          NOW, THEREFORE, in consideration of the premises and the covenants
hereinafter contained, it is agreed as follows (it being understood that the
agreement below of Goldman, Sachs & Co. applies solely to the September

and inserting, in lieu of each such reference, "July 1, 2005";

          (b) by deleting the references to "July 1, 2005" in the second
sentence of Section 2(a), and in Section 3(c)(i), and inserting, in lieu of each
such reference, "September 1, 2005"; and

          (c) by deleting clause (ii) of the first sentence of Section 2(d) and
inserting, in lieu of such clause, the following: "(ii) such Exchange
Registration Statement or Shelf Registration Statement has not become effective

or".

           SECTION 2.      EFFECT ON REGISTRATION RIGHTS AGREEMENTS.

of similar import, shall mean and be a reference to such Registration Rights
Agreement as amended hereby.

          (b) Except as specifically amended above in connection herewith, each
Registration Rights Agreement shall remain in full force and effect and is
hereby ratified and confirmed.

          (c) The execution, delivery and effectiveness of this Amendment shall
not, except as expressly provided herein, operate as a waiver of any right,
power or remedy of the Original Investors or the Holders under the Registration
Rights Agreements or any document executed in connection therewith.

           SECTION 3.      GOVERNING LAW. THIS AMENDMENT AND THE OBLIGATIONS
ARISING HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE
WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO THE CONFLICT OF LAWS

           SECTION 4.      COUNTERPARTS. This Amendment may be executed in any
number of separate counterparts, each of which shall collectively and separately
constitute one agreement.

           IN WITNESS WHEREOF, this Amendment has been duly executed as of the
date first written above.
