The Master Portfolio will, however, in no way be liable for any errors or omissions in such documents, whether or not it makes any objection thereto, except to the extent such errors or omissions result from information provided in writing by the Master Portfolio specifically for use therein. The Feeder Fund will not make any other written or oral representation about the Master Portfolio without its prior written consent.

          (d) State Street shall comply in all material respects with all applicable laws, rules, and regulations in connection with the operations of the Feeder Fund, including the requirements of the USA PATRIOT ACT of 2001 and its implementing rules and regulations (“AML Laws”).

     3.2 Indemnification by Feeder Fund.

          (a) The Feeder Fund will indemnify and hold harmless the Master Portfolio, and the Trust and its respective trustees, directors, officers and employees and each other person who controls the Master Portfolio, as the case may be, within the meaning of Section 15 of the 1933 Act (each, a “Covered Person” and collectively, “Covered Persons”), against any and all losses, claims, demands, damages, liabilities and expenses (each, a “Liability” and collectively,

the “Liabilities”) (including the reasonable cost of investigating and defending against any claims therefor and any counsel fees and expenses incurred in connection therewith), joint or several, that

               (i) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any registration statement, any prospectus, or any amendment thereof or supplement thereto, or any advertisement or sales literature, or any other document or publication filed, created, or published or otherwise disseminated by the Feeder Fund, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that the Feeder Fund will not be liable in any such case to the extent that such Liability arises out of or is based upon any untrue statement or omission in or from any thereof in reliance upon and in conformity with written information furnished to the Feeder Fund by the Master Portfolio specifically for use therein; or

               (ii) arise out of any misstatement of a material fact or an omission of a material fact included in Feeder Fund advertising or sales literature, other than information provided by the Master Portfolio or included in Feeder Fund advertising or sales literature at the request of the Master Portfolio; or

               (iii) result from the failure of any representation or warranty made by State Street on behalf of the Feeder Fund to be accurate when made or the failure of State Street or the Feeder Fund to perform any covenant contained herein or to otherwise comply with the terms of this Agreement.; or

               (iv) arise out of any failure of State Street, with respect to the Feeder Fund, or any director, officer, employee or agent of State Street, with respect to the Feeder Fund, to comply with any applicable law;

provided, however, that in no case shall the Feeder Fund be liable with respect to any claim made against any Covered Person unless the party shall have notified the Feeder Fund in writing of the nature of the claim within a reasonable time after the summons, other first legal process or formal or informal initiation of a regulatory investigation or proceeding shall have been served upon or provided to a Covered Person, or any federal, state or local tax deficiency has come to the attention of the Adviser, the Master Portfolio or a Covered Person. Failure to notify the Feeder Fund of such claim shall not relieve it from any liability that it may have to any party otherwise than on account of the indemnification contained in this Section.

          (b) The Feeder Fund will be entitled to participate at its own expense in the defense or, if it so elects, to assume the defense of any suit brought to enforce any such liability, but, if the Feeder Fund elects to assume the defense, such defense shall be conducted by counsel chosen by the Feeder Fund. In the event the Feeder Fund elects to assume the defense of any such suit and retain such counsel, each Covered Person and any other defendant or defendants may retain additional counsel, but shall bear the fees and expenses of such counsel unless (A) the Feeder Fund shall have specifically authorized the retaining of such counsel or (B) the parties to such suit include any Covered Person and the Feeder Fund, and any such Covered Person has

been advised by counsel that one or more legal defenses may be available to it that may not be available to the Feeder Fund, in which case the Feeder Fund shall not be entitled to assume the defense of such suit notwithstanding its obligation to bear the fees and expenses of such counsel. The Feeder Fund shall not be liable to indemnify any Covered Person for any settlement of any claim affected without the Feeder Fund’s written consent, which consent shall not be unreasonably withheld or delayed. The indemnities set forth in paragraph (a) will be in addition to any liability that the Feeder Fund might otherwise have to a Covered Person.

     3.3 The Trust on behalf of the Master Portfolio covenants that:

          (a) The Trust shall promptly provide all signature pages required for inclusion in any SEC Filings of the Feeder Fund, provided that the Feeder Fund is in material compliance with its covenants and obligations under this Agreement and that such SEC filings are provided to the Trust as soon as reasonably practicable prior to the filing date. State Street acknowledges that the provision of such signature pages does not constitute a representation that such SEC Filing complies with the Securities Laws or does not contain any untrue statement of a material fact or does not omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, except with respect to information provided by the Master Portfolio or its agents for inclusion in such SEC Filing, which shall in any event include any written information obtained from the Master Portfolio N-1A.

