terms and conditions of this Agreement, the Bank agrees to extend
credit  to  the Borrower during the period from the  date  hereof
until  the Termination Date (a) by making Revolving Loans to  the

irrevocable  standby  and  commercial  letters  of  credit  (said
irrevocable  standby  and  commercial  letters  of  credit  being
referred  to  herein  as the "Credits") for the  account  of  the
Borrower  from time to time; provided, however, that at  no  time
shall  the sum of (1) the aggregate principal amount of Revolving
Loans  to  the  Borrower at such time outstanding, plus  (2)  the
aggregate  unfunded amount of Credits issued for the  account  of
the  Borrower at such time outstanding, exceed the Borrowing Base
Amount then in effect.  In the event, at any time, and from  time
to  time, the sum of all outstanding Revolving Loans and  Credits
issued and outstanding to the Borrower exceeds the Borrowing Base
Amount  then  in effect, the Borrower shall prepay the  Revolving
Loans  by such an amount to cause the sum of the Revolving  Loans
and  Credits  outstanding to the Borrower to equal the  Borrowing
Base Amount (or, at the option of the Bank, the Borrower may post
cash  collateral to secure such deficiency in the Borrowing  Base
Amount).

     Section 2.2.  Revolving Loans.

      Section 2.2.1.  Revolving Loans.  Subject to the terms  and
conditions  of this Agreement, the Bank agrees to make  Revolving
Loans  to  the Borrower from time to time during the period  from
the  date hereof to and including the Termination Date; provided,
however,  that (1) no such Revolving Loan shall exceed an  amount
which,  when added to (i) the aggregate principal amount  of  all
Revolving  Loans  to the Borrower at such time outstanding,  plus
(ii)  the aggregate undisbursed amount of Credits issued for  the
account  of  the Borrower at such time outstanding,  exceeds  the
Borrowing  Base  Amount then in effect.  Within  the  limits  set
forth  herein,  the Borrower may borrow from the Bank  hereunder,
repay  any  and all such Revolving Loans as hereinafter  provided
and  reborrow hereunder.  The Borrower's obligation to repay  the
Revolving Loans made by the Bank shall be evidenced by  a  master
promissory  note  of  the Borrower (said  promissory  note  being
herein referred to as the "Revolving Note"), payable to the order
of  the Bank in the principal sum of $10,000,000.00 or such other
or  lesser amount as may be reflected from time to time on the on
the  books  and  records of the Bank as evidencing the  aggregate
unpaid  principal  balance of all Revolving  Loans  made  to  the
Borrower, with a final maturity of January 20, 2000, and  bearing
interest  at  the  rate  or rates from time  to  time  in  effect
pursuant  to  the  terms of Article VI hereof.  Interest  on  the
Revolving Note shall be payable in accordance with the  terms  of
Section 6.2 hereof.

      Section  2.2.2.  Manner and Notice of Borrowing  Under  the
Revolving  Loan  Commitment.  Requests  For  Advances  under  the
Revolving Loan Commitment may be made by the Borrower in  person,
in   writing   (including  facsimile  transmission)  or   through
telephone  calls  to the Bank and such requests  shall  be  fully
authorized  by  the Borrower if made by any one  of  the  persons
designated  by  the Borrower in writing to the  Bank.   The  Bank
shall  have  the  right, but not the obligation,  to  verify  any
telephone requests by calling the person who made the request  at
the telephone number designated by the Borrower in writing to the
Bank.   Requests For Advances must be received by not later  than
11:00  a.m.  (Central Time) on the date of the proposed  advance.
Not later than the close of business on the date of such request,
assuming  all conditions of this Agreement for such  advance  has
been  satisfied,  the  Bank will make such advance.   The  amount
thereof  shall  be  credited by the Bank to the checking  account
maintained  in  the name of the Borrower with the  Bank  and  the
credit  advice  resulting  therefrom  shall  be  mailed  to   the
Borrower.  The Bank's copy of such credit advice indicating  such
deposit to the account of the Borrower shall be deemed conclusive
evidence of the Borrower's indebtedness to the Bank in connection
with  such  borrowing.   The  aggregate  outstanding  amount   of
principal  and  interest due by the Borrower at  any  given  time
under  the Revolving Loan Commitment shall be and constitute  the
indebtedness of the Borrower to the Bank under the Revolving Note
made  by the Borrower.  When each advance is made by the Bank  to
the  Borrower  hereunder, the Borrower shall be  deemed  to  have
renewed  and  reissued its Revolving Note for the amount  of  the
advance  plus all amounts due by the Borrower to the  Bank  under
the Revolving Loan Commitment immediately prior to such advance.

       Section  2.2.3.   Borrowings  Under  the  Revolving   Loan
Commitment.   Within the limits of the Revolving Loan  Commitment
to the Borrower hereunder and subject to the terms and conditions
of  this Agreement, the Bank shall only be obligated to lend  the
Borrower an amount which will not cause its Borrowing Base Amount
to  be  exceeded.   During  the  period  of  the  Revolving  Loan
Commitment, the Borrower may use the Revolving Loan Commitment by
borrowing, prepaying and reborrowing, all in accordance with  the
terms and conditions of this Agreement.

      Section  2.2.4.  Payment of the Revolving  Note  Under  the
Revolving  Loan  Commitment.  Interest on  the  unpaid  principal
balance of the Revolving Note shall be payable in accordance with
the  terms of Section 6.2 hereof.  Principal shall be payable  on
the Termination Date; provided, however, in the event at any time
the  aggregate  outstanding principal amounts  of  the  Revolving
Loans  to  the  Borrower,  when added to the  aggregate  unfunded
amounts  of  Credits at such time outstanding  to  the  Borrower,
causes  its  Borrowing Base Amount to be exceeded,  the  Borrower
shall  immediately upon demand by the Bank prepay  its  Revolving
Note  in  an  amount  necessary to cause the aggregate  principal
amount  of its unpaid Revolving Loans plus the aggregate unfunded
amount of its Credits to equal its Borrowing Base Amount (or,  at
the option of the Bank, the Borrower may post cash collateral  to
secure  such  deficiency  in  its Borrowing  Base  Amount).   The
Borrower hereby authorizes the Bank to debit the Dominion Account
to  pay  interest  due  on the Revolving Note  on  each  Interest
Payment  Date,  and  to credit all proceeds  of  the  Receivables
received  in the Dominion Account when collected (or earlier,  if
the Bank in its sole discretion allows such funds to be available
to  the  Borrower prior to the date on which any checks or  other
instruments   given  in  payment  of  Receivables  are   actually
collected)  towards  payment of the Revolving  Loans  outstanding
under  the  Revolving Note.  Further, in the event  there  is  no
outstanding   debt  under  the  Revolving  Note,   the   Borrower
authorizes the Bank to sweep daily the proceeds from the Dominion
Account  into  the Borrower's operating account with  Bank.   The
Bank  agrees to give notice to the Borrower of any debits to  the
said  funding  account  used  to pay interest  within  three  (3)
Business Days following each such debit.

