                  information" shall not include information which: (i) is or

                  (ii) was known by the receiving Party on a nonconfidential
                  basis prior to the disclosure thereof; or (iii) is acquired by

                  agent, servant, employee, employer, officer, director,

                  manufacture, sell or offer for sale, or enter into or
                  negotiate any agreement, understanding or arrangement to
                  develop, acquire, manufacture, sell or offer for sale, any
                  place in the world any product which is directly or indirectly
                  competitive with any Product for usage with portable or
                  handheld computers, or (ii) finance any person or entity in
                  any manner or in any way inconsistent with the intents and
                  purposes of (i) above.

                  In the event of Cybex's breach, or threatened breach, of any
                  term or provision contained in this Section 7.2, Cybex agrees
                  that Mobility and/or its affiliates shall be entitled to the
                  right of specific performance and/or both temporary and
                  permanent injunctive relief. It is the intent of each of the
                  Parties that the covenants not-to-compete contained in this
                  Section 7.2 be enforced to the fullest extent permitted by
                  applicable law. Accordingly, should a court of competent
                  jurisdiction determine that the scope of any covenant is too
                  broad to be enforced as written, it is the intent of each of
                  the Parties hereto that the court should reform such covenant
                  to such narrower scope as it may determine is necessary to
                  make such covenant enforceable. Each of the Parties hereto
                  recognizes and agrees that this Section 7.2 is necessary and
                  essential to the protection of the business conducted and to
                  be conducted in the future by the Parties and/or their
                  respective affiliates, and to enable the Parties to realize
                  and drive all of the benefits, rights and expectations of this
                  Agreement; that the area and duration of the covenants herein
                  are in all aspects, under the circumstances of this Agreement,
                  reasonable; and that good and valuable consideration exists
                  for the such Party agreeing to be bound by such covenants.

                  destruction of any completed or partially completed Products
                  which may occur prior to delivery thereof ("delivery" being
                  defined as F.O.B. point of shipment), and that Cybex shall
                  bear the loss from the destruction or breakage of any Products
                  after delivery thereof.

         13.2     This Agreement is subject to strikes and lockouts or refusal
                  of employees to work, or the inability of Mobility to be able
                  to cause Products manufactured for Mobility outside of the
                  United States of America to be delivered into the United
                  States of America, and for such cause that portion of this
                  Agreement affected thereby may be suspended during the
                  continuance thereof. Impossibility of performance by reason of
                  any legislative, executive or judicial act of any government
                  or state any other similar or dissimilar cause which cannot be
                  prevented by either Party or by the exercise of proper
                  diligence, shall excuse performance of this Agreement.
                  Bankruptcy of either Party shall allow the other Party, at its
                  sole discretion, to terminate this Agreement. The Parties
                  agree that the Party who is unable to perform its obligations
                  hereunder because of any of the reasons set forth in this
                  Section 13.2 shall give prompt written notice to the other
                  Party of such inability to perform.

                  Any Party may change its address for notice by written notice
                  given to the other Party in accordance with this Section.

         13.5     Any debts, obligations, covenants or liabilities accrued
                  hereunder between the Parties hereto shall survive the
                  expiration or termination of this Agreement for whatever
                  reason.

         13.6     This Agreement (including the Attachments hereto) constitutes
                  the entire agreement between the Parties regarding the subject
                  matter hereof and supersedes all prior agreements and

                  with respect to the subject matter hereof. Each of the Parties

                  to implement and retain the intent and spirit of this
                  Agreement, and omit to take such actions which could hinder
                  the furtherance of such intent and spirit.

         13.7     If any provision of this Agreement is held to be illegal,
                  invalid or unenforceable under present or future laws
                  effective during the term, such provision shall be

                  fully severable and this Agreement shall be construed and
                  enforced as if such illegal invalid or unenforceable provision
                  never comprised a part hereof, and the remaining provisions
                  hereof shall remain in full force and effect and shall not be
                  affected by the illegal, invalid or unenforceable provision or
                  by its severance herefrom. Furthermore, in lieu of such
                  illegal, invalid or unenforceable provision, there shall be
                  added automatically as part of this Agreement a provision as
                  similar in its terms to such illegal, invalid or unenforceable
                  provision as may be possible and be legal, valid and
                  enforceable.

         13.8     The headings in the Agreement are for convenience of reference
                  only and shall not limit or otherwise affect the meaning of

         13.9     This Agreement may be executed in one or more counterparts,
                  each of which shall be deemed an original and all of this
                  shall constitute one and the same instrument but only one of
                  which need be produced.

         EXECUTED as of the date first above written.
