D. Limitations on Advisory Services.

(1) The Sub-adviser shall perform the services under this Agreement subject to the review of the Adviser and the Board and in a manner consistent with the investment objectives, policies, and restrictions of the Portfolios and/or Fund as stated in the Fund’s Registration Statement filed with the Securities and Exchange Commission (the “SEC”), its Articles of Incorporation and Bylaws, each as amended from time to time, and the provisions of the Investment Company Act of 1940, as amended (the “1940 Act”).

ARTICLE III

Compensation of the Sub-adviser

A. Investment Advisory Fee. The Adviser, and not the Fund, will pay the Sub-adviser on a monthly basis for the services rendered by the Sub-adviser with respect to the Portfolios, as described in Schedule B hereto, as such Schedule may be amended from time to time by mutual written agreement. Payment will be made on or about the 15^th day of each month based on the average daily net assets of the Portfolios during the immediately preceding month.

Such expenses include the costs incurred in providing sub-advisory services pursuant to this Agreement (such as compensating and furnishing office space for officers and employees of the Sub-adviser connected with investment and economic research, trading, and investment management of the Portfolios). As described in the Advisory Agreement, the Fund and/or the Adviser pay all other expenses incurred in the operation of the Portfolios and all of its general administrative expenses. The Sub-adviser shall not be responsible for the following expenses of the Fund: organization and certain offering expenses of the Fund (including out-of-pocket expenses, but not including the Sub-adviser’s overhead and employee costs); fees payable to the Sub-adviser and to any other Fund advisers or consultants; legal expenses; auditing and accounting expenses; interest expenses; telephone, telex, facsimile, postage and other communications expenses; taxes and governmental fees; fees, dues and expenses incurred by or with respect to the Fund in connection with membership in investment company trade organizations; fees and expenses of the Fund’s administrator or of any transfer agent, registrar, or dividend disbursing agent of the Fund; payments to the administrator for maintaining the Fund’s financial books and records and calculating its daily net asset value; other payments for portfolio pricing or valuation services to pricing agents, accountants, bankers and other specialists, if any; expenses of preparing share certificates; other expenses in connection with the issuance, offering, distribution or sale of securities issued by the Fund; expenses relating to investor and public relations; expenses of registering and qualifying shares of the Fund for sale; freight, insurance and other charges in connection with the shipment of the Fund’s portfolio securities; brokerage commissions or other costs of acquiring or disposing of any portfolio securities or other assets of the Fund, or of entering into other transactions or engaging in any investment practices with respect to the Fund; expenses of printing and distributing prospectuses, Statements of Additional Information, reports, notices and dividends to stockholders; costs of stationery or other office supplies; any litigation expenses; and costs of stockholders’ and other meetings. Notwithstanding the foregoing, the Sub-advisor shall be obligated to reimburse the Fund for liabilities incurred as a result of overdrafts caused by the implementation of the Sub-adviser’s investment program for the Portfolio.

ARTICLE IV

Portfolio Transactions and Brokerage

A. Portfolio Transactions and Brokerage. The Sub-adviser agrees to determine the securities to be purchased or sold by the Portfolios, subject to the provisions of Article II regarding coordination with the Adviser and the Board, and to place orders pursuant to its determinations, either directly with the issuer, with

any broker dealer or underwriter that specializes in the securities for which the order is made, or with any other broker or dealer selected by the Sub-adviser, subject to the following limitations.

(1) The Sub-adviser is authorized to select the brokers or dealers that will execute the purchases and sales of securities for the Portfolios and will use its best efforts to obtain the most favorable net results and execution of the Portfolio’s orders, taking into account all appropriate factors, including price, dealer spread or commission, if any, size of the transaction, and difficulty of the transaction.

(2) The Sub-adviser is specifically authorized to allocate brokerage and principal business to firms that provide such services or facilities and to cause the Fund to pay a member of a securities exchange or any other securities broker or dealer an amount of commission for effecting a securities transaction in excess of the amount of commission another member of an exchange, broker or dealer would have charged for effecting that transaction, if the Sub-adviser determines in good faith that such amount of commission is reasonable in relation to the value of the brokerage and research services (as such services are defined in Section 28(e) of the Securities Exchange Act of 1934, as amended (the “1934 Act”)) provided by such member, broker or dealer, viewed in terms of either that particular transaction or the Sub-adviser’s over-all responsibilities with respect to the accounts as to which it exercises investment discretion (as that term is defined in Section 3(a)(35) of the 1934 Act). The Sub-adviser shall regularly report to the Adviser and the Board with respect to the brokerage commissions incurred by the Portfolios for the purchases and sales of its portfolio securities. The Adviser and the Board will review the amount of such brokerage commissions and consult with the Sub-adviser in that regard.

