of every kind and description, wherever such properties, assets, operations and
businesses may be located, as the same exist on the date of this Agreement.

                 8.2  Organization.  Prior to the Closing, the parties hereto
agree to use best efforts to insure that the Partnership shall preserve the
relationships of the Partnership Operations with lessors, suppliers,
distributors, customers and others having business relations with it; provided,
however, that nothing herein shall prevent the Partnership from asserting any
claims against any such lessors, suppliers, distributors, customers and others.

                 8.3  Compliance with Laws.  The parties hereto agree to use
best efforts to insure that the Partnership shall use all reasonable efforts to
comply duly with all laws applicable to the Partnership Operations, the
violation of which would be reasonably likely to result in a material adverse
effect upon the Partnership Operations.


                                   ARTICLE IX

                                 MISCELLANEOUS

                 9.1  Survival of Representations and Warranties.  The several
representations and warranties of the parties contained in this Agreement or in
any instrument delivered pursuant hereto shall survive the Closing Date for a
period of one year; provided however, that the representations and warranties
contained in Sections 2.2 and 3.2 shall survive the Closing Date without
limitation.

                 9.2  Fees and Expenses.  Each of the parties shall bear its
own expenses in connection with the negotiation and consummation of the
transactions contemplated by this Agreement.  If either of the parties has
retained a broker or finder in connection with the transactions contemplated
herein, such party shall bear the fees and expenses of such broker or finder.

                 9.3  Further Assurances.  From time to time, each party,
without further consideration, will execute and deliver such documents
(including, without limitations, any tax election) and take such action as the
other party may reasonably request in order to more effectively consummate the
transactions contemplated hereby and to vest in Kodiak II title to the
Partnership Interests and the MGP Shares and to vest in Riken title to the ARC
Shares.  SPX agrees to negotiate in good faith with its creditors to obtain all
necessary modifications, consents, amendments or waivers which may be required
pursuant to the agreements listed on Schedule A attached hereto that are not
being repaid or refinanced as contemplated by Section 5.5.

                 9.4  Governing Law; Jurisdiction.  This Agreement shall be
governed by and construed in accordance with the laws of New York (without
giving effect to its principles of conflict of laws).  The parties acknowledge
and agree that each has entered into this Agreement in the mutual expectation
that its terms and conditions will be governed by and interpreted in accordance
with the substantive laws of the State of New York.  Therefore, the parties
waive any right which any of them may have to challenge the efficacy of this
provision or to contend that the laws of any other jurisdiction should govern
the interpretation of this Agreement because such other jurisdiction has more
significant contacts with, or a greater interest in, the matter in dispute than
does the State of New York.  Each party agrees that any suit, action or
proceeding with respect to this Agreement, and the performance of the parties
hereunder shall only be brought in the Courts of the State of New York in the
County of New York, City of New York, or in the United States District Court
for the Southern District of New York.  Accordingly, each party submits
irrevocably to the exclusive jurisdiction of each such Court for the purpose of
any such suit, action or proceeding and waives irrevocably both any right which
it may have to bring any such suit, action or proceeding in any forum other
than a Court of the State of New York in the County of New York, City of New
York, or in the United States District Court for the Southern District of New
York, and any defense which it may have to the enforcement of this provision,
whether based on the inconvenience of the forum or otherwise.  Each party
acknowledges that service of process in any such suit, action or proceeding may
be effected in any manner then permitted, as the case may be, under the New
York Civil Practice Law and Rules or the Federal Rules of Civil Procedure of
the United States of America (or any instrument corresponding thereto).

                 9.5  Amendment.  This Agreement may not be amended, modified
or supplemented except upon the execution and delivery of a written agreement
executed by the parties hereto.

                 9.6  No Assignment.  This Agreement and all of the provisions
hereof shall be binding upon and inure to the benefit of the parties hereto and
their respective successors and permitted assigns, but, except as provided in
this Section 9.6, neither this Agreement nor any of the rights, interests or
obligations hereunder shall be assigned by any of the parties hereto without
the prior written consent of the other parties; Kodiak II may assign all or any
portion of its rights and obligations to purchase the Partnership Interests and
the MGP Shares under this Agreement to any person, corporation, business trust,
joint venture, association or company (a "Kodiak Permitted Assignee"); Riken
may assign all or any portion of its rights and obligations to purchase the ARC
Shares to a direct or indirect wholly-owned subsidiary of Riken (a "Riken
Permitted Assignee").  If such assignment shall be made by Kodiak II or Riken,
as the case may be, such Kodiak Permitted Assignee or Riken Permitted Assignee
shall be entitled to all of the rights and shall assume all of the obligations
of Kodiak II or Riken, as the case may be, with respect to such assignment but
such assignment shall not relieve Kodiak II or Riken, as the case may be,  of
its obligations hereunder.

                 9.7  Publicity.  None of  SPX, Riken, Kodiak, Kodiak II or
Seller shall make or issue, or cause to be made or issued, any announcement or
written statement concerning this Agreement or the transactions contemplated
hereby for dissemination to the general public without the prior written
consent of the other parties.  This provision shall not apply, however, to any
announcement or written statement required, in the opinion of counsel to such
party, to be made by law or the regulations of any federal or state
governmental agency or any stock exchange, except that the party required to
make such announcement shall, whenever practicable, consult with the other
parties concerning the timing and content of such announcement before such
announcement is made.

                 9.8  Waiver.  Any of the terms or conditions of this Agreement
which may be lawfully waived may be waived in writing at any time by the party
which is entitled to the benefits thereof.  Any waiver of any of the provisions
of this Agreement by any party hereto shall be binding only if set forth in an
instrument in writing signed on behalf of such party.  No failure to enforce
any provision of this Agreement shall be deemed to or shall constitute a waiver
of such provision and no waiver of any of the provisions of this Agreement
shall be deemed to or shall constitute a waiver of any other provision hereof
(whether or not similar) nor shall such waiver constitute a continuing waiver.

                 9.9  Notices.  Any notices and other communications to be
given in connection with this Agreement shall be in writing, and shall be
deemed to have been given upon the

invalid, illegal or unenforceable in any other jurisdiction.
