                             POWELL INDUSTRIES, INC.
                  INCENTIVE COMPENSATION PLAN FOR 2000 ("PLAN")

1.     PLAN PURPOSE

       This Plan is one element of the executive compensation program at Powell
       Industries, Inc. ("Company") and its subsidiaries. The Plan provides key
       corporate and subsidiary employees the opportunity to earn annual cash
       incentive compensation amounts based on the performance of the Company or
       the subsidiary for which they have direct responsibility as well as on
       their individual contribution to the performance of those entities. Thus
       the Plan provides a variable annual incentive that links pay to
       performance.

2.     GENERAL DESCRIPTION

       Key corporate and subsidiary executives and managers will be designated
       annually to be Participants in the Plan. A maximum potential incentive
       compensation amount ("Maximum IC Amount") will be set annually for each
       such Participant based on that Participant's potential contribution to
       the performance of the Company or subsidiary. This Maximum IC Amount may
       range from ten per cent (10%) to one hundred per cent (100%) of a
       Participant's base salary on the first day of the Plan year. The Plan
       year is the fiscal year of the Company.

       Each Participant may earn between zero and one hundred percent of this
       Maximum IC Amount ("Earned IC Amount") depending on how the Company or
       subsidiary that employs the Participant performs during the Plan year
       against pre-established performance targets. Plan performance measures
       for 2000 are described in paragraph 4 below.

       Performance targets vary by subsidiary and will be established annually
       for the Company and each subsidiary based on that entity's historical
       performance, current mission and strategy, and projected profit and
       growth capability. Prevailing general business conditions will also be
       considered in establishing the performance targets.

       The Compensation Committee of the Company's Board of Directors in
       conjunction with the Company's Chief Executive Officer ("CEO") will
       administer the Plan.

3.     ELIGIBILITY

       Participants will be designated annually. Participation in one year does
       not guarantee participation in the following year.

       Subsidiary presidents will recommend Participants and a Maximum IC Amount
       for each Participant to the CEO for approval. Each subsidiary president
       may also recommend to the CEO an incentive "pool" for employees of the
       subsidiary who are not Plan Participants.

       The CEO will recommend corporate Participants and their Maximum IC Amount
       for approval by the Compensation Committee, and the CEO may authorize use
       of an incentive "pool" for employees of Powell Industries, Inc. who are
       not Plan Participants.

4.     PERFORMANCE MEASURES AND TARGETS

       The following measures will be used to measure the performance of each
       subsidiary and the Company overall. The weighting percentage reflects the
       relative weight given to each performance measure.

       PERFORMANCE MEASURES FOR SUBSIDIARY PARTICIPANTS

       o  40% Weighting: each subsidiaries' Return On Revenues (earnings before
          taxes divided by total revenues)
       o  20% Weighting: each subsidiaries' Growth in Total Revenues Over Prior
          Year
       o  40% Weighing: each subsidiaries' Return On Net Assets (earnings before
          interest and taxes divided by the average net of total assets less
          current liabilities)

       PERFORMANCE MEASURES FOR CORPORATE PARTICIPANTS

       o  40% Weighting: the Company's Growth in Earnings Per Share Over Prior
          Year
       o  20% Weighting: the Company's Growth in Total Revenues Over Prior Year
       o  40% Weighting: the Company's Return On Equity (earnings after interest
          and taxes divided by average shareholder equity)

                 INCENTIVE COMPENSATION PLAN FOR 2000 ("PLAN")

       The CEO will establish at the beginning of the Plan year for each
       subsidiary and the Company a minimum and maximum target range for each
       performance measure. Each subsidiary will have unique targets. The
       Compensation Committee will review performance measures and targets for
       subsidiaries and will review and approve performance measures and targets
       for the Company. The CEO will approve measures and targets for each
       subsidiary. Targets will be communicated to Plan Participants.

5.     COMPUTATION OF AWARDS

       An IC Plan Calculation Form will be prepared annually for each subsidiary
       and the Company listing Participants, their base salary, and their
       Maximum IC Amount. This form will include tables for use in calculating
       the Earned IC Amount of each Participant based on the level of attainment
       of each performance target by a subsidiary or the Company for the Plan
       Year.

