                              THE CREDIT FACILITIES

    Section 2.1 The Revolving Credit Facility.

                2.1.1 Revolving Credit Facility.

                Subject to and upon the provisions of this Agreement, the Lender
establishes a revolving credit facility in favor of the Borrowers. The aggregate
of all advances under the Revolving Credit Facility is sometimes referred to in
this Agreement collectively as the "Revolving Credit". The principal amount of
Five Million Dollars ($5,000,000) is the "Revolving Credit Committed Amount".

                During the Revolving Credit Commitment Period, the Lender agrees
to make advances under the Revolving Credit requested by the Company from time
to time provided that after giving effect to the Company's request, the sum of
(a) the outstanding principal balance of the Revolving Credit and (b) the Letter
of Credit Obligations would not exceed the lesser of (y) the Revolving Credit
Committed Amount, or (z) the then most current Borrowing Base.

                Unless sooner paid, the unpaid Revolving Loan, together with
interest accrued and unpaid thereon, and all other Obligations shall be due and
payable in full on the Revolving Credit Expiration Date.

                2.1.2 Procedure for Making Advances Under the Revolving Credit;
                      Lender Protection 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. Not later than 11:00 a.m. (Eastern 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 Loan, 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 Revolving Credit Committed Amount or the Borrowing Base; provided,
however, that the Lender agrees to give the Company two (2) Business Days prior
notice of any such

                                       25

<PAGE>

advances, other than advances for the purposes of covering debit balances in the
Revolving Loan Account, principal of, and/or interest on, any Loan, 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) eighty percent (80%) of the amount
of Eligible Receivables derived from Government Contracts, plus (b) eighty
percent (80%) 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 Borrowers, 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.

               At all times as any Obligations are outstanding under this
Agreement or under any of the Financing Documents, the Borrowers will furnish to
the Lender no less frequently than the tenth (10/th/) day of each month and at
such other times as may be requested by the Lender a report of the Borrowing
Base (each a "Borrowing Base Report"; collectively, the "Borrowing Base
Reports") in the form required from time to time by the Lender, appropriately

                                       26

<PAGE>

completed and duly signed. The Borrowers acknowledge that the Lender has no
obligation to make any advance of the Revolving Credit Facility until a current
Borrowing Base Certificate has been received and approved by the Lender and that
the failure to provide a Borrowing Base Certificate on a regular basis may
result in a delay in funding any requested advances to the Revolving Credit
Facility. The Borrowing Base Report shall be dated as of the last day of the
preceding month and shall contain a detailed aging schedule of all Receivables
by Account Debtor as of the date of the Borrowing Base Report, the amount and
payments on the Receivables, and the calculations of the Borrowing Base, all in
such detail, and accompanied by such 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; and (c) 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 deliver any of
such items to the Lender shall not affect, terminate, modify, or otherwise limit
the Liens of the Lender in the Collateral.

               2.1.5 Revolving Credit Note.

               The obligation of the Borrowers to pay the Revolving Credit, with
interest, shall be evidenced by a promissory note (as from time to time
extended, amended, restated, supplemented or otherwise modified, the "Revolving
Credit Note") substantially in the form of EXHIBIT B attached hereto and made a
part hereof, with appropriate insertions. The Revolving Credit Note shall be
dated as of the Closing Date, shall be payable to the order of the Lender at the
times provided in the Revolving Credit Note, and shall be in the principal
amount of the Revolving Credit Committed Amount. Each of the Borrowers
acknowledges and agrees that, if the outstanding principal balance of the
Revolving Credit outstanding from time to time exceeds the face amount of the
Revolving Credit Note, the excess shall bear interest at the Post-Default Rate
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
continuing contractual relationship of the parties hereto in accordance with the
provisions of this Agreement.

               2.1.6 Mandatory Prepayments of Revolving Credit.

               The Borrowers shall make the mandatory prepayments (each a
"Revolving Credit Mandatory Prepayment" and collectively, the "Revolving Credit
Mandatory Prepayments") of the Revolving Credit at any time and from time to
time in such amounts requested by the Lender pursuant to Section 2.1.3
(Borrowing Base) in order to cover any Borrowing Base Deficiency.

               2.1.7 Optional Prepayments of Revolving Credit.

               The Borrowers shall have the option at any time and from time to
time to prepay (each a "Revolving Credit Optional Prepayment" and collectively
the "Revolving Credit

                                       27

<PAGE>

Optional Prepayments") advances under the Revolving Credit, in whole or in part
without premium or penalty.

               2.1.8 The Collateral Account.

               The Borrowers will deposit, or cause to be deposited, all Items
of Payment to a bank account designated by the Lender and from which the Lender
alone has power of access and withdrawal (the "Collateral Account"). Each
deposit shall be made not later than two (2) Business Days after the date of
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, each of 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 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 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.

