indemnify and hold harmless the Escrow Agent from any and all claims,
liabilities, costs or expenses in any way arising from or relating to the duties
or performance of the Escrow Agent hereunder other than any such claim,
liability, cost or expense to the extent the same shall (a) have been tax

of the parties hereto, and their respective successors and permitted assigns and
shall be governed by the laws of the State of New York without giving effect to
principles governing the conflicts of laws. A facsimile transmission of these
instructions signed by the Escrow Agent shall be legal and binding on all
parties hereto.

         14.      Capitalized terms used herein and not otherwise defined herein
