STAR or SIR, as applicable, shall be entitled to deduct and withhold such amounts as may be required to be deducted and withheld under the Code and any applicable state or local Tax laws with respect to the lapsing of any restrictions on Restricted SIR Share Awards pursuant to this Section 3.2(a).

(a)    Prior to the Merger Effective Time, STAR shall appoint DST Systems, Inc. as the exchange agent (or any successor exchange agent for SIR, (the “Exchange Agent”) to act as the agent for the purpose of paying the Merger Consideration for the Book-Entry Shares. At or promptly following the Merger Effective Time, STAR shall deposit with the Exchange Agent for the sole benefit of the holders of shares of SIR Common Stock, for exchange in accordance with this Article 3, Book-Entry shares representing shares of STAR Common Stock to be issued pursuant to Section 3.1(a)(i) equal to the aggregate Merger Consideration (the “Exchange Fund”). In addition to the foregoing, after the Merger Effective Time on the appropriate payment date, if applicable, STAR shall provide or shall cause to be provided to the Exchange Agent any dividends or other distributions payable on such shares of STAR Common Stock, with both a record and payment date after the Merger Effective Time and prior to the surrender of the SIR Common Stock in exchange for the Merger Consideration, pursuant to Section 3.3(d), such dividends or other distributions shall be deemed to be part of the Exchange Fund. STAR shall cause the Exchange Agent to make, and the Exchange Agent shall make delivery of, the Merger Consideration out of the Exchange Fund in accordance with this Agreement.

17

Letter of Transmittal or (B) receipt of an “agent’s message” by the Exchange Agent (or such other evidence, if any, of transfer as the Exchange Agent may reasonably request) in the case of transfer of a Book-Entry Share, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Book-Entry Share representing shares of SIR Common Stock shall be entitled to receive in exchange therefor (i) the Merger Consideration into which such shares of SIR Common Stock shall have been converted pursuant to this Agreement and (ii) certain dividends and distributions in accordance with Section 3.3(a) and Section 3.3(d), if any, after the Exchange Agent’s receipt of such Book-Entry Share or “agent’s message” or other evidence, and the Book-Entry Share so transferred shall be forthwith cancelled. The Exchange Agent shall accept such Book-Entry Shares upon compliance with such reasonable terms and conditions as the Exchange Agent may impose to effect an orderly exchange thereof in accordance with customary exchange practices. Until surrendered or transferred as contemplated by this Section 3.3, each Book-Entry Share representing shares of SIR Common Stock shall be deemed, at any time after the Merger Effective Time to represent only the right to receive, upon such surrender, the Merger Consideration as contemplated by this Article 3.

(d)    No dividends or other distributions declared or made after the Merger Effective Time with respect to STAR Common Stock with a record date after the Merger Effective Time shall be paid to any holder entitled by reason of the Merger to receive Book-Entry shares representing STAR Common Stock until such holder shall have transferred its Book-Entry Share pursuant to this Section 3.3. Subject to applicable Law, following surrender of any such Book-Entry shares, such holder shall be paid, in each case, without interest, (i) the amount of any dividends or other distributions theretofore paid with respect to the shares of STAR Common Stock represented by the Book-Entry shares received by such holder and having a record date on or after the Merger Effective Time and a payment date prior to such surrender and (ii) at the appropriate payment date or as promptly as practicable thereafter, the amount of any dividends or other distributions payable with respect to such shares of STAR Common Stock and having a record date on or after the Merger Effective Time but prior to such surrender and a payment date on or after such surrender.

(e)    In the event of a transfer of ownership of shares of SIR Common Stock that is not registered in the transfer records of SIR, it shall be a condition of payment that any Book-Entry Share transferred in accordance with the procedures set forth in this Section 3.3 shall be properly endorsed or shall be otherwise in proper form for transfer, and that the Person requesting such payment shall have paid any Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of the Book-Entry Share transferred or shall have established to the reasonable satisfaction of STAR that such Tax either has been paid or is not applicable.

(f)    Any portion of the Exchange Fund that remains undistributed to the holders of SIR Common Stock for six (6) months after the Merger Effective Time shall be delivered to STAR upon demand, and any former holders of SIR Common Stock prior to the Merger who have not theretofore complied with this Article 3 shall thereafter look only to STAR for payment of their claims (as general conditions) with respect thereto.

18

(g)    None of the STAR Parties, the SIR Parties, the Surviving Entity, the Exchange Agent, or any employee, officer, director, agent or Affiliate of such entities, shall be liable to any Person in respect of the Merger Consideration if the Exchange Fund (or the appropriate portion thereof) has been delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. Any amounts remaining unclaimed by holders of any shares of SIR Common Stock 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 STAR free and clear of any claims or interest of such holders or their successors, assigns or personal representatives previously entitled thereto.

Section 4.13    Taxes.

(a)    Each SIR Party and each other SIR Subsidiary has timely filed with the appropriate Governmental Authority all United States federal income Tax Returns and all other material Tax Returns required to be filed, taking into account any extensions of time within which to file such Tax Returns, and all such Tax Returns were complete and correct in all material respects. Each SIR Party and each other SIR Subsidiary has duly paid (or there has been paid on their behalf), or made adequate provisions in accordance with GAAP for, all material Taxes required to be paid by them, whether or not shown on any Tax Return. True and materially complete copies of all United States federal income Tax Returns that have been filed with the IRS by SIR and each SIR Subsidiary with respect to the taxable years ending on or after December 31, 2015 have been made available to STAR. No written claim has been proposed by any Governmental Authority in any jurisdiction where SIR or any SIR Subsidiary do not file Tax Returns that SIR or any SIR Subsidiary is or may be subject to Tax by such jurisdiction.

(b)    Beginning with its initial taxable year ending on December 31, 2010, and through and including the Closing Date (determined as if SIR’s current taxable year ended immediately prior to Closing), SIR (i) has been organized and operated in conformity with the requirements to qualify as a REIT under the Code and the current and proposed method of operation for SIR is expected to enable SIR to continue to meet the requirements for qualification as a REIT through and including the Closing Date, and (ii) has not taken or omitted to take any action which would reasonably be expected to result in SIR’s failure to qualify as a REIT, and no challenge to SIR’s status as a REIT is pending or threatened in writing. No SIR Subsidiary is a corporation for United States federal income tax purposes, other than a corporation that qualifies as a Qualified REIT Subsidiary or as a Taxable REIT Subsidiary. SIR’s dividends paid deduction, within the meaning of Section 561 of the Code, for each taxable year, taking into account any dividends subject to Sections 857(b)(8) or 858 of the Code, has not been less than the sum of (i) SIR’s REIT taxable income, as defined in Section 857(b)(2) of the Code, determined without regard to any dividends paid deduction for such year and (ii) SIR’s net capital gain for such year.

(c)    (i) There are no audits, investigations by any Governmental Authority or other proceedings pending or, to the Knowledge of SIR, threatened with regard to any material Taxes or Tax Returns of SIR or any SIR Subsidiary; (ii) no material deficiency for Taxes of SIR or any SIR Subsidiary has been claimed, proposed or assessed in writing or, to the Knowledge of SIR, threatened, by any Governmental Authority, which deficiency has not yet been settled except for such deficiencies which are being contested in good faith or with respect to which the failure to pay, individually or in the aggregate, would not reasonably be expected to have a SIR Material Adverse Effect; (iii) neither SIR nor any SIR Subsidiary has waived any statute of limitations with respect to the assessment of material Taxes or agreed to any extension of time with respect to any material Tax assessment or deficiency for any open tax year; (iv) neither SIR nor any SIR Subsidiary is currently the beneficiary of any extension of time within which to file any material Tax Return; and (v) neither SIR nor any SIR Subsidiary has entered into any “closing agreement” as described in Section 7121 of the Code (or any corresponding or similar provision of state, local or foreign income Tax Law).

(d)    Each SIR Subsidiary that is a partnership, joint venture or limited liability company and that has not elected to be a Taxable REIT Subsidiary has been since its formation treated for United States federal income tax purposes as a partnership, disregarded entity, or Qualified REIT Subsidiary, as the case may be, and not as a corporation, an association taxable as a corporation whose separate existence is respected for United States federal income tax purposes, or a “publicly traded partnership” within the meaning of Section 7704(b) of the Code that is treated as a corporation for U.S. federal income tax purposes under Section 7704(a) of the Code.

