     normal exercise of Stolpe's responsibilities hereunder, not to disclose to
     others, use for Stolpe's benefit, copy or make notes of any confidential
     knowledge or trade secrets or any other knowledge or information of or
     relating to the business, activities or facilities of the Company or any of
     its affiliates which may come to Stolpe's knowledge during Stolpe's
     employment pursuant to this Agreement or thereafter. Stolpe 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 Stolpe;

               (ii)      the knowledge or information is disclosed to the

     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

     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

     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 Stolpe, 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

     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
