Encore Computer Corporation
Notes to Condensed Consolidated Financial Statements

A.       Nature of Operations and Summary of Significant Accounting Policies

Nature of Operations
The condensed consolidated financial statements include the accounts of Encore
Computer Corporation and subsidiaries ("Encore" or the "Company"). All material
intercompany balances and transactions have been eliminated in consolidation.

The accompanying condensed consolidated financial statements are unaudited and
have been prepared by Encore in accordance with generally accepted accounting
principles. Certain information and footnote disclosures normally included in
the Company's annual consolidated financial statements have been condensed or
omitted. These condensed consolidated financial statements should be read in
conjunction with the audited consolidated financial statements for the year
ended December 31, 1998.

The condensed consolidated financial statements, in the opinion of the Company,
reflect all adjustments (including normal recurring accruals) necessary for a
fair statement of the results for interim periods. All adjustments made during
the interim periods are normal recurring adjustments. The year end condensed
statement of net assets in liquidation data is derived from audited financial
statements but does not include all disclosures required by generally accepted
accounting principles.

Intention of Liquidation
During fiscal 1997, Encore Computer Corporation sold substantially all of its
assets to Sun Microsystems, Inc. ("Sun"). Furthermore, during fiscal 1998, the
Company sold its real-time computer systems business to Gores Technology Group
("Gores"). After these transactions, management contemplated that the Company
would be liquidated. However, because of a provision of the agreements relating
to Encore's sale of its storage products business to Sun, Encore's stockholders
could not vote on the liquidation of Encore at the meeting on September 11,
1998, at which they approved the sale of the real-time computer systems
business.

The Board of Directors terminated the employment of the Company's President on
September 30, 1998 and the employment of the Company's Chief Executive Officer
on November 24, 1998 in view of the fact that the Company no longer had any
active business. The Company's staff was reduced to its General Counsel (who
took the position of President), its Chief Financial Officer, its Vice President
of Human Resources (who continued to be involved in employee compensation
matters arising out of the sales of the storage products and the real-time
computer systems businesses) and a few clerical and administrative employees.
The Company also moved its offices to a substantially smaller space, which it
occupied under a short-term lease. Those offices were closed June 30, 1999 and
all employees were terminated. Certain Gould Electronics Inc. executives were
elected to serve without pay as President and Treasurer of the Company, and the
Company's further activities are conducted in space provided by Gould in
Eastlake, Ohio. Management expects that liquidation of the Company will occur.
As a result, the Company has adopted the liquidation basis of accounting as of
December 31, 1998 and for all periods subsequent to December 31, 1998.

Under the liquidation basis of accounting, assets are stated at their estimated
net realizable value and liabilities are stated at their estimated amounts.

                                     Page 7

<PAGE>

The valuation of assets and liabilities necessarily requires many estimates and
assumptions, and there are substantial uncertainties in liquidating the Company.
The valuations presented in the accompanying Statement of Net Assets in
Liquidation represent estimates based on present facts and circumstances, the
estimated realizable values of assets, and estimated liabilities and estimated
costs associated with carrying out the liquidation of the Company. The actual
values and costs could be higher or lower than the amounts recorded as of
September 26, 1999.

The assets of the Company available for distribution to shareholders on
liquidation of Encore would be (i) the Company's assets, less its liabilities,
at September 26, 1999, plus or minus (ii) any sum by which the amount received
from Gores is less than the full amount of the receivable reflected on the
Company's September 26, 1999 balance sheet, plus or minus (iii) any amount by
which severance and other costs related to the sale of the Company's businesses
are less or greater than the accruals for them on the September 26, 1999 balance
sheet, plus or minus (iv) any amount by which the costs of liquidation and costs
related to contingent liabilities, including pending litigation, are less or
greater than the reserves reflected on the September 26, 1999 balance sheet,
minus (v) expenses incurred after September 26, 1999 which have not been
contemplated in the accruals. The amount, if any, of the assets available for
distribution to common shareholders upon liquidation of Encore may depend on
whether Encore repurchases the convertible preferred stock held by Gould or such
preferred stock is otherwise eliminated. Subsequent to September 26, 1999, Gould
converted such preferred stock into 13,295,815 shares of common stock.