33

(e)    Neither SIR nor any SIR Subsidiary holds any asset the disposition of which would be subject to Treasury Regulation Section 1.337(d)-7, nor have they disposed of any such asset during its current taxable year.

(f)    Since its inception, SIR and the SIR Subsidiaries have not incurred (i) any material liability for Taxes under Sections 857(b)(1), 857(b)(4), 857(b)(5), 857(b)(6)(A), 857(b)(7), 860(c) or 4981 of the Code, or Treasury Regulations Sections 1.337(d)-5, 1.337(d)-6, or 1.337(d)-7, (ii) any material liability for Taxes under Sections 857(b)(5) (for income test violations), 856(c)(7)(C) (for asset test violations), or 856(g)(5)(C) (for violations of other qualification requirements applicable to REITs) and (iii) SIR has not, and none of the SIR Subsidiaries have, incurred any material liability for Tax other than (A) in the ordinary course of business consistent with past practice, or (B) transfer or similar Taxes arising in connection with sales of property. No event has occurred, and to the Knowledge of SIR no condition or circumstances exists, which presents a material risk that any material liability for Taxes described clauses (i), (ii), or (iii) of the preceding sentence will be imposed upon SIR or any SIR Subsidiary.

(g)    SIR and the SIR Subsidiaries have complied, in all material respects, with all applicable Laws relating to the payment and withholding of Taxes (including withholding of Taxes pursuant to Sections 1441, 1442, 1445, 1446 and 3402 of the Code or similar provisions under any state and foreign Laws) and have duly and timely withheld and, in each case, have paid over to the appropriate taxing authorities all material amounts required to be so withheld and paid over on or prior to the due date thereof under all applicable Laws.

(h)    There are no SIR Tax Protection Agreements (as hereinafter defined) in force at the date of this Agreement (other than customary Tax indemnification provisions in commercial Contracts not primarily relating to Taxes), and, as of the date of this Agreement, no person has raised in writing, or to the Knowledge of SIR threatened to raise, a material claim against SIR or any SIR Subsidiary for any breach of any SIR Tax Protection Agreements. As used herein, “SIR Tax Protection Agreements” means any written agreement to which SIR or any SIR Subsidiary is a party pursuant to which: (i) any liability to holders of limited partnership interests in a SIR Subsidiary Partnership (as hereinafter defined) relating to Taxes may arise, whether or not as a result of the consummation of the transactions contemplated by this Agreement; and/or (ii) in connection with the deferral of income Taxes of a holder of limited partnership interests or limited liability company interests in a SIR Subsidiary Partnership, SIR or any SIR Subsidiary has agreed to (A) maintain a minimum level of debt, continue a particular debt or provide rights to guarantee debt, (B) retain or not dispose of assets, (C) make or refrain from making Tax elections, and/or (D) only dispose of assets in a particular manner. As used herein, “SIR Subsidiary Partnership” means a SIR Subsidiary that is a partnership for United States federal income tax purposes.

(i)    There are no Tax Liens upon any property or assets of SIR or any SIR Subsidiary except Liens for Taxes not yet due and payable or that are being contested in good faith by appropriate proceedings and for which adequate reserves have been established in accordance with GAAP.

34

(j)    There are no Tax allocation or sharing agreements or similar arrangements with respect to or involving SIR or any SIR Subsidiary, and after the Closing Date neither SIR nor any SIR Subsidiary shall be bound by any such Tax allocation agreements or similar arrangements or have any liability thereunder for amounts due in respect of periods prior to the Closing Date.

(k)    Neither SIR nor any SIR Subsidiary has requested or received any private letter ruling or other similar written ruling of a Governmental Authority or entered into any written agreement with a Governmental Authority with respect to any Taxes, and neither SIR nor any SIR Subsidiary is subject to any such private letter ruling or other similar written ruling of a Governmental Authority.

(l)    Neither SIR nor any SIR Subsidiary (i) has been a member of an affiliated group filing a consolidated federal income Tax or (ii) has any liability for the Taxes of any Person (other than any SIR Subsidiary) under Treasury Regulation Section 1.1502-6 (or any similar provision of state, local or foreign law), as a transferee or successor, by Contract, or otherwise.

(m)    Neither SIR nor any SIR Subsidiary has participated in any “listed transaction” within the meaning of Treasury Regulation Section 1.6011-4(b)(2).

(o)    No written power of attorney that has been granted by SIR or any SIR Subsidiary (other than to SIR or a SIR Subsidiary) currently is in force with respect to any matter relating to Taxes.

Neither SIR nor any SIR Subsidiary: (a) owns any registered trademarks, patents or copyrights, (b) has any pending applications, registrations or recordings for any trademarks, patents or copyrights or (c) is a party to any Contracts with respect to use by SIR or any SIR Subsidiary of any trademarks or patents. Except as, individually or in the aggregate, would not reasonably be expected to have a SIR Material Adverse Effect, (i) no Intellectual Property used by SIR or any SIR Subsidiary infringes or is alleged to infringe any Intellectual Property rights of any third party, (ii) no Person is misappropriating, infringing or otherwise violating any Intellectual Property of SIR or any SIR Subsidiary, and (iii) SIR and the SIR Subsidiaries own or are licensed to use, or otherwise possess valid rights to use, all Intellectual Property necessary to conduct the business of SIR and the SIR Subsidiaries as it is currently conducted.

True and materially complete copies of all United States federal income Tax Returns that have been filed with the IRS by STAR and each STAR Subsidiary with respect to the taxable years ending on or after December 31, 2015 have been made available to SIR. No written claim has been proposed by any Governmental Authority in any jurisdiction where STAR or any STAR Subsidiary do not file Tax Returns that STAR or any STAR Subsidiary is or may be subject to Tax by such jurisdiction.

(b)    Beginning with its initial taxable year ending on December 31, 2014, and through and including the Closing Date (determined as if STAR’s current taxable year ended immediately prior to Closing), STAR (i) has been organized and operated in conformity with the requirements to qualify as a REIT under the Code and the current and proposed method of operation for STAR is expected to enable STAR to continue to meet the requirements for qualification as a REIT through and including the Closing Date, and (ii) has not taken or omitted to take any action which would reasonably be expected to result in STAR’s failure to qualify as a REIT, and no challenge to STAR’s status as a REIT is pending or threatened in writing.

(d)    Each STAR Subsidiary that is a partnership, joint venture or limited liability company and that has not elected to be a Taxable REIT Subsidiary has been since its formation treated for United States federal income tax purposes as a partnership, disregarded entity, or Qualified REIT Subsidiary, as the case may be, and not as a corporation, an association taxable as a corporation whose separate existence is respected for United States federal income tax purposes, or a “publicly traded partnership” within the meaning of Section 7704(b) of the Code that is treated as a corporation for U.S. federal income tax purposes under Section 7704(a) of the Code.

No event has occurred, and to the Knowledge of STAR no condition or circumstances exists, which presents a material risk that any material liability for Taxes described clauses (i), (ii) or (iii) of the preceding sentence will be imposed upon STAR or any STAR Subsidiary.

53

(g)    STAR and the STAR Subsidiaries have complied, in all material respects, with all applicable Laws relating to the payment and withholding of Taxes (including withholding of Taxes pursuant to Sections 1441, 1442, 1445, 1446 and 3402 of the Code or similar provisions under any state and foreign Laws) and have duly and timely withheld and, in each case, have paid over to the appropriate taxing authorities all material amounts required to be so withheld and paid over on or prior to the due date thereof under all applicable Laws.

(j)    There are no Tax allocation or sharing agreements or similar arrangements with respect to or involving STAR or any STAR Subsidiary, and after the Closing Date neither STAR nor any STAR Subsidiary shall be bound by any such Tax allocation agreements or similar arrangements or have any liability thereunder for amounts due in respect of periods prior to the Closing Date.

