Securities and Exchange Commission on February 5, 1998. The Company assumes no
obligation to update any such forward-looking statement.

RESULTS OF OPERATIONS

FIRST QUARTER 2005 COMPARED WITH FIRST QUARTER 2004

     The Company's net income for the first quarter of 2005 was $4.6 million.
This represented a $1 million or 27% increase from first quarter 2004 earnings
of $3.6 million. Earnings increased primarily because of increased interest
income on earning assets.

                                        6

                      HARRIS PREFERRED CAPITAL CORPORATION

     First quarter 2005 interest income on the Notes totaled $184 thousand and
yielded 6.4% on $11.5 million of average principal outstanding for the quarter
compared to $258 thousand and a 6.4% yield on $16.1 million average principal
outstanding for first quarter 2004. The decrease in income was attributable to a
reduction in the Notes balance because of principal paydowns by customers in the
Securing Mortgage Loans. The average outstanding balance of the Securing
Mortgage Loans for first quarter 2005 and 2004 was $14 million and $20 million,
respectively. Interest income on securities available-for-sale for the current
quarter was $4.6 million resulting in a yield of 4.2% on an average balance of
$436 million, compared to $2.7 million with a yield of 4.4% on an average
balance of $243 million for the same period a year ago. The increase in interest
income is primarily attributable to the increase in the investment portfolio of
mortgage-backed securities.

     There were no Company borrowings during first quarter 2005 or 2004.

     First quarter 2005 operating expenses totaled $134 thousand, a decrease of
$3 thousand or 2% from the first quarter of 2004. Loan servicing expenses
totaled $8 thousand, a decrease of $4 thousand from a year ago. This decrease is
attributable to the reduction in the principal balance of the Notes, thereby
reducing servicing fees payable to the Bank. Advisory fees for the first quarter
2005 were $24 thousand compared to $29 thousand a year earlier. General and
administrative expenses totaled $102 thousand, an increase of $6 thousand over
the same period in 2004 as a result of higher costs for processing,
recordkeeping and administration.

     At March 31, 2005 and 2004, there were no Securing Mortgage Loans on
nonaccrual status.

     On March 30, 2005, the Company paid a cash dividend of $0.46094 per share
on outstanding preferred shares to the stockholders of record on March 15, 2005
as declared on March 2, 2005. On March 31, 2004, the Company paid a cash
dividend of $0.46094 per share on outstanding preferred shares to the
stockholders of record on March 15, 2004, as declared on March 2, 2004.

     At March 31, 2005, net unrealized losses on available-for-sale securities
were $7.7 million compared to $3.1 million of unrealized gains at March 31, 2004
and $1.3 million of unrealized losses at December 31, 2004. The unrealized loss
position at March 31, 2005 was attributable to changes in interest rates and not
to lowered credit quality of individual securities.

LIQUIDITY RISK MANAGEMENT

     The objective of liquidity management is to ensure the availability of
sufficient cash flows to meet all of the Company's financial commitments. In
managing liquidity, the Company takes into account various legal limitations
placed on a REIT.

     The Company's principal asset management requirements are to maintain the
current earning asset portfolio size through the acquisition of additional Notes
or other qualifying assets in order to pay dividends to its stockholders after
satisfying obligations to creditors. The acquisition of additional Notes or
other qualifying assets is funded with the proceeds obtained as a result of
repayment of principal balances of individual Securing Mortgage Loans or
maturities or sales of securities. The payment of dividends on the Preferred
Shares is made from legally available funds, arising from operating activities
of the Company. The Company's cash flows from operating activities principally
consist of the collection of interest on the Notes, mortgage-backed securities
and other earning assets. The Company does not have and does not anticipate
having any material capital expenditures.

     In order to remain qualified as a REIT, the Company must distribute
annually at least 90% of its adjusted REIT ordinary taxable income, as provided
for under the Internal Revenue Code, to its common and preferred stockholders.
The Company currently expects to distribute dividends annually equal to 90% or
more of its adjusted REIT ordinary taxable income.

     The Company anticipates that cash and cash equivalents on hand and the cash
flow from the Notes and mortgage-backed securities will provide adequate
liquidity for its operating, investing and financing needs including the
capacity to continue preferred dividend payments on an uninterrupted basis.

