Any interest or other income resulting from investment of the cash portion of the Exchange Fund shall become part of the Exchange Fund.

(b)Payment Procedures.

of immediately prior to the Effective Time, of (A) shares represented by a certificate or certificates that immediately prior to the Effective Time represented shares of Company Common Stock (the “Certificates”) or (B) shares of Company Common Stock represented by book-entry (“Book-Entry Shares”), in each case, which shares were converted into the right to receive the Merger Consideration at the Effective Time, a letter of transmittal (“Letter of Transmittal”) (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Exchange Agent or, in the case of Book-Entry Shares, upon adherence to the procedures set forth in the Letter of Transmittal, and which shall be in a customary form and agreed to by Parent and the Company prior to the Closing) and instructions for use in effecting the surrender of the Certificates or, in the case of Book-Entry Shares, the surrender of such shares, for payment of the Merger Consideration set forth inSection 3.1(b)(i).

(ii) Upon surrender to the Exchange Agent of a Certificate or Book-Entry Shares, together with the Letter of Transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other customary documents as may be reasonably required by the Exchange Agent, the holder of such Certificate or Book-Entry Shares shall be entitled to receive in exchange therefor (A) one or more shares of Parent Common Stock (which shall be in uncertificated book-entry form unless a physical certificate is requested by such holder) representing, in the aggregate, the whole number of shares of Parent Common Stock, if any, that such holder has the right to receive pursuant toSection 3.1 (after taking into account all shares of Company Common Stock then held by such holder) and (B) a check in the amount equal to the cash payable in lieu of any fractional shares of Parent Common Stock pursuant toSection 3.3(h) and dividends and other distributions pursuant toSection 3.3(g). No interest shall be paid or accrued for the benefit of holders of the Certificates or Book-Entry Shares on the Merger Consideration payable in respect of the Certificates or Book-Entry Shares. If payment of the Merger Consideration is to be made to a Person other than the record holder of such shares of Company Common Stock, it shall be a condition of payment that shares so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer and that the Person requesting such payment shall have paid any transfer and other Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of such shares surrendered or shall have established to the satisfaction of Parent that such Taxes either have been paid or are not applicable. Until surrendered as contemplated by thisSection 3.3(b)(ii), each Certificate and each Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration payable in respect of such shares of Company Common Stock, cash in lieu of any fractional shares of Parent Common Stock to which such holder is entitled pursuant toSection 3.3(h) and any dividends or other distributions to which such holder is entitled pursuant toSection 3.3(g).

(c)Termination of Rights. All Merger Consideration (including any dividends or other distributions with respect to Parent Common Stock pursuant toSection 3.3(g) and any cash in lieu of fractional shares of Parent Common Stock pursuant toSection 3.3(h)) paid upon the surrender of and in exchange for shares of Company Common Stock in accordance with the terms hereof shall be deemed to have been paid in full satisfaction of all rights pertaining to such Company Common Stock. At the Effective Time, the stock transfer books of the Surviving Corporation shall be closed immediately, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Company Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates or Book-Entry Shares are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged for the Merger Consideration payable in respect of the shares of Company Common Stock previously represented by such Certificates or Book-Entry Shares (other than Certificates or Book-Entry Shares evidencing shares of Company Common Stock described inSection 3.1(b)(iii)), any cash in lieu of fractional shares of Parent Common Stock to which the holders thereof are entitled pursuant toSection 3.3(h) and any dividends or other distributions to which the holders thereof are entitled pursuant toSection 3.3(g), without any interest thereon.

(d)Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the former shareholders of the Company on the one hundred eightieth (180th) day after the Closing Date shall be delivered to Parent, upon demand, and any former common shareholders of the Company who have not theretofore received the Merger Consideration, any cash in lieu of fractional shares of Parent Common Stock to which they are entitled pursuant toSection 3.3(h) and any dividends or other distributions with respect to Parent Common Stock to which they are entitled pursuant toSection 3.3(g), in each case without interest thereon, to which they are entitled under thisArticle III shall thereafter look only to Parent for payment of their claim for such amounts.

(e)No Liability. None of the Surviving Corporation, Parent, Merger Sub or the Exchange Agent shall be liable to any holder of Company Common Stock for any amount of Merger Consideration properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If any Certificate or Book-Entry Share has not been surrendered prior to the time that is immediately prior to the time at which Merger Consideration in respect of such Certificate or Book-Entry Share would otherwise escheat to or become the property of any Governmental Entity, any such shares, cash, dividends or distributions in respect of such Certificate or Book-Entry Share shall, to the extent permitted by applicable Law, become the property of Parent, free and clear of all claims or interest of any Person previously entitled thereto.

