PROXY STATEMENT
FOR THE
HITTITE MICROWAVE CORPORATION
2013 ANNUAL MEETING OF STOCKHOLDERS

IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS FOR THE
STOCKHOLDER MEETING TO BE HELD ON MAY 15, 2013

This proxy statement and our 2012 Annual Report to Stockholders are also available for viewing, printing and downloading at http://materials.proxyvote.com/43365Y.

The 2013 Annual Meeting of Stockholders of Hittite Microwave Corporation will be held at 10:00 a.m., local time, on Wednesday, May 15, 2013 at the offices of Foley Hoag LLP, Suite 4000, North Entrance, Bay Colony Corporate Center, 1000 Winter Street, Waltham, Massachusetts 02451. At the meeting, stockholders of record on the record date for the meeting who are present or represented by proxy will have the opportunity to vote on the following matters:

We have sent you this proxy statement and the enclosed proxy card because our board of directors is soliciting your proxy to vote at the meeting (including any adjournment or postponement of the meeting).

We will pay the cost of soliciting proxies. Our directors, officers and employees may solicit proxies in person, by telephone or by other means. We will reimburse brokers and other nominee holders of shares for expenses they incur in forwarding proxy materials to the beneficial owners of those shares. We do not plan to retain the services of a proxy solicitation firm to assist us in this solicitation.

We will mail this proxy statement and the enclosed proxy card to stockholders for the first time on or about April 12, 2013. In this mailing, we will include a copy of our 2012 Annual Report to Stockholders, which includes our Annual Report on Form 10-K for the year ended December 31, 2012 (excluding exhibits), as filed with the Securities and Exchange Commission.

Holders of record of our common stock at the close of business on March 27, 2013 are entitled to one vote per share of common stock on each proposal properly brought before the annual meeting.

A list of stockholders entitled to vote will be available at the annual meeting. In addition, you may contact our Chief Financial Officer, William W. Boecke, at our offices located at 2 Elizabeth Drive, Chelmsford, Massachusetts 01824, to make arrangements to review a copy of the stockholder list at

those offices, between the hours of 9:00 a.m. and 5:30 p.m., local time, on any business day from May 1, 2013 to the time of the annual meeting.

You are entitled to one vote at the meeting for each share of common stock registered in your name at the close of business on March 27, 2013, the record date for the meeting. You may vote your shares at the meeting in person, by proxy or via the internet.

If you vote by proxy or via the internet or telephone, you may change or revoke your vote at any time before it is exercised by taking one of the following actions:

If the shares you own are held in "street name" by a brokerage firm, your brokerage firm, as the record holder of your shares, is required to vote your shares according to your instructions. In order to vote your shares, you will need to follow the directions your brokerage firm provides you. Many brokers also offer the option of providing voting instructions to them over the internet or by telephone, directions for which would be provided by your brokerage firm on your vote instruction form.

Under stock exchange rules applicable to most brokerage firms, if you do not give instructions to your broker, it is permitted to vote any shares it holds for your account in its discretion with respect to "routine" proposals, but it is not allowed to vote your shares with respect to certain non-routine proposals. Proposals 1 and 2, regarding the election of directors and the advisory say on pay vote, are "non-routine" proposals. If you do not instruct your broker how to vote with respect to these proposals, your broker will not vote with respect to these proposals and your shares will be recorded

as "broker non-votes" and will not affect the outcome of the vote on these proposals. "Broker non-votes" are shares that are held in "street name" by a bank or brokerage firm that indicates on its proxy that, while voting in its discretion on one matter, it does not have or did not exercise discretionary authority to vote on another matter.

Proposal 3, the ratification of PricewaterhouseCoopers LLP as our independent registered public accounting firm, is considered to be a routine item under the applicable rules and your broker will be able to vote on that item even if it does not receive instructions from you, so long as it holds your shares in its name.

If a broker or nominee holds shares of our common stock in "street name" for your account, then this proxy statement may have been forwarded to you with a voting instruction card, which allows you to instruct the broker or nominee how to vote your shares on the proposals described herein. To vote by proxy or instruct your broker how to vote, you should follow the directions provided with the voting instruction card. In order to have your vote counted on Proposals 1 and 2, you must either provide timely voting instructions to your broker or obtain a properly executed proxy from the broker or other record holder of the shares that authorizes you to act on behalf of the record holder with respect to the shares held for your account.

At the close of business on April 1, 2013, 31,574,455 shares of common stock were outstanding. Our by-laws require that a majority of the outstanding shares of our common stock be represented, in person or by proxy, at the meeting in order to constitute the quorum we need to transact business at the meeting. We will count abstentions and broker non-votes as shares represented at the meeting in determining whether a quorum exists.

If you and other residents at your mailing address own shares of common stock through a broker or other nominee, you may have elected to receive only one copy of this proxy statement and our 2012 Annual Report. If you and other residents at your mailing address own shares of common stock in your own names, you may have received only one copy of this proxy statement and our 2012 Annual Report unless you provided our transfer agent with contrary instructions.

This practice, known as "householding," is designed to reduce our printing and postage costs. You may promptly obtain an additional copy of this proxy statement, enclosed proxy card and our 2012 Annual Report by sending a written request to Hittite Microwave Corporation, attention William W. Boecke, Chief Financial Officer, 2 Elizabeth Drive, Chelmsford, Massachusetts 01824, or by calling Mr. Boecke at (978) 250-3343. If you hold your shares through a broker or other nominee and wish to discontinue householding or to change your householding election, you may do so by contacting your broker or by calling (800) 542-1061 or writing to Broadridge Financial Solutions, 51 Mercedes Way, Edgewood, NY 11717. If you hold shares in your own name and wish to discontinue householding or change your householding election, you may do so by calling (800) 937-5449 or writing to American Stock Transfer & Trust Company, 6201 15^th Avenue, Brooklyn, NY 11219.

The first proposal on the agenda for the meeting is the election of six persons to serve as directors. The term of each director elected at our 2013 Annual Meeting of stockholders will begin at the meeting and end at our 2014 annual meeting of stockholders, or, if later, when the director's successor has been elected and has qualified.

The following table sets forth certain information as of April 12, 2013 regarding our incumbent directors who have been nominated for re-election. Stephen G. Daly, who had been our President and Chief Executive Officer and a member of our board of directors since 2004 and our Chairman since 2005, stepped down from those offices on April 1, 2013 pursuant to a previously announced succession plan, and is not standing for re-election as a director. Our Board of Directors appointed Rick D. Hess to succeed Mr. Daly as President and Chief Executive Officer and elected Franklin Weigold to succeed him as Chairman of the Board, effective April 1, 2013.

