          Authority having jurisdiction of the Assets;

all material policies of title, property, fire, casualty, liability and other
forms of insurance of any kind relating to the Assets, including policy numbers,

at Seller's expense, a standard ALTA leasehold title insurance commitment in
Buyer's name, insuring good, marketable fee simple title in the Real Property
(the "Title Commitment") from an underwriter reasonably acceptable to Buyer (the
"Title Company"). If the Title Commitment shall reflect that Seller's interest
is not good, marketable and insurable, or shows any restrictions, covenants,
easements, agreements or encroachments unrelated to the IRB Obligations and that
are not acceptable to Buyer in its reasonable discretion, Buyer shall so notify
Seller within five (5) days of receipt of the Title Commitment and legible
copies of all exception documents and the Survey (as defined below). Seller
shall, at Seller's expense, cure any defects objected to by Buyer no later than
three (3) business days prior to the Closing. If such defects are not cured,
Buyer shall have the option to (a) agree to the Closing and accept title in its
existing condition, or (b) terminate this Agreement. As of the Closing, Seller
shall cause the Title Company to issue a title insurance policy at Seller's
expense in the amount of the Purchase Price (the "Title Insurance Policy") which
is satisfactory to Buyer and reflects the absence of any encumbrance or
exception objected to by Buyer, unless waived by Buyer, and including such

such other matters and certifications as are required by the Title Company to


                                       8
<PAGE>

objectionable to Buyer, Buyer will by written notice to Seller, within five (5)

matters to which Buyer reasonably objects.

of the IRB Documents, including the Lease, have previously been delivered by the
Seller to the Buyer. Such documents are in full force and effect, are binding
and enforceable against the Seller in accordance with their terms and have not
been modified or amended since the date of delivery to Buyer. To the best
knowledge of Seller, there has not occurred any event which would constitute a
breach of or default in the performance of any material covenant, agreement or

such a breach of material default.

inquiries concerning the business affairs and financial condition of the Buyer

     conduct of any business or operations thereon that have given or are likely
     to give rise to an unsatisfied on-site or off-site response, removal,

indemnify the Indemnified Party with respect to all elements of such claim. If
the Indemnifying Party assumes the defense of any such claim or legal
proceeding, the Indemnifying Party shall select counsel reasonably acceptable to
the Indemnified Party to conduct the defense of such claims or legal proceedings
and at the sole cost and expense of the Indemnifying Party shall take all steps
necessary in the defense or settlement thereof. The Indemnified Party shall
thereafter be entitled

                                       18
<PAGE>

to participate in and assume control of the defense of any such action if the
Indemnified Party has a reasonable basis for concluding that its interests would
be better served. The Indemnifying Party shall not consent to a settlement of,
or the entry of any judgment arising from, any such claim or legal proceeding,
without the prior written consent of the Indemnified Party (which consent shall
not be unreasonably withheld or delayed). The Indemnified Party shall be
entitled to participate in (but not control) the defense of any such action,
with its own counsel and at its own expense. If the Indemnifying Party does not
assume the defense of any such claim or litigation resulting therefrom within 30
days after the date such claim is made: (a) the Indemnified Party may defend
against such claim or litigation in such manner as it may deem appropriate,
including, but not limited to, settling such claim or litigation, after giving
notice of the same to the Indemnifying Party, on such terms as the Indemnified
Party may deem appropriate, and (b) the Indemnifying Party shall be entitled to
participate in (but not control) the defense of such action, with its counsel
and at its own expense. If the Indemnifying Party or the Indemnifying Party
thereafter seeks to question the manner in which the Indemnified Party defended
such third party claim or the amount or nature of any such settlement, the
Indemnifying Party shall have the burden to prove by a preponderance of the
evidence that the Indemnified Party did not defend or settle such third party
claim in a reasonably prudent manner.
