any legal or governmental proceeding pursuant to subpoena or from making
such other statements may be required by applicable law.

                      (b) Based on the information contained in the
Schedule 13Ds, the Company agrees that it will not take the position that
any of the shares of Common Stock held by the Stockholders as of the date

Stockholder Releasing Parties warrant that they have not assigned any

                      (d) This release and Agreement are not, and shall not

liability or other wrongdoing whatsoever.

                      (e) The Company Releasing Parties agree, as soon as

Agreement in connection with matters pertaining to the Company.

                      (c) Amendment and Modification. This Agreement may be

telecopied; and on the next business day, if timely delivered to an air
courier guaranteeing overnight delivery.

                      (e) Severability. Whenever possible, each provision
of this Agreement shall be interpreted in such a manner as to be effective
and valid under applicable law, but if any provision of this Agreement is
held to be prohibited by or invalid under applicable law, such provision
shall fail to be in effect only to the extent of such prohibition or
invalidity, without invalidating the remainder of this Agreement or of any
such provision.

                      (f) 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 otherwise provided for or permitted herein neither this Agreement
nor any of the rights, interests or obligations hereunder shall be assigned
by any party hereto without the prior written consent of the other party.

                      (g) Governing Law. This Agreement and the legal
relations among the parties hereto shall be governed by and construed in
accordance with the laws of the State of Illinois, without regard to its
conflicts of law doctrine.

                      (h) Jurisdiction and Venue. Each of the Company and
the Stockholders hereby agree that any proceeding relating to this
Agreement shall be brought in the State of Illinois. Each of the Company
and the Stockholders hereby consents to personal jurisdiction in any such
action brought in any such Illinois court, consents to service of process
by registered mail made upon such party and such party's agent and waives
any objection to venue in any such Illinois court or to any claim that any
such Illinois court is an inconvenient forum.

                      (i) Counterparts. This Agreement may be executed
simultaneously in two or more counterparts, each of which shall be deemed
an original, but all of which together shall constitute one and the same
instrument.

                      (j) Headings. The headings of the Sections of this
Agreement are inserted for convenience only and shall not constitute a part
hereof or affect in any way the meaning or interpretation of this
Agreement.

                      (k) Entire Agreement. This Agreement sets forth the
entire agreement and understanding of the parties hereto in respect of the
subject matter contained herein, and supersedes all prior agreements,
promises, covenants, arrangements, communications, representations or
warranties, whether oral or written, relating to the subject matter hereof.

                      (l) Specific Performance. Each of the parties hereto
recognizes and acknowledges that a breach by a party of any covenants or
agreements contained in this Agreement will cause the other party to
sustain injury for which it would not have an adequate remedy at law for
money damages. Therefore each of the parties hereto agrees that in the
event of any such breach, the aggrieved party shall be entitled to the
remedy of specific performance of such covenants and agreements and
preliminary and permanent injunctive and other equitable relief in addition
to any other remedy to which it may be entitled, at law or in equity, and
the parties hereto further agree to waive any requirement for the securing
or posting of any bond in connection with the obtaining of any such
injunctive or other equitable relief.

                      (m) Third Parties. Nothing herein expressed or
implied is intended or shall be construed to confer upon or give to any
person or corporation, other than the parties hereto and their successors
or assigns, any rights or remedies under or by reason of this Agreement;
provided, however, it is specifically agreed that each of the Released
Parties of the Company and the Stockholders are deemed to be direct third
party beneficiaries of Section 14 of this Agreement and each of them shall
be entitled to the benefits of, and be permitted to enforce, the provisions
of Section 14 as if they were a party to this Agreement.

                      (n) Further Assurances. Each Stockholder shall, upon
request of the Company, execute and deliver any additional documents and
take such further actions as may reasonably be deemed by the Company to be
necessary or desirable to carry out the provisions hereof including but not
limited to documents and actions necessary or desirable to vest the power
to vote such Stockholder's shares of Common Stock as contemplated by this
Agreement.


                  IN WITNESS WHEREOF, the parties hereto have caused this
Agreement to be duly executed, all as of the day and year first above
written.