(f)Lost, Stolen, or Destroyed Certificates. If any Certificate (other than a Certificate evidencing shares of Company Common Stock described inSection 3.1(b)(iii)) 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 reasonably required by the Surviving Corporation, the posting by such Person of a bond in such reasonable amount as the Surviving Corporation may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration payable in respect of the shares of Company Common Stock formerly represented by such Certificate, any cash in lieu of fractional shares of Parent Common Stock to which the holders thereof are entitled pursuant toSection 3.3(h) and any dividends or other distributions to which the holders thereof are entitled pursuant toSection 3.3(g).

(g)Distributions with Respect to Unexchanged Shares of Parent Common Stock. No dividends or other distributions declared or made with respect to shares of Parent Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate or Book-Entry Shares with respect to the whole shares of Parent Common Stock that such holder would be entitled to receive upon surrender of such Certificate or Book-Entry Shares and no cash payment in lieu of fractional shares of Parent Common Stock shall be paid to any such holder, in each case until such holder shall surrender such Certificate or Book-Entry Shares in accordance with thisSection 3.3. Following surrender of any such Certificate or Book-Entry Shares, there shall be paid to such holder of whole shares of Parent Common Stock issuable in exchange therefor, without interest, (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, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but with a subsequent payment date with respect to such whole shares of Parent Common Stock. For purposes of dividends or other distributions in respect of shares of Parent Common Stock, all whole shares of Parent Common Stock to be issued pursuant to the Merger shall be entitled to dividends pursuant to the immediately preceding sentence as if such whole shares of Parent Common Stock were issued and outstanding as of the Effective Time.

(h)No Fractional Shares of Parent Common Stock. No certificates or scrip or shares representing fractional shares of Parent Common Stock shall be issued upon the surrender for exchange of Certificates or Book-Entry Shares and such fractional share interests will not entitle the owner thereof to vote or to have any rights of a stockholder of Parent or a holder of shares of Parent Common Stock.

The Company shall promptly provide all voting tabulation reports relating to the Company Shareholders Meeting that have been prepared by the Company or the Company’s transfer agent, proxy solicitor or other Representative and shall otherwise keep Parent reasonably informed on a reasonably current basis regarding the status of the solicitation and any material oral or written communications from or to the Company’s shareholders with respect thereto. Unless there has been a Company Change of Recommendation as expressly permitted bySection 6.3, the parties agree to cooperate and use their reasonable best efforts to defend against any efforts by any of the Company’s shareholders or any other Person to prevent the Company Shareholder Approval from being obtained.

(b) Parent shall take all action necessary in accordance with applicable Laws and the Organizational Documents of Parent to duly give notice of, convene and hold a meeting of its stockholders for the purpose of obtaining the Parent Stockholder Approval, to be held as promptly as reasonably practicable following the declaration of effectiveness of the Registration Statement and the clearance of the Joint Proxy Statement by the SEC.

written communications from or to Parent’s stockholders with respect thereto. Unless there has been a Parent Change of Recommendation as expressly permitted bySection 6.4, the parties agree to cooperate and use their reasonable best efforts to defend against any efforts by any of Parent’s stockholders or any other Person to prevent the Parent Stockholder Approval from being obtained.

(c) The parties shall cooperate and use their reasonable best efforts to hold the Company Shareholders Meeting and the Parent Stockholders Meeting on the same day and at approximately the same time.

(d) Without limiting the generality of the foregoing but subject to the Company’s ability to terminate this Agreement pursuant toSection 8.1(d), each of the Company and Parent agrees that its obligations to call, give notice of, convene and hold the Company Shareholders Meeting and the Parent Stockholders Meeting, as applicable, pursuant to thisSection 6.6 shall not be affected by the making of a Company Change of Recommendation or a Parent Change of Recommendation, as applicable, and its obligations pursuant to thisSection 6.6 shall not be affected by the commencement, announcement, disclosure, or communication to the Company or Parent, as applicable, of any Company Competing Proposal or Parent Competing Proposal or other proposal (including, a Company Superior Proposal or Parent Superior Proposal) or the occurrence or disclosure of any Company Intervening Event or Parent Intervening Event.

6.7Access to Information.

