THE MERGER

Section 2.1 Merger. Upon the terms and subject to the conditions of this Agreement, and in accordance with the MGCL and the DLLCA, at the Effective Time, the Company shall be merged with and into Merger Sub, whereupon the separate existence of the Company shall cease, and Merger Sub shall continue under the name “Nationwide Health Properties, LLC” as the surviving entity in the Merger (the “Surviving Entity”) and shall be governed by the laws of the State of Delaware. The Merger shall have the effects specified in the MGCL and the DLLCA.

Section 2.2 Closing.

(a) The closing of the Merger (the “Closing”) shall occur as promptly as practicable (but in no event later than the second (2^nd) Business Day) after all of the conditions set forth in Article VII (other than those conditions that by their terms are required to be satisfied or waived at the Closing, but subject to the satisfaction or waiver of such conditions) shall have

been satisfied or waived by the party entitled to the benefit of the same and, subject to the foregoing, shall take place at such time and on a date to be specified by the parties (the “Closing Date”). The Closing shall take place at the offices of Skadden, Arps, Slate, ▇▇▇▇▇▇▇ & ▇▇▇▇ LLP, ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇, or at such other place as agreed to by the parties hereto.

(b) If (i) Parent has directed or intends to direct the Company or any of the Company Subsidiaries to give notice of prepayment or defeasance of any of the Company’s Indebtedness and the earliest permitted prepayment or defeasance date for any of such Indebtedness falls after the then-scheduled Closing Date or (ii) any regulatory approvals or significant third party consents shall not have been obtained, then on a one-time basis, Parent may, by written notice to the Company at least three (3) Business Days prior to the then scheduled Closing Date, defer the Closing Date until a date no later than the earliest to occur of (x) such earliest permitted prepayment or defeasance date (in the case of clause (i)), (y) thirty (30) days after the previously-scheduled Closing Date, and (z) the Outside Date (such deferred Closing, a “Delayed Closing”). In the event that Parent causes a Delayed Closing as contemplated by this Section 2.2(b), all references in this Agreement to the Closing (except the references in the preceding sentence) shall be deemed references to the Delayed Closing and the Closing Date shall be deemed to occur on the date on which the Delayed Closing occurs.

Section 2.3 Effective Time.

(a) At the Closing, the Company, Parent and Merger Sub shall (i) cause articles of merger with respect to the Merger (the “Articles of Merger”) to be duly executed and filed with the State Department of Assessments and Taxation of Maryland (the “SDAT”) as provided under the MGCL, (ii) cause a certificate of merger with respect to the Merger (the “Certificate of Merger”) to be duly executed and filed with the Delaware Secretary as provided under the DLLCA and (iii) make any other filings, recordings or publications required to be made by the Company or Merger Sub under the MGCL or DLLCA in connection with the Merger. The Merger shall become effective following the close of business on the Closing Date, with such date and time specified in the Articles of Merger and the Certificate of Merger, or on such other date and time, not to exceed thirty-one (31) days from the filing, as shall be agreed to by the Company and Parent and specified in the Articles of Merger, following acceptance for record by SDAT, and the Certificate of Merger, following acceptance by the Delaware Secretary (such date and time being hereinafter referred to as the “Effective Time”).

(b) The Merger shall have the effects set forth in the MGCL, the DLLCA and this Agreement. Without limiting the generality of the foregoing, and subject thereto, from and after the Effective Time, the Surviving Entity shall possess all properties, rights, privileges, powers and franchises of the Company and Merger Sub, and all of the claims, obligations, liabilities, debts and duties of the Company and Merger Sub shall become the claims, obligations, liabilities, debts and duties of the Surviving Entity.

Section 2.4 Organizational Documents. Subject to Section 6.9, at the Effective Time, the certificate of formation and limited liability company agreement of Merger Sub, as in effect immediately prior to the Effective Time, shall be the certificate of formation and limited liability company agreement of the Surviving Entity, until thereafter amended in accordance with applicable Law and the applicable provisions of such certificate of formation and limited liability company agreement.

Section 2.5 Tax Consequences. It is intended that, for U.S. federal income tax purposes, the Merger shall qualify as a reorganization within the meaning of Section 368(a) of the Code, and that this Agreement be, and is hereby adopted as, a plan of reorganization for purposes of Sections 354 and 361 of the Code.

Section 2.6 Transaction Structure. Notwithstanding anything in this Agreement to the contrary, the Company shall, if requested by Parent at least five (5) Business Days prior to the Company Stockholder Meeting, (a) agree to, and cooperate in the implementation of, certain reorganization transactions by the Company prior to the Effective Time, including any transactions that may be necessary to implement a holding company structure for the Company, (b) agree to, and cooperate in the implementation of, any changes to the structure of the transactions contemplated by this Agreement, including (i) changing the direction of the Merger so that the Company is the Surviving Entity, (ii) adding new parties to the Agreement in the event that the holding company structure contemplated by clause (a) is implemented, or (iii) switching to an exchange offer plus back-end merger structure, and (c) cooperate with Parent with respect to any other reasonable changes regarding the structure of the transactions contemplated herein (in the case of each of the foregoing clauses (a) through (c), such cooperation shall include entering into appropriate amendments to this Agreement and the Company Disclosure Letter and seeking a private letter ruling from the IRS with respect to any reorganization by the Company or other change to the structure of the transactions contemplated by this Agreement); provided, however, that such cooperation contemplated by this Section 2.6 shall not (w) have any adverse impact on the Company, (x) alter or change the amount or kind of the consideration to be issued to holders of Company Common Stock, (y) adversely affect the tax consequences of the Merger to holders of Company Common Stock, or (z) materially impede or delay consummation of the Merger.

ARTICLE III

EFFECT OF THE MERGER

Section 3.1 Effect on Shares. At the Effective Time, by virtue of the Merger and without any action on the part of the Company, Parent, Merger Sub or the holder of any securities of the Company, Parent or Merger Sub:

(a) Cancellation of Company Securities. Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time that is held by any wholly owned Company Subsidiary, by Parent or by any Parent Subsidiary shall

automatically be canceled and retired and shall cease to exist, and no payment shall be made with respect thereto.

(b) Conversion of Company Securities. Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than shares to be canceled in accordance with Section 3.1(a)) shall automatically be converted into the right to receive 0.7866 shares (the “Exchange Ratio”) of common stock, par value $0.25 per share (the “Parent Common Stock”), of Parent, subject to adjustment as provided in Section 3.1(d) (the “Merger Consideration”). All shares of Company Common Stock, when so converted, shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and each holder of a certificate (a “Certificate”) or book-entry share registered in the transfer books of the Company (a “Book-Entry Share”) that immediately prior to the Effective Time represented shares of Company Common Stock shall cease to have any rights with respect to such Company Common Stock other than the right to receive the Merger Consideration in accordance with Section 3.2, including the right, if any, to receive, pursuant to Section 3.7, cash in lieu of fractional shares of Parent Common Stock into which such shares of Company Common Stock have been converted pursuant to this Section 3.1(b), together with the amounts, if any, payable pursuant to Section 3.2(d).

(c) Treatment of Merger Sub Membership Interests. All membership interests of Merger Sub (the “Merger Sub Interests”) issued and outstanding immediately prior to the Effective Time shall remain as outstanding membership interests of the Surviving Entity.

(d) Adjustments. Without limiting the other provisions of this Agreement and subject to Section 6.1(b)(ii) and Section 6.1(b)(iii), if at any time during the period between the date of this Agreement and the Effective Time, the Company should split, combine or otherwise reclassify the Company Common Stock, or make a distribution in Company Common Stock, or otherwise change the Company Common Stock into any other securities, then (without limiting any other rights of Parent or Merger Sub hereunder), the Merger Consideration and any Option Payment, Restricted Stock Unit Payment, Restricted Stock Payment and/or Performance Share Payment to be received in the form of Parent Common Stock (each such payment, a “Stock Award Payment”) shall be ratably adjusted to reflect any such change. Without limiting the other provisions of this Agreement and subject to Section 6.2(b)(ii) and Section 6.2(b)(iii), if at any time during the period between the date of this Agreement and the Effective Time, Parent should split, combine or otherwise reclassify the Parent Common Stock, or make a distribution in Parent Common Stock, or otherwise change the Parent Common Stock into other securities, then the Exchange Ratio shall be ratably adjusted to reflect any such change.

Section 3.2 Exchange Fund; Exchange Agent.

(a) 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, the Stock Award Payments

and the Aggregate Cash Consideration, as provided in Section 3.1(b) and Section 3.3. On or before the Effective Time, Parent shall deposit, or cause to be deposited, with the Exchange Agent (i) certificates representing the shares of Parent Common Stock sufficient to pay the Merger Consideration and the Stock Award Payments, and (ii) cash in immediately available funds in an amount sufficient to pay the Aggregate Cash Consideration (such certificates representing 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 of Company Common Stock, Company Options, Company Restricted Stock Units, shares of Company Restricted Stock and Company Performance Shares. In the event the Exchange Fund shall be insufficient to make the payments contemplated by Section 3.3, 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 payment. Parent shall cause the Exchange Agent to make, and the Exchange Agent shall make, payments of the Merger Consideration, amounts in respect of Company Options, Company Restricted Stock Units, shares of Company Restricted Stock and Company Performance Shares and any amounts payable in respect of dividends or distributions on shares of Parent Common Stock in accordance with Section 3.2(d) or otherwise payable pursuant to Section 3.7 out of the Exchange Fund in accordance with this Agreement and the Articles of Merger and the Certificate of Merger. The Exchange Fund shall not be used for any other purpose. Any and all interest earned on cash deposited in the Exchange Fund shall be paid to the Surviving Entity.

(b) Share 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 of Company Common Stock. From and after the Effective Time, persons who held shares of Company Common Stock 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 Entity for any reason shall be exchanged for the Merger Consideration with respect to the shares of Company Common Stock formerly represented thereby.

