EX-99.(a)(1)(A)

THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 11:59 P.M.,

NEW YORK CITY TIME, ON MARCH 1, 2016, UNLESS THE OFFER IS EXTENDED.

The Offer (as defined herein) is being made pursuant to the Agreement and Plan of Merger, dated as of January 15, 2016 and amended on February 1, 2016 (as it may be further amended, modified or supplemented from time to time in accordance with its terms, the “Merger Agreement”), by and among II-VI Incorporated, a Pennsylvania corporation (“Parent”), Regulus Acquisition Sub, Inc., a Delaware corporation (“Purchaser”) and a wholly-owned subsidiary of II-VI, and ANADIGICS, Inc., a Delaware corporation (“Anadigics”). Purchaser is offering to purchase all of the outstanding shares of common stock, par value $0.01 per share, of Anadigics (the “Shares”), at a price of $0.66 per Share (the “Offer Price”), net to the seller in cash, without interest, less any applicable withholding taxes, upon the terms and subject to the conditions set forth in this offer to purchase (this “Offer to Purchase”) and the related letter of transmittal (the “Letter of Transmittal”), which, together with any amendments or supplements hereto and thereto, collectively constitute the “Offer.”

Pursuant to the Merger Agreement, as soon as practicable following the consummation of the Offer and subject to the satisfaction or waiver of the remaining conditions set forth in the Merger Agreement, Purchaser will merge with and into Anadigics (the “Merger”), with Anadigics continuing as the surviving corporation in the Merger and as a wholly-owned subsidiary of II-VI. At the effective time of the Merger (the “Effective Time”), each Share then outstanding (other than (i) Shares then held by II-VI, Purchaser, Anadigics or their respective subsidiaries and (ii) Shares that are held by any stockholders of Anadigics who properly demand appraisal in connection with the Merger as described in Section 16 — “Certain Legal Matters; Regulatory Approvals — Appraisal Rights”) will be converted into the right to receive the Offer Price, without interest, less any applicable withholding taxes. Under no circumstances will interest be paid with respect to the purchase of Shares pursuant to the Offer, regardless of any extension of the Offer or any delay in making payment for Shares.

On January 15, 2016, in connection with entering into the Merger Agreement, Anadigics terminated the existing Agreement and Plan of Merger, dated as of November 11, 2015 (the “Aloha Merger Agreement”) by and among Anadigics, Aloha Holding Company, Inc., a Delaware corporation (“Aloha”), and Aloha Acquisition Sub, Inc., a Delaware corporation (“Aloha Sub”) and wholly owned subsidiary of Aloha. Pursuant to the Aloha Merger Agreement, Aloha Sub had commenced on November 24, 2015 a tender offer for all of the Shares at a price per share of $0.35, without interest (the “Aloha Offer”). In connection with the termination of the Aloha Merger Agreement, Aloha Sub terminated the Aloha Offer on January 19, 2016.

THE BOARD OF DIRECTORS OF ANADIGICS UNANIMOUSLY RECOMMENDS THAT YOU TENDER ALL OF YOUR SHARES IN THE OFFER.

After careful consideration, the Board of Directors of Anadigics (the “Anadigics Board”) unanimously (1) determined that the Merger Agreement and the transactions contemplated thereby, including the Offer and the Merger, are advisable, fair to and in the best interests of Anadigics and its stockholders, (2) approved, and declared advisable, the Merger Agreement, the Offer, the Merger and the transactions contemplated by the Merger Agreement in accordance with the requirements of Delaware law, (3) resolved to recommend that Anadigics’s stockholders accept the Offer and tender their Shares to Purchaser pursuant to the Offer, and (4) approved the termination of the Aloha Merger Agreement.

The Offer is not subject to any financing condition. The Offer is conditioned upon: (a) there being validly tendered and not properly withdrawn prior to 11:59 P.M., New York City time, on March 1, 2016 (the “Expiration Date,” unless Purchaser extends the Offer pursuant to and in accordance with the terms of the Merger Agreement, in which event “Expiration Date” will mean the latest time and date at which the Offer, as so extended by us, will expire) (not including Shares tendered pursuant to guaranteed delivery procedures and not actually delivered prior to the Expiration Date) the number of Shares which, when added to any Shares owned by II-VI or any of its subsidiaries, would represent at least a majority of the outstanding Shares of Anadigics, and (b) other customary conditions as set forth in Annex I to the Merger Agreement have been satisfied or waived. See Section 15 — “Conditions to the Offer.” After the consummation of the Offer and subject to the satisfaction or waiver of the remaining conditions set forth in the Merger Agreement, II-VI, Purchaser and Anadigics will cause the Merger to become effective as soon as practicable without a meeting of stockholders of Anadigics in accordance with Section 251(h) of the General Corporation Law of the State of Delaware (the “DGCL”).

A summary of the principal terms of the Offer appears on pages i through viii below. You should read this entire Offer to Purchase and the Letter of Transmittal carefully before deciding whether to tender your Shares into the Offer.

Any stockholder of Anadigics wishing to tender all or any portion of its Shares to Purchaser pursuant to the Offer should, prior to the Expiration Date, (i) complete and execute the Letter of Transmittal that is enclosed with this Offer to Purchase in accordance with the instructions contained therein, and mail or deliver the Letter of Transmittal together with the certificates representing your Shares and any other required documents, to Computershare Trust Company, N.A., in its capacity as depositary for the Offer (the “Depositary”), (ii) if applicable, tender your Shares by book-entry transfer by following the procedures described in Section 3 — “Procedures for Accepting the Offer and Tendering Shares — Book-Entry Transfer” or (iii) if applicable, request that your broker, dealer, commercial bank, trust company or other nominee effect the transaction for the stockholder. A stockholder who holds Shares registered in the name of a broker, dealer, commercial bank, trust company or other nominee must contact such nominee in order to tender such Shares to Purchaser pursuant to the Offer.

Any stockholder of Anadigics who wishes to tender Shares pursuant to the Offer and the certificates representing such Shares are not immediately available, or such stockholder cannot comply in a timely manner with the procedures for tendering Shares by book-entry transfer or such stockholder cannot deliver all required documents to the Depositary prior to the Expiration Date, may tender such Shares to Purchaser pursuant to the Offer by following the procedures for guaranteed delivery described in Section 3 — “Procedures for Accepting the Offer and Tendering Shares — Guaranteed Delivery.”

Georgeson Inc., the information agent for the Offer (the “Information Agent”), may be contacted at the address and telephone numbers set forth above and on the back cover of this Offer to Purchase for questions and/or requests for additional copies of this Offer to Purchase, the Letter of Transmittal, the notice of guaranteed delivery and other tender offer materials free of charge. Stockholders may also contact their broker, dealer, commercial bank, trust company or other nominee for assistance.

This Offer to Purchase and the Letter of Transmittal contain important information, and you should read both carefully and in their entirety before making a decision with respect to the Offer.

The Offer has not been approved or disapproved by the U.S. Securities and Exchange Commission (“SEC”) or any state securities commission, nor has the SEC or any state securities commission passed upon the fairness or merits of or upon the accuracy or adequacy of the information contained in this Offer to Purchase. Any representation to the contrary is unlawful.

The following are answers to some questions that you, as a stockholder of Anadigics, may have about the Offer. This summary term sheet highlights selected information from this offer to purchase (this “Offer to Purchase”) and may not contain all of the information that is important to you and is qualified in its entirety by the more detailed descriptions and explanations contained in this Offer to Purchase and the related letter of transmittal (the “Letter of Transmittal”), which, together with any amendments or supplements hereto and thereto, collectively constitute the “Offer.” To better understand the Offer and for a complete description of the terms of the Offer, you should read this Offer to Purchase, the Letter of Transmittal and the other documents to which we refer you carefully and in their entirety. Questions or requests for assistance may be directed to Georgeson Inc., our information agent (the “Information Agent”), at the address and telephone numbers set forth for the Information Agent on the back cover of this Offer to Purchase. Unless otherwise indicated in this Offer to Purchase or the context otherwise requires, all references in this Offer to Purchase to “we,” “our” or “us” refer to Purchaser.

Our name is Regulus Acquisition Sub, Inc. and we are a wholly-owned subsidiary of II-VI. We were formed for the purpose of making the Offer and thereafter consummating the merger (the “Merger”) with and into Anadigics, with Anadigics continuing as the surviving corporation in the Merger and as a wholly-owned subsidiary of II-VI. To date, we have not carried on any activities other than those related to our formation, the Merger Agreement, the Offer and the Merger.

II-VI is a corporation incorporated under the laws of the State of Pennsylvania. II-VI is a publicly held company focused on development and manufacturing of engineered materials and opto-electronic components for diversified applications in the industrial, optical communications, military, life sciences, semiconductor equipment and consumer markets. See the “Introduction” and Section 8 — “Certain Information Concerning Purchaser and II-VI.”

We are making the Offer to purchase all of the outstanding Shares of Anadigics on the terms and subject to the conditions set forth in this Offer to Purchase and the Letter of Transmittal. See the “Introduction” and Section 1 — “Terms of the Offer.”

We are making the Offer pursuant to the Agreement and Plan of Merger, dated as of January 15, 2016 and amended on February 1, 2016, by and among II-VI, Anadigics and us (as it may be further amended, modified or supplemented from time to time in accordance with its terms, the “Merger Agreement”), in order to acquire control of, and ultimately following the Merger, the entire equity interest in, Anadigics, while allowing Anadigics’s stockholders an opportunity to receive the Offer Price by tendering their Shares in the Offer. If the Offer is consummated, subject to the satisfaction or waiver of the remaining conditions set forth in the Merger Agreement, we, II-VI and Anadigics will consummate the Merger as soon as practicable thereafter in accordance with the General Corporation Law of the State of Delaware (the “DGCL”). At the effective time of the Merger (the “Effective Time”), Anadigics will become a wholly-owned subsidiary of II-VI. See Section 12 — “Purpose of the Offer; Plans for Anadigics.”

How much are you offering to pay and what is the form of payment? Will I have to pay any fees or commissions?

We are offering to pay $0.66 per Share, net to the seller in cash, without interest, less any applicable withholding taxes.

If you are the record owner of your Shares and you directly tender your Shares to us in the Offer, you will not have to pay brokerage fees, commissions or similar expenses. If you own your Shares through a broker, dealer, commercial bank, trust company or other nominee and such nominee tenders your Shares on your behalf, such nominee may charge you a fee for doing so. You should consult with your broker, dealer, commercial bank, trust company or other nominee to determine whether any charges will apply. See the “Introduction,” Section 1 — “Terms of the Offer” and Section 2 — “Acceptance for Payment and Payment for Shares.”

After careful consideration, the Anadigics Board unanimously (1) determined that the Merger Agreement and the transactions contemplated thereby, including the Offer and the Merger, are advisable, fair to and in the best interests of Anadigics and its stockholders, (2) approved, and declared advisable, the Merger Agreement, the Offer, the Merger and the transactions contemplated by the Merger Agreement in accordance with the requirements of Delaware law and (3) resolved to recommend that Anadigics’s stockholders accept the Offer and tender their Shares to Purchaser pursuant to the Offer.

A description of the reasons for the Anadigics Board’s adoption of the Offer and the Merger is set forth in Anadigics’s Solicitation/Recommendation Statement on Schedule 14D-9 (the “Schedule 14D-9”) that is being filed with the Securities and Exchange Commission (the “SEC”) and, together with this Offer to Purchase, the Letter of Transmittal and other related materials, mailed to Anadigics’s stockholders in connection with the Offer. See the “Introduction” to this Offer to Purchase.

The Offer is subject to several customary conditions including, among others, satisfaction of the Minimum Condition.

The term “Minimum Condition” is defined in Section 15 — “Conditions to the Offer”, and generally requires that there is validly tendered and not withdrawn immediately prior to the Expiration Date (as defined below) of the Offer that number of Shares which, when added to the Shares owned by II-VI or any of its subsidiaries (if any), would represent at least a majority of the Shares outstanding of Anadigics (assuming conversion or exercise of all derivative securities convertible or exercisable immediately prior to the Expiration Date, regardless of the conversion or exercise price), excluding for the purposes of this condition any Shares tendered pursuant to guaranteed delivery procedures and not actually delivered prior to the Expiration Date. Assuming there continue to be 89,735,630 Shares outstanding and 912,058 Shares continue to be subject to exercisable options to purchase, the Minimum Condition would be satisfied if at least 45,323,845 Shares are validly tendered and not properly withdrawn prior to the Expiration Date.

The Offer is also subject to a number of other important conditions. A more detailed discussion of the conditions to consummate the Offer is contained in Section 15 — “Conditions to the Offer.”

Yes. II-VI will provide us with sufficient funds to purchase all Shares validly tendered in the Offer and will provide funding to consummate the Merger (which includes, among other things, payment to acquire the remaining Shares in the Merger and payment in respect of outstanding in-the-money options and certain restricted stock unit awards of Anadigics), and to pay related transaction fees and expenses. II-VI expects to fund such cash requirements from its cash on hand and available borrowings under its credit facility.

The Offer is not subject to any financing condition. We estimate that we will need approximately $61 million to purchase all Shares pursuant to the Offer, to fund any payments to consummate the Merger and to pay related transaction fees and expenses. See Section 9 — “Source and Amount of Funds.”

Is your financial condition relevant to my decision to tender my Shares in the Offer?

No. We do not think that our financial condition is relevant to your decision whether to tender Shares and accept the Offer because:

See Section 9 — “Source and Amount of Funds” and Section 11 — “The Merger Agreement; Other Agreements.”

Unless we extend the Offer, you will have until 11:59 P.M., New York City time, on March 1, 2016 (the “Expiration Date,” unless we extend the Offer pursuant to and in accordance with the terms of the Merger Agreement, in which event “Expiration Date” will mean the latest time and date at which the Offer, as so extended by us, will expire) to tender your Shares in the Offer. Further, if you cannot deliver everything that is required in order to make a valid tender by that time, you may still participate in the Offer by using the guaranteed delivery procedure that is described later in this Offer to Purchase by the Expiration Date. See Section 1 — “Terms of the Offer” and Section 3 — “Procedures for Accepting the Offer and Tendering Shares.”

Yes, the Offer can be extended. In some cases, we are required to extend the Offer beyond the initial Expiration Date, but in no event will we be required to extend the Offer beyond the End Date (as defined below).

If we extend the Offer, such extension will extend the time that you will have to tender your Shares. See Section 1 — “Terms of the Offer.”

If we extend the Offer, we will inform the Depositary of that fact and will make a public announcement of the extension no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled Expiration Date.

If we elect to provide a subsequent offering period as described below, a public announcement of such election will be made no later than 9:00 a.m., New York City time, on the next business day following the Expiration Date. See Section 1 — “Terms of the Offer.”

To tender your Shares, you must deliver the certificates representing your Shares, together with a properly completed and duly completed Letter of Transmittal (or, in the case of book-entry transfer of Shares, either such Letter of Transmittal or an Agent’s Message (as defined in Section 3 — “Procedures for Accepting the Offer and Tendering Shares — Valid Tender of Shares”) in lieu of such Letter of Transmittal), and any other documents required by the Letter of Transmittal, to the Depositary prior to the Expiration Date. If your Shares are held in street name (i.e., through a broker, dealer, commercial bank, trust company or other nominee), your Shares can be tendered by such nominee through the Depositary. If you are unable to deliver any required document or instrument to the Depositary prior to the Expiration Date, you may still participate in the Offer by having a broker, a bank or any other fiduciary that is an eligible guarantor institution guarantee that the missing items will be received by the Depositary by using the enclosed notice of guaranteed delivery (the “Notice of Guaranteed

Delivery”). For the tender to be valid, however, the Depositary must receive the Notice of Guaranteed Delivery prior to the Expiration Date and must then receive the missing items within three NASDAQ trading days after the date of execution of such Notice of Guaranteed Delivery. See Section 3 — “Procedures for Accepting the Offer and Tendering Shares.”

Shares tendered into the Offer may be withdrawn at any time prior to the Expiration Date. Thereafter, tenders of Shares are irrevocable, except that they may also be withdrawn after April 2, 2016, which is the 60th day from the commencement of the Offer, unless such Shares have already been accepted for payment by us pursuant to the Offer. If you tendered your Shares by giving instructions to a broker, dealer, commercial bank, trust company or other nominee, you must instruct such nominee to arrange for the withdrawal of your Shares. See Section 4 — “Withdrawal Rights.” You may not withdraw Shares tendered during any subsequent offering period that we may elect to provide. See Section 4 — “Withdrawal Rights.”

