contractual payment date if the Custodian reasonably believes that such amount
will not be received.

c. CONTRACTUAL SETTLEMENT. The Custodian will attend to the settlement of
securities transactions in accordance with the Custodian's standard operating
procedure, on the basis of either contractual settlement date accounting or
actual settlement date accounting. To the extent the Custodian settles certain
securities transactions on the basis of contractual settlement date accounting,
the Custodian may reverse to the contractual settlement date any entry relating
to such contractual settlement if the Custodian reasonably believes that such
amount will not be received.

4. LENDING OF SECURITIES. The Custodian may lend the assets of the Series in
accordance with the terms and conditions of a separate securities lending
agreement, approved by the Fund.

5. PERSONS HAVING ACCESS TO ASSETS OF THE SERIES.

Fund, or of the Fund's administrator, shall have physical access to the assets
of the Series held by the Custodian or be authorized or permitted to withdraw
any investments of the Series, nor shall the Custodian deliver any assets of the

with any sub-investment adviser of the Fund or with the Fund's administrator
shall have access to the assets of the Series.

b. Nothing in this Section 5 shall prohibit any duly authorized officer,
employee or agent of the Fund, or any duly authorized officer, director,
employee or agent of the investment adviser, of any sub-investment adviser of
the Series or of the Series' administrator, from giving Instructions to the
Custodian or executing a Certificate so long as it does not result in delivery
of or access to assets of the Series prohibited by paragraph (a) of this Section
5.

6. STANDARD OF CARE; SCOPE OF CUSTODIAL RESPONSIBILITIES.

a. STANDARD OF CARE. Custodian shall be required to exercise reasonable
care with respect to its duties under this Agreement unless otherwise provided.

(1) Notwithstanding any other provision of this Custody Agreement, the
Custodian shall not be liable for any loss or damage, including counsel fees,
resulting from its action or omission to act or otherwise, except for any such
loss or damage arising out of the negligence or willful misconduct of the
Custodian.

(2) The Custodian may, with respect to questions of law, apply for and
obtain the advice and opinion of counsel to the Fund or of its own counsel, at
the expense of the Fund, and shall be fully protected with respect to anything
done or omitted by it in good faith in conformity with such advice or opinion.

b. SCOPE OF DUTIES. Without limiting the generality of the foregoing, the
Custodian shall be under no duty or obligation to inquire into, and shall not be
liable for:

(1) The acts or omissions of any agent appointed pursuant to
Instructions of the Fund or its investment advisor including, but not limited
to, any broker-dealer or other entity to hold any Securities or other property
of the Fund as collateral or otherwise pursuant to any investment strategy.

(2) The validity of the issue of any Securities purchased by the Series,
the legality of the purchase thereof, or the propriety of the amount paid
therefor;

propriety of the amount for which the same are sold;

(4) The legality of the issue or sale of any Shares, or the sufficiency
of the amount to be received therefor;

the amount to be paid therefore

(6) The legality of the declaration or payment of any distribution of
the Series;

(7) The legality of any borrowing for temporary administrative or

c. NO LIABILITY UNTIL RECEIPT. The Custodian shall not be liable for, or
considered to be the Custodian of, any money, whether or not represented by any
check, draft, or other instrument for the payment of money, received by it on
behalf of the Series until the Custodian actually receives and collects such
money.

d. AMOUNTS DUE FROM TRANSFER AGENT. The Custodian shall not be required

to effect collection of any amount due to the Series from the Series' transfer
agent nor be required to cause payment or distribution by such transfer agent of
any amount paid by the Custodian to the transfer agent.

e. COLLECTION WHERE PAYMENT REFUSED. The Custodian shall not be required to
take action to effect collection of any amount, if the Securities upon which
such amount is payable are in default, or if payment is refused after due demand
or presentation, unless and until it shall be directed to take such action and
it shall be assured to its satisfaction of reimbursement of its related costs
and expenses.

f. NO DUTY TO ASCERTAIN AUTHORITY. The Custodian shall not be under any
duty or obligation to ascertain whether any Securities at any time delivered to
or held by it for the Series are such as may properly be held by the Series
under the provisions of its governing instruments or Prospectus.

