matters in respect of monies deposited in, borrowed from, or investments made in
connection with, the  Pool. ASFC may contract with one or more other persons for

the contrary, no provision of this Agreement or any amendment or supplement
hereto shall be deemed to impose any duty or obligation on ASFC to perform any

future law shall be unlawful, or which shall be beyond the corporate powers,
authorization or qualifications of ASFC.

      Section 6.3 Maintenance of Records

expenses of collection, including, without limitation, reasonable attorneys'
fees, expenses and disbursements.  No course of dealing and no delay on the part
of any holder of any note or any instrument relating to such note or to this
Agreement in exercising any right contained therein shall operate as a waiver
thereof or otherwise prejudice such holder's rights, powers or remedies. No
right, power or remedy conferred by this Agreement or by any instrument upon any
holder thereof shall be exclusive of any right, power or remedy referred to
herein or therein or now or hereafter available at law, in equity, by statute ro
otherwise.

defaulting party timely written notice specifying the nature of such alleged
default and what actions the aggrieved party has taken or is taking or proposes
to take with respect thereto.
      (b) if a party to this Agreement gives any notice or takes any other
actions with respect to a claimed default, such party will forthwith give
written notice thereof to all other Participants, describing the notice or
action and the nature of the claimed default.

                                  ARTICLE VIII

               In the event that an enforcement action against ASFC shall result
in the termination of the Pool, or the Pool shall be terminated for any other
reason, the Pool funds shall be distributed to Participants in satisfaction of
any deposit obligation under this Agreement including principal and interest.

power or privilege hereunder shall affect such right, power or privilege; nor
shall any single or partial exercise thereof or any abandonment or

further exercise thereof or of any other right, power or privilege.  The rights
