ARTICLE 2

THE OFFER

SECTION 2.1. The Offer.

(a) Provided that this Agreement shall not have been terminated in accordance with Section 9.1 and the Company is prepared in accordance with Section 2.2(a) to file with the SEC, and to disseminate to the Stockholders, the Schedule 14D-9 on the same date as Merger Sub commences the Offer, as promptly as practicable (but in no event later than 10 Business Days) after the date hereof, Merger Sub shall, and Parent shall cause Merger Sub to, commence (within the meaning of Rule 14d-2 under the Exchange Act), the Offer.

(b) The obligations of Merger Sub to, and of Parent to cause Merger Sub to, accept for payment and pay for any shares of Company Common Stock pursuant to the Offer are subject to the terms and the satisfaction or waiver (as provided in Section 2.1(c) below) of the conditions set forth in Annex I (the “Offer Conditions”). On the terms and subject to the conditions of the Offer and this Agreement, Merger Sub shall, and Parent shall cause Merger Sub to, accept and pay for all shares of Company Common Stock validly tendered and not validly withdrawn pursuant to the Offer (the “Tendered Shares”) promptly on or after the Expiration Date (and in any event within three business days (calculated as set forth in Rule 14d-1(g)(3)

under the Exchange Act)). The acceptance for payment of shares of Company Common Stock pursuant to and subject to the conditions of the Offer is referred to in this Agreement as the “Offer Closing,” and the date and time at which the Offer Closing occurs is referred to in this Agreement as the “Acceptance Time.” Parent shall provide, or cause to be provided, to Merger Sub on a timely basis funds necessary to purchase and pay for any and all shares of Company Common Stock that Merger Sub becomes obligated to accept for payment and purchase pursuant to the Offer. Parent and Merger Sub shall, and each of Parent and Merger Sub shall ensure that all of their respective controlled Affiliates shall, tender any shares of Company Common Stock held by them into the Offer.

(c) Parent and Merger Sub expressly reserve the right to waive any of the Offer Conditions other than the Minimum Condition, to increase the Offer Price or to make any other changes in the terms and conditions of the Offer not inconsistent with the terms of this Agreement; provided that, unless otherwise provided in this Agreement or previously approved by the Company in writing, Parent and Merger Sub shall not: (i) decrease the Offer Price or change the form of consideration payable in the Offer, (ii) decrease the maximum number of shares of Company Common Stock subject to or sought to be purchased in the Offer, (iii) impose conditions on the Offer in addition to the Offer Conditions or amend, modify or supplement any condition in a manner adverse to the Stockholders, (iv) waive, modify or amend the Minimum Condition, (v) amend any other term of the Offer in a manner that is materially adverse to the Stockholders or (vi) extend or otherwise change the Expiration Date except as required or permitted by Section 2.1(e). The Offer may not be terminated prior to the Expiration Date, unless this Agreement is terminated or withdrawn in accordance with Section 9.1.

(d) On the date the Offer is commenced, Merger Sub shall, and Parent shall cause Merger Sub to, file with the SEC a Tender Offer Statement on Schedule TO with respect to the Offer, which Tender Offer Statement shall include an offer to purchase, letter of transmittal, summary advertisement and other required ancillary offer documents (such Schedule TO and the documents included therein pursuant to which the Offer will be made, together with any supplements or amendments thereto, the “Offer Documents”) and cause the Offer Documents to be disseminated to the Stockholders to the extent required by applicable Law. The Company hereby consents to the inclusion of the Company Recommendation in the Offer Documents. Merger Sub shall, and Parent shall cause Merger Sub to, cause the Offer Documents to comply in all material respects with the Exchange Act, the rules and regulations thereunder, and other requirements of applicable Law. The Company shall promptly furnish to Parent and Merger Sub all information concerning the Company, the Company Subsidiaries and the Stockholders that may be required to be set forth in the Offer Documents or reasonably requested in connection with any action contemplated by this Section 2.1(d), including communication of the Offer to the record and beneficial Stockholders. Each of the parties agrees to promptly correct any information provided by it for use in the Offer Documents if and to the extent that such information shall have become false or misleading in any material respect, and to correct any material omissions therefrom, and Parent and Merger Sub further agree to take all steps necessary to cause the Offer Documents as so corrected to be filed with the SEC and disseminated to the Stockholders, in each case as and to the extent required by applicable Law. Parent and Merger Sub shall provide the Company and its counsel with any comments (including a summary of any oral comments) that Parent, Merger Sub or their counsel may receive from time to time from the SEC or its staff with respect to the Offer Documents promptly after receipt

of such comments. Except from and after a Company Adverse Recommendation Change or in connection with any disclosures by Parent or Merger Sub in response to any public announcement expressly permitted by Section 7.8(f), prior to the filing of the Offer Documents (including any amendment or supplement thereto) with the SEC or dissemination thereof to the Stockholders, or responding to any comments of the SEC with respect to the Offer Documents, Parent and Merger Sub shall provide the Company with a reasonable opportunity to review and comment on such Offer Documents or response, and Parent and Merger Sub shall give reasonable consideration to any comments provided by the Company. Parent and Merger Sub shall use reasonable best efforts to respond promptly to any such SEC comments.

(e) Unless extended or earlier terminated pursuant to and in accordance with the terms of this Agreement, the Offer shall remain open until midnight, New York City time, at the end of the 20th business day (for purposes of this Section 2.1(e), calculated in accordance with Rule 14d-1(g)(3) under the Exchange Act) following the commencement of the Offer (the “Initial Expiration Date”) or, if the period of time for which the Offer is open shall have been extended pursuant to, and in accordance with, this Agreement or as may be required by applicable Law, the time and date to which the Offer has been so extended (the Initial Expiration Date or such later time and date to which the Offer has been extended in accordance with this Agreement, the “Expiration Date”). Notwithstanding the foregoing, (i) if on the then-effective Expiration Date, the Minimum Condition has not been satisfied or any of the other Offer Conditions have not been satisfied or waived by Parent or Merger Sub if permitted hereunder, then Merger Sub shall, and Parent shall cause Merger Sub to, extend the Offer on one or more occasions in consecutive increments of not more than 10 Business Days each (the length of such period to be determined by Parent and Merger Sub in their discretion), or for such longer period as the parties may agree in order to permit the satisfaction of such Offer Conditions (subject to the right of Parent or Merger Sub to waive any Offer Conditions, other than the Minimum Condition); provided that, if all Offer Conditions other than the Minimum Condition have been satisfied or waived, Merger Sub shall not be required to extend the Offer pursuant to this clause (i) for more than 20 Business Days and (ii) Merger Sub shall, and Parent shall cause Merger Sub to, extend the Offer for the minimum period required by applicable Law, interpretation or position of the SEC or its staff or NASDAQ or its staff; provided that Merger Sub shall not in any event be required to extend the Offer beyond the Outside Date. In the event that this Agreement is validly terminated pursuant to Section 9.1, Merger Sub shall, and Parent shall cause Merger Sub to, promptly (and in any event within 24 hours of such termination), irrevocably and unconditionally terminate the Offer, shall not acquire any shares of Company Common Stock pursuant to the Offer and shall cause any depositary acting on behalf of Merger Sub to return, in accordance with applicable Law, all Tendered Shares to the registered holders thereof.

SECTION 2.2. Company Action.

(a) As promptly as practicable on the date that the Offer Documents are filed with the SEC, the Company shall, concurrently with or following the filing of the Schedule TO, file with the SEC a Solicitation/Recommendation Statement on Schedule 14D-9 pertaining to the Offer (together with any amendments or supplements thereto, the “Schedule 14D-9”) that contains the Company Recommendation and the fairness opinion delivered by Centerview Partners LLC (and a fair summary thereof), and shall promptly disseminate the Schedule 14D-9

to the Stockholders together with the Offer Documents as required by Rule 14d-9 under the Exchange Act. The Company shall cause the Schedule 14D-9 to comply in all material respects with the Exchange Act, the rules and regulations thereunder, and other requirements of applicable Law. The Schedule 14D-9 will also contain the notice of appraisal rights required to be delivered by the Company under Section 262(d)(2) of the DGCL in connection with a merger effected pursuant to Section 251(h) of the DGCL at the time the Company first files the Schedule 14D-9 with the SEC.

The Company shall provide Parent, Merger Sub and their counsel with any comments (including a summary of oral comments) that the Company or its counsel may receive from time to time from the SEC or its staff with respect to the Schedule 14D-9 promptly after receipt of such comments. Except from and after a Company Adverse Recommendation Change or in connection with any disclosures that are expressly permitted by Section 7.8(f), prior to the filing of the Schedule 14D-9 (including any amendment or supplement thereto) with the SEC or dissemination thereof to the Stockholders, or responding to any comments of the SEC with respect to the Schedule 14D-9, the Company shall provide Parent and Merger Sub with a reasonable opportunity to review and comment on such Schedule 14D-9 or response, and the Company shall give reasonable consideration to any comments provided by Parent or Merger Sub.

