                                 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 Blend Trust;

    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 officer 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 officer and I have disclosed to the
       Registrant's auditors and the audit committee of the Registrant's board
       of trustees (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 information; and

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