     (b)  Notwithstanding anything to the contrary contained herein or in any of

or the Maximum Credit, provided, that, should Lender so permit in any one
                       --------  ----
instance it shall not operate to limit, waive or otherwise affect any rights of
Lender on any future occasions.  In such event, and without limiting the right
of Lender to demand payment of the Obligations, or any portion thereof, in
accordance with any other terms of this Agreement or the other Financing
Agreements, Borrower shall remain liable therefor and Borrower shall, upon
demand by Lender, which may be made at any time and from time to time,
immediately repay to Lender the entire amount of such excess(es).

Agreements. Any such payments made or obligations incurred by Lender, including
without limitation, any of the same made after termination or non-renewal of
this Agreement or the other Financing Agreements with respect to Letter of
Credit Accommodations extended prior to such termination or non-renewal, shall
automatically be treated for purposes hereof as Loans and shall accrue interest

purchased with such Letter of Credit Accommodation, plus (B) the freight, duty
                                                    ----

time outstanding shall not exceed the Maximum Credit.

     3.4  Reserves.
          --------

     (a)  Without limiting any other rights and remedies of Lender hereunder or
under the other Financing Agreements, all Loans made or otherwise available to
Borrower pursuant to the Lending Formulas, the lending sublimits set forth in
Sections 3.1(b) and 3.2(f) and the Maximum Credit shall be subject to Lender's
continuing right, in its discretion, to establish a reserve against the
availability of such Loans, and to increase and decrease such reserve from time
to time, if and to the extent that, in Lender's sole judgment, such reserve is
necessary for any reason including, (i) to protect Lender against possible non-
payment for any reason by Account Debtors or possible non-payment of any of the
Obligations, or in respect of any state of facts which does or would, with
notice or passage of time or both, constitute an Event of Default hereunder,
(ii) to reflect intercompany profit between Borrower and GEP, (iii) to reflect
the costs of completion (including, any and all parts, labor and overhead) with
respect to Eligible Humvee Finished Goods Inventory consisting of fully operable
Humvee vehicles awaiting minor parts or details, as determined by Lender, (iv)
to reflect the costs of completion (including, any and all parts, labor and
overhead) with respect to Eligible H1 Vehicle Finished Goods Inventory
consisting of fully operable H1 Vehicles awaiting minor parts or details, as
determined by Lender, (v) to reflect the value of any H1 Vehicles or Humvees
which are used for demonstration or test drives, and  (vi) to reflect, in
Lender's discretion, a reserve in the amount of $1,500,000 in the event that
Borrower fails to refinance the obligations of Borrower under the Senior Note
Indenture on terms and subject to conditions satisfactory in all respects to
Lender by no later than March 1, 2002.

     (b)  Without limiting the generality of the foregoing, except as Lender may
otherwise determine, in its discretion, from time to time, Lender shall
establish a special reserve against the amount of the Loans otherwise available
to Borrower pursuant to the Lending Formulas (without regard to the lending
sublimits set forth in Sections 3.1(b) and 3.2(f) and the Maximum Credit), in an
amount equal to the unliquidated progress payments received by Borrower from any
Governmental Agency or prime contractor under any Government Contract at any
time outstanding.

     3.5  Fees.
          ----

     (a)  As a closing fee, Borrower shall pay to Lender the aggregate amount of

     (b)  As a servicing fee, Borrower shall pay to Lender the aggregate amount
of $20,000 for each month (or part thereof) that this Agreement is in effect or
so long as any of the Obligations are outstanding, which fee shall be fully
earned as of the first day of each month, but shall be payable in arrears on the
first day of the next month.  The first payment of such fee shall be on the
first day of the month after the date hereof.

     (c)  With respect to each month (or part thereof) that this Agreement is in
effect or so long as any of the Obligations are outstanding, Borrower shall pay
to Lender an aggregate  fee at a rate equal to one-half of one ( 1/2 of 1%)
percent per annum calculated for such month and payable monthly in arrears on
the first day of the next  month, upon the excess, if any, of: (i) the Maximum
Credit over (ii) the average of the daily principal balances of the outstanding
Loans and the Letter of Credit Accommodations for such month (or part thereof).