To properly withdraw any of your previously tendered Shares, you must deliver a written notice of withdrawal with the required information (as specified in this Offer to Purchase and in the Letter of Transmittal) to the Depositary while you still have the right to withdraw Shares. If you tendered your Shares by giving instructions to a broker, dealer, commercial bank, trust company or other nominee, you must instruct such nominee to arrange for the proper withdrawal of your Shares. You may not withdraw Shares tendered during any subsequent offering period that we may elect to provide. See Section 4 — “Withdrawal Rights.”

No. We have not entered into any agreements with any stockholders of Anadigics under which those stockholders have agreed to tender Shares in the Offer.

Prior to the consummation of the Offer, will the Shares continue to be listed on NASDAQ?

In June 2015 Anadigics received a notice from NASDAQ indicating that the Shares may be delisted as early as December 2015 due to non-compliance with certain minimum bid requirements. Anadigics applied to transfer the Shares from the NASDAQ Global Select Market to the NASDAQ Capital Market and in December 2015, Anadigics was notified by NASDAQ that the application was approved. As of December 17, 2015, the Shares were transferred to the NASDAQ Capital Market. The Shares will continue to trade on the NASDAQ Capital Market until June 13, 2016 pending the listing for the Shares regaining compliance with applicable NASDAQ listing rules. See Section 13 — “Certain Effects of the Offer —Stock Listing.”

Upon the successful consummation of the Offer, will Shares continue to be publicly traded?

If the Shares are not delisted from NASDAQ prior to the consummation of the Offer as described above, and if all of the conditions to the Offer are satisfied or waived (see Section 15 — “Conditions to the Offer”) and we purchase all tendered Shares, prior to the Merger becoming effective, there may then be so few remaining stockholders and publicly-held Shares that such Shares will no longer be eligible to be traded on the NASDAQ or any other securities exchange and there may not be a public trading market for such Shares. Following the consummation of the Offer and subject to the satisfaction of the remaining conditions set forth in the Merger Agreement, we, II-VI and Anadigics will consummate the Merger as soon as practicable in accordance with Section 251(h) of the DGCL. Following consummation of the Merger, no Shares will be publicly owned, and Anadigics will deregister with the SEC and will no longer be a public company. See Section 13 — “Certain Effects of the Offer.” Because the Merger will be governed by Section 251(h) of the DGCL, no stockholder vote will be required to consummate the Merger. We do not expect there to be a significant period of time between the consummation of the Offer and the consummation of the Merger.

If you do not consummate the Offer, will you nevertheless consummate the Merger?

No. None of us, II-VI or Anadigics are under any obligation to pursue or consummate the Merger if the Offer has not been earlier consummated.

Subject to the provisions of Section 251(h) of the DGCL and our obligation to consummate the Merger as soon as practicable following the consummation of the Offer and satisfaction of the remaining conditions set forth in the Merger Agreement, we may elect to provide a subsequent offering period (and one or more extensions thereof) of not less than three business days nor more than twenty business days, during which time Anadigics’s stockholders whose Shares have not been tendered prior to the Expiration Date (or whose Shares were tendered and later withdrawn prior to the Expiration Date) may tender, but not withdraw, their Shares and receive the Offer Price. See Section 1 — “Terms of the Offer” and Section 4 — “Withdrawal Rights.”

What is the difference between an extension of the Offer and a subsequent offering period?

If the Offer is extended, no Shares will be accepted or paid for until following the Expiration Date (as so extended), and you will be able to withdraw your Shares until the Expiration Date.

A subsequent offering period, if one is provided, would occur after the time we accept for payment Shares tendered in the Offer (the “Acceptance Time”) and after we have become obligated to pay for all Shares that were validly tendered and not properly withdrawn prior to the Expiration Date. Shares that are validly tendered during a subsequent offering period will be accepted and paid for promptly after they are received and cannot be withdrawn. See Section 1 — “Terms of the Offer” and Section 4 —“Withdrawal Rights.”

Appraisal rights are not available to the holders of Shares in connection with the Offer. However, if the Merger is consummated, the holders of Shares immediately prior to the Effective Time who (i) did not tender their Shares in the Offer, (ii) follow the procedures set forth in Section 262 of the DGCL and (iii) do not thereafter withdraw their demand for appraisal of such Shares or otherwise lose their appraisal rights, in each case in accordance with the DGCL, will be entitled to have their Shares appraised by the Delaware Court of Chancery and receive payment of the “fair value” of such Shares, exclusive of any element of value arising from the accomplishment or expectation of the Merger, together with a fair rate of interest, as determined by such court. The “fair value” could be more or less than, or the same as, the Offer Price or the consideration payable in the Merger (which is equivalent in amount to the Offer Price). See Section 16 — “Certain Legal Matters — Appraisal Rights.” Concurrently with the commencement of the Offer, Anadigics is distributing the Schedule 14D-9, which contains important information regarding how a holder of Shares may exercise its appraisal rights.

Following the consummation of the Offer and subject to the satisfaction or waiver of the remaining conditions set forth in the Merger Agreement, we, II-VI and Anadigics will consummate the Merger as soon as practicable. If the Merger is consummated, then stockholders who did not tender their Shares into the Offer will receive the same amount of cash per Share that they would have received had they tendered their Shares into the Offer (i.e., the Offer Price), subject to any appraisal rights properly exercised by such stockholders in accordance with Delaware law. Therefore, if the Merger takes place, the only difference to you between tendering your Shares into the Offer and not tendering your Shares into the Offer would be that, if you tender your Shares, you may be paid earlier and no appraisal rights will be available. No interest will be paid for Shares acquired in the Merger.

Furthermore, following the consummation of the Offer until the Effective Time, there may then be so few remaining stockholders and publicly held Shares that such Shares will no longer be eligible to be traded on the NASDAQ or any other securities exchange and there may not be a public trading market for such Shares. See the “Introduction” and Section 13 — “Certain Effects of the Offer.”

Because the Merger will be governed by Section 251(h) of the DGCL, no stockholder vote will be required to consummate the Merger. We do not expect there to be a significant period of time between the consummation of the Offer and the consummation of the Merger. See Section 11 — “The Merger Agreement; Other Agreements” and Section 12 — “Purpose of the Offer; Plans for Anadigics — Purpose of the Offer.”

On November 11, 2015, the last full trading day before the execution of the Aloha Merger Agreement and the Aloha Offer was announced, the closing price of the Shares on NASDAQ was $0.24 per Share. On November 23, 2015, the last full day of trading before the commencement of the Aloha Offer, the closing price of the Shares on NASDAQ was $0.34 per Share. On January 15, 2016, the last full trading day before the execution of the II-VI Merger Agreement and the Offer was announced, the closing price of the Shares on NASDAQ was $0.68 per Share. On February 1, 2016, the last full day of trading before the commencement of the Offer, the closing price of the Shares on NASDAQ was $0.69 per Share. We encourage you to obtain a recent quotation for Shares in deciding whether to tender your Shares. See Section 6 — “Price Range of Shares; Dividends.”

If the conditions to the Offer as set forth in Section 15 —“Conditions to the Offer” are satisfied or waived and we consummate the Offer and accept your Shares for payment, you will be entitled to promptly receive an amount equal to the number of Shares you tendered into the Offer multiplied by the Offer Price, net to you in cash, without interest, less any applicable withholding taxes. We will pay for your validly tendered and not properly withdrawn Shares by depositing the aggregate Offer Price therefor with the Depositary, which will act as your agent for the purpose of receiving payments from us and transmitting such payments to you. In all cases, payment for tendered Shares will be made only after timely receipt by the Depositary of (i) certificates representing such Shares or a confirmation of a book-entry transfer of such Shares as described in Section 3 — “Procedures for Accepting the Offer and Tendering Shares — Book-Entry Transfer,” (ii) a properly completed and duly executed Letter of Transmittal, together with any required signature guarantees or, in the case of book-entry transfer of Shares, either such Letter of Transmittal or an Agent’s Message in lieu of such Letter of Transmittal and (iii) any other required documents for such Shares. See Section 1 — “Terms of the Offer” and Section 2 — “Acceptance for Payment and Payment for Shares.”

The Offer is being made for all outstanding Shares, and not for options to purchase Shares, restricted stock unit awards or other equity awards (collectively, “Equity Awards”). Equity Awards may not be tendered into the Offer. If you wish to tender Shares underlying Equity Awards, you must first exercise such awards (to the extent exercisable) in accordance with their terms in sufficient time to tender the Shares received into the Offer.

Pursuant to the Merger Agreement, each option to purchase Shares granted under any equity plan of Anadigics (each, a “Anadigics Option”) that is outstanding immediately prior to the Effective Time, whether vested or unvested, will be cancelled and, in consideration for such cancellation, the holder of such Anadigics Option will automatically receive (as soon as practicable but in no event more than 30 days following the Effective Time) an amount in cash equal to (i) the total number of Shares subject to such Anadigics Option, multiplied by (ii) the excess, if any, of (A) the Offer Price over (B) the per share exercise price for such Anadigics Option (less all applicable tax deductions and withholdings required by law to be withheld in respect of such payment and without interest).

Pursuant to the Merger Agreement, each time-based restricted stock unit award, whether vested or unvested, and each performance-based restricted stock unit award earned for 2013 performance and for the first tranche of 2015 performance, in each case granted under any equity plan of Anadigics (each, a “Anadigics Restricted Stock Unit Award”), that is outstanding immediately prior to the Effective Time will be cancelled and, in consideration for such cancellation, the holder of such Anadigics Restricted Stock Unit will automatically receive (as soon as practicable but in no event more than 30 days following the Effective Time) an amount in cash equal to (i) the total number of Shares subject to such Anadigics Restricted Stock Unit, multiplied by (ii) the Offer Price (less all applicable tax deductions and withholdings required by law to be withheld in respect of such payment and without interest). All other unvested performance-based restricted stock unit awards will be cancelled without payment of any consideration.

See Section 11 — “The Merger Agreement; Other Agreements — The Merger Agreement — Treatment of Anadigics Options and Anadigics Restricted Stock Unit Awards.”

What are the U.S. federal income tax consequences of the Offer and the Merger?

The receipt of cash by you in exchange for your Shares pursuant to the Offer or the Merger (or pursuant to the exercise of appraisal rights in accordance with Delaware law) will be a taxable transaction for U.S. federal income tax purposes if you are a United States Holder (as defined in Section 5 — “Certain Material U.S. Federal Income Tax Consequences of the Offer and the Merger — United States Holders”). In general, you will recognize gain or loss equal to the difference between your adjusted tax basis in Shares that you tender into the Offer or exchange in the Merger (or retain for exercise of appraisal rights) and the amount of cash you receive for such Shares. If you are a United States Holder and you hold your Shares as a capital asset, the gain or loss that you recognize will be a capital gain or loss and will be treated as a long-term capital gain or loss if you have held such Shares for more than one year. If you are a Non-United States Holder (as defined in Section 5 — “Certain Material U.S. Federal Income Tax Consequences of the Offer and the Merger — Non-United States Holders”), you will generally not be subject to U.S. federal income tax on gain recognized on Shares you tender into the Offer or exchange in the Merger (or retain for exercise of appraisal rights). You should consult your tax advisor about the particular tax consequences to you of tendering your Shares into the Offer, exchanging your Shares in the Merger or exercising appraisal rights. See Section 5 — “Certain Material U.S. Federal Income Tax Consequences of the Offer and the Merger” for a discussion of certain material U.S. federal income tax consequences of tendering Shares in the Offer or exchanging Shares in the Merger or exercising appraisal rights.

You may contact Georgeson, Inc., the Information Agent for the Offer, at the address and telephone numbers listed below if you have any questions about the Offer.

Regulus Acquisition Sub, Inc., a Delaware corporation (“Purchaser,” “we,” “us,” or “our”) and a wholly-owned subsidiary of II-VI Incorporated, a Pennsylvania corporation (“II-VI”), hereby offers to purchase (the “Offer”) all of the outstanding shares of common stock, par value $0.01 per share (the “Shares”), of ANADIGICS, Inc., a Delaware corporation (“Anadigics”), at a price of $0.66 per Share (the “Offer Price”), net to the seller in cash, without interest, less any applicable withholding taxes, upon the terms and conditions set forth in this Offer to Purchase (as it may be amended and supplemented from time to time, the “Offer to Purchase”) and in the related Letter of Transmittal (as it may be amended or supplemented from time to time, the “Letter of Transmittal”).

The Offer is being made pursuant to the Agreement and Plan of Merger, dated January 15, 2016 and amended on February 1, 2016 (as it may be further amended and supplemented from time to time, the “Merger Agreement”), by and among II-VI, Purchaser and Anadigics. Under the Merger Agreement, after the completion of the Offer and subject to specified conditions, Purchaser will merge with and into Anadigics (the “Merger”), with Anadigics continuing as the surviving corporation and a wholly-owned subsidiary of II-VI (the “Surviving Corporation”). At the effective time of the Merger (the “Effective Time”), each Share then outstanding (other than (i) Shares then held by II-VI, Purchaser, Anadigics or their respective subsidiaries, and (ii) Shares that are held by any stockholders of Anadigics who properly demand appraisal in connection with the Merger as described in Section 16 — “Certain Legal Matters — Appraisal Rights”) will be converted into the right to receive the Offer Price, without interest, less any applicable withholding taxes. The Merger Agreement is described in detail in Section 11 — “The Merger Agreement; Other Agreements” of this Offer to Purchase.

The Offer is conditioned upon, among other things, satisfaction of the Minimum Condition (as defined below), and other customary conditions. The term “Minimum Condition” is defined in Section 15 — “Conditions to the Offer”, and generally requires that there is validly tendered and not withdrawn immediately prior to the Expiration Date (as defined below) of the Offer that number of Shares which, when added to the Shares owned by II-VI or any of its subsidiaries (if any), would represent at least a majority of the Shares outstanding of Anadigics (assuming conversion or exercise of all derivative securities convertible or exercisable immediately prior to the Expiration Date, regardless of the conversion or exercise price), excluding for the purposes of this condition Shares tendered pursuant to guaranteed delivery procedures and not actually delivered prior to the Expiration Date. See Section 15 — “Conditions to the Offer.” The Minimum Condition may not be waived without the prior written consent of Anadigics.

According to Anadigics, as of January 14, 2016, there were (a) 89,735,630 outstanding Shares, and (b) 912,058 Shares subject to issuance pursuant to options to purchase Shares (“Anadigics Options”) exercisable under the Anadigics Equity Plans (as defined in Section 11 — “The Merger Agreement; Other Agreements — The Merger Agreement — Treatment of Anadigics Options and Anadigics Restricted Stock Unit Awards”). Assuming that all Shares described in clause (b) in the preceding sentence are issued and that (i) no other Shares were or are issued after January 14, 2016 and (ii) no options have been granted or expired after January 14, 2016, the Minimum Condition would be satisfied if at least 45,323,845 Shares are validly tendered and not properly withdrawn prior to the Expiration Date.

The Offer and the withdrawal rights will expire at 11:59 P.M., New York City time, on March 1, 2016 (the “Expiration Date”), unless the Offer is extended or the Merger Agreement has been earlier terminated in accordance with its terms. Under no circumstances will interest be paid with respect to the purchase of Shares pursuant to the Offer, regardless of any extension of the Offer or any delay in making payment for Shares.

After careful consideration, the Board of Directors of Anadigics (the “Anadigics Board”) unanimously (1) determined that the Merger Agreement and the transactions contemplated thereby, including the Offer

and the Merger, are advisable, fair to and in the best interests of Anadigics and its stockholders, (2) approved, and declared advisable, the Merger Agreement, the Offer, the Merger and the transactions contemplated by the Merger Agreement in accordance with the requirements of Delaware law and (3) resolved to recommend that Anadigics’s stockholders accept the Offer and tender their Shares to Purchaser pursuant to the Offer.

A more complete description of the Anadigics Board’s reasons for authorizing and approving the Merger Agreement and the transactions contemplated thereby, including the Offer and the Merger, is set forth in the Schedule 14D-9 that is being filed with the SEC and, together with this Offer to Purchase, the Letter of Transmittal and other related materials, mailed to Anadigics’s stockholders in connection with the Offer. Stockholders should carefully read the information set forth in the Schedule 14D-9 in its entirety.

If you are a record owner of Shares and you tender such Shares directly to the Depositary in accordance with the terms of this Offer, we will not charge you brokerage fees, commissions or, except as set forth in Instruction 6 in the Letter of Transmittal, stock transfer taxes on the sale of Shares pursuant to the Offer. However, if you do not complete and sign the IRS Form W-9 that is enclosed with the Letter of Transmittal (or other applicable form), you may be subject to backup withholding at the applicable statutory rate on the gross proceeds payable to you. See Section 3 — “Procedures for Accepting the Offer and Tendering Shares — Backup Withholding.” Stockholders with Shares held in street name by a broker, dealer, bank, trust company or other nominee should consult with such nominee to determine if they will be charged any service fees or commissions. We will pay all charges and expenses of the Depositary and the Information Agent incurred in connection with the Offer. See Section 17 — “Fees and Expenses.”

