ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.

    The business of the Company was founded in 1987 by Mr. Jeansonne. In July
1996, the successor to this business, OMNI Geophysical Corporation ("OGC"), of
which Mr. Jeansonne was a director, executive officer and principal shareholder,
sold substantially all of its assets, other than the land and building on which
the Company's headquarters were then located, to OMNI Geophysical, L.L.C., the
Company's predecessor ("OMNI Geophysical"). At the time of this transaction, Mr.
Jeansonne also retained certain assets used primarily to entertain clients of
the business. Since that time, OMNI Geophysical and the Company have leased the
former headquarters building from OGC for its aviation division under an
agreement that also contained an option to purchase. OMNI Geophysical and the
Company have also used the assets retained by Mr. Jeansonne, and in return have
borne substantially all of the direct costs of client development at these
facilities.

    During the years ended December 31, 1999, 2000 and 2001, we privately placed
with BizCapital (an affiliate of Advantage Capital) subordinated debentures
totaling $7.5 million, $3.4 million and $1.5 million, respectively. The
debentures matured five years from their date of issue and accrued interest at
various rates ranging from a fixed rate of 12% per annum to a variable rate of
interest starting at 12% per annum and escalating to 20% per annum. In October
2000, we agreed to convert $4.6 million of the subordinated debentures into our
Series A Preferred Stock. In May 2001, we agreed to pay the affiliate $3.0
million cash plus issue to the affiliate $4.6 million of the Company's Series B
Preferred Stock in full satisfaction of all of the remaining outstanding
subordinated debentures including accrued interest of $1.8 million. This
transaction resulted in the affiliate agreeing to forgive $1.0 million of
indebtedness which has been reflected as a capital contribution from the
affiliate rather than as income in our financial statements.

    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 outstanding are all exercisable with exercise prices
ranging from $2.25 to $6.00 per share and expire between March 2005 and October
2005.

    The following table summarizes the exercise prices of warrants as of
December 31, 2002:
