<PAGE>   12
       Whenever Borrower desires an Advance, Borrower will notify Bank by
facsimile transmission or telephone no later than 3:00 p.m. California time, on
the Business Day that the Advance is to be made. Each such notification shall be
promptly confirmed by a Payment/Advance Form in substantially the form of
Exhibit B hereto. Bank is authorized to make Advances under this Agreement,
based upon instructions received from a Responsible Officer, or without
instructions if in Bank's discretion such Advances are necessary to meet
Obligations which have become due and remain unpaid. Bank shall be entitled to
rely on any telephonic notice given by a person whose Bank reasonably believes
to be a Responsible Officer, and Borrower shall indemnify and hold Bank harmless
for any damages or loss suffered by Bank as a result of such reliance. Bank will
credit the amount of Advances made under this Section 2.1 to Borrower's deposit
account.

       The Revolving Facility shall terminate on the Maturity Date, at which
time All Advances under this Section 2.1 and other amounts due under this
Agreement shall be immediately due and payable.

              2.1.1 Letters of Credit.

                    (a) Subject to the terms and conditions of this Agreement,
Bank agrees to issue or cause to be issued letters of credit for the account of
Borrower in an aggregate face amount not to exceed (i) the lesser of the
Committed Line or the Borrowing Base minus (ii) the then outstanding principal
balance of the Advances provided that the face amount of outstanding Letters of
Credit (including drawn but unreimbursed Letters of Credit) shall not in any
case exceed Four Million Dollars ($4,000,000). Each such letter of credit shall
have an expiry date no later than the Maturity Date. All such letters of credit
shall be, in form and substance, acceptable to Bank in its sole discretion and
shall be subject to the terms and conditions of Bank's form of application and
letter of credit agreement. All amounts actually paid by Bank in respect of a
letter of credit shall, when paid, constitute an Advance under this Agreement.

                    (b) The Obligation of Borrower to immediately reimburse Bank
for drawings made under Letters of Credit shall be absolute, unconditional and
irrevocable, and shall be performed strictly in accordance with the terms of
this Agreement and such Letters of Credit, under all circumstances whatsoever.
Borrower shall indemnify, defend and hold Bank harmless from any loss, cost,
expense or liability, including, without limitation, reasonable attorneys' fees,
arising out of or in connection with any letters of credit.

              2.1.2 Letter of Credit Reimbursement; Reserve.

                    (a) Borrower may request that Bank issue a letter of credit
payable in a currency other than United States Dollars. If a demand for payment
is made under any such letter of credit, Bank shall treat such demand as an
advance to Borrower of the equivalent of the amount thereof (plus cable charges)
in United States currency at the then prevailing rate of exchange in San
Francisco, California, for sales of that other currency for cable transfer to
the country of which it is the currency.

                    (b) Upon the issuance of any letter of credit payable in a
currency other than United States Dollars, Bank shall create a reserve under the
Committed Line for letters of credit against fluctuations in currency exchange
rates, in an amount equal to twenty percent (20%) of the face amount of such
letter of credit. The amount of such reserve may be amended by Bank from time to
time to account for fluctuations in the exchange rate. The availability of funds
under the Committed Line shall be reduced by the amount of such reserve for so
long as such letter of credit remains outstanding.

       2.2 Overadvances. If, at any time or for any reason, the amount of
Obligations owed by Borrower to Bank pursuant to Section 2.1 of this Agreement
is greater than the lesser of

                                        9




<PAGE>   13
(i) the Committed Line or (ii) the Borrowing Base, Borrower shall immediately
pay to Bank, in cash, the amount of such excess.

              2.3 Interest Rates, Payments, and Calculations.

                    (a) Interest Rate. Except as set forth in Section 2.3(b),
any Advances shall bear interest, on the average Daily Balance, at a rate equal
to Three Quarters of One (0.75) percentage point above the Prime Rate.

                    (b) Default Rate. At Bank's option and with notice to
Borrower all Obligations shall bear interest, from and after the occurrence and
during the continuance of an Event of Default, at a rate equal to five (5)
percentage points above the interest rate applicable immediately prior to the
occurrence of the Event of Default.

                    (c) Payments. Interest hereunder shall be due and payable on
the last calendar day of each month during the term hereof. Bank shall, at its
option, with notice to Borrower, charge such interest, all Bank Expenses, and
all Periodic Payments against any of Borrower's deposit accounts, or against the
Committed Line, in which case those amounts shall thereafter accrue interest at
the rate then applicable hereunder. Any interest not paid when due shall be
compounded by becoming a part of the Obligations, and such interest shall
thereafter accrue interest at the rate then applicable hereunder.

                    (d) Computation. In the event the Prime Rate is changed from
time to time hereafter, the applicable rate of interest hereunder shall be
increased or decreased effective as of 12:01 a.m. on the day the Prime Rate is
changed, by an amount equal to such change in the Prime Rate. All interest
chargeable under the Loan Documents shall be computed on the basis of a three
hundred sixty (360) day year for the actual number of days elapsed.