ARTICLE 4

CONSIDERATION; EXCHANGE OF CERTIFICATES

SECTION 4.1. Conversion of Merger Sub Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub or the Company, each share of Merger Sub capital stock will be converted into and become one fully paid and non-assessable share of common stock of the Surviving Corporation.

SECTION 4.2. Conversion of Company Common Stock. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, the Company or any Stockholder:

(a) Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than (i) any shares to be canceled pursuant to Section 4.2(b) and (ii) any Appraisal Shares (each of such shares described in clauses (i) and (ii), an “Excluded Share” and collectively, the “Excluded Shares”)) shall be canceled and shall be converted automatically into the right to receive an amount in cash equal to the Offer Price, without interest (the “Merger Consideration”). As of the Effective Time, all such shares of Company Common Stock (other than the Excluded Shares) shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of either a certificate representing any such shares of Company Common Stock (each, a “Certificate”) or book-entry shares representing such shares of Company Common Stock (“Book-Entry Shares”) shall cease to have any rights with respect thereto, except the right to receive, as the case may be, (i) the Merger Consideration payable with respect to such shares of Company Common Stock upon surrender of such Certificate or Book-Entry Shares in accordance with Section 4.3, without interest or (ii) the payment referred to in Section 4.9, in the case of each Certificate formerly representing shares of Company Common Stock or Book-Entry Shares owned by dissenting stockholders.

(b) Each share of Company Common Stock held in the treasury of the Company and each share of Company Common Stock owned by Parent or Merger Sub immediately prior to the Effective Time shall be canceled without any conversion thereof and shall cease to exist and no payment or distribution shall be made with respect thereto.

SECTION 4.3. Exchange of Certificates.

(a) Paying Agent. Prior to the Effective Time, Parent shall enter into an agreement with such bank or trust company as may be designated by Parent and reasonably acceptable to the Company to act as agent (the “Paying Agent”) for the holders of shares of Company Common Stock to receive the funds to which holders of such shares of Company Common Stock (other than the Excluded Shares) shall become entitled pursuant to Section 4.2.

At or immediately following (but no later than one Business Day after) the Effective Time, Parent shall deposit, or shall cause to be deposited, with the Paying Agent for the benefit of the holders of shares of Company Common Stock (other than Excluded Shares), a cash amount in immediately available funds necessary for the Paying Agent to make payments under Section 4.2(a) (such cash being hereinafter referred to as the “Exchange Fund”). The Exchange Fund shall not be used for any other purpose. The Exchange Fund shall, pending its disbursement to the Stockholders, be invested by the Paying Agent as directed by Parent; provided that (i) no such investment or losses thereon shall relieve Parent from making the payments required by Section 4.2 or affect the amount of Merger Consideration payable in respect of the shares of Company Common Stock and (ii) no such investment shall have maturities that could prevent or delay payments to be made pursuant to this Agreement. Any and all interest or other amounts earned with respect to such funds shall become part of the Exchange Fund, and any amounts in excess of the amounts payable under Section 4.2 shall be promptly returned to Parent. The Surviving Corporation shall (and Parent shall cause the Surviving Corporation to) pay all charges and expenses of the Paying Agent, in connection with the exchange of shares of Company Common Stock and the payment of the Merger Consideration in respect of the shares of Company Common Stock.

(b) Exchange Procedures. As promptly as practicable (but no later than two Business Days) after the Effective Time, Parent and the Surviving Corporation shall cause the Paying Agent to mail to each holder of record of Certificates and to each holder of record of Book-Entry Shares, in each case whose shares were converted into the right to receive the Merger Consideration pursuant to Section 4.2(a), (i) a letter of transmittal which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Paying Agent and which shall be in such form and have such other customary provisions as Parent may reasonably specify and are reasonably acceptable to the Company (ii) instructions for use in surrendering the Certificates or Book-Entry Shares in exchange for the Merger Consideration payable with respect thereto. Upon surrender to the Paying Agent of a Certificate for cancelation, together with a duly completed and validly executed letter of transmittal or receipt of an “agent’s message” by the Paying Agent (or such other evidence, if any, of transfer as the Paying Agent may reasonably request) in the case of Book-Entry Shares, the holder of such Certificate or Book-Entry Shares shall receive in exchange therefor the amount of cash which the shares of Company Common Stock theretofore represented by such Certificate or book-entry entitle such holder to receive pursuant to the provisions of this Article 4 and the Certificate or Book-Entry Shares so surrendered shall forthwith be canceled. Until so surrendered or transferred, as the case may be, each such Certificate or Book-Entry Share shall represent after the Effective Time for all purposes only the right to receive the Merger Consideration. No interest shall be paid or shall accrue on any cash payable to holders of Certificates or Book-Entry Shares pursuant to the provisions of this Article 4. In the event of a transfer of ownership of Company Common Stock that is not registered in the transfer records of the Company, payment may be made to a Person other than the Person in whose name the Certificate or Book-Entry Shares so surrendered are registered if such Certificate shall be properly endorsed or otherwise be in proper form for transfer or such Book-Entry Shares shall be properly transferred and the Person requesting such issuance shall pay any transfer or other Taxes required by reason of the payment to a Person other than the registered holder of such Certificate or Book-Entry Shares or establish to the satisfaction of Parent that such Tax has been paid or is not applicable.

(c) No Further Ownership Rights in Company Common Stock. The Merger Consideration paid upon the surrender or exchange of Certificates and Book-Entry Shares in accordance with the terms of this Article 4 shall be deemed to have been paid in full satisfaction of all rights pertaining to the shares of Company Common Stock theretofore represented by such Certificates or book entries, and, after the Effective Time, there shall be no further registration of transfers on the stock transfer books of the Company of the shares of Company Common Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates or Book-Entry Shares are presented to the Surviving Corporation or the Paying Agent for any reason, they shall be canceled and exchanged as provided in this Article 4, except as otherwise provided by applicable Law.

(d) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of Certificates or Book-Entry Shares for six months after the Effective Time shall be delivered to Parent or one of its Affiliates, upon demand, and any holders of Certificates or Book-Entry Shares who have not theretofore complied with this Article 4 shall thereafter look only to Parent (subject to abandoned property, escheat or similar Laws, as general creditors thereof) for payment of their claim for Merger Consideration, without any interest thereon and subject to any withholding of Taxes required by applicable Law, in respect of such holder’s surrender of their Certificates or Book-Entry Shares and compliance with the procedures in Section 4.3(b).

(e) No Liability. None of Parent, Merger Sub, the Company, the Surviving Corporation, the Paying Agent or their respective Affiliates shall be liable to any Person in respect of any Merger Consideration or any cash from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If any Certificate or Book-Entry Share shall not have been surrendered prior to the earlier of (i) two years after the Effective Time and (ii) immediately prior to the date on which the Merger Consideration payable with respect to the shares of Company Common Stock represented by such Certificate or Book-Entry Share pursuant to this Article 4 would otherwise escheat to or become the property of any Governmental Authority, then any such Merger Consideration shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation, free and clear of all claims or interest of any Person previously entitled thereto.

(f) Lost, Stolen or Destroyed Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such Person 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, the Paying Agent shall, subject to such Person’s compliance with the exchange procedures set forth in Section 4.3(b) (other than the surrender of a Certificate), issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration payable with respect to the shares of Company Common Stock represented by such Certificate in accordance with this Article 4.

SECTION 4.4. Company Equity Awards.

(a) Treatment of Company Stock Options. Immediately prior to the Effective Time, each Company Stock Option under any Stock Plan shall, to the extent unvested, become fully vested and exercisable effective immediately prior to, and contingent upon, the Effective Time. At the Effective Time, by virtue of the Merger and without any further action on the part of the holders thereof or the parties hereto, each Company Stock Option shall be canceled and, in exchange therefor, each former holder of any such canceled Company Stock Option shall be entitled to receive, in consideration of the cancelation of such Company Stock Option and in settlement therefor, a payment in cash (subject to any applicable withholding or other Taxes required by applicable Law) of an amount equal to the product of (i) the total number of shares of Company Common Stock subject to such Company Stock Option immediately prior to such cancelation and (ii) the excess, if any, of the Merger Consideration over the exercise price per share subject to such Company Stock Option immediately prior to such cancelation (such amounts payable hereunder being referred to as the “Option Payments”). No holder of a Company Stock Option that, as of immediately prior to such cancelation, has an exercise price per share that is equal to or greater than the Merger Consideration shall be entitled to any payment with respect to such canceled Company Stock Option. From and after the Effective Time, each Company Stock Option shall no longer be exercisable by the former holder thereof, but shall only entitle such holder to the payment of the corresponding Option Payment, if any. On the first applicable payroll payment date following the Closing or, if such payroll payment date is less than five days after the Closing, as promptly as practicable thereafter (but in no event later than five days after such payroll payment date), the Surviving Corporation shall make (or cause to be made) by a payroll payment and subject to withholding, if any, as described in Section 4.8, to each holder of Company Stock Options, such holder’s Option Payment.

