Item 1.01 Entry into a Material Definitive Agreement.

On March 1, 2020, Forty Seven, Inc., a Delaware corporation (the “Company” or “Forty Seven”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), by and among the Company, Gilead Sciences, Inc., a Delaware corporation (“Parent” or “Gilead”), and Toro Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Parent (“Purchaser”).

Pursuant to the Merger Agreement, and upon the terms and subject to the conditions thereof, Parent has agreed to cause Purchaser to commence a tender offer (the “Offer”) to purchase all of the outstanding shares of common stock of the Company (the “Shares”), par value $0.0001 per share, other than any Shares held immediately prior to the effective time of the Merger (as defined below) by the Company (or held in the Company’s treasury) and any Shares held immediately prior to the effective time of the Merger by Parent, Purchaser or any other direct or indirect wholly owned subsidiary of Parent, at a price of $95.50 per Share (the “Offer Price”), net to the seller in cash, without interest and subject to any required withholding of taxes.

The Offer will initially remain open for 20 business days from the date of commencement of the Offer. If at the scheduled expiration time of the Offer any of the conditions to the Offer have not been satisfied (unless such condition is waivable by Purchaser or Parent and has been waived), Parent will cause Purchaser to, extend the Offer to permit the satisfaction of all Offer conditions.

The obligation of Purchaser to accept for payment, and pay for, Shares validly tendered (and not validly withdrawn) pursuant to the Offer is subject to satisfaction or waiver, to the extent permitted under applicable legal requirements, of customary conditions, including (i) there being validly tendered and not validly withdrawn Shares that, considered together with all other Shares (if any) beneficially owned by Parent and its affiliates, represent one more Share than 50% of the sum of (x) the total number of Shares outstanding at the expiration of the Offer, plus (y) the total number of Shares the Company would be required to issue upon conversion, settlement, exchange or exercise of all options, warrants, rights or securities vested and outstanding at the expiration of the Offer that are convertible, exchangeable or exercisable into Shares (whether then outstanding or for which the conversion, settlement, exchange or exercise date has already occurred, but in any event without duplication), (ii) the expiration or termination of the waiting period (or any extension thereof) applicable to the Offer under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), (iii) the absence of any law or order in any jurisdiction in which Parent or the Company has material business operations prohibiting the consummation of the Offer or the Merger, (iv) the accuracy of the Company’s representations and warranties (subject to customary materiality qualifiers), (v) the Company’s compliance or performance in all material respects of its obligations, covenants and agreements it is required to comply with or perform at or prior to the expiration of the Offer, and (vi) the absence, since the date of the Merger Agreement, of any change, circumstance, condition, development, effect, event, occurrence or state of facts which, individually or in the aggregate, has had, or would reasonably be expected to have, a Material Adverse Effect (as defined in the Merger Agreement) that is continuing.

Following the consummation of the Offer and subject to the terms and conditions of the Merger Agreement, Purchaser will be merged with and into the Company (the “Merger”) pursuant to Section 251(h) of the General Corporation Law of the State of Delaware (the “DGCL”), with the Company continuing as the surviving corporation in the Merger. At the effective time of the Merger, each Share, including any Shares subject to vesting or employment based forfeiture conditions (“Restricted Shares”) (other than (i) Shares held by the Company (or held in the Company’s treasury), (ii) Shares held by Parent, Purchaser, or any other direct or indirect wholly owned subsidiary of Parent and (iii) Shares held by stockholders who have properly exercised and perfected their demands for appraisal of such Shares in accordance with the DGCL and have neither withdrawn nor lost such rights prior to the effective time of the Merger) will be converted into the right to receive an amount in cash equal to the Offer Price, without interest, without regard to any vesting or employment based forfeiture conditions which were applicable to the corresponding Restricted Shares, and subject to any required withholding of taxes.

The Merger Agreement includes customary representations, warranties and covenants of the Company, Parent and Purchaser.

The Company has agreed to customary “no-shop” restrictions on its ability to solicit alternative acquisition proposals from third parties and engage in discussions or negotiations with third parties regarding alternative acquisition proposals. Notwithstanding these restrictions, the Company may under certain circumstances provide, pursuant to an acceptable confidentiality agreement, information (including non-public information) to and engage in or otherwise participate in discussions or negotiations with third parties with respect to a bona fide written alternative acquisition proposal that the board of directors of the Company has determined in good faith, after consultation with its financial advisor and outside legal counsel, constitutes or would reasonably be expected to result in a Superior Offer (as defined in the Merger Agreement) and that failure to take such action would be inconsistent with the board’s fiduciary duties under applicable legal requirements. The Merger Agreement also requires that the Company’s board of directors recommend that the stockholders of the Company accept the Offer and tender their Shares to Purchaser pursuant to the Offer and not, among other things, (i) withdraw or withhold (or modify or qualify in a manner adverse to Parent or Purchaser), or publicly propose to withdraw or withhold (or modify or qualify in a

manner adverse to Parent or Purchaser), the Company’s board of director recommendation, (ii) adopt, approve, recommend or declare advisable, or publicly propose to adopt, approve, recommend or declare advisable, any alternative acquisition proposal, (iii) fail to publicly affirm its recommendation within three business days following Parent’s written request after the announcement of an alternative acquisition proposal (subject to certain limitations related to serial requests and during any matching rights period), (iv) fail to publicly reaffirm the Company’s board of director recommendation and recommend that the Company’s stockholders reject any competing third-party tender or exchange offer within ten days after commencement or (v) fail to include the recommendation in the Company’s Tender Offer Solicitation/Recommendation Statement on Schedule 14D-9 when filed with the U.S. Securities and Exchange Commission (the “SEC”) or disseminated to the Company’s stockholders. Notwithstanding these restrictions, the board of directors of the Company is permitted, subject to the terms and conditions set forth in the Merger Agreement, to change its recommendation and terminate the Merger Agreement to accept a Superior Offer or change its recommendation in response to an Intervening Event (as defined in the Merger Agreement), subject in each case to certain matching rights in favor of Parent.

The Merger Agreement contains certain termination rights for both the Company and Parent, including if (i) the closing has not occurred prior to June 1, 2020, but subject to an automatic 90-day extension if the condition related to the expiration or termination of the waiting period under the HSR Act has not been satisfied or waived, (ii) if consummation of the Offer or the Merger is legally prohibited or enjoined or (iii) if there has been a breach by the other party that is not cured such that, in the case of the Company, the applicable Offer conditions would not be satisfied or, in the case of Parent, the consummation of the Offer or the Merger would be prevented. The Merger Agreement may also be terminated (i) by the Company, subject to the terms and conditions set forth in the Merger Agreement, to accept a Superior Offer and (ii) by Parent if the board of directors of the Company has effected a Company Adverse Change Recommendation (as defined in the Merger Agreement). Upon termination of the Merger Agreement (i) by the Company to accept a Superior Offer or (ii) by Parent following a Company Adverse Change Recommendation, the Company will be required to pay Parent a termination fee of $160 million. Under certain additional circumstances described in the Merger Agreement, the Company must also pay Parent such termination fee if the Merger Agreement is terminated and, within 12 months following such termination, the Company recommends or enters into certain alternative acquisition arrangements and such acquisition is subsequently consummated.

The foregoing description of the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is filed as Exhibit 2.1 hereto and which is incorporated herein by reference. The Merger Agreement has been filed to provide information to investors regarding its terms. It is not intended to provide any other factual information about the Company, Parent or Purchaser, their respective businesses, or the actual conduct of their respective businesses during the period prior to the consummation of the Offer, the Merger or the other transactions contemplated by the Merger Agreement. The Merger Agreement and this summary should not be relied upon as disclosure about the Company or Parent. None of the Company’s stockholders or any other third parties should rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or conditions of the Company, Parent, Purchaser or any of their respective subsidiaries or affiliates. The Merger Agreement contains representations and warranties that are the product of negotiations among the parties thereto and that the parties made to, and solely for the benefit of, each other as of specified dates. The assertions embodied in those representations and warranties are subject to qualifications and limitations agreed to by the respective parties and are also qualified in important part by confidential disclosure schedules delivered in connection with the Merger Agreement. The representations and warranties may have been made for the purpose of allocating contractual risk between the parties to the agreements instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors.

Item 8.01 Other Events.

On March 2, 2020, the Company and Parent issued a joint press release announcing the Merger Agreement, a copy of which is filed as Exhibit 99.1 and incorporated herein by reference.

Each of Parent, Purchaser and the Company agrees to respond promptly to any comments (including oral comments) of the SEC or its staff and to promptly correct any information provided by it for use in the Schedule 14D-9 if and to the extent that such information shall have become false or misleading in any material respect, and the Company further agrees to take all steps necessary to promptly cause the Schedule 14D-9 as so corrected to be filed with the SEC and to be disseminated to holders of Shares, in each case as and to the extent required by applicable Legal Requirements.

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

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

2.4    Certificate of Incorporation and Bylaws; Directors and Officers.

(a)    As of the Effective Time, the certificate of incorporation of the Company shall, by virtue of the Merger and without any further action, be amended and restated to read in its entirety as set forth on Annex II and, as so amended and restated, shall be the certificate of incorporation of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable Legal Requirements, subject to Section 6.5(a).

6

(b)    As of the Effective Time, the bylaws of the Surviving Corporation shall be amended and restated to conform to the bylaws of Purchaser as in effect immediately prior to the Effective Time, until thereafter changed or amended as provided therein or by applicable Legal Requirements, subject to Section 6.5(a), except that references to the name of Purchaser shall be replaced by references to the name of the Surviving Corporation.

