2.1. Shelf Registration.

2.1.1 Shelf Registration Requirement. The Trust shall prepare and file, at its own expense, not later than the 30th day prior to the expiration of the lockup period described in the Share Purchase Agreement, a “shelf” registration statement with respect to the resale of all Registrable Securities (“Resale Shelf Registration”) by the Holders on an appropriate form for an offering to be made on a delayed or continuous basis pursuant to Rule 415 under the Securities Act or any successor thereof (the “Resale Shelf Registration Statement”) and permitting registration of such Registrable Securities for resale by such Holders in accordance with the methods of distribution elected by the Holders pursuant to the questionnaire referred to in Section 2.1.3 below and set forth in the Resale Shelf Registration Statement. The Trust may include in such registration additional securities of the class of Registrable Securities to be registered thereunder, including securities to be sold for the Trust’s own account or the account of Persons who are not Holders of Registrable Securities. The Trust shall use its reasonable best efforts to cause the Resale Shelf Registration Statement to be declared effective by the Commission within 150 days after the filing thereof (if it is not an automatic shelf registration statement), and, subject to Section 2.2, to keep such Resale Shelf Registration Statement continuously effective for a period ending when all Private Placement Common Shares covered by the Resale Shelf Registration Statement are no longer Registrable Securities, including, if necessary, by filing with the SEC a post-effective amendment or a supplement to the Resale Registration Statement or the related Prospectus or any document incorporated therein by reference or by filing any other required document or otherwise supplementing or amending the Resale Registration Statement, if required by the rules, regulations or instructions applicable to the registration form used by the Trust for such Resale Registration Statement or by the Securities Act, the Exchange Act, any state securities or blue sky laws or any rules and regulations thereunder.

2.1.2 Underwritten Offering; Reduction of Offering. Each Holder of the Registrable Securities shall have the right to request that an underwritten offering be effected off the Resale Shelf Registration at any time, subject to Section 2.2. All Holders proposing to participate in such underwriting shall (i) enter into an underwriting agreement in customary form with the underwriter(s) selected for such underwriting by a Majority-in-Interest of the Registrable Securities included in such offering, which underwriter(s) shall be reasonably

acceptable to the Trust and (ii) complete and execute all questionnaires, powers-of-attorney, indemnities, opinions and other documents required under the terms of such underwriting agreement. Notwithstanding the foregoing, in no event shall the Trust be obligated to effect more than two (2) underwritten offerings hereunder in any single six-month period. If the managing underwriter(s) for an underwritten offering advises the Trust and the Holders in writing that the dollar amount or number of Registrable Securities which the Holders desire to sell, taken together with all other Common Shares or other securities which the Trust desires to sell and the Common Shares or other securities, if any, as to which registration has been requested pursuant to written contractual piggy-back registration rights held by other shareholders of the Trust who desire to sell or otherwise, exceeds the maximum dollar amount or maximum number of securities that can be sold in such offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such offering (such maximum dollar amount or maximum number of securities, as applicable, the “Maximum Threshold”), then the Trust shall include in such registration: (a) first, the Registrable Securities (pro rata in accordance with the number of Registrable Securities which such Holders have requested be included in such underwritten offering, regardless of the number of Registrable Securities or other securities held by each such Person (such proportion is referred to herein as “Pro Rata Adjusted”)) that can be sold without exceeding the Maximum Threshold; (b) second, to the extent that the Maximum Threshold has not been reached under the foregoing clause (a), the Common Shares or other securities that the Trust desires to sell that can be sold without exceeding the Maximum Threshold; (c) third, to the extent that the Maximum Threshold has not been reached under the foregoing clauses (a) and (b), the Common Shares or other securities for the account of other Persons that the Trust is obligated to register pursuant to written contractual arrangements with such Persons and that can be sold without exceeding the Maximum Threshold; and (d) fourth, to the extent that the Maximum Threshold has not been reached under the foregoing clauses (a), (b) and (c), the Common Shares that other shareholders desire to sell that can be sold without exceeding the Maximum Threshold to the extent that the Trust, in its sole discretion, wishes to permit such sales pursuant to this clause (d).

A request for an underwritten offering may be withdrawn by a Majority-in-Interest of the Registrable Shares included in such offering prior to the consummation thereof, and, in such event, such withdrawal shall not be treated as a request for an underwritten offering which shall have been effected pursuant to the immediately preceding paragraph.