Ernest L. Godshalk has served as a member of our board of directors since 2008. From 2001 until his retirement in 2004, Mr. Godshalk served as President, Chief Operating Officer and a director of Varian Semiconductor Equipment Associates, Inc., a manufacturer of semiconductor processing equipment. Previously, he served as Varian's Vice President and Chief Financial Officer. He is a director of GT Advanced Technologies, Inc. He is also a Board Leadership Fellow of the National Association of Corporate Directors. Mr. Godshalk received his B.A. from Yale University in 1967 and his M.B.A. from Harvard University in 1969. We believe that Mr. Godshalk's educational background in management, accounting and finance, his extensive knowledge of our industry, gained from his employment as a senior operating executive and chief financial officer of public companies engaged in businesses similar to ours, and his experience as a director of other public companies qualify him to serve as a member of our board of directors.

advanced photovoltaic cells on flexible plastic. From 2004 to 2006, Mr. Hess was president and chief executive officer of Integrated Fuel Cell Technologies, Inc., a developer of fuel cell systems. From 1989 to 2004, Mr. Hess held several positions at M/A-COM, including president from 1999 to 2004. M/A-COM was a semiconductor provider of high frequency components and systems for the wireless, defense, public safety and automotive markets. Mr. Hess had previously founded Stable Energy Sources, a manufacturer of microwave subsystems and components serving military and industrial markets. He began his career as an engineer at Westinghouse Electric. Mr. Hess received a B.S. in Electrical Engineering from Purdue University and an M.S. in Electrical Engineering from Johns Hopkins University. We believe that Mr. Hess's educational background in electrical engineering, his extensive knowledge of our industry, gained from his employment as a senior operating executive of public and private semiconductor companies, and the skills, judgment and experience he has accumulated in these capacities and as a chief executive officer qualify him to serve as a member of our board of directors.

Adrienne M. Markham has served as a member of our board of directors since 2008. Ms. Markham has been a director at the law firm of Goulston & Storrs, a Professional Corporation since 1991. Ms. Markham has over 27 years of experience focusing on employment and corporate litigation. She has been an advisor to several bio-science and bio-tech firms. Ms. Markham received a B.S. in Education from Boston University and a J.D. from Suffolk University Law School. We believe that Ms. Markham's educational background and professional training as an attorney, her knowledge and experience in the fields of litigation and employment law and her work as an advisor to other technology-based businesses qualify her to serve as a member of our board of directors.

Brian P. McAloon has served as a member of our board of directors since 2008. Mr. McAloon was, from 2001 to 2008, Group Vice President of the DSP and Systems Products Group of Analog Devices, Inc., a provider of semiconductors for high performance signal processing applications. He also served in a number of other roles at Analog Devices, including Vice President, Sales, Vice President, Sales and Marketing—Europe and Southeast Asia and General Manager, Analog Devices, B.V. Mr. McAloon received his B.Sc. in Electronics and Electrical Engineering from Glasgow University. We believe that Mr. McAloon's educational background in electrical engineering, his extensive knowledge of our industry, and the skills, knowledge and judgment accumulated through his long tenure as a senior operating and sales executive of a public company that is engaged in a business similar to ours qualify him to serve as a member of our board of directors.

Cosmo S. Trapani has served as a member of our board of directors since 2000. From 2000 to 2002, Mr. Trapani served as Vice President and Chief Financial Officer of PRI Automation, Inc, a manufacturer of semiconductor process automation systems. From 1999 to 2000, Mr. Trapani was Senior Vice President and Chief Financial Officer at Circor International, Inc., a manufacturer of fluid control systems. From 1990 to 1998, Mr. Trapani was Executive Vice President and Chief Financial Officer of Unitrode Corporation, a manufacturer of analog and mixed-signal integrated circuits. Prior to Unitrode, Mr. Trapani was Vice President Finance for Instron Corporation, a testing products company, and Corporate Controller and General Manager of Computervision CAD/CAM Division, an integrated computer systems company. Mr. Trapani was a member of the board of directors and chairman of the audit committee of Ibis Technology, a manufacturer of equipment for the semiconductor industry, until its dissolution in February 2009. Mr. Trapani is a Certified Public Accountant and has been a member of various societies including AICPA, Massachusetts Society of CPAs, Board of Directors of Massachusetts Society of CPAs, and Chapter President of IMA. Mr. Trapani received a B.S. from Boston College and was a Commanding Officer in the U.S. Army. We believe that Mr. Trapani's educational background in accounting and finance, his professional experience and certification as a public accountant, his knowledge of the semiconductor, semiconductor equipment, and other technology-based industries and the skills, knowledge and judgment accumulated through his service as a chief financial officer of a number of public companies qualify him to serve as a member of our board of directors.

Franklin Weigold was elected Chairman of the Board on April 1, 2013. He has served as a member of our board of directors since 2003 and as our lead director since 2009. From 1999 to 2003, Mr. Weigold served as Vice President and General Manager of the Micromachined Products Division of Analog Devices, Inc., and from 1992 to 1999 was Vice President and General Manager of its Transportation and Industrial Products Division. Prior to joining Analog Devices, Mr. Weigold served as President and Chief Operating Officer of Unitrode Corporation. Previously, he was President of Silicon General Inc. Mr. Weigold also serves on the board of directors of privately held Enpirion, Inc. Mr. Weigold received a B.S. in Electrical Engineering from Michigan Technological University and an M.B.A. from the University of Pittsburgh. We believe that Mr. Weigold's educational background in electrical engineering and his extensive knowledge of our industry, gained from his employment as a senior operating executive of public and private semiconductor companies engaged in businesses similar to ours, qualify him to serve as a member of our board of directors.

If for any reason any of the nominees becomes unavailable for election, the persons designated in the proxy card may vote the shares represented by proxy for the election of a substitute nominated by the board of directors. Each nominee has consented to serve as a director if elected, and we currently have no reason to believe that any of them will be unable to serve.

The six nominees receiving the greatest numbers of votes cast will be elected as directors. Brokers may not vote shares they hold for you in the election of directors, unless they receive timely voting instructions from you. We will not count votes withheld or broker non-votes as having been cast for the election of a director.

OUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THE RE-ELECTION OF MS. MARKHAM AND MESSRS. GODSHALK, HESS, McALOON, TRAPANI AND WEIGOLD AS DIRECTORS.

