                    Quarter 2006 Earnings Per Share of $1.21


    SAN FRANCISCO--(BUSINESS WIRE)--Oct. 19, 2006--UnionBanCal
Corporation (NYSE:UB):



Third Quarter 2006 Highlights:

- -- Strong year-over-year organic loan growth
    -- Average total loans up 12 percent
    -- Average commercial loans up 16 percent
    -- Average residential mortgage loans up 11 percent
- -- Annualized average all-in cost of funds of 2.11 percent
- -- Average noninterest bearing deposits comprised 42 percent of
   average total deposits
- -- Nonperforming assets were 0.09 percent of total assets at
   quarter-end


    UnionBanCal Corporation (NYSE:UB) today reported third quarter
2006 net income of $170.7 million, or $1.20 per diluted common share,
compared with $1.26 per diluted common share a year earlier. Income
from continuing operations was $171.9 million, or $1.21 per diluted
common share, compared with $1.36 per diluted common share a year
earlier. Income from continuing operations for third quarter 2005
included a $10 million, or $0.04 per diluted common share, negative
loan loss provision associated with the sale of the international
correspondent banking business and $9 million, or $0.06 per diluted
common share, in income tax adjustments. Adjusting for these two
items, income from continuing operations for third quarter 2005 was
$1.26 per diluted common share.

    For the first nine months of 2006, net income was $527 million, or
$3.65 per diluted common share, compared with $3.74 per diluted common
share for the first nine months of 2005. Income from continuing
operations was $536 million, or $3.71 per diluted common share,
compared with $3.84 per diluted common share for the first nine months
of 2005. Income from continuing operations for the first nine months
of 2006 included stock option expense of $17.3 million, or $0.07 per
diluted common share, versus none in the comparable period in 2005.

    "Third quarter results were generally in line with our
expectations," stated Takashi Morimura, President and Chief Executive
Officer. "We continued to generate strong loan growth, and credit
quality continued to be excellent. At the same time, we continued to
be adversely impacted by unfavorable deposit mix and deposit pricing
trends."

    Added Chief Operating Officer Philip Flynn, "We are pleased with
the balanced growth we are generating in the loan portfolio. However,
excellent lending results for the quarter were offset by the effects
of a very competitive deposit market. Short-term profitability is
being negatively affected as customers shift deposit balances to
higher rate products, and as deposit rates continue to increase faster
than loan yields. Despite these current challenges, our deposit
franchise remains healthy and profitable, and well-positioned for the
long run. We continue to be among the industry leaders in noninterest
bearing deposit mix, core deposit mix, average all-in cost of funds,
and net interest margin. We believe our balanced business model will
continue to produce solid long-term results."

    Summary of Third Quarter Results from Continuing Operations

    For third quarter 2006, income from continuing operations was
$171.9 million, or $1.21 per diluted common share, compared with $1.36
per diluted common share a year earlier. Total revenue was flat,
compared with third quarter 2005. A 2.4 percent increase in
noninterest income was offset by a 1 percent decrease in net interest
income. The decrease in net interest income was primarily due to a
deposit mix shift reflecting customer decisions to shift balances from
noninterest bearing and low-cost deposits into higher-cost deposits.
The unfavorable deposit mix change offset strong loan growth. The
total provision for credit losses was zero, compared with negative $15
million in third quarter last year. Of the negative $15 million total
provision for credit losses recognized in third quarter 2005, negative
$10 million was related to the sale of the international correspondent
banking business, now a discontinued operation. For third quarter
2006, noninterest expense was up 5 percent from the same quarter a
year ago. Adjusting for the impact of stock option expense, which
commenced January 1, 2006, and a $3.2 million decline in foreclosed
asset income, noninterest expense increased 3 percent. The effective
tax rate was higher in third quarter 2006 due to $9 million in income
tax adjustments recorded in third quarter 2005.

    Adjusting for the negative $10 million provision related to the
discontinued operation, $3.4 million in foreclosed asset income, and
the $9 million of tax adjustments, income from continuing operations
was $1.25 per diluted common share for third quarter 2005. Adjusting
for the $6 million of stock option expense and $0.2 million in
foreclosed asset income recorded in third quarter this year, income
from continuing operations was $1.23 per diluted common share for
third quarter 2006. Therefore, on an adjusted basis, income from
continuing operations for third quarter 2006 declined 2 cents, or 1.6
percent, compared with third quarter 2005.

