Guarantees may be outstanding on the Closing Date. Each Letter of Credit shall

Agreement is scheduled to terminate under Section 3.4 (without regard to any
potential renewal term) and all such Letters of Credit shall be in form and
substance acceptable to Foothill in its sole discretion. If Foothill is
obligated to advance funds under a Letter of Credit, Borrower immediately shall
reimburse such amount to Foothill and, in the absence of such reimbursement, the
amount so advanced immediately and automatically shall be deemed to be an
Advance hereunder and, thereafter, shall bear interest at the rate then
applicable to Advances under Section 2.6.

Foothill to or for Borrower's account, even though this interpretation may be
different from Borrower's own, and Borrower understands and agrees that Foothill
shall not be liable for any error, negligence, or mistake, whether of omission
or commission, in following Borrower's instructions or those contained in the
Letter of Credit or any modifications, amendments, or supplements thereto.

Borrower against such issuing bank. Borrower hereby agrees to indemnify, save,
defend, and hold Foothill harmless with respect to any loss, cost, expense
(including reasonable attorneys fees), or liability incurred by Foothill under
any L/C Guaranty as a result of Foothill's indemnification of any such issuing
bank.

                           (c) Borrower hereby authorizes and directs any bank

Agreement, Borrower agrees to either (i) provide cash collateral to be held by
Foothill in an amount equal to 102% of the maximum amount of Foothill's
obligations under Letters of Credit, or (ii) cause to be delivered to Foothill
releases of all of Foothill's obligations under outstanding Letters of Credit.
At Foothill's discretion, any proceeds of Collateral received by Foothill after
the occurrence and during the continuation of an Event of Default may be held as
the cash collateral required by this Section 2.2(e).

                           (f) If by reason of (i) any change in any applicable
law, treaty, rule, or regulation or any change in the interpretation or
application by any governmental authority of any such applicable law, treaty,
rule, or regulation, or (ii) compliance by the issuing bank or Foothill with any
direction, request, or requirement (irrespective of whether having the force of
law) of any governmental authority or monetary authority including, without

bank or Foothill any other condition regarding any letter of credit, or Letter 
of Credit, as applicable, issued pursuant hereto;

to the issuing bank or Foothill of issuing, making, guaranteeing, or maintaining
any letter of credit, or Letter of Credit, as applicable, or to reduce the
amount receivable in respect thereof by such issuing bank or Foothill, then, and
in any such case, Foothill may, at any time within a reasonable period after the
additional cost is incurred or the amount received is reduced, notify Borrower,
and Borrower shall pay on demand such amounts as the issuing bank or Foothill
may specify to be necessary to compensate the issuing bank or Foothill for such
additional cost or reduced receipt, together with interest on such amount from
the date of such demand until payment in full thereof at the rate set forth in
Section 2.6(a)(i) or (c)(i), as applicable. The determination by the issuing
bank or Foothill, as the case may be, of any amount due pursuant to this Section
2.2(f), as set forth in a certificate setting forth the calculation thereof in
reasonable detail, shall, in the absence of manifest or demonstrable error, be
final and conclusive and binding on all of the parties hereto.

financial statements show that Borrower has a positive Net Income for its 1998
fiscal year, (iii) the average Availability for the forty-five day period
immediately prior to the receipt by Foothill of the audited financial statements
for the 1998 fiscal year of Borrower is equal to or greater than $2,000,000, and
(iv) no Default or Event of Default has occurred and is continuing, then,
effective on the first day that each of the conditions set forth in clauses (i)
through (iv) of this subsection have been satisfied, the foregoing rate shall be
reduced to one-half percentage point (0.5%) above the Reference Rate.

                           (b) Letter of Credit Fee. Borrower shall pay Foothill
a fee (in addition to the charges, commissions, fees, and costs set forth in

                           (c) Default Rate. Upon the occurrence and during the
continuation of an Event of Default, (i) all Obligations (except for undrawn

percentage points (4.0%) above the Reference Rate and (ii) the Letter of Credit
fee provided in Section 2.6(b) shall be increased to four and one-half percent
(4.5%) per annum times the amount of the undrawn Letters of Credit that were
outstanding during the immediately preceding month.

                           (d) Minimum Interest. In no event shall the rate of
interest chargeable hereunder for any day be less than seven percent (7.0%) per
annum. To the extent that interest accrued hereunder at the rate set forth
herein would be less than the foregoing minimum daily rate, the interest rate
chargeable hereunder for such day automatically shall be deemed increased to the
minimum rate. To the extent that interest accrued hereunder at the rate set
forth herein (including the minimum interest rate) would yield less than the
foregoing minimum amount, the interest rate chargeable hereunder for the period
in question automatically shall be deemed increased to that rate that would
result in the minimum amount of interest being accrued and payable hereunder.

                           (e) Payments. Interest and Letter of Credit fees
payable hereunder shall be due and payable, in arrears, on the first day of each

hereunder. Any interest not paid when due shall be compounded and shall 
thereafter accrue interest at the rate then applicable to Advances hereunder.

                           (f) Computation. The Reference Rate as of the date of
this Agreement is eight and one-half percent (8.5%) per annum. In the event the
Reference Rate is changed from time to time hereafter, the applicable rate of
interest hereunder automatically and immediately shall be increased or decreased
by an amount equal to such change in the Reference Rate. All interest and fees
chargeable under the Loan Documents shall be computed on the basis of a 360 day
year for the actual number of days elapsed.

                           (g) Intent to Limit Charges to Maximum Lawful Rate.
In no event shall the interest rate or rates payable under this Agreement, plus
any other amounts paid in connection herewith, exceed the highest rate
permissible under any law that a court of competent jurisdiction shall, in a
final determination, deem applicable. Borrower and Foothill, in executing and
delivering this Agreement, intend legally to agree upon the rate or rates of
interest and manner of payment stated within it; provided, however, that,
anything contained herein to the contrary notwithstanding, if said rate or rates
of interest or manner of payment exceeds the maximum allowable under applicable
law, then, ipso facto as of the date of this Agreement, Borrower is and shall be
liable only for the payment of such maximum as allowed by law, and payment
received from Borrower in excess of such legal maximum, whenever received, shall
be applied to reduce the principal balance of the Obligations to the extent of
such excess.

                  2.7 COLLECTION OF ACCOUNTS. Borrower shall at all times
maintain lockboxes (the "Lockboxes") and, immediately after the Closing Date,
shall instruct all Account Debtors with respect to the Accounts, General
Intangibles, and Negotiable Collateral of Borrower to remit all Collections in
respect thereof to such Lockboxes. Borrower, Foothill, and the Lockbox Banks
shall enter into the Lockbox Agreements, which among other things shall provide
for the opening of a Lockbox Account for the deposit of Collections at a Lockbox
Bank. Borrower agrees that all Collections and other amounts received by
Borrower from any Account Debtor or any other source immediately upon receipt
shall be deposited into a Lockbox Account. No Lockbox Agreement or arrangement
contemplated thereby shall be modified by Borrower without the prior written
consent of Foothill. Upon the terms and subject to the conditions set forth in
the Lockbox Agreements, all amounts received in each Lockbox Account shall be
wired each Business Day into an account (the "Foothill Account") maintained by
Foothill at a depositary selected by Foothill.

