              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                 JUNE 30, 1997
                                  (UNAUDITED)
 
NOTE 1 -- BASIS OF PRESENTATION AND NATURE OF OPERATIONS
 
    The unaudited condensed consolidated financial statements of UnionBanCal
Corporation and subsidiaries (the "Company") have been prepared in accordance
with generally accepted accounting principles ("GAAP") for interim financial
reporting and the instructions to Form 10-Q. Accordingly, they do not include
all of the information and footnote disclosures necessary for complete financial
statements in conformity with GAAP. The preparation of financial statements in
conformity with GAAP 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 financial statements and
the reported amounts of revenue and expense during the reporting period. Actual
results could differ from those estimates. These unaudited condensed
consolidated financial statements should be read in conjunction with the audited
consolidated financial statements included in the Company's Form 10-K for the
year ended December 31, 1996.
 
    In the opinion of management, all adjustments (comprised of normal accruals)
considered necessary for a fair presentation of the Company's interim financial
statements have been included.
 
    Primary and fully diluted earnings per share are computed based on net
income after preferred dividends and parent direct interest in bank subsidiary,
and use the weighted average number of common shares and equivalent common
shares outstanding during the period. Stock options are a common stock
equivalent but, for the periods presented, did not have a dilutive effect and
are, therefore, not included in the Company's earnings per share calculations.
 
NOTE 2 -- RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
 
    In June 1996, Statement of Financial Accounting Standards ("SFAS") No. 125,
"Accounting for Transfers and Servicing of Financial Assets and Extinguishments
of Liabilities" was issued. This Statement establishes standards for when
transfers of financial assets, including those with continuing involvement by
the transferor, should be considered a sale. SFAS No. 125 also establishes
standards for when a liability should be considered extinguished. This statement
is effective for transfers of assets and extinguishments of liabilities after
December 31, 1996. In December 1996, the Financial Accounting Standards Board
("FASB") reconsidered certain provisions of SFAS No. 125 and issued SFAS No.
127, "Deferral of the Effective Date of Certain Provisions of FASB Statement No.
125" to defer for one year the effective date of implementation for transactions
related to repurchase agreements, dollar-roll repurchase agreements, securities
lending and similar transactions. Management determined that the effect of
adoption of SFAS No. 125 on the Company's financial statements was not material
and believes that the effect of adoption of SFAS No. 127 will also not be
material.
 
    In February 1997, the FASB issued SFAS No. 128, "Earnings per Share". This
Statement simplifies the standards for computing earnings per share ("EPS") and
makes them comparable to international EPS standards. SFAS No. 128 replaces the
presentation of primary EPS with a presentation of basic EPS. In addition, all
entities with complex capital structures are required to provide a dual
disclosure of basic and diluted EPS on the face of the income statement and a
reconciliation of the numerator and denominator of the basic EPS computation to
the numerator and denominator of the diluted EPS computation. This Statement
applies to entities with publicly held common stock or potential common stock
and is effective for financial statements issued for periods ending after
December 15, 1997, including interim periods, and requires restatement of all
prior period EPS data presented.

    In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income", which requires that an enterprise report, by major components and as a
single total, the change in its net assets during the period from non-owner
sources; and No. 131, "Disclosures about Segments of an Enterprise and Related
Information", which establishes annual and interim reporting standards for an
enterprise's operating segments and related disclosures about its products,
services, geographic areas, and major customers. Adoption of these statements
will not impact the Company's consolidated financial position, results of
operations or cash flows, and any effect will be limited to the form and content
of its disclosures. Both statements are effective for fiscal years beginning
after December 15, 1997, with earlier application permitted.
 
