Section 1.2(a)(v) of Amendment No. 5 provides that Borrowers may, at their option, increase the amount of the Maximum Credit, subject to certain conditions.

The conditions to such increase include that a Lender or Eligible Transferee increase or provide, as the case may be, an additional Commitment so that the aggregate amount of the Commitments equal the amount of the Maximum Credit as requested to be increased.

Accordingly, as of the date hereof ,Wachovia shall increase its Commitment by $30,000,000 (the “Commitment Increase”), so that its aggregate Commitment is $90,000,000, provided, that, as of the date of such Commitment Increase, each of the following conditions precedent is satisfied as determined by Wachovia: (a) Wachovia has received an original executed Assignment and Acceptance Agreement from Wells Fargo Bank, N.A.

On and after the effectiveness of the Commitment Increase, all references to the term “Maximum Credit” in the Loan Agreement or any of the other Financing Agreements shall be amended to mean $255,000,000.

This letter agreement shall be governed by the internal laws of the State of Illinois but excluding any principles of conflicts of law or other rule of law that would cause the application of the law of any jurisdiction other than the State of Illinois.

This letter agreement may be executed in any number of counterparts, each of which shall be an original, but all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of this letter agreement by telefacsimile shall have the same force and effect as the delivery of an original executed counterpart of this