(a) Subject to applicable Law and the other provisions of thisSection 6.7, the Company and Parent each shall (and shall cause its Subsidiaries to), upon request by the other, furnish the other with all information concerning itself, its Subsidiaries, directors, officers and shareholders/stockholders (as applicable) and such other matters as may be reasonably necessary or advisable in connection with the Registration Statement, the Joint Proxy Statement or any other statement, filing, notice or application made by or on behalf of Parent, the Company or any of their respective Subsidiaries to any third party or any Governmental Entity in connection with the Transactions. Each party shall, and shall cause each of its Subsidiaries to, afford to the other party and its Representatives, during the period prior to the earlier of the Effective Time and the termination of this Agreement pursuant toArticle VIII, reasonable access, at reasonable times upon reasonable prior notice, to the officers, key employees, agents, properties, offices and other facilities of such party and its Subsidiaries and to their books, records, contracts and documents and shall, and shall cause each of its Subsidiaries to, furnish reasonably promptly to the other party and its Representatives such information concerning its and its Subsidiaries’ business, properties, contracts, records and personnel as may be reasonably requested, from time to time, by or on behalf of the other party. Each party and its Representatives shall conduct any such activities in such a manner as not to interfere unreasonably with the business or operations of the other party or its Subsidiaries or otherwise cause any unreasonable interference with the prompt and timely discharge by the employees of the other party and its Subsidiaries of their normal duties. Notwithstanding the foregoing provisions of thisSection 6.7(a), neither party shall be required to, or to cause any of its Subsidiaries to, grant access or furnish information to the other party or any of its Representatives to the extent that such information is subject to an attorney/client privilege or the attorney work product doctrine or that such access or the furnishing of such information is prohibited by applicable Law or an existing contract or agreement (provided,however, the Company or Parent, as applicable, shall inform the other party as to the general nature of what is being withheld and the Company and Parent shall reasonably cooperate to make appropriate substitute arrangements to permit reasonable disclosure that does not suffer from any of the foregoing impediments). Notwithstanding the foregoing, neither party shall have access to personnel records of the other party or any of its Subsidiaries relating to individual performance or evaluation records, medical histories or other information that in the other party’s good faith opinion the disclosure of which could subject the other party or any of its Subsidiaries to risk of liability. Notwithstanding the foregoing, neither party shall be permitted to conduct any sampling or analysis of any environmental media or building materials at any facility of the other party or its Subsidiaries without the prior written consent of the other party, which may be granted or withheld in such other party’s sole discretion. Each party agrees that (i) no investigation or information provided pursuant to thisSection 6.7 shall affect or be deemed to modify any representation or warranty made by the Company, Parent or Merger Sub herein and (ii) it

will not, and will cause its Representatives not to, use any information obtained pursuant to thisSection 6.7(a) for any purpose unrelated to the consummation of the Transactions.

(b) The Confidentiality Agreement dated as of August 4, 2018 between Parent and the Company (as amended from time to time, the “Confidentiality Agreement”) shall survive the execution and delivery of this Agreement and shall apply to all information furnished thereunder or hereunder. All information provided to any party or its Representatives pursuant to or in connection with this Agreement is deemed to be “Confidential Information” as defined under the Confidentiality Agreement.

6.8Regulatory Approvals; Efforts.

(a) Each of the parties shall use reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other party in doing, all things necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the Merger and the other Transactions.

(b) Except for the filings and notifications made pursuant to Antitrust Laws to whichSection 6.8(c) andSection 6.8(d), and not thisSection 6.8(b), shall apply, promptly following the execution of this Agreement, the parties shall proceed to prepare and file with the appropriate Governmental Entities all authorizations, consents, notifications, certifications, registrations, declarations and filings that are necessary in order to consummate the Transactions and shall diligently and expeditiously prosecute, and shall cooperate fully with each other in the prosecution of, such matters. Neither Party nor its Subsidiaries shall agree to any actions, restrictions or conditions with respect to obtaining any consents, registrations, approvals, permits, expirations of waiting periods or authorizations in connection with the Transactions without the prior written consent of the other Party (which consent shall not be unreasonably withheld, conditioned or delayed).

(c) As promptly as reasonably practicable following the execution of this Agreement, but in no event later than ten (10) Business Days following the date of this Agreement, the parties shall make any filings required under the HSR Act. Each of Parent and the Company shall, and shall cause their respective Subsidiaries to, cooperate fully with each other and shall furnish to the other such necessary information and reasonable assistance as the other may reasonably request in connection with its preparation of any filings under any applicable Antitrust Laws. Unless otherwise agreed, Parent and the Company shall each use its reasonable best efforts to ensure the prompt expiration or termination of any applicable waiting period under the HSR Act. Parent and the Company shall each use its reasonable best efforts to respond to and comply with any request for information or documentary material from any Governmental Entity charged with enforcing, applying, administering, or investigating any Antitrust Law, including the Federal Trade Commission, the Antitrust Division of the U.S. Department of Justice, any attorney general of any state of the United States, or any other competition authority of any other jurisdiction (“Antitrust Authority”). Each of Parent and the Company shall, and shall cause their respective Subsidiaries to, in connection with the efforts referenced in this Section 6.8, (i) cooperate in all respects with each other in connection with any investigation or other inquiry, including any proceeding initiated by a private party; (ii) promptly notify the other Party of any communication concerning this Agreement or any of the transactions contemplated hereby to that Party from or with any Governmental Entity, or from any other Person alleging that the consent of such person (or another Person) is or may be required in connection with the Transactions, and consider in good faith the views of the other Party and keep the other Party reasonably informed of the status of matters related to the transactions contemplated by this Agreement, including furnishing the other Party with any written notices or other communications received by such Party from, or given by such Party to, any Governmental Entity and of any communication received or given in connection with any proceeding by a private party, in each case regarding any of the transactions contemplated hereby, except that any materials concerning one Party’s valuation of the other Party may be redacted; and (iii) permit the other Party to review in draft any proposed communication to be submitted by it to any Governmental Entity with reasonable time and opportunity to comment, and consult with each other in advance of anyin-person or telephonic meeting or conference with any Governmental Entity or, in connection with any