NOTE 3 -- SUBSEQUENT EVENT
 
    Subsequent to June 30, 1997, the Franchise Tax Board of the State of
California approved tax and interest refunds to settle litigation,
administration and audit disputes covering tax years 1975-1987. The final
agreement is expected to be signed during the third quarter of 1997. It is
estimated that the effect will be to reduce income tax expense and,
correspondingly, to increase net income by approximately $25 million for the
three and nine month periods ending September 30, 1997.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS
 
INTRODUCTION
 
    UnionBanCal Corporation is a San Francisco, California-based bank holding
company with consolidated assets of $30 billion at June 30, 1997. Its primary
banking subsidiary is Union Bank of California, N.A., the third largest
commercial bank in California, and among the 30 largest banks in the United
States. Union Bank of California, N.A., had 237 banking offices in California, 5
banking offices in Oregon and Washington and 18 overseas facilities at June 30,
1997. UnionBanCal Corporation is 81 percent owned by The Bank of
Tokyo-Mitsubishi, Ltd., and 19 percent owned by other shareholders. Union Bank
of California, N.A., is 94 percent owned by UnionBanCal Corporation and 6
percent directly owned by The Bank of Tokyo-Mitsubishi, Ltd.
 
    THIS DOCUMENT MAY CONTAIN FORWARD-LOOKING STATEMENTS THAT ARE SUBJECT TO
RISKS AND UNCERTAINTIES THAT COULD CAUSE ACTUAL RESULTS TO DIFFER MATERIALLY
FROM THOSE INDICATED. FOR A DISCUSSION OF FACTORS THAT COULD CAUSE ACTUAL
RESULTS TO DIFFER, PLEASE SEE THE DISCUSSION CONTAINED HEREIN AND IN THE
COMPANY'S PUBLICLY AVAILABLE SECURITIES AND EXCHANGE COMMISSION FILINGS AND
PRESS RELEASES.
 
    The interim financial information should be read in conjunction with the
Company's Form 10-K for the year ended December 31, 1996. Certain amounts for
prior periods have been reclassified to conform with current financial statement
presentation.
 
MERGER ACCOUNTING
 
    UnionBanCal Corporation was formed from the combination of Union Bank with
BanCal Tri-State Corporation and its banking subsidiary, The Bank of California,
N.A., on April 1, 1996. The merger was effected by the issuance of 18,134,027
shares of Union Bank common stock in exchange for all the outstanding common
shares of BanCal Tri-State Corporation.
 
    The combination was accounted for as a reorganization of entities under
common control (similar to a pooling of interests). Accordingly, all historical
financial information has been restated as if the combination had been in effect
for all periods presented.
 
    To facilitate the discussion of the results of operations, the Consolidated
Financial Highlights on pages 2 and 3 and the Analysis of Earnings on page 13
include certain pro forma earnings disclosures. These presentations supplement
the Condensed Consolidated Statements of Income on page 4 (which are prepared in
accordance with GAAP) with respect to the treatment of merger and integration
expense. Management believes that it is meaningful to review the operating
results trends excluding merger and integration expense and, therefore, has
included information in the Consolidated Financial Highlights and the Analysis
of Earnings which presents earnings before and after income taxes, as well as
certain financial ratios, excluding merger and integration expense.

SUMMARY
 
    Net income in the second quarter of 1997 was $97 million, compared with $44
million in the second quarter of 1996. Net income applicable to common stock was
$88 million, or $1.61 per common share, in the second quarter of 1997, compared
with $39 million, or $0.71 per common share, in the second quarter of 1996. Pro
forma earnings, excluding after-tax merger and integration expense, were $97
million in the second quarter of 1997, an increase of 17 percent from $83
million a year earlier. Pro forma earnings applicable to common stock were $88
million, or $1.61 per common share, compared with $75 million, or $1.37 per
common share, in the second quarter of 1996. Other highlights of the second
quarter of 1997 include:
 
    - Net interest income on a taxable-equivalent basis was $308 million in the
      second quarter of 1997, an $18 million, or 6 percent, increase from the
      comparable period one year earlier, primarily due to a $1.5 billion, or 6
      percent, increase in average earning assets and a 12 percent increase in
      average demand deposits.
 
    - No provision for credit losses was recorded, compared with $10 million in
      the second quarter of 1996, reflecting improvement in the quality of the
      loan portfolio. Net loans charged off in the second quarter of 1997, were
      $21 million, or 0.39% of average loans outstanding, compared with $12
      million, or 0.24% of average loans outstanding, for the second quarter of
      1996.
 
