L.P. ("Borrower"), a Delaware limited partnership, TIDEL TECHNOLOGIES, INC., a
Delaware corporation ("Ultimate Parent"), and CHASE BANK OF TEXAS, N.A., a
national banking association (the "Lender").

                              W I T N E S S E T H:

         THAT, in consideration of the mutual covenants, agreements and
undertakings herein contained, the parties hereto agree as follows:

1. Definitions.

         1.1 Certain Defined Terms. Unless a particular word or phrase is
otherwise defined or the context otherwise requires, capitalized words and
phrases used in the Loan Documents have the meanings provided below.

         Adjusted LIBOR Rate shall mean, with respect to any LIBOR Borrowing for
any Interest Period, an interest rate per annum (rounded upwards, if necessary,
to the next 1/16 of 1%) equal to the sum of (a) the product of (i) the sum of

and (b) the Applicable Margin.

         Affiliate of any Person shall mean any other Person which controls or
is controlled by or under common control with such Person and, without limiting
the generality of the foregoing, includes (a) any Person which beneficially owns
or holds five percent (5%) or more of any class of voting securities of such
Person or five percent (5%) of the equity interest in such Person, (b) any
Person of which such Person beneficially owns or holds five percent (5%) or more
of any class of voting securities or in which such Person beneficially owns or
holds five percent (5%) or more of the equity interest in such Person, and (c)
any director, officer or employee of such Person. For purposes of this
definition, "control" (including "controlled by" and "under common control
with") means the possession, directly or indirectly, of the power to direct or
cause the direction of the management and policies of such Person, whether
through the ownership of securities, partnership or other ownership interests,
by contract or otherwise.

         Alternate Base Rate shall mean, for any day, a rate per annum (rounded
upwards to the nearest 1/16 of 1%) equal to the sum of the following:

         (a) the greater of (i) the Prime Rate (computed on the basis of the
actual number of days elapsed over a year of 360 days, as the case may be) in
effect on such day, (ii) the Federal Funds Effective Rate (computed on the basis
of the actual number of days elapsed over a 360-day year) in effect for such day

Secondary CD Rate shall be effective on the effective date of such change in the
Prime Rate, Federal Funds Effective Rate or the Three-Month Secondary CD Rate,
respectively. If for any reason the Lender shall have determined (which
determination shall be conclusive and binding, absent manifest error) that it is
unable to ascertain the Federal Funds Effective Rate or Base CD Rate, or both,
for any reason, including the inability or failure of the Lender to obtain
sufficient quotations in accordance with the terms hereof, the Alternate Base
Rate shall be determined without regard to clauses (a)(ii) or (a)(iii), or both,
as appropriate, until the circumstances giving rise to such inability no longer
exist.

of the principal balance of the Revolving Loans bearing interest at the

form the corresponding figures from the previous fiscal year, all prepared in

certified public accountants with a "Big 6" accounting firm or other accounting
firm of similar national standing and reputation, which report shall not contain
any qualification except with respect to new accounting principles mandated by
the Financial Accounting Standards Board and shall state that such financial
statements, in the opinion of such accountants, present fairly, in all material
respects, the financial position of such Person as of the date thereof and the
results of its operations and cash flows for the period covered thereby in
conformity with GAAP. The Annual Audited Financial Statements for the Borrower
and its Subsidiaries shall be prepared on a Consolidated and consolidating basis
in accordance with GAAP. All such Annual Audited Financial Statements shall be
accompanied by a certificate of such accountants that in making the appropriate
audit and/or investigation in connection with such report and opinion, such
accountants did not become aware of any Default or Event of Default, or if in
the opinion of such accountant any such Default or Event of Default exists, a
description of the nature and status thereof.

         Annual Consolidating Financial Statements shall mean the annual audited
consolidating financial statements of a Person, including all notes thereto,
which statements shall include a balance sheet as of the end of such fiscal year
and an income statement, a retained earnings statement and a statement of cash

account debtor exceeding such respective percentage limit shall be included
within Eligible Receivables (subject to compliance with all other applicable
standards of eligibility) only if the Receivables exceeding such respective
percentage limit are backed or secured by credit insurance reasonably
satisfactory to the Lender in all respects and such credit insurance has been

of such objection, return, rejection or repossession, subject to compliance with
all other standards of eligibility); (j) the applicable account debtor is not

CREDIT AGREEMENT - Page 7
<PAGE>   16

notice precludes bringing suit against the applicable account debtor, the
Borrower must have filed such requisite activities report or other similar
report and otherwise be in compliance with such Legal Requirement to the extent
necessary to allow the Borrower to bring suit against the applicable account
debtor in the applicable state or states; and (r) the Lender is satisfied in its
reasonable discretion with the credit standing of the applicable account debtor

and after the Closing Date until, but not including, the Revolving Loan Maturity
Date, in an aggregate principal amount at any one time outstanding (including
the Lender's Letter of Credit Exposure Amount at such time) up to, but not
exceeding the Lender's Revolving Commitment. Notwithstanding the foregoing, the
aggregate principal amount of the Revolving Loans outstanding at any time shall
not exceed (a) the lesser of (i) the Revolving Commitment and (ii) the
applicable Borrowing Base at such time less (b) the Letter of Credit Exposure
Amount at such time. Subject to the conditions herein, any such Revolving Loan
repaid prior to the Revolving Loan Maturity Date may be re-borrowed as an
additional Revolving Loan by the Borrower pursuant to the terms of this
Agreement.

         2.2 Revolving Loans.

                  (a) Subject to Sections 5.1 and 5.2 hereof, (i) all Revolving
Loans shall be advanced in accordance with the Lender's Revolving Commitment;
and (ii) the initial Revolving Loans shall be made on the Closing Date by the
Lender against delivery of the Revolving Note.

                  (b) When requesting a Revolving Loan hereunder, the Borrower
shall give the Lender notice of a request for a Revolving Loan in accordance
with Section 5.1(a) hereof.

                  (c) Except as otherwise provided or specified in Section
2.2(f) below, the Lender shall make its Revolving Loans available on the

Office.

                  (d) Each Revolving Loan made by the Lender on any date shall
be in an amount greater than $10,000; provided, however, that the LIBOR
Borrowings made on any date shall be in a minimum aggregate principal amount of
$500,000, with any increases over such minimal amount being in integral
aggregate multiples of $100,000.



CREDIT AGREEMENT - Page 22
<PAGE>   31

                  (e) When and if the daily collection and application
procedures for Receivables are implemented and are continuing in accordance with
the provisions of Section 7.15(b) hereof, the Lender shall render to the
Borrower each month a statement of the Borrower's account of all transactions
which shall be deemed to be correct and accepted by and be binding upon the
Borrower unless the Lender receives a written statement of the Borrower's
exceptions to such account statement within thirty (30) days after such
statement was rendered to the Borrower.

         2.3 Commitment and Other Fees.

                  (a) In consideration of the Lender's Revolving Commitment, the
Borrower agrees to pay to the Lender a commitment fee ("Commitment Fee")
(computed on the basis of the actual number of days elapsed in a year composed
of 360 days, subject to the terms of Section 10.6 hereof) in an amount equal to
the product of (A) one quarter of one percent (0.25%) times (B) the Lender's
Unused Revolving Commitment. The Commitment Fee shall be due and payable in
arrears (i) on the first Business Day of each December, March, June and
September prior to the Revolving Loan Maturity Date, commencing June 1, 1999,
and (ii) on the Revolving Loan Maturity Date, with each Commitment Fee to
commence to accrue as of the date hereof and to be effective as to any reduction
in the Revolving Commitment as of the date of any such decrease, and each
Commitment Fee shall cease to accrue (except with respect to interest at the
Past Due Rate on any unpaid portion thereof) on the Revolving Loan Maturity
Date. All past due Commitment Fees shall bear interest at the Past Due Rate and
shall be payable upon demand by the Lender.

                  (b) When and if the daily collection and application
procedures for Receivables are implemented and are continuing in accordance with
the provisions of Section 7.15(b) hereof, the Borrower hereby agrees to pay to
the Lender an administration fee in the amount of $10,000 per annum, payable in
advance in semi-annual installments of $5,000, commencing on any date such daily
collection procedures are implemented, and thereafter semi-annually on the same
Business Day of each subsequent six-month period in which such daily collection
procedures are continuing; provided, however, prior to the implementation of
such collection procedures, Borrower hereby agrees to pay the Lender an
administration fee in the amount of $5,000 per annum, payable in advance with
the first payment being due and payable on [the Closing Date (such amount having
been paid)] and annually thereafter, on each anniversary of the Closing Date.

         2.4 Termination and Reductions of Revolving Commitment.

                  (a) Upon at least five (5) Business Days' prior irrevocable
written notice to the Lender, the Borrower may at any time in whole permanently
terminate, or from time to time in part permanently reduce, the Commitment;
provided, however, that the Revolving Commitment shall not be reduced at any
time to an amount not less than the aggregate of the Lender's Current Sum
outstanding at such time. Each partial reduction of the Revolving Commitment
shall be in a minimum of $500,000 or an integral multiple of $100,000 in excess
thereof.



CREDIT AGREEMENT - Page 23
<PAGE>   32

                  (b) Simultaneously with any termination or reduction, in whole
or in part, of Revolving Commitment pursuant to Section 2.4(a) above, the
Borrower hereby agrees to pay to the Lender, (i) the Commitment Fee due and
owing through and including date of such termination or reduction on the amount
of the Revolving Commitment of the Lender so terminated or reduced and (ii)
unless such termination or reduction is accomplished with the proceeds of an
Initial Public Offering, a prepayment fee equal to one percent (1.00%) of the
Revolving Commitment of the Lender so terminated or reduced if such termination
or reduction occurs on or before the first anniversary of the Closing Date.
After the first anniversary date of the Closing Date, the Revolving Commitment
may be terminated or reduced, in whole or in part, without any prepayment fee,
penalty or other similar charge.