The Merger will be governed by Section 251(h) of the DGCL. Accordingly, after the consummation of the Offer and subject to the satisfaction or waiver of the remaining conditions set forth in the Merger Agreement, II-VI, we and Anadigics will cause the Merger to become effective as soon as practicable without a meeting of stockholders of Anadigics in accordance with Section 251(h) of the DGCL. See Section 11 — “The Merger Agreement; Other Agreements — The Merger Agreement — Application of Section 251(h) of the DGCL.”

No appraisal rights are available to the holders of Shares in connection with the Offer. However, if the Merger is consummated, the holders of Shares immediately prior to the Effective Time who (i) did not tender their Shares in the Offer; (ii) follow the procedures set forth in Section 262 of the DGCL and (iii) do not thereafter withdraw their demand for appraisal of such Shares or otherwise lose their appraisal rights, in each case in accordance with the DGCL, will be entitled to have their Shares appraised by the Delaware Court of Chancery and receive payment of the “fair value” of such holder’s Shares, exclusive of any element of value arising from the accomplishment or expectation of the Merger, together with a fair rate of interest, as determined by such court. The “fair value” could be more or less than, or equal to, the Offer Price or the consideration payable in the Merger (which is equivalent in amount to the Offer Price). See Section 16 — “Certain Legal Matters — Appraisal Rights.”

This Offer to Purchase and the Letter of Transmittal contain important information that should be read carefully before any decision is made with respect to the Offer.

Upon the terms and subject to the conditions of the Offer (including, if the Offer is extended or amended, the terms and conditions of such extension or amendment), we will accept for payment and pay for all Shares validly tendered and not properly withdrawn prior to the Expiration Date as permitted under Section 4 — “Withdrawal Rights.”

The Offer is not subject to any financing condition. The Offer is conditioned upon the Minimum Condition, as well as other customary conditions. See Section 15 — “Conditions to the Offer.”

We expressly reserve the right from time to time to waive any of the conditions described in Section 15 — “Conditions to the Offer,” to increase the Offer Price or to make any other changes in the terms and conditions of the Offer, except that we will not, without the prior written consent of Anadigics, (i) decrease the Offer Price, (ii) change the form of consideration payable in the Offer, (iii) decrease the maximum number of Shares sought to be purchased in the Offer, (iv) impose additional conditions to the Offer, (v) amend or modify any of the conditions to the Offer in a manner that adversely affects holders of Shares generally, (vi) amend or modify the Minimum Condition or (vii) extend or otherwise change the Expiration Date in a manner other than as required or permitted by the Merger Agreement.

Pursuant to the Merger Agreement and in accordance with Rule 14d-11 under the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”), but in all instances subject to the provisions of Section 251(h) of the DGCL and our obligation to consummate the Merger as soon as practicable following the consummation of the Offer and satisfaction or waiver of the remaining conditions set forth in the Merger Agreement, we may elect to provide a subsequent offering period (and one or more extensions thereof) following the Expiration Date. Because the Merger will be governed by Section 251(h) of the DGCL, no stockholder vote will be required to consummate the Merger. Following the consummation of the Offer and subject to the satisfaction or waiver of the remaining conditions set forth in the Merger Agreement, we, II-VI and Anadigics will consummate the Merger as soon as practicable. We do not expect there to be a significant period of time between the consummation of the Offer and the consummation of the Merger. If we elect to provide a subsequent offering period, it will be an additional period of time, following the Expiration Date, during which stockholders may tender any Shares not previously tendered into the Offer prior to the Expiration Date (or Shares previously tendered and later withdrawn prior to the Expiration Date) and not withdrawn. If we elect to provide a subsequent offering period, (i) it will remain open for such period or periods as we will specify of neither less than three business days nor more than 20 business days, (ii) Shares may be tendered in the same manner as was applicable to the Offer except that any Shares tendered during such period may not be withdrawn pursuant to Rule 14d-7(a)(2) under the Exchange Act, (iii) we will immediately accept and promptly pay for Shares as they are tendered and (iv) the price per Share will be the same as the Offer Price. For purposes of the Offer as provided under the Exchange Act, a “business day” means any day other than a Saturday, Sunday or a U.S. federal holiday and consists of the time period from 12:01 a.m. through 12:00 midnight, New York City time.

A subsequent offering period, if one is provided, is not an extension of the Offer. If we do elect to provide a subsequent offering period, we will make a public announcement of such election no later than 9:00 a.m., New York City time, on the next business day after the Expiration Date.

The Merger Agreement separately provides that we are required to extend the Offer (i) for successive periods of not more than ten business days each, or such other number of business days as we, II-VI and Anadigics may agree, in order to permit the satisfaction of all conditions that have not been satisfied as of the scheduled Expiration Date (subject to our right to waive any condition to the Offer (other than the Minimum Condition) in accordance with the Merger Agreement), and (ii) for the minimum period required by applicable law or any interpretation or position of the SEC or its staff or the NASDAQ Stock Market, LLC (“NASDAQ”) or its staff, provided that we are not, under any circumstances, obligated to extend the Offer beyond April 14, 2016 (the “End Date”).

If we extend the Offer, are delayed in our acceptance for payment of Shares, are delayed in payment after the time we accept for payment Shares tendered in the Offer (the “Acceptance Time”) or are unable to accept Shares for payment pursuant to the Offer for any reason, then, without prejudice to our rights under the Offer, the Depositary may retain tendered Shares on our behalf, and such Shares may not be withdrawn except to the extent that tendering stockholders are entitled to withdrawal rights as described in this Offer to Purchase under Section 4 — “Withdrawal Rights.” However, our ability to delay the payment for Shares that we have accepted for payment is limited by Rule 14e-1(c) under the Exchange Act, which requires us to promptly pay the consideration offered or return the securities deposited by or on behalf of stockholders promptly after the termination or withdrawal of the Offer.

If we make a material change in the terms of the Offer or the information concerning the Offer or if we waive a material condition of the Offer, we will disseminate additional tender offer materials and extend the Offer if and to the extent required by Rules 14d-4(d)(1), 14d-6(c) and 14e-1 under the Exchange Act and the interpretations thereunder. The minimum period during which an offer must remain open following material changes in the terms of an offer or information concerning an offer, other than a change in price or a change in percentage of securities sought, will depend upon the facts and circumstances, including the relative materiality of the terms or information changes and the appropriate manner of dissemination. In a published release, the SEC has stated that, in its view, an offer should remain open for a minimum of five business days from the date the material change is first published, sent or given to stockholders, and that if material changes are made with respect to information that approaches the significance of price and the percentage of securities sought, a minimum period of 10 business days may be required to allow for adequate dissemination to stockholders and investor response. In accordance with the foregoing view of the SEC and applicable law, if, prior to the Expiration Date, and subject to the limitations of the Merger Agreement, we change the number of Shares being sought or the consideration offered pursuant to the Offer, and if the Offer is scheduled to expire at any time earlier than the 10th business day from the date that notice of such change is first published, sent or given to stockholders, the Offer will be extended at least until the expiration of such 10th business day.

If, prior to the Expiration Date, we increase the consideration being paid for Shares, such increased consideration will be paid to all stockholders whose Shares are purchased in the Offer, whether or not such Shares were tendered before the announcement of such increase in consideration.

Any extension, delay, termination, waiver or amendment of the Offer will be followed promptly by public announcement thereof, such announcement in the case of an extension to be made no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled Expiration Date. Subject to applicable law (including Rules 14d-4(d), 14d-6(c) and 14e-1 under the Exchange Act, which require that material changes be promptly disseminated to stockholders in a manner reasonably designed to inform them of such changes) and without limiting the manner in which we may choose to make any public announcement, we will have no obligation to publish, advertise or otherwise communicate any such public announcement other than by issuing a press release to a national news service.

Anadigics has provided us with its stockholder list and security position listings for the purpose of disseminating the Offer to holders of Shares. This Offer to Purchase and the Letter of Transmittal will be mailed to record holders of Shares whose names appear on Anadigics’s stockholder list and will be furnished, for subsequent transmittal to beneficial owners of Shares, to brokers, dealers, commercial banks, trust companies and other nominees whose names, or the names of whose nominees, appear on the stockholder list or, if applicable, who are listed as participants in a clearing agency’s security position listing.

Upon the terms and subject to the conditions of the Offer (including, if the Offer is extended or amended, the terms and conditions of any such extension or amendment), we will promptly accept for payment and promptly thereafter pay for all Shares validly tendered and not properly withdrawn prior to the Expiration Date pursuant to the Offer.

In all cases, payment for Shares accepted for payment pursuant to the Offer will be made only after timely receipt by the Depositary of:

Accordingly, tendering stockholders may be paid at different times depending upon when Share Certificates or Book-Entry Confirmations with respect to their Shares are actually received by the Depositary.

For purposes of the Offer, we will be deemed to have accepted for payment, and thereby purchased, Shares validly tendered and not properly withdrawn, if and when we give oral or written notice to the Depositary of our acceptance for payment of such Shares pursuant to the Offer. Upon the terms and subject to the conditions to the Offer, payment for Shares accepted for payment pursuant to the Offer will be made by deposit of the Offer Price therefor with the Depositary, which will act as agent for tendering stockholders for the purpose of receiving payments from us and transmitting such payments to tendering stockholders of record whose Shares have been accepted for payment. If, for any reason whatsoever, acceptance for payment of any Shares tendered pursuant to the Offer is delayed, or we are unable to accept for payment Shares tendered pursuant to the Offer, then, without prejudice to our rights under the Offer, the Depositary may, nevertheless, on our behalf, retain tendered Shares, and such Shares may not be withdrawn, except to the extent that the tendering stockholders are entitled to withdrawal rights as described in Section 4 — “Withdrawal Rights” and as otherwise required by Rule 14e-1(c) under the Exchange Act.

Under no circumstances will interest with respect to the Shares purchased pursuant to the Offer be paid, regardless of any extension of the Offer or delay in making such payment.

All questions as to the validity, form, eligibility (including time of receipt) and acceptance for payment of any tender of Shares will be determined by us in our sole discretion. We reserve the absolute right to reject any and all tenders determined by us not to be in proper form or the acceptance for payment of which may, in the opinion of our counsel, be unlawful.

Shares tendered by a Notice of Guaranteed Delivery will not be deemed validly tendered for purposes of satisfying the Minimum Condition unless and until Shares underlying such Notice of Guaranteed Delivery are delivered to the Depositary or unless otherwise mutually agreed by us and Anadigics.

If any tendered Shares are not accepted for payment for any reason pursuant to the terms and conditions of the Offer, or if Share Certificates are submitted evidencing more Shares than are tendered, Share Certificates evidencing unpurchased or untendered Shares will be returned, without expense, to the tendering stockholder (or, in the case of Shares tendered by book-entry transfer into the Depositary’s account at the Book-Entry Transfer Facility pursuant to the procedure set forth in Section 3 — “Procedures for Accepting the Offer and Tendering Shares,” such Shares will be credited to an account maintained at the Book-Entry Transfer Facility), in each case, promptly following the expiration or termination of the Offer.

Valid Tender of Shares. No alternative, conditional or contingent tenders will be accepted. In order for a Anadigics stockholder to validly tender Shares pursuant to the Offer, the stockholder must follow one of the following procedures:

The term “Agent’s Message” means a message transmitted by the Book-Entry Transfer Facility to, and received by, the Depositary and forming a part of a Book-Entry Confirmation that states that the Book-Entry Transfer Facility has received an express acknowledgment from the participant in the Book-Entry Transfer Facility tendering the Shares that are the subject of such Book-Entry Confirmation, that such participant has received and agrees to be bound by the terms of the Letter of Transmittal and that we may enforce such agreement against such participant.

Book-Entry Transfer. The Depositary will establish an account with respect to the Shares at the Book-Entry Transfer Facility for purposes of the Offer within two business days after the date of this Offer to Purchase. Any financial institution that is a participant in the system of the Book-Entry Transfer Facility may make a book-entry delivery of Shares by causing the Book-Entry Transfer Facility to transfer such Shares into the Depositary’s account at the Book-Entry Transfer Facility in accordance with the Book-Entry Transfer Facility’s procedures for such transfer. However, although delivery of Shares may be effected through book-entry transfer at the Book-Entry Transfer Facility, either a properly completed and duly executed Letter of Transmittal, together with any required signature guarantees, or an Agent’s Message and any other required documents (for example, in certain circumstances, a completed IRS Form W-9 that is included in the Letter of Transmittal) must, in any case, be received by the Depositary at one of its addresses set forth on the back cover of this Offer to Purchase prior to the Expiration Date, or the tendering stockholder must comply with the guaranteed delivery procedure described below. Delivery of documents to the Book-Entry Transfer Facility does not constitute delivery to the Depositary.

Signature Guarantees. No signature guarantee is required on the Letter of Transmittal if:

In all other cases, all signatures on a Letter of Transmittal must be guaranteed by an Eligible Institution. See Instructions 1 and 5 of the Letter of Transmittal. If a Share Certificate is registered in the name of a person or persons other than the signer of the Letter of Transmittal, or if payment is to be made or delivered to, or a Share Certificate not accepted for payment or not tendered is to be issued in the name of or returned to, a person other than the registered holder(s), then the Share Certificate must be endorsed or accompanied by appropriate duly executed stock powers, in either case signed exactly as the name(s) of the registered holder(s) appears on the Share Certificate, with the signature(s) on such Share Certificate or stock powers guaranteed by an Eligible Institution as provided in the Letter of Transmittal. See Instructions 1 and 5 of the Letter of Transmittal.

Guaranteed Delivery. If a stockholder desires to tender Shares pursuant to the Offer and the Share Certificates evidencing such stockholder’s Shares are not immediately available or such stockholder cannot deliver the Share Certificates and all other required documents to the Depositary prior to the Expiration Date, or such stockholder cannot complete the procedure for delivery by book-entry transfer on a timely basis, such Shares may nevertheless be tendered; provided that all of the following conditions are satisfied:

A Notice of Guaranteed Delivery may be delivered by overnight courier or mailed to the Depositary and must include a guarantee by an Eligible Institution in the form set forth in the form of Notice of Guaranteed Delivery made available by us. In the case of Shares held through the Book-Entry Transfer Facility, the Notice of Guaranteed Delivery must be delivered to the Depositary by a participant by means of the confirmation system of the Book-Entry Transfer Facility.

Shares tendered by a Notice of Guaranteed Delivery will not be deemed validly tendered for purposes of satisfying the Minimum Condition unless and until Shares underlying such Notice of Guaranteed Delivery are delivered to the Depositary unless otherwise mutually agreed by us and Anadigics.

The method of delivery of Shares, the Letter of Transmittal and all other required documents, including delivery through the Book-Entry Transfer Facility, is at the election and risk of the tendering stockholder. Shares will be deemed delivered only when actually received by the Depositary (including, in the case of a book-entry transfer, by Book-Entry Confirmation). If delivery is by mail, then registered mail with return receipt requested, properly insured, is recommended. In all cases, sufficient time should be allowed to ensure timely delivery.

The tender of Shares pursuant to any one of the procedures described above will constitute the tendering stockholder’s acceptance of the terms and conditions of the Offer, as well as the tendering stockholder’s

representation and warranty that such stockholder has the full power and authority to tender and assign the Shares tendered, as specified in the Letter of Transmittal, and that when the Acceptance Time occurs, we will acquire good and unencumbered title, free and clear of all liens, restrictions, charges and encumbrances and not subject to any adverse claims. Our acceptance for payment of Shares tendered pursuant to the Offer will constitute a binding agreement between the tendering stockholder and us upon the terms and subject to the conditions to the Offer.

Determination of Validity. All questions as to the validity, form, eligibility (including time of receipt) and acceptance for payment of any tender of Shares will be determined by us in our sole discretion. We reserve the absolute right to reject any and all tenders we determine not to be in proper form or the acceptance for payment of which may, in the opinion of our counsel, be unlawful. We also reserve the absolute right to waive any defect or irregularity in the tender of any Shares of any particular stockholder, whether or not similar defects or irregularities are waived in the case of other stockholders. No tender of Shares will be deemed to have been validly made until all defects and irregularities have been cured or waived to our satisfaction. None of us, the Depositary, the Information Agent or any other person will be under any duty to give notification of any defects or irregularities in tenders or incur any liability for failure to give any such notification. Our interpretation of the terms and conditions of the Offer (including the Letter of Transmittal and the instructions thereto) will be determined by us in our sole discretion.