(3) Subject to the above requirements and compliance with the provisions of the 1940 Act, 1934 Act, and other applicable provisions of law, and the terms of any exemption(s) therefrom, nothing shall prohibit the Sub-adviser from selecting brokers or dealers with which it or the Fund are affiliated.

ARTICLE V

Activities of the Sub-adviser

A. Exclusivity; Supplemental Investment Research.

(1) The services of the Sub-adviser under this Agreement are not to be deemed exclusive and the Sub-adviser will be free to render similar services or other services to others so long as the Sub-adviser fulfills its rights and obligations under this Agreement. It is understood that directors, officers, employees and shareholders of the Fund are or may become interested in the Sub-adviser, as directors, officers, employees or shareholder or otherwise, and that directors, officers, employees or shareholder of the Sub-adviser are or may become similarly interested in the Fund, and that the Sub-adviser is or may become interested in the Fund as shareholder or otherwise.

(2) It is agreed that the Sub-adviser may use any supplemental investment research obtained for the benefit of the Portfolios in providing investment advice to its other investment advisory accounts. In addition, the Sub-adviser or its affiliates may use such information in managing their own accounts. Conversely, such supplemental information obtained by the Sub-adviser for the benefit of its accounts and other accounts it advises may be considered by and may be useful to the Sub-adviser in carrying out its obligations to the Fund.

B. Investment Transactions. Securities held by the Portfolios may also be held by other separate accounts or mutual funds for which the Sub-adviser or its affiliates act as an adviser or sub-adviser, or by the Sub-adviser or its affiliates. Because of different investment objectives or other factors, a particular security may be bought by the Sub-adviser or its affiliates or for one or more clients when one or more clients are selling the same security. In accordance with applicable law, if purchases or sales of securities for the Portfolios or other entities for which the Sub-adviser or its affiliates act as investment adviser or sub-adviser or for their advisory clients arise for consideration at or about the same time, the Fund and Adviser agree that the Sub-adviser may make transactions in such securities, insofar as feasible, for the respective entities and clients in a manner deemed equitable to all. To the extent that transactions on behalf of more than one client of the Sub-adviser during the same period may increase the demand for securities being purchased or the supply of securities being sold, the Fund recognizes that there may be an adverse effect on the price thereof.

C. Aggregate Transactions. It is agreed that, on occasions when the Sub-adviser deems the purchase or sale of a security to be in the best interests of the Portfolios as well as other accounts or companies, it may, to the extent permitted by applicable laws and regulations, but will not be obligated to, aggregate the securities to be so sold or purchased for other accounts or companies and the Portfolios in order to obtain favorable execution and low brokerage commissions. In that event, allocation of the investments purchased or sold, as well as the expenses incurred in the transaction, will be made by the Sub-adviser in the manner it considers to be most equitable and consistent with its fiduciary obligations to the Portfolios and to such other accounts or companies. The Fund recognizes that in some cases this procedure may adversely affect the size of the position obtainable for the Portfolios.

ARTICLE VI

A. Effectiveness. This Agreement shall not become effective (and the Sub-adviser shall not serve or act hereunder) unless and until it is approved by the Board, including a majority of directors who are not parties to this Agreement or interested persons of any such party to this Agreement, and, to the extent required under applicable laws, rules, regulations and/or exemptive orders issued by the SEC, by a majority of the shareholders of each of the Portfolios.

In connection with such approvals, the Board shall request and evaluate, and the Sub-adviser shall furnish, such information as may be reasonably necessary to evaluate the Sub-adviser’s performance hereunder.

C. Termination. This Agreement:

(1) shall not be terminated by the Sub-adviser without 60 days prior written notice to Adviser;

(4) may be terminated upon written notice from Adviser to Sub-adviser in the event Sub-advisor materially breaches its obligations or any representation or warranty hereunder.

D. Amendment. This Agreement may be amended only by a written instrument signed by the Fund, the Adviser and the Sub-adviser; provided that no material amendment of this Agreement shall be effective without specific approval of such amendment by the Board, including a majority of those directors who are not parties to this Agreement or interested persons of such a party, cast in person at a meeting called for the purpose of voting on such approval.

