Exhibit 8(a)


                                   AMENDMENT
                                    TO THE
                TRANSFER AGENCY, DIVIDEND DISBURSING AGENCY AND
                    SHAREHOLDER SERVICING AGENCY AGREEMENT

     WHEREAS, Financial Data Services, Inc. ("FDS") and Merrill Lynch Low
Duration Fund, Inc. (the "Fund"), on behalf of itself and certain of its
series, entered into a Transfer Agency, Dividend Disbursing Agency and
Shareholder Servicing Agency Agreement, as amended (the "Agreement");

     WHEREAS, the parties hereto desire to amend the Agreement to reflect the
Fund's issuance of Class R shares; and

     WHEREAS, the parties hereto desire to amend the Agreement to reflect
services FDS may provide to the Fund in connection with the Fund's money
laundering prevention programs and compensation to FDS for such services.

     NOW, THEREFORE, FDS and the Fund hereby amend the Agreement as follows:

1.   The parties agree that, in order to more accurately reflect the conduct
     of their business relationship, Paragraph 3(t) of the Agreement shall be
     re-designated Paragraph 3(g) and a new Paragraph 3(t) added to read in
     its entirety: "FDS agrees to perform such anti-money laundering ("AML")
     functions with respect to the Fund's shares as the Fund or its agent may
     delegate to FDS from time to time or as IDS is otherwise obligated to
     perform. In accordance with mutually-agreed procedures, FDS shall use its
     best efforts in carrying out such functions under the Fund's AML program.
     Fund shareholders (which for this purpose shall mean only shareholders of
     record) are customers of the Fund and not customers of IDS and the Fund
     retains legal responsibility under the USA PATRIOT Act for AML compliance
     with respect to transactions in Fund shares." FDS agrees to cooperate
     with any request from examiners of US Government agencies having
     jurisdiction over the Fund for information and records relating to the
     Fund's AML program and E consents to inspection by such examiners for
     this purpose.

2.   The parties agree that the compensation payable in connection with
     certain accounts will be modified. Pursuant to Section 4 of the
     Agreement, the compensation payable to FDS on services for such accounts
     is set forth in the Amended and Restated Schedule of Fees attached to
     this Amendment, which shall become a part of the Agreement and shall be
     effective as of January 1, 2003.

     IN WITNESS HEREOF, the parties hereto have executed this Amendment as of
this 1st day of January, 2003.
