                                 ARTICLE II
                           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 Loan".  The
Lender's "Revolving Credit Committed Amount" is $25,000,000.  During the
Revolving Credit Commitment Period, any or all of the Borrowers may request
advances under the Revolving Credit Facility in accordance with the provisions
of this Agreement; provided that after giving effect to any Borrower's request
the aggregate outstanding principal balance of the Revolving Loan and all
Letter of Credit Obligations would not exceed the lesser of (i) the Revolving
Credit Committed Amount or (ii) the 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.  Interest on the
Revolving Loan shall be payable on each Interest Payment Date.

                      2.1.2	Procedure for Making Advances Under the
                                ---------------------------------------
Revolving Loan; Lender Protection Loans.
----------------------------------------
                      The Borrowers may borrow under the Revolving Credit
Facility on any Business Day.  Advances under the Revolving Loan shall be
deposited to a demand deposit account of a Borrower with the Lender or shall be
otherwise applied as directed by the Borrowers, which direction the Lender may
require to be in writing.  Not later than 1:00 p.m. (Eastern Time) on the date
of the requested borrowing, the Borrowers 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 and if requested by the Lender, be
accompanied by a Borrowing Base Report.  Any oral Loan Notice shall be
confirmed in writing by the Borrowers within three (3) Business Days after the
making of the requested advance under the Revolving Loan.  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
Loan, and irrevocably authorizes the Lender 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 under this Agreement, including, without limitation, advances
and reserves under the Revolving Loan 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 Loan that the Lender may advance or the Lender may
reserve hereunder exceeds the Total Revolving Credit Committed Amount or the
Borrowing Base.

                      2.1.3	Borrowing Base.
                                ---------------
                      As used in this Agreement, the term "Borrowing Base" means
at any time, an amount equal to the sum of (i) eighty percent (80%) of the
amount of Eligible Receivables and (ii) ninety percent (90%) of Eligible
Receivables derived from Government Contracts.  Any Eligible Receivables
acquired by any of the Borrowers in connection with any Permitted Acquisition
shall not be included in the Borrowing Base without the prior consent of the
Lender.

                      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 Loan.
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 Loan 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 ON 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.
                                ----------------------
                      The Borrowers will furnish to the Lender no less
frequently than monthly before the 20th 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 completed and duly
signed.  The Borrowing Base Report shall contain the net amount due 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.  Upon the Lender's request and upon the creation of any
Receivables, or at such intervals as the Lender may require, the Borrowers will
provide the Lender with (a) confirmatory assignment schedules; (b) copies of
Account Debtor invoices; (c) evidence of shipment or delivery; and (d) such
further schedules, documents and/or information regarding the Receivables as the
Lender may reasonably require. The items to be provided under this subsection
shall be in form satisfactory to the Lender, and certified as true and correct
by a Responsible Officer, and delivered to the Lender from time to time solely
for the Lender's convenience in maintaining records of the Collateral.  Any
Borrower's failure to 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 joint and several obligation of the Borrowers to pay
the Revolving Loan, 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.
The Revolving Credit Note shall be dated as of the Closing Date, shall be
payable to the order of the Lender 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 Loan outstanding from time to
time exceeds the Revolving Credit Committed Amount, the excess shall bear
interest at the rates provided from time to time for advances under the
Revolving Loan evidenced by the Revolving Credit Note and shall be payable,
with accrued interest, ON DEMAND.

                      2.1.6	Mandatory Prepayments of Revolving Loan.
                                ----------------------------------------
                      The Borrowers shall make the mandatory prepayments (each a
"Revolving Loan Mandatory Prepayment" and collectively, the "Revolving Loan
Mandatory Prepayments") of the Revolving Loan 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 Loan.
                                ---------------------------------------
                      The Borrowers shall have the option at any time and from
time to time to prepay (each a "Revolving Loan Optional Prepayment" and
collectively the "Revolving Loan Optional Prepayments") the Revolving Loan, in
whole or in part without premium or penalty.

                      2.1.8	The Collateral Account.
                                -----------------------
                      Upon request of the Lender after the occurrence of a
Default, 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 the next Business Day 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, which
endorsement the Borrowers hereby agree to make.  In the event the Borrowers
fail to do so, the Borrowers hereby authorize the Lender to make the
endorsement in the name of any or all of the Borrowers.  Prior to such a
deposit, the Borrowers will not commingle any Items of Payment with any of the
Borrowers' other funds or property, but will hold them separate and apart in
trust and for the account of the Lender.

