The Trust, the Manager and each of the Trust Subsidiaries is duly qualified as a foreign trust, corporation, limited liability company or limited partnership, as the case may be, to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except for such jurisdictions where the failure to so qualify or to be in good standing would not, individually or in the aggregate, result in a material adverse effect on the financial condition, business, properties, operations or prospects, whether or not arising from transactions in the ordinary course of business, of each of the Trust, the Manager and the Trust Subsidiaries, considered as one entity (a "Material Adverse Effect"). Except as set forth in Schedule D, all of the issued and outstanding partnership units or shares of capital stock of each Trust Subsidiary have been duly authorized and validly issued, are fully paid and nonassessable and are owned by the Trust, directly or through the Trust Subsidiaries, free and clear of any security interest, mortgage, pledge, lien, encumbrance or claim.

The description of the Trust's stock option, stock bonus and other stock plans or arrangements, and the options or other rights granted thereunder, set forth in the Disclosure Package and the Prospectus accurately and fairly presents the information required to be shown with respect to such plans, arrangements, options and rights.

On or before the Closing Date, each of the Transaction Agreements will be duly executed and delivered by the relevant CapitalSource Parties and will constitute a valid and binding agreement of such CapitalSource Party enforceable in accordance with its terms, except to the extent that enforcement thereof may be limited by bankruptcy, insolvency, reorganization or other laws affecting enforcement of creditors' rights or by general equitable principles.

collectively, on the one hand, and the Underwriters, on the other hand, will each pay 50% of the cost of any privately chartered airplanes.

SECTION 7. Effectiveness of this Agreement. This Agreement shall not become effective until the later of (i) the execution of this Agreement by the parties hereto and (ii) notification by the Commission to the Trust and the Representatives of the effectiveness of the Registration Statement under the Securities Act.

(a) Indemnification of the Underwriters. Each of the CapitalSource Parties, jointly and severally, agrees to indemnify and hold harmless each Underwriter, its directors, officers, employees and agents, and each person, if any, who controls any Underwriter within the meaning of the Securities Act or the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which such Underwriter, director, officer, employee, agent or controlling person may become subject, insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based (i) upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any amendment thereto, including any information deemed to be a part thereof pursuant to Rule 430A, Rule 430B or Rule 430C under the Securities Act, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading; or (ii) upon any untrue statement or alleged untrue statement of a material fact contained in any Issuer Free Writing Prospectus, any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) or any prospectus wrapper or any "road show" (as defined in Rule 433 under the Securities Act) not constituting an Issuer Free Writing Prospectus (a "Non-IFWP Road Show"), or the omission or alleged omission therefrom of a material fact, in each case, necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, and to reimburse each Underwriter, its officers, directors, employees, agents and each such controlling person for any and all expenses (including the fees and disbursements of counsel chosen by the Representatives) as such expenses are reasonably incurred by such Underwriter, or its officers, directors, employees, agents or such controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing indemnity agreement shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission based upon and in conformity with written information furnished to the Trust by any Underwriter through the Representatives expressly for use in the Registration Statement, any Issuer Free Writing Prospectus, any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) or any Non-IFWP Road Show, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 8(b) hereof. The indemnity agreement set forth in this Section 8(a) shall be in addition to any liabilities that the CapitalSource Parties may otherwise have.

(b) Indemnification of the CapitalSource Parties and their Trustees, Directors and/or Officers. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the CapitalSource Parties, each of their respective trustees, directors and officers (or persons holding similar offices in the case of CapitalSource Parties that are not corporations) and each person, if any, who controls the CapitalSource Parties within the meaning of the Securities Act or the Exchange Act, against any loss,

claim, damage, liability or expense, as incurred, to which the CapitalSource Parties or any their respective trustees, directors, officers, or controlling persons may become subject, insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any Issuer Free Writing Prospectus, any preliminary prospectus, or the Prospectus (or any amendment or supplement thereto) or any Non-IFWP Road Show, or arises out of or is based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, and only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, any Issuer Free Writing Prospectus, any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) or any Non-IFWP Road Show, in reliance upon and in conformity with written information furnished to the Trust by the Representatives expressly for use therein; and to reimburse the CapitalSource Parties or any of their respective trustees, directors, officers, or controlling persons for any legal and other expense reasonably incurred by the CapitalSource Parties or any of their respective trustees, directors, officers, or controlling persons in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. Each of the CapitalSource Parties hereby acknowledge that the only information that the Underwriters have furnished to the Trust expressly for use in the Registration Statement, any Issuer Free Writing Prospectus, any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) or any Non-IFWP Road Show are the statements set forth in the third paragraph (relating to the concessions and reallowance figures only) and the fourteenth paragraph under the caption "Underwriting" in the Prospectus and the statements set forth under the caption "Underwriting-Stabilization" in the Prospectus. The indemnity agreement set forth in this Section 8(b) shall be in addition to any liabilities that each Underwriter may otherwise have.