(k)    Neither STAR nor any STAR Subsidiary has requested or received any private letter ruling or other similar written ruling of a Governmental Authority or entered into any written agreement with a Governmental Authority with respect to any Taxes, and neither STAR nor any STAR Subsidiary is subject to any such private letter ruling or other similar written ruling of a Governmental Authority.

Section 7.1    Preparation of the Form S-4 and the Proxy Statement; Stockholder Approval.

(a)    As promptly as reasonably practicable following the date of this Agreement, (i) SIR shall prepare (with STAR’s reasonable cooperation) and cause to be filed with the SEC the Proxy Statement in preliminary form with respect to the Stockholders Meeting and (ii) STAR shall prepare (with SIR’s reasonable cooperation) and cause to be filed with the SEC, a registration statement on Form S-4 under the Securities Act (the “Form S-4”), which will include the Proxy

68

Statement, to register under the Securities Act the shares of STAR Common Stock to be issued in the Merger, (together, the “Registered Securities”). Each of SIR and STAR shall use its reasonable best efforts to (A) have the Form S-4 declared effective under the Securities Act as promptly as practicable after such filing, (B) ensure that the Form S-4 complies in all material respects with the applicable provisions of the Exchange Act and the Securities Act and (C) keep the Form S-4 effective for so long as necessary to complete the Merger, unless this Agreement is terminated pursuant to Article 9. Each of SIR and STAR shall furnish all information concerning itself, its Affiliates and the holders of its capital stock to the other Party and provide such other assistance as may be reasonably requested in connection with the preparation, filing and distribution of the Form S-4 and the Proxy Statement and shall provide to their and each other’s counsel such representations as reasonably necessary to render the opinions required to be filed therewith. The Form S-4 and the Proxy Statement shall include all information reasonably requested by such other Party to be included therein. Each of SIR and STAR shall promptly notify the other Party 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 the Proxy Statement, and shall, as promptly as practicable after receipt thereof, provide the other Party with copies of all correspondence between it and its Representatives, on the one hand, and the SEC, on the other hand, and all written comments with respect to the Form S-4 or the Proxy Statement received from the SEC and advise the other Party of any oral comments with respect to the Form S-4 or the Proxy Statement received from the SEC. Each of SIR and STAR shall use its reasonable best efforts to respond as promptly as practicable to any comments from the SEC with respect to the Form S-4 or the Proxy Statement. Notwithstanding the foregoing, prior to filing the Form S-4 (or any amendment or supplement thereto) with the SEC, mailing the Proxy Statement (or any amendment or supplement thereto) or responding to any comments of the SEC with respect thereto, each of SIR and STAR, as applicable, shall cooperate and provide the other Party a reasonable opportunity to review and comment on such document or response (including the proposed final version of such document or response) and shall give due consideration to all reasonable comments provided by the other Party. STAR shall notify SIR, 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 for offering or sale in any jurisdiction of the Registered Securities, and STAR shall use its reasonable best efforts to have any such stop order or suspension lifted, reversed or otherwise terminated. STAR shall also use its reasonable best efforts to take any other action required to be taken under the Securities Act, the Exchange Act, any applicable foreign or state securities or “blue sky” Laws and the rules and regulations thereunder in connection with the issuance of the Registered Securities, and SIR shall furnish all information concerning SIR and its stockholders as may be reasonably requested in connection with any such actions.

(b)    If, at any time prior to the receipt of the Stockholder Approval, any information relating to STAR or SIR, or any of their respective Affiliates, should be discovered by STAR or SIR which, in the reasonable judgment of STAR or SIR, should be set forth in an amendment of, or a supplement to, any of the Form S-4 or the 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 the light of the circumstances under which they were made, not misleading, the Party that discovers such information shall promptly notify the other Parties, and STAR and SIR shall cooperate in the prompt filing with the SEC of any necessary amendment of, or supplement to, the Form S-4 or the Proxy Statement and, to the extent required

69

by Law, in disseminating the information contained in such amendment or supplement to stockholders of STAR and SIR. Nothing in this Section 7.1(b) shall limit the obligations of any Party under Section 7.1(a). For purposes of Section 5.24, Section 4.22 and this Section 7.1, any information concerning or related to SIR, its Affiliates or the Stockholders Meeting will be deemed to have been provided by SIR, and any information concerning or related to STAR or its Affiliates will be deemed to have been provided by STAR.

(c)    As promptly as practicable following the date of this Agreement, SIR shall, in accordance with applicable Law and the SIR Governing Documents, establish a record date for, duly call, give notice of, convene and hold the Stockholders Meeting solely for the purpose of obtaining the Stockholder Approval (and other matters that shall be submitted to the holders of SIR Common Stock at such meeting); provided, that such record date shall not be more than ninety (90) days prior to the date of the Stockholders Meeting. SIR shall use its reasonable best efforts to cause the definitive Proxy Statement to be mailed to SIR’s stockholders entitled to vote at the Stockholders Meeting and to hold the Stockholders Meeting as soon as practicable after the Form S-4 is declared effective under the Securities Act (provided that there are no outstanding SEC comments on the Proxy Statement and the SEC has not otherwise enjoined mailing or use of the Proxy Statement). SIR shall, through the SIR Special Committee and the SIR Board, recommend to its stockholders that they provide the Stockholder Approval, include the SIR Special Committee and SIR Board Recommendation in the Proxy Statement and solicit and use its reasonable best efforts to obtain the Stockholder Approval, except to the extent that the SIR Special Committee and SIR Board shall have made an Adverse Recommendation Change as permitted by Section 7.3(c). Notwithstanding the foregoing provisions of this Section 7.1(c), if, on a date for which the Stockholders Meeting is scheduled, SIR has not received proxies representing a sufficient number of shares of SIR Common Stock to obtain the Stockholder Approval, whether or not a quorum is present, SIR shall have the right to make one or more successive postponements or adjournments of the Stockholders Meeting (provided, however, that the Stockholders Meeting shall not be postponed or adjourned to a date that is (i) more than thirty (30) days after the date for which the Stockholders Meeting was originally scheduled (excluding any adjournments or postponements required by applicable Law)) or (ii) more than one hundred twenty (120) days from the record date for the Stockholders Meeting; provided, further, the Stockholders Meeting may not be postponed or adjourned on the date the Stockholders Meeting is scheduled if SIR shall have received proxies in respect of an aggregate number of shares of SIR Common Stock, which have not been withdrawn, such that Stockholder Approval would be obtained at such meeting.

Section 7.2    Access to Information; Confidentiality.

(a)    During the period from the date of this Agreement to and including the Merger Effective Time, each of the Parties shall, and shall cause each of their respective subsidiaries to, afford to the other Parties and to their respective Representatives reasonable access during normal business hours and upon reasonable advance notice to all of their respective properties, offices, books, Contracts, personnel and records that the other Party may reasonably request and, during such period, each of the Parties shall, and shall cause each of their respective subsidiaries to and shall use their reasonable best efforts to cause its Representatives to, furnish reasonably promptly to the other Parties (i) any information concerning such Party or its respective subsidiaries (including with respect to any pending or threatened Action) as the other Party may

70

reasonably request and (ii) 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. In connection with such reasonable access to information, each of the Parties shall use their reasonable best efforts to cause its respective Representatives to participate in meetings and telephone conferences with the other Parties and their Representatives prior to the mailing of the Proxy Statement, prior to the Stockholders Meeting, respectively, and at such other times as may be reasonably requested. No investigation under this Section 7.2(a) or otherwise shall affect any of the representations and warranties of the Parties contained in this Agreement or any condition to the obligations of the Parties under this Agreement. Notwithstanding the foregoing, none of the Parties shall be required by this Section 7.2(a) to provide the other Parties or their respective Representatives with access to or to disclose information (A) 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 in accordance with this Agreement (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), (B) the disclosure of which would violate any Law applicable to such Party or any of its Representatives (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 duty), (C) that is subject to any attorney-client, attorney work product or other legal 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 any such attorney-client, attorney work product or other legal privilege, including by means of entry into a customary joint defense agreement that would alleviate the loss of such privilege) or (D) for the purpose of allowing Parties or their respective Representatives to collect samples of soil, air, water, groundwater or building materials. The Parties will use their reasonable best efforts to minimize any disruption to the businesses of the other Parties and any of their respective subsidiaries that may result from the requests for access, data and information hereunder. Prior to the Merger Effective Time, the Parties shall not, and shall cause their respective Representatives and Affiliates not to, contact or otherwise communicate with parties with which any of the other Parties or any other of their respective subsidiaries has a business relationship regarding the business of the other Parties and their respective subsidiaries or this Agreement and the transactions contemplated by this Agreement without the prior written consent of such other Party (provided, that, for the avoidance of doubt, nothing in this Section 7.2(a) shall be deemed to restrict the Parties from contacting such parties in pursuing the business of the Parties operating in the ordinary course).