Each year, we provide our stockholders with the opportunity to vote, on a nonbinding, advisory basis, whether to approve the compensation of our named executive officers as disclosed in our annual proxy statement. This "say on pay" vote does not address any specific element of compensation or any particular year; rather, the vote relates to the compensation of our named executive officers in its totality, as described in this proxy statement under the heading "Executive Compensation," including in the Compensation Discussion and Analysis section on pages 24 to 29, the executive compensation tables on pages 17 to 24, and the accompanying narrative disclosures.

The say on pay vote is advisory, and the outcome of this proposal is not binding on us. However, our compensation committee values the opinions of our stockholders and will carefully consider the outcome of the vote when making future compensation decisions for our executive officers.

As you consider how to vote on this Proposal 2, here are some key points about our company and our executive compensation that we hope you will keep in mind:

Under the leadership of our executive team, our revenue has grown in each year since 2009. We have continued to execute our strategy of introducing innovative, high performance products that are valued by our customers for their ability to address technically challenging applications: in the period 2010 through 2012, we introduced 258 new standard products, and added 12 new product lines to our product offerings.

As a result, during the three years ended December 31, 2012, our revenues have grown from $163.0 million in 2009 to $264.4 million in 2012, and our net income per diluted share has increased from $1.55 in 2009 to $2.22 in 2012. Even during challenging periods in the semiconductor industry,

such as in 2009 when our revenues declined year-over-year for the only time in our history and in 2012 when our revenue growth slowed significantly, we have been able, through careful expense management, to maintain our strong record of profitability. Our gross margin has exceeded 73% and our operating margin has exceeded 40% in each of the last three years.

Over the three-year period covered by the compensation disclosures in this proxy statement, our stock price increased from approximately $41 to approximately $62, for a total stockholder return of 52%. See "Comparison of 5 Year Cumulative Total Return" in our 2012 Annual Report to Stockholders, which accompanies this proxy statement.

We do not use a formula to allocate total compensation among these various components. Each of the elements of our executive compensation program is essential to meeting the program's overall objectives, and most of the compensation components simultaneously fulfill one or more of these objectives.

For this reason, long-term equity-based incentive compensation has historically been the largest component of our executive officers' compensation. We believe that equity-based incentive awards motivate and reward value creation, as their benefit to the executive increases as our stock price increases. They also serve as effective retention tools due to their time-based vesting, thus increasing our ability to retain our executive officers.

We believe our executive compensation program has appropriately aligned executive pay with company performance and encouraged and rewarded behavior by our executives that is in the best interest of our company and our stockholders. Our executives receive no perquisites other than those we make available to our senior management employees generally; they have no agreements for fixed terms of employment or for payment of severance upon termination of employment or upon a change in control; and they are not guaranteed salary increases, bonuses or complex retirement benefits.

Our compensation committee has reviewed our incentive compensation programs and believes, particularly in light of the discretionary, retrospective nature of our short-term incentive program, that our compensation program has not encouraged or rewarded excessive or inappropriate risk taking.

We further believe, and hope that you will agree, that the compensation of our named executive officers during the three-year period covered by the compensation disclosures in this proxy statement is appropriate in light of our company's financial performance over this period.

We therefore ask our stockholders to adopt the following resolution at the annual meeting:

In order to pass, this proposal must receive a majority of the votes cast with respect to this matter. Brokers may not vote shares they hold for you with respect to this proposal unless they receive timely voting instructions from you. We will not count abstentions or broker non-votes as votes cast.

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR APPROVAL OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS AS DISCLOSED IN THIS PROXY STATEMENT.

PROPOSAL 3: RATIFICATION OF APPOINTMENT OF INDEPENDENT
REGISTERED PUBLIC ACCOUNTING FIRM

PricewaterhouseCoopers LLP currently serves as our independent registered public accounting firm and audited our consolidated financial statements and our internal control over financial reporting for the year ended December 31, 2012. Our audit committee has appointed PricewaterhouseCoopers LLP to serve as our independent registered public accounting firm for 2013, and to conduct audits of our consolidated financial statements and of our internal control over financial reporting, for the year ending December 31, 2013.

Our audit committee is responsible for selecting and appointing our independent registered public accounting firm, and this appointment is not required to be ratified by our stockholders. However, our audit committee has recommended that the board of directors submit this matter to the stockholders as a matter of good corporate practice. If the stockholders fail to ratify the appointment, the audit committee will reconsider whether to retain PricewaterhouseCoopers LLP, and may retain that firm or another without re-submitting the matter to our stockholders. Even if the appointment is ratified, the audit committee may, in its discretion, direct the appointment of a different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of Hittite and our stockholders.

In order to pass, this proposal must receive a majority of the votes cast with respect to this matter. We will not count abstentions or broker non-votes as votes cast.

OUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THE PROPOSAL TO RATIFY THE APPOINTMENT OF PRICEWATERHOUSECOOPERS LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR 2013.

The members of our board of directors are elected annually at our annual meeting of stockholders. Other than Mr. Hess, each of our nominees for director is independent within the meaning of the applicable rules of the SEC and The Nasdaq Stock Market.

Until recently, Stephen G. Daly, our chief executive officer, also served as the chairman of our board of directors, and an independent, non-employee director, Franklin Weigold, served as our lead director. Rick D. Hess succeeded Mr. Daly as chief executive officer on April 1, 2013, and in conjunction with that transition, Mr. Weigold was named chairman of the board, effective April 1, 2013.

Our chief executive officer is responsible for setting the strategic direction for our company and the day to day leadership and performance of the company, while our chairman, who is not an executive officer, sets the agenda for board meetings, facilitates communications between the board and the chief executive officer and discussion among the independent directors and presides over meetings of the board and stockholders. Our independent directors meet in executive session on a regular basis, without management present, with our chairman presiding.

Our board of directors has adopted Corporate Governance Guidelines which may be found through the Investors page of our website at www.hittite.com.

Our board of directors has established an audit committee, a compensation committee and a nominating and corporate governance committee, which are the only standing committees of the board of directors.

The membership and leadership of our standing committees are reviewed annually by the nominating and corporate governance committee, whose recommendations are acted upon by the full board. Although the board has not adopted a formal policy requiring realignment of committee assignments at fixed intervals, the board believes that periodic rotation of committee memberships and leadership is beneficial, as it broadens the experience and contributions of our directors and brings new perspective to the work of our board committees.

