                                       OF

         CLASS A CUMULATIVE, REDEEMABLE AND EXCHANGEABLE PREFERRED STOCK

                         PURSUANT TO THE SECTION 401(c)

            OF THE GENERAL CORPORATION LAW OF THE STATE OF CALIFORNIA


         Douglas J. Tullio and Jeffrey J. Dunnigan certify that:

         FIRST: They are the president and secretary, respectively, of ALPHA
MICROSYSTEMS, a California corporation (the "Company").

         SECOND: The number of outstanding shares of the Company's Class A
Cumulative, Redeemable and Exchangeable Preferred Stock (the "Class A Preferred
Stock") and Class B Cumulative, Redeemable and Exchangeable Preferred Stock (the
"Class B Preferred Stock") is zero (0) shares.

         THIRD: That the Board of Directors of the Company, pursuant to the
authority so vested in the Articles of Incorporation of the Company and in
accordance with Section 401(c) of the General Corporation Law of the State of
California, duly adopted the following resolutions reducing the number of
authorized shares of the Class A Preferred Stock and Class B Preferred Stock to
zero (0) shares (the "Reduction") since the Reduction solely reduces the number
of shares constituting series of the Company's capital stock that were
designated by the Board of Directors pursuant to the Certificate of
Determination of Rights and Preferences of Class A Cumulative, Redeemable and
Exchangeable Preferred Stock, Class B Cumulative, Redeemable and Exchangeable
Preferred Stock, Class C Cumulative, Redeemable and Exchangeable Preferred Stock
and Voting Preferred Stock of Alpha Microsystems filed on August 25, 1998 (the

            other acts and things as may be necessary or appropriate and
            consistent with carrying out the intent and purposes of this and the
            foregoing resolutions and recitals, the execution and delivery of
            the foregoing documents or the doing of any act or thing being
            conclusive evidence as to the appropriateness thereof and of the
            authority of the party executing or doing the same to so execute and
            deliver any such documents and to do any such act and thing."