(b)    Each Party will hold, and will cause its respective Representatives and Affiliates to hold, any nonpublic information, including any information exchanged pursuant to this Section 7.2, in confidence to the extent required by and in accordance with, and will otherwise comply with, the terms of the Confidentiality Agreements, which shall remain in full force and effect pursuant to the terms thereof notwithstanding the execution and delivery of this Agreement or the termination thereof.

Section 7.3    No Solicitation of Transactions.

(a)    Notwithstanding anything to the contrary contained in this Agreement but subject to Section 7.3(e) and Section 7.3(f), during the period beginning on the date of this

71

Agreement and continuing until 11:59 p.m. (New York City time) on September 5, 2019 (the “Go Shop Period End Time”), SIR, the SIR Subsidiaries and their respective Representatives may and shall have the right to, directly or indirectly: (i) initiate, solicit, encourage or facilitate any inquiries or the making of any proposal, offer or other action that constitutes, or may reasonably be expected to lead to, any Acquisition Proposal, including by way of (A) contacting third parties, (B) broadly disseminating public disclosure or (C) providing access to the properties, offices, assets, books, records and personnel of SIR and the SIR Subsidiaries and furnishing non-public information pursuant to (but only pursuant to) one or more Acceptable Confidentiality Agreements; provided, however, that SIR shall prior to, or concurrently with the time such access or non-public information is provided, provide such access and make available such non-public information to STAR; (ii) enter into, continue or otherwise participate in any discussions or negotiations with any Person relating to, or in furtherance of such inquiries, proposals, offers or other actions or to obtain, an Acquisition Proposal; (iii) release any Person from, or refrain from enforcing, any standstill agreement or similar obligation to SIR or any of the SIR Subsidiaries; and (iv) disclose to the stockholders of SIR any information required to be disclosed under applicable Law; provided, however, that in the case of this clause (iv), to the extent the disclosure addresses the Merger or an Acquisition Proposal, the disclosure shall be deemed to be an Adverse Recommendation Change if the disclosure has the effect of withdrawing or adversely modifying, or is not accompanied by an express public affirmation of the SIR Board Recommendation. For purposes of this Agreement, the term “Go Shop Bidder” shall mean any Person (including its controlled Affiliates and Representatives) that submits a written proposal or offer regarding an Acquisition Proposal prior to the Go Shop Period End Time that has not been withdrawn and that the SIR Special Committee determines, in good faith, after consultation with its financial advisors and outside legal counsel, prior to the Go Shop Period End Time (or in the case of any Acquisition Proposal received less than five (5) Business Days before the date of the Go Shop Period End Time, not later than five (5) Business Days after the receipt of such Acquisition Proposal), has resulted in, or would be reasonably expected to result in, a Superior Proposal (as defined below) (such Person, a “Go Shop Bidder”); provided, that a Go Shop Bidder shall cease to be a Go Shop Bidder if (1) the negotiations between SIR and such Go Shop Bidder with respect to the Acquisition Proposal that resulted in such Go Shop Bidder becoming a Go Shop Bidder shall have been terminated, (2) the Acquisition Proposal submitted by such Go Shop Bidder prior to the Go Shop Period End Time is withdrawn, terminated or modified in a manner such that, in the SIR Special Committee’s good faith determination, after consultation with its financial advisors and outside legal counsel, the Acquisition Proposal as modified no longer constitutes, or would no longer reasonably be expected to lead to, a Superior Proposal, or (3) such Go Shop Bidder otherwise ceases to be actively pursuing efforts to acquire SIR or the SIR Operating Partnership. No later than forty-eight (48) hours after the Go Shop Period End Time (or after a bidder is determined to be a Go Shop Bidder if such determination occurs after the Go Shop Period End Time), SIR shall notify STAR in writing (I) if any Go Shop Bidders remain at such time, (II) of the identity of such Go Shop Bidder(s) and (III) the material terms and conditions of the most recent Acquisition Proposal received from such Go Shop Bidder(s) (and shall include with such notice (x) copies of any written Acquisition Proposal, including any proposed transaction agreement and any related transaction documents and financing commitments, if any and (y) a written summary of the material terms of any related Acquisition Proposal not made in writing (including any material terms proposed orally or supplementally)), and thereafter shall promptly (and in any event no later than forty-eight (48) hours after the occurrence of such developments, discussions or negotiations or receipt of

72

materials) (1) keep STAR reasonably informed of all material developments, discussions and negotiations concerning any such Acquisition Proposal and (2) provide STAR with any written supplements or written additions to any written Acquisition Proposal, including any revisions to any proposed transaction agreement and any related transaction documents and financing commitments, if any. Without limiting the foregoing, from and after the Go Shop Period End Time, SIR will promptly (and in any event no later than forty-eight (48) hours after receipt thereof) notify STAR in writing if (A) any Acquisition Proposal is received by SIR or any SIR Subsidiary, (B) any request for information relating to SIR or any SIR Subsidiary is received by SIR or any SIR Subsidiary from any Person who informs SIR or any SIR Subsidiary that it is considering making or has made an Acquisition Proposal or (C) any discussions or negotiations are sought to be initiated with SIR or any SIR Subsidiary regarding any Acquisition Proposal, and shall, in any such notice to STAR, indicate the identity of the Person making, and the material terms and conditions of, such Acquisition Proposal, request or inquiry (and shall include with such notice (x) copies of any written Acquisition Proposal, including any proposed transaction agreement and any related transaction documents and financing commitments, if any, and (y) a written summary of the material terms of any related Acquisition Proposal not made in writing (including any material terms proposed orally or supplementally), and thereafter shall promptly (and in any event no later than forty-eight (48) hours after the occurrence of such developments, discussions or negotiations or receipt of materials) (1) keep STAR reasonably informed of all material developments, discussions and negotiations concerning any such Acquisition Proposal, request or inquiry and (2) provide STAR with any written supplements or written additions to any written Acquisition Proposal, including any revisions to any proposed transaction agreement and any related transaction documents and financing commitments, if any. Neither SIR nor any SIR Subsidiary will enter into any agreement with any Person subsequent to the date of this Agreement that prohibits SIR from providing any information to STAR in accordance with this Section 7.3.

(b)    Except as permitted by this Section 7.3, and except with respect to a Go Shop Bidder, from and after the Go-Shop Period End Time, SIR shall not, and shall cause each of the STAR Subsidiaries and its and their respective directors, officers and Affiliates, and shall direct each of its and the SIR Subsidiaries’ other Representatives (to the extent acting on behalf of SIR) not to, directly or indirectly, (i) initiate, solicit, knowingly encourage or facilitate any inquiries, proposals or offers for, or engage in any negotiations concerning, or provide any confidential or nonpublic information or data to, or have any discussions with, any Person relating to any inquiry, proposal, offer or other action that constitutes, or may reasonably be expected to lead to, any Acquisition Proposal, (ii) enter into or engage in, continue or otherwise participate in any discussions or negotiations with any Person regarding or otherwise in furtherance of, or furnish to any Person other than a STAR Party or its Representatives, any information in connection with or for the purpose of encouraging or facilitating any inquiry, proposal, offer or other action that constitutes, or could reasonably be expected to lead to, or to otherwise obtain an Acquisition Proposal, (iii) release any Person from or fail to enforce any confidentiality agreement, standstill agreement or similar obligation (provided that SIR shall be permitted to waive or to not enforce any provision of any confidentiality agreement, standstill agreement or similar obligation to permit a Person to make a confidential Acquisition Proposal directly to the SIR Special Committee if the SIR Special Committee determines in good faith after consultation with outside legal counsel that any such failure to waive or to not enforce would be inconsistent with or otherwise result in a breach of the SIR directors’ duties under applicable Law), (iv) enter into any agreement in

