2.   STATEMENT OF WORK
     -----------------

2.1  Objectives
     ----------

     This Agreement relates only to development activities for Prototypes to be
     manufactured in the Fabrication Process.

2.2  Development Activities (Tasks)
     ------------------------------

     The development program to be conducted by IBM and MTC under this Agreement
     will be conducted by executing the following Tasks. In the case of MTC, all
     work performed in connection with these Tasks shall be performed solely and
     exclusively by Representatives of MTC. In the case of IBM, all work
     performed in connection with these Tasks shall be performed solely and
     exclusively by Representative of IBM. The description of Tasks below
     includes work items and prime responsibility therefor. Although prime
     responsibility is assigned to one Party, the other Party will participate
     and use commercially reasonable efforts to cooperate fully in any
     particular work item as required by the relevant Task.

Task 1:   IBM shall provide MTC with models and design kits created by IBM for
          use in conjunction with the Fabrication Process, but only for the
          purposes of evaluating the technology, assessing future product
          development by MTC and developing and designing Prototypes to be
          manufactured solely by IBM if MTC elects to have such Prototypes
          manufactured. Such models and design kits are hereby licensed to MTC
          under the terms of the IBM Design Kit License attached hereto as
          Exhibit A. IBM may modify or alter the models and design kits and/or
          the Fabrication Process. IBM will promptly notify MTC of any such
          modifications or alterations to the design kits. Modifications or
          alterations to IBM's Fabrication Process may cause the corresponding
          Prototype designs to be unuseable for the manufacture of Products.

Task 2A:  MTC shall use the models and design kits provided by IBM solely to
          evaluate the technology, assess future product development by MTC and
          develop Prototype designs adapted to the Fabrication Process and
          Prototypes to be manufactured solely by IBM if MTC elects to have such
          Prototypes manufactured. MTC shall use commercially reasonable efforts
          to develop designs which take advantage of the unique attributes of
          the Fabrication Process in order to maximize performance and
          manufacturing yield and to minimize manufacturing cost.

Task 2B:  IBM shall provide MTC with up to a cumulative total of   [*]   RITs,
          [*]  per contract year, subject to the payment provisions in sections
          3.2 and attachment B. In addition, MTC, at its sole option, can
          substitute a RIT for a MPW Run, subject to availability from IBM. As
          part of the Prototype design(s) developed, MTC shall perform all

IBM/MTC CONFIDENTIAL

  Confidential materials omitted and filed separately with the Securities and
               Exchange Commission. Asterisks denote omissions.

         needed circuit design and modeling functions to produce GDS2 formatted
         data containing such circuits to be fabricated in the Fabrication
         Process. Fabrication of Prototypes having the additional and/or
         different features listed in Attachment B shall be subject to the
         additional payments listed therein. The Parties shall hold a Design
         Review in connection with each RIT. These Design Reviews will address
         electrical and physical design issues and release procedures.

         In connection with each RIT, IBM will accept from MTC's Technical
         Coordinator (as identified in Section 6.2) a GDS2 formatted data set
         produced by MTC during the term of this Agreement. IBM will perform
         additional ground rule checking and may provide consultation to MTC as
         to where optimization for the Fabrication Process may be possible.
         Should changes to any such GDS2 formatted data be required to correct
         ground rule errors or to optimize the Fabrication Process (pattern
         density, for example), MTC will make these changes and resubmit the
         GDS2 formatted data set. Under no circumstances will IBM make any
         (intentional) changes to any GDS2 formatted data set submitted by MTC.

         Should MTC request IBM to fabricate a Mask Set corresponding to any of
         the GDS2 formatted data sets, IBM will forward all corresponding,
         required data and supporting documentation to an internal or third
         party, where a Mask Set, will be created. Should changes to any GDS2
         formatted data set submitted by MTC be required to conform to Mask
         fabrication rules, MTC will make these changes and resubmit the GDS2
         formatted data set. Under no circumstances will IBM make any
         (intentional) changes to any GDS2 formatted data set submitted by MTC.

         Upon completion of the fabrication of each Mask Set for Prototype
         design(s) by or on behalf of IBM, IBM will schedule [*] Wafer Starts.
         IBM will use commercially reasonable efforts to complete their
         manufacture. Upon request by MTC for each RIT (and not for any MPW
         Run), just prior to the passivation and metallization steps associated
         with each such set of [*] Wafer Starts, IBM will hold up to [*] Wafers
         and complete the processing of the rest. At the request of MTC, IBM
         will then (a) scrap the held Wafers; or (b) process the held Wafers in
         the same manner as those previously processed; or (c) MTC will submit
         new GDS2 formatted data set for the wiring layers, IBM will create or
         have created a corresponding Mask Set (subject to the payments
         discussed immediately hereafter), and IBM will then process the held
         Wafers using this Mask Set. In step (c), if MTC so requests, IBM will
         modify wiring masks (not transistor masks) in any Mask Set, subject to
         a payment for the modified masks plus a one-time engineering payment
         for the corresponding RIT as referenced in Attachment B.

