PRESIDENTIAL ASSOCIATES I LIMITED PARTNERSHIP
NOTES TO FINANCIAL STATEMENTS
March 31, 2003
(Unaudited)


1.   ACCOUNTING AND FINANCIAL REPORTING POLICIES

The condensed financial statements included herein have been prepared by the
Partnership, without audit, pursuant to the rules and regulations of the
Securities and Exchange Commission. The Partnership's accounting and financial
reporting policies are in conformity with generally accepted accounting
principles and include all adjustments in interim periods considered necessary
for a fair presentation of the results of operations. Certain information and
footnote disclosures normally included in financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to such rules and regulations. It is suggested that these
financial statements be read in conjunction with the financial statements and
the notes thereto included in the Partnership's Annual Report on Form 10-KSB for
the year ended December 31, 2003.

The accompanying financial statements reflect the Partnership's results of
operations for an interim period and are not necessarily indicative of the
results of operations for the year ending December 31, 2004.

2.   INVESTMENT IN OPERATING PARTNERSHIP

The Partnership accounts for its investment in Presidential Towers, Ltd. (the
"Operating Partnership") using the equity method of accounting. Under the equity
method of accounting, the initial investment is recorded at cost, increased or
decreased by the Partnership's share of income or losses, and decreased by
distributions. Equity in the loss of the Operating Partnership is no longer
recognized once the investment balance reaches zero.

The loss from the Operating Partnership, not recognized since the investment
balance reached zero, will be offset against the Partnership's share of future
income from the Operating Partnership.

3.   TAXABLE LOSS

The Partnership's taxable income for 2004 is not expected to differ from that
for financial reporting purposes.

ITEM 2 - MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION

The matters discussed in this Form 10-QSB contain certain forward-looking
statements and involve risks and uncertainties (including changing market
conditions, competitive and regulatory matters, etc.) The discussion of the
Partnership's business and results of operations, including forward-looking
statements pertaining to such matters does not take into account the effects of
any changes to the Partnership's business and results of operations.
Accordingly, actual results could differ materially from those projected in the
forward-looking statements as a result of a number of factors, including those
identified herein.

This Item should be read in conjunction with the financial statements and other
items contained elsewhere in the report.

Liquidity and Capital Resources

The Partnership's primary source of liquidity is distributions from Presidential
Towers Ltd., an Illinois limited partnership (the "Operating Partnership"). As a
result of a significant restructuring of the ownership and debt of the Operating
Partnership that was finalized in April 1995, the Partnership currently holds a
19.998% limited partnership interest in the Operating Partnership. The
Partnership is responsible for paying various administrative costs associated
with monitoring the Partnership's investment in the Operating Partnership, and
paying various professional fees associated with the affairs of the Partnership.

During the three months ended March 31, 2004 and March 31, 2003, the Operating
Partnership did not make any distributions to the Partnership. In connection
with the April 1995 restructuring, the Partnership is entitled to receive an
annual distribution from the Operating Partnership as a reimbursement of the
Partnership's administrative expenses and professional fees up to an annual
maximum of $30,000 as well as its allocable share of all distributions after a
preferred return to TKI Presidential Partners ("TKI"). In addition, the
Operating Partnership distributes to the Partnership an amount equal to the
amount of income allocated to the Partnership by the Operating Partnership in
each year. On January 10, 2001, the Operating Partnership purchased the two
mortgage notes from HUD by refinancing the Project with a new first mortgage
loan secured by the Project with a third party lender. The new mortgage requires
payments of interest only at a rate of 6.55% per annum and matures on February
1, 2011. As a result of the refinancing, the regulatory agreements with HUD and
the Restructuring Agreement were terminated. Further, as a result of this
refinancing, TKI's priority return was satisfied and the preferred return due
HUD was extinguished. Accordingly, depending on the property's operating
results, it is expected that the Partnership will receive annual distributions
from the Operating Partnership.

The Partnership's liquidity based on cash and cash equivalents decreased by
$1,129 to $1,758,760 at March 31, 2004 as compared to December 31, 2003 due to
operating expenses exceeding interest income by that amount. It is expected that
so long as the Partnership's

PRESIDENTIAL ASSOCIATES I LIMITED PARTNERSHIP
ITEM 2 - MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION (Continued)


Liquidity and Capital Resources (Continued)

administrative expenses do not exceed $30,000 in any year, unless the Operating
Partnership makes a distribution, the Partnership's cash and cash equivalents
will remain relatively constant until the Operating Partnership is liquidated.

The Partnership's liquid assets are currently thought to be sufficient for any
near-term needs of the Partnership.

Results of Operations

Net income decreased by $7,122 for the three months ended March 31, 2004 as
compared to the three months ended March 31, 2003 due to less interest income
earned on the cash accounts and an increase in operating expenses.

ITEM 3 - CONTROLS AND PROCEDURES

The principal executive officer and principal financial officer of the
Partnership's general partner have, within 90 days of the filing date of this
quarterly report, evaluated the effectiveness of the Partnership's disclosure
controls and procedures (as defined in Exchange Act Rules 13a - 14(c)) and have
determined that such disclosure controls and procedures are adequate. There have
been no significant changes in the Partnership's internal controls or in other
factors that could significantly affect such internal controls since the date of
evaluation. Accordingly, no corrective actions have been taken with regard to
significant deficiencies or material weaknesses.
