THIS AGREEMENT AND PLAN OF MERGER AND REORGANIZATION

(together with all annexes, letters, schedules and exhibits hereto, this “Agreement”), dated as of August 12, 2010, is by and among Emergent BioSolutions Inc. a Delaware corporation (“Parent”), 35406 LLC, a Delaware limited liability company and wholly owned direct subsidiary of Parent (sometimes referred to herein as the “LLC” or the “Final Surviving Entity”), 30333 Inc., a Delaware corporation and wholly owned indirect subsidiary of Parent (sometimes referred to herein as “Merger Sub”), and Trubion Pharmaceuticals, Inc. a Delaware corporation (the “Company” or the “Interim Surviving Corporation”).

RECITALS

A. Parent, Merger Sub and the Company each has determined that it is advisable, fair to and in the best interests of its stockholders, to effect a merger (the “Merger”) of the Merger Sub with and into the Company, with the Company to be the surviving entity of the Merger, pursuant to the Delaware General Corporation Law (the “DGCL”) upon the terms and subject to the conditions set forth in this Agreement, pursuant to which each outstanding share of common stock, par value $0.001 per share, of the Company (the “Common Shares”), shall be converted into the right to receive an amount in cash from Parent and shares of the common stock, par value $0.001 per share, of Parent (the “Parent Common Stock”) and a right to receive a future cash payment, contingent upon the occurrence of certain events, in the form of a contingent value right (“CVR”), in each case as set forth herein and all upon the terms and subject to the conditions of this Agreement. Promptly following the Merger, Parent shall cause the Interim Surviving Corporation to merge (the “LLC Merger”) with and into the LLC, with the LLC to be the surviving entity of the LLC Merger pursuant to the LLC Act and the DGCL and upon the terms and conditions set forth in this Agreement. The transactions described in this Agreement are subject to the approval of the stockholders of the Company, the expiration of the required waiting period under the HSR Act and the satisfaction of certain other conditions described in this Agreement.

B. The Merger and the LLC Merger (collectively, the “Integrated Merger”) are intended to be part of an integrated plan and together are intended to qualify as a reorganization within the meaning of Section 368(a) of the Code of 1986, and this Agreement is intended to constitute a “plan of reorganization” within the meaning of the regulations promulgated under Section 368 of the Code.

C. The Board of Directors of the Company (the “Company Board of Directors”) has unanimously (i) determined that this Agreement, the Contingent Value Rights Agreement in substantially the form attached as Exhibit A (the “CVR Agreement”), the Merger and the other transactions contemplated hereby, taken together, are at a price and on terms that are fair to, advisable and in the best interests of the Company and its stockholders (the “Company Stockholders”) and (ii) adopted resolutions approving this Agreement, the CVR Agreement and the transactions contemplated hereby, including the Merger, declaring its advisability and recommending the adoption by the Company Stockholders of the “agreement of merger” (as such term is used in Section 251 of the DGCL) contained in this Agreement, and the Merger and the other transactions contemplated hereby.

D. The respective Boards of Directors of Parent (the “Parent Board of Directors”) and Merger Sub and, to the extent applicable, the Manager of the LLC, have (i) determined that this Agreement, the CVR Agreement, the Merger, the LLC Merger and the other transactions contemplated hereby, taken together, are at a price and on terms that are fair to, advisable and in the best interests of Parent, Merger Sub, the LLC and Parent’s stockholders, respectively, and (ii) adopted resolutions approving this Agreement, the CVR Agreement and the other transactions contemplated hereby, including the Merger and the LLC Merger, declaring the advisability thereof and recommending the adoption by Merger Sub’s sole stockholder of the “agreement of merger” (as such term is used in Section 251 of the DGCL) contained in this Agreement, and the Merger, the LLC Merger and the other transactions contemplated hereby. Parent, as the sole stockholder of Merger Sub has adopted the “agreement of merger” (as such term is used in Section 251 of the DGCL) contained in this Agreement and authorized the payment of cash consideration and the issuance of shares of Parent Common Stock pursuant to the terms of this Agreement.

E. Simultaneously with the execution and delivery of this Agreement, the Company, Parent, Merger Sub and the Exchange Agent have entered into the CVR Agreement.

F. Simultaneously with the execution and delivery of this Agreement, certain Company Stockholders (who in the aggregate hold beneficially or of record more than 35% of the outstanding Common Shares) have entered into a support agreement, in the form attached hereto as Exhibit B (the “Support Agreement”), dated as of the date hereof, with Parent, pursuant to which, among other things, such Company Stockholders have agreed to vote a pro rata portion of their shares, which when aggregated with all other shares subject to the Support Agreement, amount to 35% of the outstanding Common Shares, in favor of the Merger and against any competing proposals.