ARTICLE VII

Recordkeeping

The Sub-adviser agrees that all accounts and records which it maintains for the Portfolios shall be the property of the Fund and that it will surrender promptly to the designated officers of the Fund any or all such accounts and records upon request. The Sub-adviser further agrees to preserve all records prescribed by the rules and regulations of the SEC and applicable law for such periods of time as prescribed by such rules and regulations and applicable law. The Sub-adviser also agrees that it will maintain all records and accounts regarding its investment activities hereunder in a confidential manner and will not disclose the same to any third party; provided, however, that the Sub-adviser may make such records and accounts available to its legal counsel, independent auditors and other third party service providers that have a legitimate need to know such information and are themselves subject to a confidentiality requirement with respect to such information. All such accounts or records shall be made available, within five business days of the request, to the Fund’s accountants or auditors during regular business hours at the Sub-adviser’s offices upon reasonable prior written notice. In addition, the Sub-adviser will provide any materials, reasonably related to the investment sub-advisory services provided hereunder, as may be reasonably requested in writing by the

directors or officers of the Fund or as may be required by any governmental agency or self-regulatory organization having jurisdiction hereof.

ARTICLE VIII

A. Indemnification of Adviser and Fund by Sub-adviser. The Sub-adviser agrees and undertakes to hold harmless, indemnify and protect the Fund and Adviser and their directors, officers, employees, agents, subsidiaries and affiliates from and against any and all damage, loss, liability and expense (including without limitation reasonable attorneys’ fees and expenses in connection with any action, suit or proceeding) (each, a “Loss” and, collectively, the “Losses”) incurred or suffered by the Fund or Adviser as a result of (1) any breach of any representation or warranty, covenant or agreement made herein by Sub-adviser, or (2) the activities (or omissions by the Sub-adviser to carry out its obligations hereunder) of the Sub-adviser under this Agreement, including the activities (or such omissions) of the Sub-adviser’s directors, officers, employees, agents, subsidiaries, affiliates or any person or entity retained by Sub-adviser to perform or assist in the performance of its obligations hereunder; provided, however, that in no event is Sub-adviser’s indemnity in favor of the Fund or Adviser deemed to protect the Fund or Adviser against any liability to which the Fund or Adviser would otherwise be subject by reason of willful misfeasance, bad faith, or gross negligence in the performance of their duties or by reason of their reckless disregard of its obligations or duties under this Agreement or the Advisory Agreement. Neither Sub-adviser nor its affiliates shall be liable for any Loss or damage arising or resulting from the acts or omissions of the custodian of the Portfolio, any broker, financial institution or any other third party with or through whom Sub-adviser arranges or enters into a transaction in respect of the Portfolio, except to the extent that Sub-adviser or its affiliate instructed such broker, financial institution or third party to take such action or omission. Adviser understands and acknowledges that Sub-adviser does not warrant that the Portfolio will achieve any particular rate of return or that its performance will match any benchmark index or other standard or objective and the Sub-adviser shall not be liable for any Loss due solely to a mistake of investment judgment.

B. Indemnification of Sub-adviser by Adviser. The Adviser agrees and undertakes to hold harmless, indemnify and protect the Sub-adviser from and against any and all Losses incurred or suffered by Sub-adviser as a result of (1) any breach of any representation or warranty, covenant or agreement made herein by Adviser, or (2) the activities of the Adviser under this Agreement and the Advisory Agreement (or omissions by the Adviser to carry out its obligations hereunder or thereunder), including the activities (or such omissions) of the Adviser’s directors, officers, employees, agents, subsidiaries and affiliates; provided, however, that in no event is Adviser’s indemnity in favor of Sub-adviser deemed to protect Sub-adviser against any liability to which the Sub-adviser would otherwise be subject by reason of willful misfeasance,

bad faith, or gross negligence in the performance of its duties or by reason of its reckless disregard of its obligations or duties under this Agreement.

