6.2    FINANCIAL STATEMENTS, REPORTS, CERTIFICATES.

       (a) Borrower will deliver to Bank: (i) within 5 days of filing, copies of

10-Q and 8-K filed with the Securities and Exchange Commission; (ii) a prompt

Borrowing Base Certificate signed by a Responsible Officer in the form of
Exhibit C, with aged listings of accounts receivable and accounts payable.

       (c) Borrower will deliver to Bank a Compliance Certificate signed by a
Responsible Officer in the form of Exhibit D, together with its 10Q and 1OK

       (d) Bank has the right to audit Borrower's Collateral at Borrower's
expense, but the audits will be conducted no more often than every year and will
be performed after Closing Date and the cost of such audit shall not exceed

6.3.   TAXES.

       Borrower will make, and cause each Subsidiary to make, timely payment of

6.4    INSURANCE.

       Borrower will keep its business and the Collateral insured for risks and
in amounts, as Bank requests. Insurance policies will be in a form, with
companies, and in amounts that are satisfactory to Bank. All property policies
will have a lender's loss payable endorsement showing Bank as an additional loss
payee and all liability policies will show the Bank as an additional insured and
provide that the insurer must give Bank at least 20 days notice before canceling
its policy.  At Bank's request, Borrower will deliver certified copies of 
policies and evidence of all premium payments.  Proceeds payable under any 
policy will, at Bank's option, be payable to Bank on account of the Obligations.
Statutory notice regarding insurance.

                                       WARNING

       Unless you provide us with evidence of the insurance coverage as required
by our contract or loan agreement, we may purchase insurance at your expense to
protect our interest.  This insurance may, but need not, also protect your
interest.  If the collateral becomes damaged, the coverage we purchase may not
pay any claim you make or any claim made against you.  You may later cancel this
coverage by providing evidence that you have obtained property coverage
elsewhere.

       You are responsible for the cost of any insurance purchased by us. The
cost of this insurance may be added to your contract or loan balance. If the
cost is added to your contract or loan balance, the interest rate on the 
underlying contract or loan will apply to this added amount. The effective 
date of coverage may be the date your prior coverage lapsed or the date you
failed to provide proof of coverage.

       This coverage we purchased may be considerably more expensive than
insurance you can obtain on your own and may not satisfy any need for property
damage coverage or any mandatory liability insurance requirements imposed by
applicable law.

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 an 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 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 6.4, and take


                                          12

<PAGE>

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.

conflicts of law. Borrower and Bank each submit to the exclusive jurisdiction of

       "PREPAYMENT FEE" means a fee on any portion of the Equipment Advances
with a fixed interest rate (the "Fixed Obligations") that is paid before the
payment due date. 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 (such
aggregate payments received being deemed the "Current Market


                                          18

<PAGE>

Rate Amount"). Bank, in its sole discretion, 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 term of the Fixed
Obligations using the applicable interest rate set forth in this Agreement. 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 Senior Vice President, Operations
and Senior Vice President-Corporate Development, Chief Executive Officer, the
President, the Chief Financial Officer and the Controller of Borrower.

       "REVOLVING MATURITY DATE" is April 22,2001.

       "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.

       "TOTAL LIABILITIES" is on any day, obligations that should, under GAAP,

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).