G. Simultaneously with the execution and delivery of this Agreement, the Company and the certain Company Stockholders holding rights under the Company Investor Rights Agreement have entered into an agreement terminating the Company Investor Rights Agreement, in the form attached hereto as Exhibit C (the “Termination Agreement”), effective as of the Effective Time, a duly executed copy of which has been made available to Parent.

H. Simultaneously with the execution and delivery of this Agreement, Parent has received a letter, in the form attached hereto as Exhibit D (the “Company Stockholder Letter”), from each Company Stockholder that is (A) an officer or director of the Company or a controlled Affiliate thereof and (B) holds more than five percent (5%) of the Common Shares immediately prior to the Effective Time, pursuant to which each such Company Stockholder has agreed, subject to certain events of early acceleration provided therein, to (i) refrain from selling any shares of Stock Merger Consideration (as defined below) received by such Company Stockholder for a period of ninety (90) days from the Effective Time, (ii) refrain from selling more than 25% of the shares of Stock Merger Consideration received by such Company Stockholder prior to the date that is one hundred eighty (180) days after the Effective Time, (iii) refrain from selling more than 50% of the shares of Stock Merger Consideration received by such Company Stockholder prior to the date that is two hundred seventy (270) days after the Effective Time and (iv) refrain from selling more than 75% of the shares of Stock Merger

Section 1.6 Directors, Managers and Officers.

(b) Section 3.3(b) to the Company Disclosure Letter sets forth each Cash-Out Option. Each Cash-Out Option which will have, at the Effective Time, a positive net exercise

value given the dollar value of the Initial Merger Consideration of $4.55 is marked with an asterisk thereon. Such Cash-Out Options, shall, by virtue of the Merger and without the need for any further action on the part of the Cash-Out Option Holder thereof, on the terms and subject to the conditions set forth in this Agreement, be canceled and extinguished and automatically converted by the Company into the right to receive for each Common Share subject to such Cash-Out Option (i) the Cash-Out Amount and (ii) a CVR; provided, however, that the Company shall be entitled to deduct and withhold from the Cash-Out Amount the amount of withholdings for Taxes required to be deducted and withheld as a result of the transaction contemplated by this Section 1.7(b). The Cash-Out Amount to be received by the Cash-Out Option Holder identified on Section 3.3(b) to the Company Disclosure Letter with an asterisk shall be rounded to the nearest cent and computed after aggregating the cash amounts for all Common Shares subject to the Cash-Out Options when paid promptly after the Effective Time.

(c) Any Cash-Out Option which has a negative exercise value given the dollar value of the Initial Merger Consideration of $4.55 and, as a result thereof, is not marked with an asterisk on Section 3.3(b) to the Company Disclosure Letter shall, by virtue of the Merger and without the need for any further action on the part of the Cash-Out Option Holder thereof, on the terms and subject to the conditions set forth in this Agreement, be canceled and extinguished without further Liability of the Company, Parent, the Interim Surviving Corporation or the Final Surviving Entity.

(d) Prior to the Effective Time, the Company shall take all such steps as may be required (to the extent permitted under applicable Law) to cause any dispositions of Common Shares (including, in each case, derivative securities) resulting from the transactions contemplated hereby by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Company to be exempt under Rule 16b-3 promulgated under the Exchange Act.

(e) All Company Option Plans shall terminate as of the Effective Time and the provisions in any Company Option Plans or any other plan providing for the issuance, transfer or grant of any capital stock of the Company or any interest in respect of any capital stock of the Company shall be deleted as of the Effective Time, and the Company shall take such action as is necessary to ensure that following the Effective Time no holder of a Company Stock Option or any participant in any Company Option Plans or any other plan shall have any right to acquire any capital stock of the Company, the Interim Surviving Corporation or the Final Surviving Entity, or any interest in respect of any capital stock of the Company, the Interim Surviving Corporation or the Final Surviving Entity.

(f) Prior to the Effective Time, the Company shall deliver to the holders of Company Stock Options notices, in form and substance reasonably acceptable to Parent, setting forth such holders’ rights pursuant to this Agreement. The holders of Company Stock Options will then exercise the rights as set forth in such notice.

Section 1.8 Appraisal Shares. Notwithstanding anything in this Agreement to the contrary, any Appraisal Shares shall not be converted into the right to receive the Merger Consideration as provided in Section 1.4, but instead such holders of Appraisal Shares shall be entitled to payment of the fair value of such shares in accordance with the provisions of Section

262. Notwithstanding the foregoing, if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to appraisal under Section 262 or a court of competent jurisdiction shall determine that such holder is not entitled to the relief provided by Section 262, then the right of such holder to be paid the fair value of such holder’s Appraisal Shares under Section 262 shall cease and such Appraisal Shares shall be deemed to have been converted at the Effective Time into, and shall have become, the right to receive the Merger Consideration as provided in Section 1.4 without interest. The Company shall serve prompt notice to Parent of any demands for appraisal of any of the Common Shares, attempted withdrawals of such demands and any other instruments served pursuant to the DGCL received by the Company, and Parent shall have the right to participate in and direct all negotiations and proceedings with respect to such demands. The Company shall not, without the prior written consent of Parent, or as otherwise required under the DGCL, voluntarily make any payment with respect to, or settle or offer to settle, any such demands, or agree to do or commit to do any of the foregoing.

