                    GRANT GEOPHYSICAL, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

                    ________________________________________


1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

                 The balance sheet of Grant Geophysical, Inc. and subsidiaries
     (the "Company") as of March 31, 1996, and the related statements of
     operations and cash flows for the three months ended March 31, 1996 and
     1995 are unaudited.  The consolidated financial statements should be read
     in conjunction with the audited financial statements and footnotes for the
     year ended December 31, 1995, included in the Company's Form 10-K, as
     filed with the Securities and Exchange Commission.

                 In the opinion of management, the unaudited consolidated
     financial statements include normal recurring adjustments considered
     necessary to present fairly the Company's consolidated financial position
     and results of operations for the periods presented.  The Company's
     operating results for any particular interim period may not be indicative
     of results for a full year.

     Reclassifications

                 Certain amounts previously reported have been reclassified in 
     order to ensure comparability between the periods reported.

     Use of Estimates

                 The preparation of financial statements in conformity with
     Generally Accepted Accounting Principles requires management to make
     estimates and assumptions that affect the reported amounts of assets and
     liabilities and disclosure of contingent assets and liabilities at the
     date of the financial statements and the reported amounts of revenues and
     expenses during the reporting period.  Actual results could differ from
     those estimates.

     Income (Loss) Per Common Share

                 Income (loss) per common share is computed based upon the
     weighted average number of common shares outstanding during the period.
     For purposes of this calculation, outstanding stock options and warrants
     are considered common stock equivalents.  Fully diluted income (loss) per
     common share is determined based upon the weighted average number of
     common shares, calculated using the ending market price of the common
     shares for the period.  The income/loss is decreased/increased by
     undeclared, unpaid cumulative preferred stock dividends in calculating net
     income/loss attributable to the common shareholder.

2.   LIQUIDITY

                 The Company continues to experience constrained liquidity.  The
     factors driving these constraints are a result of the growth curve the
     Company has undertaken which requires substantial immediate cash outflow
     for startups, crew mobilizations and capital expenditures which are paid
     in cash.  Additional cash constraints are being experienced in the first
     and second quarter of 1996 as North American crews have been hampered by
     repetitive adverse weather conditions and permitting delays and some Latin
     American crews have not been able to obtain in a timely manner additional
     equipment in order to perform contracted work efficiently.

                 Management anticipates that the Company will be able to 
     generate sufficient cash flow from operations over the balance of 1996 to 
     fulfill most cash requirements; however, this cannot be completely 
     assured to occur on a timely basis.  In case of a continued short fall in 
     cash, the Company may undertake additional funding from external sources. 
     The cost of these funds may be higher than typical lending rates due to the
     Company's current outstanding debt structure.  Issuance of additional
     equity will be considered as well.

3.   SIGNIFICANT GROUP CONCENTRATION OF CREDIT RISK

                 As of March 31, 1996, the Company had approximately $3,737,000
     in net receivables from Nigerian customers.  Historically, collection of
     payments from Nigerian customers have exceeded the Company's average
     collection period.  Since mid-1993, the Company has encountered additional
     delays in receiving cash remittances from its Nigerian customers due to
     the political and social turmoil experienced in that country.  The Company
     has received several cash payments from its Nigerian customers during the
     first quarter of 1996 and indications are that payments will continue;
     however, Management cannot predict the exact timing and magnitude of such
     payments.

     obligations of the Company at March 31, 1996 and December 31, 1995 follows

                 On July 28, 1994, the Company entered into a $3,000,000 credit
       facility with a holder of the Company's $2.4375 preferred stock.  The
       credit facility was secured by certain foreign receivables. On April 17,
       1995, the credit facility was amended to provide the Company with a
       $1,000,000 short-term credit facility for substantially the same terms
       and conditions.  In June 1995, the short-term credit facility was
       increased by $750,000 and the expiration date was succeedingly extended
       to February 20, 1996.  The entire loan of $1,750,000 plus accrued
       interest was repaid on the expiration date.

                 As of April 26, 1993, the Company entered into a $12,000,000
       revolving credit facility (the "Credit Facility") with a credit
       corporation.  The Credit Facility is secured by domestic and certain
       foreign U.S. dollar denominated accounts receivable, a first lien on
       all unencumbered assets of the Company and a second lien on all other
       assets as available.  The terms of the Credit Facility permit the
       Company to borrow up to the sum of (A) 80% of eligible domestic accounts
       receivable; (B) 65% to 80% of eligible insured international accounts
       receivable (not to exceed $8,000,000); (C) 45% of eligible uninsured
       international accounts receivable; and (D) 10% of eligible other
       accounts receivable.  Nigerian U.S. dollar receivables are not eligible
       under the terms of the Credit Facility.  As of March 31, 1996,
       approximately $3,800,000 had been borrowed and no letters of credit had
       been issued under the Credit Facility.  The term of the Credit Facility
       is three years with an option to terminate at its annual anniversary
       date with at least 90 days notice by either party.  The Credit Facility
       has been extended through February 17, 1997.  The Credit Facility
       contains a number of affirmative and negative covenants, the most
       restrictive of which are financial covenants which require maintenance
       of:  (i) a minimum current ratio; (ii) a maximum ratio of debt to
       tangible net worth; (iii) a minimum level of tangible net worth and (iv)
       a minimum level of working

       capital.  At March 31, 1996, the Company was in compliance with the
       financial covenants contained in the Credit Facility.

                 On February 20, 1996, the Company entered into a two-year term
       loan agreement with a subordinated lender for $3,843,750.  The term loan
       principal is payable beginning March 1, 1997 in eleven equal monthly
       installments of $64,063 and a final installment of $3,139,063 due on
       February 20, 1998.  A mandatory prepayment provision requires the
       Company to prepay the outstanding term loan balance with 50% of all U.S.
       Dollar payments made on the Nigerian accounts receivable balance as of
       February 20, 1996.  The term loan bears interest at 14% per annum
       payable monthly beginning on March 1, 1996.  The Company paid a
       non-refundable loan fee of $93,750 and is subject to a quarterly
       administration fee of $75,000 commencing August 1996.  The term loan
       contains a number of affirmative and negative covenants, the most
       restrictive of which are financial covenants which require maintenance
       of:  (i) a minimum current ratio; (ii) a maximum ratio of debt to
       tangible net worth; (iii) a minimum level of tangible net worth and (iv)
       a minimum level of working capital.  At March 31, 1996, the Company was
       in compliance with the financial covenants contained in the term loan.

                 On March 27, 1996, the Company issued $3,000,000 of its 8%
       Convertible Debentures ("Debentures") due December 31, 1999.  The
       Debentures are convertible, at the option of the purchaser, into shares
       of the Company's Common Stock at a conversion price of 80% of the five
       day average low trading price prior to the conversion election of the
       Common Stock, provided that such 80% figure is increased to 100% if the
       Debentures are converted within 45 days of the Closing Date.  Under
       certain circumstances, the Company can redeem Debentures submitted for
       conversion at 120% of the par value of the Debentures. Additionally, the
       Company may redeem the Debentures on or after March 27, 1997 at a rate
       of 120% of the par value of the Debenture, and on or after March 27,
       1999, at a rate of 100% of the par value.  Interest of 8% per annum is
       payable quarterly.

