                            THE CREDIT FACILITIES

        Section 2.1   The Revolving Credit Facility.

                      2.1.1   Revolving Credit Facility.

unpaid principal balance of the Revolving Loan exceeds the Revolving Credit
Committed Amount in effect from time to time, the Borrower shall pay such
excess to the Lender ON DEMAND.

                      During the Revolving Credit Commitment Period, the
Borrower may request advances under the Revolving Credit Facility in
accordance with the provisions of this Agreement; provided that after giving
effect to the Borrower's request the aggregate outstanding principal balance
of the Revolving Loan and all Letter of Credit Obligations would not exceed
the lesser of (a) the Revolving Credit Committed Amount or (b) 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 Loan; Lender Protection Loans.

                      The Borrower 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 the Borrower with the Lender (or an
Affiliate of the Lender) or shall be otherwise applied as directed by the
Borrower, which direction the Lender may require to be in writing. Not later
than 12:00 noon. (Eastern Time) on the date of the requested borrowing, the
Borrower 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 Borrower
within three (3) Business Days after the making of the requested advance under
the Revolving Loan. Each Loan Notice shall be irrevocable.

                      In addition, the Borrower hereby irrevocably authorizes
the Lender at any time and from time to time, without further request from or
notice to the Borrower, to make advances under the Revolving Loan, 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 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

                                      18
<PAGE>

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 reserve hereunder exceeds the 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 aggregate of (a) ninety percent
(90%) of the amount of Eligible Receivables derived from Government Contracts,
(b) eighty percent (80%) of the amount of Eligible Receivables derived from
contracts other than Government Contracts approved by the Lender, (c) ninety
percent (90%) of the Borrower's foreign Eligible Receivables that are
supported by a letter of credit from a financial institution acceptable to the
Lender and (d) one hundred percent (100%) of cash held in restricted accounts
as advance payments and secured by letters of credit.

                      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 Borrower fails 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 its 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
Borrower, 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 Borrower existing on or about the
Closing Date and upon information and records furnished to the Lender by the
Borrower. If at any time or from time to time hereafter, the business
operations of the Borrower change or such information and records furnished to
the Lender is materially 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 Borrower from time to time either
orally or in writing.

                      2.1.4   Borrowing Base Report.

                      The Borrower will furnish to the Lender a report of the
Borrowing Base (each a "Borrowing Base Report"; collectively, the "Borrowing
Base Reports") in the form

                                      19
<PAGE>

attached hereto as EXHIBIT C and made a part hereof or such other form as may
be required from time to time by the Lender, appropriately completed and duly
signed as follows: (a) if any sum is outstanding under the Revolving Loan or
any Letter of Credit is outstanding, not later than the twentieth (20th) day
after the end of each month and at such other times as may be reasonably
requested by the Lender and (b) if there is no sum outstanding under the
Revolving Loan and no Letter of Credit is outstanding, not later than the
forty fifth (45th) day after the end of each calendar quarter and at such
other times as may be reasonably requested by the Lender. The Borrowing Base
Report shall contain 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. Upon the Lender's request upon the creation of any Receivables or at
such other intervals as the Lender may require, the Borrower will provide the
Lender with: (a) confirmatory assignment schedules; (b) copies of Account
Debtor invoices; (c) such further schedules, documents and/or information
regarding any of 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 (or by
any other officers or employees of the Borrower whom a Responsible Officer
from time to time authorizes in writing to do so), and delivered to the Lender
from time to time solely for the Lender's convenience in maintaining records
of the Collateral. The failure of the Borrower to deliver any such items to
the Lender shall not affect, terminate, modify, or otherwise limit the Liens
of the Lender on the Collateral.

                      2.1.5   Revolving Credit Note.

                      The obligation of the Borrower 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 "A" 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
Borrower acknowledges and agrees that, if the outstanding principal balance of
the Revolving Loan outstanding from time to time exceeds the face amount of
the Revolving Credit Note, the excess shall bear interest at the Post-Default
Rate for the Revolving Loan and shall be payable, with accrued interest, ON
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 Loan.

                      The Borrower 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.

                                      20
<PAGE>

                      2.1.7   Optional Prepayments of Revolving Loan.

                      The Borrower 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.

