The Company shall be the Surviving Company in the Merger (the “Initial Surviving Company”), and the separate corporate existence of the Company shall continue unaffected by the Merger, except as set forth in Article IV. The Merger shall have the effects specified in the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all property, rights, privileges, immunities, powers and franchises of the Company and Merger Sub I shall vest in the Initial Surviving Company, and all debts, liabilities and duties of the Company and Merger Sub I shall become the debts, liabilities and duties of the Initial Surviving Company.

(b) The Subsequent Merger. Immediately following the Merger, Parent shall cause the Initial Surviving Company to be merged with and into Merger Sub II (the “Subsequent Merger”) and the separate corporate existence of the Initial Surviving Company shall thereupon cease. Merger Sub II shall be the surviving limited liability company in the Subsequent Merger (sometimes hereinafter referred to as the “Surviving Company”), and the separate corporate existence of Merger Sub II shall continue unaffected by the Subsequent Merger, except as set forth in Article IV. The Subsequent Merger shall have the effects specified in the DLLCA and the DGCL.

(Eastern Time) on the date (the “Closing Date”) that is the second (2nd) Business Day following the day on which the last to be satisfied or waived of the conditions set forth in Article VIII (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the fulfillment or waiver of those conditions) shall be satisfied or waived in accordance with this Agreement.

2.3 Effective Time.

As soon as practicable following the Closing, the parties hereto shall cause a Certificate of Merger (the “First Delaware Certificate of Merger”) to be executed, acknowledged and filed with the Secretary of State of the State of Delaware as provided in Section 251 of the DGCL to effect the Merger. The Merger shall become effective at the time when the Delaware Certificate of Merger has been duly filed with the Secretary of State of the State of Delaware or at such later time as may be agreed by the parties in writing and specified in the First Delaware Certificate of Merger (the “Effective Time”).

(b) The Subsequent Merger. Immediately following the Effective Time, Parent shall cause a Certificate of Merger (the “Second Delaware Certificate of Merger”) to be executed, acknowledged and duly filed by Merger Sub II with the Secretary of State of the State of Delaware as provided in Section 18-209 of the DLLCA to effect the Subsequent Merger. The Subsequent Merger shall become effective immediately following the Effective Time (the “Subsequent Effective Time”) upon duly filing the Second Delaware Certificate of Merger with the Delaware Secretary of State on the Closing Date.

2.4 Tax Consequences. For U.S. federal income tax purposes, it is intended that the Merger and the Subsequent Merger be treated as a single integrated transaction that will qualify as a “reorganization” within the meaning of Section 368(a) of the Code, and this Agreement is intended to be and is adopted as a plan of reorganization for the purposes of Sections 354 and 361 of the Code.

ARTICLE V

Effects of the Merger

5.1 Effect on Capital Stock. At the Effective Time, as a result of the Merger and without any action on the part of Parent, Merger Sub I, Merger Sub II, the Company or any holder of any Company Capital Stock:

(a) Conversion of Company Capital Stock. Each Company Share issued and outstanding immediately prior to the Effective Time (other than (1) Company Shares owned by Parent, Merger Sub I, Merger Sub II or any other direct or indirect wholly owned Subsidiary of Parent, or Company Shares owned by the Company or any direct or indirect wholly owned Subsidiary of the Company, and in each case not held on behalf of third parties, and (2) Company Shares that are owned by Stockholders (“Dissenting Stockholders”) who have properly made and not withdrawn a demand for appraisal rights pursuant to Section 262 of the DGCL or Chapter 13 of the CGCL (the Company Shares referred to in clauses (1) and (2), the “Excluded Shares”)) shall be converted into the right to receive the Per Share Merger Consideration. At the Effective Time, all of the Company Shares shall cease to be outstanding, shall be cancelled and shall cease to exist, and each certificate (a “Certificate”) formerly representing any of the Company Shares (other than Excluded Shares) shall thereafter represent only the right to receive the Per Share Merger Consideration, without interest. With respect to the Per Share Closing Consideration component of the Per Share Merger Consideration, at the election of each Stockholder in accordance with the procedures set forth in Section 5.5(b), each Company Share shall represent the right to receive the following:

(i) for each Company Share with respect to which the Standard Election has been made (or deemed to have been made) and not been revoked pursuant to Section 5.5(b), the Per Share Standard Election Consideration;

(ii) for each Company Share with respect to which the Cash Election has been made and not been revoked pursuant to Section 5.5(b), the Per Share Cash Election Consideration; or

(iii) for each Company Share with respect to which the Stock Election has been made and not been revoked pursuant to Section 5.5(b), the Per Share Stock Election Consideration.

(b) Cancellation of Excluded Shares. Each Excluded Share shall, by virtue of the Merger and without any action on the part of the holder of such Excluded Share, cease to be outstanding, be cancelled without payment of any consideration therefor and shall cease to exist, subject to any rights the holder thereof may have under Section 5.5(g).

(c) Merger Sub I Common Stock. At the Effective Time, each share of common stock, par value $0.01 per share, of Merger Sub I issued and outstanding

immediately prior to the Effective Time shall be converted into one share of common stock, par value $0.01 per share, of the Initial Surviving Company. From and after the Effective Time, any and all certificates representing the common stock of Merger Sub I shall be deemed for all purposes to represent the number of shares of common stock of the Initial Surviving Company into which they were converted in accordance with the preceding sentence.

(d) Merger Sub II LLC Interests. At the Subsequent Effective Time, each share of common stock, par value $0.01 per share, of the Initial Surviving Company issued and outstanding immediately following the Effective Time shall be cancelled and cease to exist and no consideration shall be paid or payable in respect thereof, and (ii) each limited liability company interest of Merger Sub II shall be unaffected by the Subsequent Merger and shall remain outstanding as a limited liability company interest in the Surviving Company.

(e) Certain Adjustments. If, between the date of this Agreement and the Effective Time, the outstanding shares of Parent Common Stock shall have been changed into a different number of shares or a different class of shares by reason of any stock dividend, subdivision, reclassification, stock split, reverse stock split, combination or exchange of shares, or any similar event shall have occurred (other than in connection with the Merger), then the Aggregate Stock Merger Consideration shall be equitably adjusted, without duplication, to proportionally reflect such change; provided that nothing in this Section 5.1(e) shall be construed to permit Parent to take any of the foregoing actions with respect to the Parent Common Stock to the extent otherwise prohibited by the terms of this Agreement, including Section 7.1(c).

(f) No Fractional Shares. Notwithstanding anything to the contrary contained in this Agreement, no fractional shares of Parent Common Stock shall be issued to the holders of Company Shares in connection with the Merger and any such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a holder of shares of Parent Common Stock. Parent shall pay to each Holder of Company Shares converted pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of Parent Common Stock (after aggregating all shares represented by the Certificates delivered by such holder), in lieu thereof and upon surrender thereof, an amount in cash (without interest) equal to the product obtained by multiplying (i) the fraction of a share of Parent Common Stock to which such holder would otherwise be entitled (after taking into account all Company Shares held by such holder immediately prior to the Effective Time) by (ii) the Parent Trading Price (the “Fractional Share Cash Amount”).

5.2 Treatment of Company Options and Warrants.

(a) Company Options.

(i) One Year Accelerated Vesting. Immediately prior to the Effective Time, the vesting schedule applicable to each Company Option that is outstanding and unexercised and not vested shall be adjusted so that each vesting date that is scheduled to occur on or after the Effective Time shall accelerate by one year (the “One Year Accelerated Vesting”).

(ii) Vested Company Options. At the Effective Time, each Company Option that is outstanding and unexercised immediately prior to the Effective Time and that is vested as of the Effective Time (after application of the One Year Accelerated Vesting and any vesting acceleration provisions set forth in the terms of such Company Option, if any) (each, a “Vested Company Option”) shall be cancelled and terminated at the Effective Time and the holder thereof shall be entitled, in full satisfaction of the rights of such holder with respect thereto, to receive with respect to each share of Company Common Stock subject to such Company Option an amount in cash equal to the Per Company Option Merger Consideration. Promptly after the Effective Time (and in any event within three (3) Business Days thereafter), Parent shall cause the Surviving Company or its designee to pay to each holder of Vested Company Options a cash amount in immediately available funds equal to the aggregate Per Company Option Closing Payments payable with respect to the Vested Company Options held by such Holder through the payroll system of the Surviving Company. Parent shall, or shall cause the Surviving Company, its designee or the Paying Agent to, deliver the applicable portion of each Future Payment to each such Holder in accordance with Section 5.5(a).

(iii) Unvested Company Options.

(A) At the Effective Time, each Company Option that is outstanding and unexercised immediately prior to the Effective Time and that is not vested as of the Effective Time (after application of the One Year Accelerated Vesting and any vesting acceleration provisions set forth in the terms of such Company Option, if any) (each, an “Unvested Company Option”) shall, automatically and without any action on the part of the holder thereof, cease to represent an option to purchase shares of Company Common Stock and shall be converted into an option to purchase a number of shares of Parent Common Stock equal to the product (rounded down to the nearest whole number) of (x) the number of shares of Company Common Stock subject to such Unvested Company Option immediately prior to the Effective Time and (y) the Option Conversion Ratio, at an exercise price per share (rounded up to the nearest whole cent) equal to (1) the exercise price per share of Company Common Stock of such Unvested Company Option immediately prior to the Effective Time, divided by (2) the Option Conversion Ratio; provided, however, that the exercise price and the number of shares of Parent Common Stock purchasable pursuant to the Unvested Company Options shall be determined in accordance with the foregoing, subject to such adjustments as are necessary in order to satisfy the requirements of Section 409A of the Code; provided, further, that in the case of any Unvested Company Option to which Section 422 of the Code applies, if any, the exercise price and the

number of shares of Parent Common Stock purchasable pursuant to such option shall be determined in accordance with the foregoing, subject to such adjustments as are necessary in order to satisfy the requirements of Section 424(a) of the Code. Except as specifically provided above, following the Effective Time, each Unvested Company Option shall continue to be governed by the same terms (including vesting and exercisability terms) as were applicable to such Unvested Company Option immediately prior to the Effective Time, except to the extent such terms are rendered inoperative by reason of the Merger; provided that each Unvested Company Option shall vest in full on a termination of the Holder’s employment (x) involuntarily by the Holder’s employer without “Cause” (as such term is defined in Section 5.2(a) of the Company Disclosure Letter), (y) voluntarily by the Holder for “Good Reason” (as such term is defined in Section 5.2(a) of the Company Disclosure Letter) or (z) due to the Holder’s death or by the Holder’s employer due to disability, on or after the Effective Time (the “Double Trigger Vesting”).

(B) Following the Effective Time, each holder of an Unvested Company Option (as converted in accordance with Section 5.2(a)(iii)(A)) shall be entitled, subject to such Unvested Company Option vesting, to receive with respect to each share of Company Common Stock subject to such Unvested Company Option an amount in cash equal to (i) each Per Share Milestone Payment, plus (ii) the Per Share Holdback Distribution Amount, plus (iii) each Per Share Escrow Release Amount, in each case in accordance with the terms of this Agreement. If an Unvested Company Option is cancelled or forfeited prior to vesting, then the portion of each of (i) each Per Share Milestone Payment, (ii) the Per Share Holdback Distribution Amount, and (iii) each Per Share Escrow Release Amount that is attributable to such Unvested Company Option will be reallocated among the Holders in accordance with this Agreement.

(iv) Notwithstanding anything to the contrary contained in this Agreement, no payment of any portion of the Per Company Option Merger Consideration will be paid with respect to a Company Option after the later of (x) the fifth (5th) anniversary of the Effective Time and (y) the latest time that payment of such amounts would not result in a tax on the Holder thereof under Section 409A of the Code. Any payment of the Per Company Option Merger Consideration with respect to Company Options that is paid after the later of (x) the fifth (5th) anniversary of the Effective Time and (y) the latest time that payment of such amounts would not result in a tax on the Holder thereof under Section 409A of the Code will be reallocated to holders of Company Shares in accordance with their Pro Rata Share of such amounts (calculated excluding such Company Options).

(b) Exercise of Warrants. The Company shall take or cause to be taken all action necessary to cause, immediately prior to the Effective Time, the exercise of the unexercised portion, if any, of the Warrants in accordance with their respective terms. For the avoidance of doubt, at the Effective Time, each Company Common Share

and share of Series B Preferred Stock issued pursuant to the exercise of the Warrants and outstanding immediately prior to the Effective Time shall be treated as Company Shares in accordance with Section 5.1(a). The Company will comply with that certain agreement listed as Item 10 on Section 6.1(b)(i) (Part A) of the Company Disclosure Letter and such compliance shall be reflected appropriately in the Spreadsheet.

(c) At or prior to the Effective Time, the Company, the board of directors of the Company or any duly authorized committee thereof shall adopt any resolutions and take any corporate or other action necessary to effectuate the provisions of Sections 5.2(a) and 5.2(b).

5.3 Milestone Payments.

(a) If any of the following events shall occur (each a “Milestone”), Parent shall pay, or cause to be paid, pursuant to Section 5.3(f) and Section 5.5, the corresponding milestone payment set forth in this Section 5.3(a) (each a “Milestone Payment”):

worldwide Net Trade Sales for Rova-T equal or exceed [***] in 2021 or any prior calendar year. For Clarity, if the Major Medical Practice Guideline applicable to the United States for SCLC lists preferred products or categorizes products without prioritizing the products within the list of most preferred products or the first category, then a DLL3 Product that is a First Line Therapy and that is included in the most preferred list or in the first category for SCLC under the Major Medical Practice Guideline would be deemed to be equal to or better than the then-current standard of care for the First Line Treatment of SCLC in the United States.