B.       Asset Purchase Agreement with Sun Microsystems

On November 24, 1997, the Company sold substantially all the assets associated
with its storage products business to Sun Microsystems, Inc. ("Sun"). The Asset
Purchase Agreement under which the transaction took place contemplated that Sun
would pay $185 million for the storage products business, of which $150 million
would be paid in cash at the closing and $35 million would be paid on July 1,
1998, subject to Sun's right to make offsets against the second payment. In
fact, because of certain closing adjustments, Sun paid Encore $151,168,227 at
the closing.

Shortly before July 1, 1998, Sun asserted claims against Encore totaling
$9,692,000. Because of that, on July 1, 1998, Sun paid only $25,308,000 of the
$35,000,000 which was due on that date. After negotiations regarding these
issues, Sun and Encore entered a Settlement Agreement and Mutual Release
pursuant to which Sun paid the Company an additional $2,500,000 on July 16, 1999
and released these claims.

On November 24, 1997, Gould held (i) notes, secured by all of Encore's assets,
under which Encore owed Gould $93.55 million for money Encore had borrowed from
Gould plus unpaid interest, and (ii) convertible preferred stock of Encore with
a liquidation preference totaling $411 million, which Encore had issued to Gould
between 1991 and 1996 in exchange for cancellation of indebtedness for money
Encore had borrowed from Gould and interest on those borrowings. In addition,
Gould held approximately 48.44% of Encore's common stock, which Gould had
obtained as part of the consideration for the sale of its Computer Systems
Division to Encore in 1989 or through conversion of convertible preferred stock.
In connection with the sale of Encore's storage products business to Sun, Encore
and Gould agreed that Encore would redeem all the convertible preferred stock
which Gould held for $60 million, of which $25 million was to be paid at the
closing of the Sun transaction, and the balance was to be satisfied with the
second payment due from Sun. In addition, Gould agreed that if it received the
entire $35 million by July 31, 1998, Gould would waive its right to receive
additional shares of preferred stock with a liquidation preference of
approximately $43 million which were due to it as past due dividends on the
convertible preferred stock which was being redeemed. Finally, Gould agreed that
if Encore were liquidated before November 24, 1999, Gould would waive any right
it had as a holder of Encore's common stock with regard to the first $30 million
of liquidating distributions made to Encore's common stockholders.

                                     Page 8

<PAGE>

In connection with the sale of Encore's storage products business to Sun, Gould
also entered into an agreement with Sun under which Gould guaranteed most of
Encore's obligations under the Asset Purchase Agreement between Encore and Sun,
agreed to provide whatever funds were necessary to ensure that Encore would not
become insolvent within one year after the closing of the transaction with Sun,
and indemnified Sun against any losses Sun might incur if the sale of Encore's
storage products business to Sun was challenged in an insolvency proceeding
relating to Encore commenced within two years after the closing.

Restricted cash was held in an escrow account pursuant to an escrow agreement
dated November 24, 1997 between the Company and Sun. The escrow agreement was
established to ensure that certain of the Company's liabilities at the closing
date of the Sun transaction, would be paid when due. As the Company paid these
liabilities, escrow funds were released to the Company. By June 27, 1999, all
the restricted funds had been released by Sun to the Company.

Because Sun withheld $9,692,000 of the payment due on July 1, 1998, Encore
remained obligated to Gould in that amount and had to either pay that amount to
Gould out of its own funds by July 31, 1998 or issue to Gould the overdue
dividend shares of convertible preferred stock, which had a liquidation
preference of $42,678,400. However, in order to give Encore more time to attempt
to resolve Sun's claims, Gould agreed that if Encore issued those dividend
shares to it, Gould would give Encore the option to repurchase the dividend
shares on or before July 31, 1999 for an amount equal to the balance of the
$9,692,000 which remained unpaid plus interest at 8.5% per annum from August 1,
1998. Encore then issued the dividend shares to Gould. On July 31, 1999, Gould
extended Encore's option to repurchase the dividend shares to October 30, 1999;
Gould subsequently extended Encore's option to December 15, 1999, when it
expired.

Sun and Encore entered a Settlement Agreement and Mutual Release pursuant to
which Sun paid Gould an additional $2,500,000 on July 16, 1999 and released
these claims. Therefore, the amount Encore would have to pay Gould to repurchase
the dividend shares is $7,192,000 plus interest of approximately $800,000.

