                  2.1.1  Revolving Credit Facility.
                         --------------------------

                  During the Revolving Credit Commitment Period, the Lender
agrees to make advances under the Revolving Credit requested by the Borrower
from time to time provided that after giving effect to the Borrower's request,

                         Credit; LenderProtection Loans.
                         -------------------------------

                  The Borrowers may borrow under the Revolving Credit Facility
on any Business Day. Advances under the Revolving Credit shall be deposited to a
demand deposit account of the Company with the Lender or shall be otherwise
applied as directed by the Company, which direction the Lender may require to be
in writing, provided, however, the Lender may make the advances referred to in
Section 2.2.3, without the direction of the Company. Except for advances made
under the Revolving Credit by the Lender which the Lender is authorized to make
under this Agreement, not later than 11:00 a.m. (Eastern Standard Time) on the
date of the requested borrowing, the Company shall give the Lender oral or
written notice (a "Loan Notice") of the amount and (if requested by the Lender)
the purpose of the requested borrowing. Any oral Loan Notice shall be confirmed
in writing by the Company within three (3) Business Days after the making of the
requested advance under the Revolving Credit. Each Loan Notice shall be
irrevocable.

                  In addition, each of the Borrowers hereby irrevocably
authorizes the Lender at any time and from time to time, without further request
from or notice to the Borrowers, to make advances under the Revolving Credit,
and to establish, without duplication, reserves against the Borrowing Base,
which the Lender, in its sole and absolute discretion, deems necessary or
appropriate to protect the interests of the Lender, including, without
limitation, advances and reserves under the Revolving Credit made to cover debit
balances in the Revolving Loan Account, principal of, and/or interest on, any
Revolving Credit, the Obligations (including, without limitation, any Letter of
Credit Obligations), and/or Enforcement Costs, prior to, on, or after the
termination of other advances under this Agreement, regardless of whether the
outstanding principal amount of the Revolving Credit that the Lender may advance
or reserve hereunder exceeds the Total Revolving Credit Committed Amount or the
Borrowing Base,

                                       21
<PAGE>

provided, however, that the Lender agrees to give the Company two (2) Business
Days prior notice of any such advances, other than advances for the purposes of
covering debit balances in the Revolving Loan Account, principal of, and/or
interest on, any Revolving Credit, and the payment of any Fees, unless the
Lender in its exercise of its reasonable discretion determines that the failure
to provide such notice could result in a Material Adverse Effect.

                  2.1.3  Borrowing Base.
                         ---------------

                  As used in this Agreement, the term "Borrowing Base" means at
any time, an amount equal to the aggregate of (a) ninety percent (90%) of the
amount of Eligible Receivables derived from Government Contracts, plus (b)
eighty five percent (85%) of Eligible Receivables derived from contracts other
than Government Contracts.

                  The Borrowing Base shall be computed based on the Borrowing
Base Report most recently delivered to and accepted by the Lender in its sole
and absolute discretion. In the event the Borrowers fail to furnish a Borrowing
Base Report required by Section 2.1.4 (Borrowing Base Report), or in the event
the Lender believes that a Borrowing Base Report is no longer accurate, the
Lender may, in its sole and absolute discretion exercised from time to time and
without limiting other rights and remedies under this Agreement, suspend the
making of or limit advances under the Revolving Credit. The Borrowing Base shall
be subject to reduction by amounts credited to the Collateral Account since the
date of the most recent Borrowing Base Report and by the amount of any
Receivable which was included in the Borrowing Base but which the Lender
determines fails to meet the respective criteria applicable from time to time
for Eligible Receivables.

                  If at any time the total of the aggregate principal amount of
the Revolving Credit and Outstanding Letter of Credit Obligations exceeds the
Borrowing Base, a borrowing base deficiency ("Borrowing Base Deficiency") shall
exist. Each time a Borrowing Base Deficiency exists, the Borrower, at the sole
and absolute discretion of the Lender exercised from time to time, shall pay the
Borrowing Base Deficiency within two Business Days of DEMAND to the Lender.

                  Without implying any limitation on the Lender's discretion
with respect to the Borrowing Base, the criteria for Eligible Receivables
contained in the definition of Eligible Receivables are in part based upon the
business operations of the Borrowers existing on or about the Closing Date and
upon information and records furnished to the Lender by the Borrowers. If at any
time or from time to time hereafter, the business operations of the Borrowers
change or such information and records furnished to the Lender is incorrect or
misleading, the Lender in its discretion, may at any time and from time to time
during the duration of this Agreement change such criteria or add new criteria.
The Lender may communicate such changed or additional criteria to the Borrowers
from time to time either orally or in writing.

                  2.1.4  Borrowing Base Report.
                         ----------------------

supporting and other information, as the Lender may from time to time request,
including, but not limited to, a report containing a detailed aging of all
accounts payable by supplier, in such detail, and accompanied by such supporting
information, as the Lender may from time to time reasonably request. Upon the
Lender's request and upon the creation of any Receivables, or at such intervals
as the Lender may require, the Borrowers will provide the Lender with (a)
confirmatory assignment schedules; (b) copies of Account Debtor invoices; (c)
evidence of shipment or delivery; and (d) such further schedules, documents
and/or information regarding the Receivables as the Lender may reasonably
require. The items to be provided under this subsection shall be in form
satisfactory to the Lender, and certified as true and correct by a Responsible
Officer, and delivered to the Lender from time to time solely for the Lender's
convenience in maintaining records of the Collateral. Any Borrower's failure to

otherwise limit the Liens of the Lender in the Collateral.

Revolving Credit Note, the excess shall bear interest at the rates provided from
time to time for advances under the Revolving Credit evidenced by the Revolving
Credit Note and shall be payable, with accrued interest, within two Business
Days of DEMAND.  The Revolving Credit Note shall not operate as a novation of
any of the Obligations or nullify, discharge, or release any such Obligations or

the provisions of this Agreement.

receipt of the Items of Payment. The Items of Payment shall be deposited in
precisely the form received, except for the endorsements of the Borrowers where
necessary to permit the collection of any such Items of Payment, each Borrower
hereby agreeing to make such endorsement. In the event any Borrower shall fail
to do so, the Lender is hereby authorized by each Borrower to make the
endorsement in the name of such Borrower. Prior to such a deposit, none of the
Borrowers will not commingle any Items of Payment with any of the other funds or
property of any other Borrower, but will hold them separate and apart in trust
and for the account of the Lender.

                  In addition, if so directed by the Lender, the Borrowers shall
direct the mailing of all Items of Payment from its Account Debtors to a post-
office box designated by the Lender, or to such other additional or replacement
post-office boxes pursuant to the request of the Lender from time to time
(collectively, the "Lockbox"). The Lender shall have unrestricted and exclusive
access to the Lockbox.

                  Each Borrower hereby authorizes the Lender to inspect all
Items of Payment, endorse all Items of Payment in the name of each Borrower, and
deposit Items of Payment in the Collateral Account. The Lender reserves the
right, exercised in its sole and absolute discretion from time to time, to
provide to the Collateral Account credit prior to final collection of an Item of
Payment and to disallow credit for any Item of Payment which is unsatisfactory
to the Lender. However, if the Lender disallows credit for any Item of Payment,
the Lender will give the Company notice to that effect and will, upon request,
release such Item of Payment to the Company. In the event Items of Payment are
returned to the Lender for any reason whatsoever, the Lender may, in the
exercise of its discretion from time to time, forward such Items of Payment a
second time. Any returned Items of Payment shall be charged back to the
Collateral Account, the Revolving Loan Account, or other account, as
appropriate.

                  The Lender will apply the whole or any part of the collected
funds credited to the Collateral Account against the Revolving Credit (or with
respect to Items of Payment which are not proceeds of accounts or inventory or
after a Default or Event of Default, against any of the Obligations) or credit
such collected funds to the depository account of the Borrowers with the Lender
(or an Affiliate of the Lender), the order and method of such application to be
in the sole discretion of the Lender, provided, however, that if any collected
funds are credited to the Collateral Account at a time when there are no
outstanding and unpaid Obligations, the Lender will, on the day the funds are so
credited, credit them to the depository

                                       24
<PAGE>

account of a Borrower with the Lender (or an Affiliate of the Lender) or to such
other account as the Company has specified for the purpose, and prior to the
occurrence and continuance of any Default or Event of Default, the Lender will
apply collected funds, first toward the payment of amounts outstanding under
Base Rate Loans, and then toward payment of amounts outstanding under Eurodollar
Loans, provided, however, that unless directed to by the Company in writing, the
Lender will not apply payments to the Eurodollar Loans prior to the last day of
any Interest Period.

                  2.1.9  Revolving Loan  Account.
                         ------------------------

                  The Lender will establish and maintain a loan account on its
books (the "Revolving Loan Account") to which the Lender will (a) debit (i) the
                                                                  -----
principal amount of each advance under the Revolving Credit made by the Lender
hereunder as of the date made, (ii) the amount of any interest accrued on the
Revolving Credit as and when due, and (iii) any other amounts due and payable by
the Borrowers to the Lender from time to time under the provisions of this
Agreement in connection with the Revolving Credit, including, without
limitation, Enforcement Costs, Fees, late charges, and service, collection and
audit fees, as and when due and payable, and (b) credit all payments made by the
                                                 ------
Borrowers to the Lender on account of the Revolving Credit as of the date made
including, without limitation, funds credited to the Revolving Loan Account from
the Collateral Account. All credit entries to the Revolving Loan Account are
conditional and shall be readjusted as of the date made if final and
indefeasible payment is not received by the Lender in cash or solvent credits.
The Borrowers hereby promise to pay to the order of the Lender, within two (2)
Business Days after DEMAND, an amount equal to the excess, if any, of all debit
entries over all credit entries recorded in the Revolving Loan Account under the
provisions of this Agreement. Any and all periodic or other statements or
reconciliations, and the information contained in those statements or
reconciliations, of the Revolving Loan Account shall be final, binding and
conclusive upon the Borrowers in all respects, absent manifest error, unless the
Lender receives specific written objection thereto from the Borrowers within
thirty (30) Business Days after such statement or reconciliation shall have been
sent by the Lender.