                 At March 31, 1996, the Company was in default of certain
       covenants related to delays in payment on its equipment notes payable.
       Payment acceleration of these equipment notes was waived by the
       Company's creditors.

5.     PREFERRED STOCK ISSUANCE

                 On March 20, 1996, the Company issued 143,000 shares of the
       Company's $2.4375 Convertible Exchangeable Preferred Stock (the "$2.4375
       Preferred Stock").  The purchaser of the $2.4375 Preferred Stock is
       entitled to all unpaid, undeclared dividends in arrears through March
       31, 1996 totaling $1,220,000.  The net proceeds from the issuance was
       $1,573,000.  The cumulative adjustment for these prior unpaid,
       undeclared dividends is shown in the first quarter results.

6.     DIVIDENDS IN ARREARS

                 The quarterly dividend payments for the first quarter 1996,
       the four quarters of 1995, 1994 and 1993 and one quarterly dividend
       payment for 1992 on the $2.4375 Preferred Stock were deferred by the
       Company's Board of Directors.  As of March 31, 1996, $2.4375 Preferred
       Stock dividends in arrears amounted to approximately $19,622,000.  This
       amount relates to the total of 2,300,000 shares now outstanding.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS

        The following discussion of the historical financial condition and
results of operations of the Company should be read in conjunction with the
financial statements and notes thereto, included elsewhere in this Form 10-Q.

RESULTS OF OPERATIONS

        The Company's operating profitability is dependent upon the mix of
contracts in effect during any given period.

        Three months ended March 31, 1996 compared to three months ended March
31, 1995

        The Company's consolidated revenues increased 51% ($9,402,000) to
$27,808,000.  This increase is primarily due to increased crew capacity and crew
months in Latin America and the Far East, partially reduced by decreased
activity in Nigeria.
 
        Revenues from the United States operations increased 14% ($1,557,000) to
$12,656,000.  The United States operations, hampered somewhat by repetitive
adverse weather conditions in the first quarter and permitting delays, included
$1,200,000 of revenues resulting from a sale of the Company's interests under
two specific revenue sharing agreements.  The impact of this transaction on
operating income was $1,098,359.  Transactions of this nature may occur on a
periodic basis as the company continues to grow and is able to capitalize on
such opportunities.  Crew capacity in the United States was increased to seven
crews from six crews in the prior year with the introduction of a Telseis
instrument shallow water transition zone crew. This crew had previously operated
in the Company's Middle East operations in 1993 and 1994.  The crew resumed
contracted work in mid-March of 1996.  Also, the United States operations added
an Input/Output System II in the second quarter of 1995 that replaced an older
technology system that was retired after the first quarter of 1995. Total crew
months for the United States in the 1996 period were sixteen as compared to
eighteen for the same period last year.  The region has contracted work for most
of its crews through the third quarter of 1996 with some crews contracted for
the balance of the year.

        Revenues from international operations increased 107% ($7,845,000) to
$15,152,000.  This increase is largely due to both increased crew capacity and
active crew months in Latin America.  The Nigerian operations experienced
reduced crew months and revenues compared to last year since the majority of the
region's contracted work was completed in early fourth quarter of 1995. The Far
East experienced increased crew months and revenues as two crews were active for
a portion of the first quarter.  The Middle East region had no activity as
compared to last year when there were minimal revenues from equipment rentals
during the time the region was being demobilized.

        Latin America revenues increased 286% ($9,859,000) to $13,306,000.  The
number of active crews increased to seven in 1996 as compared to four in the
prior year, and active crew months increased to fifteen from seven,
respectively.  During this period, the Company operated one crew in Bolivia, two
crews in Colombia, three crews in Peru, and began the start-up and mobilization
of a new Input/Output System II 3D crew in Brazil where the Company had
previously operated a smaller 2D crew under contract for three years.  In the
prior year's period the Company operated one crew in Brazil, two crews in
Colombia, and one crew in Peru with a second crew being mobilized late in the
quarter.  The region generally has contracted backlog extending into the latter
part of the year with some backlog in Brazil extending into early 1998.

        Nigerian revenues decreased 72% ($2,357,000) to $938,000.  The number of
active crews has decreased to one in 1996 from three in 1995 and the number of
active crew months decreased from seven to three, respectively. This decrease is
due to the completion during the fourth quarter of 1995 of contracted work for
two crews.  The third crew has now completed its contracted work in March of
1996.  The region currently has no contracted work in backlog, but the Company
has several bids currently outstanding, and current expectations are that the
Company will be awarded at least one of these contracts.  The Company is
currently preparing for this anticipated work and is actively marketing its
services in the region; however, there is no assurance that the Company will be
awarded any of such work.




                                      11
<PAGE>   12

        Revenues in the Far East increased 179% ($582,000) to $908,000 with
active crew months increasing to three from one in this period as compared to
last year.  The crew in Bangladesh, which was temporarily suspended due to
political unrest in the region, has now resumed operations and the contracted
work as been expanded.  The second crew operated in Indonesia in January and is
currently not in operation.

        Direct operating expenses as a percentage of revenue increased to 80%
from 76%.  The increase is a result of higher operating costs in the United
States from adverse weather conditions and permitting delays and equipment
delays to Latin America which did not allow some crews to operate efficiently. 
The overall dollar increase is primarily due to increased seismic activity in
Latin America and the United States with a partial reduction resulting from
decreased activity in Nigeria.

        Other operating expenses, which consist of general and administrative
expenses at corporate headquarters and in foreign locations, decreased slightly
as a percentage of revenues to 8% from 10%.  The percentage decrease was due to
the Company's ability to generate 51% more revenues, primarily in Latin America,
while incurring approximately the same amount of other operating expenses.  The
overall increase in the amount of other operating expenses can be attributed
primarily to the higher level of seismic crew activity in Latin America and the
United States.

        Depreciation and amortization expense decreased only slightly to
$2,370,000 from the prior year as the majority of newly acquired assets during
1995 have begun to be depreciated.  As the Company continues to purchase and
utilize new seismic acquisition systems, the depreciation and amortization
expense should increase.

        Interest expense increased from prior year by 83% to $1,330,000 as the
Company experienced higher levels of financing at higher interest rates,
particularly in the foreign areas of operation.

        Other income (deduction) decreased approximately $441,000 from the first
quarter 1995.  Foreign currency translation gains of approximately $284,000
resulting from the fluctuation in the Nigerian Naira and a $152,000 gain from
the sale of idle equipment recorded during the first quarter of 1995 were not
duplicated in 1996.

        The income tax provision in both periods consisted of taxes owed to
foreign countries based on local tax laws. The level of foreign taxes has
increased from the prior period due to the increased activity of international
operations.  No provision for U.S. Federal income taxes was made in either
period as the Company currently has net operating losses available for
carryforward.

LIQUIDITY AND CAPITAL RESOURCES

        Liquidity.  The Company's short-term and long-term liquidity position
remains restricted.  As of May 10, 1996, the Company's level of available cash
was approximately $1,304,000 as compared to the December 31, 1995 balance of
approximately $1,047,000.  Net cash provided by operating activities during the
first quarter 1996 was approximately $546,000 compared to approximately
$1,458,000 for the same period in 1995. The primary factors influencing this
liquidity issue are the (i) increases in cash outflows for startups and crew
mobilizations; (ii) increases in the level of capital expenditures which are not
financed that are required to keep pace with the growth in the United States and
Latin American markets; (iii) the level at investment required for the 
Company's proprietary seismic data acquisition system; and (iv) the continued
delays in receiving cash remittances from Nigeria and a certain domestic
customer.  Additional cash constraints were experienced in the first and second
quarter of 1996 as North American crews have been hampered by repetitive adverse
weather conditions and permitting delays and some Latin American crews were not
able to obtain additional equipment timely in order to perform contracted work
efficiently.