(i) As promptly as practicable following the Effective Time (but in no event later than two (2) Business Days thereafter), the Surviving Entity shall cause the Exchange Agent to mail (and to make available for collection by hand) (A) to each holder of record of a Certificate (x) 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 only upon proper delivery of the Certificates (or affidavits of loss in lieu thereof) to the Exchange Agent, and which Letter of Transmittal shall be in such form and have such other provisions as the Surviving Entity may reasonably specify, and (y) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration into which the number of shares of Company Common Stock previously represented by such Certificate shall have been converted pursuant to this

Agreement, together with any amounts payable in respect of dividends or distributions on shares of Parent Common Stock in accordance with Section 3.2(d) (which instructions shall provide that, at the election of the surrendering holder, (1) Certificates may be surrendered by hand delivery or otherwise or (2) the Merger Consideration in exchange therefor, together with any amounts payable in respect of dividends or distributions on shares of Parent Common Stock in accordance with Section 3.2(d), may be collected by hand by the surrendering holder or by check or wire transfer to the surrendering holder), (B) to each holder of a Company Option, a certificate representing an option to acquire shares of Parent Common Stock or a check or direct deposit, in each case in an amount due and payable to such holder pursuant to Section 3.3(a) in respect of such Company Option, (C) to each holder of a Company Restricted Stock Unit, a certificate representing a Rollover RSU or a check or direct deposit, in each case in an amount due and payable to such holder pursuant to Section 3.3(b) in respect of such Company Restricted Stock Unit, (D) to each holder of a share of Company Restricted Stock, a certificate representing shares of Parent Common Stock in an amount due and payable to such holder pursuant to Section 3.3(c) in respect of such share of Company Restricted Stock, (E) to each holder of a Company Performance Share, a certificate representing shares of Parent Common Stock in an amount due and payable to such holder pursuant to Section 3.3(d) in respect of such Company Performance Share, and (F) to each holder of a Company DER, the payment due and payable to such holder pursuant to Section 3.3(e).

(ii) Upon surrender of a Certificate (or affidavit of loss in lieu thereof) for cancellation to the Exchange Agent, together with a 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, the holder of such Certificate shall be entitled to receive in exchange therefor the Merger Consideration for each share of Company Common Stock formerly represented by such Certificate pursuant to the provisions of this Article III plus any cash such holder is entitled to receive in lieu of fractional shares of Parent Common Stock that such holder has the right to receive pursuant to the provisions of Section 3.1(b) and any amounts that such holder has the right to receive in respect of dividends or distributions on shares of Parent Common Stock in accordance with Section 3.7, to be mailed, made available for collection by hand or delivered by wire transfer, within two (2) 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 (or affidavit of loss in lieu thereof) so surrendered shall be forthwith canceled. 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 normal exchange practices. Until surrendered as contemplated by this Section 3.2, 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 III. No interest shall be paid or accrued for the benefit of holders of the Certificates on the Merger Consideration payable upon the surrender of the Certificates.

(iii) As promptly as practicable following the Effective Time (but in no event later than two (2) Business Days thereafter), the Surviving Entity shall cause the Exchange Agent (A) to issue to each holder of Book-Entry Shares that number of uncertificated whole shares of Parent Common Stock that such holder is entitled to receive pursuant to Section 3.1(b) in respect of such Book-Entry Shares, and (B) to issue and deliver to each holder of Book-Entry Shares a check or wire transfer for any amounts payable in respect of dividends or distributions on shares of Parent Common Stock in accordance with Section 3.2(d) and any other amount such holder is entitled to receive in lieu of fractional shares of Parent Common Stock that such holder has the right to receive pursuant to the provisions of Section 3.1(b), in each case without such holder being required to deliver a Certificate or an executed Letter of Transmittal to the Exchange Agent, and such Book-Entry Shares shall then be canceled. No interest shall be paid or accrued for the benefit of holders of Book-Entry Shares on the Merger Consideration payable in respect of the Book-Entry Shares.

(iv) In the event of a transfer of ownership of shares of Company Common Stock that is not registered in the transfer records of the Company, it shall be a condition of payment that any Certificate surrendered in accordance with the procedures set forth in this Section 3.2(c) shall be properly endorsed or shall be otherwise in proper form for transfer, or any Book-Entry Share shall be properly transferred, and that the Person requesting such payment shall have paid any Transfer Taxes and other Taxes required by reason of the payment of the Merger Consideration to a person other than the registered holder of the Certificate or Book-Entry Share surrendered or shall have established to the satisfaction of Parent that such Tax either has been paid or is not applicable.

(d) 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.

(e) Termination of Exchange Fund. Any portion of the Exchange Fund (including any interest and other income received with respect thereto) which remains undistributed to the former holders of shares of Company Common Stock on the first (1^st)

anniversary of the Effective Time shall be delivered to Parent, upon demand, and any former holders of shares of Company Common Stock who have not theretofore received any Merger Consideration to which they are entitled under this Article III shall thereafter look only to the Surviving Entity for payment of their claims with respect thereto.

(f) No Liability. None of Parent, Merger Sub, the Company, the Surviving Entity or the Exchange Agent, or any employee, officer, director, agent or Affiliate of any of them, shall be liable to any holder of shares of Company Common Stock 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 Authority shall, to the extent permitted by applicable Law, become the property of the Surviving Entity, free and clear of any claims or interest of any such holders or their successors, assigns or personal representatives previously entitled thereto.

(g) 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 Entity; provided, however, that (i) no such investment shall relieve Parent or the Exchange Agent from making the payments required by this Article III 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 Aggregate Merger Consideration as contemplated hereby, Parent shall promptly replace or restore the portion of the Exchange Fund lost through investments or other events 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 thirty (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, the Surviving Entity.

Section 3.3 Stock Options; Restricted Stock Units; Restricted Stock; Performance Shares; Dividend Equivalent Rights.

(a) Treatment of Stock Options. At the Effective Time, without any action on the part of any holder or the Company, each outstanding Company Option (whether or not then vested or exercisable) shall be vested and exercisable as of the Effective Time and, in the sole discretion of Parent, shall be treated in accordance with either (i) or (ii), except that the Company Options set forth on Section 3.3(a) of the Company Disclosure Letter shall not become fully vested and exercisable and shall be treated in accordance with (ii):

(i) Each outstanding Company Option as of the Effective Time shall thereafter be exchanged for a cash payment by the Parent or the Surviving Entity as promptly as practicable following the Effective Time (but in no event later than three (3) Business Days thereafter) equal to the excess, if any, of (1) the product of (x) the

Exchange Ratio and (y) the VWAP of Parent Common Stock over (2) the exercise price per share of Company Common Stock subject to such Company Option, less any required withholding Taxes (which may be covered by withholding shares) (the “Cash Option Payment”), and the holder of any such Company Option shall cease to have any right thereunder to acquire any equity interest in the Company, Company Subsidiary, Parent, Surviving Entity or any of their Affiliates; or

(ii) Each outstanding Company Option, as of the Effective Time, shall be assumed by Parent, without any action on the part of any holder or the Company, and will otherwise continue to have, and be subject to, the same terms and conditions (after taking into account any acceleration of vesting and exercisability provided in the foregoing provisions of this Section 3.3(a)) as were applicable immediately prior to the Effective Time as set forth in the applicable Company 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, (A) 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 of Company Common Stock subject to such Company Option as of immediately prior to the Effective Time and (y) the Exchange Ratio, and (B) 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 to the nearest whole cent) determined by dividing (x) the exercise price of each share of Company Common Stock at which the assumed Company Options were exercisable immediately prior to the Effective Time by (y) the Exchange Ratio.

Parent shall notify the Company in writing, at least five (5) Business Days prior to the Effective Time regarding whether Company Options shall be treated in accordance with (i) or (ii) of this Section 3.3(a). Amounts payable pursuant to Section 3.3(a)(i) or (ii), as applicable, are referred to herein as the “Option Payment”.

(b) Treatment of Restricted Stock Units.

(i) Each Company Restricted Stock Unit which is outstanding and unvested immediately prior to the Effective Time shall become fully vested and all restrictions with respect thereto shall lapse immediately prior to the Effective Time; provided, however, that the Company Restricted Stock Units listed on Section 3.3(b)(i) of the Company Disclosure Letter shall vest, and their restrictions shall lapse, solely in accordance with their terms; and provided, further, however, that the Company Restricted Stock Units set forth on Section 3.3(b)(ii) of the Company Disclosure Letter (the “Rollover RSUs”) shall not become fully vested and their restrictions shall not fully lapse, and they shall be treated in accordance with Section 3.3(b)(ii) hereof. Each Company Restricted Stock Unit for which vesting accelerates and restrictions lapse at the Effective Time shall be canceled by virtue of the Merger and without any action on the part of any holder of any Company Restricted Stock Unit in consideration for the right

at the Effective Time to receive, as promptly as practicable following the Effective Time (but in no event later than three (3) Business Days thereafter), a cash amount with respect thereto equal to the product of (A) the number of shares of Company Common Stock previously subject to such Company Restricted Stock Unit and (B) the product of (x) the Exchange Ratio and (y) the VWAP of Parent Common Stock, less any required withholding Taxes (which may be covered by withholding shares) (the “Restricted Stock Unit Payment”). As of the Effective Time, all Company Restricted Stock Units (other than Rollover RSUs) shall no longer be outstanding and shall automatically terminate and cease to exist, and each holder of a Company Restricted Stock Unit (other than a Rollover RSU) shall cease to have any rights with respect thereto, except the right to receive the Restricted Stock Unit Payment.

(ii) Each outstanding Rollover RSU, as of the Effective Time, shall be assumed by Parent, without any action on the part of any holder or the Company, and will otherwise continue to have, and be subject to, the same terms and conditions (including vesting terms and conditions) as were applicable immediately prior to the Effective Time as set forth in the applicable Company Plan (including any applicable award agreement, other agreement or the document evidencing such Rollover RSU) immediately prior to the Effective Time, except that, from and after the Effective Time, each Rollover RSU will relate to a number of whole shares of Parent Common Stock equal to the product (rounded down to the nearest whole number) of (A) the number of shares of Company Common Stock subject to such Rollover RSU as of immediately prior to the Effective Time and (B) the Exchange Ratio.

(c) Treatment of Restricted Stock. Each share of Company Restricted Stock which is outstanding immediately prior to the Effective Time shall become fully vested and all restrictions with respect thereto shall lapse immediately prior to the Effective Time, and each such share of Company Restricted Stock shall be converted into a number of shares of Parent Common Stock equal to the Exchange Ratio in accordance with Section 3.1(b) of this Agreement without any action on the part of the holder of any share of Company Restricted Stock (the “Restricted Stock Payment”). As of the Effective Time, each holder of shares of Company Restricted Stock shall cease to have any rights with respect thereto, except the right to receive shares of Parent Common Stock.

(d) Treatment of Performance Shares. With respect to any Company Performance Shares outstanding immediately prior to the Effective Time, the performance period shall terminate immediately prior to the Effective Time and the number of Company Performance Shares subject to the award which shall vest as of the Effective Time shall be determined in accordance with the relevant award agreement based on the Company’s actual performance for the shortened performance period. Each Company Performance Share for which vesting accelerates and restrictions lapse at the Effective Time shall be converted into a number of shares of Parent Common Stock equal to the Exchange Ratio in accordance with

Section 3.1(b) of this Agreement without any action on the part of the holder of any share of Company Performance Shares (the “Performance Share Payment”). Any Company Performance Shares subject to the award which do not vest after giving effect to the first sentence of this Section 3.3(d) shall terminate as of the Effective Time and each holder thereof shall cease to have any rights with respect thereto.

