Delivery by the Underwriters of any such amendments or supplements to the Prospectus will not constitute a waiver of any of the conditions in Section 6 hereof.

(d) The Managing Representative must have received on the Closing Date a certificate, dated such date, of the President, a Vice President or Managing Director and the chief financial or accounting officer of the Fund, and of the President, a Vice President or Managing Director of each of the Advisors certifying that (i) the signers have examined the Registration Statement, the Prospectus, and this Underwriting Agreement, (ii) the representations of the Fund (with respect to the certificates from such Fund officers) and the representations of the Advisors (with respect to the certificates from such officers of the Advisors) in this Underwriting Agreement are accurate on and as of the date of the certificate, (iii) there has not been any material adverse change in the general affairs, prospects, management, business, financial condition or results of operations of the Fund (with respect to the certificates from such Fund officers) or the Advisors (with respect to the certificates from such officers of the Advisors), which change would materially and adversely affect the ability of the Fund or the Advisors, as the case may be, to fulfill its obligations under this Underwriting Agreement or the Advisory Agreements, whether or not arising from transactions in the ordinary course of business, (iv) with respect to the Fund only, to the knowledge of such officers after reasonable investigation, no order suspending the effectiveness of the Registration Statement, prohibiting the sale of any of the APS or otherwise having a material adverse effect on the Fund has been issued and no proceedings for any such purpose are pending before or threatened by the Commission or any other regulatory body, whether foreign or domestic, (v) to the knowledge of the officers of the Advisors, after reasonable investigation, no order having a material adverse effect on the ability of the Advisors to fulfill its obligations under this Underwriting Agreement or the Advisory Agreements, as the case may be, has been issued and no proceedings for any such purpose are pending before or threatened by the Commission or any other regulatory body, whether foreign or domestic, and (vi) each of the Fund (with respect to the certificates from such Fund officers) and the Advisors (with respect to the certificates from such officers of the Advisors) has performed all of its respective agreements that this Underwriting Agreement requires it to perform by the Closing Date (to the extent not waived in writing by the Managing Representative).

(e) You must have received on the Closing Date the opinions, dated the Closing Date, substantially in the form of Schedules B and C to this Underwriting Agreement from the counsel identified in each such Schedule, or in such other form as is acceptable to counsel for the Underwriters.

(f) You must have received on the Closing Date from Xxxxxxxx Chance US LLP an opinion, dated the Closing Date, with respect to the Fund, the APS, the Registration Statement and the

Such opinion and proceedings shall fulfill the requirements of this Section 6(f) only if such opinion and proceedings are satisfactory in all respects to the Managing Representative. The Fund and the Advisors must have furnished to such counsel such documents as counsel may reasonably request for the purpose of enabling them to render such opinion.

(g) The Managing Representative must have received on the date this Underwriting Agreement is signed and delivered by you a signed letter, dated such date, substantially in the form of Schedule D to this Underwriting Agreement from the firm of accountants designated in such Schedule. The Managing Representative also must have received on the Closing Date a signed letter from such accountants, dated as of the Closing Date, confirming on the basis of a review in accordance with the procedures set forth in their earlier letter that nothing has come to their attention during the period from a date not more than five business days before the date of this Underwriting Agreement, specified in the letter, to a date not more than five business days before the Closing Date, that would require any change in their letter referred to in the foregoing sentence.

(h) The APS shall have been accorded a rating of "Aaa" by Xxxxx'x Investors Service, Inc., and a letter to such effect, dated on or before the Closing Date, shall have been delivered to the Managing Representative.

7. Termination. This Underwriting Agreement may be terminated by the Managing Representative by notifying the Fund at any time:

(a) before the later of the effectiveness of the Registration Statement and the time when any of the APS are first generally offered pursuant to this Underwriting Agreement by the Managing Representative to dealers by letter or telegram;

