                                       4
<PAGE>
 
Agreement and the Plan, Prior to April 30, 1998, RG&E and GE Capital shall agree
on a Schedule of Excluded Assets.

          (5) The tangible assets included in the Purchased Assets shall be
purchased "AS IS" and "WHERE IS", but RG&E shall have inspected and examined
those assets to determine their condition and to ensure that the Purchased
Assets are adequate and suitable in accordance with general industry practices
for the purpose currently used and intended to be used. RG&E shall have
completed any such inspection, examination or due diligence by not later than
5:00 P.M. (EDT) on April 30, 1998 (the "Due Diligence Date"). If by the Due
Diligence Date, GE Capital and the Debtor shall not have received written notice
of any deficiency, then RG&E shall be deemed to be satisfied with its
inspection, examination and due diligence findings. However, if GE Capital and
the Debtor by such time shall have received a written notice of deficiency, then
RG&E and GE Capital shall meet and negotiate in good faith to reach a
commercially reasonable solution to such deficiency. Debtor shall use its
reasonable best efforts to maintain, or cause to be maintained, the Purchased
Assets in their condition as of the execution and delivery of this Settlement
Agreement, ordinary wear and tear and any effect resulting from the operation of
the Facility at the request of RG&E excepted.


                                       5
<PAGE>
 
          (6)  Each of Debtor and Kamine Affiliates covenants it will promptly
furnish, or cause to be furnished, to RG&E and its representatives all data and
information relating to the Purchased Assets that may be reasonably requested
through the Effective Date. Debtor shall, through the Effective Date upon the
reasonable request of RG&E afford RG&E reasonable access to the Facility and the
Facility Property. Debtor shall, through the Effective Date upon the reasonable
request of RG&E, cooperate, consult with and assist RG&E and its representatives
with respect to any inspection, examination or review of the Purchased Assets.
At the request of RG&E and upon at least one business day advance notice,
through the Effective Date the Debtor will from time to time give or cause to be
given to RG&E and its representatives (a) access during normal business hours to
all of the Purchased Assets and related operations and (b) all information
concerning the Purchased Assets as RG&E may reasonably request.

          (7) At closing, Debtor shall execute or use its reasonable best
efforts to obtain (as applicable), any written consents, approvals,
authorizations, assignments, deeds, bills of sale or other instruments of
conveyance (collectively "Consents and Instruments of Transfer") in


                                       6
<PAGE>
 
form reasonably satisfactory to RG&E, to transfer to RG&E, and vest in RG&E good
and marketable title to all of the Debtor's right, title and interest in and to
the Purchased Assets, which shall by order of the Bankruptcy Court be free and
clear of liens, encumbrances or other Claims under Code (S) 363(f), and to
substitute RG&E as lessee of any Purchased Assets under lease to Debtor. It is
expressly understood and agreed that to the extent RG&E or its designee becomes
the owner, lessee or entity entitled to become the owner of the real property on
which the Greenhouse is situated under an installment sale agreement or other
agreement with the IDA, RG&E or such designee as owner of the real property
shall at the election of GE Capital subdivide and convey such real property or
(as lessee of the real property) shall enter into a lease thereof for a term to
be mutually agreed upon at a nominal rental, as applicable, for the benefit of
GE Capital and/or its designee-owner of the Greenhouse.

          To the extent that RG&E reasonably determines, before or after the
closing, that any additional Consents and Instruments of Transfer are necessary
in order to vest all of Debtor's right, title and interest in the Purchased
Assets in RG&E, Debtor shall execute or use its reasonable best efforts to
obtain any such Consent or Instrument of Transfer. Such Consents and Instruments
of Transfer may not


                                       7
<PAGE>
 
require any change in the terms and conditions of the Global Settlement
Agreement unless consented to by the parties. GE Capital and the Kamine
Affiliates shall use their respective reasonable best efforts (without incurring
any significant expenses to do so) to assist the Debtor in respect of the
performance of its obligations pursuant to paragraph 7 hereof.

          (8) It is expressly agreed and understood that, RG&E shall not
assume, pay or discharge, or in any respect be liable for any liability,
obligation, commitment or expense of Debtor or of any Kamine Affiliate
attributable to the Purchased Assets including any federal, state or local sales
taxes, accrued up to closing or relating to the transfer of the Purchased
Assets. At or after the closing, at the request of RG&E and upon five business
days advance notice, GE Capital shall execute and deliver UCC-3 termination
statements and discharges and/or releases of liens of mortgages and other
instruments and documents, in form and substance satisfactory to RG&E and its
counsel evidencing the release, discharge and termination of all liens or
encumbrances held by GE Capital on the Purchased Assets. Debtor has paid or will
pay all taxes, levies and assessments required to be paid by Debtor as of the
Effective Date, the non-payment of which would result in the


                                       8
<PAGE>
 
imposition of a lien or a charge against the Purchased Assets or RG&E as owner
of the Purchased Assets.

          (9)   Any item of Purchased Assets which includes a written or oral
obligation which arises or accrues after the Effective Date shall be set forth
on a separate schedule prior to closing. RG&E shall in no event assume or be
liable for any Claim, liability or legal obligation which accrues on or prior to
the Effective Date not specifically assumed in writing.

          (10)  Conditions To Closing.

                The obligation of the parties hereto to the transactions
          contemplated hereby shall be the satisfaction or waiver of each of

          rights of third parties to the Purchased Assets that are owned by

          amend the installment sale agreement with the Debtor to reflect terms
          acceptable to RG&E and consented to the assignment of such agreement,
          as amended, to RG&E;

                (iii) absence of any material change in the condition of the
          Purchased Assets (ordinary wear and tear from April 30, 1998 and
          any effect from the operation of this facility prior to the Effective
          Date at the request of RG&E excepted), including without limitation
          any damage, destruction or loss, whether or not covered by insurance,
          which has or will have a materially adverse effect on the Purchased
          Assets; and

                (iv)  Debtor shall have delivered to RG&E the Consents and
          Instruments of Transfer in form and substance reasonably satisfactory
          to RG&E; and

          Debtor shall not recommend a Competitive Bid unless. (a) the value of
the Competitive Bid is at least $1 million in excess of the Purchase Price; (b)
the competing bidder makes a deposit with Debtor of at least $1,600,000 upon
submission of a Competing Bid; (c) the Competitive Bid is accompanied by recent,
written financial statements or other financial disclosure which demonstrates
the capability and financial wherewithal of the competing bidder to close and
consummate the Competitive Bid; and (d) the transaction

is not subject to or conditioned upon the obtaining of financing.

          In the event a Competitive Bid is timely made which Debtor and GE
Capital jointly determine to be a higher and better offer, RG&E may improve its
initial bid at any time prior to the conclusion of the Hearing so as to match
the Competitive Bid.  If so matched, then additional bidding procedures that are
not inconsistent with the foregoing may be determined by the Bankruptcy Court at
or before the Hearing.

          In the event there is a successful Competitive Bid, then the
difference (i) between the successful higher bid and (ii) $15 million plus
interest on $15 million from July 1, 1998 to the Effective Date calculated at
the annual rate of 7%, shall be applied first to reduce the $10 million cash
payment dueon the Effective Date, and then to payments in the Payment Plan in
direct order of maturity.
