AGREEMENT AND PLAN OF MERGER

THIS AGREEMENT AND PLAN OF MERGER (“Agreement”) is made and entered into as of August 8, 2023, by and among: Regeneron Pharmaceuticals, Inc., a New York corporation (“Parent”); Symphony Acquisition Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Purchaser”); and Decibel Therapeutics, Inc., a Delaware corporation (the “Company”). Certain capitalized terms used in this Agreement are defined in Exhibit A.

RECITALS

(A) Parent has agreed to cause Purchaser to commence a tender offer (as it may be amended or extended from time to time as permitted under this Agreement, the “Offer”) to acquire all of the outstanding shares of Company Common Stock (the “Shares” and each such share of Company Common Stock, a “Share”), other than the Excluded Shares and the Converted Shares, for (i) $4.00 per Share, to be paid to the seller in cash, without interest and subject to reduction for any applicable withholding Taxes (the “Cash Consideration”) plus (ii) one (1) contractual contingent value right per Share, which shall represent the right to potentially receive following the Closing the Milestone Payments, in each case upon the terms and subject to the conditions of the CVR Agreement (as defined below), without interest and subject to reduction for any applicable withholding Taxes (a “CVR”) (the Cash Consideration together with the CVR, or any higher amount per Share paid pursuant to the Offer, and as may be adjusted in accordance with Section 1.1(g), the “Offer Consideration”), upon the terms and subject to the conditions of this Agreement.

(B) Regardless of whether the Offer Acceptance Time occurs, Purchaser will be merged with and into the Company (the “Merger”), with the Company continuing as the surviving corporation in the Merger (the “Surviving Corporation”), on the terms and subject to the conditions set forth in this Agreement, whereby (i) each issued and outstanding Share as of the Effective Time (other than Excluded Shares, Converted Shares and Dissenting Shares) shall be converted into the right to receive the Merger Consideration, without interest, and subject to reduction for any applicable withholding Taxes in accordance with Section 2.6(e) and (ii) the Company shall become a wholly owned Subsidiary of Parent as a result of the Merger.

(C) Subject to the terms and conditions of this Agreement, at or prior to the Offer Acceptance Time, Parent and a rights agent mutually agreeable to Parent and the Company (the “Rights Agent”) will enter into a Contingent Value Rights Agreement in substantially the form attached hereto as Exhibit B (subject to changes permitted by Section 6.15) (the “CVR Agreement”).

(D) The board of directors of the Company (the “Board of Directors”) has unanimously (i) determined that this Agreement and the Transactions, including the Offer and the Merger, are fair to, and in the best interest of, the Company and its stockholders, (ii) declared it advisable to enter into this Agreement, (iii) approved the execution, delivery and performance by the Company of this Agreement and the consummation of the Transactions, including the Offer and the Merger, (iv) resolved that (a) if the Offer Acceptance Time occurs, the Merger shall be effected under Section 251(h) of the DGCL and will be effected as soon as practicable following the consummation of the Offer, and (b) if an Offer Termination occurs, the Merger will be governed

by Section 251(c) of the DGCL, in each case, upon the terms and subject to the conditions set forth herein, and (v) resolved to recommend that the stockholders of the Company (1) accept the Offer and tender their Shares to Purchaser pursuant to the Offer and (2) adopt this Agreement at any meeting of the Company’s stockholders held for such purpose and any adjournment or postponement thereof (collectively, the “Company Board Recommendation”), in each case, on the terms and subject to the conditions of this Agreement.

(E) The board of directors of Purchaser has (i) approved this Agreement and declared it advisable for Purchaser to enter into this Agreement, and (ii) approved the execution and delivery by Purchaser of this Agreement, the performance by Purchaser of its covenants and agreements contained herein and the consummation of the Offer and the Merger upon the terms and subject to the conditions contained herein.

(F) The board of directors of Purchaser has recommended that Parent, as the sole stockholder of Purchaser, adopt this Agreement by written consent in lieu of a meeting, which consent shall by its terms be effective immediately following the execution and delivery of this Agreement.

(G) Parent, Purchaser and the Company acknowledge and agree that (a) if the Offer Acceptance Time occurs, the Merger shall be effected under Section 251(h) of the DGCL and will be effected as soon as practicable following the consummation of the Offer, and (b) if an Offer Termination occurs, the Merger will be governed by Section 251(c) of the DGCL, in each case, upon the terms and subject to the conditions set forth herein.

(H) As a condition and inducement to the willingness of Parent and Purchaser to enter into this Agreement, concurrently with the execution and delivery of this Agreement, certain of the Company’s stockholders are entering into tender and support agreements with Parent and Purchaser (the “Support Agreements”) pursuant to which, among other things, each such stockholder has agreed to tender all of its Shares to Purchaser in the Offer and (if applicable) vote all of its Shares in favor of the Merger, in each case on the terms and subject to the conditions set forth therein.

AGREEMENT

The Parties to this Agreement, intending to be legally bound, agree as follows:

SECTION 1

THE OFFER

1.1 The Offer.

(a) Commencement of the Offer. Provided that this Agreement shall not have been terminated in accordance with Section 8, as promptly as practicable after the date of this Agreement but in no event more than fifteen (15) business days after the date of this Agreement (subject to the Company having timely provided any information required to be provided by it pursuant to Sections 1.1(e) and 1.2(b)), Purchaser shall (and Parent shall cause Purchaser to) commence (within the meaning of Rule 14d-2 under the Exchange Act) the Offer to purchase all of the outstanding Shares (other than Shares to be cancelled pursuant to Sections 2.5(a)(i) and 2.5(a)(ii) (collectively, the “Excluded Shares”)), and other than Shares to be converted pursuant to Section 2.5(a)(iii) (collectively, the “Converted Shares”)), in exchange for the Offer Consideration, without interest, and subject to reduction for any applicable withholding Taxes in accordance with Section 2.6(e).

(b) Terms and Conditions of the Offer. If the Offer Termination has not occurred, the obligations of Purchaser to, and of Parent to cause Purchaser to, accept for payment, and pay for, any Shares validly tendered (and not validly withdrawn) pursuant to the Offer are subject only to the terms and conditions set forth in this Agreement, including the satisfaction of the Minimum Condition and the Termination Condition, and the satisfaction or waiver of the other conditions set forth in Annex I (collectively, the “Offer Conditions”). The Offer shall be made by means of an offer to purchase (the “Offer to Purchase”) that contains the terms set forth in this Agreement, the Minimum Condition, the Termination Condition and the other Offer Conditions. Purchaser and Parent expressly reserve the right to (i) increase the amount of the Cash Consideration or the amount of any Milestone Payment, (ii) waive any Offer Condition other than the Minimum Condition, the Termination Condition or the conditions set forth in clauses (e) and (g) (solely in respect of any Antitrust Law) of Annex I and (iii) make any other changes in the terms and conditions of the Offer not inconsistent with the terms of this Agreement; provided, however, notwithstanding anything to the contrary contained in this Agreement, without the prior written consent of the Company, Parent and Purchaser shall not (A) decrease the amount of the Cash Consideration or the amount of any Milestone Payment or otherwise amend any of the terms or conditions of the CVR Agreement in a manner adverse to any holder of Shares in its capacity as such, (B) change the form of consideration payable in the Offer, (C) decrease the maximum number of Shares sought to be purchased in the Offer, (D) impose conditions to the Offer in addition to the Offer Conditions, (E) amend, modify or waive the Minimum Condition, the Termination Condition or the conditions set forth in clauses (e) and (g) (solely in respect of any Antitrust Law) of Annex I, (F) otherwise amend or modify any of the Offer Conditions in a manner that adversely affects, or would reasonably be expected to adversely affect, any holder of Shares in its capacity as such, (G) terminate the Offer or accelerate, extend or otherwise change the Expiration Date, in each case, except as provided in Sections 1.1(c), 1.1(d) or 5.4 (including, for the avoidance of doubt, in connection with an Offer Termination), or (H) provide any “subsequent offering period” (or any extension thereof) within the meaning of Rule 14d-11 promulgated under the Exchange Act. The Offer may not be terminated or withdrawn prior to the Expiration Date (or any rescheduled Expiration Date) of the Offer, unless this Agreement is terminated in accordance with Section 8 or the Offer is terminated or withdrawn in connection with an Offer Termination.