                  (c) To effect the payment of any and all Commitment Fees and
all other Obligations outstanding and owing hereunder or under any other Loan
Documents, subject to the provisions of Sections 2.1 and 5.1 hereof, the Lender
may, but shall not be obligated to, make a Revolving Loan if (i) such Revolving
Loan is to be made prior to the Revolving Loan Maturity Date, (ii) the
Availability would be equal to or greater than zero after giving effect to such
Revolving Loan, and (iii) no Default or Event of Default shall have occurred
which is then continuing. The inability of the Lender to cause the payment of
any such Commitment Fees or other Obligations in accordance with the preceding
sentence shall not in any way whatsoever affect the Borrower's and Guarantors'
obligation to otherwise pay such amounts in accordance with the applicable terms
hereof or of any other Loan Documents.

         2.5 Mandatory and Voluntary Prepayments.

                  (a) If the Current Sum applicable to the Lender at any time
exceeds the Lender's Revolving Commitment, the Lender shall notify the Borrower
of the deficiency (such notice being permitted to be given orally and need not
be in writing) and the Borrower shall immediately make a prepayment on the
Lender's Revolving Note or otherwise reimburse Lender for Letter of Credit
Advances or cause one or more Letters of Credit to be canceled and surrendered
in an amount sufficient to reduce the Lender's Current Sum to an amount no
greater than the Lender's Revolving Commitment. Any prepayments required by this
subparagraph (a) shall be applied to outstanding Alternate Base Rate Borrowings
up to the full amount thereof before such prepayments are applied to outstanding
LIBOR Borrowings (together with any Consequential Loss resulting from such
prepayment).

                  (b) The Borrower shall make prepayments of the Revolving Loans
from time to time so that the Availability equals or exceeds zero at all times.
Specifically, if the Availability at any time is less than zero, the Lender
shall notify the Borrower of the deficiency (such notice being permitted to be
given orally and need not be in writing) and the Borrower shall immediately make
a prepayment on the Revolving Note or otherwise reimburse the Lender for Letter
of Credit Advances or cause one or more Letters of Credit to be canceled and
surrendered in an amount sufficient to cause the Availability to be at least
equal to zero. Any prepayments required by this subparagraph (b) shall be
applied to outstanding Alternate Base Rate Borrowings up to the full amount
thereof before such prepayments are applied to outstanding LIBOR Borrowings
(together with any Consequential Loss resulting from such prepayment).



CREDIT AGREEMENT - Page 24
<PAGE>   33

         (c) In addition to the mandatory prepayments required by Sections
2.5(a) and above, the Borrower shall have the right, at its option and subject
to the requirements of Section 2.4, to prepay any of the Revolving Loans in
whole at any time or in part from time to time, without premium or penalty,
except as otherwise provided in Section 2.4, this Section 2.5 or subsections
(a), (b) or (c) of Section 2.9 hereof. Each prepayment under this subsection
shall applied to the prepayment of the aggregate unpaid principal amount of the
Revolving Note. Prepayments under this subparagraph (c) shall be subject to the
following additional conditions:

                           (1) In giving notice of prepayment as hereinafter
         provided, the Borrower shall specify, for the purpose of paragraphs (2)
         and (3) immediately following, the manner of application of such
         prepayment as between Alternate Base Rate Borrowings and LIBOR
         Borrowings; provided, that in no event shall any LIBOR Borrowing be
         partially prepaid.

                           (2) Prepayments applied to any LIBOR Rate Borrowing
         may be made on any Business Day, provided, that (i) the Borrower shall
         have given the Lender at least five (5) Business Days' prior
         irrevocable written or telecopied notice of such prepayment, specifying
         the principal amount of the LIBOR Borrowing to be prepaid, the
         particular LIBOR Borrowing to which such prepayment is to be applied
         and the prepayment date; and (ii) if such prepayment is made on any day
         other than the last day of the Interest Period corresponding to the
         LIBOR Borrowing to be prepaid, the Borrower shall pay directly to the
         Lender, on the last day of such Interest Period, the Consequential Loss
         as a result of such prepayment.

                           (3) Prepayments applied to any Alternate Base Rate
         Borrowing may be made on any Business Day, provided that the Borrower
         shall have given the Lender prior irrevocable written notice or notice
         by telephone (which is to be promptly confirmed in writing) of such
         prepayment on the Business Day of such prepayment, specifying the
         principal amount of the Alternate Base Rate Borrowing to be prepaid.

                  (d) Notice of any prepayment having been given, the principal
amount specified in such notice, together with (in the case of any prepayment of
a LIBOR Borrowing) interest thereon to the date of prepayment, shall be due and
payable on such prepayment date.

         2.6 Revolving Note; Payments.

                  (a) All Revolving Loans made by Lender to the Borrower shall
be evidenced by a single Revolving Note dated as of the Closing Date, delivered
and payable to the Lender in a principal amount equal to the Lender's Revolving
Commitment as of the Closing Date.

                  (b) The outstanding principal balance of each and every
Revolving Loan, as evidenced by the Revolving Note, shall mature and be fully
due and payable on the Revolving Loan Maturity Date.



CREDIT AGREEMENT - Page 25
<PAGE>   34

                  (c) Subject to Section 10.6 hereof, the Borrower hereby agrees
to pay accrued interest on the unpaid principal balance of the Revolving Loans
on the Interest Payment Dates, commencing the first of such dates to occur after
the date hereof. After the Revolving Loan Maturity Date, accrued and unpaid
interest on the Revolving Loans shall be payable on demand.

                  (d) To effect payment of accrued interest owing on the
Revolving Loans as of the Interest Payment Dates, subject to the provisions of
Sections 2.1 and 5.1 hereof, the Lender may, but shall not be obligated to, make
a Revolving Loan to pay in full the amount of accrued interest owing and payable
on the Revolving Loans as of the respective Interest Payment Date if (i) such
Revolving Loan is to be made prior to the Revolving Loan Maturity Date, (ii) the
Availability would be equal to or greater than zero after giving effect to such
Revolving Loan, and (iii) no Default or Event of Default shall have occurred
which is then continuing. The inability of the Lender to cause a payment of any
accrued interest owing on the Revolving Loans on any Interest Payment Date as of
the respective due date thereof in accordance with the preceding sentence shall
not in any way whatsoever effect the Borrower's obligation to otherwise pay such
amounts in accordance with the applicable terms hereof or any other Loan
Documents.

         2.7 Application of Payments and Prepayments.

                  (a) Except as otherwise provided in Sections 2.5(a) and (b)
hereof, prepayments on the Revolving Note shall be applied to payment of the
aggregate unpaid principal amounts of the Revolving Note, with the balance of
any such prepayments, if any, being applied to accrued interest. Payments of
accrued interest on the Revolving Note in accordance with Section 2.6(c) hereof
shall be applied to the aggregate accrued interest then outstanding under the
Revolving Note, while payment by the Borrower of the aggregate principal amount
outstanding under the Revolving Note on the Revolving Loan Maturity Date shall
be applied to principal.

                  (b) All sums payable by the Borrower to the Lender hereunder
or pursuant to the Revolving Note shall be payable in United States dollars in
immediately available funds not later than 12:00 noon on the date such payment
or prepayment is due and shall be made without set-off, counterclaim or
deduction of any kind. Any such payment or prepayment received and accepted by
the Lender after 12:00 noon shall be considered for all purposes (including the
payment of interest, to the extent permitted by law) as having been made on the
next succeeding Business Day. All such payments or prepayments shall be made at
the Principal Office. If any payment or prepayment becomes due and payable on a
day which is not a Business Day, then the date for the payment thereof shall be
extended to the next succeeding Business Day and interest shall be payable
thereon at the then applicable rate per annum during such extension

         2.8 Interest Rates for Revolving Loans.

                  (a) Subject to Section 10.6 hereof, the Revolving Note shall
bear interest on their respective outstanding principal balances at the
Alternate Base Rate; provided, that (1) all past due principal and interest
shall bear interest at the Past Due Rate, which shall be payable on demand, and
(2) subject to the provisions hereof, the Borrower shall have the option of
having all or any portion of the principal balances from time to time
outstanding under the Revolving



CREDIT AGREEMENT - Page 26
<PAGE>   35

Note bear interest until their respective maturities at a rate per annum equal
to the Adjusted LIBOR Rate (together with the Alternate Base Rate, individually
herein called an "Interest Option" and collectively called "Interest Options").
The records of the Lender with respect to Interest Options, Interest Periods and
the amounts of Revolving Loans to which they are applicable shall be binding and
conclusive, absent manifest error. Interest on the Revolving Loans shall be
calculated at the Alternate Base Rate, except where it is expressly provided
pursuant to this Agreement that the Adjusted LIBOR Rate is to apply.

                  (b) The Borrower shall have the right to designate or convert
its Interest Options in accordance with the provisions hereof. Provided no
Default or Event of Default has occurred and is continuing and subject to the
provisions of the last sentence of Subsection 2.8(a) hereinabove and of Section
2.9 hereof, the Borrower may elect to have the Adjusted LIBOR Rate apply or
continue to apply to all or any portion of the principal balances of the
Revolving Note. Each change in Interest Options shall be a conversion of the
rate of interest applicable to the specified portion of the Revolving Loans, but
such conversion alone shall not change the outstanding principal balance of the
Revolving Note. The Interest Options shall be designated or converted in the
manner provided below:

                           (1) The Borrower shall give the Lender notice by
         telephone, promptly confirmed by written notice (the "Rate Selection
         Notice") substantially in the form of Exhibit F hereto. Each such
         telephone and written notice shall specify the amount and type of
         borrowings which are the subject of the designation, if any; the amount
         and type of borrowings into which such borrowings are to be converted
         or for which an Interest Option is designated; the proposed date for
         the designation or conversion (which, in the case of conversion of
         LIBOR Borrowings, except as provided in Section 2.9 hereof, shall be
         the last day of the Interest Period applicable thereto) and the
         Interest Period or Periods, if any, selected by the Borrower. Such
         notice by telephone shall be irrevocable and shall be given to the
         Lender no later than the applicable Rate Selection Date. If (x) a new
         Revolving Loan is to be a LIBOR Borrowing, (y) an existing LIBOR
         Borrowing is maturing at the time that a new Revolving Loan is being
         requested and the Borrower is electing to have such existing portion of
         the outstanding principal balance of the Revolving Note going forward
         bear interest at the same Interest Option and for the same Interest
         Period as the new Revolving Loan, or (z) a portion of an Alternate Rate
         Borrowing is to be converted so as to bear interest at the same
         Interest Option and for the same Interest Period as the new Revolving
         Loan, then the Rate Selection Notice shall be included in the Request
         for Extension of Credit applicable to the new Revolving Loan, which
         shall be given to the Lender no later than the applicable Rate
         Selection Date.

