$10,500,000.00                                             Boston, Massachusetts
                                                                    July 1, 2001

                  FOR VALUE RECEIVED, GRANT GEOPHYSICAL, INC., a Delaware
corporation ("Borrower"), promises to pay to the order of FOOTHILL CAPITAL
CORPORATION, a California corporation ("Foothill"), at its offices at 11111
Santa Monica Boulevard, Suite 1500, California 90025-3333, or at such other
place or places as Foothill may from time to time designate in writing, the
principal sum of Ten Million Five Hundred Thousand and No/100 Dollars
($10,500,000.00), plus interest in the manner and upon the terms and conditions
set forth below. This Fourth Amended and Restated Secured Promissory Note (this
"Note") is made pursuant to that certain Loan and Security Agreement (as
amended, the "Loan Agreement"), dated as of May 11, 1999, among Borrower, the
lending entities from time to time party thereto (together with their respective
successors and assigns, the "Lenders"), and Foothill, as agent for the Lenders
(the "Agent"), the provisions of which are incorporated herein by this
reference, and evidences the FCC Term Loan, as defined and described in the Loan
Agreement. Capitalized terms herein, unless otherwise noted, shall have the
meaning set forth in the Loan Agreement.

1.0 SCHEDULE OF PAYMENTS; RATE AND PAYMENT OF INTEREST; PREPAYMENT.

                  1.1 Except to the extent this Note may become due and payable
earlier in accordance with the Loan Agreement, this Note shall be due and
payable in as follows:

                  (a) forty-one (41) equal successive monthly installments of
         principal of Two Hundred Fifty Thousand and No/100 ($250,000.00), each
         on the first day of each month, beginning August 1, 2001, and
         continuing through and including December 1, 2004;

                  (b) accrued interest on the principal balance from time to
         time remaining unpaid, payable monthly on the first day of each and
         every month, beginning August 1, 2001; and

                  (c) a final principal installment equal to the unpaid
         principal balance of this Note on January 1, 2005, together with
         accrued interest on the principal balance remaining unpaid.

                  1.2 Prepayment may be made under this Note in whole or in
part, subject to the provisions of Section 3.6 set forth in the Loan Agreement.
Notwithstanding anything herein to the contrary, in the event that the Loan
Agreement is terminated by Borrower, by Foothill or by any other person at any
time, then the entire unpaid principal balance of this Note, together with all
accrued and unpaid interest hereon, shall become immediately due and payable in
full on the effective date of such termination, without presentment, notice or
demand of any kind.

                  1.3 Interest shall be computed on the basis of a 360-day year
for the actual number of days elapsed, and shall be at the rate of one and
one-half (1- 1/2) percentage points above the Reference Rate (as hereinafter
defined), computed on the basis of a 360-day year; provided, however, upon the
occurrence and during the continuance of an Event of Default (as hereinafter
defined), interest shall accrue on the outstanding principal balance of this
Note at a default rate (the "Default Rate") of five and one-half (5- 1/2)
percentage points above the Reference Rate, and shall be payable on demand.
"Reference Rate" means, for any day, the rate of interest per annum (over a year
of 360 days) announced by Wells Fargo Bank, National Association, or any
successor thereto (the "Bank"), from time to time, as its "base rate" (or any
successor thereto) in effect on such day. The Reference Rate is not necessarily
the lowest rate charged by the Bank. The applicable rate of interest assessed
hereunder will be increased or

Secured Promissory Note - Page 1
<PAGE>

decreased from time to time hereafter in an amount equal to any increase or
decrease hereafter made by the Bank in the Reference Rate. A change in the
Reference Rate shall be effective automatically and immediately on the
occurrence of such change.

2.0 EVENTS OF DEFAULTS; REMEDIES.

                  2.1 The occurrence of an Event of Default under the Loan
Agreement shall constitute a default by Borrower under this Note (hereinafter an
"Event of Default").

                  2.2 Upon the occurrence of any Event of Default hereunder, the
Lenders and the Agent shall have all rights and remedies as may be provided
under the Loan Agreement or applicable law.

3.0 GENERAL PROVISIONS.

                  3.1 Borrower warrants and represents to the Agent and the
Lenders that Borrower has used and will continue to use the loans and advances
represented by this Note solely for proper business purposes, and consistent
with all applicable laws and statutes.

