            OMNI ISSUES $5.05 MILLION OF 6.5% CONVERTIBLE DEBENTURES
                   Company Secures Additional Working Capital

         CARENCRO, LA - APRIL 15, 2004 - OMNI ENERGY SERVICES CORP. (NASDAQ NM:
OMNI), announced today it has entered into an agreement to issue $5.05 million
of 6.5% Convertible Debentures (the "Debentures") to funds managed by Gemini
Investment Strategies, LLC and two other institutional investors. The Debentures
mature in April 2007, include a conversion rate of $7.20 per share and, if
converted, are convertible into approximately 700,000 shares of OMNI common
stock. The Company will initially use the proceeds for working capital purposes.

         Under the terms of the agreement, the holders of the Debentures will
also have the right to require the repayment or conversion of up to $4.419
million of the Debentures earlier than maturity ("Put Option"). The Put Option
can be exercised in ten consecutive and equal monthly installments commencing
the first (or second depending on effective registration date) full month
following the date on which a registration statement filed with the Securities
and Exchange Commission to register the underlying common shares is declared
effective. Upon receipt by OMNI of the debenture holders' intent to exercise the
Put Option, the Company will have the irrevocable option to deliver cash or
common stock with respect to the Put Option. If the Company elects to pay the
Put Option with common stock, the underlying shares will be valued at a 12.5%
discount to the average trading price of OMNI common stock for the applicable
pricing period, as defined by the agreement.

         The Company also issued Warrants representing the right to purchase in
the aggregate 151,500 shares of common stock with an exercise price of $9.00 per
share (subject to adjustment as provided therein). The Warrants may be exercised
at any time beginning on the date that is six months and one day after the date
the warrants are issued. The Warrants may not be exercised after the fifth
anniversary of the date the Warrants become exercisable.