proceeding by a private party, with any other Person, and, to the extent permitted by the applicable Governmental Entity or Person, not participate in any meeting or discussion with any Governmental Entity relating to any filings or investigations concerning this Agreement or any of the transactions contemplated hereby unless it consults with the other Party and its Representatives in advance and invites the other Party’s Representatives to attend in accordance with applicable Laws. The parties shall take reasonable efforts to preserve the attorney-client privilege, work product doctrine, joint defense privilege or any other privilege with respect to any information shared pursuant to thisSection 6.8(c).

(d) Notwithstanding anything herein to the contrary, Parent shall take any and all action necessary, including but not limited to (i) selling or otherwise disposing of, or holding separate and agreeing to sell or otherwise dispose of, assets, categories of assets or businesses of the Company or Parent or their respective Subsidiaries; (ii) terminating existing relationships, contractual rights or obligations of the Company or Parent or their respective Subsidiaries; (iii) terminating any venture or other arrangement; (iv) creating any relationship, contractual rights or obligations of the Company or Parent or their respective Subsidiaries or (v) effectuating any other change or restructuring of the Company or Parent or their respective Subsidiaries and, in each case, to enter into agreements or stipulate to the entry of an order or decree or file appropriate applications with any Antitrust Authority in connection with any of the foregoing and in the case of actions by or with respect to the Company or its Subsidiaries or its or their businesses or assets (each, a “Divestiture Action”) to ensure that no Governmental Entity enters any order, decision, judgment, decree, ruling, injunction (preliminary or permanent), or establishes any Law or other action preliminarily or permanently restraining, enjoining or prohibiting the consummation of the Merger, or to ensure that no Antitrust Authority with the authority to clear, authorize or otherwise approve the consummation of the Merger, fails to do so by the End Date;provided,however, that, notwithstanding any other provisions of this Agreement, none of Parent or any of its Subsidiaries shall be required to take or agree to take any Divestiture Action or other action that would reasonably be expected to have, individually or in the aggregate, a material adverse effect on the business, financial condition or operations of Parent and its Subsidiaries (including the Company and its Subsidiaries) from and after the Effective Time, taken as a whole (a “Regulatory Material Adverse Effect”). The Company shall not be required to take any Divestiture Action requested by Parent unless such action is only effective after the Effective Time and conditioned upon the consummation of the Transactions.

(e) In the event that any action is threatened or instituted challenging the Merger as violative of any Antitrust Law, Parent shall take such action, including any Divestiture Action, as may be necessary to avoid, resist or resolve such action (provided, that in no event shall thisSection 6.8(e) require Parent to make or agree to take any Divestiture Action that would reasonably be expected to have, individually or in the aggregate, a Regulatory Material Adverse Effect). Subject to the terms of thisSection 6.8, including the immediately foregoing sentence, in the event that any permanent or preliminary injunction or other order is entered or becomes reasonably foreseeable to be entered in any Proceeding that would make consummation of the Transactions in accordance with the terms of this Agreement unlawful or that would restrain, enjoin or otherwise prevent or materially delay the consummation of the Transactions, Parent shall take promptly any and all steps necessary to vacate, modify or suspend such injunction or order so as to permit such consummation prior to the End Date.

(f) Company, Parent and Merger Sub shall not take any action that could reasonably be expected to hinder or delay obtaining the clearance, or the expiration or termination of the applicable waiting period, under the HSR Act.

6.9Employee Matters.

