AUDIT COMMITTEE

         Under rules adopted by the SEC, the Company is required to disclose
whether it has an "Audit Committee Financial Expert" serving on its Audit
Committee. Although management believes that at least one member of the Audit
Committee would qualify as an Audit Committee Financial Expert, the Company's
Board of Directors has not designated any particular member of the Audit
Committee as the Audit Committee Financial Expert under the SEC's rules.
Management believes that at least one member of the Audit Committee is capable
of: (i) understanding generally accepted accounting principles and financial
statements; (ii) assessing the general application of these principles in
connection with the accounting for estimates, accruals and reserves; (iii)
analyzing and evaluating the Company's consolidated financial statements; (iv)
understanding internal control over financial reporting; and (v) understanding
audit committee functions. All Audit Committee members are "independent
directors," as such term is defined in NASD's Rule 4200 (a) (15).

         The responsibilities of our audit committee include:

                  -        engaging an independent audit firm to audit our
                           financial statements and to perform services related
                           to the audit;

                  -        reviewing the scope and results of the audit with our
                           independent auditors;

                  -        considering the adequacy of our internal accounting
                           control procedures;

                  -        considering auditors' independence; and

                  -        approving all audit and non-audit services with our
                           independent auditors.

         The board of directors has adopted a written charter for the audit
committee. The audit committee held four meetings during fiscal year 2003.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

         None of the members of the Compensation Committee has at any time been
an officer or employee of the Company and none of these directors serve as a
member of the board of directors or compensation committee of any entity that
has one or more executive officers serving as a member of the Company's board or
Compensation Committee.

COMPENSATION OF DIRECTORS

         Each non-employee director is paid an attendance fee of $6,250 for each
Board meeting attended and $1,500 for each committee meeting attended. Committee
Chairmen are now paid $2,500 for each committee meeting. All directors are
reimbursed for reasonable out-of-pocket expenses incurred in attending Board and
committee meetings.

         Each person who becomes a non-employee director is granted an option to
purchase 5,000 shares of Common Stock at an exercise price equal to the fair
market value of the Common Stock on the date such person becomes a director.

         Additionally, each year that the Company's Stock Incentive Plan is in
effect and a sufficient number of shares of Common Stock are available
thereunder, each person who is a non-employee director on the day following the
annual meeting of the Company's stockholders will be granted an option to
purchase 10,000 shares of Common Stock at an exercise price equal to the fair
market value of the Common Stock on such date. All such options become fully
exercisable on the first anniversary of their date of grant and expire on the
tenth anniversary thereof, unless the non-employee director ceases to be a
director of the Company, in which case the exercise periods will be shortened.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.

         The Series A Preferred Stock has an 8% cumulative dividend rate, is
convertible into our common stock with a conversion rate of $2.25, is redeemable
at our option at $1,000 per share plus accrued dividends, contains a liquidation
preference of $1,000 per share plus accrued dividends, has voting rights on all
matters submitted to a vote of our stockholders, has separate voting rights with
respect to matters that would affect the rights of the holders of the Preferred
Stock, and has aggregate voting rights of the affiliate limited to 49% of our
total outstanding common and preferred shares with voting rights. In respect to
the Series A Preferred Stock, the affiliate has agreed to waive its conversion
rights until our EBITDA (as defined) reaches a mutually agreed upon level.
Pursuant to an agreement with the preferred stockholders, dividends did not
accrue on the outstanding stock from April 2001 through June 2002. Dividends
were accreted at 8% during the free dividend period. As of September 2003, there
were approximately $0.3 million dividends in arrears relating to these
outstanding shares of Series A Preferred Stock. The affiliate previously agreed
that dividends would not accrue after June 30, 2002, until our EBITDA reached a
mutually agreed upon level. During the third quarter of 2003, we agreed with the
holders of the preferred stock that our EBITDA had reached an acceptable level
for the resumption of conversion rights and the accrual of dividends. Pursuant
to our senior secured credit agreements, the dividends will be paid "in kind"
(in shares of like preferred stock) rather than in cash. At December 31, 2003,
we had a total of 7,500 shares of Series A Preferred Stock outstanding.

                                       7
<PAGE>

Subsequent to December 31, 2003, we issued $10 million of 6.5% Subordinated
Convertible Debentures. The proceeds were used to redeem $8.2 million of the
Series A Preferred Stock, including accrued dividends paid in cash.

