Item 1.01 Entry into a Material Definitive Agreement.

On March 12, 2023, Seagen Inc., a Delaware corporation (the “Company”), entered into (i) an Agreement and Plan of Merger (the “Merger Agreement”), by and among the Company, Pfizer Inc., a Delaware corporation (“Pfizer”), and Aris Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Pfizer (“Merger Sub”), pursuant to which, among other things, Merger Sub will be merged with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of Pfizer (the “Surviving Corporation”), and (ii) a Voting Agreement (the “Voting Agreement”), by and among the Company, Pfizer, and Baker Bros. Advisors LP (the “Advisor”), on behalf of itself and certain specified persons identified therein in their respective capacities as record or beneficial owners of Common Shares (as defined below), pursuant to which, among other things, the Advisor has agreed, on the terms and subject to the conditions set forth in the Voting Agreement, to vote (or cause to be voted) all of the Covered Shares (as defined below) in favor of the adoption of the Merger Agreement.

The Merger Agreement

On the terms and subject to the conditions set forth in the Merger Agreement, at the effective time of the Merger (the “Effective Time”), (i) all shares of common stock of the Company, par value $0.001 per share (the “Common Shares”), that are owned by the Company as treasury shares and any Common Shares owned by Pfizer or Merger Sub will automatically be cancelled and extinguished and will cease to exist, and no consideration will be payable in exchange therefor, (ii) each Common Share that is owned by any direct or indirect wholly owned subsidiary of Pfizer (other than Merger Sub) or the Company will be converted into such number of shares of the Surviving Corporation so as to maintain relative ownership percentage, and (iii) each Common Share issued and outstanding immediately prior to the Effective Time (other than Common Shares to be cancelled or converted as described in clauses (i) and (ii) and any Common Shares outstanding immediately prior to the Effective Time and held by a holder of Common Shares who has complied with Section 262 of the General Corporation Law of the State of Delaware with respect to such Common Shares) will be converted into the right to receive an amount in cash equal to $229.00 (the “Merger Consideration”).

In addition, the Merger Agreement provides for the following treatment of the Company’s equity awards at the Effective Time:

• Each option to purchase Common Shares (each a “Company Option”) that is outstanding as of immediately prior to the Effective Time, whether or not then vested, will be cancelled and converted into the right to receive an amount in cash equal to the product of (i) the excess, if any, of the Merger Consideration over the per-share exercise price of such Company Option, multiplied by (ii) the number of Common Shares then subject to such Company Option (which number, in the case of Company Options subject to performance goals based on stock price hurdles, will be determined based on actual performance in accordance with the terms of such Company Options, with any Company Options that do not vest being forfeited for no consideration), net of applicable taxes and without interest.

• Each restricted stock unit (each a “Company RSU”), other than any Post-Signing Company RSU (as defined below), that is outstanding as of immediately prior to the Effective Time, whether or not then vested, will be cancelled and converted into the right to receive an amount in cash in respect thereof equal to the product of (i) the Merger Consideration, multiplied by (ii) the number of Common Shares then subject to such Company RSU, net of applicable taxes and without interest.

• Each Company RSU granted after the date of the Merger Agreement that is unvested and outstanding as of the Effective Time (a “Post-Signing Company RSU”) will be substituted automatically with a Pfizer cash-based award (each, a “Pfizer Cash Award”) with respect to an amount in cash equal to the product of (i) the Merger Consideration, multiplied by (ii) the number of Common Shares then subject to such Post-Signing Company RSU. Each Pfizer Cash Award will otherwise be subject to substantially the same terms and conditions applicable to such Post-Signing Company RSU as of immediately prior to the Effective Time.

• Each Company Non-Products PSU (as defined in the Merger Agreement) that is outstanding immediately prior to the Effective Time, whether or not then vested, will be cancelled and converted into the right to receive an amount in cash equal to the product of (i) the Merger Consideration, multiplied by (ii) the number of Common Shares then subject to such Company Non-Products PSU based on (A) for performance periods that are complete as of the Effective Time, actual performance and (B) for performance periods that are incomplete as of the Effective Time, the greater of the target and actual performance net of applicable taxes and without interest.

• Each Company Products PSU (as defined in the Merger Agreement), that is unvested and outstanding immediately prior to the Effective Time will be substituted automatically with a Pfizer Cash Award subject to the same performance-based vesting requirements (a “Pfizer Performance Cash Award”) with respect to that number of shares of Pfizer Common Stock that is equal to the product of (i) the Merger Consideration, multiplied by (ii) the number of Common Shares then subject to such Company Products PSU. Each Pfizer Performance Cash Award will otherwise be subject to the same terms and conditions applicable to such Company PSU as of immediately prior to the Effective Time; provided, that upon a termination without “cause” (as defined in the Company’s Amended and Restated 2007 Equity Incentive Plan and the Company ESPP), due to death or disability, or for good reason, such Pfizer Performance Cash Award will vest in full.

The consummation of the Merger is subject to various conditions, including, among others, customary conditions relating to : (i) the adoption of the Merger Agreement by the holders of a majority of the outstanding Common Shares entitled to vote on such matter at the meeting of the Company’s stockholders held for that purpose (the “Company Requisite Vote”), (ii) the expiration or earlier termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and receipt of certain non-U.S. antitrust and foreign direct investment approvals, (iii) no statute, rule or regulation that prohibits the consummation of the Merger having been enacted, issued, enforced or promulgated and remaining in effect in certain specified jurisdictions, and no order or injunction of a court of competent jurisdiction being in effect in certain specified jurisdictions that prohibits or makes illegal the consummation of the Merger and (iv) no Company Material Adverse Effect (as defined in the Merger Agreement) having occurred since the date of the Merger Agreement that is continuing. The obligations of each party to effect the Merger are also conditioned on the accuracy of the other party’s representations and warranties (subject to certain materiality exceptions) and the other party’s performance and compliance with, in all material respects, the agreements, obligations and covenants required to be performed by it under the Merger Agreement at or prior to the Effective Time.

The Merger Agreement also contains customary representations, warranties and covenants of the Company, Pfizer and Merger Sub, including covenants regarding the operation of the business of the Company and its subsidiaries prior to the Effective Time. In addition, the Company has agreed to customary “no-shop” restrictions on the Company’s ability to solicit any Company Acquisition Proposal (as defined in the Merger Agreement), to enter into any Alternative Acquisition Agreement (as defined in the Merger Agreement), and to participate in discussions or negotiations with or provide non-public information to any person relating to any Company Acquisition Proposal. Notwithstanding the limitations applicable under the “no-shop” restrictions, if, after the date of the Merger Agreement and prior to the date on which the Company Requisite Vote is obtained, the Company receives a bona fide proposal relating to a Company Acquisition Proposal that did not result from a material breach of the Company’s obligations under the “no-shop” restrictions and the Company Board of Directors (the “Board”) determines in good faith, after consultation with its financial advisors, that such Company Acquisition Proposal either constitutes or could reasonably be expected to lead to a Superior Proposal (as defined in the Merger Agreement), the Company may furnish non-public information to the person making such Company Acquisition Proposal in accordance with a confidentiality agreement not materially less favorable in the aggregate than the confidentiality agreement between the Company and Pfizer and may participate in discussions and negotiations with such person, subject to certain notice rights and match rights in favor of Pfizer.

The Merger Agreement provides for certain customary termination rights of the Company and Pfizer, including the Company’s right, subject to certain limitations, to terminate the Merger Agreement in certain circumstances to accept a Superior Proposal, Pfizer’s right to terminate the Merger Agreement if the Board changes its recommendation that the Company’s stockholders approve the adoption of the Merger Agreement, and the right of either party to terminate the Merger Agreement if the Merger has not been completed on or prior to 5:00 p.m. (New York Time) on March 12, 2024 (as may be extended under the Merger Agreement, the “Outside Date”), which will be automatically extended to September 12, 2024 if certain regulatory closing conditions remain the only conditions not satisfied or waived as of March 12, 2024 (other than conditions that by their terms are to be satisfied at the closing). The Merger Agreement also provides that the Company will be required to pay Pfizer a termination fee of $1.646 billion following or in connection with the termination of the Merger Agreement in certain circumstances, including if the Company terminates the Merger Agreement in order to accept a Superior Proposal as set forth in the Merger Agreement.

In addition, the Merger Agreement provides that Pfizer will be required to pay the Company a termination fee of $2.224 billion in connection with the termination of the Merger Agreement, subject to certain limitations set forth in the Merger Agreement, if the Merger Agreement is terminated by either party as a result of (i) certain regulatory closing conditions relating to antitrust laws and foreign direct investment laws not having been satisfied as of the Outside Date or (ii) a court of competent jurisdiction or other governmental authority having issued a final, non-appealable order, or a statute, rule or regulation being in place, in each case, in connection with any antitrust law or foreign direct investment law, that permanently restrains, enjoins or otherwise prohibits the consummation of the Merger.

The Voting Agreement

Accordingly, the representations, warranties, and covenants or any descriptions thereof should not be relied upon by any person as characterizations of the actual state of facts or condition of the parties thereto or any of their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of representations and warranties may change after the date of the Voting Agreement, which subsequent information will not necessarily be fully reflected in the Company’s or Pfizer’s public disclosures.

WHEREAS, the Company, Parent and Merger Sub desire to make certain representations, warranties, covenants and agreements in connection with the Merger and the other transactions contemplated hereby.

NOW, THEREFORE, the parties hereto hereby agree as follows:

SECTION 1 - THE MERGER

1.1 The Merger.

(a) On the terms and subject to the conditions of this Agreement, the Company and Merger Sub will consummate the Merger in accordance with the DGCL, such that, at the Effective Time, (i) Merger Sub will be merged with and into the Company, and the separate corporate existence of Merger Sub will thereupon cease, (ii) the Company will be the successor or surviving corporation in the Merger and will continue to be governed by the Laws of the State of Delaware, (iii) the corporate existence of the Company with all its rights, privileges, immunities, powers, objects and purposes will continue and (iv) the Company will automatically assume all the rights and obligations of Merger Sub. The corporation surviving the Merger is sometimes referred to as the “Surviving Corporation.” The Merger will have the effects set forth in the applicable provisions of the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all the rights, privileges, immunities, powers, objects and purposes of the Company and Merger Sub will be vested in the Surviving Corporation, and all claims, debts, liabilities and obligations of the Company and Merger Sub will be the claims, debts, liabilities and obligations of the Surviving Corporation.

(b) At the Effective Time, the certificate of incorporation of the Company will, by virtue of the Merger, be amended and restated in its entirety to be as set forth in Annex II and, as so amended, will be the certificate of incorporation of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable Law. The name of the Surviving Corporation will be “Seagen Inc.”

(c) At the Effective Time, and without any further action on the part of the Company or Merger Sub, the bylaws of the Company will be amended and restated in their entirety to be identical to the bylaws of Merger Sub as in effect immediately prior to the Effective Time, except that all references therein to Merger Sub will be deemed to be references to the Surviving Corporation, and, as so amended, will be the bylaws of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable Law.

1.2 Effective Time. Parent, Merger Sub and the Company will cause a certificate of merger (the “Certificate of Merger”) to be executed and filed on the Closing Date (or on such other date as Parent and the Company may agree) with the Secretary of State of the State of Delaware as provided in the DGCL.

1.3 The Closing. On the terms and subject to the conditions of this Agreement and in accordance with the DGCL, the closing of the Merger (the “Closing”) will occur at 9:00 a.m. (New York time) on the third Business Day after the satisfaction or waiver (to the extent permitted by applicable Law) of all of the conditions set forth in Section 7 (other than such conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of such conditions at or prior to the Closing) (the date on which the Closing occurs, the “Closing Date”), by electronic exchange of deliverables, unless another date, time or place is agreed to in writing by the parties hereto.

1.4 Directors and Officers of the Corporation. The directors of Merger Sub immediately prior to the Effective Time will, from and after the Effective Time, be the directors of the Surviving Corporation, and the officers of the Merger Sub immediately prior to the Effective Time will, from and after the Effective Time, be the officers of the Surviving Corporation, in each case, until their respective successors have been duly elected, designated or qualified, or until their earlier death, disqualification, resignation or removal in accordance with the Surviving Corporation’s certificate of incorporation and bylaws.

SECTION 2 - CONVERSION OF SECURITIES

2.1 Conversion of Shares. As of the Effective Time, by virtue of the Merger and without any action on the part of the holders of any shares of common stock of the Company, par value $0.001 per share (the “Common Shares”), or any shares of common stock of Merger Sub, $0.01 per share (“Merger Sub Common Shares”):

(a) Merger Sub Common Shares. Each issued and outstanding Merger Sub Common Share will be converted into and become one fully paid and nonassessable share of common stock of the Surviving Corporation.

(b) Cancellation of Treasury Shares and Parent-Owned Shares. All Common Shares that are owned by the Company as treasury shares and any Common Shares owned by Parent or Merger Sub will automatically be cancelled and extinguished and will cease to exist, and no consideration will be payable in exchange therefor. Each Common Share that is owned by any direct or indirect wholly owned Subsidiary of Parent (other than Merger Sub) or the Company will be converted into such number of shares of the Surviving Corporation so as to maintain relative ownership percentages.

(c) Conversion of Common Shares. Each Common Share issued and outstanding immediately prior to the Effective Time (other than Common Shares to be cancelled or converted in accordance with Section 2.1(b) and any Dissenting Shares) will be converted into the right to receive an amount in cash equal to $229.00 (the “Merger Consideration”). From and after the Effective Time, all such Common Shares will no longer be outstanding and will automatically be cancelled and extinguished and will cease to exist, and each holder of a certificate share (a “Certificate”) or book-entry share (a “Book-Entry Share”) (as applicable) representing any such Common Shares will cease to have any rights with respect thereto, except the right to receive the Merger Consideration therefor, without interest thereon, upon the surrender of such Certificate or transfer of such Book-Entry Share (as applicable) in accordance with Section 2.2.

2.2 Exchange of Certificates.

(a) Paying Agent. Parent will designate Computershare Trust Company, N.A. or another bank or trust company that is reasonably acceptable to the Company to act as agent for the holders of the Common Shares in connection with the Merger (the “Paying Agent”) and to receive the funds to which holders of the Common Shares will become entitled in accordance with Section 2.1(c). The agreement pursuant to which Parent shall appoint the Paying Agent shall be in form and substance reasonably acceptable to Parent and the Company. Parent will deposit or cause to be deposited with the Paying Agent on a timely basis, promptly after the Effective Time (and no later than the same day as the Effective Time occurs to the extent that the Effective Time is before 1:00 p.m. (New York time), or else, the next Business Day) and as and when needed after the Effective Time, cash necessary to pay for the Common Shares converted in the Merger into the right to receive the Merger Consideration (the “Exchange Fund”). If the Exchange Fund is inadequate to pay the amounts to which holders of the Common Shares are entitled in accordance with Section 2.1(c), Parent will promptly deposit, or cause the Surviving Corporation promptly to deposit, additional cash with the Paying Agent sufficient to make all payments of Merger Consideration, and Parent and the Surviving Corporation will in any event be liable for payment thereof. The Paying Agent may invest the cash in the Exchange Fund as directed by Parent. Any interest and other income resulting from such investments will be paid to Parent.