                      HARRIS PREFERRED CAPITAL CORPORATION

     As presented in the accompanying Consolidated Statements of Cash Flows, the
primary sources of funds in addition to $4.7 million provided from operations
during the three months ended March 31, 2005 were $1.1 million provided by
principal repayments on the Notes and $65.3 million from the maturities of
securities available-for-sale. In the prior period ended March 31, 2004, the
primary sources of funds other than $3.4 million from operations were $1.4
million provided by principal repayments on the Notes and $253.2 million from
the maturities and sales of securities available-for-sale. The primary uses of
funds for the three months ended March 31, 2005 were $65.9 million for purchases
of securities available-for-sale and $4.6 million in preferred stock dividends
paid. For the prior year's quarter ended March 31, 2004, the primary uses of
funds were $250.0 million for purchases of securities available-for-sale and
$4.6 million in preferred stock dividends paid.

MARKET RISK MANAGEMENT

     The Company's market risk is composed primarily of interest rate risk.
There have been no material changes in market risk or the manner in which the
Company manages market risk since December 31, 2004.

OTHER MATTERS

     As of March 31, 2005, the Company believes that it is in full compliance
with the REIT tax rules, and expects to qualify as a non-taxable REIT under the
provisions of the Internal Revenue Code. The Company expects to meet all REIT
requirements regarding the ownership of its stock and anticipates meeting the
annual distribution requirements.

     On June 4, 2004, Harris Bankcorp, Inc., the Bank's parent company,
announced its plan to consolidate twenty-six of its separate bank subsidiaries
in Illinois (including the Bank) into one national bank, Harris N.A. This
transaction is expected to be completed in May 2005. After that time, each
outstanding share of the Company's Series A Preferred Stock will be
automatically exchangeable for one newly issued preferred share of Harris N.A.
under the same exchange conditions currently in existence for preferred shares
of the Bank, except that the primary regulator for purposes of the exchange
conditions will be the Office of the Comptroller of the Currency, rather than
the Board of Governors of the Federal Reserve Bank. References herein to the
Bank for those times subsequent to the charter consolidation are intended to
refer to Harris N.A.

FINANCIAL STATEMENTS OF HARRIS TRUST AND SAVINGS BANK

     The following unaudited financial information for the Bank is included
because the Company's preferred shares are automatically exchangeable for a new
series of preferred stock of the Bank upon the occurrence of certain events.

                 HARRIS TRUST AND SAVINGS BANK AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BASIS OF PRESENTATION

     Harris Trust and Savings Bank (the "Bank") is a wholly-owned subsidiary of
Harris Bankcorp, Inc. ("Bankcorp"), a wholly-owned subsidiary of Harris
Financial Corp. (formerly known as Bankmont Financial Corp.), a wholly-owned
subsidiary of Bank of Montreal. The consolidated financial statements of the
Bank include the accounts of the Bank and its wholly-owned subsidiaries.
Significant intercompany accounts and transactions have been eliminated. Certain
reclassifications were made to conform prior year's financial statements to the
current year's presentation.

     The consolidated financial statements have been prepared by management from
the books and records of the Bank, without audit by independent certified public
accountants. However, these statements reflect all adjustments and disclosures
which are, in the opinion of management, necessary for a fair presentation of
the results for the interim periods presented.

     Because the results of operations are so closely related to and responsive
to changes in economic conditions, the results for any interim period are not
necessarily indicative of the results that can be expected for the entire year.

2. LEGAL PROCEEDINGS

     The Bank and certain of its subsidiaries are defendants in various legal
proceedings arising in the normal course of business. In the opinion of
management, based on the advice of legal counsel, the ultimate resolution of
these matters will not have a material adverse effect on the Bank's consolidated
financial position.

3. CASH FLOWS

     For purposes of the Bank's Consolidated Statements of Cash Flows, cash and
cash equivalents is defined to include cash and demand balances due from banks.
Cash interest payments for the three months ended March 31 totaled $86.3 million
and $56.4 million in 2005 and 2004, respectively. Cash income tax payments over
the same periods totaled $11.2 million and $0.5 million, respectively.

