AGREEMENT AND PLAN OF MERGER

This AGREEMENT AND PLAN OF MERGER (this “Agreement”), dated August 10, 2020, is by and among Ligand Pharmaceuticals Incorporated, a Delaware corporation (“Parent”), Pelican Acquisition Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Parent (“Acquisition Sub”), and Pfenex Inc., a Delaware corporation (the “Company”). Each of Parent, Acquisition Sub and the Company are sometimes referred to as a “Party.” All capitalized terms that are used in this Agreement but not defined in this Agreement shall have the respective meanings ascribed thereto in Annex A.

RECITALS

A. It is proposed that Acquisition Sub shall commence a tender offer (the “Offer”) to acquire all of the outstanding shares of Company Common Stock (other than the Cancelled Company Shares) for (i) $12.00 per share, net to the holder thereof, subject to reduction for any applicable withholding Taxes payable in respect thereof, in cash (such amount, or any different amount per share that may be paid pursuant to the Offer, being hereinafter referred to as the “Cash Portion”), and (ii) the contractual right pursuant to the Contingent Value Rights Agreement in the form attached hereto as Annex C (as it may be amended from time to time, the “CVR Agreement”), to receive a contingent payment upon the achievement of a certain milestone as set forth in the CVR Agreement, without interest (the “CVR Portion”, and together with the Cash Portion, the “Offer Price”), all upon the terms and subject to the conditions set forth in this Agreement;

B. It is also proposed that, as soon as practicable following the consummation of the Offer, Acquisition Sub will merge with and into the Company (the “Merger”) in accordance with the General Corporation Law of the State of Delaware (the “DGCL”) and each share of Company Common Stock that is not tendered and accepted pursuant to the Offer (other than Cancelled Company Shares and Dissenting Company Shares) will thereupon be cancelled and converted into the right to receive cash in an amount equal to the Offer Price, and the Company will survive the Merger as a wholly-owned subsidiary of Parent, all upon the terms and subject to the conditions set forth in this Agreement;

C. The Merger will be governed by Section 251(h) of the DGCL and will be effected as soon as practicable following the consummation of the Offer upon the terms and subject to the conditions set forth in this Agreement;

D. The Company Board has (i) determined that the terms of the Offer, the Merger and the other transactions contemplated by this Agreement are fair to, and in the best interests of, the Company and its stockholders, (ii) determined that it is in the best interests of the Company and its stockholders, and declared it advisable, to enter into this Agreement, (iii) approved the execution and delivery of this Agreement by the Company, the performance by the Company of its covenants and agreements contained in this Agreement and the consummation of the Offer, the Merger and the other transactions contemplated by this Agreement upon the terms and subject to the conditions contained in this Agreement, and (iv) resolved to recommend that the holders of shares of Company Common Stock accept the Offer and tender their shares of Company Common Stock to Acquisition Sub pursuant to the Offer (the “Company Board Recommendation”);

E. The respective boards of directors of each of Parent and Acquisition Sub have (i) determined that the terms of the Offer, the Merger and the other transactions contemplated by this Agreement are fair to, and in the best interests of, Parent and Acquisition Sub, and their respective stockholders, (ii) determined that it is in the best interests of Parent and Acquisition Sub, respectively, and their respective stockholders, and declared it advisable, to enter into this Agreement, and (iii) approved the execution and delivery of this Agreement by Parent and Acquisition Sub, respectively, the performance by Parent and Acquisition Sub, respectively, of their respective covenants and agreements contained in this Agreement and the consummation of the Offer, the Merger and the other transactions contemplated by this Agreement upon the terms and subject to the conditions contained in this Agreement; and

F. Concurrently with the execution and delivery of this Agreement, as a condition and inducement to the willingness of Parent and Acquisition Sub to enter into this Agreement, certain directors and officers of the Company, in their respective capacities as stockholders of the Company, are entering into tender and support Agreements with Parent in substantially the form attached hereto as Annex B (each, a “Support Agreement” and collectively, the “Support Agreements”) pursuant to which the signatories thereto are agreeing to tender their Company Common Stock into the Offer and to take (and refrain from taking) certain other actions in connection with the transactions contemplated by this Agreement, including supporting any actions necessary to consummate the Merger.

AGREEMENT

The Parties therefore agree as follows:

ARTICLE I

THE OFFER

1.1 The Offer.

(a) Offer Commencement. Provided that this Agreement shall not have been terminated pursuant to Article VIII, and subject to the conditions set forth in Section 1.1(b), as promptly as practicable after the date of this Agreement (but in no event more than 15 Business Days thereafter), Acquisition Sub shall (and Parent shall cause Acquisition Sub to) commence (within the meaning of Rule 14d-2 promulgated under the Exchange Act) the Offer to purchase any and all of the shares of Company Common Stock (other than Cancelled Company Shares) at a price per share, subject to the terms of Section 1.1(d), equal to the Offer Price. The Offer shall be made by means of an offer to purchase (the “Offer to Purchase”) that is disseminated to all of the Company Stockholders and contains the terms and conditions set forth in this Agreement, including Section 1.1(b).

(b) Offer Conditions. Notwithstanding any other provisions of the Offer, but subject to compliance with the terms and conditions of this Agreement, in addition to (and not in limitation of) the obligations of Acquisition Sub to extend the Offer pursuant to the terms and conditions of this Agreement, Acquisition Sub shall not be required to accept for payment or, subject to any applicable rules and regulations of the SEC (including Rule 14e-1(c) promulgated under the Exchange Act (relating to the obligation of Acquisition Sub to pay for or return tendered

-2-

shares of Company Common Stock promptly after termination or withdrawal of the Offer)), pay for any shares of Company Common Stock that are validly tendered in the Offer and not withdrawn prior to the expiration of the Offer in the event that, at or prior to the Expiration Time:

(i) there shall not have been validly tendered and not withdrawn in accordance with the terms of the Offer a number of shares of Company Common Stock that, together with the shares of Company Common Stock then owned by Parent and Acquisition Sub (if any), represents at least a majority of all then outstanding shares of Company Common Stock (excluding shares of Company Common Stock tendered pursuant to guaranteed delivery procedures that have not yet been “received,” as such term is defined in Section 251(h) of the DGCL, by the depositary for the Offer pursuant to such procedures) (the “Minimum Condition”);

(ii) any waiting period (and extensions thereof) applicable to the transactions contemplated by this Agreement under the HSR Act shall not have expired or been terminated; or

(iii) any of the following shall have occurred and continue to exist as of immediately prior to Expiration Time:

(A) any Governmental Authority of competent jurisdiction shall have (i) enacted, issued or promulgated any Law that is in effect as of immediately prior to the scheduled expiration of the Offer and has the effect of making the Offer or the Merger illegal or which has the effect of prohibiting or otherwise preventing the consummation of the Offer or the Merger or (ii) issued or granted any Order that is in effect as of immediately prior to the scheduled expiration of the Offer and has the effect of making the Offer or the Merger illegal or which has the effect of prohibiting or otherwise preventing the Offer or the Merger;

(B) (1) any representation or warranty of the Company contained in Section 3.11(a) (Absence of Certain Changes) shall fail to be true and correct in all respects, as of the date of the Agreement and as of the Expiration Time with the same force and effect as if made on and as of such date; (2) any of the representations and warranties set forth in Sections 3.1 (Organization; Good Standing), 3.2 (Corporate Power; Enforceability), 3.3 (Requisite Stockholder Approval), 3.25 (Brokers), 3.26 (Opinion of Financial Advisor) and 3.27 (State Anti-Takeover Statutes) (collectively, the “Fundamental Representations”) shall not be true and correct in all material respects (disregarding any “materiality,” “Company Material Adverse Effect” or other similar qualifications set forth in all such representations or warranties) as of the date of the Agreement and as of the Expiration Time as though made as of the Expiration Time (other than any such representation or warranty that is made only as of a specified date, which need only to be true and correct in all material respects as of such specified date); (3) the representations and warranties set forth in Section 3.6 (Company Capitalization) (the “Capitalization Representation”) shall not be true and correct where the failure to be true and correct would reasonably be expected to result in cost, expense or liability to the Company, Parent and their Affiliates, individually or in the aggregate, of more than $1,250,000) as of the date of the Agreement and as of the Expiration Time, as though made as of the Expiration Time, and (4) any of the representations and warranties of the Company set forth in this Agreement (other than the representations in Section 3.11(a)), the Fundamental Representations or the Capitalization Representation), disregarding any “materiality,” “Company Material Adverse Effect” or other

-3-

similar qualifications set forth in all such representations or warranties, shall not be true and correct in all respects as of the date of the Agreement and as of the Expiration Time, as though made as of the Expiration Time (other than any such representation or warranty that is made only as of a specified date, which need only to be true and correct as of such specified date), except in the case of this clause (4), except where the failure of such representations and warranties not to be true and correct (disregarding any “materiality,” “Company Material Adverse Effect” or other similar qualifications set forth in all such representations or warranties) have not had and would not reasonably be expected have, individually or in the aggregate, a Company Material Adverse Effect;

(C) the Company shall have failed to perform in all material respects the obligations, agreements or covenants that are to be performed or complied with by it under this Agreement at or prior to the Expiration Time;

(D) a Company Material Adverse Effect shall have arisen or occurred following the execution and delivery of this Agreement that is continuing at or prior to the Expiration Time;

(E) this Agreement shall have been properly and validly terminated in accordance with its terms; or

(F) the Company shall not have delivered to Parent a certificate, signed by an executive officer of the Company, certifying that the conditions set forth in clauses (B), (C) and (D) above have been duly satisfied.