        Since mid-1993, the Company has encountered additional delays in
receiving cash remittances from its Nigerian customers due to the political and
social turmoil experienced in that country.  During the first quarter of 1995,
these delays increased. These delays caused the Company to intensify its
collection efforts. The net receivable balance from Nigerian customers has
decreased from $7,896,000 at December 31, 1994 to $2,970,000 at April 30, 1996 
due primarily to increased collection efforts and reduced crew operations.
There have been cash payments received during the first quarter of 1996, and
indications are that payments will continue; however, management cannot predict
the exact timing and magnitude of such payments.  Also, during the second 
quarter of 1995, the Company was




                                      12

<PAGE>   13

notified by one of its domestic customers that payment on services performed
primarily during the first quarter of 1995 would be delayed.  Payments totaling
approximately $588,000 have been received through May 10, 1996.  The Company
believes the receivable balance at May 10, 1996 of $1,723,000 should be
collectible.

        The Company has a revolving credit facility with its principal lender, a
credit corporation, for $12,000,000, secured by domestic and certain foreign
U.S. dollar denominated accounts receivable other than those originating from
Nigerian customers, a first lien on all unencumbered assets of the Company and a
second lien on all other assets as available.  The Company entered into this
credit facility on February 17, 1993 for the portion secured by the domestic
receivables and on April 26, 1993 for the portion secured by the foreign U.S.
dollar denominated receivables.  The credit facility has been extended through
February 17, 1997.  As of March 31, 1996 approximately $3,800,000 had been
borrowed and no letters of credit had been issued under the credit facility. The
terms of the agreement permit the Company to borrow up to the sum of (A) 80% of
its eligible United States accounts receivable; (B) 65% to 80% of the eligible
insured international accounts receivable (not to exceed $8,000,000); (C) 45% of
the eligible uninsured international accounts receivable; and (D) 10% of
eligible other accounts receivable.  The credit facility contains a number of
affirmative and negative covenants, the most restrictive of which are financial
covenants which require maintenance of: (i) a minimum current ratio; (ii) a
maximum ratio of debt to tangible net worth; (iii) a minimum level of tangible
net worth and (iv) a minimum level of working capital.  Subsequent to December
31, 1994, an amendment to the Credit Facility was executed, which principally
provided additional flexibility with respect to certain covenants. At March 31,
1996, the Company was in compliance with the covenants.  At May 10, 1996,
approximately $6,457,000 had been borrowed under this credit facility.  All of
the Company's eligible accounts receivable are currently pledged to secure this
line of credit and the Company's current level of cash represents amounts
borrowed under the credit facility.

        On March 1, 1995, the Company entered into a long-term financing
agreement with a credit company for $5,000,000. The facility contains a bargain
purchase option at the end of the lease term and is secured by the leased
equipment. At May 10, 1996, the Company had borrowed approximately $4,352,000
under the facility for equipment purchases.  At March 31, 1996, the Company was
in default of certain covenants for this and other financing agreements related
to delays in payment on its equipment notes payable.  Payment acceleration of
these equipment notes was waived by the Company's creditors.

        On February 20, 1996, the Company entered into a two-year term loan
agreement with a subordinated lender for $3,843,750.  The term loan principal is
payable beginning March 1, 1997 in eleven equal monthly installments of $64,063
and a final installment of $3,139,063 due on February 20, 1998.  A mandatory
prepayment provision requires the Company to prepay the outstanding term loan
balance with 50% of all U.S. Dollar payments made on the Nigerian accounts
receivable balance as of February 20, 1996.  The term loan bears interest at 14%
per annum payable monthly beginning on March 1, 1996.  The Company paid a
non-refundable loan fee of $93,750 and is subject to a quarterly administration
fee of $75,000 commencing August 1996.  The term loan contains a number of
affirmative and negative covenants, the most restrictive of which are financial
covenants which require maintenance of:  (i) a minimum current ratio; (ii) a
maximum ratio of debt to tangible net worth; (iii) a minimum level of tangible
net worth and (iv) a minimum level of working capital.  At March 31, 1996, the
Company was in compliance with the covenants.

        On March 20, 1996, the Company issued 143,000 shares of the Company's
$2.4375 Convertible Exchangeable Preferred Stock.  The purchaser of the
Preferred Stock is entitled to all undeclared, unpaid dividends in arrears
through March 20, 1996.  The net proceeds from the issuance was $1,573,000.
Additionally on March 27, 1996, the Company issued $3,000,000 of its 8%
Convertible Debentures ("Debentures") due December 31, 1999.   The Debentures
are convertible, at the option of the purchaser, into shares of the Company's
Common Stock at a conversion price of 80% of the five day average low trading
price prior to the conversion election of the Common Stock, provided that such
80% figure is increased to 100% if the Debentures are converted within 45 days
of the Closing Date.  Under certain circumstances, the Company can redeem
Debentures submitted for conversion at 120% of the par value of the Debentures.
Additionally, the Company may redeem the Debentures on or after March 27, 1997
at a rate of 120% of the par value of the Debentures, and on or after March 27,
1999, at a rate of 100% of the par value.  Interest of 8% per annum is payable
quarterly.

        While the financing transactions entered into in the first quarter of
1996 provided funding for certain obligations, the Company continues to
experience constrained liquidity.  The Company will continue to consider
additional sources of working capital to help improve its liquidity position. 
Management anticipates that the Company will be able to generate sufficient cash
flow from operations over the balance of 1996 to fulfill most of




                                      13

its cash requirements; however, this cannot be completely assured to occur on a
timely basis.  In case of a continued short fall in cash, the Company may
undertake additional funding from external sources.  The cost of these funds may
be higher than typical lending rates due to the Company's current outstanding
debt structure. Issuance of additional equity will be considered as well.

        As a result of the continued short-term liquidity situation, the Company
has elected to defer the fourteenth quarterly dividend payment for March 31,
1996 on the $2.4375 preferred stock.  See Note 6 of Notes to Consolidated
Financial Statements.

        Capital Expenditures.  Capital expenditures were approximately
$9,365,000 and $3,484,000 for the quarters ended March 31, 1996 and 1995,
respectively. The expenditures in the first quarter of 1996 were for the
purchase of one complete seismic acquisition recording system and additional
equipment necessitated by the Company's increased seismic operations in Latin
America and the United States and other equipment necessary for the completion
of the Company's new seismic data acquisition system.  The majority of these
purchases are being financed utilizing leases and long-term notes payable from a
credit corporation and equipment manufacturers.

        The Company is currently assembling a new proprietary seismic data
acquisition system.  This system is a radio frequency telemetry system
specifically designed to be used on large 3D surveys where cables are
undesirable. The Company plans to complete the deployment phase of the first
system during the second quarter of 1996. Currently, there are no plans to
market or sell this technology to any third parties.