(b) Treatment of Company RSUs. Immediately prior to the Effective Time, each Company RSU under any Stock Plan shall, to the extent unvested, become fully vested effective immediately prior to, and contingent upon, the Effective Time. At the Effective Time, by virtue of the Merger and without any further action on the part of the holders thereof or the parties hereto, each Company RSU shall be canceled and, in exchange therefor, each former holder of any such canceled Company RSU shall be entitled to receive, in consideration of the cancelation of such Company RSU and in settlement therefor, a payment in cash (subject to any applicable withholding or other Taxes required by applicable Law) of an amount equal to the product of (i) the total number of shares of Company Common Stock subject to such Company RSU immediately prior to such cancelation and (ii) the Merger Consideration (such amounts payable hereunder being referred to as the “RSU Payments”). On the first applicable payroll payment date following the Closing or, if such payroll payment date is less than five days after the Closing, as promptly as practicable thereafter (but in no event later than five days after such payroll payment date), the Surviving Corporation shall make (or cause to be made) by a payroll payment and subject to withholding, if any, as described in Section 4.8, to each holder of Company RSUs, such holder’s RSU Payment.

(c) Termination of Stock Plans. As of the Effective Time, all Stock Plans and equity awards shall be terminated and no further shares of Company Common Stock, Company Stock Options, Company RSUs, equity interests or other rights with respect to shares of stock of the Company shall be granted thereunder.

(d) Board Actions. Prior to the Effective Time, the Company Board (or, if appropriate, any committee thereof) shall adopt appropriate resolutions and take all other actions necessary and appropriate (including obtaining any required consents) to effect the transactions described in this Section 4.4.

SECTION 4.5. Employee Stock Purchase Plan. The Company, the Company Board and the Compensation Committee thereof, as applicable, shall take all actions necessary to terminate the Company’s 2016 Employee Stock Purchase Plan (the “ESPP”) and all outstanding rights thereunder as of the day immediately prior to the Expiration Date, contingent upon the occurrence of the Closing, and to otherwise effectuate the treatment of the ESPP as contemplated in this Section 4.5. From and after the date hereof, the Company shall (a) take all actions necessary to ensure that (i) no new participants are permitted to participate in the ESPP and that participants may not increase their payroll deductions or purchase elections from those in effect on the date of this Agreement and (ii) except for the offering or purchase period (if any) under the ESPP that is in effect on the date hereof (the “Final Offering Period”), no offering or purchase period shall be authorized, continued or commenced following the date hereof and (b) provide notice to participants describing the treatment of the ESPP pursuant to this Section 4.5. If the Effective Time occurs during the Final Offering Period, the Final Offering Period shall terminate no later than the day immediately prior to the Expiration Date, and the Company shall cause the exercise date applicable to the Final Offering Period to accelerate and occur on such termination date with respect to any then-outstanding purchase rights. Notwithstanding anything to the contrary herein, (x) all amounts allocated to each participant’s account under the ESPP at the end of the Final Offering Period shall thereupon be used to purchase whole shares of Company Common Stock under the terms of the ESPP for such offering period, which shares of Company Common Stock shall be canceled at the Effective Time in exchange for the right to receive the Merger Consideration in accordance with Section 4.2(a) as promptly as practicable following the purchase of shares of Company Common Stock and (y) the Company shall return to each participant the funds, if any, that remain in such participant’s account after such purchase.

SECTION 4.6. Further Action. The parties agree to take all necessary action to cause the Merger to become effective as soon as practicable following the Offer Closing without a meeting of the Stockholders, as provided in Section 251(h) of the DGCL.

SECTION 4.7. Adjustments to Prevent Dilution. Without limiting the other provisions of this Agreement, in the event that, during the period between the date hereof and the Effective Time, the number of outstanding shares of Company Common Stock or securities convertible or exchangeable into or exercisable for shares of Company Common Stock shall be changed into a different number of shares or securities or a different class, including as a result of a reclassification, stock split (including a reverse stock split), stock dividend or distribution, recapitalization, merger, issuer tender or exchange offer or other similar transaction, then the Offer Price, the Merger Consideration and any other amounts payable pursuant to this Agreement shall be equitably adjusted, without duplication, to reflect such change; provided that, in any case, nothing in this Section 4.7 shall be construed to permit the Company to take any action with respect to its securities that is prohibited by the terms of this Agreement.

SECTION 4.8. Withholding Rights. Notwithstanding any provision contained herein to the contrary, each of Parent, Merger Sub, the Surviving Corporation and the Paying Agent shall be entitled to deduct and withhold from the consideration otherwise payable to any Person pursuant to this Agreement such amounts as it is required to deduct and withhold with

respect to the making of such payment under the Code or any provision of state, local or foreign Tax Law. Any amounts so deducted and withheld by Parent, Merger Sub, the Surviving Corporation or the Paying Agent, as the case may be and paid over to the appropriate Governmental Authority, shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which Parent, Merger Sub, the Surviving Corporation or the Paying Agent, as the case may be, made such deduction and withholding. Parent shall use commercially reasonable efforts to notify the Company in writing at least five Business Days prior to the Closing Date of any obligation to withhold Tax on any payments with respect to Company Common Stock, other than (a) with respect to U.S. backup withholding Taxes, (b) as a result of a failure by any person to provide a U.S. federal withholding certificate on IRS Form W-9 or the applicable IRS Form W-8, or of the Company to comply with Section 7.16(a) or (c) with respect to a payment in the nature of compensation to be made to service providers or former service providers of the Company. Parent and the Company shall each use commercially reasonable efforts to cooperate with each other to mitigate and reduce such withholding to the extent permitted by applicable Tax Law.

SECTION 4.9. Appraisal Rights. Notwithstanding anything in this Agreement to the contrary, shares of Company Common Stock that are outstanding immediately prior to the Effective Time and that are held by any Person who is entitled to demand and properly demands appraisal of such shares (“Appraisal Shares”) pursuant to, and who complies in all respects with, Section 262 of the DGCL shall not be converted into the right to receive Merger Consideration and shall entitle the holder only to payment for such Appraisal Shares in accordance with and to the extent provided by Section 251(h) and Section 262 of the DGCL; provided that if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to appraisal under Section 262 of the DGCL, then such Appraisal Shares shall automatically be deemed to have been converted as of the Effective Time into, and become exchangeable solely for the right to receive, Merger Consideration as provided in Section 4.2(a). The Company shall serve notice to Parent within one Business Day of any demands received by the Company for appraisal of any shares of Company Common Stock, and Parent shall have the right to participate in and direct (provided, that such direction may not result in a binding obligation on the part of the Company that is effective prior to the Effective Time) all negotiations and proceedings with respect to such demands. The Company shall not, without the prior written consent of Parent, make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of the foregoing. Any cash deposited with the Paying Agent pursuant to Section 4.3(a) with respect to shares of Company Common Stock that become Appraisal Shares shall be returned to Parent upon demand therefor.

(c) During the Pre-Closing Period, subject to applicable Law, the Company shall (i) give Parent prompt notice in the event that FDA inspects the Company or any Company Subsidiary or the Company or any Company Subsidiary otherwise receives notice of any planned inspection and give Parent the right (to the extent permitted by applicable Law) to participate in any such inspection; (ii) use reasonable best efforts to provide Parent with advance notice of any planned meetings or conference calls the Company or any Company Subsidiary has with (1) the

FDA or its advisory committees, the EMA or its advisory committees, or any other similar Governmental Authority and (2) subject to the receipt of any prior consent of the Collaboration Partners required under any applicable Contract, any joint development or executive committee of the Company’s or any Company Subsidiary’s and their respective Collaboration Partners’ Representatives that has been established pursuant to any Contract with such Collaboration Partners with respect to the development, marketing, distribution, manufacturing, labeling, commercialization and sales of Company Products pursuant to such Contract; and (iii) consider in good faith any comments or other input timely provided by Parent in respect of the foregoing.

SECTION 7.7. Access to Information; Confidentiality.