                  2.8 CREDITING PAYMENTS; APPLICATION OF COLLECTIONS. The
receipt of any Collections by Foothill (whether from transfers to Foothill by
the Lockbox Banks pursuant to the Lockbox Agreements or otherwise) immediately
shall be applied provisionally to reduce the Obligations outstanding under
Section 2.1, but shall not be considered a payment on account unless such
Collection item is a wire transfer of immediately available federal funds and is
made to the Foothill Account or unless and until such Collection item is honored
when presented for payment. From and after the Closing Date, Foothill shall be
entitled to charge Borrower for three (3) Business Days of `clearance' or
`float' at the rate set forth in Section 2.6(a)(i) or Section 2.6(c)(i), as
applicable, on all Collections that are received by Foothill (regardless of
whether forwarded by the Lockbox Banks to Foothill, whether provisionally
applied to reduce the Obligations under Section 


                                      -19-
<PAGE>   26

2.1, or otherwise). This across-the-board three (3) Business Day clearance 
or float charge on all Collections is acknowledged by the parties to 
constitute an integral aspect of the pricing of Foothill's financing of 
Borrower, and shall apply irrespective of the characterization of whether 
receipts are owned by Borrower or Foothill, and whether or not there are 
any outstanding Advances, the effect of such clearance or float charge 
being the equivalent of charging three (3) Business Days of interest 
on such Collections. Should any Collection item not be honored when
presented for payment, then Borrower shall be deemed not to have made such
payment, and interest shall be recalculated accordingly. Anything to the
contrary contained herein notwithstanding, any Collection item shall be deemed
received by Foothill only if it is received into the Foothill Account on a
Business Day on or before 11:00 a.m. California time. If any Collection item is
received into the Foothill Account on a non-Business Day or after 11:00 a.m.
California time on a Business Day, it shall be deemed to have been received by
Foothill as of the opening of business on the immediately following Business
Day.

                  2.9 DESIGNATED ACCOUNT. Foothill is authorized to make the
Advances and the Letters of Credit, under this Agreement based upon telephonic
or other instructions received from anyone purporting to be an Authorized
Person, or without instructions if pursuant to Section 2.6(e). Borrower agrees
to establish and maintain the Designated Account with the Designated Account
Bank for the purpose of receiving the proceeds of the Advances requested by
Borrower and made by Foothill hereunder. Unless otherwise agreed by Foothill and
Borrower, any Advance requested by Borrower and made by Foothill hereunder shall
be made to the Designated Account.

                  2.10 MAINTENANCE OF LOAN ACCOUNT; STATEMENTS OF OBLIGATIONS.
Foothill shall maintain an account on its books in the name of Borrower (the
"Loan Account") on which Borrower will be charged with all Advances, made by
Foothill to Borrower or for Borrower's account, including, accrued interest,
Foothill Expenses, and any other payment Obligations of Borrower. In accordance
with Section 2.8, the Loan Account will be credited with all payments received
by Foothill from Borrower or for Borrower's account, including all amounts
received in the Foothill Account from any Lockbox Bank. Foothill shall render
statements regarding the Loan Account to Borrower, including principal,
interest, fees, and including an itemization of all charges and expenses
constituting Foothill Expenses owing, and such statements shall be conclusively
presumed to be correct and accurate and constitute an account stated between
Borrower and Foothill unless, within 30 days after receipt thereof by Borrower,
Borrower shall deliver to Foothill written objection thereto describing the
error or errors contained in any such statements.

                  2.11 FEES. Borrower shall pay to Foothill the following 
nonrefundable fees in immediately available funds as follows:

                           (a) Facility Fee. On the Closing Date, a closing fee
of three-quarters of one-percent (0.75%) of the Maximum Revolving Amount and, on
or prior to the effective date of any increase of the Maximum Revolving Amount,
three-quarters of one-percent (0.75%) of such increase;

                           (b) Unused Line Fee. On the first day of each month

Maximum Revolving Amount in effect at such time;

<PAGE>   27

                           (c) Annual Facility Fee. On each anniversary of the
Closing Date, an annual facility fee in an amount equal to one-quarter of one
percent (0.25%) of the Maximum Revolving Amount in effect at such time;

                           (d) Financial Examination, Documentation, and
Appraisal Fees. Foothill's customary fee of $650 per day per examiner, plus
out-of-pocket expenses for each financial analysis and examination (i.e.,
audits) of Borrower performed by personnel employed by Foothill; Foothill's
customary appraisal fee of $1,500 per day per appraiser, plus out-of-pocket
expenses for each appraisal of the Collateral performed by personnel employed by
Foothill; and, the actual charges paid or incurred by Foothill if it elects to
employ the services of one or more third Persons to perform such financial
analyses and examinations (i.e., audits) of Borrower or to appraise the
Collateral; and

                           (e) Servicing Fee. On the first day of each month
during the term of this Agreement, and thereafter so long as any Obligations are
outstanding, a servicing fee in an amount equal to $2,500.

<PAGE>   30

                  3.3 CONDITIONS SUBSEQUENT. As conditions subsequent to initial

set-off in a similar amount), and provide evidence thereof to Foothill.

                  3.4 TERM; AUTOMATIC RENEWAL. This Agreement shall become
effective upon the execution and delivery hereof by Borrower and Foothill and
shall continue in full force and effect for a term ending on the date (the
"Renewal Date") that is three (3) years from the Closing 

                                      -24-
<PAGE>   31



Date and automatically shall be renewed for successive one (1) year periods 
thereafter, unless sooner terminated pursuant to the terms hereof. Either party 
may terminate this Agreement effective on the Renewal Date or on any one (1) 
year anniversary of the Renewal Date by giving the other party at least 90 days
prior written notice. The foregoing notwithstanding, Foothill shall have the 
right to terminate its obligations under this Agreement immediately and without
notice upon the occurrence and during the continuation of an Event of Default.

                  3.5 EFFECT OF TERMINATION. On the date of termination of this
Agreement, all Obligations (including contingent reimbursement obligations of
Borrower with respect to any outstanding Letters of Credit) immediately shall
become due and payable without notice or demand. No termination of this
Agreement, however, shall relieve or discharge Borrower of Borrower's duties,
Obligations, or covenants hereunder, and Foothill's continuing security
interests in the Collateral shall remain in effect until all Obligations have
been fully and finally discharged and Foothill's obligation to provide
additional credit hereunder is terminated. If Borrower has sent a notice of
termination pursuant to the provisions of Section 3.4, but fails to pay the
Obligations in full on the date set forth in said notice, then Foothill may, but
shall not be required to, renew this Agreement for an additional term of one (1)
year.

                  3.6 EARLY TERMINATION BY BORROWER. The provisions of Section
3.4 that allow termination of this Agreement by Borrower only on the Renewal
Date and certain anniversaries thereof notwithstanding, Borrower has the option,
at any time upon 90 days prior written notice to Foothill, to terminate this
Agreement by paying to Foothill, in cash, the Obligations (including an amount
equal to 102% of the undrawn amount of the Letters of Credit), in full, together
with a premium (the "Early Termination Premium") equal to (a) three percent (3%)
of the Maximum Revolving Amount then in effect, if such termination occurs
during the period from the Closing Date through the first anniversary thereof,
(b) two percent (2%) of the Maximum Revolving Amount then in effect, if such
termination occurs during the period from the day after such first anniversary
through the second anniversary of the Closing Date and (c) one percent (1%) of
the Maximum Revolving Amount then in effect, if such termination occurs from the
day after such second anniversary through the day prior to the third anniversary
of the Closing Date.

