Attn: Vice President, Custody

Dear Sir or Madam:

Lord Abbett Municipal Income Fund, Inc. (the “Fund”), as a party to the Custodian and Investment Accounting Agreement between various Lord Abbett-sponsored mutual funds and State Street Bank and Trust Company (“State Street”) dated November 1, 2001 (the “Agreement”), requests an amendment to the Agreement pursuant to Section 17.

Section 17 of the Agreement provides that, “in the event that a Fund establishes one or more series with respect to which it desires to have State Street render services as custodian and recordkeeper under the terms [of the Agreement], it shall so notify State Street in writing, and if State Street agrees in writing to provide such services, such series of Shares shall become a Portfolio [under the terms of the Agreement].” This letter is to notify State Street that on July 26, 2010 the Fund’s Board executed Articles Supplementary to the Articles of Incorporation establishing a new Series of the Fund, the legal name of which is as follows: Lord Abbett AMT Free Municipal Bond Fund (the “Portfolio”). It is the Fund’s desire to have State Street render services as custodian and recordkeeper to the Portfolio under the terms of the Agreement; therefore, the Fund requests that State Street agree, in writing, to provide such services to the Series thereby making each Series a Series under the terms of the Agreement.

Attached is an Amended Exhibit A to the Agreement that shows the entity names and series of each fund that participates in the Agreement as of the close of business on October 26, 2010.

It is currently anticipated that the registration statement for the Portfolio will become effective on October 26, 2010. Accordingly, we appreciate your prompt attention to this matter. Please indicate State Street’s acceptance by signing below.

Lord Abbett Municipal Income Fund, Inc.