                      The Borrower 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 Borrower where
necessary to permit the collection of any such Items of Payment, the Borrower
hereby agreeing to make such endorsement. In the event the Borrower fails to
do so, the Lender is hereby authorized by the Borrower to make the endorsement
in the name of the Borrower. Prior to such a deposit, the Borrower will not
commingle any Items of Payment with any of the Borrower's 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 Borrower
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.

                      The Borrower hereby authorizes the Lender to inspect all
Items of Payment, endorse all Items of Payment in the name of the Borrower,
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 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 that are not proceeds of Accounts or
after a Default or Event of Default, against any of the Obligations) or credit
such collected funds to a depository account of the Borrower with the Lender
(or an Affiliate of the Lender), the order and method of such application to
be in the reasonable 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 of the Revolving Loan made by the
Lender hereunder as of the date made, (ii) the

                                      21
<PAGE>

amount of any interest accrued on the Revolving Loan as and when due, and
(iii) any other amounts due and payable by the Borrower 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 Borrower to the Lender on account of
the Revolving Loan 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. 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
Borrower in all respects, absent manifest error, unless the Lender receives
specific written objection thereto from the Borrower within thirty (30)
Business Days after such statement or reconciliation shall have been received
by the Borrower.

                      2.1.10  Revolving Credit Unused Line Fee.

                      The Borrower shall pay to the Lender a quarterly
revolving credit facility fee (collectively, the "Revolving Credit Unused Line
Fees" and individually, a "Revolving Credit Unused Line Fee") in an amount
equal to one quarter of one percent (1/4%) per 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
the Borrower to the Lender on the first day of each calendar quarter,
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, the Borrower, upon the prior
approval of the Lender, may obtain standby or commercial letters of credit (as
the same may from time to time be amended, supplemented or otherwise modified,
each a "Letter of Credit" and collectively the "Letters of Credit") from the
Lender from time to time from the Closing Date until the Business Day
preceding the Revolving Credit Termination Date. The Borrower will not be
entitled to obtain a Letter of Credit hereunder unless after giving effect to
the request, the outstanding principal balance of the Revolving Loan and of
the Letter of Credit Obligations would not exceed the lesser of (i) the
Revolving Credit Committed Amount, or (ii) the most current Borrowing Base.

                      2.2.2   Letter of Credit Fees.

                      Prior to or simultaneously with the opening of each
Letter of Credit, the Borrower 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 face amount of the
Letter of Credit. 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 Borrower shall pay to the Lender any and all additional issuance,
negotiation, processing, transfer or other

                                      22
<PAGE>

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 Borrower under the
provisions of this Agreement and are a part of the Obligations. Subsequent to
an Event of Default, the Letter of Credit Fee shall be increased to three
percent (3%) per annum of the 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 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 Borrower, the Lender shall make advances under the Revolving Loan for
the account of the Borrower 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 Borrower hereby assigns, pledges,
grants and sets 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 Borrower acknowledges and agrees
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 Borrower
or the Lender. The Borrower further acknowledges and agrees 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 Borrower's
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.

                      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 Borrower in full in accordance with Section 2.2.5 (Payments
of Letters of Credit) and the Letter

                                      23
<PAGE>

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

                      2.2.5   Payments of Letters of Credit.

                      The Borrower hereby promises 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 Borrower 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 annum equal to the then
        current highest rate of interest on the Revolving Loan.

                      In addition, the Borrower hereby promises 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 Borrower 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 Borrower 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

                                      24
<PAGE>

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 Borrower for any Letter
of Credit Obligations, in bankruptcy or otherwise; provided, however, that the
Borrower 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 Borrower 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 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 Lender of funding any obligation under or in connection with
the Letter of Credit, then, upon demand by the Lender, the Borrower shall
immediately pay to the Lender from time to time as specified by the Lender,
additional amounts which shall be sufficient to compensate the Lender for such
increased cost, together with interest on each such amount from the date
demanded until payment in full thereof at a rate per annum equal to the then
highest current rate of interest on the Revolving Loan. A certificate as to
such increased cost incurred by the Lender, submitted by the Lender to the
Borrower, shall be conclusive, absent manifest error.

                      2.2.7   General Letter of Credit Provisions.

                      The Borrower hereby instructs the Lender to pay any
draft complying with the terms of any Letter of Credit irrespective of any
instructions of the Borrower to the contrary. The Borrower assumes 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 Borrower hereby
indemnifies and holds 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 Borrower to perform the agreements
hereunder and under any Letter of Credit

                                      25
<PAGE>

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 Borrower, (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 Borrower 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 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
Borrower shall reimburse the Lender, as appropriate, for any such payment
pursuant to provisions of Section 2.2.5 (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   Borrower's Representatives.

