discretion lend to the Borrower a total principal amount not to exceed the
Maximum Loan Amount (the "Revolving Loan") for working capital to be used in the
operation of the Borrower's business and to issue letters of credit. The
Revolving Loan shall be evidenced by and payable in accordance with the terms of
a promissory note in the face amount of the Maximum Loan Amount (the "Revolving
Note"). The Revolving Note shall evidence the outstanding principal balance of
the Revolving Loan, as it may change from time to time. ADVANCES HEREUNDER ARE
DISCRETIONARY WITH THE BANK AND THE OUTSTANDING PRINCIPAL BALANCE TOGETHER WITH
ALL ACCRUED AND UNPAID INTEREST UNDER THE REVOLVING LOAN, OR SO MUCH THEREOF AS
MAY BE ADVANCED, SHALL BE PAYABLE IN FULL ON THE MATURITY DATE. Advances under
the Revolving Loan shall be subject to the following terms:

                             (a) Advances of proceeds of the Revolving Loan plus
any outstanding letters of credit issued by the Bank shall be limited to the
lesser of the Maximum Loan Amount or the Borrowing Base.

                             (b) Should there occur any overdraft of any deposit
account maintained by the Borrower with the Bank, the Bank may, at its option,
disburse funds (whether or not in excess of the Maximum Loan Amount) to
eliminate such overdraft and such disbursement shall be deemed an Advance of
Loan proceeds hereunder entitled to all of the benefits of the Loan Documents.
Nothing herein shall be deemed an authorization of or consent to the creation of
an overdraft in any account or create any obligations on the part of the Bank;

                             (c) All Advances by the Bank to or for the account
of the Borrower, whether or not in excess of the Maximum Loan Amount, shall be
considered part of the Indebtedness under the Revolving Note, and shall bear
interest as provided in the Revolving Note and herein, and shall be entitled to
all rights and benefits hereunder and under all other Loan Documents; and


                                       14
<PAGE>   19
                             (d) The Borrower shall not request and the Bank
will not be required to consider requests for Advances after May 31, 1998;
provided that the Bank may in its discretion extend such date in writing and
further provided that the repayment obligations of the Borrower for Advances
made by the Bank after such date (as it may be extended) shall be binding on the
Borrower and any other persons liable for any Indebtedness to the same extent as
obligations with respect to Advances made prior to such date.

                  3.2 Limitations on Advances. The outstanding balance of the
Revolving Loan may increase and decrease from time to time, and Advances
thereunder may be repaid and reborrowed, but the total of Advances outstanding
at any one time under the Revolving Loan, plus any outstanding letters of credit
issued by the Bank, shall never exceed the lesser of:

                             (a) The Maximum Loan Amount; or

                             (b) The "Borrowing Base," which shall be equal to
Sixty Percent (60%) of Eligible Accounts. Notwithstanding anything to the
contrary, at no time shall the Advances outstanding together with any letters of
credit issued and outstanding by the Bank exceed sixty percent (60%) of the
Eligible Accounts. The Borrower shall immediately pay to the Bank any amount by
which the Revolving Loan exceeds the Borrowing Base or the Maximum Loan Amount,
whichever is less. The Bank may, in its discretion, make, or permit to remain
outstanding, Advances to the Borrower in excess of the Borrowing Base and/or the
Maximum Loan Amount and all such amounts shall be part of the Revolving Loan and
Indebtedness, shall bear interest as provided in the Note, shall be payable on
demand and shall be entitled to all rights provided for herein, and in all of
the other Loan Documents.

                  3.3        Manner of Borrowing and Disbursement.

                             (a) Choice of Interest Rate. Borrower may, in
accordance with and subject to the terms and conditions of this Section 3.3,
select either the Prime Rate Basis interest rate or the LIBOR Basis interest
rate to apply to the amount outstanding under the Note. Only one interest rate
shall be applicable to the Note at any one time, and Borrower may not select
portions of the 


                                       15
<PAGE>   20
Note to be subject to differing interest rates. If a LIBOR Basis interest rate
is selected, such rate shall apply for the duration of the Interest Period
selected. Notices of any selection, conversion, or continuation of an interest
rate must be provided to Bank three (3) business days prior to the date of the
selection, conversion, or continuation of such interest rate. All such notices
shall be by telephone or telecopier, confirmed immediately in writing,
specifying, within the restrictions specified herein, the date of such
selection, conversion, or continuation, whether the interest rate is to be based
on the Prime Rate Basis or the LIBOR Basis. Each notice of selection,
conversion, or continuation shall be irrevocable and binding on Borrower.