       The minimum range of either the Return on Revenue or the Return on Net
       Assets target must be met or exceeded by a subsidiary before any portion
       of the Maximum IC Amount is earned by Participants employed by that
       subsidiary. If the minimum of at least one of these targets is not met or
       exceeded, the Earned IC Amount by all Participants employed by that
       subsidiary will be zero. Similarly the Company must met or exceed the
       minimum Growth in EPS or Return on Equity or the Earned IC Amount of all
       Corporate Participants will be zero.

       Computation of each entity's performance against the Return on Revenue,
       Return on Net Assets or Earnings Per Share targets will be net of (after)
       provision for the total of the Earned IC Amounts for that entity.

       The CEO may authorize the use by a subsidiary of separate performance
       measures and targets for that subsidiary or for certain of its
       Participants provided their use is, in the best business judgment of the
       CEO, compatible and consistent with the purpose and provisions of this
       Plan.

       In addition to the Earned IC Amount a Participant may earn under this
       Plan, the Compensation Committee may, in its sole discretion, make
       additional discretionary awards to a Participant to recognize significant
       individual contributions. This discretionary award may not be more than
       thirty percent of the Participant's Maximum IC Amount.

       The Compensation Committee, in conjunction with the CEO, may for the
       purposes of this Plan adjust the financial results of a subsidiary or the
       Company to eliminate extraordinary charges or credits to earnings
       provided such charges or credits are in the reasonable business judgment
       of the Compensation Committee caused by events materially beyond the
       control of the Participants employed by that entity.

       Individuals may be named by the CEO as a Participant in the Plan after
       the beginning of the Plan year. Their Maximum IC Amount will be a
       percentage of their base salary when they become Participants prorated to
       reflect that portion of the Plan year for which they were a Participant.

6.     PAYMENT OF AWARDS

       Earned IC Amounts will be determined after the audited financial
       statements of the Company for the Plan year are complete, and paid in
       cash as soon as practical thereafter. A Participant must be an employee
       in good standing on the last day of the Plan year in order to receive
       their Earned IC Amount, except that Participants who die, retire, or
       become disabled in the Plan year will receive a prorated amount based on
       the portion of the Plan year for which they were a Participant. Prior to
       payment of such amounts, the Compensation Committee will review and
       certify the Earned IC Amounts for all Participants. Amounts due
       Participants under the Plan are an unfunded, general obligation of the
       Company.

7.     ADMINISTRATION OF PLAN

       The Compensation Committee, in conjunction with the CEO, administers the
       Plan. The Committee reserves the right to amend or terminate the Plan at
       any time. If the Plan is amended or terminated and as a consequence the
       Earned IC Amount of any Participant which would have otherwise been
       earned is eliminated, a part year Earned IC Amount shall be determined
       for each so affected Participant and such amount should be paid in cash
       to such Participants within thirty (30) calendar days of amendment or
       termination. Such part year Earned IC Amount shall be determined by using
       the un-audited year to date financial statements of the Company to
       estimate (including making provision for annualizing part year results)
       what each such Participant's full year Earned IC Amount would have been
       absent the amendment or termination, and this full year amount shall be
       prorated to a part year Earned IC Amount based on the number of full
       elapsed months of the Plan year prior to amendment or termination divided
       by twelve.

                                       END

time to time, the original of such letter of credit is delivered to Lender and
the issuer thereof is notified of, and acknowledges, the pledge and assignment
thereof to Lender; (g) no more than thirty (30) days have elapsed since the
invoice date of such Account, in the case of any Account for which GM is the

or employee of the account debtor with respect to such Account is an officer,
employee, agent or other Affiliate of Borrower; and (i) the account debtor with
respect to such Account has not asserted a counterclaim, defense or dispute and
does not have, and does not engage in transactions which may give rise to any
right of setoff or recoupment against such Account, other than in the case of GM
Accounts in which case the amount of such GM Account shall be deemed to be the
net amount after giving effect to such setoff or recoupment taken by GM. In no
event shall Accounts representing indebtedness of any Governmental Agency only
for progress payments under a Government Contract be considered Eligible
Accounts, except to the extent such indebtedness with respect to progress
payments is included as part of an Eligible Account representing indebtedness

     (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

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.