g. RELIANCE ON INSTRUCTIONS. The Custodian shall be entitled to rely upon
any Instruction, notice or other instrument in writing received by the Custodian
and reasonably believed by the Custodian to be genuine and to be signed by an
officer or Authorized Person of the Series. Where the Custodian is issued
Instructions orally, the Series acknowledge that if written confirmation is
requested, the validity of the transactions or enforceability of the
transactions authorized by the Series shall not be affected if such confirmation
is not received or is contrary to oral Instructions given. The Custodian shall
be fully protected in acting in accordance with all such Instructions and in
failing to act in the absence thereof. The Custodian shall be under no duty to
question any direction of an Authorized Person with respect to the portion of
the account over which such Authorized Person has authority, to review any
property held in the account, to make any suggestions with respect to the
investment and reinvestment of the assets in the account, or to evaluate or
question the performance of any Authorized Person. The Custodian shall not be
responsible or liable for any diminution of value of any securities or other
property held by the Custodian or its subcustodians pursuant to Instructions. In
following Instructions, the Custodian shall be fully protected and shall not be
liable for the acts or omissions of any person or entity not selected or
retained by the Custodian in its sole discretion, including but not limited to,
any broker-dealer or other entity designed by the Fund or Authorized Person to
hold property of the account as collateral or otherwise pursuant to an
investment strategy.

7. APPOINTMENT OF SUBCUSTODIANS. The Custodian is hereby authorized to appoint
one or more domestic subcustodians (which may be an affiliate of the Custodian)
to hold Securities and monies at any time owned by the Series. The Custodian is
also hereby authorized when acting pursuant to Instructions to: 1) place assets
with any Foreign Custodian located in a jurisdiction which is not a Selected
Country and with Euroclear, Clearstream, Banc One or any other transnational
depository; and 2) place assets with a broker or other agent as subcustodian in
connection with futures, options, short selling or other transactions. When
acting pursuant to such Instructions, the Custodian shall not be liable for the
acts or omissions of any subcustodian so appointed.

8. OVERDRAFT FACILITY AND SECURITY FOR PAYMENT. In the event that the Custodian
receives Instructions to make payments or transfers of monies on behalf of the
Series for which there would be, at the close of business on the date of such
payment or transfer, insufficient monies held by the Custodian on behalf of the
Series, the Custodian may, in its sole discretion, provide an overdraft (an
"Overdraft") to the Series in an amount sufficient to allow the completion of
such payment or transfer. Any Overdraft provided hereunder: (a) shall be payable
on the next Business Day, unless otherwise agreed by the Series and the
Custodian; and (b) shall accrue interest from the date of the Overdraft to the
date of payment in full by the Series at a rate agreed upon from time to time by
the Custodian and the Series or, in the absence of specific agreement, by such
rate as charged to other customers of Custodian under procedures uniformly
applied. The Custodian and the Series acknowledge that the purpose of such
Overdraft is to temporarily finance the purchase of Securities for prompt
delivery in accordance with the terms hereof, to meet unanticipated or unusual
redemptions, to allow the settlement of foreign exchange contracts or to meet
other unanticipated Series expenses. The Custodian shall promptly notify the
Series (an "Overdraft Notice") of any Overdraft. To secure payment of any
Overdraft and related interest and expenses, the Series hereby grants to the
Custodian a first priority security interest in and right of setoff against the
Securities and cash in the Series' account, including all income, substitutions
and proceeds, whether now owned or hereafter acquired (the "Collateral"), in the
full amount of such Overdraft, interest and expenses; provided that the Series
does not grant the Custodian a security interest in any Securities issued by an
affiliate of the Custodian (as defined in Section 23A of the Federal Reserve
Act). The Custodian and the Series intend that, as the securities intermediary
with respect to the Collateral, the Custodian's security interest shall
automatically be perfected when it attaches. Should the Series fail to pay
promptly any amounts owed hereunder, the Custodian shall be entitled to use
available cash in the Series' account and to liquidate Securities in the account
as necessary to meet the Series' obligations relating to such Overdraft,
interest and expenses. In any such case, and without limiting the foregoing, the
Custodian shall be entitled to take such other actions(s) or exercise such other
options, powers and rights as the Custodian now or hereafter has as a secured
creditor under the Massachusetts Uniform Commercial Code or any other applicable
law.

9. TAX OBLIGATIONS. For purposes of this Agreement, "Tax Obligations" shall
mean taxes, withholding, certification and reporting requirements, claims for
exemptions or refund, interest, penalties, additions to tax and other related
expenses. To the extent that the Custodian has received relevant and necessary
information with respect to the account, the Custodian shall perform the
following services with respect to Tax Obligations:

a. The Custodian shall file claims for exemptions or refunds with respect
to withheld foreign (non-U.S.) taxes in instances in which such claims are
appropriate;

b. The Custodian shall withhold appropriate amounts, as required by U.S.
tax laws, with respect to amounts received on behalf of nonresident aliens; and

c. The Custodian shall provide to the Fund or the Authorized Person such

information received by the Custodian which could, in the Custodian's reasonable
belief, assist the Fund or the Authorized Person in the submission of any
reports or returns with respect to Tax Obligations. The Fund shall inform the
Custodian in writing as to which party or parties shall receive information from
the Custodian.