(b) Exchange Procedures. Promptly after the Effective Time (but in no event later than five Business Days thereafter), the Paying Agent will mail to each holder of record of a Certificate, which immediately prior to the Effective Time represented outstanding Common Shares, whose shares were converted in accordance with Section 2.1(c) into the right to receive the Merger Consideration, (i) a letter of transmittal (which will specify that delivery will be effected, and risk of loss and title to the Certificate will pass, only upon delivery of the Certificate to the Paying Agent and will be in such form and have such other provisions as Parent may reasonably specify) and (ii) instructions for effecting the surrender of the Certificate in exchange for payment of the Merger

3

Consideration. Upon surrender of a Certificate for cancellation to the Paying Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly executed and properly completed and such other documents as may be reasonably requested by the Paying Agent, the holder of such Certificate will be entitled to receive in exchange therefor the Merger Consideration (such payments to be net of applicable Taxes withheld in accordance with Section 2.5) for each Common Share formerly represented by such Certificate, and the Certificate so surrendered will forthwith be cancelled. Until surrendered as contemplated by this Section 2.2, each Certificate will be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration in cash as contemplated by this Section 2.2, without interest thereon, and will not evidence any interest in, or any right to exercise the rights of a shareholder or other equity holder of, the Company or the Surviving Corporation. Notwithstanding anything to the contrary in this Agreement, any holder of Book-Entry Shares will not be required to deliver a Certificate or an executed letter of transmittal to the Paying Agent to receive the Merger Consideration that such holder is entitled to receive pursuant to this Section 2. In lieu thereof, each holder of record of one or more Book-Entry Shares whose Common Shares were converted into the Merger Consideration will upon receipt by the Paying Agent of such evidence, if any, as the Paying Agent may reasonably request, be entitled to receive, and Parent will cause the Paying Agent to pay, subject to any required withholding of Taxes, the Merger Consideration in respect of each such Common Share, and the Book-Entry Shares of such holder will forthwith be cancelled.

(c) Certain Transfer Taxes. If any payment in accordance with the Merger is to be made to a Person other than the Person in whose name the surrendered Certificate or Book-Entry Share is registered, it will be a condition of payment that (i) the Certificate or Book-Entry Shares surrendered will be properly endorsed or will be otherwise in proper form for transfer and (ii) the Person requesting such payment will have paid all transfer and other Taxes required by reason of the payment to a Person other than the registered holder of the Certificate or Book-Entry Share surrendered or will have established to the satisfaction of Parent that such Tax either has been paid or is not applicable. None of Parent, Merger Sub and the Surviving Corporation will have any liability for the transfer Taxes and other similar Taxes described in this Section 2.2(c) under any circumstances.

(d) Transfer Books; No Further Ownership Rights in Shares. At the Effective Time, the stock transfer books of the Company will be closed, and thereafter no further registration of transfers of Common Shares will be made on the records of the Company. From and after the Effective Time, the holders of Certificates or Book-Entry Shares evidencing ownership of Common Shares outstanding immediately prior to the Effective Time will cease to have any rights with respect to such Common Shares, except as otherwise provided for herein or by Law. If, after the Effective Time, Certificates or Book-Entry Shares are presented to the Surviving Corporation, then they will be cancelled and exchanged as provided in this Section 2.

(e) Termination of Exchange Fund; No Liability. At any time following 12 months after the Effective Time, the Surviving Corporation will be entitled to require the Paying Agent to deliver to it any funds (including any interest received with respect thereto) made available to the Paying Agent and not disbursed (or for which disbursement is pending subject only to the Paying Agent’s routine administrative procedures) to holders of Certificates and Book-Entry Shares, and thereafter such holders will be entitled to look only to the Surviving Corporation (subject to abandoned property, escheat or other similar Laws) only as general creditors thereof with respect to the Merger Consideration payable upon due surrender of their Certificates or Book-Entry Shares, without any interest thereon. Nonetheless, none of Parent, the Surviving Corporation nor the Paying Agent will be liable to any holder of a Certificate or Book-Entry Share for Merger Consideration delivered to a public official in accordance with any applicable abandoned property, escheat or similar Law. Any amounts remaining unclaimed by such holders at such time at which such amounts would otherwise escheat to or become property of any Governmental Authority will become, to the extent permitted by applicable Law, the property of the Surviving Corporation or its designee, free and clear of all claims or interest of any Person previously entitled thereto.

(f) Lost Certificates. If any Certificate will have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by

4

Parent or the Paying Agent, the posting by such Person of a bond in such amount as Parent or the Paying Agent may reasonably direct as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Certificate, the Paying Agent will deliver in exchange for such lost, stolen or destroyed Certificate the applicable Merger Consideration with respect thereto.

2.3 Dissenting Shares.

(a) Notwithstanding anything in this Agreement to the contrary, Common Shares outstanding immediately prior to the Effective Time and held by a holder who has complied with Section 262 of the DGCL with respect to such Common Shares (the “Dissenting Shares”) will not be converted into any right to receive the Merger Consideration unless such holder fails to perfect or withdraws or otherwise loses his, her or its right to appraisal. From and after the Effective Time, a shareholder who has properly exercised such appraisal rights will not have any rights of a shareholder of the Company or the Surviving Corporation with respect to the Dissenting Shares, except those provided in accordance with Section 262 of the DGCL. A holder of Dissenting Shares will be entitled to receive payment of the appraised value of the Dissenting Shares held by such holder in accordance with Section 262 of the DGCL, unless, after the Effective Time, such holder fails to perfect or withdraws or otherwise loses his, her or its right to appraisal, in which case the Dissenting Shares will be converted into and represent only the right to receive the Merger Consideration, without interest thereon, upon surrender of the Certificates or Book-Entry Shares, in accordance with Section 2.2.

(b) The Company will give Parent (i) prompt written notice of any written demands for appraisal under Section 262 of the DGCL (including copies of such demands), attempted withdrawals of such demands and any other communications received by the Company relating to rights of appraisal and (ii) the opportunity to participate in and direct all negotiations and Proceedings with respect to any demands for appraisal; provided that Parent shall not have the right to direct the Company to settle any negotiation or Proceeding with respect to any demands for appraisal with effect prior to the Effective Time. Except with the prior written consent of Parent, the Company will not voluntarily make any payment with respect to any demands for appraisal or settle or offer to settle any such demands for appraisal.

2.4 Company Incentive Plans.

(a) As of the Effective Time, each Company Option granted by the Company that is outstanding as of immediately prior to the Effective Time, whether or not then vested, will be cancelled and will immediately cease to be outstanding, without any payment with respect to such Company Option or cancellation thereof except as provided in the following sentence. In full satisfaction of the cancellation of each Company Option described in the immediately preceding sentence, Parent will cause the Surviving Corporation, as soon as reasonably practicable following the Effective Time (and no later than the second payroll date after the Effective Time), to pay, to the holder of such Company Option (which, for employees of the Company or any of the Company Subsidiaries, shall be in accordance with the general payroll practices of the Surviving Corporation), an amount in cash in respect thereof equal to the product of (i) the excess, if any, of the Merger Consideration over the per-share exercise price of such Company Option, multiplied by (ii) the number of Common Shares then subject to such Company Option (which number, in the case of Company Options subject to performance goals based on stock price hurdles, shall be determined based on actual performance in accordance with the terms of such Company Options, with any Company Options that do not vest being forfeited for no consideration) (such payment, if any, to be net of applicable Taxes withheld in accordance with Section 2.5 and without interest). For the avoidance of doubt, no consideration will be paid with respect to any Company Option that has a per-share exercise price that is greater than, or equal to, the Merger Consideration. As of the Effective Time, no Person will retain any rights with respect to any previously outstanding Company Options other than the rights of a holder to receive the payment contemplated by this Section 2.4(a).

(b) As of the Effective Time, each Company RSU, other than any Post-Signing Company RSU, that is outstanding as of immediately prior to the Effective Time, whether or not then vested, will be cancelled and will

5

immediately cease to be outstanding, without any payment with respect to such Company RSU or cancellation thereof except as provided in the following sentence. In full satisfaction of the cancellation of each Company RSU described in the immediately preceding sentence, Parent will cause the Surviving Corporation, as soon as reasonably practicable following the Effective Time (and no later than the second payroll date after the Effective Time), to pay to the holder of such Company RSU (which, for employees of the Company or any of the Company Subsidiaries, shall be in accordance with the general payroll practices of the Surviving Corporation), an amount in cash in respect thereof equal to the product of (i) the Merger Consideration, multiplied by (ii) the number of Common Shares then subject to such Company RSU (such payment, if any, to be net of applicable Taxes withheld in accordance with Section 2.5 and without interest). As of the Effective Time, no Person will retain any rights with respect to any Company RSUs (other than any Post-Signing Company RSUs) other than the rights of a holder to receive the payment contemplated by this Section 2.4(b).

(c) As of the Effective Time, each Company RSU granted after the date hereof that is unvested and outstanding as of immediately prior to the Effective Time (a “Post-Signing Company RSU”) will be substituted automatically with a Parent cash-based award (each, a “Parent Cash Award”) with respect to an amount in cash equal to the product of (i) the Merger Consideration, multiplied by (ii) the number of Common Shares then subject to such Post-Signing Company RSU. Each Parent Cash Award shall otherwise be subject to substantially the same terms and conditions applicable to such Post-Signing Company RSU as of immediately prior to the Effective Time.

(d) As of the Effective Time, each Company PSU, other than any Company Products PSU (each, a “Company Non-Products PSU”), that is outstanding as of immediately prior to the Effective Time, whether or not then vested, will be cancelled and will immediately cease to be outstanding, without any payment with respect to such Company Non-Products PSU or cancellation thereof except as provided in the following sentence. In full satisfaction of the cancellation of each Company Non-Products PSU described in the immediately preceding sentence, Parent will cause the Surviving Corporation, as soon as reasonably practicable following the Effective Time (and no later than the second payroll date after the Effective Time), to pay to the holder of such Company Non-Products PSU (which, for employees of the Company or any of the Company Subsidiaries, shall be in accordance with the general payroll practices of the Surviving Corporation), an amount in cash in respect thereof equal to the product of (i) the Merger Consideration, multiplied by (ii) the number of Common Shares then subject to such Company Non-Products PSU based on (A) for performance periods that are complete as of the Effective Time, actual performance as reasonably determined by the compensation committee of the Company Board of Directors in the ordinary course of business consistent with past practice and (B) for performance periods that are incomplete as of the Effective Time, the greater of the target and actual performance as of the fifth trading day prior to the Closing as reasonably determined by the compensation committee of the Company Board of Directors in the ordinary course of business consistent with past practice (provided that, for purposes of relative TSR metrics, such actual performance shall be calculated using the Merger Consideration as the Company stock value) (such payment, if any, to be net of applicable Taxes withheld in accordance with Section 2.5 and without interest). As of the Effective Time, no Person will retain any rights with respect to any Company Non-Products PSU other than the rights of a holder to receive the payment contemplated by this Section 2.4(d).

(e) As of the Effective Time, each Company PSU set forth on Section 2.4(e) of the Company Disclosure Letter (each, a “Company Products PSU”), that is unvested and outstanding as of immediately prior to the Effective Time, will be substituted automatically with a Parent Cash Award subject to the same performance-based vesting requirements (a “Parent Performance Cash Award”) with respect to that number of shares of Parent Common Stock that is equal to the product of (i) the Merger Consideration, multiplied by (ii) the number of Common Shares then subject to such Company Products PSU. Each Parent Performance Cash Award shall otherwise be subject to substantially the same terms and conditions applicable to such Company PSU as of immediately prior to the Effective Time.

6

(f) As of the Effective Time, the Company Stock Plans will terminate and all rights under any other plan, program or arrangement providing for the issuance or grant of any other interest with respect to the shares of the Company or any Company Subsidiary will be cancelled. The Company will take, or cause to be taken, all actions necessary to effectuate this Section 2.4, including sending any requisite notices, obtaining any necessary resolutions of the Company Board of Directors or a committee thereof, and obtaining all consents necessary to cash out and cancel, as described in Section 2.4(a), Section 2.4(b) and Section 2.4(d), all Company Options, Company RSUs (other than Post-Signing Company RSUs) and Company Non-Products PSUs so as to ensure that, after the Effective Time, no Person will have any rights under the Company Stock Plans with respect thereto other than rights to receive the payments contemplated by Section 2.4(a), Section 2.4(b) or Section 2.4(d). The Company will provide Parent with copies of all such notices, resolutions and other materials in connection with its obligations prior to Closing for Parent’s reasonable review and comment prior to distribution.

(g) As soon as practicable after the date hereof, the Company Board of Directors (or, if appropriate, the administrator of the Company ESPP) will pass such resolutions and take all actions with respect to the Company ESPP that are necessary to provide that (i) no new offering or new purchase period will commence following the date hereof unless and until this Agreement is terminated; (ii) from and after the date hereof, no new participants will be permitted to participate in the Company ESPP and participants will not be permitted to increase their payroll deductions or purchase elections from those in effect on the date of this Agreement; and (iii) each purchase right issued pursuant to the Company ESPP will be fully exercised not later than the earlier of (A) the last day of the current purchase period or (B) 10 Business Days prior to the Effective Time, and, immediately following such purchases, contingent upon the consummation of the Merger, the Company ESPP will terminate.

2.5 Withholding. Each of Parent, Merger Sub and the Surviving Corporation will be entitled to deduct and withhold, or cause the Paying Agent to deduct and withhold, from any amounts payable or otherwise deliverable in accordance with this Agreement or any ancillary agreement such amounts as are required to be deducted or withheld therefrom in accordance with the Internal Revenue Code of 1986 (the “Code”), or any other applicable federal, state, local or foreign Tax Law. To the extent such amounts are so deducted or withheld, such amounts will be treated for all purposes under this Agreement and any other agreement as having been paid to the Person to whom such amounts would otherwise have been paid. Notwithstanding anything to the contrary in this Agreement, any amounts subject to compensatory withholding and payable pursuant to or as contemplated by this Agreement will be remitted by the applicable payer to the Company for payment through the Company’s or a Company Subsidiary’s payroll procedures in accordance with applicable Law.