2.1.3 Inclusion in Resale Shelf Registration. The Trust shall give written notice to all Holders at least 20 Business Days prior to the anticipated filing date of the Resale Shelf Registration Statement, which notice shall include a questionnaire seeking information from the Holders deemed necessary or advisable by the Trust or its counsel in order to file the Resale Shelf Registration Statement. At the time the Resale Shelf Registration Statement is declared effective (or becomes effective, if the Registration Statement is an automatic shelf registration statement), each Holder that has delivered to the Trust a duly completed and executed questionnaire on or prior to the date which is ten Business Days prior to such time of effectiveness shall be named as a selling shareholder in the Resale Shelf Registration Statement and the related Prospectus in such a manner as to permit such Holder to deliver such Prospectus to purchasers of Registrable Securities in accordance with applicable law. Subject to the terms and conditions hereof, after effectiveness of the Resale Shelf Registration Statement, the Trust shall file a supplement to such Prospectus or amendment to the Resale Shelf Registration

Statement upon request of any Holder as necessary to name as selling shareholders therein any Holders that provide to the Trust duly completed and executed questionnaires and shall use commercially reasonable efforts to cause any post-effective amendment to such Resale Shelf Registration Statement filed for such purpose to be declared effective (if it is not an automatic shelf registration statement) by the Commission as promptly as reasonably practicable after the filing thereof.

2.1.4 Continued Effectiveness. The Trust shall prepare and file such additional Registration Statements as necessary every three years (or such other period of time as may be required to maintain continuously effective shelf registration statements) and use its reasonable best efforts to cause such Registration Statements to be declared effective by the Commission (if it is not an automatic shelf registration statement) so that a shelf registration statement remains continuously effective, subject to Section 2.2, with respect to resales of Registrable Securities as and for the periods required under Section 2.1.1, each such subsequent Registration Statement to constitute a Resale Shelf Registration Statement hereunder.

2.2. Suspension of Use of Registration Statement.

2.2.1 Upon prior written notice to the Holders, the Trust may suspend the use of a Resale Shelf Registration Statement pursuant to Section 2.1 on up to two occasions during any period of twelve consecutive months for a reasonable time specified in the notice but not exceeding 90 days in the aggregate during any such twelve month period (which period may not be extended or renewed), if (i) the Board determines in good faith that permitting sales under the Registration Statement would materially and adversely affect an offering of securities of the Trust; (ii) a Piggy-Back Registration (defined below) in which Holders were able to participate was completed within the prior 90 days; or (iii) the Trust is in possession of material non-public information and the Board determines in good faith that the disclosure of such information during the period specified in such notice would not be in the best interests of the Trust.

2.2.2 If all reports required to be filed by the Trust pursuant to the Exchange Act have not been filed by the required date taking into account any permissible extension, upon written notice thereof by the Trust to the Holders, the rights of the Holders to offer, sell or distribute any Registrable Securities pursuant to any Registration Statement or to require the Trust to take action with respect to the registration or sale of any Registrable Securities pursuant to any Registration Statement shall be suspended until the date on which the Trust has filed such reports, and the Trust shall notify the Holders in writing as promptly as practicable when such suspension is no longer required.

2.3. Piggy-Back Registration.

2.3.1 Piggy-Back Rights. At any time after [·], 2012 (the third anniversary of the closing of the transactions under the Share Purchase Agreement), if the Trust proposes to file a Registration Statement under the Securities Act with respect to an offering of equity securities by the Trust for its own account or for shareholders of the Trust for their account and the registration form to be used may be used for any registration of Registrable Securities or if the Trust proposes to conduct an offering at any time after [·], 2012 using any such Registration Statement filed prior to [·], 2012 for its own account or for shareholders of the Trust, then the