The Custodian shall provide such other services with respect to Tax
Obligations, including preparation and filing of tax returns and reports and
payment of amounts due (to the extent funded), as requested by the Fund and
agreed to by the Custodian in writing. The Custodian shall have no independent
obligation to determine the existence of any information with respect to, or the
extent of, any Tax Obligations now or hereafter imposed on the Fund or the
account by any taxing authority. Except as specifically provided herein or
agreed to in writing by the Custodian, the Custodian shall have no obligations
or liability with respect to Tax Obligations, including, without limitation, any
obligation to file or submit returns or reports with any taxing authorities.

In making payments to service providers pursuant to Instructions, the
Fund acknowledges that the Custodian is acting as a paying agent and not as the
payor, for tax information reporting and withholding purposes.

ARTICLE II. - FOREIGN CUSTODY MANAGER SERVICES

1. DELEGATION. The Board delegates to, and the Custodian hereby agrees to
accept responsibility as the Fund's Foreign Custody Manager for selecting,
contracting with and monitoring Foreign Custodians in Selected Countries set
forth in Appendix C in accordance with Rule 17f-5(c).

2. CHANGES TO APPENDIX C. Appendix C may be amended by written agreement from
time to time to add or delete jurisdictions by written agreement signed by an
Authorized Person of the Fund and the Custodian, but the Custodian reserves the
right to delete jurisdictions upon reasonable notice to the Series.

3. REPORTS TO BOARD. Custodian shall provide written reports notifying the
Board of the placement of Assets with a particular Foreign Custodian and of any

the Fund.

delegated authority to place Assets with a Foreign Custodian, the Custodian
shall establish a system, to re-assess or re-evaluate selected Foreign
Custodians, at least annually in accordance with Rule 17f-5(c)(3).

5. STANDARD OF CARE. In exercising the delegated authority under this Article
II of the Agreement, the Custodian agrees to exercise reasonable care, prudence
and diligence such as a person having responsibility for the safekeeping of the
Assets would exercise in like circumstances. Contracts with Foreign Custodians
shall provide for reasonable care for Assets based on the standards applicable
to Foreign Custodians in the Selected

Country. In making this determination, the Custodian shall consider the
provisions of Rule 17f-5(c)(2).

6. USE OF SECURITIES DEPOSITORIES. In exercising its delegated authority, the
Custodian may assume that the Series and its investment adviser have determined,
pursuant to Rule 17f-7, that the depository provides reasonable safeguards
against custody risks, if a Series decides to place and maintain foreign assets
with any Securities Depository as to which the Custodian has provided the Fund
on behalf of such Series with a Risk Analysis.

ARTICLE III. - INFORMATION SERVICES

1. RISK ANALYSIS. The Custodian will provide the Fund on behalf of the Series
with a Risk Analysis with respect to Securities Depositories operating in the
countries listed in Appendix C. If the Custodian is unable to provide a Risk
Analysis with respect to a particular Securities Depository, it will notify the
Fund on behalf of the Series. If a new Securities Depository commences operation
in one of the Appendix C countries, the Custodian will provide the Fund on
behalf of the Series with a Risk Analysis in a reasonably practicable time after
such Securities Depository becomes operational. If a new country is added to
Appendix C, the Custodian will provide the Fund on behalf of the Series with a
Risk Analysis with respect to each Securities Depository in that country within
a reasonably practicable time after the addition of the country to Appendix C.

2. MONITORING OF SECURITIES DEPOSITORIES. The Custodian will monitor the
custody risks associated with maintaining assets with each Securities Depository
for which it has provided the Fund on behalf of the Series with a Risk Analysis
as required under Rule 17f-7. The Custodian will promptly notify the Fund on
behalf of the Series or its investment adviser of any material change in these
risks.

3. USE OF AGENTS. The Custodian may employ agents, including, but not limited
to Foreign Custodians, to perform its responsibilities under Sections 1 and 2
above.

4. EXERCISE OF REASONABLE CARE The Custodian will exercise reasonable care,
prudence, and diligence in performing its responsibilities under this Article
III. With respect to the Risk Analyses provided or monitoring performed by an
agent, the Custodian will exercise reasonable care in the selection of such
agent, and shall be entitled to rely upon information provided by agents so
selected in the performance of its duties and responsibilities under this
Article III.