(ii) The first instance on which both of the following are satisfied: (A) the occurrence of a POC Achievement, on or prior to December 31, 2021, with respect to an Alternate Therapeutic Milestone Product directed against a particular molecular target and (B) the determination pursuant to Section 5.3(c) or Section 7.13(b) that the forecast worldwide peak annual Net Trade Sales of such Alternate Therapeutic Milestone Product and all Related Alternate Therapeutic Milestone Products with respect to such first Alternate Therapeutic Milestone Product would equal or exceed $1,000,000,000 (the “First Alternate Therapeutic POC Achievement”).	$	500,000,000

(iii) The first instance on which all of the following are satisfied: (A) the First Alternate Therapeutic POC Achievement has occurred, (B) the occurrence of a POC Achievement, on or prior to December 31, 2021, with respect to an Alternate Therapeutic Milestone Product (other than the First Alternate Therapeutic POC Product) that is directed against a different molecular target than the First Alternate Therapeutic POC Product, and (C) the determination pursuant to Section 5.3(c) or Section 7.13(b) that the forecast worldwide peak annual Net Trade Sales of such Alternate Therapeutic Milestone	$	500,000,000

Product and all Related Alternate Therapeutic Milestone Products with respect to such second Alternate Therapeutic Milestone Product would equal or exceed $1,000,000,000 (the “Second Alternate Therapeutic POC Achievement”).

500,000,000

For the avoidance of doubt, each Milestone Payment in this Section 5.3(a) shall be payable only once upon the first achievement of the applicable Milestone and no amounts shall be due for subsequent or repeated achievement of any Milestone, whether in the same or any subsequent period.

(b) With respect to the Milestone set forth in clause (i) of Section 5.3(a), Parent shall provide written notice to the Stockholder Representative of the achievement of such Milestone no later than ten (10) days after the occurrence thereof and the Milestone Payment corresponding to such Milestone shall be due within thirty (30) days following the occurrence of such achievement.

[***]

If a Milestone Payment is due, such Milestone Payment shall be due within thirty (30) days [***]

Notwithstanding the foregoing, Parent shall not be obligated to deliver an Estimated Forecast Statement with respect to the occurrence of POC Achievement with respect to any Alternate Therapeutic Milestone Product if such Alternate Therapeutic Milestone Product or any Related Alternate Therapeutic Milestone Product with respect thereto has previously triggered the achievement of any of the Milestones in clauses (ii), (iii), (iv) or (v) of Section 5.3(a) and the payment of the corresponding Milestone Payment, respectively.

(d) Notwithstanding anything to the contrary contained in this Agreement, if (1) the Milestones set forth in clauses (ii), (iii), (iv) or (v) of Section 5.3(a) with respect to an Alternate Therapeutic Milestone Product would have been achieved but for the fact that the forecast worldwide peak annual Net Trade Sales of any Alternate Therapeutic Milestone Product and all Related Alternate Therapeutic Milestone Products with respect thereto [***] not to exceed $1,000,000,000 at the time such Milestone would have been triggered, and (2) at any time, whether on, prior to or following December 31, 2022, the actual worldwide peak annual Net Trade Sales of such Alternate Therapeutic Milestone Product and all Related Alternate Therapeutic Milestone Products with respect thereto exceed $1,000,000,000, then the Milestone with respect to such Alternate Therapeutic Milestone Product shall be deemed to have been achieved and the Milestone Payment with respect to such Milestone shall be due within thirty (30) days following the date on which the worldwide peak annual Net Trade Sales exceeded $1,000,000,000.

(e) Each Milestone Payment payable to the Holders (together with any Milestone Interest in respect of late Milestone Payments due and payable in accordance with Section 7.13(b)) shall be delivered by Parent or its designee on each Future Payment Date to the Paying Agent on behalf of and for further distribution to the Holders in accordance with Section 5.5 and the Spreadsheet.

(f) The right of the Holders to receive the Milestone Payments (i) is solely a contractual right and will not be evidenced by a certificate or other instrument, (ii) may not be sold, assigned, transferred, pledged, encumbered or in any other manner transferred or disposed of, in whole or in part, other than through a Permitted Transfer, (iii) does not represent any equity or ownership interest in Parent or in any constituent company to the Mergers or any of their respective Affiliates, and (iv) does not give the Holders any right to receive interest payments (except for Milestone Interest in respect of late Milestone Payments as set forth in Section 7.13(b)).

(g) The right of any Holder to receive any or all Milestone Payments may be waived by such Holder by means of a written waiver instrument (a “Milestone Share Waiver”) executed by such Holder (any such Holder, a “Milestone Waiving Holder”) and delivered to the Stockholder Representative. Additionally, the right of any holder of an Unvested Company Option to receive any Milestone Payment in respect of such Unvested Company Option will be contingent upon, and such Milestone Payments payable in respect of an Unvested Company Option shall be held by the Parent or its designee until, vesting of such Unvested Company Option. On the date on which such Unvested Company Option vests, any previously earned Milestone Payments shall be paid by Parent to, or delivered by Parent to the Surviving Company, its designee or the Paying Agent on behalf of and for further distribution to, the holder of such Unvested Company Option in accordance with Section 5.5 and the Spreadsheet. If an Unvested Company Option is cancelled or forfeited prior to vesting, then the holder thereof (the “Milestone Forfeiting Holder”) will not be entitled to any Milestone Payments in respect of such Unvested Company Option (the “Milestone Option Forfeiture”). Upon the receipt of any Milestone Share Waiver, and in the event of a Milestone Option Forfeiture, the Stockholder Representative shall equitably apportion the Milestone Waiving Holder’s and/or Milestone Forfeiting Holder’s Fully Diluted Share of the Milestone Payments, if any, covered by such Milestone Share Waiver or Milestone Option Forfeiture, as applicable, among all Holders then entitled to a portion of the Milestone Payments, ratably in accordance with their respective Fully Diluted Shares, and the Holder Representative shall amend the Spreadsheet in accordance with Section 5.5(a) to effect such apportionment. Any Milestone Payments held by Parent or its designee on behalf of an Unvested Company Option that is later equitably apportioned in accordance with this Section 5.3(g) shall be paid on the next Future Payment Date in accordance with Section 5.3(e) or, if there is no Future Payment Date, shall be delivered by Parent or its designee as soon as reasonably practicable following the Milestone Option Forfeiture to the Paying Agent on behalf of and for further distribution to the Holders in accordance with Section 5.3 and the Spreadsheet. The Stockholder Representative shall furnish to any Milestone Waiving Holder such documentation as

such Milestone Waiving Holder may reasonably request to evidence such waiver for Tax and accounting purposes.

(h) The Stockholder Representative (on behalf of the Holders) acknowledges and agrees that, notwithstanding anything in this Agreement to the contrary, there is no assurance that any Milestone will be achieved or that the Holders will receive any Milestone Payment. For clarity, this Section 5.3(h) does not constitute a waiver of Parent’s obligations under Section 7.13(d).

On the Closing Date, (i) the Company shall deliver to the Escrow Agent an amount equal to (A) all cash on hand of the Company as of the Closing Date minus (B) the Company Transaction Expenses and (ii) Parent shall pay to the Escrow Agent the Escrow Fund Shortfall Amount, if any. The amounts paid to the Escrow Agent pursuant to this Section 5.4(b) shall be maintained and disbursed as provided in Article IX and the Escrow Agreement. The Escrow Amount shall constitute security for the indemnification obligations provided for in Article IX and shall be held and distributed in accordance with the provisions of this Agreement and the Escrow Agreement.

Parent shall pay all fees and expenses of the Escrow Agent pursuant to the Escrow Agreement.

5.5 Exchange Procedures.

(a) Paying Agent. The Person referred to in Section 5.5(a) of the Company Disclosure Letter, or another nationally recognized paying agent selected by

the Company, shall act as the paying and exchange agent (the “Paying Agent”) in the Merger. Prior to the Closing Date, Parent, the Company and the Stockholder Representative shall enter into an agreement with the Paying Agent (the “Paying Agent Agreement”) which shall have customary terms and shall provide that, (i) on the Closing Date, Parent shall deposit with the Paying Agent, for the benefit of and payment to the Stockholders, the Closing Payment Fund, and (ii) on each Future Payment Date, Parent or the Escrow Agent, as applicable, shall deposit with the Paying Agent, for the benefit of and payment to the Holders, an amount in cash equal to such Future Payment payable to the Holders in accordance with this Agreement, including each Milestone Payment due and payable pursuant to Section 5.3(a), (each such deposit, a “Future Payment Fund” and, together with the Closing Payment Fund, the “Payment Funds”) by wire transfer of immediately available funds to an account specified by the Paying Agent in writing no later than two (2) Business Days prior to each Future Payment Date. The Paying Agent Agreement shall provide that the Payment Funds shall be held and disbursed by the Paying Agent, and Parent shall cause the Paying Agent to hold and disburse the Payment Funds, in accordance with this Section 5.5 and the Spreadsheet. The Paying Agent shall hold the Payment Funds in segregated accounts on behalf of the Holders and use the Closing Payment Fund and each Future Payment Fund for the sole purpose of delivery of the Per Share Closing Consideration to the Stockholders and the delivery of the applicable portion of each Future Payment, if any, to the Holders, respectively, in accordance with the terms of this Agreement. At the election of any Holder who is to receive in excess of $1,000,000 in connection with the transactions by this Section 5.5, the Paying Agent shall make any cash payment in excess of $1,000,000 by wire transfer. Notwithstanding anything to the contrary contained in this Agreement, from and after the Effective Time, the Spreadsheet may be amended by a written statement delivered by the Stockholder Representative to the Paying Agent, Parent and the Surviving Company. Parent, the Surviving Company and the Paying Agent shall cooperate to implement procedures to effect any required withholding of Taxes with respect to any payments specified to be made through the Paying Agent to former holders of Company Options.

(b) Election Procedures. Each Holder of Company Shares as of the date of this Agreement shall have the right, subject to the limitations set forth in this Section 5.5(b), to submit an election with respect to the form of such Stockholder’s Per Share Closing Consideration (each, an “Election”) in accordance with the following procedures:

(i) Promptly following the delivery of the Information Statement to the Holders, the Paying Agent shall mail a form of election (an “Election Form”), such Election Form to be in such form and have such provisions as Parent and the Company reasonably agree, to each Stockholder as of the date of this Agreement.

(ii) Each Stockholder shall specify in its Election Form submitted in accordance with the provisions of this Section 5.5(b) whether such Stockholder elects to receive, with respect to each Company Share held by such Stockholder, (A) the Per Share Standard Election Consideration (such Election, the “Standard Election”), (B) the Per

Share Cash Election Consideration (such Election, the “Cash Election”), or (C) the Per Share Stock Election Consideration (such Election, the “Stock Election”).

(iii) To be effective, an Election Form must be properly completed, duly executed and submitted to the Paying Agent no later than 5:00 P.M. (Eastern Time) on the date that is two (2) Business Days prior to the Closing Date (which date shall be announced by the Company to the Holders as soon as practicable, but in no event less than five (5) Business Days prior to the Closing Date) (the “Election Deadline”). Any Stockholder who does not properly make an Election in accordance with the provisions of this Section 5.5(b), or whose Election Form is not received by the Paying Agent prior to the Election Deadline in the manner provided in this Section 5.5(b)(iii), shall be deemed to have made the Standard Election with respect to its Company Shares.

(iv) Any Stockholder may, at any time prior to the Election Deadline, change or revoke such Stockholder’s Election by written notice received by the Paying Agent prior to the Election Deadline, accompanied by a properly completed and duly executed revised Election Form. Notwithstanding anything to the contrary contained in this Agreement, all Elections shall be automatically deemed to be revoked upon a valid termination of this Agreement in accordance with Article X.

(v) Subject to the terms of this Agreement and the Paying Agent Agreement, the Paying Agent shall have reasonable discretion to determine if any Election is not properly made by a Stockholder with respect to any Company Shares. In the event that the Paying Agent makes the foregoing determination, such Election shall be deemed to be of no force or effect and the Company Shares covered by such Election shall be deemed to have made a Standard Election unless a proper Election is thereafter made with respect to such Company Shares prior to the Election Deadline.

(vi) Promptly after the Effective Time (and in any event within three (3) Business Days thereafter), the Paying Agent shall effect the allocation of the aggregate Per Share Closing Consideration among the Holders of Company Shares (other than Excluded Shares) as set forth in Section 5.1(a), which allocation shall be final, binding and conclusive upon the Stockholders absent manifest error. For the avoidance of doubt, the aggregate amount of cash to be paid and the aggregate number of shares of Parent Common Stock to be issued to the Stockholders in respect of the aggregate Per Share Closing Consideration shall not exceed the aggregate amounts that would have been paid and issued to all Holders of Company Shares (other than Excluded Shares) had the Standard Election been made with respect to all Company Shares.

(vii) Notwithstanding anything to the contrary in this Agreement, but subject to Section 5.5(b)(viii), each Stockholder who is not an Accredited Investor shall be deemed to have made a Cash Election with respect to each Company Share held by such Stockholder and such Company Shares shall not be subject to proration pursuant to this Agreement. Any Stockholder who does not complete, sign and deliver the accredited

investor questionnaire distributed with the Information Statement shall be deemed to be a non-Accredited Investor.

(viii) Notwithstanding anything to the contrary contained in this Agreement, (i) in no event shall the aggregate number of shares of Parent Common Stock to be issued to the holders of Company Shares exceed the number set forth in clause (i) of the definition of “Aggregate Stock Merger Consideration” and (ii) a Stockholder may be deemed to have made a Stock Election or a Standard Election to the extent necessary for the Merger and the Subsequent Merger to qualify for and maintain the tax treatment described in Section 2.4.

(i) Letter of Transmittal. Promptly after the Effective Time (and in any event within three (3) Business Days thereafter), the Paying Agent shall mail to each holder of record of Company Shares as of the Effective Time (other than holders of Excluded Shares): (A) a letter of transmittal in customary form specifying 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 of the Certificates as provided in Section 5.5(f)) to the Paying Agent, such letter of transmittal to be in such form and have such other provisions as Parent and the Company reasonably agree, and (B) instructions for use in effecting the surrender of the Certificates (or affidavits of loss in lieu of the Certificates as provided in Section 5.5(f)) in exchange for the Per Share Closing Consideration and the right to receive the applicable portion of each Future Payment, if any and when due and payable in accordance with the terms and conditions set forth in this Agreement.