                  3.7 TERMINATION UPON EVENT OF DEFAULT. If Foothill terminates
this Agreement upon the occurrence of an Event of Default, in view of the
impracticability and extreme difficulty of ascertaining actual damages and by
mutual agreement of the parties as to a reasonable calculation of Foothill's
lost profits as a result thereof, Borrower shall pay to Foothill upon the
effective date of such termination, a premium in an amount equal to the Early
Termination Premium. The Early Termination Premium shall be presumed to be the
amount of damages sustained by Foothill as the result of the early termination
and Borrower agrees that it is reasonable under the circumstances currently
existing. The Early Termination Premium provided for in this Section 3.7 shall
be deemed included in the Obligations.

         4.       CREATION OF SECURITY INTEREST.

                  4.1 GRANT OF SECURITY INTEREST. Borrower hereby grants to
Foothill a continuing security interest in all currently existing and hereafter
acquired or arising Collateral in order to secure prompt repayment of any and
all Obligations and in order to secure prompt 



                                      -25-
<PAGE>   32


performance by Borrower of each of its covenants and duties under the Loan 
Documents. Foothill's security interests in the Collateral shall attach to all 
Collateral without further act on the part of Foothill or Borrower. Anything 
contained in this Agreement or any other Loan Document to the contrary 
notwithstanding, except for the sale of Inventory to buyers in the ordinary 
course of business, Borrower has no authority, express or implied, to dispose 
of any item or portion of the Collateral.

                  4.2 NEGOTIABLE COLLATERAL. In the event that any Collateral,
including proceeds, is evidenced by or consists of Negotiable Collateral,
Borrower, immediately upon the request of Foothill, shall endorse and deliver
physical possession of such Negotiable Collateral to Foothill.

                  4.3 COLLECTION OF ACCOUNTS, GENERAL INTANGIBLES, AND
NEGOTIABLE COLLATERAL. At any time that an Event of Default has occurred and is
continuing, Foothill or Foothill's designee may (a) notify customers or Account
Debtors of Borrower that the Accounts, General Intangibles, or Negotiable
Collateral have been assigned to Foothill or that Foothill has a security
interest therein, and (b) collect the Accounts, General Intangibles, and
Negotiable Collateral directly and charge the collection costs and expenses to
the Loan Account. Borrower agrees that it will hold in trust for Foothill, as
Foothill's trustee, any Collections that it receives and immediately will
deliver said Collections to Foothill in their original form as received by
Borrower.

                  4.4 DELIVERY OF ADDITIONAL DOCUMENTATION REQUIRED. At any time
upon the request of Foothill, Borrower shall execute and deliver to Foothill all
financing statements, continuation financing statements, fixture filings,
security agreements, pledges, assignments, endorsements of certificates of
title, applications for title, affidavits, reports, notices, schedules of
accounts, letters of authority, and all other documents that Foothill reasonably
may request, in form satisfactory to Foothill, to perfect and continue perfected
Foothill's security interests in the Collateral, and in order to fully
consummate all of the transactions contemplated hereby and under the other the
Loan Documents.

                  4.5 POWER OF ATTORNEY. Borrower hereby irrevocably makes,
constitutes, and appoints Foothill (and any of Foothill's officers, employees,
or agents designated by Foothill) as Borrower's true and lawful attorney, with
power to (a) if Borrower refuses to, or fails timely to execute and deliver any
of the documents described in Section 4.4, sign the name of Borrower on any of
the documents described in Section 4.4, (b) at any time that an Event of Default
has occurred and is continuing or Foothill deems itself insecure, sign
Borrower's name on any invoice or bill of lading relating to any Account, drafts
against Account Debtors, schedules and assignments of Accounts, verifications of
Accounts, and notices to Account Debtors, (c) send requests for verification of
Accounts, (d) endorse Borrower's name on any Collection item that may come into
Foothill's possession, (e) at any time that an Event of Default has occurred and
is continuing or Foothill deems itself insecure, notify the post office
authorities to change the address for delivery of Borrower's mail to an address
designated by Foothill, to receive and open all mail addressed to Borrower, and
to retain all mail relating to the Collateral (giving Borrower, upon Borrower's
reasonable request, a reasonable opportunity to review such retained mail) and
forward all other mail to Borrower, (f) at any time that an Event of Default has
occurred and is continuing or Foothill deems itself insecure, make, settle, and

time that an Event of Default has occurred and is continuing or Foothill
deems itself insecure, settle and adjust disputes and claims respecting the
Accounts directly with Account Debtors, for amounts and upon terms that Foothill
determines to be reasonable, and Foothill may cause to be executed and delivered
any documents and releases that Foothill determines to be necessary. The
appointment of Foothill as Borrower's attorney, and each and every one of
Foothill's rights and powers, being coupled with an interest, is irrevocable
until all of the Obligations have been fully and finally repaid and performed
and Foothill's obligation to extend credit hereunder is terminated.

                  4.6 RIGHT TO INSPECT. Foothill (through any of its officers,
employees, or agents) shall have the right, from time to time hereafter to
inspect Borrower's Books and to check, test, and appraise the Collateral in
order to verify Borrower's financial condition or the amount, quality, value,
condition of, or any other matter relating to, the Collateral.

         5.       REPRESENTATIONS AND WARRANTIES.

                  In order to induce Foothill to enter into this Agreement,
Borrower makes the following representations and warranties which shall be true,
correct, and complete in all respects as of the date hereof, and shall be true,
correct, and complete in all respects as of the Closing Date, and at and as of
the date of the making of each Advance or Letter of Credit made thereafter, as
though made on and as of the date of such Advance or Letter of Credit (except to
the extent that such representations and warranties relate solely to an earlier
date) and such representations and warranties shall survive the execution and
delivery of this Agreement:

                  5.1 NO ENCUMBRANCES. Borrower has good and indefeasible title
to the Collateral, free and clear of Liens except for Permitted Liens.

                  5.2 ELIGIBLE ACCOUNTS. The Eligible Accounts are bona fide
existing obligations created by the sale and delivery of Inventory or the
rendition of services to Account Debtors in the ordinary course of Borrower's
business, unconditionally owed to Borrower without defenses, disputes, offsets,
counterclaims, or rights of return or cancellation. The property giving rise to
such Eligible Accounts has been delivered to the Account Debtor, or to the
Account Debtor's agent for immediate shipment to and unconditional acceptance by
the Account Debtor. Borrower has not received notice of actual or imminent
bankruptcy, insolvency, or material impairment of the financial condition of any
Account Debtor regarding any Eligible Account.

                  5.3 INVENTORY. All Inventory is of good and merchantable
quality, free from defects.

                  5.4 EQUIPMENT.  All of the Equipment is used or held for use 
in Borrower's business and is fit for such purposes.

                  5.5 LOCATION OF INVENTORY AND EQUIPMENT. The Inventory and
Equipment are not stored with a bailee, warehouseman, or similar party (without
Foothill's prior written consent) and are located only at the locations
identified on Schedule 6.12 or otherwise permitted by Section 6.12.

                           (c) Except as set forth on Schedule 5.8, no capital
stock (or any securities, instruments, warrants, options, purchase rights,
conversion or exchange rights, calls, commitments or claims of any character
convertible into or exercisable for capital stock) of any direct or indirect
Subsidiary of Borrower is subject to the issuance of any security, instrument,
warrant, option, purchase right, conversion or exchange right, call, commitment
or claim of any right, title, or interest therein or thereto.

                           (d) On the Closing Date, after giving effect to the
transactions contemplated hereunder to occur on the Closing Date, (i) the
authorized Common Stock will consist of the types and number of shares of
capital stock set forth on Schedule 5.8 hereto and (ii) except for any Warrants

market value or equity value of Borrower.