                      In addition, if so directed by the Lender, the Borrowers
shall direct the mailing of all Items of Payment from their Account Debtors to
one or more post-office boxes 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.

                      The Borrowers hereby authorize the Lender after the
occurrence of a Default to inspect all Items of Payment, endorse all Items of
Payment in the name of any or all of the Borrowers, and deposit such 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.  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 after the occurrence of a Default apply
the whole or any part of the collected funds credited to the Collateral Account
against the Revolving Loan (or with respect to Items of Payment which are not
proceeds of Accounts or Inventory or after an Event of Default, against any of
the Obligations) or credit such collected funds to a depository account of any
or all of the Borrowers with the Lender, the order and method of such
application to be in the sole discretion of the Lender.

                      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 Loan made by the
Lender hereunder as of the date made, (ii) the amount of any interest accrued
on the Revolving Loan 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 Loan, 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 Loan as of the date
made.  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, ON 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 presumed conclusively
to be correct, and shall constitute an account stated between the Lender and
the Borrowers unless the Lender receives specific written objection thereto
from any Borrower within thirty (30) Business Days after such statement or
reconciliation shall have been sent by the Lender.  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.
                                ---------------------------------
                      Borrowers shall pay to Lender a revolving credit facility
fee (collectively, the "Revolving Credit Unused Line Fees" and individually, a
"Revolving Credit Unused Line Fee") in an amount equal to ten (10) basis
points annum of the average daily unused and undisbursed portion of the
Revolving Credit Committed Amount in effect from time to time accruing during
each calendar quarter.  The accrued and unpaid portion of the Revolving Credit
Unused Line Fee shall be paid by Borrowers to Lender on the last day of each
quarter, commencing on the first such date following the date hereof, and on
the Revolving Credit Termination Date.

                      2.1.11	Optional Reduction of Total Revolving Credit
                                --------------------------------------------
Committed Amount.
-----------------
                      The Borrowers shall have the right to reduce permanently
(each a "Revolving Credit Optional Reduction" and collectively the "Revolving
Credit Optional Reductions") the Total Revolving Credit Committed Amount in
effect from time to time in the amount of any integral multiple of One Million
Dollars ($1,000,000), upon at least fifteen (15) Business Days prior written
notice to the Lender specifying the date and amount of such Revolving Credit
Optional Reduction; provided, that no Revolving Credit Optional Reduction
shall be permitted if, (i) after giving effect thereto and to any Revolving
Loan Optional Prepayment made on the effective date thereof, the then
outstanding principal amount of the Revolving Loan and Outstanding Letter of
Credit Obligations exceeds the Total Revolving Credit Committed Amount as so
reduced or (ii) after giving effect to such Revolving Credit Optional
Reduction there is not at least Five Million Dollars ($5,000,000) of
availability under the Revolving Loan.  Such notice shall be irrevocable as to
the amount and date of such Revolving Credit Optional Reduction.

       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 Commitments, each of the Borrowers, upon the
prior approval of the Lender, may obtain standby letters of credit (as the
same may from time to time be amended, supplemented or otherwise modified,
each a "Letter of Credit" and collectively the "Letters of Credit") from the
Lender from time to time from the Closing Date until the Business Day
preceding the Revolving Credit Termination Date.  The Borrowers will not be
entitled to obtain a Letter of Credit unless (a) the Borrowers are then able
to obtain a Revolving Loan from the Lender in an amount not less than the
proposed face amount of the Letter of Credit requested by the Borrowers, and
(b) the sum of the then Outstanding Letter of Credit Obligations (including
the amount of the requested Letter of Credit), unless otherwise agreed to by
the Lender, does not exceed Five Million Dollars ($5,000,000).

                      2.2.2	Letter of Credit Fees.
                                ----------------------
                      With respect to each Letter of Credit, the Borrowers shall
pay to the Lender, for its own account, an issuance fee of one hundred twenty-
five (125) basis points per annum of the stated amount of each Letter of
Credit all without regard for provisions contained in the Letters of Credit
which may give rise to a reduction in the stated amount thereof unless such
reduction has actually occurred (each a "Letter of Credit Fronting Fee" and
collectively, the "Letter of Credit Fees").  The Letter of Credit Fees shall
be paid upon the opening of each Letter of Credit and upon each anniversary
thereof, if any.  In addition, the Borrowers shall pay to the Lender all other
reasonable and customary amendment, negotiation, processing, transfer or other
fees to the extent and as and when required by the provisions of any Letter of
Credit Agreement.  All Letter of Credit Fees and all such other additional
fees are included in and are a part of the "Fees" payable by the Borrowers
under the provisions of this Agreement and are for the sole and exclusive
benefit of the Lender.