                  2.1.10 Revolving Credit Unused Line Fee.
                         ---------------------------------

                  The Borrowers shall pay to the Lender a monthly revolving
credit facility fee (collectively, the "Revolving Credit Unused Line Fees" and
individually, a "Revolving Credit Unused Line Fee") in an amount equal to thirty
basis points (.30%) per annum on the average daily unused and undisbursed
portion of the Revolving Credit Committed Amount in effect from time to time
accruing during each calendar month. The accrued and unpaid portion of the
Revolving Credit Unused Line Fee shall be paid by the Borrowers to the Lender on
the first day of each month, commencing on the first such date following the
date hereof, and on the Revolving Credit Termination Date.

                  2.1.11 Early Termination Fee.
                         ----------------------

                  In the event of the termination by, or on behalf of, the
Borrowers, of the Revolving Credit Commitment, the Borrowers shall pay a fee
(the "Early Termination Fee") equal to the following amounts at the following
times:

          August 8, 2003                               Committed Amount

          Payment of the Revolving Credit in whole or in part by or on behalf of
the Borrowers, by court order or otherwise, following and as a result of the
institution of any bankruptcy proceeding by or against the Borrowers, shall be
deemed to be a prepayment of the Revolving Credit subject to the Early
Termination Fee provided in this subsection.

     Section 2.2  The Letter of Credit Facility.
                  ------------------------------

                  2.2.1  Letters of Credit.
                         ------------------

                  Subject to and upon the provisions of this Agreement, and as a
part of the Revolving Credit Commitment, the Borrower may, upon the prior
approval of the Lender, obtain standby letters of credit (as the same may from
time to time be amended, supplemented or otherwise modified, each a "Letter of
Credit" and collectively the "Letters of Credit") from the Lender from time to
time from the Closing Date until the Business Day preceding the Revolving Credit
Termination Date. The Borrower will not be entitled to obtain a Letter of Credit
hereunder unless (a) after giving effect to the request, the outstanding
principal balance of the Revolving Credit and of the Letter of Credit
Obligations would not exceed the lesser of (i) the Revolving Credit Committed
Amount, or (ii) the most current Borrowing Base and (b) the sum of the aggregate
face amount of the then outstanding Letters of Credit (including the face amount
of the requested Letter of Credit) does not exceed Ten Million Dollars
($10,000,000).

                  2.2.2  Letter of Credit Fees.
                         ----------------------

                  The Borrowers shall pay to the Lender, a letter of credit fee
(each a "Letter of Credit Fee" and collectively the "Letter of Credit Fees") in
an amount equal to two percent (2%) per annum of the amount of the Letter of
Credit. Such Letter of Credit Fees shall be paid monthly in arrears on the first
day of the first month after the opening of the Letter of Credit and on the
first day of each month thereafter. In addition, the Borrower shall pay to the
Lender any and all additional issuance, negotiation, processing, transfer or
other fees to the extent and as and when required by the provisions of any
Letter of Credit Agreement; such additional fees are included in and a part of
the "Fees" payable by the Borrower under the provisions of this Agreement.
Subsequent to an Event of Default, the Letter of Credit Fee shall be increased
to the Post-Default Rate on the face amount of each Letter of Credit.

                  2.2.3  Terms of Letters of Credit.
                         ---------------------------

                  Each Letter of Credit shall (a) be opened pursuant to a Letter
of Credit Agreement, and (b) expire on a date not later than the Business Day
preceding the Revolving Credit Expiration Date; provided, however, if any Letter
of Credit does have an expiration date later than the Business Day preceding the
Revolving Credit Termination Date, as of the Business Day preceding the
Revolving Credit Termination Date an advance of the Revolving Credit

                                       26
<PAGE>

Facility shall be made by the Lender in the face amount of such Letter of Credit
(or Letters of Credit) and the proceeds thereof shall be deposited in an account
titled in the name of the Lender as trustee for the Borrower, which account will
bear interest in accordance with the Lender's standard procedures and practices
for escrow accounts. The proceeds of the trustee account referred to in the
immediately preceding sentence shall be held as collateral for the Letter of
Credit (or Letters of Credit) and in the event of a draw under the Letter of
Credit (or Letters of Credit), used to pay any such draw. The balance remaining
in such account after the expiration of such Letter of Credit (or Letters of
Credit) and the indefeasible repayment in full of the Obligations will be
released to an account of the Company's with the Lender specified by the
Company.

                  The aggregate face amount of all Letters of Credit at any one
time outstanding and issued by the Lender pursuant to the provisions of this
Agreement, plus the amount of any unpaid Letter of Credit Fees accrued or
scheduled to accrue thereon, and less the aggregate amount of all drafts issued
under or purporting to have been issued under such Letters of Credit that have
been paid by the Lender, is herein called the "Outstanding Letter of Credit
Obligations".

                  Except where an advance is made as provided above for a Letter
of Credit having an expiration date beyond the Revolving Credit Termination
Date, if the Lender makes payment under a draft presented under a Letter of
Credit and not otherwise reimbursed by the Borrowers on the date such
reimbursement is due under this Agreement or the relevant Letter of Credit
Documents, provided no Default or Event of Default has occurred and is then
continuing and further provided, that after making an advance in the amount of
such draft the outstanding Obligations will not exceed the Borrowing Base, then
the amount of such draft shall automatically become an advance under the
Revolving Credit Facility bearing interest at the Base Rate, and the Lender will
apply the proceeds of such advance to the repayment on such date of the draft
presented for payment under such Letter of Credit.

                  2.2.4  Procedure for Letters of Credit.
                         --------------------------------

                  The Borrower shall give the Lender written notice at least
three (3) Business Days prior to the date on which a Letter of Credit is
requested to be opened of its request for a Letter of Credit. Such notice shall
be accompanied by a duly executed and delivered Letter of Credit Agreement. Upon
receipt of the Letter of Credit Agreement, the Lender shall process such Letter
of Credit Agreement in accordance with its customary procedures and open such
Letter of Credit on the Business Day specified in such notice.

                  2.2.5  Change in Law; Increased Cost.
                         ------------------------------

                  If any change in any law or regulation or in the
interpretation thereof by any court or other Governmental Authority charged with
the administration thereof shall either (a) impose, modify or deem applicable
any reserve, special deposit or similar requirement against Letters of Credit
issued by the Lender, or (b) impose on the Lender any other condition regarding
this Agreement or any Letter of Credit, and the result of any event referred to
in clauses (a) or (b) above shall be to increase the cost to the Lender of
issuing, maintaining or extending the Letter of Credit or the cost to the Lender
of funding any obligation under or in connection with the Letter of Credit,
then, upon demand by the Lender, accompanied by a

                                       27
<PAGE>

statement in reasonable detail explaining the nature and calculation of the
increased cost, the Borrower shall immediately pay to the Lender from time to
time as specified by the Lender, additional amounts which shall be sufficient to
compensate the Lender for such increased cost, together with interest on each
such amount from the date demanded until payment in full thereof at a rate per
annum equal to the then highest current rate of interest on the Revolving
Credit. A certificate as to such increased cost incurred by the Lender,
submitted by the Lender to the Borrower, shall be conclusive, absent manifest
error.

     Section 2.3  General Financing Provisions.
                  -----------------------------

                  2.3.1  Borrowers' Representatives.
                         ---------------------------

                  The Borrowers hereby represent and warrant to the Lender that
each of them will derive benefits, directly and indirectly, from each advance
under the Revolving Credit Facility, both in their separate capacity and as a
member of the integrated group to which each of the Borrowers belong, and
because the successful operation of the integrated group is dependent upon the
continued successful performance of the functions of the integrated group as a
whole, because (a) the terms of the consolidated financing provided under this
Agreement are more favorable than otherwise would be obtainable by the Borrowers
individually, and (b) the Borrowers' additional administrative and other costs
and reduced flexibility associated with individual financing arrangements which
would otherwise be required if obtainable would substantially reduce the value
to the Borrowers of the financing. The Borrowers in the discretion of their
respective managements are to agree among themselves as to the allocation of the
proceeds of each advance made under the Revolving Credit, provided, however,
that the Borrowers shall be deemed to have represented and warranted to the
Lender at the time of allocation that each benefit and use of proceeds is a
Permitted Use.

