ITEM 1.01. ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

         SECURITIES PURCHASE AGREEMENT

         On May 18, 2005, OMNI Energy Services Corp. (the "Company") announced
that it had entered into a Securities Purchase Agreement (the "Securities
Purchase Agreement") dated as of May 17, 2005, among the Company, The Dennis R.
Sciotto Family Trust Dated December 19, 1994, Edward E. Colson, III Family Trust
Dated January 2, 1995, Jimit Mehta, James C. Eckert and G. Darcy Klug
(collectively, the "Purchasers").

         Pursuant to the terms of the Securities Purchase Agreement, the Company
agreed to issue to the Purchasers (i) an aggregate of up to 5,000 shares of
Series C 9% Convertible Preferred Stock, no par value (the "Series C Preferred
Stock"), and (ii) warrants (the "Warrants") representing the right to purchase
up to an aggregate of 6,550,000 shares of the common stock of the Company, par
value $0.01 per share ("Common Stock"), for the exercise prices described
therein.

         The transactions contemplated by the Securities Purchase Agreement
close in two tranches. On May 17, 2005, the closing date of the first tranche,
the Company issued an aggregate of 3,500 shares of Series C Preferred Stock and
Warrants to acquire up to 4,585,000 shares of Common Stock, in exchange for
$3,500,000. Subject to the terms and conditions set forth in the Securities
Purchase Agreement, the second tranche is scheduled to close on August 15, 2005,
at which time the remainder of the Series C Preferred Stock and Warrants will be
issued.

         The Series C Preferred Stock is convertible into shares of Common Stock
at an initial conversion price of $1.95 per share. The 5,000 shares of Series C
Preferred Stock converts into approximately 2,564,103 shares of Common Stock.
Cumulative dividends will accrue on the Series C Preferred Stock at 9% per annum
and will be payable in equal quarterly installments. Beginning on May 17, 2009,
the Company will have the right to redeem the shares of Series C Preferred
Stock, in whole or in part, at a price equal to $1,000 per share plus an amount
equal to all dividends (whether or not declared or due) accrued and unpaid on
each such share up to the date of the redemption, subject to the Purchaser's
right to convert the Series C Preferred Stock into Common Stock.

         The Warrants issued in the first tranche, which together are estimated
to be exercisable into 4,585,000 shares of Common Stock, will be issued as
follows: (i) 3,360,000 five-year warrants exercisable at a price per share of
$1.95 (the "Series A Warrants"); (ii) 875,000 five-year warrants exercisable at
a price per share of $2.50 (the "Series B Warrants"); and (iii) 350,000
five-year warrants exercisable at a price per share of $3.50 (the "Series C
Warrants").

         The foregoing discussion is only a summary and is qualified in its
entirety by reference to the Securities Purchase Agreement, the Warrants, the
Articles of Amendment to the Articles of Incorporation of the Company filed by
the Company in connection with the foregoing transactions (the "Articles of
Amendment"), the Registration Rights Agreement and the press release filed as
exhibits hereto and incorporated herein by reference.

         CREDIT FACILITIES

         On May 18, 2005, the Company announced it had completed $65 million of
senior credit facilities (the "Senior Credit Facilities") with a syndicate of
lenders including General Electric Capital Corporation and Webster Business
Credit Corporation. The proceeds will be used to re-finance certain long-term
debt and provide working capital.

         The Senior Credit Facilities include a $50 million equipment Term A
Loan and a $15 million working capital revolver. Borrowing under the asset based
Term A Loan is determined by advance rates on the agreed upon value of the
Company's unencumbered aviation, seismic drilling and environmental equipment.
The Term A Loan matures in 60 months, with level amortization over 120 months.
Principal



payments will be made quarterly, with interest accruing at an initial rate of
30-day LIBOR plus 6.5%, also payable quarterly, in arrears.

         The Company also announced that it has increased its working capital
revolver (the "Revolver") with Webster Business Credit Corporation to $15
million from $12 million, pursuant to the Amended and Restated Credit and
Security Agreement (the "Revolver Agreement"). Availability under the Revolver
is based upon the Company's level of eligible accounts receivable and
inventories of spare parts. The Revolver matures in 60 months and will initially
accrue interest at a rate of prime plus 2.5%, or at the Company's option, LIBOR
plus 5%, payable monthly in arrears.

