ITEM 1.  BUSINESS

                                   BACKGROUND

     Tidel Technologies, Inc. (the "Company") was incorporated under the laws of
     the State of Delaware in November 1987 under the name of American Medical
     Technologies, Inc., succeeding a corporation established in British
     Columbia, Canada in May 1984. The Company changed its name to Tidel
     Technologies, Inc. in July 1997.

     On September 30, 1992, the Company acquired all of the issued and
     outstanding capital stock of Tidel Engineering, Inc., a manufacturer of
     automated teller machines, electronic cash security systems and underground
     fuel storage monitoring and leak detection devices for a purchase price of
     $4,746,848. These operations currently represent the sole business of the
     Company.

                       DESCRIPTION OF BUSINESS ACTIVITIES

     The Company develops, manufactures, sells and supports products designed
     for specialty retail marketers, including automated teller machines and
     related software (the "ATM" products); electronic cash security systems
     (the "Timed Access Cash Controller" or "TACC" products); and underground
     fuel storage monitoring and leak detection devices (the "Environmental
     Monitoring System" or "EMS" products). The following is a description of
     each product line manufactured by the Company.

     AUTOMATED TELLER MACHINE PRODUCTS

     The Company entered the ATM market in October 1992 with the introduction of
     the industry's first cash-dispensing ATM that utilized cost-effective,
     dial-up modem communications, known as AnyCard. Sales of the original
     AnyCard model accounted for approximately 30% of the Company's revenues
     from its introduction until the development of its successor, the AnyCard
     sc (single cassette) model.

     Sales of the single-cassette product commenced in November 1995 and
     comprised the majority of the Company's revenues until June 30, 1997, at
     which time the AnyCard td (tower design) model was introduced. The AnyCard
     td utilized the same electronics and software platform as the AnyCard sc,
     but was housed in a newly designed cabinet that offered both single and
     multiple cassette models. Sales of the AnyCard tds (single cassette) and
     tdm (multiple cassette) models comprised the majority of the Company's
     revenues from their introduction through September 30, 1998.

     In October 1998, the Company introduced its new Ignition Series products
     consisting of the IS-1000, a single cassette model, and the IS-6000, a
     multiple cassette model. These products now comprise all of the Company's
     ATM sales, as inventories of all other ATM products were liquidated in the
     year ended September 30, 1999, and the Company does not intend to produce
     any of the predecessor products in the future. During the year ended
     September 30, 1999, the Company had sales of ATM products to two major
     customers that accounted for more than 10% of sales in the amounts of
     $18,554,624 and $4,781,236, respectfully.


                                       1
<PAGE>   4
     During the year ended September 30, 1999, the Company introduced a new
     product, the Chameleon, which is a web-enabled, interactive, multimedia
     kiosk that provides users with e-commerce and point-of-sale functionality
     in addition to traditional ATM features. Sales of this product in
     commercial quantities will commence in fiscal 2000, and the development of
     application software and additional features will be ongoing.

     TIMED ACCESS CASH CONTROLLER PRODUCTS

     The Company's original product is its electronic cash controller known as
     TACC, which acts as both a drop safe and a cash dispenser. This product
     serves as a depository for cash which is stored in plastic tubes that can
     be retrieved at preprogrammed intervals. The TACC products have been
     instrumental in the reduction of losses due to crime in many segments of
     the retail industry, including convenience stores, retail gasoline,
     specialty retailers, hospitality and entertainment.

     Management believes its TACC products are highly regarded in the retail
     market and have become standard equipment in virtually all new construction
     by major convenience store operators and gasoline retailers. TACC products
     are in use in all 7-Eleven stores, as well as in more than 100,000 other
     locations in the United States and 30 other countries. Current models allow
     for a computer interface which can be used in conjunction with lottery and
     point-of-sale systems.

     Sales of TACC products comprised 14% of the Company's revenues for the year
     ended September 30, 1999.

     ENVIRONMENTAL MONITORING SYSTEM PRODUCTS

     The Company's EMS products are designed to provide leak detection and fuel
     management of underground petroleum storage tanks and their associated
     piping systems to petroleum retailers and other owners and operators of
     underground storage tanks. The EMS can print reports of requested data,
     verify fuel inventories, provide instant notification of alarm conditions
     such as leaks and monitor up to eight storage tanks simultaneously,
     providing a cost efficient method of monitoring fuel inventories. In
     addition, the EMS console has communication ports for interface with
     point-of-sale terminals, modems and computers.

     Sales of EMS products were less than 2% of total revenues in fiscal 1999,
     and management has terminated marketing of EMS products to shift focus to
     the ATM and TACC products. However, the Company will continue to supply
     parts to existing EMS customers on a very limited basis.

                            RESEARCH AND DEVELOPMENT

     To protect against product obsolescence by reason of emerging technologies
     and ensure development of the most advanced products possible, the Company
     has a continuing program of research and development. Management believes
     the Company has established an excellent record of product conception,
     design, development, field testing and commercial production. The research
     and development budget for fiscal 2000 is approximately $3,100,000. Total
     research and development expenditures were approximately $1,700,000,
     $1,400,000 and $1,200,000 for the years ended September 30, 1999, 1998 and
     1997, respectively.


                                       2
<PAGE>   5
                                  MANUFACTURING

     The Company manufactures and assembles its products, produces spare parts,
     and renovates or repairs its products at its facility in Carrollton, Texas.
     The assembly operations consist of configuring components received from
     various vendors with the Company's proprietary hardware and software. Upon
     completion of product assembly, the equipment undergoes functional testing
     and final quality assurance inspection. The Company normally fills and
     ships customer orders within 45 days of receipt, and therefore no
     significant backlog generally exists.

                               SALES AND MARKETING

     The Company markets its ATM and TACC products in the United States through
     Company controlled national accounts and a network of more than 150
     independent distributors and dealers. The distributor network facilitates
     coverage of both large national accounts and diversified end-user groups.

     The Company markets its TACC products overseas through approximately 20
     distributors. The international market lags the U.S. by several years with
     respect to cash management systems. The international market for petroleum
     and convenience stores is heavily influenced by the Company's traditional
     domestic customer base, allowing the Company and its international
     distributors to leverage and develop markets in many diverse geographical
     areas.

     At this time, the Company is distributing automated teller machines in
     Canada and is presently expanding its marketing efforts to include
     additional foreign countries in the future.

                                     SERVICE

     The Company coordinates a national service network of individual service
     dealers to provide electronic and mechanical support for all of its
     products in use. There are approximately 500 such service dealers for ATM
     and TACC products and 60 for EMS products. In addition, the Company has an
     agreement with NCR Corporation to provide comprehensive services, including
     first-line maintenance and field upgrades, to all of the Company's ATM
     customers in the United States.

                             INTELLECTUAL PROPERTIES

     The Company's success depends, in part, on its ability to obtain patents,
     maintain trade secret protection and operate without infringing the
     proprietary rights of others. The Company owns United States patents for
     certain of its products (see "PATENTS AND TRADEMARKS" below) and has filed
     United States and foreign patent applications for other proprietary
     products and expects to continue to file product, process and use patent
     applications with respect to products or improvements developed in the
     future. There can be no assurance, however, that such patent applications
     will be filed or, if filed, that patents will be issued to the Company or,
     if issued, will be adequate to protect its products. In addition, it is not
     possible to predict the degree of protection that patents will afford. It
     is possible that patents issued to or licensed by the Company will be
     successfully challenged, that the Company may unintentionally infringe
     patents of third parties or that the Company may have to alter its products
     or processes or pay licensing fees or cease certain activities to take into
     account patent rights of third parties, thereby causing additional
     unexpected costs and delays which may have a material adverse effect on the
     Company's business.


                                       3
<PAGE>   6
     In addition, competitors may obtain additional patents and proprietary
     rights relating to products or processes used in, necessary to, competitive
     with or otherwise related to those availed of by the Company. The scope and
     validity of these patents and proprietary rights, the extent to which the
     Company may be required to obtain licenses under these patents or under
     other proprietary rights and the cost and availability of licenses are
     unknown, but these factors may limit the Company's ability to market its
     existing or future products. See "LICENSES" below.

     The Company also relies upon unpatented trade secrets and no assurance can
     be given that others will not independently develop substantially
     equivalent proprietary information and techniques or otherwise gain access
     to the Company's trade secrets or disclose such technology or that the
     Company can meaningfully protect its rights to its unpatented trade
     secrets.

                             PATENTS AND TRADEMARKS

     The Company owns two patents relating to each of its ATM products, TACC
     products and EMS products. The Company also owns the registered trademarks
     "AnyCard", "TACC", "Tidel Systems" and "TS and Design".

                                    LICENSES

     The Company grants various distributors a non-exclusive right and license,
     with the right to grant sublicenses, to use the names "Tidel" and "Tidel
     AnyCard", together with any associated trademarks, logos or insignias, for
     the limited purpose of marketing, selling and distributing the Company's
     products.

                            GOVERNMENTAL REGULATIONS

     The Company's EMS unit is produced and sold to provide total compliance and
     documentation to the Environmental Protection Agency ("EPA") and other
     regulatory agencies to ensure customers' compliance with all applicable
     regulations relating to the detection and prevention of petroleum leaks in
     tanks and piping systems. The potential liability from a leaking
     underground storage tank is the primary motivating factor influencing the
     decision to install a leak detection device. The EPA and other federal
     agencies are responsible for the regulation and enforcement of petroleum
     storage and piping systems and the potential leaks therefrom.

     The Company's EMS systems are subject to numerous other state and local
     regulations relating to the storage and dispensing of petroleum products.

                                   COMPETITION

     Competition in the automated teller machine manufacturing business is
     substantial with Diebold, Incorporated and NCR Corporation dominating the
     marketplace. Direct competition to the Company in the off-premises
     automated teller machine market consists of other companies such as Triton
     Systems, Inc., Fujitsu Corporation, Cross Technologies, Inc. and
     Siemens-Nixdorf. Management believes that the quality and value offered by
     its ATM product line allow it to compete effectively in the off-premise
     market.

     Direct competition to the Company in the domestic cash controller market
     comes principally from NKL Industries, McGunn Safe Company, Armor Safe
     Company and AutoVend.


                                       4
<PAGE>   7
                                    EMPLOYEES

     The Company employed 144 and 122 persons at September 30, 1999 and 1998,
     respectively. None of the Company's employees are subject to collective
     bargaining agreements. The Company has not experienced any strikes or work
     stoppages and considers its relationships with its employees to be
     satisfactory.

ITEM 2.  PROPERTIES

     The Company's principal executive offices are located in approximately
     4,100 square feet at 5847 San Felipe, Suite 900, Houston, Texas 77057.

     The Company's subsidiaries occupy approximately 65,000 square feet of space
     in a one story building in Carrollton, Texas, under a lease expiring in
     January 2005. The facility houses the principal administrative offices and
     all manufacturing, testing, product design and research and development
     operations. The subsidiaries also lease approximately 10,000 square feet of
     warehouse space in Carrollton, Texas, under a month-to-month lease.

     At September 30, 1999, the Company owned tangible property and equipment
     costing approximately $3,912,000. Such amount is comprised primarily of
     manufacturing tools, manual and robotic welding equipment, computer
     equipment and systems, and vehicles used in servicing and delivery
     functions.

ITEM 3.  LEGAL PROCEEDINGS

     The Company and its subsidiaries are each subject to certain litigation and
     claims arising in the ordinary course of business. In the opinion of the
     management of the Company, the amounts ultimately payable, if any, as a
     result of such litigation and claims will not have a materially adverse
     effect on the Company's financial position.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     At the Annual Meeting of Stockholders held on July 22, 1999, in Dallas,
     Texas, the following proposals were adopted by the margins indicated:

     a) Election of Directors to hold office until the next annual meeting of
        stockholders and until their successors are elected and qualified.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

                              RESULTS OF OPERATIONS

     OVERVIEW

     The Company's revenues were $45,873,000 for the year ended September 30,
     1999, representing an increase of $12,265,000, or 36%, from fiscal 1998 and
     $15,720,000, or 52%, from fiscal 1997. Operating income for the year was
     $5,117,000 as compared to $4,325,000 in fiscal 1998 and $2,590,000 in
     fiscal 1997. Net income for the periods was not comparable inasmuch as
     fiscal 1997 had no income tax, fiscal 1998 included a tax benefit of
     $307,000, and fiscal 1999 included an income tax expense of $1,800,000.


                                       7
<PAGE>   10
     The significant sales growth was due to the continued strong demand for the
     Company's ATM products. The gross profit from these sales, offset somewhat
     by increased operating expenses, provided the overall improvement in
     operating income.

     A breakdown of net sales by individual product line is provided in the
     following table:

</TABLE>

     ATM sales have significantly increased in the past year due to broad
     customer acceptance of the new Ignition Series and the addition of new
     distributors to the Company's customer base.

     TACC sales have increased gradually during the three-year period as sales
     efforts in domestic markets have intensified.

     All marketing activities for EMS products have terminated, and the Company
     is phasing out of this segment of business.

     Parts, service and other revenues vary directly with sales of finished
     goods, and have increased accordingly.

     GROSS PROFIT, OPERATING EXPENSES AND NON-OPERATING ITEMS

     Gross profit on product sales increased $2,780,000 and $4,265,000 from 1998
     and 1997, respectively, to $14,960,000 in 1999. The gross margin in 1999
     was 32.6% of product sales, compared to 36.2% in 1998 and 35.5% in 1997.
     The decrease in 1999 compared to 1998 resulted from a decline in average
     sales prices for ATM products of $512. In 1998, the average sales prices
     for ATM products decreased $586 from 1997, but gross margin improved
     slightly due to reduced manufacturing overheads from the prior year.


                                       8
<PAGE>   11
     Selling, general and administrative expenses were $9,030,000 in 1999, an
     increase of $1,664,000 from 1998, as a result of higher salaries and
     increased legal expenses. These costs were 19.7% of sales in 1999, a
     decrease from the 1998 and 1997 levels of 21.9% and 25.3%, respectively.
     The percentage decline relates primarily to increased sales volumes.

     Depreciation and amortization was $813,000, $489,000, and $474,000 for the
     years ended September 30, 1999, 1998 and 1997. The increase in 1999
     compared to 1998 and 1997 related to additions of property, plant and
     equipment.

     Interest expense decreased from $473,000 in 1997 to $392,000 in 1998, and
     to $381,000 in 1999 due to the lower cost of borrowings resulting from the
     Company's new revolving credit facility.

     Income tax expense (benefit) in 1998 was attributable to a fourth quarter
     reduction in valuation allowance estimates to reflect the probable
     utilization of the Company's remaining deferred tax assets. This resulted
     in the recognition of a deferred income tax benefit of $947,000 which, when
     offset with current tax expense of $640,000, resulted in a net income tax
     benefit of $307,000. In 1999, the Company recorded a provision for income
     tax expense of $1,800,000, representing an effective tax rate of 38%.

                         LIQUIDITY AND CAPITAL RESOURCES

     The financial position of the Company continues to improve primarily as a
     result of profitable operations and the infusion of capital from the
     exercise of warrants, as reflected in the following key indicators as of
     September 30, 1999, 1998 and 1997:

     The improvement in working capital in 1999 is principally due to net cash
     provided by operating activities of $2,207,022 for the year ended September
     30, 1999.

     In 1999, the Company amended its existing credit agreement with a bank,
     providing for borrowings up to $7,000,000 at the prime rate, with certain
     LIBOR alternatives, until September 30, 2001. Despite a significant
     increase in revenues, the Company's borrowings pursuant to the revolving
     credit agreement were minimal during the year. At September 30, 1999,
     $4,894,634 was outstanding compared to $4,754,604 at September 30, 1998.
     See Note 8 to Notes to Consolidated Financial Statements for a description
     of all outstanding debt and maturities.

     The Company continues to own 698,464 shares of 3CI common stock subsequent
     to its divestiture of a majority interest in February 1994. Although the
     market value of 3CI common stock has recently declined, the Company does
     not believe that such decline represents a permanent impairment of the
     investment. The Company has no immediate plans for the disposal of the
     shares, and accordingly, the shares may be utilized to collateralize
     borrowings. At present, 680,818 shares are pledged to secure an outstanding
     note payable in the principal amount of $480,000.

     The Company's registration statement covering the offering and sale by
     selling shareholders of the common stock underlying all of the Company's
     5,517,500 outstanding warrants was declared effective


                                       9
<PAGE>   12
     on January 29, 1997. As of September 30, 1999, the Company had outstanding
     warrants to purchase 1,425,692 shares of common stock at exercise prices
     ranging from $.50 to $2.19 per share, which expire at various dates through
     July 2002, and if exercised would generate proceeds to the Company of
     approximately $1,400,000.

     The Company's research and development budget for fiscal 2000 has been
     estimated at $3,100,000. The majority of these expenditures are applicable
     to enhancements of the existing product lines, development of new automated
     teller machine products and the development of new technology to facilitate
     the dispensing of products such as postage stamps, money orders, and
     prepaid telephone cards, as well as multiple denominations of currency.
     Total research and development expenditures were approximately $1,700,000,
     $1,400,000, and $1,200,000 for the years ended September 30, 1999, 1998 and
     1997, respectively.

     With its present capital resources, its continuing earnings and cash flow
     from operations, its potential capital from the exercise of warrants, and
     availability of $2,100,000 from its borrowing facility, the Company
     believes it should have sufficient resources to meet its operating needs
     for the foreseeable future and to provide for debt maturities and capital
     expenditures.

     The Company has never paid dividends on shares of its common stock, and
     does not anticipate paying dividends in the foreseeable future. In
     addition, the Company's wholly owned subsidiary is restricted from paying
     dividends to the Company pursuant to the subsidiary's revolving credit
     agreement with a bank.

     SEASONALITY

     The Company can experience seasonal variances in its operations and
     historically has its lowest dollar volume sales months between November and
     February. The Company's operating results for any particular quarter may
     not be indicative of the results for the future quarter or for the year.

     IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

     In June 1998, the FASB issued Statement of Financial Accounting Standards
     No. 133, "Accounting for Derivative Instruments and Hedging Activities"
     ("SFAS 133"). SFAS 133 establishes new accounting and reporting standards
     requiring that all derivative instruments (including certain derivative
     instruments embedded in other contracts) be recorded in the balance sheet
     as either an asset or liability measured at its fair value. SFAS 133
     requires that changes in the derivative's fair value be recognized
     currently in earnings unless specific hedge accounting criteria are met.
     Special accounting for qualifying hedges allows a derivative's gains and
     losses to offset related results on the hedged item in the income statement
     and requires that a company must formally document, designate, and assess
     the effectiveness of transactions that receive hedge accounting. SFAS 133,
     as amended, is effective for all fiscal years beginning after June 15,
     2000. The Company has not yet determined the impact; if any, SFAS 133 will
     have on its financial position or results of operations, and plans to adopt
     this standard during the year ending September 30, 2001.

     THE YEAR 2000 ISSUE

     The Year 2000 Issue is the result of computer programs being written using
     two digits rather than four to define the applicable year. As a result,
     computer programs that have date sensitive software may recognize a date
     using "00" as the year 1900, rather than the year 2000. This could result
     in system


                                       10
<PAGE>   13
     failures or miscalculations causing disruptions in the operations of the
     Company, including, but not limited to, a temporary inability to process or
     transmit data or engage in normal business activities.

     The Company has defined Year 2000 Compliant to mean that a process will
     continue to run in the same manner when dealing with dates on or after
     January 1, 2000, as it did before January 1, 2000. As of January 11, 2000,
     the Company has not encountered any problems as a result of the year 2000
     issue.

     To determine the Company's state of readiness, management conducted an
     evaluation of the Company's computer systems, software and embedded
     technologies to identify those that could be affected by the Year 2000
     Issue. The evaluation, which was focused on the Company's products and most
     critical internal operating functions, revealed that the Company's
     accounting and manufacturing software were the major resources containing
     Year 2000 compliance issues. These resources were repaired during the year
     ended September 30, 1999.

     The Company has determined that there should be no Year 2000 Issues for
     TACC products already sold. The Company has determined that there should be
     no Year 2000 Issues for EMS products sold since June 5, 1991. EMS products
     sold prior to June 5, 1991, were manufactured by a predecessor and have not
     been tested by the Company. In addition, certain EMS 3000 products contain
     hardware manufactured by a third party. This third party component
     equipment has not been tested by the Company. While none of the predecessor
     EMS products or EMS products containing third party component equipment are
     still under warranty by the Company, customer problems, if any, will be
     addressed as incurred.

     The Company has tested the hardware and software platforms for its ATM
     products already sold, excluding the Company's initial AnyCard tube-type
     model ATM. The discontinued tube-type model ATM contains a point-of-sale
     interface manufactured by a third party. In addition, this model is
     dependent on a certain third party host processor for its date and time
     information during a transaction. Neither the point-of-sale interface nor
     the systems of the third party host processor have been tested by the
     Company. The Company believes, however, that there are less than 1,500
     tube-type models still in service and customer problems, if any, will be
     addressed as incurred.

     While the Company has tested the hardware and software platforms for its
     ATM products, these products are dependent on data that is transmitted to
     the product during use. This information is transmitted from financial
     institutions via a system of private and shared computer networks. While
     the federal government has instituted strict Year 2000 compliance
     guidelines and remediation timetables for financial institutions, there can
     be no assurance that the systems of financial institutions, as well as the
     systems of the various private and shared computer networks will be timely
     converted and that the Company's ATM products will be able to conduct
     transactions in a normal manner, if at all.

     Expenditures in fiscal 1999 for the Year 2000 Issue were approximately
     $25,000.

     QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     The Company is exposed to changes in interest rates as a result of
     significant financing through its issuance of variable-rate and fixed-rate
     debt. If market interest rates were to increase 1% in fiscal 2000, there
     would be no material impact on the Company's consolidated results of
     operations or financial position.

                          INDEPENDENT AUDITORS' REPORT


The Board of Directors
Tidel Technologies, Inc.:


         We have audited the consolidated financial statements of Tidel
Technologies, Inc. and subsidiaries as listed in the accompanying index. In
connection with our audits of the consolidated financial statements, we also
have audited the financial statement schedules as listed in the accompanying
index. These consolidated financial statements and financial statement schedules
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these consolidated financial statements and financial
statement schedules based on our audits.

         We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

         In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Tidel
Technologies, Inc. and subsidiaries as of September 30, 1999 and 1998, and the
results of their operations and their cash flows for each of the years in the
three-year period ended September 30, 1999 in conformity with generally accepted
accounting principles. Also in our opinion, the related financial statement
schedules, when considered in relation to the basic consolidated financial
statements taken as a whole, present fairly, in all material respects, the
information set forth therein.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                           SEPTEMBER 30, 1999 AND 1998


(1)      SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

DESCRIPTION OF BUSINESS
Tidel Technologies, Inc. (the "Company") is a Delaware corporation which,
through its wholly owned subsidiaries, develops, manufactures, sells and
supports automated teller machines and related software, electronic cash
security systems, and underground fuel storage monitoring and leak detection
devices primarily in the United States.

PRINCIPLES OF CONSOLIDATION
The consolidated financial statements include the accounts of the Company and
its wholly owned subsidiaries. All significant intercompany items have been
eliminated in consolidation.

RECLASSIFICATIONS
Certain amounts in the prior years' consolidated financial statements have been
reclassified to conform with the current year presentation format.

CASH AND CASH EQUIVALENTS
For purposes of consolidated financial statement presentation and reporting cash
flows, all liquid investments with original maturities at date of purchase of
three months or less are considered cash equivalents.

INVENTORIES
Inventories are stated at the lower of cost or market. Cost is determined using
the standard cost method and includes materials, labor and production overhead
which approximates an average cost method. Reserves are provided to adjust any
slow moving materials or goods to net realizable values.

PROPERTY, PLANT AND EQUIPMENT
Property, plant and equipment are stated at cost. Depreciation is calculated on
the straight-line method over the estimated useful lives of the assets.
Expenditures for major renewals and betterments are capitalized; expenditures
for repairs and maintenance are charged to expense as incurred.

INTANGIBLE ASSETS

All intangible assets are amortized using the straight-line method over a period
ranging from 5 to 10 years, with the exception of goodwill, which is amortized
over 40 years.

IMPAIRMENT OF LONG-LIVED ASSETS
The Company's long-lived assets and certain identifiable intangibles and
goodwill are reviewed for impairment whenever events or changes in circumstances
indicate that the carrying amount of any assets may not be recoverable. In
performing the review for recoverability, the Company estimates the future cash
flows expected to result from the use of the asset and its eventual disposition.
If the sum of the expected future cash flows (undiscounted and without interest
charges) is less than the carrying amount of the asset, an impairment loss is
recognized.

WARRANTIES
Certain products are sold under warranty against defects in materials and
workmanship for a period of one to two years. A provision for estimated warranty
costs is included in accrued liabilities and is charged to operations at the
time of sale.

REVENUE RECOGNITION
Revenues are generally recognized when products are shipped to customers. When
customers, under the terms of specific orders, request that the Company
manufacture and invoice goods on a bill and hold basis, the Company recognizes
revenues based on the completion date required in the order and actual
completion of the manufacturing process.

RESEARCH AND DEVELOPMENT COSTS
Research and development costs are expensed as incurred. Research and
development costs charged to expense approximated $1,700,000, $1,400,000 and
$1,200,000 for the years ended September 30, 1999, 1998 and 1997.

FEDERAL INCOME TAXES
Income taxes are accounted for under the asset and liability method, whereby
deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases. Deferred tax assets and liabilities are measured using enacted tax rates
expected to apply to taxable income in the years in which those temporary
differences are expected to be recovered or settled. The effect on deferred tax
assets and liabilities of a change in tax rates is recognized in determining
income or loss in the period that includes the enactment date.

INVESTMENT SECURITIES
In accordance with Statement of Financial Accounting Standards No. 115,
"Accounting for Certain Investments in Debt and Equity Securities" ("SFAS No.
115"), the Company classifies its investment in 3CI Complete Compliance
Corporation ("3CI") as available for sale, with unrealized gains and losses
excluded from earnings and recorded as a component of other comprehensive
income.

NET INCOME PER SHARE
In accordance with Statement of Financial Accounting Standards No. 128,
"Earnings Per Share" ("SFAS No. 128"), the Company computes and presents both
basic and diluted earnings per share ("EPS") amounts. Basic EPS is computed by
dividing income available to common stockholders by the weighted-average number
of common shares outstanding for the period, and excludes the effect of
potentially dilutive securities (such as options, warrants and convertible
securities) which are convertible into common stock. Dilutive EPS reflects the
potential dilution from options, warrants and convertible securities.

STOCK-BASED COMPENSATION
Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" ("SFAS No. 123"), requires companies to recognize stock-based
expense based on the estimated fair value of employee stock options.
Alternatively, SFAS No. 123 allows companies to retain the current approach set
forth in APB Opinion 25, "Accounting for Stock Issued to Employees", provided
that expanded footnote disclosure is presented. The Company has not adopted the
fair value method of accounting for stock-based compensation under SFAS No. 123,
but has provided the pro forma disclosure required therein.

USE OF ESTIMATES
The preparation of the accompanying consolidated financial statements requires
the use of estimates by management in determining the Company's assets and
liabilities at the date of the consolidated financial statements and the
reported amount of revenues and expenses during the period. Actual results could
differ from these estimates.

FAIR VALUE OF FINANCIAL INSTRUMENTS
Statement of Financial Accounting Standards No. 107, "Disclosures About Fair
Value of Financial Instruments", requires the disclosure of estimated fair
values for financial instruments. Fair value estimates are made at discrete
points in time based on relevant market information. These estimates may be
subjective in nature and involve uncertainties and matters of significant
judgment and therefore, cannot be determined with precision. The Company
believes that the carrying amounts of its financial instruments included in
current assets and current liabilities approximate the fair value of such items
due to their short-term nature. The carrying amount of long-term debt
approximates its fair value because the interest rates approximate market.

(2)      MAJOR CUSTOMERS AND CREDIT RISKS

The Company generally retains a security interest in the underlying equipment
that is sold to customers until it receives payment in full. In addition, one
major customer has pledged additional collateral to the Company. The Company
would incur an accounting loss equal to the carrying value of the accounts
receivable, less any amounts recovered from liquidation of collateral, if a
customer failed to perform according to the terms of the credit arrangements.

During the year ended September 30, 1999, the Company had sales to two major
customers that accounted for more than 10% of sales in the amounts of
$18,554,624 and $4,781,236. During the year ended September 30, 1998, the
Company had such sales to two major customers in the amounts of $3,526,941 and
$3,520,910. During the year ended September 30, 1997, the Company had such sales
to one major customer in the amount of $3,970,227.

Foreign sales accounted for 5%, 4% and 5% of the Company's total sales during
the years ended September 30, 1999, 1998 and 1997, respectively. Foreign sales
are transacted in U.S. dollars.

interest at an annual rate of 10%, and are secured by 500,000 shares of the
Company's common stock issued thereunder. At September 30, 1999, the notes had
an aggregate balance of $382,063 which has been recorded as stock subscriptions

(10)     WARRANTS

The Company's registration statement covering the offering and sale by selling
shareholders of the common stock underlying all of the Company's then
outstanding warrants was declared effective on January 29, 1997. The warrants
related to grants made in connection with debt and equity issues, acquisitions,
directors' remuneration and various services rendered. From the effective date
through September 30, 1999, warrants to purchase 3,550,564 shares have been
exercised generating proceeds to the Company of $3,471,554, net of registration
costs of $109,982, and warrants to purchase 791,244 shares have expired
unexercised. During the year ended September 30, 1999, 207,500 warrants were
exercised generating proceeds of $156,895.

During the year ended September 30, 1999, the Company issued warrants to
purchase 250,000 shares of common stock for directors' remuneration at exercise
prices ranging from $1.25 to $2.19; such prices being equal to the fair market
value of the common stock at the date of the grants. At September 30, 1999, the
Company had outstanding warrants to purchase 1,425,692 shares of common stock
which expire at various dates through July 2002. The warrants have exercise
prices ranging from $0.50 to $2.19 per share and, if exercised, would generate
proceeds to the Company of approximately $1,400,000.

(11)     EMPLOYEE STOCK OPTION PLANS

The Company adopted a Long-Term Incentive Plan in 1997 (the "1997 Plan")
pursuant to which the Company's Board of Directors may grant stock options to
officers and key employees. The 1997 Plan authorizes grants of options to
purchase up to 1,000,000 shares of common stock. Options are granted with an
exercise price equal to the fair market value of the common stock at the date of
grant. Options granted under the 1997 Plan vest over four-year periods and
expire no later than 10 years from the date of grant. At September 30, 1999,
there were 277,500 additional shares available for grant under the 1997 Plan.

The Company's predecessor employee stock option plan, the 1989 Incentive Stock
Option Plan (the "1989 Plan"), was terminated in June 1999. At the date of
termination of the 1989 Plan, there were outstanding options to purchase 438,250
shares of common stock, all of which were outstanding at September 30, 1999.

The weighted-average fair value per share of stock options granted during 1999,
1998 and 1997 was $.78, $1.39 and $1.98, respectively, on the date of grant,
using the Black Scholes model with the following assumptions: risk-free interest
rate of 6.0%, expected life of 4 years, expected volatility of 80.16%, and an
expected dividend yield of 0% for the 1999 granted options; a risk-free interest
rate of 5.62%, expected life of 4 years, expected volatility of 75.66%, and an
expected dividend yield of 0% for the 1998 granted options; and a risk-free
interest rate of 6.49%, expected life of 4 years, expected volatility of
118.05%, and an expected dividend yield of 0% for the 1997 granted options.

The Company applied APB Opinion No. 25 in accounting for its Plans and,
accordingly, no compensation cost has been recognized for its stock options in
the consolidated financial statements. Had the Company determined compensation
cost based on the fair value at the grant date for its stock options under SFAS
No. 123, the Company's net income would have been reduced to the pro forma
amounts indicated as follows:

         THIS CREDIT AGREEMENT (together with all amendments, modifications and

entered into as of 12:01 a.m., April 1, 1999, by and among TIDEL ENGINEERING,
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
the LIBOR Rate in effect for such Interest Period and (ii) Statutory Reserves
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
plus 1/2 of 1%, and (iii) the Base CD Rate in effect for such day plus 1%, and



CREDIT AGREEMENT - Page 1
<PAGE>   10

         (b) the Applicable Margin.

For purposes of this Agreement, any change in the Alternate Base Rate due to a
change in the Prime Rate, Federal Funds Effective Rate or the Three-Month
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.

         Alternate Base Rate Borrowing shall mean as of any date, that portion
of the principal balance of the Revolving Loans bearing interest at the
Alternate Base Rate as of such date.

         Annual Audited Financial Statements shall mean the annual audited
Consolidated and 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 flows for such fiscal year, all setting forth in comparative
form the corresponding figures from the previous fiscal year, all prepared in
conformity with GAAP and accompanied by a report and opinion of independent
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
flows for such fiscal year, all setting forth in comparative form the
corresponding figures from the previous fiscal year, all prepared in conformity
with GAAP by a "Big 6" accounting firm or other accounting firm of similar
national standing and reputation.

and rounded upwards, if necessary, to the next 1/16 of 1%) estimated by the

                  (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
         political subdivisions; or



CREDIT AGREEMENT - Page 28
<PAGE>   37

                           (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.

                  (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

until, but not including, the Term Loan Maturity Date, in a principal amount up
to, but not exceeding the Term Loan Commitment.

         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

all other requisite permits, registrations and consents for that performance
have been obtained for the delivery and performance of the Loan Documents.

         6.4 Other Debt. The Borrower is not in default in the payment of any

Neither the Borrower, nor any Subsidiary thereof, is in default with respect to
any judgment, writ, rule, regulation, order or decree of any Governmental
Authority.

         6.6 Taxes. Except as otherwise permitted pursuant to the terms of

applicable premiums. No accumulated funding deficiency (as defined in Section
302 of ERISA and Section 412 of the Code), whether or not waived, exists with
respect to any Plan. No event has occurred and no condition exists that could
reasonably be expected to constitute grounds for a Plan to be terminated under
circumstances which would cause the Lien provided under Section 4068 of ERISA to
attach to any Property of the Borrower or any ERISA Affiliate. No event has
occurred and no condition exists that could reasonably be expected to cause the
Lien provided under Section 302 of ERISA or Section 412 of the Code to attach to
any Property of the Borrower or any ERISA Affiliate.

not less than the amount that will be required to be paid on or in respect of
the probable liability on the existing debts and other liabilities (including
contingent liabilities) of the Borrower, as they become absolute and mature.

                  (b) The assets of the Borrower do not constitute unreasonably

thereof.

ability to pay such debts as they mature (taking into account the timing and
amounts of cash to be received by the Borrower, and of amounts to be payable on
or in respect of debt of the Borrower). The cash flow of the Borrower, after
taking into account all anticipated uses of the cash of the Borrower, should at
all times be sufficient to pay all such amounts on or in respect of debt of the
Borrower when such amounts are required to be paid.

                  (d) The Borrower does not believe that final judgments against
it in actions for money damages presently pending, if any, will be rendered at a
time when, or in an amount such that, it will be unable to satisfy any such
judgments promptly in accordance with their terms (taking into account the
maximum reasonable amount of such judgments in any such actions and the earliest
reasonable time at which such judgments might be rendered). The cash flow of the
Borrower, after taking into account all other anticipated uses of the cash of
the Borrower (including the payments on or in respect of debt referred to in

all such judgments promptly in accordance with their terms.

rendered by the Borrower; (c) no Eligible Receivable is or shall be subject to
any defense, offset, counterclaim, discount or allowance (as of the time of its
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
shall be legally enforceable in accordance with their terms, subject, as to
enforceability, to the effect of any applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting creators' rights generally;

agreements relating to Eligible Receivables shall be true and correct and in all
respects what they purport to be; (g) to the best of the Borrower's knowledge,
all signatures and endorsements that appear on all documents and agreements

will, upon request from the Lender, execute any instruments and take any steps
required by the Lender in order that all monies due or to become due under any
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.

accordance with Section 7.15(a) above shall at all times thereafter 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

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)
Business Day (or two (2) Business Days in the case of remittances and payments
received after 12:00 noon) and in any event subject to final collection in cash

lockbox(es) (whether in the form of cash, checks, notes, drafts, bills of
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
forth in Section 7.3 hereof, as long as the daily collection procedure
implemented by the provisions of Section 7.15(b) above is in effect, the
Borrower shall furnish to the Lender on each Business Day

for the Borrower and its Subsidiaries for the preceding Business Day prior to
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

or security interest in the Collateral.

hereunder or now or hereafter



CREDIT AGREEMENT - Page 63
<PAGE>   72

existing at law, in equity, or otherwise, and all such remedies, rights and
powers shall be cumulative.

10. Miscellaneous.

         10.1 No Waiver. No waiver of any Default or Event of Default shall be
deemed to be a waiver of any other Default or Event of Default. No failure to
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
thereof, nor shall any single or partial exercise of any such right or power, or
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.

         10.2 Notices. All notices under the Loan Documents shall be in writing
and either (i) delivered against receipt therefor, (ii) mailed by registered or
certified mail, return receipt requested, or (iii) sent by telex, telecopy
(promptly confirmed by mail, except for any notice pursuant to Section
5.1(a)(ii) hereof which need not be confirmed by mail) or telegram, in each case
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
DOCUMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE
STATE OF TEXAS (OTHER THAN THE CONFLICTS OF LAWS PRINCIPLES THEREOF) AND THE
UNITED STATES OF AMERICA.