(c) Waiving Conditions. Acquisition Sub expressly reserves the right to waive any of the conditions to the Offer and to make any change in the terms of or conditions to the Offer; provided, however, that notwithstanding the foregoing or anything to the contrary set forth in this Agreement, without the prior written consent of the Company, in its sole discretion, Acquisition Sub may not (and Parent shall not permit Acquisition Sub to) (i) waive the Minimum Condition, the condition set forth in Section 1.1(b)(ii) or the condition set forth Section 1.1(b)(iii)(A), or (ii) make any change in the terms of or conditions to the Offer that (A) changes the form of consideration to be paid in the Offer, (B) decreases the Offer Price or the number of shares of Company Common Stock sought in the Offer, other than in the manner required by Section 1.1(d), (C) extends the Offer, other than in a manner required or permitted by the provisions of Section 1.1(e), (D) imposes conditions to the Offer other than those set forth in Section 1.1(b), (E) modifies the conditions set forth in Section 1.1(b) in any manner materially adverse to the holders of shares of Company Common Stock, (F) amends the terms of the CVR Agreement in any manner that is adverse to the holders of shares of Company Common Stock or In-the-Money Company Options, or (G) amends any other term or condition of the Offer in any manner that is materially adverse to the holders of shares of Company Common Stock.

(d) Adjustments to the Offer Price. Subject to the terms of this Agreement, the Offer Price shall be adjusted appropriately to reflect the effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into Company Common Stock), reclassification, combination, exchange of shares or other like change with respect to Company Common Stock occurring on or after the date of this Agreement and prior to the Acceptance Time.

-4-

(e) Expiration and Extension of the Offer.

(i) Unless the Offer is extended pursuant to and in accordance with this Agreement, the Offer shall expire at midnight, New York Time, on the date that is 20 Business Days (for this purpose calculated in accordance with Section 14d-1(g)(3) promulgated under the Exchange Act) after the date the Offer is first commenced (within the meaning of Rule 14d-2 promulgated under the Exchange Act) (as such date and time may be extended, the “Expiration Time”). In the event that the Offer is extended pursuant to and in accordance with this Agreement, then the Offer shall expire on the date and at the time to which the Offer has been so extended.

(ii) Notwithstanding the provisions of Section 1.1(e)(i) or anything to the contrary set forth in this Agreement, unless this Agreement has been terminated in accordance with its terms:

(A) Acquisition Sub shall (and Parent shall cause the Acquisition Sub to) extend the Offer for the minimum period required by any Law or Order, or any rule, regulation, interpretation or position of the SEC or its staff or NYSE American, in any such case which is applicable to the Offer;

(B) in the event that any the conditions to the Offer, other than the Minimum Condition, are not satisfied or waived (if permitted hereunder) as of any then scheduled expiration of the Offer, Acquisition Sub may (and, if requested by the Company, shall) extend the Offer for successive extension periods of up to 10 Business Days each (or any longer period as may be approved in advance by the Company) in order to permit the satisfaction of all of the conditions to the Offer; and

(C) in the event that all of the conditions to the Offer set forth in Section 1.1(b) have been satisfied or waived (if permitted hereunder), except that the Minimum Condition has not been satisfied, as of any then scheduled expiration of the Offer, Acquisition Sub shall extend the Offer for an extension period of ten Business Days (or any longer period as may be approved in advance by the Company), it being understood and agreed that Acquisition Sub shall not be required to extend the Offer pursuant to this clause (C) on more than two occasions, but may, in its sole and absolute discretion, elect to do so;

provided, however, that (1) the foregoing clauses (A), (B) or (C) of this Section 1.1(e)(ii) shall not be deemed to impair, limit or otherwise restrict in any manner the right of the Parties to terminate this Agreement pursuant to the terms of Article VIII, and (2) in no event shall Parent or Acquisition Sub be required to extend the Offer beyond the Termination Date.

(iii) Neither Parent nor Acquisition Sub shall extend the Offer or provide a “subsequent offering period” within the meaning of Rule 14d-11 promulgated under the Exchange Act in any manner other than pursuant to and in accordance with the provisions of Section 1.1(e)(ii) without the prior written consent of the Company.

(iv) Neither Parent nor Acquisition Sub shall terminate or withdraw the Offer prior to the then scheduled expiration of the Offer without the prior written consent of the Company or unless this Agreement is validly terminated in accordance with Article VIII, in which case Acquisition Sub shall (and Parent shall cause Acquisition Sub to) irrevocably and unconditionally terminate the Offer promptly (but in no event more than one Business Day) after such termination of this Agreement.

-5-

(f) Payment for Shares of Company Common Stock. On the terms and subject to satisfaction or waiver by Acquisition Sub of the conditions set forth in this Agreement and the Offer as of the Expiration Time, Acquisition Sub shall (and Parent shall cause Acquisition Sub to) accept for payment, and pay for, all shares of Company Common Stock that are validly tendered and not withdrawn pursuant to the Offer promptly (within the meaning of Section 14e-1(c) promulgated under the Exchange Act) promptly after the Expiration Time (as it may be extended in accordance with Section 1.1(e)(ii)) (such time, the “Acceptance Time”). Without limiting the generality of the foregoing, Parent shall provide or cause to be provided to Acquisition Sub on a timely basis the funds necessary to pay for any shares of Company Common Stock that Acquisition Sub becomes obligated to purchase pursuant to the Offer; provided, however, that without the prior written consent of the Company, Acquisition Sub shall not accept for payment or pay for any shares of Company Common Stock if, as a result, Acquisition Sub would acquire less than the number of shares of Company Common Stock necessary to satisfy the Minimum Condition. The Offer Price payable in respect of each share of Company Common Stock validly tendered and not withdrawn pursuant to the Offer shall be paid net to the holder thereof in cash, subject to reduction for any applicable withholding Taxes payable in respect thereof. The Company shall register the transfer of Company Common Stock accepted for payment effective immediately after the Acceptance Time; provided that Acquisition Sub pays for such Company Common Stock at or immediately after such transfer.

(g) Schedule TO; Offer Documents. As soon as practicable on the date the Offer is first commenced (within the meaning of Rule 14d-2 promulgated under the Exchange Act), Parent and Acquisition Sub shall:

(i) prepare and file with the SEC a Tender Offer Statement on Schedule TO with respect to the Offer (together with all amendments and supplements thereto, and including all exhibits thereto, the “Schedule TO”), which Schedule TO shall contain as an exhibit the Offer to Purchase and forms of the letter of transmittal and summary advertisement, if any, and other customary ancillary documents, in each case, in respect of the Offer (together with all supplements and amendments thereto, the “Offer Documents”);

(ii) deliver a copy of the Schedule TO, including all exhibits thereto, to the Company at its principal executive offices in accordance with Rule 14d-3(a) promulgated under the Exchange Act;

(iii) give telephonic notice of the information required by Rule 14d-3 promulgated under the Exchange Act, and mail by means of first class mail a copy of the Schedule TO, to NYSE American in accordance with Rule 14d-3(a) promulgated under the Exchange Act; and

(iv) cause the Offer Documents to be disseminated to all holders of shares of Company Common Stock as and to the extent required by the Exchange Act.

-6-

Subject to the provisions of Section 6.3, the Offer Documents may include a description of the determinations, approvals and recommendations of the Company Board set forth in Section 1.2(a) and Section 6.3 that relate to the Offer. The Company shall furnish in writing to Parent and Acquisition Sub all information concerning the Company that is required by applicable Law or reasonably requested by Parent or Acquisition Sub to be included in the Offer Documents so as to enable Parent and Acquisition Sub to comply with their obligations under this Section 1.1(g). Parent, Acquisition Sub and the Company shall cooperate in good faith to determine the information regarding the Company that is necessary to include in the Offer Documents in order to satisfy applicable Laws. Each of Parent, Acquisition Sub and the Company shall promptly correct any information provided by it or any of its respective directors, officers, employees, affiliates, agents or other representatives for use in the Offer Documents if and to the extent that such information shall have become false or misleading in any material respect.

(i) Company Common Stock.

(ii) Excluded Company Common Stock. Each share of Company Common Stock owned by Parent, Acquisition Sub or the Company, or by any wholly-owned Subsidiary of Parent or Acquisition Sub, in each case immediately prior to the commencement of the Offer (“Cancelled Company Shares”), irrevocably accepted for purchase pursuant to the Offer (“Accepted Company Shares”) shall be cancelled and extinguished without any conversion thereof or consideration paid therefor.

-11-

(iii) Capital Stock of Acquisition Sub. Each share of common stock, par value $0.001 per share, of Acquisition Sub that is outstanding immediately prior to the Effective Time shall be converted into one validly issued, fully paid and nonassessable share of common stock of the Surviving Corporation. Each certificate evidencing ownership of such shares of common stock of Acquisition Sub shall thereafter evidence ownership of shares of common stock of the Surviving Corporation.