              2.4 Crediting Payments. So long as no Event of Default has
occurred and is continuing, Bank shall credit a wire transfer of funds, check or
other item of payment to such deposit account or Obligation as Borrower
specifies. After the occurrence and during the continuance of an Event of
Default, the receipt by Bank of any wire transfer of funds, check, or other item
of payment shall be immediately applied to conditionally reduce Obligations, but
shall not be considered a payment on account unless such payment is of
immediately available federal funds or unless and until such check or other item
of payment is honored when presented for payment. Notwithstanding anything to
the contrary contained herein, any wire transfer or payment received by Bank
after 12:00 noon California time shall be deemed to have been received by Bank
as of the opening of business on the immediately following Business Day.
Whenever any payment to Bank under the Loan Documents would otherwise be due
(except by reason of acceleration) on a date that is not a Business Day, such
payment shall instead be due on the next Business Day, and additional fees or
interest, as the case may be, shall accrue and be payable for the period of such
extension.

              2.5 Fees. Borrower shall pay to Bank the following:

                    (a) Facility Fee. A Facility Fee equal to Fifteen Thousand
Dollars ($15,000), which fee shall be fully earned and non-refundable;

                    (b) Financial Examination and Appraisal Fees. Within thirty
(30) days after demand, Bank's reasonable customary fees and out-of-pocket
expenses for Bank's audits of Borrower's Accounts, and for each appraisal of
Collateral and financial analysis and examination of Borrower performed from
time to time by Bank or its agents;

                    (c) Bank Expenses. Upon the date hereof, all Bank Expenses
incurred through the Closing Date, including reasonable attorneys' fees and
expenses, and, after the date hereof,

                                       10




<PAGE>   14
all Bank Expenses, including reasonable attorneys' fees and expenses, within
thirty (30) days of when they become due.

              2.6 Additional Costs. In case any change in any law, regulation,
treaty or official directive or the interpretation or application thereof by any
court or any governmental authority charged with the administration thereof or
the compliance with any guideline or request of any central bank or other
governmental authority (whether or not having the force of law), in each case
after the date of this Agreement:

                    (a) subjects Bank to any tax with respect to payments of
principal or interest or any other amounts payable hereunder by Borrower or
otherwise with respect to the transactions contemplated hereby (except for taxes
on the overall net income of Bank imposed by the United States of America or any
political subdivision thereof);

                    (b) imposes, modifies or deems applicable any deposit
insurance, reserve, special deposit or similar requirement against assets held
by, or deposits in or for the account of, or loans by, Bank; or

                    (c) imposes upon Bank any other condition with respect to
its performance under this Agreement,

and the result of any of the foregoing is to increase the cost to Bank, reduce
the income receivable by Bank or impose any expense upon Bank with respect to
any loans, Bank shall notify Borrower thereof. Borrower agrees to pay to Bank
the amount of such increase in cost, reduction in income or additional expense
as and when such cost, reduction or expense is incurred or determined, upon
presentation by Bank of a statement of the amount and setting forth Bank's
calculation thereof, all in reasonable detail, which statement shall be deemed
true and correct absent manifest error; provided, however, that the Borrower
shall not be liable for any such amount attributable to any period prior to 180
day prior to the date of such certificate.

              2.7 Term. This Agreement shall become effective on the Closing
Date and, subject to Section 12.7, shall continue in full force and effect for a
term ending on the Maturity Date. Notwithstanding the foregoing, Bank shall have
the right to terminate its obligation to make Advances under this Agreement
immediately and without notice upon the occurrence and during the continuance of
an Event of Default. Notwithstanding termination, Bank's Lien on the Collateral
shall remain in effect for so long as any Obligations are outstanding (excluding
Obligations under Sections 2.6 and 12.2 to the extent they remain inchoate at
the time all outstanding payment obligations are paid in full).

       3. CONDITIONS OF LOANS

              3.1 Conditions Precedent to Initial Advance. The obligation of
Bank to make the initial Advance is subject to the condition precedent that Bank
shall have received, in form and substance satisfactory to Bank, the following:

matters, as Bank may reasonably deem necessary or appropriate.

              3.2 Conditions Precedent to all Advances. The obligation of Bank
to make each Advance, including the initial Advance, is further subject to the
following conditions:

such Payment/Advance Form and on the effective date of each Advance as though
made at and as of each such date (except to the extent they relate specifically
to any earlier date, in which case such representations and warranties shall
continue to have been true and accurate as of such date), and no Event of
Default shall have occurred and be continuing, or would result from such
Advance. The making of each Advance shall be deemed to be a representation and
warranty by Borrower on the date of such Advance as to the accuracy of the facts
referred to in this Section 3.2(b).

       4. CREATION OF SECURITY INTEREST

              4.1 Grant of Security Interest. Borrower grants and pledges to
Bank a continuing security interest in all presently existing and hereafter
acquired or arising Collateral in order to secure prompt repayment of any and
all Obligations and in order to secure prompt performance by Borrower of each of
its covenants and duties under the Loan Documents. Except as set forth in the
Schedule, such security interest constitutes a valid, first priority security
interest in the presently existing Collateral, and will constitute a valid,
first priority security interest in Collateral acquired after the date hereof,
in each case, to the extent that a security interest in such Collateral can be
perfected by the filing of a financing statement, in the case of Collateral
consisting of instruments, documents, chattel paper or certificated securities,
to the extent that Bank takes possession of such Collateral.

              4.2 Delivery of Additional Documentation Required. Borrower shall
from time to time execute and deliver to Bank, at the request of Bank, all
Negotiable Collateral, all financing statements and other documents that Bank
may reasonably request, in form satisfactory to Bank, to perfect and continue
perfected Bank's security interests in the Collateral and in order to fully
consummate all of the transactions contemplated under the Loan Documents.

