ITEM 1. BUSINESS
 
GENERAL
 
    UnionBanCal Corporation (UNBC) is a commercial bank holding company
incorporated in the State of California in 1952 and is among the oldest banks on
the West Coast, having roots as far back as 1864. UNBC was formed as a result of
the combination of Union Bank with BanCal Tri-State Corporation on April 1,
1996. The combination was effected by the issuance of 54.4 million shares of
Union Bank common stock in exchange for all the outstanding shares of BanCal
Tri-State Corporation.
 
    On November 18, 1998, the Company's Board of Directors approved the
declaration of a 3-for-1 stock split effective for shareholders of record on
December 7, 1998. Accordingly, all historical financial information has been
restated as if the stock split had been in effect for all periods presented.
 
    On August 10, 1998, UNBC and its consolidated subsidiaries (the Company)
exchanged 10.2 million shares of its common stock for 7.2 million shares of
Union Bank of California, N.A. (the Bank) common stock owned directly by the
Bank of Tokyo-Mitsubishi, Ltd. (BTM). This share exchange provides the Company
with a 100 percent ownership interest in the Bank. In addition, it increases
BTM's ownership percentage of the Company to 82 percent from 81 percent.
 
    The exchange of shares was accounted for as a reorganization of entities
under common control. Accordingly, amounts previously reported as Parent Direct
Interest in Bank Subsidiary, including the proportionate share of net income,
dividends, and other comprehensive income have been reclassified to combine them
with the corresponding amounts attributable to the Company's common shareholders
for all periods presented.
 
    At December 31, 1997, the Company was the third largest bank holding company
in California and among the thirty largest in the United States, based on total
assets of $30.6 billion. UNBC is 82 percent owned by BTM and 18 percent owned by
other shareholders. UNBC's principal subsidiary, the Bank, is wholly owned by
UNBC.
 
    The Company provides a wide range of financial services to consumers, small
businesses, middle market companies and major corporations, primarily in
California, Oregon, and Washington, but nationally and internationally as well.

    Customized credit products and financial services are provided to major

of a short-term nature to commercial banks, agencies, and domestic and foreign

SUBSIDIARIES
 
    UNBC has eleven active nonbank subsidiaries that provide various types of
services to it and its customers. Bankers Commercial Corporation, UNBC Leasing,
Inc. and UnionBanCal Leasing Corporation engage in equipment leasing and other
lease related financing. Cal First Properties, Inc. holds and manages various

1958. UnionBanCal Commercial Funding Corporation sells commercial paper and
invests the proceeds in eurodollar placements with the Bank. UnionBanCal
Equities, Inc. invests in equity securities of other companies. Mills-Ralston,

Bank's international correspondent banking business.
 
EMPLOYEES
 
    At December 31, 1997, the Company had 9,753 full-time-equivalent employees.
 
COMPETITION
 
    Banking is a highly competitive business. The Company competes actively for
loan, deposit, and other financial services business in California, Oregon, and
Washington, as well as nationally and internationally.
 
                                       3
<PAGE>
The Company's competitors include a large number of state and national banks and
major foreign-affiliated or foreign banks, as well as many financial and
nonfinancial firms which offer services similar to those offered by the Company
or its subsidiaries.
 
    The Company believes that continued emphasis on enhanced services and
distribution systems, an expanded customer base, increased productivity and
strong credit quality, together with an established capital base, will position
it to meet the challenges provided by this competition.
 
MONETARY POLICY
 
    The operations of bank holding companies and their subsidiaries are affected
by the credit and monetary policies of the Federal Reserve Board (FRB). The FRB
influences financial performance through its management of the discount rate,
the money supply, and reserve requirements on bank deposits. Monetary policies
of the FRB have had and will continue to have a significant effect on the
operating results of financial institutions, including the Company.
 
SUPERVISION AND REGULATION
 
    The Company is subject to regulation under the Bank Holding Company Act of
1956, as amended (BHCA), which subjects it to requirements for filing reports
with the Board of Governors of the Federal Reserve System and for undergoing
regular inspections by the Federal Reserve Bank of San Francisco. Generally, the
BHCA restricts any investment that the Company may make to no more than 5% of
the voting shares of any non-banking entity, and the Company may not acquire
more than 5% of the voting shares of any domestic bank without the prior
approval of the bank regulatory authorities. The Company's activities are
limited, with some exceptions, to banking, the business of managing or
controlling banks, and activities which the regulatory authorities deem to be so
closely related to banking as to be a "proper incident thereto."
 
    The Bank and most of its subsidiaries are regulated by the Office of the
Comptroller of the Currency (OCC). The Company's subsidiaries are also subject
to extensive regulation, supervision and examination by various federal and
state regulatory agencies. In addition, the Bank and its subsidiaries are
subject to certain restrictions under the Federal Reserve Act, including
restrictions on affiliate transactions. Dividends payable by the Bank to the
Company are subject to a formula imposed by the OCC unless express approval is
given to deviate from the formula. For more information regarding restrictions
on loans and dividends by the Bank to its affiliates and on transactions with
affiliates, see Notes 15 and 20 to the Consolidated Financial Statements
included in this Form 10-K/A.
 
    The Federal Deposit Insurance Corporation Improvement Act of 1991 (FDICIA)
imposed stricter capital requirements on banks. FDICIA requires federal bank
regulatory authorities to take "prompt corrective action" in dealing with
inadequately capitalized banks. FDICIA established five tiers of capital
measurement ranging from "well capitalized" to "critically undercapitalized". It
is the Company's policy to maintain risk-based capital ratios for both the
Company and the Bank at or above the required minimum capital adequacy levels.
At December 31, 1997, management believes the Bank met the requirements of a
"well capitalized" institution.
 
