THIS AGREEMENT AND PLAN OF MERGER (this “Agreement”) is made and entered into as of August 24, 2017, by and among: REGENXBIO INC., a Delaware corporation (“Parent”); XXXXX XXXXXXX ACQUISITION CORPORATION, a Delaware corporation and a direct, wholly-owned subsidiary of Parent (“Merger Sub”); and DIMENSION THERAPEUTICS, INC., a Delaware corporation (the “Company”). Certain capitalized terms used in this Agreement are defined in Exhibit A.

RECITALS

The Board of Directors of the Company (the “Company Board”) has unanimously (i) determined that it is in the best interests of the Company and the holders of shares of the Company’s common stock, $0.0001 par value per share (the “Shares”), to enter into this Agreement providing for, among other things, the merger of Merger Sub with and into the Company (the “Merger”), with the Company continuing as a wholly-owned Subsidiary of Parent in accordance with the DGCL, (ii) approved and declared the advisability of this Agreement and the Contemplated Transactions in accordance with the DGCL and (iii) adopted a resolution recommending that this Agreement and the Contemplated Transactions be approved and adopted by the holders of Shares.

The respective Boards of Directors of Parent (the “Parent Board”) and Merger Sub (the “Merger Sub Board”) have each unanimously: (i) determined that it is in the best interests of Parent or Merger Sub, as applicable, and their respective stockholders, and declared it advisable, to enter into this Agreement; and (ii) approved the execution, delivery, and performance of this Agreement and the consummation of the Contemplated Transactions, in each case, in accordance with the DGCL.

As a condition and inducement to the willingness of Parent to enter into this Agreement, certain stockholders of the Company have entered into the voting agreement attached hereto as Exhibit B (the “Voting Agreement”) simultaneously with the execution and delivery of this Agreement.

For U.S. federal income Tax purposes, Parent, Merger Sub and the Company intend that the Merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code, that this Agreement will constitute a “plan of reorganization” within the meaning of Treasury Regulation Section 1.368-2(g), and that Parent, Merger Sub and the Company will each be a “party to the reorganization” within the meaning of Section 368(b) of the Code.

AGREEMENT

The parties to this Agreement, intending to be legally bound, agree as follows:

Article I

MERGER TRANSACTION

Section 1.1 Merger of Merger Sub into the Company.

(a) Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with the DGCL, Merger Sub shall be merged with and into the Company at the Effective Time. Following the Effective Time, the separate corporate existence of Merger Sub shall cease, and the Company shall be the surviving corporation in the Merger (with respect to all post-Closing periods, the “Surviving Corporation”) and shall succeed to and assume all the rights and obligations of Merger Sub in accordance with this Agreement and the applicable provisions of the DGCL.

(b) The consummation of the Merger (the “Closing”) shall take place at the offices of Xxxxxxx Procter LLP, 000 Xxxxxxxx Xxxxxx, Xxxxxx, XX 00000, at 9:00 a.m. local time no later than the second business day

following the day on which the last to be satisfied of the conditions set forth in Article VII (other than those conditions that by their nature must be satisfied or waived at the Closing, but subject to the fulfillment or waiver of such conditions) shall be satisfied or waived in accordance with this Agreement, or at such other place, time and date as the parties hereto shall agree. The date on which the Closing occurs is referred to as the “Closing Date”.

(c) Subject to the provisions of this Agreement, contemporaneous with the Closing, the parties hereto shall cause the Merger to be consummated by filing with the Secretary of State of the State of Delaware a certificate of merger with respect to the Merger (the “Certificate of Merger”), executed in accordance with the relevant provisions of the DGCL and shall promptly make all other filings or recordings required under the DGCL with respect to the Merger. The Merger shall become effective at such time as the Certificate of Merger is duly filed with the Secretary of State of the State of Delaware, or at such later time or date as Parent and the Company shall agree and specify in the Certificate of Merger (the time at which the Merger becomes effective, the “Effective Time”).

Section 1.2 Organizational Documents; Directors and Officers of the Surviving Corporation.

(a) At the Effective Time, by virtue of the Merger, the certificate of incorporation of the Surviving Corporation shall be amended and restated in its entirety to be the same as the certificate of incorporation of Merger Sub, as in effect immediately prior to the Effective Time, except that such certificate of incorporation shall (i) be amended to change the name of the Surviving Corporation to “Dimension Therapeutics, Inc.” and (ii) comply with Section 6.4. Thereafter, the certificate of incorporation of the Surviving Corporation may only be amended in accordance with its terms, Section 6.4 and as provided by Law.

(b) At the Effective Time, by virtue of the Merger, the bylaws of Merger Sub as in effect immediately prior to the Effective Time shall be the bylaws of the Surviving Corporation (except that (i) all references to Merger Sub in the bylaws of the Surviving Corporation shall be amended to refer to “Dimension Therapeutics, Inc.” and (ii) such bylaws shall comply with Section 6.4). Thereafter, the bylaws of the Surviving Corporation may only be amended or repealed in accordance with their terms and the certificate of incorporation of the Surviving Corporation, Section 6.4 and as provided by Law.

(c) The Company shall cause to be delivered to Parent, at the Closing, resignations of all the directors of the Company to be effective upon the Effective Time. At the Effective Time, the directors and officers of Merger Sub shall be appointed as the directors and officers, respectively, of the Surviving Corporation, and such directors and officers shall hold office in accordance with and subject to the certificate of incorporation and bylaws of the Surviving Corporation and the DGCL.

Article II

CONVERSION OF SHARES AND DELIVERY OF MERGER CONSIDERATION

Section 2.1 Conversion of Capital Stock. At the Effective Time, as a result of the Merger and without any action on the part of the Company, Parent, Merger Sub or the holder of any capital stock of Parent, Merger Sub or the Company:

(a) Each share of Parent Common Stock issued and outstanding immediately prior to the Effective Time shall remain issued and outstanding and shall not be affected by the Merger.

(b) All Shares that are owned by the Company, Parent or Merger Sub (other than Shares held in trust accounts, managed accounts and the like, or otherwise held in a fiduciary or agency capacity, that are beneficially owned by Third Parties) shall be cancelled and shall cease to exist and no stock of Parent or other consideration shall be delivered in exchange therefor.

(c) Except as provided in Section 2.1(b), each Share issued and outstanding immediately prior to the Effective Time, and subject to Section 2.1(e) and Section 2.2, shall automatically be converted into the right to receive 0.1573 shares of Parent Common Stock (such number of shares of Parent Common Stock, the “Exchange Ratio”), subject to adjustment as provided in Section 2.1(f) (the “Merger Consideration”), without interest, but subject to any withholding required under applicable Tax Law, plus the right, if any, to receive pursuant to Section 2.7, cash in lieu of fractional shares of Parent Common Stock into which such Shares would have been converted pursuant to this Section 2.1(c) (the “Fractional Share Consideration”).

(d) Each share of common stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and become one newly issued, fully paid, and non-assessable share of common stock, par value $0.0001 per share, of the Surviving Corporation and shall constitute the only outstanding shares of capital stock of the Surviving Corporation outstanding at the Effective Time. From and after the Effective Time, all certificates representing shares of Merger Sub Common Stock shall be deemed for all purposes to represent the number of shares of common stock of the Surviving Corporation into which they were converted in accordance with the immediately preceding sentence.

(e) All of the Shares converted into the right to receive the Merger Consideration pursuant to this Article II shall no longer be outstanding and shall automatically be cancelled and shall cease to exist as of the Effective Time, and each certificate previously representing any such Shares (each, a “Certificate”) or any book-entry share registered in the transfer books of the Company (each, a “Book-Entry Share”) shall thereafter represent only the right to receive the Merger Consideration and any applicable Fractional Share Consideration, as well as any dividends to which holders of Shares become entitled in accordance with Section 2.2(e).

(f) If, between the date of this Agreement and the Effective Time, the outstanding shares of Parent Common Stock shall have been increased, decreased, changed into or exchanged for a different number or kind of shares or securities as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split, or other similar change in capitalization, an appropriate and proportionate adjustment shall be made to the Exchange Ratio.

(g) Notwithstanding anything to the contrary contained in this Agreement, the Company acknowledges and agrees that Parent shall not under any circumstances have any obligation to issue, and the Company shall not agree to cause Parent or any of its Affiliates to issue (including by means of the Company issuing Shares prior to the Effective Time) equity securities of any kind (including shares of Parent Common Stock) to MTS Health Partners, L.P., its Affiliates or any other broker, finder, financial advisor or investment banker retained by the Company or any of its Affiliates in connection with the Contemplated Transactions.

