PRELIMINARY PROXY STATEMENT—SUBJECT TO COMPLETION

[—], 2019

Dear Acacia stockholder:

We are pleased to invite you to attend a special meeting of the stockholders of Acacia Communications, Inc., a Delaware corporation, which we refer to as “we,” “us,” “Acacia” or the “Company,” to be held on [—], 2019 at [—], Eastern time, at the offices of Wilmer Cutler Pickering Hale and Dorr LLP, 60 State Street, Boston, Massachusetts 02109.

On July 9, 2019, the Company announced that it had entered into an Agreement and Plan of Merger, dated as of July 8, 2019, which we refer to as the merger agreement, with Cisco Systems, Inc., a California corporation, which we refer to as Parent, and Amarone Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of Parent, which we refer to as Merger Sub, providing for the merger of Merger Sub with and into the Company, which we refer to as the merger, with the Company surviving the merger as a wholly owned subsidiary of Parent.

At the special meeting, you will be asked to consider and vote on the following matters:

• a proposal to adopt the merger agreement;

• a proposal to approve, on a nonbinding advisory basis, the compensation that may be payable to our named executive officers in connection with the merger as reported on the table on page [—] of the accompanying proxy statement, including the associated narrative discussion; and

• a proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies to approve the proposal to adopt the merger agreement.

Stockholders will also act on any other business that may properly come before the special meeting.

If the merger is consummated, each share of Company common stock issued and outstanding immediately prior to the effective time of the merger will, other than as provided below, be converted into the right to receive $70.00 in cash, without interest and subject to deduction for any required withholding tax. We refer to this consideration per share of Company common stock to be paid in the merger as the merger consideration. The following shares of Company common stock will not be converted into the right to receive the merger consideration in connection with the merger: (a) shares held by any of our stockholders who do not vote in favor of the proposal to adopt the merger agreement and who otherwise properly exercise, and do not withdraw or lose, appraisal rights in accordance with Section 262 of the General Corporation Law of the State of Delaware, which we refer to as the DGCL, (b) shares held in the treasury of the Company and (c) shares owned by Parent or any direct or indirect wholly owned subsidiary of the Company or subsidiary of Parent.

The board of directors of the Company, which we refer to as the board of directors, has unanimously determined that the terms and conditions of the merger and the merger agreement are advisable, fair to and in the best interests of the Company and its stockholders and recommends that all Company stockholders vote in favor of the proposal to adopt the merger agreement. The board of directors made its determination after consultation with its legal and financial advisors and consideration of a number of factors.The board of directors recommends that you vote “FOR” approval of the proposal to adopt the merger agreement, “FOR” approval of the nonbinding advisory proposal regarding compensation that may be payable to our named executive officers in connection with the merger and “FOR” approval of the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies.

Approval of the proposal to adopt the merger agreement requires the affirmative vote of holders of a majority of the shares of Company common stock that are issued and outstanding as of the record date.

Your vote is very important.In order to ensure your representation at the special meeting, whether or not you plan to attend the special meeting, please complete, date, sign and return, as promptly as possible, the enclosed proxy card in the accompanying prepaid reply envelope, or submit your proxy by telephone or the Internet.If you properly sign your proxy card but do not mark the boxes showing how your shares should be voted on a matter, the shares represented by your properly signed proxy will be voted “FOR” approval of the proposal to adopt the merger agreement, “FOR” approval of the nonbinding advisory proposal regarding compensation that may be payable to our named executive officers in connection with the merger and “FOR” approval of the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies.You may revoke your proxy at any time before it is exercised at the special meeting by delivering a properly executed proxy card bearing a later date or a written revocation of your proxy to the Company’s Secretary before the start of the special meeting, submitting a later-dated proxy electronically via the Internet or telephonically, or by attending the special meeting and voting in person. Attending the special meeting will not, in itself, revoke a previously submitted proxy. To revoke a proxy in person at the special meeting, you must obtain a ballot and vote in person at the special meeting.The failure to vote your shares of Company common stock will have the same effect as a vote “AGAINST” approval of the proposal to adopt the merger agreement.

If your shares of Company common stock are held in “street name” by your bank, brokerage firm or other nominee, your bank, brokerage firm or other nominee will be unable to vote your shares of Company common stock without instructions from you. You should instruct your bank, brokerage firm or other nominee to vote your shares of Company common stock in accordance with the procedures provided by your bank, brokerage firm or other nominee.The failure to instruct your bank, brokerage firm or other nominee to vote your shares of Company common stock “FOR” approval of the proposal to adopt the merger agreement will have the same effect as voting “AGAINST” the proposal to adopt the merger agreement.

Under the DGCL, if the merger is completed, holders of Company common stock who do not vote in favor of adoption of the merger agreement and satisfy other conditions set forth in Section 262 of the DGCL will have the right to seek an appraisal by the Delaware Court of Chancery of the fair value of their shares. In order to exercise your appraisal rights, you must submit a written demand for an appraisal of your shares prior to the stockholder vote to adopt the merger agreement, you must not vote in favor of adoption of the merger agreement and you must comply with the procedures set forth in Section 262 of the DGCL and explained in the accompanying proxy statement.

In order to exercise your appraisal rights, you must submit a written demand for an appraisal of your shares prior to the stockholder vote to adopt the merger agreement, you must not vote in favor of adoption of the merger agreement and you must comply with the procedures set forth in Section 262 of the DGCL and explained in the accompanying proxy statement. See “Appraisal Rights” beginning on page [—] andAnnex D of the accompanying proxy statement.

WHETHER OR NOT YOU PLAN TO ATTEND THE SPECIAL MEETING, PLEASE COMPLETE, DATE, SIGN AND RETURN, AS PROMPTLY AS POSSIBLE, THE ENCLOSED PROXY CARD IN THE ACCOMPANYING PREPAID REPLY ENVELOPE, OR SUBMIT YOUR PROXY BY TELEPHONE OR THE INTERNET.

that may be payable to our named executive officers in connection with the merger and “FOR”the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies.

Goldman Sachs provided advisory services and its opinion for the information and assistance of the board of directors in connection with its consideration of the merger. The Goldman Sachs opinion is not a recommendation as to how any holder of Company common stock should vote with respect to the merger or any other matter. Pursuant to an engagement letter between the Company and Goldman Sachs, the Company has agreed to pay Goldman Sachs a transaction fee that is estimated, based on the information available as of the date of the announcement of the transaction, to be approximately $33,600,000, $3,000,000 of which became payable upon the presentation by Goldman Sachs to the board of directors of the final results of the study Goldman Sachs undertook to determine whether it was able to render a fairness opinion, and the remainder of which is contingent upon the consummation of the merger.

Interests of Certain Persons in the Merger (Page [—])

In considering the recommendation of the board of directors with respect to the merger agreement, you should be aware that the Company’s directors and executive officers have interests in the merger that may be different from, or in addition to, the interests of our stockholders generally, as more fully described below. The board of directors was aware of these interests and considered them, among other matters, in reaching the determination that the terms and conditions of the merger and the merger agreement were advisable, fair to and in the best interests of the Company and its stockholders and in making their recommendations regarding adoption of the merger and the merger agreement as described in “The Merger — Reasons for the Merger; Recommendation of the Board of Directors” beginning on page [—]. These interests include:

• conversion at the effective time of each Company stock option that is outstanding, vested and unexercised immediately prior to the effective time of the merger into the right to receive an amount in cash, without interest, equal to the excess, if any, of the merger consideration over the exercise price per share of such stock option subject to deduction for any required withholding tax; provided that, in the event that the exercise price of any such vested stock option is equal to or greater than the merger consideration, such stock option will be canceled at the effective time, without any consideration being payable in respect thereof and have no further force or effect;

• conversion at the effective time of each Company stock option that is outstanding and unvested immediately prior to the effective time of the merger into the right to receive an amount in cash, without interest, equal to the excess, if any, of the merger consideration over the exercise price per share of such stock option, subject to deduction for any required withholding tax, payable to the extent, and at the applicable times, such unvested stock option would have become vested under the vesting schedule in place for such stock option immediately prior to the effective time, including under the terms of the Company’s Amended and Restated Severance and Change in Control Benefits Plan, which we refer to as the CIC plan, and any scheduled retention agreement after giving effect to any applicable employment offer documents received from Parent; provided that, in the event that the exercise price of any such unvested stock option is equal to or greater than the merger consideration, such stock option will be canceled at the effective time, without any consideration being payable in respect thereof and have no further force or effect;

• conversion at the effective time of each Company restricted stock unit, or RSU, and Company performance-based restricted stock unit, or PRSU, that is outstanding and vested and has not been settled immediately prior to the effective time of the merger (which includes certain PRSUs with a total stockholder return performance metric that will become vested based on actual results as of the closing of the merger and certain RSUs that will become vested at the closing of the merger) into the right to receive an amount in cash, without interest, equal to the merger consideration, subject to deduction for any required withholding tax;

• conversion at the effective time of each RSU and PRSU that is outstanding and unvested immediately prior to the effective time of the merger into the right to receive an amount in cash, without interest, equal to the merger consideration, subject to deduction for any required withholding tax, payable to the extent, and at the applicable times, such unvested RSU or PRSU would have become vested under the vesting schedule in place for such RSU or PRSU immediately prior to the effective time, including under the terms of the CIC plan and any scheduled retention agreement after giving effect to any applicable employment offer documents received from Parent;

• potential severance and acceleration of unvested equity compensation awards upon certain types of termination of employment following the closing of the merger;

• accelerated vesting of RSUs held bynon-employee directors of the Company; and

• continued indemnification and liability insurance for directors and officers following completion of the merger.

See “The Merger — Interests of Certain Persons in the Merger” beginning on page [—] for additional information.

Approval of Compensation Payable to Named Executive Offices in Connection with the Merger (page [—])

In accordance with Section 14A of the Securities Exchange Act of 1934, as amended, which we refer to as the Exchange Act, and Rule14a-21(c) under the Exchange Act, we are providing stockholders with the opportunity to cast a nonbinding advisory vote with respect to compensation that may be payable to our named executive officers in connection with the merger, as reported on the table on page [—], including the associated narrative discussion. The board of directors recommends that you vote “FOR” approval of the nonbinding advisory proposal regarding compensation that may be payable to our named executive officers in connection with the merger.

Approval of the proposal regarding compensation that may be payable to our named executive officers in connection with the merger requires the approval of a majority of the votes cast on this proposal. Approval of this proposal is not a condition to completion of the merger. The vote with respect to compensation that may be payable to our named executive officers in connection with the merger is an advisory vote and will not be binding on us. Therefore, regardless of whether stockholders approve the compensation that may be payable to our named executive officers in connection with the merger, if the merger agreement is adopted by the stockholders and the merger is completed, such compensation will still be paid to our named executive officers to the extent payable in accordance with the terms of such compensation.

U.S. Federal Income Tax Consequences of the Merger (Page [—])

The exchange of shares of Company common stock for cash pursuant to the merger will generally be a taxable transaction to U.S. holders and certainnon-U.S. holders for U.S. federal income tax purposes. A U.S. holder (or anon-U.S. holder that is subject to U.S. federal income tax on its gain from the merger) who exchanges shares of Company common stock for cash in the merger generally will recognize gain or loss for U.S. federal income tax purposes in an amount equal to the difference, if any, between the amount of cash received (determined before deduction of any applicable withholding taxes) with respect to such shares and the stockholder’s adjusted tax basis in such shares. This may also be a taxable transaction under applicable state, local and/or foreign income or other tax laws. You should read“The Merger—U.S. Federal Income Tax Consequences of the Merger”beginning on page [—] for the definition of “U.S. holder” and“non-U.S. holder” and a more detailed discussion of the U.S. federal income tax consequences of the merger. You should also consult your tax advisor for a complete analysis of the effect of the merger on your U.S. federal, state and local and/or foreign taxes.

Regulatory Approvals (Page [—])

The merger is subject to the reporting and waiting period requirements of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, which we refer to as the HSR Act, and obtaining antitrust approval in specified foreign jurisdictions, including Austria, China and Germany. Under the terms of the merger agreement, the merger cannot be consummated if any governmental entity of competent jurisdiction has issued, promulgated or entered any judgment, writ, decree, stipulation, determination, decision, legal or arbitration award, settlement or consent agreement, charge, ruling, injunction, restraining order or other order (whether temporarily, preliminary or permanently in effect), or has enacted any law, statute, constitution, resolution, ordinance, code, permit, rule, regulation, ruling or requirement that prohibits, makes illegal or enjoins the consummation of the merger.

The Merger Agreement (Page [—])

Merger Consideration (Page [—])

If the merger is completed, each share of Company common stock, other than the excluded shares, will be converted into the right to receive $70.00 in cash, without interest and subject to deduction for any required withholding tax.

Treatment of Company Equity Awards and Employee Stock Purchase Plan (Page [—])

Each Company stock option that is outstanding, vested and unexercised immediately prior to the effective time of the merger will be canceled at the effective time and converted into the right to receive an amount in cash, without interest, equal to the excess, if any, of the merger consideration over the exercise price per share of such stock option; provided that, in the event that the exercise price of any such vested stock option is equal to or greater than the merger consideration, such stock option will be canceled at the effective time, without any consideration being payable in respect thereof and have no further force or effect.

Each Company stock option that is outstanding and unvested immediately prior to the effective time of the merger will be canceled at the effective time and converted into the right to receive an amount in cash, without interest, equal to the excess, if any, of the merger consideration over the exercise price per share of such stock option payable to the extent, and at the applicable times, such unvested option would have become vested under the vesting schedule in place for such stock option immediately prior to the effective time, including under the terms of the CIC plan, and any scheduled retention agreement after giving effect to any applicable employment offer documents received from Parent; provided that, in the event that the exercise price of any such unvested stock option is equal to or greater than the merger consideration, such stock option will be canceled at the effective time, without any consideration being payable in respect thereof and have no further force or effect.

Each RSU and PRSU that is outstanding and vested and has not been settled immediately prior to the effective time of the merger (which includes certain PRSUs with a total stockholder return performance metric that will become vested based on actual results as of the closing of the merger and certain RSUs that will become vested at the closing of the merger) will be canceled at the effective time and converted into the right to receive an amount in cash, without interest, equal to the merger consideration.

Each RSU and PRSU that is outstanding and unvested immediately prior to the effective time of the merger will be canceled at the effective time and converted into the right to receive an amount in cash, without interest, equal to the merger consideration payable to the extent, and at the applicable times, such unvested RSU or PRSU would have become vested under the vesting schedule in place for such RSU or PRSU immediately prior to the effective time, including under the terms of the CIC plan and any scheduled retention agreement after giving effect to any applicable employment offer documents received from Parent.

Each cash payment for the stock options, RSUs and PRSUs described above will be subject to deduction for any applicable withholding taxes.

As soon as practicable following the date of the merger agreement, the Company will take all actions with respect to the Company’s Amended and Restated 2016 Employee Stock Purchase Plan, which we refer to as the Company ESPP, that are required to provide that, (i) with respect to any offering period in effect as of the date of the merger agreement, no employee who is not a participant in the Company ESPP as of the date of the merger agreement may become a participant in the Company ESPP and no participant may increase the percentage amount of his or her payroll deduction election from that in effect on the date of the merger agreement for such offering period; (ii) subject to the consummation of the merger, the Company ESPP will terminate effective immediately prior to the effective time of the merger; (iii) if the offering period in effect as of the date of the

7

merger agreement terminates prior to the effective time of the merger, then the Company ESPP will be suspended and no new offering period will be commenced under the Company ESPP prior to the termination of the merger agreement; and (iv) if any offering period in effect as of the date of the merger agreement is still in effect at the effective time of the merger, then the last day of such offering period will be accelerated to the business day prior to the closing date of the merger, and each participant will be entitled to a cash payment to equal to (A) (1) the per share merger consideration times (2) the number of shares of Company common stock that the participant’s accumulated payroll deductions as of such date could purchase at the “Option Price” (as defined in the Company ESPP), where the per share merger consideration is treated as the fair market value of the Company common stock on the last day of the applicable offering period for purposes of determining the Option Price, and where the number of shares that could be purchased is subject to the limitations set forth in the Company ESPP, minus (B) the result of multiplying such number of shares by such Option Price.

Restrictions on Solicitation of Other Offers (Page [—])

Under the merger agreement, during the period beginning on the date of the merger agreement until the earlier of the effective time of the merger or the termination of the merger agreement, the board of directors, the Company and its subsidiaries will not, and will direct their respective representatives not to, directly or indirectly:

• solicit, initiate or knowingly encourage, knowingly facilitate or knowingly induce the making, submission or public announcement of any inquiry, indication of interest, proposal or offer that constitutes, or could reasonably be expected to lead to, an acquisition proposal;

• enter into, participate in, maintain or continue any communications (except to provide written notice as to the existence of these restrictions and to clarify the terms and conditions of any acquisition proposal) or negotiations regarding, or deliver or make available to any person anynon-public information with respect to any inquiry, indication of interest, proposal or offer that constitutes, or could reasonably be expected to lead to, an acquisition proposal;

• agree to, accept, approve, endorse or recommend (or publicly propose or announce any intention to agree to, accept, approve, endorse or recommend) any acquisition proposal;

• enter into any agreement in principle, letter of intent, term sheet or any other agreement, understanding or contract (whether binding or not) contemplating or otherwise relating to any acquisition proposal (other than confidentiality agreements that are permitted pursuant to the merger agreement);

• submit any acquisition proposal to the vote of any securityholders of the Company or any of its subsidiaries;

• approve any transaction, or any third party becoming an “interested stockholder,” under Section 203 of the DGCL; or

• resolve, propose or agree to do any of the foregoing, in each case except under specified circumstances set forth in the merger agreement.

Notwithstanding these restrictions, if, at any time prior to the time that the Company’s stockholders approve the adoption of the merger agreement, the Company or any of its representatives receives an unsolicited, written acquisition proposal that the board of directors concludes in good faith (after consultation with its outside legal counsel and a financial advisor of national standing) is, or could reasonably be expected to lead to, a superior proposal, the Company may:

• enter into discussions with such person regarding such acquisition proposal; and

• deliver or make available to such personnon-public information regarding the Company and its subsidiaries.

8

However, prior to taking any of the actions listed above, the Company must have complied with the following:

• none of the Company, its subsidiaries or any of their respective representatives has violated thenon-solicitation and related provisions contained in the merger agreement in any material respect;

• the board of directors must first conclude in good faith (after consultation with its outside legal counsel) that the failure to take such action would be inconsistent with its fiduciary obligations to the Company’s stockholders under applicable laws;

• prior to making available any materialnon-public information, the Company must first receive from such person an executed confidentiality agreement that contains terms that are no less favorable in any material respect to the Company than the terms in the confidentiality agreement between the Company and Parent but does not have to contain any “standstill” provisions and that does not include any exclusive right to negotiate with such person or having the effect of restricting the Company from fulfilling its obligations under the merger agreement; and

• prior to or contemporaneously with delivering or making available anynon-public information, the Company must concurrently deliver to Parent suchnon-public information to the extent suchnon-public information has not been previously delivered or made available to Parent by the Company.

You should read “The Merger Agreement — Restrictions on Solicitation of Other Offers” beginning on page [—] for the definitions of “acquisition proposal” and “superior proposal.”

Restrictions on Changes of Recommendation to Company Stockholders (Page [—])

Under the merger agreement, the board of directors must submit the merger agreement to the Company’s stockholders for adoption and must recommend that the Company’s stockholders vote in favor of adopting the merger agreement. The merger agreement provides that neither the board of directors, nor any committee thereof, may:

• fail to include the board of directors’ recommendation with respect to the merger agreement in this proxy statement;

• withhold, withdraw, qualify, amend or modify, or publicly propose or resolve to withhold, withdraw, qualify, amend or modify in a manner adverse to Parent or Merger Sub, the board of directors’ recommendation with respect to the merger agreement; or

• adopt, accept, approve, endorse or recommend, or publicly propose to adopt, approve, endorse or recommend, any acquisition proposal (each of the foregoing, referred to as a change of recommendation).

However, nothing in the merger agreement will prevent the board of directors from effecting a change of recommendation in connection with a superior proposal or the Company from terminating the merger agreement to enter into a definitive agreement to accept a superior proposal if:

• the approval of the Company’s stockholders of the adoption of the merger agreement has not yet been obtained;

• the Company has not breached in any material respect its obligations with respect to calling and conducting the special meeting of the Company’s stockholders and has not breached thenon-solicitation and related provisions of the merger agreement;

• a superior proposal has been submitted to the Company, has not been withdrawn and continues to be a superior proposal;

9

• the Company has given Parent at least four business days’ prior written notice of its intention to take such action along with certain information relating to such superior proposal;

• if requested by Parent, the Company makes its representatives available to discuss and negotiate in good faith with Parent’s representatives any modifications to the terms and conditions of the merger agreement that Parent desires to propose such that such superior proposal would no longer be a superior proposal in comparison to the revised terms of the merger agreement proposed by Parent;

• within such four-business day period, Parent has not made a written, binding and irrevocable offer that the board of directors has concluded in good faith (following consultation with its outside legal counsel and a financial advisor of national standing) to be at least as favorable to the Company’s stockholders as such superior proposal; and

• the board of directors has concluded in good faith (following consultation with its outside legal counsel) that, in light of the superior proposal and any modifications to the merger agreement proposed by Parent, the failure to effect a change of recommendation and terminate the merger agreement would be inconsistent with its fiduciary obligations to the Company’s stockholders under applicable law.

In addition, nothing in the merger agreement will prevent the board of directors from effecting a change of recommendation for a reason unrelated to an acquisition proposal if:

• the approval of the Company’s stockholders of the adoption of the merger agreement has not yet been obtained;

• the Company has not breached in any material respect its obligations with respect to calling and conducting the special meeting of the Company’s stockholders and has not breached thenon-solicitation and related provisions of the merger agreement;

• the board of directors has concluded in good faith (after consultation with its outside legal counsel) that, in light of an intervening event (after taking into account the results of any discussions with Parent and any proposed modifications of the merger agreement, as contemplated by the merger agreement), the failure to make a change of recommendation would be inconsistent with its fiduciary obligations to the Company’s stockholders under applicable law (provided that in no event will any of the following, in and of itself, constitute or be deemed an intervening event: (a) any determination by the board of directors that the amount payable by Parent in the merger is not sufficient, (b) the Company exceeding any earnings projections or predictions made by the Company (whether or not publicly announced) or securities or financial analysts and any resulting analyst upgrades of the Company’s securities or any change in the trading price of its common stock, (c) any facts, events or circumstances resulting from any breach of the merger agreement by the Company or (d) the receipt, existence or terms of any acquisition proposal or any matter relating thereto or the consequences thereof);

• the Company has given Parent at least four business days’ prior written notice of its intention to take such action along with certain information relating to such intervening event;

• if requested by Parent, the Company has made its representatives available during such four-business day period to discuss with Parent’s representatives the facts and circumstances underlying such proposed change in recommendation and any modifications to the terms and conditions of the merger agreement that Parent desires to propose that would obviate the need for the board of directors to effect a change of recommendation for an intervening event; and

• if within such four-business day period, Parent has not made a written, binding and irrevocable offer that the board of directors concludes in good faith (after consultation with its outside legal counsel and a financial advisor of national standing) would obviate the need for the board of directors to effect such change of recommendation (with the merger agreement providing that (a) the board of directors must

10

convene a meeting to consider any such offer by Parent promptly following the receipt thereof, (b) the board of directors will not effect a change of recommendation for four business days after receipt by Parent of the notice of an intervening event and (c) any material change in the facts, events or circumstances related to the intervening event will require a new notice of an intervening event to Parent and a newtwo-business day period and discussion process).

In addition, if the board of directors decides to terminate the merger agreement with Parent following receipt of a superior proposal upon the terms summarized above or Parent terminates the merger agreement following a change of recommendation under certain scenarios, the Company must pay the applicable termination fee as described beginning on page [—] under “The Merger Agreement — Termination Fee.”

You should read “The Merger Agreement — Restrictions on Changes of Recommendation to Company Stockholders” beginning on page [—] for the definitions of “change of recommendation” and “intervening event.”

Termination (Page [—])

The merger agreement may be terminated under specified circumstances set forth in the merger agreement, including, among others, the following:

• by mutual written consent of the Company and Parent;

• by either the Company or Parent if (a) the merger has not been completed on or before the end date (provided that a party will not be permitted to terminate the merger agreement due to the nonoccurrence of the closing before the end date if the failure to close is principally caused by the breach by such party of the merger agreement), (b) a governmental entity has issued a final and nonappealable order or taken any other final and nonappealable action, permanently restraining, enjoining or otherwise prohibiting the merger (provided that this right to terminate the merger agreement will not be available to any party that has materially breached its obligations under the merger agreement in any manner that principally caused the existence of such order or action in any material respect), (c) the approval of the adoption of the merger agreement by holders of Company

11

common stock entitled to vote thereon is not obtained or (d) upon a breach of any covenants or other obligations on the part of the other party set forth in the merger agreement, or if any representation or warranty of the other party has become inaccurate, in each case such that the closing condition with respect to the other party regarding the accuracy of representations and warranties or compliance with covenants and other obligations would not be satisfied;

• by Parent, if a triggering event occurs; or

• by the Company, to accept a superior proposal and concurrently enter into a definitive agreement for such superior proposal;provided that the Company has complied in all material respects with thenon-solicitation and related provisions under the merger agreement and makes a payment to Parent of a termination fee of $120 million.

You should read “The Merger Agreement — Termination” beginning on page [—] for the definitions of “end date” and “triggering event.”

Termination Fee (Page [—])

Subject to certain limitations, the Company will be required to pay Parent a termination fee equal to $120 million if the merger agreement is terminated:

• by Parent because of the occurrence of a triggering event;

• by either Parent or the Company because (a) the holders of Company common stock failed to approve adoption of the merger agreement at the special meeting of the Company’s stockholders or any adjournment or postponement thereof or (b) the closing did not occur on or prior to the end date, in each case at a time that Parent would have been entitled to terminate the merger agreement because of the occurrence of a triggering event;

• by the Company in order to accept a superior proposal;provided that the Company concurrently enters into a definitive agreement for such superior proposal; or

• by either Parent or the Company because (a) the holders of Company common stock failed to approve adoption of the merger agreement at the special meeting of the Company’s stockholders or any adjournment or postponement thereof, (b) the closing did not occur on or prior to the end date and such termination of the merger agreement occurred prior to obtaining approval of the adoption of the merger agreement at the special meeting of the Company’s stockholders or (c) the Company breached a representation or warranty contained in the merger agreement or failed to perform any of its covenants or other obligations contained in the merger agreement, which breach or failure to perform or comply would give rise to the failure to satisfy one of certain conditions to completion of the merger, and, in each such case, (i) any person will have publicly announced an acquisition proposal (or an acquisition proposal will have become publicly known) prior to such termination (unless publicly withdrawn prior to such termination) and (ii) within 12 months of such termination either an acquisition with respect to the Company is consummated or the Company enters into a definitive agreement with respect to an acquisition that is ultimately consummated (even if consummated following such12-month period).

In addition, under an Addendum to Master Purchase Agreements that was entered into between the Company, Parent and a wholly owned subsidiary of Parent in connection with the merger agreement, Parent may be required to pay to the Company a special payment with respect to the termination of the merger agreement under specified circumstances, as described in the section entitled “Other Agreements — Addendum to Master Purchase Agreements” beginning on page [—].

Other Agreements(Page [—])

Voting Agreements (Page [—])

On July 8, 2019, concurrently with the execution of the merger agreement, Parent entered into voting agreements with each of Murugesan Shanmugaraj, Benny Mikkelsen, Christian Rasmussen and Mehrdad Givehchi (including certain entities holding common shares of the Company on their behalf), pursuant to which such stockholders agreed, among other things, to vote their shares of Company common stock in favor of the adoption of the merger agreement and any matter that would reasonably be expected to facilitate the merger, and agreed to certain restrictions on their ability to take actions with respect to the Company and their shares of Company common stock. As of the record date, these stockholders beneficially owned approximately [—]% of the issued and outstanding shares of Company common stock. A copy of the form of voting agreement is attached asAnnex C to this proxy statement.

Addendum to Master Purchase Agreements (Page [—])

In connection with the execution of the merger agreement, on July 8, 2019, the Company, Parent and Cisco International B.V., a wholly owned subsidiary of Parent, also entered into an Addendum to the Master Purchase Agreements by and between such parties, which we refer to as the addendum, pursuant to which Parent and Cisco International B.V. agreed to purchase certain percentages, ranging from 70% to 100% depending on product and date, of Parent’s and Cisco International B.V.’s requirements for certain of the Company’s existing products at agreed upon prices and to negotiate in good faith with respect to Parent’s and Cisco International B.V.’s future purchase of a majority of its requirements for certain of the Company’s future products subject to certain additional requirements. Parent and Cisco International B.V. may elect to terminate the addendum upon any change in control of the Company or the termination of the merger agreement by (a) the Company in order to accept a superior proposal, (b) Parent because a triggering event has occurred or because the Company breached a representation or warranty contained in the merger agreement or failed to perform any of its covenants or other obligations contained in the merger agreement, which breach or failure to perform or comply would give rise to the failure to satisfy certain conditions to the completion of the merger, or (c) by the Company or Parent because the closing did not occur on or before the end date, in each case at a time that the merger agreement was terminable for the reasons set forth in clauses (a) and (b) above. In addition, the addendum provides that, subject to certain conditions, Parent would be required to make a payment to the Company in the amount of $120 million if the merger agreement is terminated for the failure to obtain required regulatory approvals when all other conditions to closing have been satisfied.

Market Price and Dividend Data of Company Common Stock (Page [—])

The Company common stock is listed on the Nasdaq Global Select Market under the ticker symbol “ACIA.” On July 8, 2019, the last full trading day prior to the public announcement of the merger, the closing price of the Company common stock on the Nasdaq Global Select Market was $48.06 per share. On[—], 2019, the latest practicable trading day before the printing of this proxy statement, the closing price of the Company common stock on the Nasdaq Global Select Market was $[—] per share. You are encouraged to obtain current market quotations for Company common stock in connection with voting your shares of Company common stock.

The Company has never paid cash dividends on the Company common stock.

Appraisal Rights (Page [—])

If the merger is completed, record holders of Company common stock as of the record date who submit a written demand for appraisal before the vote is taken on the adoption of the merger agreement, do not vote in favor of the adoption of the merger agreement, hold their shares of Company common stock continuously through the

13

effective time of the merger and otherwise comply with the procedures set forth in Section 262 of the DGCL may elect to pursue their appraisal rights to receive, in lieu of the $70.00 per share merger consideration, an amount in cash equal to the judicially determined “fair value” of their shares, which fair value will be determined as of the effective time of the merger and could be more or less than, or the same as, the per share merger consideration for the Company common stock. For a summary of the procedures set forth in Section 262 of the DGCL, see “Appraisal Rights” beginning on page [—]. An executed proxy that is not marked “AGAINST” or “ABSTAIN” with respect to the adoption of the merger agreement will be voted “FOR” the adoption of the merger agreement and the stockholder submitting that proxy will lose the right to seek an appraisal of his, her or its shares of Company common stock.

A copy of Section 262 of the DGCL is included asAnnex D to this proxy statement. Failure to follow the procedures set forth in Section 262 of the DGCL will result in the loss of appraisal rights. We encourage you to read these provisions carefully and in their entirety.

ANY COMPANY STOCKHOLDER WHO WISHES TO EXERCISE APPRAISAL RIGHTS OR WHO WISHES TO PRESERVE HIS, HER OR ITS RIGHT TO DO SO SHOULD REVIEWANNEX D CAREFULLY AND SHOULD CONSULT HIS, HER OR ITS LEGAL ADVISORS, SINCE FAILURE TO TIMELY AND FULLY COMPLY WITH THE PROCEDURES SET FORTH THEREIN WILL RESULT IN THE LOSS OF SUCH RIGHTS.

Delisting and Deregistration of Company Common Stock (Page [—])

If the merger is consummated, the Company common stock will be delisted from the Nasdaq Global Select Market and deregistered under the Exchange Act. Accordingly, following the consummation of the merger, we would no longer file periodic reports with the Securities and Exchange Commission, or the SEC.

Conduct of Our Business if the Merger is Not Completed (Page [—])

In the event that the merger agreement is not adopted by our stockholders or if the merger is not completed for any other reason, our stockholders will not receive any consideration from Parent or Merger Sub for their shares of Company common stock. Instead, we would remain an independent public company, our common stock would continue to be listed and traded on the Nasdaq Global Select Market and our stockholders would continue to be subject to the same risks and opportunities to which they currently are subject with respect to their ownership of Company common stock. If the merger is not completed, there can be no assurance as to the effect of these risks and opportunities on the future value of our shares, including the risk that the market price of Company common stock may decline to the extent that the current market price of our stock reflects a market assumption that the merger will be completed. If the merger is not completed, our business could be disrupted, including our ability to retain and hire key personnel, potential adverse reactions or changes to our business relationships and uncertainty surrounding our future plans and prospects.

QUESTIONS AND ANSWERS ABOUT THE SPECIAL MEETING AND THE MERGER

The following questions and answers are intended to address briefly some commonly asked questions regarding the merger, the merger agreement and the special meeting. These questions and answers may not address all questions that may be important to you as a Company stockholder. Please refer to the “Summary” and the more detailed information contained elsewhere in this proxy statement, the annexes to this proxy statement and the documents referred to in this proxy statement, which you should read carefully and in their entirety. You may obtain the information incorporated by reference in this proxy statement without charge by following the instructions under “Where You Can Find More Information” beginning on page [—].

Q. What is the proposed transaction and what effects will it have on the Company?

A. The proposed transaction is the acquisition of the Company by Parent pursuant to the merger agreement. If the proposal to adopt the merger agreement is approved by our stockholders and the other closing conditions under the merger agreement are satisfied or waived, Merger Sub will merge with and into the Company, with the Company being the surviving corporation. As a result of the merger, the Company will become a subsidiary of Parent and will no longer be a publicly held corporation, and you will no longer have any interest in our future earnings or growth. In addition, the Company common stock will be delisted from the Nasdaq Global Select Market and deregistered under the Exchange Act, and we will no longer file periodic reports with the SEC.

Q. What will I receive if the merger is consummated?

A. Upon completion of the merger, you will be entitled to receive the per share merger consideration of $70.00 in cash, without interest and subject to deduction for any required withholding tax, for each share of Company common stock that you own, unless you are entitled to and have properly demanded appraisal under Section 262 of the DGCL. For example, if you own 1,000 shares of Company common stock, you will receive $70,000 in cash in exchange for your shares of Company common stock, without interest and subject to deduction for any required withholding tax. You will not receive any shares of the capital stock in the surviving corporation.

Q. How does the per share merger consideration compare to the market price of Company common stock prior to announcement of the merger?

A. The merger consideration of $70.00 per share of Company common stock represents an approximately 46% premium to the closing price of the Company’s common stock on the Nasdaq Global Select Market on July 8, 2019, the last full trading day prior to the public announcement of the merger.

Q. What will holders of Company equity awards receive if the merger is consummated?

A. Each Company stock option that is outstanding, vested and unexercised immediately prior to the effective time of the merger will be canceled at the effective time and converted into the right to receive an amount in cash, without interest, equal to the excess, if any, of the merger consideration over the exercise price per share of such stock option;provided that, in the event that the exercise price of any such vested stock option is equal to or greater than the merger consideration, such stock option will be canceled at the effective time, without any consideration being payable in respect thereof and have no further force or effect.

Each Company stock option that is outstanding and unvested immediately prior to the effective time of the merger will be canceled at the effective timeand converted into the right to receive an amount in cash, without interest, equal to the excess, if any, of the merger consideration over the exercise price per share of such stock option payable to the extent, and at the applicable times, such unvested option would have become vested under the vesting schedule in place for such stock option immediately prior to the effective

15

time, including under the terms of the CIC plan, and any scheduled retention agreement after giving effect to any applicable employment offer documents received from Parent;provided that, in the event that the exercise price of any such unvested stock option is equal to or greater than the merger consideration, such stock option will be canceled at the effective time, without any consideration being payable in respect thereof and have no further force or effect.

Each RSU and PRSU that is outstanding and vested and has not been settled immediately prior to the effective time of the merger (which includes certain PRSUs with a total stockholder return performance metric that will become vested based on actual results as of the closing of the merger and certain RSUs that will become vested at the closing of the merger) will be canceled at the effective timeand converted into the right to receive an amount in cash, without interest, equal to the merger consideration.

Each RSU and PRSU that is outstanding and unvested immediately prior to the effective time of the merger will be canceled at the effective timeand converted into the right to receive an amount in cash, without interest, equal to the merger consideration payable to the extent, and at the applicable times, such unvested RSU or PRSU would have become vested under the vesting schedule in place for such RSU or PRSU immediately prior to the effective time, including under the terms of the CIC plan and any scheduled retention agreement after giving effect to any applicable employment offer documents received from Parent.

Each cash payment for the options, RSUs and PRSUs described above will be subject to deduction for any applicable withholding taxes.

Q. What will happen to the Company’s employee stock purchase plan?

A. As soon as practicable following the date of the merger agreement, the Company will take all actions with respect to the Company ESPP, that are required to provide that, (i) with respect to any offering period in effect as of the date of the merger agreement, no employee who is not a participant in the Company ESPP as of the date of the merger agreement may become a participant in the Company ESPP and no participant may increase the percentage amount of his or her payroll deduction election from that in effect on the date of the merger agreement for such offering period; (ii) subject to the consummation of the merger, the Company ESPP will terminate effective immediately prior to the effective time of the merger; (iii) if the offering period in effect as of the date of the merger agreement terminates prior to the effective time of the merger, then the Company ESPP will be suspended and no new offering period will be commenced under the Company ESPP prior to the termination of the merger agreement; and (iv) if any offering period in effect as of the date of the merger agreement is still in effect at the effective time of the merger, then the last day of such offering period will be accelerated to the business day prior to the closing date of the merger, and each participant will be entitled to a cash payment to equal to (A) (1) the per share merger consideration times (2) the number of shares of Company common stock that the participant’s accumulated payroll deductions as of such date could purchase at the “Option Price” (as defined in the Company ESPP), where the per share merger consideration is treated as the fair market value of the Company common stock on the last day of the applicable offering period for purposes of determining the Option Price, and where the number of shares that could be purchased is subject to the limitations set forth in the Company ESPP, minus (B) the result of multiplying such number of shares by such Option Price.

Q. How does the board of directors recommend that I vote?

A. The board of directors recommends that you vote “FOR” approval of the proposal to adopt the merger agreement, “FOR” approval of the nonbinding advisory proposal regarding compensation that may be payable to our named executive officers in connection with the merger and “FOR” approval of the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies.

16

Q. Why is the board of directors recommending that I vote “FOR” approval of the proposal to adopt the merger agreement?

A. After careful consideration of various factors described in the section entitled “The Merger — Reasons for the Merger; Recommendation of the Board of Directors,” the board of directors, by a unanimous vote of all directors:

• determined and declared that the terms and conditions of the merger agreement, the merger and the other transactions contemplated thereby, on the terms and subject to the conditions set forth in the merger agreement, are advisable, fair to and in the best interests of the Company and its stockholders;

• adopted and approved the merger agreement, the merger and the other transactions contemplated by the merger agreement; and

• determined that it is advisable and in the best interests of the Company for the board of directors to submit the merger agreement to the Company’s stockholders for adoption, directed that the merger agreement be submitted to the Company’s stockholders at a special meeting of the Company’s stockholders for their adoption and recommended that the Company’s stockholders adopt the merger agreement.

Q. When do you expect the merger to be consummated?

A. We are working towards completing the merger as soon as possible. Assuming timely satisfaction of necessary closing conditions, including the approval by our stockholders of the proposal to adopt the merger agreement and regulatory approvals, we currently anticipate that the merger will be consummated during the second half of Parent’s 2020 fiscal year, or between January 26, 2020 and July 25, 2020.

Q. What happens if the merger is not consummated?

A. If the merger agreement is not adopted by the stockholders of the Company or if the merger is not consummated for any other reason, the stockholders of the Company would not receive any payment for their shares of Company common stock in connection with the merger. Instead, the Company would remain an independent public company, and the Company common stock would continue to be listed and traded on the Nasdaq Global Select Market. Under specified circumstances, the Company may be required to pay to Parent a termination fee as described in the section entitled “The Merger Agreement — Termination Fee” beginning on page [—]. In addition, under the addendum Parent may be required to pay to the Company a special payment with respect to the termination of the merger agreement under specified circumstances, as described in the section entitled “Other Agreements — Addendum to Master Purchase Agreements” beginning on page [—].

Q. Is the merger expected to be taxable to me?

A. Yes. The exchange of shares of Company common stock for cash pursuant to the merger will generally be a taxable transaction to U.S. holders and certainnon-U.S. holders for U.S. federal income tax purposes. A U.S. holder (or anon-U.S. holder that is subject to U.S. federal income tax on its gain from the merger) who exchanges shares of Company common stock for cash in the merger generally will recognize gain or loss for U.S. federal income tax purposes in an amount equal to the difference, if any, between the amount of cash received (determined before deduction of any applicable withholding taxes) with respect to such shares and the stockholder’s adjusted tax basis in such shares. This may also be a taxable transaction under applicable state, local and/or foreign income or other tax laws. You should read “The Merger — U.S. Federal Income Tax Consequences of the Merger” beginning on page [—] for the definition of “U.S. holder” and“non-U.S. holder” and a more detailed discussion of the U.S. federal income tax consequences of the merger. Because individual circumstances may differ, you should also consult your tax advisor for a complete analysis of the effect of the merger on your U.S. federal, state and local and/or foreign taxes.

17

Q. Do any of the Company’s directors or officers have interests in the merger that may differ from or be in addition to my interests as a stockholder?

A. Yes. In considering the recommendation of the board of directors with respect to the proposal to adopt the merger agreement, you should be aware that our directors and executive officers have interests in the merger that may be different from, or in addition to, the interests of our stockholders generally. The board of directors was aware of and considered these interests, among other matters, in evaluating and negotiating the merger agreement and the merger, and in recommending that the merger agreement be adopted by the stockholders of the Company. See “The Merger — Interests of Certain Persons in the Merger” beginning on page [—].

Q. Why am I receiving this proxy statement and proxy card or voting instruction form?

A. You are receiving this proxy statement and proxy card or voting instruction form in connection with the solicitation of proxies by the board of directors for use at the special meeting because you owned shares of Company common stock as of the record date for the special meeting. This proxy statement describes matters on which we urge you to vote and is intended to assist you in deciding how to vote your shares of Company common stock with respect to such matters.