Trust shall (a) give written notice of such proposed filing and/or offering to the Holders of Registrable Securities as soon as practicable but in no event less than ten Business Days before the anticipated filing date, which notice shall describe the amount and type of securities to be included in such offering, the intended method(s) of distribution, and the name of the proposed managing underwriter(s), if any, of the offering, and (b) offer to the Holders of Registrable Securities in such notice the opportunity to register the sale of such number of Registrable Securities as such Holders may request in writing within five Business Days following receipt of such notice (a “Piggy-Back Registration”). If at any time after giving written notice of its intention to register any securities and prior to the effective date of the Registration Statement filed in connection with such registration, the Trust shall determine for any reason not to register or to delay registration of such securities, the Trust may, at its election, give written notice of such determination to each Holder of Registrable Securities and, (x) in the case of a determination not to register, shall be relieved of its obligation to register any Registrable Securities in connection with such registration, and (y) in the case of a determination to delay registering, shall be permitted to delay registering any Registrable Securities for the same period as the delay in registering such other securities. The Trust shall cause such Registrable Securities to be included in such registration and shall use its reasonable best efforts to cause the managing underwriter(s) of a proposed underwritten offering to permit the Registrable Securities requested to be included in a Piggy-Back Registration on the same terms and conditions as any similar securities of the Trust and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. All Holders of Registrable Securities proposing to distribute their securities through a Piggy-Back Registration that involves an underwriter(s) shall enter into an underwriting agreement in reasonable and customary form with the underwriter(s) selected for such Piggy-Back Registration and (ii) complete and execute all questionnaires, powers-of-attorney, indemnities, opinions and other documents reasonably required under the terms of such underwriting agreement. No registration effected under this Section 2.3 shall relieve the Trust of its obligations to effect a Resale Shelf Registration required by Section 2.1.

2.3.2 Reduction of Offering. If the managing underwriter(s) for a Piggy-Back Registration that is to be an underwritten offering advises the Trust and the Holders of Registrable Securities that in their opinion the dollar amount or number of Common Shares or other securities which the Trust desires to sell, taken together with Common Shares or other securities, if any, as to which registration has been demanded pursuant to written contractual arrangements with third parties, the Registrable Securities as to which registration has been requested under this Section 2.3, and the Common Shares or other securities, if any, as to which registration has been requested pursuant to the written contractual piggy-back registration rights of other shareholders of the Trust, exceeds the Maximum Threshold, then the Trust shall include in any such registration:

(a) If the registration is undertaken for the Trust’s account: (i) first, the Common Shares or other securities that the Trust desires to sell that can be sold without exceeding the Maximum Threshold; (ii) second, to the extent that the Maximum Threshold has not been reached under the foregoing clause (i), the Common Shares or other securities, if any, comprised of Registrable Securities as to which registration has been requested pursuant to the terms hereof, Pro Rata Adjusted, that can be sold without exceeding the Maximum Threshold; and (iii) third, to the extent that the Maximum Threshold has not been reached under the

foregoing clauses (i) and (ii), the Common Shares or other securities for the account of other Persons that the Trust is obligated to register pursuant to written contractual piggy-back registration rights with such Persons and that can be sold without exceeding the Maximum Threshold; and

(b) If the registration is a “demand” registration undertaken at the demand of one or more parties other than the Trust, (i) first, the Common Shares or other securities for the account of such demanding parties that can be sold without exceeding the Maximum Threshold; (ii) second, to the extent that the Maximum Threshold has not been reached under the foregoing clause (i), the Common Shares or other securities that the Trust desires to sell that can be sold without exceeding the Maximum Threshold; (iii) third, to the extent that the Maximum Threshold has not been reached under the foregoing clauses (i) and (ii), the Common Shares or other securities, if any, comprised of Registrable Securities as to which registration has been requested pursuant to the terms hereof, Pro Rata Adjusted, that can be sold without exceeding the Maximum Threshold; and (iv) fourth, to the extent that the Maximum Threshold has not been reached under the foregoing clauses (i), (ii) and (iii), the Common Shares or other securities, if any, for the account of other Persons that the Trust is obligated to register pursuant to written contractual piggy-back registration rights with such Persons that can be sold without exceeding the Maximum Threshold.

2.3.3 Withdrawal. Any Holder of Registrable Securities may elect to withdraw such Holder’s request for inclusion of Registrable Securities in any Piggy-Back Registration by giving written notice to the Trust of such request to withdraw prior to the effectiveness of the Registration Statement or filing of a Prospectus naming such Holder as a selling shareholder, as applicable. The Trust (whether on its own determination or as the result of a withdrawal by Persons making a demand pursuant to written contractual obligations) may withdraw a Registration Statement at any time prior to the effectiveness of the Registration Statement without thereby incurring any liability to the Holders of Registrable Securities. Notwithstanding any such withdrawal, the Trust shall pay all expenses incurred by the Holders of Registrable Securities in connection with such Piggy-Back Registration as provided in Section 4.3.