Section 2.2 Exchange of Shares.

(a) Exchange Agent. Prior to the Effective Time, Parent shall appoint a bank or trust company reasonably satisfactory to the Company to act as exchange agent (the “Exchange Agent”) for the payment and delivery of the Merger Consideration and the Fractional Share Consideration, as provided in Section 2.1(c), Section 2.2 and Section 2.7. On or before the Effective Time, Parent shall deposit, or cause to be deposited, with the Exchange Agent (i) the shares of Parent Common Stock sufficient to pay the Merger Consideration and (ii) cash in immediately available funds in an amount sufficient to pay the Fractional Share Consideration and any dividends then payable under Section 2.2(e) (such shares of Parent Common Stock and cash amounts, the “Aggregate Merger Consideration,” and such Aggregate Merger Consideration as deposited with the Exchange Agent, the “Exchange Fund”), in each case, for the benefit of the holders of Shares and shares of Company Restricted Stock. Parent shall cause the Exchange Agent to make, and the Exchange Agent shall make delivery of the Merger Consideration, payment of the Fractional Share Consideration and any amounts payable in respect of dividends or other distributions on shares of Parent Common Stock in accordance with Section 2.2(e) out of the Exchange Fund in accordance with this Agreement. The Exchange Fund shall not be used for any other purpose. In the event the Exchange Fund shall be insufficient to make the payments of the Fractional Share Consideration

and any amounts payable in respect of dividends or other distributions on shares of Parent Common Stock in accordance with Section 2.2(e), Parent shall promptly deposit, or cause to be deposited, additional funds with the Exchange Agent in an amount which is equal to the deficiency in the amount required to make such payments, without interest.

(b) Transfer Books. At the Effective Time, the share transfer books of the Company shall be closed, and thereafter there shall be no further registration of transfers of Shares. From and after the Effective Time, Persons who held Shares immediately prior to the Effective Time shall cease to have rights with respect to such Shares, except as otherwise provided for herein. On or after the Effective Time, any Certificates presented to the Exchange Agent or the Surviving Corporation for any reason shall be exchanged for the Merger Consideration with respect to the Shares formerly represented thereby.

(c) Exchange Procedures. As promptly as practicable following the Effective Time (but in no event later than two business days thereafter), Parent shall cause the Exchange Agent to mail to each holder of record of a Certificate or Certificates that immediately prior to the Effective Time represented outstanding Shares whose shares were converted into the right to receive the Merger Consideration pursuant to Section 2.1(c): (i) a letter of transmittal (a “Letter of Transmittal”) which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass to the Exchange Agent only upon proper delivery of the Certificates (or affidavits of loss in lieu thereof) to the Exchange Agent, which Letter of Transmittal shall be in such form and have such other customary provisions as Parent and the Company shall reasonably specify, and (ii) instructions for use in effecting the surrender of the Certificates (or affidavits of loss in lieu thereof) in exchange for the Merger Consideration into which the number of Shares previously represented by such Certificate shall have been converted pursuant to this Agreement, together with any amounts payable in respect of the Fractional Share Consideration in accordance with Section 2.7 and dividends or other distributions on shares of Parent Common Stock in accordance with Section 2.2(e). Upon surrender of a Certificate (or affidavit of loss in lieu thereof) to the Exchange Agent, or to such other agent or agents reasonably satisfactory to the Company as may be appointed by Parent, together with such Letter of Transmittal duly completed and validly executed in accordance with the instructions thereto, and such other documents as may reasonably be required by the Exchange Agent or such other agent or agents, the holder of such Certificate shall be entitled to receive in exchange therefor the Merger Consideration payable in respect of the Shares previously represented by such Certificate pursuant to the provisions of this Article II, plus any Fractional Share Consideration that such holder has the right to receive pursuant to the provisions of Section 2.7 and any amounts that such holder then has the right to receive in respect of dividends or other distributions on shares of Parent Common Stock in accordance with Section 2.2(e) to be mailed or delivered by wire transfer, within two business days following the later to occur of (A) the Effective Time or (B) the Exchange Agent’s receipt of such Certificate (or affidavit of loss in lieu thereof), and the Certificate so surrendered shall be forthwith cancelled. The Exchange Agent shall accept such Certificates (or affidavits of loss in lieu thereof) upon compliance with such reasonable terms and conditions as the Exchange Agent may impose to effect an orderly exchange thereof in accordance with customary exchange practices. In the event of a transfer of ownership of Shares that is not registered in the transfer records of the Company, payment may be made to a Person other than the Person in whose name the Certificate so surrendered is registered, if such Certificate shall be properly endorsed or otherwise be in proper form for transfer, or any Book-Entry Share shall be properly transferred, and the Person requesting such payment shall pay any transfer or other Taxes required by reason of the payment to a Person other than the registered holder of such Certificate or Book-Entry Share or establish to the reasonable satisfaction of Parent that such Tax has been paid or is not applicable. Until surrendered as contemplated by this Section 2.2, each Certificate shall be deemed, at any time after the Effective Time, to represent only the right to receive, upon such surrender, the Merger Consideration as contemplated by this Article II. No interest shall be paid or accrue on any amount payable upon surrender of any Certificate or in respect of Book-Entry Shares or on the Merger Consideration or the Fractional Share Consideration payable upon the surrender of the Certificates or Book-Entry Shares or on any distributions to which holders of such Certificates or Book-Entry Shares are entitled pursuant to Section 2.2(e).

(d) Book-Entry Shares. Except as otherwise required by the Exchange Agent, any holder of Book-Entry Shares shall not be required to deliver a Certificate or an executed Letter of Transmittal to the Exchange Agent to receive the Merger Consideration (or any amounts payable in respect of the Fractional Share Consideration in accordance with Section 2.1(c) or distribution to which such holder is entitled pursuant to Section 2.2(e)) that such holder is entitled to receive pursuant to this Article II. In lieu thereof, each registered holder of one or more Book-Entry Shares shall automatically upon the Effective Time be entitled to receive, and Parent shall cause the Exchange Agent to pay and deliver as soon as reasonably practicable after the Effective Time (but in no event more than two business days thereafter), the Merger Consideration, together with any amounts payable in respect of the Fractional Share Consideration in accordance with Section 2.1(c) and any distribution to which such holder is then entitled pursuant to Section 2.2(e) (less required withholdings as provided in Section 2.4) for each Book-Entry Share. Payment of the Merger Consideration, Fractional Share Consideration and distributions with respect to Book-Entry Shares shall only be made to the person in whose name such Book-Entry Shares are registered.

(e) Dividends with Respect to Parent Common Stock. No dividends or other distributions with respect to Parent Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Parent Common Stock issuable hereunder, and all such dividends and other distributions shall be paid by Parent to the Exchange Agent and shall be included in the Exchange Fund, in each case until the surrender of such Certificate (or affidavit of loss in lieu thereof) in accordance with this Agreement. Following surrender of any such Certificate (or affidavit of loss in lieu thereof) there shall be paid to the holder thereof in addition to the other amounts payable hereunder (i) promptly after the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Parent Common Stock to which such holder is entitled pursuant to this Agreement and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and with a payment date subsequent to such surrender payable with respect to such whole shares of Parent Common Stock.

(f) Termination of Exchange Fund. Any portion of the Exchange Fund (including any Fractional Share Consideration, any applicable dividends or other distributions with respect to Parent Common Stock and any interest and other income received with respect thereto) which remains undistributed to the former holders of Shares on the first anniversary of the Effective Time shall be delivered to Parent, upon demand, and any former holders of Shares who have not theretofore received any Merger Consideration to which they are entitled under this Article II shall thereafter look only to Parent for payment of their claims with respect thereto.

(g) No Liability. None of Parent, Merger Sub, the Company, the Surviving Corporation or the Exchange Agent, or any employee, officer, director, agent or Affiliate of any of them, shall be liable to any holder of Shares in respect of 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 Shares immediately prior to the time at which such amounts would otherwise escheat to, or become property of, any Governmental Body shall, to the extent permitted by applicable Law, become the property of Parent, free and clear of any claims or interest of any such holders or their successors, assigns or personal representatives previously entitled thereto.