         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
Borrower and its successors, trustees, receivers and assigns and inure to 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
counterparts, and by the parties hereto on separate counterparts, and each
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,
in connection with (i) the preparation, execution and delivery of this Agreement
(including the exhibits and schedules hereto) and the Loan Documents and the
making of the Loans and the issuance of Letters of Credit hereunder, and (ii)
any modification, supplement or waiver of any of the terms of this Agreement,
the Letters of Credit or any other

Loan Document; (b) all reasonable and documented costs and expenses (including
reasonable and documented attorneys fees) of the Lender in connection with the
enforcement of this Agreement, the Letters of Credit or any other Loan Document;
(c) all transfer, stamp, documentary or other similar taxes, assessments or
charges levied by any governmental or revenue authority in respect of this
Agreement, any Letter of Credit or any other Loan Document or any other document
referred to herein or therein; (d) all costs, expenses, taxes, assessments and
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
FROM ANY (a) ACTUAL OR PROPOSED USE BY THE BORROWER OF THE PROCEEDS OF ANY
EXTENSION OF CREDIT (WHETHER A LOAN OR A LETTER OF CREDIT) BY THE LENDER
HEREUNDER, (b) BREACH BY THE BORROWER OF THIS AGREEMENT OR ANY OTHER LOAN
DOCUMENT, (c) VIOLATION BY THE BORROWER OR ANY OF ITS SUBSIDIARIES OF ANY LAW,
RULE, REGULATION OR ORDER INCLUDING ANY REQUIREMENTS OF ENVIRONMENTAL LAW, (d)
LIENS OR SECURITY INTERESTS GRANTED ON ANY PROPERTY PURSUANT TO OR UNDER THE

FOLLOWING FORECLOSURE UNDER THE LOAN DOCUMENTS, TO THE EXTENT SUCH LOSSES,
LIABILITIES, CLAIMS OR DAMAGES ARISE OUT OF OR RESULT FROM ANY HAZARDOUS
SUBSTANCE, LOCATED IN, ON OR UNDER SUCH PROPERTY PRIOR TO OR AT THE TIME OF SUCH
FORECLOSURE, INCLUDING LOSSES, LIABILITIES, CLAIMS OR DAMAGES WHICH ARE IMPOSED
UPON PERSONS UNDER LAWS RELATING TO OR REGULATING HAZARDOUS SUBSTANCES, SOLELY

PROPERTY BY A COURT OR OTHER REGULATORY OR ADMINISTRATIVE AGENCY OR TRIBUNAL OR
OTHER THIRD PARTY, TO THE EXTENT SUCH LOSSES, LIABILITIES, CLAIMS OR DAMAGES
ARISE OUT OF OR RESULT FROM ANY HAZARDOUS SUBSTANCE, PETROLEUM, PETROLEUM

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

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

                  (d) Notwithstanding anything herein to the contrary, the
Lender may pledge and assign all or any portion of its rights and interests

         10.13 Entire Agreement. This Agreement and the other Loan Documents

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.

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

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

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

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.

                               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.

         FOR VALUE RECEIVED, TIDEL ENGINEERING, L.P., a Delaware limited
partnership (herein called "Borrower"), promises to pay to the order of CHASE
BANK OF TEXAS, N.A., a national banking association (herein called "Payee"), at
2200 Ross Avenue, Dallas, Texas 75201, or at such other place as Payee may
hereafter designate in writing, in immediately available funds and in lawful
money of the United States of America, the principal sum of SEVEN MILLION AND
NO/100 DOLLARS ($7,000,000.00) (or the unpaid balance of all principal advanced
against this note, if that amount is less), together with interest on the unpaid
principal balance of this note from time to time outstanding until maturity at
the rate or rates provided for in the Credit Agreement and interest on all past
due amounts at the Past Due Rate as provided in the Credit Agreement; provided,
that for the full term of this note, the interest rate produced by the aggregate
of all sums paid or agreed to be paid to the holder of this note for the use,
forbearance or detention of the debt evidenced hereby shall not exceed the
Highest Lawful Rate, if any, applicable to Payee.

         If, for any reason whatever, the interest paid or received on this note
during its full term produces a rate which exceeds the Highest Lawful Rate, if
any, applicable to Payee, the holder of this note shall refund to the payor or,
at the holder's option, credit against the principal of this note such portion
of said interest as shall be necessary to cause the interest paid on this note
to produce a rate equal to the Highest Lawful Rate, if any, applicable to payee.
All sums paid or agreed to be paid to the holder of this note for the use,
forbearance or detention of the indebtedness evidenced hereby shall, to the
extent permitted by applicable law, be amortized, prorated, allocated and spread
in equal parts throughout the full term of this note, so that the interest rate
is uniform throughout the full term of this note. 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 1D.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 Article 1D.103 (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 1D of the
Texas Credit Title, whichever that Lender shall elect to substitute for the
"weekly ceiling," and vice versa, each such substitution to have the effect
provided in Chapter 1D of the Texas Credit Title; and 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 1D 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 Section 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 regulate certain revolving credit loan accounts and
revolving tri-party accounts) shall not govern or in any manner apply to the
Obligations.

                         REPRESENTATIONS AND WARRANTIES

     Debtor represents and warrants as follows:

     (a) Debtor is the legal and equitable owner and holder of marketable title
to the Collateral free of any material adverse claim and free of any Lien except
only for the Liens granted hereby and those other Liens (if any) expressly
referred to, described in or permitted by this Agreement or any other Loan
Documents. Except with respect to Liens permitted by this Agreement or by the
terms of the other Loan Documents, Debtor has not heretofore signed any
financing statement or other similar instrument directly or indirectly affecting
the Collateral or any part of it which has not been completely terminated of
record, and no such financing statement or other similar instrument signed by
Debtor is now on file in any public office.

     (b) As of the date of this Agreement, the location of Debtor is the address
set forth at the beginning of this Agreement and in this regard, Debtor's
location is defined to mean (i) Debtor's place of business if Debtor has only
one such place of business; or (ii) Debtor's chief executive office if Debtor
has more than one place of business. As of the date of this Agreement, the
primary books and records of Debtor with regard to the Collateral are maintained
and kept at such address of Debtor set forth at the beginning of this Agreement.

     (c) No part of the Collateral consists or will consist of consumer goods,
farm products or timber and the like or accounts resulting from the sale
thereof.

     (d) Debtor has the right to use, assign and pledge, without payment of any
amounts to any third parties (other than normal licensing fees payable to
licensors of prefabricated software programs currently utilized by Debtor, if
any), any and all accounting, monitoring, billing, recordkeeping or other
similar types of systems, together with all related software, currently utilized
by Debtor in its operations. Prior to commencement of any use by Debtor of any
custom designed or similar types of accounting, monitoring, billing,
recordkeeping or other similar types of systems, together with all related
software, Debtor shall cause any and all licensors thereof to consent in writing
to the use by Secured Party of such systems and related software upon payment by
Secured Party to such licensors of the amounts normally due and payable on a
periodic basis by Debtor to such licensors in connection with Debtor's day to
day use and implementation of such systems and related software (the form of
such consents from the applicable licensors to be upon terms and conditions
reasonably acceptable to Secured Party).

     (e) As of the date of this Agreement, Debtor has not ever changed its name
whether by amendment of its organizational documents or otherwise, except as
disclosed in the Organizational Documents of Debtor delivered to Secured Party
in connection with the execution and delivery of the Credit Agreement and all
other Loan Documents.

     (f) The Collateral is free from damage caused by fire or other casualty.

     (g) None of the products manufactured and sold, nor any processes or
know-how used by Debtor, presently infringe or are alleged to infringe, in any
material respect, any patent, trade secret, trademark, service mark, tradename,
copyright or other proprietary right of any other Person.

     (h) Except for Liens expressly permitted by this Agreement or any of the
other Loan Documents, the Liens of this Agreement will constitute valid and
perfected first and prior Liens on the Collateral when a financing statement
covering the Collateral is duly filed for record in the offices of the Secretary
of State of the State of Texas.

     (i) As of the date hereof, other than Inventory of Debtor which is in
transit, all of the Inventory and Equipment of Debtor is located at the
locations described on Schedule 1 attached hereto.

                                    ARTICLE 4
                                    COVENANTS

     4.1 Debtor covenants and agrees with Secured Party as follows:

          (a) Debtor shall furnish to Secured Party such instruments as may be
required by Secured Party to assure the transferability of any Collateral when
and as often as may be reasonably requested by Secured Party.

          (b) If the validity or priority of this Agreement or of any material
rights, titles, security interests or other interests created or evidenced
hereby shall be attacked, endangered or questioned or if any legal proceedings
are instituted with respect thereto, Debtor will give prompt written notice
thereof to Secured Party and at Debtor's own cost and expense will diligently
endeavor to cure any defect that may be developed or claimed, and will take all
necessary and proper steps for the defense of such legal proceedings, and
Secured Party (whether or not named as a party to legal proceedings with respect
thereto) is hereby authorized and empowered to take such additional steps as in
its reasonable judgment and discretion may be necessary or proper for the
defense of any such legal proceedings or the protection of the validity or
priority of this Agreement and the rights, titles, security interests and other
interests created or evidenced hereby, and all expenses so incurred of every
kind and character shall constitute sums advanced pursuant to Section 4.2 of
this Agreement.

          (c) Notwithstanding the security interest in proceeds granted herein,
Debtor will not, except as otherwise expressly permitted herein or in the other
Loan Documents, sell, lease, exchange, lend, rent, assign, license, transfer or
otherwise dispose of, or pledge, hypothecate or grant any Lien in, or permit to
exist any Lien against, all or any part of the Collateral or any interest
therein or permit any of the foregoing to occur or arise or permit title to the
Collateral, or any interest therein, to be vested in any other party, in any
manner whatsoever, by operation of law or otherwise, without the prior written
consent of Secured Party. Except as


SECURITY AGREEMENT (PERSONAL PROPERTY) - Page 5
<PAGE>   6
provided by the Loan Documents or as otherwise permitted herein, Debtor shall
not, without the prior written consent of Secured Party, (i) acquire any such
Collateral under any arrangement whereby the seller or any other person retains
or acquires any security interest in such Collateral or (ii) return or give
possession of any such Collateral to any supplier or any other Person except in
the ordinary course of business. Subject to the exercise of Secured Party's
rights and remedies granted herein or in any other Loan Document, Debtor may use
the Collateral in any lawful manner not inconsistent with this Agreement or the
other Loan Documents or with the terms or conditions of any policy of insurance
thereon and may also sell or lease such Collateral in the ordinary course of
business except as otherwise provided under the other Loan Documents. A sale in
the ordinary course of business does not include a transfer in partial or total
satisfaction of a debt. Subject to the exercise of Secured Party's rights and
remedies granted herein or in any other Loan Document, Debtor may also use and
consume any raw materials or supplies, the use and consumption of which are
necessary to carry on the business of Debtor.

          (d) If any portion of the Collateral is now or hereafter evidenced by
any promissory notes, trade acceptances or other instruments for the payment of
money having an original principal or face amount in excess of $10,000, Debtor
will immediately deliver them to Secured Party, appropriately endorsed to
Secured Party's order. Regardless of the form of endorsement, Debtor waives
presentment, demand, notice of dishonor, protest and notice of protest. After an
Event of Default which is continuing, but prior to such delivery, such
Collateral shall be held in trust for the benefit of Secured Party and subject
to the Liens granted herein.

          (e) Debtor shall maintain property and liability insurance policies
covering the Collateral and claims related to the Collateral ("Collateral
Insurance") in accordance with the requirements of Section 6.7 of the Credit
Agreement. Debtor shall deliver certificates evidencing renewal of the
Collateral Insurance before termination of any insurance policies representing
Collateral Insurance. Upon request, Debtor shall deliver certificates evidencing
the Collateral Insurance and copies of the underlying policies as they are
available. Promptly upon obtaining knowledge thereof, Debtor shall notice
Secured Party of any casualty to the Collateral which exceeds $100,000
("Material Casualty"). At the request of Secured Party, Debtor shall pursue
claims for payment related to the Material Casualty.

          (f) Upon the receipt by Secured Party or Debtor of any insurance
proceeds from insurance policies required to be maintained pursuant to Section
6.7 of the Credit Agreement on account of (1) each separate loss, damage or
injury to any Collateral in excess of $100,000 if no Default or Event of Default
shall have occurred which is continuing or (2) any separate loss, damage or
injury to any Collateral (regardless of the amount of loss, damage or injury) if
a Default or Event of Default shall have occurred which is continuing, such
insurance proceeds shall be promptly delivered and turned over to Secured Party
(if the same have not been previously received by Secured Party), and except as
otherwise specified below, such insurance proceeds shall be promptly applied by
Secured Party in payment of the Debt (such order and manner of application to he
at the discretion of Secured Party). With respect to such net insurance
proceeds, Debtor may elect, by written notice delivered to Secured Party, not
later than the tenth day after receipt of such net proceeds by Secured Party or
Debtor, to utilize and apply all or a portion of such net proceeds for the
purpose of replacing, repairing or restoring the


SECURITY AGREEMENT (PERSONAL PROPERTY) - Page 6
<PAGE>   7


     relevant Collateral, and in such event, any required application of such
     net proceeds against the Debt in accordance with the preceding sentence
     shall be reduced dollar for dollar by the amount of such election by
     Debtor. Such an election by Debtor shall not be effective, however, unless
     (1) at the time of such election no Default or Event of Default shall have
     occurred which is continuing, (2) Debtor shall have certified to Secured
     Party that the net proceeds of the insurance adjustment for such loss,
     damage or injury to Collateral, together with other funds available to
     Debtor, shall be sufficient to complete such contemplated replacement,
     repair or restoration in accordance with all applicable laws, regulations
     and ordinances, and (3) if the amount of the net proceeds in question
     exceeds $100,000, Debtor shall have obtained the written consent of the
     Secured Party to such use and application of such insurance proceeds.

               (g) In the event of a valid election by Debtor under Section
     4.1(f) above to utilize all or a portion of such insurance proceeds to
     replace, repair or restore the relevant Collateral, upon the request of
     Secured Party, Debtor shall place into an account under Secured Party's
     control (the "Insurance Proceeds Account") the amount of net insurance
     proceeds to be utilized for such contemplated replacement, repair or
     restoration, pursuant to agreements in form, scope and substance reasonably
     satisfactory to Secured Party (including a pledge of such Insurance
     Proceeds Account as additional security for the Debt). The Insurance
     Proceeds Account, including all earnings thereon, if any, shall be
     available to Debtor solely for the replacement, repair or restoration of
     the Collateral suffering the applicable injury, loss or damage; provided,
     however, that at any time that a Default or Event of Default shall occur
     and be continuing, the balance of the Insurance Proceeds Account, together
     with all earnings thereon, may be immediately applied by Secured Party to
     repay the Debt in such order as Secured Party shall elect in its
     discretion. Secured Party shall be entitled to require proof, as a
     condition to Debtor making of any withdrawal from the Insurance Proceeds
     Account, that the amount of such withdrawal is being applied for the
     purposes permitted hereunder. Additionally, any proceeds of the Insurance
     Proceeds Account may be made available and advanced by Secured Party
     directly to Debtor, or directly to suppliers, manufacturers, contractors
     and other persons entitled to payment in accordance with and subject to
     reasonable conditions to disbursements as Secured Party may impose to
     assure that such replacement, repair or restoration of the relevant
     Collateral is paid for and performed and that no Liens arise by reason
     thereof.

               (h) No Inventory nor Equipment shall be located at any location,
     other than the locations set forth on Schedule 1 attached hereto, which has
     not been disclosed in writing to Secured Party in advance of such Inventory
     or Equipment being located at such location and for which Financing
     Statements, and landlord subordinations or warehousemens' agreements, as
     the case may be, (if such locations are not owned by Debtor) covering such
     portion of the Inventory or Equipment, as the case may be, have not been
     executed and delivered by Debtor and filed for record with the appropriate
     Governmental Authority necessary to perfect the Liens granted hereby.

               (i) Debtor agrees to defend the Collateral and its proceeds
     against all claims and demands of any Person at any time claiming the
     Collateral.

          4.2 If Debtor fails to comply with any of its agreements, covenants or
     obligations under this Agreement or any other Loan Document, after giving
     effect to any applicable cure


     SECURITY AGREEMENT (PERSONAL PROPERTY) - Page 7
<PAGE>   8
period, Secured Party (in Debtor's name or in Secured Party's own name) may
perform them or cause them to be performed for the account and at the expense of
Debtor, but shall have no obligation to perform any of them or cause them to be
performed. Any and all expenses thus incurred or paid by Secured Party shall be
Debtor's obligations to Secured Party due and payable on demand, or if no demand
is sooner made, then they shall be due on or before four (4) years after the
respective dates on which they were incurred, and each shall bear interest from
the date one (1) Business Day after Secured Party demands payment for such
amounts until the date Debtor repays such amounts to Secured Party, at the Past
Due Rate. Upon making any such payment or incurring any such expense, Secured
Party shall be fully and automatically subrogated to all of the rights of the
person, corporation or body politic receiving such payment. Any amounts owing by
Debtor to Secured Party pursuant to this or any other provision of this
Agreement shall automatically and without notice be and become a part of the
Debt and shall be secured by this and all other instruments securing the Debt.
The amount and nature of any such expense and the time when it was paid shall be
fully established by the affidavit of Secured Party or any of Secured Party's
officers or agents. The exercise of the privileges granted to Secured Party in
this Section shall in no event be considered or constitute a cure of the default
or a waiver of Secured Party's right at any time after an Event of Default to
declare the Debt to be at once due and payable, but is cumulative of such right
and of all other rights given by this Agreement, the Credit Agreement, the Notes
and the Loan Documents and of all rights given Secured Party by law.

                                    ARTICLE 5
                     ASSIGNMENT OF PAYMENTS; CERTAIN POWERS
                         OF SECURED PARTY; NO ASSUMPTION

          5.1 Upon the occurrence of an Event of Default and so long as it is
continuing and has not been expressly waived by Secured Party in writing,
Secured Party may request Debtor to notify each account debtor and each other
Person (each a "Collateral Obligor") obligated to make payment in respect of any
of the Collateral of the Liens in such Collateral granted herein and instruct
such Collateral Obligor to pay over to Secured Party, all or any part of the
Collateral without making any inquiries as to the status or balance of Debtor
and without any notice to or further consent of Debtor. If Debtor does not
promptly comply with such request, Secured Party may, but shall not be obligated
to, directly notify each such Collateral Obligor of the Liens in the Collateral
granted herein and instruct such Collateral Obligor to pay over to Secured
Party, all or any part of the Collateral without making any inquiries as to the
status or balance of Debtor and without any notice to or further consent of
Debtor.

          5.2 The powers conferred on Secured Party pursuant to this Article 5
are conferred solely to protect Secured Party's interest in the Collateral and
shall not impose any duty or obligation on Secured Party to perform any of the
powers herein conferred. Additionally, the powers conferred on Secured Party
pursuant to this Article 5 are cumulative of all other similar, related or
additional powers conferred on Secured Party by the terms and provisions of
Section 9.21 of the Credit Agreement and are not intended to limit or restrict
in any manner whatsoever any of such powers and rights conferred on Secured
Party under the terms and provisions of the Credit Agreement or any other Loan
Documents. No exercise of any of such rights provided for in this Article 5 or
in the Credit Agreement shall constitute a retention of


SECURITY AGREEMENT (PERSONAL PROPERTY) - Page 8
<PAGE>   9
collateral in satisfaction of the indebtedness as provided for in Section 9.505
of the Uniform Commercial Code of Texas or the state or states where the
applicable Collateral is located.

                                    ARTICLE 6
                                EVENTS OF DEFAULT

     An Event of Default under the Credit Agreement shall constitute an Event of
Default (herein so called) under this Agreement.

                                    ARTICLE 7
                          REMEDIES IN EVENT OF DEFAULT

     7.1 In addition to the other rights and remedies provided for in the Credit
Agreement, upon the occurrence and during the continuation of an Event of
Default:

               (a) Secured Party is authorized, in any legal manner and without
breach of the peace, to take possession of the Collateral (DEBTOR HEREBY WAIVES
ALL CLAIMS FOR DAMAGES ARISING FROM OR CONNECTED WITH ANY SUCH TAKING, EXCEPT AS
MAY BE CAUSED BY THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SECURED PARTY)
and of all books, records and accounts relating thereto and to exercise without
interference from Debtor any and all rights which Debtor has with respect to the
management, possession, operation, protection, preservation, distribution or
resale of the Collateral, including the right to sell or rent the same for the
account of Debtor and to deduct from such sale proceeds or such rents all costs,
expenses and liabilities of every character incurred by Secured Party in
collecting such sale proceeds or such rents, and in managing, operating,
maintaining, protecting or preserving the Collateral and to apply the remainder
of such sales proceeds or such rents on the Debt in such manner as Secured Party
may elect. Before any sale, Secured Party may, at its option, complete the
processing of any of the Collateral and/or repair or recondition the same to
such extent as Secured Party may deem advisable and any reasonable sums expended
therefor by Secured Party shall be reimbursed by Debtor. Secured Party may take
possession of Debtor's premises to complete such processing, repairing and/or
reconditioning, using the facilities and other property of Debtor to do so, to
store any Collateral and to conduct any sale as provided for herein, all without
compensation to Debtor. All costs, expenses, and liabilities incurred by Secured
Party in collecting such sales proceeds or such rents, or in managing,
operating, maintaining, protecting or preserving such properties, or in
processing, repairing and/or reconditioning the Collateral if not paid out of
such sales proceeds or such rents as hereinabove provided, shall constitute a
demand obligation owing by Debtor and shall bear interest from the date of
expenditure until paid at the Past Due Rate, all of which shall constitute a
portion of the Debt. If necessary to obtain the possession provided for above,
Secured Party may invoke any and all legal remedies to dispossess Debtor,
including specifically one or more actions for forcible entry and detainer. In
connection with any action taken by Secured Party pursuant to this paragraph,
Secured Party shall not be liable for any loss sustained by Debtor resulting
from any failure to sell or let the Collateral, or any part thereof, or from any
other act or omission of Secured Party with respect to the Collateral unless
such loss is caused by the gross negligence or willful misconduct of Secured
Party, nor shall Secured Party be obligated to perform or discharge any
obligation, duty, or liability under any sale or lease


SECURITY AGREEMENT (PERSONAL PROPERTY) - Page 9
<PAGE>   10
agreement covering the Collateral or any part thereof or under or by reason of
this instrument or the exercise of rights or remedies hereunder.

               (b) Secured Party may, without notice except as hereinafter
provided, sell the Collateral or any part thereof at public or private sale
(with or without appraisal or having the Collateral at the place of sale) for
cash, upon credit, or for future delivery, and at such price or prices as
Secured Party may deem best, and Secured Party may be the purchaser of any and
all of the Collateral so sold and may apply upon the purchase price therefor any
of the Debt and thereafter hold the same absolutely free from any right or claim
of whatsoever kind. In any such public or private sale, Secured Party may (but
shall not be obligated to) submit a bid in the form of a credit against the Debt
owed to Secured Party, and Secured Party or its designee may accept title to
property purchased at such public or private sale. Upon any such sale Secured
Party shall have the right to deliver, assign and transfer to the purchaser
thereof the Collateral so sold. Each purchaser at any such sale shall hold the
property sold absolutely free from any claim or right of whatsoever kind,
including any equity or right of redemption, stay or appraisal which Debtor has
or may have under any rule of law or statute now existing or hereafter adopted.
To the extent notice is required by applicable law, Secured Party shall give
Debtor written notice at the address set forth herein (which shall satisfy any
requirement of notice or reasonable notice in any applicable statute) of Secured
Party's intention to make any such public or private sale. Such notice (if any
is required by applicable law) shall be personally delivered or mailed, postage
prepaid, at least ten (10) calendar days before the date fixed for a public
sale, or at least (10) calendar days before the date after which the private
sale or other disposition is to be made, unless the Collateral is of a type
customarily sold on a recognized market, is perishable or threatens to decline
speedily in value. Such notice (if any is required by applicable law), in case
of public sale, shall state the time and place fixed for such sale or, in case
of private sale or other disposition other than a public sale, the time after
which the private sale or other such disposition is to be made. Any public sale
shall be held at such time or times, within the ordinary business hours and at
such place or places, as Secured Party may fix in the notice of such sale. At
any sale, the Collateral may be sold in one lot as an entirety or in separate
parcels as Secured Party may determine. Secured Party shall not be obligated to
make any sale pursuant to any such notice. Secured Party may, without notice or
publication, adjourn any public or private sale or cause the same to be
adjourned from time to time by announcement at any time and place fixed for the
sale, and such sale may be made at any time or place to which the same may be so
adjourned. In case of any sale of all or any part of the Collateral on credit or
for future delivery, the Collateral so sold may be retained by Secured Party
until the selling price is paid by the purchaser thereof, but Secured Party
shall not incur liability in case of the failure of such purchaser to take up
and pay for the Collateral so sold, and in case of any such failure, such
Collateral may again be sold upon like notice. Each and every method of
disposition described in this Section shall constitute disposition in a
commercially reasonable manner. Each Obligor, to the extent applicable, shall
remain liable for any deficiency.

               (c) Secured Party shall have all the rights of a secured party
after default under the Uniform Commercial Code of the state or states where the
applicable Collateral is situated, and in conjunction with, in addition to or in
substitution for those rights and remedies:


SECURITY AGREEMENT (PERSONAL PROPERTY) - Page 10
<PAGE>   11


               (i) Secured Party may require Debtor to assemble the Collateral
     and make it available at a place Secured Party designates which is mutually
     convenient to allow Secured Party to take possession or dispose of the
     Collateral; and

               (ii) it shall not be necessary that Secured Party take possession
     of the Collateral or any part thereof before the time that any sale
     pursuant to the provisions of this Article is conducted and it shall not be
     necessary that the Collateral or any part thereof be present at the
     location of such sale; and

               (iii) before application of proceeds of disposition of the
     Collateral to the Debt, such proceeds shall be applied to the reasonable
     expenses of retaking, holding, preparing for sale or lease, selling,
     leasing, licensing, sublicensing and the like, as well as reasonable
     attorneys' fees and legal expenses incurred by Secured Party, each Obligor,
     to the extent applicable, to remain liable for any deficiency; and

               (iv) the sale by Secured Party of less than the whole of the
     Collateral shall not exhaust the rights of Secured Party hereunder, and
     Secured Party is specifically empowered to make successive sale or sales
     hereunder until the whole of the Collateral shall be sold; and, if the
     proceeds of such sale of less than the whole of the Collateral shall be
     less than the aggregate of the Debt, this Agreement and the security
     interest created hereby shall remain in full force and effect as to the
     unsold portion of the Collateral just as though no sale had been made; and

               (v) in the event any sale hereunder is not completed or is
     defective in the reasonable opinion of Secured Party, such sale shall not
     exhaust the rights of Secured Party hereunder and Secured Party shall have
     the right to cause a subsequent sale or sales to be made hereunder; and

               (vi) any and all statements of fact made in any bill of sale or
     assignment or other instrument evidencing any foreclosure sale hereunder
     shall be taken as rebuttable evidence of the truth of the facts so stated;
     and

               (vii) Secured Party may appoint or delegate any one or more
     persons as agent to perform any act or acts necessary or incident to any
     sale held by Secured Party, including the sending of notices and the
     conduct of sale, but in the name and on behalf of Secured Party; and

               (viii) demand of performance, advertisement and presence of
     property at sale are hereby WAIVED and Secured Party is hereby authorized
     to sell hereunder any evidence of debt it may hold as security for the
     Debt. Except as provided herein or in any other Loan Document, all demands
     and presentments of any kind or nature are expressly WAIVED by Debtor.
     Debtor WAIVES the right to require Secured Party to pursue any other remedy
     for the benefit of Debtor and agrees that Secured Party may proceed against
     any Obligor for the amount of the Debt owed to Secured Party without taking
     any action against any other Obligor or any other person or entity and
     without



SECURITY AGREEMENT (PERSONAL PROPERTY) - Page 11
<PAGE>   12

selling or otherwise proceeding against or applying any of the Collateral in
Secured Party's possession.

          (d) Secured Party may apply to a court of competent jurisdiction for
the appointment of a receiver, or a receiver and manager, over Debtor, or any or
all of the Collateral, with such duties, powers and obligations as the court
making such appointment shall confirm, and Debtor hereby irrevocably consents to
the appointment of such receiver or such receiver and manager.

     7.2 All remedies expressly provided for in the Agreement are cumulative of
any and all other remedies existing at law or in equity and are cumulative of
any and all other remedies provided for in any other instrument securing the
payment of the Debt, or any part thereof, or otherwise benefiting Secured Party,
and the resort to any remedy provided for hereunder or under any such other
instrument or provided for by law shall not prevent the concurrent or subsequent
employment of any other appropriate remedy or remedies.

     7.3 Secured Party may resort to any security given by this Agreement or to
any other security now existing or hereafter given to secure the payment of the
Debt, in whole or in part, and in such portions and in such order as may seem
best to Secured Party in its sole and uncontrolled discretion, and any such
action shall not in anywise be considered as a waiver of any of the rights,
benefits or security interests evidenced by this Agreement.

     7.4 To the full extent Debtor may do so, Debtor agrees that Debtor will not
at any time insist upon, plead, claim or take the benefit or advantage of any
law now or hereafter in force providing for any appraisement, valuation, stay,
extension or redemption, and Debtor, for Debtor, Debtor's successors, receivers,
trustees and assigns, and for any and all persons ever claiming any interest in
the Collateral, to the extent permitted by law, hereby WAIVE and release all
rights of redemption, valuation, appraisement, stay of execution, notice of
intention to mature or to declare due the whole of the Debt, notice of election
to mature or to declare due the whole of the Debt and all rights to a marshaling
of the assets of Debtor, including the Collateral, or to a sale in inverse order
of alienation in the event of foreclosure of the security interest hereby
created.

                                    ARTICLE 8
                              ADDITIONAL AGREEMENTS

     8.1 Subject to the automatic reinstatement provisions of Section 8.21
below, upon full satisfaction of the Debt, complete performance of all of the
obligations of the Obligors under the Loan Documents and final termination of
Secured Party's obligations, if any, to make any further advances under any Note
or to provide any other financial accommodations to any Obligor, all rights
under this Agreement shall terminate and the Collateral shall become wholly
clear of the security interest evidenced hereby, and upon written request by
Debtor such security interest shall be released by Secured Party in due form and
at Debtor's cost.

     8.2 Secured Party may waive any default without waiving any other prior or
subsequent default. Secured Party may remedy any default without waiving the
default


SECURITY AGREEMENT (PERSONAL PROPERTY) - Page 12

remedied. The failure by Secured Party to exercise any right, power or remedy
upon any default shall not be construed as a waiver of such default or as a
waiver of the right to exercise any such right, power or remedy at a later date.
No single or partial exercise by Secured Party of any right, power or remedy
hereunder shall exhaust the same or shall preclude any other or further exercise
thereof, and every such right, power or remedy hereunder may be exercised at any
time and from time to time. No modification or waiver of any provision hereof
nor consent to any departure by Debtor therefrom shall in any event be effective
unless the same shall be in writing and signed by Secured Party, and then such
waiver or consent shall be effective only in the specific instances, for the
purpose for which given and to the extent therein specified. No notice to nor
demand on Debtor in any case shall of itself entitle Debtor to any other or
further notice or demand in similar or other circumstances. Acceptance by
Secured Party of any payment in an amount less than the amount then due on the
Debt shall be deemed an acceptance on account only and shall not in any way
affect the existence of a default hereunder.

     8.3 Subject to Section 9.11 of the Credit Agreement, Secured Party may at
any time and from time to time in writing (a) waive compliance by Debtor with
any covenant herein made by Debtor to the extent and in the manner specified in
such writing; (b) consent to Debtor's doing any act which hereunder Debtor is
prohibited from doing, or consent to Debtor's failing to do any act which
hereunder Debtor is required to do, to the extent and in the manner specified in
such writing; (c) release any part of the Collateral, or any interest therein,
from the security interest of this Agreement; or (d) release any Person liable,
either directly or indirectly, for the Debt or for any covenant herein or in any
other instrument now or hereafter securing the payment of the Debt, without
impairing or releasing the liability of any other Person. No such act shall in
any way impair the rights of Secured Party hereunder except to the extent
specifically agreed to by Secured Party in such writing.

     8.4 Secured Party shall not be required to take any steps necessary to
preserve any rights against prior parties to any of the Collateral.

     8.5 The Liens and other rights of Secured Party hereunder shall not be
impaired by any indulgence, moratorium or release granted by Secured Party,
including but not limited to (a) any renewal, extension or modification which
Secured Party may grant with respect to the Debt; (b) any surrender compromise,
release, renewal, extension, exchange or substitution which Secured Party may
grant in respect of any item of the Collateral, or any part thereof or any
interest therein; or (c) any release or indulgence granted to any endorser,
guarantor or surety of the Debt.

     8.6 A carbon, photographic or other reproduction of this Agreement or of
any financing statement relating to this Agreement shall be sufficient as a
financing statement. Debtor will cause all financing statements and continuation
statements relating hereto to be recorded, filed, re-recorded and refiled in
such manner and in such places as Secured Party shall reasonably request and
will pay all such recording, filing, re-recording, and refiling taxes, fees and
other charges.

     8.7 This Agreement may be executed in several identical counterparts and by
the parties hereto on separate counterparts, and each counterpart, when so
executed and delivered,


SECURITY AGREEMENT (PERSONAL PROPERTY) - Page 13
<PAGE>   14
shall constitute an original instrument, and all such separate counterparts
shall constitute but one and the same instrument.

     8.8 In the event the ownership of the Collateral or any part thereof
becomes vested in a Person other than Debtor, Secured Party may, without notice
to Debtor deal with such successor or successors in interest with reference to
this Agreement and to the Debt in the same manner as with Debtor, without in any
way vitiating or discharging Debtor's liability hereunder or upon the Debt. No
sale of the Collateral, and no forbearance on the part of Secured Party and no
extension of the time for the payment of the Debt given by Secured Party shall
operate to release, discharge, modify, change or affect, in whole or in part,
the liability of Debtor hereunder for the payment of the Debt or the liability
of any other person hereunder for the payment of the Debt, except as agreed to
in writing by Secured Party or as expressly provided in the Credit Agreement.

     8.9 Any other or additional security taken for the payment of any of the
Debt shall not in any manner affect the security given by this Agreement.

     8.10 To the extent that proceeds of the Debt are used to pay indebtedness
secured by any outstanding Lien against the Collateral, such proceeds have been
advanced by Secured Party at Debtor's request, and Secured Party shall be
subrogated to any and all Liens owned by any owner or holder of such outstanding
Lien, irrespective of whether said Lien is released.

     8.11 If any part of the Debt cannot be lawfully secured by this Agreement,
or if the Liens of this Agreement cannot be lawfully enforced to pay any part of
the Debt, then and in either such event, at the option of Secured Party, all
payments on the Debt shall be deemed to have been first applied against that
part of the Debt.

     8.12 Subject to Section 9.11 of the Credit Agreement, this Agreement shall
not be changed orally but shall be changed only by agreement in writing signed
by Debtor and Secured Party. No course of dealing between the parties, no usage
of trade and no parole or extrinsic evidence of any nature shall be used to
supplement or modify any of the terms or provisions of this Agreement.

     8.13 Any notice, request or other communication required or permitted to be
given hereunder shall be given as provided in the Credit Agreement.

     8.14 This Agreement shall be binding upon Debtor, and the trustees,
receivers, successors and assigns of Debtor, including all successors in
interest of Debtor in and to all or any part of the Collateral, and shall
benefit Secured Party and its successors and assigns.

     8.15 If any provision of this Agreement is held to be illegal, invalid or
unenforceable under present or future laws, the legality, validity and
enforceability of the remaining provisions of this Agreement shall not be
affected thereby, and this Agreement shall be liberally construed so as to carry
out the intent of the parties to it. Each waiver in this Agreement is subject to
the overriding and controlling rule that it shall be effective only if and to
the extent that (a) it is not


SECURITY AGREEMENT (PERSONAL PROPERTY) - Page 14
<PAGE>   15


prohibited by applicable law and (b) applicable law neither provides for nor
allows any material sanctions to be imposed against Secured Party for having
bargained for and obtained it.

     8.16 Secured Party shall be deemed to have exercised reasonable care in the
custody and preservation of any of the Collateral in its possession if it takes
such action for that purpose as Debtor requests in writing, but failure of
Secured Party to comply with such request shall not of itself be deemed a
failure to have exercised reasonable care, and no failure of Secured Party to
take any action so requested by Debtor shall be deemed a failure to exercise
reasonable care in the custody or preservation of such Collateral. Secured Party
shall not be responsible in any way for any depreciation in the value of the
Collateral, nor shall any duty or responsibility whatsoever rest upon Secured
Party to take any steps to preserve rights against prior parties or to enforce
collection of the Collateral by legal proceedings or otherwise, the sole duty of
Secured Party, its successors and assigns, being to receive collections,
remittances and payments on such Collateral as and when made and received by
Secured Party and, as provided by the Credit Agreement, to apply the amount or
amounts so received, after deduction of any collection costs incurred, as
payment upon any of the Debt or to hold the same for the account and order of
Debtor.

     8.17 In the event Debtor instructs Secured Party, in writing or orally, to
deliver any or all of the Collateral to a third Person, and Secured Party agrees
to do so, the following conditions shall be conclusively deemed to be a part of
Secured Party's agreement, whether or not they are specifically mentioned to
Debtor at the time of such agreement: (i) Secured Party shall not assume any
responsibility for checking the genuineness or authenticity of any Person
purporting to be a messenger, employee or representative of such third Person to
whom Debtor has directed Secured Party to deliver the Collateral, or the
genuineness or authenticity of any document of instructions delivered by such
Person; (ii) Debtor will be considered by requesting any such delivery to have
assumed all risk of loss as to the Collateral; (iii) Secured Party's sole
responsibility will be to deliver the Collateral to the Person purporting to be
such third Person described by Debtor, or a messenger, employee or
representative thereof; and (iv) Secured Party and Debtor hereby expressly agree
that the foregoing actions by Secured Party shall constitute reasonable care.

     8.18 The pronouns used in this Agreement are in the masculine and neuter
genders but shall be construed as feminine, masculine or neuter as occasion may
request. "Secured Party", "Obligor" and "Debtor" as used in this Agreement
include the heirs, devisees, successors, administrators, personal
representatives, trustees, beneficiaries, conservators, receivers, and
successors and assigns of those parties.

     8.19 The section headings appearing in this Agreement have been inserted
for convenience only and shall be given no substantive meaning or significance
whatever in construing the terms and provisions of this Agreement. Terms used in
this Agreement which are defined in the Texas Uniform Commercial Code are used
with the meanings as therein defined. Wherever the term "including" or a similar
term is used in this Agreement, it shall be read as if it were written
"including by way of example only and without in any way limiting the generality
of the clause or concept referred to."

     8.20 THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE APPLICABLE LAWS OF THE STATE OF TEXAS (OTHER THAN THE CONFLICTS OF LAWS
PRINCIPLES THEREOF) AND THE UNITED STATES OF AMERICA FROM TIME TO TIME IN
EFFECT.