3. Restrictions on Public Sale by the Trust.

If requested by the lead underwriter(s) in any underwritten offering, the Trust agrees not to effect any public sale or distribution (other than, in the case of the Trust, in connection with (a) any merger, acquisition or similar transaction that involves the public offering of securities, (b) public sales or distributions solely by and for the account of the Trust of securities issued pursuant to any employee benefit or similar plan, including employee stock and stock option plans or, (c) any dividend reinvestment plan), of any securities during the period commencing on the date the Trust receives a request for an underwritten offering from any Holder and continuing until 90 days after the commencement of an underwritten offering (or for such shorter period as the lead underwriter(s) shall request) unless earlier terminated by the lead underwriter(s) in such underwritten offering.

Upon receipt of any notice from the Trust of the happening of any event of the kind described in Section 4.1.4(d), each Holder of Registrable Securities included in any registration shall immediately discontinue disposition of such Registrable Securities pursuant to the Registration Statement covering such Registrable Securities until such Holder receives the supplemented or amended Prospectus contemplated by Section 4.1.4(d) and, if so directed by the Trust, each such Holder will destroy all copies, other than permanent file copies then in such Holder’s possession, of the most recent Prospectus covering such Registrable Securities at the time of receipt of such notice.

4.3. Registration Expenses. The Trust shall pay the following costs and expenses incurred in connection with (a) any Resale Shelf Registration pursuant to Section 2.1 and (b) any

Piggy-Back Registration pursuant to Section 2.3, and all expenses incurred in performing or complying with its other obligations under this Agreement, whether or not the Registration Statement becomes effective, including, without limitation: (i) all registration and filing fees; (ii) fees and expenses of compliance with securities or “blue sky” laws (including fees and disbursements of counsel in connection with blue sky qualifications of the Registrable Securities); (iii) printing expenses; (iv) the fees and expenses incurred in connection with the listing of the Registrable Securities as required by Section 4.1.11; (v) Financial Industry Regulatory Authority, Inc. fees; (vi) fees and disbursements of counsel for the Trust and fees and expenses for independent public accountants retained by the Trust (including the expenses or costs associated with the delivery of any opinions or comfort letters requested pursuant to Section 4.1.9); (vii) the fees and expenses of any special experts retained by the Trust in connection with such Registration; and (viii) the reasonable fees and expenses of one legal counsel selected by the holders of a Majority-in-Interest of the Registrable Securities included in such Registration. The Trust shall have no obligation to pay any other costs or expenses in the course of the transaction contemplated hereby, including underwriting discounts or selling commissions attributable to the Registrable Securities being sold by the Holders thereof, which underwriting discounts or selling commissions shall be borne by such Holders.

The Trust shall have the right to exclude any Holder that does not comply with the preceding sentence from the applicable Registration.

The obligation of the Trust to bear the expenses described in this Section 4.3 shall apply irrespective of whether a registration becomes effective, is withdrawn or suspended, is converted to another form of registration and irrespective of when any of the foregoing shall occur.

4.4. Information. In connection with the filing of any Registration Statement covering Registrable Securities, the Holders of Registrable Securities shall provide such information as may reasonably be requested by the Trust in connection with the preparation of any Registration Statement in order to effect the registration of any Registrable Securities under the Securities Act pursuant to Section 2 and in connection with the Trust’s obligation to comply with federal and applicable state securities laws. If a Holder fails to provide such information after reasonably requested, the Trust may omit such Holder’s Registrable Securities from such Registration Statement.

5. Indemnification and Contribution.

5.1. Indemnification by the Trust. The Trust agrees to indemnify and hold harmless to the fullest extent permitted by law each Holder of Registrable Securities, and each of their respective officers, employees, Affiliates, trustees, directors, partners, members, attorneys and agents, and each Person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act) such Holder of Registrable Securities from and against any expenses, losses, judgments, claims, damages or liabilities (“Losses”) arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement under which the sale of such Registrable Securities was registered under the Securities Act, Prospectus (including any preliminary Prospectus), or any amendment thereof or supplement thereto, or arising out of or based upon any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein,

in the case of the Prospectus in the light of the circumstances under which they were made, not misleading; provided, however, that the Trust will not be liable in any such case to any Holder to the extent that any such Loss arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in such Registration Statement, Prospectus, or any such amendment thereof or supplement thereto, in reliance upon and in conformity with information furnished to the Trust, in writing, by such Holder expressly for use therein.