(h) Investment of Exchange Fund. The Exchange Agent shall invest any cash included in the Exchange Fund as directed by Parent or, after the Effective Time, the Surviving Corporation; provided, however, that (i) no such investment shall relieve Parent or the Exchange Agent from making the payments required by this Article II and, to the extent that there are losses with respect to such investments, or the Exchange Fund diminishes for other reasons below the level required to make prompt payments of the amounts required by this Article II, Parent shall promptly replace or restore the portion of the Exchange Fund lost through investments or other events, without interest, so as to ensure that the Exchange Fund is, at all times, maintained at a level sufficient to make such payments, (ii) no such investment shall have maturities that could prevent or delay payments to be made pursuant to this Agreement, and (iii) such investments shall be in short-term obligations of the United States of America with maturities of no more than 30 days or guaranteed by the United States of America and

backed by the full faith and credit of the United States of America. Any net profit resulting from, or interest or income produced by, such investments, shall be property of, and paid to, Parent.

Section 2.3 Company Options; Company Restricted Stock. Unless otherwise expressly provided, all of the provisions of this Section 2.3 shall be effectuated without any action on the part of the holder of any Company Option or Company Restricted Stock.

(a) Treatment of Company Options. At the Effective Time, each Company Option which is outstanding immediately prior to the Effective Time (whether or not then vested or exercisable) shall be assumed by Parent and, subject to this Section 2.3(a) and Section 2.3(c), shall otherwise continue to have, and be subject to, the same terms and conditions as were applicable immediately prior to the Effective Time as set forth in the applicable Company Equity Plan (including any applicable award agreement, other agreement or other document evidencing such Company Option) immediately prior to the Effective Time, except that, from and after the Effective Time, (i) each such Company Option will be exercisable for that number of whole shares of Parent Common Stock equal to the product (rounded down to the nearest whole number) of (x) the number of Shares subject to such Company Option as of immediately prior to the Effective Time and (y) the Exchange Ratio, and (ii) the per share exercise price for the shares of Parent Common Stock issuable upon exercise of such assumed Company Option will be equal to the quotient (rounded up to the nearest whole cent) determined by dividing (x) the exercise price of each Share at which such assumed Company Option was exercisable immediately prior to the Effective Time by (y) the Exchange Ratio. Notwithstanding the foregoing, or anything to the contrary set forth in this Section 2.3, the assumption of any Company Options by Parent shall be subject to and accomplished in accordance with the requirements of Treasury Regulations Section 1.409A-1(b)(5)(v)(D).

(b) Company Restricted Stock. At the Effective Time, each share of Company Restricted Stock that is outstanding immediately prior thereto shall thereafter be assumed by Parent and, subject to this Section 2.3(b) and Section 2.3(c), shall otherwise continue to have, and be subject to, the same terms and conditions as were applicable immediately prior to the Effective Time as set forth in the applicable Company Equity Plan (including any applicable award agreement, other agreement or other document evidencing such Company Restricted Stock) immediately prior to the Effective Time, except that, from and after the Effective Time, each such share of Company Restricted Stock shall be converted automatically into that number of whole shares of Parent Common Stock equal to the product (rounded down to the nearest whole number) of (i) the number of shares of Company Restricted Stock as of immediately prior to the Effective Time and (ii) the Exchange Ratio.

(c) Termination of Employment. In the event the employment or other service relationship of a holder of an Assumed Company Award is terminated by Parent or the Surviving Corporation (or any Subsidiary thereof) without Cause or such holder resigns from Parent or the Surviving Corporation (or any Subsidiary thereof) for Good Reason, in either case during the 12-month period following the Effective Time, then any Assumed Company Awards held by such person immediately prior to such termination shall immediately vest in full and become fully exercisable, as applicable, at the time of such termination. For purposes of this Section 2.3(c), “Cause” shall mean, in each case, as determined by Parent in good faith: (i) conduct by the person constituting a material act of misconduct in connection with the performance of the person’s duties, including, without limitation, misappropriation of funds or property of the Parent or the Surviving Corporation (or any Subsidiary thereof) other than the occasional, customary and de minimis use of property for personal purposes; (ii) commission by the person of any felony or any misdemeanor involving moral turpitude, deceit, dishonesty or fraud; (iii) a material breach by the person of any of the provisions contained in any agreement between the person (on the one hand) and Parent or the Surviving Corporation (or any Subsidiary thereof) (on the other hand) which has continued for more than 30 days following written notice of such non-performance; or (iv) failure to reasonably cooperate with a bona fide internal investigation or an investigation by regulatory or law enforcement authorities, after being instructed by Parent or the Surviving Corporation (or any Subsidiary thereof) to cooperate, or the willful destruction or failure to preserve documents or other materials known to be relevant to such investigation or the inducement of others to fail to reasonably cooperate or to produce documents or other materials in connection with such investigation. For purposes of this Section 2.3(c), “Good Reason” shall mean,

in each case, as determined by Parent in good faith, that the person has complied with the “Good Reason Process” (hereinafter defined) following the occurrence of any of the following events without the person’s express written consent: (i) a material diminution in the person’s responsibilities, authority or duties as compared to such person’s responsibilities, authority or duties as of immediately prior to the Effective Time (provided, however, that the consummation of the Contemplated Transactions, and the Acquired Corporations’ status as subsidiaries of Parent on and after the Effective Time, shall not constitute or result in a material diminution in the responsibilities, authority or duties of any holder of Assumed Company Awards subject to this Section 2.3); (ii) a material diminution in the person’s base salary in effect as of immediately prior to the Effective Time, except for across-the-board salary reductions similarly affecting all or substantially all similarly-situated employees; (iii) the material breach by Parent or the Surviving Corporation (or any Subsidiary thereof) of any agreement between the person (on the one hand) and Parent or the Surviving Corporation (or any Subsidiary thereof) (on the other hand) relating to (x) any grant, award or issuance by Parent or the Surviving Corporation (or any Subsidiary thereof) of any equity or debt securities to the person (including any stock option or restricted stock awards) or (y) indemnification of the person by Parent or the Surviving Corporation (or any Subsidiary thereof); or (iv) the relocation of the person’s principal place of employment by more than 50 miles from the location of the person’s principal place of employment immediately prior to the Effective Time. For purposes of this Section 2.3(c), “Good Reason Process” shall mean that (i) the person reasonably determines in good faith that a Good Reason condition has occurred; (ii) the person notifies Parent or the Surviving Corporation (or any Subsidiary thereof) in writing of the first occurrence of the Good Reason condition within 60 days of the first occurrence of such condition; (iii) the person cooperates in good faith with the efforts of Parent or the Surviving Corporation (or any Subsidiary thereof), for a period not less than 30 days following such notice (the “Cure Period”) to remedy the condition; (iv) notwithstanding such efforts, the Good Reason condition continues to exist; and (v) the person terminates his employment within 60 days after the end of the Cure Period.

Each of the Company Employee Plans is and has been operated in all material respects in compliance with its terms and all applicable Law, including ERISA and the Code, except where the failure to operate such Company Employee Plans in accordance with their terms and applicable Law did not and could not, individually or in the aggregate, result in any material liability to the Acquired Corporations. For the last three years, no litigation or governmental administrative proceeding, audit or other Legal Proceeding (other than those relating to routine claims for benefits) is pending or, to the Knowledge of the Acquired Corporations, threatened in writing with respect to any Company Employee Plan, and, to the Knowledge of the Acquired Corporation, there is no reasonable basis for any such litigation or Legal Proceeding, except as would not result in any material liability to any Acquired Corporation.

No payments on account of the Contemplated Transactions would cause any material liability to an Acquired Corporation under Section 409A of the Code.

(h) Except as set forth in Part 3.14(h) of the Company Disclosure Schedule, neither the execution and delivery of this Agreement, the Company Stockholder Approval of this Agreement, nor the consummation of the Contemplated Transactions could (either alone or in conjunction with any other event) (i) result in, or cause the accelerated vesting payment, funding or delivery of, or increase the amount or value of, any payment or benefit to any employee, officer, director or other service provider of the Acquired Corporation; (ii) limit the right of the Acquired Corporation to amend, merge or terminate any Company Employee Plan or related trust; (iii) result in any “parachute payment” as defined in Section 280G(b)(2) of the Code (whether or not such payment is considered to be reasonable compensation for services rendered); or (iv) result in a requirement to pay any tax “gross-up” or similar “make-whole” payments to any employee, director or consultant of the Acquired Corporation.