73

principle, arrangement, understanding, contract or agreement (whether binding or not) contemplating or otherwise relating to an Acquisition Proposal, or (v) take any action to exempt any Person from any Takeover Statute or similar restrictive provision of the SIR Organizational Documents. In furtherance of the foregoing and except with respect to a Go Shop Bidder and as otherwise permitted by this Section 7.3, SIR shall, and shall cause each SIR Subsidiary and each Representative of SIR and the SIR Subsidiaries to, immediately cease any discussions, negotiations or communications with any Person with respect to any Acquisition Proposal or potential Acquisition Proposal and shall immediately terminate all physical and electronic data room access previously granted to any such Person and exercise and use reasonable best efforts to enforce any contractual rights available to SIR to cause such Person to return or destroy all non-public information concerning SIR and the SIR Subsidiaries to the extent permitted pursuant to any confidentiality agreement with such Person and immediately terminate all physical and electronic data room access granted to such Person. For the avoidance of doubt, after the Go Shop Period End Time and until the receipt of Stockholder Approval, SIR, the SIR Subsidiaries and their respective Representatives may continue to take any of the actions described in Section 7.3(a) with respect to any proposals or offers regarding any Acquisition Proposal submitted by a Go Shop Bidder on or before the Go Shop Period End Time or with respect to any amended or modified proposal or offer with respect to any such Acquisition Proposal submitted by a Go Shop Bidder after the Go Shop Period End Time that SIR discloses to STAR (and provides copies to STAR of) if the SIR Special Committee has determined in good faith after consultation with outside legal counsel and outside financial advisors that such Acquisition Proposal (as may be amended or modified) is or is reasonably likely to lead to a Superior Proposal.

(c)    Notwithstanding anything in this Agreement to the contrary, at any time after the Go Shop Period End Time and prior to the time, but not after, Stockholder Approval is obtained, SIR and its Representatives may (i) provide information in response to a request therefor by a person or persons who has made a written Acquisition Proposal that did not result from a breach of this Section 7.3 (provided that SIR (A) receives from the person or persons so requesting such information an executed Acceptable Confidentiality Agreement, and (B) as contemplated below, SIR discloses to STAR (and provides copies to STAR of) such written Acquisition Proposal and concurrently furnishes, makes available or provides access to any nonpublic information provided to such person or persons to the extent not previously so provided to STAR), and (ii) engage or participate in any discussions or negotiations with any person who has made such a written Acquisition Proposal, if and only to the extent that, in each such case referred to in clause (i) or (ii) above, the SIR Special Committee has either determined that such Acquisition Proposal constitutes a Superior Proposal or determined in good faith after consultation with outside legal counsel and outside financial advisors that such Acquisition Proposal could reasonably be expected to lead to a Superior Proposal. Neither SIR nor any of the SIR Subsidiaries shall, after the date of this Agreement, enter into any confidentiality agreement that would prohibit it from providing such information to STAR.

(d)    Except as expressly provided in Section 7.3(e), Section 7.3(f) and Section 9.1(c)(ii), neither the SIR Board, nor any committee thereof, nor any group of directors, formally or informally, shall: (i) change, withhold, withdraw, qualify or modify or publicly propose or announce or authorize or resolve to, or announce its intention to change, withhold, withdraw, qualify or modify, in each case in a manner adverse to STAR, the SIR Board

74

Recommendation, (ii) authorize, approve, endorse, declare advisable, adopt or recommend or propose to publicly authorize, approve, endorse, declare advisable, adopt or recommend, any Acquisition Proposal, (iii) authorize, cause or permit SIR or any SIR Subsidiary to enter into any Alternative Acquisition Agreement, or (iv) fail to make the SIR Board Recommendation or fail to include the SIR Board Recommendation in the Proxy Statement (any event described in clause (i), (ii) or this clause (iv), whether taken by the SIR Board or a committee thereof, an “Adverse Recommendation Change”).

(e)    Notwithstanding anything in this Agreement to the contrary, at any time after the date of this Agreement and before Stockholder Approval is obtained and subject to compliance with the provisions of this Section 7.3(e) in all material respects, if SIR receives an Acquisition Proposal (whether or not from a Go Shop Bidder) that did not result from a breach of this Section 7.3 (and such proposal is not withdrawn) and the SIR Special Committee determines that such Acquisition Proposal constitutes a Superior Proposal and, after consultation with outside legal counsel, that failure to effect an Adverse Recommendation Change in connection with such Superior Proposal or that failure to terminate this Agreement to enter into an Alternative Acquisition Agreement for such Superior Proposal would be inconsistent with the SIR directors’ duties under applicable Law, then the SIR Board (based on the recommendation of the SIR Special Committee) may effect an Adverse Recommendation Change, enter into an Alternative Acquisition Agreement relating to or implementing the Superior Proposal, and terminate this Agreement in accordance with Section 9.1(c)(ii); provided that the SIR Board may not take action contemplated by this Section 7.3(e) unless:

(i)    SIR has notified STAR in writing that the SIR Board intends to take such action at least five (5) Business Days in advance of effecting an Adverse Recommendation Change, which notice shall specify in reasonable detail the reasons for such action, a description of the material terms of the Superior Proposal and attach the most current version of such agreements (including any amendments, supplements or modifications) between SIR and the party making such Superior Proposal to such notice (a “SIR Change Notice”); and

(ii)    during the five (5) Business Day period following STAR’s receipt of a SIR Change Notice, SIR shall have offered to negotiate with and, if accepted, negotiated with and directed its outside financial and outside legal advisors to negotiate with STAR in good faith to make such adjustments to the terms and conditions of this Agreement such that the Superior Proposal ceases to constitute (in the good faith determination of the SIR Special Committee, after consultation with outside legal counsel and outside financial advisors) a Superior Proposal; provided, that any amendment, supplement or modification to any Acquisition Proposal shall be deemed a new Acquisition Proposal and SIR may not enter into any agreement relating to the Superior Proposal pursuant this Section 7.3(e) or make an Adverse Recommendation Change pursuant to this Section 7.3(e) or terminate this Agreement pursuant to Section 9.1(c)(ii) unless SIR has complied with the requirements of this Section 7.3(e) with respect to such new Acquisition Proposal including sending an additional SIR Change Notice (except that the new negotiation period under this Section 7.3(e)(ii) shall be three (3) Business Days instead of five (5) Business Days). Notwithstanding anything in this Section 7.3(e)(ii), neither

75

STAR’s acceptance nor rejection of SIR’s offer to negotiate pursuant to this Section 7.3(e)(ii) shall have any bearing on STAR’s right to terminate this Agreement pursuant to Section 9.1(d)(ii) herein.

(f)    Nothing in this Section 7.3 or elsewhere in this Agreement shall prevent the SIR Board or SIR, directly or indirectly, from (i) taking and disclosing to the stockholders of the SIR a position contemplated by Rule 14d-9 or Rule 14e-2(a) promulgated under the Exchange Act with respect to an Acquisition Proposal, making any required disclosure to the stockholders of SIR under applicable Law, including Rule 14d-9 promulgated under the Exchange Act or Item 1012(a) of Regulation M-A or (ii) making any disclosure to the stockholders of SIR if the SIR Board determines in good faith after consultation with its outside legal counsel (and based on the recommendation of the SIR Special Committee) that the failure to do so would be inconsistent with the duties of the SIR directors to SIR under applicable Law; provided, however, that to the extent any such disclosure addresses the approval, recommendation or declaration of advisability by the SIR Board with respect to this Agreement or an Acquisition Proposal, such disclosure shall be deemed to be an Adverse Recommendation Change if not accompanied by an express public affirmation of the SIR Board Recommendation.

(g)    Notwithstanding anything to the contrary contained in this Agreement, SIR shall not, and shall not permit any SIR Subsidiaries or any of its or their respective Affiliates or Representatives to, reimburse or agree to reimburse the fees or expenses of any Person (including any Go Shop Bidder or its Representatives) in connection with (or related to) an Acquisition Proposal (including, for the avoidance of doubt, in connection with any Acceptable Confidentiality Agreement) but excluding, for the avoidance of doubt, in connection with any acquisition agreement or merger with respect to a Superior Proposal entered into pursuant to this Section 7.3 and resulting in termination of this Agreement pursuant to Section 9.1(c).