(a) During the period commencing at the Effective Time and ending on the first anniversary of the Closing Date (the “Continuation Period”), Parent shall, or shall cause the Surviving Corporation or one of its Subsidiaries to, provide each employee of the Company and its Subsidiaries who continues to be employed by Parent or its Subsidiaries (including the Surviving Corporation and its Subsidiaries) immediately following the

Effective Time (collectively, the “Continuing Employees”) with (i) a base salary or base wage rate, as applicable, that is no less favorable than the base salary or base wage rate, as applicable, provided by the Company or its Subsidiaries to such Continuing Employee immediately prior to the Effective Time; (ii) short- and long-term target incentive compensation opportunities that are no less favorable in value, in the aggregate, than the short- and long-term target incentive compensation opportunities provided by the Company or its Subsidiaries to such Continuing Employee immediately prior to the Effective Time;provided that, if the relative allocation of short- and long-term target incentive compensation opportunities as of immediately prior to the Effective Time is adjusted, the fraction of the aggregate target incentive compensation opportunity allocated to short-term incentives shall not be smaller than that applicable to similarly situated employees of Parent and its Subsidiaries;provided,further, in order to address Parent and the Company’s different grant-timing practices, Parent may grant long-term incentive awards at different times of the year than such awards are granted to its employees generally (to prevent Continuing Employees from not receiving full 2019 award opportunities) and may adjust future awards to ensure that there is not a duplication of incentive compensation opportunities with respect to the same performance period (or portion thereof); and (iii) other compensation and employee benefits that are substantially comparable in value, in the aggregate, to those provided by the Company or its Subsidiaries to such Continuing Employee immediately prior to the Effective Time. Without limiting the immediately preceding sentence, Parent shall, or shall cause the Surviving Corporation or one of its Subsidiaries to, provide to each Continuing Employee whose employment terminates during the Continuation Period with severance benefits equal to the greater of (A) the severance benefits for which such Continuing Employee is eligible under the Company’s Change in Control Severance Pay Plan (in accordance with its terms at the Effective Time) and (B) the severance benefits for which similarly situated employees of Parent and its Subsidiaries are eligible, in each case, determined (x) solely for the purpose ofclause (A) above, without taking into account any reduction after the Effective Time in compensation paid to such Continuing Employee and (y) taking into account each Continuing Employee’s service with the Company and its Subsidiaries (and any predecessor entities) and, after the Effective Time, Parent and its Subsidiaries. In addition, for as long as there are adequate assets in the trusts underlying the Retiree Welfare Plans to meet the benefit obligations under the Retiree Welfare Plans, Parent shall, or shall cause the Surviving Corporation or one of its Subsidiaries to continue to, maintain the Retiree Welfare Plans for the benefit of the individuals who are receiving benefits thereunder as of immediately prior to the Effective Time, or would be eligible to receive benefits thereunder as of immediately prior to the Effective Time, based on the plan terms and level of benefits as of immediately prior to the Effective Time.

(b) With respect to any employee benefit plans of Parent or its Subsidiaries in which any Continuing Employees become eligible to participate on or after the Effective Time (the “New Plans”), Parent shall or shall cause the Surviving Corporation or one of its Subsidiaries to: (i) obtain waivers of allpre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to such employees and their eligible dependents under any New Plans, except to the extent suchpre-existing conditions, exclusions or waiting periods would apply under the analogous the Company Benefit Plan, (ii) provide each such employee and his or her eligible dependents with credit for any eligible expenses incurred by such employee or dependent prior to the Effective Time (or, if later, the time that such employee becomes eligible for coverage under a New Plan) under a Company Benefit Plan (to the same extent that such credit was given under the analogous Company Benefit Plan prior to the Effective Time (or, if later, the time that such employee becomes eligible for coverage under a New Plan)) in satisfying any applicable deductible,co-payment orout-of-pocket requirements under any New Plans, and (iii) recognize all service of such employees with the Company and its Subsidiaries for all purposes in any New Plan to the same extent that such service was taken into account under the analogous Company Benefit Plan prior to the Effective Time;provided that the foregoing service recognition shall not apply to the extent it would result in duplication of benefits for the same period of services.

(c) Subject toSection 6.9(d), Parent shall, or shall cause the Surviving Corporation to, assume and honor all Company Benefit Plans in accordance with their terms. Parent hereby acknowledges that a “change in control” (or similar phrase) within the meaning of the Company Benefit Plans will occur at the Effective Time.

(d) Nothing in this Agreement shall confer upon any employee, director or consultant of the Company or any of its Affiliates any right to continue in the employ or service of the Surviving Corporation, the Company, or any Affiliate thereof, or shall interfere with or restrict in any way the rights of the Surviving Corporation, the Company, Parent or any Affiliate thereof to discharge or terminate the services of any employee, director or consultant of the Company or any of its Affiliates at any time for any reason whatsoever, with or without cause. Nothing in this Agreement shall be deemed to (i) establish, amend, or modify any Company Benefit Plan, New Plan or any other benefit or employment plan, program, agreement or arrangement, or (ii) alter or limit the ability of the Surviving Corporation or any of its Affiliates to amend, modify or terminate any particular Company Benefit Plan, New Plan or any other benefit or employment plan, program, agreement or arrangement after the Effective Time. Without limiting the generality of the final sentence ofSection 9.6, nothing in this Agreement, express or implied, is intended to or shall confer upon any person, including, without limitation, any current or former employee, director or consultant of the Company or any of its Affiliates, any third party beneficiary or other right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

6.10Indemnification; Directors’ and Officers’ Insurance.