On December 30, 1999, the Company paid $7,192,000 to Gould to settle its
obligation for the amounts withheld by Sun and Gould, among other things, agreed
to convert the dividend shares into common stock.

C.       Sale to Gores Technology

On June 4, 1998, the Company and Gores entered into a definitive agreement for
the Company to sell its real-time business to Gores Technology Group for $3
million in cash.

At the same time the Company entered into the agreement to sell its real-time
computer systems business to Gores, the Company entered into a management
agreement under which Gores took over management of the real-time computer
systems business, retaining any positive cash flow and bearing any negative cash
flow, but receiving a management fee of $100,000 per month, which was to be
refunded to Encore upon closing of the sale of the real-time computer systems
business to Gores. Encore provided a $2 million line of credit to Gores to fund
its operation of the real-time computer systems business until the closing.

                                     Page 9

<PAGE>

The sale of the real-time computer systems business to Gores was approved by the
Company's stockholders on September 11, 1998, and the transaction was completed
on January 6, 1999. At the closing of the sale, the Company received $2,750,000
(with the additional $250,000 set off against the purchase price to resolve an
alleged breach of indemnity claim) and the parties agreed to resolve shortly
after the closing disputed items relating to the sale, including the amounts due
to Encore under the management agreement and the line of credit, and certain
other indemnity claims by Gores. As of May 4, 2000, these items had not yet been
fully resolved.

D.       Accounts Payable and Accrued Liabilities

Accounts payable and accrued liabilities consist of the following (in
thousands):

                                               September 26,     December 31,
                                                   1999             1998
                                                 --------         --------

         Accounts payable                       $  -0-             $   323
         Accrued salaries and benefits             -0-                 299
         Accrued restructuring costs              4,660              3,612
         Accrued liquidation costs                  600              4,609
         Accrued interest-related parties          -0-                 823
         Other accrued expenses                     740                383
                                                -------            -------
                                                $ 6,000            $10,049
                                                =======            =======


E.       Legal Proceedings

Shortly before the Sun transaction was closed, shareholders of the Company
brought a lawsuit in the Delaware Chancery Court against Gould and the Company's
then directors, C. David Ferguson, Robert Fedor, Rowland Thomas and Kenneth
Fisher. Three similar shareholder suits were also filed and all four suits have
been consolidated as Civil Action #16044, In Re Encore Computer Corporation
Shareholders Litigation. The shareholders have filed an amended complaint adding
directors Michael Veysey and Thomas Rich as defendants and eliminating the
Company as other than a nominal defendant. The defendants have moved for summary
judgement and that motion has been argued, but at May 4, 2000 had not yet been
decided. Although the Company is not a party to the litigation, the Company has
indemnified its officers and directors against liability for matters such as
those which are the subject of the litigation. Nonetheless, the Company does not
believe the shareholder suit will have a significant financial impact on the
Company.

                      Management's Discussion and Analysis
                of Financial Condition and Results of Operations

The Company's financial statements are presented on a liquidation basis. See
Management's Discussion and Analysis of Financial Condition and Results of
Operations in the Company's Annual Report on Form 10K for the year ended
December 31, 1998.

The assets of the Company available for distribution to shareholders on
liquidation of Encore would be (i) the Company's assets, less its liabilities,
at September 26, 1999, plus or minus (ii) any sum by which the amount received
from Gores is less than the full amount of the receivable reflected on the
Company's September 26, 1999 balance sheet, plus or minus (iii) any amount by
which severance and other costs related to the sale of the Company's businesses
are less or greater than the accruals for them on the September 26, 1999 balance
sheet, plus or minus (iv) any amount by which the costs of liquidation and costs
related to contingent liabilities, including pending litigation, are less or
greater than the reserves reflected on the September 26, 1999 balance sheet,
minus (v) expenses incurred after September 26, 1999 which have not been
contemplated in the accruals. The amount, if any, of the assets available for
distribution to common shareholders upon liquidation of Encore may depend on
whether Encore repurchases the convertible preferred stock held by Gould or such
preferred stock is otherwise eliminated. Subsequent to September 26, 1999, Gould
converted such preferred stock into 13,295,815 shares of common stock.