(b) Adjustment to the Merger Consideration. Subject to the terms of this Agreement, the Merger Consideration shall be adjusted appropriately to reflect the effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into Company Common Stock but excluding, for the avoidance of doubt, the granting or other issuance of Company Options in the ordinary course of business), reclassification, combination, exchange of shares or other like change with respect to Company Common Stock occurring on or after the date hereof and prior to the Effective Time.

(i) Notwithstanding anything to the contrary set forth in this Agreement, all shares of Company Common Stock that are issued and outstanding immediately prior to the Effective Time and held by Company Stockholders who shall neither have voted in favor of the Merger nor consented thereto in writing and who shall have properly and validly perfected their statutory rights of appraisal in respect of such shares of Company Common Stock in accordance with Section 262 of the DGCL (collectively, “Dissenting Company Shares”) shall not be converted into, or represent the right to receive, the Merger Consideration pursuant to Section 2.7(a), but shall be entitled only to such rights as are granted by the DGCL to a holder of Dissenting Company Shares. At the Effective Time, the Dissenting Company Shares shall no longer be outstanding and shall automatically be cancelled and cease to exist, and each Company Stockholder who holds Dissenting Company Shares shall cease to have any rights with respect thereto, except the right to receive payment of the appraised value of such Dissenting Company Shares in accordance with the provisions of Section 262 of the DGCL; provided, however, that all Dissenting Company Shares held by Company Stockholders who shall have failed to perfect or who shall have effectively withdrawn or lost their rights to appraisal of such Dissenting Company Shares under such Section 262 of the DGCL shall no longer be considered to be Dissenting Company Shares and shall thereupon be deemed to have been converted into, and to have become exchangeable for, as of the Effective Time, the right to receive the Merger Consideration, without interest thereon, upon surrender of the certificate or certificates that formerly evidenced such shares of Company Common Stock in the manner provided in Section 2.8.

(ii) The Company shall give Parent (A) prompt notice of any demands for appraisal received by the Company, withdrawals of such demands, and any other instruments served pursuant to Delaware Law and received by the Company in respect of Dissenting Company Shares and (B) the opportunity to be consulted on all negotiations and proceedings with respect to demands for appraisal under Delaware Law in respect of Dissenting Company Shares.

(d) Company Options.

(i) Upon the terms and subject to the conditions set forth in this Agreement, effective as of immediately prior to the Effective Time, by virtue of the Merger and without any action on the part of Parent, Acquisition Sub, the Company, or the holders thereof, each Company Option that is outstanding and unexercised immediately prior to the Effective Time, shall be accelerated in full.

(ii) Effective as of immediately prior to the Effective Time, by virtue of the Merger and without any action on the part of Parent, Acquisition Sub, the Company, or the holders thereof, each In-The-Money Company Option that remains outstanding and unexercised as of immediately prior to the Effective Time shall be cancelled and extinguished and be converted automatically into the right to receive, with respect to each share of Company Common Stock subject to such In-The-Money Company Option, upon the terms of this Agreement, an amount in cash, without interest, equal to (A) the excess, if any, of (1) the Cash Portion over (2) the per share exercise price of such In-The-Money Company Option, plus (B) the CVR Portion (collectively, the “Option Consideration”), subject, in each case, to applicable Tax withholdings. The CVR Portion in respect of each In-The-Money Company Option shall be subject to the same terms and conditions as applicable to the CVR Portion in respect of Company Common Stock generally.

(iii) Parent shall cause the Surviving Corporation to pay to the former holder of each such cancelled In-The-Money Company Option, in accordance with its normal payroll processes, as promptly as practicable (and in no event later than the first payroll date of the Surviving Corporation after the Effective Time), the foregoing payments to which such holder is entitled pursuant to this Section 2.7(d). For the avoidance of doubt, with respect to any Out-of-The Money Company Option, by virtue of the occurrence of the Effective Time and without any action on the part of Parent, Acquisition Sub, the Company, the Surviving Corporation or the holders thereof, such Out-of-The Money Company Option will automatically terminate and be canceled without payment of any consideration to the holder thereof (and, for the avoidance of doubt, shall also not be eligible to receive the CVR Portion).

(iv) The Company shall send a written notice in a form provided in advance, and reasonably acceptable to Parent, to each holder of an outstanding Company Option in accordance with the Company Stock Plans that shall inform such holder of the treatment of the Company Options, as applicable, provided in this Section 2.7.

(e) Employee Stock Purchase Plan. Effective as of no later than immediately preceding the Effective Time, the Company shall have terminated the Company ESPP. Prior to the Effective Time, the Company Board (or, if appropriate, any committee administering the Company’s ESPP) shall adopt such resolutions with respect to the Company ESPP to provide that (i) all outstanding purchase rights under the Company ESPP shall automatically be exercised, in accordance with the terms of the Company ESPP, no later than one Business Day prior to the Effective Time (the “Final Purchase”), (ii) the Company ESPP shall terminate with such purchase and no further purchase rights will be granted under the Company ESPP thereafter, (iii) each individual participating in the Company ESPP shall not be permitted (x) to increase the amount of his or her rate of payroll contributions thereunder from the rate in effect on the date of this Agreement, or (y) to make separate non-payroll contributions to the Company ESPP on or

-13-

following the date of this Agreement, (iv) no individual who is not participating in the Company ESPP as of the date of this Agreement may commence participation in the Company ESPP following the date of this Agreement, and (v) the Administrator (as defined in the Company ESPP) will notify each participant in writing or electronically prior to the Final Purchase, that the exercise date for the participant’s option has been changed to the date of the Final Purchase and that the Participant’s option will be exercised automatically on the date of the Final Purchase. All shares of Company Common Stock purchased in the Final Purchase shall be cancelled at the Effective Time and converted into the right to receive the Merger Consideration in accordance with the terms and conditions of this Agreement.

(f) Implementation. As soon as reasonably practicable following the date hereof, and in any event prior to the Expiration Time, the Company Board or a committee thereof shall adopt resolutions and use its commercially reasonable efforts to take such other actions as may be required to effectuate the transactions contemplated by Sections 2.7(d) and 2.7(e) under the Company Stock Plans, all Company Option agreements, the Company ESPP, and any other plan or arrangement of the Company.

2.8 Exchange of Certificates.

(a) Payment Agent. Prior to the Acceptance Time, Parent shall, at its sole cost and expense, (i) select a bank or trust company reasonably acceptable to the Company to act as the payment agent for the Merger (the “Payment Agent”) and to act as rights agent (in such capacity, the “Rights Agent”) under the CVR Agreement and (ii) enter into a payment and rights agent agreement, in form and substance reasonably acceptable to the Company, with such Payment Agent and Rights Agent.

(b) Exchange Fund. At or prior to the Closing, Parent shall deposit (or cause to be deposited) with the Payment Agent, by wire transfer of immediately available funds, for payment to the holders of shares of Company Common Stock pursuant to the provisions of this Article II, an amount of cash equal to the aggregate consideration to which such holders of Company Common Stock become entitled under this Article II (which, for the avoidance of doubt, shall not include the Option Consideration). Until disbursed in accordance with the terms and conditions of this Agreement, such cash shall be invested by the Payment Agent, as directed by Parent or the Surviving Corporation, in obligations of or guaranteed by the United States of America or obligations of any agency or instrumentality of the United States of America and backed by the full faith and credit of the United States of America with a maturity of no more than 30 days (such cash amount being referred to in this Agreement as the “Exchange Fund”) provided that Parent shall not be required to deposit the funds related to the CVR Portion with the Rights Agent unless and until such deposit is required pursuant to the terms of the CVR Agreement. Any interest and other income resulting from such investments of the Exchange Fund shall be paid to Parent or the Surviving Corporation, as Parent directs. To the extent that (A) there are any losses with respect to any investments of the Exchange Fund; (B) the Exchange Fund diminishes for any reason below the level required for the Payment Agent to promptly pay the cash amounts contemplated by this Article II, or (C) all or any portion of the Exchange Fund is unavailable for Parent (or the Payment Agent on behalf of Parent) to promptly pay the cash amounts contemplated by this Article II for any reason, then Parent shall, or shall cause the Surviving Corporation to, promptly replace or restore the amount of cash in the Exchange Fund so as to ensure that the Exchange Fund is at all times fully available for distribution and maintained at a level sufficient for the Payment Agent to make such payments contemplated by this Article II.

