    The accompanying consolidated balance sheets and related interim
    consolidated statements of operations and cash flows of Tidel Technologies,
    Inc., a Delaware corporation formerly known as American Medical

    management, these financial statements include all adjustments (consisting
    only of normal recurring items) necessary for their fair presentation in
    accordance with generally accepted accounting principles. Preparing
    financial statements requires management to make estimates and assumptions
    that affect the reported amounts of assets, liabilities, revenues and
    expenses. Actual results may differ from these estimates. Interim results
    are not necessarily indicative of results for a full year. The information
    included in this Form 10-Q should be read in conjunction with the Company's
    Annual Report on Form 10-K for the year ended September 30, 1996.

(3) NET INCOME PER SHARE

    Net income per share is computed by dividing the net income by the weighted
    average number of common and common equivalent shares outstanding during the
    period. For purposes of this calculation, outstanding warrants and employee
    stock options are considered common stock equivalents


(4) INVESTMENT IN 3CI

    The Company owns 680,818 shares of the common stock of 3CI Complete
    Compliance Corporation. The investment is carried at market value.

(5) LITIGATION

    The Company is subject to certain litigation and claims arising in the
    ordinary course of business. In the opinion of management, 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 2.     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
            FINANCIAL CONDITION AND RESULTS OF OPERATIONS

                             RESULTS OF OPERATIONS

    The Company develops, manufactures, sells and supports products designed for
    specialty retail marketers, including automated teller machines and related
    software (the "AnyCard" or "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).

    PRODUCT REVENUES

    Total revenues increased $2,375,436, or 42%, for the third quarter of fiscal
    1997 over the comparable quarter of 1996. On a year-to-date basis, revenues
    increased $6,477,393, or 44%, compared to the same period of the prior
    fiscal year. As discussed below, a significant increase in AnyCard sales was
    the principal factor in the Company's revenue growth. Revenue by product is
    detailed in the following table:

                                   Three Months Ended  Nine Months Ended
                                       June 30,            June 30,

                                   ======   =======   =======   =======

    AnyCard product sales for the quarter ended June 30, 1997 increased 58% over
    the comparable period in 1996. On a year-to-date basis, AnyCard sales
    increased 81% when compared to the same period in 1996. These increases are
    attributable to strong demand for the single cassette model ATM, which has
    been the Company's largest selling product since its introduction in
    November 1995.

    TACC product sales increased 23% for the quarter ended June 30, 1997, when
    compared to the same period in 1996. As expected, however, these sales were
    virtually unchanged on a year-to-date basis.

    All marketing activities for EMS products have terminated as the marketing
    focus of the Company is shifted to its two other product lines, and as a
    result, these sales have continued to decline. Certain existing customers
    have continued to purchase these products, however, to complete retrofit
    projects that are currently in progress.

                                       5
<PAGE>
    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 was 38% of revenues for the quarters ended June 30, 1997 and
    1996. On a year-to-date basis, gross profit decreased slightly from 37% of
    revenues in 1996 to 36% of revenues in 1997. The decrease was primarily due
    to discounts on sales prices of older tube-type ATMs shipped thus far in
    fiscal 1997, and costs related to upgraded features in the single cassette
    model. However, management expects gross profit to improve for the balance
    of fiscal 1997, due to volume discounts from raw material suppliers and
    higher margins on new products developed.

    As a percentage of revenues, selling, general and administrative expense was
    25% and 27% in the respective third quarters of fiscal 1997 and 1996. On a
    year-to-date basis, selling, general and administrative expense was 24% of
    revenues in 1997, compared to 27% of revenues in 1996. Management believes
    that selling, general and administrative expense, as a percentage of
    revenues, should continue to decrease over the remainder of the year.

    Depreciation and amortization increased during fiscal 1997 due to the
    additions of property, plant and equipment utilized in the development of
    new automated teller machine products.

    Interest expense increased during fiscal 1997 as a result of increased
    indebtedness in the early part of the year, offset somewhat by a decline in
    average rates for borrowed funds.

                   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
    June 30, 1997 and September 30, 1996:

                                  June 30,   September 30,
                                    1997         1996       Increase
                                 ----------   ----------   ----------
          Shareholders' equity   $7,795,380   $4,128,771   $3,666,609
          Tangible net worth .    6,964,037    3,191,480    3,772,557
          Working capital ....    9,030,015    2,220,823    6,809,192

    The improvement in working capital is principally due to increased accounts
    receivable and the replacement of a short-term note payable with a long-term
    credit facility. The increase in accounts receivable arose from increased
    sales, and the provision of extended payment terms to principal customers
    for certain large orders. The replacement of the short-term note payable
    with the long-term credit facility resulted from the financing described in
    the following paragraph.

