None of the Fund or the Investment Advisers will be liable to the extent that such loss, claim, damage or liability arises from the sale of the Notes to any person by an Underwriter, pursuant to this Underwriting Agreement, and is based on an untrue statement or omission or alleged untrue statement or omission (1) made in reliance on and in conformity with information furnished in writing to the Fund by the Underwriters expressly for use in the document, or (2) made in the Preliminary Prospectus if the Prospectus or an amendment or supplement to the Prospectus corrects such untrue statement or omission or alleged untrue statement or omission that is the basis of the loss, claim, damage or liability for which indemnification is sought and the Fund sustains or the Investment Advisers sustain the burden of proving that a copy of the Prospectus or the amendment or supplement to the Prospectus was not sent or given (other than as a result of noncompliance by the Fund with

-12-

Section 5(e) hereof) to such person at or before the written confirmation of the sale to such person in any case where such delivery is required. This indemnity agreement will be in addition to any liability that the Fund or the Investment Advisers might otherwise have.

(b)        The Underwriter will indemnify and hold harmless the Fund and the Investment Advisers, each person, if any, who controls the Fund or the Investment Advisers, within the meaning of the 1933 Act, as though applicable, each director of the Fund or the Investment Advisers and each director of the Fund or the Investment Advisers to the same extent as the foregoing indemnity from the Fund and the Investment Advisers to the Underwriter, but only insofar as losses, claims, damages or liabilities arise out of or are based on any untrue statement or omission or alleged untrue statement or omission made in reliance on and in conformity with information furnished in writing to the Fund by the Underwriter expressly for use in preparation of the Prospectus and any amendment or supplement thereto. The Fund and the Investment Advisers acknowledge that the statements with respect to stabilization on the Prospectus and the statements with respect to the Underwriter contained therein constitute the only information furnished in writing to the Fund by the Underwriter, in its capacity as such, expressly for use in any such document. This indemnity agreement will be in addition to any liability that the Underwriter might overwise have.

(c)        The Investment Advisers will indemnify and hold harmless the Underwriter and each person, if any, who controls each Underwriter within the meaning of the 1933 Act, as though applicable, against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section 8, with respect to any advertisements or sales literature prepared by such Investment Advisers or its affiliates or the Fund for use by securities firms in connection with the offering of the Notes. In addition, the Investment Advisers will so indemnify and hold harmless the Underwriter and each person, if any, who controls the Underwriter within the meaning of the 1933 Act, as though applicable, with respect to any advertisements or sales literature prepared jointly by the Investment Advisers in connection with the offering of the Notes, provided that such indemnification will be in equal amounts.

(d)        Any party that proposes to assert the right to be indemnified under this Section 8 will, promptly after receipt of notice of commencement of any action against such party in respect of which a claim is to be made against an indemnifying party or parties under this Section 8, notify each such indemnifying party of the commencement of such action, enclosing a copy of all papers served, but the omission so to notify such indemnifying party will not relieve it from any liability that it may have to any indemnified party. No indemnification provided for in Section 8(a), (b) or (c) hereof shall be available to any party who shall fail to give notice as provided in this Section 8(d) if the party to whom notice was not given was unaware of the proceeding to which such notice would have related and was prejudiced by the failure to give such notice, but the omission so to notify such indemnifying party of such action shall not relieve it from any liability that it may have to any indemnified party for contribution or otherwise than on account of the provisions in Section 8(a), (b) or (c). If any such action is brought against any indemnified party and it notifies the indemnifying party of its commencement, the indemnifying party will be entitled to participate in, and, to the extent that it elects by delivering written notice to the indemnified party promptly after receiving notice of the commencement of the action from the indemnified party, jointly with any other indemnifying party similarly notified, to assume the defense of the action, with counsel reasonably satisfactory to the indemnified party, and, after

-13-

notice from the indemnifying party to the indemnified party of its election to assume the defense, the indemnifying party will not be liable to the indemnified party for any legal or other expenses except as provided below and except for the reasonable costs of investigation subsequently incurred by the indemnified party in connection with the defense. The indemnified party will have the right to employ its counsel in any such action, but the fees and expenses of such counsel will be at the expense of such indemnified party unless (1) the employment of counsel by the indemnified party has been authorized in writing by the indemnifying party, (2) the indemnified Party has reasonably concluded that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party) or (3) the indemnifying party has not in fact employed counsel to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action, in each of which cases the reasonable fees and expenses of counsel will be at the expense of the indemnifying party or parties. All such fees and expenses will be reimbursed promptly as they are incurred, documented and billed. Notwithstanding any other provisions of this Section 8, an indemnifying party will not be liable for any settlement of any action or claim effected without its prior written consent or, in connection with any proceeding or related proceeding in the same jurisdiction, for the fees and expenses of more than one separate counsel for all indemnified parties.

