ITEM 5.   OTHER EVENTS.

     A.   MERGER AGREEMENT.

          On August 9, 1999, Zitel Corporation entered into an Agreement and
Plan of Merger and Reorganization whereby a newly formed wholly owned
subsidiary of Zitel is to be merged into MatriDigm Corporation with the
result that all of the issued and outstanding capital stock of MatriDigm will
be converted into fully paid and nonassessable Common Stock of Zitel and
Zitel will be the owner of all of the issued and outstanding capital stock of
MatriDigm. The transaction is subject to regulatory approvals and certain
other conditions and is expected to close in approximately 60 days from
August 9, 1999. Zitel expects to issue approximately 2,300,000 shares of its
authorized but unissued capital stock at the closing of the transaction.
Zitel currently owns approximately 31 percent of the stock of MatriDigm on a
fully converted basis and is represented on the Board of Directors of
MatriDigm by three of its executive officers, Jack H. King, Henry C. Harris
and Anna M. McCann. The consideration to be paid by Zitel was determined in
arm's length negotiations with MatriDigm and certain of its principal
stockholders.

     Reference is made to the Exhibit filed with this report for the actual
terms of the Merger Agreement.