     3.7  Conduct of Accounts; Cross-Collateralization.
          --------------------------------------------

     (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
Obligations of Borrower to Lender (including, but not limited to, the Loans and
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
and clear of, and without deduction or withholding for or on account of, any
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.

     (b) Borrower shall, and shall cause each Subsidiary to, take prompt and

discharges, noise emissions or any other environmental, health or safety matter
affecting Borrower from any Person, including, but not limited to, the United
States Environmental Protection Agency or any state or local environmental

thereto. Borrower shall be liable for any tax or penalty imposed upon any
transaction under this Agreement or any of the other Financing Agreements or
giving rise to the Accounts or any other Collateral or which Lender may be
required to withhold or pay for any reason and Borrower agrees to indemnify and
hold Lender harmless with respect thereto, and to repay to Lender on demand the

Subsidiaries to keep its properties, in good repair, working order and condition
(reasonable wear and tear excepted) and, from time to time, make and cause each

replacements, additions and improvements thereto, so that the  business carried
on may be properly and advantageously conducted at all times in accordance with
prudent business management.

conduct a physical count of the Inventory at least once per fiscal year, and at
such other times as Lender reasonably requests, and shall promptly supply Lender
with a copy of such count accompanied by a report of the Value of such
Inventory, provided, that, Borrower may obtain certain parts and supplies on

consignment from GM needed for use in the assembly of the H2 Vehicles so long as
such parts and supplies shall at all times be segregated and separately
identifiable as consigned goods and in any report with respect to the Inventory
delivered to Lender under Section 7.20(a) hereof, such parts and supplies shall
be separately and clearly identified. Borrower shall not, except after prior
written notice to Lender, sell any Inventory on a bill-and-hold, guaranteed
sale, sale and return, sale on approval, or other repurchase or return basis;
provided, that, Borrower shall promptly furnish to Lender such reports with

respect thereto from time to time and in such form and substance as Lender may
require.

                                       42

controlled by it and occurring in connection with the use (or otherwise) of any
products manufactured or sold by it, and workmen's compensation insurance. Said
policies of insurance shall be satisfactory to Lender as to form, amount and
insurer. Borrower shall furnish certificates, policies or endorsements to Lender
as proof of such insurance, and, if it fails to do so, Lender is authorized, but
not required, to obtain such insurance at the expense of Borrower. All policies
shall provide for at least thirty (30) days prior written notice to Lender of
any cancellation or reduction of coverage and that Lender may act as attorney
for Borrower in obtaining, and at any time on or after the occurrence of an
Event of Default, adjusting, settling, amending and cancelling such insurance.

property insurance policies in form and substance satisfactory to Lender
specifying that the proceeds of such insurance shall be payable to Lender as its
interests may appear and further specifying that Lender shall be paid regardless
of an act or omission by Borrower. At its option, at any time on or after the
occurrence of an Event of Default, Lender may apply any insurance proceeds
received by Lender at any time to the cost of repairs or replacement of
Collateral and/or to payment of the Obligations, whether or not then due, in any
order and in such manner as Lender, in its discretion, may determine.

Corporation or (vi) incur any withdrawal liability with respect to any
multiemployer pension plan which is not fully bonded; and

     (b) as used in this Section 7.18, the term "employee pension benefit

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
termination fee in an amount equal to:

          (i)  two (2%) percent of the Maximum Credit, if such termination is
               effective on or prior to October 30, 2003; and

          (ii) one (1%) percent of the Maximum Credit, if such termination is
               effective after October 30, 2003 but prior to October 30, 2004.

Such early termination fee shall be presumed to be the amount of damages
sustained by said early termination and Borrower agrees that it is reasonable
under the circumstances currently existing. The early termination fee provided
for in this Section 10.1 shall be deemed included in the Obligations.