Audit committee. The current members of our audit committee are Mr. Godshalk, who serves as Chairman and Messrs. McAloon and Trapani. Our board of directors has determined that each member of the audit committee is an independent director, and that each of Messrs. Godshalk and Trapani qualifies as an "audit committee financial expert," as defined by applicable rules of the SEC and The Nasdaq Stock Market. The audit committee assists our board of directors in its oversight of:

The audit committee has direct responsibility for the appointment, compensation, retention and oversight of the work of our independent registered public accounting firm. The audit committee establishes and implements policies and procedures for the pre-approval of all audit services and all permissible non-audit services provided by our independent registered public accounting firm. During the year ended December 31, 2012, our audit committee met in person or by telephone eleven times.

You can find a copy of the charter of our audit committee in its current form, as approved by our board of directors, through the Investors page of our website at www.hittite.com.

Compensation committee. The current members of our compensation committee are Ms. Markham, who serves as Chairman and Messrs. Godshalk and Trapani, each of whom is an independent director. The compensation committee:

During the year ended December 31, 2012, our compensation committee met in person or by telephone nine times and acted three times by unanimous written consent. You can find a copy of the charter of our compensation committee in its current form, as approved by our board of directors, through the Investors page of our website at www.hittite.com.

Nominating and corporate governance committee. The current members of our nominating and corporate governance committee are Mr. McAloon, who serves as Chairman, Ms. Markham and Mr. Weigold, each of whom is an independent director. The nominating and corporate governance committee:

During the year ended December 31, 2012, our nominating and corporate governance committee met in person or by telephone five times. You can find a copy of the charter of our nominating and corporate governance committee in its current form, as approved by our board of directors, through the Investors page of our website at www.hittite.com.

Our board as a whole has responsibility for risk oversight, with reviews of certain areas being conducted by the relevant board committees that report on their deliberations to the board. The oversight responsibility of the board and its committees is enabled by management reporting to the board about the identification, assessment and management of critical risks and management's risk mitigation strategies. We believe that our board's ability to discharge its risk oversight is enhanced by the service of our chief executive officer as a director.

The board and its committees oversee risks associated with their respective principal areas of focus, as summarized below.

Board/Committee		Primary Areas of Risk Oversight

Full Board		Strategic, financial and execution risks and exposures associated with the annual operating plan and five-year strategic plan; litigation and regulatory exposures and other current matters that may present material risk to our operations, plans, prospects or reputation; acquisitions and divestitures; operational risk related to our information technology, or IT, systems; and senior management succession planning.
Audit Committee		Risks and exposures associated with financial matters, particularly financial reporting, tax, accounting, disclosure and internal control over financial reporting; risks related to the integrity from a financial reporting point of view of our IT systems; financial policies and investment guidelines; and credit and liquidity matters.
Nominating and Corporate Governance Committee		Risks and exposures relating to our corporate governance; and, in conjunction with the full Board, director and senior management succession planning.
Compensation Committee		Risks and exposures associated with compensation programs and arrangements, including incentive plans.

None of the members of our compensation committee during the year ended December 31, 2012 has ever been employed by us or had any relationship requiring disclosure herein pursuant to Item 404 of Regulation S-K. During 2012, none of our executive officers served as a director or member of the compensation committee (or other board committee performing equivalent functions or, in the absence of any such committee, the entire board of directors) of another entity, one of whose executive officers served on our compensation committee or board of directors.

Our non-employee directors receive equity-based compensation in the form of awards under our 2005 Stock Incentive Plan, and also receive cash fees as follows:

The cash fees described above are paid quarterly in arrears. Non-employee directors are also reimbursed upon request for travel and other out-of-pocket expenses incurred in connection with their attendance at meetings of the board and of committees on which they serve.

Each non-employee director who is first elected to the board, or who is elected to an additional one-year term at any annual meeting of stockholders, receives upon such election a restricted stock award of a number of shares of our common stock, fixed on the date of grant, that has a fair market value on the date of grant equal to $130,000. In addition, effective April 1, 2013, our chairman receives annually, immediately following our annual meeting of stockholders, a restricted stock award of a number of shares of our common stock having a value on the date of grant equal to $25,000. Each such restricted stock award vests on the earlier of the first anniversary of the date of grant or the date of the next annual meeting of stockholders.

The following table provides information concerning the compensation earned by each person, other than Mr. Daly, who served as a member of our board of directors during 2012. See "Executive Compensation" for a discussion of the compensation of Mr. Daly.

Our board of directors met in person or by telephone thirteen times during 2012. No director attended fewer than 75% of the aggregate number of meetings of the board of directors and of any committee of the board on which he or she served in 2012.

Our directors are expected to attend meetings of the board of directors and meetings of committees on which they serve. Our directors are expected to spend the time needed at each meeting and to meet as frequently as necessary to properly discharge their responsibilities. We encourage members of our board of directors to attend annual meetings of stockholders, but we do not have a formal policy requiring them to do so. Each of our directors attended the 2012 annual meeting of stockholders.

Our nominating and corporate governance committee, in consultation with our chairman of the board and chief executive officer, is responsible for identifying and reviewing candidates to fill open positions on the board, including positions arising as a result of the removal, resignation or retirement of any director, an increase in the size of the board or otherwise, and recommending to our full board

candidates for nomination for election to the board. In recommending new directors, the committee will consider any requirements of applicable law or listing standards, a candidate's strength of character, judgment, business experience and specific area of expertise, diversity, factors relating to the composition of the board (including its size and structure), and such other factors as the committee deems to be appropriate. The goal of the committee is to assemble a board that consists of individuals who bring a variety of complementary attributes and who, taken together, have the appropriate skills and experience to oversee our business. The committee is responsible for reviewing from time to time the appropriate skills and characteristics required of board members in the context of the current make-up of the board, including such factors as business experience, diversity, and personal skills in technology, finance, marketing, sales, financial reporting and other areas that contribute to an effective board.

The committee considers diversity, which it views broadly to include diversity of experience, skills and viewpoint as well as traditional diversity concepts such as race and gender, as one of a number of factors in identifying nominees for director. The committee has not adopted any formal policy, guidelines or procedures with respect to the consideration of diversity in the nominating process.

Stockholders may recommend individuals to the nominating and corporate governance committee for consideration as potential director candidates by submitting their names, together with appropriate biographical information and background materials and a statement as to whether the stockholder or group of stockholders making the recommendation has beneficially owned more than 5% of our common stock for at least a year as of the date such recommendation is made, to our nominating and corporate governance committee, c/o Secretary, Hittite Microwave Corporation, 2 Elizabeth Drive, Chelmsford, Massachusetts 01824. Assuming that appropriate biographical and background material has been provided on a timely basis, the nominating and corporate governance committee will evaluate stockholder-recommended candidates by following substantially the same process, and applying substantially the same criteria, as it follows for candidates that it recommends. If the board determines to nominate a stockholder-recommended candidate and recommends his or her election, then his or her name will be included in our proxy card for the next annual meeting. Any recommendation of a potential director nominee should also include a statement signed by the proposed nominee expressing a willingness to serve on our board if elected. As part of this responsibility, the committee will be responsible for conducting, subject to applicable law, any and all inquiries into the background and qualifications of any candidate for the board and such candidate's compliance with the independence and other qualification requirements established by the committee or imposed by applicable law or listing standards.