                  For administrative convenience, each Borrower hereby
irrevocably appoints the Company as the Borrower's attorney-in-fact, with power
of substitution (with the prior written consent of the Lender in the exercise of
its sole and absolute discretion), in the name of the Company or in the name of
any Borrower or otherwise to take any and all actions with respect to the this
Agreement, the other Financing Documents, the Obligations and/or the Collateral
(including, without limitation, the proceeds thereof) as the Company may so
elect from time to time, including, without limitation, actions to (i) request
advances under the Revolving Credit, and direct the Lender to disburse or credit
the proceeds of any advance made under the Revolving Credit directly to an
account of the Company, any one or more of the Borrowers or otherwise, which
direction shall evidence the making of such advance under the Revolving Credit
and shall constitute the acknowledgment by each of the Borrowers of the receipt
of the proceeds of such advance under the Revolving Credit, (ii) enter into,
execute, deliver, amend, modify, restate, substitute, extend and/or renew this
Agreement, any Additional Borrower Joinder Supplement, any other Financing
Documents, security agreements, mortgages, deposit account agreements,
instruments, certificates, waivers, letter of credit applications, releases,
documents and agreements from time to time, and (iii) endorse any check or other
item of payment in the name of the Borrower or in the name of the Company. The
foregoing appointment is coupled with an interest, cannot be revoked without the
prior written consent of the Lender, and may be exercised from time to time
through the Company's duly authorized officer, officers or other Person or
Persons designated by the Company to act from time to time on behalf of the
Company.

                                       28
<PAGE>

                  Each of the Borrowers hereby irrevocably authorizes the Lender
(in its sole discretion) to make advances under the Revolving Credit to the
Company pursuant to the provisions of this Agreement upon the written, oral or
telephone request of any one or more of the Persons who is from time to time a
Responsible Officer of the Company under the provisions of the most recent
certificate of corporate resolutions and/or incumbency of the Company on file
with the Lender.

                  The Lender assumes no responsibility or liability for any
errors, mistakes, and/or discrepancies (other than those due solely to the
Lender's gross negligence or willful misconduct) in the oral, telephonic,
written or other transmissions of any instructions, orders, requests and
confirmations between the Lender and the Borrowers in connection with the Credit
Facilities, any advance under the Revolving Credit or any other transaction in
connection with the provisions of this Agreement. Without implying any
limitation on the joint and several nature of the Obligations, the Lender agrees
that, notwithstanding any other provision of this Agreement, the Borrowers may
create reasonable inter-company indebtedness between or among the Borrowers with
respect to the allocation of the benefits and proceeds of the advances and
Credit Facilities under this Agreement. The Borrowers agree among themselves,
and the Lender consents to that agreement, that each Borrower shall have rights
of contribution from all of the other Borrowers to the extent such Borrower
incurs Obligations in excess of the proceeds of the Revolving Credit received
by, or allocated to purposes for the direct benefit of, such Borrower. All such
indebtedness and rights shall be, and are hereby agreed by the Borrowers to be,
subordinate in priority and payment to the indefeasible repayment in full in
cash of the Obligations, and, unless the Lender agrees in writing otherwise,
shall not be exercised or repaid in whole or in part until all of the
Obligations have been indefeasibly paid in full in cash. The Borrowers agree
that all of such inter-company indebtedness and rights of contribution are part
of the Collateral and secure the Obligations. Each Borrower hereby waives all
rights of counterclaim, recoupment and offset between or among the Borrowers
arising on account of that indebtedness and otherwise. Each Borrower shall not
evidence the inter-company indebtedness or rights of contribution by note or
other instrument, and shall not secure such indebtedness or rights of
contribution with any Lien or security. Notwithstanding anything contained in
this Agreement to the contrary, the amount covered by each Borrower under the
Obligations (including, without limitation, Section 2.3.12 (Guaranty)) shall be
limited to an aggregate amount (after giving effect to any collections from,
rights to receive contribution from or payments made by or on behalf of any
other Borrower in respect of the Obligations) which, together with other amounts
owing by such Borrowers to the Lender under the Obligations, is equal to the
largest amount that would not be subject to avoidance under the Bankruptcy Code
or any applicable provisions of any applicable, comparable state or other Laws.

                  2.3.2  Use of Proceeds of the Revolving Credit.
                         ----------------------------------------

                  The proceeds of each advance under the Revolving Credit shall
be used by the Borrowers for Permitted Uses, and for no other purposes except as
may otherwise be agreed by the Lender in writing. The Borrowers shall use the
proceeds of the Revolving Credit promptly.

                                       29
<PAGE>

                  2.3.3  Origination Fee.
                         ----------------

                  The Borrower shall pay to the Lender on or before the Closing
Date a loan origination fee (the "Origination Fee") in the amount of Two Hundred
Twenty Five Thousand Dollars ($225,000), which fee has been fully earned and is
non-refundable, One Hundred Seventy Five Thousand Dollars ($175,000) of which
has been paid prior to the Closing Date.

                  2.3.4  Administration and Audit Fees.
                         ------------------------------

                  The Borrower shall pay to the Lender an annual Administration
and Audit fee in the amount of Forty Thousand Dollars ($40,000) per annum, plus
any and all reasonable out of pocket expenses and travel time incurred by the
Lender (collectively, the "Administration and Audit Fees" and individually a
"Administration and Audit Fee"), which Administration and Audit Fees shall be
payable monthly in arrears on the first Business Day of each month commencing on
the first such date following the Closing Date, and continuing until the last
such date prior to which all Obligations arising out of, or under, the Credit
Facilities then outstanding have been paid in full.

                  2.3.5  Computation of Interest and Fees.
                         ---------------------------------

                  All applicable Fees and interest shall be calculated on the
basis of a year of 360 days for the actual number of days elapsed. Any change in
the interest rate on any of the Obligations resulting from a change in the Prime
Rate shall become effective as of the opening of business on the day on which
such change in the Prime Rate is announced.

                  2.3.6  Maximum Interest Rate.
                         ----------------------

                  In no event shall any interest rate provided for hereunder
exceed the maximum rate permissible for corporate borrowers under applicable law
for loans of the type provided for hereunder (the "Maximum Rate"). If, in any
month, any interest rate, absent such limitation, would have exceeded the
Maximum Rate, then the interest rate for that month shall be the Maximum Rate,
and, if in future months, that interest rate would otherwise be less than the
Maximum Rate, then that interest rate shall remain at the Maximum Rate until
such time as the amount of interest paid hereunder equals the amount of interest
which would have been paid if the same had not been limited by the Maximum Rate.
In the event that, upon payment in full of the Obligations, the total amount of
interest paid or accrued under the terms of this Agreement is less than the
total amount of interest which would, but for this Section, have been paid or
accrued if the interest rates otherwise set forth in this Agreement had at all
times been in effect, then the Borrowers shall, to the extent permitted by
applicable law, pay the Lender, an amount equal to the excess of (a) the lesser
of (i) the amount of interest which would have been charged if the Maximum Rate
had, at all times, been in effect or (ii) the amount of interest which would
have accrued had the interest rates otherwise set forth in this Agreement, at
all times, been in effect over (b) the amount of interest actually paid or
accrued under this Agreement. In the event that a court determines that the
Lender has received interest and other charges hereunder in excess of the
Maximum Rate, such excess shall be deemed received on account of, and shall
automatically be applied to reduce, the Obligations other than interest, in the
inverse order of maturity, and if there are no Obligations outstanding, the
Lender shall refund to the Borrowers such excess.

                  2.3.7  Payments.
                         ---------

                  All payments of the Obligations, including, without
limitation, principal, interest, Prepayments, and Fees, shall be paid by the
Borrowers without setoff or counterclaim to the Lender (except as otherwise
provided herein) at the Lender's office specified in Section 8.1 (Notices) in
immediately available funds not later than noon (Eastern Standard Time) on the
due date of such payment. All payments received by the Lender after such time
shall be deemed to have been received by the Lender for purposes of computing
interest and Fees and otherwise as of the next Business Day. Payments shall not
be considered received by the Lender until such payments are paid to the Lender
in immediately available funds.

                  2.3.8  Liens; Setoff.
                         --------------

                  The Borrowers hereby grant to the Lender a continuing Lien for
all of the Obligations upon any and all monies, securities, and other property
of the Borrowers and the proceeds thereof, now or hereafter held or received by
or in transit to, the Lender, and/or any Affiliate of the Lender, from or for
the Borrowers, and also upon any and all deposit accounts (general or special)
and credits of the Borrowers, if any, with the Lender or any Affiliate of the
Lender, at any time existing, excluding any deposit accounts held by the
Borrowers in their capacity as trustee for Persons who are not Borrowers or
Affiliates of the Borrowers. Without implying any limitation on any other rights
the Lender may have under the Financing Documents or applicable Laws, during the
continuance of an Event of Default, the Lender is hereby authorized by the
Borrowers at any time and from time to time, without notice to the Borrowers, to
set off, appropriate and apply any or all items hereinabove referred to against
all Obligations then outstanding (whether or not then due), all in such order
and manner as shall be determined by the Lender in its sole and absolute
discretion.

                  2.3.9  Requirements of Law.
                         --------------------

                  In the event that the Lender shall have determined in good
faith that (a) the adoption of any Capital Adequacy Regulation, or (b) any
change in any Capital Adequacy Regulation or application thereof or (c)
compliance by the Lender or any corporation controlling the Lender with any
request or directive regarding capital adequacy (whether or not having the force
of law) from any central bank or Governmental Authority, does or shall have the
effect of reducing the rate of return on the capital of the Lender or any
corporation controlling the Lender, as a consequence of the obligations of the
Lender hereunder to a level below that which the Lender or any corporation
controlling the Lender would have achieved but for such adoption, change or
compliance (taking into consideration the policies of the Lender and the
corporation controlling the Lender, with respect to capital adequacy) by an
amount deemed by the Lender to be material, then from time to time, after
submission by the Lender to the Borrowers of a written request therefor and a
statement of the basis for such determination, the Borrowers shall pay to the
Lender such additional amount or amounts in order to compensate for such
reduction. However, no such amount shall be payable in respect of any such
adoption, change or compliance occurring more than ninety (90) days before the
request from the Lender and a similar request for similar payments shall have
been made by the Lender to other borrowers having offices in the United States.

