investment banking and other financial services. In the ordinary course of business, we and our affiliates may acquire, hold or sell, for our and our affiliates’ own accounts and for the accounts of customers, equity, debt and other securities and financial instruments (including bank loans and other obligations) of GGOX and the other parties to the Transaction, and, accordingly, may at any time hold a long or a short position in such securities.

It is understood that our analysis and this letter were prepared for the benefit, information and use of the Board of Directors of GGOX in connection with its evaluation of the Transaction and were directed only to the fairness to the holders of GGOX common stock, from a financial point of view, of the Merger Consideration. This opinion does not constitute an opinion as to the merits of the Transaction, nor a recommendation to any stockholder as to how such stockholder should vote or act on any matter relating to the Transaction. This opinion may not be used for any other purpose or reproduced, disseminated, quoted or referred to at any time, in any manner or for any purpose without our prior written consent. In furnishing this opinion, we do not admit that we are experts within the meaning of the term “experts” as used in the Securities Act and the rules and regulations thereunder, nor do we admit that this opinion constitutes a report or valuation within the meaning of Section 11 of the Securities Act.

On the basis of and subject to the foregoing, and such other factors as we deemed relevant, we are of the opinion as of the date hereof that the Merger Consideration is fair to the holders of GGOX Common Stock, from a financial point of view.

(a) Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to § 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder’s shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word “stockholder” means a holder of record of stock in a corporation; the words “stock” and “share” mean and include what is ordinarily meant by those words; and the words “depository receipt” mean a receipt or other instrument issued by a depository representing an interest in 1or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository.

(b) Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to § 251 (other than a merger effected pursuant to § 251(g) of this title), § 252, § 254, § 255, § 256, § 257, § 258, § 263 or § 264 of this title:

(1) Provided, however, that no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of the meeting of stockholders to act upon the agreement of merger or consolidation, were either (i) listed on a national securities exchange or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in § 251(f) of this title.

(2) Notwithstanding paragraph (1) of this subsection, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to §§ 251, 252, 254, 255, 256, 257, 258, 263 and 264 of this title to accept for such stock anything except:

a. Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof;

b. Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or held of record by more than 2,000 holders;

c. Cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a. and b. of this paragraph; or

d. Any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a., b. and c. of this paragraph.

(3) In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under § 253 or § 267 of this title is not owned by the parent immediately prior to the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation.

(c) Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all

or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as is practicable.

(1) If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for notice of such meeting (or such members who received notice in accordance with § 255(c) of this title) with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) of this section that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section and, if 1 of the constituent corporations is a nonstock corporation, a copy of § 114 of this title. Each stockholder electing to demand the appraisal of such stockholder’s shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of such stockholder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder’s shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or

(2) If the merger or consolidation was approved pursuant to § 228, § 253, or § 267 of this title, then either a constituent corporation before the effective date of the merger or consolidation or the surviving or resulting corporation within 10 days thereafter shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of this section and, if 1 of the constituent corporations is a nonstock corporation, a copy of § 114 of this title. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice, demand in writing from the surviving or resulting corporation the appraisal of such holder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder’s shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder’s shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given.

(e) Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) of this section hereof and who is

otherwise entitled to appraisal rights, may commence an appraisal proceeding by filing a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party shall have the right to withdraw such stockholder’s demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) of this section hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder’s written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) of this section hereof, whichever is later. Notwithstanding subsection (a) of this section, a person who is the beneficial owner of shares of such stock held either in a voting trust or by a nominee on behalf of such person may, in such person’s own name, file a petition or request from the corporation the statement described in this subsection.

(f) Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation.

(g) At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder.

(h) After the Court determines the stockholders entitled to an appraisal, the appraisal proceeding shall be conducted in accordance with the rules of the Court of Chancery, including any rules specifically governing appraisal proceedings. Through such proceeding the Court shall determine the fair value of the shares exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. Unless the Court in its discretion determines otherwise for good cause shown, interest from the effective date of the merger through the date of payment of the judgment shall be compounded quarterly and shall accrue at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the merger and the date of payment of the judgment. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, proceed to trial upon the appraisal prior to the final determination of the stockholders entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder’s certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section.

(i) The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court’s decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state.

(j) The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney’s fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal.

(k) From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder’s demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just; provided, however that this provision shall not affect the right of any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party to withdraw such stockholder’s demand for appraisal and to accept the terms offered upon the merger or consolidation within 60 days after the effective date of the merger or consolidation, as set forth in subsection (e) of this section.

(l) The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation.