    - Noninterest income was $111 million, an increase of $5 million over the
      second quarter of 1996, due primarily to an increase in service charges on
      deposits of $3 million and an increase in trust fees of $2 million.
 
    - Noninterest expense, excluding merger and integration expense, was $256
      million for the second quarter of 1997, compared with $253 million for the
      second quarter of 1996, an increase of 1 percent. Salaries and employee
      benefits declined $3 million due to staff reductions and occupancy
      declined $1 million due to the closure of banking offices, while all other
      noninterest expense combined increased $7 million or 8 percent. No merger
      and integration expense was recorded in the second quarter of 1997,
      compared with $61 million in the second quarter of 1996.
 
    - The effective tax rate for second quarter 1997 was 41 percent compared
      with 37 percent for the same quarter in 1996, primarily due to a $5
      million tax benefit in 1996 reflecting the settlement of a unitary tax
      issue with the California Franchise Tax Board.
 
    - In the second quarter 1997, the return on average assets increased to
      1.32% from 0.64% a year earlier. The return on average common equity
      increased to 15.16% from 7.26%. Excluding the after-tax effect of merger
      and integration expense, the pro forma return on average assets increased
      to 1.32% from 1.20%, while the pro forma return on average common equity
      increased to 15.16% from 13.95%.
 
    - Total loans at June 30, 1997, increased $1.5 billion, or 7 percent, over
      June 30, 1996, primarily due to growth in the commercial, financial and
      industrial and the commercial mortgage portfolios. At $22.0 billion, total
      loans were 4 percent higher at June 30, 1997 than at March 31, 1997.
 
    - Nonperforming assets declined $52 million, or 23 percent, from June 30,
      1996, to $176 million at June 30, 1997. Nonperforming assets as a percent
      of total assets were 0.58% at June 30, 1997 compared with 0.81% a year
      earlier. Total nonaccrual loans at June 30, 1997 and 1996 were $146
      million and $191 million, respectively. This decrease caused the ratio of
      nonaccrual and renegotiated loans to total loans to drop from 0.94% to
      0.67%.
 
    - The Company's Tier 1 and total risk-based capital ratios were 9.19% and
      11.59% at June 30, 1997, compared with 8.94% and 11.24% at June 30, 1996.
      The second quarter 1997 leverage ratio for the Company was 8.68%, compared
      with 8.33% for the second quarter of 1996. The increase in the capital
      ratios was primarily attributable to additional retained earnings.

SUMMARY (CONTINUED)
 
    Net income in the first half of 1997 was $189 million, including $4 million
of after-tax merger and integration expense recorded in connection with the
April 1, 1996, combination of Union Bank and BanCal Tri-State Corporation. Net
income for the first half of 1996 was $128 million, including $38 million of
after-tax merger and integration expense. Net income applicable to common stock
was $172 million, or $3.15 per common share, in the first half of 1997, compared
with $116 million, or $2.12 per common share, in the first half of 1996. Pro
forma earnings, excluding after-tax merger and integration expense, were $193
million, an increase of 16 percent from a year earlier. Pro forma earnings
applicable to common stock were $176 million, or $3.21 per common share,
compared with $152 million, or $2.78 per common share, in the first half of
1996. Other comparisons of the first half of 1997 with the first half of 1996
are as follows:
 
    - Net interest income on a taxable-equivalent basis was $604 million in the
      first half of 1997, a $16 million, or 3 percent, increase from the
      comparable period one year earlier. Although the net interest margin
      declined 12 basis points to 4.72 percent, largely due to a drop in the
      average domestic loan yield of 17 basis points, net interest income
      increased, primarily due to loan growth of 5 percent and demand deposit
      growth of 11 percent.
 
    - No provision for credit losses was recorded, compared with $20 million in
      the first half of 1996, reflecting improvement in the quality of the loan
      portfolio. Net loans charged off in the first half of 1997 were $22
      million, or 0.21% of average loans outstanding, compared with $30 million,
      or 0.30% of average loans outstanding, in the same period a year earlier.
 
