E. The Subadviser will select brokers and dealers to effect all Portfolio transactions subject to the conditions set forth herein. The Subadviser will place all necessary orders with brokers, dealers, or issuers, and will negotiate brokerage commissions if applicable. The Subadviser is directed at all times to seek to execute brokerage transactions for the Portfolio in accordance with such policies or practices as described in the current Prospectus as amended from time to time. In placing orders for the purchase or sale of investments for the Portfolio, in the name of the Portfolio or their nominees, the Subadviser shall use its best efforts to obtain for the Portfolio the most favorable price and best execution available, considering all of the circumstances, and shall maintain records adequate to demonstrate compliance with this requirement.

Subject to the appropriate policies and procedures approved by the Adviser and the Board, and provided to the Subadviser in writing, the Subadviser may, but shall be under no obligation to, to the extent authorized by Section 28(e) of the Securities Exchange Act of 1934, cause the Portfolio to pay a broker or dealer that provides brokerage or research services to the Subadviser, an amount of commission for effecting a portfolio transaction in excess of the amount of commission another broker or dealer would have charged for effecting that transaction if the Subadviser determines, in good faith, that such amount of commission is reasonable in relationship to the value of such brokerage or research services provided viewed in terms of that particular transaction or the Subadviser’s overall responsibilities to the Portfolio or its other advisory clients. To the extent authorized by said Section 28(e) and the Adviser and the Board, the Subadviser shall not be deemed to have acted unlawfully or to have breached any duty created by this Agreement or otherwise solely by reason of such action. The Subadviser will consult with the Adviser to the end that portfolio transactions on behalf of a Portfolio are directed to broker-dealers that participate in commission recapture programs benefiting the Portfolio, provided that neither the Subadviser nor the Adviser will direct brokerage in recognition of the sale of Portfolio shares.

The Adviser understands and agrees that, should there be a failed trade for the Portfolio that has a material effect on such Portfolio, as determined by the Subadviser, the Subadviser in its discretion either will file a compensation claim with the broker responsible for the failed trade or otherwise make the Portfolio whole for any loss incurred.

F. On occasions when the Subadviser deems the purchase or sale of a security to be in the best interest of a Portfolio as well as other clients of the Subadviser, the Subadviser to the extent permitted by applicable laws and regulations, and subject to the Adviser approval of the Subadviser’s trade aggregation and allocation procedures, may, but shall be under no obligation to, aggregate the orders for securities to be purchased or sold to attempt to obtain a more favorable price or lower brokerage commissions and efficient execution. In such event, allocation of the securities so purchased or sold, as well as the expenses incurred in the transaction, will be made by the Subadviser in the manner set forth in the Subadviser’s trade aggregation and allocation procedures.

G. With respect to the provision of services by the Subadviser hereunder, the Subadviser will maintain all accounts, books and records with respect to each Portfolio as are required of an investment adviser of a registered investment company pursuant to the 1940 Act and the Advisers Act and the rules under both statutes.

H. The Subadviser and the Adviser acknowledge that the Subadviser is not the compliance agent for the Portfolio, and does not have access to all of the Company’s books and records necessary to perform certain compliance testing. However, to the extent that the Subadviser has agreed to perform the services specified in this Agreement, the Subadviser shall perform compliance testing with respect to the Portfolio based upon information in its possession and upon information and written instructions received from the Adviser or the Administrator and shall not be held in breach of this Agreement so long as it performs in accordance with such information and instructions. The Adviser or Administrator shall promptly provide the Subadviser with copies of the Company’s Articles of Incorporation, By-Laws, current Prospectus and any written policies or procedures adopted by the Board applicable to the Portfolio and any amendments or revisions thereto, and Subadviser shall not be required to comply with any such documents until its receipt thereof or formal notice of the changes requiring immediate compliance.

I. The Subadviser will have no duty to vote any proxy solicited by or with respect to the issuers of securities in which assets of the Portfolios are invested unless the Adviser gives the Subadviser written instructions to the contrary. If provided with such notice, the Subadviser will vote proxies for the Portfolio according to the Subadviser’s voting policies. The Subadviser will immediately forward any proxy solicited by or with respect to the issuers of securities in which assets of the Portfolios are invested to the Adviser or to any agent of the Adviser designated by the Adviser in writing.

The Subadviser will make appropriate personnel available for consultation for the purpose of reviewing with representatives of the Adviser and/or the Board any proxy solicited by or with respect to the issuers of securities in which assets of the Portfolios are invested. Upon request, the Subadviser will submit a written voting recommendation to the Adviser for such proxies. In making such recommendations, the Subadviser shall use its good faith judgment to act in the best interests of the Portfolios. The Subadviser shall disclose to the best of its knowledge any conflict of interest with the issuers of securities that are the subject of such recommendation including whether such issuers are clients or are being solicited as clients of the Subadviser or of its affiliates.

