complete:


                   A. CORPORATE POWER AND AUTHORITY. Each Borrower has all

this Amendment and the performance of the Amended Agreement have been duly
authorized by all necessary corporate action on the part of each of the
Borrowers.

                   C. NO CONFLICT. The execution and delivery by Borrowers of
this Amendment and the performance by Borrowers of the Amended Agreement do not
and will not (i) violate any provision of any law or any governmental rule or
regulation applicable to any Borrower or any of their respective Subsidiaries,
the Certificate or Articles of Incorporation or Bylaws or Certificate of
Formation or Operating Agreement, as applicable, of any Borrower or any of its
Subsidiaries or any order, judgment or decree of any court or other agency of

with, result in a breach of or constitute (with due notice or lapse of time or
both) a default under any Contractual Obligation of any Borrower or any of its

stockholders or any approval or consent of any Person under any Contractual
Obligation of any Borrower or any of its Subsidiaries.

                   D. GOVERNMENTAL CONSENTS. The execution and delivery by each
Borrower of this Amendment and the performance by the Borrowers of the Amended
Agreement and the transactions contemplated by this Amendment do not and will
not require any registration with, consent or approval of, or notice to, or
other action to, with or by, any federal, state or other governmental authority
or regulatory body.

                   E. BINDING OBLIGATION. This Amendment and the Amended
Agreement have been duly executed and delivered by each Borrower and is the
legally valid and binding obligations of the Borrowers, enforceable against the
Borrowers in accordance with their respective terms, except as may be limited by

respects on and as of the First Amendment Effective Date to the same extent as

and warranties specifically relate to an earlier date, in which case they were
true, correct and complete in all material respects on and as of such earlier
date.


                   G. ABSENCE OF DEFAULT. No event has occurred and is
continuing or will result from the consummation of the transactions contemplated
by this Amendment that would constitute an Event of Default or a Potential Event
of Default.