(c) Notifications and Other Indemnification Procedures. Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof, but the failure to so notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party's election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the

indemnified party shall have employed separate counsel in accordance with the proviso to the preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (other than local counsel), reasonably approved by the indemnifying party (or by the Representatives in the case of Section 8(b)), representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party.

(d) Settlements. The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, which shall not be withheld unreasonably, but if settled with such consent or if there is a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by Section 8(c) hereof, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (x) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (y) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

SECTION 9. Contribution. If the indemnification provided for in Section 8 is for any reason unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the CapitalSource Parties, on the one hand, and the Underwriters, on the other hand, from the offering of the Shares pursuant to this Agreement or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the CapitalSource Parties, on the one hand, and the Underwriters, on the other hand, in connection with the untrue statements or omissions or alleged untrue statements or alleged omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the CapitalSource Parties, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Shares pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Shares pursuant to this Agreement (before deducting expenses) received by the CapitalSource Parties, and the total underwriting discount received by the Underwriters, in each case as set forth on the front cover page of the Prospectus bear to the aggregate initial public offering price of the Shares as set forth on such cover. The relative fault of the CapitalSource Parties, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the CapitalSource Parties, on the one hand, or the Underwriters, on the other hand, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 8(c), any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim.

The CapitalSource Parties and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in this Section 9.

Notwithstanding the provisions of this Section 9, no Underwriter shall be required to contribute any amount in excess of the underwriting commissions received by such Underwriter in connection with the Shares underwritten by it and distributed to the public. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations to contribute pursuant to this Section 9 are several, and not joint, in proportion to their respective underwriting commitments as set forth opposite their names in Schedule A. For purposes of this Section 9, each director, officer, employee and agent of an Underwriter and each person, if any, who controls an Underwriter within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as such Underwriter; each trustee, director and officer (or persons holding similar offices in the case of CapitalSource Parties that are not corporations) and each person, if any, who controls the CapitalSource Parties within the meaning of the Securities Act or the Exchange Act, shall have the same rights to contribution as the CapitalSource Parties.

SECTION 10. Default of One or More of the Several Underwriters. If, on the Closing Date or a Subsequent Closing Date, as the case may be, any one or more of the several Underwriters shall fail or refuse to purchase Shares that it or they have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase does not exceed 10% of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated, severally, in the proportions that the number of Firm Shares set forth opposite their respective names on Schedule A bears to the aggregate number of Firm Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as may be specified by the Representatives with the consent of the non-defaulting Underwriters, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date. If, on the Closing Date or a Subsequent Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares and the aggregate number of Shares with respect to which such default occurs exceeds 10% of the aggregate number of Shares to be purchased on such date, and arrangements satisfactory to the Representatives and the Trust for the purchase of such Shares are not made within 48 hours after such default, this Agreement shall terminate without liability of any party to any other party except that the provisions of Section 4, Section 6, Section 8 and Section 9 shall at all times be effective and shall survive such termination. In any such case either the Representatives or the Trust shall have the right to postpone the Closing Date or a Subsequent Closing Date, as the case may be, but in no event for longer than seven days in order that the required changes, if any, to the Registration Statement and the Prospectus or any other documents or arrangements may be effected.

As used in this Agreement, the term "Underwriter" shall be deemed to include any person substituted for a defaulting Underwriter under this Section 10. Any action taken under this Section 10 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

SECTION 11. Termination of this Agreement. Prior to the Closing Date and, with respect to the Optional Shares, any Subsequent Closing Date, this Agreement may be terminated by the Representatives by notice given to the Trust and the Selling Shareholder if at any time (i) trading or quotation in any of the Trust's securities shall have been suspended or limited by the Commission or by the NYSE, or trading in securities generally on the NYSE shall have been suspended or limited, or minimum or maximum prices shall have been generally established by the Commission or FINRA or on such stock exchange; (ii) a general banking moratorium shall have been declared by federal or New York authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States has occurred; or (iii) there shall have occurred any outbreak or escalation of national or international hostilities or declaration of a national emergency or war by the United States or any crisis or calamity, or any change in the United States or international financial markets, or any substantial change or development involving a prospective substantial change in United States' or international political, financial or economic conditions, as in the judgment of the Representatives is material and adverse and makes it impracticable or inadvisable to market the Shares in the manner and on the terms described in the Prospectus or to enforce contracts for the sale of securities. Any termination pursuant to this Section 11 shall be without liability on the part of (a) the CapitalSource Parties to any Underwriter, except that the CapitalSource Parties shall be obligated to reimburse the expenses of the Representatives and the Underwriters pursuant to Sections 4 and 6 hereof except 50% of the cost of privately chartered airplanes which is to be borne by the Underwriters pursuant to Section 4(ix) hereof or (b) any Underwriter to the CapitalSource Parties.