                  2.3.10 Funds Transfer Services.
                         ------------------------

                         (a)  The Borrowers have requested that the Lender and
its Affiliates make available to the Borrowers electronic funds transfer
services and related security measures in connection with the Obligations. A
copy of the Lender's current Wire Transfer Procedures, including the Security
Procedures, is attached to this Agreement as EXHIBIT C. Each Borrower
                                             ---------
acknowledges and agrees that all electronic funds transfers made by the Lender
or any Affiliate of the Lender to, or for the account of, any Borrower shall be
governed by, and subject to, the Wire Transfer Procedures and the Security
Procedures in effect from time to time. The Borrowers and the Lender agree that
the current Wire Transfer Procedures and the Security Procedures are
commercially reasonable. Each Borrower further acknowledges and agrees, however,
that the full scope of the Security Procedures which the Lender and its
Affiliates offer and strongly recommend for electronic funds transfers is
available only if the Company communicates directly with the Lender or its
Affiliate, as applicable, in accordance with and as required by the Wire
Transfer Procedures and the Security Procedures. If the Company or any Borrower
attempts to communicate with the Lender or any Affiliate of the Lender by any
other method or otherwise does not communicate with the Lender and/or its
Affiliate, as appropriate, in accordance with the Wire Transfer Procedures and
the Security Procedures, the Lender and/or its Affiliate, as applicable, shall
not be required to execute the instructions of the Company or any such Borrower,
but if the Lender or such Affiliate, as applicable, does so, the Borrowers will
be deemed to have refused and waived the Security Procedures that the Lender or
its Affiliate, as applicable, offers and strongly recommends, and the Borrowers
will be bound by any funds transfer, whether or not authorized, which is issued
in any Borrower's name and accepted by the Lender or any Affiliate, as
applicable, in good faith. The Lender or its Affiliate, as applicable, may
modify the Wire Transfer Procedures including, without limitation, the Security
Procedures at such time or times and in such manner as the Lender and/or any
Affiliate of the Lender, as applicable, in its or their sole and absolute
discretion, deems appropriate to meet then prevailing standards of good banking
practice. The Lender shall notify the Company of any material change or
modification to the Wire Transfer Procedures and/or the Security Procedures. By
continuing to use the wire transfer services of the Lender and/or any Affiliate
of the Lender following notice to the Company of any such change or modification
to the Wire Transfer Procedures and/or the Security Procedures, the Borrowers
shall be deemed automatically to have agreed to the Wire Transfer Procedures and
the Security Procedures, as changed and/or modified and to have further agreed
that the Wire Transfer Procedures and the Security Procedures, as changed and/or
modified, are likewise commercially reasonable. The Borrowers further agree to
establish and maintain procedures to safeguard the Security Procedures and any
information related thereto. Neither the Lender nor any Affiliate of the Lender
is responsible for detecting any error in any payment order sent by the Company
to the Lender or any Affiliate of the Lender.

                         (b)  The Lend and its Affiliates, as applicable, will
generally use the Fedwire funds transfer system for domestic funds transfers,
and the funds transfer system operated by the Society for Worldwide
International Financial Telecommunication (SWIFT) for international funds
transfers. International funds transfers may also be initiated through the
Clearing House InterBank Payment System (CHIPs) or international cable. However,
the Lender and/or its Affiliates, as applicable, may use any means and routes
that the Lender or any such Affiliate, as applicable, in its sole discretion,
may consider suitable for the transmission of funds.

                                       32
<PAGE>

Each payment order, or cancellation thereof, carried out through a funds
transfer system or a clearinghouse will be governed by all applicable funds
transfer system rules and clearing house rules and clearing arrangements,
whether or not the Lender or any Affiliate, as applicable, is a member of the
system, clearinghouse or arrangement and the Borrower acknowledges that the
right of the Lender or any Affiliate, as applicable, to reverse, adjust, stop
payment or delay posting of an executed payment order is subject to the Laws,
regulations, rules, circulars and arrangements described herein.

                  2.3.11 ACH Transactions.
                         -----------------

                  The Company may request and the Lender or its Affiliates may,
in their sole and absolute discretion, provide ACH Transactions although the
Company is not required to do so. In the event the Company requests Lender or
its Affiliates to procure ACH Transactions, then the Borrowers agrees to jointly
and severally indemnify and hold the Lender or its Affiliates harmless from any
and all obligations now or hereafter owing to the Lender or its Affiliates in
connection with such ACH Transactions. The Borrowers agree to pay the Lender or
its Affiliates all amounts owing to the Lender or its Affiliates pursuant to ACH
Transactions. In the event the Borrowers shall not have paid to the Lender or
its Affiliates such amounts, the Lender may cover such amounts by an advance
under the Revolving Credit, which advance shall be deemed to have been requested
by the Borrowers. The Borrowers acknowledge and agree that the obtaining of ACH
Transactions from the Lender or its Affiliates (a) is in the sole and absolute
discretion of the Lender or its Affiliates and (b) is subject to all rules and
regulations of the Lender or its Affiliates.

                  2.3.12 Guaranty.
                         ---------

                         (a)  Each Borrower hereby unconditionally and
irrevocably, guarantees to the Lender:

                              (i)    the due and punctual payment in full (and
          not merely the collectibility) by the other Borrowers of the
          Obligations, including unpaid and accrued interest thereon, in each
          case when due and payable, all according to the terms of this
          Agreement, the Notes and the other Financing Documents;

                              (ii)   the due and punctual payment in full (and
          not merely the collectibility) by the other Borrowers of all other
          sums and charges which may at any time be due and payable in
          accordance with this Agreement, the Notes or any of the other
          Financing Documents;

                              (iii)  the due and punctual performance by the
          other Borrowers of all of the other terms, covenants and conditions
          contained in the Financing Documents; and

                              (iv)   all the other Obligations of the other
          Borrowers.

                                       33
<PAGE>

                  (b)    The obligations and liabilities of each Borrower as a
guarantor under this Section 2.3.12 shall be absolute and unconditional and
joint and several, irrespective of the genuineness, validity, priority,
regularity or enforceability of this Agreement, any of the Notes or any of the
Financing Documents or any other circumstance which might otherwise constitute a
legal or equitable discharge of a surety or guarantor. Each Borrower in its
capacity as a guarantor expressly agrees that the Lender may, in its sole and
absolute discretion, without notice to or further assent of such Borrower and
without in any way releasing, affecting or in any way impairing the joint and
several obligations and liabilities of such Borrower as a guarantor hereunder:

                         (i)    waive compliance with, or any defaults under, or
          grant any other indulgences under or with respect to any of the
          Financing Documents;

                         (ii)   modify, amend, change or terminate any
          provisions of any of the Financing Documents;

                         (iii)  grant extensions or renewals of or with respect
          to the Credit Facilities, the Notes or any of the other Financing
          Documents;

                         (iv)   effect any release, subordination, compromise or
          settlement in connection with this Agreement, any of the Notes or any
          of the other Financing Documents;

                         (v)    agree to the substitution, exchange, release or
          other disposition of the Collateral or any part thereof, or any other
          collateral for the Revolving Credit or to the subordination of any
          lien or security interest therein;

                         (vi)   make advances for the purpose of performing any
          term, provision or covenant contained in this Agreement, any of the
          Notes or any of the other Financing Documents with respect to which
          the Borrowers shall then be in default;

                         (vii)  make future advances pursuant to the Financing
          Agreement or any of the other Financing Documents;

                         (viii) assign, pledge, hypothecate or otherwise
          transfer the Revolving Credit Commitment, the Obligations, the Notes,
          any of the other Financing Documents or any interest therein, all as
          and to the extent permitted by the provisions of this Agreement;

                         (ix)   deal in all respects with the other Borrowers as
          if this Section 2.3.12 were not in effect;

                                       34
<PAGE>

                         (x)    effect any release, compromise or settlement
          with any of the other Borrowers, whether in their capacity as a
          Borrower or as a guarantor under this Section 2.3.12, or any other
          guarantor; and

                         (xi)   provide debtor-in-possession financing or allow
          use of cash collateral in proceedings under the Bankruptcy Code, it
          being expressly agreed by all Borrowers that any such financing and/or
          use would be part of the Obligations.

                    (c)  The obligations and liabilities of each Borrower, as
guarantor under this Section 2.3.12, shall be primary, direct and immediate,
shall not be subject to any counterclaim, recoupment, set off, reduction or
defense based upon any claim that a Borrower may have against any one or more of
the other Borrowers, the Lender, and/or any other guarantor and shall not be
conditional or contingent upon pursuit or enforcement by the Lender of any
remedies it may have against the Borrowers with respect to this Agreement, the
Notes or any of the other Financing Documents, whether pursuant to the terms
thereof or by operation of law. Without limiting the generality of the
foregoing, the Lender shall not be required to make any demand upon any of the
Borrowers, or to sell the Collateral or otherwise pursue, enforce or exhaust its
remedies against the Borrowers or the Collateral either before, concurrently
with or after pursuing or enforcing its rights and remedies hereunder. Any one
or more successive or concurrent actions or proceedings may be brought against
each Borrower under this Section 2.3.12, either in the same action, if any,
brought against any one or more of the Borrowers or in separate actions or
proceedings, as often as the Lender may deem expedient or advisable. Without
limiting the foregoing, it is specifically understood that any modification,
limitation or discharge of any of the liabilities or obligations of any one or
more of the Borrowers, any other guarantor or any obligor under any of the
Financing Documents, arising out of, or by virtue of, any bankruptcy,
arrangement, reorganization or similar proceeding for relief of debtors under
federal or state law initiated by or against any one or more of the Borrowers,
in their respective capacities as borrowers and guarantors under this Section
2.3.12, or under any of the Financing Documents shall not modify, limit, lessen,
reduce, impair, discharge, or otherwise affect the liability of each Borrower
under this Section 2.3.12 in any manner whatsoever, and this Section 2.3.12
shall remain and continue in full force and effect. It is the intent and purpose
of this Section 2.3.12 that each Borrower shall and does hereby waive all rights
and benefits which might accrue to any other guarantor by reason of any such
proceeding, and the Borrowers agree that they shall be liable for the full
amount of the obligations and liabilities under this Section 2.3.12, regardless
of, and irrespective to, any modification, limitation or discharge of the
liability of any one or more of the Borrowers, any other guarantor or any
obligor under any of the Financing Documents, that may result from any such
proceedings.