(c) Expiration and Extension of the Offer. The Offer shall initially be scheduled to expire at one minute after 11:59 p.m. Eastern Time on the date that is twenty (20) business days (determined as set forth in Rule 14d-1(g)(3) and Rule 14e-1(a) under the Exchange Act) from the Offer Commencement Date (unless otherwise agreed to in writing by Parent and the Company) (the “Initial Expiration Date,” and such date and time or such subsequent date and time to which the expiration of the Offer is extended in accordance with the terms of this Agreement, the “Expiration Date”). Notwithstanding anything to the contrary contained in this Agreement, but subject to the Parties’ respective termination rights under Section 8: (i) if, as of the then-scheduled Expiration Date, any Offer Condition is not satisfied and has not been waived by Purchaser or Parent, to the extent waivable by Purchaser or Parent, Purchaser may, in its discretion

(and without the consent of the Company or any other Person), extend the Offer on one or more occasions, for an extension period of up to ten (10) business days per extension, to permit such Offer Condition to be satisfied; and (ii) subject to Purchaser’s right to terminate the Offer and pursue the Merger in connection with an Offer Termination pursuant to Section 1.1(d), (A) if, as of the then-scheduled Expiration Date, any Offer Condition (other than (x) the Offer Condition set forth in clause (f) of Annex I and (y) the Minimum Condition) is not satisfied and has not been waived by Purchaser or Parent, to the extent waivable by Purchaser or Parent, upon the Company’s written request, Purchaser shall, and Parent shall cause Purchaser to, extend the Offer for successive extension periods of ten (10) business days per extension, to permit such Offer Condition to be satisfied, (B) if, as of the then-scheduled Expiration Date, the Minimum Condition is not satisfied but all other Offer Conditions (other than the Offer Condition set forth in clause (f) of Annex I) have been satisfied or waived, at the written request of the Company, Purchaser shall, and Parent shall cause Purchaser to, extend the Offer on up to two (2) occasions for an additional period of up to ten (10) business days per extension, to permit the Minimum Condition to be satisfied and (C) Purchaser shall, and Parent shall cause Purchaser to, extend the Offer from time to time for any period required by any Legal Requirement, any interpretation or position of the SEC, the staff thereof or NASDAQ applicable to the Offer; provided, however, that in no event shall Purchaser: (1) be required to extend the Offer beyond the earlier to occur of (x) the valid termination of this Agreement in compliance with Section 8 and (y) the End Date (such earlier occurrence, the “Extension Deadline”); or (2) be permitted to extend the Offer beyond the Extension Deadline without the prior written consent of the Company; provided that, in each case, the extensions contemplated by this Section 1.1(c) shall be subject to Purchaser’s right to terminate the Offer and pursue the Merger in connection with an Offer Termination pursuant to Section 1.1(d). Except (i) as provided in Section 1.1(d), (ii) in the event that this Agreement is terminated pursuant to Section 8 or (iii) if Purchaser is not obligated to extend the Offer as provided in this Section 1.1(c), Purchaser shall not terminate the Offer, or permit the Offer to expire, prior to any scheduled Expiration Date without the prior written consent of the Company.

(d) Termination of Offer. Nothing in this Section 1.1 shall be deemed to impair, limit or otherwise restrict in any manner the right of the Company, Parent or Purchaser to terminate this Agreement pursuant to Section 8. If Parent delivers a Meeting Election, Purchaser shall (and Parent shall cause Purchaser to) promptly terminate and withdraw the Offer or permit the Offer to expire without accepting for payment, and without paying for, any Shares pursuant to the Offer. The termination or expiration of the Offer by Purchaser pursuant to the preceding sentence is referred to in this Agreement as an “Offer Termination.” The Parties hereto acknowledge and agree that in no event shall an Offer Termination following a valid Meeting Election in accordance with the terms of this Agreement, in and of itself give, rise to a right of termination of this Agreement, and, if an Offer Termination occurs, (i) absent any valid termination of this Agreement pursuant to Section 8, the obligations of the Parties hereunder (other than those related to the Offer) shall continue to remain in effect, including those obligations with respect to the Merger, (ii) Purchaser shall not (and Parent shall cause Purchaser not to) (A) acquire any Shares pursuant to the Offer, or (B) without the Company’s prior written consent, commence within the meaning of Rule 14d-2 promulgated under the Exchange Act another tender offer or exchange offer with respect to the Shares after the Offer Termination and (iii) the text of clause (v)(1) of the definition of “Company Board Recommendation” shall be deemed to have been deleted in its entirety. If this Agreement is validly terminated pursuant to Section 8, Purchaser shall (and Parent shall cause Purchaser to) promptly, irrevocably and unconditionally terminate the Offer and shall not acquire any Shares pursuant to the Offer. If the Offer is terminated or withdrawn by Purchaser in accordance with the terms of this Agreement, Purchaser shall promptly return, and shall cause any depository acting on behalf of Purchaser to return, in accordance with applicable Legal Requirements, all tendered Shares to the registered holders thereof.

(e) Offer Documents. As promptly as practicable on the Offer Commencement Date, Parent and Purchaser shall (i) file with the SEC a tender offer statement on Schedule TO with respect to the Offer (together with any exhibits, amendments or supplements thereto, including the Offer to Purchase and form of the related letter of transmittal, the “Offer Documents”) that will contain or incorporate by reference the Offer to Purchase and form of the related letter of transmittal and (ii) cause the Offer to Purchase and related documents to be disseminated to holders of Shares as and to the extent required by applicable Legal Requirements. Parent and Purchaser agree that they shall cause the Offer Documents filed by either Parent or Purchaser with the SEC (x) to comply in all material respects with the Exchange Act and other applicable Legal Requirements and (y) to not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that no covenant is made by Parent or Purchaser with respect to information supplied by or on behalf of the Company for inclusion or incorporation by reference in the Offer Documents. Each of Parent, Purchaser and the Company agrees to respond promptly to any comments of the SEC or its staff and to promptly correct any information provided by it for use in the Offer Documents if and to the extent that such information shall have become false or misleading in any material respect, and Parent and Purchaser further agree to take all steps necessary to promptly cause the Offer Documents as so corrected to be filed with the SEC and to be disseminated to holders of Shares, in each case as and to the extent required by applicable Legal Requirements. The Company consents to the inclusion of the Company Board Recommendation in the Offer Documents (unless the Board of Directors has made a Company Adverse Recommendation Change in compliance with Section 6.1(b)). The Company shall promptly furnish or otherwise make available to Parent and Purchaser or Parent’s legal counsel all information concerning the Company and the Company’s stockholders that may be required or reasonably requested in connection with any action contemplated by this Section 1.1(e). The Company and its counsel shall be given reasonable opportunity to review and comment on the Offer Documents (including any response to any comments (including oral comments) of the SEC or its staff with respect thereto) prior to the filing thereof with the SEC, and Parent and Purchaser shall give reasonable and good faith consideration to any such comments made by the Company or its counsel. Parent and Purchaser agree to provide the Company and its counsel with any comments (including oral comments) Parent, Purchaser or their counsel may receive from the SEC or its staff with respect to the Offer Documents promptly after receipt of those comments (including oral comments).