              4.3 Right to Inspect. Subject to Section 12.8, Bank (through any
of its officers, employees, or agents) shall have the right, upon reasonable
prior notice, from time to time during Borrower's usual business hours, to
inspect Borrower's Books and to make copies thereof and to check, test, and
appraise the Collateral in order to verify Borrower's financial condition or the
amount, condition of, or any other matter relating to, the Collateral.

                                       12




<PAGE>   16
       5. REPRESENTATIONS AND WARRANTIES

       Borrower represents and warrants as follows:

              5.1 Due Organization and Qualification. Borrower and each
Subsidiary is a corporation duly existing and in good standing under the laws of
its state of incorporation and qualified and licensed to do business in, and is
in good standing in, any state in which the conduct of its business or its
ownership of property requires that it be so qualified except for states as to
which any failure so to qualify would not have a Material Adverse Effect.

              5.2 Due Authorization; No Conflict. The execution, delivery, and
performance of the Loan Documents are within Borrower's powers, have been duly
authorized, and are not in conflict with nor constitute a breach of any
provision contained in Borrower's Articles of Incorporation or Bylaws, nor will
they constitute an event of default under any material agreement to which
Borrower is a party or by which Borrower is bound. Borrower is not in default
under any agreement to which it is a party or by which it is bound, which
default would reasonably be expected to have a Material Adverse Effect.

              5.3 No Prior Encumbrances. Borrower has good and indefeasible
title to the Collateral, free and clear of Liens, except for Permitted Liens.

              5.4 Bona Fide Eligible Accounts. The Eligible Accounts are bona
fide existing obligations. 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 Insolvency Proceeding of
any account debtor the Accounts of which are included in any Borrowing Base
Certificate as an Eligible Account.

              5.5 Merchantable Inventory. All Inventory is in all material
respects of good and marketable quality, free from all material defects.

              5.6 Name; Location of Chief Executive Office. Except as disclosed
in the Schedule, Borrower has not done business under any name other than that
specified on the signature page hereof. The chief executive office of Borrower
is located at the address indicated in Section 10 hereof.

              5.7 Litigation. Except as set forth in the Schedule, there are no
actions or proceedings pending (or, to Borrower's knowledge, threatened) by or
against Borrower or any Subsidiary before any court or administrative agency in
which an adverse decision could have a Material Adverse Effect or a material
adverse effect on Borrower's interest or Bank's security interest in the
Collateral.

              5.8 No Material Adverse Change in Financial Statements. All
consolidated financial statements related to Borrower and any Subsidiary that
have been delivered by Borrower to Bank fairly present in all material respects
Borrower's consolidated financial condition as of the date thereof and
Borrower's consolidated results of operations for the period then ended. There
has not been a material adverse change in the consolidated financial condition
of Borrower since the date of the most recent of such financial statements
submitted to Bank, or a material impairment of the prospect of repayment of any
portion of the Obligations or a material impairment of the value or priority of
Bank's security interests in the Collateral.

              5.9 Solvency. Borrower is solvent and able to pay its debts
(including trade debts) as they mature. "Solvent" means that the fair saleable
value of Borrower's assets (including goodwill) exceeds the fair value of its
liabilities.

                                       13




<PAGE>   17
              5.10 Regulatory Compliance. Borrower and each Subsidiary has met
the minimum funding requirements of ERISA with respect to any employee benefit
plans subject to ERISA. No event has occurred resulting from Borrower's failure
to comply with ERISA that is reasonably likely to result in Borrower's incurring
any liability that could have a Material Adverse Effect. Borrower is not an
"investment company" or a company "controlled" by an "investment company" within
the meaning of the Investment Company Act of 1940. Borrower is not engaged
principally, or as one of the important activities, in the business of extending
credit for the purpose of purchasing or carrying margin stock (within the
meaning of Regulations G, T and U of the Board of Governors of the Federal
Reserve System). Borrower has complied with all the provisions of the Federal
Fair Labor Standards Act. Borrower has not violated any statutes, laws,
ordinances or rules applicable to it, violation of which could have a Material
Adverse Effect.

              5.11 Environmental Condition. None of Borrower's or any
Subsidiary's properties or assets has ever been used by Borrower or any
Subsidiary 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 waste or hazardous substance other than in accordance
with applicable law; to the best of Borrower's knowledge, 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 waste or
hazardous substance 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 by Borrower or any Subsidiary; and neither Borrower nor any
Subsidiary has received a summons, citation, notice, or directive from the
Environmental Protection Agency or any other federal, state or other
governmental agency concerning any action or omission by Borrower or any
Subsidiary resulting in the releasing, or otherwise disposing of hazardous waste
or hazardous substances into the environment.

              5.12 Taxes. Borrower and each Subsidiary has filed or caused to be
filed all tax returns required to be filed, and has paid, or has made adequate
provision for the payment of, all taxes reflected therein.

              5.13 Subsidiaries. Borrower does not own any stock, partnership
interest or other equity securities of any Person, except for Permitted
Investments.

              5.14 Government Consents. Borrower and each Subsidiary has
obtained all consents, approvals and authorizations of, made all declarations or
filings with, and given all notices to, all governmental authorities that are
necessary for the continued operation of Borrower's business as currently
conducted except where the failure to obtain any such consent, approval or
authorization, to make any such declaration or filing or to give any such notice
would not reasonably be expected to have a Material Adverse Effect.