    - Noninterest income was $226 million, an increase of $17 million over the
      first half of 1996, due primarily to a $6 million increase in service
      charges on deposits and an $8 million gain on a real estate joint venture.
 
    - Noninterest expense, excluding merger and integration expense, was $503
      million in the first half of 1997, compared with $505 million in the first
      half of 1996. Personnel-related and occupancy expense decreased by $4
      million each as a result of merger consolidations. In addition, foreclosed
      asset expense declined $3 million. These decreases were mostly offset by
      increases in other noninterest expense categories.
 
    - The effective tax rate for the first half of 1997 was 41%, compared with
      38% for the same period of 1996. The increase was primarily due to a $5
      million tax benefit in 1996 reflecting the settlement of a unitary tax
      issue with the California Franchise Tax Board and to a post-merger
      increase in the effective state tax rate.
 
    - The return on average assets increased to 1.31% from 0.93%. The return on
      average common equity increased to 15.14% from 10.65%. Excluding the
      after-tax effect of merger and integration expense, the pro forma return
      on average assets increased to 1.33% from 1.21%, while the pro forma
      return on average common equity increased to 15.43% from 13.96%. The 12
      basis point increase in pro forma return on average assets was
      attributable to a 16 percent increase in pro forma earnings combined with
      a 5 percent increase in average assets. Similarly, the 147 basis point
      increase in pro forma return on average common equity was due to a 16
      percent increase in pro forma earnings applicable to common stock combined
      with a 5 percent increase in average common equity.

NET INTEREST INCOME (CONTINUED)
 
    Net interest income is interest earned on loans and investments less
interest expense on deposit accounts and borrowings. Primary factors affecting
the level of net interest income include the margin between the yield earned on
interest earning assets and the rate paid on interest bearing liabilities, as
well as the composition of average interest earning assets and average interest
bearing liabilities.
 
    Net interest income on a taxable-equivalent basis was $308 million for the
second quarter of 1997 and $290 million for the second quarter of 1996. This
increase of $18 million, or 6 percent, was primarily attributable to a $1.5
billion, or 6 percent, increase in average earning assets and an $804 million,
or 12 percent, increase in average demand deposits. At the same time, the net
interest margin declined 2 basis points to 4.75%, primarily as a result of a 9
basis point increase in the cost of interest bearing liabilities, which was
largely offset by an increase in the proportion of funding provided by demand
deposits.
 
    Average earning assets were $26.0 billion in the second quarter of 1997,
compared with $24.5 billion in the second quarter of 1996. Most of this increase
was attributable to growth in average loans, which increased $1.2 billion, or 6
percent, while average investment securities were $347 million higher. See
"Loans" for additional commentary on growth in the loan portfolio. The increase
in investment securities reflected interest rate risk management actions to
reduce the Company's exposure to declines in interest rates.
 
    The $1.5 billion, or 6 percent, growth in average earning assets from the
second quarter of 1996 to the second quarter of 1997 was funded primarily by
increases in demand deposits and interest bearing core deposits. Increases in
these categories were: demand deposits $804 million, or 12 percent; interest
bearing domestic deposits $357 million, or 7 percent; and savings and consumer
time deposits $139 million, or 5 percent. The average proportion of funding
provided by noninterest bearing and interest bearing core deposits (excluding
large time) increased from 65 percent in the second quarter of 1996 to 66
percent in the same period of 1997.
 
    For the first half of 1997, net interest income on a taxable-equivalent
basis was $604 million, compared with $588 million in the comparable period one
year earlier. The increase of $16 million, or 3 percent, was primarily
attributable to a $1.3 billion, or 5 percent, increase in average earning assets
and a $744 million, or 11 percent, increase in average demand deposits.
Partially offsetting the positive impact of the growth in earning assets and
demand deposits on net interest income was a 12 basis point decline in the net
interest margin to 4.72%. The decline in the net interest margin resulted from
both an increase in the cost of lower cost sources of funds and a decrease in
the average yield on domestic loans. The cost of interest bearing core deposits
(excluding large time) increased by 8 basis points, while the yield on domestic
loans dropped by 17 basis points. The negative impact on the net interest margin
of these two factors was partially offset by an increase in the proportion of
funding provided by demand deposits.