                           (2) No more than three (3) LIBOR Borrowings and
         corresponding Interest Periods shall be outstanding at any one time.
         Each LIBOR Borrowing shall be in a minimum aggregate principal amount
         of at least $500,000, with any increases over such minimum amount being
         in integral aggregate multiples of $100,000.

                           (3) Principal included in any borrowing shall not be
         included in any other borrowing which exists at the same time.



CREDIT AGREEMENT - Page 27
<PAGE>   36

                           (4) Each designation or conversion shall occur on a
         Business Day.

                           (5) Except as provided in Section 2.9 hereof, no
         LIBOR Borrowing shall be converted on any day other than the last day
         of the applicable Interest Period.

                  (c) All interest and fees (including the Commitment Fee) will
be computed on the basis of a year of 360 days and actual days elapsed
(including the first day but excluding the last day) occurring in the period for
which payable, unless the effect of so computing shall be to cause the rate of
interest to exceed the Highest Lawful Rate.

         2.9 Special Provisions Applicable to LIBOR Borrowings.

                  (a) If, after the date of this Agreement, the adoption of any
applicable Legal Requirement or any change in any applicable Legal Requirement
or in the interpretation or administration thereof by any Governmental Authority
or compliance by the Lender with any request or directive (whether or not having
the force of law) of any Governmental Authority shall at any time make it
unlawful or impossible for the Lender to permit the establishment of or to
maintain any LIBOR Borrowing, the commitment of the Lender to establish or
maintain the Adjusted LIBOR Rate affected by such adoption or change shall
forthwith be canceled and the Borrower shall forthwith, upon demand by the
Lender to the Borrower, (1) convert the Adjusted LIBOR Rate with respect to
which such demand was made to the Alternate Base Rate; (2) pay all accrued and
unpaid interest to date on the amount so converted; and (3) pay any amounts
required to compensate the Lender for any additional cost or expense which the
Lender may incur as a result of such adoption of or change in such Legal
Requirement or in the interpretation or administration thereof and any
Consequential Loss which the Lender may incur as a result of such conversion to
the Alternate Base Rate. If, when the Lender so notifies the Borrower, the
Borrower has given a Rate Selection Notice specifying one or more borrowings of
the type with respect to which such demand was made but the selected Interest
Period or Interest Periods has not yet begun, such Rate Selection Notice shall
be deemed to be of no force and effect, as if never made, and the balance of the
Revolving Loans specified in such Rate Selection Notice shall bear interest at
the Alternate Base Rate until a different available Interest Option shall be
designated in accordance herewith.

                  (b) If the adoption of any applicable Legal Requirement or any
change in any applicable Legal Requirement or in the interpretation or
administration thereof by any Governmental Authority or compliance by the Lender
with any request or directive (whether or not having the force of law) from any
Governmental Authority shall at any time as a result of any portion of the
principal balance of the Revolving Note being maintained on the basis of the
Adjusted LIBOR Rate:

                           (1) subject the Lender (or make it apparent that the
         Lender is subject) to any tax (including any United States interest
         equalization tax), levy, impost, duty, charge, fee (collectively,
         "Taxes"), or any deduction or withholding for any Taxes on or from the
         payment due under any LIBOR Borrowing or other amounts due hereunder,
         other than income and franchise taxes of the United States and its

                           (2) change the basis of taxation of payments due from
         the Borrower to the Lender under any LIBOR Borrowing (otherwise than by
         a change in the rate of taxation of the overall net income of the
         Lender); or

                           (3) impose, modify, increase or deem applicable any
         reserve requirement (excluding that portion of any reserve requirement
         included in the calculation of the Statutory Reserves, special deposit
         requirement or similar requirement (including state law requirements
         and Regulation D)) imposed, modified, increased or deemed applicable by
         any Governmental Authority against assets held by the Lender, or
         against deposits or accounts in or for the account of the Lender, or
         against loans made by the Lender, or against any other funds,
         obligations or other Property owned or held by the Lender; or

                           (4) impose on the Lender any other condition
         regarding any LIBOR Borrowing;

and the result of any of the foregoing is to increase the cost to the Lender of
agreeing to make or of making, renewing or maintaining such borrowing on the
basis of the Adjusted LIBOR Rate, or reduce the amount of principal or interest
received by the Lender, then, upon demand by the Lender, the Borrower shall pay
to the Lender, from time to time as specified by the Lender, additional amounts
which shall compensate the Lender for such increased cost or reduced amount. The
Lender will promptly notify the Borrower in writing of any event, upon becoming
actually aware of it, which will entitle the Lender to additional amounts
pursuant to this paragraph. The Lender's determination of the amount of any such
increased cost, increased reserve requirement or reduced amount shall be
conclusive and binding, absent manifest error, provided that the calculation
thereof is set forth in reasonable detail in such notice.

         The Borrower shall have the right, if it receives from the Lender any
notice referred to in the preceding paragraph, upon three (3) Business Days'
notice to the Lender, either (i) to repay in full (but not in part) any
borrowing with respect to which such notice was given, together with any accrued
interest thereon, or (ii) to convert the Adjusted LIBOR Rate in effect with
respect to such borrowing to the Alternate Base Rate; provided, that any such
repayment or conversion shall be accompanied by payment of (x) the amount
required to compensate the Lender for the increased cost or reduced amount
referred to in the preceding paragraph; (y) all accrued and unpaid interest to
date on the amount so repaid or converted, and (z) any Consequential Loss which
may be incurred as a result of such repayment or conversion.

                  (c) If for any reason with respect to any Interest Period the
Lender shall have determined (which determination shall be conclusive and
binding upon the Borrower) that: (1) the Lender is unable through its customary
general practices to determine a rate at which the Lender is offered deposits in
United States dollars by prime banks in the London interbank market, in the
appropriate amount for the appropriate period, or by reason of circumstances
affecting the London interbank market, generally, the Lender is not being
offered deposits for the applicable Interest Period and in an amount equal to
the amount requested by the Borrower, or (2) the Adjusted LIBOR Rate will not
reflect the actual cost to the Lender of making and



CREDIT AGREEMENT - Page 29
<PAGE>   38

maintaining any LIBOR Borrowing hereunder for any proposed Interest Period, then
the Lender shall give the Borrower notice thereof and thereupon, (A) any Rate
Selection Notice previously given by the Borrower designating an Adjusted LIBOR
Rate which has not commenced as of the date of such notice from the Lender shall
be deemed for all purposes hereof to be of no force and effect, as if never
given, and (B) until the Lender shall notify the Borrower that the circumstances
giving rise to such notice from the Lender no longer exist, each Rate Selection
Notice requesting an Adjusted LIBOR Rate shall be deemed a request for an
Alternate Base Rate Borrowing, and each outstanding LIBOR Borrowing then in
effect shall be converted, without any notice to or from the Borrower, upon the
termination of the Interest Period then in effect, to an Alternate Base Rate
Borrowing.

                  (d) THE BORROWER HEREBY AGREES TO INDEMNIFY THE LENDER AGAINST
AND HOLD THE LENDER HARMLESS FROM ANY LOSS OR EXPENSE WHICH IT MAY INCUR OR
SUSTAIN AS A CONSEQUENCE OF ANY UNTIMELY PAYMENT (MANDATORY OR OPTIONAL) OR
DEFAULT BY THE BORROWER IN THE PAYMENT OF ANY PRINCIPAL AMOUNT OF OR INTEREST ON
THE NOTE, OR ANY FAILURE BY THE BORROWER TO CONVERT OR TO BORROW ANY LIBOR
BORROWING ON THE DATE SPECIFIED BY THE BORROWER, IN EACH CASE INCLUDING ANY
INTEREST PAYABLE BY THE LENDER TO THE LENDERS OF THE FUNDS OBTAINED BY IT IN
ORDER TO MAKE OR MAINTAIN ANY LIBOR BORROWING (OR ANY PORTION THEREOF), AND, TO
THE EXTENT NOT COVERED ABOVE, ANY CONSEQUENTIAL LOSS. THIS AGREEMENT SHALL
SURVIVE THE PAYMENT OF THE REVOLVING NOTE. A CERTIFICATE AS TO ANY ADDITIONAL
AMOUNTS PAYABLE TO THE LENDER PURSUANT TO THIS PARAGRAPH SUBMITTED BY THE LENDER
TO THE BORROWER SHALL BE CONCLUSIVE AND BINDING UPON THE BORROWER, ABSENT
MANIFEST ERROR, PROVIDED THE CALCULATION THEREOF IS SET FORTH IN REASONABLE
DETAIL IN SUCH NOTICE.

                  (e) If the Borrower requests quotes of the Adjusted LIBOR Rate
for different Interest Periods being considered for election by the Borrower,
the Lender will use reasonable efforts to provide such quotes to the Borrower
promptly. However, all such quotes provided shall be representative only and
shall not be binding on the Lender, nor shall they be determinative, directly or
indirectly, of any Adjusted LIBOR Rate or any component of any rate, nor will
the Borrower's failure to receive or the Lender's failure to provide any
requested quote or quotes either (1) excuse or extend the time for performance
of an obligation of the Borrower or for the exercise of any right, option or
election of the Borrower or (2) impose any duty or liability on the Lender. If
the Borrower requests a list of the Business Days in any calendar month, the
Lender will use reasonable efforts to provide such list promptly. However, any
such list provided shall be understood to identify only those days which the
Lender believes in good faith at the time such list is prepared will be the
Business Days for such month. The Lender shall not have any liability for any
failure to provide, delay in providing, error or mistake in or omission from,
any such quote or list.