              5.15 Full Disclosure. No representation, warranty or other
statement made by Borrower in any certificate or written statement furnished to
Bank contains any untrue statement of a material fact or omits to state a
material fact necessary in order to make the statements contained in such
certificates or statements not misleading (it being recognized by Bank that the
projections and forecasts provided by Borrower are not be viewed as facts and
that actual results during the period or periods covered by any such projections
and forecasts may differ from the projected or forecasted results).

       6. AFFIRMATIVE COVENANTS

<PAGE>   18
              6.1 Good Standing. Borrower shall maintain its and each of its
Subsidiaries' corporate existence and good standing in its jurisdiction of
incorporation and maintain qualification in each jurisdiction in which the
failure to so qualify would reasonably be expected to have a Material Adverse
Effect. Borrower shall maintain, and shall cause each of its Subsidiaries to
maintain, to the extent consistent with prudent management of Borrower's
business, in force all licenses, approvals and agreements, the loss of which
could have a Material Adverse Effect.

              6.2 Government Compliance. Borrower shall meet, and shall cause
each Subsidiary to meet, the minimum funding requirements of ERISA with respect
to any employee benefit plans subject to ERISA. Borrower shall comply, and shall
cause each Subsidiary to comply, with all statutes, laws, ordinances and
government rules and regulations to which it is subject, noncompliance with
which would reasonably be expected to have a Material Adverse Effect or a
material adverse effect on the Collateral or the priority of Bank's Lien on the
Collateral.

              6.3 Financial Statements, Reports, Certificates. Borrower shall
deliver to Bank: (a) as soon as available, but in any event within thirty (30)

Subsidiary of One Hundred Thousand Dollars ($100,000) or more; and (e) such
budgets, sales projections, operating plans or other financial information as
Bank may reasonably request from time to time.

       Within twenty (20) days after the last day of each month, Borrower shall
deliver to Bank a Borrowing Base Certificate signed by a Responsible Officer in
substantially the form of Exhibit C hereto, together with aged listings of
accounts receivable and accounts payable.

       Borrower shall deliver to Bank with the monthly financial statements a
Compliance Certificate signed by a Responsible Officer in substantially the form

       Bank shall have a right from time to time hereafter to audit Borrower's
Accounts at Borrower's expense, provided that such audits will be conducted no
more often than every six (6) months unless an Event of Default has occurred and
is continuing.

              6.4 Inventory; Returns. Borrower shall keep all Inventory in good
and marketable condition, free from all material defects. Returns and
allowances, if any, as between Borrower and its account debtors shall 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. Borrower
shall promptly notify Bank of all returns and recoveries and of all disputes and
claims, where the return, recovery, dispute or claim involves more than One
Hundred Thousand Dollars ($100,000).

              6.5 Taxes. Borrower shall make, and shall cause each Subsidiary to
make, due and timely payment or deposit of all material federal, state, and
local taxes, assessments, or contributions required of it by law, and will
execute and deliver to Bank, on demand, appropriate certificates attesting to
the payment or deposit thereof; and Borrower will make, and will cause each
Subsidiary to make, timely payment or deposit of all material tax payments and
withholding taxes required of it by applicable laws, including, but not limited
to, 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 Bank with proof
satisfactory

                                       15




<PAGE>   19
to Bank indicating that Borrower or a Subsidiary has made such payments or
deposits; provided that Borrower or a Subsidiary need not make any payment if
the amount or validity of such payment is contested in good faith by appropriate
proceedings and is reserved against (to the extent required by GAAP) by
Borrower.

              6.6 Insurance.

                    (a) Borrower, at its expense, shall keep the Collateral
insured against loss or damage by fire, theft, explosion, sprinklers, and all
other hazards and risks, and in such amounts, as ordinarily insured against by
other owners in similar businesses conducted in the locations where Borrower's
business is conducted on the date hereof. Borrower shall also maintain insurance
relating to Borrower's ownership and use of the Collateral in amounts and of a
type that are customary to businesses similar to Borrower's.

                    (b) All such policies of insurance shall be in such form,
with such companies, and in such amounts as reasonably satisfactory to Bank. All
such policies of property insurance shall contain a lender's loss payable
endorsement, in a form satisfactory to Bank, showing Bank as an additional loss
payee thereof and all liability insurance policies shall show the Bank as an
additional insured, and shall specify that the insurer must give at least twenty
(20) days notice to Bank before canceling its policy for any reason. Upon Bank's
request, Borrower shall deliver to Bank certified copies of such policies of
insurance and evidence of the payments of all premiums therefor. So long as no
Event of Default has occurred and is continuing, Borrower shall have the option
of applying the proceeds of any casualty policy to the replacement or repair of
destroyed or damaged property; provided, that after the occurrence and during
the continuance of an Event of Default, all proceeds payable under any such
casualty policy shall, at the option of Bank, be payable to Bank for application
to the Obligations.

depository and operating accounts with Bank.

              6.8 Quick Ratio. Borrower shall maintain, as of the last day of
each calendar month, a ratio of Quick Assets to Current Liabilities of at least

Subordinated Debt to Tangible Net Worth plus Subordinated Debt of not more than
1.75 to 1.0.