         In May 2001, we committed to issue 4,600 shares of Series B Preferred
Stock to an affiliate of ours in satisfaction of all outstanding principal and
interest owed under the subordinated debt agreements (See Note 3). These shares
were issued in March 2002. The Series B Preferred Stock has an 8% cumulative
dividend rate, is convertible into our common stock with an initial conversion
rate of $3.75, is redeemable at our option at $1,000 per share plus accrued
dividends, contains a liquidation preference of $1,000 per share plus accrued
dividends and has no voting rights until such time as it becomes convertible.
The Series B Preferred Stock does not have conversion rights until our EBITDA
(as defined) reaches a mutually agreed upon level, and until all shares of
Series A Preferred Stock become convertible. Pursuant to an agreement with the
preferred stockholders, dividends did not accrue on the outstanding stock from
April 2001 through June 2002. Dividends were accreted at 8% during the free
dividend period. The affiliate previously agreed that dividends would not accrue
after June 30, 2002 until our EBITDA reached a mutually agreed upon level.
During the third quarter of 2003 we agreed with the holders of the preferred
stock that our EBITDA had reached an acceptable level for the resumption of
conversion rights and the accrual of dividends. Pursuant to our senior secured
credit agreements, the dividends will be paid "in kind" (in shares of like
preferred stock) rather than in cash. At December 31, 2003, we had a total of
4,600 shares of Series B Preferred Stock outstanding. Subsequent to December 31,
2003, we redeemed approximately $4.9 million of the Series B Stock, including
accrued dividends paid in cash.

         In connection with the original issuance of the subordinated
debentures, we issued to the affiliate detachable warrants to purchase 1,912,833
shares of our common stock, of which 967,000 have been cancelled as of December
31, 2002. The remaining 945,833 warrants were outstanding at December 31, 2003
and have all been exercised at April 26, 2004.

         During 2003, we entered into an agreement to facilitate the private
placement of approximately 1,650,000 shares of our common stock owned by an
affiliate and certain investors. The sale of the stock covered by this agreement
closed in the fourth quarter of 2003 and resulted in our receipt of $0.4 million
cash, which is reflected as a reduction in our general and administrative
expense.

         In order to facilitate a settlement of ongoing litigation between
certain affiliates, we agreed to re-price and extend the maturity dates of
293,055 warrants owned by the defendant affiliates but transferred in settlement
of the litigation to the plaintiff affiliates. The exercise prices of the
transferred warrants ranged from $2.25 - $6.00 per share. The maturity dates of
the transferred warrants ranged from November 1, 2004 to July 1, 2005. The
transferred warrants were re-priced at $1.54 per share and the maturity dates
were extended to November 1, 2006. Our statement of operations includes a
non-recurring charge of approximately $0.1 million representing the differences
if the fair market value of the originally issued warrants and the re-priced
warrants. As of December 31, 2003, all 293,055 re-priced warrants remained
outstanding, but have all been exercised at April 26, 2004.

         The following table summarizes the exercise prices of warrants as of
December 31, 2003:

I, James C. Eckert, certify that:

    1. I have reviewed this amendment to the annual report on Form 10-K/A of
OMNI Energy Services Corp., a Louisiana corporation (the "registrant");

    2. Based on my knowledge, this annual report does not contain any untrue

report;

    3. The registrant's other certifying officers and I, are responsible for
establishing and maintaining disclosure controls and procedures (as defined in
Exchange Act Rules 13a-14 and 15d-14) for the registrant and have:

        a) designed such disclosure controls and procedures 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 annual report is being
    prepared;

        b) evaluated the effectiveness of the registrant's disclosure controls
    and procedures as of a date within 90 days prior to the filing date of this
    annual report (the "Evaluation Date"); and

        c) presented in this annual report our conclusions about the
    effectiveness of the disclosure controls and procedures based on our
    evaluation as of the Evaluation Date;

    4. The registrant's other certifying officers and I have disclosed, based on
our most recent evaluation, to the registrant's auditors and the audit committee
of the registrant's board of directors (or persons performing the equivalent
functions):

        a) all significant deficiencies in the design or operation of internal
    controls which could adversely affect the registrant's ability to record,
    process, summarize and report financial data and have identified for the
    registrant's auditors any material weaknesses in internal controls; and

        b) any fraud, whether or not material, that involves management or other
    employees who have a significant role in the registrant's internal controls;
    and

    5. The registrant's other certifying officers and I have indicated in this
annual report whether there were significant changes in internal controls or in
other factors that could significantly affect internal controls subsequent to
the date of our most recent evaluation, including any corrective actions with
regard to significant deficiencies and material weaknesses.