                  3.2 This Note is secured by the Collateral described in the
Loan Agreement.

                  3.3 Borrower waives presentment, demand and protest, notice of
protest, notice of presentment, notice of intention to accelerate, notice of
acceleration, and all other notices and demands in connection with the
enforcement of the Lenders', Foothill's or the Agent's rights hereunder or under
the Loan Agreement, except as specifically provided and called for by this Note
or the Loan Agreement, and hereby consents to, and waives notice of, the
release, addition, or substitution, with or without consideration, of any
collateral or of any person liable for payment of this Note or any other
Obligation. Any failure of the Lenders or the Agent to exercise any right
available hereunder, under the Loan Agreement or otherwise shall not be
construed as a waiver of the right to exercise the same or as a waiver of any
other right at any other time.

                  3.4 If this Note is not paid when due or upon the occurrence
of an Event of Default, Borrower further promises to pay all costs of
collection, foreclosure fees, attorneys' fees and expert witness fees incurred
by the Lenders or the Agent, whether or not suit is filed hereon, and the fees,
costs and expenses as provided in the Loan Agreement.

                  3.5 It is the intent of the parties to comply with applicable
usury laws (the "Applicable Usury Law"). Accordingly, it is agreed that
notwithstanding any provisions to the contrary in this Note, or in any of the
documents securing payment hereof or otherwise relating hereto, in no event
shall this Note or such documents require the payment or permit the collection
of interest in excess of the Maximum Interest Rate, then in any such event (1)
the provisions of the paragraph shall govern and control, (2) neither Borrower
nor any other person or entity now or hereafter liable for the payment hereof
shall be obligated to pay the amount of such interest to the extent that it is
in excess of the Maximum Interest Rate, (3) any such excess which may have been
collected shall be either applied as a credit against the then unpaid principal
amount hereof or refunded to Borrower, at Foothill's option, and (4) the
effective rate of interest shall be automatically reduced to the Maximum
Interest Rate. It is further agreed, without limiting the generality of the
foregoing, that to the extent permitted by the Applicable Usury Law, (x) all
calculations of interest which are made for the purpose of determining whether
such rate would exceed the Maximum Interest Rate shall be made by amortizing,
prorating, allocating and spreading during the period of the full stated term of
the loan evidenced hereby, all interest at any time contracted for, charged or
received from Borrower or otherwise in connection with such loan; and (y) in the
event that the effective rate of interest on the loan should at any time exceed
the Maximum Interest

Secured Promissory Note - Page 2
<PAGE>

Rate, such excess interest that would otherwise have been collected had there
been no ceiling imposed by the Applicable Usury Law shall be paid to Foothill
from time to time, if and when the effective interest rate on the loan otherwise
falls below the Maximum Interest Rate, until the entire amount of interest which
would otherwise have been collected had there been no ceiling imposed by the
Applicable Usury Law has been paid in full. Borrower further agrees that should
the Maximum Interest Rate be increased at any time hereafter because of a change
in the Applicable Usury Law, then to the extent not prohibited by the Applicable
Usury Law, such increases shall apply to all indebtedness evidenced hereby
regardless of when incurred; but, again to the extent not prohibited by the
Applicable Usury Law, should the Maximum Interest Rate be decreased because of a
change in the Applicable Usury Law, such decreases shall not apply to the
indebtedness evidenced hereby regardless of when incurred.

                  3.6 Subject to the applicable provisions of the Loan
Agreement, Foothill may at any time transfer this Note and Foothill's rights in
any or all collateral securing this Note, and Foothill thereafter shall be
relieved from all liability with respect to such collateral arising after the
date of such transfer.

                  3.7 This Note shall be binding upon Borrower and its legal
representatives, successors and assigns. Wherever possible, each provision of
this Note shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of the Note shall be prohibited by or
invalid under such law, such provision shall be severable, and be ineffective to
the extent of such prohibition or invalidity, without invalidating the remaining
provision of this Note.