        The Company's capital expenditures for the remainder of 1996, which are
estimated at amounts similar to the prior year, are contingent on the Company's
ability to obtain short- and long-term financing and on the generation of
sufficient cash flows from operations.

        Long-Term Obligations.  The long-term obligations of the Company as of
March 31, 1996 consisted primarily of the 8% Convertible Debentures, notes
payable and capital lease obligations related to the acquisition of geophysical
equipment and the Corporate headquarters and notes payable to the former Tensor
shareholders related to the Settlement and Release Agreement effective January
1, 1994.

OTHER

        Foreign Exchange Gains and Losses.  In order to mitigate foreign
exchange rate fluctuations, the Company attempts to structure the majority of
its international contracts to be billed and paid at a certain U.S. Dollar rate.
Additionally, the Company enters into same currency debt of a foreign subsidiary
to pay expenses incurred locally.  Foreign currency transaction/translation
gains and losses resulting from these arrangements are included in Other income.
Presently, the Company does not use derivatives or forward foreign exchange
hedging contracts.

a rate per annum equal to the Post-Default Rate.

                          (c)     Interest Payment. Interest on the Loan shall
be payable monthly, in arrears, on the first day of each month for the

                      MANAGEMENT, COLLECTION AND STATUS OF
                    ACCOUNTS RECEIVABLE AND OTHER COLLATERAL

                 SECTION 7.01.    Collection of Receivables; Management of
Collateral.  (a)  So long as any principal of or interest on the Loan shall
remain unpaid or the Lender shall have any Commitment hereunder, the Borrower
shall continue to maintain the Lock-Box Accounts.  The Borrower hereby pledges,
assigns and grants to the Lender a continuing security interest in the Lock-Box
Accounts and all funds held in such accounts, all certificates and instruments,
if any, from time to time evidencing such accounts, all notes, checks and other
instruments from time to time deposited in such accounts, all interest, if any,
from time to time received in respect of such accounts and all other property
of the Borrower, from time to time in the possession of, under the control of,
or in transit to, the Senior Secured Creditor or the Lender.  The Borrower
shall transfer to the Lender the exclusive dominion and control of the TCB
Lock-Box Account, and the Borrower shall transfer to the Lender, as soon as
the Senior Debt is no longer outstanding, the exclusive dominion and control of
the FIT Lock-Box Account and the Borrower shall have no right of withdrawal
from such accounts; provided, however that in the absence of an Event of
Default, the Lender will cause to be remitted fifty percent (50%) of the
proceeds of the TCB Lock-Box Account to the FIT Lock-Box Account and, while the
Lender has control of the FIT Lock-Box Account, the Lender will remit all of
the proceeds of the FIT Lock-Box Account to the Borrower for use in the
ordinary course of Borrower's business.  Promptly after the Effective Date, and
from time to time thereafter as any additional Account Debtor shall have become
obligated to the Borrower with respect to Nigerian Accounts Receivable, the
Borrower, at its sole expense, shall send notice to each such Account Debtor
stating that all payments by such Account Debtor shall be made directly to the
Central Bank of Nigeria, with instructions for the Central Bank of Nigeria to
make all payments in U.S. Dollars directly to the TCB Lock-Box Account;
provided, that such notice may be included in an invoice sent by the Borrower
to such Account Debtor.  The Borrower shall provide to the Lender a copy of
each such notice that is sent to any Account Debtor with respect to Nigerian
Accounts Receivable.  Except as otherwise expressly provided to the contrary in
this Agreement and the Loan Documents, the Borrower shall take all such actions
as the Lender deems necessary or appropriate to ensure that at all times on and
after the Effective Date all proceeds of Nigerian Assets (as defined in the
Intercreditor Agreement) owned by the Borrower are deposited directly in the
TCB Lock-Box Account and all proceeds of Collateral, other than Nigerian Assets
(as defined in the Intercreditor





                                      -33-
<PAGE>   39

Agreement) owned by the Borrower are deposited directly in the TCB Lock-Box
Account and all proceeds of Collateral, other than Nigerian Assets (as defined
in the Intercreditor Agreement), owned by the Borrower are deposited directly 
in the FIT Lock-Box Account.  If, notwithstanding the notices and actions
provided for in the preceding sentences of this Section 7.01(a), the Borrower
shall receive or any financial institution shall receive for the account of the
Borrower, any proceeds of Collateral, the Borrower shall, or shall cause such
financial institution to, transmit in the form received, before the close of
business on the next succeeding Business Day, all such proceeds (properly
endorsed, where required, so that all items delivered shall be collected by the
Lender) to the Lender for credit to the Loan Account, in accordance with this
Agreement, if such proceeds are proceeds of Nigerian Assets (as defined in the
Intercreditor Agreement) and, if such proceeds are proceeds of Collateral other
than Nigerian Assets (as defined in the Intercreditor Agreement), to the Senior
Secured Creditor if the Senior Debt is outstanding or, if the Senior Debt is not
outstanding, to the Lender.  The Borrower shall not, and shall cause any such
financial institution not to, commingle any such proceeds so received with the
Borrower's other property, and shall hold separate and apart from all other
property, all such proceeds in an express trust for the benefit of the Senior
Secured Creditor and the Lender until delivery thereof is made to the Senior
Secured Creditor or the Lender.  The Borrower hereby agrees not to deposit any
monies into the Lock-Box Accounts or to otherwise permit any moneys to be
deposited into such accounts or commingled with other funds in such accounts,
except proceeds of the Accounts Receivable and other Collateral owned by the
Borrower.

                 After an Event of Default, the Lender may, subject to the
provisions of the Intercreditor Agreement, send a notice of assignment and/or
notice of the Lender's security interest to any and all Account Debtors or any
third party holding or otherwise concerned with any of the Collateral, and
thereafter the Lender shall have the sole right, provided the Senior Debt is
not outstanding, or, if the Senior Debt is outstanding, subject to the
provisions of the Intercreditor Agreement, the Lender and the Senior Secured
Creditor shall both have the right to collect the Accounts Receivable, and/or
take possession of the Collateral and the books and records relating thereto.
The Borrower shall not without prior written consent of the Lender, grant any
extension of time of payment of any Account Receivable, compromise or settle
any Account Receivable for less than the full amount thereof, release, in whole
or in part, any Person or property liable for the payment thereof, or allow any
credit or discount whatsoever thereon, except, prior to the occurrence of an
Event of Default, as permitted by Section 6.02(j) hereof.

                          (b)     (i)      Subject to the provisions of the
Intercreditor Agreement, the Borrower hereby constitutes the Lender or its
designee on behalf of the Lender as such Borrower's attorney-in-fact with power
to endorse the Borrower's name upon any notes, acceptances, checks, drafts,
money orders or other evidences of payment or Collateral that may come into its
possession, to sign the Borrower's name on any invoice or bill of lading
relating to any of the Accounts Receivable, drafts against Account Debtors,
assignments and verifications of Accounts Receivable and notices to Account
Debtors, to send verification of Accounts Receivable, and upon the acceleration
of the Loan, and any other Obligations under the Loan Documents following an
Event of Default, to notify the Postal Service authorities to change the
address for delivery of mail addressed to such Borrower to such address as the
Lender may designate and to do all other acts and things necessary to carry out
this Agreement.  All acts of





                                      -34-
<PAGE>   40
said attorney or designee are hereby ratified and approved, and said attorney
or designate shall not be liable for any acts of omission or commission (other
than acts or omissions constituting gross negligence or willful misconduct),
nor for any error of judgment or mistake of fact or law; this power being
coupled with an interest is irrevocable until the Loan, and any other
Obligations under the Loan Documents are paid in full and all of the Loan
Documents are terminated.