(f) Funds. Without limiting the generality of Section 9.10, Parent shall cause to be provided to Purchaser, on a timely basis (and in any event prior to the Offer Acceptance Time), all of the funds necessary to purchase all Shares that Purchaser becomes obligated to purchase pursuant to the Offer, and shall cause Purchaser to perform, on a timely basis, all of Purchaser’s obligations under this Agreement. Parent and Purchaser shall, and each of Parent and Purchaser shall ensure that all of their respective controlled Affiliates shall, tender any Shares held by them into the Offer.

(g) Adjustments. If, between the date of this Agreement and the Offer Acceptance Time, the outstanding Shares are changed into a different number or class of shares by reason of any stock split, division or subdivision of shares, stock dividend, reverse stock split, consolidation of shares, reclassification, recapitalization or other similar transaction, then the Offer Consideration and the Merger Consideration shall be appropriately adjusted; provided, that nothing in this Section 1.1(g) shall be construed to permit the Company to take any action that is prohibited by the terms of this Agreement.

(h) Acceptance. Subject only to the satisfaction or, to the extent waivable by Purchaser or Parent, waiver by Purchaser or Parent of each of the Offer Conditions, Purchaser shall (and Parent shall cause Purchaser to) (i) promptly after (and in any event prior to 9:30 a.m. Eastern Time on the business day following) the Expiration Date, irrevocably accept for payment all Shares tendered (and not validly withdrawn) pursuant to the Offer (the time of such acceptance, the “Offer Acceptance Time”) and (ii) deposit, or cause to be deposited, with the Paying Agent (as defined below) the Payment Fund (as defined below), in accordance with Section 2.6(a).

(i) Notification of Offer Status. Parent shall, upon the reasonable request of the Company, advise the Company on a daily basis on each of the last seven (7) business days prior to the then-scheduled Expiration Date as to the number of Shares that have been validly tendered and not validly withdrawn in accordance with the terms of the Offer.

1.2 Company Actions.

(a) Schedule 14D-9. As promptly as practicable on the Offer Commencement Date, following the filing of the Schedule TO that forms a part of the Offer Documents, the Company shall (i) file with the SEC a Tender Offer Solicitation/Recommendation Statement on Schedule 14D-9 (together with any exhibits, amendments or supplements thereto, the “Schedule 14D-9”) that includes the Company Board Recommendation (unless the Board of Directors has made a Company Adverse Recommendation Change in accordance with Section 6.1(b)) and the notice and other information required by Section 262(d)(2) of the DGCL and (ii) cause the Schedule 14D-9 and related documents to be disseminated to holders of Shares as and to the extent required by applicable Legal Requirements, including by setting the Stockholder List Date as the record date for purposes of receiving the notice required by Section 262(d)(2) of the DGCL. The Company agrees that it shall cause the Schedule 14D-9 (x) to comply in all material respects with the Exchange Act and other applicable Legal Requirements and (y) to not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that no covenant is made by the Company with respect to information supplied by or on behalf of Parent or Purchaser for inclusion or incorporation by reference in the Schedule 14D-9. Each of Parent, Purchaser and the Company agrees to respond promptly to any comments of the SEC or its staff and to promptly correct any information provided by it for use in the Schedule 14D-9 if and to the extent that such information shall have become false or misleading in any material respect, and the Company further agrees to take all steps necessary to promptly cause the Schedule 14D-9 as so corrected to be filed with the SEC and to be disseminated to holders of Shares, in each case as and to the extent required by applicable Legal Requirements. Parent and Purchaser shall promptly furnish or otherwise make available to the Company or the Company’s legal counsel all information concerning Parent or

Purchaser that may be required or reasonably requested in connection with any action contemplated by this Section 1.2(a). Except with respect to any disclosure regarding a Company Adverse Recommendation Change made in compliance with Section 6.1, Parent and its counsel shall be given reasonable opportunity to review and comment on the Schedule 14D-9 (including any response to any comments (including oral comments) of the SEC or its staff with respect thereto) prior to the filing thereof with the SEC, and the Company shall give reasonable and good faith consideration to any such comments made by Parent or its counsel. Except with respect to any disclosure regarding a Company Adverse Recommendation Change made in compliance with Section 6.1, the Company agrees to provide Parent and its counsel with any comments (including oral comments) the Company or its counsel may receive from the SEC or its staff with respect to the Schedule 14D-9 promptly after receipt of those comments (including oral comments). To the extent requested by the Company, Parent shall cause the Schedule 14D-9 to be mailed or otherwise disseminated to the holders of Company Common Stock together with the Offer Documents disseminated to the holders of Shares.

(b) Stockholder Lists. The Company shall (or shall cause its transfer agent to) promptly furnish Parent with a list of its stockholders, mailing labels and any available listing or computer file containing the names and addresses of all record holders of Shares and lists of securities positions of Shares held in stock depositories, in each case accurate and complete (except for de minimis inaccuracies), as of the most recent practicable date, and shall provide to Parent such additional information (including updated lists of stockholders, mailing labels and lists of securities positions) and such other assistance as Parent may reasonably request in connection with the Offer and the Merger (the date of the list used to determine the Persons to whom the Offer Documents and the Schedule 14D-9 are first disseminated, which date shall not be more than ten (10) days prior to the date the Offer Documents and the Schedule 14D-9 are first disseminated, the “Stockholder List Date”). Subject to applicable Legal Requirements, and except for such steps as are necessary to disseminate the Offer Documents and any other documents necessary to consummate the Transactions, Parent and Purchaser and their agents shall hold in confidence the information contained in any such labels, listings and files in accordance with the Confidentiality Agreement, shall not use such information in violation thereof and, if this Agreement shall be terminated, shall, upon request by the Company, deliver, and shall use their reasonable best efforts to cause their agents to deliver, to the Company (or, at Parent’s option, destroy) all copies and any extracts or summaries from such information then in their possession or control, and, if requested by the Company, promptly certify to the Company in writing that all such material has been returned or destroyed.

(c) Share Registry. The Company shall register (and shall instruct its transfer agent to register) the transfer of the Shares irrevocably accepted for payment by Purchaser effective immediately after the Offer Acceptance Time.

The date on which the Closing occurs is referred to in this Agreement as the “Closing Date.”

(b) Subject to the provisions of this Agreement, as soon as practicable on the Closing Date, the Company and Purchaser shall file or cause to be filed a certificate of merger with the Secretary of State of the State of Delaware with respect to the Merger, in such form as required by, and executed and acknowledged in accordance with, the relevant provisions of the DGCL, and the Parties shall take all such further actions as may be required by applicable Legal Requirements to make the Merger effective. The Merger shall become effective upon the date and time of the filing of that certificate of merger with the Secretary of State of the State of Delaware or such later date and time as is agreed upon in writing by the Parties and specified in the certificate of merger (such date and time, the “Effective Time”).

(a) At the Effective Time, by virtue of the Merger and without any further action on the part of Parent, Purchaser, the Company or any stockholder of the Company:

(i) any Shares held immediately prior to the Effective Time by the Company (or held in the Company’s treasury) shall automatically be cancelled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor;

(ii) any Shares held immediately prior to the Effective Time by Parent or Purchaser shall automatically be cancelled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor;

(iii) any Shares held immediately prior to the Effective Time by any direct or indirect wholly owned Subsidiary of Parent (other than Purchaser) or of the Company shall be converted into such number of shares of stock of the Surviving Corporation such that each such Subsidiary shall own the same percentage of the outstanding capital stock of the Surviving Corporation immediately following the Effective Time as such Subsidiary owned in the Company immediately prior to the Effective Time and no other consideration shall be delivered in exchange therefor;

(iv) except as provided in clauses (i), (ii) and (iii) above, each Share outstanding immediately prior to the Effective Time (other than any Dissenting Shares, which shall have only those rights set forth in Section 2.7) shall be converted into the right to receive the Offer Consideration in the same form as the Offer Consideration, without any interest thereon and subject to any applicable withholding Tax in accordance with Section 2.6(e) (as may be adjusted in accordance with Section 2.5(b), the “Merger Consideration”); and

(v) each share of the common stock, $0.01 par value per share, of Purchaser then outstanding shall be converted into one share of common stock of the Surviving Corporation.

