     6.  Waiver.  Neither the failure nor any delay by a party in exercising any
     right,  power  or  privilege  under this Agreement will operate as a waiver
     thereof,  nor  shall  any  single  or partial exercise thereof preclude any
     other  or  further  exercise thereof or the exercise of any right, power or
     privilege  hereunder.

     7.  No  Third Party Beneficiaries. This Agreement is solely for the benefit

     between  the parties with respect to the subject matter hereof and thereof.

     out  of  or  in  connection with, this Agreement may be brought only in the
     Court  of  Chancery  of the State of Delaware or a federal court located in
     Delaware,  and  each party irrevocably consents to the jurisdiction of such
     courts  (and of the appellate courts therefrom) in any such suit, action or
     proceeding  and  irrevocably  waives  any objection it may now or hereafter
     have  to  the laying of venue of any such suit, action or proceeding in any
     such  court or that any such suit, action or proceeding brought in any such
     court  has  been  brought  in  an  inconvenient  forum.

     11.  Governing  Law.  This  Agreement shall be governed by and construed in
     accordance  with the laws of the State of Delaware without giving effect to
     any conflict of law rules that would otherwise cause the application of the
