INDEMNITIES:       The  Credit  Agreement  shall  contain  customary  provisions
                   protecting  and  indemnifying  the  Lenders  in the  event of
                   unavailability  of  funding,  illegality,   increased  costs,
                   capital  adequacy  charges  and  funding  losses,  and  shall
                   provide  for  a  withholding   tax   gross-up,   and  general
                   indemnification of the Administrative Agent, by the Borrower.

EXPENSES:          The Borrower will pay all costs and expenses  incurred at any
                   time  by  the   Administrative   Agent  (including,   without
                   duplication,  reasonable  attorneys' fees and allocated costs
                   of internal  counsel) in connection  with the preparation and
                   delivery of the Credit  Agreement and all related  documents,
                   and in  the  negotiation,  closing,  and  enforcement  of the
                   Facility,  regardless  of whether  the  Facility closes.  The
                   Borrower  shall  also  pay  all  costs  and  expenses  of the
                   Administrative  Agent  associated  with  amendments and other
                   changes to the Credit  Agreement,  and all costs and expenses
                   of the Lenders in the  collection of the  obligations  of the
                   Borrower (including  reasonable attorneys' fees and allocated
                   costs  of  internal  counsel).  


DOCUMENTATIONS:    Closing is subject to (among other conditions  precedent) the
                   receipt by the  Administrative  Agent and the Lenders of loan
                   documentation in form and substance satisfactory to them.

GOVERNING LAW:     State of New York.



This  Summary of Terms and  Conditions  (the "Term  Share")  does not attempt to
describe  all of the terms and  conditions  that  would  pertain  to the  Senior
Facility,  nor do its terms  suggest  the  specific  phrasing  of  documentation
clauses.  This term  sheet is not a  commitment  to  provide,  close or fund the
Senior Facility.  Instead,  it is intended to outline certain points of business
understanding  around which the Senior Facility will be structured.  The closing
of any financial transaction relating to the Senior Facility would be subject to
definitive  loan  documentation  manually  acceptable  to the  Borrower  and the
Administrative Agent and would include various conditions  precedent,  including
without limitations the conditions set forth above.