(ii) Surrender of Certificates. Upon surrender of a Certificate (or affidavit of loss in lieu of the Certificate as provided in Section 5.5(f)) to the Paying Agent in accordance with the terms of the letter of transmittal, duly executed, the holder of such Certificate shall be entitled to receive in exchange therefor the aggregate Per Share Closing Consideration (including, if applicable, the Fractional Share Cash Amount) and the right to receive the applicable portion of each Future Payment, if any and when due and payable in accordance with the terms and conditions set forth in this Agreement, in each case with respect to the number of Company Shares represented by such Certificate (or affidavit of loss in lieu of the Certificate as provided in Section 5.5(f)), and the Certificate so surrendered shall forthwith be cancelled. No interest will be paid or accrued on any amount payable upon the surrender of any Certificate.

(iii) Future Payments. With respect to each Future Payment, if any and when due and payable in accordance with the terms and conditions set forth in this Agreement, the Paying Agent shall pay to each Holder promptly after each Future Payment Date (and in any event within three (3) Business Days thereafter) a cash amount in immediately available funds equal to the applicable portion of such Future Payment payable to the Holder in accordance with the terms of this Agreement.

(d) Transfers. From and after the Effective Time, there shall be no transfers on the stock transfer books of the Company of the Company Shares or other equity securities of the Company that were outstanding immediately prior to the Effective Time. If, after the Effective Time, any Certificate or other instrument representing Company Shares or other equity securities of the Company is presented to the Surviving Company, Parent or the Paying Agent for transfer, it shall (subject to compliance with the exchange procedures of Section 5.5(b)) be cancelled and exchanged for the amount to which the Holder thereof is entitled pursuant to this Article V. In the event of a transfer of ownership of Company Shares that is not registered in the transfer records of the Company, the aggregate Per Share Closing Consideration to be exchanged upon due surrender of the Certificate or instrument may be issued to such transferee if the Certificate or other instrument formerly representing such Company Shares is properly presented to the Paying Agent, accompanied by all documents reasonably required to evidence and effect such transfer and to reasonably evidence that any applicable stock transfer Taxes have been paid or are not applicable.

(e) Termination of Payment Funds. Any portion of the Closing Payment Fund (including the proceeds of any investments of the Closing Payment Fund) that remains unclaimed by the Stockholders for twelve (12) months after the Effective Time shall be delivered to the Surviving Company. Any portion of a Future Payment Fund (including the proceeds of any reinvestment of such Future Payment Fund) with respect to a Future Payment that remains unclaimed by the Holders for twelve (12) months after the Future Payment Date for each such Future Payment shall be delivered to the Surviving Company. Any holder of Company Shares (other than Excluded Shares) who has not theretofore complied with this Section 5.5 shall thereafter look only to the Surviving Company for payment of the Per Share Closing Consideration and to Parent for the applicable portion of any Future Payments, if any and when due and payable in accordance with the terms and conditions set forth in this Agreement, upon due surrender of its Certificates (or affidavits of loss in lieu of the Certificates), without any interest thereon. Any holder of Company Options who has not theretofore received its applicable portion of Future Payments, if any and when due and payable in accordance with the terms and conditions set forth in this Agreement, in accordance with Section 5.2(a) and this Section 5.5, shall thereafter look only to Parent for payment of such Future Payments. Notwithstanding the foregoing, none of the Surviving Company, Parent, Paying Agent or any other Person shall be liable to any former Holder or holder of Warrants for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar Laws.

(f) Lost, Stolen or Destroyed Certificates. In the event 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 the Paying Agent, the posting by such Person of a bond in customary amount and on such terms as may be reasonably required by the Paying Agent as indemnity against any claim that may be made against it or the Surviving Company with respect to such Certificate, the Paying Agent will issue a check in an aggregate amount equal to (i) the number of

Company Shares represented by such lost, stolen or destroyed Certificate multiplied by the Per Share Closing Consideration, plus (ii) the applicable portion of each Future Payment, if any, then due and payable to such Person in accordance with the terms and conditions set forth in this Agreement.

(g) Appraisal Rights. No Person who properly demands appraisal of such Person’s Company Shares pursuant to Section 262 of the DGCL or, to the extent applicable, Chapter 13 of the CGCL shall be entitled to receive the Per Share Merger Consideration with respect to the Company Shares owned by such Person unless and until such Person shall have effectively withdrawn or otherwise lost such Person’s right to appraisal under the DGCL or CGCL, as applicable. Each Dissenting Stockholder shall be entitled to receive only the payment provided by Section 262 of the DGCL or Chapter 13 of the CGCL, as applicable, with respect to Company Shares owned by such Dissenting Stockholder. If, after the Effective Time, any such holder fails to perfect or effectively withdraws or loses such right, such Excluded Shares shall thereupon be treated as if they had been converted into the right to receive the Per Share Merger Consideration, and the Surviving Company shall remain liable for payment of the Per Share Merger Consideration for such Company Shares; provided that such holder shall be deemed to have made a Cash Election with respect to the Per Share Closing Consideration in accordance with Section 5.5(c). The Company shall give Parent (i) prompt notice of any written demands for appraisal, attempted withdrawals of such demands, and any other instruments served pursuant to applicable Law that are received by the Company relating to stockholders’ rights of appraisal, and (ii) the opportunity to participate in and direct all negotiations and proceedings with respect to demands for appraisal under the DGCL or CGCL. The Company shall not, except with the prior written consent of Parent (such consent not to be unreasonably withheld, conditioned or delayed), voluntarily make any payment with respect to any demands for appraisal, offer to settle or settle any such demands or approve any withdrawal of any such demands.

(h) Withholding Rights. Each of Parent, the Paying Agent, the Surviving Company and the Stockholder Representative shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement, including any Future Payment and any Per Company Option Closing Payment, to any Holder such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code and the rules and regulations thereunder, or any other applicable provision of any Law relating to Taxes. To the extent that amounts are so deducted and withheld, such deducted or withheld amounts (i) shall be remitted by the deducting or withholding Person to the applicable Governmental Entity as required pursuant to applicable Law, and (ii) shall be treated for all purposes of this Agreement as having been paid to the Holders in respect of which such deduction and withholding was made.

(i) No Interest. No interest shall accumulate on any cash or stock payable in connection with the Merger (other than interest accrued on the Escrow Account pursuant to the Escrow Agreement and Milestone Interest in respect of late Milestone Payments as set forth in Section 7.13(c)).

(j) Limitation on Cash Consideration Payable. Notwithstanding anything in this Agreement to the contrary, if the Threshold Percentage (determined, as of the Effective Time, without regard to this sentence) is less than 40.1%, then (x) the amount set forth in clause (i) of the definition of “Aggregate Cash Merger Consideration” shall be deemed reduced by a sufficient amount (the “Cash Reallocation Amount”) and (y) the number of shares of Parent Common Stock set forth in clause (i) of the definition of “Aggregate Stock Merger Consideration” shall be increased by a number of shares equal to the Cash Reallocation Amount divided by the Parent Stock Price, such that the Threshold Percentage, calculated after giving effect to such adjustments will be equal to 40.1%.

5.6 Third Party Beneficiaries. The provisions of this Article V are intended to be for the benefit of, and, following the Effective Time they shall be enforceable against, Parent, Merger Sub I, Merger Sub II and the Surviving Company only by, the Stockholder Representative on behalf of the Holders, who are intended third party beneficiaries thereof. The covenants and obligations of the Stockholder Representative in this Article V are intended to be for the benefit of, and, following the Effective Time may be enforced against, the Stockholder Representative by the Holders, who are intended third party beneficiaries thereof.

In furtherance of and without limiting the generality of the foregoing, each of Parent and the Company shall, as promptly as reasonably practicable, but in no event later than ten (10) Business Days following the execution and delivery of this Agreement (unless a later date is mutually agreed between the Company and Parent), file or cause to be filed with the United States Federal Trade Commission and the United States Department of Justice the notification and report form required for the transactions contemplated by this Agreement pursuant to the HSR Act. Parent and the Company shall request or cause to be requested early termination of the waiting period under the HSR Act in such filings.

connection with, all of the information relating to Parent, the Company or any of their respective Subsidiaries, as the case may be, that appears in any filing made with, or written materials submitted to, any third party and/or any Governmental Entity in connection with the Merger, the Subsequent Merger and the other transactions contemplated by this Agreement. In exercising the foregoing rights, each of the Company and Parent shall act reasonably and as promptly as practicable.

(b) The Company and Parent each shall, upon request by the other, furnish the other with all information concerning itself, its Subsidiaries, directors, officers and stockholders and such other matters as may be reasonably necessary or advisable in connection with any statement, filing, notice or application made by or on behalf of Parent, the Company or any of their respective Subsidiaries to any third party and/or any Governmental Entity in connection with the Merger and the transactions contemplated by this Agreement.

Neither Parent nor the Company shall permit any of its Representatives to participate in any in-person meeting or substantive telephone call or conference with any Governmental Entity in respect of any filing, investigation or other inquiry relating to the transactions contemplated hereby unless it consults with the other party in advance and, to the extent permitted by such Governmental Entity, gives the other party the opportunity to attend and participate thereat.

(d) Subject to the terms and conditions set forth in this Agreement, without limiting the generality of the undertakings pursuant to this Section 7.2, each of the Company and Parent shall provide or cause to be provided to any Governmental Entity with jurisdiction over enforcement of any applicable antitrust or competition Laws (“Government Antitrust Entity”) any non-privileged information and documents requested by such Government Antitrust Entity or that are necessary, proper or advisable to permit consummation of the transactions contemplated by this Agreement.

(e) Promptly following the time of execution and delivery of this Agreement, the Company shall use reasonable best efforts to obtain the Written Consent comprising the Required Stockholder Approval for the adoption of this Agreement by the Stockholders in compliance with the Company’s certificate of incorporation and bylaws and the DGCL and the CGCL. If the Written Consent is duly executed and delivered to the Company, the Company shall promptly deliver to Parent a copy thereof (including by facsimile or other electronic image scan transmission).

waiver of appraisal rights, in a form reasonably satisfactory to Parent and its counsel, from each Stockholder who did not execute the Written Consent.

(h) To the extent any payments made with respect to, or which arise as a result of, this Agreement could be characterized as an “excess parachute payment” within the meaning of Section 280G(b)(1) of the Code, the Company shall (i) within ten (10) Business Days prior to the Closing, disclose to Parent its calculations with respect to the excess parachute payments, along with the assumptions used to make the calculations and the data necessary for Parent to confirm the accuracy of the calculations, (ii) to the extent not already obtained, promptly seek the consent of the recipient of any such payment that would otherwise be due and owing that such payment shall not be due and owing, paid or retained, absent 280G Stockholder Approval (as defined below), and (iii) promptly (and in any case prior to the Effective Time) cause all such payments to be adequately disclosed to, and obtain the vote (whether of approval or disapproval) and use commercially reasonable efforts to have all such payments approved by a vote of, the stockholders of the Company meeting the requirements of the Code and the applicable treasury regulations (“280G Stockholder Approval”). Parent shall have the right to review and comment on any disclosure required by clause (iii) before such disclosure is made. Notwithstanding anything to the contrary contained in Section 5.2, if an excess parachute payment resulting from (x) any accelerated vesting of Company Options, (y) the exercise of a Warrant to purchase Company Common Shares or (z) the lapse of restrictions applicable to any Company Common Shares is waived in accordance with clause (ii) of the first sentence of this Section 7.2(h), and 280G Stockholder Approval of such payment is not obtained, then such accelerated vesting, exercise or lapse of restrictions, as applicable, will not apply. Any Company Option that does not vest as a result of this Section 7.2(h) will be an Unvested Company Option and will be subject to the terms of Section 5.2(a)(iii); provided that such Company Option will not be entitled to the Double Trigger Vesting. Any Warrant to purchase Company Common Shares that is not exercised as a result of this Section 7.2(h) will be converted at the Effective Time into a warrant to purchase Parent Common Stock in accordance with the terms set forth in Section 5.2(a)(iii); provided that such Warrant will not be entitled to the Double

Trigger Vesting. Any Warrant to purchase Company Common Shares that is converted at the Effective Time will be treated for purposes of this Agreement (including for purposes of the Milestone Payments, Holdback Distribution Amount and the Escrow Release Amount) in a manner consistent with an Unvested Company Option. Any Company Common Share that remains subject to restrictions as a result of this Section 7.2(h) will be converted at the Effective Time into a Parent Common Share in accordance with the terms set forth in Section 5.2(a)(iii); provided that such Company Common Share will not be entitled to the Double Trigger Vesting. Any Company Common Share that is converted at the Effective Time will be treated for purposes of this Agreement (including for purposes of the Milestone Payments, the Holdback Distribution Amount and the Escrow Release Amount) in a manner consistent with an Unvested Company Option.

All requests for information made pursuant to this Section 7.3(a) shall be directed to the executive officer or other Person designated by Parent or the Company, as applicable, and neither Parent nor the Company shall directly or indirectly contact any officer, director, employee, agent or representative of the other party or any of its Subsidiaries without the prior approval of such designated Person.

All such information shall be governed by the terms of the Confidentiality Agreement.

(b) For a period of six (6) years following the Closing Date, Parent shall, and shall cause the Surviving Company to, retain all material books, Contracts, documents and records of the Company and its Subsidiary pertaining to all periods prior

(a) Parent agrees that:

(i) during the period commencing at the Effective Time and ending on the second anniversary of the Effective Time, each employee of the Company and its Subsidiary who continues to remain employed with the Company and its Subsidiary at the Effective Time (a “Continuing Employee”) will continue to be provided with base salary or base wage that is no less favorable than the greater of the base salary or base

wage provided by the Company or its Subsidiary, as applicable, to each such Continuing Employee immediately prior to the Effective Time; and

(ii) during the period commencing at the Effective Time and ending on the first anniversary of the Effective Time, each Continuing Employee will continue to be provided with (A) target cash compensation opportunities that are no less favorable than the target cash compensation opportunities provided by the Company or its Subsidiary, as applicable, to each such Continuing Employee immediately prior to the Effective Time, (B) benefits that are no less favorable in the aggregate than the benefits provided by the Company or its Subsidiary, as applicable, to each such Continuing Employee immediately prior to the Effective Time, and (C) severance benefits that are no less favorable than the severance benefits provided to such Continuing Employees immediately prior to the Effective Time. Parent shall, and shall cause the Surviving Company to, honor all employee benefit obligations to current and former employees under the Company Benefit Plans.