     Section 2.2.5.  Reserved

      Section 2.2.6.  Proceeds of Dominion Account.  The Borrower
has executed a lockbox agreement with the Bank, pursuant to which
all  checks, drafts and other instruments evidencing  payment  of
the  Borrower's Receivables shall be delivered to  the  Bank  and
deposited  into  the  Borrower's  Dominion  Account  more   fully
described   in   Section  11.14  hereof.   The  Borrower   hereby
authorizes  the Bank to apply, on a daily basis, the proceeds  of
all  its accounts receivable actually collected (or, at the  sole
discretion of the Bank, amounts which have been received but  not
yet  collected) by the Bank from the Dominion Account  to  reduce
the  outstanding  principal balance of the Revolving  Loans  due.
Such  payments will adjust availability immediately for  purposes
of  loan  availability and on the next day  for  bookkeeping  and
interest purposes.

     Section 2.2.7.  Use of Proceeds.  The Borrower shall use the
proceeds  of  the Revolving Loan Commitment solely  to  refinance
existing indebtedness incurred by Omni Geophysical and thereafter
to  finance  working capital requirements and  general  corporate
purposes of the Borrower.

     Section 2.2.8.  Overlines and Overadvances.  Notwithstanding
the  provisions of Section 2.2.1 hereof, in the event that at any
time the aggregate unpaid principal amount of the Revolving Loans
ever  exceeds  $10,000,000 (the maximum possible  amount  of  the
Borrowing  Base  Amount), the Borrower agrees to pay  the  excess
amount  (an "overline") immediately upon demand by the Bank.   In
the event the unpaid principal amount of the Revolving Loans ever
exceeds  the  Borrowing Base Amount then in effect, the  Borrower
agrees  to  pay the excess amount (an "overadvance")  immediately
upon  demand by the Bank.  Overlines and overadvances shall  bear
interest  at the rate (or at the highest rate, if more  than  one
rate  is  then  in  effect) borne by the  Revolving  Note.   Upon
request  of  the  Bank, the Borrower shall execute  a  promissory
note,  payable to the order of the Bank, to represent the  amount
of   any   overline   or  overadvance;  however,   the   Borrower
acknowledges  and agrees that the records of the  Bank  and  this
Agreement shall constitute conclusive evidence of any overline or
overadvance  and  the  obligation of the Borrower  to  repay  any
overline  or  overadvance,  with  interest.   All  overlines  and
overadvances for which the Bank has not demanded payment earlier,
and all unpaid and accrued interest on overlines and overadvances
not  due  and  payable earlier, shall be due and payable  on  the
Termination Date.  The Borrower acknowledges and agrees that  the
Bank  is not obligated to the Borrower to fund any advance  which
would create an overline or overadvance.


     Section 2.3.  The Credits.

      Section  2.3.1.  The Credits.  Upon the written application
of  the  Borrower, using the form of letter of credit application
then  normally  required  by  the Bank  in  connection  with  the
issuance of such Credits (the "Credit Application"), executed  by
the  Borrower  (or  by any one of the persons designated  by  the
Borrower  in  writing to the Bank in accordance  with  the  terms
hereof), the Bank agrees, subject to the terms and conditions  of
this  Agreement,  that it will issue its Credit substantially  in
accordance  with the Credit Application.  Credits may  either  be
commercial  letters of credit, in which case they shall  have  an
expiry date on a Business Day not later than the earlier to occur
of  the Termination Date, or standby letters of credit issued  to
secure workers' compensation obligations of the Borrower (or  for
other  purposes  deemed  acceptable  by  the  Bank  in  its  sole
discretion),  in  which case they shall have an expiry  date  not
later  than the earlier to occur of the Termination Date  or  one
year  from  the date of issuance.  In no event shall a Credit  be
issued by the Bank for the account of the Borrower (i) if the sum
of  the  face amount thereof when added to the aggregate unfunded
amount  of  Credits issued for the account of the  Borrower  then
outstanding exceeds $1,000,000.00 or (ii) if the sum of the  face
amount  thereof when added to the  aggregate unfunded  amount  of
Credits  issued for the account of the Borrower then  outstanding
plus the aggregate principal amount of the Revolving Loans to the
Borrower  at  such  time outstanding exceeds the  Borrowing  Base
Amount then in effect.

      Section 2.3.2.  Issuance of Credits.  Each Credit shall  be
issued  not  later than three (3) Business Days after receipt  by
the  Bank  of the Credit Application related thereto.   No  later
than  12:00  noon  (Central  Time)  on  the  third  Business  Day
following  receipt of the Credit Application and upon fulfillment
of  the  applicable conditions set forth in this  Agreement,  the
Bank  shall  issue  its  Credit.  The Bank  may  rely  fully  and
completely  upon  the authority of the signatory  of  the  Credit
Application  and  the contents thereof unless such  authority  is
terminated by written notice delivered to the Bank, and any  such
termination of authority shall be effective only prospectively.

      Section 2.3.3.  Credit Commission.  The Borrower agrees  to
pay  to the Bank the standard fees charged and established by the
Bank from time to time for the issuance and processing of letters
of  credit (the "Credit Commission") with respect to each  Credit
created by the Bank hereunder.  Payment of such Credit Commission
with respect to each Credit created by the Bank shall be paid  in
advance  on the date of issuance of the Credit.  With respect  to
standby  Credits  issued hereunder, the Borrower  unconditionally
agrees  to  pay  to the Bank, in addition to the Bank's  standard
fees  for  the  issuance  and  processing  of  such  Credits,   a
commission, payable in advance on or before the date of  issuance
of  each Credit, calculated at the rate of 1.50% per annum on the
face amount of each Credit, based upon the number of days of  the
term  of each such Credit divided by 360, which commission  shall
not be less than $300.00 per standby letter of credit.

