Nothing herein will limit or affect, or give rise to any liability, to the extent required for the discharge of the fiduciary obligations described in this Section 24.

Section 25.

Representation by Counsel. Each Party acknowledges that it has been represented by, or provided a reasonable period of time to obtain access to and advice by, counsel with this Agreement and the transactions contemplated herein. Accordingly, any rule of law or any legal decision that would provide any Party with a defense to the enforcement of the terms of this Agreement against such Party based upon lack of legal counsel shall have no application and is expressly waived.
