         "Funds"), and Investors Bank & Trust Company (the "Custodian") desire
         to amend the terms of the Master Custodian Agreement between the Funds
         and the Custodian as Amended and Restated on March 9, 1999 (the

                  NOW THEREFORE, in consideration of the premises and of the
         mutual convenants and agreements contained herein and in the Agreement,
         the parties hereby agree as follows:

1.                The Custodian shall, by no later than July 2, 2001, provide
                  the Fund or its investment adviser with an analysis of the
                  custody risks associated with maintaining assets with each
                  Securities Depository listed on Appendix B hereto in
                  accordance with Rule 17f-7(a)(1)(I)(A).

2.                In accordance with the requirements of Rule 17f-7, the
                  Custodian shall monitor the custody risks associated with
                  maintaining assets with each Securities Depository listed on
                  Appendix B hereto on a continuing basis, and shall promptly
                  notify the Fund or its investment advisor of any material
                  change in such risks.

3.                In carrying out its responsibilities under paragraphs 1 and 2
                  above, the Custodian agrees to exercise reasonable care,
                  prudence and diligence.

4.                The Custodian shall, concurrent with the execution of this
                  Agreement, provide each Fund or its investment adviser with
                  information which will enable such Fund or its investment
                  adviser to determine whether each Securities Depository listed
                  in Appendix B is an Eligible Securities Depository as defined
                  in Rule 27f-7(b)(1). The Custodian shall notify each Fund or
                  its investment adviser of any material change in any
                  information provided by the Custodian regarding whether a
                  Securities Depository meets the definition of Eligible
                  Securities Depository promptly after becoming aware of any
                  such change.



                  All capitalized terms not defined herein shall have the
         meaning provided in the Agreement.


         IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be
      executed as of the date first written above by their respective officers
      thereunto duly authorized.
