                                 CERTIFICATIONS

                         Pursuant to Section 302 of the
                           Sarbanes-Oxley Act of 2002

I, Robert S. Dow, certify that:

   1. I have reviewed this report on Form N-CSR of Lord Abbett U.S. Government &
      Government Sponsored Enterprises Money Market Fund, Inc.

   2. Based on my knowledge, this report does not contain any untrue statements
      of material fact or omit to state a material fact necessary to make the
      statements made, in light of the circumstances under which such statements
      were made, not misleading with respect to the period covered by this
      report;

   3. Based on my knowledge, the financial statements, and other financial
      information included in this report, fairly present in all material
      respects the financial condition, results of operations, changes in net
      assets, and cash flows (if the financial statements are required to
      include a statement of cash flows) of the Registrant as of, and for, the
      periods presented in this report;

   4. The Registrant's other certifying officers and I are responsible for
      establishing and maintaining disclosure controls and procedures (as
      defined in Rule 30a-3(c) under the Investment Company Act of 1940) for the
      Registrant and have:

         a. designed such disclosure controls and procedures, or caused such
            disclosure controls and procedures to be designed under our
            supervision, to ensure that material information relating to the
            Registrant, including its consolidated subsidiaries, is made known
            to us by others within those entities, particularly during the
            period in which this report is being prepared; and

         b. evaluated the effectiveness of the Registrant's disclosure controls
            and procedures and presented in this report our conclusions about
            the effectiveness of the disclosure controls and procedures, as of a
            date within 90 days prior to the filing date of this report based on
            such evaluation;

   5. The Registrant's other certifying officers and I have disclosed, based on
      our most recent evaluation, to the Registrant's auditors and the audit
      committee or the Registrant's Board of Directors (or persons performing
      the equivalent functions):

<Page>

         a. all significant deficiencies and material weaknesses in the design
            or operation of internal control over financial reporting which are
            reasonably likely to adversely affect the Registrant's ability to
            record, process, summarize, and report financial data; and

         b. any fraud, whether or not material, that involves management or
            other employees who have a significant role in the Registrant's
            internal controls over financial reporting; and

   6. The Registrant's other certifying officers and I have indicated in this
      report whether or not there were significant changes in internal controls
      or in other factors that could significantly affect internal controls
      subsequent to the date of our most recent evaluation, including any
      corrective actions with regard to significant deficiencies and material
      weaknesses.