(a) During the Pre-Closing Period, the Company shall, and shall cause the Company Subsidiaries and the Representatives of the Company and the Company Subsidiaries to, afford to Parent, Merger Sub and their respective Representatives reasonable access during normal business hours of the Company to its officers, employees, agents, properties, facilities, books, records, Contracts and other assets, and shall promptly furnish to Parent, Merger Sub and their respective Representatives copies of all existing financial, operating and other data and information as such Persons may from time to time reasonably request; provided that any such access (including to employees) shall be conducted at Parent’s expense, at a reasonable time, under the supervision of the Company’s President and Chief Operating Officer or other Person designated by the Company, and in such a manner as to not to interfere unreasonably with the normal operation of the business of the Company. All requests for information and access (including to employees) made pursuant to this Section 7.7(a) shall be directed to the Company’s President and Chief Operating Officer or other Person designated by the Company. The Company shall instruct its Representatives to cooperate with Parent and Merger Sub in their investigation of the Company and the Company Subsidiaries. No additional investigations or disclosures shall affect the Company’s representations and warranties contained herein, or limit or otherwise affect the remedies available to Parent and Merger Sub pursuant to this Agreement.

(b) Nothing herein shall require the Company or any Company Subsidiary to disclose any information to Parent if such disclosure would, in the Company’s reasonable discretion (i) jeopardize any attorney client or other legal privilege (provided that the Company will nonetheless provide Parent and the applicable Representatives of Parent with appropriate information regarding the factual basis underlying any circumstances that resulted in the preparation of such privileged analyses so long as such privilege will not be jeopardized thereby) or (ii) contravene any applicable Law, fiduciary duty or binding agreement entered into prior to the date of this Agreement, including any confidentiality agreement to which the Company or any Company Subsidiary is a party (provided that the Company shall use its commercially reasonable efforts to obtain the consent of any such agreement’s counterparty to such inspection or disclosure). The Company and Parent will each use its commercially reasonable efforts to make appropriate substitute arrangements to permit reasonable disclosure under circumstances in which the restrictions of the preceding sentence apply. In addition, nothing in this Section 7.7 shall require the Company or any Company Subsidiary to disclose any information to Parent hereunder if such information relates to the applicable portions of the minutes of the meetings of the Company Board (including any presentations or other materials prepared by or for the Company Board) where the Company Board discussed (i) the transactions contemplated by this Agreement or any similar transaction involving the sale of the Company, or a material portion of its assets, to, or combination of the Company with, any other Person, (ii) any Acquisition Proposal or (iii) any Intervening Event.

(c) The information disclosed pursuant to this Section 7.7 shall be treated in accordance with the provisions of the Confidentiality Agreement, which shall remain in full force and effect in accordance with its terms.

SECTION 7.8. No Solicitation.

(a) At all times during the Pre-Closing Period, the Company shall not, shall cause the Company Subsidiaries not to, and shall not authorize or knowingly permit its and the Company Subsidiaries’ respective Representatives to, directly or indirectly (other than with respect to Parent or Merger Sub): (i) solicit, initiate, propose or knowingly encourage any inquiries or the submission of any proposal that constitutes, or could reasonably be expected to lead to, an Acquisition Proposal or otherwise knowingly facilitate any effort or attempt to make an Acquisition Proposal; (ii) except as otherwise expressly permitted by this Section 7.8(a), enter into, continue or otherwise participate in any discussions or negotiations regarding, furnish to any Third Party any information or data relating to, afford access to the business, properties, assets, books or records of the Company and the Company Subsidiaries in connection with, or otherwise cooperate with any Person with respect to, any Acquisition Proposal or any inquiry, proposal or offer that could reasonably be expected to lead to an Acquisition Proposal (other than, solely in response to an inquiry that did not result from or arise in connection with a breach of this Section 7.8(a), to refer the inquiring person to this Section 7.8 and to limit its communication exclusively to such referral); (iii) grant any waiver, amendment or release of or under, or fail to enforce, any confidentiality, standstill or similar agreement (or any confidentiality, standstill or similar provision of any other Contract); (iv) enter into any letter of intent, agreement, contract, commitment or agreement in principle with respect to an Acquisition Proposal or enter into any agreement, contract or commitment requiring the Company to abandon, terminate or fail to consummate the Transactions; or that would otherwise materially impede the ability of Parent and Merger Sub to consummate the Offer Closing and the Merger or (v) resolve, propose or agree to do any of the foregoing. Notwithstanding anything to the contrary contained in this Agreement, if in response to a bona fide written Acquisition Proposal

made by a Third Party after the date hereof (x) not resulting from a breach and (y) in circumstances not involving a material breach of this Section 7.8, the Company Board or a committee thereof determines in good faith (after consultation with outside legal counsel and a financial advisor of nationally recognized reputation) that such Acquisition Proposal constitutes, or could reasonably be expected to lead to, a Superior Proposal and, after consultation with outside legal counsel, that the failure to take such action would be inconsistent with the fiduciary duties of the Company Board under applicable Law, then the Company may, at any time prior to the Offer Closing (but in no event after such time), enter into an Acceptable Confidentiality Agreement with such Third Party making such an Acquisition Proposal and thereafter (1) furnish information and data with respect to the Company and the Company Subsidiaries and afford access to the business, personnel, properties, assets, books and records of the Company and the Company Subsidiaries to, and (2) enter into, maintain and participate in discussions or negotiations with, the Third Party making such Acquisition Proposal and its Representatives; provided, that the Company will concurrently provide to Parent any information and data concerning the Company or any Company Subsidiary or access provided to such Third Party which was not previously made available to Parent. The Company shall ensure that its Representatives are aware of the provisions of this Section 7.8(a). Without limiting the foregoing, it is agreed that any violation of the foregoing restrictions by any Company Subsidiary or any Representative of the Company or any Company Subsidiary shall be deemed to be a breach of this Section 7.8 by the Company; provided, that solely for purposes of this sentence only, except as otherwise set forth on Section 7.8 of the Company Disclosure Letter, “Representative” shall not include any employee of the Company or any Company Subsidiary who is below the level of senior director (as indicated on the Company’s employee census set forth in Section 5.12(b) of the Company Disclosure Letter) or any outside consultant of the Company or any Company Subsidiary, in each case, who is not acting at the direction or permission of the Company or any Representative who is aware of the provisions of this Section 7.8 (such employees and contractors that are not included, the “Specified Persons”). The Company shall not terminate, waive, amend, release or modify any material provision of any Acceptable Confidentiality Agreement.

(b) In addition to the other obligations of the Company set forth in this Section 7.8, the Company shall as promptly as practicable, and in any event no later than the earlier of 48 hours or one Business Day after receipt thereof, notify Parent in writing of any Acquisition Proposal or any inquiry, proposal or offer that expressly contemplates or could reasonably be expected to lead to an Acquisition Proposal, which notification shall include (i) a copy of the applicable written Acquisition Proposal, inquiry, proposal or offer (or, if oral, a summary of the material terms and conditions of such Acquisition Proposal, inquiry, proposal or offer) and (ii) the identity of the Third Party making such Acquisition Proposal. The Company shall thereafter keep Parent reasonably informed on a reasonably current basis of any material developments, discussions or negotiations regarding any such Acquisition Proposal, and the material terms and conditions thereof (including any change in price or form of consideration or other material amendment thereto), including by providing a copy of any proposed letter of intent, definitive agreement or similar documents relating to such Acquisition Proposal, or drafts thereof, containing any such material terms and conditions that is exchanged between the Third Party (or its Representatives) making such Acquisition Proposal and the Company (or its Representatives).

(c) Except as expressly permitted by Section 7.8(d), neither the Company Board nor any committee thereof shall (i) withhold, fail to include in (or remove from) the Schedule 14D-9, withdraw, qualify or modify (or publicly propose or resolve to withhold, fail to include in (or remove from) the Schedule 14D-9, withdraw, qualify or modify), in a manner adverse to Parent, the Company Recommendation, (ii) adopt, approve, recommend, submit to the Stockholders or declare advisable or make any recommendation other than a rejection of (or publicly propose to adopt, approve, recommend, submit to the Stockholders or declare advisable, or make any recommendation other than a rejection of), any Acquisition Proposal or (iii) take any action to exempt any Person (other than Parent or its Subsidiaries) or any action taken by any Person (other than Parent or its Subsidiaries) from any Takeover Provision (any action described in this Section 7.8(c) being referred to as a “Company Adverse Recommendation Change”).