From and after the Effective Time, subject to Section 2.5(a)(iii), all Shares shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and each applicable holder of such Shares shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration therefor upon the surrender of such shares of Company Common Stock in accordance with Section 2.6 or, with respect to Dissenting Shares, only those rights set forth in Section 2.7.

(b) Without duplication of Section 1.1(g), if, between the date of this Agreement and the Effective Time, the outstanding Shares are changed into a different number or class of shares by reason of any stock split, division or subdivision of shares, stock dividend, reverse stock split, consolidation of shares, reclassification, recapitalization or other similar transaction, then the Merger Consideration shall be appropriately adjusted; provided, that nothing in this Section 2.5(b) shall be construed to permit the Company to take any action that is prohibited by the terms of this Agreement.

2.6 Surrender of Certificates; Stock Transfer Books.

(a) Prior to the Offer Acceptance Time, Parent shall designate a bank or trust company reasonably acceptable to the Company to act as agent (the “Depository Agent”) for the holders of Shares to receive the aggregate Cash Consideration to which holders of such Shares shall become entitled pursuant to Section 1.1(h) and to act as agent (the “Paying Agent”) for the holders of Shares to receive the aggregate cash portion of the Merger Consideration to which holders of such Shares shall become entitled pursuant to Section 2.5 and, in connection therewith, prior to the Closing Date, Parent shall enter into an agreement with the Paying Agent with terms reasonably acceptable to the Company. On or prior to the date of the Offer Acceptance Time, Parent shall deposit, or shall cause to be deposited, with the Depository Agent cash sufficient to make prompt payment of the aggregate Cash Consideration payable. On or prior to the Closing Date, Parent shall deposit, or shall cause to be deposited, with the Paying Agent cash sufficient to pay the aggregate cash portion of the Merger Consideration payable pursuant to Section 2.5 (together with the amount deposited pursuant the immediately preceding sentence, the “Payment Fund”). For the avoidance of doubt, neither Parent nor Purchaser shall be required to deposit any funds related to any Milestone Payment with the Rights Agent unless and until such deposit is required pursuant to the terms of the CVR Agreement. The Payment Fund shall not be used for any purpose other than to pay the aggregate Cash Consideration in the Offer and the aggregate cash portion of the Merger Consideration in the Merger. The Payment Fund shall be invested by the Paying Agent as directed by Parent or the Surviving Corporation; provided that such investments shall be (x) in obligations of or guaranteed by the United States of America, or (y) in United States government or United States treasury money market funds having a rating in the highest investment category granted by a recognized credit rating agency at the time of acquisition

or a combination of the foregoing and, in any such case, no such instrument shall have a maturity exceeding three (3) months. To the extent that there are losses with respect to such investments, or the Payment Fund diminishes for other reasons below the level required to make prompt payment of the Cash Consideration and the aggregate cash portion of the Merger Consideration as contemplated hereby, Parent shall promptly replace or restore the portion of the Payment Fund lost through investments or other events so as to ensure that the Payment Fund is maintained at a level sufficient to make such payments. Any interest and other income resulting from such investment (if any) in excess of the amounts payable pursuant to Section 2.6 shall be for the benefit of Parent and promptly returned to Parent.

(b) Promptly after the Effective Time (but in no event later than five (5) business days thereafter), the Surviving Corporation shall cause the Paying Agent to mail or otherwise provide to each Person who was, at the Effective Time, a holder of record of (i) Shares represented by a certificate evidencing such Shares (the “Certificates”) or (ii) Book-Entry Shares, who, in each case was entitled to receive the Merger Consideration pursuant to Section 2.5, (A) a form of letter of transmittal, which shall be in reasonable and customary form and 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 (or effective affidavits of loss in lieu thereof in accordance with Section 2.6(e), if applicable) to the Paying Agent, or a customary agent’s message in respect to Book-Entry Shares, and (B) instructions for use in effecting the surrender of the Certificates or Book-Entry Shares in exchange for the Merger Consideration issuable and payable in respect of such Shares pursuant to Section 2.5. Upon surrender to the Paying Agent of Certificates (or effective affidavits of loss in lieu thereof in accordance with Section 2.6(e), if applicable) or Book-Entry Shares, together with such letter of transmittal in the case of Certificates, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be required pursuant to the instructions, the holder of such Certificates or Book-Entry Shares shall be entitled to receive in exchange therefor the Merger Consideration for each Share formerly evidenced by such Certificates or Book-Entry Shares, and such Certificates and Book-Entry Shares shall then be cancelled. No interest shall 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. If the payment of any Merger Consideration is to be made to a Person other than the Person in whose name the surrendered Certificates formerly evidencing the Shares is registered on the stock transfer books of the Company, it shall be a condition of payment that the Certificate so surrendered shall be endorsed properly or otherwise be in proper form for transfer and that the Person requesting such payment shall have paid all transfer and other similar Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of the Certificate surrendered, or shall have established to the satisfaction of the Surviving Corporation that such Taxes either have been paid or are not required to be paid. None of Parent, Purchaser or the Surviving Corporation shall have any liability for the transfer and other similar Taxes described in this Section 2.6(b) under any circumstance. Payment of the applicable Merger Consideration with respect to Book-Entry Shares shall only be made to the Person in whose name such Book-Entry Shares are registered. Until surrendered as contemplated by this Section 2.6, each Certificate and Book-Entry Share representing Shares that were converted into the right to receive the Merger Consideration shall be deemed at any time after the Effective Time to represent only the right to receive the applicable Merger Consideration as contemplated by Section 2.5.

(c) At any time following six (6) months after the Effective Time, Parent shall be entitled to require the Paying Agent to deliver to it any funds (with respect to the aggregate Merger Consideration to which holders of Shares shall become entitled pursuant to Section 2.5) which had been made available to the Paying Agent and not disbursed to holders of Certificates or Book-Entry Shares (including all interest and other income received by the Paying Agent in respect of all funds made available to it), and, thereafter, such holders shall be entitled to look to the Surviving Corporation (subject to abandoned property, escheat and other similar Legal Requirements) only as general creditors thereof with respect to the Merger Consideration that may be payable upon due surrender of the Certificates or Book-Entry Shares held by them, without any interest thereon. Notwithstanding the foregoing, neither the Surviving Corporation nor the Paying Agent shall be liable to any holder of Certificates or Book-Entry Shares for the Merger Consideration delivered in respect of such Share to a public official pursuant to any abandoned property, escheat or other similar Legal Requirements. Any amounts remaining unclaimed by such holders at such time at which such amounts would otherwise escheat to or become property of any Governmental Body shall become, to the extent permitted by applicable Legal Requirements, the property of the Surviving Corporation or its designee, free and clear of all claims or interest of any Person previously entitled thereto.

(d) At the close of business on the day of the Effective Time, the stock transfer books of the Company with respect to the Shares shall be closed and thereafter there shall be no further registration of transfers of Shares on the records of the Company. From and after the Effective Time, the holders of the Shares outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Shares except as otherwise provided herein or by applicable Legal Requirements.

