(ll)No “prohibited transaction” as defined under Section 406 of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”) or Section 4975 of the Internal Revenue Code of 1986, as amended (the “Code”) and not exempt under Section 408 of ERISA and the regulations and published interpretations thereunder has occurred or is reasonably expected to occur (including upon the execution and delivery of this Agreement) with respect to any “employee benefit plan” (as defined in Section 3(3) ERISA, each an “Employee Benefit Plan”)) maintained by the Parent or its subsidiaries.  Neither the Parent nor the Issuer nor any of their ERISA Affiliates maintains or contributes to any “multiemployer plan” as defined in Section 3(37) of ERISA or any multiple employer plan for which the Parent or the Issuer or any ERISA Affiliate has incurred or could incur liability under Section 4063 or 4064 of ERISA and the Parent and the Issuer do not have any obligations under any collective bargaining agreement with any union and no organization efforts are underway with respect to Parent or Issuer employees.  Each Employee Benefit Plan maintained by the Parent or the Issuer or any of their ERISA Affiliates which is intended to be qualified under Section 401(a) of the Code, has received a favorable determination or opinion letter from the Internal Revenue Service that such plan is so qualified, and, to the knowledge of the Parent and the Issuer, nothing has occurred, whether by action or failure to act, that could reasonably be expected to cause the loss of such qualification.  Neither the Parent, nor the Issuer nor any of their ERISA Affiliates maintains or is required to contribute to an employee welfare plan which provides retiree or other post-employment welfare benefits or insurance coverage (other than “continuation coverage” (as defined in Section 602 of ERISA) or as otherwise required by applicable law).  Each Employee Benefit Plan of the Parent or the Issuer or their ERISA Affiliate that is subject to the funding rules of Section 412 of the Code or Section 302 of ERISA, the minimum funding standard of Section 412 of the Code or Section 302 of ERISA, as applicable, has been satisfied (without taking into account any waiver thereof or extension of any amortization period) and is reasonably expected to be satisfied in the future (without taking into account any waiver thereof or extension of any amortization period).  The fair market value of the assets of each Employee Benefit Plan that is an employee pension benefit plan within the meaning of ERISA Section 3(2) maintained by the Parent or the Issuer or their ERISA Affiliate exceeds the present value of all benefits accrued under such Employee Benefit Plan (determined based on those assumptions used to fund such Plan).  No “reportable

15

event” (within the meaning of Section 4043(c) of ERISA) has occurred or is reasonably expected to occur that either has resulted, or could reasonably be expected to result, in material liability to the Parent, the Issuer or their ERISA Affiliates.  Neither the Parent, nor the Issuer, nor any ERISA Affiliate has incurred, nor reasonably expects to incur, any liability under Title IV of ERISA (other than contributions to the Plan or premiums to the Pension Benefit Guaranty Corporation (“PBGC”), in the ordinary course and without default) in respect of an Employee Benefit Plan (including a “multiemployer plan”, within the meaning of Section 4001(a)(3) of ERISA). None of the Parent, the Issuer, any of their subsidiaries or any of their Employee Benefit Plans is the subject of an audit or investigation by the Internal Revenue Service, the U.S. Department of Labor, the PBGC or any other federal or state governmental agency relating to any Employee Benefit Plan or is the subject of any lawsuit, arbitration, mediation or other claim relating to any Employee Benefit Plan (other than claims for benefits submitted in the ordinary course).  For the purpose of this paragraph, an ERISA Affiliate means any member of the company’s controlled group as defined in Code Section 414(b), (c), (m) or (o).

(mm)There is and has been no failure on the part of the Parent and any of the Parent’s directors or officers, in their capacities as such, to comply with any provision of the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated in connection therewith (the “Sarbanes-Oxley Act”), including the establishment and maintenance of disclosure controls and procedures, Section 402 related to loans and Sections 302 and 906 related to certifications.

No part of the proceeds of the offering will be used, directly or indirectly, in violation of the FCPA or the U.K. Bribery Act 2010, each as may be amended, or similar law of any other relevant jurisdiction, or the rules or regulations thereunder.

(oo)The operations of the Obligors and their subsidiaries are and have been conducted at all times in compliance with applicable financial recordkeeping and reporting requirements and the money laundering statutes and the rules and regulations thereunder and any related or similar rules, regulations or guidelines, issued, administered or enforced by any governmental agency (collectively, the “Money Laundering Laws”) and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Obligors or any of their subsidiaries with respect to the Money Laundering Laws is pending or, to the best knowledge of the Obligors, threatened.