     8.21 Debtor agrees that, if at any time all or any part of any payment
previously applied by Secured Party to the Debt is or must be returned by
Secured Party, or recovered from Secured Party, for any reason (including the
order of any bankruptcy court), this Agreement shall automatically be reinstated
to the same effect, as if the prior application had not been made, and, in
addition, Debtor hereby agrees to indemnify Secured Party against, and to save
and hold Secured Party harmless from any required return by Secured Party, or
recovery from Secured Party, of any such payments because of its being deemed
preferential under applicable bankruptcy, receivership or insolvency laws, or
for any other reason.

     8.22 Secured Party may from time to time and at any time, without any
necessity for any notice to or consent by Debtor or any other Person, release
all or any part of the Collateral from the security interests of this Agreement,
with or without cause, including as a result of any determination by Secured
Party that the Collateral or any portion thereof contains or has been
contaminated by or releases or discharges any hazardous or toxic waste, material
or substance.

     8.23 This Agreement is given in renewal, amendment, replacement, and
restatement in its entirety (but not in novation, extinguishment or
satisfaction) of that certain Security Agreement (Personal Property) dated June
12, 1997, executed by and between Tidel Engineering, Inc. and Secured Party,
successor-in-interest to Texas Commerce Bank National Association, as amended by
that certain First Amendment to Security Agreement dated May 27, 1998, by and
between Tidel Engineering, Inc. and Secured Party (as amended, the "Prior
Agreement"). To the extent of any conflict between the terms of this Agreement
and the terms of the Prior Agreement, the terms of this Agreement shall control.

     8.24 THIS AGREEMENT REPRESENTS 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.

         2.1 This Agreement is made to secure all of the following debt and
obligations:

             (a) All Indebtedness at any time evidenced by the Notes, the
Applications, and any and all modifications, extensions, renewals,
rearrangements, replacements and increases of each thereof.

             (b) All other Obligations of Debtor, TCS or any other party
under or in connection with the Credit Agreement, this Agreement and the other
Loan Documents owed to Secured Party.

         2.2 The term "Debt" means and includes all of the Indebtedness and
other Obligations described or referred to in Section 2.1. The Debt includes
interest and all other Obligations accruing or arising after (a) commencement of

(it being the intention of Secured Party to not reinstate the liability of any
discharged Obligor, but only to confirm that the discharge of any Obligor from
liability for the Debt shall not effect all remaining Obligors' liability for
interest and other Obligations accruing or arising with respect to the Debt
after any such discharged Obligor has been released from liability for all or
any portion of the Debt. The

expenses incurred by Secured Party in enforcing any of the Loan Documents.

         TCS represents and warrants as follows:

         (a) TCS is the legal and equitable owner and holder of marketable title
to the Collateral free of any material adverse claim and free of any Lien except
only for the Liens granted hereby and those other Liens (if any) expressly
referred to, described in or permitted by this Agreement or any other Loan
Documents. Except with respect to Liens permitted by this Agreement or by the
terms of the other Loan Documents, TCS has not heretofore signed any financing
statement or other similar instrument directly or indirectly affecting the
Collateral or any part of it which has not been completely terminated of record,
and no such financing statement or other similar instrument signed by TCS is now
on file in any public office.

         (b) As of the date of this Agreement, the location of TCS is the
address set forth at the beginning of this Agreement and in this regard, TCS's
location is defined to mean (i) TCS's place of business if TCS has only one such
place of business; or (ii) TCS's chief executive office if TCS has more than one
place of business. As of the date of this Agreement, the primary books and
records of TCS with regard to the Collateral are maintained and kept at such
address of TCS set forth at the beginning of this Agreement.

         (c) No part of the Collateral consists or will consist of consumer
goods, farm products or timber and the like or accounts resulting from the sale
thereof.

         (d) TCS has the right to use, assign and pledge, without payment of any
amounts to any third parties (other than normal licensing fees payable to
licensors of prefabricated software programs currently utilized by TCS, if any),
any and all accounting, monitoring, billing, recordkeeping or other similar
types of systems, together with all related software, currently utilized by TCS
in its operations. Prior to commencement of any use by TCS of any custom
designed or similar types of accounting, monitoring, billing, recordkeeping or
other similar types of systems, together with all related software, TCS shall
cause any and all licensors thereof to consent in writing to the use by Secured
Party of such systems and related software upon payment by Secured Party to such
licensors of the amounts normally due and payable on a periodic basis by TCS to
such licensors in connection with TCS's day to day use and implementation of
such systems and related software (the form of such consents from the applicable
licensors to be upon terms and conditions reasonably acceptable to Secured
Party).

         (e) As of the date of this Agreement, TCS has not ever changed its name
whether by amendment of its organizational documents or otherwise, except as
disclosed in the Organizational Documents of TCS delivered to Secured Party in
connection with the execution and delivery of the Credit Agreement and all other
Loan Documents.

         (f) The Collateral is free from damage caused by fire or other
casualty.

         (g) None of the products manufactured and sold, nor any processes or
know-how used by TCS, presently infringe or are alleged to infringe, in any
material respect, any patent, trade secret, trademark, service mark, tradename,
copyright or other proprietary right of any other Person.

         (h) Except for Liens expressly permitted by this Agreement or any of
the other Loan Documents, the Liens of this Agreement will constitute valid and
perfected first and prior Liens on the Collateral when a financing statement
covering the Collateral is duly filed for record in the offices of the Secretary
of State of the State of Texas.

         (i) As of the date hereof, other than Inventory of TCS which is in
transit, all of the Inventory and Equipment of TCS is located at the locations
described on Schedule 1 attached hereto.

                                    ARTICLE 4
                                    COVENANTS

         4.1      TCS covenants and agrees with Secured Party as follows:

                  (a) TCS shall furnish to Secured Party such instruments as may
be required by Secured Party to assure the transferability of any Collateral
when and as often as may be reasonably requested by Secured Party.

                  (b) If the validity or priority of this Agreement or of any
material rights, titles, security interests or other interests created or
evidenced hereby shall be attacked, endangered or questioned or if any legal
proceedings are instituted with respect thereto, TCS will give prompt written
notice thereof to Secured Party and at TCS's own cost and expense will
diligently endeavor to cure any defect that may be developed or claimed, and
will take all necessary and proper steps for the defense of such legal
proceedings, and Secured Party (whether or not named as a party to legal
proceedings with respect thereto) is hereby authorized and empowered to take
such additional steps as in its reasonable judgment and discretion may be
necessary or proper for the defense of any such legal proceedings or the
protection of the validity or priority of this Agreement and the rights, titles,
security interests and other interests created or evidenced hereby, and all
expenses so incurred of every kind and character shall constitute sums advanced
pursuant to Section 4.2 of this Agreement.

                  (c) Notwithstanding the security interest in proceeds granted
herein, TCS will not, except as otherwise expressly permitted herein or in the
other Loan Documents, sell, lease, exchange, lend, rent, assign, license,
transfer or otherwise dispose of, or pledge, hypothecate or grant any Lien in,
or permit to exist any Lien against, all or any part of the Collateral or any
interest therein or permit any of the foregoing to occur or arise or permit
title to the Collateral, or any interest therein, to be vested in any other
party, in any manner whatsoever, by operation of law or otherwise, without the
prior written consent of Secured Party. Except as provided by the Loan Documents
or as otherwise permitted herein, TCS shall not, without the prior written
consent of Secured Party, (i) acquire any such Collateral under any arrangement
whereby the


SECURITY AGREEMENT (PERSONAL PROPERTY) - Page 5

<PAGE>   6



seller or any other person retains or acquires any security interest in such
Collateral or (ii) return or give possession of any such Collateral to any
supplier or any other Person except in the ordinary course of business. Subject
to the exercise of Secured Party's rights and remedies granted herein or in any
other Loan Document, TCS may use the Collateral in any lawful manner not
inconsistent with this Agreement or the other Loan Documents or with the terms
or conditions of any policy of insurance thereon and may also sell or lease such
Collateral in the ordinary course of business except as otherwise provided under
the other Loan Documents. A sale in the ordinary course of business does not
include a transfer in partial or total satisfaction of a debt. Subject to the
exercise of Secured Party's rights and remedies granted herein or in any other
Loan Document, TCS may also use and consume any raw materials or supplies, the
use and consumption of which are necessary to carry on the business of TCS.

                  (d) If any portion of the Collateral is now or hereafter
evidenced by any promissory notes, trade acceptances or other instruments for
the payment of money having an original principal or face amount in excess of
$10,000, TCS will immediately deliver them to Secured Party, appropriately
endorsed to Secured Party's order. Regardless of the form of endorsement, TCS
waives presentment, demand, notice of dishonor, protest and notice of protest.
After an Event of Default which is continuing, but prior to such delivery, such
Collateral shall be held in trust for the benefit of Secured Party and subject
to the Liens granted herein.

                  (e) TCS shall maintain property and liability insurance
policies covering the Collateral and claims related to the Collateral
("Collateral Insurance") in accordance with the requirements of Section 6.7 of
the Credit Agreement. TCS shall deliver certificates evidencing renewal of the
Collateral Insurance before termination of any insurance policies representing
Collateral Insurance. Upon request, TCS shall deliver certificates evidencing
the Collateral Insurance and copies of the underlying policies as they are
available. Promptly upon obtaining knowledge thereof, TCS shall notice Secured
Party of any casualty to the Collateral which exceeds $100,000 ("Material
Casualty"). At the request of Secured Party, TCS shall pursue claims for payment
related to the Material Casualty.

                  (f) Upon the receipt by Secured Party or TCS of any insurance
proceeds from insurance policies required to be maintained pursuant to Section
6.7 of the Credit Agreement on account of (1) each separate loss, damage or
injury to any Collateral in excess of $100,000 if no Default or Event of Default
shall have occurred which is continuing or (2) any separate loss, damage or
injury to any Collateral (regardless of the amount of loss, damage or injury) if
a Default or Event of Default shall have occurred which is continuing, such
insurance proceeds shall be promptly delivered and turned over to Secured Party
(if the same have not been previously received by Secured Party), and except as
otherwise specified below, such insurance proceeds shall be promptly applied by
Secured Party in payment of the Debt (such order and manner of application to he
at the discretion of Secured Party). With respect to such net insurance
proceeds, TCS may elect, by written notice delivered to Secured Party, not later
than the tenth day after receipt of such net proceeds by Secured Party or TCS,
to utilize and apply all or a portion of such net proceeds for the purpose of
replacing, repairing or restoring the relevant Collateral, and in such event,
any required application of such net proceeds against the Debt in accordance
with the preceding sentence shall be reduced dollar for dollar by the amount of
such election by TCS. Such an election by TCS shall not be effective, however,
unless (1) at the time



SECURITY AGREEMENT (PERSONAL PROPERTY) - Page 6

<PAGE>   7


of such election no Default or Event of Default shall have occurred which is
continuing, (2) TCS shall have certified to Secured Party that the net proceeds
of the insurance adjustment for such loss, damage or injury to Collateral,
together with other funds available to TCS, shall be sufficient to complete such
contemplated replacement, repair or restoration in accordance with all
applicable laws, regulations and ordinances, and (3) if the amount of the net
proceeds in question exceeds $100,000, TCS shall have obtained the written
consent of the Secured Party to such use and application of such insurance
proceeds.

                  (g) In the event of a valid election by TCS under Section
4.1(f) above to utilize all or a portion of such insurance proceeds to replace,
repair or restore the relevant Collateral, upon the request of Secured Party,
TCS shall place into an account under Secured Party's control (the "Insurance
Proceeds Account") the amount of net insurance proceeds to be utilized for such
contemplated replacement, repair or restoration, pursuant to agreements in form,
scope and substance reasonably satisfactory to Secured Party (including a pledge
of such Insurance Proceeds Account as additional security for the Debt). The
Insurance Proceeds Account, including all earnings thereon, if any, shall be
available to TCS solely for the replacement, repair or restoration of the
Collateral suffering the applicable injury, loss or damage; provided, however,
that at any time that a Default or Event of Default shall occur and be
continuing, the balance of the Insurance Proceeds Account, together with all
earnings thereon, may be immediately applied by Secured Party to repay the Debt
in such order as Secured Party shall elect in its discretion. Secured Party
shall be entitled to require proof, as a condition to TCS making of any
withdrawal from the Insurance Proceeds Account, that the amount of such
withdrawal is being applied for the purposes permitted hereunder. Additionally,
any proceeds of the Insurance Proceeds Account may be made available and
advanced by Secured Party directly to TCS, or directly to suppliers,
manufacturers, contractors and other persons entitled to payment in accordance
with and subject to reasonable conditions to disbursements as Secured Party may
impose to assure that such replacement, repair or restoration of the relevant
Collateral is paid for and performed and that no Liens arise by reason thereof.

                  (h) No Inventory nor Equipment shall be located at any
location, other than the locations set forth on Schedule 1 attached hereto,
which has not been disclosed in writing to Secured Party in advance of such
Inventory or Equipment being located at such location and for which Financing
Statements, and landlord subordinations or warehousemens' agreements, as the
case may be, (if such locations are not owned by TCS) covering such portion of
the Inventory or Equipment, as the case may be, have not been executed and
delivered by TCS and filed for record with the appropriate Governmental
Authority necessary to perfect the Liens granted hereby.

                  (i) TCS agrees to defend the Collateral and its proceeds
against all claims and demands of any Person at any time claiming the
Collateral.

         4.2 If TCS fails to comply with any of its agreements, covenants or
obligations under this Agreement or any other Loan Document, after giving effect
to any applicable cure period, Secured Party (in TCS's name or in Secured
Party's own name) may perform them or cause them to be performed for the account
and at the expense of TCS, but shall have no obligation to perform any of them
or cause them to be performed. Any and all expenses thus incurred or paid



SECURITY AGREEMENT (PERSONAL PROPERTY) - Page 7

<PAGE>   8



by Secured Party shall be TCS's obligations to Secured Party due and payable on
demand, or if no demand is sooner made, then they shall be due on or before four
(4) years after the respective dates on which they were incurred, and each shall
bear interest from the date one (1) Business Day after Secured Party demands
payment for such amounts until the date TCS repays such amounts to Secured
Party, at the Past Due Rate. Upon making any such payment or incurring any such
expense, Secured Party shall be fully and automatically subrogated to all of the
rights of the person, corporation or body politic receiving such payment. Any
amounts owing by TCS to Secured Party pursuant to this or any other provision of
this Agreement shall automatically and without notice be and become a part of
the Debt and shall be secured by this and all other instruments securing the
Debt. The amount and nature of any such expense and the time when it was paid
shall be fully established by the affidavit of Secured Party or any of Secured
Party's officers or agents. The exercise of the privileges granted to Secured
Party in this Section shall in no event be considered or constitute a cure of
the default or a waiver of Secured Party's right at any time after an Event of
Default to declare the Debt to be at once due and payable, but is cumulative of
such right and of all other rights given by this Agreement, the Credit
Agreement, the Notes and the Loan Documents and of all rights given Secured
Party by law.

                                    ARTICLE 5
                     ASSIGNMENT OF PAYMENTS; CERTAIN POWERS
                         OF SECURED PARTY; NO ASSUMPTION

         5.1 Upon the occurrence of an Event of Default and so long as it is
continuing and has not been expressly waived by Secured Party in writing,
Secured Party may request TCS to notify each account debtor and each other
Person (each a "Collateral Obligor") obligated to make payment in respect of any
of the Collateral of the Liens in such Collateral granted herein and instruct
such Collateral Obligor to pay over to Secured Party, all or any part of the
Collateral without making any inquiries as to the status or balance of TCS and
without any notice to or further consent of TCS. If TCS does not promptly comply
with such request, Secured Party may, but shall not be obligated to, directly
notify each such Collateral Obligor of the Liens in the Collateral granted
herein and instruct such Collateral Obligor to pay over to Secured Party, all or
any part of the Collateral without making any inquiries as to the status or
balance of TCS and without any notice to or further consent of TCS.

         5.2 The powers conferred on Secured Party pursuant to this Article 5
are conferred solely to protect Secured Party's interest in the Collateral and
shall not impose any duty or obligation on Secured Party to perform any of the
powers herein conferred. Additionally, the powers conferred on Secured Party
pursuant to this Article 5 are cumulative of all other similar, related or
additional powers conferred on Secured Party by the terms and provisions of
Section 9.21 of the Credit Agreement and are not intended to limit or restrict
in any manner whatsoever any of such powers and rights conferred on Secured
Party under the terms and provisions of the Credit Agreement or any other Loan
Documents. No exercise of any of such rights provided for in this Article 5 or
in the Credit Agreement shall constitute a retention of collateral in
satisfaction of the indebtedness as provided for in Section 9.505 of the Uniform
Commercial Code of Texas or the state or states where the applicable Collateral
is located.

                                    ARTICLE 6
                                EVENTS OF DEFAULT

         An Event of Default under the Credit Agreement shall constitute an
Event of Default (herein so called) under this Agreement.

                                    ARTICLE 7
                          REMEDIES IN EVENT OF DEFAULT

         7.1 In addition to the other rights and remedies provided for in the
Credit Agreement, upon the occurrence and during the continuation of an Event of
Default:

                  (a) Secured Party is authorized, in any legal manner and
without breach of the peace, to take possession of the Collateral (TCS HEREBY
WAIVES ALL CLAIMS FOR DAMAGES ARISING FROM OR CONNECTED WITH ANY SUCH TAKING,
EXCEPT AS MAY BE CAUSED BY THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SECURED
PARTY) and of all books, records and accounts relating thereto and to exercise
without interference from TCS any and all rights which TCS has with respect to
the management, possession, operation, protection, preservation, distribution or
resale of the Collateral, including the right to sell or rent the same for the
account of TCS and to deduct from such sale proceeds or such rents all costs,
expenses and liabilities of every character incurred by Secured Party in
collecting such sale proceeds or such rents, and in managing, operating,
maintaining, protecting or preserving the Collateral and to apply the remainder
of such sales proceeds or such rents on the Debt in such manner as Secured Party
may elect. Before any sale, Secured Party may, at its option, complete the
processing of any of the Collateral and/or repair or recondition the same to
such extent as Secured Party may deem advisable and any reasonable sums expended
therefor by Secured Party shall be reimbursed by TCS. Secured Party may take
possession of TCS's premises to complete such processing, repairing and/or
reconditioning, using the facilities and other property of TCS to do so, to
store any Collateral and to conduct any sale as provided for herein, all without
compensation to TCS. All costs, expenses, and liabilities incurred by Secured
Party in collecting such sales proceeds or such rents, or in managing,
operating, maintaining, protecting or preserving such properties, or in
processing, repairing and/or reconditioning the Collateral if not paid out of
such sales proceeds or such rents as hereinabove provided, shall constitute a
demand obligation owing by TCS and shall bear interest from the date of
expenditure until paid at the Past Due Rate, all of which shall constitute a
portion of the Debt. If necessary to obtain the possession provided for above,
Secured Party may invoke any and all legal remedies to dispossess TCS, including
specifically one or more actions for forcible entry and detainer. In connection
with any action taken by Secured Party pursuant to this paragraph, Secured Party
shall not be liable for any loss sustained by TCS resulting from any failure to
sell or let the Collateral, or any part thereof, or from any other act or
omission of Secured Party with respect to the Collateral unless such loss is
caused by the gross negligence or willful misconduct of Secured Party, nor shall
Secured Party be obligated to perform or discharge any obligation, duty, or
liability under any sale or lease agreement covering the Collateral or any part
thereof or under or by reason of this instrument or the exercise of rights or
remedies hereunder.

                  (b) Secured Party may, without notice except as hereinafter
provided, sell the Collateral or any part thereof at public or private sale
(with or without appraisal or having the



SECURITY AGREEMENT (PERSONAL PROPERTY) - Page 9



<PAGE>   10



Collateral at the place of sale) for cash, upon credit, or for future delivery,
and at such price or prices as Secured Party may deem best, and Secured Party
may be the purchaser of any and all of the Collateral so sold and may apply upon
the purchase price therefor any of the Debt and thereafter hold the same
absolutely free from any right or claim of whatsoever kind. In any such public
or private sale, Secured Party may (but shall not be obligated to) submit a bid
in the form of a credit against the Debt owed to Secured Party, and Secured
Party or its designee may accept title to property purchased at such public or
private sale. Upon any such sale Secured Party shall have the right to deliver,
assign and transfer to the purchaser thereof the Collateral so sold. Each
purchaser at any such sale shall hold the property sold absolutely free from any
claim or right of whatsoever kind, including any equity or right of redemption,
stay or appraisal which TCS has or may have under any rule of law or statute now
existing or hereafter adopted. To the extent notice is required by applicable
law, Secured Party shall give TCS written notice at the address set forth herein
(which shall satisfy any requirement of notice or reasonable notice in any
applicable statute) of Secured Party's intention to make any such public or
private sale. Such notice (if any is required by applicable law) shall be
personally delivered or mailed, postage prepaid, at least ten (10) calendar days
before the date fixed for a public sale, or at least (10) calendar days before
the date after which the private sale or other disposition is to be made, unless
the Collateral is of a type customarily sold on a recognized market, is
perishable or threatens to decline speedily in value. Such notice (if any is
required by applicable law), in case of public sale, shall state the time and
place fixed for such sale or, in case of private sale or other disposition other
than a public sale, the time after which the private sale or other such
disposition is to be made. Any public sale shall be held at such time or times,
within the ordinary business hours and at such place or places, as Secured Party
may fix in the notice of such sale. At any sale, the Collateral may be sold in
one lot as an entirety or in separate parcels as Secured Party may determine.
Secured Party shall not be obligated to make any sale pursuant to any such
notice. Secured Party may, without notice or publication, adjourn any public or
private sale or cause the same to be adjourned from time to time by announcement
at any time and place fixed for the sale, and such sale may be made at any time
or place to which the same may be so adjourned. In case of any sale of all or
any part of the Collateral on credit or for future delivery, the Collateral so
sold may be retained by Secured Party until the selling price is paid by the
purchaser thereof, but Secured Party shall not incur liability in case of the
failure of such purchaser to take up and pay for the Collateral so sold, and in
case of any such failure, such Collateral may again be sold upon like notice.
Each and every method of disposition described in this Section shall constitute
disposition in a commercially reasonable manner. Each Obligor, to the extent
applicable, shall remain liable for any deficiency.

                  (c) Secured Party shall have all the rights of a secured party
after default under the Uniform Commercial Code of the state or states where the
applicable Collateral is situated, and in conjunction with, in addition to or in
substitution for those rights and remedies:

                           (i) Secured Party may require TCS to assemble the
         Collateral and make it available at a place Secured Party designates
         which is mutually convenient to allow Secured Party to take possession
         or dispose of the Collateral; and

                           (ii) it shall not be necessary that Secured Party
         take possession of the Collateral or any part thereof before the time
         that any sale pursuant to the provisions of



SECURITY AGREEMENT (PERSONAL PROPERTY) - Page 10

<PAGE>   11




         this Article is conducted and it shall not be necessary that the
         Collateral or any part thereof be present at the location of such
         sale; and

                           (iii) before application of proceeds of disposition
         of the Collateral to the Debt, such proceeds shall be applied to the
         reasonable expenses of retaking, holding, preparing for sale or lease,
         selling, leasing, licensing, sublicensing and the like, as well as
         reasonable attorneys' fees and legal expenses incurred by Secured
         Party, each Obligor, to the extent applicable, to remain liable for any
         deficiency; and

                           (iv) the sale by Secured Party of less than the whole
         of the Collateral shall not exhaust the rights of Secured Party
         hereunder, and Secured Party is specifically empowered to make
         successive sale or sales hereunder until the whole of the Collateral
         shall be sold; and, if the proceeds of such sale of less than the whole
         of the Collateral shall be less than the aggregate of the Debt, this
         Agreement and the security interest created hereby shall remain in full
         force and effect as to the unsold portion of the Collateral just as
         though no sale had been made; and

                           (v) in the event any sale hereunder is not completed
         or is defective in the reasonable opinion of Secured Party, such sale
         shall not exhaust the rights of Secured Party hereunder and Secured
         Party shall have the right to cause a subsequent sale or sales to be
         made hereunder; and

                           (vi) any and all statements of fact made in any bill
         of sale or assignment or other instrument evidencing any foreclosure
         sale hereunder shall be taken as rebuttable evidence of the truth of
         the facts so stated; and

                           (vii) Secured Party may appoint or delegate any one
         or more persons as agent to perform any act or acts necessary or
         incident to any sale held by Secured Party, including the sending of
         notices and the conduct of sale, but in the name and on behalf of
         Secured Party; and

                           (viii) demand of performance, advertisement and
         presence of property at sale are hereby WAIVED and Secured Party is
         hereby authorized to sell hereunder any evidence of debt it may hold as
         security for the Debt. Except as provided herein or in any other Loan
         Document, all demands and presentments of any kind or nature are
         expressly WAIVED by TCS. TCS WAIVES the right to require Secured Party
         to pursue any other remedy for the benefit of TCS and agrees that
         Secured Party may proceed against any Obligor for the amount of the
         Debt owed to Secured Party without taking any action against any other
         Obligor or any other person or entity and without selling or otherwise
         proceeding against or applying any of the Collateral in Secured Party's
         possession.

                  (d) Secured Party may apply to a court of competent
jurisdiction for the appointment of a receiver, or a receiver and manager, over
TCS, or any or all of the Collateral, with such duties, powers and obligations
as the court making such appointment shall confirm,


SECURITY AGREEMENT (PERSONAL PROPERTY) - Page 11


<PAGE>   12




and TCS hereby irrevocably consents to the appointment of such receiver or such
receiver and manager.

         7.2 All remedies expressly provided for in the Agreement are cumulative
of any and all other remedies existing at law or in equity and are cumulative of
any and all other remedies provided for in any other instrument securing the
payment of the Debt, or any part thereof, or otherwise benefiting Secured Party,
and the resort to any remedy provided for hereunder or under any such other
instrument or provided for by law shall not prevent the concurrent or subsequent
employment of any other appropriate remedy or remedies.

         7.3 Secured Party may resort to any security given by this Agreement or
to any other security now existing or hereafter given to secure the payment of
the Debt, in whole or in part, and in such portions and in such order as may
seem best to Secured Party in its sole and uncontrolled discretion, and any such
action shall not in anywise be considered as a waiver of any of the rights,
benefits or security interests evidenced by this Agreement.

         7.4 To the full extent TCS may do so, TCS agrees that TCS will not at
any time insist upon, plead, claim or take the benefit or advantage of any law
now or hereafter in force providing for any appraisement, valuation, stay,
extension or redemption, and TCS, for TCS, TCS's successors, receivers, trustees
and assigns, and for any and all persons ever claiming any interest in the
Collateral, to the extent permitted by law, hereby WAIVE and release all rights
of redemption, valuation, appraisement, stay of execution, notice of intention
to mature or to declare due the whole of the Debt, notice of election to mature
or to declare due the whole of the Debt and all rights to a marshaling of the
assets of TCS, including the Collateral, or to a sale in inverse order of
alienation in the event of foreclosure of the security interest hereby created.

                                    ARTICLE 8
                              ADDITIONAL AGREEMENTS

         8.1 Subject to the automatic reinstatement provisions of Section 8.21
below, upon full satisfaction of the Debt, complete performance of all of the
obligations of the Obligors under the Loan Documents and final termination of
Secured Party's obligations, if any, to make any further advances under any Note
or to provide any other financial accommodations to any Obligor, all rights
under this Agreement shall terminate and the Collateral shall become wholly
clear of the security interest evidenced hereby, and upon written request by TCS
such security interest shall be released by Secured Party in due form and at
TCS's cost.

         8.2 Secured Party may waive any default without waiving any other prior
or subsequent default. Secured Party may remedy any default without waiving the
default remedied. The failure by Secured Party to exercise any right, power or
remedy upon any default shall not be construed as a waiver of such default or as
a waiver of the right to exercise any such right, power or remedy at a later
date. No single or partial exercise by Secured Party of any right, power or
remedy hereunder shall exhaust the same or shall preclude any other or further
exercise thereof, and every such right, power or remedy hereunder may be
exercised at any time and from time to time. No modification or waiver of any
provision hereof nor consent to any departure by TCS therefrom shall in any
event be effective unless the same shall be in writing




SECURITY AGREEMENT (PERSONAL PROPERTY) - Page 12

<PAGE>   13





and signed by Secured Party, and then such waiver or consent shall be effective
only in the specific instances, for the purpose for which given and to the
extent therein specified. No notice to nor demand on TCS in any case shall of
itself entitle TCS to any other or further notice or demand in similar or other
circumstances. Acceptance by Secured Party of any payment in an amount less than
the amount then due on the Debt shall be deemed an acceptance on account only
and shall not in any way affect the existence of a default hereunder.

         8.3 Subject to Section 9.11 of the Credit Agreement, Secured Party may
at any time and from time to time in writing (a) waive compliance by TCS with
any covenant herein made by TCS to the extent and in the manner specified in
such writing; (b) consent to TCS's doing any act which hereunder TCS is
prohibited from doing, or consent to TCS's failing to do any act which hereunder
TCS is required to do, to the extent and in the manner specified in such
writing; (c) release any part of the Collateral, or any interest therein, from
the security interest of this Agreement; or (d) release any Person liable,
either directly or indirectly, for the Debt or for any covenant herein or in any
other instrument now or hereafter securing the payment of the Debt, without
impairing or releasing the liability of any other Person. No such act shall in
any way impair the rights of Secured Party hereunder except to the extent
specifically agreed to by Secured Party in such writing.

         8.4 Secured Party shall not be required to take any steps necessary to
preserve any rights against prior parties to any of the Collateral.

         8.5 The Liens and other rights of Secured Party hereunder shall not be
impaired by any indulgence, moratorium or release granted by Secured Party,
including but not limited to (a) any renewal, extension or modification which
Secured Party may grant with respect to the Debt; (b) any surrender compromise,
release, renewal, extension, exchange or substitution which Secured Party may
grant in respect of any item of the Collateral, or any part thereof or any
interest therein; or (c) any release or indulgence granted to any endorser,
guarantor or surety of the Debt.

         8.6 A carbon, photographic or other reproduction of this Agreement or
of any financing statement relating to this Agreement shall be sufficient as a
financing statement. TCS will cause all financing statements and continuation
statements relating hereto to be recorded, filed, re-recorded and refiled in
such manner and in such places as Secured Party shall reasonably request and
will pay all such recording, filing, re-recording, and refiling taxes, fees and
other charges.

         8.7 This Agreement may be executed in several identical counterparts
and by the parties hereto on separate counterparts, and each counterpart, when
so executed and delivered, shall constitute an original instrument, and all such
separate counterparts shall constitute but one and the same instrument.

         8.8 In the event the ownership of the Collateral or any part thereof
becomes vested in a Person other than TCS, Secured Party may, without notice to
TCS deal with such successor or successors in interest with reference to this
Agreement and to the Debt in the same manner as with TCS, without in any way
vitiating or discharging TCS's liability hereunder or upon the




SECURITY AGREEMENT (PERSONAL PROPERTY) - Page 13

Debt. No sale of the Collateral, and no forbearance on the part of Secured Party
and no extension of the time for the payment of the Debt given by Secured Party
shall operate to release, discharge, modify, change or affect, in whole or in
part, the liability of TCS hereunder for the payment of the Debt or the
liability of any other person hereunder for the payment of the Debt, except as
agreed to in writing by Secured Party or as expressly provided in the Credit
Agreement.

         8.9 Any other or additional security taken for the payment of any of
the Debt shall not in any manner affect the security given by this Agreement.

         8.10 To the extent that proceeds of the Debt are used to pay
indebtedness secured by any outstanding Lien against the Collateral, such
proceeds have been advanced by Secured Party at TCS's request, and Secured Party
shall be subrogated to any and all Liens owned by any owner or holder of such
outstanding Lien, irrespective of whether said Lien is released.

         8.11 If any part of the Debt cannot be lawfully secured by this
Agreement, or if the Liens of this Agreement cannot be lawfully enforced to pay
any part of the Debt, then and in either such event, at the option of Secured
Party, all payments on the Debt shall be deemed to have been first applied
against that part of the Debt.

         8.12 Subject to Section 9.11 of the Credit Agreement, this Agreement
shall not be changed orally but shall be changed only by agreement in writing
signed by TCS and Secured Party. No course of dealing between the parties, no
usage of trade and no parole or extrinsic evidence of any nature shall be used
to supplement or modify any of the terms or provisions of this Agreement.

         8.13 Any notice, request or other communication required or permitted
to be given hereunder shall be given as provided in the Credit Agreement.

         8.14 This Agreement shall be binding upon TCS, and the trustees,
receivers, successors and assigns of TCS, including all successors in interest
of TCS in and to all or any part of the Collateral, and shall benefit Secured
Party and its successors and assigns.

         8.15 If any provision of this Agreement is held to be illegal, invalid
or unenforceable under present or future laws, the legality, validity and
enforceability of the remaining provisions of this Agreement shall not be
affected thereby, and this Agreement shall be liberally construed so as to carry
out the intent of the parties to it. Each waiver in this Agreement is subject to
the overriding and controlling rule that it shall be effective only if and to
the extent that (a) it is not prohibited by applicable law and (b) applicable
law neither provides for nor allows any material sanctions to be imposed against
Secured Party for having bargained for and obtained it.

         8.16 Secured Party shall be deemed to have exercised reasonable care in
the custody and preservation of any of the Collateral in its possession if it
takes such action for that purpose as TCS requests in writing, but failure of
Secured Party to comply with such request shall not of itself be deemed a
failure to have exercised reasonable care, and no failure of Secured Party to
take any action so requested by TCS shall be deemed a failure to exercise
reasonable care in the


SECURITY AGREEMENT (PERSONAL PROPERTY) - Page 14


<PAGE>   15



custody or preservation of such Collateral. Secured Party shall not be
responsible in any way for any depreciation in the value of the Collateral, nor
shall any duty or responsibility whatsoever rest upon Secured Party to take any
steps to preserve rights against prior parties or to enforce collection of the
Collateral by legal proceedings or otherwise, the sole duty of Secured Party,
its successors and assigns, being to receive collections, remittances and
payments on such Collateral as and when made and received by Secured Party and,
as provided by the Credit Agreement, to apply the amount or amounts so received,
after deduction of any collection costs incurred, as payment upon any of the
Debt or to hold the same for the account and order of TCS.

         8.17 In the event TCS instructs Secured Party, in writing or orally, to
deliver any or all of the Collateral to a third Person, and Secured Party agrees
to do so, the following conditions shall be conclusively deemed to be a part of
Secured Party's agreement, whether or not they are specifically mentioned to TCS
at the time of such agreement: (i) Secured Party shall not assume any
responsibility for checking the genuineness or authenticity of any Person
purporting to be a messenger, employee or representative of such third Person to
whom TCS has directed Secured Party to deliver the Collateral, or the
genuineness or authenticity of any document of instructions delivered by such
Person; (ii) TCS will be considered by requesting any such delivery to have
assumed all risk of loss as to the Collateral; (iii) Secured Party's sole
responsibility will be to deliver the Collateral to the Person purporting to be
such third Person described by TCS, or a messenger, employee or representative
thereof; and (iv) Secured Party and TCS hereby expressly agree that the
foregoing actions by Secured Party shall constitute reasonable care.

         8.18 The pronouns used in this Agreement are in the masculine and
neuter genders but shall be construed as feminine, masculine or neuter as
occasion may request. "Secured Party", "Obligor" and "TCS" as used in this
Agreement include the heirs, devisees, successors, administrators, personal
representatives, trustees, beneficiaries, conservators, receivers, and
successors and assigns of those parties.

         8.19 The section headings appearing in this Agreement have been
inserted for convenience only and shall be given no substantive meaning or
significance whatever in construing the terms and provisions of this Agreement.
Terms used in this Agreement which are defined in the Texas Uniform Commercial
Code are used with the meanings as therein defined. Wherever the term
"including" or a similar term is used in this Agreement, it shall be read as if
it were written "including by way of example only and without in any way
limiting the generality of the clause or concept referred to."

         8.20 THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE APPLICABLE LAWS OF THE STATE OF TEXAS (OTHER THAN THE CONFLICTS OF LAWS
PRINCIPLES THEREOF) AND THE UNITED STATES OF AMERICA FROM TIME TO TIME IN
EFFECT.

         8.21 TCS agrees that, if at any time all or any part of any payment
previously applied by Secured Party to the Debt is or must be returned by
Secured Party, or recovered from Secured Party, for any reason (including the
order of any bankruptcy court), this Agreement shall automatically be reinstated
to the same effect, as if the prior application had not been made, and, in
addition, TCS hereby agrees to indemnify Secured Party against, and to save and
hold Secured

Party harmless from any required return by Secured Party, or recovery from
Secured Party, of any such payments because of its being deemed preferential
under applicable bankruptcy, receivership or insolvency laws, or for any other
reason.

         8.22 Secured Party may from time to time and at any time, without any
necessity for any notice to or consent by TCS or any other Person, release all
or any part of the Collateral from the security interests of this Agreement,
with or without cause, including as a result of any determination by Secured
Party that the Collateral or any portion thereof contains or has been
contaminated by or releases or discharges any hazardous or toxic waste, material
or substance.

         8.23 THIS AGREEMENT REPRESENTS 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.

         2.1 This Agreement is made to secure all of the following debt and
obligations:

                  (a) All Indebtedness at any time evidenced by the Notes, the

rearrangements, replacements and increases of each thereof.

                  (b) All other Obligations of Debtor, TSI or any other party
under or in connection with the Credit Agreement, this Agreement and the other
Loan Documents owed to Secured Party.

         2.2 The term "Debt" means and includes all of the Indebtedness and
other Obligations described or referred to in Section 2.1. The Debt includes
interest and all other Obligations accruing or arising after (a) commencement of

                         REPRESENTATIONS AND WARRANTIES

         TSI represents and warrants as follows:

         (a) TSI is the legal and equitable owner and holder of marketable title
to the Collateral free of any material adverse claim and free of any Lien except
only for the Liens granted hereby and those other Liens (if any) expressly
referred to, described in or permitted by this Agreement or any other Loan
Documents. Except with respect to Liens permitted by this Agreement or by the
terms of the other Loan Documents, TSI has not heretofore signed any financing
statement or other similar instrument directly or indirectly affecting the
Collateral or any part of it which has not been completely terminated of record,
and no such financing statement or other similar instrument signed by TSI is now
on file in any public office.

         (b) As of the date of this Agreement, the location of TSI is the
address set forth at the beginning of this Agreement and in this regard, TSI's
location is defined to mean (i) TSI's place of business if TSI has only one such
place of business; or (ii) TSI's chief executive office if TSI has more than one
place of business. As of the date of this Agreement, the primary books and
records of TSI with regard to the Collateral are maintained and kept at such
address of TSI set forth at the beginning of this Agreement.