-14-

(c) Payment Procedures. Promptly following the Effective Time (and in any event within three Business Days), Parent and the Surviving Corporation shall cause the Payment Agent to mail to each holder of record (as of immediately prior to the Effective Time) of (i) a certificate or certificates which immediately prior to the Effective Time represented outstanding shares of Company Common Stock (the “Certificates”) and (ii) book-entry security entitlements to or other uncertificated shares of Company Common Stock (the “Uncertificated Shares”), in each case, whose shares were converted into the right to receive the Merger Consideration pursuant to Section 2.7 (A) a letter of transmittal in customary form (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Payment Agent), and/or (B) instructions for use in effecting the surrender of the Certificates and Uncertificated Shares in exchange for the Merger Consideration payable in respect thereof pursuant to the provisions of this Article II. Upon surrender of Certificates for cancellation to the Payment Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, the holders of such Certificates shall be entitled to receive in exchange therefor an amount in cash equal to the product obtained by multiplying (x) the aggregate number of shares of Company Common Stock represented by such Certificate that were converted into the right to receive the Merger Consideration pursuant to Section 2.7, by (y) the Merger Consideration (less any applicable withholding Taxes payable in respect thereof), and the Certificates so surrendered shall forthwith be canceled. Upon receipt of an “agent’s message” by the Payment Agent (or such other evidence, if any, of transfer as the Payment Agent may reasonably request) in the case of a book-entry transfer of Uncertificated Shares, the holders of such Uncertificated Shares shall be entitled to receive in exchange therefor an amount in cash equal to the product obtained by multiplying (x) the aggregate number of shares of Company Common Stock represented by such holder’s transferred Uncertificated Shares that were converted into the right to receive the Merger Consideration pursuant to Section 2.7, by (y) the Merger Consideration (less any applicable withholding Taxes payable in respect thereof), and the transferred Uncertificated Shares so surrendered shall forthwith be canceled. The Payment Agent shall accept such Certificates and transferred Uncertificated Shares upon compliance with such reasonable terms and conditions as the Payment Agent may impose to effect an orderly exchange thereof in accordance with normal exchange practices. No interest shall be paid or accrued for the benefit of holders of the Certificates and Uncertificated Shares on the Merger Consideration payable upon the surrender of such Certificates and Uncertificated Shares pursuant to this Section 2.8. Until so surrendered, outstanding Certificates and Uncertificated Shares shall be deemed from and after the Effective Time, to evidence only the right to receive the Merger Consideration, without interest thereon, payable in respect thereof pursuant to the provisions of this Article II.

(d) Transfers of Ownership. In the event that a transfer of ownership of shares of Company Common Stock is not registered in the stock transfer books or ledger of the Company, or if the Merger Consideration is to be paid in a name other than that in which the Certificates or Uncertificated Shares surrendered in exchange therefor are registered in the stock transfer books or ledger of the Company, the Merger Consideration may be paid to a Person other than the Person in whose name the Certificate or Uncertificated Share so surrendered is registered in the stock transfer books or ledger of the Company only if such Certificate or Uncertificated Shares is

-15-

properly endorsed and otherwise in proper form for surrender and transfer and the Person requesting such payment has paid to Parent (or any agent designated by Parent) any transfer Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of such Certificate or Uncertificated Shares, and established to the satisfaction of Parent (or any agent designated by Parent) that such transfer Taxes have been paid or are otherwise not payable.

(e) Required Withholding. Each of the Payment Agent, the Rights Agent, Parent, Acquisition Sub, any Affiliate of Parent, and the Surviving Corporation shall be entitled to deduct and withhold from any amounts payable pursuant to this Agreement and pay to the applicable Taxing Authority such amounts that each of the Payment Agent, the Rights Agent, Parent, Acquisition Sub, any Affiliate of Parent, or the Surviving Corporation is required to deduct or withhold with respect to the making of such payment under the Code or any other provision of applicable Tax Laws. To the extent that such amounts are so deducted and withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person in respect of whom such deduction and withholding was made.

(f) No Liability. Notwithstanding anything to the contrary set forth in this Agreement, none of the Payment Agent, Parent, Acquisition Sub, the Surviving Corporation nor any other Party shall be liable to a holder of shares of Company Common Stock in respect of any amounts that would otherwise have been payable in respect of any Certificates or Uncertificated Shares from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.

(g) Distribution of Exchange Fund to Parent. Any portion of the Exchange Fund (including any interest or other amounts earned with respect thereto) that remains undistributed to the holders of the Certificates or Uncertificated Shares on the date that is nine months after the Effective Time shall be delivered to Parent upon demand, and any holders of shares of Company Common Stock that were issued and outstanding immediately prior to the Merger who have not theretofore surrendered their Certificates or Uncertificated Shares representing such shares of Company Common Stock that were issued and outstanding immediately prior to the Merger for exchange pursuant to the provisions of this Section 2.8 shall thereafter look for payment of the Merger Consideration payable in respect of the shares of Company Common Stock represented by such Certificates or Uncertificated Shares solely to Parent, as general creditors thereof, for any claim to the applicable Merger Consideration to which such holders may be entitled pursuant to the provisions of this Article II.

2.9 No Further Ownership Rights in Company Common Stock. From and after the Effective Time, all shares of Company Common Stock shall no longer be outstanding and shall automatically be cancelled, retired and cease to exist, and each holder of a Certificate or Uncertificated Shares theretofore representing any shares of Company Common Stock shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration payable therefor upon the surrender thereof in accordance with the provisions of Section 2.8. The Merger Consideration paid in accordance with the terms of this Article II shall be deemed to have been paid in full satisfaction of all rights pertaining to such shares of the Company Common Stock. At the Effective Time, the stock transfer books of the Surviving Corporation shall be closed, and thereafter there shall be no further registration of transfers on the records of the Surviving

-16-

Corporation of shares of Company Common Stock that were issued and outstanding immediately prior to the Effective Time, other than transfers to reflect, in accordance with customary settlement procedures, trades effected prior to the Effective Time. If, after the Effective Time, Certificates or Uncertificated Shares are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article II. The Company shall take all actions necessary to ensure that, from and after the Effective Time, neither Parent nor the Surviving Corporation shall be required to deliver shares of Company Common Stock or other capital stock of the Company, Parent or the Surviving Corporation to any Person as a result of the exercise of or in settlement of Company Options, and that such Company Options shall be cancelled and the holders of such Company Options shall only be entitled to receive the consideration, if any, provided to them under Section 2.7 and shall not have any other rights or remedies with respect thereto.

2.10 Lost, Stolen or Destroyed Certificates. In the event that any Certificates shall have been lost, stolen or destroyed, the Payment Agent shall issue in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof (in form and substance reasonably satisfactory to the Surviving Corporation), the Merger Consideration payable in respect thereof pursuant to Section 2.7; provided that Parent or the Payment Agent may, in its discretion and as condition to the payment of such Merger Consideration, require the owners of such lost, stolen or destroyed Certificates to deliver a bond in such customary amount as it may direct as indemnity against any claim that may be made against Parent, the Surviving Corporation or the Payment Agent with respect to the Certificates alleged to have been lost, stolen or destroyed.

2.11 Necessary Further Actions. If, at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Surviving Corporation with full right, title and possession to all assets, property, rights, privileges, powers and franchises of the Company and Acquisition Sub, the directors and officers of the Company and Acquisition Sub shall take all such lawful and necessary action.

(ii) there occurs an Intervening Event which is continuing, the Company Board may effect a Company Board Recommendation Change if and only if: (A) the Company Board and/or any authorized committee thereof shall have determined in good faith (after consultation with outside legal counsel) that the failure to make a Company Board Recommendation Change in light of such Intervening Event would be inconsistent with its fiduciary duties; (B) the Company shall have notified Parent in writing at least four Business Days prior to effecting such Company Board Recommendation Change which notice shall (i) expressly state that an Intervening Event has occurred and is continuing, (ii) include a reasonable description of such Intervening Event, and (iii) state that the Company intends to effect a Company Board Recommendation Change (an “Intervening Event Notice”) (it being agreed that the delivery of the Intervening Event Notice shall not in and of itself be deemed a Company Board Recommendation Change for purposes of this Agreement); (C) the Company shall have made its Representatives available to discuss with Parent’s Representatives (if requested by Parent) any proposed modifications to the terms and conditions of this Agreement during the period beginning at 5:00 p.m. Pacific Time on the day of delivery by the Company to Parent of such Intervening Event Notice and ending at 5:00 p.m. Pacific Time on the fourth Business Day following the day of such delivery; and (D) if Parent shall have delivered to the Company during such five Business Day period a written and binding offer to modify the terms of this Agreement (which is set forth in a definitive written amendment to this Agreement executed by Parent and Acquisition Sub and delivered to the Company), the Company Board and/or any authorized committee thereof shall have determined in good faith, after considering the terms of such offer by Parent, that the failure to make a Company Board Recommendation Change in light of such Intervening Event would still be inconsistent with its fiduciary duties.

(iii) For the avoidance of doubt, notwithstanding anything in this Section 6.3(a) to the contrary, the Company Board may not effect a Company Board Recommendation Change or terminate this Agreement pursuant to Section 8.1(e) until the expiration or waiver of the applicable notice period set forth in clauses (i) and (ii) above, and unless and until the Company Board concludes in good faith, after considering any proposed offer to modify the terms of the Agreement from Parent (if any) and consultation with outside legal counsel, that the failure to effect a Company Board Recommendation Change or terminate this Agreement pursuant to Section 8.1(e) would still be inconsistent with its fiduciary duties under applicable Law.

-60-

prohibit access to any documents or information to the extent that, in the reasonable good faith judgment of the Company, (i) any applicable Law requires the Company to restrict or otherwise prohibit access to such documents or information, or (ii) access to such documents or information would give rise to a material risk of waiving any attorney-client privilege, work product doctrine or other applicable privilege applicable to such documents or information; and provided further, however, that no information or knowledge obtained by Parent in any investigation conducted pursuant to the access contemplated by this Section 6.6 shall affect or be deemed to modify any representation or warranty of the Company set forth in this Agreement or otherwise impair the rights and remedies available to Parent and Acquisition Sub hereunder.