(b) Parent will cause any Parent Benefit Plans which the Continuing Employees of the Company and its Subsidiary are entitled to participate in after the Effective Time to take into account for purposes of eligibility to participate, vesting and accrual of paid time off and severance benefits thereunder (except to the extent it would result in a duplication of benefits), service by employees of the Company and its Subsidiary as if such service were with Parent, to the same extent such service was credited under a comparable plan of the Company. Notwithstanding any other statement in this Section 7.5(b) or any other provision of this Agreement, service by employees of the Company and its Subsidiary shall not be considered for purposes of benefit accruals under any defined benefit plan or for purposes of qualifying for subsidized early retirement benefits under any Parent Benefit Plan. In addition, without limiting the generality of the foregoing, Parent shall use commercially reasonable efforts to ensure that: (i) the Continuing Employees are immediately eligible to participate, without any waiting time, in any and all plans providing benefits after the Effective Time to the extent coverage under such plan is intended to replace coverage under a comparable plan in which such Continuing Employees participated immediately before the Effective Time, and (ii) all pre-existing condition exclusions and actively-at-work requirements for purposes of each plan providing medical, dental, pharmaceutical and/or vision benefits are waived for such Continuing Employees and their covered dependents, and that Continuing Employees and their dependents receive credit for expenses incurred under a Company Benefit Plan during the plan year in which the Effective Time occurs for purposes of satisfying any applicable deductible, co-insurance and out-of-pocket requirements under any welfare benefit plans that such Continuing Employees (and, as applicable, their covered dependents) are eligible to participate in after the Effective Time as if such amounts had been paid in accordance with such plans.

(c) Parent shall, and shall cause the Surviving Company to, honor all individual bonus and performance incentive bonus agreements between the Company and each Continuing Employee for the calendar year 2016, as listed on Section 6.1(h) of the

Company Disclosure Letter to the extent that such agreements remain in effect as of the Effective Time. True and complete copies of all agreements listed in Section 6.1(h) of the Company Disclosure Letter, including all amendments, have been made available to Parent.

(d) For purposes of this Section 7.5, compensation and benefits provided by Execustaff HR, Inc. on behalf of the Company shall be treated as provided by the Company.

(e) Notwithstanding the foregoing, nothing contained herein shall (i) be an amendment of any particular Company Benefit Plan, (ii) give any third party any right to enforce the provisions of this Section 7.5 or (iii) prevent Parent, the Surviving Company or any of their Affiliates from (x) amending or terminating any particular benefit plan or (y) terminating the employment of any particular employee.

7.6 Indemnification; Directors’ and Officers’ Insurance.

(a) From and after the Effective Time, Parent shall, and shall cause the Surviving Company to, indemnify and hold harmless, to the fullest extent permitted under applicable Law (and Parent shall also advance expenses as incurred to the fullest extent permitted under applicable Law; provided that the Person to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such Person is not entitled to indemnification), each present and former director and officer of the Company and its Subsidiary (in each case, in their capacities as such) (collectively, the “Company Indemnified Parties”) against any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages or liabilities incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or pertaining to matters existing or occurring at or prior to the Effective Time, including the transactions contemplated by this Agreement.

(b) Any Company Indemnified Party wishing to claim indemnification under Section 7.6(a), upon learning of any such claim, action, suit, proceeding or investigation, shall promptly notify Parent thereof, but the failure to so notify shall not relieve Parent, the Initial Surviving Company or the Surviving Company of any liability it may have to such Company Indemnified Party, except to the extent such failure materially prejudices the indemnifying party. In the event of any such claim, action, suit, proceeding or investigation (whether arising before or after the Effective Time), (i) Parent or the Surviving Company shall have the right to assume the defense thereof and Parent and the Surviving Company shall not be liable to such Company Indemnified Parties for any legal expenses of other counsel or any other expenses subsequently incurred by such Company Indemnified Parties in connection with the defense thereof, except that if Parent or the Surviving Company elects not to assume such defense or counsel for the Company Indemnified Parties advises that there are issues which raise conflicts of interest between Parent or the Surviving Company and the Company

Indemnified Parties, the Company Indemnified Parties may retain counsel satisfactory to them, and Parent or the Surviving Company shall pay all reasonable fees and expenses of such counsel for the Company Indemnified Parties promptly as statements therefor are received; and (ii) the Company Indemnified Parties will cooperate in the defense of any such matter.

(c) For a period of six (6) years following the Effective Time, Parent shall, and shall cause the Surviving Company to, fulfill and honor in all respects the obligations of the Company pursuant to any indemnification agreements between the Company and the Company Indemnified Parties, subject to applicable Law. For a period of six (6) years following the Effective Time, the Governing Documents of the Surviving Company will contain provisions with respect to exculpation, indemnification and advancement of expenses that are at least as favorable to the Company Indemnified Parties as those contained in the certificate of incorporation and bylaws of the Company as in effect on the date hereof, which provisions will not be amended, repealed or otherwise modified in any manner that would adversely affect the rights thereunder of the Company Indemnified Parties. The provisions of such indemnification agreements and Governing Documents shall continue to apply in respect of any claim, action, suit, proceeding or investigation brought against the Company Indemnified Parties within such six (6) year period until the final disposition of any such claim, action, suit, proceeding or investigation.

(d) Prior to the Effective Time, the Company shall and, if the Company is unable to, Parent shall cause the Surviving Company as of the Effective Time to, obtain and fully pay for “tail” insurance policies with a claims period of at least six (6) years from and after the Effective Time from an insurance carrier with the same or better credit rating as the Company’s current insurance carrier with respect to directors’ and officers’ liability insurance (“D&O Insurance”) with benefits and levels of coverage at least as favorable as the Company’s existing policies with respect to matters existing or occurring at or prior to the Effective Time (including in connection with this Agreement or the transactions or actions contemplated hereby); provided, that in no event shall the Company, Parent or the Surviving Company expend for such policies an aggregate premium amount in excess of 300% of the annual premiums currently paid by the Company for such insurance. If the Company and the Surviving Company for any reason fail to obtain such a “tail” insurance policy as of the Effective Time, the Surviving Company shall, and Parent shall cause the Surviving Company to, continue to maintain in effect for a period of at least six (6) years from and after the Effective Time the D&O Insurance in place as of the date of this Agreement with benefits and levels of coverage at least as favorable as those provided in the Company’s existing policies as of the date of this Agreement, or the Surviving Company shall, and Parent shall cause the Surviving Company to, use reasonable best efforts to purchase comparable D&O Insurance for such six (6) year period with benefits and levels of coverage at least as favorable as provided in the Company’s existing policies as of the date of this Agreement; provided, that in no event shall Parent or the Surviving Company be required to expend for such policies an

aggregate premium amount in excess of 300% of the annual premiums currently paid by the Company for such insurance.

(e) If Parent or the Surviving Company or any of their respective successors or assigns (i) shall consolidate with or merge into any other corporation or entity and shall not be the continuing or Surviving Company or entity of such consolidation or merger, or (ii) shall transfer all or substantially all of its properties and assets to any individual, corporation or other entity, then, and in each such case, proper provisions shall be made so that the successors and assigns of Parent or the Surviving Company shall assume all of the obligations set forth in this Section 7.6.

(f) The provisions of this Section 7.6 are intended to be for the benefit of, and shall be enforceable by, each of the Company Indemnified Parties, who are the intended third party beneficiaries hereof.

If any Takeover Statute is or may become applicable to the Merger or the other transactions contemplated by this Agreement, the Company and its board of directors shall grant such approvals and take such actions as are necessary so that such transactions may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise act to eliminate or minimize the effects of such statute or regulation on such transactions.

7.8 Information Statement. As promptly as practicable following the date of this Agreement, the Company and Parent shall prepare and cause to be delivered to all Stockholders a notice and information statement (the “Information Statement”) including, without limitation, (a) a description of the principal terms of this Agreement, the transactions contemplated by this Agreement and the appointment of the Stockholder Representative, (b) a notice, in accordance with Sections 228(e) and 262(d)(2) of the DGCL and Chapter 13 of the CGCL, to all such Persons who did not execute the Written Consent, of their appraisal rights, and (c) the information with respect to the Parent Common Stock comprising the Aggregate Stock Merger Consideration required to comply with the information and disclosure requirements set forth in Rules 502 and 506 of Regulation D promulgated under the Securities Act.

The Company shall provide a draft of the Information Statement and related materials to Parent within a reasonable period of time prior to the dispatch thereof and will consider in good faith any comments proposed by Parent. In connection with the foregoing, the Company shall use commercially reasonable efforts to obtain a confidentiality agreement from each Stockholder with respect to the provisions of this Agreement, in form and substance reasonably satisfactory to Parent and the Company.

Parent shall comply with and take any other action required to be taken under the Securities Act, the Exchange Act, any applicable foreign or state securities or “blue sky” Laws and the rules and regulations thereunder in connection with the issuance of the shares of Parent Common Stock to effect the Merger.

(c) Notwithstanding any other provisions of this Agreement, until the receipt by the Company of the Required Stockholder Approval, if the Company receives an unsolicited bona fide Alternative Proposal that the board of directors of the Company determines in good faith, after consultation with its outside legal counsel and its financial advisors, constitutes or is reasonably likely to result in a Superior Proposal, then the Company may engage in discussions or negotiations with such Person with respect to such Alternative Proposal if the board of directors of the Company determines in good

faith, after consultation with its outside legal counsel, that the failure to do so would be inconsistent with the directors’ fiduciary obligations under Delaware Law. Following the execution and delivery of this Agreement and until the receipt by the Company of the Required Stockholder Approval, the Company shall notify Parent promptly (and in any event within twenty-four (24) hours) after receipt of any Alternative Proposal, any proposals or inquiries that would reasonably be expected to lead to an Alternative Proposal, or any inquiry or request for nonpublic information relating to the Company or its Subsidiary by any Person who has made or would reasonably be expected to make any Alternative Proposal. Subject to the terms of any confidentiality agreement entered into by the Company prior to the date hereof, if any, such notice shall indicate the identity of the Person making the Alternative Proposal, inquiry or request, and the material terms and conditions of any such proposal or offer or the nature of the information requested pursuant to such inquiry or request, including copies of all written requests, proposals or offers, including proposed agreements received by the Company. In connection therewith, (i) the Company shall keep Parent reasonably informed on a prompt and timely basis of the status and material terms (including any amendments or proposed amendments to such material terms) of any such Alternative Proposal or potential Alternative Proposal and keep Parent reasonably informed on a prompt and timely basis as to the nature of any information requested of the Company with respect thereto, and (ii) the Company shall promptly provide to Parent any material nonpublic information concerning the Company provided to any other Person in connection with any Alternative Proposal that was not previously provided to Parent.

(a) Following the Effective Time, Parent shall not, and shall cause its controlled Affiliates, including the Surviving Company, not to, consummate any Change in Control or Carve-Out Transaction unless:

(i) the Person acquiring Parent or acquiring substantially all of its assets with respect to a Change in Control or the Person acquiring the subject Intellectual Property rights, Contracts and/or Parent’s Subsidiaries with respect to a Carve-Out Transaction (each such Person, an “Acquiror”) shall have executed and delivered to the Stockholder Representative a written assumption agreement, in form and substance satisfactory to the Stockholder Representative, expressly assuming the due and punctual payment of any and all Milestone Payments and the performance or observance of every

covenant, duty and obligation of this Agreement on the part of Parent to be performed or observed following the Effective Time; and

(ii) No later than ten (10) Business Days prior to the consummation of any Change in Control or Carve Out Transaction, Parent shall have delivered to the Stockholder Representative a certificate signed by Parent’s chief executive officer or chief financial officer, and a written opinion of outside counsel to Parent, each stating that such Change in Control or Carve-Out Transaction complies with this Section 7.14(a) and that all conditions precedent herein provided for relating to such transaction have been satisfied.

(b) Upon the consummation of any Change in Control or Carve-Out Transaction in accordance with Section 7.14(a), the Acquiror shall succeed to, and be substituted for, and may exercise every right and power of, Parent under this Agreement with the same effect as if such Acquiror had been named as Parent herein, and thereafter, Parent shall be relieved of all obligations and covenants under this Agreement; provided, however, that, in the event that the Acquiror does not have total assets of at least $10,000,000,000 as shown on its most recently prepared audited balance sheet, Parent shall remain liable for the performance by Acquiror of all obligations of Parent hereunder.

7.15 Financing.

(a) Prior to the Closing, the Company shall, and shall cause its Subsidiary to, and shall use its reasonable best efforts to cause its Representatives to, provide all customary cooperation that is reasonably requested by Parent in writing for the arrangement of any third party debt or equity financing for the purpose of financing the Aggregate Cash Merger Consideration and any other amounts required to be paid in connection with the consummation of the transactions contemplated hereby and all related fees and expenses of Parent, Merger Sub I and Merger Sub II (the “Financing”). No action taken by the Company or any of its Representatives under Section 7.15 shall be considered in determining whether a representation, warranty or covenant of the Company hereunder has been breached or whether a condition precedent to the Merger and the Subsequent Merger has been satisfied.

