        THIS DOCUMENT OF UNDERSTANDING by and between Diodes Inc (hereafter
DIODES), and Microsemi Corporation (hereafter MSC), shall have an Effective Date
of July 6, 2001.

        WHEREAS, the parties desire to utilize their unique expertise and
capabilities for their mutual benefit by establishing a Cooperative Business
Arrangement (the "CBA") between their respective organizations in order to
provide the most effective management and technical approach for cooperatively
achieving new and improved processes, product designs and product performance
for selected products; and

        WHEREAS, the parties met in Watertown, Massachusetts on April 26, 2001
(the "MEETING"), and identified certain Action Items, which they believed needed
to be resolved to their mutual satisfaction, and where appropriate, incorporated
into formal Agreements.

        WHEREAS, it is contemplated at this time that the CBA will be
coordinated and performed in various design, engineering and manufacturing sites
respectively owned or controlled by the parties in both the United States and in
foreign geographies; and

        WHEREAS, MSC owns and controls a proprietary automated manufacturing
facility in its Watertown facility, where it makes a family of products sold
under its POWERMITE(R)3 trademark.

        WHEREAS, DIODES desires to obtain a non-exclusive license under certain
MSC intellectual property rights for the manufacture of products utilizing the
novel POWERMITE(R)3 package design containing silicon rectifier die, and to
market such products under the POWERMITE(R)3 trademark.

        WHEREAS, the parties desire to cooperatively establish marketing

establishing a competitive additional source of such POWERMITE(R)3 products; for
maintaining the quality of such POWERMITE(R)3 products; for cost effectively
serving the market requirements in the geographies of consumption; and for
cooperatively establishing POWERMITE(R)3 product improvements that dynamically
respond to market demands

        NOW THEREFORE, the parties desire at this time to summarize the mutual
understandings they have made at the Meeting, and more particularly specify the
Action Items required to complete the documentation for the CBA, such mutual
agreements and Action Items are as follows:

1.      The parties agree to negotiate in good faith for nontransferable,
        nonexclusive, worldwide, irrevocable, royalty bearing licenses to make
        (but not have made) and to use, to lease and to sell, or to otherwise
        dispose of products that are made pursuant to any and all intellectual
        property rights ("IPR") owned or controlled by MSC, that comprehend the
        manufacturing of products sold by MSC under its POWERMITE(R)3 trademark.
        An exemplary IPR License Agreement is attached hereto as EXHIBIT A, and
        by this reference is made a part hereof.



        The royalty rates under such license shall be as follows:

               1. Year 1 - [CONFIDENTIAL] of Net Revenues.
               2. Year 2 - [CONFIDENTIAL] of Net Revenues.
               3. Year 3 - [CONFIDENTIAL] of Net Revenues.
               4. Thereafter - [CONFIDENTIAL] of Net Revenues.

        The parties agree that Year 1 for the initial calculation of royalties,
        shall commence on the first month following the day that DIODES receives
        a bone fide qualification by one of its customers of the first Licensed
        Product produced in its Shanghai facility, utilizing the IPR licensed
        hereunder, or, the first Licensed Product made, used or otherwise
        disposed of by DIODES under the MSC trademark POWERMITE(R)3.

        In the event MSC hereafter grants to any third party licenses
        substantially the same in scope and duration as the licenses granted to
        DIODES regarding POWERMITE(R)3, as contemplated herein, MSC warrants
        that the royalty rates under such third party licenses shall be
        substantially the same as, or greater than, the royalty rates specified
        in the licenses granted to DIODES, taking into reasonable evaluation the
        mutual considerations under which such DIODES licenses were granted,
        vis-a-vis, the mutual considerations under which such third party
        licenses were granted.

        In the event DIODES agrees to transfer to MSC any of its IPR for the
        manufacture, use and/or sale of products covered by any DIODES IPR, the
        parties agree to negotiate in good faith for a non-exclusive, worldwide,
        irrevocable, royalty bearing license under such DIODES IPR, which
        license shall be substantially similar to the terms and conditions set
        forth in the IPR License Agreement between the parties regarding
        POWERMITE(R)3

        Notwithstanding anything to the contrary herein stated, or in any other
        agreement between the parties, sales made by one party to the other
        party of products that are covered by such one parties IPR shall not be
        subject to the payment of royalties, and shall be deemed excluded from
        the definition of Net Revenues.

2.      The parties also agree to negotiate in good faith for a limited license
        which grants to DIODES the right to market and sell POWERMITE(R)3
        packaged products under MSC's POWERMITE(R)3 trademark. ("TML"). An
        exemplary TML Agreement is attached hereto as EXHIBIT B, and by this
        reference is made a part hereof.

3.      From the Effective Date hereof until December 31, 2003, or such other
        date as the parties may hereafter agree upon, DIODES agrees to buy from
        MSC its requirements of POWERMITE(R)3 packaged products, and MSC, to the
        extent it has the available capacity, agrees to sell to DIODES.
        POWERMITE(R)3 packaged products. During such period, the parties agree
        to negotiate in good faith the terms and conditions of a Technology
        Transfer and Technical Training Agreement ("TTA") whereby the
        manufacturing technology reasonably required to manufacture
        POWERMITE(R)3 packaged products will be strategically and effectively
        transferred to DIODES. An exemplary TTA is attached hereto as EXHIBIT C,
        and by this reference is made a part hereof.

4.      It is contemplated at this time that the licensed automated
        POWERMITE(R)3 manufacturing line will be located by DIODES in its
        Shanghai facility. Accordingly, Microsemi shall provide the required
        technical support within the purview of the TTA, at DIODES expense.

        MSA. An exemplary MSA is attached hereto as EXHIBIT D, and by this
        reference is made a part hereof.

        DIODES Shanghai facility, or in any other licensed facility as may
        hereafter be installed, MSC shall have the option right to purchase up

        manufacture of such wafers, and that such sales may be best defined

        and conditions of a mutually acceptable Purchase Agreement.