Q. When and where is the special meeting?

A. The special meeting of stockholders of the Company will be held on [—], 2019 at [—], Eastern time, at the offices of Wilmer Cutler Pickering Hale and Dorr LLP, 60 State Street, Boston, Massachusetts 02109.

Q. What am I being asked to vote on at the special meeting?

A. You are being asked to consider and vote on:

• a proposal to adopt the merger agreement that provides for the acquisition of the Company by Parent;

• a proposal to approve, on an advisory basis, the compensation that may be payable to our named executive officers in connection with the merger as reported on the table on page [—], including the associated narrative discussion; and

• a proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the proposal to adopt the merger agreement.

Q. What vote is required for the Company’s stockholders to approve the proposal to adopt the merger agreement?

A. The adoption of the merger agreement requires the affirmative vote of the holders of a majority of the shares of Company common stock that are issued and outstanding as of the record date. Pursuant to voting agreements entered into on July 8, 2019 between Parent and each of Murugesan Shanmugaraj, Benny Mikkelsen, Christian Rasmussen and Mehrdad Givehchi (including certain entities holding shares of Company common stock on their behalf), such stockholders agreed, among other things, to vote their shares of Company common stock in favor of the adoption of the merger agreement and any matter that would reasonably be expected to facilitate the merger. As of the record date, these stockholders beneficially owned approximately [—]% of the issued and outstanding shares of Company common stock.

Because the affirmative vote required to approve the proposal to adopt the merger agreement is based upon the total number of outstanding shares of Company common stock, if you fail to submit a proxy or to vote in person at the special meeting, or if you vote “ABSTAIN”, or if you do not provide your bank, brokerage firm or other nominee with voting instructions, it will have the same effect as a vote “AGAINST” the proposal to adopt the merger agreement.

18

Q. What vote is required for the Company’s stockholders to approve the proposal regarding compensation that may be payable to our named executive officers in connection with the merger and the proposal to adjourn the special meeting, if necessary or appropriate?

A. Approval of the proposals regarding compensation that may be payable to our named executive officers in connection with the merger and adjournment of the special meeting, if necessary or appropriate, require the affirmative vote of a majority of the votes cast by the holders of all of the shares present or represented at the special meeting and voting on each of these proposals.

If you vote “ABSTAIN” on the proposal regarding compensation that may be payable to our named executive officers in connection with the merger or the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies, this will have no effect on these proposals. If you fail to submit a proxy or to vote in person at the special meeting, or if you do not provide your bank, brokerage firm or other nominee with voting instructions, your shares of Company common stock will not be voted on these proposals, and thus will have no effect on these proposals.

Q. Why am I being asked to cast a nonbinding advisory vote to approve compensation that may be payable to the Company’s named executive officers in connection with the merger?

A. The SEC’s rules require us to seek a nonbinding advisory vote with respect to certain payments that will be made to our named executive officers in connection with the merger.

Q. What will happen if stockholders do not approve the compensation that may be payable to our named executive officers in connection with the merger at the special meeting?

A. Approval of compensation payable under existing agreements with the Company and, in certain cases, new agreements with Parent that our named executive officers may receive in connection with the merger is not a condition to completion of the merger. The vote with respect to such compensation is an advisory vote and will not be binding on us. Therefore, regardless of whether stockholders approve such compensation, if the merger agreement is adopted by the stockholders and the merger is completed, this compensation will still be paid to our named executive officers to the extent payable in accordance with the terms of such agreements.

Q. Who can vote at the special meeting?

A. All of our holders of Company common stock of record as of the close of business on [—], 2019, the record date for the special meeting, are entitled to receive notice of, and to vote at, the special meeting. Each holder of Company common stock is entitled to cast one vote on each matter properly brought before the special meeting for each share of Company common stock that such holder owned as of the record date. As of the record date, there were approximately [—] shares of our common stock issued and outstanding held collectively by [—] stockholders of record.

Q. What is a “brokernon-vote”?

A. Banks, brokerage firms or other nominees who hold shares in “street name” for customers have the authority to vote on “discretionary” proposals when they have not received instructions from beneficial owners. However, banks, brokerage firms or other nominees are precluded from exercising their voting discretion with respect to approvingnon-discretionary matters, such as the proposal to adopt the merger agreement, the proposal to approve the nonbinding advisory proposal regarding compensation that may be payable to our named executive officers in connection with the merger and the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies, and, as a result, absent specific instructions from the beneficial owner of such shares of Company common stock, banks, brokerage firms or other nominees are not empowered to vote those shares of Company common stock onnon-discretionary matters. Shares held

19

by banks, brokerage firms or nominees that are present in person or by proxy at the special meeting but with respect to which the broker or other stockholder of record is not instructed by the beneficial owner of such shares how to vote on a particular proposal and the broker does not have discretionary voting power on such proposal are referred generally as “brokernon-votes.” Because none of the proposals to be voted on at the special meeting are routine matters for which brokers may have discretionary authority to vote, the Company does not expect any brokernon-votes at the special meeting.

Q. What constitutes a quorum for the special meeting?

A. A quorum is necessary to adopt the merger agreement and approve the proposal regarding compensation that may be payable to our named executive officers in connection with the merger at the special meeting. The presence at the special meeting, in person or by proxy, of the holders of a majority of the shares of Company common stock that are issued and outstanding at the close of business on the record date constitutes a quorum for the purposes of the special meeting. Abstentions and “brokernon-votes” (as described above) will be counted as present for the purpose of determining whether a quorum is present. Because none of the proposals to be voted on at the special meeting are routine matters for which brokers may have discretionary authority to vote, the Company does not expect any brokernon-votes at the special meeting. The special meeting may be adjourned whether or not a quorum is present.

Q. How do I vote?

A. If you are a stockholder of record, you may vote your shares of Company common stock on matters presented at the special meeting in any of the following ways:

• in person — you may attend the special meeting and cast your vote there; or

• by proxy — stockholders of record have a choice of having their shares voted by proxy by submitting a proxy in one of the following ways:

• over the Internet — the website for Internet proxy submission is on your proxy card;

• by using a toll-free telephone number noted on your proxy card; or

• by signing, dating and returning the enclosed proxy card in the accompanying prepaid reply envelope.

If you hold your shares of Company common stock in “street name,” please refer to the instructions provided by your bank, brokerage firm or other nominee to see which of the above choices are available to you. Please note that if you are a beneficial owner of shares of Company common stock held in “street name” and wish to vote in person at the special meeting, you must provide a legal proxy from your bank, brokerage firm or other nominee at the special meeting.

A control number, located on your proxy card, is designed to verify your identity and allow you to submit a proxy for your shares of Company common stock, and to confirm that your voting instructions have been properly recorded when submitting a proxy over the Internet or by telephone.

Q. What is the difference between holding shares as a stockholder of record and in “street name”?

A. If your shares of Company common stock are registered directly in your name with our transfer agent, Computershare Trust Company, N.A., you are considered, with respect to those shares of Company common stock, as the “stockholder of record.” This proxy statement, and your proxy card, have been sent directly to you by the Company.

If your shares of Company common stock are held through a bank, brokerage firm or other nominee, you are considered the beneficial owner of shares of Company common stock held in “street name.” In that case, this proxy statement has been forwarded to you by your bank, brokerage firm or other nominee who is

20

considered, with respect to those shares of Company common stock, the stockholder of record. As the beneficial owner of shares of Company common stock held in “street name,” you have the right to direct your bank, brokerage firm or other nominee how to vote your shares of Company common stock by following their instructions for voting.

Q. If my shares of Company common stock are held in “street name” by my bank, brokerage firm or other nominee, will my bank, brokerage firm or other nominee vote my shares of Company common stock for me?

A. Your bank, brokerage firm or other nominee will only be permitted to vote your shares of Company common stock if you instruct your bank, brokerage firm or other nominee how to vote. You should follow the procedures provided by your bank, brokerage firm or other nominee regarding the voting of your shares of Company common stock. If you do not instruct your bank, brokerage firm or other nominee to vote your shares of Company common stock, your shares of Company common stock will not be voted and the effect will be the same as a vote “AGAINST” the proposal to adopt the merger agreement and your shares of Company common stock will not have an effect on approval of the advisory proposal regarding compensation that may be payable to our named executive officers in connection with the merger or the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies.

Q. How can I change or revoke my proxy?

A. You have the right to revoke a proxy, whether delivered over the Internet, by telephone or by mail, at any time before it is exercised, by submitting a later-dated proxy through any of the methods available to you, by giving written notice of revocation to our Secretary at Acacia Communications, Inc., Three Mill and Main Place, Suite 400, Maynard, Massachusetts 01754, or by attending the special meeting and voting in person. Attending the special meeting will not, in itself, revoke a previously submitted proxy.

Q. What is a proxy?

A. A proxy is your legal designation of another person, referred to as a “proxy,” to vote your shares of Company common stock. The written document describing the matters to be considered and voted on at the special meeting is called a “proxy statement.” The document used to designate a proxy to vote your shares of Company common stock is called a “proxy card.” The board of directors has designated John F. Gavin and Janene I. Asgeirsson, and each of them singly, with full power of substitution, as proxies for the special meeting.

Q. If a stockholder gives a proxy, how will its shares of Company common stock be voted?

A. Regardless of the method you choose to submit your proxy, the individuals named on the enclosed proxy card, as your proxies, will vote your shares of Company common stock in the way that you indicate. When completing the Internet or telephone proxy processes or the enclosed proxy card, you may specify whether your shares of Company common stock should be voted for or against or to abstain from voting on all, some or none of the specific items of business to come before the special meeting.

If you properly sign your proxy card but do not mark the boxes showing how your shares of Company common stock should be voted on a matter, the shares represented by your properly signed proxy will be voted “FOR” the proposal to adopt the merger agreement, “FOR” approval of the nonbinding advisory proposal regarding compensation that may be payable to our named executive officers in connection with the merger and “FOR” the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies.

21

Q. How are votes counted?

A. With respect to the proposal to adopt the merger agreement, you may vote “FOR”, “AGAINST” or “ABSTAIN.” Abstentions and brokernon-votes will have the same effect as votes “AGAINST” the proposal to adopt the merger agreement.

With respect to the proposal regarding compensation that may be payable to our named executive officers in connection with the merger and the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies, you may vote “FOR”, “AGAINST” or “ABSTAIN.” Abstentions and brokernon-votes will have no effect on these proposals.

Q. What do I do if I receive more than one proxy or set of voting instructions?

A. If you hold shares of Company common stock in more than one account, you may receive more than one proxy or set of voting instructions relating to the special meeting. These should each be voted or returned separately in accordance with the instructions provided in this proxy statement in order to ensure that all of your shares of Company common stock are voted.

Q. What happens if I sell my shares of Company common stock before the special meeting?

A. The record date for stockholders entitled to vote at the special meeting is earlier than both the date of the special meeting and the consummation of the merger. If you transfer your shares of Company common stock after the record date but before the special meeting, unless special arrangements (such as provision of a proxy) are made between you and the person to whom you transfer your shares and each of you notifies the Company in writing of such special arrangements, you will retain your right to vote such shares at the special meeting but will transfer the right to receive the per share merger consideration to the person to whom you transfer your shares. You will also lose the ability to exercise appraisal rights in connection with the merger.

Q. Who will solicit and pay the cost of soliciting proxies?

A. The Company has engaged The Proxy Advisory Group, LLC to assist in the solicitation of proxies and provide related advice and informational support for the special meeting, for a services fee and the reimbursement of customary disbursements, which are not expected to exceed $20,000 in the aggregate. The Company will also indemnify The Proxy Advisory Group, LLC and its affiliates against certain claims, expenses, losses, damages, liabilities and judgments. The Company may also reimburse brokers, banks and other custodians, nominees and fiduciaries representing beneficial owners of shares of Company common stock for their expenses in forwarding soliciting materials to beneficial owners of Company common stock and in obtaining voting instructions from those owners. Our directors, officers and employees may also solicit proxies by telephone, by facsimile, by mail, on the Internet or in person. They will not be paid any additional amounts for soliciting proxies.

Q. What do I need to do now?

A. Even if you plan to attend the special meeting, after carefully reading and considering the information contained in this proxy statement, please submit your proxy promptly to ensure that your shares are represented at the special meeting. If you hold your shares of Company common stock in your own name as the stockholder of record, please submit a proxy for your shares of Company common stock by (a) completing, signing, dating and returning the enclosed proxy card in the accompanying prepaid reply envelope, (b) using the telephone number printed on your proxy card or (c) using the Internet proxy instructions printed on your proxy card. If you decide to attend the special meeting and vote in person, your vote by ballot will revoke any proxy previously submitted. If you are a beneficial owner of shares of Company common stock held in “street name,” please refer to the instructions provided by your bank, brokerage firm or other nominee to see which of the above choices are available to you.

22

Q. Should I send in my stock certificates now?

A. No. A letter of transmittal will be mailed to you promptly, and in any event within three business days, after the effective time of the merger, describing how you should surrender your shares of Company common stock for the per share merger consideration. If your shares of Company common stock are held in “street name” by your bank, brokerage firm or other nominee, you will receive instructions from your bank, brokerage firm or other nominee as to how to effect the surrender of your “street name” shares of Company common stock in exchange for the per share merger consideration.Please do NOT return your stock certificate(s) with your proxy.

Q. What should I do if I have lost my stock certificate?

A. If you have lost your stock certificate, please contact our transfer agent, Computershare Trust Company, N.A., at (877)373-6374, to obtain replacement certificates.

Q. What rights do I have if I oppose the merger?

A. Stockholders of record as of the record date are entitled to exercise appraisal rights under the DGCL only if they do not vote for the adoption of the merger agreement and otherwise follow the procedures and satisfy the requirements specified in Section 262 of the DGCL. A copy of Section 262 of the DGCL is attached asAnnex D to this proxy statement. See “Appraisal Rights” beginning on page [—].

Q. Are there any other risks to me from the merger that I should consider?

A. Yes. There are risks associated with all business combinations, including the merger. See “Cautionary Statement Concerning Forward-Looking Information” beginning on page [—].

Q. Who can help answer my other questions?

CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING INFORMATION

This proxy statement, and the documents to which we refer you in this proxy statement, as well as information included in oral statements or other written statements made or to be made by us, contain a number of “forward-looking statements,” including all statements relating directly or indirectly to the timing or likelihood of completing the merger to which this proxy statement relates, litigation and other information with respect to our plans and strategies. Any statements contained herein that are not statements of historical fact may be deemed to be forward-looking statements. Without limiting the foregoing, the words “believes,” “intends,” “anticipates,” “plans,” “estimates,” “expects” and similar expressions are intended to identify forward-looking statements. There are a number of important factors that could cause actual events or our actual results to differ materially from those indicated by such forward-looking statements, including the occurrence of any event or proceeding that could give rise to the termination of the merger agreement; the inability to complete the merger due to the failure of the closing conditions to be satisfied; the outcome of any legal proceedings that may be instituted in connection with the merger; and the other factors described in the Company’s Annual Report on Form10-K for the year ended December 31, 2018 and its most recent quarterly report filed with the SEC. In addition, any forward-looking statements represent our estimates only as of the date they were made and should not be relied upon as representing our estimates as of any subsequent date. Except to the extent otherwise required by law, while we may elect to update forward-looking statements at some point in the future, we specifically disclaim any obligation to do so, even if our estimates change.

24

THE SPECIAL MEETING

Time, Place and Purpose of the Special Meeting

This proxy statement is being furnished to our stockholders as part of the solicitation of proxies by the board of directors for use at the special meeting to be held on [—], 2019, starting at [—], Eastern time, at the offices of Wilmer Cutler Pickering Hale and Dorr LLP, 60 State Street, Boston, Massachusetts 02109, or at any adjournment thereof. At the special meeting, holders of Company common stock will be asked to approve the proposal to adopt the merger agreement, to approve the nonbinding advisory proposal regarding compensation that may be payable to our named executive officers in connection with the merger and to approve the proposal to adjourn the special meeting, if necessary or appropriate, for the purpose of soliciting additional proxies if there are insufficient votes at the time of the special meeting to approve the proposal to adopt the merger agreement.

Our stockholders must approve the proposal to adopt the merger agreement in order for the merger to be consummated. If our stockholders fail to approve the proposal to adopt the merger agreement, the merger will not be consummated. A copy of the merger agreement is attached asAnnex A to this proxy statement, which we encourage you to read carefully in its entirety.

Record Date and Quorum

We have fixed the close of business on [—], 2019 as the record date for the special meeting, and only holders of record of Company common stock on the record date are entitled to vote at the special meeting. You are entitled to receive notice of, and to vote at, the special meeting if you owned shares of Company common stock at the close of business on the record date. On the record date, there were [—] shares of Company common stock outstanding and entitled to vote. Each share of Company common stock entitles its holder to one vote on all matters properly coming before the special meeting.

A majority of the shares of Company common stock that are issued and outstanding at the close of business on the record date, present in person or represented by proxy, at the special meeting constitutes a quorum for the purposes of the special meeting. Shares of Company common stock represented at the special meeting but not voted, including shares of Company common stock for which a stockholder directs voting “ABSTAIN”, as well as brokernon-votes, will be counted for purposes of establishing a quorum. Because none of the proposals to be voted on at the special meeting are routine matters for which brokers may have discretionary authority to vote, the Company does not expect any brokernon-votes at the special meeting. A quorum is necessary to adopt the merger agreement and approve the proposal regarding compensation that may be payable to our named executive officers in connection with the merger at the special meeting. Once a share of Company common stock is represented at the special meeting, it will be counted for the purpose of determining a quorum at the special meeting and any recess or adjournment of the special meeting. However, if a new record date is set for the adjourned special meeting, then a new quorum will have to be established. In the event that a quorum is not present at the special meeting, it is expected that the special meeting will be adjourned or recessed.

Attendance

Only stockholders of record or their duly authorized proxies or beneficial owners with proof of ownership have the right to attend the special meeting. If your shares of Company common stock are held through a bank, brokerage firm or other nominee, please bring to the special meeting a copy of your brokerage statement evidencing your beneficial ownership of Company common stock. If you are the representative of a corporate or institutional stockholder, you must present proof that you are the representative of such stockholder.

Vote Required

Approval of the proposal to adopt the merger agreement requires the affirmative vote of the holders of a majority of the shares of Company common stock that are issued and outstanding as of the record date. For the proposal to

25

adopt the merger agreement, you may vote “FOR”, “AGAINST” or “ABSTAIN.” Voting “ABSTAIN” will not be counted as a vote cast in favor of the proposal to adopt the merger agreement but will count for the purpose of determining whether a quorum is present.If you fail to submit a proxy or to vote in person at the special meeting, or if you vote “ABSTAIN”, it will have the same effect as a vote “AGAINST” the proposal to adopt the merger agreement.

If your shares of Company common stock are registered directly in your name with our transfer agent, Computershare Trust Company, N.A., you are considered, with respect to those shares of Company common stock, the “stockholder of record.” This proxy statement and proxy card have been sent directly to you by the Company.

If your shares of Company common stock are held through a bank, brokerage firm or other nominee, you are considered the beneficial owner of shares of Company common stock held in “street name.” In that case, this proxy statement has been forwarded to you by your bank, brokerage firm or other nominee who is considered, with respect to those shares of Company common stock, the stockholder of record. As the beneficial owner of shares of Company common stock held in “street name,” you have the right to direct your bank, brokerage firm or other nominee how to vote your shares by following their instructions for voting. If you hold your shares of Company common stock in “street name,” please contact your bank, brokerage firm or other nominee for their instructions on how to vote your shares. Please note that if you are a beneficial owner of shares of Company common stock held in “street name” and wish to vote in person at the special meeting, you must provide a legal proxy from your bank, brokerage firm or other nominee at the special meeting.

Under the rules of the Nasdaq Stock Market, banks, brokerage firms or other nominees who hold shares in “street name” for customers have the authority to vote on “discretionary” proposals when they have not received instructions from beneficial owners. However, banks, brokerage firms or other nominees are precluded from exercising their voting discretion with respect to approvingnon-discretionary matters, such as the proposal to adopt the merger agreement, the proposal to approve the nonbinding advisory proposal regarding compensation that may be payable to our named executive officers in connection with the merger and the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies, and, as a result, absent specific instructions from the beneficial owner of such shares of Company common stock, banks, brokerage firms or other nominees are not empowered to vote those shares of Company common stock onnon-discretionary matters. Shares held by banks, brokerage firms or nominees that are present in person or by proxy at the special meeting but with respect to which the broker or other stockholder of record is not instructed by the beneficial owner of such shares how to vote on a particular proposal and the broker does not have discretionary voting power on such proposal are referred generally as “brokernon-votes.” These brokernon-votes will be counted for purposes of determining a quorum, but will have the same effect as a vote “AGAINST” the proposal to adopt the merger agreement. Because none of the proposals to be voted on at the special meeting are routine matters for which brokers may have discretionary authority to vote, the Company does not expect any brokernon-votes at the special meeting.

Approval of the advisory proposal regarding compensation that may be payable to our named executive officers in connection with the merger and approval of the proposal to adjourn the special meeting, if necessary or appropriate, for the purpose of soliciting additional proxies, require a majority of the votes cast on each of these proposals. For the nonbinding advisory proposal regarding compensation that may be payable to our named executive officers in connection with the merger and the proposal to adjourn the special meeting, if necessary or appropriate, you may vote “FOR”, “AGAINST” or “ABSTAIN.” For purposes of each of these proposals, if you fail to submit a proxy or to vote in person at the special meeting, or if you have given a proxy and vote “ABSTAIN”, the shares of Company common stock will not be counted in respect of, and will not have any effect on, the proposal.

26

If you are a stockholder of record, you may vote your shares of Company common stock on matters presented at the special meeting in any of the following ways:

• in person — you may attend the special meeting and cast your vote there; or

• by proxy — stockholders of record have a choice of having their shares voted by proxy by submitting a proxy in one of the following ways:

• over the Internet — the website for Internet proxy submission is on your proxy card;

If you are a beneficial owner of Company common stock held in “street name,” you will receive instructions from your bank, brokerage firm or other nominee that you must follow in order to have your shares of Company common stock voted. Those instructions will identify which of the above choices are available to you in order to have your shares voted. Please note that if you are a beneficial owner of Company common stock held in “street name” and wish to vote in person at the special meeting, you must provide a legal proxy from your bank, brokerage firm or other nominee.

If you choose to submit your proxy over the Internet or by telephone, your proxy card submission must be made by the time the special meeting begins. If you choose to submit your proxy by mailing a proxy card, your proxy card must be received by the time the special meeting begins.Please do not send in your stock certificates with your proxy card. Following the consummation of the merger, a separate letter of transmittal will be mailed to you that will enable you to surrender your stock certificates and receive the per share merger consideration.

If you vote by proxy, regardless of the method you choose to submit a proxy, the individuals named as your proxies on the enclosed proxy card, and each of them, with full power of substitution, will vote your shares of Company common stock in the way that you indicate. When completing the Internet or telephone proxy processes or the enclosed proxy card, you may specify whether your shares of Company common stock should be voted for or against or to abstain from voting on all, some or none of the specific items of business to come before the special meeting.

If you properly sign your proxy card but do not mark the boxes showing how your shares of Company common stock should be voted on a matter, the shares of Company common stock represented by your properly signed proxy will be voted “FOR” the proposal to adopt the merger agreement, “FOR” approval of the nonbinding advisory proposal regarding compensation that may be payable to our named executive officers in connection with the merger and “FOR” the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies.

Our Board’s Recommendation

The board of directors has unanimously determined that the terms and conditions of the merger and the merger agreement are advisable, fair to and in the best interests of the Company and its stockholders and recommends that all Company stockholders vote in favor of the proposal to adopt the merger agreement. The board of directors made its determination after consultation with its legal and financial advisors and consideration of a number of factors, as described in “The Merger — Reasons for the Merger; Recommendation of the Board of Directors” beginning on page [—]. The board of directors recommends that you vote“FOR” approval of the proposal to adopt the merger agreement,“FOR” approval of the nonbinding advisory proposal regarding compensation that may be payable to our named executive officers in connection with the merger and“FOR” approval of the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies.

Shares Owned by Our Directors and Executive Officers

As of the record date, the directors and executive officers of the Company beneficially owned and were entitled to vote, in the aggregate, [—] shares of Company common stock, representing approximately [—]% of the issued and outstanding shares of Company common stock on the record date. The directors and executive officers have informed the Company that they currently intend to vote all of their shares of Company common stock “FOR” the proposal to adopt the merger agreement, “FOR” approval of the nonbinding advisory proposal regarding compensation that may be payable to our named executive officers in connection with the merger and “FOR” the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies. In addition, the shares described above include shares beneficially owned by Murugesan Shanmugaraj, Benny Mikkelsen, Christian Rasmussen and Mehrdad Givehchi (including certain entities holding shares of Company common stock on their behalf) and such stockholders are obligated, pursuant to voting agreements entered into on July 8, 2019 between Parent and each of such stockholders, to vote such shares, representing approximately [—]% of the issued and outstanding shares of Company common stock on the record date, in favor of the adoption of the merger agreement and any matter that would reasonably be expected to facilitate the merger.

Proxies and Revocation

Any stockholder of record entitled to vote at the special meeting may submit a proxy by telephone, over the Internet, or by returning the enclosed proxy card in the accompanying prepaid reply envelope, or may vote in person at the special meeting. If your shares of Company common stock are held in “street name” by your bank, brokerage firm or other nominee, you should instruct your bank, brokerage firm or other nominee on how to vote your shares of Company common stock using the instructions provided by your bank, brokerage firm or other nominee. If you fail to submit a proxy or to vote in person at the special meeting, or if you vote “ABSTAIN”, or if you do not provide your bank, brokerage firm or other nominee with voting instructions, your shares of Company common stock will not be voted on the proposal to adopt the merger agreement, which will have the same effect as a vote “AGAINST” the proposal to adopt the merger agreement.

You have the right to revoke a proxy, whether delivered over the Internet, by telephone or by mail, at any time before it is exercised, by submitting a later-dated proxy through any of the methods available to you, by giving written notice of revocation to our Secretary, which must be received by the Company at Three Mill and Main Place, Suite 400, Maynard, Massachusetts 01754 by the time the special meeting begins, or by attending the special meeting and voting in person. Attending the special meeting will not, in itself, revoke a previously submitted proxy.

Adjournments and Recesses

Although it is not currently expected, the special meeting may be adjourned or recessed, including for the purpose of soliciting additional proxies, if there are insufficient votes at the time of the special meeting to

28

approve the proposal to adopt the merger agreement or if a quorum is not present at the special meeting. Other than an announcement to be made at the special meeting of the time, date and place of an adjourned meeting, an adjournment generally may be made without notice. Any adjournment or recess of the special meeting for the purpose of soliciting additional proxies will allow the Company’s stockholders who have already sent in their proxies to revoke them at any time prior to their use at the special meeting as adjourned or recessed.

Stockholder List

A list of our stockholders entitled to vote at the special meeting will be available for examination by any of our stockholders at the special meeting. For 10 days prior to the special meeting, this stockholder list will be available for inspection by any stockholder for any purpose germane to the special meeting during ordinary business hours at our corporate offices located at Three Mill and Main Place, Suite 400, Maynard, Massachusetts 01754.

Anticipated Date of Completion of the Merger

We are working towards completing the merger as soon as possible. Assuming timely satisfaction of necessary closing conditions, including the approval by our stockholders of the proposal to adopt the merger agreement, we currently anticipate that the merger will be consummated during the second half of Parent’s 2020 fiscal year, or between January 26, 2020 and July 25, 2020.

Appraisal Rights

If the merger is completed, record holders of Company common stock as of the record date who submit a written demand for appraisal before the vote is taken on the adoption of the merger agreement, do not vote in favor of the adoption of the merger agreement, hold their shares of Company common stock continuously through the effective time of the merger and otherwise comply with the procedures set forth in Section 262 of the DGCL may elect to pursue their appraisal rights to receive, in lieu of the $70.00 per share merger consideration, an amount in cash equal to the judicially determined “fair value” of their shares, which fair value will be determined as of the effective time of the merger and could be more or less than, or the same as, the per share merger consideration for the common stock. For a summary of the procedures set forth in Section 262 of the DGCL, see “Appraisal Rights” beginning on page [—]. An executed proxy that is not marked “AGAINST” or “ABSTAIN” will be voted “FOR” the adoption of the merger agreement and the stockholder submitting that proxy will lose the right to seek an appraisal of his, her or its shares of Company common stock.

A copy of Section 262 of the DGCL is included asAnnex D to this proxy statement. Failure to follow the procedures set forth in Section 262 of the DGCL will result in the loss of appraisal rights. We encourage you to read these provisions carefully and in their entirety.

ANY COMPANY STOCKHOLDER WHO WISHES TO EXERCISE APPRAISAL RIGHTS OR WHO WISHES TO PRESERVE HIS, HER OR ITS RIGHT TO DO SO SHOULD REVIEWANNEX D CAREFULLY AND SHOULD CONSULT HIS, HER OR ITS LEGAL ADVISORS, SINCE FAILURE TO TIMELY AND FULLY COMPLY WITH THE PROCEDURES SET FORTH THEREIN WILL RESULT IN THE LOSS OF SUCH RIGHTS.

Directors and Officers of the Surviving Corporation

The directors of Merger Sub immediately prior to the effective time of the merger will be the initial directors of the surviving corporation. The officers of Merger Sub immediately prior to the effective time of the merger will be the initial officers of the surviving corporation.

Background of the Merger

The board of directors, together with members of the Company’s senior management, regularly reviews and assesses the Company’s operations, financial condition, and industry developments in the context of the Company’s strategic plans and, in connection with this review and assessment, periodically considers strategic acquisitions, strategic alliances, business combinations and other strategic alternatives.

On May 15, 2017, Raj Shanmugaraj, the President and Chief Executive Officer of the Company, had dinner with the Chief Executive Officer of a company that we refer to as “Party A” at the invitation of Party A. During the dinner, the Chief Executive Officer of Party A reflected on the potential benefits of a strategic combination of the Company and Party A, but did not propose a transaction.

On October 12, 2017, Mr. Shanmugaraj and Benny Mikkelsen, a director and Founder and Chief Technology Officer of the Company, met with the Chief Executive Officer of Party A at the Company’s headquarters at Party A’s request. The Chief Executive Officer of Party A expressed Party A’s interest, subsequently affirmed in a written indication of interest, in acquiring the Company for cash and stock consideration valued at $65 per share, consisting of 30% cash and 70% common stock of Party A. Mr. Shanmugaraj and Mr. Mikkelsen responded that the Company had not been contemplating a sale, but noted that they would review the offer with the board of directors. On October 11, 2017, the closing price for Company common stock on the Nasdaq Global Select Market was $46.20 per share.

Frommid-October 2017 tomid-December 2017, the Company’s management engaged in discussions with the board of directors and Party A to evaluate the potential transaction. During this period, the Company executed a confidentiality agreement with Party A, which included a standstill provision that would terminate if the Company agreed to be acquired by a third party, and consulted Goldman Sachs & Co. LLC (“Goldman Sachs”) as its financial advisor and Wilmer Cutler Pickering Hale and Dorr LLP (“WilmerHale”) as its legal counsel. At a special meeting of the board of directors, held on December 18, 2017, a representative of WilmerHale reviewed the fiduciary duties of the board of directors and the board of directors instructed Goldman Sachs to respond to Party A’s proposal by informing Party A that it would need to make an offer above $70 per share to adequately compensate the Company for the risk of accepting Party A’s common stock as consideration and including a greater cash component. Representatives of Party A responded by saying they would discuss Party A’s strategic alternatives with their board, and thereafter abandoned the discussions. On December 15, 2017 (the immediately preceding trading day), the closing price for Company common stock on the Nasdaq Global Select Market was $39.38 per share.

Beginning in April 2018, representatives of the Company and a company we refer to as “Party B” engaged in preliminary discussions regarding a potential strategic combination, following a proposal by Party B to explore a

33

stock-for-stock combination. The Company concluded that the future growth prospects of Party B, whose stock price had declined significantly over the preceding 12 months, were not attractive. Neither party pursued the matter beyond preliminary due diligence, and discussions ended in June 2018.

On April 15, 2018, the U.S. Department of Commerce activated a denial order against ZTE Kangxun Telecom Co. Ltd., the Company’s largest customer by revenue, accounting for approximately 20% and 31% of the Company’s revenue during fiscal year 2018 and the first quarter of 2019, respectively, which we refer to as ZTE, based on adverse findings relating to the activities covered by ZTE’s 2016 settlement with the U.S. Department of Commerce to resolve charges of export control violations by ZTE. This denial order added ZTE to the “Denied Persons List,” which, among other things, prohibited the Company from making sales and providing certain services to ZTE. On April 16, 2018, the first trading day following announcement of this decision, the closing price of Company common stock was $25.63 per share, representing a 36% decrease from the closing price of $40.03 per share on the previous trading day.

On June 1, 2018, Mehrdad Givehchi, Founder and Vice President of Hardware and Software of the Company, spoke by telephone to a representative of a company that we refer to as “Party C” at the request of Party C. The representative of Party C expressed interest in exploring a strategic partnership or an acquisition involving the Company in order to more effectively serve one of Party C’s markets.

On June 4, 2018, after consulting with other members of the Company’s senior management, Mr. Givehchi called the representative of Party C and expressed management’s concern that Party C might be seeking to exploit the recent decline in the Company’s stock price due to events involving ZTE, which management did not believe was indicative of the Company’s long-term value. The representative of Party C assured Mr. Givehchi that Party C was not “bottom fishing,” and the parties agreed to negotiate a confidentiality agreement and to schedule a meeting among members of management of both parties. On June 1, 2018 (the immediately preceding trading day) the closing price for Company common stock on the Nasdaq Global Select Market was $32.79 per share.

On June 8, 2018, the Company and Party C executed a confidentiality agreement and scheduled the management meeting for June 20, 2018. The confidentiality agreement included a standstill provision that would terminate if the Company agreed to be acquired by a third party.

Also on June 8, 2018, ZTE and the U.S. Department of Commerce reached a new settlement imposing additional penalties and compliance measures upon ZTE, pursuant to which the denial order was terminated and ZTE was removed from the Denied Persons List effective July 13, 2018. This further U.S. Department of Commerce action authorized the Company to resume sales to, and related activities involving, ZTE.

On June 20, 2018, members of Company management attended a meeting at Party C’s headquarters with representatives of Party C at which management presented information regarding the Company’s business and discussed strategic partnership opportunities with Party C.

On June 22, 2018, Mr. Shanmugaraj received an email from a representative of Party C, indicating that the possibility of a strategic transaction with the Company would be discussed among senior management at Party C, and that Party C expected to follow up with the Company in the next couple of weeks with additional information.

On June 25, 2018, Mr. Shanmugaraj sent an email to the board of directors updating them on the discussions to date with Party C and notifying them that the Company might receive a proposal from Party C.

On July 2, 2018, the Company received a letter from Party C containing anon-binding expression of interest in acquiring the Company at a price of $41 per share. On June 29, 2018 (the immediately preceding trading day), the closing price for Company common stock on the Nasdaq Global Select Market was $ 34.81 per share.

34

On July 6, 2018, the board of directors held a telephonic special meeting to discuss the letter from Party C. At the meeting, a representative of WilmerHale reviewed the fiduciary duties of the board of directors regarding their consideration of a potential strategic transaction. After discussion of the proposed price, the perceived dislocation in the current trading price given the recent denial order against ZTE and the Company’s standalone prospects, the board of directors concluded that the offer was too low to accept or to justify further discussions. The board of directors instructed Mr. Shanmugaraj to reject the offer.

On July 10, 2018, Mr. Shanmugaraj telephoned a member of senior management of Party C and informed him that the expression of interest significantly undervalued the Company, and that the Company could not accept the proposed terms.

On July 13, 2018, a representative of Party C contacted Mr. Givehchi via text to request a meeting. After consultation with other members of Company management, Mr. Givehchi agreed to a meeting on July 17, 2018.

On July 17, 2018, Mr. Givehchi met with the representative of Party C over coffee at a location outside of Boston. The representative of Party C expressed regret that Party C had not presented a more attractive offer to the Company, noting that certain members of senior management of Party C had doubts about the competitive position of the Company and had been unwilling to agree to a higher price. The representative noted that Party C would continue to monitor the Company’s performance and guidance to determine whether a stronger case could be made in support of a transaction in the future. Later that day, Mr. Givehchi updated the board of directors on his conversation with the representative from Party C during a regularly scheduled meeting of the board of directors.

The Company periodically prepares and updates internal projections for internal budgeting and business planning purposes. On October 18, 2018, the board of directors held a regularly scheduled meeting at which senior management presented internal projections for the fiscal years ending December 31, 2019 through 2021 and engaged in a strategic discussion with the board of directors regarding the Company’s product roadmap and markets.

On February 23, 2019, following an introductory email from Bill Gartner, Senior Vice President and General Manager of the Optical Systems and Optics business unit of Parent, David Goeckeler, the Executive Vice President and General Manager of Parent’s Networking and Security Business, contacted Mr. Shanmugaraj by email requesting a telephone call. Parent had been a customer of the Company since 2015, accounting for 14% of the Company’s reported revenues for the fiscal year ended December 31, 2018, and would account for 18.1% of the Company’s reported revenues for the fiscal quarter ended March 31, 2019.

On February 25, 2019, Messrs. Goeckeler and Shanmugaraj spoke by telephone. Mr. Goeckeler expressed Parent’s interest in exploring strategic opportunities with the Company, ranging from partnership opportunities to the possibility of an acquisition. They agreed to meet to discuss further.

On March 1, 2019, Mr. Shanmugaraj received an email from Mr. Goeckeler in which he suggested, as the next step, anin-person meeting between Messrs. Goeckeler, Gartner, Shanmugaraj and Mikkelsen in the near future.

On March 5, 2019, Mr. Gartner contacted Mr. Shanmugaraj by text to request that he meet representatives of Parent for dinner the following night while both parties attended the Optical Fiber Communication Conference in San Diego.

On March 6, 2019, Mr. Shanmugaraj and Mr. Mikkelsen met Messrs. Goeckeler and Gartner for dinner. Mr. Goeckeler described Parent’s desire and rationale for pursuing a strategic partnership with the Company, and both parties concluded that it was worth exploring further and agreed to arrange a meeting with additional members of management from both companies. Thereafter, the Company and Parent scheduled a meeting at Parent’s offices in San Jose, California among members of management from both parties to be held on March 21, 2019.

35

On March 17, 2019, the Company and Parent executed a confidentiality agreement. The confidentiality agreement included a standstill provision that would terminate if the Company agreed to be acquired by a third party.

During March 2019, the Company prepared an update to the internal projections for the fiscal years ending December 31, 2019 through 2021 that had been presented to the board of directors on October 18, 2018 (which updated projections the Company referred to as the “Long-Range Plan”) in order to reflect subsequent developments, including a new product development program that had been launched internally in late December 2018.

On March 21, 2019, members of Company management attended a meeting at Parent’s offices in San Jose, California with representatives of Parent at which management presented information regarding the Company’s business, including the Long-Range Plan, and discussed strategic partnership opportunities with Parent.

On March 31, 2019, Mr. Goeckeler called Mr. Shanmugaraj to inform him that further evaluation of a potential transaction would be managed by Parent’s corporate development team, and that Rob Salvagno, Parent’s Vice President of Corporate Development and Cisco Investments, would be in contact with Mr. Shanmugaraj to continue the discussions.

On April 1, 2019, Mr. Salvagno called Mr. Shanmugaraj to communicate a proposal by Parent to acquire the Company at $62 per share. On March 29, 2019 (the immediately preceding trading day), the closing price for Company common stock on the Nasdaq Global Select Market was $57.35 per share.

On April 3, 2019, Mr. Shanmugaraj called Mr. Salvagno to inform him that Parent’s proposal did not reflect a sufficient premium to warrant further discussion with respect to a potential transaction. Mr. Shanmugaraj noted that the parties could continue to work together in the context of their commercial relationship.

On April 10, 2019, Mr. Salvagno called Mr. Shanmugaraj to inform him that Parent was increasing its offer to $67 per share. Mr. Shanmugaraj told Mr. Salvagno that he would discuss the offer with the board of directors and get back to him afterwards. On April 9, 2019, the closing price for Company common stock on the Nasdaq Global Select Market was $57.72 per share.

On April 11, 2019, a representative of Party C contacted Mr. Shanmugaraj by text to request a meeting on April 15, 2019.

On April 15, 2019, Mr. Shanmugaraj met the representative of Party C for lunch in Boston. The representative indicated that members of senior management of Party C had been discussing the potential strategic importance of the Company to Party C and wanted to gauge the Company’s interest in exploring a strategic transaction. Mr. Shanmugaraj expressed skepticism based on the prior acquisition proposal from Party C, but said he would keep an open mind with respect to any proposal that reflected the strategic value of the Company.

On April 17, 2019, the board of directors held a telephonic special meeting with members of senior management and a representative of WilmerHale present. Mr. Shanmugaraj described to the board of directors his discussions with Parent to date, including the $67 per share offer by Parent. John Gavin, the Chief Financial Officer of the Company, next reviewed the Long-Range Plan with the board of directors, and presented management’s assessment of potential risks to achieving the results forecast in the projections, including the potential weakening (and potential loss longer term) of the customer relationship with Parent if it shifted purchasing to a second source, sought to develop competitive technology internally or pursued an acquisition of a Company competitor in lieu of completing a transaction with the Company. The board of directors then compared the potential risks and benefits of pursuing a transaction with Parent versus other strategic alternatives, including continuing to operate on a standalone basis. One of the major risks to pursuing a transaction with Parent that the board of directors discussed was the potential that other customers might not view Parent as committed to serving as a long-term supplier of components to third parties and the potential implications on the ability to

36

receive regulatory approval for a transaction. One of the standalone alternatives discussed was an acquisition of assets from a company we refer to as “Party D” then under consideration by management. The board of directors noted that Parent’s proposal was not a significant premium over the current trading price of Company common stock, which had closed at $60.59 per share on April 16, 2019. The board of directors also discussed the fact that the Company would be making its quarterly earnings announcement in approximately two weeks, and expected to report strong results for the first quarter, exceeding analyst expectations and prior Company guidance. The board of directors concluded that Mr. Shanmugaraj should tell Parent that any further discussions should be deferred until after the upcoming earnings announcement.