          Upon Wafer run completion, IBM shall initially test certain test
          structures on processed Wafers and shall thereafter deliver Prototypes
          to MTC in Wafer form or diced if requested by MTC in addition to a
          copy of data from the test structures which IBM, in

          its sole discretion, deems appropriate to disclose to MTC. MTC shall
          perform all Prototype test and characterization measurements specific
          to MTC's unique circuit designs.

Task 3:   IBM and MTC shall each provide a Technical Coordinator to coordinate
          development activities under this Agreement. The responsibilities of
          these Technical Coordinators are listed in Section 6.1 and their
          identities are given in Section 6.2.

Task 4:   MTC and IBM will meet to assess MTC's technology requirements relative
          to the Fabrication Process for the purpose of discussing future plans
          and providing inputs to the technology development plan. The further
          purpose of these meetings is to provide feedback on the technology and
          to exchange technical ideas for the development of the technology. Any
          MTC Confidential Information received under this Task 4 (i) may be
          used by IBM in the Fabrication Process; including future versions
          thereof, for any purpose, (ii) may be disclosed by IBM to licensees of
          the Fabrication Process, including future versions thereof and (iii)
          shall include the unrestricted, royalty-free right of IBM to grant
          licenses thereunder to licensees of the Fabrication Process, including
          future versions thereof.

2.3    Uncertainty of Results
       ----------------------

       Although IBM and MTC will use reasonable efforts in performing the
       development activities under this Agreement, each Party acknowledges that
       the results of the work to be performed hereunder are uncertain and
       cannot be guaranteed by either Party. The Parties also acknowledge that
       any key milestones and other checkpoint dates made in connection with
       such work are target dates only and failure to achieve any such target
       dates shall not constitute a breach of this Agreement.

2.4    Shipment and Use of Prototypes
       ------------------------------

2.4.1  IBM shall ship all items to be delivered to MTC under this Agreement FOB
       plant of manufacture.

2.4.2  MTC agrees to use all Wafers delivered by IBM to MTC under this Agreement
       for internal testing, evaluation and demonstration purposes only. MTC may
       deliver Prototypes derived from such Wafers to MTC's customers at MTC's
       discretion for testing, evaluation and demonstration purposes only,
       provided that: (i) MTC notifies such customers in writing that the
       Prototypes are preliminary versions of a Product and are intended for
       internal testing, evaluation and demonstration purposes only.

8.2    Invention Rights
       ----------------

8.2.1  Representatives of IBM or MTC performing Tasks under this Agreement who
       make an Invention, whether solely or jointly with others, agree to make
       and shall promptly make a complete written disclosure to their employer
       for patent review of such Invention, in the normal course, specifically
       pointing out those features or concepts believed to be new or different.

       Each Party agrees to promptly submit to the other Party copies, marked as
       IBM Confidential Information or MTC Confidential Information, as the case
       may be, of any written disclosures pertaining to Joint Inventions
       submitted exclusively to it, which submissions shall be subject to the
       provisions of Section 8.3 of this Agreement. Also, MTC shall promptly
       submit to IBM copies of all written disclosures submitted exclusively to
       MTC relating to the Fabrication Process.

8.2.2  Each Invention, other than a Joint Invention, shall be the property of
       the Party whose Representatives made the Invention.

8.2.3  Joint Inventions shall be jointly owned, title to all patents issued
       thereon shall be joint, all expenses incurred in obtaining and
       maintaining such patents, except as provided hereinafter, shall be shared
       equally and each Party shall have the unrestricted right to license third
       parties thereunder without accounting to the other Party. In the event
       that one Party elects not to see patent protection for any Joint
       Invention in any particular country or not to share equally in the
       expense thereof with the other Party, the other Party shall have the
       right to seek or maintain such protection at its own expense in such
       country and shall have full control over the prosecution and maintenance
       thereof even though title to any patent issuing therefrom shall be joint.

8.2.4  Each Party shall give the other Party all reasonable assistance in
       obtaining patent protection and in preparing and prosecuting any patent
       application filed by the other Party, and shall cause to be executed
       assignments and all other instruments and documents as the other Party
       may consider necessary or appropriate to carry out the intent of this
       Section 8.2.