                                       18
<PAGE>

     (d)  The fees provided for in this Section 3.5 shall be in addition to all
other amounts payable by Borrower under this Agreement and the other Financing
Agreements and represent compensation for services rendered and to be rendered
separate and apart from the lending of money or the use, detention or
forbearance of money.  Such fees may, at Lender's option, be charged directly to
any account(s) of Borrower maintained with Lender.  All fees and expenses shall
be nonrefundable when paid.  All fees and expenses specified or referred to in
this Agreement due to Lender shall constitute part of the Obligations and shall
be secured by all of the Collateral.  All fees provided for in this Section 3.5
which are expressed as a per annum charge shall be calculated on the basis of
the actual number of days elapsed in a three hundred sixty (360) day year.

     3.6  Interest.
          --------

     (a)  Interest on all of the Loans and other non-contingent Obligations
shall be payable by Borrower to Lender at the Interest Rate.

     (b)  In no event shall the Interest Rate and other charges under this
Agreement or the other Financing Agreements exceed the highest rate permitted
under any applicable law or regulation, which a court of competent jurisdiction
shall, in the final determination, deem applicable hereto.  In the event that a
court determines that Lender has received interest and other charges hereunder
in excess of the highest rate applicable hereto, 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 the
provisions  hereof shall be deemed amended to provide for the highest
permissible rate.

     (c)  Subject to the foregoing, all interest charges hereunder or in
connection herewith shall be (i) computed as provided herein and in the other
Financing Agreements and (ii) paid monthly on the first day of each calendar
month, or, at Lender's option, charged to Borrower's account(s) maintained by
Lender as of the first day of each calendar month and deemed paid by the first
amounts subsequently credited thereto.

     (d)  Without limiting Lender's continuing right to demand payment of the
Loans and other Obligations, or any portion thereof, in accordance with the
terms of this Agreement, or any of the other Financing Agreements, all interest
accruing hereunder on and after the date of any Event of Default or termination
or non-renewal hereof, shall be payable on demand.

     (a)  Lender may maintain one or more accounts reflecting the Loans,
repayments of the Loans and payments of the other Obligations and any of the
Collateral contemplated under this Agreement or the other Financing Agreements
with respect to Borrower, as Lender shall, in its discretion, determine.  All
Loans shall be charged to a loan account in the name of Borrower on Lender's
books.  All Collateral held by or granted to Lender by Borrower or any third
person shall be security for the payment and performance of any and all

the Letter of Credit Accommodations), notwithstanding the maintenance of
separate accounts for Borrower, and type of Collateral or the existence of any
notes.

     (b)  Borrower shall make all payments in respect of the Obligations free

setoff, counterclaim, defense, duties, taxes, levies, imposts, fees, deductions,
withholdings, restrictions or conditions of any kind or nature whatsoever.

     (c)  All Loans and other Obligations shall be payable to Lender at its
address specified herein or at such other place as Lender may hereafter
designate in writing from time to time.  Lender may apply

                                       19
<PAGE>

payments received or collected from Borrower or for the account of Borrower
(including, without limitation, the monetary proceeds of collections or of
realization upon any Collateral) to such of the Obligations arising whether or
not then due in whatever order and manner as Lender, in its discretion,
determines. Upon the request of Lender, Borrower shall execute and deliver to
Lender one or more promissory notes, in form and substance satisfactory to
Lender, to further evidence the Loans, or any portion thereof.

     (d)  If after receipt of any payment of, or proceeds applied to the payment
of, all or any part of the Obligations, Lender is for any reason required to
surrender such payment or proceeds to any Person, because such payment or
proceeds is invalidated, declared fraudulent, set aside, determined to be void
or voidable as a preference, or a diversion of trust funds, or for any other
reason, then the Obligations or any part thereof intended to be satisfied shall
be revived and continue and this Agreement shall continue in full force as if
such payment or proceeds had not been received by Lender and Borrower shall be
liable to pay to Lender, and hereby indemnify Lender and hold it harmless for
the amount of such payment or proceeds surrendered.  The provisions of this
Section 3.7(d) shall be and remain effective notwithstanding any contrary action
which may have been taken by Lender in reliance upon such payment or proceeds,
and any such contrary action so taken shall be without prejudice to Lender's
rights under this Agreement and shall be deemed to have been conditioned upon
such payment or proceedings having become final and irrevocable.  The provisions
of this Section 3.7(d) shall survive the termination of this Agreement and the
other Financing Agreements.