          (b) The Trust shall furnish to State Street, at least forty (40) business days prior to filing any amendments to its registration statement on Form N-1A that relate to the Master Portfolio, unless provision of such amendments is impracticable under the circumstances, in which case it shall be provided as soon as reasonably practicable. The Trust shall provide State Street with reasonable advance written notice of (1) any change in the Master Portfolio’s investment objective, (2) any material changes in the Master Portfolio’s investment policies or activities, (3) any material increase in the Master Portfolio’s fees and expenses including as a result of the termination or change of any expense waiver or reimbursement agreement, (4) any change in the Master Portfolio’s fiscal year end, or (5) any change in the time for calculating the net asset value of the Master Portfolio.

          (d) Interests in the Master Portfolio have and will continue to be: (i) offered and sold solely in private placement transactions which do not involve any “public offering” within the meaning of Section 4(2) of the 1933 Act, and (ii) are either noticed or qualified for sale or exempt from such notice or qualification requirements under applicable securities laws in those states of jurisdictions in which they are offered and sold.

          (e) The Master Portfolio shall at all times effect redemptions of Interests in accordance with the 1940 Act and the rules and regulations thereunder, the Master Portfolio N-1A and the organizational documents of the Trust. Redemption requests, other than a withdrawal of the Feeder Fund’s entire investment in the Master Portfolio, typically will be effected in cash, but the Trust reserves the right to make redemptions of securities in kind as described in the Master Portfolio’s current Prospectus. The Master Portfolio shall use its best efforts to settle redemptions on the next business day following the receipt of the redemption request and if such next business day settlement is not practicable, will immediately notify the Feeder Fund of the anticipated settlement date, which shall in all events be a date permitted by the 1940 Act.

          (f) The Master Portfolio, or its designee, shall notify the Feeder Fund, or its designee, of the Master Portfolio’s NAV and the Feeder Fund’s pro rata portion of income, expenses, and realized and unrealized gains and losses of the Master Portfolio for that business day by 6:00 pm EST on a best effort basis.

The Master Portfolio shall provide such certifications and information, in such form and for periods as is agreed to by the parties, to demonstrate the Master Portfolio’s compliance with the provisions of Rule 2a-7, but in no case will the provision of such materials occur before the Trust’s Board of Trustees has received the information contained in such materials. To the extent that Rule 2a-7 requires reporting of any event to the Board of Trustees of the Master Portfolio, the Master Portfolio shall provide notice of such event to the Feeder Fund as soon as reasonably practicable after notice is provided to the Board of Trustees of the Trust. The Master Portfolio shall provide such reports as agreed to by the parties, to enable Feeder Fund to fulfill the responsibilities of its Board of Trustees under Rule 2a-7 including, without limitation, shadow pricing reports pursuant to Rule 2a-7 at such intervals as agreed to by the parties.

          (h) The Trust shall comply in all material respects with all applicable laws, rules and regulations applicable to the operations of the Master Portfolio as a registered investment company.

               (ii) result from the failure of any representation or warranty made by the Master Portfolio to be accurate when made or the failure of the Master Portfolio to perform any covenant contained herein or to otherwise comply with the terms of this Agreement.

               (iii) arise out of any failure of the Trust, with respect to the Master Portfolio, or any director, officer, employee or agent of the Trust, to comply with any applicable law.

          (b) The Master Portfolio will be entitled to participate at its own expense in the defense or, if it so elects, to assume the defense of any suit brought to enforce any such liability, but, if the Master Portfolio elects to assume the defense, such defense shall be conducted by counsel chosen by the Master Portfolio.

The Master Portfolio shall not be liable to indemnify any Covered Person for any settlement of any claim affected without the Master Portfolio’s written consent, which consent shall not be unreasonably withheld or delayed.

The indemnities set forth in paragraph (a) will be in addition to any liability that the Master Portfolio might otherwise have to a Covered Person.

     3.6 Allocation of Losses.

          (c) If the indemnification provided for in Section 3.2 or Section 3.5 is for any reason unavailable to or insufficient to hold harmless a Covered Person in respect of any losses, claims, demands, damages, liabilities, or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of any losses, claims, demands, damages, liabilities, or expenses incurred by such Covered Person in such proportion as is appropriate to reflect the relative fault of the Feeder Fund and the Master Portfolio in connection with the statements or omissions or other action or failure to act which resulted in such losses, liabilities, claims, damages, or expenses, as well as any other relevant equitable considerations.

          (d) In the case of any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, the relative fault of the Feeder Fund and the Master Portfolio shall be determined by reference to, among other things, whether any such untrue statement or alleged untrue statement or omission or alleged omission related to information supplied by the Feeder Fund or the Master Portfolio and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission.

          (e) The Feeder Fund and the Master Portfolio agree that it would not be just and equitable if contribution pursuant to this Section 3.4 were determined by any method of allocation which does not take account of the equitable considerations referred to above in this Section 3.6. The aggregate amount of losses, claims, demands, damages, liabilities, and expenses incurred by a Covered Person and referred to above in this Section 3.6 shall be deemed to include any legal or other expenses reasonably incurred by such Covered Person in investigating, preparing, or defending against any litigation or any investigation or proceeding or any such claims and reasonable counsel fees and expenses incurred in connection therewith.
