requests for Advances or preclude LGE from exercising any rights available to

require further notice by LGE of LGE's intent to require strict adherence to the
terms of the Agreement in the future. Any such actions shall not in any way
affect the ability of LGE, in its discretion, to exercise any rights available
to it under this Agreement or under any other agreement, whether or not LGE is
party, relating to the Borrower.

prohibition or unenforceability without invalidating the remaining provisions
hereof in that jurisdiction or affecting the validity or enforceability of such

any provision hereof.

                         ----------------
provided herein, this Agreement and the other documents described or
contemplated herein embody the entire Agreement and understanding among the
parties hereto and thereto and supersede all prior agreements (including the
commitment letter which has previously been delivered), understandings, and
conversations relating to the subject matter hereof and thereof and may not be