     (e)  At Lender's option, all principal, interest, fees, commissions, costs,
expenses, or other charges hereunder, under the other Financing Agreements or in
connection herewith or therewith, and any and all Loans, may be charged directly
to any account(s) of Borrower maintained by Lender.

     (f)  Lender shall render to Borrower at the address of Borrower set forth
in Section 10.6 hereof, each month, one or more statements with respect to the
loan account(s) maintained by Lender with respect to Borrower pursuant to the
provisions hereof, as of the end of each month while this Agreement is in
effect.  Such statements of account shall be considered correct, and deemed
accepted by and conclusively binding upon Borrower, except to the extent Lender
shall receive from Borrower written notice of all exceptions to such statement
of account with specificity, within forty-five (45) days from the date of
sending.

     3.8  Use of Proceeds.  All Loans to Borrower pursuant to the provisions

received by it, to the extent that such taxes have become due and payable,
except taxes the validity of which are being contested in good faith by
appropriate proceedings and with respect to which adequate reserves have been

accrued and unpaid Federal, State, county, local, foreign and other taxes
whether or not yet due and payable and whether or not disputed.

license or other right owned by any other Person and no claim or litigation is
pending or threatened against or affecting Borrower contesting its right to sell
or use any such product, process, method, substance, part or other material.  No

     8.2  Remedies.
          --------

     (a)  Without limiting Lender's rights to demand payment sooner as provided
in this Agreement, upon or at any time after the occurrence of any one or more
of such Events of Default, upon termination of this Agreement or the other
Financing Agreements, or if this Agreement and the other Financing Agreements
are not renewed, in addition to any other rights Lender may have under the
Financing Agreements or otherwise:

          (i)   Lender may, at any time thereafter, at its option, without
presentment for payment, demand, notice of dishonor or notice of protest or any
other or further notice, all of which are hereby expressly waived by Borrower,
declare any or all of the Obligations to be immediately due and payable,
together with interest at the highest rate of interest hereunder until fully and
indefeasibly paid, and

          (ii)  each Participant, to the fullest extent permitted by applicable
law, shall have the right to (A) set off against the Obligations any and all
deposits (whether general or special, time or demand, provisional or final),
credits, balances, accounts, monies or other assets which are the property of
Borrower and held by such Participant or owed by such Participant to Borrower
and (B) remit the same to Lender for application to the Obligations, and

          (iii) without further notice to Borrower, Lender may appropriate, set
off and apply to the payment of any or all of the Obligations, any or all
Collateral, in such manner as Lender shall determine, enforce payment of any
Collateral, settle, compromise or release in whole or in part, any amounts owing
on the Collateral, make allowances and adjustments with respect thereto, issue
credits in Lender's or Borrower's name, sell, assign and deliver the Collateral
(or any part thereof), at public or private sale, at broker's board, for cash,
upon credit or otherwise, at Lender's option and discretion, and Lender may bid
or become purchaser at any such sale, if public, free from any right of
redemption which is hereby expressly waived; and

                                       47
<PAGE>

          (iv)  without limiting the generality of the foregoing, Lender is
hereby authorized at any time and from time to time, to set off and apply any
and all deposits (general or special, time or demand, provisional or final) at
any time held and other Indebtedness at any time owing by Lender to or for the
credit or the account of Borrower against any and all of the Obligations,
whether or not then due and payable, and

          (v)   Lender shall have the right, without notice to Borrower (except
as otherwise expressly provided herein), at any time and from time to time in
its discretion, with or without judicial process or the aid or assistance of
others and without cost to Lender (A) to enter upon any premises other than the
H2 Facility (except that if any Collateral is located in H2 Facility Borrower
shall cooperate in all respects with Lender and assist Lender in obtaining
access to the H2 Facility) on or in which any of the Inventory or Equipment may
be located and, without resistance or interference by Borrower, take possession
of the Inventory; (B) to complete processing, manufacturing and repair of all or
any portion of the Inventory using the Equipment; (C) to sell, foreclose or
otherwise dispose of any part or all of the Inventory on or in any premises of

and (E) to remove any or all of the Inventory from any premises on or in which
the same may be located, for the purpose of effecting the sale,  foreclosure or
other disposition thereof or for any other purpose.

     (b)  Lender shall have all of the rights and remedies of a secured party
under the UCC or applicable law of any other State in which any Collateral may
be situated, in addition to all of the rights and remedies set forth in this
Agreement and the other Financing Agreements, and in any instrument or document
referred to herein or therein, and/or under any other applicable law relating to
this Agreement, the other Financing Agreements, the Obligations or the
Collateral.