(e)        In no case shall the indemnification provided in this Section 8 be available to protect any person against any liability to which any such person would otherwise be subject by reason of willful misfeasance, bad faith or gross negligence in the performance of its or his obligations or duties hereunder, or by reason of its or his reckless disregard of its or his obligations and duties hereunder.

9.        Contribution. In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in the foregoing Section is applicable in accordance with its terms but for any reason is held to be unavailable from the Fund, the Investment Advisers or the Underwriters, the Fund, the Investment Advisers and the Underwriter will contribute to the total losses, claims, damages and liabilities (including any investigation, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action or any claims asserted, but after deducting any contribution received by the Fund or the Investment Advisers from persons other than the Underwriter, such as persons who control the Fund, or the Investment Advisers within the meaning of the 1933 Act, as though applicable, officers of the Fund or the Investment Advisers and directors of the Fund or the Investment Advisers, who may also be liable for contribution) to which the Fund or the Investment Advisers and the Underwriter may be subject in such proportion as is appropriate to reflect (i) the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party on the other hand from the offering of the Notes or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, not only such relative benefits but also the relative fault of the indemnifying party or parties on the one hand and the indemnified party on the other hand in connection with the statements or omissions or alleged statements or omissions that resulted in the losses, claims, damages or liabilities, joint or several (including any investigation, legal or other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted), for which contribution is sought. The relative benefits received by the Fund and the Investment Advisers on the one hand (treated jointly

-14-

for this purpose as one person) and the Underwriter on the other hand shall be deemed to be in the same proportion as the total proceeds from the offering (before deducting expenses) received by the Fund bear to the total selling commissions received by the Underwriter. The relative fault of the parties shall he 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 the Fund, the Investment Advisers or the Underwriter, the parties’ relative intents, knowledge, access to information and opportunity to correct or prevent such statement or omission and any other equitable considerations appropriate in the circumstances. Notwithstanding any other provisions of this Section 9, (1) the Underwriter will be responsible for any amount in excess of the selling commission applicable to the Notes sold by the Underwriter and (2) no person found guilty of fraudulent misrepresentation (within the meaning of the applicable laws of the United States or Puerto Rico) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section, any person who controls a party to this Underwriting Agreement within the meaning of the 1933 Act, as though applicable, will have the same rights to contribution as that party, directors, officers, employees and agents of the Underwriter will have the same rights to contribution as such Underwriter, directors, officers and employees of the Investment Advisers will have the same rights to contribution as the Investment Advisers, and each director and officer of the Fund and the Investment Advisers will have the same rights to contribution as the Fund, subject in each case to clause (i) of this Section. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action against such party in respect of which a claim for contribution may be made under this Section, notify such party or parties from whom contribution may be sought, but the omission so to notify will not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have otherwise than under this Section. No party will be liable for contributions with respect to any action or claim settled without its written consent.

10.        Termination.

(a)        This Underwriting Agreement shall become effective upon the date first above written, provided that this Underwriting Agreement shall not take effect unless it has first been approved by a majority of the Board of Directors of the Fund, including a majority of the independent directors in accordance with the requirements of the ICA and the rules and regulations thereunder.

(b)        Unless sooner terminated as provided herein, this Underwriting Agreement shall continue in effect for one year from its effective date. Thereafter if not terminated, this Underwriting Agreement shall continue for successive annual periods, provided that such continuance is specifically approved at least annually (a) by vote of a majority of those members of the Board of Directors who are not interested persons of any party to this Underwriting Agreement, cast in person (or otherwise, as consistent with applicable laws, regulations and related guidance and relief) at a meeting called for the purpose of voting on such approval, and (b) by the Board of Directors or by vote of a majority of the outstanding voting securities of the Fund.

