1.       BASIS OF PRESENTATION

         Companies for which this report is filed are MAI Systems Corporation
         and its wholly-owned subsidiaries (the "Company"). The information
         contained herein is unaudited, but gives effect to all adjustments
         (which are normal recurring accruals) necessary, in the opinion of
         Company management, to present fairly the condensed consolidated
         financial statements for the interim period. All significant
         intercompany transactions and accounts have been eliminated in
         consolidation.

2.       INVENTORIES

         Inventories are summarized as follows:

3.       PLAN OF REORGANIZATION

         In 1993, the Company emerged from a voluntary proceeding under the
         bankruptcy protection laws. Notwithstanding the confirmation and
         effectiveness of its Plan of Reorganization (the "Plan"), the
         Bankruptcy Court continues to have jurisdiction to resolve disputed
         pre-petition claims against the Company to resolve matters related to
         the assumptions, assignment or rejection of executory contracts
         pursuant to the Plan and to resolve other matters that may arise in
         connection with the implementation of the Plan.

         Shares of Common Stock are currently being distributed by the Company
         to its former creditors. As of August 14, 1997, 6,755,751 shares of
         Common Stock had been issued pursuant to the Plan and were outstanding.
         The Company estimates that approximately 6,820,338 shares will be
         issued to creditors.

4.       BUSINESS ACQUISITIONS

         CIMPRO:

         On March 6, 1997, the Company acquired substantially all the assets and
         assumed certain liabilities of CIMPRO, which develops and markets
         process manufacturing software, for $5,900,000 in cash. To finance the
         acquisition of CIMPRO, the Company sold 400,000 shares of its Common
         Stock in a private placement for $6.50 per share and issued $6,000,000
         of 11% subordinated notes payable due in 2004 to an investment fund
         managed by Canyon Capital Management LP ("Canyon"). Interest on the
         subordinated notes is payable semi-annually commencing September 3,
         1997.

         Associated with the stock issuance, the Company incurred $300,000 of
         issuance costs which are included in additional paid-in capital in the
         accompanying condensed consolidated balance sheet as of June 30, 1997.

         The acquisition of CIMPRO has been accounted for using the purchase
         method of accounting. A preliminary allocation of the purchase price is
         as follows:

                                                                -------
                                                                $ 5,900
                                                                =======
</TABLE>

         Intangible assets are being amortized on a straight-line basis over the
         expected periods to be benefited of five to seven years.

         GAMING SYSTEMS INTERNATIONAL:

         In March 1997, the Company acquired options to purchase 3.5% of Gaming
         Systems International ("GSI") Common Stock from two individuals in
         exchange for 14,930 shares of the Company's Common Stock valued at
         $104,500 and notes payable of $104,500. The transaction resulted in an
         increase in goodwill of $209,000.

5.       STOCK WARRANTS

         Warrants to purchase 750,000 shares of the Company's Common Stock at $8
         per share were issued in connection with the issuance of the 11%
         subordinated debt. These warrants are exercisable and callable (by the
         Company) under certain circumstances at any time within seven years and
         the 11% subordinated notes may be used to exercise the warrants. The
         Company recorded an original issue discount of $1,027,000 which
         represents the fair value of the warrants at the time of issuance. The
         fair value of the warrants was recorded in connection with the issuance
         of the warrants and is reflected as a reduction in the face value of
         the subordinated notes.

6.       INCOME (LOSS) PER SHARE

         In February 1997, the Financial Accounting Standards Board issued
         Statement of Financial Accounting Standards ("SFAS") No. 128, "Earnings
         Per Share". SFAS No. 128 specifies new standards designed to improve
         the earnings per share ("EPS") information provided in financial
         statements by simplifying the existing computational guidelines,
         revising the disclosure requirements and increasing the comparability
         of EPS data on an international basis. Some of the changes made to
         simplify the EPS computations include: (a) eliminating the presentation
         of primary EPS and replacing it with basic EPS, with the principal
         difference being that the common stock equivalents are not considered
         in computing basic EPS, (b) eliminating the modified treasury stock
         method and the three percent materiality provision and (c) revising the
         contingent share provisions and the supplemental EPS data requirements.
         SFAS No. 128 also makes a number of changes to existing disclosure
         requirements. SFAS No. 128 is effective for financial statements issued
         for periods ending after December 15, 1997, including interim periods.
         Accordingly, the financial statements for the Company's fourth quarter
         ending December 31, 1997, will include a restatement of historical
         income (loss) per share to conform to the requirements of SFAS No. 128.
         The effects of this change are not expected to have a material effect
         on income (loss) per common share.