(c)    As of the Effective Time, the directors and officers of the Surviving Corporation shall be the respective individuals who served as the directors and officers of Purchaser as of immediately prior to the Effective Time, until their respective successors are duly elected and qualified, or their earlier death, resignation or removal. Each director of the Company immediately prior to the Effective Time shall execute and deliver a letter effectuating his or her resignation as a member of the Board of Directors to be effective as of the Effective Time.

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

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

(ii)    any Shares held immediately prior to the Effective Time by Parent, Purchaser or any other direct or indirect wholly owned Subsidiary of Parent shall be cancelled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor;

(iii)    except as provided in clauses (i) and (ii) above and subject to Section 2.5(b), each Share outstanding immediately prior to the Effective Time, including any Shares subject to vesting or employment based forfeiture conditions (“Restricted Shares”) (other than any Dissenting Shares, which shall have only those rights set forth in Section 2.7) shall be converted into the right to receive the Offer Price (the “Merger Consideration”), in each case without any interest thereon, without regard to any vesting or employment based forfeiture conditions which were applicable to the corresponding Restricted Shares and subject to any withholding of Taxes in accordance with Section 2.6(e); and

(iv)    each share of the common stock, $0.01 par value per share, of Purchaser then outstanding shall be converted into one share of common stock of the Surviving Corporation. From and after the Effective Time, subject to this Section 2.5(a), all Shares shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and each applicable holder of such Shares shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration therefor upon the surrender of such shares of Company Common Stock in accordance with Section 2.6.

7

(b)    If, between the date of this Agreement and the Effective Time, the outstanding Shares are changed into a different number or class of shares by reason of any stock split, division or subdivision of shares, stock dividend, reverse stock split, consolidation of shares, reclassification, recapitalization or other similar transaction, then the Merger Consideration shall be appropriately adjusted.

(a)    Prior to the Offer Acceptance Time, Parent shall designate a bank or trust company reasonably acceptable to the Company to act as agent (the “Depository Agent”) for the holders of Shares to receive the aggregate Offer Price to which holders of such Shares shall become entitled pursuant to Section 1.1(b) and to act as agent (the “Paying Agent”) for the holders of Shares to receive the aggregate Merger Consideration to which holders of such Shares shall become entitled pursuant to Section 2.5. Promptly after (and in any event no later than the third business day after) the Offer Acceptance Time, Parent shall deposit, or shall cause to be deposited, with the Depository Agent cash sufficient to make the payment of the aggregate Offer Price payable pursuant to Section 1.1(h). On or prior to the Closing Date, Parent shall deposit, or shall cause to be deposited, with the Paying Agent cash sufficient to pay the aggregate Merger Consideration payable pursuant to Section 2.5 (together with the amount deposited pursuant the immediately preceding sentence, the “Payment Fund”). The Payment Fund shall not be used for any purpose other than to pay the aggregate Offer Price in the Offer and the aggregate Merger Consideration in the Merger. The Payment Fund shall be invested by the Paying Agent as directed by the Surviving Corporation; provided that such investments shall be (w) in obligations of or guaranteed by the United States of America, (x) in commercial paper obligations rated A-1 or P-1 or better by Moody’s Investors Service, Inc. or Standard & Poor’s Corporation, respectively, (y) in certificates of deposit, bank repurchase agreements or banker’s acceptances of commercial banks with capital exceeding one billion dollars, or (z) in money market funds having a rating in the highest investment category granted by a recognized credit rating agency at the time of acquisition or a combination of the foregoing and, in any such case, no such instrument shall have a maturity exceeding three months. To the extent Parent becomes aware that (i) there are any losses with respect to any such investments or (ii) the Payment Fund has diminished for any reason below the level required for the Paying Agent to make prompt cash payment pursuant to Section 1.1(h) and Section 2.5, Parent shall, or shall cause the Surviving Corporation to, promptly replace or restore the cash in the Payment Fund so as to ensure that the Payment Fund is, at all times during the duration of the Payment Fund, maintained at a level sufficient for the Paying Agent to make such payments pursuant to Section 1.1(h) and Section 2.5.

(b)    Promptly after the Effective Time (but in no event later than three business days thereafter), the Surviving Corporation shall cause to be delivered to each Person who was, at the Effective Time, a holder of record of (i) Shares represented by a certificate evidencing such Shares (the “Certificates”) or (ii) Book-Entry Shares, who, in each case was entitled to receive the Merger Consideration pursuant to Section 2.5, (A) a form of letter of transmittal, which shall be in reasonable and customary form and shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates (or affidavits of loss in lieu thereof in accordance with Section 2.6(f), if applicable)

8

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

(c)    At any time following 12 months after the Effective Time, Parent shall be entitled to require the Paying Agent to deliver to it any funds (with respect to the aggregate Merger Consideration to which holders of Shares shall become entitled pursuant to Section 2.5) which had been made available to the Paying Agent and not disbursed to holders of Certificates or Book-Entry Shares (including all interest and other income received by the Paying Agent in respect of all funds made available to it), and, thereafter, such holders shall be entitled to look to the Surviving Corporation (subject to abandoned property, escheat and other similar Legal Requirements) only as general creditors thereof with respect to the Merger Consideration that may be payable upon due surrender of the Certificates or Book-Entry Shares held by them, without any interest thereon. Notwithstanding the foregoing, neither the Surviving Corporation nor the Paying Agent shall be liable to any holder of Certificates or Book-Entry Shares for the Merger Consideration delivered in respect of such share to a public official pursuant to any abandoned property, escheat or other similar Legal Requirements. Any amounts remaining unclaimed by such holders at such time at which such amounts would otherwise escheat to or become property of any Governmental Body shall become, to the extent permitted by applicable Legal Requirements, the property of the Surviving Corporation or its designee, free and clear of all claims or interest of any Person previously entitled thereto.

9

(d)    At the close of business on the day of the Effective Time, the stock transfer books of the Company with respect to the Shares shall be closed and thereafter there shall be no further registration of transfers of Shares on the records of the Company. From and after the Effective Time, the holders of the Shares outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Shares except as otherwise provided herein or by applicable Legal Requirements. If, after the Effective Time, Certificates or Book-Entry Shares are presented to the Surviving Corporation for any reason, they shall be cancelled and exchanged as provided in this Agreement.

(e)    Each of the Company, the Surviving Corporation, Parent and Purchaser, and their Affiliates, the Paying Agent or the Depository Agent, as the case may be, shall be entitled to deduct and withhold, or cause to be deducted and withheld, from any amounts otherwise payable pursuant to this Agreement, such amounts as are required to be deducted and withheld under any Legal Requirement with respect to Taxes. Any amounts so deducted and withheld and paid over to the applicable Governmental Body in accordance with applicable Legal Requirements shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction or withholding was made.

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

2.7    Dissenters’ Rights. Notwithstanding anything in this Agreement to the contrary, Shares outstanding immediately prior to the Effective Time, and held by holders who are entitled to appraisal rights under Section 262 of the DGCL and have properly exercised and perfected their respective demands for appraisal of such Shares in the time and manner provided in Section 262 of the DGCL and, as of the Effective Time, have neither effectively withdrawn nor lost their rights to such appraisal and payment under the DGCL (the “Dissenting Shares”), shall not be converted into the right to receive Merger Consideration, but shall, by virtue of the Merger, be automatically cancelled and no longer outstanding, shall cease to exist and shall be entitled to only such consideration as shall be determined pursuant to Section 262 of the DGCL; provided that if any such holder shall have failed to perfect or shall have effectively withdrawn or lost such holder’s right to appraisal and payment under the DGCL, such holder’s Shares shall be deemed to have been converted as of the Effective Time into the right to receive the Merger Consideration (less any amounts entitled to be deducted or withheld pursuant to Section 2.6(e)), and such Shares shall not be deemed to be Dissenting Shares. The Company shall give prompt notice to Parent and Purchaser of any demands received by the Company for appraisal of any Dissenting Shares, withdrawals of such demands and any other instruments served pursuant to Section 262 of the DGCL, in each case prior to the Effective Time. Parent and Purchaser shall

10

have the right to direct and participate in all negotiations and proceedings with respect to such demands, and the Company shall not, without the prior written consent of Parent and Purchaser, settle or offer to settle, or make any payment with respect to, any such demands, approve any withdrawal of any such demands or agree or commit to do any of the foregoing.

(a)    At the Effective Time, each Company Option that is then outstanding and unexercised, whether or not vested and which has a per share exercise price that is less than the Merger Consideration, shall be cancelled and converted into the right to receive a cash payment equal to (i) the excess of (A) the Merger Consideration over (B) the exercise price payable per Share under such Company Option, multiplied by (ii) the total number of Shares subject to such Company Option immediately prior to the Effective Time.

(b)    As soon as reasonably practicable after the Effective Time (but in no event later than the second payroll date following the Effective Time), Parent shall cause the Surviving Corporation to, and the Surviving Corporation shall, pay the consideration payable pursuant to Section 2.8(a), net of any applicable withholding Taxes, to the holders of Company Options through, to the extent applicable, the Surviving Corporation’s payroll.

(c)    Prior to the Offer Acceptance Time, the Company shall take all actions that are necessary (under the Company Equity Plans and award agreements pursuant to which Company Options are outstanding or otherwise) to effect the transactions described in this Section 2.8.

2.9    Further Action. The Parties agree to take all necessary action to cause the Merger to become effective in accordance with this Section 2 as soon as practicable following the consummation of the Offer without a meeting of the Company’s stockholders, as provided in Section 251(h) of the DGCL. If, at any time after the Effective Time, any further action is reasonably determined by Parent to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full right, title and possession of and to all rights and property of Purchaser and the Company, the officers and directors of the Surviving Corporation and Parent shall be fully authorized (in the name of Purchaser, in the name of the Company and otherwise) to take such action.