(b) at or before the Closing Date if, in the sole judgment of the Managing Representative, payment for and delivery of any APS is rendered impracticable or inadvisable because (i) trading in the APS or the Common Shares of the Fund is suspended by the Commission or the principal exchange that lists the Common Shares, (ii) trading in securities generally on the New York Stock Exchange or the Nasdaq Stock Market shall have been suspended or limited or minimum or maximum prices shall have been generally established on such exchange or over-the-counter market, (iii) additional material governmental restrictions, not in force on the date of this Underwriting Agreement, have been imposed upon trading in securities or trading has been suspended on any U.S. securities exchange, (iv) a general banking moratorium has been established by U.S. federal or New York authorities or (v) any material adverse change in the financial or securities markets in the United States or in political, financial or economic conditions in the United States or any outbreak or material escalation of hostilities or declaration by the United States of a national emergency or war or other calamity or crisis shall have occurred the effect of any of which is such as to make it, in the sole judgment of the Managing Representative,

impracticable or inadvisable to market the APS on the terms and in the manner contemplated by the Prospectus; or

(c) at or before the Closing Date, if any of the conditions specified in Section 6 have not been fulfilled when and as required by this Underwriting Agreement.

8. Substitution of Underwriters. If one or more of the Underwriters fails (other than for a reason sufficient to justify the termination of this Underwriting Agreement) to purchase on the Closing Date the APS agreed to be purchased on the Closing Date by such Underwriter or Underwriters, the Managing Representative may find one or more substitute underwriters to purchase such APS or make such other arrangements as the Managing Representative deems advisable, or one or more of the remaining Underwriters may agree to purchase such APS in such proportions as may be approved by the Managing Representative, in each case upon the terms set forth in this Underwriting Agreement. If no such arrangements have been made within 36 hours after the Closing Date, and

(a) the number of APS to be purchased by the defaulting Underwriters on the Closing Date does not exceed 10% of the APS that the Underwriters are obligated to purchase on such Closing Date, each of the nondefaulting Underwriters will be obligated to purchase such APS on the terms set forth in this Underwriting Agreement in proportion to their respective obligations under this Underwriting Agreement, or

(b) the number of APS to be purchased by the defaulting Underwriters on the Closing Date exceeds 10% of the APS to be purchased by all the Underwriters on the Closing Date, the Fund will be entitled to an additional period of 24 hours within which to find one or more substitute underwriters reasonably satisfactory to the Managing Representative to purchase such APS on the terms set forth in this Underwriting Agreement.

Upon the occurrence of the circumstances described in the foregoing paragraph (b), either the Managing Representative or the Fund will have the right to postpone the Closing Date for not more than five business days in order that necessary changes and arrangements (including any necessary amendments or supplements to the Registration Statement or the Prospectus) may be effected by the Managing Representative and the Fund. If the number of APS to be purchased on the Closing Date by such defaulting Underwriter or Underwriters exceeds 10% of the APS that the Underwriters are obligated to purchase on the Closing Date, and none of the nondefaulting Underwriters or the Fund makes arrangements pursuant to this Section within the period stated for the purchase of the APS that the defaulting Underwriters agreed to purchase, this Underwriting Agreement will terminate without liability on the part of any nondefaulting Underwriter, the Fund or the Advisors, except as provided in Sections 5(g) and 9 hereof. Any action taken under this Section will not affect the liability of any defaulting Underwriter to the Fund or to the nondefaulting Underwriters arising out of such default. A substitute underwriter will become an Underwriter for all purposes of this Underwriting Agreement.

9. Indemnity and Contribution.

(a) Each of the Fund and the Advisors, jointly and severally, agrees to indemnify, defend and hold harmless each Underwriter, its partners, directors and officers, and any person who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the successors and assigns of all of the foregoing persons from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which, jointly or severally, any such Underwriter or any such person may incur under the Act, the Exchange Act, the Investment Company Act, the Advisers Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Fund) or in a Prospectus (the term "Prospectus" for the purpose of this Section 9 being deemed to include any

