In addition, the Sub-Adviser shall provide the Trust’s custodian on each business day with information relating to all transactions concerning each Fund’s assets under the Sub-Adviser’s supervision, and shall promptly provide Adviser with such information upon the reasonable request of the Adviser;

C. In furnishing services hereunder, the Sub-Adviser shall be subject to, and shall perform in compliance with the following: (i) the Trust’s Agreement and Declaration of Trust, as the same may be modified or amended from time to time (“Declaration”); (ii) the By-Laws of the Trust, as the same may be modified or amended from time to time (“By-Laws”); (iii) the stated investment objectives, policies and restrictions of each Fund and other matters contained in the currently effective Prospectus and Statement of Additional Information of the Trust filed with the Securities and Exchange Commission (“SEC”), as the same may be modified, amended or supplemented from time to time (“Prospectus and SAI”); (iv) the Investment Company Act, the Advisers Act, the Commodity Exchange Act, as amended (“CEA”) and the rules under each, and all other federal and state laws or regulations applicable to the Trust and each Fund; (v) any applicable controlling foreign laws, regulations and regulatory requirements as set forth by applicable foreign regulatory agencies; (vi) the Trust’s compliance and other policies and procedures adopted from time to time by the Board; and (vii) the instructions of the Adviser and the Board.

The Adviser undertakes to provide the Sub-Adviser with copies or other written notice of any amendments, modifications or supplements to any such above-mentioned document.

D. Without Adviser’s prior consent to each transaction, Sub-Adviser shall have full discretionary authority as agent and attorney-in-fact, with full power of substitution and full authority in each Fund’s name, to (a) buy, sell, hold, exchange, convert or otherwise deal in any manner in any assets; (b) place orders for the execution of such assets and other transactions with or through such brokers, dealers, counter-parties, issuers, agents or arrangers as Sub-Adviser may select; (c) execute, on behalf of a Fund, such brokerage, derivatives, subscription and other agreements and documents (including, without limitation, ISDA, LSTA, and/or Master Securities Forward Transaction Agreement or MSFTA documentation) as Sub-Adviser deems necessary or

Page 3 of 15

appropriate in connection with each Fund’s investment activities; and (d) negotiate, enter into, make and perform any other contracts, agreements or other undertakings it may deem advisable in connection with the performance of the Sub-Adviser’s duties hereunder.

E. In furnishing services hereunder, the Sub-Adviser will not consult with any other sub-adviser to the Trust or the sub-adviser to any other investment company managed by the Adviser concerning transactions of each Fund in securities or other assets. (This shall not be deemed to prohibit the Sub-Adviser from consulting with any of the other sub-advisers concerning compliance with paragraphs (a) and (b) of Rule 12d3-1 under the Investment Company Act. This shall also not be deemed to prohibit consultations between current and successor sub-advisers of a Fund 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.)

F. Sub-Adviser and Adviser will each make its officers and employees available to the other from time to time at reasonable times to review investment policies of each Fund and to consult with each other regarding the investment affairs of each Fund. Sub-Adviser will report to the Board and to Adviser with respect to the implementation of such program as requested by the Board or the Adviser.

G. The Sub-Adviser at its expense, will furnish: (i) all necessary facilities and personnel, including salaries, expenses, and fees of any personnel required for the Sub-Adviser to faithfully perform its duties under this Agreement; and (ii) administrative facilities, including bookkeeping, and all equipment necessary for the efficient conduct of the Sub-Adviser’s duties under this Agreement. The Sub-Adviser shall, at its expense, bear any fees or costs associated with regulatory investigations or litigation arising from or pertaining to (i) the services provided by the Sub-Adviser under the Agreement (but excluding litigation for services provided and/or fees charged by the Adviser); and (ii) the Sub-Adviser’s general business operations that require the involvement or participation of the Adviser, the Fund, and/or any Trustee of the Fund.

H. The Sub-Adviser will select brokers and dealers to effect all portfolio transactions subject to the conditions set forth herein. The Sub-Adviser is granted authority to negotiate, open, continue and terminate brokerage accounts and other brokerage arrangements with respect to all portfolio transactions it enters into on behalf of each Fund. The Sub-Adviser will provide to the Adviser copies of all agreements regarding brokerage arrangements. The Sub-Adviser will place all necessary orders with brokers, dealers, or issuers, and will negotiate brokerage commissions, if applicable. The Sub-Adviser is directed at all times to seek to execute transactions for each Fund (i) in accordance with any written policies, practices or procedures that may be established by the Board or the Adviser from time to time and which have been provided to the Sub-Adviser or (ii) as described in the Trust’s Prospectus and SAI. In placing any orders for the purchase or sale of securities and instruments for each Fund, the Sub-Adviser is hereby authorized, to the extent permitted by applicable law, to aggregate the securities and instruments to be so purchased or sold and shall use its best efforts to obtain for each Fund best price and execution, considering all of the circumstances, and shall maintain records adequate to demonstrate compliance with this requirement. Consistent with this policy, the Sub-Adviser, in selecting broker-dealers and negotiating commission rates, will take all relevant factors into consideration, including but not limited to: the best price available; the reliability, integrity and financial condition of the broker-dealer; the size of and difficulty in executing the order; the broker’s execution capabilities; any research provided by the broker that aids the Sub-Adviser’s investment decision-making process and the value of the expected contribution of the broker-dealer to the investment performance of the applicable Fund on a continuing basis.