(b) Notwithstanding the provisions of Section 7.15(a) or any other provision of this Agreement to the contrary, nothing in the foregoing Section 7.15(a) will require the Company or its Subsidiary to (i) waive or amend any terms of this Agreement or agree to pay any fees or reimburse any expenses prior to the Closing for which it has not received prior reimbursement or is not otherwise indemnified by or on behalf of Parent, (ii) enter into any definitive agreement prior to the Closing (other than delivery of customary authorization and representation letters in connection with the Financing) or require any director, officer or employee who will not continue in an equivalent position after the closing of the Transaction to execute and deliver any definitive agreement, certificate or other document on behalf of the Company or any of its Subsidiaries, (iii)

give any indemnities that are effective prior to the Closing, (iv) take any action that, in the good faith determination of the Company, would unreasonably interfere with the conduct of the business of the Company and its Subsidiary, (v) provide any information the disclosure of which is prohibited or restricted under applicable Law or that, in the reasonable good faith determination of the Company, is legally privileged, (vi) take any action that will conflict with or violate its organizational documents or any applicable Laws, (vii) take any corporate actions or provide any corporate approvals, (viii) provide in connection with the Financing (A) pro forma financial information, including pro forma cost savings, synergies, capitalization or other pro forma adjustments desired to be incorporated into any pro forma financial information, (B) any description of all or any component of the Financing, including any such description to be included in any liquidity or capital resources disclosure or any “description of notes”, (C) projections, risk factors or other forward-looking statements relating to any component of such financing, (D) subsidiary financial statements or any other information of the type required by Rule 3- 09, Rule 3-10 or Rule 3-16 of Regulation S-X or (E) Compensation Disclosure and Analysis required by Item 402(b) of Regulation S-K, or (ix) require the Company or its Subsidiary or their respective Representatives to furnish any financial statements, audit reports, comfort letters or legal opinions. In addition, no action, liability or obligation of the Company, its Subsidiary or any of their respective Representatives pursuant to any certificate, agreement, arrangement, document or instrument (other than customary authorization and representation letters) relating to the Financing will be effective until the Closing, and neither the Company nor its Subsidiary will be required to take any action pursuant to any certificate, agreement, arrangement, document or instrument (including being an issuer or other obligor with respect to the Financing) that is not contingent on the occurrence of the Closing or that must be effective prior to the Closing (other than customary authorization and representation letters). Nothing in this Agreement will require (x) any Representative of the Company or its Subsidiary to deliver any certificate or opinion or take any other action pursuant to Section 7.15(a) or any other provision of this Agreement that would reasonably be expected to result in personal liability to such officer or Representative or (y) the board of directors of the Company to approve any financing or Contracts related thereto prior to the Closing.

(c) All non-public or other confidential information provided by the Company or any of its Representatives to Parent pursuant to this Agreement will be kept confidential in accordance with the Confidentiality Agreement, except that Parent will be permitted to disclose such information to any financing sources or prospective financing sources that are or may become parties to the Financing (and, in each case, to their respective counsel and auditors) so long as such information is furnished by Parent subject to customary confidentiality undertakings in connection with the Financing.

(d) Parent shall promptly, upon request by the Company, reimburse the Company for all reasonable costs and expenses (including reasonable attorneys’ fees, but excluding the costs of the Company’s preparation of its annual and quarterly financial statements) incurred by the Company or its Subsidiary or their respective Representatives in connection with the Financing, including the cooperation of the Company, its

Subsidiary and their respective Representatives contemplated by Section 7.3(a), and shall indemnify and hold harmless the Company, its Subsidiary and their respective Representatives from and against any and all losses, damages, claims, costs or expenses suffered or incurred by any of them in connection with the arrangement of the Financing and any information used in connection therewith, except with respect to (i) any information provided in writing by the Company or its Subsidiary for use in connection with the Financing, (ii) any matter that would be a breach of any representations and warranties of the Company set forth in Section 6.1 of this Agreement or (iii) any fraud or intentional misrepresentation or willful misconduct by any such persons. Except for the representations and warranties of the Company set forth in Section 6.1 of this Agreement, the Company shall not have any liability to Parent or Merger Sub in respect of any financial statements, other financial information or data or other information provided pursuant to this Section 7.15.

(e) Parent acknowledges and agrees that obtaining the Financing contemplated by this Section 7.15, or any other financing, is not a condition to the Closing, and affirms its obligations to consummate the Transactions irrespective and independently of the availability of any such Financing.

ARTICLE IX

Escrow Fund and Indemnification

9.1 Survival. All representations, warranties and covenants of the Company, Parent, Merger Sub I and Merger Sub II set forth in this Agreement shall survive the consummation of the Merger and continue in full force and effect until the

101

Escrow Termination Date, after which time all such representations, warranties and covenants shall terminate; provided, however, that this Section 9.1 shall not limit any covenant of the parties which by its terms contemplates performance after the Effective Time, including the provisions of this Article IX and Article XI; and provided, further, that if, at any time prior to the Escrow Termination Date, any Indemnified Party, acting in good faith, shall have timely and duly delivered a Claim Notice in accordance with the terms of this Article IX in respect of any such representation and warranty or covenant, then the claim asserted in such Claim Notice and the corresponding representation and warranty or covenant of the Company shall survive the Escrow Termination Date to the extent, and only to the extent, of the claim set forth in such Claim Notice until such time as such claim is finally resolved in accordance with the terms of this Article IX. All other agreements of the Company and Parent contained in this Agreement shall not survive the consummation of the Merger, and shall terminate and be of no further force or effect at the Effective Time. It is the intention of the parties that this Section 9.1 governs the survival periods and termination dates of all representations and warranties contained in this Agreement and, except as otherwise provided herein, supersedes any applicable statutes of limitations that would otherwise apply to such representations and warranties, other than statutes of limitations governing claims under federal and state securities laws.

9.2 Escrow Fund. The amounts to be deposited into escrow pursuant to Section 5.4(b) shall be deposited with an institution selected jointly by Parent and the Stockholder Representative as escrow agent (the “Escrow Agent”), the portion of such deposit up to the Escrow Amount, together with any interest or other amounts that may be earned thereon, to constitute an escrow fund (the “Escrow Fund”) and to be governed by the provisions set forth in this Agreement and in the Escrow Agreement. The Escrow Fund shall be available to fund any payment required by Section 9.7 and, subject to the limitations set forth in this Article IX, shall be available to compensate Parent (on behalf of itself or any other Indemnified Party) for Losses described in Section 9.3(a).

9.3 Indemnification.

(a) Following the Effective Time, and from and only to the extent of the Escrow Fund, Parent and the Surviving Company, their respective Subsidiaries and their and their respective Subsidiaries’ officers and directors (collectively, the “Indemnified Parties”) shall be entitled to be indemnified, defended and held harmless from the Escrow Fund for, from and against any Losses actually suffered, incurred or paid by them to the extent they arise or result from:

(i) the failure of any representation or warranty of the Company set forth in Section 6.1 to be true and correct as of the Effective Time (or, with respect to representations and warranties that by their terms refer to a specific or earlier date, as of such date), it being understood that in determining whether any such representation or warranty failed to be true and correct, such representation and warranty (other than those set forth in the second sentence of Section 6.1(e)(i) (Financial Statements), Section 6.1(e)(iii) (Internal Controls), Section 6.1(f) (Absence of Certain Changes), Section

102

6.1(h)(i) (Company Benefit Plans), clauses (ii) and (ix) of Section 6.1(k) (Company Regulatory Matters), Section 6.1(l)(i) (Company Material Contracts), Section 6.1(p) (Taxes), Section 6.1(q)(viii) (IT Assets) and Section 6.1(w) (Disclosure Matters)) shall be considered without regard to any materiality or Company Material Adverse Effect qualifiers; or

(ii) any failure by the Company to perform any covenant of the Company set forth in this Agreement required to be performed on or prior to the Effective Time; provided, however, that that none of the Indemnified Parties shall be entitled to indemnification under this Article IX if the required performance of any such covenant was waived by Parent prior to the Effective Time.

(b) Notwithstanding anything to the contrary contained in this Agreement, “Losses” shall not include, and there shall not be recoverable from the Escrow Fund, any costs or expenses (including attorneys’ fees or expenses) incurred or paid by any Indemnified Party in connection with any dispute with the Stockholder Representative or any other Person concerning the parties’ respective rights and obligations under this Article IX, which costs and expenses shall be borne by such Indemnified Party.

(c) Notwithstanding anything to the contrary contained in this Agreement, no Indemnified Party shall be entitled to recover any Losses pursuant to Section 9.3(a)(i) (x) with respect to any individual claim or series of related claims arising out of the same facts or circumstances involving Losses contemplated by Section 9.3(a)(i) of less than $250,000 (the “De Minimis Amount”), and (y) unless and until the aggregate amount of the Losses collectively incurred by the Indemnified Parties for which the Indemnified Parties have been finally determined (pursuant to Section 9.7(m)) to be entitled to indemnification pursuant to Section 9.3(a)(i) exceeds an aggregate amount (disregarding any individual claim or series of related claims arising out of the same facts or circumstances lower than the De Minimis Amount) equal to $45,000,000 (the “Deductible Amount”), after which, subject to the limitations set forth in this Article IX, the indemnifying party shall be liable for the amount of any such Losses that are in excess of the Deductible Amount in the aggregate; provided, however, that the foregoing limitations shall not apply to (x) breaches of, or inaccuracies in, the Company Fundamental Representations or the representation and warranty set forth in Section 6.1(e)(iv) or (y) Losses that arise from any intentional fraud committed by or on behalf of the Company or any of its directors, officers, employees or stockholders in the making of any representation or warranty made by the Company in Section 6.1.

(d) Notwithstanding anything to the contrary contained in this Agreement except as provided in Section 9.10 recovery from the Escrow Fund shall serve as the sole and exclusive source of indemnification from which the Indemnified Parties may collect Losses under Section 9.3(a).

103

(e) The right of the Indemnified Parties to indemnification pursuant to this Section 9.3 will not be affected by any investigation conducted or knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing, with respect to any accuracy of any representation or warranty, or performance of or compliance with any covenant or agreement herein.

9.4 Adjustments to Losses.

(a) In calculating the amount of any Loss which an Indemnified Party is entitled to recover pursuant to this Article IX, the proceeds actually received by the Indemnified Party or any of its Affiliates under any insurance policy or pursuant to any claim, recovery, settlement or payment by or against any other Person, net of the present value of any increase in premiums actually imposed by the applicable insurance carrier as a result of the occurrence of the Loss and any other reasonable, actual costs or expenses incurred in connection with securing or obtaining such proceeds.

(b) With respect to any claim brought by an Indemnified Party against any Holder relating to this Agreement and any of the transactions contemplated hereby, each Holder expressly waives any right of subrogation, contribution, advancement, indemnification or other claim against the Company with respect to any amounts owed by such Holder pursuant to this Article IX.

(c) In calculating the amount of any Loss which an Indemnified Party is entitled to recover pursuant to this Article IX, the amount of any accruals or reserves made and specifically referred to in the Financial Statements, in each case, to the extent that the same was not reversed prior to the Closing Date and to the extent such accruals and reserves are related to such Loss, shall be deducted.

(d) If an Indemnified Party recovers an amount from a third party in respect of a Loss that is the subject of indemnification under this Article IX after all or a portion of such Loss has been recovered pursuant to this Article IX, (i) the Indemnified Party shall promptly remit to the Stockholder Representative the excess (if any) of (A) the amount of the Loss recovered from the Escrow Fund, plus (B) the amount received from the third party in respect thereof, less (C) the amount of the relevant Loss and (ii) the Stockholder Representative shall distribute such excess amount to the Holders in accordance with their respective Pro Rata Share.

(e) No Indemnified Parties may recover more than once in respect of any Loss. Notwithstanding anything herein to the contrary, (i) no Indemnified Party shall be entitled to indemnification or reimbursement under any provision of this Agreement for any amount to the extent such Indemnified Party or any of its Affiliates has been indemnified or reimbursed for such amount under any other provision of this Agreement and (ii) no Indemnified Party shall be entitled to indemnification or reimbursement under

104

this Article IX in respect of any component of the Aggregate Merger Consideration, including, for the avoidance of doubt, the Company Transaction Expenses.

(f) No claim for recovery of Losses under this Article IX shall be available to the extent that facts and circumstances that might serve as the basis of such claim would not have arisen but for, or any Loss related thereto was increased by (but only to the extent of such increase), the passing of, or change in, any Law or any change in the interpretation or application of any of the foregoing, following the date of this Agreement.

(g) Notwithstanding anything to the contrary contained in this Agreement, “Losses” shall not include, and there shall not be recoverable under this Article IX, any punitive, indirect or special damages, or any other damages that would not have been reasonably foreseeable to the parties as of the date hereof; provided, however, that nothing in this Section 9.4(g) shall preclude any recovery by an Indemnified Party against an indemnifying party for a Third Party Claim. Furthermore, except for Third Party Claims, the Indemnified Parties shall have no right to make an indemnification claim for any Loss to the extent it is primarily a possible or potential Loss that the Indemnified Parties believe may be suffered, incurred or paid rather than a Loss that has, in fact, been suffered, incurred or paid by the Indemnified Parties.

9.5 Claims.

(a) In the event that any Indemnified Party seeks to assert any claim pursuant to Section 9.3(a), other than a Third Party Claim (a “Direct Claim”), such Indemnified Party shall promptly, but in no event more than thirty (30) calendar days following the Indemnified Party’s receipt of information sufficient for the Indemnified Party to conclude that there has occurred a failure of the type contemplated by Section 9.3(a), provide the Stockholder Representative with a written notice thereof (a “Direct Claim Notice”). Failure of the Indemnified Party to give such notice will not relieve the indemnifying party from its indemnification obligations hereunder, except to the extent that the indemnifying party is actually and materially prejudiced thereby. Each Direct Claim Notice shall describe in reasonable detail the basis asserted by the Indemnified Party for such claim (the “Claim Basis”), specify the amount or the estimated amount, in Dollars, of Losses actually incurred or paid by the Indemnified Party as a result of the Claim Basis, to the extent then ascertainable (the “Claim Amount”), and include all available documentation supporting the Claim Basis and Claim Amount.