         Primary and fully diluted income (loss) per share for 1996 and 1997,
         are computed using 6,867,752 and 9,187,400 shares of Common Stock,
         respectively for the three months ended June 30, and 7,356,250 and
         8,891,404 shares of Common Stock, respectively for the six months ended
         June 30. These share amounts represent shares of Common Stock (adjusted
         for stock split in August 1995) expected to be issued in accordance
         with the Plan of Reorganization and the weighted average number of
         shares and equivalent shares of common stock outstanding during the
         period. Common stock equivalents consist of dilutive outstanding stock
         options and warrants and are calculated using the treasury stock
         method. Common Stock equivalents are not included in the 1997,
         calculation as they would be anti-dilutive.

7.       SUBSEQUENT EVENT

         In July 1997, the Company received a preliminary arbitration decision
         regarding the purchase price of assets and assumed liabilities acquired
         from Hotel Information Systems, Inc. in August 1996. The preliminary
         decision requires a reduction to the purchase price of approximately
         $931,000. The final purchase price reduction amount rendered by the
         arbitrator will reduce recorded goodwill.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
         RESULTS OF OPERATIONS

LIQUIDITY AND CAPITAL RESOURCES

At June 30, 1997, working capital increased by $1,529,000 from a deficit of
$8,270,000 at December 31, 1996, to a deficit of $6,741,000. Excluding unearned
revenue (which will not give rise to cash disbursements) of $19,545,000, the
Company's working capital is $12,804,000 or a ratio of current assets to current
liabilities of 1.74 to 1.0. The comparable ratio at December 31, 1996, was 1.15
to 1.0. The Company's working capital position has improved due to the issuance
of common stock, and greater sales of software, networking, and computer
equipment offsetting an increase in operating expenses due to acquisition and
product development.

Cash and cash equivalents were $2,913,000 at June 30, 1997, as compared to
$3,857,000 at December 31, 1996. The Company continues to have a $4,000,000
secured revolving credit facility. The availability of this line of credit is
based on a calculation reflecting the age and nature of certain accounts
receivable. At June 30, 1997, approximately $2,114,000 was drawn down under this
facility.

Net cash used for investing activities in the six months ended June 30, 1997,
totaled $6,845,000. Capital expenditures comprised $743,000, while the
acquisition of CIMPRO and the acquisition of options to purchase 3.5% of GSI
accounted for $6,102,000.

Net cash provided by financing activities included $6,000,000 from the issuance
of 11% subordinated notes payable due in 2004 in connection with the CIMPRO
acquisition. The Company's working capital was increased by the issuance of
400,000 shares of $0.01 par value common stock ("Common Stock") totaling
$2,300,000, net of issuance costs of $300,000, and the increased utilization of
the revolving credit facility of $2,114,000.

Stockholders' equity changed to $1,624,000 at June 30, 1997, from $2,058,000 at
December 31, 1996, principally due to the issuance of Common Stock totaling
$2,300,000, net of issuance costs, and the net loss for the six-months ended
June 30, 1997, of $3,336,000.

The Company believes it will continue to have sufficient cash available to fund
its operating and capital requirements through 1997.

Revenues for the three months ended June 30, 1996, were $15,034,000 compared to
$18,413,000 (a 22.5% increase) for the comparable period of 1997. The $3,379,000
increase is net of an anticipated decline in the Company's legacy revenues of
$2,074,000 or 26%. Non-legacy revenues increased by $5,453,000 or 77%.


                                       8
<PAGE>   9
Gross profit for the three months ended June 30, 1996, was $6,288,000 compared
to $6,187,000 for the comparable period of 1997. The decrease in the gross
profit percentage from 41.8% in the three months ended June 30, 1996, to 33.6%
for the comparable period for 1997, reflects decreased profit margins for both
the legacy business and for the Company's sales of lower-margin third-party
products.