         (c) No part of the Collateral consists or will consist of consumer
goods, farm products or timber and the like or accounts resulting from the sale
thereof.

         (d) TSI has the right to use, assign and pledge, without payment of any
amounts to any third parties (other than normal licensing fees payable to
licensors of prefabricated software programs currently utilized by TSI, if any),
any and all accounting, monitoring, billing, recordkeeping or other similar
types of systems, together with all related software, currently utilized by TSI
in its operations. Prior to commencement of any use by TSI of any custom
designed or similar types of accounting, monitoring, billing, recordkeeping or
other similar types of systems, together with all related software, TSI shall
cause any and all licensors thereof to consent in writing to the use by Secured
Party of such systems and related software upon payment by Secured Party to such
licensors of the amounts normally due and payable on a periodic basis by TSI to
such licensors in connection with TSI's day to day use and implementation of
such systems and related software (the form of such consents from the applicable
licensors to be upon terms and conditions reasonably acceptable to Secured
Party).

         (e) As of the date of this Agreement, TSI has not ever changed its name
whether by amendment of its organizational documents or otherwise, except as
disclosed in the Organizational Documents of TSI delivered to Secured Party in
connection with the execution and delivery of the Credit Agreement and all other
Loan Documents.

         (f) The Collateral is free from damage caused by fire or other
casualty.


SECURITY AGREEMENT (Personal Property) - Page 4

<PAGE>   5


         (g) None of the products manufactured and sold, nor any processes or
know-how used by TSI, presently infringe or are alleged to infringe, in any
material respect, any patent, trade secret, trademark, service mark, tradename,
copyright or other proprietary right of any other Person.

         (h) Except for Liens expressly permitted by this Agreement or any of
the other Loan Documents, the Liens of this Agreement will constitute valid and
perfected first and prior Liens on the Collateral when a financing statement
covering the Collateral is duly filed for record in the offices of the Secretary
of State of the State of Texas.

         (i) As of the date hereof, other than Inventory of TSI which is in
transit, all of the Inventory and Equipment of TSI is located at the locations
described on Schedule 1 attached hereto.

                                    ARTICLE 4
                                    COVENANTS

         4.1      TSI covenants and agrees with Secured Party as follows:

                  (a) TSI shall furnish to Secured Party such instruments as may
be required by Secured Party to assure the transferability of any Collateral
when and as often as may be reasonably requested by Secured Party.

                  (b) If the validity or priority of this Agreement or of any
material rights, titles, security interests or other interests created or
evidenced hereby shall be attacked, endangered or questioned or if any legal
proceedings are instituted with respect thereto, TSI will give prompt written
notice thereof to Secured Party and at TSI's own cost and expense will
diligently endeavor to cure any defect that may be developed or claimed, and
will take all necessary and proper steps for the defense of such legal
proceedings, and Secured Party (whether or not named as a party to legal
proceedings with respect thereto) is hereby authorized and empowered to take
such additional steps as in its reasonable judgment and discretion may be
necessary or proper for the defense of any such legal proceedings or the
protection of the validity or priority of this Agreement and the rights, titles,
security interests and other interests created or evidenced hereby, and all
expenses so incurred of every kind and character shall constitute sums advanced
pursuant to Section 4.2 of this Agreement.

                  (c) Notwithstanding the security interest in proceeds granted
herein, TSI will not, except as otherwise expressly permitted herein or in the
other Loan Documents, sell, lease, exchange, lend, rent, assign, license,
transfer or otherwise dispose of, or pledge, hypothecate or grant any Lien in,
or permit to exist any Lien against, all or any part of the Collateral or any
interest therein or permit any of the foregoing to occur or arise or permit
title to the Collateral, or any interest therein, to be vested in any other
party, in any manner whatsoever, by operation of law or otherwise, without the
prior written consent of Secured Party. Except as provided by the Loan Documents
or as otherwise permitted herein, TSI shall not, without the prior written
consent of Secured Party, (i) acquire any such Collateral under any arrangement
whereby the


SECURITY AGREEMENT (Personal Property) - Page 5

seller or any other person retains or acquires any security interest in such
Collateral or (ii) return or give possession of any such Collateral to any
supplier or any other Person except in the ordinary course of business. Subject
to the exercise of Secured Party's rights and remedies granted herein or in any
other Loan Document, TSI may use the Collateral in any lawful manner not
inconsistent with this Agreement or the other Loan Documents or with the terms
or conditions of any policy of insurance thereon and may also sell or lease such
Collateral in the ordinary course of business except as otherwise provided under
the other Loan Documents. A sale in the ordinary course of business does not
include a transfer in partial or total satisfaction of a debt. Subject to the
exercise of Secured Party's rights and remedies granted herein or in any other
Loan Document, TSI may also use and consume any raw materials or supplies, the
use and consumption of which are necessary to carry on the business of TSI.

                  (d) If any portion of the Collateral is now or hereafter
evidenced by any promissory notes, trade acceptances or other instruments for
the payment of money having an original principal or face amount in excess of
$10,000, TSI will immediately deliver them to Secured Party, appropriately
endorsed to Secured Party's order. Regardless of the form of endorsement, TSI
waives presentment, demand, notice of dishonor, protest and notice of protest.
After an Event of Default which is continuing, but prior to such delivery, such
Collateral shall be held in trust for the benefit of Secured Party and subject
to the Liens granted herein.

                  (e) TSI shall maintain property and liability insurance
policies covering the Collateral and claims related to the Collateral
("Collateral Insurance") in accordance with the requirements of Section 6.7 of
the Credit Agreement. TSI shall deliver certificates evidencing renewal of the
Collateral Insurance before termination of any insurance policies representing
Collateral Insurance. Upon request, TSI shall deliver certificates evidencing
the Collateral Insurance and copies of the underlying policies as they are
available. Promptly upon obtaining knowledge thereof, TSI shall notice Secured
Party of any casualty to the Collateral which exceeds $100,000 ("Material
Casualty"). At the request of Secured Party, TSI shall pursue claims for payment
related to the Material Casualty.

                  (f) Upon the receipt by Secured Party or TSI of any insurance
proceeds from insurance policies required to be maintained pursuant to Section
6.7 of the Credit Agreement on account of (1) each separate loss, damage or
injury to any Collateral in excess of $100,000 if no Default or Event of Default
shall have occurred which is continuing or (2) any separate loss, damage or
injury to any Collateral (regardless of the amount of loss, damage or injury) if
a Default or Event of Default shall have occurred which is continuing, such
insurance proceeds shall be promptly delivered and turned over to Secured Party
(if the same have not been previously received by Secured Party), and except as
otherwise specified below, such insurance proceeds shall be promptly applied by
Secured Party in payment of the Debt (such order and manner of application to he
at the discretion of Secured Party). With respect to such net insurance
proceeds, TSI may elect, by written notice delivered to Secured Party, not later
than the tenth day after receipt of such net proceeds by Secured Party or TSI,
to utilize and apply all or a portion of such net proceeds for the purpose of
replacing, repairing or restoring the relevant Collateral, and in such event,
any required application of such net proceeds against the Debt in accordance
with the preceding sentence shall be reduced dollar for dollar by the amount of
such election by TSI. Such an election by TSI shall not be effective, however,
unless (1) at the time


SECURITY AGREEMENT (Personal Property) - Page 6

<PAGE>   7


of such election no Default or Event of Default shall have occurred which is
continuing, (2) TSI shall have certified to Secured Party that the net proceeds
of the insurance adjustment for such loss, damage or injury to Collateral,
together with other funds available to TSI, shall be sufficient to complete such
contemplated replacement, repair or restoration in accordance with all
applicable laws, regulations and ordinances, and (3) if the amount of the net
proceeds in question exceeds $100,000, TSI shall have obtained the written
consent of the Secured Party to such use and application of such insurance
proceeds.

                  (g) In the event of a valid election by TSI under Section
4.1(f) above to utilize all or a portion of such insurance proceeds to replace,
repair or restore the relevant Collateral, upon the request of Secured Party,
TSI shall place into an account under Secured Party's control (the "Insurance
Proceeds Account") the amount of net insurance proceeds to be utilized for such
contemplated replacement, repair or restoration, pursuant to agreements in form,
scope and substance reasonably satisfactory to Secured Party (including a pledge
of such Insurance Proceeds Account as additional security for the Debt). The
Insurance Proceeds Account, including all earnings thereon, if any, shall be
available to TSI solely for the replacement, repair or restoration of the
Collateral suffering the applicable injury, loss or damage; provided, however,
that at any time that a Default or Event of Default shall occur and be
continuing, the balance of the Insurance Proceeds Account, together with all
earnings thereon, may be immediately applied by Secured Party to repay the Debt
in such order as Secured Party shall elect in its discretion. Secured Party
shall be entitled to require proof, as a condition to TSI making of any
withdrawal from the Insurance Proceeds Account, that the amount of such
withdrawal is being applied for the purposes permitted hereunder. Additionally,
any proceeds of the Insurance Proceeds Account may be made available and
advanced by Secured Party directly to TSI, or directly to suppliers,
manufacturers, contractors and other persons entitled to payment in accordance
with and subject to reasonable conditions to disbursements as Secured Party may
impose to assure that such replacement, repair or restoration of the relevant
Collateral is paid for and performed and that no Liens arise by reason thereof.

                  (h) No Inventory nor Equipment shall be located at any
location, other than the locations set forth on Schedule 1 attached hereto,
which has not been disclosed in writing to Secured Party in advance of such
Inventory or Equipment being located at such location and for which Financing
Statements, and landlord subordinations or warehousemens' agreements, as the
case may be, (if such locations are not owned by TSI) covering such portion of
the Inventory or Equipment, as the case may be, have not been executed and
delivered by TSI and filed for record with the appropriate Governmental
Authority necessary to perfect the Liens granted hereby.

                  (i) TSI agrees to defend the Collateral and its proceeds
against all claims and demands of any Person at any time claiming the
Collateral.

         4.2 If TSI fails to comply with any of its agreements, covenants or
obligations under this Agreement or any other Loan Document, after giving effect
to any applicable cure period, Secured Party (in TSI's name or in Secured
Party's own name) may perform them or cause them to be performed for the account
and at the expense of TSI, but shall have no obligation to perform any of them
or cause them to be performed. Any and all expenses thus incurred or paid by
Secured Party shall be TSI's obligations to Secured Party due and payable on
demand, or if no


SECURITY AGREEMENT (Personal Property) - Page 7

<PAGE>   8


demand is sooner made, then they shall be due on or before four (4) years after
the respective dates on which they were incurred, and each shall bear interest
from the date one (1) Business Day after Secured Party demands payment for such
amounts until the date TSI repays such amounts to Secured Party, at the Past Due
Rate. Upon making any such payment or incurring any such expense, Secured Party
shall be fully and automatically subrogated to all of the rights of the person,
corporation or body politic receiving such payment. Any amounts owing by TSI to
Secured Party pursuant to this or any other provision of this Agreement shall
automatically and without notice be and become a part of the Debt and shall be
secured by this and all other instruments securing the Debt. The amount and
nature of any such expense and the time when it was paid shall be fully
established by the affidavit of Secured Party or any of Secured Party's officers
or agents. The exercise of the privileges granted to Secured Party in this
Section shall in no event be considered or constitute a cure of the default or a
waiver of Secured Party's right at any time after an Event of Default to declare
the Debt to be at once due and payable, but is cumulative of such right and of
all other rights given by this Agreement, the Credit Agreement, the Notes and
the Loan Documents and of all rights given Secured Party by law.

                                    ARTICLE 5
                     ASSIGNMENT OF PAYMENTS; CERTAIN POWERS
                         OF SECURED PARTY; NO ASSUMPTION

         5.1 Upon the occurrence of an Event of Default and so long as it is
continuing and has not been expressly waived by Secured Party in writing,
Secured Party may request TSI to notify each account debtor and each other
Person (each a "Collateral Obligor") obligated to make payment in respect of any
of the Collateral of the Liens in such Collateral granted herein and instruct
such Collateral Obligor to pay over to Secured Party, all or any part of the
Collateral without making any inquiries as to the status or balance of TSI and
without any notice to or further consent of TSI. If TSI does not promptly comply
with such request, Secured Party may, but shall not be obligated to, directly
notify each such Collateral Obligor of the Liens in the Collateral granted
herein and instruct such Collateral Obligor to pay over to Secured Party, all or
any part of the Collateral without making any inquiries as to the status or
balance of TSI and without any notice to or further consent of TSI.

         5.2 The powers conferred on Secured Party pursuant to this Article 5
are conferred solely to protect Secured Party's interest in the Collateral and
shall not impose any duty or obligation on Secured Party to perform any of the
powers herein conferred. Additionally, the powers conferred on Secured Party
pursuant to this Article 5 are cumulative of all other similar, related or
additional powers conferred on Secured Party by the terms and provisions of
Section 9.21 of the Credit Agreement and are not intended to limit or restrict
in any manner whatsoever any of such powers and rights conferred on Secured
Party under the terms and provisions of the Credit Agreement or any other Loan
Documents. No exercise of any of such rights provided for in this Article 5 or
in the Credit Agreement shall constitute a retention of collateral in
satisfaction of the indebtedness as provided for in Section 9.505 of the Uniform
Commercial Code of Texas or the state or states where the applicable Collateral
is located.

                                EVENTS OF DEFAULT

         An Event of Default under the Credit Agreement shall constitute an
Event of Default (herein so called) under this Agreement.

                                    ARTICLE 7
                          REMEDIES IN EVENT OF DEFAULT

         7.1 In addition to the other rights and remedies provided for in the
Credit Agreement, upon the occurrence and during the continuation of an Event of
Default:

                  (a) Secured Party is authorized, in any legal manner and
without breach of the peace, to take possession of the Collateral (TSI HEREBY
WAIVES ALL CLAIMS FOR DAMAGES ARISING FROM OR CONNECTED WITH ANY SUCH TAKING,
EXCEPT AS MAY BE CAUSED BY THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SECURED
PARTY) and of all books, records and accounts relating thereto and to exercise
without interference from TSI any and all rights which TSI has with respect to
the management, possession, operation, protection, preservation, distribution or
resale of the Collateral, including the right to sell or rent the same for the
account of TSI and to deduct from such sale proceeds or such rents all costs,
expenses and liabilities of every character incurred by Secured Party in
collecting such sale proceeds or such rents, and in managing, operating,
maintaining, protecting or preserving the Collateral and to apply the remainder
of such sales proceeds or such rents on the Debt in such manner as Secured Party
may elect. Before any sale, Secured Party may, at its option, complete the
processing of any of the Collateral and/or repair or recondition the same to
such extent as Secured Party may deem advisable and any reasonable sums expended
therefor by Secured Party shall be reimbursed by TSI. Secured Party may take
possession of TSI's premises to complete such processing, repairing and/or
reconditioning, using the facilities and other property of TSI to do so, to
store any Collateral and to conduct any sale as provided for herein, all without
compensation to TSI. All costs, expenses, and liabilities incurred by Secured
Party in collecting such sales proceeds or such rents, or in managing,
operating, maintaining, protecting or preserving such properties, or in
processing, repairing and/or reconditioning the Collateral if not paid out of
such sales proceeds or such rents as hereinabove provided, shall constitute a
demand obligation owing by TSI and shall bear interest from the date of
expenditure until paid at the Past Due Rate, all of which shall constitute a
portion of the Debt. If necessary to obtain the possession provided for above,
Secured Party may invoke any and all legal remedies to dispossess TSI, including
specifically one or more actions for forcible entry and detainer. In connection
with any action taken by Secured Party pursuant to this paragraph, Secured Party
shall not be liable for any loss sustained by TSI resulting from any failure to
sell or let the Collateral, or any part thereof, or from any other act or
omission of Secured Party with respect to the Collateral unless such loss is
caused by the gross negligence or willful misconduct of Secured Party, nor shall
Secured Party be obligated to perform or discharge any obligation, duty, or
liability under any sale or lease agreement covering the Collateral or any part
thereof or under or by reason of this instrument or the exercise of rights or
remedies hereunder.

                  (b) Secured Party may, without notice except as hereinafter
provided, sell the Collateral or any part thereof at public or private sale
(with or without appraisal or having the Collateral at the place of sale) for
cash, upon credit, or for future delivery, and at such price or

SECURITY AGREEMENT (Personal Property) - Page 9

<PAGE>   10


prices as Secured Party may deem best, and Secured Party may be the purchaser of
any and all of the Collateral so sold and may apply upon the purchase price
therefor any of the Debt and thereafter hold the same absolutely free from any
right or claim of whatsoever kind. In any such public or private sale, Secured
Party may (but shall not be obligated to) submit a bid in the form of a credit
against the Debt owed to Secured Party, and Secured Party or its designee may
accept title to property purchased at such public or private sale. Upon any such
sale Secured Party shall have the right to deliver, assign and transfer to the
purchaser thereof the Collateral so sold. Each purchaser at any such sale shall
hold the property sold absolutely free from any claim or right of whatsoever
kind, including any equity or right of redemption, stay or appraisal which TSI
has or may have under any rule of law or statute now existing or hereafter
adopted. To the extent notice is required by applicable law, Secured Party shall
give TSI written notice at the address set forth herein (which shall satisfy any
requirement of notice or reasonable notice in any applicable statute) of Secured
Party's intention to make any such public or private sale. Such notice (if any
is required by applicable law) shall be personally delivered or mailed, postage
prepaid, at least ten (10) calendar days before the date fixed for a public
sale, or at least (10) calendar days before the date after which the private
sale or other disposition is to be made, unless the Collateral is of a type
customarily sold on a recognized market, is perishable or threatens to decline
speedily in value. Such notice (if any is required by applicable law), in case
of public sale, shall state the time and place fixed for such sale or, in case
of private sale or other disposition other than a public sale, the time after
which the private sale or other such disposition is to be made. Any public sale
shall be held at such time or times, within the ordinary business hours and at
such place or places, as Secured Party may fix in the notice of such sale. At
any sale, the Collateral may be sold in one lot as an entirety or in separate
parcels as Secured Party may determine. Secured Party shall not be obligated to
make any sale pursuant to any such notice. Secured Party may, without notice or
publication, adjourn any public or private sale or cause the same to be
adjourned from time to time by announcement at any time and place fixed for the
sale, and such sale may be made at any time or place to which the same may be so
adjourned. In case of any sale of all or any part of the Collateral on credit or
for future delivery, the Collateral so sold may be retained by Secured Party
until the selling price is paid by the purchaser thereof, but Secured Party
shall not incur liability in case of the failure of such purchaser to take up
and pay for the Collateral so sold, and in case of any such failure, such
Collateral may again be sold upon like notice. Each and every method of
disposition described in this Section shall constitute disposition in a
commercially reasonable manner. Each Obligor, to the extent applicable, shall
remain liable for any deficiency.

                  (c) Secured Party shall have all the rights of a secured party
after default under the Uniform Commercial Code of the state or states where the
applicable Collateral is situated, and in conjunction with, in addition to or in
substitution for those rights and remedies:

                           (i) Secured Party may require TSI to assemble the
         Collateral and make it available at a place Secured Party designates
         which is mutually convenient to allow Secured Party to take possession
         or dispose of the Collateral; and

                           (ii) it shall not be necessary that Secured Party
         take possession of the Collateral or any part thereof before the time
         that any sale pursuant to the provisions of


SECURITY AGREEMENT (Personal Property) - Page 10

<PAGE>   11


         this Article is conducted and it shall not be necessary that the
         Collateral or any part thereof be present at the location of such sale;
         and

                           (iii) before application of proceeds of disposition
         of the Collateral to the Debt, such proceeds shall be applied to the
         reasonable expenses of retaking, holding, preparing for sale or lease,
         selling, leasing, licensing, sublicensing and the like, as well as
         reasonable attorneys' fees and legal expenses incurred by Secured
         Party, each Obligor, to the extent applicable, to remain liable for any
         deficiency; and

                           (iv) the sale by Secured Party of less than the whole
         of the Collateral shall not exhaust the rights of Secured Party
         hereunder, and Secured Party is specifically empowered to make
         successive sale or sales hereunder until the whole of the Collateral
         shall be sold; and, if the proceeds of such sale of less than the whole
         of the Collateral shall be less than the aggregate of the Debt, this
         Agreement and the security interest created hereby shall remain in full
         force and effect as to the unsold portion of the Collateral just as
         though no sale had been made; and

                           (v) in the event any sale hereunder is not completed
         or is defective in the reasonable opinion of Secured Party, such sale
         shall not exhaust the rights of Secured Party hereunder and Secured
         Party shall have the right to cause a subsequent sale or sales to be
         made hereunder; and

                           (vi) any and all statements of fact made in any bill
         of sale or assignment or other instrument evidencing any foreclosure
         sale hereunder shall be taken as rebuttable evidence of the truth of
         the facts so stated; and

                           (vii) Secured Party may appoint or delegate any one
         or more persons as agent to perform any act or acts necessary or
         incident to any sale held by Secured Party, including the sending of
         notices and the conduct of sale, but in the name and on behalf of
         Secured Party; and

                           (viii) demand of performance, advertisement and
         presence of property at sale are hereby WAIVED and Secured Party is
         hereby authorized to sell hereunder any evidence of debt it may hold as
         security for the Debt. Except as provided herein or in any other Loan
         Document, all demands and presentments of any kind or nature are
         expressly WAIVED by TSI. TSI WAIVES the right to require Secured Party
         to pursue any other remedy for the benefit of TSI and agrees that
         Secured Party may proceed against any Obligor for the amount of the
         Debt owed to Secured Party without taking any action against any other
         Obligor or any other person or entity and without selling or otherwise
         proceeding against or applying any of the Collateral in Secured Party's
         possession.

                  (d) Secured Party may apply to a court of competent
jurisdiction for the appointment of a receiver, or a receiver and manager, over
TSI, or any or all of the Collateral, with such duties, powers and obligations
as the court making such appointment shall confirm,


SECURITY AGREEMENT (Personal Property) - Page 11

<PAGE>   12


and TSI hereby irrevocably consents to the appointment of such receiver or such
receiver and manager.

         7.2 All remedies expressly provided for in the Agreement are cumulative
of any and all other remedies existing at law or in equity and are cumulative of
any and all other remedies provided for in any other instrument securing the
payment of the Debt, or any part thereof, or otherwise benefiting Secured Party,
and the resort to any remedy provided for hereunder or under any such other
instrument or provided for by law shall not prevent the concurrent or subsequent
employment of any other appropriate remedy or remedies.

         7.3 Secured Party may resort to any security given by this Agreement or
to any other security now existing or hereafter given to secure the payment of
the Debt, in whole or in part, and in such portions and in such order as may
seem best to Secured Party in its sole and uncontrolled discretion, and any such
action shall not in anywise be considered as a waiver of any of the rights,
benefits or security interests evidenced by this Agreement.

         7.4 To the full extent TSI may do so, TSI agrees that TSI will not at
any time insist upon, plead, claim or take the benefit or advantage of any law
now or hereafter in force providing for any appraisement, valuation, stay,
extension or redemption, and TSI, for TSI, TSI's successors, receivers, trustees
and assigns, and for any and all persons ever claiming any interest in the
Collateral, to the extent permitted by law, hereby WAIVE and release all rights
of redemption, valuation, appraisement, stay of execution, notice of intention
to mature or to declare due the whole of the Debt, notice of election to mature
or to declare due the whole of the Debt and all rights to a marshaling of the
assets of TSI, including the Collateral, or to a sale in inverse order of
alienation in the event of foreclosure of the security interest hereby created.

                                    ARTICLE 8
                              ADDITIONAL AGREEMENTS

         8.1 Subject to the automatic reinstatement provisions of Section 8.21
below, upon full satisfaction of the Debt, complete performance of all of the
obligations of the Obligors under the Loan Documents and final termination of
Secured Party's obligations, if any, to make any further advances under any Note
or to provide any other financial accommodations to any Obligor, all rights
under this Agreement shall terminate and the Collateral shall become wholly
clear of the security interest evidenced hereby, and upon written request by TSI
such security interest shall be released by Secured Party in due form and at
TSI's cost.

         8.2 Secured Party may waive any default without waiving any other prior
or subsequent default. Secured Party may remedy any default without waiving the
default remedied. The failure by Secured Party to exercise any right, power or
remedy upon any default shall not be construed as a waiver of such default or as
a waiver of the right to exercise any such right, power or remedy at a later
date. No single or partial exercise by Secured Party of any right, power or
remedy hereunder shall exhaust the same or shall preclude any other or further
exercise thereof, and every such right, power or remedy hereunder may be
exercised at any time and from time to time. No modification or waiver of any
provision hereof nor consent to any departure by TSI therefrom shall in any
event be effective unless the same shall be in writing and


SECURITY AGREEMENT (Personal Property) - Page 12

<PAGE>   13


signed by Secured Party, and then such waiver or consent shall be effective only
in the specific instances, for the purpose for which given and to the extent
therein specified. No notice to nor demand on TSI in any case shall of itself
entitle TSI to any other or further notice or demand in similar or other
circumstances. Acceptance by Secured Party of any payment in an amount less than
the amount then due on the Debt shall be deemed an acceptance on account only
and shall not in any way affect the existence of a default hereunder.

         8.3 Subject to Section 9.11 of the Credit Agreement, Secured Party may
at any time and from time to time in writing (a) waive compliance by TSI with
any covenant herein made by TSI to the extent and in the manner specified in
such writing; (b) consent to TSI's doing any act which hereunder TSI is
prohibited from doing, or consent to TSI's failing to do any act which hereunder
TSI is required to do, to the extent and in the manner specified in such
writing; (c) release any part of the Collateral, or any interest therein, from
the security interest of this Agreement; or (d) release any Person liable,
either directly or indirectly, for the Debt or for any covenant herein or in any
other instrument now or hereafter securing the payment of the Debt, without
impairing or releasing the liability of any other Person. No such act shall in
any way impair the rights of Secured Party hereunder except to the extent
specifically agreed to by Secured Party in such writing.

         8.4 Secured Party shall not be required to take any steps necessary to
preserve any rights against prior parties to any of the Collateral.

         8.5 The Liens and other rights of Secured Party hereunder shall not be
impaired by any indulgence, moratorium or release granted by Secured Party,
including but not limited to (a) any renewal, extension or modification which
Secured Party may grant with respect to the Debt; (b) any surrender compromise,
release, renewal, extension, exchange or substitution which Secured Party may
grant in respect of any item of the Collateral, or any part thereof or any
interest therein; or (c) any release or indulgence granted to any endorser,
guarantor or surety of the Debt.

         8.6 A carbon, photographic or other reproduction of this Agreement or
of any financing statement relating to this Agreement shall be sufficient as a
financing statement. TSI will cause all financing statements and continuation
statements relating hereto to be recorded, filed, re-recorded and refiled in
such manner and in such places as Secured Party shall reasonably request and
will pay all such recording, filing, re-recording, and refiling taxes, fees and
other charges.

         8.7 This Agreement may be executed in several identical counterparts
and by the parties hereto on separate counterparts, and each counterpart, when
so executed and delivered, shall constitute an original instrument, and all such
separate counterparts shall constitute but one and the same instrument.

         8.8 In the event the ownership of the Collateral or any part thereof
becomes vested in a Person other than TSI, Secured Party may, without notice to
TSI deal with such successor or successors in interest with reference to this
Agreement and to the Debt in the same manner as with TSI, without in any way
vitiating or discharging TSI's liability hereunder or upon the Debt.


SECURITY AGREEMENT (Personal Property) - Page 13

<PAGE>   14


No sale of the Collateral, and no forbearance on the part of Secured Party and
no extension of the time for the payment of the Debt given by Secured Party
shall operate to release, discharge, modify, change or affect, in whole or in
part, the liability of TSI hereunder for the payment of the Debt or the
liability of any other person hereunder for the payment of the Debt, except as
agreed to in writing by Secured Party or as expressly provided in the Credit
Agreement.

         8.9 Any other or additional security taken for the payment of any of
the Debt shall not in any manner affect the security given by this Agreement.

         8.10 To the extent that proceeds of the Debt are used to pay
indebtedness secured by any outstanding Lien against the Collateral, such
proceeds have been advanced by Secured Party at TSI's request, and Secured Party
shall be subrogated to any and all Liens owned by any owner or holder of such
outstanding Lien, irrespective of whether said Lien is released.

         8.11 If any part of the Debt cannot be lawfully secured by this
Agreement, or if the Liens of this Agreement cannot be lawfully enforced to pay
any part of the Debt, then and in either such event, at the option of Secured
Party, all payments on the Debt shall be deemed to have been first applied
against that part of the Debt.

         8.12 Subject to Section 9.11 of the Credit Agreement, this Agreement
shall not be changed orally but shall be changed only by agreement in writing
signed by TSI and Secured Party. No course of dealing between the parties, no
usage of trade and no parole or extrinsic evidence of any nature shall be used
to supplement or modify any of the terms or provisions of this Agreement.

         8.13 Any notice, request or other communication required or permitted
to be given hereunder shall be given as provided in the Credit Agreement.

         8.14 This Agreement shall be binding upon TSI, and the trustees,
receivers, successors and assigns of TSI, including all successors in interest
of TSI in and to all or any part of the Collateral, and shall benefit Secured
Party and its successors and assigns.

         8.15 If any provision of this Agreement is held to be illegal, invalid
or unenforceable under present or future laws, the legality, validity and
enforceability of the remaining provisions of this Agreement shall not be
affected thereby, and this Agreement shall be liberally construed so as to carry
out the intent of the parties to it. Each waiver in this Agreement is subject to
the overriding and controlling rule that it shall be effective only if and to
the extent that (a) it is not prohibited by applicable law and (b) applicable
law neither provides for nor allows any material sanctions to be imposed against
Secured Party for having bargained for and obtained it.

         8.16 Secured Party shall be deemed to have exercised reasonable care in
the custody and preservation of any of the Collateral in its possession if it
takes such action for that purpose as TSI requests in writing, but failure of
Secured Party to comply with such request shall not of itself be deemed a
failure to have exercised reasonable care, and no failure of Secured Party to
take any action so requested by TSI shall be deemed a failure to exercise
reasonable care in the custody or preservation of such Collateral. Secured Party
shall not be responsible in any way for


SECURITY AGREEMENT (Personal Property) - Page 14

<PAGE>   15


any depreciation in the value of the Collateral, nor shall any duty or
responsibility whatsoever rest upon Secured Party to take any steps to preserve
rights against prior parties or to enforce collection of the Collateral by legal
proceedings or otherwise, the sole duty of Secured Party, its successors and
assigns, being to receive collections, remittances and payments on such
Collateral as and when made and received by Secured Party and, as provided by
the Credit Agreement, to apply the amount or amounts so received, after
deduction of any collection costs incurred, as payment upon any of the Debt or
to hold the same for the account and order of TSI.

         8.17 In the event TSI instructs Secured Party, in writing or orally, to
deliver any or all of the Collateral to a third Person, and Secured Party agrees
to do so, the following conditions shall be conclusively deemed to be a part of
Secured Party's agreement, whether or not they are specifically mentioned to TSI
at the time of such agreement: (i) Secured Party shall not assume any
responsibility for checking the genuineness or authenticity of any Person
purporting to be a messenger, employee or representative of such third Person to
whom TSI has directed Secured Party to deliver the Collateral, or the
genuineness or authenticity of any document of instructions delivered by such
Person; (ii) TSI will be considered by requesting any such delivery to have
assumed all risk of loss as to the Collateral; (iii) Secured Party's sole
responsibility will be to deliver the Collateral to the Person purporting to be
such third Person described by TSI, or a messenger, employee or representative
thereof; and (iv) Secured Party and TSI hereby expressly agree that the
foregoing actions by Secured Party shall constitute reasonable care.

         8.18 The pronouns used in this Agreement are in the masculine and
neuter genders but shall be construed as feminine, masculine or neuter as
occasion may request. "Secured Party", "Obligor" and "TSI" as used in this
Agreement include the heirs, devisees, successors, administrators, personal
representatives, trustees, beneficiaries, conservators, receivers, and
successors and assigns of those parties.

         8.19 The section headings appearing in this Agreement have been
inserted for convenience only and shall be given no substantive meaning or
significance whatever in construing the terms and provisions of this Agreement.
Terms used in this Agreement which are defined in the Texas Uniform Commercial
Code are used with the meanings as therein defined. Wherever the term
"including" or a similar term is used in this Agreement, it shall be read as if
it were written "including by way of example only and without in any way
limiting the generality of the clause or concept referred to."

         8.20 THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE APPLICABLE LAWS OF THE STATE OF TEXAS (OTHER THAN THE CONFLICTS OF LAWS
PRINCIPLES THEREOF) AND THE UNITED STATES OF AMERICA FROM TIME TO TIME IN
EFFECT.

         8.21 TSI agrees that, if at any time all or any part of any payment
previously applied by Secured Party to the Debt is or must be returned by
Secured Party, or recovered from Secured Party, for any reason (including the
order of any bankruptcy court), this Agreement shall automatically be reinstated
to the same effect, as if the prior application had not been made, and, in
addition, TSI hereby agrees to indemnify Secured Party against, and to save and
hold Secured Party harmless from any required return by Secured Party, or
recovery from Secured Party, of


SECURITY AGREEMENT (Personal Property) - Page 15

any such payments because of its being deemed preferential under applicable
bankruptcy, receivership or insolvency laws, or for any other reason.

         8.22 Secured Party may from time to time and at any time, without any
necessity for any notice to or consent by TSI or any other Person, release all
or any part of the Collateral from the security interests of this Agreement,
with or without cause, including as a result of any determination by Secured
Party that the Collateral or any portion thereof contains or has been
contaminated by or releases or discharges any hazardous or toxic waste, material
or substance.

         8.23 THIS AGREEMENT REPRESENTS 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.

                        UNCONDITIONAL GUARANTY AGREEMENT


     THIS UNCONDITIONAL GUARANTY AGREEMENT (this "Guaranty") is executed as of
April 1, 1999, by TIDEL TECHNOLOGIES, INC., a Delaware corporation,
("Guarantor"), for the benefit of CHASE BANK OF TEXAS, N.A. ("Bank").


                                    RECITALS

     1. Pursuant to that certain Credit Agreement (as the same may be amended,
modified, increased, supplemented and/or restated from time to time, the "Loan
Agreement"), dated as of the date hereof and executed by and among Tidel
Engineering, L.P. ("Borrower") Bank and Guarantor, the Bank has agreed to make
certain loans to Borrower in the principal amount set forth therein;

     2. The Bank is willing to make certain loans under the Loan Agreement but
only on the condition, among others, that Guarantor shall have executed and
delivered to Bank, for its benefit, this Guaranty; and

     3. Guarantor will derive substantial direct and indirect benefit from the
making of the loans under the Loan Agreement.

     NOW, THEREFORE, as an inducement to Bank to make certain loans to Borrower,
and to extend such additional credit as Bank may from time to time agree to
extend, and for other good and valuable consideration, the receipt and legal
sufficiency of which are hereby acknowledged, Guarantor, jointly and severally,
hereby agrees as follows:


                                   AGREEMENTS

                                    ARTICLE I

                          NATURE AND SCOPE OF GUARANTY

     Section 1.01. Guaranty of Obligations. Guarantor hereby irrevocably and
unconditionally guarantees to Bank and its successors and assigns the due and
punctual payment of the Obligations (hereinafter defined). Guarantor hereby
irrevocably and unconditionally covenants and agrees that it is liable for the
Obligations as primary obligor.

     Section 1.02. Definition of Obligations. As used herein, the term
"Obligations" means:

             (a) All indebtedness, liabilities, obligations and duties evidenced
by the Revolving Note (as such term is defined in the Loan Agreement), whether
or not Borrower has any recourse liability therefor to Bank and whether or not
the Revolving Note is enforceable against Borrower or any other party liable
thereon;


UNCONDITIONAL GUARANTY AGREEMENT - Page 1
(Tidel Technologies, Inc.)


<PAGE>   2



             (b) Any and all other indebtedness, liabilities, obligations and
duties of every kind and character of Borrower to Bank arising pursuant to or
related to the Loan Agreement, the Revolving Note, or any loan agreement,
security agreement, collateral document or other document, instrument or
contract executed in connection with the Loan Agreement whether now or hereafter
existing or arising, (but expressly excluding the Term Note (as defined in the
Loan Agreement)) regardless of whether such present or future indebtedness,
liabilities, obligations or duties be direct or indirect, primary or secondary,
joint, several, or joint and several, fixed or contingent, and regardless of
whether such present or future indebtedness, liabilities, obligations or duties
may, prior to their acquisition by Bank, be or have been payable to, or be or
have been in favor of, some other person or have been acquired by Bank in any
transaction with one other than Borrower including further, without limitation,
the "Obligations" as defined in the Loan Agreement (but expressly excluding the
Term Note);

             (c) Any and all renewals, extensions, modifications and increases
of such indebtedness, liabilities, obligations and duties, or any part thereof,
described in items (a) and (b) of this SECTION 1.02; and

             (d) All costs, expenses and fees, including but not limited to
court costs and attorneys' fees, arising in connection with the collection of
any or all amounts, indebtedness, obligations and liabilities of Borrower to
Bank described in items (a) through (c) of this SECTION 1.02 including costs,
expenses and fees arising in connection with the enforcement of this Guaranty.

     Section 1.03. Obligations Not Reduced by Offset. The Obligations, and the
liabilities and obligations of Guarantor to Bank hereunder, shall not be
reduced, discharged or released because or by reason of any existing or future
offset, claim or defense of Borrower, or any other party, against Bank or
against payment of the Obligations, whether such offset, claim or defense arises
in connection with the Obligations (or the transactions creating the
Obligations) or otherwise. Without limiting the foregoing or the Guarantor's
liability hereunder, to the extent that Bank advances funds or extends credit to
Borrower, and does not receive payments or benefits thereon in the amounts and
at the times required or provided by applicable agreements or laws, Guarantor is
absolutely liable to make such payments to (and confer such benefits on) Bank,
on a timely basis.

     Section 1.04. "Borrower" to Include Successors. The term "Borrower" as used
herein shall include any new or successor entity formed as a result of any
merger or reorganization of Borrower, and all other successors and assigns of
Borrower.