(i) the Company (in such role, the “Target Party,” and the other party (i.e., Parent) in such role, the “Other Party”) shall not, nor shall the Target Party permit any of its Subsidiaries to, nor shall the Target Party authorize or permit any of its Representatives or any of its Subsidiary’s Representatives to, directly or indirectly (other than with respect to Parent and Merger Sub), (A) solicit, initiate, knowingly facilitate or knowingly encourage any inquiries, proposals or offers that constitute, or that could reasonably be expected to lead to, an Acquisition Proposal, (B) engage in, continue or otherwise participate in any discussions or negotiations with any Third Party, or furnish to any Third Party information or provide to any Third Party access to the businesses, properties, assets or personnel of

(b) Notwithstanding anything to the contrary contained in this Agreement, if, at any time on or after the date hereof but prior to obtaining the Company Stockholder Approval, (i) the Target Party receives an unsolicited written bona fide Acquisition Proposal from a Third Party, (ii) such Acquisition Proposal did not result from a material breach of this Section 5.3 or Section 5.4 and (iii) the Company Board (such board of directors (or any committee thereof) in such role, the “Target Board”), determines in good faith, after consultation with its financial advisor and outside legal counsel, that such Acquisition Proposal constitutes, or could reasonably be expected to lead to, a Superior Proposal and that failure to take such actions would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law, then the Target Party may (A) furnish information and data with respect to the Target Party and its Subsidiaries to the Third Party making such Acquisition Proposal and afford such Third Party access to the businesses, properties, assets and personnel of the Target Party and its Subsidiaries and (B) enter into, maintain and participate in discussions or negotiations with the Third Party making such Acquisition Proposal regarding such Acquisition Proposal or otherwise cooperate with or assist or participate in, or facilitate, any such discussions or negotiations (including by entering into a customary confidentiality agreement with such Third Party for the purpose of receiving non-public information relating to such Third Party); provided, however, that the Target Party (1) will not, and will not permit its Subsidiaries or its or their Representatives to, furnish any non-public information except pursuant to an Acceptable Confidentiality Agreement and (2) will promptly (and in any event within 24 hours) provide to the Other Party any material non-public information concerning the Target Party or its Subsidiaries provided to such Third Party, which was not previously provided to the Other Party. Notwithstanding anything to the contrary contained in this Agreement, the Target Party and its Representatives may (x) following the receipt of an unsolicited written bona fide Acquisition Proposal from a Third Party, contact such Third Party in order to clarify and understand the terms and conditions of such Acquisition Proposal solely in order to permit the Target Board to determine whether such Acquisition Proposal constitutes, or could reasonably be expected to lead to, a Superior Proposal in accordance with this Section 5.3 and (y) direct any Persons to this Agreement, including the specific provisions of this Section 5.3.

(c) The Target Party shall as promptly as practicable (and in any event within 24 hours) notify the Other Party of the Target Party’s receipt of any Acquisition Proposal (or any inquiry, proposal or offer that would reasonably be expected to lead to an Acquisition Proposal), which notification shall include a copy of the applicable written Acquisition Proposal, inquiry, proposal or offer (or, if oral, the material terms and conditions of such Acquisition Proposal, inquiry, proposal or offer) and the identity of the Third Party making such Acquisition Proposal, inquiry, proposal or offer. The Target Party shall thereafter keep the Other Party reasonably informed on a reasonably current basis of the status of any material developments, discussions or negotiations regarding any such Acquisition Proposal, and the material terms and conditions thereof (including

any change in price or form of consideration or other material amendment thereto), including by providing a copy of material documentation relating thereto that is exchanged between the Third Party (or its Representatives) making such Acquisition Proposal and the Target Party (or its Representatives) within 24 hours after receipt thereof.

(d) The Company agrees not to release or permit the release of any Person from, or to waive or permit the waiver or termination of any provision of, any standstill or similar agreement to which the Company or any of its Subsidiaries is a party, or any restrictions on “business combinations” or any similar provision contained in any applicable Takeover Statute or the Company Charter Documents, other than to the extent the Company Board determines in good faith, after consultation with outside legal counsel, that failure to provide such waiver, release or termination would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law.

(e) The Company agrees in the event any Subsidiary or any Representative of the Company takes any action which, if taken by the Company, would constitute a material breach of this Section 5.3, the Company shall be deemed in breach of this Section 5.3.

Section 5.4 Adverse Recommendation Change.

(a) Subject to Section 5.4(b) and Section 5.4(c), the Company Board shall not effect a Company Adverse Recommendation Change.

(b) (i) Notwithstanding anything in this Agreement to the contrary, including Section 5.4(a), at any time prior to obtaining the Company Stockholder Approval, the Target Board may, if it determines in good faith (after consultation with its financial advisor and outside legal counsel), that the failure to do so would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law, (A) make a Company Adverse Recommendation Change in response to either (1) an Acquisition Proposal that the Target Board determines in good faith (after consultation with its financial advisor and outside legal counsel) constitutes a Superior Proposal or (2) an Intervening Event or (B) cause the Target Party to terminate this Agreement pursuant to Section 8.4(a), and authorize the Target Party to enter into a definitive agreement concerning a transaction that constitutes a Superior Proposal (which agreement shall be entered into substantially concurrently with such termination), subject in each case to compliance with the terms of paragraph (ii) or (iii) below, as applicable.

(ii) In the case of a Superior Proposal, (x) no Company Adverse Recommendation Change pursuant to this Section 5.4(b) may be made and (y) no termination of this Agreement pursuant to Section 8.4(a) may be made:

(A) until after the third business day following written notice from the Target Party advising the Other Party that the Target Board intends to make a Company Adverse Recommendation Change or terminate this Agreement pursuant to Section 8.4(a), (a “Notice of Superior Proposal”) and specifying the reasons therefor, including, if applicable, the material terms and conditions of, and the identity of the Third Party making, such Superior Proposal, and a copy of any other relevant transaction documents (it being understood and agreed that any amendment to the financial terms or any other material term of such Superior Proposal shall require a new Notice of Superior Proposal, which shall require a new notice period of two business days, and compliance with this Section 5.4(b) with respect to such new notice);

(B) unless during such three business day period (or two business day period following an amended proposal), the Target Party shall, and shall cause its Representatives to, to the extent requested by the Other Party, negotiate with the Other Party in good faith to make such adjustments to the terms and conditions of this Agreement as would enable the Target Board to maintain the Company Board Recommendation and not make a Company Adverse Recommendation Change or terminate this Agreement pursuant to Section 8.4(a); and

(C) unless, the Target Board determines in good faith, taking into consideration any amendments to this Agreement proposed by the Other Party (after consultation with its financial advisor and outside legal counsel) that the applicable Acquisition Proposal still constitutes a Superior Proposal and that the failure to effect Company Adverse Recommendation Change or terminate this Agreement pursuant to Section 8.4(a) would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law.

(iii) In the case of an Intervening Event, no Company Adverse Recommendation Change pursuant to this Section 5.4(b) may be made:

(A) until after the third business day following written notice from the Target Party advising the Other Party that the Target Board intends to take such action and specifying the material facts underlying the determination by the Target Board that an Intervening Event has occurred, and the reason for the Company Adverse Recommendation Change in reasonable detail (a “Notice of Intervening Event”);

(B) unless during such three business day period, the Target Party shall, and shall cause its Representatives to, to the extent requested by the Other Party, negotiate with the Other Party in good faith to make such adjustments to the terms and conditions of this Agreement in such a manner that obviates the need for a Company Adverse Recommendation Change; and

(C) unless the Target Board determines in good faith, taking into consideration any amendments to this Agreement proposed by the Other Party (after consultation with its financial advisor and outside legal counsel), that the failure to effect a Company Adverse Recommendation Change would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law.

The provisions of this Section 5.4(b)(iii) shall also apply to any material change to the facts and circumstances relating to an Intervening Event, in which case such change shall require a new Notice of Intervening Event and the Target Party shall be required to comply again with the provisions of this Section 5.4(b)(iii), except that any reference to three business days shall instead be to two business days.

(c) Nothing contained in Section 5.3 or this Section 5.4 or elsewhere in this Agreement shall prohibit the Target Board from (i) taking and disclosing a position contemplated by Rule 14d-9, Rule 14e-2(a) or Item 1012(a) of Regulation M-A promulgated under the Exchange Act, (ii) making any disclosure to the Target Party’s stockholders if, in the good faith judgment of the Target Board after consultation with outside legal counsel, the failure to do so would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law or any disclosure requirements under applicable Law, or (iii) making any disclosure that constitutes a stop, look and listen communication or similar communication of the type contemplated by Section 14d-9(f) promulgated under the Exchange Act; provided, however, that this Section 5.4(c) shall not permit the Target Board to make a Company Adverse Recommendation Change except in compliance with Section 5.4(b).