                      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 not later than the
Business Day preceding the Revolving Credit Expiration Date; provided,
however, if any Letter of Credit does have an expiration date later than the
Business Day preceding the Revolving Credit Termination Date (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 may 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 may in its sole and absolute discretion issue or refuse to
issue any Letter of Credit which is automatically renewable or "evergreen".
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.
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 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.

                      Each Letter of Credit shall be issued for purposes
acceptable to Lender.  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
and 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 Borrower desires 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.  The Lender shall not be obligated to issue any
Letter of Credit where the expiration date automatically renews or is
"evergreen".
                      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;

                      (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) and (b) above from the day the same
are due and payable until paid in full at a rate per

                      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 therefor 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.
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 therefor 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 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 (which increase in cost shall be the result of the
Lender's reasonable allocation of the aggregate of such cost increases
resulting from such events), then, upon demand by the Lender, 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 Loan.  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 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 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 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 branches, Affiliates and/or
correspondents.

                      Except for willful misconduct, the Lender and its
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 therefor.

                      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 of their 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    Interest.
                      ---------
                      2.3.1	General Provisions.
                                -------------------
       All payments hereunder (including any payment or prepayment of
principal, interest, fees and other charges) or with respect to the Notes or
the Loans shall be made in lawful money of the United States of America, in
immediately available funds without set-off, deduction or counterclaim of any
kind, to the Lender, at its office at 8521 Leesburg Pike, Suite 405 Vienna,
Virginia 22182, or at such other place as the Lender may in writing designate,
and shall be applied, first to accrued Obligations other than principal and
interest, next to accrued interest, then to principal due on Loans bearing
interest at the Prime-based Rate, and last to interest due on Loans bearing
interest at a LIBOR-based Rate the last day of the Interest Period applicable
thereto, unless the Interest Period is six months, in which case interest
shall be due quarterly on the last day of each calendar quarter.  Borrowers
authorize the Lender to debit demand deposit account number _____________ or
any other account with Lender (routing number ____________) designated in
writing by VSE, beginning September 30, 2007 for any payments due to the
Lender.  VSE further certifies that VSE holds legitimate ownership of this
account and preauthorizes this periodic debit as part of its right under said
ownership.  At the option of the Lender, the Loans shall bear interest at the
Default Rate, payable on demand, during any period of Default hereunder.

                      2.3.2	Inability to Determine Rate.
                                ----------------------------
                      In the event that the Lender shall have determined (which
determination shall be conclusive and binding upon the Borrowers) that by
reason of circumstances affecting the interbank Eurodollar market adequate and
reasonable means do not exist for ascertaining the LIBOR Rate for any given
Interest Period, the Lender shall forthwith give notice (which may be
telephonic and promptly confirmed in writing or by facsimile transmission) of
such determination to Borrowers at least two Euro-dollar Business Days prior
to, as the case may be, the conversion date of any portion of the Principal
Amount bearing interest at the Prime-based Rate to a LIBOR-based Rate.  If
such notice is given: (a) any portion of the Principal Amount bearing interest
at the Prime-based Rate that was to have been converted to a LIBOR-based Rate,
subject to the provisions hereof, shall be continued at the Prime-based Rate
and (b) any portion of the Principal Amount bearing interest at a LIBOR-based
Rate shall be converted, on the last day of the then current Interest Period
with respect thereto, to the Prime-based Rate.  Until such notice has been
withdrawn by the Lender, the Borrowers shall not have the right to have a
LIBOR-based Rate apply to any portion of the Principal Amount.