               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. The Lender may debit the Revolving Loan Account for the
amount of any Item of Payment that is returned to the Lender unpaid. 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 twenty
five basis points (.25%) 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 in
arrears on the first day of each month, commencing on the first such date
following the date hereof, and on the Revolving Credit Termination Date.

   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, any of the Borrowers may, upon the
prior approval of the Lender, obtain standby or documentary 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. None of the Borrowers will 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
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

                                       29

<PAGE>

(including the face amount of the requested Letter of Credit) does not exceed
One Million Dollars ($1,000,000).

               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; Post-Expiration Date Letters of
Credit.

               Each Letter of Credit shall (a) be opened pursuant to a Letter of
Credit Agreement and (b) expire on a date that is the earlier of (i) one (1)
year from the date of issuance if a standby letter of credit or one hundred
eighty (180) days from the date of issuance if a documentary letter of credit or
(ii) 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 (each a
"Post-Expiration Date Letter of Credit" and collectively, the "Post-Expiration
Date Letters of Credit"), effective as of the Business Day preceding the
Revolving Credit Termination Date and without prior notice to or the consent of
the Borrowers, the Lender shall make advances under the Revolving Loan for the
account of the Borrowers in the aggregate face amount of all such Letters of
Credit. The Lender shall deposit the proceeds of such advances into one or more
non-interest bearing accounts with and in the name of the Lender and over which
the Lender alone shall have exclusive power of access and withdrawal
(collectively, the "Letter of Credit Cash Collateral Account"). The Letter of
Credit Cash Collateral Account is to be held by the Lender as additional
collateral and security for any Letter of Credit Obligations relating to the
Post-Expiration Date Letters of Credit. The Borrowers hereby assign, pledge,
grant and set over to the Lender a first priority security interest in, and Lien
on, all of the funds on deposit in the Letter of Credit Cash Collateral Account,
together with any and all Proceeds and products thereof as additional collateral
and security for the Letter of Credit Obligations relating to the
Post-Expiration Date Letters of Credit. The Borrowers acknowledge and agree that
the Lender shall be entitled to fund any draw or draft on any Post-Expiration
Date Letter of Credit from the monies on deposit in the Letter of Credit Cash
Collateral Account without notice to or consent of the Borrowers or the Lender.
The Borrowers further acknowledge and agree that the Lender's election to fund
any draw or draft on any Post-Expiration Date Letter of Credit from the Letter
of Credit Cash Collateral shall in no way limit, impair, lessen, reduce, release
or otherwise adversely affect the Borrowers' obligation to pay any Letter of
Credit Obligations under or relating to the Post-Expiration Date Letters of
Credit. At such time as all Post-Expiration Date Letters of Credit have expired
and all Letter of Credit Obligations relating to the Post-Expiration Date
Letters of Credit have been paid in full, the Lender agrees to apply the amount
of any remaining funds on deposit in the Letter of Credit Cash Collateral
Account to the then unpaid

                                       30

<PAGE>

balance of the Obligations under the Revolving Credit Facility in such order and
manner as the Lender shall determine in its sole and absolute discretion in
accordance with the provisions of this Agreement, and thereafter to 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, including, without limitation, any and all Post-Expiration Date
Letters of Credit, 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 and for which the Lender has been reimbursed by the
Borrowers in full in accordance with Section 2.2.5 (Payments of Letters of
Credit) and the Letter of Credit Agreements, and for which the Lender has no
further obligation or commitment to restore all or any portion of the amounts
drawn and reimbursed, is herein called the "Outstanding Letter of Credit
Obligations".

          2.2.4 Procedures for Letters of Credit.

          The Borrowers shall give the Lender written notice at least five (5)
Business Days prior to the date on which the Borrowers desire the Lender to
issue a Letter of Credit. Such notice shall be accompanied by a duly executed
Letter of Credit Agreement specifying, among other things: (a) the name and
address of the intended beneficiary of the Letter of Credit, (b) the requested
face amount of the Letter of Credit, (c) whether the Letter of Credit is to be
revocable or irrevocable, (d) the Business Day on which the Letter of Credit is
to be opened and the date on which the Letter of Credit is to expire, (e) the
terms of payment of any draft or drafts which may be drawn under the Letter of
Credit, and (f) any other terms or provisions the Borrowers desire to be
contained in the Letter of Credit. Such notice shall also be accompanied by such
other information, certificates, confirmations, and other items as the Lender
may require to assure that the Letter of Credit is to be issued in accordance
with the provisions of this Agreement and a Letter of Credit Agreement. In the
event of any conflict between the provisions of this Agreement and the
provisions of a Letter of Credit Agreement, the provisions of this Agreement
shall prevail and control unless otherwise expressly provided in the Letter of
Credit Agreement. Upon (x) receipt of such notice, (y) payment of all Letter of
Credit Fees and all other Fees payable in connection with the issuance of such
Letter of Credit, and (z) receipt of a duly executed Letter of Credit Agreement,
the Lender shall process such notice and 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 Payments of Letters of Credit.

