to be a Responsible Officer or a designee thereof, 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(a) to Borrower's deposit account.

                      (b) Letters of Credit.

                           (i) 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 (each, a "Letter of Credit" and collectively, the "Letters
of Credit") in an aggregate outstanding face amount not to exceed the sum of (a)
the lesser of the availability under the Committed Revolving Line and the
Borrowing Base, plus (b) the principal amount of Certificates constituting
Collateral; provided the undrawn face amount of such Letters of Credit and any
drawn but unreimbursed Letters of Credit shall not in any case exceed Five
Million Dollars ($5,000,000) in the aggregate. All Letters of Credit shall be,
in form and substance, acceptable to Bank in its sole discretion and shall be
subject to the terms of Bank's form of standard application and letter of credit
agreement, including Bank's fee equal to (i) one percent (1%) of the face amount
of each Letter of Credit issued against pledged certificates of deposit, and
(ii) one and one-half percent (1.5%) of the face amount of each Letter of Credit
issued against Eligible Accounts. On any drawn but unreimbursed Letter of
Credit, the unreimbursed amount shall be deemed an Advance under Section 2.1(a).
No Letter of Credit may have an expiration date later than the Revolving
Maturity Date.

                           (ii) Subject to the penultimate sentence of Section
2.1(b)(i), 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, protect, 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, except for expenses caused
by Bank's gross negligence or willful misconduct.

               2.2 Overadvances. If at any time the aggregate amount of the
outstanding Advances plus the undrawn face amount of any outstanding Letters of
Credit, and any drawn but unreimbursed Letters of Credit, other than Letters of
Credit secured by certificates of deposit, exceeds the lesser of the Borrowing
Base or the Committed Revolving Line, 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),
the Advances shall bear interest, on the outstanding daily balance thereof, at a
rate equal to one percent (1.0%) above the Prime Rate.

                      (b) Default Rate. 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
in arrears on the last calendar day of each month during the term hereof. Bank
shall, at its option, charge such interest, all Bank Expenses, and all Periodic
Payments against any of Borrower's deposit accounts or against the Committed
Revolving 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 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.

                                       8

<PAGE>   10
               2.4 Crediting Payments. Prior to the occurrence of an Event of
Default, 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 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 Eastern 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. On the Closing Date, a Facility Fee
equal to Seventy-Five Thousand Dollars ($75,000), which shall be nonrefundable;

                      (b) Bank Expenses. On the Closing Date, all Bank Expenses
incurred through the Closing Date (provided, that Bank's attorneys' fees and
expenses incurred in connection with the preparation and negotiation of the Loan
Documents shall be paid by Bank with the proceeds of the Facility Fee); and
after the Closing Date, all Bank Expenses, including reasonable attorneys' fees
and expenses, as and when they become due. Bank shall provide to Borrower
monthly accountings of all Bank Expenses.

               2.6 Additional Costs. In case after the date hereof 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):

                      (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
the Obligations, 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.

               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 Revolving Maturity Date. Notwithstanding the foregoing, Bank
shall have the right to terminate its obligation to make Credit Extensions 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.

        3. CONDITIONS OF CREDIT EXTENSIONS.

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

                      (a) this Agreement;

                      (b) a certificate of the Secretary of Borrower with
respect to incumbency and resolutions authorizing the execution and delivery of
this Agreement;

                      (c) financing statements (Forms UCC-1);

                      (d) an intellectual property security agreement;

                      (e) affirmations of each unconditional guaranty and
security agreement of each Guarantor;

                      (f) an agreement to provide insurance;

                      (g) a securities account control agreement;

                      (h) payment of the fees then due specified in Section 2.5
hereof;

                      (i) such other documents, and completion of such other
matters, as Bank may reasonably deem necessary or appropriate.

