         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

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

on trading securities. At June 30, 1999 the Company had no open trading or
investment positions. During the quarter the Company realized a gain of $8,000

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

         Liquidity and Capital Resources

         At June 30, 1999, the Company had a cash and Treasury Bill balance of
$5,617,000, which represents an $231,000 increase from the $5,386,000 balance at
September 30, 1998. This $231,000 increase results entirely from cash flow from
operations which includes the result of a net profit of $210,000 and changes in
operating assets and liabilities of $21,000. The Company's working capital
position at June 30, 1999 was $6,355,000 as compared to a September 30, 1998
balance of $6,145,000.

         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 expects no adverse impact from the Year 2000 computer
issue. 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 that is expected to be completed in fiscal 1999.

         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
realized a gain of $8,000 on its trading and investment activities as compared
with no gain or loss in the prior year period. During the quarter the Company's
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, 1999, the Company had
approximately 80% of its assets in United States Treasury Bills. At June 30,
1999 the Company had no outstanding investment or trading positions.

Results of Operations

Three Months Ended June 30, 1999

Net income (loss)

         The Company recorded income of $50,000 in the current three-month
period versus a profit of $52,000 in the prior year period. Interest income
decreased $16,000 to $63,000 primarily due to lower interest rates. Trading
gains in the current quarter were $8,000 compared to no gain or loss in the
prior year period. General and administrative expenses of $21,000 were $6,000
lower than the prior year period of $27,000. The decrease of $6,000 was due
primarily to a lower level of insurance costs and professional fees.

         During the current and prior year quarter the Company did not record an
income tax provision/benefit due to its tax carryforward position at that time.