    Third Quarter Total Revenue From Continuing Operations

    For third quarter 2006, total revenue (taxable-equivalent net
interest income plus noninterest income) was $678 million, flat
compared with third quarter 2005. Net interest income decreased 1.0
percent, and noninterest income increased 2.4 percent. Compared with
second quarter 2006, total revenue decreased 1.5 percent, with net
interest income decreasing 1.8 percent and noninterest income
decreasing 0.9 percent.

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

    Net interest income was $461 million in third quarter 2006, down
$5 million, or 1.0 percent, from the same quarter a year ago,
primarily due to a deposit mix shift from noninterest bearing and
low-cost deposits into higher-cost deposits, partially offset by solid
growth in loans and higher yields on earning assets.

    Average earning assets increased $2.5 billion, or 5.7 percent,
compared to last year, primarily due to a $3.8 billion, or 11.8
percent, increase in average loans. Average commercial loans increased
$1.8 billion, or 15.6 percent; average residential mortgages increased
$1.2 billion, or 11.2 percent; and average construction loans
increased $0.7 billion, or 53.3 percent. The increase in construction
loans is primarily related to income properties, where business
fundamentals continue to be very healthy. Average securities declined
$1.4 billion, or 14.2 percent.

    Compared to third quarter 2005, average interest bearing deposits
increased $2.7 billion, or 12.8 percent, while average noninterest
bearing deposits decreased $2.4 billion, or 12.4 percent. The decline
in noninterest bearing deposits was primarily due to a $1.1 billion,
or 8.2 percent, decrease in average other commercial noninterest
bearing deposits and a $1.0 billion, or 29.8 percent, decrease in
average title and escrow deposits. Average other commercial
noninterest bearing deposits declined primarily due to changes in
customer behavior in response to rising short-term interest rates, and
average title and escrow deposits decreased due to lower residential
real estate activity. Average consumer noninterest bearing deposits
decreased $311 million, or 9.6 percent.

    Average noninterest bearing deposits represented 41.9 percent of
average total deposits in third quarter 2006. The annualized average
all-in cost of funds was 2.11 percent, reflecting the Company's strong
average core deposit-to-loan ratio of 94 percent and the high
proportion of noninterest bearing deposits to total deposits.

    The average yield on earning assets of $45.9 billion was 6.06
percent, up 85 basis points over third quarter 2005, with the average
loan yield increasing 66 basis points. The average rate on interest
bearing liabilities of $27.7 billion was 3.41 percent, up 165 basis
points compared with third quarter 2005, reflecting higher short-term
interest rates, an unfavorable change in deposit mix, and heightened
competition for deposits. Average interest bearing deposits were $23.6
billion and the weighted average rate was 3.07 percent. Average core
deposits funded 73.9 percent of average earning assets in the third
quarter. The net interest margin in third quarter 2006 was 4.00
percent, compared with 4.27 percent in third quarter 2005.

    On a sequential quarter basis, net interest income decreased $8
million, or 1.8 percent. Average loans increased $0.8 billion, or 2.3
percent. Average commercial loans increased $282 million, or 2.2
percent; average residential mortgages increased $238 million, or 2.0
percent; and average construction loans increased $267 million, or
15.5 percent. Average noninterest bearing deposits decreased $553
million, or 3.2 percent, with commercial noninterest bearing deposits
decreasing $316 million, partially due to a $59 million decrease in
title and escrow deposits, and consumer noninterest bearing deposits
decreasing $237 million, or 7.5 percent. The average yield on earning
assets increased 11 basis points and the average rate on interest
bearing liabilities increased 46 basis points. The net interest margin
decreased 23 basis points to 4.00 percent.

    Third Quarter Noninterest Income From Continuing Operations

    In third quarter 2006, noninterest income was $217 million, up $5
million, or 2.4 percent, from the same quarter a year ago. Service
charges on deposit accounts decreased $6 million, or 6.8 percent,
primarily due to lower account analysis fees, stemming from an
increase in the earnings credit rate on deposit balances and lower
noninterest bearing deposit balances. Trust and investment management
fees increased $4 million, or 9.3 percent, primarily due to an
increase in trust assets.

    Compared with the preceding quarter, third quarter 2006
noninterest income decreased $2 million, or 0.9 percent, primarily due
to declines in service charges on deposit accounts.