                             (b) Failure to Select. If Borrower shall fail to
give a notice of selection, conversion, or continuation with respect to the
amount outstanding under the Note prior to the end of any Interest Period
applicable thereto as provided in subparagraph (b) hereof, or if there has
otherwise been no interest rate selected for amounts outstanding, then the
interest rate shall automatically convert to the Prime Rate Basis until such
time as Borrower shall select an applicable interest rate in accordance with the
provisions hereof.


                             (c) Disbursement of Advances. The Lender shall
disburse the Advances to the Borrower by depositing such funds into the
Borrower's operating account with the Bank or disbursing such funds as otherwise
directed in writing by the Borrower if the terms and conditions of this
Agreement have been satisfied to Lender's satisfaction.

                  3.4        Interest.

                             (a) On Prime Rate Advances. Interest on each Prime
Rate Advance shall be computed on the basis of a year of 360 days for the actual
number of days elapsed (including the first day but excluding the last day) and
shall be payable at the Prime Rate Basis for such Advance. Interest on Prime
Rate Advances then outstanding shall also be due and payable on the Maturity
Date.

                             (b) On LIBOR Advances. Interest on each LIBOR
Advance shall be computed on the basis of a 360-day year for the actual number
of days elapsed (including the first day but


                                       16
<PAGE>   21
excluding the last day) and shall be payable, to the extent not previously paid,
at the LIBOR Basis for such Advance. Interest on LIBOR Advances then outstanding
shall also be due and payable on the Maturity Date.

                             (d) Interest Upon Default. Upon the occurrence of
an Event of Default (including notice, if any, for such to occur), interest on
the outstanding principal balance of the Advances shall accrue at the Default
Rate from the date of such Event of Default. Such interest shall be payable on
the earlier of demand, each date interest is payable or the Maturity Date and
shall accrue until the earlier of (i) waiver or cure of the applicable Event of
Default, (ii) written agreement by the Lender to rescind the charging of
interest at the Default Rate, or (iii) payment in full of the Indebtedness. The
Lender shall not be required to (a) accelerate the maturity of the Loan, (b)
exercise any other rights or remedies under the Loan Documents, or (c) give
notice to the Borrower of the decision to charge interest on the Loan at the
Default Rate in accordance herewith prior to or in conjunction with the
effective date of the decision to charge interest at the Default Rate.

                             (e) Maximum Number of Interest Periods. Under no
circumstances may the Borrower select an Interest Period for LIBOR Advance if as
a result thereof, more than three (3) different Interest Periods would be
outstanding at any one time for Advances.

                  3.5        Prepayment.

                             (a) Optional Prepayments. The principal amount of
any Prime Rate Advance may be prepaid in full or in part at any time, without
penalty for such Advance, upon one (1) Business Day's prior written notice to
the Bank of such prepayment. LIBOR Advances may be prepaid upon three (3)
Business Days prior written notice to the Bank; provided, that the Borrower
shall reimburse the Lender, on the earlier of demand or the Maturity Date, for
any loss or out-of-pocket expense incurred by the Lender, in connection with
such prepayment, as set forth in Section 3.11 hereof, including without
limitation, any breakage costs. Any notice of prepayment shall be irrevocable
and all amounts prepaid on the Loan shall be applied first to interest and fees
and other amounts due hereunder, and then to principal. Prepayments of Advances,
under this subsection shall be in principal amounts of not less than $100,000.00
and in integral multiples of $100,000.00.


                                       17
<PAGE>   22
                             (b) Application of Prepayments. In the event the
Borrower does not specify the Advance to which a prepayment is to be applied,
such prepayment shall be applied, First, to Prime Rate Advances, to the full
extent thereof, and Second, to LIBOR Advances to the full extent thereof.

                  3.6 Repayment. All Indebtedness of the Borrower then
outstanding under the Note shall be due and payable upon the Maturity Date.


                  3.7 Note. The Loan shall be repayable in accordance with the
terms and provisions set forth herein and shall be evidenced by the Note.

                  3.8 Manner of Payment.

Maturity Date.

                             (b) Each payment (including any prepayment) by the
Borrower on account of the principal of or interest on the Loan, and any other
amount owed to the Lender under this Agreement, the Note or the other Loan
Documents, shall be made prior to 12:00 noon (Eastern time) on the date

Lender in lawful money of the United States of America in immediately available

Loan Documents; and Seventh, upon satisfaction in full of the Loan, to the
Borrower or as otherwise required by law.

                             3.10 Yield Equivalency. In the event that after the
date of the execution hereof (a) the enactment or adoption of, or any change in,
any law, rule, regulation, treaty, guideline or directive (whether or not having
the force of law), or the interpretation or enforcement of any of the foregoing
by any court, central bank, administrative or governmental authority charged
with the administration thereof shall either (i) impose, modify or deem
applicable any reserve, deposit, insurance premium, assessment, fee, capital
requirement, or tax; or (ii) impose any other condition in connection with any
of the Loan, or (b) the Lender shall, in good faith, voluntarily impose, modify
or deem applicable to itself any reserve, deposit, insurance premium,
assessment, fee, capital requirement or similar requirement applicable to the
Loan at the request or the direction (whether or not having the force of law) of
any Court, central bank, administrative or governmental authority, and the
result of any of the foregoing shall be to increase the cost to the Lender of
extending, issuing or maintaining the Loan or to reduce any amount (or the
effective return on any amount) received or receivable by the Lender in
connection with the Loan (which increase in cost or reduction in yield shall be
the result of the Lender's reasonable allocation, in a nondiscriminatory manner
among borrowers having obligations to the Lender similar to those of the
Borrower, of the aggregate of such cost increases or yield reductions resulting
from such event), then, upon written demand by the Lender, the Borrower shall
promptly pay to the Lender, additional amounts which shall be sufficient to
compensate the Lender for all such increased costs or reductions in yield.

                  3.11       Reimbursement.

                             (a) In the event the Borrower shall (i) fail to
borrow any LIBOR Advance after having given notice of its intention to borrow in
accordance with Section 3.3 hereof (whether by reason of the election of the
Borrower not to proceed or the non- fulfillment of any of the conditions set
forth in Section 4), or (ii) pay any LIBOR prepayment pursuant to Sections 3.5,
3.13 and 3.14 hereof) the Borrower agrees to pay to the Lender, upon the earlier
of Lender's demand or the Maturity Date, an amount sufficient to compensate the
Lender (and its respective participants and assignees permitted hereunder) for
all losses and out-of-pocket expenses directly relating to such failure or
prepayment, as applicable (including, without limitation, breakage costs) as
determined by the Lender on the basis of its own standard practices.
Determination of the amount of such losses and out-of-pocket expenses by the
Lender, absent manifest error, shall be presumed correct.

                             (b) In the case of a LIBOR Advance, such loss or
expense subject to reimbursement shall include, without limitation, an amount
equal to the present value of the excess, if any, as reasonably determined by
the Lender, of (a) the amount of interest that would have accrued on the
principal amount so prepaid or not borrowed for the period from the date of such
prepayment or failure to borrow (such date being hereinafter referred to as the
"Breakage Date") to the last day of the then current Interest Period for such
Advance (or, in the case of a failure to borrow, the Interest Period for such
Advance that would have commenced on the date of such failure) at the rate of
interest applicable to such Advance under the terms of this Agreement over (b)
the amount of interest that Lender would have earned had it invested the entire
amount of funds so prepaid or the entire amount of funds acquired to effect,
fund or maintain the Loan not borrowed, as the case may be, in U.S. Government
Treasury Securities with a maturity comparable to such period or Interest
Period. The present value of such excess shall be calculated by discounting such
excess from the end of such period or Interest Period to the Breakage Date at
the interest rate expressly borne by such U.S. Government Treasury Securities
or, if none, the effective interest rate on such securities. 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 any Advance in any manner it sees
fit; it being 


                                       20
<PAGE>   25
understood, however, that for purposes of this Agreement, all determinations
hereunder shall be made as if Lender had actually funded and maintained each
LIBOR Advance (whether or not the Lender shall have granted any participations
in such Loan).