SECTION 12. No Advisory or Fiduciary Responsibility. Each of the CapitalSource Parties acknowledges and agrees that: (i) the purchase and sale of the Shares pursuant to this Agreement, including the determination of the public offering price of the Shares and any related discounts and commissions, is an arm's-length commercial transaction between the CapitalSource Parties, on the one hand, and the several Underwriters, on the other hand, and the CapitalSource Parties are capable of evaluating and understanding and understand and accept the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with each transaction contemplated hereby and the process leading to such transaction each Underwriter is and has been acting solely as a principal and is not the financial advisor, agent or fiduciary of any of the CapitalSource Parties or its affiliates, stockholders, creditors or employees or any other party; (iii) no Underwriter has assumed or will assume an advisory, agency or fiduciary responsibility in favor of the CapitalSource Parties with respect to any of the transactions contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the CapitalSource Parties on other matters) and no Underwriter has any obligation to the CapitalSource Parties with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement; (iv) the several Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the CapitalSource Parties and that the several Underwriters have no obligation to disclose any of such interests by virtue of any advisory, agency or fiduciary relationship; and (v) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the CapitalSource Parties have consulted their own legal, accounting, regulatory and tax advisors to the extent they deemed appropriate.

This Agreement supersedes all prior agreements and understandings (whether written or oral) between the CapitalSource Parties and the several Underwriters, or any of them, with respect to the subject matter hereof. The CapitalSource Parties hereby waive and release, to the fullest extent permitted by law, any claims that the CapitalSource Parties may have against the several Underwriters with respect to any breach or alleged breach of agency or fiduciary duty in connection with the matters contemplated by this Agreement.

SECTION 13. Research Analyst Independence. The Trust and the Selling Shareholder acknowledge that the Underwriters' research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters' research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Trust and/or the offering that differ from the views of their respective investment banking divisions. The Trust and the Selling Shareholder hereby waive and release, to the fullest extent permitted by law, any claims that the Trust or the Selling Shareholder may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Trust or the Selling Shareholder by such Underwriters' investment banking divisions. The Trust and the Selling Shareholder acknowledge that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement.

SECTION 14. Representations and Indemnities to Survive Delivery. The respective indemnities, agreements, representations, warranties and other statements of the CapitalSource Parties, of their officers and of the several Underwriters set forth in or made pursuant to this Agreement (i) will remain operative and in full force and effect, regardless of any (A) investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the officers or employees of any Underwriter, or any person controlling the Underwriter, the CapitalSource Parties, the officers or employees of the CapitalSource Parties, or any person controlling the CapitalSource Parties, as the case may be or (B) acceptance of the Shares and payment for them hereunder and (ii) will survive delivery of and payment for the Shares sold hereunder and any termination of this Agreement.

SECTION 15. Notices. All communications hereunder shall be in writing and shall be mailed, hand delivered or telecopied and confirmed to the parties hereto as follows:

Any party hereto may change the address for receipt of communications by giving written notice to the others.

SECTION 16. Successors and Assigns. This Agreement will inure to the benefit of and be binding upon the parties hereto, including any substitute Underwriters pursuant to Section 10 hereof, and to the benefit of (i) each of the CapitalSource Parties, the trustees, directors and officers (or persons holding similar offices in the case of CapitalSource Parties that are not corporations) and any person who controls the CapitalSource Parties within the meaning of the Securities Act or the Exchange Act, (ii) the Underwriters, the officers, directors, employees and agents of the Underwriters, and each person, if any, who controls any Underwriter within the meaning of the Securities Act or the Exchange Act , and (iii) the respective successors and assigns of any of the above, all as and to the extent provided in this Agreement, and no other person shall acquire or have any right under or by virtue of this Agreement. The term "successors and assigns" shall not include a purchaser of any of the Shares from any of the several Underwriters merely because of such purchase.

SECTION 17. Partial Unenforceability. The invalidity or unenforceability of any Section, paragraph or provision of this Agreement shall not affect the validity or enforceability of any other Section, paragraph or provision hereof.

The undersigned is or may become an owner of record or beneficially of certain common shares of beneficial interest of the Trust ("Common Shares") or securities convertible into or exchangeable or exercisable for Common Shares.

