Dear Shareholder:

         On May 14, 2004, OMNI Energy Services Corp. (the "Company") sent to you
a proxy statement requesting your approval at the upcoming annual meeting of
shareholders of the Company on June 17, 2004 (the "Shareholders Meeting"), of,
among other things, certain Securities Purchase Agreements pursuant to which the
Company sold to certain investors securities in the form of convertible
debentures and warrants (the "Securities Purchase Agreements"). We have included
a copy of the proxy statement sent to you last month for your convenience. We
are in receipt of your proxy card for the proposals to be voted on at the
Shareholders Meeting; however, you have not cast a vote under Proposal No. 3
captioned "To approve the Securities Purchase Agreement". The Board of Directors
of the Company unanimously recommends that you vote FOR approval of the
Securities Purchase Agreements.

         Enclosed for your completion is a proxy card on which we urge you to
indicate your approval or disapproval under Proposal No. 3 captioned "To approve
the Securities Purchase Agreement". Note that any vote cast by a previously
submitted proxy will remain in effect unless you revoke your proxy or change
such vote in a subsequently submitted proxy. Thus, to vote on the Securities
Purchase Agreements proposal now, you only need to mark your vote under Proposal
No. 3 and return a signed and dated proxy - no vote on any other proposal is
necessary unless you wish to change your vote on such proposal.

         As noted above, the Shareholders Meeting will take place on June 17,
2004. Please return your proxy as soon as possible upon receipt so that your
vote may be counted at the Shareholders Meeting.

         PLEASE SIGN AND DATE THE ENCLOSED PROXY AND RETURN IT IN THE
ACCOMPANYING ENVELOPE AS PROMPTLY AS POSSIBLE. A PROXY MAY BE REVOKED AT ANY
TIME PRIOR TO THE VOTING THEREOF.



                                             By Order of the Board of Directors

                                             /s/ Staci L. Marcelissen
                                             STACI L. MARCELISSEN