Section 5.5 Preparation of Proxy Statement and Form S-4.

(a) In connection with the Company Stockholders’ Meeting, as soon as reasonably practicable following the date of this Agreement, the Company and Parent shall prepare and Parent shall file with the SEC the Form S-4 (which shall include the Proxy Statement). The Company and Parent shall each use its reasonable best efforts to: (i) cause the Form S-4 to be declared effective under the Securities Act as promptly as practicable after its filing; (ii) ensure that the Form S-4 complies in all material respects with the applicable provisions of the Securities Act and the Exchange Act; and (iii) keep the Form S-4 effective for so long as necessary to complete the Merger. Parent shall notify the Company promptly of the time when the Form S-4 has become effective or any supplement or amendment to the Form S-4 has been filed, and of the issuance of any stop order or

suspension of the qualification of the shares of Parent Common Stock issuable in connection with the Merger for offering or sale in any jurisdiction. The Company shall use its reasonable best efforts to: (A) cause the Proxy Statement to be mailed to the Company’s stockholders as promptly as practicable after the Form S-4 is declared effective under the Securities Act, and (B) ensure that the Proxy Statement complies in all material respects with the applicable provisions of the Securities Act and Exchange Act, including, on or following the date on which the Form S-4 has become effective, the filing by the Company of the definitive Proxy Statement with the SEC on the date on which it is first mailed to the Company’s stockholders. Parent shall also take any other action required to be taken under the Securities Act, the Exchange Act, any applicable foreign or state securities or “blue sky” Laws, and the rules and regulations thereunder in connection with the issuance of Parent Common Stock in the Merger, and the Company shall furnish to Parent all information concerning the Company as may be reasonably requested in connection with any such actions.

(b) Parent and the Company shall furnish to the other party all information concerning such Person and its Affiliates required by the Securities Act or the Exchange Act to be set forth in the Form S-4 or the Proxy Statement. Each of Parent and the Company shall promptly correct any information provided by it for use in the Form S-4 or the Proxy Statement if and to the extent that such information shall have become false or misleading in any material respect. Each of Parent and the Company shall take all steps necessary to amend or supplement the Form S-4 or the Proxy Statement, as applicable, and to cause the Form S-4 or Proxy Statement, as so amended or supplemented, to be filed with the SEC and disseminated to the holders of Shares, in each case as and to the extent required by applicable Law.

(c) Parent and the Company shall promptly provide the other party and their counsel with any comments or other communications, whether written or oral, that Parent or the Company, or their counsel may receive from the SEC or its staff with respect to the Form S-4 or the Proxy Statement promptly after the receipt of such comments. Prior to the filing of the Form S-4 or the Proxy Statement with the SEC (including in each case any amendment or supplement thereto, except with respect to any amendments filed in connection with a Company Adverse Recommendation Change) or the dissemination thereof to the holders of Shares, or responding to any comments of the SEC with respect to the Form S-4 or Proxy Statement, each of Parent and the Company shall provide the other party and their counsel a reasonable opportunity to review and comment on such Form S-4, Proxy Statement, or response (including the proposed final version thereof), and each of Parent and the Company shall give reasonable and good faith consideration to any comments made by the other party or their counsel.

Section 5.6 Company Stockholders’ Meeting. The Company shall take all action necessary to duly call, give notice of, convene, and hold the Company Stockholders’ Meeting as soon as reasonably practicable after the Form S-4 is declared effective, and, in connection therewith, the Company shall mail the Proxy Statement to the holders of Shares in advance of such meeting. Except to the extent that the Company Board shall have effected a Company Adverse Recommendation Change as permitted by Section 5.4, the Proxy Statement shall include the Company Board Recommendation. Subject to Section 5.4, the Company shall use reasonable best efforts to: (a) solicit from the holders of Shares proxies in favor of the adoption of this Agreement and approval of the Merger; and (b) take all other actions necessary or advisable to secure the vote or consent of the holders of Shares required by applicable Law to obtain such approval. The Company shall keep Parent and Merger Sub updated with respect to proxy solicitation results as reasonably requested Parent or Merger Sub. Once the Company Stockholders’ Meeting has been called and noticed, the Company shall not postpone or adjourn the Company Stockholders’ Meeting without the consent of Parent (other than: (i) in order to obtain a quorum of its stockholders; or (ii) as reasonably determined by the Company to comply with applicable Law). The Company shall as promptly as reasonably practicable after the date hereof set a record date for the Company Stockholders’ Meeting. If the Company Board makes a Company Adverse Recommendation Change, it will not alter the obligation of the Company to submit the adoption of this Agreement and the approval of the Merger to the holders of Shares at the Company Stockholders’ Meeting to consider and vote upon, unless this Agreement shall have been terminated in accordance with its terms prior to the Company Stockholders’ Meeting. Unless this

Agreement is terminated in accordance with its terms, the Company shall not submit to the vote of its stockholders any Acquisition Proposal.

Section 5.7 Approval by Sole Stockholder of Merger Sub. Promptly following the execution and delivery of this Agreement, Parent, as sole stockholder of Merger Sub, shall adopt this Agreement and approve the Merger, in accordance with the DGCL.

Article VI

ADDITIONAL COVENANTS OF THE PARTIES

Section 6.1 Filings and Approvals.

(a) Without limiting the generality of anything contained in this Section 6.1, the Company and Parent shall cooperate with each other and use (and shall cause their respective Subsidiaries to use) their reasonable best efforts to take or cause to be taken all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under this Agreement and applicable Law to consummate the Contemplated Transactions as soon as reasonably practicable, including preparing and filing as promptly as reasonably practicable all documentation to effect all necessary notices, reports and other filings and to obtain as promptly as practicable all consents, registrations, approvals, permits and authorizations necessary or advisable to be obtained from any Third Party and/or any Governmental Body, including without limitation, if required, under the HSR Act and any other applicable Antitrust Laws, in order to consummate the Contemplated Transactions.

(b) In furtherance and not in limitation of the foregoing, each of the Company and Parent (and their respective Affiliates, if applicable) shall: (i) promptly, but in no event later than five business days after the date of this Agreement, file any and all notices, reports and other documents required to be filed by such party under the HSR Act with respect to the Contemplated Transactions; and shall use reasonable best efforts promptly to cause the expiration or termination of any applicable waiting periods under the HSR Act; (ii) promptly make all filings, and use reasonable best efforts to timely obtain all consents, permits, authorizations, waivers, clearances and approvals, and to cause the expiration or termination of any applicable waiting periods, as may be required under any other applicable Antitrust Laws (to the extent required); (iii) as promptly as reasonably practicable provide such information as may reasonably be requested by the DOJ or the FTC under the HSR Act or by any other Governmental Body in connection with the Contemplated Transactions, as well as any information required to be submitted to comply with, a request for additional information in order to commence or end a statutory waiting period; and (iv) use reasonable best efforts to cause to be taken, on a timely basis, all other actions necessary or appropriate for the purpose of consummating and effectuating the Contemplated Transactions; provided, however, that notwithstanding anything to the contrary in this Agreement, Parent shall not be obligated to sell or dispose of or hold separately (through a trust or otherwise) any assets or businesses of Parent, the Company or any of their respective Subsidiaries. Parent shall pay all applicable filing fees for filings required under this Section 6.1(b).

(c) Without limiting the generality of anything contained in this Section 6.1, each party hereto shall (i) give the other parties prompt notice of the making or commencement of any request, inquiry, investigation, action or Legal Proceeding by or before any Governmental Body with respect to the Contemplated Transactions, (ii) keep the other parties reasonably informed as to the status of any such request, inquiry, investigation, action or Legal Proceeding, (iii) promptly inform the other parties of any communication to or from the FTC, DOJ or any other Governmental Body to the extent regarding the Contemplated Transactions, or regarding any such request, inquiry, investigation, action or Legal Proceeding, and provide a copy of all written communications and (iv) pull and re-file any notice under the HSR Act only if the other parties agree. Subject to applicable Law, in advance and to the extent practicable, each of Parent or Company, as the case may be, will consult the other on all the information relating to Parent or the Company, as the case may be, and any of their respective Subsidiaries

that appear in any filing made with, or written materials submitted to, any Third Party and/or any Governmental Body in connection with the Contemplated Transactions and shall incorporate all comments reasonably proposed by Parent or the Company, as the case may be; provided, however, that if review of any information would be material in connection with any second request (or similar process) such information shall be provided solely to those individuals acting as outside antitrust counsel for the other parties provided that such counsel shall not disclose such information to such other parties and shall enter into a joint defense agreement with the providing party. In addition, except as may be prohibited by any Governmental Body or by any applicable Law, in connection with any such request, inquiry, investigation, action or Legal Proceeding in respect of the Contemplated Transactions, each party hereto will permit authorized Representatives of the other party to be present at each meeting or conference relating to such request, inquiry, investigation, action or Legal Proceeding and to have access to and be consulted in connection with any document, opinion or proposal made or submitted to any Governmental Body in connection with such request, inquiry, investigation, action or Legal Proceeding.

