RESULTS OF OPERATIONS

SECOND QUARTER 2006 COMPARED WITH SECOND QUARTER 2005

     The Company's net income for the second quarter of 2006 was $5.2 million,
an 8% increase from the second quarter 2005 net income of $4.8 million. Earnings
increased primarily because of increased interest income on earning assets.

                                        6
<PAGE>
                      HARRIS PREFERRED CAPITAL CORPORATION

     Interest income on securities purchased under agreement to resell for the
second quarter of 2006 was $1.3 million, on an average balance of $87.8 million,
with an average rate of 5.7%. During the same period in 2005, the interest
income on securities purchased under agreement to resell was $251 thousand on an
average balance of $32.4 million, with an average rate of 3.1%. Second quarter
2006 interest income on the Notes totaled $119 thousand and yielded 6.4% on $7.4
million of average principal outstanding for the quarter compared to $171
thousand and a 6.4% yield on $10.7 million average principal outstanding for
second quarter 2005. The decrease in income was attributable to a reduction in
the Note balance because of principal paydowns by customers on the Securing
Mortgage Loans. Interest income on securities available-for-sale for the current
quarter was $3.9 million resulting in a yield of 4.4% on an average balance of
$359 million, compared to $4.4 million with a yield of 4.1% on an average
balance of $433 million for the same period a year ago. The decrease in the
interest income is primarily attributable to the decrease in the investment
portfolio of mortgage-backed securities.

     There were no Company borrowings during second quarter 2006 or 2005.

     Second quarter 2006 operating expenses totaled $114 thousand, an increase
of $32 thousand or 39% from the second quarter of 2005. Loan servicing expenses
totaled $6 thousand, a decrease of $2 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 second
quarter 2006 were $30 thousand compared to $41 thousand a year earlier. General
and administrative expenses totaled $78 thousand, an increase of $45 thousand
over the same period in 2005 primarily as a result of credits for printing and
processing costs received in 2005 for prior periods.

     At June 30, 2006 and 2005, there were no Securing Mortgage Loans on
nonaccrual status.

     The company classifies all securities as available-for-sale, even if the
Company has no current plans to divest. Available-for-sale securities are
reported at fair value with unrealized gains and losses included as a separate
component of stockholders' equity. At June 30, 2006, net unrealized losses on
available-for-sale securities were $17.1 million compared to $3.5 million of
unrealized losses on June 30, 2005 and $11.0 million of unrealized losses at
December 31, 2005. The unrealized loss positions at June 30, 2006 and 2005 and
December 31, 2005 were attributed to changes in interest rates and not to
lowered credit quality of individual securities; therefore management believes
these unrealized losses are temporary.

SIX MONTHS ENDED JUNE 30, 2006 COMPARED WITH JUNE 30, 2005

     The Company's net income for the six months ended June 30, 2005 was $10.2
million. This represented a $755 thousand increase or 8% from 2005 earnings.
Earnings increased primarily because of an increase in balances of securities
purchased under agreement to resell.

     Interest income on securities purchased under agreement to resell for the
six months ended June 30, 2006 was $2.3 million, on an average balance of $82.6
million, with an average rate of 5.5%. During the same period in 2005, the
interest income on securities purchased under agreement to resell was $451
thousand on an average balance of $32.4 million, with an average rate of 2.8%.
Interest income on the Notes for the six months ended June 30,2006 totaled $249
thousand, yielding 6.4% on $7.8 million of average principal outstanding
compared to $355 thousand of income yielding 6.4% on $11 million of average
principal outstanding for the same period in 2005. The decrease in income was
attributable to a reduction in the Note balance because of customer payoffs on
the Securing Mortgage Loans. The average outstanding balance of the Securing
Mortgage Loans was $10 million for the six months ended June 30, 2006 and $14
million for the same period in 2005. There were no Company borrowings during
either period. Interest income on securities available-for-sale for the six
months ended June 30, 2006 was $7.9 million resulting in a yield of 4.3% on an
average balance of $365 million, compared to $8.8 million resulting in a yield
of 4.1% on an average balance of $435 million a year ago. The decrease in
interest income from available-for-sale securities is primarily attributable to
the decrease in the portfolio of mortgage-backed securities.