Stockholders wishing to communicate with our board should send correspondence to the attention of the Chairman of the Board, c/o Hittite Microwave Corporation, 2 Elizabeth Drive, Chelmsford, Massachusetts 01824, and should include with the correspondence evidence that the sender of the communication is one of our stockholders. Satisfactory evidence would include, for example, contemporaneous correspondence from a brokerage firm indicating the identity of the stockholder and the number of shares held. The chairman will review all correspondence confirmed to be from stockholders and decide whether or not to forward the correspondence or a summary of the correspondence to the full board or a committee of the board. The chairman will review all stockholder correspondence, but the decision to relay that correspondence to the full board or a committee will rest entirely within his discretion. Our board believes that this process will suffice to handle the relatively low volume of communications we have historically received from our stockholders. If the volume of communications increases such that this process becomes burdensome to the chairman, our board may elect to adopt more elaborate screening procedures.

We have adopted a code of business conduct and corporate ethics policy that applies to all of our directors and employees, including our chief executive officer, chief financial officer and other executive officers. Our code of ethics includes provisions covering conflicts of interest, business gifts and entertainment, outside activities, compliance with laws and regulations, insider trading practices, antitrust laws, payments to government personnel, bribes or kickbacks, corporate record keeping, accounting records, the reporting of illegal or unethical behavior and the reporting of accounting concerns. Any waiver of any provision of the code of ethics granted to an executive officer or director may only be made by the board of directors. The code of ethics is posted under "Investors—Governance Policies—Code of Business Conduct and Corporate Ethics Policy" on our website at www.hittite.com.

The following table summarizes the compensation earned during the year ended December 31, 2012 by our chief executive officer, our chief financial officer, who is our principal financial officer, and by our three next most highly compensated executive officers who were in office at December 31, 2012, whom we refer to in this proxy statement as our "named executive officers."

The compensation of our executive officers is discussed periodically by the compensation committee of our board of directors throughout the year, and is formally reviewed and acted upon by the committee on an annual basis, in two stages. Prior to year end, salaries for the next year are approved. Cash bonuses for the completed fiscal year, which we refer to in this proxy statement as the "performance year," and long-term equity-based incentive compensation, are generally approved during the first quarter following completion of the performance year.

Under the Securities and Exchange Commission's rules for preparation of the following tables, discretionary cash bonuses are reported in the performance year in which they were earned, while equity-based awards are reported in the year in which they are granted by our compensation committee. We make our decisions regarding long-term equity-based incentive compensation during the first quarter following the end of the performance year. Equity-based awards for the 2009 performance year are therefore reported in the table below as 2010 compensation and awards for the 2010

performance year were made in February 2011. Similarly, awards for the 2012 performance year were made in February 2013, and are disclosed in footnote 3 to the Summary Compensation Table below.

The following table provides certain information about the vesting of restricted stock awards held by our named executive officers during the year ended December 31, 2012. No stock option held by any named executive officer vested or was exercised in 2012 or was outstanding at December 31, 2012.

Effective April 1, 2013, Stephen G. Daly stepped down as our chairman of the board, president and chief executive officer and Rick D. Hess was appointed as our new president and chief executive officer. In connection with this transition, on March 13, 2013, we entered into agreements with Messrs. Daly and Hess that provide, among other things, that:

We have one equity compensation plan under which shares are currently authorized for issuance, our 2005 Stock Incentive Plan (the "2005 Plan"). Our Amended and Restated 1996 Stock Option Plan (the "1996 Plan") expired by its terms on January 2, 2006, and no additional awards may be issued under the 1996 Plan. Each of our 1996 Plan and our 2005 Plan was approved by our stockholders prior to our initial public offering in 2005. We have no equity compensation plans that have not been approved by our stockholders. The following table provides information regarding securities authorized for issuance as of December 31, 2012 under our equity compensation plans.

The objectives of our executive compensation program are to align compensation with the interests of our stockholders, with achievement of our business goals and with the individual performance of our executives; to motivate and reward high levels of performance; and to enable our company to attract, retain and reward a senior management team that will contribute to the long-term success of our company.

Our compensation for our executive officers consists of three principal elements, each of which is determined by our compensation committee in its discretion:

Our business strategy is to introduce high performance products that are valued by customers for their ability to address technically challenging applications in attractive, growing markets. Development of such products from concept to commercial introduction can take several years, and it may take several more years for a newly introduced product to generate substantial revenue; however, the life cycle of a successful product tends to be long, often ten years or more. Because the success of our business depends on the coordinated efforts of employees in multiple disciplines over a period of years, our compensation philosophy emphasizes long-term incentives. For this reason, long-term equity-based incentive compensation has historically been the largest component of our executive officers' compensation. We believe that equity-based incentive awards motivate and reward value creation, as their benefit to the executive increases as our stock price increases. They also serve as effective retention tools due to their time-based vesting, thus increasing our ability to retain our executive officers.

At our annual meetings of stockholders in 2011 and 2012, we submitted our executive compensation program to an advisory vote of our stockholders and in each case it received the support of at least 98% of the votes cast. We consider carefully any feedback we receive from our stockholders about our executive compensation program, including the annual say on pay vote.

The compensation of our executive officers is determined by the compensation committee of our board of directors, and discussed by the committee throughout the year. Our formal annual compensation review process generally takes place in two stages. Prior to year end, salaries for the next

year are established by the committee. Cash bonuses for the completed fiscal year and long-term equity-based incentive compensation are then awarded by the committee during the first quarter on a discretionary basis, after a review of the full year's results.

The compensation committee, which is comprised entirely of non-employee directors, each of whom is independent, met nine times and acted three times by unanimous written consent during 2012. The members of the compensation committee have substantial managerial experience and wide contacts in the semiconductor industry and in the broader technology industry, upon which they rely in making their determinations. The committee also takes into account publicly available information concerning the compensation practices of other companies in the semiconductor industry, and has from time to time purchased generally available compensation reports on the semiconductor industry.

