Item 1.01 Entry into a Material Definitive Agreement.

         On October 12, 2004, OMNI Energy Services Corp. (the "Company")
announced that it has entered into an Amendment and Conditional Waiver Agreement
("Amendment") dated as of October 8, 2004, among the Company, Provident Premier
Master Fund Ltd., Portside Growth and Opportunity Fund, Manchester Securities
Corp., and Gemini Master Fund, Ltd. (each an "Investor" and collectively, the
"Investors").

         Pursuant to a Securities Purchase Agreement dated as of February 12,
2004 (the "First Securities Purchase Agreement"), the Company issued and sold to
the Investors named therein 6.5% Convertible Debentures (the "First Debentures")
and Warrants, and pursuant to a Securities Purchase Agreement dated as of April
15, 2004 (the "Second Securities Purchase Agreement" and together with the First
Securities Purchase Agreement the "Securities Purchase Agreements"), the Company
issued and sold to the Investors named therein 6.5% Convertible Debentures (the
"Second Debentures" and, collectively with the First Debentures, the
"Debentures") and Warrants.

         The Amendment amends, modifies, and waives certain terms and conditions
of the Securities Purchase Agreements and the Debentures.

         Pursuant to the Amendment, (i) the Investors will convert $2,000 of the
principal amount of the Second Debentures at a revised conversion price of $0.01
per share into 200,000 shares of the Company's common stock, (ii) the Investors
extended the date of the Company's October 1, 2004 interest payment under the
Debentures to October 18, 2004, (iii) the Investors extended the date of the
Company's October 7, 2004 payment of the Put Amount (as defined in the
Debentures) to October 18, 2004, and (iv) the Investors granted the Company a
right to redeem for cash all (but not less than all) of the outstanding
Debentures held by each Investor on or prior to 5 p.m., New York City time, on
November 15, 2004, for an aggregate redemption price equal to the then
outstanding principal of, and accrued and unpaid interest and penalties (if any)
on, the Debentures held by such Investor.

         The Amendment also permits the Company to obtain financing and incur
Debt (as defined in the Securities Purchase Agreements) senior to the Debentures
to fulfill its obligations under the Amendment if, simultaneously with the
closing of such financing, the Debentures are paid in full.

         The foregoing discussion is only a summary and is qualified in its
entirety by reference to the Amendment filed as Exhibit 4.1 hereto and
incorporated herein by reference.

         On October 12, 2004, the Company issued a press release announcing that
it had entered into the Amendment. A copy of the press release is furnished as
