   UnionBanCal Corporation (NYSE:UB) today reported first quarter
2006 net income of $172.9 million, or $1.18 per diluted common share,
and income from continuing operations of $181.5 million, or $1.24 per
diluted common share. Excluding a positive tax adjustment of $0.07 per
diluted common share last year, first quarter 2006 income from
continuing operations per diluted common share increased 9.7 percent.
   "We are off to a good start in 2006," stated Takashi Morimura,
President and Chief Executive Officer. "Our balanced business model is
evident in our first quarter results as excellent loan growth and
credit quality offset mixed deposit results, reflecting an
increasingly competitive deposit market. During the quarter, we
returned $139 million to shareholders in the form of dividends and
share repurchases, equal to 80 percent of our first quarter net
income. Despite this significant return of capital, we finished the
quarter with very strong capital levels, including a tangible equity
ratio of 8.46 percent."
   "We generated good loan growth across all categories in first
quarter," added Chief Operating Officer Philip Flynn. "Commercial
loans increased at a double digit rate, and, though slowing
appreciably due to rising rates, residential mortgages still grew at a
healthy rate year-over-year. We continue to report very strong credit
quality, with net charge-offs of only $5 million in the quarter and
nonperforming assets declining further, to just 0.09 percent of total
assets at quarter-end. While this trend is unsustainable in the long
run, it is evidence of our responsible lending and monitoring
practices and the overall quality of our loan portfolio.
   "Average noninterest bearing deposits declined 9 percent versus
the fourth quarter, virtually all due to a decline in wholesale
deposits," continued Flynn. "Well over half of the decline in the
wholesale deposit base was in title, escrow and other real estate
related balances, reflecting slower real estate activity, some of
which is seasonal. In addition, demand deposit volumes were affected
by disintermediation, which has accelerated due to the cumulative
effect of rising short-term interest rates. Despite this more
challenging deposit environment, our deposit franchise remains healthy
and will continue to afford us a solid advantage in our primary
markets. We have built this deposit franchise over the long term, and
the inherent strength in this aspect of our business will serve the
Company very well going forward. We are confident that we can defend
and continue to grow our deposit base, and we took steps to do just
that in the quarter by launching several new interest bearing deposit
initiatives."

   First Quarter Total Revenue From Continuing Operations

   For first quarter 2006, total revenue (taxable-equivalent net
interest income plus noninterest income) was $684 million, an increase
of $42 million, or 6.5 percent, compared with first quarter 2005. Net
interest income increased 6.8 percent, and noninterest income
increased 6.0 percent. Compared with fourth quarter 2005, total
revenue increased 2.9 percent, with net interest income decreasing 3.2
percent, and noninterest income increasing 18.8 percent. Excluding a
$37 million fourth quarter 2005 loss on the sale of securities, total
revenue in sequential quarters decreased $18 million, or 2.5 percent,
with net interest income decreasing 3.2 percent and noninterest income
decreasing 1.1 percent.

   First Quarter Net Interest Income (Taxable-equivalent) From
Continuing Operations

   Net interest income was $466 million in first quarter 2006, up $30
million, or 6.8 percent, from the same quarter a year ago, primarily
due to strong growth in loans.
   Average earning assets increased $1.4 billion, or 3.4 percent,
primarily due to a $4.3 billion, or 14.6 percent, increase in average
loans, while average securities declined $2.9 billion, or 25.8
percent. Average commercial loans increased $2.0 billion, or 19.7
percent; average residential mortgages increased $1.6 billion, or 16.4
percent; average construction loans increased $0.4 billion, or 36.7
percent; and average commercial mortgages increased $0.2 billion, or
4.3 percent.
   Compared to first quarter 2005, average noninterest bearing
deposits decreased $649 million, or 3.6 percent. Average title and
escrow deposits decreased $381 million, or 13.8 percent, due to lower
residential real estate activity. Average business demand deposits,
excluding title and escrow, declined $305 million, or 2.5 percent,
primarily due to disintermediation resulting from rising short-term
interest rates. Consumer deposits increased $37 million, or 1.2
percent. Average noninterest bearing deposits represented 45.1 percent
of average total deposits in first quarter 2006. The annualized
average all-in cost of funds was 1.45 percent, reflecting the
Company's strong average deposit-to-loan ratio of 114.1 percent and
the high proportion of noninterest bearing deposits to total deposits.
   The average yield on earning assets of $43.1 billion was 5.77
percent, up 83 basis points over first quarter last year, with the
average loan yield increasing 58 basis points. The average rate on
interest bearing liabilities of $24.5 billion was 2.49 percent, up 118
basis points, reflecting both higher short-term interest rates and
heightened competition for deposits, compared with first quarter 2005.
Average interest bearing deposits were $21.3 billion and the weighted
average rate was 2.19 percent. The net interest margin in first
quarter 2006 was 4.36 percent, compared with 4.22 percent in first
quarter 2005, an increase of 14 basis points.
   On a sequential quarter basis, net interest income decreased $15
million, or 3.2 percent, with approximately $5 million of the variance
due to two less days in the quarter. Average loans increased $791
million, or 2.4 percent, while average securities decreased $794
million, or 8.7 percent. Average commercial loans increased $389
million, or 3.3 percent; average residential mortgages increased $301
million, or 2.7 percent; and average construction loans increased $109
million, or 7.7 percent. Average noninterest bearing deposits
decreased $1.7 billion, or 9.1 percent, primarily due to a $766
million decrease in title and escrow deposits and disintermediation in
other business demand deposits caused by rising short-term interest
rates. The impact of lower title and escrow deposit volumes was
partially offset by a reduction in noninterest expense associated with
this business. The average yield on earning assets increased 26 basis
points and the average rate on interest bearing liabilities increased
44 basis points. The net interest margin decreased 6 basis points to
4.36 percent, primarily due to lower demand deposits.