(d) Neither Parent nor Merger Sub shall, nor shall they permit their respective Subsidiaries to, acquire or agree to acquire any rights, assets, business, Person or division thereof (through acquisition, license, joint venture, collaboration or otherwise), if such acquisition, would reasonably be expected to materially increase the risk of not obtaining any applicable clearance, consent, approval or waiver under the HSR Act or other applicable Antitrust Laws with respect to the Contemplated Transactions.

Section 6.2 Employee Compensation and Benefits.

(a) For a period commencing upon the Effective Time and continuing through the first anniversary of the Effective Time (or until termination of employment, if earlier), Parent shall provide to each employee of the Acquired Corporations who continues to be employed by Parent or the Surviving Corporation (or any Subsidiary thereof) following the Effective Time (the “Continuing Employees”) (i) total cash compensation (including base salary or base hourly rate, as applicable, bonus opportunities, other than equity-based compensation and retention benefits) that are at least equal to the cash compensation provided to such Continuing Employees immediately prior to the Effective Time and (ii) retirement benefits and health and welfare benefits (other than pursuant to defined benefit plans or retiree plans) at levels which are, in the aggregate, substantially comparable in the aggregate to those benefits received by such Continuing Employees immediately prior to the Effective Time (or, as determined by Parent in its sole discretion, those benefits as provided by Parent to similarly situated employees of Parent). In addition, (i) notwithstanding the foregoing, the Continuing Employees shall be eligible for severance benefits as set forth in Part 6.2 of the Company Disclosure Schedule and (ii) Parent shall assume and honor the terms of the agreements set forth in Part 6.2 of the Company Disclosure Schedule. Without limiting the foregoing:

(b) With respect to any accrued but unused personal, sick or vacation time to which any Continuing Employee is entitled pursuant to the personal, sick or vacation policies applicable to such Continuing Employee immediately prior to the Effective Time, Parent shall, or shall cause the Surviving Corporation to and instruct its Subsidiaries to, as applicable, assume the liability for such accrued personal, sick or vacation time and allow such Continuing Employee to use such accrued personal, sick or vacation time in accordance with the practice and policies of the applicable Acquired Corporation.

(c) If requested by Parent at least ten business days prior to the Effective Time, the Acquired Corporations shall terminate any and all Company Employee Plans intended to qualify under Section 401(k) of the Code (the “401(k) Plan(s)”), effective not later than the business day immediately preceding the Effective Time. In the event that Parent requests that such 401(k) Plan(s) be terminated, the Acquired Corporations shall provide Parent with evidence that such 401(k) Plan(s) have been terminated pursuant to resolution of the Company Board not later than two business days immediately preceding the Effective Time. Parent shall have no obligation to cause or permit Continuing Employees with outstanding participant loan balances under the 401(k) Plan(s) to roll over their plan loans to Parent’s 401(k) plan.

(d) Prior to the Effective Time, effective not later than the business day immediately preceding the Effective Time, the Company shall terminate the ESPP. No later than four business days immediately preceding the Effective Time, the Company shall provide Parent with evidence that the ESPP has been or, in accordance with the immediately preceding sentence will be, terminated pursuant to resolution of the Company Board.

(e) Parent agrees that all Continuing Employees shall be eligible to continue to participate in the Surviving Corporation’s health and welfare benefit plans to the extent that they were eligible to participate in such plans prior to the Closing; provided, however, that (i) nothing in this Section 6.2 or elsewhere in this Agreement shall limit the right of Parent or the Surviving Corporation to amend or terminate any such health or welfare benefit plan at any time, and (ii) if Parent or the Surviving Corporation terminates any such health or welfare benefit plan, then (upon expiration of any appropriate transition period) Parent shall use reasonable best efforts to cause the Continuing Employees to be eligible to participate in Parent’s health and welfare benefit plans, to substantially the same extent as similarly situated employees of Parent (taking into account job location). To the extent that service is relevant for eligibility, vesting or allowances (including paid time off) under any benefit plan of Parent and/or the Surviving Corporation in which Continuing Employees are eligible to participate, then Parent shall cause such benefit plan to (to the extent that it would not result in any duplication of benefits), for purposes of eligibility, vesting and allowances (including paid time off) but not for purposes of benefit accrual, credit Continuing Employees for service prior to the Effective Time with the Acquired Corporations to the same extent that such service was recognized prior to the Effective Time under the corresponding benefit plan of the Company.

(f) With respect to all employees, the Acquired Corporations shall be responsible for providing any notices required to be given and otherwise complying with the WARN or similar Laws of any jurisdiction relating to any plant closing or mass layoff (or similar triggering event) caused by the Acquired Corporations on or prior to the Effective Time. If Parent determines that an event would trigger WARN obligations (or obligations arising under similar Laws) after the Effective Time, Parent shall be responsible for providing notices to all employees as are required to be provided notice under WARN (or any similar statute or regulation), in a form that is compliant with applicable Law.

(g) Nothing in this Section 6.2 or elsewhere in this Agreement is intended nor shall be construed to (i) be treated as an amendment to any particular employee benefit or retirement plan, including any Company Employee Plan or employee plan of Parent, (ii) prevent Parent from amending or terminating any of its benefit plans in accordance with their terms, (iii) create a right in any employee to employment with Parent, the Surviving Corporation or any other Subsidiary of the Surviving Corporation and the employment of each Continuing Employee shall be “at will” employment or (iv) create any third-party beneficiary rights in any employee of the Acquired Corporations or the Surviving Corporation, any beneficiary or dependent thereof, or any collective bargaining representative thereof or any other Person.

(h) From and after the Closing Date, Parent shall honor, and shall cause the Surviving Corporation and their respective Subsidiaries to honor, in accordance with its terms, (i) each existing (as of the date hereof) employment, change in control, retention or severance agreement between the Company or any of its Subsidiaries and any current or former officer, director or employee of that company, (ii) all obligations in effect as of the Effective Time under any equity-based, bonus or compensation deferral plans, programs or agreements of the Company or its Subsidiaries and (iii) all vested and accrued benefits under any Company Employee Plan, in each case, in a manner not inconsistent with the provisions of this Agreement. Parent acknowledges that the transaction contemplated hereby shall constitute a “change in control” for purposes of each Company Employee Plan that uses such term or a similar term.

(i) Not later than two business days prior to the Closing Date, the Company shall deliver to Parent the information set forth in Part 6.2(i) of the Company Disclosure Schedule.

Section 6.3 Plan of Reorganization.

(a) The Company, Merger Sub and Parent shall use their respective commercially reasonable efforts to cause the Merger to qualify, and agree not to, and not to permit or cause any Affiliate or any Subsidiary to, take any actions or cause any action to be taken that which would reasonably be expected to prevent the Merger from qualifying, as a “reorganization” under Section 368(a) of the Code.

(b) The Company, Merger Sub and Parent shall treat, and shall not take any Tax reporting position inconsistent with the treatment of, the Merger as a “reorganization” within the meaning of Section 368(a) of the Code for U.S. federal, state and other relevant Tax purposes, unless otherwise required pursuant to a “determination” within the meaning of Section 1313(a) of the Code.

(c) The parties shall cooperate and use their commercially reasonable efforts in order for the Company to obtain the opinion of Xxxxxxx Procter LLP, in form and substance reasonably acceptable to Parent, dated as of the Closing (the “Xxxxxxx Opinion”), and Parent to obtain the opinion of Xxxxxxxxx & Xxxxxxx LLP, dated as of the Closing (the “Xxxxxxxxx Opinion”) to the effect that, on the basis of the facts, representations and assumptions set forth or referred to in such opinions, for U.S. federal income Tax purposes, the Merger will constitute a reorganization within the meaning of Section 368(a) of the Code. The issuance of each of the Xxxxxxx Opinion and Xxxxxxxxx Opinion shall be conditioned upon the receipt by each counsel of customary representation letters from each of the Company, on the one hand, and Parent and Merger Sub, on the other hand, in each case, in form and substance reasonably satisfactory to such counsel. Each such representation letter shall be dated on or before the date of such opinion and shall not have been withdrawn or modified in any material respect.