              6.10 Tangible Net Worth. Borrower shall maintain, as of the last
day of each calendar month, a Tangible Net Worth plus Subordinated Debt of not
less than Five Million, Two Hundred Fifty Thousand Dollars ($5,250,000).

              6.11 Profitability. Borrower shall have a minimum net profit of
One Dollar ($1.00) for each fiscal quarter; provided, however, that Borrower may
sustain losses not exceeding Two Million Seven Hundred Fifty Thousand Dollars
($2,750,000) for the quarter ending September 30, 1996, and losses of not more
than Two Million Five Hundred Thousand Dollars ($2,500,000) for the quarter
ending December 31, 1996.

              6.12 Further Assurances. At any time and from time to time
Borrower shall execute and deliver such further instruments and take such
further action as may reasonably be requested by Bank to effect the purposes of
this Agreement.

       7. NEGATIVE COVENANTS

              Borrower covenants and agrees that, without Bank's prior consent,
which may be granted or withheld in Bank's sole discretion, so long as any
credit hereunder shall be available and until payment in full of the outstanding
Obligations or for so long as Bank may have any commitment to make any Advances,
Borrower will not do any of the following:

              7.1 Dispositions. Convey, sell, lease, transfer or otherwise
dispose of (collectively, a "Transfer"), or permit any of its Subsidiaries to
Transfer, all or any part of its business or property, other than: (i) Transfers
of Inventory in the ordinary course of business; (ii) Transfers of non-exclusive
licenses and similar arrangements for the use of the property of Borrower or its
Subsidiaries; (iii) Transfers of worn-out or obsolete Equipment, (iv) Transfers
which constitute liquidation of Investments permitted under Section 7.7, and (e)
other Transfers not otherwise permitted by this Section 7.1 not exceeding
$100,000 in any fiscal year.

              7.2 Change in Business. Engage in any business, or permit any of
its Subsidiaries to engage in any business, other than the businesses currently
engaged in by Borrower and any business substantially similar or related thereto
(or incidental thereto), or suffer a material change in Borrower's ownership
(other than as a result of the issuance by Borrower of equity securities).
Borrower will not, without thirty (30) days prior written notification to Bank,
relocate its chief executive office.

              7.3 Mergers or Acquisitions. Merge or consolidate, or permit any
of its Subsidiaries to merge or consolidate, with or into any other business
organization, or acquire, or permit any of its Subsidiaries to acquire, all or
substantially all of the capital stock or property of another Person; provided,
however, that this Section 7.3 shall not apply to transactions among Borrower
and its Subsidiaries in which Borrower is the surviving entity or among its
Subsidiaries, provided no Event of Default exists or would result immediately
after giving effect to such transactions.

              7.4 Indebtedness. Create, incur, assume or be or remain liable
with respect to any Indebtedness, or permit any Subsidiary so to do, other than
Permitted Indebtedness.

              7.5 Encumbrances. Create, incur, assume or suffer to exist any
Lien with respect to any of its property, or assign or otherwise convey any

into or permit to exist any material transaction with any Affiliate of Borrower
except for transactions that are in the ordinary course of Borrower's business,
upon fair and reasonable terms that are no less favorable to Borrower than would
be obtained in an arm's length transaction with a nonaffiliated Person.

              7.9 Subordinated Debt. Make any payment in respect of any
Subordinated Debt, or permit any of its Subsidiaries to make any such payment,
except in compliance with the terms of such Subordinated Debt, or amend any

                                       17




<PAGE>   21
              7.10 lnventory. Store the Inventory with a bailee, warehouseman,
or similar party unless Bank has received a pledge of the warehouse receipt
covering such Inventory. Except for Inventory sold in the ordinary course of
business and except for such other locations as Bank may approve in writing,
Borrower shall keep the Inventory only at the location set forth in Section 10
hereof and such other locations of which Borrower gives Bank prior written
notice and as to which Borrower signs and files a financing statement where
needed to perfect Bank's security interest, provided that Borrower may permit up
to three fully integrated systems (including components) at any time to be used
as demonstration units, the locations of which may change without notice to or
consent of Bank.

              7.11 Compliance. Become an "investment company" controlled by an
"investment company," within the meaning of the Investment Company Act of 1940,
or become principally engaged in, or undertake as one of its important
activities, the business of extending credit for the purpose of purchasing or
carrying margin stock, or use the proceeds of any Advance for such purpose. Fail
to meet the minimum funding requirements of ERISA, permit a Reportable Event or
Prohibited Transaction, as defined in ERISA, to occur, fail to comply with the
Federal Fair Labor Standards Act or violate any law or regulation, which
violation could have a Material Adverse Effect or a material adverse effect on
the Collateral or the priority of Bank's Lien on the Collateral, or permit any
of its Subsidiaries to do any of the foregoing.