                                  (ii)     Subject to the provisions of the
Intercreditor Agreement, the Lender, without notice to or consent of the
Borrower, upon the occurrence and during the continuance of an Event of Default
(A) may sue upon or otherwise collect, extend the time of payment of, or
compromise or settle for cash, credit or otherwise upon any terms, any of the
Accounts Receivable or any securities, instruments or insurance applicable
thereto and/or release the Account Debtor thereon; (B) is authorized and
empowered to accept the return of the goods represented by any of the Accounts
Receivable and (C) shall have the right to receive, endorse, assign and/or
deliver in its name or the name of the Borrower any and all checks, drafts, and
other instruments or the payment of money relating to the Accounts Receivable.
The Borrower hereby waives notice of presentment, protest and non-payment of
any instrument so endorsed, all in a commercially reasonable manner and without
discharging or in any way affecting liability hereunder.

                          (c)     Nothing herein contained shall be construed
to constitute the Borrower as agent of the Lender for any purpose whatsoever,
and the Lender shall not be responsible or liable for any shortage,
discrepancy, damage, loss or destruction of any part of the Collateral wherever
the same may be located and regardless of the cause thereof (other than from
acts or omissions of the Lender constituting gross negligence or willful
misconduct).  The Lender shall not, under any circumstances or in any event
whatsoever, have any liability for any error or omission or delay of any kind
occurring in the settlement, collection or payment of any of the Accounts
Receivable or any instrument received in payment thereof or for any damage
resulting therefrom (other than acts or omissions of the Lender constituting
gross negligence or willful misconduct).  The Lender, by anything herein or in
any assignment or otherwise, does not assume any of the obligations of the
Borrower under any contract or agreement assigned to the Lender, and the Lender
shall not be responsible in any way for the performance by the Borrower of any
of the terms and conditions thereof.

                          (d)     If any of the Accounts Receivable includes a
charge for any tax payable to any Governmental Authority, the Lender is hereby
authorized (but in no event obligated) in its discretion to pay the amount
thereof to the proper taxing authority for the account of the Borrower and to
add such amount to the Loan.  The Borrower shall notify the Lender if any
Accounts Receivable include any taxes due to any such authority and, in the
absence of such notice, the Lender shall have the right to retain the full
proceeds of such Account Receivable and shall not be liable for any taxes that
may be due from the Borrower by reason of the sale and delivery creating such
Accounts Receivable.

                 SECTION 7.02.    Accounts Receivable Documentation.  The
Borrower will at such intervals as the Lender may require, execute and deliver
confirmatory written assignments of the Nigerian Accounts Receivable (and,
after the repayment in full of the Senior Debt, all

<PAGE>   41

and copies of original shipping or delivery receipts for all merchandise sold.
In addition, the Borrower shall notify the Lender of any non-compliance in

7.03 below.  The items to be provided under this Section 7.02 are to be in form
satisfactory to the Lender and are to be executed and delivered to the Lender
from time to time solely for its convenience in maintaining records of the
Collateral.  The failure by the Borrower to give any of such items to the
Lender shall not affect, terminate, modify or otherwise limit the Lender's lien
or security interest in the Collateral.  The Borrower shall not re-date any
invoice or sale or make sales on extended dating beyond that customary in the
Borrower's industry, and shall not re-bill any Account Receivable without
promptly disclosing the same to the Lender and providing the Lender with a copy
of such re-billing, identifying the same as such.  If the Borrower becomes
aware of anything materially detrimental to any of the Borrower's customers'
credit, the Borrower will promptly advise the Lender thereof.

                 SECTION 7.03.    Status of Accounts Receivable and Other
Collateral.  With respect to Collateral of the Borrower at the time the
Collateral becomes subject to the Lender's security interests, the Borrower,
covenants, represents and warrants:  (a) the Borrower shall be the sole owner,
free and clear of all liens, mortgages, pledges or other encumbrances except in
the favor of the Lender or otherwise permitted hereunder, of and fully
authorized to sell, transfer, pledge and/or grant a security interest in each
and every item of said Collateral; (b) each Account Receivable shall be a good
and valid account representing an undisputed bona fide indebtedness incurred or

sum as set forth in the invoice relating thereto with respect to any absolute
sale and delivery upon the specified terms of goods sold by the Borrower, or

acceleration of, the maturity of such Indebtedness; or any such Indebtedness in
excess of such amount shall be declared to be due and payable, or required to
be prepaid (other than by a regularly scheduled required prepayment), prior to
the stated maturity thereof;

                          (g)     any Loan Party (i) shall institute any

the English Judicial Judgment dated December 8, 1995, with respect to the
matter of High Life Cruise S.A.E. versus the Borrower shall not be deemed to be
an Event of Default under this Section 8.01(k);

                          (l)     the Borrower or any of its Affiliates shall
have made a complete or partial withdrawal from a Multiemployer Plan, and, as a
result of such complete or partial withdrawal, the Borrower or such Affiliate
incurs a withdrawal liability in an annual amount exceeding $100,000; or a
Multiemployer Plan enters reorganization status under Section 4241 of ERISA,
and, as a result thereof, the Borrower's or such Affiliate's annual
contribution requirement with respect to such Multiemployer Plan increases in
an annual amount exceeding $100,000.

                          (m)     any Termination Event with respect to any

such commitment shall forthwith terminate, (ii) declare the Loan, all interest
thereon and all other amounts payable under this Agreement to be forthwith due

or further notice of any kind, all of which are hereby expressly waived by the
Borrower;





                                      -39-

provided, however, that upon the occurrence of an Event of Default described in
subsections (g) and (h) of this Section 8.01, its commitment to make the Loan
hereunder shall immediately terminate and the Loan, all such interest thereon
and all other amounts shall become payable and be forthwith due and payable,
without presentment, demand, protest or further notice of any kind, all of
which are expressly waived by the Borrower, and (iii) exercise any and all of
its other rights under applicable law, hereunder and under the other Loan

party in a written notice to the other party complying as to delivery with the
terms of this Section 9.01.  All such notices and other communications shall be
effective (i) if mailed, when received or three days after mailing, whichever
first occurs, (ii) if telecopied, when transmitted, provided same is on a
Business Day and, if not, on the next Business Day, or (iii) if delivered, upon
delivery, provided same is on a Business Day and, if not, on the next Business
Day, except that notices to the Lender pursuant to Article II hereof shall not

                 SECTION 9.02.    Amendments, Etc.  No amendment of any
provision of this Agreement, the Note or any other Loan Document shall be
effective unless it is in writing and signed by the Borrower, each of the
Guarantors and the Lender, and no waiver of any provision of this Agreement,
the Note or any other Loan Document, nor consent to any departure by the
Borrower therefrom, shall be effective unless it is in writing and signed by
the Lender, and then such waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given.