Section 1.9 Adjustments to Prevent Dilution. Notwithstanding the restrictions contained in Section 5.1, in the event that the Company changes the number of Common Shares, or securities convertible or exchangeable into or exercisable for Common Shares, issued and outstanding prior to the Effective Time as a result of a reclassification, stock split (including a reverse stock split), stock dividend or distribution, recapitalization, merger, subdivision, issuer tender or exchange offer, or other similar transaction, the Merger Consideration shall be proportionately adjusted to reflect such change.

Section 1.10 Fractional Shares. Notwithstanding any other provision of this Agreement, each holder of Common Shares exchanged pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of Parent Common Stock (after taking into account all shares delivered by such holder and aggregating all fractional shares of Parent Common Stock to be received by such holder) shall receive, in lieu thereof, cash (without interest) in an amount equal to such fractional part of a share of Parent Common Stock multiplied by the Parent Average Stock Price. No such holder will be entitled to dividends, voting rights, or any other rights as a stockholder in respect to any fractional shares.

Section 1.11 Tax Consequences. It is intended by the parties hereto that, for United States federal income tax purposes, the Integrated Merger is intended to be part of an integrated plan and is intended to qualify as a “reorganization” within the meaning of Section 368(a) of the Code.

ARTICLE II

EXCHANGE OF CERTIFICATES

Section 2.1 Exchange Agent. The parties agree that Mellon Investor Services shall act as the Exchange Agent (the “Exchange Agent”). In the event that Mellon Investor Services is unwilling or unable to act as the Exchange Agent, Parent shall select another institution reasonably satisfactory to the Company to act as the Exchange Agent. At or prior to the Effective Time, Parent shall enter into an agreement with the Exchange Agent which shall provide that Parent shall deposit with the Exchange Agent on a timely basis, for exchange in accordance with this Article II, the shares of Parent Common Stock issuable pursuant to this

Agreement and cash in an amount sufficient to permit payment (a) of the aggregate Cash Merger Consideration and (b) cash in lieu of fractional shares pursuant to Section 1.10 (such cash and shares of Parent Common Stock being hereinafter referred to as the “Exchange Fund”), payable pursuant to Section 1.4 in exchange for outstanding Common Shares. Any income from investment of the Exchange Fund, which investment shall be made in accordance with the instructions of Parent, will be payable solely to Parent.

Section 2.2 Exchange Procedures.

(a) As soon as practicable and not later than five (5) Business Days after the Effective Time, the Exchange Agent shall mail to each holder of record of a Certificate or Certificates that, immediately prior to the Effective Time, represented outstanding Common Shares subsequently converted into the right to receive the Merger Consideration, as set forth in Section 1.4: (i) a letter of transmittal (a “Letter of Transmittal”) that (A) shall specify that delivery shall be effected and risk of loss and title to the Certificates shall pass only upon proper delivery of the Certificates to the Exchange Agent (or an affidavit of loss in lieu thereof, together with any bond or indemnity agreement, as contemplated by Section 2.6) and (B) shall be in such form and have such other provisions as the Interim Surviving Corporation or Parent may reasonably specify; and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration.

(b) Upon surrender of a Certificate for cancellation to the Exchange Agent, together with a Letter of Transmittal, duly completed and executed, and any other documents reasonably required by the Exchange Agent, Parent or the Interim Surviving Corporation, (i) the holder of such Certificate shall be entitled to receive in exchange therefor the number of shares of Parent Common Stock, the portion of the Cash Merger Consideration, and the CVRs to which such holder is entitled and (ii) the Certificate so surrendered shall forthwith be canceled. No interest will be paid or accrued on the cash payable upon surrender of the Certificates. Until surrendered as contemplated by this Section 2.2, each such Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the applicable Merger Consideration.

(c) In the event of a transfer of ownership of Common Shares that is not registered in the transfer records of the Company, the appropriate amount of the Merger Consideration may be paid to a transferee if the Certificate representing such Common Shares is presented to the Exchange Agent properly endorsed or accompanied by appropriate stock powers and otherwise in proper form for transfer and accompanied by all documents reasonably required by the Exchange Agent, Parent or the Interim Surviving Corporation to evidence and effect such transfer and to evidence that any applicable Taxes have been paid.