Appointment as Proxy. By executing the Letter of Transmittal (or taking action resulting in the delivery of an Agent’s Message) as set forth above, unless Shares relating to such Letter of Transmittal or Agent’s Message are properly withdrawn pursuant to the Offer, the tendering stockholder will irrevocably appoint our designees, and each of them, as such stockholder’s attorneys-in-fact and proxies in the manner set forth in the Letter of Transmittal, each with full power of substitution, to the full extent of such stockholder’s rights with respect to the Shares tendered by such stockholder and accepted for payment by us and with respect to any and all other Shares or other securities or rights issued or issuable in respect of such Shares. All such proxies will be considered coupled with an interest in the tendered Shares. Such appointment will be effective if and when, and only to the extent that, we accept such Shares for payment pursuant to the Offer. Upon such appointment, all prior powers of attorney, proxies and consents given by such stockholder with respect to such Shares or other securities or rights will, without further action, be revoked and no subsequent powers of attorney, proxies, consents or revocations may be given by such stockholder (and, if given, will not be deemed effective) with respect thereto. Each of our designees will thereby be empowered to exercise all voting and other rights with respect to such Shares and other securities or rights, including in respect of any annual, special or adjourned meeting of Anadigics’s stockholders or otherwise, as such designee in its sole discretion deems proper. We reserve the right to require that, in order for Shares to be deemed validly tendered, immediately upon the occurrence of the Acceptance Time, we must be able to exercise full voting, consent and other rights with respect to such Shares and other securities and rights, including voting at any meeting of stockholders.

The foregoing powers of attorney and proxies are effective only upon acceptance for payment of Shares pursuant to the Offer. The Offer does not constitute a solicitation of proxies, absent a purchase of Shares, for any meeting of Anadigics’s stockholders.

Anadigics Options and Anadigics Restricted Stock Unit Awards. The Offer is made only for outstanding Shares and is not made for any Anadigics Options or Anadigics Restricted Stock Unit Awards (as defined in Section 11 — “The Merger Agreement; Other Agreements — The Merger Agreement — Treatment of Anadigics Options and Anadigics Restricted Stock Unit Awards”). See Section 11 — “The Merger Agreement; Other Agreements — The Merger Agreement — Treatment of Anadigics Options and Anadigics Restricted Stock Unit Awards” for a description of the treatment of the Anadigics Options and Anadigics Restricted Stock Unit Awards.

Backup Withholding. To prevent federal “backup withholding” with respect to payment of the Offer Price of Shares purchased pursuant to the Offer, each stockholder (including any stockholder that tenders Shares into the

Offer pursuant to the book-entry transfer procedures described above in this Section 3) must provide the Depositary with its correct taxpayer identification number and certify that it is not subject to backup withholding by completing the IRS Form W-9 that is included in the Letter of Transmittal or by otherwise certifying such stockholder’s exemption from backup withholding. See Instruction 8 set forth in the Letter of Transmittal and Section 5 — “Certain Material U.S. Federal Income Tax Consequences of the Offer and the Merger” of this Offer to Purchase for a more detailed discussion of backup withholding.

Except as otherwise provided in this Section 4, tenders of Shares made pursuant to the Offer are irrevocable. Shares tendered pursuant to the Offer may be withdrawn at any time prior to the Expiration Date. Thereafter, tenders of Shares are irrevocable, except that they may also be withdrawn after April 2, 2016, which is the 60th day from the commencement of the Offer, unless such Shares have already been accepted for payment by us pursuant to the Offer.

For a withdrawal to be proper and effective, a written notice of withdrawal must be timely received by the Depositary at one of its addresses set forth on the back cover page of this Offer to Purchase. Any such notice of withdrawal must specify the name of the person who tendered the Shares to be withdrawn, the number of Shares to be withdrawn and the name of the registered holder of such Shares, if different from that of the person who tendered such Shares. If Share Certificates evidencing Shares to be withdrawn have been delivered or otherwise identified to the Depositary, then, prior to the physical release of such Share Certificates, the serial numbers shown on such Share Certificates must be submitted to the Depositary and the signature(s) on the notice of withdrawal must be guaranteed by an Eligible Institution, unless such Shares have been tendered for the account of an Eligible Institution. If Shares have been tendered pursuant to the procedure for book-entry transfer as set forth in Section 3 — “Procedures for Accepting the Offer and Tendering Shares — Book-Entry Transfer,” any notice of withdrawal must also specify the name and number of the account at the Book-Entry Transfer Facility to be credited with the withdrawn Shares.

If we extend the Offer, are delayed in our acceptance for payment of Shares or are unable to accept Shares for payment pursuant to the Offer for any reason, then, without prejudice to our rights under the Offer, the Depositary may, nevertheless, on our behalf, retain tendered Shares, and such Shares may not be withdrawn except to the extent that tendering stockholders are entitled to withdrawal rights as described in this Section 4 and as otherwise required by Rule 14e-1(c) under the Exchange Act.

Withdrawals of tendered Shares may not be rescinded, and any Shares properly withdrawn will thereafter be deemed not to have been validly tendered for purposes of the Offer. However, Shares that have been properly withdrawn may be re-tendered at any time prior to the Expiration Date by following one of the procedures described in Section 3 — “Procedures for Accepting the Offer and Tendering Shares — Valid Tender of Shares.”

Shares previously tendered into the Offer and accepted for payment, or if we elect to provide a subsequent offering period, Shares tendered in such subsequent offering period (as described in more detail in Section 1 — “Terms of the Offer”), may not be withdrawn.

All questions as to the form and validity (including time of receipt) of any notice of withdrawal will be determined by us in our sole discretion. We also reserve the absolute right to waive any defect or irregularity in the withdrawal of Shares by any stockholder, regardless of whether or not similar defects or irregularities are waived in the case of other stockholders. None of us, the Depositary, the Information Agent or any other person will be under any duty to give notification of any defects or irregularities in any notice of withdrawal or incur any liability for failure to give any such notification.

5. Certain Material U.S. Federal Income Tax Consequences of the Offer and the Merger.

The following is a summary of certain material U.S. federal income tax consequences of the Offer and the Merger to holders whose Shares are purchased pursuant to the Offer or whose Shares are converted into the right to receive cash in the Merger (or pursuant to the exercise of appraisal rights in accordance with Delaware law). This summary is based on the Internal Revenue Code of 1986, as amended, applicable treasury regulations and administrative and judicial interpretations thereunder, each as in effect as of the date hereof, all of which may change, possibly with retroactive effect. This summary is not a comprehensive description of all U.S. federal income tax consequences of the Offer and the Merger that may be relevant to particular holders in light of their individual circumstances. The discussion applies only to holders that hold their Shares as capital assets, and may not apply to Shares received pursuant to the exercise of employee stock options or otherwise as compensation, Shares held as part of a “straddle,” “hedge,” “conversion transaction,” constructive sale or other integrated transaction, holders that purchase or sell Shares as part of a wash sale for tax purposes, holders in special tax situations (such as dealers in securities or currencies, traders in securities that elect to use a mark-to-market method of accounting for their securities holdings, banks, insurance companies, tax-exempt organizations, U.S. expatriates, “controlled foreign corporations” or “passive foreign investment companies”), or United States Holders (as defined below) whose functional currency is not the U.S. dollar. This discussion does not address any aspect of U.S. federal gift or estate tax, or state, local or foreign taxation.

If a partnership (or other entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds Shares, the tax treatment of a partner in the partnership generally will depend on the status of the partner and the tax treatment of the partnership. Accordingly, partnerships that hold Shares and partners in such partnerships should consult their tax advisors with regard to the U.S. federal income tax consequences of exchanging Shares pursuant to the Offer or the Merger.

THE MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES SET FORTH BELOW ARE BASED ON CURRENT LAW. BECAUSE INDIVIDUAL CIRCUMSTANCES MAY DIFFER, EACH HOLDER SHOULD CONSULT SUCH HOLDER’S OWN TAX ADVISOR TO DETERMINE THE APPLICABILITY OF THE RULES DISCUSSED BELOW TO SUCH HOLDER AND THE PARTICULAR TAX EFFECTS OF THE OFFER AND THE MERGER TO SUCH HOLDER, INCLUDING THE APPLICATION AND EFFECT OF U.S. FEDERAL ESTATE AND GIFT, STATE, LOCAL AND OTHER TAX LAWS.

United States Holders. For purposes of this discussion, the term “United States Holder” means a beneficial owner of Shares that is, for U.S. federal income tax purposes:

The receipt of cash for Shares pursuant to the Offer or the Merger (or pursuant to the exercise of appraisal rights) will be a taxable transaction for U.S. federal income tax purposes. In general, a United States Holder will recognize gain or loss in an amount equal to the difference between the amount of cash received by such United States Holder pursuant to the Offer or converted into the right to receive cash in the Merger (or appraised in an appraisal proceeding by the Delaware Court of Chancery) and such United States Holder’s adjusted federal income tax basis in such Shares therein. Gain or loss must be determined separately for each block of Shares (i.e., Shares acquired at the same cost in a single transaction) sold pursuant to the Offer or converted into the

right to receive cash in the Merger. Such gain or loss will be capital gain or loss (other than, with respect to the exercise of appraisal rights, amounts, if any, that are or are deemed to be interest for federal income tax purposes, which amounts will be taxed as ordinary income) and will be long-term capital gain or loss if, on the date of sale (or, if applicable, the date of the Merger), such Shares were held for more than one year. Long-term capital gains recognized by an individual generally will be taxed at preferential rates. Capital losses may be subject to limits on deductibility.

An additional 3.8% tax is imposed on the “net investment income” of certain United States Holders. Among other items, “net investment income” generally includes gain from the disposition of the Shares and interest income, less certain deductions. Each United States Holder that is an individual, estate or trust should consult such United States Holder’s tax advisor with respect to the potential application of this additional tax.

Non-United States Holders. For purposes of this discussion, the term “Non-United States Holder” means a beneficial owner of Shares that is not a United States Holder.

In general, a Non-United States Holder will not be subject to U.S. federal income tax on gain recognized on Shares sold pursuant to the Offer or converted into the right to receive cash in the Merger (or appraised in an appraisal proceeding by the Delaware Court of Chancery) unless:

“Effectively connected” gains that are recognized by a corporate Non-United States Holder also may be subject, under certain circumstances, to an additional “branch profits tax” at a 30% rate or at a lower rate if such holder is eligible for the benefits of an income tax treaty that provides for a lower rate.

Information Reporting and Backup Withholding. Payments made to a noncorporate United States Holder in connection with the Offer or the Merger generally will be subject to information reporting and may be subject to “backup withholding.” See Section 3 — “Procedures for Accepting the Offer and Tendering Shares — Backup Withholding” of this Offer to Purchase.

Backup withholding generally applies if a United States Holder (i) fails to provide an accurate taxpayer identification number or (ii) in certain circumstances, fails to comply with applicable certification requirements. A Non-United States Holder generally will be exempt from information reporting and backup withholding if it certifies on an appropriate IRS Form W-8 that it is not a U.S. person, or otherwise establishes an exemption in a manner satisfactory to the Depositary.

Backup withholding is not an additional tax and may be refunded by the Internal Revenue Service to the extent it results in an overpayment of tax. Certain persons generally are entitled to exemption from information reporting and backup withholding, including corporations. Certain penalties apply for failure to provide correct information and for failure to include reportable payments in income. Each holder should consult with his or her own tax advisor as to his or her qualification for exemption from backup withholding and the procedure for obtaining such exemption. Tendering United States Holders may be able to prevent backup withholding by completing the IRS Form W-9 that is included in the Letter of Transmittal or, in the case of Non-United States Holders, an IRS Form W-8BEN.

The Shares are listed and principally traded on NASDAQ under the symbol “ANAD.” The following table sets forth the high and low sales prices per Share for the periods indicated as reported on NASDAQ based on published financial sources:

On January 15, 2016, the last full trading day before the execution of the Merger Agreement and the Offer was announced, the closing price of the Shares on NASDAQ was $0.68 per Share. On February 1, 2016, the last full day of trading before the commencement of the Offer, the closing price of the Shares on NASDAQ was $0.69 per Share.

Available Information. Pursuant to Rule 14d-3 under the Exchange Act, we and II-VI have filed with the SEC a Tender Offer Statement on Schedule TO (as amended, which we refer to as the “Schedule TO”), of which this Offer to Purchase forms a part, and exhibits to the Schedule TO and such documents are available to the public over the Internet at the SEC’s website at www.sec.gov.

We estimate that we will need approximately $61 million to purchase all Shares pursuant to the Offer and to consummate the Merger (which includes, among other things, payment to acquire the remaining Shares in the Merger and payment in respect of Anadigics Options and Anadigics Restricted Stock Unit Awards (in each case as defined in Section 11 — “The Merger Agreement; Other Agreements — The Merger Agreement — Treatment of Anadigics Options and Anadigics Restricted Stock Unit Awards”), and to pay related fees and expenses. II-VI will provide us with sufficient funds to purchase all Shares validly tendered in the Offer, and will provide funding to consummate the Merger and to pay related transaction fees and expenses. II-VI expects to fund such cash requirements from its cash on hand and available borrowings under its credit facility. There are no material conditions to this funding, and there are no alternative financing arrangements or alternative financing plans that would apply in the event the above funding falls through. The Offer is not conditioned upon obtaining financing.

II-VI’s Second Amended and Restated Credit Agreement (the “Credit Facility”), among II-VI, each of the Guarantors party thereto, the Lenders party thereto, and PNC Bank, National Association, as administrative agent, provides for a revolving credit facility of $225 million, as well as a $100 million term loan (the “Term Loan”). The Term Loan is being re-paid in consecutive quarterly principal payments on the first business day of each January, April, July and October, with the first payment having commenced on October 1, 2013, as follows: (i) twenty consecutive quarterly installments of $5.0 million and (ii) a final installment of all remaining principal due and payable on the maturity date. Amounts borrowed under the revolving credit facility are due and payable on the maturity date. The Credit Facility is unsecured, but is guaranteed by each existing and subsequently acquired or organized wholly-owned domestic subsidiary of II-VI. II-VI has the option to request an increase to the size of the Credit Facility in an aggregate additional amount not to exceed $100 million. The Credit Facility has a five-year term through September 2018 and has an interest rate of either a Base Rate Option or a Euro-Rate Option, plus an Applicable Margin, as defined in the agreement governing the Credit Facility. If the Base Rate Option is selected for a borrowing, the Applicable Margin is 0.00% to 0.75% and if the Euro-Rate Option is selected for a borrowing, the Applicable Margin is 0.75% to 1.75%. The Applicable Margin is based on II-VI’s ratio of consolidated indebtedness to consolidated EBITDA. Additionally, the facility is subject to certain covenants, including those relating to minimum interest coverage and maximum leverage ratios. II-VI currently plans to repay amounts borrowed under the Credit Facility in accordance with the terms of the Credit Facility and, consistent with past practice, will evaluate opportunities to prepay borrowed amounts from time to time.

10. Background of the Offer; Past Contacts, Transactions, Negotiations and Agreements with Anadigics.

The following is a description of key contacts between representatives of II-VI or Purchaser and representatives of Anadigics that resulted in execution of the Merger Agreement. For a review of Anadigics’s additional activities relating to the background of the transaction with II-VI and Purchaser, please refer to Anadigics’s Schedule 14D-9 filed with the SEC and mailed to Anadigics’s stockholders in accordance with the terms of the Securities Exchange Act of 1934, as amended.

II-VI Incorporated regularly evaluates its supply chain and, as a result, expands and qualifies new supply chain partners. In this regard, a manager of one of II-VI’s subsidiaries first contacted Anadigics in May 2015 to inquire about the wafer fabrication foundry services that Anadigics could provide. After several conversations about the subject, a mutual confidentiality and non-disclosure agreement was entered into between II-VI and Anadigics effective as of October 23, 2015, to facilitate discussions regarding product development issues, and a meeting was held on October 25, 2015 at Anadigics’s facility in Warren, New Jersey between Dr. Vincent D. Mattera Jr., the President of II-VI, and Dr. David J. Cheskis, the Director of Optical Products of Anadigics, where the wafer fabrication facilities and other capabilities of Anadigics were discussed as they related to the potential development and fabrication services needed by II-VI and certain of its customers.

Additional details regarding the technical capabilities of Anadigics and requirements of II-VI were shared between the parties, and a subsequent meeting was held on November 11, 2015 at Anadigics’s offices in Warren, New Jersey among Mr. Francis J. Kramer, the Chairman and CEO of II-VI, Dr. Mattera, Mr. Ronald Michels, the CEO of Anadigics, and Dr. Cheskis. At that meeting, the parties discussed further Anadigics’s capabilities and the concerns of II-VI regarding the financial condition of Anadigics as it related to supply chain stability.