This Underwriting Agreement will automatically terminate in the event of its assignment. As used in this Underwriting Agreement, the terms “majority of the outstanding voting

-15-

securities,” “interested persons” and “assignment” shall have the same meanings as such terms in the ICA.

(c)        The rights and obligations under such Underwriting Agreement may be terminated with respect to either Underwriter by notifying the Fund at any time:

(i) at or before each Closing Date, if in the judgment of such Underwriter, delivery of any Notes is rendered impracticable or inadvisable because (1) trading in the securities of the Fund is suspended by the Commission, (2) additional governmental restrictions, not in force on the date of this Underwriting Agreement, have been imposed upon trading in securities generally or trading in securities generally has been suspended on any United States securities exchange, or a general banking moratorium has been established by Federal authorities or Puerto Rico authorities, or (3) any outbreak or material escalation of hostilities or other calamity or crisis occurs the effect of which is such as to make it impracticable to market any or all of the Notes; or

(ii) at or before each Closing Date, if any of the conditions specified in Section 7 have not been fulfilled when and as required by this Underwriting Agreement.

(d)        This Underwriting Agreement may be terminated by the Fund by action of its Board of Directors, subject to the unanimous consent of the Independent Fund Directors (as defined in the Fund’s Code of Ethics), with ten (10) days prior written notice to the Underwriter.

(c)        The rights and obligations under this Underwriting Agreement may be terminated by any party with respect to such party upon notice of breach of any of the continuous representations made in this Agreement.

(d)        The rights and obligations under this Underwriting Agreement shall automatically terminate with respect to any party upon change of control of such party .

11.        Substitution of Underwriter.    If the Underwriter fails (other than for a reason sufficient to justify the termination of this Underwriting Agreement) to purchase on any Closing Date the Notes agreed to be purchased on such Closing Date by the Underwriter, the Underwriter may find one or more substitute underwriters to purchase such Notes or make such other arrangements as the Underwriter deems advisable, upon the terms set forth in this Underwriting Agreement. If no such arrangements have been made within thirty-six hours after such Closing Date, and the number of Notes to be purchased by the Underwriter on such Closing Date exceeds 10% of the Notes to be purchased on such 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 Underwriter to purchase such Shares on the terms set forth in this Underwriting Agreement.

Either the Underwriter or the Fund will have the right to postpone the applicable Closing Date for not more than five business days in order that necessary changes and arrangements (including any necessary amendments or supplements to the Prospectus) may be effected by the

-16-

Underwriter and the Fund. If the number of Notes to be purchased on such Closing Date by the Underwriter exceeds 10% of the Notes that the Underwriter is obligated to purchase on such Closing Date, and the Fund does not make arrangements pursuant to this Section 11 within the period stated for the purchase of the Notes that the Underwriter agreed to purchase, this Underwriting Agreement will terminate without liability on the part of the Fund or the Investment Advisers, except in both cases as provided in Section 5(d), 5(e), 8 and 9 hereof. This Section will not affect the liability of the Underwriter to the Fund arising out of such default. A substitute underwriter will become the Underwriter for all purposes of this Underwriting Agreement.

12.        Miscellaneous.

(a)        The reimbursement, indemnification and contribution agreements in Sections 5(d), 5(c), 5(g), 8 and 9 hereof and the representations of the Fund, the Investment Advisers and the Underwriters in this Underwriting Agreement will remain in full force and effect regardless of any termination of this Underwriting Agreement. The reimbursement, indemnification and contribution agreements in Sections 5(d), 5(e), 5(g), 8 and 9 hereof and the representations and agreements of the Fund, the Investment Adviser and the Underwriters in this Underwriting Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the Underwriters, the Fund, the Investment Adviser or any controlling person and delivery of and payment for the Notes.

(b)        This Underwriting Agreement is for the benefit of the Underwriters, the Fund, the Investment Adviser and their successors and assigns, and, to the extent expressed in this Underwriting Agreement, for the benefit of persons controlling the Underwriters, the Fund, or the Investment Adviser, directors of the Fund, directors, officers, employees and agents of the Underwriters and directors, officers and employees of the Investment Adviser, and their respective successors and assigns, and no other person, partnership, association or corporation will acquire or have any right under or by virtue of this Underwriting Agreement.
