reported for the year ended 2002.

         With the effects of certain non-GAAP financial measures, as referenced

comparative results of the Company's financial performance, OMNI reported net
income from continuing operations on a pro forma basis of $5.1 million ($0.58

$46.7 million, with the inclusion of American Helicopters, Inc. for the entire

Helicopters, Inc. for the same twelve-month period ended December 31, 2003. OMNI
acquired American Helicopters, Inc. on November 20, 2003. The 2003 pro forma
results exclude the impact of the Company's recently announced award of a
certain multi-year aviation contract to provide transportation services in the
Gulf of Mexico.

         The Company also reported a non-recurring charge of $0.4 million ($0.04
per diluted share) for the twelve months ended December 31, 2003 in connection
with discontinuing its operations in South America until market conditions
improve in that country. After preferred stock dividends of $0.5 million ($0.05
per diluted share), OMNI reported net income applicable to common and common
equivalent shares of $3.0 million ($0.34 per diluted share) in 2003, a 329%
improvement over the $0.7 million reported for 2002. OMNI previously announced
the redemption of substantially all of its Series A and Series B Preferred Stock
during the first quarter of 2004.

         For the fourth quarter ended December 31, 2003, OMNI reported revenues
of $10.2 million; a 59% increase over the $6.4 million reported for the
three-month period ended December 31, 2002. From continuing operations, OMNI
reported net income of $1.0 million, or $0.10 per diluted share, for the three
months ended December 31, 2003, as compared to a loss of $(0.6) million, or
$(0.07) per diluted share, for the three months quarter ended December 31, 2002.
Cash flow from operations totaled $1.0 for the fourth quarter of 2003, as
compared to $0.3 for the fourth quarter of December 31, 2002.

         "Our impressive 2003 performance resulted from continued attention to
our operating costs and administrative expenses and improved market conditions
in our core business segment, seismic drilling in the Transition Zone,"
commented James C. Eckert, Chief Executive Officer. "2003 was also marked with
crucial milestones in our aviation division. Through internal growth and
acquisitions, we have aggressively increased this core business segment. Our
objective is to develop this business segment into OMNI being recognized as a
leading provider of aviation transportation services in the shallow, offshore
waters of the Gulf of Mexico. Our efforts have been rewarded with the recent
signing of a five-year, $7 million contact to provide aviation transportation
services for an oil and gas company operating in the Gulf of Mexico.







         "By restructuring and reshaping our balance sheet, realigning our
senior debt, and maximizing the use of our continually improving cash flow, we
are not only capable of capitalizing on strategic business opportunities, but we
anticipate reducing debt with excess cash flow. Further, by increasing our
profitability, OMNI's net operating tax loss carryforwards in excess of $30
million are becoming an increasingly valuable asset by reducing income taxes and
preserving cash. 2003 was a challenging year for OMNI. Our management team rose
to the occasion and has postured the company for continued stockholder value
enhancement. We are pleased with the market's reaction to our business
strategy," continued Eckert.

         "The market remains difficult to accurately project future business
activity. Accordingly, we must remain focused on our original objective of
profitability and operating cash flow. To do this, we will maintain cost
constraints, maximize asset utilization and concentrate on employee efficiency,"
added Eckert. "We must continue expanding the services we provide to our
customers requiring us to pursue various strategic business opportunities. In
doing so, we will methodically explore and evaluate transactions, that not only
expand and complement our core businesses, but also add value and enhance these
same business segments. Certain opportunities are currently under consideration
which could present exciting opportunities for OMNI. We are committed to
continue as a leading provider of integrated services to the oil and gas
industry. By doing so, we believe we will provide the maximum, long-term value
for our stockholders," concluded Eckert.

         Headquartered in Carencro, LA, OMNI Energy offers a broad range of
integrated services to geophysical companies engaged in the acquisition of
on-shore seismic data and through its aviation division, transportations
services to oil and gas companies operating in the shallow, offshore waters of