Except (a) as disclosed in the particular section or subsection of the Company Disclosure Letter referenced therein (it being understood and agreed that any information set forth in one section or subsection of the Company Disclosure Letter also will apply to each other section and subsection of this Agreement to which its applicability is reasonably apparent on its face from the text of the disclosure) or (b) other than with respect to Section 3.1, Section 3.2, Section 3.3, Section 3.4 (except to the extent a Company Material Contract was filed as an exhibit to any of the Company SEC Documents) and Section 3.5, as disclosed in the Company SEC Documents filed or furnished with the Securities and Exchange Commission (the “SEC”) by the Company since January 1, 2020 and at least one Business Day prior to the date of this Agreement (but, in each case, excluding any disclosure contained under the heading “Risk Factors” or in any “forward-looking statements” disclaimer or any other precautionary or other forward-looking statements) and to the extent publicly available on the SEC’s Electronic Data Gathering Analysis and Retrieval System (“EDGAR”), the Company hereby represents and warrants to Parent and Merger Sub as follows:

entity duly organized and validly existing and (ii) in good standing (where such concept is applicable) under the Laws of the jurisdiction of its incorporation, formation or organization, as applicable. Each of the Company and each Company Subsidiary has the requisite power and authority to conduct its business in the manner in which its business is currently being conducted and to own, lease and operate its properties and assets in the manner in which its properties and assets are currently owned, leased and operated, in each case, except as would not reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect. Each of the Company and each Company Subsidiary is duly qualified or licensed to do business in each jurisdiction in which the character or location of the property owned, leased or operated by it or the nature of the business conducted by it makes such qualification or licensing necessary, except where the failure to be so duly qualified or licensed has not had, individually or in the aggregate, a Company Material Adverse Effect. True and correct copies of the certificate of incorporation of the Company, as amended (the “Certificate of Incorporation”) and the bylaws of the Company, as amended (the “Bylaws”), in each case, as in effect as of the date of this Agreement, have been made available to Parent and are in full force and effect and the Company is not in violation of any of the provisions thereof. The organizational or governing documents of each of the Company Subsidiaries are in full force and effect, and none of the Company Subsidiaries is in material violation of any of the respective provisions thereof.

There are no other classes of capital stock of the Company and no bonds, debentures, notes or other Indebtedness or securities of the Company having the right to vote (or convertible into or exercisable for securities having the right to vote) on any matters on which holders of capital stock of the Company may vote authorized, issued or outstanding. As of the close of business on the Capitalization Date, there were (A) outstanding Company Options to purchase 5,682,590 Common Shares, (B) 3,025,659 outstanding Company RSUs, (C) 1,019,201 outstanding Company PSUs (assuming maximum performance), (D) rights to purchase a maximum of 543,628 Common Shares pursuant to the Company ESPP (determined based on the fair market value of a Common Share on the first day of the current offering period) and (E) 4,349,617 Common Shares reserved for future issuance under the Company Stock Plans.

No Company Option has been granted with a per share exercise price less than the fair market value of a Common Share on the applicable Company Option Grant Date, and the Company has not granted any Company Options that are subject to Section 409A of the Code.

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

5.2 No Solicitation.

(a) The Company will cease and terminate, and will direct its Representatives to cease and terminate, all solicitations, discussions, and negotiations with any Person with respect to any Company Acquisition Proposal as of the date of this Agreement. Except as provided in this Section 5.2, from the date of this Agreement until the earlier of termination of this Agreement or the Effective Time, the Company will not and will cause its Representatives not to directly or indirectly (A) initiate, solicit, knowingly encourage or knowingly facilitate the making of any inquiry, offer or proposal which constitutes or would reasonably be expected to lead to a Company Acquisition Proposal, (B) enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement, or similar agreement (an “Alternative Acquisition Agreement”) providing for the consummation of a transaction contemplated by any Company Acquisition Proposal or (C) engage in negotiations or discussions with, or provide any non-public information or data to, any Person (other than Parent or any of its Affiliates or Representatives) relating to any Company Acquisition

39

Proposal, or grant any waiver or release under any restriction from making a Company Acquisition Proposal, in each case, other than discussions solely to notify such Person of the terms of this Section 5.2 or to clarify the terms and conditions of such proposal or offer. The Company agrees that any violations of the restrictions set forth in this Section 5.2 by any of its Representatives will be deemed to be a breach of this Agreement (including this Section 5.2) by the Company.

(b) Notwithstanding anything to the contrary contained in this Agreement, at any time following the date of this Agreement and prior to the date on which the Company Requisite Vote is obtained, the Company and its Representatives may furnish non-public information concerning the Company’s business, properties or assets to any Person in accordance with a confidentiality agreement with terms not materially less favorable in the aggregate to the Company than those contained in the Confidentiality Agreement (it being understood that such agreement need not include a standstill provision) and may participate in discussions and negotiations with such Person concerning a Company Acquisition Proposal if, but only if, such Person has submitted a bona fide proposal to the Company relating to such Company Acquisition Proposal that did not result from a material breach of Section 5.2(a) and that the Company Board of Directors determines in good faith, after consultation with its financial advisors, either constitutes or could reasonably be expected to lead to a Superior Proposal. From and after the date of this Agreement and prior to the Shareholders Meeting, the Company will promptly (and in any event within 48 hours) notify Parent if the Company or any Company Subsidiary or Representative receives (i) any Company Acquisition Proposal or indication by any Person that it is considering making a Company Acquisition Proposal, (ii) any request for non-public information relating to the Company or any Company Subsidiary other than requests for information in the ordinary course of business and unrelated to a Company Acquisition Proposal or (iii) any inquiry or request for discussions or negotiations with respect to any Company Acquisition Proposal. The Company will provide Parent promptly (and in any event within such 48-hour period) with the identity of such Person and a correct and complete copy of such Company Acquisition Proposal, indication, inquiry or request (or, where such Company Acquisition Proposal is not in writing, a description of the material terms and conditions of such Company Acquisition Proposal, indication, inquiry or request), including any modifications thereto. The Company will keep Parent reasonably informed (orally and in writing) on a current basis (and in any event no later than 48 hours after the occurrence of any material changes, developments, discussions or negotiations) of the status of any Company Acquisition Proposal, indication, inquiry or request (including the material terms and conditions thereof and of any modification thereto). Without limiting the foregoing, the Company will promptly (and in any event within 48 hours) notify Parent orally and in writing if it determines to begin providing information or to engage in discussions or negotiations concerning a Company Acquisition Proposal and will in no event begin providing such information or engaging in such discussions or negotiations prior to providing such notice. The Company will not, and will cause each Company Subsidiary not to, enter into any agreement with any Person subsequent to the date of this Agreement that would restrict the Company’s ability to provide such information to Parent. The Company (A) will not, and will cause each Company Subsidiary not to, terminate, waive, amend or modify any provision of, or grant permission or request under, any standstill or confidentiality agreement to which it or any Company Subsidiary is or becomes a party, and (B) will, and will cause each Company Subsidiary to, use reasonable best efforts to enforce any such agreement, in each case, unless the Company Board of Directors determines in good faith, after consultation with the Company’s outside legal counsel, that the failure to do so would reasonably be likely to be inconsistent with the fiduciary duties of the Company Board of Directors to the Company’s shareholders under applicable Law, in which event the Company may take the actions described in these clauses (A) and (B) solely to the extent necessary to permit a third party to make a Company 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 Company Acquisition Proposal) in accordance with, and otherwise complying with, this Section 5.2. The Company will promptly provide to Parent any non-public information concerning the Company or any Company Subsidiary provided or made available in accordance with this Section 5.2(b) which was not previously provided or made available to Parent. For purposes of this Agreement, a “Superior Proposal” is a written Company Acquisition Proposal that did not result from a material breach of Section 5.2(a) (provided, that for this purpose the references to “20%” in the definition of “Company Acquisition Proposal” shall be deemed to be references to “50%”) on terms (x) which the Company Board of Directors determines in its good faith judgment

40

to be more favorable to the holders of the Common Shares than the transactions contemplated hereby (after consultation with its financial and legal advisors), taking into account all the terms and conditions of such Company Acquisition Proposal and this Agreement, including the likelihood that the transactions contemplated by such Company Acquisition Proposal or this Agreement will be completed.

(c) Except as set forth herein, neither the Company Board of Directors nor any committee thereof will (i) make any Company Adverse Recommendation Change or (ii) enter into any Alternative Acquisition Agreement providing for the consummation of a transaction contemplated by any Company Acquisition Proposal (other than a confidentiality agreement referenced in Section 5.2(b) entered into in the circumstances referenced in Section 5.2(b)). The Company, promptly following a determination by the Company Board of Directors that a Company Acquisition Proposal is a Superior Proposal, will notify Parent of such determination.

(d) Notwithstanding anything in Section 5.2(c) to the contrary, prior to the date on which the Company Requisite Vote is obtained, if the Company receives a Company Acquisition Proposal and the Company Board of Directors concludes in good faith, after consultation with outside counsel and its financial advisors, that such Company Acquisition Proposal constitutes a Superior Proposal after giving effect to all of the adjustments of this Agreement that are offered in writing by Parent, the Company Board of Directors may, if it determines in good faith, after consultation with outside counsel, that failure to take such action would reasonably be likely to be inconsistent with its fiduciary duties to the holders of the Common Shares in accordance with Law, (A) effect a Company Adverse Recommendation Change or (B) terminate this Agreement to enter into an Alternative Acquisition Agreement with respect to such Superior Proposal; provided, however, that the Company will not terminate this Agreement in accordance with clause (B) above, and any purported termination in accordance with clause (B) above will be void and of no force or effect, unless in advance of or concurrently with such termination the Company (1) pays the Termination Fee in accordance with Section 8.2 to the extent required thereby and (2) immediately following such termination enters into a binding definitive Alternative Acquisition Agreement for such Superior Proposal; provided, further, that the Company Board of Directors may not effect a Company Adverse Recommendation Change in accordance with clause (A) above or terminate this Agreement in accordance with clause (B) above unless (I) the Company has provided prior written notice to Parent, at least four Business Days in advance (the “Notice Period”), of its intention to take such action with respect to such Superior Proposal, which notice will specify the material terms and conditions of any such Superior Proposal (including the identity of the party making such Superior Proposal), and has contemporaneously provided a correct and complete copy of the proposed Alternative Acquisition Agreement with respect to such Superior Proposal, (II) prior to effecting such Company Adverse Recommendation Change or terminating this Agreement to enter into a definitive Alternative Acquisition Agreement with respect to such Superior Proposal, the Company has, and has caused its Representatives to, during the Notice Period, negotiate with Parent in good faith (to the extent Parent requests to negotiate) regarding any adjustments in the terms and conditions of this Agreement so that such Company Acquisition Proposal ceases to constitute a Superior Proposal and (III) following any negotiation described in clause (II) above, the Company Board of Directors concludes in good faith, after consultation with its outside counsel and financial advisors, that such Company Acquisition Proposal continues to constitute a Superior Proposal. In the event of any material revisions to the Superior Proposal after the start of the Notice Period, the Company is required to deliver a new written notice to Parent and to comply with the requirements of this Section 5.2(d) with respect to such new written notice, and the Notice Period will be deemed to have re-commenced on the date of such new notice, except that the references to four Business Days will be deemed two Business Days. Any Company Adverse Recommendation Change will not change the approval of the Company Board of Directors for purposes of causing any state takeover statute or other Law to be inapplicable to the transactions contemplated hereby.

(e) The Company Board of Directors may make a Company Adverse Recommendation Change in response to a Company Intervening Event if the Company Board of Directors has concluded in good faith, after consultation with its outside counsel, that failure to make a Company Adverse Recommendation Change on account of the Company Intervening Event would reasonably be likely to be inconsistent with its fiduciary duties; provided, however, that the Company Board of Directors will not make a Company Adverse

41

Recommendation Change unless the Company has (i) provided to Parent at least four Business Days’ prior written notice advising Parent that the Company Board of Directors intends to take such action and specifying the Company Intervening Event in reasonable detail and (ii) during such four-Business Day period, if requested by Parent, engaged in good faith negotiations with Parent to amend this Agreement in such a manner that obviates the need or reason for the Company Adverse Recommendation Change.

(f) The Company will promptly (but in no event later than three Business Days after the date of this Agreement) request that each Person that has executed a confidentiality agreement in connection with a potential Company Acquisition Proposal that remains in effect return (or destroy, to the extent permitted by the applicable confidentiality agreement) all confidential information furnished to such individual or entity by or on behalf of the Company or any Company Subsidiary.

(g) Nothing in this Section 5.2 or elsewhere in this Agreement will prohibit the Company from (i) taking and disclosing to the shareholders 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 shareholders of the Company that is required by applicable Law; provided, that this Section 5.2(g) will not be deemed to permit the Company Board of Directors to make a Company Adverse Recommendation Change except to the extent permitted by Section 5.2(d).

5.3 Proxy Statement. The Company will, as soon as reasonably practicable following the date of this Agreement, and in any event within 25 Business Days, prepare and file with the SEC the Proxy Statement in preliminary form, and the Company will use its reasonable best efforts to respond as promptly as reasonably practicable to any comments of the SEC with respect thereto. The Company will notify Parent promptly (and in any case no later than 24 hours) of the receipt of any comments from the SEC or its staff and of any request by the SEC or its staff for amendments or supplements to the Proxy Statement or for additional information and will supply Parent with copies of all correspondence between the Company or any of its Representatives, on the one hand, and the SEC or its staff, on the other hand, with respect to the Proxy Statement. If at any time prior to receipt of the Company Requisite Vote there will occur any event that should be set forth in an amendment or supplement to the Proxy Statement, including correcting any information that has become false or misleading in any material respect, the Company will promptly prepare and mail to its shareholders such an amendment or supplement. Parent and its counsel will be given a reasonable opportunity to review the Proxy Statement before it is filed with the SEC and the Company will give due consideration to all reasonable additions, deletions, or changes thereto suggested by Parent and its counsel. The Company will (a) establish a record date, (b) commence a broker search pursuant to Section 14a-13 of the Exchange Act in connection therewith and (c) thereafter commence mailing the Proxy Statement to the Company’s shareholders as promptly as practicable after (i) the first Business Day after the date that is 10 calendar days after filing the Proxy Statement in preliminary form if, prior to such date, the SEC does not provide comments or indicates that it does not plan to provide comments or (ii) the date on which the Company shall have been informed by the SEC staff that it has no further comments on the document. Subject to the terms and conditions of this Agreement, the Proxy Statement will include the Company Board Recommendation.