    Furthermore, the activities of UBOCIS are subject to the rules and
regulations promulgated by the Securities and Exchange Commission and the NASD,
as well as other securities regulators at the state level.
 
    There are additional requirements and restrictions in the laws of the United
States and the states of California, Oregon and Washington, as well as other
states in which the Bank and its subsidiaries may conduct operations which may
include restrictions on the amount of loans and the nature and amount of
investments, as well as activities as an underwriter of securities, the opening
and closing of branches and the acquisition of other financial institutions.
 
                                       4
<PAGE>
    The activities of the Bank in the international arena may be subject to the
laws and regulations of the jurisdiction where business is being conducted which
may change from time to time and affect the business opportunities and
competitiveness of the Bank in these jurisdictions. Furthermore, due to the
controlling ownership of the Company by BTM, regulatory requirements adopted or
enforced by the Government of Japan may have an effect on the activities and
investments of the Company and the Bank in the future.
 
    The trend followed in recent years by the United States Congress has been to
make major legislative changes which, in turn, lead to major regulatory changes,
which affect the Company, the Bank and its subsidiaries, as well as the
financial services industry in general. Such changes can be expected to occur in
the future. Generally, the effect of such changes has been to increase
competition and narrow the functional distinctions among different types of
financial institutions. In some cases, these changes create opportunities for
the Company and the Bank, as well as the financial services industry, to compete
in financial markets on a more general basis with less regulation. However,
these changes also lead to new and major competitors in geographic and product
markets which have historically been limited by law and regulation to depository
institutions, such as the Bank.
 
    Changes in the laws, regulations, or policies that impact the Company and
the Bank cannot necessarily be predicted and may have a material affect on the
business and earnings thereof.
 
ITEM 2. PROPERTIES
 
    At December 31, 1997, the Company operated 240 full service branches and 33
limited service offices in California, 5 full service branches in Oregon and
Washington, and 18 overseas branches and business offices. The Company owns the
property occupied by 87 of the domestic offices and leases the remaining
properties for periods of five to twenty years.
 
    The Company owns 3 administrative facilities in San Francisco and 3 in San
Diego. Other administrative offices in Los Angeles, Portland, Seattle, and New
York operate under long-term leases expiring in three to fifteen years.
 
    Rental expense for branches and administrative premises are included in Note
4 to the Company's Consolidated Financial Statements.
 
ITEM 3. LEGAL PROCEEDINGS
 
    The Company is subject to various pending and threatened legal actions which
arise in the normal course of business. The Company maintains reserves for
losses from legal actions which are both probable and estimable. In the opinion
of management, the disposition of claims currently pending will not have a
material adverse effect on the Company's financial position or results of
operations.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
    None.

    Management's discussion and analysis (MD&A) of the consolidated financial
position and results of operations of the Company for the years ended December
31, 1997, 1996 and 1995 should be read in conjunction with the Company's
Consolidated Financial Statements and Notes to Consolidated Financial
Statements. Averages as presented in the following tables are substantially all
based upon daily average balances.
 
    THIS DOCUMENT MAY CONTAIN FORWARD-LOOKING STATEMENTS THAT ARE SUBJECT TO
RISKS AND UNCERTAINTIES THAT COULD CAUSE ACTUAL RESULTS TO DIFFER MATERIALLY

MERGER ACCOUNTING
 
    The combination of Union Bank with BanCal Tri-State Corporation and its
banking subsidiary, The Bank of California, N.A., was completed on April 1,
1996, (the Merger) resulting in UnionBanCal Corporation (UNBC) and its banking
subsidiary, Union Bank of California, N.A. (the Bank). 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 Selected
Financial Data table on page F-1 includes certain pro forma earnings disclosures
and ratios. These presentations supplement the Consolidated Statements of Income
on page F-34 (which are prepared in accordance with generally accepted
accounting principles), primarily with respect to the treatment of merger and
integration expense. Management believes that it is meaningful to understand the
operating results and trends excluding these expenses and, therefore, has
included information in this table and in the MD&A which follows, that presents
income before merger and integration expense and income taxes and related pro
forma ratio and per share calculations.
 
    On August 10, 1998, UNBC and its consolidated subsidiaries (the Company)
exchanged 10.2 million shares of its common stock for the 7.2 million shares of
the Bank's common stock owned directly by the Bank of Tokyo-Mitsubishi, Ltd.
(BTM). This share exchange provides the Company with a 100 percent ownership
interest in the Bank. In addition, it increases BTM's ownership percentage of
the Company to 82 percent from 81 percent.
 
    The exchange of shares was accounted for as a reorganization of entities
under common control. Accordingly, amounts previously reported as Parent Direct
Interest in Bank Subsidiary, including the proportionate share of net income,
dividends, and other comprehensive income have been reclassified to combine them
with the corresponding amounts attributable to the Company's common shareholders
for all periods presented.
 
    On November 18, 1998, the Company's Board of Directors approved the
declaration of a 3-for-1 stock split effective for shareholders of record on
December 7, 1998. Accordingly, all historical financial information has been
restated as if the stock split had been in effect for all periods presented.
 