(d) Notwithstanding anything to the contrary contained in this Agreement, at any time during the Pre-Closing Period, the Company Board may effect a Company Adverse Recommendation Change or terminate this Agreement to enter into a Specified Agreement, in each case if, and only if, (i) the Company has complied with this Section 7.8 with respect to such Company Adverse Recommendation Change or Specified Agreement or any Acquisition Proposal relating thereto, (ii) the Company Board determines in good faith, after consultation with the Company’s outside legal counsel, that the failure to make the Company Adverse Recommendation Change or terminate this Agreement to enter into a Specified Agreement would be inconsistent with the fiduciary duties of the Company Board under applicable Law, (iii) the Company has given Parent written notice of the Company Board’s intention to make a Company Adverse Recommendation Change or terminate this Agreement to enter into a Specified Agreement not earlier than 11:59 p.m. Tokyo time on the fifth Business Day in Japan after Parent receives such written notice (a “Change of Recommendation Notice”), (iv) if not in connection with an Intervening Event pursuant to Section 7.8(e), the decision to make a Company Adverse Recommendation Change shall be in connection with an Acquisition Proposal or with the Company’s intent to terminate this Agreement to enter into a Specified Agreement, and the Company shall have complied with clauses (1) through (5), as follows: (1) prior to giving effect to clauses (2) through (5), the Company Board shall have determined that such Acquisition Proposal is a Superior Proposal, (2) the Company shall have made available to Parent in writing the material terms and conditions of such Acquisition Proposal and a copy of any proposed letter of intent, definitive agreement or similar documents containing such material terms and conditions, (3) the Company shall have negotiated in good faith with Parent (and caused its Representatives to negotiate with Parent), to the extent that Parent desires to negotiate, during the five-Business Day period provided in the foregoing clause (iii) of this Section 7.8(d) with respect to such proposed revisions to this Agreement or other proposals made by Parent, if any, so that the Acquisition Proposal would no longer constitute a Superior Proposal, (4) after considering the results of negotiations with Parent and taking into account the proposals that Parent has committed to in writing that are irrevocable until at least six hours after the expiration of the five-Business Day period provided in the foregoing clause (iii) of this Section 7.8(d), if any, after consultation with its outside legal counsel and a financial advisor of nationally recognized reputation, the Company Board shall have determined in good faith that such Acquisition Proposal remains a Superior Proposal, and, after consultation with its outside legal counsel, that the failure to make the Company Adverse Recommendation Change or terminate this Agreement to enter into a Specified Agreement would be inconsistent with the fiduciary duties of the

Company Board under applicable Law and (5) if the Company intends to terminate this Agreement to enter into a Specified Agreement, the Company shall have complied with Section 9.1(d)(i). For clarity, the provisions of this Section 7.8(d) shall also apply to any material amendment to any Acquisition Proposal (except that any reference to five Business Days shall instead be three Business Days) or any successive Acquisition Proposals.

(e) Notwithstanding anything to the contrary contained in this Agreement, at any time during the Pre-Closing Period, the Company Board may make a Company Adverse Recommendation Change with respect to an Intervening Event, if and only if: (i) the Company Board determines in good faith, after consultation with the Company’s outside legal counsel, that the failure to make the Company Adverse Recommendation Change would be inconsistent with the fiduciary duties of the Company Board under applicable Law; (ii) Parent shall have received from the Company written notice not later than 11:59 p.m. Tokyo time on the fifth Business Day prior to the making of any Company Adverse Recommendation Change, describing the Intervening Event in reasonable detail; (iii) during the five-Business Day period provided in the foregoing clause (ii), the Company shall have negotiated in good faith with Parent (and caused its Representatives to negotiate with Parent), to the extent that Parent desires to negotiate, with respect to any proposed revisions to this Agreement or other proposals made by Parent, if any, that would obviate the requirement to make a Company Adverse Recommendation Change; and (iv) after considering the results of negotiations with Parent and taking into account the proposals that Parent has committed to in writing that are irrevocable until at least six hours after the expiration of the five-Business Day period provided in the foregoing clause (ii), if any, after consultation with its outside legal counsel, the Company Board shall have determined in good faith that the failure to make the Company Adverse Recommendation Change would be inconsistent with the fiduciary duties of the Company Board under applicable Law.

(f) Nothing in this Section 7.8, or in Section 7.4, shall prohibit the Company from (i) taking and disclosing a position contemplated by Rule 14d-9 or Rule 14e-2(a) under the Exchange Act or complying with Item 1012(a) of Regulation M-A under the Exchange Act, (ii) making any disclosure to the Stockholders, if the Company Board determines in good faith, after consultation with outside legal counsel, that the failure to take such position or make such disclosure would be inconsistent with its fiduciary duties under applicable Law or any disclosure requirement under applicable Law or (iii) making any disclosure that constitutes a “stop, look and listen” communication pursuant to Rule 14d-9(f) promulgated under the Exchange Act; provided that this Section 7.8(f) shall not permit the Company Board to make a Company Adverse Recommendation Change, except to the extent permitted by Section 7.8(c) or Section 7.8(d) (it being understood that, without limitation, (x) any “stop, look and listen” letter or similar communication pursuant to Rule 14d-9(f) under the Exchange Act and (y) any disclosure of information to the Company’s stockholders that describes the Company’s receipt of an Acquisition Proposal, and the provisions of this Agreement that apply thereto and contains a statement that expressly reaffirms the Company Board has not effected a Company Adverse Recommendation Change, shall be deemed to not be a Company Adverse Recommendation Change).

(g) The Company shall, and shall cause the Company Subsidiaries and the Company’s and the Company Subsidiaries’ respective Representatives to, (i) immediately cease and cause to be terminated any existing solicitations, encouragements, facilitations, discussions or negotiations with any Third Party conducted heretofore by the Company, any Company Subsidiary or their respective Representatives with respect to an Acquisition Proposal, (ii) promptly (but in no event later than one Business Day following the execution of this Agreement) terminate access to any physical or electronic data rooms relating to a possible Acquisition Proposal, and (iii) promptly (but in no event later than two Business Days following the execution of this Agreement) request the return from all such Persons, or the destruction by such Persons, of all copies of confidential information previously provided to such Persons by or on behalf of the Company, any Company Subsidiary or on their behalf by their respective Representatives during the 18-month period preceding the date of this Agreement in connection with discussions of a possible Acquisition Proposal (disregarding, for this purpose, clause (iii) of the definition thereof).

SECTION 7.9. Indemnification and Insurance.

(a) After the Effective Time, the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, fulfill and honor all rights and obligations to indemnification by the Company (including advancement of expenses) now existing in favor of each Person who is now, or has been at any time prior to the date hereof or who becomes prior to the Effective Time an officer or director of the Company or any Company Subsidiary (each an “Indemnified Party”) as provided in the Company Charter Documents, in each case as in effect on the date hereof, or pursuant to any other agreements in effect on the date hereof including as set forth on Section 7.9 of the Company Disclosure Letter, accurate and complete copies of which have been made available to Parent, shall be assumed by the Surviving Corporation in the Merger, without further action, at the Effective Time and shall survive the Merger and shall remain in full force and effect in accordance with their terms.

(b) After the Effective Time, the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, to the fullest extent permitted under applicable Law, indemnify, defend and hold harmless each Indemnified Party against any and all losses, claims, damages, liabilities, costs, fees, expenses (including fees and expenses of legal counsel, which shall be advanced as they are incurred; provided, that the Indemnified Party shall have made an undertaking to repay such amounts advanced if, and only if and to the extent that, it shall ultimately be determined that such Indemnified Party was not entitled to indemnification under the agreements set forth on Section 7.9 of the Company Disclosure Letter, the Company Charter Documents and the DGCL), Judgments, fines, penalties or liabilities (including amounts paid in settlement or compromise) in connection with or arising in whole or in part out of actions, omissions, suits or other proceedings (whether civil or criminal, and including any proceeding before any administrative or legislative body) in which such Indemnified Party may be involved or with which he or she may be threatened (regardless of whether as a named party or as a participant other than as a named party, including, without limitation, as a witness) (an “Indemnified Proceeding”) by reason of such Indemnified Party’s being or having been such director or officer or an employee or agent of the Company or otherwise in connection with any action taken or not taken at the request of the Company, whether or not the Indemnified Party continues in such position at the time such Indemnified Proceeding is brought or threatened and at, or at any time prior to, the Effective Time (including any Indemnified Proceeding relating in whole or in part to the Transactions or relating to the enforcement of this provision or any other indemnification or advancement right of any Indemnified Party). The Surviving Corporation

shall, and Parent shall cause the Surviving Corporation to, pay all expenses, including reasonable attorneys’ fees, that may be incurred by Indemnified Parties in connection with their enforcement of their rights under this Section 7.9. The Surviving Corporation’s obligations under Section 7.9(a) and this Section 7.9(b) shall continue in full force and effect for a period of six years from the Effective Time; provided, however, that all rights to indemnification, exculpation and advancement of expenses in respect of any claim asserted or made within such period shall continue until the final disposition of such claim.