On April 19, 2019, Mr. Shanmugaraj called Mr. Salvagno to inform him that the board of directors had concluded that further discussions should be deferred until after the Company’s upcoming earnings announcement.

During May 2019, there were several events reflecting worsening trade relations between China and the United States, including the failure of China and the United States to negotiate a trade deal prior to the May 9 deadline set by the United States, the imposition of additional tariffs by the United States the following day, the imposition of additional tariffs by China in response, and the addition of Huawei Technologies Co., Ltd. and certain of its affiliates, referred to collectively as Huawei, to the “Entity List” by the U.S. Department of Commerce. During May 2019, the closing price of the Company’s common stock on the Nasdaq Global Select Market declined from $60.45 per share on May 1 to $46.60 per share on May 31.

On May 2, 2019, the Company reported first quarter 2019 results, exceeding the high end of Company guidance on revenue,non-GAAP gross margin,non-GAAP net income andnon-GAAP diluted earnings per share, and held a call to discuss such results. On May 3, 2019, the closing price for Company common stock on the Nasdaq Global Select Market was $59.00 per share, as compared to the closing price of $60.55 per share on May 2, 2019, prior to the reporting of its first quarter results.

On May 3, 2019, a representative of Party C contacted Mr. Shanmugaraj by email to propose a meeting between Mr. Shanmugaraj and members of Party C’s senior management to explore strategic options.

On May 10, 2019, the board of directors held a telephonic special meeting with members of senior management and a representative of WilmerHale present. The board of directors discussed strategic alternatives to a transaction with Parent, including continuing to operate on a standalone basis and pursuing the asset acquisition discussed at the April 17, 2019 board of directors meeting. The Company’s management provided an updated assessment of the potential risks and benefits of remaining a standalone entity in light of recent market and customer developments, including the worsening trade relations between China and the United States and the potential weakening (and potential loss longer term) of the customer relationship with Parent if it shifted purchasing to a second source, sought to develop competitive technology internally or pursued an acquisition of a Company competitor in lieu of completing a transaction with the Company, as well as the continued volatility in the price of Company common stock, as witnessed by the price decline following the recent announcement of a successful first quarter. The board of directors authorized management to submit anon-binding indication of interest with respect to the potential acquisition of assets from Party D, but concluded that the board of directors should continue to discuss whether to pursue a transaction with Parent at the regularly scheduled board of directors meeting on May 16, 2019, and that management should be prepared to discuss its recommendation at that meeting.

On May 13, 2019, Mr. Shanmugaraj called the representative of Party C and informed the representative that the board of directors was skeptical of further engagement with Party C in light of the offer made the prior year, which the board of directors felt undervalued the Company significantly. Mr. Shanmugaraj told the representative that Party C should provide a firm proposal that shows they are serious about the strategic value of the Company before the Company would engage in further discussions. The representative of Party C acknowledged Mr. Shanmugaraj’s request and suggested a further discussion between Mr. Shanmugaraj and the Chief Executive Officer of Party C.

37

On May 14, 2019, Mr. Salvagno emailed Mr. Shanmugaraj to inquire about the status of the Company’s consideration of Parent’s proposal. Mr. Salvagno and Mr. Shanmugaraj then spoke by telephone the following day, and Mr. Shanmugaraj informed Mr. Salvagno that he would be working with the board of directors to prepare a response to the April 10, 2019 proposal.

On May 16, 2019, the board of directors held a regularly scheduled meeting with members of senior management and a representative of WilmerHale present for certain portions. Mr. Gavin reviewed the Company’s Long-Range Plan, which had been provided to Parent and previously discussed at the April 17, 2019 board of directors meeting, as well as recent customer, product and market developments that could affect projected revenue in the second half of 2020 and in 2021. Next, Mr. Shanmugaraj discussed management’s perspective on the potential risks and benefits of exploring a strategic transaction with Parent as an alternative to standalone operations and provided management’s recommendation that the Company further explore pursuing a strategic transaction with Parent, but in a manner designed not to result in any leaks to the market, given the customer concerns previously discussed. Mr. Shanmugaraj also described the outreach from and discussions with Party C, noting the uncertainty as to whether this would result in a viable alternative. The board of directors then discussed with management the potential risks to achieving the projected revenues in 2020 and 2021, the potential impact of worsening trade relations between China and the United States, the potential impact that recent actions by the U.S. Department of Commerce against Huawei could have on overall optical market timing and spending expectations in China and the potential risks and benefits of a strategic transaction with Parent. The board of directors then concluded that the Company should explore a potential strategic transaction with Parent, and instructed management that the next step should be to consult with financial and legal advisors on process, valuation and other matters. The board of directors then directed Mr. Shanmugaraj to communicate the Company’s interest in further discussions to Parent and authorized management to contact Goldman Sachs, which was selected based on its prior service as the Company’s financial advisor, to discuss its potential retention as the Company’s financial advisor for a potential sale transaction. The board of directors next discussed the status of the potential asset acquisition with Party D and whether to proceed in light of the decision to pursue further discussions with Parent. Messrs. Shanmugaraj and Gavin reported that the Company had been told its indication of interest was not in an appropriate value range, and that further engagement would not continue without an upward adjustment. They also reported that, as a result of an organizational change, Party D may be deferring further consideration of any strategic transaction for an indeterminate period of time. The board of directors concluded that the Company should delay any further activity with respect to the potential asset acquisition until it had an opportunity to further explore a transaction with Parent.

On May 17, 2019, a member of the board of directors and Company management each contacted Goldman Sachs to initiate discussions regarding its potential engagement as the Company’s financial advisor.

On May 20, 2019, Mr. Salvagno called Mr. Shanmugaraj to express concerns regarding recent global events and what impact they might have on the Company’s business, including recent actions by the U.S. Department of Commerce against Huawei, the applicability of existing and future tariffs imposed on the Company’s products and ongoing trade discussions between the U.S. and China governments and requested that Mr. Shanmugaraj provide Parent further information supporting the Company’s views that the potential impact of the actions with respect to Huawei would not adversely affect the Company’s business during the remainder of 2019.

Also on May 20, 2019, a representative of Party C called Mr. Shanmugaraj and again suggested that Mr. Shanmugaraj speak to the Chief Executive Officer of Party C by telephone in order to confirm Party C’s strategic interest in the Company and commitment to exploring a strategic transaction at valuation ranges that might be attractive. Following an exchange of emails between Mr. Shanmugaraj and the representative of Party C, Mr. Shanmugaraj agreed to a call between himself and the Chief Executive Officer of Party C, which was scheduled for May 24, 2019.

On May 23, 2019, members of Company management attended a telephonic meeting with representatives of Parent at which management presented information requested by Mr. Salvagno on the May 20, 2019 telephone

38

call. During the meeting, the Company’s management expressed its willingness to bring Parent’s $67 per share offer back before the board of directors for further discussion. In response, Parent noted that they needed to reassess their valuation in light of recent events and the information presented by the Company.

On May 24, 2019, Mr. Shanmugaraj spoke to the Chief Executive Officer of Party C by telephone. During the call, the Chief Executive Officer of Party C described Party C’s interest in the Company and his vision of the potential strategic benefits of a transaction between the two companies. At the end of the call, the Chief Executive Officer of Party C invited Mr. Shanmugaraj to a dinner to discuss next steps for exploring the possibility of a transaction. The dinner was scheduled for June 4, 2019.

On June 4, 2019, Mr. Shanmugaraj spoke to Mr. Salvagno, who communicated that Parent remained interested in pursuing a strategic transaction with the Company but, in light of recent market developments, was now prepared to offer only $62 per share. On June 3, 2019, the closing price for Company common stock on the Nasdaq Global Select Market was $46.50 per share.

Later on June 4, 2019, Mr. Shanmugaraj had dinner with the Chief Executive Officer of Party C, who reiterated that Party C was interested in continuing to explore a strategic transaction with the Company. The Chief Executive Officer expressed his expectation that Party C would submit an offer, but noted that Party C’s management would need additional financial and product information before Party C would be in the position to submit a proposal. Mr. Shanmugaraj agreed that the Company would work with Party C’s management to provide the requested information.

On June 6, 2019, the Company and Party C executed an amendment to the confidentiality agreement entered on June 8, 2018, which reinstated the standstill provision for an additional nine months and otherwise extended the term of the confidentiality agreement for an additional two years. The standstill provision, as amended, would terminate if the Company agreed to be acquired by a third party.

Later on June 6, 2019, members of Company management met with representatives of Party C to provide additional product and financial information. At this meeting, the members of Company management presented projections for 2019 through 2024, referred to as the June LRP, which reflected updates to the Long-Range Plan subsequently discussed at the June 8, 2019 board of directors meeting as described below.

On June 7, 2019, Mr. Shanmugaraj sent an email to Mr. Salvagno with an update on the board of director’s discussions, and indicating that the board of directors was continuing to consider Parent’s offer.

On June 8, 2019, the board of directors held a telephonic special meeting with members of senior management and representatives of Goldman Sachs and WilmerHale present for certain portions. Mr. Gavin provided the board of directors with the June LRP, which reflected projections for 2019 through and including 2024 proposed for use by Goldman Sachs to prepare financial analyses, noting that the three additional years of projections were added to facilitate a discounted cash flow analysis. Mr. Gavin described the detailed and updated review undertaken of the Company’s product roadmap, customer and market developments to prepare the projections, as well as the key assumptions underlying them. In particular, Mr. Gavin noted somewhat lower projected revenue in 2020 than in the prior projections for 2019 through 2021, based on a slower increase in the production rate for a new Company product due to the complexity of scaling initial production and the potential impact of trade and tariff discussions and actions by the U.S. Department of Commerce against Huawei on overall optical market timing and spending expectations in China. He also noted the impact these factors were anticipated to have on projected revenues in 2021, where growth rates were similar to those in the Long-Range Plan, but were growing from a lower base. Thereafter, the board of directors approved the June LRP for use by Goldman Sachs for purposes of its financial analyses. Representatives of Goldman Sachs reviewed an overview of public market data, a comparison of the Company’s internal projections against published analyst estimates (which analyst estimates were generally more conservative) and certain illustrative preliminary financial analyses. The representatives of Goldman Sachs then discussed certain process considerations with the board of directors,

39

including the merits of doing a targeted approach to other potential strategic partners that were likely to be interested in and capable of executing a transaction on acceptable terms. Mr. Shanmugaraj again emphasized the competitive harm that could result from a leak regarding any sale process, and provided his assessment of potential candidates for future outreach. Mr. Shanmugaraj identified the five additional parties (beyond Parent, but including Party C) that he considered the most promising candidates from a strategic fit perspective. He noted that Party C had reached out to reengage in exploring a potential strategic transaction and was already having preliminary discussions with the Company, and that another party on the list had already declined the opportunity (based on outreach by Mr. Shanmugaraj to a director of the Company who was affiliated with such party to determine whether such director, who had previously been excluded from all discussions of the board of directors of a potential transaction, should continue to be excluded from discussions of a potential transaction). Mr. Shanmugaraj then noted that two other parties on the list did not have a presence in the coherent optical market and lacked the financial capacity to make a competitiveall-cash offer. He further noted that pursuing anon-cash transaction with these two parties was not attractive given his view of their prospects and the risk that the delay associated with exploringnon-cash consideration could jeopardize a potential transaction with Parent. He then stated that the fifth party on the list either had, or had the ability to develop, its own internal coherent optical technologies and, in any event, was unlikely to come up to speed on the Company’s technology, customers and markets quickly. Consequently, Mr. Shanmugaraj recommended continuing discussions with Parent and Party C without additional outreach at that time. The board of directors then discussed next steps for engaging with Parent and Party C. The board of directors instructed Mr. Shanmugaraj to respond to Parent with a counter-proposal of $72 per share in anall-cash transaction, and to advise Parent that the Company would be willing to proceed with formal due diligence at that price. The board of directors also directed Mr. Shanmugaraj to continue discussions with Party C to determine whether Party C could provide an attractive proposal. Finally, the board of directors discussed formation of a Transaction Committee to allow for flexible and timely support of management under circumstances when it might not be practical to assemble the full board of directors. The board of directors agreed that all directors would be invited to attend meetings of the Transaction Committee, and that the Transaction Committee should be formed by written consent following the meeting.

On June 11, 2019, Mr. Shanmugaraj spoke to Mr. Salvagno by telephone and informed him that the board of directors had evaluated the Company’s standalone prospects and felt the current weakness in stock price was attributable to short-term volatility that had nothing to do with the long-term prospects the Company. Mr. Shanmugaraj noted that Parent’s offer of $62 per share was just at the12-month high price with no premium and failed to capture this long-term value. Mr. Shanmugaraj stated that the Company was prepared to initiate formal due diligence and engage in further discussions to explore a potential transaction if Parent increased its offer to $72 per share. Mr. Shanmugaraj also informed Mr. Salvagno that the Company was using Goldman Sachs as its financial advisor.

On June 12, 2019, Mr. Shanmugaraj received an email from the Chief Executive Officer of Party C thanking Mr. Shanmugaraj for their recent meeting and indicating that he expected to be back to the Company with additional information late the following week.

On June 13, 2019, Mr. Salvagno called Mr. Shanmugaraj and told him that Parent was concerned about the potential negative impact on the Company of current market conditions and felt that $62 per share was a fair value. Mr. Salvagno then stated that Parent was nonetheless willing to increase its offer to $64.50 per share, noting that it had difficulty getting to this price. On June 12, 2019, the closing price for Company common stock on the Nasdaq Global Select Market was $46.90 per share.

On June 17, 2019, the board of directors held a telephonic special meeting with members of senior management and representatives of Goldman Sachs and WilmerHale present for certain portions. Mr. Shanmugaraj provided the board of directors with an update on the status of discussions with Parent and Party C, informing the board of directors that Parent had increased its offer to $64.50 per share, but that Parent expressed difficulty in getting to this price. Mr. Shanmugaraj noted that there had been ongoing communications with Party C, but that Party C had still not provided any indication of value. Representatives of Goldman Sachs then presented preliminary

40

illustrative analyses of Parent’s proposal of $64.50 per share. The representatives of Goldman Sachs also discussed the potential for Parent to further increase its offer for the Company. There followed a discussion of the possibility of Party C placing a bid for the Company given their demonstrated interest. The representatives of Goldman Sachs expressed their view that Parent and Party C presented the best combination of strategic fit and ability to provide an attractive,all-cash offer. The representatives of Goldman Sachs and Mr. Shanmugaraj then provided their respective views on the remaining prospective outreach candidates, which included Party A, noting that one had already declined to pursue the opportunity and that each of the remaining parties was significantly less likely to make a competitive proposal at that point in time due to one or more of a variety of factors, including: (i) lack of strategic fit, (ii) low probability of interest in light of strategic priorities, (iii) lack of familiarity with the Company’s technology, (iv) lack of ability to finance a competitive,all-cash offer, (v) concerns over the prospects of parties that would need to offer stock consideration and (vi) the low probability of a timely offer or attractive valuation in light of such party’s historical M&A activity. In addition, Mr. Shanmugaraj reiterated his concern that expanding the process would likely result in rumors regarding a potential sale and have a significant negative impact on the Company. Mr. Shanmugaraj also observed that the remaining parties on the list were unlikely to be able to act as quickly as Parent and Party C had each indicated they desired to move, and that any significant delay could put Parent’s proposal and any proposal received from Party C at risk. A representative of WilmerHale then reviewed the fiduciary duties of the board of directors and the application of those duties in the context of a potential sale transaction. The board of directors then asked whether senior management supported continued pursuit of a potential sale transaction with Parent at $64.50 per share. Mr. Shanmugaraj stated that the price offered by Parent reflected an appropriate valuation when compared with management’s assessment of the risks associated with standalone operations, where even if the Company executed its business plan, stockholders would be exposed to risks associated with the expected continued volatility resulting from the Company’s exposure to China—where the two largest Chinese customers by revenue accounted for approximately 27% and 39% of the Company’s revenue during fiscal year 2018 and the first fiscal quarter of 2019, respectively—under the current political and macroeconomic climate, as well as the risks to the Company’s relationship with Parent as a key customer if a transaction were not pursued, and that management thus viewed this as an attractive outcome for stockholders and supported continuing the sale process as a result. The board of directors then asked Mr. Shanmugaraj if Parent had communicated its plans for management. Mr. Shanmugaraj replied that no arrangements had been discussed, other than a general statement that management would likely have a certain degree of independence for a transitional period following the closing. After further consultation with management, the board of directors concluded that management and Goldman Sachs should propose to Parent that it increase its bid to $67 per share. The board of directors noted the importance of clarifying other key terms of Parent’s proposal, including what commitments Parent was willing to make to obtain required regulatory approvals. The board of directors directed management to inform Party C that the Company was likely to move forward with another party in the near term unless Party C acted quickly to make a more specific proposal. Finally, in light of the risks associated with further outreach and the low probability that it would result in an offer that would be competitive with Parent’s current offer, the board of directors determined not to pursue outreach to additional parties at that time.

Later on June 17, 2019, Mr. Shanmugaraj spoke to Mr. Salvagno by telephone and delivered the Company’s counter-proposal to Parent of $67 per share, noting that Parent had been prepared to offer $67 per share at the outset of discussions and that he believed he could get the board of directors to accept this original proposal. Mr. Shanmugaraj went on to note that the Company felt $67 per share was a fair value of the Company based on its long-term prospects. Mr. Salvagno agreed to follow up with feedback to Mr. Shanmugaraj within the next few days.

Also on June 17, 2019, the board of directors established the Transaction Committee, consisting of directors David Aldrich, Peter Chung, Stan Reiss and John Ritchie, by unanimous written consent.

On June 18, 2019, Mr. Shanmugaraj spoke to the Chief Executive Officer of Party C by telephone. The Chief Executive Officer of Party C stated that Party C was still interested in exploring a transaction, but noted that it still needed to complete further due diligence to validate the business case for the transaction and to complete its

41

valuation. In response to further inquiry from Mr. Shanmugaraj, the Chief Executive Officer of Party C said that Party C expected its proposal to value the Company between $2.5 and $3.0 billion, but that he could not provide more than a range at that time. Mr. Shanmugaraj responded that Party C would need to be at the high end of this range to be competitive. On June 17, 2019, the closing price for Company common stock on the Nasdaq Global Select Market was $44.79 per share.

Also on June 18, 2019, representatives of Goldman Sachs spoke by telephone with the Chief Financial Officer of Party C, who indicated that Party C had more technical diligence to do, as it did not have significant familiarity with the Company’s products. The Chief Financial Officer of Party C also stated that he hoped to have preliminary due diligence completed by the end of that week.

Also on June 18, 2019, Mr. Shanmugaraj spoke to Mr. Salvagno by telephone. Mr. Salvagno stated that Parent was willing to increase its offer to $65.50 per share and confirmed that this offer reflected an all cash transaction that would be subject only to customary closing conditions. Mr. Salvagno expressed confidence in the parties’ ability to obtain regulatory clearance, but did not provide further details. Mr. Salvagno then indicated that Parent was targeting a signing in two to three weeks. On June 17, 2019, the closing price for Company common stock on the Nasdaq Global Select Market was $44.79 per share.

On June 19, 2019, the Transaction Committee held a telephonic meeting with other members of the board of directors and senior management and representatives of WilmerHale present and representatives of Goldman Sachs present for certain portions. Mr. Shanmugaraj provided an update on his conversations with Parent and Party C, noting that Parent had increased its bid to $65.50 per share and had requested a prompt response. He also noted that Party C had suggested its bid would value the Company in the range of $2.5 billion to $3.0 billion. A representative of Goldman Sachs then described his separate conversations with representatives of Party C, expressing concern about the breadth of the range communicated by Party C. The representatives of Goldman Sachs recommended continuing to support Party C’s due diligence efforts. Goldman Sachs next provided its perspective on the $65.50 per share offer from Parent. The board of directors then discussed with its legal and financial advisors whether it was realistic to expect Parent to raise its price further absent competitive pressure, and that to continue to condition diligence meetings and information on further price increases would put Parent’s offer at risk. Upon the recommendation of management, the board of directors concluded that the Company should communicate to Parent that the Company was willing to engage in detailed due diligence and negotiations at the current price, but would need further assurance and clarity regarding Parent’s proposal to obtain regulatory approval and share the risk of not obtaining approval. The board of directors also concluded the Company should continue to support Party C’s due diligence in the hope of eliciting a more specific proposal. After the representatives of Goldman Sachs left the meeting, a representative of WilmerHale reviewed the proposed terms of a Goldman Sachs engagement letter with the Transaction Committee, along with a disclosure letter provided by Goldman Sachs, which summarized Goldman Sachs’ relationship with Parent and Party C over the last two years, including information regarding compensation for financial advisory and/or underwriting services provided by its Investment Banking Division to Parent and/or its affiliates and the presence of a director on the board of directors of Parent that is currently affiliated with the Goldman Sachs Group, Inc. as a director.

Later on June 19, 2019, Mr. Shanmugaraj spoke to Mr. Salvagno by telephone and informed him that the board of directors was willing to engage in detailed due diligence and negotiations at Parent’s offer price of $65.50 per share. Mr. Shanmugaraj impressed upon Mr. Salvagno that the most significant remaining concern of the board of directors was understanding the commitments that Parent was willing to make to mitigate the potential risks to obtain required regulatory approvals for the transaction.

On June 20, 2019, members of the Company’s management spoke by telephone with representatives of Party C at Party C’s request and provided information regarding the Company’s business in response to due diligence questions from Party C.

42

Also on June 20, 2019, Mr. Salvagno sent an email to Mr. Shanmugaraj with a list of due diligence requests. He also informed Mr. Shanmugaraj that Parent expected to deliver a draft of the merger agreement in the next day or two.

Also on June 20, 2019, a representative from Goldman Sachs received a text from the Chief Financial Officer of Party C, asking to speak over the phone on June 21, 2019, and noting that Party C would be submitting a proposal on June 21, 2019.

On June 21, 2019, counsel to Parent Fenwick & West LLP, which we refer to as Fenwick, delivered a draft merger agreement to WilmerHale. From June 21 to July 8, 2019, Fenwick and WilmerHale negotiated the terms of the definitive merger agreement, including the provisions relating to (i) the allocation of the risks associated with regulatory approvals, (ii) restrictions on the Company’s operations between signing and closing, (iii) the ability of the board of directors to respond to unsolicited acquisition proposals, change its recommendation and accept a superior proposal, (iv) the amount and triggers for the Company’s termination fee, (v) the closing conditions, (vi) the definition of a material adverse effect and (vii) the scope of the representations and warranties.

Also on June 21, 2019, a representative of Party C called a representative of Goldman Sachs and informed him that Party C expected to deliver a written indication of interest in acquiring the Company for $73 per share in cash, with no financing contingency. A representative of Party C also called Mr. Shanmugaraj and provided this same information. Later that day, Party C delivered anon-binding indicative offer letter expressing Party C’s interest in acquiring the Company at $73 per share in cash, subject to the satisfactory completion of due diligence, negotiation of a mutually acceptable merger agreement and final approval of Party C’s board of directors. The letter indicated that the completion of the transaction would not be subject to any financing contingency. The letter indicated that Party C expected that a definitive agreement for such a transaction could be signed by the week of July 8, 2019. On June 20, 2019, the closing price for Company common stock on the Nasdaq Global Select Market was $47.38 per share.

On June 22, 2019, the Transaction Committee held a telephonic meeting with other members of the board of directors and senior management and representatives of WilmerHale present and representatives of Goldman Sachs present for certain portions. Mr. Shanmugaraj and a representative of Goldman Sachs reviewed the terms of thenon-binding indicative offer letter received from Party C and provided their perspective on the risks associated with Party C’s proposal, noting that Party C’s internal process and due diligence efforts were considerably behind those of Parent. The Transaction Committee instructed management to continue exploring a potential transaction with Party C in parallel with its discussions with Parent, including facilitating formal due diligence. The Transaction Committee also authorized management to finalize the terms of and execute an engagement letter with Goldman Sachs on terms consistent with those discussed at the prior meeting, with such changes as deemed appropriate by management.

On June 23, 2019, Mr. Salvagno called Mr. Shanmugaraj and told him that Parent was requesting exclusivity, which it felt was appropriate given the progress to date. Later that day, Mr. Salvagno sent Mr. Shanmugaraj a draft exclusivity agreement, which provided for a30-day period of exclusivity. Mr. Shanmugaraj responded that he would have to take the matter to the board of directors for further discussion.

On June 24, 2019, the Company provided access to an electronic data room to Parent and Party C to facilitate their due diligence. The June LRP was made available to Parent on June 25, 2019, when it was posted to the electronic data room. Between June 26, 2019 and July 6, 2019, the Company conducted numerous due diligence meetings and teleconferences with both Parent and Party C, includingin-person due diligence meetings with Party C on June 26—27, 2019, and with Parent on June 27—29, 2019, in each case at the offices of WilmerHale in Boston.

Also on June 24, 2019, representatives of Goldman Sachs spoke by telephone with Mr. Salvagno and informed him that the Company had received an inbound expression of interest from a third party that was continuing to

43

evaluate the Company, and that the Company could not agree to exclusivity under those circumstances. The representatives of Goldman Sacks noted that the third party had expressed interest at a higher price, but was earlier in its evaluation of the Company, and that the Company would continue to support Parent’s due diligence efforts.

Also on June 24, 2019, Mr. Salvagno spoke by telephone with Mr. Shanmugaraj, who confirmed the receipt of an inbound expression of interest at a higher price and that the Company would continue to support Parent’s due diligence efforts.

On June 25, 2019, the Company executed an engagement letter with Goldman Sachs to serve as the Company’s financial advisor in connection with a potential transaction. Additionally, certain members of senior management of Party C met with Mr. Shanmugaraj and selected members of the Company’s management for dinner in Boston prior to Party C’sin-person diligence meetings on June 26—27, 2019, as noted above.

On June 25 and 26, 2019, the Company entered into Clean Team Confidentiality Agreements with each of Parent and Party C, respectively, providing for additional access and disclosure restrictions on certain competitively sensitive information.

On June 28, 2019, Mr. Shanmugaraj spoke to representatives of Party C by telephone to discuss certain process and timing matters. The representative of Party C indicated that Party C’s counsel was starting on a draft merger agreement, to which Mr. Shanmugaraj replied that the Company was already preparing to send a draft merger agreement to Party C in the next 24 – 48 hours.

Later on June 28, 2019, Mr. Shanmugaraj and selected members of the Company management met with selected members of Parent management for dinner in Boston on the second day of thein-person diligence meetings on June 27—29, 2019, as noted above.

On June 29, 2019, WilmerHale delivered a draft merger agreement to counsel to Party C. Despite repeated requests for comments on the draft merger agreement, none were ever provided by or on behalf of Party C.

On June 30, 2019, Mr. Shanmugaraj spoke to a representative of Party C by telephone and to confirm Party C’s anticipated timeline for signing a definitive agreement as outlined in its June 21, 2019 proposal. The representative of Party C suggested that Mr. Shanmugaraj meet with the Chief Executive Officer of Party C to further discuss plans for proceeding to a definitive agreement.

On July 1, 2019, representatives of Goldman Sachs spoke by telephone with representatives of Parent to confirm Parent’s anticipated timeline for executing a definitive agreement. The representatives of Parent indicated that they were anticipating approval from Parent’s board of directors on July 8, 2019, with signing occurring by July 10, 2019, but as early as July 9, 2019.

Also on July 1, 2019, Mr. Shanmugaraj received a text message from the Chief Executive Officer of Party A, indicating that he had heard “rumors” and expressed interest in connecting to discuss a potential strategic transaction with Party A. After consulting with representatives of Goldman Sachs and WilmerHale, Mr. Shanmugaraj replied by text to the Chief Executive Officer of Party A on July 2, 2019 and suggested a meeting during the week of July 8, 2019.

On July 2, 2019, Mr. Shanmugaraj spoke with a representative of Party C by telephone. The representative communicated that Party C was working towards a timeline that would result in the signing of a merger agreement with the Company on July 9, 2019.

Also on July 2, 2019, a representative of Parent sent to the Company initial drafts of proposed employment arrangements for Mr. Shanmugaraj, Mr. Mikkelsen, Mr. Givehchi, and Christian Rasmussen, Founder and Vice President of Digital Signal Processing and Optics of the Company.

On July 3, 2019, Mr. Shanmugaraj and other members of the Company’s senior management met with the Chief Executive Officer of Party C over lunch near Party C’s headquarters. The Chief Executive Officer of Party C indicated that he and other members of senior management were still evaluating the transaction, and given that such a transaction would involve a new business model, would need at least an additional two weeks to finalize its evaluation of, and determine its willingness to proceed with, a transaction. Mr. Shanmugaraj asked if this was just a situation of needing more time to complete confirmatory due diligence, or if more evaluation of the merits and risks of the transaction, due to the nature of the Company’s business model, had to be performed, to which the Chief Executive Officer of Party C responded that additional analysis of the business model and the merits of the transaction needed to be performed. Mr. Shanmugaraj informed the Chief Executive Officer of Party C that the other party was moving very quickly and that a definitive agreement might be signed with the other party the week of July 8, 2019. Mr. Shanmugaraj asked the Chief Executive Officer of Party C if he was willing to risk loss of the transaction through the delay, to which the Chief Executive Officer of Party C responded that he understood the risk and was willing to take it.

On July 3, 2019, a representative of Parent sent a detailed plan to Goldman Sachs outlining steps to a sign a definitive agreement on July 8, 2019.

On July 4, 2019, representatives of Goldman Sachs spoke by telephone to the Chief Financial Officer of Party C, who conveyed that Party C was still evaluating the business case for a potential transaction with the Company and would need at least two more weeks to reach a decision on whether it would proceed with any transaction. The representatives of Goldman Sachs reminded the Chief Financial Officer of Party C that the Company was engaged in discussions with another interested party, and the Chief Financial Officer of Party C acknowledged the risk that the Company could move forward with another transaction within this timeframe.

On July 5, 2019, Mr. Shanmugaraj received a text message from a representative of Party C expressing Party C’s continued interest in pursuing a transaction.

Also on July 5, 2019, the Transaction Committee held a telephonic meeting with other members of the board of directors and senior management and representatives of WilmerHale present and representatives of Goldman Sachs present for certain portions. Mr. Shanmugaraj provided an update on the status of discussions and due diligence with Parent and Party C. Mr. Shanmugaraj noted that Parent was highly engaged and progressing rapidly, whereas Party C was less engaged and falling further behind Parent. Mr. Shanmugaraj noted that Parent had internal management support to pursue the transaction, whereas Party C had communicated that its senior management was still evaluating the merits of the potential transaction and needed more time to make a final determination. Mr. Shanmugaraj then described the text message he had received from the Chief Executive Officer of Party A and his response. A representative of Goldman Sachs next described a conversation between the representative of Goldman Sachs and the Chief Financial Officer of Party C. The representative of Goldman Sachs stated that, in view of Party C’s admission that it was still working to validate the business case for a transaction, the lack of any response to the draft merger agreement, and the additional time required before Party C would finalize its evaluation of the Company’s business model and determine its willingness to proceed with a transaction, there was risk that Party C might not move forward with any transaction with the Company within a reasonable timeframe. Representatives of WilmerHale next provided an update regarding the negotiation of the merger agreement with Parent, discussing in particular the proposed allocation of the risks associated with regulatory approvals, including terms of an addendum to the existing Master Purchase Agreements with Parent providing for additional purchase commitments by Parent, agreed upon commitments to achieve regulatory approvals and special interim operating covenants that would permit the Company greater flexibility to enter into new, or amendments to existing, supply agreements with customers, and Parent’s commitment to affirm such agreements. Representatives of Goldman Sachs provided an overview of prior discussions with Party A regarding a potential strategic transaction. Representatives of Goldman Sachs then presented an illustrative analysis of a combination with Party A, noting in particular that it would be very difficult for Party A to complete anall-cash transaction at the prices under discussion with Parent and Party C, given Party A’s available cash and the implied leverage required to finance such a transaction, and that a mixed cash and stock transaction would be highly

45

dilutive to Party A’s earnings per share. As a result, representatives of Goldman Sachs expressed skepticism that Party A would be in a position to make a competitive offer. The representatives of Goldman Sachs also noted that any mixed cash and stock transaction with Party A would likely require approval by Party A’s stockholders, which would increase the execution risk of pursuing such a transaction. A representative of WilmerHale then reviewed the fiduciary duties of the board of directors. The Transaction Committee then discussed next steps with the various parties. The representatives of Goldman Sachs expressed concern that Parent might terminate discussions if the Company attempted to delay negotiations in an effort to provide the additional two weeks requested by Party C. Mr. Gavin also noted that there had been very little engagement by Party C or its advisors on due diligence over the last few days, which supported heightened concern that Party C was not committed to a transaction. The Transaction Committee concluded that management and Goldman Sachs should indicate to Parent that the Company had a superior cash offer, but was willing to move forward quickly with Parent if it significantly increased its price to a number “in the $70s” and agreed to a satisfactory resolution of regulatory matters, including a reverse termination fee for failure to close due to failure to obtain regulatory approvals, while continuing to pursue engagement with Party C. The Transaction Committee also decided not to pursue further discussions with Party A at that time.

On July 5, 2019, Mr. Shanmugaraj had a telephone call with Mr. Salvagno and informed him that, because the Company had received a higher offer from another party, Parent would have to increase its offer to a number “in the $70s.” In addition, Mr. Shanmugaraj stated that the board of directors would require a reverse termination fee for failure to close due to the failure to obtain regulatory approvals in order to proceed with signing a definitive agreement. Mr. Salvagno replied that he would discuss the matter internally and work to get back with a response quickly.

On July 6, 2019, Mr. Goeckeler called Mr. Shanmugaraj to discuss the message conveyed to Mr. Salvagno. Mr. Shanmugaraj reiterated that, since the Company had a higher offer from another party, Parent had to increase its offer to a number “in the $70s.” Mr. Shanmugaraj also repeated that the board of directors would require a reverse termination fee for failure to close due to the failure to obtain regulatory approvals in order to proceed with signing a definitive agreement. Mr. Goeckeler indicated that he would work internally to come back with an acceptable proposal.

Later on July 6, 2019, Mr. Shanmurgaraj spoke with Mr. Salvagno by telephone. Mr Salvagno informed Mr. Shanmurgaraj that Parent’s board of directors of Directors had approved an offer of $68 per share for the Company. Mr Shanmugaraj responded that the value gap between this offer and the competing offer was still too wide, and that an acceptable offer would also need to include a reverse termination fee, as previously discussed. Later that day, Mr. Salvagno called Mr. Shanmugaraj to indicate that Parent was prepared to increase its proposed price to $70 per share and to pay a reverse termination fee equal to approximately 4% of equity value for failure to close due to the failure to obtain regulatory approvals;provided that the Company agreed to an equivalent amount for its termination fee. He also indicated that this was Parent’s best and final offer, and that Parent needed a response to such offer within 24 hours. Following this call, the Company received a revised written proposal from Mr. Salvagno that Parent was prepared to increase its proposed price to $70 per share and to pay a reverse termination fee equal to approximately 4% of equity value for failure to close due to specified regulatory matters;provided that the Company agreed to an equivalent amount for its termination fee. The proposal indicated that it was Parent’s best and final offer, and was contingent on the Company executing a definitive agreement on July 8, 2019. On July 5, 2019, the closing price for Company common stock on the Nasdaq Global Select Market was $48.14 per share.

On July 7, 2019, the Transaction Committee held a telephonic meeting with other members of the board of directors and senior management and representatives of WilmerHale present and representatives of Goldman Sachs present for certain portions. Mr. Shanmugaraj summarized the discussions with Parent and Party C since the last meeting and the terms of the updated proposal from Parent at $70 per share, noting that the proposal was contingent on executing a definitive agreement on July 8, 2019. Mr. Shanmugaraj and a representative of WilmerHale summarized the agreements reached with Parent regarding commitments to mitigate regulatory risk,

46

including the reverse termination fee in the latest Parent proposal. Representatives of Goldman Sachs and the Transaction Committee also discussed the proposed size of the Company’s termination fee, as well as termination fees in precedent transactions distributed in advance of the meeting. The representatives of Goldman Sachs next presented preliminary illustrative analyses of Parent’s latest offer. A representative of Goldman Sachs recommended one more final outreach to Party C to confirm that no formal offer was forthcoming and to advise them that the Company was prepared to move forward promptly with an alternative transaction if that were not the case. Mr. Shanmugaraj then provided an overview of the employment andnon-compete arrangements proposed by Parent for certain members of senior management, including himself and Benny Mikkelsen, who was also a member of the board of directors, and it was agreed that a summary of these arrangements would be provided to the board of directors in advance of its next meeting. A representative of WilmerHale then reviewed the fiduciary duties of the board of directors and the application of those duties to the decision of whether to proceed with a transaction with Parent. At the request of the Transaction Committee, each member of management present confirmed his or her view that a transaction with Parent at $70 per share was superior to the prospects of remaining an independent standalone entity. The Transaction Committee instructed Goldman Sachs and management to contact Party C prior to the next board of directors meeting and, absent a definitive commitment from Party C to move forward promptly at a higher price, to finalize the terms of a transaction with Parent.

On July 7, 2019, Mr. Shanmugaraj spoke to Mr. Salvagno by telephone and conveyed that the board of directors was prepared to proceed based on the latest proposal from Parent. Mr. Shanmugaraj also spoke by telephone with Mr. Goeckeler the same day to convey the board of directors’s support for the proposed transaction.

On July 8, 2019, a representative of Goldman Sachs spoke to the Chief Financial Officer of Party C and inquired if Party C’s perspective or timetable had changed and was informed that it had not. The representative of Goldman Sachs indicated to the Chief Financial Officer of Party C that given the risk associated with Party C and the available alternative, the Company would likely move forward with an alternative transaction. Following this discussion, at the direction of the Company, representatives from Goldman Sachs terminated Party C’s access to the electronic data room.

Later on July 8, 2019, the board of directors held a telephonic meeting, with members of senior management and representatives of Goldman Sachs and WilmerHale present. The representatives of Goldman Sachs reported on its outreach to Party C and the lack of any change in Party C’s position. Representatives of WilmerHale reviewed the fiduciary duties of the board of directors in connection with their consideration and approval of the merger agreement and presented a summary of the principal terms of the definitive merger agreement between Parent and the Company previously distributed to the directors. Representatives of Goldman Sachs reviewed financial analyses of the $70 in cash per share of Company common stock to be paid by Parent pursuant to the merger agreement. Representatives of Goldman Sachs then rendered to the board of directors its oral opinion, subsequently confirmed in writing, to the effect that, as of July 8, 2019, and based upon and subject to the factors and assumptions set forth therein, the $70.00 per share merger consideration to be paid to the holders (other than Parent or any affiliate of Parent) of Company common stock was fair from a financial point of view to such holders. (See “TheMerger—Opinions of the Company’s Financial Advisors.”) After discussion, the board of directors unanimously voted to approve the merger agreement and the transactions contemplated thereby, including the merger, to recommend the merger agreement to the Company’s stockholders and to adopt a forum selectionby-law amendment.

Following the board of directors meeting, the Company and Parent executed and delivered the merger agreement and issued a joint press release on July 9, 2019 announcing the transaction.

Reasons for the Merger; Recommendation of the Board of Directors

At a meeting held on July 8, 2019, the board of directors, by a unanimous vote of all of its directors, (a) determined and declared that the merger agreement, the merger and the other transactions contemplated by the merger agreement, on the terms and subject to the conditions set forth therein, are advisable, fair to and in the

47

best interests of the Company and its stockholders, (b) adopted and approved the merger agreement, the merger and the other transactions contemplated by the merger agreement and (c) determined that it is advisable and in the best interests of the Company for the board of directors to submit the merger agreement to the Company’s stockholders for adoption and directed that the merger agreement be submitted to the Company’s stockholders at a special meeting of the Company’s stockholders for their adoption, and recommended that the Company’s stockholders adopt the merger agreement.

Before making its recommendation, the board of directors consulted with its outside legal and financial advisors and with the Company’s senior management team. In reaching its recommendation, the board of directors considered the following material factors that it believes support its decision to enter into the merger agreement and consummate the merger (which factors are not necessarily presented in order of relative importance):

• Best Alternative for Maximizing Stockholder Value. The board of directors believed that receipt of the merger consideration of $70.00 per share in cash was more favorable to the Company stockholders than the likely value that would result from other potential transactions or remaining independent. This decision was based on, among other things, the board of directors’ assessment of:

^○  the Company’s historical operating and financial performance;

^○  the Company’s competitive position, including potential competition from larger companies and concerns that Parent, the Company’s second largest customer by revenue, accounting for approximately 14% and 18.1% of the Company’s revenue during fiscal year 2018 and the first quarter of 2019, respectively, might acquire one of the Company’s competitors, shift its purchasing to a second source or develop competitive technology internally if it were unable to acquire the Company, with the resulting loss in revenue and potentially increased competitive risk;

^○  the Company’s future prospects on a standalone basis, including continued risks related to the Company’s exposure to China—where the Company’s two largest Chinese customers by revenue accounted for approximately 27% and 39% of the Company’s revenue during fiscal year 2018 and the first fiscal quarter of 2019, respectively— under the current political and macroeconomic climate, as well as the resulting volatility in the Company’s stock price;

^○  the advantages of entering into the merger agreement in comparison with the risks of remaining independent, including risks related to executing the Company’s business plan and achieving the Company’s financial projections as a standalone company; the risks inherent in the Company’s industry, including historical volatility inend-customer demand for optical technologies; risks associated with the development and market acceptance of its products under development and the continued operating expenses to sustain the product roadmap; the risk of increased competitive pressure; the economy and capital markets as a whole; and the various additional risks and uncertainties that are described in the Company’s most recent annual report on Form10-K filed with the SEC or subsequently filed quarterly reports on Form10-Q;

^○  the board of directors’ belief that its negotiations had resulted in the highest price per share for the Company common stock that Parent was willing to pay; and

^○  the board of directors’ belief that its evaluation of potentially interested parties and the process conducted by the Company had resulted in the highest price reasonably available to the stockholders of the Company.