    Third Quarter Noninterest Expense From Continuing Operations

    Noninterest expense for third quarter 2006 was $417 million, an
increase of $20 million, or 5.1 percent, over third quarter 2005.
Salaries and employee benefits expense increased $8.5 million, or 3.6
percent, primarily due to higher stock option expense, annual merit
increases and higher employee count, partially offset by lower
incentive and bonus expense and lower accruals for workers'
compensation expense. Stock option expense was $5.7 million, compared
with none in third quarter 2005. Outside services expense increased
$3.4 million, or 11.8 percent, primarily due to higher trust
administration expenses. Advertising and public relations expense
increased $2.6 million, or 28.7 percent, primarily due to increased
advertising and marketing activity in response to the competitive
deposit market. Foreclosed asset income was $3.2 million lower than in
prior year. There was no provision for off-balance sheet commitments
in third quarter 2006 or third quarter 2005.

    Excluding the effect of stock option expense and lower foreclosed
asset income, noninterest expense increased $11.4 million, or 2.9
percent, compared with prior year.

    Compared with second quarter 2006, noninterest expense increased
$4 million, or 1.0 percent. Salaries and employee benefits expense
decreased $4.0 million, or 1.6 percent, primarily due to a $4.4
million decrease in incentive and bonus expense in the third quarter.
Professional services expense decreased $4.9 million, or 28.6 percent,
partially due to lower compliance-related expense. Foreclosed asset
income was $7.6 million lower than in second quarter 2006. There was
no provision for off-balance sheet commitments, compared with negative
$4 million in second quarter 2006.

    Excluding the $7.6 million decrease in foreclosed asset income and
the $4 million negative off-balance sheet commitment provision in
second quarter, noninterest expense declined $7.6 million, or 1.8
percent, on a sequential quarter basis.

    Income Tax Expense From Continuing Operations

    The effective tax rate for third quarter 2006 was 33.6 percent,
compared with an effective tax rate of 31.7 percent for third quarter
2005. Third quarter 2005 income tax expense was reduced by
approximately $9 million, primarily as a result of the adjustment of
California state taxes to reflect tax returns filed on the worldwide
unitary method, and the recognition of California Enterprise Zone tax
credits for which the Company qualified during the quarter.

    Year-to-Date Results From Continuing Operations

    Total revenue was $2.1 billion in the first nine months of 2006,
an increase of $67 million, or 3.4 percent, compared with the same
period of 2005. Net interest income increased 2.5 percent, and
noninterest income increased 5.3 percent.

    Net interest income was $1.4 billion in the first nine months of
2006, a $34 million, or 2.5 percent, increase from prior year,
primarily due to growth in earning assets. Average loans increased
$4.3 billion, or 13.8 percent, while the net interest margin decreased
8 basis points, to 4.19 percent. Average total deposits increased $0.4
billion, or 1.1 percent, primarily due to a $1.9 billion increase in
average interest bearing deposits, offset by a $1.4 billion, or 7.7
percent, decrease in average noninterest bearing deposits. This
deposit mix shift was due to changes in customer behavior in response
to rising short-term interest rates.

    Noninterest income in the first nine months of 2006 was $654
million, an increase of $33 million, or 5.3 percent, over the same
period in 2005. Service charges on deposit accounts decreased $1
million, or 0.5 percent. Trust and investment management fees
increased $19 million, or 15.0 percent, primarily due to growth in
trust assets and a refinement in accrual methodology implemented in
first quarter 2006. Insurance commissions decreased $5 million, or 7.8
percent, partially due to lower contingent commissions. Merchant
banking fees decreased $7 million, or 20.6 percent, primarily due to a
lower volume of transactions completed in 2006. Securities gains
(losses), net, were $1.8 million, compared with $(13.3) million in the
same period in 2005.

    For the first nine months of 2006, noninterest expense increased
$67 million, or 5.6 percent, over the first nine months of 2005.
Salaries and employee benefits expense increased $44 million, or 6.3
percent, primarily due to $17.3 million in stock option expense in the
current year, merit increases, higher employee count, and higher
contract labor expense, reflecting compliance-related initiatives.
Outside services expense increased $15 million, or 19.6 percent,
primarily due to higher trust administration expenses and higher cost
of services related to title and escrow balances, stemming from a
higher earnings credit rate in the first nine months of 2006.
Professional services expense increased $8 million, or 21.1 percent,
primarily due to higher compliance-related expense. The provision for
off-balance sheet commitments was negative $7 million, compared with
negative $1 million in the first nine months of 2005.

    Credit Quality

    Nonperforming assets at September 30, 2006, were $48 million, or
0.09 percent of total assets. This compares with $36 million, or 0.07
percent of total assets, at June 30, 2006, and $38 million, or 0.07
percent of total assets, at September 30, 2005.