(a) Without limiting any other rights that any Indemnified Person may have pursuant to any employment agreement or indemnification agreement in effect on the date hereof or otherwise (which shall be assumed by Parent and the Surviving Corporation), from the Effective Time, Parent and the Surviving Corporation shall, jointly and severally, indemnify, defend and hold harmless each Person who is now, or has been at any time prior to the date of this Agreement or who becomes prior to the Effective Time, a director, officer or employee of the Company or any of its Subsidiaries or who acts as a fiduciary under any Company Benefit Plan or any of its Subsidiaries or is or was serving at the request of the Company or any of its Subsidiaries as a director, officer, employee or agent of another corporation, partnership, limited liability company, joint venture, employee benefit plan, trust or other enterprise (the “Indemnified Persons”) against all losses, claims, damages, costs, fines, penalties, expenses (including attorneys’ and other professionals’ fees and expenses), liabilities or judgments or amounts that are paid in settlement, of or incurred in connection with any threatened or actual Proceeding to which such Indemnified Person is a party or is otherwise involved (including as a witness) based, in whole or in part, on or arising, in whole or in part, out of the fact that such Person is or was a director, officer or employee of the Company or any of its Subsidiaries, a fiduciary under any Company Benefit Plan or any of its Subsidiaries or is or was serving at the request of the Company or any of its Subsidiaries as a director, officer, employee or agent of another corporation, partnership, limited liability company, joint venture, employee benefit plan, trust or other enterprise or by reason of anything done or not done by such Person in any such capacity, whether pertaining to any act or omission occurring or existing prior to, at or after the Effective Time and whether asserted or claimed prior to, at or after the Effective Time (“Indemnified Liabilities”), including all Indemnified Liabilities based in whole or in part on, or arising in whole or in part out of, or pertaining to, this Agreement or the Transactions, in each case to the fullest extent permitted under applicable Law (and Parent and the Surviving Corporation shall, jointly and severally, pay expenses incurred in advance of the final disposition of any such Proceeding to each Indemnified Person to the fullest extent permitted under applicable Law and in accordance with the procedures (if any) set forth in the Organizational Documents of the Company or any Subsidiary of the Company; provided, that such Covered Person to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such Covered Person is not entitled to indemnification).

(b) Parent and the Surviving Corporation shall not amend, repeal or otherwise modify any provision in the Organizational Documents of the Surviving Corporation or its Subsidiaries in any manner that would affect (or manage the Surviving Corporation or its Subsidiaries, with the intent to or in a manner that would) adversely the rights thereunder or under the Organizational Documents of the Surviving Corporation or any of its Subsidiaries of any Indemnified Person to indemnification, exculpation and advancement except to the extent required by applicable Law. Parent shall, and shall cause the Surviving Corporation and its Subsidiaries to, fulfill and honor any indemnification, expense advancement or exculpation agreements between the Company or any of its Subsidiaries and any of its directors, officers or employees existing immediately prior to the Effective Time.

(c) To the fullest extent permitted under applicable Law, Parent and the Surviving Corporation shall indemnify any Indemnified Person against all reasonable costs and expenses (including reasonable attorneys’ fees and expenses), such amounts to be payable in advance upon request as provided in thisSection 6.10, relating to the enforcement of such Indemnified Person’s rights under thisSection 6.10 or under any charter, bylaw or contract regardless of whether such Indemnified Person is ultimately determined to be entitled to indemnification hereunder or thereunder.

(d) Parent and the Surviving Corporation will cause to be put in place, and Parent shall fully prepay immediately prior to, and conditioned upon the occurrence of, the Effective Time, “tail” insurance policies with a claims reporting or discovery period of at least six (6) years from the Effective Time from an insurance carrier with the same or better credit rating as the Company’s current insurance carrier with respect to directors’ and officers’ liability insurance companies with terms and conditions no less favorable than the current directors’ and officers’ liability insurance policies maintained by the Company with respect to matters, acts or omissions existing or occurring at or prior to the Effective Time;provided,however, that Parent may elect in its sole discretion to, but shall not be required to, spend more than three hundred percent (300%) (the “Cap Amount”) of the last annual premium paid by the Company prior to the date hereof for the six (6) years of coverage under such “tail” policy;provided,further, that if the cost of such insurance exceeds the Cap Amount, and Parent elects not to spend more than the Cap Amount for such purpose, then Parent shall purchase the greatest coverage available for the six year period for the Cap Amount.