5.4 Shareholders Meeting. The Company will, as soon as reasonably practicable following the mailing of the Proxy Statement, duly call, give notice of, convene and hold a meeting of its shareholders (the “Shareholders Meeting”) for the purpose of seeking the Company Requisite Vote and, subject to Section 5.2, use its reasonable best efforts to solicit approval of this Agreement. The Company will schedule the Shareholders Meeting to be held within 25 Business Days of the initial mailing of the Proxy Statement (or if the Company’s nationally recognized proxy solicitor advises that 25 Business Days from the date of mailing the Proxy Statement is insufficient time to submit and obtain the Company Requisite Vote, such later date to which Parent consents (such consent not to be unreasonably delayed, conditioned or withheld)); provided, that, the Company shall be permitted to postpone or adjourn the Shareholders Meeting, but only (a) if the Company is unable to obtain a quorum of its shareholders at such time, to the extent necessary in order to obtain a quorum of its shareholders,

42

(b) if there are not sufficient affirmative votes in Person or represented by proxy at such meeting to obtain the Company Requisite Vote, to allow reasonable time for solicitation of proxies for purposes of obtaining the Company Requisite Vote, (c) if the Company Board of Directors has determined in good faith, after consultation with Parent, that such delay is required by applicable Law to comply with comments made by the SEC with respect to the Proxy Statement or to allow reasonable time for the mailing of any supplemental or amended disclosure required thereby or (d) if the Company is required to do so by a court of competent jurisdiction; provided, further, that: (i) to the extent permitted by applicable Law, the Company may not postpone or adjourn the Shareholders Meeting by more than 15 calendar days past the originally scheduled date without Parent’s prior consent (such consent not to be unreasonably delayed, conditioned or withheld), (ii) if applicable, the Company shall respond as promptly as reasonably practicable to resolve any SEC comments and (iii) the Company shall reconvene the Shareholders Meeting at the earliest practicable date on which the Company Board of Directors reasonably expects to have sufficient affirmative votes to adopt this Agreement.

Parent will use reasonable best efforts to cause the Surviving Corporation to file with the SEC (a) a Form 25 on the Closing Date and (b) a Form 15 on the first Business Day that is at least 10 days after the date the Form 25 is filed (such period between the Form 25 filing date and the Form 15 filing date, the “Delisting Period”). If the Surviving Corporation is reasonably likely to be required to file any reports in accordance with the Exchange Act during the Delisting Period, the Company will deliver to Parent at least five Business Days prior to the Closing a substantially final draft of any such reports reasonably likely to be required to be filed during the Delisting Period (“Post-Closing SEC Reports”). The Post-Closing SEC Reports provided by the Company in accordance with this Section 6.1 will (i) 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 made therein, in the light of the circumstances under which they were made, not misleading and (ii) comply in all material respects with the provisions of applicable Laws.

6.2 Access to Information. Subject to applicable Law, including Antitrust Law, and to reasonable restrictions relating to COVID-19, during the period from the date of this Agreement until the earlier of the Effective Time and the termination of this Agreement, Parent will be entitled, through its employees and Representatives, to have reasonable access to the assets, properties, business, operations, personnel and

43

Representatives of the Company and each Company Subsidiary solely for the purpose of furthering the transactions contemplated by this Agreement and for integration planning purposes. Any such investigation and examination will be conducted during normal business hours upon reasonable advance notice, at Parent’s expense and under the supervision of appropriate personnel of the Company and in such a manner as not to unreasonably interfere with the normal operation of the business of the Company, and will be subject to the Company’s reasonable security measures and insurance requirements, except as may otherwise be required or restricted by Law, so as to limit disruption to or impairment of the Company’s business, and the Company will cooperate fully therein. No investigation by Parent will diminish or obviate any of the representations, warranties, covenants or agreements of the Company contained in this Agreement. The Company will furnish the Representatives of Parent during such period with all such information and copies of such documents concerning the affairs of the Company as such Representatives may reasonably request and cause its Representatives to cooperate fully with such Representatives of Parent, in each case, in connection with such purposes. Nothing herein will require the Company to disclose any information to Parent if such disclosure would, in its reasonable discretion and after notice to Parent, (i) jeopardize any attorney-client or other legal privilege (so long as the Company has reasonably cooperated with Parent to disclose such information on a basis that does not waive such privilege with respect thereto), (ii) contravene any applicable Law or protective order (so long as the Company has used reasonable best efforts to provide such information in a way that does not contravene applicable Law or such protective order) or (iii) result in the disclosure of any Trade Secrets of third parties; provided, that information will be disclosed subject to execution of a joint defense agreement in customary form, and disclosure may be limited to external counsel for Parent, to the extent the Company determines doing so may be reasonably required for the purpose of complying with applicable Antitrust Laws. With respect to the information disclosed pursuant to this Section 6.2, Parent will comply with, and will instruct Parent’s Representatives to comply with, all of its obligations under the Confidentiality Agreement. From the date of this Agreement until the earlier of termination of this Agreement or the Effective Time, the Company shall provide Parent the information described in Section 6.2 of the Company Disclosure Letter. Notwithstanding anything to the contrary herein, no breach by the Company of its obligations under the foregoing sentence shall constitute a breach of this Agreement by the Company for purposes of Section 7.2(b) or Section 8.1(c)(i).

6.3 Public Disclosure. The initial press release concerning the Merger will be a joint press release and, thereafter, so long as this Agreement is in effect, neither Parent, Merger Sub nor the Company will disseminate any press release or other public announcement concerning the Merger or this Agreement or the other transactions contemplated by this Agreement, except as may be required by Law or by any listing agreement with a national stock exchange, without the prior consent of each of the other parties hereto, which consent will not be unreasonably withheld, conditioned or delayed. Without prior consent of the other parties hereto, each party hereto may disseminate information substantially similar to information included in a press release or other communication previously approved for public distribution by the other parties hereto. The restrictions of this Section 6.3 will not apply to communications by Parent, Merger Sub or the Company regarding a Company Acquisition Proposal or a Company Adverse Recommendation Change or following a Company Adverse Recommendation Change.

6.4 Regulatory Filings; Efforts to Consummate.

(a) Reasonable Best Efforts. Upon the terms and subject to the conditions set forth in this Agreement and provided that at all times the provisions of Section 6.4(b)-(f) shall govern the matters set forth therein, including efforts required to obtain any Regulatory Approval, the Company and Parent shall cooperate with each other and use (and shall cause their respective Subsidiaries to use) their respective reasonable best efforts to obtain all consents, registrations, approvals, permits, and authorizations, in each case, necessary or advisable in order to consummate the transactions contemplated by this Agreement as promptly as reasonably practicable and in any event prior to the Outside Date.

(b) Regulatory Approvals. Subject to the terms of this Section 6.4(b) and Section 6.4(d), the Company and Parent shall cooperate with each other and use (and shall cause their respective Subsidiaries to use) their

44

respective reasonable best efforts to (x) file with the FTC and the Antitrust Division of the DOJ a Notification and Report Form relating to this Agreement and the Merger as required by the HSR Act promptly following the date of this Agreement; and (y) file comparable pre-merger or post-merger notification filings, forms and submissions with any Governmental Authority that are required by other applicable Antitrust Laws or Foreign Investment Laws or that are, in the reasonable judgment of Parent, advisable in connection with the Merger. Each of the Company and Parent, as applicable, shall (and shall cause their respective Subsidiaries to):

(i) cooperate and coordinate with the other in the making of the filings referenced in this Section 6.4(b);

(ii) use its respective reasonable best efforts to supply the other with any information that may be required in order to make such filings;

(iii) use its respective reasonable best efforts to supply any additional information that reasonably may be required or requested by the FTC, the DOJ or the Governmental Authorities of any other applicable jurisdiction in which any such filing is made;

(iv) use its respective reasonable best efforts to take all action necessary to (1) cause the expiration or termination of the applicable waiting periods pursuant to the HSR Act and any other Antitrust Laws or Foreign Investment Laws applicable to the Merger; and (2) obtain any required consents pursuant to any Antitrust Laws or Foreign Investment Laws applicable to the Merger, in each case as soon as practicable, and in any event prior to the Outside Date;

(v) contest, defend and appeal any legal Proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the Merger; and

(vi) prior to independently participating in any meeting, or engaging in any substantive conversation, with any Governmental Authority in respect of any such filings or any investigations or other inquiries relating thereto, to the extent reasonably practicable, provide notice to the other party of such meeting or conversation and, unless prohibited by such Governmental Authority, the opportunity to attend or participate.

Parent shall, after good faith consultation with the Company and after considering, in good faith, the Company’s views and comments, control and lead all communications, negotiations, timing decisions, and strategy on behalf of the parties relating to any approval under the Antitrust Laws or Foreign Investment Laws and any litigation matters pertaining to the Antitrust Laws or Foreign Investment Laws applicable to the Merger, and the Company shall take all reasonable actions to support Parent in connection therewith. Each of the Company and Parent will permit the other party and its Representatives to review in advance any written communication proposed to be made by such party to any Governmental Authority regarding the Merger and will consider in good faith the views of the other party and promptly inform the other party of any substantive communication from any Governmental Authority regarding the Merger in connection with such filings. If any party or Affiliate thereof receives a request for additional information or documentary material from any Governmental Authority with respect to the Merger pursuant to the HSR Act or any other Antitrust Laws or Foreign Investment Laws applicable to the Merger, then such party will use reasonable best efforts to make (or cause to be made), as soon as reasonably practicable and after consultation with the other parties, an appropriate response in compliance with such request. Parent shall not (i) withdraw, or offer or commit to withdraw, any filing or notification described in Section 6.4(b)(x) or (y) or (ii) commit to or agree with any Governmental Authority to stay, toll or extend any applicable waiting period under the HSR Act or not consummate the transactions contemplated by the Agreement, in each case, without the prior written consent of the Company (not to be unreasonably withheld, conditioned or delayed). Each party will bear its own costs of preparing its own pre-merger notifications and similar filings and notices in other jurisdictions and related expenses incurred to make or obtain any approval, clearance or notice under any applicable Antitrust Law (including under the HSR Act), Foreign Investment Law or other applicable Law. Parent will be responsible for payment of the applicable filing fees associated with any such Antitrust Laws or Foreign Investment Laws.

45

(c) Notwithstanding any other requirement in this Section 6.4, where a party (a “Disclosing Party”) is required under this Section 6.4 to provide information to another party (a “Receiving Party” ) that the Disclosing Party deems to be competitively sensitive information, the Disclosing Party may comply with such requirement by restricting the provision of such competitively sensitive only to antitrust counsel of the Receiving Party and providing to the Receiving Party, upon request of the Receiving Party, a redacted version of such information which does not contain any such competitively sensitive information.

(d) Regulatory Remedies. Notwithstanding anything in this Agreement to the contrary, reasonable best efforts will not obligate Parent or any Subsidiary of Parent to: (i) make any commitment to or undertake or enter into agreements or agree to the entry of an order or decree with any Governmental Authority, (ii) commit to sell or dispose of, or hold separate or agree to sell or otherwise dispose of, assets, categories of assets or business of the Parent, the Company, the Surviving Corporation or any other Subsidiary of Parent or the Company, (iii) without limiting the express obligations of Parent or any Subsidiary of Parent set forth in Section 6.4(b)(i), 6.4(b)(ii), 6.4(b)(iii), 6.4(b)(v) or 6.4(b)(vi), commit to or accept any operational restriction or take or commit to take any action related to the Parent, the Company, the Surviving Corporation or any other Subsidiary of Parent or the Company, (iv) commit to terminate, amend or replace any existing relationships and contractual rights and obligations of the Parent, the Company, the Surviving Corporation or any other Subsidiary of Parent or the Company, (v) terminate any relevant venture or other arrangement of the Parent, the Company, the Surviving Corporation or any other Subsidiary of Parent or the Company or (vi) effectuate any other change or restructuring of the Parent, the Company, the Surviving Corporation or any other Subsidiary of Parent or the Company. The Company shall not, and shall cause its Subsidiaries not to, take any of the foregoing actions in clauses (i) through (vi) with respect to the Company or any Subsidiary of the Company unless consented to in writing by Parent, provided that the Company shall, and shall cause each Subsidiary of the Company to, undertake such actions if requested by Parent if the effectiveness of such action is conditioned upon the occurrence of the Closing.

(e) Between the date of this Agreement and the Closing, neither Parent nor the Company shall engage in, or permit any of its Subsidiaries to engage in, any merger or acquisition, including any business combinations, asset acquisitions or sales, consolidations, mergers, stock acquisitions or sales, joint ventures, collaborations, licensing or other strategic transactions, that would, individually or in the aggregate, reasonably be expected to prevent, delay or impair the consummation of the Merger by the Outside Date.

(f) If, prior to the Effective Time (i) the U.K. Competition and Markets Authority (the “CMA”) indicates in writing to Parent that it has decided to formally investigate the Merger and, accordingly, requests Parent to submit a merger notice in the form prescribed under the Enterprise Act 2002, (ii) the European Commission (the “EC”) indicates in writing to Parent that a member state of the European Union or the EC is making, or has made, a referral of the Merger to the EC under Article 22 of the EU Merger Regulation, or (iii) a merger control, foreign direct investment or national security inquiry or review is initiated or commenced by a Governmental Authority listed on Section 6.4(f) of the Company Disclosure Letter, then, Parent shall provide to the Company a copy of such written indication or filing, form or other submission as promptly as practicable after its receipt or submission thereof, as applicable, and if such indication or filing, form or other submission shall have been so provided, approval of the Merger by the CMA under the Enterprise Act of 2002 or the EC under Article 22 of the EU Merger Regulation or such other Governmental Authority under the applicable Law in its jurisdiction, as the case may be, shall thereupon be deemed to be added to Section 7.1(a)(i) of the Company Disclosure Letter and shall be a Regulatory Approval.

6.5 Notification of Certain Matters; Litigation. The Company will promptly after it has notice of any of the following, to the extent permitted by Law, notify Parent of (i) any written notice or other written communication from any Person alleging that the consent of such Person is or may be required in connection with the transactions contemplated hereby, or (ii) any notice or other communication from any Governmental Authority in connection with the transactions contemplated hereby. The Company will promptly notify Parent of any Proceedings instituted or threatened against the Company or any of its directors, officers or Affiliates, by any holders of the Shares of the Company, before any court or Governmental Authority, relating to this Agreement or

46

the transactions contemplated hereby, or seeking damages or discovery in connection with such transactions (“Transaction Litigation”). The Company will consult with Parent with respect to the defense or settlement of any Transaction Litigation, will consider Parent’s views with respect to such Transaction Litigation, and will not settle or materially stipulate with respect to any such Transaction Litigation without Parent’s written consent (not to be unreasonably withheld, conditioned or delayed).

