trading days. Shares sold subject to this Section 1.1 must be executed during

right of first refusal to purchase any Stock from any other Participant (as
defined in Section 3.1 herein) pursuant to the same terms and conditions of such
private sale, but such right of first refusal shall not apply to any private

party, subject to the terms of such offer. In the event that multiple
Participants desire to sell shares of Stock, then the offer to purchase shall be
allocated equally among the selling Participants. This provision shall not

         4 .6. GOVERNING LAW; SEVERABILITY. This Agreement will be governed by

Agreement to be governed by or construed or enforced in accordance with the laws
of any other jurisdiction. Whenever possible, each provision of this Agreement

applicable law, but if any provision of this Agreement is held to be prohibited
by or invalid under applicable law, such provision shall (a) be reformed by the
Parties to reflect the intent of the Parties, or (b) if reformation is not
possible, be ineffective only to the extent of such prohibition or invalidity,

such disagreements and controversies shall be subject to binding arbitration as
arbitrated in accordance wit the then current Commercial Arbitration Rules of
the American Arbitration Association in Chicago, Illinois before one neutral
arbitrator. Either Party may apply to the arbitrator seeking injunctive relief
until the arbitration award is rendered or the controversy is otherwise
resolved. Without waiving any remedy under this Agreement, either Party may also
seek from any court having jurisdiction any interim or provisional relief that
is necessary to protect the rights or property of that Party, pending the
establishment of the arbitral tribunal (or pending the arbitral tribunal's
determination of the merits of the controversy). In the event of any such
disagreement or controversy, neither Party shall directly or indirectly reveal,
report, publish or disclose any information relating to such disagreement or
controversy to any person, firm or corporation not expressly authorized by the
other Party to receive such information or use such information or assist any
other person in doing so, except to comply with actual legal obligations of such
Party or unless such disclosure is directly related to an arbitration proceeding
as provided herein, including, but not limited to, the prosecution or defense of
any claim in such arbitration. The costs and expenses of the arbitration
(excluding attorneys' fees) shall be paid by the non-prevailing Party or as
determined by the arbitrator. This paragraph shall survive the termination of
this Agreement.


         4.8 ENTIRE AGREEMENT. This Agreement sets forth the entire
understanding of the Parties with respect to the subject matter hereof,
supersedes all existing agreements between them concerning such subject matter
and supersedes any and all prior negotiations, correspondence and
understandings. This Agreement is the result of negotiation and accordingly, the
normal rules of construction to the effect that any ambiguity shall be resolved
against the drafting party shall not be employed in the interpretation of this
Agreement.