J. Subadviser hereby authorizes Adviser to use Subadviser’s name and any applicable trademarks in the Company’s Prospectus, as well as in any advertisement or sales literature used by the Adviser or its agents to promote the Company and/or to provide information to shareholders of the Portfolio. Upon termination of this Agreement, the Company and the Adviser shall as soon as is reasonably possible cease to use such names and applicable trademarks.

During the term of this Agreement, the Adviser shall furnish to the Subadviser at its principal office all prospectuses, proxy statements, reports to shareholders, advertisements, sales literature, or other material prepared for distribution to shareholders of the Company or the public, which refer to the Subadviser or its clients in any way, prior to the use thereof, and the Adviser shall not use any such materials if the Subadviser reasonably objects within five business days (or such other time as may be mutually agreed) after receipt thereof. The Adviser shall ensure that materials prepared by employees or agents of the Adviser or its affiliates that refer to the Subadviser or its clients in any way are consistent with the prospectus and those materials previously approved by the Subadviser.

3. Compensation of Subadviser. For the services provided to each Series, the Adviser will pay the Sub-Adviser an annual fee equal to the amount specified for such Series in Schedule A hereto, payable monthly in arrears. The fee will be appropriately prorated to reflect any portion of a calendar month that this Agreement is not in effect among the parties. In accordance with the provisions of the Advisory Agreement, the Adviser is solely responsible for the payment of fees to the Sub-Adviser, and the Sub-Adviser agrees to seek payment of its fees solely from the Adviser.

4. Liability of Subadviser. Neither the Subadviser nor any of its directors, officers, employees or agents shall be liable to the Adviser or the Company for any loss or expense suffered by the Adviser or the Company resulting from its acts or omissions as Subadviser to the Portfolio, except for losses or expenses to the Adviser or the Company resulting from willful misconduct, bad faith, or gross negligence in the performance of, or from reckless disregard of, the Subadviser’s duties under this Agreement. Neither the Subadviser nor any of its agents shall be liable to the Adviser or the Company for any loss or expense suffered as a consequence of any action or inaction of other service providers to the Company in failing to observe the instructions of the Adviser, provided such action or inaction of such other service providers to the Company is not a result of the willful misconduct, bad faith or gross negligence in the performance of, or from reckless disregard of, the duties of the Subadviser under this Agreement.

5. Non-Exclusivity. The services of the Subadviser to the Portfolio[s] and the Company are not to be deemed to be exclusive, and the Subadviser shall be free to render investment advisory or other services to others (including other investment companies) and to engage in other activities, provided however, that the Subadviser may not consult with any other sub-adviser of the Company concerning transactions in securities or other assets for any investment portfolio of the Company, including the Portfolio[s], except that such consultations are permitted between the current and successor sub-advisers of a portfolio in order to effect an orderly transition of sub-advisory duties so long as such consultations are not concerning

transactions prohibited by Section 17(a) of the Investment Company Act of 1940, as amended. It is understood and agreed that the directors, officers, and employees of the Subadviser are not prohibited from engaging in any other business activity or from rendering services to any other person, or from serving as partners, officers, directors, trustees, or employees of any other firm or corporation, including other investment companies.

6. Adviser Oversight and Cooperation with Regulators. The Adviser and Subadviser shall cooperate with each other in providing records, reports and other materials to regulatory and administrative bodies having proper jurisdiction over the Company, the Adviser and the Subadviser, in connection with the services provided pursuant to this Agreement; provided, however, that this agreement to cooperate does not apply to the provision of information, reports and other materials which either the Subadviser or Adviser reasonably believes the regulatory or administrative body does not have the authority to request or which is privileged or confidential information of the Subadviser or Adviser.

7. Records. The records relating to the services provided under this Agreement required to be established and maintained by an investment adviser under applicable law or those required by the Adviser or the Board of Directors for the Subadviser to prepare and provide shall be the property of the Company and shall be under its control; however, the Company shall permit the Subadviser to retain such records (either in original or in duplicate form) as it shall reasonably require. In the event of the termination of this Agreement, such records shall promptly be returned to the Company by the Subadviser free from any claim or retention of rights therein; provided however, that the Subadviser may retain copies thereof. Each party to this Agreement shall keep confidential any nonpublic information concerning the other party’s (or any Subadviser’s) duties hereunder and shall disclose such information only if the non-disclosing party has authorized such disclosure or if such disclosure is expressly required or requested by applicable federal or state regulatory authorities.