(d) No dividends or other distributions, if any, declared or made after the Effective Time with respect to Parent Common Stock with a record date after the Effective Time will be paid to the holder of any unsurrendered Certificate with respect to the shares of Stock Merger Consideration to be issued in exchange therefor until the holder of record of such Certificate shall surrender such Certificate in accordance with this Section 2.2. Subject to applicable Law, following surrender of any such Certificate, there shall be paid to the record holder of the certificates representing whole shares of the Stock Merger Consideration issued in

exchange therefor, without interest, at the time of such surrender, the amount of dividends or other distributions, if any, with a record date after the Effective Time theretofore paid with respect to such whole shares of the Stock Merger Consideration. No interest shall be payable on any cash deliverable upon the exchange of any Common Shares for Cash Merger Consideration.

Section 2.3 No Further Ownership Rights. All Merger Consideration paid upon the surrender for exchange of the Certificates representing Common Shares in accordance with the terms hereof shall be deemed to have been paid in full satisfaction of all rights pertaining to such Common Shares and, after the Effective Time, there shall be no further registration of transfers on the transfer books of the Interim Surviving Corporation of the Common Shares that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Interim Surviving Corporation or the Final Surviving Entity, for any reason, they shall be canceled and exchanged as provided in this Article II, subject to applicable Law in the case of Appraisal Shares.

Section 2.4 Termination of Exchange Fund. Any portion of the Exchange Fund (including any interest and other income received with respect thereto) that remains undistributed to the former Company Stockholders on the first anniversary of the Effective Time shall be delivered to the Final Surviving Entity upon demand, and any former holder of Common Shares who has not theretofore received any applicable Merger Consideration to which such Company Stockholder is entitled under this Article II shall thereafter look only to the Final Surviving Entity (subject to abandoned property, escheat or other similar Laws) for payment of claims with respect thereto and only as a general creditor thereof.

Section 2.5 No Liability. None of Parent, Merger Sub, the Interim Surviving Corporation or the Final Surviving Entity shall be liable to any holder of Common Shares for any part of the Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. Any amounts remaining unclaimed by holders of any such Common Shares two years after the Effective Time or at such earlier date as is immediately prior to the time at which such amounts would otherwise escheat to, or become property of, any Governmental Entity shall, to the extent permitted by applicable Law or Order, become the property of the Final Surviving Entity free and clear of any claims or interest of any such holders or their successors, assigns or personal representatives previously entitled thereto.

Section 2.6 Lost, Stolen or Destroyed Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by and at the discretion of Parent, the Interim Surviving Corporation or the Final Surviving Entity, the posting by such Person of a bond in such reasonable amount as Parent, the Interim Surviving Corporation or the Final Surviving Entity may direct, or the execution and delivery by such Person of an indemnity agreement in such form as Parent, the Interim Surviving Corporation or the Final Surviving Entity may direct, in each case as indemnity against any claim that may be made against Parent, the Interim Surviving Corporation or the Final Surviving Entity with respect to such Certificate, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Certificate the appropriate amount of the Merger Consideration.

Section 2.7 Withholding of Tax. Parent, the Interim Surviving Corporation, the Final Surviving Entity, any Affiliate thereof or the Exchange Agent shall be entitled to deduct and withhold from the Merger Consideration otherwise payable pursuant to this Agreement to any holder of Common Shares such amount as Parent, the Interim Surviving Corporation, the Final Surviving Entity, any Affiliate thereof or the Exchange Agent is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign Tax Law. To the extent that amounts are so withheld by Parent, the Interim Surviving Corporation, the Final Surviving Entity, any Affiliate thereof or the Exchange Agent, such withheld amounts shall be (a) paid over to the applicable Governmental Entity in accordance with applicable Law or Order and (b) treated for all purposes of this Agreement as having been paid to the former holder of a Certificate in respect of which such deduction and withholding was made.

(b) Neither the execution or delivery of this Agreement nor the consummation of the transactions contemplated by this Agreement will, alone or in conjunction with any other event (whether contingent or otherwise), (i) result in any material payment or benefit becoming due or payable, or required to be provided, to any current or former employee, director, independent contractor or consultant of the Company thereof, (ii) materially increase the amount or value of any benefit or compensation otherwise payable or required to be provided to any current or former employee, director, independent contractor or consultant of the Company, or (iii) result in the acceleration of the time of payment, vesting or funding of any such benefit or compensation.