(b) In the event that any written claim or demand for which the Escrow Fund may be available to compensate any Indemnified Party under Section 9.3(a) is asserted against any Indemnified Party by a third party (a “Third Party Claim”), such Indemnified Party shall promptly, but in no event more than thirty (30) calendar days following such Indemnified Party’s receipt of such Third Party Claim, provide the Stockholder Representative with a written notice thereof (a “Third Party Claim Notice”); provided, however, that if the Indemnified Party receives a complaint, petition

105

or any other pleading in connection with such Third Party Claim which requires the filing of an answer or other responsive pleading, the Indemnified Party shall provide the Stockholder Representative with the Third Party Claim Notice, together with a copy of such pleading, at least ten (10) calendar days prior to the date a responsive pleading thereto is required to be filed (or promptly upon receipt by the Indemnified Party, if the Indemnified Party receives such complaint, petition or other pleading within such ten (10) calendar day period). Failure of the Indemnified Party to give such notice will not relieve the indemnifying party from its indemnification obligations hereunder, except to the extent that the indemnifying party is actually and materially prejudiced thereby. Each Third Party Claim Notice shall attach a copy of such Third Party Claim, describe in reasonable detail the Claim Basis for such claim, specify the Claim Amount for such Third Party Claim and include all available documentation supporting the Claim Basis and Claim Amount.

(c) The Stockholder Representative shall have thirty (30) calendar days after receipt of each Third Party Claim Notice (the “Defense Determination Period”) to notify the Indemnified Party of its election to defend the Indemnified Party against such Third Party Claim. In the event that the Stockholder Representative notifies the Indemnified Party within the Defense Determination Period of such election, the Stockholder Representative shall have the right to defend the Indemnified Party by appropriate proceedings and shall have the power to direct and control such defense; provided, however, that the Stockholder Representative may not assume control of the defense to a Third Party Claim (i) involving any criminal proceeding, action, indictment, allegation or investigation, or in which relief other than monetary damages is sought; (ii) involving the Company’s Intellectual Property or the alleged misuse, infringement, misappropriation or violation of any third party’s Intellectual Property or (iii) if the Stockholder Representative has not notified the Indemnified Party in writing that the Holders will be liable to indemnify the Indemnified Party with respect to all Losses relating to such Third Party Claim, subject to the limitations of Section 9.3. Once the Stockholder Representative has made such election, (i) the Indemnified Party shall have the right, but not the obligation, to participate in any such defense, at its sole expense (provided, however, that the Indemnified Party shall be entitled to participate in any such defense with separate counsel at the expense of the Holders if (A) so requested by the Stockholder Representative to participate or (B) in the written opinion of outside counsel to the Indemnified Party a conflict or potential conflict exists between the Indemnified Party and the Holders that would make such separate representation advisable; provided, further, that the Holders shall not be required to pay for more than one such counsel for all Indemnified Parties in connection with any Third Party Claim), and (ii) the Stockholder Representative shall not, without the prior written consent of the Indemnified Party, settle such Third Party Claim unless (1) the claimant provides an unqualified release of the Indemnified Parties from all liability in respect of such Third Party Claim, (2) such settlement does not involve any injunctive relief binding upon the Indemnified Parties or any of their Affiliates, (3) such settlement does not encumber any of the material assets of any Indemnified Party or their Affiliates or impose any restriction or condition that would apply to or materially affect any Indemnified Party or the conduct of

106

any Indemnified Party’s business and (4) such settlement does not involve any admission of liability or wrongdoing by any Indemnified Party or any of its Affiliates.

(d) In the event that the Stockholder Representative fails to notify the Indemnified Party prior to the expiration of the Defense Determination Period of its election to defend the Indemnified Party against the Third Party Claim, (i) the Indemnified Party shall assume its own defense, and all reasonable, actual costs and expenses (including reasonable attorneys’ fees and expenses) incurred by such Indemnified Party in connection with such defense shall constitute “Losses” to the extent, but only to the extent, that such Indemnified Party is entitled to indemnification pursuant to this Article IX in respect of such Third Party Claim, and (ii) the Indemnified Party shall not, without the consent of the Stockholder Representative (which consent shall not be unreasonably withheld), settle such Third Party Claim.

9.6 Mitigation. Each Indemnified Party shall use its commercially reasonable efforts to mitigate any Loss which an Indemnified Party is entitled to recover from the Escrow Fund under this Article IX upon acquiring actual knowledge of any event which would be reasonably likely to, or does, give rise to such Loss. In the event an Indemnified Party fails to so use its commercially reasonable efforts to mitigate an indemnifiable Loss in accordance with the preceding sentence, the portion of such Loss that could reasonably have been avoided had the Indemnified Party made the efforts required by this Section 9.6 shall not be recoverable from the Escrow Fund under this Article IX.

9.7 Resolution of Claims.

(a) Each Indemnified Party shall provide to the Escrow Agent a copy of any Direct Claim Notice or Third Party Claim Notice (either, a “Claim Notice”) simultaneously with the delivery thereof to the Stockholder Representative. No Claim Notice shall be provided to the Stockholder Representative or the Escrow Agent following the Escrow Termination Date.

(b) Upon receipt of a Claim Notice in accordance with the terms of this Article IX, the Escrow Agent shall set aside and hold, as a reserve to cover the claim set forth in the Claim Notice (the “Indemnified Party Claim”), a portion of the Escrow Fund equal to the Claim Amount set forth therein (a “Reserve”), until there is a final resolution of such Indemnified Party Claim in accordance with the terms of this Article IX.

(c) Following receipt by the Stockholder Representative and the Escrow Agent of a Claim Notice in accordance with the terms of this Article IX, the Stockholder Representative shall have no fewer than sixty (60) calendar days (the “Claim Investigation Period”) to make an investigation of the Indemnified Party Claim. In connection with each Indemnified Party Claim, Parent and the other Indemnified Parties shall, and shall cause their respective Affiliates and Representatives to, (x) allow the

107

Stockholder Representative and its Representatives to investigate the facts, matters and circumstances alleged to have given rise to such Indemnified Party Claim and the related Claim Basis and Claim Amount, and (y) disclose to the Stockholder Representative and its Representatives all material of which they are aware which relates to the Indemnified Party Claim and promptly provide such information and assistance as the Stockholder Representative and its Representatives shall reasonably request, including reasonable access to premises and personnel (including any employee with knowledge relating to the relevant facts, matters or circumstances or who can otherwise reasonably assist the requesting party), and the right to examine and copy or photograph any relevant assets, accounts, correspondence, documents and records.

(d) At any time prior to the expiration of the Claim Investigation Period, the Stockholder Representative may dispute the Indemnified Party Claim, the related Claim Basis and/or all or any part of the related Claim Amount specified in such Claim Notice (a “Dispute”) by providing written notice of such dispute (a “Dispute Notice”) to Parent and the Escrow Agent on or prior to the expiration of the Claim Investigation Period. Each Dispute Notice shall specify, in reasonable detail, the factual grounds for the Dispute, specify the portion of the Indemnified Party Claim which the Stockholder Representative does not dispute, if any, and include all available documentation supporting such Dispute.

(e) If the Escrow Agent does not receive from the Stockholder Representative a Dispute Notice on or prior to the expiration of the Claim Investigation Period, then the Escrow Agent shall release and distribute to Parent, in accordance with the terms of this Article IX and the Escrow Agreement, no fewer than three (3) Business Days after the expiration of the Claim Investigation Period, such portion of the Escrow Fund equal to the applicable Reserve and, upon payment thereof, such Reserve and such Indemnified Party Claim shall be deemed to have been finally resolved and discharged in full.

(f) If the Escrow Agent receives from the Stockholder Representative, on or prior to the expiration of the Claim Investigation Period, a Dispute Notice, then, to the extent applicable, the Escrow Agent shall release and distribute to Parent a portion of the Escrow Fund equal to the uncontested portion of the Claim Amount, if any, no later than three (3) Business Days after receipt of such Dispute Notice and, upon payment thereof, the relevant portion of the Reserve, Indemnified Party Claim and Dispute shall be deemed to have been finally resolved and discharged in full.

(g) Following the receipt by Parent and the Escrow Agent of a Dispute Notice, if Parent and the Stockholder Representative agree in writing, prior to or on the date of the expiration of the Claim Investigation Period, as to the validity and amount of all or a portion of the Claim Amount of any Indemnified Party Claim that is subject to a Dispute Notice, they shall promptly and jointly provide to the Escrow Agent a written notice (a “Joint Escrow Notice”) directing the Escrow Agent to apply a specified portion of the Escrow Fund in settlement of such Indemnified Party Claim (a “Settlement”), and

108

such Joint Escrow Notice shall contain instructions from Parent as to the delivery of such portion of the Escrow Fund necessary to pay the Settlement; provided, however, for the avoidance of doubt, that the Settlement amount shall in no event include any uncontested portion of the Claim Amount previously released from the Escrow Fund in accordance with Section 9.7(f). The Escrow Agent shall pay the Settlement no later than three (3) Business Days after receipt of such Joint Escrow Notice by the Escrow Agent. Upon payment of the Settlement, the relevant portion of the Reserve, Indemnified Party Claim and Dispute shall be deemed to have been finally resolved and discharged in full. In connection with any Settlement, the Stockholder Representative may also deliver a Dispute Notice in connection with any portion of such Indemnified Party Claim not so settled.

(h) Parent and the Stockholder Representative agree to meet, confer and negotiate in good faith from time to time, each as and when reasonably requested by the other, for a period of thirty (30) calendar days following the date of any Dispute Notice (the “Dispute Negotiation Period”), in order to attempt to resolve the Dispute in its entirety. If Parent and the Stockholder Representative agree, on or prior to the expiration of the Dispute Negotiation Period, as to the validity and amount of all or a portion of any Indemnified Party Claim, they shall promptly and jointly provide to the Escrow Agent a Joint Escrow Notice directing the Escrow Agent to apply a specified portion of the Escrow Fund in resolution of such Dispute (a “Negotiated Resolution”), and such Joint Escrow Notice shall contain instructions from Parent as to the delivery of such portion of the Escrow Fund necessary to pay the Negotiated Resolution and, upon payment thereof, the relevant portion of the Reserve, Indemnified Party Claim and Dispute shall be deemed to have been finally resolved and discharged in full. The Escrow Agent shall pay the Negotiated Resolution no later than three (3) Business Days after receipt of such Joint Escrow Notice by the Escrow Agent.

(i) Promptly following the receipt of a court order or judgment of such court of competent jurisdiction resolving a Dispute, which order or judgment has become a final order from which no appeal has been or can be had (a “Final Judgment”), Parent and the Stockholder Representative shall, by Joint Escrow Notice, direct the Escrow Agent (x) to promptly pay to Parent, out of any remaining portion of the Escrow Fund, if any, the amount of any such Losses incurred by Parent (or any other Indemnified Party) pursuant to such Final Judgment and (y) to release any remaining Reserve in excess of any amount to be paid to Parent pursuant to the immediately preceding clause (x), and upon receipt by the Escrow Agent of the Joint Escrow Notice and payment to Parent of any amount referred to in the preceding clause (x), the relevant Reserve, Indemnified Party Claim and Dispute shall be deemed to have been finally resolved and discharged in full. Any such payment to Parent will be made by the Escrow Agent no later than three (3) Business Days after receipt of such Joint Escrow Notice by the Escrow Agent.

(j) If Parent and the Stockholder Representative agree to a resolution of any Dispute prior to any Final Judgment, Parent and the Stockholder Representative

109

shall, by Joint Escrow Notice, direct the Escrow Agent to make delivery from the Escrow Fund of the amount dictated by such agreement between Parent and the Stockholder Representative, and upon payment thereof, the relevant Reserve, Indemnified Party Claim and Dispute shall be deemed to have been finally resolved and discharged in full. Such payment will be made by the Escrow Agent no later than three (3) Business Days after receipt of such Joint Escrow Notice by the Escrow Agent.

(k) On or as promptly as practicable following the Closing Date (and in any event within five (5) Business Days thereafter), the Escrow Agent shall release and distribute to the Stockholder Representative a portion of the Escrow Fund equal to the amount, if any, by which the amount paid into escrow by the Company pursuant to Section 5.4(b)(i) exceeded the Escrow Amount. Promptly following the Escrow Termination Date (and in any event within five (5) Business Days thereafter), the Escrow Agent shall release and distribute to the Stockholder Representative the balance of the Escrow Fund, less any portion of the Escrow Fund subject to a Reserve. Following the Escrow Termination Date, upon final resolution of any Dispute, the portion of the Escrow Fund subject to a related Reserve shall be released and distributed in accordance with such resolution as set forth in a Joint Escrow Notice or written notice from the Stockholder Representative, as provided in this Article IX.

(l) Any amount released from the Escrow Fund to the Stockholder Representative shall be distributed by the Stockholder Representative to the Holders in accordance with their respective Pro Rata Share. Notwithstanding the foregoing, (1) any Unvested Company Option that is forfeited prior to vesting and prior to the payment of an amount released from the Escrow Fund to the Stockholder Representative shall not be entitled to any portion of any Escrow Release Amount and (2) the right of any holder of an Unvested Company Option that is outstanding and not vested on the date on which an amount is released from the Escrow Fund to the Stockholder Representative to receive a Pro Rata Share of such Escrow Release Amount with respect to such Unvested Company Option will be contingent upon, and such Pro Rata Share of the Escrow Release Amount shall be held by the Stockholder Representative until, vesting of such Unvested Company Option. On the date on which such Unvested Company Option vests, the Stockholder Representative shall pay to the holder of such Unvested Company Option the Pro Rata Share of the Escrow Release Amount in respect of the Unvested Company Option. If such Unvested Company Option is cancelled or forfeited prior to vesting, then the holder thereof will not be entitled to any Escrow Release Amount in respect of such Unvested Company Option (the “Escrow Release Amount Forfeiture”). In the event of an Escrow Release Amount Forfeiture, the portion of the Escrow Release Amount in respect of such Unvested Company Option will be added to the next Milestone Payment that becomes due and payable in accordance with Section 5.3 or, if no Milestone Payment remains, shall be delivered to the Paying Agent on behalf of and for further distribution to the Holders in accordance with Section 5.5.