Following that meeting and also on November 11, 2015, Anadigics entered into an Agreement and Plan of Merger (the “Aloha Merger Agreement”) with Aloha Holding Company, Inc. (“Aloha”), an affiliate of GaAs Labs, LLC (“GaAs Labs”), and Aloha Acquisition Sub, Inc. (“Aloha Sub”), whereby Aloha would acquire Anadigics pursuant to a tender offer for all of the Shares conducted by Aloha Sub at a price per share of $0.35, without interest (the “Aloha Offer”), at the conclusion of which Aloha Sub would be merged with and into Anadigics and Anadigics would become a wholly-owned subsidiary of Aloha and an affiliate of GaAs Labs. The Aloha Merger Agreement provided for, among other things, a “go-shop” period through December 6, 2015 pursuant to which Anadigics and its representatives were permitted to solicit third parties to discuss the potential acquisition of Anadigics at a price and terms that would be superior to the price and terms of the Aloha Merger Agreement, and to make available due diligence information regarding Anadigics and its business.

On November 12, 2015, Anadigics issued a press release announcing the execution of the Aloha Merger Agreement. After reading that press release and a copy of the Aloha Merger Agreement, representatives from II-VI contacted Anadigics to express their interest in learning more about Anadigics and the go-shop process. In that regard, on November 16, 2015, II-VI and Anadigics executed a Mutual Non-Disclosure Agreement regarding the business, assets, operations, management team, and personnel of II-VI, and on or about November 16, 2015, II-VI was granted access to Anadigics’s online data room.

On or about November 20, 2015, II-VI retained Wunderlich Securities, Inc. (“Wunderlich”) as its financial advisor.

From November 20, 2015 onward, II-VI and its representatives have continued to evaluate the information in Anadigics’s data room, conducted due diligence telephone calls with representatives from Anadigics as well as their financial advisor, Needham & Co. (“Needham”), and also continued certain discussions regarding the ability of Anadigics to provide wafer fabrication services.

On November 23-25, 2015, representatives from II-VI were given a tour of Anadigics’s fabrication facility in Warren, New Jersey, and participated, in conjunction with its financial and legal advisors, either in person on by telephone in on-site management presentations and in discussions with various members of Anadigics’s management team held at Anadigics’s offices in Warren, New Jersey.

On November 29, 2015, representatives of II-VI, Wunderlich, and II-VI’s legal counsel held a telephonic conference with representatives of Anadigics, Anadigics’s legal counsel and Needham to discuss business and legal due diligence issues.

On December 1, 2015, the board of directors of II-VI (the “II-VI Board”) met to discuss the potential acquisition of Anadigics. Later that day Mr. Kramer and Dr. Mattera met with Mr. Michels. During that meeting, the parties discussed in more detail Anadigic’s business and II-VI’s interest in submitting a proposal to acquire Anadigics.

On December 3, 2015, the II-VI Board met to discuss in more detail the potential acquisition of Anadigics and authorized management of II-VI to make a proposal for that acquisition, and on December 5, 2015, Wunderlich, on behalf of II-VI, submitted a non-binding offer letter to Anadigics and Needham. The offer letter described II-VI’s interest in entering into a merger agreement substantially similar to the Aloha Merger Agreement, but at a price per share of $0.45 in cash.

On December 7, 2015, Anadigics issued a press release stating that the go-shop period had come to an end as provided for in the Aloha Merger Agreement, that Anadigics had received offers from two different parties by the December 6, 2015 go-shop deadline, and that both parties would be deemed Excluded Parties as that term was defined in the Aloha Merger Agreement.

On December 9, 2015, Wunderlich, on behalf of II-VI and in response to a request from Anadigics, submitted a non-binding, unsigned form of merger agreement, complete with exhibits and schedules, to Anadigics and Needham. That form of merger agreement was substantially similar to the Aloha Merger Agreement, but provided for a purchase price per share of $0.45 in cash and the payment by II-VI on behalf of Anadigics of the termination fee to be due to Aloha under the Aloha Merger Agreement.

On December 10, 2015, the II-VI Board met to consider information about Anadigics, and authorized management of II-VI to continue with making a proposal for Anadigics.

On December 11, 2015, Needham contacted Wunderlich to advise them that (i) II-VI’s $0.45 per share offer was not the highest offer Anadigics had received, and (ii) only one offer would be designated a Superior Offer as defined in the Aloha Merger Agreement and submitted to Aloha as part of the go-shop process. Following that conversation, Wunderlich, on behalf of II-VI, submitted a non-binding, unsigned merger agreement, complete with exhibits and schedules, to Anadigics and Needham. This draft of the merger agreement was substantially similar to the prior form of merger agreement, but the price per share was increased to $0.48 in cash and it reflected a termination fee of $600,000, coupled with an obligation to repay II-VI the termination fee to be paid to Aloha under the Aloha Merger Agreement. Also on December 11, 2015, Anadigics and II-VI entered into an amendment to the Non-Disclosure Agreement regarding certain procedures relating to selected customer and product information.

On December 12, 2015, Needham contacted Wunderlich to advise that in order for the merger agreement proposed by II-VI to be considered a Superior Offer as defined in the Aloha Merger Agreement, the merger agreement proposed by II-VI would need to be signed by II-VI and be a binding offer acceptable by Anadigics. On December 15, 2015, the II-VI Board met to discuss the status of the II-VI proposal and the potential transaction, and authorized management of II-VI to make an additional proposal for Anadigics. Later that day, Wunderlich, on behalf of II-VI, submitted a signed draft merger agreement, complete with exhibits and schedules, to Anadigics and Needham. This version of merger agreement would become binding in the event that

(i) Aloha did not exercise its matching right under the Aloha Merger Agreement, and (ii) the merger agreement was countersigned by Anadigics within six business days. The offer price remained at $0.48 per share.

On December 21, 2015, Needham contacted Wunderlich to advise that Aloha intended to exercise its matching right under the Aloha Merger Agreement and had submitted to Anadigics a proposed amendment to the Aloha Merger Agreement reflecting a cash purchase price of $0.48 per share.

On December 22, 2015, the II-VI Board met to discuss further the status of the proposed transaction, and authorized management of II-VI to continue with the proposals to acquire Anadigics. Later that day, Wunderlich, on behalf of II-VI, submitted a signed draft merger agreement, substantially identical to the prior version and complete with exhibits and schedules, to Anadigics and Needham reflecting an increased cash purchase price of $0.54 per share. The merger agreement would become binding in the event that (i) Aloha did not exercise its matching right under the Aloha Merger Agreement, and (ii) the merger agreement was countersigned by Anadigics within three business days. On December 28, 2015, Needham contacted Wunderlich to advise that Aloha intended to exercise its matching right under the Aloha Merger Agreement and had submitted to Anadigics a proposed amendment to the Aloha Merger Agreement reflecting a purchase price of $0.54 per share and an increased termination fee of $2.5 million.

On December 29, 2015, Wunderlich, on behalf of II-VI, submitted a signed draft merger agreement, substantially identical to the preceding version and complete with exhibits and schedules, to Anadigics and Needham reflecting an increased cash purchase price of $0.58 per share and an increased termination fee of $1.2 million. The merger agreement would become binding in the event that (i) Aloha did not exercise its matching right under the Aloha Merger Agreement, and (ii) the merger agreement was countersigned by Anadigics within four business days. On January 4, 2016, Needham contacted Wunderlich to advise that Aloha intended to exercise its matching right under the Aloha Merger Agreement and had submitted to Anadigics a proposed amendment to the Aloha Merger Agreement reflecting a purchase price of $0.58 per share and the same increased termination fee of $2.5 million.

On January 4, 2016, the II-VI Board met to consider the potential transaction with Anadigics and related issues, and authorized management of II-VI to continue to make proposals for the acquisition of Anadigics. To that end, on January 5, 2016, Wunderlich, on behalf of II-VI, submitted a signed draft merger agreement, substantially identical to II-VI’s preceding version and complete with exhibits and schedules, to Anadigics and Needham reflecting an increased cash purchase price of $0.62 per share. The merger agreement would become binding in the event that (i) Aloha did not exercise its matching right under the Aloha Merger Agreement, and (ii) the merger agreement was countersigned by Anadigics within four business days. As with prior proposals, on or about January 7, 2016, Needham contacted Wunderlich to advise that Aloha intended to exercise its matching right under the Aloha Merger Agreement and had submitted to Anadigics a proposed further amendment to the Aloha Merger Agreement reflecting a purchase price of $0.62 per share and the same increased termination fee of $2.5 million.

On January 7, 2016, Dr. Mattera met with Mr. Michels for dinner, and they discussed various matters regarding the financial and operating condition of Anadigics and certain product development and production issues.

After further discussion with management of II-VI, on January 11, 2016, Wunderlich, on behalf of II-VI, submitted a signed draft merger agreement, substantially identical to II-VI’s preceding version and complete with exhibits and schedules, to Anadigics and Needham reflecting an increased cash purchase price of $0.66 per share. The merger agreement would become binding in the event that (i) Aloha did not exercise its matching right under the Aloha Merger Agreement, and (ii) the merger agreement was countersigned by Anadigics within four business days.

On January 12, 2016, Dr. Mattera met with Mr. Michels and Mr. Terrence Gallagher, the Chief Financial Officer of Anadigics, at Anadigics’s offices in Warren, New Jersey. At that meeting they discussed issues regarding product development, capabilities, and supply. Discussions and development activities among representatives of II-VI and Anadigics have continued since then regarding product development, supply, and testing.

After the close of business on January 14, 2016, Needham informed Wunderlich that Aloha had indicated that it did not intend to submit a matching proposal. On the morning of January 15, 2016, the II-VI board met to discuss the status of the proposals and related issues, and approved the execution and acceptance of the Merger Agreement, the commencement of the Offer, and the consummation of the Merger Agreement and the transactions contemplated therein. In the absence of a match by Aloha, later on January 15, 2016 the board of directors of Anadigics met to discuss the proposed Merger Agreement and unanimously approved the Merger Agreement, the Offer, and the Merger and unanimously voted to recommend to the stockholders of Anadigics to tender their shares of Anadigics stock in the Offer at a price per share of $0.66 in cash, without interest. Anadigics subsequently executed the Merger Agreement on January 15, 2016 after the close of trading on NASDAQ, and on January 19, 2016, prior to the opening of trading on NASDAQ, both II-VI and Anadigics issued press releases announcing the execution of the Merger Agreement and II-VI’s intention to commence the Offer at price of $0.66 per share in cash, without interest.

The following is a summary of certain provisions of the Merger Agreement. This summary does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, a copy of which is filed as Exhibit (d)(1) to the Schedule TO, which is incorporated herein by reference. Copies of the Merger Agreement and the Schedule TO, and any other filings that we make with the SEC with respect to the Offer or the Merger, may be obtained in the manner set forth in Section 8 — “Certain Information Concerning Purchaser and II-VI — Available Information.” Stockholders and other interested parties should read the Merger Agreement for a more complete description of the provisions summarized below.

The Merger Agreement is included to provide you with information regarding its terms. Factual disclosures about II-VI, us and Anadigics or any of their respective affiliates contained in this Offer to Purchase or in their respective public reports filed with the SEC, as applicable, may supplement, update or modify the factual disclosures about II-VI, us and Anadigics or any of their respective affiliates contained in the Merger Agreement. The representations, warranties and covenants made in the Merger Agreement by II-VI, us and Anadigics were qualified and subject to important limitations agreed to by II-VI, us and Anadigics in connection with negotiating the terms of the Merger Agreement. In particular, in your review of the representations and warranties contained in the Merger Agreement and described in this summary, it is important to bear in mind that the representations and warranties were negotiated with the principal purposes of establishing the circumstances in which a party to the Merger Agreement may have the right not to consummate the Offer or the Merger if the representations and warranties of the other party prove to be untrue, and allocating risk between the parties to the Merger Agreement, rather than establishing matters as facts. The representations and warranties may also be subject to a contractual standard of materiality different from those generally applicable to stockholders and reports and documents filed with the SEC, and in some cases were qualified by disclosures set forth in schedules that were confidentially provided by Anadigics to us and II-VI but are not publicly filed as part of the Merger Agreement. Moreover, information concerning the subject matter of the representations and warranties, which do not purport to be accurate as of the date of this Offer to Purchase, may have changed since the date of the Merger Agreement and subsequent developments or new information qualifying a representation or warranty may have been included in this Offer to Purchase.

The Merger Agreement provides that we will commence the Offer as promptly as practicable but in no event more than twelve (12) business days after the date of the Merger Agreement, and that, subject to the satisfaction of the Minimum Condition and the satisfaction or waiver by us of the other conditions that are described in Section 15 — “Conditions to the Offer,” II-VI will cause us to accept for payment, and we will accept for payment, all Shares validly tendered and not validly withdrawn pursuant to the Offer promptly after the Expiration Date. The initial Expiration Date shall be 11:59 P.M., New York City time, on the date that is twenty (20) business days (calculated in accordance with Rule 14d-1(g)(3) of the Exchange Act) after the date on which the Offer is first commenced.

Our obligations to accept for payment, and pay for, any Shares tendered pursuant to the Offer are subject to the conditions set forth in Section 15 — “Conditions to the Offer” (the “Offer Conditions”). The Offer Conditions are for the sole benefit of II-VI and us, and we expressly reserve the right to (i) increase the Offer Price, (ii) waive any condition to the Offer from time to time other than the Minimum Condition, and (iii) make any other changes in the terms and conditions of the Offer not inconsistent with the terms of the Merger Agreement; provided, however, we or II-VI cannot (A) decrease the Offer Price, (B) change the form of consideration payable in the Offer, (C) decrease the maximum number of Shares subject to the Offer, (D) impose conditions to the Offer in addition to the Offer Conditions, (E) amend or modify any of the Offer Conditions in any manner than adversely affects Anadigics stockholders, (F) amend or modify the Minimum Condition, or (G) extend or otherwise change the Expiration Date in a manner other than as request or permitted by the Merger Agreement, in each case without the prior written consent of Anadigics (which Anadigics may grant or withhold in its sole discretion).

The Merger Agreement provides that we will extend the Offer (a) for successive extension periods of not more than ten (10) business days each, or such period as II-VI and Anadigics may agree, in order to permit the satisfaction of all remaining Offer Conditions (subject to our right to waive any condition to the Offer (other than the Minimum Condition) in accordance with the Merger Agreement), if at any scheduled Expiration Date any condition to the Offer has not been satisfied or waived (other than the Minimum Condition, which we may not waive), and (b) for the minimum period required by applicable law or any interpretation or position of the SEC or its staff or NASDAQ or its staff, provided that we are not obligated to extend the Offer beyond the End Date. We may also elect to provide a subsequent offering period (and one or more extensions thereof) pursuant to Rule 14d-11 of the Exchange Act of neither less than three business days nor more than twenty (20) business days following the Expiration Date, during which time Anadigics’s stockholders whose Shares have not been tendered prior to the Expiration Date (or whose Shares were tendered and later withdrawn prior to the Expiration Date) may tender, but not withdraw, their Shares and receive the Offer Price.

The Anadigics Board has, at a meeting duly called and held, unanimously (i) determined that the Merger Agreement and the transactions contemplated by the Merger Agreement are advisable, fair to and in the best interests of Anadigics and its stockholders, (ii) approved and declared advisable the Merger Agreement, and the transactions contemplated by the Merger Agreement in accordance with the requirements of the DGCL, (iii) resolved to recommend that Anadigics’s stockholders accept the Offer and tender their Shares to us pursuant to the Offer (such recommendation, the “Anadigics Board Recommendation”), and (iv) adopted a resolution having the effect of causing the anti-takeover provisions contained in Section 203 of the DGCL applicable to a “business combination” (as defined in Section 203 of the DGCL) not apply to the transactions contemplated by the Merger Agreement.

The Merger Agreement provides that, as soon as practicable following the consummation of the Offer (and in any event not later than the second business day after the satisfaction or waiver of the last Offer Condition to be satisfied or waived), subject to the terms and conditions of the Merger Agreement, and in accordance with the DGCL, at the Effective Time:

Certificate of Incorporation; Bylaws; Directors and Officers of the Surviving Corporation. At the Effective Time, (i) the certificate of incorporation of the Surviving Corporation will be amended and restated in its entirety to be as set forth in Exhibit B to the Merger Agreement (which is substantially similar to our certificate of incorporation), (ii) the bylaws of the Surviving Corporation will be amended and restated to be as set forth on Exhibit C to the Merger Agreement (which are substantially similar to our bylaws) and (iii) the directors and officers of the Surviving Corporation immediately after the Effective Time will be the respective individuals who are designated as our directors and officers immediately prior to the Effective Time.