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

                      (a) timely receipt by Bank of the Payment/Advance Form as
provided in Section 2.1; and

                      (b) the representations and warranties contained in
Section 5 shall be true and correct in all material respects on and as of the
date of such Payment/Advance Form and on the effective date of each Credit
Extension as though made at and as of each such date, and no Event of Default
shall have occurred and be continuing, or would exist after giving effect to
such Credit Extension (provided, however, that those representations and
warranties expressly referring to another date shall be true, correct and
complete in all material respects as of such date). The making of each Credit
Extension shall be deemed to be a representation and warranty by Borrower on the
date of such Credit Extension 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 for Permitted Liens,
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. Prior to the
maturity of any Collateral consisting of certificates of deposit held by Bank
pursuant hereto, Borrower and Bank shall agree upon a security or instrument
similar in form, quality and substance to the original Collateral in which the
proceeds of the Collateral can be reinvested on maturity. Upon maturity of the
Collateral in accordance with its terms, or in the event the Collateral
otherwise becomes payable during the term of this Agreement, such maturing
Collateral may be presented for payment, exchange, or otherwise marketed by Bank
on behalf of Borrower and the proceeds therefrom used to purchase the security
or instrument agreed to by Borrower and Bank in accordance with the immediately
preceding sentence. If no agreement has been

                                       10

<PAGE>   12
made, such proceeds shall be placed into an interest bearing account offered by
Bank in which Bank has a first priority security interest until such time as an
agreement as to the security replacing the original Collateral can be reached.
Bank may retain any such successor collateral and the proceeds therefrom as
Collateral in accordance with the terms of this Agreement. Notwithstanding
termination of this Agreement, Bank's Lien on the Collateral shall remain in
effect for so long as any Obligations are outstanding.

               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, the certificates evidencing all of the outstanding
capital stock of each Guarantor (together with stock powers executed in blank),
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. 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 but no more than once a year
(unless an Event of Default has occurred and is continuing), 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.

        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 under the laws of its state or
province of incorporation and qualified and licensed to do business in any
jurisdiction in which failure to be so qualified or licensed could reasonably be
expected to 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 could 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 acceptance by the account debtor, subject only to
usual and customary return rights, or the services giving rise to such Eligible
Accounts have been fully performed. Borrower has not received notice of actual
or imminent Insolvency Proceeding of any account debtor that is included in any
Borrowing Base Certificate as an Eligible Account.

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

               5.6 Intellectual Property Collateral. Borrower is the sole owner
of the Intellectual Property Collateral, except for non-exclusive licenses
granted by Borrower to its customers in the ordinary course of business. Each of
the Patents is valid and enforceable, and no part of the Intellectual Property
Collateral has been judged invalid or unenforceable, in whole or in part, and no
claim has been made that any part of the Intellectual Property Collateral
violates the rights of any third party. The Intellectual Property Security
Agreement sets forth all of the Intellectual Property Collateral that is
material to Borrower's business. Except as set forth in the Schedule, Borrower's
rights as a licensee of intellectual property do not give rise to more than five
percent (5%) of its gross

                                       11

<PAGE>   13
revenue in any given month, including without limitation revenue derived from
the sale, licensing, rendering or disposition of any product or service.

               5.7 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.

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

               5.9 No Material Adverse Change in Financial Statements. All
consolidated financial statements of Borrower and any Subsidiary that are
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.

               5.10 Solvency, Payment of Debts. Borrower is solvent and able to
pay its debts (including trade debts) as they mature.

               5.11 Regulatory Compliance. Borrower and each Subsidiary have 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 T and U of the Board of Governors of the Federal Reserve
System). Borrower has complied in all material respects 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 reasonably
be expected to have a Material Adverse Effect.

               5.12 Environmental Condition. Except as disclosed in the
Schedule, 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.

               5.13 Taxes. Borrower and each Subsidiary have filed or caused to
be filed all tax returns required to be filed, and have paid (unless the same
are being contested in good faith by appropriate proceedings), or have made
adequate provision for the payment of, all taxes reflected therein.