         The foregoing discussion is only a summary and is qualified in its
entirety by reference to the Credit Agreement and the Revolver Agreement, copies
of which are attached as exhibits hereto and incorporated herein by reference.

         SETTLEMENT AGREEMENTS

         On May 18, 2005, the Company announced that it had entered into
settlement agreements (the "Settlement Agreements") with all of the holders of
its 6.5% Subordinated Convertible Debentures (the "Debenture Holders"). The
Settlement Agreements provide for (i) the payment to the Debenture Holders of
approximately $4.0 million in cash, (ii) the issuance of 2 million shares of
Common Stock to the Debenture Holders; and (iii) the issuance of approximately
$4.3 million of 8% subordinated notes, payable over 3 years, to the Debenture
Holders. The Company has also agreed to register the 2 million shares of Common
Stock under a new Registration Rights Agreement with each of the Debenture
Holders, copies of which are attached as exhibits hereto. Pursuant to the terms
of the Settlement Agreements, in exchange for the full and complete
extinguishment of the Debentures and the release of all claims against the
Company, the Company has agreed to dismiss the Debenture Holders from certain
litigation recently filed by the Company against the Debenture Holders alleging
violations of Section 16(b) of the Securities Exchange Act of 1934, among other
things.

         The foregoing discussion is only a summary and is qualified in its
entirety by reference to the Settlement Agreements and the Registration Rights
Agreements referenced in the preceding paragraph, copies of which are attached
as exhibits hereto and incorporated herein by reference.

         SURRENDER OF NOTE AGREEMENT

         On May 18, 2005, the Company announced that it had entered into a
Surrender of Note Agreement dated May 18, 2005 (the "Surrender of Note
Agreement") with certain of its subordinated debt holders. The Surrender of Note
Agreement revises the payment terms of $2 million of $3 million in outstanding
subordinated debt issued in connection with the Company's June 2004 acquisition
of Trussco, Inc. In addition, the Surrender of Note Agreement cancels $1 million
of a $3 million earnout note also issued in connection with the Trussco, Inc.
acquisition (the "Earnout Note").

         Under the terms of the Surrender of Note Agreement, OMNI will pay to
the holders of the subordinated debt, $1 million cash on or before August 16,
2005, and will issue the subordinated debt holders 200,000 shares of Common
Stock in full and complete satisfaction of $2 million of subordinated debt and
cancellation of $1 million of the Earnout Note. The terms of the balance of the
$1 million of the subordinated debentures and $2 million of the Earnout Note
will remain unchanged.

ITEM 1.02. TERMINATION OF MATERIAL DEFINITIVE AGREEMENTS

         The $6.5 million Promissory Note dated October, 22, 2005 payable to
Beal Bank, SSB, issued by the Company and four of its wholly-owned subsidiaries
has been paid in full and the related security agreement, of even date
therewith, terminated.

         The Credit and Security Agreement by and among the Company and two of
its subsidiaries, as borrowers, and Whitehall Business Credit Corporation, as
lender, dated December 23, 2003, was



superseded by the Amended and Restated Credit and Security Agreement, a copy of
which is attached hereto and incorporated herein by reference.

ITEM 2.03. CREATION OF A DIRECT FINANCIAL OBLIGATION OR AN OBLIGATION UNDER AN

to these securities as soon as reasonably practicable.

         The information disclosed in Item 1.01 of this Current Report on Form

ITEM 3.03. MATERIAL MODIFICATION OF RIGHTS OF SECURITY HOLDERS

         On May 17, 2005, the Company filed the Articles of Amendment with the
Louisiana Secretary of State. The Articles of Amendment define the rights of the
Series C Preferred Stock. Pursuant to the Articles of Amendment, the shares of
the Series C Preferred Stock to be issued pursuant to the Securities Purchase
Agreement have certain rights as to conversion, liquidation and adjustment to
conversion price; provided, however, that, until the shareholders of the Company
approve the transaction, in no event may a holder of Series C Preferred Stock be
entitled to convert shares of Series C Preferred Stock if after such conversion
the holder will hold more than 19.99% of the outstanding Common Stock or voting
power of the Company on the date of such conversion.

         The foregoing description of the Articles of Amendment and the
transactions contemplated thereby do not purport to be complete and are
qualified in their entirety reference to the Articles of Amendment, a copy of
which is filed as an exhibit hereto and is hereby incorporated herein by
reference.