The compensation committee has also engaged Radford Surveys and Consulting, or Radford, as a consultant to the committee and has commissioned from Radford studies of specific compensation practices of selected companies. This information is used by the committee informally and primarily for purposes of comparison to ascertain whether our compensation for our executive officers is broadly competitive. Radford is an independent compensation consultant and, other than providing consulting services to the committee and the commissioned survey data described herein, has provided no other services to us or to our management. After making inquiries of Radford and after considering the factors set forth in Item 407(e)(3)(iv) of Regulation S-K, the Committee has determined that Radford's work for the committee in 2012 raised no conflicts of interest.

The committee has not historically had a formal benchmarking policy or a practice of establishing the amount of any element of our executive officers' compensation by reference to a formula or to a fixed range of percentages or percentiles of the compensation of any peer or comparison group. As a result, the determinations made by the members of our compensation committee have historically been guided to a significant degree by their collective judgment and experience.

Our chief executive officer makes recommendations with regard to the compensation of our executive officers other than himself, which are reviewed by the compensation committee. Executive officers do not participate in the process of establishing their own annual compensation.

Salaries. In setting salaries for our executive officers for 2012, we considered the salaries we paid our executive officers in prior years, information available to us regarding the compensation paid to persons having comparable responsibilities at other semiconductor companies with which we compete, as well as information concerning the responsibilities and compensation of other members of our senior management team. The committee evaluated the experience, talents and capabilities of our executive officers and recommended salaries that it believed were commensurate with these attributes and that our executive officers would find attractive. The committee also took into account its view that, in general, executives having comparable levels of responsibility in our company should receive similar levels of base compensation.

After considering these factors, for 2012 we increased the salaries of our executive officers, other than our chief executive officer, by amounts ranging from $4,000 to $10,000. These increases were generally consistent with merit raises that we awarded to our non-executive employees for 2012.

Bonuses. In general, our cash bonuses are intended to provide short-term incentives by rewarding executive officers for their contribution to our performance for the past year. The bonus determinations of our compensation committee are discretionary, and take into account the recommendations of our chief executive officer (other than with respect to himself) and judgments made by the committee

members. The compensation committee's judgments are based in part on a review, during the first quarter following the completion of the performance year, of each executive's performance in relation to objectives for that executive that are developed by the committee and reviewed by the board of directors at the beginning of the performance year. While some of the factors the committee considers are quantifiable, in our view many less quantifiable forms of contribution are equally important and are given considerable weight.

In awarding cash bonuses for 2012, the committee considered the most important factor to be our financial performance in 2012. They noted in particular that our revenue was essentially flat compared with 2011, and that our operating profit decreased year-over-year due to increased operating expenses, attributable primarily to management's decision to continue to invest in research and development in support of future growth of the business. The committee in general supported management's decision to continue to invest in research and development and also considered that, in a challenging year for the semiconductor industry generally, our financial performance in 2012 in many respects compared favorably to that of many of our competitors. However, they also believed that when operating margins decreased from 46% to 40%, a decrease in executive bonus compensation was warranted in comparison to 2011. After taking all these factors into account, our compensation committee determined in February 2013 to award to our executive officers discretionary cash bonuses in the aggregate amount of $200,000, compared to the $391,000 aggregate amount paid to our executive officers for 2011. The year-over-year decrease in the aggregate amount of the executive bonuses was commensurate with a decrease in the amount of cash incentive payments that we made to our non-executive workforce in 2012. The committee also considered the extent to which, in its judgment, each of the executive officers had attained the individual performance objectives established for him at the beginning of the year. Consistent with the recommendation of Mr. Daly, the committee decided to pay to each executive officer other than Mr. Hildreth a modest bonus in the same amount, which the committee fixed at $25,000.

New 2013 Senior Executive Cash Incentive Plan. For 2013, our compensation committee has replaced the discretionary cash bonus program employed for 2012 and described above with a new Senior Executive Cash Incentive Compensation Plan. Under this Plan, which will be used to determine our executive officers' cash bonuses for 2013, each officer is assigned a target bonus amount, ranging from 40% to 60% of his base salary. The target amount is allocated as follows: 70% will be determined based on our company financial performance in 2013 and 30% will be determined based upon the individual's performance in relation to individual performance objectives, or MBOs.

The target bonus represents the amount to be paid assuming 100% attainment of the company financial performance targets and individual MBO targets, as specified in the Plan. The actual bonus awarded will be reduced to as little as zero, or increased within stated limits, to the extent that actual performance varies from the targeted levels set forth in the Plan.

The company financial performance component of the bonus will be determined based on three equally weighted measures of our financial performance for calendar year 2013: revenue growth compared to 2012, gross margin and operating margin, compared in each case to targets set forth in the Plan. The amount of the bonus paid on account of each of these company performance measures will be equal to the portion of the target bonus that is allocated to that measure, multiplied by a pay-out factor (ranging from zero to 300%) based on the actual value of such measure for 2013, determined in accordance with a matrix set forth in the Plan.

The percentage of the MBO bonus paid to any executive will be based on the Committee's determination, in its sole discretion, as to the extent to which the executive has attained or exceeded his MBO objectives, provided that in no case will the MBO bonus be paid at more than 150% of the targeted level.

In determining the extent to which the company performance measures have been achieved, the Committee will have discretion to adjust the GAAP measure to include or exclude special or unusual items such as acquisition-related expenses. In making any such adjustments the Committee will be guided by the principle that our compensation practices should not have the effect of deterring executives from taking actions that are beneficial for our company and stockholders because they might decrease the executives' bonus payments, nor should they encourage executives to take actions that are detrimental to our company and stockholders because they might increase executives' bonus payments.

The amounts, if any, of the company performance bonus and MBO bonus for our executive officers for 2013 will be determined by the Compensation Committee following the issuance of our earnings release for the year ended December 31, 2013, and will be reported in our 2014 proxy statement.

Restricted stock awards. We believe that long-term equity-based incentives are important as a means of aligning the interests of management with stockholders' interest in the financial performance of our company and value of our stock, and also in recruiting and retaining qualified executives. Restricted stock awards under our 2005 Equity Incentive Plan are our primary form of long-term incentive compensation for our employees, including our executive officers.

In order to provide a significant incentive to executive officers to remain with our firm and create long-term value for our stockholders, our restricted stock awards to them historically vested over a five-year period, with one-third of the shares vesting on the third anniversary of the date of grant and the balance of the shares vesting on the fifth anniversary of the date of grant. Awards granted subsequent to July 2011 vest over a four-year period, in equal installments on each of the first four anniversaries of the date of grant. Restrictions on transfer of outstanding restricted stock awards lapse as the restricted stock awards vest.