     10.2 Expenses and Additional Fees.
          ----------------------------

     (a)  Borrower shall pay to Lender on demand all reasonable costs and
expenses that Lender pays or incurs in connection with the negotiation,
preparation, consummation, administration, enforcement and termination of this
Agreement and the other Financing Agreements, including, without limitation: (i)
reasonable attorneys' and paralegals' fees and disbursements of counsel to
Lender and any Participant; (ii) costs and expenses (including reasonable

Agreement and the other Financing Agreements and the transactions contemplated
hereby and thereby; (iii) costs and expenses of lien and title searches and
title insurance; (iv) taxes, fees and other charges for recording any agreements

pay any amount or take any action required of Borrower under the Financing
Agreements that Borrower fails to pay or take; (vi) costs of appraisals,
environmental audits, inspections and verifications of the Collateral,

Collateral and Borrower's operations by Lender or its agents, plus a charge of

of forwarding loan proceeds, collecting checks and other items of payment, and
establishing and maintaining payment accounts and lock boxes; (viii) costs and
expenses of preserving and protecting the Collateral; and (ix) costs and
expenses (including attorneys' and paralegals' fees and disbursements) paid or
incurred to obtain payment of the Obligations, enforce the security interests
and liens of Lender, sell or otherwise realize upon the Collateral, and
otherwise enforce the provisions of this Agreement and the other Financing
Agreements, or to defend any claims made or threatened against Lender arising
out of the transactions contemplated hereby and thereby (including, without
limitation, preparations for and consultations concerning any such matters). The
foregoing shall not be construed to limit any other provisions of the Financing
Agreements regarding costs and expenses to be paid by Borrower.

     (b)  Borrower shall pay to Lender all of its customary charges and fees in
connection with (i) any payment, claim or refund relating to the dishonor of any
checks or other items of any of Borrower or Account Debtors, and (ii) wire
transfers to Borrower.

     (c)  All sums provided for in this Section 10.2 shall be part of the
Obligations, shall be payable on demand, and shall accrue interest after demand
for payment thereof at the highest rate of interest then

                                       52
<PAGE>

payable hereunder. Lender is hereby irrevocably authorized to charge any amounts
payable hereunder directly to any of the account(s) maintained by Lender with
respect to Borrower.

     10.3 Waiver of Existing Defaults.
          ---------------------------

     (a)  Subject to the terms and conditions contained herein, Lender hereby
waives: (i) Borrower's compliance with the covenants contained in Sections 6.11
and 6.13 of the Existing Agreement for the period through and including the date
hereof, (ii) Borrower's compliance with the covenants contained in Section
6.6(f) of the Existing Agreement for the period through and including the date
hereof, and (ii) Borrower's compliance with the covenant contained in Section
2(c)(i) of the letter agreement providing for Lender's consent to the formation
of GEP, dated September 14, 1999, by and among, Borrower, GEP, AMGSC and Lender
(the "General Engine Consent") for the period through and including the date
hereof.

     (b)  The waivers contained in Section 10.3(a) should not be construed as a
bar to or an express or implied waiver of any other or further Event of Default
which may have occurred on or prior to the date hereof, whether or not
continuing on that date, or any other or further Event of Default which may
occur after that date, whether similar in kind or otherwise, and shall not
constitute a waiver, express or implied of any of the rights or remedies of
Lender arising under the terms of the Existing Agreement, the Loan Agreement,
the General Engine Consent or the other Financing Agreements on any future
occasion or otherwise.

     10.4 Survival of Agreement.  All agreements, representations and warranties
          ---------------------
contained herein or made in writing by the parties hereto in connection with the
transactions contemplated hereby shall survive the execution and delivery of
this Agreement, the other Financing Agreements and the consummation of the
transactions contemplated herein or therein regardless of any investigation made
by or on behalf of Lender.

     10.5 No Waiver; Cumulative Remedies.  No failure to exercise, and no delay
          ------------------------------
in exercising on the part of Lender, any right, power or privilege under this
Agreement or under any of the other Financing Agreements or other documents
referred to herein or therein shall operate as a waiver thereof; nor shall any
single or partial exercise of any right, power or privilege hereunder or
thereunder preclude any other or further exercise  thereof or the exercise of
any other right, power and privilege.  No notice to or demand on Borrower not
required hereunder or any of the other Financing Agreements shall entitle
Borrower to any other or further notice or demand in similar or other
circumstances or constitute a waiver of the rights of Lender to any other or
further action in any circumstances without notice or demand.  The rights and
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
Financing Agreements or such other agreements and all such rights and remedies
may be exercised successively or concurrently.