     Section 1.05. Payment by Guarantor. The Guarantor shall have the same
rights as Borrower under the Loan Agreement to cure any Event of Default (as
defined in the Loan Agreement) within the time periods, and otherwise in
accordance with the terms, provided in the Loan Agreement. If all or any part of
the Obligations shall not be punctually paid when due, whether at maturity or
earlier by acceleration or otherwise, Guarantor shall, immediately upon demand
by Bank, and without presentment, protest, notice of protest, notice of
non-payment, notice of intention to accelerate or acceleration or any other
notice whatsoever, pay in lawful

money of the United States of America, the amount due on the Obligations to Bank
at Bank's principal office in Dallas, Texas. Such demand(s) may be made at any
time coincident with or after the time for payment of all or part of the
Obligations, and may be made from time to time with respect to the same or
different items of Obligations. Such demand shall be deemed made, given and
received in accordance with SECTION 5.02 hereof.

     Section 1.06. No Duty to Pursue Others. It shall not be necessary for Bank
(and Guarantor hereby waives any rights which Guarantor may have to require
Bank), in order to enforce such payment by Guarantor, first to (a) institute
suit or exhaust its remedies against Borrower or others liable on the
Obligations or any other person, (b) enforce Bank's rights against any security
which shall ever have been given to secure the Obligations, (c) enforce Bank's
rights against any other guarantors of the Obligations, (d) join Borrower or any
others liable on the Obligations in any action seeking to enforce this Guaranty,
(e) exhaust any remedies available to Bank against any security which shall ever
have been given to secure the Obligations, or (f) resort to any other means of
obtaining payment of the Obligations. Guarantor hereby waives any other rights
of Guarantor provided by Tex. Bus. Comm. Code Ann. Art. 34. Bank shall not be
required to mitigate damages or take any other action to reduce, collect or
enforce the Obligations.

     Section 1.07. Waiver of Notices, etc. Guarantor hereby waives notice of (a)
any loans or advances made by Bank to Borrower, (b) acceptance of this Guaranty,
(c) any amendment or extension of the Loan Agreement, the Revolving Note or of
any other instrument or document pertaining to all or any part of the
Obligations, (d) the execution and delivery by Borrower and Bank of the Loan
Agreement or of Borrower's execution and delivery of any promissory notes or
other documents in connection therewith, (e) Bank's transfer or disposition of
the Obligations, or any part thereof, (f) protest, proof of non-payment or
default by Borrower, or (g) any other action at any time taken or omitted by
Bank, and, generally, all demands and notices of every kind in connection with
this Guaranty, or any documents or agreements evidencing, securing or relating
to any of the Obligations, except as otherwise specifically provided herein.

     Section 1.08. Nature of Guaranty. This Guaranty is an irrevocable,
absolute, continuing guaranty of payment and performance and not a guaranty of
collection. This Guaranty shall continue to be effective with respect to any
Obligations existing or which arise out of commitments made by Bank prior to any
attempted revocation by Guarantor, and as to all renewals and extensions
thereof, in whole or in part, whenever made. The fact that at any time or from
time to time the Obligations may be increased or reduced shall not release,
discharge or reduce the obligation of Guarantor with respect to indebtedness or
obligations of Borrower to Bank thereafter incurred (or other Obligations
thereafter arising). This Guaranty may be enforced by Bank and any subsequent
holder of the Obligations and shall not be discharged by the assignment or
negotiation of all or part of the Obligations.

     Section 1.09. Payment of Expenses. In the event that Guarantor should
breach or fail to timely perform any provisions of this Guaranty, Guarantor
shall, immediately upon demand by Bank, pay Bank all costs and expenses
(including court costs and reasonable attorneys' fees) incurred by Bank in the
enforcement hereof or the preservation of Bank's rights hereunder. The covenant
contained in this SECTION 1.09 shall survive the payment of the Obligations.

     Section 1.10. Effect of Bankruptcy. In the event that, pursuant to any
insolvency, bankruptcy, reorganization, receivership or other debtor relief law,
or any judgment, order or decision thereunder, Bank must rescind or restore any
payment, or any part thereof, received by Bank in satisfaction of the
Obligations, any prior release or discharge from the terms of this Guaranty
given to Guarantor by Bank shall be without effect, and this Guaranty shall
remain in full force and effect. It is the intention of Guarantor that
Guarantor's obligations hereunder shall not be discharged except by Guarantor's
performance of such obligations and then only to the extent of such performance.


                                   ARTICLE II

              EVENTS AND CIRCUMSTANCES NOT REDUCING OR DISCHARGING

officers or representatives executing the documents creating the Obligations
acted in excess of their authority, (d) the Obligations violate applicable usury

it being recognized, acknowledged and agreed by Guarantor that Guarantor may be

contingent, primary, secondary, several, joint and several, or otherwise, and
irrespective of whether such debts or liabilities be evidenced by note,
contract, open account, or otherwise, and irrespective of the person or persons
in whose favor such debts or liabilities may, at their inception, have been, or
may hereafter be created, or the manner in which they have been or may hereafter
be acquired by Guarantor. Except as otherwise allowed under the Loan Agreement,
until the Obligations shall be paid and satisfied in full, and in cash as to
monetary Obligations, and Guarantor shall have performed all of its obligations
hereunder, Guarantor shall not receive or collect, directly or indirectly, from
Borrower or any other party any amount upon the Guarantor Claims.

                 (a) Any and all rights that would result in Guarantor being
         deemed a "creditor", under the United States Bankruptcy Code, of
         Borrower or any other person, on account of payments made or
         obligations performed by Guarantor relating to this Guaranty; and

                 (b) Any claim, right or remedy which Guarantor may now have or

         limitation, any claim, remedy or right of subrogation, reimbursement,
         exoneration, contribution, indemnification, or participation in any
         claim, right or remedy of Bank against Borrower or any security which
         now has or hereafter acquires, whether or not such claim, right or
         remedy arises in equity under contract, by statute, under common law or
         otherwise.

         Section 4.03. Claims in Bankruptcy. In the event of receivership,
bankruptcy, reorganization, arrangement, debtor's relief, or other insolvency
proceedings involving Borrower as debtor, Bank shall have the right to prove
their claims in any such proceeding so as to establish their rights hereunder
and receive directly from the receiver, trustee or other court custodian
dividends and payments which would otherwise be payable upon Guarantor Claims.
Guarantor hereby assigns such dividends and payments to Bank.

         Section 4.04. Payments Held in Trust. In the event that,
notwithstanding SECTIONS 4.01, 4.02 and 4.03 above, Guarantor should receive any
funds, payment, claim or distribution which is prohibited by such Sections,
Guarantor agrees to hold in trust for Bank an amount equal to the amount of all
funds, payments, claims or distributions so received, and agrees that it shall
have absolutely no dominion over the amount of such funds, payments, claims or
distributions, except to pay them promptly to Bank, and Guarantor covenants
promptly to pay the same to Bank.

         Section 4.05. Liens Subordinate. Guarantor agrees that any liens,
security interests, judgment liens, charges or other encumbrances upon
Borrower's assets securing payment of the Guarantor Claims shall be and remain
inferior and subordinate to any liens, security interests, judgment liens,
charges or other encumbrances upon Borrower's assets securing payment of the
Obligations, regardless of whether such encumbrances in favor of Guarantor or
Bank presently exist or are hereafter created or attached. Without the prior
written consent of Bank, Guarantor shall not (a) exercise or enforce any
creditor's right it may have against Borrower, or (b) foreclose, repossess,
sequester or otherwise take steps or institute any action or proceedings
(judicial or otherwise, including without limitation the commencement of, or
joinder in, any liquidation, bankruptcy, rearrangement, debtor's relief or
insolvency proceeding) to enforce any liens, mortgages, deeds of trust, security
interest, collateral rights, judgments or other encumbrances on assets of
Borrower held by Guarantor.

         Section 4.06. Notation of Records. All promissory notes, accounts
receivable ledgers or other evidences of the Guarantor Claims accepted by or
held by Guarantor shall contain a specific written notice thereon that the
indebtedness evidenced thereby is subordinated under the terms of this Guaranty.

         Section 4.07. Disgorged Payments. If after receipt of any payment of
all or any part of the Obligations, Bank is for any reason compelled to
surrender such payment to any person or

entity because such payment is determined to be void or voidable as a
preference, impermissible setoff, or a diversion of trust funds, or for any
reason, this Guaranty shall continue in full force notwithstanding any contrary
action which may have been taken by Bank in reliance upon such payment, and any
such contrary action so taken shall be without prejudice to Bank's rights under
this Guaranty and shall be deemed to have been conditioned upon such payment
having become final and irrevocable.


                                    ARTICLE V

                                  MISCELLANEOUS

         Section 5.01. Waiver. No failure to exercise, and no delay in
exercising, on the part of Bank, any right hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise thereof preclude any other or
further exercise thereof or the exercise of any other right. The rights of Bank
hereunder shall be in addition to all other rights provided by law. No
modification or waiver of any provision of this Guaranty, nor consent to
departure therefrom, shall be effective unless in writing and signed by Bank and
no such consent or waiver shall extend beyond the particular case and purpose
involved. No notice or demand given in any case shall constitute a waiver of the
right to take other action in the same, similar or other instances without such
notice or demand.

         Section 5.02. Notices. Any notices or other communications required or
permitted to be given by this Guaranty must be given in writing and in the
manner and at the addresses set forth in the Loan Agreement, or at such other
address as Guarantor or the Bank shall so designate in writing.

         Section 5.03. Usury Compliance. It is the intention of Borrower,
Guarantor and Bank to conform strictly to applicable usury laws. Accordingly, no
agreements, conditions, provisions or stipulations contained in this Guaranty or
any other instrument, document or agreement between Guarantor or Borrower and
Bank or default of Guarantor or Borrower, or the exercise by Bank of the right
to accelerate the payment of the maturity of principal and interest, or to
exercise any option whatsoever contained in this Guaranty or any other agreement
between Guarantor or Borrower and Bank, or the arising of any contingency
whatsoever, shall entitle Bank to collect, in any event, interest exceeding the
maximum rate of interest permitted by applicable state or federal law in effect
from time to time hereafter (the "Maximum Legal Rate") and in no event shall
Guarantor be obligated to pay interest exceeding such Maximum Legal Rate and all
agreements, conditions or stipulations, if any, which may in any event or
contingency whatsoever operate to bind, obligate or compel Guarantor to pay a
rate of interest exceeding the Maximum Legal Rate, shall be without binding
force or effect, at law or in equity, to the extent only of the excess of
interest over such Maximum Legal Rate. In the event any interest is charged in
excess of the Maximum Legal Rate ("Excess"), Guarantor acknowledges and
stipulates that any such charge shall be the result of an accident and bona fide
error, and such Excess shall be, first, applied to reduce the principal then
unpaid hereunder; second, applied to reduce the Obligations; and third, returned
to Guarantor, it being the intention of the parties hereto not to enter at any
time into a usurious or otherwise illegal relationship. Guarantor

recognizes that, with fluctuations in the applicable rate on the Obligations and
the Maximum Legal Rate, such an unintentional result could inadvertently occur.
By the execution of this Guaranty, Guarantor covenants that the credit or return
of any Excess shall constitute the acceptance by Guarantor of such Excess.

         Section 5.04. Choice of Law; Forum Selection. This Agreement and the
other Loan Documents are being executed and delivered, and are intended to be
performed in the State of Texas. Except to the extent that the laws of the
United States may apply to the terms of this Agreement or any other Loan
Document, the substantive laws of the State of Texas shall govern the validity,
construction, enforcement and interpretation of this Guaranty. In the event of a
dispute involving this Guaranty, Guarantor irrevocably agrees that venue for
such dispute shall lie in any court of competent jurisdiction in Dallas County,
Texas.

         Section 5.05. Invalid Provisions. In the case any one or more of the
provisions contained in this Guaranty should be invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained therein shall not in any way be affected thereby,
unless such continued effectiveness of this Guaranty, as modified, would be
contrary to the basic understandings and intentions of the parties as expressed
herein.

         Section 5.06. Parties Bound. This Guaranty shall be binding upon and
inure to the benefit of the parties hereto and their respective successors,
assigns and legal representatives; provided, however, that Guarantor may not,
without the prior written consent of Bank, assign any of its rights, powers,
duties or obligations hereunder.

         Section 5.07. Headings. Section headings are for convenience of
reference only and shall in no way affect the interpretation of this Guaranty.

         Section 5.08. Multiple Counterparts. This Guaranty may be executed in
multiple counterparts, all of which taken together shall constitute one and the
same agreement, and any of the parties hereto may execute this Guaranty by
signing any counterpart.

         Section 5.09. Rights and Remedies. If Guarantor becomes liable for any
indebtedness owing by Borrower to Bank, by endorsement or otherwise, other than
under this Guaranty, such liability shall not be in any manner impaired or
affected hereby and the rights of Bank hereunder shall be cumulative of any and
all other rights that Bank may ever have against Guarantor. The exercise by Bank
of any right or remedy hereunder or under any other instrument, or at law or in
equity, shall not preclude the concurrent or subsequent exercise of any other
right or remedy.

         SECTION 5.10. INDEMNITY. GUARANTOR HEREBY AGREES TO INDEMNIFY, HOLD
HARMLESS, AND DEFEND BANK AND ITS DIRECTORS, OFFICERS, AGENTS, COUNSEL AND
EMPLOYEES ("INDEMNIFIED PERSONS") FROM AND AGAINST ANY AND ALL LOSSES,
LIABILITIES, DAMAGES, COSTS, EXPENSES, SUITS, ACTIONS AND PROCEEDINGS ("LOSSES")
EVER SUFFERED OR INCURRED BY ANY INDEMNIFIED PERSON ARISING OUT OF OR RELATING
TO THIS GUARANTY, ANY OTHER LOAN DOCUMENT OR ANY OTHER TRANSACTION CONTEMPLATED
HEREBY AND THEREBY, INCLUDING,


UNCONDITIONAL GUARANTY AGREEMENT - Page 10

WITHOUT LIMITATION, ANY LOSSES CAUSED BY THE NEGLIGENCE OF SUCH INDEMNIFIED
PERSON, BUT NOT INCLUDING ANY LOSSES CAUSED BY THE GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT OF SUCH INDEMNIFIED PERSON OR THE DEFAULT BY SUCH INDEMNIFIED PERSON
OF SUCH INDEMNIFIED PERSON'S OBLIGATIONS UNDER ANY LOAN DOCUMENT, AND GUARANTOR
SHALL REIMBURSE BANK AND EACH OTHER INDEMNIFIED PERSON FOR ANY EXPENSES
(INCLUDING IN CONNECTION WITH THE INVESTIGATION OF, PREPARATION FOR OR DEFENSE
OF ANY ACTUAL OR THREATENED CLAIM, ACTION OR PROCEEDING ARISING HEREFROM AND
THEREFROM, INCLUDING ANY SUCH COSTS OF RESPONDING TO DISCOVERY REQUESTS OR
SUBPOENAS, REGARDLESS OF WHETHER BANK OR SUCH OTHER INDEMNIFIED PERSON IS A
PARTY THERETO). WITHOUT LIMITING THE GENERALITY OF THE FOREGOING, THIS INDEMNITY
SHALL EXTEND TO ANY CLAIMS ASSERTED AGAINST BANK OR ANY OTHER INDEMNIFIED PERSON
BY ANY PERSON OR ENTITY UNDER ANY ENVIRONMENTAL LAWS OR SIMILAR LAWS BY REASON
OF THE BORROWER'S, GUARANTOR'S OR ANY OTHER PERSON'S OR ENTITY'S FAILURE TO
COMPLY WITH LAWS APPLICABLE TO SOLID OR HAZARDOUS WASTE MATERIALS OR OTHER TOXIC
SUBSTANCES. EACH INDEMNIFIED PERSON MAY SELECT ITS OWN COUNSEL WITH RESPECT TO
ANY LOSSES, IN ADDITION TO THE GUARANTOR'S COUNSEL, AND SHALL BE INDEMNIFIED
THEREFOR HEREUNDER. NOTWITHSTANDING ANY CONTRARY PROVISION OF THIS GUARANTY, THE
OBLIGATIONS OF THE GUARANTOR UNDER THIS SECTION 5.10 SHALL SURVIVE THE PAYMENT
IN FULL OF THE BORROWER'S OBLIGATIONS UNDER THE LOAN AGREEMENT AND THE
TERMINATION OF THE LOAN AGREEMENT AND THIS GUARANTY.

         Section 5.11. Replacement of Prior Guaranty. This Guaranty is given in
renewal, amendment, replacement, and restatement in its entirety (but not in
novation, extinguishment or satisfaction) of that certain Unconditional Guaranty
Agreement dated June 12, 1997, executed by Guarantor, formerly known as American
Medical Technologies, Inc. d/b/a AMT Industries, Inc., for the benefit of Bank,
successor-in-interest to Texas Commerce Bank National Association (the "Prior
Guaranty"). To the extent of any conflict between the terms of this Guaranty and
the terms of the Prior Guaranty, the terms of this Guaranty shall control.

         SECTION 5.12. NOTICE OF FINAL AGREEMENT. THIS GUARANTY CONSTITUTES A
WRITTEN AGREEMENT WHICH REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES. SUCH
WRITTEN AGREEMENT MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS,
OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL
AGREEMENTS BETWEEN THE PARTIES RELATING TO THIS GUARANTY.

                        UNCONDITIONAL GUARANTY AGREEMENT


         THIS UNCONDITIONAL GUARANTY AGREEMENT (this "Guaranty") is executed as
of April 1, 1999, by TIDEL SERVICES, INC., a Delaware corporation,
("Guarantor"), for the benefit of CHASE BANK OF TEXAS, N.A. ("Bank").


                                    RECITALS

         1. Pursuant to that certain Credit Agreement (as the same may be
amended, modified, increased, supplemented and/or restated from time to time,
the "Loan Agreement"), dated as of the date hereof and executed by and among
Tidel Engineering, L.P. ("Borrower"), Bank and Tidel Technologies, Inc., the
Bank has agreed to make certain loans to Borrower in the principal amount set
forth therein;

         2. The Bank is willing to make certain loans under the Loan Agreement
but only on the condition, among others, that Guarantor shall have executed and
delivered to Bank, for its benefit, this Guaranty; and

         3. Guarantor will derive substantial direct and indirect benefit from
the making of the loans under the Loan Agreement.

         NOW, THEREFORE, as an inducement to Bank to make certain loans to
Borrower, and to extend such additional credit as Bank may from time to time
agree to extend, and for other good and valuable consideration, the receipt and
legal sufficiency of which are hereby acknowledged, Guarantor, jointly and
severally, hereby agrees as follows:


                                   AGREEMENTS

                                    ARTICLE I

                          NATURE AND SCOPE OF GUARANTY

         Section 1.01. Guaranty of Obligations. Guarantor hereby irrevocably and
unconditionally guarantees to Bank and its successors and assigns the due and
punctual payment of the Obligations (hereinafter defined). Guarantor hereby
irrevocably and unconditionally covenants and agrees that it is liable for the
Obligations as primary obligor.

         Section 1.02. Definition of Obligations. As used herein, the term
"Obligations" means:

                  (a) All indebtedness, liabilities, obligations and duties
evidenced by the Notes (as such term is defined in the Loan Agreement), whether
or not Borrower has any recourse liability therefor to Bank and whether or not
the Notes are enforceable against Borrower or any other party liable thereon;

UNCONDITIONAL GUARANTY AGREEMENT - Page 1
(TIDEL SERVICES, INC.)

<PAGE>   2


                  (b) Any and all other indebtedness, liabilities, obligations
and duties of every kind and character of Borrower to Bank arising pursuant to
or related to the Loan Agreement, the Notes, or any loan agreement, security
agreement, collateral document or other document, instrument or contract
executed in connection with the Loan Agreement whether now or hereafter existing
or arising, regardless of whether such present or future indebtedness,
liabilities, obligations or duties be direct or indirect, primary or secondary,
joint, several, or joint and several, fixed or contingent, and regardless of
whether such present or future indebtedness, liabilities, obligations or duties
may, prior to their acquisition by Bank, be or have been payable to, or be or
have been in favor of, some other person or have been acquired by Bank in any
transaction with one other than Borrower including further, without limitation,
the "Obligations" as defined in the Loan Agreement;

                  (c) Any and all renewals, extensions, modifications and
increases of such indebtedness, liabilities, obligations and duties, or any part
thereof, described in items (a) and (b) of this SECTION 1.02; and

                  (d) All costs, expenses and fees, including but not limited to
court costs and attorneys' fees, arising in connection with the collection of
any or all amounts, indebtedness, obligations and liabilities of Borrower to
Bank described in items (a) through (c) of this SECTION 1.02 including costs,
expenses and fees arising in connection with the enforcement of this Guaranty.

         Section 1.03. Obligations Not Reduced by Offset. The Obligations, and
the liabilities and obligations of Guarantor to Bank hereunder, shall not be
reduced, discharged or released because or by reason of any existing or future
offset, claim or defense of Borrower, or any other party, against Bank or
against payment of the Obligations, whether such offset, claim or defense arises
in connection with the Obligations (or the transactions creating the
Obligations) or otherwise. Without limiting the foregoing or the Guarantor's
liability hereunder, to the extent that Bank advances funds or extends credit to
Borrower, and does not receive payments or benefits thereon in the amounts and
at the times required or provided by applicable agreements or laws, Guarantor is
absolutely liable to make such payments to (and confer such benefits on) Bank,
on a timely basis.

         Section 1.04. "Borrower" to Include Successors. The term "Borrower" as
used herein shall include any new or successor entity formed as a result of any
merger or reorganization of Borrower, and all other successors and assigns of
Borrower.

         Section 1.05. Payment by Guarantor. The Guarantor shall have the same
rights as Borrower under the Loan Agreement to cure any Event of Default (as
defined in the Loan Agreement) within the time periods, and otherwise in
accordance with the terms, provided in the Loan Agreement. If all or any part of
the Obligations shall not be punctually paid when due, whether at maturity or
earlier by acceleration or otherwise, Guarantor shall, immediately upon demand
by Bank, and without presentment, protest, notice of protest, notice of
non-payment, notice of intention to accelerate or acceleration or any other
notice whatsoever, pay in lawful money of the United States of America, the
amount due on the Obligations to Bank at Bank's

principal office in Dallas, Texas. Such demand(s) may be made at any time
coincident with or after the time for payment of all or part of the Obligations,
and may be made from time to time with respect to the same or different items of
Obligations. Such demand shall be deemed made, given and received in accordance
with SECTION 5.02 hereof.

         Section 1.06. No Duty to Pursue Others. It shall not be necessary for
Bank (and Guarantor hereby waives any rights which Guarantor may have to require
Bank), in order to enforce such payment by Guarantor, first to (a) institute
suit or exhaust its remedies against Borrower or others liable on the
Obligations or any other person, (b) enforce Bank's rights against any security
which shall ever have been given to secure the Obligations, (c) enforce Bank's
rights against any other guarantors of the Obligations, (d) join Borrower or any
others liable on the Obligations in any action seeking to enforce this Guaranty,
(e) exhaust any remedies available to Bank against any security which shall ever
have been given to secure the Obligations, or (f) resort to any other means of
obtaining payment of the Obligations. Guarantor hereby waives any other rights
of Guarantor provided by Tex. Bus. Comm. Code Ann. Art. 34. Bank shall not be
required to mitigate damages or take any other action to reduce, collect or
enforce the Obligations.

         Section 1.07. Waiver of Notices, etc. Guarantor hereby waives notice of
(a) any loans or advances made by Bank to Borrower, (b) acceptance of this
Guaranty, (c) any amendment or extension of the Loan Agreement, the Notes or of
any other instrument or document pertaining to all or any part of the
Obligations, (d) the execution and delivery by Borrower and Bank of the Loan
Agreement or of Borrower's execution and delivery of any promissory notes or
other documents in connection therewith, (e) Bank's transfer or disposition of
the Obligations, or any part thereof, (f) protest, proof of non-payment or
default by Borrower, or (g) any other action at any time taken or omitted by
Bank, and, generally, all demands and notices of every kind in connection with
this Guaranty, or any documents or agreements evidencing, securing or relating
to any of the Obligations, except as otherwise specifically provided herein.

         Section 1.08. Nature of Guaranty. This Guaranty is an irrevocable,
absolute, continuing guaranty of payment and performance and not a guaranty of
collection. This Guaranty shall continue to be effective with respect to any
Obligations existing or which arise out of commitments made by Bank prior to any
attempted revocation by Guarantor, and as to all renewals and extensions
thereof, in whole or in part, whenever made. The fact that at any time or from
time to time the Obligations may be increased or reduced shall not release,
discharge or reduce the obligation of Guarantor with respect to indebtedness or
obligations of Borrower to Bank thereafter incurred (or other Obligations
thereafter arising). This Guaranty may be enforced by Bank and any subsequent
holder of the Obligations and shall not be discharged by the assignment or
negotiation of all or part of the Obligations.

         Section 1.09. Payment of Expenses. In the event that Guarantor should
breach or fail to timely perform any provisions of this Guaranty, Guarantor
shall, immediately upon demand by Bank, pay Bank all costs and expenses
(including court costs and reasonable attorneys' fees) incurred by Bank in the
enforcement hereof or the preservation of Bank's rights hereunder. The covenant
contained in this SECTION 1.09 shall survive the payment of the Obligations.

         Section 1.10. Effect of Bankruptcy. In the event that, pursuant to any
insolvency, bankruptcy, reorganization, receivership or other debtor relief law,
or any judgment, order or decision thereunder, Bank must rescind or restore any
payment, or any part thereof, received by Bank in satisfaction of the
Obligations, any prior release or discharge from the terms of this Guaranty
given to Guarantor by Bank shall be without effect, and this Guaranty shall
remain in full force and effect. It is the intention of Guarantor that
Guarantor's obligations hereunder shall not be discharged except by Guarantor's
performance of such obligations and then only to the extent of such performance.


                                   ARTICLE II

              EVENTS AND CIRCUMSTANCES NOT REDUCING OR DISCHARGING

shareholders of Borrower; or any reorganization of Borrower;

         Section 2.04. Invalidity of Obligations. The invalidity, illegality or
unenforceability of all or any part of the Obligations, the Notes or any
document or agreement executed in connection with the Obligations, for any
reason whatsoever, including without limitation the fact that (a) the
Obligations, or any part thereof, exceeds the amount permitted by law, (b) the
act of creating the Obligations or any part thereof is ultra vires, (c) the
officers or representatives executing the documents creating the Obligations
acted in excess of their authority, (d) the Obligations violate applicable usury
laws, (e) Borrower has valid defenses, claims or offsets (whether at law, in
equity or by agreement) which render the Obligations wholly or partially

arises in connection with the Obligations (or the transactions creating the
Obligations) or otherwise;

         To induce Bank to extend credit to Borrower, Guarantor represents and

of Borrower and the terms of the Notes, Loan Agreement and other Loan Documents
(as defined in the Loan Agreement);

party has made any representation, warranty or statement to Guarantor in order
to induce Guarantor to execute this Guaranty;

         Section 3.03. Guarantor's Financial Condition. As of the date hereof,
and after giving effect to this Guaranty and the contingent obligation evidenced
hereby, Guarantor is, and will be, solvent, and has and will have assets which,
fairly valued, exceed its obligations, liabilities and debts, and has property
and assets sufficient to satisfy and repay its obligations and liabilities as
they mature;

         Section 3.06. Legality. The execution, delivery and performance by
Guarantor of this Guaranty and the consummation of the transactions contemplated
hereunder (a) have been duly authorized by all necessary corporate and
stockholder action of Guarantor, and (b) do not, and will not, contravene or
conflict with any law, statute or regulation whatsoever to which Guarantor is
subject or constitute a default (or an event which with notice or lapse of time
or both would constitute a default) under, or result in the breach of, any
indenture, mortgage, deed of trust, charge, lien, or any contract, agreement or
other instrument to which Guarantor is a party or which may be applicable to
Guarantor or any of its assets, or violate any provisions of its Articles (or
Certificate) of Incorporation, Bylaws or any other organizational document of

bankruptcy, insolvency or other laws of general application relating to the
enforcement of creditors' rights;

         Section 3.07. Organization and Good Standing. Guarantor (a) is, and

                                   ARTICLE IV

                     SUBORDINATION OF CERTAIN INDEBTEDNESS;
                              WAIVER OF SUBROGATION

         Section 4.01. Subordination of All Guarantor Claims. As used herein,
the term "Guarantor Claims" shall mean all debts and liabilities of Borrower to
Guarantor, whether such debts and liabilities now exist or are hereafter
incurred or arise, or whether the obligations of Borrower thereon be direct,
contingent, primary, secondary, several, joint and several, or otherwise, and
irrespective of whether such debts or liabilities be evidenced by note,
contract, open account, or otherwise, and irrespective of the person or persons
in whose favor such debts or liabilities may, at their inception, have been, or
may hereafter be created, or the manner in which they have been or may hereafter
be acquired by Guarantor. Except as otherwise allowed under the Loan Agreement,
until the Obligations shall be paid and satisfied in full, and in cash as to
monetary Obligations, and Guarantor shall have performed all of its obligations
hereunder, Guarantor shall not receive or collect, directly or indirectly, from
Borrower or any other party any amount upon the Guarantor Claims.

         Section 4.02. Waiver of Subrogation. Unless and until the Obligations
have been paid in full and subject to SECTION 4.07, Guarantor hereby waives and
releases, to the fullest extent permitted by law:


UNCONDITIONAL GUARANTY AGREEMENT - Page 7
(TIDEL SERVICES, INC.)

<PAGE>   8


                  (a) Any and all rights that would result in Guarantor being
         deemed a "creditor", under the United States Bankruptcy Code, of
         Borrower or any other person, on account of payments made or
         obligations performed by Guarantor relating to this Guaranty; and

                  (b) Any claim, right or remedy which Guarantor may now have or
         hereafter acquire against Borrower that arises hereunder and/or from
         the performance by any Guarantor hereunder including, without
         limitation, any claim, remedy or right of subrogation, reimbursement,
         exoneration, contribution, indemnification, or participation in any
         claim, right or remedy of Bank against Borrower or any security which
         now has or hereafter acquires, whether or not such claim, right or
         remedy arises in equity under contract, by statute, under common law or
         otherwise.

         Section 4.03. Claims in Bankruptcy. In the event of receivership,
bankruptcy, reorganization, arrangement, debtor's relief, or other insolvency
proceedings involving Borrower as debtor, Bank shall have the right to prove
their claims in any such proceeding so as to establish their rights hereunder
and receive directly from the receiver, trustee or other court custodian
dividends and payments which would otherwise be payable upon Guarantor Claims.
Guarantor hereby assigns such dividends and payments to Bank.

         Section 4.04. Payments Held in Trust. In the event that,
notwithstanding SECTIONS 4.01, 4.02 and 4.03 above, Guarantor should receive any
funds, payment, claim or distribution which is prohibited by such Sections,
Guarantor agrees to hold in trust for Bank an amount equal to the amount of all
funds, payments, claims or distributions so received, and agrees that it shall
have absolutely no dominion over the amount of such funds, payments, claims or
distributions, except to pay them promptly to Bank, and Guarantor covenants
promptly to pay the same to Bank.

         Section 4.05. Liens Subordinate. Guarantor agrees that any liens,
security interests, judgment liens, charges or other encumbrances upon
Borrower's assets securing payment of the Guarantor Claims shall be and remain
inferior and subordinate to any liens, security interests, judgment liens,
charges or other encumbrances upon Borrower's assets securing payment of the
Obligations, regardless of whether such encumbrances in favor of Guarantor or
Bank presently exist or are hereafter created or attached. Without the prior
written consent of Bank, Guarantor shall not (a) exercise or enforce any
creditor's right it may have against Borrower, or (b) foreclose, repossess,
sequester or otherwise take steps or institute any action or proceedings
(judicial or otherwise, including without limitation the commencement of, or
joinder in, any liquidation, bankruptcy, rearrangement, debtor's relief or
insolvency proceeding) to enforce any liens, mortgages, deeds of trust, security
interest, collateral rights, judgments or other encumbrances on assets of
Borrower held by Guarantor.

         Section 4.06. Notation of Records. All promissory notes, accounts
receivable ledgers or other evidences of the Guarantor Claims accepted by or
held by Guarantor shall contain a specific written notice thereon that the
indebtedness evidenced thereby is subordinated under the terms of this Guaranty.

         Section 4.07. Disgorged Payments. If after receipt of any payment of
all or any part of the Obligations, Bank is for any reason compelled to
surrender such payment to any person or


UNCONDITIONAL GUARANTY AGREEMENT - Page 8
(TIDEL SERVICES, INC.)

<PAGE>   9


entity because such payment is determined to be void or voidable as a
preference, impermissible setoff, or a diversion of trust funds, or for any
reason, this Guaranty shall continue in full force notwithstanding any contrary
action which may have been taken by Bank in reliance upon such payment, and any
such contrary action so taken shall be without prejudice to Bank's rights under
this Guaranty and shall be deemed to have been conditioned upon such payment
having become final and irrevocable.


                                    ARTICLE V

                                  MISCELLANEOUS

         Section 5.01. Waiver. No failure to exercise, and no delay in
exercising, on the part of Bank, any right hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise thereof preclude any other or
further exercise thereof or the exercise of any other right. The rights of Bank
hereunder shall be in addition to all other rights provided by law. No
modification or waiver of any provision of this Guaranty, nor consent to
departure therefrom, shall be effective unless in writing and signed by Bank and
no such consent or waiver shall extend beyond the particular case and purpose
involved. No notice or demand given in any case shall constitute a waiver of the
right to take other action in the same, similar or other instances without such
notice or demand.

         Section 5.02. Notices. Any notices or other communications required or
permitted to be given by this Guaranty must be given in writing and in the
manner set forth in the Loan Agreement. Any such notices or other communications
must be given to the Bank at the address set forth in the Loan Agreement and to
the Guarantor at the address set forth on the signature page hereto, or at such
other address as Guarantor or the Bank shall so designate in writing.

         Section 5.03. Usury Compliance. It is the intention of Borrower,
Guarantor and Bank to conform strictly to applicable usury laws. Accordingly, no
agreements, conditions, provisions or stipulations contained in this Guaranty or
any other instrument, document or agreement between Guarantor or Borrower and
Bank or default of Guarantor or Borrower, or the exercise by Bank of the right
to accelerate the payment of the maturity of principal and interest, or to
exercise any option whatsoever contained in this Guaranty or any other agreement
between Guarantor or Borrower and Bank, or the arising of any contingency
whatsoever, shall entitle Bank to collect, in any event, interest exceeding the
maximum rate of interest permitted by applicable state or federal law in effect
from time to time hereafter (the "Maximum Legal Rate") and in no event shall
Guarantor be obligated to pay interest exceeding such Maximum Legal Rate and all
agreements, conditions or stipulations, if any, which may in any event or
contingency whatsoever operate to bind, obligate or compel Guarantor to pay a
rate of interest exceeding the Maximum Legal Rate, shall be without binding
force or effect, at law or in equity, to the extent only of the excess of
interest over such Maximum Legal Rate. In the event any interest is charged in
excess of the Maximum Legal Rate ("Excess"), Guarantor acknowledges and
stipulates that any such charge shall be the result of an accident and bona fide
error, and such Excess shall be, first, applied to reduce the principal then
unpaid hereunder; second, applied to reduce the Obligations; and third, returned
to Guarantor, it being the intention of the parties


UNCONDITIONAL GUARANTY AGREEMENT - Page 9
(TIDEL SERVICES, INC.)

<PAGE>   10


hereto not to enter at any time into a usurious or otherwise illegal
relationship. Guarantor recognizes that, with fluctuations in the applicable
rate on the Obligations and the Maximum Legal Rate, such an unintentional result
could inadvertently occur. By the execution of this Guaranty, Guarantor
covenants that the credit or return of any Excess shall constitute the
acceptance by Guarantor of such Excess.

         Section 5.04. Choice of Law; Forum Selection. This Agreement and the
other Loan Documents are being executed and delivered, and are intended to be
performed in the State of Texas. Except to the extent that the laws of the
United States may apply to the terms of this Agreement or any other Loan
Document, the substantive laws of the State of Texas shall govern the validity,
construction, enforcement and interpretation of this Guaranty. In the event of a
dispute involving this Guaranty, Guarantor irrevocably agrees that venue for
such dispute shall lie in any court of competent jurisdiction in Dallas County,
Texas.

         Section 5.05. Invalid Provisions. In the case any one or more of the
provisions contained in this Guaranty should be invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained therein shall not in any way be affected thereby,
unless such continued effectiveness of this Guaranty, as modified, would be
contrary to the basic understandings and intentions of the parties as expressed
herein.

         Section 5.06. Parties Bound. This Guaranty shall be binding upon and
inure to the benefit of the parties hereto and their respective successors,
assigns and legal representatives; provided, however, that Guarantor may not,
without the prior written consent of Bank, assign any of its rights, powers,
duties or obligations hereunder.

         Section 5.07. Headings. Section headings are for convenience of
reference only and shall in no way affect the interpretation of this Guaranty.

         Section 5.08. Multiple Counterparts. This Guaranty may be executed in
multiple counterparts, all of which taken together shall constitute one and the
same agreement, and any of the parties hereto may execute this Guaranty by
signing any counterpart.

         Section 5.09. Rights and Remedies. If Guarantor becomes liable for any
indebtedness owing by Borrower to Bank, by endorsement or otherwise, other than
under this Guaranty, such liability shall not be in any manner impaired or
affected hereby and the rights of Bank hereunder shall be cumulative of any and
all other rights that Bank may ever have against Guarantor. The exercise by Bank
of any right or remedy hereunder or under any other instrument, or at law or in
equity, shall not preclude the concurrent or subsequent exercise of any other
right or remedy.