          The Borrowers hereby promise to pay to the Lender, ON DEMAND and in
United States Dollars, the following which are herein collectively referred to
as the "Current Letter of Credit Obligations":

                (a) the amount which the Lender has paid or will be required to
     pay under each draft or draw on a Letter of Credit, whether such demand be
     in advance of the Lender's payment or for reimbursement for such payment;

                                       31

<PAGE>

                (b) any and all reasonable charges and expenses which the Lender
     may pay or incur relative to the Letter of Credit and/or such draws or
     drafts; and

                (c) interest on the amounts described in (a) and (b) not paid by
     the Borrowers as and when due and payable under the provisions of (a) (when
     paid by the Lender) and (b) above from the day the same are due and payable
     until paid in full at a rate per annum equal to the then current highest
     rate of interest on the Revolving Loan.

          In addition, the Borrowers hereby promise to pay any and all other
Letter of Credit Obligations as and when due and payable in accordance with the
provisions of this Agreement and the Letter of Credit Agreements. The obligation
of the Borrowers to pay Current Letter of Credit Obligations and all other
Letter of Credit Obligations shall be absolute and unconditional under any and
all circumstances and irrespective of any setoff, counterclaim or defense to
payment which the Borrowers or any other account party may have or have had
against the beneficiary of such Letter of Credit, the Lender, or any other
Person, including, without limitation, any defense based on the failure of any
draft or draw to conform to the terms of such Letter of Credit, any draft or
other document proving to be forged, fraudulent or invalid, or the legality,
validity, regularity or enforceability of such Letter of Credit, any draft or
other documents presented with any draft, any Letter of Credit Agreement, this
Agreement, or any of the other Financing Documents, all whether or not the
Lender had actual or constructive knowledge of the same, and irrespective of any
Collateral, security or guarantee therefore or right of offset with respect
thereto and irrespective of any other circumstances whatsoever which
constitutes, or might be construed to constitute, an equitable or legal
discharge of the Borrowers for any Letter of Credit Obligations, in bankruptcy
or otherwise; provided, however, that the Borrowers shall not be obligated to
reimburse the Lender for any wrongful payment under such Letter of Credit made
as a result of the Lender's willful misconduct or gross negligence. The
obligation of the Borrowers to pay the Letter of Credit Obligations shall not be
conditioned or contingent upon the pursuit by the Lender or any other Person at
any time of any right or remedy against any Person which may be or become liable
in respect of all or any part of such obligation or against any Collateral,
security or guarantee therefore or right of offset with respect thereto.

          The Letter of Credit Obligations shall continue to be effective, or be
reinstated, as the case may be, if at any time payment of all or any portion of
the Letter of Credit Obligations is rescinded or must otherwise be restored or
returned by the Lender upon the insolvency, bankruptcy, dissolution, liquidation
or reorganization of any Person, or upon or as a result of the appointment of a
receiver, intervenor, or conservator of, or trustee or similar officer for, any
Person, or any substantial part of such Person's property, all as though such
payments had not been made.

          2.2.6 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

                                       32

<PAGE>

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 statement in reasonable detail
explaining the nature and calculation of the increased cost, the Borrowers 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
Borrowers, shall be conclusive, absent manifest error.

          2.2.7 General Letter of Credit Provisions.

          The Borrowers hereby instruct the Lender to pay any draft complying
with the terms of any Letter of Credit irrespective of any instructions of the
Borrowers to the contrary. The Borrowers assume all risks of the acts and
omissions of the beneficiary and other users of any Letter of Credit. The Lender
and its respective branches, Affiliates and/or correspondents shall not be
responsible for and the Borrowers hereby indemnify and hold the Lender and its
branches, Affiliates and/or correspondents harmless from and against all
liability, loss and expense (including reasonable attorney's fees and costs)
incurred by the Lender and/or its respective branches, Affiliates and/or
correspondents relative to and/or as a consequence of (a) any failure by the
Borrowers to perform the agreements hereunder and under any Letter of Credit
Agreement, (b) any Letter of Credit Agreement, this Agreement, any Letter of
Credit and any draft, draw and/or acceptance under or purported to be under any
Letter of Credit, (c) any action taken or omitted by the Lender and/or any of
its respective branches, Affiliates and/or correspondents at the request of the
Borrowers, (d) any failure or inability to perform in accordance with the terms
of any Letter of Credit by reason of any control or restriction rightfully or
wrongfully exercised by any de facto or de jure Governmental Authority, group or
individual asserting or exercising governmental or paramount powers, and/or (e)
any consequences arising from causes beyond the control of the Lender and/or any
of its respective branches, Affiliates and/or correspondents.