Any access to the properties of the Company shall be subject to the terms and conditions of any applicable Lease and the Company’s reasonable security measures and insurance requirements and shall not include the right to perform Phase 1 or Phase 2 environmental assessments or other invasive testing without the Company’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed).

The Surviving Corporation shall (and Parent shall cause the Surviving Corporation to) honor and fulfill in all respects the obligations of the Company under any and all (i) indemnification agreements (A) listed in Section 3.12(xiii) of the Company Disclosure Letter between the Company and its current or former directors and officers and (B) between the Company and any person who becomes a director or officer of the Company prior to the Effective Time to the extent permitted pursuant to the terms of this Agreement (provided that any such indemnification agreement entered into with any person who becomes a director or officer of the Company following the date of this Agreement in accordance with the terms hereof shall be in substantially the same form as the indemnification agreements listed in Section 3.12(xiii) of the Company Disclosure Letter) (the “Indemnified Persons”) and (ii) the indemnification, expense advancement and exculpation provisions in any certificate of incorporate

-61-

or bylaws or comparable organizational document of the Company in effect on the date of this Agreement. In addition, during the period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time, the Surviving Corporation shall (and Parent shall cause the Surviving Corporation to) cause the certificates of incorporation and bylaws (and other similar organizational documents) of the Surviving Corporation to contain provisions with respect to indemnification, exculpation and the advancement of expenses that are at least as favorable as the indemnification, exculpation and advancement of expenses provisions contained in the certificates of incorporation and bylaws (or other similar organizational documents) of the Company as of the date of this Agreement, and during such six-year period, such provisions shall not be repealed, amended or otherwise modified in any manner that would adversely affect the rights thereunder of any Indemnified Person except as required by applicable Law.

(b) Indemnification Obligation. Without limiting the generality of the provisions of Section 6.8(a), during the period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time, to the fullest extent permitted by applicable Law, the Surviving Corporation shall (and Parent shall cause the Surviving Corporation to) indemnify and hold harmless each Indemnified Person from and against any costs, fees and expenses (including reasonable attorneys’ fees and investigation expenses), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement in connection with any claim, proceeding, investigation or inquiry, whether civil, criminal, administrative or investigative, to the extent such claim, proceeding, investigation or inquiry arises directly or indirectly out of, or pertains directly or indirectly to any action or omission or alleged action or omission in such Indemnified Person’s capacity as a director or officer of the Company (regardless of whether such action or omission, or alleged action or omission) occurred prior to, at or after the Effective Time (including in connection with any of the transactions contemplated by this Agreement); provided, however, that if, at any time prior to the sixth anniversary of the Effective Time, any Indemnified Person delivers to Parent a written notice asserting a claim for indemnification under this Section 6.8(b), then the claim asserted in such notice shall survive the sixth anniversary of the Effective Time until such time as such claim is fully and finally resolved. In addition, during the period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time, to the fullest extent permitted by applicable Law, the Surviving Corporation shall (and Parent shall cause the Surviving Corporation to) advance, prior to the final disposition of any claim, proceeding, investigation or inquiry for which indemnification may be sought under this Agreement, promptly following request by an Indemnified Person therefor, all costs, fees and expenses (including reasonable attorneys’ fees and investigation expenses) incurred by such Indemnified Person in connection with any such claim, proceeding, investigation or inquiry upon receipt of an undertaking by such Indemnified Person to repay such advances if it is ultimately decided in a final, non-appealable judgment by a court of competent jurisdiction that such Indemnified Person is not entitled to indemnification. In the event of any such claim, proceeding, investigation or inquiry, (i) the Surviving Corporation shall have the right to control the defense thereof after the Effective Time (it being understood that, by electing to control the defense thereof, the Surviving Corporation will be deemed to have waived any right to object to the Indemnified Person’s entitlement to indemnification hereunder with respect thereto), (ii) each Indemnified Person shall be entitled to retain his or her own counsel, whether or not the Surviving Corporation shall elect to control the defense of any such claim, proceeding, investigation or inquiry, (iii) subject to the receipt of the undertaking referred to in the preceding sentence, the Surviving Corporation shall pay all reasonable fees and expenses of any counsel retained by an Indemnified Person, promptly after

-62-

statements therefor are received, whether or not the Surviving Corporation shall elect to control the defense of any such claim, proceeding, investigation or inquiry, and (iv) no Indemnified Person shall be liable for any settlement effected without his or her prior express written consent; provided that such consent is not unreasonably withheld, conditioned or delayed. Notwithstanding anything to the contrary set forth in this Section 6.8(b) or elsewhere in this Agreement, neither the Surviving Corporation nor any of its Affiliates (including Parent) (A) shall settle or otherwise compromise or consent to the entry of any judgment or otherwise seek termination with respect to any claim, proceeding, investigation or inquiry for which indemnification may be sought by an Indemnified Person under this Agreement unless such settlement, compromise, consent or termination includes an unconditional release of all Indemnified Persons from all liability arising out of such claim, proceeding, investigation or inquiry, (B) shall be liable for any settlement effected without their prior written consent (which consent shall not be unreasonably withheld, delayed or conditioned) or (C) shall have any obligation hereunder to any Indemnified Person if it is ultimately decided in a final, non-appealable judgment by a court of competent jurisdiction that such indemnification is prohibited by applicable Law, in which case the Indemnified Person shall promptly refund to Parent or the Surviving Corporation the amount of all such expenses theretofore advanced pursuant hereto.

(c) D&O Insurance. During the period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time, the Surviving Corporation shall (and Parent shall cause the Surviving Corporation to) maintain in effect the Company’s current directors’ and officers’ liability insurance (“D&O Insurance”) in respect of acts or omissions occurring at or prior to the Effective Time, covering each person covered by the D&O Insurance, on terms with respect to the coverage and amounts that are no less favorable than those of the D&O Insurance; provided, however, that in satisfying its obligations under this Section 6.8(c), Parent and the Surviving Corporation shall not be obligated to pay annual premiums in excess of 300 percent of the amount paid by the Company for coverage for its last full fiscal year (such 300 percent amount, the “Maximum Annual Premium”) (which premiums the Company represents and warrants to be as set forth in Section 6.8(c) of the Company Disclosure Letter); provided, however, that, if the annual premiums of such insurance coverage exceed such amount, Parent and the Surviving Corporation shall be obligated to obtain a policy with the greatest coverage available for a cost not exceeding the Maximum Annual Premium. Prior to the Effective Time, notwithstanding anything to the contrary set forth in this Agreement, the Company may purchase a six-year “tail” prepaid policy on the D&O Insurance. In the event that the Company elects to purchase such a “tail” policy prior to the Effective Time, the Surviving Corporation shall (and Parent shall cause the Surviving Corporation to) maintain such “tail” policy in full force and effect and continue to honor their respective obligations thereunder, in lieu of all other obligations of Parent and the Surviving Corporation under the first sentence of this Section 6.8(c) for so long as such “tail” policy shall be maintained in full force and effect.

(d) Successors and Assigns. If Parent or the Surviving Corporation or any of its successors or assigns shall (i) consolidate with or merge into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) transfer all or substantially all of its properties and assets to any Person, then, and in each such case, proper provisions shall be made so that the successors and assigns of the Surviving Corporation shall assume all of the obligations of Parent and the Surviving Corporation set forth in this Section 6.8.

-63-

(e) No Impairment; Third Person Beneficiary Rights. The obligations set forth in this Section 6.8 shall not be terminated, amended or otherwise modified in any manner that adversely affects any Indemnified Person (or any other person who is a beneficiary under the D&O Insurance or the “tail” policy referred to in Section 6.8(c) (and their heirs and representatives)) without the prior written consent of such affected Indemnified Person or other person who is a beneficiary under the D&O Insurance or the “tail” policy referred to in Section 6.8(c) (and their heirs and representatives). Each of the Indemnified Persons or other persons who are beneficiaries under the D&O Insurance or the “tail” policy referred to in Section 6.8(c) (and their heirs and representatives) are intended to be third party beneficiaries of this Section 6.8, with full rights of enforcement as if a party thereto. The rights of the Indemnified Persons (and other persons who are beneficiaries under the D&O Insurance or the “tail” policy referred to in Section 6.8(c) (and their heirs and representatives)) under this Section 6.8 shall be in addition to, and not in substitution for, any other rights that such persons may have under the certificates of incorporation, bylaws or other equivalent organizational documents, any and all indemnification agreements of or entered into by the Company or any of its Subsidiaries, or applicable Law (whether at law or in equity).

(f) Joint and Several Obligations. The obligations and liability of Parent, the Surviving Corporation and their respective Subsidiaries under this Section 6.8 shall be joint and several.

(g) Other Claims. Nothing in this Agreement is intended to, shall be construed to or shall release, waive or impair any rights to directors’ and officers’ insurance claims under any policy that is or has been in existence with respect to the Company or any of its Subsidiaries for any of their respective directors, officers or other employees, it being understood and agreed that the indemnification provided for in this Section 6.8 is not prior to or in substitution for any such claims under such policies.