                    (d)  Each Borrower, as guarantor under this Section 2.3.12,
hereby unconditionally, jointly and severally, irrevocably and expressly waives:

                         (i)    presentment and demand for payment of the
          Obligations and protest of non-payment;

                         (ii)   notice of acceptance of this Section 2.3.12 and
          of presentment, demand and protest thereof;

                                       35
<PAGE>

                              (iii)  notice of any default hereunder or under
          the Notes or any of the other Financing Documents and notice of all
          indulgences;

                              (iv)   notice of any increase in the amount of any
          portion of or all of the indebtedness guaranteed by this Section
          2.3.12;

                              (v)    demand for observance, performance or
          enforcement of any of the terms or provisions of this Section 2.3.12,
          the Notes or any of the other Financing Documents;

                              (vi)   all errors and omissions in connection with
          the Lender's administration of all indebtedness guaranteed by this
          Section 2.3.12, except errors and omissions resulting from the
          Lender's acts of willful misconduct or gross negligence;

                              (vii)  any right or claim of right to cause a
          marshalling of the assets of any one or more of the other Borrowers;

                              (viii) any act or omission of the Lender which
          changes the scope of the risk as guarantor hereunder; and

                              (ix)   all other notices and demands otherwise
          required by law which the Borrower may lawfully waive.

                         (a)  Each advance under the Revolving Credit shall bear

specified by the Borrowers in an Interest Rate Election Notice furnished to the
Lender in accordance with the provisions of Section 2.4.2(e), or as otherwise
determined in accordance with the provisions of this Section 2.4.

                         (b)  Notwithstanding the foregoing, following the
occurrence and during the continuance of an Event of Default, at the option of
the Lender, all advances under the Revolving Credit and all other Obligations
shall bear interest at the Post-Default Rate.

                         (c)  The Applicable Margin for (i) Eurodollar Loans
shall be 300 basis points per annum, and (ii) Base Rate Loans shall be zero (0)
basis points per annum.

                  2.4.2  Selection of Interest Rates.
                         ----------------------------

                         (a)  The Borrowers, through the Company, may select the
initial Applicable Interest Rate or Applicable Interest Rates to be charged on
the advances of the Revolving Credit.

<PAGE>

                         (b)  From time to time after the date of this Agreement
as provided in this Section, by a proper and timely Interest Rate Election
Notice furnished to the Lender in accordance with the provisions of Section
2.4.2(e), the Company may select an initial Applicable Interest Rate or
Applicable Interest Rates for any advances on the Revolving Credit or may
convert the Applicable Interest Rate and, when applicable, the Interest Period,
for any existing advance on the Revolving Credit to any other Applicable
Interest Rate or, when applicable, any other Interest Period.

                         (c)  The Company's selection of an Applicable Interest
Rate and/or an Interest Period, the Company's election to convert an Applicable
Interest Rate and/or an Interest Period to another Applicable Interest Rate or
Interest Period, and any other adjustments in an interest rate are subject to
the following limitations:

                              (i)    the Company shall not at any time select or
          change to an Interest Period that extends beyond the Revolving Credit
          Expiration Date;

                              (ii)   except as otherwise provided in Section
          2.4.4 (Indemnity), no change from the Eurodollar Rate to the Base Rate
          shall become effective on a day other than a Business Day and on a day
          which is the last day of the then current Interest Period, no change
          of an Interest Period shall become effective on a day other than the
          last day of the then current Interest Period, and no change from the
          Base Rate to the Eurodollar Rate shall become effective on a day other
          than a day which is a Eurodollar Business Day;

                              (iii)  any Applicable Interest Rate change for any
          advance under the Revolving Credit to be effective on a date on which
          any principal payment on account of such advance is scheduled to be
          paid shall be made only after such payment shall have been made;

                              (iv)   no more than five (5) different Eurodollar
          Rates may be outstanding at any time and from time to time with
          respect to the advance;

                              (v)    the first day of each Interest Period shall
          be a Eurodollar Business Day;

                              (vi)   as of the effective date of a selection,
          there shall not exist an Event of Default; and

                              (vii)  the minimum principal amount of a
          Eurodollar Loan shall be One Million Dollars ($1,000,000).

                         (d)  If a request for an advance under the Revolving
Credit is not accompanied by an Interest Rate Election Notice or does not
otherwise include a selection of an Applicable Interest Rate and, if applicable,
an Interest Period, or if, after having made a

                                       37
<PAGE>

selection of an Applicable Interest Rate and, if applicable, an Interest Period,
the Borrowers fail or are not otherwise entitled under the provisions of this
Agreement to continue such Applicable Interest Rate or Interest Period, the
Borrowers shall be deemed to have selected the Base Rate as the Applicable
Interest Rate until such time as the Company has selected a different Applicable
Interest Rate and specified an Interest Period in accordance with, and subject
to, the provisions of this Section.

                         (e)  The Lender will not be obligated to make advances
on the Revolving Credit, to convert the Applicable Interest Rate on advances to
another Applicable Interest Rate, or to change Interest Periods, unless the
Lender shall have received an irrevocable written or telephonic notice (an
"Interest Rate Election Notice") from the Company specifying the following
information:

                              (i)    the amount to be borrowed or converted;

                              (ii)   a selection of the Base Rate or the
          Eurodollar Rate;

                              (iii)  the length of the Interest Period if the
          Applicable Interest Rate selected is the Eurodollar Rate; and

                              (iv)   the requested date on which such election
          is to be effective.

                  Any telephonic notice must be confirmed in writing within
three (3) Business Days. Each Interest Rate Election Notice must be received by
the Lender not later than 12:00 noon (Eastern Standard Time) on the Business Day
of any requested borrowing or conversion in the case of a selection of the Base
Rate and not later than 12:00 noon (Eastern Standard Time) on the third Business
Day before the effective date of any requested borrowing or conversion in the
case of a selection of the Eurodollar Rate.

                  2.4.3  Inability to Determine Eurodollar Base Rate.
                         --------------------------------------------

                  In the event that (a) the Lender shall have determined that,
by reason of circumstances affecting the London interbank eurodollar market,
adequate and reasonable means do not exist for ascertaining the Eurodollar Base
Rate for any requested Interest Period with respect to an advance the Borrowers
have requested to be made as or to be converted to a Eurodollar Loan or (b) the
Lender shall determine that the Eurodollar Base Rate for any requested Interest
Period with respect to an advance the Company has requested to be made as or to
be converted to a Eurodollar Loan does not adequately and fairly reflect the
cost to the Lender of funding or converting such Loan, the Lender shall give
telephonic or written notice of such determination to the Company at least one
(1) day prior to the proposed date for funding or converting such advance. If
such notice is given, any request for a Eurodollar Loan shall be made as or
converted to a Base Rate Loan. Until such notice has been withdrawn by the
Lender, the Company will not request that any advance under the Revolving Credit
be made as or converted to a Eurodollar Loan. Any such notice must be withdrawn
promptly following the cessation of the circumstances that caused such notice to
be given.

                  2.4.4  Indemnity.
                         ----------

                  The Borrowers jointly and severally agree to indemnify and
reimburse the Lender and to hold the Lender harmless from any loss, cost
(including administrative costs) or expense which the Lender may sustain or
incur as a consequence of (a) a default by the Borrowers in payment when due of
the principal amount of or interest on any Eurodollar Loan, (b) the failure of
the Borrowers to make, or convert the Applicable Interest Rate of, an advance to
or at a Eurodollar Rate after the Borrowers have given a Loan Notice or an
Interest Rate Election Notice as of the date specified in such Notice and/or (c)
the making by the Borrowers of a prepayment of a Eurodollar Loan on a day which
is not the last day of the Interest Period for such Eurodollar Loan, calculated
as provided in the following section. This agreement and covenant of the
Borrowers shall survive termination or expiration of this Agreement and payment
of the other Obligations.