          Except for willful misconduct, the Lender and its respective branches,
Affiliates and/or correspondents, shall not be liable or responsible in any
respect for any (a) error, omission, interruption or delay in transmission,
dispatch or delivery of any one or more messages or advices in connection with
any Letter of Credit, whether transmitted by cable, telegraph, mail or otherwise
and despite any cipher or code which may be employed, and/or (b) action,
inaction or omission which may be taken or suffered by it or them in good faith
or through inadvertence in identifying or failing to identify any beneficiary or
otherwise in connection with any Letter of Credit.

          Any Letter of Credit may be amended, modified or revoked only upon the
receipt by the Lender from the Borrowers and the beneficiary (including any
transferee and/or assignee of the original beneficiary), of a written consent
and request therefore.

          If any Laws, order of court and/or ruling or regulation of any
Governmental Authority of the United States (or any state thereof) and/or any
country other than the United States permits a beneficiary under a Letter of
Credit to require the Lender and/or any

                                       33

<PAGE>

of its respective branches, Affiliates and/or correspondents to pay drafts under
or purporting to be under a Letter of Credit after the expiration date of the
Letter of Credit, the Borrowers shall reimburse the Lender, as appropriate, for
any such payment pursuant to provisions of Section 2.2.6 (Change in Law;
Increased Cost).

                  Except as may otherwise be specifically provided in a Letter
of Credit or Letter of Credit Agreement, the laws of the State and the Uniform
Customs and Practice for Documentary Credits, 1993 Revision, International
Chamber of Commerce Publication No. 500 shall govern the Letters of Credit. The
Laws, rules, provisions and regulations of the Uniform Customs and Practice for
Documentary Credits are hereby incorporated by reference. In the event of a
conflict between the Uniform Customs and Practice for Documentary Credits and
the laws of the State, the Uniform Customs and Practice for Documentary Credits
shall prevail.

     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 and the benefits of
Letters of 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, apply for and direct the benefits of
Letters of 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 and the benefit of such
Letter of 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,

                                       34

<PAGE>

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.

                  Each of the Borrowers hereby irrevocably authorizes the Lender
(in its sole discretion) to make advances under the Revolving Credit and to
issue or cause to be issued Letters of Credit for the account of any or all of
the Borrowers, 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 Loan, any Letter of 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 2.3.11 (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.

                                       35

<PAGE>

          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.

          2.3.3 Origination Fee.

          The Borrower shall pay to the Lender on or before the Closing Date the
a loan origination fee (the "Origination Fee") in the amount of Thirty Seven
Thousand Five Hundred Dollars ($37,500), which fee has been fully earned and is
non-refundable, Twenty Thousand Dollars ($20,000) of which has been paid prior
to the Closing Date.

          2.3.4 Monitoring Fees.

          The Borrower shall pay to the Lender a monthly monitoring fee in the
amount of Five Hundred and Fifty Dollars ($550), plus any and all reasonable out
of pocket expenses and travel time incurred by the Lender (collectively, the
"Monitoring Fees" and individually a "Monitoring Fee"), which Monitoring Fees
shall be payable 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 Base Rate
shall become effective as of the opening of business on the day on which such
change in the Base 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

                                       36

<PAGE>

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 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. At its sole discretion, the Lender may charge any deposit
account of the Borrowers at the Lender or any Affiliate of the Lender with all
or any part of any amount due to the Lender under this Agreement or any of the
other Financing Documents to the extent that the Borrowers shall have not
otherwise tendered payment to the Lender.

          2.3.8 Liens; Setoff.

          The Borrowers hereby grant to the Lender as additional collateral and
security for all of the Obligations a continuing Lien on any and all monies,
Investment Property, 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

                                       37

<PAGE>

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 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 agree 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.

          2.3.11 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.

                (b)  The obligations and liabilities of each Borrower as a
guarantor under this Section 2.3.11 shall be absolute and unconditional and
joint and several, irrespective of the genuineness, validity, priority,
regularity or enforceability of this Agreement,

                                       38

<PAGE>

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 2.3.11 were not in effect;

                    (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 2.3.11, or any other guarantor; and

                                       39

<PAGE>

                    (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 2.3.11, 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 2.3.11, 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
2.3.11, 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 2.3.11 in any manner whatsoever, and this Section 2.3.11
shall remain and continue in full force and effect. It is the intent and purpose
of this Section 2.3.11 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 2.3.11, 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 2.3.11,
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 2.3.11 and of
          presentment, demand and protest thereof;

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

                                       40

<PAGE>

                                    (iv)   notice of any increase in the amount
          of any of or all of the indebtedness guaranteed by this Section
          2.3.11;