   First Quarter Noninterest Income From Continuing Operations

   In first quarter 2006, noninterest income was $218 million, up $12
million, or 6.0 percent, from the same quarter a year ago. Service
charges on deposit accounts increased 3.0 percent, primarily due to
changes in the overdraft and NSF fee structure, partially offset by
lower account analysis fees stemming from an increase in the earnings
credit rate on deposit balances. Trust and investment management fees
increased $8.2 million, or 19.4 percent, primarily due to an increase
in trust assets and to a one-time increase in trust fees resulting
from a refinement in accrual methodology, which accounted for $3
million of the increase.
   Compared with fourth quarter 2005, first quarter 2006 noninterest
income increased $34 million, or 18.8 percent. Excluding the $37
million loss on the sale of $1 billion of agency debentures associated
with the strategic rebalancing of the Company's securities portfolio
in fourth quarter 2005, noninterest income decreased $2 million, or
1.1 percent. Service charges on deposit accounts increased 2.0
percent, while trust and investment management fees increased 7.9
percent, primarily due to a refinement in accrual methodology. Other
noninterest income declined $7.4 million, or 17.0 percent, primarily
due to a decline in net gains on private equity investments of $5.5
million.

   First Quarter Noninterest Expense From Continuing Operations

   Noninterest expense for first quarter 2006 was $415 million, an
increase of $22 million, or 5.5 percent, over first quarter 2005.
Salaries and employee benefits expense increased $21 million, or 9.0
percent, primarily due to annual merit increases and higher
performance-related incentive expense. Higher incentive expense
included $6.2 million in stock option expense, recorded for the first
time in first quarter 2006, and a $2.9 million increase in restricted
stock expense, as the Company has moved to a heavier restricted stock
weighting in its equity-linked compensation programs. Professional
services expense increased $3 million, or 23.9 percent, primarily due
to higher compliance-related expense. Outside services expense
increased $7 million, or 34.7 percent, primarily due to higher cost of
services related to title and escrow balances, stemming from a higher
earnings credit rate in first quarter 2006. Foreclosed asset expense
(income) in first quarter 2006 reflects a $7.4 million gain on the
sale of property. The provision for off-balance sheet commitments
declined $6 million compared with first quarter 2005.
   Excluding the effect of stock option expense and higher restricted
stock expense, noninterest expense increased $12 million, or 3.2
percent, compared with prior year.
   Compared with fourth quarter 2005, noninterest expense decreased
$15 million, or 3.4 percent. Salaries and employee benefits expense
increased $20 million, or 8.6 percent, primarily due to annual
seasonal factors that result in higher payroll taxes and 401(k)
matching contributions, as well as the initial expensing of stock
options in the first quarter. Payroll taxes accounted for $9.5 million
of the increase, 401(k) and post-employment expense accounted for $7.3
million of the increase, and stock option expense accounted for $6.2
million of the increase. Net occupancy expense decreased $8 million,
or 20.0 percent, primarily due to charges incurred in fourth quarter
2005 associated with the consolidation of offices in San Francisco.
Professional services expense increased $5 million, or 55.3 percent,
primarily due to a recovery of legal fees recorded in fourth quarter
2005 and higher compliance-related expense in the first quarter.
Outside services expense decreased $12 million, or 30.1 percent,
primarily due to lower cost of services related to decreased title and
escrow balances. Foreclosed asset expense (income) in first quarter
2006 reflects a $7.4 million gain on the sale of property. The
provision for off-balance sheet commitments declined $8 million
compared with fourth quarter 2005.

   Income Tax Expense From Continuing Operations

   The effective tax rate for first quarter 2006 was 34.1 percent,
compared with an effective tax rate of 31.0 percent for first quarter
2005. First quarter 2005 income tax expense included a $10.0 million
reduction in reserves for estimated amounts owed to the Internal
Revenue Service with respect to certain leveraged leasing
transactions.