8.2.5     All MTC Inventions relating to the Fabrication Process shall be owned
       by MTC, subject to a worldwide, irrevocable, perpetual, nonexclusive,
       nontransferable, fully paid-up and royalty-free license which MTC hereby
       grants to IBM under all such Inventions. This license includes the
       right of IBM to make, have made, use, have used, lease, import, offer to
       sell, sell and/or otherwise transfer, any apparatus, and to practice and
       have practiced any method. This license further includes the right of IBM
       to sublicense third parties to do any or all of the foregoing. MTC agrees
       that for a period of five (5) years from the Effective Date of this
       Agreement, MTC shall treat such MTC Inventions relating to the
       Fabrication process as

       other intellectual property right of the other Party,

8.3    Confidential Information:
       -------------------------

       8.3.1 For a period of seven (7) years from the date of disclosure of
       Confidential Information, the Receiving Party agrees to use the same
       degree of care and discretion to keep the Disclosing Party's Confidential
       Information confidential as it uses with its own similar information that
       it wishes to keep confidential. The Confidential Information received by
       a Receiving Party shall not be used for any purpose other than in
       connection with exercising the rights and licenses granted to it under
       this Agreement, subject to the obligation of confidentiality and subject
       to the terms and conditions of the licenses granted herein. Each Party
       agrees to inform its Representatives of the confidential nature of the
       other Party's Confidential Information, and each of such Representatives
       shall agree in writing to act in accordance with the terms and provisions
       of this Article 6. Each Receiving Party shall be responsible for any
       breach of this Agreement by any of its Representatives.

       8.3.1.1 Either Receiving Party may use the "Residuals" of the Disclosing
       Party's Confidential Information for any purpose, royalty-free, subject
       to the obligation of confidentiality. "Residuals" means the ideas,
       concepts, know-how and techniques, related to the Receiving Party's
       business activities, which are contained in the Disclosing Party's
       Confidential Information and retained in the unaided memories of the
       Receiving Party's employees who have had rightful access to the
       Disclosing Party's Confidential Information pursuant to this Agreement.

       8.3.2 The Receiving Party may disclose the Confidential Information of
       the Disclosing Party only to: the Receiving Party's Representatives on a
       need-to-know basis, subject to the requirements of Section 8.3.

       8.3.3 Notwithstanding any other provisions of this Agreement, the
       nondisclosure and use obligations specified herein shall not apply to any
       Confidential Information which:

       8.3.3.1 is already lawfully in the possession of the Receiving Party
       prior to being furnished the Receiving Party by the Disclosing Party,
       provided that the source of such information was not and does not become
       known, prior to disclosure, by the Receiving Party to be prohibited from
       disclosing the information to the Receiving Party by legal, contract or
       fiduciary obligation to the Disclosing Party;

IBM/MTC CONFIDENTIAL

Page 15
<PAGE>

     8.3.3.2 is independently developed by employees (without use of
     Confidential Information) of the Receiving Party or any of its
     Subsidiaries;

     8.3.3.2 becomes generally publicly available without breach of this
     Agreement;

     8.3.3.3 is rightfully received by the Receiving Party on a nonconfidential
     basis from a third party that is not known by the Receiving Party to be
     prohibited from disclosing the information to the Receiving Party by legal,
     contract or fiduciary obligation to the Disclosing Party;

     8.3.3.4 is released for disclosure by the Disclosing Party with its written
     consent; or

     8.3.3.6 is inherently and appropriately disclosed in the use, lease,
     marketing, sale, or other distribution of Prototypes, or Products, as the
     case may be and publicly available supporting documentation therefor by or
     for the Receiving Party or any of its Affiliates.

     8.3.4 Disclosure of Confidential Information shall not be precluded if such
     disclosure is:

     8.3.4.1 in response to a valid order of a court or other governmental body;
     provided, however, that the Receiving Party shall first promptly provide
     the Disclosing Party prompt notice of the order and provide the Disclosing
     Party the opportunity to make a commercially reasonable effort to obtain a
     protective order or other appropriate remedy; provided that if such
     protective order is not obtained, or if the Disclosing Party waives
     compliance with the provisions of this Section 8.3.4.1 in writing, the
     Receiving Party will furnish only that part of the Confidential Information
     that the Receiving Party is legally required to be so disclosed and the
     Receiving Party shall exercise its best commercially reasonable efforts to
     obtain reasonable assurance that confidential treatment will be accorded to
     the Confidential Information so disclosed; or

     8.3.4.2 otherwise required by law (prior to such disclosure, however, the
     Receiving Party will provide written notification to the Disclosing Party,
     signed by an executive of the Receiving Party, stating that the Receiving
     Party believes in good faith that the disclosure is required by law); or

     8.3.4.3 necessary to establish the Receiving Party's rights under this
     Agreement.

     8.3.4.5 If any Confidential Information falls under an exception set forth
     in Sections 8.3.4.1 through 8.3.4.6 the Receiving Party shall not disclose
     that the Disclosing Party hereto was the source of that Confidential
     Information.

     8.3.4.6 All Confidential Information not reasonably necessary or useful for
     the Receiving Party to exercise the rights and licenses granted in this
     Agreement shall be returned to the Disclosing Party or destroyed by the
     Receiving Party upon termination of this Agreement. Any
