necessary that the signature of, or on behalf of, each party or that the
signature of all persons required to bind any party appear on each counterpart.
All counterparts shall collectively constitute a single counterpart containing
the respective signatures of, or on behalf of, each of the parties hereto. Any
signature page to any counterpart may be detached from such counterpart without
impairing the legal effect of the signatures thereon and thereafter attached to
another counterpart identical thereto except having attached to it additional
signature pages. Signatures hereto transmitted by facsimile or other electronic
medium shall be effective as originals.

represents that Borrower is not relying on any statement or representation other

its own judgment and advice of its attorneys.