                                    (v)    demand for observance, performance or
          enforcement of any of the terms or provisions of this Section 2.3.11,
          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 2.3.11, 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.

parties to this Agreement, and no others, unless such Subsidiaries have been
released from liability under this Agreement pursuant to a written agreement by

good standing under the laws of the jurisdiction in which it is organized, (c)
has the power to own its property and to carry on its business as now being
conducted, and (d) is duly qualified to do business and is in good standing in

                    Each  Borrower has full power and authority to execute and

party, to make the borrowings under this Agreement and to incur and perform the
Obligations whether under this Agreement, the other Financing Documents, all of
which have been duly authorized by all proper and necessary action. No consent
or approval of shareholders or any creditors of any Borrower, and no consent,

respective terms, subject to bankruptcy, insolvency,

                    4.1.5    No Conflicts.

                    Neither the execution, delivery and performance of the terms
of this Agreement or of any of the other Financing Documents executed and
delivered by any Borrower nor the consummation of the transactions contemplated
by this Agreement will conflict with, violate or be prevented by (a) any
Borrower's organizational or governing documents, (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.

                             (b)    None of the Borrowers nor any of their
respective Subsidiaries is in default under or with respect to any obligation

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 of its properties, the violation of which,
considered in the aggregate, could result in a Material Adverse Effect.

                    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 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 1958, as
amended, or any rules or regulations promulgated under any of such statutes.

Subsidiaries is an investment company within the meaning of the Investment
Company Act of 1940, as amended, nor is it, directly or indirectly, controlled
by or acting on behalf of any Person which is an

                                       44

Part 221), of the Board of Governors of the Federal Reserve System.

                    4.1.10   Litigation.

                    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
March 31, 2002, 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 each Borrower's knowledge no such adverse change is pending. None
of the Borrowers nor any Subsidiary has guaranteed the obligations of, or made
any investment in or advances to, any Person, except as permitted under this
Agreement or as disclosed in the most recent financial statements delivered by
the Company to the Lender.

                    4.1.12   Full Disclosure.

(Financial Condition), 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) 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 4.1.13 attached hereto and made a part hereof, the Borrowers have no
Indebtedness for Borrowed Money. The Lender has received photocopies of all
promissory notes evidencing any Indebtedness for Borrowed Money set forth in
Schedule 4.1.13, together with any and all

                                       45

<PAGE>

subordination agreements, other 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 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."

          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, subject to Permitted
Liens. 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

controversies pending or, to the best knowledge of the Borrowers after due
inquiry, threatened between any Borrower and its employees, and (d) no Borrower

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

          4.1.20 Presence of Hazardous Materials or Hazardous Materials

                                       47

          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

identifies (a) the type of entity, the state of its organization and 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.

or employees has received any notice of, or information concerning, any
proposed, contemplated or initiated suspension or debarment, be it temporary or
permanent, due to an administrative or a statutory basis, of any Borrower by any
Governmental Authority. Each Borrower further warrants and represents that no
Borrower has defaulted under any Government Contract which default would be a
basis of terminating such Government Contract.

          4.1.25 Equipment.

on a sale on approval basis.

          4.1.26 Accounts.

part of the Excluded Assets) and to the best of each Borrower's knowledge (a)

evidenced by a judgment, an Instrument, or Chattel Paper (unless such judgment

deposits required by applicable Laws including, without limitation, payments or
deposits with respect to amounts withheld by any of the Borrowers from wages and

privilege for the account of, and in trust for, the Lender of collecting their
Receivables and receiving in respect thereto all Items of Payment and shall
otherwise completely service all of the Receivables including (a) the billing,
posting and maintaining of complete records applicable thereto, (b) the taking
of such action with respect to the Receivables as the Lender may request or in
the absence of such request, as each of the Borrowers may deem advisable; and

revoke the collection privilege given in this Agreement to any one or more of
the Borrowers by either giving notice of its assignment of, and Lien on the
Collateral to the Account Debtors or giving notice of such revocation to the

failure to collect or enforce any of the Receivables or to preserve any rights
against any other party with an interest in the Collateral. The Lender shall be
entitled at any time and from time to time to confirm and verify Receivables.

thereof,

                                       61

<PAGE>

that neither any assignment to the Lender nor any other provision contained in
this Agreement or any of the other Financing Documents shall impose on the

which is assigned and the Borrowers hereby agree jointly and severally to
indemnify the Lender and hold the Lender harmless from any and all claims,
actions, suits, losses, damages, costs, expenses, fees, obligations and

amount of the Obligations or the fair market value of the Equipment (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) file with the Lender, upon its
request, a detailed list of the insurance then in 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 covered thereby; and (c) within
thirty (30) days after notice in writing from the Lender, obtain such additional
insurance as the Lender may reasonably request.

