        On June 22, 2000, the Board of Directors established a Nominating
Committee. The Nominating Committee, currently consisting of Mr. Melrose, Mr.
Yarro and Mr. Raimondi, recommends nominees for positions on the Board of
Directors, reviews nominations recommended by stockholders in accordance with
the Bylaws and monitors the procedures set forth in the Bylaws for such
nominations.


COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

        During fiscal year 2000, the Compensation Committee consisted of Mr.
Noorda, Mr. Melrose, Ms. Kreidel and Mr. Repp. None of these persons is or has
been an officer or employee of the Company or any of its subsidiaries. In
addition, there are no Compensation Committee interlocks between MTI and other
entities involving MTI executive officers and Board members who serve as
executive officers of such entities.


ATTENDANCE AT BOARD AND COMMITTEE MEETINGS

        During the fiscal year ended April 1, 2000, the Board of Directors met
five times. In addition, the Audit Committee and Compensation Committee met one

such director served.


COMPLIANCE WITH SECTION 16(a) OF THE SECURITIES EXCHANGE ACT OF 1934

        Section 16(a) of the Securities and Exchange Act of 1934, as amended,
requires that the Company's executive officers and directors file reports of
beneficial ownership on Form 3 and changes in beneficial ownership on Forms 4
and 5 with the Securities and Exchange Commission ("SEC"). Executive officers
and directors are also required by the SEC rules to furnish the Company with
copies of all Section 16(a) reports they file. As part of a Section 16
compliance program established by the Company for its executive officers and
directors, the Company undertakes to file these reports on behalf of such
individuals. Based solely on its review of the Forms 3, 4 and 5 filed on behalf
of its executive officers and directors, as well as written representations from
certain individuals that no Forms 5 are required by such individuals, the
Company believes that, during the fiscal year ended April 3, 1999, all Section
16(a) filing requirements applicable to its executive officers and directors
were complied with pursuant to the SEC rules, except for the following late Form
4 filings: John Repp (August 1998, September 1998 and December 1998), Dan Brown
(December 1999) Al Melrose (February 2000), Gary Scott (February 2000) and Frank
Yoshino (February 2000). Ralph Yarro amended his March 2000 Form 3 to include
the grant of an option that he received under the Directors' Plan upon his
appointment to the Board of Directors. In addition, John Repp failed to timely
file his Form 5 to report a transfer of shares by gift.

(1) Based on an aggregate of 4,423,500 options granted to directors and
    employees of the Company in fiscal year 2000, including the Named Executive
    Officers.

(2) The potential realizable value is calculated based on the term of the option
    at its time of grant (ten years). It is calculated by assuming that the
    stock price appreciates at the indicated annual rate compounded annually for
    the entire term of the option and that the option is exercised and sold on
    the last day of its term for the appreciated stock price. No gain to the
    option holder is possible unless the stock price increases over the option
    term.