6.9 Employee Matters.

(a) 401(k) Termination. Unless Parent provides written notice to the Company that such plans intended to qualify as qualified cash or deferred arrangements under Section 401(k) of the Code (each, a “401(k) Plan”) shall not be terminated no later than three (3) Business Days prior to the Acceptance Time, the Company shall terminate any and all 401(k) Plans maintained by the Company or any ERISA Affiliates, in each case effective as of the day immediately preceding the date the Company becomes a member of the same Controlled Group of Corporations (as defined in Section 414(b) of the Code) as Parent (the “401(k) Termination Date”). The Company shall provide Parent evidence that the 401(k) Plan(s) of the Company have been terminated pursuant to resolutions of the Company Board. If the 401(k) Plan(s) described in this section have been terminated as of the 401(k) Termination Date, Parent shall use its commercially reasonable efforts to permit Continuing Employees to roll over their account balances (but not loans) to a 401(k) Plan of Parent or an Affiliate.

(b) Existing Arrangements. From and after the Acceptance Time, the Surviving Corporation shall (and Parent shall cause the Surviving Corporation to) honor all Employee Plans in accordance with their terms as in effect immediately prior to the Acceptance Time, provided, however, that nothing in this sentence shall prohibit the Surviving Corporation or its Subsidiaries from amending or terminating, or from causing the Surviving Corporation or its Subsidiaries to amend or terminate, any such Employee Plans, arrangements or agreements in accordance with their terms or if otherwise required by applicable Law.

-64-

(c) In-Cycle Bonuses. Parent shall, or shall cause the Surviving Corporation to, pay to each Continuing Employee otherwise eligible thereto, their target bonus for the calendar year in which the Effective Time occurs pursuant to the Company’s annual bonus plan (assuming 100% achievement of any performance objectives and 100% achievement with respect to any individual component for which no performance objectives were established), in the amounts set forth on Section 6.9(c) of the Company Disclosure Letter, which payments shall be paid to such Continuing Employees (i) at the same time as annual bonuses are paid to the employees of the Parent for the calendar year to which such annual bonuses relate. For the avoidance of doubt, this Section 6.9(c) shall not require Parent to provide, or to cause the Surviving Corporation to provide, any Continuing Employee with a payment under clause (ii) of this Section 6.9(c) if such payment would result in the Continuing Employee receiving a duplicate payment of his or her target bonus for the calendar year in which the Effective Time occurs where such Continuing Employee is entitled to the payment of such target bonus, or any portion thereof, as a result of such Continuing Employee’s involuntarily terminated under circumstances that entitle him or her to severance under any Employee Plan set forth on Section 3.16(i) of the Company Disclosure Letter. The payments described in this Section 6.9(c) shall represent the only annual bonus entitlement to which any Continuing Employee shall be eligible for the calendar year in which the Effective Time occurs, and neither Parent nor the Surviving Corporation shall be required to include the Continuing Employees in any annual bonus plan maintained by the Parent or Surviving Corporation for the remainder of such year.

(d) Employment; Benefits. During the period commencing at the Acceptance Time and ending one year following the Effective Time, the Surviving Corporation and its Subsidiaries shall (and Parent shall cause the Surviving Corporation and its Subsidiaries to) provide compensation, benefits and severance benefits (other than equity-based benefits and, subject to Section 6.9(b), individual employment agreements) to each Continuing Employee that, taken as a whole, are no less favorable in the aggregate than the compensation, benefits and severance benefits (other than equity-based benefits and individual employment agreements) provided to similarly-situated employees of Parent and its Subsidiaries. In each case, base salary or hourly wage rates shall not be decreased from the levels set forth in the material made available to Parent pursuant to Section 3.17(a) during the period commencing at the Acceptance Time and ending one year following the Effective Time for any Continuing Employee employed during that period.

(e) New Plans. With respect to the employee benefit plans maintained by Parent and its Subsidiaries that are offered to the Continuing Employees after the Effective Time (including any Employee Plans) (the “New Plans”), the Surviving Corporation and its Subsidiaries shall (and Parent shall cause the Surviving Corporation and its Subsidiaries to) cause to be granted to such Continuing Employee credit for all service with the Company and any predecessor employer prior to the Effective Time for purposes of eligibility to participate, vesting and entitlement to benefits where length of service is relevant (including for purposes of vacation, sick time or paid time off accrual and severance pay entitlement) to the same extent as such Continuing Employee was entitled, before the Effective Time, to credit for such service under any similar

-65-

Employee Plan in which such Continuing Employee participated or was eligible to participate immediately prior to the Effective Time; provided, however, that such service need not be credited to the extent that it would result in duplication of coverage or benefits. In addition, and without limiting the generality of the foregoing, Parent shall use its reasonable best efforts to (i) cause each Continuing Employee to be immediately eligible to participate, without any waiting period, in any and all New Plans to the extent that coverage pursuant to any such New Plan replaces coverage pursuant to a comparable Employee Plan in which such Continuing Employee participates immediately before the Acceptance Time and/or immediately before the Effective Time; (ii) for purposes of each New Plan providing medical, dental, pharmaceutical, vision or disability benefits to any Continuing Employee, cause all waiting periods, pre-existing condition exclusions, evidence of insurability requirements and actively-at-work or similar requirements of such New Plan to be waived for such Continuing Employee and his or her covered dependents; and (iii) cause any eligible expenses incurred by such Continuing Employee and his or her covered dependents during the portion of the plan year of the Employee Plan ending on the date that such Continuing Employee’s participation in the corresponding New Plan begins to be given full credit pursuant to such New Plan for purposes of satisfying all deductible, coinsurance and maximum out-of-pocket requirements applicable to such Continuing Employee and his or her covered dependents for the applicable plan year as if such amounts had been paid in accordance with such New Plan. Any vacation or paid time off accrued but unused by a Continuing Employee as of immediately prior to the Effective Time shall be credited to such Continuing Employee following the Effective Time, and shall not be subject to accrual limits or other forfeiture and shall not limit future accruals.

(f) No Third Person Beneficiary Rights. Notwithstanding anything to the contrary set forth in this Agreement, no provision of this Agreement shall be deemed to (i) guarantee employment for any period of time for, or preclude the ability of Parent, the Surviving Corporation or their Subsidiaries to terminate, any Continuing Employee for any reason, or (ii) require Parent, the Surviving Corporation or any of their Subsidiaries to continue any Employee Plan or New Plan or prevent the amendment, modification or termination thereof after the Effective Time. No provision of this Agreement shall create any third party beneficiary rights in any employee of the Company, any beneficiary or dependents thereof, with respect to the compensation, terms and conditions of employment and benefits that may be provided to any employee of the Company or any of its Subsidiaries by Parent, the Surviving Corporation or any of their Affiliates or under any benefit plan which any of them may maintain, or otherwise. No provision of this Agreement shall operate as an amendment to any benefit plan maintained by the Company or Parent or their respective Subsidiaries.

6.10 Rule 14d-10 Matters. Notwithstanding anything herein to the contrary, the Company shall not, from and after the date hereof and until the Effective Time, enter into, establish, amend or modify any plan, program, agreement or arrangement pursuant to which compensation is paid or payable, or pursuant to which benefits are provided, in each case to any current or former director, manager, officer, employee or independent contractor of the Company, unless prior to such entry into, establishment, amendment or modification, the Company Compensation Committee (each member of which the Company Board determined is an “independent director” within the meaning of the applicable NASDAQ rules and shall be an “independent director” in accordance with the requirements of Rule 14d-10(d)(2) under the Exchange Act at the time of any such action) shall have taken all such steps as may reasonably be necessary to (a) approve as an Employment Compensation Arrangement each such plan, program,

-66-

agreement or arrangement and (b) satisfy the requirements of the non-exclusive safe harbor under Rule 14d-10(d)(2) under the Exchange Act with respect to such plan, program, agreement or arrangement; provided that nothing in this Section 6.10 shall be construed to permit the Company to take any action that is prohibited by the terms of this Agreement.

6.11 Obligations of Acquisition Sub. Parent shall take all action necessary to cause Acquisition Sub and the Surviving Corporation to perform their respective obligations under this Agreement and to consummate the transactions contemplated in this Agreement upon the terms and subject to the conditions set forth in this Agreement. Parent and Acquisition Sub shall be jointly and severally liable for the failure by either of them to perform and discharge any of their respective covenants, agreements and obligations pursuant to this Agreement.

The Company shall give Parent the opportunity to participate with the Company in the defense or settlement of any such stockholder litigation and shall consider Parent’s views with respect to such stockholder litigation. Notwithstanding anything to the contrary contained herein, the Company shall not settle or enter into any negotiation regarding settlement in connection with such Legal Proceedings without the prior written consent of Parent (which shall not be unreasonably withheld, delayed or conditioned).

6.14 Additional Agreements. If at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full title to all properties, assets, rights, approvals, immunities and franchises of either of the Company or Acquisition Sub, then the proper officers and directors of each Party will use their reasonable best efforts to take such action.

Except as set forth in Section 2.8(d), Parent will pay or cause to be paid all (i) transfer, stamp and documentary Taxes or fees; and (ii) sales, use, real property transfer and other similar Taxes or fees, in each case arising out of or in connection with entering into this Agreement and the consummation of the Offer or the Merger.