         SECTION 5.10. INDEMNITY. GUARANTOR HEREBY AGREES TO INDEMNIFY, HOLD
HARMLESS, AND DEFEND BANK AND ITS DIRECTORS, OFFICERS, AGENTS, COUNSEL AND
EMPLOYEES ("INDEMNIFIED PERSONS") FROM AND AGAINST ANY AND ALL LOSSES,
LIABILITIES, DAMAGES, COSTS, EXPENSES, SUITS, ACTIONS AND PROCEEDINGS ("LOSSES")
EVER SUFFERED OR INCURRED BY ANY INDEMNIFIED PERSON ARISING OUT OF OR RELATING
TO THIS GUARANTY, ANY OTHER LOAN DOCUMENT OR ANY OTHER

TRANSACTION CONTEMPLATED HEREBY AND THEREBY, INCLUDING, WITHOUT LIMITATION, ANY
LOSSES CAUSED BY THE NEGLIGENCE OF SUCH INDEMNIFIED PERSON, BUT NOT INCLUDING
ANY LOSSES CAUSED BY THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH
INDEMNIFIED PERSON OR THE DEFAULT BY SUCH INDEMNIFIED PERSON OF SUCH INDEMNIFIED
PERSON'S OBLIGATIONS UNDER ANY LOAN DOCUMENT, AND GUARANTOR SHALL REIMBURSE BANK
AND EACH OTHER INDEMNIFIED PERSON FOR ANY EXPENSES (INCLUDING IN CONNECTION WITH
THE INVESTIGATION OF, PREPARATION FOR OR DEFENSE OF ANY ACTUAL OR THREATENED
CLAIM, ACTION OR PROCEEDING ARISING HEREFROM AND THEREFROM, INCLUDING ANY SUCH
COSTS OF RESPONDING TO DISCOVERY REQUESTS OR SUBPOENAS, REGARDLESS OF WHETHER
BANK OR SUCH OTHER INDEMNIFIED PERSON IS A PARTY THERETO). WITHOUT LIMITING THE
GENERALITY OF THE FOREGOING, THIS INDEMNITY SHALL EXTEND TO ANY CLAIMS ASSERTED
AGAINST BANK OR ANY OTHER INDEMNIFIED PERSON BY ANY PERSON OR ENTITY UNDER ANY
ENVIRONMENTAL LAWS OR SIMILAR LAWS BY REASON OF THE BORROWER'S, GUARANTOR'S OR
ANY OTHER PERSON'S OR ENTITY'S FAILURE TO COMPLY WITH LAWS APPLICABLE TO SOLID
OR HAZARDOUS WASTE MATERIALS OR OTHER TOXIC SUBSTANCES. EACH INDEMNIFIED PERSON
MAY SELECT ITS OWN COUNSEL WITH RESPECT TO ANY LOSSES, IN ADDITION TO THE
GUARANTOR'S COUNSEL, AND SHALL BE INDEMNIFIED THEREFOR HEREUNDER.
NOTWITHSTANDING ANY CONTRARY PROVISION OF THIS GUARANTY, THE OBLIGATIONS OF THE
GUARANTOR UNDER THIS SECTION 5.10 SHALL SURVIVE THE PAYMENT IN FULL OF THE
BORROWER'S OBLIGATIONS UNDER THE LOAN AGREEMENT AND THE TERMINATION OF THE LOAN
AGREEMENT AND THIS GUARANTY.

         SECTION 5.11. NOTICE OF FINAL AGREEMENT. THIS GUARANTY CONSTITUTES A
WRITTEN AGREEMENT WHICH REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES. SUCH
WRITTEN AGREEMENT MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS,
OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL
AGREEMENTS BETWEEN THE PARTIES RELATING TO THIS GUARANTY.

         EXECUTED as of the day and year first above written.

                        UNCONDITIONAL GUARANTY AGREEMENT


         THIS UNCONDITIONAL GUARANTY AGREEMENT (this "Guaranty") is executed as
of April 1, 1999, by TIDEL CASH SYSTEMS, INC., a Delaware corporation,
("Guarantor"), for the benefit of CHASE BANK OF TEXAS, N.A. ("Bank").


                                    RECITALS

         1. Pursuant to that certain Credit Agreement (as the same may be
amended, modified, increased, supplemented and/or restated from time to time,
the "Loan Agreement"), dated as of the date hereof and executed by and among
Tidel Engineering, L.P. ("Borrower") Bank and Tidel Technologies, Inc., the Bank
has agreed to make certain loans to Borrower in the principal amount set forth
therein;

         2. The Bank is willing to make certain loans under the Loan Agreement
but only on the condition, among others, that Guarantor shall have executed and
delivered to Bank, for its benefit, this Guaranty; and

         3. Guarantor will derive substantial direct and indirect benefit from
the making of the loans under the Loan Agreement.

         NOW, THEREFORE, as an inducement to Bank to make certain loans to
Borrower, and to extend such additional credit as Bank may from time to time
agree to extend, and for other good and valuable consideration, the receipt and
legal sufficiency of which are hereby acknowledged, Guarantor, jointly and
severally, hereby agrees as follows:


                                   AGREEMENTS

                                    ARTICLE I

                          NATURE AND SCOPE OF GUARANTY

         Section 1.01. Guaranty of Obligations. Guarantor hereby irrevocably and
unconditionally guarantees to Bank and its successors and assigns the due and
punctual payment of the Obligations (hereinafter defined). Guarantor hereby
irrevocably and unconditionally covenants and agrees that it is liable for the
Obligations as primary obligor.

         Section 1.02. Definition of Obligations. As used herein, the term
"Obligations" means:

                  (a) All indebtedness, liabilities, obligations and duties
evidenced by the Notes (as such term is defined in the Loan Agreement), whether
or not Borrower has any recourse liability therefor to Bank and whether or not
the Notes are enforceable against Borrower or any other person liable thereon;


UNCONDITIONAL GUARANTY AGREEMENT - Page 1
(TIDEL CASH SYSTEMS, INC.)
<PAGE>   2

                  (b) Any and all other indebtedness, liabilities, obligations
and duties of every kind and character of Borrower to Bank arising pursuant to
or related to the Loan Agreement, the Notes, or any loan agreement, security
agreement, collateral document or other document, instrument or contract
executed in connection with the Loan Agreement whether now or hereafter existing
or arising, regardless of whether such present or future indebtedness,
liabilities, obligations or duties be direct or indirect, primary or secondary,
joint, several, or joint and several, fixed or contingent, and regardless of
whether such present or future indebtedness, liabilities, obligations or duties
may, prior to their acquisition by Bank, be or have been payable to, or be or
have been in favor of, some other person or have been acquired by Bank in any
transaction with one other than Borrower including further, without limitation,
the "Obligations" as defined in the Loan Agreement;

                  (c) Any and all renewals, extensions, modifications and
increases of such indebtedness, liabilities, obligations and duties, or any part
thereof, described in items (a) and (b) of this SECTION 1.02; and

                  (d) All costs, expenses and fees, including but not limited to
court costs and attorneys' fees, arising in connection with the collection of
any or all amounts, indebtedness, obligations and liabilities of Borrower to
Bank described in items (a) through (c) of this SECTION 1.02 including costs,
expenses and fees arising in connection with the enforcement of this Guaranty.

         Section 1.03. Obligations Not Reduced by Offset. The Obligations, and
the liabilities and obligations of Guarantor to Bank hereunder, shall not be
reduced, discharged or released because or by reason of any existing or future
offset, claim or defense of Borrower, or any other party, against Bank or
against payment of the Obligations, whether such offset, claim or defense arises
in connection with the Obligations (or the transactions creating the
Obligations) or otherwise. Without limiting the foregoing or the Guarantor's
liability hereunder, to the extent that Bank advances funds or extends credit to
Borrower, and does not receive payments or benefits thereon in the amounts and
at the times required or provided by applicable agreements or laws, Guarantor is
absolutely liable to make such payments to (and confer such benefits on) Bank,
on a timely basis.

         Section 1.04. "Borrower" to Include Successors. The term "Borrower" as
used herein shall include any new or successor entity formed as a result of any
merger or reorganization of Borrower, and all other successors and assigns of
Borrower.

         Section 1.05. Payment by Guarantor. The Guarantor shall have the same
rights as Borrower under the Loan Agreement to cure any Event of Default (as
defined in the Loan Agreement) within the time periods, and otherwise in
accordance with the terms, provided in the Loan Agreement. If all or any part of
the Obligations shall not be punctually paid when due, whether at maturity or
earlier by acceleration or otherwise, Guarantor shall, immediately upon demand
by Bank, and without presentment, protest, notice of protest, notice of
non-payment, notice of intention to accelerate or acceleration or any other
notice whatsoever, pay in lawful money of the United States of America, the
amount due on the Obligations to Bank at Bank's

principal office in Dallas, Texas. Such demand(s) may be made at any time
coincident with or after the time for payment of all or part of the Obligations,
and may be made from time to time with respect to the same or different items of
Obligations. Such demand shall be deemed made, given and received in accordance
with SECTION 5.02 hereof.

         Section 1.06. No Duty to Pursue Others. It shall not be necessary for
Bank (and Guarantor hereby waives any rights which Guarantor may have to require
Bank), in order to enforce such payment by Guarantor, first to (a) institute
suit or exhaust its remedies against Borrower or others liable on the
Obligations or any other person, (b) enforce Bank's rights against any security
which shall ever have been given to secure the Obligations, (c) enforce Bank's
rights against any other guarantors of the Obligations, (d) join Borrower or any
others liable on the Obligations in any action seeking to enforce this Guaranty,
(e) exhaust any remedies available to Bank against any security which shall ever
have been given to secure the Obligations, or (f) resort to any other means of
obtaining payment of the Obligations. Guarantor hereby waives any other rights
of Guarantor provided by Tex. Bus. Comm. Code Ann. Art. 34. Bank shall not be
required to mitigate damages or take any other action to reduce, collect or
enforce the Obligations.

         Section 1.07. Waiver of Notices, etc. Guarantor hereby waives notice of
(a) any loans or advances made by Bank to Borrower, (b) acceptance of this
Guaranty, (c) any amendment or extension of the Loan Agreement, the Notes or of
any other instrument or document pertaining to all or any part of the
Obligations, (d) the execution and delivery by Borrower and Bank of the Loan
Agreement or of Borrower's execution and delivery of any promissory notes or
other documents in connection therewith, (e) Bank's transfer or disposition of
the Obligations, or any part thereof, (f) protest, proof of non-payment or
default by Borrower, or (g) any other action at any time taken or omitted by
Bank, and, generally, all demands and notices of every kind in connection with
this Guaranty, or any documents or agreements evidencing, securing or relating
to any of the Obligations, except as otherwise specifically provided herein.

         Section 1.08. Nature of Guaranty. This Guaranty is an irrevocable,
absolute, continuing guaranty of payment and performance and not a guaranty of
collection. This Guaranty shall continue to be effective with respect to any
Obligations existing or which arise out of commitments made by Bank prior to any
attempted revocation by Guarantor, and as to all renewals and extensions
thereof, in whole or in part, whenever made. The fact that at any time or from
time to time the Obligations may be increased or reduced shall not release,
discharge or reduce the obligation of Guarantor with respect to indebtedness or
obligations of Borrower to Bank thereafter incurred (or other Obligations
thereafter arising). This Guaranty may be enforced by Bank and any subsequent
holder of the Obligations and shall not be discharged by the assignment or
negotiation of all or part of the Obligations.

         Section 1.09. Payment of Expenses. In the event that Guarantor should
breach or fail to timely perform any provisions of this Guaranty, Guarantor
shall, immediately upon demand by Bank, pay Bank all costs and expenses
(including court costs and reasonable attorneys' fees) incurred by Bank in the
enforcement hereof or the preservation of Bank's rights hereunder. The covenant
contained in this SECTION 1.09 shall survive the payment of the Obligations.

         Section 1.10. Effect of Bankruptcy. In the event that, pursuant to any
insolvency, bankruptcy, reorganization, receivership or other debtor relief law,
or any judgment, order or decision thereunder, Bank must rescind or restore any
payment, or any part thereof, received by Bank in satisfaction of the
Obligations, any prior release or discharge from the terms of this Guaranty
given to Guarantor by Bank shall be without effect, and this Guaranty shall
remain in full force and effect. It is the intention of Guarantor that
Guarantor's obligations hereunder shall not be discharged except by Guarantor's
performance of such obligations and then only to the extent of such performance.


                                   ARTICLE II

              EVENTS AND CIRCUMSTANCES NOT REDUCING OR DISCHARGING
                             GUARANTOR'S OBLIGATIONS

         Guarantor hereby consents and agrees to each of the following, and
agrees that Guarantor's obligations under this Guaranty shall not be released,
diminished, impaired, reduced or adversely affected by any of the following, and
waives any common law, equitable, statutory or other rights and defenses
(including without limitation rights to notice) which Guarantor might otherwise
have as a result of or in connection with any of the following:

         Section 2.01. Modifications, etc. Any renewal, extension, increase,
modification, alteration or rearrangement of all or any part of the Obligations,
or the Loan Agreement, the Notes or any loan agreement, security agreement,
collateral document or other document, instrument, contract or understanding
between Borrower and Bank, or any other parties, pertaining to the Obligations;

and after giving effect to this Guaranty and the contingent obligation evidenced

and assets sufficient to satisfy and repay its obligations and liabilities as

         Section 3.06. Legality. The execution, delivery and performance by
Guarantor of this Guaranty and the consummation of the transactions contemplated
hereunder (a) have been duly authorized by all necessary corporate and
stockholder action of Guarantor, and (b) do not, and will not, contravene or
conflict with any law, statute or regulation whatsoever to which Guarantor is
subject or constitute a default (or an event which with notice or lapse of time
or both would constitute a default) under, or result in the breach of, any
indenture, mortgage, deed of trust, charge, lien, or any contract, agreement or
other instrument to which Guarantor is a party or which may be applicable to
Guarantor or any of its assets, or violate any provisions of its Articles (or
Certificate) of Incorporation, Bylaws or any other organizational document of

enforcement of creditors' rights;

         Section 3.07. Organization and Good Standing. Guarantor (a) is, and
will continue to be, a corporation duly organized, validly existing, and in good

                              WAIVER OF SUBROGATION

         Section 4.01. Subordination of All Guarantor Claims. As used herein,
the term "Guarantor Claims" shall mean all debts and liabilities of Borrower to
Guarantor, whether such debts and liabilities now exist or are hereafter
incurred or arise, or whether the obligations of Borrower thereon be direct,
contingent, primary, secondary, several, joint and several, or otherwise, and
irrespective of whether such debts or liabilities be evidenced by note,
contract, open account, or otherwise, and irrespective of the person or persons
in whose favor such debts or liabilities may, at their inception, have been, or
may hereafter be created, or the manner in which they have been or may hereafter
be acquired by Guarantor. Except as otherwise allowed under the Loan Agreement,
until the Obligations shall be paid and satisfied in full, and in cash as to
monetary Obligations, and Guarantor shall have performed all of its obligations
hereunder, Guarantor shall not receive or collect, directly or indirectly, from
Borrower or any other party any amount upon the Guarantor Claims.

         Section 4.02. Waiver of Subrogation. Unless and until the Obligations

UNCONDITIONAL GUARANTY AGREEMENT - Page 7
(TIDEL CASH SYSTEMS, INC.)
<PAGE>   8

                  (a) Any and all rights that would result in Guarantor being
         deemed a "creditor", under the United States Bankruptcy Code, of
         Borrower or any other person, on account of payments made or
         obligations performed by Guarantor relating to this Guaranty; and

                  (b) Any claim, right or remedy which Guarantor may now have or
         hereafter acquire against Borrower that arises hereunder and/or from
         the performance by any Guarantor hereunder including, without
         limitation, any claim, remedy or right of subrogation, reimbursement,
         exoneration, contribution, indemnification, or participation in any
         claim, right or remedy of Bank against Borrower or any security which
         now has or hereafter acquires, whether or not such claim, right or
         remedy arises in equity under contract, by statute, under common law or
         otherwise.

         Section 4.03. Claims in Bankruptcy. In the event of receivership,
bankruptcy, reorganization, arrangement, debtor's relief, or other insolvency
proceedings involving Borrower as debtor, Bank shall have the right to prove
their claims in any such proceeding so as to establish their rights hereunder
and receive directly from the receiver, trustee or other court custodian
dividends and payments which would otherwise be payable upon Guarantor Claims.
Guarantor hereby assigns such dividends and payments to Bank.

         Section 4.04. Payments Held in Trust. In the event that,
notwithstanding SECTIONS 4.01, 4.02 and 4.03 above, Guarantor should receive any
funds, payment, claim or distribution which is prohibited by such Sections,
Guarantor agrees to hold in trust for Bank an amount equal to the amount of all
funds, payments, claims or distributions so received, and agrees that it shall
have absolutely no dominion over the amount of such funds, payments, claims or
distributions, except to pay them promptly to Bank, and Guarantor covenants
promptly to pay the same to Bank.

         Section 4.05. Liens Subordinate. Guarantor agrees that any liens,
security interests, judgment liens, charges or other encumbrances upon
Borrower's assets securing payment of the Guarantor Claims shall be and remain
inferior and subordinate to any liens, security interests, judgment liens,
charges or other encumbrances upon Borrower's assets securing payment of the
Obligations, regardless of whether such encumbrances in favor of Guarantor or
Bank presently exist or are hereafter created or attached. Without the prior
written consent of Bank, Guarantor shall not (a) exercise or enforce any
creditor's right it may have against Borrower, or (b) foreclose, repossess,
sequester or otherwise take steps or institute any action or proceedings
(judicial or otherwise, including without limitation the commencement of, or
joinder in, any liquidation, bankruptcy, rearrangement, debtor's relief or
insolvency proceeding) to enforce any liens, mortgages, deeds of trust, security
interest, collateral rights, judgments or other encumbrances on assets of
Borrower held by Guarantor.

         Section 4.06. Notation of Records. All promissory notes, accounts
receivable ledgers or other evidences of the Guarantor Claims accepted by or
held by Guarantor shall contain a specific written notice thereon that the
indebtedness evidenced thereby is subordinated under the terms of this Guaranty.

         Section 4.07. Disgorged Payments. If after receipt of any payment of
all or any part of the Obligations, Bank is for any reason compelled to
surrender such payment to any person or



UNCONDITIONAL GUARANTY AGREEMENT - Page 8
(TIDEL CASH SYSTEMS, INC.)
<PAGE>   9

entity because such payment is determined to be void or voidable as a
preference, impermissible setoff, or a diversion of trust funds, or for any
reason, this Guaranty shall continue in full force notwithstanding any contrary
action which may have been taken by Bank in reliance upon such payment, and any
such contrary action so taken shall be without prejudice to Bank's rights under
this Guaranty and shall be deemed to have been conditioned upon such payment
having become final and irrevocable.


                                    ARTICLE V

                                  MISCELLANEOUS

         Section 5.01. Waiver. No failure to exercise, and no delay in
exercising, on the part of Bank, any right hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise thereof preclude any other or
further exercise thereof or the exercise of any other right. The rights of Bank
hereunder shall be in addition to all other rights provided by law. No
modification or waiver of any provision of this Guaranty, nor consent to
departure therefrom, shall be effective unless in writing and signed by Bank and
no such consent or waiver shall extend beyond the particular case and purpose
involved. No notice or demand given in any case shall constitute a waiver of the
right to take other action in the same, similar or other instances without such
notice or demand.

         Section 5.02. Notices. Any notices or other communications required or
permitted to be given by this Guaranty must be given in writing and in the
manner set forth in the Loan Agreement. Any such notices or other communications
must be given to the Bank at the address set forth in the Loan Agreement and to
the Guarantor at the address set forth on the signature page hereto or at such
other address as Guarantor or the Bank shall so designate in writing.

         Section 5.03. Usury Compliance. It is the intention of Borrower,
Guarantor and Bank to conform strictly to applicable usury laws. Accordingly, no
agreements, conditions, provisions or stipulations contained in this Guaranty or
any other instrument, document or agreement between Guarantor or Borrower and
Bank or default of Guarantor or Borrower, or the exercise by Bank of the right
to accelerate the payment of the maturity of principal and interest, or to
exercise any option whatsoever contained in this Guaranty or any other agreement
between Guarantor or Borrower and Bank, or the arising of any contingency
whatsoever, shall entitle Bank to collect, in any event, interest exceeding the
maximum rate of interest permitted by applicable state or federal law in effect
from time to time hereafter (the "Maximum Legal Rate") and in no event shall
Guarantor be obligated to pay interest exceeding such Maximum Legal Rate and all
agreements, conditions or stipulations, if any, which may in any event or
contingency whatsoever operate to bind, obligate or compel Guarantor to pay a
rate of interest exceeding the Maximum Legal Rate, shall be without binding
force or effect, at law or in equity, to the extent only of the excess of
interest over such Maximum Legal Rate. In the event any interest is charged in
excess of the Maximum Legal Rate ("Excess"), Guarantor acknowledges and
stipulates that any such charge shall be the result of an accident and bona fide
error, and such Excess shall be, first, applied to reduce the principal then
unpaid hereunder; second, applied to reduce the Obligations; and third, returned
to Guarantor, it being the intention of the parties



UNCONDITIONAL GUARANTY AGREEMENT - Page 9
(TIDEL CASH SYSTEMS, INC.)
<PAGE>   10

hereto not to enter at any time into a usurious or otherwise illegal
relationship. Guarantor recognizes that, with fluctuations in the applicable
rate on the Obligations and the Maximum Legal Rate, such an unintentional result
could inadvertently occur. By the execution of this Guaranty, Guarantor
covenants that the credit or return of any Excess shall constitute the
acceptance by Guarantor of such Excess.

         Section 5.04. Choice of Law; Forum Selection. This Agreement and the
other Loan Documents are being executed and delivered, and are intended to be
performed in the State of Texas. Except to the extent that the laws of the
United States may apply to the terms of this Agreement or any other Loan
Document, the substantive laws of the State of Texas shall govern the validity,
construction, enforcement and interpretation of this Guaranty. In the event of a
dispute involving this Guaranty, Guarantor irrevocably agrees that venue for
such dispute shall lie in any court of competent jurisdiction in Dallas County,
Texas.

         Section 5.05. Invalid Provisions. In the case any one or more of the
provisions contained in this Guaranty should be invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained therein shall not in any way be affected thereby,
unless such continued effectiveness of this Guaranty, as modified, would be
contrary to the basic understandings and intentions of the parties as expressed
herein.

         Section 5.06. Parties Bound. This Guaranty shall be binding upon and
inure to the benefit of the parties hereto and their respective successors,
assigns and legal representatives; provided, however, that Guarantor may not,
without the prior written consent of Bank, assign any of its rights, powers,
duties or obligations hereunder.

         Section 5.07. Headings. Section headings are for convenience of
reference only and shall in no way affect the interpretation of this Guaranty.

         Section 5.08. Multiple Counterparts. This Guaranty may be executed in
multiple counterparts, all of which taken together shall constitute one and the
same agreement, and any of the parties hereto may execute this Guaranty by
signing any counterpart.

         Section 5.09. Rights and Remedies. If Guarantor becomes liable for any
indebtedness owing by Borrower to Bank, by endorsement or otherwise, other than
under this Guaranty, such liability shall not be in any manner impaired or
affected hereby and the rights of Bank hereunder shall be cumulative of any and
all other rights that Bank may ever have against Guarantor. The exercise by Bank
of any right or remedy hereunder or under any other instrument, or at law or in
equity, shall not preclude the concurrent or subsequent exercise of any other
right or remedy.

         SECTION 5.10. INDEMNITY. GUARANTOR HEREBY AGREES TO INDEMNIFY, HOLD
HARMLESS, AND DEFEND BANK AND ITS DIRECTORS, OFFICERS, AGENTS, COUNSEL AND
EMPLOYEES ("INDEMNIFIED PERSONS") FROM AND AGAINST ANY AND ALL LOSSES,
LIABILITIES, DAMAGES, COSTS, EXPENSES, SUITS, ACTIONS AND PROCEEDINGS ("LOSSES")
EVER SUFFERED OR INCURRED BY ANY INDEMNIFIED PERSON ARISING OUT OF OR RELATING

CLAIM, ACTION OR PROCEEDING ARISING HEREFROM AND THEREFROM, INCLUDING ANY SUCH
COSTS OF RESPONDING TO DISCOVERY REQUESTS OR SUBPOENAS, REGARDLESS OF WHETHER

GENERALITY OF THE FOREGOING, THIS INDEMNITY SHALL EXTEND TO ANY CLAIMS ASSERTED
AGAINST BANK OR ANY OTHER INDEMNIFIED PERSON BY ANY PERSON OR ENTITY UNDER ANY
ENVIRONMENTAL LAWS OR SIMILAR LAWS BY REASON OF THE BORROWER'S, GUARANTOR'S OR
ANY OTHER PERSON'S OR ENTITY'S FAILURE TO COMPLY WITH LAWS APPLICABLE TO SOLID

MAY SELECT ITS OWN COUNSEL WITH RESPECT TO ANY LOSSES, IN ADDITION TO THE
GUARANTOR'S COUNSEL, AND SHALL BE INDEMNIFIED THEREFOR HEREUNDER.
NOTWITHSTANDING ANY CONTRARY PROVISION OF THIS GUARANTY, THE OBLIGATIONS OF THE
GUARANTOR UNDER THIS SECTION 5.10 SHALL SURVIVE THE PAYMENT IN FULL OF THE
BORROWER'S OBLIGATIONS UNDER THE LOAN AGREEMENT AND THE TERMINATION OF THE LOAN
AGREEMENT AND THIS GUARANTY.

         SECTION 5.11. NOTICE OF FINAL AGREEMENT. THIS GUARANTY CONSTITUTES A
WRITTEN AGREEMENT WHICH REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES. SUCH
WRITTEN AGREEMENT MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS,
OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL
AGREEMENTS BETWEEN THE PARTIES RELATING TO THIS GUARANTY.

hereinafter incurred under, arising out of or in connection with this Agreement,
(ii) the prompt and complete payment when due (whether at the stated due date,
by acceleration or otherwise) of the unpaid principal of and interest on the
Notes issued to evidence the Loans made by Pledgee to Borrower pursuant to the
Loan Agreement as well as collection costs therefor, and (iii) the due and
punctual payment and performance by Borrower of all Obligations (as defined in
the Loan Agreement) to Pledgee, absolute or contingent, liquidated or
unliquidated, now existing or hereinafter incurred (all the foregoing being
hereinafter called the "Obligations").

         3. Stock Dividends, Distributions, etc. If, while this Agreement is in
effect, the Pledgor shall become entitled to receive or shall receive any Stock
certificate (including, without limitation, any certificate representing a Stock
dividend or a distribution in connection with any reclassification, increase or
reduction of capital, or issued in connection with any reorganization), option
or rights, whether as an addition to, in substitution of, or in exchange for any
shares of any Pledged Stock, or otherwise, the Pledgor agrees to accept the same
as Pledgee's agent and to hold the same in trust on behalf of and for the
benefit of the Pledgee segregated from the other assets of the Pledgor and to
deliver the same forthwith to the Pledgee, in the exact form received, with the
endorsement of the Pledgor, when necessary and/or appropriate, to undated stock
powers, duly executed in blank, to be held by the Pledgee, subject to the terms
hereof, as additional collateral security for the Obligations, and such other
documents as the Pledgee shall reasonably request in order to perfect the
Pledgee's security interest therein. Any sums paid upon or in respect of the
Pledged Stock upon the liquidation or dissolution of any Issuer shall be paid
over to the Pledgee, to be held by it in trust as additional collateral security
for the Obligations; and in case any distribution of capital shall be made on or
in respect of the Pledged Stock or any property shall be distributed upon or
with respect to the


PLEDGE AND SECURITY AGREEMENT (TIDEL TECHNOLOGIES, INC.) - Page 2


<PAGE>   3

Pledged Stock pursuant to the recapitalization or reclassification of the
capital of any Issuer or pursuant to the reorganization thereof, the property so
distributed shall be delivered to the Pledgee, to be held by it as additional
collateral security for the Obligations. All sums of money and property so paid
or distributed in respect of the Pledged Stock which are received by the Pledgor
shall, until paid or delivered to the Pledgee, be held by the Pledgor in trust,
segregated from the other assets of the Pledgor, as additional collateral
security for the Obligations.

         4. Collateral. The Pledged Stock and all other property at any time and
from time to time pledged to Pledgee hereunder (whether described in SCHEDULE l
hereof or not) and all income therefrom and proceeds thereof, are herein
collectively sometimes called the "Collateral".

         5. Record Ownership of Pledged Stock. Whether or not an Event of
Default has occurred and is continuing, Pledgee at any time may have the Pledged
Stock registered in its name, or in the name of its nominee or nominees, as
pledgee; and, as to any Pledged Stock so registered, Pledgee shall execute and
deliver (or cause to be executed and delivered) to Pledgor all such proxies,
powers of attorney, dividend coupons or orders, and other documents as Pledgor
may reasonably request for the purpose of enabling Pledgor to exercise the
voting rights and powers which it is entitled to exercise under this Agreement
and to receive the dividends and other payments in respect of the Pledged Stock
which it is authorized to receive and retain under this Agreement and the Loan
Agreement.

         6. Voting of Pledged Stock. As long as an Event of Default has not
occurred and is not continuing, Pledgor shall be entitled to exercise all voting
rights pertaining to the Pledged Stock; provided, however, that no vote shall be
cast or consent, waiver or ratification given or action taken which would impair
the Collateral or violate any provision of this Agreement, the Loan Agreement or
the Loan Documents. After the occurrence and during the continuance of an Event
of Default, the right to vote the Pledged Stock and all other corporate rights
pertaining to the Pledged Stock shall be vested exclusively in Pledgee,
including any and all rights of conversion, exchange, subscription or any other
rights, privileges or options pertaining to any shares of the Pledged Stock as
if Pledgee were the absolute owner thereof, including, without limitation, the
right to exchange at its discretion any and all of the Pledged Stock upon the
merger, consolidation, reorganization, recapitalization or other readjustment of
any Issuer or upon the exercise by such Issuer or the Pledgee of any right,
privilege or option pertaining to any shares of the Pledged Stock, and in
connection therewith, to deposit and deliver any and all of the Pledged Stock
with any committee, depositary, transfer agent, registrar or other designated
agency upon such terms and conditions as it may determine, all without liability
except to account for property actually received by it, but the Pledgee shall
have no duty to exercise any of the aforesaid rights, privileges or options or
be responsible for any failure to do so or delay in so doing. To this end,
Pledgor hereby irrevocably constitutes and appoints Pledgee the proxy and
attorney-in-fact of Pledgor, with full power of substitution, to vote, and to
act with respect to, the Pledged Stock standing in the name of Pledgor or with
respect to which Pledgor is entitled to vote and act, subject to the
understanding that such proxy may not be exercised unless an Event of Default
has occurred and is continuing. The proxy herein granted is coupled with an
interest, is irrevocable, and shall continue until the Obligations have been
paid and performed in full.


PLEDGE AND SECURITY AGREEMENT (TIDEL TECHNOLOGIES, INC.) - Page 3

         7. Limitations on Pledgee's Obligations. The Pledgee shall not be
liable for failure to collect or realize upon the Obligations or any collateral
security or guarantee therefor, or any part thereof, or for any delay in so
doing nor shall the Pledgee be under any obligation to take any action
whatsoever with regard thereto.

         8. The Pledgee's Appointment as Attorney-in-Fact. (a) In addition to,
and without limiting the scope of any other provision in this Agreement, the
Pledgor hereby irrevocably constitutes and appoints the Pledgee and any officer
or agent thereof, with full power of substitution, as its true and lawful
attorney-in-fact with full irrevocable power and authority in the place and
stead of the Pledgor and in the name of the Pledgor or in its own name, from
time to time in the Pledgee's discretion, for the purpose of carrying out the
actions and to execute any and all documents and instruments which may be
necessary or desirable to accomplish the purposes of this Agreement and, without
limiting the generality of the foregoing, hereby gives the Pledgee the power and
right, on behalf of the Pledgor, without notice to or assent by the Pledgor to
do the following upon the occurrence and during the continuance of an Event of
Default: (i) to ask, demand, collect, receive and give acquittances and receipts
for any and all monies due and to become due under the Collateral; (ii) in the
name of the Pledgor or its own name or otherwise, to take possession of and
endorse and collect any checks, drafts, notes, acceptances or other instruments
for the payment of moneys due under the Collateral; (iii) to file any claim or
to take any other action or proceeding in any court of law or equity or
otherwise deemed appropriate by the Pledgee for the purpose of collecting any
and all such moneys due under the Collateral whenever payable; (iv) to pay or
discharge taxes, liens, security interests or other encumbrances levied or
placed on or threatened against the Collateral; (v) to direct any party liable
for any payment under the Collateral to make payment of any and all moneys due
and to become due thereunder directly to the Pledgee or as the Pledgee shall
direct; (vi) to receive payment of and receipt for any and all moneys, claims
and other amounts due and to become due at any time in respect of or arising out
of any Collateral; (vii) to commence and prosecute any suits, actions or
proceedings at law or in equity in any court of competent jurisdiction to
collect the Collateral or any part thereof and to enforce any other right in
respect of the Collateral; (viii) to defend any suit, action or proceeding
brought against the Pledgor with respect to any Collateral; (ix) to settle,
compromise or adjust any suit, action or proceeding described above and, in
connection therewith, to give such discharges or releases as the Pledgee may
deem appropriate; (x) exercise voting rights attributable to the Pledged Stock
pursuant to SECTION 6; and (xi) generally to sell, transfer, pledge, make any
agreement with respect to or otherwise deal with any of the Collateral as fully
and completely as though the Pledgee were the absolute owner thereof for all
purposes, and to do, at the Pledgee's option and the Pledgor's expense, at any
time, or from time to time, all acts and things which the Pledgee deems
necessary to protect, preserve or realize upon the Collateral and the Pledgee's
security interest therein, in order to effect the intent of this Agreement, all
as fully and effectively as the Pledgor might do.

         The Pledgor hereby ratifies all that said attorneys shall lawfully do
or cause to be done by virtue hereof. This power of attorney is a power coupled
with an interest and shall be irrevocable.


PLEDGE AND SECURITY AGREEMENT (TIDEL TECHNOLOGIES, INC.) - Page 4


<PAGE>   5

         (b) The powers conferred on the Pledgee hereunder are solely to protect
its interests in the Collateral and shall not impose any duty upon it to
exercise any such powers. Pledgee shall be accountable only for amounts that it
actually receives as a result of the exercise of such powers and neither it nor
any of its officers, directors, employees or agents shall be responsible to the
Pledgor for any act or failure to act.

         (c) The Pledgor also authorizes the Pledgee, at any time and from time
to time, to execute, in connection with any sale of the Collateral, any
endorsements, assignments or other instruments of conveyance or transfer with
respect to the Collateral.

         9. Performance by the Pledgee of the Pledgor's Obligations. If the
Pledgor fails to perform or comply with any of its agreements contained herein
and the Pledgee, as provided for by the terms of this Agreement, shall itself
perform or comply, or otherwise cause performance or compliance, with such
agreement, then the expenses of the Pledgee incurred in connection with such
performance or compliance, together with interest thereon to accrue at a rate of
interest equal to the Highest Lawful Rate from the date such expenses are
incurred, shall be payable by the Pledgor to the Pledgee on demand and shall
constitute Obligations secured hereby.

         10. Events of Default. The occurrence of any of the following shall
constitute an "Event of Default" under this Agreement:

         (a) The Pledgor shall fail to pay its Obligations when due;

         (b) Any representation, warranty or statement made or deemed made by
the Pledgor herein or in connection herewith shall prove to have been incorrect
or untrue in any material respect on or as of the date made or deemed made;

         (c) The Pledgor shall default in the observance or performance of any
term, covenant, or agreement contained herein and Pledgor shall fail to cure
such default within fifteen (15) days after the occurrence of such default; or

         (d) An Event of Default (subject to any applicable cure period), as
such term is defined in the Loan Agreement, shall occur and be continuing.

         11. Remedies. (a) Upon the occurrence and during the continuance of any
Event of Default, and at any time thereafter, the Pledgee may declare all of the
Obligations or any part thereof immediately due and payable and, without demand
of performance or other demand, advertisement or notice of any kind (except the
notice specified below of time and place of public or private sale) to or upon
the Pledgor or any other person (all and each of which demands, advertisements
and/or notices are hereby expressly waived), may forthwith collect, receive,
appropriate and realize upon the Collateral, or any part thereof, and/or may
forthwith sell, assign, give option or options to purchase, contract to sell or
otherwise dispose of and deliver said Collateral, or any part thereof, in one or
more parcels at public or private sale or sales, at any exchange, broker's board
or at the Pledgee's offices or elsewhere upon such terms and conditions as it
may deem advisable and at such prices as it may deem best, for cash or on credit
or for future delivery without assumption of any credit risk, with the right to
the Pledgee


PLEDGE AND SECURITY AGREEMENT (TIDEL TECHNOLOGIES, INC.) - Page 5


<PAGE>   6

upon any such sale or sales, public or private, to purchase the whole or any
part of said Collateral so sold, free of any right or equity of redemption in
the Pledgor, which right or equity is hereby expressly waived or released. The
Pledgee shall apply the net proceeds of any such collection, recovery, receipt,
appropriation, realization or sale, after deducting all reasonable costs and
expenses of every kind incurred therein or incidental to the care, safekeeping
or otherwise of any and all of the Collateral or in any way relating to the
rights of the Pledgee hereunder, including reasonable attorneys' fees and legal
expenses, to the payment in whole or in part of the Obligations in such order as
the Pledgee may elect, the Pledgor remaining liable for any deficiency remaining
unpaid after such application, and only after so applying such net proceeds and
after the payment by the Pledgee of any amount required by any provision of law,
including, without limitation, Section 9-504 (a) (3) of the Uniform Commercial
Code of the State of Texas (the "Code"), need the Pledgee account for the
surplus, if any, to the Pledgor. The Pledgor agrees that, to the extent
permitted by law, the Pledgee need not give more than ten (10) days' notice of
the time and place of any public sale or of the time after which a private sale
or other intended disposition is to take place and that such notice is
reasonable notification of such matters. No notification need be given to the
Pledgor if it has signed after default a statement renouncing or modifying any
right to notification of sale or other intended disposition. IN ADDITION TO THE
RIGHTS AND REMEDIES GRANTED TO IT IN THIS AGREEMENT AND IN ANY OTHER INSTRUMENT
OR AGREEMENT SECURING, EVIDENCING OR RELATING TO ANY OF THE OBLIGATIONS, THE
PLEDGEE SHALL HAVE ALL THE RIGHTS AND REMEDIES OF A SECURED PARTY UNDER THE
CODE. All waivers by the Pledgor of rights (including rights to notice) and all
rights and remedies afforded the Pledgor herein, and all other provisions of
this Agreement, are expressly made subject to any applicable mandatory
provisions of law limiting, or imposing conditions (including conditions as to
reasonableness) upon such waivers of the effectiveness thereof or any such
rights and remedies. Any sale or other disposition of the Collateral shall be in
compliance with all provisions of law (including applicable securities laws, and
regulations and applicable provisions of the Code).