(e) Dividend Equivalent Rights. Any dividend equivalent right granted in connection with another award pursuant to a Company Plan which is outstanding (whether or not vested), immediately prior to the Effective Time, whether denominated in restricted stock units or otherwise (each, a “Company DER”), shall, if unvested, become fully vested immediately prior to the Effective Time and all Company DERs shall be paid in accordance with their terms (any such payment, the “DER Payment”). As of the Effective Time, all Company DERs shall no longer be outstanding and shall automatically terminate and cease to exist, and each holder thereof shall cease to have any rights with respect thereto, except the right to receive the DER Payment.

(f) Company Assumed Awards. As soon as reasonably practicable after the Effective Time, but in no event later than five (5) Business Days following the Effective Time, Parent shall deliver to each holder of any Rollover RSU or Company Option treated in accordance with Section 3.3(a)(ii) (each such Rollover RSU or Company Option, a “Company Assumed Award”) an appropriate notice setting forth such holder’s rights pursuant to such Company Assumed Award. Unless the shares of Parent Common Stock issuable upon exercise or settlement of the Company Assumed Awards are otherwise covered by an existing registration statement on Form S-8 immediately upon the Effective Time, Parent shall prepare and file with the SEC such a registration statement with respect to such shares of Parent Common Stock no later than ten (10) Business Days following the Effective Time and Parent shall exercise reasonable best efforts to maintain the effectiveness of such registration statement for so long as such Company Assumed Awards remain outstanding (subject to blackout periods and similar restrictions in accordance with Parent’s policies). The Company and its counsel shall reasonably cooperate with and assist Parent in the preparation of any such registration statement.

Section 3.4 Withholding Rights. Parent, the Surviving Entity or the Exchange Agent, as applicable, shall be entitled to deduct and withhold from the Merger Consideration and any amounts otherwise payable pursuant to this Agreement to any holder of shares of Company Common Stock, Company Options, Company Restricted Stock Units, shares of Company Restricted Stock, Company Performance Shares and Company DERs, such amounts as Parent, the Surviving Entity or the Exchange Agent is required to deduct and withhold with respect to the making of such payment under the Code, and the rules and regulations promulgated thereunder, or any provision of applicable Tax Law. To the extent that amounts are so deducted or withheld and paid over to the appropriate Governmental Authority by Parent, the Surviving Entity or the Exchange Agent, as applicable, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the person in respect of which such deduction and withholding was made by Parent, the Surviving Entity or the Exchange Agent, as applicable.

Section 3.5 Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, then upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by the Surviving Entity, the posting by such Person of a bond in such reasonable amount as the Surviving Entity may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration to which the holder thereof is entitled pursuant to this Article III.

Section 3.6 Dissenters’ Rights. No dissenters’ or appraisal rights shall be available with respect to the Merger or the other transactions contemplated by this Agreement, so long as the provisions of Section 3-202(c)(1)(ii) of the MGCL are applicable to the transaction.

Section 3.7 Fractional Shares. No certificate or scrip representing fractional shares of Parent Common Stock shall be issued upon the surrender for exchange of Certificates or with respect to Book-Entry Shares, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a stockholder of Parent. Notwithstanding any other provision of this Agreement, each holder of shares of Company Common Stock converted pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of Parent Common Stock shall receive, in lieu thereof, cash, without interest, in an amount equal to such fractional part of a share of Parent Common Stock multiplied by the VWAP of Parent Common Stock.

Section 5.7 SEC Filings; Financial Statements.

(a) Parent has filed with, or furnished (on a publicly available basis) to, the SEC all forms, reports, schedules, statements and documents required to be filed or furnished by it under the Securities Act or the Exchange Act, as the case may be, including any amendments or supplements thereto, from and after January 1, 2009 (collectively, the “Parent SEC Filings”). Each Parent SEC Filing, as amended or supplemented, if applicable, (i) as of its date, or, if amended or supplemented, as of the date of the most recent amendment or supplement thereto, complied in all material respects with the requirements of the Securities Act or the Exchange Act, as the case may be, and the applicable rules and regulations of the SEC thereunder, and (ii) did not, at the time it was filed (or became effective in the case of registration statements), or, if amended or supplemented, as of the date of the most recent amendment or supplement thereto, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading. As of the date of this Agreement, neither Merger Sub nor any other Parent Subsidiary is separately subject to the periodic reporting requirements of the Exchange Act.

(b) Each of Parent’s consolidated financial statements contained or incorporated by reference in the Parent SEC Filings (as amended, supplemented or restated, if applicable), including the related notes and schedules, was prepared (except as indicated in the notes thereto) in accordance with GAAP applied on a consistent basis throughout the periods indicated, and each such consolidated financial statement presented fairly, in all material respects, the consolidated financial position, results of operations, stockholders’ equity and cash flows of Parent and its consolidated subsidiaries as of the respective dates thereof and for the respective periods indicated therein (subject, in the case of unaudited quarterly financial statements, to normal year-end adjustments).

(c) The records, systems, controls, data and information of Parent and the Parent Subsidiaries that are used in the system of internal accounting controls described in the following sentence are recorded, stored, maintained and operated under means that are under the exclusive ownership and direct control of Parent or the Parent Subsidiaries or accountants, except for any non-exclusive ownership and non-direct control that would not reasonably be expected to have a materially adverse effect on the system of internal accounting controls.

management’s authorization; (2) transactions are recorded as necessary to permit preparation of the financial statements of Parent and the Parent Subsidiaries and to maintain accountability for the assets of Parent and the Parent Subsidiaries; (3) access to such assets is permitted only in accordance with management’s authorization; (4) the reporting of such assets is compared with existing assets at regular intervals; and (5) accounts, notes and other receivables and inventory are recorded accurately, and proper and adequate procedures are implemented to effect the collection thereof on a current and timely basis.

Since the enactment of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act, none of Parent, Merger Sub or any other Parent Subsidiary has made any prohibited loans to any director or executive officer of Parent (as defined in Rule 3b-7 promulgated under the Exchange Act).

Section 6.2 Conduct of Business by Parent.

(a) Parent covenants and agrees that, during the Interim Period, except to the extent required by Law, as may be agreed in writing by the Company (which consent shall not be unreasonably withheld, delayed or conditioned), as may be expressly required or permitted pursuant to this Agreement, or as set forth in Section 6.2(a) of the Parent Disclosure Letter, Parent shall, and shall cause each of the Parent Subsidiaries to, (i) conduct its business in the ordinary course and in a manner consistent with past practice in all material respects, and (ii) use its reasonable best efforts to maintain its material assets and properties in their current condition (normal wear and tear and damage caused by casualty or by any reason outside of Parent’s or the Parent Subsidiaries’ control excepted), preserve intact in all material respects its current business organization, goodwill, ongoing businesses and relationships with third parties, keep available the services of its present officers and key employees, and maintain the status of Parent as a REIT.

(b) Without limiting the foregoing, Parent covenants and agrees that, during the Interim Period, except to the extent required by Law, as may be agreed in writing by the Company (which consent shall not be unreasonably withheld, delayed or conditioned), as may be expressly required or permitted pursuant to this Agreement, or as set forth in Section 6.2(b) of the Parent Disclosure Letter, Parent shall not, and shall not cause or permit any of the Parent Subsidiaries to, do any of the following:

(i) except for the Charter Amendment, amend or propose to amend the Parent Charter or Parent Bylaws (or such equivalent organizational or governing documents of any Parent Subsidiary material to Parent and the Parent Subsidiaries, considered as a whole, if such amendment would be adverse to Parent or the Company);

(ii) split, combine, reclassify or subdivide any shares of stock or other equity securities or ownership interests of Parent, Merger Sub or any other Parent Subsidiary;

6.2(b)(vi), provided that the aggregate net proceeds from the shares of Parent Common Stock issued pursuant to this Section 6.2(b)(iv)(B) shall be no greater than the aggregate amount paid (including expenses incurred) by Parent or any Parent Subsidiary in connection with the acquisitions made pursuant to Section 6.2(b)(vi), and (C) otherwise in the ordinary course and in a manner consistent with past practice;

(v) grant, confer or award, except in the ordinary course of business consistent with past practice and except as may be required under agreements executed prior to the date of this Agreement described on Section 6.2(b)(v) or under any existing Parent Benefit Plan, options, convertible securities, restricted stock units, restricted stock, performance shares, equity-based compensation or other rights to acquire, or denominated in, any of Parent’s or any of the Parent Subsidiaries’ capital stock or take any action not otherwise contemplated by this Agreement to cause to be exercisable any otherwise unexercisable option under any existing stock plan of Parent or any Parent Subsidiary (except as otherwise provided by the terms of any unexercisable options or other equity awards outstanding on the date of this Agreement or otherwise permitted to be granted under clause (A), (B) or (C) below), other than (A) grants to be made in accordance with Parent’s customary schedule or as otherwise approved by Parent’s Compensation Committee, (B) customary grants made to newly hired employees or with respect to promotions or Parent’s equity compensation review process, in each of the above case in the ordinary course of business consistent with past practice, or (C) in connection with this Merger or any other acquisition by Parent or any Parent Subsidiary with a Third Party permitted by this Agreement;

(vii) adopt a plan of merger, complete or partial liquidation or resolutions providing for or authorizing such merger, liquidation or a dissolution, consolidation, recapitalization or bankruptcy reorganization, except (A) by a Parent Subsidiary in connection with any acquisitions permitted pursuant to Section 6.2(b)(vi) in a manner that would not reasonably be expected to be adverse to Parent or to prevent or impair the ability of Parent to consummate the Merger or (B) for the merger, dissolution and liquidation of Parent Subsidiaries in the ordinary course of business consistent with past practice, which, individually or in the aggregate, would not reasonably be expected to be material to Parent;

(viii) fail to duly and timely file all material reports and other material documents required to be filed with all Governmental Authorities and other authorities (including the New York Stock Exchange), subject to extensions permitted by Law;

(ix) take any action that could, or fail to take any action, the failure of which could, reasonably be expected to cause (A) Parent to fail to qualify as a REIT or (B) any Parent Subsidiary to cease to be treated as any of (1) a partnership or disregarded entity for federal income tax purposes or (2) a qualified REIT subsidiary, a taxable REIT subsidiary or a REIT under the applicable provisions of Section 856 of the Code, as the case may be;

(x) take any action that could, or fail to take any action, the failure of which could, reasonably be expected to prevent the Merger from qualifying as a reorganization within the meaning of Section 368(a) of the Code;

(xi) take, or agree to commit to take, any action that would reasonably be expected to result in any of the conditions to the Merger set forth in Article VII not being satisfied; or

(xii) authorize, or enter into any contract, agreement, commitment or arrangement to do any of the foregoing.

(c) Notwithstanding anything to the contrary set forth in this Agreement, nothing in this Agreement shall prohibit Parent from taking any action, at any time or from time to time, that in the reasonable judgment of the Parent Board, upon advice of counsel to Parent, is reasonably necessary for Parent to continue to maintain its qualification as a REIT under the Code for any period or portion thereof ending on or prior to the Effective Time, including without limitation, making dividend or distribution payments to stockholders of Parent in accordance with this Agreement.