                  Contemporaneously with any prepayment of principal of a
Eurodollar Loan on a day that is not the last day for the Interest Period for
such Eurodollar Loan, a prepayment fee shall be due and payable to the Lender in
an amount equal to the product of
                       -------

     (A)  the amount so prepaid

     multiplied by
     -------------

     (B)  the difference (but not less than zero) of
          --------------

          (i)  the constant maturity 360-day interest yield (as of the first day
          of the then effective Interest Period and expressed as a decimal) for
          a United States Treasury bill, note, or bond (a "Treasury obligation")
          selected by the Lender, in an aggregate amount comparable to the
          amount prepaid, and having, as of the first day of the then effective
          Interest Period, a remaining term approximately equal to the original
          Interest Period,

     minus
     -----

          (ii) the 360-day interest yield (as of the Business Day immediately
          preceding the prepayment date and expressed as a decimal) on such
          Treasury obligation and having, as of the Business Day immediately
          preceding the prepayment date, a remaining term until maturity
          approximately equal to the unexpired portion of the Interest Period,

     multiplied by
     -------------

               The applicable yields on the Treasury obligations described above
shall be determined based upon the Federal Reserve statistical release H.15
published for the applicable determination dates set forth above.  Any Treasury
obligation selected when the related Interest Period is one year or less shall
be United States Treasury Bills.  The Lender shall not be obligated or required
to have actually reinvested the prepaid amount of the Eurodollar Loan in any
such Treasury obligation as a condition precedent to the Borrowers being
obligated to pay a prepayment fee as outlined above.  The Lender shall not be
obligated to accept any prepayment of principal unless it is accompanied by the
prepayment fee, if any, due in connection therewith as calculated pursuant to
the provisions of this paragraph.  No prepayment fee payable in connection
herewith shall in any event or under any circumstances be deemed or construed as
a penalty.

Revolving Credit which consists of a Base Rate Loan shall be paid monthly, in
arrears, on the first day of each calendar month, commencing on the first such
date after the date of this Agreement, and on the first day of each calendar
month thereafter, and at maturity (whether by acceleration, declaration,
extension or otherwise).

                      (b) Notwithstanding the foregoing, any and all unpaid and
accrued interest on any Base Rate Loan converted to a Eurodollar Loan or prepaid
shall be paid immediately upon such conversion and/or prepayment, as
appropriate.

                      (c) Unpaid and accrued interest on any Eurodollar Loan
shall be paid monthly and on the last Business Day of each Interest Period for
such Eurodollar Loan and at maturity (whether by acceleration, declaration,
extension or otherwise); provided, however that any and all unpaid and accrued
interest on any Eurodollar Loan prepaid prior to expiration of the then current
Interest Period for such Eurodollar Loan shall be paid immediately upon
prepayment.

organized, existing and in good standing under the laws of the jurisdiction of
its incorporation, (b) has the corporate power to own its property and to carry

Borrower's charter, bylaws, operating agreement or articles of organization, as
the case may be, (b) any existing mortgage, indenture, contract or agreement
binding on any Borrower or affecting its property, or (c) any Laws.

                  4.1.6  No Defaults, Violations.
                         ------------------------

is in violation of any applicable Laws (including, without limitation, any Laws
relating to employment practices, to environmental, occupational and health
standards and controls) or order, writ, injunction, decree or demand of any
court, arbitrator, or any Governmental Authority affecting any Borrower or any

                  4.1.8  Margin Stock.
                         -------------

                  None of the proceeds of the Revolving Credit will be used,
directly or indirectly, by any Borrower or any Subsidiary for the purpose of
purchasing or carrying, or for the purpose of reducing or retiring any
indebtedness which was originally incurred to purchase or

                                       43
<PAGE>

carry, any "margin stock" within the meaning of Regulation U (12 CFR Part 221),
of the Board of Governors of the Federal Reserve System or for any other purpose
which might make the transactions contemplated in this Agreement a "purpose
credit" within the meaning of Regulation U, or cause this Agreement to violate
any other regulation of the Board of Governors of the Federal Reserve System or
the Securities Exchange Act of 1934 or the Small Business Investment Act of

                       -----------

               Except as otherwise disclosed on Schedule 4.1.10 attached hereto
                                                ---------------
and made a part hereof, there are no proceedings, actions or investigations
pending or, so far as any Borrower knows, threatened before or by any court,
arbitrator or any Governmental Authority which, in any one case or in the
aggregate, if determined adversely to the interests of any Borrower or any
Subsidiary, would have a Material Adverse Effect.

               4.1.11  Financial Condition.
                       --------------------

               The consolidated financial statements of the Borrowers dated May
31, 2000, are complete and correct and fairly present the financial position of
each of the Borrowers and its Subsidiaries and the results of their operations
and transactions in their surplus accounts as of the date and for the period
referred to therein and have been prepared in accordance with GAAP applied on a
consistent basis throughout the period involved. There are no liabilities,
direct or indirect, fixed or contingent, of any Borrower or any Subsidiary as of
the date of such financial statements that are not reflected therein or in the
notes thereto. To the best of each Borrower's knowledge, there has been no
material adverse change in the financial condition or operations of any Borrower
or any Subsidiary since the date of such financial statements and to the best of
such Borrowers' knowledge no such adverse change is pending. None of the
Borrowers nor any Subsidiary has guaranteed the obligations of, or made any

Agreement or as disclosed in the most recent financial statements delivered by
the Company to the Lender.

               4.1.12  Full Disclosure.
                       ----------------

               The financial statements referred to in Section 4.1.11 (Financial
Condition) of this Agreement, the Financing Documents (including, without
limitation, this Agreement), and the statements, reports or certificates
furnished by any Borrower in connection with the Financing Documents (a) do not
contain any untrue statement of a material fact and (b)

                                       44
<PAGE>

when taken in their entirety, do not omit any material fact necessary to make
the statements contained therein not misleading. There is no fact known to any
Borrower which such Borrower has not disclosed to the Lender in writing prior to
the date of this Agreement with respect to the transactions contemplated by the
Financing Documents which constitutes or could constitute a Material Adverse
Effect.

               4.1.13  Indebtedness for Borrowed Money.
                       --------------------------------

               Except for the Obligations and except as set forth in Schedule
                                                                     --------

---------------
agreements, documents, or instruments securing, evidencing, guarantying or
otherwise executed and delivered in connection therewith.

               4.1.14  Convertible Debt.
                       -----------------

               None of the Convertible Debt Loan Documents has been amended,
supplemented, restated or otherwise modified except as otherwise disclosed to
the Lender in writing on or before the effective date of any such amendment,
supplement, restatement or other modification.  In addition, there does not
exist any default or any event which upon notice or lapse of time or both would
constitute a default under the terms of any of the Convertible Debt Loan
Documents.

               4.1.15  Taxes.
                       ------

               Each of the Borrowers and its Subsidiaries has filed all returns,
reports and forms for Taxes which, to the knowledge of the Borrowers, are
required to be filed, and has paid all Taxes as shown on such returns or on any
assessment received by it, to the extent that such Taxes have become due, unless
and to the extent only that such Taxes, assessments and governmental charges are
currently contested in good faith and by appropriate proceedings by a Borrower,
such Taxes are not the subject of any Liens other than Permitted Liens, and
adequate reserves therefor have been established as required under GAAP.  All
tax liabilities of the Borrowers were as of the date of audited financial
statements referred to in Section 4.1.11 (Financial Condition), and are now,
adequately provided for on the books of the Borrowers and its Subsidiaries, as
appropriate.  To the best of each Borrower's knowledge, no tax liability has
been asserted by the Internal Revenue Service or any state or local authority
against any Borrower for Taxes in excess of those already paid.

               4.1.16  ERISA.
                       ------

               With respect to any Plan that is maintained or contributed to by
any Borrower and/or by any Commonly Controlled Entity or as to which any of the
Borrowers retains material liability: (a) no "accumulated funding deficiency" as
defined in Code (S)412 or ERISA (S)302 has occurred, whether or not that
accumulated funding deficiency has been waived; (b) no Reportable Event has
occurred other than events for which reporting has been waived or that are
unlikely to result in material liability for any of the Borrowers; (c) no
termination of any plan subject to Title IV of ERISA has occurred; (d) neither
any Borrower nor any Commonly Controlled Entity has incurred a "complete
withdrawal" within the meaning of ERISA (S)4203

                                       45
<PAGE>

from any Multi-employer Plan that is likely to result in material liability for
one or more of the Borrowers; (e) neither any Borrower nor any Commonly
Controlled Entity has incurred a "partial withdrawal" within the meaning of
ERISA (S)4205 with respect to any Multi-employer Plan that is likely to result
in material liability for one or more of the Borrowers; (f) no Multi-employer
Plan to which any Borrower or any Commonly Controlled Entity has an obligation
to contribute is to the knowledge of the Borrowers, in "reorganization" within
the meaning of ERISA (S)4241 nor has notice been received by any Borrower or any
Commonly Controlled Entity that such a Multi-employer Plan will be placed in
"reorganization."

          4.1.17  Title to Properties.
                  --------------------

          The Borrowers have good and marketable title to all of their
respective properties, including, without limitation, the Collateral and the
properties and assets reflected in the balance sheets described in Section
4.1.11 (Financial Condition).  The Borrowers have legal, enforceable and
uncontested rights to use freely such property and assets.  All of such
properties, including, without limitation, the Collateral which were purchased,
were in each Borrower's good faith belief purchased for fair consideration and
reasonably equivalent value in the ordinary course of business of both the
seller and the Borrowers and not, by way of example only, as part of a bulk
sale.

          4.1.18  Patents, Trademarks, Etc.
                  -------------------------

          Each of the Borrowers and its Subsidiaries owns, possesses, or has the
right to use all patents, licenses, trademarks, copyrights, permits and
franchises necessary to conduct its business as now conducted, without known
conflict with the rights of any other Person.  Any and all obligations to pay
royalties or other charges with respect to such properties and assets are
properly reflected on the financial statements described in Section 4.1.11
(Financial Condition).