(c) The Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, maintain the officers’ and directors’ liability insurance in respect of acts or omissions occurring on or prior to the Effective Time covering each such Person currently covered by the Company’s officers’ and directors’ liability insurance policy on terms with respect to coverage and amount no less favorable than those of such policy in effect on the date hereof; provided that in satisfying its obligation under this Section 7.9(c), the Surviving Corporation shall not be obligated to pay an amount per year (the “Maximum Amount”) in excess of 250% of the annual premium the Company paid in its most recent renewal prior to the date of this Agreement and if such premiums for such insurance would at any time exceed the Maximum Amount, then the Surviving Corporation shall cause to be maintained policies of insurance that, in the Surviving Corporation’s good faith judgment, provide the maximum coverage available at an annual premium equal to the Maximum Amount. The provisions of the immediately preceding sentence shall be deemed to have been satisfied if prepaid “tail” or “runoff” policies have been obtained by the Company prior to the Effective Time, which policies provide such directors and officers with coverage for an aggregate period of six years with respect to claims arising from acts or omissions that occurred on or before the Effective Time, including, in respect of the Transactions; provided, however, that the amount paid for such prepaid policies does not exceed the Maximum Amount. If such prepaid policies have been obtained prior to the Effective Time, the Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, maintain such policies in full force and effect for their full term, and continue to honor the obligations thereunder.

(d) The provisions of this Section 7.9 are (i) intended to be for the benefit of, and shall be enforceable by, each Indemnified Party, his or her heirs and his or her representatives and (ii) in addition to, and not in substitution for, any other rights to indemnification or contribution that any such individual may have under any certificate of incorporation or bylaws, by contract or otherwise. The obligations of Parent and the Surviving Corporation under this Section 7.9 shall survive the Offer Closing and the consummation of the Merger and shall not be terminated or modified in such a manner as to adversely affect any Indemnified Party to whom this Section 7.9 applies without the consent of such affected Indemnified Party (it being expressly agreed that the Indemnified Parties to whom this Section 7.9 applies shall be third party beneficiaries of this Section 7.9, each of whom may enforce the provisions of this Section 7.9).

(e) In the event that the Surviving Corporation 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 its properties and assets to any Person, or if Parent dissolves the Surviving Corporation, then, and in each such case, Parent shall cause proper provision to be made so that the successors and assigns of the Surviving Corporation assume the obligations set forth in this Section 7.9.

SECTION 7.10. Section 16 Matters. Prior to the Effective Time, the Company and the Company Board shall take all such steps as may be required to cause any dispositions of equity securities of the Company (including derivative securities) in connection with this Agreement by each Company director or officer who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Company’s equity securities to be exempt under Rule 16b-3 promulgated under the Exchange Act.

SECTION 7.11. Transaction Litigation. The Company shall promptly advise Parent in writing of any Transaction Litigation and shall keep Parent informed on a reasonably prompt basis regarding any such Transaction Litigation. The Company shall give Parent the opportunity to (a) participate in the defense, prosecution, settlement or compromise of any Transaction Litigation, and (b) consult with counsel to the Company regarding the defense, prosecution, settlement or compromise with respect to any such Transaction Litigation. For purposes of this Section 7.11, “participate” means that Parent will be kept reasonably apprised of proposed strategy and other significant decisions with respect to the Transaction Litigation (to the extent that the attorney-client privilege between the Company and its counsel is not undermined or otherwise adversely affected), and Parent may offer comments or suggestions with respect to such Transaction Litigation which the Company shall consider in good faith; provided that the Company shall not settle or compromise or agree to settle or compromise any Transaction Litigation without Parent’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed), except (i) to the extent such settlement is fully covered by the Company’s insurance policies (other than any applicable deductible) or (ii) such settlement relates solely to the provision of additional disclosure in the Schedule 14D-9, but in each case of clauses (i) and (ii) only if such settlement would not result in the imposition of any restriction on the business or operations of the Company or its affiliates and contains a full and unconditional release of and covenant not to sue all parties and their Representatives.

SECTION 7.12. Deregistration; Stock Exchange Delisting. Prior to the Effective Time, the Company shall cooperate with Parent and use its reasonable best efforts to take, or cause to be taken, all actions, and do or cause to be done all things, necessary, proper or advisable on its part under applicable Law and rules and policies of NASDAQ to cause the delisting of the Company and of the Company Common Stock from NASDAQ as promptly as practicable after the Effective Time and deregistration of the Company Common Stock under the Exchange Act as promptly as practicable after such delisting, and in any event no more than 10 days after the Closing Date. The Company shall not cause the Company Common Stock to be delisted from NASDAQ prior to the Effective Time.

SECTION 7.13. Takeover Provisions. If any Takeover Provision becomes or is deemed to be applicable to the Company, Parent, Merger Sub, the Offer, the Merger or any other Transaction, then each of the Company, Parent, Merger Sub, and their respective Boards of Directors shall grant such approvals and take such actions as are necessary so that the Transactions may be consummated as promptly as practicable on the terms contemplated hereby and otherwise act to render such Takeover Provision inapplicable to the foregoing.

SECTION 7.14. Obligations of Merger Sub. Parent shall cause Merger Sub to comply in all respects with each of the representations, warranties, covenants, obligations, agreements and undertakings made or required to be performed by Merger Sub in accordance with the terms of this Agreement, the Offer, the Merger, and the other Transactions.

SECTION 7.15. Rule 14d-10 Matters. Prior to the Offer Closing, the Company (acting through the compensation committee of the Company Board) shall take such steps as may be required to approve as an “employment compensation, severance or other employee benefit arrangement” within the meaning of Rule 14d-10(d)(1) under the Exchange Act (a) each Stock Plan, (b) the treatment of Company Stock Options and Company RSUs in accordance with the terms set forth in this Agreement, the applicable Stock Plan and any applicable Company Employee Benefit Plans and (c) each other Company Employee Benefit Plan that provides compensation or benefits in connection with the Transactions, for purposes of Rule 14d-10(d)(1) under the Exchange Act and to satisfy the requirements of the non-exclusive safe harbor set forth in Rule 14d-10(d) under the Exchange Act.

(b) The Company shall cause any material Tax Sharing Agreement to which the Company or any Company Subsidiary is party (other than any Tax Sharing Agreement to which only the Company and Company Subsidiaries are party) to be terminated with respect to the Company and any applicable Company Subsidiary on or prior to the Closing Date.

(iii) if the Offer shall have expired (and not been extended) without the acceptance for payment of shares of Company Common Stock pursuant to the Offer; provided that a party shall not be permitted to terminate this Agreement pursuant to this Section 9.1(b)(iii) if a breach in any material respect by such party of any provision of this Agreement shall have primarily caused the failure of the acceptance for payment of the shares of Company Common Stock pursuant to the Offer;

(i) (1) a Company Adverse Recommendation Change shall have occurred, (2) at any time after receipt or public announcement of an Acquisition Proposal, the Company Board shall have failed to reaffirm the Company Recommendation as promptly as practicable (but in any event within five Business Days (or, if the Outside Date is fewer than five Business Days after the Company’s receipt of such request, by the close of business on the Business Day immediately preceding the Outside Date)) after receipt of any written request to do so by Parent (provided that Parent is only allowed to make two such reaffirmation requests with respect to each such public announcement prior to the Acceptance Time, and other than in connection with the commencement of a tender offer or exchange offer) or (3) a tender offer or exchange offer subject to Regulation 14D under the Exchange Act relating to the Company Common Stock shall have been commenced by a Third Party and the Company shall not have sent to the Stockholders pursuant to Rule 14e-2 under the Exchange Act, within five Business Days after the commencement of such tender offer or exchange offer, a statement on Schedule 14D-9 reaffirming the Company Recommendation and recommending that the Stockholders reject such tender or exchange offer;

(ii) a breach of any representation or warranty or failure to perform any covenant or agreement on the part of the Company set forth in this Agreement shall have occurred that would cause the Offer Conditions set forth in paragraph (c)(iii) or paragraph (c)(iv) of Annex I (other than in the case of a breach of the covenants or agreements set forth in Section 7.8), as applicable, not to be satisfied; provided that, for purposes of this Section 9.1(c)(ii), if such a breach is curable by the Company within the earlier of the Outside Date and 20 Business Days of the date Parent gives the Company notice of such breach and the Company is continuing to use its reasonable best efforts to cure such breach, then Parent may not terminate this Agreement under this Section 9.1(c)(ii) on account of such breach unless such breach shall remain uncured upon the earlier of the Outside Date and the expiration of such 20 Business Day period; provided, further, that Parent shall not be entitled to terminate this Agreement pursuant to this Section 9.1(c)(ii) if either Parent or Merger Sub is in breach of its obligations under this Agreement such that the Company would be entitled to terminate this Agreement pursuant to Section 9.1(d)(ii); or