(d) All transfer, documentary, sales, use, stamp, registration and other such Taxes and fees (including any penalties and interest) incurred in connection with this Agreement (collectively, “Transfer Taxes”) shall be paid by the stockholders when due, and the stockholders will, at their own expense, file all necessary Tax Returns and other documentation with respect to all such Transfer Taxes, and, if required by applicable Laws, the Company will, and will cause its Affiliates to, join in the execution of any such Tax Returns and other documentation. The stockholders shall provide the Company and Parent with (i) evidence reasonably satisfactory to the Company and Parent that such Transfer Taxes have been paid by the stockholders and (ii) a clearance certificate or similar documents which may be required by any Tax authority to relieve the Company and Parent of any obligation to withhold any portion of the payments to the stockholders pursuant to this Agreement.

Section 6.4 Indemnification of Officers and Directors.

(a) For six years after the Effective Time, Parent shall, or shall cause the Surviving Corporation to, maintain officers’ and directors’ liability insurance in respect of acts or omissions occurring prior to the Effective Time covering each such Person currently covered by the Company’s officers’ and directors’ liability insurance policy on terms with respect to coverage and amount no less favorable than those of such policy in effect on the date hereof; provided, however, that in satisfying its obligation under this Section 6.4(a), neither Parent nor the Surviving Corporation shall be obligated to pay annual premiums in excess of 300% of the amount per annum the Company paid in its last full fiscal year prior to the date of this Agreement as set forth on Part 6.4(a) of the Company Disclosure Schedule (the “Current Premium”) and if such premiums for such insurance would at any time exceed 300% of the Current Premium, then the Surviving Corporation shall cause to be maintained policies of insurance that, in the Surviving Corporation’s good faith judgment, provide the maximum coverage available at an annual premium not in excess of 300% of the Current Premium. The provisions of the immediately preceding sentence shall be deemed to have been satisfied if prepaid “tail” or “runoff” policies have been obtained by the Company prior to the Effective Time, which policies provide such Persons currently covered by such policies with coverage for an aggregate period of six (6) years with respect to claims arising from facts or events that occurred on or before the Effective Time, including, in respect of the Contemplated Transactions; provided, however, that the amount paid for such prepaid policies does not exceed 300% of the Current

Premium. At Parent’s request, the Company shall obtain such prepaid policies prior to the Effective Time, with such policies to be effective as of the Effective Time. If such prepaid policies have been obtained prior to the Effective Time, the Surviving Corporation shall (and Parent shall cause the Surviving Corporation to) maintain such policies in full force and effect for their full term, and continue to honor the obligations thereunder.

(b) From and after the Effective Time, each of Parent and the Surviving Corporation shall: (i) indemnify and hold harmless each individual who at the Effective Time is, or at any time prior to the Effective Time was, a director or officer of the Company or of a Subsidiary of the Company (each, an “Indemnified Party”) for any and all costs and expenses (including fees and expenses of legal counsel, which shall be advanced as they are incurred, provided that the Indemnified Party shall have made an undertaking to repay such expenses if it is ultimately determined that such Indemnified Party was not entitled to indemnification under this Section 6.4(b)), judgments, fines, penalties or liabilities (including amounts paid in settlements or compromises) imposed upon or reasonably incurred by such Indemnified Party in connection with or arising out of any action, suit or other proceeding (whether civil or criminal, and including any proceeding before any administrative or legislative body or agency) in which such Indemnified Party may be involved or with which he or she may be threatened (regardless of whether as a named party or as a participant other than as a named party, including, without limitation, as a witness) (an “Indemnified Party Proceeding”) (A) by reason of such Indemnified Party’s being or having been such director or officer or an employee or agent of the Company or any Subsidiary of the Company or otherwise in connection with any action taken or not taken at the request of the Company or any Subsidiary of the Company or (B) arising out of such Indemnified Party’s service in connection with any other corporation or organization for which he or she serves or has served as director, officer, employee, agent, trustee or fiduciary at the request of the Company or any Subsidiary of the Company (including in any capacity with respect to any employee benefit plan), in each of clause (A) or (B) whether or not the Indemnified Party continues in such position at the time such Indemnified Party Proceeding is brought or threatened and at, or at any time prior to, the Effective Time (including any Indemnified Party Proceeding relating in whole or in part to the Contemplated Transactions or relating to the enforcement of this provision or any other indemnification or advancement right of any Indemnified Party), to the fullest extent permitted under applicable Law; and (ii) fulfill and honor in all respects the obligations of the Company and its Subsidiaries pursuant to: (x) each indemnification agreement in effect between the Company or any of its Subsidiaries and any Indemnified Party as of the date of this Agreement; and (y) any indemnification provision (including advancement of expenses) and any exculpation provision set forth in the certificate of incorporation or bylaws of the Company as in effect on the date of this Agreement. Parent shall pay all expenses, including reasonable attorneys’ fees, that may be incurred by Indemnified Parties in connection with their enforcement of their rights provided under this Section 6.4. Parent’s and the Surviving Corporation’s obligations under the foregoing clauses (i) and (ii) shall continue in full force and effect for a period of six (6) years from the Effective Time; provided, however, that all rights to indemnification, exculpation and advancement of expenses in respect of any claim asserted or made within such period shall continue until the final disposition of such claim. If Parent or the Surviving Corporation fails to comply with its obligations in this Section 6.4(b) and an Indemnified Party makes a demand or commences a suit which, in either case, results in a final, nonappealable Order that Parent or the Surviving Corporation failed to comply with such obligation, Parent shall pay such Indemnified Party his or her costs and expenses (including reasonable attorney’s fees and disbursements) in connection with such demand or suit, together with interest thereon at the “prime rate” as published in The Wall Street Journal, Eastern Edition, in effect on the date such payment was required to be made through the date of payment (calculated daily on the basis of a year of 360 days and the actual number of days elapsed, without compounding).

(c) If Parent, the Surviving Corporation or any of its successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving Entity of such consolidation or merger or (ii) transfers or conveys all or substantially all of its properties and assets to any Person, then, and in each such case proper provision shall be made so that the successors and assigns of Parent or the Surviving Corporation, as the case may be, shall assume the obligations set forth in this Section 6.4.

(d) The provisions of this Section 6.4 are (i) intended to be for the benefit of, and shall be enforceable by, each Indemnified Party, his or her heirs and his or her representatives and (ii) in addition to, and not in substitution for, any other rights to indemnification or contribution that any such individual may have under any certificate of incorporation or bylaws, by contract or otherwise. The obligations of Parent and the Surviving Corporation under this Section 6.4 shall not be terminated or modified in such a manner as to adversely affect the rights of any Indemnified Party unless (x) such termination or modification is required by applicable Law or (y) the affected Indemnified Party shall have consented in writing to such termination or modification (it being expressly agreed that the Indemnified Parties shall be third party beneficiaries of this Section 6.4).

Section 6.5 Transaction Litigation. The Company shall (a) as promptly as reasonably practicable (and in any event within two business days) notify Parent in writing of any Transaction Litigation and thereafter keep Parent informed on a reasonably current basis with respect to the status thereof (including by promptly furnishing to Parent and its Representatives such information related to such Transaction Litigation as such Persons may reasonably request), (b) give Parent the opportunity to participate in the defense of any Transaction Litigation and (c) not cease to defend, consent to the entry of any judgment, offer to settle, or enter into any settlement with respect to any such Transaction Litigation without the prior written consent of Parent, which such consent shall not be unreasonably withheld, conditioned or delayed. Without otherwise limiting the Indemnified Parties’ rights with regard to the right to counsel, following the Effective Time, the Indemnified Parties shall be entitled to continue to retain Xxxxxxx Procter LLP or such other counsel selected by such Indemnified Parties prior to the Effective Time to defend any Transaction Litigation.

