         Until payment in full of all Loan Facility Obligations and termination
of the Loan Documents, Borrower agrees as follows:

2.01 Use of Credit Accommodations. (a) Borrower shall use Credit Accommodations
only for the purpose of enabling Borrower to finance the cost of manufacturing,
producing, purchasing or selling the Items. Borrower may not use any of the
Credit Accommodations for the purpose of: (i) servicing or repaying any of
Borrower's pre-existing or future indebtedness unrelated to the Loan Facility

capital goods for use in Borrower's business; (iii) acquiring, equipping or

outside of the United States; or (v) in connection with a Retainage or Warranty
(unless approved by Ex-Im Bank in writing).

         (b) In addition, no Credit Accommodation may be used to finance the
manufacture, purchase or sale of any of the following:

                  (i) Items to be sold or resold to a Buyer located in a country
as to which Ex-Im Bank is prohibited from doing business as designated in the
Country Limitation Schedule;


                                       11
<PAGE>


                  (ii) that part of the cost of the Items which is not U.S.
Content unless such part is not greater than fifty percent (50%) of the cost of
the Items and is incorporated into the Items in the United States;

                  (iii) defense articles or defense services; or

                  (iv) without Ex-Im Bank's prior written consent, any Items to
be used in the construction, alteration, operation or maintenance of nuclear
power, enrichment, reprocessing, research or heavy water production facilities.

2.02 Loan Documents and Loan Authorization Agreement. (a) Each Loan Document and
this Agreement have been duly executed and delivered on behalf of Borrower, and
each such Loan Document and this Agreement are and will continue to be a legal
and valid obligation of Borrower, enforceable against it in accordance with its
terms.

         (b) Borrower shall comply with all of the terms and conditions of the
Loan Documents, this Agreement and the Loan Authorization Agreement.

2.03 Export-Related Borrowing Base Certificates and Export Orders. In order to
receive Credit Accommodations under the Loan Facility, Borrower shall have
delivered to Lender an Export-Related Borrowing Base Certificate as frequently
as required by Lender but at least within the past thirty (30) calendar days and
a copy of the Export Order(s) (or, for Revolving Loan Facilities, if permitted
by Lender, a written summary of the Export Orders) against which Borrower is
requesting Credit Accommodations. If Lender permits summaries of Export Orders,
Borrower shall also deliver promptly to Lender copies of any Export Orders
requested by Lender. In addition, so long as there are any Credit Accommodations
outstanding under the Loan Facility, Borrower shall deliver to Lender at least
once each month no later than the twentieth (20th) day of such month or more
frequently as required by the Loan Documents, an Export-Related Borrowing Base
Certificate.

2.04 Exclusions from the Export-Related Borrowing Base. In determining the
Export-Related Borrowing Base, Borrower shall exclude therefrom Inventory which
is not Eligible Export-Related Inventory and Accounts Receivable which are not
Eligible Export-Related Accounts Receivable. Borrower shall promptly, but in any
event within five (5) Business Days, notify Lender (a) if any then existing
Export-Related Inventory no longer constitutes Eligible Export-Related Inventory
or (b) of any event or circumstance which to Borrower's knowledge would cause
Lender to consider any then existing Export-Related Accounts Receivable as no
longer constituting an Eligible Export-Related Accounts Receivable.

2.05 Financial Statements. Borrower shall deliver to Lender the financial
statements required to be delivered by Borrower in accordance with Section 11 of
the Loan Authorization Agreement.

2.06 Schedules, Reports and Other Statements. Borrower shall submit to Lender in
writing each month (a) an Inventory schedule for the preceding month and (b) an
Accounts Receivable aging report for the preceding month detailing the terms of
the amounts due from each Buyer. Borrower shall also furnish to Lender promptly
upon request such information, reports, contracts, invoices and other data
concerning the Collateral as Lender may from time to time specify.

2.07 Additional Security or Payment. (a) Borrower shall at all times ensure that
the Export-Related Borrowing Base equals or exceeds the Credit Accommodation
Amount. If informed by Lender or if Borrower otherwise has actual knowledge that
the Export-Related Borrowing Base is at any time less than the Credit
Accommodation Amount, Borrower shall, within five (5) Business Days, either (i)
furnish additional Collateral to Lender, in form and amount satisfactory to
Lender and Ex-Im Bank or (ii) pay to Lender an amount equal to the difference
between the Credit Accommodation Amount and the Export-Related Borrowing Base.