                      2.3.3	Indemnity.
                                ----------
                      The Borrowers agree to indemnify and reimburse the Lender
and to hold the Lender harmless from any loss, cost (including administrative
costs) or expense which any one or more of the Lender may sustain or incur as
a consequence of (a) a default by the Borrowers in payment when due of the
principal amount of or interest on any LIBOR Amount, (b) the failure of the
Borrowers to make, or convert the Applicable Interest Rate of, a Loan after
the Borrowers have given a Rate Request, (c) the failure of the Borrowers to
make any prepayment of a Loan after the Borrowers have given notice of such
intention to make such a prepayment, and/or (d) the making by the Borrowers of
a prepayment of a Loan on a day which is not the last day of the Interest
Period for such LIBOR Amount, calculated as provided in the following
paragraph.  This agreement and covenant of the Borrowers shall survive
termination or expiration of this Agreement and payment of the other
Obligations.

                      Contemporaneously with any prepayment of principal of a
LIBOR Amount, a prepayment fee shall be due and payable to the Lender in an
amount equal to the product of

  (A) the amount so prepaid

   multiplied by
   -------------
  (B) the difference (but not less than zero) of
      --------------
      (i) the constant maturity 360-day interest yield (as of the
      first day of the then effective Interest Period and
      expressed as a decimal) for a United States Treasury bill,
      note, or bond (a "Treasury obligation") selected by the
      Lender, in an aggregate amount comparable to the amount
      prepaid, and having, as of the first day of the then
      effective Interest Period, a remaining term approximately
      equal to the original Interest Period,

   minus
   -----

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

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

  (C) the quotient of
      ------------
      (y) the number of calendar days in the unexpired portion of
      the Interest Period,

  divided by
  ----------
      (x) 360.

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

                      2.3.4	Payment of Interest.
                                --------------------
                      Unpaid and accrued interest on each LIBOR Loan shall be
paid (a) on the earlier of (i) the last Business Day of each Interest Period for
such LIBOR Amount and (ii) three (3) months from the date of the LIBOR Amount
and (b) at maturity (whether by acceleration, declaration, extension or
otherwise); provided, however that any and all unpaid and accrued interest on
any LIBOR Amount prepaid prior to expiration of the then current Interest
Period for such LIBOR Amount shall be paid immediately upon prepayment.

       Section 2.4    General Financing Provisions.
                      -----------------------------
                      2.4.1	Borrowers' Representatives.
                                ---------------------------
                      The Borrowers hereby represent and warrant to the Lender
that each of them will derive benefits, directly and indirectly, from each
Letter of Credit and from each Loan, 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) this financing is enabling any Permitted Acquisition, (b)
the terms of the consolidated financing provided under this Agreement are more
favorable than would otherwise would be obtainable by the Borrowers
individually, and (c) 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 benefits of Letters of Credit and the proceeds of Loans;
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 VSE 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 VSE or in the name of the
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 VSE may so
elect from time to time, including, without limitation, actions to (i) request
advances under the Loans, apply for and direct the benefits of Letters of
Credits, and direct the Lender to disburse or credit the proceeds of any Loan
directly to an account of VSE, any one or more of the Borrowers or otherwise,
which direction shall evidence the making of such Loan and shall constitute
the acknowledgment by each of the Borrowers of the receipt of the proceeds of
such Loan or 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, 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 VSE.  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 VSE's duly authorized officer, officers or other Person or
Persons designated by VSE to act from time to time on behalf of VSE.

                      Each of the Borrowers hereby irrevocably authorizes each
of the Lender to make Loans to any one or more of the Borrowers, and to issue or
cause to be issued Letters of Credit for the account of any or all of the
Borrowers, 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 a Borrower under the provisions of the most
recent certificate of corporate resolutions and/or incumbency of the Borrowers
on file with the Lender and also upon the written, oral or telephone request
of any one of the Persons who is from time to time a Responsible Officer of
VSE under the provisions of the most recent certificate of corporate
resolutions and/or incumbency for VSE on file with the Lender.

                      The Lender assumes no responsibility or liability for any
errors, mistakes, and/or discrepancies 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 Loans 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
themselves 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 2.4.9 (Guaranty)) shall be limited to an aggregate amount
(after giving effect to any collections from, rights to receive contribution
from or payments made by or on behalf of any other Borrower in respect of the
Obligations) which, together with other amounts owing by such Borrowers to the
Lender under the Obligations, is equal to the largest amount that would not be
subject to avoidance under the Bankruptcy Code or any applicable provisions of
any applicable, comparable state or other Laws.

                      2.4.2	Use of Proceeds of the Loans.
                                -----------------------------
                      The proceeds of each advance under the Loans 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 Loans promptly.