(h)    SIR agrees that in the event any Representative of SIR or any SIR Subsidiary takes any action that, if taken by SIR would constitute a material violation of this Section 7.3, then SIR shall be deemed to be in violation of this Section 7.3 for all purposes of this Agreement.

(i)    For purposes of this Agreement:

(i)    “Acquisition Proposal” means any bona fide proposal or offer from any Person (other than STAR or any STAR Subsidiaries), whether in one transaction or a series of related transactions, relating to any (a) merger, consolidation, share exchange, business combination or similar transaction involving SIR or any SIR Subsidiary that would constitute a “significant subsidiary” (as defined in Rule 1-02 of Regulation S-X), (b) sale or other disposition, by merger, consolidation, share exchange, business combination or any similar transaction, of any assets of SIR or any significant SIR Subsidiaries representing 20% or more of the consolidated assets of SIR and the significant SIR Subsidiaries, taken as a whole, (c) issue, sale or other disposition by SIR or any SIR Subsidiaries of (including by way of merger, consolidation, share exchange, business combination or any similar transaction) securities (or options, rights or warrants to purchase, or securities convertible into, such securities) representing 20% or more of the

76

votes associated with the outstanding shares of SIR Common Stock, (d) tender offer or exchange offer in which any Person or “group” (as such term is defined under the Exchange Act) shall acquire beneficial ownership (as such term is defined in Rule 13d-3 under the Exchange Act), or the right to acquire beneficial ownership, of 20% or more of the votes associated with the outstanding shares of SIR Common Stock, (e) recapitalization, restructuring, liquidation, dissolution or other similar type of transaction with respect to SIR in which a third party shall acquire beneficial ownership of 20% or more of the outstanding shares of SIR Common Stock, or (f) transaction that is similar in form, substance or purpose to any of the foregoing transactions; provided, however, that the term “Acquisition Proposal” shall not include (i) the Merger or any of the other transactions contemplated by this Agreement, (ii) any merger, consolidation, business combination, reorganization, recapitalization or similar transaction solely among SIR and one or more of the SIR Subsidiaries or solely among the SIR Subsidiaries or (iii) was solicited by any SIR Party or their Representative in breach of this Agreement.

(ii)    “Superior Proposal” means a written Acquisition Proposal (except for purposes of this definition, the references in the definition of “Acquisition Proposal” to “20%” shall be replaced with “50%”) which the SIR Board (based on the recommendation of the SIR Special Committee) determines in its good faith judgment (after consultation with its outside legal and financial advisors and after taking into account (a) all of the terms and conditions of the Acquisition Proposal and this Agreement (as it may be proposed to be amended by STAR) and (b) the feasibility and certainty of consummation of such Acquisition Proposal on the terms proposed (taking into account all legal, financial, regulatory and other aspects of such Acquisition Proposal and conditions to consummation thereof) to be more favorable from a financial point of view to the stockholders of SIR (in their capacities as stockholders) than the Merger and the other transactions contemplated by this Agreement (as it may be proposed to be amended by STAR)).

Section 7.4    Public Announcements. Except with respect to any Adverse Recommendation Change or any action taken pursuant to, and in accordance with, Section 7.1 or Section 7.3, so long as this Agreement is in effect, the Parties shall 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 by this Agreement, and none of the Parties shall issue any such press release or make any such public statement or filing prior to obtaining the other Parties’ consent (which consent shall not be unreasonably withheld, delayed or conditioned); provided, 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 or Order if it is not possible to consult with the other Party before making any public statement with respect to this Agreement or any of the transactions contemplated by this Agreement. The Parties have agreed upon the form of a joint press release announcing the Merger and the execution of this Agreement, and shall make such joint press release no later than one (1) Business Day following the date on which this Agreement is executed.

77

Section 7.7    Indemnification; Directors’ and Officers’ Insurance.

(a)    Without limiting or being limited by the provisions of Section 7.7(b) and to the extent permitted by applicable Law, during the period commencing as of the Merger Effective Time and ending on the sixth (6^th) anniversary of the Merger Effective Time, STAR shall (and shall cause the Surviving Entity to): (i) indemnify, defend and hold harmless each Indemnified Party against and from any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement in connection with any Action to the extent such Action arises out of or pertains to (x) any action or omission or alleged action or omission in such Indemnified Party’s capacity as a manager, director, officer, partner, member, trustee, employee or agent of SIR or any of the SIR Subsidiaries, or (y) this Agreement or any of the transactions contemplated by this Agreement, including the Merger; and (ii) pay in advance of the final disposition of any such Action the expenses (including reasonable attorneys’ fees and any expenses incurred by any Indemnified Party in connection with enforcing any rights with respect to indemnification) of any Indemnified Party without the requirement of any bond or other security, in each case to the fullest extent permitted by Law, but subject to STAR’s or the Surviving Entity’s receipt of an undertaking by or on behalf of such Indemnified Party to repay such amount if it shall ultimately be determined that such Indemnified Party is not entitled to be indemnified. Notwithstanding anything to the contrary set forth in this Agreement, STAR or the Surviving Entity, as applicable, (i) shall not settle or compromise or consent to the entry of any judgment or otherwise seek termination with respect to any claim, action, suit or proceeding against or investigation of any Indemnified Party for which indemnification may be sought under this Section 7.7(a) without the Indemnified Party’s prior written consent (which consent may not be unreasonably withheld, delayed or conditioned) unless such settlement, compromise, consent or termination includes an unconditional release of such Indemnified Party from all liability arising out of such claim, action, suit, proceeding or investigation, (ii) shall not be liable for any settlement effected without its prior written consent (which consent shall not be unreasonably withheld, delayed or conditioned) and (iii) shall not have any obligation hereunder to any Indemnified Party to the extent that a court of competent jurisdiction shall determine in a final and non-appealable

80

order that such indemnification is prohibited by applicable Law, in which case the Indemnified Party shall promptly refund to STAR or the Surviving Entity the amount of all such expenses theretofore advanced pursuant hereto.

(b)    Without limiting the foregoing, and to the extent permitted by applicable Law, each of STAR and the Surviving Entity agree that, during the period commencing as of the Merger Effective Time and ending on the sixth (6^th) anniversary of the Merger Effective Time, all rights to indemnification and exculpation from liabilities for acts or omissions occurring at or prior to the Merger Effective Time, and advancement of expenses, now existing in favor of the current or former managers, directors, officers, partners, members, trustees, employees, agents, fiduciaries or other individuals of SIR or any of the SIR Subsidiaries (each an “Indemnified Party” and collectively, the “Indemnified Parties”) as provided in (i) the SIR Charter, the SIR Bylaws or, if applicable, similar organizational documents or agreements of any SIR Subsidiary (the “SIR Organizational Documents”) and (ii) indemnification agreements of SIR shall survive the Merger and shall continue in full force and effect in accordance with their terms. For a period of six (6) years following the Merger Effective Time, the organizational documents of the STAR and Surviving Entity and the organizational documents of any applicable STAR Subsidiary or SIR Subsidiary shall contain provisions no less favorable with respect to indemnification and limitations on liability of directors and officers than are set forth in the STAR Governing Documents or, if applicable, similar organizational documents or agreements of any STAR Subsidiary. The STAR Governing Documents provisions shall not be amended, repealed or otherwise modified for a period of six (6) years following the Merger Effective Time in any manner that would affect adversely the rights thereunder of individuals who, at or prior to the Merger Effective Time, were Indemnified Parties, unless such modification shall be required by applicable Law and then only to the minimum extent required by applicable Law.

(c)    To the extent that any Indemnified Party shall reasonably believe that representation by counsel designated by STAR or the Surviving Entity in connection with any action, suit, proceeding, investigation or inquiry results in a conflict of interest or if the Indemnified Party believes it has defenses additional to or different from those available to STAR or the Surviving Entity, such Indemnified Party shall have the right to employ such person’s own separate counsel, at STAR’s or the Surviving Entity’s expense; provided, however, that such separate counsel shall, to the extent consistent with its professional responsibilities, cooperate with STAR or the Surviving Entity and any counsel designated by STAR or the Surviving Entity.