                  5.9      DUE AUTHORIZATION; NO CONFLICT.

                           (a) The execution, delivery, and performance by

and will not (i) violate any 


                                      -28-
<PAGE>   35


provision of federal, state, or local law or regulation (including Regulations 
G, T, U, and X of the Federal Reserve Board) applicable to Borrower, the 
Governing Documents of Borrower, or any order, judgment, or decree of any

of any Lien of any nature whatsoever upon any properties or assets of 
Borrower, other than Permitted Liens, or (iv) require any approval

                           (c) Other than the filing of appropriate financing
statements, and filings with the United States Copyright Office and the United
States Patent and Trademark Office, the execution, delivery, and performance by
Borrower of this Agreement and the Loan Documents to which Borrower is a party
do not and will not require any registration with, consent, or approval of, or
notice to, or other action with or by, any federal, state, foreign, or other
Governmental Authority or other Person.

                           (d) This Agreement and the Loan Documents to which
Borrower is a party, and all other documents contemplated hereby and thereby,
when executed and delivered by Borrower will be the legally valid and binding
obligations of Borrower, enforceable against Borrower in accordance with their
respective terms, except as enforcement may be limited by equitable principles

relating to or limiting creditors' rights generally.

                           (e) The Liens granted by Borrower to Foothill in and
to its properties and assets pursuant to this Agreement and the other Loan
Documents are validly created, perfected, and first priority Liens, subject only
to Permitted Liens.

                  5.10 LITIGATION. There are no actions or proceedings pending
by or against Borrower before any court or administrative agency and Borrower
does not have knowledge or belief of any pending, threatened, or imminent
litigation, governmental investigations, or claims, complaints, actions, or
prosecutions involving Borrower or any guarantor of the Obligations, except for:
(a) ongoing collection matters in which Borrower is the plaintiff; (b) matters
disclosed on Schedule 5.10; and (c) matters arising after the date hereof that,
if decided adversely to Borrower, would not have a Material Adverse Change.

                  5.11 NO MATERIAL ADVERSE CHANGE. All financial statements
relating to Borrower or any guarantor of the Obligations that have been
delivered by Borrower to Foothill have been prepared in accordance with GAAP
(except, in the case of unaudited financial statements, for the lack of
footnotes and being subject to year-end audit adjustments) and fairly present
Borrower's (or such guarantor's, as applicable) financial condition as of the
date thereof and Borrower's results of operations for the period then ended.
There has not been a Material Adverse Change with respect to Borrower (or such
guarantor, as applicable) since the date of the latest financial statements
submitted to Foothill on or before the Closing Date.

                  5.12 SOLVENCY. Borrower is Solvent. No transfer of property is
being made by Borrower and no obligation is being incurred by Borrower in
connection with the transactions 



                                      -29-
<PAGE>   36

contemplated by this Agreement or the other Loan Documents with the intent to 
hinder, delay, or defraud either present or future creditors of Borrower.

                  5.13 EMPLOYEE BENEFITS. None of Borrower, any of its
Subsidiaries, or any of their ERISA Affiliates maintains or contributes to any
Benefit Plan, other than those listed on Schedule 5.13. Borrower, each of its
Subsidiaries and each ERISA Affiliate have satisfied the minimum funding
standards of ERISA and the IRC with respect to each Benefit Plan to which it is
obligated to contribute. No ERISA Event has occurred nor has any other event
occurred that may result in an ERISA Event that reasonably could be expected to
result in a Material Adverse Change. None of Borrower or its Subsidiaries, any
ERISA Affiliate, or any fiduciary of any Plan is subject to any direct or
indirect liability with respect to any Plan under any applicable law, treaty,
rule, regulation, or agreement. None of Borrower or its Subsidiaries or any
ERISA Affiliate is required to provide security to any Plan under Section
401(a)(29) of the IRC.

                  5.14 ENVIRONMENTAL CONDITION. None of Borrower's properties or
assets has ever been used by Borrower or, to the best of Borrower's knowledge,
by previous owners or operators in the disposal of, or to produce, store,
handle, treat, release, or transport, any Hazardous Materials. None of
Borrower's properties or assets has ever been designated or identified in any
manner pursuant to any environmental protection statute as a Hazardous Materials
disposal site, or a candidate for closure pursuant to any environmental
protection statute. No Lien arising under any environmental protection statute
has attached to any revenues or to any real or personal property owned or
operated by Borrower. Borrower has not received a summons, citation, notice, or
directive from the Environmental Protection Agency or any other federal or state
governmental agency concerning any action or omission by Borrower resulting in
the releasing or disposing of Hazardous Materials into the environment.

                  5.15 INTELLECTUAL PROPERTY. Borrower owns or possesses
adequate licenses or other rights to use all patents, patent applications,
trademark, trademark applications, servicemarks, servicemark applications, trade
names, copyrights, source code, mask-works, trade secrets and know-how
(collectively, the "Intellectual Property") that are necessary for the operation
of Borrower's business as currently conducted, which such Intellectual Property
is described on Schedule 5.15. No claim is pending or threatened in writing to
the effect that Borrower infringes upon, or conflicts with, the asserted rights
of any other Person under any Intellectual Property, and there is no basis for
any such claim (whether pending or threatened, and which, if determined
adversely to Borrower, reasonably could be expected to result in a Material
Adverse Change). No claim is pending or threatened in writing to the effect that
any such Intellectual Property owned or licensed by any Obligor or in which any
Obligor otherwise has the right to use is invalid or unenforceable by such
Obligor, and there is no basis for any such claim (whether or not pending or
threatened, and which, if determined adversely to any Obligor, reasonably could
be expected to result in a Material Adverse Change).

                  5.16 YEAR 2000 COMPLIANCE. Any reprogramming required to
permit the proper functioning, in and following the year 2000, of (A) Borrower's
computer systems and (B) equipment containing embedded microchips (including
systems and equipment supplied by others or with which Borrower's systems
interface) and the testing of all such systems and equipment, as so
reprogrammed, will be completed by March 31, 1999. The cost to Borrower of such

                                      -30-
<PAGE>   37

reprogramming and testing and of the reasonably foreseeable consequences of year
2000 to Borrower (including, without limitation, reprogramming errors and the
failure of others' systems or equipment) will not result in an Event of Default
or a Material Adverse Change. Except for such of the reprogramming referred to
in the preceding sentences of this Section 5.16 as may be necessary, the
computer and management information systems of Borrower are and, with ordinary
course upgrading and maintenance, will continue to be, sufficient to permit
Borrower to conduct its business without a Material Adverse Change.

         6.       AFFIRMATIVE COVENANTS.

                  Borrower covenants and agrees that, so long as any credit
hereunder shall be available and until full and final payment of the
Obligations, and unless Foothill shall otherwise consent in writing, Borrower
shall do all of the following:

                  6.1 ACCOUNTING SYSTEM. Maintain a standard and modern system
of accounting that enables Borrower to produce financial statements in
accordance with GAAP, and maintain records pertaining to the Collateral that
contain information as from time to time may be requested by Foothill. Borrower
also shall keep a modern inventory reporting system that shows all additions,
sales, claims, returns, and allowances with respect to the Inventory.