(e) Notwithstanding any provision contained herein to the contrary, each of the Surviving Corporation, Parent, Purchaser, and the Paying Agent shall be entitled to deduct and withhold from amounts (including any CVR or any Milestone Payment) otherwise payable in connection with this Agreement or the CVR Agreement any amounts as are required to be withheld or deducted with respect to such payment under the Code or any applicable Legal Requirement. To the extent that amounts are so deducted or withheld, such amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction or withholding was made. The payment of any transfer, documentary, sales, use, stamp, registration, value added or other Tax by a holder of Shares in connection with the transactions contemplated by this Agreement, and the filing of any related Tax Return or other documentation with respect to any such Tax, shall be the responsibility of such holder.

(f) If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the holder of the Shares formerly represented by that Certificate, or by a representative of that holder, claiming that Certificate to be lost, stolen or destroyed and, if required by the Surviving Corporation, the posting by that holder of a customary bond, in such reasonable amount as Parent may direct, as indemnity against any claim that may be made against it with respect to such Certificate (which shall not exceed the Merger Consideration payable with respect to such Certificate), the Paying Agent will pay (less any amounts entitled to be deducted or withheld pursuant to Section 2.6(e)), in exchange for such lost, stolen or destroyed Certificate, the applicable Merger Consideration to be paid in respect of the Shares formerly represented by such Certificate, as contemplated by this Section 2.

2.7 Dissenters’ Rights. Notwithstanding anything in this Agreement to the contrary, Shares issued and outstanding as of immediately prior to the Effective Time and held by holders (or held in a voting trust or by a nominee on behalf of a beneficial owner who beneficially owns such Shares) who are entitled to appraisal rights under Section 262 of the DGCL and have properly exercised and demanded appraisal rights of such Shares in the time and manner provided in Section 262 of the DGCL and, as of the Effective Time, have neither effectively withdrawn, validly waived nor otherwise lost their rights to such appraisal and payment under the DGCL (the “Dissenting Shares”), shall not be converted into the right to receive Merger Consideration, but shall, by virtue of the Merger, be automatically cancelled and no longer outstanding, shall cease to exist and shall be entitled to only such consideration as shall be determined pursuant to Section 262 of the DGCL; provided that if any such person shall have failed to perfect or shall have effectively withdrawn, validly waived or otherwise lost such person’s right to appraisal and payment under the DGCL, such Shares shall be deemed to have been converted as of the Effective Time into the right to receive the Merger Consideration (less any amounts entitled to be deducted or withheld pursuant to Section 2.6(e)), and such Shares shall not be deemed to be Dissenting Shares. The Company shall give prompt notice to Parent and Purchaser of any demands received by the Company for appraisal of any Dissenting Shares, withdrawals of such demands and any other instruments served pursuant to Section 262 of the DGCL, in each case prior to the Effective Time. Parent and Purchaser shall have the right to direct and participate in, and after the Effective Time, direct all negotiations and proceedings with respect to such demands. Prior to the Effective Time, the Company shall not, without the prior written consent of Parent and Purchaser, settle or offer to settle, or make any payment with respect to, any such demands, or agree or commit to do any of the foregoing.

(a) At the Effective Time:

(i) each Company Option that is outstanding and unvested as of immediately prior to the Effective Time will vest in full;

(ii) each Tranche 1 Option that is then outstanding will be cancelled, and, in exchange therefor, the holder of such cancelled Tranche 1 Option will be entitled to (A) an amount in cash equal to the product of (x) the total number of Shares subject to such Tranche 1 Option immediately prior to the Effective Time multiplied by (y) the excess of the amount of the Cash Consideration over the applicable exercise price per Share of such Tranche 1 Option, and (B) receive one CVR with respect to each Share subject to such Tranche 1 Option as of immediately prior to the Effective Time;

(iii) each Company Option that is a Tranche 2 Option or Tranche 3 Option that is then outstanding will be cancelled, and, in exchange therefor, the holder of such cancelled Company Option will be entitled to receive one CVR with respect to each Share subject to such Company Option as of immediately prior to the Effective Time (it being understood, for the avoidance of doubt, that the terms applicable to the CVRs received in respect of Tranche 2 Options or Tranche 3 Options differ from those applicable to other CVRs, as set forth in the CVR Agreement); and

(iv) each Company Option other than a Tranche 1 Option, a Tranche 2 Option or a Tranche 3 Option that is then outstanding and unexercised, whether or not vested, shall be cancelled with no consideration payable in respect thereof.

(b) At the Effective Time, each Company RSU that is then outstanding, whether or not vested, shall be cancelled and the holder thereof shall be entitled to (i) an amount in cash equal to the product of (x) the total number of Shares subject to such Company RSU immediately prior to the Effective Time (without regard to vesting) multiplied by (y) the Cash Consideration, and (ii) receive one CVR with respect to each Share subject to such Company RSU as of immediately prior to the Effective Time (without regard to vesting).

(c) Parent shall, or shall cause the Surviving Corporation (or, in the case of consideration payable in connection with a Milestone Payment pursuant to a CVR, either the Rights Agent or the Surviving Corporation or an Affiliate pursuant to a Self-Pay Election (as defined in the CVR Agreement)) to, pay the aggregate consideration payable pursuant to this Section 2.8, net of any applicable withholding Taxes or other deductions (which amounts may be paid to current and former employees of the Company through Parent’s or the Surviving Corporation’s or an Affiliate’s payroll system or any successor payroll system (in the case of Milestone Payments under the CVR Agreement, if so determined by the Parent pursuant to a Self-Pay Election)) (i) in the case of any such consideration payable pursuant to Section 2.8(a)(ii)(A) or Section 2.8(b)(i), as promptly as practicable (and in any event no later than the third payroll date) after the Effective Time or (ii) in the case of any such consideration payable in connection with a Milestone Payment, as promptly as practicable after such Milestone Payment becomes due and payable under the CVR Agreement; provided that any such amounts that constitute nonqualified deferred compensation subject to Section 409A of the Code shall be paid at the earliest time permitted under the terms of the applicable award that would not result in a tax or penalty under Section 409A of the Code. Without limiting the generality of the foregoing, any payment made pursuant to Section 2.8(a) with respect to a Company Option that is an incentive stock option (within the meaning of Section 422 of the Code) shall be subject to Tax reporting and withholding in accordance with applicable Legal Requirements. Prior to the Effective Time, the Company shall take all actions appropriate or necessary (under the Company Equity Plans and award agreements pursuant to which Company Options and Company RSUs are outstanding or otherwise) to effect the transactions described in this Section 2.8, so that as of the Effective Time there are no obligations in respect of the Company Options or Company RSUs other than the right to receive the payments under this Section 2.8.

2.9 Further Action. If no Offer Termination has occurred, the Parties agree to take all necessary action to cause the Merger to become effective in accordance with this Section 2 as soon as practicable following the consummation of the Offer without a meeting of the Company’s stockholders, as provided in Section 251(h) of the DGCL. If, at any time after the Effective Time, any further action is reasonably determined by Parent to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full right, title and possession of and to all rights and property of Purchaser and the Company, the officers and directors of the Surviving Corporation and Parent shall be fully authorized (in the name of Purchaser, in the name of the Company and otherwise) to take such action.

Prior to the Effective Time, each of Parent and the Company shall exercise, consistent with the terms and conditions hereof, complete control and supervision of its and its, if applicable, Subsidiaries’ respective operations.

5.3 No Solicitation.

(a) For the purposes of this Agreement, “Acceptable Confidentiality Agreement” means any customary confidentiality agreement that (i) contains provisions that are not less favorable in any material respect to the Company than those contained in the Confidentiality Agreement and (ii) does not prohibit the Company from providing any information to Parent in accordance with, and otherwise complying with, this Agreement.

