1.Appointment of Sub-Advisor

In accordance with and subject to the Management Agreement, the Manager hereby appoints the Sub-Advisor to perform the services described in Section 2 below for investment and reinvestment of such portion of the assets of each Series as may be allocated to the Sub-Advisor by the Manager, from time to time (the "Allocated Assets"), subject to the control and direction of the Manager and the Fund's Board of Directors, for the period and on the terms hereinafter set forth. The Sub-Advisor accepts such appointment and agrees to furnish the services hereinafter set forth for the compensation herein provided. The Sub-Advisor shall for all purposes herein be deemed to be an independent contractor and shall, except as expressly provided or authorized, have no authority to act for or represent the Fund or the Manager in any way or otherwise be deemed an agent of the Fund or the Manager.


2.	Obligations of and Services to be Provided by the Sub-Advisor

The Sub-Advisor will:


(a)	Provide investment advisory services, including but not limited to research, advice and supervision for the Allocated Assets of each Series.


(b)	Furnish to the Board of Directors of the Fund for approval (or any appropriate committee of such Board), and revise from time to time as conditions require, a recommended investment program for each Series consistent with each Series' respective objective(s) and policies and any specific criteria applicable to the Allocated Assets.

(c)

Implement the approved investment program for the Allocated Assets by placing orders for the purchase and sale of securities without prior consultation with the Manager and without regard to the length of time the securities have been held, the resulting rate of portfolio turnover or any tax considerations , subject always to the provisions of the Fund's registration statement, Articles of Incorporation and Bylaws and the requirements of the 1940 Act, as each of the same shall be from time to time in effect. In connection therewith, the Sub-Advisor is hereby appointed as the Series' and the Fund's agent and attorney-in-fact for the limited purposes of executing account documentation agreements (including without limitation prime brokerage agreements, International Swaps and Derivatives Association (ISDA) Master Agreements, Bond Market Association Master Repurchase and Global Master Repurchase Agreements), and other contracts and documents as the Sub-Advisor shall be requested by brokers, dealers, counterparties and other persons in connection with its management of the Series.


(d)	Advise and assist the officers of the Fund, as reasonably requested by the officers, in taking such steps as are reasonably necessary or appropriate to carry out the decisions of its Board of Directors, and any appropriate committees of such Board, regarding the general conduct of the investment business of each Series.

(e)

Maintain, in connection with the Sub-Advisor's investment advisory services provided to the Allocated Assets, compliance with the 1940 Act and the regulations adopted by the SEC thereunder and the Series' investment strategies and restrictions as stated in the Fund's prospectus and statement of additional information and any specific criteria applicable to the Allocated Assets, subject to receipt of such additional information as may be required from the Manager in accordance with Section 13(e).


(f)	Report to the Board of Directors of the Fund at such times and in such detail as the Board of Directors may reasonably deem appropriate in order to enable it to determine that the investment policies, procedures and approved investment program of each Series (and any specific criteria applicable to the Allocated Assets) are being observed.


(g)	Upon request, provide commercially reasonable assistance and recommendation for the determination of the fair value of certain securities when reliable market quotations are not readily available for purposes of calculating net asset value in accordance with procedures and methods established by the Fund's Board of Directors.

(h)

Furnish, at its own expense, (i) all necessary investment and management facilities , including salaries of clerical and other personnel employed by the Sub-Advisor required for it to execute its duties hereunder in good faith, and (ii) administrative facilities, including bookkeeping, clerical personnel and equipment necessary for the efficient conduct of its duties under this Agreement. The Sub-Advisor shall not be responsible for any expenses incurred by the Fund or the Series, except as otherwise specifically provided herein, provided that the Sub-Advisor will need prior written approval from the Manager if such expenses are initiated by the Sub-Advisor on behalf of the Fund or the Series (other than with respect to brokerage, settlement and other similar fees, commissions and expenses, which the parties agree shall be borne by the Fund).

(i)

Open accounts with Foreign Account Tax Compliance Act compliant broker-dealers and futures commission merchants ("broker-dealers"), select broker-dealers to effect all transactions for each Series, place all necessary orders with broker-dealers or issuers (including affiliated broker-dealers), and negotiate commissions, if applicable. To the extent consistent with applicable law, purchase or sell orders for each Series may be aggregated with contemporaneous purchase or sell orders of other clients of the Sub-Advisor. In such event allocation of securities so sold or purchased, as well as the expenses incurred in the transaction, will be made by the Sub-Advisor in the manner the Sub-Advisor considers to be the most equitable and consistent with its fiduciary obligations to the Fund and to other clients. The Manager recognizes that, in some cases, this procedure may limit the size of the position that may be acquired or sold for the Series. The Sub-Advisor will report on such allocations at the request of the Manager, the Fund or the Fund's Board of Directors providing such information as the number of aggregated trades to which each Series was a party, the broker-dealers to whom such trades were directed and the basis for the allocation for the aggregated trades. The Sub-Advisor shall use its best efforts to obtain execution of transactions for each Series at prices which are advantageous to the Series and at commission rates that are reasonable in relation to the benefits received. However, the Sub-Advisor may select brokers or dealers on the basis that they provide brokerage, research or other services or products to the Sub-Advisor. To the extent consistent with applicable law, the Sub-Advisor may pay a broker or dealer an amount of commission for effecting a securities transaction in excess of the amount of commission or dealer spread another broker or dealer would have charged for effecting that transaction if the Sub-Advisor determines in good faith that such amount of commission is reasonable in relation to the value of the brokerage and research products and/or services provided by such broker or dealer. This determination, with respect to brokerage and research products and/or services, may be viewed in terms of either that particular transaction or the overall responsibilities which the Sub-Advisor and its affiliates have with respect to each Series as well as to accounts over which they exercise investment discretion. Not all such services or products need be used by the Sub-Advisor in managing the Allocated Assets. In addition, joint repurchase or other accounts may not be utilized by the Series except to the extent permitted under applicable law or under any exemptive order obtained by the Sub-Advisor provided that all conditions of such order are complied with.