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

               5.15 Government Consents. Borrower and each Subsidiary have
obtained all consents, approvals and authorizations of, made all declarations or
filings with, and given all notices to, all governmental

                                       12

<PAGE>   14
authorities that are necessary for the continued operation of Borrower's
business as currently conducted, the failure to obtain which could reasonably be
expected to have a Material Adverse Effect.

               5.16 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.

        6. AFFIRMATIVE COVENANTS.

               Borrower covenants and agrees that, until payment in full of all
outstanding Obligations, and for so long as Bank may have any commitment to make
a Credit Extension hereunder, Borrower shall do all of the following:

               6.1 Good Standing. Borrower shall maintain its and each of its
Subsidiaries' corporate existence in its jurisdiction of incorporation and
maintain qualification in each jurisdiction in which the failure to so qualify
could reasonably be expected to have a Material Adverse Effect. Borrower shall
maintain, and shall cause each of its Subsidiaries to maintain, in force all
licenses, approvals and agreements, the loss of which could reasonably be
expected to 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 could 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)
days after the end of each calendar month in which a Credit Extension against
Eligible Accounts is outstanding (or, if no such Credit Extension is
outstanding, as a condition precedent to a request for such a Credit Extension),
a company prepared consolidated balance sheet and income statement covering
Borrower's consolidated operations during such period, prepared in accordance
with GAAP, consistently applied, in a form acceptable to Bank and certified by a
Responsible Officer; (b) as soon as available, but in any event within one
hundred twenty (120) days after the end of Borrower's fiscal year, audited
consolidated financial statements of Borrower prepared in accordance with GAAP,
consistently applied, together with an unqualified opinion on such financial
statements of an independent certified public accounting firm reasonably
acceptable to Bank (or a qualified opinion subject only to a "going concern"
qualification or "ability to raise additional equity" qualification or other
similar qualification); (c) copies of all statements, reports and notices sent
or made available generally by Borrower to its security holders or to any
holders of Subordinated Debt and all reports on Forms 10-K and 10-Q filed with
the Securities and Exchange Commission; (d) promptly upon receipt of notice
thereof, a report of any legal actions pending or threatened against Borrower or
any Subsidiary that could reasonably be expected to result in damages or costs
to Borrower or any Subsidiary of Fifty Thousand Dollars ($50,000) or more; and
(e) such budgets, sales projections, operating plans or other financial
information as Bank may reasonably request from time to time generally prepared
by Borrower in the ordinary course of business.

        Within thirty (30) days after the last day of each month in which any
Credit Extension against Eligible Accounts is outstanding (or, if no such Credit
Extension is outstanding, within thirty (30) days after the last day of each
fiscal quarter, and as a condition precedent to a request for such a Credit
Extension), Borrower shall deliver to Bank a Borrowing Base Certificate signed
by a Responsible Officer in substantially the form of Exhibit D 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

                                       13

<PAGE>   15
        Bank shall have a right from time to time hereafter to audit Borrower's
Accounts and appraise Collateral at Borrower's expense, provided that such
audits will be conducted no more often than annually 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 except for Inventory
for which adequate reserves have been made. 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 Fifty Thousand Dollars
($50,000).

               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 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. All proceeds
payable under any such policy shall, at the option of Bank, be payable to Bank
to be applied on account of the Obligations.

               6.7 Principal Depository. Borrower shall maintain with Bank
depository and operating accounts having average balances of not less than

from the Closing Date through the last day of each month of not less than 75% of
the revenue set forth in the forecast dated June 19, 2000 delivered to Bank.

               6.10 Adjusted Net Worth. Borrower shall maintain at all times an
Adjusted Net Worth of at least Ten Million Dollars ($10,000,000), plus 25% of

Debt by the Borrower after the date hereof.

