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.

2.11  Notice of Certain Events.  Borrower shall promptly, but in
any event within 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, trustee, liquidator or similar fiduciary of
itself or of all or a substantial part of its property or calls a
meeting of its creditors, (ii) admits in writing its inability, or
is generally unable, to pay its debts as they become due or ceases

foregoing;

     (b)  any Lien in any of the Collateral, granted or intended by
the Loan Documents to be granted to Lender, ceases to be a valid,
enforceable, perfected, first priority Lien (or a lesser priority
if expressly permitted pursuant to Section 6 of the Loan
Authorization Agreement) subject only to Permitted Liens;

     (c)  the issuance of any levy, assessment, attachment, seizure
or Lien, other than a Permitted Lien, against any of the Collateral
which is not stayed or lifted within thirty (30) calendar days;

     (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 had or could reasonably be expected to have a Material
Adverse Effect and such litigation is not withdrawn or dismissed
within thirty (30) calendar days of the filing thereof;

     (f)  any default or event of default under the Loan Documents;

     (g)  any failure to comply with any terms of the Loan
Authorization Agreement;

     (h)  any material provision of any Loan Document or this
Agreement for any reason ceases to be valid, binding and
enforceable in accordance with its terms;

     (i)  any event which has had or could reasonably be expected
to have a Material Adverse Effect; or

Export-Related Borrowing Base.

2.12  Insurance. Borrower will at all times carry property,
liability and other 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 as they became due and
payable.  Borrower may, however, defer payment of any 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, and any material
development in, the proceedings; (c) posts bonds or takes any other
steps required to keep the contested taxes from becoming a Lien
upon any of the Collateral; and (d) maintains adequate reserves
therefor in conformity with GAAP.

2.14  Compliance with Laws. Borrower represents and warrants that
it has complied in all material respects with all provisions of all
applicable laws and regulations, including those relating to
Borrower's ownership of real or personal property, the conduct and

taxes, ERISA and other employee matters, safety and environmental
matters.

2.15  Negative Covenants.  Without the prior written consent of Ex-
Im Bank and Lender, Borrower shall not (a) merge, consolidate or
otherwise combine with any other Person; (b) acquire all or
substantially all of the assets or capital stock of any other
Person; (c) sell, lease, transfer, convey, assign or otherwise
dispose of any of its assets, except for the sale of Inventory in
the ordinary course of business and the disposition of obsolete
equipment in the ordinary course of business; (d) create any Lien
on the Collateral except for Permitted Liens; (e) make any material
changes in its organizational structure or identity; or (f) enter
into any agreement to do any of the foregoing.

2.16  Reborrowings and Repayment Terms.  (a)  If the Loan Facility
is a Revolving Loan Facility, provided that Borrower is not in
default under any of the Loan Documents, Borrower may borrow, repay
and reborrow amounts under the Loan Facility until the close of
business on the Final Disbursement Date.  Unless the Revolving Loan
Facility is renewed or extended by Lender with the consent of Ex-Im
Bank, Borrower shall pay in full the outstanding Loan Facility
Obligations 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 remittances it
may receive in payment or on account of the Export-Related Accounts
Receivable or any other Collateral, in precisely the form received
(except for the endorsement of Borrower where necessary).  Pending
such deposit, Borrower 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.

2.17  Cross Default.  Borrower shall be deemed in default under the
Loan Facility if Borrower fails to pay when due any amount payable
to Lender under any loan or other credit accommodations to Borrower
whether or not guaranteed by Ex-Im Bank.

2.18  Munitions List.  If any of the Items are articles, services,
or related technical data that are listed on the United States
Munitions List (part 121 of title 22 of the Code of Federal
Regulations), Borrower shall send a written notice promptly, but in
any event within five (5) Business Days, of Borrower learning
thereof to Lender describing the Items(s) and the corresponding
invoice amount.

2.19  Suspension and Debarment, etc.  On the date of this Agreement
neither Borrower nor its Principals are (a) debarred, suspended,
proposed for debarment with a final determination still pending,
declared ineligible or voluntarily excluded (as such terms are
defined under any of the Debarment Regulations referred to below)
from participating in procurement or nonprocurement transactions
with any United States federal government department or agency
pursuant to any of the Debarment Regulations or (b) indicted,
convicted or had a civil judgment rendered against Borrower or any
of its Principals for any of the offenses listed in any of the
Debarment Regulations.  Unless authorized by Ex-Im Bank, Borrower
will not knowingly enter into any transactions in connection with
the Items with any person who is debarred, suspended, declared
ineligible or voluntarily excluded from participation in
procurement or nonprocurement transactions with any United States
federal government department or agency pursuant to any of the
Debarment Regulations.  Borrower will provide immediate written
notice to Lender if at any time it learns that the certification
set forth in this Section 2.19 was erroneous when made or has
become erroneous by reason of changed circumstances.