Selling, general and administrative expenses ("SG&A") increased from $3,715,000
for the three months ended June 30, 1996, to $6,156,000 for the comparable
period of 1997. The increase is principally attributable to increased marketing
efforts and a larger salesforce, which resulted in increased software, networks,
and professional services revenues in the three months ended June 30, 1997,
compared to the comparable period of 1996.

Research and development costs were $302,000 for the three months ended June 30,
1996, compared to $1,479,000 for the comparable period of 1997. The increase is
attributable to the capitalization of certain software development costs which
qualify for capitalization as product enhancement costs in the three months
ended June 30, 1996, whereas all development costs were expensed in the
comparable period in 1997, and an increased level of development activity in
both the Company's hospitality and manufacturing products.

Other operating income for the three months ended June 30, 1996, related to a
settlement (net of expenses) of a claim relating to the disposition of certain
subsidiaries in 1993. In the three months ended June 30, 1997, other operating
income was principally from foreign exchange gains and collections made on
non-U.S. accounts receivable previously written off.

The amortization of intangibles of $508,000 for the three months ended June 30,
1997 was due to the acquisitions of HIS, CIMPRO, and the minority ownership of
Gaming Systems International. There was no comparable amortization expense
during the second quarter of 1996.

</TABLE>

Revenues for the six months ended June 30, 1996, were $29,765,000 compared to
$35,237,000 for the comparable period of 1997. The increase in revenues of
$5,472,000 is net of an anticipated decline in legacy revenues of $5,158,000 or
31.9%. Non-legacy revenues increased by $10,630,000 or 78.3%.

Gross profit for the six months ended June 30, 1996, was $11,375,000 compared to
$12,230,000 for the comparable period for 1997. The decrease in the gross profit
percentage from 38.2% in the six months ended June 30, 1996, to 34.7% for the
comparable period for 1997, reflects decreased profit margins from the Company's
sales of lower-margin third-party products and from legacy revenues. For
strategic reasons, legacy services were outsourced to Olivetti North America and
Olivetti Canada, Ltd., in December 1996.

Selling, general and administrative expenses increased from $6,478,000 or 21.8%
of revenues in the six months ended June 30, 1996, to $11,702,000 or 33.2% of
revenues in the comparable period of 1997. The increase is attributable to
increased marketing efforts and a larger salesforce, which resulted in increased
software, networks, and professional services revenues in the six months ended
June 30, 1997, compared to the comparable period of 1996. In addition, SG&A
increased due to residual integration costs associated with the August 1996
acquisition of Hotel Information Systems and the integration costs associated
with the March 1997 acquisition of CIMPRO. Higher facilities costs in connection
with the combination of Irvine, California operations into a single building
(which will lower future costs) and higher telecommunications costs, due to
increased traffic from HIS and CIMPRO, also contributed to increased SG&A
expenses.

Research and development costs increased from $989,000 or 3.3% of revenues for
the six months ended June 30, 1996, to $2,685,000 or 7.6% of revenues for the
comparable period in 1997, due to a significantly larger set of product
development and sustaining engineering activities. The acquisitions of the HIS &
CIMPRO product lines, together with obtaining exclusive world-wide rights to the
Lodging Touch International software product, have resulted in increased expense
in the development and sustaining of these products.

Other operating income for the six months ended June 30, 1996, was from the
settlement (net of expenses) of a claim relating to the disposition of certain
subsidiaries in 1993. In the six months ended June 30, 1997, other operating
income was principally from foreign exchange gains and collections made on
non-U.S. receivables previously written off.

The amortization of intangibles of $824,000 for the six months ended June 30,
1997 is related to the acquisitions of HIS, CIMPRO, and the minority ownership
of Gaming Systems International. There was no comparable amortization expense
during the first two quarters of 1996.

PART II - OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

         As a consequence of the commencement of the Company's bankruptcy
         proceedings, the Company has filed objections to a large number of
         proofs of claim. Sums determined to be due to claimants, as a result of
         settlement or judicial determinations, will be treated under the Plan
         of Reorganization as claims and claimants will receive either cash or
         shares of common stock in exchange for their claims. The Company does
         not believe the outcome of these objections to be material.

         Further, the Company instituted several adversary proceedings prior to
         the effective date of the Plan of Reorganization. None of those
         proceedings involve allegations of material claims against the Company.