                  3.12 LIBOR Unavailable. Notwithstanding anything contained
herein which may be construed to the contrary, if with respect to any proposed
LIBOR Advance for any Interest Period, the Lender determines that deposits in
dollars (in the applicable amount) are not being offered to the Lender in the
relevant market for such Interest Period, the Lender shall forthwith give notice
thereof to the Borrower, whereupon until the Lender notifies the Borrower that
the circumstances giving rise to such situation no longer exist, the obligations
of the Lenders to make LIBOR Advances shall be suspended.

                  3.13 Illegality. If any applicable law, rule or regulation, or
any change therein, or any interpretation or change in interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by the Lender with any request or directive (whether or not having the force of
law) of any such authority, central bank or comparable agency, shall make it
unlawful or impossible for the Lender to make, maintain or fund any LIBOR
Advance and the Lender shall forthwith give notice thereof to the Borrower. Upon
receipt of such notice, notwithstanding anything to the contrary, the Borrower
shall repay in full the then outstanding principal amount of each affected
portion of any LIBOR Advance together with accrued interest thereon along with
any reimbursement required under Section 3.11 hereof, either (a) on the last day
of the then current Interest Period applicable to such LIBOR Advance if the
Lender may lawfully continue to maintain and fund its portion of such Advance to
such day or (b) immediately if such Lender may not lawfully continue to fund and
maintain its portion of such Advance to such day. Concurrently with repaying
each affected portion of any LIBOR Advance, notwithstanding anything to the
contrary, the Borrower shall borrow a Prime Rate Advance from the Lender, and
the Lender shall make such Advance in an amount such that the outstanding
principal amount of the Note shall equal the outstanding principal amount of the
Note held by the Lender immediately prior to such repayment.

                  3.14       Increased Costs.

                             (a) If any applicable law, rule or regulation, or
any change therein, or any interpretation or change in interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof or compliance
by any Lender with any request or directive (whether or not having the force of
law) of any such authority, central bank or comparable agency:

                                    (i) shall subject the Lender to any tax,
duty or other charge with respect to its obligation to fund its portion of any
LIBOR Advances, or any LIBOR Advances outstanding, or shall change the basis of
taxation of payments to the Lender of the principal of or interest on its
portion of any LIBOR Advances or in respect of any other amounts due under this
Agreement, in respect of LIBOR Advances, or its obligation to convert or
continue any LIBOR Advances, as applicable (except for changes in the rate of
tax on the overall net income of the Lender); or

                                    (ii) shall impose, modify or deem applicable
any reserve (including, without limitation, any imposed by the Board of
Governors of the Federal Reserve System), special deposit, capital adequacy,
assessment or other requirement or condition against assets of, deposits with or
for the account of, or commitments or credit extended by, the Lender or shall
impose on the Lender or the London Interbank Borrowing Market any other
condition affecting its obligation to convert or continue such LIBOR Advances,
or LIBOR Advances outstanding; and the result of any of the foregoing is to
increase the cost to the Lender of making or maintaining such LIBOR Advances or
to reduce the amount of any sum received or receivable by the Lender under this
Agreement or under the Note with respect thereto, then, on the earlier of demand
by the Lender or the Maturity Date, the Borrower agrees to pay to the Lender
such additional amount or amounts as will compensate the Lender for such
increased costs.

                  Any additional amounts payable by the Borrower pursuant to
this Section 3.14 shall be added to the Indebtedness hereunder.


                                       22
<PAGE>   27
                             (b) A certificate of the Lender claiming
compensation under this Section 3.14 and setting forth the additional amount or
amounts to be paid to it hereunder and calculations therefor shall be presumed
correct in the absence of manifest error. In determining such amount, the Lender
may use any reasonable averaging and attribution methods. If the Lender demands
compensation under this Section 3.14, the Borrower may at any time, upon at
least five (5) Business Days' prior notice to the Lender, convert in full the
then outstanding affected portions of any LIBOR Advances to a Prime Rate
Advance, together with accrued interest thereon to the date of prepayment, along
with any reimbursement required under this Section or Section 3.11 hereof.
Concurrently with conversion, such portions of any LIBOR Advances, the Borrower
shall borrow a Prime Rate Advance, from the Lender, and the Lender shall make
such Advance in an amount such that the outstanding principal amount of the Note
shall equal the outstanding principal amount of the Note immediately prior to
such prepayment.

