         2.       Warranties

                  2.1.     MEI warrants that it is the sole owner of the
                           Patents, that MEI has not previously granted any
                           assignment or exclusive license in or to the Patents
                           to any third party, and that MEI has the full right
                           and capacity to assign the Patents to MCMS, and to
                           enter into and carry out its obligations under this
                           Agreement, without conflicting with any other
                           obligation of MEI.

         3.       Assignment and Grant Back License

                  3.1.     MEI agrees to assign, and hereby does assign, to
                           MCMS, MEI's entire right, title and interest in and
                           to the Patents, including without limitation, damages
                           and payments for past or future infringements
                           thereof, if any, and the right to bring suit and
                           recover against any third party for acts of
                           infringement occurring before the date of this
                           Agreement, if any. MEI agrees to execute,
                           concurrently herewith, a formal assignment document
                           (the "Assignment") for the Patents in the form
                           attached hereto. In the event of any conflict between
                           the provisions of this Agreement and the Assignment,
                           the provisions of this Agreement shall take
                           precedence.

                  3.2.     Within thirty (30) days after the date of this
                           Agreement, MEI will deliver to MCMS all documentation
                           in MEI's possession or control relating to the
                           Patents. MEI may, at its discretion, retain a copy of
                           any documentation provided to MCMS pursuant to this
                           subparagraph.

                  3.3.     MCMS hereby grants MEI and MEI's Affiliates, an
                           irrevocable (except as set forth in Section 3.6),
                           non-transferable, fully paid up, worldwide,
                           non-exclusive license to practice all inventions
                           covered by the Patents, and to make and have made,
                           use, offer for sale, sell, and lease products, which,
                           without the license granted hereunder, would
                           constitute an infringement of the Patents. MEI shall
                           have no right to sublicense the Patents to any third
                           party without the prior written consent of MCMS,
                           which consent shall not

Patent and Invention Disclosure                                           Page 2
Assignment and License Agreement
   3
                           be unreasonably withheld, provided, however, that
                           MCMS's failure to consent to MEI's grant of a
                           sublicense to an MCMS competitor shall not be deemed
                           to be unreasonable.

                  3.4.     MEI and MEI's Affiliates shall not assign or transfer
                           any of its rights granted hereunder without the prior
                           written consent of MCMS. Notwithstanding the
                           foregoing, an assignment or transfer of the Agreement
                           and the licenses granted therein may be effected by
                           operation of law, such as for example, by merger,
                           consolidation, sale of the business or assets,
                           reincorporation, or nonbankruptcy reorganization.

                  3.5.     Neither MCMS nor MEI shall be required to disclose or
                           to license to the other any inventions and
                           improvements relating to the Patents which are first
                           conceived after the Effective Date.

                  3.6.     This Agreement shall commence on the Effective Date
                           and shall continue thereafter in perpetuity;
                           provided, however, that either party may, upon ninety
                           (90) days written notice to the other party,
                           terminate this Agreement in the event of a material
                           breach thereof by such party; provided, further, that
                           if such breach is cured within such ninety (90) day
                           period, this Agreement shall not be so terminated.

         4.       Miscellaneous

                  4.1.     Except as set forth in the Recapitalization
                           Agreement, both MEI and MCMS neither warrant nor
                           represent that the use of the Patents will not result
                           in infringement of any patents of any third party.

                  4.2.     MEI shall indemnify and hold MCMS and its Affiliates
                           and their respective officers, directors, employees,
                           agents, shareholders, principals, successors and
                           assigns harmless from and against any claims,
                           judgments, damages, costs (including attorneys' fees)
                           and expenses arising out of MEI's and MEI's
                           Affiliates' practice of the Patents under this
                           Agreement, including without limitation any claim
                           alleging infringement or misappropriation of third
                           party intellectual property rights.

                  4.3.     MEI shall, at MCMS' expense, cooperate with and
                           assist MCMS in the provision of documents and
                           information in connection with the Patents as
                           reasonably necessary to effectuate the procurement
                           and maintenance of the Patents. MCMS shall have the
                           exclusive right, but shall not be obligated, to take
                           appropriate legal action against any third party that
                           to its knowledge infringes the Patents.

                  4.4.     No modification of or amendment to this Agreement
                           shall be valid unless in a writing signed by the
                           parties hereto referring specifically to this

                 condition to be waived, and no such waiver shall be deemed to
                 constitute the waiver of any other breach of the same or of any
                 other term or condition of this Agreement.