Each of the Company and Parent shall use its reasonable best efforts to have the Form S-4 declared effective under the Securities Act as promptly as practicable after such filing and keep the Form S-4 effective for so long as necessary to complete the Merger. Each of the Company and Parent shall furnish all information concerning itself, its Affiliates and the holders

of its capital stock to the other and provide such other assistance as may be reasonably requested in connection with the preparation, filing and distribution of the Form S-4 and Joint Proxy Statement. The Form S-4 and Joint Proxy Statement shall include all information reasonably requested by such other party to be included therein. Each of the Company and Parent shall promptly notify the other upon the receipt of any comments from the SEC or any request from the SEC for amendments or supplements to the Form S-4 or Joint Proxy Statement, and shall provide the other with copies of all correspondence between it and its Representatives, on one hand, and the SEC, on the other hand. Each of the Company and Parent shall use its reasonable best efforts to respond as promptly as practicable to any comments from the SEC with respect to the Joint Proxy Statement, and Parent shall use its reasonable best efforts to respond as promptly as practicable to any comment from the SEC with respect to the Form S-4. Notwithstanding the foregoing, prior to filing the Form S-4 (or any amendment or supplement thereto) or mailing the Joint Proxy Statement (or any amendment or supplement thereto) or responding to any comments of the SEC with respect thereto, each of the Company and Parent (i) shall provide the other an opportunity to review and comment on such document or response (including the proposed final version of such document or response) and (ii) shall include in such document or response all comments reasonably proposed by the other. Parent shall advise the Company, promptly after it receives notice thereof, of the time of effectiveness of the Form S-4, the issuance of any stop order relating thereto or the suspension of the qualification of the Parent Common Stock issuable in connection with the Merger for offering or sale in any jurisdiction, and Parent shall use its reasonable best efforts to have any such stop order or suspension lifted, reversed or otherwise terminated. Parent shall also take any other action (other than qualifying to do business in any jurisdiction in which it is not now so qualified) 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 Charter Amendment, and the Company shall furnish all information concerning the Company and the holders of its capital stock as may be reasonably requested in connection with any such actions.

(b) If, at any time prior to the Effective Time, any information relating to the Company or Parent, or any of their respective Affiliates, should be discovered by the Company or Parent which, in the reasonable judgment of the Company or Parent, should be set forth in an amendment of, or a supplement to, any of the Form S-4 or the Joint Proxy Statement, so that any of such documents would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party which discovers such information shall promptly notify the other parties hereto, and the Company and Parent shall cooperate in the prompt filing with the SEC of any necessary amendment of, or supplement to, the Joint Proxy Statement or the Form S-4 and, to the extent required by Law, in disseminating the information contained in such amendment or supplement to stockholders of the Company and the stockholders of Parent. Nothing in this Section 6.3(b) shall limit the obligations of any party under Section 6.3(a). For purposes of Section 4.8, Section 5.8 and this Section 6.3, any information concerning or related to the Company, its Affiliates or the Company Stockholder Meeting will be deemed to have been provided by the Company, and any information concerning or related to Parent, its Affiliates or the Parent Stockholder Meeting will be deemed to have been provided by Parent.

The Company shall, through the Company Board, recommend to its stockholders that they give the Company Stockholder Approval, include such recommendation in the Joint Proxy Statement and solicit and use its reasonable best efforts to obtain the Company Stockholder Approval, except to the extent that the Company Board shall have made an Adverse Recommendation Change as permitted by Section 6.5(c). Nothing contained in this Agreement shall be deemed to relieve the Company of its obligation to submit the Merger to its stockholders for a vote on the approval thereof. The Company agrees that, unless this Agreement shall have been terminated in accordance with Section 8.1, its obligations to hold the Company Stockholder Meeting pursuant to this Section 6.3(c) shall not be affected by the commencement, public proposal, public disclosure or communication to the Company of any Company Acquisition Proposal or by any Adverse Recommendation Change.

(e) The Company and Parent will use their respective reasonable best efforts to hold the Company Stockholder Meeting and the Parent Stockholder Meeting on the same date and as soon as practicable after the date of this Agreement.

Section 6.4 Access to Information; Confidentiality.

(a) During the Interim Period, to the extent permitted by applicable Law and contracts, and subject to the reasonable restrictions imposed from time to time upon advice of counsel, each of the Company and Parent shall, and shall cause each of the Parent Subsidiaries and the Company Subsidiaries, respectively, to, afford to the other party and to the Representatives of such other party reasonable access during normal business hours and upon reasonable advance notice to all of their respective properties, offices, books, contracts, commitments, personnel and records and, during such period, each of the Company and Parent shall, and shall cause each of the Company Subsidiaries and the Parent Subsidiaries, respectively, to, furnish reasonably promptly to the other party (i) a copy of each report, schedule, registration statement and other document filed by it during such period pursuant to the requirements of

federal or state securities Laws, and (ii) all other information (financial or otherwise) concerning its business, properties and personnel as such other party may reasonably request. Subject to the terms of the Company Leases, Parent, at its own expense, shall have the right to such reasonable access during normal business hours and upon reasonable advance notice in order to prepare or cause to be prepared surveys, inspections, engineering studies, environmental assessments and other tests, examination or studies with respect to the Company Property that Parent deems to be reasonably necessary, so long as such access does not unduly interfere with the Company’s ordinary conduct of business; provided, that Parent indemnify the Company for any losses, costs or damages caused by such access. Notwithstanding the foregoing, neither the Company nor Parent shall be required by this Section 6.4 to provide the other party or the Representatives of such other party with access to or to disclose information (x) that is subject to the terms of a confidentiality agreement with a third party entered into prior to the date of this Agreement or entered into after the date of this Agreement in the ordinary course of business consistent with past practice (provided, however, that the withholding party shall use its reasonable best efforts to obtain the required consent of such third party to such access or disclosure), (y) the disclosure of which would violate any Law or fiduciary duty (provided, however, that the withholding party shall use its reasonable best efforts to make appropriate substitute arrangements to permit reasonable disclosure not in violation of any Law or fiduciary duty) or (z) that is subject to any attorney-client privilege (provided, however, that the withholding party shall use its reasonable best efforts to allow for such access or disclosure to the maximum extent that does not result in a loss of attorney-client privilege). (b) Each of the Company and Parent will hold, and will cause its Representatives and Affiliates to hold, any nonpublic information, including any information exchanged pursuant to this Section 6.4, in confidence to the extent required by and in accordance with, and will otherwise comply with, the terms of the Confidentiality Agreements. (c) Each of the Company and Parent agree to give prompt written notice to the other upon becoming aware of the occurrence or impending occurrence of any event or circumstance relating to it or any of the Company Subsidiaries or the Parent Subsidiaries, respectively, which (i) could reasonably be expected to have, individually or in the aggregate, a Company Material Adverse Effect or a Parent Material Adverse Effect, as the case may be, or (ii) if unremedied by the Effective Time, would cause or constitute a material breach of any of its representations, warranties, or covenants contained herein, and to use its reasonable best efforts to prevent or promptly to remedy the same; provided, however, that no such notification shall affect the representations and warranties of any party or relieve any party of any breach of any such representation or warranty or affect the remedies available to the party receiving notice hereunder.

Section 6.5 Company Acquisition Proposals.

(a) Subject to the other provisions of this Section 6.5, during the Interim Period, the Company shall not, and shall cause each of the Company Subsidiaries, and its and their officers and directors, managers or equivalent not to, and shall use its reasonable best efforts to cause any other Representatives of the Company or the Company Subsidiaries not to, directly or indirectly through another Person, (i) solicit, initiate, knowingly encourage or knowingly facilitate any inquiry, discussion, offer or request that constitutes, or could reasonably be expected to lead to, a Company Acquisition Proposal (provided that for purposes of this Section 6.5(a), the references in the definition of Company Acquisition Proposal to “twenty percent (20%)” shall be deemed to be five percent (5%)) (an “Inquiry”), (ii) engage in any

discussions or negotiations regarding, or furnish to any Third Party any non-public information in connection with, or otherwise cooperate in any way with, or knowingly facilitate in any way any effort by, any Third Party in connection with, any Company Acquisition Proposal or Inquiry, (iii) approve or recommend a Company Acquisition Proposal, or enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement, share purchase agreement, asset purchase agreement, share exchange agreement, option agreement or other similar definitive agreement (other than an Acceptable Confidentiality Agreement entered into in accordance with this Section 6.5) providing for or relating to a Company Acquisition Proposal (an “Alternative Acquisition Agreement”), or (iv) propose or agree to do any of the foregoing.

(b) Notwithstanding anything to the contrary in this Section 6.5(b), at any time prior to obtaining the Company Stockholder Approval, the Company may, in response to an unsolicited bona fide written Company Acquisition Proposal by a Third Party made after the date of this Agreement (that did not result from a breach of this Section 6.5) (i) furnish non-public information to such Third Party (and such Third Party’s Representatives) making a Company Acquisition Proposal (provided, however, that (A) prior to so furnishing such information, the Company receives from the Third Party an executed Acceptable Confidentiality Agreement, and (B) any non-public information concerning the Company or the Company Subsidiaries that is provided to such Third Party shall, to the extent not previously provided to Parent or Merger Sub, be provided to Parent or Merger Sub prior to or simultaneously with providing it to such Third Party), and (ii) engage in discussions or negotiations with such Third Party (and such Third Party’s Representatives) with respect to the Company Acquisition Proposal if, in the case of each of clauses (i) and (ii): (x) the Company Board determines in good faith, after consultation with its financial and legal advisors, that such Company Acquisition Proposal constitutes, or could reasonably be expected to lead to, a Superior Proposal, and (y) the Company Board determines in good faith, after consultation with legal counsel, that failure to take such action would be reasonably likely to be inconsistent with the directors’ duties under applicable Law; provided, however, that in each of the foregoing clauses (i) and (ii), such Company Acquisition Proposal was not solicited in violation of Section 6.5.

(c) The Company shall notify Parent promptly (but in no event later than 24 hours) after receipt of any Company Acquisition Proposal or any request for nonpublic information relating to the Company or any Company Subsidiary by any Third Party, or any Inquiry from any Person seeking to have discussions or negotiations with the Company relating to a possible Company Acquisition Proposal. Such notice shall be made orally and confirmed in writing, and shall indicate the identity of the Third Party making the Company Acquisition Proposal or Inquiry and the material terms and conditions of any Inquiries, proposals or offers (including a copy thereof if in writing and any related documentation or correspondence). The Company shall also promptly, and in any event within 24 hours, notify Parent, orally and in writing, if it enters into discussions or negotiations concerning any Company Acquisition Proposal or provides nonpublic information or data to any person in accordance with this Section 6.5(c) and keep the other party informed of the status and terms of any such proposals, offers, discussions or negotiations on a current basis, including by providing a copy of all material documentation or correspondence relating thereto.