          6.1.19 Maintenance of the Collateral.

          The Borrowers will cause the Lender to have at all times 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. In addition, the Borrowers will maintain the
Collateral in good working order, saving and excepting ordinary wear and tear,
and will not permit anything to be done to the Collateral which may materially
impair the value thereof. The Lender, or an agent designated by the Lender,
shall be permitted to enter the premises of each of the Borrowers and their
Subsidiaries and examine, audit and inspect the Collateral at any reasonable
time and from time to time without notice. The Lender shall not have any duty
to, and the Borrowers hereby release the Lender from all claims of loss or
damage caused by the delay or failure to collect or enforce any of the

          6.1.21 Defense of Title and Further Assurances.

          At their expense, the Borrowers will defend the title to the
Collateral (and any part thereof), and will immediately execute, acknowledge and
deliver any 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 this Agreement, under any
of the other Financing Documents and the first priority of that Lien, subject
only to the Permitted Liens. The Borrowers hereby authorize the filing of any
financing statement or continuation statement required under the Uniform
Commercial Code. 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 Lien upon, pledge of, or paramount security interest
in, the Collateral, subject to the Permitted Liens. The Borrowers shall pay to
the Lender on demand all taxes, costs and expenses incurred by the Lender in
connection with the preparation, execution, recording and filing of any such
document or instrument. To the extent that the proceeds of any of the Accounts
or Receivables of the Borrowers are expected to become subject to the control
of, or in the possession 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, 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. 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 6.1.21.

          6.1.22 Business Names; Locations.

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).

          6.1.23 Use of Premises and Equipment.

          The Borrowers agree that until the Obligations are fully paid and the
Revolving Credit Commitment has been terminated or have expired, the Lender (a)
after and during the continuance of an Event of Default, may use any of the
Borrowers' owned or leased lifts, hoists, trucks and other facilities or
equipment for handling or removing the Collateral; and (b) shall have, and is
hereby granted, a right of ingress and egress to the places where the

                                       63

<PAGE>

Collateral is located, and may proceed over and through any of the Borrowers'
owned or leased property.

          6.1.24 Protection of Collateral.

          The Borrowers agree that the Lender may at any time following an Event
of Default take such steps as the Lender deems reasonably necessary to protect
the interest of the Lender in, and to preserve the Collateral, including, the
hiring of such security guards or the placing of other security protection
measures as the Lender deems appropriate, may employ and maintain at any of the
Borrowers' premises a custodian who shall have full authority to do all acts
necessary to protect the interests of the Lender in the Collateral and may lease
warehouse facilities to which the Lender may move all or any part of the
Collateral to the extent commercially reasonable. The Borrowers agree to
cooperate fully with the Lender's efforts to preserve the Collateral and will
take such actions to preserve the Collateral as the Lender may reasonably
direct. All of the Lender's expenses of preserving the Collateral, including any
reasonable expenses relating to the compensation and bonding of a custodian,
shall be part of the Enforcement Costs.

          So long as any of the Obligations or the Revolving Credit Commitment
therefor shall be outstanding hereunder, the Borrowers agree with the Lender

transfer of assets to a Borrower, or consolidation with or transfer of assets to
any other Subsidiary of a Borrower; (b) the disposition prior to a Default of
tangible property included in the Collateral, which, in each case, a Borrower

or (e) any Wholly-Owned Subsidiary of any Additional Borrower may be merged into
or consolidated with such Additional Borrower in which such Subsidiary is not
the surviving corporation or entity. None of the Borrowers will enter into any
merger or consolidation or amalgamation without the Lender's prior consent,
which consent will not be unreasonably withheld, but which consent will be based
on such conditions as the Lender deems appropriate in its sole but reasonable
discretion. None of the Borrowers nor any of the Subsidiaries will directly or
indirectly enter into any arrangement to sell or transfer all or any substantial
part of its fixed assets (other than the Flight Assets on terms and conditions
acceptable to the Lender) and thereupon or within one year thereafter rent or
lease the assets so sold or transferred. Any

of directors; or (b) the issuance of stock options to employees, officers and
directors of any Borrower as approved by such Borrower's board of directors.

6.2.4 until the Lender has received written notice from such Borrower at least
ten (10) Business Days in advance of declaring or paying any such dividend and
has also received such other information as the Lender may have requested in
order to verify the amount of the proposed dividends and to determine that all
of the conditions precedent to the making of the requested dividends have been
satisfied.

but is unable to complete such cure within such ten (10) day period, the

                                       72

     Section 7.2    Remedies.