Consistent with our compensation philosophy, equity-based incentive compensation was the largest component of our executive officers' total compensation for 2012, and the most significant determinant of its competitiveness. In establishing the amount of our long-term equity-based incentive awards to our executive officers made in February 2012, the compensation committee reviewed a compensation review commissioned by the committee from Radford in September 2011 (the "2011 Radford Study") that analyzed compensation data for a comparison group that combined, on an equally weighted basis, data from two groups of companies:

In selecting the 2011 Company Peer Group, the committee eliminated from the group of companies used in the previous 2010 Radford study two companies, Atheros Communications, Inc. and Verigy, Ltd., that had been acquired. They also eliminated the following nine companies whose

revenues, market capitalization or market value as a multiple of revenue the committee considered to be dissimilar to ours, such that they were less useful as indicators of competitive compensation: Advanced Analogic Technologies, Inc., Diodes, Inc., II-IV, Inc., Netlogic Microsystems, Inc., PMC-Sierra, Inc., Skyworks Solutions, Inc., STEC, Inc., STR Holdings, Inc., and Vicor Corporation. The committee added the following four companies that it considered to be more comparable to Hittite with regard to their industry focus and financial profile: Entropic Communications, Inc., Inphi Corporation, Integrated Device Technology, Inc. and Lattice Semiconductor Corporation.

To ensure that the total pay of our executive officers, other that our chief executive officer, was competitive, the committee made awards that, while smaller in magnitude that those in 2011, were still consistent in the aggregate with awards at the 50th to 75th percentile made to executives having comparable responsibilities as reflected in the 2011 Radford Study. In the case of our named executive officers, other than our chief executive officer, these awards had fair values ranging from $425,000 to $475,000. The awards to all our executive officers as a group amounted in the aggregate to approximately $3 million in 2012, a significant decrease in comparison to the awards to our executive officers in 2011, which had an aggregate value of approximately $4 million. The committee believes that the reduced magnitude of these awards is appropriate in light of our lower levels of revenue growth and profitability in 2012.

Consistent with our compensation policies for our other executive officers, our approach to the 2012 compensation of our chief executive officer, Stephen G. Daly, was to be competitive with comparable companies in the semiconductor industry. The salary for our chief executive officer is intended to provide him with a level of fixed compensation commensurate with his responsibilities and duration of employment with our company and competitive with salaries for officers holding similar positions with comparable companies in the semiconductor industry.

After considering all these factors, we increased Mr. Daly's salary from $350,000 to $364,000 for 2012, representing a 4% increase, consistent with the merit raises that we awarded to our non-executive employees for 2012. We awarded Mr. Daly in February 2012 a restricted stock award having a fair value of $500,000. The greater magnitude of Mr. Daly's restricted stock award in relation to those received by the other named executive officers was in recognition of his broader responsibility for the achievement of our strategic plan. In light of our company's financial performance, and consistent with the reduced magnitude of the other officers' awards for 2012, Mr. Daly's award was less than the $600,000 award he received in 2011. It was also substantially below the 50th percentile for value of long term equity awards made to the chief executive officers included in the 2011 Radford Study, as had also been the case in 2011. In February 2013, the committee awarded Mr. Daly a discretionary cash bonus of $25,000 for 2012, equal in amount to the modest bonus received by each of the other named executive officers.

Our executive officers receive no perquisites other than those we make available to our senior management employees generally. They are eligible to participate in standard employee benefit plans, including health, life insurance and medical reimbursement plans and a 401(k) retirement plan, on substantially the same terms as other employees who meet applicable eligibility criteria, subject to any legal limitations on the amounts that may be contributed or the benefits that may be payable under these plans. They are also entitled to the use of a company-leased automobile or to receive an allowance to reimburse them for costs related to a comparable automobile owned or leased directly by the executive, a benefit that we also make available to other management-level employees.

Section 162(m) of the Internal Revenue Code limits our tax deduction for compensation in excess of $1.0 million paid to our chief executive officer and our four other most highly compensated executive officers at the end of any fiscal year unless the compensation qualifies as "performance-based compensation." Historically, none of our executive officers has received annual compensation in an amount that would be subject us to a limitation on deductions under Section 162(m). Our compensation committee's policy with respect to Section 162(m) is to make a reasonable effort to cause compensation to be deductible by us while simultaneously providing our executive officers with appropriate rewards for their performance. However, in general our incentive compensation awards, including cash bonuses and awards under our 2005 Stock Incentive Plan, have not been structured so as to qualify as "performance-based compensation" within the meaning of Section 162(m).

Our compensation committee has submitted the following report for inclusion in this proxy statement:

Our compensation committee has reviewed and discussed with management the Compensation Discussion and Analysis contained in this proxy statement. Based on our committee's review and the discussions with management, our committee recommended to the board of directors that the Compensation Discussion and Analysis be included in this proxy statement and incorporated by reference in our Annual Report on Form 10-K for the fiscal year ended December 31, 2012.

Stock Owned by Directors, Executive Officers and Greater-Than-5% Stockholders

The following table provides information about the beneficial ownership of our common stock as of April 1, 2013, by:

In accordance with SEC rules, beneficial ownership includes any shares for which a person or entity has sole or shared voting power or investment power and any shares for which the person or entity has the right to acquire beneficial ownership within 60 days after April 1, 2013 through the exercise of any option, warrant or otherwise, and includes shares subject to all outstanding restricted stock awards whether vested or unvested. Except as noted below, we believe that the persons named in the table have sole voting and investment power with respect to the shares of common stock set forth opposite their names. Percentage of beneficial ownership is based on 31,574,455 shares of common stock outstanding as of April 1, 2013. Shares included in the "Right to Acquire" column represent shares that are subject to options exercisable within 60 days of April 1, 2013. The address of our

executive officers and directors is in care of Hittite Microwave Corporation, 2 Elizabeth Drive, Chelmsford, Massachusetts 01824.

We have adopted a stock ownership policy for our officers and members of our board of directors. Under our stock ownership policy for officers, our chief executive officer is expected to acquire and hold at least that number of vested shares of our common stock as has an aggregate market value of no less than three times his current annual rate of salary and each other officer is expected to acquire and hold that number of shares as has an aggregate market value of not less than one times his current annual rate of salary. Under our stock ownership policy for directors, each director is expected to acquire and hold that number of vested shares as has an aggregate market value of not less than $200,000.

We expect our officers to attain their stock ownership targets within five years of their first appointment as officers or, if later, by December 31, 2014. We expect our directors to attain their stock ownership targets within five years of the date of their first election to the board.