Section 6.6 Disclosure. The initial press release with respect to this Agreement and the transactions contemplated hereby shall be mutually agreed to by Parent and the Company. Thereafter, Parent and the Company shall consult with each other before issuing any press release or making any other public statement, or scheduling a press conference or conference call with investors or analysts, with respect to this Agreement or the Contemplated Transactions and shall not issue any such press release or make any such other public statement without the consent of the other party, which shall not be unreasonably withheld, delayed or conditioned, except as such release or announcement may be required by applicable Law or any requirements of NASDAQ, in which case the party required to make the release or announcement shall consult with the other party about, and allow the other party reasonable time (taking into account the circumstances) to comment on, such release or announcement in advance of such issuance, and the party will consider such comments in good faith; provided, however, that notwithstanding the foregoing, (i) neither the Company nor Parent be obligated to engage in such consultation with respect to communications that are principally directed to employees, customers, partners or vendors so long as such communications are consistent with previous releases, public disclosures or public statements made jointly by the parties (or individually, if approved by the other party) and (ii) neither the Company nor Parent shall be required to consult with the other before issuing any press release or making any other public statement with respect to a Company Adverse Recommendation Change effected in accordance with Section 5.4.

Section 6.7 Takeover Laws; Advice of Changes.

(a) If any Takeover Statute may become, or may purport to be, applicable to the Contemplated Transactions, each of Parent and the Company and the members of its respective board of directors, to the extent permissible under applicable Law, shall grant such approvals and take such actions, in accordance with the terms of this Agreement, as are necessary so that the Contemplated Transactions may be consummated as promptly as practicable, and in any event prior to the End Date, on the terms and conditions contemplated hereby and otherwise, to the extent permissible under applicable Law, act to eliminate the effect of any Takeover Statute on any of the Contemplated Transactions.

(b) Each of the Company and Parent will give prompt notice to the other (and will subsequently keep the other informed on a reasonably current basis of any material developments related to such notice) upon its becoming aware of the occurrence or existence of any fact, event or circumstance that (i) has, (x) with respect to

the Company, had or would reasonably be expected to result in any Company Material Adverse Effect and (y) with respect to Parent or Merger Sub, had or would reasonably be expected to have a Parent Material Adverse Effect or (ii) is reasonably likely to result in any of the conditions set forth in Article VII not being able to be satisfied prior to the End Date.

Section 6.8 Section 16 Matters. Promptly after the date hereof and prior to the Effective Time, the Company shall take all such steps as may be required to cause any dispositions of Shares resulting from the Contemplated Transactions 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, to the extent permitted by applicable Law.

Section 6.9 Confidentiality. Parent and the Company hereby acknowledge and agree to continue to be bound by the letter agreement dated as of June 2, 2017 between Parent and the Company, as amended by that Amendment #1 to Confidentiality Agreement, dated as of July 20, 2017 (the “Confidentiality Agreement”).

Section 6.11 Listing of Parent Common Stock. Parent shall use its reasonable best efforts to cause the shares of Parent Common Stock to be issued as part of the Merger Consideration to be listed on NASDAQ, subject to official notice of issuance.

The parties hereto hereby agree and consent to be subject to the exclusive jurisdiction of the Court of Chancery of the State of Delaware in New Castle County, Delaware (or, if (and only if) the Court of Chancery of the State of Delaware shall be unavailable, any other court of the State of Delaware or, in the case of claims to which the federal courts have exclusive subject matter jurisdiction, any federal court of the United States of America sitting in the State of Delaware) and hereby waive the right to assert the lack of personal or subject matter jurisdiction or improper venue in connection with any such suit, action, or other proceeding.

(b) EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE CONTEMPLATED TRANSACTIONS.

Section 9.6 Specific Performance. The parties agree that irreparable damage would occur and that the parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, except as expressly provided in the following sentence. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches or threatened breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in a court of competent jurisdiction as set forth in Section 9.5 and, in any action for specific performance, each party waives the defense of adequacy of a remedy at law and waives any requirement for the securing or posting of any bond in connection with such remedy, this being in addition to any other remedy to

which they are entitled at law or in equity (subject to the limitations set forth in this Agreement). The parties hereto further agree that (i) by seeking the remedies provided for in this Section 9.6, a party shall not in any respect waive its right to seek any other form of relief that may be available to a party under this Agreement (including monetary damages) for breach of any of the provisions of this Agreement or in the event that this Agreement has been terminated or in the event that the remedies provided for in this Section 9.6 are not available or otherwise are not granted, and (ii) nothing set forth in this Section 9.6 shall require any party hereto to institute any Legal Proceeding for (or limit any party’s right to institute any Legal Proceeding for) specific performance under this Section 9.6 prior or as a condition to exercising any termination right under Article VIII (and pursuing damages after such termination), nor shall the commencement of any Legal Proceeding pursuant to this Section 9.6 or anything set forth in this Section 9.6 restrict or limit any party’s right to terminate this Agreement in accordance with the terms of Article VIII or pursue any other remedies under this Agreement that may be available at any time.

Section 9.7 Assignability. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties hereto, in whole or in part (whether by operation of law or otherwise), without the prior written consent of the other parties, and any attempt to make any such assignment without such consent shall be null and void.

Section 9.8 Third Party Beneficiaries. Notwithstanding anything contained in this Agreement to the contrary, nothing in this Agreement, express or implied, is intended to confer on any Person other than the parties hereto or their respective heirs, successors, executors, administrators and assigns any rights, remedies, obligations or liabilities under or by reason of this Agreement, except for the provisions of Article II concerning payment of the Aggregate Merger Consideration, Section 6.4, and Section 8.5, which provisions shall inure to the benefit of the Persons or entities benefiting therefrom who shall be third-party beneficiaries thereof and who may enforce the covenants contained therein; provided, however, that, prior to the Effective Time, the rights and remedies conferred on the Company’s equity holders pursuant to Article II concerning payment of the Aggregate Merger Consideration may only be enforced by the Company acting on the behalf of the Company’s equity holders (including holders of Company Options and Company Restricted Stock).

Section 9.9 Notices.

B-4

liability to Parent, Merger Sub or any of their Affiliates under this Agreement as a result of any action or inaction by such Holder acting in his or her capacity as director, officer or other fiduciary of the Company.

7. Miscellaneous.

(a) Entire Agreement; Amendments and Waivers. This Agreement supersedes all prior agreements, written or oral, among the parties hereto with respect to the subject matter hereof and contains the entire agreement among the parties with respect to the subject matter hereof.

EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING BETWEEN THE PARTIES HERETO ARISING OUT OF OR RELATING TO THIS AGREEMENT.

(f) Severability. If one or more provisions of this Agreement are held to be unenforceable under applicable law, the parties agree to renegotiate such provision in good faith, in order to maintain the economic position enjoyed by each party as close as possible to that under the provision rendered unenforceable. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (i) such provision shall be excluded from this Agreement, (ii) the balance of the Agreement shall be interpreted as if such provision were so excluded and (iii) the balance of the Agreement shall be enforceable in accordance with its terms.

(g) No Ownership Interest. Nothing contained in this Agreement shall be deemed to vest in Parent or any of its Affiliates any direct or indirect ownership or incidence of ownership of or with respect to any Shares or New Shares.

(h) Specific Performance. The parties hereto agree that irreparable damage would occur in the event any provision of this Agreement was not performed in accordance with the terms hereof or was otherwise breached.

limitation, an injunction or injunctions to prevent and enjoin breaches of the provisions of this Agreement and to enforce specifically the terms and provisions hereof, in any state or federal court in any competent jurisdiction, in addition to any other remedy to which they may be entitled at law or in equity. Any requirements for the securing or posting of any bond with respect to any such remedy are hereby waived.

(i) No Agreement Until Executed. Irrespective of negotiations among the parties or the exchanging of drafts of this Agreement, this Agreement shall not constitute or be deemed to evidence a contract, agreement, arrangement or understanding between the parties hereto unless and until (i) the Company Board has approved, for purposes of any applicable Takeover Statutes, and any applicable provision of the Company Charter Documents, the transactions contemplated by the Merger Agreement, (ii) the Merger Agreement is executed by all parties thereto and (iii) this Agreement is executed by all parties hereto.

(j) Expenses. All costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such costs or expenses, whether or not the Contemplated Transactions are consummated.

(k) Assignment; Third Party Beneficiaries. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties hereto, in whole or in part (whether by operation of law or otherwise), without the prior written consent of the other parties, and any attempt to make any such assignment without such consent shall be null and void. Notwithstanding anything contained in this Agreement to the contrary, nothing in this Agreement, express or implied, is intended to confer on any Person other than the parties hereto or their respective heirs, successors, executors, administrators and assigns any rights, remedies, obligations or liabilities under or by reason of this Agreement.

(l) No Solicitation. Until the Expiration Date, each Holder agrees that it will not, directly or indirectly, take any action or omit to take any action that the Company is not permitted to take or omit to take pursuant to Section 5.3 and Section 5.4 of the Merger Agreement.
