1.1.
The definition of “Revolving Loan Termination Date” appearing in Section 1.1 of

reasonableness, good
faith and fair dealing), and (ii) no Default or Event of Default has occurred
and is

3.2.     Upon the effectiveness of this Amendment and after giving effect

4.2.     Except as specifically modified above, the Credit Agreement and all
other documents,
instruments and agreements executed and/or delivered in connection therewith,
shall
remain in full force and effect, and are hereby ratified and confirmed.

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

4.3.     The execution, delivery and effectiveness of this Amendment shall not