     (c)  Borrower agrees that the giving of five (5) days notice by Lender to
its address set forth below, designating the place and time of any public sale
or of the time after which any private sale or other intended disposition of the
Collateral is to be made, shall be deemed to be reasonable notice thereof and
Borrower waives any other notice with respect thereto.

     (d)  The net cash proceeds resulting from the exercise of any of the
foregoing rights or remedies shall be applied by Lender to the payment of the
Obligations in such order as Lender may elect, and Borrower shall remain liable
to Lender for any deficiency.

     (e)  In the event Lender institutes an action to recover any Collateral or
seeks recovery of any Collateral by way of prejudgment remedy or otherwise,
Borrower hereby irrevocably waives (i) the posting of any bond, surety or
security with respect thereto which might otherwise be required, (ii) any demand
for possession prior to the commencement of any suit or action to recover the
Collateral, and (iii) any requirement that Lender retain possession and not
dispose of any Collateral until after trial or final judgment.

agreement with any Person, which constitutes, or with notice or passage of time
or both would constitute, an Event of Default hereunder or under any of the
other Financing Agreements, or pay or bond on appeal any judgment entered
against Borrower (irrespective of the amount of said judgment or the time
elapsed since entry thereof), and charge Borrower's account therefor, such
amounts to be repayable by Borrower on demand, together with interest thereon at
the highest rate of interest hereunder; provided, however, Lender shall be under
                                        --------  -------
no obligation to effect such cure, payment or bonding and shall not, by making
any payment for Borrower's account, be deemed to have assumed any obligation or
liability of Borrower.

                                       48
<PAGE>

     (g)  The enumeration of the foregoing rights and remedies is not intended
to be exclusive, and such rights and remedies are in addition to and not by way
of limitation of any other rights or  remedies Lender may have under the UCC or
other applicable law.  Lender shall have the right to determine which rights and
remedies, and in which order any of the same, are to be exercised, and to
determine which Collateral is to be proceeded against and in which order, and
the exercise of any right or remedy shall not preclude the exercise of any
others, all of which shall be cumulative.

     (h)  No act, failure or delay by Lender shall constitute a waiver of any of
the rights and remedies of Lender.  No single or partial waiver by Lender of any
provision of this Agreement or any of the other Financing Agreements, or breach
or default thereunder, or of any right or remedy which Lender may have shall
operate as a waiver of any other provision, breach, default, right or remedy or
of the same provision, breach, default, right or remedy on a future occasion.

     (i)  Borrower waives presentment, notice of dishonor, protest and notice of
protest of all instruments included in or evidencing any of the Obligations or
the Collateral and any and all notices or demands whatsoever (except as
expressly provided herein).  Lender may, at all times, proceed directly against
Borrower to enforce payment of the Obligations and shall not be required to take
any action of any kind to preserve, collect or protect any rights in the
Collateral.


SECTION 9.     COLLECTION AND ADMINISTRATION
----------     -----------------------------

     9.1  Collections; Management of Collateral.
          -------------------------------------

     (a)  Until the authority of Borrower to do so is curtailed or terminated at
any time by Lender, Borrower shall, at its expense and on behalf of Lender,
collect, as the property of Lender and in trust for Lender, all remittances and
all amounts unpaid on Accounts or other Collateral, and Borrower shall not
commingle such collections with Borrower's own funds.  Borrower shall on the day
received remit all such collections to Lender in the form received duly endorsed
by Borrower for deposit with Lender, unless Lender shall direct Borrower
otherwise.  All amounts collected on Accounts or other Collateral when received
by Lender at such place as Lender may designate from time to time shall be
credited to the loan account of Borrower, after adding one (1) business day for
federal funds wire transfers and two (2) business days for checks and other
remittances, including, without limitation, checks issued by a Governmental
Agency, in each case as to any form of remittance, conditional upon final
payment to Lender.