                  (f) If the Lender has a LIBOR Lending Office which differs
from its Domestic Lending Office, all Revolving Loans advanced by the Lender's
LIBOR Lending Office shall be deemed to have been made by the Lender and the
obligation of the Borrower to repay such Revolving Loans shall nevertheless be
to the Lender and shall be deemed held by the Lender, to the extent of such
portions of the Revolving Loan, for the account of the Lender's LIBOR Lending
Office.



CREDIT AGREEMENT - Page 30
<PAGE>   39

                  (g) Notwithstanding any provision of this Agreement to the
contrary, the Lender shall be entitled to fund and maintain its funding of all
or any part of the Revolving Loans hereunder in any manner it sees fit, it being
understood, however, that for the purposes of this Agreement, all determinations
hereunder shall be made as if the Lender had actually funded and maintained its
portion of each LIBOR Borrowing during each Interest Period for the Revolving
Loans through the purchase of deposits having a maturity corresponding to such
Interest Period and bearing an interest rate equal to the LIBOR Rate for such
Interest Period.

                  (h) The Borrower's obligation to pay increased costs and
Consequential Loss with regard to each LIBOR Borrowing as specified in this
Section 2.9 hereof shall survive termination of this Agreement.

         2.10 Letters of Credit.

                  (a) Subject to the terms and conditions contained herein, the
Borrower shall have the right to utilize a portion of the Revolving Commitment
from time to time prior to the Revolving Loan Maturity Date to obtain from the
Lender one or more Letters of Credit for the account of the Borrower in such
amounts and in favor of such beneficiaries as the Borrower from time to time
shall request; provided, that in no event shall the Lender have any obligation
to issue any Letter of Credit if (i) the face amount of such Letter of Credit,
plus the Letter of Credit Exposure Amount at such time would exceed $500,000,
(ii) the face amount of such Letter of Credit, plus the aggregate of the
Lender's Current Sum at such time, would exceed the lesser of (1) the Revolving
Commitment or (2) the Availability, (iii) such Letter of Credit would have an
expiry date beyond the earlier to occur of (1) one month prior to the scheduled
Revolving Loan Maturity Date, (2) 90 days after the issuance date of such Letter
of Credit if such Letter of Credit is a documentary sight Letter of Credit or
(3) 365 days after the issuance date of such Letter of Credit if such Letter of
Credit is a standby Letter of Credit, (iv) such Letter of Credit is not in a
form and does not contain terms satisfactory to the Lender in its sole and
absolute discretion, (v) the Borrower have not executed and delivered such
Applications and other instruments and agreements relating to such Letter of
Credit as the Lender shall have requested, or (vi) an event has occurred and is
continuing which constitutes a Default or Event of Default.

                  (b) If requesting the issuance of any Letter of Credit, the
Borrower shall give at least three (3) Business Days' prior written notice to
the Lender, at its Domestic Lending Office, which written notice shall be the
requisite Application for a Letter of Credit on the Lender's customary form.

                  (c) The Borrower promises to pay to the order of the Lender
the amount of all Letter of Credit Advances. To effect repayment of any such
Letter of Credit Advance, the Lender shall automatically satisfy such Letter of
Credit Advance (subject to the terms and conditions of Sections 2.1 and 5.1
hereof) by making a Revolving Loan if (i) such Letter of Credit Advance is (and
such Revolving Loan is to be) made prior to the Revolving Loan Maturity Date,
(ii) the Availability would be equal to or greater than zero after giving effect
to such Revolving Loan and (iii) no Default or Event of Default shall have
occurred which is then continuing. If the Lender does not make a Revolving Loan
to satisfy such Letter of Credit Advance, each such letter of Credit Advance
shall be considered for all purposes as a demand



CREDIT AGREEMENT - Page 31
<PAGE>   40

obligation owing by the Borrower to the Lender, and each Letter of Credit
Advance shall bear interest from the date thereof at the Past Due Rate, without
notice of presentment, demand, protest or other formalities of any kind (said
past due interest on such Letter of Credit Advance being payable on demand). The
failure of the Lender to affect repayment of any such Letter of Credit Advance
in accordance with the preceding sentences shall not in any way whatsoever
affect the Borrower's obligation to pay each Letter of Credit Advance on demand
and to pay interest at the Past Due Rate on the amount of unreimbursed Letter of
Credit Advance. All rights, powers, benefits and privileges of this Agreement
with respect to the Revolving Note, all security therefor (including the
Collateral) and guaranties thereof (including the Guaranties) and all
restrictions, provisions for repayment or acceleration and all other covenants,
warranties, representations and agreements of the Borrower contained in this
Agreement with respect to the Revolving Note shall apply to such Letter of
Credit Advances.

                  (d) In consideration of the issuance of each Letter of Credit
pursuant to the provisions of this Section 2.10, the Borrower agrees to pay
(subject to Section 10.6 hereof) to the Lender a letter of credit fee (computed
on the basis of the actual number of days elapsed in a year composed of 360
days) in an amount equal to, (i) with respect to each documentary letter of
credit, the product of (a) the Applicable Margin in effect for LIBOR Borrowings
for the applicable period times (b) the undrawn upon amount of the applicable
Letter of Credit, and (ii) with respect to each standby letter of credit, the
product of (a) the Applicable Margin in effect for LIBOR Borrowings for the
applicable period plus 200 basis points times (b) the undrawn upon amount of the
applicable Letter of Credit, with each letter of credit fee to commence to
accrue as of the date of issuance of such Letter of Credit and to be effective
as to any reductions in the undrawn amount of such Letter of Credit as of the
date of any such reduction (whether resulting from payments thereunder by the
Lender, by agreement of the beneficiary thereunder or automatically by the terms
of such Letter of Credit), and each letter of credit fee shall cease to accrue
(except with respect to interest at the Past Due Rate on any unpaid portion
thereof) on the date that such Letter of Credit expires, is returned to the
Lender undrafted upon by the beneficiary thereof or is fully paid by the Lender.
Said letter of credit fees shall be payable in arrears to the Lender at its
Principal Office in immediately available funds (i) on the first Business Day of
each calendar month that such Letter of Credit remains open, and (ii) on the
date that such Letter of Credit expires, is returned to the Lender undrafted
upon by the beneficiary thereof or is fully paid by the Lender. All past due
letter of credit fees shall bear interest at the Past Due Rate and shall be
payable upon demand by the Lender. The Borrower also hereby agrees to pay to the
Lender any and all other issuance, amendment, negotiation, and other normal and
customary fees which are charged by the Lender in connection with the issuance
or negotiation of any of Letter of Credit and the presentation or payment of any
draw under any such Letter of Credit, with all of such amounts being due and
payable to the Lender upon demand.

                  (e) The obligations of the Borrower under this Agreement in
respect of the Letters of Credit and all Letter of Credit Advances are absolute,
unconditional and irrevocable, shall be paid strictly in accordance with the
terms of this Agreement, under all circumstances whatsoever, including the
following circumstances:



CREDIT AGREEMENT - Page 32
<PAGE>   41

                           (1) any lack of validity or enforceability of this
         Agreement, any Letter of Credit or any Loan Document;

                           (2) any amendment or waiver of default under or any
         consent to departure from the terms of this Agreement or any Letter of
         Credit without the express prior written consent of the Lender;

                           (3) the existence of any claim, set-off, defense or
         other right which any beneficiary or any transferee of any Letter of
         Credit (or any entities for whom any such beneficiary or any such
         transferee may be acting), or any Person (other than the Lender) may
         have, whether in connection with this Agreement, the Letters of Credit,
         the transactions contemplated hereby or any unrelated transaction;

                           (4) any statement, draft, certificate, or any other
         document presented under any Letter of Credit proving to be forged,
         fraudulent, invalid or insufficient in any respect or any statement
         therein being untrue or inaccurate in any respect whatsoever; provided
         that the Lender will examine each document presented under each Letter
         of Credit to ascertain that such document appears on its face to comply
         with the terms thereof; and

                           (5) any other circumstance or happening whatsoever,
         whether or not similar to any of the foregoing.

         In the event that any restriction or limitation is imposed upon or
         determined or held to be applicable to the Lender or the Borrower by,
         under or pursuant to any Legal Requirement now or hereafter in effect
         or by reason of any interpretation thereof by any Governmental
         Authority, which in the respective sole judgment of the Lender would
         prevent the Lender from legally incurring liability under a Letter of
         Credit issued or proposed to be issued hereunder, then the Lender shall
         give prompt written notice thereof to the Borrower, whereupon the
         Lender shall have no obligation to issue any additional Letters of
         Credit then or at any time thereafter. In addition, if as a result of
         any Regulatory Change which imposes, modifies or deems applicable (x)
         any tax, reserve, special deposit or similar requirement against any
         Letters of Credit issued or participated to by the Lender, (y) any fee,
         expense or assessment against the Letters of Credit issued by the
         Lender for deposit insurance, or (z) any other charge, expense or
         condition which increases the actual cost to the Lender of issuing or
         maintaining such Letters of Credit, or reduces any amount receivable by
         the Lender hereunder in respect of any Letter of Credit or any
         participation therein (which increase in cost, or reduction in amount
         receivable, shall be the result of the Lender's reasonable allocation
         of the aggregate of such increases or reductions resulting from such
         event), then the Borrower (subject to Section 10.6 hereof) shall pay to
         the Lender, upon demand and from time to time, amounts sufficient to
         compensate such Person for each such increase from the effective date
         of such increase to the date of demand therefor. Each such demand shall
         be accompanied by a certificate setting forth in reasonable detail the
         calculation of the amount then being demanded in accordance with the
         preceding sentence and each such certificate shall be conclusive absent
         manifest error.



