OMNI ANNOUNCES EXTENSION OF TIME TO CURE DEFICIENCY

CARENCRO, LA – July 15, 2010 – OMNI ENERGY SERVICES CORP. (NASDAQ GM: OMNI) today announced that NASDAQ has granted the Company an extension of time to regain compliance with NASDAQ Rule 5250(c)(1) (the “Rule”). As previously disclosed by the Company on May 24, 2010, the Company received a standard notification from NASDAQ as a result of the failure to file the Company’s Form 10-Q for the period ended March 31, 2010 (“Form 10-Q”) as required under the Rule.

As previously reported, the Company timely filed a Form 12b-25 with the Securities and Exchange Commission on May 18, 2010 disclosing that “The Audit Committee of the Board of Directors of OMNI Energy Services Corp. (the “Company”), with the assistance of management, is conducting an internal review related to the Company’s accounting for subordinated promissory notes in connection with certain acquisitions which occurred in prior periods. Until the completion of this review, the Company is unable to complete the preparation of its Quarterly Report on Form 10-Q for the quarter ended March 31, 2010. The Company plans to file the Form 10-Q as soon as practicable after the completion of this review, the completion of any additional accounting work required as a result of this review, and after the review of its financial statements for the quarter ended March 31, 2010 by the Company’s independent registered public accountants.”

The Company submitted a plan to regain compliance with the Rule for submission to NASDAQ on July 6, 2010 and was subsequently notified on July 13, 2010 that an extension of time to regain compliance had been granted until November 15, 2010. The terms of the extension provide that the Company must file the Form 10-Q on or before November 15, 2010. If the Company does not meet this deadline, NASDAQ Staff will provide written notification that the Company’s common stock will be delisted, subject to any appeal the Company may initiate. It is the Company’s intention to regain compliance as soon as practicable pending completion of the above mentioned internal review.
