the validity or enforceability of the indebtedness evidenced by the Note; (b)
the liens, security interests, assignments and conveyances effected by the

consents granted herein are effective only in the specific instance and for the
purposes for which given.

     12.  This Amendment shall be governed by the laws of the State of Alabama.