6.6 Indemnification.

(a) From and after the Effective Time, Parent agrees that it will cause the Surviving Corporation to indemnify, defend and hold harmless, to the fullest extent permitted under applicable Law, each current or former director and officer of the Company (determined as of the Effective Time), in each case, when acting in such capacity or in serving as a director, officer, member, trustee or fiduciary of another entity or enterprise, including a Benefit Plan, at the request or benefit of the Company (collectively, the “Indemnified Parties”) against any costs or expenses (including attorneys’ fees and expenses), amounts paid in settlement, judgments, fines, losses, claims, damages or liabilities incurred in connection with, arising out of or otherwise related to any actual or alleged Proceeding, in connection with, arising out of or otherwise related to matters existing or occurring or alleged to have occurred prior to or at the Effective Time, whether asserted or claimed prior to, at or after the Effective Time, including actions to enforce this provision or any other indemnification or advancement right of any Indemnified Party, and Parent or the Surviving Corporation shall also advance reasonable expenses as incurred to the fullest extent permitted under applicable Law (subject to the execution of an undertaking by or on behalf of the Indemnified Party to repay such amount if it shall ultimately be determined, by final judicial decision from which there is no further right to appeal, that the Indemnified Party is not entitled to be indemnified under this Section 6.6). In the event of any such actual or alleged Proceeding, Parent and the Surviving Corporation shall cooperate with the Indemnified Party in the defense of any such actual or alleged Proceeding. For a period of six years from the Effective Time, the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, maintain in effect the exculpation, indemnification and advancement of expenses equivalent to the provisions of the Company’s certificate of incorporation and bylaws as in effect immediately prior to the Effective Time with respect to acts or omissions occurring prior to the Effective Time and shall not amend, repeal or otherwise modify any such provisions in any manner that would adversely affect the rights thereunder of any Indemnified Parties, except to the extent required by applicable Law; provided that all rights to indemnification in respect of any claim made for indemnification within such period shall continue until the disposition of such action or resolution of such claim. From and after the Effective Time, Parent shall guarantee and stand surety for, and shall cause the Surviving Corporation to honor, all indemnification Contracts described in Section 6.6(a) of the Company Disclosure Letter and Parent shall not, and shall cause its Subsidiaries (including the Surviving Corporation) not to, amend, repeal or otherwise modify any such Contracts in any manner that would adversely affect the rights thereunder of any Indemnified Parties.

(b) Prior to the Effective Time, the Company shall or, if the Company is unable to, Parent shall cause the Surviving Corporation, as of the Effective Time, to purchase from the Company’s directors’ and officers’ liability insurance carrier as of the date of this Agreement or one or more insurance carriers with the same or better credit rating as such carrier, a six-year prepaid “tail” policy, with terms, conditions, retentions and limits of liability that are no less favorable to the insureds than the coverage provided under the Company’s existing policies of directors’ and officers’ liability insurance and fiduciary liability insurance (the “Existing Policies”), with respect to matters arising on or before the Effective Time (including in connection with this Agreement and the transactions or actions contemplated by this Agreement), and Parent shall cause such policy to be maintained in full force and effect, for its full term, and cause all obligations thereunder to be honored by the Surviving Corporation; provided that the Company shall not pay, and the Surviving Corporation shall not be required to pay, in excess of the amount set forth in Section 6.6(b) of the Company Disclosure Letter. If the Company or the Surviving Corporation for any reason fail to obtain such “tail” insurance policies prior to or as of the Effective Time, Parent shall, for a period of six years from the Effective Time, cause the Surviving Corporation to maintain in effect the current policies of directors’ and officers’ liability insurance and fiduciary liability insurance maintained by the Company as of the date of this Agreement with the Company’s directors’ and

47

officers’ liability insurance carrier as of the date of this Agreement or one or more insurance carriers with the same or better credit rating as such carrier with respect to matters arising on or before the Effective Time; provided that after the Effective Time, Parent shall not be required to pay annual premiums in excess of the amount set forth in Section 6.6(b) of the Company Disclosure Letter, but in such case shall purchase as much coverage as practicable for such amount.

(c) The covenants contained in this Section 6.6 are intended to be for the benefit of, and shall be enforceable by, each of the Indemnified Parties and their respective heirs and shall not be deemed exclusive of any other rights to which any such Person is entitled, whether pursuant to Law, contract or otherwise. Nothing in this Agreement is intended to, shall be construed to or shall release, waive or impair any rights to directors’ and officers’ insurance claims under any policy that is or has been in existence with respect to the Company or any Company Subsidiaries for any of their respective directors, officers or other employees.

(d) In the event that Parent or the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or substantially all of its properties and assets to any Person, then, and in each such case, proper provision shall be made so that the successors or assigns of Parent or the Surviving Corporation, as the case may be, shall assume the obligations of Parent or the Surviving Corporation, as the case may be, set forth in this Section 6.6, unless such result occurs by operation of Law.

6.7 Employee Benefits.

(a) Until the first anniversary of the Effective Time (or an earlier termination of the relevant employee’s employment), each employee of the Company or any of the Company Subsidiaries who continues to be employed by the Surviving Corporation or any of its Subsidiaries following the Effective Time (a “Continuing Employee”) will be provided (i) an annual base salary or wage rate and annual target cash bonus opportunity that are, in each case, no less favorable than the annual base salary or wage rate and annual target cash bonus opportunity provided to such Continuing Employee as of immediately prior to the Effective Time, and (ii) employee benefits that are substantially comparable in the aggregate to the employee benefits (excluding equity compensation, change in control, transaction or retention payments, defined benefit, nonqualified deferred compensation, severance benefits, post-retirement or retiree medical benefits) that are in effect immediately prior to the date of this Agreement. Each Continuing Employee will be provided severance benefits as set forth on Section 6.7(a) of the Company Disclosure Letter.

(b) As of the Effective Time, all Continuing Employees in the United States (and in any other jurisdiction where permitted by Law) will become subject to Parent’s vaccine mandate, which requires colleagues to be fully vaccinated and to provide proof of full vaccination or to be granted a medical or religious accommodation by Parent.

(c) With respect to each applicable benefit plan of Parent or its Affiliates, each Continuing Employee who participates in any such plan will receive service credit for all periods of employment with the Company or any of the Company Subsidiaries, as applicable, prior to the Effective Time for purposes of vesting, benefit accrual and eligibility, in each case, in accordance with the terms of such plans, to the same extent and for the same purposes thereunder as such service was recognized under an analogous Benefit Plan in effect on the date of this Agreement; provided, that the foregoing will not apply (i) to the extent that its application would result in a duplication of benefits with respect to the same period of service or (ii) for purposes of (x) any “retirement savings contribution” under any Parent employee plan providing 401(k) plan benefits, (y) any retiree medical plan or defined benefit plan or (z) any benefit plan, program or policy of Parent or the Surviving Corporation that is a frozen plan or that provides benefits to a grandfathered employee population, either with respect to level of benefits or participation; provided, further, that the Company has made available to Parent such information as is reasonably requested by Parent to satisfy its obligations under this Section 6.7(c). If, on or after the Effective

48

Time, any Continuing Employee becomes covered by any benefit plan providing medical, dental, health, pharmaceutical or vision benefits (a “Successor Plan”), other than the plan in which he or she participated immediately prior to the Effective Time (a “Prior Plan”), Parent will (1) cause any restrictions or limitations with respect to pre-existing condition exclusions and actively-at-work requirements to be waived for such Continuing Employee and his or her eligible dependents (except to the extent such exclusions or requirements were applicable under the corresponding Prior Plan), and (2) use commercially reasonable efforts to permit such Continuing Employee to take into account any eligible expenses incurred by such employee and his or her covered dependents during the plan year in which the employee elects to be covered by the Successor Plan for purposes of satisfying all deductible, coinsurance and maximum out-of-pocket requirements applicable to such employee and/or his or her covered dependents for that year, to the extent that such expenses were incurred during the applicable period in which such employee or covered dependent was covered by a corresponding Prior Plan.

(d) If, no later than seven days prior to the Effective Time, Parent provides written notice to the Company that the Company 401(k) Plan (the “401(k) Plan”) shall be terminated, the appropriate committee shall take actions necessary to terminate the 401(k) Plan, such termination to be effective as of the day prior to the Closing Date and contingent upon the occurrence of the Effective Time. Parent shall, as soon as reasonably practicable after the Effective Time (and consistent with Parent’s administrative practices with respect to similarly situated employees in similar acquisitions), offer participation in Parent’s Tax qualified defined contribution plan (the “Parent 401(k) Plan”) to each Continuing Employee who was an active participant in the Company 401(k) Plan as of the date of its termination and who satisfies the eligibility requirements of the Parent 401(k) Plan. If the 401(k) Plan is terminated in accordance with this Section 6.7(d), then (i) Parent shall provide each Continuing Employee with an opportunity to make catch-up contributions with respect to the period between the Closing Date and the date on which Continuing Employees are offered to commence participation in the Parent 401(k) Plan, subject to any limitations under the Code; and (ii) if elected by such Continuing Employee in accordance with applicable Law, Parent shall permit the Parent 401(k) Plan to, following the Closing Date, accept a “direct rollover” to such Parent 401(k) Plan of the account balances (including any participant loans) of such Continuing Employee.

(e) The provisions contained in this Section 6.7 are included for the sole benefit of the parties hereto, and nothing in this Section 6.7, whether express or implied, will create any third-party beneficiary or other rights in any other person, including, without limitation, any current or former employee, director, officer, other service provider, any participant in any Benefit Plan or other benefit plan or arrangement, or any dependent or beneficiary thereof, or any right to continued employment or service, or any term or condition of employment with the Company, any Company Subsidiary, Parent, the Surviving Corporation or any of their respective Affiliates. Nothing contained herein, whether express or implied, will be treated as the establishment of, amendment to, waiver or other modification of any Benefit Plan or other employee benefit plan, program, policy, agreement, or arrangement, or will limit the right of the Company, any Company Subsidiary, Parent, the Surviving Corporation or any of their respective Affiliates to amend, terminate or otherwise modify any Benefit Plan or other employee benefit plan, program, policy, agreement, or arrangement in accordance with its terms.

6.8 Takeover Laws. If any “fair price,” “business combination” or “control share acquisition” statute or other similar statute or regulation is or may become applicable to any of the transactions contemplated hereby, the parties hereto will use their respective commercially reasonable efforts to (a) take such actions as are reasonably necessary so that the transactions contemplated hereunder may be consummated as promptly as practicable on the terms contemplated hereby and (b) otherwise take all such actions as are reasonably necessary to eliminate or minimize the effects of any such statute or regulation on such transactions.

6.9 Further Assurances. Other than with respect to antitrust matters which will be governed by Section 6.4, on the terms and subject to the conditions set forth in this Agreement, each of Parent, Merger Sub and the Company will use its reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable to

49

consummate and make effective, in the most expeditious manner practicable, the Merger and the other transactions contemplated hereby, in accordance with the terms of this Agreement. In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement, the proper officers and directors of the Surviving Corporation and Parent will use all reasonable efforts to take, or cause to be taken, all such necessary actions. Parent will cause Merger Sub to fulfill all of Merger Sub’s obligations in accordance with this Agreement.

If this Agreement is terminated in accordance with Section 8.1, this Agreement will become null and void and be of no further force or effect and there will be no liability on the part of Parent, Merger Sub or the Company (or any of their respective directors, officers, employees, shareholders, agents or Representatives), except as set forth in the last sentence of Section 6.2, Section 8 and Section 9, each of which will remain in full force and effect and survive any termination of this Agreement; provided, however, that nothing herein will relieve any party from liability for actual and intentional fraud in the making of any of its representations and warranties set forth in this Agreement or Willful Breach of any of its covenants or agreements set forth in this Agreement.

(b) If Parent terminates this Agreement in accordance with Section 8.1(c)(ii), the Company will promptly pay Parent a fee (the “Termination Fee”) of $1,646,000,000 in cash, but in no event later than two Business Days after the date of receipt of Parent’s termination notice. If the Company terminates this Agreement in accordance with Section 8.1(d)(ii), it will, in connection with and as a condition to such termination, pay Parent the Termination Fee. If (i) Parent or the Company, as applicable, terminates this Agreement in accordance with Section 8.1(b)(ii), Section 8.1(b)(iii) or Section 8.1(c)(i) and, at the time of such termination, the Company Requisite Vote shall not have been obtained, (ii) prior to such time, a Company Acquisition Proposal has been publicly announced and not publicly withdrawn at least four Business Days prior to the Shareholders Meeting, and (iii) within 12 months after the date on which this Agreement is terminated, the Company enters into a definitive agreement with respect to a Company Acquisition Proposal that is ultimately consummated or a Company Acquisition Proposal is consummated (provided that, for purposes of this clause (iii), the references to “20%” in the definition of “Company Acquisition Proposal” shall be deemed to be references to “50%”), then the Company will pay Parent the Termination Fee upon the consummation of the transaction contemplated by such Company Acquisition Proposal.

If the Company fails to promptly make any payment required in accordance with this Section 8.2(b), the Company will indemnify Parent for its fees and expenses (including attorneys’ fees and expenses) incurred in connection with pursuing such payment and will pay interest on the amount of the payment at the prime rate of Bank of America (or its successors or assigns) in effect on the date the payment was payable in accordance with this Section 8.2(b). The Company will not be required to pay the Termination Fee pursuant to this Section 8.2(b) more than once. Except in the case of the Company’s actual and intentional fraud in the making of any of its representations and warranties set forth in this Agreement or Willful Breach by the Company of its covenants or agreements set forth in this Agreement, in the event that the Termination Fee is triggered and is paid pursuant to this Section 8.2(b), receipt of the Termination Fee shall be the sole and exclusive remedy of Parent and its Affiliates and Representatives against the Company and its Affiliates and Representatives under this Agreement or arising out of or related to this Agreement or the transactions contemplated hereby, and upon payment of such amount, neither the Company nor any of its Affiliates or Representatives shall have any further liability or obligation relating to or arising out of this Agreement or the transactions contemplated hereby, in each case whether based on contract, tort or strict liability, by the enforcement of any assessment, by any legal or equitable Proceeding, by virtue of any applicable Law or otherwise.

53

regulation, Order or injunction that has caused Section 7.1(c) to not be satisfied is in respect of, pursuant to or arises under any Antitrust Law or Foreign Investment Law), (C) all of the conditions set forth in Section 7.2 are satisfied (or, in the case of conditions that by their terms are to be satisfied at the Closing, are capable of being satisfied on such date), and (D) a breach by the Company of its obligations in Section 6.4 has not contributed materially and substantially to the applicable Restraint that gives rise to the termination right pursuant to Section 8.1(b)(i) or the failure of any of the conditions set forth in Section 7.1(a) or Section 7.1(c) to be satisfied, then Parent will promptly pay or cause to be paid to the Company a fee (the “Reverse Termination Fee”) of $2,224,000,000 in cash, but in no event later than two Business Days after such termination. All amounts due hereunder will be payable by wire transfer in immediately available funds to such account as the Company may designate in writing to Parent. If Parent fails to promptly make any payment required in accordance with this Section 8.2(c), Parent will indemnify the Company for its fees and expenses (including attorneys’ fees and expenses) incurred in connection with pursuing such payment and will pay interest on the amount of the payment at the prime rate of Bank of America (or its successors or assigns) in effect on the date the payment was payable in accordance with this Section 8.2(c). Parent will not be required to pay the Reverse Termination Fee pursuant to this Section 8.2(c) more than once. Except in the case of Parent’s or Merger Sub’s actual and intentional fraud in the making of any of its representations and warranties set forth in this Agreement or Willful Breach by Parent or Merger Sub of its covenants or agreements set forth in this Agreement, in the event that the Reverse Termination Fee is triggered and is paid pursuant to this Section 8.2(c), receipt of the Reverse Termination Fee shall be the sole and exclusive remedy of the Company and its Affiliates and Representatives against Parent and its Affiliates and Representatives under this Agreement or arising out of or related to this Agreement or the transactions contemplated hereby, and upon payment of such amount, neither Parent nor any of its Affiliates or Representatives shall have any further liability or obligation relating to or arising out of this Agreement or the transactions contemplated hereby, in each case whether based on contract, tort or strict liability, by the enforcement of any assessment, by any legal or equitable Proceeding, by virtue of any applicable Law or otherwise.