I. Subject to such policies and procedures as the Board may determine, the Sub-Adviser may, to the extent authorized by Section 28(e) of the Securities Exchange Act of 1934, as amended (“Exchange Act”), and as interpreted by the SEC or its staff, cause each Fund to pay a broker or dealer that provides brokerage or research services to the Adviser, the Sub-Adviser and the Fund an amount of commission for effecting a portfolio investment transaction in excess of the amount of commission another broker-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 or research services provided by such broker-dealer, viewed in terms of either that particular investment transaction or the Sub-Adviser’s overall responsibilities with respect to each Fund and other accounts to which the Sub-Adviser exercises investment discretion (as such term is defined in Section 3(a)(35) of the Exchange Act). Allocation of orders placed by the Sub-Adviser on behalf of each Fund to such broker-dealers shall be in such amounts and proportions as the Sub-Adviser shall determine in good faith in conformity with its responsibilities under applicable laws, rules and regulations. The Sub-Adviser will submit reports on such allocations to the Adviser or the Board as reasonably requested by the Adviser or the Board, in such form as may be mutually agreed to by the parties hereto, indicating the broker-dealers to whom such allocations have been made and the basis therefor. To the extent authorized by Section 28(e) and the Trust’s Board, the Sub-Adviser 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. Subject to seeking best price and execution, the Board or the Adviser may direct the Sub-Adviser to effect transactions in portfolio securities through broker-dealers in a manner that will help generate resources to pay the cost of certain expenses that the Trust is required to pay or for which the Trust is required to arrange payment.

J. The Sub-Adviser will maintain all accounts, books and records with respect to each Fund as are required of an investment sub-adviser of a registered investment company pursuant to the Investment Company Act, Advisers Act, and Commodity Exchange Act and the rules thereunder, will furnish the Adviser and the Board such periodic and special reports as they may reasonably request, and shall timely file with the SEC all forms pursuant to Section 13 of the Exchange Act, with respect to its duties as are set forth herein.

K. The Sub-Adviser shall ensure that each Fund complies with the provisions of Section 851 and Section 817(h) of the Code and the regulations thereunder, including, but not limited to, Treas. Reg. Section 1.817-5. Sub-Adviser shall be responsible for the correction of any failure under the provisions cited above attributable to its actions whether in good faith, negligent, or reckless disregard, including any penalties, taxes, and interest and for any other obligations to Contract-owners and insurance company investors in each Fund.

L. The Sub-Adviser will, unless and until otherwise directed by the Adviser or the Board, vote proxies with respect to each Fund’s securities and exercise rights in corporate actions or otherwise in accordance with the Sub-Adviser’s proxy voting guidelines, as amended from time to time, which shall be provided to the Trust and the Adviser.

M. The Sub-Adviser may execute on behalf of each Fund certain agreements, instruments and documents in connection with the services performed by it under this Agreement. These may include, without limitation, brokerage agreements, clearing agreements, account documentation, futures and options agreements, swap agreements, other investment-related agreements, and any other agreements, documents or instruments the Sub-Adviser believes are appropriate or desirable in performing its duties under this Agreement.

N. The Sub-Adviser will provide to the Adviser (i) a completed monthly compliance checklist developed for each Fund by Adviser and Sub-Adviser, (ii) quarterly reports developed for each Fund by Adviser and Sub-Adviser, and (iii) other compliance and reporting information as reasonably requested by the Adviser or the Board of Trustees from time-to-time.

O. The Sub-Adviser will review each Fund’s investment-related risk disclosures in the Prospectus and SAI, and the Sub-Adviser will certify to the Adviser on a quarterly basis that, based on the Sub-Adviser’s knowledge after due inquiry including consideration of market conditions, such disclosures appropriately address current market conditions affecting investments in the Fund.

3.	Compensation of Sub-Adviser

The Adviser will pay the Sub-Adviser a sub-advisory fee, accrued daily and payable monthly on the average daily net assets of each Fund, as specified in Schedule B to this Agreement to cover the Sub-Adviser’s services under and expenses assumed in carrying out this Agreement. The Sub-Adviser agrees that the fee rate paid to the Sub-Adviser shall not be in excess of the fee rates at equivalent asset size charged by the Sub-Adviser to any other future investment company client, registered under the Investment Company Act, being managed by the Sub-Adviser having a substantially similar investment objective, style and strategy as each Fund.

