  Officer Regarding Facts and Circumstances Relating to Exchange Act Filings
  --------------------------------------------------------------------------

         I, Mayo A. Shattuck,III, Chairman of the Board, Chief Executive Officer
 and President of Constellation  Energy Group, Inc., state and attest that:

(1)      To the best of my knowledge, based upon a review of the covered reports
         of Constellation Energy Group, Inc., and, except as corrected or
         supplemented in a subsequent covered report:

         o    no covered report contained an untrue statement of a material fact
              as of the end of the period covered by such report (or in the case
              of a report on Form 8-K or definitive proxy materials, as of the
              date on which it was filed); and

         o    no covered report omitted to state a material fact necessary to
              make the statements in the covered report, in light of the
              circumstances under which they were made, not misleading as of the
              end of the period covered by such report (or in the case of a
              report on Form 8-K or definitive proxy materials, as of the date
              on which it was filed).

(2)      I have reviewed the contents of this statement with the audit committee
         of Constellation Energy Group, Inc.'s Board of Directors.

(3)      In this statement under oath, each of the following, if filed on or
         before the date of this statement, is a "covered report":

         o    Annual Report on Form 10-K for the fiscal year ended
              December 31, 2001 of Constellation Energy Group, Inc.;

         o    All reports on Form 10-Q, all reports on Form 8-K and all
              definitive proxy materials of Constellation Energy Group, Inc.
              filed with the Commission subsequent to the filing of the
              Form 10-K identified above; and

         o    Any amendments to any of the foregoing.