         (b) If Pledgee shall determine to exercise its right to sell any or all
of the Pledged Stock pursuant to this SECTION 11 hereof, and if in the opinion
of counsel for Pledgee it is advisable to have the Pledged Stock, or that
portion thereof to be sold, registered under the provisions of the Securities
Act of 1933, as amended (the "Securities Act"), the Pledgor will cause the
Issuer of such Pledged Stock to execute and deliver, and cause the directors and
officers thereof to execute and deliver, all at the Pledgor's expense, all such
instruments and documents, and to do or cause to be done all such other acts and
things as may be necessary to register the Pledged Stock, or that portion
thereof to be sold, under the provisions of the Securities Act and to cause the
registration statement relating thereto to become effective and to remain
effective for a period of 180 days from the date of the first public offering of
the Pledged Stock, or that portion thereof to be sold, and to make all
amendments thereto and/or to the related prospectus which are necessary, all in
conformity with the requirements of the Securities Act and the rules and
regulations of the Securities and Exchange Commission applicable thereto. The
Pledgor agrees to cause each Issuer to comply with the provisions of the
securities or "Blue Sky" laws of any jurisdiction which Pledgee shall designate
and to cause each Issuer to make available to its security holders, as soon as
practicable, an earnings statement which will satisfy the provisions of Section
11(a) of the Securities Act.


PLEDGE AND SECURITY AGREEMENT (TIDEL TECHNOLOGIES, INC.) - Page 6


<PAGE>   7

         (c) The Pledgor recognizes that the Pledgee may be unable to effect a
public sale of any or all the Pledged Stock by reason of certain prohibitions
contained in the Securities Act and applicable state securities laws, but may be
compelled to resort to one or more private sales thereof to a restricted group
of purchasers who will be obliged to agree, among other things, to acquire such
securities for their own account for investment and not with a view to the
distribution or resale thereof. The Pledgor acknowledges and agrees that any
such private sale may result in prices and other terms less favorable to the
seller than if such sale were a public sale and, notwithstanding such
circumstances, agrees that any such private sale shall be deemed to have been
made in a commercially reasonable manner. Pledgee shall be under no obligation
to delay a sale of any of the Pledged Stock for the period of time necessary to
permit the Issuer of such securities to register such securities for public sale
under the Securities Act, or under applicable state securities laws, even if
such Issuer would agree to do so.

         (d) The Pledgor further agrees to do or cause to be done all such other
acts and things as may be necessary to make such sale or sales of any portion of
all of the Pledged Stock valid and binding and in compliance with any and all
applicable laws, regulations, orders, writs, injunctions, decrees or awards of
any and all courts, arbitrators or governmental instrumentalities, domestic or
foreign, having jurisdiction over any such sale or sales, all at the Pledgor's
expense. The Pledgor further agrees that a breach of any of the covenants
contained in this SECTION 11 will cause irreparable injury to Pledgee, that
Pledgee has no adequate remedy at law in respect of such breach and, as a
consequence, agrees that each and every covenant contained in this paragraph
shall be specifically enforceable against the Pledgor and the Pledgor hereby
waives and agrees not to assert any defenses against an action for specific
performance of such covenants except for a defense that no default of the
covenants, terms or conditions of the Loan Agreement has occurred. The Pledgor
further acknowledges the impossibility of ascertaining the amount of damages
which would be suffered by Pledgee by reason of a breach of any such covenants
and, consequently, agrees that, if Pledgee shall sue for damages for breach,
Pledgor shall pay, as liquidated damages and not as a penalty, an amount equal
to the value of the Pledged Stock on the date Pledgee shall demand compliance
with this paragraph, but in no event to exceed the amount of the Obligations.

         12. Waiver of Subrogation. Notwithstanding anything to the contrary in
this Agreement, unless and until the Obligations have been indefeasibly paid and
performed in full, the Pledgor hereby irrevocably waives all rights Pledgor may
have at law or in equity (including, without limitation, any law subrogating the
Pledgor to the rights of the Pledgee) to seek contribution, indemnification, or
any other form of reimbursement from the Issuer, any other guarantor or pledgor,
or any other person now or hereafter primarily or secondarily liable for any
obligations of the Borrower to the Pledgee, for any disbursement made by the
Pledgor under or in connection with this Agreement or otherwise. The Pledgor
further agrees that, to the extent that the waiver of any such subrogation,
contribution, reimbursement, indemnity or otherwise is found to be void or
voidable for any reason, any such rights which the Pledgor may have shall be
junior and subordinate in all respects to the rights of the Pledgee against the
Borrower.

         13. Actions by Pledgee. No action that the Pledgee may take or omit to
take in connection with the Loan Agreement or any of the Loan Documents, any
indebtedness owing by


PLEDGE AND SECURITY AGREEMENT (TIDEL TECHNOLOGIES, INC.) - Page 7


<PAGE>   8

Borrower to the Pledgee (including, without limitation, renewals, extensions,
modifications and increases thereof), or any security for the payment of any
indebtedness of Borrower to the Pledgee, or for the performance of any
obligation or undertaking of Borrower, nor any course of dealing with Borrower
or any other Person, shall release the Pledgor from its obligations hereunder,
affect this Agreement in any way, or afford the Pledgor any recourse against the
Pledgee. By way of example, but not in limitation of the foregoing, the Pledgor
hereby expressly agrees that the Pledgee may, from time to time, without notice
to the Pledgor:

                  (a) sell, assign, transfer or grant participations in the
Loans and/or any right held by the Pledgee pursuant to or in connection with the
Loan Agreement and the Loan Documents;

                  (b) amend, change, or modify, in whole or in part, any
documents or instruments evidencing, securing or relating to any indebtedness or
undertaking of Borrower to the Pledgee;

                  (c) accelerate, change, extend, or renew the time for payment
of the Notes or any other indebtedness arising under any documents or
instruments evidencing, securing or relating to any indebtedness or undertaking
of Borrower to the Pledgee;

                  (d) compromise or settle any amount due or owing, or claimed
to be due or owing, under the Notes or under any documents or instruments
evidencing, securing or relating to any indebtedness or undertaking of Borrower
to the Pledgee;

                  (e) surrender, release, or subordinate any or all security for
any indebtedness or undertaking of Borrower to the Pledgee or accept additional
or substituted security therefor;

                  (f) release any guarantor or pledgor of any indebtedness or
undertaking of the Borrower to the Pledgee, or substitute or add additional
guarantors or pledgors; and

                  (g) apply collateral securing the Notes to other indebtedness
also secured by such collateral.

The provisions of this Agreement shall extend and be applicable to all renewals,
increases, amendments, extensions, modifications of and substitutions for the
Loan Agreement and the Loan Documents, and all references herein to the Loan
Agreement and the Loan Documents shall be deemed to include any renewal,
increase, extension, amendment or modification thereof or substitution therefor.

         14. No Impairment. The obligations, guaranties, undertakings,
covenants, agreements and duties of the Pledgor under this Agreement shall not
be affected or impaired by any of the following, although without notice to or
consent of the Pledgor:

         (a) any failure, omission or delay on the part of the Pledgee (i) to
enforce, assert or exercise any right, power or remedy conferred on the Pledgee
by the provisions of the Loan Agreement and the Loan Documents or otherwise
inuring to the holders of the rights of the Pledgee under the Loan Agreement and
the Loan Documents, or (ii) to make demand first upon Borrower or to proceed
against Borrower;


PLEDGE AND SECURITY AGREEMENT (TIDEL TECHNOLOGIES, INC.) - Page 8


<PAGE>   9

         (b) the voluntary or involuntary liquidation, dissolution, sale of all
or substantially all assets, marshalling of assets or liabilities, receivership,
conservatorship, assignment for the benefit of creditors, insolvency,
bankruptcy, reorganization, arrangement, composition or other proceedings under
laws for the protection of debtors affecting Borrower or any of the assets of
Borrower, or any discharge from liability or rejection of burdensome contracts
or obligations in the course of or resulting from any such proceedings;

         (c) the release, by operation of law or otherwise, of Borrower or any
guarantor from any obligation under the Loan Agreement or any of the Loan
Documents;

         (d) the invalidity, deficiency, illegality or unenforceability of the
Loan Agreement and the Loan Documents, in whole or in part, or of any of the
provisions thereof, or failure to perfect or maintain perfection of any
security, or any defense or excuse for failure to perform on account of force
majeure, act of God, casualty, impossibility, impracticability, or other defense
or excuse whatsoever; or

         (e) without limiting the foregoing, any fact or event (whether or not
similar to any of the foregoing) which in the absence of this provision would or
might constitute or afford a legal or equitable discharge or release of or
defense to a guarantor or surety.

None of the foregoing shall be a defense to this Agreement, and this Agreement
is a primary obligation of the Pledgor.

         15. Other Pledgors or Guarantors. The liabilities and obligations of
the Pledgor hereunder shall not be reduced or limited by reason of any guaranty
or pledge executed in favor of the Pledgee by any other Person, and this
Agreement shall be enforceable against the Pledgor without regard to any such
guaranty or pledge.

         16. Representations, Warranties and Covenants of the Pledgor. The
Pledgor represents and warrants that (a) it is the legal, record and beneficial
owner of, and has good and, subject to applicable securities laws described in
SECTION 11 hereof, marketable title to, the Initial Pledged Stock, subject to no
pledge, lien, mortgage, hypothecation, security interest, charge, option, voting
proxy or other encumbrance whatsoever, except the existing lien and security
interest created by this Agreement; (b) it is duly organized, validly existing
and in good standing under the laws of its jurisdiction of incorporation and has
full power, authority and legal right to pledge the Initial Pledged Stock
pursuant to this Agreement; (c) this Agreement has been duly authorized,
executed and delivered by Pledgor and constitutes a legal, valid and binding
obligation of the Pledgor, and is enforceable in accordance with its terms; (d)
no consent of any other party (including, without limitation, the stockholders
or creditors of the Pledgor) and no consent, license, permit, approval or
authorization of, exemption by, notice or report to, or registration, filing or
declaration with, any Governmental Authority, domestic or foreign, is required
to be obtained by the Pledgor or the Pledgee in connection with the execution,
delivery or performance of this Agreement or the pledge of such shares
hereunder, in each case which has not been obtained or made, as the case may be,
and is not in full force and effect; (e) the execution, delivery and performance
of this Agreement will not violate any provision of any


PLEDGE AND SECURITY AGREEMENT (TIDEL TECHNOLOGIES, INC.) - Page 9


<PAGE>   10

applicable law, or of any mortgage, indenture, lease, contract, or other
agreement, instrument or undertaking to which Pledgor is a party or which
purports to be binding upon Pledgor or upon any of its assets and will not
result in the creation or imposition of any lien, charge or encumbrance on or
security interest in any of the assets of Pledgor except as contemplated by this
Agreement or the Loan Agreement; (f) all the shares of the Initial Pledged Stock
have been duly and validly issued, are fully paid and non-assessable and have
not been issued in violation of any preemptive or other rights of any person;
(g) the Pledgor has not created any options, warrants, rights, calls,
commitments, plans, contracts or other agreements of any character, which
provide for the purchase, issuance or transfer of any shares of capital stock of
Issuer pledged hereby; and (h) the pledge, assignment and delivery of such
Initial Pledged Stock pursuant to this Agreement constitutes and, provided
Pledgee retains possession of the Initial Pledged Stock, at all times
(disregarding, however the effects of the change in any law relating to the
pledge of stock generally) will constitute a valid first lien on and a first
perfected security interest in such shares of the Initial Pledged Stock, and the
proceeds thereof, subject to no prior Lien, or to any agreement purporting to
grant to any third party other than Pledgee a security interest in the property
or assets of the Pledgor which would include the Initial Pledged Stock. Pledgor
covenants and agrees that at its expense it will defend the right, title and
security interest of the Pledgee in and to the Pledged Stock and the proceeds
thereof against the claims and demands of all persons whomsoever; and covenants
and agrees that he will have like title to and right to pledge any other
property at any time hereafter pledged to the Pledgee as Collateral hereunder
and will likewise defend the right of the Pledgee thereto and security interest
therein.

         17. No Disposition. etc. Without the prior written consent of the
Pledgee, Pledgor agrees that it will not sell, assign, transfer, exchange, or
otherwise dispose of, or grant any option with respect to, the Collateral, nor
will it create, incur or permit to exist any pledge, lien, mortgage,
hypothecation, security interest, charge, option or any other encumbrance with
respect to any of the Collateral, or any interest therein, or any proceeds
thereof, except for the lien and security interest provided for by this
Agreement and except as permitted by this Agreement or by the Loan Agreement.
Without the prior written consent of the Pledgee, the Pledgor agrees that it
will not vote to enable any Issuer to issue or sell any stock or other
securities of any nature in addition to or in exchange or substitution for the
Pledged Stock or grant or issue any options, warrants, or rights of any kind to
acquire, or securities convertible into, shares of such Issuer's stock.

         18. Further Assurances. Pledgor agrees that at any time and from time
to time upon the written request of the Pledgee, the Pledgor will execute and
deliver such further documents and do such further acts and things which are
necessary in the reasonable judgment of the Pledgee to effect the purpose of
this Agreement or to obtain, maintain and perfect the security interest granted
under this Agreement in any applicable jurisdiction, and any expense of Pledgee
so incurred shall be a part of the Obligations.

         19. Severability. Any provision of this Agreement which is prohibited
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.


PLEDGE AND SECURITY AGREEMENT (TIDEL TECHNOLOGIES, INC.) - Page 10


<PAGE>   11

         20. No Waiver; Cumulative Remedies. The Pledgee shall not by any act,
delay, omission or otherwise be deemed to have waived any of its rights or
remedies hereunder and no waiver shall be valid unless in writing, signed by the
Pledgee, and then only to the extent therein set forth. A waiver by the Pledgee
of any right or remedy hereunder on any one occasion shall not be construed as a
bar to any right or remedy which Pledgee would otherwise have on any future
occasion. No failure to exercise nor any delay in exercising on the part of the
Pledgee, any right, power or privilege hereunder, shall operate as a waiver
thereof; nor shall any single or partial exercise of any right, power or
privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. The rights and remedies herein
provided are cumulative and may be exercised singly or concurrently, and are not

                          PLEDGE AND SECURITY AGREEMENT
                         (LIMITED PARTNERSHIP INTEREST)

         THIS PLEDGE AND SECURITY AGREEMENT (this "Agreement") is executed as of
the 1st day of April, 1999 by TIDEL SERVICES, INC., a Delaware corporation
("Pledgor"), in favor of CHASE BANK OF TEXAS, N.A., a national banking
association ("Pledgee").

                                    RECITALS:

         A. Tidel Engineering, L.P., a Delaware limited partnership (the
"Borrower"), Tidel Technologies, Inc. ("TTI") and Pledgee have entered into that
certain Credit Agreement dated of even date herewith (as amended, modified or
supplemented from time to time, the "Loan Agreement"), pursuant to which Pledgee
has agreed to make available to Borrower a credit facility subject to the terms
and conditions contained therein.

         B. Pledgor is the legal, record and beneficial owner of TELP
Partnership Interest (defined below).

         C. It is a condition precedent to the obligations of Pledgee under the
Loan Agreement that Pledgor shall have executed and delivered this Agreement to
Pledgee.

         D. Pledgor, by virtue of its ownership of the TELP Partnership
Interest, deems it to be in its best interest, based on sound judgment, in that
valuable benefits will be derived by the Pledgor by virtue of the Loans, to
execute and deliver to Pledgee this Agreement.

         E. In consideration of these premises and in order to induce Pledgee to
extend the credit pursuant to the Loan Agreement, and for other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the Pledgor and Pledgee hereby agree as follows:

                                   AGREEMENTS:

         1. Defined Terms. Unless otherwise defined herein, terms defined in the
Loan Agreement shall have such defined meanings when used herein.

         2. Pledge. The Pledgor hereby pledges, assigns, hypothecates, transfers
to the Pledgee, and hereby grants to Pledgee a first lien on, and security
interest in the following property whether now owned or hereafter acquired:

                  (a) all of the right, title and interest, now and hereafter
existing, of Pledgor, as a limited partner (the "TELP Partnership Interest"), in
and to the Borrower, which was formed pursuant to that certain Agreement of
Limited Partnership of Tidel Engineering, L.P. (as the same may be amended,
modified, or restated from time to time, the "TELP Partnership Agreement") dated
as of March 24, 1999;

<PAGE>   2


                  (b) any and all proceeds and distributions made pursuant to
the TELP Partnership Agreement (the "Proceeds"), due or to become due to Pledgor
under the TELP Partnership Agreement; and

                  (c) any and all present and future accounts, certificates of
deposit, securities, general intangibles, chattel paper and other proceeds
arising from, or by virtue of, or from the disposition of, or claims against any
other person or entities with respect to, all or any part of the property
described in clauses (a) or (b) preceding (all of the property described in
clauses (a), (b), and (c) being referred to collectively as the "Collateral"),

as collateral security for (i) the due and punctual payment and performance by
Pledgor of its obligations, covenants, agreements and liabilities, absolute or
contingent, liquidated or unliquidated, now existing or hereinafter incurred
under, arising out of or in connection with this Agreement, (ii) the prompt and
complete payment when due (whether at the stated due date, by acceleration or
otherwise) of the unpaid principal of and interest on the Notes issued to
evidence the Loans made by Pledgee pursuant to the Loan Agreement as well as
collection costs therefor, and (iii) the due and punctual payment and
performance of all Obligations (as defined in the Loan Agreement) by Borrower
(and any other party liable therefor) to Pledgee, absolute or contingent,
liquidated or unliquidated, now existing or hereinafter incurred (all the
foregoing being hereinafter called the "Obligations"). Notwithstanding anything
to the contrary herein, the pledge by Pledgee of any and all proceeds and
distributions made pursuant to the TELP Partnership Agreement is not intended to
prohibit any distributions permitted under the Loan Agreement.

         3. Distributions, etc. Any sums paid upon or in respect of the TELP
Partnership Interest upon the liquidation or dissolution of Borrower shall be
paid over to the Pledgee, to be held by it in trust as additional collateral
security for the Obligations; and in case any distribution of capital shall be
made on or in respect of the TELP Partnership Interest or any property shall be
distributed upon or with respect to the TELP Partnership Interest pursuant to
the recapitalization of Borrower or pursuant to the reorganization thereof, the
property so distributed shall be delivered to the Pledgee, to be held by it as
additional collateral security for the Obligations. All sums of money and
property so paid or distributed in respect of the TELP Partnership Interest
which are received by the Pledgor shall, until paid or delivered to the Pledgee,
be held by the Pledgor in trust, segregated from the other assets of the
Pledgor, as additional collateral security for the Obligations.

         4. Voting Rights. As long as an Event of Default has not occurred and
is not continuing, Pledgor shall be entitled to exercise all voting rights with
respect to the TELP Partnership Interest; provided, however, that no vote shall
be cast or consent, waiver or ratification given or action taken which would
impair the Collateral or violate any provision of this Agreement, the Loan
Agreement or the Loan Documents. After the occurrence and during the continuance
of an Event of Default, the right to vote the TELP Partnership Interest and all
other rights pertaining to the TELP Partnership Interest shall be vested
exclusively in Pledgee, including any and all rights to vote and to give
consents, waivers or ratifications with respect to the TELP Partnership Interest
as if Pledgee were the absolute owner thereof, including, without


PLEDGE AND SECURITY AGREEMENT - Page 2
(TIDEL SERVICES, INC.)

<PAGE>   3


limitation, the right to take any action to enforce the TELP Partnership
Interest, but the Pledgee shall have no duty to exercise any of the aforesaid
rights, privileges or options or be responsible for any failure to do so or
delay in so doing. To this end, Pledgor hereby irrevocably constitutes and
appoints Pledgee the attorney-in-fact of Pledgor, with full power of
substitution, to vote, and to act with respect to, the TELP Partnership Interest
standing in the name of Pledgor or with respect to which Pledgor is entitled to
vote and act, subject to the understanding that such appointment may not be
exercised unless an Event of Default has occurred and is continuing. The
appointment as attorney-in-fact herein granted is coupled with an interest, is
irrevocable, and shall continue until the Obligations have been paid and
performed in full.

         5. Limitations on Pledgee's Obligations. The Pledgee shall not be
liable for failure to collect or realize upon the Obligations or any collateral
security or guarantee therefor, or any part thereof, or for any delay in so
doing nor shall the Pledgee be under any obligation to take any action
whatsoever with regard thereto.

         6. The Pledgee's Appointment as Attorney-in-Fact. (a) In addition to,
and without limiting the scope of any other provision in this Agreement, the
Pledgor hereby irrevocably constitutes and appoints the Pledgee and any officer
or agent thereof, with full power of substitution, as its true and lawful
attorney-in-fact with full irrevocable power and authority in the place and
stead of the Pledgor and in the name of the Pledgor or in its own name, from
time to time in the Pledgee's discretion, for the purpose of carrying out the
actions and to execute any and all documents and instruments which may be
necessary or desirable to accomplish the purposes of this Agreement and, without
limiting the generality of the foregoing, hereby gives the Pledgee the power and
right, on behalf of the Pledgor, without notice to or assent by the Pledgor to
do the following upon the occurrence and during the continuance of an Event of
Default: (i) to ask, demand, collect, receive and give acquittances and receipts
for any and all monies due and to become due under the Collateral; (ii) in the
name of the Pledgor or its own name or otherwise, to take possession of and
endorse and collect any checks, drafts, notes, acceptances or other instruments
for the payment of moneys due under the Collateral; (iii) to file any claim or
to take any other action or proceeding in any court of law or equity or
otherwise deemed appropriate by the Pledgee for the purpose of collecting any
and all such moneys due under the Collateral whenever payable; (iv) to pay or
discharge taxes, liens, security interests or other encumbrances levied or
placed on or threatened against the Collateral; (v) to direct any party liable
for any payment under the Collateral to make payment of any and all moneys due
and to become due thereunder directly to the Pledgee or as the Pledgee shall
direct; (vi) to receive payment of and receipt for any and all moneys, claims
and other amounts due and to become due at any time in respect of or arising out
of any Collateral; (vii) to commence and prosecute any suits, actions or
proceedings at law or in equity in any court of competent jurisdiction to
collect the Collateral or any part thereof and to enforce any other right in
respect of the Collateral; (viii) to defend any suit, action or proceeding
brought against the Pledgor with respect to any Collateral; (ix) to settle,
compromise or adjust any suit, action or proceeding described above and, in
connection therewith, to give such discharges or releases as the Pledgee may
deem appropriate; (x) exercise voting rights attributable to the TELP
Partnership Interest pursuant to SECTION 4; and (xi) generally to sell,
transfer, pledge, make any agreement with respect to or otherwise deal with any
of the Collateral as fully and completely as though the

Pledgee were the absolute owner thereof for all purposes, and to do, at the
Pledgee's option and the Pledgor's expense, at any time, or from time to time,
all acts and things which the Pledgee deems necessary to protect, preserve or
realize upon the Collateral and the Pledgee's security interest therein, in
order to effect the intent of this Agreement, all as fully and effectively as
the Pledgor might do.

         The Pledgor hereby ratifies all that said attorneys shall lawfully do
or cause to be done by virtue hereof. This power of attorney is a power coupled
with an interest and shall be irrevocable.

                  (b) The powers conferred on the Pledgee hereunder are solely
to protect its interests in the Collateral and shall not impose any duty upon it
to exercise any such powers. Pledgee shall be accountable only for amounts that
it actually receives as a result of the exercise of such powers and neither it
nor any of its officers, directors, employees or agents shall be responsible to
the Pledgor for any act or failure to act.

                  (c) The Pledgor also authorizes the Pledgee, at any time and
from time to time, to execute, in connection with any sale of the Collateral,
any endorsements, assignments or other instruments of conveyance or transfer
with respect to the Collateral.

         7. Performance by the Pledgee of the Pledgor's Obligations. If the
Pledgor fails to perform or comply with any of its agreements contained herein
and the Pledgee, as provided for by the terms of this Agreement, shall itself
perform or comply, or otherwise cause performance or compliance, with such
agreement, then the expenses of the Pledgee incurred in connection with such
performance or compliance, together with interest thereon to accrue at a rate of
interest equal to the Highest Lawful Rate from the date such expenses are
incurred, shall be payable by the Pledgor to the Pledgee on demand and shall
constitute Obligations secured hereby.

         8. Events of Default. The occurrence of any of the following shall
constitute an "Event of Default" under this Agreement:

                  (a) The Pledgor shall fail to pay its Obligations when due;

                  (b) Any representation, warranty or statement made or deemed
made by the Pledgor herein or in connection herewith shall prove to have been
incorrect or untrue in any material respect on or as of the date made or deemed
made;

                  (c) The Pledgor shall default in the observance or performance
of any term, covenant, or agreement contained herein and Pledgor shall fail to
cure such default within fifteen (15) days after the occurrence of such default;
or

                  (d) An Event of Default (subject to any applicable cure
period), as such term is defined in the Loan Agreement, shall occur and be
continuing.

         9. Remedies. (a) Upon the occurrence and during the continuance of any
Event of Default, and at any time thereafter, the Pledgee may declare all of the
Obligations or any part thereof immediately due and payable and, without demand
of performance or other demand, advertisement or notice of any kind (except the
notice specified below of time and place of public or private sale) to or upon
the Pledgor or any other person (all and each of which demands, advertisements
and/or notices are hereby expressly waived), may forthwith collect, receive,
appropriate and realize upon the Collateral, or any part thereof, and/or may
forthwith sell, assign, give option or options to purchase, contract to sell or
otherwise dispose of and deliver said Collateral, or any part thereof, in one or
more parcels at public or private sale or sales, at any exchange, broker's board
or at the Pledgee's offices or elsewhere upon such terms and conditions as it
may deem advisable and at such prices as it may deem best, for cash or on credit
or for future delivery without assumption of any credit risk, with the right to
the Pledgee upon any such sale or sales, public or private, to purchase the
whole or any part of said Collateral so sold, free of any right or equity of
redemption in the Pledgor, which right or equity is hereby expressly waived or
released. The Pledgee shall apply the net proceeds of any such collection,
recovery, receipt, appropriation, realization or sale, after deducting all
reasonable costs and expenses of every kind incurred therein or incidental to
the care, safekeeping or otherwise of any and all of the Collateral or in any
way relating to the rights of the Pledgee hereunder, including reasonable
attorneys' fees and legal expenses, to the payment in whole or in part of the
Obligations in such order as the Pledgee may elect, the Pledgor remaining liable
for any deficiency remaining unpaid after such application, and only after so
applying such net proceeds and after the payment by the Pledgee of any amount
required by any provision of law, including, without limitation, Section 9-504
(a) (3) of the Uniform Commercial Code of the State of Texas (the "Code"), need
the Pledgee account for the surplus, if any, to the Pledgor. The Pledgor agrees
that, to the extent permitted by law, the Pledgee need not give more than ten
(10) days' notice of the time and place of any public sale or of the time after
which a private sale or other intended disposition is to take place and that
such notice is reasonable notification of such matters. No notification need be
given to the Pledgor if it has signed after default a statement renouncing or
modifying any right to notification of sale or other intended disposition. IN
ADDITION TO THE RIGHTS AND REMEDIES GRANTED TO IT IN THIS AGREEMENT AND IN ANY
OTHER INSTRUMENT OR AGREEMENT SECURING, EVIDENCING OR RELATING TO ANY OF THE
OBLIGATIONS, THE PLEDGEE SHALL HAVE ALL THE RIGHTS AND REMEDIES OF A SECURED
PARTY UNDER THE CODE. All waivers by the Pledgor of rights (including rights to
notice) and all rights and remedies afforded the Pledgor herein, and all other
provisions of this Agreement, are expressly made subject to any applicable
mandatory provisions of law limiting, or imposing conditions (including
conditions as to reasonableness) upon such waivers of the effectiveness thereof
or any such rights and remedies. Any sale or other disposition of the Collateral
shall be in compliance with all provisions of law (including applicable
securities laws, and regulations and applicable provisions of the Code).

                  (b) If Pledgee shall determine to exercise its right to sell
any or all of the TELP Partnership Interest pursuant to this SECTION 9 hereof,
and if in the opinion of counsel for Pledgee it is advisable to have the TELP
Partnership Interest, or that portion thereof to be sold, registered under the
provisions of the Securities Act of 1933, as amended (the "Securities Act"),


PLEDGE AND SECURITY AGREEMENT - Page 5
(TIDEL SERVICES, INC.)

<PAGE>   6


the Pledgor will cause the Borrower to execute and deliver, and cause the
general partner thereof to execute and deliver, all at the Pledgor's expense,
all such instruments and documents, and to do or cause to be done all such other
acts and things as may be necessary to register the TELP Partnership Interest,
or that portion thereof to be sold, under the provisions of the Securities Act
and to cause the registration statement relating thereto to become effective and
to remain effective for a period of 180 days from the date of the first public
offering of the TELP Partnership Interest, or that portion thereof to be sold,
and to make all amendments thereto and/or to the related prospectus which are
necessary, all in conformity with the requirements of the Securities Act and the
rules and regulations of the Securities and Exchange Commission applicable
thereto. The Pledgor agrees to cause Borrower to comply with the provisions of
the securities or "Blue Sky" laws of any jurisdiction which Pledgee shall
designate and to cause Borrower to make available to its security holders, as
soon as practicable, an earnings statement which will satisfy the provisions of
Section 11(a) of the Securities Act.

                  (c) The Pledgor recognizes that the Pledgee may be unable to
effect a public sale of any or all the TELP Partnership Interest by reason of
certain prohibitions contained in the Securities Act and applicable state
securities laws, but may be compelled to resort to one or more private sales
thereof to a restricted group of purchasers who will be obliged to agree, among
other things, to acquire such securities for their own account for investment
and not with a view to the distribution or resale thereof. The Pledgor
acknowledges and agrees that any such private sale may result in prices and
other terms less favorable to the seller than if such sale were a public sale
and, notwithstanding such circumstances, agrees that any such private sale shall
be deemed to have been made in a commercially reasonable manner. Pledgee shall
be under no obligation to delay a sale of any of the TELP Partnership Interest
for the period of time necessary to permit the Borrower to register such
securities for public sale under the Securities Act, or under applicable state
securities laws, even if the Borrower would agree to do so.

                  (d) The Pledgor further agrees to do or cause to be done all
such other acts and things as may be necessary to make such sale or sales of any
portion of all of the TELP Partnership Interest valid and binding and in
compliance with any and all applicable laws, regulations, orders, writs,
injunctions, decrees or awards of any and all courts, arbitrators or
governmental instrumentalities, domestic or foreign, having jurisdiction over
any such sale or sales, all at the Pledgor's expense. The Pledgor further agrees
that a breach of any of the covenants contained in this SECTION 9 will cause
irreparable injury to Pledgee, that Pledgee has no adequate remedy at law in
respect of such breach and, as a consequence, agrees that each and every
covenant contained in this paragraph shall be specifically enforceable against
the Pledgor and the Pledgor hereby waives and agrees not to assert any defenses
against an action for specific performance of such covenants except for a
defense that no default of the covenants, terms or conditions of the Loan
Agreement has occurred. The Pledgor further acknowledges the impossibility of
ascertaining the amount of damages which would be suffered by Pledgee by reason
of a breach of any such covenants and, consequently, agrees that, if Pledgee
shall sue for damages for breach, Pledgor shall pay, as liquidated damages and
not as a penalty, an amount equal to the value of the TELP Partnership Interest
on the date Pledgee shall demand compliance with this paragraph, but in no event
to exceed the amount of the Obligations.


PLEDGE AND SECURITY AGREEMENT - Page 6

<PAGE>   7


         10. Waiver of Subrogation. Notwithstanding anything to the contrary in
this Agreement, unless and until the Obligations have been indefeasibly paid and
performed in full, the Pledgor hereby irrevocably waives all rights Pledgor may
have at law or in equity (including, without limitation, any law subrogating the
Pledgor to the rights of the Pledgee) to seek contribution, indemnification, or
any other form of reimbursement from the Borrower, any other guarantor or
pledgor, or any other person now or hereafter primarily or secondarily liable
for any obligations of the Borrower to the Pledgee, for any disbursement made by
the Pledgor under or in connection with this Agreement or otherwise. The Pledgor
further agrees that, to the extent that the waiver of any such subrogation,
contribution, reimbursement, indemnity or otherwise is found to be void or
voidable for any reason, any such rights which the Pledgor may have shall be
junior and subordinate in all respects to the rights of the Pledgee against the
Borrower.

         11. Actions by Pledgee. No action that the Pledgee may take or omit to
take in connection with the Loan Agreement or any of the Loan Documents, any
indebtedness owing by Borrower to the Pledgee (including, without limitation,
renewals, extensions, modifications and increases thereof), or any security for
the payment of any indebtedness of Borrower to the Pledgee, or for the
performance of any obligation or undertaking of Borrower, nor any course of
dealing with Borrower or any other Person, shall release the Pledgor from his
obligations hereunder, affect this Agreement in any way, or afford the Pledgor
any recourse against the Pledgee. By way of example, but not in limitation of
the foregoing, the Pledgor hereby expressly agrees that the Pledgee may, from
time to time, without notice to the Pledgor:

                  (a) sell, assign, transfer or grant participations in the
Loans and/or any right held by the Pledgee pursuant to or in connection with the
Loan Agreement and the Loan Documents;

                  (b) amend, change, or modify, in whole or in part, any
documents or instruments evidencing, securing or relating to any indebtedness or
undertaking of Borrower or TTI to the Pledgee;

                  (c) accelerate, change, extend, or renew the time for payment
of the Notes or any other indebtedness arising under any documents or
instruments evidencing, securing or relating to any indebtedness or undertaking
of Borrower or TTI to the Pledgee;

                  (d) compromise or settle any amount due or owing, or claimed
to be due or owing, under the Notes or under any documents or instruments
evidencing, securing or relating to any indebtedness or undertaking of Borrower
or TTI to the Pledgee;

                  (e) surrender, release, or subordinate any or all security for
any indebtedness or undertaking of Borrower or TTI to the Pledgee or accept
additional or substituted security therefor;

                  (f) release any guarantor or pledgor of any indebtedness or
undertaking of the Borrower or TTI to the Pledgee, or substitute or add
additional guarantors or pledgors; and

(TIDEL SERVICES, INC.)

<PAGE>   8


                  (g) apply collateral securing the Notes to other indebtedness
also secured by such collateral.

The provisions of this Agreement shall extend and be applicable to all renewals,
increases, amendments, extensions, modifications of and substitutions for the
Loan Agreement and the Loan Documents, and all references herein to the Loan
Agreement and the Loan Documents shall be deemed to include any renewal,
increase, extension, amendment or modification thereof or substitution therefor.

         12. No Impairment. The obligations, guaranties, undertakings,
covenants, agreements and duties of the Pledgor under this Agreement shall not
be affected or impaired by any of the following, although without notice to or
consent of the Pledgor:

                  (a) any failure, omission or delay on the part of the Pledgee
(i) to enforce, assert or exercise any right, power or remedy conferred on the
Pledgee by the provisions of the Loan Agreement and the Loan Documents or
otherwise inuring to the holders of the rights of the Pledgee under the Loan
Agreement and the Loan Documents, or (ii) to make demand first upon Borrower or
TTI or to proceed against Borrower or TTI;

                  (b) the voluntary or involuntary liquidation, dissolution,
sale of all or substantially all assets, marshalling of assets or liabilities,
receivership, conservatorship, assignment for the benefit of creditors,
insolvency, bankruptcy, reorganization, arrangement, composition or other
proceedings under laws for the protection of debtors affecting Borrower or TTI
or any of the assets of Borrower or TTI, or any discharge from liability or
rejection of burdensome contracts or obligations in the course of or resulting
from any such proceedings;

                  (c) the release, by operation of law or otherwise, of Borrower
or TTI or any guarantor from any obligation under the Loan Agreement or any of
the Loan Documents;

                  (d) the invalidity, deficiency, illegality or unenforceability
of the Loan Agreement and the Loan Documents, in whole or in part, or of any of
the provisions thereof, or failure to perfect or maintain perfection of any
security, or any defense or excuse for failure to perform on account of force
majeure, act of God, casualty, impossibility, impracticability, or other defense
or excuse whatsoever; or

                  (e) without limiting the foregoing, any fact or event (whether
or not similar to any of the foregoing) which in the absence of this provision
would or might constitute or afford a legal or equitable discharge or release of
or defense to a guarantor or surety.

None of the foregoing shall be a defense to this Agreement, and this Agreement
is a primary obligation of the Pledgor.

         13. Other Pledgors or Guarantors. The liabilities and obligations of
the Pledgor hereunder shall not be reduced or limited by reason of any guaranty
or pledge executed in favor

of the Pledgee by any other Person, and this Agreement shall be enforceable
against the Pledgor without regard to any such guaranty or pledge.

         14. Representations, Warranties and Covenants of the Pledgor. The
Pledgor represents and warrants that:

                  (a) it is the legal, record and beneficial owner of, and has
good and, subject to applicable securities laws described in SECTION 9 hereof,
marketable title to, the TELP Partnership Interest, subject to no pledge, lien,
mortgage, hypothecation, security interest, charge, option, or other encumbrance
whatsoever, except the existing lien and security interest created by this
Agreement;

                  (b) it is duly organized, validly existing and in good
standing under the laws of its jurisdiction of incorporation and has full power,
authority and legal right to pledge the TELP Partnership Interest pursuant to
this Agreement;

                  (c) this Agreement has been duly authorized, executed and
delivered by Pledgor and constitutes a legal, valid and binding obligation of
the Pledgor, and is enforceable in accordance with its terms;

                  (d) other than the approvals, if any, required under the TELP
Partnership Agreement, no consent of any other party (including, without
limitation, the stockholders or creditors of the Pledgor) and no consent,
license, permit, approval or authorization of, exemption by, notice or report
to, or registration, filing or declaration with, any Governmental Authority,
domestic or foreign, is required to be obtained by the Pledgor or the Pledgee in
connection with the execution, delivery or performance of this Agreement or the
pledge of the TELP Partnership Interest hereunder, in each case which has not
been obtained or made, as the case may be, and is not in full force and effect;

                  (e) the execution, delivery and performance of this Agreement
will not violate any provision of any applicable law, or of any mortgage,
indenture, lease, contract, or other agreement, instrument or undertaking to
which Pledgor is a party or which purports to be binding upon Pledgor or upon
any of its assets and will not result in the creation or imposition of any lien,
charge or encumbrance on or security interest in any of the assets of Pledgor
except as contemplated by this Agreement or the Loan Agreement;

                  (f) the TELP Partnership Interest is not a security, as
defined in Article 8 of the Texas Business and Commerce Code; and

                  (g) the pledge and assignment of the Collateral pursuant to
this Agreement constitutes and will constitute a valid first lien on and a first
perfected security interest in the Collateral, and the proceeds thereof, subject
to no prior Lien, or to any agreement purporting to grant to any third party
other than Pledgee a security interest in the property or assets of the Pledgor
which would include the Collateral.