         (b) For purposes of this Agreement, in determining the Export-Related
Borrowing Base there shall be deducted from the Export-Related Borrowing Base
(i) an amount equal to twenty-five percent (25%) of the outstanding face amount
of Commercial Letters of Credit and Standby Letters of Credit and (ii) one
hundred percent (100%) of the face amount of Warranty Letters of Credit less the
amount of cash collateral held by Lender to secure Warranty Letters of Credit.

         (c) Unless otherwise approved in writing by Ex-Im Bank, for Revolving
Loan Facilities (other than Transaction Specific Revolving Loan Facilities),
Borrower shall at all times ensure that the outstanding principal balance of the
Credit Accommodations that is supported by Export-Related Inventory does not
exceed sixty percent (60%) of the sum of the total outstanding principal balance
of the Disbursements and the undrawn face amount of all outstanding Commercial
Letters of Credit. If informed by Lender or if Borrower otherwise has actual
knowledge that the outstanding principal balance of the Credit Accommodations
that is supported by Inventory exceeds sixty percent (60%) of the sum of the
total outstanding principal balance of the Disbursements and the undrawn face
amount of all outstanding Commercial Letters of Credit, Borrower shall, within
five (5) Business Days, either (i) furnish additional non-Inventory Collateral
to Lender, in form and amount satisfactory to Lender and Ex-Im Bank, or (ii) pay
down the applicable portion of the Credit Accommodations so that the above
described ratio is not exceeded.

2.08 Continued Security Interest. Borrower shall not change (a) its name or
identity in any manner, (b) the location of its principal place of business, (c)
the location of any of the Collateral or (d) the location of any of the books or
records related to the Collateral, in each instance without giving thirty (30)
days prior written notice thereof to Lender and taking all actions deemed
necessary or appropriate by Lender to continuously protect and perfect Lender's
Liens upon the Collateral.

2.09 Inspection of Collateral. Borrower shall permit the representatives of
Lender and Ex-Im Bank to make at any time during normal business hours
inspections of the Collateral and of Borrower's facilities, activities, and
books and records, and shall cause its officers and employees to give full
cooperation and assistance in connection therewith.

2.10 General Intangibles. Borrower represents and warrants that it owns, or is
licensed to use, all General Intangibles necessary to conduct its business as
currently conducted except where the failure of Borrower to own or license such
General Intangibles could not reasonably be expected to have a Material Adverse
Effect.

five (5) Business Days, notify Lender in writing of the occurrence of any of the
following:

         (a) Borrower or any Guarantor (i) applies for, consents to or suffers
the appointment of, or the taking of possession by, a receiver, custodian,

purpose of effecting any of the foregoing;

other than a Permitted Lien, against any of the Collateral which is not stayed

         (d) any proceeding is commenced by or against Borrower or any Guarantor
for the liquidation of its assets or dissolution;

         (e) any litigation is filed against Borrower or any Guarantor which has

insurance, with insurers acceptable to Lender, in such form and amounts, and
with such deductibles and other provisions, as Lender shall require, and
Borrower will provide evidence of such insurance to Lender, so that Lender is
satisfied that such insurance is, at all times, in full force and effect. Each
property insurance policy shall name Lender as loss payee and shall contain a
lender's loss payable endorsement in form acceptable to Lender and each
liability insurance policy shall name Lender as an additional insured. All
policies of insurance shall provide that they may not be cancelled or changed
without at least ten (10) days' prior written notice to Lender and shall
otherwise be in form and substance satisfactory to Lender. Borrower will
promptly deliver to Lender copies of all reports made to insurance companies.

2.13 Taxes. Borrower has timely filed all tax returns and reports required by
applicable law, has timely paid all applicable taxes, assessments, deposits and
contributions owing by Borrower and will timely pay all such items in the future

contested taxes; provided, that Borrower (a) in good faith contests Borrower's
obligation to pay such taxes by appropriate proceedings promptly and diligently
instituted and conducted; (b) notifies Lender in writing of the commencement of,

in all material respects with all provisions of all applicable laws and
regulations, including those relating to Borrower's ownership of real or

Documents, Borrower may borrow, repay and reborrow amounts under the Loan

and all accrued and unpaid interest thereon no later than the first Business Day
after the Final Disbursement Date.

         (b) If the Loan Facility is a Transaction Specific Loan Facility,
Borrower shall, within two (2) Business Days of the receipt thereof, pay to
Lender (for application against the outstanding Loan Facility Obligations and
accrued and unpaid interest thereon) all checks, drafts, cash and other

shall not commingle any such items of payment with any of its other funds or
property.
