                                   (Unaudited)



1.  BASIS OF PRESENTATION

         The balance sheet at the end of the preceding fiscal year has been
derived from the audited balance sheet contained in the Company's Form 10-K and
is presented for comparative purposes. All other financial statements are
unaudited. In the opinion of management, all adjustments which include only
normal recurring adjustments necessary to present fairly the financial position,
results of operations and cash flows for all periods presented have been made.
The results of operation for interim periods are not necessarily indicative of
the operating results for the full year.

         Footnote disclosures normally included in financial statements prepared
in accordance with generally accepted accounting principles have been omitted in
accordance with the published rules and regulations of the Securities and
Exchange Commission. These financial statements should be read in conjunction
with the financial statements and notes thereto included in the Company's Form
10-K for the most recent fiscal year.

2.  TRADING SECURITIES

         For the three months ending June 30, 1998 and 1997, there was no charge
or credit to earnings representing the change in the net unrealized holding loss
on trading securities. At June 30, 1998 the Company had no open trading or
investment positions. During the quarter the Company incurred no gain or loss on
its trading and investment activities as compared with a loss of $13,000 in the
prior year period. During the quarter the Company's had no exposure to financial
derivatives.

         At June 30, 1998 approximately 80% of total Company's assets were held
in United States Treasury Bills. Since it is the intention of the Company to
acquire or develop an operating business, the Company presently intends to risk
no more than 15% of net worth in trading or investment activities.

3.  PROPERTY HELD FOR DEVELOPMENT AND SALE

         The Company presently owns one property in Washington D.C., which it
    acquired with the intention to improve and resell. The property is in the
    process of renovation. The Company is evaluating its experience in the real
    estate improvement business and will decide during the next several months
    whether to continue or expand this activity.

Item 2.  Management's Discussion and Analysis of Financial Condition and
         Results of Operations

         Liquidity and Capital Resources

         At June 30, 1998, the Company had a cash and Treasury Bill balance of
$5,772,000 which represents an $345,000 decrease from the $6,117,000 balance at
September 30, 1997. This $345,000 decrease results from cash flow from
operations of $434,000 which includes the result of a net loss of $256,000 and
changes in operating assets and liabilities of $96,000 offset by the net
proceeds from the sale of a property for $786,000. In addition, cash flow used
for financing activities accounted for $779,000 representing the net activity of
repurchasing and canceling of outstanding shares for $884,000 offset by the
proceeds received from President John Michael for the exercise of stock options
in the amount of $105,000. The shares repurchased included 138,211 shares
repurchased from two unrelated parties at $1.20 per share or $166,000 and
598,389 shares repurchased from Company President John H. Michael at $1.20 per
share or $718,000. At June 30, 1998 the Company had no outstanding stock
options. The Company's working capital position at June 30, 1998 was $6,520,000
as compared to a September 30, 1997 balance of $7,555,000.

         Management intends to continue in business and has no intention to
liquidate the Company. The Company has considered various business alternatives
including the possible acquisition of an existing business, but to date has
found possible opportunities unsuitable or excessively priced. The Company is
also considering developing a business itself, believing that start up costs may
be preferable to the premiums required to purchase a going concern. The Company
does not contemplate limiting the scope of its search to any particular
industry. Management has considered the risk of possible opportunities as well
as their potential rewards. Management has invested considerable time evaluating
and finally rejecting numerous proposals for possible acquisition or
combination. The Company believes present valuation levels requested for
alternative operating entities are excessive partly due to the expectations of
sellers being raised by generally high stock market valuations. The Company has
decided to focus its present operating activities on the acquisition,
improvement and resale of real property. This decision does not preclude the
possibility of becoming involved in the future with additional businesses in
other areas.

         The Company presently owns one property in Washington D.C. which it
acquired with the intention to improve and resell. The property is in the
process of renovation. The Company is presently evaluating its experience in the
real estate improvement business and will decide during the next several months
whether to continue this activity.

         The Company intends to continue its investing and trading activities
and as a consequence the future financial results of the Company may be subject
to substantial fluctuations. Mr. Michael, the President of the Company is a
graduate of Harvard Business School (MBA). As part of the Company's investment
activities the Company may buy and sell a variety of equity, debt or derivative
securities including market index options and future contracts. Such investment
often involves a high degree of risk and must be considered extremely
speculative. Futures Contracts are particularly risky since a relatively small
amount of capital controls a large nominal market value thus greatly
exaggerating the exposure to potential losses. During the quarter the Company
incurred no gain or loss on its trading and investment activities as compared
with a loss of $13,000 in the prior year period. During the quarter the Company
had no exposure to financial derivatives.

         The focus of the Company's efforts is to acquire or develop an
operating business. The Company presently intends to risk no more than 15% of
net worth in trading or investment activities. At June 30, 1998, the Company had
approximately 80% of its assets in United States Treasury Bills. At June 30,
1998 the Company had no outstanding investment or trading positions.

                                                                  Page 7 of 10

Results of Operations

Three Months Ended June 30, 1998

Net income (loss)

         The Company recorded income of $52,000 in the current three-month
period versus a loss of $78,000 in the prior year period. Interest income
increased $11,000 to $79,000 primarily due to more invested funds. There was no
trading activity in the current quarter compared to trading losses of $13,000 in
the prior year period. General and administrative expenses of $27,000 were
$106,000 lower than the prior year period of $133,000. The reduction of $106,000
was due primarily to lower insurance costs and a lower level of compensation
paid to President John Michael. During the current quarter the Company recorded
a $50,000 reduction in insurance costs. During the prior year quarter Mr.
Michael received a special investment performance bonus of $50,000 related to
trading gains realized in the prior year period.

         During the current and prior year quarter the Company had not recorded
an income tax provision/benefit due to unavailable tax carryforwards.

Results of Operations

Nine  Months Ended June 30, 1998


Net income (loss)

         The Company incurred a loss in the current nine-month period of
$256,000 versus a gain of $83,000 in the prior year period. Interest income
increased $31,000 to $246,000 primarily due to more invested funds. Trading
losses equaled $323,000 compared to trading gains of $691,000 in the prior year
period. General and administrative expenses of $179,000 were $644,000 lower than
the prior year period of $823,000. The reduction of $644,000 was due primarily
to a lower level of compensation paid to President John Michael and a lower
level of real estate development activity. During the current nine-month period
Mr. Michael received compensation of $131,000 as compared to compensation of
$531,000 (which included a special investment performance bonus of $400,000
which was paid to Mr. Michael in connection with trading gains realized in the
prior year period). In addition, general and administrative expenses were
$244,000 lower in the current nine-month period due to lower insurance and
professional costs and a lower level of real estate development activity which
last year included a special allowance of $120,000 for the diminished value of
one of the Company's real estate properties.

         During the current and prior year nine-month period the Company had not
recorded an income tax benefit due to unavailable tax carryforwards.