OVERVIEW
 
    Net income in 1997 was $411 million, including $4 million (after-tax) of
merger and integration related expense. Net income in 1996 was $249 million,
including $72 million (after-tax) of merger and integration related expense. Net
income applicable to common stock was $404 million, or $2.30 per diluted common
share, in 1997 compared with $238 million, or $1.36 per diluted common share, in
1996. Excluding after-tax merger and integration expense, pro forma earnings for
1997 were $415 million, an increase of 29 percent from $321 million a year
earlier. Pro forma earnings applicable to common stock were $407 million, or
$2.32 per diluted common share, in 1997 compared with $310 million, or $1.77 per
diluted common share, in 1996. This increase of 31 percent over the comparable
figures for 1996 was due to a 5 percent increase in net interest income, an 11
percent increase in noninterest income, a decrease in
 
                                      F-2

the effective income tax rate, and a $40 million reduction in the provision for
credit losses, partially offset by a 2 percent increase in noninterest expense
(excluding merger and integration expense). Other highlights for 1997 include:
 
    - Net interest income, on a taxable-equivalent basis, was $1,237 million in
      1997, an increase of $62 million, or 5 percent, over 1996 primarily due to
      a $1.6 billion, or 6 percent, increase in average earning assets,
      resulting primarily from a $1.1 billion, or 5 percent, increase in average
      loans and largely funded by an $851 million, or 13 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
      5 basis point decline in the net interest margin to 4.70%. The decline in
      net interest margin was primarily due to a 14 basis point decrease in the
      spread between the average yield on earning assets and the average rate
      paid on interest bearing liabilities.
 
    - No provision for credit losses was recorded in 1997 compared with $40
      million in 1996, reflecting improvement in the quality of the Company's
      loan portfolio and a reduction in nonaccrual loans. Nonperforming assets
      declined $27 million, or 17 percent, from December 31, 1996 to $130
      million at December 31, 1997. Nonperforming assets as a percent of total
      assets declined to 0.42% at December 31, 1997 compared with 0.54% a year
      earlier. Total nonaccrual loans were $109 million at December 31, 1997
      compared with $128 million at year-end 1996, resulting in a reduction in
      the ratio of nonaccrual and renegotiated loans to total loans from 0.61%
      at December 31, 1996 to 0.48% at year-end 1997. The allowance for credit
      losses was $452 million, or 413% of total nonaccrual loans, at December
      31, 1997 compared with $524 million, or 408% of total nonaccrual loans, at
      December 31, 1996.
 
    - Noninterest income was $463 million in 1997, an increase of $44 million,
      or 11 percent, over 1996. Service charges on deposit accounts grew $13
      million, or 12 percent, reflecting growth in deposit balances while trust
      and investment management fees increased $14 million, or 15 percent, on
      growth in trust accounts and assets under management.
 
    - Excluding merger and integration expense, noninterest expense was $1,039
      million in 1997, an increase of $21 million, or 2 percent, over 1996. This
      increase was primarily attributable to an increase of $14 million, or 3
      percent, in personnel-related expense, a significant portion of which was
      due to severance payments related to realignment of departments and to
      higher performance-related incentive compensation, and an increase of $14
      million, or 25 percent, in other expenses. These increases were partially
      offset by a decline of $18 million in net occupancy expense, reflecting a
      $12 million charge recorded in 1996 related to former banking facilities,
      as well as merger efficiencies realized in 1997. Excluding the $12 million
      charge in 1996 and merger and integration expense, noninterest expense
      increased $33 million over 1996.
 
    - The effective tax rate for 1997 was 37% compared with 40% for 1996.
      Excluding the $25 million after-tax refund from the State of California
      Franchise Tax Board (FTB), the effective tax rate in 1997 was 41%.
      Excluding a $5 million after-tax benefit from the settlement of a unitary
      tax issue with the FTB, the effective tax rate in 1996 was also 41%.
 
    - The return on average assets for 1997 increased to 1.39% compared to 0.89%
      for 1996. Excluding the after-tax effect of merger and integration
      expense, the pro forma return on average assets was 1.40% for 1997
      compared to 1.15% for 1996. The return on average common equity for 1997
      was 16.05% compared to 10.24% for 1996. Excluding the after-tax effect of
      merger and integration expense, the pro forma return on average common
      equity was 16.20% for 1997 compared to 13.33% for 1996.
 
    - Total loans at December 31, 1997 were $22.7 billion, an increase of $1.7
      billion, or 8 percent, over year-end 1996, primarily from growth in the
      commercial, financial and industrial loan portfolio.
 
    - At December 31, 1997, the Tier 1 risk-based capital ratio was 8.96% and
      the total risk-based capital ratio was 11.05%, exceeding the minimum
      regulatory guidelines for bank holding companies of 4% and 8%,
      respectively. The Tier 1 and total risk-based capital ratios for the Bank
      at December 31, 1997 exceeded the regulatory guidelines for
      "well-capitalized" banks. The Company's leverage ratio was 8.53% at
      December 31, 1997, exceeding the minimum regulatory guideline for bank
      holding companies.

(1)  Yields and interest income are presented on a taxable-equivalent basis
    using the federal statutory tax rate of 35 percent.
 
(2)  Average balances on loans outstanding include all nonperforming and
    renegotiated loans. The amortized portion of net loan origination fees
    (costs) is included in interest income on loans, representing an adjustment
    to the yield.
 
(3)  Foreign loans and deposits are those loans and deposits originated in
    foreign branches.
 
(4)  Yields on securities available for sale were based on fair value. The
    difference between these yields and those based on amortized cost was not
    significant.
 
(5)  Amounts restated to give retroactive effect to the exchange referred to in
    Note 1 of the accompanying notes to Consolidated Financial Statements.

    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 volume and composition of average interest earning assets and
average interest bearing liabilities.
 