48

• Attractive Value. The board of directors concluded that the consideration of $70.00 per share represented an attractive valuation for the Company and an opportunity for the Company’s stockholders to receive a significant premium over the market price of the Company common stock. The board of directors reviewed the historical market prices, volatility and trading information with respect to the Company common stock, and the sale process undertaken by the Company, including:

^○  the fact that the proposed consideration of $70.00 per share represents a premium of (i) 45.4% compared to the closing price of the Company common stock of $48.14 per share on July 5, 2019, the last trading date prior to the date of the board of directors meeting, (ii) 47.9% compared to $47.32, the volume weighted average price of the Company common stock for the30-day period ended July 5, 2019, (iii) 37.0% compared to $51.09, the volume weighted average price of the Company common stock for the90-day period ended July 5, 2019, (iv) 36.6% compared to $51.25, the volume weighted average price of the Company common stock for the180-day period ended July 5, 2019, (v) 52.1% compared to $46.03, the volume weighted average price of the Company common stock for theone-year period ended July 5, 2019, (vi) 14.7% compared to $61.04, the highest closing price per share of the Company common stock for the52-week period ended July 5, 2019 and (vii) 120.3% compared to $31.78, the lowest closing price per share of the Company common stock for the52-week period ended July 5, 2019;

^○  the unlikelihood of an executable transaction at a higher value than the cash price to be paid by Parent, in light of (i) Party C’s unwillingness to negotiate a definitive agreement or commit to a specific timeline to execute a definitive agreement, (ii) the lack of conviction of Party C’s senior management in discussions regarding a strategic transaction, including prior discussions in 2018, (iii) management and Goldman Sachs’ assessment of potential candidates for further outreach and their ability to transact on competitive terms and (iv) the fact that the Company actively solicited increases in the offer made by Parent and Parent indicated that the merger consideration was its best and final offer; and

^○  the risk that prolonging or expanding the sale process further could have (i) resulted in the loss of an opportunity to consummate a transaction with Parent, (ii) increased the risk of leaks regarding the discussions with Parent or Party C, which could have negatively impacted the Company’s business and its relationships with customers and suppliers and (iii) distracted senior management from implementing the Company’s business plan.

• Greater Certainty of Value. The proposed consideration consists solely of cash, which provides immediate liquidity and certainty of value to the Company’s stockholders. The receipt of cash consideration also eliminates for the Company’s stockholders the risk of the continued execution of the Company’s business on a standalone basis.

• Likelihood of Completion. The likelihood that the merger will be consummated, particularly in view of the terms of the merger agreement and the closing conditions. In that regard, the board of directors noted:

^○  that the merger is not subject to any financing-related condition;

^○  the size and financial strength of Parent, and Parent’s ability to fund the merger consideration with cash;

^○  the limited number of conditions to the merger;

^○  the fact that the addendum to the Master Purchase Agreements with Parent provides that, in the event the merger agreement is terminated under certain circumstances, Parent will pay the Company a $120,000,000 special payment, without the Company having to establish any damages;

^○  the remedy of specific performance available to the Company under the merger agreement in the event of breaches by Parent; and

49

^○  Parent’s obligation to undertake certain specified remedies to obtain antitrust clearance.

• Business Reputation of Parent. The board of directors considered Parent’s business reputation, management, financial resources and extensive history of successfully consummating transactions, as well as the existing positive commercial relationship between the Company and Parent, as the Company’s second largest customer by revenue in the first quarter of 2019. The board of directors believed these factors supported the conclusion that a transaction with Parent could be completed in a timely and orderly manner.

• Relationships with Financial Advisor. The determination of the board of directors that the relationships between Goldman Sachs, on the one hand, and each of the Company, Parent and Party C, on the other hand, would not impair the ability of Goldman Sachs to provide impartial advice to the board of directors and the fact that Goldman Sachs agreed at the outset of its engagement with the Company that it would not finance an acquisition of the Company without the Company’s consent.

• Receipt of Opinion from Goldman Sachs. The financial analyses presented to the board of directors by Goldman Sachs, as well as the opinion of Goldman Sachs, dated July 8, 2019, to the effect that, as of the date of such opinion, and based upon and subject to the factors and assumptions set forth therein, the $70.00 per share merger consideration to be paid to the holders (other than Parent or any affiliate of Parent) of Company common stock is fair from a financial point of view to such holders, as more fully described below in “The Merger — Opinions of the Company’s Financial Advisors” beginning on page [—] and the full text of such opinion is attached to this proxy statement as Annex [—].

• Terms of Merger Agreement. The terms and conditions of the merger agreement, including the Company’s ability to consider and respond to, under certain circumstances specified in the merger agreement, an unsolicited written acquisition proposal (as more fully described under the heading “The Merger Agreement —Restrictions on Solicitation of Other Offers”), and the board of directors’ right, after complying with the terms of the Merger Agreement, to terminate the merger agreement in order to enter into an agreement with respect to a superior proposal (as more fully described under the heading “The Merger Agreement —Restrictions on Changes of Recommendation to Company Stockholders”), subject to certain match rights in favor of Parent and upon payment of a termination fee to Parent of $120,000,000, which is approximately 3.9% of the equity value of the Company, as described under “The Merger Agreement — Termination Fee” beginning on page [—].

• Required Stockholder Approval. The merger agreement is subject to adoption by the Company’s stockholders, who are free to reject the merger agreement.

• Appraisal Rights. The board of directors considered the fact that stockholders who properly exercise and perfect their appraisal rights under Delaware law will be entitled to such appraisal rights in connection with the merger.

The board of directors also weighed the factors described above against the following factors and risks that generally weighed against entering into the merger agreement (which factors and risks are not necessarily presented in order of relative importance):

• No Stockholder Participation in Future Growth or Earnings. The Company will no longer exist as an independent company, and accordingly, Company stockholders will no longer participate in any future growth the Company may have or any potential future increase in its value.

• Effect of Failure to Complete Transactions. While the Company expects that the merger will be consummated, there can be no assurance that all conditions to the parties’ obligations to complete the merger will be satisfied, and thus it is possible that the merger may not be completed in a timely manner or at all. If the merger is not completed, (i) the Company will have incurred significant risk and transaction and opportunity costs, including the possibility of disruption to the Company’s operations, diversion of management and employee attention, employee attrition and a potentially negative effect on the Company’s business and customer and supplier relationships, (ii) the trading price of shares of

50

Company common stock would likely be adversely affected and (iii) the market’s perceptions of the Company’s prospects could be adversely affected.

• Closing Conditions. The fact that completion of the merger would require antitrust clearance in the United States, Austria, Germany and the People’s Republic of China and the satisfaction of certain other closing conditions, including that no Company material adverse effect has occurred, which conditions are not entirely within the Company’s control and that there can be no assurances that any or all such conditions will be satisfied.

• Interim Restrictions on Business. The Company’s management’s focus and resources may become diverted from other important business opportunities and operational matters while working to implement the merger, and the merger agreement imposes restrictions on the conduct of the Company’s business prior to the effective time of the merger, which could adversely affect the Company’s business.

• Risk of Litigation. There is a risk of litigation arising in respect of the merger agreement or the transactions contemplated by the merger agreement.

• Taxable Consideration. The merger will be a taxable transaction to the Company’s stockholders that are U.S. holders (as defined under the heading “—U.S. Federal Income Tax Consequences of the Merger” below) for U.S. federal income tax purposes and, therefore, such stockholder generally will be required to pay U.S. federal income tax on any gains they recognize as a result of the merger.

• No Solicitation. The terms of the merger agreement prohibit the Company and its representatives from soliciting third-party bids, including soliciting additional proposals from Party C, and Parent has the right to match an unsolicited third-party bid if made, which terms could reduce the likelihood that other potential acquirers would propose an alternative transaction that may be more advantageous to the Company’s stockholders.

• Termination Fee. The possibility that if the merger is not consummated, subject to certain limited exceptions, the Company will be required to pay its own expenses associated with the merger agreement and the transactions contemplated thereby and, under certain circumstances, to pay Parent a termination fee of $120,000,000 in connection with the termination of the merger agreement.

In considering the recommendation of the board of directors with respect to the proposal to adopt the merger agreement, you should be aware that the Company’s directors and executive officers may have interests in the merger that are different from, or in addition to, yours. The board of directors was aware of and considered these interests, among other matters, in evaluating and negotiating the merger agreement and the merger, and in their recommendations with respect to the merger agreement. See the section entitled “The Merger — Interests of Certain Persons in the Merger” beginning on page [—].

The foregoing discussion of the information and factors considered by the board of directors in reaching its conclusions and recommendations is not intended to be exhaustive, but includes the material factors considered by the directors. In view of the wide variety of factors considered in connection with its evaluation of the merger and the complexity of these matters, the board of directors did not find it practicable to, and did not attempt, to quantify, rank or assign any relative or specific weights to the various factors considered in reaching its determination and making its recommendation. In addition, individual directors may have given different weights to different factors. The board of directors considered all of the foregoing factors as a whole and based its recommendation on the totality of the information presented.

51

The board of directors recommends that you vote “FOR” approval of the proposal to adopt the merger agreement, “FOR” approval of the nonbinding advisory proposal regarding compensation that may be payable to our named executive officers in connection with the merger and “FOR” approval of the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies.

Opinion of the Company’s Financial Advisor

Goldman Sachs rendered its opinion to the board of directors that, as of July 8, 2019 and based upon and subject to the factors and assumptions set forth therein, the $70.00 in cash per share to be paid to the holders (other than Parent and its affiliates) of shares of Company common stock pursuant to the Merger Agreement was fair from a financial point of view to such holders.

The full text of the written opinion of Goldman Sachs, dated July 8, 2019, which sets forth assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with the opinion, is attached asAnnex B. Goldman Sachs provided advisory services and its opinion for the information and assistance of the board of directors in connection with its consideration of the merger. The Goldman Sachs opinion is not a recommendation as to how any holder of Company common stock should vote with respect to the merger, or any other matter.

In connection with rendering the opinion described above and performing its related financial analyses, Goldman Sachs reviewed, among other things:

• the merger agreement;

• Annual Reports to stockholders and Annual Reports on Form10-K of the Company for the three years ended December 31, 2018;

• the Company’s Registration Statement on FormS-1, including the prospectus contained therein dated May 13, 2016, relating to an initial public offering of Company common stock;

• certain interim reports to stockholders and Quarterly Reports on Form10-Q of the Company;

• certain other communications from the Company to its stockholders;

• certain publicly available research analyst reports for the Company; and

• certain internal financial analyses and forecasts for the Company prepared by its management, as approved for Goldman Sachs’ use by the Company, which are referred to as the “Forecasts”.

Goldman Sachs also held discussions with members of the senior management of the Company regarding their assessment of the past and current business operations, financial condition, and future prospects of the Company; reviewed the reported price and trading activity for the Company common stock; compared certain financial and stock market information for the Company with similar information for certain other companies the securities of which are publicly traded; reviewed the financial terms of certain recent business combinations in the communication technology and semiconductor industries and in other industries; and performed such other studies and analyses, and considered such other factors, as it deemed appropriate.

For purposes of rendering its opinion, Goldman Sachs, with the Company’s consent, relied upon and assumed the accuracy and completeness of all of the financial, legal, regulatory, tax, accounting and other information provided to, discussed with or reviewed by, it, without assuming any responsibility for independent verification thereof. In that regard, Goldman Sachs assumed with the Company’s consent that the Forecasts were reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of the Company. Goldman Sachs did not make an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or otheroff-balance-sheet assets and liabilities) of the Company or any of its subsidiaries and it was not furnished with any such evaluation or appraisal. Goldman Sachs assumed that all

52

governmental, regulatory or other consents and approvals necessary for the consummation of the merger will be obtained without any adverse effect on the expected benefits of the merger in any way meaningful to its analysis. Goldman Sachs has also assumed that the merger will be consummated on the terms set forth in the merger agreement, without the waiver or modification of any term or condition the effect of which would be in any way meaningful to its analysis.

Goldman Sachs’ opinion does not address the underlying business decision of the Company to engage in the transaction or the relative merits of the transaction as compared to any strategic alternatives that may be available to the Company; including an expression of interest for a transaction proposed by a third party that may have resulted in a higher price per share in cash than in the merger, which the Company advised Goldman Sachs, the Company determined not to further pursue because of risks and uncertainties concerning such potential transaction, nor does it address any legal, regulatory, tax or accounting matters. Goldman Sachs’ opinion addresses only the fairness from a financial point of view, to the holders (other than Parent and its affiliates) of shares of Company common stock, as of the date of Goldman Sachs’ opinion, of the $70.00 in cash per share to be paid to such holders pursuant to the merger agreement. Goldman Sachs’ opinion does not express any view on, and does not address, any other term or aspect of the merger agreement or the merger or any term or aspect of any other agreement or instrument contemplated by the merger agreement or entered into or amended in connection with the merger, including the fairness of the merger to, or any consideration received in connection therewith by, the holders of any other class of securities, creditors, or other constituencies of the Company; nor as to the fairness of the amount or nature of any compensation to be paid or payable to any of the officers, directors or employees of the Company, or class of such persons, in connection with the merger, whether relative to the $70.00 in cash per share to be paid to the holders (other than Parent and its affiliates) of shares of Company common stock pursuant to the merger agreement or otherwise. Goldman Sachs did not express any opinion as to the impact of the merger on the solvency or viability of the Company or Parent or the ability of the Company or Parent to pay their respective obligations when they come due. Goldman Sachs’ opinion was necessarily based on economic, monetary market and other conditions, as in effect on, and the information made available to it as of the date of the opinion and Goldman Sachs assumed no responsibility for updating, revising or reaffirming its opinion based on circumstances, developments or events occurring after the date of its opinion. Goldman Sachs’ opinion was approved by a fairness committee of Goldman Sachs.

The following is a summary of the material financial analyses delivered by Goldman Sachs to the board of directors in connection with rendering the opinion described above. The following summary, however, does not purport to be a complete description of the financial analyses performed by Goldman Sachs, nor does the order of analyses described represent relative importance or weight given to those analyses by Goldman Sachs. Some of the summaries of the financial analyses include information presented in tabular format. The tables must be read together with the full text of each summary and are alone not a complete description of Goldman Sachs’ financial analyses. Except as otherwise noted, the following quantitative information, to the extent that it is based on market data, is based on market data as it existed on or before July 5, 2019, the last completed trading day before the date of Goldman Sachs’ opinion, and is not necessarily indicative of current market conditions.

Historical Stock Trading Analysis

Goldman Sachs reviewed the historical trading prices and volumes for the Company common stock for the52-week period ended July 5, 2019 the last completed trading day before the date of Goldman Sachs’ opinion. In addition, Goldman Sachs analyzed the $70.00 in cash per share of the Company’s common stock to be paid to the holders of the Company’s common stock pursuant to the merger agreement in relation to (i) the highest closing price per share of Company common stock for the52-week period ended July 5, 2019; and (ii) the lowest closing price per share of Company common stock for the52-week period ended July 5, 2019.

53

This analysis indicated that the price per share to be paid to the holders of the Company’s common stock pursuant to the merger agreement represented:

• a premium of 14.7% to the highest closing trading price per share of Company common stock of $61.04 for the52- week period ended July 5, 2019; and

• a premium of 120.3% to the lowest closing trading price per share of Company common stock of $31.78 for the52- week period ended July 5, 2019.

Selected Companies Analysis

Goldman Sachs reviewed and compared certain financial information for the Company to corresponding financial information, ratios and public market multiples for the following publicly traded corporations in the optical and semiconductor industries, which we refer to as the selected companies:

Optical Industry

• ADVA Optical Networking SE

• Applied Optoelectronics, Inc.

• Ciena Corporation

• II-VI Incorporated

• Lumentum Holdings Inc.

Semiconductor Industry

• MACOM Technology Solutions Holdings, Inc.

• Inphi Corporation

• IPG Photonics Corporation

• Mellanox Technologies, Ltd.

• Semtech Corporation

• Marvell Technology Group Ltd.

• MaxLiner, Inc.

Although none of the selected companies is directly comparable to the Company, the companies included were chosen because they are publicly traded companies with operations that for purposes of analysis may be considered similar to certain operations of the Company.

Goldman Sachs calculated and compared various financial multiples and ratios for the Company and the selected companies based on financial and trading data as of July 5, 2019, information it obtained from SEC filings, the Institutional Brokers’ Estimate System consensus estimates, and, for the Company, also the Forecasts. With respect to the Company and the selected companies, Goldman Sachs calculated the average multiples of such company’s estimated future earnings before interest, tax depreciation and amortization (which we refer to as “EBITDA”) and its assumed next12-month enterprise value to EBITDA multiple (which we refer to as “NTM EV/EBITDA”) over certain time periods ending July 5, 2019. The results of these analyses are summarized as follows:

Average NTM EV/ EBITDA Multiples	One Month		Three Months		Six Months		One year		2 years
Company		17.0x		20.1x		20.6x		20.6x		17.6x
Optical Peers		9.2x		8.9x		8.4x		8.0x		8.0x
Semiconductor Peers		15.8x		15.2x		14.2x		13.2x		12.9x

54

Goldman Sachs also calculated the average multiples of such company’s estimated future earnings per share (which we refer to as “EPS”) and its assumed next12-month price to future earnings per share multiple (which we refer to as “NTM P/E”) over certain time periods ending July 5, 2019 for the Company and the selected companies. The results of these analyses are summarized as follows:

Average NTM EV/ EBITDA Multiples	One Month		Three Months		Six Months		One year		2 years
Company		25.7x		30.1x		31.8x		34.1x		28.6x
Optical Peers		14.1x		14.6x		14.3x		15.3x		15.3x
Semiconductor Peers		22.6x		22.6x		20.9x		19.1x		18.7x

Illustrative Present Value of Future Share Price Analysis

Goldman Sachs performed an illustrative analysis of the implied present value of the future value per share of Company common stock, which is designed to provide an indication of the present value of a theoretical future value of a company’s equity as a function of (1) such company’s NTM EV/EBITDA, and (2) such company’s NTM P/E. For this analysis, Goldman Sachs used the Forecasts for each of the fiscal years 2019 through 2022 to calculate a range of implied present values per share of Company common stock as of March 31, 2019. Goldman Sachs first calculated illustrative implied future equity values per share of Company common stock as of March 31, 2019 by applying NTM EV/EBITDA multiples ranging from 14.0x to 18.0x to estimated adjusted earnings before interest expense, income taxes, depreciation and amortization (which is referred to in this section as “Adjusted EBITDA”) for each of the fiscal years 2020 to 2022. These illustrative multiple estimates were derived by Goldman Sachs utilizing its professional judgment and experience, taking into account, among other things, current and historical NTM EV/EBITDA multiples for common stock during thetwo-year period ended July 5, 2019 for the Company and the selected companies which, for the purpose of analysis, may be considered similar to certain operations of the Company and which are summarized above. Goldman Sachs then subtracted estimated net debt for each of the fiscal years 2019 to 2021, as provided by management of the Company, as of the relevantyear-end per the Forecasts, from the respective implied enterprise values in order to derive a range of illustrative equity values for the Company for each of the fiscal years 2019 to 2021. Goldman Sachs then divided the results by the projectedyear-end fully diluted shares outstanding for the Company’s common stock, as reflected in the Forecasts, to derive a range of implied future share prices. These implied per share values were then discounted back to March 31, 2019, using an illustrative discount rate of 9.5%, reflecting an estimate of the Company’s cost of equity. Goldman Sachs derived this discount rate by applying the Capital Asset Pricing Model, which requires certain company-specific inputs, including a beta for the company and certain financial metrics for the United States financial markets generally. This analysis resulted in a range of illustrative implied present values per share of Company common stock of $44.99 to $76.30.

Goldman Sachs also calculated illustrative implied future equity values per share of Company common stock as of March 31, 2019 by applying NTM P/E multiples ranging from 20.0x to 25.0x to estimated futureNon-GAAP earnings per share (which is referred to in this section as “Non-GAAP EPS”) for each of the fiscal years 2020 to 2022, to derive a range of implied future share prices. These illustrative multiple estimates were derived by Goldman Sachs utilizing its professional judgment and experience, taking into account, among other things, current and historical NTM P/E multiples for common stock during thetwo-year period ended July 5, 2019 for the Company and the selected companies which, for the purpose of analysis, may be considered similar to certain operations of the Company and which are summarized above. These implied per share values were then discounted back to March 31, 2019, using an illustrative discount rate of 9.5%, reflecting an estimate of the Company’s cost of equity. Goldman Sachs derived this discount rate by applying the Capital Asset Pricing Model, which requires certain company-specific inputs, including a beta for the company and certain financial metrics for the United States financial markets generally. This analysis resulted in a range of illustrative implied present values per share of Company common stock of $45.23 to $80.21.

55

Illustrative Discounted Cash Flow Analysis

Using the Forecasts, Goldman Sachs performed an illustrative discounted cash flow analysis on the Company. Using discount rates ranging from 9.0% to 10.0%, reflecting estimates of the Company’s weighted average cost of capital, Goldman Sachs discounted to present value as of March 31, 2019 (i) estimates of unlevered free cash flow for the Company for April 1, 2019 through December 31, 2024 reflected in the Forecasts and (ii) a range of illustrative terminal values for the Company, which were calculated by applying perpetuity growth rates ranging from 2.75% to 3.75%, to a terminal year estimate of the free cash flow to be generated by the Company, as reflected in the Forecasts. Goldman Sachs derived such range of discount rates by application of the Capital Asset Pricing Model, which requires certain company-specific inputs, including the Company’s target capital structure weightings, the cost of long-term debt,after-tax yield on permanent excess cash, if any, future applicable marginal cash tax rate and a beta for the Company and certain financial metrics for the United States financial markets generally. The range of perpetuity growth rates was estimated by Goldman Sachs utilizing its professional judgment and experience, taking into account the Forecasts and market expectations regarding long-term real growth of gross domestic product and inflation. Goldman Sachs derived ranges of illustrative enterprise values for the Company by adding the ranges of present values it derived above. Goldman Sachs then subtracted the net debt of the Company as of March 31, 2019, as provided by the management of the Company, to derive a range of illustrative equity values for the Company. Goldman Sachs then divided the range of illustrative equity values it derived by the number of fully diluted outstanding shares of the Company, as provided by the management of the Company. This analysis resulted in a range of illustrative values per share of Company common stock of $56.39 to $73.74.

Selected Transactions Analysis

Goldman Sachs analyzed certain information relating to selected transactions in the optical and high-growth semiconductor industries since September 2011. For each of the selected transactions, Goldman Sachs calculated and compared the implied EV/NTM EBITDA multiple of the applicable target company based on the total consideration paid in the transaction as a multiple of the target company’s NTM EBITDA based on Institutional Brokers’ Estimate System estimates at the time each such selected transaction was announced. While none of the target companies that participated in the selected transactions are directly comparable to the Company, the target companies that participated in the selected transactions are companies with operations that, for the purpose of analysis, may be considered similar to certain of the Company’s results, market size and product profile.

56

The following table presents the results of this analysis

Date Announced	Target		Acquiror		NTM Transaction EBITDA Multiple
Optical1
November 2018		Finisar Corporation		II-VI Incorporated		12.4x
March 2018		Oclaro Japan, Inc.		Lumentum Holdings Inc.		11.6x
April 2016		Alliance Fiber Optic Products, Inc.		Corning Incorporated		11.1x
March 2016		Rofin-Sinar Technologies, Inc.		Coherent, Inc.		11.2x
November 2014		Oplink Communications, Inc.		Koch Industries, Inc.		9.2x
High Growth Semiconductor
March 2019		Mellanox Technologies, Ltd.		Nvidia Corp.		14.8x
March 2019		Quantenna Communications Inc.		ON Semiconductor Corporation		22.7x
November 2017		Cavium, Inc.		Marvell Technology Group Ltd.		15.3x
September 2011		NetLogic Microsystems, Inc.		Broadcom Corporation		24.4x

Based on the results of the foregoing calculations and Goldman Sachs’ analyses of the various transactions and its professional judgment, Goldman Sachs applied a reference range of EV/NTM EBITDA multiples of 11.0x (the approximate median of the selected transactions involving optical companies) to 19.0x (the approximate median of the selected transactions involving high growth semiconductor companies) to the Company’s NTM Adjusted EBITDA as of March 31, 2019, as reflected in the Forecasts, to derive a range of implied enterprise values for the Company. Goldman Sachs then subtracted the net debt of the Company as of March 31, 2019, as provided by the management of the Company, to derive a range of illustrative equity values for the Company. Goldman Sachs then divided the range of illustrative equity values it derived by the number of fully diluted outstanding shares of the Company, as provided by the management of the Company. This analysis resulted in a range of illustrative values per share of Company common stock of $31.97 to $48.00.

Premia Analysis

Goldman Sachs reviewed and analyzed, using publicly available information, the acquisition premia forall-cash acquisition transactions announced during the five-year period preceding July 5, 2019 involving a public company in the technology sector based in the United States as the target where the disclosed enterprise values for the transaction were greater than $1 billion, which transactions were identified by Thomson SDC. For the entire period, using publicly available information, Goldman Sachs calculated the median, 25th percentile and 75th percentile premia of the prices paid in the transactions relative to the target companies’ stock prices as of certain dates and certain time periods as described below.

Goldman Sachs calculated the median, 25th and 75th percentile premia to the target companies’ last undisturbed closing share price prior to the announcement of the transaction of 30%, 20% and 46% respectively. Using this analysis, Goldman Sachs then applied an illustrative range of acquisition premia of 20% to 46% to the $48.14 closing price per share of the Company common stock as of July 5, 2019, the last completed trading day prior to the date of Goldman Sachs’ opinion. This analysis resulted in a range of illustrative values per share of Company common stock of $57.86 to $70.24.

Goldman Sachs also calculated the median, 25th and 75th percentile premia to the target companies’ highest closing stock prices in the 52 weeks ended July 5, 2019, of 4.7%, (1.5)% and 13.8%, respectively. Using this

¹  Opnext, Inc.’s acquisition by Oclaro, Inc. in 2012 also fell within the transaction criteria utilized by Goldman Sachs, but in Goldman Sachs’ view the NTM EBITDA multiple in such transaction was not meaningful for purpose of this analysis.

57

analysis, Goldman Sachs then applied an illustrative range of acquisition premia of (1.5)% to 13.8% to the $61.04 closing price per share of Company common stock as of April 15, 2019, representing the highest closing trading price per share of Company common stock for the52-week period ended July 5, 2019. This analysis resulted in a range of illustrative values per share of Company common stock of $60.14 to $69.49.

The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Selecting portions of the analyses or of the summary set forth above, without considering the analyses as a whole, could create an incomplete view of the processes underlying Goldman Sachs’ opinion. In arriving at its fairness determination, Goldman Sachs considered the results of all of its analyses and did not attribute any particular weight to any factor or analysis considered by it. Rather, Goldman Sachs made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all of its analyses. No company or transaction used in the above analyses as a comparison is directly comparable to the Company or Parent or the contemplated transaction.

Goldman Sachs prepared these analyses for purposes of Goldman Sachs’ providing its opinion to the board of directors as to the fairness from a financial point of view of the $70.00 in cash per share to be paid to the holders (other than Parent and its affiliates) of shares of the Company common stock pursuant to the merger agreement was fair from a financial point of view to such holders. These analyses do not purport to be appraisals nor do they necessarily reflect the prices at which businesses or securities actually may be sold. Analyses based upon forecasts of future results are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by these analyses. Because these analyses are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties or their respective advisors, none of the Company, Parent, Goldman Sachs or any other person assumes responsibility if future results are materially different from those forecasts.

The merger consideration was determined througharm’s-length negotiations between the Company and Parent and was approved by the board of directors. Goldman Sachs provided advice to the Company during these negotiations. Goldman Sachs did not, however, recommend any specific amount of consideration to the Company or its board of directors or that any specific amount of consideration constituted the only appropriate consideration for the merger.

As described above, Goldman Sachs’ opinion to the board of directors was one of many factors taken into consideration by the board of directors in making its determination to approve the merger agreement. The foregoing summary does not purport to be a complete description of the analyses performed by Goldman Sachs in connection with the fairness opinion and is qualified in its entirety by reference to the written opinion of Goldman Sachs attached asAnnex B.

Goldman Sachs and its affiliates are engaged in advisory, underwriting and financing, principal investing, sales and trading, research, investment management and other financial andnon-financial activities and services for various persons and entities. Goldman Sachs and its affiliates and employees, and funds or other entities they manage or in which they invest or have other economic interests or with which theyco-invest, may at any time purchase, sell, hold or vote long or short positions and investments in securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments of the Company, Parent, any of their respective affiliates and third parties, or any currency or commodity that may be involved in the transaction contemplated by the merger agreement for the accounts of Goldman Sachs and its affiliates and employees and their customers. Goldman Sachs acted as financial advisor to the Company in connection with, and participated in certain of the negotiations leading to, the transaction contemplated by the merger agreement. Goldman Sachs has also provided certain investment banking services to Parent and its affiliates from time to time for which the Investment Banking Division of Goldman Sachs has received, and may receive, compensation, including having acted as financial advisor to Parent in connection with its acquisition of Duo Security, Inc. in October 2018 and as a commercial paper dealer for Parent since 2015. During the two year period ended July 8, 2019, Goldman Sachs has received compensation for financial advisory and/or underwriting services provided by its Investment

58

Banking Division to Parent and/or its affiliates of approximately $2,700,000. Goldman Sachs may also in the future provide investment banking services to the Company, Parent and their respective affiliates for which the Investment Banking Division of Goldman Sachs may receive compensation. In addition, a Director on the Board of Parent is currently affiliated with the Goldman Sachs Group, Inc. as a Director.

The board of directors of selected Goldman Sachs as its financial advisor because it is an internationally recognized investment banking firm that has substantial experience in transactions similar to the merger. Pursuant to a letter agreement dated June 25, 2019, the Company engaged Goldman Sachs to act as its financial advisor in connection with the contemplated transaction. The engagement letter between the Company and Goldman Sachs provides for a transaction fee that is estimated, based on the information available as of the date of announcement, to be approximately $33,600,000, $3,000,000 of which became payable upon the presentation by Goldman Sachs to the board of directors of the final results of the study Goldman Sachs undertook to determine whether it was able to render a fairness opinion, and the remainder of which is contingent upon consummation of the transaction. In addition, the Company has agreed to reimburse Goldman Sachs for certain of its expenses, including attorneys’ fees and disbursements, and to indemnify Goldman Sachs and related persons against various liabilities, including certain liabilities under the federal securities laws.

Financial Forecasts

The Company does not, as a matter of course, publicly disclose financial forecasts as to future financial performance, earnings or other results for extended periods due to, among other reasons, the unpredictability of its business and competitive markets in which it operates, the historic demand volatility in the optical market, limitations of customer order visibility and lack of customer demand forecast predictability, the inherent difficulty of accurately predicting future periods and the likelihood that the underlying assumptions and estimates may prove incorrect. While the Company prepares forecasts periodically for internal budgeting and business planning purposes, such periodic forecasts generally focus on the two to three immediately following fiscal years and are updated from time to time to reflect historical results, product and market developments and any changes to customer forecasts.

However, in connection with the evaluation of a possible transaction, the Company provided the following projections to its directors and their advisors in connection with their consideration of the merger, as well as to Parent and, in the case of the June LRP described below, to Party C, in connection with their due diligence review of the Company.

• Forecasts prepared in March 2019 for the fiscal years ending December 31, 2019 through 2021 (which the Company referred to as the “Long-Range Plan”). The Long-Range Plan was made available to Parent on March 21, 2019. Although the Long-Range Plan was made available to Goldman Sachs during the initial discussions of its potential engagement in late May 2019, it was never used in the financial analyses prepared by Goldman Sachs.

• Updated forecasts prepared in June 2019 for the fiscal years ending December 31, 2019 through 2024 (which the Company referred to as the “June LRP”) to facilitate certain financial analyses by Goldman Sachs, which forecasts reflected product, market and customer developments as of that date. These developments included a slower increase in the production rate for a new Company product due to the complexity of scaling initial production, the potential impact of actions by the U.S. Department of Commerce against Huawei on overall optical market timing and spending expectations in China and ongoing trade discussions between the U.S. and China governments. The June LRP also reflected three additional years of projections to facilitate a discounted cash flow analysis.

These projections contained certain non-public financial forecasts that were prepared by our management.

A summary of the financial forecasts included in the Long-Range Plan and the June LRP has been included below. This summary is not being included in this proxy statement to influence your decision whether to vote for or against the proposal to adopt the merger agreement, but is being included because these financial forecasts

59

were made available to the Company’s directors and their advisors as well as to Parent and Party C. The inclusion of this information should not be regarded as an indication that the Company’s directors or their advisors, or any other person, considered, or now considers, such financial forecasts to be material or to be necessarily predictive of actual future results, and these forecasts should not be relied upon as such. Internal financial forecasts prepared by the Company’s management, upon which the summary financial forecasts included below were based, are subjective in many respects. There can be no assurance that these financial forecasts will be realized or that actual results will not be significantly higher or lower than forecasted.

In addition, the financial forecasts were not prepared with a view toward public disclosure or toward complying with generally accepted accounting principles, which we refer to as GAAP, the published guidelines of the SEC regarding projections or the use of non-GAAP financial measures or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. Neither our independent registered public accounting firm, nor any other independent accountants, have audited, compiled, examined or performed any procedures with respect to the financial forecasts contained herein, nor have they expressed any opinion or any other form of assurance on such information or its achievability.

These financial forecasts were based on numerous variables and assumptions that are inherently uncertain and may be beyond our control. We believe the assumptions that our management used as a basis for this projected financial information were reasonable, and that the bases on which the financial forecasts were prepared reflected the best currently available estimates and judgments of management of the future financial performance of the Company, at the time our management prepared these financial forecasts, given the information our management had at the time. Important factors that may affect actual results and cause these financial forecasts not to be achieved include, but are not limited to, risks and uncertainties relating to our business (including our ability to achieve strategic and product development goals, objectives and targets over the applicable periods), industry performance and historical optical market demand volatility, general business and economic conditions, including the concentrated nature of the Company’s revenue profile and the scope of its dependency on volatile markets like China and the Data Center Interconnect market, international trade and tariff developments, increases in operating expenses to maintain product innovation and expand the product portfolio, the regulatory environment, including actions of the U.S. Department of Commerce, and other factors described in or referenced under “Cautionary Statement Concerning Forward-Looking Information” beginning on page [—] and“—Reasons for the Merger; Recommendation of the Board of Directors” beginning on page [—] and those risks and uncertainties detailed in the Company’s public periodic filings with the SEC. In addition, the forecasts also reflect assumptions that are subject to change and do not reflect revised prospects for our business or our major customers, changes in general business or economic conditions, or any other transaction or event that has occurred or that may occur and that was not anticipated at the time the financial forecasts were prepared. Accordingly, there can be no assurance that these financial forecasts will be realized or that our future financial results will not materially vary from these financial forecasts.

No one has made or makes any representation to any stockholder regarding the information included in the financial forecasts set forth below. We have made no representation to Parent or Merger Sub in the merger agreement concerning these financial forecasts.

We have not updated and do not intend to update or otherwise revise the financial forecasts to reflect circumstances existing after the date when made or to reflect the occurrence of future events, even in the event that any or all of the assumptions on which such forecasts were based are shown to be in error. In light of the foregoing factors and the uncertainties inherent in these projections, stockholders are cautioned not to place undue, if any, reliance on these projections.

In preparing the Long-Range Plan, our management made the following material assumptions:

• Parent becomes a more material customer of the Company and continues to utilize the Company’s new and future roadmap products in its optical based systems. Revenue from Parent increased to 18%

60

of revenue in the first quarter of 2019, up from 14% in fiscal year 2018, and was expected to continue to be more meaningful over the period reflected in the Long-Range Plan.

• Further revenue growth penetration into new and existing customers, as coherent technology gets utilized to facilitate data transmission over shorter distances, but with increased competition, as standards-based interoperability enables more competitors, and expected pricing pressure as a result.

• China remains a large regional revenue base of the Company, but with concentrated customers and a slower growth rate, as domestic capability is favored over U.S. sources, lower-cost optical interconnect solution options are favored and competition increases.

• Expansion of the Company’s product portfolio driving revenue growth through the addition of new customers and entry into new markets, including increased importance of the datacenter market to anticipated revenue growth and diversification.

In preparing the June LRP, our management made the following material assumptions:

• A slower increase in the production rate for a new Company product due to the complexity of scaling initial production.

• Reduced spending due to timing delays in the China optical market caused by recent actions by the U.S. Department of Commerce against Huawei that impact overall China optical infrastructure projects and ongoing trade discussions between the U.S. and Chinese governments.

• Continued expansion of the Company’s product portfolio beyond 2021, including expansion into new product categories and markets, continuing to drive revenue growth through the addition of new customers and new market opportunities.

• Product unit mix shifts toward pluggable modules and semiconductor products as pluggables become more widely adopted across the industry.

• Continuation of gross margin trends and new operating cost investments needed to support development of the product roadmap.

The estimates of adjusted EBITDA, non-GAAP operating income, non-GAAP net income, diluted shares outstanding, non-GAAP earnings per share and unlevered free cash flow constitute non-GAAP financial measures within the meaning of applicable rules and regulations of the SEC. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information presented in compliance with GAAP, and non-GAAP financial measures as used by the Company may not be comparable to similarly titled amounts used by other companies.

The following is a summary of the financial forecasts for the Company prepared by its management and provided to its directors and their advisors as well as to Parent and, in the case of the June LRP, to Party C, as described in the notes below:

Long-Range Plan

	2019
(in millions, except per share data)	Base		Upside(1)		2020		2021
Revenue	$	450	$	475	$	567	$	714
Adjusted EBITDA(2)	$	99	$	93	$	147	$	226
Non-GAAP Operating Income(3)	$	85	$	79	$	132	$	208
Non-GAAP Net Income(4)	$	84	$	81	$	128	$	197
Non-GAAP Earnings Per Share(5)	$	1.98	$	1.93	$	2.99	$	4.48

(1) The “Upside” case reflected management’s estimate at that time of potential upside to its projections if a trade deal with China were completed by July 2019 and if major backbone network upgrade tenders by the China carriers were awarded on time and meaningful deployment commenced in the second half of 2019. The potential scenarios underlying these upside estimates were not consistent with subsequent market developments reflected in the June LRP.

61

(2) Adjusted EBITDA is calculated as net income (loss) as reported on the Company’s consolidated statements of operations before depreciation, interest income, net, and its (benefit) provision for income taxes and excluding the impact of stock-based compensation, warranty and other charges arising from a manufacturing process quality issue, ZTE-related inventory write-offs and subsequent adjustments and certain litigation-related costs and settlement reserves.

(3) Non-GAAP operating income is calculated as income (loss) from operations as reported on the Company’s consolidated statements of operations, excluding the impact of stock-based compensation, warranty and other charges arising from a manufacturing process quality issue, ZTE-related inventory write-offs and subsequent adjustments and certain litigation-related costs and settlement reserves.

(4) Non-GAAP net income is calculated as net income (loss) as reported on the Company’s consolidated statements of operations, excluding the impact of stock-based compensation which is a non-cash charge, as well as warranty and other charges arising from a manufacturing process quality issue, ZTE-related inventory write-offs and subsequent adjustments, certain litigation-related costs and settlement reserves, the tax effects of those excluded items, certain valuation allowance adjustments against deferred tax assets and the effects of tax reform legislation in the fourth quarter of 2017.

(5) Non-GAAP earnings per share is calculated as non-GAAP net income divided by a non-GAAP weighted-average share count, which includes the impact of dilutive stock-based awards for periods in which there was a GAAP net loss resulting in GAAP diluted net loss per share.

(1) The Adjusted EBITDA forecasts also included a value for Adjusted EBITDA for the period of April 1, 2019 to March 31, 2020 of $88 million. Adjusted EBITDA is calculated as net income (loss) as reported on the Company’s consolidated statements of operations before depreciation, interest income, net, and its (benefit) provision for income taxes, and excluding the impact of stock-based compensation, warranty and other charges arising from a manufacturing process quality issue, ZTE-related inventory write-offs and subsequent adjustments and certain litigation-related costs and settlement reserves.

(2) Cash, equivalents and investments is calculated as the sum of cash and cash equivalents, short term marketable securities and long-term marketable securities. Because the Company has no debt and assumes none during the June LRP project period, the “net debt” amounts referenced for purposes of the analyses by Goldman Sachs are simply the negative of the cash, equivalents and investments values corresponding to the applicable year above, or $(481) million for 2019, $(565) million for 2020, $(703) million for 2021, $(886) million for 2022, $(1,099) million for 2023 and $(1,358) million for 2024. In addition, the Company’s net debt as of March 31, 2019 was $(429) million.

(3) Non-GAAP operating income is calculated as income (loss) from operations as reported on the Company’s consolidated statements of operations, excluding the impact of stock-based compensation, warranty and other charges arising from a manufacturing process quality issue, ZTE-related inventory write-offs and subsequent adjustments and certain litigation-related costs and settlement reserves.

(4) Non-GAAP net income is calculated as net income (loss) as reported on the Company’s consolidated statements of operations, excluding the impact of stock-based compensation which is a non-cash charge, as

62

well as warranty and other charges arising from a manufacturing process quality issue, ZTE-related inventory write-offs and subsequent adjustments, certain litigation-related costs and settlement reserves, the tax effects of those excluded items, certain valuation allowance adjustments against deferred tax assets and the effects of tax reform legislation in the fourth quarter of 2017.

(5) Diluted shares outstanding is a non-GAAP weighted-average share count, which includes the impact of dilutive stock-based awards for periods in which there was a GAAP net loss resulting in GAAP diluted net loss per share.

(6) Non-GAAP earnings per share is calculated as non-GAAP net income divided by diluted shares outstanding.

Using the June LRP provided by the Company, Goldman Sachs calculated and assumed unlevered free cash flows for the Company that were approved by the Company for use by Goldman Sachs in its analyses of: $27 million for calendar year 2019; $32 million for calendar year 2020; $80 million for calendar year 2021; $118 million for calendar year 2022; $145 million for calendar year 2023; and $184 million for calendar year 2024. The unlevered free cash flow forecasts calculated and assumed by Goldman Sachs also included a terminal year value of $192 million and a value for unlevered free cash flow for the period of April 1 to December 31, 2019 of $11 million. Unlevered free cash flow is calculated as non-GAAP operating income, less stock-based compensation, less cash taxes, plus depreciation and amortization, less changes in working capital, less capital expenditures.

Closing and Effective Time of the Merger

The closing of the merger will occur no later than the third business day following the satisfaction or waiver of all of the closing conditions set forth in the merger agreement (described in the section entitled “The Merger Agreement — Conditions to the Merger” beginning on page [—]);provided that if such business day would otherwise occur anytime during the final 14 calendar days of a fiscal quarter of Parent or during the final 21 calendar days of a fiscal year of Parent, then Parent may, in its discretion, delay the closing until the first business day following such period so long as each party has delivered to the other party its required closing certifications, irrevocably confirmed in writing to the other party that its conditions to closing have been satisfied or are waived and that it is ready, willing and able to close, with such delayed closing to be subject only to the further condition that the Company shall not have intentionally and materially breached any of its covenants in the merger agreement regarding the operation of the Company’s business between the signing of the merger agreement and the closing during the period in which the closing is delayed. The parties may also agree in writing to close at any other time.