       8. EVENTS OF DEFAULT

              Any one or more of the following events shall constitute an Event
of Default by Borrower under this Agreement:

              8.1 Payment Default. If Borrower fails to pay the principal of, or
any interest on, any Advances when due and payable; or fails to pay any portion
of any other Obligations not constituting such principal or interest, including
without limitation Bank Expenses, within thirty (30) days of receipt by Borrower
of an invoice for such other Obligations;

              8.2 Covenant Default. If Borrower fails to perform any obligation
under Sections 6.7 6.8, 6.9, 6.10 or 6.11 or violates any of the covenants
contained in Article 7 of this Agreement, or fails or neglects to perform, keep,
or observe any other material term, provision, condition, covenant, or agreement
contained in this Agreement, in any of the Loan Documents, or in any other
present or future agreement between Borrower and Bank and as to any default
under such other term, provision, condition, covenant or agreement that can be
cured, has failed to cure such default within ten (10) days after Borrower
receives notice thereof or any officer of Borrower becomes aware thereof;
provided, however, that if the default cannot by its nature be cured within the
ten (10) day period or cannot after diligent attempts by Borrower be cured
within such ten (10) day period, and such default is likely to be cured within a
reasonable time, then Borrower shall have an additional reasonable period (which
shall not in any case exceed thirty (30) days) to attempt to cure such default,
and within such reasonable time period the failure to have cured such default
shall not be deemed an Event of Default (provided that no Advances will be
required to be made during such cure period);

              8.3 Attachment. If any material portion of Borrower's assets is
attached, seized, subjected to a writ or distress warrant, or is levied upon, or
comes into the possession of any trustee, receiver or person acting in a similar
capacity and such attachment, seizure, writ or distress warrant or levy has not
been removed, discharged or rescinded within thirty (30) days, or if Borrower is
enjoined, restrained, or in any way prevented by court order from continuing to
conduct all or any material part of its business affairs, or if a judgment or
other claim becomes a lien or encumbrance upon any material portion of
Borrower's assets, or if a notice of lien, levy, or assessment is filed of
record with respect to any of Borrower's assets by the United States Government,
or any department, agency, or instrumentality thereof, or by any state, county,
municipal, or governmental agency, and the same is not paid within ten (10) days
after Borrower receives notice thereof, provided that none of the

                                       18




<PAGE>   22
foregoing shall constitute an Event of Default where such action or event is
stayed or an adequate bond has been posted pending a good faith contest by
Borrower (provided that no Advances will be required to be made during such cure
period);

              8.4 Insolvency. If Borrower becomes insolvent, or if an Insolvency
Proceeding is commenced by Borrower, or if an Insolvency Proceeding is commenced
against Borrower and is not dismissed or stayed within ten (10) days (provided
that no Advances will be made prior to the dismissal of such Insolvency
Proceeding);

              8.5 Other Agreements. If there is a default in any agreement to
which Borrower is a party with a third party or parties resulting in a right by
such third party or parties, whether or not exercised, to accelerate the
maturity of any Indebtedness in an amount in excess of One Hundred Thousand
Dollars ($100,000) or that could reasonably be expected to have a Material
Adverse Effect;

              8.6 Subordinated Debt. If Borrower makes any payment on account of
Subordinated Debt, except to the extent such payment is allowed under any
subordination agreement entered into with Bank;

              8.7 Judgments. If a judgment or judgments for the payment of money
in an amount, individually or in the aggregate, of at least Fifty Thousand
Dollars ($50,000) shall be rendered against Borrower and shall remain
unsatisfied and unstayed for a period of twenty (20) days (provided that no
Advances will be made prior to the satisfaction or stay of such judgment); or

              8.8 Misrepresentations. If any material misrepresentation or
material misstatement exists now or hereafter in any warranty or representation
set forth herein or in any certificate delivered to Bank by any Responsible
Officer pursuant to this Agreement or to induce Bank to enter into this
Agreement or any other Loan Document.

       9. BANK'S RIGHTS AND REMEDIES

              9.1 Rights and Remedies. Upon the occurrence and during the
continuance of an Event of Default, Bank may, at its election, without notice of
its election and without demand, do any one or more of the following, all of
which are authorized by Borrower:

                    (a) Declare all Obligations, whether evidenced by this
Agreement, by any of the other Loan Documents, or otherwise, immediately due and
payable (provided that upon the occurrence of an Event of Default described in
Section 8.5 all Obligations shall become immediately due and payable without any
action by Bank);

                    (b) Cease advancing money or extending credit to or for the
benefit of Borrower under this Agreement or under any other agreement between
Borrower and Bank;

                    (c) Demand that Borrower (i) deposit cash with Bank in an
amount equal to the amount of any Letters of Credit remaining undrawn, as
collateral security for the repayment of any future drawings under such Letters
of Credit, and Borrower shall forthwith deposit and pay such amounts, and (ii)
pay in advance all Letters of Credit fees scheduled to be paid or payable over
the remaining term of the Letters of Credit;

                    (d) Settle or adjust disputes and claims directly with
account debtors for amounts, upon terms and in whatever order that Bank
reasonably considers advisable;

                    (e) Without notice to or demand upon Borrower, make such
payments and do such acts as Bank considers necessary or reasonable to protect
its security interest in the Collateral. Borrower agrees to assemble the
Collateral if Bank so requires, and to make the Collateral

                                       19




<PAGE>   23
available to Bank as Bank may designate. Borrower authorizes Bank 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 which in Bank's determination appears to be prior
or superior to its security interest and to pay all expenses incurred in
connection therewith. With respect to any of Borrower's owned premises, Borrower
hereby grants Bank 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
Bank's rights or remedies provided herein, at law, in equity, or otherwise;

                    (f) Without notice to Borrower set off and apply to the
Obligations any and all (i) balances and deposits of Borrower held by Bank, or
(ii) indebtedness at any time owing to or for the credit or the account of
Borrower held by Bank;

                    (g) Ship, reclaim, recover, store, finish, maintain, repair,
prepare for sale, advertise for sale, and sell (in the manner provided for
herein) the Collateral. Bank is hereby granted a license or other right, solely
pursuant to the provisions of this Section 9.1, to use, without charge,
Borrower's labels, patents, copyrights, 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, in
connection with Bank's exercise of its rights under this Section 9.1, Borrower's
rights under all licenses and all franchise agreements shall inure to Bank's
benefit;

                    (h) 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 Bank
determines is commercially reasonable, and apply any proceeds to the Obligations
in whatever manner or order Bank deems appropriate;

                    (i) Bank may credit bid and purchase at any public sale; and

                    (j) Any deficiency that exists after disposition of the
Collateral as provided above will be paid immediately by Borrower.