This Agreement has been duly executed and delivered by the Company, and assuming due authorization, execution and delivery by Parent and Purchaser, this Agreement constitutes the legal, valid and binding obligation of the Company and is enforceable against the Company in accordance with its terms, except as such enforcement may be subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and other similar laws of general applicability relating to or affecting creditors’ rights, and by general equitable principles. If the Merger is consummated in accordance with Section 251(h) of the DGCL as contemplated hereby, no vote of the Company’s stockholders or any holder of Shares is necessary to authorize or adopt this Agreement or to consummate the Transactions, assuming the accuracy of the representations set forth in Section 4.8.

(a)    Since January 1, 2018, the Company has filed or furnished on a timely basis all reports, schedules, forms, statements and other documents (including exhibits and all other information incorporated therein) required to be filed or furnished by the Company with the SEC (as supplemented, modified or amended since the time of filing, the “Company SEC Documents”). As of their respective dates, or, if amended prior to the date of this Agreement, as of the date of (and giving effect to) the last such amendment (and, in the case of registration statements and proxy statements, on the date of effectiveness and the dates of the relevant meetings, respectively), the Company SEC Documents complied in all material respects with the requirements of the Securities Act, the Exchange Act or the Sarbanes-Oxley Act of 2001, as amended (the “Sarbanes-Oxley Act”), as the case may be, and the rules and regulations of the SEC promulgated thereunder applicable to those Company SEC Documents, and, except to the extent that information contained in such Company SEC Document has been revised, amended, modified or superseded (prior to the date of this Agreement) by a later filed Company SEC Document, none of the Company SEC Documents when filed or furnished contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

14

(c)    The Company maintains a system of “internal control over financial reporting” (as defined in Rule 13a-15 under the Exchange Act), which is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP, and includes those policies and procedures that: (i) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and that receipts and expenditures are being made only in accordance with authorizations of management and the Board of Directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the assets of the Company that could have a material effect on its financial statements. The Company’s management has completed an assessment of the effectiveness of the Company’s system of internal control over financial reporting in compliance with the requirements of Section 404 of the Sarbanes-Oxley Act for the fiscal year ended December 31, 2019, and, except as set forth in the Company SEC Documents filed prior to the date of this Agreement, that assessment concluded that those controls were effective. To the knowledge of the Company, since January 1, 2020, neither the Company nor the Company’s independent registered accountant has identified or been made aware of: (1) any significant deficiency or material weakness in the design or operation of the internal control over financial reporting utilized by the Company, which is reasonably likely to adversely affect the Company’s ability to record, process, summarize and report financial information; or (2) any fraud, whether or not material, that involves the management or other employees of the Company who have a significant role in the Company’s internal control over financial reporting.

(d)    The Company maintains disclosure controls and procedures as defined in and required by Rule 13a-15 or 15d-15 under the Exchange Act that are reasonably designed to ensure that all information required to be disclosed in the Company’s reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and that all such information is accumulated and communicated to the Company’s management as appropriate to allow timely decisions regarding required disclosure and to enable the principal executive officer of the Company and the principal financial officer of the Company to make the certifications required under the Exchange Act with respect to such reports. The Company is in compliance in all material respects with all current listing and corporate governance requirements of NASDAQ.

(e)    The Company is not a party to, nor does it have any obligation or other commitment to become a party to, “off-balance sheet arrangements” (as defined in Item 303(a) of Regulation S-K under the Exchange Act) where the result, purpose or intended effect of such Contract is to avoid disclosure of any material transaction involving, or material liabilities of, the Company in the Company SEC Documents.

(f)    As of the date of this Agreement, there are no outstanding or unresolved comments in comment letters received from the SEC with respect to the Company SEC Documents. To the knowledge of the Company, none of the Company SEC Documents is the subject of ongoing SEC review and there are no inquiries or investigations by the SEC or any internal investigations pending or threatened in writing, in each case regarding any accounting practices of the Company, except as has not had, and would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

15

(g)    Each document required to be filed by the Company with the SEC in connection with the Offer, including the Schedule 14D-9 (the “Company Disclosure Documents”), and any amendments or supplements thereto, when filed, distributed or otherwise disseminated to the Company’s stockholders, as applicable, will comply as to form in all material respects with the applicable requirements of the Exchange Act. The Company Disclosure Documents, at the time of the filing of such Company Disclosure Documents or any supplement or amendment thereto with the SEC and at the time such Company Disclosure Documents or any supplements or amendments thereto are first distributed or otherwise disseminated to the Company’s stockholders, will 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 light of the circumstances under which they were made, not misleading.

(i)    The information with respect to the Company that the Company furnishes to Parent or Purchaser specifically for use in the Offer Documents, at the time of the filing of and at the time of any distribution or dissemination of the Offer Documents, will 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 light of the circumstances under which they were made, not misleading.

(ii)    Notwithstanding the foregoing, the Company makes no representation with respect to statements made or incorporated by reference therein based on information supplied by or on behalf of Parent or Purchaser for inclusion or incorporation by reference in the Company Disclosure Documents.

16

(a)    The Company does not own any real property.

No vote of Parent’s or Purchaser’s stockholders is necessary to approve this Agreement or any of the Transactions (except in the case of Purchaser as has been obtained prior to the execution hereof).

4.5    Disclosure. None of the Offer Documents will contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

34

normal business hours of the Company to the Company’s Representatives, designated personnel and assets and to all existing books, records, documents and information relating to the Company, and promptly provide Parent and Parent’s Representatives with all reasonably requested information regarding the business of the Company and such additional financial, operating and other data and information regarding the Company, as Parent may reasonably request, in each case for any reasonable business purpose related to the consummation of the Transactions; provided, however, that any such access shall be conducted at Parent’s expense, at a reasonable time, 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. Any such access shall be subject to the Company’s reasonable security measures and insurance requirements and shall not include invasive testing. Nothing herein shall 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 permit such inspection of or to disclose such information on a basis that does not waive such privilege with respect thereto), (ii) contravene any applicable Legal Requirement or Contract (so long as the Company has reasonably cooperated with Parent to permit disclosure to the extent permitted by Legal Requirements or the contractual counterparty); provided, however, in the case of clause (ii), that the Parties shall cooperate in seeking to find a way to allow disclosure of such information to the extent doing so could reasonably (in the good faith belief of the Company (after consultation with outside counsel)) be managed through the use of customary “clean room” arrangements pursuant to which non-employee Representatives of Parent could be provided access to such information. With respect to the information disclosed pursuant to this Section 5.1, Parent shall comply with, and shall instruct Parent’s Representatives to comply with, all of its obligations under the Mutual Confidential Disclosure Agreement, effective as of January 7, 2020, between the Company and Parent (the “Confidentiality Agreement”).

(ii) (A) The Company shall give prompt notice to Parent of any change, circumstance, condition, development, effect, event, occurrence or state of facts that has had or would reasonably be expected to have a Material Adverse Effect, or would reasonably be expected to make the satisfaction of any of the Offer Conditions impossible or unlikely, and (B) Parent shall give prompt notice to the Company of any change, circumstance, condition, development, effect, event, occurrence or state of facts that has had or would reasonably be expected to have a Parent Material Adverse Effect, or would reasonably be expected to make the satisfaction of any of the Offer Conditions impossible or unlikely.

35

(iii) For the avoidance of doubt, the delivery of any notice pursuant to this Section 5.1(b) shall not cure any breach of any representation or warranty requiring disclosure of such matter prior to the date of this Agreement or otherwise limit or affect the remedies available hereunder to any Party. The failure to deliver any such notice shall not affect any Offer Condition or any of the conditions set forth in Section 7 or give rise to any right to terminate under Section 8.

5.2    Operation of the Company’s Business.

As promptly as reasonably practicable (and in any event within two business days) following the date hereof, the Company shall discontinue electronic or physical data room access granted, and request the prompt return or destruction (to the extent provided for by the applicable confidentiality agreement) of all information or documents previously furnished to any Person (other than Parent, its Affiliates and their respective Representatives) that has made, has indicated an intention to make an Acquisition Proposal and all material incorporating such information created by any such Person.

(b)    If at any time on or after the date of this Agreement and prior to the Offer Acceptance Time the Company or any of its Representatives receives a bona fide written Acquisition Proposal from any Person or group of Persons, which Acquisition Proposal was made on or after the date of this Agreement and did not result from a material breach of this Section 5.3, and the Board of Directors determines in good faith, after consultation with its financial advisor and outside legal counsel, that such Acquisition Proposal constitutes or would reasonably be expected to result in a Superior Offer and that the failure to take such action described in clauses (x) and (y) below would be inconsistent with its fiduciary duties under applicable Legal Requirements, then, notwithstanding anything in Section 5.3(a) to the contrary, the Company and its Representatives may (x) furnish, pursuant to an Acceptable Confidentiality Agreement, information (including non-public information) with respect to the Company to the Person or group of Persons who has made such Acquisition Proposal, provided that the Company shall as promptly as practicable (and in any event within 36 hours) provide to Parent any information concerning the Company that is provided to any Person to the extent access to such information was not previously provided to Parent or its Representatives; and (y) engage in or otherwise participate in discussions or negotiations with the Person or group of Persons making such Acquisition Proposal; provided, in the case of clauses (x) and (y), that at or prior to the first time that the Company furnishes any information to or participates in any discussions or negotiations with any Person on or after the date of this Agreement, the Company shall provide written notice to Parent of such determination in good faith of the Board of Directors as provided for above.