Merger Closing Conditions. Our obligations and the obligations of II-VI, on the one hand, and Anadigics, on the other hand, to effect the Merger are each subject to the satisfaction of each of the following conditions (which are in addition to the Offer Conditions described below in Section 15 — “Conditions to the Offer”):

Merger Consideration. At the Effective Time, each Share then outstanding (other than Shares that are held by any stockholders who properly demand appraisal in connection with the Merger as described in Section 16 — “Certain Legal Matters — Appraisal Rights”) (each an “Eligible Share”) will be converted into the right to receive the Offer Price, without interest, less any applicable withholding taxes, except for Shares then owned by II-VI, Purchaser, Anadigics or any of their respective wholly owned subsidiaries, which Shares will be cancelled without any consideration delivered in exchange therefor.

Payment for Shares. Prior to the Acceptance Time, II-VI will designate Computershare Trust Company, N.A. as paying agent to make payment of the consideration payable in the Merger (in such capacity, the “Paying Agent”). At the Closing, II-VI will deposit, or cause to be deposited, with the Paying Agent sufficient funds to pay the aggregate merger consideration payable in respect of the Shares.

Promptly after the Effective Time, the Paying Agent will mail to each holder of Shares (other than Shares then owned by II-VI, Anadigics or any of their respective wholly-owned subsidiaries) a Letter of Transmittal and instructions advising the stockholders how to surrender Eligible Shares represented by Share Certificates or book

entry (“Book-Entry Shares”) in exchange for the consideration payable in the Merger. The Paying Agent will pay the consideration payable in the Merger to the holders of Eligible Shares upon (1) surrender of a Share Certificate for shares held in certificate form, together with a Letter of Transmittal, duly completed and validly executed in accordance with the instructions therein or (2) receipt by the Paying Agent of an Agent’s Message in respect of such Book-Entry Shares (or such other evidence, if any, of transfer as the Paying Agent may reasonably request). Interest will not be paid or accrue in respect of the consideration payable in the Merger.

If any cash deposited with the Paying Agent is not claimed within 180 days following the Effective Time, such cash will be returned to the Surviving Corporation, upon its demand, and any stockholders who have not theretofore complied with the Share exchange procedures in the Merger Agreement will thereafter look only to the Surviving Corporation for payment of their claims for the consideration payable in the Merger, without interest, less any applicable withholding taxes. Notwithstanding the foregoing, neither the Surviving Corporation nor the Paying Agent will be liable to any holder of Shares for any consideration payable in the Merger delivered in respect of such Shares to a public official pursuant to abandoned property, escheat or other similar applicable law.

The transmittal instructions will include instructions regarding actions to be taken if the stockholder has lost a Share Certificate or if it has been stolen or destroyed. In order to obtain the consideration payable in respect of the Shares evidenced by such lost, stolen or destroyed Share Certificate, the stockholder will have to provide an affidavit to that fact (which will include an agreement to indemnify II-VI, the Surviving Corporation and the Paying Agent against all expenses, losses and claims that may be incurred in respect of such lost, stolen or destroyed Share Certificate) and, if required by II-VI, post a bond in a customary amount and upon such terms as may be required by II-VI as indemnity against any claim that may be made against it in respect of such Share Certificate.

Anadigics Options. At the Effective Time, each Anadigics Option granted under any Anadigics Equity Plan (as defined below) other than Anadigics’s Employee Stock Purchase Plan, Amended and Restated (May 13, 2010) (the “ESPP”) that is outstanding immediately prior to the Effective Time and that is not then fully vested and exercisable will become fully vested and exercisable as of immediately prior to the Effective Time. At the Effective Time, each outstanding Anadigics Option (after giving effect to the acceleration described above) will be cancelled and, in consideration for such cancellation, the holders thereof will automatically receive, as soon as practicable but in no event more than thirty (30) days following the Effective Time, an amount in cash equal to (i) the total number of shares of subject to such Anadigics Option, multiplied by (ii) the excess, if any of (A) the Offer Price over (B) the per share exercise price for such Anadigics Option, without interest and subject to any applicable tax withholding.

Anadigics Restricted Stock Unit Awards. Each time-based restricted stock unit award for Shares and each performance-based restricted stock unit award for Shares granted and earned for 2013 performance and for the first tranche of 2015 performance, in each case granted under any Anadigics Equity Plan other than the ESPP (each, an “Anadigics Restricted Stock Unit Award”) that is outstanding immediately prior to the Effective Time and that is not then fully vested will become fully vested as of immediately prior to the Effective Time. At the Effective Time, all Anadigics Restricted Stock Unit Awards outstanding immediately prior to the Effective Time (after giving effect to the acceleration of vesting described above) will be cancelled and, in consideration for such cancellation, the holders thereof will automatically receive, as soon as practicable but in no event more than thirty (30) days following the Effective Time, an amount in cash equal to (i) the total number of Shares subject to such Anadigics Restricted Stock Unit Award, multiplied by (ii) the Offer Price, without interest and subject to any applicable tax withholding. Each performance-based restricted stock unit award for Shares under any Anadigics Equity Plan and that is not an Anadigics Restricted Stock Unit Award that is outstanding immediately prior to the Effective Time will be cancelled without consideration as of the Effective Time. All other unvested performance-based restricted stock unit awards will be cancelled without payment of any consideration.

“Anadigics Equity Plans” means, collectively, Anadigics’s 1995 Long-Term Incentive and Share Award Plan for Officer and Directors; Anadigics’s 1997 Long Term Incentive and Share Award Plan; Anadigics’s Amended and Restated 2005 Long Term Incentive and Share Award Plan; Anadigics’s 2015 Long Term Incentive and Share Award Plan and the ESPP, each as amended from time to time, including the programs and forms of agreement adopted thereunder.

The Merger Agreement contains representations and warranties of II-VI, us and Anadigics. Some of the representations and warranties in the Merger Agreement made by Anadigics are qualified as to “materiality” or “Material Adverse Effect.” For purposes of the Merger Agreement, a “Material Adverse Effect” means any change, event, condition, occurrence, fact, circumstance, effect, action or omission that, individually or in the aggregate, does or is reasonably expected to (i) result in a material adverse effect on the assets, liabilities, business, properties, financial condition, results of operations or prospects of Anadigics and its subsidiaries, taken as a whole, (ii) prevent, materially impede or materially delay the consummation by Anadigics of the Merger or the other transactions contemplated by the Merger Agreement or (iii) result in a material impairment of the ability of II-VI and its subsidiaries to continue operating the business of Anadigics and its subsidiaries after the closing of the Merger in substantially the same manner as it was operated immediately prior to the date of the Merger Agreement; provided, however, that a “Material Adverse Effect” does not include any changes, events, conditions, occurrences, facts, circumstances, effects, actions or omissions (whether individually or in the aggregate) resulting from, attributable or arising out of any of the following:

In the Merger Agreement, Anadigics has made customary representations and warranties to II-VI and us with respect to, among other things:

In the Merger Agreement, we and II-VI have made customary representations and warranties to Anadigics with respect to, among other things:

None of the representations and warranties contained in the Merger Agreement survive the consummation of the Merger.

The Merger Agreement provides that, except (i) as required or otherwise contemplated under the Merger Agreement, (ii) with the written consent of II-VI (not to be unreasonably withheld, conditioned or delayed), and (iii) as previously disclosed to II-VI in connection with entering into the Merger Agreement, during the period from the date of the Merger Agreement until the Offer Acceptance Time (or the termination of the Merger Agreement, if earlier), Anadigics and its subsidiaries will conduct their business and operations in the ordinary course and use commercially reasonable efforts to maintain compliance with applicable law and the requirements of their material contracts. Anadigics will also use reasonable efforts to preserve intact the components of its and its subsidiaries’ current business organization, including keeping available the services of its current officers, employees and consultants, and will use all reasonable efforts to maintain relations and goodwill with their respective suppliers, distributors, manufacturers, customers and other business associates and governmental bodies.

In addition, during the same period, except (i) as required or otherwise contemplated under the Merger Agreement, (ii) with the written consent of II-VI (not to be unreasonably withheld, conditioned or delayed), or (iii) as previously disclosed to II-VI in connection with entering into the Merger Agreement, Anadigics will not, and will not permit any of its subsidiaries to, take certain actions, including the following:

From and after the date of the Merger Agreement until the earlier of the Acceptance Time and the termination of the Merger Agreement (the “Pre-Closing Period”), neither Anadigics nor its subsidiaries nor either of their representative, directly or indirectly, will:

Notwithstanding the above, at any time prior to the Offer Acceptance Time, Anadigics is not prohibited from furnishing information regarding itself and its subsidiaries to, or participating in discussions or negotiations with, any person (and waiving such Person’s noncompliance with any confidentiality or “standstill” provision) in response to an unsolicited bona-fide written Acquisition Proposal that is submitted after the date of the Merger Agreement to Anadigics by such person (and not withdrawn) if (1) such Acquisition Proposal did not result from the breach of Anadigics’s non-solicitation obligations under the Merger Agreement, (2) the Anadigics Board concludes in good faith, after consultation with its outside legal counsel and its financial advisor of nationally recognized reputation, that such bona-fide written Acquisition Proposal constitutes or could reasonably be expected to lead to a Superior Offer (as defined below) and that the failure to take such action would be reasonably likely to result in a breach of the fiduciary duties of the Anadigics Board to Anadigics’s stockholders under applicable law, (3) prior to furnishing such information, Anadigics receives from such third party an executed confidentiality agreement in customary form that is no less favorable to Anadigics than the confidentiality agreement entered into by Anadigics and II-VI, and (4) Anadigics concurrently notifies II-VI that it is taking such action and, if it is furnishing information to such Person, furnishes all such information to II-VI (to the extent not previously furnished or made available to II-VI or its representatives).

For purposes of the Merger Agreement, “Acquisition Proposal” means any inquiry, offer or proposal (other than an inquiry, offer or proposal made or submitted by II-VI) relating to or that could reasonably be expected to lead to any Acquisition Transaction, which is defined as any transaction or series of transactions (other than the transactions contemplated by the Merger Agreement), involving (1) any merger, consolidation, business combination (including by way of share exchange, joint venture or any similar transaction) or similar transaction involving Anadigics pursuant to which any Person or group (other than Anadigics stockholders immediately prior to consummation of the transaction) would hold 15% or more of the outstanding shares of Anadigics common stock after consummation of such transaction, or as a result of which Anadigics stockholders immediately prior to the consummation of such transaction would hold less than 85% of the outstanding shares of Anadigics common stock after consummation of such transaction, (2) any direct or indirect sale, license, lease, transfer, exchange or other disposition of any business or tangible or intangible assets representing 15% or more of the consolidated assets of Anadigics and its subsidiaries (or assets accounting for 15% or more of Anadigics’s income or revenue), taken as a whole, (3) any direct or indirect issuance, sale or other disposition, of securities (or options, rights or warrants to purchase, or securities convertible into or exchangeable for, such securities) representing 15% or more of the outstanding shares of capital stock or voting power of Anadigics or any of its subsidiaries, (4) any tender offer or exchange offer that if consummated would result in or would reasonably be expected to result in any person or group beneficially owning 15% or more of the outstanding shares of common stock or voting power of Anadigics, or in which any person or group will acquire the right to acquire beneficial ownership of 15% or more of the outstanding shares of common stock or voting power of Anadigics, or (5) any combination of the foregoing.

For purposes of the Merger Agreement, “Superior Offer” means an unsolicited, bona-fide written Acquisition Proposal (substituting each reference above in the definition of “Acquisition Proposal” to 15% with 80%) made by a third party after the date of the Merger Agreement and not resulting from a breach of Anadigics’s non-solicitation obligations described above, and which the Anadigics Board determines, in good faith, after consultation with its outside legal counsel and its financial advisor of nationally recognized

reputation, to be more favorable to Anadigics’s stockholders from a financial point of view than the terms of the Offer and the Merger and that is reasonably capable of being completed on the terms proposed, taking into account all relevant factors, and for which financing, if a cash transaction, is not a condition to the consummation of the purchase transaction and is reasonably determined to be available by the Anadigics Board.

During the period from the date of the Merger Agreement until the earlier of the Acceptance Time and the termination of the Merger Agreement, Anadigics must promptly (and in no event later than 24 hours after receipt thereof) advise II-VI orally and in writing of any Acquisition Proposal, any inquiry, indication of interest, proposal, offer or request that could reasonably be expected to lead to an Acquisition Proposal, including (a) the identity of the person making or submitting such Acquisition Proposal, inquiry, indication of interest, proposal, offer or request, (b) the material terms and conditions of such Acquisition Proposal, inquiry, indication of interest, proposal, offer or request, and (c) an unredacted copy of all written materials provided in connection therewith. Anadigics must keep II-VI promptly informed of any material change in the status, terms and pertinent details of any such Acquisition Proposal, inquiry, indication of interest, proposal, offer or request, including by providing (within 24 hours of receipt) an unredacted copy of all written materials subsequently provided in connection with such Acquisition Proposal, inquiry, indication of interest, proposal, offer or request.

Immediately following the execution of the Merger Agreement, except as otherwise permitted by the Merger Agreement, Anadigics must immediately cease and cause to be terminated any existing discussions with any person that relate to any Acquisition Proposal or any inquiry, indication of interest, proposal, offer or request that could reasonably be expected to lead to an Acquisition Proposal, and will terminate such person’s access to any physical or electronic data rooms in connection with such Acquisition Proposal. Immediately following the execution of the Merger Agreement, except as permitted by the Merger Agreement, Anadigics must promptly (but in no event later than one (1) business day following the date of the Merger Agreement) demand that each person (other than Purchaser or II-VI) that has executed a confidentiality agreement with Anadigics or any of its affiliates or any of its or their representatives with respect to such person’s consideration of a possible Acquisition Proposal to immediately return or destroy all confidential information furnished by Anadigics, any of its subsidiaries or any of its or their affiliates or representatives to such person, such person’s subsidiaries or any of their respective affiliates or representatives.

The Anadigics Board has made the Anadigics Board Recommendation that the holders of the Shares accept the Offer and tender their Shares into the Offer. The Anadigics Board has also agreed to include the Anadigics Board Recommendation in the Schedule 14D-9 and consented to the inclusion of the Anadigics Board Recommendation in this Offer to Purchase and documents related to the Offer.

In addition, except as expressly permitted by the non-solicitation provisions of the Merger Agreement, neither Anadigics, the Anadigics Board nor any committee thereof may (i) withhold, fail to include in (or remove from) the Schedule 14D-9, withdraw, qualify or modify the Anadigics Board Recommendation in any manner adverse to II-VI or us, (ii) approve, recommend, submit to stockholders for approval and adoption or declare advisable any Acquisition Proposal, (iii) fail to publicly reaffirm the Anadigics Board Recommendation within five (5) business days after receipt of a written request by II-VI to provide such reaffirmation following the commencement by a third party of a tender offer or exchange offer related to the Shares or public disclosure of an Acquisition Proposal other than a commenced tender offer or commenced exchange offer, or (iv) within five (5) business days following the commencement by a third party of any tender offer or exchange offer related to the Shares, fail to file a Schedule 14D-9 disclosing that Anadigics recommends rejection of such tender offer or exchange offer (any such action, an “Adverse Change Recommendation”)

However, at any time prior to the Acceptance Time, the Anadigics Board may make an Adverse Change Recommendation or terminate the Merger Agreement to enter into a binding written definitive acquisition agreement providing for the consummation of a transaction constituting a Superior Offer (a “Specified Agreement”) if and only if (in the event of a Superior Offer):

The requirements described above also apply to any material amendment to any Acquisition Proposal or any successive Acquisition Proposals, in which case references to three (3) business days will instead be two (2) business days.

In addition, under certain circumstances, the Anadigics Board may make an Adverse Change Recommendation with respect to an “Intervening Event,” which is defined as any material development or event, or material change in circumstances that occurs or arises after the date of the Merger Agreement and that (i) was not known or reasonably foreseeable by the Anadigics Board as of the date of the Merger Agreement, (ii) occurs or arises after the date of the Merger Agreement, (iii) did not result from the breach of any of Anadigics’s obligations under the Merger Agreement (including its non-solicitation obligations, described above), and (iv) is neither remote nor speculative. Neither the receipt, existence or terms of any Acquisition Proposal (or any matter relating to any Acquisition Proposal) may be considered an “Intervening Event”. The Anadigics Board may make an Adverse Change Recommendation with respect to an “Intervening Event” if and only if:

In the event of any material change to the facts and circumstances relating to an Intervening Event, such change would require Anadigics to deliver a new Change of Recommendation Notice to II-VI and to comply again with the procedures described above.