    Excluding the provision for credit losses, net interest income on a
taxable-equivalent basis was $1,237 million in 1997, compared with $1,175
million in 1996. The increase of $62 million, or 5 percent, was primarily
attributable to a $1.6 billion, or 6 percent, increase in average earning assets
largely funded by an $851 million, or 13 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 5 basis point decline in
the net interest margin to 4.70%, primarily as a result of both a 14 basis point
increase in the cost of interest bearing deposits due to a 25 basis point
increase in the Federal Funds rate in March 1997, and a decrease in the average
yield on domestic loans of 8 basis points.
 
    Average earning assets were $26.3 billion in 1997 compared with $24.7
billion in 1996. This growth was primarily attributable to a $1.1 billion, or 5
percent, increase in average loans and a $355 million, or 16 percent, increase
in average securities. Average commercial, financial and industrial loans, which
increased $582 million, and average commercial mortgage loans, which increased
$437 million, contributed most of the loan growth. See "Loans" at F-11 for
additional commentary on loan portfolio growth. The increase in primarily fixed
rate securities reflected interest rate risk management actions to reduce the
Company's exposure to declines in interest rates.
 
    The $1.6 billion, or 6 percent, increase in average earning assets over 1996
was primarily funded by increases in average demand deposits and average
interest bearing core deposits. Increases in these categories were: demand
deposits $851 million, or 13 percent; interest bearing domestic deposits $340
million, or 7 percent; and savings and consumer time deposits $133 million, or 5
percent. The increase in demand deposits in 1997 was partially due to an influx
of new customer relationships, arising from the recent merger and acquisition
activities of other financial institutions in the California market during the
year.

ANALYSIS OF CHANGES IN NET INTEREST INCOME
 
    The following table shows the changes in the components of net interest
income on a taxable-equivalent basis. The changes in net interest income between
periods have been reflected as attributable either to volume or rate changes.
For purposes of this table, changes which are not solely due to volume or rate
changes are allocated to rate.

(1)  Foreign loans and deposits are those loans and deposits originated in
    foreign branches.
 
    Interest income on a taxable-equivalent basis increased $105 million in
1997, primarily due to growth in interest income from domestic loans and
securities, which reflected higher average balances outstanding, partially
offset by a lower average yield primarily on domestic loans.
 
    Interest expense increased $43 million in 1997 due to higher interest
expense on interest bearing deposits, primarily reflecting higher average
deposit balances and higher average rates. Interest expense on borrowed funds
declined $21 million in 1997, reflecting lower volumes, offset by a 2 basis
point increase in the average rate paid.

    Noninterest income in 1997 was $463 million, an increase of $44 million, or
11 percent, over 1996. This included a $13 million increase in revenue from
service charges on deposit accounts, a $14 million increase in trust and
investment management fees, a $7 million increase in credit card merchant fees,
a $3 million increase in foreign exchange trading gains, net, a $3 million
increase in brokerage commissions and fees, and a $5 million increase in other
noninterest income, partially offset by a $2 million decrease in securities
gains, net.
 
    Revenue from service charges on deposit accounts was $115 million in 1997,
an increase of 12 percent over 1996. The increase was primarily attributable to
an increase in the volume of non-credit services provided.
 
    Trust and investment management fees were $108 million in 1997, 15 percent
higher than in 1996, primarily due to an increase in assets under management,
which resulted in higher mutual fund management fees and personal trust fees.
 
    Credit card merchant fees were $57 million in 1997, an increase of 15
percent over 1996. The increase was primarily due to an increase in the volume
of credit card drafts deposited by merchants.
 
    Foreign exchange trading gains, net increased $3 million, or 23 percent, in
1997, primarily due to more volatility in the foreign exchange markets in 1997.
 
    Brokerage commissions and fees were $16 million in 1997, an increase of 20
percent over 1996. The increase was primarily attributable to brokerage
commissions on non-proprietary mutual fund sales.
 
    Other noninterest income in 1997 was $5 million, or 10 percent, higher than
in 1996. Included in other noninterest income in 1997 was an $8 million gain
related to a real estate joint venture, compared with gains of $2 million
related to a real estate joint venture and $2 million related to a non-recurring
insurance refund recognized in 1996.

    Noninterest expense, excluding merger and integration expense, was $1,039
million in 1997, an increase of $21 million, or 2 percent, over 1996. This
included a $14 million increase in personnel-related expense, a $5 million
increase in credit card processing expense, a $4 million increase in data
processing expense, and a $14 million increase in other noninterest expense,
partially offset by an $18 million decrease in net occupancy expense and a $4
million decrease in foreclosed asset expense.
 
    Personnel-related expense was $572 million in 1997, an increase of $14
million, or 3 percent, compared to 1996. This increase was primarily due to the
increase in salaries and other compensation expense, a significant portion of
which was due to severance payments related to realignment of departments and to
higher performance-related incentive compensation.
 
    Credit card processing expense was $42 million in 1997, an increase of $5
million, or 14 percent, over 1996 due to higher merchant volumes.
 
    Data processing expense was $26 million in 1997, an increase of $4 million,
or 17 percent, over 1996 due to increased activity in data processing systems
supporting the growth in deposits.
 
    Other noninterest expense increased $14 million in 1997. Of the total
increase, $7.5 million reflected additional expenses incurred to support higher
deposit volumes.
 
    Net occupancy expense was $86 million in 1997, $18 million, or 17 percent,
lower than the previous year. The decrease in net occupancy expense was
primarily due to a $12 million charge related to former
 
                                      F-8
<PAGE>
banking facilities in 1996. Excluding this charge, net occupancy expense in 1997
declined 6 percent due to merger-related efficiencies realized in 1997.
 