(c)    During the Pre-Closing Period, the Company shall (i) promptly (and in any event within 36 hours) notify Parent orally and in writing if any inquiries, proposals or offers with respect to, or that would reasonably be expected to lead to, an Acquisition Proposal are received by the Company or any of its Representatives and provide to Parent a copy of any written Acquisition Proposal (including any proposed term sheet, letter of intent, acquisition agreement or other agreement or other supporting materials with respect thereto) and a summary of any material unwritten terms and conditions thereof (and indicate the identity of such Person), and (ii) keep Parent reasonably informed of any material developments, discussions or negotiations regarding any Acquisition Proposal on a prompt basis (and in any event within 36 hours of such material development, discussion or negotiation).

(d)    Nothing in this Section 5.3 or elsewhere in this Agreement shall prohibit the Company from disclosing to the stockholders of the Company any “stop, look and listen” communication pursuant to Rule 14d-9(f) promulgated under the Exchange Act or from taking and disclosing such other position or disclosure as is required under Rule 14e-2(a), Rule 14d-9 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act or from taking any action

40

necessary to comply with applicable Legal Requirements; provided, however, that, the Board of Directors shall not effect a Company Adverse Change Recommendation except in accordance with Section 6.1(b).

(e)    The Company agrees that in the event any Representative of the Company acting on behalf of the Company takes any action that, if taken by the Company, would constitute a breach of this Section 5.3, the Company shall be deemed to be in breach of this Section 5.3.

SECTION 6

ADDITIONAL COVENANTS OF THE PARTIES

(a)    Subject to Section 6.1(b), the Company hereby consents to the inclusion of a description of the Company Board Recommendation in the Offer Documents. During the Pre-Closing Period, subject to Section 6.1(b), neither the Board of Directors nor any committee thereof shall (i)(A) withdraw or withhold (or modify or qualify in a manner adverse to Parent or Purchaser), or publicly propose to withdraw or withhold (or modify or qualify in a manner adverse to Parent or Purchaser), the Company Board Recommendation, (B) adopt, approve, recommend or declare advisable, or publicly propose to adopt, approve, recommend or declare advisable, any Acquisition Proposal, (C) after public announcement of an Acquisition Proposal (other than a tender offer or exchange offer), fail to publicly affirm the Company Board Recommendation within three business days after a written request by Parent to do so (or, if earlier, by the close of business on the business day immediately preceding the scheduled date of the Offer Acceptance Time), provided, that Parent may only make such request once with respect to any Acquisition Proposal (provided, that each time a Determination Notice is given Parent shall, subject to the following provision, be entitled to make a new such request); and provided, further, that the Company shall not be required to provide any such affirmation during the two or three business day periods, as applicable, following the giving of a Determination Notice, (D) following the commencement of a tender offer or exchange offer relating to the Shares by a Person unaffiliated with Parent, fail to publicly affirm the Company Board Recommendation and recommend that the Company’s stockholders reject such tender offer or exchange offer within 10 business days after the commencement of such tender offer or exchange offer pursuant to Rule 14d-9(f) promulgated under the Exchange Act (or, if earlier, by the close of business on the business day immediately preceding the scheduled date of the Offer Acceptance Time) or (E) fail to include the Company Board Recommendation in the Schedule 14D-9 when filed with the SEC or disseminated to the Company’s stockholders (any action described in this clause (i) being referred to as a “Company Adverse Change Recommendation”) or (ii) approve, recommend or declare advisable, or propose to approve, recommend or declare advisable, or cause or allow the Company to execute or enter into any Contract, letter of intent, memorandum of understanding, agreement in principle or term sheet with respect to, or that is intended to or would reasonably be expected to lead to, any Acquisition Proposal, or requiring, or reasonably expected to cause, the Company to abandon, terminate, delay or fail to consummate, or that would otherwise materially impede, interfere with or be inconsistent with, the Transactions (other than an Acceptable Confidentiality Agreement).

41

(b)    Notwithstanding anything to the contrary contained in this Agreement, at any time prior to the Offer Acceptance Time, and subject to compliance with the other provisions of this Section 6.1:

(i)    if the Company has received a bona fide written Acquisition Proposal from any Person that has not been withdrawn and after consultation with outside legal counsel and its financial advisor, the Board of Directors shall have determined, in good faith, that such Acquisition Proposal constitutes a Superior Offer, (x) the Board of Directors may make a Company Adverse Change Recommendation, or (y) provided that the Company is not in breach of Section 5.3 in any material respect and in a manner that led to such Acquisition Proposal and subject to the other provisions of Section 8.1(e), the Company may terminate this Agreement pursuant to Section 8.1(e) to enter into a Specified Agreement with respect to such Superior Offer, in each case, if and only if: (A) the Board of Directors determines in good faith, after consultation with the Company’s outside legal counsel and its financial advisor, that the failure to do so would be inconsistent with the fiduciary duties of the Board of Directors under applicable Legal Requirements; (B) the Company shall have given Parent prior written notice of its intention to consider making a Company Adverse Change Recommendation or terminating this Agreement pursuant to Section 8.1(e) at least three business days prior to making any such Company Adverse Change Recommendation or termination (a “Determination Notice”) (which notice shall not constitute a Company Adverse Change Recommendation or termination) and, if requested in writing by Parent during such three business day period, shall have negotiated, and caused its Representatives to negotiate, in good faith with respect to any revisions to the terms of this Agreement or another proposal to the extent proposed by Parent so that such Acquisition Proposal would cease to constitute a Superior Offer; and (C) (1) the Company shall have provided to Parent information with respect to such Acquisition Proposal in accordance with Section 5.3(c), as well as a copy of any acquisition agreement with respect to such Acquisition Proposal and a copy of any financing commitments relating thereto (or, if not provided in writing to the Company, a written summary of the material terms thereof), (2) the Company shall have given Parent the three business day period after the Determination Notice to propose revisions to the terms of this Agreement or make another proposal so that such Acquisition Proposal would cease to constitute a Superior Offer, and (3) after giving effect to the proposals made by Parent during such period, if any, after consultation with outside legal counsel and its financial advisor, the Board of Directors shall have determined, in good faith, that such Acquisition Proposal constitutes a Superior Offer and that the failure to make the Company Adverse Change Recommendation or terminate this Agreement pursuant to Section 8.1(e) would be inconsistent with the fiduciary duties of the Board of Directors under applicable Legal Requirements. Issuance of any “stop, look and listen” communication by or on behalf of the Company pursuant to Rule 14d-9(f) promulgated under the Exchange Act, taking and disclosing a position or otherwise making any disclosure as is required under Rule 14e-2(a), Rule 14d-9 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act or otherwise complying with applicable Legal Requirements shall not, in and of itself, be considered a Company Adverse Change Recommendation and shall not require the giving of a Determination Notice or compliance with the procedures set forth in this Section 6.1. The provisions of this Section 6.1(b)(i) shall also

42

apply to any change to any of the financial terms (including the form, amount and timing of payment of consideration) or other material amendment to any Acquisition Proposal and require a new Determination Notice (provided that for the purposes of such subsequent Determination Notice, all references to “three business days” shall be deemed to be “two business days”); and

(ii)    other than in connection with a Superior Offer (which shall be subject to Section 6.1(b)(i)), the Board of Directors may make a Company Adverse Change Recommendation in response to an Intervening Event if: (A) the Board of Directors determines in good faith, after consultation with the Company’s outside legal counsel and its financial advisor, that the failure to do so would be inconsistent with the fiduciary duties of the Board of Directors under applicable Legal Requirements; (B) the Company shall have given Parent a Determination Notice at least three business days prior to making any such Company Adverse Change Recommendation and, if desired by Parent, during such three business day period shall have negotiated, and caused its Representatives to negotiate, in good faith with respect to any revisions to the terms of this Agreement or another proposal to the extent proposed by Parent so that a Company Adverse Change Recommendation would no longer be necessary; and (C) (1) the Company shall have specified in reasonable detail the facts and circumstances that render a Company Adverse Change Recommendation necessary, (2) the Company shall have given Parent the three business day period after the Determination Notice to propose revisions to the terms of this Agreement or make another proposal so that a Company Adverse Change Recommendation would no longer be necessary, and (3) after giving effect to the proposals made by Parent during such period, if any, after consultation with outside legal counsel, the Board of Directors shall have determined, in good faith, that the failure to make the Company Adverse Change Recommendation would be inconsistent with the fiduciary duties of the Board of Directors under applicable Legal Requirements. The provisions of this Section 6.1(b)(ii) shall also apply to any material change to the facts and circumstances specified by the Company pursuant to clause (C)(1) above and require a new Determination Notice (provided that for the purposes of such subsequent Determination Notice, all references to “three business days” shall be deemed to be “two business days”).

(a)    The Parties agree to use their reasonable best efforts to take promptly any and all steps necessary to avoid or eliminate each and every impediment under the Antitrust Laws, that may be asserted by any Governmental Body, so as to enable the Closing to occur as promptly as practicable, but in no case later than the End Date, including providing as promptly as reasonably practicable and advisable all non-legally privileged information reasonably required by any Governmental Body pursuant to its evaluation of the Transactions under the HSR Act. Subject to the terms of this Section 6.2, the Parties shall use their reasonable best efforts to obtain from any Governmental Body all consents, approvals authorizations or orders required to be obtained under the Antitrust Laws or to avoid the entry or enactment of any injunction or other order or decree relating to any Antitrust Law that would delay, restrain, prevent, enjoin or otherwise prohibit consummation of the Transactions. Notwithstanding anything to the contrary in this Agreement, Parent and its Affiliates shall not be required to, and without the prior written consent of Parent the Company shall not, sell, license, divest or dispose of or hold separate (through the establishment of a trust or otherwise) or agree to any other

43

structural, behavioral or conduct remedy, before or after the Offer Acceptance Time or the Effective Time, any entities, businesses, divisions, operations, products or product lines, assets, Intellectual Property Rights or businesses of Parent, the Company (or any of their respective Subsidiaries or other Affiliates) or agree to any restriction on the conduct of such businesses which (A) would materially and adversely affect the business of Parent and its Subsidiaries, taken as a whole, or (B) would require the sale, license, divestiture, disposal, or holding separate of, or any other structural, behavioral or conduct remedy involving the Product Candidates. Nothing in this Section 6.2 shall require the Parent or the Company to take or agree to take any action unless the effectiveness of such action is conditioned upon Closing. Notwithstanding the foregoing and any other provision of this Agreement to the contrary, in no event shall Parent, Purchaser, the Company or any of their respective Subsidiaries be obligated to litigate or participate in the litigation of any action, whether judicial or administrative, brought by any Governmental Body challenging or seeking to restrain, prohibit or place conditions on the consummation of the Transactions.

