If the subject report could not be filed without unreasonable effort or expense
and the registrant seeks relief pursuant to Rule 12b-25(b), the following
should be completed.  (Check box if appropriate)

         [X]        (a)     The reasons described in reasonable detail in Part
                            III of this form could not be eliminated without
                            unreasonable effort or expense;

         [X]        (b)     The subject annual report, semi-annual report,
                            transition report on Form 10-K, Form 20-F, Form
                            11-K, Form N-SAR, or portion thereof, will be filed

                            the prescribed due date; or the subject quarterly
                            report or transition report on Form 10-Q, or portion
                            thereof will be filed on or before the fifth
                            calendar day following the prescribed due date; and

                    (c)     The accountant's statement or other exhibit required
                            by Rule 12b-25(c) has been attached if applicable.

                             PART III--NARRATIVE

State below in reasonable detail the reasons why Forms 10-K and Form 10-KSB,
20F, 11-K, 10-Q, and 10-QSB, N-SAR or the transition report portion thereof
could not be filed within the prescribed time period.

        The Annual Report on Form 10-K for the year ended December 31, 2001 (the
        "Annual Report") could not be filed within the prescribed time period
        because MAI Systems Corporation (the "Company") is unable, without
        unreasonable effort or expense to finalize its books and records and
        thereby ensure that it presented accurately and completely the
        information required by the rules and regulations of the Securities and
        Exchange Commission as they apply to Form 10-K. The Company was unable
        to finalize the Annual Report because the Company is reclassifying its
        historical financial statements for recently discontinued operations of
        certain divisions by implementing the recently issued Statement No. 144
        issued by The Financial Accounting Standards Board. The Company requires
        additional time to ensure that we fully understand the requirements of
        FAS 144 and its implications to our recently discontinued operations.
        Additionally, the Company has recently reduced its work force in its
        finance and related departments and this has limited our ability to deal
        in a timely fashion with the incremental SEC reporting demands
        associated with our year end reporting and the preparation of Form 10-K.

                                                              SEC 1344 (11/91)

     ----------------------------------   --------------   ---------------------

(2)  Have all other periodic reports required under Section 13 or 15(d) of the
     Securities Exchange Act of 1934 or Section 30 of the Investment Company Act
     of 1940 during the preceding 12 months (or for such shorter) period that
     the registrant was required to file such reports) been filed? If answer is
     no, identify report(s).
                                                                [X] Yes   [ ] No


(3)  Is it anticipated that any significant change in results of operations from
     the corresponding period for the last fiscal year will be reflected by the
     earnings statements to be included in the subject report or portion
                                                                [ ] Yes   [X] No

     If so, attach an explanation of the anticipated change, both narratively
     and quantitatively, and, if appropriate, state the reasons why a
     reasonable estimate of the results cannot be made.