     (b)  Notwithstanding anything to the contrary contained in Section 9.1(a)
above, if at any time there are no Loans outstanding on each such day that there
are no Loans outstanding, for purposes of calculating interest on the
Obligations for such day, all amounts collected on Accounts or other Collateral
received by Lender in its account designated for such purpose will be applied
(conditional upon final collection) to the Obligations on the business day of
receipt by Lender provided such payments and notice thereof are received in
accordance with Lender's usual and customary practices as in effect from time to
time and within sufficient time to credit Borrower's loan account on such day,
and if not, then on the next business day. To the extent Lender may hold cash
collateral to secure all of the Obligations on terms and conditions determined
by Lender, so long as no Event of Default shall exist or have occurred and be
continuing, Borrower shall receive a credit to its loan account maintained by
Lender on the funds held by Lender at a rate equal to three (3%) percent per
annum less than the Prime Rate. Such credit shall be applied to the loan account
of Borrower as of the first day of each month.

     (c)  Borrower shall immediately upon obtaining knowledge thereof report to
Lender all reclaimed, repossessed or returned goods, material claims of Account
Debtors and any other matter affecting the

                                       49
<PAGE>

value, enforceability or collectibility of Accounts. At Lender's request, any
goods reclaimed or repossessed by or returned to Borrower will be set aside,
marked with Lender's name and held by Borrower for the account of Lender and
subject to the security interests of Lender. All claims and disputes relating to
Accounts are to be promptly adjusted within a reasonable time, at Borrower's own
cost and expense. Lender may, at its option, settle, adjust or compromise claims
and disputes relating to Accounts which are not adjusted by Borrower within a
reasonable time.

     9.2 Right of Inspection; Access.  Lender and its representatives shall at
         ---------------------------
all times have free access to and right of inspection of the Collateral and have
full access to and the right to examine and make copies each of Borrower's books
and records, to confirm and verify all Accounts, to perform general audits and
to do whatever else Lender deems necessary to protect the interests of Lender.
Lender may at any time remove from the premises of Borrower or require Borrower
or any accountants and auditors employed by Borrower to deliver any books and
records and Lender may, without cost or expense to them, use such of Borrower's
personnel, supplies, computer equipment and space at its places of business as
may be reasonably necessary for the handling of collections.

     9.3 Lock Box or Blocked Account.  Borrower shall, in the manner requested
         ---------------------------
by Lender from time to time, direct that all proceeds of Accounts, letters of
credit, banker's acceptances and other proceeds of Collateral shall be payable
to a lock box or post office box designated by Lender and under its control
and/or deposited into a blocked account under its control and/or deposited into
an account maintained in Lender's name and under its control and in connection
therewith shall execute such lock box, blocked account and other agreement as
Lender in its discretion shall specify.

     9.4 Accounts Documentation.  Borrower shall maintain its shipping forms,
         ----------------------
invoices and other related documents in a form satisfactory to Lender and shall
maintain its books, records and accounts in accordance with GAAP consistently
applied. Borrower shall keep and maintain, at its cost and expense, satisfactory
and complete books and records of all Accounts, all payments received or credits
granted thereon, and all other dealings therewith. At such times as Lender may
reasonably request, Borrower shall deliver to Lender all original documents
evidencing the sale and delivery of goods or the performance of services which
created any Accounts, including, but not limited to, all original contracts,
orders, invoices, bills of lading, warehouse receipts, delivery tickets and
shipping receipts, together with schedules describing the Accounts and/or
written confirmatory assignments to Lender of each Account, in form and
substance satisfactory to Lender and duly executed by Borrower, together with
such other information as Lender may request. In no event shall the making or
the failure to make or the content of any schedule or assignment or Borrower's
failure to comply with the provisions hereof be deemed or construed as a waiver,
limitation or modification of the security interest in, lien upon and assignment
of the Collateral or the representations, warranties or covenants under this
Agreement or the other Financing Agreements. Any documents, schedules, invoices
or other papers delivered to Lender, pursuant to this Section or otherwise, may
be destroyed or otherwise disposed of by them one (1) year after the same are
delivered, unless Borrower makes written request therefor and pays all expenses
attendant to their return, in which event Lender or such Lender shall return
same when their actual or anticipated need therefor has ceased.