    During June, 1997, the Company's wholly owned subsidiary entered into a
    revolving credit agreement with Texas Commerce Bank National Association.
    The revolving credit agreement, which replaced the subsidiary's existing
    short-term revolving facility, provides for borrowings up to $5,000,000 at
    the prime rate, with certain LIBOR alternatives, until May 31, 1999. At June
    30, 1997, $3,654,604 was outstanding pursuant to the revolving credit
    agreement.

                                       6
<PAGE>
    The Company continues to own 680,818 shares of 3CI common stock subsequent
    to its divestiture of a majority interest in February 1994. The Company has
    no immediate plans for the disposal of the shares, and accordingly, the
    shares may be utilized to collateralize borrowings. At present, 480,818
    shares are pledged to secure an outstanding note payable in the principal
    amount of $400,000.

    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 on January 29, 1997.
    As of June 30, 1997, warrants to purchase 2,125,975 shares have been
    exercised generating net proceeds to the Company of approximately
    $2,390,000, and warrants representing 761,244 shares have expired. As of
    June 30, 1997, the Company had outstanding warrants to purchase 2,630,281
    shares of common stock, which if exercised would generate proceeds to the
    Company of approximately $2,200,000.

    Of the total warrants exercised, certain directors purchased 700,000 shares
    through a contribution of cash and promissory notes. The notes, which are
    due March 31, 1998, have an aggregate principal balance of $743,000, bear
    interest at 10% per annum, and are secured by a pledge of all of the shares.

    The Company's research and development budget for fiscal 1997 has been
    estimated at $1,300,000. 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 $863,000 and
    $656,000 for the nine months ended June 30, 1997 and 1996, respectively.

    With its present capital resources, its potential capital from the exercise
    of warrants, and with its borrowing facility, the Company 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.

    SEASONALITY

    The Company can experience seasonal variances in operations and historically
    has its lowest dollar volume sales months between November and March. With
    the favorable sales of its automated teller machines, however, the Company
    did not experience any downturn during this period. The Company's operating
    results for any particular quarter may not be indicative of the results for
    the future quarter or for the year.

    MAJOR CUSTOMERS AND CREDIT RISKS

    The Company generally does not require collateral or other security from its
    customers and would incur an accounting loss equal to the carrying value of
    the accounts receivable if a customer failed to perform according to the
    terms of the credit arrangements. Sales to major customers were as follows
    for the three and nine months ended June 30, 1997 and 1996:

    Foreign sales accounted for 6% and 2% of the Company's total sales during
the three months ended June 30, 1997 and 1996, respectively, and 6% and 9% of
the Company's total sales during the nine months ended June 30, 1997 and 1996,
respectively.

                                CREDIT AGREEMENT

      THIS CREDIT AGREEMENT (together with all amendments, modifications and
supplements hereto and restatements hereof, this "AGREEMENT") is made and
entered into as of June 12th, 1997, by and among TIDEL ENGINEERING, INC.
("BORROWER"), a Delaware corporation, and TEXAS COMMERCE BANK NATIONAL
ASSOCIATION, a national banking association ("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 (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 (b) the Applicable Margin. For
purposes of this 
<PAGE>
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 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

      2.4   TERMINATION AND REDUCTIONS OF COMMITMENTS.

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

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

            (c) To effect the payment of any and all Commitment Fees and all
other Obligations outstanding and owing hereunder or under any other Loan
Documents, subject to the provisions of SECTIONS 2.1 AND 4.1 hereof, the Lender
may, but shall not be obligated to, make a Loan if (i) such Loan is to be made
prior to the Maturity Date, (ii) the Availability would be equal to or greater
than zero after giving effect to such Loan, and (iii) no Default or Event of
Default shall have occurred which is then continuing. The inability of the
Lender to cause the payment of any such Commitment Fees or other Obligations in
accordance with the preceding sentence shall 

                                       22
<PAGE>
not in any way whatsoever affect the Borrower's and Guarantors' obligation to
otherwise pay such amounts in accordance with the applicable terms hereof or of
any other Loan Documents.

      2.5   MANDATORY AND VOLUNTARY PREPAYMENTS.

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

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

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

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

                  (2) Prepayments applied to any LIBOR Rate Borrowing may be
      made on any Business Day, PROVIDED, that (i) the Borrower shall have given
      the Lender at least five (5) Business Days' prior irrevocable written or
      telecopied notice of such prepayment, specifying the principal amount of
      the LIBOR Borrowing to be prepaid, the particular LIBOR Borrowing to which
      such prepayment is to be applied and the prepayment date; 

                                       23
<PAGE>
      and (ii) if such prepayment is made on any day other than the last day of
      the Interest Period corresponding to the LIBOR Borrowing to be prepaid,
      the Borrower shall pay directly to the Lender, on the last day of such
      Interest Period, the Consequential Loss as a result of such prepayment.