Nothing contained in the procedures described in the paragraph above will prohibit the Anadigics Board from taking and disclosing to the Anadigics stockholders a position contemplated by Rule 14e-2(a) under the Exchange Act, making a statement contemplated by Item 1012(a) of Regulation M-A or Rule 14d-9(f) promulgated under the Exchange Act, or otherwise making any disclosure to Anadigics’s stockholders if the Anadigics Board determines in good faith (after consulting with outside legal counsel) that the failure to make such disclosure would be reasonably likely to result in a breach of its fiduciary duties under applicable law; provided, however, that no such disclosure may not contain an Adverse Change Recommendation. Neither Anadigics nor the Anadigics Board is permitted to recommend that Anadigics’s stockholders tender any securities in connection with any tender or exchange offer or otherwise approve, endorse or recommend any Acquisition Proposal, unless in each case, in connection therewith, the Anadigics Board effects an Adverse Change Recommendation in accordance with the terms of the Merger Agreement.

The Merger will be governed by Section 251(h) of the DGCL. Accordingly, after the consummation of the Offer, II-VI, we and Anadigics have agreed to take all necessary and appropriate action to cause the Merger to become effective as soon as practicable without a meeting of stockholders of Anadigics in accordance with Section 251(h) of the DGCL.

ESPP. On December 31, 2015, the ESPP expired by its terms. Immediately prior to the Effective Time, Anadigics will take all actions necessary or required under applicable law to terminate the Anadigics’s 2016 Employee Stock Purchase Plan (the “2016 ESPP”). Since the termination of the ESPP, no offerings have been or will be made under the 2016 ESPP.

Other Matters. Anadigics has agreed to take all actions necessary or required under the applicable plan or other legal regulations to cause, as of immediately prior to the Effective Time, the termination of each Anadigics Equity Plan and Anadigics’s Severance Pay Plan. Furthermore, Anadigics has agreed to obtain written acknowledgement satisfactory to II-VI from each holder of Anadigics Options that have an exercise price greater than the Offer Price, indicating that such holder agrees that such award will be cancelled and extinguished as of the Effective Time without payment of any consideration.

Anadigics has agreed that, prior to the Acceptance Time, it will (acting through the Anadigics Board or its compensation committee) cause to be exempt under Rule 14d–10(d) of the Exchange Act any employment compensation, severance or other employee benefit arrangement entered into on or after the date of the Merger

Agreement by Anadigics, II-VI or any of their respective affiliates with current or future directors, officers or employees of Anadigics and its affiliates and to ensure that any such arrangements fall within the safe harbor provisions of such rule.

Each of II-VI, us and Anadigics have agreed to cooperate with one another and use reasonable best efforts to take all actions, and do all things reasonably necessary, proper or advisable on its part under the Merger Agreement and applicable law to consummate and make effective the transactions contemplated by the Merger Agreement as soon as reasonably practicable, including preparing and filing as promptly as reasonably practicable all documentation to effect all necessary notices, reports and other filings and to obtain as promptly as practicable all consents, registrations, approvals, permits and authorizations necessary or advisable to be obtained from any governmental body in order to consummate the transactions contemplated by the Merger Agreement.

Neither II-VI nor any of its affiliates is required to agree, consent or commit to any divestitures or licenses or other undertakings or to proffer to, or agree to, sell or license or hold separate and agree to sell, license transfer or assign, before or after the Effective Time, (i) propose, negotiate, commit to or effect, by consent decree, hold separate order or otherwise, before or after the Effective Time, the sale, divestiture, licensing or disposition of any assets or businesses of II-VI or its subsidiaries and affiliates, or of Anadigics or its subsidiaries, (ii) otherwise take or commit to take any action that would limit the freedom of action of II-VI, its subsidiaries or affiliates with respect to, or would limit II-VI’s or its affiliates’ ability to retain, any of the businesses, product lines or assets of II-VI or its subsidiaries, in each case as may be required to avoid the entry of, or to effect the dismissal or termination of, any injunction, temporary restraining order or other order in any legal proceeding, or (iii) defend any lawsuit or other legal proceeding, whether judicial or administrative, challenging the Merger Agreement or the consummation of the Offer, the Merger or any of the other transactions contemplated by the Merger Agreement (other than the defense against any request for preliminary relief).

We and II-VI, on the one hand, and Anadigics, on the other hand, have agreed to (i) give the other parties prompt notice of the making or commencement of any request, inquiry, investigation, action or legal proceeding by or before any governmental body with respect to the transactions contemplated by the Merger Agreement of which such party had knowledge, (ii) keep the other parties reasonably informed as to the status of any such request, inquiry, investigation, action or legal proceeding, and (iii) promptly inform the other parties of any communication to or from the United States Federal Trade Commission (“FTC”), the United States Department of Justice (“DOJ”) or any other governmental body to the extent regarding the transactions contemplated by the Merger Agreement, or regarding any such request, inquiry, investigation, action or legal proceeding, and provide a copy of all written communications.

Each of Anadigics and II-VI have the right to review in advance, and to the extent practicable each will consult the other on (and consider in good faith all comments reasonably proposed by the other party with respect to) all material information relating to such party and any of its subsidiaries that appears in any filing made with, or written materials submitted to, any governmental body in connection with the Offer and the transactions contemplated by the Merger Agreement. Anadigics and II-VI have further agreed to, as circumstances reasonably permit, consult with the other party in advance of any meeting or conference with a governmental body relating to the transactions contemplated by the Merger Agreement and give the other party the opportunity to attend and participate in such meetings and conferences.

Anadigics has agreed that if any state takeover law or similar law may become, or may purport to be, applicable to the transactions contemplated by the Merger Agreement, Anadigics and the Anadigics Board will grant such approvals and take such reasonable actions as are necessary so that the transactions contemplated by the Merger Agreement may be consummated as promptly as practicable on the terms and conditions

contemplated by the Merger Agreement and otherwise act to eliminate the effect of any such takeover law or similar law on any of the transactions contemplated by the Merger Agreement.

II-VI has agreed that, it or the Surviving Corporation will, and will cause the Surviving Corporation to, from the Effective Time until the sixth anniversary of the Effective Time:

II-VI agreed that substantially concurrently, but subsequent to, the execution of the Merger Agreement, it would, on behalf of Anadigics, pay the termination fee Aloha was required to pay in connection with terminating the Aloha Merger Agreement (the “Aloha Termination Fee”). II-VI paid the Aloha Termination Fee on January 15, 2016.

The Merger Agreement contains other customary covenants, including covenants relating to securityholder litigation, third party consents, public announcements and access, confidentiality, matters with respect to Section 16 of the Exchange Act, the resignation of Anadigics and its subsidiaries’ directors, notification of certain changes and developments (including changes that would result in any Offer Conditions not being capable of satisfaction prior to the End Date), stock exchange delisting and deregistration and payoff of Anadigics’s indebtedness.

Effect of Termination. If the Merger Agreement is terminated in accordance with its terms, the Merger Agreement will be of no further force or effect, subject to certain designated provisions of the Merger Agreement that survive, including the effect of termination, expenses and termination fee and other miscellaneous provisions and the confidentiality agreement between II-VI and Anadigics, which will remain in full force and effect in accordance with its terms. The termination of the Merger Agreement does not relieve any party from any liability for any willful and intentional breach of the Merger Agreement prior to the date of the termination.

Termination Fees. Anadigics has agreed to pay II-VI a termination fee of $1.2 million (the “Termination Fee”), if:

A “Specified Acquisition Transaction” is defined as an Acquisition Transaction (described above in “No Solicitation”) except that all references to 15% or to 85% are deemed references to 50%.

Anadigics has also agreed to repay to II-VI the Aloha Termination Fee in the event the Merger Agreement is terminated for any reason except a breach by us or a failure to obtain any regulatory approval necessary to consummate the transactions contemplated by the Merger Agreement, concurrently with any such termination.

Any Termination Fee and repayment of the Aloha Termination Fee will be paid as follows: (A) in the case of clause (i) above, substantially concurrently with the consummation of a Specified Acquisition Transaction, (B) in the case of clause (ii) above, within two (2) business days following termination of the Merger Agreement, or (C) in the case of clause (iii) above, concurrently with the termination of the Merger Agreement.

We, II-VI and Anadigics are entitled to seek an injunction or injunctions to prevent breaches of the Merger Agreement and to enforce specifically the terms and provisions thereof in addition to any other remedy to which they are entitled under the terms of the Merger Agreement, at law or in equity.

Except as provided in this Section 11 — “The Merger Agreement; Other Agreements — The Merger Agreement — Termination Fees,” all fees and expenses incurred in connection with the Merger Agreement and the transactions contemplated by the Merger Agreement will be paid by the party incurring such fees and expenses.

II-VI and Anadigics entered into a Mutual Non-Disclosure Agreement, dated as of November 16, 2015 (the “Non-Disclosure Agreement”). Under the terms of the Non-Disclosure Agreement, the parties agreed that, subject to certain exceptions, any confidential information regarding either party or any of their respective subsidiaries, affiliates or divisions furnished to the other party or its representatives would be kept confidential for a period of two (2) years, and such confidential information should be used by such parties and their respective representatives solely for the purpose of evaluating a possible transaction between II-VI and Anadigics. Effective December 11, 2015, Anadigics and II-VI entered into an amendment to the Non-Disclosure Agreement regarding certain procedures relating to selected customer and product information.

The foregoing summary of the Non-Disclosure Agreement does not purport to be complete and is subject to, and qualified in its entirety by, reference to the full text of the Non-Disclosure Agreement, a copy of which is filed as Exhibit (d)(3) to the Schedule TO, which is incorporated herein by reference.

Purpose of the Offer. We are making the Offer pursuant to the Merger Agreement in order to acquire control of, and ultimately following the Merger, the entire equity interest in, Anadigics. The purpose of the Merger is to acquire all outstanding Shares not tendered and purchased pursuant to the Offer. If the Offer is successful, subject to the satisfaction or waiver of the conditions to the obligations of II-VI and Purchaser to effect the Merger contained in the Merger Agreement, Purchaser intends to consummate the Merger as soon as practicable following the Acceptance Time.

Holders of Shares who tender their Shares in the Offer will cease to have any equity interest in Anadigics and will no longer participate in the future growth of Anadigics. If the Merger is consummated, the current holders of Shares will no longer have an equity interest in Anadigics and instead will only have the right to receive an amount in cash equal to the Offer Price or, to the extent that holders of Shares are entitled to and have properly demanded appraisal in connection with the Merger, the amounts to which such holders of Shares are entitled in accordance with Delaware law. Similarly, after selling your Shares in the Offer or the subsequent Merger, you will not bear the risk of any decrease in value of Anadigics.

Merger Without a Vote. If the Offer is consummated, we do not anticipate seeking the approval of Anadigics’s remaining public stockholders before effecting the Merger. Section 251(h) of the DGCL provides that following consummation of a successful tender offer for a public corporation, and subject to certain statutory provisions, if the acquiring corporation owns at least the amount of shares of each class of stock of the target corporation that would otherwise be required to adopt a merger agreement for the target corporation, and the other stockholders receive the same consideration for their stock in the merger as was payable in the tender offer, the acquiring corporation can effect a merger without the action of the other stockholders of the target corporation. Accordingly, if we consummate the Offer, we intend to effect the closing of the Merger without a vote of the stockholders of Anadigics in accordance with Section 251(h) of the DGCL.

Plans for Anadigics. The Merger Agreement provides that, following the consummation of the Offer and subject to the conditions set forth in the Merger Agreement, we will be merged with and into Anadigics, with Anadigics becoming the Surviving Corporation and a wholly-owned subsidiary of II-VI and all of the existing shares of Anadigics stock being cancelled and the 1,000 outstanding shares of our common stock becoming the only outstanding capital stock of the Surviving Corporation. Following the Merger at the Effective Time and until thereafter amended, the Anadigics certificate of incorporation will be replaced by our certificate of incorporation, the Anadigics bylaws will be replaced by our bylaws, the Anadigics directors will be replaced by our directors, the Anadigics officers will be replaced by our officers, and Anadigics will be controlled by II-VI. See Section 11 — “The Merger Agreement; Other Agreements — The Merger Agreement — Certificate of Incorporation; Bylaws; Directors and Officers of the Surviving Corporation.”

We are conducting a detailed review of Anadigics and its assets, operations, properties, products, corporate structure, capitalization, policies, management, and personnel, and we will continue to evaluate the business and operations of Anadigics during the pendency of the Offer. After consummation of the Offer and the Merger, II-VI will consider the changes it believes would be desirable in light of the circumstances that exist upon completion the Merger, and will take whatever actions it deems appropriate to integrate some or all of the assets, business, operations, and personnel of Anadigics into II-VI in the manner it concludes will best improve the business of II-VI and maximize its strategic plans for the acquisition, which plans may change over time and as circumstances change.

Except as described above and elsewhere in this Offer to Purchase, which reflect certain significant anticipated changes to Anadigics upon completion of the Merger, neither Purchaser nor II-VI has any other present plans or proposals that would relate to or result in (i) any extraordinary transaction involving Anadigics or any of its subsidiaries (such as a merger, reorganization or liquidation), (ii) any purchase, sale or transfer of a material amount of assets of Anadigics or any of its subsidiaries, (iii) any change in the Anadigics Board or management of Anadigics, (iv) any material change in Anadigics’s capitalization or dividend rate or policy or

indebtedness, (v) any other material change in Anadigics’s corporate structure or business, (vi) any class of equity securities of Anadigics being delisted from a national securities exchange or ceasing to be authorized to be quoted in an automated quotation system operated by a national securities association or (vii) any class of equity securities of Anadigics becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Exchange Act.

Because the Merger will be governed by Section 251(h) of the DGCL, no stockholder vote will be required to consummate the Merger. Following the consummation of the Offer and subject to the satisfaction of the remaining conditions set forth in the Merger Agreement, we, II-VI and Anadigics will consummate the Merger as soon as practicable. We do not expect there to be a significant period of time between the consummation of the Offer and the consummation of the Merger.

Market for Shares. The purchase of Shares pursuant to the Offer will reduce the number of holders of Shares and the number of Shares that might otherwise trade publicly, which could adversely affect the liquidity and market value of the remaining Shares held by stockholders other than II-VI and its affiliates. Neither II-VI nor its affiliates can predict whether the reduction in the number of Shares that might otherwise trade publicly would have an adverse or beneficial effect on the market price for, or marketability of, Shares or whether such reduction would cause future market prices to be greater or less than the Offer Price.

Stock Listing. Depending upon the number of Shares purchased pursuant to the Offer, the Shares may no longer meet the requirements for continued listing on NASDAQ. According to NASDAQ’s published guidelines, NASDAQ would consider delisting the Shares if, among other things, the total number of holders of Shares falls below 400 or the number of publicly held Shares falls below 750,000. Shares held by officers or directors of Anadigics or their immediate families, or by any beneficial owner of 10% or more of such Shares, ordinarily will not be considered as being “publicly held” for this purpose. According to Anadigics, as of January 14, 2016, 89,735,630 Shares were issued and outstanding. If, as a result of the purchase of Shares pursuant to the Offer or otherwise, the Shares no longer meet the requirements of NASDAQ for continued listing and such listing is discontinued, the market for Shares could be adversely affected.

In addition, on June 18, 2015, Anadigics announced that it had received a NASDAQ delisting notice, which provided notification that Anadigics’s share price was not in compliance with the minimum bid price requirement of $1.00 per share for continued listing on the NASDAQ Global Select Market under the applicable NASDAQ listing rule. Anadigics was provided an initial period of 180 calendar days, or until December 15, 2015, to regain compliance with the minimum bid price requirement. Anadigics applied to transfer the Shares from the NASDAQ Global Select Market to the NASDAQ Capital Market and in December 2015, Anadigics was notified by NASDAQ that the application was approved. As of December 17, 2015, the Shares were transferred to the NASDAQ Capital Market. The Shares will continue to trade on the NASDAQ Capital Market until June 13, 2016 pending the listing for the Shares regaining compliance with applicable NASDAQ listing rules.

If NASDAQ were to delist the Shares, it is possible that Shares would continue to trade on another securities exchange or in the over-the-counter market and that price or other quotations would be reported by such exchange or other sources. The extent of the public market for Shares and the availability of such quotations would depend, however, upon such factors as the number of stockholders and/or the aggregate market value of the publicly traded Shares remaining at such time, the interest in maintaining a market in Shares on the part of securities firms, the possible termination of registration under the Exchange Act (as described below), and other factors. We cannot predict whether the reduction in the number of Shares that might otherwise trade publicly would have an adverse or beneficial effect on the market price or marketability of Shares or whether it would cause future market prices to be greater or less than the Offer Price. Trading in Shares will cease upon the Effective Time if trading has not ceased earlier as discussed above.

After the consummation of the Offer, II-VI may cause Anadigics to take all action necessary to be treated as a “controlled company,” as defined by Rule 5615(c) of the NASDAQ Rules (or any successor provision), which means that Anadigics would be exempt from the requirement that the Anadigics Board be composed of a majority of “independent directors” and the related rules covering the independence of directors serving on the nominating and corporate governance committee and the compensation committee of the Anadigics Board. The controlled company exemption does not modify the independence requirements for Anadigics’s audit committee or the requirements of the Merger Agreement relating to independent directors and the independent director committee. See Section 11 — “The Merger Agreement; Other Agreements — The Merger Agreement — Anadigics’s Board of Directors.”