                      2.4.3	Field Examination Fees.
                                -----------------------
                      The Borrower shall pay to the Lender a field examination
fee (collectively, the "Field Examination Fees" and individually a "Field
Examination Fee"), which Field Examination Fees shall be payable at the time
of each field examination of the Borrowers' books and records in an amount
prior to an Event of Default, not to exceed the Lender's actual costs of
obtaining such field audit.

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

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

                      2.4.6	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.

                      2.4.7	Liens; Setoff.
                                --------------
                      The Borrowers hereby grant to the Lender a continuing Lien
for all of the Obligations upon 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 (including,
without limitation, the 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.

                      2.4.8	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 in the interpretation or
application thereof or (c) compliance by the Lender or any corporation
controlling the Lender with any request or directive regarding any capital
adequacy (whether or not having the force of law) from any central bank or
Governmental Authority, does or shall have the effect of reducing the rate of
return on the capital of the Lender or any corporation controlling the Lender,
as a consequence of the obligations of the Lender hereunder to a level below
that which the Lender or any corporation controlling the Lender would have
achieved but for such adoption, change or compliance (taking into
consideration the policies of the Lender and the corporation controlling the
Lender, with respect to capital adequacy) by an amount deemed by the Lender to
be material, then from time to time, after submission by the Lender to the
Borrowers of a written request therefor and a statement of the basis for such
determination, the Borrowers shall pay to the Lender such additional amount or
amounts in order to compensate for such reduction.

                      2.4.9  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 2.4.9 shall be absolute and
unconditional and joint and several, irrespective of the genuineness, validity,
priority, regularity or enforceability of this Agreement, any of the Notes or
any of the Financing Documents or any other circumstance which might otherwise
constitute a legal or equitable discharge of a surety or guarantor.  Each
Borrower in its capacity as a guarantor expressly agrees that the Lender may,
in their 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 Loan 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 this
 Agreement or any of the other Financing Documents;

                                 (viii)	assign, pledge, hypothecate or otherwise

Borrower, as guarantor under this Section 2.4.9, 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 or their remedies against the Borrowers or the Collateral either
before, concurrently with or after pursuing or enforcing its rights and

proceedings may be brought against each Borrower under this Section 2.4.9,
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 2.4.9, 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 2.4.9 in any manner whatsoever, and this Section 2.4.9 shall remain
and continue in full force and effect.  It is the intent and purpose of this
Section 2.4.9 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 2.4.9, 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 2.4.9, 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
2.4.9 and of presentment, demand and protest thereof;

                                 (iv)	notice of any increase in the amount
of any portion of or all of the indebtedness guaranteed by
this Section 2.4.9;

                                 (v)	demand for observance, performance
or enforcement of any of the terms or provisions of this
Section 2.4.9, 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 2.4.9, except errors
and omissions resulting from acts of bad faith;

                               (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.
                      Within ten (10) days following any request of the Lender
so to do, each Borrower will furnish the Lender and such other persons as the
Lender may direct with a written certificate, duly acknowledged stating in
detail whether or not any credits, offsets or defenses exist with respect to
this Section 2.4.9.

                      The Borrowers may request and the Lender or its Affiliates
may, in their sole and absolute discretion, provide ACH Transactions and Swap
Transactions although the Borrowers are not required to do so.  In the event
the Borrowers request the Lender or its Affiliates to procure ACH Transactions
or Swap Transactions, then the Borrowers agree to indemnify and hold the
Lender or its affiliates harmless from any and all obligations now or
hereafter owing to the or its affiliates.  The Borrowers agree to pay the
Lender or its Affiliates all amounts owing to the Lender or its Affiliates
pursuant to ACH Transactions and Swap 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 Loan,
which advance shall be deemed to have been requested by the Borrowers.  The
Borrowers acknowledge and agree that the obtaining of ACH Transactions and
Swap 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.