      Section  2.3.4.   Credit Obligations.  The Borrower  agrees
unconditionally  to  pay  the Bank on  demand  in  United  States
currency   at  the  Bank's  principal  office  in  New   Orleans,
Louisiana,  the  amount required to pay (a) any  and  all  drafts
drawn  and any and all demands made or purported to be made under
any  Credit  issued  for  its account, (b)  any  and  all  costs,
charges,  fees and/or expenses incurred or paid by  the  Bank  in
connection  with  any  Credit issued for  its  account,  and  (c)
interest  on such amounts described above under (a)  and  (b)  as
hereinafter provided (the "Credit Obligations").  In the event of
any  drafts  drawn and any and all demands made under any  Credit
are  payable in foreign currency, the Borrower agrees to make the
aforementioned payment to the Bank in  United States currency  at
the  Bank's  selling rate for cable transfers  to  the  place  of
payment  of  such  draft  on  the date  of  such  payment.   Such
obligation  of  the Borrower shall be deemed a Credit  Obligation
hereunder.   The Borrower further agrees to comply with  any  and
all  governmental currency exchange regulations  or  requirements
now  or  hereafter  applicable to such Credit or  to  any  drafts
related  thereto.  The Borrower further authorizes the  Bank,  at
its  option, to compensate itself by applying any part or all  of
the  balance  of  any deposit account or certificate  of  deposit
which  the  Borrower  may maintain with the Bank,  at  any  time,
whether  or not the deposit is mature, and/or any and all  monies
or  property  or  interest of any kind now or  hereafter  in  the
Bank's hands, or in transit to or from the Bank, and belonging to
the  Borrower, to the payment, in whole or in part, of the amount
of  any  draft and all interest, costs and attorney's fees  which
the Borrower may owe the Bank pursuant to this Agreement.  In the
event  a Credit Obligation is not paid when demanded by the Bank,
the  Borrower agrees to pay to the Bank on demand a sum equal  to
the  amount of the Credit Obligation, plus interest thereon  from
the date the Credit Obligation is demanded by the Bank until paid
at the interest rate then in effect under the Revolving Note.   A
payment  shall not be deemed made until funds therefor have  been
actually  collected  and made available to the  Bank.   Upon  the
occurrence of an Event of Default hereunder, the Borrower  agrees
to  pay  to  the  Bank  on demand a sum equal  to  the  aggregate
unfunded  amounts  of  all  Credits  outstanding,  together  with
interest  thereon  at the Base Rate, or at  any  higher  rate  of
interest which the Bank may impose as a default rate pursuant  to
the terms of the Borrower's Revolving Note issued pursuant to the
terms  hereof (such obligation of the Borrower shall be deemed  a
Credit  Obligation  as  such  term is  used  herein).   Upon  the
occurrence  of such Event of Default, the Bank may  exercise  its
right  of offset and compensation set forth above in this Section
2.3.4.   Any amount which the Bank offsets or which the  Borrower
may  pay  to the Bank in excess of drafts actually drawn  on  any
outstanding  Credits,  shall be held by the  Bank  in  pledge  to
secure the payment of future drafts until the Commitments to  the
Borrower  have been terminated, all Indebtedness of the  Borrower
has  been  paid  in full, and no further Credits issued  for  the
account of the Borrower are outstanding.

      Section 2.3.5.  Revolving Loans.  In the event that  Credit
Obligations owed the Bank by the Borrower are not paid  when  due
for   any  reason  including  Credit  Obligations  arising   upon
occurrence of an Event of Default hereunder, notwithstanding  the
limitation  contained in Section 2.2.1, such  Credit  Obligations
shall  be  immediately paid by the Borrower pursuant to Revolving
Loans  in  the  amount of such Credit Obligations.   Such  Credit
Obligations shall be immediately converted to Revolving Loans  by
the Bank and evidenced by the Revolving Note.  If at any time any
Event  of  Default occurs and any portion of any Credits  remains
unfunded, the Borrower for whose account such Credits were issued
shall  pay to the Bank in cash for application to future drawings
under  the  outstanding Credits, an amount equal to the aggregate
unfunded  portion of the outstanding Credits.   If  the  Borrower
does   not  pay  such  amount  on  demand,  notwithstanding   the
limitation  contained  in Section 2.2.1,  such  amount  shall  be
immediately  paid  by  the Borrower by  Revolving  Loans  to  the
Borrower  from  the  Bank.   Such  amount  shall  be  immediately
converted  to a Revolving Loan by the Bank and shall be evidenced
by  the Revolving Note.  The amount of such Revolving Loans shall
be  held  by  the  Bank in pledge securing all of the  Borrower's
obligations  under  this  Agreement,  with  the  Borrower  hereby
granting the Bank a continuing security interest in such funds as
security   for  the  Indebtedness  of  the  Borrower  until   the
Commitments have all terminated, all Indebtedness of the Borrower
has  been  paid  in full, and no further Credits issued  for  the
account of the Borrower are outstanding.

      Section  2.3.6.  Hold Harmless.  The Bank  shall  have  the
right  to deliver the Credit through any correspondents or agents
(the  "Correspondents") that the Bank in its sole discretion  may
choose.   Except  in the case of the Bank's gross  negligence  or
willful  misconduct, the Borrower shall hold  the  Bank  harmless
from  any actions that arise out of the handling of such delivery
by  the Correspondents making the delivery.  The Borrower further
agrees  that the Bank and any Correspondent shall not in any  way
be  responsible for performance by any beneficiary of obligations
to   the  Borrower  nor  for  the  form,  validity,  sufficiency,
correctness,   truthfulness  or  genuineness  of  any   documents
delivered  in connection with any Credit, even if such  documents
should  in  fact  prove  to be in any or  all  respects  invalid,
insufficient,  fraudulent or forged; for failure  of  any  Credit
draft  to bear any reference or correct reference to the  Credit;
for  errors, omissions, or delays in transmission or delivery  of
any  messages,  whether  by  mail,  cable,  teletransmission,  or
otherwise;  or  for  any  error,  neglect  or  default   of   any
Correspondents.  The Borrower further agrees that, if any of  the
above events should occur, such event will not affect, impair  or
prevent  the Borrower's liability or the Bank's rights or  powers
hereunder.   No  liability shall attach to the  Bank  or  to  the
Correspondents  for  any  losses or  damage,  in  consequence  of
present or future laws, censorships, regulations, decrees, orders
or  restrictions, right or wrongfully exercised by an de facto or
de  jure government or governmental agency.  Without limiting the
foregoing,  and  in addition to any other provision  hereof,  the
Bank  is  hereby expressly authorized and directed to  honor  any
request  for  payment which is made under and in compliance  with
the  terms of the Credit without regard to, and without any  duty
on the Bank's part to inquire into, the existence of any disputes
or  controversies between the Borrower and the beneficiary or any
other  person,  firm, or corporation, or the  respective  rights,
duties  or  liabilities of any of them or whether  any  facts  or
occurrences  represented  in any documents  presented  under  the
Credit are true and correct.  The Borrower fully understands  and
agrees that the sole obligation of the Bank to the Borrower shall
be  limited  to honoring requests for payment made under  and  in
compliance with the Credit and the obligation of the Bank remains
so limited even if the Bank may have assisted the Borrower in the
preparation  of  the  wording  of the  Credit  or  any  documents
required  to be presented thereunder or if the Bank may otherwise
be aware of the underlying transaction giving rise to the Credit.
If the Bank, in its sole discretion and at the written request of
the  Borrower, agrees to any change or modification to the amount
or  terms  of  any  Credit or any instrument or document  related
thereto, the Borrower agrees that this Agreement shall be binding
upon  it  with  regard to any changes or modifications  and  with
regard  to  any  actions taken by the Bank or by  any  agents  or
Correspondents relative thereto.