                  3.15 Effect on Other Advances. If notice has been given
pursuant to Sections 3.12, 3.13 or 3.14 suspending the obligation of the Lender
to make any LIBOR Advances, or requiring affected portions of LIBOR Advances of
the Lender to be converted, then, unless and until the Lender notifies the
Borrower that the circumstances giving rise to such repayment no longer apply,
all portions of Advances which would otherwise be made by such Lender as
portions of LIBOR Advances shall be made instead as Prime Rate Advances.


                  3.16 Special Loan Account. The Borrower shall establish and
maintain with the Bank, during the term of the Loan, a demand deposit account
(the "Special Loan Account") into which the Borrower shall deposit, as received,
all proceeds from the sale of Inventory and collection of Accounts in the form
of checks, drafts, cash or the like.

                  3.17 Debit for Interest and Expenses. The Bank may debit the
Special Loan Account and/or make Advances to the Borrower (whether or not in
excess of the Maximum Loan Amount and/or the Borrowing Base) and apply such
amounts to the payment of interest, fees, expenses and other amounts to which
the Bank may be entitled

 

                                       23
<PAGE>   28
from time to time and the Bank is hereby irrevocably authorized to do so without
consent of the Borrower.

                  3.18 Sales Tax. The Borrower shall notify the Bank if any
Account includes any sales or other similar tax and the Bank may, but shall not
be obligated to, remit any such taxes directly to the taxing authority and make
Advances or charge the Special Loan Account therefor. In no event shall the Bank
be liable for any such taxes.

                  3.19 Letters of Credit; Banker's Acceptances.

                             (a) At its discretion the Bank may from time to
time issue, extend or renew letters of credit and banker's acceptances for the
account of the Borrower or its Subsidiaries. The availability of Advances under
the Revolving Loan shall be reduced by outstanding obligations of the Bank under
any letters of credit and banker's acceptances. All payments made by the Bank
under any such letters of credit or banker's acceptances (whether or not the
Borrower is the account party or drawer) and all fees, commissions, discounts
and other amounts owed or to be owed to the Bank in connection therewith, shall
be deemed to be Advances under the Revolving Note, and shall be repaid on
demand. The Borrower shall complete and sign such applications and supplemental
agreements and provide such other documentation as the Bank may require. The
form and substance of all letters of credit and acceptances, including
expiration dates, shall be subject to the Bank's approval. The Bank may charge a
fee or commission for issuance, renewal or extension of a letter of credit or
acceptance. The Borrower unconditionally guarantees all obligations of any
Subsidiary with respect to letters of credit issued by the Bank for the account
of such Subsidiary and all acceptances of any Subsidiaries' drafts. If the Bank
should demand payment of the Revolving Loan, the Borrower shall, on demand,
deliver to the Bank good funds equal to 100% of the Bank's maximum liability
under all outstanding letters of credit and banker's acceptances, to be held as
cash collateral for the Borrower's reimbursement obligations and other
Indebtedness.

                             (b) In order to induce Bank to issue letters of
credit and banker's acceptances, the Borrower agrees that neither Bank nor its
correspondents or agents shall be liable or responsible for, and the Borrower's
unconditional obligation to




                                       24
<PAGE>   29
reimburse Bank for the obligations shall not be affected by, any event or
circumstance, including without limitation: (i) the validity, enforceability,
genuineness or sufficiency of documents or of any endorsement thereon existing
in connection with any letter of credit or banker's acceptance, even if such
documents should in fact prove in any or all respects to be invalid,
unenforceable, insufficient, fraudulent or forged; (ii) any breach of contract
or other dispute between the Borrower and any beneficiary of a letter of credit
or holder of a draft accepted by the Bank; (iii) payment by the Bank upon
presentation of a draft or documents which do not comply in any respect with the
terms of such letter of credit or draft; (iv) loss of or damage to any
collateral; (v) the invalidity or insufficiency of any endorsements: (vi) delay
in giving or failure to give notice of arrival or any other notice; (vii)
failure of any instrument to bear any reference or adequate reference to the
letter of credit or draft or to documents to accompany any instrument at
negotiation; or (viii) failure of any person to note the amount of any payment
on the reverse of the letter of credit or to surrender to or take up the letter
of credit or draft or to forward documents in the manner required by the letter
of credit or draft; or (ix) any other matter whatsoever excepting only with
respect to each of the foregoing items the gross negligence (or negligence as to
(iii) above) or willful misconduct of the Bank or its agent. The Borrower agrees
that any action taken or permitted to be taken by the Bank or its agent under or
in connection with any letter of credit or banker's acceptance, including
related drafts, documents, or property, unless constituting gross negligence or
willful misconduct (or negligence as to (iii) above) on the part of the Bank or
its agent, shall be binding on the Borrower and shall not create any resulting
liability to the Borrower on the part of the Bank or its agent. The Borrower
will immediately examine (a) a copy of the letter of credit (and any amendments
thereof) or draft sent to it by the Bank or its agent, and the Borrower will
immediately notify the Bank in writing of any claim or irregularity.