Preliminary Prospectus, any Sales Materials, the Prospectus and the Prospectus as amended or supplemented by the Fund), or arises out of or is based upon any omission or alleged omission to state a material fact required to be stated in either such Registration Statement or Prospectus or necessary to make the statements made therein (with respect to the Prospectus, in light of the circumstances under which they were made) not misleading, except insofar as any such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in and in conformity with information furnished in writing by or on behalf of any Underwriter to the Fund or the Advisors expressly for use with reference to any Underwriter in such Registration Statement or such Prospectus or arises out of or is based upon any omission or alleged omission to state a material fact in connection with such information required to be stated in such Registration Statement or such Prospectus or necessary to make such information (with respect to the Prospectus, in light of the circumstances under which they were made) not misleading, provided, however, that the indemnity agreement contained in this subsection (a) with respect to any Preliminary Prospectus or amended Preliminary Prospectus shall not inure to the benefit of any Underwriter (or to the benefit of any person controlling such Underwriter) from whom the person asserting any such loss, damage, expense, liability or claim purchased the APS which is the subject thereof if the Prospectus corrected any such alleged untrue statement or omission and if such Underwriter failed to send or give a copy of the Prospectus to such person at or prior to the written confirmation of the sale of such APS to such person, unless the failure is the result of noncompliance by the Fund with Section 5(d) hereof.

If any action, suit or proceeding (together, a "Proceeding") is brought against an Underwriter or any such person in respect of which indemnity may be sought against the Fund or the Advisors pursuant to the foregoing paragraph, such Underwriter or such person shall promptly notify the Fund and the Advisors in writing of the institution of such Proceeding and the Fund or the Advisors shall assume the defense of such Proceeding, including the employment of counsel. Such Underwriter or such person shall have the right to employ its or their own counsel in any such case, but the reasonable fees and expenses of such counsel shall be at the expense of such Underwriter or of such person unless the employment of such counsel shall have been authorized in writing by the Fund or the Advisors, as the case may be, in connection with the defense of such Proceeding or the Fund or the Advisors shall not have, within a reasonable period of time in light of the circumstances, employed counsel to have charge of the defense of such Proceeding or such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from, additional to or in conflict with those available to the Fund or the Advisors (in which case neither the Fund nor the Advisors shall have the right to direct the defense of such Proceeding on behalf of the indemnified party or parties, but the Fund or the Advisors, as the case may be, may employ counsel and participate in the defense thereof but such fees and expenses of such counsel shall be at the expense of the Fund or the Advisors, as the case may be), in any of which events such reasonable fees and expenses shall be borne by the Fund or the Advisors and paid as incurred (it being understood, however, that the Fund or the Advisor shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel) in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding). Neither the Fund nor the Advisors shall be liable for any settlement of any Proceeding effected without its written consent but if settled with the written consent of the Fund or the Advisors, the Fund or the Advisors, as the case may be, agrees to indemnify and hold harmless any Underwriter and any such person from and against any loss or liability by reason of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened Proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such Proceeding and does not include an admission of fault, culpability or a failure to act, by or on behalf of such indemnified party.

(b) Each Underwriter severally agrees to indemnify, defend and hold harmless the Fund and the Advisors, and each of their respective shareholders, partners, managers, members, trustees, directors and officers, and any person who controls the Fund or the Advisors within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which, jointly or severally, the Fund or the Advisors or any such person may incur under the Act, the Exchange Act, the Investment Company Act, the Advisers Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in and in conformity with information furnished in writing by or on behalf of such Underwriter to the Fund or the Advisors expressly for use with reference to such Underwriter in the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Fund) or in a Prospectus, or arises out of or is based upon any omission or alleged omission to state a material fact in connection with such information required to be stated in such Registration Statement or such Prospectus or necessary to make such information not misleading (with respect to the Prospectus, in light of the circumstances under which they were made).

If any Proceeding is brought against the Fund, the Advisors or any such person in respect of which indemnity may be sought against any Underwriter pursuant to the foregoing paragraph, the Fund, the Advisors or such person shall promptly notify such Underwriter in writing of the institution of such Proceeding and such Underwriter shall assume the defense of such Proceeding, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses; provided, however, that the omission to so notify such Underwriter shall not relieve such Underwriter from any liability which such Underwriter may have to the Fund, the Advisors or any such person or otherwise. The Fund, the Advisors or such person shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of the Fund, the Advisors or such person, as the case may be, unless the employment of such counsel shall have been authorized in writing by such Underwriter in connection with the defense of such Proceeding or such Underwriter shall not have, within a reasonable period of time in light of the circumstances, employed counsel to have charge of the defense of such Proceeding or such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from or additional to or in conflict with those available to such Underwriter (in which case such Underwriter shall not have the right to direct the defense of such Proceeding on behalf of the indemnified party or parties, but such Underwriter may employ counsel and participate in the defense thereof but such fees and expenses of such counsel shall be at the expense of such Underwriter), in any of which events such fees and expenses shall be borne by such Underwriter and paid as incurred (it being understood, however, that such Underwriter shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel) in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding). No Underwriter shall be liable for any settlement of any such Proceeding effected without the written consent of such Underwriter but if settled with the written consent of such Underwriter, such Underwriter agrees to indemnify and hold harmless the Fund, the Advisors and any such person from and against any loss or liability by reason of such settlement. 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 the second sentence of this paragraph, then 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 60 business days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 30 days' prior notice of its intention to settle. No indemnifying party shall, without the prior written

