     (b) the First Amendment to Credit Agreement shall have become effective.

     3. Miscellaneous.

     (a) The Pledge Agreement and the obligations of the Pledgors thereunder and under the

effect according to their terms.

26

 

     (b) Upon the effectiveness of this First Amendment, each reference in the Pledge

reference to the Pledge Agreement, as affected and amended by this First Amendment.

     (c) Each Pledgor (a) acknowledges and consents to all of the terms and conditions of
this First Amendment, (b) affirms all of its obligations under the Loan Documents and (c)

     (i) Each Pledgor has taken all necessary action to authorize the execution,
delivery and performance of this First Amendment;

     (ii) This First Amendment has been duly executed and delivered by the Pledgors
and constitutes each of the Pledgors’ legal, valid and binding obligations,
enforceable in accordance with its terms, except as such enforceability may be
subject to (A) bankruptcy, insolvency, reorganization, fraudulent conveyance or
transfer, moratorium or similar laws affecting creditors’ rights generally and (B)
general principles of equity (regardless of whether such enforceability is
considered in a proceeding at law or in equity); and

     (iii) No consent, approval, authorization or order of, or filing, registration
or qualification with, any court or governmental authority or third party is
required in connection with the execution, delivery or performance by any Pledgor of
this First Amendment.

     (e) The Pledgors represent and warrant to the Lenders that (i) the representations and
warranties of the Pledgors set forth in Section 3 of the Pledge Agreement and in
each other Loan Document are true and correct in all material respects as of the date hereof
with the same effect as if made on and as of the date hereof, except to the extent such
representations and warranties expressly relate solely to an earlier date and (ii) no event
has occurred and is continuing which constitutes a Default or an Event of Default.

     (f) This First Amendment may be executed in any number of counterparts, each of which
when so executed and delivered shall be an original, but all of which shall constitute one
and the same instrument. Delivery of an executed counterpart of this First Amendment by
telecopy shall be effective as an original and shall constitute a representation that an
executed original shall be delivered.

     (g) THIS FIRST AMENDMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL
BE GOVERNED BY AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW
YORK.