(d) Except as permitted by this Section 6.5(d), neither the Company Board nor any committee thereof shall (i) withhold, withdraw, qualify or modify (or publicly propose to withhold, withdraw, qualify or modify), in a manner adverse to Parent or Merger Sub, the Company Recommendation, (ii) approve, adopt or recommend (or publicly propose to approve, adopt or recommend) any Company Acquisition Proposal, (iii) fail to include the Company Recommendation in the Joint Proxy Statement or any Schedule 14D-9, as applicable, (iv) fail to publicly recommend against any Company Acquisition Proposal within ten (10) business days of the request of Parent and reaffirm the Company Recommendation within ten (10) business days (any of the actions described in clauses (i), (ii), (iii) and (iv) of this Section 6.5(d), an “Adverse Recommendation Change”), or (v) approve, adopt, declare advisable or recommend (or agree to, resolve or propose to approve, adopt, declare advisable or recommend), or cause or permit the Company to enter into, any Alternative Acquisition Agreement (other than an Acceptable Confidentiality Agreement entered into in accordance with this Section 6.5). Notwithstanding anything to the contrary set forth in this Agreement, at any time prior to obtaining the Company Stockholder Approval, the Company Board shall be permitted to effect an Adverse Recommendation Change if the Company Board (x) has received a Company Acquisition Proposal that, in the good faith determination of the Company Board, after consultation with its financial and legal advisors, constitutes a Superior Proposal, after having complied with, and giving effect to all of the adjustments which may be offered by Parent and Merger Sub pursuant to Section 6.5(e), and (y) determines in good faith, after consultation with its financial and legal advisors, that failure to take such action would be inconsistent with the directors’ duties under applicable Law.

(e) The Company Board shall not be entitled to effect an Adverse Recommendation Change as permitted under Section 6.5(d) unless (i) the Company has provided a written notice (a “Notice of Superior Proposal”) to Parent and Merger Sub that the Company intends to take such action and describing the material terms and conditions of, and attaching a complete copy of, the Superior Proposal that is the basis of such action (it being understood that such material terms shall include the identity of the Third Party), (ii) during the three (3) Business Day period following Parent’s and Merger Sub’s receipt of the Notice of Superior Proposal, the Company shall, and shall cause its Representatives to, negotiate with Parent and Merger Sub in good faith (to the extent Parent and Merger Sub desire to negotiate) to make such adjustments in the terms and conditions of this Agreement so that such Superior Proposal ceases to constitute a Superior Proposal, and (iii) following the end of the three (3) Business Day period, the Company Board shall have determined in good faith, after consultation with its financial and legal advisors, taking into account any changes to this Agreement proposed in writing by Parent and Merger Sub in response to the Notice of Superior Proposal or otherwise, that the Superior Proposal giving rise to the Notice of Superior Proposal continues to constitute a Superior Proposal. Any amendment to the financial terms or any other material amendment of such Superior Proposal shall require a new Notice of Superior Proposal, and the Company shall be required to comply again with the requirements of this Section 6.5(e); provided, however, that references to the three (3) Business Day period above shall then be deemed to be references to a two (2) Business Day period.

(f) Nothing contained in this Section 6.5 or elsewhere in this Agreement shall prohibit the Company or the Company Board, directly or indirectly through its Representatives, from disclosing to the Company’s stockholders a position contemplated by

Rule 14e-2(a) and Rule 14d-9 promulgated under the Exchange Act; provided, however, that any disclosure other than a “stop, look and listen” or similar communication of the type contemplated by Rule 14d-9(f) promulgated under the Exchange Act, an express rejection of any applicable Company Acquisition Proposal or an express reaffirmation of the Company Recommendation to the Company’s stockholders in favor of the Merger shall be deemed to be an Adverse Recommendation Change.

(g) The Company shall, and shall cause each of the Company Subsidiaries (other than any Company Subsidiary in which the Company directly or indirectly owns 25% or less of the outstanding equity interests) and its and their officers and directors, managers or equivalent, and shall use its reasonable best efforts to cause any other Representatives of the Company or the Company Subsidiaries to (i) immediately cease any existing discussions, negotiations or communications with any Person conducted heretofore with respect to any Company Acquisition Proposal and (ii) take such action as is necessary to enforce any confidentiality or “standstill” provisions or provisions of similar effect to which the Company or any of the Company Subsidiaries is a party or of which the Company or any of the Company Subsidiaries is a beneficiary. The Company shall use all reasonable efforts to cause all Third Parties who have been furnished confidential information regarding the Company in connection with the solicitation of or discussions regarding a Company Acquisition Proposal within the six (6) months prior to the date of this Agreement to promptly return or destroy such information (to the extent that the Company is entitled to have such information returned or destroyed).

(h) For purposes of this Agreement:

(i) “Company Acquisition Proposal” shall mean any proposal or offer for (or expression by a Third Party that it is considering or may engage in), whether in one transaction or a series of related transactions, (i) any merger, consolidation, share exchange, business combination or similar transaction involving the Company or any of the Company Subsidiaries, (ii) any sale, lease, exchange, mortgage, pledge, license, transfer or other disposition, directly or indirectly, by merger, consolidation, sale of equity interests, share exchange, joint venture, business combination or otherwise, of any assets of the Company or any Company Subsidiary representing twenty percent (20%) or more of the consolidated assets of the Company and the Company Subsidiaries, taken as a whole as determined on a book-value basis, (iii) any issue, sale or other disposition of (including by way of merger, consolidation, joint venture, business combination, share exchange or any similar transaction) securities (or options, rights or warrants to purchase, or securities convertible into, such securities) representing twenty percent (20%) or more of the voting power of the Company, (iv) any tender offer or exchange offer in which any Person or “group” (as such term is defined in Rule 13d-3 promulgated under the Exchange Act) shall seek to acquire beneficial ownership (as such term is defined in Rule 13d-3 promulgated under the Exchange Act), or the right to acquire beneficial ownership, of twenty percent (20%) or more of the outstanding shares of any class of voting securities

of the Company, (v) any recapitalization, restructuring, liquidation, dissolution or other similar type of transaction with respect to the Company in which a Third Party shall acquire beneficial ownership of twenty percent (20%) or more of the outstanding shares of any class of voting securities of the Company or (vi) any transaction which is similar in form, substance or purpose to any of the foregoing transactions; provided, however, that the term “Company Acquisition Proposal” shall not include (x) the Merger or the other transactions contemplated by this Agreement or (y) any proposal or offer relating to any existing purchase option, right of first offer, right of first refusal or buy/sell provision contained in any agreement to which the Company or any Company Subsidiary is a party.

(ii) “Superior Proposal” shall mean a bona fide written Company Acquisition Proposal (except that, for purposes of this definition, the references in the definition of “Company Acquisition Proposal” to “twenty percent (20%)” shall be replaced by “fifty percent (50%)”) made by a Third Party on terms that the Company Board determines in good faith, after consultation with the Company’s financial and legal advisors, taking into account all financial, legal, regulatory and any other aspects of the transaction described in such proposal, including the identity of the Person making such proposal, as well as any changes to the financial terms of this Agreement proposed by Parent and Merger Sub in response to such proposal or otherwise, to be more favorable to the Company and the Company’s stockholders (solely in their capacity as such) from a financial point of view than the transactions contemplated by this Agreement.

Section 6.6 Appropriate Action; Consents; Filings.

(a) Upon the terms and subject to the conditions set forth in this Agreement (including Section 6.5), each of the Company and Parent shall (and shall cause the Company Subsidiaries and the Parent Subsidiaries, respectively, to) use its 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 under applicable Law or pursuant to any contract or agreement to consummate and make effective, as promptly as practicable, the Merger and the other transactions contemplated by this Agreement, including (i) the taking of all actions necessary to cause the conditions to Closing set forth in Article VII to be satisfied, (ii) the obtaining of all necessary actions or nonactions, waivers, consents and approvals from Governmental Authorities or other Persons necessary in connection with the consummation of the Merger and the other transactions contemplated by this Agreement and the making of all necessary registrations and filings (including filings with Governmental Authorities, if any) and the taking of all reasonable steps as may be necessary to obtain an approval or waiver from, or to avoid an action or proceeding by, any Governmental Authority or other Persons necessary in connection with the consummation of the Merger and the other transactions contemplated by this Agreement, (iii) the defending of any lawsuits or other legal proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the Merger or the other transactions contemplated by this Agreement,

including seeking to have any stay or temporary restraining order entered by any court or other Governmental Authority vacated or reversed, the avoidance of each and every impediment under any antitrust, merger control, competition or trade regulation Law that may be asserted by any Governmental Authority with respect to the Merger so as to enable the Closing to occur as soon as reasonably possible, and (iv) the execution and delivery of any additional instruments necessary to consummate the Merger and the other transactions contemplated by this Agreement and to fully carry out the purposes of this Agreement.

(b) In connection with and without limiting the foregoing, each of Parent and the Company shall give (or shall cause the Parent Subsidiaries or the Company Subsidiaries, respectively, to give) any notices to Third Parties, and Parent shall use, and cause each of its Affiliates to use, its reasonable best efforts, and the Company shall use its reasonable best efforts to cooperate with Parent in its efforts, to obtain any Third Party consents not covered by Section 6.6(a) that are necessary, proper or advisable to consummate the Merger; provided, however, that Parent shall promptly reimburse the Company for any expenses and costs incurred in connection with the Company’s or its Affiliates’ obligations under this Section 6.6(b). Each of the parties hereto will furnish to the other such necessary information and reasonable assistance as the other may request in connection with the preparation of any required governmental filings or submissions and will cooperate in responding to any inquiry from a Governmental Authority, including immediately informing the other party of such inquiry, consulting in advance before making any presentations or submissions to a Governmental Authority, and supplying each other with copies of all material correspondence, filings or communications between either party and any Governmental Authority with respect to this Agreement. To the extent practicable, and permitted by a Governmental Authority, each party hereto shall permit representatives of the other party to participate in meetings (whether by telephone or in person) with such Governmental Authority. Notwithstanding the foregoing, obtaining any approval or consent from any third party pursuant to this Section 6.6(b) shall not be considered a condition to the obligations of Parent and Merger Sub to consummate the Merger.

(c) Notwithstanding anything to the contrary in this Agreement, in connection with obtaining any approval or consent from any Person (other than any Governmental Authority) with respect to the Merger, without the prior written consent of Parent, none of the Company, any of the Company Subsidiaries or any of the Company’s or Company Subsidiary’s Representatives, shall pay or commit to pay to such Person whose approval or consent is being solicited any cash or other consideration, make any accommodation or commitment or incur any liability or other obligation to such Person. The Company shall cooperate with Parent and the Purchaser with respect to accommodations that may be requested or appropriate to obtain such consents.