    In the second quarter of 1997, noninterest income was $111 million, compared
with $106 million for the same period in 1996. This increase of $5 million
included a $3 million increase in service charges on deposits, arising from an
increase in the volume of non-credit services, and a $2 million increase in
trust fees, primarily due to growth in the Company's proprietary mutual funds.
Increases of approximately $1 million each in credit card merchant fees,
merchant banking fees, investment services fees, and foreign exchange fees were
offset by a $3 million decrease in net gains on sales of investment securities.
 
    For the six months ended June 30, 1997, noninterest income increased to $226
million from $208 million for the same period in 1996. This increase of $18
million was primarily due to an $8 million gain from a real estate joint venture
(included in "Other" in the first quarter of 1997), a $6 million increase in
service charges on deposits, a $4 million increase in trust fees and a $3
million increase in credit card merchant fees, offset by a $3 million decrease
in net gains on sales of investment securities.

    Noninterest expense, excluding merger and integration expense, was $256
million for the second quarter of 1997, compared with $253 million for the
second quarter of 1996, an increase of $3 million, or 1 percent.
Personnel-related expense decreased $3 million, or 2 percent, due to a 6 percent
decline in full-time equivalent employees. In addition, occupancy expense
decreased $1 million due to the consolidation of administrative functions and
the closure of banking offices. Offsetting these reductions was an increase of
$7 million, or 8 percent, in all other noninterest expense combined. No merger
and integration expense was recorded in the second quarter of 1997, compared
with $61 million in the same quarter in 1996.
 
    For the six months ended June 30, 1997, noninterest expense, excluding
merger and integration expense of $6 million, was $503 million, compared with
$505 million, excluding merger and integration expense of $61 million, for the
first six months of 1996. This decrease of $2 million, or less than 1 percent,
resulted principally from a $4 million decrease in personnel-related expense,
primarily due to a 5 percent decline in full-time equivalent employees, a $4
million reduction in occupancy expense, and a $3 million decline in foreclosed
asset expense. These decreases were largely offset by increases in other
noninterest expense, primarily communications, credit card processing and data
processing expense.

MERGER AND INTEGRATION EXPENSE
 
    In the second quarter of 1997, no merger and integration expense was
recorded, compared with $6 million in the first quarter of 1997 and $61 million
in the second quarter of 1996. The combination of Union Bank and BanCal
Tri-State Corporation on April 1, 1996, resulted in the recording of a total of
$124 million in merger and integration expense.
 
    The table that follows presents merger and integration expense provisions in
1996 and the first half of 1997, the cash and noncash utilization of those
expense provisions during the periods, and the resulting liability balances as
of June 30, 1997, and December 31, 1996.

INCOME TAX EXPENSE
 
    The effective tax rates for the second quarter of 1997 and 1996 were 40.5
percent and 36.6 percent, respectively. The increase was primarily attributable
to a $5 million benefit recognized in the second quarter of 1996 from a
settlement with the California Franchise Tax Board for 1985 and 1986.
 
    The effective tax rates for the six months ended June 30, 1997 and 1996,
were 40.5 percent and 38.2 percent, respectively. The increase in the effective
tax rate was primarily attributable to an increase in the effective state tax
rates as a result of the combination of Union Bank with BanCal Tri-State
Corporation and of their parents, The Bank of Tokyo, Ltd. and The Mitsubishi
Bank, Limited, on April 1, 1996, and to the settlement with the California
Franchise Tax Board in the second quarter of 1996.