                             (c) Any letter of credit issued hereunder shall be
governed by the Uniform Customs of Practice for Documentary Credit (1983 Rev.),
International Chamber of Commerce Publication No. 400, as revised from time to
time, except to the extent that the terms of such publication would limit or
diminish rights granted the Bank hereunder or in any other Loan Document.

                  6.2 Remedies. If any Default shall occur, the Bank may,
without notice to the Borrower, at its option, withhold further Advances to the
Borrower of proceeds of the Loan. Should (a) any Event of Default under Section

<PAGE>   41
demanded), bring suit against the Borrower to collect the Indebtedness, exercise
any remedy available to the Bank hereunder and take any action or exercise any
remedy provided herein or in any other Loan Document or under applicable law.
Bank agrees that it will apply the Default Rate to any Event of Default under

to Borrower of such default. Notwithstanding the foregoing, Bank may exercise
all of its rights and remedies immediately upon a default under Section 6.1(c)
(including acceleration of the Loan) and Bank shall not be required to wait
until the foregoing thirty (30) day notice period has expired to exercise all of
its rights and remedies. No remedy shall be exclusive of other remedies or
impair the right of the Bank to exercise any other remedies.

                  6.3 Receiver. In addition to any other remedy available to it,
the Bank shall have the absolute right, upon the occurrence of an Event of
Default, to seek and obtain the appointment of a receiver to take possession of

any check or draft or take other action necessary to obtain such funds.

                  6.5 Other Rights. The Borrower authorizes the Bank without
affecting the Borrower's obligations hereunder or under any other Loan Document
from time to time (i) to take from any party and hold additional collateral or
guaranties for the payment of the Indebtedness or any part thereof, and to
exchange, enforce or release such collateral or guaranty of payment of the
Indebtedness or any part thereof and to release or substitute any endorser or
guarantor or any party who has given any security interest in any collateral as
security for the payment of the Indebtedness or any part thereof or any party in
any way obligated to pay the Indebtedness or any 


                                       37
<PAGE>   42
part thereof; and (ii) upon the occurrence of any Event of Default to direct the
manner of the disposition of any collateral and the enforcement of any
endorsements, guaranties, letters of credit or other security relating to the
Indebtedness or any part thereof as the Bank in its sole discretion may
determine.

                  6.6 Waiver of Marshalling. The Borrower hereby waives any
right it may have to require marshalling of its assets.

                  6.7 Waiver of Automatic Stay. The Borrower hereby waives the

enforcement and collection notwithstanding the filing of a petition in
bankruptcy.

         7.       MISCELLANEOUS.

                  7.1 No Waiver, Remedies Cumulative. No failure on the part of
the Bank to exercise, and no delay in exercising, any right hereunder or under
any other Loan Document shall operate as a waiver thereof, nor shall any single
or partial exercise of any right hereunder preclude any other or further
exercise thereof or the exercise of any other right. The remedies herein
provided are cumulative and are in addition to any other remedies provided by
law, any Loan Document or otherwise.

                  7.2 Survival of Representations. All representations and
warranties made herein shall survive the making of the Loan hereunder and the
delivery of the Note, and shall continue in full force and effect so long as any
Indebtedness is outstanding, there exists any commitment by the Bank to the
Borrower, and until this Agreement is formally terminated in writing.