(b)    Subject to the terms and conditions of this Agreement, each of the Parties shall (and shall cause their respective Affiliates, if applicable, to): (i) as promptly as reasonably practicable (but no later than 10 business days after the date of this Agreement), make an appropriate filing of all Notification and Report forms as required by the HSR Act, with respect to the Transactions and (ii) cooperate with each other in determining whether, and promptly preparing and making, any other filings, notifications or other consents are required to be made with, or obtained from, any other Governmental Bodies in connection with the Transactions.

(c)    Without limiting the generality of anything contained in this Section 6.2, during the Pre-Closing Period, each Party shall (i) give the other Parties prompt notice of the making or commencement of any request, inquiry, investigation, action or Legal Proceeding brought by a Governmental Body or brought by a third party before any Governmental Body, in each case, with respect to the Transactions under the Antitrust Laws, (ii) keep the other Parties reasonably informed as to the status of any such request, inquiry, investigation, action or Legal Proceeding, (iii) promptly inform the other Parties of, and wherever practicable give the other party reasonable advance notice of, and the opportunity to participate in, any communication to or from the FTC, DOJ or any other Governmental Body in connection with any such request, inquiry, investigation, action or Legal Proceeding, (iv) promptly furnish to the other Party, subject to an appropriate confidentiality agreement to limit disclosure to counsel and outside consultants, with copies of documents provided to or received from any Governmental Body in connection with any such request, inquiry, investigation, action or Legal Proceeding (except that documents, including “4(c) and 4(d) documents” as that term is used under the HSR Act, that contain valuation information can be redacted), (v) subject to an appropriate confidentiality agreement to limit disclosure to counsel and outside consultants, and to the extent reasonably practicable, consult and cooperate with the other Parties and consider in good faith the views of the other Parties in connection with any written analysis, appearance, presentation, memorandum, brief, argument, opinion or proposal made or submitted in connection with any such request, inquiry, investigation, action or Legal Proceeding, and (vi) except as may be prohibited by any Governmental Body or by any Legal Requirement, in connection with any such request, inquiry, investigation, action or Legal Proceeding in respect of the Transactions, give the other Party reasonable prior notice and permit authorized Representatives of the other

44

Party to be present at each meeting or conference, including by telephone, relating to such request, inquiry, investigation, action or Legal Proceeding and to have access to and be consulted in advance in connection with any argument, opinion or proposal made or submitted to any Governmental Body in connection with such request, inquiry, investigation, action or Legal Proceeding.

(d)    During the Pre-Closing Period, the Company shall to the extent permissible under applicable Legal Requirements and reasonably practicable and where doing so would not reasonably be expected to impair or adversely affect the Company, any of its plans with respect to the Product Candidates or its ability to interact with any Governmental Body consistent with companies at similar stages of development in the pharmaceutical industry (in each case as determined in good faith by the Company) (i) offer Parent the opportunity to consult with the Company prior to any proposed material meeting or other material communication with the FDA, EMA, the Centers for Medicare & Medicaid Services (“CMS”) or any other Specified Governmental Body relating to any Product Candidate or material Governmental Authorization (it being understood that in no event shall the Company be required to delay or modify any of its actions as a result of this Section 6.2(d)), (ii) promptly inform Parent of, and provide Parent with a reasonable opportunity to review, in advance, any material filing proposed to be made by or on behalf of the Company, and any material correspondence or other material communication proposed to be submitted or otherwise transmitted to the FDA, EMA, CMS or any other Specified Governmental Body by or on behalf of the Company, in each case relating to any Product Candidate or material Governmental Authorization (it being understood that in no event shall the Company be required to delay any such filings, correspondence or communication), (iii) keep Parent reasonably informed of any material communication (written or oral) with or from the FDA, EMA, CMS or any other Specified Governmental Body or relating to any Product Candidate or Governmental Authorization and (iv) promptly inform Parent and provide Parent with a reasonable opportunity (but no more than two business days, to the extent practicable) to comment, in each case, prior to making any material change to any study protocol, adding any new trial, making any material change to a manufacturing plan or process, making any material change to a development timeline or initiating, or making any material change to, commercialization and reimbursement activities or materials (including promotional and marketing activities and materials) relating to any Product Candidate. The Company shall promptly notify Parent of any significant data relating to any Product Candidate, including information related to any significant adverse events with respect to any Product Candidate, in each case which it discovers after the date hereof.

(e)    Neither Party shall enter into any agreement, transaction, or any agreement to effect any transaction (including any merger or acquisition) that would reasonably be expected to make it materially more difficult, or to materially increase the time required, to (i) obtain the expiration or termination of the waiting period under the HSR Act, (ii) avoid the entry of, the commencement of litigation seeking the entry of, or to effect the dissolution of, any injunction, temporary restraining order or other order that would materially delay or prevent the consummation of the transactions contemplated hereby, or (iii) obtain all authorizations, consents, orders and approvals of Governmental Bodies necessary for the consummation of the transactions contemplated hereby.

45

(a)    For a period commencing at the Effective Time and ending on the one year anniversary of the Effective Time, Parent shall provide, or cause to be provided, to those employees of the Company who are employed by the Company as of immediately prior to the Effective Time and who continue to be actively employed by the Surviving Corporation (or any Affiliate thereof) during such period (the “Continuing Employees”) with (i) the base salary or wage rate and annual cash bonus opportunities (excluding equity-based compensation opportunities) that are, in each case, no less than those provided by the Company immediately prior to the Offer Acceptance Time; (ii) retirement and welfare benefits that are no less favorable in the aggregate than those provided by the Company immediately prior to the Offer Acceptance Time; and (iii) severance benefits no less favorable than those provided to by the Company immediately prior to the Offer Acceptance Time.

(b)    Parent agrees that all Continuing Employees shall be eligible to continue to participate in the Surviving Corporation’s health and welfare benefit plans (to the same extent such Continuing Employees were eligible to participate under the health and welfare benefit plans of the Company immediately prior to the Effective Time); provided, however, that (i) nothing in this Section 6.3 or elsewhere in this Agreement shall limit the right of Parent or the Surviving Corporation to amend or terminate any such health or welfare benefit plan at any time, subject to the requirements set forth in Section 6.3(a), and (ii) if Parent or the Surviving Corporation terminates any such health or welfare benefit plan (upon expiration of any appropriate transition period), then the Continuing Employees shall be eligible to participate in the Surviving Corporation’s (or an Affiliate’s) health and welfare benefit plans to the extent that coverage under such plans is replacing comparable coverage under an Employee Plan in which such Continuing Employee participated immediately before the Effective Time. To the extent that service is relevant under any benefit plan of Parent or an Affiliate and/or the Surviving Corporation, then Parent shall ensure that such benefit plan shall, for all purposes, credit Continuing Employees for service prior to the Effective Time with the Company and its Affiliates or their respective predecessors; provided, that, if such benefit plan replaces a benefit plan of the Company that recognized service for the same purpose, such service will be recognized to the same extent that such service was recognized prior to the Effective Time under the corresponding benefit plan of the Company. Nothing in this Section 6.3 or elsewhere in this Agreement shall be construed to create a right in any Person to employment with Parent, the Surviving Corporation or any other Affiliate of the Surviving Corporation and the employment of each Continuing Employee shall be “at will” employment.

(c)    To the extent permitted under applicable Legal Requirements, with respect to any employee benefit plans maintained for the benefit of the Continuing Employees following the Effective Time, Parent shall, and shall cause the Surviving Corporation, any of its Affiliates, and any successor thereto, to (i) cause there to be waived any eligibility requirements or pre-existing condition limitations or waiting period requirements to the same extent waived or satisfied under comparable plans of the Company or its Subsidiaries, and (ii) give effect, in determining any deductible, co-insurance and maximum out-of-pocket limitations, amounts paid by such employees during the calendar year in which the Effective Time occurs under similar plans maintained by the Company.

46

(d)    The provisions of this Section 6.3 are solely for the benefit of the Parties, and no provision of this Section 6.3 is intended to, or shall, constitute the establishment or adoption of or an amendment to any employee benefit plan for purposes of ERISA or otherwise, and no current or former employee or any other individual associated therewith shall be regarded for any purpose as a third party beneficiary of this Agreement or have the right to enforce the provisions hereof.

