ITEM 5.  OTHER EVENTS.

                  On May 31, 1996, the Registrant acquired from the manufacturer
thereof, Input/Output, Inc. (Input/Output"),  seismic data acquisition equipment
(the  "Equipment")  for an aggregate  of  approximately  $8,500,000  in cash and
refinanced  certain  conditional  sales  agreements  with  Input/Output  for  an
additional  $4,500,000 of equipment.  The Equipment will be used in the ordinary
course of the Registrant's business.

                  A portion  of the  purchase  price for the  Equipment  and the
funds for the refinancing were paid from the proceeds of a $15 million term loan
(the "Term  Loan")  from  First  Interstate  Bank of Texas,  N.A.  (the  "Bank")
pursuant to a Loan Agreement  between the  Registrant and the Bank,  dated as of
May 29,  1996 (the  "Loan  Agreement").  The  Registrant  plans to  utilize  the
remaining $3 million  under the Term Loan to fund future  capital  expenditures.
The Term Loan is payable,  with certain  limited  exceptions,  in equal  monthly
installments  through July 31, 1999.  The Term Loan bears  interest at an annual
rate  equal  to  the  prime  rate  plus  1%  and is  secured  by a  lien  on the
Registrant's  accounts,  accounts receivable,  equipment,  machinery,  fixtures,
inventory,  goods, chattel paper, documents,  instruments,  investment property,
general  intangibles,  and  other  personal  property,  whether  then  owned  or
thereafter acquired, and all products and proceeds thereof, and by guarantees by
each of the Registrant's subsidiaries. The Loan Agreement also provides for a $3
million  revolving credit loan (the "Revolving  Credit Loan") which may be drawn
down from  time to time  through  May 29,  1997 in an amount of up to 70% of the
Registrant's "Eligible Accounts" (as defined in the Loan Agreement). The rate of
interest and the security  for the  Revolving  Credit Loan are the same as those
described above for the Term Loan. In addition to certain customary  affirmative
covenants,  the Loan Agreement  contains  restrictions  on the  Registrant  with
respect to (i)  incurring  Debt (as  defined),  incurring or permitting to exist
Liens (as defined) on its property assets or revenues, (iii) declaring or paying
any dividends or other  distributions  on its capital stock (or acquiring any of
its capital stock),  (iv) issuing capital stock, (v) entering into  transactions
with  affiliates,  (vi)  disposing of assets,  and (vii) with respect to certain
other matters, and contains certain financial  covenants.  The foregoing summary
of the Loan  Agreement  is  qualified  in its  entirety by reference to the Loan
Agreement and other agreements relating thereto, copies of which are attached as
exhibits to this Current Report on Form 8-K.
