Accommodations outstanding under the Loan Facility, Borrower shall deliver to
Lender an Export-Related Borrowing Base Certificate at least once each month.
Lender shall determine if daily electronic reporting reconciled monthly may
substitute for monthly Export-Related Borrowing Base Certificates. If the Lender

drafts, cash and other remittances it may receive in payment or on account of
the Export-Related Accounts Receivable, Export-Related Overseas Accounts
Receivable or any other Collateral, in precisely the form received (except for

shall hold such amounts in trust for Lender separate and apart and shall not
commingle any such items of payment with any of its other funds or property.

Obligations no later than the first Business Day after the Final Disbursement
Date, except for Eligible Export-Related Accounts Receivables and Eligible

amount equal to (i) twenty-five percent (25%) of the undrawn amount of

one hundred percent (100%) of the undrawn amount of outstanding 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 sum of the outstanding amount of

Export-Related Overseas Inventory (discounted by the relevant Advance Rate
percentages) in the Export-Related Borrowing Base does not exceed sixty percent
(60%) of the sum of the total outstanding amount of Disbursements and the

that the conditions of Section 2.16(g) are at any time not being met, Borrower
shall, within five (5) Business Days, either (i) furnish additional Collateral

Eligible Export-Related Overseas Inventory, in form and amount satisfactory to
Lender and Ex-Im Bank, or (ii) remove from the Export-Related Borrowing Base the
portion of Eligible Export-Related Overseas Accounts Receivable or Eligible

at Borrower's facilities in accordance with the time schedule and content for
such examinations that Lender requests. Such field examinations shall address at

Export-Related Historical Inventory Value in the Export-Related Borrowing Base
calculation shall reconcile those numbers against the calculation for the
relevant time periods using the Export-Related Inventory Value. Whenever
Export-Related Accounts Receivable or Export-Related Inventory derived from
Indirect Exports are in the Export-Related Borrowing Base, Lender shall verify
compliance with Section 2.15 herein, including taking a random sampling of
ultimate foreign purchasers.

      2.14  Economic Impact Approval. (a) For Loan Facilities up to and
including $10 million, Borrower acknowledges that Capital Goods may not be
included as Items, and Export-Related Inventory, Export-Related Overseas
Inventory, Export-Related Accounts Receivable and Export-Related Overseas
Accounts Receivable in connection with the sale of such Capital Goods may not be
included in the Export-Related Borrowing Base, if such Capital Goods would
enable a foreign buyer to establish or expand production of a product where, as
of the date of the Economic Impact Certification covering such Item: (i) the
Buyer is subject to a Final Anti-Dumping (AD) or Countervailing Duty (CVD)
order, or a Suspension Agreement arising from a AD or CVD investigation, and
such product is substantially the same as the product that is the subject of the
AD/CVD order or suspension agreement; or (ii) the Buyer is the subject of a
Section 201 injury determination by the International Trade Commission ("ITC")
and such product is substantially the same as a product that is the subject of
the ITC injury determination. Borrower may consult with Ex-Im Bank regarding the
appropriate application of this Section 2.14(a) and may, at its option, request
that Ex-Im Bank issue an Economic Impact Approval covering any Items listed in
Section 4.A. of the Loan Authorization Agreement. For Loan Facilities over $10
million involving Items that are Capital Goods, Borrower shall obtain from Ex-Im
Bank, and abide by, an Economic Impact Approval covering all Items listed in
Section 4(A) of the Loan Authorization Agreement.

      (b)   Borrower shall provide Lender with a certification in the form of
Annex B (an "Economic Impact Certification") covering the Items stated in
Section 4(A) of the Loan Authorization Agreement prior to Lender including such
Items in the Loan Authorization Agreement. Prior to Lender amending the Loan
Authorization Agreement to include additional Items, Borrower shall provide
Lender with an additional Economic Impact Certification covering such additional
Items.

      2.15  Indirect Exports. Indirect Exports may be included as Items in a
Loan Facility provided that funds available under such Loan Facility's
Export-Related Borrowing Base supported by Accounts Receivable and Inventory
derived from Indirect Exports at no time exceed ten percent (10%) of the Maximum
Amount of such Loan Facility, and provided, further that (a) the ultimate
foreign buyer for the Items must be located in a country in which Ex-Im Bank is
not legally prohibited from doing business in accordance with the Country
Limitation Schedule, and (b) the Borrower must make available to Lender
verifiable evidence of intent to export the Indirect Exports from the United
States, which evidence may be contained in the Export Orders and Accounts
Receivable Aging Reports and supporting documents. Lender must obtain written
consent from Ex-Im Bank prior to including funds derived from Indirect Exports
in an Export-Related Borrowing Base above the ten percent (10%) threshold.

      2.16  Overseas Inventory and Accounts Receivable. Upon the prior written
consent of Ex-Im Bank, Export-Related Overseas Accounts Receivable and
Export-Related Overseas Inventory of a Borrower or of an Affiliated Foreign
Person (as defined below) may be included in the Export-Related Borrowing Base
provided that conditions required by Ex-Im Bank, including the following, are
met:

      (d)   as of the Effective Date, or such later date when the Export-Related
Overseas Accounts Receivable and/or Export-Related Overseas Inventory are added
to the Loan Facility, Lender has obtained a valid and enforceable first priority
Lien in the Export-Related Overseas Accounts Receivable and Export-Related
Overseas Inventory, as applicable;

      (e)   as of the Effective Date, or such later date when the Export-Related

Export-Related Overseas Inventory;

      (f)   the Export-Related Overseas Accounts Receivable are due and payable
in United States Dollars or other currency acceptable to Ex-Im Bank; and

      (g)   at no time may the portion of the Export-Related Borrowing Base
derived from Eligible Export-Related Overseas Accounts Receivable and Eligible
Export-Related Overseas Inventory exceed fifty percent (50%) of the
Export-Related Borrowing Base.

            For purposes hereof, an "Affiliated Foreign Person" shall mean a