    Foreclosed asset expense decreased $4 million in 1997. The decrease was
primarily due to lower writedowns and maintenance and selling expenses,
reflecting a 28 percent reduction in the portfolio of foreclosed assets.
 
YEAR 2000
 
    The Year 2000 issue is a computer programming situation that may affect many
electronic data processing systems. In order to minimize the length of data
fields, most computer programs eliminated the first two digits in the year date
field. This problem could affect date-sensitive calculations that treat "00" as
the year 1900, rather than 2000. Secondly, years that end in "00" are not leap
years, except for the anomaly in the year 2000. This anomaly could result in
miscalculations when processing critical date-sensitive information after
December 31, 1999.
 
    The Company has prepared a project plan, identified all the major
application and processing systems, and sought external and internal resources
to replace and test the systems. Purchased software and systems supported by
external parties will be tested as part of the formal project plan. In addition,
customers and vendors who have significant relationships with the Company will
be evaluated to determine whether they are preparing for the Year 2000. The
failure of those customers to adequately prepare will be incorporated into the
credit review process. However, there can be no guarantee that the systems of
vendors or customers with which the Company does business will be completed on a
timely basis. The Company plans to complete the Year 2000 project well in
advance of December 31, 1999. Of the estimated total project cost of $40
million, the remaining amount to be incurred for the Year 2000 project is $38
million and will be funded by normal operating cash and staffed by external
resources as well as internal staff redeployed from less time-sensitive
assignments. Approximately $10 million of the remaining cost is attributable to
the purchase of new hardware and software, which will be capitalized and
expensed over the useful lives of those assets. The remaining $28 million, which
will be expensed as incurred over the next two years, is not expected to have a
material effect on the results of operations, liquidity or capital resources.
During 1997, the Company incurred and expensed approximately $2 million related
to its assessment of the Year 2000 issue and its preliminary efforts in
implementing the Year 2000 project plan. As with all financial institutions,
there is a high degree of reliance being placed on the systems of other
institutions to properly settle transactions. Their inability to process
transactions properly or the Company's inability to complete its plan on time
could have a material adverse effect on the Company.
 
    The cost of the project and the date on which the Company plans to complete
the Year 2000 modifications are based on management's best estimates, which were
derived utilizing a number of assumptions of future events including the
continued availability of internal and external resources, third party
modifications and other factors. However, there can be no guarantee that these
estimates will be achieved and actual results could differ.
 
MERGER AND INTEGRATION EXPENSE
 
    Merger and integration expense of $124 million in total was recorded in 1997
and 1996 to cover $38 million of personnel expense for severance, retention and
other employee related costs, $54 million for facilities expense related to
redundant banking facilities and $32 million in professional services and other
expense as a result of the Merger.

</TABLE>
 
    The Company's effective tax rate in 1997 was 37% compared with 40% in 1996.
The lower 1997 effective tax rate was the result of an after-tax refund from the
FTB of approximately $25 million to settle litigation, administration, and audit
disputes covering the years 1975-1987. Excluding the FTB refund, the effective
tax rate for 1997 was 41%. Excluding a $5 million after-tax benefit recognized
in 1996 from a settlement with the FTB for 1985 and 1986, the effective tax rate
in 1996 was also 41%.
 
CREDIT RISK MANAGEMENT
 
    The Company's principal business activity is the extension of credit in the
form of loans or other credit substitutes to individuals and businesses. The
Company's policies and applicable laws and regulations governing the extension
of credit require risk analysis as well as ongoing portfolio and credit
management through loan product diversification, lending limit constraints,
credit review and approval policies, and extensive internal monitoring.
 
    The Company manages and controls credit risk through diversification of the
portfolio by type of loan, industry concentration, dollar limits on multiple
loans to the same borrower, geographic distribution and type of borrower.
Geographic diversification of loans originated through the Company's branch
network is generally within California, Oregon and Washington, which the Company
considers to be its principal markets. In addition, the Company will continue to
originate and participate in lending activities outside these states, as well as
internationally.
 
    In analyzing the Company's existing loan portfolios, the Company applies
specific monitoring policies and procedures which vary according to the relative
risk profile and other characteristics of the loans within the various
portfolios. The Company's residential and consumer loans are relatively
homogeneous and no single loan is individually significant in terms of its size
or potential risk of loss. Therefore, the Company reviews its residential and
consumer portfolios by analyzing their performance as a pool of loans. In
contrast, the Company's monitoring process for the commercial, financial and
industrial; construction;
 
                                      F-10
<PAGE>
commercial mortgage; and foreign loan portfolios includes a periodic review of
individual loans. Loans that are performing but have shown some signs of
weakness are subjected to more stringent reporting and oversight. The Company
reviews these loans to assess the ability of the borrowing entity to continue to
service all of its interest and principal obligations and as a result may adjust
the risk grade accordingly. In the event that the Company believes that full
collection of principal and interest is not reasonably assured, the loan will be
appropriately downgraded and, if warranted, placed on nonaccrual status, even
though the loan may be current as to principal and interest payments.
 
    The Company has a Credit Policy Forum, composed of the Chief Credit Officer,
senior credit officers, and appropriate line officers who establish policy,
credit quality criteria, portfolio guidelines and other controls. Credit
Administration together with a series of loan committees, have the
responsibility for administering the credit approval process, as well as the
implementation and administration of the Company's credit policies and lending
practices and procedures. These policies require an extensive evaluation of
credit requests and continuing review of existing credits in order to promptly
identify, monitor and quantify evidence of deterioration of asset credit quality
or potential loss.
 
