Attn:       Vice President, Custody

Dear Sir or Madam:

                Lord Abbett Investment Trust (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 September 11, 2007 the Fund’s Board executed an Amendment to the Declaration and Agreement of Trust establishing a new Portfolio of the Fund, the legal name of which is as follows: Lord Abbett Floating Rate 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 Portfolio thereby making the Portfolio a Portfolio 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 December 14, 2007.

                It is currently anticipated that the registration statement for the Portfolio will become effective on December 14, 2007.  Accordingly, we appreciate your prompt attention to this matter.  Please indicate State Street’s acceptance by signing below.

Lord Abbett Investment Trust