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

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

      2.6   NOTE; PAYMENTS.

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

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

            (c) Subject to SECTION 9.6 hereof, the Borrower hereby agrees to pay
accrued interest on the unpaid principal balance of the Loans on the Interest
Payment Dates, commencing the first of such dates to occur after the date
hereof. After the Maturity Date, accrued and unpaid interest on the Loans shall
be payable on demand.

            (d) To effect payment of accrued interest owing on the Loans as of
the Interest Payment Dates, subject to the provisions of SECTIONS 2.1 AND 4.1
hereof, the Lender may, but shall not be obligated to, make a Loan to pay in
full the amount of accrued interest owing and payable on the Loans as of the
respective Interest Payment Date if (i) such Loan is to be made prior to the
Maturity Date, (ii) the Availability would be equal to or greater than zero
after giving effect to such 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 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 Note shall be applied to payment of the aggregate unpaid
principal amounts 

                                       24
<PAGE>
of the Note, with the balance of any such prepayments, if any, being applied to
accrued interest. Payments of accrued interest on the Note in accordance with
SECTION 2.6(C) hereof shall be applied to the aggregate accrued interest then
outstanding under the Note, while payment by the Borrower of the aggregate
principal amount outstanding under the Note on the Maturity Date shall be
applied to principal.

            (b) All sums payable by the Borrower to the Lender hereunder or
pursuant to the 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 LOANS.

            (a) Subject to SECTION 9.6 hereof, the 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 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 Loans to which they are applicable shall be binding and conclusive,
absent manifest error. Interest on the 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 Note. Each change
in Interest Options shall be a conversion of the rate of interest applicable to
the specified portion of the Loans, but such conversion alone shall not change
the outstanding principal balance of the 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 E 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 

                                       25
<PAGE>
      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 Loan is to be a LIBOR Borrowing, (y) an
      existing LIBOR Borrowing is maturing at the time that a new Loan is being
      requested and the Borrower is electing to have such existing portion of
      the outstanding principal balance of the Note going forward bear interest
      at the same Interest Option and for the same Interest Period as the new
      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 Loan, then the Rate Selection Notice shall be
      included in the Request for Extension of Credit applicable to the new
      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.

                  (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 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 

                                       26
<PAGE>
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
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 Note being maintained on the basis of the Adjusted
LIBOR Rate:

                  (1) subject Lender (or make it apparent that 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
      
                  (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 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 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 Lender for such increased cost or reduced amount. The
Lender 

                                       27
<PAGE>
will promptly notify the Borrower in writing of any event, upon becoming
actually aware of it, which will entitle 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 appropriate 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
Lender of making and 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 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
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
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 

                                       28
<PAGE>
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 Lender has a LIBOR Lending Office which differs from its
Domestic Lending Office, all Loans advanced by Lender's LIBOR Lending Office
shall be deemed to have been made by Lender and the obligation of the Borrower
to repay such Loans shall nevertheless be to Lender and shall be deemed held by
Lender, to the extent of such portions of the Loan, for the account of Lender's
LIBOR Lending Office.

            (g) Notwithstanding any provision of this Agreement to the contrary,
Lender shall be entitled to fund and maintain its funding of all or any part of
the 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 Lender had actually funded and maintained its portion of each LIBOR
Borrowing during each Interest Period for the 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 Commitment from time
to time prior to the 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 

                                       29
<PAGE>
Lender's Current Sum at such time, would exceed the lesser of (1) the 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 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 4.1 hereof) by
making a Loan if (i) such Letter of Credit Advance is (and such Loan is to be)
made prior to the Maturity Date, (ii) the Availability would be equal to or
greater than zero after giving effect to such Loan and (iii) no Default or Event
of Default shall have occurred which is then continuing. If Lender does not make
a Loan to satisfy such Letter of Credit Advance, each such letter of Credit
Advance shall be considered for all purposes as a demand 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
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 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 9.6 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 

                                       30
<PAGE>
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

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

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:

                  (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.

                                       31
<PAGE>
      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 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 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 9.6 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 Lender, the Borrower shall pay to

                                       32
<PAGE>
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 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 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 Lender) exceeds (b) the
aggregate amount of interest actually paid to the Lender on the Note on or prior
to such day.

      2.12 USE OF PROCEEDS. The proceeds of the Loans will be used to (i)
refinance the existing Indebtedness of Borrower to Frost Capital, and (ii)
finance general working capital needs of Borrower.

3. COLLATERAL.

      3.1 SECURITY DOCUMENTS. The Loans and all other Obligations shall be
secured by Collateral described in the Security Documents and are entitled to
the benefits thereof. The Borrower shall duly execute and deliver the Security
Documents, all consents of third parties necessary to permit the effective
granting of the Liens created thereby, financing statements pursuant to the
Uniform Commercial Code and other documents, all in Proper Form, as may be
reasonably required by the Lender to grant to the Lender a
valid, perfected and enforceable first priority Lien on and security interest in
the Collateral (subject only to the Liens permitted under SECTION 7.2 hereof).