               6.11 Total Liabilities-Tangible Net Worth. Borrower shall
maintain, as of the last day of each calendar month, a ratio of Total

               6.12 Registration of Intellectual Property Rights.

                      (a) Borrower shall register or cause to be registered on
an expedited basis (to the extent not already registered) with the United States
Patent and Trademark Office or the United States Copyright Office, as
applicable: (i) those intellectual property rights listed on Exhibits A, B and C
to the Intellectual Property Security Agreement delivered to Bank by Borrower in
connection with this Agreement, within thirty (30) days of the date of this
Agreement, (ii) all registerable intellectual property rights Borrower has
developed as of the date of this Agreement but heretofore failed to register,
within thirty (30) days of the date of this Agreement, and (iii) those
additional intellectual property rights developed or acquired by Borrower from
time to time in connection with any product, prior to the sale or licensing of
such product to any third party, and prior to Borrower's use of such product
(including without limitation major revisions or additions to the intellectual
property rights listed on such Exhibits A, B and C). Borrower shall give Bank
notice of all such applications or registrations.

                      (b) Borrower shall execute and deliver such additional
instruments and documents from time to time as Bank shall reasonably request to
perfect Bank's security interest in the Intellectual Property Collateral.

                      (c) Borrower shall (i) protect, defend and maintain the
validity and enforceability of the Trademarks, Patents and Copyrights, (ii) use
its best efforts to detect infringements of the Trademarks, Patents and
Copyrights and promptly advise Bank in writing of material infringements
detected and (iii) not allow any material Trademarks, Patents or Copyrights to
be abandoned, forfeited or dedicated to the public without the written consent
of Bank, which shall not be unreasonably withheld.

                      (d) Bank may audit Borrower's Intellectual Property
Collateral to confirm compliance with this Section, provided such audit may not
occur more often than once per year, unless an Event of Default has occurred and
is continuing. Bank shall have the right, but not the obligation, to take, at
Borrower's sole expense, any actions that Borrower is required under this
Section to take but which Borrower fails to take, after fifteen (15) days'
notice to Borrower. Borrower shall reimburse and indemnify Bank for all
reasonable costs and reasonable expenses incurred in the reasonable exercise of
its rights under this Section.

               6.13 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, 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 Credit
Extensions, Borrower will not do any of the following without the prior written
consent of Bank:

               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; or (iii) Transfers of surplus, worn-out or obsolete Equipment; or
(iv) Transfers of property with an aggregate value of $100,000 or less per
fiscal year of Borrower.

               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 its Subsidiaries and any business substantially
similar or related thereto (or incidental thereto). 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

                                       15

<PAGE>   17
acquire, all or substantially all of the capital stock or property of another
Person; provided that a Subsidiary of Borrower may merge with and into Borrower,
so long as Borrower is the surviving entity.

               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
right to receive income, including the sale of any Accounts, or permit any of
its Subsidiaries so to do, except for Permitted Liens.

               7.6 Distributions. Pay any dividends or make any other
distribution or payment on account of or in redemption, retirement or purchase
of any capital stock, except that Borrower may (i) repurchase the stock of
former employees pursuant to stock repurchase agreements, but only so long as an
Event of Default does not exist or would not exist after giving effect to such
repurchase and (ii) make distributions in capital stock of Borrower.

               7.7 Investments. Directly or indirectly acquire or own, or make
any Investment in or to any Person, or permit any of its Subsidiaries so to do,
other than Permitted Investments.

               7.8 Transactions with Affiliates. Directly or indirectly enter
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 non-affiliated 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
provision contained in any documentation relating to the Subordinated Debt
without Bank's prior written consent.

               7.10 Inventory and Equipment. Store the Inventory or the
Equipment with a bailee, warehouseman, or similar party unless Bank has received
a pledge of the warehouse receipt covering such Inventory; provided, however,
that Borrower may deposit software code in escrow for customers in the ordinary
course of business. 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 and Equipment 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 at Bank's request a financing
statement where needed to perfect Bank's security interest.

               7.11 Compliance. Become an "investment company" or be 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 Credit Extension 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 in all material respects with the Federal Fair Labor Standards Act or
violate any law or regulation, which violation could 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, or permit any of its
Subsidiaries to do any of the foregoing.