(iii) the Company shall have Willfully Breached its obligations under Section 7.8;

(d) by the Company by written notice to Parent;

(i) in order to accept a Superior Proposal and enter into the Specified Agreement relating to such Superior Proposal, if (1) such Superior Proposal shall not have resulted from any breach of Section 7.8 with respect to such Superior Proposal and any Acquisition Proposal that was a precursor thereto, (2) the Company Board, after satisfying all of the requirements set forth in Section 7.8(d), shall have authorized the Company to enter into a binding written definitive acquisition agreement providing for the consummation of a transaction constituting a Superior Proposal (a “Specified Agreement”) and (3) the Company shall have paid the Termination Fee concurrently, and have entered into the Specified Agreement concurrently with, the termination of this Agreement pursuant to this Section 9.1(d)(i);

(ii) if a breach of any representation or warranty or failure to perform any covenant or agreement on the part of Parent or Merger Sub set forth in this Agreement shall have occurred, which breach or failure to perform has had, or would reasonably be expected to have, a Parent Material Adverse Effect; provided that, for purposes of this Section 9.1(d)(ii), if such a breach is curable by Parent within the earlier of the Outside Date and 20 Business Days of the date the Company gives Parent notice of such breach and Parent is continuing to use its reasonable best efforts to cure such breach, then the Company may not terminate this Agreement under this Section 9.1(d)(ii) on account of such breach unless such breach shall remain uncured upon the earlier of the Outside Date and the expiration of such 20 Business Day period; provided further that the Company shall not be entitled to terminate this Agreement pursuant to this Section 9.1(d)(ii) if the Company is in breach of its obligations under this Agreement such that Parent would be entitled to terminate this Agreement pursuant to Section 9.1(c)(ii); or

(iii) if Merger Sub fails to commence the Offer in accordance with Section 2.1(a) or if the Merger Sub fails to consummate the Offer in accordance with the terms of this Agreement and, in each case, such failure remains uncured at the expiration of five Business Days after the date the Company gives Parent notice of such failure; provided that the right to terminate this Agreement pursuant to this Section 9.1(d)(iii) shall not be available to the Company if the Company’s breach of its obligations under Section 2.2 is the primary cause of, or resulted in, Merger Sub’s failure to commence the Offer in accordance with the terms of this Agreement.

Any written notice of termination pursuant to this Section 9.1 shall specify the provision of this Section 9.1 pursuant to which such termination is being effected.

SECTION 9.2. Effect of Termination. If terminated pursuant to Section 9.1, this Agreement shall be of no further force or effect without liability of any party (or any stockholder or Representative of such party) to each other party hereto; provided that the provisions of this Section 9.2, Section 7.7(c), Section 9.3 and Article 10 shall survive any termination hereof pursuant to Section 9.1. Notwithstanding the foregoing or any other provision of this Agreement to the contrary, none of Parent, Merger Sub or the Company shall be relieved or released from any liabilities or damages arising out of any fraud or Willful Breach of any provision of this Agreement or any other agreement delivered in connection herewith. For purposes of this Agreement, “Willful Breach” means an intentional and willful material breach, or an intentional and willful material failure to perform, in each case that is the consequence of an act or omission by a party with the knowledge that the taking of such act or failure to take such act would cause a breach of this Agreement; provided that (1) for purposes of this “Willful Breach” definition, all Representatives (excluding Specified Persons) shall be deemed to have been made aware of the requirements of Section 7.8(a) and (2) the failure of Parent or Merger Sub to accept for payment and pay for the Tendered Shares promptly following the Expiration Date after all Offer Conditions have been satisfied or waived in accordance with the terms of this Agreement shall constitute a Willful Breach by Parent and Merger Sub, and Parent shall be liable to the Company for such Willful Breach as provided herein notwithstanding any termination of this Agreement. The Confidentiality Agreement shall survive the termination of this Agreement and shall remain in full force and effect in accordance with its terms.

SECTION 9.3. Termination Fee and Expenses.

(a) Except as otherwise set forth in this Section 9.3, all costs and Expenses incurred in connection with this Agreement and the Transactions shall be paid by the party incurring such costs or Expenses, whether or not the Transactions are consummated; provided that Parent shall pay all filing fees payable pursuant to the HSR Act or any other Antitrust Laws.

(b) In the event that:

(i) this Agreement is terminated by Parent pursuant to Section 9.1(c)(i) or Section 9.1(c)(iii);

(ii) this Agreement is terminated by the Company pursuant to Section 9.1(d)(i); or

(iii) (1) this Agreement is terminated by Parent, Merger Sub or the Company pursuant to Section 9.1(b)(i) (solely if, at the final expiration date of the Offer, the conditions set forth in clauses (b) and (c)(i) of Annex I shall have been satisfied; provided that if the Company’s breach of its obligations under this Agreement is the principal cause of the failure of the foregoing conditions to be satisfied, such conditions will deemed to have been satisfied for the purposes of this Section 9.3(b)(iii)(1)), Section 9.1(b)(iii) (solely if, at the final expiration date of the Offer, the conditions set forth in clauses (b) and (c)(i) of Annex I shall have been satisfied; provided that if the Company’s breach of its obligations under this Agreement is the principal cause of the failure of the foregoing conditions to be satisfied, such conditions will deemed to have been satisfied for the purposes of this Section 9.3(b)(iii)(1)) or Section 9.1(c)(ii) as a result of a breach of a covenant in this Agreement by the Company, (2) after the date of this Agreement an Acquisition Proposal shall have been made to the Company or shall have been publicly made directly to the Stockholders, in each case, not withdrawn prior to the date of termination of this Agreement pursuant to Section 9.1, and (3) the Company or any Company Subsidiary (A) consummates an Acquisition Proposal within 12 months after such termination or (B) the Company or any Company Subsidiary enters into a definitive agreement to effect an Acquisition Proposal within 12 months after such termination that (x) is subsequently consummated (regardless of the timing of such consummation) or (y) was proposed or publicly announced prior to the termination of this Agreement, in each case in this Section 9.3(b)(iii), replacing “15%” in the definition of Acquisition Proposal with “50%”;

(iv) then, in any such event under clause (i), (ii) or (iii) of this Section 9.3(b), the Company shall pay to Parent, in cash at the time specified in the next sentence, a nonrefundable termination fee of $104,100,000.00 (the “Termination Fee”). Any payment of the Termination Fee required to be made pursuant to: (1) Section 9.3(b)(i) shall be made to Parent within one Business Day after termination of this Agreement by Parent or

the Company as set forth in Section 9.3(b)(i); (2) Section 9.3(b)(ii) shall be made to Parent immediately prior to and as a condition to such termination of this Agreement by the Company as set forth in Section 9.3(b)(ii); and (3) Section 9.3(b)(iii) shall be made to Parent concurrently with the occurrence of the applicable event described in clause (3) of Section 9.3(b)(iii). All payments under this Section 9.3(b) shall be made by wire transfer of immediately available funds to an account to be designated by Parent. In the event that Parent receives full payment pursuant to this Section 9.3(b), then, receipt of the Termination Fee shall be deemed to be liquidated damages for any and all losses or damages suffered or incurred by Parent, Merger Sub, any of their respective Affiliates or any other Person in connection with this Agreement (and the termination hereof), the Transactions (and the abandonment thereof) or any matter forming the basis for such termination, and none of Parent, Merger Sub, any of their respective Affiliates or any other Person shall be entitled to bring or maintain any claim, action or proceeding against the Company or any of its Affiliates for damages or any equitable relief 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, any payment made by the Company under this Section 9.3(b) shall be payable only once with respect to this Section 9.3(b) and not in duplication even though such payment may be payable under one or more provisions hereof.

(c) The Company and Parent acknowledge that the agreements contained in Section 9.3(b) are an integral part of the Transactions, and that, without those agreements, the Company, Parent and Merger Sub would not enter into this Agreement. Accordingly, if the Company fails to make payment of any amount payable under Section 9.3(b) within the applicable time period specified in Section 9.3(b), as the case may be, and Parent commences a Proceeding to collect such amount that results in a judgment against the Company, the Company shall reimburse Parent for its fees and expenses (including reasonable attorneys’ fees and expenses) incurred in connection with such Proceeding and shall pay interest on the amount of the payment at the prime rate as published in The Wall Street Journal in effect on the date the amount was payable pursuant to Section 9.3(b), with such interest to accrue beginning on the date such amount first was payable pursuant to Section 9.3(b), to the date of payment.

(b) No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any right, power or privilege.

SECTION 10.4. Governing Law; Jurisdiction.