    As another part of the control process, an independent internal credit
review and examination function provides quality assurance that loans and
commitments are made and maintained as prescribed by the Company's credit
policies and that the assets are appropriately and timely risk graded. This
includes a review of compliance with the Company's underwriting policies when
the loan is initially extended and subsequent on-site examinations to ensure
continued compliance.

    The Company's lending activities are predominantly domestic, with such loans
comprising approximately 93 percent of the portfolio at December 31, 1997. Total
loans at December 31, 1997 were $22.7 billion, an increase of $1,691 million, or
8 percent, from one year earlier. The increase was primarily attributable to
growth in the commercial, financial and industrial loan portfolio, which
increased $1,251 million from 1996, and to growth in the commercial mortgage
loan portfolio, which increased $354 million.
 
COMMERCIAL, FINANCIAL AND INDUSTRIAL LOANS
 
    Commercial, financial and industrial loans represent the largest category in
the loan portfolio. These loans are extended principally to major corporations,
middle market businesses, and small businesses, with no industry concentration
exceeding ten percent of total commercial, financial and industrial loans.
 
    The Company's commercial market lending originates primarily through its
banking office network. These offices, which rely extensively on relationship
oriented banking, provide many services including cash management services,
lines of credit, accounts receivable and inventory financing. Separately, the
Company originates or participates in a wide variety of financial services to
major corporations. These services include traditional commercial banking and
specialized financing tailored to the needs of each customer's specific
industry. Presently, the Company is active in the communications and media,
energy related services, retailing and financial services industries.
 
    At December 31, 1997, the commercial, financial and industrial loan
portfolio was $10,747 million, or 47 percent, of the total loan portfolio. The
increase of $1,251 million, or 13 percent, from the previous year-end was
primarily attributable to loans extended to large corporations in industries
where the Bank has specialized lending expertise.
 
CONSTRUCTION AND COMMERCIAL MORTGAGE LOANS
 
    The Company engages in nonresidential real estate lending which includes
commercial mortgage loans and construction loans secured by deeds of trust.
Construction loans are made primarily to residential builders and to commercial
property developers.
 
    At December 31, 1997, construction loans were $293 million, $65 million
lower than at the end of the previous year. Commercial mortgage loans were
$2,952 million, an increase of $354 million, or 14 percent, from a year earlier.
This increase was primarily attributable to a strong recovery in the California
real estate market reflecting the continuing improvement in the West Coast
economy, particularly in the real estate sector.
 
RESIDENTIAL MORTGAGE LOANS
 
    The Company originates residential loans through its branch network in
California, Oregon, and Washington, and periodically purchases loans in its
market area.
 
    At December 31, 1997, residential loans were $2,961 million, unchanged from
the prior year.
 
CONSUMER LOANS
 
    Through its branch network, the Company originates consumer loans, such as
vehicle-secured installment loans, home equity lines where advances are
generally secured by second deeds of trust on residential real estate, and
credit card loans.
 
    At December 31, 1997, consumer loans were $3,354 million, or 15 percent of
total loans, compared with $3,479 million, or 16 percent of total loans, at
year-end 1996.

LEASE FINANCING
 
    The Company enters into direct financing and leveraged leases through an
agreement with a subsidiary of BTM. In addition, the Company originates auto
leases.
 
    At December 31, 1997, lease financing outstandings were $875 million, an
increase of $75 million from the end of 1996.
 
LOANS ORIGINATED IN FOREIGN BRANCHES
 
    The Company's loans originated in foreign branches consist primarily of
short-term credit extensions to financial institutions located primarily in Asia
and short-term commercial and industrial loans to major Japanese, Korean, and
Taiwanese corporations.
 
    At December 31, 1997, loans originated in foreign branches totaled $1,559
million, or 7 percent of the total loan portfolio, compared with $1,358 million,
or 7 percent of total loans, at December 31, 1996.
 
CROSS-BORDER OUTSTANDINGS
 
    The Company's cross-border outstandings reflect certain additional economic
and political risks that are not reflected in domestic outstandings. These risks
include those arising from exchange rate fluctuations and restrictions on the
transfer of funds. The following table sets forth the Company's cross-border
outstandings as of December 31, 1997, 1996 and 1995 for each country where such
outstandings exceeded one percent of total assets. The cross-border outstandings
were compiled based upon category and domicile of ultimate risk and are
comprised of balances with banks, trading securities, securities available for
sale, securities purchased under resale agreements, loans, accrued interest
receivable, acceptances outstanding and investments with foreign entities. The
amounts outstanding for each country exclude local currency outstandings. The
Corporation does not have significant local currency outstandings to the
individual countries listed in the following table that are not hedged or are
not funded by local currency borrowings.

    The economic condition and the ability of some countries, to which the
Company has cross-border exposure, to manage their external debt obligations
have been impacted by the Asian economic crisis beginning in the second half of
1997. The events leading to the crisis included currency devaluations, business
failures, principally caused by excessive debt levels and overcapacity, and some
loss of confidence in the banking system in the affected countries, resulting
mainly from past lending practices and the associated impact of internal and
external economic conditions. The crisis resulted in a substantial erosion of
international confidence, rapid declines in stock market valuations, steep
increases in interest rates and further pressure on the debt structures of the
corporate and financial market participants. International Monetary Fund
programs have been established or are in the process of being established which,
in co-operation with steps being taken by the local governments and other global
institutions, are designed to restore confidence. The success of these programs
is still being evaluated.
 
                                      F-13
<PAGE>
    The Company is managing its exposures in these and other impacted countries
very cautiously with a view to minimizing risk and supporting its long term and
viable customer relationships. High risk situations are being identified and
reduced where possible, and additional reserves against potential credit losses
have been identified and allocated, as determined by management at year end.
None of the Company's cross-border exposure has been subject to the recently
announced debt restructuring program with South Korea.
 