(b) The Acquired Corporations shall, and cause their Representatives to, immediately cease any solicitation, knowing encouragement, discussions or negotiations with any Persons that may be ongoing with respect to an Acquisition Proposal as of the date hereof. Except as otherwise expressly permitted by this Section 5.3(b), during the Pre-Closing Period the Acquired Corporations shall not, and shall cause their Representatives not to, directly or indirectly, (i) continue any solicitation, knowing encouragement, discussions or negotiations with any Persons that may be ongoing with respect to an Acquisition Proposal as of the date hereof; (ii) (A)

solicit, initiate or facilitate or knowingly encourage (including by way of furnishing non-public information) any inquiries regarding, or the making of any proposal or offer that constitutes, or could reasonably be expected to lead to, an Acquisition Proposal, (B) engage in, continue or otherwise participate in any discussions or negotiations regarding, or furnish to any other Person any non-public information in connection with, or for the purpose of soliciting or knowingly encouraging or facilitating, an Acquisition Proposal or any proposal or offer that could reasonably be expected to lead to an Acquisition Proposal, (C) enter into any letter of intent, acquisition agreement, agreement in principle or similar agreement with respect to an Acquisition Proposal or any proposal or offer that could reasonably be expected to lead to an Acquisition Proposal or (D) take any action to exempt any Person (other than Parent and its Subsidiaries) from the restrictions on “business combinations” or any similar provision contained in applicable Takeover Laws or the Company’s organizational and other governing documents; (iii) waive or release any Person from, forebear in the enforcement of, or amend any standstill agreement or any standstill provisions of any other Contract, unless, solely in the case of this clause (iii), (I) the Board of Directors determines in good faith, after consultation with the Company’s outside legal counsel, that the failure to do so would be inconsistent with the fiduciary duties of the Board of Directors to the Company’s stockholders under applicable Legal Requirements, in which event the Acquired Corporations may take the actions described in this clause (iii) solely to the extent necessary to permit a third party to make, on a confidential basis to the Board of Directors, an Acquisition Proposal, conditioned upon such third party agreeing that the Company shall not be prohibited from providing any information to Parent (including regarding any such Acquisition Proposal) in accordance with, and otherwise complying with, this Section 5.3 and (II) the Company complies with the obligations set forth in Section 5.3(d) or (iv) resolve or agree to do any of the foregoing. As promptly as reasonably practicable (and in any event within two (2) business days) following the date hereof, the Company shall request the prompt return or destruction (to the extent provided for by the applicable confidentiality agreement) of all non-public information previously furnished to any Person (other than Parent) that has, within the one (1)-year period prior to the date of this Agreement, made or indicated an intention to make an Acquisition Proposal and the Company shall, and shall cause the other Acquired Corporations to, within one (1) business day following the date hereof, terminate access by any third Person who has made or would reasonably be expected to make an Acquisition Proposal (other than Parent and its Representatives) to any data room (virtual or actual) containing any confidential information of any Acquired Corporation.

(c) If at any time on or after the date of this Agreement and prior to the Offer Acceptance Time or the receipt of the Company Stockholder Approval (whichever is first to occur, the “Cut-off Time”) any Acquired Corporation or any of their Representatives receives an unsolicited bona fide written Acquisition Proposal from any Person or group of Persons, which Acquisition Proposal was made or renewed on or after the date of this Agreement and did not result from or arise out of a breach of this Section 5.3 or Section 6.1, if the Board of Directors determines in good faith, (i) after consultation with the Company’s financial advisors and outside legal counsel, that such Acquisition Proposal constitutes or would reasonably be expected to lead to a Superior Offer, and (ii) after consultation with the Company’s outside legal counsel, that the failure to take such action described in clauses (A) and (B) of this Section 5.3(c) would be inconsistent with the fiduciary duties of the Board of Directors to the Company’s stockholders under applicable Legal Requirements, then the Company and its Representatives may (A) furnish, pursuant to an Acceptable Confidentiality Agreement, information (including non-public information) with

respect to the Acquired Corporations to the Person or group of Persons who has made such Acquisition Proposal and their Representatives; provided that the Company shall substantially concurrently provide to Parent any information concerning the Acquired Corporations that is provided to any Person to the extent access to such information was not previously provided to Parent or its Representatives and (B) engage in or otherwise participate in discussions or negotiations with the Person or group of Persons making such Acquisition Proposal. The Company shall provide Parent with an accurate and complete copy of any Acceptable Confidentiality Agreement entered into as contemplated by this Section 5.3 promptly (and in any event within one (1) day) of the execution thereof.

(e) Nothing in this Section 5.3 or elsewhere in this Agreement shall prohibit the Company or the Board of Directors from (i) taking and disclosing to the stockholders of the Company a position contemplated by Rule 14e-2(a), Rule 14d-9 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act, including any “stop, look and listen” communication pursuant to Rule 14d-9(f) promulgated under the Exchange Act, or (ii) making any disclosure to the stockholders of the Company if the Board of Directors determines, in good faith, after consultation with outside counsel, that the failure to take such action would be inconsistent with its fiduciary duties under applicable Legal Requirements; provided, that this Section 5.3(e) shall not be deemed to permit the Board of Directors to make a Company Adverse Recommendation Change except to the extent permitted by Section 6.1(b).

(f) The Company agrees that in the event any Acquired Corporation or any Representative of an Acquired Corporation takes any action which, if taken by the Company, would constitute a breach of this Section 5.3, the Company shall be deemed to be in breach of this Section 5.3.

(a) Within ten (10) business days following receipt by Parent of a request for additional information and documentary materials pursuant to 15 USC §18a(e)(1)(A), Parent may, after consulting with and considering in good faith the views of the Company, by providing written notice to the Company (a “Meeting Election”), require the Company to, as promptly as reasonably practicable (and in any event within fifteen (15) days) after a Meeting Election, prepare and file with the SEC a proxy statement in preliminary form related to the Company Stockholder Meeting (together with any amendments thereof or supplements thereto, the “Merger Proxy Statement”); provided that if an HSR Filing has been made pursuant to Section 6.2(b), the waiting period (and any extension thereof) applicable to the Offer or the Merger under the HSR Act shall have expired or been terminated, (i) Parent may not deliver a Meeting Election and (ii) if a Meeting Election has already been delivered but the Company has not yet mailed the Merger Proxy Statement, the Meeting Election and any Offer Termination shall automatically be withdrawn and, if the Offer has been terminated or expired without any Shares having been accepted for payment, Purchaser shall recommence the Offer. The Company shall give Parent and its counsel reasonable opportunity to review and comment on the initial preliminary Merger Proxy Statement and all subsequent forms or versions of or amendments or supplements to the Merger Proxy Statement prior to the filing thereof with the SEC or dissemination to the holders of Shares and the Company shall give reasonable and good faith consideration to any timely comments thereon made by the other Party or its counsel. Parent and Purchaser shall promptly supply to the Company in writing, for inclusion in the Merger Proxy Statement, all information concerning Parent and Purchaser and their Affiliates required under applicable Legal Requirements to be included in the Merger Proxy Statement as is reasonably requested by the Company. Parent, Purchaser and the Company shall cooperate in good faith to determine the information regarding each of them that is necessary to include in the Merger Proxy Statement in order to satisfy applicable Legal Requirements. The Company agrees that the Merger Proxy Statement filed by the Company with the SEC (x) shall comply in all material respects with the Exchange Act and other applicable Legal Requirements and (y) shall not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that no covenant is made by the Company with respect to information supplied by or on behalf of Parent or Purchaser for inclusion or incorporation by reference in the Merger Proxy Statement. Each of Parent, Purchaser and the Company agrees to respond promptly to any comments of the SEC or its staff and to promptly correct any information provided by it for use in the Merger Proxy Statement if and to the extent that such information shall have become false or misleading in any material respect, and the Company further agrees to take all steps necessary to cause the Merger Proxy Statement as so corrected to be filed with the SEC and to be disseminated to holders of Shares, in each case as and to the extent required by applicable Legal Requirements. The Company shall (A) promptly notify Parent of the receipt of, and promptly provide Parent copies of, all comments from, and all correspondence with, the SEC or its staff with respect to the Merger Proxy Statement and shall promptly notify Parent of any request by the SEC or its staff for any amendment or supplement thereto or for additional information, (B) provide Parent and its counsel with a reasonable opportunity to review and comment on any proposed correspondence between it and/or any of its Representatives on the one hand and the SEC or its staff on the other hand with respect to the Merger Proxy Statement and shall give reasonable and good faith consideration to any timely comments thereon made by Parent or its counsel and (C) promptly provide Parent with final copies of any correspondence sent by it and/or any of its Representatives to the SEC or its staff with respect to the Merger Proxy Statement, and of any amendments or supplements to the Merger Proxy Statement. The Merger Proxy Statement shall include the Company Board Recommendation, unless the Board of Directors has made a Company Adverse Recommendation Change in accordance with Section 6.1. The Merger Proxy Statement shall include the notice of the Company Stockholder Meeting and the notice and other information required by Section 262(d) of the DGCL.