8.3 Fees and Expenses. Except as set forth in Section 6.4, Section 6.6 and Section 8.2, all fees, costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby will be paid by the party incurring such expenses whether or not the Merger is consummated.

8.5 Waiver. At any time prior to the Effective Time, either party hereto may (a) extend the time for the performance of any of the obligations or other acts of the other party hereto or (b) waive compliance with any of the agreements of the other party hereto or any conditions to its own obligations, in each case, only to the extent such obligations, agreements and conditions are intended for its benefit; provided, however, that any such extension or waiver will be binding upon a party hereto only if such extension or waiver is set forth in a writing executed by such party.

Any party hereto may by notice delivered in accordance with this Section 9.2 to the other parties hereto designate updated information for notices hereunder. Notice of any change to the address or any of the other details specified in or pursuant to this section will not be deemed to have been received until, and will be deemed to have been received upon, the later of the date specified in such notice or the date that is five Business Days after such notice would otherwise be deemed to have been received pursuant to this section. Nothing in this section will be deemed to constitute consent to the manner or address for service of process in connection with any legal Proceeding, including litigation arising out of or in connection with this Agreement.

9.3 Entire Agreement. This Agreement (including the Company Disclosure Letter, Annexes and Exhibits hereto and the documents and instruments referenced herein), together with the Voting Agreement, contains the entire agreement among the parties hereto with respect to the Merger and related transactions, and supersedes all prior agreements, written or oral, among the parties hereto with respect thereto, other than the Confidentiality Agreement, which will survive and remain in full force and effect (other than the “standstill” provisions, which will expire concurrently with the execution and delivery of this Agreement).

55

9.4 Governing Law. This Agreement and all actions arising under or in connection therewith will be governed by and construed in accordance with the Laws of the State of Delaware, regardless of any other Laws that might otherwise govern under applicable principles of conflicts of law.

9.5 Binding Effect; No Assignment; No Third-Party Beneficiaries.

(a) This Agreement will not be assigned by any of the parties hereto (whether by operation of Law or otherwise) without the prior written consent of the other parties hereto, except that (i) Merger Sub may assign, in its sole discretion and without the consent of any other party hereto, any or all of its rights, interests and obligations hereunder (A) to Parent, (B) to Parent and one or more direct or indirect wholly owned Subsidiaries of Parent or (C) to one or more direct or indirect wholly owned Subsidiaries of Parent (each, a “Merger Sub Assignee”) and (ii) Parent may assign, in its sole discretion and without the consent of any other party hereto, any or all of its rights, interests and obligations hereunder to one or more of its direct or indirect wholly owned Subsidiaries (each, a “Parent Assignee”). Any Merger Sub Assignee and any Parent Assignee may thereafter assign, in its sole discretion and without the consent of any other party hereto, any or all of its rights, interests and obligations hereunder to one or more additional Merger Sub Assignees or Parent Assignees, respectively; provided, however, that in connection with any assignment to any Merger Sub Assignee or Parent Assignee, Parent and Merger Sub (or the assignor), as applicable, will remain liable for the performance by Parent and Merger Sub (and such assignor, if applicable), as applicable, of their obligations hereunder. Subject to the preceding sentence, but without relieving any party hereto of any obligation hereunder, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties hereto and their respective successors and assigns.

(b) Other than Section 6.6, which will confer third-party beneficiary rights to the parties identified therein, nothing in this Agreement, express or implied, will confer upon any Person other than Parent, Merger Sub and the Company and their respective successors and permitted assigns any right, benefit or remedy of any nature by reason of this Agreement.

9.6 Counterparts and Signature. This Agreement may be executed in two or more counterparts (including by an electronic signature, electronic scan or electronic transmission in portable document format (.pdf), including (but not limited to) DocuSign, delivered by electronic mail), each of which will be deemed an original but all of which together will be considered one and the same agreement and will become effective when 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.

9.7 Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement will remain in full force and effect. Any provision of this Agreement held invalid or unenforceable only in part or degree will remain in full force and effect to the extent not held invalid or unenforceable. The parties hereto will replace such invalid or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable provision.

9.8 Submission to Jurisdiction; Waiver. Each of the Company, Parent and Merger Sub irrevocably agrees that any legal action or Proceeding with respect to this Agreement or the transactions contemplated hereby or for recognition and enforcement of any judgment in respect hereof brought by the other party hereto or its successors or assigns will be brought and determined in the Court of Chancery in the State of Delaware and, if such court declines jurisdiction, any other state court of the State of Delaware or the United States District Court for the District of Delaware, and each of the Company, Parent and Merger Sub hereby irrevocably submits with respect to any action or Proceeding for itself and in respect to its property, generally and unconditionally, to the exclusive jurisdiction of the aforesaid courts. Each of the Company, Parent and Merger Sub hereby irrevocably waives, and agrees not to assert, by way of motion, as a defense, counterclaim or otherwise, in any action or Proceeding with respect to this Agreement, (a) any claim that it is not personally subject to the jurisdiction of the

56

above-named courts for any reason other than the failure to lawfully serve process, (b) that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise), or (c) to the fullest extent permitted by Law, that (i) the suit, action or Proceeding in any such court is brought in an inconvenient forum, (ii) the venue of such suit, action or Proceeding is improper or (iii) this Agreement, or the subject matter hereof, is not enforceable in or by such courts.

9.9 Service of Process. Each party irrevocably consents to the service of process outside the territorial jurisdiction of the courts referred to in Section 9.8 in any such action or Proceeding by mailing copies thereof by registered United States mail, postage prepaid, return receipt requested, to its address as specified in or pursuant to Section 9.2. However, the foregoing will not limit the right of a party to effect service of process on the other party by any other legally available method.

9.10 Rules of Construction. Except where stated otherwise in this Agreement, the following rules of interpretation apply to this Agreement, (a) “either” and “or” are not exclusive and “include,” “includes” and “including” are not limiting, (b) “hereof,” “hereto,” “hereby,” “herein” and “hereunder” and words of similar import when used in this Agreement refer to this Agreement as a whole and not to any particular provision of this Agreement, (c) “extent” in the phrase “to the extent” means the degree to which a subject or other thing extends, and such phrase does not mean simply “if,” (d) descriptive headings, the table of defined terms and the table of contents are inserted for convenience only and do not affect in any way the meaning or interpretation of this Agreement, (e) definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms, (f) references to a Person are also to its permitted successors and assigns, (g) references to an “Article,” “Section,” “Exhibit,” “Annex” or “Schedule” refer to an Article or Section of, or an Exhibit, Annex or Schedule to, this Agreement, (h) references to “$” or otherwise to dollar amounts refer to the lawful currency of the United States, (i) references to a federal, state, local or foreign statute or Law shall mean such Law as from time to time amended, modified or supplemented, and include any rules, regulations and delegated legislation issued thereunder, (j) references to any communication by any Governmental Authority include communications by the staff of such Governmental Authority and (k) words denoting any gender will be deemed to include all genders and words denoting natural persons will be deemed to include business entities and vice versa. The language used in this Agreement will be deemed to be the language chosen by the parties hereto to express their mutual intent, and no rule of strict construction will be applied against any party hereto. No summary of this Agreement prepared by any party will affect the meaning or interpretation of this Agreement. The parties hereto agree that they have been represented by counsel during the negotiation and execution of this Agreement and, therefore, waive the application of any Law, regulation, holding or ruling of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document. Whenever the final day for performance of an obligation under this Agreement, other than an obligation under Section 5.2, falls on a day other than a Business Day, the time period for performance thereof will automatically be extended to the next day that is a Business Day. The term “made available to Parent” as it relates to materials provided to Parent shall be deemed to have been fulfilled if copies of the subject materials (i) were made available to Parent in the Data Room or through the Lorenz DocuBridge platform managed by the Company to which Parent has been granted access prior to the execution of this Agreement, in each case, by 5:00 p.m. (Pacific Standard Time) on March 11, 2023, (ii) were publicly available on EDGAR at least one Business Day prior to the date of this Agreement, or (iii) made available to Parent as provided in Section 9.10 of the Company Disclosure Letter. The covenants and obligations set forth in the Company Disclosure Letter are hereby incorporated into this Agreement, and each party shall perform such covenants and obligations as if fully set forth herein.

9.11 Specific Performance.

(a) The parties hereto acknowledge and agree that, in the event of any breach of this Agreement, irreparable harm would occur that monetary damages could not make whole. It is accordingly agreed that (i) each

57

party hereto will be entitled, in addition to any other remedy to which it may be entitled at law or in equity, to compel specific performance to prevent or restrain breaches or threatened breaches of this Agreement in any action without the posting of a bond or undertaking and (ii) the parties hereto will, and hereby do, waive, in any action for specific performance, the defense of adequacy of a remedy at law and any other objections to specific performance of this Agreement.

(b) Notwithstanding the parties’ rights to specific performance pursuant to Section 9.11(a), each party may pursue any other remedy available to it at law or in equity, including monetary damages.

9.12 No Waiver; Remedies Cumulative. No failure or delay by any party hereto in the exercise of any right hereunder will impair such right or be construed to be a waiver of, or acquiescence in, any breach of any representation, warranty or agreement herein, nor will any single or partial exercise of any such right preclude other or further exercise thereof or of any other right. All rights and remedies existing under this Agreement are cumulative to, and not exclusive to, and not exclusive of, any rights or remedies otherwise available.

9.13 Waiver of Jury Trial. EACH OF PARENT, COMPANY AND MERGER SUB HEREBY IRREVOCABLY WAIVES THE RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED IN CONTRACT, TORT OR OTHERWISE) ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY RELATED DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALINGS, STATEMENT OR ACTION RELATED HERETO OR THERETO. Each party to this Agreement certifies and acknowledges that (a) no Representative of any other party has represented, expressly or otherwise, that such other party would not seek to enforce the foregoing waiver in the event of a legal action, (b) such party has considered the implications of this waiver, (c) such party makes this waiver voluntarily, and (d) such party has been induced to enter into this Agreement by, among other things, the mutual waivers and certifications in this Section 9.13.

2. Agreement to Not Transfer the Covered Shares; No Inconsistent Arrangements

2.1. No Transfer of Covered Shares. Until the Expiration Time, the Advisor agrees that neither the Advisor nor any Stockholder shall Transfer or cause or permit the Transfer of any Covered Shares of any Stockholder, other than with the prior written consent of Parent; provided that the Advisor and any Stockholder may, without the consent of Parent, (i) Transfer Covered Shares to any controlled affiliate of the Advisor or any Stockholder, (ii) Transfer up to 4,000,000 Covered Shares in connection with a pro rata distribution of Covered Shares held by 667, L.P. to its partners, (iii) Transfer up to 1,400,000 Covered Shares to any charitable foundation or organization and (iv) subsequent to the date that the Company Required Vote is obtained, Transfer up to 4,700,000 Covered Shares in any calendar year to any other Person or Persons; provided, further, that any Transfer shall be permitted pursuant to clause (i) or (ii) above only if the transferee(s) of any such Transfer agrees in writing (reasonably satisfactory to Parent) prior to such Transfer to be bound by the terms and conditions of this Agreement with respect to the applicable Covered Shares as if such transferee(s) were the Advisor. Common Shares transferred pursuant to clause (iii) or (iv) of the preceding sentence shall cease to be Covered Shares after such Transfer. Any Transfer or attempted Transfer of any Covered Shares in violation of this Section 2.1 shall be null and void and of no effect whatsoever. If any involuntary Transfer of any of such Stockholder’s Covered Shares shall occur (including, but not limited to, a sale by such Stockholder’s trustee in any bankruptcy, or a sale to a purchaser at any creditor’s or court sale), the transferee (which term, as used herein, shall include any and all transferees and subsequent transferees of the initial transferee) shall, subject to applicable Law, take and hold such Covered Shares subject to all of the restrictions, obligations, liabilities and rights under this Agreement as if such transferee(s) were the Advisor.

2

Until the Expiration Time, the Advisor agrees that it shall not, and shall cause the Stockholders not to, take any action, in its capacity as the holder of voting and dispositive power over the Covered Shares, that would directly or indirectly have the effect of preventing, materially delaying or materially impairing the Advisor from performing any of its obligations under this Agreement or that would, or would reasonably be expected to, have the effect of preventing, materially delaying or materially impairing, the consummation of the Merger or the other transactions contemplated by the Merger Agreement or the performance by the Company of its obligations under the Merger Agreement.

3. Agreement to Vote the Covered Shares.

3.1. Voting Agreement. Until the Expiration Time, at every meeting of the Company’s stockholders at which any of the following matters are to be voted on (and at every adjournment or postponement thereof), and on any action or approval of the Company’s stockholders by written consent with respect to any of the following matters, the Advisor shall vote (including via proxy) all of the Covered Shares (or cause the holder of record on any applicable record date to vote (including via proxy) all of the Covered Shares) (a) in favor of any proposal to approve the adoption of the Merger Agreement and approve the Merger; and (b) against (1) any action or agreement that would reasonably be expected to result in any of the conditions to the Company’s obligations set forth in Section 7 under the Merger Agreement not being fulfilled or result in a breach of any covenant, representation or warranty or any other obligation or agreement of the Company contained in the Merger Agreement, or of the Advisor contained in this Agreement and (2) any Company Acquisition Proposal, or any agreement, transaction or other matter that is intended to, or would reasonably be expected to, impede or interfere with the consummation of the Merger and the other transactions contemplated by the Merger Agreement (clauses (a) and (b), the “Covered Proposals”).

4. Waiver of Certain Actions. The Advisor hereby agrees that (a) it shall not (and shall cause each Stockholder not to) commence or participate in, and (b) it shall take (and shall cause each Stockholder to take) all actions necessary to opt out of any class in any class action with respect to, in each of cases (a) and (b), any claim, derivative or otherwise, against Parent, Merger Sub, the Company or any of their respective Affiliates, successors, directors, managers or officers (i) challenging the validity of, or seeking to enjoin or delay the operation of, any provision of this Agreement or the Merger Agreement (including any claim seeking to enjoin or delay the closing of the Merger) or (ii) alleging a breach of any duty of the Company Board of Directors in connection with the Merger Agreement, this Agreement or the transactions contemplated thereby or hereby.

3

6.3. No Conflict; Consents.

a. The execution and delivery of this Agreement by the Advisor does not, and the performance by the Advisor of its obligations under this Agreement and the compliance by the Advisor with any provisions hereof does not and will not: (a) conflict with or violate any Laws, or (b) result in any breach of or constitute a default (or an event that with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, or result in the creation of a Lien on any of the Covered Shares of a Stockholder pursuant to any Contract or obligation to which the Advisor or any Stockholder is a party or by which the Advisor or any Stockholder is subject.

b. No consent, approval, order or authorization of, or registration, declaration or, except as required by the rules and regulations promulgated under the Exchange Act, filing with, any Governmental Entity or any other Person, is required by or with respect to the Advisor or any Stockholder in connection with the execution and delivery of this Agreement or the consummation by it of the transactions contemplated hereby.