                      HARRIS PREFERRED CAPITAL CORPORATION

     Operating expense for the six months ended June 30, 2006 totaled $237
thousand, an increase of $21 thousand from a year ago. Loan servicing expenses
for the six months ended June 30, 2006 totaled $12 thousand, a decrease of $4
thousand or 25% from 2005. This decrease is attributable to the reduction in the
principal balance of the Notes because servicing costs vary directly with these
balances. Advisory fees for the six months ended June 30, 2006 were $61 thousand
compared to $65 thousand a year ago. General and administrative expenses totaled
$164 thousand, an increase of $29 thousand or 21% over the same period in 2005
as a result of increased costs for regulatory filings and prior year credits for
printing and processing costs received in 2005.

     On June 30, 2006, the Company paid a cash dividend of $0.46094 per share on
outstanding Preferred Shares to the stockholders of record on June 15, 2006 as
declared on May 31, 2006. On June 30, 2005, the Company paid a cash dividend of
$0.46094 per share on outstanding Preferred Shares to the stockholders of record
on June 15, 2005, as declared on June 2, 2005.

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 and U.S Treasury securities will provide
adequate liquidity for its operating, investing and financing needs including
the capacity to continue preferred dividend payments on an uninterrupted basis.

     As presented in the accompanying Consolidated Statements of Cash Flows, the
primary sources of funds in addition to $10.2 million provided from operations
during the six months ended June 30, 2006 were $1.5 million provided by
principal repayments on the Notes and $198.8 million from the maturities of
securities available-for-sale. In the prior period ended June 30, 2005, the
primary sources of funds other than $9.3 million from operations were $1.6
million provided by principal repayments on the Notes and $113.9 million from
the maturities of securities available-for-sale. The primary uses of funds for
the six months ended June 30, 2006 were $205.2 million for purchases of
securities available-for-sale and $9.2 million in preferred stock dividends
paid. For the prior year's period ended June 30, 2005, the primary uses of funds
were $113.2 million for purchases of securities available-for-sale and $9.2
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, 2005.

OTHER MATTERS

     As of June 30, 2006, 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.

     The preparation of consolidated financial statements in conformity with
accounting principles generally accepted in the United States of America,
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities and disclosure of contingent assets and
liabilities at the date of the consolidated financial statements and the
reported amounts of revenues and expenses during the reporting period. Actual
results could differ from those estimates.

                          HARRIS N.A. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BASIS OF PRESENTATION

     Harris N.A. (the "Bank") is a wholly-owned subsidiary of Harris Bankcorp,
Inc. ("Bankcorp"), a wholly-owned subsidiary of Harris Financial Corp., a
wholly-owned U.S. 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.

     On February 17, 2006 Bankcorp merged one of its bank subsidiaries, New
Lenox State Bank, with and into Harris N.A. This transaction was recorded at its
carrying value and prior year financial statements have been restated.

     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 six months ended June 30 totaled $476.7 million
and $263.1 million in 2006 and 2005, respectively. Cash income tax payments over
the same periods totaled $65.8 million and $40.2 million, respectively.

                                FINANCIAL REVIEW

SECOND QUARTER 2006 COMPARED WITH SECOND QUARTER 2005

SUMMARY

     The Bank had second quarter 2006 net income of $51.8 million, a decrease of
$8.6 million or 14 percent from second quarter 2005. Return on equity was 6.90
percent in the current quarter, compared to 8.62 percent from last year's second
quarter. Return on assets was 0.56 percent compared to 0.71 percent a year ago.

     Second quarter net interest income on a fully taxable equivalent basis was
$212.7 million, up $6.2 million or 3 percent from $206.5 million in 2005's
second quarter. Average earning assets increased 10 percent to $33.57 billion
from $30.61 billion in 2005, due primarily to an increase of $2.6 billion in
average loans. Net interest margin decreased to 2.54 percent in the current
quarter from 2.70 percent in the year-ago quarter, primarily reflecting a flat
yield curve that depressed spreads on earnings assets and the impact of greater
reliance on higher-cost wholesale funding sources. This was somewhat offset by
strong loan growth, particularly in the retail loan portfolio, which are
generally higher yielding earnings assets.

     The second quarter 2006 provision for loan losses was $5.7 million compared
to $2.1 million in the second quarter of 2005. Net charge-offs increased to $8.2
million from $2.3 million in the prior year. The credit profile of the loan
portfolio is expected to remain solid with moderate increases in default and
loss experiences in late 2006. The increase in the provision in the second
quarter of 2006 reflected charge-off activity and management's assessment of
non-performing loans.