(pp)Neither of the Obligors, nor any of their subsidiaries nor, to the knowledge of the Obligors, any director, officer, agent, employee or affiliate of the Obligors or any of their subsidiaries (i) is, or is controlled or 50% or more owned in the aggregate by or is acting on behalf of, one or more individuals or entities that are currently the subject of any sanctions administered or enforced by the United States (including any administered or enforced by the Office of Foreign Assets Control of the U.S. Department of the Treasury, the U.S. Department of State or the Bureau of Industry and Security of the U.S. Department of Commerce), the United Nations Security Council, the European Union, a member state of the European Union (including sanctions administered or enforced by Her Majesty’s Treasury of the United Kingdom) or other relevant sanctions authority (collectively, “Sanctions” and such persons, “Sanctioned Persons” and each such person, a “Sanctioned Person”), (ii) is located, organized or resident in a country or territory that is, or whose government is, the subject of Sanctions that broadly prohibit dealings with that country or territory (collectively, “Sanctioned Countries” and each, a “Sanctioned Country”) or (iii) will, directly or indirectly, use the proceeds of this offering, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other individual or entity in any manner that would result in a violation of any Sanctions by, or could result in the imposition of Sanctions against, any individual or entity (including any individual or entity participating in the offering, whether as underwriter, advisor, investor or otherwise).

(qq)Neither of the Obligors, nor any of their subsidiaries has engaged in any dealings or transactions with or for the benefit of a Sanctioned Person, or with or in a Sanctioned Country, in the preceding 3 years, nor do the Obligors or any of their subsidiaries have any plans to engage in dealings or transactions with or for the benefit of a Sanctioned Person, or with or in a Sanctioned Country.

(rr)Except as set forth in the Disclosure Package and the Final Prospectus, the Obligors and their subsidiaries have good and marketable title to all personal property owned by them, free and clear of all encumbrances and defects; and all personal property held under lease by the Obligors or any of their subsidiaries is held by it under valid, subsisting and enforceable leases, in each case, with such exceptions as are not material and do not interfere with the use made and proposed to be made of such property by the Obligors or any of their subsidiaries.

17

(ss)No relationship, direct or indirect, exists between or among either of the Obligors on the one hand, and the directors, executive officers, or shareholders of either of the Obligors on the other hand, which is required to be described in the Registration Statement, the Disclosure Package and the Final Prospectus and which is not so described.

(tt)Commencing with its taxable year ended December 31, 1994, the Parent has been organized and has operated in conformity with the requirements for qualification and taxation as a real estate investment trust (a “REIT”) under the Code and all applicable regulations under the Code, and its proposed method of operation will enable it to meet the requirements for qualification and taxation as a REIT under the Code and all applicable regulations under the Code. The Parent presently intends to continue to qualify as a REIT under the Code and all applicable regulations under the Code for all subsequent years, and the Parent, after reasonable inquiry and diligence, does not know of any event that would reasonably be expected to cause the Parent to fail to qualify as a REIT at any time. Each of the Parent’s corporate subsidiaries that has elected, together with the Parent, to be a taxable REIT subsidiary is in compliance with all requirements applicable to a “taxable REIT subsidiary” within the meaning of Section 856(l) of the Code and all applicable regulations under the Code, and the Parent, after reasonable inquiry and diligence, is not aware of any fact that would negatively impact such qualification. Each of the Parent’s corporate subsidiaries (or subsidiaries taxable as corporations for U.S. federal income tax purposes) that is not a “taxable REIT subsidiary” is a “qualified REIT subsidiary” within the meaning of Section 856(i) of the Code and all applicable regulations under the Code.

(uu)The Issuer is and has been at all times classified as a partnership, and not as an association or partnership taxable as a corporation, for federal income tax purposes.

(vv)There are no transfer taxes or other similar fees or charges under Federal law or the laws of any state, or any political subdivision thereof, required to be paid in connection with the execution and delivery of this Agreement or the issuance by the Issuer or sale by the Issuer of the Securities.