                  6.2 COLLATERAL REPORTING. Provide Foothill with the following
documents at the following times in form satisfactory to Foothill: (a) on each
Business Day, a sales journal, collection journal, and credit register since the
last such schedule and a calculation of the Borrowing Base as of such date, (b)
on a monthly basis and, in any event, by no later than the 20th day of each
month during the term of this Agreement, (i) a detailed calculation of the
Borrowing Base, and (ii) a detailed aging, by total, of the Accounts, together
with a reconciliation to the detailed calculation of the Borrowing Base
previously provided to Foothill, (c) on a monthly basis and, in any event, by no
later than the 20th day of each month during the term of this Agreement, a
summary aging, by vendor, of Borrower's accounts payable and any book overdraft,
including a summary of amounts owing by IBM Credit Corporation, (d) at the
request of Foothill, Inventory reports specifying Borrower's cost and the
wholesale market value of its Inventory by category, with additional detail
showing additions to and deletions from the Inventory, (e) at the request of
Foothill, notice of all returns, disputes, or claims, (f) upon request, copies
of invoices in connection with the Accounts, customer statements, credit memos,
remittance advices and reports, deposit slips, shipping and delivery documents
in connection with the Accounts and for Inventory and Equipment acquired by
Borrower, purchase orders and invoices, (g) at the request of Foothill, a
detailed list of Borrower's customers, (h) on a monthly basis, a calculation of
the Dilution for the prior month, (i) at the request of Foothill, copies of the
monthly deferred revenue/maintenance schedules and (j) such other reports as to
the Collateral or the financial condition of Borrower as Foothill may request
from time to time. Original sales invoices evidencing daily sales shall be
mailed by Borrower to each Account Debtor and, at Foothill's direction at any
time that an Event of Default has occurred and is continuing, the invoices shall
indicate on their face that the Account has been assigned to Foothill and that
all payments are to be made directly to Foothill.

                                      -31-

                  6.3 FINANCIAL STATEMENTS, REPORTS, CERTIFICATES. Deliver to
Foothill: (a) as soon as available, but in any event within 30 days after the
end of each month during each of Borrower's fiscal years, a company prepared
balance sheet, income statement, and statement of cash flow covering Borrower's
operations during such period; and (b) as soon as available, but in any event
within 90 days after the end of each of Borrower's fiscal years, financial
statements of Borrower for each such fiscal year, audited by independent
certified public accountants reasonably acceptable to Foothill and certified,
without any qualifications, by such accountants to have been prepared in
accordance with GAAP, together with a certificate of such accountants addressed
to Foothill stating that such accountants do not have knowledge of the existence
of any Default or Event of Default. Such audited financial statements shall
include a balance sheet, profit and loss statement, and statement of cash flow
and, if prepared, such accountants' letter to management. If Borrower is a
parent company of one or more Subsidiaries, or Affiliates, or is a Subsidiary or
Affiliate of another company, then, in addition to the financial statements
referred to above, Borrower agrees to deliver financial statements prepared on a
consolidating basis so as to present Borrower and each such related entity
separately, and on a consolidated basis.

                           Together with the above, Borrower also shall deliver
to Foothill Borrower's Form 10-Q Quarterly Reports, Form 10-K Annual Reports,
and Form 8-K Current Reports, and any other filings made by Borrower with the
Securities and Exchange Commission, if any, as soon as the same are filed, or
any other information that is provided by Borrower to its shareholders, and any
other report reasonably requested by Foothill relating to the financial
condition of Borrower.

                           Each month, together with the financial statements
provided pursuant to Section 6.3(a), Borrower shall deliver to Foothill a
certificate signed by its chief financial officer to the effect that: (i) all
financial statements delivered or caused to be delivered to Foothill hereunder
have been prepared in accordance with GAAP (except, in the case of unaudited
financial statements, for the lack of footnotes and being subject to year-end
audit adjustments) and fairly present the financial condition of Borrower, (ii)
the representations and warranties of Borrower contained in this Agreement and
the other Loan Documents are true and correct in all material respects on and as
of the date of such certificate, as though made on and as of such date (except
to the extent that such representations and warranties relate solely to an
earlier date), (iii) for each month that also is the date on which a financial
covenant in Section 7.20 is to be tested, a Compliance Certificate demonstrating
in reasonable detail compliance at the end of such period with the applicable
financial covenants contained in Section 7.20, and (iv) on the date of delivery
of such certificate to Foothill there does not exist any condition or event that
constitutes a Default or Event of Default (or, in the case of clauses (i), (ii),
or (iii), to the extent of any non-compliance, describing such non-compliance as
to which he or she may have knowledge and what action Borrower has taken, is
taking, or proposes to take with respect thereto).

                           Borrower shall have issued written instructions to
its independent certified public accountants authorizing them to communicate
with Foothill and to release to Foothill whatever financial information
concerning Borrower that Foothill may request. Borrower hereby irrevocably
authorizes and directs all auditors, accountants, or other financial consultants
to deliver to Foothill, at Borrower's expense, copies of Borrower's financial
statements, papers related thereto, and other accounting records of any nature
in their possession, and to disclose to Foothill any information they may have
regarding Borrower's business affairs and financial conditions.


                                      -32-
<PAGE>   39


                           In addition to the financial statements required to
be delivered as set forth above, not later than 30 days prior to the end of each
fiscal year of Borrower, Borrower shall deliver to Foothill financial
projections (including projected income statements, balance sheets and
statements of cash flow, all projected on a monthly basis for the succeeding
fiscal year and on an annual basis for each fiscal year thereafter until the
termination of this Agreement and in each case prepared on a consolidated and
stand alone basis), in form and substance reasonably satisfactory to Foothill;
all such financial projections shall be reasonable, shall be prepared on a
reasonable basis and in good faith, and shall be based on assumptions believed
by Borrower to be reasonable at the time made and from the best information then
available to Borrower.

                  6.4 TAX RETURNS. Deliver to Foothill copies of each of
Borrower's future federal income tax returns, and any amendments thereto, within
30 days of the filing thereof with the Internal Revenue Service.

                  6.5 GUARANTOR REPORTS. Cause any guarantor of any of the
Obligations to deliver its annual financial statements at the time when Borrower
provides its audited financial statements to Foothill and copies of all federal
income tax returns as soon as the same are available and in any event no later
than 30 days after the same are required to be filed by law.

                  6.6 RETURNS. Cause returns and allowances, if any, as between
Borrower and its Account Debtors to be on the same basis and in accordance with
the usual customary practices of Borrower, as they exist at the time of the
execution and delivery of this Agreement. If, at a time when no Event of Default
has occurred and is continuing, any Account Debtor returns any Inventory to
Borrower, Borrower promptly shall determine the reason for such return and, if
Borrower accepts such return, issue a credit memorandum (with a copy to be sent
to Foothill) in the appropriate amount to such Account Debtor. If, at a time
when an Event of Default has occurred and is continuing, any Account Debtor
returns any Inventory to Borrower, Borrower promptly shall determine the reason
for such return and, if Foothill consents (which consent shall not be
unreasonably withheld), issue a credit memorandum (with a copy to be sent to
Foothill) in the appropriate amount to such Account Debtor.

                  6.7 TITLE TO EQUIPMENT. Upon Foothill's request, Borrower
immediately shall deliver to Foothill, properly endorsed, any and all evidences
of ownership of, certificates of title, or applications for title to any items
of Equipment.

                  6.8 MAINTENANCE OF EQUIPMENT. Maintain the Equipment in good
operating condition and repair (ordinary wear and tear excepted), and make all
necessary replacements thereto so that the value and operating efficiency
thereof shall at all times be maintained and preserved. Other than those items
of Equipment that constitute fixtures on the Closing Date, Borrower shall not
permit any item of Equipment to become a fixture to real estate or an accession
to other property, and such Equipment shall at all times remain personal
property.