          4.1.19  Employee Relations.
                  -------------------

          Except as disclosed on Schedule 4.1.19 attached hereto and made a part
                                 ---------------
hereof, (a) no Borrower nor any Subsidiary thereof nor any of the Borrower's or
Subsidiary's employees is subject to any collective bargaining agreement, (b) no
petition for certification or union election is pending with respect to the
employees of any Borrower or any Subsidiary and no union or collective
bargaining unit has sought such certification or recognition with respect to the
employees of a Borrower, (c) there are no strikes, slowdowns, work stoppages or
controversies pending or, to the best knowledge of the Borrowers after due
inquiry, threatened between any Borrower and its employees, and (d) no Borrower
nor any Subsidiary is subject to an employment contract, severance agreement,
commission contract or bonus agreement.  Hours worked and payments made to the
employees of any one or more of the Borrowers have not been in violation of the
Fair Labor Standards Act or any other applicable law dealing with such matters.
All payments due from any one or more of the Borrowers or for which any claim
may be made against a Borrower, on account of wages and employee and retiree
health and welfare insurance and other benefits have been paid or accrued as a
liability on its books.  The consummation of the transactions contemplated by
the Financing Agreement or any of the other Financing Documents, will not give
rise to a right of termination or right of renegotiation on the

                                       46
<PAGE>

part of any union under any collective bargaining agreement to which any
Borrower is a party or by which it is bound.

                  ------------------------------------------------------
                  Contamination.
                  --------------

          Except as described on Schedule 4.1.20 and to the best of each
Borrower's knowledge, (a) no Hazardous Materials are located on any real
property owned, controlled or operated by any Borrower or for which any Borrower
is, or is claimed to be, responsible, except for reasonable quantities of
Hazardous Materials Used or generated by a Borrower in the ordinary course of
its business and stored, used and disposed in accordance with applicable Laws;
and (b) no property owned, controlled or operated by any Borrower or for which
any Borrower has, or is claimed to have, responsibility has ever been used as a
manufacturing, storage, disposal, or dump site for Hazardous Materials nor is
affected by Hazardous Materials Contamination at any other property.

          4.1.21  Perfection and Priority of Collateral.
                  --------------------------------------

          The Lender has, or upon execution and recording of this Agreement and
the Security Documents will have, and will continue to have as security for the
Obligations, a valid and perfected Lien on and security interest in all
Collateral, free of all other Liens, claims and rights of third parties
whatsoever except Permitted Liens, including, without limitation, those
described on Schedule 4.1.21 attached hereto and made a part hereof.
             ---------------

          4.1.22  Places of Business and Location of Collateral.
                  ----------------------------------------------

          The information contained in the Collateral Disclosure List is
complete and correct.  The Collateral Disclosure List completely and accurately
identifies the address of (a) the chief executive office of each Borrower, (b)
any and each other place of business of each Borrower, (c) the location of all
books and records pertaining to the Collateral, and (d) each location, other
than the foregoing, where any of the Collateral is located.  The proper and only
places to file financing statements with respect to the Collateral within the
meaning of the Uniform Commercial Code are the filing offices for those
jurisdictions in which any one or more of the Borrowers maintain a place of
business as identified on the Collateral Disclosure List.

          4.1.23  Business Names and Addresses.
                  -----------------------------

          In the five (5) years preceding the date hereof, no Borrower has
changed its name, identity or corporate structure, has conducted business under

Borrower, or (b) any Reportable Event if, upon termination of the plan or plans
with respect to which one or more such Reportable Events shall have occurred,

owned, operated or controlled by any Borrower for which any Borrower is, or is
claimed to be, responsible. Each Borrower acknowledges and agrees that this

entitled, and may accept, in connection therewith, the return of goods, the sale

and Inventory (but in any event sufficient to avoid any co-insurance
obligations) and with a specific endorsement to each such insurance policy
pursuant to which the insurer agrees to give the Lender at least thirty (30)
days written notice before any alteration or cancellation of such insurance
policy and that no act or default of any of the Borrowers shall affect the right
of the Lender to recover under such policy in the event of loss or damage; (b)

effect and stating the names of the insurance companies, the amounts and rates
of the insurance, dates of the expiration thereof and the properties and risks

their Subsidiaries and examine, audit and inspect the Collateral at any

Collateral (and any part thereof), and will immediately execute, acknowledge and
deliver any financing statement, renewal, affidavit, deed, assignment,
continuation statement, security agreement, certificate or other document which
the Lender may require in order to perfect, preserve, maintain, continue,
protect and/or extend the Lien or security interest granted to the Lender under

priority of that Lien, subject only to the Permitted Liens. The Borrowers will
from time to time do whatever the Lender may require by way of obtaining,
executing, delivering, and/or filing financing statements, landlords' or
mortgagees' waivers, notices of assignment and other notices and amendments and
renewals thereof and the Borrowers will take any and all steps and observe such
formalities as the Lender may require, in order to create and maintain a valid

of, a party other than the Borrowers or the Lender, the Borrowers shall cause
all such parties to execute and deliver on the Closing Date security documents,
financing statements or other documents as requested by the Lender and as may be
necessary to evidence and/or perfect the security interest of the Lender in
those proceeds. The Borrowers agree that a copy of a fully executed security
agreement and/or financing statement shall be sufficient to satisfy for all
purposes the requirements of a financing statement as set forth in Article 9 of
the applicable Uniform Commercial Code. Each Borrower hereby irrevocably
appoints the Lender as the Borrower's attorney-in-fact, with power of
substitution, in the name of the Lender or in the name of the Borrower or
otherwise, for the use and benefit of the Lender, but at the cost and expense of
the Borrowers and without notice to the Borrowers, to execute and deliver any
and all of the instruments and other documents and take any action which the
Lender may require pursuant the foregoing provisions of this Section 6.1.22.

business, (b) any change of the location of the chief executive office of the
applicable Borrower or Subsidiary, and (c) the opening of any new place of
business or the closing of any existing place of business, and any change in the
location of the places where the Collateral, or any part thereof, or the books
and records, or any part thereof, are kept (provided that, if any such change or
opening is pending within thirty (30) days at the time an Additional Borrower
becomes an Additional Borrower, such Additional Borrower will instead give such
notice to the Lender at that time).

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

                  In the event that any Borrower or any Subsidiary shall
transfer its principal place of business or the office where it keeps its
records pertaining to the Collateral, upon the Lender's request the Borrowers
will provide to the Lender a subsequent opinion of counsel as to

                                       62

                  ---------

time, at any time thereafter exercise any one or more of the following rights,
powers or remedies.

                  7.2.1  Acceleration.
                         -------------

                  The Lender may after oral notice to the Company, declare any
or all of the Obligations to be immediately due and payable, notwithstanding
anything contained in this Agreement or in any of the other Financing Documents
to the contrary, without presentment, demand, protest, notice of protest or of
dishonor, or other notice of any kind, all of which the Borrowers hereby waive.

                  7.2.2  Further Advances.
                         -----------------

                  The Lender may from time to time without notice to the
Borrowers suspend, terminate or limit any further advances, loans or other
extensions of credit under the Revolving Credit Commitment, under this Agreement
and/or under any of the other Financing Documents. Further, upon the occurrence
of an Event of Default or Default specified in Sections 7.1.6 (Receiver;

Commitment and any agreement in any of the Financing Documents to provide
additional credit shall immediately and automatically terminate and the unpaid
principal amount of the Notes (with accrued interest thereon) and all other
Obligations then outstanding, shall immediately become due and payable without
further action of any kind and without presentment, demand, protest or notice of
any kind, all of which are hereby expressly waived by the Borrowers.

                  7.2.3  Uniform Commercial Code.
                         ------------------------

                  The Lender shall have all of the rights and remedies of a
secured party under the applicable Uniform Commercial Code and other applicable
Laws. Upon demand by the Lender, the Borrowers shall assemble the Collateral and
make it available to the Lender, at a place designated by the Lender. The Lender
or its agents may without notice from time to time enter upon any Borrower's
premises to take possession of the Collateral, to remove it, to render it
unusable, to process it or otherwise prepare it for sale, or to sell or
otherwise dispose of it.

                  Any written notice of the sale, disposition or other intended
action by the Lender with respect to the Collateral which is sent by regular
mail, postage prepaid, to the Borrowers at the address set forth in Section 8.1
(Notices), or such other address of the Borrowers which may from time to time be
shown on the Lender's records, at least ten (10) days prior to such sale,
disposition or other action, shall constitute commercially reasonable notice to
the Borrowers. The Lender may alternatively or additionally give such notice in
any other commercially reasonable manner. Nothing in this Agreement shall
require the Lender to give any notice not required by applicable Laws.

                  If any consent, approval, or authorization of any state,
municipal or other Governmental Authority or of any other Person or of any
Person having any interest therein, should be necessary to effectuate any sale
or other disposition of the Collateral, the Borrowers

                                       73
<PAGE>

agree to execute all such applications and other instruments, and to take all
other action, as may be required in connection with securing any such consent,
approval or authorization.

                  The Borrowers recognize that the Lender may be unable to
effect a public sale of all or a part of the Collateral consisting of Securities
by reason of certain prohibitions contained in the Securities Act of 1933, as
amended, and other applicable Federal and state Laws. The Lender may, therefore,
in its discretion, take such steps as it may deem appropriate to comply with
such Laws and may, for example, at any sale of the Collateral consisting of
securities restrict the prospective bidders or purchasers as to their number,
nature of business and investment intention, including, without limitation, a
requirement that the Persons making such purchases represent and agree to the
satisfaction of the Lender that they are purchasing such securities for their
account, for investment, and not with a view to the distribution or resale of
any thereof. The Borrowers covenant and agree to do or cause to be done promptly
all such acts and things as the Lender may request from time to time and as may
be necessary to offer and/or sell the securities or any part thereof in a manner
which is valid and binding and in conformance with all applicable Laws. Upon any
such sale or disposition, the Lender shall have the right to deliver, assign and
transfer to the purchaser thereof the Collateral consisting of securities so
sold.