5.2. Indemnification by Holders of Registrable Securities. In connection with any Registration Statement in which a Holder is participating and as a condition to such participation, each Holder of Registrable Securities agrees, severally and not jointly, to indemnify and hold harmless to the fullest extent permitted by law the Trust, and each of its officers, employees, Affiliates, trustees and agents, and each Person who controls the Trust within the meaning of the Securities Act and each underwriter (if any), and each Person, if any, who controls such underwriter within the meaning of the Securities Act, against any Losses, insofar as such Losses (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement under which the sale of such Registrable Securities was registered under the Securities Act, Prospectus (including any preliminary Prospectus), or any amendment thereof or supplement thereto, or arise out of or are based upon any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statement therein, in the case of the Prospectus in the light of the circumstances under which they were made, not misleading, if the statement or omission was made in reliance upon and in conformity with information furnished in writing to the Trust by such Holder expressly for use therein. Each Holder’s indemnification obligations hereunder shall be several and not joint and shall be limited to the amount of gross proceeds actually received by such Holder from sales of Registrable Securities giving rise to such obligations.

Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Trust or any Indemnified Party and shall survive the transfer of such securities by any Holder.

5.3. Conduct of Indemnification Proceedings. Promptly after receipt by any Person of any notice of any Loss or any action in respect of which indemnity may be sought pursuant to Section 5.1 or 5.2, such Person (the “Indemnified Party”) shall, if a claim in respect thereof is to be made against any other Person for indemnification hereunder, notify such other Person (the “Indemnifying Party”) in writing of the Loss or action; provided, however, that the failure by the Indemnified Party to notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability which the Indemnifying Party may have to such Indemnified Party hereunder, except and solely to the extent the Indemnifying Party is actually and materially prejudiced by such failure. If the Indemnified Party is seeking indemnification with respect to any claim or action brought against the Indemnified Party, then the Indemnifying Party shall be entitled to participate in such claim or action, and, to the extent that it wishes, jointly with all other Indemnifying Parties, to assume control of the defense thereof with counsel reasonably satisfactory to the Indemnified Party. After notice from the Indemnifying Party to the Indemnified Party of its election to assume control of the defense of such claim or action, the Indemnifying Party shall not be liable to the Indemnified Party for any legal or other expenses subsequently incurred by the Indemnified Party in connection with the defense thereof other than

reasonable costs of investigation; provided, however, that in any action in which both the Indemnified Party and the Indemnifying Party are named as defendants or if such Indemnified Party or parties determines in good faith that a conflict of interest exists and that therefore it is advisable for such Indemnified Party or parties to be represented by separate counsel or that, upon advice of counsel, there may be legal defenses available to it or them which are different from or in addition to those available to the Indemnifying Party, then the Indemnifying Party or parties shall not be entitled to assume such defense and the Indemnified Party or parties shall be entitled to separate counsel at the Indemnifying Party’s or parties’ expense. If an Indemnifying Party or parties is not so entitled to assume the defense of such action or does not assume such defense, after having received the notice referred to in the first sentence of this paragraph, the Indemnifying Party or parties will pay the reasonable fees and expenses of counsel for the Indemnified Party or parties (limited in each jurisdiction to one counsel for all underwriters and another counsel for all other Indemnified Parties under this Agreement). The Indemnified Party shall have the right to employ separate counsel (but no more than one such separate counsel, which firm shall be designated in writing by those Indemnified Parties who sold a majority of the Registrable Shares sold by all such Indemnified Parties) to represent the Indemnified Party or parties and their respective controlling Persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Indemnified Party or parties against the Indemnifying Party or parties, with the fees and expenses of such counsel to be paid by such Indemnifying Party. No Indemnifying Party shall, without the prior written consent of any Indemnified Party or parties, consent to entry of judgment or effect any settlement of any claim or pending or threatened proceeding in respect of which the Indemnified Party or parties are or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such judgment or settlement includes an unconditional release of such Indemnified Party from all liability arising out of such claim or proceeding and does not include any statement of admission of fault, culpability or failure to act by or on behalf of such Indemnified Party.