4

6.4. Absence of Litigation. As of the date hereof, there is no legal action pending against, or, to the knowledge of the Advisor, threatened against or affecting the Advisor or any Stockholder that would reasonably be expected to impair the ability of the Advisor to perform its obligations hereunder or to consummate the transactions contemplated hereby on a timely basis.

7. Miscellaneous.

7.1. No Solicitation.

Nothing in this Section 7.5 will be deemed to constitute consent to the manner or address for service of process in connection with any legal Proceeding, including litigation arising out of or in connection with this Agreement.

7.6. Governing Law. This Agreement and all actions arising under or in connection therewith will be governed by and construed in accordance with the Laws of the State of Delaware, regardless of any other Laws that might otherwise govern under applicable principles of conflicts of law.

Each of the Company, Parent and the Advisor (on behalf of itself and the Stockholders) irrevocably agrees that any legal action or Proceeding with respect to this Agreement or the transactions contemplated hereby or for recognition and enforcement of any judgment in respect hereof brought by the other party hereto or its successors or assigns will be brought and determined in the Court of Chancery in the State of Delaware and, if such court declines jurisdiction, any other state court of the State of Delaware or the United States District Court for the District of Delaware, and each of the Company, Parent and the Advisor (on behalf of itself and the Stockholders) hereby irrevocably submits with respect to any action or Proceeding for itself and in respect to its property, generally and unconditionally, to the exclusive jurisdiction of the aforesaid courts. Each of the Company, Parent and the Advisor (on behalf of itself and the Stockholders) hereby irrevocably waives, and agrees not to assert, by way of motion, as a defense, counterclaim or otherwise, in any action or Proceeding with respect to this Agreement, (a) any claim that it is not personally subject to the jurisdiction of the above-named courts for any reason other than the failure to lawfully serve process, (b) that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise), or (c) to the fullest extent permitted by Law, that (i) the suit, action or Proceeding in any such court is brought in an inconvenient forum, (ii) the venue of such suit, action or Proceeding is improper or (iii) this Agreement, or the subject matter hereof, is not enforceable in or by such courts.

7.8. Service of Process. Each Party irrevocably consents to the service of process outside the territorial jurisdiction of the courts referred to in Section 7.7 in any such action or Proceeding by mailing copies thereof by registered United States mail, postage prepaid, return receipt requested, to its address as specified in or pursuant to Section 7.5. However, the foregoing will not limit the right of a Party to effect service of process on any other Party by any other legally available method.

7.9. Waiver of Jury Trial. EACH OF PARENT, COMPANY AND THE ADVISOR (ON BEHALF OF ITSELF AND THE STOCKHOLDERS) HEREBY IRREVOCABLY WAIVES THE RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED IN CONTRACT, TORT OR OTHERWISE) ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY RELATED DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALINGS, STATEMENT OR ACTION RELATED HERETO OR THERETO.

7

Each Party certifies and acknowledges that (a) no Representative of any other Party has represented, expressly or otherwise, that such other Party would not seek to enforce the foregoing waiver in the event of a legal action, (b) such Party has considered the implications of this waiver, (c) such Party makes this waiver voluntarily, and (d) such Party has been induced to enter into this Agreement by, among other things, the mutual waivers and certifications in this Section 7.9.

7.10. No Waiver; Remedies Cumulative. No failure or delay by any Party in the exercise of any right hereunder will impair such right or be construed to be a waiver of, or acquiescence in, any breach of any representation, warranty or agreement herein, nor will any single or partial exercise of any such right preclude other or further exercise thereof or of any other right. All rights and remedies existing under this Agreement are cumulative to, and not exclusive to, and not exclusive of, any rights or remedies otherwise available.

7.11. Documentation and Information. The Advisor shall not, and shall cause its controlled Affiliates (including the Stockholders) not to, make any public announcement regarding this Agreement or the transactions contemplated hereby without the prior written consent of Parent (such consent not to be unreasonably withheld, conditioned or delayed), except as may be required by applicable Law (provided that reasonable notice of any such disclosure will be provided to Parent, and the Advisor will consider in good faith the reasonable comments of Parent with respect to such disclosure and otherwise cooperate with Parent in obtaining confidential treatment with respect to such disclosure if requested by Parent at Parent’s sole cost and expense). The Advisor consents to and authorizes (and hereby agrees that the Stockholders consent and authorize) the publication and disclosure by Parent and the Company of the Advisor’s and the Stockholders’ identity and holding of the Covered Shares, and the terms of this Agreement (including the disclosure of this Agreement), in any press release, the Proxy Statement and any other disclosure document required in connection with the Merger Agreement, the Merger and the other transactions contemplated by the Merger Agreement (provided that reasonable notice of any such disclosure will be provided to the Advisor, and Parent will consider in good faith the reasonable comments of the Advisor with respect to such disclosure), and the Advisor acknowledges (and hereby agrees that the Stockholders acknowledge) that Parent and the Company may, in their sole discretion, file this Agreement or a form hereof with the SEC or any other Governmental Authority or securities exchange. The Advisor agrees to promptly give the Company and Parent any information it may reasonably require for the preparation of any such disclosure documents, and the Advisor agrees to promptly notify the Company and Parent of any required corrections with respect to any information supplied by the Advisor specifically for use in any such disclosure document, if and to the extent that any such information shall have become false or misleading in any material respect.

7.12. Further Assurances. The Advisor agrees that it shall, and shall cause the Stockholders to, from time to time, at the reasonable request of Parent and without further consideration, execute and deliver such additional documents and take all such further action as may be reasonable required to consummate and make effective, in the most expeditious manner practicable, the transactions contemplated by this Agreement.

7.13. Stop Transfer Instructions. At all times commencing with the execution and delivery of this Agreement and continuing until the Expiration Time, in furtherance of this Agreement, the Advisor, on behalf of itself and the Stockholders, hereby authorizes the Company or its counsel to notify the Company’s transfer agent that there is a stop transfer order with respect to the Covered Shares (and that this Agreement places limits on the voting and transfer of the Covered Shares), subject to the provisions hereof and provided that any such stop transfer order and notice will immediately be withdrawn and terminated by the Company following the Expiration Time; provided, that such stop transfer order will not be applicable to any Transfer effectuated in compliance with Section 2.1 hereof.

8

7.14. Specific Performance. The Parties acknowledge and agree that, in the event of any breach of this Agreement, irreparable harm would occur that monetary damages could not make whole. It is accordingly agreed that (i) each Party will be entitled, in addition to any other remedy to which it may be entitled at law or in equity, to compel specific performance to prevent or restrain breaches or threatened breaches of this Agreement in any action without the posting of a bond or undertaking and (ii) the Parties will, and hereby do, waive, in any action for specific performance, the defense of adequacy of a remedy at law and any other objections to specific performance of this Agreement. Notwithstanding the Parties’ rights to specific performance pursuant to Section 7.14, each Party may pursue any other remedy available to it at law or in equity, including monetary damages.

7.15. Indemnification. From and after the Effective Time, Parent will indemnify, defend and hold harmless the Advisor and the Stockholders against any costs or expenses (including attorneys’ fees and expenses), amounts paid in settlement, judgments, fines, losses, claims, damages or liabilities incurred by any of them in connection with, arising out of or otherwise related to any third-party claim, whether asserted or claimed prior to, at or after the Effective Time, arising from or in connection with the execution of this Agreement and the transactions contemplated hereby, including the Merger.

7.16. Entire Agreement. This Agreement, including the Schedules hereto, constitutes the entire agreement among the Parties, and supersedes all prior agreements and understandings, both written and oral, among the Parties with respect to such subject matter. For the avoidance of doubt, nothing in this Agreement shall be deemed to amend, alter or modify, in any respect, any of the provisions of the Merger Agreement.

7.17. Interpretation. Except where stated otherwise in this Agreement, the following rules of interpretation apply to this Agreement: (a) “either” and “or” are not exclusive and “include,” “includes” and “including” are not limiting, (b) “hereof,” “hereto,” “hereby,” “herein” and “hereunder” and words of similar import when used in this Agreement refer to this Agreement as a whole and not to any particular provision of this Agreement, (c) “extent” in the phrase “to the extent” means the degree to which a subject or other thing extends, and such phrase does not mean simply “if,” (d) descriptive headings are inserted for convenience only and do not affect in any way the meaning or interpretation of this Agreement, (e) definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms, (f) references to a Person are also to its permitted successors and assigns, (g) references to a “Section,” or “Schedule” refer to a Section of, or a Schedule to, this Agreement, (h) references to a federal, state, local or foreign statute or Law shall mean such Law as from time to time amended, modified or supplemented, and include any rules, regulations and delegated legislation issued thereunder, and (i) words denoting any gender will be deemed to include all genders and words denoting natural persons will be deemed to include business entities and vice versa. The language used in this Agreement will be deemed to be the language chosen by the Parties to express their mutual intent, and no rule of strict construction will be applied against any Party. No summary of this Agreement prepared by any Party will affect the meaning or interpretation of this Agreement. The Parties agree that they have been represented by counsel during the negotiation and execution of this Agreement and, therefore, waive the application of any Law, regulation, holding or ruling of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document. Whenever the final day for performance of an obligation under this Agreement, falls on a day other than a Business Day, the time period for performance thereof will automatically be extended to the next day that is a Business Day.

9

7.18. Assignment; Third-Party Beneficiaries. This Agreement will not be assigned by any of the Parties (whether by operation of Law or otherwise) without the prior written consent of the other Parties. Subject to the preceding sentence, but without relieving any Party of any obligation hereunder, this Agreement will be binding upon, inure to the benefit of and be enforceable by the Parties and their respective successors and assigns. Nothing in this Agreement, express or implied, will confer upon any Person other than the Parties and their respective successors and permitted assigns any right, benefit or remedy of any nature by reason of this Agreement.

7.19. Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement will remain in full force and effect. Any provision of this Agreement held invalid or unenforceable only in part or degree will remain in full force and effect to the extent not held invalid or unenforceable. The Parties will replace such invalid or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable provision.

7.20. Non-Survival of Representations and Warranties. None of the representations and warranties in this Agreement shall survive the Effective Time.

7.21. Termination. This Agreement shall automatically terminate without further action by any of the Parties and shall have no further force or effect as of the Expiration Time; provided that the provisions of Sections 7.4, 7.5, 7.6, 7.7, 7.8, 7.9, 7.10, 7.15, 7.17, 7.20 and 7.21 shall survive any such termination. Notwithstanding the foregoing, termination of this Agreement shall not prevent any Party from seeking any remedies (at Law or in equity) against any other Party for that Party’s breach of any of the terms of this Agreement prior to the date of termination.

7.22. Counterparts and Signature. This Agreement may be executed in two or more counterparts (including by an electronic signature, electronic scan or electronic transmission in portable document format (.pdf), including (but not limited to) DocuSign, delivered by electronic mail), each of which will be deemed an original but all of which together will be considered one and the same agreement and will become effective when counterparts have been signed by each of the Parties and delivered to the other Parties, it being understood that all Parties need not sign the same counterpart.

7.23. No Ownership Interest. Nothing contained in this Agreement shall be deemed to vest in Parent or the Company any direct or indirect ownership or incidence of ownership of or with respect to the Covered Shares. All rights, ownership and economic benefits of and relating to the Covered Shares shall remain vested in and belong to the Advisor and the Stockholders, as applicable, and Parent shall have no authority to direct the Advisor in the voting or disposition of any Covered Shares, expect as specifically provided herein.

EXECUTION

[David Epstein/Roger D. Dansey, M.D.]

At the address on file with the Company

Dear [David/Roger]:

This letter agreement (this “Agreement”) confirms the understanding between you and Seagen Inc. (the “Company”) regarding certain payments that you may become entitled to receive in connection with the proposed acquisition (the “Acquisition”) of the Company by Pfizer Inc. (“Parent”), pursuant to that certain Agreement and Plan of Merger, dated as of the date hereof, by and among Parent, the Company, and Aris Merger Sub, Inc. (the “Merger Agreement”), and amends your [Amended and Restated] Executive Employment Agreement with the Company, dated as of November 8, 2022 (the “Employment Agreement”). Capitalized terms used but not otherwise defined in this Agreement have the meanings given to such terms in the Employment Agreement. If (a) the Merger Agreement terminates pursuant to its terms or (b) your employment with the Company terminates due to a Termination for Cause or a Voluntary Termination prior to the Closing (as defined in the Merger Agreement), this Agreement will terminate and be of no force or effect.

1. Certain Taxes

Notwithstanding anything to the contrary in Section 6.1 of the Employment Agreement, in the event that it shall be determined that any payment, award, benefit or distribution (or any acceleration of any payment, award, benefit or distribution) by the Company or any of its affiliated entities (including their respective successors) to or for your benefit in connection with the Acquisition (determined without regard to any additional payments required under this Section 1) (the “Payments”) would be subject to the excise tax imposed by Section 4999 of the Internal Revenue Code of 1986, as amended (the “Code”), or any interest or penalties are incurred by you with respect to such excise tax (such excise tax, together with any such interest and penalties, the “Excise Tax”), then the Company shall pay you an additional payment (which, for this purpose, includes withholding and remittance of taxes by Parent or the Company on your behalf) (a “Reimbursement Payment”) in an amount such that after payment by you of all taxes (including, without limitation, any income taxes and any interest and penalties imposed with respect to, and any excise tax imposed upon, the Reimbursement Payment), you retain an amount of the Reimbursement Payment equal to the Excise Tax imposed upon the Payments. For purposes of determining the amount of the Reimbursement Payment, you shall be deemed to (i) pay federal income taxes at the highest marginal rates of federal income taxation for the calendar year in which the Reimbursement Payment is to be made and (ii) pay applicable state and local income taxes at the highest marginal rate of taxation for the calendar year in which the Reimbursement Payment is to be made, net of the maximum reduction, if any, in federal income taxes which could be obtained from deduction of such state and local taxes. The Reimbursement Payment payable with respect to any Payment will be made as soon as reasonably practicable following the determination by 280G Counsel (as defined below) that the Reimbursement Payment is due (and, subject to Section 2, in no event later than 60 days following such Payment).

Notwithstanding the foregoing provisions of this Section 1, if it is determined that you are entitled to a Reimbursement Payment, but that the Parachute Value of all of your Payments does not exceed 105% of your Safe Harbor Amount, then no Reimbursement Payment shall be made to you and the Payments shall be reduced so that the Parachute Value of all of your Payments, in the aggregate, equals the Safe Harbor Amount. The reduction of the Payments, if applicable, shall be made in the order set forth in Section 6.1 of the Employment Agreement. For purposes of this Agreement, “Parachute Value” of a Payment means the present value, as of the date of the Closing, of the portion of such Payment that constitutes a “parachute payment” under Section 280G(b)(2), as determined by 280G Counsel for purposes of determining whether and to what extent the Excise Tax will apply to such Payment; and “Safe Harbor Amount” means 2.99 times your “base amount,” within the meaning of Section 280G(b)(3) of the Code.

