obligation, enforceable against it in accordance with its terms.

constitute a single contract. This Agreement shall become effective when the
Collateral Agent shall have received counterparts of this Agreement that, when
taken together, bear the signatures of the Borrower and the Collateral Agent.
Delivery of an executed signature page to this Agreement by facsimile

as such provision is held to be invalid, illegal or unenforceable, but the
validity, legality and enforceability of the remaining provisions contained
herein and in the Pledge Agreement shall not in any way be affected or impaired.

invalid, illegal or unenforceable provisions with valid provisions the economic
effect of which comes as close as possible to that of the invalid, illegal or
unenforceable provisions.