(d)    STAR shall obtain an extended reporting period coverage under STAR’s directors’ and officers’ liability insurance policies or the substantial equivalent of such coverage (to be effective as of the Merger Effective Time) with a policy period of six (6) years after the Merger Effective Time, on prepaid and non-cancellable terms, for a cost not in excess of three times the current annual premiums for such insurance. STAR and the Surviving Entity shall not take any action to terminate or modify the terms of the extended reporting period coverage.

(e)    If STAR or the Surviving Entity or any of their respective successors or assigns (i) consolidates with or merges with or into any other Person and shall not be the continuing or surviving corporation, partnership or other entity of such consolidation or merger or (ii) liquidates, dissolves or winds-up, or transfers or conveys all or substantially all of its properties

81

and assets to any Person, then, and in each such case, proper provision shall be made so that the successors and assigns of STAR or the Surviving Entity, as applicable, assume the obligations set forth in this Section 7.7.

(f)    STAR shall cause the Surviving Entity to pay all reasonable expenses, including reasonable attorneys’ fees, that may be incurred by any Indemnified Party in enforcing the obligations provided in this Section 7.7.

(g)    The provisions of this Section 7.7 are intended to be for the express benefit of, and shall be enforceable by, each Indemnified Party (who are intended third party beneficiaries of this Section 7.7), his or her heirs and his or her personal representatives, shall be binding on all successors and assigns of STAR, SIR and the Surviving Entity and shall not be amended in a manner that is adverse to the Indemnified Party (including his or her successors, assigns and heirs) without the prior written consent of the Indemnified Party (including such successors, assigns and heirs) affected thereby. The exculpation and indemnification provided for by this Section 7.7 shall not be deemed to be exclusive of any other rights to which an Indemnified Party is entitled, whether pursuant to applicable Law, Contract or otherwise.

Section 7.8     Dividends.

(a)    In the event that a distribution with respect to the shares of SIR Common Stock permitted under the terms of this Agreement has a record date prior to the Merger Effective Time and has not been paid prior to the Closing Date, such distribution shall be paid to the holders of such shares of SIR Common Stock on the Closing Date immediately prior to the Merger Effective Time. In the event that a distribution with respect to the shares of STAR Common Stock permitted under the terms of this Agreement has a record date prior to the Merger Effective Time and has not been paid prior to the Closing Date, such distribution shall be paid to the holders of such shares of STAR Common Stock on the Closing Date immediately prior to the Merger Effective Time. SIR shall coordinate with STAR on the declaration, setting of record dates and payment dates of dividends on SIR Common Stock so that holders of SIR Common Stock (i) do not receive dividends on both SIR Common Stock and STAR Common Stock received in the Merger in respect of a single distribution period or fail to receive a dividend on either SIR Common Stock or STAR Common Stock received in the Merger in respect of a single distribution period or (ii) do not receive both a dividend permitted by the proviso to Section 6.2(b)(iii) on STAR Common Stock and a dividend permitted by the proviso to Section 6.1(b)(iii) on SIR Common Stock received in the Merger or fail to receive either a dividend permitted by the proviso to Section 6.2(b)(iii) on STAR Common Stock or a dividend permitted by the proviso to Section 6.1(b)(iii) on SIR Common Stock received in the Merger.

(b)    In the event that either SIR or STAR shall declare or pay any dividend or other distribution that is expressly permitted pursuant to the proviso at the end of Section 6.1(b)(iii) or Section 6.2(b)(iii), respectively, it shall notify the other Party at least twenty (20) days prior to the Closing Date, and such other Party shall be entitled to declare a dividend per share payable (i) in the case of SIR, to holders of SIR Common Stock, in an amount per share of SIR Common Stock equal to the product of (A) the dividend declared by STAR with respect to each share of STAR Common Stock by (B) the Exchange Ratio, and (ii) in the case of STAR, to holders of

STAR Common Stock, in an amount per share of STAR Common Stock equal to the quotient obtained by dividing (x) the dividend declared by SIR with respect to each share of SIR Common Stock by (y) the Exchange Ratio.

(c)    by SIR (with prior approval of the SIR Special Committee):

(i)    if a breach of any representation or warranty or failure to perform any obligation, covenant or agreement on the part of any of the STAR Parties set forth in this Agreement has occurred that would cause any of the conditions set forth in Section 8.1 or Section 8.3 not to be satisfied (a “STAR Terminating Breach”), which breach or failure to perform cannot be cured, or, if capable of cure, has not been cured by the earlier of twenty (20) days following written notice thereof from SIR to STAR and two (2) Business Days before the Outside Date; provided, that SIR shall not have the right to terminate this Agreement pursuant to this Section 9.1(c)(i) if a SIR Terminating Breach shall have occurred and be continuing at the time SIR delivers notice of its election to terminate this Agreement pursuant to this Section 9.1(c)(i);

Section 9.2    Effect of Termination. In the event of termination of this Agreement as provided in Section 9.1, written notice thereof shall forthwith be given to the other Parties, in accordance with the provisions of Section 10.2, specifying the provision hereof pursuant to which such termination is made, and this Agreement shall forthwith become void and have no effect, without any liability or obligation on the part of the STAR Parties or the SIR Parties, except that the Confidentiality Agreements and the provisions of Section 7.4 (Public Announcements), this Section 9.2, Section 9.3 (Fees and Expenses), Section 9.4 (Amendment), and Article 10 (General Provisions) of this Agreement shall survive the termination hereof; provided, that no such termination shall relieve any Party from any liability or damages resulting from any fraud or willful and material breach of any of its covenants, obligations or agreements set forth in this Agreement.

Section 9.3    Fees and Expenses.

(a)    Except as otherwise provided in this Section 9.3, all Expenses shall be paid by the party incurring such fees or expenses, whether or not the Merger is consummated; provided that the Parties will share equally any Form S-4 filing fees as may be required to consummate the transactions contemplated by this Agreement.

(b)    In the event that this Agreement is terminated:

(i)    (A) by STAR pursuant to Section 9.1(d)(i), on account of a failure to perform any obligation, covenant or agreement on the part of any of the SIR Parties set forth in this Agreement, and after the date hereof and prior to the failure to perform giving rise to such right of termination, an Acquisition Proposal (with, for all purposes of this Section 9.3(b)(i), all percentages included in the definition of “Acquisition Proposal” increased to 50%) has been publicly announced, disclosed or otherwise communicated to the STAR Board or any Person shall have publicly announced an intention (whether or not conditional) to make such an Acquisition Proposal or (B)(x) by SIR pursuant to Section 9.1(b)(i) or Section 9.1(b)(iii), and after the date of this Agreement but prior to the Stockholders Meeting, an Acquisition Proposal with respect to SIR has been publicly announced, disclosed or otherwise communicated to SIR’s stockholders (and not withdrawn) or any Person shall have publicly announced an intention (whether or not conditional) to make such an Acquisition Proposal and (y) within twelve (12) months after

90

the date of such termination, a transaction in respect of the applicable Acquisition Proposal with respect to SIR is consummated or SIR enters into a definitive agreement in respect of the applicable Acquisition Proposal with respect to SIR that is later consummated, SIR shall pay to STAR (x) the Full Termination Payment and (y) up to $2,000,000 as reimbursement for STAR’s Expenses;

(ii)    by SIR pursuant to Section 9.1(c)(ii), then SIR shall pay to STAR an amount equal to (x) (A) the Go Shop Termination Payment if such termination occurs no later than seven (7) Business Days after the Go Shop Period End Time (or, in the event of timely delivery of a SIR Change Notice, the negotiation period contemplated by Section 7.3(e)(ii)), or (B) the Full Termination Payment if the termination occurs thereafter and (y) up to $2,000,000 as reimbursement for STAR’s Expenses;

(iii)    by STAR pursuant to Section 9.1(d)(ii), then SIR shall pay to STAR an amount equal to (x) (A) the Go Shop Termination Payment if the event giving rise to STAR’s termination right occurred no later than seven (7) Business Days after the Go Shop Period End Time (or, in the event of timely delivery of a SIR Change Notice, the negotiation period contemplated by Section 7.3(e)(ii)), or (B) the Full Termination Payment if the event giving rise to STAR’s termination right occurred thereafter and (y) up to $2,000,000 as reimbursement for STAR’s Expenses; or

(iv)    by SIR pursuant to Section 9.1(c)(i), then STAR shall pay to SIR an amount up to $2,000,000 as reimbursement for SIR’s Expenses.