(b) The Company shall give prompt notice to Parent, and Parent shall give prompt notice to the Company, if (i) any representation or warranty made by it contained in this Agreement becomes untrue or inaccurate such that the applicable closing conditions would reasonably expected to be incapable of being satisfied by the Outside Date or (ii) it fails to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement; provided, however, that no such notification shall affect the representations, warranties, covenants or agreements of the parties or the conditions to the obligations of the parties under this Agreement.

(c) The Company shall give prompt notice to Parent, and Parent shall give prompt notice to the Company, of any actions, suits, claims, investigations or proceedings commenced or, to such party’s knowledge, threatened against, relating to or involving such party or any of the Company Subsidiaries or the Parent Subsidiaries, respectively, which relate to this Agreement, the Merger or the other transactions contemplated by this Agreement. The Company shall give Parent the opportunity to reasonably participate in the defense and settlement of any stockholder litigation against the Company and/or its directors relating to this Agreement and the transactions contemplated hereby, and no such settlement shall be agreed to without Parent’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed), unless such settlement involves only the payment of money and the amount of such settlement shall be fully covered by insurance proceeds. Parent shall give the Company the opportunity to reasonably participate in the defense and settlement of any stockholder litigation against Parent and/or its directors relating to this Agreement and the transactions contemplated hereby, and no such settlement shall be agreed to without the Company’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed), unless such settlement involves only the payment of money and the amount of such settlement shall be fully covered by insurance proceeds.

Section 6.8 Public Announcements. The Company, Parent and Merger Sub shall, to the extent reasonably practicable, consult with each other before issuing any press release or otherwise making any public statements or filings with respect to this Agreement or any of the transactions contemplated hereby, and none of the parties shall issue any such press release or make any such public filing prior to obtaining the other parties’ consent (which consent shall not be unreasonably withheld, conditioned or delayed); provided, however, that a party may, without obtaining the other parties’ consent, issue such press release or make such public statement or filing as may be required by Law, Order or the applicable rules of any stock exchange or the applicable provisions of any listing agreement of any party hereto. If for any reason it is not practicable to consult with the other party before making any public statement with respect to this Agreement or any of the transactions contemplated hereby, then the party making such statement shall not make a statement that is inconsistent with public statements or filings to which the other party had previously consented.

Section 6.9 Directors’ and Officers’ Indemnification and Insurance.

(a) Parent and Merger Sub agree that all rights to exculpation and indemnification for acts or omissions occurring at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time (including any matters arising in connection with the transactions contemplated by this Agreement), now existing in favor of the current or former directors, officers, partners, members, trustees or employees, as the case may be, of the Company or the Company Subsidiaries as provided in the Company Charter or the Company Bylaws or each of the Company Subsidiaries’ respective articles or certificates of incorporation or bylaws (or comparable organizational or governing documents) or in any agreement shall survive the Merger and shall continue in full force and effect in accordance with their terms. Parent and the Surviving Entity shall (and Parent shall cause the Surviving Entity to) (i) indemnify, defend and hold harmless, and advance expenses to, Indemnitees with respect to all acts or omissions by them in their capacities as such at any time prior to the Effective Time, to the fullest extent required by: (x) the Company Charter or Company Bylaws, or the articles or certificates of incorporation or bylaws (or comparable organizational or governing documents) of any of the Company Subsidiaries, in each case, as in effect on the date of this Agreement, (y) any indemnification agreement of the Company or the Company Subsidiaries or other applicable contract as in effect on the date of this Agreement and listed in the Company Disclosure Letter, or (z) applicable Law, and (ii) not amend, repeal or otherwise modify any such provisions referenced in subsections (i)(x) and (y) above in any manner that would adversely affect the rights thereunder of any Indemnitees.

(b) Without limiting the provisions of Section 6.9(a), during the period commencing as of the Effective Time and ending on the sixth (6th) anniversary of the Effective Time, Parent and the Surviving Entity shall (and Parent shall cause the Surviving Entity to): (i) indemnify and hold harmless each Indemnitee against and from any costs or expenses (including attorneys’ fees), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, to the extent such claim, action, suit, proceeding or investigation arises out of or pertains to (x) any action or omission or alleged action or omission in such Indemnitee’s capacity as a director, officer, partner, member, trustee or employee of the Company or any of the Company Subsidiaries, or (y) this Agreement and any of the transactions contemplated hereby, including the Merger; and (ii) pay in advance of the final disposition of any such claim, action, suit, proceeding or investigation the expenses (including attorneys’ fees) of any Indemnitee upon receipt of an undertaking by or on behalf of such Indemnitee to repay such amount if it shall ultimately be determined that such Indemnitee is not entitled to be indemnified. Notwithstanding anything to the contrary contained in this Section 6.9(b) or elsewhere in this Agreement, neither Parent nor the Surviving Entity shall (and Parent shall cause the Surviving Entity not to) settle or compromise or consent to the entry of any judgment or otherwise seek termination with respect to any claim, action, suit, proceeding or investigation for which indemnification may be sought under this Section 6.9(b) unless such settlement, compromise, consent or termination includes an unconditional release of all Indemnitees from all liability arising out of such claim, action, suit, proceeding or investigation, and does not include an admission of fault or wrongdoing by any Indemnitee. Notwithstanding anything to the

contrary set forth in this Agreement, Parent or the Surviving Entity (i) shall not be liable for any settlement effected without their prior written consent and (ii) shall not have any obligation hereunder to any Indemnitee to the extent that a court of competent jurisdiction shall determine in a final and non-appealable order that such indemnification is prohibited by applicable Law, in which case the Indemnitee shall promptly refund to Parent or the Surviving Entity the amount of all such expenses theretofore advanced pursuant hereto.

(c) Prior to the Effective Time, the Company shall or, if the Company is unable to, Parent shall cause the Surviving Entity as of the Effective Time to, obtain and fully pay the premium for the non-cancellable extension of the directors’ and officers’ liability coverage of the Company’s existing directors’ and officers’ insurance policies and the Company’s existing fiduciary liability insurance policies (collectively, the “D&O Insurance”), in each case, for a claims reporting or discovery period of at least six (6) years from and after the Effective Time with respect to any claim related to any period or time at or prior to the Effective Time from an insurance carrier with the same or better credit rating as the Company’s current insurance carrier with respect to D&O Insurance with terms, conditions, retentions and limits of liability that are no less favorable than the coverage provided under the Company’s existing policies and with policy limits no less than the limits on the Company’s existing policies as long as the annual premium does not exceed 110% of the annual premium under the Company’s existing policies. If the Company or the Surviving Entity for any reason fails to obtain such “tail” insurance policies as of the Effective Time, (i) the Surviving Entity shall continue to maintain in effect, for a period of at least six (6) years from and after the Effective Time, the D&O Insurance in place as of the date hereof with the Company’s current insurance carrier or with an insurance carrier with the same or better credit rating as the Company’s current insurance carrier with respect to D&O Insurance with terms, conditions, retentions and limits of liability that are no less favorable than the coverage provided under the Company’s existing policies as of the date hereof, or (ii) Parent shall provide, or shall cause the Surviving Entity to provide, for a period of not less than six (6) years after the Effective Time, the Indemnitees who are insured under the Company’s D&O Insurance with comparable D&O Insurance that provides coverage for events occurring at or prior to the Effective Time from an insurance carrier with the same or better credit rating as the Company’s current insurance carrier, that is no less favorable than the existing policy of the Company (which may be provided under Parent’s D&O Insurance policy) or, if substantially equivalent insurance coverage is unavailable, the best available coverage; provided, however, that Parent and the Surviving Entity shall not be required to pay an annual premium for the D&O Insurance in excess of 300% of the annual premium currently paid by the Company for such insurance; and provided, further, that if the annual premiums of such insurance coverage exceed such amount, Parent or the Surviving Entity shall be obligated to obtain a policy with the greatest coverage available, with respect to matters occurring prior to the Effective Time, for a cost not exceeding such amount.

(d) The Indemnitees to whom this Section 6.9 applies shall be third party beneficiaries of this Section 6.9. The provisions of this Section 6.9 are intended to be for the benefit of each Indemnitee and his or her successors, heirs, executors, trustees, fiduciaries, administrators or representatives. Parent shall pay all reasonable expenses, including attorney’s

fees, that may be incurred by any Indemnitee in successfully enforcing the indemnity and other obligations provided in this Section 6.9.

(e) The rights of each Indemnitee under this Section 6.9 shall be in addition to any rights such person or any employee of the Company or any Company Subsidiary may have under the Company Charter, the Company Bylaws or the certificate of incorporation or bylaws (or equivalent organizational or governing documents) of any of the Company Subsidiaries, or the Surviving Entity or any of its subsidiaries, or under any applicable Law or under any agreement of any Indemnitee or any employee with the Company or any of the Company Subsidiaries listed in Section 4.12(a)(iv) the Company Disclosure Letter.

(f) Notwithstanding anything contained in Section 9.1 or Section 9.7 to the contrary, this Section 6.9 shall survive the consummation of the Merger indefinitely and shall be binding, jointly and severally, on all successors and assigns of Parent, the Surviving Entity and its subsidiaries, and shall be enforceable by the Indemnitees and their successors, heirs or representatives. In the event that Parent or the Surviving Entity or any of its successors or assigns 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 transfers or conveys all or a majority 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 Entity, as applicable, shall succeed to the obligations set forth in this Section 6.9. The parties acknowledge and agree that Parent guarantees the payment and performance of the Surviving Entity’s obligations pursuant to this Section 6.9.

Section 6.10 Employee Benefit Matters.

(a) During the one (1)-year period commencing at the Effective Time, Parent shall, or shall cause the Surviving Entity to, provide to employees and former employees of the Company and any of the Company Subsidiaries (“Company Employees”) (i) a base salary or wage rate at least equal to the Company Employees’ base salary or wage rate in effect as of immediately prior to the Effective Time and (ii) employee benefits (other than any incentive compensation, equity-based compensation, defined benefit pension benefits and retiree medical benefits) that are, in the aggregate, no less favorable than the employee benefits (other than any incentive compensation, equity-based compensation, defined benefit pension benefits and retiree medical benefits) provided to similarly situated employees of Parent and its Subsidiaries under the Parent Benefit Plans.

(b) Parent shall provide, or shall cause the Surviving Entity to provide, to each Company Employee who is a participant in a Company Severance Pay Plan immediately prior to the Effective Time and whose employment with the Surviving Entity, Company Subsidiaries and its Affiliates is involuntarily terminated in a severance-qualifying manner during the one (1)-year period following the Effective Time, severance benefits that are no less favorable, in the aggregate, than the severance benefits, if any, that would have been provided to

such Company Employee pursuant to the terms of a Company Severance Pay Plan upon such an involuntary severance-qualifying termination of employment immediately prior to the Effective Time; provided that no such severance benefits shall be provided to any Company Employee who is a party to a Company Employment Agreement that otherwise provides for severance benefits.