    Although management cannot predict the ultimate impact of the crisis on the
Company's financial position and results of operations since much depends on the
effect of the stabilizing activities already under way, management believes that
the continuation of internal supervision, monitoring and portfolio risk
management practices will be effective in minimizing the impact over and above
that already identified. Increases in non-accrual loans, together with some
related increases in charge-off activity, may occur as events unfold.
 
    Management, in accordance with its established risk management practices,
will also continue to review the impact of the crisis on the stability of other
countries and the potential impact on domestic business activities, particularly
in our core West Coast markets.
 
PROVISION FOR CREDIT LOSSES
 
    The Company did not record a provision for credit losses during 1997,
compared with a $40 million provision that was recorded in 1996. Provisions for
credit losses are charged to income to bring the Company's allowance for credit
losses to a level deemed appropriate by management based on the factors
discussed under "--Allowance for Credit Losses" below. No provision for credit
losses was recorded in 1997 because, based on its review of such factors,
management believed that the allowance for credit losses was adequate to cover
probable losses inherent in the loan and lease portfolio and firm commitments at
each quarter end, including December 31, 1997.
 
ALLOWANCE FOR CREDIT LOSSES
 
    The Company maintains an allowance for credit losses to absorb losses
inherent in the loan and lease portfolio. The allowance is based on ongoing,
quarterly assessments of the probable estimated losses inherent in the loan and
lease portfolio, and to a lesser extent, unused commitments to provide
financing. The Company's methodology for assessing the appropriateness of the
allowance consists of several key elements, which include the formula allowance,
specific allowances for identified problem loans and portfolio segments and the
unallocated allowance. In addition, the allowance incorporates the results of
measuring impaired loans as provided in Statement of Financial Accounting
Standards ("SFAS") No. 114, "Accounting by Creditors for Impairment of a Loan"
and SFAS No. 118, "Accounting by Creditors for Impairment of a Loan--Income
Recognition and Disclosures." These accounting standards prescribe the
measurement methods, income recognition and disclosures related to impaired
loans.
 
    The formula allowance is calculated by applying loss factors to outstanding
loans and leases and certain unused commitments, in each case based on the
internal risk grade of such loans, pools of loans, leases or commitments.
Changes in risk grades of both performing and nonperforming loans affect the
amount of the formula allowance. Loss factors are based on the Company's
historical loss experience and may be adjusted for significant factors that, in
management's judgment, affect the collectibility of the portfolio as of the
evaluation date. Loss factors are described as follows:
 
    - Problem graded loan loss factors are derived from a migration model that
      tracks four years of historical loss experience. The Company is exploring
      changes to the migration model to track historical loss experience over an
      eight-year period, which management believes approximates a business
      cycle.
 
    - Pass graded loan loss factors are based on the average annual net
      chargeoff rate over a six-year period.
 
                                      F-14
<PAGE>
    - Pooled loan loss factors (not individually graded loans) are based on
      expected net chargeoffs for one year. Pooled loans are loans and leases
      that are homogeneous in nature, such as consumer installment and
      residential mortgage loans and automobile leases.
 
    Specific allowances are established in cases where management has identified
significant conditions or circumstances related to a credit that management
believes indicate the probability that a loss has been incurred in excess of the
amount determined by the application of the formula allowance.
 
    The unallocated allowance is composed of two elements. The first element,
which is based on the Company's credit policy, consists of an amount that is at
least 20% to 25% of the formula allowance and the specific allowance. This
element recognizes the model and estimation risk associated with the formula and
specific allowances. The second element is based upon management's evaluation of
various conditions, the effects of which are not directly measured in the
determination of the formula and specific allowances. The evaluation of the
inherent loss with respect to these conditions is subject to a higher degree of
uncertainty because they are not identified with specific problem credits or
portfolio segments. The conditions evaluated in connection with the unallocated
allowance include the following conditions that existed as of the balance sheet
date:
 
    - then-existing general economic and business conditions affecting the key
      lending areas of the Company,
 
    - credit quality trends (including trends in nonperforming loans expected to
      result from existing conditions),
 
    - collateral values,
 
    - loan volumes and concentrations,
 
    - seasoning of the loan portfolio,
 
    - specific industry conditions within portfolio segments,
 
    - recent loss experience in particular segments of the portfolio,
 
    - duration of the current business cycle,
 
    - bank regulatory examination results and
 
    - findings of the Company's internal credit examiners.
 
Executive management reviews these conditions quarterly in discussion with the
Company's senior credit officers. To the extent that any of these conditions is
evidenced by a specifically identifiable problem credit or portfolio segment as
of the evaluation date, management's estimate of the effect of such condition
may be reflected as a specific allowance applicable to such credit or portfolio
segment. Where any of these conditions is not evidenced by a specifically
identifiable problem credit or portfolio segment as of the evaluation date,
management's evaluation of the probable loss related to such condition is
reflected in the unallocated allowance.
 
    The allowance for credit losses is based upon estimates of probable losses
inherent in the loan and lease portfolio. The amount actually observed in
respect of these losses can vary significantly from the estimated amounts. The
Company's methodology includes several features which are intended to reduce the
differences between estimated and actual losses. The loss migration model that
is used to establish the loan loss factors for problem graded loans is designed
to be self-correcting by taking into account the Company's recent loss
experience. Similarly, by basing the pass graded loan loss factors on loss
experience over the last six years, the methodology is designed to take the
Company's recent loss experience into account. Pooled loan loss factors are
adjusted quarterly based upon the level of net chargeoffs expected by management
in the next twelve months. Furthermore, the Company's methodology permits
adjustments to any loss factor used in the computation of the formula allowance
in the event that, in management's
 
                                      F-15
<PAGE>
judgment, significant factors which affect the collectibility of the portfolio
as of the evaluation date are not reflected in the loss factors. By assessing
the probable estimated losses inherent in the loan and lease portfolio on a
quarterly basis, the Company is able to adjust specific and inherent loss
estimates based upon any more recent information that has become available.
 
