relieve the assigning party of its obligations hereunder if such assignee does
not perform such obligations.

     SECTION 4.03. Governing Law; Venue. Except to the extent that Delaware Law
                   --------------------
is mandatorily applicable to the rights and obligations of parties to this
Agreement, this Agreement shall be governed by, and construed in accordance with
the laws of the Commonwealth of Massachusetts applicable to contracts executed
in and to be performed in that Commonwealth. Subject to the provisions of
Section 4.05 below, all actions and proceedings arising out of or relating to
this Agreement shall be heard and determined exclusively in any Massachusetts
state or federal court sitting in the City of Boston.

     SECTION 4.04. Waiver of Jury Trial. Each of Parent and the Company, and
                   --------------------
each Note Payee and Management Payee hereby irrevocably waives all right to
trial by jury in any action, proceeding or counterclaim (whether based on
contract, tort or otherwise) arising out of or relating to this Agreement or the
actions of Parent, the Company or any Note Payee or Management Payee in the
negotiation, administration, performance and enforcement thereof.

     Section 4.05. Dispute Resolution. Except to the extent otherwise
                   ------------------
specifically provided below in this Section 4.05, all claims, controversies,
differences or disputes between or among any of the parties hereto arising from
or relating to this Agreement and the transactions contemplated hereby shall be
determined solely and exclusively by arbitration in accordance with the rules of
commercial arbitration then in effect of the American Arbitration Association,
or any successors thereto ("AAA"), in Boston, Massachusetts, unless the parties
                            ---
otherwise agree in writing. Each of the parties consents to venue for such
arbitrations in Boston, Massachusetts and to service of process by certified or
registered mail. Upon commencement of any arbitration pursuant hereto, the
parties shall jointly select an arbitrator. In the event the parties fail to
agree upon an arbitrator within twenty (20) days, then each party shall select
an arbitrator and such arbitrators shall then select a third arbitrator to serve
as the sole arbitrator; provided that if either party, in such event, fails to
                        -------------
select an arbitrator within seven (7) days, such arbitrator shall be selected by
the AAA upon application of either party. Judgment upon the award of the agreed
upon arbitrator or the so chosen third arbitrator, as the case may be, shall be
binding and shall be entered by a court of competent jurisdiction. The parties
agree to abide by any decision rendered in any such arbitration as final and
binding and waive the right to submit the dispute to a public tribunal for a
jury or non-jury trial. The fees and expenses of the AAA in any such arbitration
shall be shared equally by the parties, unless otherwise ordered by the
arbitrator(s). Each party shall be responsible for all costs incurred by it in
preparing for and participating in the arbitration, unless the arbitrator(s)
order that a party shall be entitled to recover its actual out-of-pocket costs
and expenses, including without limitation reasonable attorneys' fees incurred
in connection with such arbitration. Notwithstanding

                                       -8-

anything to the contrary in this Section 4.05, in no event, however, shall this
Section 4.05 be deemed to preclude a party hereto from instituting legal action
seeking relief in the nature of a restraining order, an injunction, a specific
performance order or the like in order to protect his or its rights pending the
outcome of an arbitration hereunder.

     SECTION 4.06. Headings. The descriptive headings contained in this
                   --------
Agreement are included for convenience of reference only and shall not affect in
any way the meaning or interpretation of this Agreement.

     SECTION 4.07. Counterparts. This Agreement may be executed and delivered
                   ------------
(including by facsimile transmission) in one or more counterparts, and by the
different parties hereto in separate counterparts, each of which when executed
and delivered shall be deemed to be an original but all of which taken together
shall constitute one and the same agreement.