                      The Borrower hereby irrevocably authorizes the Lender to
make Loans, and issue or cause to be issued Letters of Credit for the account
of the Borrower, 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 Borrower under the provisions
of the most recent certificate of corporate resolutions and/or incumbency of
the Borrower on file

                                      26
<PAGE>

with the Lender or who is an officer or employee of the Borrower whom a
Responsible Officer from time to time authorizes in writing to do so. The
Lender does not and shall not assume any 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 Borrower in connection with the Credit Facilities,
any Loan , any Letter of Credit or any other transaction in connection with
the provisions of this Agreement.

                      2.3.2   Use of Proceeds of the Loan.

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

                      2.3.3   Administrative Fees.

                      The Borrower shall pay to the Lender a quarterly
administrative fee (each an "Administrative Fee" and collectively, the
"Administrative Fees") for administrative services performed in conjunction
with the Revolving Credit Facility. The quarterly Administrative Fee shall be
$3,750 and shall be payable each quarter, in advance, on the first (1st) day
of each March, June, September and December until the Revolving Credit
Termination Date.

                      2.3.4   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.

                      2.3.5   Payments.

                      All payments of the Obligations, including, without
limitation, principal, interest, Prepayments, and Fees, shall be paid by the
Borrower without setoff, recoupment or counterclaim to the Lender in
immediately available funds not later than 12:00 p.m. (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 to the Lender's principal office in
McLean, Virginia or at such other location as the Lender may at any time and
from time to time notify the Borrower. Alternatively, at its sole discretion,
the Lender may charge any deposit account of the Borrower 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 Borrower shall have not otherwise tendered payment to the Lender. All

                      2.3.6   Liens; Setoff.

                      The Borrower hereby grants 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 Borrower 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 account of,
the Borrower, and also upon any and all deposit accounts (general or special)
and credits of the Borrower, if any, with the Lender or any Affiliate of the
Lender, at any time existing, excluding any deposit accounts held by the
Borrower in its capacity as trustee for Persons who are not Affiliates of the
Borrower. 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 Borrower at any
time and from time to time, without notice to the Borrower, 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.

                      2.3.7   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 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,
in its discretion, to be material, then from time to time, after submission by
the Lender to the Borrower of a written request therefore and a statement of
the basis for such determination, the Borrower shall pay to the Lender such
additional amount or amounts in order to compensate the Lender or its
controlling corporation for any such reduction.

                      2.3.8   ACH Transactions and Swap Contracts.

                      The Borrower may request and the Lender or its
affiliates may, in their sole and absolute discretion, provide ACH
Transactions and Swap Contracts. In the event the Borrower requests Lender or
its affiliates to procure ACH Transactions or Swap Contracts, then the
Borrower agrees to indemnify and hold the Lender or its affiliates harmless
from any and all obligations now or hereafter owing to the Lender or its
affiliates. The Borrower agrees to pay the Lender or its affiliates all
amounts owing to the Lender or its affiliates pursuant to ACH Transactions and
Swap Contracts. In the event the Borrower 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 Borrower. The Borrower acknowledges and agrees that the obtaining of
ACH Transactions and Swap Contracts 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.

<PAGE>

Applicable Interest Rate or Applicable Interest Rates for any Loans or may
convert the Applicable Interest Rate, for any existing Loan to any other
Applicable Interest Rate.

                              (c)    The Borrower's selection of an Applicable
Interest Rate, the Borrower's election to convert an Applicable Interest Rate

rate are subject to the following limitations:

                                     (i)     no change from the Eurodollar
        Rate to the Base Rate shall become effective on a day other than a

        payment on account of such Loan is scheduled to be paid shall be made
        only after such payment shall have been made;

                                     (iii)   no more than three (3) different
        Eurodollar Rates may be outstanding at any time and from time to time

        selection, there shall not exist a Default or an Event of Default; and

                                     (v)     the minimum principal amount of a
        Eurodollar Loan shall be One Hundred Thousand Dollars ($100,000).

                              (d)    If a request for an advance under the

otherwise include a selection of an Applicable Interest Rate, or if, after
having made a selection of an Applicable Interest Rate, the Borrower fails or

subject to, the provisions of this Section.