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

money of the Borrower (other than the Indebtedness hereunder), and (iv) all
obligations of the Borrower to issuers of appeal bonds issued for account of the
Borrower. The Borrower shall, upon request by the Lender, deliver to the Lender
a complete and correct copy of all such credit agreements, indentures,
capitalized leases, letters of credit, guarantees and other instruments or
leases described in SCHEDULE 5.16 or arising after the date hereof, including
any modifications or supplements thereto, as in effect on the date hereof.

      5.17 ENVIRONMENTAL MATTERS. Except as is described on SCHEDULE 5.17
attached hereto, no activity of the Borrower requires any Environmental Permit
which has not been obtained and which is not now in full force and effect. The
Borrower is in compliance with all limitations, restrictions, conditions,
standards, prohibitions, requirements, obligations, schedules and timetables
contained in any applicable Requirement of Environmental Law or Environmental
Permit. The Borrower (and, to the knowledge of the Borrower, each of the prior
owners or operators and predecessors in interest with respect to any of its
Property) (i) has obtained and maintained in effect all Environmental Permits,
(ii) along with its Property has been (except as disclosed in the lease of the
premises known as 2310 McDaniel Drive, as in effect on the Closing Date, and as
to which, to the knowledge of Borrower, proper remediation has occurred pursuant
to the terms of such lease) and is in compliance with all applicable
Requirements of Environmental 

                                       40
<PAGE>
Law and Environmental Permits, (iii) along with its Property is not subject to
any (A) Environmental Claims or (B) Environmental Liabilities, in either case
direct or contingent, and whether known or unknown, arising from or based upon
any act, omission, event, condition or circumstance occurring or existing on or
prior to the date hereof, and (iv) has not received individually or collectively
any notice of any violation or alleged violation of any Requirements of
Environmental Law or Environmental Permit or any Environmental Claim in
connection with its Property. The present and future liability (including any
Environmental Liability and any other damage to Persons or Property), if any, of
the Borrower and with respect to the Property of the Borrower which is
reasonably expected to arise in connection with Requirements of Environmental
Law, Environmental Permits and other environmental matters will not have a
Material Adverse Effect.

      5.18 NO CHANGE IN CREDIT CRITERIA OR COLLECTION POLICIES. There has been
no material adverse change in credit criteria or collection policies concerning
Receivables of the Borrower since June 1, 1991.


      5.19 SOLVENCY.

            (a) The fair salable value of the assets of the Borrower is 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 small
capital for the Borrower to carry out its business as now conducted and as
proposed to be conducted including the capital needs of the Borrower, taking
into account the particular capital requirements of the business conducted by
the Borrower and projected capital requirements and capital availability
thereof.

            (c) The Borrower does not intend to incur debts beyond its 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
subparagraph (c) of this SECTION 5.19), should at all times be sufficient to pay
all such judgments promptly in accordance with their terms.

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 redate
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.

irrevocably authorized, in accordance with the terms of the implementation and
processing instructions for the applicable Lockbox Agreement(s), to cause all
such remittances on all Receivables to be promptly deposited in such account or
accounts designated by the Lender. All remittances and payments that are

above are in effect and are continuing, the Borrower shall cause all payments,
if any, received by the Borrower or any of its Subsidiaries on account of
Receivables which are not forwarded directly to the above-described 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 6.15(B) above.

            (d) In addition to the financial reporting requirements set forth in
SECTION 6.3 hereof, as long as the daily collection procedure implemented by the
provisions of SECTION 6.15(B) above is in effect, the Borrower shall furnish to
the Lender on each Business Day a copy of a Receivables report setting forth the
sales, collections and credits 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
6.15(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.

      6.16 ADDITIONAL RECEIVABLES DOCUMENTATION. In addition to the Receivables
information delivered pursuant to the other provisions of this Agreement,
furnish such further schedules and/or information as the Lender may reasonably
require relating to the Receivables (including without limitation, sales
invoices if the same are required by the Lender), and the Borrower shall notify
the Lender of any non-compliance in respect of the representations and
warranties contained in SECTION 5.21 hereof. The items to be provided under this
SECTION 6.16 are to be in Proper Form and are to be executed and delivered to
the Lender from time to time solely for its convenience in maintaining records
of the Collateral. The Borrower's failure to give any of such items to the
Lender shall not affect, terminate, modify or otherwise limit the Lender's Lien
or security interest in the Collateral.

9.    MISCELLANEOUS.

      9.1 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 9.11 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.

      9.2 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
4.1(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 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 9.2, 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 4.1(A) hereof shall be effective only when actually
received by the Lender.

      9.3 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 

                                       58
<PAGE>
CONFLICTS OF LAWS PRINCIPLES THEREOF) AND THE UNITED STATES OF AMERICA.

      9.4 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 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 Note and the payment of all amounts due under the Loan
Documents.

      9.5 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.