                  7.3 Expenses. Whether or not the Loan herein provided for
shall be made, the Borrower shall pay all reasonable costs and expenses in
connection with the preparation, execution, delivery, amendment and enforcement
of this Agreement and any Loan Document, including the reasonable fees and
disbursements of counsel for the Bank in connection therewith, whether suit be
brought or not and whether incurred at trial or on appeal. Borrower shall pay
Bank a facility fee of $15,000.00 upon execution of this Agreement and an
additional facility fee of $15,000.00 on April 30, 1997. In


                                       38
<PAGE>   43
addition, the Borrower agrees to pay and save the Bank harmless against any
liability for payment of any state documentary stamp taxes, intangible taxes or
similar taxes (including interest or penalties, if any) which may now or
hereafter be determined to be payable in respect to the execution, delivery or
recording of any Loan Document or the making of any Advance, whether originally
thought to be due or not, and regardless of any mistake of fact or law on the
part of the Bank or the Borrower with respect to the applicability of such tax.
The provisions of this section shall survive payment in full of the Loan and
termination of this Agreement.

investigation of any kind by Bank as to the use of such proceeds. Each of the
Borrowers confirms that it will be directly or indirectly benefited by each and
every loan, disbursement, or advance subject to the provisions of this
Agreement.

                  c. No invalidity, irregularity, or unenforceability of all or
any part of the obligations of the other Borrower subject to this Agreement or
otherwise to Bank or insufficiency, invalidity, irregularity, or
unenforceability of any security or guaranty for the obligations of Borrowers
hereunder shall affect, impair, or be a defense to the obligations of either of
the Borrowers to Bank subject to this Agreement.

                  d. Each of the Borrowers waives any duty on Bank's part
(should such duty exist) to disclose to such Borrower any matter, fact, or thing
related to the business, operations, or condition (financial or otherwise) of
the other Borrower or its affiliates or property, whether now or hereafter known
by Bank. Bank shall have no duty to disclose to such Borrower the
difference, if any, between the terms which were initially proposed for the
obligations subject to this Agreement and which were presumably disclosed to, or
known by such Borrower, and the actual terms of the obligations, as executed,
including but not limited to the existence or amount of guaranties or security
therefor. Each of the Borrowers agrees that any lack of knowledge of such
Borrower as to such matters will not impair, release, or otherwise affect the
obligations of such Borrower subject to this Agreement.

                  e. Any and all claims of either of the Borrowers against the
other Borrower or any of its property, whether through subrogation to the rights
of Bank hereunder or otherwise, shall be subordinate and subject in right of
payment to the prior payment in full of the obligations subject to this
Agreement.

                  f. If either of the Borrowers is held to be an accommodation
party with respect to a loan or portion of a loan hereunder, or is otherwise
held not to be primarily liable thereunder, said party (who is held not to be
primarily liable) agrees that it absolutely and unconditionally guarantees the
payment of all loans hereunder whether now or hereafter made regardless of the
enforceability of such loans against any other party thereto.

                  7.13 Other Provisions. Any other or additional terms and
conditions set forth in Exhibit 8.13 (if any) are hereby incorporated herein.

                  7.14 Waiver of Jury Trial. THE BORROWER AND THE BANK HEREBY
KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE THE RIGHT EITHER OF THEM MAY HAVE
TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED UPON THIS AGREEMENT OR
ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT AND ANY OTHER LOAN
DOCUMENT AND ANY OTHER AGREEMENT CONTEMPLATED TO BE EXECUTED IN CONJUNCTION
HEREWITH, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER
VERBAL OR WRITTEN) OR ACTIONS OF ANY PARTY. THIS

                    HAZARDOUS MATERIALS UTILIZED BY BORROWER

                   BORROWER'S HAZARDOUS SUBSTANCES PROCEDURES

   1.    Definition of Hazardous Materials. A material and/or waste (solid,
         liquid or gaseous) shall be considered "Hazardous" if:

         A.       It appears on one or more hazardous substance lists published
                  by the EPA under the Resource Conservation and Recovery Act
                  (RCRA) and SARA Title III, Part 313.

         B.       It is acutely hazardous waste as defined by the EPA's 40
                  C.F.R. Parts 261-262.

         C.       It exhibits any of the following characteristics as defined by
                  NFPA regulations and the substances MSDS:

                  (1)      Ignitibility. The material or waste is easily
                           combustible or flammable.

                  (2)      Corrosivity. The material or waste is capable of
                           causing slow chemical and/or electrochemical reaction
                           between a metal and it's environment (for example,
                           the rusting of iron). Ultimately, dissolving metals
                           or other materials and burns the skin.

                  (3)      Reactivity. The material or waste is "explosive,"
                           unstable, or undergoes rapid or violent chemical
                           reaction with water or other materials.