2. Determinations

You and the Company agree that for purposes of determining whether any of the Payments will be subject to the Excise Tax and the amount of such Excise Tax, Golden Parachute Tax Solutions LLC shall perform and prepare all calculations and make all accounting determinations and Parent’s legal counsel shall make all legal determinations (the foregoing advisors, collectively, the “280G Counsel”). For purposes of making such determinations, 280G Counsel may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code, and will take into account the value of any reasonable compensation for services to be rendered by you before or after the Acquisition, including the valuation any noncompetition provisions that apply to you as of the date hereof (including those set forth in Section 3 of this Agreement). As a condition to this Agreement, you agree that you shall cooperate in the valuation of any such services, including the valuation of any noncompetition provisions, and to cooperate with any other reasonable requests by the Company to mitigate the impact of Sections 280G and 4999 of the Code (which you agree includes, if requested by Parent, the accelerated vesting into 2023 of time-vesting restricted stock units that are scheduled to vest on or prior to the Outside Date (as defined in the Merger Agreement) (subject to a top up for any net after tax shortfall arising due to the withholding of shares upon early settlement to pay applicable taxes at a price per share less than the closing price of a share of the Company’s common stock on the original vesting date or, if the Closing occurs before the original vesting date, $229/share), [payment of your relocation payment in 2023,]¹ payment in 2023 of your annual bonus in respect of 2023, the payout of accrued vacation and other paid time off in 2023, and if additional mitigation is necessary, the parties shall consider in good faith the exercise of stock options in 2023); provided, for the avoidance of doubt, that no such actions shall increase the amount of the Excise Tax payable by you or result in any such payment being subject to any tax imposed under Section 409A. You and the Company shall furnish to 280G Counsel such information and documents as 280G Counsel may reasonably request in order to make a determination under this Agreement. The Company shall bear all costs 280G Counsel may reasonably incur in connection with any calculations contemplated by this Agreement. 280G Counsel shall provide detailed supporting calculations both to you and the Company within 15 business days of the receipt of notice from you or the Company that there has been a Payment, or such earlier time as is requested by the Company. The determinations of 280G Counsel shall be binding upon you and the Company, and neither you nor the Company shall take a tax reporting position that is inconsistent with the determination of 280G Counsel.

¹  Note to Draft: For David only.

-2-

As a condition to this Agreement, you shall notify the Company in writing of any claim by the Internal Revenue Service that, if successful, would require the payment by the Company of the Reimbursement Payment. Such notification shall be given as soon as practicable, but no later than five (5) business days after you have actual knowledge of such claim. You shall not pay such claim and the Company shall control the defense of any such claims or disputes, bear all costs related to the defense thereof. As a condition to the foregoing, you shall (i) provide to the Company any information requested by the Company relating to such dispute, (ii) take such action in connection with contesting such dispute as the Company shall reasonably request from time to time, including, without limitation, accepting legal representation with respect to such claim by an attorney reasonably selected by the Company, and (iii) cooperate with the Company in good faith in order effectively to defend such dispute. The Company’s control and payment of the associated costs of the contest shall be limited to issues with respect to which the Reimbursement Payment would be payable hereunder.

As a result of the uncertainty in the application of Section 4999 of the Code at the time of the Determination, it is possible that Reimbursement Payments which will not have been made by the Company should have been made (“Underpayment”), consistent with the calculations required to be made hereunder. In the event that, after the Company exhausts its remedies under the immediately preceding paragraph, the amount of the Reimbursement Payment is less than the amount ultimately determined necessary to reimburse you for your Excise Tax, 280G Counsel shall determine the amount of the Underpayment that has occurred and any such Underpayment (together with interest at the rate provided in Section 1274(b)(2)(B) of the Code) shall be promptly paid by the Company to or for the benefit of you. If, after receipt of a Reimbursement Payment, you become entitled to receive any refund with respect to the Excise Tax to which such Reimbursement Payment relates, you shall promptly pay to the Company the amount of any such refund (together with interest at the rate provided in Section 1274(b)(2)(B) of the Code).

3. Other Terms

You acknowledge and agree that the Proprietary Information and Inventions Agreement between you and the Company (the “PIIA”) shall remain in full force and in effect in accordance its terms, and your obligations and duties thereunder are not in any way superseded by this Agreement; provided that, for clarity, the non-competition covenant set forth in Exhibit E shall continue to apply in the event of your termination without Cause or a Voluntary Termination.

The validity, interpretation, construction and performance of this Agreement shall in all respects be governed by the laws of Washington, without reference to principles of conflict of law, and will be binding on any successor to the Company. This Agreement is intended to comply with the requirements of Section 409A of the Code (to the extent applicable) and shall be interpreted, operated and administered accordingly. Each payment under this Agreement will be treated as a separate payment for purposes of Section 409A of the Code. As used in this Agreement, “Company” shall mean the Company as hereinbefore defined and any successor to its business and/or assets as aforesaid which assumes this Agreement by operation of law, or otherwise (including, after the Closing, Parent and its affiliates).

4. Counterparts.

This Agreement may be executed in one or more counterparts, each of which shall be deemed to be an original but all of which together will constitute one and the same agreement.

Exhibit 99.1

        

Pfizer Invests $43 Billion to Battle Cancer

• Pfizer to acquire Seagen for $229 per Seagen share in cash, for a total enterprise value of approximately $43 billion

• Proposed combination enhances Pfizer’s position as a leading company in Oncology

• Seagen’s medicines, late-stage development programs and pioneering expertise in Antibody-Drug Conjugates (ADCs) strongly complement Pfizer’s Oncology portfolio

• Seagen expected to contribute more than $10 billion in risk-adjusted revenues in 2030

• Pfizer and Seagen to hold analyst and investor call at 8 a.m. EDT today

NEW YORK and BOTHELL, Washington, March 13, 2023 – Pfizer Inc. (NYSE: PFE) and Seagen Inc. (Nasdaq: SGEN) today announced that they have entered into a definitive merger agreement under which Pfizer will acquire Seagen, a global biotechnology company that discovers, develops and commercializes transformative cancer medicines, for $229 in cash per Seagen share for a total enterprise value of $43 billion. The Boards of Directors of both companies have unanimously approved the transaction.

“Pfizer is deploying its financial resources to advance the battle against cancer, a leading cause of death worldwide with a significant impact on public health,” said Dr. Albert Bourla, Pfizer Chairman and Chief Executive Officer. “Together, Pfizer and Seagen seek to accelerate the next generation of cancer breakthroughs and bring new solutions to patients by combining the power of Seagen’s antibody-drug conjugate (ADC) technology with the scale and strength of Pfizer’s capabilities and expertise. Oncology continues to be the largest growth driver in global medicine, and this acquisition will enhance Pfizer’s position in this important space and contribute meaningfully to the achievement of Pfizer’s near- and long-term financial goals.”

Seagen expects to generate approximately $2.2 billion of revenue in 2023¹, representing 12% year-over-year growth, from its four in-line medicines, royalties and collaboration and license agreements. When combining the expected strong growth trajectories for these medicines with candidates that could emerge from Seagen’s pipeline, subject to clinical trial and regulatory success, Pfizer believes Seagen could contribute more than $10 billion in risk-adjusted revenues in 2030, with potential significant growth beyond 2030.

Seagen is a pioneer in ADC technology, with four of the twelve total FDA-approved and marketed ADCs using its technology industry-wide. ADCs are a transformative modality that is emerging as a powerful tool across a broad range of cancers designed to preferentially kill cancer cells and limit off-target toxicities. Seagen has developed a leadership position in ADC technologies since its founding 25 years ago, with groundbreaking and proprietary technology that is positioned for significant growth in 2023 and beyond. Seagen’s portfolio includes four approved medicines² that are first- or best-in-class in their respective indications across solid tumors and hematologic malignancies, including three ADCs: ADCETRIS^® (brentuximab vedotin), PADCEV^® (enfortumab vedotin), and TIVDAK^® (tisotumab vedotin). The company also commercializes TUKYSA^® (tucatinib). Clinical development programs are ongoing for each of these medicines for potential new tumor types or expanded indications in earlier lines of therapy, with catalysts expected annually through 2027.

Seagen is also poised to expand the impact of its therapeutic approach with its broad and deep pipeline that includes eleven new molecular entities, many with the potential to treat large patient populations and all with global commercial rights.³ The proposed acquisition is also expected to enable for combination potential across both the Seagen and Pfizer pipelines and will leverage Pfizer’s protein engineering and medicinal chemistry capabilities to advance Seagen’s ADC technology to unlock potential novel target combinations and next-generation biologics.

Seagen is also advancing innovative technologies capable of potentially generating multiple Investigational New Drug Applications (INDs), including next-generation linker/payload technologies for ADCs and other innovative antibody platforms that directly engage the immune system to destroy tumors, such as bi-specific antibodies.

“Pfizer shares our steadfast commitment to patients, and this combination is a testament to the passion, dedication and talent of the Seagen team to achieve our mission to discover, develop, and commercialize transformative cancer medicines that make a meaningful difference in people’s lives,” said David Epstein, Seagen Chief Executive Officer. “The proposed combination with Pfizer is the right next step for Seagen to further its strategy, and this compelling transaction will deliver significant and immediate value to our stockholders and provide new opportunities for our colleagues as part of a larger science-driven, patient-centric, global company.”

2

Today, Pfizer Oncology has an industry-leading portfolio of 24 approved innovative cancer medicines that generated $12.1 billion in 2022 revenues, including the best-selling therapies for metastatic breast cancer and prostate cancer. Pfizer’s in-line portfolio is focused on four broad, key areas: breast cancer, genitourinary cancer, hematology and precision medicine, complemented by an extensive pipeline of 33 programs in clinical development. The proposed combination with Seagen would double Pfizer’s early-stage oncology clinical pipeline.

“Over the past decade we’ve taken bold new approaches to translating scientific research into effective medicines for people living with cancer, and we have pioneered several breakthroughs in breast cancer, genitourinary cancer, hematological malignancies and precision medicine,” said Chris Boshoff, Chief Development Officer Oncology and Rare Disease, Pfizer. “The addition of Seagen’s world-leading ADC technology will position us at the forefront of innovative cancer care, and strongly complements our existing portfolio across both solid tumors and hematologic malignancies. We believe the combination of our teams, and respective areas of strength and global footprints will allow us to realize Seagen’s potential and advance even more potential breakthroughs to patients with cancer.”

Pfizer expects to finance the transaction substantially through $31 billion of new, long-term debt, and the balance from a combination of short-term financing and existing cash. The transaction is expected to be neutral to slightly accretive to adjusted diluted earnings per share (EPS)⁴ in the third to fourth full year post close. Pfizer expects to achieve nearly $1 billion in cost efficiencies in the third full year after the completion of the transaction.

The companies expect to complete the transaction in late 2023 or early 2024, subject to fulfillment of customary closing conditions, including approval of Seagen’s stockholders and receipt of required regulatory approvals.

Pfizer’s financial advisor for the transaction is Guggenheim Securities, LLC, with Wachtell, Lipton, Rosen & Katz acting as Pfizer’s legal advisor. Centerview Partners LLC is serving as Seagen’s financial advisor and provided a fairness opinion to Seagen’s Board of Directors with Sullivan & Cromwell LLP serving as its legal advisor. MTS Health Partners also provided financial advice to Seagen.

Footnotes (Page 2 of 3) (1) Seagen selected commercialization territories: ® • Adcetris (brentuximab vedotin) – U.S. & Canada (collaboration with Takeda) ® • Padcev (enfortumab vedotin) – U.S. (co-commercialization with Astellas), Canada and Latin America (the latter through distributor Adium). Seagen records in-market sales in North and South America. Astellas records in-market sales in ROW. Both parties equally share profits in U.S., Canada and major markets in Europe. In other countries, the commercializing company will pay the other royalties on a rate intended to approximate equal profit share. ® • Tukysa (tucatinib) – U.S., Canada, Europe (collaboration with Merck, in Europe through distributors Swixx and Genesis). ® • Tivdak (tisotumab vedotin) - Seagen will commercialize in U.S., Canada and Mexico. Genmab will commercialize in other regions excluding China. Zai Lab has development and commercialization rights in mainland China, Hong Kong, Macau and Taiwan. • Disitamab Vedotin (DV): Global rights outside of RemeGen territories (RemeGen retains rights to Asia, excluding Japan and Singapore). RemeGen is responsible for clinical developments in its regions, which can include proportional funding for global registration enabling trials. (2) Pfizer selected commercialization and development rights: ® • Xtandi (enzalutamide) is developed and marketed in the U.S. in collaboration with Astellas. • Orgovyx™ (relugolix) is co-developed and commercialized in the U.S. in collaboration with Myovant Sciences. ® • Bavencio (avelumab) is co-developed and co-commercialized in collaboration with Merck KGaA, Darmstadt, Germany. • Pfizer has exclusive rights to Braftovi® (encorafenib) and Mektovi® (binimetinib) in the U.S. and Canada.

Footnotes (Page 3 of 3) (3) Adjusted income and Adjusted diluted EPS are defined as U.S. GAAP net income attributable to Pfizer Inc. shareholders and Reported diluted EPS attributable to Pfizer Inc. common shareholders before the impact of amortization of intangible assets, certain acquisition-related items, discontinued operations and certain significant items. Pfizer does not provide guidance for GAAP Reported financial measures (other than revenues) or a reconciliation of forward-looking non- GAAP financial measures to the most directly comparable GAAP Reported financial measures on a forward-looking basis because it is unable to predict with reasonable certainty the ultimate outcome of unusual gains and losses, certain acquisition-related expenses, gains and losses from equity securities, actuarial gains and losses from pension and postretirement plan remeasurements, potential future asset impairments and pending litigation without unreasonable effort. These items are uncertain, depend on various factors, and could have a material impact on GAAP Reported results for the guidance period. Pfizer calculates projections regarding the expected dilutive and accretive impact of the potential acquisition, based on internal forecasts of Adjusted income and Adjusted diluted earnings per share (Adjusted diluted EPS), which forecasts are non-GAAP financial measures derived by excluding certain amounts that would be included in GAAP calculations. These dilution/accretion projections should not be considered a substitute for GAAP measures. Such items can have a substantial impact on GAAP measures of financial performance. The Adjusted income and Adjusted diluted EPS measures are not, and should not be viewed as, a substitute for U.S. GAAP net income and Reported diluted EPS. For more information on the Adjusted diluted EPS measure, see the Non- GAAP Financial Measure: Adjusted Income section of Management’s Discussion and Analysis of Financial Condition and Results of Operations in Pfizer’s 2022 Annual Report on Form 10-K. 20