                             (e)     The Lender will not be obligated to make

Borrower specifying the following information:

                                     (i)   the amount to be borrowed or
        converted;

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

        election is to be effective.

                      Any telephonic notice must be confirmed in writing
within three (3) Business Days. Each Interest Rate Election Notice must be
received by the Lender not later than 10:00 a.m. (Eastern Time) on the
Business Day of any requested borrowing or conversion in the

                                      30
<PAGE>

case of a selection of the Base Rate and not later than 10:00 a.m. (Eastern

borrowing or conversion in the case of a selection of the Eurodollar Rate.

                      2.4.3   Inability to Determine Eurodollar Base Rate.

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

                      2.4.4   Payment of Interest.

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

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

Subsidiaries is in default under or with respect to any obligation under any
existing mortgage, indenture, contract or agreement binding on it or affecting

adversely affects or in the future could, in the reasonable opinion of the

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 the Borrower, such Taxes are not the subject of any Liens other
than Permitted Liens, and adequate reserves therefore have been established as
required under GAAP. All tax liabilities of the Borrower 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 Borrower
and its Subsidiaries, as appropriate. No tax liability has been asserted by

operations, the Borrower's financial condition, or the value of, or the
ability of the Lender to realize upon, the Collateral.

                      6.1.6   Preservation of Properties.

ERISA or the Internal Revenue Code, which results, or may result, in any
material liability of the Borrower, or (b) any Reportable Event if, upon
termination of the plan or plans with respect to which one or more such
Reportable Events shall have occurred, there is or would be any material
liability of the Borrower to the PBGC. Upon the Lender's request, the Borrower

specific endorsement to each such insurance policy pursuant to which the

that, notwithstanding the means of attachment, no goods of the Borrower
hereafter attached to any realty shall be deemed a fixture, which declaration
shall be irrevocable, without the Lender's consent, until all of the
Obligations have been paid in full and all of the Commitments and Letters of
Credit have been terminated.

formalities as the Lender may require, in order to create and maintain a valid

                      7.2.1   Acceleration.

                      The Lender may declare 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 Borrower hereby waives.

                      7.2.2   Further Advances.

                      The Lender may from time to time without notice to the
Borrower suspend, terminate or limit any further loans or other extensions of
credit under this Agreement and under any of the other Financing Documents.
Further, upon the occurrence of an Event of Default or Default specified in
Section 7.1.5 (Receiver; Bankruptcy) or Section 7.1.6 (Involuntary Bankruptcy,
etc.), the Revolving Credit Commitment 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 Borrower.

                      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 Borrower 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 the 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 Borrower at the address set forth in
Section 8.1 (Notices), or such other address of the Borrower 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 Borrower. 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 Borrower agrees 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 Borrower recognizes 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

                                      60
<PAGE>

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 Borrower covenants and
agrees 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 the Borrower, and
the 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
the Borrower or otherwise, for the use and benefit of the Lender, but at the
cost and expense of the Borrower and without notice to the Borrower:

                              (a)     request any Account Debtor obligated on

        surrenders of all or any part of the Collateral;

                              (d)     copy, transcribe, or remove from any
        place of business of the 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 the Borrower's or any
        Subsidiary's place(s) of business as may be reasonably necessary to
        administer, control and collect the Collateral;

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

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

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

                                      61
<PAGE>

                              (h)     endorse or sign the name of the 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;

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

                              (j)     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 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 shall determine. If the
sale or other disposition of the Collateral fails to fully satisfy the
Obligations, the Borrower shall remain liable to the Lender for any
deficiency.

                      7.2.6   Performance by Lender.

                      Upon the occurrence and continuation of an Event of
Default, the Lender without notice to or demand upon the Borrower 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
Borrower, and may enter upon the premises of the Borrower for that purpose and
take all such action thereon as the Lender may consider necessary or
appropriate for such purpose and the Borrower 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 the Borrower or otherwise, for the use
and benefit of the Lender, but at the cost and expense of the Borrower and
without notice to the Borrower. 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 Borrower 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

                                      62
<PAGE>

Obligations all moneys, credits and other property of any nature whatsoever of
the Borrower 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.

        Section 8.2    Amendments; Waivers.