5.4. Contribution.

5.4.1 If the indemnification provided for in this Section 5 is unavailable to any Indemnified Party or insufficient to hold it harmless in respect of any Loss referred to herein, then each such Indemnifying Party, in lieu of indemnifying such Indemnified Party or parties, shall contribute to the amount paid or payable by such Indemnified Party or parties as a result of such Loss in such proportion as is appropriate to reflect the relative fault of the Indemnified Parties and the Indemnifying Parties in connection with the actions or omissions which resulted in such Loss, as well as any other relevant equitable considerations. The relative fault of any Indemnified Party and any Indemnifying Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by such Indemnified Party or such Indemnifying Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

5.4.2 The parties agree that it would not be just and equitable if contribution pursuant to this Section 5.4 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding Section 5.4.1.

5.4.3 The amount paid or payable by an Indemnifying Party as a result of any Loss shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 5.4, no Holder of Registrable Securities shall be required to contribute any amount in excess of the dollar amount by which the gross proceeds actually received by such Holder from the sale of Registrable Securities exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. 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.

5.4.4 The indemnity and contribution agreements contained in this Section 5 are in addition to any liability which the Indemnifying Parties may otherwise have to the Indemnified Parties hereunder, under applicable law or at equity.

6. Underwriting and Distribution.

6.1. Rule 144. At such times as the Trust is obligated to file reports in compliance with either Section 13 or 15(d) of the Exchange Act, the Trust covenants that it shall file any reports required to be filed by it under the Securities Act or the Exchange Act and shall take such further action as the Holders of Registrable Securities may reasonably request, all to the extent required from time to time to enable such Holders to sell Registrable Securities (subject to any contractual obligation of such Holders to the contrary) without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 under the Securities Act, as such Rules may be amended from time to time, or any similar Rule or regulation hereafter adopted by the Commission. Upon the request of any Holder, the Trust will deliver to such Holder a written statement as to whether it has complied with such requirements.

7. Miscellaneous.

7.1. Assignment; No Third Party Beneficiaries. This Agreement and the rights, duties and obligations of the Trust hereunder may not be assigned or delegated by the Trust in whole or in part. This Agreement and the rights, duties and obligations of the Holders of Registrable Securities hereunder may be freely assigned or delegated by such Holder of Registrable Securities in conjunction with and to the extent of any transfer of Registrable Securities held by any such Holder (subject to any contractual obligation of such Holders to the contrary). This Agreement and the provisions hereof shall be binding upon and shall inure to the benefit of each of the parties hereto and their respective permitted successors and assigns; provided, however, that no such transfer or assignment shall be binding upon or obligate the Trust to any such assignee unless and until the Trust shall have received written notice of such transfer or assignment as herein provided and a written agreement of the assignee to be bound by the provisions of this Agreement. This Agreement is not intended to confer any rights or benefits on any Persons that are not party hereto other than as expressly set forth in Article 5 and this Section 7.1.

7.2. Notices. All notices, demands, requests, consents, approvals or other

communications required or permitted to be given hereunder or which are given with respect to this Agreement shall be in writing and shall be personally served, delivered by reputable overnight courier service with charges prepaid, or transmitted by hand delivery, telex or facsimile, addressed as set forth below, or to such other address as such party shall have specified most recently by written notice. Notice shall be deemed given on the date of service or transmission if personally served or transmitted by telex or facsimile; provided, however, that if such service or transmission is not on a Business Day or is after normal business hours, then such notice shall be deemed given on the next Business Day. Notice otherwise sent as provided herein shall be deemed given on the next Business Day following timely delivery of such notice to a reputable overnight courier service with an order for next-day delivery.

7.3. Severability. This Agreement shall be deemed severable, and the invalidity or unenforceability of any term or provision hereof shall not affect the validity or enforceability of this Agreement or of any other term or provision hereof. Furthermore, in lieu of any such invalid or unenforceable term or provision, the parties hereto intend that there shall be added as a part of this Agreement a provision as similar in terms to such invalid or unenforceable provision as may be possible that is valid and enforceable.

7.4. Counterparts. This Agreement may be executed by facsimile and in multiple counterparts, and all of which taken together shall constitute one and the same instrument.

7.5. Entire Agreement.

7.6. Modifications and Amendments. The provisions of this Agreement, including the

provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given unless the Trust has obtained the written consent of a Majority-In-Interest of Registrable Securities outstanding at such time.

7.7. Titles and Headings. Titles and headings of sections of this Agreement are for convenience only and shall not affect the construction of any provision of this Agreement.