Except in connection with the withdrawal or modification by the Company Board of Directors of its approvals or recommendations of the Merger or the transactions contemplated hereby and other than pursuant to Rule 425 of the Securities Act with respect to releases made in compliance with Section 5.8 of this Agreement, no amendment or supplement to the Proxy Statement or the Registration Statement, nor any response to any comments or inquiry from the SEC with respect to such filings, will be made by the Company or Parent without the approval of the other party, which approval shall not be unreasonably withheld, conditioned or delayed (it being understood that it shall be unreasonable to withhold consent with respect to any amendment or supplement to the Proxy Statement or Registration Statement to the extent such amendment or supplement is required to be included therein so that the Proxy Statement or Registration Statement will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they are made, not misleading as may be required by Rule 10b-5 or Rule 14a-9 under the Exchange Act or Section 11 or Section 12 of the Securities Act). The Company and Parent each will advise the other promptly after it receives notice of the time when the Registration Statement has become effective or any supplement or amendment has been filed, of the issuance of any stop order, the suspension of the qualification of the Parent Common Stock issuable in connection with the Merger for offering or sale in any jurisdiction, or any request by the SEC for amendment of the Proxy Statement or the Registration Statement or comments thereon and responses thereto or requests by the SEC for additional information. Each of the parties hereto shall cause the Proxy Statement and the Registration Statement to comply as to form and substance as to such party in

all material respects with the applicable requirements of (i) the Exchange Act, (ii) the Securities Act, and (iii) the rules and regulations of Nasdaq and the NYSE.

Section 5.6 Company Stockholders Meeting. After the Registration Statement is declared effective and the Proxy Statement is cleared by the SEC, the Company, acting through the Company Board of Directors, shall take all actions in accordance with applicable Law, the Company Certificate of Incorporation, the Company By-laws and the rules of Nasdaq to promptly and duly call, give notice of, convene and hold as promptly as practicable the Company Stockholders Meeting for the sole purpose of considering and voting upon the adoption of the “agreement of merger” (as such term is used in Section 251 of the DGCL) contained in this Agreement. Subject to Section 5.7(c), to the fullest extent permitted by applicable Law, (i) the Company Board of Directors shall recommend adoption of the “agreement of merger” (as such term is used in Section 251 of the DGCL) contained in this Agreement and approval of the Merger by the Company Stockholders and include such recommendation in the Proxy Statement and (ii) neither the Company Board of Directors nor any committee thereof shall withdraw or modify, or propose or resolve to withdraw or modify in a manner adverse to Parent, the recommendation of the Company Board of Directors that the Company Stockholders vote in favor of the adoption of the “agreement of merger” (as such term is used in Section 251 of the DGCL) contained in this Agreement and approval of the Merger. Unless this Agreement has been duly terminated in accordance with the terms herein (including payment of any termination fees payable under Article VII), the Company shall, subject to the right of the Company Board of Directors to modify its recommendation in a manner adverse to Parent under certain circumstances as specified in Section 5.7(c), take all lawful action to solicit from the Company Stockholders proxies in favor of the proposal to adopt the “agreement of merger” (as such term is used in Section 251 of the DGCL) contained in this Agreement and approve the Merger and shall take all other action necessary or advisable to secure the vote or consent of the Company Stockholders that is required by the rules of Nasdaq or the DGCL. The Company shall keep Parent updated with respect to proxy solicitation results as reasonably requested by Parent. Notwithstanding anything to the contrary contained in this Agreement, the Company, after consultation with Parent, may adjourn or postpone the Company Stockholders Meeting to the extent necessary to ensure that any legally required supplement or amendment to the Proxy Statement is provided to the Company Stockholders or, if as of the time for which the Company Stockholders Meeting is originally scheduled (as set forth in the Proxy Statement), there are insufficient shares of Company Common Stock represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of the Company Stockholders Meeting.

Section 5.7 No Solicitation of Transactions.

(a) The Company shall, and shall cause its Affiliates, Representatives and any other agents to immediately cease any discussions, negotiations or communications with any party or parties with respect to any Competing Transaction. The Company shall notify in writing each party with which the Company has, in the last twelve months, held any discussions, negotiations or communications with respect to a Competing Transaction and that remain in possession of non-public information in respect of the Company that was furnished by or on behalf of the Company and its Affiliates in connection with such discussions to return or destroy all such information in accordance with and subject to the terms of the applicable nondisclosure agreement between the Company and such party.

(b) The Company shall not, nor shall it authorize or permit any Affiliate or Representative of the Company to, (i) solicit, initiate or intentionally encourage the submission of, any Competing Transaction or (ii) participate in any discussions or negotiations regarding, or furnish to any Third Party any information or data with respect to or provide access to the properties, offices, books, records, officers, directors or employees of, or take any other action to knowingly facilitate, induce or encourage the making of any proposal that constitutes, or may reasonably be expected to lead to, any Competing Transaction. Notwithstanding the foregoing, if, prior to obtaining the Company Required Vote, (i) the Company has complied with this Section 5.7, and (ii) the Company Board of Directors reasonably determines in good faith that a Competing Transaction constitutes or would reasonably be expected to lead to a Superior Competing Transaction, then, to the extent required by the fiduciary obligations of the Company Board of Directors, as determined in good faith by a majority thereof after consultation with the Company’s outside counsel, the Company may, subject to the Company’s providing prior written notice to Parent of its decision to take such action and compliance by the Company with Section 5.7(d), furnish information with respect to the Company to, and participate in discussions and negotiations directly or through its Representatives with, such Third Party, subject to a confidentiality agreement not materially less favorable to the Company than the Confidentiality Agreement.