(e) In the event that Parent, the Surviving Corporation or any Subsidiary of the Surviving Corporation, or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, in each such case, proper provisions shall be made so that the successors and assigns of Parent, the Surviving Corporation or such Subsidiary of the Surviving Corporation, as the case may be, shall assume the obligations set forth in thisSection 6.10. Parent and the Surviving Corporation shall not sell, transfer, distribute or otherwise dispose of any of their assets or the assets of any Subsidiary in a manner that would reasonably be expected to render Parent or the Surviving Corporation unable to satisfy their obligations under thisSection 6.10. The provisions of thisSection 6.10 are intended to be for the benefit of, and shall be enforceable by, the parties and each Person entitled to indemnification or insurance coverage or expense advancement pursuant to thisSection 6.10, and his or her heirs and representatives. The rights of the Indemnified Persons under thisSection 6.10 are in addition to any rights such Indemnified Persons may have under the Organizational Documents of the Company or any of its Subsidiaries, or under any applicable contracts or Law. Parent and the Surviving Corporation shall pay all expenses, including attorneys’ fees, that may be incurred by any Indemnified Person in enforcing the indemnity and other obligations provided in thisSection 6.10.

6.11Transaction Litigation. In the event any Proceeding by any Governmental Entity or other Person is commenced or, to the knowledge of the Company or Parent, as applicable, threatened, that questions the validity or legality of the Transactions or seeks damages in connection therewith (“Transaction Litigation”), the parties agree to promptly (and in any event within two (2) Business Days) notify the other party of such Transaction Litigation and shall keep the other party reasonably informed with respect to the status thereof and cooperate and use their reasonable best efforts to defend against and respond thereto. Each Party shall give the other Party a reasonable opportunity to participate in the defense or settlement of any Transaction Litigation against the first Party and shall consider in good faith the other Party’s advice with respect to such Transaction Litigation. Each Party shall not cease to defend, consent to the entry of any judgment, settle or offer to settle or take any other material action with respect to any Transaction Litigation against it without the prior written consent of the other Party (which consent shall not be unreasonably withheld, conditioned or delayed).

6.12Public Announcements. The initial press release with respect to the execution of this Agreement shall be a joint press release to be reasonably agreed upon by the parties. The parties will not, and each of the foregoing will cause its Representatives not to, issue any public announcements or make other public disclosures

regarding this Agreement or the Transactions, without the prior written approval of the parties, except as may be required by Law or by the rules of any stock exchange upon which such party’s or any of its Subsidiaries’ capital stock is traded (in which event such party shall endeavor, on a basis reasonable under the circumstances, to provide an opportunity to the other party to review and comment upon such public announcement or statement in advance and shall give due consideration to all reasonable changes suggested thereto);provided, that each party may issue public announcements or make other public disclosures regarding this Agreement or the Transactions that consist solely of information previously disclosed in press releases or announcements previously approved by either party or made by either party in compliance with thisSection 6.12;provided,further, that neither party shall be (a) restricted from making internal communications with its employees which are not made public or (b) required by any provision of this Agreement to consult with or obtain any approval from any other party with respect to a public announcement or press release issued in connection with the receipt and existence of a Company Competing Proposal or Parent Competing Proposal, as applicable, and matters related thereto or a Company Change of Recommendation or Parent Change of Recommendation other than as set forth inSection 6.3 orSection 6.4, as applicable.

Except with respect to Antitrust Laws as provided inSection 6.8, the Company and Parent shall promptly provide each other (or their respective counsel) copies of all filings made by such party or its Subsidiaries with the SEC or any other Governmental Entity in connection with this Agreement and the Transactions. Without limiting in any way any party’s rights or obligations under this Agreement, nothing contained in this Agreement shall give any party, directly or indirectly, the right to control or direct the other party and their respective Subsidiaries’ operations prior to the Effective Time. Prior to the Effective Time, each of the parties shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its and its Subsidiaries’ respective operations.

6.14Section 16 Matters. Prior to the Effective Time, Parent, Merger Sub and the Company shall take all such steps as may be required to cause any dispositions or acquisitions of equity securities of the Company (including derivative securities) or acquisitions or dispositions of equity securities of Parent (including derivative securities) in connection with this Agreement by each officer or director who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Company, or any officer or director who will become subject to such reporting requirements with respect to Parent, to be exempt pursuant to Rule16b-3 under the Exchange Act.

