                  "(ii) as of any date prior to the date of termination of the

                  the Limited Partners holding fifty percent (50%) or more of
                  the interests of such Limited Partnership or General Partner,
                  as the case may be, shall have affirmatively disapproved the
                  transactions contemplated by this Agreement or approved any
                  Acquisition Proposal;"

         6.       The following subsection (f) is hereby added to Section 11.1:

                  "(f) By Sellers or Enstar, at any time prior to the Closing,
                  if any Seller or Enstar receives a proposal for an Acquisition
                  Proposal (i) that Enstar determines in its good faith judgment
                  is more favorable to the Limited Partners than is this
                  Agreement, and (ii) as a result of which Enstar determines in
                  good faith, based upon the advice of its counsel, that it is
                  obligated by its fiduciary obligations under applicable law to
                  terminate this Agreement."

         7.       Section 11.2(a) is hereby amended to read, in its entirety, as

                  Section 11.2, in the event that either (i) this Agreement is
                  terminated pursuant to Section 11.1(f), or (ii) (A) this
                  Agreement is terminated by Buyers pursuant to Section 11.1(e),
                  and (B) as of the date of such termination, any Limited
                  Partnership's or General Partner's Limited Partners shall have
                  given their consent to an Acquisition Proposal submitted by a
                  third party; and, in the case of termination pursuant to
                  either clause (i) or (ii) hereof, Buyers shall have performed
                  and complied in all material respects with all covenants and
                  agreements required to be performed or complied with by them
                  under this Agreement during the period prior to the first to
                  occur of (x) the termination of this Agreement pursuant to
                  Section 11.1(f), (y) the date on which any Limited
                  Partnership's or General Partner's Limited Partners shall have
                  either disapproved the transactions contemplated by this


   3

                  Agreement or given their consent to an Acquisition Proposal
                  submitted by a third party, or (z) the first-occurring date of
                  termination of the Voting Period of any Limited Partnership or
                  General Partner during which the Limited Partner Consents for
                  such Limited Partnership or General Partner shall not have
                  been obtained. Sellers shall pay the Breakup Fee to Buyers by
                  wire transfer of immediately available funds or by certified
                  check (in accordance with Buyers' written instructions) within
                  five (5) business days following the date of termination
                  pursuant to Section 11.1(e) or (f). For purposes hereof, the
                  "Breakup Fee" with respect to any Seller means a pro rata
                  portion of the aggregate amount of $1,500,000, which shall be
                  determined by allocating the amount of $1,500,000 among
                  Sellers based on the allocation of the aggregate Purchase
                  Price among Sellers.

         8.       Schedule 1.1 is hereby amended by deleting the column bearing
                  the heading "Indemnity Fund."

         9.       It is hereby agreed that (i) where the Purchase Agreement
                  contains capitalized terms that are not defined therein
                  (including without limitation the terms "Business Day,"
                  "Franchise," "Franchise Area" and "Interest"), any such term
                  shall have the same meaning as if used with initial lowercase
                  letters, unless otherwise dictated by the context; (ii) where
                  the context so requires, the term "Buyer" or "Seller" shall
                  refer to the plural of such term; (iii) references to "Buyer"
                  or "Seller" are intended to refer to the applicable Buyer or
                  Seller, as required by the context; and (iv) "General
                  Partnership" means each of the Sellers that is identified in
                  the preamble hereto as a general partnership.