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

contemplated by the Financing Documents which materially and adversely affects
or in the future could, in the reasonable opinion of that Borrower materially

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 4.1.9 (Financial
Condition), and are now, adequately provided for on the books of the Borrowers
and its Subsidiaries, as appropriate.  No tax liability has been asserted by

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 Lender evidencing the storage of Inventory and the interests of the Lender
therein; (d) permit the Lender and its agents or representatives to inspect

shall be sufficient to satisfy for all purposes the requirements of a
financing statement as set forth in Article 9 of the applicable Uniform
Commercial Code.  Each Borrower hereby irrevocably appoints the Lender as the
Borrower's attorney-in-fact, with power of substitution, in the name of the
Lender or in the name of the Borrower or otherwise, for the use and benefit of
the Lender, but at the cost and expense of the Borrowers and without notice to
the Borrowers, to execute and deliver any and all of the instruments and other
documents and take any action which the Lender may require pursuant the
foregoing provisions of this Section 6.1.23.

Subsidiaries to notify the Lender not less than thirty (30) days prior to (a)

conducts its business, (b) any change of the location of the chief executive

transfer its principal place of business or the office where it keeps its
records pertaining to the Collateral, upon the Lender's request the Borrowers
will provide to the Lender a subsequent opinion of counsel as to the filing,
recording and other requirements with which the Borrowers and their
Subsidiaries have complied to maintain the Lien and security interest in favor
of the Lender in the Collateral.

                      6.1.26	Use of Premises and Equipment.
                                ------------------------------
                      The Borrowers agree that until the Obligations are fully
paid and all of the Revolving Credit Commitments and the Letters of Credit
have 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 Collateral is located, and may
proceed over and through any of the Borrowers' owned or leased property.

                      6.1.27	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.

or any of the Financing Documents shall for any reason (except to the extent
permitted by its express terms) cease to be effective or to create a valid and
perfected first priority Lien (except for Permitted Liens) on, or security
interest in, any of the Collateral purported to be covered thereby.

                      7.1.13	Collateral Inadequacy.

subcontract in question is less than $500,000.

       Section 7.2	Remedies.
                        ---------
       Upon the occurrence of any Event of Default, the Lender may, in the
exercise of its sole and absolute discretion from time to time, and shall, at
any time thereafter exercise any one or more of the following rights, powers
or remedies.

                      7.2.1	Acceleration.
                                -------------
                      The Lender may 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 Commitments, under this
Agreement and/or under any of the other Financing Documents.  Further, upon
the occurrence of an Event of Default or Default specified in Sections 7.1.5
(Receiver; Bankruptcy) or 7.1.6 (Involuntary Bankruptcy, etc.), the Revolving
Credit Commitments and any agreement in any of the Financing Documents to
provide additional credit and/or to 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 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 consisting of securities restrict the prospective bidders or
purchasers as to their number, nature of business and investment intention,
including, without limitation, a requirement that the Persons making such
purchases represent and agree to the satisfaction of the Lender that they are
purchasing such securities for their account, for investment, and not with a
view to the distribution or resale of any thereof.  The Borrowers covenant and
agree to do or cause to be done promptly all such acts and things as the
Lender may request from time to time and as may be necessary to offer and/or
sell the securities or any part thereof in a manner which is valid and binding
and in conformance with all applicable Laws.  Upon any such sale or
disposition, the Lender shall have the right to deliver, assign and transfer
to the purchaser thereof the Collateral consisting of securities so sold.

                      7.2.4	Specific Rights With Regard to Collateral.
                                ------------------------------------------
                      In addition to all other rights and remedies provided
hereunder or as shall exist at law or in equity from time to time, the Lender
may (but shall be under no obligation to), without notice to any of the
Borrowers, and each Borrower hereby irrevocably appoints the Lender as its
attorney-in-fact, with power of substitution, in the name of the Lender and/or
in the name of any or all of the Borrowers or otherwise, for the use and
benefit of the Lender, but at the cost and expense of the Borrowers and
without notice to the Borrowers:

                      (a)	request any Account Debtor obligated on
any of the Accounts to make payments thereon directly to the
Lender, with the Lender taking control of the Proceeds thereof;
                      (b)	compromise, extend or renew any of the
Collateral or deal with the same as it may deem advisable;
                      (c)	make exchanges, substitutions or
surrenders of all or any part of the Collateral;
                      (d)	copy, transcribe, or remove from any place
of business of any Borrower or any Subsidiary all books, records,
ledger sheets, correspondence, invoices and documents, relating to
or evidencing any of the Collateral or without cost or expense to
the Lender, make such use of any Borrower's or any Subsidiary's
place(s) of business as may be reasonably necessary to administer,
control and collect the Collateral;
                      (e)	repair, alter or supply goods if necessary
to fulfill in whole or in part the purchase order of any Account
Debtor;
                      (f)	demand, collect, receipt for and give
renewals, extensions, discharges and releases of any of the
Collateral;
                      (g)	institute and prosecute legal and
equitable proceedings to enforce collection of, or realize upon,
any of the Collateral;
                      (h)	settle, renew, extend, compromise,
compound, exchange or adjust claims in respect of any of the
Collateral or any legal proceedings brought in respect thereof;
                      (i)	endorse or sign the name of any Borrower
upon any Items of Payment, certificates of title, Instruments,
Investment Property, stock powers, documents, documents of title,
financing statements, assignments, notices or other writing
relating to or part of the Collateral and on any proof of claim in
bankruptcy against an Account Debtor;
                      (j)	clear Inventory through customs in the
Lender's or any Borrower's name and to sign and deliver to customs
officials powers of attorney in any Borrower's name for such
purpose;
                      (k)	notify the Post Office authorities to
change the address for the delivery of mail to the Borrowers to
such address or Post Office Box as the Lender may designate and
receive and open all mail addressed to any of the Borrowers; and
                      (l)	take any other action necessary or
beneficial to realize upon or dispose of the Collateral or to
carry out the terms of this Agreement.

                      7.2.5	Application of Proceeds.
                                ------------------------
                      Any proceeds of sale or other disposition of the
Collateral will be applied by the Lender to the payment first to 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 shall 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, or in the name of any or all
of the Borrowers or otherwise, for the use and benefit of the Lender, but at
the cost and expense of the Borrowers and without notice to the Borrowers.
All sums so paid or advanced by the Lender together with interest thereon from
the date of payment, advance or incurring until paid in full at the Post-
Default Rate and all costs and expenses, shall be deemed part of the
Enforcement Costs, shall be paid by the Borrowers to the Lender on demand, and
shall constitute and become a part of the Obligations.

                      7.2.7	Other Remedies.
                                ---------------
                      The Lender may from time to time proceed to protect or
enforce its rights 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.

writing signed by the Lender and the Borrowers.  No waiver of any provision of

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.  Without limiting the generality of the foregoing
and subject to the terms of this Agreement, the Lender may:

                      (a)	proceed against any one or more of the
Borrowers with or without proceeding against any other Person
(including, without limitation, any one or more of the Guarantors)
who may be liable (by endorsement, guaranty, indemnity or
otherwise) for all or any part of the Obligations;

                      (b)	proceed against any one or more of the
Borrowers with or without proceeding under any of the other
Financing Documents or against any Collateral or other collateral

obligation of the Borrowers and without notice, release or
compromise with any guarantor or other Person liable for all or
any part of the Obligations under the Financing Documents or
otherwise;

                      (d)	without reducing or impairing the
obligations of the Borrowers and without notice thereof:

                          (i)	fail to perfect the Lien in any or
all Collateral or to release any or all the Collateral or to

Obligations.

       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	Successors and Assigns.
                        -----------------------

interest herein without the prior written consent of Lender.

       Section 8.6	Continuing Agreements.
                        ----------------------
       All covenants, agreements, representations and warranties made by the
Borrowers in this Agreement, in any of the other Financing Documents, and in
any certificate delivered pursuant hereto or thereto shall survive the making
by the Lender of the Loans, the issuance of Letters of Credit by the Lender
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 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 or its agents and others, or to the
extent there are, the same are waived and released.

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

Costs, 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 Rate. Enforcement Costs shall be immediately due and payable at the
time advanced or incurred, whichever is earlier.  Without implying any
limitation on the foregoing, the Borrowers agree, as part of the Enforcement
Costs, to pay upon demand any and all stamp and other Taxes and fees payable
or determined to be payable in connection with the execution and delivery of
this Agreement and the other Financing Documents and to save the Lender
harmless from and against any and all liabilities with respect to or resulting
from any delay in paying or omission to pay any Taxes or fees referred to in
this Section.  The provisions of this Section shall survive the execution and
delivery of this Agreement, the repayment of the other Obligations and shall
survive the termination of this Agreement.

       Section 8.8	Applicable Law; Jurisdiction.
                        -----------------------------
                      8.8.1	Applicable Law.
                                ---------------
                      As a material inducement to the Lender to enter into this
Agreement, each of the Borrowers acknowledges and agrees 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.

                      8.8.2	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.