Process in any such suit, action or proceeding may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court.

SECTION 10.7. Assignment; Third Party Beneficiaries.

(a) The provisions of this Agreement shall be binding upon and shall inure to the benefit of the parties and their respective successors and assigns.

(b) Nothing in this Agreement, expressed or implied, is intended to confer on any Person other than the parties hereto or their respective heirs, successors, executors, administrators and assigns any rights, remedies, obligations or liabilities under or by reason of this Agreement, except for (i) the provisions of Section 7.9 with respect to the Persons referred to therein and (ii) (A) if the Acceptance Time occurs, the right of the Company’s stockholders to receive the Offer Price in accordance with the terms of the Offer Documents and (B) if the Effective Time occurs, the right of the Company’s stockholders to receive the Merger Consideration in accordance with the terms of this Agreement, the right of the holders of Company Stock Options and Company RSUs to receive the payments contemplated by Section 4.4 and the rights of participants in the ESPP to receive the applicable treatment pursuant to Section 4.5, in each case which shall inure to the benefit of such Persons or holders, as applicable, benefiting therefrom who shall be third-party beneficiaries thereof and who may enforce the covenants contained therein.

Upon such a determination, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the Transactions be consummated as originally contemplated to the fullest extent possible.

SECTION 10.9. Entire Agreement; No Reliance.

(a) This Agreement and the Confidentiality Agreement constitute the entire agreement between the parties with respect to the subject matter of this Agreement and supersede all prior agreements and understandings, both oral and written, between the parties with respect to the subject matter of this Agreement.

(b) Each party hereto agrees that, except for the representations and warranties contained in Article 5 (as modified by the Company Disclosure Letter), and Article 6 of this Agreement, none of the Company, Parent or Merger Sub makes any other representations or warranties and each hereby disclaims any other representations or warranties made by itself or any of its Representatives, with respect to the execution and delivery of this Agreement or the Transactions, notwithstanding the delivery or disclosure to any other party or any other party’s Representatives of any document or other information with respect to any one or more of the foregoing, including, in the case of the Company, any projections, forecasts, estimates, plans or budgets or future revenues, expenses or expenditures, future results of operations (or any component thereof), future cash flows (or any component thereof) or future financial condition (or any component thereof) of the Company or the Company Subsidiary or the future business, operations or affairs of the Company or the Company Subsidiary heretofore or hereafter delivered to or made available to Parent, except to the extent and as expressly covered by a representation and warranty made in this Agreement.

The parties agree that irreparable damage would occur and that the parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, except as expressly provided in the following sentence. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches or threatened breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in the Delaware Courts and, in any action for specific performance, each party waives the defense of adequacy of a remedy at law and waives any requirement for the securing or posting of any bond in connection with such remedy, this being in addition to any other remedy to which they are entitled at law or in equity (subject to the limitations set forth in this Agreement). The parties hereto further agree that (i) by seeking the remedies provided for in this Section 10.10, a party shall not in any respect waive its right to seek any other form of relief that may be available to a party under this Agreement (including monetary damages) for breach of any of the provisions of this Agreement or in the event that this Agreement has been terminated or in the event that the remedies provided for in this Section 10.10 are not available or otherwise are not granted, and (ii) nothing set forth in this Section 10.10 shall require any party hereto to institute any Proceeding for (or limit any party’s right to institute any Proceeding for) specific performance under this Section 10.10 prior or as a condition to exercising any termination right under Article 9 (and pursuing damages after such termination).

SECTION 10.11. Remedies. Except as otherwise provided in this Agreement, any and all remedies expressly conferred upon a party to this Agreement will be cumulative with, and not exclusive of, any other remedy contained in this Agreement, at law or in equity. The exercise by a party to this Agreement of any one remedy will not preclude the exercise by it of any other remedy.

Notwithstanding any other provisions of the Offer, but subject to the terms and conditions set forth in the Agreement, in addition to Merger Sub’s right to extend, amend or terminate the Offer in accordance with the provisions of this Agreement, neither Parent nor Merger Sub shall be required to accept for payment or, subject to any applicable rules and regulations of the SEC, including Rule 14e-1(c) under the Exchange Act (relating to Merger Sub’s obligation to pay for or return Tendered Shares promptly after termination or withdrawal of the Offer), pay for any Tendered Shares, if immediately prior to the Expiration Date (as it may have been extended pursuant to Section 2.1(e)):

(a) there shall not have been validly tendered and not validly withdrawn that number of shares of Company Common Stock (excluding shares irrevocably accepted for purchase pursuant to the Offer that have not yet been “received” by the “depository”, as such terms are defined by Section 251(h) of the DGCL) that, when added to the shares of Company Common Stock then owned by Parent and its controlled Affiliates, would represent one share more than one half of all shares of Company Common Stock outstanding at the Expiration Date (such condition in this paragraph (a), the “Minimum Condition”);

(b) any waiting period (and any extension thereof) applicable to the consummation of the Offer and the Merger under the HSR Act shall not have been terminated or shall not have expired;

(c) any of the following events, conditions, circumstances, state of facts or developments shall exist or has occurred and be continuing:

(i) any Judgment preventing the consummation of the Offer or the Merger shall have been issued by any Governmental Authority of competent jurisdiction and remain in effect, or there shall be any Law enacted or deemed applicable to the Offer or the Merger that makes consummation of the Offer or the Merger illegal;

(ii) the Company and Parent shall have agreed in writing that the Offer or the Agreement be terminated, or the Agreement shall have been terminated in accordance with its terms;

(iii) (1) any of the representations and warranties of the Company set forth in Section 5.1, Section 5.2(f), Section 5.3(a), Section 5.3(b)(i), Section 5.4, Section 5.10, Section 5.13 or Section 5.23 shall not be true and correct in all material respects as of the date of the Agreement and as of the Expiration Date as though made on and as of such date (except to the extent expressly made as of an earlier date, in which case as of such earlier date), (2) any of the representations and warranties of the Company set forth in Section 5.2(a), (c) or (d) shall not be true and correct in all respects (other than de minimis inaccuracies) as of the date of the Agreement and as of the Expiration Date as though made on and as of such date (except to the extent expressly made as of an earlier

date, in which case as of such earlier date), (3) any of the representations and warranties of the Company set forth in Section 5.7(a) shall not be true and correct in all respects as of the date of the Agreement and as of the Expiration Date as though made on and as of such date (except to the extent expressly made as of an earlier date, in which case as of such earlier date) or (4) any representations and warranties of the Company set forth in the Agreement (other than those listed in the preceding clause (c)(iii)(1), clause (c)(iii)(2) or clause (c)(iii)(3)) shall not be true and correct (without giving effect to any limitation on any representation or warranty indicated by the words “Company Material Adverse Effect,” “in all material respects,” “in any material respect,” “material” or “materially”) as of the date of the Agreement and as of the Expiration Date as though made on and as of such date (except to the extent expressly made as of an earlier date, in which case as of such earlier date), except, in the case of this clause (c)(iii)(4), where the failure of any such representations and warranties to be so true and correct would not, and would not be reasonably expected to, have, individually or in the aggregate, a Company Material Adverse Effect;

(iv) the Company shall have failed to perform or comply in any material respect with any obligation, agreement or covenant required to be performed or complied with by it under the Agreement prior to the Expiration Date and such failure remains uncured; or

(v) since the date of the Agreement, there shall have occurred any event, condition, change, occurrence or development of a state of facts that has had, or would reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect; or

(d) Parent shall not have received a certificate signed on behalf of the Company by the chief executive officer or chief financial officer of the Company to the effect that none of the conditions in paragraphs (c)(iii), (c)(iv), and (c)(v) of this Annex I shall have occurred and be continuing.

The foregoing conditions are for the sole benefit of Parent and Merger Sub, may be asserted by Parent or Merger Sub regardless of the circumstances giving rise to any such conditions, and may be waived by Parent or Merger Sub in whole or in part at any time and from time to time in their sole discretion; provided that the Minimum Condition may be waived by Parent and Merger Sub only with the prior written consent of the Company, which may be granted or withheld in the Company’s sole discretion. The failure by Parent or Merger Sub at any time to exercise any of the foregoing rights shall not be deemed a waiver of any such right and each such right shall be deemed an ongoing right which may be asserted at any time and from time to time. All capitalized terms used but not defined in this Annex I shall have the meanings ascribed to them in the Agreement to which this Annex I is attached.

Neither any amendment nor repeal of this Article VII, nor the adoption of any provision of the Corporation’s Certificate of Incorporation inconsistent with this Article VII, shall eliminate, reduce, or otherwise adversely affect any limitation on the personal liability of a director of the Corporation existing at the time of such amendment, repeal or adoption of such an inconsistent provision.