6.4    ESPP. As soon as reasonably practicable after the date of this Agreement, the Company shall take all necessary actions under the Company ESPP to provide that (a) the “Offering” (as defined in the Company ESPP) in effect as of the date of this Agreement shall be the final Offering (such period, the “Final Offering”) and no further Offering shall commence pursuant to the Company ESPP after the date of this Agreement, and (b) each individual participating in the Final Offering on the date of this Agreement shall not be permitted to (i) increase his or her payroll contribution rate pursuant to the Company ESPP from the rate in effect when the Final Offering commenced or (ii) make separate non-payroll contributions to the Company ESPP on or following the date of this Agreement, except as may be required by applicable Legal Requirement. Prior to the Offer Acceptance Time, the Company shall take all action that may be necessary to, effective upon the Offer Acceptance Time, (A) cause the Final Offering, to the extent that it would otherwise be ongoing at the Offer Acceptance Time, to be terminated no later than five business days prior to the date on which the Offer Acceptance Time occurs; (B) make any pro rata adjustments that may be necessary to reflect the Final Offering, but otherwise treat the Final Offering as a fully effective and completed Offering for all purposes pursuant to the Company ESPP; and (C) cause the exercise (as of no later than five business days prior to the date on which the Offer Acceptance Time occurs) of each outstanding purchase right pursuant to the Company ESPP. On such exercise date, the Company shall apply the funds credited as of such date pursuant to the Company ESPP within each participant’s payroll withholding account to the purchase of Shares in accordance with the terms of the Company ESPP, and each Share shall be an outstanding Share and entitled to the Merger Consideration. The Company shall adopt such resolutions as are necessary to terminate the Company ESPP effective as of immediately prior to, and conditional upon the occurrence of, the Offer Acceptance Time.

(a)    For a period of six years from the Effective Time, Parent agrees that all rights to indemnification, advancement of expenses and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time (whether asserted or claimed prior to, at or after the Effective Time) now existing in favor of the current or former directors or officers of the Company under the certificate of incorporation and bylaws of the Company and any indemnification or other similar agreements of the Company set forth on Section 6.5(a) of the Company Disclosure Schedule, in each case as in effect on the date of this Agreement, shall continue in full force and effect in accordance with their terms and shall not be amended, repealed or otherwise modified in any manner that would adversely affect the rights thereunder of any Indemnified Person (as defined below), and Parent shall cause the Company to perform its obligations thereunder. Without limiting the foregoing, during the period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time, Parent shall cause the

47

Surviving Corporation and its Subsidiaries to, and the Surviving Corporation agrees that it will, indemnify and hold harmless each individual who is as of the date of this Agreement, or who becomes prior to the Effective Time, a director or officer of the Company or who is as of the date of this Agreement, or who thereafter commences prior to the Effective Time, serving at the request of the Company as a director or officer of another Person (the “Indemnified Persons”), against all claims, losses, liabilities, damages, judgments, inquiries, fines and reasonable fees, costs and expenses, including attorneys’ fees and disbursements, incurred in connection with any claim, action, suit or proceeding, whether civil, criminal, administrative or investigative (including with respect to matters existing or occurring at or prior to the Effective Time, including this Agreement and the transactions and actions contemplated hereby), arising out of or pertaining to the fact that the Indemnified Person is or was a director or officer of the Company or is or was serving at the request of the Company as a director or officer of another Person, whether asserted or claimed prior to, at or after the Effective Time, to the fullest extent permitted under applicable Legal Requirements. In the event of any such claim, action, suit or proceeding, (x) each Indemnified Person will be entitled to advancement of expenses incurred in the defense of any such claim, action, suit or proceeding from Parent, the Surviving Corporation or its Subsidiaries, as applicable, in accordance with the organizational documents and any indemnification or other similar agreements of the Surviving Corporation or its Subsidiaries, as applicable, as in effect on the date of this Agreement; provided that any Indemnified Person to whom expenses are advanced provides an undertaking, if and only to the extent required by the DGCL or the Surviving Corporation’s or any of its Subsidiaries’ certificate of incorporation or bylaws (or comparable organizational documents) or any such indemnification or other similar agreements, as applicable; to repay such advances if it is ultimately determined by final adjudication that such Indemnified Person is not entitled to indemnification and (y) Parent, the Surviving Corporation and its Subsidiaries, as applicable, shall reasonably cooperate in the defense of any such matter.

(b)    For a period of six years from and after the Effective Time, Parent and the Surviving Corporation shall either cause to be maintained in effect the current policies of directors’ and officers’ liability insurance maintained by the Company or provide substitute policies for the Company and its current and former directors and officers who are currently covered by the directors’ and officers’ insurance coverage currently maintained by the Company, in either case, of not less than the existing coverage and having other terms not less favorable to the insured persons than the directors’ and officers’ liability insurance coverage currently maintained by the Company with respect to claims arising from facts or events that occurred at or before the Effective Time (with insurance carriers having at least an “A” rating by A.M. Best with respect to directors’ and officers’ liability insurance), except that in no event shall Parent or the Surviving Corporation be required to pay with respect to such insurance policies an annual premium greater than 300% of the aggregate annual premium most recently paid by the Company prior to the date of this Agreement (the “Maximum Amount”), and if the Surviving Corporation is unable to obtain the insurance required by this Section 6.5(b) it shall obtain as much comparable insurance as possible for the years within such six year period for a premium equal to the Maximum Amount. In lieu of such insurance, prior to the Closing Date the Company may purchase a “tail” directors’ and officers’ liability insurance policy for the Company and its current and former directors and officers who are currently covered by the directors’ and

48

officers’ liability insurance coverage currently maintained by the Company, such tail to provide coverage in an amount not less than the existing coverage and to have other terms not less favorable to the insured persons than the directors’ and officers’ liability insurance coverage currently maintained by the Company with respect to claims arising from facts or events that occurred at or before the Effective Time; provided that in no event shall the cost of any such tail policy exceed the Maximum Amount. Parent and the Surviving Corporation shall maintain such policies in full force and effect, and continue to honor the obligations thereunder.

(c)    In the event that the Company or any of its successors or assigns (i) consolidates with or merges into any other Person and is not 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, the Company, as applicable, shall cause proper provision to be made so that the successors and assigns of the Company assume the obligations set forth in this Section 6.5.

(d)    The provisions of this Section 6.5 (i) shall survive the acceptance of Shares for payment pursuant to the Offer and the consummation of the Merger and (ii) are intended to be for the benefit of, and will be enforceable by, each indemnified or insured party (including the Indemnified Persons), his or her heirs, successors, assigns and representatives, and (iii) are in addition to, and not in substitution for, any other rights to indemnification, advancement of expenses, exculpation or contribution that any such Person may have by contract or otherwise. Unless required by applicable Legal Requirement, this Section 6.5 may not be amended, altered or repealed after the Offer Acceptance Time in such a manner as to adversely affect the rights of any Indemnified Person or any of their successors, assigns or heirs without the prior written consent of the affected Indemnified Person.

6.6    Stockholder Litigation. In the event that any litigation related to this Agreement, the Offer, the Merger or the other Transactions is brought by any stockholder or other holder of Company securities (whether directly or on behalf of the Company or otherwise) against the Company and/or its directors or officers, the Company shall promptly notify Parent and shall keep Parent reasonably and promptly informed with respect to the status thereof. The Company shall give Parent the (a) opportunity to participate in the defense of any such litigation, (b) right to review and comment on all material filings or responses to be made by the Company in connection with such litigation (and shall give due consideration to Parent’s comments and other advice with respect to such litigation) and (c) right to consult on any settlement with respect to such litigation, and no such settlement shall be agreed to without Parent’s prior written consent, such consent not to be unreasonably withheld; provided, however, that in no event shall Parent be required to consent (such consent not to be unreasonably withheld, conditioned or delayed) to any such settlement that does not provide for the unconditional release of Parent, its Affiliates and Representatives and all Persons entitled to indemnification by Parent or the Company, in each case from any liability in connection with such litigation; provided further, that the Company shall otherwise control the defense and/or settlement and the disclosure of information in connection therewith shall be subject to the provisions of Section 5.1, including regarding attorney-client privilege or other applicable legal privilege.

49

6.7    Additional Agreements. Subject to the terms and conditions of this Agreement, including Section 6.2(a), Parent and the Company shall use reasonable best efforts to take, or cause to be taken, all actions necessary to consummate the Offer and the Merger and make effective the other Transactions. Without limiting the generality of the foregoing, subject to the terms and conditions of this Agreement, each Party to this Agreement shall use commercially reasonable efforts to (a) make all filings (if any) and give all notices (if any) required to be made and given by such Party pursuant to any Material Contract in connection with the Offer and the Merger and the other Transactions to the extent requested in writing by Parent, (b) seek each Consent (if any) required to be obtained pursuant to any Material Contract by such Party in connection with the Transactions to the extent requested in writing by Parent; provided, however, each of the Parties acknowledges and agrees that obtaining any such consent or approval shall not, in and of itself, be a condition to the Offer or the Merger and (c) seek to lift any restraint, injunction or other legal bar to the Offer or the Merger brought by any third Person against such Party. Notwithstanding anything in this Section 6.7 to the contrary, neither Parent, the Company nor any of their respective Subsidiaries shall be required to pay any consent or other similar fee, payment or consideration, make any other concession or provide any additional security (including a guaranty), to obtain any third party consents.

6.8    Disclosure. The initial press release relating to this Agreement shall be a joint press release issued by the Company and Parent, and thereafter Parent and the Company shall consult with each other before issuing any further press release(s) or otherwise making any public statement or making any announcement to Company Associates (to the extent not previously issued or made in accordance with this Agreement) with respect to the Offer, the Merger, this Agreement or any of the other Transactions and shall not issue any such press release, public statement or announcement to Company Associates without the other Party’s written consent. Notwithstanding the foregoing: (a) each Party may, without such consultation or consent, make any public statement in response to questions from the press, analysts, investors or those attending industry conferences, make internal announcements to employees and make disclosures in Company SEC Documents, so long as such statements substantially reiterate (and are not inconsistent with) previous press releases, public disclosures or public statements made jointly by the Parties (or individually, if approved by the other Party); (b) a Party may, without the prior consent of the other Party but subject to giving advance notice to the other Party and consulting with the other Party with respect to the content thereof, issue any such press release or make any such public announcement or statement that, after consultation with outside legal counsel, is determined to be required by Legal Requirement; (c) the Company need not consult with Parent in connection with such portion of any press release, public statement or filing to be issued or made pursuant to Section 5.3(d); and (d) neither Party need consult with the other in connection with such portion of any press release, public statement or filing to be issued with respect to any Acquisition Proposal or Company Adverse Change Recommendation (but without limiting the Company’s obligations under Section 5.3 or Section 6.1).