(m) Any Indemnified Party Claim or any portion thereof, and the liability for and amount of any Losses for which any Indemnified Party is entitled to

110

indemnification pursuant to Section 9.3(a) in respect thereof, shall be deemed to be “finally determined” for purposes of this Article IX: (i) when Parent and the Stockholder Representative have so determined by mutual agreement in a Settlement pursuant to Section 9.7(g), a Negotiated Resolution pursuant to Section 9.7(h) or otherwise, (ii) upon the expiration of the Claim Investigation Period with respect to such Indemnified Party Claim if the Stockholder Representative shall not have delivered a Dispute Notice to the Escrow Agent with respect to such Indemnified Party Claim or a portion thereof, or (iii) when a Final Judgment with respect to such Indemnified Party Claim or portion thereof has been entered into.

9.8 Characterization for Tax Purposes. All payments made out of the Escrow Fund to an Indemnified Party in respect of any indemnification claim pursuant to Section 9.3 shall be treated as adjustments to the Aggregate Merger Consideration for Tax purposes.

9.9 No Set-Off. Notwithstanding anything to the contrary contained in this Agreement, (i) no Indemnified Party shall be entitled to set off, deduct or retain any amount that may be due to such Indemnified Party under this Article IX from any Future Payment, including any Milestone Payment, that becomes due and payable to the Holders in accordance with the terms of this Agreement, and (ii) no Indemnified Party shall be entitled to recover from the Escrow Fund in respect of any claim by such Indemnified Person against any Holder or any other Person for which the Indemnified Party is not entitled to indemnification pursuant to this Article IX.

9.10 Exclusive Remedy. Except as specifically provided in the last sentence of this Section 9.10, the rights and remedies of the Indemnified Parties under this Article IX shall be the sole and exclusive rights, remedies and causes of action for monetary damages which each Indemnified Party may have against the Holders, the Stockholder Representative (in each case, in their capacity as such) and their respective Affiliates and Representatives under, in connection with, arising out of, resulting from or in any way related to this Agreement, the Escrow Agreement, the Merger or any other matter contemplated hereby or thereby, or the process leading up to the execution and delivery of this Agreement and the Escrow Agreement and the Merger, under any theory of recovery whatsoever (including at law or in equity). Without limitation to the generality of, and in connection with and in furtherance of, the foregoing: (i) each of Parent, Merger Sub I, Merger Sub II and, following the Closing, the Surviving Company (on behalf of themselves and each of their Affiliates, which Parent agrees to cause to comply with the provisions of this Section 9.10) expressly waives any and all rights, remedies and causes of action, other than those specified in the immediately preceding sentence, it (or its Affiliates) may have against the Holders, the Stockholder Representative or their respective Affiliates now or in the future under, in connection with, arising out of, resulting from or in any way related to this Agreement, the Escrow Agreement, the Merger or any other matter contemplated hereby or thereby, or the process leading up to the execution and delivery of this Agreement and the Escrow Agreement and the Merger; and (ii) Parent agrees and acknowledges that, following the

111

Closing, the sole remedy for any claim by Parent (or any other Indemnified Party) against the Holders, the Stockholder Representative and their respective Affiliates in respect of this Agreement, shall be an action for damages under, and in accordance with, the terms of this Article IX and all such claims by Parent (or any other Indemnified Party) against the Holders, the Stockholder Representative and their respective Affiliates shall be satisfied solely and exclusively out of the Escrow Fund and shall in no event exceed the Escrow Amount. Each party hereby waives any provision of any Law to the extent that it would limit, restrict, conflict with, or otherwise interfere with the application of, the foregoing agreements. The provisions of this Section 9.10 are intended to be for the benefit of, and following the Effective Time they shall be enforceable by, the Holders, who are intended third party beneficiaries hereof. NOTWITHSTANDING THE FOREGOING AND NOTWITHSTANDING ANY OTHER PROVISION OF THIS AGREEMENT, ABSOLUTELY NOTHING IN THIS AGREEMENT SHALL LIMIT THE RIGHT OF ABBVIE INC. OR ANY OF ITS SUBSIDIARIES OR ANY OTHER INDEMNIFIED PARTY TO SEEK ANY REMEDIES AVAILABLE TO IT UNDER ANY APPLICABLE LAW (I) IN RESPECT OF ANY INTENTIONAL FRAUD COMMITTED BY OR ON BEHALF OF THE COMPANY OR ANY OF ITS DIRECTORS, OFFICERS, EMPLOYEES OR STOCKHOLDERS IN THE MAKING OF ANY REPRESENTATION OR WARRANTY MADE BY THE COMPANY IN THIS AGREEMENT, INCLUDING BUT NOT LIMITED TO THE DISCLOSURE REPRESENTATION OR (II) PURSUANT TO ANY DOCUMENT, INSTRUMENT OR OTHER AGREEMENT THAT IS MADE A PART OF THE ENTIRE AGREEMENT OF THE PARTIES HERETO PURSUANT TO THE FIRST SENTENCE OF SECTION 11.9.

112

(c) by either the Company or Parent if a Governmental Entity shall have issued an order, decree or ruling or taken any other action (including the failure to have taken an action), in any case having the effect of permanently restraining, enjoining or otherwise prohibiting the Merger, which order, decree, ruling or other action is final and non-appealable; provided, however, that the right to terminate this Agreement under this Section 10.1(c) shall not be available to any party whose action or failure to act both constitutes a breach of this Agreement and has been a principal cause of or resulted in the entry, promulgation or occurrence of such order, decree, ruling or other action;

(d) by the Company, upon a breach of any representation, warranty, covenant or agreement on the part of Parent, Merger Sub I or Merger Sub II set forth in this Agreement, or if any representation or warranty of Parent, Merger Sub I or Merger Sub II shall have become untrue, in either case such that the conditions set forth in Section 8.3(a) or 8.3(b) would not be satisfied as of the time of such breach or as of the time such representation or warranty shall have become untrue; provided that the Company may not terminate this Agreement under this Section 10.1(d) prior to thirty (30) days following the receipt of written notice by Parent from the Company of such breach (it being understood that the Company may not terminate this Agreement pursuant to this Section 10.1(d) if the Company is in material breach of this Agreement or if such breach by Parent is cured so that such conditions would then be satisfied);

(g) by the Company, if (i) the Required Stockholder Approval has not yet been received by the Company, and (ii) the board of directors of the Company determines in good faith, after consultation with its outside legal counsel, that the failure to terminate this Agreement would be inconsistent with the directors’ fiduciary obligations under Delaware Law.

(a) The Stockholder Representative (x) shall hold the Stockholder Representative Expenses Holdback Amount in an account segregated from its corporate funds, (y) shall use the Stockholder Representative Expenses Holdback Amount solely for the purposes set forth in this Section 11.4 and not for its operating expenses or any other corporate purposes, and (z) shall not voluntarily make any portion of the Stockholder Representative Expenses Holdback Amount available to its creditors in the event of bankruptcy. The Stockholder Representative shall have the right to recover from the Stockholder Representative Expenses Holdback Amount, prior to any distribution to the Holders, the Stockholder Representative’s reasonable out-of-pocket expenses incurred in the performance of its duties under this Agreement (“Charges”), including, without limitation, costs and expenses resulting from the employment of financial advisors, attorneys, auditors and other advisors and agents assisting in the assessment of arbitration, litigation and settlement of any disputes arising under this Agreement, the Paying Agent Agreement or the Escrow Agreement. Upon final resolution of all liabilities and obligations of the Holders pursuant to the Stockholder Representative Agreements, and full reimbursement of all Charges of the Stockholder Representative as

116

provided herein, the Stockholder Representative shall distribute any remaining portion of the Stockholder Representative Expenses Holdback Amount (the “Holdback Distribution Amount”) to the Holders in accordance with their respective Pro Rata Share; provided that (1) the number of Fully Diluted Shares used for purposes of determining the Pro Rata Share shall not include any Shares underlying any Unvested Company Options that have been forfeited as of the date of such distribution and (2) any Holdback Distribution Amount corresponding to any Excluded Shares or any Company Shares with respect to which the holders thereof have not claimed payment of the Per Share Closing Consideration in accordance with Section 5.5(b) prior to the termination of the Closing Payment Fund pursuant to Section 5.5(e) shall be paid to the Surviving Company. Notwithstanding the foregoing, (A) any Unvested Company Option that is forfeited prior to vesting and prior to the payment of the Holdback Distribution Amount to the Holders shall not be entitled to any portion of the Holdback Distribution Amount and (B) the right of any holder of an Unvested Company Option that is outstanding and not vested on the date on which the Holdback Distribution Amount is paid to the Holders to receive a Pro Rata Share of the Holdback Distribution Amount with respect to such Unvested Company Option will be contingent upon, and such Pro Rata Share of the Holdback Distribution Amount shall be held by the Stockholder Representative until, vesting of such Unvested Company Option. On the date on which such Unvested Company Option vests, the Stockholder Representative shall pay to the holder of such Unvested Company Option the Pro Rata Share of the Holdback Distribution Amount in respect of the Unvested Company Option. If such Unvested Company Option is cancelled or forfeited prior to vesting, then the holder thereof will not be entitled to any Holdback Distribution Amount in respect of such Unvested Company Option (the “Holdback Distribution Amount Forfeiture”). In the event of a Holdback Distribution Amount Forfeiture, the portion of the Holdback Distribution Amount in respect of such Unvested Company Option will be added to the next Milestone Payment that becomes due and payable in accordance with Section 5.3 or, if no Milestone Payment remains, shall be delivered to the Paying Agent on behalf of and for further distribution to the Holders in accordance with Section 5.5.

(b) The Stockholder Representative shall have the right to enforce and protect the rights and interests of the Holders arising out of or in any manner relating to this Agreement and each other agreement, document, instrument or certificate referred to herein or the transactions provided for herein, and to take any and all actions which the Stockholder Representative believes are necessary or appropriate under this Agreement to enforce and protect such rights of the Holders, including asserting or pursuing any claim against Parent or the Surviving Company. Without limiting the generality of the foregoing, the Stockholder Representative shall have the authority to (i) give and receive notices and communications, (ii) negotiate disputes arising under, or relating to, this Agreement or any other agreement, document, instrument or certificate referred to herein or the transactions provided for herein or therein, (iii) execute and deliver such waivers, consents and amendments with respect to any and all matters or issues, including those which may have a negative impact on the Holders, and (iv) settle indemnity or other claims under this Agreement and authorize payment from any escrow account, provided

117

that any amendment to this Agreement that would adversely affect a Holder compared to other Holders shall require the written consent of such Holder. Parent and the Surviving Company shall not have the right to object to, dissent from, protest or otherwise contest the authority or power of the Stockholder Representative to so act in accordance with the terms of this Agreement. The Stockholder Representative shall act as it believes to be in the best interests of the Holders.

(c) With respect to any actions to be taken after the Effective Time pursuant to the terms of this Agreement, the Stockholder Representative will follow the instructions of a majority of the members of an advisory committee of Stockholders (the “Advisory Committee”), which Advisory Committee shall be comprised of the individuals set forth in a written communication to be furnished by the Company to Parent not fewer than three (3) Business Days prior to Closing; provided that (x) if, with respect to any matter, the Advisory Committee does not provide instructions in a timely manner, the Stockholder Representative shall act as it believes to be in the best interests of the Holders, and (y) with respect to any matter which, pursuant to the terms of this Agreement, requires the consent or approval of a specified majority of the Stockholders, the Stockholder Representative and the Advisory Committee will not take action without having obtained such required consent or approval. Except as otherwise decided by the written consent of Stockholders holding, as of immediately prior to the Effective Time, a majority of the Fully Diluted Shares (the “Majority Holders”), the Advisory Committee will have three (3) or more members and, in case of any resignation or vacancy for any other reason, the remaining members of the Advisory Committee will appoint any other Stockholder to fill the vacancy on the Advisory Committee.

(d) At any time after the Effective Time, the Stockholder Representative may resign upon thirty (30) days’ written notice to the Company (prior to the Effective Time), Parent (following the Effective Time) and the Holders, and may be removed for any reason or no reason by the written consent of a majority of the members of the Advisory Committee or the Majority Holders. In the event of the resignation or removal of the Stockholder Representative, a new Stockholder Representative shall be appointed by the written consent of a majority of the members of the Advisory Committee or the Majority Holders. A copy of the written consent appointing such new Stockholder Representative shall be sent to Parent, such appointment to be effective on the later of the date indicated in such written consent or the date a copy of such written consent is received by Parent.

(e) The Stockholder Representative hereby represents and warrants to Parent, Merger Sub I, Merger Sub II and the Company that: (i) the Stockholder Representative is a legal entity, validly existing and, in all material respects, in good standing under the Laws of its jurisdiction of organization, (ii) the Stockholder Representative has all requisite limited liability company power and authority and has taken all limited liability company action necessary in order to execute and deliver this Agreement, the Paying Agent Agreement and the Escrow Agreement and to perform its obligations thereunder, (iii) this Agreement has been, and the Paying Agent Agreement

118

and the Escrow Agreement will be, duly executed and delivered by the Stockholder Representative and, assuming the valid execution and delivery by all counterparties hereto, constitutes or, in the case of the Paying Agent Agreement and the Escrow Agreement, will constitute, a valid and binding obligation of the Stockholder Representative, enforceable against the Stockholder Representative in accordance with its terms, except as enforcement may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar Laws affecting creditors’ rights generally and by general principles of equity (regardless of whether considered in a proceeding in equity or at law), and (iv) the execution, delivery and performance by the Stockholder Representative of this Agreement, the Paying Agent Agreement and the Escrow Agreement does not and will not constitute or result in a breach or violation of, or a default under, the certificate of formation or the bylaws or the limited liability agreement of the Stockholder Representative.

(f) In the event of any pending or threatened action, claim, dispute or other proceeding related to this Agreement, with respect to any information that the Stockholder Representative may share with the Holders, the Stockholder Representative and such Holders will have a commonality of interest with respect thereto and agree that it is their intention and understanding that sharing of information will not waive or diminish the continued protection of the attorney-client privilege, the work product doctrine or any other applicable privilege or doctrine.