4. GOODWILL AND OTHER INTANGIBLE ASSETS

     The Bank records goodwill and other intangible assets in connection with
the acquisition of assets from unrelated parties or the acquisition of new
subsidiaries. Goodwill and other intangible assets that have indefinite useful
lives are not subject to amortization while intangible assets with finite lives
are amortized. Goodwill is periodically assessed for impairment, at least
annually. Intangible assets with finite lives are amortized on either an
accelerated or straight-line basis depending on the character of the acquired
asset. Intangible assets with finite lives are reviewed for impairment when
events or future assessments of profitability indicate that the carrying value
may not be recoverable.

     The carrying value of the Bank's goodwill was $89.3 million as of March 31,
2005 and 2004. No impairment was recorded during the quarter ended March 31,
2005.

     Besides goodwill, the Bank did not have any intangible assets not subject
to amortization as of March 31, 2005 and 2004.

6. SALE OF BUILDING

     On March 1, 2005, the Bank sold to a third party the land and building
located at 111 W. Monroe Street in Chicago. Upon sale, the Bank entered into a
leaseback agreement for approximately 50 percent of the building space with an
average lease term of 16 years. The leaseback agreement meets the criteria to be
recorded as an operating lease. The sale resulted in a gain of $55.8 million,
all of which will be deferred and amortized over the term of the leaseback.

                                FINANCIAL REVIEW

FIRST QUARTER 2005 COMPARED WITH FIRST QUARTER 2004

SUMMARY

     The Bank had first quarter 2005 net income of $25.1 million, a decrease of
$9.9 million or 28 percent from first quarter 2004.

     Cash ROE was 7.26 percent in the current quarter and 10.17 percent in first
quarter 2004. Excluding unrealized gains and losses on the securities portfolio
recorded directly to equity, cash ROE was 7.15 percent for the current year's
first quarter, compared to 10.38 percent a year ago.

     First quarter net interest income on a fully taxable equivalent basis was
$104.8 million, down $3.8 million or 3 percent from $108.6 million in 2004's
first quarter. Average earning assets increased 10 percent to $18.97 billion
from $17.29 billion in 2004. Average loans increased $1.75 billion. Net interest
margin decreased to 2.23 percent from 2.52 percent in the same quarter last year
reflecting the impact of higher rates on deposits, the issuance of higher-cost
incremental supporting funds and little change in the yield from the securities
portfolio. These were somewhat offset by higher yields in the loan portfolio and
a higher loan base.

     In the first quarter 2005, the Bank recorded no provision for loan losses.
The first quarter 2004 provision for loan losses was $17.3 million. Net
charge-offs were $7.5 million compared to $9.3 million in the prior year's
quarter. The decrease in the provision was a result of lower levels of
non-performing loans and an improvement in the credit profile of the loan
portfolio.

     First quarter 2005 noninterest income of $108.9 million decreased $27.7
million from the same quarter last year. Net gains from sales of securities
decreased $11.7 million. In first quarter 2004, the Bank experienced a $7.1
million gain on the sale of assets received in an earlier troubled debt
restructuring and a $7.7 million gain on the termination of a swap.

     First quarter 2005 noninterest expenses of $178.2 million increased $1.9
million or 1 percent from the year-ago quarter. The increase included higher
outsourced administrative and technology expenses. Salary expense decreased from
the prior year's first quarter.

     Nonperforming assets at March 31, 2005 were $134 million or 1.09 percent of
total loans, compared to $125 million or 1.09 percent at December 31, 2004 and
$159 million or 1.56 percent a year ago. At March 31, 2005, the allowance for
loan losses was $212 million, equal to 1.72 percent of loans outstanding,
compared to $244 million or 2.45 percent at the end of first quarter 2004. As a
result, the ratio of the allowance for loan losses to nonperforming assets was
158 percent at March 31, 2005 compared to 153 percent at March 31, 2004.

     At March 31, 2005, Tier 1 capital of the Bank amounted to $1.78 billion, up
from $1.68 billion one year earlier. The regulatory leverage capital ratio was
8.20 percent for the first quarter of 2005 compared to 8.51 percent in the same
quarter of 2004. The Bank's capital ratio exceeds the prescribed regulatory
minimum for banks. The Bank's March 31, 2005 Tier 1 and total risk-based capital
ratios were 9.03 percent and 11.12 percent compared to respective ratios of 9.86
percent and 11.81 percent at March 31, 2004.