6.9    Takeover Laws.

action, having the effect of permanently restraining, enjoining or otherwise prohibiting the acceptance for payment of Shares pursuant to the Offer or the Merger or making the consummation of the Offer or the Merger illegal, which order, decree, ruling or other action shall be final and nonappealable; provided, however, that the right to terminate this Agreement pursuant to this Section 8.1(c) shall not be available to any Party whose material breach of this Agreement has caused or resulted in such final and nonappealable order, injunction, decree, ruling or other action;

(d)    by Parent, if the Board of Directors shall have effected a Company Adverse Change Recommendation;

(g)    by the Company, if (i) a breach of any representation or warranty contained in this Agreement or failure to perform any covenant or obligation in this Agreement on the part of Parent or Purchaser shall have occurred, in each case, if such breach or failure would reasonably be expected to prevent Parent or Purchaser from consummating the Offer and the Merger and such breach or failure cannot be cured by Parent or Purchaser, as applicable, by the End Date, or, if capable of being cured in such time period, shall not have been cured within forty-five (45) days of the date the Company gives Parent written notice of such breach or failure to perform; provided, however, that the Company shall not have the right to terminate this Agreement pursuant to this Section 8.1(g) if the Company is then in material breach of any representation, warranty, covenant or obligation hereunder or (ii) Purchaser fails to commence the Offer on or prior to the 10th business day following the date of this Agreement or if Purchaser fails to consummate the Offer in accordance with the terms of this Agreement.

8.2    Effect of Termination. In the event of the termination of this Agreement as provided in Section 8.1, written notice thereof shall be given to the other Party or Parties,

53

specifying the provision hereof pursuant to which such termination is made, and this Agreement shall be of no further force or effect and there shall be no liability on the part of Parent, Purchaser or the Company or any of their respective former, current or future officers, directors, partners, stockholders, managers, members or Affiliates following any such termination; provided, however, that (a) the final sentence of Section 1.2(b), the final sentence of Section 5.1(a), this Section 8.2, Section 8.3 and Section 9 (other than Section 9.5(b)) shall survive the termination of this Agreement and shall remain in full force and effect, (b) the Confidentiality Agreement shall survive the termination of this Agreement and shall remain in full force and effect in accordance with its terms and (c) except as set forth in Section 8.3, the termination of this Agreement shall not relieve any Party from any liability for fraud or willful and material breach of this Agreement prior to termination.

(a)    Except as set forth in this Section 8.3, all fees and expenses incurred in connection with this Agreement and the Transactions shall be paid by the Party incurring such expenses, whether or not the Offer and Merger are consummated.

(b)    In the event that:

(ii)    this Agreement is terminated by Parent pursuant to Section 8.1(d), the Company shall pay to Parent or its designee the Termination Fee by wire transfer of same day funds within one business day after such termination; or

(iii)    (x) this Agreement is terminated by Parent or the Company pursuant to Section 8.1(b) (but in the case of a termination by the Company, only if at such time Parent would not be prohibited from terminating this Agreement pursuant to the proviso to Section 8.1(b)) or by Parent pursuant to Section 8.1(f) resulting from a willful and material breach of any covenant in this Agreement, (y) any Person shall have publicly disclosed a bona fide Acquisition Proposal, or such Acquisition Proposal has otherwise been communicated to the Board of Directors or the Company’s stockholders and shall have become publicly known, after the date hereof and prior to such termination and such Acquisition Proposal has not been unconditionally withdrawn prior to such termination and (z) within twelve (12) months of such termination the Board of Directors shall have approved or recommended any Acquisition Proposal (regardless of when made), and the Company shall have entered into a definitive agreement with respect to such Acquisition Proposal, which shall have been consummated (provided that for purposes of this clause (z) the references to “20%” in the definition of “Acquisition Proposal” shall be deemed to be references to “50%”), the Company shall pay to Parent or its designee the Termination Fee by wire transfer of same day funds prior to the consummation of such Acquisition Proposal.

54

(c)    It is understood that in no event shall the Company be required to pay the Termination Fee on more than one occasion. As used herein, “Termination Fee” shall mean a cash amount equal to $160,000,000. In any circumstance in which the Termination Fee becomes due and payable and is paid by the Company in accordance with this Section 8.3, the Termination Fee shall be deemed to be liquidated damages for, and the sole and exclusive monetary remedy available to Parent and Purchaser in connection with, any and all losses or damages suffered or incurred by Parent, Purchaser, any of their respective Affiliates or any other Person in connection with this Agreement (collectively, “Parent Related Parties”) (and the termination hereof), the Transactions (and the abandonment thereof) or any matter forming the basis for such termination, and none of Parent, Purchaser or any of their respective Affiliates shall be entitled to bring or maintain any claim, action or proceeding against the Company or any of its Affiliates arising out of or in connection with this Agreement, any of the Transactions or any matters forming the basis for such termination. For the avoidance of doubt, Parent and Purchaser may seek specific performance to cause the Company to consummate the Transactions in accordance with Section 9.5 or the payment of the Termination Fee pursuant to this Section 8.3(c), but in no event shall Parent or Purchaser be entitled to both (i) specific performance to cause the Company to consummate the Transactions in accordance with Section 9.5 and (ii) the payment of the Termination Fee pursuant to this Section 8.3(c).

(d)    Parent’s right to receive payment from the Company of the Termination Fee and any other payments pursuant to Section 8.3 shall be the sole and exclusive remedy of the Parent Related Parties against the Company and any of their respective former, current or future officers, directors, partners, stockholders, optionholders, managers, members or Affiliates (collectively, “Company Related Parties”) for any loss suffered as a result of the failure of the Offer or the Merger to be consummated or for a breach or failure to perform hereunder or otherwise, and upon payment of such amount(s), none of the Company Related Parties shall have any further liability or obligation relating to or arising out of this Agreement or the Transactions.

(e)    The Parties acknowledge (i) that the agreements contained in this Section 8.3 are an integral part of the transactions contemplated by this Agreement, (ii) that the Termination Fee is not a penalty, but a reasonable amount that will compensate Parent and Purchaser in the circumstances in which such payment is payable for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the Transactions and (iii) that, without these agreements, the Parties would not enter into this Agreement; accordingly, if the Company fails to timely pay any amount due pursuant to Section 8.3(b), and, in order to obtain the payment, Parent commences a Legal Proceeding which results in a judgment against the Company, the Company shall pay Parent its reasonable and documented costs and expenses (including reasonable and documented attorneys’ fees) in connection with such suit, together with interest on such amount at the prime rate as published in the Wall Street Journal in effect on the date such payment was required to be made through the date such payment was actually received.

9.1    Amendment. Prior to the Offer Acceptance Time, this Agreement may be amended with the approval of the respective Boards of Directors of the Company, Parent and Purchaser at any time; provided that, following the consummation of the Offer, this Agreement may not be amended in any manner that causes the Merger Consideration to differ from the Offer Price. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the Parties.

9.2    Waiver. No failure on the part of any Party to exercise any power, right, privilege or remedy under this Agreement, and no delay on the part of any Party in exercising any power, right, privilege or remedy under this Agreement, shall operate as a waiver of such power, right, privilege or remedy. No single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy. No Party shall be deemed to have waived any claim arising out of this Agreement, or any power, right, privilege or remedy under this Agreement, unless the waiver of such claim, power, right, privilege or remedy is expressly set forth in a written instrument duly executed and delivered on behalf of such Party and any such waiver or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure. At any time prior to the Offer Acceptance Time, Parent and Purchaser, on the one hand, and the Company, on the other hand, may (a) extend the time for the performance of any of the obligations or other acts of the other, (b) waive any breach of the representations and warranties of the other contained herein or in any document delivered pursuant hereto or (c) waive compliance by the other with any of the agreements or covenants contained herein. Any such extension or waiver shall be valid only if is expressly set forth in a written instrument duly executed and delivered on behalf of the Party or Parties to be bound thereby, but such extension or waiver or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure. The rights and remedies provided herein shall be cumulative and not exclusive of any rights or remedies provided by any Legal Requirement except to the extent set forth in Section 8.3(d).

9.3    No Survival of Representations and Warranties. None of the representations and warranties contained in this Agreement, the Company Disclosure Schedule or in any certificate or schedule or other document delivered by any Person pursuant to this Agreement shall survive the Merger.

9.4    Entire Agreement; Counterparts. This Agreement (including its Exhibits, Annexes and the Company Disclosure Schedule) and the Confidentiality Agreement constitute the entire agreement and supersede all prior agreements and understandings, both written and oral, among or between any of the Parties and their respective Affiliates, with respect to the subject matter hereof and thereof. The Confidentiality Agreement shall survive the execution and delivery of this Agreement except that the restrictions on contact and restrictions on disclosure (to the extent to be included in SEC filings in connection with the Transactions) in the

56

Confidentiality Agreement shall terminate immediately following the execution and delivery of this Agreement solely for purposes of permitting the actions contemplated hereby to be consummated. This Agreement may be executed in one or more counterparts, including by facsimile or by email with .pdf attachments, all of which shall be considered one and the same agreement, and shall become effective when one or more counterparts have been signed by each of the Parties and delivered to the other Parties.

