WITNESSETH:

THAT WHEREAS, the Customer represents that it is authorized to (a) open and maintain custody accounts (the “Custody Accounts”) with the Bank to hold certain property (“Property”) including, but not limited to, stocks, bonds, or other securities (“Securities”), funds and other property owned or held by the Customer, (b) enter into this Agreement, and (c) direct all actions and transactions contemplated hereunder. The Customer further represents that it is duly organized and in good standing under the laws of the state or country of its organization and the consummation of transactions contemplated hereby or directed by it hereunder will not violate any applicable laws, regulations or orders.

NOW, THEREFORE, in consideration of the premises and of the agreements hereinafter set forth, the parties hereby agree as follows:

1. APPOINTMENT AND ACCEPTANCE.

The Customer hereby appoints the Bank as custodian of the Property and as its agent hereunder, and the Bank agrees to act as such upon the terms and conditions hereinafter provided.

2. DELIVERY; SAFEKEEPING.

The Customer has heretofore delivered, or will deliver or cause to be delivered, Property to the Bank, which Property the Bank agrees to keep safely as custodian for the Customer. The Bank shall not surrender possession of Property except upon properly authorized Instructions (as hereinafter defined) of the Customer or as may be required by due process of applicable law.

3. IDENTIFICATION AND SEGREGATION OF ASSETS.

With respect to Property in the Custody Account:

(a) Except as otherwise provided in this Agreement, the Bank will separately identify on its books and segregate all Property held pursuant to this Agreement by the Bank or any other entity authorized to hold Property in accordance with Section 6 or 7 hereof. The Bank understands that the Customer is an open-end management investment company, registered with the SEC under the Investment Company Act of 1940 (“1940 Act”). The Customer issues several separate portfolios and the Customer’s Property, as well as its liabilities, are, and shall be, allocated to each such portfolio in accordance with the Customer’s instructions. “Portfolio”, as used herein, refers to the Customer’s Portfolio listed in Appendix X hereto, and any other separate Portfolio that may be created, from time to time, under the Customer’s Articles of Incorporation, and which become subject to this Agreement by the mutual consent of the Customer and the Bank. The Bank shall establish and maintain a separate Custody Account for each Portfolio and shall credit the Custody Account of each Portfolio with all Property received

by it for the account of such Portfolio and shall charge such account with the liabilities of such Portfolio. No Portfolio shall be charged with any liability of another Portfolio.

(b) The Bank shall supply to the Customer from time to time as mutually agreed upon a written statement with respect to all Property in the Custody Accounts. In the event that the Customer or its agent does not inform the Bank in writing of any exceptions or objections within ninety (90) days after the date of such statement, the Customer shall be deemed to have approved such statement with respect to the information contained therein but not with respect to any omission; provided, however, that if the Customer or its agent sends such written exception or objection more than ninety (90) days from the statement date, the Bank’s obligations to the Customer in regard to any transactions covered thereby shall be reduced to the extent that the Bank’s ability to mitigate any damages in connection with such transaction is compromised. Further, in no event shall the Bank be responsible after such 90 days for any subsequent increase in the fair market value of any Property or any interest with regard to any Property where the Customer reasonably should have informed the Bank of any exception or objection based on the information contained in any statement.

4. STANDARD OF CARE.

The Bank shall exercise the same standard of care that it exercises over its own assets in the safekeeping, handling, servicing and disposition of Property in accordance with this Agreement. The Bank will exercise the due care expected of a professional custodian for hire with respect to Property in its possession or control. Except as otherwise provided in this Agreement, the Bank shall not be responsible for any loss or damage suffered by the Customer unless such loss or damage results from an act of negligence or willful misconduct on the part of the Bank or on the part of (i) a branch, affiliate or subsidiary of the Bank acting as its agent or as a foreign custodian hereunder pursuant to the terms of this Agreement or (ii) any other foreign custodian appointed by the Bank pursuant to the terms of this Agreement; provided that, the liability of the Bank in connection with any Property shall not exceed the market value of the Property, to which such loss or damage relates, at the time such negligence or willful misconduct was discovered or should reasonably have been discovered, plus compensatory interest at prevailing rates. In no event shall the Bank be liable to the Customer for indirect, special or consequential damages.

In selecting and appointing U.S. depositories, foreign securities depositories and clearing agencies, the Bank shall exercise reasonable care, prudence and diligence. Subject to compliance with the obligations stated in the preceeding sentence, the Bank shall not be responsible for any loss or damage suffered by the Customer for any act or omission of a U.S. Depository, a foreign securities depository or clearing agent not caused by the act or omission of the Bank or its agent or a foreign custodian appointed by the Bank.

Any Property held by a foreign custodian or a foreign securities depository or clearing agency shall be subject to applicable laws, regulations, decrees, order, government acts, restrictions, customs, procedures and market practices (“Laws”) (i) to which such a foreign custodian or securities depository or clearing agency, is subject (ii) as exist in the country in which such Property is held and (iii) of the country of the currency in which the Property is denominated. In the event the Law change in a way that would prevent or limit the performance of duties and obligations by a foreign custodian or securities depository or clearing agency, such duties and obligations shall be superseded and neither the Bank nor its parent nor any other of its branches, subsidiaries or affiliates shall be liable therefor or for any damages in any way

resulting from such prevented or limited performance; provided, however, the Bank shall give prompt notice to the Customer of any such event.

Notwithstanding the above, neither (i) the Bank or its parent or any of its branches, subsidiaries nor affiliates nor (ii) the Customer is responsible for any losses or damages resulting from reasons or causes beyond its control, including, without limitation, nationalization, expropriation, currency restrictions, acts of war, terrorism, insurrection, revolution, civil unrest, riots or strikes, nuclear fusion or fission or acts of God.

The Bank is not under any duty to supervise the investments of the Customer, or to advise or make any recommendation to the Customer with respect to the purchase or sale of any Securities or the investment of any funds. The Customer shall have the sole and exclusive responsibility for the investment of Property held hereunder.

The Bank agrees to maintain insurance and fidelity bond coverage as appropriate for its activities located in New York City; provided, however, nothing in this Section 4 shall require the Bank to insure any Property.

5. PERFORMANCE BY THE BANK.

(f) Reports:

(i) If the Bank has in place a system for providing telecommunication access or other means of electronic access by customers to the Bank’s reporting system for Property in a Custody Account, then, at the Customer’s election, the Bank may agree to provide the Customer with such instructions and passwords as may be necessary in order for the Customer to have such direct access through the Customer’s terminal device. Such electronic access shall be restricted to information relating to the Custody Account. If electronic access to such reporting system is requested by the Customer, the Customer agrees to assume full responsibility for the consequences of the use, including any misuse or unauthorized use of the terminal device, instructions or passwords referred to above by the Customer or any of its employees or agents, but not for the unauthorized use resulting from negligent or wrongful acts of the Bank or its employees or agents, and agrees to defend and indemnify the Bank and hold the Bank harmless from and against any and all liabilities, losses, damages, costs, counsel fees, and other expenses of every nature suffered or incurred by the Bank by reason of, or in connection with, such use by the Customer or others of such terminal device, unless such liabilities, losses, damages, costs, counsel fees and other expenses can be shown to be the result of negligent or wrongful acts of the Bank.

provide the Customer on each business day a report of the preceding business day’s transactions relating to the Custody Account and of the closing or net balances of each business day.

Upon a reasonable request from the Customer, the Bank shall use its best efforts to furnish to the Customer such reports (or portions thereof) of the external auditors of each such entity as relate directly to such entity’s system of internal accounting controls applicable to its duties under its agreement with the Bank.