        This Agreement and the other Financing Documents may not be amended,
modified, or changed in any respect except by an agreement in writing signed
by the Lender and the Borrower. No waiver of any provision of this Agreement
or of any of the other Financing Documents, nor consent to any departure by
the Borrower therefrom, shall in any event be effective unless the same shall
be in writing signed by the Lender. No course of dealing between the Borrower
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.

        Without implying any limitation on the foregoing:

                              (a)    Any waiver or consent shall be effective
only in the specific instance, for the terms and purpose for which given,
subject to such conditions as the Lender may specify in any such instrument.

                                      63
<PAGE>

                              (b)    No waiver of any Default or Event of
Default shall extend to any subsequent or other Default or Event of Default,
or impair any right consequent thereto.

                              (c)    No notice to or demand on the Borrower in
any case shall entitle the Borrower to any other or further notice or demand
in the same, similar or other circumstance.

                              (d)    No failure or delay by the Lender to
insist upon the strict performance of any term, condition, covenant or
agreement of this Agreement or of any of the other Financing Documents, or to
exercise any right, power or remedy consequent upon a breach thereof, shall
constitute a waiver, amendment or modification of any such term, condition,
covenant or agreement or of any such breach or preclude the Lender from
exercising any such right, power or remedy at any time or times.

                              (e)    By accepting payment after the due date
of any amount payable under this Agreement or under any of the other Financing
Documents, the Lender shall not be deemed to waive the right either to require
prompt payment when due of all other amounts payable under this Agreement or
under any of the other Financing Documents, or to declare a default for
failure to effect such prompt payment of any such other amount.

        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:

                              (d)    proceed against the Borrower with or
        without proceeding against any other Person who may be liable (by
        endorsement, guaranty, indemnity or otherwise) for all or any part of
        the Obligations;

                                     (a)     proceed against the Borrower with
        or without proceeding under any of the other Financing Documents or
        against any Collateral or other collateral and security for all or any
        part of the Obligations;

                                     (b)     without reducing or impairing the
        obligation of the Borrower 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;

                                             (i)     without reducing or
               impairing the obligations of the Borrower and without notice
               thereof:fail to perfect the Lien in any or all Collateral or to
               release any or all the Collateral or to accept substitute
               Collateral;

                                      64
<PAGE>
                                             (ii)    approve the making of
               advances under the Revolving Loan under this Agreement;

                                             (iii)   waive any provision of
               this Agreement or the other Financing Documents;

                                             (iv)    exercise or fail to
               exercise rights of set-off or other rights; or

                                     (c)     accept partial payments or extend
        from time to time the maturity of all or any part of the 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
        Borrower 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 Borrower, assign
to any Person (each an "Assignee" and collectively, the "Assignees") all or a
portion of the Lender's Commitments. The Lender and its Assignee shall notify
the Borrower in writing of the date on which the assignment is to be effective
(the "Adjustment Date"). On or before the Adjustment Date, the Lender, the
Borrower and the 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 necessary to reflect such
assignment. Upon the request of the Lender following an assignment made in
accordance with this Section 8.5, the Borrower shall issue new Notes to the
Lender and its Assignee reflecting such assignment, in exchange for the
existing Notes held by the Lender.

                                      65
<PAGE>

        In addition, notwithstanding the foregoing, the Lender may at any time
pledge all or any portion of the Lender's rights under this Agreement, any of
the Commitments 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 Commitments;
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
Borrower 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.

        In connection with any sale, transfer, assignment or participation by
the Lender in accordance with Section 8.5 (Assignments by Lender) or Section
8.6 (Participations by Lender), the Lender shall have the right to disclose to
any actual or potential purchaser, assignee, transferee or participant all
financial 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 inure to the benefit of the Borrower and the Lender and their respective
successors and assigns, except that the Borrower shall not have the right to
assign its rights hereunder or any interest herein without the prior written
consent of the Lender.

        Section 8.9    Continuing Agreements.

        All covenants, agreements, representations and warranties made by the
Borrower 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 and the
execution and delivery of the Notes, shall be binding upon the Borrower
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 Borrower 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 agents and others, or to the extent there are, the same are waived
and released.

        Section 8.10   Enforcement Costs.

        The Borrower agrees to pay to the Lender on demand all Enforcement
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 Borrower agrees, 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 8.11  Applicable Law; Jurisdiction.