(g) The provisions of this Section 11.4 are intended to be for the benefit of, and shall be enforceable by, the Holders, who are intended third party beneficiaries hereof.

11.5 Attorney Client Matters.

(a) Parent agrees to comply with the provisions of this Section 11.5 and, following the Closing, agrees to cause Parent’s controlled Affiliates and Subsidiaries (including, following the Closing, the Company and its Subsidiary) (collectively with Parent, the “Parent Parties”) to comply with the provisions of this Section 11.5 and to execute and deliver any documents or agreements reasonably requested by the Stockholder Representative to implement such provisions.

(b) Notwithstanding any representation of the Company or its Subsidiary by Xxxxxxxx & Xxxxxxxx LLP (“S&C”) prior to the Closing Date, each Parent Party:

(i) consents to S&C’s representation of the Stockholder Representative and/or any Holder (the “Stockholder Parties”) in connection with any matters or disputes arising out of or relating to this Agreement, the Voting Agreement, the Escrow Agreement, the Paying Agent Agreement and the transactions contemplated hereby and thereby;

119

(ii) waives any claim it has or may have that S&C has a conflict of interest or is otherwise prohibited from engaging in such representation based upon S&C’s prior representation of the Company or its Subsidiary; and

(iii) agrees that, if a dispute arises between any Stockholder Party, on the one hand, and any Parent Party, on the other hand, S&C may represent such Stockholder Party notwithstanding that the interests of such Stockholder Party and such Parent Party may be directly adverse and that S&C may have represented the Company or its Subsidiary in a substantially related matter.

(c) As to all communications prior to the Closing that relate in any way to this Agreement, the Voting Agreement, the Escrow Agreement, the Paying Agent Agreement or the transactions contemplated hereby and thereby and that are (x) privileged communications between S&C or another legal advisor, on the one hand, and, prior to the Closing, any Stockholder Party or the Company or its Subsidiary, on the other hand, or (y) communications that refer or relate to such privileged communications (collectively, “Confidential Communications”), each Parent Party agrees that:

(i) the attorney-client privilege belongs, to the extent such privilege exists, to the applicable Stockholder Party, may be controlled by such Stockholder Party and will not pass to or be claimed by any Parent Party. Each Parent Party will not assert that privilege has been waived with respect to Confidential Communications coming into the possession of such Parent Party. To the extent that any Parent Party has or maintains any control of such privilege of such Confidential Communications, such Parent Party will not, except as may be required by applicable Law, waive or attempt to waive such privilege without the prior written consent of the Stockholder Representative. Notwithstanding the foregoing, in the event that, following the Closing, a dispute arises between any Parent Party and a third party (other than a Stockholder Party, but including any Governmental Entity), such Parent Party shall assert the attorney-client privilege against such third party to the extent necessary to prevent disclosure of Confidential Communications.

(ii) Confidential Communications shall be and remain the exclusive property of the Stockholder Parties, notwithstanding that some Confidential Communications may have come into the possession of the Parent Parties.

11.7 GOVERNING LAW; JURISDICTION; WAIVER OF JURY TRIAL.

(a) THIS AGREEMENT SHALL BE DEEMED TO BE MADE IN AND IN ALL RESPECTS SHALL BE GOVERNED BY, INTERPRETED AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF DELAWARE, WITHOUT GIVING EFFECT TO CONFLICTS OF LAWS PRINCIPLES THAT WOULD RESULT IN THE APPLICATION OF THE LAW OF ANY OTHER STATE OR WOULD DIRECT A MATTER TO ANOTHER JURISDICTION. Each of the parties to this Agreement hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of the Court of Chancery of the State of Delaware, or, if (and only if) such court finds it lacks subject matter jurisdiction, the Superior Court of the State of Delaware (Complex Commercial Division) or, if subject matter jurisdiction over the matter that is the subject of the action or proceeding is vested exclusively in the federal courts of the United States of America, the federal court of the United States of America sitting in the district of Delaware, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or the agreements delivered in connection herewith or the transactions contemplated hereby or thereby or for recognition or enforcement of any judgment relating thereto, and each of the parties hereby irrevocably and unconditionally (i) agrees not to commence any such action or proceeding except in the Court of Chancery of the State of Delaware, or, if (and only if) such court finds it lacks subject matter jurisdiction, the Superior Court of the State of Delaware (Complex Commercial Division) or, if subject matter jurisdiction over the matter that is the subject of the action or proceeding is vested exclusively in the federal courts of the United States of America, the federal court of the United States of America sitting in the district of Delaware, as applicable, and any appellate court from any thereof, (ii) agrees that any claim in respect of any such action or proceeding may be heard and determined in the Court of Chancery of the State of Delaware, or, if (and only if) such court finds it lacks subject matter jurisdiction, the Superior Court of the State of Delaware (Complex Commercial Division) or, if subject matter jurisdiction over the matter that is the subject of the action or proceeding is vested exclusively in the federal courts of the United States of America, the federal court of the United States of America sitting in the district of Delaware, as applicable, and any appellate court from any thereof, (iii) 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 such courts and (iv) waives, to the fullest extent permitted by Law, the defense of an inconvenient forum to the maintenance of such action or proceeding in such courts. Each of the parties hereto agrees 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 Law. Each party to this Agreement irrevocably consents to service of process inside or outside the territorial jurisdiction of the courts referred to in this Section 11.7(a) in the manner provided for notices in Section 11.3. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by Law.

121

(b) EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT AND ANY OF THE AGREEMENTS DELIVERED IN CONNECTION HEREWITH OR THE MERGER AND OTHER TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE EITHER OF SUCH WAIVERS, (B) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVERS, (C) IT MAKES SUCH WAIVERS VOLUNTARILY, AND (D) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 11.7(b).

11.8 Specific Performance. The parties hereto hereby agree that irreparable damage would occur in the event that any provision of this Agreement were not performed in accordance with its specific terms or were otherwise breached, and that money damages or other legal remedies would not be an adequate remedy for any such damages. Accordingly, the parties hereto acknowledge and hereby agree that in the event of any breach or threatened breach by the Company, on the one hand, or Parent, Merger Sub I or Merger Sub II, on the other hand, of any of their respective covenants or obligations set forth in this Agreement, the Company, on the one hand, and Parent, Merger Sub I and Merger Sub II, on the other hand, shall be entitled to an injunction or injunctions to prevent or restrain breaches or threatened breaches of this Agreement, by the other(s) (as applicable), and to specifically enforce the terms and provisions of this Agreement to prevent breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of the other(s) (as applicable) under this Agreement. The Company, on the one hand, and Parent, Merger Sub I and Merger Sub II, on the other hand, hereby agree not to raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches or threatened breaches of this Agreement by such party (or parties), and to specifically enforce the terms and provisions of this Agreement to prevent breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of such party (or parties) under this Agreement.

11.9 Entire Agreement.

122

matter hereof, it being understood that the Confidentiality Agreement shall continue in full force and effect until the Closing and shall survive any termination of this Agreement. EACH PARTY HERETO AGREES THAT, EXCEPT FOR THE REPRESENTATIONS AND WARRANTIES CONTAINED IN THIS AGREEMENT OR ANY DOCUMENT, INSTRUMENT OR OTHER AGREEMENT THAT IS MADE A PART OF THE ENTIRE AGREEMENT OF THE PARTIES HERETO PURSUANT TO THE FIRST SENTENCE OF THIS SECTION 11.9, NEITHER PARENT, MERGER SUB I AND MERGER SUB II NOR THE COMPANY MAKES OR RELIES ON ANY OTHER REPRESENTATIONS, WARRANTIES OR INDUCEMENTS, AND EACH HEREBY DISCLAIMS ANY OTHER REPRESENTATIONS, WARRANTIES OR INDUCEMENTS, EXPRESS OR IMPLIED, AS TO THE ACCURACY OR COMPLETENESS OF ANY OTHER INFORMATION, MADE BY, OR MADE AVAILABLE BY, ITSELF OR ANY OF ITS REPRESENTATIVES, WITH RESPECT TO, OR IN CONNECTION WITH, THE NEGOTIATION, EXECUTION OR DELIVERY OF THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY, NOTWITHSTANDING THE DELIVERY OR DISCLOSURE TO THE OTHER OR THE OTHER’S REPRESENTATIVES OF ANY DOCUMENTATION OR OTHER INFORMATION WITH RESPECT TO ANY ONE OR MORE OF THE FOREGOING. No party hereto shall be bound by, or be liable for, any alleged representation, promise, inducement or statement of intention not contained herein.

11.10 No Recourse. Notwithstanding anything that may be expressed or implied to the contrary in this Agreement or in any other document, instrument or other agreement contemplated by or referred to herein or delivered in connection herewith, the parties hereby acknowledge and agree that (a) no Person other than the parties hereto has any obligations under this Agreement; provided that, for the avoidance of doubt, the Stockholder Representative’s obligations under this Agreement are solely with respect to the provisions hereof that apply to the Stockholder Representative, (b) this Agreement may be enforced only against, and any claims, obligations, liabilities or other causes of action (whether at Law, in equity, in contract, in tort or otherwise) based upon, arising out or by reason of, or related in any manner to a breach of this Agreement (including any representation or warranty made in this Agreement), or the negotiation, execution, or performance of this Agreement, may be made only against the parties hereto, and (c) with respect to each party hereto, no current, former or future equity holders, incorporators, controlling persons, directors, officers, employees, agents, Affiliates, members, managers, general or limited partners or Representatives (or any successors, predecessors or assigns of the foregoing) shall have any liability (whether at Law, in equity, in contract, in tort or otherwise) based upon, arising out or by reason of, or related in any manner to, a breach of this Agreement (including any representation or warranty made in this Agreement), or the negotiation, execution, or performance of this Agreement, including any liability in respect of this Agreement that may be granted by statute or based on theories of equity, agency, control, instrumentality, alter ego, domination, sham, single business enterprise, piercing the corporate veil, unfairness, undercapitalization or otherwise; provided, that in no event shall the provisions of this Section 11.10 restrict Parent’s reliance on, and rights with respect to, any express representations or warranties

123

of any Person contained in any document, instrument or other agreement that is made a part of the entire agreement of the parties hereto pursuant to the first sentence of Section 11.9. Notwithstanding anything to the contrary contained in this Agreement or otherwise, no party may seek to rescind this Section 11.10 after the Closing.

11.11 No Third Party Beneficiaries. Except as provided in Section 5.6 (Third Party Beneficiaries), Section 7.6 (Indemnification; Directors’ and Officers’ Insurance), Section 7.11 (Rule 144), Section 9.10 (Exclusive Remedy), Section 11.5 (Attorney Client Matters) and Section 11.10 (No Recourse), Parent and the Company hereby agree that their respective representations, warranties, covenants and agreements set forth herein are solely for the benefit of the other parties hereto, in accordance with and subject to the terms of this Agreement, and this Agreement is not intended to, and does not, confer upon any Person other than the parties hereto any rights or remedies hereunder, including the right to rely upon the representations and warranties set forth herein. The representations and warranties in this Agreement are the product of negotiations among the parties hereto and are for the sole benefit of the parties hereto. Any inaccuracies in such representations and warranties are subject to waiver by the parties hereto in accordance with Section 11.2 without notice or liability to any other Person. In some instances, the representations and warranties in this Agreement may represent an allocation among the parties hereto of risks associated with particular matters regardless of the knowledge of any of the parties hereto. Consequently, Persons other than the parties hereto may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date hereof or as of any other date.

11.12 Obligations of Parent and the Company. Whenever this Agreement requires a Subsidiary of Parent to take any action, such requirement shall be deemed to include an undertaking on the part of Parent to cause such Subsidiary to take such action. Whenever this Agreement requires the Subsidiary of the Company to take any action, such requirement shall be deemed to include an undertaking on the part of the Company to cause its Subsidiary to take such action and, after the Effective Time, on the part of the Surviving Company to cause its Subsidiary to take such action.

11.13 Fees and Expenses. Except as otherwise set forth in this Agreement, all fees and expenses incurred in connection with this Agreement and the transactions contemplated hereby, including fees and expenses of financial advisors, financial sponsors, legal counsel and other advisors, shall be paid by the party incurring such expenses whether or not the Merger is consummated.

11.14 Transfer Taxes. All transfer, documentary, sales, use, stamp, registration and other such Taxes and fees (including penalties and interest) incurred in connection with the Merger and the Subsequent Merger shall be paid by Parent, Merger Sub I and Merger Sub II when due, and Parent, Merger Sub I and Merger Sub II will indemnify the Company and the Holders against liability for any such Taxes.

124

11.15 Severability. The provisions of this Agreement shall be deemed severable and the invalidity or unenforceability of any provision shall not affect the validity or enforceability of the other provisions hereof. If any provision of this Agreement, or the application of such provision to any Person or any circumstance, is invalid or unenforceable, (a) a suitable and equitable provision shall be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision and (b) the remainder of this Agreement and the application of such provision to other Persons or circumstances shall not be affected by such invalidity or unenforceability, nor shall such invalidity or unenforceability affect the validity or enforceability of such provision, or the application of such provision, in any other jurisdiction.

11.16 Assignment. This Agreement shall not be assignable by operation of law or otherwise; provided, however, that Parent may designate, by written notice to the Company, another wholly owned direct or indirect Subsidiary to be a constituent corporation in the Merger or the Subsequent Merger in lieu of Merger Sub I or Merger Sub II, respectively, in which event all references herein to Merger Sub I and/or Merger Sub II shall be deemed references to such other Subsidiary or Subsidiaries, except that all representations and warranties made herein with respect to Merger Sub I and/or Merger Sub II as of the date of this Agreement shall be deemed representations and warranties made with respect to such other Subsidiary or Subsidiaries as of the date of such designation; provided that any such designation shall not materially impede or delay the consummation of the transactions contemplated by this Agreement or otherwise materially impede the rights of the Stockholders of the Company under this Agreement. Any purported assignment in violation of this Agreement is void.