(c) For purposes of eligibility and vesting, benefit accrual and determination of level of benefits under the compensation and benefit plans, programs agreements and arrangements of Parent, the Company, the Parent Subsidiaries, the Company Subsidiaries, the Surviving Entity and any of its subsidiaries or any respective Affiliate thereof providing benefits to any Company Employees after the Closing, and in which such Company Employees did not participate prior to the Effective Time (the “New Plans”), including for purposes of accrual of vacation and other paid time off and severance benefits under New Plans (but excluding any New Plan that is established after the Closing that does not recognize service prior to its adoption), each Company Employee shall be credited with his or her years of service with the Company, the Company Subsidiaries and their respective Affiliates (and any additional service with any predecessor employer) before the Closing, to the same extent as such Company Employee was entitled, before the Closing, to credit for such service under any similar Company Benefit Plan, except where such credit would result in a duplication of benefits. In addition, and without limiting the generality of the foregoing: (i) each Company Employee shall be immediately eligible to participate, without any waiting time, in any and all New Plans to the extent coverage under such New Plan replaces coverage under a comparable Company Benefit Plan in which such Company Employee participated immediately before such replacement; and (ii) for purposes of each New Plan providing medical, dental, pharmaceutical and/or vision benefits to any Company Employee, Parent shall cause all pre-existing condition exclusions and actively-at-work requirements of such New Plan to be waived for such employee and his or her covered dependents except to the extent such pre-existing conditions and actively-at-work requirements would apply under the analogous Company Benefit Plan, and Parent shall use reasonable efforts to cause any eligible expenses incurred by such Company employee and his or her covered dependents under a Company Benefit Plan during the portion of the plan year prior to the Effective Time to be taken into account under such New Plan for purposes of satisfying all deductible, co-insurance, co-payment and maximum out-of-pocket requirements applicable to such employee and his or her covered dependents for the applicable plan year as if such amounts had been paid in accordance with such New Plan.

(d) For the avoidance of doubt and notwithstanding anything to the contrary herein or in any Company Benefit Plan, for purposes of any Company Benefit Plan listed in Section 6.10 of the Company Disclosure Letter, the Closing shall be deemed to constitute a “change in control” or “change of control.”

(e) Nothing contained herein shall be construed as requiring, and the Company shall take no action that would have the effect of requiring, Parent or the Surviving Entity to continue any specific employee benefit plans or to continue the employment of any specific person. The provisions of this Section 6.10 are solely for the benefit of the parties to this

Agreement, and no current or former director, officer, employee or independent contractor or any other person shall be a third-party beneficiary of this Section 6.10, and nothing herein shall be construed as an amendment to any Plan or other compensation or benefit plan or arrangement for any purpose.

Each of Parent and the Company shall use their reasonable best efforts to cause the Merger to qualify as a reorganization within the meaning of Section 368(a) of the Code, including by executing and delivering the officers’ certificates referred to therein.

The per share dividend amount payable by the Company shall be an amount equal to (i) the Company’s most recent quarterly dividend, multiplied by the number of days elapsed since the last dividend record date through and including the day prior to the day on which the Effective Time occurs, and divided by the actual number of days in the calendar quarter in which such dividend is declared, plus (ii) if necessary to enable the Company to make aggregate dividend distributions during its final taxable period equal to the Minimum Distribution Dividend, an additional amount (the “Additional Dividend Amount”) necessary so that the aggregate dividend payable is equal to the Minimum Distribution Dividend. The per share dividend amount payable by Parent shall be an amount equal to (i) Parent’s most recent quarterly dividend, multiplied by the number of days elapsed since the last dividend record date through and including the day prior to the day on which the Effective Time occurs, and divided by the actual number of days in the calendar quarter in which such dividend is declared, plus (ii) the Additional Dividend Amount, if any, divided by the Exchange Ratio. If the Company determines it is necessary to declare the Additional Dividend Amount, the Company shall notify Parent of such determination at least ten days prior to the Company Stockholder Meeting.

(b) In the event that a distribution with respect to the shares of Company Common Stock permitted under the terms of this Agreement (including pursuant to Section 6.1(b)(iii) and Section 6.12(a) above) has (i) a record date prior to the Effective Time and (ii) has not been paid as of the Effective Time, the holders of shares of Company Common Stock shall be entitled to receive such distribution from the Company at the time such shares are exchanged pursuant to Article III of this Agreement.

Section 6.13 Merger Sub. Parent shall take all actions necessary to (a) cause Merger Sub to perform its obligations under this Agreement and to consummate the Merger on the terms and conditions set forth in this Agreement, and (b) ensure that, prior to the Effective Time, Merger Sub shall not conduct any business or make any investments other than as specifically contemplated by this Agreement, or incur or guarantee any indebtedness.

Assuming that the Company delivers to Parent, in a timely fashion prior to the Effective Time, all requisite information necessary for Parent and Merger Sub to take the actions contemplated by this Section 6.14, the Company, Parent and Merger Sub each shall take all such steps as may be necessary or appropriate to ensure that (a) any dispositions of Company Common Stock (including derivative securities related to such stock) resulting from the Merger and the other transactions contemplated by this Agreement by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Company immediately prior to the Effective Time are exempt under Rule 16b-3 promulgated under the Exchange Act, and (b) any acquisitions of Parent Common Stock (including derivative securities related to such stock) resulting from the Merger and the other transactions contemplated by this Agreement by each individual who may become subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to Parent are exempt under Rule 16b-3 promulgated under the Exchange Act.

Section 6.15 Stock Exchange Listing. Parent shall use its reasonable best efforts to cause the shares of Parent Common Stock to be issued in the Merger to be approved for listing on the NYSE, subject to official notice of issuance, prior to the Effective Time.

(i) by either the Company or Parent pursuant to Section 8.1(b)(i) or Section 8.1(b)(iii) or by Parent pursuant to Section 8.1(d)(i) and (A) in the case of a termination pursuant to Section 8.1(b)(i), the Parent Stockholder Approval shall have been obtained and the Company Stockholder Approval shall not have been obtained prior to such termination, and (B) the Company (x) receives or has received a Company Acquisition Proposal after the date of this Agreement, which proposal has been publicly announced and (y) within twelve (12) months of the termination of this Agreement, consummates a transaction regarding, or executes a definitive agreement which is later consummated with respect to, a Company Acquisition Proposal, then the Company shall pay, or cause to be paid, to Parent a fee equal to $175,000,000 (the “Termination Fee”) plus, if not previously paid pursuant to the proviso below, the Expense Amount, by wire transfer of same day funds to an account designated by Parent, not later than the consummation of such transaction arising from such Company Acquisition Proposal; provided, however, that for purposes of this Section 8.3(a)(i), the references to “twenty percent (20%)” in the definition of Company Acquisition Proposal shall be deemed to be references to “fifty percent (50%)”; and provided, further, that in the event that the Agreement is terminated by either the Company or Parent pursuant to Section 8.1(b)(iii), the Company shall pay, or cause to be paid, to Parent the Expense Amount (by wire transfer to an account designated by Parent) within two (2) Business Days of such termination rather than when the Termination Fee becomes payable to Parent (if ever); or

(ii) by either the Company or Parent pursuant to Section 8.1(b)(i) or Section 8.1(b)(iv) or by the Company pursuant to Section 8.1(c) and (A) in the case of a termination pursuant to Section 8.1(b)(i), the Company Stockholder Approval shall have been obtained and the Parent Stockholder Approval shall not have been obtained prior to such termination, and (B) Parent (x)

receives or has received a bona fide Parent Acquisition Proposal, which proposal has been publicly announced and (y) within twelve (12) months of the termination of this Agreement, consummates a transaction regarding, or executes a definitive agreement which is later consummated with respect to, a Parent Acquisition Proposal, then Parent shall pay, or cause to be paid, to the Company the Termination Fee plus, if not previously paid pursuant to the proviso below, the Expense Amount, by wire transfer of same day funds to an account designated by the Company, not later than the consummation of such transaction arising from such Parent Acquisition Proposal; provided, however, that in the event that the Agreement is terminated by either the Company or Parent pursuant to Section 8.1(b)(iv), Parent shall pay, or cause to be paid, to the Company the Expense Amount (by wire transfer to an account designated by the Company) within two (2) Business Days of such termination rather than when the Termination Fee becomes payable to the Company (if ever); or

(iii) by Parent pursuant to Section 8.1(d)(ii), then the Company shall pay, or cause to be paid, to Parent the Termination Fee together with the Expense Amount, by wire transfer of same day funds to an account designated by Parent, within two (2) Business Days of such termination.

(b) Notwithstanding anything to the contrary set forth in this Agreement, the parties agree that:

(i) under no circumstances shall the Company or Parent be required to pay the Termination Fee earlier than one (1) full Business Day after receipt of appropriate wire transfer instructions from the party entitled to payment; and

(ii) under no circumstances shall the Company or Parent be required to pay the Termination Fee on more than one occasion.

(c) Each of the parties hereto acknowledges that (i) the agreements contained in this Section 8.3 are an integral part of the transactions contemplated by this Agreement, (ii) the Termination Fee is not a penalty, but is liquidated damages, in a reasonable amount that will compensate the Company or Parent, as the case may be, in the circumstances in which such fee is payable for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the transactions contemplated hereby, which amount would otherwise be impossible to calculate with precision, and (iii) without these agreements, the parties would not enter into this Agreement; accordingly, if the Company or Parent, as the case may be, fails to timely pay any amount due pursuant to this Section 8.3 and, in order to obtain such payment, either the Company or Parent, as the case may be, commences a suit that results in a judgment against the other party for the payment of any amount set forth in this Section 8.3, such paying

party shall pay the other party its costs and Expenses in connection with such suit, together with interest on such amount at the annual rate of ten percent (10%) for the period from the date such payment was required to be made through the date such payment was actually received, or such lesser rate as is the maximum permitted by applicable Law.

(d) (i) If one party to this Agreement (the “Termination Fee Payor”) is required to pay another party to this Agreement (the “Termination Fee Payee”) a Termination Payment, such Termination Payment shall be paid into escrow on the date such payment is required to be paid by the Termination Fee Payor pursuant to this Agreement by wire transfer of immediately available funds to an escrow account designated in accordance with this Section 8.3(d). In the event that the Termination Fee Payor is obligated to pay the Termination Fee Payee the Termination Payment, the amount payable to the Termination Fee Payee in any tax year of the Termination Fee Payee shall not exceed the lesser of (i) the Termination Payment of the Termination Fee Payee, and (ii) the sum of (A) the maximum amount that can be paid to the Termination Fee Payee without causing the Termination Fee Payee to fail to meet the requirements of Section 856(c)(2) and (3) of the Code for the relevant tax year, determined as if the payment of such amount did not constitute income described in Sections 856(c)(2) or 856(c)(3) of the Code (“Qualifying Income”), as determined by the Termination Fee Payee’s independent accountants, plus (B) in the event the Termination Fee Payee receives either (x) a letter from the Termination Fee Payee’s counsel indicating that the Termination Fee Payee has received a ruling from the IRS as described below in this Section 8.3(d) or (y) an opinion from the Termination Fee Payee’s outside counsel as described below in this Section 8.3(d), an amount equal to the excess of the Termination Payment less the amount payable under clause (A) above.