Each of Parent, Merger Sub, and the Company will (and will cause its respective Subsidiaries to) use its reasonable best efforts to cause the Merger to qualify, and will not take or knowingly fail to take (and will cause its Subsidiaries not to take or knowingly fail to take) any action that would, or would reasonably be expected to, prevent or impede the Merger from qualifying, as a “reorganization” within the meaning of Section 368(a) of the Code. Each of Parent, Merger Sub, and the Company will use its reasonably best efforts and will cooperate in good faith with one another to obtain the opinions of counsel referred to inSection 7.2(d) andSection 7.3(d). In connection therewith, (a) Parent shall deliver to Akin Gump Strauss Hauer & Feld LLP (or another nationally recognized tax counsel reasonably acceptable to the parties) (“Parent Tax Counsel”) and Wachtell, Lipton Rosen & Katz (or another nationally recognized tax counsel reasonably acceptable to the parties) (“Company Tax Counsel”) a duly executed certificate containing such representations, warranties and covenants as shall be reasonably necessary or appropriate to enable such counsel to render the opinions described inSection 7.2(d) andSection 7.3(d) (the “Parent Tax Certificate”) and (b) the Company shall

deliver to Parent Tax Counsel and Company Tax Counsel a duly executed certificate containing such representations, warranties and covenants as shall be reasonably necessary or appropriate to enable such counsel to render the opinions described inSection 7.2(d) andSection 7.3(d) (the “Company Tax Certificate”), in each case dated as of the Closing Date (and, if requested, dated as of the date on which the Registration Statement is declared effective by the SEC), and Parent, Merger Sub, and the Company shall each provide such other information as reasonably requested by each of Parent Tax Counsel and Company Tax Counsel for purposes of rendering the opinions described inSection 7.2(d) andSection 7.3(d), as applicable.

Notwithstanding anything to the contrary herein, (i) any breach by the Company of its obligations under thisSection 6.19 shall not, in and of itself, constitute a breach for purposes ofSection 8.1(c)(B) or give rise to a failure of the condition precedent set forth inSection 7.2(b) to be satisfied and (ii) Parent and Merger Sub each (A) acknowledge and agree that neither the obtaining of financing nor any refinancing of existing Indebtedness by any Person is a condition to the Closing and (B) reaffirm their respective obligations to consummate the Transactions in accordance with the terms of this Agreement irrespective and independently of the availability of any financing or refinancing, subject to the satisfaction or waiver of the conditions set forth inSection 7.1 andSection 7.2.

Each party and its counsel cooperated in the drafting and preparation of this Agreement and the documents referred to herein, and any and all drafts relating thereto exchanged between the parties shall be deemed the work product of the parties and may not be construed against any party by reason of its preparation. Accordingly, any rule of law or any legal decision that would require interpretation of any ambiguities in this Agreement against any party that drafted it is of no application and is hereby expressly waived.

(b) The inclusion of any information in the Company Disclosure Letter or Parent Disclosure Letter shall not be deemed an admission or acknowledgment, in and of itself and solely by virtue of the inclusion of such information in the Company Disclosure Letter or Parent Disclosure Letter, as applicable, that such information is required to be listed in the Company Disclosure Letter or Parent Disclosure Letter, as applicable, that such items are material to the Company and its Subsidiaries, taken as a whole, or Parent and its Subsidiaries, taken as a whole, as the case may be, or that such items have resulted in a Company Material Adverse Effect or a Parent Material Adverse Effect. The headings, if any, of the individual sections of each of the Parent Disclosure Letter and Company Disclosure Letter are inserted for convenience only and shall not be deemed to constitute a part thereof or a part of this Agreement. The Company Disclosure Letter and Parent Disclosure Letter are arranged in sections corresponding to the Sections of this Agreement merely for convenience, and the disclosure

of an item in one section of the Company Disclosure Letter or Parent Disclosure Letter, as applicable, as an exception to a particular representation or warranty shall be deemed adequately disclosed as an exception with respect to all other representations or warranties to the extent that the relevance of such item to such representations or warranties is reasonably apparent, notwithstanding the presence or absence of an appropriate section of the Company Disclosure Letter or Parent Disclosure Letter with respect to such other representations or warranties or an appropriate cross reference thereto, and for purposes ofSchedule 6.1 of this Company Disclosure Letter, any item disclosed in response to any subclause ofSchedule 6.1 shall be deemed to be disclosed in response to each other subclause ofSchedule 6.1 to the extent that the relevance of such item to such subclause is reasonably apparent.

(c) The specification of any dollar amount in the representations and warranties or otherwise in this Agreement or in the Company Disclosure Letter or Parent Disclosure Letter is not intended and shall not be deemed to be an admission or acknowledgment of the materiality of such amounts or items, nor shall the same be used in any dispute or controversy between the parties to determine whether any obligation, item or matter (whether or not described herein or included in any schedule) is or is not material for purposes of this Agreement.

(d) All references in this Agreement to Annexes, Exhibits, Schedules, Articles, Sections, subsections and other subdivisions refer to the corresponding Annexes, Exhibits, Schedules, Articles, Sections, subsections and other subdivisions of this Agreement unless expressly provided otherwise. Titles appearing at the beginning of any Articles, Sections, subsections or other subdivisions of this Agreement are for convenience only, do not constitute any part of such Articles, Sections, subsections or other subdivisions, and shall be disregarded in construing the language contained therein.