(b) Subject to applicable Legal Requirements, if Parent delivers a Meeting Election as provided in clause (a), (i) the Company shall, within four (4) business days of receipt of such Meeting Election, establish a record date consented to by Parent (such consent not to be unreasonably withheld, conditioned or delayed), which date shall be selected so as to permit the Merger Proxy Statement to be mailed, and a meeting of the Company’s stockholders to be held, as soon as reasonably practicable after the filing of the Merger Proxy Statement, for the purpose of voting upon the adoption of this Agreement (together with any adjournments or postponements thereof, the “Company Stockholder Meeting”) and (ii) as soon as reasonably practicable, mail to the holders of Shares as of the record date established for the Company Stockholders Meeting the definitive Merger Proxy Statement. The Company shall duly call, convene and hold the Company Stockholder Meeting as soon as reasonably practicable (but in any event no more than twenty-five (25) business days) following the date the Merger Proxy Statement is mailed to the Company’s stockholders and any adjournments or postponements of such meetings shall require the prior written consent of Parent other than to the extent necessary to allow reasonable additional time for the filing and/or mailing, and review by the Company’s stockholders prior to the date of the Company Stockholder Meeting, of any supplemental or amended disclosure that the Board of Directors determines in good faith is required by applicable Legal Requirements or the rules and regulations of NASDAQ. Notwithstanding the foregoing, the Company may (without the consent of Parent), and Parent may require the Company to, adjourn or postpone the Company Stockholder Meeting two (2) times (for a period of not more than 10 business days each but not past three (3) business days prior to the End Date), unless prior to such adjournment or postponement the Company shall have received an aggregate number of proxies voting for the adoption of this Agreement, which have not been withdrawn, such that the condition in Section 7.1(a) would be satisfied at such meeting if it were to be held without such postponement or adjournment. Once the Company has established a record date for the Company Stockholder Meeting, the Company shall not change such record date or establish a different record date for the Company Stockholder Meeting without the prior written consent of Parent, unless required to do so by applicable Legal Requirements. Unless the Board of Directors shall have made a Company Adverse Recommendation Change in compliance with Section 6.1, the Company shall use reasonable best efforts to obtain the Company Stockholder Approval, including to solicit proxies in favor of the adoption of this Agreement. Unless this Agreement is validly terminated in accordance with Section 8.1, the Company shall submit this Agreement to its stockholders at the Company Stockholder Meeting even if the Board of Directors shall have made a Company Adverse Recommendation Change or proposed or announced any intention to do so. The Company shall, upon the reasonable request of Parent, advise Parent at least on a daily basis on each of the last seven (7) business days prior to the date of the Company Stockholder Meeting as to the aggregate tally of proxies received by the Company with respect to the Company Stockholder Approval. Without the prior written consent of Parent, the adoption of this Agreement and customary annual meeting matters (if applicable) shall be the only matters (other than related procedural matters) that the Company shall propose to be acted on by the stockholders of the Company at the Company Stockholder Meeting. The foregoing notwithstanding, the Company shall not set a record date, mail a proxy statement with respect to, or convene the Company Stockholder Meeting unless Parent shall have made a Meeting Election.

Without limiting the foregoing, during the period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time, Parent shall cause the Surviving Corporation and the other Acquired Corporations to, and the Surviving Corporation agrees that it will, indemnify and hold harmless each individual who is as of the date of this Agreement, or who becomes prior to the Effective Time, a director or officer of any Acquired Corporation or who is as of the date of this Agreement, or who thereafter commences prior to the Effective Time, serving at the request of any Acquired Corporation as a director or officer of another Person (the “Indemnified Persons”), against all claims, losses, liabilities, damages, judgments, inquiries, fines and reasonable fees, costs and expenses, including attorneys’ fees and disbursements, incurred in connection with any claim, action, suit or proceeding, whether civil, criminal, administrative or investigative (including with respect to matters existing or occurring at or prior to the Effective Time, including this Agreement and the transactions and actions contemplated hereby), arising out of or pertaining to, or by reason of, the fact that the Indemnified Person is or was a director or officer of any Acquired Corporation or is or was serving at the request of any Acquired Corporation as a director or officer of another Person, whether asserted or claimed prior to, at or after the Effective Time, to the fullest extent

To the fullest extent permitted under applicable Legal Requirements, Parent shall cause the Surviving Corporation and the other Acquired Corporations to pay, in advance, all reasonable attorneys’ fees and expenses that may be incurred by Indemnified Persons in connection with their enforcement of their rights provided under this Section 6.5, provided that any Indemnified Person to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined by a final non-appealable adjudication that such Indemnified Person is not entitled to indemnification.

(b) Parent shall arrange to be bound at Closing a six (6)-year prepaid “tail” directors’ and officers’, employment practices and fiduciary liability insurance policy or policies for the Acquired Corporations and their current and former directors and officers who are currently covered by the directors’ and officers’, employment practices and fiduciary liability insurance coverage currently maintained by or for the benefit of the Acquired Corporations, such tails to provide coverage in an amount not less than the existing coverage and to have other terms not less favorable in the aggregate to the insured persons than the directors’ and officers’, employment practices and fiduciary liability insurance coverage currently maintained by or for the benefit of the Acquired Corporations with respect to claims arising from acts or omissions that occurred at or before the Effective Time and covering, without limitation, the Transactions; provided that in no event shall the cost of any such tail policy or policies exceed 300% of the aggregate annual premium most recently paid by the Acquired Corporations prior to the date of this Agreement with respect to each such coverage (the “Maximum Amount”); provided further that arranging for such insurance shall not require Parent to undertake any commitment prior to the Closing to pay any fees. If the aggregate premiums of any such tail insurance coverage exceeds the Maximum Amount, then Parent may obtain a policy or policies with the greatest coverage available for a cost not exceeding the Maximum Amount. Parent and the Surviving Corporation shall maintain all such tail policies in full force and effect, and continue to honor the obligations thereunder.

Unless required by applicable Legal Requirement, neither this Section 6.5, nor the indemnification, exculpation or advancement provisions of any organizational documents of any Acquired Corporation in effect on the date of this Agreement, may be amended, altered or repealed after the Offer Acceptance Time in such a manner as to adversely affect the rights of any Indemnified Person or any of their successors, assigns or heirs without the prior written consent of the affected Indemnified Person. The Indemnified Persons to whom this Section 6.5 applies shall be third party beneficiaries of this Section 6.5.