5. LIABILITIES AND WARRANTIES. While the Custodian will take reasonable
precautions to ensure that information provided is accurate, the Custodian shall
have no liability with respect to information provided to it by third parties.
Due to the nature and source of information, and the necessity of relying on
various information sources, most of which are external to the Custodian, the
Custodian shall have no liability for direct or indirect use of such
information.

ARTICLE IV. - GENERAL PROVISIONS

1. COMPENSATION.

a. The Fund will compensate the Custodian for its services rendered under
this Agreement in accordance with the fees set forth in a separate Fee Schedule
which schedule may be modified by the Custodian upon not less than sixty days
prior written notice to the Fund.

b. The Custodian will ▇▇▇▇ the Fund as soon as practicable after the end of
each calendar month. The Fund will promptly pay to the Custodian the amount of
such billing.

c. If not paid directly or timely by the Fund, the Custodian may charge
against assets held on behalf of the Series compensation and any expenses
incurred by the Custodian in the performance of its duties pursuant to this
Agreement. The Custodian shall also be entitled to charge against assets of the
Series the amount of any loss, damage, liability or expense incurred with
respect to the Series, including counsel fees, for which it shall be entitled to
reimbursement under the provisions of this Agreement. The expenses which the
Custodian may charge include, but are not limited to, the expenses of domestic
subcustodians and Foreign Custodians incurred in settling transactions.

2. INSOLVENCY OF FOREIGN CUSTODIANS. The Custodian shall be responsible for
losses or damages suffered by the Series arising as a result of the insolvency
of a Foreign Custodian only to the extent that the Custodian failed to comply
with the standard of care set forth in Article II with respect to the selection
and monitoring of such Foreign Custodian.

3. LIABILITY FOR DEPOSITORIES. The Custodian shall not be responsible for any
losses resulting from the deposit or maintenance of Securities, Assets or other
property of the Series with a Securities Depository.

4. DAMAGES. Under no circumstances shall the Custodian be liable for any
indirect, consequential or special damages with respect to its role as Foreign
Custody Manager, Custodian or information vendor.

5. INDEMNIFICATION; LIABILITY OF THE SERIES.

a. The Fund shall indemnify and hold the Custodian harmless from all
liability and costs, including reasonable counsel fees and expenses, relating to
or arising out of the performance of the Custodian's obligations under this
Agreement except to the extent resulting from the Custodian's negligence or
willful misconduct. This provision shall survive the termination of this
Agreement.

b. The Series and the Custodian agree that the obligations of the Fund
under this Agreement shall not be binding upon any of the trustees,
shareholders, nominees,

officers, employees or agents, whether past, present or future, of the Series,
individually, but are binding only upon the assets and property of the Fund.

6. FORCE MAJEURE. Notwithstanding anything in this Agreement to the contrary
contained herein, the Custodian shall not be responsible or liable for its
failure to perform under this Agreement or for any losses to the account
resulting from any event beyond the reasonable control of the Custodian, its
agents or subcustodians. This provision shall survive the termination of this
Agreement

7. TERMINATION.

a. Either party may terminate this Agreement by giving the other party
sixty (60) days notice in writing, specifying the date of such termination. In
the event notice is given by the Fund, it shall be accompanied by a Certificate
evidencing the vote of the Fund's Board to terminate this Agreement and
designating a successor.

b. In the event notice of termination is given by the Custodian, the Fund
shall, on or before the termination date, deliver to the Custodian a Certificate
evidencing the vote of the Board designating a successor custodian. In the
absence of such designation, the Custodian may designate a successor custodian,
which shall be a person qualified to so act under the Act or the Series. If the
Fund fails to designate a successor custodian, the Fund shall, upon the date
specified in the notice of termination, and upon the delivery by the Custodian
of all Securities and monies then owned by the Series, be deemed to be its own
custodian and the Custodian shall thereby be relieved of all duties and or the
Series responsibilities under this Agreement other than the duty with respect to
Securities held in the Book-Entry System which cannot be delivered to the
Series.

c. Upon termination of the Agreement, the Custodian shall, upon receipt of
a notice of acceptance by the successor custodian, deliver to the successor all
Securities and monies then held by the Custodian on behalf of the Series, after
deducting all fees, expenses and other amounts owed.

d. In the event of a dispute following the termination of this Agreement,
all relevant provisions shall be deemed to continue to apply to the obligations
and liabilities of the parties.

8. INSPECTION OF BOOKS AND RECORDS. The books and records of the Custodian
directly related to the Fund shall be open to inspection and audit at reasonable
times by officers and auditors employed by the Fund at its own expense and with
prior written notice to the Custodian, and by the appropriate employees of the
Securities and Exchange Commission.