     Noninterest income was $101.4 million, a decrease of $4.4 million or 4
percent from the same quarter last year. This was primarily attributable to a
$5.9 million decline in intercompany service income, a $2.5 million decrease in
referral fees and a $1.3 million decrease in trust and investment management
fees. The decreases were partially offset by a $2.3 million increase in net
securities gains, a $1.6 million increase in money market and bond trading
income and $1.0 million higher in bank-owned insurance income.

     Second quarter 2006 noninterest expenses of $223.9 million increased $6.3
million or 3 percent from the year ago quarter. The increase was primarily
attributable to intercompany service costs rising by $7.7 million and a $2.5
million increase in equipment expenditures. The increases were partially offset
by reduced salaries and other compensation expenses. Income tax expense
decreased $1.5 million, reflecting lower pretax income from prior year's
results. The effective tax rate was higher in this year's quarter as a result of
current second quarter settlements for prior years' tax returns.

     Nonperforming assets at June 30, 2006 were $125 million or 0.50 percent of
total loans, down from $169 million or 0.69 percent at March 31, 2006, and $146
million or 0.65 percent a year ago. At June 30, 2006, the allowance for loan
losses was $319 million, equal to 1.28 percent of loans outstanding, compared to
$315 million or 1.41 percent of loans outstanding at the end of second quarter
2005. As a result, the ratio of the allowance for loan losses to nonperforming
assets increased from 215 percent at June 30, 2005 to 255 percent at June 30,
2006.

     At June 30, 2006, Tier 1 capital of the Bank amounted to $3.12 billion, up
from $2.83 billion one year earlier. The regulatory leverage capital ratio was
8.48 percent for the second quarter of 2006 compared to 8.43 percent in the same
quarter of 2005. The Bank's capital ratio exceeds the prescribed regulatory
minimum for banks. The Bank's June 30, 2006 Tier 1 and total risk-based capital
ratios were 9.84 percent and 11.77 percent compared to respective ratios of 9.92
percent and 12.05 percent at June 30, 2005.

SIX MONTHS ENDED JUNE 30, 2006 COMPARED WITH JUNE 30, 2005

SUMMARY

     The Bank had net income for the six months ended June 30, 2006 of $93.2
million, a decrease of $21.8 million or 19 percent from the same period a year
ago. Return on equity was 6.31 percent in the current

year, compared to 8.28 percent from last year. Return on assets was 0.52 percent
compared to 0.70 percent a year ago.

     Net interest income on a fully taxable equivalent basis was $423.1 million,
up $14.4 million or 4 percent from $408.7 million in 2005's year-to-date period.
Average earning assets increased 10 percent to $32.98 billion from $30.07
billion in 2005. Loan growth of 4.77% fueled the increase in earnings assets.
Net interest margin decreased to 2.58 percent from 2.73 percent in 2005,
reflecting the impact of higher rates on deposits and the issuance of
higher-cost wholesale supporting funds. This was somewhat offset by higher
yields in the loan portfolio and strong retail loan growth.

     The year-to-date 2006 provision for loan losses was $11.3 million compared
to $5.1 million in 2005, an increase of $6.2 million. Net charge-offs were $15.9
million, an increase of $4.7 million from last year, resulting primarily from
higher retail loan write-offs. The increase in provision resulted from increased
net charge-offs and management's assessment of non-performing loans.

     Noninterest income of $185.3 million decreased $23.8 million or 11 percent
from the same period last year. This was primarily attributable to a $9.5
million decline in trust and investment management fees a $9.3 million decrease
in intercompany service income, a $3.2 million prior year gain on a loan sale
and lower indirect loan and referral fees. The decreases were partially offset
by a $2.6 million increase in service charges and fees and a $2.4 million
increase in net securities gains.

     Noninterest expenses of $451.0 million increased $15.4 million or 4 percent
from the year-ago period. The increase was attributable to intercompany service
costs rising by $11.9 million and a $5.3 increase in expert service fees, as
well as increases in most expense categories. These increases were primarily
offset by reduced salaries and other compensation expenses. Income tax expense
decreased $12.8 million, reflecting lower pretax income from year ago results.