(b) Company Payments.

(i) In the event that: (A) this Agreement is terminated by Parent or the Company pursuant to Section 8.1(b) (provided that the Minimum Condition has not been satisfied at the time of such termination and the conditions to the Offer set forth in Section 1.1(b)(ii) and Section 1.1(b)(iii)(A) have been satisfied at the time of such termination) or by Parent pursuant to Section 8.1(d); (B) following the execution and delivery of this Agreement and prior to the termination of this Agreement pursuant to Section 8.1(b) or Section 8.1(d) a Competing Acquisition Transaction shall have been publicly announced or shall have become publicly disclosed; and (C) within 12 months following the termination of this Agreement pursuant to Section 8.1(b) or Section 8.1(d), the Company enters into a Contract with any third party with respect to any Competing Acquisition Transaction (which Competing Acquisition Transaction is subsequently consummated, whether during or following such 12-month period) or any Competing Acquisition Transaction is consummated, the Company shall pay to Parent the Company Termination Fee, by wire transfer of immediately available funds to an account or accounts designated in writing by Parent, prior to or contemporaneously with the consummation of such Competing Acquisition Transaction. For purposes of only subclause (C) of the foregoing, a “Competing Acquisition Transaction” shall have the same meaning as an “Acquisition Transaction” except that all references in this Agreement to “more than 20 percent” shall be deemed to be references to “a majority.”

(ii) In the event that this Agreement is terminated by the Company pursuant to Section 8.1(e), the Company shall pay to Parent the Company Termination Fee, by wire transfer of immediately available funds to an account or accounts designated in writing by Parent, as a condition to the effectiveness of such termination.

(iii) In the event that this Agreement is terminated by Parent pursuant to Section 8.1(f), the Company shall pay to Parent the Company Termination Fee, by wire transfer of immediately available funds to an account or accounts designated in writing by Parent, as promptly as practicable (and in any event within two Business Days) after such termination by Parent.

(c) Single Payment Only; Liquidated Damages. The Parties acknowledge and agree that in no event will the Company be required to pay the Company Termination Fee, on more than one occasion, whether or not the Company Termination Fee may be payable pursuant to more than one provision of this Agreement at the same or at different times and upon the occurrence of different events. The Parties acknowledge and agree that (i) the agreements contained in this Section 8.3 are an integral part of the transactions contemplated by this Agreement; (ii) the damages resulting from the termination of this Agreement under circumstances where the Company Termination Fee is payable are uncertain and incapable of accurate calculation; (iii) in the event that Parent shall receive the Company Termination Fee, none of Parent, Acquisition Sub, any of their respective Affiliates or any other Person shall be entitled to

-72-

bring or maintain any other claim, action or proceeding against the Company or any of its Affiliates arising out of this Agreement (other than in the case of fraud by the Company in connection with the transaction contemplated by this Agreement or a willful and intentional breach of this Agreement by the Company) and (iv) without these agreements, the Parties would not enter into this Agreement. Therefore, the Company Termination Fee, if, as and when required to be paid pursuant to this Section 8.3 will not constitute a penalty but rather liquidated damages in a reasonable amount that will compensate Parent receiving such amount in the circumstances in which it is payable for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the Merger; provided, that payment of the Company Termination Fee shall not constitute liquidated damages in the case of fraud by the Company in connection with the transaction contemplated by this Agreement or a willful and intentional breach of this Agreement by the Company.

(d) Payments; Default. The Parties acknowledge and agree that the agreements contained in this Section 8.3 are an integral part of the transactions contemplated in this Agreement and that, without these agreements, the Parties would not enter into this Agreement. Accordingly, if the Company fails to promptly pay any amount due pursuant to Section 8.3(b) and, in order to obtain such payment, Parent commences a Legal Proceeding that results in a judgment against the Company for the amount set forth in Section 8.3(b) or any portion thereof, then the Company will pay or cause to be paid to Parent the reasonable and documented out-of-pocket costs and expenses (including reasonable and documented attorneys’ fees) of Parent and Acquisition Sub in connection with such Legal Proceeding, together with interest on such amount or portion thereof at an annual rate equal to the prime rate (as published in The Wall Street Journal in effect on the date that such payment or portion thereof was required to be made) plus five percent through the date that such payment or portion thereof was actually received, or a lesser rate that is the maximum permitted by applicable Law.

(e) Sole and Exclusive Remedy.

(i) [INTENTIONALLY OMITTED]

(ii) For Parent. If this Agreement is validly terminated pursuant to Section 8.1, Parent’s receipt of the Company Termination Fee, as applicable, to the extent owed pursuant to Section 8.3(b), and the amounts described in Section 8.3(d), and Parent’s right to specific performance pursuant to Section 9.11 will be the sole and exclusive remedies of Parent and Acquisition Sub against (A) the Company; and (B) the former, current and future holders of any equity, controlling persons, Representatives, Affiliates, members, managers, general or limited partners, stockholders and assignees of each of the Company and each of their respective Affiliates (the Persons in clauses (A) and (B) collectively, the “Company Related Parties”) in respect of this Agreement, the Offer and the Merger. Upon payment of the Company Termination Fee and any applicable amount described in Section 8.3(d), none of the Company Related Parties will have any further monetary liability or obligation to Parent or Acquisition Sub relating to or arising out of this Agreement, the Offer or the Merger (except that the Company (or its Affiliates) will remain obligated with respect to, and Parent and Acquisition Sub may be entitled to remedies with respect to, the Confidentiality Agreement, Section 8.2 and Section 8.3, as applicable); provided, that nothing in this Section 8.3(e) shall relieve the Company from any liabilities or damages resulting from any fraud or willful and intentional breach of this Agreement prior to or in connection with such termination.

-73-

(f) Acknowledgement Regarding Specific Performance. Notwithstanding anything to the contrary in this Agreement, it is acknowledged and agreed that Parent, Acquisition Sub and the Company will each be entitled to an injunction, specific performance or other equitable relief as provided in Section 9.11, except that, although Parent, in its sole discretion, may determine its choice of remedies under this Agreement, including by pursuing specific performance in accordance with, but subject to the limitations of, Section 9.11, under no circumstances will Parent, directly or indirectly, be permitted or entitled to receive both specific performance of the type contemplated by Section 9.11 (other than a grant of specific performance ordering payment of the Company Termination Fee) and the Company Termination Fee.

(q) Joint Drafting. The Parties agree that they have been represented by legal counsel during the negotiation and execution of this Agreement.

(t) No Reliance by Others on Representations. The representations and warranties in this Agreement are the product of negotiations among the Parties and are for the sole benefit of the Parties. Any inaccuracies in such representations and warranties are subject to waiver by the Parties in accordance with Section 9.6 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 of risks associated with particular matters regardless of the knowledge of any of the Parties. Consequently, Persons other than the Parties may not rely on the representations and warranties in this Agreement as characterizations of facts or circumstances as of the date of this Agreement or as of any other date.

-76-

Any assignment in violation of this Section 9.4 shall be null and void.

-78-

9.5 Amendment. Subject to applicable Law and subject to the other provisions of this Agreement, this Agreement may be amended by the Parties at any time by execution of an instrument in writing signed on behalf of each of Parent, Acquisition Sub and the Company (pursuant to authorized action by the Company Board (or a committee thereof)); provided, however, that in the event that this Agreement has been adopted by the Company Stockholders in accordance with Delaware Law, no amendment shall be made to this Agreement that requires the approval of such Company Stockholders under Delaware Law without such approval.

9.6 Extension; Waiver. At any time and from time to time prior to the Effective Time, any Party may, to the extent legally allowed and except as otherwise set forth in this Agreement, (a) extend the time for the performance of any of the obligations or other acts of the other Parties, as applicable, (b) waive any inaccuracies in the representations and warranties made to such Party in this Agreement or in any document delivered pursuant to this Agreement and (c) subject to the requirements of applicable Law, waive compliance with any of the agreements or conditions for the benefit of such Party contained in this Agreement. Any agreement on by a Party to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such Party. Any delay in exercising any right under this Agreement shall not constitute a waiver of such right.

9.7 Confidentiality. Parent, Acquisition Sub and the Company acknowledge that Parent and the Company have previously executed the Confidentiality Agreement, which will continue in full force and effect in accordance with its terms. Each of Parent, Acquisition Sub and their respective Representatives will hold and treat all documents and information concerning the Company and its Subsidiaries furnished or made available to Parent, Acquisition Sub or their respective Representatives in connection with the Merger in accordance with the Confidentiality Agreement. By executing this Agreement, each of Parent and Acquisition Sub agree to be bound by, and to cause their Representatives to be bound by, the terms and conditions of the Confidentiality Agreement as if they were the counterparty thereto.

9.8 Entire Agreement. This Agreement and the documents and instruments and other agreements among the Parties as contemplated by or referred to in this Agreement, including the Company Disclosure Letter and Parent Disclosure Letter, the Annexes hereto, the Support Agreements and the Confidentiality Agreement, constitute the entire agreement among the Parties with respect to the subject matter of this Agreement and supersede all prior agreements and understandings, both written and oral, among the Parties with respect to the subject matter of this Agreement; provided, however, the Confidentiality Agreement shall not be superseded, shall survive any termination of this Agreement and shall continue in full force and effect until the earlier to occur of (a) the Effective Time and (b) the date on which the Confidentiality Agreement expires in accordance with its terms or is validly terminated.