(j)

Maintain all accounts, books and records with respect to the Allocated Assets as are required of an investment advisor of a registered investment company pursuant to the 1940 Act and Investment Advisers Act of 1940, as amended (the "Advisers Act"), and the rules thereunder, and furnish the Fund and the Manager with such periodic and special reports as the Fund or the Manager may reasonably request. In compliance with the requirements of Rule 31a-3 under the 1940 Act, the Sub-Advisor hereby agrees that all records that it maintains for each Series are the property of the Fund, agrees to preserve for the periods described by Rule 31a-2 under the 1940 Act any records that it maintains for the Series and that are required to be maintained by Rule 31a-1 under the 1940 Act, and further agrees to surrender promptly to the Fund any records that it maintains for a Series upon request by the Fund or the Manager. The Sub-Advisor has no responsibility for the maintenance of Fund records except insofar as is directly related to the services the Sub-Advisor provides to a Series.

(k)

Observe and comply with Rule 17j-1 under the 1940 Act and the Sub-Advisor's Code of Ethics adopted pursuant to that Rule as the same may be amended from time to time. The Manager acknowledges receipt of a copy of the Sub-Advisor's current Code of Ethics. The Sub-Advisor shall promptly forward to the Manager a copy of any material amendment to the Sub-Advisor's Code of Ethics, and, upon written request, certification that the Sub-Advisor has implemented procedures for administering the Sub-Advisor's Code of Ethics.


(l)	From time to time as the Manager or the Fund may request, furnish the requesting party reports on portfolio transactions and reports on investments held by a Series, all in such detail as the Manager or the Fund may reasonably request. The Sub-Advisor will make available its

officers and employees to meet with the Fund's Board of Directors at the Fund's principal place of business on reasonable prior notice to review the investments of a Series.

(m)

Provide such information as is customarily provided by a sub-advisor , or as may be required under applicable laws or reasonably requested by the Manager, for the Fund or the Manager to comply with their respective obligations under applicable laws, including, without limitation, the Internal Revenue Code of 1986, as amended (the "Code"), the 1940 Act, the Advisers Act, the Securities Act of 1933, as amended (the "Securities Act"), and any state securities laws, and any rule or regulation thereunder . Such information includes, but is not limited to: the Sub-Advisor's compliance manual and policies and procedures adopted to comply with Rule 206(4)-7 of the Advisers Act; the Sub-Advisor's most recent annual compliance report or a detailed summary of such report; timely and complete responses to all Quarterly Compliance Questionnaires (including the identification of any material compliance matters and a copy of any material changes to the Sub-Advisor's Rule 206(4)-7 compliance policies and procedures marked to show changes along with a written summary of the purpose of each such change) , Annual Proxy Voting Questionnaires, Annual Best Execution and Soft Dollar Questionnaires, and responses to all other reasonable requests from the Manager. The Sub-Advisor agrees to make available for the Manager's review all deficiency letters issued by the SEC together with all responses given by Sub-Advisor to such letters. The Sub-Advisor will advise the Manager of any material changes in the Sub-Advisor's ownership within a reasonable time after any such change. Manager acknowledges receipt of Sub-Advisor's Form ADV more than 48 hours prior to the execution of this Agreement.

(n)

Cooperate with the Manager in its performance of quarterly and annual tax compliance tests to monitor the Series' compliance with Subchapter M of the Code and Section 817(h) of the Code. If it is determined by the Manager or its tax advisors that the Series is not in compliance with the requirements imposed by the Code, the Sub-Advisor, in consultation with the Manager and its tax advisors, will take prompt, commercially reasonable action to bring the Series back into compliance within the time permitted under the Code.


(o)	Vote proxies received on behalf of each Series (with respect to the portion thereof allocated to the Sub-Advisor) in a manner consistent with the Sub-Advisor's proxy voting policies and procedures and provide a record of votes cast containing all of the voting information required by Form N-PX in an electronic format to enable the Series to file Form N-PX as required by SEC rules.