    In third quarter 2006, the total provision for credit losses was
zero. The total provision for credit losses was negative $5 million in
second quarter 2006 and negative $15 million in third quarter 2005. In
third quarter 2006, net charge-offs were $2 million, compared with net
charge-offs of $10 million in second quarter 2006, and net charge-offs
of $16 million in third quarter 2005.

    At September 30, 2006, the allowance for credit losses as a
percent of total loans and as a percent of nonaccrual loans was 1.14
percent and 850 percent, respectively. These ratios were 1.17 percent
and 1130 percent, respectively, at June 30, 2006, and 1.39 percent and
1272 percent, respectively, at September 30, 2005.

    Balance Sheet and Capital Ratios

    At September 30, 2006, the Company had total assets of $52
billion. Total loans were $35.7 billion and total deposits were $41.8
billion, resulting in a period-end deposit-to-loan ratio of 117
percent. Core deposits totaled $34.6 billion at quarter-end,
representing 97 percent of total loans. At period-end, total
stockholders' equity was $4.7 billion, the tangible equity ratio was
8.09 percent, and the ratio of tangible common equity to risk-weighted
assets was 8.50 percent. Book value per share at September 30, 2006,
was $33.17, up 10.3 percent from a year earlier. The Company's Tier I
and total risk-based capital ratios at period-end were 8.69 percent
and 11.75 percent, respectively.

    Stock Repurchases

    During third quarter 2006, the Company repurchased 2.3 million
shares of common stock at a total price of $143 million, or an average
of $61.04 per repurchased share. For the first nine months of 2006,
the Company repurchased 5.3 million shares of common stock at a total
price of $344 million, or an average of $65.29 per repurchased share.
At September 30, 2006, the Company had remaining repurchase authority
of $259 million.

    Common shares outstanding at September 30, 2006, were 140.3
million, a decrease of 4.3 million shares, or 2.9 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 to Wachovia Bank, N.A. 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 4) and the
average net assets or liabilities of the discontinued operations are
reflected in the analysis of net interest margin (see Exhibits 6, 7
and 8).

    In the third quarter of 2006, the Company recorded a net loss from
discontinued operations of $1.2 million, or $0.01 per diluted common
share.

    Fourth Quarter 2006 Earnings Per Share Forecast

    The Company currently estimates that fourth quarter 2006 fully
diluted earnings per share from continuing operations will be in the
range of $1.03 to $1.08, including estimated stock option expense of
$0.02 per share and a total provision for credit losses of $5 million,
or $0.02 per share. The Company currently estimates income from
discontinued operations of $0.01 per fully diluted share in the fourth
quarter of 2006. Therefore, net income per diluted common share is
expected to be in the range of $1.04 to $1.09.

    Non-GAAP Financial Measures

    This press release contains certain references to financial
measures identified as being stated on an "adjusted basis" or that
adjust for or exclude stock option expense, foreclosed asset income,
negative off-balance sheet commitment provision, negative loan loss

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.

- ----------------------------------------------------------------------
(1) In September 2005, Union Bank of California, N.A. committed to a
 plan for disposal of its international correspondent banking
 business. All periods presented reflect the discontinued operations.
(2) Taxable-equivalent basis.
(3) Dividends per share reflect dividends declared on UnionBanCal
 Corporation's common stock outstanding as of the declaration date.
(4) End of period total assets and assets used in calculating these
 ratios include those of discontinued operations.
(5) Average balances used to calculate our financial ratios are based
 on continuing operations data only, unless otherwise indicated.
(6) Annualized.
(7) The efficiency ratio is noninterest expense, excluding foreclosed
 asset expense (income) and the (reversal of) provision for losses on
 off-balance sheet commitments, as a percentage of net interest income
 (taxable-equivalent basis) and noninterest income, and is calculated
 for continuing operations only.
(8) Estimated as of September 30, 2006. The regulatory capital and
 leverage ratios were not restated and therefore include discontinued
 operations.
(9) The allowance for credit losses ratios include the allowances for
 loan losses and losses on off-balance sheet commitments. These ratios
 relate to continuing operations only.
(10) Yields and interest income are presented on a taxable-equivalent
 basis using the federal statutory tax rate of 35 percent.
(11) Average balances on loans outstanding include all nonperforming
 loans. The amortized portion of net loan origination fees (costs)
is included in interest income on loans, representing an adjustment to
 the yield.
(12) Net funding allocated from (to) discontinued operations
 represents the shortage (excess) of assets over liabilities of
 discontinued operations. The expense (earning) on funds allocated
 from (to) discontinued operations is calculated by taking the net
 balance and applying an earnings rate or a cost of funds equivalent
 to the corresponding period's Federal funds purchased rate.