     Upon the occurrence and during the continuance of any Event of Default, the
Lender may, in the exercise of its sole and absolute discretion from time to
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 Section 7.1.6 (Receiver;
Bankruptcy) or Section 7.1.7 (Involuntary Bankruptcy, etc.), the Revolving
Credit Commitment and any agreement in any of the Financing Documents to provide
additional credit and/or issue Letters of 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 Investment
Property 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

their number, nature of business and investment intention, including, without
limitation, a requirement that the Persons making such purchases represent and

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.

     proceedings brought in respect thereof;

                             (h)    endorse or sign the name of any Borrower

                    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

                                       75

<PAGE>

paid by the Borrowers to the Lender on demand, and shall constitute and become a
part of the Obligations.

                 7.2.7 Other Remedies.

                 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
control or custody of, or on deposit with, the Lender or any Affiliate of the
Lender.

signed by the Lender and the Borrowers. No waiver of any provision of this
Agreement or of any of the other Financing

                                       76

<PAGE>

Documents, nor consent to any departure by the Borrowers therefrom, shall in any
event be effective unless the same shall be in writing signed by the Lender. No
course of dealing between the Borrowers and the Lender and no act or failure to
act from time to time on the part of the Lender shall constitute a waiver,
amendment or modification of any provision of this Agreement or any of the other
Financing Documents or any right or remedy under this Agreement, under any of
the other Financing Documents or under applicable Laws.

     Section 8.3 Cumulative Remedies.

     The rights, powers and remedies provided in this Agreement and in the other
Financing Documents are cumulative, may be exercised concurrently or separately,
may be exercised from time to time and in such order as the Lender shall
determine, subject to the provisions of this Agreement, and are in addition to,
and not exclusive of, rights, powers and remedies provided by existing or future
applicable Laws. In order to entitle the Lender to exercise any remedy reserved
to it in this Agreement, it shall not be necessary to give any notice, other
than such notice as may be expressly required in this Agreement.

     Section 8.4 Severability.

     In case one or more provisions, or part thereof, contained in this
Agreement or in the other Financing Documents shall be invalid, illegal or
unenforceable in any respect under any Law, then without need for any further
agreement, notice or action:

                     (a) the validity, legality and enforceability of the
     remaining provisions shall remain effective and binding on the parties
     thereto and shall not be affected or impaired thereby;

                     (b) the obligation to be fulfilled shall be reduced to the
     limit of such validity;

                     (c) if such provision or part thereof pertains to repayment
     of the Obligations, then, at the sole and absolute discretion of the
     Lender, all of the Obligations of the Borrowers to the Lender shall become
     immediately due and payable; and

                     (d) if the affected provision or part thereof does not
     pertain to repayment of the Obligations, but operates or would
     prospectively operate to invalidate this Agreement in whole or in part,
     then such provision or part thereof only shall be void, and the remainder
     of this Agreement shall remain operative and in full force and effect.

     Section 8.5 Assignments by Lender.

     The Lender may, without notice to or consent of the Borrowers, assign to
any Person (an "Assignee") all of the Lender's Revolving Credit Commitment. The
Lender and its Assignee shall notify the Borrowers in writing of the date on
which the assignment is to be effective (the "Adjustment Date"). On or before
the Adjustment Date, the assigning Lender, the Borrowers and the respective
Assignee shall execute and deliver a written assignment agreement in a form
acceptable to the Lender, which shall constitute an amendment to this Agreement
to the extent

                                       77

<PAGE>

necessary to reflect such assignment. Upon the request of any assigning Lender
following an assignment made in accordance with this Section 8.5, the Borrowers
shall issue new Notes to the assigning Lender and its Assignee reflecting such
assignment, in exchange for the existing Notes held by the assigning Lender.

     In addition, the Lender may at any time pledge all or any portion of the
Lender's rights under this Agreement, the Revolving Credit Commitment or any of
the Obligations to a Federal Reserve Bank.

     Section 8.6 Participations by Lender.

     The Lender may at any time sell to one or more financial institutions
participating interests in any of the Lender's Obligations or Revolving Credit
Commitment; provided, however, that (a) no such participation shall relieve the
Lender from its obligations under this Agreement or under any of the other
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 shall continue to deal solely and directly with the Lender in
connection with the Lender's rights and obligations under this Agreement and the
other Financing Documents.

     Section 8.7 Disclosure of Information by Lender.

Lender in accordance with Section 8.5 (Assignments by Lender) or Section 8.6

records, information, reports, financial statements and documents obtained in
connection with this Agreement and/or any of the other Financing Documents or
otherwise.

     Section 8.8 Successors and Assigns.