C. Indemnification Related to Disclosure Documents.

(1) The Fund and the Adviser, jointly and severally, agree to hold harmless the Sub-adviser, its directors and officers, and each person, if any, who controls the Sub-adviser within the meaning of either Section 15 of the Securities Act of 1933, as amended (the “1933 Act”) or Section 20 of the 1934 Act from and against any and all Losses arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in the Fund’s Registration Statement, or any amendment or supplement thereto, or in any preliminary prospectus, any other communication with investors or any other submissions to governmental bodies or self-regulatory agencies filed or distributed on or subsequent to the date first above-written (such documents being herein referred to as “Disclosure Documents”) or arising out of or based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities or expenses arise out of or are based upon any such untrue statement or omission or allegation thereof based upon information furnished in writing to the Fund or the Adviser by the Sub-adviser which the Fund or Adviser had informed the Sub-adviser was to be used, or which the Sub-adviser had acknowledged was to be used, in the particular Disclosure Document.

(2) The Sub-adviser agrees to indemnify and hold harmless the Fund and the Adviser, their directors and officers, and each person, if any, who controls the Fund or the Adviser within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act to the same extent as the foregoing indemnity from the Fund and the Adviser to the Sub-adviser, but only with respect to information furnished in writing by it which the Fund or Adviser had informed the Sub-adviser was to be used in the Disclosure Documents. In case any action or proceeding shall be brought against the Fund or the Adviser, their directors or officers, or any such controlling persons, in respect of which indemnity may be sought against the Sub-adviser, the Sub-adviser shall have the rights and duties given to the Fund and the Adviser, and the Fund or the Adviser, their directors or officers, or such controlling persons shall have the rights and duties given to the Sub-adviser, by the preceding paragraph.

D. Limitation of Liability. In no event shall any party be liable to any other party for special, consequential, punitive, incidental, exemplary or similar damages or losses regardless of the grounds or nature of any claim asserted (including without limitation contract, xxxxxxx, xxxxxxxxxx, xxxx, xxxxxx liability or otherwise) and whether or not the party seeking the indemnification was advised of the possibility of the damage or loss asserted.

E. Procedures.

(1) The party seeking indemnification under this Article VIII (the “Indemnified Party”) agrees to give prompt written notice of any claims for indemnification (“Claims”) to the party against whom indemnity is sought (the “Indemnifying Party”), including any and all facts constituting the basis for such Claim.

(2) In the event of any Claim for indemnification hereunder resulting from or in connection with any claim or legal proceeding by a third party (a “Third Party Assertion”), the Indemnified Party shall promptly give written notice thereof to the Indemnifying Party. In the event of any such Claim resulting from or in connection with a Third Party Assertion, the Indemnifying Party shall assume the defense thereof, provided, however, that the Indemnifying Party shall first have agreed in writing that it does not and will not contest its responsibility for indemnifying the Indemnified Party in respect of Claims attributable to such Third Party Assertion in accordance with the terms hereof. If an Indemnifying Party assumes the defense of any such Third Party Assertion, the Indemnifying Party shall be entitled to select counsel, which counsel shall be reasonably acceptable to the Indemnified Party, be obligated to pay the reasonable costs (including reasonable attorney’s fees and expenses) incurred by the Indemnified Party in defending such Third Party Assertion between the date of the commencement of such Third Party Assertion and the date of the Indemnifying Party’s assumption of such defense, and take all steps necessary in the defense thereof; provided, further, that the Indemnified Party may, at its own expense, participate in any such proceeding with the counsel of its choice without any right of control thereof.

(3) So long as the Indemnifying Party is in good faith defending such Third Party Assertion, the Indemnified Party shall not compromise or settle such Third Party Assertion without the prior written consent of the Indemnifying Party and will cooperate with the Indemnifying Party and provide any information reasonably requested by the Indemnifying Party. If the Indemnifying Party does not assume the defense of any such Third Party Assertion, the Indemnified Party shall take such steps as are necessary in the defense thereof in such manner as it may deem appropriate, including, but not limited to, settling such Third Party Assertion on such terms as the Indemnified Party may deem appropriate and the Indemnifying Party will promptly indemnify the Indemnified Party in accordance with the provisions of this Article VIII; provided, however, that if the Indemnifying Party does not consent in writing to any such settlement, and such written consent is not unreasonably withheld by the Indemnifying Party, the Indemnified Party shall not be entitled to indemnification hereunder from such Indemnifying Party with respect to the Third Party Assertion settled.

(4) Failure of any party hereto to give notice as required under this Article VIII will not affect or diminish the indemnification obligations of the party entitled to receive such notice, except to the extent that (and only to such extent) the failure to receive notice materially prejudiced the rights of such party.