                      8.11.1  Applicable Law.

                      The Borrower 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 Borrower, 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 Borrower irrevocably submits 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. The Borrower 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 Borrower and may be enforced in any court in which the
Borrower is subject to jurisdiction, by a suit upon such judgment, provided
that service of process is effected upon the Borrower 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 Borrower hereby irrevocably designates and appoints
Robert C. Bower at 8419 Terminal Road Newington, Virginia 22122, as the
Borrower's authorized agent to receive on the Borrower's 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 Borrower shall irrevocably

<PAGE>

               1.162-27(e)(3) and as a "Non-Employee Director" under Rule
               16b-3 promulgated under the Securities Exchange Act of 1934, as
               amended. The members of the Committee shall be appointed by,
               and serve at the pleasure of, the Board of Directors. A
               majority of the Committee members shall constitute a quorum and
               the acts of a majority of the members present at any meeting at
               which a quorum is present or acts approved in writing by a
               majority of the Committee, shall be valid acts of the
               Committee. All references herein to the Committee shall be
               deemed to mean any successor to the Committee, however
               designated, or the Board of Directors, if the Board of
               Directors has not appointed a Committee.

        (b)    Subject to the powers herein specifically reserved to the Board
               of Directors, the Committee shall have full power and authority
               to determine which Recipients shall receive Awards, to
               construe, interpret and administer the Plan and, subject to the
               other provisions of the Plan, to make determinations which
               shall be final, conclusive and binding upon all persons
               including, without limitation, the Company, the stockholders of
               the Company, the Board of Directors, the Recipients and any
               persons having any interest in any Awards which may be granted
               under the Plan. The Committee shall impose such additional
               conditions upon the grant and exercise of Awards under the Plan
               as may from time to time be deemed necessary or advisable, in
               the opinion of counsel to the Company, to comply with
               applicable laws and regulations. The Committee from time to
               time may adopt such rules and regulations for the carrying out
               of the Plan and written policies for implementation of the
               Plan. Such policies may include, but need not be limited to,
               the type, size and terms of Awards to be made to Recipients and
               the conditions for payment of such Awards. Notwithstanding the
               foregoing, the Board of Directors shall have authority to
               determine which Directors shall receive Awards and the terms
               and conditions of such Awards. In addition, the Committee may
               delegate to the Chief Executive Officer of the Company the
               authority to grant Awards to Recipients who are not subject to
               Section 16(a) of the Securities Exchange Act of 1934, as
               amended.

        (c)    The payment under any Target Award shall be contingent upon the
               attainment of one or more pre-established performance goals
               established by the  Committee in writing within ninety (90)
               days of the commencement of the Target Award Performance Period
               (or in the case of a newly hired Recipient, before 25% of such
               Recipient's service for such Target Award Performance Period
               has elapsed).  Such performance goals will be based upon one or
               more of the following performance-based criteria: earnings per
               share of the Common Stock, the Company's return on net assets,
               equity, or revenues, or the Company's cash flow, book value,
               Common Stock performance or price-earnings ratio. The
               Committee, in its discretion, may cancel or decrease an earned
               Target Award, but, except as otherwise permitted by Treasury
               Regulation Section 1.162-27(e)(2)(iii)(C), may not, under any
               circumstances, increase such award.

                                      3

4.      Eligibility.

        Awards may be granted to any Recipient; provided, that Incentive Stock
Options may only be granted to employees of the Company or a Subsidiary in
which the Company owns, directly or indirectly, stock possessing 50% or more
of the total combined voting power of such Subsidiary (or such other level of
stock ownership as may from time to time be set forth in Section 424(c) of the
Internal Revenue Code). No member of the Committee (other than an ex officio
member) shall be eligible for grants of Awards under the Plan by the
Committee, although such member may be eligible for grants of Director Stock
Options or for Awards granted by the Board of Directors.

5.      Stock Subject to the Plan.

        (a)    The total number of shares of Common Stock issuable under this
               Plan may not exceed an aggregate of 650,000 shares plus the
               number of shares available under the 1995 Amended and Restated
               Stock Incentive Plan subject to adjustment pursuant to Section
               15 pertaining to a change in capital structure, and subject to
               increase as provided in Section 5.  Shares of Common Stock to
               be delivered or purchased under the Plan may be either
               authorized but unissued Common Stock or treasury shares. All of
               such shares may be issued or issuable under this Plan in
               connection with the exercise of  Incentive Stock Options,
               provided that not more than 650,000 shares plus the number of
               shares available under the 1995 Amended and Restated Stock
               Incentive Plan may used to grant Incentive Stock Options
               subject to adjustment pursuant to Section 15 pertaining to a
               change in capital structure, and subject to increase as
               provided in Section 5.