9.9 No Third Party Beneficiaries. The Parties agree that their respective representations, warranties and covenants set forth in this Agreement are solely for the benefit of the other Parties in accordance with and subject to the terms of this Agreement. This Agreement is not intended to, and shall not, confer upon any other Person any rights or remedies hereunder, except (a) as set forth in or contemplated by the terms and provisions of Section 6.8, (b) from and after the Acceptance Time, the rights of holders of shares of the Company Common Stock and other Company Securities to receive the consideration pursuant to the Offer, as set forth in Article I, and (c) from and after the Effective Time, the rights of holders of shares of the Company Common Stock and other Company Securities to receive the consideration pursuant to the Merger, as set forth in Article II,

-79-

9.10 Severability. In the event that any provision of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement will continue in full force and effect and the application of such provision to other persons or circumstances will be interpreted so as reasonably to effect the intent of the Parties. The Parties further agree to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision.

9.11 Remedies.

(a) Remedies Cumulative. Subject to Sections 8.3(b) through (c), and except as otherwise provided in this Agreement, any and all remedies in this Agreement expressly conferred upon a Party will be deemed cumulative with and not exclusive of any other remedy conferred by this Agreement, or by law or equity upon such Party, and the exercise by a Party of any one remedy will not preclude the exercise of any other remedy.

(b) Specific Performance.

(i) Irreparable Damage. The Parties agree that irreparable damage for which monetary damages or other legal remedies, even if available, would not be an adequate remedy, would occur in the event that any provision of this Agreement were not performed in accordance with its specific terms or were otherwise breached. The Parties acknowledge and agree that (A) the Parties will be entitled, in addition to any other remedy to which they are entitled at law or in equity, to an injunction, specific performance and other equitable relief to prevent breaches (or threatened breaches) of this Agreement and to enforce specifically the terms of this Agreement; (B) the provisions of Section 8.3 are not intended to and do not adequately compensate the Company, on the one hand, or Parent and Acquisition Sub, on the other hand, for the harm that would result from a breach of this Agreement, and will not be construed to diminish or otherwise impair in any respect any Party’s right to an injunction, specific performance and other equitable relief; and (C) the right of specific enforcement is an integral part of the Merger and without that right, neither the Company nor Parent would have entered into this Agreement.

(ii) No Objections. The Parties agree not to raise any objections to (A) the granting of an injunction, specific performance or other equitable relief to prevent or restrain breaches or threatened breaches of this Agreement by the Company, on the one hand, or Parent and Acquisition Sub, on the other hand; and (B) the specific performance of the terms and provisions of this Agreement to prevent breaches or threatened breaches of, or to enforce compliance with, the covenants, obligations and agreements of the Parties pursuant to this Agreement. Any Party seeking an injunction or injunctions to prevent breaches (or threatened breaches) of this Agreement and to enforce specifically the terms and provisions of this Agreement will not be required to provide any bond or other security in connection with such injunction or enforcement, and each Party irrevocably waives any right that it may have to require the obtaining, furnishing or posting of any such bond or other security.

-80-

(iii) Other Relief. The Parties further agree that (x) by seeking the remedies provided for in this Section 9.11(b), a Party shall not in any respect waive its right to seek any other form of relief that may be available to a Party under this Agreement (including monetary damages) in the event that this Agreement has been terminated or in the event that the remedies provided for in this Section 9.11(b) are not available or otherwise are not granted and (y) nothing set forth in this Section 9.11(b) shall require any Party to institute any proceeding for (or limit any Party’s right to institute any proceeding for) specific performance under this Section 9.11(b) prior or as a condition to exercising any termination right under Article IX (and pursuing damages after such termination), nor shall the commencement of any Legal Proceeding pursuant to this Section 9.11(b) or anything set forth in this Section 9.11(b) restrict or limit any Party’s right to terminate this Agreement in accordance with the terms of Article IX or pursue any other remedies under this Agreement that may be available then or thereafter.

9.12 Governing Law. This Agreement shall be governed by and construed in accordance with the Laws of the State of Delaware, regardless of the Laws that might otherwise govern under applicable principles of conflicts of law thereof.

9.13 Consent to Jurisdiction. Each of the Parties (a) irrevocably consents to the service of the summons and complaint and any other process (whether inside or outside the territorial jurisdiction of the Chosen Courts) in any Legal Proceeding relating to the transactions contemplated by this Agreement or any claim or cause of action arising in connection with this Agreement or the negotiation hereof, for and on behalf of itself or any of its properties or assets, in accordance with Section 9.3 or in such other manner as may be permitted by applicable Law, but nothing in this Section 9.13 shall affect the right of any Party to serve legal process in any other manner permitted by applicable Law; (b) irrevocably and unconditionally consents and submits itself and its properties and assets in any Legal Proceeding to the exclusive jurisdiction of the Chosen Courts in the event any dispute or controversy arises out of or relating to this Agreement or the transactions contemplated in this Agreement or the negotiation of this Agreement, or for recognition and enforcement of any judgment in respect thereof; (c) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any Chosen Court; (d) agrees that any Legal Proceedings arising in connection with or relating to this Agreement or the transactions contemplated in this Agreement or the negotiation of this Agreement shall be brought, tried and determined only in the Chosen Courts; (e) waives any objection that it may now or hereafter have to the venue of any such Legal Proceeding in the Chosen Courts or that such Legal Proceeding was brought in an inconvenient court and agrees not to plead or claim the same; and (f) agrees that it will not bring any Legal Proceeding relating to or arising out of this Agreement or the transactions contemplated hereby or the negotiation hereof in any court other than the Chosen Courts. Each of Parent, Acquisition Sub and the Company agrees that a final judgment in any Legal Proceeding in the Chosen Courts shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Law.

9.14 WAIVER OF JURY TRIAL. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY THAT MAY ARISE PURSUANT TO THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT THAT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY

-81-

LEGAL PROCEEDING (WHETHER FOR BREACH OF CONTRACT, TORTIOUS CONDUCT OR OTHERWISE) DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE MERGER. EACH PARTY ACKNOWLEDGES AND AGREES 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 THE FOREGOING WAIVER; (b) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER; (c) IT MAKES THIS WAIVER VOLUNTARILY; AND (d) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.14.

9.15 Company Disclosure Letter and Parent Disclosure Letter Matters.

(a) No Admission. The information set forth in this Agreement, in the Company Disclosure Letter and the Parent Disclosure Letter is disclosed solely for purposes of this Agreement, and no information contained in this Agreement, the Company Disclosure Letter or the Parent Disclosure Letter will be deemed to be an admission by any Party to any third Person of any matter whatsoever, including (i) any violation of Law or breach of Contract, or (ii) that such information is material. Nothing in the Company Disclosure Letter or the Parent Disclosure Letter constitutes an admission against the Company’s or the Parent’s, as applicable, interest or represents the Company’s or the Parent’s, as applicable, legal position or legal rights on the matter so disclosed. No reference in this Agreement to dollar amount thresholds will be deemed to be evidence of a Company Material Adverse Effect or materiality.

(b) Exceptions. The Parties agree that the disclosure set forth in any particular section or subsection of the Company Disclosure Letter or the Parent Disclosure Letter, as applicable, shall be deemed to be an exception to (or, as applicable, a disclosure for purposes of) (i) the representations and warranties (or covenants, as applicable) of the Company or the Parent, as applicable, that are set forth in the corresponding Section or subsection of this Agreement, and (ii) any other representations and warranties (or covenants, as applicable) of the Company or the Parent, as applicable, that are set forth in this Agreement, but, in the case of this clause (ii), only if the relevance of that disclosure as an exception to (or a disclosure for purposes of) such other representations and warranties (or covenants, as applicable) is reasonably apparent on the face of such disclosure.

9.16 Counterparts. This Agreement and any amendments to this Agreement may be executed in one or more textually identical counterparts, all of which will be considered one and the same agreement and will become effective when one or more counterparts have been signed by each of the Parties and delivered to the other Parties, it being understood that all Parties need not sign the same counterpart. Any such counterpart, to the extent delivered by fax or .pdf, .tif, .gif, .jpg or similar attachment to electronic mail (any such delivery, an “Electronic Delivery”), will be treated in all manner and respects as an original executed counterpart and will be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. No Party may raise the use of an Electronic Delivery to deliver a signature, or the fact that any signature or agreement or instrument was transmitted or communicated through the use of an Electronic Delivery, as a defense to the formation of a contract, and each Party forever waives any such defense, except to the extent such defense relates to lack of authenticity.

-82-

9.17 No Limitation. It is the intention of the Parties that, to the extent possible, unless provisions are mutually exclusive and effect cannot be given to both or all such provisions, (a) the representations, warranties, covenants and closing conditions in this Agreement will be construed to be cumulative; (b) each representation, warranty, covenant and closing condition in this Agreement will be given full, separate and independent effect; and (c) nothing set forth in any provision in this Agreement will (except to the extent expressly stated) in any way be deemed to limit the scope, applicability or effect of any other provision of this Agreement.
