from an Authorized Person, GIS shall incur no liability to RS in acting upon such Oral Instruction or Written Instruction provided that GIS’s actions comply with the other provisions of this Agreement.

Section 8. Confidentiality.

GIS agrees to keep confidential all records of the Covered Portfolios and information relating to the Portfolio and its shareholders, unless the release of such records or information is otherwise consented to, in writing, by RS.

Section 9. Accountant Liaison.

GIS shall, at the request of RS, act as liaison with the Covered Portfolios’ independent registered public accountants and shall provide account analyses, fiscal year summaries, and other audit-related schedules with respect to each Covered Portfolio, as reasonably requested. GIS shall take all reasonable action in the performance of its duties under this Agreement to assure that the necessary information is made available to such accountants for the expression of their opinion, as required by the Covered Portfolio.

Such books and records shall be prepared and maintained as required by the 1940 Act and other applicable laws, rules, and regulations.

Monthly fees shall be due within ten (10) days after the end of the month to which the payment relates, or, if later, within five (5) days after the receipt of payment by

RS of the corresponding fees from the Covered Portfolio in question. RS shall not be required to make any payment hereunder in respect of services rendered by GIS relating to any Covered Portfolio for any period unless and until RS has received payment under the Investment Advisory Agreement in respect of such Covered Portfolio for such period.

(b) From and after the third anniversary of the effective date of this Agreement, RS will pay to GIS such other fee or fees as may be agreed to in writing between RS and GIS.

Section 12. Indemnification.

The Trusts, on behalf of each of their respective Covered Portfolios, separately agree to indemnify and hold harmless GIS and its affiliates from all taxes, charges, expenses, assessments, claims and liabilities (including, without limitation, liabilities arising under any state or foreign securities and blue sky laws, and amendments thereto), and reasonable expenses, including (without limitation) reasonable attorneys’ fees and disbursements, arising directly or indirectly from any action or omission to act which GIS takes in respect of that Covered Portfolio (i) at the request or on the direction of or in reliance on the advice of the Trusts or RS, acting as agent for the Trusts, or (ii) upon Oral Instructions or Written Instructions. Neither GIS, nor any of its affiliates, shall be indemnified against any liability (or any expenses incident to such liability) arising out of GIS’s or its affiliates’ own willful misfeasance, bad faith, negligence or reckless disregard of its duties and obligations under this Agreement.

Section 13. Duration and Termination.

(a) This Agreement shall remain in effect for a period of two (2) years, unless sooner terminated in accordance with paragraph (b), and shall continue in effect from year to year thereafter in respect of each Covered Portfolio so long as such continuation is approved at least annually by the Board of Trustees of the

Trust and the vote of a majority of the Trustees of the Trust who are not parties to this Agreement or interested persons of any such party, cast in person at a meeting for the purpose of voting on such approval.

(b) This Agreement may be terminated in respect of a Covered Portfolio at any time, without payment of any penalty, by the Board of Trustees of the Trust or by a vote of a majority of voting securities of such Covered Portfolio, upon sixty (60) days written notice to GIS, and by GIS upon sixty (60) days written notice to the Trust. This Agreement shall also terminate in the event of any assignment hereof, as defined in the 1940 Act, and with respect to a Covered Portfolio, upon the termination of the Advisory Agreement with respect to that Portfolio.

(c) Termination under this section shall not affect the right of GIS to receive payments on any unpaid balance of the compensation described in Section 11 earned prior to such termination.

Section 16. Amendments.

No amendment to this Agreement will be effective unless it is in writing and signed by each Party. Any amendment shall require the approval of the Board of Trustees of the Trust. Any failure of a Party to comply with any obligation, covenant, agreement or condition contained in this Agreement may be waived by the Party entitled to the benefits of the provision only by a written instrument duly executed and delivered by the Party granting the waiver, but the waiver or failure to insist upon strict compliance with such obligation, covenant, agreement or condition will not operate as a waiver of, or estoppel with respect to, any subsequent or other failure of compliance.

The captions in this Agreement are included for convenience of reference only and in no way define or delimit any of the provisions hereof or otherwise affect their construction or effect.
