2        LOAN AND TERMS OF PAYMENT

2.1      CREDIT EXTENSIONS.

2.1.1    REVOLVING ADVANCES.

         (a) Bank will make Advances not exceeding (i) the Committed Revolving

8        EVENTS OF DEFAULT

         Any one of the following is an Event of Default:

8.1      PAYMENT DEFAULT.

         If Borrower fails to pay any of the Obligations when due;

8.2      COVENANT DEFAULT.

         If Borrower does not perform any obligation in Section 6 or violates
any covenant in Section 7 or does not perform or observe any other material
term, condition or covenant in this Agreement, Exim Loan Documents, any Loan
Documents, or in any agreement between Borrower and Bank and as to any default
under a term, condition or covenant that can be cured, has not cured the default
within 10 days after it occurs, or if the default cannot be cured within 10 days
or cannot be cured after Borrower's attempts within 10 day period, and the
default may be cured within a reasonable time, then Borrower has an additional
period (of not more than 30 days) to attempt to cure the default. During the
additional time, the failure to cure the default is not an Event of Default (but
no Credit Extensions will be made during the cure period);

8.3      MATERIAL ADVERSE CHANGE.

         (i) If there occurs a material impairment in the perfection or priority
of the Bank's security interest in the Collateral or in the value of such
Collateral which is not covered by adequate insurance or (ii) if the Bank
determines, based upon information available to it and in its reasonable
judgment, that there is a reasonable likelihood that Borrower will fail to
comply with one or more of the financial covenants in Section 6 during the next
succeeding financial reporting period.

8.4      ATTACHMENT.

         If any material portion of Borrower's assets is attached, seized,
levied on, or comes into possession of a trustee or receiver and the attachment,
seizure or levy is not removed in 10 days, or if Borrower is enjoined,
restrained, or prevented by court order from conducting a material part of its
business or if a judgment or other claim becomes a Lien on a material portion of
Borrower's assets, or if a notice of lien, levy, or assessment is filed against
any of Borrower's assets by any government agency and not paid within 10 days
after Borrower receives notice. These are not Events of Default if stayed or if
a bond is posted pending contest by Borrower (but no Credit Extensions will be
made during the cure period);

8.5      INSOLVENCY.

         If Borrower becomes insolvent or if Borrower begins an Insolvency
Proceeding or an Insolvency Proceeding is begun against Borrower and not
dismissed or stayed within 30 days (but no Credit Extensions will be made before
any Insolvency Proceeding is dismissed);


                                      11
<PAGE>

8.6      OTHER AGREEMENTS.

         If there is a default in any agreement between Borrower and a third
party that gives the third party the right to accelerate any Indebtedness
exceeding $100,000 or that could cause a Material Adverse Change;

8.7      JUDGMENTS.

         If a money judgment(s) in the aggregate of at least $50,000 is rendered
against Borrower and is unsatisfied and unstayed for 10 days (but no Credit
Extensions will be made before the judgment is stayed or satisfied); or

8.8      MISREPRESENTATIONS.

         If Borrower or any Person acting for Borrower makes any material
misrepresentation or material misstatement now or later in any warranty or
representation in this Agreement or in any writing delivered to Bank or to
induce Bank to enter this Agreement or any Loan Document.

9        BANK'S RIGHTS AND REMEDIES

9.1      RIGHTS AND REMEDIES.

         When an Event of Default occurs and continues Bank may, without notice
or demand, do any or all of the following:

         (a) Declare all Obligations immediately due and payable (but if an
Event of Default described in Section 8.5 occurs all Obligations are immediately
due and payable without any action by Bank);

         (b) Stop advancing money or extending credit for Borrower's benefit
under this Agreement or under any other agreement between Borrower and Bank;

         (c) Settle or adjust disputes and claims directly with account debtors
for amounts, on terms and in any order that Bank considers advisable;

