                       9.  LAWS GOVERNING; ARBITRATION.
                           ---------------------------

     The construction, interpretation and enforcement of this Agreement and the
rights of the parties hereunder shall be governed by the internal laws of the
Commonwealth of Pennsylvania without regard to any jurisdiction's conflicts or
choice of law provisions.

     Any controversy or claim arising out of or relating to this Agreement, or
the breach thereof, shall be settled by arbitration in Pittsburgh, Pennsylvania,
in accordance with the Rules of the American Arbitration Association for
Commercial Arbitration, and the decision in such arbitration shall be final and
conclusive on the parties and judgment upon such decision may be entered in any
court having jurisdiction thereof.  Seller and Buyer agree that such location is
the most convenient forum for both parties.  Buyer and Seller will share equally
the total expense of such arbitration; but each party shall bear its own legal,
accounting and other similar fees and expenses.

     The parties retain the right to seek and obtain interim relief from a court
of competent jurisdiction pending receipt of an award in accordance with this
Section 9, or temporary restraining orders or other emergency, temporary or
preliminary equitable relief to preserve the status quo by enjoining or
restraining a party hereto pending final and binding arbitration hereunder and
the parties hereto acknowledge and agree to the right to seek such relief.

                              10.  MISCELLANEOUS.
                                   -------------

    10.1  Counterparts; Telecopy.
          ----------------------

          This Agreement may be executed in one or more counterparts, each of
which shall be deemed an original, but all of which when taken together shall
constitute one and the same instrument.  Delivery of executed signature pages
hereof by facsimile transmission shall constitute effective and binding
execution and delivery hereof.

    10.2  Assignment.
          ----------

          This Agreement may not be assigned by either party hereto without the
prior written consent of the other party.

    10.3  Entire Agreement.
          ----------------

          This Agreement and the documents referenced herein contain the entire
agreement between the parties and wholly cancel, terminate and supersede any and
all previous or contemporaneous oral agreements, negotiations, commitments and
writings between the parties hereto with respect to such subject matter.  No
change, modification, termination, notice of termination, discharge or
abandonment of this Agreement or any of the provisions hereof or thereof, nor
any representation, promise or condition relating to this Agreement, shall be
binding upon the parties hereto unless made in writing and signed by the parties
hereto, except that termination or notices of termination which may be effected
pursuant to the terms of this

                                      -9-
<PAGE>
 
Agreement by either party to this Agreement, shall be binding if made in writing
and signed by the applicable party.

    10.4  Interpretation.
          --------------

          Articles, titles and headings to sections herein are inserted for
convenience of reference only and are not intended to be a part of or to affect
the meaning or interpretation of any of the provisions of this Agreement.  All
references to sections, subsections or schedules contained in this Agreement are
references to the sections and subsections of this Agreement.  All references to
the word "including" shall have the meaning represented by the phrase "including
without limitation."

    10.5  Expenses.
          --------

          Except as otherwise expressly provided herein, Seller and Buyer each
will pay all costs and expenses, including any and all legal and accounting
fees, of its performance and compliance with all agreements and conditions
contained herein on its part to be performed or complied with.

    10.6  No Presumption Against the Draftsman.
          ------------------------------------

          There shall be no presumption against any party on the ground that
such party was responsible for preparing this Agreement or any part hereof.

    10.7  Public Announcements.
          --------------------

          Neither Buyer nor Seller shall, without the approval of the other
party (which may not be unreasonably withheld), make any press release or other
public announcement concerning the transactions contemplated by this Agreement,
except as and to the extent that such party shall be so obligated by law
(including any legal obligation imposed on Seller in connection with its status
as a publicly-held corporation), in which case the other party shall be advised
and Buyer and Seller shall use their reasonable efforts to cause a mutually
agreeable release or announcement to be issued.

    10.8  Waivers.
          -------

          Any term or provision of this Agreement may be waived, or the time for
its performance may be extended, by the party or parties entitled to the benefit
thereof, but any such waiver must be in writing and must comply with the notice
provisions contained in Section 8.  The failure of any party hereto to enforce
at any time any provision of this Agreement shall not be construed to be a
waiver of such provision, nor in any way to affect the validity of this
Agreement or any part hereof or the right of any party thereafter to enforce
each and every such provision.  No waiver of any breach of this Agreement shall
be held to constitute a waiver of any other or subsequent breach.

    10.9  Partial Invalidity.
          ------------------

          Wherever possible, each provision hereof shall be interpreted in such
a manner as to be effective and valid under applicable law, but in case any one
or more of the provisions contained herein shall, for any reason, be held to be
invalid, illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provisions of this Agreement, and
this Agreement shall be construed as if such invalid, illegal or unenforceable
provisions had never been contained herein unless the deletion of such provision
or provisions would result in such a material change as to cause the completion
of the transactions contemplated hereby to be unreasonable.

   10.10  Incorporation by Reference.
          --------------------------

          Any and all schedules referred to herein or attached hereto are
incorporated herein by reference thereto as though fully set forth at the point
referred to in this Agreement.