CREDIT AGREEMENT - Page 33
<PAGE>   42

                  (f) THE BORROWER HEREBY INDEMNIFIES AND HOLDS HARMLESS LENDER
FROM AND AGAINST ANY AND ALL CLAIMS AND DAMAGES, LOSSES, LIABILITIES, COSTS OR
EXPENSES WHICH LENDER MAY INCUR (OR WHICH MAY BE CLAIMED AGAINST LENDER BY ANY
PERSON WHATSOEVER) IN CONNECTION WITH THE EXECUTION AND DELIVERY OR TRANSFER OF
OR PAYMENT OR FAILURE TO PAY UNDER ANY LETTER OF CREDIT; PROVIDED, THAT THE
BORROWER SHALL NOT BE REQUIRED TO INDEMNIFY LENDER FOR ANY CLAIMS, DAMAGES,
LOSSES, LIABILITIES, COSTS OR EXPENSES TO THE EXTENT, BUT ONLY TO THE EXTENT,
CAUSED BY (I) THE WILLFUL MISCONDUCT OR GROSS NEGLIGENCE OF THE PARTY SEEKING
INDEMNIFICATION OR (II) LENDER'S FAILURE TO PAY UNDER ANY LETTER OF CREDIT AFTER
THE PRESENTATION TO IT OF A REQUEST REQUIRED TO BE PAID UNDER APPLICABLE LAW.
NOTHING IN THIS SECTION 2.10(F) IS INTENDED TO LIMIT THE OBLIGATIONS OF THE
BORROWER UNDER ANY OTHER PROVISION OF THIS AGREEMENT.

         2.11 Recapture. If on any Interest Payment Date the Lender does not
receive payment in full of interest computed at the Alternate Base Rate and/or
the Adjusted LIBOR Rate, as applicable (computed without regard to any
limitation by the Highest Lawful Rate) because the sum of the Alternate Base
Rate and/or the Adjusted LIBOR Rate, as applicable (so computed) exceeds or has
exceeded the Highest Lawful Rate applicable to the Lender, the Borrower shall
pay to the Lender, in addition to interest otherwise required, on each Interest
Payment Date thereafter, the Excess Interest Amount (calculated as of each such
subsequent Interest Payment Date); provided that in no event shall the Borrower
be required to pay, for any computation period, interest at a rate exceeding the
Highest Lawful Rate applicable to the Lender during such period. As used herein,
the term "Excess Interest Amount" shall mean, on any day, the amount by which
(a) the amount of all interest which would have accrued prior to such day on the
outstanding principal of the Revolving Note (had the Alternate Base Rate and/or
the Adjusted LIBOR Rate, as applicable, at all times been in effect without
limitation by the Highest Lawful Rate applicable to the Lender) exceeds (b) the
aggregate amount of interest actually paid to the Lender on the Revolving Note
on or prior to such day.

         2.12 Use of Proceeds. The proceeds of the Revolving Loans will be used
to (i) refinance the existing Indebtedness of Tidel Engineering, Inc. to the
Lender, and (ii) finance general working capital needs of Borrower.

3. Term Loan; Term Note; Payments; Prepayments; Interest Rates.

         3.1 Term Loan Commitment. Subject to the terms and conditions hereof,
the Lender agrees to continue the Prior Term Loan in the form of a Term Loan to
the Borrower and to the Ultimate Parent, as co-borrowers, on the Closing Date
until, but not including, the Term Loan Maturity Date, in a principal amount up
to, but not exceeding the Term Loan Commitment.



CREDIT AGREEMENT - Page 34
<PAGE>   43

         3.2 Mandatory and Voluntary Prepayments.

                  (a) The Borrower and the Ultimate Parent shall have the right,
at their option and subject to the requirements of Section 2.4, to prepay the
Term Loan as provided in this Section 3.2. Any prepayment under this subsection
shall applied to the prepayment of the aggregate unpaid principal amount of the
Term Note. Prepayment under this subparagraph (a) shall be subject to the
following additional conditions:

                           (1) In no event shall the Term Note be partially
         prepaid.

                           (2) Prepayment applied to the Term Note may be made
         on any Business Day, provided, that (i) the Borrower shall have given
         the Lender at least five (5) Business Days' prior irrevocable written
         or telecopied notice of such prepayment, specifying the principal
         amount of the Term Note to be prepaid, which shall be the entire amount
         of the outstanding principal of the Term Note, and (ii) if such
         prepayment is made on any day other than the Term Loan Maturity Date,
         the Borrower shall pay directly to the Lender, on the date of such
         prepayment, the Consequential Loss as a result of such prepayment.

                  (b) Notice of any prepayment having been given, the principal
amount specified in such notice, together with interest thereon to the date of
prepayment, shall be due and payable on such prepayment date.

         3.3 Term Note; Payments.

                  (a) The Term Loan made by the Lender to the Borrower shall be
evidenced by a Term Note dated as of the Closing Date, delivered and payable to
the Lender in a principal amount equal to the Term Loan Commitment as of the
Term Loan Closing Date.

                  (b) Principal payments in the amount of Thirty-Two Thousand
and No/100 Dollars ($32,000.00), each, shall be due and payable quarterly, on
each Term Loan Payment Date. The remaining outstanding principal balance of the
Term Loan, as evidenced by the Term Note, shall mature and be fully due and
payable on the Term Loan Maturity Date.

                  (c) Subject to Section 10.6 hereof, the Borrower hereby agrees
to pay accrued interest on the unpaid principal balance of the Term Loan on each
Term Loan Payment Date. After the Term Loan Maturity Date, accrued and unpaid
interest on the Term Loan shall be payable on demand.

                  (d) To effect payment of accrued interest owing on the Term
Loan as of the Interest Payment Dates, subject to the provisions of Sections 2.1
and 5.1 hereof, the Lender may, but shall not be obligated to, make a Revolving
Loan to pay in full the amount of accrued interest owing and payable on the Term
Loan as of the respective Interest Payment Date if (i) such Revolving Loan is to
be made prior to the Revolving Loan Maturity Date, (ii) the Availability would
be equal to or greater than zero after giving effect to the Revolving Loan, and
(iii) no Default or Event of Default shall have occurred which is then
continuing. The inability



CREDIT AGREEMENT - Page 35
<PAGE>   44

of the Lender to cause a payment of any accrued interest owing on the Term Loan
on any Interest Payment Date as of the respective due date thereof in accordance
with the preceding sentence shall not in any way whatsoever effect the
Borrower's and the Ultimate Parent's obligation to otherwise pay such amounts in
accordance with the applicable terms hereof or any other Loan Documents.

         3.4 Application of Payments and Prepayments.

                  (a) Prepayment on the Term Note shall be applied to payment of
the aggregate unpaid principal amount of the Term Note, with the balance of any
such prepayments, if any, being applied to accrued interest. Payments of accrued
interest on the Term Note in accordance with Section 3.3(c) hereof shall be
applied to the aggregate accrued interest then outstanding under the Term Note,
while payment by the Borrower of the aggregate principal amount outstanding
under the Term Note on the Term Loan Maturity Date shall be applied to
principal.

                  (b) All sums payable by the Borrower to the Lender hereunder
or pursuant to the Term Note shall be payable in United States dollars in
immediately available funds not later than 12:00 noon on the date such payment
or prepayment is due and shall be made without set-off, counterclaim or
deduction of any kind. Any such payment or prepayment received and accepted by
the Lender after 12:00 noon shall be considered for all purposes (including the
payment of interest, to the extent permitted by law) as having been made on the
next succeeding Business Day. All such payments or prepayments shall be made at
the Principal Office. If any payment or prepayment becomes due and payable on a
day which is not a Business Day, then the date for the payment thereof shall be
extended to the next succeeding Business Day and interest shall be payable
thereon at the then applicable rate per annum during such extension.

         3.5 Interest Rate for Term Loan.

                  (a) Subject to Section 10.6 hereof, the Term Note shall bear
interest on its outstanding principal balances at a rate per annum equal to the
Fixed Rate.

                  (b) All interest will be computed on the basis of a year of
360 days and actual days elapsed (including the first day but excluding the last
day) occurring in the period for which payable, unless the effect of so
computing shall be to cause the rate of interest to exceed the Highest Lawful
Rate.

         3.6 Special Provisions Applicable to the Term Loan. THE BORROWER AND
ULTIMATE PARENT HEREBY AGREE TO INDEMNIFY THE LENDER AGAINST AND HOLD THE LENDER
HARMLESS FROM ANY LOSS OR EXPENSE WHICH IT MAY INCUR OR SUSTAIN AS A CONSEQUENCE
OF ANY UNTIMELY PAYMENT (MANDATORY OR OPTIONAL) OR DEFAULT BY THE BORROWER OR
THE ULTIMATE PARENT IN THE PAYMENT OF ANY PRINCIPAL AMOUNT OF OR INTEREST ON THE
TERM NOTE, INCLUDING ANY INTEREST PAYABLE BY THE LENDER TO THE LENDERS OF THE
FUNDS OBTAINED BY IT IN ORDER TO MAKE OR MAINTAIN THE TERM LOAN (OR ANY PORTION
THEREOF), AND, TO THE EXTENT NOT COVERED ABOVE, ANY CONSEQUENTIAL LOSS. THIS
AGREEMENT SHALL SURVIVE THE PAYMENT OF THE TERM NOTE. A CERTIFICATE AS TO ANY
ADDITIONAL AMOUNTS PAYABLE TO THE LENDER PURSUANT TO THIS PARAGRAPH



CREDIT AGREEMENT - Page 36
<PAGE>   45

SUBMITTED BY THE LENDER TO THE BORROWER AND ULTIMATE PARENT SHALL BE CONCLUSIVE
AND BINDING UPON THE BORROWER AND ULTIMATE PARENT, ABSENT MANIFEST ERROR,
PROVIDED THE CALCULATION THEREOF IS SET FORTH IN REASONABLE DETAIL IN SUCH
NOTICE.