              9.2 Power of Attorney. Effective only upon the occurrence and
during the continuance of an Event of Default, Borrower hereby irrevocably
appoints Bank (and any of Bank's designated officers, or employees) as
Borrower's true and lawful attorney to: (a) send requests for verification of
Accounts or notify account debtors of Bank's security interest in the Accounts;
(b) endorse Borrower's name on any checks or other forms of payment or security
that may come into Bank's possession; (c) 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; (d) make, settle, and adjust all claims under and decisions
with respect to Borrower's policies of insurance; and (e) settle and adjust
disputes and claims respecting the accounts directly with account debtors, for
amounts and upon terms which Bank determines to be reasonable; provided Bank may
exercise such power of attorney to sign the name of Borrower on any of the
documents described in Section 4.2 regardless of whether an Event of Default has
occurred. The appointment of Bank as Borrower's attorney in fact, and each and
every one of Bank's rights and powers, being coupled with an interest, is
irrevocable until all of the Obligations have been fully repaid and performed
and Bank's obligation to provide advances hereunder is terminated.

              9.3 Accounts Collection. Upon the occurrence and during the
continuation of an Event of Default, Bank may notify any Person owing funds to
Borrower of Bank's security interest in such funds and verify the amount of such
Account. Borrower shall collect all amounts owing to Borrower for Bank, receive
in trust all payments as Bank's trustee, and immediately deliver such payments
to Bank in their original form as received from the account debtor, with proper
endorsements for deposit.

                                       20




<PAGE>   24
              9.4 Bank Expenses. If Borrower fails to pay any amounts or furnish
any required proof of payment due to third persons or entities, as required
under the terms of this Agreement, then Bank may do any or all of the following:
(a) make payment of the same or any part thereof; (b) set up such reserves under
the Revolving Facility as Bank deems necessary to protect Bank from the exposure
created by such failure; or (c) obtain and maintain insurance policies of the
type discussed in Section 6.6 of this Agreement, and take any action with
respect to such policies as Bank deems prudent. Any amounts so paid or deposited
by Bank shall constitute Bank Expenses, shall be immediately due and payable,
and shall bear interest at the then applicable rate hereinabove provided, and
shall be secured by the Collateral. Any payments made by Bank shall not
constitute an agreement by Bank to make similar payments in the future or a
waiver by Bank of any Event of Default under this Agreement.

              9.5 Bank's Liability for Collateral. So long as Bank complies with
its obligations under Section 9207 of the Code, Bank 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
whomsoever. Subject to the foregoing, all risk of loss, damage or destruction of
the Collateral shall be borne by Borrower.

              9.6 Remedies Cumulative. Bank's rights and remedies under this
Agreement, the Loan Documents, and all other agreements shall be cumulative.
Bank shall have all other rights and remedies not inconsistent herewith as
provided under the Code, by law, or in equity. No exercise by Bank of one right
or remedy shall be deemed an election, and no waiver by Bank of any Event of
Default on Borrower's part shall be deemed a continuing waiver. No delay by Bank
shall constitute a waiver, election, or acquiescence by it. No waiver by Bank
shall be effective unless made in a written document signed on behalf of Bank
and then shall be effective only in the specific instance and for the specific
purpose for which it was given.

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

       10. NOTICES

       12. GENERAL PROVISIONS

              12.1 Assignment; Participations.

                    (a) Bank may sell, negotiate or grant participations to
other financial institutions in all or part of the obligations of the Borrower
outstanding under the Loan Documents without notice to or the approval of
Borrower; provided that any such sale, negotiation or participation shall be in
compliance with the applicable federal and state securities laws and the other
requirements of this Section 12.1. Notwithstanding the sale, negotiation or
grant of participations, Bank shall remain solely responsible for the
performance of its obligations under this Agreement, and Borrower shall continue
to deal solely and directly with Bank in connection with this Agreement and the
other Loan Documents.

                    (b) The grant of a participation interest shall be on such
terms as the Bank determines are appropriate, provided only that (1) the holder
of such a participation interest shall not have any of the rights of Bank under
this Agreement except, if the participation agreement so provides, rights to
demand the payment of costs of the type described in Section 2.6, provided that
the aggregate amount that the Borrower shall be required to pay under Section
2.6 with respect to any ratable share of the Committed Line or any Advance
(including amounts paid to participants) shall not exceed the amount that
Borrower would have had to pay if no participation agreements had been entered
into, and (2) the consent of the holder of such a participation interest shall
not be required for amendments or waivers of provisions of the Loan Agreement
other than those which (i) increase the amount of the Committed Line, (ii)
extend the term of this Agreement, (iii) decrease the rate of interest or the
amount of any fee or any other amount payable to Bank under this Agreement, (iv)
reduce the principal amount payable under this Agreement, or (v) extend the date
fixed for the payment of principal or interest or any other amount payable under
this Agreement.

