               Paragraph 3(h)       [Retirement]

                                   ----

          (b)  Willingham agrees to disclose promptly to the Company and does
     assign and agree to assign to the Company, free from any obligation to
     Willingham, all Willingham's right, title and interest in and to any and
     all ideas, concepts, processes, improvements and inventions made,
     conceived, written, acquired, disclosed or developed by Willingham, solely
     or in concert with others, during the term of Willingham's employment by
     the Company, which relate to the business, activities or facilities of the
     Company, or resulting from or suggested by any work Willingham may do for
     the Company or at its request. Willingham further agrees to deliver to the
     Company any and all drawings, notes, photographs, copies, outlines,
     specifications, memoranda and data relating to such ideas, concepts,
     processes, improvements and inventions, to cooperate fully during
     Willingham's employment and thereafter in the securing of copyright,
     trademark or patent protection or other similar rights in the United States
     and foreign countries, and to give evidence and testimony and to execute
     and deliver to the Company all documents requested by it in connection
     therewith.

          (c)  Except as expressly set forth below, Willingham agrees, whether
     during Willingham's employment pursuant to this Agreement or thereafter,
     except as authorized or directed by the Company in writing or pursuant to
     the normal exercise of Willingham's responsibilities hereunder, not to
     disclose to others, use for Willingham's benefit, copy or make notes of any
     confidential knowledge or trade secrets or any other knowledge or

                                       6
<PAGE>

     information of or relating to the business, activities or facilities of the
     Company or any of its affiliates which may come to Willingham's knowledge
     during Willingham's employment pursuant to this Agreement or thereafter.
     Willingham will not be bound to this obligation of confidentiality and
     nondisclosure if:

               (i)    the knowledge or information will become part of the
          public domain by publication or otherwise through no fault of
          Willingham;

               (ii)   the knowledge or information is disclosed to the recipient
          by a third party and Willingham reasonably believes such third party
          is in lawful possession of the knowledge or information and has the
          lawful right to make disclosure thereof; or

               (iii)  Willingham is required to disclose such information
          pursuant to applicable law or by a court of competent jurisdiction.

     photographs, models and equipment of any nature which are in Willingham's
     possession or control and which are the property of the Company.

          (e)  The parties understand and agree that the remedies at law for
     breach of the covenants in this Paragraph 7 would be inadequate and that
     the Company will be entitled to injunctive or such other equitable relief
     as a court may deem appropriate for any breach of these covenants. If any
     of these covenants will at any time be adjudged invalid to any extent by
     any court of competent jurisdiction, such covenant will be deemed modified
     to the extent necessary to render it enforceable.

          20.  Binding Arbitration.
               -------------------

          (a)  Generally.  The arbitration procedures described in this
               ---------
     Paragraph 20 will be the sole and exclusive method of resolving and
     remedying claims under this Agreement ("Disputes"); provided that nothing
                                             ---------   --------
     in this Paragraph 20 will prohibit a Person from instituting litigation to
     enforce any Final Arbitration Award. Except as otherwise provided in the
     Commercial Arbitration Rules of the American Arbitration Association as in
     effect from time to time (the "AAA Rules"), the arbitration procedures
                                    ---------
     described in this Paragraph 20 and any Final Arbitration Award will be
     governed by, and will be enforceable pursuant to, the Uniform Arbitration
     Act as in effect in the Commonwealth of Massachusetts from time to time.
     "Person" for the purposes of this Agreement means an individual, a
      ------
     partnership, a limited liability company, a corporation, an association, a
     joint stock company, a trust, a joint venture, an unincorporated
     organization or any governmental entity.

           (b) Notice of Arbitration.  If a Person asserts that there exists a
               ---------------------
     Dispute, then such Person (the "Disputing Person") will give each other
                                     ----------------
     Person involved in such Dispute a written notice setting forth the nature
     of the asserted Dispute.  If all such Persons do not resolve any such
     asserted Dispute prior to the 10th business day after such notice is given,
     then any of them may commence arbitration pursuant to this Paragraph 20 by
     giving each other Person involved in such Dispute a written notice to that
     effect (an "Arbitration Notice"), setting forth any matters which are
                 ------------------
     required to be set forth therein in accordance with the AAA Rules.

                                      10
<PAGE>

          (c)   Selection of Arbitrator. The Persons involved in any Dispute
                -----------------------
     will attempt to select a single arbitrator by mutual agreement. If no such
     arbitrator is selected prior to the 10th business day after the related
     Arbitration Notice is given, then an arbitrator which is experienced in
     matters of the type which are the subject matter of the Dispute will be
     selected in accordance with the AAA Rules.

          (d)   Conduct of Arbitration.  The arbitration will be conducted in
                ----------------------
     Boston, Massachusetts under the AAA Rules, as modified by any written
     agreement among the Persons`involved in the Dispute in question.  The
     arbitrator will conduct the arbitration in a manner so that the final
     result, determination, finding, judgment or award determined by the
     arbitrator (the "Final Arbitration Award") is made or rendered as soon as
                      -----------------------
     practicable, and the Persons involved will use reasonable efforts to cause
     a Final Arbitration Award to occur within 90 days after the arbitrator is
     selected.  Any Final Arbitration Award will be final and binding upon all
     Persons and there will be no appeal from or reexamination of any Final
     Arbitration Award, except in the case of fraud, perjury or evident
     partiality or misconduct by the arbitrator prejudicing the rights of such
     Persons or to correct manifest clerical errors.

          (e)  Enforcement.  A Final Arbitration Award may be enforced in any
               -----------
     state or federal court having jurisdiction over the subject matter of the
     related Dispute.

           (f) Expenses.  Each prevailing Person in any arbitration proceeding
               --------
     described in this Paragraph 20 will be entitled to recover from any non-
     prevailing Person(s) its reasonable attorneys' fees and disbursements and
     other out-of-pocket costs in addition to any damages or other remedies
     awarded to such prevailing Person, and the non-prevailing Person(s) also
     will be required to pay all other costs and expenses associated with the
     arbitration; provided that (i) if an arbitrator is unable to determine that
                  --------
     one or more Persons are prevailing Person(s) in any such arbitration
     proceeding, then such costs and expenses will be equitably allocated by
     such arbitrator upon the basis of the outcome of such arbitration
     proceeding, and (ii) if such arbitrator is unable to allocate such costs
     and expenses in such a manner, then the costs and expenses of such
     arbitration will be paid one-half by the Company, and the LLC, on the one
     hand, and one-half by Willingham, on the other hand, and each Person
     involved in such arbitration will pay the out-of-pocket expenses incurred
     by it.  As part of any Final Arbitration Award, the arbitrator may
     designate the prevailing Person(s) for purposes of this Paragraph 20.

     certain portion of the Interests will be subject to repurchase by the
     Company at cost. If the undersigned ceases to be employed by the Employer
     (except for certain circumstances) prior to January 1, 2000, then all of
     the Interests will be subject to repurchase by the Company at cost; if such
     cessation of the undersigned's employment occurs prior to January 1, 2004,
     then not less than 25% of the Interests will be subject to repurchase by
     the Company at cost.

5.        The fair market value on the date hereof of the property with respect
     to which the election is being made, determined without regard to any lapse
     restrictions: $.3856 per Interest.