         (d) Make any payments and do any acts it considers necessary or
reasonable to protect its security interest in the Collateral. Borrower will
assemble the Collateral if Bank requires and make it available as Bank
designates. Bank may enter premises where the Collateral is located, take and
maintain possession of any part of the Collateral, and pay, purchase, contest,
or compromise any Lien which appears to be prior or superior to its security
interest and pay all expenses incurred. Borrower grants Bank a license to enter
and occupy any of its premises, without charge, to exercise any of Bank's rights
or remedies;

         (e) Apply to the Obligations any (i) balances and deposits of Borrower
it holds, or (ii) any amount held by Bank owing to or for the credit or the
account of Borrower;

         (f) Ship, reclaim, recover, store, finish, maintain, repair, prepare
for sale, advertise for sale, and sell the Collateral; and

         (g) Dispose of the Collateral according to the Code.

9.2      POWER OF ATTORNEY.

         Effective only when an Event of Default occurs and continues, Borrower
irrevocably appoints Bank as its lawful attorney to: (i) endorse Borrower's name
on any checks or other forms of payment or security; (ii) sign Borrower's name
on any invoice or bill of lading for any Account or drafts against account
debtors, (iii) make, settle, and adjust all claims under Borrower's insurance
policies; (iv) settle and adjust disputes and claims about the Accounts directly
with account debtors, for amounts and on 


                                      12
<PAGE>

terms Bank determines reasonable; and (v) transfer the Collateral into the 
name of Bank or a third party as the Code permits. Bank may exercise the 
power of attorney to sign Borrower's name on any documents necessary to 
perfect or continue the perfection of any security interest regardless of 
whether an Event of Default has occurred. Bank's appointment as Borrower's 
attorney in fact, and all of Bank's rights and powers, coupled with an 
interest, are irrevocable until all Obligations have been fully repaid and 
performed and Bank's obligation to provide Credit Extensions terminates.

9.3      ACCOUNTS COLLECTION.

         When an Event of Default occurs and continues, Bank may notify any
Person owing Borrower money of Bank's security interest in the funds and verify
the amount of the Account. Borrower must collect all payments in trust for Bank
and, if requested by Bank, immediately deliver the payments to Bank in the form
received from the account debtor, with proper endorsements for deposit.

9.4      BANK EXPENSES.

         If Borrower fails to pay any amount or furnish any required proof of
payment to third persons Bank may make all or part of the payment or obtain
insurance policies required in Section 6.6, and take any action under the
policies Bank deems prudent. Any amounts paid by Bank are Bank Expenses and
immediately due and payable, bearing interest at the then applicable rate and
secured by the Collateral. No payments by Bank are deemed an agreement to make
similar payments in the future or Bank's waiver of any Event of Default.

9.5      BANK'S LIABILITY FOR COLLATERAL.

         If Bank complies with reasonable banking practices it is not liable
for: (a) the safekeeping of the Collateral; (b) any loss or damage to the
Collateral; (c) any diminution in the value of the Collateral; or (d) any act or
default of any carrier, warehouseman, bailee, or other person. Borrower bears
all risk of loss, damage or destruction of the Collateral.

9.6      REMEDIES CUMULATIVE.

         Bank's rights and remedies under this Agreement, the Loan Documents,
and all other agreements are cumulative. Bank has all rights and remedies
provided under the Code, by law, or in equity. Bank's exercise of one right or
remedy is not an election, and Bank's waiver of any Event of Default is not a
continuing waiver. Bank's delay is not a waiver, election, or acquiescence. No
waiver is effective unless signed by Bank and then is only effective for the
specific instance and purpose for which it was given.

9.7      DEMAND WAIVER.

         Borrower waives demand, 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 held by Bank on which Borrower is
liable.