                  THIS NOTE HAS BEEN DELIVERED FOR ACCEPTANCE BY FOOTHILL IN
BOSTON, MASSACHUSETTS AND SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE INTERNAL LAWS (AS OPPOSED TO THE CONFLICTS OF LAW PROVISIONS) OF THE
COMMONWEALTH OF MASSACHUSETTS, AS THE SAME MAY FROM TIME TO TIME BE IN EFFECT,
INCLUDING, WITHOUT LIMITATION, THE UNIFORM COMMERCIAL CODE AS ADOPTED IN
MASSACHUSETTS. BORROWER HEREBY (i) IRREVOCABLY SUBMITS TO THE JURISDICTION OF
ANY STATE OR FEDERAL COURT LOCATED IN SUFFOLK COUNTY, MASSACHUSETTS OVER ANY
ACTION OR PROCEEDING TO ENFORCE OR DEFEND ANY MATTER ARISING FROM OR RELATED TO
THIS NOTE; (ii) IRREVOCABLY WAIVES, TO THE FULLEST EXTENT BORROWER MAY
EFFECTIVELY DO SO, THE DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF
ANY SUCH ACTION OR PROCEEDING; (iii) AGREES NOT TO INSTITUTE ANY LEGAL ACTION OR
PROCEEDING AGAINST FOOTHILL OR ANY OF FOOTHILL'S DIRECTORS, OFFICERS, EMPLOYEES,
AGENTS OR PROPERTY, CONCERNING ANY MATTER ARISING OUT OF OR RELATING TO THIS
NOTE IN ANY COURT OTHER THAN ONE LOCATED IN SUFFOLK COUNTY, MASSACHUSETTS; AND
(iv) IRREVOCABLY WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION ARISING UNDER
OR IN CONNECTION WITH THIS NOTE. NOTHING IN THIS PARAGRAPH SHALL AFFECT OR
IMPAIR FOOTHILL'S RIGHT TO SERVE LEGAL PROCESS IN ANY MANNER PERMITTED BY LAW OR
FOOTHILL'S RIGHT TO BRING ANY ACTION OR PROCEEDING AGAINST BORROWER OR
BORROWER'S PROPERTY IN THE COURTS OF ANY OTHER JURISDICTION.

                  This Note amends, modifies, restates and replaces, but does
not extinguish the indebtedness evidenced by, that certain Third Amended and
Restated Secured Promissory Note, dated March 21, 2001, effective as of February
14, 2000, executed by Borrower and payable to the order of Foothill in the

                AGREEMENT FOR PURCHASE AND ASSIGNMENT OF FOREIGN
                              ACCOUNTS RECEIVABLE

This Agreement ("Agreement") is dated this 3rd day of August, 2001, and is
between Elliott Associates, L.P. , a Delaware Limited Partnership, as the
prospective purchaser and assignee of foreign accounts receivable (hereinafter
called "Elliott") and Grant Geophysical (Int'l), Inc., a Texas corporation, as
the prospective seller and assignor of accounts receivables (hereinafter called
"Grant").

         WHEREAS, Grant desires, from time to time during the term of this
         Agreement, to sell billed and unbilled foreign accounts receivable to
         Elliott; and

         WHEREAS, Elliott agrees to purchase from Grant up to a maximum amount
         of Four Million USD ($4,000,000), at any point in time, commencing
         August 3, 2001 and extending through February 28, 2002; and

         WHEREAS, the parties hereto desire to enter into this Agreement to
         govern the purchase and sale of foreign accounts receivable;

         NOW THEREFORE, in consideration of the premises, the mutual agreements
         herein contained and for other good and valuable consideration, the
         receipt and sufficiency of which are hereby acknowledged, the parties
         agree as follows:

1.       OFFER OF ACCOUNTS. At its election from time to time during this
         Agreement, Grant agrees to offer for sale to Elliott certain of its
         billed and unbilled foreign accounts receivables ("accounts") arising
         out of seismic data acquisition and processing services rendered by
         Grant's branch operations in Ecuador and Columbia, and to sell to
         Elliott on the terms set forth in this Agreement such offered accounts
         (hereinafter defined as billed and unbilled/ work in progress foreign
         accounts receivable) as Elliott may accept for purchase in the
         countries of Ecuador and Columbia or in any other country mutually
         agreed to by the parties. The parties agree that the maximum aggregate
         face amount of accounts that Elliott will purchase hereunder at any
         time will not exceed Four Million Dollars USD ($4,000,000). Elliott's
         consent to purchase accounts in excess of such aggregate amounts herein
         set forth may only be evidenced by Elliott's acceptance for purchase of
         such offered accounts.

2.       PURCHASE AND SALE OF ACCOUNTS. Each account purchased by Elliott
         hereunder shall be purchased with recourse by Elliott against Grant and
         Grant shall likewise be obligated to Elliott for any breach by Grant of
         any representation, warranty or agreement of Grant contained herein.
         Notwithstanding any provision in this agreement to the contrary, it is
         contemplated by and it is the intention of the parties hereto that
         certain accounts of Grant may be considered and purchased as one
         account (herein a "batch") and the terms "account" and "accounts" as
         used herein may also refer to and mean a "batch" or "batches," as the
         case may be.