(ii) To secure the Termination Fee Payor’s obligation to pay these amounts, the Termination Fee Payor shall deposit into escrow an amount in cash equal to the Termination Payment with an escrow agent selected by the Termination Fee Payor on such terms (subject to this Section 8.3(d)) as shall be mutually agreed upon by the Termination Fee Payor, the Termination Fee Payee and the escrow agent. The payment or deposit into escrow of the Termination Payment pursuant to this Section 8.3(d) shall be made at the time the Termination Fee Payor is obligated to pay the Termination Fee Payee such amount pursuant to Section 8.3 by wire transfer. The escrow agreement shall provide that the Termination Payment in escrow or any portion thereof shall not be released to the Termination Fee Payee unless the escrow agent receives any one or combination of the following: (i) a letter from the Termination Fee Payee’s independent accountants indicating the maximum amount that can be paid by the escrow agent to the Termination Fee Payee without causing the Termination Fee Payee to fail to meet the requirements of Sections 856(c)(2) and (3) of the Code determined as if the payment of such amount did not constitute Qualifying Income, in which case the escrow agent shall release such amount to the Termination Fee Payee, or (ii) a letter from the Termination Fee Payee’s counsel indicating that (A) the Termination Fee Payee received a ruling from the IRS holding that the receipt by the Termination Fee Payee of the Termination Payment

would either constitute Qualifying Income or would be excluded from gross income within the meaning of Sections 856(c)(2) and (3) of the Code or (B) the Termination Fee Payee’s outside counsel has rendered a legal opinion to the effect that the receipt by the Termination Fee Payee of the Termination Payment would either constitute Qualifying Income or would be excluded from gross income within the meaning of Sections 856(c)(2) and (3) of the Code, in which case the escrow agent shall release the remainder of the Termination Payment to the Termination Fee Payee. The Termination Fee Payor agrees to amend this Section 8.3(d) at the reasonable request of the Termination Fee Payee in order to (i) maximize the portion of the Termination Payment that may be distributed to the Termination Fee Payee hereunder without causing the Termination Fee Payee to fail to meet the requirements of Sections 856(c)(2) and (3) of the Code, (ii) improve the Termination Fee Payee’s chances of securing a favorable ruling described in this Section 8.3(d) or (iii) assist the Termination Fee Payee in obtaining a favorable legal opinion from its outside counsel as described in this Section 8.3(d). Any amount of the Termination Payment that remains unpaid as of the end of a taxable year shall be paid as soon as possible during the following taxable year, subject to the foregoing limitations of this Section 8.3(d), provided that the obligation of the Termination Fee Payor to pay the unpaid portion of the Termination Payment shall terminate on the December 31 following the date which is four years from the date of this Agreement.

(e) For purposes of this Agreement: “Parent Acquisition Proposal” shall have the same meaning as “Company Acquisition Proposal with the word “Parent” replacing the words “the Company and/or any of the Company Subsidiaries” mutatis mutandis; provided, however, that for purposes of the definition of Parent Acquisition Proposal, (i) the reference to “twenty percent (20%)” in the definition of Company Acquisition Proposal shall be deemed to be reference to “fifty percent (50%)” and (ii) transactions in which Parent is the acquiring party shall not be included.

Section 8.4 Amendment. Subject to compliance with applicable Law, this Agreement may be amended by mutual agreement of the parties hereto by action taken or authorized by their respective boards of directors (or similar governing body or entity) at any time before or after receipt of the Company Stockholder Approval or the Parent Stockholder Approval and prior to the Effective Time; provided, however, that after the Company Stockholder Approval or the Parent Stockholder Approval has been obtained, there shall not be (a) any amendment of this Agreement that changes the amount or the form of the consideration to be delivered under this Agreement to the holders of Company Common Stock, or which by applicable Law or in accordance with the rules of any stock exchange requires the further approval of the stockholders of the Company or Parent without such further approval of such stockholders, or (b) any amendment or change not permitted under applicable Law. This Agreement may not be amended except by an instrument in writing signed by each of the parties hereto.

Section 8.5 Waiver. At any time prior to the Effective Time, subject to applicable Law, any party hereto may (a) extend the time for the performance of any obligation

or other act of any other party hereto, (b) waive any inaccuracy in the representations and warranties of the other party contained herein or in any document delivered pursuant hereto, and (c) subject to the proviso of Section 8.4, waive compliance with any agreement or condition contained herein. Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in an instrument in writing signed by the party or parties to be bound thereby. Notwithstanding the foregoing, no failure or delay by the Company, Parent or Merger Sub in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise of any other right hereunder.

Section 8.6 Fees and Expenses. Except as otherwise provided in this Agreement, all Expenses incurred in connection with this Agreement and the transactions contemplated by this Agreement shall be paid by the party incurring such expenses, whether or not the transactions contemplated by this Agreement are consummated; provided, however, that the Company and Parent shall share equally all Expenses related to the printing and filing of the Form S-4 and the printing, filing and distribution of the Joint Proxy Statement, other than attorneys’ and accountants’ fees.

Section 9.3 Interpretation; Certain Definitions. The parties hereto have participated jointly in the negotiation and drafting of this Agreement. Consequently, in the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement. When a reference is made in this Agreement to an Article, Section, Appendix or Exhibit, such reference shall be to an Article or Section of, or an Appendix or Exhibit to, this Agreement, unless otherwise indicated. The table of contents and headings for this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereof,” “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. All terms defined in this Agreement shall have the defined meanings when used in any certificate or other instrument made or delivered pursuant hereto unless otherwise defined therein. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to the feminine and neuter genders of such term. Any Law defined or referred to herein or in any agreement or instrument that is referred to herein means

100

such Law as from time to time amended, modified or supplemented, including (in the case of statutes) by succession of comparable successor Laws. References to a person are also to its successors and permitted assigns. All references to “dollars” or “$” refer to currency of the United States of America.

Section 9.4 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced under any present or future Law, or public policy, (a) such term or other provision shall be fully separable, (b) this Agreement shall be construed and enforced as if such invalid, illegal or unenforceable provision had never comprised a part hereof, and (c) all other conditions and provisions of this Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable term or other provision or by its severance herefrom so long as the economic or legal substance of the transactions contemplated by this Agreement is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that transactions contemplated by this Agreement be consummated as originally contemplated to the fullest extent possible.

Section 9.5 Assignment; Delegation. Neither this Agreement nor any rights, interests or obligations hereunder shall be assigned or delegated, in whole or in part, by any of the parties hereto (whether by operation of Law or otherwise) without the prior written consent of the other parties hereto (except to the Surviving Entity).

Section 9.6 Entire Agreement. This Agreement (including the exhibits, annexes and appendices hereto) constitutes, together with the Confidentiality Agreement, the entire agreement between the parties with respect to the subject matter hereof and thereof and supersedes all prior agreements and understandings, both written and oral, among the parties, or any of them, with respect to the subject matter hereof and thereof.

Section 9.7 No Third-Party Beneficiaries. This Agreement is not intended to and shall not confer any rights or remedies upon any person other than the parties hereto and their respective successors and permitted assigns, except for the provisions of Section 6.9. The representations and warranties in this Agreement are the product of negotiations among the parties hereto and are for the sole benefit of the parties hereto. Any inaccuracies in such representations and warranties are subject to waiver by the parties hereto in accordance with Section 8.5 without notice or liability to any other person. The representations and warranties in this Agreement may represent an allocation among the parties hereto of risks associated with particular matters regardless of the knowledge of any of the parties hereto. Accordingly, persons other than the parties hereto may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.

Section 9.8 Specific Performance. The parties hereto agree that irreparable damage, for which monetary damages (even if available) would not be an adequate remedy, would occur in the event that the parties hereto do not perform the provisions of this Agreement (including failing to take such actions as are required of it hereunder to consummate the Merger

101

and the other transactions contemplated by this Agreement) in accordance with its specified terms or otherwise breach such provisions. Accordingly, the parties acknowledge and agree that the parties shall be entitled to an injunction, specific performance and other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof, in addition to any other remedy to which they are entitled at Law or in equity. Each of the parties agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief on the basis that any other party has an adequate remedy at Law or that any award of specific performance is not an appropriate remedy for any reason at Law or in equity. Any party seeking an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement shall not be required to provide any bond or other security in connection with any such order or injunction.

Section 9.9 Counterparts. This Agreement may be executed in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by facsimile transmission or by e-mail of a pdf attachment shall be effective as delivery of a manually executed counterpart of this Agreement.

Section 9.10 Governing Law. This Agreement and all actions, proceedings or counterclaims (whether based on contract, tort or otherwise) directly or indirectly arising out of or relating to this Agreement or the actions of Parent, Merger Sub or the Company in the negotiation, administration, performance and enforcement thereof, shall be governed by, and construed in accordance with, the laws of the State of Maryland, without giving effect to any choice or conflict of Laws provision or rule (whether of the State of Maryland or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Maryland.

Section 9.11 Consent to Jurisdiction.

(a) Each of the parties hereto hereby irrevocably submits to the exclusive jurisdiction of the courts of the State of Maryland and to the jurisdiction of the United States District Court for the State of Maryland, for the purpose of any action, proceeding or counterclaim (whether based on contract, tort or otherwise) directly or indirectly arising out of or relating to this Agreement or the actions of the parties hereto in the negotiation, administration, performance and enforcement thereof, and each of the parties hereto hereby irrevocably agrees that all claims in respect to such action or proceeding may be heard and determined exclusively in any Maryland state or federal court.

(b) Each of the parties hereto (i) irrevocably consents to the service of the summons and complaint and any other process in any other action or proceeding relating to the transactions contemplated by this Agreement, on behalf of itself or its property, by personal delivery of copies of such process to such party and nothing in this Section 9.11 shall affect the right of any party to serve legal process in any other manner permitted by Law, (ii) consents to submit itself to the personal jurisdiction of any United States federal court located in the State of

102

Each of Parent, Merger Sub and the Company agrees that a final judgment in any action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law.

EACH OF THE PARTIES HERETO ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE OUT OF OR RELATING TO THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY, OR THE ACTIONS OF THE PARTIES HERETO IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT THEREOF. EACH OF THE PARTIES HERETO CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (B) EACH SUCH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (C) EACH SUCH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (D) EACH SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.12.