                  6.9 TAXES. Cause all assessments and taxes, whether real,
personal, or otherwise, due or payable by, or imposed, levied, or assessed
against Borrower or any of its property to be paid in full, before delinquency
or before the expiration of any extension period, except to the extent that the
validity of such assessment or tax shall be the subject of a Permitted Protest.
Borrower shall make due and timely payment or deposit of all such federal,
state, and local 




                                      -33-
<PAGE>   40

taxes, assessments, or contributions required of it by law, and will 
execute and deliver to Foothill, on demand, appropriate certificates
attesting to the payment thereof or deposit with respect thereto. Borrower will
make timely payment or deposit of all tax payments and withholding taxes
required of it by applicable laws, including those laws concerning F.I.C.A.,
F.U.T.A., state disability, and local, state, and federal income taxes, and
will, upon request, furnish Foothill with proof satisfactory to Foothill
indicating that Borrower has made such payments or deposits.

                  6.10     INSURANCE.

                           (a) At its expense, keep the Collateral insured
against loss or damage by fire, theft, explosion, sprinklers, and all other
hazards and risks, and in such amounts, as are ordinarily insured against by
other owners in similar businesses. Borrower also shall maintain business
interruption, public liability, product liability, and property damage insurance
relating to Borrower's ownership and use of the Collateral, as well as insurance
against larceny, embezzlement, and criminal misappropriation.

                           (b) All such policies of insurance shall be in such
form, with such companies, and in such amounts as may be reasonably satisfactory
to Foothill. All insurance required herein shall be written by companies which
are authorized to do insurance business in the States of Michigan and New York.
All hazard insurance and such other insurance as Foothill shall specify, shall
contain a standard form endorsement satisfactory to Foothill, showing Foothill
as sole loss payee thereof, and shall contain a waiver of warranties. Every
policy of insurance referred to in this Section 6.10 shall contain an agreement
by the insurer that it will not cancel such policy except after 30 days prior
written notice to Foothill and that any loss payable thereunder shall be payable
notwithstanding any act or negligence of Borrower or Foothill which might,
absent such agreement, result in a forfeiture of all or a part of such insurance
payment. Borrower shall deliver to Foothill certified copies of such policies of
insurance and evidence of the payment of all premiums therefor.

                           (c) Original policies or certificates thereof
satisfactory to Foothill evidencing such insurance shall be delivered to
Foothill at least 30 days prior to the expiration of the existing or preceding
policies. Borrower shall give Foothill prompt notice of any loss covered by such
insurance. At any time that an Event of Default has occurred and is continuing,
or if the loss is in excess of $250,000, Foothill shall have the exclusive right
to adjust any such losses payable under any such insurance policies without any
liability to Borrower whatsoever in respect of such adjustments. Any monies
received as payment for any loss under any insurance policy including the
insurance policies mentioned above, shall be paid over to Foothill to be applied
at the option of Foothill either to the prepayment of the Obligations without
premium, in such order or manner as Foothill may elect, or shall be disbursed to
Borrower under stage payment terms satisfactory to Foothill for application to
the cost of repairs, replacements, or restorations. All repairs, replacements,
or restorations shall be effected with reasonable promptness and shall be of a
value at least equal to the value of the items or property destroyed prior to
such damage or destruction. Upon the occurrence of an Event of Default, Foothill
shall have the right to apply all prepaid premiums to the payment of the
Obligations in such order or form as Foothill shall determine.

                                      -34-
<PAGE>   41


                           (d) Borrower shall not take out separate insurance
concurrent in form or contributing in the event of loss with that required to be
maintained under this Section 6.10, unless Foothill is included thereon as named
insured with the loss payable to Foothill under a standard endorsement. Borrower
immediately shall notify Foothill whenever such separate insurance is taken out,
specifying the insurer thereunder and full particulars as to the policies
evidencing the same, and originals of such policies immediately shall be
provided to Foothill.

(i) the terms and conditions of such refinancings, renewals, or extensions do
not materially impair the prospects of repayment of the Obligations by Borrower,
(ii) the net cash proceeds of such refinancings, renewals, or extensions do not
result in an increase in the aggregate principal amount of the Indebtedness so

guarantor, make such payments and do such acts as Foothill considers necessary
or reasonable to protect its security interests in the Collateral. Borrower
agrees to assemble the Collateral if Foothill so requires, and to make the
Collateral available to Foothill as Foothill may designate. Borrower authorizes
Foothill to enter the premises where the Collateral is located, to take and
maintain possession of the Collateral, or any part of it, and to pay, purchase,
contest, or compromise any encumbrance, charge, or Lien that in Foothill's
determination appears to conflict with its security interests and to pay all
expenses incurred in connection therewith. With respect to any of Borrower's
owned or leased premises, Borrower hereby grants Foothill a license to enter
into possession of such premises and to occupy the same, without charge, for up
to 120 days in order to exercise any of Foothill's rights or remedies provided
herein, at law, in equity, or otherwise;

                           (g) Without notice to Borrower (such notice being
expressly waived), and without constituting a retention of any collateral in
satisfaction of an obligation (within the meaning of Section 9-505 of the Code),
set off and apply to the Obligations any and all (i) balances and deposits of
Borrower held by Foothill (including any amounts received in the Lockbox
Accounts), or (ii) indebtedness at any time owing to or for the credit or the
account of Borrower held by Foothill;

                           (h) Hold, as cash collateral, any and all balances
and deposits of Borrower held by Foothill, and any amounts received in the
Lockbox Accounts, to secure the full and final repayment of all of the
Obligations;

                           (i) Ship, reclaim, recover, store, finish, maintain,
repair, prepare for sale, advertise for sale, and sell (in the manner provided
for herein) the Collateral. Foothill is hereby granted a license or other right
to use, without charge, Borrower's labels, patents, copyrights, 



                                      -43-

rights of use of any name, trade secrets, trade names, trademarks, service 
marks, and advertising matter, or any property of a similar nature, as it 
pertains to the Collateral, in completing production of, advertising for sale, 
and selling any Collateral and Borrower's rights under all licenses and all 
franchise agreements shall inure to Foothill's benefit;

                           (j) Sell the Collateral at either a public or private
sale, or both, by way of one or more contracts or transactions, for cash or on
terms, in such manner and at such places (including Borrower's premises) as
Foothill determines is commercially reasonable. It is not necessary that the
Collateral be present at any such sale;

                           (k) Foothill shall give notice of the disposition of
the Collateral as follows:

                                    (1) Foothill shall give Borrower and each 
holder of a security interest in the Collateral who has filed with Foothill a 
written request for notice, a notice in writing of the time and place of 
public sale, or, if the sale is a private sale or some other disposition 
other than a public sale is to be made of the Collateral, then the
time on or after which the private sale or other disposition is to be made;

                                    (2) The notice shall be personally delivered
or mailed, postage prepaid, to Borrower as provided in Section 12, at least 5 
days before the date fixed for the sale, or at least 5 days before the date on 
or after which the private sale or other disposition is to be made; no 
notice needs to be given prior to the disposition of any portion of the 
Collateral that is perishable or threatens to decline speedily in value or 
that is of a type customarily sold on a recognized market.  Notice to 
Persons other than Borrower claiming an interest in the Collateral
shall be sent to such addresses as they have furnished to Foothill;

                                    (3) If the sale is to be a public sale, 
Foothill also shall give notice of the time and place by publishing a notice 
one time at least 5 days before the date of the sale in a newspaper of 
general circulation in the county in which the sale is to be held;

                           (l) Foothill may credit bid and purchase at any
public sale; and

                           (m) Any deficiency that exists after disposition of
the Personal Property Collateral as provided above will be paid immediately by
Borrower. Any excess will be returned, without interest and subject to the
rights of third Persons, by Foothill to Borrower.

