AGREEMENT

NOW, THEREFORE, in consideration of the foregoing recitals and other good and
valuable consideration, the receipt and adequacy of which is hereby
acknowledged, and intending to be legally bound, the parties hereto agree as
follows:

1. Definitions. Capitalized terms used but not defined in this Amendment shall
have the meanings given to them in the Loan Agreement.

2. Amendments to Loan Agreement.

2.1 Section 2.1.2 Letter of Credit Sublimit. Section 2.1.2 of the Agreement is
hereby deleted and replaced with a placeholder stating [Intentionally Omitted].

2.2 Section 2.1.3 Foreign Exchange Sublimit. Section 2.1.3 of the Agreement is
hereby deleted and replaced with a placeholder stating [Intentionally Omitted].

2.3 Section 2.1.4 Cash Management Sublimit. Section 2.1.3 of the Agreement is
hereby deleted and replaced with a placeholder stating [Intentionally Omitted].

--------------------------------------------------------------------------------

2.4 Section 2.2 (Overadvances). Section 2.2 of the Loan Agreement is hereby
deleted and replaced with the following:

Overadvances If, at any time, the sum of (a) the outstanding principal amount of
any Advances (such sum being an “Overadvance”) exceeds the lesser of either the
Revolving Line or the Borrowing Base, Borrower shall immediately pay to Bank in
cash such Overadvance. Without limiting Borrower’s obligation to repay Bank any
amount of the Overadvance, Borrower agrees to pay Bank interest on the
outstanding amount of any Overadvance, on demand, at the Default Rate.

2.5 Section 2.4 (Fees). Section 2.4(b) of the Loan Agreement is hereby deleted
and replaced with a placeholder stating [Intentionally Omitted]. Section 2.4(d)
of the Loan Agreement is hereby deleted and replaced with the following:

A fee (the “Unused Revolving Line Facility Fee”), payable monthly, in arrears,
on a calendar year basis, in an amount equal to 0.375 percent (0.375%) per annum
of the average unused portion of the Revolving Line. The unused portion of the
Revolving Line, for purposes of this calculation, shall equal the difference
between (x) the Revolving Line amount (as it may be reduced from time to time)
and (y) the average for the period of the daily closing balance of the Revolving
Line outstanding. Borrower shall not be entitled to any credit, rebate or
repayment of any Unused Revolving Line Facility Fee previously earned by Bank
pursuant to this Section notwithstanding any termination of the Agreement or the
suspension or termination of Bank’s obligation to make loans and advances
hereunder;

2.6 Section 4.1 (Security Interest). Section 4.1 of the Loan Agreement is hereby
deleted and replaced with the following:

Grant of Security Interest. Borrower hereby grants Bank, to secure the payment
and performance in full of all of the Obligations, a continuing security
interest in, and pledges to Bank, the Collateral, wherever located, whether now
owned or hereafter acquired or arising, and all proceeds and products thereof.
Borrower represents, warrants, and covenants that the security interest granted
herein is and shall at all times continue to be a first priority perfected
security interest in the Collateral (subject only to Permitted Liens that may
have superior priority to Bank’s Lien under this Agreement). If Borrower shall
acquire a commercial tort claim, Borrower shall promptly notify Bank in a
writing signed by Borrower of the general details thereof and grant to Bank in
such writing a security interest therein and in the proceeds thereof, all upon
the terms of this Agreement, with such writing to be in form and substance
reasonably satisfactory to Bank.

Notwithstanding the foregoing, it is expressly acknowledged and agreed that the
security interest created in this Agreement only with respect to EX-IM Eligible
Foreign Accounts (as such term is defined in the EXIM Loan Agreement) is subject
to and subordinate to the security interest granted to Bank in the EXIM Loan
Agreement with respect to such EX-IM Eligible Foreign Accounts.

 

2

--------------------------------------------------------------------------------

If this Agreement is terminated, Bank’s Lien in the Collateral shall continue
until the Obligations (other than inchoate indemnity obligations) are repaid in
full in cash. Upon payment in full in cash of the Obligations and at such time
as Bank’s obligation to make Credit Extensions has terminated, Bank shall, at
Borrower’s sole cost and expense, release its Liens in the Collateral and all
rights therein shall revert to Borrower.

Borrower acknowledges that it previously has entered, and/or may in the future
enter, into Bank Services Agreements with Bank. Regardless of the terms of any
Bank Services Agreement, Borrower agrees that any amounts Borrower owes Bank
thereunder shall be deemed to be Obligations hereunder and that it is the intent
of Borrower and Bank to have all such Obligations secured by the first priority
perfected security interest in the Collateral granted herein (subject only to
Permitted Liens that may have superior priority to Bank’s Lien in this
Agreement).

Borrower agrees that, unless otherwise agreed in a writing signed by Bank and
Borrower (a) the security interest granted herein by Borrower shall survive the
termination of this Agreement and shall terminate only upon the termination of
all Bank Services Agreements, and (b) if, on the effective date of the
termination of this Agreement, there are any outstanding Letters of Credit, then
on such date Borrower shall provide to Bank cash collateral in an amount equal
to 105% — use if the letter of credit is denominated in U.S. Dollars of the
Dollar Equivalent of the face amount of all such Letters of Credit plus all
interest, fees, and costs due or to become due in connection therewith (as
estimated by Bank in its good faith business judgment), to secure all of the
Obligations relating to such Letters of Credit.

2.7 Section 9.1(c) (Letters of Credit). Section 9.1(c) of the Loan Agreement is
hereby deleted and replaced with the following:

(c) for any Letters of Credit, demand that Borrower (i) deposit cash with Bank
in an amount equal to 105% of the Dollar Equivalent of the aggregate face amount
of all Letters of Credit remaining undrawn (plus all interest, fees, and costs
due or to become due in connection therewith (as estimated by Bank in its good
faith business judgment)), to secure all of the Obligations relating to such
Letters of Credit, as collateral security for the repayment of any future
drawings under such Letters of Credit, and Borrower shall forthwith deposit and
pay such amounts, and (ii) pay in advance all letter of credit fees scheduled to
be paid or payable over the remaining term of any Letters of Credit;

2.8 Section 12.9 (Survival). Section 12.9 of the Loan Agreement is hereby
deleted and replaced with the following:

Survival. All covenants, representations and warranties made in this Agreement
continue in full force until this Agreement has terminated pursuant to its terms
and all Obligations (other than inchoate indemnity obligations and any other

 

3

--------------------------------------------------------------------------------

obligations which, by their terms, are to survive the termination of this
Agreement) have been paid in full and satisfied. The grant of security interest
by Borrower in Section 4.1 shall survive until the termination of all Bank
Services Agreements, and the obligation of Borrower in Section 12.3 to indemnify
Bank shall survive until the statute of limitations with respect to such claim
or cause of action shall have run.