        (b)    Shares of Common Stock reserved for issuance pursuant to
               previously granted Awards or Director Stock Options which are
               not actually issued pursuant to such Award or Director Stock
               Option pursuant to this Plan (due to forfeiture, cancellation,
               lapse, surrender, payment of withholding taxes or otherwise)
               shall be available for future Awards or Director Stock Options.

        (c)    Shares of Common Stock reserved for issuance pursuant to
               previously granted stock options under any other plan of the
               Company for the benefit of employees or Directors which has
               been approved by the stockholders of the Company, and which are
               not actually issued pursuant to such stock option (due to
               forfeiture, cancellation, lapse, surrender, payment of
               withholding taxes or otherwise) shall be available for future
               Awards or Director Stock Options.

6.      Awards.

        (a)    Awards under the Plan may include shares of Common Stock,
               Restricted Shares, Stock Options, Performance Shares,
               Performance Units, and Target Awards.

        (b)    The Committee may establish performance goals to be achieved
               within such Performance Periods as may be selected by it using
               such measures of the

                                      4
<PAGE>

               performance of the Company it may select as a condition to the
               receipt of the Award.

7.      Vesting Requirements and Other Contingencies.

        The Committee may determine that all or a portion of an Award or a
payment to a Recipient pursuant to an Award, in any form whatsoever, shall be
vested at such times and upon such terms as may be selected by it, except that
(i) an award of Restricted Shares shall not vest prior to the expiration of
three (3) years from the date of grant, and (ii) all other Awards may not vest
in less than one year from the date of grant (unless such Award was granted to
a Recipient in lieu of cash compensation due to such Recipient). However, the
Committee may accelerate the vesting of any Award upon a "Change of Control of
the Company" as such term may be defined in the Award agreement. In addition,
the Committee may require a Recipient to refund to the Company the value of an
Award realized by a Recipient, if the Recipient accepts employment with a
competitor of the Company or a subsidiary of the Company within six (6) months
of such realization. In the case of a Stock Option, a Recipient shall be
deemed to realize its value upon the exercise of the Stock Option and its
value shall be an amount equal to the excess of the market value of the shares
of Common Stock received as of the date of the exercise over the exercise
price paid for such shares. In the case of all other Awards, a Recipient shall
be deemed to realize their value upon the payment of the Award and its value
shall be the amount of any cash received plus an amount equal to the market
value of the shares of Common Stock received in connection with the Award. The
market value of shares shall be the closing price for the Common Stock on the
NASDAQ Exchange (or on the principal securities exchange or other market on
which the Common Stock is then being traded) on the date of realization, or if
such closing price is not reported on such date, the last reported closing
price.

8.      Deferred Payment.

        The Committee, or in the case of Awards to Outside Directors, the
Board of Directors, may determine that the receipt of all or a portion of an
Award or a payment to a Recipient pursuant to an Award, in any form
whatsoever, (i) shall be deferred, or (ii) at the election of such Recipient,
may be deferred. Deferrals shall be for such periods and upon such terms as
the Committee, or in the case of Awards to Outside Directors, the Board of
Directors, may determine.

9.      Continuation of Employment.

        With respect to Awards granted to employees, the Committee shall
require that (a) Awards may only be granted to Recipients, and (b) a Recipient
must be an employee of the Company or a Subsidiary (or must have retired with
the approval of the Company or a Subsidiary) at the time an Award becomes
vested. Notwithstanding the foregoing, the Committee shall have the sole power
to determine the date of and the circumstances which shall constitute a
cessation of employment (including whether the spin-off of a Subsidiary
constitutes a cessation of employment of employees who continue in the employ
of Subsidiary subject to such spin-off) and to determine whether such
cessation is the result of retirement, death or any other reason. The
Committee may provide for the termination of any such outstanding Award if a
Recipient

                                      5
<PAGE>

ceases to be an employee of the Company or a Subsidiary or a Director and may
establish such other provisions with respect to the termination or disposition
of an Award on the death or retirement of a Recipient as it, in its sole and
absolute discretion, deems advisable.

10.     Employment Status.

        No Award shall be construed as imposing upon the Company or a
Subsidiary the obligation to continue the employment of a Recipient. No
employee or other person shall have any claim or right to be granted an Award
under the Plan.

