Capitalized terms used herein and not otherwise defined herein shall have the
same meanings as defined in the Agreement.

Except as expressly amended hereby, the Agreement shall remain in full force and
effect in accordance with the original terms thereof and is ratified and
confirmed.

The agreements herein contained are limited specifically to the matters set

waiver of any other provision of the Agreement or any Default or Event of

The Company hereby represents and warrants that, after giving effect to this
SECOND AMENDMENT, (1) no Default or Event of Default exists under the Agreement

with respect to these covenants or any other covenants, those requests shall be
evaluated by the Lender when formally requested, in writing, by the Company.

This SECOND AMENDMENT may be executed in one or more counterparts, each of which
shall constitute an original, but all of which when taken together shall

effective when duly executed counterparts hereof which, when taken together,
bear the signatures of each of the parties hereto shall have been delivered to
the Lender.