                           ARTICLE III

                       ACQUISITION LOANS

      Section 3.1.  The Acquisition Loan Commitment.  Subject  to
the  terms  and conditions of this Agreement, the Bank agrees  to
extend  credit  to the Borrower during the period from  the  date
hereof until January 20, 1999 by making Acquisition Loans to  the
Borrower  from  time  to time for the account  of  the  Borrower;
provided,  however,  (i)  advances  under  the  Acquisition  Loan
Commitment  are  subject to a sublimit for geophysical  equipment
purchases and loan availability limits, all as set forth  in  the
definition of Borrowing Base Amount applicable to the Acquisition
Loan  Commitment, and (ii) that at no time shall the sum  of  the
aggregate  principal amount of Acquisition Loans to the  Borrower
at such time outstanding exceed the Borrowing Base Amount then in
effect.   In the event, at any time, and from time to  time,  the
sum  of  all outstanding Acquisition Loans issued and outstanding
to the Borrower exceeds the Borrowing Base Amount then in effect,
the Borrower shall prepay the Acquisition Loans by such an amount
to  cause  the  sum of the Acquisition Loans outstanding  to  the
Borrower to equal the Borrowing Base Amount (or, at the option of
the  Bank,  the Borrower may post cash collateral to secure  such
deficiency  in the Borrowing Base Amount).  The Acquisition  Loan
Commitment is a non-revolving loan commitment.

     Section 3.2.  Acquisition Loans.

      Section 3.2.1.  Acquisition Note.  Subject to the terms and
conditions of this Agreement, the Bank agrees to make Acquisition
loans to the Borrower from time to time during the period of  the
date  hereof to January 20, 1999, provided however, that  (1)  no
such Acquisition Loan shall exceed an amount which, when added to
(i)  the  aggregate principal amount of all Acquisition Loans  to
the  Borrower at such time outstanding exceeds the Borrowing Base
Amount  then in effect.  The Borrower's obligation to  repay  the
Acquisition Loans made by the Bank shall be evidenced by a master
promissory  note  of  the Borrower (said  promissory  note  being
herein  referred to as the "Acquisition Note"),  payable  to  the
order  of the Bank in the principal sum of $9,000,000.00 or  such
other  or lesser amount as may be reflected from time to time  on
the  books  and  records of the Bank as evidencing the  aggregate
unpaid  principal  balance  of  Acquisition  Loans  made  to  the
Borrower, with a final maturity of January 20, 2000, and  bearing
interest  at  the  rate  or rates from time  to  time  in  effect
pursuant  to  the  terms of Article VI hereof.  Interest  on  the
Acquisition Note shall be payable in accordance with the terms of
Section 6.2 hereof.

      Section  3.2.2.  Manner and Notice of Borrowing  Under  the
Acquisition  Loan  Commitment.  Requests For Advances  under  the
Acquisition  Loan  Commitment may be  made  by  the  Borrower  in
person,  in writing (including facsimile transmission) or through
telephone  calls  to the Bank and such requests  shall  be  fully
authorized  by  the Borrower if made by any one  of  the  persons
designated  by  the Borrower in writing to the  Bank.   The  Bank
shall  have  the  right, but not the obligation,  to  verify  any
telephone requests by calling the person who made the request  at
the telephone number designated by the Borrower in writing to the
Bank.   Requests For Advances must be received by not later  than
11:00  a.m.  (Central Time) on the date of the proposed  advance.
Not later than the close of business on the date of such request,
assuming  all conditions of this Agreement for such  advance  has
been  satisfied,  the  Bank will make such advance.   The  amount
thereof  shall  be  credited by the Bank to the checking  account
maintained  in  the name of the Borrower with the  Bank  and  the
credit  advice  resulting  therefrom  shall  be  mailed  to   the
Borrower.  The Bank's copy of such credit advice indicating  such
deposit to the account of the Borrower shall be deemed conclusive
evidence of the Borrower's indebtedness to the Bank in connection
with  such  borrowing.   The  aggregate  outstanding  amount   of
principal  and  interest due by the Borrower at  any  given  time
under the Acquisition Loan Commitment shall be and constitute the
indebtedness  of  the Borrower to the Bank under the  Acquisition
Note made by the Borrower.  When each Acquisition Loan is made by
the  Bank to the Borrower hereunder, the Borrower shall be deemed
to  have renewed and reissued its Acquisition Note for the amount
of  the advance plus all amounts due by the Borrower to the  Bank
under  the Acquisition Loan Commitment immediately prior to  such
advance.

      Section  3.2.3.   Borrowings  Under  the  Acquisition  Loan
Commitment.  Within the limits of the Acquisition Loan Commitment
and  subject  to the terms and conditions of this Agreement,  the
Bank shall only be obligated to lend the Borrower an amount which
will not cause the Borrowing Base Amount to be exceeded.

      Section  3.2.4.  Payment of the Acquisition Note Under  the
Acquisition  Loan  Commitment.  Interest on the unpaid  principal
balance  of  the Acquisition Note shall be payable quarterly  for
the first twelve (12) months.  Thereafter, principal and interest
shall  be  paid quarterly based on a five (5) year straight  line
amortization, with a final maturity of January 20, 2000.  In  the
event at any time the aggregate outstanding principal amounts  of
the  Acquisition Loans to the Borrower causes the Borrowing  Base
Amount to be exceeded, the Borrower shall immediately upon demand
by the Bank prepay its Acquisition Note in an amount necessary to
cause  the  aggregate principal amount of its unpaid  Acquisition
Loans  to  equal the Borrowing Base Amount (or, at the option  of
the  Bank,  the Borrower may post cash collateral to secure  such
deficiency  in  its Borrower Base Amount).  The  Borrower  hereby
authorizes the Bank to debit the Dominion Account to pay interest
due  on the Acquisition Note on each Interest Payment Date during
the first twelve (12) months.  The Bank agrees to give notice  to
the  Borrower of any debits to the said funding account  used  to
pay  interest within three (3) Business Days following each  such
debit.

     Section 3.2.5.  Use of Proceeds.  The Borrower shall use the
proceeds  of  the Acquisition Loan Commitment solely  to  finance
capital expenditures and acquisitions.