      9.6 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 9.6 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 nonprincipal 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 nonusurious 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
Lender, the rate at which interest shall accrue for the applicable type of
borrowing owing to Lender shall automatically be fixed by operation of this
sentence at the Highest Lawful Rate applicable to Lender for that day, and shall
remain fixed at the Highest Lawful Rate applicable to Lender for each day
thereafter until the total amount of interest accrued and owing to Lender equals
the total amount of interest which would have accrued on such borrowing owing to
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, 

                                       59
<PAGE>
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 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 Lender shall be determined by dividing
the applicable Highest Lawful Rate, if any, for 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 9.6, or be construed to create a contract to
pay Lender for the use, forbearance or detention of money at an interest rate in
excess of the Highest Lawful Rate applicable to Lender. If the term of any Loans
or the Note 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 "indicated rate ceiling" from time to
time in effect under Article 1.04, 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 1.04 (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 Article
1.04, whichever that Lender shall elect to substitute for the "indicated rate
ceiling," and vice versa, each such substitution to have the effect provided in
such Article 1.04; 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 subsection
(h)(1) of such Article 1.04. Pursuant to Article 15.10(b) of Chapter 15,
Subtitle 79, Revised Civil Statutes of Texas, 1925, as amended, Borrower agrees
that such Chapter 15 (which regulates certain revolving credit loan accounts and
revolving tri-party accounts) shall not govern or in any manner apply to the
Obligations.

      9.7 SURVIVAL. The obligations of the Borrower under SECTIONS 2.3, 2.4(B),
2.9, 2.10(F), 9.9, 9.10 and 9.17 hereof shall survive the repayment of the
Loans, the termination of the Commitments and the cancellation or expiration of
the Letters of Credit.

      9.8 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.

                                       60
<PAGE>
      9.9 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

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.

      9.10 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

SOLELY TO THE POST-FORECLOSURE ACTIONS OF THE LENDER.

      9.11 AMENDMENTS, WAIVERS, ETC. No amendment, modification or waiver of any
provision of this Agreement, the Note 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.

      9.12 SUCCESSORS AND ASSIGNS.

            (a) This Agreement shall be binding upon and inure to the benefit of

or proposed assignment or participation pursuant to this SECTION 9.12, disclose

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

      9.16 INTENTIONALLY LEFT BLANK.

      9.17 TAXES.

            (a) As used in this SECTION 9.17, 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
      Lender under this Agreement, under the Note 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 Lender
      (or a shareholder or other Person with an interest in Lender), including a
      connection arising from Lender's (or shareholder of 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 Lender having executed, delivered, performed its
      obligations or received a payment under, or enforced, this Agreement, the
      Note 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 Lender under this Agreement, under
      the Note 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 the Note 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 

                                       63
<PAGE>
or withheld, (iii) promptly forward to Lender an official receipt (or certified
copies thereof), or other documentation reasonably acceptable to 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 Lender, in
addition to whatever net amount of such payment is paid to Lender, such
additional amount as is necessary to ensure that the total amount actually
received by Lender (free and clear of Indemnifiable Tax) will equal the full
amount of the payment Lender would have received had no such deduction or
withholding been required. If the Borrower pays any additional amount to Lender
pursuant to the preceding sentence and Lender shall receive a refund of an
Indemnifiable Tax with respect to which, in the good faith opinion of Lender,
such payment was made, 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 Lender under this Agreement, under the Note or under any
other Loan Document, the Borrower agrees to timely and fully pay such Tax to
such Governmental Authority and 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) 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 the
Note or under any other Loan Documents if such measures can, in the sole and
absolute opinion of Lender, be taken without Lender suffering any economic,
legal, regulatory or other disadvantage (provided, however, that 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 9.17 (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 the Note,
exceed the Highest Lawful Rate or the maximum amount of interest permitted to be
charged by applicable laws.

      9.18 WAIVER OF CLAIMS. THE BORROWER HEREBY WAIVES AND RELEASES THE LENDER
FROM ANY AND ALL CLAIMS OR CAUSES OF ACTION WHICH THE BORROWER MAY OWN, HOLD OR
CLAIM IN RESPECT OF ANY OF THEM AS OF THE DATE HEREOF.
                                                                                
      9.19 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 

                                       64
<PAGE>
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 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 Lender will have made any demand under this Agreement, the Note
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 Lender to the Borrower or any such Guarantor.
Should the right of Lender to realize funds in any manner 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. 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.