                  (4)      Toxicity. The material or waste has the potential to
                           release toxic substances that can pose a hazard to
                           human health or the environment.

2.       Hazardous Materials Inventory.  The following is an inventory of all
         hazardous materials handled, stored, accumulated, treated and disposed
         within the confines of Boca Research.

         A.       IEM Fusion NCR-P-7X-3 Soldering Paste (Tin, Lead)

         B.       Amicon D-124F (Epoxy Adhesive)


                                       54
<PAGE>   59
         C.       Centari Acrylic Enamel

         D.       Water soluble, neutral flux solution which is completely
                  biodegradable and a non-irritant

         E.       Gold Solution (Cyanide Salt-Amine)

         F.       Loctite 3348 Chipbonder (Epoxy Adhesive)

         G.       Loctite 454 Surface Insensitive Instant Adhesive (Ethyl
                  Cyanoacrylate, Amorphous Silica, Hydroquinone)

         H.       Nickel Acid Solution (Nickel Sulfate, Formic Acid)

         I.       SCM Metal Products Soldering Paste (TEA, Tin, Lead,
                  Triethanolamine, Silver)

         J.       AP Grease (Naphthionic distillate)

3.       Hazardous Materials Handling and Use. All hazardous material and waste
         are handled and used in accordance with all Occupational Health and
         Safety Association (OSHA) rules and regulations. All employees have
         been provided on-the-job training regarding personal protective
         equipment, safe handling, storage and disposal of hazardous materials
         and waste.

4.       Hazardous Materials and Waste Management.

         A.       Hazardous Materials Labeling. All hazardous materials are
                  labeled in accordance with Department of Transportation (DOT)
                  and the National Fire Protection (NFPA).

         B.       Hazardous Materials Containment. Hazardous waste are placed in
                  containers appropriate for the type of hazardous waste
                  generated and the type of treatment and/or disposal method
                  anticipated.

                  All containers designated for Hazardous Materials/Waste
                  containment are constructed of a smooth material that is
                  impervious to liquids and is capable of being maintained in a
                  sanitary condition.

         C.       Hazardous Materials Storage and Accumulation. Hazardous
                  materials storage and accumulation areas are located away from
                  public access

                                       55
<PAGE>   60
                  and general traffic flow patterns. Furthermore,
                  the area is restricted and secured against authorized
                  personnel.

                  (1)      Flammables. Flammable materials are stored in a cool,
                           dry, well-ventilated area away from any possible
                           ignition sources. Highly flammable materials are kept
                           in an area separate from oxidizing agents.

                  (2)      Oxidizers. All chemicals that combine or mix with
                           oxygen are stored away from liquids or low flash
                           point.

                  (3)      Corrosives. Corrosive materials are stored in a cool,
                           well-ventilated area (above their freezing point).
                           Furthermore, corrosives are isolated from other
                           materials since they tend to corrode everything that
                           is stored with them.

                  (4)      Acids and Bases. Acids and Bases are stored in a
                           cool, dry, well-ventilated area.

                  (5)      Highly Volatile Substances. Materials that are highly
                           toxic or that can decompose into toxic components
                           from contact with heat, moisture, acids or acid fumes
                           will be stored in a cool, well-ventilated area out of
                           the direct rays of the sun. Incompatible toxic
                           materials will be isolated from each other.

                  (6)      Solder Pastes. All solder pastes are covered by Boca
                           Research in a solid, physical state which is easily
                           contained in impermeable, sealed containers and
                           accumulated in a refrigerator for future reclamation.

         D.       Hazardous Waste Reclamation and/or Disposal. All hazardous
                  waste generated by Boca Research is immediately disposed
                  according to federal, state and local regulations. Hazardous
                  waste that cannot be treated or disposed immediately after it
                  is generated is accumulated at its point of origin in a
                  storage area designated for hazardous waste accumulation.

                  (1)      Solder Paste and Dross. 100% of all excess solder
                           paste (dross) generated by the Wave Solderer is
                           immediately contained and accumulated for off-site
                           reclamation.

<PAGE>   61
                  (2)      Containment Residuals. Empty containers lined with a
                           residue of hazardous material/waste are returned to
                           the manufacturer for reclamation.

                  (3)      Waste Water Residuals. Waste water effluent generated
                           by Boca Research that has been contaminated with
                           hazardous waste is passed through a closed loop
                           filtration system. The resulting treated residue can