4.	Custody of Assets

Sub-Adviser shall at no time physically possess the assets of the Funds or have the assets registered in its own name or the name of its nominee, nor shall Sub-Adviser in any manner acquire or become possessed of any income, whether in kind or cash, or proceeds, whether in kind or cash, distributable by reason of selling, holding or controlling such assets of the Funds. In accordance with the preceding sentence, Sub-Adviser shall have no responsibility with respect to the collection of income, physical acquisition or the safekeeping of the assets of the Funds. All such duties of collection, physical acquisition and safekeeping shall be the sole obligation of the custodian.

5.	Liability and Indemnification

A. Except as may otherwise be provided by law, neither the Sub-Adviser nor any of its officers, members or employees (its “Affiliates”) shall be liable (i) for any losses, claims, damages, liabilities or litigation (including legal and other expenses) incurred or suffered by the Adviser or the Trust as a result of any error of judgment or mistake of law by the Sub-Adviser or its Affiliates with respect to any Fund or (ii) for any failure to recommend the purchase or sale of any security on behalf of any Fund on the basis of any information which might, in the Sub-Adviser’s reasonable opinion, constitute a violation of any federal or state laws, rules or regulations; except that nothing in this Agreement shall operate or purport to operate in any way to exculpate, waive or limit the liability of the Sub-Adviser or its Affiliates for, and the Sub-Adviser shall indemnify and hold harmless the Trust, the Adviser, all affiliated persons thereof (within the meaning of Section 2(a)(3) of the Investment Company Act) and all controlling persons (as described in Section 15 of the Securities Act of 1933, as amended (“1933 Act”)) (collectively, “Adviser Indemnitees”) against, any and all losses, claims, damages, liabilities or litigation (including reasonable legal and other expenses) to which any of the Adviser Indemnitees may become subject under the 1933 Act, the Investment Company Act, the Advisers Act, or under any other statute, or common law or otherwise arising out of or based on (i) any willful misconduct, bad faith, reckless disregard or gross negligence of the Sub-Adviser

8.	Commodity Exchange Act Matters

A. The Adviser hereby represents and warrants to the Sub-Adviser that:

(i) with respect to each Fund where the Adviser is not excluded from the definition of a commodity pool operator (“CPO”) pursuant to Commodity Futures Trading Commission (“CFTC”) Regulation 4.5, the Adviser (A) is registered as a CPO under the CEA and is a member of the National Futures Association (“NFA”) and (B) consents to being treated by the Sub-Adviser as a “qualified eligible person” as defined in the rules promulgated under the CEA for the purposes of the CEA and the regulations thereunder;

(ii) with respect to each Fund where the Adviser is excluded from the definition of a CPO pursuant to CFTC Regulation 4.5, the Adviser (A) filed the notice required by CFTC Regulation 4.5(c) and shall re-file such notice annually as required and (B) will promptly notify the Sub-Adviser if it can no longer rely on the exclusion pursuant to CFTC Regulation 4.5 with respect to a Fund; and

(iii) only with respect to any Funds that may trade swaps, the Fund is an “eligible contract participant” within the meaning of Section 1a(18) of the CEA.

B. The Sub-Adviser hereby represents and warrants to the Adviser that:

(i) the Sub-Adviser is registered with the CFTC in all capacities, if any, in which the Sub-Adviser is required under the CEA and the CFTC’s regulations to be so registered and is a member of the NFA if required to be a member thereof;

(ii) if the Sub-Adviser is exempt from registration as a commodity trading advisor (“CTA”) under CFTC Regulation 4.14(a)(8) with respect to a Fund, it has filed notice required under CFTC Regulation 4.14(a)(8) and shall re-file such notice annually as required; and

(iii) if the Adviser has filed the exclusion under CFTC Regulation 4.5 with respect to a Fund, the Sub-Adviser (A) will cause such Fund to comply with the trading limitations in CFTC Regulation 4.5 unless otherwise agreed with the Adviser, and (B) promptly will notify the Adviser if it is reasonably likely that one or more Funds will not comply with such trading limitations.

C. The Adviser and the Sub-Adviser each further agree that:

(i) to the extent that the CEA and the then-current CFTC regulations require (A) registration by such party as a CPO or CTA and/or membership with NFA with respect to any Fund, (B) specific disclosure, as applicable to the investors in any Fund, or (C) filing of reports and other documents with respect to any Fund, it shall promptly and fully comply, or take reasonable steps to cause such Fund to comply, with all such requirements;

9.	Non-Exclusivity

The services of the Sub-Adviser to the Adviser, each Fund and the Trust are not to be deemed to be exclusive, and the Sub-Adviser shall be free to render investment advisory or other services to others and to engage in other activities. Adviser has no objection to Sub-Adviser rendering such services to any other person, provided that whenever the Fund and one or more other investment advisory clients of Sub-Adviser have available funds for investment, investments suitable and appropriate for each will be allocated in a manner believed by Sub-Adviser to be equitable to each. Sub-Adviser may group orders for a Fund with orders for other funds and accounts to obtain the efficiencies that may be available on larger transactions when it determines that investment decisions are appropriate for each participating account.