    The Company's lending activities are predominantly domestic, with such loans
comprising approximately 94 percent of the portfolio at June 30, 1997. Total
loans at June 30, 1997, were $22.0 billion, an increase of $1.5 billion, or 7
percent, from June 30, 1996. The increase was primarily attributable to growth
in the commercial, financial and industrial loan portfolio, which increased $946
million from June 30, 1996, and to the commercial real estate mortgage loan
portfolio, which increased $503 million.
 
    Commercial, financial and industrial loans represent the largest category in
the loan portfolio. These loans are principally to major corporations, middle
market businesses, and small businesses, with no industry concentration
exceeding ten percent of the total. At June 30, 1997 and 1996, the commercial,
financial and industrial loan portfolio was $10.4 billion, or 47 percent of
total loans, and $9.4 billion, or 46 percent of total loans, respectively.
During the second quarter of 1997, commercial, financial and industrial loans
increased $709 million, or 7 percent. The increase was primarily attributable to
loans to large corporations in industries in which the bank has specialized
lending expertise.
 
    The construction loan portfolio totaled $319 million, or 1 percent of total
loans, at June 30, 1997, compared with $366 million, or 2 percent of total
loans, at June 30, 1996.
 
    Mortgage loans were $5.8 billion, or 26 percent of total loans, at June 30,
1997, and $5.3 billion, or 26 percent of total loans, at June 30, 1996. The
mortgage loan portfolio consists of loans on commercial and industrial projects
and loans secured by one to four family residential properties, primarily in
California. Commercial mortgages increased $503 million from June 30, 1996 to
June 30, 1997, primarily due to an increase in mini perm loans ranging from $1
million to $10 million in size.
 
    Consumer loans totaled $3.4 billion, or 15 percent of total loans, at June
30, 1997, compared with $3.4 billion, or 17 percent of total loans, at June 30,
1996. This portfolio is primarily comprised of installment loans and home equity
loans.
 
    Lease financing totaled $858 million, or 4 percent of total loans, at June
30, 1997, compared with $831 million, or 4 percent of total loans, at June 30,
1996.
 
    Loans originated in foreign branches totaled $1.2 billion, or 6 percent of
total loans, at June 30, 1997, and $1.1 billion, or 5 percent of total loans, at
June 30, 1996.

ALLOWANCE FOR CREDIT LOSSES
 
    The allowance for credit losses is maintained at a level considered
appropriate by management and is based on an ongoing assessment of risk in the
credit and lease portfolio, including commitments to provide financing. The
allowance is increased by the provision for credit losses, which is charged
against current period operating results, and is decreased by the amount of net
loans charged off during the period. In evaluating the adequacy of the allowance
for credit losses, management incorporates such factors as collateral value,
portfolio composition and concentration, and trends in local and national
economic conditions and the related impact on the financial strength of the
Company's borrowers. While the allowance is segmented by broad portfolio
categories to analyze its adequacy, the allowance is general in nature and is
available for the portfolio in its entirety. Although management believes that
the allowance for credit losses is adequate, without any provision for credit
losses in the second quarter of 1997, future provisions will be subject to
continuing evaluation of risk in the credit and lease portfolio.
 
    The table below sets forth a reconciliation of changes in the allowance for
credit losses.

ALLOWANCE FOR CREDIT LOSSES (CONTINUED)
 
    At June 30, 1997, the Company's allowance for credit losses was $502
million, or 2.29 percent of total loans, and 344 percent of total nonaccrual
loans, compared with an allowance for credit losses at June 30, 1996, of $545
million, or 2.66 percent of total loans, and 285 percent of total nonaccrual
loans.
 
    During the second quarter of 1997, the Company recorded no provision for
credit losses compared with a provision of $10 million in the second quarter of
1996. Similarly, there was no provision for credit losses in the first quarter
of 1997, compared to a provision of $10 million in the first quarter of 1996.
This resulted from management's regular quarterly assessment of overall credit
quality and economic conditions in relation to the level of the allowance for
credit losses. Future quarterly provisions will be subject to the same
evaluation process.
 