Exchange Act Registration. The Shares are currently registered under the Exchange Act. Following the purchase of Shares in the Offer and subject to the satisfaction or waiver of the remaining conditions set forth in the Merger Agreement, we, II-VI and Anadigics will consummate the Merger as soon as practicable, following which the Shares will no longer be publicly owned. Following the consummation of the Merger, we intend to take steps to cause the termination of the registration of Shares under the Exchange Act as promptly as practicable and may in the future take steps to cause the suspension of all of Anadigics’s reporting obligations under the Exchange Act. Pursuant to the rules of the SEC and the views expressed by the SEC staff, Anadigics may terminate its Exchange Act registration and suspend its reporting obligations if (i) the outstanding Shares are not listed on a national securities exchange, (ii) there are fewer than 300 holders of record of Shares and (iii) Anadigics is not otherwise required to furnish or file reports under the Exchange Act. Such termination and suspension, once effective, would reduce the information that Anadigics must furnish to its stockholders and to the SEC. The deregistration of the Shares, once effective, would make certain provisions of the Exchange Act, including the short-swing profit recovery provisions of Section 16(b) of the Exchange Act and the requirement of furnishing a proxy statement or information statement in connection with stockholders’ meetings or actions in lieu of a stockholders’ meeting pursuant to Section 14(a) or 14(c) of the Exchange Act and the related requirement to furnish an annual report to stockholders, no longer applicable with respect to the Shares. In addition, if the Shares are no longer registered under the Exchange Act, the requirements of Rule 13e-3 under the Exchange Act with respect to “going private” transactions would no longer be applicable to Anadigics. Furthermore, the ability of Anadigics’s affiliates and persons holding restricted securities to dispose of such securities pursuant to Rule 144 or Rule 144A under the Securities Act of 1933, as amended, could be impaired or eliminated. If registration of the Shares under the Exchange Act were terminated, the Shares would no longer be eligible for NASDAQ reporting or for continued inclusion on the list of the Board of Governors of the Federal Reserve System (the “Federal Reserve Board”) for margin securities.

Margin Regulations. The Shares are currently “margin securities” under the regulations of the Federal Reserve Board, which has the effect, among other things, of allowing brokers to extend credit using the Shares as collateral. Depending upon factors similar to those described above regarding listing and market quotations, it is possible that, following the Offer, the Shares may no longer constitute “margin securities” for the purposes of the margin regulations of the Federal Reserve Board, in which event the Shares would be ineligible as collateral for margin loans made by brokers.

As discussed in Section 11 — “The Merger Agreement; Other Agreements — The Merger Agreement — Conduct of Business of Anadigics,” the Merger Agreement provides that, from the date of the Merger Agreement to the Acceptance Time, without the prior written consent of II-VI or otherwise permitted by the Merger Agreement, Anadigics will not, and will not permit any of its subsidiaries to declare, authorize, set aside or pay any dividend or make any other distribution in respect of any shares of its capital stock, or purchase or repurchase, redeem or otherwise acquire any shares of its capital stock, other than (i) dividends or distributions between or among Anadigics and its subsidiaries; (ii) acquisitions by Anadigics of its capital stock in connection with the surrender by holders of Anadigics Options in order to pay the exercise price of such Anadigics Options; (iii) the withholding of shares of its capital stock to satisfy tax obligations with respect to awards granted

pursuant to Anadigics Equity Plans; and (iv) the acquisition by Anadigics of Anadigics Options and Anadigics Restricted Stock Unit Awards or purchase rights under the ESPP in accordance with the terms thereof in effect as of the date of the Merger Agreement, as applicable, in connection with the forfeiture of such awards. Neither we nor II-VI anticipate waiving this restriction or otherwise consenting to the payment of any dividend on Anadigics’s capital stock. Accordingly, it is anticipated that no dividends will be declared or paid on the Shares following the date of the Merger Agreement.

Notwithstanding any other provisions of the Offer or the Merger Agreement, we will not be obligated to accept for payment, and subject to the rules and regulations of the SEC, including Rule 14e-1(c) under the Exchange Act (relating to our obligation to pay for or return tendered Shares promptly after termination or withdrawal of the Offer), will not be obligated to pay for, and may delay acceptance or payment for, any validly tendered Shares pursuant to the Offer if:

Except as described in this Section 16, we are not aware of any material pending legal proceeding relating to the Offer. Except as described in this Section 16, based on our and II-VI’s review of publicly available filings by Anadigics with the SEC and other information regarding Anadigics, we are not aware of any governmental license or regulatory permit that appears to be material to Anadigics’s business that might be adversely affected by our acquisition of Shares as contemplated in this Offer to Purchase or of any approval or other action by any governmental, administrative or regulatory authority or agency, domestic or foreign, that would be required for the acquisition or ownership of Shares by us as contemplated in this Offer to Purchase. However, there can be no assurance that any such approval or other action, if needed, would be obtained or would be obtained without substantial conditions or that if such approvals were not obtained or such other actions were not taken, adverse consequences might not result to Anadigics’s business, or certain parts of Anadigics’s business might not have to be disposed of, any of which could cause us to elect to terminate the Offer without the purchase of Shares thereunder under certain conditions. See Section 15 — “Conditions to the Offer.”

Except for the following, as of the date of this Offer, we are not aware of any material pending legal proceeding relating to the Offer or the Merger.

Purchaser and II-VI are aware of a class action complaint captioned Wes Zalewski v. Anadigics, Inc., et al., filed in the Superior Court of New Jersey, Somerset County (the “Zalewski Litigation”). In the Zalewski Litigation, the plaintiff, a stockholder in Anadigics, generally alleges, among other things, that the members of Anadigics’s board of directors breached their fiduciary duties by failing to take steps to maximize the value to be paid to Anadigics’s shareholders, putting the board of directors’ personal interests ahead of the interests of Anadigics, using allegedly unfair deal protection devices, and having an unfair and inadequate process in negotiating the Offer and Merger. The plaintiff also has named the Purchaser and II-VI as defendants in the complaint, alleging that both Purchaser and II-VI aided and abetted the breaches of fiduciary duty by the Anadigics board of directors. The plaintiff in the Zalewski Litigation generally seeks, among other relief, declaratory and injunctive relief prohibiting consummation of the proposed Offer and Merger, rescission of the proposed Offer and Merger if consummated prior to final judgment, attorneys’ fees and expenses, and other forms of relief. Purchaser and II-VI are reviewing the allegations in the Zalewski Litigation, but believe the Zalewski Litigation is without merit and intend to vigorously defend against the allegations.

A number of states (including Delaware, where Anadigics is incorporated) have adopted takeover laws and regulations that purport, to varying degrees, to be applicable to attempts to acquire securities of corporations that are incorporated in such states or that have substantial assets, stockholders, principal executive offices or principal places of business therein. To the extent that certain provisions of certain of these state takeover statutes purport to apply to the Offer or the Merger, we believe there are reasonable bases for contesting such laws. In Edgar v. MITE Corp., the Supreme Court of the United States invalidated on constitutional grounds the Illinois

Business Takeover Statute that, as a matter of state securities law, made takeovers of corporations meeting certain requirements more difficult. However, in 1987, in CTS Corp. v. Dynamics Corp. of America, the Supreme Court held that the State of Indiana could, as a matter of corporate law, constitutionally disqualify a potential acquiror from voting shares of a target corporation without the prior approval of the remaining stockholders where, among other things, the corporation is incorporated in, and has a substantial number of stockholders in, the state. Subsequently, in TLX Acquisition Corp. v. Telex Corp., a Federal District Court in Oklahoma ruled that the Oklahoma statutes were unconstitutional insofar as they apply to corporations incorporated outside Oklahoma in that they would subject such corporations to inconsistent regulations. Similarly, in Tyson Foods, Inc. v. McReynolds, a Federal District Court in Tennessee ruled that four Tennessee takeover statutes were unconstitutional as applied to corporations incorporated outside Tennessee. This decision was affirmed by the United States Court of Appeals for the Sixth Circuit.

Section 203 of the DGCL restricts an “interested stockholder” (including a person who owns or has the right to acquire 15% or more of the corporation’s outstanding voting stock) from engaging in a “business combination” (defined to include mergers and certain other actions) with certain Delaware corporations for a period of three years following the time such person became an interested stockholder. These restrictions will not be applicable to us and II-VI because the Anadigics Board has unanimously approved the Offer, the Merger, the Merger Agreement and the other transactions contemplated thereby, including for purposes of Section 203.

We are not aware of any other state takeover laws or regulations that are applicable to the Offer or the Merger and have not attempted to comply with any state takeover laws or regulations. If any government official or third party should seek to apply any such state takeover law to the Offer or the Merger or any of the other transactions contemplated by the Merger Agreement, we will use our reasonable best efforts to take, or cause to be taken, all action reasonably necessary so that the Offer, the Merger and the other transactions contemplated by the Merger Agreement may be consummated as promptly as practicable on the terms contemplated by the Merger Agreement and otherwise act to eliminate or minimize the effects of such statute or regulation on the Offer, the Merger or the other transactions contemplated by the Merger Agreement. In the event it is asserted that one or more state takeover statutes are applicable to the Offer or the Merger and an appropriate court does not determine that it is or they are inapplicable or invalid as applied to the Offer or the Merger, we might be required to file certain information with, or to receive approvals from, the relevant state authorities or holders of Shares, and we might be unable to accept for payment or pay for Shares tendered pursuant to the Offer, or might be delayed in continuing or consummating the Offer or the Merger. In such case, we might not be obligated to accept for payment or pay for any tendered Shares. See Section 15 — “Conditions to the Offer.”

The SEC has adopted Rule 13e-3 under the Exchange Act, which is applicable to certain “going private” transactions, and which may under certain circumstances be applicable to the Merger or other business combination following the purchase of Shares pursuant to the Offer in which we seek to acquire the remaining Shares not then held by us. We believe that Rule 13e-3 under the Exchange Act will not be applicable to the Merger because we were not, at the time the Merger Agreement was executed, and are not, an affiliate of Anadigics (for purposes of the Exchange Act); it is anticipated that the Merger will be effected within one year following the consummation of the Offer; and, in the Merger, stockholders will receive the same price per Share as the Offer Price.

Rule 13e-3 under the Exchange Act would otherwise require, among other things, that certain financial information concerning Anadigics and certain information relating to the fairness of the proposed transaction and the consideration offered to minority stockholders be filed with the SEC and disclosed to stockholders before the completion of a transaction.

No appraisal rights are available to the holders of Shares in connection with the Offer. However, if the Merger is consummated, the holders of Shares immediately prior to the Effective Time who (i) did not tender their Shares in the Offer; (ii) follow the procedures set forth in Section 262 of the DGCL and (iii) do not thereafter withdraw their demand for appraisal of such Shares or otherwise lose their appraisal rights, in each case in accordance with the DGCL, will be entitled to have their Shares appraised by the Delaware Court of Chancery and receive payment of the “fair value” of such Shares, exclusive of any element of value arising from the accomplishment or expectation of the Merger, together with a fair rate of interest, as determined by such court.

The “fair value” of any Shares could be based upon considerations other than, or in addition to, the price paid in the Offer and the market value of such Shares. Holders of Shares should recognize that the value so determined could be higher or lower than, or the same as, the Offer Price or the consideration payable in the Merger (which is equivalent in amount to the Offer Price). Moreover, we may argue in an appraisal proceeding that, for purposes of such proceeding, the fair value of such Shares is less than such amount.

Under Section 262 of the DGCL, where a merger is approved under Section 251(h), either a constituent corporation before the effective date of the merger, or the surviving corporation within ten 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 Section 262 of the DGCL. The Schedule 14d-9 constitutes the formal notice of appraisal rights under Section 262 of the DGCL.

As described more fully in the Schedule 14D-9, if a stockholder elects to exercise appraisal rights under Section 262 of the DGCL, such stockholder must do all of the following:

The foregoing summary of the appraisal rights of stockholders under the DGCL does not purport to be a complete statement of the procedures to be followed by stockholders desiring to exercise any appraisal rights available thereunder and is qualified in its entirety by reference to Section 262 of the DGCL. The proper exercise of appraisal rights requires strict and timely adherence to the applicable provisions of Delaware law. A copy of Section 262 of the DGCL is included as Annex A to the Schedule 14D-9.

The information provided above is for informational purposes only with respect to your alternatives if the Merger is consummated. If you tender your Shares into the Offer, you will not be entitled to exercise appraisal rights with respect to your Shares but, instead, subject to the conditions to the Offer, you will receive the Offer Price for your Shares.

Section 251(h) of the DGCL provides that stockholder approval of a merger is not required if certain requirements are met, including that (1) the acquiring company consummates a tender offer for any and all of the outstanding common stock of the company to be acquired that, absent Section 251(h) of the DGCL, would be entitled to vote on the merger, (2) following the consummation of such tender offer, the acquiring company owns at least such percentage of the stock of the company to be acquired that, absent Section 251(h) of the DGCL, would be required to adopt the merger, and (3) at the time that the board of directors of the company to be acquired approves the merger, no other party to the merger agreement is an interested stockholder under the DGCL. If the Minimum Condition is satisfied and we accept Shares for payment pursuant to the Offer, we will hold a sufficient number of Shares to ensure that Anadigics will not be required to submit the adoption of the Merger Agreement to a vote of the stockholders of Anadigics. Following the consummation of the Offer and subject to the satisfaction of the remaining conditions set forth in the Merger Agreement, we, II-VI and Anadigics will take all necessary and appropriate action to effect the Merger as promptly as practicable without a meeting of stockholders of Anadigics in accordance with Section 251(h) the DGCL.

We have retained the Depositary and the Information Agent in connection with the Offer. Each of the Depositary and the Information Agent will receive customary compensation, and the Depositary and the Information Agent will each receive, subject to certain limits, reimbursement for reasonable out-of-pocket expenses.

As part of the services included in such retention, the Information Agent may contact holders of Shares by personal interview, mail, electronic mail, telephone and other methods of electronic communication and may request brokers, dealers, commercial banks, trust companies and other nominees to forward the Offer materials to beneficial holders of Shares.

Except as set forth above, none of Purchaser or II-VI will pay any fees or commissions to any broker or dealer or other person for soliciting tenders of Shares pursuant to the Offer. Brokers, dealers, commercial banks, trust companies or other nominees will, upon request, be reimbursed by us for customary mailing and handling expenses incurred by them in forwarding the Offer materials to their customers.

The Offer is not being made to (nor will tenders be accepted from or on behalf of) holders of Shares in any state in which the making of the Offer or the acceptance thereof would be prohibited by administrative or judicial action pursuant to the laws of such state after a good faith effort by us to make the Offer comply with the laws of such state.

No person has been authorized to give any information or to make any representation on behalf of us not contained herein or in the Letter of Transmittal, and, if given or made, such information or representation must not be relied upon as having been authorized.

We and II-VI have filed with the SEC a Tender Offer Statement on Schedule TO pursuant to Rule 14d-3 under the Exchange Act, furnishing certain additional information with respect to the Offer, and may file amendments thereto. In addition, a Solicitation/Recommendation Statement on Schedule 14D-9 is being filed with the SEC by Anadigics pursuant to Rule 14d-9 under the Exchange Act, setting forth the recommendation of the Anadigics Board with respect to the Offer and the reasons for such recommendation and furnishing certain additional related information, and Anadigics may file amendments thereto. The Schedule TO and the Schedule 14D-9, including their respective exhibits, and any amendments to any of the foregoing, may be examined and copies may be obtained from the SEC’s Public Reference Room at 100 F Street, N.E., Washington, D.C. 20549,

or may be accessed electronically on the SEC’s website at www.sec.gov and are available from the Information Agent at the address and telephone number set forth on the back cover of this Offer to Purchase.

Each director and executive officer, as applicable, of Purchaser and II-VI is a citizen of the United States of America.

During the past five years, to the best of our knowledge, none of the persons listed below has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or been a party to any judicial or administrative proceeding (except for matters that were dismissed without sanction or settlement) that resulted in a judgment, decree or final order enjoining him, her or it from future violations of, or prohibiting activities subject to, U.S. federal or state securities laws, or a finding of any violation of U.S. federal or state securities laws.

The Letter of Transmittal, Certificates and any other required documents should be sent or delivered by each stockholder of Anadigics or such stockholder’s broker, dealer, commercial bank, trust company or other nominee to the Depositary at one of its addresses set forth below:

You may direct questions and requests for assistance to the Information Agent at the address and telephone number set forth below.