         In connection with each offer of accounts to Elliott, Grant agrees to
         deliver to Elliott a written assignment of the subject billed and
         unbilled accounts, and if so requested by Elliott, copies of all
         invoices or underlying contracts relating to such accounts and evidence
         of performance of the related services, in consideration for an advance
         calculated on the basis of Article 4 herein. It is agreed that any
         realized gains or losses resulting from currency fluctuations between
         the account purchase and settlement date shall be for Grant's account.

         Grant hereby sells, transfers, assigns and otherwise conveys to Elliott
         with full recourse (as a sale by Grant and a purchase by Elliott and
         not as security for any indebtedness or other obligation of Grant to
         Elliott) all right, title and interest of Grant in and to all billed
         and unbilled foreign accounts accepted by Elliott for purchase
         hereunder, together with all related rights (but not obligations) of
         Grant with respect thereto, including all

Page 1 of 6
<PAGE>

         contract rights, guarantees, letters of credit, liens in favor of
         Grant, insurance and other agreements and arrangements of whatever
         character from time to time supporting or securing payment of such
         accounts.

         Grant agrees to execute and deliver such bills of sale, assignments,
         letters of credit, notices of assignment, financing statements
         (including continuation statements) under the applicable UCC and other
         documents, and make such entries and markings in its books and records,
         and to take all such other actions (including the negotiation,
         assignment or transfer of negotiable documents, letters of credit or
         other instruments) to the extent necessary and as Elliott may request
         to further evidence or protect the sales and assignments of accounts
         and related rights to Elliott hereunder.

3.       TERMS OF ACCOUNTS. Except as otherwise may be agreed to in writing by
         Elliott from time to time, the terms of sale offered by Grant to its
         account debtors with respect to all accounts offered to Elliott for
         purchase hereunder shall be NET 30 DAYS for billed foreign accounts and
         in the case of unbilled foreign accounts, the terms shall be NET 30
         DAYS after actual billing of such unbilled accounts. After a foreign
         account has been purchased by Elliott, Grant, in its capacity as agent
         for Elliott, shall advise Elliott of the terms of sale set forth in the
         invoice relating to such account, or any other aspect of the account.

4.       PURCHASE PRICE. The purchase price for each account purchased hereunder
         shall consist of and be paid at a discounted rate of .991667 per dollar
         based on the US Dollar equivalency of each invoice before VAT. In the
         event the account is not collected within 30 days, an additional
         discount shall accrue and become payable to Elliott at a monthly rate
         of .83333 .

5.       SECURITY. For the purpose of securing Elliott (a) in the payment of any
         and all sums of money that may become due and owing Elliott from Grant
         by reason of this Agreement, (b) in the performance by Grant of Grant's
         obligations hereunder, and under any other agreement, contract,
         document, note or other instrument in favor of Elliott or its
         assignees, Grant hereby grants to Elliott a security interest in (i)
         all of the specific Grant foreign accounts sold, pursuant to this
         Agreement, as well as all books and records pertaining to all of the
         foregoing; (ii) Grant agrees to execute and deliver such financing
         statements under the applicable UCC and other documents, and make such

         other actions, as Elliott may request to further evidence, perfect,
         preserve or protect the security interest granted to Elliott hereunder.
         Elliott at its sole discretion, shall have all rights and remedies in
         respect of the lien and security interest herein granted as are
         provided in this Agreement, the UCC and other applicable foreign law,
         including the right at any time, before or after any default by Grant
         of any of its obligations hereunder, to notify account debtors and
         obligors on instruments to make payment to Elliott (or its designee)
         and to take control of proceeds to which Elliott is entitled, and to
         apply proceeds to (in addition to other obligations of Grant to
         Elliott) the reasonable attorneys' fees and legal expenses incurred by
         Elliott in connection with the disposition of collateral or the other
         exercise of rights and remedies by Elliott.

6.       AGENT. Elliott authorizes Grant to act as its agent for the
         administration and collection of each account. Grant agrees that, if
         any payment is made to Grant on any account purchased by Elliott from
         Grant hereunder, Grant (i) will remit such payment to Elliott on a
         timetable as mutually agreeable, but in any event no later than
         February 28, 2002; and (ii) will deliver such payments due to Elliott
         based on the calculations as described in Article 4 herein.