     This Agreement and all other Financing Documents shall be binding upon and

certificate delivered pursuant hereto or thereto shall survive the making by the
Lender of the Revolving Credit and the execution and delivery of the Notes,
shall be binding upon the Borrowers regardless of how long before or after the
date hereof any of the Obligations were or are incurred, and shall continue in
full force and effect so long as any of the Obligations are outstanding and
unpaid. From time to time upon the Lender's request, and also as a condition of
the release of any one or more of the Security Documents, the Borrowers and
other Persons obligated with respect to the Obligations shall provide the Lender
with such acknowledgments and agreements as the Lender may require, to the
effect that there exists no defenses, rights of setoff or recoupment, claims,
counterclaims, actions or causes of action of any kind or nature whatsoever
against the Lender and/or any of its

                                       78

<PAGE>

together with interest thereon from the date incurred or advanced until paid in
full at a per annum rate of interest equal at all times to the Post-Default

repayment of the other Obligations and shall survive the termination of this
Agreement.

     Section 8.11 Applicable Law; Jurisdiction.

                  8.11.1 Applicable Law.

                  Borrowers acknowledge and agree that the Financing Documents,
including, this Agreement, shall be governed by the Laws of the State, as if
each of the Financing Documents and this Agreement had each been executed,
delivered, administered and performed solely within the State even though for
the convenience and at the request of the Borrowers, one or more of the
Financing Documents may be executed elsewhere. The Lender acknowledges, however,
that remedies under certain of the Financing Documents that relate to property
outside the State may be subject to the laws of the state in which the property
is located.

                  8.11.2 Submission to Jurisdiction.

                  The Borrowers irrevocably submit to the jurisdiction of any
state or federal court sitting in the State over any suit, action or proceeding
arising out of or relating to this Agreement or any of the other Financing
Documents. Each of the Borrowers irrevocably waives, to the fullest extent
permitted by law, any objection that it may now or hereafter have to the laying
of the venue of any such suit, action or proceeding brought in any such court
and any claim that any such suit, action or proceeding brought in any such court
has been brought in an inconvenient forum. Final judgment in any such suit,
action or proceeding brought in any such court shall be conclusive and binding
upon the Borrowers and may be enforced in any court in which the Borrowers are
subject to jurisdiction, by a suit upon such judgment, provided that service of
process is effected upon the Borrowers in one of the manners specified in this
Section or as otherwise permitted by applicable Laws.

                  8.11.3 Appointment of Agent for Service of Process.

                  The Borrowers hereby irrevocably designate and appoint Julia

20024, as the Borrowers' authorized agent to receive on the Borrowers' behalf
service of any and all process that may be served in any suit, action or
proceeding of the nature referred to in this Section in any state or federal
court sitting in the State. If such agent shall cease so to act, the Borrowers
shall irrevocably designate and appoint without delay another such agent in the
State satisfactory to the Lender and shall promptly deliver to the Lender
evidence in writing of such other agent's acceptance of such appointment and its
agreement that such appointment shall be irrevocable.

                                       79

prepaid, return receipt requested, to the Borrower at the Borrower's address
designated in or pursuant to Section 8.1 (Notices), and (b) serving a copy
thereof upon the agent, if any, designated and appointed by the Borrower as the
Borrower's agent for service of process by or pursuant to this Section. The
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.

     Section 8.12 Duplicate Originals and Counterparts.

     This Agreement may be executed in any number of duplicate originals or
counterparts, each of such duplicate originals or counterparts shall be deemed
to be an original and all taken together shall constitute but one and the same
instrument.

     Section 8.13 Headings.

     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
the Collateral wherever the same may be located and regardless of the cause
thereof other than Collateral in its possession. The Lender shall not, by
anything herein or in any of the Financing Documents or otherwise, assume any of

Lender, and the Lender shall not be responsible in any way for the performance
by the Borrowers of any of the terms and conditions thereof.

succeeding Business Day and in the case of principal, interest shall be payable
thereon at the rate per annum specified in the Notes during such extension.

     Section 8.16 Entire Agreement.

     This Agreement is intended by the Lender and the Borrowers to be a
complete, exclusive and final expression of the agreements contained herein.

prior agreements pertaining to the matters addressed by

                                       80

<PAGE>

this Agreement but shall look solely to this Agreement for definition and
determination of all of their respective rights, liabilities and
responsibilities under this Agreement.

     Section 8.17 Waiver of Trial by Jury.

     EACH OF THE BORROWERS AND THE LENDER HEREBY WAIVES TRIAL BY JURY IN ANY

INCLUDING CLAIMS AGAINST PARTIES WHO ARE NOT PARTIES TO THIS AGREEMENT.

     This waiver is knowingly, willingly and voluntarily made by the Borrowers
and the Lender, and the Borrowers and the Lender hereby represent that no
representations of fact or opinion have been made by any individual to induce
this waiver of trial by jury or to in any way modify or nullify its effect. The
Borrowers and the Lender further represent that they have been represented in
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.

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.

parent and Affiliates of the Lender and the respective parent's and Affiliates'