               7.12 Negative Pledge Agreements. Borrower shall not permit the
inclusion in any contract to which it becomes a party of any provisions that
could or might in any way prevent the creation of a security interest in
Borrower's rights and interests in any Collateral, unless an exception is made
therein for the security interest of Bank.

        8. EVENTS OF DEFAULT.

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

                                       16

<PAGE>   18
               8.1 Payment Default. If Borrower fails to pay, when due, any of
the Obligations;

               8.2 Covenant Default. If Borrower fails to perform any obligation
under Article 6 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 Credit Extensions will be required to be made
during such cure period);

               8.3 Material Adverse Change. If there occurs a material adverse
change in Borrower's business or financial condition, or if there is 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;

               8.4 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 thirty (30)
days after Borrower receives notice thereof, provided that none of the 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 Credit Extensions will be required to be made during such cure period);

               8.5 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 thirty (30)
days (provided that no Credit Extensions will be made prior to the dismissal of
such Insolvency Proceeding);

               8.6 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 $250,000 or that could
reasonably be expected to have a Material Adverse Effect;

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

               8.8 Judgments. If a judgment or judgments for the payment of
money in an amount, individually or in the aggregate, of at least $250,000 shall
be rendered against Borrower and shall remain unsatisfied and unstayed for a
period of ten (10) days (provided that no Credit Extensions will be made prior
to the satisfaction or stay of such judgment); or

               8.9 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.

                                       17

<PAGE>   19
               8.10 Guaranty. If any guaranty of all or a portion of the
Obligations ceases for any reason to be in full force and effect, or any of the
circumstances described in any of Sections 8.3, 8.4 or 8.5 occurs with respect
to any Guarantor, or any Guarantor fails to perform any obligation under any
guaranty of all or a portion of the Obligations, or any Guarantor revokes or
purports to revoke any guaranty of the Obligations, or any material
misrepresentation or material misstatement exists now or hereafter in any
warranty or representation set forth in any guaranty of all or a portion of the
Obligations or in any certificate delivered to Bank in connection with such
guaranty.

        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; and

                      (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) 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 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, in order to exercise any of
Bank's rights or remedies provided herein, at law, in equity, or otherwise, but
only for so long as is reasonably required for the exercise of such right;

                      (f) 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) Dispose of the Collateral in accordance with the Code,
including 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

                                       18

<PAGE>   20
such places (including Borrower's premises) as 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;

                      (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) dispose of any Collateral; (e) make, settle, and adjust all
claims under and decisions with respect to Borrower's policies of insurance; (f)
settle and adjust disputes and claims respecting the accounts directly with
account debtors, for amounts and upon terms which Bank determines to be
reasonable; (g) to modify, in its sole discretion, any intellectual property
security agreement entered into between Borrower and Bank without first
obtaining Borrower's approval of or signature to such modification by amending
Exhibits A, B, and C, thereof, as appropriate, to include reference to any
right, title or interest in any Copyrights, Patents or Trademarks acquired by
Borrower after the execution hereof or to delete any reference to any right,
title or interest in any Copyrights, Patents or Trademarks in which Borrower no
longer has or claims to have any right, title or interest; (h) to file, in its
sole discretion, one or more financing or continuation statements and amendments
thereto, relative to any of the Collateral without the signature of Borrower
where permitted by law; and (i) to transfer the Intellectual Property Collateral
into the name of Bank or a third party to the extent permitted under the
California Uniform Commercial Code; 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 if Borrower
has not done so within 10 days of Bank's request. 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. At any time during the term of this
Agreement, 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.

               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 after reasonable notice to Borrower: (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 reasonable banking practices, 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. 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

                                       19

<PAGE>   21
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 default or 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.

               12.1 Successors and Assigns. This Agreement shall bind and inure
to the benefit of the respective successors and permitted assigns of each of the
parties; provided, however, that neither this Agreement nor any rights hereunder
may be assigned by Borrower without Bank's prior written consent, which consent
may be granted or withheld in Bank's sole discretion. Bank shall have the right
without the consent of or notice to Borrower to sell, transfer, negotiate, or
grant participation in all or any part of, or any interest in, Bank's
obligations, rights and benefits hereunder.