   Credit Quality

   Nonperforming assets at March 31, 2006, were $42 million, or 0.09
percent of total assets. This compares with $62 million, or 0.12
percent of total assets, at December 31, 2005, and $101 million, or
0.20 percent of total assets, at March 31, 2005. Nonperforming assets
declined 58 percent between March 31, 2005 and March 31, 2006.
   In first quarter 2006, the total provision for credit losses was
negative $10.0 million. The total provision for credit losses was
negative $5.0 million in fourth quarter 2005 and negative $9.1 million
in first quarter 2005. The total provision for credit losses in first
quarter 2006 consisted of a provision for loan losses of negative $7.0
million and a provision for off-balance sheet commitments (classified
in noninterest expense) of negative $3.0 million. In first quarter
2006, net charge-offs were $5 million, compared with net charge-offs
of $2 million in fourth quarter 2005, and net recoveries of $15
million in first quarter 2005.
   At March 31, 2006, the allowance for credit losses as a percent of
total loans and as a percent of nonaccrual loans was 1.26 percent and
1003 percent, respectively. These ratios were 1.32 percent and 744
percent, respectively, at December 31, 2005, and 1.63 percent and 507
percent, respectively, at March 31, 2005.

   Balance Sheet and Capital Ratios

   At March 31, 2006, the Company had total assets of $48.8 billion.
Total loans were $33.5 billion and total deposits were $39.2 billion,
resulting in a period-end deposit-to-loan ratio of 117 percent. At
period-end, total stockholders' equity was $4.6 billion, the tangible
equity ratio was 8.46 percent, and the ratio of tangible common equity
to risk-weighted assets was 8.68 percent. Book value per share at
March 31, 2006, was $31.94, up 12.4 percent from a year earlier. The
Company's Tier I and total risk-based capital ratios at period-end
were 9.01 percent and 10.84 percent, respectively.

   Stock Repurchases

   During first quarter 2006, the Company repurchased 1,167,700
shares of common stock at a total price of $80.0 million, or an
average of $68.52 per repurchased share. At March 31, 2006, the
Company was authorized by its Board of Directors to repurchase an
additional $22 million of common stock.
   Common shares outstanding at March 31, 2006, were 143.4 million, a
decrease of 1.2 million shares, or 0.8 percent, from one year earlier.

   Discontinued Operations

   On September 22, 2005, the Company announced the signing of a
definitive agreement to sell its international correspondent banking
business (the Business) to Wachovia Bank, N.A. The principal legal
closing of the transaction took place on October 6, 2005, with the
Company receiving $245 million in cash from Wachovia. The Company is
continuing to operate the Business over a transition period which will
extend into the second quarter of 2006, during which time it is
expected that the majority of the Company's international
correspondent bank customers will have transferred to Wachovia. The
Company expects its exit from international correspondent banking to
be complete in the second quarter of 2006.
   As customers have transferred to Wachovia, the Company's
international correspondent banking revenue has declined.
International correspondent banking expenses have also declined,
though at a slower rate than revenue. Commencing in third quarter
2005, all results of the international correspondent banking business
have been reported as a discontinued operation and all prior periods
have been restated to reflect this accounting treatment. All of the
assets and liabilities of the discontinued operations have been
separately identified on the consolidated balance sheets (see Exhibit
3) and the average net assets or liabilities of the discontinued
operations are reflected in the analysis of net interest margin (see
Exhibits 5 and 6).
   In the first quarter of 2006, the Company recorded a net loss from
discontinued operations of $8.5 million, or $0.06 per fully diluted
common share. In the fourth quarter of 2005, the Company recorded an
after-tax gain on the transaction of approximately $147.4 million, or
$1.00 per fully diluted share, and a net loss from discontinued
operations of $1.1 million, or $0.01 per fully diluted common share.

   Second Quarter and Full Year 2006 Earnings Per Share Forecast

   The Company currently estimates that second quarter 2006 fully
diluted earnings per share from continuing operations will be in the
range of $1.26 to $1.31, including estimated stock option expense of
$0.02 per share and a total provision for credit losses of
approximately zero. In addition, the Company expects to record a net
loss from discontinued operations of approximately $0.05 per diluted
common share. Therefore, net income per diluted common share is
expected to be in the range of $1.21 to $1.26.
   For full year 2006, the Company currently estimates that fully
diluted earnings per share from continuing operations will be in the
range of $5.30 to $5.50, including estimated stock option expense of
$0.10 per share and an estimated total provision for credit losses of
$10 million. In addition, the Company expects to record a net loss
from discontinued operations of approximately $0.11 per diluted common
share. Therefore, net income per diluted common share is expected to
be in the range of $5.19 to $5.39.

   Non-GAAP Financial Measures

   This press release contains certain references to financial
measures that exclude a loss on the sale of securities related to the
rebalancing of the Company's securities portfolio or stock option
expense and higher restricted stock expense, which are adjustments
from comparable measures calculated and presented in accordance with
accounting principles generally accepted in the United States of
America (GAAP). These financial measures, as used herein, differ from
financial measures reported under GAAP in that they exclude unusual or
non-recurring charges, losses, credits or gains. This press release
identifies the specific items excluded from the comparable GAAP
financial measure in the calculation of each non-GAAP financial
measure. Because these items and their impact on the Company's
performance are difficult to predict, management believes that
financial presentations excluding the impact of these items provide
useful supplemental information which is important to a proper
understanding of the Company's core business results by investors.
These presentations should not be viewed as a substitute for results
determined in accordance with GAAP, nor are they necessarily
comparable to non-GAAP financial measures presented by other
companies.
