RE: Change to Concentration Limits

Dear Dan:

You requested Wells Fargo make a change to the customer concentration limits as defined in the Third Amended and Restated Credit Agreement dated December 30, 2005. This provision is detailed in Section 1.1, definition of Eligible Accounts, item (xii). Currently that section allows for [***] to be eligible up to 25% of all Accounts and [***] to be eligible up to 20% of all Accounts. You requested the concentration limit for those accounts, as well as that for [***] to be increased to 35%.

Effective with this letter, Section 1.1, Eligible Accounts (xii) is replaced in its entirety as follows:

“That portion of the aggregate Accounts of a single customer owed to all Borrowers in the aggregate that exceeds 15% of all Accounts of all Borrowers in the aggregate; provided, however, that for the customers listed below, such limit shall instead be the greater of the foregoing or the amount set forth opposite such customer in the following table:

CustomerConcentration Limit

[***]                    35%

[***]                    35%

[***]                    35%”

Please sign below indicating your acknowledgement and agreement with this change and return a signed copy of this letter to my attention.

As always, please let me know if you have any questions.

Sincerely,

[***]