     Section 3.2.6.  Overlines and Overadvances.  Notwithstanding
the  provisions of Section 3.2.1 hereof, in the event that at any
time  the  aggregate unpaid principal amount of  the  Acquisition
Loans ever exceeds $9,000,000 (the maximum possible amount of the
Borrowing  Base  Amount), the Borrower agrees to pay  the  excess
amount  (an "overline") immediately upon demand by the Bank.   In
the  event  the unpaid principal amount of the Acquisition  Loans
ever  exceeds  the  Borrowing Base Amount  then  in  effect,  the
Borrower  agrees  to  pay  the excess amount  (an  "overadvance")
immediately  upon demand by the Bank.  Overlines and overadvances
shall bear interest at the rate (or at the highest rate, if  more
than  one rate is then in effect) borne by the Acquisition  Note.
Upon request of the Bank, the Borrower shall execute a promissory
note,  payable to the order of the Bank, to represent the  amount
of   any   overline   or  overadvance;  however,   the   Borrower
acknowledges  and agrees that the records of the  Bank  and  this
Agreement shall constitute conclusive evidence of any overline or
overadvance  and  the  obligation of the Borrower  to  repay  any
overline  or  overadvance,  with  interest.   All  overlines  and
overadvances for which the Bank has not demanded payment earlier,
and all unpaid and accrued interest on overlines and overadvances
not  due  and  payable earlier, shall be due and payable  on  the
Termination Date.  The Borrower acknowledges and agrees that  the
Bank  is not obligated to the Borrower to fund any advance  which
would create an overline or overadvance.


                            ARTICLE IV
                                
                            TERM LOAN

      Section  4.1.   The  Term  Loan.   Subject  to  the  terms,
conditions and provisions of this Agreement, the Bank  agrees  to
make  a term loan  (the "Term Loan") to the Borrower in an amount
not to exceed $10,951,810.41 ("Term Loan Commitment").

     Section 4.2.  The Term Note.  The Borrower's indebtedness to
the  Bank  pursuant  to the Term Loan shall  be  evidenced  by  a
promissory  note  of  the Borrower (said  promissory  note  being
herein  referred to as the "Term Note"), payable to the order  of
the  Bank  in  the principal sum of the amount of the  Term  Loan
Commitment,  with  a  final maturity of  January  20,  2000,  and
bearing interest at the rate or rates from time to time in effect
pursuant  to the terms of Article VI hereof the Term  Note.   The
Term  Note  shall  be due and payable in quarterly  installments,
based  on a five (5) year straight line amortization, but with  a
final maturity of January 20, 2000.

      Section 4.3.  Prepayments of the Term Loan.  A two  percent
(2%)  prepayment fee shall be payable by the Borrower to the Bank
in  the  event the Borrower prepays the Term Loan (or any portion
thereof)  within  twelve  (12)  months  from  the  date  of  this
Agreement with loan proceeds from another lender.  Otherwise, the
Borrower shall have the right to prepay the Term Loan in whole or
in  part at any time without payment of premium or penalty, other
than for Funding Losses incurred by the Bank as a result thereof.

     Section 4.4.  Proceeds.  The proceeds of the Term Loan shall
be  used  by the Borrower to refinance the "Bridge Loan" made  to
Omni  Geophysical  and  Aviation by  the  Bank  under  the  First
Restated Agreement.


                            ARTICLE V
                                
                              FEES
                                
      Section  5.1.  Commitment Fee.  In addition to  the  Credit
fees  and  commissions  described in  Section  2.3.3  above,  the
Borrower  shall  pay to the Bank a commitment fee of  $10,792.00,
payable  upon  execution of this Agreement by the Borrower.   The
Borrower  hereby  authorizes  the  Bank  to  debit  its   account
maintained with the Bank for collection of the fee.  In addition,
the  parties  have  entered  into a letter  agreement  addressing
additional commitment fee matters.

     Section 5.2.  Unused Fee.  The Borrower shall pay the Bank a
fee  equal  to  0.38%  per annum on the  unused  portion  of  the
Revolving  Loan  Commitment and the Acquisition Loan  Commitment,
payable  quarterly  in arrears, commencing April  20,  1998,  and
quarterly  thereafter, and on the Termination Date.   The  unused
portion of the Revolving Loan Commitment and the Acquisition Loan
Commitment  shall be determined on a daily basis  by  subtracting
from   $19,000,000.00  the  amount  of  all  Acquisition   Loans,
Revolving  Loans, and Credits outstanding, and by averaging  said
daily  amounts  for  the  period for  which  the  fee  is  to  be
determined.

      Section  5.3.  Stock Option.  The provisions  of  paragraph
3(c)(ii)  of the Second Amendment to the First Restated Agreement
shall remain in effect.


                           ARTICLE VI
                                
                  INTEREST PAYABLE ON THE LOANS
                                
      Section  6.1.  Interest on the Loans.  The unpaid principal
amounts of all Loans or Tranches shall bear interest at the LIBOR
Rate plus the Applicable Margin then in effect for such Loans  as
determined  by the Bank at the time such LIBOR Rate is determined
for any of the Loans or Tranches thereof.

      Section  6.2.   Payment of Interest on the Loans.  Interest
on  all  Loans shall be payable on the last Business Day of  each
quarter  and on the final maturity date of each such  Loan  (each
such interest payment date for any Loan being herein referred  to
as an "Interest Payment Date").


                           ARTICLE VII
                                
                   CERTAIN GENERAL PROVISIONS
                                
      Section  7.1.   Payments  to the  Bank.   All  payments  of
principal,  interest, commitment fees and any other  amounts  due
hereunder  or under any of the other Related Documents  shall  be
made  to  the Bank at the Bank's office at 313 Carondelet Street,
New  Orleans, Louisiana 70130, or at such other location that the
Bank  may from time to time designate in writing to the Borrower,
in each case in immediately available funds.

      Section 7.2.  No Offset, etc.  All payments by the Borrower
hereunder and under any of the other Related Documents  shall  be
made  without  setoff or counterclaim and free and clear  of  and
without   deduction  for  any  taxes,  levies,  imposts,  duties,
charges,   fees,  deductions,  withholdings,  compulsory   loans,
restrictions or conditions of any nature now or hereafter imposed
or  levied  by  any  jurisdiction or  any  political  subdivision
thereof  or taxing or other authority therein unless the Borrower
is  compelled  by law to make such deduction or withholding.   If
any such obligation is imposed upon the Borrower with respect  to
any amount payable by it hereunder or under any of the other Loan
Documents,  the  Borrower will pay to the Bank, on  the  date  on
which  such  amount is due and payable hereunder  or  under  such
other  Related  Document, such additional amount  in  Dollars  as
shall  be  necessary to enable the Bank to receive the  same  net
amount which the Bank would have received on such due date had no
such  obligation  been imposed upon the Borrower.   The  Borrower
will  deliver  promptly to the Bank certificates or  other  valid
vouchers  for  all taxes or other charges deducted from  or  paid
with  respect to payments made by the Borrower hereunder or under
such other Loan Documents.