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

      9.21 ADDITIONAL PROVISIONS REGARDING COLLECTION OF RECEIVABLES; CONTROL OF
INVENTORY AND OTHER COLLATERAL.

            (a) So long as the procedures discussed in SECTION 6.15(B) hereof
have been implemented and are continuing, the Borrower hereby constitutes the
Lender or the Lender's designee as the Borrower's attorney-in-fact with power to
endorse the Borrower's name upon any notes, acceptances, checks, drafts, money
orders or other evidence of payment of any Receivables or any other Collateral
that may come into its possession; to sign or endorse the Borrower's name on any
invoice, bill of lading or other title or ownership documents relating to any
Receivables or inventory, drafts against any customers of the Borrower,
assignments and verifications of Receivables and notices to customers of the
Borrower; to send verifications of Receivables; to notify the U.S. Postal
Service authorities to change the address for delivery of mail addressed to the
Borrower to such address as the Lender may designate at any time after the
occurrence of any Event of Default which is continuing and to do all other acts
and things necessary to carry out this Agreement. All acts of said attorney or
designee are hereby ratified and approved by the Borrower, and said attorneys or
designee shall not be liable for any acts of omission or commission, for any
error of judgment or for any mistake of fact or law, provided that the Lender or
its designee shall not be relieved of liability to the extent it is determined
by a final judicial decision that its act, error or mistake constituted gross
negligence or willful misconduct. The power of attorney granted under this
subparagraph is coupled with an interest and is irrevocable until all of the
Obligations are paid in full and this Agreement and the Commitment is
terminated.

                                       65
<PAGE>
            (b) The Lender, without notice to or consent of the Borrower, at any
time after the occurrence and during the continuation of an Event of Default;
(i) may sue upon or otherwise collect, extend the time of payment of, or
compromise or settle for cash, credit or otherwise upon any terms, any of the
Receivables or any instruments or insurance applicable thereto and/or release
any account debtor thereon; (ii) is authorized and empowered to accept or direct
shipments of inventory and accept the return of the goods represented by any of
the Receivables; and (iii) shall have the right to receive, endorse, assign
and/or deliver in its name or the name of the Borrower any and all checks,
drafts and other instruments for the payment of money relating 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.

                                       66

      9.23 VENUE; SERVICE OF PROCESS. BORROWER, FOR ITSELF, ITS SUCCESSORS AND

      FOR VALUE RECEIVED, TIDEL ENGINEERING, INC., a Delaware corporation
(herein called "BORROWER"), promises to pay to the order of TEXAS COMMERCE BANK
NATIONAL ASSOCIATION, 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 FIVE MILLION DOLLARS
AND NO/100 ($5,000,000.00) (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 "indicated rate ceiling" from time to time in
effect under Article 1.04, 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 1.04 (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 Article
1.04, whichever that Lender shall elect to substitute for the "indicated rate
ceiling," and vice versa, each such substitution to have the effect provided in
such Article 1.04; 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 subsection
(h)(1) of such Article 1.04. Pursuant to Article 15.10(b) of Chapter 15,
Subtitle 79, Revised Civil Statutes of Texas, 1925, as amended, Borrower agrees
that such Chapter 15 (which regulates certain revolving credit loan accounts and
revolving tri-party accounts) shall not govern or in any manner apply to the
Obligations.

      This note has been issued pursuant to the terms of a Credit Agreement
(which, as it may have been or may be amended, restated, modified or
supplemented from time to time, is herein 

<PAGE>
called the "CREDIT AGREEMENT") of even date herewith, by and between Borrower
and Payee, to which reference is made for all purposes. This note is a Note
under the terms of the Credit Agreement, and advances against this note by Payee
or other holder hereof, payments and prepayments hereunder and acceleration
hereof shall be governed by the Credit Agreement. Capitalized words and phrases
used herein and not defined herein and which are defined in the Credit Agreement
shall have the same meanings herein as are ascribed to them in the Credit
Agreement.

      The unpaid principal balance of this note at any time shall be the total
of all principal lent or advanced against this note less the sum of all
principal payments and permitted prepayments made on this note by or for the
account of Borrower. All loans and advances and all payments and permitted
prepayments made hereon may be endorsed by the holder of this note on the
schedule which is attached hereto (and hereby made a part hereof for all
purposes) or otherwise recorded in the holder's records; PROVIDED, that any
failure to make notation of (a) any advance shall not cancel, limit or otherwise
affect Borrower's obligations or any holder's rights with respect to that
advance, or (b) any payment or permitted prepayment of principal shall not
cancel, limit or otherwise affect Borrower's entitlement to credit for that
payment as of the date received by the holder.

      Borrower and any and all co-makers, endorsers, guarantors and sureties
severally waive notice (including, but not limited to, notice of intent to
accelerate and notice of acceleration, notice of protest and notice of
dishonor), demand, presentment for payment, protest, diligence in collecting and
the filing of suit for the purpose of fixing liability and consent that the time
of payment hereof may be extended and re-extended from time to time without
notice to any of them. Each such person agrees that his, her or its liability on
or with respect to this note shall not be affected by any release of or change
in any guaranty or security at any time existing or by any failure to perfect or
maintain perfection of any lien against or security interest in any such
security or the partial or complete unenforceability of any guaranty or other
surety obligation, in each case in whole or in part, with or without notice and
before or after maturity.