Assuming timely satisfaction of necessary closing conditions, including the approval by our stockholders of the proposal to adopt the merger agreement, we currently anticipate that the merger will be consummated during the second half of Parent’s 2020 fiscal year, or between January 26, 2020 and July 25, 2020. The merger will become effective upon the filing of a certificate of merger with the Secretary of State of the State of Delaware or at such subsequent time or date as Parent and the Company may agree and specify in the certificate of merger, which we refer to as the effective time.

Payment of Merger Consideration and Surrender of Stock Certificates

Promptly, and in any event within three business days, after the effective time of the merger, a letter of transmittal will be mailed to each record holder of shares of Company common stock describing how such holder should surrender such holder’s shares of Company common stock for the merger consideration.

You should not return your stock certificates with the enclosed proxy card, and you should not forward your stock certificates to the exchange agent (described in the section entitled “The Merger Agreement — Payment Procedures” beginning on page [—]) without a letter of transmittal.

If your shares of Company common stock are certificated, you will not be entitled to receive the per share merger consideration until you deliver a duly completed and executed letter of transmittal to the exchange agent and you

63

must also surrender your stock certificate or certificates to the exchange agent. If your shares of Company common stock are held in book entry, which we refer to as uncertificated shares, surrender of any uncertificated shares will be effected in accordance with the exchange agent’s customary procedures with respect to securities that are uncertificated or represented by book entry and no holder of uncertificated shares will be required to deliver a certificate or an executed letter of transmittal to the exchange agent in order to receive the merger consideration to which such holder is otherwise entitled under the merger agreement. If ownership of your shares is not registered in the transfer records of the Company, a check for any cash to be delivered will only be issued if the applicable letter of transmittal is accompanied by all documents reasonably required by the Company to evidence and effect such transfer and to evidence that any applicable stock transfer taxes have been paid.

If you have lost a certificate, or if it has been stolen or destroyed, then before you will be entitled to receive the merger consideration, you will have to make an affidavit of the loss, theft or destruction and, if reasonably required by Parent or the exchange agent, post a bond, in such reasonable and customary amount as Parent or the exchange agent may reasonably direct, as indemnity against any claim that may be made against Parent, the surviving corporation, the exchange agent or any of their respective representatives with respect to such certificate. These procedures will be described in the letter of transmittal that you will receive, which you should read carefully in its entirety.

Interests of Certain Persons in the Merger

In considering the recommendation of the board of directors with respect to the merger agreement, you should be aware that the Company’s directors and executive officers have interests in the merger that may be different from, or in addition to, the interests of our stockholders generally, as more fully described below. The board of directors was aware of these interests and considered them, among other matters, in reaching the determination that the terms and conditions of the merger and the merger agreement were advisable, fair to and in the best interests of the Company and its stockholders and in making their recommendations regarding adoption of the merger and the merger agreement as described in the section entitled “The Merger — Reasons for the Merger; Recommendation of the Board of Directors”beginning on page [—].

Please see the section of this proxy statement entitled “The Merger —Compensation Payable to our Named Executive Officers” beginning on page [—] for additional information with respect to the compensation that our named executive officers may receive in connection with the merger.

Interests With Respect to Company Equity

64

in the event that the exercise price of any such unvested stock option is equal to or greater than the merger consideration, such stock option will be canceled at the effective time, without any consideration being payable in respect thereof and have no further force or effect.

Each RSU and PRSU that is outstanding and vested and has not been settled immediately prior to the effective time of the merger (which includes certain PRSUs with a total stockholder return performance metric that will become vested based on actual results as of the closing of the merger and certain RSUs that will become vested at the closing of the merger) will be canceled at the effective time and converted into the right to receive an amount in cash without interest, equal to the merger consideration, subject to deduction for any required withholding tax.

Outstanding Company Equity Awards Held by Certain Persons

As described above, at the effective time of the merger, (i) each Company stock option that is outstanding, vested and unexercised will be canceled and converted into the right to receive an amount in cash, without interest, equal to the excess, if any, of the merger consideration over the exercise price per share of such stock option, subject to deduction for any required withholding tax;provided that, in the event that the exercise price of any such vested stock option is equal to or greater than the merger consideration, such stock option will be canceled at the effective time, without any consideration being payable in respect thereof and have no further force or effect and (ii) each RSU and PRSU that is outstanding and vested and has not been settled (which includes certain PRSUs with a total stockholder return performance metric that will become vested based on actual results as of the closing of the merger and certain RSUs that will become vested at the closing of the merger) will be canceled and converted into the right to receive an amount in cash, without interest, equal to the merger consideration, subject to deduction for any required withholding tax.

The following table sets forth the cash payments that would be payable at the closing of the merger in respect of Company stock options, RSUs and PRSUs held as of June 30, 2019 by each person who has served as a director or executive officer of the Company since the beginning of our last completed fiscal year and, in the case of stock options and RSUs, assuming vesting of such awards in accordance with their terms through an assumed closing date of the merger of April 25, 2020 and, in the case of certain PRSUs with a total stockholder return

66

(TSR) performance metric, reflecting performance-based vesting of such awards based on the merger consideration of $70.00 per share in accordance with the terms of such awards (and assuming that the Company’s relative percentile TSR achievement against the applicable peer groups as of July 24, 2019, based on that $70.00 per share price, remains unchanged through the assumed closing date of the merger). RSUs granted to Messrs. Shanmugaraj, Gavin, Mikkelsen, Givehchi, Rasmussen and Shah on April 28, 2016, which we refer to as the 2016 RSUs, would, absent a change in control, become vested in full as of May 12, 2020, subject to the executive officer’s continued employment with the Company through such date. Pursuant to the terms of the 2016 RSUs, upon a “change in control” of the Company (as defined in the applicable RSU agreement and including the merger), the vesting of the 2016 RSUs will be accelerated by a period of six months. The 2016 RSUs that remain unvested at the closing of the merger will accelerate at the closing of the merger and are included in the table below. As noted above, all unvested RSUs held by directors will accelerate at the closing of the merger and such RSUs are included in the table below. The amounts shown in the following table do not reflect any future grants, dividends, deferrals or forfeitures that may occur following June 30, 2019 and prior to the closing of the merger.

In addition, as described above at the effective time of the merger, (i) each Company stock option that is outstanding and unvested immediately prior to the effective time of the merger will be canceled and converted into the right to receive an amount in cash, without interest, equal to the excess, if any, of the merger consideration over the exercise price per share of such stock option, subject to deduction for any required withholding tax, payable to the extent, and at the applicable times, such unvested stock option would have become vested under the vesting schedule in place for such stock option immediately prior to the effective time, including under the terms of the CIC plan, and any scheduled retention agreement after giving effect to any applicable employment offer documents received from Parent;provided that, in the event that the exercise price of any such unvested stock option is equal to or greater than the merger consideration, such stock option will be canceled, without any consideration being payable in respect thereof and have no further force or effect and (ii) each RSU and PRSU that is outstanding and unvested immediately prior to the effective time of the merger will be canceled and converted into the right to receive an amount in cash, without interest, equal to the merger consideration, subject to deduction for any required withholding tax, payable to the extent, and at the applicable times, such unvested RSU or PRSU would have become vested under the vesting schedule in place for such RSU or PRSU immediately prior to the effective time, including under the terms of the CIC plan and any scheduled retention agreement after giving effect to any applicable employment offer documents received from Parent.

The following table sets forth the cash payments that could become payable following the closing of the merger in respect of RSUs held as of June 30, 2019 by each person who has served as a director or executive officer of

67

the Company since the beginning of our last completed fiscal year, based on the RSUs reflected in the table below that are expected to remain unvested in accordance with their terms as of an assumed closing date of the merger of April 25, 2020. Based on holdings as of June 30, 2019, none of the following individuals will hold unvested stock options or unvested PRSUs following the assumed closing date of the merger of April 25, 2020.

Severance/ Change in Control Benefits and Employment Agreements

Pursuant to (i) the CIC plan and (ii) the employment agreements into which Parent (or an affiliate thereof) has entered with certain of the Company’s executive officers, the Company’s executive officers are entitled to specified benefits in the event of the termination of their employment under specified circumstances, including a termination of employment following a change in control of the Company. As described below, Messrs. Shanmugaraj, Mikkelsen, Givehchi and Rasmussen have entered into employment agreements with Parent or its affiliates that become effective upon the closing of the merger and will supersede the offer letters and employment agreements between such executive officers and the Company at such time. Pursuant to those employment agreements, the specified executives waived their rights to participation in, and benefits under, the CIC plan and are instead entitled to the benefits under their employment agreements with Parent following the closing of the merger. Messrs. Gavin, Fisher and Shah currently remain participants under the CIC plan. Additionally, as described above, (i) the 2016 RSUs granted to Messrs. Shanmugaraj, Gavin, Mikkelsen, Givehchi, Rasmussen and Shah will accelerate by a period of six months upon the closing of the merger and (ii) certain PRSUs with a total stockholder return performance metric held by each of the executive officers will become vested based on actual results as of the closing of the merger.

CIC Plan

The CIC plan provides severance benefits to the Company’s executive officers, including certain of the Company’s named executive officers, if their employment is terminated by the Company without “cause” (as defined in the CIC plan) or if they terminate their employment with the Company for “good reason” (as defined in the CIC plan), and additional severance benefits if such terminations occur within one year of a “change in control” (as defined in the CIC plan) of the Company. For purposes of the CIC plan, the merger will constitute a change in control of the Company.

68

Under the CIC plan, if the Company terminates an eligible executive officer’s employment without cause prior to or more than 12 months following the closing of a change in control of the Company, which we refer to as an “involuntary termination,” the executive officer is entitled to:

• continue receiving his or her base salary for a specified period following the date of termination (in the case of the Company Chief Executive Officer, for 12 months, and in the case of all other participants, for nine months);

• Company contributions to the cost of health care continuation under the Consolidated Omnibus Budget Reconciliation Act, or COBRA, for U.S.-based eligible executive officers, or substantially equivalent medical benefits fornon-U.S.-based eligible executive officers, for up to 12 months following the date of termination of employment (or, to the extent anon-U.S. based eligible executive officer is then receiving a stipend from the Company in lieu of benefits coverage, continued payment of such stipend for up to 12 months following the date of termination of employment); and

• the amount of any unpaid annual bonus determined by the board of directors to be payable to the executive officer for any completed bonus period which ended prior to the date of such executive officer’s termination.

In addition, under the terms of the CIC plan, in the case of an involuntary termination, all the executive officer’s outstanding equity awards that vest solely based on the passage of time will be accelerated and become vested to the extent the award would have vested if the executive had remained employed through a specified period following the date of termination (in the case of the Company’s Chief Executive Officer, for 12 months, and, in the case of all other participants, for nine months). The vesting of outstanding performance-based equity awards in connection with an involuntary termination is determined in accordance with the terms of the applicable award agreements.

The CIC plan also provides that, if, within 12 months following a change in control of the Company, the Company terminates an eligible executive officer’s employment without cause or such executive terminates his or her employment with the Company for good reason, which we refer to as a “change in control termination,” the executive is entitled to the following benefits;provided that, as noted above, each of Messrs. Shanmugaraj, Mikkelsen, Givehchi and Rasmussen have entered into employment agreements with Parent or its affiliates that become effective upon the closing of the merger and supersede the CIC plan such that each of Messrs. Shanmugaraj, Mikkelsen, Givehchi and Rasmussen will not be entitled to the following benefits upon a qualifying termination of employment following the merger and will instead be entitled to the benefits described further below in the description of the Parent employment agreements:

• a singlelump-sum payment in an amount equal to 100% of his or her annual base salary;

• a singlelump-sum payment in an amount equal to 100% of his or her target annual bonus for the year in which the termination of employment occurs;

• Company contributions to the cost of health care continuation under COBRA for U.S.-based eligible executive officers, or substantially equivalent medical benefits fornon-U.S. based eligible executive officers, for up to 12 months following the date of termination of employment (or, to the extent anon-U.S. based eligible executive officer is then receiving a stipend from us in lieu of benefits coverage, continued payment of such stipend for up to 12 months following the date of termination of employment); and

• the amount of any unpaid annual bonus determined by the board of directors to be payable to the executive officer for any completed bonus period which ended prior to the date of such executive officer’s termination.

In addition, under the terms of the CIC plan, in the case of a change in control termination, all of the executive officer’s outstanding unvested time-based equity awards will immediately vest in full on the date of such termination. The vesting of outstanding performance-based equity awards in connection with a change in control termination is determined in accordance with the terms of the applicable award agreements.

69

Each executive is also entitled to certain severance benefits upon a termination of employment due to death or disability (as described in the CIC plan), which severance benefits are not enhanced in connection with a change in control of the Company.

All payments and benefits provided under the CIC plan are contingent upon the execution and effectiveness of a release of claims by the executive officer in the Company’s favor and continued compliance by the executive officer with any proprietary information and inventions, nondisclosure,non-competition,non-solicitation (or similar) agreement to which the Company and the executive are party.

Employee Offer Letter and Employee Agreements with the Company

The Company has entered into employee offer letters with each of its executive officers, including its named executive officers, other than one executive officer, Christian J. Rasmussen (whose primary location of employment is Denmark), pursuant to which such executive officers are employed “at will,” meaning that, subject to any statutorily imposed notice period, the executive officer or the Company may terminate the employment arrangement at any time. Such offer letters establish the executive officer’s title, initial compensation arrangements and eligibility for benefits made available to employees generally. Because employment agreements are required under Danish law, the Company, through its wholly owned subsidiary Acacia Communications Europe A/S, entered into an employment agreement with Christian J. Rasmussen, which is generally consistent with the offer letters provided to our other named executive officers, except that the employment agreement provides for a statutorily required six months’ notice period prior to the termination of Mr. Rasmussen’s employment by the Company or by Mr. Rasmussen (which would run concurrently with any severance period applicable to Mr. Rasmussen). As noted above, Parent has entered into employment agreements with each of Messrs. Shanmugaraj, Mikkelsen, Givehchi and Rasmussen, which employment agreements will become effective upon the closing of the merger and will supersede the CIC plan and, as applicable, the offer letters and employment agreements between such executive officers and the Company at such time.

Parent Employment Agreement for Murugesan “Raj” Shanmugaraj

Change in Control Benefits Under Performance-Based Restricted Stock Units

In each of 2018 and 2019 as part of the annual equity grant process, the Company granted PRSUs to the Company’s executive officers under the Company’s 2016 Equity Incentive Plan. The number of PRSUs that vest is measured based on the Company’s percentile achievement of relative total stockholder return, or TSR, against a peer group over a three-year performance period running from January 1, 2018 to December 31, 2020 in the case of the 2018 awards, which we refer to as the 2018 PRSUs, and from January 1, 2019 to December 31, 2021 in the case of the 2019 awards, which we refer to as the 2019 PRSUs. We refer to the 2018 PRSUs and 2019

75

PRSUs together as the TSR PRSUs. The number of shares that may be earned under the TSR PRSUs ranges from 0% to 200% of the target numbers of shares subject to the awards depending on the level of achievement of the TSR performance metric.

Pursuant to the PRSU agreements with respect to the TSR PRSUs, in the event of a “change in control” (as defined in the CIC plan) during the applicable performance period pursuant to which consideration is received by holders of Company common stock, the performance period will be deemed to end upon the closing date of the change in control. For purposes of determining the Company’s TSR pursuant to the applicable TSR PRSU agreement, the “ending price” (as defined in the applicable agreement) of the Company’s common stock will be determined based on the price to be paid to holders of Company common stock in connection with the change in control, as determined by the Company’s compensation committee.

For purposes of the TSR PRSU agreements, the merger will constitute a change in control of the Company and the per share merger consideration will be the “ending price” as defined in such agreements. The Company’s share price performance based on the per share merger consideration will be compared to share price performance of the peer groups on or shortly prior to the closing of the merger to determine the level of achievement of the TSR PRSUs and the number of TSR PRSUs that will vest immediately prior to the merger. Any such TSR PRSUs for which performance has been achieved will vest immediately prior to the change in control and any such TSR PRSUs that do not so vest will be cancelled at such time for no consideration.

Change in Control Benefits under the 2016 RSUs

On April 28, 2016, the Company granted certain RSUs to Messrs. Shanmugaraj, Gavin, Mikkelsen, Givehchi, Rasmussen and Shah, which 2016 RSUs would, absent a change in control, become vested in full as of May 12, 2020, subject to the executive officer’s continued employment with the Company through such date. Pursuant to the terms of the 2016 RSUs, upon a “change in control” of the Company (as defined in the applicable RSU agreement and including the merger), the vesting of unvested 2016 RSUs will be accelerated by a period of six months.

Employee Benefits

Pursuant to the merger agreement, Parent will, or will cause the surviving corporation and its other affiliates to, assume and honor the obligations of the Company and its subsidiaries under the CIC plan and other specified contracts, providing for the payment of severance set forth in accordance with their terms, and to honor all provisions with respect to vesting, accelerated vesting under the CIC plan and any retention agreement and/or payment of any options to purchase shares of Company common stock, RSUs or PRSUs, in each case, unvested as of the effective time of the merger, following the merger and cause all such provisions to apply to payment of the per share merger consideration with respect to such unvested equity awards to the same extent as if the applicable unvested equity awards had been assumed by Parent under the merger agreement, subject in each case to the right to make amendments or modifications to the extent permitted by such terms and subject to any applicable agreements entered into between any employees of the Company and its subsidiaries as of the effective time of the merger (which we refer to as continuing employees).

For a more detailed description of these provisions of the merger agreement, please see the section of the proxy statement entitled “The Merger Agreement — Additional Agreements of the Parties to the Merger Agreement — Employee Benefits Matters” on page [—].

Indemnification of Directors and Officers

The merger agreement provides that, from and after the effective time of the merger until the sixth anniversary of the effective time of the merger, Parent will assume, and will cause the surviving corporation to honor and fulfill in all respects all rights to indemnification by the Company and its subsidiaries to their respective present and

76

former directors and officers pursuant to any indemnification agreements with the Company or such subsidiary made available to Parent and any indemnification or advancement provisions under the Company’s or such subsidiary’s certificate of incorporation or bylaws (or equivalent organizational documents) as in effect on the date of the merger agreement with respect to their acts and omissions as directors and officers of the Company or such subsidiary occurring prior to the effective time of the merger, in each case, subject to applicable law.

For a more detailed description of these provisions of the merger agreement, please see the section of this proxy statement entitled “The Merger Agreement — Additional Agreements of the Parties to the Merger Agreement —Indemnification and Insurance” on page [—].

Intent to Vote in Favor of the Merger

As of the record date, the directors and executive officers of the Company beneficially owned and were entitled to vote, in the aggregate, [—] shares of Company common stock, representing approximately [—]% of the outstanding shares of Company common stock on the record date. The directors and executive officers have informed the Company that they currently intend to vote all of their shares of Company common stock “FOR” the proposal to adopt the merger agreement, “FOR” approval of the nonbinding advisory proposal regarding compensation that may be payable to our named executive officers in connection with the merger and “FOR” the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies. In addition, the shares described above include shares beneficially owned by Murugesan Shanmugaraj, Benny Mikkelsen, Christian Rasmussen and Mehrdad Givehchi (including certain entities holding shares of Company common stock on their behalf) and such stockholders are obligated, pursuant to voting agreements entered into on July 8, 2019 between Parent and each of such stockholders, to vote such shares in favor of the adoption of the merger agreement and any matter that would reasonably be expected to facilitate the merger.

Compensation Payable to our Named Executive Officers

This section sets forth the information required by Item 402(t) of RegulationS-K regarding the compensation for each of our named executive officers that is based on or otherwise relates to the merger. This compensation is referred to as compensation that may be payable to our named executive officers in connection with the merger. The amounts set forth in the table are estimates based on multiple assumptions that may or may not actually occur, including assumptions described in this proxy statement and in the footnotes to the table. As a result, the actual amounts, if any, that an executive officer receives may materially differ from the amounts set forth in the table.

The table below describes the estimated potential payments to each of our named executive officers pursuant to the terms of their 2016 RSUs, their TSR PRSUs and under the CIC plan or the terms of their respective employment agreements with Parent, as applicable. The amounts shown in the table do not include the value of payments or benefits that would have been earned, or any amounts associated with equity awards that would vest pursuant to their terms, on or prior to the effective date of the merger or the value of payments or benefits that are not based on or otherwise related to the merger.

For purposes of calculating the potential payments set forth in the table below, the Company has assumed that (i) the merger will become effective on, and the date of termination of employment of the named executive officers is, April 25, 2020; (ii) the termination of employment is a change in control termination pursuant to the CIC plan or a termination that results in severance benefits pursuant to the named executive officer’s employment agreement with Parent, as applicable, (iii) the stock price is $70.00 per share, which is the per share merger consideration; (iv) for purposes of calculating the number of TSR PRSUs that will vest, the Company’s percentile TSR achievement against the applicable peer groups as of July 24, 2019 (based on an ending price for the Company common stock of $70.00 per share) remains unchanged through the assumed effective date of the merger; and (v) no withholding taxes are applicable to any payments set forth in the table. The amounts shown in the table are estimates only and are based on assumptions and information available to date. The actual amounts

77

that may be paid upon an individual’s termination of employment can only be determined at the actual time of such termination.

1) The amounts listed in this column represent, for Messrs. Shanmugaraj, Mikkelsen, and Givehchi, cash severance amounts that are payable pursuant to their respective employment agreements with Parent which become effective upon the closing of the merger and which are payable if, within the first 12 months following the closing of the merger, Parent terminates the executive’s employment without cause or if he resigns his employment for good reason, as such terms are defined in the applicable employment agreement, and therefore such amounts are “double trigger” benefits. Such cash severance amounts are paid in a lump sum and for Mr. Shanmugaraj include (a) 200% of his annual base salary, (b) 150% of his target annual bonus and (c) an amount equal to any unpaid annual bonus in respect of any completed bonus period which has ended prior to the date of termination. For Messrs. Mikkelsen and Givehchi, such cash severance amounts include (a) 100% of the executive officer’s annual base salary, (b) 100% of the executive officer’s target annual bonus and (c) an amount equal to any unpaid annual bonus in respect of any completed bonus period which has ended prior to the date of termination.

The amounts listed in this column represent, for Messrs. Gavin and Fisher, cash severance payments that are payable under the CIC plan upon a change in control termination and therefore such amounts are “double trigger” benefits. For this purpose, a “change in control termination” occurs when, within 12 months following a change in control of the Company, the Company terminates an eligible executive officer’s employment without cause or such executive terminates his employment with the Company for good reason, as such terms are defined in the CIC plan. Such cash severance payments are paid in a lump sum and for each of Messrs. Gavin and Fisher include (a) 100% of the executive officer’s annual base salary, (b) 100% of the executive officer’s target annual bonus for the year in which the termination of employment occurs and (c) the amount of any unpaid annual bonus determined by the board of directors to be payable to the executive officer for any completed bonus period which ended prior to the date of such executive’s termination.

The amounts listed in this column were calculated assuming that the annual base salary and target annual bonus for each named executive officer entitled to severance under the CIC plan or his employment agreement with Parent effective as of the assumed closing date of the merger of April 25, 2020 are equal to, for Messrs. Shanmugaraj, Mikkelsen and Givehchi, the amounts provided for under their respective employment agreements entered into with Parent in connection with the merger, and for Messrs. Gavin and Fisher, the amounts pursuant to their current employment arrangements with the Company, which amounts are set forth in the table below.

Name	Base Salary($)		Target Annual Bonus($)
Murugesan “Raj” Shanmugaraj		350,000		327,250
John F. Gavin		372,500		242,125
Eric Fisher		354,800		230,620
Benny P. Mikkelsen		320,000		230,620
Mehrdad Givehchi		300,000		215,020

2) The amounts listed in this column represent, in accordance with the terms of the TSR PRSU award agreements, the 2016 RSU agreements, and the CIC plan or the named executive officers’ employment agreements with Parent, as applicable, the cash payments in respect of (a) the cash payment for cancellation of unvested 2016 RSUs, which RSUs accelerate upon the merger, calculated as the product of (i) the per share merger consideration of $70.00 multiplied by (ii) the number of accelerated 2016 RSUs with respect to which such cash payments are being made, which amounts are “single trigger” benefits payable upon the closing of the merger; (b) the accelerated cash payment for cancellation of unvested RSUs held by each executive officer, calculated as the product of (i) the per share merger consideration of $70.00 multiplied by (ii) the number of unvested RSUs with respect to which such cash payments are being made, which amounts are “double trigger” benefits payable upon certain terminations of employment following the closing of the merger, as described below; and (c) the settlement of the TSR PRSUs pursuant to their terms, calculated as the product of (i) the per share merger consideration of $70.00 multiplied by (ii) the number of TSR PRSUs that vest immediately prior to the effective time pursuant to the terms of the applicable TSR PRSU award agreements, which amounts are “single trigger” benefits payable upon the closing of the merger.

The accelerated cash payments for cancellation of unvested RSUs (other than the accelerated vesting of the 2016 RSUs) are “double-trigger” benefits and (i) for each of Messrs. Shanmugaraj, Mikkelsen and Givehchi are payable pursuant to his employment agreement with Parent, within the first 12 months following the closing of the merger, if Parent terminates the executive’s employment without cause, if he resigns his employment for good reason, or if his employment is terminated due to his death or permanent disability, as such terms are defined in the applicable employment agreement and (ii) for each of Messrs. Gavin and Fisher are payable pursuant to the CIC plan upon a change in control termination. For this purpose, a “change in control termination” occurs when, within 12 months following a change in control of the Company, the Company terminates an eligible executive’s employment without cause or such executive terminates his employment with the Company for good reason, as such terms are defined in the CIC plan.

The number of 2016 RSUs that accelerate upon the merger, unvested RSUs and TSR PRSUs held by each named executive officer to be treated as described in this note 2 and the cash payments payable with respect to such RSUs and TSR PRSUs are as follows:

Name	Vested 2016 RSUs (Single Trigger)		Value of Vested 2016 RSUs (Single Trigger)		Unvested RSUs at Closing (Double Trigger)		Value of Unvested RSUs at Closing (Double Trigger)		Vested TSR PRSUs (Single Trigger)		Value of Vested TSR PRSUs (Single Trigger)
Murugesan “Raj” Shanmugaraj		15,000	$	1,050,000		46,131	$	3,229,170		38,896	$	2,722,720
John F. Gavin		12,500	$	875,000		30,038	$	2,102,660		25,052	$	1,753,640
Eric Fisher		0	$	0		41,725	$	2,920,750		31,218	$	2,185,260
Benny P. Mikkelsen		12,500	$	875,000		28,831	$	2,018,170		24,308	$	1,701,560
Mehrdad Givehchi		12,500	$	875,000		28,831	$	2,018,170		24,308	$	1,701,560

3) The amounts in this column represent, for Messrs. Shanmugaraj, Mikkelsen and Givehchi, the total COBRA premiums required to continue the executive’s group health care coverage for him and his eligible dependents for a period of 12 months. For Messrs. Gavin and Fisher, the amount in this column represents the Company contributions to the cost of health care continuation under COBRA for 12 months for the executive. These amounts are “double trigger” in nature for each of the named executive officers and are payable, in the case of Messrs. Shanmugaraj, Mikkelsen and Givehchi, within the first 12 months following the closing of the merger, if Parent terminates the executive’s employment without cause or if he resigns his employment for good reason, as such terms are defined in the applicable employment agreement, and for Messrs. Gavin and Fisher upon a change in control termination under the CIC plan.

4) The amounts in this column represent, for Messrs. Shanmugaraj, Mikkelsen and Givehchi, the tax gross up payments that each would be entitled to receive from the Company with respect to the payments of COBRA premiums described in note 3 above. These amounts are “double trigger” in nature for Messrs.

79

Shanmugaraj, Mikkelsen and Givehchi, within the first 12 months following the closing of the merger, if Parent terminates the named executive officer’s employment without cause or if he resigns his employment for good reason, as such terms are defined in the applicable employment agreement.

Accounting Treatment

The merger will be accounted for as a “purchase transaction” for financial accounting purposes.

U.S. Federal Income Tax Consequences of the Merger

The following is a summary of the U.S. federal income tax consequences of the merger to “U.S. holders” and certain“non-U.S. holders” (both terms defined below) whose shares of our common stock are converted into the right to receive cash pursuant to the merger. This summary is for information purposes only and is not tax advice. It does not purport to consider all aspects of U.S. federal income taxation that might be relevant for holders of our common stock. This summary is based on the Internal Revenue Code of 1986, as amended, which we refer to as the Code, the applicable U.S. Treasury regulations promulgated under the Code, published rulings by the Internal Revenue Service, which we refer to as the IRS, and judicial authorities and administrative decisions, all as in effect as of the date of this proxy statement and all of which are subject to change or differing interpretations, possibly with retroactive effect. Any such change could alter the tax consequences to the holders described herein. This summary is not binding on the IRS or a court, and there can be no assurance that the tax consequences described in this summary will not be challenged by the IRS or that they would be sustained by a court if so challenged. No ruling has been or will be sought from the IRS, and no opinion of counsel has been or will be rendered, as to the U.S. federal income tax consequences of the merger.

For purposes of this summary, the term “U.S. holder” means a beneficial owner of shares of our common stock that is, for U.S. federal income tax purposes:

• an individual who is a citizen or resident of the United States;

• a corporation (including any entity treated as a corporation for U.S. federal income tax purposes) created or organized under the laws of the United States, any state thereof or the District of Columbia;

• a trust that (a) is subject to the primary supervision of a court within the United States and all substantial decisions of which are controlled by one or more U.S. persons or (b) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person; or

• an estate the income of which is subject to U.S. federal income tax regardless of its source.

As used herein, a“non-U.S. holder” means a beneficial owner of shares of our common stock that is neither a U.S. holder nor an entity or arrangement treated as a partnership for U.S. federal income tax purposes.

If a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds our common stock, the tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. A partner of a partnership holding our common stock should consult the partner’s tax advisor regarding the U.S. federal income tax consequences of the merger to such partner.

This summary applies only to holders who hold shares of our common stock as capital assets within the meaning of Section 1221 of the Code (generally, property held for investment), and does not address or consider all of the U.S. federal income tax consequences that may be applicable to holders of our common stock in light of their particular circumstances. For instance, this summary does not address the alternative minimum tax or the tax consequences to stockholders who validly exercise dissenters’ rights under the DGCL. In addition, this summary does not address the U.S. federal income tax consequences of the merger to holders who are subject to special treatment under U.S. federal income tax rules, including, for example, banks and other financial institutions; insurance companies; securities dealers or broker-dealers; mutual funds; traders in securities who elect to use the

80

mark-to-market method of accounting;tax-exempt investors; S corporations; holders classified as partnerships or other flow-through entities under the Code; U.S. expatriates; holders who hold their shares of our common stock as part of a hedge, straddle, conversion transaction, or other integrated investment or constructive sale transaction; holders whose functional currency is not the U.S. dollar; holders who acquired their shares of our common stock through the exercise of Company stock options or otherwise as compensation; and, except to the extent described below, holders who actually or constructively own 5% or more of the outstanding shares of our common stock. In addition, this summary does not address the impact of the Medicare contribution tax, any aspects of foreign, state, local, estate, gift, or other tax laws (or any U.S. federal tax laws other than those pertaining to income tax) that may be applicable to a particular holder in connection with the merger.

Further, this summary does not address any tax consequences of the merger to holders of options or restricted stock units whose options or restricted stock units are cancelled in exchange for cash pursuant to the merger. Such option and restricted stock unit holders should consult their tax advisors regarding the tax consequences of the merger to them. Moreover, this summary does not discuss any other matters relating to equity compensation or benefit plans (including our 401(k) plan).

U.S. Holders

A U.S. holder’s receipt of the per share merger consideration in exchange for shares of our common stock will generally be a taxable transaction for U.S. federal income tax purposes. In general, a U.S. holder whose shares of common stock are converted into the right to receive cash pursuant to the merger will recognize capital gain or loss for U.S. federal income tax purposes in an amount equal to the difference, if any, between the amount of cash received (determined before deduction of any applicable withholding taxes) with respect to such shares and the U.S. holder’s adjusted tax basis in such shares. A U.S. holder’s adjusted tax basis will generally equal the price the U.S. holder paid for such shares. The amount of gain or loss must be determined separately for each block of shares (i.e., shares acquired at the same cost in a single transaction) surrendered by the U.S. holder in the merger. Such gain or loss will generally be long-term capital gain or loss if the U.S. holder’s holding period for such shares is more than 12 months at the effective time of the merger. Long-term capital gains recognized by individual and certain othernon-corporate U.S. holders are generally taxed at preferential U.S. federal income tax rates. A U.S. holder’s ability to deduct capital losses may be limited.

Non-U.S. Holders

Cash received in the merger by anon-U.S. holder generally will not be subject to U.S. withholding tax (other than potentially to backup withholding tax or FATCA withholding, as discussed below) and will not be subject to U.S. federal income tax unless:

• the gain is effectively connected with a trade or business of thenon-U.S. holder in the United States (and, if an income tax treaty applies, is attributable to a United States permanent establishment maintained by suchnon-U.S. holder), in which case thenon-U.S. holder generally will be subject to tax on such gain in the same manner as if it were a U.S. holder, and, if thenon-U.S. holder is a foreign corporation, such gain may also be subject to an additional branch profits tax at a rate of 30% or at such lower rate as may be specified by an applicable income tax treaty;

• thenon-U.S. holder is an individual who was present in the United States for 183 days or more in the taxable year of the merger and certain other conditions are met, in which case thenon-U.S. holder generally will be subject to a 30% tax (or such lower rate as may be specified by an applicable income tax treaty between the United States and such holder’s country of residence) on the net gain derived from the disposition, which may be offset by certain U.S.-source capital losses of thenon-U.S. holder recognized in the taxable year of the disposition, if any; or

• the Company was a “United States real property holding corporation”, which we refer to as a USRPHC, within the meaning of Section 897(c)(2) of the Code for U.S. federal income tax purposes

81

within the five years preceding the merger and thenon-U.S. holder owned, actually or constructively, more than 5% of the Company common stock at any time during the five-year period preceding the merger. In general, the Company would be a USRPHC if interests in U.S. real estate comprised most of its assets. Although there can be no assurances in this regard, the Company does not believe it is, or has been during the five years preceding the merger, a USRPHC for U.S. federal income tax purposes.

Non-U.S. holders should consult their own tax advisors regarding the tax consequences to them of the merger.

Backup Withholding and Information Reporting

A U.S. holder may be subject to backup withholding on all payments to which such U.S. holder is entitled in connection with the merger, unless the U.S. holder provides its correct taxpayer identification number and complies with applicable certification procedures or otherwise establishes an exemption from backup withholding. In addition, if the exchange agent is not provided with a U.S. holder’s correct taxpayer identification number or other adequate basis for exemption, the U.S. holder may be subject to certain penalties imposed by the IRS. Each U.S. holder should complete and sign the IRS FormW-9 included as part of the letter of transmittal and timely return it to the exchange agent in order to avoid backup withholding, unless an exemption applies and is established in a manner satisfactory to the exchange agent.

Certainnon-U.S. holders may also be subject to backup withholding unless they establish an exemption from backup withholding in a manner satisfactory to the exchange agent (such as by completing and signing an appropriate IRS FormW-8) and otherwise comply with the backup withholding rules.Non-U.S. holders should consult their own tax advisors regarding these matters.

Backup withholding is not an additional tax. Rather, any amounts withheld under the backup withholding rules will generally be allowable as a refund or credit against a holder’s U.S. federal income tax liability;provided that certain required information is timely furnished to the IRS.

Payments made pursuant to the merger will also be subject to information reporting unless an exemption applies.

FATCA

Provisions of the Code commonly referred to as the Foreign Account Tax Compliance Act, or FATCA, may impose a 30% withholding tax on gross proceeds received in the merger if paid to a foreign entity unless (i) if the foreign entity is a “foreign financial institution,” the foreign entity undertakes certain due diligence, reporting, withholding, and certification obligations, (ii) if the foreign entity is not a “foreign financial institution,” the foreign entity identifies certain of its U.S. investors, or (iii) the foreign entity is otherwise excepted under FATCA. Under recently proposed U.S. Treasury Regulations, withholding on payments of gross proceeds is not required. Although such regulations are not final, applicable withholding agents may rely on the proposed regulations until final regulations are issued.Non-U.S. holders should consult their own tax advisors regarding the possible implications of FATCA on their receipt of cash in the merger.

This summary is provided for general information only and is not tax advice. The U.S. federal income tax consequences described above are not intended to constitute a complete description of all tax consequences relating to the merger. Because individual circumstances may differ, each stockholder should consult the stockholder’s tax advisor regarding the applicability of the rules discussed above to the stockholder and the particular tax effects to the stockholder of the merger in light of such stockholder’s particular circumstances and the application of state, local, foreign, estate, gift and other tax laws (or any U.S. federal tax laws other than those pertaining to income tax).

Regulatory Approvals

The merger is subject to the reporting and waiting period requirements of the HSR Act and obtaining antitrust approval in specified foreign jurisdictions, including Austria, China and Germany. Under the terms of the merger

82

agreement, the merger cannot be consummated if any governmental entity of competent jurisdiction has issued, promulgated or entered any judgment, writ, decree, stipulation, determination, decision, legal or arbitration award, settlement or consent agreement, charge, ruling, injunction, restraining order or other order (whether temporarily, preliminary or permanently in effect), or has enacted any law, statute, constitution, resolution, ordinance, code, permit, rule, regulation, ruling or requirement that prohibits, makes illegal or enjoins the consummation of the merger.

THE MERGER AGREEMENT (PROPOSAL ONE)

The following is a summary of the material terms and conditions of the merger agreement. The description in this section and elsewhere in this proxy statement is qualified in its entirety by reference to the complete text of the merger agreement, a copy of which is attached asAnnex A and is incorporated by reference into this proxy statement. This summary does not purport to be complete and may not contain all of the information about the merger agreement that is important to you. We encourage you to read the merger agreement carefully and in its entirety because it is the legal document that governs the merger.

Explanatory Note Regarding the Merger Agreement

The merger agreement is included to provide you with information regarding its terms. Factual disclosures about the Company contained in this proxy statement or in the Company’s public reports filed with the SEC may supplement, update or modify the factual disclosures about the Company contained in the merger agreement. The representations, warranties and covenants made in the merger agreement by the Company, Parent and Merger Sub were qualified and subject to important limitations agreed to by the Company, Parent and Merger Sub 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 merger if the representations and warranties of the other party prove to be untrue due to a change in circumstance or otherwise, and allocating risk between the parties to the merger agreement, rather than establishing as facts the matters described therein. 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 the matters contained in a disclosure schedule that the Company delivered to Parent in connection with the merger agreement, which we refer to as the Company disclosure schedule. Moreover, information concerning the subject matter of the representations and warranties, which do not purport to be accurate as of the date of this proxy statement, 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 proxy statement.

The Merger

On the terms and subject to the conditions set forth in the merger agreement and the applicable provisions of DGCL, at the effective time of the merger, Merger Sub, a wholly owned subsidiary of Parent, will merge with and into the Company, the separate corporate existence of Merger Sub will cease and the Company will continue as the surviving corporation or the merger. As a result of the merger, the Company will become a wholly owned subsidiary of Parent. We sometimes refer to the Company after the consummation of the merger as the surviving corporation. The certificate of incorporation of the Company will be amended and restated in its entirety at the effective time of the merger, to read as set forth on an exhibit to the merger agreement. Theby-laws of the Company will also be amended and restated in their entirety at the effective time of the merger, to read as set forth on an exhibit to the merger agreement. The directors of Merger Sub immediately prior to the effective time of the merger will be the initial directors of the surviving corporation. The officers of Merger Sub immediately prior to the effective time of the merger will be the initial officers of the surviving corporation.

Effective Time of the Merger

Unless the merger agreement is terminated (as described under “— Termination”) and unless otherwise mutually agreed in writing between the Company, Parent and Merger Sub, subject to satisfaction or waiver of the conditions to the closing (described under “—Conditions to the Merger”), the consummation of the merger (which we refer to as the closing) will take place on the third business day (or as otherwise mutually agreed) after the satisfaction or waiver of the conditions to the closing (other than any such conditions that by their nature are

84

to be satisfied at the closing, but subject to the satisfaction or waiver of such conditions). However, if the closing would otherwise occur anytime during the final 14 calendar days of a fiscal quarter of Parent or during the final 21 calendar days of a fiscal year of Parent, Parent may, in its discretion, delay the closing until the first business day following such period so long as each party has delivered to the other party its required closing certifications, irrevocably confirmed in writing to the other party that its conditions to closing have been satisfied or are waived and that it is ready, willing and able to close, with such delayed closing to be subject only to the further condition that the Company shall not have intentionally and materially breached any of its covenants in the merger agreement regarding the operation of the Company’s business between the signing of the merger agreement and the closing during the period in which the closing is delayed.

The merger will become effective upon the date and time the certificate of merger is accepted by the Secretary of State of the State of Delaware or such later date and time as is agreed upon in writing by the Company and Parent and specified in the certificate of merger.

Merger Consideration

At the effective time of the merger, each share of Company common stock then outstanding will be converted automatically into the right to receive the merger consideration of $70.00 per share in cash upon the surrender of the stock certificates or book-entry shares, as applicable, without interest and subject to all applicable tax withholding, other than the following shares:

• each share of Company common stock then held by the Company as treasury stock and by any of its direct or indirect wholly owned subsidiaries, which will be canceled and retired and will cease to exist, and no consideration will be delivered in exchange therefor;

• each share of Company common stock then held by Parent, Merger Sub or any other subsidiary of Parent, which will be canceled and retired and will cease to exist, and no consideration will be delivered in exchange therefor; and

• any dissenting shares, which are described below in the section entitled “— Appraisal Rights”.

Subject to the above exceptions, from and after the effective time of the merger, each holder of Company common stock outstanding immediately prior to the effective time of the merger will cease to have any rights with respect to such shares, except as otherwise provided in the merger agreement or by applicable law, and such shares will no longer be outstanding and will automatically be canceled.

The merger consideration will be equitably adjusted to the extent necessary to reflect the effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into capital stock), reorganization, reclassification, combination, recapitalization or other like change with respect to the Company common stock occurring after the date of the merger agreement and prior to the effective time of the merger.