(c) Neither the Company Board of Directors nor any committee thereof shall (i) withdraw or modify, or propose or resolve to withdraw or modify, in a manner adverse to Parent or Merger Sub, the approval and recommendation by the Company Board of Directors of the Merger, this Agreement and the “agreement of merger” (as such term is used in Section 251 of the DGCL) contained herein, the Transaction Documents, the transactions contemplated hereby and thereby and the actions taken in connection herewith and therewith, (ii) approve or recommend, or propose or resolve to approve or recommend, any Competing Transaction, (iii) approve or recommend, or propose or resolve to approve or recommend, or execute or enter into, any Acquisition Agreement, (iv) approve or recommend, or propose or resolve to approve or recommend, or execute or enter into, any written agreement requiring it to abandon, terminate or fail to consummate the Merger, this Agreement, any Transaction Document or the transactions contemplated hereby or thereby, (v) take any action necessary to render the provisions of any Antitakeover Law inapplicable to any Competing Transaction, or (vi) propose or agree to do any of the foregoing constituting or related to, or that is intended to lead to, any Competing Transaction. Notwithstanding the foregoing, prior to obtaining the Company Required Vote, in response to a Superior Competing Transaction that was not solicited, initiated, intentionally encouraged, participated in or otherwise facilitated by the Company in breach of Section 5.7(b), the Company Board of Directors may, if it determines in good faith (after consultation with the Company’s outside legal counsel) that the failure to do so would result in a breach of the fiduciary duties of the Company Board of Directors to the Company Stockholders under applicable Law or Order, (1) modify, or propose or resolve to modify, in a manner adverse to Parent or Merger Sub, the approvals and recommendations of the Company Board of Directors of the Merger, or the transactions contemplated hereby or by the Transaction Documents, or (2) terminate the Agreement in accordance with Section 7.1(d).

(d) The Company shall notify Parent promptly (but in no event later than thirty-six (36) hours) after it obtains Knowledge of the receipt by the Company (or any of its Representatives) of any Competing Transaction, or of any inquiry that would reasonably be

expected to lead to a Competing Transaction. In such notice, the Company shall identify the Third Party making, and details of the material terms and conditions of, any such Competing Transaction. The Company shall keep Parent fully informed, on a current basis, of the status and material terms of any such Competing Transaction, including any material amendments or proposed amendments as to price and other material terms thereof. The Company shall provide Parent with at least forty-eight (48) hours prior notice of any meeting of the Company Board of Directors (or such lesser notice as is provided to the members of the Company Board of Directors) at which the Company Board of Directors is reasonably expected to consider any Competing Transaction. The Company shall promptly provide Parent with a list of any non-public information concerning the Company’s business, present or future performance, financial condition or results of operations, provided in connection with any such Competing Transaction, and, to the extent such information has not been previously provided to Parent, copies of such information

(e) Notwithstanding anything to the contrary set forth in Section 5.7(d), the Company Board of Directors shall prior to recommending, approving or consummating a Superior Competing Transaction, give Parent the opportunity to meet with the Company and its outside counsel and Company Financial Advisor for the purpose of enabling Parent, on the one hand, and the Company, on the other hand, to negotiate in good faith to make such adjustments in the terms and conditions of this Agreement so that such Competing Transaction ceases to constitute a Superior Competing Transaction.

(f) Nothing contained in this Section 5.7 or any other provision hereof shall prohibit the Company or the Company Board of Directors from taking and disclosing to the Company Stockholders pursuant to Rules 14d-9 and 14e-2 promulgated under the Exchange Act a position with respect to a tender or exchange offer by a Third Party that is consistent with its obligations hereunder; provided, however, that neither the Company nor the Company Board of Directors may either, except as provided by Section 5.7(c), (i) modify, or propose publicly to modify, in a manner adverse to Parent and Merger Sub, the approvals or recommendations of the Company Board of Directors of the Merger or this Agreement and the “agreement of merger” (as such term is used in Section 251 of the DGCL) contained herein, or (ii) approve or recommend a Competing Transaction, or propose publicly to approve or recommend a Competing Transaction.

(g) Nothing in this Section 5.7 shall permit the Company to terminate this Agreement (except as expressly provided in Article VII).

Section 5.8 Public Announcements. The Company and Parent shall consult with each other before issuing any press release or otherwise making any public statements with respect to this Agreement or any of the transactions contemplated by the Transaction Documents and shall not issue any such press release or make any such public statement without the prior consent of the other party, which consent shall not be unreasonably withheld or delayed; provided, however, that a party may, without the prior consent of the other party, issue such press release or make such public statement as may be required by Law or Order or the applicable rules of Nasdaq or NYSE, as applicable, or any listing agreement if it has used its commercially reasonable efforts to consult with the other party and to obtain such party’s consent but has been unable to do so prior to the time such press release or public statement is so required to be issued or made.