18

“Stock Options”) and all other awards (“Other Awards”) granted pursuant to any equity incentive plan of the Parent and its subsidiaries within the past seven (7) years, (i) each Stock Option designated by the Parent at the time of grant as an “incentive stock option” under Section 422 of the Code, so qualifies, (ii) each grant of a Stock Option and each grant of an Other Award was duly authorized no later than the date on which the grant of such Stock Option or Other Award, as the case may be, was by its terms to be effective (the “Grant Date”) by all necessary corporate action, including, as applicable, approval by the board of directors of the Parent (or a duly constituted and authorized committee thereof) and any required stockholder approval by the necessary number of votes or written consents, and the award agreement governing such grant (if any) was duly executed and delivered by each party thereto, (iii) each such grant of a Stock Option or an Other Award was made in accordance with the terms of such equity incentive plan, the Exchange Act and all other applicable laws and regulatory rules or requirements, including the rules of the New York Stock Exchange (“NYSE”) and any other exchange on which Parent securities are traded, (iv) the per share exercise price of each Stock Option or Other Award in the form of a stock appreciation right or similar award was equal to or greater than the fair market value of a share of the Parent’s common stock (the “Common Stock”) on the applicable Grant Date, (v) at the time of grant and at all times thereafter, all Stock Options and Other Awards qualified for an exemption from Sections 162(m) and 409A of the Code, (vi) each grant of a Stock Option and each grant of an Other Award was made in material compliance with all applicable laws (including but not limited to applicable securities and tax laws), the recipients and holders of all Stock Options and Other Awards have received timely and complete information, in the form of a prospectus when required, regarding the terms conditions, securities laws, and tax consequences relating to their Stock Options and Other Awards as the case may be, and (vii) each such grant of a Stock Option or an Other Award was properly accounted for in accordance with GAAP in the financial statements (including the related notes) of the Parent and disclosed in the Parent’s filings with the Commission in accordance with the Exchange Act and all other applicable laws. The Parent has not knowingly granted, and there is no and has been no policy or practice of the Parent of granting, Stock Options or Other Awards in the form of stock appreciation rights or similar awards prior to, or otherwise coordinating the grant of such awards with, the release or other public announcement of material information regarding the Parent or its subsidiaries or their results of operations or prospects.

(a)Prior to the termination of the offering of the Securities, the Obligors will not file any amendment of the Registration Statement or supplement (including the Final Prospectus or any Preliminary Prospectus) to the Base Prospectus unless the Obligors have furnished you a copy for your review prior to filing and will not file any such proposed amendment or supplement to which you reasonably object. The Obligors will cause the Final Prospectus, properly completed, and any supplement thereto to be filed in a form approved by the Representatives with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed and will provide evidence satisfactory to the Representatives of such timely filing.

22

(b)If, at any time prior to the filing of the Final Prospectus pursuant to Rule 424(b), any event or development occurs as a result of which the Disclosure Package would include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made or the circumstances then prevailing not misleading, the Obligors will (i) notify promptly the Representatives so that any use of the Disclosure Package may cease until it is amended or supplemented; (ii) amend or supplement the Disclosure Package to correct such statement or omission; and (iii) supply any amendment or supplement to you in such quantities as you may reasonably request.

(c)If, at any time when a prospectus relating to the Securities is required to be delivered under the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), any event occurs as a result of which the Final Prospectus as then supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein in the light of the circumstances under which they were made at such time not misleading, or if it shall be necessary to amend the Registration Statement, file a new registration statement or supplement the Final Prospectus to comply with the Act or the Exchange Act or the respective rules thereunder, including in connection with use or delivery of the Final Prospectus, the Obligors promptly will (i) notify the Representatives of any such event, (ii) prepare and file with the Commission, subject to the second sentence of paragraph (a) of this Section 5, an amendment or supplement or new registration statement which will correct such statement or omission or effect such compliance, (iii) use its commercially reasonable best efforts to have any amendment to the Registration Statement or new registration statement declared effective as soon as practicable in order to avoid any disruption in use of the Final Prospectus and (iv) supply any supplemented Final Prospectus to you in such quantities as you may reasonably request.

(e)The Obligors will furnish to the Representatives and counsel for the Underwriters, without charge, signed copies of the Registration Statement (including exhibits thereto) and to each other Underwriter a copy of the Registration Statement (without exhibits thereto) and, so long as delivery of a prospectus by an Underwriter or dealer may be required by the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), as many copies of each Preliminary Prospectus, the Final Prospectus and each Issuer Free Writing Prospectus and any supplement thereto as the Representatives may reasonably request. The Obligors will pay the expenses of printing or other production of all documents relating to the offering.

(f)The Obligors will arrange, if necessary, for the qualification of the Securities for offering and sale under the laws of such jurisdictions as the Representatives

(i)the representations and warranties of the Obligors in this Agreement are true and correct on and as of the Closing Date with the same effect as if made on the Closing Date and each of the Obligors complied with all the

(h)At the Execution Time and at the Closing Date, the Representatives shall have received a certificate signed by the Chief Financial Officer of the Parent certifying as to the preparation, completeness and accuracy of certain financial and statistical data relating to the Parent and the Issuer included or incorporated by reference in the Registration Statement, the Disclosure Package or the Final Prospectus.