Payment Procedures

Parent has designated its transfer agent, Computershare Trust Company, N.A., to act as exchange agent for the holders of shares of Company common stock. At or prior to the effective time of the merger, Parent will deposit or cause its direct or indirect subsidiary to deposit, with such exchange agent cash sufficient to pay the aggregate merger consideration payable to the Company’s stockholders.

Promptly (and in any event within three business days) after the effective time of the merger, Parent will instruct the exchange agent to mail to all record holders of Company common stock represented by stock certificates whose shares were converted into the right to receive the merger consideration, a letter of transmittal and instructions for use in effecting the surrender of the stock certificates pursuant to such letter of transmittal. Each

85

holder of book-entry shares will not be required to deliver a letter of transmittal and instead may provide such evidence, if any, as the exchange agent may reasonably request with respect to its book-entry shares. Upon surrender to the exchange agent of certificates representing shares of Company common stock, together with a letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be reasonably required by the exchange agent, or in the case of book-entry shares, an appropriate agent’s message, the holder of such certificates or book-entry shares will be entitled to receive in exchange therefor the merger consideration for each share of Company common stock evidenced by such certificates or book-entry shares. No interest will accrue or be paid on the merger consideration payable upon the surrender of any certificates or book-entry shares for the benefit of the holder thereof. Each of the surviving corporation, Parent, their respective subsidiaries and the exchange agent will be entitled to deduct and withhold (or cause the exchange agent to deduct and withhold) from the merger consideration payable to any holder of Company common stock, stock options, RSUs, PRSUs or any other consideration otherwise payable pursuant to the merger agreement such amounts as it is required by any legal requirement to deduct and withhold with respect to taxes.

All merger consideration paid or payable upon the surrender for exchange of shares of Company common stock in accordance with the merger agreement will be so paid or payable in full satisfaction of all rights pertaining to such shares, and there will be no further registration of transfers on the records of the surviving corporation of shares of Company common stock that were issued and outstanding immediately prior to the effective time of the merger. If, after the effective time of the merger, any stock certificate or book-entry shares are presented to the surviving corporation for any reason, such stock certificate or book-entry shares will be cancelled and exchanged as provided in this section.

Any portion of funds held by the exchange agent that has not been delivered to any holders of stock certificates or book-entry shares within 12 months after the effective time of the merger will promptly be paid to Parent, and thereafter each holder of a stock certificate or book-entry shares who has not theretofore complied with the exchange procedures set forth in the merger agreement will look only to Parent (subject to abandoned property, escheat and similar laws) for its claim, only as a general unsecured creditor thereof, to the cash payable to such holder pursuant to the merger agreement.

In the event any stock certificate has been lost, stolen or destroyed, the exchange agent will issue in exchange for such stock certificate, following the making of an affidavit of that fact by the record holder thereof, the merger consideration in respect of such stock certificate;provided that Parent or the exchange agent may, in its respective reasonable discretion and as a condition precedent to the issuance thereof, require the record holder of such stock certificate to deliver a customary bond, in such reasonable amount as Parent or the exchange agent may reasonably direct, as indemnity against any claim that may be made against Parent, the surviving corporation, the exchange agent or any of their respective representatives with respect to such certificate.

You should not send your certificates (if any) to the exchange agent until you have received transmittal materials from the exchange agent. Do not return your certificates (if any) with the enclosed proxy.

Appraisal Rights

Shares of Company common stock issued and outstanding immediately prior to the effective time of the merger that are held by a holder who has made a proper demand for appraisal of such shares of Company common stock in accordance with Section 262 of the DGCL, continuously holds such shares of record from the date of the making of the demand through the effective time of the merger and has not thereafter failed to perfect, withdraw or otherwise lose his, her or its rights to appraisal, which we refer to as dissenting shares, will not be converted into or represent the right to receive the merger consideration in accordance with the merger agreement. Holders of dissenting shares will be entitled to have their shares appraised by the Delaware Court of Chancery and to receive in lieu of the merger consideration payment in cash of the amount determined by the Delaware Court of Chancery to be the “fair value” of the shares of Company common stock as of the effective time of the merger.

86

These rights are discussed more fully under the section of this proxy statement entitled “Appraisal Rights” beginning on page [—]. If any dissenting shares lose their status as such (through failure to perfect or otherwise), then, as of the later of the effective time or the date of loss of such status, such shares will be deemed to have been converted as of the effective time into the right to receive the merger consideration in accordance with the merger agreement, without interest and subject to deduction for any required tax withholding, and will not thereafter be deemed to be dissenting shares.

The Company must give Parent: (i) prompt notice of any written demand for appraisal received by the Company prior to the effective time pursuant to the DGCL, withdrawals of such demands and any other instruments served pursuant to the DGCL and received by the Company that relate to such demands, and (ii) the right to participate in all negotiations and proceedings with respect to such demands under the DGCL. The Company may not, except with the prior written consent of Parent, voluntarily make any payment or offer to make any payment with respect to, or settle or offer to settle, any claim or demand in respect of any dissenting shares.

Treatment of Company Equity Awards and Employee Stock Purchase Plan

Each Company stock option that is outstanding, vested and unexercised immediately prior to the effective time of the merger will be canceled at the effective time and converted into the right to receive an amount in cash, without interest, equal to the excess, if any, of the merger consideration over the exercise price per share of such stock option;provided that, in the event that the exercise price of any such vested stock option is equal to or greater than the merger consideration, such stock option will be canceled at the effective time, without any consideration being payable in respect thereof and have no further force or effect.

Definitions of Knowledge and Material Adverse Effect

Many of the Company’s representations and warranties are qualified by a knowledge, materiality or material adverse effect standard. In addition, certain conditions to the performance of Parent’s obligations under the

89

merger agreement are qualified by reference to whether the item in question would have a material adverse effect. For purposes of the merger agreement, “knowledge” means the knowledge of certain specified employees of the Company after reasonable inquiry. For purposes of the merger agreement, “material adverse effect” means with respect to the Company and its subsidiaries, taken as a whole, any change, event, occurrence, circumstance, condition or effect (each referred to as an effect) that, individually or taken together with all other effects, and regardless of whether or not such effect, considered together with all other effects, would constitute a breach of the representations or warranties made by such person in the merger agreement (a) would, or would reasonably be expected to, be or become materially adverse to the financial condition (including assets and liabilities, taken as a whole), business, operations or results of operations of the Company and its subsidiaries, taken as a whole and (b) would, or would reasonably be expected to, prohibit the Company’s ability to consummate the transactions in accordance with the merger agreement and applicable laws. However, the absence of or failure to obtain any consent, approval, waiver or clearance from any governmental entity under antitrust laws with respect to the transactions contemplated under the merger agreement will not constitute a material adverse effect. In addition, none of the following will be deemed in and of themselves, either alone or in combination, to constitute, and none of the following will be taken into account in determining whether there is, or would reasonably likely to be, a material adverse effect on the Company and its subsidiaries:

• changes in general economic conditions or financial, credit, foreign exchange, securities, currency, or capital or other financial markets, including any disruption thereof, in the United States, any other country or region in the world or the global economy generally;

• changes generally affecting the industry in which the Company and its subsidiaries operate;

• changes in applicable laws;

• changes in United States generally accepted accounting principles, or GAAP, or other accounting regulations or principles or interpretations thereof, that apply to the Company and its subsidiaries;

• national or international political conditions, any outbreak or escalation of hostilities, insurrection or war, or acts of terrorism;

• epidemics, quarantine restrictions, wildfires, earthquakes, hurricanes, tornadoes, other natural disasters or similar calamity or crisis;

• changes in the trading volume or trading prices of such entity’s capital stock in and of themselves (however, such exception will not apply to any underlying effect that may have caused such change in the trading prices or volumes);

• any failure, in and of itself, to meet market revenue or earnings expectations, including revenue or earnings projections or predictions made by the Company (whether or not publicly announced) or securities or financial analysts and any resulting analyst downgrades of the Company’s securities in and of themselves (however, such exception will not apply to any underlying effect that may have caused such failure or such downgrades);

• changes in the Company’s and its subsidiaries’ relationships with employees, customers, distributors, suppliers, vendors, licensors or other business partners as a result of the announcement or pendency of the merger agreement or the anticipated consummation of the merger and the other transactions contemplated by the merger agreement (however, such exception will not apply with respect to the representations and warranties regardingnon-contravention or, solely to the extent related to the representations and warranties regardingnon-contravention, the closing condition regarding accuracy of representations of the Company and Parent’s termination right in the event of any breach of representations and warranties or covenants by the Company);

• any actions taken or failure to take action, in each case, that Parent has expressly approved, consented to or requested in writing; or

• any legal proceeding brought or threatened by a current or former stockholder of the Company against the Company relating to the transactions contemplated by the merger agreement.

90

The first six exceptions listed above will not apply to the extent that such changes disproportionately and adversely affect the Company and its subsidiaries, taken as a whole, as compared to other participants in the industry and the regions of the world in which the Company and its subsidiaries operate.

Definition of Parent Material Adverse Effect

Certain of the representations and warranties made by Parent and Merger Sub are qualified by a materiality or Parent material adverse effect standard. In addition, certain conditions to the performance of the Company’s obligations under the merger agreement are qualified by reference to whether the item in question would have a Parent material adverse effect. For purposes of the merger agreement, a “Parent material adverse effect” means any effect that would, or would reasonably be expected to, prohibit Parent’s or Merger Sub’s ability to consummate the transactions in accordance with the merger agreement and applicable laws. However, the absence of or failure to obtain any consent, approval, waiver or clearance from any governmental entity under antitrust laws with respect to the transactions contemplated under the merger agreement will not constitute a Parent material adverse effect.

• any sale, acquisition, disposition, mortgage, pledge or other transfer of more than 20% of the assets of the Company and its subsidiaries other than in the ordinary course of business; or

• any liquidation or dissolution of the Company, or any extraordinary dividend, whether of cash or other property;

in each case, in any single transaction or series of related transactions and other than the transactions contemplated by the merger agreement or any offer or proposal by Parent or any subsidiary of Parent.

A “superior proposal” means an unsolicited, bona fide written offer submitted after the date of the merger agreement by a person to acquire, directly or indirectly, (i) pursuant to a tender offer, exchange offer, merger, consolidation or other business combination (including by means of a tender offer followed by aback-end merger) beneficial ownership of 50% or more of the outstanding voting securities of the Company or (ii) 50% or more of the assets of the Company, that the board of directors has concluded in its good faith judgment (following consultation with its outside legal counsel and a financial advisor of national standing), taking into account, among other things, all legal, financial, regulatory, timing and other aspects of the offer, including conditions to consummation and the person making the offer, in each case deemed relevant by the board of directors (x) would be, if consummated, more favorable, from a financial point of view, to the Company’s stockholders (in their capacities as stockholders) than the terms of the merger agreement and (y) is reasonably likely to be consummated on the terms proposed (as determined in the good faith judgment of the board of directors).

The Company must as promptly as practicable (and in any event within one business day) notify Parent in writing after actual receipt by the Company and/or any subsidiary (and/or to the knowledge of the Company, by any representative) (excluding employees who are not directors or officers) of any acquisition proposal, any inquiry, indication of interest, proposal or other offer that constitutes, or could reasonably be expected to lead to, an acquisition proposal, or any request fornon-public information (including access to any of the properties, books or records of the Company or any of its subsidiaries) that could reasonably be expected to lead to an acquisition proposal. Such notice is required to describe the material terms and conditions of the acquisition proposal, inquiry, indication of interest, proposal offer or request and the identity of the person submitting such acquisition proposal, inquiry, indication of interest, proposal, offer or request. The Company must keep Parent informed on a reasonably prompt basis (but in no event more than one business day after actual receipt) of the status and material terms of, and material amendments or modifications to, any such acquisition proposal, inquiry, indication of interest, proposal, offer or request and any related material correspondence or communications. The Company must provide Parent as promptly as practicable (and in any event within one business day) with a copy of all written requests, proposals or offers received in connection with any such acquisition proposal. The Company agreed to notify Parent promptly following any meeting of the board of directors at which it has determined to providenon-public information to any person in connection with any such acquisition proposal, inquiry, indication of interest, proposal, offer or request.

The Company must, and must cause its subsidiaries and representatives to, immediately cease any and all existing activities, discussions or negotiations with any persons conducted prior to or on the date of the merger agreement with respect to any acquisition proposal and must direct any person (and such person’s representatives) with which the Company has engaged in any such activities within the12-month period preceding the date of the merger agreement to promptly return or destroy all confidential information previously provided to such person (and such person’s representatives) in accordance with the applicable confidentiality agreement.

Restrictions on Changes of Recommendation to Company Stockholders

Under the merger agreement, the board of directors must submit the merger agreement to the Company’s stockholders for adoption and must recommend that the Company’s stockholders vote in favor of adopting the

98

merger agreement. The merger agreement provides that neither the board of directors, nor any committee thereof, may:

• fail to include the board of directors’ recommendation with respect to the merger agreement in this proxy statement;

• withhold, withdraw, qualify, amend or modify, or publicly propose or resolve to withhold, withdraw, qualify, amend or modify in a manner adverse to Parent or Merger Sub, the board of directors’ recommendation with respect to the merger agreement; or

• adopt, accept, approve, endorse or recommend, or publicly propose to adopt, approve, endorse or recommend, any acquisition proposal (each of the foregoing, referred to as a change of recommendation).

However, nothing in the merger agreement will prevent the board of directors from effecting a change of recommendation in connection with a superior proposal or the Company from terminating the merger agreement to enter into a definitive agreement to accept a superior proposal if:

• the approval of the Company’s stockholders of the adoption of the merger agreement has not yet been obtained;

• the Company has not breached in any material respect its obligations with respect to calling and conducting the special meeting of the Company’s stockholders and has not breached thenon-solicitation and related provisions of the merger agreement;

• a superior proposal has been submitted to the Company, has not been withdrawn and continues to be a superior proposal;

• the Company has given Parent at least four business days’ prior written notice of its intention to take such action along with certain information relating to such superior proposal;

• if requested by Parent, the Company makes its representatives available to discuss and negotiate in good faith with Parent’s representatives any modifications to the terms and conditions of the merger agreement that Parent desires to propose such that such superior proposal would no longer be a superior proposal in comparison to the revised terms of the merger agreement proposed by Parent;

• within such four-business day period, Parent has not made a written, binding and irrevocable offer that the board of directors has concluded in good faith (following consultation with its outside legal counsel and a financial advisor of national standing) to be at least as favorable to the Company’s stockholders as such superior proposal; and

• the board of directors has concluded in good faith (following consultation with its outside legal counsel) that, in light of the superior proposal and any modifications to the merger agreement proposed by Parent, the failure to effect a change of recommendation and terminate the merger agreement would be inconsistent with its fiduciary obligations to the Company’s stockholders under applicable law.

In addition, nothing in the merger agreement will prevent the board of directors from effecting a change of recommendation for a reason unrelated to an acquisition proposal if:

• the approval of the Company’s stockholders of the adoption of the merger agreement has not yet been obtained;

• the Company has not breach in any material respect its obligations with respect to calling and conducting the special meeting of the Company’s stockholders and has not breached thenon-solicitation and related provisions of the merger agreement;

• the board of directors has concluded in good faith (after consultation with its outside legal counsel) that, in light of material facts, events and/or circumstances that as of the date of the merger agreement

99

were unknown by the board of directors and were not reasonably foreseeable by the board of directors as of the date of the merger agreement (referred to as an intervening event) and taking into account the results of any discussions with Parent and any proposed modifications of the merger agreement, as contemplated by the merger agreement, the failure to make a change of recommendation would be inconsistent with its fiduciary obligations to the Company’s stockholders under applicable law (provided that in no event will any of the following, in and of itself, constitute or be deemed an intervening event: (a) any determination by the board of directors that the amount payable by Parent in the merger is not sufficient, (b) the Company exceeding any earnings projections or predictions made by the Company (whether or not publicly announced) or securities or financial analysts and any resulting analyst upgrades of the Company’s securities or any change in the trading price of its common stock, (c) any facts, events or circumstances resulting from any breach of the merger agreement by the Company or (d) the receipt, existence or terms of any acquisition proposal or any matter relating thereto or the consequences thereof);

• the Company has given Parent at least four business days’ prior written notice of its intention to take such action along with certain information relating to such intervening event;

• if requested by Parent, the Company has made its representatives available during such four-business day period to discuss with Parent’s representatives the facts and circumstances underlying such proposed change in recommendation and any modifications to the terms and conditions of the merger agreement that Parent desires to propose that would obviate the need for the board of directors to effect a change of recommendation for an intervening event; and

• if within such four-business day period, Parent has not made a written, binding and irrevocable offer that the board of directors concludes in good faith (after consultation with its outside legal counsel and a financial advisor of national standing) would obviate the need for the board of directors to effect such change of recommendation (with the merger agreement providing that (a) the board of directors must convene a meeting to consider any such offer by Parent promptly following the receipt thereof, (b) the board of directors will not effect a change of recommendation for four business days after receipt by Parent of the notice of an intervening event and (c) any material change in the facts, events or circumstances related to the intervening event will require a new notice of an intervening event to Parent and a newtwo-business day period and discussion process).

In addition, if the board of directors decides to terminate the merger agreement with Parent following receipt of a superior proposal upon the terms summarized above or Parent terminates the merger agreement following a change of recommendation under certain scenarios, the Company must pay the applicable termination fee as described beginning on page [—] under “The Merger Agreement — Termination Fee.”

Additional Agreements of the Parties to the Merger Agreement

Proxy Statement, Stockholders Meeting; Board Recommendation

The Company has agreed to, as promptly as reasonably practicable following the date of the merger agreement, establish a record date for, duly call, give notice of, convene and hold the stockholders’ meeting, which is the special meeting of the Company’s stockholders that is the subject of this proxy statement, to consider and vote upon the adoption of the merger agreement, obtain advisory approval of the compensation that the named executive officers of the Company may receive in the merger and such other matters as agreed to by Parent. The Company will use its reasonable best efforts to solicit from its stockholders proxies in favor of the adoption of the merger agreement and will take all other reasonable action necessary or advisable to obtain such proxies and the required stockholder vote to adopt the merger agreement and to secure the vote of or consent of its stockholders required by and in compliance with the rules and regulations of the Nasdaq Global Select Market, the DGCL and its organizational documents.

The Company may not adjourn or postpone the special meeting of the Company’s stockholders without Parent’s prior written consent, however, the Company may adjourn or postpone the special meeting of the Company’s

100

stockholders (a) to the extent necessary to ensure that any supplement or amendment to this proxy statement that the Company reasonably determines (after consultation with Parent, except with respect to any acquisition proposal or other permitted circumstances) is necessary to comply with applicable laws, is provided to its stockholders in advance of the special meeting of the Company’s stockholders, (b) if, as of the time that the special meeting of the Company’s stockholders is originally scheduled, there are insufficient shares of the Company common stock represented at such meeting to constitute a quorum necessary to conduct the business of the special meeting of the Company’s stockholders, (c) if, as of the time that the special meeting of the Company’s stockholders is originally scheduled, adjournment or postponement of the special meeting of the Company’s stockholders is necessary to enable the Company to solicit additional proxies required to obtain the required stockholder vote to adopt the merger agreement or (d) as necessary to provide for the expiration of any time period required to allow the board of directors to make a change of recommendation in compliance with the merger agreement.

The merger agreement further provides that, prior to the termination of the merger agreement, the Company’s obligations to call, give notice of, or convene the special meeting of the Company’s stockholders, will not be limited by the occurrence of any acquisition proposal, superior proposal or change of recommendation.

Agreements to Use Reasonable Best Efforts

Subject to the terms and conditions of the merger agreement, including with respect to antitrust laws, which are discussed further below, the Company and Parent have agreed to apply for or otherwise seek, and use their respective reasonable best efforts to obtain, all consents and approvals required to be obtained by them for the consummation of the merger and the other transactions contemplated by the merger agreement.

With regard to antitrust laws, subject to the terms and conditions set forth in the merger agreement, the Company and Parent have agreed to make any initial filings required under the HSR Act and any other additional filings required by applicable antitrust laws, including all applicable foreign antitrust approvals set forth in the disclosure schedule that the Company delivered to Parent in connection with the execution of the merger agreement.

Notwithstanding these covenants, Parent and its affiliates are not obligated to:

• litigate or contest any legal proceeding instituted or threatened to be instituted challenging the merger or the other transactions contemplated by the merger agreement as violative of any antitrust law; or

• make proposals, execute or carry out agreements or submit to government orders providing for (a) the sale, license or other disposition or holding separate (through the establishment of a trust or otherwise) of any assets or categories of assets of Parent or the Company or any of their respective affiliates, (b) other than as set forth in the disclosure schedule that the Company delivered to Parent in connection with the execution of the merger agreement, the imposition of any limitation or restriction on the ability of Parent or any of its affiliates to freely conduct their business or, following the closing, the Company’s business or own such assets or (c) the holding separate of the shares of the Company’s capital stock or any limitation or regulation on the ability of Parent or any of its affiliates to exercise full rights of ownership of the shares of the Company’s capital stock, each of which is referred to as an antitrust restraint.

Employee Benefits Matters

Pursuant to the merger agreement, Parent will, or will cause the surviving corporation and its other affiliates to, assume and honor the obligations of the Company and its subsidiaries under the CIC plan and other specified contracts, providing for the payment of severance set forth in accordance with their terms, and to honor all provisions with respect to vesting, accelerated vesting under the CIC plan and any retention agreement and/or payment of any options to purchase shares of Company common stock, RSUs or PRSUs, in each case, unvested

101

as of the effective time of the merger, following the merger and cause all such provisions to apply to payment of the per share merger consideration with respect to such unvested equity awards to the same extent as if the applicable unvested equity awards had been assumed by Parent under the merger agreement, subject in each case to the right to make amendments or modifications to the extent permitted by such terms and subject to any applicable agreements entered into between any employees of the Company and its subsidiaries as of the effective time of the merger (which we refer to as continuing employees).

Except to the extent necessary to avoid the duplication of benefits, Parent will, and will cause the surviving corporation and its other affiliates to, recognize the service of each continuing employee with the Company or its affiliates before the effective time of the merger (to the same extent recognized by the Company or its affiliates immediately prior to the effective time of the merger) as if such service had been performed with Parent or its affiliates under the terms of plans of Parent or any of its affiliates. This recognition of service will apply to eligibility and vesting and level of benefit and benefit accrual under all employee benefit plans or arrangements maintained by Parent or its affiliates (including vacation and severance plans) that such employees may be eligible to participate in after the effective time of the merger, but will not apply for purposes of benefit accrual under a defined benefit plan.

With respect to any welfare plan maintained by Parent or its affiliates in which continuing employees are eligible to participate after the effective time of the merger, Parent will, and will cause the surviving corporation and its other affiliates, to the extent permitted by the relevant welfare plan, and consistent with such plans’ application to similarly situated employees of Parent or its affiliates who are not continuing employees, to waive all limitations as to waiting periods,actively-at-work requirements, evidence of insurability requirements, preexisting conditions and other exclusions with respect to participation and coverage requirements applicable to such employees (and their spouses, domestic partners and dependents) to the extent such conditions and exclusions were satisfied or did not apply to such employees (or their spouses, domestic partners or dependents) under the welfare plans maintained by the Company or its affiliates prior to the effective time of the merger.

The employee benefits matters described in this section apply only with respect to continuing employees (and their dependents and beneficiaries) who are covered under Company employee plans that are maintained primarily for the benefit of employees employed in the United States (including continuing employees regularly employed outside the United States to the extent they participate in such Company employee plans). With respect to continuing employees not described in the preceding sentence, Parent will, and will cause the surviving corporation and its subsidiaries to, comply with all applicable laws, directives and regulations relating to employees and employee benefits matters applicable to such employees.

During the period from the date of the merger agreement and continuing until the earlier of the termination of the merger agreement and the effective time of the merger, the Company will not (i) sponsor or maintain any new Company employee plan or new benefit under existing Company employee plans which was not in effect as of the date of the merger agreement except fornon-material changes made in the ordinary course of business to ERISA- covered health and welfare plans as part of an annual renewal process, (ii) increase its matching contribution formula under the Company 401(k) plan or (iii) increase its percentage of employer cost sharing contribution to Company employee plans in excess of the percentage of cost sharing in effect as of the date of the merger agreement except fornon-material changes to copays and deductibles (but not premiums) for any ERISA-covered health plan as part of an annual renewal process.

The employee benefits provisions contained in the merger agreement and described in this section will be binding upon and inure solely to the benefit of each party to the merger agreement (that is, Parent, Merger Sub and the Company), and nothing in the merger agreement is intended to or will confer upon any other person any right, benefit or remedy of any nature whatsoever. The terms of the merger agreement will not be deemed to (i) establish, amend, or modify any Company benefit plan or any other benefit plan, program, agreement or arrangement maintained or sponsored by Parent, the Company or any subsidiary or any of their respective affiliates, (ii) alter or limit the ability of Parent or any of its subsidiaries (including, after the effective time of the

102

merger, the surviving corporation or any subsidiary of the surviving corporation) to amend, modify or terminate any of the Company employee plans or any other benefit or employment plan, program, agreement or arrangement after the effective time of the merger or (iii) confer upon any current or former employee or other service provider of the Company or its subsidiaries, any right to employment or continued employment or continued service with Parent or any of its subsidiaries (including, following the effective time of the merger, the surviving corporation or any subsidiary of the surviving corporation), or constitute or create an employment or agreement with, or modify theat-will status of any, employee or other service provider.

Indemnification and Insurance

The merger agreement provides that, from and after the effective time of the merger until the sixth anniversary of the effective time of the merger, Parent will assume, and will cause the surviving corporation and its subsidiaries to honor and fulfill in all respects all rights to indemnification by the Company and its subsidiaries to their respective present and former directors and officers pursuant to any indemnification agreements with the Company or such subsidiary made available to Parent and any indemnification or advancement provisions under the Company’s or such subsidiary’s certificate of incorporation or bylaws (or equivalent organizational documents) as in effect on the date of the merger agreement with respect to their acts and omissions as directors and officers of the Company or such subsidiary occurring prior to the effective time, in each case, subject to applicable law.

From the effective time of the merger and ending on the sixth anniversary of the effective time of the merger, the surviving corporation will maintain in effect, and Parent will cause the surviving corporation to maintain in effect, for the benefit of the present and former directors and officers of the Company and its subsidiaries, with respect to their acts and omissions as directors and officers of the Company or any of its subsidiaries occurring prior to the effective time of the merger, the existing policy of directors’ and officers’ liability insurance maintained by the Company or any subsidiary as of the date of the merger agreement in the form made available by the Company to Parent prior to the date of the merger agreement, to the extent that directors’ and officers’ liability insurance coverage is commercially available. However, (a) the surviving corporation may substitute for the existing policy a policy or policies of comparable coverage, including a “tail” or “runoff” insurance policy, (b) the surviving corporation will not be required to pay annual premiums for the existing policy (or for any substitute or “tail” policies) in excess of an amount equal to 300% of the most recently paid annual premium for the existing policy and (c) if requested by Parent, the Company will issue a broker of record letter acceptable to Parent permitting its insurance broker to negotiate and place such “tail” or “runoff” insurance of comparable coverage, Parent will have the right to negotiate such coverage and the Company will reasonably cooperate therewith.

Notwithstanding the foregoing, by giving written notice to Parent at least two business days prior to the effective time of the merger, in lieu of the foregoing insurance, the Company may, at its sole discretion, purchase a comparable “tail” or “runoff” extension to the existing policy for a period of six years after the effective time of the merger for a premium not to exceed an amount equal to 300% of the most recently paid annual premium for the existing policy.

Other Agreements

The merger agreement contains additional agreements of the Company and Parent relating to, among other things:

• Parent’s access to the properties, books, contracts and records of the Company and each of its subsidiaries, data reasonably requested by Parent regarding the Company’s equity incentive awards and related tax compliance information and all other information concerning the business, results of operations, accounting methods, product development efforts, properties (tangible and intangible, including intellectual property) and personnel of the Company or any of its subsidiaries as Parent may

103

reasonably request between the date of the merger agreement and the earlier of the effective time of the merger and the termination of the merger agreement (subject to applicable legal obligations and restrictions);

• stock exchange delisting by the Company;

• Parent participation in legal proceedings brought by current or former stockholders of the Company, the legal proceedings set forth in the disclosure schedule that the Company delivered to Parent in connection with the execution of the merger agreement and legal proceedings by or before any governmental entity that is or is reasonably likely to be material to the Company and its subsidiaries taken as a whole, including any legal proceedings related to anti-corruption laws, export control laws or sanctions;

• confidentiality;

• press releases and other public announcements relating to the merger, the merger agreement, or any of the other transactions contemplated by the merger agreement;

• resignation of directors and officers of the Company; and

• the actions necessary to cause the dispositions of certain common stock and equity-based securities by directors and officers of the Company pursuant to the merger agreement to be exempt under Rule16b-3 promulgated under the Exchange Act.

Further, the Company has agreed to use its commercially reasonable efforts (not to require a concession or expenditure other than immaterial processing or consent fees, or material undertaking) to obtain, prior to the closing, all consents, waivers and approvals required under contracts of the Company or one of its subsidiaries to the extent reasonably requested by Parent. However, any failure to obtain such consents, waivers or approvals will not be considered a breach of covenant for all purposes of the merger agreement.

107

or other obligations contained in the merger agreement, which breach or failure to perform or comply would give rise to the failure to satisfy one of certain conditions to completion of the merger, and, in each such case, (i) any person will have publicly announced an acquisition proposal (or an acquisition proposal will have become publicly known) prior to such termination (unless publicly withdrawn prior to such termination) and (ii) within 12 months of such termination either an acquisition with respect to the Company is consummated or the Company enters into a definitive agreement with respect to an acquisition that is ultimately consummated (even if consummated following such12-month period).

An “acquisition” means any of the following transactions (other than the transactions contemplated under the merger agreement):

• a merger, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction or series of transactions involving the Company pursuant to which the stockholders of the Company immediately preceding such transaction or series of transactions hold less than 50% of the aggregate equity interests in the surviving or resulting entity of such transaction or series of transactions or any direct or indirect parent thereto;

• a sale or other disposition in a transaction or series of transactions by the Company or any of its subsidiaries of assets representing in excess of 50% of the aggregate fair market value of the assets of the Company and its subsidiaries immediately prior to such transaction or series of transactions; or

• the acquisition by any person, directly or indirectly, including by way of a tender offer or exchange offer or issuance by the Company, in a transaction or series of transactions, of beneficial ownership or a right to acquire beneficial ownership of shares representing in excess of 50% of the voting power of the shares of Company common stock outstanding immediately prior to such transaction or series of transactions.

In no event will the Company be required to pay a termination fee on more than one occasion.

If the Company fails to timely pay the termination fee and, in order to obtain the payment, Parent makes a claim that results in a judgment for the amount of the termination fee, the Company will pay to Parent its reasonable costs and expenses (including reasonable attorneys’ fees and expenses) in connection with such suit, together with interest on the amount of the termination fee at the prime rate of Bank of America, N.A. in effect from time to time from the date such payment was required to be made.

Payment of the termination fee (and any additional amounts required pursuant to the preceding paragraph) to Parent by the Company will be the sole and exclusive remedy of Parent and will be deemed to be liquidated damages for any actual or purported breach of the merger agreement and for any and all losses or damages suffered or incurred by Parent or any of its affiliates in connection with the merger agreement (and the termination thereof), the transactions contemplated by the merger agreement (and the abandonment thereof) or any matter forming the basis for such termination and, after such payment has been made, the Company and its affiliates will have no further liability for any such actual or purported breach or for any and all losses or damages suffered or incurred by Parent or any of its affiliates in connection with the merger agreement (and the termination thereof), the transactions contemplated by the merger agreement (and the abandonment thereof) or any matter forming the basis for such termination.

In addition, under the addendum, Parent may be required to pay to the Company a special payment with respect to the termination of the merger agreement under specified circumstances, as described in the section entitled “Other Agreements — Addendum to Master Purchase Agreements” beginning on page [—].

Amendment; Extension; Waiver

Amendment

Subject to applicable law, the parties may amend the merger agreement by executed written agreement, prior to obtaining the approval of the adoption of the merger agreement by holders of Company common stock at the

108

special meeting of the Company’s stockholders, with the approval of the respective boards of directors of the Company and Parent.

Extension; Waiver

At any time prior to the effective time of the merger, each party to the merger agreement may, to the extent legally allowed, (i) extend the time for the performance of any of the obligations or other acts of any other party to the merger agreement, (ii) waive any inaccuracies in the representations and warranties made to such party contained in the merger agreement or in any document delivered pursuant to the merger agreement or (iii) waive compliance with any of the agreements or conditions for the benefit of such party contained in the merger agreement.

Governing Law; Submission to Jurisdiction

The merger agreement is governed by and construed in accordance with the laws of the State of Delaware without giving effect to any choice or conflict of laws, provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of laws of any jurisdictions other than those of the State of Delaware. The parties to the merger agreement irrevocably consented to submit to the exclusive jurisdiction of the Court of Chancery of the State of Delaware, New Castle County, or, if that court does not have jurisdiction, a federal court sitting in Wilmington, Delaware, in respect of the interpretation and enforcement of the provisions of the merger agreement and of the documents referred to in the merger agreement, and in respect of the transactions contemplated by the merger agreement.

Required Vote; Recommendation of the Board of Directors

The approval of this proposal to adopt the merger agreement requires the affirmative vote of the holders of a majority of the shares of Company common stock that are issued and outstanding as of the record date.

The board of directors recommends that you vote “FOR” approval of the proposal to adopt of the merger agreement.

109

OTHER AGREEMENTS

Voting Agreements

On July 8, 2019, concurrently with the execution of the merger agreement, Parent entered into voting agreements with each of Murugesan Shanmugaraj, Benny Mikkelsen, Christian Rasmussen and Mehrdad Givehchi (including certain entities holding shares of Company common stock on their behalf). As of the record date, these stockholders beneficially owned approximately [—]% of the issued and outstanding shares of Company common stock. In connection with the execution and delivery of the voting agreements, Parent did not pay these stockholders any consideration in addition to the consideration they may receive pursuant to the merger agreement in respect of their shares and equity awards. A copy of the form of voting agreement is attached asAnnex C to this proxy statement.

The voting agreements require each of the stockholders, among others things, to vote the subject shares in favor of:

• adoption of the merger agreement; and

• any matter that could reasonably be expected to facilitate the merger (including any adjournment of the special meeting of the stockholders of the Company in order to solicit additional proxies in favor of the adoption of the merger agreement);

and against any acquisition proposal.

In addition, each stockholder subject to a voting agreement granted representatives of Parent an irrevocable proxy to vote the stockholder’s shares of Company common stock in favor of adoption of the merger agreement and against any acquisition proposal.

Each stockholder subject to a voting agreement also agreed not to, directly or indirectly,

• transfer, grant an option with respect to, sell, exchange, pledge or otherwise dispose of, or encumber, its shares of Company common stock;

• enter into a swap or similar transaction that transfers the economic consequences of ownership of its shares of Company common stock; or

• make any offer or enter into any agreement providing for any of the foregoing, other than transfers (a) to any immediate family member, (b) to a trust for the benefit of such stockholder or any immediate family member for estate planning purposes, (c) to a charitable entity; or (d) in connection with or for the purpose of personaltax-planning;provided that in each of the foregoing cases, the transferee agrees to be bound by the voting agreement.

Each stockholder agreed to waive and not to seek any appraisal rights in connection with the merger.

Each voting agreement and all obligations of the stockholders and Parent under each voting agreement will automatically terminate upon the earlier to occur of:

• the first business day following stockholder adoption of the merger agreement; and

• the date and time of the termination of the merger agreement in compliance with its terms.

Addendum to Master Purchase Agreements

In connection with the execution of the merger agreement, on July 8, 2019 the Company, Parent and Cisco International B.V., a wholly owned subsidiary of Parent, also entered into an Addendum to the Master Purchase Agreements by and between such parties, which we refer to as the addendum, pursuant to which Parent and

110

Cisco International B.V. agreed to purchase certain percentages, ranging from 70% to 100% depending on product and date, of Parent’s and Cisco International B.V.’s requirements for certain of the Company’s existing products at agreed upon prices and to negotiate in good faith with respect to Parent’s and Cisco International B.V.’s future purchase of a majority of its requirements for certain of the Company’s future products, subject to certain additional requirements. Parent and Cisco International B.V. may elect to terminate the addendum upon any change in control of the Company or the termination of the merger agreement by (a) the Company in order to accept a superior proposal, (b) Parent because a triggering event has occurred or because the Company breached a representation or warranty contained in the merger agreement or failed to perform any of its covenants or other obligations contained in the merger agreement, which breach or failure to perform or comply would give rise to the failure to satisfy certain conditions to the completion of the merger, or (c) by the Company or Parent because the closing did not occur on or before the end date, in each case at a time that the merger agreement was terminable for the reasons set forth in clauses (a) and (b) above.

In addition, the addendum provides that, subject to certain limitations, Parent will be required to pay the Company a special payment equal to $120 million if the merger agreement is terminated by either Parent or the Company because of any of the following, which we refer to collectively as the special termination conditions:

• the closing did not occur on or before the end date, as it may be extended in accordance with the merger agreement; or

• a governmental entity has issued an order related to antitrust laws having the effect of permanently restraining, enjoining or otherwise prohibiting the merger, which order is final andnon-appealable;

and at the time of such termination, (a) any of the antitrust conditions have not been satisfied or waived by Parent and (b) each of the other conditions to the obligations of Parent and Merger Sub to effect the merger have been satisfied or waived (other than conditions that by their nature are only to be satisfied at the closing of the merger; provided that such conditions were then capable of being satisfied).

However, Parent will not be obligated to pay the special payment if:

• a Company breach of any of its representations, warranties, covenants or agreements under the merger agreement principally caused the failure to satisfy the antitrust conditions; or

• at the time of any termination of the merger agreement in connection with one of the special termination conditions, Parent was entitled to terminate the merger agreement due to the occurrence of a triggering event or due to the Company having breached any of its covenants or other obligations set forth in the merger agreement, or if any representation or warranty of the Company has become inaccurate, in each case such that the closing conditions to the obligations of Parent and Merger Sub regarding the accuracy of representations and warranties and compliance with covenants and other obligations of the Company would not be satisfied.

In no event will Parent be required to pay the special payment on more than one occasion.

If Parent fails to pay the special payment in a timely manner and, in order to obtain such payment, the Company makes a claim that results in a judgment for the amount of the special payment, Parent will pay the Company its reasonable costs and expenses (including reasonable attorneys’ fees and expenses) in connection with such suit, together with interest on the amount of the special payment at the prime rate of Bank of America, N.A. in effect from time to time from the date such payment was required to be made.

Payment of the special payment (and any additional amounts required pursuant to the preceding paragraph) to the Company by Parent will be the sole and exclusive remedy of the Company and will be deemed to be liquidated damages for any actual or purported breach of the merger agreement by Parent or any of its affiliates (including Merger Sub) and for any and all losses or damages suffered or incurred by the Company or any of its affiliates in connection with the addendum and the merger agreement (and the termination thereof), the transactions

111

contemplated by the addendum and the merger agreement (and the abandonment thereof) or any matter forming the basis for such termination and, after such payment has been made, Parent and its affiliates will have no further liability for any such actual or purported breach or for any and all losses or damages suffered or incurred by the Company or any of its affiliates in connection with the addendum or the merger agreement (and the termination thereof), the transactions contemplated by the addendum and the merger agreement (and the abandonment thereof) or any matter forming the basis for such termination.

112

AMENDMENT TO COMPANYBY-LAWS

On July 8, 2019, the board of directors adopted an amendment, which we refer to as theBy-law amendment, to the Company’s Amended and RestatedBy-laws. TheBy-law amendment, which was effective upon adoption by the board of directors, among other things, designates the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have jurisdiction, the United States District Court for the District of Delaware) as the sole and exclusive forum for any action by a stockholder of the Company (in their capacity as such) that is (a) any derivative action or proceeding brought on behalf of the Company, (b) any action asserting a claim of breach of a fiduciary duty owed by any current or former director, officer, other employee, agent or stockholder of the Company to the Company or the Company’s stockholders, including, without limitation, a claim alleging the aiding and abetting of such a breach of fiduciary duty, (c) any action asserting a claim arising pursuant to any provision of the DGCL, the certificate of incorporation or theby-laws of the Company (as each may be amended from time to time), or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware, (d) any action against the Company or any director or officer or other employee of the Company to interpret, apply, enforce or determine the validity of the certificate of incorporation or theby-laws of the Company (as each may be amended from time to time) or (e) any action asserting a claim governed by the internal affairs doctrine or other “internal corporate claim” as that term is defined in Section 115 of the DGCL.

113

NONBINDING ADVISORY PROPOSAL REGARDING COMPENSATION PAYABLE TO OUR NAMED EXECUTIVE OFFICERS IN CONNECTION WITH THE MERGER (PROPOSAL TWO)

In accordance with Section 14A of the Exchange Act and Rule14a-21(c) under the Exchange Act, we are providing stockholders with the opportunity to cast a nonbinding advisory vote with respect to compensation that may be payable to our named executive officers in connection with the merger, as reported on the table on page [—], including the associated narrative discussion.

Accordingly, we are seeking approval of the following resolution at the special meeting:

“RESOLVED, that the compensation that may be paid or become payable to the Company’s named executive officers in connection with the merger, as disclosed in the table in the section of the proxy statement entitled ‘The Merger — Compensation Payable to Named Executive Officers,’ including the associated narrative discussion, is hereby approved.”

The vote on this proposal is a vote separate and apart from the vote on the proposal to adopt the merger agreement and the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies. Accordingly, you may vote “FOR” either or both of the proposal to adopt the merger agreement and the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies and vote “AGAINST” or “ABSTAIN” for this nonbinding advisory proposal regarding compensation that may be payable to our named executive officers in connection with the merger (and vice versa).

Because your vote is advisory, it will not be binding upon the Company, the board of directors, the board of directors’ compensation committee, Parent or any affiliate of Parent. Further, the underlying plans and arrangements are contractual in nature and not, by their terms, subject to stockholder approval. Accordingly, regardless of the outcome of the advisory vote, if the merger agreement is adopted by the stockholders and the merger is completed, such compensation will still be paid to our named executive officers to the extent payable in accordance with the terms of such compensation.