The undersigned recognizes that the Offering will be of benefit to the undersigned and will benefit the Trust. The undersigned acknowledges that you and the other underwriters are relying on the representations and agreements of the undersigned contained in this letter in carrying out the Offering and in entering into an underwriting agreement with the Trust with respect to the Offering (the "Underwriting Agreement").

In consideration of the foregoing, the undersigned hereby agrees that the undersigned will not, (and will cause any spouse or immediate family member of the spouse or the undersigned living in the undersigned's household not to), without the prior written consent of Banc of America Securities LLC, Citigroup Global Markets Inc. and Deutsche Bank Securities Inc.

The foregoing sentence shall not apply to (i) the transfer of any or all of the Common Shares owned by the

undersigned, either during his or her lifetime or on death, by gift, will or intestate succession to the immediate family of the undersigned or to a trust the beneficiaries of which are exclusively the undersigned and/or a member or members of his or her immediate family (for purposes of this agreement, "immediate family" shall mean any relationship by blood, marriage or adoption, not more remote than first cousin); (ii) any bona fide gifts to any charitable organization; (iii) the transfer or distribution of any or all of the Common Shares owned by the undersigned to any other person or entity, for as long as such other person or entity is an "affiliate" of the undersigned, as defined in Rule 405 under the Securities Act of 1933, as amended (the "Act"); or (iv) the pledge of any or all of the Common Shares or other securities convertible into or exchangeable or exercisable for Common Shares or derivatives of Common Shares owned by the undersigned on the date of the Underwriting Agreement pursuant to a pledge of securities in connection with a bona fide loan transaction; provided, however, that in any such case it shall be a pre-condition to such transfer, distribution or pledge that (a) the transferee, donee or pledgee thereof agree in writing to be bound by the restriction set forth herein, (b) no filing by any party (transferor, transferee, donor, donee, pledgor or pledgee) under the Exchange Act shall be required or shall be voluntarily made in connection with such transfer, distribution or pledge (other than a filing on a Form 5, Schedule 13D or Schedule 13G (or 13D A or 13G A) made after the expiration of the Lock-Up Period), except in case of a transfer, distribution or pledge pursuant to subsection (iii) and (iv) above made after the earlier of the 30th day following the public offering date set forth on the final prospectus or January 1, 2009, (c) each party (transferor, transferee, donor, donee, pledgor or pledgee) shall not be required by law (including without limitation the disclosure requirements of the Act and the Exchange Act) to make, and shall agree to not voluntarily make, any public announcement of the transfer, distribution or pledge, except in case of a transfer, distribution or pledge pursuant to subsection (iii) and (iv) above made after the earlier of the 30th day following the public offering date set forth on the final prospectus or January 1, 2009, and (d) the undersigned notifies the Representatives at least three business days prior to the proposed transfer, distribution or pledge.

Notwithstanding the foregoing, it is expressly agreed and acknowledged that, during the Lock-Up Period or any extension period provided herein, the undersigned may make any demand for or exercise any right with respect to, the registration of any Common Shares or any security convertible into or exercisable or exchangeable for Common Shares provided that such demand specifies that the filing of a registration statement on an appropriate form under the Act with respect to such demand shall not be made until the first business day following the expiration of the Lock-Up Period and any extension period and provided further that no filing or public announcement by any party shall be required by law or voluntarily made in connection with such demand until the first business day following the expiration of the Lock-Up Period and any extension period.

If (i) the Trust issues an earnings release or material news, or a material event relating to the Trust occurs, during the last 17 days of the Lock-Up Period, or (ii) prior to the expiration of the Lock-Up Period, the Trust announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period, the restrictions imposed by this agreement shall continue to apply until the expiration of the 18-day period beginning on the date of the issuance of the earnings release or the occurrence of the material news or material event, unless the Representatives waive, in writing, such extension. The undersigned hereby agrees that, prior to engaging in any transaction or taking any other action that is subject to the terms of this agreement during the period from the date of this agreement to and including the 34th day following the expiration of the initial Lock-Up Period, it will give notice thereof to the Trust and will not consummate such transaction or take any such action unless it has received confirmation from the Trust that the Lock-Up Period (as such may have been extended pursuant to the this paragraph) has expired. The undersigned also agrees and consents to the entry of stop transfer instructions with the Trust's transfer agent and registrar against the transfer of Common Shares or securities convertible into or exchangeable or exercisable for Common Shares held by the undersigned except in compliance with the foregoing restrictions.

This agreement is irrevocable and will be binding on the undersigned and the respective successors, heirs, personal representatives, and assigns of the undersigned.