               12.2 Indemnification. Borrower shall defend, indemnify and hold
harmless Bank and its officers, employees, and agents against: (a) all

(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 transactions between Bank and

to Executive or any other person. The Company specifically denies that it has
any liability to or that it has done any wrongful, harassing and/or
discriminatory acts against Executive or any other person on the part of itself,

complaint, or charge of any kind with any court, governmental or administrative
agency or arbitrator against the Company or its officers, directors, agents or
employees, asserting any claims that are released in this Agreement. Executive

            (b) Executive acknowledges and agrees that this Agreement represents
a compromise of known and unknown, asserted and unasserted, and actual and
potential claims, and that neither this Agreement nor any compliance herewith or
consideration given pursuant hereto, shall be construed as an admission by the
Company of any liability whatsoever, including, but not limited to, any
liability for any violation by the Company of any right of Executive or of any

the laws established by the California Division of Labor Standards Enforcement,
e.g., Cal. Lab. Codes (S)(S) 200-272, and that all such liability is expressly
disputed and denied.

            (c) Executive further understands and acknowledges that:

                  (1) this Agreement constitutes a voluntary waiver of any and
all rights and claims he has against the Releasees as of the date of the
execution of this Agreement, including rights or claims arising under the
Federal Age Discrimination in Employment Act of 1967 ("ADEA"), 29 U.S.C. (S)(S)
621 et seq., as amended by the Older Workers' Benefit Protection Act of 1990,
except for any allegation that a breach of this Act occurred following the
Effective Date;

                  (2) he has waived rights or claims pursuant to this Agreement
in exchange for consideration, the value of which exceeds the payment or
remuneration to which he was already entitled;

                  (3) he is hereby advised that he may consult with an attorney
of his choosing concerning this Agreement prior to executing it;

                  (4) he has been afforded a period of at least twenty-one (21)
days to consider the terms of this Agreement, and in the event he should decide
to execute this Agreement in fewer than twenty-one days, he has done so with the
express understanding that he has been given and declined the opportunity to
consider this Agreement for a full twenty-one days; and

                  (5) he may revoke this Section 6(c) of the Agreement at any
time during the seven (7) days following the date of execution of this
Agreement, and this Section 6(c) of the Agreement shall not become effective or
enforceable until such revocation period has expired. Executive further
understands and acknowledges that he may revoke only Section 6(c) of this
Agreement as it relates to any claim pursuant to the Federal Age Discrimination
in Employment Act, and that such revocation, if any, will not affect the
effectiveness or enforceability of any other of the Released Matters as they are
described in Section 6(c).

      7.    Unknown Claims.
            --------------

            Executive acknowledges that there is a risk that subsequent to the
execution of this Agreement, he will incur or suffer damage, loss or injury to
persons or property that is in some way caused by or connected with Executive's
employment or his resignation therefrom, but that is unknown or unanticipated at
the time of the execution of this Agreement. Executive does hereby specifically
assume such risk and agrees that this Agreement and the releases contained
herein shall and do apply to all unknown or unanticipated results of any and all
matters caused by or connected with Executive's employment or his resignation
therefrom, as well as those currently known or

                                       4
<PAGE>

anticipated. Accordingly, Executive acknowledges that he has read the provisions
of California Civil Code Section 1542, which provides as follows:

                  "A general release does not extend to claims which the
                  creditor does not know or suspect to exist in his favor at the
                  time of executing the release, which if known to him must have
                  materially affected his settlement with the debtor."

and that he expressly waives, relinquishes and forfeits all rights and benefits
accorded by the provisions of California Civil Code Section 1542, and
furthermore waives any rights that he might have to invoke said provisions now
or in the future with respect to the Released Matters.