                  9.2 REMEDIES CUMULATIVE. Foothill's rights and remedies under
this Agreement, the Loan Documents, and all other agreements shall be
cumulative. Foothill shall have all other rights and remedies not inconsistent
herewith as provided under the Code, by law, or in equity. No exercise by
Foothill of one right or remedy shall be deemed an election, and no waiver by
Foothill of any Event of Default shall be deemed a continuing waiver. No delay
by Foothill shall constitute a waiver, election, or acquiescence by it.



                                      -44-

         10.      TAXES AND EXPENSES.

                  If Borrower fails to pay any monies (whether taxes,
assessments, insurance premiums, or, in the case of leased properties or assets,
rents or other amounts payable under such leases) due to third Persons, or fails
to make any deposits or furnish any required proof of payment or deposit, all as
required under the terms of this Agreement, then, to the extent that Foothill
determines that such failure by Borrower could result in a Material Adverse
Change, in its discretion and without prior notice to Borrower, Foothill may do
any or all of the following: (a) make payment of the same or any part thereof by
charging Borrower's Loan Account therefor; (b) set up such reserves to the
Borrowing Base as Foothill deems necessary to protect Foothill from the exposure
created by such failure, including, without limitation, a $100,000 reserve with
respect to state tax liens as of the Closing Date which such reserve shall be
released or increased in accordance with Section 3.3(c) of this Agreement; or
(c) obtain and maintain insurance policies of the type described in Section
6.10, and take any action with respect to such policies as Foothill deems
prudent. Any such amounts paid by Foothill shall constitute Foothill Expenses.
Any such payments made by Foothill shall not constitute an agreement by Foothill
to make similar payments in the future or a waiver by Foothill of any Event of
Default under this Agreement. Foothill need not inquire as to, or contest the
validity of, any such expense, tax, or Lien and the receipt of the usual
official notice for the payment thereof shall be conclusive evidence that the
same was validly due and owing.

         11.      WAIVERS; INDEMNIFICATION.

                  11.1 DEMAND; PROTEST; ETC. Borrower waives demand, protest,
notice of protest, notice of default or dishonor, notice of payment and
nonpayment, nonpayment at maturity, release, compromise, settlement, extension,
or renewal of accounts, documents, instruments, chattel paper, and guarantees at
any time held by Foothill on which Borrower may in any way be liable.

                  11.2 FOOTHILL'S LIABILITY FOR COLLATERAL. So long as Foothill
complies with its obligations, if any, under Section 9-207 of the Code, Foothill
shall not in any way or manner be liable or responsible for: (a) the safekeeping
of the Collateral; (b) any loss or damage thereto occurring or arising in any
manner or fashion from any cause; (c) any diminution in the value thereof; or
(d) any act or default of any carrier, warehouseman, bailee, forwarding agency,
or other Person. All risk of loss, damage, or destruction of the Collateral
shall be borne by Borrower.

                  11.3 INDEMNIFICATION. Borrower shall pay, indemnify, defend,
and hold Foothill, each Participant, and each of their respective officers,
directors, employees, counsel, agents, and attorneys-in-fact (each, an
"Indemnified Person") harmless (to the fullest extent permitted by law) from and
against any and all claims, demands, suits, actions, investigations,
proceedings, and damages, and all reasonable attorneys fees and disbursements
and other costs and expenses actually incurred in connection therewith (as and
when they are incurred and irrespective of whether suit is brought), at any time
asserted against, imposed upon, or incurred by any of them in connection with or
as a result of or related to the execution, delivery, enforcement, performance,
and administration of this Agreement and any other Loan Documents or the
transactions contemplated herein, and with respect to any investigation,
litigation, or proceeding related to this Agreement, any other Loan Document, or
the use of the proceeds of the credit provided hereunder (irrespective of
whether any 




                                      -45-


<PAGE>   52

Indemnified Person is a party thereto), or any act, omission, event or 
circumstance in any manner related thereto (all the foregoing, collectively,
the "Indemnified Liabilities"). Borrower shall have no obligation to any
Indemnified Person under this Section 11.3 with respect to any Indemnified
Liability that a court of competent jurisdiction finally determines to have
resulted from the gross negligence or willful misconduct of such Indemnified
Person. This provision shall survive the termination of this Agreement and the
repayment of the Obligations.

         12.      ISSUANCE OF EQUITY INTERESTS TO FOOTHILL

                  12.1 AUTHORIZATION AND ISSUANCE OF WARRANTS. Borrower has
authorized (a) the issuance of a common stock purchase warrant in the form of
Exhibit W hereto (such warrant, together with the rights to purchase Common
Stock provided thereby and all warrants covering such stock issued upon
transfer, division or combination of, or in substitution for, any thereof, being
herein called the "Warrants") for issuance to Foothill pursuant to this
Agreement, and (b) the issuance of such number of shares of Common Stock as
shall be necessary to permit Borrower to comply with its obligations to issue
Common Stock pursuant to the Warrants, which shall initially be an amount equal
to 50,000 of the issued and outstanding shares of Common Stock as of such date
on a fully diluted basis. It is understood and agreed that the Warrants contain
provisions affecting the number of shares of Common Stock that may be acquired,
which provisions are set forth in the Warrants. Such Warrants will have an
initial exercise price equal to an amount not greater than (i) $2.28 per share,
and will cease to be exercisable on a date that is the fifth anniversary of the
Effective Date.

                  12.2     SECURITIES ACT MATTERS.  (a)  Foothill warrants to 
Borrower that:

                           (i) Foothill is acquiring the Warrants hereunder and
         will acquire the Common Stock into which the Warrants are exercisable,
         for investment purposes, for its own account, without a view to the
         distribution thereof, all without prejudice, however, to the right of
         Foothill at any time, in accordance with this Agreement, lawfully to
         sell or otherwise to dispose of all or any part of the Warrants or
         Warrant Stock held by it.

                           (ii) Foothill is an "accredited investor" within the
         meaning of Regulation D under the Securities Act.

                  (b)      Borrower represents and warrants to Foothill that:

                           (i) Assuming the truth and accuracy of Foothill's
         representations and warranties contained in the preceding paragraph,
         the issuance of the Warrants to Foothill hereunder and the issuance of
         shares of Common Stock to Foothill pursuant to the Warrants are exempt
         from the registration and prospectus delivery requirements of the
         Securities Act.

                           (ii) All stock and securities of Borrower heretofore
         issued and sold by Borrower were, and all securities of Borrower issued
         and sold by Borrower on and after the date hereof are or will be issued
         and sold in accordance with, or are or will be exempt from, the
         registration and prospectus delivery requirements of the Securities
         Act.



                                      -46-
<PAGE>   53

                           (iii) Borrower agrees that neither it nor any Person
         acting on its behalf has offered or will offer the Warrants or Warrant
         Stock or any part thereof or any similar securities for issue or sale
         to, or has solicited or will solicit any offer to acquire any of the
         same from, any Person so as to bring the issuance and sale of the
         Warrants or Warrant Stock hereunder within the provisions of the
         registration and prospectus delivery requirements of the Securities
         Act.

                  12.3 CERTAIN TAXES. Borrower shall pay all taxes (other than
Federal, state or local income taxes) which may be payable in connection with
the execution and delivery of this Agreement or the issuance of the Warrants or
Warrant Stock hereunder or in connection with any modification of this Agreement
or the Warrants and shall hold Foothill harmless without limitation as to time
against any and all liabilities with respect to all such taxes. The obligations
of Borrower under this Section 12.3 shall survive any redemption, repurchase or
acquisition of Warrants or Warrant Stock by Borrower, any termination of this
Agreement, and any cancellation or termination of the Warrants.