Section 5.9 Litigation. Each of Parent, Merger Sub, the LLC and the Company agrees to use its commercially reasonable efforts to defend any lawsuits or other legal proceedings, whether judicial or administrative, challenging, or seeking damages or other relief as a result of, the Merger, this Agreement or the transactions contemplated by the Transaction Documents, including seeking to have any Order adversely affecting the ability of the parties to consummate the transactions contemplated by the Transaction Documents entered by any court or other Governmental Entity promptly vacated or reversed.

Section 5.10 Employee Benefit Matters.

(a) From and after the Effective Time, Parent shall cause the Surviving Corporation to honor and provide for payment of all accrued obligations and benefits existing as of the Effective Time under all Company Benefit Plans and set forth, and identified as such, in the Company Disclosure Letter (including, without limitation, employment or severance agreements between the Company and Persons who are or had been of the Company at or prior to the Effective Time), all in accordance with their respective terms and shall provide the employees of the Company who remain employed immediately after the Effective Time with types and levels of compensation and benefits that are commensurate in all material respects with the compensation and benefits provided to similarly situated employees of Parent.

(b) As soon as reasonably practicable after the Effective Time, Parent shall transfer all eligible assets and Liabilities from the defined contribution retirement plan that Company maintained immediately prior to the Effective Time, to a qualified defined contribution retirement plan maintained by Parent, with respect to the Company Employees in connection with the transactions contemplated by this Agreement. Any such transfer shall be in an amount sufficient to satisfy Section 414(l) of the Code.

(c) With respect to any Parent Employee Benefit Plan in which any Company Employees will participate effective as of the Effective Time, Parent shall, or shall cause the Interim Surviving Corporation or the Final Surviving Entity, as the case may be, to, recognize all service of the Company Employees with the Company or any of its Subsidiaries, as the case may be, for vesting and eligibility purposes (but not for (i) purposes of early retirement subsidies under any Parent Employee Benefit Plan that is a defined benefit pension plan or (ii) benefit accrual purposes, except for vacation, if applicable) in any Parent Employee Benefit Plan in which such Company Employees may be eligible to participate after the Effective Time; provided, that, such service shall not be recognized to the extent that (x) such recognition would result in a duplication of benefits or (y) such service was not recognized under the corresponding Company Benefit Plan. All eligibility waiting periods and evidence of insurability requirements under any Parent Benefit Plan that is a group health plan shall be waived with respect to such Company Employees and their eligible dependents, in each case, to the same extent as service with the Company was taken into account under the comparable Company Benefit Plan, and credit shall be provided for any co-payments, deductibles and offsets (or similar payments) made under Company Benefit Plans for the applicable plan year prior to the Effective Time for purposes of satisfying any applicable deductible, out-of-pocket or similar requirements under any Parent Benefit Plans in which they become eligible to participate after the Effective Time.

(d) This Section 5.10 shall be binding upon and inure solely to the benefit of each of the parties to this Agreement, and nothing in this Section 5.10, express or implied, is intended to confer upon any other Person any rights or remedies of any nature whatsoever under or by reason of this Section 5.10. Nothing contained herein, express or implied (i) shall be construed to establish, amend or modify any benefit plan, program, agreement or arrangement or (ii) shall alter or limit the ability of the Final Surviving Entity, the Interim Surviving Corporation, Parent or any of their respective Affiliates to amend, modify or terminate any benefit plan, program, agreement or arrangement at any time assumed, established, sponsored or maintained by any of them. The parties hereto acknowledge and agree that the terms set forth in this Section 5.10 shall not create any right in any Company Employee or any other Person to any continued employment with the Final Surviving Entity, the Interim Surviving Corporation, Parent or any of their respective Subsidiaries. Notwithstanding anything in this Agreement to the contrary, from and after the Effective Time, the Interim Surviving Corporation or the Final Surviving Entity, as the case may be, will have sole discretion over the hiring, promotion, retention, firing and other terms and conditions of the employment of the employees of the Interim Surviving Corporation or the Final Surviving Entity, as applicable.

(e) With respect to matters described in this Section 5.10, the Company will not send any written notices or other written communication materials to Company Employees without the prior written consent of Parent.

Section 5.11 Directors’ and Officers’ Indemnification and Insurance.