7.       REPRESENTATIONS AND WARRANTIES OF GRANT. Grant hereby represents and
         warrants to Elliott with respect to each account offered by Grant to
         Elliott hereunder that (i) Grant is the sole owner of such account,
         which account is free and clear of any liens, claims, equities or
         encumbrances whatsoever, and upon each purchase by Elliott of such
         account, Elliott will own such account free and clear of any liens,
         claims, equities or encumbrances whatsoever and the consideration
         received by Grant from Elliott for such account is fair and adequate,
         (ii) Grant is the sole obligee under such account, and has full power
         and is duly authorized to sell, assign and transfer such account to
         Elliott hereunder, and the date of sale of such billed foreign account
         is not more than 30 days after the date of the original invoice, (iii)
         Grant has no knowledge of any fact which would lead it to expect that,
         at the date of sale of such account to Elliott, such account will not
         be paid in the full stated amount when due, and (iv) such account
         arises out of the bona fide rendition of services performed by Grant,

         or all underlying services have been rendered by Grant, in complete
         fulfillment of all of the terms and conditions of a fully executed,
         delivered and unexpired contract with the account debtor, and the
         account debtor has accepted the services to which the account relates.

         Each representation and warranty of Grant contained in this Agreement
         shall be deemed to be made at and as of the date hereof and as of the
         date of each sale of foreign accounts to Elliott hereunder.

         Grant agrees to indemnify and hold Elliott harmless against any breach
         by Grant of any representation, warranty or agreement of Grant
         contained in this Agreement, and against any claims or damages arising
         out of the manufacture, sale, possession or use of, or otherwise
         relating to, goods, or the performance of services, associated with or
         relating to accounts or related rights purchased (or with respect to
         which a security interest is granted) hereunder.

8.       FINANCIAL STATEMENTS. Grant represents and warrants that all financial
         and other information provided by Grant to Elliott in connection with
         this agreement or made to induce Elliott to enter into this Agreement
         is true, complete and correct in all material respects. Grant agrees to
         furnish and shall continue to provide additional financial and business
         information concerning Grant and its business as Elliott may reasonably
         request, including copies of its Form 10-K and Form 10-Q filings with
         the United States Securities and Exchange Commission.

9.       TAXES. All VAT taxes and governmental charges of any kind imposed with
         respect to the rendering of services relating to foreign accounts
         purchased by Elliott hereunder shall be for the account of, and paid
         by, Grant.

10.      TERMINATION. This Agreement may be terminated by either party hereto by
         delivery of written notice of termination of this Agreement to the
         other party specifying the date of termination, which date shall be at
         least 30 days after the date such notice is given. Elliott may, at its
         election, terminate this Agreement immediately and without the
         requirement of notice to Grant if (i) Grant shall fail to perform any
         of its obligations hereunder or shall breach any of its representations
         and warranties hereunder, (ii) Grant or any of its Affiliates shall
         become insolvent or suspend all or a substantial part of its or their
         business, (iii) a petition under the Bankruptcy Code or any other

         affiliate or any receivership proceedings with respect thereto shall
         commence, (iv) any guarantee of any of Grant's obligations hereunder
         shall be terminated or become impaired, or (v) Elliott otherwise deems
         that it is insecure hereunder.

         Termination of this Agreement shall not affect the rights and
         obligations of the parties hereunder with respect to transactions
         occurring on or prior to the date of such termination, and this
         Agreement shall continue to govern the rights and obligations of the
         parties hereto with respect to accounts purchased by Elliott from Grant
         on or prior to the date of such termination. All security interests
         granted or contemplated by this Agreement shall survive the termination
         of this Agreement until all amounts payable to Elliott with respect to
         transactions occurring on or prior to the date of termination have been
         paid to Elliott, and Grant has performed all its obligations to Elliott
         with respect to such transactions, and all obligations under this
         Agreement including but not limited to payment of the Fees.

11.      ATTORNEY'S FEES, LITIGATION EXPENSE. Grant agrees to reimburse Elliott
         upon demand for Elliott's attorneys' fees, court costs and other fees
         and expenses incurred in collecting any sums due or to become due to
         Elliott hereunder, enforcing any of Elliott's rights under this
         Agreement and all actions taken by Elliott that it deems necessary or
         desirable under the Bankruptcy Code or should any provisions of the
         Bankruptcy Code be applicable to any rights or obligations of any party
         to this Agreement, as well as all appearances, motions and actions to
         which ELLIOTT may be or become a party in any bankruptcy case.

12.      GOVERNING LAW; VENUE; SUBMISSION TO JURISDICTION. This Agreement shall
         be governed by and interpreted in accordance with the internal laws (as