                 SECTION 9.03.    No Waiver; Remedies, Etc.  No failure on the
part of the Lender to exercise, and no delay in exercising, any right hereunder
or under any other Loan Document shall operate as a waiver thereof; nor shall
any single or partial exercise of any right under any Loan Document preclude
any other or further exercise thereof or the exercise of any other right.  The
rights and remedies of the Lender provided herein and in the other Loan
Documents are cumulative and are in addition to, and not exclusive of, any
right or remedy provided by law.  The rights of the Lender under any Loan
Document against any party thereto are not conditional or contingent on any
attempt by the Lender to exercise any of its rights under any other Loan
Document against such party or against any other Person.

                 SECTION 9.04.    Fees, Costs, Expenses and Taxes.  Whether or
not the Loan is made hereunder or the transactions contemplated hereby are
consummated, the Borrower will pay on demand (i) all fees, costs and expenses
in connection with the preparation, execution, delivery, filing, recording,
amendment, modification, waiver and administration of the Loan Documents and
the other documents to be delivered pursuant to the Loan Documents, including,
without limitation, the reasonable fees, out-of-pocket expenses and other
client charges of Schulte Roth & Zabel, counsel to the Lender, and with respect
to advising the Lender as to its rights and responsibilities under the Loan
Documents and the reasonable fees, out-of-pocket expenses and other client
charges of all accountants, auditors and consultants retained by the Lender in





                                      -41-
<PAGE>   47
connection with the transactions contemplated by this Agreement, and (ii) all
costs and expenses, if any (including reasonable counsel fees, out-of-pocket
expenses and other client charges), in connection with the enforcement of the
Loan Documents and the other documents to be delivered pursuant to the Loan
Documents.  In addition, the Borrower will pay any and all stamp and other
taxes and fees payable or determined to be payable in connection with the
execution, delivery, filing and recording of the Loan Documents and the other
documents to be delivered pursuant to the Loan Documents, and will save the
Lender harmless from and against any and all liabilities with respect to or
resulting from any delay in paying or omission to pay such taxes and fees.

                 SECTION 9.05.    Right of Set-off.  Upon the occurrence and
during the continuance of any Event of Default, the Lender may, and is hereby
authorized to, at any time and from time to time, without notice to the
Borrower (any such notice being expressly waived by the Borrower) and to the
fullest extent permitted by law, subject to the provisions of the Intercreditor
Agreement set off and apply any and all deposits (general or special, time or
demand, provisional or final) at any time held and other indebtedness at any
time owing by the Lender to or for the credit or the account of the Borrower
against any and all Obligations now or hereafter existing, irrespective of
whether or not the Lender shall have made any demand hereunder or thereunder
and although such Obligations may be contingent or unmatured.  The Lender
agrees to notify the Borrower promptly after any such set-off and application
made by the Lender, provided that the failure to give such notice shall not
affect the validity of such set-off and application.  The rights of the Lender
under this Section 9.05 are in addition to the other rights and remedies
(including, without limitation, other rights of set-off) which the Lender may
have.

                 SECTION 9.06.    Severability.  Any provision of this
Agreement, or of any other Loan Document to which the Borrower or any of the
Guarantors is a party, which is prohibited or unenforceable in any jurisdiction
shall, as to such jurisdiction, be ineffective to the extent of such
prohibition or unenforceability without invalidating the remaining portions
hereof or thereof or affecting the validity or enforceability of such provision
in any other jurisdiction.

                 SECTION 9.07.    Successors and Assigns.  This Agreement shall
be binding upon and inure to the benefit of the Borrower, each Guarantor and
the Lender and their respective successors and assigns, except that neither the
Borrower nor any Guarantor may assign its rights hereunder or any interest
herein without the prior written consent of the Lender.  The Lender may assign
to one or more banks or other entities all or any part of, or may grant
participations to one or more banks or other entities in or to all or any part
of the Commitment, the Loan, or the Note, and, to the extent of any such
assignment or participation (unless otherwise stated therein), the assignee of
such assignment shall have the same rights and benefits hereunder and under the
Note as it would have if it were the Lender hereunder.  The Lender may, in
connection with any such assignment or participation or as may be required by
law or any Governmental Authority or other regulatory body, disclose any public
and non-public information relating to the Borrower and each of the Guarantors
furnished by or on behalf of the Borrower or any of the Guarantors or any of
their Affiliates to the Lender.

                 SECTION 9.08.    Counterparts.  This Agreement may be executed
in any number of counterparts and by different parties hereto in separate
counterparts, each of which





                                      -42-
<PAGE>   48
shall be deemed to be an original, but all of which taken together shall
constitute one and the same agreement.

                 SECTION 9.09.    Headings.  Section headings herein are
included for convenience of reference only and shall not constitute a part of
this Agreement for any other purpose.

                 SECTION 9.10.    Governing Law.  This Agreement, the Note, and
the other Loan Documents shall be governed by, and construed in accordance
with, the law of the State of New York applicable to contracts made and to be
performed in the State of New York without regard to conflicts of law
principles.  Any legal action or proceeding with respect to this Agreement or
any other Loan Document may be brought in the courts of the State of New York
or of the United States for the Southern District of New York, and, by
execution and delivery of this Agreement, the Borrower and each Guarantor
hereby irrevocably accept for themselves in respect of their property,
generally and unconditionally, the jurisdiction of the aforesaid courts.  The
Borrower and each Guarantor further irrevocably consent to the service of
process out of any of the aforementioned courts and in any such action or
proceeding by the mailing of copies thereof by registered or certified mail,
postage prepaid, to the Borrower at its address for notices contained in
Section 9.01, such service to become effective thirty (30) days after such
mailing.  The Borrower and each Guarantor hereby irrevocably appoint the
Secretary of State of the State of New York, or such other Person as shall be
acceptable to the Lender, as their agent for service of process in respect of
any such action or proceeding.  Nothing herein shall affect the right of the
Lender to service of process in any other manner permitted by law or to
commence legal proceedings or otherwise proceed against the Borrower and each
Guarantor in any other jurisdiction.

                 SECTION 9.11.    WAIVER OF JURY TRIAL, ETC.  EACH OF THE
BORROWER, EACH GUARANTOR AND THE LENDER HEREBY WAIVES ANY RIGHT TO A TRIAL BY
JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM CONCERNING ANY RIGHT UNDER THIS
AGREEMENT, THE NOTE, OR OTHER LOAN DOCUMENT, OR UNDER ANY AMENDMENT, WAIVER,
CONSENT, INSTRUMENT, DOCUMENT OR OTHER AGREEMENT DELIVERED OR WHICH IN THE
FUTURE MAY BE DELIVERED IN CONNECTION THEREWITH, OR ARISING FROM ANY BANKING
RELATIONSHIP EXISTING IN CONNECTION WITH THIS AGREEMENT, AND AGREES THAT ANY
SUCH ACTION, PROCEEDINGS OR COUNTERCLAIM SHALL BE TRIED BEFORE A COURT AND NOT
BEFORE A JURY.  EACH OF THE BORROWER AND UGNL HEREBY WAIVES ANY RIGHT IT MAY
HAVE TO CLAIM OR RECOVER IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ANY SPECIAL,
EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES OTHER THAN, OR IN
ADDITION TO, ACTUAL DAMAGES.  THE BORROWER AND UGNL CERTIFY THAT NO OFFICER,
REPRESENTATIVE, AGENT OR ATTORNEY OF THE LENDER HAS REPRESENTED, EXPRESSLY OR
OTHERWISE, THAT THE LENDER WOULD NOT, IN THE EVENT OF ANY ACTION, PROCEEDING OR
COUNTERCLAIM, SEEK TO ENFORCE THE FOREGOING WAIVERS.  THE BORROWER AND UGNL
HEREBY





                                      -43-
<PAGE>   49
ACKNOWLEDGE THAT THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE LENDER
ENTERING INTO THIS AGREEMENT.

