6.1  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

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.

     6.1.1 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.

     6.3.1 is already lawfully in the possession of the Receiving Party prior to
     being furnished to the Receiving Party by the Disclosing Party, provided
     that the source of such information was not and does not become known by
     the Receiving Party, 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;

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

     6.3.2 becomes generally publicly available without breach of this
     Agreement;

     6.4.3 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

     contract or fiduciary obligation to the Disclosing Party;

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

     Products, or IBM Licensed Products, as the case may be and publicly
     available supporting documentation therefor by or for the Receiving Party
     or any of its Affiliates.

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

     6.4.1 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 6.4.1 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 assurances that confidential treatment will be accorded
     to the Confidential Information so disclosed; or

     6.4.2 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

     6.4.3 necessary to establish the Receiving Party's rights under this

Sections 6.4.1 through 6.4.6 the Receiving Party shall not disclose that the
Disclosing Party hereto was the source of that Confidential Information.

6.6  All Confidential Information not reasonably necessary or useful for the
Receiving Party, but only 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 oral Confidential

this Agreement.

7.1  Employees of IBM or MTC performing services under this Agreement who make
an Invention, whether solely or jointly with others, shall 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 confidentiality provisions of Article 6 of
this Agreement.

7.2  Each Invention, other than a Joint Invention, shall be the property of the
Party whose employees made the Invention (hereinafter "Owning Party") subject to
a license which the Owning Party hereby grants to the other Party under such
Invention and any patent protection obtained therefor. Upon request, the Owning
Party shall advise the other Party of those countries, if any, wherein it
intends to seek patent protection at its expense. The other Party may propose
countries for filing in addition to those selected by the Owning Party. The
Owning Party shall promptly notify the other Party, as to each proposed country,
whether patent protection will be sought. For any proposed country wherein
patent protection is not to be sought by the Owning Party, the other Party may
elect to seek patent protection, at its own expense, but the Owning Party shall
have title to any resulting patent, subject to the grant of a license to the
other Party pursuant to the terms set forth in Section 7.6.

7.3  With respect to each Invention, other than a Joint Invention, the Owning
Party upon request shall provide such other Party with a copy of the first
English-language patent application so filed, the filing particulars of any
corresponding foreign patent application, and, as may be requested by the other
Party, copies of any such corresponding foreign patent applications and all
official papers relating thereto. The Owning Party may also publish such
Invention subject to the options granted to the other Party in Section 7.2.

7.4  Joint Inventions shall be jointly owned, title to all patents issued
thereon shall be joint, all expense incurred in obtaining and maintaining such
patents, except as provided hereinafter, shall be jointly shared and each Party

JOINT DEVELOPMENT AGREEMENT

right to license third parties thereunder without accounting. In the event that
one Party elects not to seek 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 jointly owned.

7.5  Each Party shall give the other Party all commercially 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 reasonably necessary or appropriate to carry out the intent of this
Section 7.5.

7.6  All licenses granted under Section 7.2 shall be worldwide, irrevocable,
nonexclusive, nontransferable and royalty-free (except as set forth in Section 4
hereof); shall include the right to make, have made, use, have used, lease,
sell, and/or otherwise transfer any apparatus, and to practice and have
practiced any method. All such licenses shall include the right of the grantee
to grant revocable or irrevocable sublicenses to its Affiliates, such
sublicenses to include the right of the sublicensed Affiliates to
correspondingly sublicense their own Affiliates. The term of any license granted
under Section 7.2 shall extend for the full term of the licensed patent.

     7.6.1 Upon the termination or expiration of this Agreement, all such
     licenses shall further include the right of grantee to grant revocable or
     irrevocable sublicenses to third Parties only under the Joint Technology
     but not under any patents or patent applications based thereon provided,
     however, that if this Agreement is terminated by either Party pursuant to
     the provisions of Section 8.5 hereof, the non-terminating party's right to

3.0   Design Review Deliverables
This section describes the Design Review process and deliverables. A Design
Review shall mean a meeting of the parties to review the design work to date to
determine compliance to all agreed-to specification parameters. The location of
the Design Reviews will alternate between IBM and MTC facilities. The Design
Review process may be modified based on the complexity of the design with the
mutual agreement of the IBM and MTC Technical Coordinators.

3.1   Preliminary Design Review (PDR)(Interim Design Review)
The goal of the Preliminary Design Review (PDR) is to review the design work to
date to determine that the design effort is on track and that no major issues
exist with the design simulation or design methodology, predicted performance,
chip layout (floor plan), or product assembly and test. This review should
address predicted performance of the circuit.

Preliminary Design Reviews will include as applicable:
i.    Review final specifications
ii.   Schematic diagrams
iii.  Simulation results for key parameters
iv.   Thermal analysis
v.    Compliance Matrix: Simulated Performance vs.. Specification
vi.   Preliminary chip layout (floor plan)
vii.  Test approach
viii. Design Review documentation package
ix.   Risk analysis and mitigation plan

3.2   Detailed Design Review (DDR) (Final Design Review)
The goal of the Detailed Design Review (DDR) is to comprehensively review all
aspects of the design and layout to assure compliance to specifications and
manufacturability prior to tape out. The design must be Design Rule Checking
(DRC) and Layout vs. Schematic (LVS) verified and free of errors at this point.
Details of the final simulations, accounting for all relevant layout parasitics,
should be covered extensively. Predicted performance, yield, and parameter
sensitivity analysis should be reviewed. Final plots of the top level, major
blocks or sections and critical signals or paths should be reviewed. Final
assembly drawings of the packaged and/or assembled product are to be reviewed.
Test methodologies and test plans for engineering characterization should also
be reviewed.

Detailed Design Reviews will include as applicable:
