amended by this Amendment constitutes the legal, valid and binding obligation of
each of the Borrowers, enforceable against them in accordance with its terms,

other laws affecting creditors' rights generally and subject to general
principles of equity, regardless of whether considered in a proceeding in equity
or at law.

               (c) All representations and warranties of the Borrowers contained
in Article III of the Credit Agreement are true and correct as of the date
hereof (except for representations or warranties that expressly relate to an
earlier date, in which case such representations and warranties are true and
correct as of such earlier date).

OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.