                 SECTION 9.12.    Waiver of Immunities.       To the extent
that the Guarantor has or hereafter may acquire any immunity from jurisdiction
of any court or from any legal process (whether through service or notice,
attachment prior to judgment, attachment in aid of execution, execution or
otherwise) with respect to itself or its property, the Guarantor hereby
irrevocably waives such immunity in respect of its obligations under this
Agreement and its Guaranty hereunder, the Guarantor Security Agreement, and any
other Loan Document to which it is a party.

                 SECTION 9.13.    Reinstatement; Certain Payments.  If a claim
is ever made upon the Lender for repayment or recovery of any amount or amounts
received by the Lender in payment or on account of any of the Obligations under
this Agreement, the Lender shall give prompt notice of such claim to the
Borrower, and if the Lender repays all or part of said amount by reason of (i)
any judgment, decree or order of any court or administrative body having
jurisdiction over the Lender or any of its property, or (ii) any settlement or
compromise of any such claim effected by the Lender with any such claimant,
then and in such event the Borrower and each Guarantor (A) agree that any such
judgment, decree, order, settlement or compromise shall be binding upon the
Borrower and each Guarantor notwithstanding the cancellation of the Note or
other instrument evidencing the Obligations under this Agreement or the other
Loan Documents or the termination of this Agreement or the other Loan
Documents, and (B) shall be and remain liable to the Lender hereunder for the
amount so repaid or recovered to the same extent as if such amount had never
originally been received by the Lender.

                 SECTION 9.14.    Indemnification.  In addition to all of their
other Obligations under this Agreement, the Borrower and each Guarantor agree
to defend, protect, indemnify and hold harmless the Lender, and all of the
respective officers, directors, employees, attorneys, consultants and agents
(including, without limitation, those retained in connection with the
satisfaction or attempted satisfaction of any of the conditions set forth in
this Agreement) of the Lender (collectively called the "Indemnitees") from and
against any and all losses, damages, liabilities, obligations, penalties, fees,
costs and expenses (including, without limitation, attorneys' fees, costs and
expenses) incurred by such Indemnitees, whether prior to or from and after the
Effective Date, whether direct, indirect or consequential, as a result of or
arising from or relating to any suit, investigation, action or proceeding by
any Person, whether threatened or initiated, asserting a claim for any legal or
equitable remedy against any Person under any statute or regulation, including,
without limitation, any Federal or state securities or labor laws, or under any
Federal, state or local environmental, health or safety laws, regulations or,
common law principles, arising from or in connection with the past, present or
future operations of the Borrower or its predecessors in interest, arising from
or in connection with any of the following:  (i) the negotiation, preparation,
execution or performance of this Agreement or of any document executed in
connection with the transactions contemplated by this Agreement, (ii) the
Lender's furnishing of funds to the Borrower under this Agreement, including,
without limitation, the management of the Loan, or (iii) any matter relating to
the financing transactions contemplated by this Agreement or by any document
executed in connection with the transactions contemplated by





                                      -44-
<PAGE>   50
this Agreement (collectively, the "Indemnified Matters"); provided, however,
that the Borrower and each Guarantor shall have no obligation to any Indemnitee
hereunder for any Indemnified Matter caused by or resulting from the gross
negligence or willful misconduct of such Indemnitee, as determined by a final
judgment of a court of competent jurisdiction.  Such indemnification for all of
the foregoing losses, damages, fees, costs and expenses of the Lender shall be
part of the Obligations, secured by the Collateral.  To the extent that the
undertaking to indemnify, pay and hold harmless set forth in this Section 9.14
may be unenforceable because it is violative of any law or public policy, the
Borrower shall contribute the maximum portion which it is permitted to pay and
satisfy under applicable law, to the payment and satisfaction of all
Indemnified Matters incurred by the Indemnitees.  The provisions of this

                                    GUARANTY

                 SECTION 10.01.   Guaranty.  UGNL, and each other Guarantor
that may become party hereto, hereby (i) irrevocably, absolutely and
unconditionally guarantees the prompt payment, as and when due and payable
(whether by scheduled maturity, required prepayment, acceleration, demand or
otherwise), of (A) all the Obligations, including, without limitation, all
amounts now or hereafter owing in respect of the Loan Documents, whether for
principal, interest, fees, expenses or otherwise, and (B) all indebtedness,
obligations and other liabilities, direct or indirect, absolute or contingent,
now existing or hereafter arising of the Borrower to the Lender and (ii)
agrees, to pay any and all expenses (including reasonable counsel fees and
expenses) incurred by the Lender in enforcing its rights under this Article X.

                 SECTION 10.02.   Obligations Unconditional.

                                  (i)      UGNL and each other Guarantor that
may become party hereto, hereby guarantees that the Obligations will be paid
strictly in accordance with the terms of the Loan Documents, regardless of any
law, regulation or order now or hereafter in effect in any jurisdiction
affecting any of such terms or the rights of the Lender with respect thereto.
UGNL and each other Guarantor agrees that its guarantee constitutes a guaranty
of payment when due and not of collection, and waives any right to require that
any resort be had by the Lender to any security held for payment of the
Obligations or to any balance of any deposit account or credit on the books of
the Lender in favor of the Borrower or for any other reason.  The liability of
UGNL and each other Guarantor hereunder shall be absolute and unconditional
irrespective of:  (i) any lack of validity or enforceability of any Loan
Document or any agreement or instrument relating thereto; (ii) any extension or
change in the time, manner or place of payment of, or in any other term in
respect of, all or any of the Obligations (including, without limitation, any
extension for longer than the original period), or any other amendment or
waiver of or consent to any departure from any provision of any Loan Document;
(iii) any exchange or release of, or non-perfection of any lien on or security
interest in, any Collateral, or any release or amendment or waiver of or
consent to any departure from any other guaranty, for all or any of the
Obligations; or (iv) any





                                      -45-
<PAGE>   51
other circumstance which might otherwise constitute a defense available to, or
a discharge of, the Borrower or any other guarantor in respect of the
Obligations or UGNL and each other Guarantor in respect hereof.

                                  (ii)     This Guaranty (i) is a continuing
guaranty and shall remain in full force and effect until such date on which all
of the Obligations and all other expenses to be paid by UGNL or any other
Guarantor pursuant hereto shall have been satisfied in full after the
Commitment shall have been terminated, (ii) shall continue to be effective or
shall be reinstated, as the case may be, if at any time any payment of any of
the Obligations is rescinded or must otherwise be returned by the Lender upon
the insolvency, bankruptcy or reorganization of the Borrower or otherwise, all
as though such payment had not been made, and (iii) shall be binding upon UGNL,
any other Guarantor or their respective heirs, executors, successors and
assigns.

