 the Borrower  or  Subordinated Lender  in  the  performance of  any  of  the
 material terms of this Agreement, or any instrument or agreement evidencing,
 securing  or  relating  to  the  Senior  Indebtedness,  all  of  the  Senior

  Lender.

 by the parties with the expectation and in reliance upon the assumption that
 the instruments and documents evidencing  the Senior Indebtedness are  valid
 and enforceable.  In  determining  whether to  enter  into  this  Agreement,
 Subordinated Lender has  assumed such validity  and enforceability, and  has
 agreed to  the  provisions contained  herein,  without relying  upon  any189

 permitted by law, that it shall  not initiate in any proceeding a  challenge
 to  the  validity  or  enforceability  of  the  documents  and   instruments
 evidencing the Senior Indebtedness, nor shall Subordinated Lender  instigate
 other parties to raise  any such challenges,  nor shall Subordinated  Lender
 participate in or otherwise assert any  such challenges which are raised  by
 other parties.  The foregoing notwithstanding,  in the event that any  other
 party is successful  in establishing the  invalidity or unenforceability  of
 any of the documents or instruments evidencing the Senior Indebtedness, then
 Subordinated Lender shall  be entitled to  the benefit of  such result,  and
 Subordinated Lender shall not  be bound by  the subordination provisions  of
 this Agreement to the extent of such invalidity or unenforceability.

      25.   Subrogation.  Subject   to  the   foregoing  provisions   hereof,

 failure shall, notwithstanding such provision contained herein, constitute a
 default with respect to the Subordinated  Indebtedness if and to the  extent

 the terms of the Subordinated Indebtedness.

      26.   Termination  of Agreement.   This  Agreement  shall  continue and

 Agreement shall continue to be effective, or be reinstated, as the ease  may
 be, if at  any time any  payment in respect  of any  Senior Indebtedness  is
 rescinded or must  otherwise be  restored or  returned by  Senior Lender  by
 reason  of  any  bankruptcy,  reorganization,  arrangement,  composition  or
 similar proceeding  or  as  a  result of  the  appointment  of  a  receiver,
 intervenor or conservator of, or trustee or similar officer for, Borrower or
 any substantial  part of  its property,  or otherwise,  all as  though  such
 payment had not been made.

 that such invalidity or  unenforceability shall not  affect the validity  or
 enforceability of any other provision hereof, and that this Agreement  shall

 contained herein.