The Company shall give Parent the right to review and comment on all material filings or responses to be made by the Company in connection with any Transaction Litigation against the Company and/or its directors or officers relating to the Transactions, and the right to consult on any settlement with respect to such litigation, and the Company shall in good faith take such consultation into account (to the extent that the attorney-client privilege is not lost as a result thereof). Prior to Closing, no such settlement shall be agreed to without Parent’s prior written consent (provided, however, that, with respect to any such settlement prior to Closing that only requires payment of monetary amounts by the Company that do not exceed in the aggregate the amount set forth on Section 6.6 of the Company Disclosure Schedule, such consent shall not be unreasonably withheld, conditioned or delayed). The Company shall promptly notify Parent of any such litigation and shall keep Parent reasonably and promptly informed with respect to the status thereof.

(j) by the Company, (i) if Purchaser shall have failed to commence (within the meaning of Rule 14d-2 under the Exchange Act) the Offer within the period specified in Section 1.1(a) without the prior written consent of the Company or (ii) except if an Offer Termination has occurred, if Purchaser shall have failed to accept for payment all Shares validly tendered (and not validly withdrawn) pursuant to the Offer within the period specified in Section 1.1(h).

MISCELLANEOUS PROVISIONS

9.1 Amendment. Prior to the Effective Time, whether before or after the Company Stockholder Approval shall have been obtained, this Agreement may be amended with the approval of each of Parent and Purchaser and the Board of Directors at any time; provided, if applicable, that following receipt of the Company Stockholder Approval no amendment may be made which under applicable Legal Requirements requires further stockholder approval without obtaining such approval. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the Parties.

9.2 Waiver. No failure on the part of any Party to exercise any power, right, privilege or remedy under this Agreement, and no delay on the part of any Party in exercising any power, right, privilege or remedy under this Agreement, shall operate as a waiver of such power, right, privilege or remedy; and no single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy. At any time prior to the Effective Time, Parent and Purchaser, on the one hand, and the Company, on the other hand, may (a) extend the time for the performance of any of the obligations or other acts of the other, (b) waive any breach of the representations and warranties of the other contained herein or in any document delivered pursuant hereto or (c) waive compliance by the other with any of the agreements or covenants contained herein. Any such extension or waiver shall be valid only if is expressly set forth in a written instrument duly executed and delivered on behalf of the Party or Parties to be bound thereby, but such extension or waiver or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

9.3 No Survival of Representations and Warranties. None of the representations and warranties contained in this Agreement, the Company Disclosure Schedule or in any certificate or schedule or other document delivered by any Person pursuant to this Agreement shall survive the Merger. This Section 9.3 shall not limit any covenant or agreement contained in this Agreement which by its terms contemplates performance after the Effective Time.

9.4 Entire Agreement; Counterparts. This Agreement (including its Exhibits, Annexes and the Company Disclosure Schedule) and the Confidentiality Agreement constitute the entire agreement and supersede all prior agreements and understandings, both written and oral, among or between any of the Parties and their respective Affiliates, with respect to the subject matter hereof and thereof. This Agreement may be executed in one or more counterparts, including by facsimile or by email with .pdf attachments, all of which shall be considered one and the same agreement, and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties.

9.5 Applicable Legal Requirements; Jurisdiction; Specific Performance; Remedies.

(a) This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws thereof. In any action or proceeding arising out of or relating to this Agreement or any of the Transactions: (i) each of the Parties irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Chancery Court of the State of Delaware and any state appellate court therefrom or, if (but only if) such court lacks subject matter jurisdiction, the United States District Court sitting in New Castle County in the State of Delaware and any appellate court therefrom (collectively, the “Delaware Courts”); and (ii) each of the Parties irrevocably consents to service of process by first class certified mail, return receipt requested, postage prepaid, to the address at which such Party is to receive notice in accordance with Section 9.8; provided that nothing in this Section 9.5(a) shall affect the right of any Party to serve legal process in any other manner permitted by applicable Legal Requirements. Each of the Parties irrevocably and unconditionally (1) agrees not to commence any such action or proceeding except in the Delaware Courts, (2) agrees that any claim in respect of any such action or proceeding may be heard and determined in the Delaware Courts, (3) waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the jurisdiction or laying of venue of any such action or proceeding in the Delaware Courts and (4) waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in the Delaware Courts. The Parties agree that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Legal Requirements; provided, however, that nothing in the foregoing shall restrict any Party’s rights to seek any post-judgment relief regarding, or any appeal from, such final trial court judgment.

(b) The Parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that the Parties do not perform their obligations under the provisions of this Agreement in accordance with its specified terms or otherwise breach such provisions. The Parties acknowledge and agree that (i) the Parties shall be entitled to an injunction or injunctions, specific performance, or other equitable relief, to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in the courts described in Section 9.5(a) without proof of damages or otherwise, this being in addition to any other remedy to which they are entitled under this Agreement, and (ii) the right of specific performance is an integral part of the Transactions and without that right, neither the Company nor Parent would have entered into this Agreement. The right to specific performance hereunder shall include the right of each of the Parties to cause the other Parties to cause the Offer, the Merger and the other Transactions to be consummated on the terms and subject to the conditions set forth in this Agreement. Each of the Parties agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief on the basis that the other Parties have an adequate remedy at law or an award of specific performance is not an appropriate remedy for any reason at law or equity. The Parties acknowledge and agree that any Party seeking an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in accordance with this Section 9.5(b) shall not be required to provide any bond or other security in connection with any such order or injunction.

(c) The Parties acknowledge and agree that time is of the essence and that the Parties would suffer ongoing irreparable injury for so long as any provision of this Agreement is not performed in accordance with its specific terms (but subject to any time period allotted for such performance by such terms). It is accordingly agreed that, as to any Legal Proceedings in which a Party seeks specific performance or other equitable relief pursuant to Section 9.5(b), the Parties shall use their commercially reasonable efforts to seek an expedited schedule for such proceedings and shall not oppose any Party’s request for expedited proceedings.

(d) EACH OF THE PARTIES IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING BETWEEN THE PARTIES (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE), INCLUDING ANY COUNTERCLAIM, ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THE ACTIONS OF ANY PARTY HERETO IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT THEREOF. EACH PARTY (I) MAKES THIS WAIVER VOLUNTARILY AND (II) ACKNOWLEDGES THAT SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS CONTAINED IN THIS SECTION 9.5(d).

9.6 Assignability. This Agreement shall be binding upon, and shall be enforceable by and inure solely to the benefit of, the Parties and their respective successors and permitted assigns; provided, however, that neither this Agreement nor any of the rights hereunder may be assigned by a Party without the prior written consent of the other Parties, and any attempted assignment of this Agreement or any of such rights without such consent shall be void and of no effect; provided, further, however, that Parent or Purchaser may assign this Agreement to any of Parent’s controlled Affiliates (provided that such assignment by Parent shall not relieve Parent or Purchaser of its obligations hereunder or otherwise alter or change any obligation of any other Party hereto and no such assignment shall be permitted to the extent it would reasonably be expected to delay the Closing).

9.7 No Third Party Beneficiaries. Nothing in this Agreement, express or implied, is intended to or shall confer upon any Person (other than the Parties) any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement; except for: (a) if the Offer Acceptance Time occurs, (i) the right of the Company’s stockholders to receive the Offer Consideration or Merger Consideration, as applicable, pursuant to Section 1 or Section 2 following the Offer Acceptance Time or the Effective Time, as applicable, in accordance with the terms of this Agreement, and (ii) the right of the holders of Company Options and Company RSUs to receive the applicable payments pursuant to Section 2.8 following the Effective Time in accordance with the terms of this Agreement; (b) the rights under Section 6.5 of Indemnified Persons to whom Section 6.5 applies; and (c) the limitations on liability of the Company Related Parties set forth in Section 8.3(d).