The approval of this proposal requires the affirmative vote of a majority of the votes cast by the holders of all of the shares present or represented at the special meeting and voting on such proposal.

The board of directors recommends that you vote “FOR” approval of the nonbinding advisory proposal regarding compensation that may be payable to our named executive officers in connection with the merger.

114

AUTHORITY TO ADJOURN THE SPECIAL MEETING (PROPOSAL THREE)

If at the special meeting, the board of directors determines it is necessary or appropriate to adjourn the special meeting, to solicit additional proxies to approve the proposal to adopt the merger agreement, then we intend to move to vote on this proposal. If the board of directors determines that it is necessary or appropriate, we will ask our stockholders to vote only on this Proposal Three and not on the proposal to adopt the merger agreement or the nonbinding advisory proposal regarding compensation that may be payable to our named executive officers in connection with the merger.

In this proposal, we are asking our stockholders to approve a proposal to authorize the board of directors, in its discretion, to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies to approve the proposal to adopt the merger agreement. If our stockholders approve the adjournment of the special meeting, we could adjourn the special meeting and any adjourned session of the special meeting and use the additional time to solicit additional proxies, including the solicitation of proxies from stockholders that have previously returned properly executed proxies voting against adoption of the merger agreement. Among other things, approval of this proposal could mean that, even if we had received proxies representing a sufficient number of votes against adoption of the merger agreement such that the proposal to adopt the merger agreement would be defeated, we could adjourn the special meeting without a vote on the adoption of the merger agreement and seek to convince the holders of those shares to change their votes to votes in favor of adoption of the merger agreement.

The vote on this proposal is a vote separate and apart from the vote on the proposal to adopt the merger agreement and the nonbinding advisory proposal regarding compensation that may be payable to our named executive officers in connection with the merger. Accordingly, you may vote “FOR” either or both of the proposal to adopt the merger agreement and the nonbinding advisory proposal regarding compensation that may be payable to our named executive officers in connection with the merger and vote “AGAINST” or “ABSTAIN” for the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies (and vice versa).

The approval of this proposal requires the affirmative vote of a majority of the votes cast by the holders of all of the shares present or represented at the special meeting and voting on such proposal.

The board of directors recommends that you vote “FOR” approval of the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies.

APPRAISAL RIGHTS

If the merger is completed, under Section 262 of the DGCL, holders of record of Company common stock who do not vote in favor of the proposal to adopt the merger agreement, who properly demand appraisal of their shares, who do not withdraw such demand or otherwise waive or lose their right to appraisal and who otherwise comply with the requirements for perfecting and preserving their appraisal rights under Section 262 of the DGCL will be entitled to receive, in lieu of the consideration being offered in the merger, payment in cash for the fair value of their shares of Company common stock (as of the effective time of the merger exclusive of any element of value arising from the accomplishment or expectation of the merger) as determined by the Delaware Court of Chancery in an appraisal proceeding, together with interest to be paid on the amount determined to be fair value, if any, as determined by the Delaware Court of Chancery. These rights are known as appraisal rights. Stockholders electing to exercise appraisal rights must strictly comply with the provisions of Section 262 of the DGCL in order to perfect and preserve their rights.Failure to strictly comply with the procedures specified in Section 262 of the DGCL in a timely and proper manner will result in the loss of appraisal rights under the DGCL.

The following is intended as a brief summary of the law pertaining to appraisal rights under the DGCL. The following, however, is not a complete summary of the law pertaining to appraisal rights under the DGCL and is qualified in its entirety by the full text of Section 262 of the DGCL, which is attached asAnnex D to this proxy statement.

Under Section 262 of the DGCL, when a merger is submitted for adoption at a meeting of stockholders, the corporation must notify each of its stockholders entitled to appraisal rights that appraisal rights are available. A copy of Section 262 of the DGCL must be included with such notice.This proxy statement constitutes the Company’s notice to its stockholders of the availability of appraisal rights in connection with the merger and the full text of Section 262 of the DGCL is attached to this proxy statement asAnnex D.

Stockholders who may wish to exercise their appraisal rights or may wish to preserve their right to do so should review carefully the discussion in this section andAnnex D in its entirety and should consult with their legal advisors, since failure to timely comply with the procedures set forth therein will result in the loss of such rights. A stockholder who loses his, her or its appraisal rights will nonetheless be entitled to receive the $70.00 per share cash merger consideration.

Stockholders wishing to exercise the right to demand appraisal of their shares of Company common stock under Section 262 of the DGCL must satisfy each of the following conditions:

• The stockholder must not vote his, her or its shares of Company common stock in favor of the adoption of the merger agreement.Because a proxy that does not contain voting instructions will, unless revoked, be voted in favor of the adoption of the merger agreement, a stockholder who wishes to exercise appraisal rights must provide instructions in any such proxy to vote against the adoption of the merger agreement or otherwise attend the special meeting and vote against the adoption of the merger agreement, or abstain from voting.

• As more fully described below, the stockholder must deliver to the Company a written demand for appraisal of his, her or its shares of Company common stock before the vote on the adoption of the merger agreement at the special meeting is taken.This written demand for appraisal must be in addition to and separate from any proxy or vote abstaining from or voting against the adoption of the merger agreement. Voting “AGAINST” or failing to vote “FOR” the adoption of the merger agreement by itself does not constitute a demand for appraisal within the meaning of Section 262 of the DGCL.

• The stockholder must hold his, her or its shares of Company common stock, either of record or beneficially, on the date of making the demand for appraisal and must continuously hold such shares from the date of making the demand through the effective date of the merger.

119

• The stockholder (or the surviving corporation in the merger) must file a petition in the Delaware Court of Chancery requesting a determination of the fair value of the shares of Company common stock within 120 days after the effective date of the merger.The surviving corporation of the merger is under no obligation to file any such petition and has no present intention of doing so. Accordingly, it is the obligation of the stockholder to initiate all necessary action to perfect his, her or its appraisal rights in respect of his, her or its shares of Company common stock within the time prescribed in Section 262 of the DGCL.

If you fail to comply with any of these conditions and the merger is completed, you will be entitled to receive the $70.00 per share merger consideration for your shares of Company common stock as provided for in the merger agreement, but you will have no appraisal rights with respect to your shares of Company common stock.

All demands for appraisal must be addressed to our Secretary at Acacia Communications, Inc., Three Mill and Main Place, Suite 400, Maynard, Massachusetts 01754, and must be delivered before the vote on the adoption of the merger agreement is taken at the special meeting, and must be executed by, or on behalf of, the record holder of the shares of Company common stock for which appraisal is demanded.

In addition, the demand must reasonably inform the Company of the identity of the stockholder and that the stockholder intends thereby to demand appraisal of his, her or its shares in connection with the merger. To be effective, a demand for appraisal by a holder of Company common stock must be made by, or in the name of, such registered stockholder, fully and correctly, as the stockholder’s name appears on the stock ledger of the Company and on his, her or its stock certificate(s), if any.

Beneficial owners who do not also hold the shares of record may not directly make appraisal demands to the Company. The beneficial holder must, in such cases, have the registered owner, such as a bank, brokerage firm or other nominee, submit the required demand in respect of those shares.

If the shares are owned of record in a fiduciary capacity, such as by a trustee, guardian or custodian, execution of a demand for appraisal should be made in that capacity. If the shares are owned of record jointly by more than one person, as in a joint tenancy or tenancy in common, the demand must be executed by or on behalf of all joint owners.

An authorized agent, including an authorized agent for two or more joint owners, may execute the demand for appraisal on behalf of a stockholder of record; however, the agent must identify the record owner or owners and expressly disclose the fact that, in executing the demand, he or she is acting as agent for the record owners.

A record holder, such as a bank, brokerage firm or other nominee who holds shares as a nominee for several beneficial owners, may exercise appraisal rights with respect to the shares held for one or more beneficial owners, while not exercising this right for other beneficial owners. In that case, the written demand should state the number of shares as to which appraisal is sought. Where no number of shares is expressly mentioned, the demand will be presumed to cover all shares held in the name of the record owner.If you hold your shares of Company common stock in a bank, a brokerage account or other nominee form and wish to exercise appraisal rights, you should consult with your bank or broker or the other nominee to determine the appropriate procedures for the nominee to make a demand for appraisal. A person having a beneficial interest in shares of Company common stock held of record in the name of another person, such as a bank, brokerage firm or other nominee, must act promptly to cause the record holder to properly follow the steps summarized below and perfect appraisal rights in a timely manner.

Within 10 days after the effective date of the merger, the surviving corporation in the merger will provide notice of the date the merger has become effective to each former stockholder of the Company who has properly demanded an appraisal of their shares of Company common stock under Section 262 of the DGCL and who has not voted in favor of the adoption of the merger agreement. At any time within 60 days after the effective date of

120

the merger, any stockholder who has demanded an appraisal, but who has not commenced an appraisal proceeding or joined that proceeding as a named party, has the right to withdraw the demand and to accept the merger consideration offered pursuant to the merger agreement. Any attempt to withdraw made more than 60 days after the effective date of the merger will require the written approval of the surviving corporation. No appraisal proceeding before the Delaware Court of Chancery as to any stockholder will be dismissed without the approval of the Delaware Court of Chancery, which approval may be conditioned upon any terms the Delaware Court of Chancery deems just; provided, however, that any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party may withdraw its demand for appraisal and accept the merger consideration offered pursuant to the merger agreement within 60 days after the effective date of the merger. If the surviving corporation does not approve a stockholder’s request to withdraw a demand for appraisal when the approval is required or, except with respect to a stockholder that withdraws his, her or its right to appraisal in accordance with the proviso in the immediately preceding sentence, if the Delaware Court of Chancery does not approve the dismissal of an appraisal proceeding, the stockholder would be entitled to receive only the appraised value determined in any such appraisal proceeding. This value could be greater than, less than, or the same as the value of the merger consideration offered pursuant to the merger agreement.

Within 120 days after the effective date of the merger, either the surviving corporation or any stockholder who has complied with the requirements of Section 262 of the DGCL may commence an appraisal proceeding by filing a petition in the Delaware Court of Chancery demanding a determination of the value of the shares held by all stockholders entitled to appraisal. Upon the filing of the petition by a stockholder, service of a copy of such petition shall be made upon the surviving corporation. The surviving corporation has no obligation or present intention to file such a petition in the event there are dissenting stockholders. Accordingly, the failure of a stockholder to file such a petition within the time period and in the manner prescribed in Section 262 of the DGCL could nullify the stockholder’s previously submitted written demand for appraisal.

Within 120 days after the effective date of the merger, any stockholder who has complied with Section 262 of the DGCL, or a beneficial owner of shares held either in a voting trust or by a nominee on behalf of such beneficial owner, shall, upon written request to the surviving corporation, be entitled to receive a written statement setting forth the aggregate number of shares not voted in favor of the merger agreement and with respect to which demands for appraisal rights have been received and the aggregate number of holders of such shares. Such written statement must be mailed to the requesting stockholder within 10 days after such written request is received by the surviving corporation or within 10 days after expiration of the period for delivery of demands for appraisal, whichever is later.

If a petition for appraisal is duly and timely filed by a stockholder, the stockholder must deliver a copy of the petition to the surviving corporation, and the surviving corporation will then be obligated, within 20 days after receiving service of a copy of the petition, to provide the Register in Chancery with a duly verified list containing the names and addresses of all stockholders who have demanded an appraisal of their shares and with whom agreements as to the value of their shares have not been reached by the surviving corporation. The Delaware Court of Chancery is empowered to conduct a hearing upon the petition to determine those stockholders who have complied with Section 262 of the DGCL and who have become entitled to the appraisal rights provided thereby. The Register in Chancery, if so ordered by the Delaware Court of Chancery, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving corporation and to the stockholders shown on such list at the addresses therein stated. The Delaware Court of Chancery may require the stockholders who demanded appraisal of their shares and who hold stock represented by certificates to submit their stock certificates to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings, and if any stockholder fails to comply with such direction, the Delaware Court of Chancery may dismiss the proceedings as to that stockholder. The Delaware Court of Chancery will dismiss the proceedings as to all holders of such shares who are otherwise entitled to appraisal rights unless the total number of shares entitled to appraisal exceeds 1% of the outstanding shares of Company common stock eligible for appraisal or the value of the consideration provided in the merger for such total number of shares exceeds $1 million.

121

After the Delaware Court of Chancery’s determination of the stockholders entitled to appraisal of their shares of Company common stock, an appraisal proceeding shall be conducted in accordance with the rules of the Delaware Court of Chancery, including any rules specifically governing appraisal proceedings. Through this proceeding, the Delaware Court of Chancery will determine the fair value of the shares of Company common stock as of the effective time of the merger exclusive of any element of value arising from the accomplishment or expectation of the merger, together with interest, if any, to be paid upon the amount determined to be the fair value. Unless the Delaware Court of Chancery in its discretion determines otherwise for good cause shown, interest from the effective date of the merger through the date of payment of the judgment shall be compounded quarterly and shall accrue at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the merger and the date of payment of the judgment. When the value is determined, the Delaware Court of Chancery will direct the payment of such fair value, with interest, if any, by the surviving corporation to the stockholders entitled thereto. At any time before the entry of judgment in the proceedings, the surviving corporation may pay to each stockholder entitled to appraisal an amount in cash, in which case interest shall accrue thereafter as provided in Section 262 of the DGCL only upon the sum of (1) the difference, if any, between the amount so paid and the fair value of the shares as determined by the Delaware Court of Chancery, and (2) interest theretofore accrued, unless paid at that time. Upon application by the surviving corporation or by any stockholder entitled to participate in the appraisal proceeding, the Delaware Court of Chancery may, in its discretion, proceed to trial upon the appraisal prior to the final determination of the stockholders entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving corporation pursuant to Section 262 of the DGCL and who has submitted such stockholder’s stock certificates to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under Section 262 of the DGCL.

In determining fair value, the Delaware Court of Chancery is required to take into account all relevant factors. InWeinberger v. UOP, Inc., the Delaware Supreme Court discussed the factors that could be considered in determining fair value in an appraisal proceeding, stating that “proof of value by any techniques or methods which are generally considered acceptable in the financial community and otherwise admissible in court” should be considered and that “[f]air price obviously requires consideration of all relevant factors involving the value of a company.” The Delaware Supreme Court has stated that, in making this determination of fair value, the court must consider market value, asset value, dividends, earnings prospects, the nature of the enterprise and any other factors which could be ascertained as of the date of the merger which throw any light on future prospects of the merged corporation. Section 262 of the DGCL provides that fair value is to be “exclusive of any element of value arising from the accomplishment or expectation of the merger.” InCede & Co. v. Technicolor, Inc., the Delaware Supreme Court stated that such exclusion is a “narrow exclusion [that] does not encompass known elements of value,” but which rather applies only to the speculative elements of value arising from such accomplishment or expectation. InWeinberger, the Delaware Supreme Court construed Section 262 of the DGCL to mean that “elements of future value, including the nature of the enterprise, which are known or susceptible of proof as of the date of the merger and not the product of speculation, may be considered.” An opinion of an investment banking firm as to the fairness from a financial point of view of the consideration payable in a merger is not an opinion as to, and does not in any manner address, fair value under Section 262 of the DGCL. The fair value of their shares as determined under Section 262 of the DGCL could be greater than, the same as, or less than the value of the merger consideration. No representation is made as to the outcome of the appraisal of fair value as determined by the Delaware Court of Chancery. In addition, Delaware courts have decided that the statutory appraisal remedy, depending on factual circumstances, may or may not be a dissenter’s exclusive remedy.You should be aware that the fair value of your shares as determined under Section 262 of the DGCL could be greater than, the same as, or less than the merger consideration that you would otherwise be entitled to receive under the terms of the merger agreement. The Company does not anticipate offering greater than the merger consideration to any stockholder who exercises appraisal rights and reserves the right to assert, in any appraisal proceeding, that, for purposes of Section 262 of the DGCL, the fair value of the Company common stock is less than the merger consideration.

122

Costs of the appraisal proceeding may be imposed upon the surviving corporation and the stockholders participating in the appraisal proceeding by the Delaware Court of Chancery as the Delaware Court of Chancery deems equitable in the circumstances. Upon the application of a stockholder, the Delaware Court of Chancery may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorneys’ fees and the fees and expenses of experts, to be charged pro rata against the value of all shares entitled to appraisal. Any stockholder who has demanded appraisal rights will not, after the effective date of the merger, be entitled to vote such shares for any purpose or to receive payments of dividends or any other distribution with respect to those shares, other than dividends or other distributions payable to stockholders of record at a date prior to the effective date of the merger; however, if no petition for appraisal is filed within 120 days after the effective date of the merger, or if the stockholder delivers a written withdrawal of his, her or its demand for appraisal and an acceptance of the terms of the merger, either within 60 days after the effective date of the merger or thereafter with the written approval of the surviving corporation, then the right of that stockholder to appraisal will cease and that stockholder will be entitled to receive the merger consideration, without interest, for shares of his, her or its Company common stock pursuant to the merger agreement.

In view of the complexity of Section 262 of the DGCL, our stockholders who may wish to dissent from the merger and pursue appraisal rights should consult their legal advisors. To the extent there are any inconsistencies between the foregoing summary and Section 262 of the DGCL, the DGCL shall govern.

123

DELISTING AND DEREGISTRATION OF COMPANY COMMON STOCK

If the merger is consummated, the Company common stock will be delisted from the Nasdaq Global Select Market and deregistered under the Exchange Act and we will no longer file periodic reports with the SEC.

CONDUCT OF OUR BUSINESS IF THE MERGER IS NOT COMPLETED

In the event that the merger agreement is not adopted by our stockholders or if the merger is not completed for

any other reason, our stockholders will not receive any consideration from Parent or Merger Sub for their shares of Company common stock. Instead, we would remain an independent public company, our common stock would continue to be listed and traded on the Nasdaq Global Select Market and our stockholders would continue to be subject to the same risks and opportunities to which they currently are subject with respect to their ownership of Company common stock. If the merger is not completed, there can be no assurance as to the effect of these risks and opportunities on the future value of our shares, including the risk that the market price of Company common stock may decline to the extent that the current market price of our stock reflects a market assumption that the merger will be completed. If the merger is not completed, our business could be disrupted, including our ability to retain and hire key personnel, potential adverse reactions or changes to our business relationships and uncertainty surrounding our future plans and prospects.

Pursuant to the merger agreement, under certain circumstances, we are permitted to terminate the merger agreement and to accept a superior proposal. See “The Merger Agreement — Termination” beginning on page [—].

Pursuant to the merger agreement, under certain circumstances, if the merger is not completed, we may be obligated to pay Parent a termination fee. See “The Merger Agreement — Termination Fee” beginning on page [—]. In addition, under the addendum, Parent may be required to pay to us a special payment with respect to the termination of the merger agreement under specified circumstances, as described in the section entitled “Other Agreements — Addendum to Master Purchase Agreements” beginning on page [—].

124

OTHER MATTERS

Other Matters for Action at the Special Meeting

As of the date of this proxy statement, the board of directors knows of no matters that will be presented for consideration at the special meeting other than as described in this proxy statement.

Future Stockholder Proposals

If the merger is consummated, we will not have public stockholders and there will be no public participation in any future meeting of stockholders of the Company. However, if the merger is not consummated, we expect to hold our 2020 annual meeting of stockholders, which we refer to as the 2020 Annual Meeting, in May 2020, although the Company reserves the right to delay its annual meeting as may be permitted under applicable law. If the merger is not consummated and we hold our 2020 Annual Meeting, the following requirements for stockholder proposals to be brought before the 2020 Annual Meeting and for stockholder proposals to be considered for inclusion in our proxy material for the 2020 Annual Meeting will apply.

Requirements for Stockholder Proposals to be Brought Before the 2020 Annual Meeting

Our amended and restatedby-laws provide that, for nominations of persons for election to the board of directors or other proposals to be considered at an annual meeting of stockholders, a stockholder must give written notice to our Secretary at Three Mill and Main Place, Suite 400, Maynard, Massachusetts 01754, not later than the close of business 90 days, nor earlier than the close of business 120 days, prior to the first anniversary of the date of the preceding year’s annual meeting. However, our amended and restatedby-laws also provide that in the event the date of the annual meeting is more than 30 days before or more than 60 days after such anniversary date, notice must be delivered not later than the close of business on the later of the 90th day prior to such annual meeting or the 10th day following the day on which public announcement of the date of such meeting is first made. Except as noted in this paragraph, to be timely, a notice with respect to the 2020 Annual Meeting must be delivered to the Secretary no earlier than January 17, 2020 and no later than February 16, 2020. Any nomination must include all information relating to the nominee that is required to be disclosed in solicitations of proxies for election of directors in election contests or is otherwise required under Regulation 14A of the Exchange Act, the person’s written consent to be named in the proxy statement and to serve as a director if elected and such information as we might reasonably require to determine the eligibility of the person to serve as a director. As to other business, the notice must include a brief description of the business desired to be brought before the meeting, the reasons for conducting such business at the meeting, and any material interest of such stockholder (and the beneficial owner) in the proposal. The proposal must be a proper subject for stockholder action. In addition, to make a nomination or proposal, the stockholder must be of record at the time the notice is made and must provide certain information regarding itself (and the beneficial owner), including the name and address, as they appear on our books, of the stockholder proposing such business, the number of shares of our capital stock which are, directly or indirectly, owned beneficially or of record by the stockholder proposing such business or its affiliates or associates (as defined in Rule12b-2 promulgated under the Exchange Act) and certain additional information as specified in our amended and restatedby-laws.

Requirements for Stockholder Proposals to be Considered for Inclusion in the Company’s Proxy Materials

Any stockholder who wishes to submit a proposal for inclusion in our proxy materials for the 2020 Annual Meeting must comply with Rule14a-8 promulgated under the Exchange Act. For such proposals to be included in our proxy materials relating to the 2020 Annual Meeting, all applicable requirements of Rule14a-8 must be satisfied and we must receive such proposals no later than December 5, 2019. Such proposals must be delivered to our Secretary, c/o Acacia Communications, Inc., Three Mill and Main Place, Suite 400, Maynard, Massachusetts 01754.

AGREEMENTAND PLANOF MERGER

This AGREEMENT AND PLAN OF MERGER (this “Agreement”) is made and entered into as of July 8, 2019 (the “Agreement Date”), by and among Cisco Systems, Inc., a California corporation (“Parent”), Amarone Acquisition Corp., a Delaware corporation and wholly-owned subsidiary of Parent (“Sub”), and Acacia Communications, Inc., a Delaware corporation (the “Company”).

RECITALS

A. The board of directors of the Company (the “Company Board”) and the boards of directors of Parent and Sub (or duly authorized committees thereof) have determined that it would be advisable to, and in the best interests of, their respective companies and the stockholders of their respective companies that Sub merge with and into the Company (the “Merger”), with the Company to survive the Merger and to become a wholly-owned subsidiary of Parent, on the terms and subject to the conditions set forth in this Agreement, and, in furtherance thereof, have approved and declared advisable this Agreement and the Merger and the other transactions contemplated by this Agreement (collectively, the “Transactions”).

B. Parent, Sub and the Company desire to set forth certain representations, warranties, covenants and other agreements in connection with the Merger as set forth herein.

C. Concurrently with the execution of this Agreement and as a material inducement to the willingness of Parent to enter into this Agreement, certain of the Company’s stockholders are entering into voting agreements and irrevocable proxies in substantially the form attached hereto asExhibit A (each, a “Voting Agreement”), pursuant to which such stockholders have, among other matters, agreed to vote their shares of Company Common Stock in favor of, and otherwise support, the Merger and the other Transactions, each on the terms and subject to the conditions set forth in the Voting Agreement.

D. Concurrently with the execution of this Agreement and as a material inducement to the willingness of Parent to enter into this Agreement, (i) certain employees of the Company are entering into employment agreements and the related Ancillary Agreements (collectively, the “Key Employment Offer Documents”) and (ii) each Key Employee is entering into anon-competition andnon-solicitation agreement, in each case to become effective upon the Closing.

NOW, THEREFORE, in consideration of the representations, warranties, covenants and other agreements contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

ARTICLE I

THE MERGER

TheCash-Out Amount payable pursuant to this Section 1.8(a)(ii) shall be rounded to the nearest cent and computed after aggregatingCash-Out Amounts for all Vested Company Options, Vested Company RSUs or Vested Company PSUs represented by a particular grant held by such Person.

(iii)Unvested Company Options and Unvested Company RSUs. Notwithstanding anything to the contrary herein, Parent will not assume any Unvested Company Option or any Unvested Company RSU. At the Effective Time, by virtue of the Merger and without the need for any further action on the part of the holder thereof, each Unvested Company Option that is unexpired, unexercised and outstanding as of immediately prior to the Effective Time, and each Unvested Company RSU that is unexpired, outstanding and has not yet been settled as of immediately prior to the Effective Time, each subject to and in accordance with Section 1.8(a)(v) and Section 1.9, shall be converted into and represent the right to receive the applicableCash-Out Amount from Parent for such Unvested Company Option or Unvested Company RSU (the “Unvested Cash (Options/RSUs)”).

(v)Payment of Unvested Cash (Options/RSUs) and Unvested Cash (PSUs). The cash payment pursuant to (A) Section 1.8(a)(iii) for Unvested Company Options and Unvested Company RSUs shall be subject to the same restrictions and vesting arrangements (including all provisions with respect to the acceleration of vesting following the Effective Time that would apply if such awards were assumed by Parent pursuant to the Company’s Amended and Restated Severance and Change in Control Benefits Plan (the “CIC Plan”) and/or any retention agreement set forth on Schedule 1.8(a) of the Company Disclosure Letter after giving effect to the applicable Employment Offer Documents) that were applicable to such Unvested Company Options or Unvested Company RSUs, and (B) Section 1.8(a)(iv) in exchange for Unvested Company PSUs shall be subject to the same restrictions and vesting arrangements after giving effect to the applicable Employment Offer Documents that were applicable to such Unvested Company PSUs, in each case as of the Effective Time by virtue of Section 1.8(a)(iii) and Section 1.8(iv) as applicable. Therefore, the Unvested Cash (Options/RSUs) and Unvested Cash (PSUs) shall not be payable by Parent at the Effective Time, and shall instead become payable by Parent on the date that such Unvested Company Options, Unvested Company RSU or Unvested Company PSUs would have become vested under the vesting schedule in place for such awards at the Effective Time (subject to the restrictions and other terms of such vesting

A-11

At the Effective Time, all shares of Company Capital Stock that are owned by the Company as treasury stock immediately prior to the Effective Time, and each share of Company Capital Stock owned by Parent or any direct or indirect wholly-owned Subsidiary of the Company or subsidiary of Parent immediately prior to the Effective Time, shall be cancelled without any conversion thereof.

A-12

the parties hereto the same economic effect as contemplated by this Agreement prior to such stock split, reverse stock split, stock dividend, reorganization, reclassification, combination, recapitalization or other like change.

(e)Appraisal Rights. Notwithstanding anything to the contrary herein, if any stockholder of the Company that is entitled to assert appraisal rights properly demands appraisal rights in accordance with Delaware Law and complies with all conditions and obligations of Section 262 thereof, and such perfected appraisal rights are not effectively withdrawn or lost, each Dissenting Share held by such Dissenting Stockholder shall not be converted at the Effective Time into the right to receive the applicable portion of the consideration payable in the Merger, but shall be entitled only to such rights as are granted by Delaware Law to a holder of Dissenting Shares. The Company shall give Parent (i) prompt notice of any written demand for appraisal received by the Company prior to the Effective Time, withdrawals of such demands and any other instruments served pursuant to Delaware Law and received by the Company that relate to such demands, and (ii) the right to participate in all negotiations and proceedings with respect to such demands under Delaware Law. The Company shall not, except with the prior written consent of Parent, voluntarily make any payment or offer to make any payment with respect to, or settle or offer to settle, any claim or demand in respect of any Dissenting Shares. If, after the Effective Time, any Dissenting Stockholder shall fail to perfect or shall have effectively withdrawn or lost the right to seek appraisal rights, the Dissenting Shares held by such Dissenting Stockholder shall immediately be converted into the right to receive the cash payable pursuant to Section 1.8(a) in respect of such shares as if such shares never had been Dissenting Shares, and Parent shall issue and deliver to the holder thereof at (or as promptly as reasonably practicable after) the applicable time or times specified in Section 1.9(c), following the satisfaction of the applicable conditions set forth in Section 1.9(c), the amount of cash to which such holder would be entitled in respect thereof under Section 1.8(a) as if such shares never had been Dissenting Shares (and all such cash shall be deemed for all purposes of this Agreement to have become deliverable to such holder pursuant to Section 1.8(a)).

(c)Exchange Procedures. Promptly (and in any event within three Business Days) following the Effective Time, Parent shall instruct the Exchange Agent to mail to each holder of record of a certificate or certificates (“Certificates”) that immediately prior to the Effective Time represented outstanding shares of Company Capital Stock, (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Exchange Agent and shall contain such other provisions as Parent may reasonably specify) and (ii) instructions for use of such letter of transmittal in effecting surrender of Certificates in exchange for the cash payable pursuant to Section 1.8(a). Each holder of record of book-entry shares (“Uncertificated Shares”) shall not be required to deliver a Certificate or an executed letter of transmittal to the Exchange Agent to receive the cash payable pursuant to Section 1.8(a). In lieu thereof, each holder of record of one or more Uncertificated Shares may provide an “agent’s message” in customary form with respect to any Uncertificated Share (or such other evidence, if any, of transfer as the Exchange Agent may reasonably request). Upon surrender of a Certificate for cancellation to the Exchange Agent together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may reasonably be required by the Exchange Agent, or upon receipt by the Exchange Agent of an appropriate agent’s message (or such other

(d)No Interest. No interest will be paid or accrued on any cash payable pursuant to Section 1.8(a) or otherwise in connection with the Merger.

(f)No Liability. Notwithstanding anything to the contrary in this Section 1.9, none of the Exchange Agent, the Surviving Corporation or any party hereto shall be liable to any Person for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or similar Applicable Legal Requirement.

(g)Unclaimed Cash.

All cash paid or payable following the surrender for exchange of shares of Company Capital Stock in accordance with this Agreement shall be so paid or payable in full satisfaction of all rights pertaining to such shares of Company Capital Stock, and there shall be no further registration of transfers on the records of the Surviving Corporation of shares of Company Capital Stock that were issued and outstanding immediately prior to the Effective Time. If, after the Effective Time, any Certificate or Uncertificated Shares are presented to the Surviving Corporation for any reason, such Certificate or Uncertificated Shares shall be cancelled and exchanged as provided in this Article I.

1.11.Lost, Stolen or Destroyed Certificates. In the event any Certificate shall have been lost, stolen or destroyed, the Exchange Agent shall issue in exchange for such Certificate, following the making of an affidavit of that fact by the record holder thereof, such cash as may be required pursuant to Section 1.8(a) in respect of such Certificate;provided that Parent or the Exchange Agent may, in its respective reasonable discretion and as a condition precedent to the issuance thereof, require the record holder of such Certificate to deliver a customary bond in such reasonable sum as Parent or the Exchange Agent may reasonably direct as indemnity against any claim that may be made against Parent, the Surviving Corporation, the Exchange Agent and/or any of their respective Representatives with respect to such Certificate.

1.12.Withholding Rights. Parent, the Surviving Corporation, their respective subsidiaries and the Exchange Agent shall be entitled to deduct and withhold from the cash otherwise deliverable under this Agreement and

A-14

from any other payments otherwise required pursuant to this Agreement, to any holder of any shares of Company Capital Stock, any Company Options, any Company RSUs, any Company PSUs, any Certificates or any Uncertificated Shares such amounts as any of Parent, the Surviving Corporation, their respective subsidiaries or the Exchange Agent is required to deduct and withhold with respect to any such deliveries and payments under the Code or any other Applicable Legal Requirements. To the extent that amounts are so withheld and paid over to or credited by the relevant Tax Authority, such withheld amounts shall be treated for all purposes of this Agreement as having been delivered and paid to such holders in respect of which such deduction and withholding was made.

1.13.Tax Consequences. The parties hereto intend the Merger to be a taxable sale of the Company Capital Stock by the Company’s stockholders. Parent makes no representations or warranties to the Company or to any holder of Company Capital Stock, Company Options, Company RSUs or Company PSUs regarding the Tax treatment of the Merger, or any Tax consequences to the Company or any such holder arising in connection with this Agreement, the Merger or any of the other transactions or agreements contemplated by this Agreement.

The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to the feminine and neuter genders of such term. The word “extent” in the phrase “to the extent” shall mean the degree to which a subject or other thing extends, and such phrase shall not mean simply “if.” All references to “days” shall be to calendar days unless otherwise indicated as a “Business Day.”

(c) Unless indicated otherwise, all mathematical calculations contemplated by this Agreement shall be rounded to the tenth decimal place.

(d) The 1.0% threshold established by the parties hereto with respect to the Company’s capitalization in Section 6.3(a) shall not, in and of itself, constitute an economic benchmark for determining whether any Effect shall be deemed to be material in relation to the Company and the Business or shall be deemed to constitute a Material Adverse Effect.

8.4.Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same instrument and shall become effective when one or more counterparts have been signed by each of the parties hereto and delivered to the other parties hereto; it being understood that all parties hereto need not sign the same counterpart.

8.5.Entire Agreement; Parties in Interest. This Agreement and the documents and instruments and other agreements specifically referred to herein or delivered pursuant hereto, including all schedules and exhibits attached hereto, and the Company Disclosure Letter, (i) constitute the entire agreement among the parties hereto with respect to the subject matter hereof and supersede all prior agreements and understandings, both written and oral, among the parties hereto with respect to the subject matter hereof, except for the Confidentiality Agreement, which shall continue in full force and effect, and shall survive any termination of this Agreement, in accordance with its terms, and (ii) are not intended to confer, and shall not be construed as conferring, upon any Person other than the parties hereto any rights or remedies hereunder, except the Indemnified Parties as expressly set forth in Section 5.13.

8.6.Assignment. Neither this Agreement nor any of the rights, interests or obligations under this Agreement may be assigned or delegated, in whole or in part, by operation of law or otherwise by any of the parties hereto without the prior written consent of the other parties hereto, and any such assignment or delegation without such prior written consent shall be null and void, except that Parent may make such assignment or delegation to any direct or indirect wholly-owned subsidiary of Parent without the prior consent of any other party hereto;provided that Parent shall remain liable for all of its obligations under this Agreement. Subject to the preceding sentence, this Agreement shall be binding upon, inure to the benefit of, and be enforceable by, the parties hereto and their respective successors and assigns.

8.7.Severability. In the event that any provision of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement shall continue in full force and effect and shall be interpreted so as reasonably necessary to effect the intent of the parties hereto. The parties hereto shall use all reasonable efforts to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that shall achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision.

8.8.Remedies Cumulative; Specific Performance. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party hereto shall be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party hereto of any one remedy shall not preclude the exercise of any other remedy and nothing in this Agreement shall be deemed a waiver by any party of any right to specific performance or injunctive relief. The parties hereto agree that

A-70

irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties hereto shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof, this being in addition to any other remedy to which they are entitled at law or in equity, and the parties hereto hereby waive the requirement of any posting of a bond in connection with the remedies described herein. Each of the parties agrees that it will not oppose the granting of an injunction, specific performance or other equitable relief on the basis that the other party has an adequate remedy at law or an award of specific performance is not an appropriate remedy for any reason at law or equity.

8.9.Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware without giving effect to any choice or conflict of laws, provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of laws of any jurisdictions other than those of the State of Delaware. The parties hereto hereby irrevocably submit to the exclusive jurisdiction of the Court of Chancery of the State of Delaware, New Castle County, or, if that court does not have jurisdiction, a federal court sitting in Wilmington, Delaware, in respect of the interpretation and enforcement of the provisions of this Agreement and of the documents referred to in this Agreement, and in respect of the Transactions and thereby, and hereby waive, and agree not to assert, as a defense in any Legal Proceeding for the interpretation or enforcement hereof or thereof, that it is not subject thereto or that such Legal Proceeding may not be brought or is not maintainable in said courts or that the venue thereof may not be appropriate or that this Agreement or any such document may not be enforced in or by such courts, and the parties hereto irrevocably agree that all claims with respect to such Legal Proceeding shall be heard and determined in such courts. The parties hereto hereby consent to and grant any such court jurisdiction over the person of such parties and over the subject matter of such dispute and agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 8.2 or in such other manner as may be permitted by Applicable Legal Requirements, shall be valid and sufficient service thereof.

8.10.Rules of Construction. The parties hereto have been represented by counsel during the negotiation, preparation and execution of this Agreement and, therefore, hereby waive, with respect to this Agreement, each Schedule and each Exhibit attached hereto, the application of any Applicable Legal Requirement, holding or rule of construction providing that ambiguities in an agreement or other document shall be construed against the party drafting such agreement or document.

8.11.WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT, OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE ACTIONS OF ANY PARTY HERETO IN NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT HEREOF.

Terms not otherwise defined herein shall have the respective meanings ascribed to them in the Merger Agreement (as defined below).

RECITALS

B. Stockholder understands and acknowledges that the Company and Parent are entitled to rely on (i) the truth and accuracy of Stockholder’s representations contained herein and (ii) Stockholder’s performance of the obligations set forth herein.

NOW, THEREFORE, in consideration of the premises, representations, warranties, covenants and other agreements set forth in the Merger Agreement and herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

1.Restrictions on Shares.

(a) Except for sales of Shares during the period beginning on the date hereof and ending on the fifth Business Day after the date hereof pursuant to the terms of any trading plan adopted pursuant to Rule10b5-1 under the Exchange Act prior to the date of this Agreement, Stockholder shall not at any time prior to the Expiration Date, directly or indirectly, (i) transfer (except as may be specifically required by court order or by operation of law), grant an option with respect to, sell, exchange, pledge or otherwise dispose of, or encumber, the Shares (as such term is defined in Section 4) or any New Shares (as such term is defined in Section 1(d)), (ii) enter into a swap or similar transaction that transfers the economic consequences of ownership of the Shares or any New Shares or (iii) make any offer or enter into any agreement providing for any of the foregoing;provided that nothing contained herein will be deemed to restrict the ability of Stockholder to exercise, prior to the Expiration Date, any Company Options held by Stockholder;provided,further, that Stockholder may transfer Shares and New Shares (A) to any member of Stockholder’s immediate family, (B) to a trust for the benefit of Stockholder or any member of Stockholder’s immediate family for estate planning purposes, (C) to a charitable entity qualified as a 501(c)(3) organization under the Code or (D) in connection with or for the purpose of personaltax-planning;provided,further, that any such transfer shall be permitted only if, as a precondition to such transfer, the transferee agrees in writing to be bound by all of the terms of this Agreement. As used herein, the term “Expiration Date” shall mean the earlier to occur of (x) the first Business Day following the date on which the Company Stockholder Approval shall have been obtained and (y) the date and time of the termination of the Merger Agreement in compliance with its terms.

(b) Except pursuant to the terms of this Agreement, Stockholder shall not, directly or indirectly, grant any proxies or powers of attorney with respect to any of the Shares, deposit any of the Shares into a voting trust, or enter into a voting agreement or similar arrangement or commitment with respect to any of the Shares.

(c) Stockholder shall not, directly or indirectly, take any action that would make any representation or warranty contained herein untrue or incorrect in any material respect or have the effect of materially impairing the ability of Stockholder to perform its obligations under this Agreement or, in its capacity as a stockholder of

A-75

the Company, preventing or materially delaying the consummation of any of the transactions contemplated hereby;provided that to the extent Stockholder is a director or officer of the Company, such Stockholder may, in his or her capacity as a director or officer of the Company, take such actions as may be permitted under Section 5.2 and Section 5.3 of the Merger Agreement.

(d) Any shares of Company Common Stock or other securities of the Company that Stockholder purchases or with respect to which Stockholder otherwise acquires beneficial ownership (as defined in Rule13d-3 under the Exchange Act) after the date of this Agreement and prior to the Expiration Date, including pursuant to the exercise of options or warrants to purchase Shares (collectively, the “New Shares”) shall be subject to the terms and conditions of this Agreement to the same extent as if they constituted Shares.

2.Agreement to Vote Shares. Prior to the Expiration Date, at every meeting of the stockholders of the Company called with respect to any of the following, and at every adjournment or postponement thereof, and on every action or approval by written consent or resolution of the stockholders of the Company with respect to any of the following, Stockholder shall vote, to the extent not voted by the person(s) appointed under the Irrevocable Proxy (as defined in Section 3) the Shares and any New Shares in favor of adoption of the Merger Agreement and any matter that would reasonably be expected to facilitate the Merger (including any adjournment of any meeting of the stockholders of the Company in order to solicit additional proxies in favor of the adoption of the Merger Agreement) and against any Acquisition Proposal and any other matter that would reasonably be expected to impede, interfere with, delay, postpone or adversely affect the Merger or any of the transactions contemplated by the Merger Agreement in any material respect. Parent acknowledges that the voting covenant, set forth herein and in the Irrevocable Proxy shall not be effective for any other purpose and Stockholder retains the right to vote in any manner on all other matters in Stockholder’s sole discretion.

3.Irrevocable Proxy. Concurrently with the execution and delivery of this Agreement, Stockholder shall deliver to Parent a duly executed proxy in the form attached hereto asExhibit A (the “Irrevocable Proxy”), which proxy is coupled with an interest, and, until the Expiration Date, shall be irrevocable to the fullest extent permitted by law, with respect to each and every meeting of the stockholders of the Company or action or approval by written resolution or consent of stockholders of the Company with respect to the matters contemplated by Section 2 covering the total number of Shares and New Shares in respect of which Stockholder is entitled to vote at any such meeting or in connection with any such written consent. Upon the execution of this Agreement by Stockholder, (i) Stockholder hereby revokes any and all prior proxies (other than the Irrevocable Proxy) given by Stockholder with respect to the subject matter contemplated by Section 2 and (ii) Stockholder shall not grant any subsequent proxies with respect to such subject matter, or enter into any agreement or understanding with any Person to vote or give instructions with respect to the Shares and any New Shares in any manner inconsistent with the terms of Section 2, until after the Expiration Date.