         3.7 Use of Proceeds. The proceeds of the Term Loan will be used to
refinance the existing Indebtedness of Ultimate Parent and Tidel Engineering,
Inc. to the Lender.

4. Collateral.

         4.1 Security Documents. The Loans and all other Obligations shall be
secured by Collateral described in the Security Documents and are entitled to
the benefits thereof. The Borrower shall duly execute and deliver the Security
Documents, all consents of third parties necessary to permit the effective
granting of the Liens created thereby, financing statements pursuant to the
Uniform Commercial Code and other documents, all in Proper Form, as may be
reasonably required by the Lender to grant to the Lender a valid, perfected and
enforceable first priority Lien on and security interest in the Collateral
(subject only to the Liens permitted under Section 8.2 hereof).

         4.2 Filing and Recording. The Borrower shall, at its sole cost and
expense, cause all financing statements and other Security Documents pursuant to
this Agreement to be duly recorded and/or filed or otherwise perfected in all
places necessary, in the opinion of the Lender, and take such other actions as
the Lender may reasonably request, in order to perfect and protect the Liens of
the Lender in the Collateral. The Borrower, to the extent permitted by law,
hereby authorizes the Lender to file any financing statement in respect of any
Lien created pursuant to the Security Documents which may at any time be
required or which, in the opinion of the Lender, may at any time be desirable,
although the same may have been executed only by the Lender or, at the option of
the Lender, to sign such financing statement on behalf of the Borrower and file
the same, and the Borrower hereby irrevocably designates the Lender, its agent,
representatives and designees as its agent and attorney-in-fact for this
purpose. In the event that any re-recording or refiling thereof (or the filing

creation) except as may be stated in the invoice relating thereto or discounts
and allowances as may be customary in the Borrower's business; (d) none of the
transactions underlying or giving rise to any Eligible Receivable shall violate
any applicable state or federal laws or regulations, and all documents relating
to any Receivable shall be legally sufficient under such laws or regulations and

such contract shall be assigned to the Lender and notice thereof given under the
Federal Assignment of Claims Act; (j) it will, immediately upon learning
thereof, report to the Lender any material loss or destruction of, or
substantial damage to, any of the Collateral, and any other matters adversely
affecting the value, enforceability or collectibility of any of the Collateral;
(k) if any amount payable under or in connection with any Receivable is
evidenced by a promissory note or other instrument, as such terms are defined in
the Uniform Commercial Code, such promissory note or instrument shall be
immediately pledged, endorsed, assigned and delivered to the Lender as
additional collateral; (l) it shall not re-date any invoice or sale or make
sales on extended dating beyond that customary in the industry; and (m) it shall
not be entitled to pledge the Lender's credit on any purchases or for any
purpose whatsoever.

         6.21 Y2K Representation. Unless otherwise disclosed to the Lender, as
of no later than June 30, 1999, on the basis of a comprehensive review and
assessment of Borrower's systems and equipment and inquiry made of Borrower's
material suppliers, vendors and customers, Borrower's management will be of the
view that the "Year 2000 problem" (that is, the inability of computer, as well
as embedded microchips in non-computing devices, to perform date-sensitive
functions with respect to certain dates prior to and after December 31, 1999)
(the "Year 2000 Problem"), including costs of remediation, will not result in a
material adverse change in the operations, business, properties, condition
(financial or otherwise) or prospects of Borrower. By no later than June 30,
1999, Borrower will have developed feasible contingency plans adequately to
ensure uninterrupted and unimpaired business operation in the event of failure
of its own or a third party's systems or equipment due to the Year 2000 Problem,
including those of vendors, customers, and suppliers, as well as a general
failure of or interruption in its communications and delivery infrastructure.

the Lender under the terms of the Lockbox Agreements or in such other manner as
the Lender may direct. Prior to the implementation of the procedures discussed

the Lender is irrevocably authorized, in accordance with the terms of the
implementation and processing instructions for the applicable Lockbox
Agreement(s), to cause all such remittances on all Receivables to be promptly
deposited in such account or accounts designated by the Lender. All remittances
and payments that are deposited in accordance with the foregoing will be
immediately applied by the Lender to reduce the outstanding balance of the
Revolving Loans, subject to the continued accrual of interest on the Revolving
Loan balances to which such remittances and payments are applied for one (1)

exchanges, money orders or otherwise) to be promptly deposited in precisely the
form received (but with any endorsements of the Borrower or the applicable
Subsidiary necessary for deposit or collection) in the account or accounts
designated by the Lender in accordance with the provisions of Section 7.15(b)
above.

                  (d) In addition to the financial reporting requirements set

the date of such Receivables report.

                  (e) If and when the daily collection procedures discussed in
Section 7.15(b) above are implemented in accordance with the provisions thereof,
such daily collection procedures shall thereafter continue to be in effect until
the end of the fiscal quarter of the Borrower during which all existing Defaults
and Events of Default, if applicable, shall have been cured to the satisfaction
of the Lender and Availability shall have increased to an amount equal to or
greater than $50,000, if applicable.

         7.16 Additional Receivables Documentation. In addition to the

of the Collateral. The Borrower's failure 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.

exercise and no delay on the part of the Lender in exercising any right or power
under any Loan Document or at law or in equity shall operate as a waiver

the abandonment or discontinuance of steps to enforce any such right or power,
preclude any further or other exercise thereof or the exercise of any other
right or power. No course of dealing between the Borrower and the Lender shall
operate as a waiver of any right or power of the Lender. Subject to the
provisions of Section 10.11 hereof, no amendment, modification or waiver of any
provision of this Agreement or any other Loan Document, nor any consent to any
departure therefrom, shall be effective unless the same is in writing and signed
by the Person against whom it is sought to be enforced, and then it shall be
effective only in the specific instance and for the purpose for which given. No
notice to or demand on the Borrower or any other Person shall entitle the
Borrower or any other Person to any other or further notice or demand in similar
or other circumstances.

and either (i) delivered against receipt therefor, (ii) mailed by registered or

to the intended recipient at the "Address for Notices" specified below its name
on the signature pages hereof. The Borrower or Ultimate Parent may change its
address for purposes hereof by providing written notice of such address change
to the Lender in accordance with the provisions of this Section 10.2, with any
such change in address only being effective ten (10) Business Days after such
change of address has been deemed given in accordance with the provisions
hereof. Notices shall be deemed to have been given (whether actually received or
not) when delivered (or, if mailed, on the next Business Day); however, the
notices required or permitted by Sections 2.2(b) and 5.1(a) hereof shall be
effective only when actually received by the Lender.

         10.3 Governing Law. UNLESS OTHERWISE SPECIFIED THEREIN, EACH LOAN

         10.4 Survival; Parties Bound. All representations, warranties,
covenants and agreements made by or on behalf of the Borrower in connection
herewith shall survive the execution and delivery of the Loan Documents, shall
not be affected by any investigation made by any Person, and shall bind the

benefit of the successors and assigns of the Lender, provided that the
undertaking of the Lender hereunder to make Loans to the Borrower and to issue
Letters of Credit for the



CREDIT AGREEMENT - Page 64
<PAGE>   73

account of the Borrower shall not inure to the benefit of any successor or
assign of the Borrower. The term of this Agreement shall be until the final
maturity of the Notes and the payment of all amounts due under the Loan
Documents.

         10.5 Counterparts. This Agreement may be executed in several identical

counterpart, when so executed and delivered, shall constitute an original
instrument, and all such separate counterparts shall constitute but one and the
same instrument.

         10.6 Limitation of Interest. The Borrower and the Lender intend to
strictly comply with all applicable laws, including applicable usury laws, if
any. Accordingly, the provisions of this Section 10.6 shall govern and control
over every other provision of this Agreement or any other Loan Document which
conflicts or is inconsistent with this Section, even if such provision declares
that it controls. As used in this Section, the term "interest" includes the
aggregate of all charges, fees, benefits or other compensation which constitute
interest under applicable law, provided that, to the maximum extent permitted by
applicable law, (a) any non-principal payment shall be characterized as an
expense or as compensation for something other than the use, forbearance or
detention of money and not as interest, and (b) all interest at any time
contracted for, reserved, charged or received shall be amortized, prorated,
allocated and spread, in equal parts during the full term of the Loans and the
Commitments. In no event shall the Borrower or any other Person be obligated to
pay, or the Lender have any right or privilege to reserve, receive or retain,
(Y) any interest in excess of the maximum amount of non-usurious interest
permitted under the laws of the United States or of any state, if any, which are
applicable to the Lender, or (Z) total interest in excess of the amount which
the Lender could lawfully have contracted for, reserved, received, retained or
charged had the interest been calculated for the full term of the Loans at the
Highest Lawful Rate, if any, applicable to the Lender. On each day, if any, that
the sum of the Alternate Base Rate or the Adjusted LIBOR Rate, as applicable,
and the Applicable Margin, or any other applicable rate called for under any
other Loan Document exceeds the Highest Lawful Rate, if any, applicable to the
Lender, the rate at which interest shall accrue for the applicable type of
borrowing owing to the Lender shall automatically be fixed by operation of this
sentence at the Highest Lawful Rate applicable to the Lender for that day, and
shall remain fixed at the Highest Lawful Rate applicable to the Lender for each
day thereafter until the total amount of interest accrued and owing to the
Lender equals the total amount of interest which would have accrued on such
borrowing owing to the Lender if there were no such ceiling rate as is imposed
by this sentence. Thereafter, interest shall accrue at the Alternate Base Rate
plus the Applicable Margin, the Adjusted LIBOR Rate plus the Applicable Margin
or such other applicable rate, respectively, unless and until the sum of the
Alternate Base Rate and the Applicable Margin, the sum of the Adjusted LIBOR
Rate and the Applicable Margin or such other applicable rate (whichever is
applicable to the situation) again exceeds the Highest Lawful Rate applicable to
the Lender when the provisions of the immediately preceding since shall again
automatically operate to limit the interest accrual rate. The daily interest
rates to be used in calculating interest at the Highest Lawful Rate for the
Lender shall be determined by dividing the applicable Highest Lawful Rate, if
any, for the Lender per annum by the number of days in the calendar year for
which such calculation is being made. None of the terms and provisions contained
in this Agreement or in any other Loan Document which directly or indirectly
relate to interest shall ever be construed without reference to this Section
10.6, or be construed to create a