      THIS NOTE SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE 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.

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 

                                       4
<PAGE>
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

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 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 

                                       6
<PAGE>
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 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

                                       7
<PAGE>
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 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.

                     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 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.

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

                          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 

                                        9
<PAGE>
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 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 

                                       10
<PAGE>
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 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, 

                                       11
<PAGE>
      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 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.

                              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 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) 

                                       13
<PAGE>
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, 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.

                                       14
<PAGE>
      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 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

                                                                    EXHIBIT 4.06

                        UNCONDITIONAL GUARANTY AGREEMENT

      THIS UNCONDITIONAL GUARANTY AGREEMENT (this "GUARANTY") is executed as of
June 12, 1997, by AMERICAN MEDICAL TECHNOLOGIES, INC., a Delaware corporation,
d/b/a AMT INDUSTRIES, INC. ("GUARANTOR"), for the benefit of TEXAS COMMERCE BANK
NATIONAL ASSOCIATION ("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 between Tidel
Engineering, Inc. ("BORROWER") and Bank, 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:

                                       1
<PAGE>
            (a) All indebtedness, liabilities, obligations and duties evidenced
by the 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
Notes are enforceable against Borrower;

            (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, 

                                       2
<PAGE>
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 

                                       3
<PAGE>
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

required to pay the Obligations in full, without assistance or support of any

security interest or lien contemplated or intended to be given, created or
granted as security for the repayment of the Obligations shall not be properly
perfected or created, or shall prove to be unenforceable or subordinate to any
other security interest or lien, it being recognized and agreed by Guarantor
that Guarantor is not entering into this Guaranty in reliance on, or in
contemplation of the benefits of, the validity, enforceability, collectibility
or value of any collateral for the Obligations;

      SECTION 2.10. OFFSET. The Obligations, and the liabilities and obligations
of Guarantor to Bank hereunder, shall not be reduced, discharged or released
because of or by reason of any existing or future right of offset, claim or
defense of Borrower against Bank, or any other party, or against payment of the
Obligations, whether such right of offset, claim or defense arises in connection
with the Obligations (or the transactions creating the Obligations) or
otherwise; 

      SECTION 2.11. MERGER. The reorganization, merger or consolidation of
Borrower into or with any other entity;

                                       5
<PAGE>
      SECTION 2.12. PREFERENCE. Any payment by Borrower to Bank is held to
constitute a preference under bankruptcy laws, or for any reason Bank is
required to refund such payment or pay such amount to Borrower or someone else;
or 
      SECTION 2.13. OTHER ACTIONS TAKEN OR OMITTED. Any other action taken or
omitted to be taken with respect to the Obligations, or security and collateral
therefor, if any, whether or not such action or omission prejudices Guarantor or
increases the likelihood that Guarantor will be required to pay the Obligations
pursuant to the terms hereof; IT IS THE UNAMBIGUOUS AND UNEQUIVOCAL INTENTION OF
GUARANTOR THAT GUARANTOR SHALL BE OBLIGATED TO PAY THE OBLIGATIONS WHEN DUE,
NOTWITHSTANDING ANY OCCURRENCE, CIRCUMSTANCE, EVENT, ACTION, OR OMISSION
WHATSOEVER, (INCLUDING, WITHOUT LIMITATION, THE UNENFORCEABILITY OF THE NOTE
AGAINST THE BORROWER WHETHER CONTEMPLATED OR UNCONTEMPLATED, AND WHETHER OR NOT
OTHERWISE OR PARTICULARLY DESCRIBED HEREIN, EXCEPT FOR THE FULL AND FINAL
PAYMENT AND SATISFACTION OF THE OBLIGATIONS.

                                   ARTICLE III

                         REPRESENTATIONS AND WARRANTIES

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

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

<PAGE>
      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

      SECTION 3.07. ORGANIZATION AND GOOD STANDING. Guarantor (a) is, and will
continue to be, a corporation duly organized, validly existing, and in good

      SECTION 3.08. SURVIVAL. All representations and warranties made by
Guarantor herein shall survive the execution hereof.

                                   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. 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: 

                                       7
<PAGE>
            (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.

                                       8
<PAGE>
      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 

                                       9
<PAGE>
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, 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, 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
OBLIGATION OF THE COMPANY UNDER THIS SECTION 5.10 SHALL SURVIVE THE PAYMENT IN
FULL OF THE COMPANY'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.

                          PLEDGE AND SECURITY AGREEMENT

      THIS PLEDGE AND SECURITY AGREEMENT (this "AGREEMENT") is executed as of

      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 Initial Pledged Stock, 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:

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

has occurred and is continuing, Pledgee at any time may have the Pledged Stock
registered in its 

                                       2
<PAGE>
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
Issuer or upon the exercise by 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.

      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 

                                       3
<PAGE>
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.

            (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 

                                       4
<PAGE>
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; 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 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 

                                       5
<PAGE>
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 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.