     9.5 Specific Powers.  Borrower hereby constitutes Lender and its designee,
         ---------------
as its attorney-in-fact, at its own cost and expense, to exercise at any time
all or any of the following powers which, being coupled with an interest, shall
be irrevocable until all Obligations have been paid in full: (a) to receive,
take, endorse, assign, deliver, accept and deposit, in the name of Lender or
Borrower, any and all checks, notes, drafts, remittances and other instruments
and documents relating to the Collateral; (b) on or after the occurrence of an
Event of Default, or an event which with notice, passage of time or both would
constitute an Event of Default, to receive, open and dispose of all mail
addressed to Borrower and to notify postal authorities to change the address for
delivery thereof to such address as Lender may designate; (c) to transmit to
Account Debtors notice of Lender's interest therein and to request from such
Account

                                       50
<PAGE>

Debtors at any time, in the name of Lender or Borrower or that of Lender's
designee, information concerning the Accounts and the amounts owing thereon; (d)
on or after the occurrence of an Event of Default, or an event which with
notice, passage of time or both would constitute an Event of Default, to notify
Account Debtors to make payment directly to Lender; (e) on or after the
occurrence of an Event of Default, or an event which with notice, passage of
time or both would constitute an Event of Default, to take or bring, in the name
of Lender or Borrower, all steps, actions, suits or proceedings deemed by Lender
necessary or desirable to effect collection of the Collateral; and (f) to
execute in Borrower's name and on its behalf any UCC financing statements or
amendments thereto. Borrower hereby releases Lender and its officers, employees
and designees, from any liability arising from any act or acts under this
Agreement or in furtherance thereof, whether of omission or commission, and
whether based upon any error of judgment or mistake of law or fact, except as a
result of Lender's gross negligence or wilful misconduct as determined pursuant
to a final non-appealable order of a court of competent jurisdiction.

SECTION 10.  EFFECTIVE DATE; TERMINATION;
               COSTS; MISCELLANEOUS
               --------------------

     10.1 Term.
          ----

     (a)  This Agreement and the other Financing Agreements shall become
effective as of the date set forth on the first page hereof and shall continue
in full force and effect for a term ending October 30, 2004 (the "Renewal
Date"), and from year to year thereafter, unless sooner terminated pursuant to
the terms hereof.

     (b)  Lender or Borrower may terminate this Agreement and the other
Financing Agreements effective on the Renewal Date or on the anniversary of the
Renewal Date in any year by giving to the other party at least sixty (60) days
prior written notice; provided, that, this Agreement and all other Financing
                      -------- -----
Agreements must be terminated simultaneously.

     (c)  In addition, Lender shall have the right to terminate this Agreement
and the other Financing Agreements as to future Loans and Letter of Credit
Accommodations and other liabilities of Lender immediately at any time upon the
occurrence of an Event of Default or an act, condition or event which with
notice or passage of time or both would constitute an Event of Default.

     (d)  Upon the effective date of termination or non-renewal of the Financing
Agreements, Borrower shall pay to Lender, in full, all outstanding and unpaid
Obligations (including but not limited to the Loans and all interest, fees
(including the early termination fees provided herein, if applicable), charges,
expenses and other amounts provided for hereunder, under the other Financing
Agreements or otherwise) and shall furnish cash collateral to Lender for all
undrawn amounts available pursuant to previously issued and outstanding Letter
of Credit Accommodations, by wire transfer in federal funds to such bank account
of Lender, as Lender may, in its discretion, designate in writing to Borrower
for such purpose.  Interest at the Interest Rate shall be due until and
including the next business day, if the amounts so paid by Borrower to the bank
account designated by Lender are received in such bank account later than 12:00
noon, New York, New York time.

     (e)  No termination of the Financing Agreements shall relieve or discharge
Borrower of its duties, obligations and covenants under the Financing Agreements
until all Obligations have been fully discharged and paid, and Lender's
continuing security interest in the Collateral shall remain in effect until all
such Obligations have been fully discharged and paid.

                                       51
<PAGE>

     (f)  If Lender terminates this Agreement or the other Financing Agreements
upon the occurrence of an Event of Default or at the request of Borrower prior
to the end of the then current term of this Agreement and the other Financing
Agreements, in view of the impracticality and extreme difficulty of ascertaining
actual damages and by mutual agreement of the parties as to a reasonable
calculation of Lender's lost profits as a result thereof, Borrower hereby agrees
to pay to Lender, upon the effective date of such termination, an early

               effective after October 30, 2003 but prior to October 30, 2004.

any other right, power and privilege.  No notice to or demand on Borrower not

remedies of Lender under this Agreement, the other Financing Agreements and any
other present and future agreements between Lender and Borrower are cumulative
and not exclusive of any rights or remedies provided by law or under any of the