CREDIT AGREEMENT - Page 65
<PAGE>   74

contract to pay the Lender for the use, forbearance or detention of money at an
interest rate in excess of the Highest Lawful Rate applicable to the Lender. If
the term of any Loans or any of the Notes is shortened by reason of acceleration
of maturity as a result of any Default or Event of Default or by any other
cause, or by reason of any required or permitted prepayment, and if for that (or
any other) reason the Lender at any time is owed or receives (and/or has
received) interest in excess of interest calculated at the Highest Lawful Rate
applicable to the Lender, then and in any such event all of any such excess
interest owed to or received by the Lender shall be canceled automatically as of
the date of such acceleration, prepayment or other event which produces the
excess, and, if such excess interest has been paid to the Lender, it shall be
credited pro tanto against the then-outstanding principal balance of the
Borrower's obligations to the Lender, effective as of the date or dates when the
event occurs which causes it to be excess interest, until such excess is
exhausted or all of such principal has been fully paid and satisfied, whichever
occurs first, and any remaining balance of such excess shall be promptly
refunded to its payor. To the extent the Laws of the State of Texas are
applicable for purposes of determining the "Highest Lawful Rate," such term
shall mean the "weekly ceiling" from time to time in effect under Article lD.
003, Title 79, Revised Civil Statutes of Texas, as amended, or, if permitted by
applicable Law and effective upon the giving of the notices required by such
Article lD. 103 and under the Texas Finance Code (or effective upon any other
date otherwise specified by applicable Law), the "monthly ceiling," the
"quarterly ceiling" or "annualized ceiling" from time to time in effect under
such Chapter lD of the Texas Credit Title, whichever that the Lender shall elect
to substitute for the "weekly ceiling," and vice versa, each such substitution
to have the effect provided in such Chapter lD of the Texas Credit Title; and
the Lender shall be entitled to make such election from time to time and one or
more times and, without notice to Borrower, to leave any such substitute rate in
effect for subsequent periods in accordance with Chapter lD of the Texas Credit
Title. Pursuant to Article 15.10(b) of Chapter 15, Subtitle 79, Revised Civil
Statutes of Texas, 1925, as amended, and pursuant to Chapter 346.004 of the
Texas Finance Code, as amended, Borrower agrees that Chapter 15 of the Texas
Credit Title and Chapter 346 of the Texas Finance Code (which regulates certain
revolving credit loan accounts and revolving tri-party accounts) shall not
govern or in any manner apply to the Obligations.

         10.7 Survival. The obligations of the Borrower under Sections 2.3,
2.4(b), 2.9, 2.10(f), 10.9, 10.10 and 10.17 hereof shall survive the repayment
of the Loans, the termination of the Commitments and the cancellation or
expiration of the Letters of Credit.

         10.8 Captions. The headings and captions appearing in the Loan
Documents have been included solely for convenience and shall not be considered
in construing the Loan Documents.

         10.9 Expenses, Etc. Whether or not any Loan is ever made or any Letter
of Credit ever issued, the Borrower agrees to pay or reimburse on demand the
Lender for paying: (a) the reasonable fees and expenses of Hughes & Luce,
L.L.P., counsel to the Lender or any other legal counsel engaged by the Lender,

other charges incurred in connection with any filing, registration, recording or
perfection of any security interest contemplated by this Agreement, any other
Loan Document or any document referred to herein or therein, and the cost of
title insurance; and (e) reasonable and documented expenses of due diligence
incurred prior to or as of the Closing Date.

         10.10 Indemnification. THE BORROWER AGREES TO INDEMNIFY THE LENDER AND
EACH AFFILIATE THEREOF AND THEIR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES,
COUNSEL OR AGENTS FROM, AND HOLD EACH OF THEM HARMLESS AGAINST, ANY AND ALL
LOSSES, LIABILITIES (INCLUDING ENVIRONMENTAL LIABILITIES), CLAIMS (INCLUDING
ENVIRONMENTAL CLAIMS) OR DAMAGES TO WHICH ANY OF THEM MAY BECOME SUBJECT,
INSOFAR AS SUCH LOSSES, LIABILITIES, CLAIMS OR DAMAGES ARISE OUT OF OR RESULT

AGREES TO REIMBURSE THE LENDER, AND EACH AFFILIATE THEREOF AND THEIR RESPECTIVE
DIRECTORS, OFFICERS, EMPLOYEES, COUNSEL AND AGENTS, UPON DEMAND FOR ANY EXPENSES
(INCLUDING LEGAL FEES) INCURRED IN CONNECTION WITH ANY SUCH INVESTIGATION OR
PROCEEDING, AND WHETHER ANY SUCH LOSS, LIABILITY, CLAIM OR DAMAGE RESULTS FROM
THE NEGLIGENCE OF ANY SUCH INDEMNIFIED PERSON; BUT EXCLUDING ANY SUCH LOSSES,

         10.11 Amendments, Waivers, Etc. No amendment, modification or waiver of
any provision of this Agreement, any of the Notes or any other Loan Document,
nor any consent to any departure by the Borrower therefrom, shall in any event
be effective unless the same shall be or consented to by the Lender and the
Borrower, and each such waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given.

         10.12 Successors and Assigns.

                  (a) This Agreement shall be binding upon and inure to the
benefit of the Borrower and the Lender and their respective successors and
permitted assigns. The Borrower may not assign or transfer any of its rights or
obligations hereunder without the prior written consent of the Lender.

                  (b) The Lender may assign to one or more Persons all or a
portion of its interests, rights and obligations under this Agreement or may

participation or proposed assignment or participation pursuant to this Section
10.12, disclose to the assignee or participant or proposed assignee or
participant, any information relating to the Borrower furnished to the Lender by

such proposed assignee or participant to agree in writing to keep confidential
all information with respect to the Borrower furnished to it by the Lender in
connection with any proposed assignment or participation (other than information
generally available to the public or otherwise available to the Lender on a
non-confidential basis).

                  (d) Notwithstanding anything herein to the contrary, the
Lender may pledge and assign all or any portion of its rights and interests
under the Loan Documents to any Federal Reserve Bank.

         10.13 Entire Agreement. This Agreement and the other Loan Documents
embody the entire agreement and understanding among the Borrower and the Lender
relating to the subject matter hereof and supersedes all prior proposals,
agreements and understandings relating to the subject matter hereof. Any

Documents of even date herewith.

         10.14 Severability. If any provision of any Loan Documents shall be

validity, legality and enforceability of the remaining provisions shall not be
affected or impaired thereby.



CREDIT AGREEMENT - Page 68
<PAGE>   77

         10.15 Disclosures. Every reference in the Loan Documents to disclosures
of the Borrower to the Lender in writing, to the extent that such references
refer to disclosures at or prior to the execution of this Agreement, shall be
deemed strictly to refer only to written disclosures delivered to the Lender in
an orderly manner prior to or concurrently with the execution hereof.

         10.16 Taxes.

                  (a) As used in this Section 10.16, the following terms shall
have the following meanings:

                           (i) "Indemnifiable Tax" means any Tax, but excluding,
         in any case any Tax that (a) would not be imposed in respect of a
         payment to the Lender under this Agreement, under any of the Notes or
         under any of the other Loan Documents except for a present or former
         connection between the jurisdiction of the Governmental Authority
         imposing such Tax and the Lender (or a shareholder or other Person with
         an interest in the Lender), including a connection arising from the
         Lender's (or shareholder of the Lender or such other Person) being or
         having been citizen or resident of such jurisdiction, or being or
         having been organized, present or engaged in a trade or business in
         such jurisdiction, or having or having had a permanent establishment or
         fixed place of business in such jurisdiction, but excluding a
         connection arising solely from the Lender having executed, delivered,
         performed its obligations or received a payment under, or enforced,
         this Agreements, any of the Notes or any other Loan Documents, or (b)
         is imposed under United States federal income tax law or any state
         income tax law.

                           (ii) "Tax" means any present or future tax, levy,
         impost, duty, charge assessment or fee of any nature (including
         interest thereon and penalties and additions thereto) that is imposed
         by any Governmental Authority in respect of a payment to the Lender
         under this Agreement, under any of the Notes or under any of the other
         Loan Documents.

                  (b) If the Borrower is required by any Applicable Legal
Requirement to make any deduction or withholding for or on account of any
payment to be made by it under this Agreement, under any of the Notes or under
any other Loan Documents, then the Borrower shall (i) promptly notify the Lender
that is entitled to such payment of such requirement to so deduct or withhold
such Tax, (ii) pay to the relevant authorities the full amount required to be so
deducted or withheld, (iii) promptly forward to the Lender an official receipt
(or certified copies thereof), or other documentation reasonably acceptable to
the Lender holder, evidencing such payment to such Governmental Authorities and
(iv) if such Tax is an Indemnifiable Tax, pay, to the extent permitted by law,
to the Lender, in addition to whatever net amount of such payment is paid to the
Lender, such additional amount as is necessary to ensure that the total amount
actually received by the Lender (free and clear of Indemnifiable Tax) will equal
the full amount of the payment the Lender would have received had no such
deduction or withholding been required. If the Borrower pays any additional
amount to the Lender pursuant to the preceding sentence and the Lender shall
receive a refund of an Indemnifiable Tax with respect to which, in



CREDIT AGREEMENT - Page 69
<PAGE>   78

the good faith opinion of the Lender, such payment was made, the Lender shall
pay to the Borrower the amount of such refund promptly upon receipt thereof.