     Section 7.3.  Computations.  All computations of interest on
the  Loans  and  of  commitment or other fees shall  be  assessed
utilizing a 360-day daily interest factor over the number of days
in an actual calendar year (365 days or 366 days in a leap year).
The  Bank  shall determine each interest rate applicable  to  the
Loans   in  accordance  with  this  Agreement,  and  the   Bank's
determination  of  same shall be conclusive  in  the  absence  of
manifest  error.  Except as otherwise provided in the  definition
of  the  term "Interest Period", whenever a payment hereunder  or
under  any of the other Related Documents becomes due  on  a  day
that  is not a Business Day, the due date for such payment  shall
be  extended  to the next succeeding Business Day,  and  interest
shall  accrue during such extension.  The outstanding  amount  of
the  Loans as reflected on the Bank's books and records from time
to  time  shall  be  prima  facie  evidence  of  the  amounts  so
outstanding.

      Section  7.4.  Inability to Determine LIBOR Rate.   In  the
event, prior to the commencement of any Interest Period, the Bank
shall  determine  or  be  notified that adequate  and  reasonable
methods  do not exist for ascertaining the LIBOR Rate that  would
otherwise determine the rate of interest to be applicable to  the
Loans  during any Interest Period, the Bank shall forthwith  give
notice  of  such  determination (which shall  be  conclusive  and
binding  on  the  Borrower) to the Borrower.  In such  event  the
Loans  (or any Tranches thereof) will automatically, on the  last
day  of then current Interest Period applicable to such Loans  or
Tranches, become a Base Rate Loan until the Bank determines  that
the circumstances giving rise to such suspension no longer exist,
whereupon the Bank shall so notify the Borrower.

       Section  7.5.   Illegality.   Notwithstanding  any   other
provisions  herein,  if  any present or future  law,  regulation,
treaty  or directive or the interpretation or application thereof
shall  make  it  unlawful  for the Bank  to  make  available,  or
maintain in effect, the LIBOR Rate, the Bank shall forthwith give
notice  of  such circumstances to the Borrower and thereupon  any
Loans  bearing  interest  at  a LIBOR  Rate  shall  be  converted
automatically to Base Rate Loans on the last day of then  current
Interest  Period applicable to such Loans or within such  earlier
period  as  may  be required by law.  The Borrower  hereby  agree
promptly to pay the Bank, upon demand by the Bank, any additional
amounts  necessary to compensate the Bank for any costs  incurred
by  the  Bank  in making any conversion in accordance  with  this
paragraph, including any interest or fees payable by the Bank  to
lenders  of  funds obtained by it in order to make available,  or
maintain in effect, the LIBOR Rate for the Loans.

      Section  7.6.   Additional Costs, etc.  If any  present  or
future applicable law, which expression, as used herein, includes
statutes,  rules  and regulations thereunder and  interpretations
thereof  by any competent court or by any governmental  or  other
regulatory  body  or official charged with the administration  or
the interpretation thereof and requests, directives, instructions
and  notices at any time or from time to time hereafter made upon
or  otherwise  issued to the Bank by any central  bank  or  other
fiscal,  monetary or other authority (whether or not  having  the
force of law), shall:

     (1)   subject  the  Bank  to any tax,  levy,  impost,  duty,
     charge,  fee,  deduction or withholding of any  nature  with
     respect  to  this Agreement, the other Related Documents  or
     the Indebtedness (other than taxes based upon or measured by
     the revenue, income or profits of the Bank), or
     
     (2)   materially  change the basis of taxation  (except  for
     changes  in taxes on revenue, income or profits) of payments
     to  the  Bank  of  the principal of or the interest  on  the
     Indebtedness of any other amounts payable to the Bank  under
     this Agreement or the other Related Documents, or
     
     (3)  impose or increase or render applicable (other than  to
     the  extent  specifically provided  for  elsewhere  in  this
     Agreement)   any   special  deposit,  reserve,   assessment,
     liquidity,  capital  adequacy or other similar  requirements
     (whether or not having the force of law) against assets held
     by,  or  deposits in or for the account of, or loans by,  or
     commitments of an office of the Bank, or
     
     (4)  impose on the Bank any other conditions or requirements
     with  respect  to  this Loan Agreement,  the  other  Related
     Documents, the Indebtedness, or any class of loans of  which
     the  Indebtedness forms a part, and the result of any of the
     foregoing is
     
                (i)   to increase the cost to the Bank of making,
          funding,  issuing, renewing, extending  or  maintaining
          the Indebtedness or issuing Credits, or
          
                (ii)  to reduce the amount of principal, interest
          or  other  amount  payable to  the  Bank  hereunder  on
          account of such the Indebtedness, or
          
                (iii)     to require the Bank to make any payment
          or   to  forego  any  interest  or  other  sum  payable
          hereunder,  the  amount of which  payment  or  foregone
          interest or other sum is calculated by reference to the
          gross  amount of any sum receivable or deemed  received
          by  the Bank from Borrower hereunder, then, and in each
          such  case, the Borrower will, upon demand made by  the
          Bank at any time and from time to time and as often  as
          the  occasion therefor may arise, pay to the Bank  such
          additional  amounts as will be sufficient to compensate
          the  Bank for such additional cost, reduction,  payment
          or foregoing interest or others sum.
          
      Section  7.7.  Capital Adequacy.  If after the date  hereof
the  Bank  determines that (a) the adoption of or change  in  any
law,   governmental  rule,  regulations,  policy   guideline   or
directive  (whether  or not having the force  of  law)  regarding
capital requirements for banks or bank holding companies  or  any
change in the interpretation or application thereof by a court or
governmental  authority  with appropriate  jurisdiction,  or  (b)
compliance  by the Bank or any corporation controlling  the  Bank
with any law, governmental rule, regulation, policy, guideline or
directive  (whether or not having the force of law) of  any  such
entity regarding capital adequacy, has the effect of reducing the
return  on the Bank's Loans to a level below that which the  Bank
could  have  achieved but for such adoption, change or compliance
(taking into consideration the Bank's then existing policies with
respect to capital adequacy and assuming full utilization of such
entity's  capital)  by  any  amount deemed  by  the  Bank  to  be
material,  then the Bank may notify the Borrower  of  such  fact.
The  Borrower  agrees  to pay the Bank for  the  amount  of  such
reduction in the return on capital as and when such reduction  is
determined  upon  presentation by the Bank of a certification  in
accordance with Section 7.8.