10       NOTICES

         All notices or demands by any party about this Agreement or any other
related agreement must be in writing and be personally delivered or sent by an
overnight delivery service, by certified mail, postage prepaid, return receipt
requested, or by telefacsimile to the addresses set forth at the beginning of

         (e) Liens incurred in the extension, renewal or refinancing of the
indebtedness secured by Liens described in (a) through (c), BUT any extension,

         "PERSON" is any individual, sole proprietorship, partnership, limited
liability company, joint venture, company association, trust, unincorporated
organization, association, corporation, institution, public benefit corporation,
firm, joint stock company, estate, entity or government agency.

         "PREPAYMENT FEE" is a fee on any portion of the Obligations with a
fixed interest rate (the "Fixed Obligations") paid before the payment due date.
"Base Interest Rate" means Bank's initial cost of funding the Fixed Obligations.
The Prepayment Fee is calculated as follows: First, Bank determines a "Current
Market Rate" based on what the Bank would receive if it loaned the amount on the
prepayment date in a wholesale funding market matching maturity, principal
amount and principal and interest payment dates (the aggregate payments received
are the "Current Market Rate Amount"). Bank may select any wholesale funding
market rate as the Current Market Rate. Second, Bank will take the prepayment
amount and calculate the present value of each principal and interest payment
which, without prepayment, the Bank would have received during the term of the
Fixed Obligations using the Base Interest Rate. The sum of the present value
calculations is the "Mark to Market Amount." Third, the Bank will subtract the
Mark to Market Amount from the Current Market Rate Amount. Any amount greater
than zero is the Prepayment Fee.

         "PRIME RATE" is Bank's most recently announced "prime rate," even if it
is not Bank's lowest rate.

         "QUICK ASSETS" is, on any date, the Borrower's consolidated,
unrestricted cash, cash equivalents, net billed accounts receivable and
investments with maturities of fewer than 12 months determined according to
GAAP.

         "RESPONSIBLE OFFICER" is each of the Chief Executive Officer, the
President, the Chief Financial Officer and the Controller of Borrower.

         "REVOLVING MATURITY DATE" is April 20, 2000.

         "SCHEDULE" is any attached schedule of exceptions.

         "SUBORDINATED DEBT" is debt incurred by Borrower subordinated to
Borrower's debt to Bank (and identified as subordinated by Borrower and Bank).

         "SUBSIDIARY" is for any Person, or any other business entity of which
more than 50% of the voting stock or other equity interests is owned or
controlled, directly or indirectly, by the Person or one or more Affiliates of
the Person.

         "TANGIBLE NET WORTH" is, on any date, the consolidated total assets of
Borrower and its Subsidiaries MINUS, (i) any amounts attributable to (a)
goodwill, (b) intangible items such as unamortized debt discount and expense,
Patents, trade and service marks and names, Copyrights and research and
development expenses except prepaid expenses, and (c) reserves not already
deducted from assets, and (ii) Total Liabilities.

         "TERM LOAN #1" is a loan of $563,128.12

         "TERM LOAN #2" is a loan of $571,092.15

         "TERM LOAN #1 MATURITY DATE" is June 29, 2003.

         "TERM LOAN #2 MATURITY DATE" is November 29, 2001.


                                      19

         "TOTAL LIABILITIES" is on any day, obligations that should, under GAAP,
be classified as liabilities on Borrower's consolidated balance sheet, including
all Indebtedness, and current portion Subordinated Debt allowed to be paid, but
excluding all other Subordinated Debt.

         "TREASURY RATE". Treasury Rate is the Treasury Yield Percentage based
on the average weekly yield (of the week ending figures) in the most recent
Federal Reserve Statistical Release on actively traded U.S. Treasury obligations
of similar maturity to the principal being repaid or if a Statistical Release is
not published, the arithmetic average (to the nearest .01%) of the per annum
yields to maturity for each Business Day during the week (ending at least two
Business Days before the determination is made) of all actively traded
marketable United States Treasury fixed interest rate securities with a constant
maturity of, or not more than 30 days longer or shorter than the average life of
the principal and interest payments that are being prepaid (excluding securities
that can be surrendered at face value to pay Federal estate tax, or which
provide for tax benefits to the holder).
