date; and

     (b)  After giving effect to this Second Amendment, no Default or Event of
Default has occurred and is continuing.

     5.  Effect of Second Amendment.  On and after the date this Second
         --------------------------

the Credit Agreement to "hereof," "hereunder," "herein," "hereby" and each other

other similar reference, shall refer to the Credit Agreement as amended hereby,
and as the same may be further amended, restated or supplemented from time to

and the other Loan Documents effective as of the date hereof. To induce the
Lenders to enter into this Second Amendment and to continue to make advances
pursuant to the Credit Agreement, the Borrower acknowledges and agrees that, as
of the date hereof and after giving effect to the terms hereof, there exists no
right of offset, defense, counterclaim, claim or objection in favor of the
Borrower arising out of or with respect to any of the obligations arising under
the Credit Agreement or the other Loan Documents.

     7.  Counterparts.  This Second Amendment may be executed in any number of
         ------------

of which

                                       2

instrument.

     8.  Condition to Effectiveness of Second Amendment.  This Second Amendment
         ----------------------------------------------
shall not become effective or have any force or effect until counterparts of
this Second Amendment have been executed on behalf of the Borrower and those
Lenders constituting the Required Lenders under the terms of the Credit
Agreement, and all such executed counterparts shall have been delivered to the
Administrative Agent.

     9.  Miscellaneous.  This Second Amendment shall be construed in accordance
         -------------