      Section  7.8.   Certificate; Optional Right of  Prepayment.
The  Bank  shall provide the Borrower with a certificate  setting
forth  any  additional amounts which it declares  to  be  payable
pursuant   to  Sections  7.6  and  7.7  hereof,  and  a  complete
explanation  of  such  amounts  which  are  due,  and  each  such
certificate shall be conclusive, absent manifest error, that such
amounts are due and owing.  The Borrower shall have the right, at
any  time  within 90 days of receipt of any such certificate,  to
prepay all the Loans (subject to any and all prepayment penalties
and  obligations to pay Funding Losses under the  terms  of  this
Agreement)  without  being obligated to pay any  such  additional
costs  set forth in such certificate, after which the Bank  shall
promptly  terminate,  discharge and release  of  record  (at  the
Borrowers'  expense)  all  of  its  Encumbrances  affecting   the
Collateral and return all Collateral to the Borrower.

      Section  7.9.  Indemnity.  The Borrower agrees to indemnify
the  Bank and to hold the Bank harmless from and against any  and
all  Funding Losses or any other loss, cost or expense  that  the
Bank may sustain or incur as a consequence of (a) default by  the
Borrower in payment of the principal amount of or any interest on
any  Indebtedness as and when due and payable, including any such
loss or expense arising from interest or fees payable by the Bank
to lenders of funds obtained by it in order to maintain its LIBOR
Rate in effect for the Loans, or (b) the making of any payment of
Indebtedness on a day that is not the last day of the  applicable
Interest  Period, including interest or fees payable by the  Bank
to lenders of funds obtained by it in order to maintain its LIBOR
Rate in effect for the Loans.

                  REPRESENTATIONS AND WARRANTIES

      The Borrower and the Guarantor represent and warrant to the
Bank as follows:

      Section  10.1.  Corporate Authority.  Each  Borrower  is  a
corporation  duly created, validly existing and in good  standing
under  the  laws of its state of Louisiana, and is duly qualified
and  in  good  standing  as a foreign corporation  in  all  other
jurisdictions where the failure to qualify would have an  adverse
effect  upon  its ability to perform its obligations  under  this
Agreement and all Related Documents.  The Borrower has the  power
to enter into this Agreement, issue the Notes, mortgage and grant
the  liens and security interests in the Collateral in the manner
and  for  the  purpose contemplated by the Collateral  Documents.
The  Borrower has the corporate power to perform its  obligations
hereunder  and  under  the  Related Documents.   The  making  and
performance  by  the Borrower of the Related Documents  have  all
been  duly  authorized by all necessary company action (including
all necessary member action), and do not and will not violate any
provision  of  any law, rule, regulation, order, writ,  judgment,
decree,  determination  or  award  presently  in  effect   having
applicability  to  the Borrower or the articles of  incorporation
and/or bylaws of the Borrower.  The making and performance by the
Borrower of the Related Documents to which it is a party  do  not
and  will not result in a breach of or constitute a default under
any  indenture or loan or credit agreement or any other agreement
or instrument to which the Borrower is a party or by which it may
be  bound or affected, or result in, or require, the creation  or
imposition of any mortgage, deed of trust, pledge, lien, security
interest or other charge or encumbrance of any nature (other than
as contemplated by the Related Documents) upon or with respect to
any  of  the  properties now owned or hereafter acquired  by  the
Borrower,  and  the  Borrower  is not  in  default  under  or  in
violation   of   any   such   order,  writ,   judgment,   decree,
determination,  award, indenture, agreement or instrument.   Each
of  the  Related  Documents to which  the  Borrower  is  a  party
constitutes  a  legal,  valid  and  binding  obligations  of  the
Borrower, enforceable in accordance with its terms.  Omni  Marine
is  a  corporation duly created, validly existing,  and  in  good
standing under the laws of the State of Louisiana.  Omni Marine's
execution  of  this Agreement, the Guaranty, and  the  Collateral
Documents  to  which it is a party, has been  authorized  by  all
necessary corporate action, and each such document constitutes  a
legal,  valid, and binding obligation of Omni Marine, enforceable
in  accordance  with its terms.  Aviation is a limited  liability
company  duly  created, validly existing, and  in  good  standing
under  the laws of the State of Missouri.  Aviation is registered
to  do  business in the State of Louisiana.  Aviation's execution
of  this Agreement, the Guaranty, and the Collateral Documents to

obligation of Aviation, enforceable in accordance with its terms.

the  date  or  dates thereof.  Each of said financial  statements
were  prepared  in  conformity  with  GAAP  applied  on  a  basis
consistent  with the preceding year.  No Material Adverse  Change

Guarantor,  as applicable, has good and marketable title  to  the
Collateral,  free  and  clear  of  all  Encumbrances  other  than

interests    covered   thereby,   subject   only   to   Permitted
Encumbrances.

     Section 10.4.  Litigation.  Other than as has been disclosed
previously  to  the Bank in writing, there are no legal  actions,
suits  or  proceedings pending or threatened against or affecting
the  Borrower,  the Guarantor, or any of their properties  before
any  court  or administrative agency (federal, state  or  local),
which,  if  determined adversely to any of the  Borrower  or  the
Guarantor  would constitute a Material Adverse Change to  any  of
them,  and  there  are  no  judgments or  decrees  affecting  the
Borrower  or  its  property (including, without  limitation,  the
Collateral)  which are or may become an Encumbrance against  such
property.

       Section  10.5.   Approvals.   No  authorization,  consent,

Guarantor  agree to supply original or certified  copies  of  the
same to the Bank within the time periods required above.

adversely   affecting  the  business,  properties,   assets,   or
operations  of  the  Borrower  or  the  Guarantor  or   its/their
condition  (financial  or otherwise), and the  Borrower  and  the
Guarantor  are  not in default in the performance, observance  or
fulfillment  of any of the obligations, covenants  or  conditions
contained  in  any agreement or instrument to which  they  are  a
party, which default would constitute a Material Adverse Change.

      Section 10.9.  Default or Event of Default.  No Default  or
Event of Default hereunder has occurred or is continuing or  will
occur as a result of the giving effect hereto.

      Section  10.10.   Employee Benefit  Plans.   Each  employee

hereunder  of  which it has knowledge or should  have  knowledge,
(ii) the filing of any actions, suits or proceedings against  the

Borrower and the Guarantor further agree to furnish the Bank with
evidence that such taxes, assessments, and governmental and other
charges  due by the Borrower and the Guarantor have been paid  in
full  and  in a timely manner.  The Borrower and/or the Guarantor
may withhold any such payment or elect to contest any lien if the
Borrower  and/or  the Guarantor are in good faith  conducting  an
appropriate proceeding to contest the obligation to  pay  and  so
long as the Bank's interest in the Collateral is not jeopardized.

      Section 11.6.  Performance of Loan Documents.  The Borrower
and  the Guarantor shall duly and punctually pay and perform each

and  substances, and pay immediately when due the cost of removal

free  of  any  lien  imposed pursuant to any  such  laws,  rules,
regulations or orders.