    During the second quarter of 1997, net loans charged off were $21 million,
compared with $12 million in the second quarter of 1996. Net loans charged off
as a percentage of average total loans for the second quarter of 1997 increased
to 0.39%, compared with 0.24% for the same quarter last year. These increases
were primarily attributable to a $6 million increase in commercial loans charged
off. In addition, there were $8 million in recoveries during the second quarter
of 1997 compared with $11 million in recoveries for the same period in 1996.
 
    The Company evaluates its loan portfolio for impairment as defined by
Statement of Financial Accounting Standards No. 114, as amended. At June 30,
1997, total impaired loans were $145 million, and the associated impairment
allowance was $10 million, compared with total impaired loans of $158 million
and an associated impairment allowance of $11 million, at June 30, 1996.

NONPERFORMING ASSETS (CONTINUED)
    At June 30, 1997, nonperforming assets totaled $176 million, a decrease of
$52 million, or 23 percent, from a year earlier. The decrease was primarily the
result of reductions of $18 million in nonaccrual commercial mortgage loans, $15
million in nonaccrual residential mortgage loans, $7 million in nonaccrual
commercial, financial and industrial loans, and $6 million in foreclosed assets.
The decrease in nonaccrual residential mortgage loans is a permanent reduction,
due to a change in policy in 1997. Since December 31, 1996, nonperforming assets
have increased by $19 million, primarily due to the addition of two nonaccrual
commercial, financial and industrial loans totaling $36 million.
 
    Nonaccrual and renegotiated loans as a percentage of total loans were 0.67%
at June 30, 1997, compared with 0.94% at June 30, 1996. Nonperforming assets as
a percentage of total loans and foreclosed assets were 0.80% at June 30, 1997,
compared with 1.11% at June 30, 1996.

LIQUIDITY
 
    Liquidity refers to the Company's ability to adjust its future cash flows to
meet the needs of depositors and borrowers and to fund operations on a timely
and cost-effective basis. The Company's liquidity management draws upon the
strengths of its extensive retail and commercial market business franchise,
coupled with its ability to obtain funds for various terms in a variety of
domestic and international money markets.
 
    Core deposits provide the Company with a sizable source of relatively stable
and low-cost funds. In the second quarter of 1997, lower cost sources of funds,
which include demand deposits and interest bearing core deposits, funded 66
percent of average earning assets. Most of the remaining funding was provided by
short-term borrowing in the form of negotiable certificates of deposit, foreign
deposits, federal funds purchased and securities sold under repurchase
agreements, commercial paper, and other borrowings.

</TABLE>
 
- ------------------------------
 
(1)  Tier 1 capital divided by quarterly average assets.
 
    The Company and the Company's subsidiary bank, Union Bank of California,
N.A. (the "Bank") are subject to various regulations issued by Federal banking
agencies, including minimum capital requirements. The Company and the Bank are
required to maintain minimum ratios of total and Tier 1 capital to risk-weighted
assets and of Tier 1 capital to average assets (the "leverage ratio").
 
    Compared with one year earlier, the Company's Tier 1 risk-based capital
ratio at June 30, 1997, increased 25 basis points to 9.19%, the total risk-based
capital ratio increased 35 basis points to 11.59%, and the leverage ratio
increased 35 basis points to 8.68%. The increase in the capital ratios was due
to retained earnings growing faster than both risk-weighted assets and average
assets. Additionally, the increase in the total capital ratio was partially
attributable to the issuance of $200 million in long-term subordinated debt in
June 1997, partly offset by the redemption of $100 million of subordinated debt
in the first quarter of 1997.
 
    In June 1997, the Company announced that it will redeem $135 million of
preferred stock in the third quarter of 1997. A reduction of $135 million in
Tier 1 capital as of June 30, 1997, would have resulted in a decrease in the
Tier 1 and total capital ratios of 50 basis points, and a decrease in the
leverage ratio of 46 basis points.
 
    As of June 30, 1997, management believes the capital ratios of the Bank met
all regulatory minimums of a well-capitalized bank. Since the preferred stock to
be redeemed in the third quarter of 1997 was issued by UnionBanCal Corporation's
holding company, the redemption will have no impact on the capital ratios of the
Bank.