                  12.4 CANCELLATION AND ISSUANCE. If Foothill assigns or
otherwise transfers all or any of its interests in the Advances (including by
selling participations therein) to any Person, Foothill may request (upon 10
days' prior notice to Borrower) that (a) a number of Warrants held by Foothill
be canceled on the date of such assignment and transfer and (b) a like number of
Warrants be issued by Borrower to the Person to whom such interests in the
Advances are being assigned or otherwise transferred.
Upon the date specified in such request:

                           (i) Borrower shall issue, and Foothill shall
         surrender (or cause to be surrendered) for cancellation, such number of
         Warrants as aforesaid, provided that such issuance shall not violate
         the Securities Act or any applicable state securities laws;

                           (ii) Borrower will deliver to each Person that
         receives a certificate for Warrants a favorable legal opinion from
         counsel to Borrower acceptable to such Person, covering the matters set
         forth in the opinion of counsel to Borrower delivered to Foothill on
         the Closing Date (to the extent relating to the Warrants);

                           (iii) each Person that receives a certificate for
         Warrants will deliver a certificate to Borrower affirming the
         representations and warranties contained in Section 12.2 hereof as of
         such date; and

                           (iv) Borrower will deliver a certificate to each
         Person that receives a certificate for Warrants affirming the
         representations and warranties contained in Section 12.2 hereof as of
         such date.

         13.      NOTICES.

                  Unless otherwise provided in this Agreement, all notices or
demands by any party relating to this Agreement or any other Loan Document shall

WITH THE LAWS OF THE STATE OF NEW YORK. THE PARTIES AGREE THAT ALL ACTIONS 
OR PROCEEDINGS ARISING IN CONNECTION WITH THIS AGREEMENT AND THE OTHER LOAN 
DOCUMENTS SHALL BE TRIED AND LITIGATED ONLY IN THE STATE AND FEDERAL COURTS 
LOCATED IN THE COUNTY OF NEW YORK, STATE OF NEW YORK OR, AT THE SOLE 
OPTION OF FOOTHILL, IN ANY OTHER COURT IN WHICH FOOTHILL SHALL
INITIATE LEGAL OR EQUITABLE PROCEEDINGS AND WHICH HAS SUBJECT MATTER
JURISDICTION OVER THE MATTER IN CONTROVERSY. EACH OF BORROWER AND FOOTHILL
WAIVES, TO THE EXTENT PERMITTED UNDER APPLICABLE LAW, ANY RIGHT EACH MAY HAVE TO
ASSERT THE DOCTRINE OF FORUM NON CONVENIENS OR TO OBJECT TO VENUE TO THE EXTENT
ANY PROCEEDING IS BROUGHT IN ACCORDANCE WITH THIS SECTION 14. BORROWER AND
FOOTHILL HEREBY WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR
CAUSE OF ACTION BASED UPON OR ARISING OUT OF ANY OF THE LOAN DOCUMENTS OR ANY OF
THE TRANSACTIONS CONTEMPLATED THEREIN, INCLUDING CONTRACT CLAIMS, TORT CLAIMS,
BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW OR STATUTORY CLAIMS. EACH OF

         15.      DESTRUCTION OF BORROWER'S DOCUMENTS.

                  All documents, schedules, invoices, agings, or other papers
delivered to Foothill may be destroyed or otherwise disposed of by Foothill four
(4) months after they are delivered to or received by Foothill, unless Borrower
requests, in writing, the return of said documents, schedules, or other papers
and makes arrangements, at Borrower's expense, for their return.

         16.      GENERAL PROVISIONS.

                  16.1 EFFECTIVENESS. This Agreement shall be binding and deemed
effective when executed by Borrower and Foothill.

                  16.2 SUCCESSORS AND ASSIGNS. This Agreement shall bind and
inure to the benefit of the respective successors and assigns of each of the
parties; provided, however, that Borrower may not assign this Agreement or any
rights or duties hereunder without Foothill's prior written consent and any
prohibited assignment shall be absolutely void. No consent to an assignment by
Foothill shall release Borrower from its Obligations. Foothill may assign this
Agreement and all of its rights and duties hereunder with Borrower's consent,
which consent shall not be unreasonably withheld or delayed; provided, however,
that the consent of Borrower shall not be required for any assignment by
Foothill (a) to an Affiliate of Foothill, (b) in connection with a bulk sale of
all or a material portion of the assets of Foothill and/or (c) at any time when
an Event of Default shall have occurred and be continuing. Foothill reserves the
right to sell, assign, transfer, negotiate, or grant participations in all or
any part of, or any interest in Foothill's rights and benefits 



                                      -49-
<PAGE>   56


hereunder. In connection with any such assignment or participation, Foothill 
may disclose all documents and information which Foothill now or hereafter may 
have relating to Borrower or Borrower's business. To the extent that Foothill 
assigns its rights and obligations hereunder to a third Person, Foothill 
thereafter shall be released from such assigned obligations to Borrower and 
such assignment shall effect a novation between Borrower and such third Person.

                  16.3 SECTION HEADINGS. Headings and numbers have been set
forth herein for convenience only. Unless the contrary is compelled by the
context, everything contained in each section applies equally to this entire
Agreement.

                  16.4 INTERPRETATION. Neither this Agreement nor any
uncertainty or ambiguity herein shall be construed or resolved against Foothill
or Borrower, whether under any rule of construction or otherwise. On the
contrary, this Agreement has been reviewed by all parties and shall be construed
and interpreted according to the ordinary meaning of the words used so as to
fairly accomplish the purposes and intentions of all parties hereto.

                  16.5 SEVERABILITY OF PROVISIONS. Each provision of this
Agreement shall be severable from every other provision of this Agreement for
the purpose of determining the legal enforceability of any specific provision.

                  16.6 AMENDMENTS IN WRITING.  This Agreement can only be 
amended by a writing signed by both Foothill and Borrower.

                  16.7 COUNTERPARTS; TELEFACSIMILE EXECUTION. This Agreement may
be executed in any number of counterparts and by different parties on separate
counterparts, each of which, when executed and delivered, shall be deemed to be
an original, and all of which, when taken together, shall constitute but one and
the same Agreement. Delivery of an executed counterpart of this Agreement by
telefacsimile shall be equally as effective as delivery of an original executed
counterpart of this Agreement. Any party delivering an executed counterpart of
this Agreement by telefacsimile also shall deliver an original executed
counterpart of this Agreement but the failure to deliver an original executed
counterpart shall not affect the validity, enforceability, and binding effect of
this Agreement.

                  16.8 REVIVAL AND REINSTATEMENT OF OBLIGATIONS. If the
incurrence or payment of the Obligations by Borrower or any guarantor of the
Obligations or the transfer by either or both of such parties to Foothill of any
property of either or both of such parties should for any reason subsequently be
declared to be void or voidable under any state or federal law relating to
creditors' rights, including provisions of the Bankruptcy Code relating to
fraudulent conveyances, preferences, and other voidable or recoverable payments
of money or transfers of property (collectively, a "Voidable Transfer"), and if
Foothill is required to repay or restore, in whole or in part, any such Voidable
Transfer, or elects to do so upon the reasonable advice of its counsel, then, as
to any such Voidable Transfer, or the amount thereof that Foothill is required
or elects to repay or restore, and as to all reasonable costs, expenses, and
attorneys fees of Foothill related thereto, the liability of Borrower or such
guarantor automatically shall be revived, reinstated, and restored and shall
exist as though such Voidable Transfer had never been made.