                  7.2.4  Specific Rights With Regard to Collateral.
                         ------------------------------------------

hereunder or as shall exist at law or in equity from time to time, the Lender

Borrowers, and each Borrower hereby irrevocably appoints the Lender as its
attorney-in-fact, with power of substitution, in the name of the Lender and/or
in the name of any or all of the Borrowers or otherwise, for the use and benefit
of the Lender, but at the cost and expense of the Borrowers and without notice

correspondence, invoices and documents, relating to or evidencing any of the
Collateral or without cost or expense to the Lender, make such use of any
Borrower's or any Subsidiary's place(s) of business as may be reasonably
necessary to administer, control and collect the Collateral;

                  (e)    repair, alter or supply goods if necessary to fulfill
in whole or in part the purchase order of any Account Debtor;

                  (f)    demand, collect, receipt for and give renewals,
extensions, discharges and releases of any of the Collateral;

                                       74
<PAGE>

                  (g)    institute and prosecute legal and equitable proceedings
to enforce collection of, or realize upon, any of the Collateral;

                  (h)    settle, renew, extend, compromise, compound, exchange
or adjust claims in respect of any of the Collateral or any legal proceedings
brought in respect thereof;

                  (i)    endorse or sign the name of any Borrower upon any items
of payment, certificates of title, instruments, securities, stock powers,
documents, documents of title, financing statements, assignments, notices or
other writing relating to or part of the Collateral and on any proof of claim in
bankruptcy against an Account Debtor;

                  (j)    notify the Post Office authorities to change the
address for the delivery of mail to the Borrowers to such address or Post Office
Box as the Lender may designate and receive and open all mail addressed to any
of the Borrowers; and

                  (k)    take any other action necessary or beneficial to
realize upon or dispose of the Collateral or to carry out the terms of this
Agreement.

                  7.2.5  Application of Proceeds.
                         ------------------------

                  Any proceeds of sale or other disposition of the Collateral
will be applied by the Lender to the payment of any and all Enforcement Costs,
and any balance of such proceeds will be applied to the Obligations in such
order and manner as the Lender may from time to time in its sole and absolute
discretion determine. If the sale or other disposition of the Collateral fails
to fully satisfy the Obligations, the Borrowers shall remain liable to the
Lender for any deficiency.

                  7.2.6  Performance by Lender.
                         ----------------------

                  If the Borrowers shall fail to pay the Obligations or
otherwise fail to perform, observe or comply with any of the conditions,
covenants, terms, stipulations or agreements contained in this Agreement or any
of the other Financing Documents, the Lender without notice to or demand upon
the Borrowers and without waiving or releasing any of the Obligations or any
Default or Event of Default, may (but shall be under no obligation to) at any
time thereafter make such payment or perform such act for the account and at the
expense of the Borrowers, and may enter upon the premises of the Borrowers for
that purpose and take all such action thereon as the Lender may consider
necessary or appropriate for such purpose and each of the Borrowers hereby
irrevocably appoints the Lender as its attorney-in-fact to do so, with power of
substitution, in the name of the Lender, in the name of any or all of the
Borrowers or otherwise, for the use and benefit of the Lender, but at the cost
and expense of the Borrowers and without notice to the Borrowers. All sums so
paid or advanced by the Lender together with interest thereon from the date of
payment, advance or incurring until paid in full at the Post-Default Rate and
all costs and expenses, shall be deemed part of the Enforcement Costs, shall be
paid by the Borrowers to the Lender on demand, and shall constitute and become a
part of the Obligations.

                  The Lender may from time to time proceed to protect or enforce
the rights of the Lender by an action or actions at law or in equity or by any
other appropriate proceeding, whether for the specific performance of any of the
covenants contained in this Agreement or in any of the other Financing
Documents, or for an injunction against the violation of any of the terms of
this Agreement or any of the other Financing Documents, or in aid of the
exercise or execution of any right, remedy or power granted in this Agreement,
the Financing Documents, and/or applicable Laws. The Lender is authorized to
offset and apply to all or any part of the Obligations all moneys, credits and
other property of any nature whatsoever of any or all of the Borrowers now or at
any time hereafter in the possession of, in transit to or from, under the

Financing Documents to which it is a party, (b) the Lender shall remain solely
responsible for the performance of its obligations under this Agreement and
under all of the other Financing Documents to which it is a party, and (c) the

                   Borrowers acknowledge and agree that the Financing Documents,

Borrowers irrevocably agree that such service (y) shall be deemed in every
respect effective service of process upon the Borrowers in any such suit, action
or proceeding, and (z) shall, to the fullest extent permitted by law, be taken
and held to be valid personal service upon the Borrowers. Nothing in this
Section shall affect the right of the Lender to serve process in any manner
otherwise permitted by law or limit the right of the Lender otherwise to bring
proceedings against the Borrowers in the courts of any jurisdiction or
jurisdictions.

instrument.

                   ---------

     The headings in this Agreement are included herein for convenience only,
shall not constitute a part of this Agreement for any other purpose, and shall
not be deemed to affect the meaning or construction of any of the provisions
hereof.

     Section 8.14  No Agency.
                   ----------

     Nothing herein contained shall be construed to constitute the Borrowers as
the agent of the Lender for any purpose whatsoever or to permit the Borrowers to
pledge any of the credit of the Lender.  The Lender shall not be responsible or
liable for any shortage, discrepancy, damage, loss or destruction of any part of

prior agreements pertaining to the matters addressed by

                                       80
<PAGE>

this Agreement but shall look solely to this Agreement for definition and

the signing of this Agreement and in the making of this waiver by independent
legal counsel, selected of their own free will, and that they have had the
opportunity to discuss this waiver with counsel.

negligence, mistake, act or omission of any accountant, examiner, agency or
attorney employed by the Lender in making examinations, investigations or
collections, or otherwise in perfecting, maintaining, protecting or realizing
upon any lien or security interest or any other interest in the Collateral or
other security for the Obligations.

     By inspecting the Collateral or any other properties of the Borrowers or by
accepting or approving anything required to be observed, performed or fulfilled
by the Borrowers or to be given to the Lender pursuant to this Agreement or any
of the other Financing Documents, the Lender shall not be deemed to have
warranted or represented the condition, sufficiency, legality, effectiveness or
legal effect of the same, and such acceptance or approval shall not constitute
any warranty or representation with respect thereto by the Lender.

     Section 8.19  Indemnification.
                   ---------------

     The Borrowers agrees to indemnify and hold harmless, Lender, the respective
parent and Affiliates of the Lender and the respective parent's and Affiliates'

with the transactions contemplated hereunder. Notwithstanding anything herein or
elsewhere to the contrary, the Borrowers shall not be obligated to indemnify or
hold harmless any Indemnified Party from any liability, loss or damage resulting
from the gross negligence, willful misconduct or unlawful actions of such
Indemnified Party. Any amount payable to the Lender under this Section will bear
interest at the Post- Default Rate from the due date until paid.

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

                                                                       ---------

                        BANK OF AMERICA BUSINESS CREDIT

                           WIRE TRANSFER PROCEDURES

     The transfer of funds by means of wire may be made by Bank of America
(lender) at the request of its customer (borrower).  Such wire transfers are
categorized by lender as either repetitive or non-repetitive.

     Repetitive:
     ----------

     Repetitive wire transfers may vary in amount, but are consistent in terms
of the payee, the location to which funds are wired, the bank name, account
number and the routing transit number.

     Either borrower or lender may initiate a repetitive wire transfer.  The
borrower may identify the repetitive nature of transfers and request they be
established as such via the "Repetitive Wire Transfer Authorization Form" (copy
attached).  Lender, after observing numerous transfers to the same recipient and
destination, may initiate the repetitive process by faxing or mailing the
"Repetitive Wire Authorization Form" to the borrower for completion and return.

     Although a first request for a repetitive wire transfer may be honored from
a faxed copy of the "Repetitive Wire Transfer Authorization Form", a copy of the
form containing an original signature must be received from the borrower.  All
transfer authorization forms must be approved by and contain the signature of a
person authorized by the borrower to advance funds from borrower's line of
credit with the lender.

     After receipt of the original "Repetitive Wire Transfer Authorization Form"
by the lender, subsequent wire transfers to the recipient named thereon may be
initiated by telephone request, provided the requesting party is identified by
the lender as a person authorized by borrower to advance funds from the
borrower's line of credit with lender.

     Non-Repetitive:
     --------------

     Non-Repetitive wire transfers are directed to recipients on a one-time or
infrequent basis or are directed to varied destinations.  Non-repetitive wire
transfers require that written notification be provided to lender by borrower,
showing payee, location, account number, routing transit number and name and
location of bank into which funds are to be transferred.  Such written
notification may be provided by means of a "Non-Repetitive Wire Transfer
Authorization Form" (copy attached).

     Required information may be faxed to lender in order to expedite the
transfer; however, a copy of the transfer authorization form with an original
signature(s) must be received by lender from borrower.  The transfer
authorization form must be approved by and contain the signature
<PAGE>

of a person authorized by the borrower to advance funds from borrower's line of
credit with the lender.

     For any non-repetitive wire transfer, Lender may, at its discretion,
perform a telephone verification with an authorized representative (the original
signer or another authorized representative) of borrower prior to initiating the
transfer.
