ENCORE COMPUTER CORPORATION

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

A.       Nature of Operations and Summary of Significant Accounting Policies

Nature of Operations
Encore Computer Corporation, founded in 1983, designed, manufactured,
distributed and supported scalable real-time data systems and advanced
clustering technologies. Headquartered in Fort Lauderdale, Florida, the company
had sales offices and distributors in the United States, Canada, Europe, and the
Far East.

Significant Accounting Policies
The condensed consolidated financial statements include the accounts of Encore
Computer Corporation and its subsidiaries (collectively, "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, 2001.

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 sold substantially all of its storage products
business assets to Sun Microsystems, Inc. ("Sun"). Furthermore, during fiscal
1998, the Company sold its real-time computer systems business to Gores
Technology Group. 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

                                     Page 5

<PAGE>


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 on or about June
30, 1999, and the Company's further activities are conducted in space provided
by Gould Electronics Inc. ("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.

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 June 30, 2002, plus or minus (ii) any amounts 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 June 30, 2002
statement of net assets in liquidation, minus (iii) expenses incurred after June
30, 2002 which have not been contemplated in the accruals. See Note F for a
discussion of the proposed resolution of litigation and dissolution of the
Company.

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

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, of
the estimated realizable values of assets, 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 June
30, 2002.

Accounts payable and accrued liabilities as of June 30, 2002 include estimates
of costs to be incurred in carrying out the liquidation of the Company. The
actual costs could vary significantly from the related provisions due to
uncertainty related to the length of time required to liquidate the Company and
complexities and contingencies.

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.

In connection with the sale of Encore's storage product 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 were challenged in an insolvency proceeding
relating to Encore commenced within two years after 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. On July 16, 1999, Sun and Encore entered
a Settlement Agreement and Mutual Release pursuant to which Sun paid $2,500,000
to Gould as a settlement for the receivable and Sun released these claims. Sun
did not release Gould's other indemnification obligations related to Encore's
obligations under the Asset Purchase Agreement.

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 7

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 over-due
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 ($7,192,000 after the payment of $2,500,000
received on July 16, 1999) 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.

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 and agreed that if
Encore were liquidated before November 24, 2000, 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. Additionally,
Gould agreed to indemnify Encore for any obligations it might incur to indemnify
its current and future directors, up to a total of $7,192,000. On January 20,
2000, Gould converted its convertible preferred stock to 13,295,815 shares of
common stock.

C.       Sale to Gores Technology

When the Company completed the sale of its storage products business, the Board
of Directors decided that, at least until the Board's January 1998 meeting, the
Company should (a) explore the possibility of attempting to develop and market
clustering software related to Windows NT(R) and (b) explore the feasibility of
the Company's continuing, and attempting to expand, its real-time computer
systems business. In January 1998, the Board of Directors (i) decided the
Company should discontinue its efforts to develop clustering software relating
to Windows NT and (ii) authorized the Company to retain an investment banker to
try to find a purchaser for the real-time computer systems business.

On March 2, 1998, the Company signed a non-binding letter of intent to sell its
real-time computer systems business to Gores Technology Group ("Gores") for
approximately $5.5 million, based on an estimated December 31, 1997 balance
sheet for that business. On June 4, 1998, the Company and Gores entered into a
definitive agreement for the Company to sell the real-time business to Gores for
$3 million in cash. The reduction in price from that contemplated in the letter
of intent reflected operating results during the first quarter of 1998 and
differences between the estimated December 31, 1997 balance sheet and the actual
balance sheet at March 29, 1998.

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.

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. On August 10, 2000, the Company reached an
agreement in principle to resolve such items. In connection with the agreement,
Encore and Gores agreed to reduce the principal balance of the receivable by (1)
$96,000 relating to an uncollectible note receivable purchased by Gores in the
acquisition of the real-time business and (2) $150,000 for expenses incurred in
the negotiation of this settlement. As a result, the receivable balance due to
Encore was $2,979,000.

In order to reduce this balance, Gores agreed to make payments on Encore's
behalf relating to the closing of certain foreign offices. Such payments
included lease termination fees and payment of taxes. During fiscal 1999, Gores
paid $35,000 relating to the termination of Encore's Belgium office lease. As a
result, the outstanding balance of the receivable was $2,944,000 as of December
31, 1999.

Subsequent to December 31, 1999, Gores paid approximately $1,845,000 relating to
lease termination costs and a tax settlement. After these payments, the
receivable balance amounted to $1,098,000. Gores agreed to make cash payments
for the remainder of the receivable balance. In August and October 2000, Encore
received payments totaling $500,000 toward the receivable balance. In February
2001, the Company received the remaining $598,000 plus an additional $16,000.

D.       Accounts Payable and Accrued Liabilities

During the three months ended June 30, 2002, the Company paid $126,000 of
previously accrued liquidation costs.

E.       Other Adjustments

During the three months and six months ended June 30, 2002, the Company received
$6,000 and $45,000, respectively, for various refunds and reimbursements of
amounts previously paid. Based on revised estimates of liquidation costs, the
Company accrued an additional $19,000 during the three months ended June 30,
2002.

F.       Litigation

Shortly before the Sun Transaction was closed, shareholders of the Company
brought a derivative suit 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 were consolidated as Civil Action #16044, In Re Encore Computer
Corporation Shareholders Litigation. The shareholders 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 moved for summary
judgment and that motion was granted on June 16, 2000. Two of the plaintiffs
filed a notice of appeal in the Delaware Supreme Court. 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. On July 6, 2001, the parties reached a proposed settlement that,
upon court approval, would have provided for a repurchase by the Company and
redistribution to class members of the defendants' common stock holdings in the
Company and the individual defendants' resignation from their positions with the
Company in favor of the plaintiffs' nominees. At a hearing on October 12, 2001,
the court did not grant its approval to the proposed settlement. Attorneys for
parties to the lawsuit and for two shareholders who objected to the settlement
have reached an agreement to resolve the litigation and the objectors'
contentions under which the Company would be dissolved; $2.1 million of
distributable assets (less certain attorneys' fees and expenses) would be
distributed to current shareholders and the defendant shareholders, at the time
of dissolution; a fund of up to $100,000 would be set aside for certain claims
of former shareholders, the balance of the distributable assets would be
distributed to Gould; and all claims would be dismissed and released as to the
defendants and their privies. The record date for the vote on the dissolution
has not yet been set. The agreement, which was signed on June 29, 2002, is
subject to court approval; a hearing has been scheduled for October 2, 2002.
Nonetheless, the Company does not believe the shareholder suit will have a
significant financial impact on the Company. The defendants own approximately
63% of the outstanding common stock of the Company.