11.     Director Stock Options.

        The Board of Directors may grant to each Outside Director serving on
the Company's Board of Directors a stock option to purchase up to 15,000
shares of Common Stock as an Outside Director (a "Director Stock Option").
Director Stock Options shall contain such terms as the Board of Directors
shall determine; provided, however, that such Stock Options shall vest on the
first anniversary of the date of grant, shall have a term of ten (10) years
and must be exercised prior to the first anniversary of the Outside Director's
termination of service as a Director.

12.     Stock Option Price.

        The purchase price per share of Common Stock under each Stock Option
shall not be less than the closing price for the Common Stock on the NASDAQ
Exchange (or on the principal securities exchange or other market on which the
Common Stock is then being traded) on the date the Stock Option or Incentive
Stock Option is granted or if such closing price is not reported on the date
of grant, the last reported closing price. Payment for exercise of any Stock
Option granted hereunder shall be made in cash.

13.     Registration of Stock.

        Each Award and each Director Stock Option shall be subject to the
requirement that if at any time the Committee (or, in the case of a Director
Stock Option, counsel for the Company) shall determine that qualification or
registration under any state or federal law of the shares of Common Stock,
Restricted Shares, Stock Options, Incentive Stock Options, or other securities
thereby covered or the consent or approval of any governmental regulatory body
is necessary or desirable as a condition of or in connection with the granting
of such Award or Stock Option or the purchase of shares thereunder, the Award
or Stock Option may not be paid or exercised in whole or in part unless and
until such qualification, registration, consent or approval shall have been
effected or obtained free of any conditions the Committee, in its sole
discretion, deems unacceptable.

14.     Assignability.

        No Award or Director Stock Option shall be transferable or assignable
by the Recipient other than by will or the laws of descent and distribution
and during the lifetime of the Recipient

                                      6
<PAGE>

shall be exercisable or payable only by him or her. Notwithstanding the
foregoing, the Committee may permit a Recipient of a Stock Option (other than
an Incentive Stock Option) or an Outside Director Recipient, to transfer such
Stock Option to any one or more of the following: such Recipient's or Outside
Director Recipient's family member, a trust established primarily for the
benefit of a family member, or to an entity which is a corporation,
partnership, or limited liability company (or any other similar entity) the
owners of which are primarily the aforementioned persons or trusts. Any such
Stock Option so transferred shall be subject to the provisions of Section 9 or
11 as the case may be, concerning the exercisability during such transferor's
employment or service as a Director.

15.     Dilution or Other Adjustments.

        In the event of any changes in the capital structure of the Company,
including but not limited to a change resulting from a stock dividend or
split-up, or combination or reclassification of shares, the Board of Directors
shall make such equitable adjustments with respect to Awards and Director
Stock Options or any other provisions of this Plan as it deems necessary and
appropriate, including, if necessary, any adjustment in the maximum number of
shares of Common Stock subject to the Plan or the number of shares of Common
Stock subject to an outstanding Award or Director Stock Option. In the absence
of any of the foregoing transactions, in no event shall Stock Options be
re-priced to a lower price without approval of the stockholders of the Company
and in no event shall Stock Options be cancelled and reissued at a lower price
if the reissuance occurs within six (6) months of cancellation.

16.     Change of Control.

        a.     Acceleration.  Except as otherwise provided in this Plan or in
               an agreement reflecting an Award, upon the occurrence of a
               Change of Control:

               i.    All outstanding Stock Options shall become fully
                     exercisable.

               ii.   All Stock Awards shall become fully vested.

               iii.  Performance Units may be paid out in such manner and
                     amounts as determined by the Committee.

        b.     Definition of Change in Control.  For purposes of this Plan,
               the term "Change in Control" means a change in the beneficial
               ownership of the Company's voting stock or a change in the
               composition of the Board of Directors which occurs as follows:

               i.     any "Person" (as such term is used in Section 13(d) and
                      14(d)(2) of the Securities Exchange Act of 1934), other
                      than the Company, any entity owned, directly or
                      indirectly, by the stockholders of the Company in
                      substantially the same proportions as their ownership of
                      stock of the Company, and any trustee or other fiduciary
                      holding securities under an employee benefit plan of the
                      Company or its subsidiaries or such

                                      7
<PAGE>