                  Pledgor covenants and agrees (a) that at its expense it will
defend the right, title and security interest of the Pledgee in and to the
Collateral against the claims and demands of all persons whomsoever;

                  (b) that it will have like title to and right to pledge any
other property at any time hereafter pledged to the Pledgee as Collateral
hereunder and will likewise defend the right of the Pledgee thereto and security
interest therein;

                  (c) to observe, perform and discharge all obligations,
covenants and warranties provided for under the terms of the TELP Partnership
Agreement to be kept, observed and performed by Pledgor, and to inform Pledgee
promptly in writing of any notice received by Pledgor: (i) with respect to any
obligation to be performed but alleged not to have been performed by Pledgor
under the TELP Partnership Agreement; and (ii) of any default or claimed default
by any party to the TELP Partnership Agreement;

                  (d) to enforce or secure the enforcement, in the name of
Pledgee, of the performance of each and every obligation, term, covenant,
condition and agreement to be performed by any other party under the terms of
the TELP Partnership Agreement;

                  (e) not to vote in favor of, or cause, the termination of the
Borrower, or vote in favor of any modification, extension, renewal, amendment or
material alteration of any term of the TELP Partnership Agreement without, in
each such instance, the prior written consent of Pledgee; and

                  (f) that Pledgee, after the occurrence of an Event of Default,
without notice to Pledgor, shall have the right at any time and from time to
time to notify and direct the general partner, or such other appropriate party,
of the Borrower to thereafter make all disbursements of the Proceeds directly to
Pledgee; such general partner or other party shall be fully protected in relying
on the written statement of Pledgee that it holds a security interest that
entitles Pledgee to receive any such disbursement, and the receipt by Pledgee of
such disbursements shall be full acquittance thereof to the party making such
disbursements.

         15. No Disposition. Without the prior written consent of the Pledgee,
Pledgor agrees that it will not sell, assign, transfer, exchange, or otherwise
dispose of, or grant any option with respect to, the Collateral, nor will it
create, incur or permit to exist any pledge, lien, mortgage, hypothecation,
security interest, charge, option or any other encumbrance with respect to any
of the Collateral, or any interest therein, or any proceeds thereof, except for
the lien and security interest provided for by this Agreement and except as
permitted by this Agreement or by the Loan Agreement.

         16. Further Assurances. Pledgor agrees that at any time and from time
to time upon the written request of the Pledgee, the Pledgor will execute and
deliver such further documents and do such further acts and things which are
necessary in the reasonable judgment of the Pledgee to effect the purpose of
this Agreement or to obtain, maintain and perfect the security

<PAGE>   11


interest granted under this Agreement in any applicable jurisdiction, and any
expense of Pledgee so incurred shall be a part of the Obligations.

         17. Severability. Any provision of this Agreement which is prohibited
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

         18. No Waiver; Cumulative Remedies. The Pledgee shall not by any act,
delay, omission or otherwise be deemed to have waived any of its rights or
remedies hereunder and no waiver shall be valid unless in writing, signed by the
Pledgee, and then only to the extent therein set forth. A waiver by the Pledgee
of any right or remedy hereunder on any one occasion shall not be construed as a
bar to any right or remedy which Pledgee would otherwise have on any future
occasion. No failure to exercise nor any delay in exercising on the part of the
Pledgee, any right, power or privilege hereunder, shall operate as a waiver
thereof; nor shall any single or partial exercise of any right, power or
privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. The rights and remedies herein
provided are cumulative and may be exercised singly or concurrently, and are not
exclusive of any rights or remedies provided by law.

         19. Waivers, Amendments, Entirety. None of the terms or provisions of
this Agreement may be waived, altered, modified or amended except by an
instrument in writing, duly executed by the Pledgee. This Agreement and all
obligations of the Pledgor hereunder shall be binding upon the successors and
assigns of the Pledgor, and shall, together with the rights and remedies of
Pledgee hereunder, inure to the benefit of Pledgee and its successors and
assigns. THIS AGREEMENT REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES
HERETO 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.

         20. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND BE
CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS
WITHOUT GIVING EFFECT TO THE CHOICE OF LAWS RULES THEREOF.

         21. Counterparts. This Agreement may be executed in any number of
counterparts and by the different parties on separate counterparts and each such
counterpart shall be deemed to be an original, but all such counterparts shall
together constitute one and the same Agreement.

         22. Reinstatement. This Agreement shall remain in full force and effect
and continue to be effective should any petition be filed by or against the
Pledgor, Borrower or TTI for liquidation or reorganization, should the Pledgor,
Borrower or TTI become insolvent or make an assignment for the benefit of
creditors or should a receiver or trustee be appointed for all or any
significant part of the Pledgor's assets or the assets of Borrower or TTI and
shall continue to be

effective or be reinstated, as the case may be, if at any time payment and
performance of the Obligations, or any part thereof is, pursuant to applicable
law, rescinded or reduced in amount, or must otherwise be restored or returned
by any obligee of the Obligations, whether as a "voidable preference",
"fraudulent conveyance", or otherwise, all as though such payment or performance
had not been made. In the event that any payment, or any part thereof, is
rescinded, reduced, restored or returned, the Obligations shall be reinstated
and deemed reduced only by such amount and not so rescinded, reduced, restored
or returned.

         IN WITNESS WHEREOF, Pledgor has caused this Agreement to be duly
executed and delivered as of the day and year first above written.

                          PLEDGE AND SECURITY AGREEMENT
                         (GENERAL PARTNERSHIP INTEREST)


         THIS PLEDGE AND SECURITY AGREEMENT (this "Agreement") is executed as of
the 1st day of April, 1999 by TIDEL CASH SYSTEMS, INC., a Delaware corporation
("Pledgor"), in favor of CHASE BANK OF TEXAS, N.A., a national banking
association ("Pledgee").

                                    RECITALS:

         A. Tidel Engineering, L.P., a Delaware limited partnership (the
"Borrower"), Tidel Technologies, Inc. ("TTI") and Pledgee have entered into that
certain Credit Agreement dated of even date herewith (as amended, modified or
supplemented from time to time, the "Loan Agreement"), pursuant to which Pledgee
has agreed to make available to Borrower a credit facility subject to the terms
and conditions contained therein.

         B. Pledgor is the legal, record and beneficial owner of TELP
Partnership Interest (defined below).

         C. It is a condition precedent to the obligations of Pledgee under the
Loan Agreement that Pledgor shall have executed and delivered this Agreement to
Pledgee.

         D. Pledgor, by virtue of its ownership of the TELP Partnership
Interest, deems it to be in its best interest, based on sound judgment, in that
valuable benefits will be derived by the Pledgor by virtue of the Loans, to
execute and deliver to Pledgee this Agreement.

         E. In consideration of these premises and in order to induce Pledgee to
extend the credit pursuant to the Loan Agreement, and for other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the Pledgor and Pledgee hereby agree as follows:

                                   AGREEMENTS:

         1. Defined Terms. Unless otherwise defined herein, terms defined in the
Loan Agreement shall have such defined meanings when used herein.

         2. Pledge. The Pledgor hereby pledges, assigns, hypothecates, transfers
to the Pledgee, and hereby grants to Pledgee a first lien on, and security
interest in the following property whether now owned or hereafter acquired:

                  (a) all of the right, title and interest, now and hereafter
existing, of Pledgor, as a general partner (the "TELP Partnership Interest"), in
and to the Borrower, which was formed pursuant to that certain Agreement of
Limited Partnership of Tidel Engineering, L.P. (as the

same may be amended, modified, or restated from time to time, the "TELP
Partnership Agreement") dated as of March 24, 1999;

                  (b) any and all proceeds and distributions made pursuant to
the TELP Partnership Agreement (the "Proceeds"), due or to become due to Pledgor
under the TELP Partnership Agreement; and

                  (c) any and all present and future accounts, certificates of
deposit, securities, general intangibles, chattel paper and other proceeds
arising from, or by virtue of, or from the disposition of, or claims against any
other person or entities with respect to, all or any part of the property
described in clauses (a) or (b) preceding (all of the property described in
clauses (a), (b), and (c) being referred to collectively as the "Collateral"),

as collateral security for (i) the due and punctual payment and performance by
Pledgor of its obligations, covenants, agreements and liabilities, absolute or
contingent, liquidated or unliquidated, now existing or hereinafter incurred
under, arising out of or in connection with this Agreement, (ii) the prompt and
complete payment when due (whether at the stated due date, by acceleration or
otherwise) of the unpaid principal of and interest on the Notes issued to
evidence the Loans made by Pledgee pursuant to the Loan Agreement as well as
collection costs therefor, and (iii) the due and punctual payment and
performance of all Obligations (as defined in the Loan Agreement) by Borrower
(and any other party liable therefor) to Pledgee, absolute or contingent,
liquidated or unliquidated, now existing or hereinafter incurred (all the
foregoing being hereinafter called the "Obligations"). Notwithstanding anything
to the contrary herein, the pledge by Pledgee of any and all proceeds and
distributions made pursuant to the TELP Partnership Agreement is not intended to
prohibit any distributions permitted under the Loan Agreement.

         3. Distributions, etc. Any sums paid upon or in respect of the TELP
Partnership Interest upon the liquidation or dissolution of Borrower shall be
paid over to the Pledgee, to be held by it in trust as additional collateral
security for the Obligations; and in case any distribution of capital shall be
made on or in respect of the TELP Partnership Interest or any property shall be
distributed upon or with respect to the TELP Partnership Interest pursuant to
the recapitalization of Borrower or pursuant to the reorganization thereof, the
property so distributed shall be delivered to the Pledgee, to be held by it as
additional collateral security for the Obligations. All sums of money and
property so paid or distributed in respect of the TELP Partnership Interest
which are received by the Pledgor shall, until paid or delivered to the Pledgee,
be held by the Pledgor in trust, segregated from the other assets of the
Pledgor, as additional collateral security for the Obligations.

         4. Voting Rights. As long as an Event of Default has not occurred and
is not continuing, Pledgor shall be entitled to exercise all voting rights with
respect to the TELP Partnership Interest; provided, however, that no vote shall
be cast or consent, waiver or ratification given or action taken which would
impair the Collateral or violate any provision of this Agreement, the Loan
Agreement or the Loan Documents. After the occurrence and during the continuance
of an Event of Default, the right to vote the TELP Partnership Interest and all


PLEDGE AND SECURITY AGREEMENT - Page 2
(TIDEL CASH SYSTEMS, INC.)

<PAGE>   3


other rights pertaining to the TELP Partnership Interest shall be vested
exclusively in Pledgee, including any and all rights to vote and to give
consents, waivers or ratifications with respect to the TELP Partnership Interest
as if Pledgee were the absolute owner thereof, including, without limitation,
the right to take any action to enforce the TELP Partnership Interest, but the
Pledgee shall have no duty to exercise any of the aforesaid rights, privileges
or options or be responsible for any failure to do so or delay in so doing. To
this end, Pledgor hereby irrevocably constitutes and appoints Pledgee the
attorney-in-fact of Pledgor, with full power of substitution, to vote, and to
act with respect to, the TELP Partnership Interest standing in the name of
Pledgor or with respect to which Pledgor is entitled to vote and act, subject to
the understanding that such appointment may not be exercised unless an Event of
Default has occurred and is continuing. The appointment as attorney-in-fact
herein granted is coupled with an interest, is irrevocable, and shall continue
until the Obligations have been paid and performed in full.

         5. Limitations on Pledgee's Obligations. The Pledgee shall not be
liable for failure to collect or realize upon the Obligations or any collateral
security or guarantee therefor, or any part thereof, or for any delay in so
doing nor shall the Pledgee be under any obligation to take any action
whatsoever with regard thereto.

         6. The Pledgee's Appointment as Attorney-in-Fact. (a) In addition to,
and without limiting the scope of any other provision in this Agreement, the
Pledgor hereby irrevocably constitutes and appoints the Pledgee and any officer
or agent thereof, with full power of substitution, as its true and lawful
attorney-in-fact with full irrevocable power and authority in the place and
stead of the Pledgor and in the name of the Pledgor or in its own name, from
time to time in the Pledgee's discretion, for the purpose of carrying out the
actions and to execute any and all documents and instruments which may be
necessary or desirable to accomplish the purposes of this Agreement and, without
limiting the generality of the foregoing, hereby gives the Pledgee the power and
right, on behalf of the Pledgor, without notice to or assent by the Pledgor to
do the following upon the occurrence and during the continuance of an Event of
Default: (i) to ask, demand, collect, receive and give acquittances and receipts
for any and all monies due and to become due under the Collateral; (ii) in the
name of the Pledgor or its own name or otherwise, to take possession of and
endorse and collect any checks, drafts, notes, acceptances or other instruments
for the payment of moneys due under the Collateral; (iii) to file any claim or
to take any other action or proceeding in any court of law or equity or
otherwise deemed appropriate by the Pledgee for the purpose of collecting any
and all such moneys due under the Collateral whenever payable; (iv) to pay or
discharge taxes, liens, security interests or other encumbrances levied or
placed on or threatened against the Collateral; (v) to direct any party liable
for any payment under the Collateral to make payment of any and all moneys due
and to become due thereunder directly to the Pledgee or as the Pledgee shall
direct; (vi) to receive payment of and receipt for any and all moneys, claims
and other amounts due and to become due at any time in respect of or arising out
of any Collateral; (vii) to commence and prosecute any suits, actions or
proceedings at law or in equity in any court of competent jurisdiction to
collect the Collateral or any part thereof and to enforce any other right in
respect of the Collateral; (viii) to defend any suit, action or proceeding
brought against the Pledgor with respect to any Collateral; (ix) to settle,
compromise or adjust any suit, action or proceeding described above and, in
connection therewith, to give such discharges or releases as the Pledgee


PLEDGE AND SECURITY AGREEMENT - Page 3
(TIDEL CASH SYSTEMS, INC.)

<PAGE>   4


may deem appropriate; (x) exercise voting rights attributable to the TELP
Partnership Interest pursuant to SECTION 4; and (xi) generally to sell,
transfer, pledge, make any agreement with respect to or otherwise deal with any
of the Collateral as fully and completely as though the Pledgee were the
absolute owner thereof for all purposes, and to do, at the Pledgee's option and
the Pledgor's expense, at any time, or from time to time, all acts and things
which the Pledgee deems necessary to protect, preserve or realize upon the
Collateral and the Pledgee's security interest therein, in order to effect the
intent of this Agreement, all as fully and effectively as the Pledgor might do.

         The Pledgor hereby ratifies all that said attorneys shall lawfully do
or cause to be done by virtue hereof. This power of attorney is a power coupled
with an interest and shall be irrevocable.

                  (b) The powers conferred on the Pledgee hereunder are solely
to protect its interests in the Collateral and shall not impose any duty upon it
to exercise any such powers. Pledgee shall be accountable only for amounts that
it actually receives as a result of the exercise of such powers and neither it
nor any of its officers, directors, employees or agents shall be responsible to
the Pledgor for any act or failure to act.

                  (c) The Pledgor also authorizes the Pledgee, at any time and
from time to time, to execute, in connection with any sale of the Collateral,
any endorsements, assignments or other instruments of conveyance or transfer
with respect to the Collateral.

         7. Performance by the Pledgee of the Pledgor's Obligations. If the
Pledgor fails to perform or comply with any of its agreements contained herein
and the Pledgee, as provided for by the terms of this Agreement, shall itself
perform or comply, or otherwise cause performance or compliance, with such
agreement, then the expenses of the Pledgee incurred in connection with such
performance or compliance, together with interest thereon to accrue at a rate of
interest equal to the Highest Lawful Rate from the date such expenses are
incurred, shall be payable by the Pledgor to the Pledgee on demand and shall
constitute Obligations secured hereby.

         8. Events of Default. The occurrence of any of the following shall
constitute an "Event of Default" under this Agreement:

                  (a) The Pledgor shall fail to pay its Obligations when due;

                  (b) Any representation, warranty or statement made or deemed
made by the Pledgor herein or in connection herewith shall prove to have been
incorrect or untrue in any material respect on or as of the date made or deemed
made;

                  (c) The Pledgor shall default in the observance or performance
of any term, covenant, or agreement contained herein and Pledgor shall fail to
cure such default within fifteen (15) days after the occurrence of such default;
or


PLEDGE AND SECURITY AGREEMENT - Page 4
(TIDEL CASH SYSTEMS, INC.)

<PAGE>   5


                  (d) An Event of Default (subject to any applicable cure
period), as such term is defined in the Loan Agreement, shall occur and be
continuing.

         9. Remedies. (a) Upon the occurrence and during the continuance of any
Event of Default, and at any time thereafter, the Pledgee may declare all of the
Obligations or any part thereof immediately due and payable and, without demand
of performance or other demand, advertisement or notice of any kind (except the
notice specified below of time and place of public or private sale) to or upon
the Pledgor or any other person (all and each of which demands, advertisements
and/or notices are hereby expressly waived), may forthwith collect, receive,
appropriate and realize upon the Collateral, or any part thereof, and/or may
forthwith sell, assign, give option or options to purchase, contract to sell or
otherwise dispose of and deliver said Collateral, or any part thereof, in one or
more parcels at public or private sale or sales, at any exchange, broker's board
or at the Pledgee's offices or elsewhere upon such terms and conditions as it
may deem advisable and at such prices as it may deem best, for cash or on credit
or for future delivery without assumption of any credit risk, with the right to
the Pledgee upon any such sale or sales, public or private, to purchase the
whole or any part of said Collateral so sold, free of any right or equity of
redemption in the Pledgor, which right or equity is hereby expressly waived or
released. The Pledgee shall apply the net proceeds of any such collection,
recovery, receipt, appropriation, realization or sale, after deducting all
reasonable costs and expenses of every kind incurred therein or incidental to
the care, safekeeping or otherwise of any and all of the Collateral or in any
way relating to the rights of the Pledgee hereunder, including reasonable
attorneys' fees and legal expenses, to the payment in whole or in part of the
Obligations in such order as the Pledgee may elect, the Pledgor remaining liable
for any deficiency remaining unpaid after such application, and only after so
applying such net proceeds and after the payment by the Pledgee of any amount
required by any provision of law, including, without limitation, Section 9-504
(a) (3) of the Uniform Commercial Code of the State of Texas (the "Code"), need
the Pledgee account for the surplus, if any, to the Pledgor. The Pledgor agrees
that, to the extent permitted by law, the Pledgee need not give more than ten
(10) days' notice of the time and place of any public sale or of the time after
which a private sale or other intended disposition is to take place and that
such notice is reasonable notification of such matters. No notification need be
given to the Pledgor if it has signed after default a statement renouncing or
modifying any right to notification of sale or other intended disposition. IN
ADDITION TO THE RIGHTS AND REMEDIES GRANTED TO IT IN THIS AGREEMENT AND IN ANY
OTHER INSTRUMENT OR AGREEMENT SECURING, EVIDENCING OR RELATING TO ANY OF THE
OBLIGATIONS, THE PLEDGEE SHALL HAVE ALL THE RIGHTS AND REMEDIES OF A SECURED
PARTY UNDER THE CODE. All waivers by the Pledgor of rights (including rights to
notice) and all rights and remedies afforded the Pledgor herein, and all other
provisions of this Agreement, are expressly made subject to any applicable
mandatory provisions of law limiting, or imposing conditions (including
conditions as to reasonableness) upon such waivers of the effectiveness thereof
or any such rights and remedies. Any sale or other disposition of the Collateral
shall be in compliance with all provisions of law (including applicable
securities laws, and regulations and applicable provisions of the Code).

                  (b) If Pledgee shall determine to exercise its right to sell
any or all of the TELP Partnership Interest pursuant to this SECTION 9 hereof,
and if in the opinion of counsel for Pledgee it is advisable to have the TELP
Partnership Interest, or that portion thereof to be sold, registered under the
provisions of the Securities Act of 1933, as amended (the "Securities Act"), the
Pledgor will cause the Borrower to execute and deliver, and cause the general
partner thereof to execute and deliver, all at the Pledgor's expense, all such
instruments and documents, and to do or cause to be done all such other acts and
things as may be necessary to register the TELP Partnership Interest, or that
portion thereof to be sold, under the provisions of the Securities Act and to
cause the registration statement relating thereto to become effective and to
remain effective for a period of 180 days from the date of the first public
offering of the TELP Partnership Interest, or that portion thereof to be sold,
and to make all amendments thereto and/or to the related prospectus which are
necessary, all in conformity with the requirements of the Securities Act and the
rules and regulations of the Securities and Exchange Commission applicable
thereto. The Pledgor agrees to cause Borrower to comply with the provisions of
the securities or "Blue Sky" laws of any jurisdiction which Pledgee shall
designate and to cause Borrower to make available to its security holders, as
soon as practicable, an earnings statement which will satisfy the provisions of
Section 11(a) of the Securities Act.

                  (c) The Pledgor recognizes that the Pledgee may be unable to
effect a public sale of any or all the TELP Partnership Interest by reason of
certain prohibitions contained in the Securities Act and applicable state
securities laws, but may be compelled to resort to one or more private sales
thereof to a restricted group of purchasers who will be obliged to agree, among
other things, to acquire such securities for their own account for investment
and not with a view to the distribution or resale thereof. The Pledgor
acknowledges and agrees that any such private sale may result in prices and
other terms less favorable to the seller than if such sale were a public sale
and, notwithstanding such circumstances, agrees that any such private sale shall
be deemed to have been made in a commercially reasonable manner. Pledgee shall
be under no obligation to delay a sale of any of the TELP Partnership Interest
for the period of time necessary to permit the Borrower to register such
securities for public sale under the Securities Act, or under applicable state
securities laws, even if the Borrower would agree to do so.

                  (d) The Pledgor further agrees to do or cause to be done all
such other acts and things as may be necessary to make such sale or sales of any
portion of all of the TELP Partnership Interest valid and binding and in
compliance with any and all applicable laws, regulations, orders, writs,
injunctions, decrees or awards of any and all courts, arbitrators or
governmental instrumentalities, domestic or foreign, having jurisdiction over
any such sale or sales, all at the Pledgor's expense. The Pledgor further agrees
that a breach of any of the covenants contained in this SECTION 9 will cause
irreparable injury to Pledgee, that Pledgee has no adequate remedy at law in
respect of such breach and, as a consequence, agrees that each and every
covenant contained in this paragraph shall be specifically enforceable against
the Pledgor and the Pledgor hereby waives and agrees not to assert any defenses
against an action for specific performance of such covenants except for a
defense that no default of the covenants, terms or conditions of the Loan
Agreement has occurred. The Pledgor further acknowledges the impossibility of
ascertaining the amount of damages which would be suffered by Pledgee by reason
of a breach of any such covenants and, consequently, agrees that, if Pledgee
shall sue for


PLEDGE AND SECURITY AGREEMENT - Page 6
(TIDEL CASH SYSTEMS, INC.)

<PAGE>   7


damages for breach, Pledgor shall pay, as liquidated damages and not as a
penalty, an amount equal to the value of the TELP Partnership Interest on the
date Pledgee shall demand compliance with this paragraph, but in no event to
exceed the amount of the Obligations.

         10. Waiver of Subrogation. Notwithstanding anything to the contrary in
this Agreement, unless and until the Obligations have been indefeasibly paid and
performed in full, the Pledgor hereby irrevocably waives all rights Pledgor may
have at law or in equity (including, without limitation, any law subrogating the
Pledgor to the rights of the Pledgee) to seek contribution, indemnification, or
any other form of reimbursement from the Borrower, any other guarantor or
pledgor, or any other person now or hereafter primarily or secondarily liable
for any obligations of the Borrower to the Pledgee, for any disbursement made by
the Pledgor under or in connection with this Agreement or otherwise. The Pledgor
further agrees that, to the extent that the waiver of any such subrogation,
contribution, reimbursement, indemnity or otherwise is found to be void or
voidable for any reason, any such rights which the Pledgor may have shall be
junior and subordinate in all respects to the rights of the Pledgee against the
Borrower.

         11. Actions by Pledgee. No action that the Pledgee may take or omit to
take in connection with the Loan Agreement or any of the Loan Documents, any
indebtedness owing by Borrower to the Pledgee (including, without limitation,
renewals, extensions, modifications and increases thereof), or any security for
the payment of any indebtedness of Borrower to the Pledgee, or for the
performance of any obligation or undertaking of Borrower, nor any course of
dealing with Borrower or any other Person, shall release the Pledgor from his
obligations hereunder, affect this Agreement in any way, or afford the Pledgor
any recourse against the Pledgee. By way of example, but not in limitation of
the foregoing, the Pledgor hereby expressly agrees that the Pledgee may, from
time to time, without notice to the Pledgor:

                  (a) sell, assign, transfer or grant participations in the
Loans and/or any right held by the Pledgee pursuant to or in connection with the
Loan Agreement and the Loan Documents;

                  (b) amend, change, or modify, in whole or in part, any
documents or instruments evidencing, securing or relating to any indebtedness or
undertaking of Borrower or TTI to the Pledgee;

                  (c) accelerate, change, extend, or renew the time for payment
of the Notes or any other indebtedness arising under any documents or
instruments evidencing, securing or relating to any indebtedness or undertaking
of Borrower or TTI to the Pledgee;

                  (d) compromise or settle any amount due or owing, or claimed
to be due or owing, under the Notes or under any documents or instruments
evidencing, securing or relating to any indebtedness or undertaking of Borrower
or TTI to the Pledgee;

                  (e) surrender, release, or subordinate any or all security for
any indebtedness or undertaking of Borrower or TTI to the Pledgee or accept
additional or substituted security therefor;


PLEDGE AND SECURITY AGREEMENT - Page 7
(TIDEL CASH SYSTEMS, INC.)

<PAGE>   8


                  (f) release any guarantor or pledgor of any indebtedness or
undertaking of the Borrower or TTI to the Pledgee, or substitute or add
additional guarantors or pledgors; and

                  (g) apply collateral securing the Notes to other indebtedness
also secured by such collateral.

The provisions of this Agreement shall extend and be applicable to all renewals,
increases, amendments, extensions, modifications of and substitutions for the
Loan Agreement and the Loan Documents, and all references herein to the Loan
Agreement and the Loan Documents shall be deemed to include any renewal,
increase, extension, amendment or modification thereof or substitution therefor.

         12. No Impairment. The obligations, guaranties, undertakings,
covenants, agreements and duties of the Pledgor under this Agreement shall not
be affected or impaired by any of the following, although without notice to or
consent of the Pledgor:

                  (a) any failure, omission or delay on the part of the Pledgee
(i) to enforce, assert or exercise any right, power or remedy conferred on the
Pledgee by the provisions of the Loan Agreement and the Loan Documents or
otherwise inuring to the holders of the rights of the Pledgee under the Loan
Agreement and the Loan Documents, or (ii) to make demand first upon Borrower or
TTI or to proceed against Borrower or TTI;

                  (b) the voluntary or involuntary liquidation, dissolution,
sale of all or substantially all assets, marshalling of assets or liabilities,
receivership, conservatorship, assignment for the benefit of creditors,
insolvency, bankruptcy, reorganization, arrangement, composition or other
proceedings under laws for the protection of debtors affecting Borrower or TTI
or any of the assets of Borrower or TTI, or any discharge from liability or
rejection of burdensome contracts or obligations in the course of or resulting
from any such proceedings;

                  (c) the release, by operation of law or otherwise, of Borrower
or TTI or any guarantor from any obligation under the Loan Agreement or any of
the Loan Documents;

                  (d) the invalidity, deficiency, illegality or unenforceability
of the Loan Agreement and the Loan Documents, in whole or in part, or of any of
the provisions thereof, or failure to perfect or maintain perfection of any
security, or any defense or excuse for failure to perform on account of force
majeure, act of God, casualty, impossibility, impracticability, or other defense
or excuse whatsoever; or

                  (e) without limiting the foregoing, any fact or event (whether
or not similar to any of the foregoing) which in the absence of this provision
would or might constitute or afford a legal or equitable discharge or release of
or defense to a guarantor or surety.

None of the foregoing shall be a defense to this Agreement, and this Agreement
is a primary obligation of the Pledgor.

<PAGE>   9


         13. Other Pledgors or Guarantors. The liabilities and obligations of
the Pledgor hereunder shall not be reduced or limited by reason of any guaranty
or pledge executed in favor of the Pledgee by any other Person, and this
Agreement shall be enforceable against the Pledgor without regard to any such
guaranty or pledge.

         14. Representations, Warranties and Covenants of the Pledgor. The
Pledgor represents and warrants that:

                  (a) it is the legal, record and beneficial owner of, and has
good and, subject to applicable securities laws described in SECTION 9 hereof,
marketable title to, the TELP Partnership Interest, subject to no pledge, lien,
mortgage, hypothecation, security interest, charge, option, or other encumbrance
whatsoever, except the existing lien and security interest created by this
Agreement;

                  (b) it is duly organized, validly existing and in good
standing under the laws of its jurisdiction of incorporation and has full power,
authority and legal right to pledge the TELP Partnership Interest pursuant to
this Agreement;

                  (c) this Agreement has been duly authorized, executed and
delivered by Pledgor and constitutes a legal, valid and binding obligation of
the Pledgor, and is enforceable in accordance with its terms;

                  (d) other than the approvals, if any, required under the TELP
Partnership Agreement, no consent of any other party (including, without
limitation, the stockholders or creditors of the Pledgor) and no consent,
license, permit, approval or authorization of, exemption by, notice or report
to, or registration, filing or declaration with, any Governmental Authority,
domestic or foreign, is required to be obtained by the Pledgor or the Pledgee in
connection with the execution, delivery or performance of this Agreement or the
pledge of the TELP Partnership Interest hereunder, in each case which has not
been obtained or made, as the case may be, and is not in full force and effect;

                  (e) the execution, delivery and performance of this Agreement
will not violate any provision of any applicable law, or of any mortgage,
indenture, lease, contract, or other agreement, instrument or undertaking to
which Pledgor is a party or which purports to be binding upon Pledgor or upon
any of its assets and will not result in the creation or imposition of any lien,
charge or encumbrance on or security interest in any of the assets of Pledgor
except as contemplated by this Agreement or the Loan Agreement;

                  (f) the TELP Partnership Interest is not a security, as
defined in Article 8 of the Texas Business and Commerce Code; and

                  (g) the pledge and assignment of the Collateral pursuant to
this Agreement constitutes and will constitute a valid first lien on and a first
perfected security interest in the Collateral, and the proceeds thereof, subject
to no prior Lien, or to any agreement purporting to

PLEDGE AND SECURITY AGREEMENT - Page 9
(TIDEL CASH SYSTEMS, INC.)


<PAGE>   10


grant to any third party other than Pledgee a security interest in the property
or assets of the Pledgor which would include the Collateral.

                  Pledgor covenants and agrees (a) that at its expense it will
defend the right, title and security interest of the Pledgee in and to the
Collateral against the claims and demands of all persons whomsoever;

                  (b) that it will have like title to and right to pledge any
other property at any time hereafter pledged to the Pledgee as Collateral
hereunder and will likewise defend the right of the Pledgee thereto and security
interest therein;

                  (c) to observe, perform and discharge all obligations,
covenants and warranties provided for under the terms of the TELP Partnership
Agreement to be kept, observed and performed by Pledgor, and to inform Pledgee
promptly in writing of any notice received by Pledgor: (i) with respect to any
obligation to be performed but alleged not to have been performed by Pledgor
under the TELP Partnership Agreement; and (ii) of any default or claimed default
by any party to the TELP Partnership Agreement;

                  (d) to enforce or secure the enforcement, in the name of
Pledgee, of the performance of each and every obligation, term, covenant,
condition and agreement to be performed by any other party under the terms of
the TELP Partnership Agreement;

                  (e) not to vote in favor of, or cause, the termination of the
Borrower, or vote in favor of any modification, extension, renewal, amendment or
material alteration of any term of the TELP Partnership Agreement without, in
each such instance, the prior written consent of Pledgee; and

                  (f) that Pledgee, after the occurrence of an Event of Default,
without notice to Pledgor, shall have the right at any time and from time to
time to notify and direct the general partner, or such other appropriate party,
of the Borrower to thereafter make all disbursements of the Proceeds directly to
Pledgee; such general partner or other party shall be fully protected in relying
on the written statement of Pledgee that it holds a security interest that
entitles Pledgee to receive any such disbursement, and the receipt by Pledgee of
such disbursements shall be full acquittance thereof to the party making such
disbursements.

         15. No Disposition. Without the prior written consent of the Pledgee,
Pledgor agrees that it will not sell, assign, transfer, exchange, or otherwise
dispose of, or grant any option with respect to, the Collateral, nor will it
create, incur or permit to exist any pledge, lien, mortgage, hypothecation,
security interest, charge, option or any other encumbrance with respect to any
of the Collateral, or any interest therein, or any proceeds thereof, except for
the lien and security interest provided for by this Agreement and except as
permitted by this Agreement or by the Loan Agreement.

         16. Further Assurances. Pledgor agrees that at any time and from time
to time upon the written request of the Pledgee, the Pledgor will execute and
deliver such further documents


PLEDGE AND SECURITY AGREEMENT - Page 10
(TIDEL CASH SYSTEMS, INC.)

<PAGE>   11


and do such further acts and things which are necessary in the reasonable
judgment of the Pledgee to effect the purpose of this Agreement or to obtain,
maintain and perfect the security interest granted under this Agreement in any
applicable jurisdiction, and any expense of Pledgee so incurred shall be a part
of the Obligations.

         17. Severability. Any provision of this Agreement which is prohibited
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

         18. No Waiver; Cumulative Remedies. The Pledgee shall not by any act,
delay, omission or otherwise be deemed to have waived any of its rights or
remedies hereunder and no waiver shall be valid unless in writing, signed by the
Pledgee, and then only to the extent therein set forth. A waiver by the Pledgee
of any right or remedy hereunder on any one occasion shall not be construed as a
bar to any right or remedy which Pledgee would otherwise have on any future
occasion. No failure to exercise nor any delay in exercising on the part of the
Pledgee, any right, power or privilege hereunder, shall operate as a waiver
thereof; nor shall any single or partial exercise of any right, power or
privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. The rights and remedies herein
provided are cumulative and may be exercised singly or concurrently, and are not
exclusive of any rights or remedies provided by law.

         19. Waivers, Amendments, Entirety. None of the terms or provisions of
this Agreement may be waived, altered, modified or amended except by an
instrument in writing, duly executed by the Pledgee. This Agreement and all
obligations of the Pledgor hereunder shall be binding upon the successors and
assigns of the Pledgor, and shall, together with the rights and remedies of
Pledgee hereunder, inure to the benefit of Pledgee and its successors and
assigns. THIS AGREEMENT REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES
HERETO 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.

         20. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND BE
CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS
WITHOUT GIVING EFFECT TO THE CHOICE OF LAWS RULES THEREOF.

         21. Counterparts. This Agreement may be executed in any number of
counterparts and by the different parties on separate counterparts and each such
counterpart shall be deemed to be an original, but all such counterparts shall
together constitute one and the same Agreement.

         22. Reinstatement. This Agreement shall remain in full force and effect
and continue to be effective should any petition be filed by or against the
Pledgor, Borrower or TTI for liquidation or reorganization, should the Pledgor,
Borrower or TTI become insolvent or make an

assignment for the benefit of creditors or should a receiver or trustee be
appointed for all or any significant part of the Pledgor's assets or the assets
of Borrower or TTI and shall continue to be effective or be reinstated, as the
case may be, if at any time payment and performance of the Obligations, or any
part thereof is, pursuant to applicable law, rescinded or reduced in amount, or
must otherwise be restored or returned by any obligee of the Obligations,
whether as a "voidable preference", "fraudulent conveyance", or otherwise, all
as though such payment or performance had not been made. In the event that any
payment, or any part thereof, is rescinded, reduced, restored or returned, the
Obligations shall be reinstated and deemed reduced only by such amount and not
so rescinded, reduced, restored or returned.

         IN WITNESS WHEREOF, Pledgor has caused this Agreement to be duly
executed and delivered as of the day and year first above written.

                              REVOLVING CREDIT NOTE


                                  Dallas, Texas

$7,000,000.00                                                 September 30, 1999

         FOR VALUE RECEIVED, TIDEL ENGINEERING, L.P., a Delaware limited
partnership (herein called "Borrower"), promises to pay to the order of CHASE
BANK OF TEXAS, N.A., a national banking association (herein called "Payee"), at
2200 Ross Avenue, Dallas, Texas 75201, or at such other place as Payee may
hereafter designate in writing, in immediately available funds and in lawful
money of the United States of America, the principal sum of SEVEN MILLION AND
NO/100 DOLLARS ($7,000,000.00) (or the unpaid balance of all principal advanced
against this note, if that amount is less), together with interest on the unpaid
principal balance of this note from time to time outstanding until maturity on
September 30, 2001, at the rate or rates provided for in the Credit Agreement
and interest on all past due amounts at the Past Due Rate as provided in the
Credit Agreement; provided, that for the full term of this note, the interest
rate produced by the aggregate of all sums paid or agreed to be paid to the
holder of this note for the use, forbearance or detention of the debt evidenced
hereby shall not exceed the Highest Lawful Rate, if any, applicable to Payee.

         If, for any reason whatever, the interest paid or received on this note
during its full term produces a rate which exceeds the Highest Lawful Rate, if
any, applicable to Payee, the holder of this note shall refund to the payor or,
at the holder's option, credit against the principal of this note such portion
of said interest as shall be necessary to cause the interest paid on this note
to produce a rate equal to the Highest Lawful Rate, if any, applicable to payee.
All sums paid or agreed to be paid to the holder of this note for the use,
forbearance or detention of the indebtedness evidenced hereby shall, to the
extent permitted by applicable law, be amortized, prorated, allocated and spread
in equal parts throughout the full term of this note, so that the interest rate
is uniform throughout the full term of this note. 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 Chapter 303 of the Texas Finance Code, as amended, or if permitted by
applicable law and effective upon the giving of the notices required by Section
303.403 of 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 303 of the
Texas Finance Code, whichever that Lender shall elect to substitute for the
"weekly ceiling," and vice versa, each such substitution to have the effect
provided in Chapter 303 of the Texas Finance Code; and 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 303 of the Texas Finance Code. Pursuant
Section 346.004 of the Texas Finance Code, as amended, Borrower agrees that
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.