(a) From and after the Effective Time, the Interim Surviving Corporation, and from and after the LLC Effective Time, the Final Surviving Entity, shall indemnify and hold harmless all past and present officers and directors of the Company to the same extent and in the same manner such persons are indemnified as of the date of this Agreement by the Company pursuant to any indemnification agreements between the Company and its directors and officers as of the date hereof, and, to the extent applicable, the DGCL, the LLC Act, the Company Certificate of Incorporation, the Company By-laws, the Certificate of Formation and the Limited Liability Company Agreement of the Final Surviving Entity for acts or omissions occurring at or prior to the Effective Time or the LLC Effective Time, as the case may be, and the Parent shall guarantee such performance by the Interim Surviving Corporation and the Final Surviving Entity. The Certificate of Incorporation and the By-laws of the Interim Surviving Corporation, and the Certificate of Formation and the Limited Liability Company Agreement of the Final Surviving Entity will contain provisions with respect to exculpation and indemnification that are at least as favorable to the indemnified parties as those contained in the Company Certificate of Incorporation and the Company By-laws as in effect on the date hereof, which provisions will not be amended, repealed or otherwise modified for a period of not less than six years from the Effective Time in any manner that would adversely affect the rights thereunder of individuals who, immediately prior to the Effective Time, were directors, officers, employees or agents of the Company, unless such a modification is required by Law.

(b) For a period of six years from the Effective Time, Parent shall cause the Interim Surviving Corporation and the Final Surviving Entity, as the case may be, to maintain in effect (or Parent may instead elect to maintain pursuant to Parent’s policy or policies) for the benefit of the Company’s current directors and officers an insurance and indemnification policy

that provides coverage for acts or omissions occurring prior to the Effective Time that is substantially equivalent to the Company’s existing policy on terms with respect to coverage in the aggregate no less favorable than those of such policy in effect on the date hereof, or, if substantially equivalent insurance coverage is unavailable, the best available coverage; provided, however, that in lieu of the foregoing, prior to the Effective Time, Parent may request that the Company obtain, and upon such request the Company agrees to obtain, in consultation with Parent, “tail” insurance policies as of the Effective Time with a claims period of six years from the Effective Time with at least the same coverage and amounts and containing terms and conditions that are not less advantageous to the Company’s current directors and officers.

(c) This Section 5.11 shall survive the consummation of the Merger, is intended to benefit the Company, the Interim Surviving Corporation and each indemnified party, shall be binding on all successors and assigns of the Interim Surviving Corporation and Parent, and shall be enforceable by the indemnified parties. The provisions of this Section 5.11 are intended to be for the benefit of, and will be enforceable by, each indemnified party, his or her heirs, and his or her representatives and are in addition to, and not in substitution for, any other rights to indemnification or contribution that any such Person may have by contract or otherwise.

Section 5.12 Exchange Matters. Parent shall use its reasonable efforts to authorize for listing on NYSE the shares of Parent Common Stock issuable pursuant to the Merger, and Parent and the Company shall give all notices and make all filings with the NYSE and Nasdaq required in connection with the transactions contemplated herein.

Section 5.13 Treatment as Reorganization. Each of the Company, Parent, Merger Sub and LLC shall use its reasonable best efforts to cause the Integrated Merger to qualify as a reorganization under Section 368(a) of the Code, including by not taking any action that such party knows is reasonably likely to prevent such qualification. To the extent permitted by applicable Tax laws, each of the Company, Parent, Merger Sub and LLC will report the Integrated Merger and the other transactions contemplated by this Agreement in a manner consistent with the treatment of the Integrated Merger as a reorganization under Section 368(a) of the Code.

Section 5.14 Section 16 Matters.

(a) Prior to the Effective Time, the Company shall take all such steps as may be required to cause any dispositions of Common Shares resulting from the transactions contemplated by this Agreement by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Company to be exempt under Rule 16b-3 promulgated under the Exchange Act.

(b) Prior to the Effective Time, Parent shall take all such steps as may be required to cause any acquisitions of Parent Common Stock resulting from the transactions contemplated by this Agreement by each individual who may be subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to Parent to be exempt under Rule 16b-3 promulgated under the Exchange Act.

Section 5.15 Further Assurances.

(a) At and after the Effective Time, the officers and directors of the Interim Surviving Corporation shall be authorized to execute and deliver, in the name and on behalf of the Company or Merger Sub, any deeds, bills of sale, assignments or assurances and to take and do, in the name and on behalf of the Company or Merger Sub, any other actions and things to vest, perfect or confirm of record or otherwise in the Interim Surviving Corporation any and all right, title and interest in, to and under any of the rights, properties or assets of the Company acquired or to be acquired by the Interim Surviving Corporation as a result of, or in connection with, the Merger.

(b) At and after the LLC Effective Time, the officers and directors of the Final Surviving Entity shall be authorized to execute and deliver, in the name and on behalf of the Interim Surviving Corporation or the LLC, any deeds, bills of sale, assignments or assurances and to take and do, in the name and on behalf of the Interim Surviving Corporation or the LLC, any other actions and things to vest, perfect or confirm of record or otherwise in the Final Surviving Entity any and all right, title and interest in, to and under any of the rights, properties or assets of the Interim Surviving Corporation acquired or to be acquired by the Final Surviving Entity as a result of, or in connection with, the LLC Merger.