                 SECTION 10.03.   Waivers.  UGNL and each other Guarantor
hereby waives, to the extent permitted by applicable law, (i) promptness and
diligence, (ii) notice of acceptance and notice of the incurrence of any
Obligation, (iii) notice of any action taken by the Lender or the Borrower or
any other Loan Party under any Loan Document or any other agreement or
instrument relating thereto, (iv) all other notices, demands and protests, and
all other formalities of every kind in connection with the enforcement of the
Obligations or of the obligations of UGNL and each other Guarantor hereunder,
the omission of or delay in which, but for the provisions of this Section
10.03, might constitute grounds for relieving UGNL or any other Guarantor of
its obligations hereunder, and (v) any requirement that the Lender protect,
secure, perfect or insure any security interest or lien or any property subject
thereto or exhaust any right or take any action against any Person or any
Collateral.  All such waivers by UGNL shall be effective only to the extent
permitted by applicable law.

                 SECTION 10.04.   Subrogation.  Neither UGNL nor any other
Guarantor will exercise any rights which it may acquire by way of subrogation
hereunder, by any payment made by it hereunder or otherwise, until such date on
which all of the Obligations and all other expenses to be paid by UGNL or such
other Guarantor pursuant hereto shall have been satisfied in full.  If any
amount shall be paid to UGNL or such other Guarantor on account of such
subrogation rights at any time when all of the Obligations and all such other
expenses shall not have been paid in full, such amount shall be held in trust
for the benefit of the Lender, shall be segregated from the other funds of UGNL
or such other Guarantor and shall forthwith be paid over to the Lender to be
applied in whole or in part by the Lender against the Obligations, whether
matured or unmatured, and all such other expenses in accordance with the terms
of the Loan Agreement.  If (i) UGNL or such other Guarantor shall make payment
to the Lender of all or any portion of the Obligations and (ii) all of the
Obligations and all such other expenses shall be paid in full, the Lender will,
at UGNL's or such other Guarantor's request, execute and deliver to UGNL or
such other Guarantor (without recourse, representation or warranty) appropriate
documents necessary to evidence the transfer by subrogation to UGNL or such
other Guarantor of an interest in the Obligations resulting from such payment
by UGNL or such other Guarantor, such subrogation to be fully subject and
subordinate, however, to the collection by the Lender of all other amounts due
to the Lender by the Borrower and each other Loan Party under the Loan
Agreement and the other Loan Documents





                                      -46-
<PAGE>   52
                 SECTION 10.05.   No Waiver; Remedies.  No failure on the part
of the Lender to exercise, and no delay in exercising, any right hereunder
shall operate as a waiver thereof; nor shall any single or partial exercise of
any right hereunder preclude any other or further exercise thereof or the
exercise of any other right.  The remedies herein provided are cumulative and
not exclusive of any remedy provided by law.

                 SECTION 10.06.   Taxes .

                 (a)      Each payment by UGNL or any other Guarantor under
this Loan Agreement shall be made without withholding for or on account of any
present or future taxes, levies, imposts, deductions, charges or withholdings,
and all liabilities with respect thereto, excluding, in the case of the Lender,
taxes imposed on its income, and franchise taxes imposed on it by the
jurisdiction (or any political subdivision thereof) under the laws of which the
Lender is organized (all such nonexcluded taxes, levies, imposts, deductions,
charges, withholdings and liabilities being hereinafter referred to as
"Taxes"); provided, however, that if such Taxes are required by law to be
withheld from any such payment, UGNL, or such other Guarantor, as applicable,
shall make such withholding for the account of the Lender, make timely payment
thereof to the appropriate governmental authority, and forthwith pay for the
account of the Lender such additional amount as may be necessary so that after
making all required deductions (including deductions applicable to additional
sums payable under this Section 10.06) the Lender receives an amount equal to
the sum it would have received had no such deductions been made. All such Taxes
shall be paid by UGNL, or such other Guarantor, as applicable, prior to the
date on which penalties attach thereto or interest accrues thereon; provided,
however, that, if any such penalties or interest become due, UGNL, or such
other Guarantor, as applicable, shall make prompt payment thereof to the
appropriate Governmental Authority.

                 (b)      UGNL and each other Guarantor will indemnify the
Lender for the full amount of Taxes (including any Taxes on amounts payable
under this Section 10.06.) paid by the Lender and any liability (including
penalties, interest and expenses) arising therefrom or with respect thereto,
whether or not such Taxes were correctly or legally asserted. This
indemnification shall be made within 30 days from the date the Lender makes
written demand therefor.

                 (c)      Within 30 days after the date of any payment of
Taxes, UGNL or such other Guarantor, as applicable, will furnish to the Lender
the original or a certified copy of a receipt evidencing payment thereof. If no
Taxes are payable in respect of any payment hereunder or under the Note, UGNL
or such other Guarantor, as applicable, will furnish to the Lender a
certificate from each appropriate taxing authority, or an opinion of counsel
acceptable to the Lender, in either case stating that such payment is exempt
from or not subject to Taxes.

                 (d)      In addition, UGNL or such other Guarantor will pay
any stamp or other taxes of any jurisdiction with respect to the execution,
delivery, registration, performance and enforcement of this Guaranty, Taxes
specified in subsection (a) above and taxes of all jurisdictions with respect
to any amounts paid under this subsection (d).  If any Taxes specified in
subsection (a) above or any taxes referred to in this subsection (d) are paid
by the Lender, UGNL or such





                                      -47-
<PAGE>   53
other Guarantor will, upon demand of the Lender, and whether or not such Taxes
or taxes shall be correctly or legally asserted, indemnify the Lender for such
payments, together with any interest, penalties and expenses in connection
therewith, plus interest thereon at the highest rate specified in the Note
(calculated as if such payments constituted overdue amounts of principal as of
the date of the making of such payments).

                 SECTION 10.07.   Judgment.  If, for the purposes of obtaining
judgment in any court, it is necessary to convert a sum due from the Guarantor
hereunder in United States Dollars into another currency (the "Other
Currency"), the rate of exchange used shall be that at which the Lender could,
in accordance with normal banking procedures, purchase United States Dollars
with the Other Currency on the Business Day preceding that on which final
judgment is given.  The obligation of the Guarantor in respect of any such sum
due from it to the Lender hereunder shall, notwithstanding any judgment in such
Other Currency, be discharged only to the extent that, on the Business Day
immediately following the date on which the Lender receives any sum adjudged to
be so due in the Other Currency, the Lender may, in accordance with normal
banking procedures, purchase United States Dollars with the Other Currency.  If
the United States Dollars so purchased are less than the sum originally due to
the Lender in United States Dollars, the Guarantor agrees, as a separate
obligation and notwithstanding any such judgment, to indemnify the Lender
against such loss, and if the United States Dollars so purchased exceed the sum
originally due to the Lender in United States Dollars, the Lender agrees to
remit to the Guarantor such excess.

                 SECTION 10.08.   Payment.  The Guarantor will make each
payment hereunder in lawful money of the United States of America and in
immediately available funds to the Loan Account.

                 SECTION 10.09.   Stay of Acceleration.  If acceleration of the
time for payment of any amount payable by the Borrower in respect of the
Obligations is stayed upon the insolvency, bankruptcy or reorganization of the
Borrower, all such amounts otherwise subject to acceleration under the terms of
this Agreement shall nonetheless be payable by UGNL and any other Guarantor
hereunder forthwith on demand by the Lender.

             FOR VALUE RECEIVED, GRANT GEOPHYSICAL, INC., a Delaware