Until his or her stock ownership target is met, each executive officer and director is expected to retain at least two-thirds of the net shares that vest under any restricted stock award or that are acquired upon exercise of any option, after deducting shares withheld, sold or otherwise necessary to offset the payment of any exercise price or tax obligations. This retention requirement is limited, in the case of executive officers, to awards made in 2010 and thereafter. If the value of vested shares held by an officer or director who has met the applicable stock ownership target drops below the target due to a subsequent decline in our stock price, the retention requirement is reinstated until the applicable target is again met.

We have also adopted a policy that prohibits our officers, directors or employees from entering into any short sale of our securities, buying or selling publicly traded options on our common stock or hedging their positions in our securities, including through the use of instruments such as prepaid variable forwards, equity swaps, collars or exchange funds.

Section 16(a) of the Securities Exchange Act of 1934 requires our directors and executive officers, and persons who beneficially own more than ten percent of a registered class of our equity securities, to file reports of ownership of, and transactions in, our securities with the Securities and Exchange Commission. These directors, executive officers and ten-percent stockholders are also required to furnish us with copies of all Section 16(a) forms they file.

Based solely on a review of the copies of such forms received by us, and on written representations from certain reporting persons, we believe that during 2012 our directors, officers and ten-percent stockholders complied with all applicable Section 16(a) filing requirements, with the exceptions noted below.

The primary role of our audit committee is to assist our board of directors in fulfilling its oversight responsibilities by reviewing the financial information proposed to be provided to stockholders and others, the adequacy of the system of internal control over financial reporting and disclosure controls and procedures established by management and the board, and the audit process and the independent auditors' qualifications, independence and performance.

Management is responsible for establishing and maintaining the company's system of internal controls and for preparation of the company's financial statements. Our independent registered public accounting firm, PricewaterhouseCoopers LLP, is responsible for performing an audit of our consolidated financial statements in accordance with generally accepted auditing standards and issuing an opinion on the financial statements. The audit committee has met and held discussions with management and our independent auditors, and has also met separately with our independent auditors, without management present, to review the adequacy of our internal controls, financial reporting practices and audit process.

The audit committee has reviewed and discussed our audited consolidated financial statements for the year ended December 31, 2012 with management and the independent auditors. As part of this review, the audit committee discussed with PricewaterhouseCoopers the communications required by generally accepted auditing standards, including those described in Statement on Auditing Standards No. 61, "Communication with Audit Committees."

The audit committee has received from PricewaterhouseCoopers a written statement describing all relationships between that firm and Hittite that might bear on the auditors' independence, consistent with Public Company Accounting Oversight Board Ethics and Independence Rule 3526, Communication with Audit Committees Concerning Independence. The audit committee has discussed the written statement with the independent auditors, and has considered whether the independent auditors' provision of any consultation and other non-audit services to Hittite is compatible with maintaining the auditors' independence.

Based on the above-mentioned reviews and discussions with management and the independent auditors, the audit committee recommended to the board of directors that Hittite's audited consolidated financial statements be included in its Annual Report on Form 10-K for the year ended December 31, 2012 as filed with the Securities and Exchange Commission.

PricewaterhouseCoopers LLP have been selected by the audit committee of the board of directors as the independent registered public accounting firm to audit our financial statements for the year ending December 31, 2013. PricewaterhouseCoopers also served as our auditors in 2012. We expect that representatives of PricewaterhouseCoopers will attend the meeting, will have an opportunity to make a statement if they desire to do so, and will be available to respond to appropriate questions.

The following is a summary of the fees for professional services rendered by PricewaterhouseCoopers LLP for 2012 and 2011:

Audit fees. Audit fees represent fees for professional services performed by PricewaterhouseCoopers LLP for the audit of our annual financial statements and the review of our quarterly financial statements, as well as services that are normally provided in connection with statutory and regulatory filings or engagements and related expenses.

Audit-related fees. Audit-related fees represent fees for assurance and related services performed by PricewaterhouseCoopers LLP that are reasonably related to the performance of the audit or review of our financial statements, including consultation on accounting standards or accounting for specific transactions.

Tax fees. Tax fees represent fees for professional services performed by PricewaterhouseCoopers LLP with respect to tax compliance, tax advice and tax planning and related expenses. These services include assistance with the preparation of federal, state, and foreign income tax returns.

All other fees. All other fees represent fees for products and services provided by PricewaterhouseCoopers LLP, other than those disclosed above.

Our audit committee approves each engagement for audit or non-audit services before we engage PricewaterhouseCoopers LLP to provide those services. All audit and non-audit services require pre-approval by the audit committee.

Our audit committee's pre-approval policies or procedures do not allow our management to engage PricewaterhouseCoopers LLP to provide any specified services without specific audit committee preapproval of the engagement for those services. All of the services provided by PricewaterhouseCoopers LLP during 2012 were pre-approved.

Our audit committee has adopted procedures for the treatment of complaints regarding accounting, internal accounting controls or auditing matters, including procedures for the confidential and anonymous submission by our directors, officers and employees of concerns regarding questionable accounting, internal accounting controls or auditing matters. These procedures are set forth in our code of ethics. See "Information About Our Board of Directors and Management—Code of Ethics."

Neither we nor our board of directors intends to propose any matters of business at the meeting other than the proposals described in this proxy statement. Neither we nor our board know of any matters to be proposed by others at the meeting.

Under applicable rules of the Securities and Exchange Commission, a stockholder who intends to request that a proposal to be made at the 2014 annual meeting of stockholders be included in our 2014 proxy statement must submit the proposal to us by January 15, 2014. In order for the proposal to be included in the proxy statement, the stockholder submitting the proposal must meet certain eligibility standards and must comply with procedures established by the Securities and Exchange Commission, and the proposal must comply with the requirements as to form and substance established by applicable laws and regulations. The proposal must be mailed to our Secretary at our address set forth on the notice of meeting appearing on the cover of this proxy statement.

In addition, under our by-laws as amended in January 2013, for a stockholder's proposal to be brought before the 2014 annual meeting of our stockholders, the stockholder must give written notice to our Secretary at the address specified no later than sixty (60) days and not more than ninety (90) days prior to the first anniversary of the preceding year's annual meeting, which will be May 15, 2014, and if the annual meeting is advanced more than thirty (30) days prior to or delayed by more than sixty (60) days after that date, then notice must be given to our Secretary by the later of sixty (60) days prior to the date of the annual meeting or ten (10) days following the public disclosure of the date of the annual meeting is given.