      The  Borrower  shall give notice to the  Bank  as  soon  as
reasonably possible and in no event more than five (5) days after
it  receives  any compliance orders, environmental citations,  or
other  notices  from  any  governmental entity  relating  to  any
environmental condition relating to its properties  or  elsewhere
for   which  it  may  have  legal  responsibility  with  a   full
description  thereof; the Borrower agrees to  take  any  and  all
reasonable  steps, and to perform any and all reasonable  actions
necessary  or  appropriate  to  promptly  comply  with  any  such
citations, compliance orders or Environmental Laws requiring  the
Borrower to remove, treat or dispose of such hazardous materials,
wastes  or  conditions at the sole expense of  the  Borrower,  to
provide  the  Bank with satisfactory evidence of such compliance;
provided,  however, that nothing contained herein shall  preclude
the  Borrower  from  contesting any  such  compliance  orders  or
citations  if  such  contest is made in good  faith,  appropriate
reserves  are  established  for  the  payment  for  the  cost  of
compliance  therewith, and the Bank's security  interest  in  any
such  property affected thereby (or the priority thereof) is  not
jeopardized.

      Regardless of whether any Event of Default hereunder  shall
have  occurred and be continuing, the Borrower (i)  releases  and

administrative  orders,  agency  demand  letters,  costs  of  any
settlement  or  judgment  and  claims  of  any  and  every   kind
whatsoever  which  may now or in the future  (whether  before  or
after  the  termination of this Agreement) be paid, incurred,  or
suffered by, or asserted against the Bank by any person or entity
or  governmental agency for, with respect to, or as a  direct  or
indirect  result  of, the presence on or under,  or  the  escape,
seepage, leakage, spillage, discharge, emission, or release  from
or  onto the property of the Borrower of any hazardous materials,
wastes  or  conditions  regulated  by  any  Environmental   Laws,
contamination  resulting  therefrom,  or  arising  out   of,   or
resulting  from, the environmental condition of such property  or

materials (including, without limitation, CERCLA or any so called
federal,  state  or  local "super fund"  or  "super  lien"  laws,
statute,  ordinance,  code, rule, regulation,  order  or  decree)
regardless  of whether or not caused by or within the control  of
the  Bank (the costs and/or liabilities described in (i) and (ii)

covenants  and indemnities contained in this Section  11.7  shall
survive termination of this Agreement.

      Section  11.8.  Further Assurances.  The Borrower  and  the
Guarantor  will, at any time and from time to time,  execute  and
deliver such further instruments and take such further action  as

     (c)  The  Borrower  shall  at  all  times  maintain  working
          capital  (on  a  consolidated basis)  of  greater  than
          $1,000,000.00.   For  the  purposes  hereof,   "working
          capital"  shall mean total consolidated current  assets
          (including   availability  under  the  Revolving   Loan
          Commitment)    less    total    consolidated    current
          liabilities.

       Section  11.14.   Dominion  Account.   The  Borrower   has
established  a lockbox with the Bank into which all  proceeds  of
Receivables of the Borrower shall be remitted.  The Borrower will

          act  or law, or under any other insolvency act or  law,
          now  or  hereafter  existing,  or  any  action  by  the
          Borrower  or either Guarantor consenting to,  approving

          Guarantor for all or a substantial part of the property
          of  any  such  Person; the making by  the  Borrower  or
          either  Guarantor, of an assignment for the benefit  of
          creditors;  the  inability of the  Borrower  or  either
          Guarantor  or the admission by the Borrower  or  either
          Guarantor in writing, of its inability to pay its debts
          as  they  mature  (the  term "acquiescence"  means  the
          failure  to file a petition or motion in opposition  to
          such  petition or proceeding or to vacate or  discharge
          any  order,  judgment  or  decree  providing  for  such
          appointment   within   sixty  (60)   days   after   the
          appointment of a receiver or trustee); or
          
     (b)  Filing  of an involuntary petition against the Borrower
          or   either   Guarantor   in  bankruptcy   or   seeking
          reorganization, arrangement, readjustment of its  debts
          or for any other relief under any applicable bankruptcy
          act  or law, or under any other insolvency act or  law,
          now  or  hereafter  existing and such petition  remains
          undismissed  or unanswered for a period of  sixty  (60)
          days from such filing; or the insolvency appointment of
          a  receiver  or  trustee  of  the  Borrower  or  either
          Guarantor for all or a substantial part of the property
          of  such  Person and such appointment remains unvacated
          or  unopposed for a period of sixty (60) days from such
          appointment, execution or similar process  against  any
          substantial  part of the property of  the  Borrower  or
          either  Guarantor and such warrant remains unbonded  or
          undismissed for a period of sixty (60) days from notice
          to the Borrower or either Guarantor of its issuance.
          
       Dissolution  Proceedings.   Should  proceedings  for   the
dissolution  or  appointment of a liquidator of the  Borrower  or
either Guarantor be commenced.

with respect to either the Borrower or the Guarantor occur at any
time and not be cured within ten days of the occurrence thereof.

      Upon the occurrence of an Event of Default, all Commitments
of  the  Bank  under  this Agreement will  terminate  immediately
(including  any  obligation to make any further  Revolving  Loans
and/or Acquisition Loans, to issue any further Credits to or  for
the  account of any Borrower or to fund the Term Loan),  and,  at
the Bank's option, the Notes and all Indebtedness of the Borrower
will  become immediately due and payable, all without  notice  of
any  kind  to the Borrower or the Guarantor, except that  in  the
case of type described in the "Insolvency" subsection above, such
acceleration shall be automatic and not optional.

      Upon  the occurrence of an Event of Default, the  Bank  may
proceed  to  realize upon the Collateral under the terms  of  the
Collateral Documents and exercise any other rights which  it  has
by law or contract (which rights shall be cumulative in nature).

     Section 13.2.  Waivers.  Except as otherwise provided for in
this  Agreement  and  by applicable law,  the  Borrower  and  the
Guarantor waive (i) presentment, demand and protest and notice of
presentment, dishonor, notice of intent to accelerate, notice  of
acceleration,  protest, default, nonpayment,  maturity,  release,
compromise,  settlement,  extension or  renewal  of  any  or  all
commercial   paper,   accounts,   contract   rights,   documents,
instruments, chattel paper and guaranties at any time held by the
Bank  on  which the Borrower or the Guarantor may in any  way  be
liable and hereby ratify and confirm whatever the Bank may do  in
this regard, (ii) all rights to notice and a hearing prior to the
Bank's taking possession or control of, or to the Bank's replevy,
attachment  or levy upon, the Collateral or any bond or  security
which  might be required by any court prior to allowing the  Bank
to  exercise  any of its remedies, and (iii) the benefit  of  all
valuation,  appraisal and exemption laws.  The Borrower  and  the
Guarantor  acknowledge that they have been advised by counsel  of
their choice with respect to this Agreement, the other Collateral
Documents,  and the transactions evidenced by this Agreement  and
other Collateral Documents.
