extent that such representations and warranties specifically refer to an earlier
date, in which case they shall be true and correct in all material respects as
of such earlier date and (b) no Default exists as of the date hereof.

all references to a “Loan Document” in the Credit Agreement and the other Loan
Documents (including all such references in the representations and warranties
in the Credit Agreement and the other Loan Documents) shall be deemed to include
this Amendment.

9.    Counterparts; Delivery. This Amendment may be executed in any number of
counterparts, each of which when so executed and delivered shall be an original,

executed counterpart of a signature page of this Amendment or any other document
required to be delivered hereunder, by fax transmission or e-mail transmission
