PFPC Trust will not be responsible for any assets until actual receipt.

(b) Receipt and Disbursement of Money. PFPC Trust, acting upon Written Instructions, shall open and maintain a separate account for each separate Portfolio of the Fund (each an “Account”) and shall maintain in the Account of a particular Portfolio all Property, cash and other assets received from or for the Fund specifically designated to such Account.

PFPC Trust shall make cash payments from or for the Account of a Portfolio only for:

(i) purchases of securities in the name of a Portfolio, PFPC Trust, PFPC

(iv) payment to, subject to receipt of Written Instructions, the Fund’s transfer agent, as agent for the shareholders, of an amount equal to the amount of dividends and distributions stated in the Written Instructions to be distributed in cash by the transfer agent to shareholders, or, in lieu of paying the Fund’s transfer agent, PFPC Trust may arrange for the direct payment of cash dividends and distributions to shareholders in accordance with procedures mutually agreed upon from time to time by and among the Fund, PFPC Trust and the Fund’s transfer agent;

All such securities and non-cash Property shall be held or disposed of only upon Written Instructions or otherwise pursuant to the terms of this Agreement. PFPC Trust shall have no power

or authority to withdraw, deliver, assign, hypothecate, pledge or otherwise dispose of any such securities or investment, except upon the express terms of this Agreement or upon Written Instructions authorizing the transaction. In no case may any member of the Fund’s Board of Trustees or any officer, employee or agent of the Fund withdraw any securities upon their mere receipt.

At PFPC Trust’s own expense and for its own convenience, PFPC Trust may enter into sub-custodian agreements with other banks or trust companies to perform duties with respect to domestic assets.

(vii) release securities belonging to a Portfolio to any bank or trust company for the purpose of a pledge or hypothecation to secure any loan incurred by the Fund on behalf of that Portfolio; provided, however, that securities shall be released only upon payment to PFPC Trust of the monies borrowed, except that in cases where additional collateral is required to secure a borrowing already made, subject to proper prior authorization, further securities may be released for that purpose; and repay such loan upon redelivery to it of the securities pledged or hypothecated therefor and upon surrender of the note or notes evidencing the loan;

(viii) release and deliver securities owned by a Portfolio in connection with any repurchase agreement entered into on behalf of that Portfolio, but only on receipt of payment therefor; and pay out monies of the Portfolio in connection with such repurchase agreements, but only upon the delivery of the securities;

(e) Use of Book-Entry System or Other Depository. PFPC Trust will deposit in Book-Entry Systems and other securities depositories all securities belonging to the Portfolios eligible for deposit therein and will utilize Book-Entry Systems and other securities depositories to the extent possible in connection with settlements of purchases and sales of securities by the Portfolios, and deliveries and returns of securities loaned, subject to repurchase agreements or used as collateral in connection with borrowings. PFPC Trust shall continue to perform such duties until it receives Written Instructions or Oral Instructions authorizing contrary actions. Notwithstanding anything in this Agreement to the contrary, PFPC Trust’s use of a Book-Entry System shall comply with the requirements of Rule 17f-4 under the 1940 Act.

PFPC Trust shall administer a Book-Entry System or other securities depository as follows:

(i) With respect to securities of each Portfolio which are maintained in a Book-Entry System or another securities depository, the records of PFPC Trust shall identify by book-entry or otherwise those securities as belonging to each Portfolio.

(ii) Assets of each Portfolio deposited in a Book-Entry System or another securities depository will (to the extent consistent with applicable law and standard practice) at all times be segregated from any assets and cash controlled by PFPC Trust in other than a fiduciary or custodian capacity but may be commingled with other assets held in such capacities.

PFPC Trust will provide the Fund with such reports on its own system of internal

control as the Fund may reasonably request from time to time. In addition, PFPC Trust will provide the Fund with copies of any report obtained by PFPC Trust on the system of internal accounting control of the Book-Entry System promptly after receipt of such a report by PFPC Trust.

(f) Registration of Securities. All securities held for a Portfolio which are issued or issuable only in bearer form, except such securities maintained in the Book-Entry System or in another depository, shall be held by PFPC Trust in bearer form; all other securities maintained for a Portfolio may be registered in the name of the Fund on behalf of that Portfolio, PFPC Trust, a Book-Entry System, another depository, a sub-custodian, or any duly appointed nominee of the Fund, PFPC Trust, Book-Entry System, depository or sub-custodian. The Fund reserves the right to instruct PFPC Trust as to the method of registration and safekeeping of the securities of the Fund. The Fund agrees to furnish to PFPC Trust appropriate instruments to enable PFPC Trust to maintain or deliver in proper form for transfer, or to register in the name of its nominee or in the name of the Book-Entry System or in the name of another appropriate entity, any securities which it may maintain for the Accounts. With respect to uncertificated securities which are registered in the name of the Fund or a Portfolio (or a nominee thereof), PFPC Trust will reflect such securities on its records based upon the holdings information provided to it by the issuer of such securities, but notwithstanding anything in this Agreement to the contrary PFPC Trust shall not be obligated to safekeep such securities or to perform other duties with respect to such securities other than to make payment for the purchase of such securities upon receipt of

Oral or Written Instructions, accept in sale proceeds received by PFPC Trust upon the sale of such securities of which PFPC Trust is informed pursuant to Oral or Written Instructions, and accept in other distributions received by PFPC Trust with respect to such securities or reflect on its records any reinvested distributions with respect to such securities of which it is informed by the issuer of the securities.

(g) Voting. Neither PFPC Trust nor its nominee shall vote any of the securities held pursuant to this Agreement by or for the account of a Portfolio, except in accordance with Written Instructions. PFPC Trust, directly or through the use of another entity, shall execute in blank and promptly deliver all notices, proxies and proxy soliciting materials received by PFPC Trust as custodian of the Property to the registered holder of such securities. If the registered holder is not the Fund on behalf of a Portfolio, then Written Instructions or Oral Instructions must designate the person who owns such securities.

(q) Fund Information Requests. PFPC Trust will provide such information relating to the Fund as the Fund may reasonably request in connection with the services provided by PFPC Trust to the Fund pursuant to this Agreement, provided, however, that if responding to such a request would cause an undue burden on PFPC Trust or would cause PFPC Trust to bear undue expense, PFPC Trust at its option may decline such request or shall be entitled to such fees or reimbursement of expense as agreed to by the Fund and PFPC Trust.

(i) by the Fund, on ninety (90) days prior written notice, as may be required by and consistent with the Board’s fiduciary obligations under the 1940 Act in connection with any annual review; however, in connection with such review of this Agreement by the Board, the Board acknowledges the fees to be received by PFPC Trust hereunder are fair and reasonable for a three-year term; or

(2) files a petition for bankruptcy, or another comparable filing by PFPC Trust has occurred; or

(3) has a materially impaired financial condition; or

(4) has a significant regulatory problem or is the subject of a significant regulatory investigation; and

in the case of subsections (1) through (4) above, the Board determines in the exercise of its fiduciary obligations under the 1940 Act that such event materially impairs PFPC Trust’s ability to perform its duties under this Agreement; or

(iv) by PFPC Trust, on one hundred fifty (150) days prior written notice, if the Fund is in material breach of the Agreement; and

(b) at any time after the first three years, without the payment of any penalty, on ninety (90) days prior written notice by the Fund or on one hundred fifty (150) days prior written notice by PFPC Trust.