                  (c) In the event that any Governmental Authority notifies the
Borrower that it has improperly failed to withhold or deduct any Tax from a
payment received by the Lender under this Agreement, under any of the Notes or
under any other Loan Document, the Borrower agrees to timely and fully pay such
Tax to such Governmental Authority and the Lender shall, upon receipt of written
notice of such payment, immediately pay to the Borrower, an amount necessary in
order that the amount of such payment to the Borrower after payment of all Taxes
with respect to such payment, shall equal the amount that the Borrower paid to
such Governmental Authority pursuant to this clause (c).

                  (d) The Lender shall, upon request by the borrower, take
requested measures to mitigate the amount of Indemnifiable Tax required to be
deducted or withheld from any payment made by the Borrower under this Agreement,
under any of the Notes or under any other Loan Documents if such measures can,
in the sole and absolute opinion of the Lender, be taken without the Lender
suffering any economic, legal, regulatory or other disadvantage (provided,
however, that the Lender shall not be required to designate a funding office
that is not located in the United States of America).

                  (e) Notwithstanding the foregoing, in no event shall the
amount payable under this Section 10.16 (to the extent, if any, constituting
interest under applicable laws) together with all amounts constituting interest
under applicable laws and payable in connection with this Agreement or any of
the Notes, exceed the Highest Lawful Rate or the maximum amount of interest
permitted to be charged by applicable laws.

         10.17 Waiver of Claims. THE BORROWER HEREBY WAIVES AND RELEASES THE
LENDER FROM ANY AND ALL CLAIMS OR CAUSES OF ACTION WHICH THE BORROWER MAY OWN,
HOLD OR CLAIM IN RESPECT OF ANY OF THEM AS OF THE DATE HEREOF.

         10.18 Right of Setoff. Upon the occurrence and during the continuation
of any Event of Default, the Lender is hereby authorized at any time and from
time to time, without notice to the Borrower or any of the Guarantors (any such
notice being expressly waived by the Borrower and by the Guarantors by their
execution of a Guaranty or a Joinder Agreement), to setoff and apply any and all
deposits (general or special, time or demand, provisional or final, whether or
not such setoff results in any loss of interest or other penalty, and including
without limitation all certificates of deposit) at any time held, and any other
funds or property 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 or any such
Guarantor against any and all of the Indebtedness arising in connection with
this Agreement irrespective of whether or not the Lender will have made any
demand under this Agreement, any of the Notes or any other Loan Document. The
Borrower and each of the Guarantors (by their execution of a Guaranty or a
Joinder Agreement) also hereby grants to the Lender a security interest in and
hereby transfers, assigns, sets over, and conveys to the Lender, as security for
payment of all Loans and Letter of Credit Exposure Amount, all such deposits,
funds or property of the Borrower or any such Guarantor or Indebtedness of the
Lender to the Borrower or any such Guarantor. Should the right of the Lender to
realize funds in any manner



CREDIT AGREEMENT - Page 70
<PAGE>   79

set forth hereinabove be challenged and any application of such funds be
reversed, whether by court order or otherwise, the Lender shall make restitution
or refund to the Borrower or such Guarantor, as applicable. The Lender agrees to
promptly notify the Borrower after any such setoff and application, provided
that the failure to give such notice will not affect the validity of such setoff
and application. The rights of the Lender under this Section are in addition to
other rights and remedies (including without limitation other rights of setoff)
which the Lender may have.

         10.19 Waiver of Right to Jury Trial. EXCEPT AS PROHIBITED BY APPLICABLE
LAW, EACH PARTY HERETO HEREBY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN
RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN
CONNECTION WITH THIS AGREEMENT, THE NOTES, ANY OF THE OTHER LOAN DOCUMENTS OR
ANY TRANSACTIONS EVIDENCED THEREBY.

         10.20 Additional Provisions Regarding Collection of Receivables;
Control of Inventory and other Collateral.

                  (a) So long as the procedures discussed in Section 7.15(b)
hereof have been implemented and are continuing, the Borrower hereby constitutes
the Lender or the Lender's designee as the Borrower's attorney-in-fact with
power to endorse the Borrower's name upon any notes, acceptances, checks,
drafts, money orders or other evidence of payment of any Receivables or any
other Collateral that may come into its possession; to sign or endorse the
Borrower's name on any invoice, bill of lading or other title or ownership
documents relating to any Receivables or inventory, drafts against any customers
of the Borrower, assignments and verifications of Receivables and notices to
customers of the Borrower; to send verifications of Receivables; to notify the
U.S. Postal Service authorities to change the address for delivery of mail
addressed to the Borrower to such address as the Lender may designate at any
time after the occurrence of any Event of Default which is continuing and to do
all other acts and things necessary to carry out this Agreement. All acts of
said attorney or designee are hereby ratified and approved by the Borrower, and
said attorneys or designee shall not be liable for any acts of omission or
commission, for any error of judgment or for any mistake of fact or law,
provided that the Lender or its designee shall not be relieved of liability to
the extent it is determined by a final judicial decision that its act, error or
mistake constituted gross negligence or willful misconduct. The power of
attorney granted under this subparagraph is coupled with an interest and is
irrevocable until all of the Obligations are paid in full and this Agreement and
the Commitments are terminated.

                  (b) The Lender, without notice to or consent of the Borrower,
at any time after the occurrence and during the continuation of an Event of
Default; (i) 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
Receivables or any instruments or insurance applicable thereto and/or release
any account debtor thereon; (ii) is authorized and empowered to accept or direct
shipments of inventory and accept the return of the goods represented by any of

drafts and other instruments for the payment of money relating



CREDIT AGREEMENT - Page 71
<PAGE>   80

to the Receivables, and the Borrower hereby waives notice of presentment,
protest and non-payment of any instrument so endorsed.

                  (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 (except to the extent it is determined by a
final judicial decision that the Lender's act or omission constituted gross
negligence of willful conduct). 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
Receivables or any instrument received in payment thereof or for any damage
resulting therefrom (except to the extent it is determined by a final judicial
decision that the Lender's error, omission or delay constituted gross negligence
or willful misconduct). The Lender does not, by anything herein or in any
assignment or otherwise, assume any of the Borrower's obligations 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) Upon the occurrence and during the continuation of any
Event of Default: (i) if any of the Receivables includes a charge for any tax
payable to any governmental tax 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 charge the Borrower's
account therefor; and (ii) the Borrower shall notify the Lender if any
Receivables include any tax due to any such taxing authority and, in the absence
of such notice, the Lender shall have the right to retain the full proceeds of
such Receivables and shall not be liable for any taxes that may be due from the
Borrower by reason of the sale and delivery creating such Receivables.

                  (e) Upon the occurrence and continuation of any Event of
Default, the Lender may at any time and from time to time employ and maintain in
the premises of the Borrower a custodian selected by the Lender who shall have
full authority to do all acts necessary to protect the Lender's interests and to
report to the Lender thereon. The Borrower hereby agrees to cooperate with any
such custodian and to do so whatever the Lender may reasonably request to
preserve the Collateral. All costs and expenses incurred by the Lender by reason
of the employment of the custodian shall be charged to the Borrower's account
and added to the Obligations.

         10.21 Joint and Several Obligations. Notwithstanding anything to the
contrary contained herein or in any other Loan Documents, the Borrower and the
Guarantors are jointly and severally responsible for their respective
agreements, covenants, representations, warranties and obligations contained and
set forth in this Agreement or in any other Loan Document to which they are a
party.

         10.22 Venue; Service of Process. BORROWER, FOR ITSELF, ITS SUCCESSORS
AND ASSIGNS, HEREBY (A) IRREVOCABLY SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF
THE STATE AND FEDERAL COURTS OF THE STATE OF

THEREOF, (E) IF SERVICE OF PROCESS UPON THE REGISTERED AGENT IS UNSUCCESSFUL
AFTER ONE GOOD FAITH ATTEMPT, IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OUT
OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH LITIGATION BY THE MAILING OF
COPIES THEREOF BY CERTIFIED MAIL, RETURN RECEIPT REQUESTED, POSTAGE PREPAID, TO
SUCH BORROWER AT ITS ADDRESS SET FORTH HEREIN, AND (F) IRREVOCABLY AGREES THAT
ANY LEGAL PROCEEDING AGAINST LENDER ARISING OUT OF OR IN CONNECTION WITH THE
LOAN DOCUMENTS ON THE OBLIGATION SHALL BE BROUGHT IN THE DISTRICT COURTS OF
DALLAS COUNTY, TEXAS, OR IN THE UNITED STATES DISTRICT COURT FOR THE NORTHERN
DISTRICT OF TEXAS, DALLAS DIVISION. NOTHING HEREIN SHALL AFFECT THE RIGHT OF
LENDER TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST BORROWER IN
ANY JURISDICTION OR TO SERVE PROCESS IN ANY MANNER PERMITTED BY APPLICABLE LAW.

         10.23 No Other Agreements. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS
REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY
EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS BY THE PARTIES.
THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

                               Material Litigation

In August, 1998, Tidel Engineering, Inc. ("Tidel") filed a lawsuit (identified
as Cause No. DV98-06733 in the 192nd District Court of Dallas County, Texas)
against Defendant Hanco Systems, Inc. ("Hanco") for its failure to pay for goods
accepted pursuant to a distributor agreement between Tidel and Hanco. The amount
for which Tidel sued equals $298,492.03, plus accrued prejudgment interest in
the amount of $21,939.16. In response, Hanco removed the case to federal court
(identified as Civil Action No. 3-98CV2279-D, currently pending in the United
States District Court of the Northern District of Texas, Dallas Division). Hanco
subsequently filed counterclaims for the following causes of action: various
breaches of the distributor agreement, defamation, breach of warranty, negligent
misrepresentation, promissory estoppel, breach of implied promise, negligence
and violations of the Texas Deceptive Trade Practices Act. Hanco seeks to
recover $6.45 million in actual damages plus an unspecified amount in punitive
damages on their counterclaims. Tidel believes that these counterclaims are
wholly unsupported by the facts and were filed merely to avoid or delay paying
monies rightfully owed to Tidel.