7.Reimbursement of Underwriters’ Expenses. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 10 hereof or because of any refusal, inability or failure on the part of the Issuer or the Parent to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Issuer or the Parent will reimburse the Underwriters severally through the Representatives on demand for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities.

8.Indemnification and Contribution. (a) Each of the Obligors, jointly and severally, agree to indemnify and hold harmless each Underwriter, the directors, officers, employees, affiliates and agents of each Underwriter and each person who controls any Underwriter within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (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 the Registration Statement for the registration of the Securities as originally filed or in any amendment thereof, or in the Base Prospectus, any Preliminary Prospectus or any other preliminary prospectus supplement relating to the Securities, the Final Prospectus, or any Issuer Free Writing Prospectus, or in any amendment thereof or supplement thereto, or arise out of or are 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, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Obligors will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Obligors by or on behalf of any Underwriter through the Representatives specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Obligors may otherwise have.

(b)Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Obligors, each of the Parent’s directors, each of the Issuer’s and the Parent’s officers who signs the Registration Statement, and each person who controls the Obligors within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Obligors to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Obligors by or on behalf of such Underwriter through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have. Each of the Obligors acknowledge that the following statements set forth in the Preliminary

29

Prospectus and the Final Prospectus under the heading “Underwriting”: (i) the names of the Underwriters and (ii) the sixth, seventh and eighth paragraphs thereof related to stabilization, syndicate covering transactions and penalty bids, constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in any Preliminary Prospectus, the Final Prospectus or any Issuer Free Writing Prospectus.

(c)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 the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to 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. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent (A) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and (B) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

30

(d)In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Obligors and the Underwriters severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending the same) (collectively “Losses”) to which the Obligors and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Obligors on the one hand and by the Underwriters on the other from the offering of the Securities; provided, however, that in no case shall any Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Securities) be responsible for any amount in excess of the underwriting discount or commission applicable to the Securities purchased by such Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Obligors and the Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Obligors on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Obligors shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by them as set forth on the cover page of the Final Prospectus, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions as set forth on the cover page of the Final Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Issuer or by the Parent on the one hand or by the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Obligors and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls an Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee, affiliate and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Issuer or the Parent within the meaning of either the Act or the Exchange Act, each officer of the Issuer or the Parent who shall have signed the Registration Statement and each director of the Issuer or the Parent shall have the same rights to contribution as the Obligors, subject in each case to the applicable terms and conditions of this paragraph (d).

9.Default by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the principal amount of Securities agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in

31

the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Securities set forth opposite their names in Schedule I hereto bears to the aggregate principal amount of Securities set forth opposite the names of all the remaining Underwriters) the principal amount of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the principal amount of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule I hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of such principal amount of Securities, and if such nondefaulting Underwriters do not purchase all of such principal amount of Securities, this Agreement will terminate without liability to any nondefaulting Underwriter or the Obligors. In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order that the required changes in the Registration Statement and the Final Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Obligors and any nondefaulting Underwriter for damages occasioned by its default hereunder.

10.Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Issuer and the Parent prior to delivery of and payment for the Securities, if at any time prior to such time (i) trading of any securities issued by the Parent shall have been suspended by the Commission or the NYSE or trading in securities generally on the NYSE shall have been suspended or limited or minimum prices shall have been established on such Exchange, (ii) a banking moratorium shall have been declared either by Federal or New York State authorities, (iii) there shall have occurred a material disruption in commercial banking or securities settlement or clearance services, (iii) there shall have occurred any downgrading in the rating of any debt securities or preferred stock of the Issuer or the Parent by any “nationally recognized statistical rating organization” (as defined for purposes of Section 3(a)(62) under the Exchange Act), or any public announcement that any such organization has under surveillance or review its rating of any debt securities or preferred stock of the Issuer or the Parent (other than an announcement with positive implications of a possible upgrading, and no implication of a possible downgrading, of such rating), (iv) the Issuer or the Parent or any of their subsidiaries shall have sustained a substantial loss by fire, flood, accident or other calamity which renders it impracticable, in the reasonable judgment of the Representatives, to consummate the sale of the Securities and the delivery of the Securities by the Underwriters at the initial public offering price or (v) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representatives, impractical or inadvisable to proceed with the offering, sale or delivery of the Securities as contemplated by the Disclosure Package or the Final Prospectus (exclusive of any supplement thereto).

11.Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Obligors or the officers of

32

the Issuer or the Parent, and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, the Obligors or any of the officers, directors, employees, agents, affiliates or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement.

15.Recognition of the U.S. Special Resolution Regimes.

(a)     In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b)     In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are