consent of the indemnified party, effect any settlement of any pending or threatened Proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such Proceeding and does not include an admission of fault, culpability or a failure to act, by or on behalf of such indemnified party.

(c) If the indemnification provided for in this Section 9 is unavailable to an indemnified party under subsections (a) and (b) of this Section 9 in respect of any losses, damages, expenses, liabilities or claims referred to therein, then each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, damages, expenses, liabilities or claims (i) in such proportion as is appropriate to reflect the relative benefits received by the Fund and the Advisors on the one hand and the Underwriters on the other hand from the offering of the APS 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 Fund and the Advisors on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such losses, damages, expenses, liabilities or claims, as well as any other relevant equitable considerations. The relative benefits received by the Fund and the Advisors on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the total proceeds from the offering of the APS (net of underwriting discounts and commissions but before deducting expenses) received by the Fund and the total underwriting discounts and commissions received by the Underwriters, bear to the aggregate public offering price of the APS. The relative fault of the Fund and the Advisors on the one hand and of the Underwriters on the other shall be determined by reference to, among other things, whether the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by the Fund or the Advisors or by the Underwriters 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, damages, expenses, liabilities and claims referred to in this subsection shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with investigating, preparing to defend or defending any Proceeding.

(d) The Fund, the Advisors 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 subsection (c) above. Notwithstanding the provisions of this Section 9, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the APS underwritten by such Underwriter and distributed to the public were offered to the public exceeds the amount of any damage which such Underwriter has otherwise been required to pay by reason of such untrue statement or alleged untrue statement or omission or alleged omission. 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. The Underwriters' obligations to contribute pursuant to this Section 9 are several in proportion to their respective underwriting commitments and not joint.

(e) The indemnity and contribution agreements contained in this Section 9 and the covenants, warranties and representations of the Fund contained in this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of any Underwriter, its partners, directors or officers or any person (including each partner, officer or director of such person) who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, or by or on behalf of the Fund or the Advisors, its shareholders, partners, managers, members, trustees, directors or officers or any person who controls the Fund or the Advisors within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and shall survive any termination of this Agreement or the issuance and delivery of the APS. The Fund and the Advisors and each Underwriter agree promptly to notify each other of the commencement of any Proceeding against it and, in the case of the Fund or the Advisors, against any of the Fund's or the Advisors' shareholders, partners, managers, members, trustees, directors or officers in connection with the issuance and sale of the APS, or in connection with the Registration Statement or Prospectus.

(f) The Fund and the Advisors each acknowledge that the statements with respect to (1) the public offering of the APS as set forth on the cover page of, and (2) the information under the caption "Underwriting" in, the Prospectus constitute the only information furnished in writing to the Fund by the Underwriters expressly for use in such document. The Underwriters severally confirm that these statements are correct in all material respects and were so furnished by or on behalf of the Underwriters severally for use in the Prospectus.

(g) Notwithstanding any other provisions in this Section 9, no party shall be entitled to indemnification or contribution under this Underwriting Agreement against any loss, claim, liability, expense or damage arising by reason of such person's willful misfeasance, bad faith, gross negligence or reckless disregard of its duties in the performance of its duties hereunder.

proceeding or counterclaim brought in any such court shall be conclusive and binding upon the Fund and the Advisors, as the case may be, and may be enforced in any other courts in the jurisdiction of which the Fund or the Advisors, as the case may be, is or may be subject, by suit upon such judgment.

13. Parties at Interest.