            (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 the
Issuer would agree to do so.

                                       6
<PAGE>

            (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 Issuer 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
Issuer.

      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 Issuer to the Pledgee (including, without limitation,
renewals, extensions, modifications and increases thereof), or any security for
the payment of any indebtedness of Issuer to the Pledgee, or for the performance
of any obligation or undertaking of Issuer, nor any course of dealing with
Issuer 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;

                                       7
<PAGE>
            (b) amend, change, or modify, in whole or in part, any documents or
instruments evidencing, securing or relating to any indebtedness or undertaking
of Issuer 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 Issuer 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 Issuer to the
Pledgee;

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

            (f) release any guarantor or pledgor of any indebtedness or
undertaking of the Issuer 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 Issuer or to proceed
against Issuer;

            (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 Issuer or any of
the assets of Issuer, or any discharge from liability or rejection of burdensome
contracts or obligations in the course of or resulting from any such
proceedings;

                                       8
<PAGE>
            (c) the release, by operation of law or otherwise, of Issuer 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 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, 

                                       9
<PAGE>
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
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 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.
            
      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 

                                       10
<PAGE>
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.

      21. 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.

      22. 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. THE CERTIFICATES REPRESENTING
THE PLEDGED STOCK SHALL BE DELIVERED TO PLEDGOR IN THE STATE OF TEXAS.
                                                                                
      23. 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.
            
      24. 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 or Issuer for liquidation or reorganization, should the Pledgor or
Issuer 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 Issuer 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.

      WHEREAS, Pledgor has delivered to Pledgee a validly executed promissory
note (the "Note") of even date herewith in the principal amount of
$________________, maturing and bearing interest as therein provided; and,

      WHEREAS, Pledgor and Pledgee have agreed that Pledgor and Pledgee will

shares of the common stock of American Medical Technologies, Inc. (which shares
are hereinafter referred to at times as the "Pledged Securities") as collateral
security for the due and punctual payment of the Note; and,

      NOW THEREFORE, in consideration of the mutual promises and covenants
contained herein, and Ten Dollars ($10.00) and other good and valuable
consideration, the receipt whereof is hereby acknowledged, the parties hereto
agree as follows:

      1. PLEDGE. As security for the due performance and observation by the
         Pledgor of its continuing obligations with respect to the terms of the
         Note, Pledgor hereby pledges and grants a security interest to Pledgee
         in the Pledged Securities (said Pledged Securities being hereinafter at
         times referred to as the "Collateral") and has duly endorsed in blank
         to the Pledgee a Stock Power covering all such shares. The Pledgee
         shall hold the Pledged Securities as security for the payment by the
         Pledgor of the Note, all in accordance with the applicable terms and
         provisions hereof and of the Note. The Pledgee agrees that Pledgee
         shall not encumber or dispose of all or any part of the Pledged
         Securities except in accordance with the provisions of this Pledge
         Agreement.

      2. REPRESENTATIONS OF PLEDGOR. The Pledgor warrants and represents that
         (i) there are no restrictions upon the transfer of any of the Pledged
         Securities, other than may appear on the face of the certificate(s),
         (ii) the Pledged Securities are not subject to any encumbrances or
         obligations, except as described or referred to herein and in the Note,
         and (iii) the Pledgor has the right to transfer such shares free of any
         encumbrance or obligation and without obtaining the consents of any
         other persons.

      3. DIVIDENDS. The parties hereto do not expect that the issuer of the
         Pledged Securities will pay any cash dividends during the term of this
         pledge; however, should any cash dividends or other distributions be
         received by Pledgor during the 
<PAGE>
         existence of this pledge, the same shall be forthwith delivered to the 
         Pledgee.

      4. VOTING RIGHTS. During the term of this Pledge Agreement and so long as
         the Pledgor is not in default and/or breach in the performance of any
         of the terms of this Pledge Agreement or of the Note, Pledgor shall
         have the right to vote the Pledged Securities on all corporate
         questions as a shareholder of the issuer and, if a need shall arise,
         Pledgee shall execute due and timely proxies in favor of Pledgor to
         this end.

      5. STOCK ADJUSTMENTS. In the event that, during the term of this Pledge,
         any stock dividend, reclassification, readjustment or other change is
         declared or made in the capital stock of the issuer of the Pledged
         Securities, all new, substituted and additional shares, or other
         securities, issued by reason of any such change, shall be held by the
         Pledgee under the terms of this Pledge Agreement in the manner as the
         shares of stock originally pledged hereunder.

      6. TERMINATION OF AGREEMENT. Upon payment in full of all principal and
         interest under the provisions of the Note, the Pledgee shall deliver to
         Pledgor all the shares of the Pledged Securities then in the Pledgee's
         possession, free and clear from the encumbrance created by the
         provisions of this Pledge Agreement and this Pledge Agreement shall