      8.    Ownership of Claims.
            -------------------

            Executive represents and warrants that no portion of any of the
Released Matters and no portion of any recovery or settlement to which Executive
might be entitled has been assigned or transferred to any other person, firm,
entity or corporation not a party to this Agreement, in any manner, including by
way of subrogation or operation of law or otherwise. If any claim, action,
demand or suit should be made or instituted against the Releasees or any of them
because of any such purported assignment, subrogation or transfer, Executive
agrees to indemnify and hold harmless the Releasee(s) against such claim,
action, suit or demand, including necessary expenses of investigation,
attorneys' fees and costs.

      9.    Assumption of Risk; Investigation of Facts.
            ------------------------------------------

            (a) Executive hereby expressly assumes the risk of any mistake of
fact or that the true facts might be other than or different from the facts now
known or believed to exist, and it is Executive's express intention to forever
settle, adjust and compromise any and all disputes between and among him and the
Releasees, finally and forever, and without regard to who may or may not have
been correct in their respective understandings of the facts or the law relating
thereto.

            (b) In making and executing this Agreement, Executive represents and
warrants that he has made such investigation of the facts and the law pertaining
to the matters described in this Agreement as he deems necessary, and Executive
has not relied upon any statement or representation, oral or written, made by
any other party to this Agreement with regard to any of the facts involved in
any dispute or possible dispute between the parties hereto, or with regard to
any of his rights or asserted rights, or with regard to the advisability of
making and executing this Agreement.

      10.   No Representations.
            ------------------

            Executive represents and agrees that no promises, statements or
inducements have been made to him, which caused him to sign this Agreement other
than those expressly stated in this Agreement.

            -----------------

            Executive agrees that he will refrain from taking actions or making
statements, written or oral, which disparage or defame the goodwill or
reputation of the Company, and/or its directors, officers, executives and
employees or which could adversely affect the morale of other employees of the
Company and that Executive shall not demean or disparage the Company in any
communications or other dealings with any existing or potential employees,
customers, vendors and/or stockholders.

      12.   Successors.
            ----------

executors, successors and assigns.

      13.   Arbitration.
            -----------

            (a) Any claim or controversy arising out of or relating to this
Agreement or any breach thereof between Executive and the Company shall be
submitted to arbitration in Los Angeles County, California, before an
experienced employment arbitrator licensed to practice law in California and
selected in accordance with the Model Employment Arbitration Procedures of the
American Arbitration Association, as the exclusive remedy for such claim or
controversy. Either party desiring to arbitrate shall give written notice to the
other party within a reasonable period of time after the party becomes aware of
the need for arbitration. The decision of the arbitrator shall be final and
binding. Judgment on any award rendered by such arbitrator may be entered in any
court having jurisdiction over the subject matter of the controversy. The
prevailing party shall receive an award of costs and expenses related to the
arbitration, including attorneys' fees. The fees and costs of the arbitrator and
the cost of any record or transcript of the arbitration shall be borne by the
losing party.

            (b) Should Executive or the Company institute any legal action or
administrative proceeding with respect to any claim waived by this Agreement or
pursue any dispute or matter covered by this paragraph by any method other than
said arbitration, the responding party shall be entitled to recover from the
other party all damages, costs, expenses and attorneys' fees incurred as a
result of such action.

      14.   Tender of Severance Payments as a Condition to Challenge This
            -------------------------------------------------------------
            Agreement
            ---------

            Should Executive attempt to challenge the enforceability of this
Agreement, as a further limitation on any right to make such a challenge,
Executive shall initially submit to the Company the total proceeds provided to
him in connection with this Agreement plus interest at the standard statutory
rate, and invite the Company to retain such monies and agree with Executive to
cancel this Agreement. In the event the Company accepts this offer, the Company
shall retain such monies and this Agreement shall be canceled. In the event the
Company does not accept such offer, the Company shall so notify Executive and
shall place such monies into an interest-bearing escrow account pending
resolution of the dispute between Executive and the Company as to whether this
Agreement shall be set aside and/or otherwise rendered unenforceable.