7.8. Waivers and Extensions. Any party to this Agreement may waive any right, breach or default which such party has the right to waive, provided, that such waiver will not be effective against the waiving party unless it is in writing, is signed by such party, and specifically refers to this Agreement. Waivers may be made in advance or after the right waived has arisen or the breach or default waived has occurred. Any waiver may be conditional. No waiver of any breach of any agreement or provision herein contained shall be deemed a waiver of any preceding or succeeding breach thereof nor of any other agreement or provision herein contained. No waiver or extension of time for performance of any obligations or acts shall be deemed a waiver or extension of the time for performance of any other obligations or acts.

7.9. Remedies Cumulative. In the event that the Trust fails to observe or perform any covenant or agreement to be observed or performed under this Agreement, each Holder of Registrable Securities may proceed to protect and enforce its rights by suit in equity or action at law, whether for specific performance of any term contained in this Agreement or for an injunction against the breach of any such term or in aid of the exercise of any power granted in this Agreement or to enforce any other legal or equitable right, or to take any one or more of such actions, without being required to post a bond. None of the rights, powers or remedies conferred under this Agreement shall be mutually exclusive, and each such right, power or remedy shall be cumulative and in addition to any other right, power or remedy, whether conferred by this Agreement or now or hereafter available at law, in equity, by statute or otherwise.

7.10. Waiver of Trial by Jury. EACH PARTY HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES THE RIGHT TO A TRIAL BY JURY IN ANY ACTION, SUIT, COUNTERCLAIM OR OTHER PROCEEDING (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF, CONNECTED WITH OR RELATING TO THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREBY, OR THE ACTIONS OF ANY HOLDER IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT HEREOF.

7.11. Governing Law; Jurisdiction. This Agreement shall for all purposes be deemed to be made under and shall be construed in accordance with the laws of the State of New York. Any suit, action or proceeding seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement or the transactions contemplated hereby may be brought in any federal or state court located in the State of New York, and each of the parties hereby consents to the jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such suit, action or proceeding and irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of the venue of any such suit, action or proceeding in any such court or that any such suit, action or proceeding which is brought in any such court has been brought in an inconvenient forum. Process in any

such suit, action or proceeding may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the foregoing, each party agrees that service of process on such party as provided in Section 7.2 shall be deemed effective service of process on such party.

7.12. Other Registration Rights. Should the Trust grant any new registration rights to any other Person, or amend or modify the registration rights of any Person in such a way to make such registration rights more favorable to one Person than to another Person, the registration rights granted under this Agreement shall be automatically amended so as to be not less favorable to any Holder than those granted to such other Person; provided, however, that this provision shall under no circumstances require the registration of any Registrable Securities prior to the time contemplated by this Agreement.

7.13. Specific Performance. The parties hereto acknowledge that there would be no adequate remedy at law if any party fails to perform in any material respect any of its obligations hereunder, and accordingly agree that each party, in addition to any other remedy to which it may be entitled at law or in equity, shall be entitled to compel specific performance of the obligations of any other party under this Agreement in accordance with the terms and conditions of this Agreement in any court of the United States or any State thereof having jurisdiction.

7.14. Expenses. Except as otherwise provided for herein or otherwise agreed to in writing by the parties, all costs and expenses incurred in connection with the preparation of this Agreement shall be paid by the Trust.

7.15. Holdback Agreement. In connection with an underwritten primary or secondary offering to the public, each Holder of Registrable Securities agrees, subject to any exceptions that may be agreed upon at the time of such offering, not to sell or otherwise transfer or dispose of any Registrable Securities (or other securities) of the Trust held by them (other than Registrable Securities included in such offering in accordance with the terms hereof) for a period equal to the lesser of 45 days following the effective date of a Registration Statement of the Trust filed under the Securities Act or such shorter period as the managing underwriter(s) shall agree to; provided, that such Holder owns more than 10% of the outstanding Common Shares of the Trust and all other shareholders who own more than 10% of the outstanding Common Shares of the Trust and all officers and trustees of the Trust enter into similar agreements. Such agreement shall be in writing in form reasonably satisfactory to the Trust and the managing underwriter. The Trust may impose stop-transfer instructions with respect to the Registrable Securities (or other securities of the Trust) subject to the foregoing restriction until the end of said period.