(c)    Termination Payment. The Parties agree and acknowledge that in no event shall SIR be required to pay the applicable Termination Payment on more than one occasion. Payment of the Termination Payment and reimbursement of Expenses, as applicable, shall be made by wire transfer of same day funds to the account or accounts designated by SIR or STAR, as applicable, (i) within two (2) Business Days after the consummation of any transaction contemplated by an Acquisition Proposal, in the case of any amount payable pursuant to Section 9.3(b)(i); and (ii) as promptly as reasonably practicable after termination (and, in any event, within two (2) Business Days thereof), in the case of any amount payable pursuant to Section 9.3(b)(ii), Section 9.3(b)(iii) or Section 9.3(b)(iv).

(d)    Notwithstanding anything in this Agreement to the contrary, in the event that the Termination Payment becomes payable, then such payment shall be STAR’s and its Affiliates’ sole and exclusive remedy as liquidated damages for any and all losses or damages of any nature against SIR and the SIR Subsidiaries and their respective Representatives in respect of this Agreement, any agreement executed in connection herewith, and the transactions contemplated hereby and thereby, including for any loss or damage suffered as a result of the termination of this Agreement, the failure of the Merger to be consummated or for a breach or failure to perform hereunder (whether intentionally, unintentionally, or otherwise) or otherwise.

(e)    Each of the Parties acknowledges that the agreements contained in this Section 9.3 are an integral part of the transactions contemplated by this Agreement, and that without these agreements, the other Parties would not enter into this Agreement. In the event that

91

SIR shall fail to pay the applicable Termination Payment when due, SIR shall reimburse the STAR for all reasonable costs and expenses actually incurred or accrued by STAR (including reasonable fees and expenses of counsel) in connection with the collection under and enforcement of this Section 9.3. Further, if one Party to this Agreement (the “Termination Payor”) fails to timely pay any amount due to the other Party (the “Termination Payee”) pursuant to Section 9.3(b), and, in order to obtain the payment, the Termination Payee commences a suit which results in a judgment against the Termination Payor for the payment set forth in this Section 9.3, the Termination Payor shall pay to the Termination Payee its reasonable and documented costs and expenses (including reasonable and documented attorneys’ fees) in connection with such suit, together with interest on such amount at a rate per annum equal to the prime rate published in the Wall Street Journal in effect on the date such payment was required to be made through the date of payment.

(f)    If SIR becomes obligated to pay a fee under this Section 9.3, then SIR shall deposit into escrow an amount in cash equal to the applicable Termination Payment with an escrow agent reasonably selected by STAR, after reasonable consultation with SIR, and pursuant to a written escrow agreement (the “Escrow Agreement”) reflecting the terms set forth in this Section 9.3 and otherwise reasonably acceptable to each of the Parties and the escrow agent. The payment or deposit into escrow of the applicable Termination Payment pursuant to this Section 9.3(b) shall be made by SIR promptly after receipt of notice from STAR that the Escrow Agreement has been executed by the parties thereto and once deposited in escrow shall relieve SIR from any further obligation to pay any fee required under this Section 9.3. The Escrow Agreement shall provide that the Termination Payment in escrow or the applicable portion thereof shall be released to STAR on an annual basis based upon the delivery by STAR to the escrow agent of any one (or a combination) of the following:

(i)    a letter from STAR’s independent certified public accountants indicating the maximum amount that can be paid by the escrow agent to STAR without causing STAR to fail to meet the requirements of Sections 856(c)(2) and (3) of the Code for the applicable taxable year of STAR determined as if the payment of such amount did not constitute income described in Sections 856(c)(2)(A) (H) or 856(c)(3)(A) (I) of the Code (such income, “Qualifying REIT Income”), in which case the escrow agent shall release to STAR such maximum amount stated in the accountant’s letter;

(ii)    a letter from STAR’s counsel indicating that STAR received a private letter ruling from the IRS holding that the receipt by STAR of the applicable Termination Payment would either constitute Qualifying REIT 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 to STAR the remainder of the applicable Termination Payment; or

(iii)    a letter from STAR’s counsel indicating that STAR has received a tax opinion from STAR’s outside counsel or accountant, respectively, to the effect that the receipt by STAR of the applicable Termination Payment should either constitute Qualifying REIT Income or should be excluded from gross income within the meaning of Section 856(c)(2) and (3) of the Code, in which case the escrow agent shall release to STAR the remainder of the applicable Termination Payment.

92

The Parties agree to cooperate in good faith to amend this Section 9.3(f) at the reasonable request of STAR in order to (A) maximize the portion of the applicable Termination Payment that may be distributed to STAR hereunder without causing STAR to fail to meet the requirements of Sections 856(c)(2) and (3) of the Code, (B) improve STAR’s chances of securing the favorable private letter ruling from the IRS described in this Section 9.3(f) or (C) assist STAR in obtaining the favorable tax opinion from its outside counsel or accountant described in this Section 9.3(f). The Escrow Agreement shall provide that STAR shall bear all costs and expenses under the Escrow Agreement and that any portion of the applicable Termination Payment held in escrow for ten (10) years shall be released by the escrow agent to SIR. SIR shall not be a party to the Escrow Agreement and shall not bear any liability, cost or expense resulting directly or indirectly from the Escrow Agreement (other than any Taxes imposed on SIR in connection therewith). STAR shall fully indemnify SIR and hold SIR harmless from and against any such liability, cost or expense.

Section 9.4    Amendment. Subject to compliance with applicable Law, this Agreement may be amended by mutual agreement of the Parties by action taken or authorized by the STAR Special Committee and the SIR Special Committee, respectively, at any time before or after receipt of the Stockholder Approval and prior to the Merger Effective Time; provided, that after the Stockholder Approval has been obtained, there shall not be (i) 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 SIR Common Stock, or which by applicable Law requires the further approval of the stockholders of SIR without such further approval of such stockholders, or (ii) 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.

Section 10.3    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 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.

94

Section 10.4    Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original and all of which together shall be deemed one and the same agreement, and shall become effective when one or more counterparts have been signed by each of the Parties and delivered (electronically by email or facsimile) to the other Parties. Signatures to this Agreement transmitted by facsimile transmission, by electronic mail in “portable document form” (“pdf”), or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document, will have the same effect as physical delivery of the paper document bearing the original signature.

Section 10.5    Entire Agreement; No Third-Party Beneficiaries. This Agreement (including the Exhibits, Schedules, the STAR Disclosure Letter and the SIR Disclosure Letter), the Confidentiality Agreements (a) constitute the entire agreement and supersede all prior agreements and understandings, both written and oral, between the Parties with respect to the subject matter of this Agreement and, (b) except for the provisions of Article 3 (which, from and after the Merger Effective Time, shall be for the benefit of holders of shares of STAR Common Stock immediately prior to the Merger Effective Time) and Section 7.7 (which, from and after the Merger Effective Time shall be for the benefit of the Indemnified Parties) are not intended to confer upon any Person other than the Parties hereto any rights or remedies.

Section 10.6    Extension; Waiver.

Any agreement on the part of a Party to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such Party. The failure of any Party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of those rights.

Section 10.7    Governing Law; Venue.

(a)    This Agreement, and all claims or causes of actions (whether at Law, in contract or in tort) that may be based upon, arise out of or related to this Agreement or the negotiation, execution or performance of this Agreement, shall be governed by, and construed in accordance with, the laws of the State of Maryland without giving effect to its conflicts of laws principles (whether 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).

(b)    All disputes arising out of or relating to this Agreement shall be heard and determined exclusively in any Maryland state or federal court.

This Agreement will be binding upon, inure to the benefit of, and be enforceable by, the Parties and their respective successors and assigns.

Section 10.9    Specific Performance.