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

(a)    This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws thereof. In any action or proceeding arising out of or relating to this Agreement or any of the Transactions: (i) each of the Parties irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Chancery Court of the State of Delaware and any state appellate court therefrom or, if (but only if) such court lacks subject matter jurisdiction, the United States District Court sitting in New Castle County in the State of Delaware and any appellate court therefrom (collectively, the “Delaware Courts”); and (ii) each of the Parties irrevocably consents to service of process by first class certified mail, return receipt requested, postage prepaid, to the address at which such Party is to receive notice in accordance with Section 9.9. Each of the Parties irrevocably and unconditionally (1) agrees not to commence any such action or proceeding except in the Delaware Courts, (2) agrees that any claim in respect of any such action or proceeding may be heard and determined in the Delaware Courts, (3) waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the jurisdiction or laying of venue of any such action or proceeding in the Delaware Courts and (4) waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in the Delaware Courts. The Parties agree that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Legal Requirements; provided, however, that nothing in the foregoing shall restrict any Party’s rights to seek any post-judgment relief regarding, or any appeal from, such final trial court judgment.

(b)    The Parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that the Parties do not perform their obligations under the provisions of this Agreement in accordance with its specified terms or otherwise breach such provisions. Subject to the following sentence, the Parties acknowledge and agree that (i) the Parties shall be entitled to an injunction or injunctions, specific performance, or other equitable relief, to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in the courts described in Section 9.5(a) without proof of damages or otherwise, this being in addition to any other remedy to which they are entitled under this Agreement, and (ii) the right of specific performance is an integral part of the Transactions and without that right, neither the Company nor Parent would have entered into this Agreement. The right to specific enforcement hereunder shall include the right of the Company, on behalf of itself and any third party beneficiaries to this Agreement, to cause Parent and Purchaser to cause the Offer, the Merger and the other Transactions to be consummated on

57

the terms and subject to the conditions set forth in this Agreement. Each of the Parties agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief on the basis that the other Parties have an adequate remedy at law or an award of specific performance is not an appropriate remedy for any reason at law or equity. The Parties acknowledge and agree that any Party seeking an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in accordance with this Section 9.5(b) shall not be required to provide any bond or other security in connection with any such order or injunction.

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

9.6    Assignability. This Agreement shall be binding upon, and shall be enforceable by and inure solely to the benefit of, the Parties and their respective successors and permitted assigns; provided, however, that neither this Agreement nor any of the rights hereunder may be assigned by a Party without the prior written consent of the other Parties, and any attempted assignment of this Agreement or any of such rights without such consent shall be void and of no effect; provided further, however, that Parent may designate, by written notice to the Company, another wholly-owned direct or indirect Delaware corporate Subsidiary of Parent to act as Purchaser, in which event all references to Purchaser in this Agreement shall be deemed references to such other Subsidiary; provided such assignment shall not impede or delay the consummation of the Transactions or relieve Parent of its obligations hereunder. 

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

9.8    Transfer Taxes. Except as otherwise provided in Section 2.6(b), all transfer, documentary, sales, use, stamp, registration and other similar Taxes and fees imposed on the Company with respect to the transfer of Shares pursuant to the Offer or the Merger shall be borne by the Company and expressly shall not be a liability of holders of Shares, expressly

58

excluding any such Taxes imposed on the holders of Shares. The Company shall cooperate with Purchaser and Parent in preparing, executing and filing any Tax Returns with respect to such Taxes.

9.9    Notices. Any notice or other communication required or permitted to be delivered to any Party under this Agreement shall be in writing and shall be deemed properly delivered, given and received (a) upon receipt when delivered by hand, (b) two business days after being sent by registered mail or by courier or express delivery service, or (c) upon confirmation of successful transmission if sent by email followed up within one business day by dispatch pursuant to one of the other methods described herein; provided that in each case the notice or other communication is sent to the physical address or email address set forth beneath the name of such Party below (or to such other physical address or email address as such Party shall have specified in a written notice given to the other Parties):

Exhibit 99.1

GILEAD TO ACQUIRE FORTY SEVEN FOR $4.9 BILLION

– Gilead Gains Forty Seven’s Investigational Immuno-Oncology Therapy in Multiple Clinical Studies for Diseases Including Myelodysplastic Syndrome, Acute Myeloid Leukemia and Diffuse Large B-Cell Lymphoma –

– Transaction Supports Gilead’s Strategic Focus in Oncology and Gives Access to Potential New First-in-Class Program and Innovative Pipeline –

Foster City, Calif. and Menlo Park, Calif. — March 2, 2020 — Gilead Sciences, Inc. (Nasdaq: GILD) and Forty Seven, Inc. (Nasdaq: FTSV) announced today that the companies have entered into a definitive agreement pursuant to which Gilead will acquire Forty Seven for $95.50 per share in cash. The transaction, which values Forty Seven at approximately $4.9 billion, was unanimously approved by both the Gilead and Forty Seven Boards of Directors and is anticipated to close during the second quarter of 2020, subject to regulatory approvals and other customary closing conditions.

Through the addition of Forty Seven’s investigational lead product candidate, magrolimab, the acquisition will strengthen Gilead’s immuno-oncology research and development portfolio. Magrolimab is a monoclonal antibody in clinical development for the treatment of several cancers for which new, transformative medicines are urgently needed, including myelodysplastic syndrome (MDS), acute myeloid leukemia (AML) and diffuse large B-cell lymphoma (DLBCL). The investigational therapy targets CD47, a “do not eat me” signal that allows cancer cells to avoid destruction thereby permitting the patient’s own innate immune system to engulf and eradicate those cancer cells. Forty Seven presented promising results of a Phase 1b study of magrolimab in patients with MDS and AML at the American Society of Hematology meeting in December 2019. Magrolimab has the potential to be a first-in-class therapy.

“This agreement builds on Gilead’s presence in immuno-oncology and adds significant potential to our clinical pipeline,” said Daniel O’Day, Chairman and Chief Executive Officer of Gilead Sciences. “Magrolimab complements our existing work in hematology, adding a non-cell therapy program that complements Kite’s pipeline of cell therapies for hematological cancers. With a profile that lends itself to combination therapies, magrolimab could potentially have transformative benefits for a range of tumor types. We are looking forward to working with the highly experienced team at Forty Seven to help patients with some of the most challenging forms of cancer.”

“This is an exciting day for patients who may one day benefit from future anti-CD47 therapies and other immuno-oncology treatments based on our research and an exciting time for Forty Seven as this allows us to achieve our vision of helping patients defeat their cancer,” commented Mark McCamish, MD, PhD, President and Chief Executive Officer of Forty Seven. “We are pleased to join Gilead and believe that by combining our scientific expertise with Gilead’s strength in developing treatments that modify the immune system, we will be able to more rapidly advance our therapies.”

Magrolimab

Forty Seven is initially studying magrolimab in patients with MDS and AML. Additional studies are ongoing in non-Hodgkin lymphoma (NHL) and solid tumors. Magrolimab has been granted Fast Track designation by the U.S. Food and Drug Administration (FDA) for the treatment of MDS and AML, and for the treatment of relapsed or refractory DLBCL and follicular lymphoma, two forms of B-cell NHL. Magrolimab has also been granted Orphan Drug designation by the FDA for the treatment of MDS and AML and by the European Medicines Agency for the treatment of AML.

More than 400 patients have received the compound to date through clinical trials.

Ongoing Phase 1b Clinical Trial

In December 2019, Forty Seven presented promising results of a Phase 1b trial evaluating magrolimab in combination with azacitidine in untreated patients with higher risk MDS and untreated patients with AML, who are ineligible for induction chemotherapy. This has led to the initiation of a potential registrational cohort in MDS. All patients received a 1 mg/kg priming dose of magrolimab, coupled with intrapatient dose escalation to mitigate on-target anemia. Patients were then treated with full doses of azacitidine and magrolimab maintenance doses of 30 mg/kg weekly.

As of the data cutoff of November 18, 2019, 62 patients had been treated with the combination in the Phase 1b portion of the trial, including 35 patients with MDS and 27 patients with AML.

Clinical Activity Data

As of the data cutoff, 46 patients were evaluable for response assessment, including 24 patients with untreated higher-risk MDS and 22 patients with untreated AML, who were ineligible for induction chemotherapy.

Safety Data

As of the data cutoff, the combination of magrolimab and azacitidine was well-tolerated, with no evidence of increased toxicities compared to azacitidine alone. Adverse events (AEs) were consistent with prior clinical experience. No deaths were observed in the first 60 days on combination treatment and only one patient out of 62 (1.6 percent) discontinued treatment due to a treatment-related AE.

Additional Programs

Beyond magrolimab, Forty Seven is preparing to advance two additional investigational compounds into clinical testing. FSI-174, an anti-cKIT antibody, is being developed in combination with magrolimab as a novel, all-antibody conditioning regimen to address the limitations of current stem cell transplantation conditioning regimens. FSI-189, an anti-SIRPα antibody, is being developed for the treatment of cancer, as well as certain non-oncology settings, including transplantation conditioning.

Terms of the Transaction

Under the terms of the merger agreement, a wholly-owned subsidiary of Gilead will promptly commence a tender offer to acquire all of the outstanding shares of Forty Seven’s common stock at a price of $95.50 per share in cash. Following successful completion of the tender offer, Gilead will acquire all remaining shares not tendered in the offer through a second step merger at the same price as in the tender offer.

Consummation of the tender offer is subject to a minimum tender of at least a majority of outstanding Forty Seven shares plus Forty Seven shares underlying vested options, the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act and other customary conditions.

Gilead plans to pay all cash consideration for the transaction. The tender offer is not subject to a financing condition.

Citi and J.P. Morgan are acting as joint financial advisors to Gilead. Centerview Partners LLC is acting as the exclusive financial advisor to Forty Seven. Skadden, Arps, Slate, Meagher & Flom LLP is serving as legal counsel to Gilead and Cooley LLP is serving as legal counsel to Forty Seven.
