would apply to all such Losses.

(e) The indemnification provided in this Section 8.2,

Agreement or any other such agreement or instrument to the contrary.

8.3. Bulk Sales Compliance.

To the extent applicable, Buyer hereby waives compliance by
Seller with the provisions of the bulk sales law of any U.S. jurisdiction, and
in any event, Seller covenants and agrees to pay and discharge when due all
claims of any governmental entities and creditors of Seller and its subsidiaries
that could be asserted against Buyer by reason of such non-compliance. Seller
agrees to indemnify and hold Buyer harmless from and against and shall on demand
reimburse Buyer for any and all Losses suffered by Buyer by reason of Seller's
failure to pay and discharge any such claims.

8.4. Additional Instruments.

At any time and from time to time after the Closing, at either
party's request and without further consideration, Seller or Buyer, as the case
may be, shall execute and deliver such other instruments of sale, transfer,
conveyance, assignment and confirmation and take such other action as Seller or
Buyer may reasonably deem necessary or desirable in order to more effectively
transfer, convey, and assign to Buyer, and confirm Buyer's title to and interest
in and responsibility and liability for, the Assets and Contracts and the
consummation of the transactions contemplated herein. Without limiting the
generality of the foregoing, Seller will cooperate with and assist Buyer in
renewing, or transferring, into Buyer's name those Permits for which Buyer
requests such assistance and cooperation at the appropriate time for such
renewal or transfer as determined by Buyer.

8.5. Access to Books, Records and Employees.

From and after the Closing Date, Buyer will authorize and
permit Seller and its respective representatives to have access during normal
business hours, upon reasonable notice and for reasonable purposes and in such
manner as will not unreasonably interfere with the conduct of Buyer's business,
to Books and Records within the control of Buyer that relate to the

Facility. From and after the Closing Date, Seller will authorize and permit
Buyer and its representatives to have access during normal business hours, upon
reasonable notice and for reasonable purposes and in such manner as will not
unreasonably interfere with the conduct of Seller's business, to all books and
records, files, documents and other correspondence related to the Facility prior
to the Effective Time, which are not included among the Books and Records. Buyer
and Seller agree to maintain all books, records, files, documents and other
correspondence related to the Facility prior to the Effective Time in accordance
with their respective normal document retention practices after the Closing
Date.

This Agreement and the documents referred to herein and to be
delivered pursuant hereto constitute the entire agreement between the parties
pertaining to the subject matter hereof, and supersede all prior and
contemporaneous agreements, understandings, negotiations and discussions of the
parties, whether oral or written, and there are no warranties, representations
or other agreements between the parties in connection with the subject matter
hereof, except as specifically set forth herein or therein. No amendment,
supplement, modification, waiver or termination of this Agreement shall be
binding unless executed in writing by the party to be bound thereby. No waiver
of any of the provisions of this Agreement shall be deemed or shall constitute a
waiver of any other provision of this Agreement, whether or not similar, nor
shall such waiver constitute a continuing waiver unless otherwise expressly
provided. The representations and warranties of each party hereto shall be
deemed to be material and to have been relied upon by the other party. The
representations, warranties, covenants and agreements of Seller and Buyer
contained herein shall survive the execution and delivery of this Agreement and
consummation of the transactions contemplated hereby and, as to the
representations and warranties, shall be effective until the relevant time
limitation for making any indemnity claim with respect to such representations
and warranties under Sections 8.1 and 8.2. shall have been reached and no
longer.

10.2. Expenses.

Except as otherwise specifically provided herein, each of the

Obligations Law shall apply to this Agreement. Each of the parties hereto, in
respect of itself and its properties, agrees to be subject to (and hereby
irrevocably submits to) the nonexclusive jurisdiction of the United States
federal court for the Southern District of New York or New York state court

proceeding arising out of or relating to this Agreement or the transactions
contemplated herein, and irrevocably agrees that all claims in respect of any
such suit, action or proceeding may be heard and determined in any such court.
Each of the parties hereto irrevocably waives, to the fullest extent it may
effectively do so under applicable

Law, any objection to the laying of the venue of any such suit, action or
proceeding brought in any such court and any claim that any such suit, action or
proceeding brought in any such court has been brought in an inconvenient forum.
Either party hereto may make service on the other party by sending or delivering
a copy of the process to the party to be served at the address and in the manner
provided for the giving of notices in Section 10.5 hereof. Nothing in this