                    (c) The Bank may assign, from time to time, all or any
portion of its pro rata share of the Committed Line to an Affiliate of the Bank
or to any Federal Reserve Bank, or, subject to the prior written approval of
Borrower (which approval will not be unreasonably withheld), to any other
financial institution; provided, that with respect to an assignment that is
subject to the prior approval of Borrower (i) the amount of the Committed Line
being assigned pursuant to each such assignment shall in no event be less than
$1,000,000, and (ii) the parties to each such assignment shall execute and
deliver to Borrower an assignment agreement in a form reasonably acceptable to
each. Upon such execution and delivery, from and after the effective date
specified in such

                                       22




<PAGE>   26
assignment agreement (x) the assignee thereunder shall be a party hereto and, to
the extent that rights and obligations hereunder have been assigned to it
pursuant to such assignment agreement, have the rights and obligations of Bank
hereunder and (y) Bank shall, to the extent that rights and obligations
hereunder have been assigned by it pursuant to such assignment agreement,
relinquish its rights and be released from its obligations under this Agreement
(other than pursuant to this Section 12.1(d)), and, in the case of an assignment
agreement covering all or the remaining portion of Bank's rights and obligations
under this Agreement, Bank shall cease to be a party hereto. In the event of an
assignment hereunder, the parties agree to amend this Agreement to the extent
necessary to reflect the mechanical changes which are necessary to document such
assignment and which are standard for a multi-bank credit facility. Each party
shall bear its own expenses (including, without limitation, attorneys' fees and
costs) with respect to such an amendment.

              12.2 Indemnification. Borrower shall defend, indemnify and hold
harmless Bank and its officers, employees, and agents against: (a) all
obligations, demands, claims, and liabilities claimed or asserted by any other
party in connection with the transactions contemplated by this Agreement; and
(b) all losses or Bank Expenses in any way suffered, incurred, or paid by Bank
as a result of or in any way arising out of, following, or consequential to
transactions between Bank and Borrower whether under this Agreement, or
otherwise (including without limitation reasonable attorneys fees and expenses),
except for losses caused by Bank's gross negligence or willful misconduct.

              12.3 Time of Essence. Time is of the essence for the performance
of all obligations set forth in this Agreement.

              12.4 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.

              12.5 Amendments in Writing, Integration. This Agreement cannot be
amended or terminated orally. All prior agreements, understandings,
representations, warranties, and negotiations between the parties hereto with
respect to the subject matter of this Agreement, if any, are merged into this
Agreement and the Loan Documents.

              12.6 Counterparts. 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.

              12.7 Survival. All covenants, representations and warranties made
in this Agreement shall continue in full force and effect so long as any
Obligations remain outstanding (excluding Obligations under Sections 2.6 and
12.2 to the extent they remain inchoate at the time all outstanding payment
obligations are paid in full). The obligations of Borrower to indemnify Bank
with respect to the expenses, damages, losses, costs and liabilities described
in Section 12.2 shall survive until all applicable statute of limitations
periods with respect to actions that may be brought against Bank have run,
provided that so long as the obligations set forth in the first sentence of this
Section 12.7 have been satisfied, and Bank has no commitment to make any
Advances or to make any other loans to Borrower, Bank shall release all security
interests granted hereunder and redeliver all Collateral held by it in
accordance with applicable law.

              12.8 Confidentiality. In handling any confidential information
Bank shall exercise the same degree of care that it exercises with respect to
its own proprietary information of the same types to maintain the
confidentiality of any non-public information thereby received or received
pursuant to this Agreement except that disclosure of such information may be
made (i) to the subsidiaries or affiliates of Bank in connection with their
present or prospective business relations with


                                       23



<PAGE>   27
Borrower, (ii) to prospective transferees or purchasers of any interest in the
Loans, provided that they have entered into a comparable confidentiality
agreement in favor of Borrower and have delivered a copy to Borrower, (iii) as
required by law, regulations, rule or order, subpoena, judicial order or similar
order, (iv) as may be required in connection with the examination, audit or
similar investigation of Bank and (v) as Bank may determine in connection with
the enforcement of any remedies hereunder. Confidential information hereunder
shall not include information that either: (a) is in the public domain or in the
knowledge or possession of Bank when disclosed to Bank, or becomes part of the
public domain after disclosure to Bank through no fault of Bank; or (b) is
disclosed to Bank by a third party, provided Bank does not have actual knowledge
that such third party is prohibited from disclosing such information.
Notwithstanding any provision of this Agreement to the contrary, neither
Borrower nor any Subsidiaries will be required to disclose, permit the
inspection, examination, copying or making extracts of, or discussions of, any
document, information or other matter in respect to which disclosure to Bank (or
its designated representative) is then prohibited by (a) law, or (b) an
agreement binding upon Borrower or any Subsidiary that was not entered into by
Borrower or such Subsidiary for the primary purpose of concealing information
from Bank. Notwithstanding any provision of this Agreement to the contrary,
prior to the occurrence of an Event of Default, neither Borrower nor any
Subsidiaries will be required to disclose, permit the inspection, examination,
copying or making extracts of, or discussions of, any documents, information or
other matter that constitutes non-financial trade secrets.

       IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed as of the date first above written.