4.Representations, Warranties and Covenants of Stockholder. Stockholder hereby represents, warrants and covenants to Parent as follows:

(a) Stockholder is the beneficial or record owner of, or exercises voting power over, that number of shares of Company Common Stock set forth on the signature page hereto (all such shares owned beneficially or of record by Stockholder, or over which Stockholder exercises voting power, on the date hereof, collectively, the “Shares”). Stockholder does not hold any other outstanding shares of capital stock of the Company. No person not a signatory to this Agreement has a beneficial interest in or a right to acquire or vote any of the Shares (other than, (i) if Stockholder is a partnership, the rights and interest of persons and entities that own partnership interests in Stockholder under the partnership agreement governing Stockholder and applicable partnership law or (ii) if Stockholder is a married individual and resides in a State with community property laws, the community property interest of his or her spouse to the extent applicable under such community property law, in which case such spouse has executed a spousal consent hereto if requested by Parent). The Shares are and will be at all times up until the Expiration Date free and clear of any security interests, liens, claims, pledges, options, rights of first refusal,co-sale rights, agreements, limitations on Stockholder’s voting rights, charges and other encumbrances of

A-76

any nature that would materially and adversely affect the ability of Stockholder to perform his, her or its obligations under this Agreement. Stockholder’s principal residence or place of business is set forth on the signature page hereto.

(b) Stockholder has all requisite power, capacity and authority to enter into this Agreement and to consummate the transactions contemplated hereby. The execution and delivery of this Agreement by Stockholder and the consummation by Stockholder of the transactions contemplated hereby have been duly authorized by all necessary action, if any, on the part of Stockholder. This Agreement has been duly executed and delivered by Stockholder and, assuming the due authorization, execution and delivery of this Agreement by Parent, constitutes a valid and binding obligation of Stockholder, enforceable against Stockholder in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and remedies generally and to general principles of equity.

(c) The execution and delivery of this Agreement does not, and the consummation of the transactions contemplated hereby and compliance with the provisions hereof will not, conflict with, result in a breach or violation of or default (with or without notice or lapse of time or both) under, or require notice to or the consent of any person under, any agreement, law, rule, regulation, judgment, order or decree by which Stockholder is bound, except for such conflicts, breaches, violations or defaults that would not, individually or in the aggregate, prevent or materially delay Stockholder from performing his, her or its obligations under this Agreement.

5.Consent and Waiver. Stockholder hereby waives any and all rights to contest or object to the execution and delivery of the Merger Agreement, the Company Board of Directors’ actions in approving and recommending the Merger, the consummation of the Merger and the other transactions provided for in the Merger Agreement, or to seek damages or other legal or equitable relief in connection therewith (but for the avoidance of doubt this waiver does not extend to any claims relating to any breach of the Merger Agreement). From and after the Effective Time, Stockholder’s right to receive cash on the terms and subject to the conditions set forth in the Merger Agreement shall constitute Stockholder’s sole and exclusive right against the Company and/or Parent in respect of Stockholder’s ownership of the Shares or status as a stockholder of the Company or any agreement or instrument with the Company pertaining to the Shares or Stockholder’s status as a stockholder of the Company.

6.Confidentiality. Stockholder (i) shall hold any information regarding this Agreement, the Merger Agreement and the Merger in strict confidence, and shall not divulge any such information to any third person until Parent has publicly disclosed the Merger and this Agreement and (ii) shall not issue or cause the publication of any press release or other public announcement with respect to this Agreement, the Merger, the Merger Agreement or the other transactions contemplated thereby without the prior written consent of Parent, except, in case (i) or (ii), as may be required by law or by any listing agreement with, or the policies of, the NASDAQ Global Select Market in which circumstance Stockholder shall make reasonable efforts to consult with Parent to the extent practicable.

7.Appraisal Rights. Stockholder agrees not to exercise any rights of appraisal or any dissenters’ rights that Stockholder may have (whether under applicable law or otherwise) or could potentially have or acquire in connection with the Merger.

8.Miscellaneous.

(a) Notices. All notices and other communications hereunder shall be in writing and shall be deemed given on (i) the date of delivery, if delivered personally, by commercial delivery service or mailed by registered or certified mail (return receipt requested) or (ii) on the date of confirmation of receipt (or the next Business Day, if the date of confirmation of receipt is not a Business Day), if sent via facsimile ore-mail (with confirmation of

This Agreement, together with any rights, interests or obligations of Parent hereunder, may be assigned or delegated in whole or in part by Parent to any affiliate of Parent to which Parent assigns its rights under the Merger Agreement without the consent of or any action by Stockholder upon notice by Parent to Stockholder as herein provided. Subject to the preceding sentence, this Agreement shall be binding upon, inure to the benefit of, and be enforceable by, the parties hereto and their respective permitted successors and assigns (including any person to whom any Shares are sold, transferred or assigned).

(f)Severability. In the event that any provision of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement shall continue in full force and effect and the application of such provision to other persons or circumstances shall be interpreted so as reasonably to effect the intent of the parties hereto. The parties hereto further agree to use their commercially reasonable efforts to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that shall achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision.

(g)Remedies Cumulative. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party shall be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy shall not preclude the exercise of any other remedy.

(h)Governing Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of Delaware without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of laws of any jurisdictions other than those of the State of Delaware. The parties hereto hereby irrevocably submit to the exclusive jurisdiction the Court of Chancery of the State of Delaware, New Castle County, or, if that court does not have jurisdiction, a federal court sitting in Wilmington, Delaware, solely in respect of the interpretation and enforcement of the provisions of this Agreement and of the documents referred to in this Agreement, and in respect of the transactions contemplated hereby and thereby, and hereby waive, and agree not to assert, as a defense in any action, suit or proceeding for the interpretation or enforcement hereof or thereof, that it is not subject thereto or that such action, suit or proceeding may not be brought or is not maintainable in said courts or that the venue thereof may not be appropriate or that this Agreement or any such document may not be enforced in or by such courts, and the parties hereto irrevocably agree that all claims with respect to such action or proceeding shall be heard and determined in such a Delaware state or federal court. The parties hereby consent to and grant any such court jurisdiction over the person of such parties and over the subject matter of such dispute and agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 8(a) or in such other manner as may be permitted by applicable law, shall be valid and sufficient service thereof.

A-79

each of the Company and Parent may rely upon such delivery as conclusively evidencing the consents and waivers of Stockholder referred to in Section 5, in each case for purposes of all agreements and instruments to which such elections, consents and/or waivers are applicable or relevant.

(k)WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT, OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE ACTIONS OF ANY PARTY HERETO IN NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT HEREOF.

A-88

ARTICLE VIII

The Corporation shall provide indemnification as follows:

1.Actions, Suits and Proceedings Other than by or in the Right of the Corporation. The Corporation shall indemnify each person who was or is a party or threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that he or she is or was, or has agreed to become, a director or officer of the corporation, or is or was serving, or has agreed to serve, at the request of the corporation, as a director, officer, partner, employee or trustee of, or in a similar capacity with, another corporation, partnership, joint venture, trust or other enterprise (including any employee benefit plan) (all such persons being referred to hereafter as an “Indemnitee”), or by reason of any action alleged to have been taken or omitted in such capacity, against all expenses (including attorneys’ fees), liabilities, losses, judgments, fines (including excise taxes and penalties arising under the Employee Retirement Income Security Act of 1974), and amounts paid in settlement actually and reasonably incurred by or on behalf of Indemnitee in connection with such action, suit or proceeding and any appeal therefrom, if Indemnitee acted in good faith and in a manner which Indemnitee reasonably believed to be in, or not opposed to, the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that Indemnitee did not act in good faith and in a manner which Indemnitee reasonably believed to be in, or not opposed to, the best interests of the corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his or her conduct was unlawful.

2.Actions or Suits by or in the Right of the Corporation. The Corporation shall indemnify any Indemnitee who was or is a party to or threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that Indemnitee is or was, or has agreed to become, a director or officer of the corporation, or is or was serving, or has agreed to serve, at the request of the corporation, as a director, officer, partner, employee or trustee of, or in a similar capacity with, another corporation, partnership, joint venture, trust or other enterprise (including any employee benefit plan), or by reason of any action alleged to have been taken or omitted in such capacity, against all expenses (including attorneys’ fees) and, to the extent permitted by law, amounts paid in settlement actually and reasonably incurred by or on behalf of Indemnitee in connection with such action, suit or proceeding and any appeal therefrom, if Indemnitee acted in good faith and in a manner which Indemnitee reasonably believed to be in, or not opposed to, the best interests of the corporation, except that no indemnification shall be made under this Section 2 in respect of any claim, issue or matter as to which Indemnitee shall have been adjudged to be liable to the corporation, unless, and only to the extent, that the Court of Chancery of Delaware or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of such liability but in view of all the circumstances of the case, Indemnitee is fairly and reasonably entitled to indemnity for such expenses (including attorneys’ fees) which the Court of Chancery of Delaware or such other court shall deem proper.

3.Indemnification for Expenses of Successful Party. Notwithstanding any other provisions of this Article VIII, to the extent that an Indemnitee has been successful, on the merits or otherwise, in defense of any action, suit or proceeding referred to in Sections 1 and 2 of this Article VIII, or in defense of any claim, issue or matter therein, or on appeal from any such action, suit or proceeding, Indemnitee shall be indemnified against all expenses (including attorneys’ fees) actually and reasonably incurred by or on behalf of Indemnitee in connection therewith.

4.Notification and Defense of Claim. As a condition precedent to an Indemnitee’s right to be indemnified under this Article VIII, such Indemnitee must notify the corporation in writing as soon as reasonably practicable of any action, suit, proceeding or investigation involving such Indemnitee for which indemnity will or could be

A-89

sought. With respect to any action, suit, proceeding or investigation of which the corporation is so notified, the corporation will be entitled to participate therein at its own expense and/or to assume the defense thereof at its own expense, with legal counsel reasonably acceptable to Indemnitee. After notice from the corporation to Indemnitee of its election so to assume such defense, the corporation shall not be liable to Indemnitee for any legal or other expenses subsequently incurred by Indemnitee in connection with such action, suit, proceeding or investigation, other than as provided below in this Section 4. Indemnitee shall have the right to employ his or her own counsel in connection with such action, suit, proceeding or investigation, but the fees and expenses of such counsel incurred after notice from the corporation of its assumption of the defense thereof shall be at the expense of Indemnitee unless (i) the employment of counsel by Indemnitee has been authorized by the corporation, (ii) counsel to Indemnitee shall have reasonably concluded that there may be a conflict of interest or position on any significant issue between the corporation and Indemnitee in the conduct of the defense of such action, suit, proceeding or investigation or (iii) the corporation shall not in fact have employed counsel to assume the defense of such action, suit, proceeding or investigation, in each of which cases the fees and expenses of counsel for Indemnitee shall be at the expense of the corporation, except as otherwise expressly provided by this Article VIII. The Corporation shall not be entitled, without the consent of Indemnitee, to assume the defense of any claim brought by or in the right of the corporation or as to which counsel for Indemnitee shall have reasonably made the conclusion provided for in clause (ii) above. The Corporation shall not be required to indemnify Indemnitee under this Article VIII for any amounts paid in settlement of any action, suit, proceeding or investigation effected without its written consent. The Corporation shall not settle any action, suit, proceeding or investigation in any manner which would impose any penalty or limitation on Indemnitee without Indemnitee’s written consent. Neither the corporation nor Indemnitee will unreasonably withhold or delay its consent to any proposed settlement.

5.Advance of Expenses. Subject to the provisions of Section 6 of this Article VIII, in the event of any threatened or pending action, suit, proceeding or investigation of which the corporation receives notice under this Article VIII, any expenses (including attorneys’ fees) incurred by or on behalf of Indemnitee in defending an action, suit, proceeding or investigation or any appeal therefrom shall be paid by the corporation in advance of the final disposition of such matter; provided, however, that the payment of such expenses incurred by or on behalf of Indemnitee in advance of the final disposition of such matter shall be made only upon receipt of an undertaking by or on behalf of Indemnitee to repay all amounts so advanced in the event that it shall ultimately be determined that Indemnitee is not entitled to be indemnified by the corporation as authorized in this Article VIII; and provided further that no such advancement of expenses shall be made under this Article VIII if it is determined (in the manner described in Section 6) that (i) Indemnitee did not act in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, or (ii) with respect to any criminal action or proceeding, Indemnitee had reasonable cause to believe his or her conduct was unlawful. Such undertaking shall be accepted without reference to the financial ability of Indemnitee to make such repayment.

6.Procedure for Indemnification and Advancement of Expenses. In order to obtain indemnification or advancement of expenses pursuant to Section 1, 2, 3 or 5 of this Article VIII, an Indemnitee shall submit to the corporation a written request. Any such advancement of expenses shall be made promptly, and in any event within 60 days after receipt by the corporation of the written request of Indemnitee, unless (i) the corporation has assumed the defense pursuant to Section 4 of this Article VIII (and none of the circumstances described in Section 4 of this Article VIII that would nonetheless entitle the Indemnitee to indemnification for the fees and expenses of separate counsel have occurred) or (ii) the corporation determines within such60-day period that Indemnitee did not meet the applicable standard of conduct set forth in Section 1, 2 or 5 of this Article VIII, as the case may be. Any such indemnification, unless ordered by a court, shall be made with respect to requests under Section 1 or 2 only as authorized in the specific case upon a determination by the corporation that the indemnification of Indemnitee is proper because Indemnitee has met the applicable standard of conduct set forth in Section 1 or 2, as the case may be. Such determination shall be made in each instance (a) by a majority vote of the directors of the corporation consisting of persons who are not at that time parties to the action, suit or proceeding in question (“disinterested directors”), whether or not a quorum, (b) by a committee of disinterested

A-90

directors designated by majority vote of disinterested directors, whether or not a quorum, (c) if there are no disinterested directors, or if the disinterested directors so direct, by independent legal counsel (who may, to the extent permitted by law, be regular legal counsel to the corporation) in a written opinion, or (d) by the stockholders of the corporation.

7.Remedies. The right to indemnification or advancement of expenses as granted by this Article VIII shall be enforceable by Indemnitee in any court of competent jurisdiction. Neither the failure of the corporation to have made a determination prior to the commencement of such action that indemnification is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor an actual determination by the corporation pursuant to Section 6 of this Article VIII that Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that Indemnitee has not met the applicable standard of conduct. Indemnitee’s expenses (including attorneys’ fees) reasonably incurred in connection with successfully establishing Indemnitee’s right to indemnification, in whole or in part, in any such proceeding shall also be indemnified by the corporation. Notwithstanding the foregoing, in any suit brought by Indemnitee to enforce a right to indemnification hereunder it shall be a defense that the Indemnitee has not met any applicable standard for indemnification set forth in the General Corporation Law of the State of Delaware.

8.Limitations. Notwithstanding anything to the contrary in this Article VIII, except as set forth in Section 7 of this Article VIII, the corporation shall not indemnify an Indemnitee pursuant to this Article VIII in connection with a proceeding (or part thereof) initiated by such Indemnitee unless the initiation thereof was approved by the Board of Directors of the corporation. Notwithstanding anything to the contrary in this Article VIII, the corporation shall not indemnify an Indemnitee to the extent such Indemnitee is reimbursed from the proceeds of insurance, and in the event the corporation makes any indemnification payments to an Indemnitee and such Indemnitee is subsequently reimbursed from the proceeds of insurance, such Indemnitee shall promptly refund indemnification payments to the corporation to the extent of such insurance reimbursement.

9.Subsequent Amendment. No amendment, termination or repeal of this Article VIII or of the relevant provisions of the General Corporation Law of the State of Delaware or any other applicable laws shall adversely affect or diminish in any way the rights of any Indemnitee to indemnification under the provisions hereof with respect to any action, suit, proceeding or investigation arising out of or relating to any actions, transactions or facts occurring prior to the final adoption of such amendment, termination or repeal.

10.Other Rights. The indemnification and advancement of expenses provided by this Article VIII shall not be deemed exclusive of any other rights to which an Indemnitee seeking indemnification or advancement of expenses may be entitled under any law (common or statutory), agreement or vote of stockholders or disinterested directors or otherwise, both as to action in Indemnitee’s official capacity and as to action in any other capacity while holding office for the corporation, and shall continue as to an Indemnitee who has ceased to be a director or officer, and shall inure to the benefit of the estate, heirs, executors and administrators of Indemnitee. Nothing contained in this Article VIII shall be deemed to prohibit, and the corporation is specifically authorized to enter into, agreements with officers and directors providing indemnification and advancement of expenses rights and procedures different from, equivalent to, or greater or less than, those set forth in this Article VIII, and this Article VIII shall not be deemed to limit, modify or condition the rights contained in any such agreement or modify or supplement the procedures contained in any such agreement in any manner that may be adverse to such officers or directors. In addition, the corporation may, to the extent authorized from time to time by its Board of Directors, grant indemnification rights to other employees or agents of the corporation or other persons serving the corporation and such rights may be equivalent to, or greater or less than, those set forth in this Article VIII.

11.Partial Indemnification. If an Indemnitee is entitled under any provision of this Article VIII to indemnification by the corporation for some or a portion of the expenses (including attorneys’ fees), liabilities, losses, judgments, fines (including excise taxes and penalties arising under the Employee Retirement Income Security Act of 1974) or amounts paid in settlement actually and reasonably incurred by or on behalf of

A-91

Indemnitee in connection with any action, suit, proceeding or investigation and any appeal therefrom but not, however, for the total amount thereof, the corporation shall nevertheless indemnify Indemnitee for the portion of such expenses (including attorneys’ fees), liabilities, losses, judgments, fines (including excise taxes and penalties arising under the Employee Retirement Income Security Act of 1974) or amounts paid in settlement to which Indemnitee is entitled.

12.Insurance. The Corporation may purchase and maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the corporation or another corporation, partnership, joint venture, trust or other enterprise (including any employee benefit plan) against any expense, liability or loss incurred by him or her in any such capacity, or arising out of his or her status as such, whether or not the corporation would have the power to indemnify such person against such expense, liability or loss under the General Corporation Law of the State of Delaware.

13.Savings Clause. If this Article VIII or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the corporation shall nevertheless indemnify each Indemnitee as to any expenses (including attorneys’ fees), liabilities, losses, judgments, fines (including excise taxes and penalties arising under the Employee Retirement Income Security Act of 1974) and amounts paid in settlement in connection with any action, suit, proceeding or investigation, whether civil, criminal or administrative, including an action by or in the right of the corporation, to the fullest extent permitted by any applicable portion of this Article VIII that shall not have been invalidated and to the fullest extent permitted by applicable law.

14.Definitions. Terms used herein and defined in Section 145(h) and Section 145(i) of the General Corporation Law of the State of Delaware shall have the respective meanings assigned to such terms in such Section 145(h) and Section 145(i).

Section 1.4:     Adjournments.

The chair shall have the power to adjourn the meeting to another time, date and place (if any). Any meeting of stockholders may adjourn from time to time, and notice need not be given of any such adjourned meeting if the time, date and place (if any) thereof are announced at the meeting at which the adjournment is taken;provided,however, that if the adjournment is for more than thirty (30) days, or if after the adjournment a new record date is fixed for the adjourned meeting, then a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting.

If a quorum shall fail to attend any meeting, the chairperson of the meeting or the holders of a majority of the shares entitled to vote who are present, in person or by proxy, at the meeting may adjourn the meeting. Shares of the Corporation’s stock belonging to the Corporation (or to another corporation, if a majority of the shares entitled to vote in the election of directors of such other corporation are held, directly or indirectly, by the Corporation), shall neither be entitled to vote nor be counted for quorum purposes;provided,however, that the foregoing shall not limit the right of the Corporation or any other corporation to vote any shares of the Corporation’s stock held by it in a fiduciary capacity and to count such shares for purposes of determining a quorum.

A-93

Section 1.6:     Organization. Meetings of stockholders shall be presided over by such person as the Board of Directors may designate, or, in the absence of such a person, the Chairperson of the Board of Directors, or, in the absence of such person, the President of the Corporation, or, in the absence of such person, such person as may be chosen by the holders of a majority of the shares entitled to vote who are present, in person or by proxy, at the meeting.

Such a proxy may be prepared, transmitted and delivered in any manner permitted by applicable law. Voting at meetings of stockholders need not be by written ballot unless such is demanded at the meeting before voting begins by a stockholder or stockholders holding shares representing at least one percent (1%) of the votes entitled to vote at such meeting, or by such stockholder’s or stockholders’ proxy;provided,however, that an election of directors shall be by written ballot if demand is so made by any stockholder at the meeting before voting begins. If a vote is to be taken by written ballot, then each such ballot shall state the name of the stockholder or proxy voting and such other information as the chairperson of the meeting deems appropriate and, if authorized by the Board of Directors, the ballot may be submitted by electronic transmission in the manner provided by law. Directors shall be elected by a plurality of the votes of the shares present in person or represented by proxy at the meeting and entitled to vote on the election of directors. Unless otherwise provided by applicable law, the Certificate of Incorporation or these Bylaws, every matter other than the election of directors shall be decided by the affirmative vote of the holders of a majority of the shares of stock entitled to vote thereon that are present in person or represented by proxy at the meeting and are voted for or against the matter.

Section 1.8:     Fixing Date for Determination of Stockholders of Record.

If no record date is fixed by the Board of Directors, then the record date shall be as provided by applicable law. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting;provided,however, that the Board of Directors may fix a new record date for the adjourned meeting.

Section 1.9:     List of Stockholders Entitled to Vote.

If the meeting is held at a place, the list shall also be produced and kept at the time and place of the meeting during the whole time thereof and may be inspected by any stockholder who is present at the meeting.

Section 1.10:     Action by Written Consent of Stockholders.

(a)Procedure. Unless otherwise provided by the Certificate of Incorporation, any action required or permitted to be taken at any annual or special meeting of the stockholders may be taken without a meeting, without prior notice and without a vote, if a consent or consents are in writing, setting forth the action so taken, shall be signed in the manner permitted by law by the holders of outstanding stock having not less than the number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted. Written stockholder consents shall bear the date of signature of each stockholder who signs the consent in the manner permitted by law and shall be delivered to the Corporation as provided in subsection (b) below. No written consent shall be effective to take the action set forth therein unless, within sixty (60) days of the earliest dated consent delivered to the Corporation in the manner provided above, written consents signed by a sufficient number of stockholders to take the action set forth therein are delivered to the Corporation in the manner provided above.

(b) A telegram, cablegram or other electronic transmission consenting to an action to be taken and transmitted by a stockholder or proxyholder, or a person or persons authorized to act for a stockholder or proxyholder, shall be deemed to be written, signed and dated for the purposes of this section, provided that any such telegram, cablegram or other electronic transmission sets forth or is delivered with information from which the Corporation can determine (i) that the telegram, cablegram or other electronic transmission was transmitted by the stockholder or proxyholder or by a person or persons authorized to act for the stockholder or proxyholder and (ii) the date on which such stockholder or proxyholder or authorized person or persons transmitted such telegram, cablegram or electronic transmission. The date on which such telegram, cablegram or electronic transmission is transmitted shall be deemed to be the date on which such consent was signed. No consent given by telegram, cablegram or other electronic transmission shall be deemed to have been delivered until such consent is reproduced in paper form and until such paper form shall be delivered to the Corporation by delivery to its registered office in the State of Delaware, its principal place of business or an officer or agent of the Corporation having custody of the book in which proceedings of meetings of stockholders are recorded. Delivery made to a Corporation’s registered office shall be made by hand or by certified or registered mail, return receipt requested. Notwithstanding the foregoing limitations on delivery, consents given by telegram, cablegram or other electronic transmission may be otherwise delivered to the principal place of business of the Corporation or to an officer or agent of the Corporation having custody of the book in which proceedings of meetings of stockholders are recorded if, to the extent and in the manner provided by resolution of the Board of Directors of the Corporation.

(c)Notice of Consent. Prompt notice of the taking of corporate action by stockholders without a meeting by less than unanimous written consent of the stockholders shall be given to those stockholders who have not consented thereto in writing and, who, if the action had been taken at a meeting, would have been entitled to notice of the meeting, if the record date for such meeting had been the date that written consents signed by a sufficient number of holders to take the action were delivered to the Corporation as required by law. In the case of a Certificate of Action (as defined below), if the Delaware General Corporation Law so requires, such notice shall be given prior to filing of the certificate in question. If the action which is consented to requires the filing of a certificate under the Delaware General Corporation Law (the “Certificate of Action”), then if the Delaware General Corporation Law so requires, the certificate so filed shall state that written stockholder consent has been given in accordance with Section 228 of the Delaware General Corporation Law and that written notice of the taking of corporate action by stockholders without a meeting as described herein has been given as provided in such section.

Section 1.11:     Inspectors of Elections.

(a)Applicability. Unless otherwise provided in the Corporation’s Certificate of Incorporation or required by the Delaware General Corporation Law, the following provisions of this Section 1.11 shall apply only if and when the Corporation has a class of voting stock that is: (i) listed on a national securities exchange;

A-95

(ii) authorized for quotation on an automated interdealer quotation system of a registered national securities association; or (iii) held of record by more than two thousand (2,000) stockholders. In all other cases, observance of the provisions of this Section 1.11 shall be optional, and at the discretion of the Board of Directors of the Corporation.

(b)Appointment. The Corporation shall, in advance of any meeting of stockholders, appoint one or more inspectors of election to act at the meeting and make a written report thereof. The Corporation may designate one or more persons as alternate inspectors to replace any inspector who fails to act. If no inspector or alternate is able to act at a meeting of stockholders, the person presiding at the meeting shall appoint one or more inspectors to act at the meeting.

Board of Directors

Maynard, MA 01754

Lady and Gentlemen:

You have requested our opinion as to the fairness from a financial point of view to the holders (other than Cisco Systems, Inc. (“Parent”), and its affiliates) of the outstanding shares of common stock, par value $0.0001 per share (the “Shares”), of Acacia Communications, Inc. (the “Company”), of the $70.00 in cash per Share to be paid to such holders pursuant to the Agreement and Plan of Merger, dated as of July 8, 2019 (the “Agreement”), by and among Parent, Amarone Acquisition Corp., a wholly owned subsidiary of Parent, and the Company.

Goldman Sachs & Co. LLC and its affiliates are engaged in advisory, underwriting and financing, principal investing, sales and trading, research, investment management and other financial andnon-financial activities and services for various persons and entities. Goldman Sachs & Co. LLC and its affiliates and employees, and funds or other entities they manage or in which they invest or have other economic interests or with which theyco-invest, may at any time purchase, sell, hold or vote long or short positions and investments in securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments of the Company, Parent, any of their respective affiliates and third parties, or any currency or commodity that may be involved in the transaction contemplated by the Agreement (the “Transaction”). We have acted as financial advisor to the Company in connection with, and have participated in certain of the negotiations leading to, the Transaction. We expect to receive fees for our services in connection with the Transaction, the principal portion of which is contingent upon consummation of the Transaction, and the Company has agreed to reimburse certain of our expenses arising, and indemnify us against certain liabilities that may arise, out of our engagement. We have provided certain financial advisory and/or underwriting services to the Company and/or its affiliates from time to time. We also have provided certain financial advisory and/or underwriting services to Parent and/or its affiliates from time to time for which our Investment Banking Division has received, and may receive, compensation, including having acted as financial advisor to Parent in connection with its acquisition of Duo Security in October 2018 and as a commercial paper dealer for Parent since 2015. We may also in the future provide financial advisory and/or underwriting services to the Company and Parent and their respective affiliates for which our Investment Banking Division may receive compensation. In addition, a Director on the Board of Parent is currently affiliated with the Goldman Sachs Group, Inc. as a Director.

In connection with this opinion, we have reviewed, among other things, the Agreement; annual reports to stockholders and Annual Reports on Form10-K of the .Company for the three years ended December 31, 2018; the Company’s Registration Statement on FormS-1, including the prospectus contained therein dated May 13, 2016, relating to an initial public offering of the Company’s Shares; certain interim reports to stockholders and Quarterly Reports on Form10-Q of the Company; certain other communications from the Company to its stockholders; certain publicly available research analyst reports for the Company; and certain internal financial analyses and forecasts for the Company prepared by its management, as approved for our use by the Company (the “Forecasts”). We have also held discussions with members of the senior management of the Company regarding their assessment of the past and current business operations, financial condition and future prospects of

the Company; reviewed the reported price and trading activity for the Shares; compared certain financial and stock market information for the Company with similar information for certain other companies the securities of which are publicly traded; reviewed the financial terms of certain recent business combinations in the communication technology and semiconductor industries and in other industries; and performed such other studies and analyses, and considered such other factors, as we deemed appropriate.

For purposes of rendering this opinion, we have, with your consent, relied upon and assumed the accuracy and completeness of all of the financial, legal, regulatory, tax, accounting and other information provided to, discussed with or reviewed by, us, without assuming any responsibility for independent verification thereof. In that regard, we have assumed with your consent that the Forecasts have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of the Company. We have not made an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or otheroff-balance-sheet assets and liabilities) of the Company or any of its subsidiaries and we have not been furnished with any such evaluation or appraisal. We have assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the Transaction will be obtained without any adverse effect on the expected benefits of the Transaction in any way meaningful to our analysis. We have assumed that the Transaction will be consummated on the terms set forth in the Agreement, without the waiver or modification of any term or condition the effect of which would be in any way meaningful to our analysis.

Our opinion does not address the underlying business decision of the Company to engage in the Transaction, or the relative merits of the Transaction as compared to any strategic alternatives that may be available to the Company, including an expression of interest for a transaction proposed by a third party that may have resulted in a higher price per Share in cash than in the Transaction, which you have advised us, you have determined not to further pursue because of risks and uncertainties concerning such potential transaction, nor does it address any legal, regulatory, tax or accounting matters.

We do not express any view on, and our opinion does not address, any other term or aspect of the Agreement or Transaction or any term or aspect of any other agreement or instrument contemplated by the Agreement or entered into or amended in connection with the Transaction, including the fairness of the Transaction to, or any consideration received in connection therewith by, the holders of any other class of securities, creditors, or other constituencies of the Company; nor as to the fairness of the amount or nature of any compensation to be paid or payable to any of the officers, directors or employees of the Company, or class of such persons, in connection with the Transaction, whether relative to the $70.00 in cash per Share to be paid to the holders (other than Parent and its affiliates) of Shares pursuant to the Agreement or otherwise.

C-1

the Company, preventing or materially delaying the consummation of any of the transactions contemplated hereby;provided that to the extent Stockholder is a director or officer of the Company, such Stockholder may, in his or her capacity as a director or officer of the Company, take such actions as may be permitted under Section 5.2 and Section 5.3 of the Merger Agreement.

(a) Stockholder is the beneficial or record owner of, or exercises voting power over, that number of shares of Company Common Stock set forth on the signature page hereto (all such shares owned beneficially or of record by Stockholder, or over which Stockholder exercises voting power, on the date hereof, collectively, the “Shares”). Stockholder does not hold any other outstanding shares of capital stock of the Company. No person not a signatory to this Agreement has a beneficial interest in or a right to acquire or vote any of the Shares (other than, (i) if Stockholder is a partnership, the rights and interest of persons and entities that own partnership interests in Stockholder under the partnership agreement governing Stockholder and applicable partnership law or (ii) if Stockholder is a married individual and resides in a State with community property laws, the community property interest of his or her spouse to the extent applicable under such community property law, in which case such spouse has executed a spousal consent hereto if requested by Parent). The Shares are and will be at all times up until the Expiration Date free and clear of any security interests, liens, claims, pledges, options, rights of first refusal,co-sale rights, agreements, limitations on Stockholder’s voting rights, charges and other encumbrances of

C-2

any nature that would materially and adversely affect the ability of Stockholder to perform his, her or its obligations under this Agreement. Stockholder’s principal residence or place of business is set forth on the signature page hereto.

(b) Stockholder has all requisite power, capacity and authority to enter into this Agreement and to consummate the transactions contemplated hereby. The execution and delivery of this Agreement by Stockholder and the consummation by Stockholder of the transactions contemplated hereby have been duly authorized by all necessary action, if any, on the part of Stockholder. This Agreement has been duly executed and delivered by Stockholder and, assuming the due authorization, execution and delivery of this Agreement by Parent, constitutes a valid and binding obligation of Stockholder, enforceable against Stockholder in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and remedies generally and to general principles of equity.

(c) The execution and delivery of this Agreement does not, and the consummation of the transactions contemplated hereby and compliance with the provisions hereof will not, conflict with, result in a breach or violation of or default (with or without notice or lapse of time or both) under, or require notice to or the consent of any person under, any agreement, law, rule, regulation, judgment, order or decree by which Stockholder is bound, except for such conflicts, breaches, violations or defaults that would not, individually or in the aggregate, prevent or materially delay Stockholder from performing his, her or its obligations under this Agreement.

5.Consent and Waiver. Stockholder hereby waives any and all rights to contest or object to the execution and delivery of the Merger Agreement, the Company Board of Directors’ actions in approving and recommending the Merger, the consummation of the Merger and the other transactions provided for in the Merger Agreement, or to seek damages or other legal or equitable relief in connection therewith (but for the avoidance of doubt this waiver does not extend to any claims relating to any breach of the Merger Agreement). From and after the Effective Time, Stockholder’s right to receive cash on the terms and subject to the conditions set forth in the Merger Agreement shall constitute Stockholder’s sole and exclusive right against the Company and/or Parent in respect of Stockholder’s ownership of the Shares or status as a stockholder of the Company or any agreement or instrument with the Company pertaining to the Shares or Stockholder’s status as a stockholder of the Company.

6.Confidentiality.

7.Appraisal Rights. Stockholder agrees not to exercise any rights of appraisal or any dissenters’ rights that Stockholder may have (whether under applicable law or otherwise) or could potentially have or acquire in connection with the Merger.

(b)Interpretation. When a reference is made in this Agreement to Sections or Exhibits, such reference shall be to a Section of or an Exhibit to this Agreement unless otherwise indicated.

(c)Specific Performance; Injunctive Relief. The parties hereto acknowledge that Parent will be irreparably harmed and that there will be no adequate remedy at law for a violation of any of the covenants or agreements of Stockholder set forth herein or in the Irrevocable Proxy. Therefore, it is agreed that, in addition to any other remedies that may be available to Parent upon any such violation of this Agreement or the Irrevocable Proxy, Parent shall have the right to seek to enforce such covenants and agreements and the Irrevocable Proxy by specific performance, injunctive relief or by any other means available to Parent at law or in equity and Stockholder hereby waives any requirement for the security or posting of any bond in connection with such enforcement.

C-4

the subject matter hereof and (ii) are not intended to confer, and shall not be construed as conferring, upon any person other than the parties hereto any rights or remedies hereunder.

Subject to the preceding sentence, this Agreement shall be binding upon, inure to the benefit of, and be enforceable by, the parties hereto and their respective permitted successors and assigns (including any person to whom any Shares are sold, transferred or assigned).

(f)Severability. In the event that any provision of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement shall continue in full force and effect and the application of such provision to other persons or circumstances shall be interpreted so as reasonably to effect the intent of the parties hereto. The parties hereto further agree to use their commercially reasonable efforts to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that shall achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision.

(g)Remedies Cumulative. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party shall be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy shall not preclude the exercise of any other remedy.

(h)Governing Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of Delaware without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of laws of any jurisdictions other than those of the State of Delaware. The parties hereto hereby irrevocably submit to the exclusive jurisdiction the Court of Chancery of the State of Delaware, New Castle County, or, if that court does not have jurisdiction, a federal court sitting in Wilmington, Delaware, solely in respect of the interpretation and enforcement of the provisions of this Agreement and of the documents referred to in this Agreement, and in respect of the transactions contemplated hereby and thereby, and hereby waive, and agree not to assert, as a defense in any action, suit or proceeding for the interpretation or enforcement hereof or thereof, that it is not subject thereto or that such action, suit or proceeding may not be brought or is not maintainable in said courts or that the venue thereof may not be appropriate or that this Agreement or any such document may not be enforced in or by such courts, and the parties hereto irrevocably agree that all claims with respect to such action or proceeding shall be heard and determined in such a Delaware state or federal court. The parties hereby consent to and grant any such court jurisdiction over the person of such parties and over the subject matter of such dispute and agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 8(a) or in such other manner as may be permitted by applicable law, shall be valid and sufficient service thereof.

(i)Rules of Construction. The parties hereto agree that they have been represented by counsel during the negotiation, preparation and execution of this Agreement and, therefore, waive the application of any law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document shall be construed against the party drafting such agreement or document.

(j)Additional Documents, Etc. Stockholder shall execute and deliver any additional documents necessary or desirable, in the reasonable opinion of Parent, to carry out the purpose and intent of this Agreement. Without limiting the generality or effect of the foregoing or any other obligation of Stockholder hereunder, Stockholder hereby authorizes Parent to deliver a copy of this Agreement to the Company and hereby agrees that

C-5

each of the Company and Parent may rely upon such delivery as conclusively evidencing the consents and waivers of Stockholder referred to in Section 5, in each case for purposes of all agreements and instruments to which such elections, consents and/or waivers are applicable or relevant.

(k)WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT, OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE ACTIONS OF ANY PARTY HERETO IN NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT HEREOF.

(l)Fiduciary Duties. Notwithstanding anything in this Agreement to the contrary, (i) Stockholder makes no agreement or understanding herein in any capacity other than in Stockholder’s capacity as a record holder and beneficial owner of the Shares and the New Shares, and not in such Stockholder’s capacity as a director, officer or employee of the Company or any of the Subsidiaries or in such Stockholder’s capacity as a trustee or fiduciary of any Company Employee Plan and (ii) nothing herein will be construed to limit or affect any action or inaction by Stockholder or any representative of Stockholder, as applicable, serving on the Company Board or on the board of directors of any Subsidiary or as an officer or fiduciary of the Company or any Subsidiary, acting in such person’s capacity as a director, officer, employee or fiduciary of the Company or any Subsidiary.

(m)Term. This Agreement and all obligations hereunder shall terminate upon the Expiration Date. Upon termination of this Agreement, no party shall have any further obligations or liabilities under this Agreement;provided that (i) nothing set forth in this Section 8(m) shall relieve any party from liability for any intentional breach of this Agreement prior to termination hereof and (ii) the provisions of this Section 8(m) shall survive any termination of this Agreement.

(b) Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to § 251 (other than a merger effected pursuant to § 251(g) of this title), § 252, § 254, § 255, § 256, § 257, § 258, § 263 or § 264 of this title:

(1) Provided, however, that, except as expressly provided in § 363(b) of this title, no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of the meeting of stockholders to act upon the agreement of merger or consolidation (or, in the case of a merger pursuant to § 251(h), as of immediately prior to the execution of the agreement of merger), were either: (i) listed on a national securities exchange or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in § 251(f) of this title.

(2) Notwithstanding paragraph (b)(1) of this section, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to §§ 251, 252, 254, 255, 256, 257, 258, 263 and 264 of this title to accept for such stock anything except:

D-1

practicable, with the word “amendment” substituted for the words “merger or consolidation,” and the word “corporation” substituted for the words “constituent corporation” and/or “surviving or resulting corporation.”

(c) Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the provisions of this section, including those set forth in subsections (d), (e), and (g) of this section, shall apply as nearly as is practicable.

(d) Appraisal rights shall be perfected as follows:

(1) If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for notice of such meeting (or such members who received notice in accordance with § 255(c) of this title) with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) of this section that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section and, if 1 of the constituent corporations is a nonstock corporation, a copy of § 114 of this title. Each stockholder electing to demand the appraisal of such stockholder’s shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of such stockholder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder’s shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or

(2) If the merger or consolidation was approved pursuant to § 228, § 251(h), § 253, or § 267 of this title, then either a constituent corporation before the effective date of the merger or consolidation or the surviving or resulting corporation within 10 days thereafter shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of this section and, if 1 of the constituent corporations is a nonstock corporation, a copy of § 114 of this title. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice or, in the case of a merger approved pursuant to § 251(h) of this title, within the later of the consummation of the offer contemplated by § 251(h) of this title and 20 days after the date of mailing of such notice, demand in writing from the surviving or resulting corporation the appraisal of such holder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder’s shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice or, in the case of a merger approved pursuant to § 251(h) of this title, later than the later of the consummation of the offer contemplated by § 251(h) of this

D-2

title and 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder’s shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given.

(e) Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) of this section hereof and who is otherwise entitled to appraisal rights, may commence an appraisal proceeding by filing a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party shall have the right to withdraw such stockholder’s demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) of this section hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation (or, in the case of a merger approved pursuant to § 251(h) of this title, the aggregate number of shares (other than any excluded stock (as defined in § 251(h)(6)d. of this title)) that were the subject of, and were not tendered into, and accepted for purchase or exchange in, the offer referred to in § 251(h)(2)), and, in either case, with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder’s written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) of this section hereof, whichever is later. Notwithstanding subsection (a) of this section, a person who is the beneficial owner of shares of such stock held either in a voting trust or by a nominee on behalf of such person may, in such person’s own name, file a petition or request from the corporation the statement described in this subsection.

(f) Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation.

(g) At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder. If immediately before the merger or consolidation the shares of the class or series of stock of the constituent

D-3

corporation as to which appraisal rights are available were listed on a national securities exchange, the Court shall dismiss the proceedings as to all holders of such shares who are otherwise entitled to appraisal rights unless (1) the total number of shares entitled to appraisal exceeds 1% of the outstanding shares of the class or series eligible for appraisal, (2) the value of the consideration provided in the merger or consolidation for such total number of shares exceeds $1 million, or (3) the merger was approved pursuant to § 253 or § 267 of this title.

(h) After the Court determines the stockholders entitled to an appraisal, the appraisal proceeding shall be conducted in accordance with the rules of the Court of Chancery, including any rules specifically governing appraisal proceedings. Through such proceeding the Court shall determine the fair value of the shares exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. Unless the Court in its discretion determines otherwise for good cause shown, and except as provided in this subsection, interest from the effective date of the merger through the date of payment of the judgment shall be compounded quarterly and shall accrue at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the merger and the date of payment of the judgment. At any time before the entry of judgment in the proceedings, the surviving corporation may pay to each stockholder entitled to appraisal an amount in cash, in which case interest shall accrue thereafter as provided herein only upon the sum of (1) the difference, if any, between the amount so paid and the fair value of the shares as determined by the Court, and (2) interest theretofore accrued, unless paid at that time. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, proceed to trial upon the appraisal prior to the final determination of the stockholders entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder’s certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section.

(i) The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court’s decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state.

(j) The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney’s fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal.

(k) From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder’s demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just; provided, however that this provision shall not affect the right of any stockholder who has not

D-4

commenced an appraisal proceeding or joined that proceeding as a named party to withdraw such stockholder’s demand for appraisal and to accept the terms offered upon the merger or consolidation within 60 days after the effective date of the merger or consolidation, as set forth in subsection (e) of this section.

(l) The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation.
