The Adviser, upon approval of the Board of Directors, may engage one or more investment advisers that are registered as such under the Investment Advisers Act of 1940, as amended, to act as sub-adviser with respect to existing and future Portfolios of the Company. Such sub-adviser or sub-advisers shall assume such responsibilities and obligations of the Adviser pursuant to this Investment Management Agreement as shall be delegated to the sub-adviser or sub-advisers, and the Adviser will supervise and oversee the activities of any such sub-adviser or sub-advisers.

The execution of such transactions shall not be deemed to represent an unlawful act or breach of any duty created by this Agreement or otherwise. The Adviser or the sub-adviser will promptly communicate to the Board of Directors such information relating to portfolio transactions as the Board may reasonably request.

Expenses to be paid by the Company, include, but are not limited to (i) interest and taxes; (ii) brokerage commissions; (iii) premiums for fidelity and other insurance coverage requisite to the Company’s operations; (iv) the fees and expenses of its non-interested directors; (v) legal, audit and fund accounting expenses; (vi) custodian and transfer agent fees and expenses; (vii) expenses incident to the redemption of its shares; (viii) fees and expenses related to the registration under federal and state securities laws of shares of the Company for public sale; (ix) expenses of printing and mailing prospectuses, reports, notices and proxy material to shareholders of the Company; (x) all other expenses incidental to holding meetings of the Company’s shareholders; and (xi) such extraordinary non-recurring expenses as may arise, including litigation affecting the Company and any obligation which the Company may have to indemnify its officers and Directors with respect thereto. Any officer or employee of the Adviser or of any entity controlling, controlled by or under common control with the Adviser, who may

also serve as officers, directors or employees of the Company shall not receive any compensation from the Company for their services.

7. Compensation of the Adviser

As compensation for the services rendered by the Adviser, each Portfolio shall pay to the Adviser as promptly as possible after the last day of each month during the term of this Agreement, a fee accrued daily and paid monthly, as set forth in Schedule B to this Agreement, as it may be amended from time to time:

The Adviser, or an affiliate of the Adviser, may agree to subsidize any of the Portfolios to any level that the Adviser, or any such affiliate, may specify. Any such undertaking may be modified or discontinued at any time except to the extent the Adviser explicitly agrees to maintain such undertaking for a specified period.

If it is necessary to calculate the fee for a period of time that is less than a month, then the fee shall be (i) calculated at the annual rates provided in Schedule B but prorated for the number of days elapsed in the month in question as a percentage of the total number of days in such month, (ii) based upon the average of the Portfolio’s daily net asset value for the period in question, and (iii) paid within a reasonable time after the close of such period.

8. Liability of the Adviser

(a) The Adviser shall not be liable for any loss or losses sustained by reason of any investment including the purchase, holding or sale of any security, or with respect to the administration of the Company, as long as the Adviser shall have acted in good faith and with due care; provided, however, that no provision in this Agreement shall be deemed to protect the Adviser against any liability to the Company or its shareholders by reason of its willful misfeasance, bad faith or gross negligence (or, alternatively, in respect of any Portfolio for which the sub-adviser at the time of such loss is Hartford Investment Management Company, its negligence) in the performance of its duties or by reason of its reckless disregard of its obligations and duties under this Agreement.

(b) The rights of exculpation and indemnification are not to be construed so as to provide for exculpation or indemnification provided under 8(a) of any person for any liability (including liability under U.S. federal securities laws that, under certain circumstances, impose liability even on persons that act in good faith) to the extent (but only to the extent) that exculpation or indemnification would be in violation of applicable law, but will be construed so as to effectuate the applicable provisions of this section to the maximum extent permitted by applicable law.

9. Duration of Agreement

(a) This Agreement, as amended, shall be effective on March 1, 2010. This Agreement, unless sooner terminated in accordance with 9(b) below, shall continue in effect from year to year thereafter provided that its continuance is specifically approved at least annually (1) by a vote of a majority of the members of the Board of Directors of the Company or by a vote of a majority of the outstanding voting securities of each Portfolio, and (2) in either event, by the vote of a majority of the members of the Company’s Board of Directors who are not parties to this Agreement or interested persons of any such party, cast in person at a meeting called for the purpose of voting on this Agreement.

(b) This Agreement (1) may be terminated at any time without the payment of any penalty either by a vote of a majority of the members of the Board of Directors of the Company or by a vote of a majority of the Portfolio’s outstanding voting securities, on sixty days’ prior written notice to the Adviser; (2) shall immediately terminate in the event of its assignment and (3) may be terminated by the Adviser on sixty days’ prior written notice to the Portfolio, but such termination will not be effective until the Portfolio shall have contracted with one or more persons to serve as a successor investment adviser for the Portfolio and such person(s) shall have assumed such position.

(c) As used in this Agreement, the terms “assignment”, “interested person” and “vote of majority of the Company’s outstanding voting securities” shall have the meanings set forth for such terms in the 1940 Act, as amended.

(d) Any notice under this Agreement shall be given in writing, addressed and delivered, or mailed postpaid, to the other party to this Agreement to whom such notice is to be given at such party’s current address.

10. Other Activities

Nothing in this Agreement shall limit or restrict the right of any director, officer, or employee of the Adviser to engage in any other business or to devote his or her time and attention in part to the management or other aspects of any other business, whether of a similar nature or a dissimilar nature, nor to limit or restrict the right of the Adviser to engage in any other business or to render services of any kind to any other corporation, firm individual or association.

11. Additional Series

The amendment of Schedule A to this Agreement for the sole purpose of adding one or more Portfolios shall not be deemed an amendment of this Agreement or an amendment affecting an already existing Portfolio and requiring the approval of shareholders of that Portfolio.

12. Invalid Provisions

If any provision of this Agreement shall be held or made invalid by a court decision, statute, rule or otherwise, the remainder of this Agreement shall not be affected thereby.

13. Governing Law

To the extent that federal securities laws do not apply, this Agreement and all performance hereunder shall be governed by the laws of the State of Connecticut, which apply to contracts made and to be performed in the State of Connecticut.

14. Amendments

No provision of this Agreement may be changed, waived, discharged, or terminated orally, but only by an instrument in writing signed by the party against whom enforcement of the change, waiver, discharge, or termination is sought, and no amendment of this Agreement will be effective until approved in a manner consistent with the 1940 Act and rules and regulations under the 1940 Act and any applicable Securities and Exchange Commission exemptive order from such rules and regulations. Any such instrument signed by a Portfolio must be (a) approved by the vote of a majority of the Directors who are