    The following table sets forth the allocation of the allowance for credit
losses. The percentages reflect the allowance allocated to each respective loan
category at period end, as a percentage of the total period end balance of that
loan category, as set forth in the "Loans" table at F-11.

(1)  Foreign loans are those loans originated in foreign branches.
 
    At December 31, 1997, the Company's allowance for credit losses was $452
million, or 1.99% of the total loan portfolio, and 413% of total nonaccrual
loans. This compares with an allowance for credit losses of $524 million, or
2.49% of the total loan portfolio, and 408% of total nonaccrual loans at
December 31, 1996. At year-end 1997, the unallocated portion of the allowance
for credit losses was $172 million compared with $245 million at the end of
1996. At December 31, 1997, the allocated portion of the allowance for credit
losses included $108 million related to special mention and classified credits,
compared to $134 million at December 31, 1996. Special mention and classified
credits are those that are internally risk graded as "special mention,"
"substandard" or "doubtful." Special mention credits are potentially weak, as
the borrower has begun to exhibit deteriorating trends which, if not corrected,
could jeopardize repayment of the loan and result in further downgrade.
Substandard credits have well-defined weaknesses which, if not corrected, could
jeopardize the full satisfaction of the debt. A credit classified as "doubtful"
has critical weaknesses that make full collection improbable.
 
    During 1997, there were no changes in estimation methods or assumptions that
affected the Company's methodology for assessing the appropriateness of the
allowance for credit losses, except that the Company extended the average annual
net chargeoff rate for pass graded loans from 4.75 years to 6 years. The impact
of this change resulted in an increase of approximately $13 million in the
formula allowance. The Company extended the average annual net chargeoff rate in
order to better reflect the business cycle. Changes in assumptions regarding the
effects of economic and business conditions on borrowers and other factors,
which are described below, affected the assessment of the unallocated allowance.
In addition, as described below, the Company allocated a portion of the
unallocated allowance to foreign loans amid concerns that the Asian financial
turmoil had adversely impacted companies and financial institutions in Asian
markets in which the Company operates.
 
                                      F-17
<PAGE>
    During 1997, the Company had net loans charged off of $72 million compared
to net loans charged off of $71 million in 1996. Recoveries of loans previously
charged off increased by $3 million, and the percentage of current year
recoveries to loans charged off in the previous year increased from 35.95% in
1996 to 42.83% in 1997. Loans charged off in 1997 increased by $4 million,
primarily due to a $17 million increase in commercial, financial and industrial
loans charged off, partially offset by a $8 million decrease in mortgage loans
charged off. Chargeoffs reflect the realization of losses in the portfolio that
were recognized previously through provisions for credit losses. At December 31,
1997, the allowance for credit losses exceeded the net loans charged off during
1997, reflecting management's belief, based on the foregoing analysis, that
there are additional losses inherent in the portfolio.
 
    At December 31, 1997, the Company's average annual net chargeoffs for the
past five years were $131.2 million, compared with $166.4 million at December
31, 1996. These net chargeoffs represent 3.4 years and 3.1 years of losses based
on the level of the allowance for credit losses at December 31, 1997 and 1996,
respectively. Historical net chargeoffs are not necessarily indicative of the
amount of net chargeoffs that the Company will realize in the future.
 
    The Company did not record a provision for credit losses during 1997. The
decision not to record a provision was based upon management's application of
the allowance methodology and the factors described above, in particular, the
level of net chargeoffs and the decline in the level of nonperforming loans.
Although management determined that no provision for credit losses was necessary
in 1997, it noted that certain factors could necessitate the resumption of
provisioning in the future. In particular, management noted that although net
chargeoffs were relatively stable from 1996 to 1997, net chargeoffs were higher
in the last three quarters of 1997. Furthermore, management noted that although
the level of net chargeoffs and the decline in nonperforming loans favorably
impacted the Company's asset quality ratios, the total portfolio of commercial,
financial and industrial loans and commercial mortgage loans was increasing.
Losses inherent in both of these types of credits are more difficult to assess
because historically they have been more volatile than losses from other
credits.
 
    Management also considered the effect on global economic conditions of the
Asian financial crisis. At December 31, 1997, cross-border loans and acceptances
to Japan, Korea, Malaysia, Thailand, Vietnam, Singapore, Indonesia, the
Philippines, China, Taiwan and Hong Kong totaled $2.1 billion. Although at
December 31, 1997, the Company had not identified any specific losses related to
its Asia/Pacific exposures, management believed that it was probable that the
Asian financial turmoil had adversely impacted companies and financial
institutions in Asia/Pacific markets in which the Company operates. In light of
this concern, the Company allocated $29 million from the unallocated portion of
the allowance at December 31, 1997 to foreign loans. The allocated amount was
based upon the total amount of foreign loans to corporate borrowers in Asian
countries, and management's assessment of the quantified losses inherent in the
Asia/Pacific portfolio segment. In addition, the Company believes that the
historical loss factors for the Asia/Pacific exposures failed to estimate the
total probable inherent losses because the Company had not suffered any credit
losses in the foreign loan portfolio during the four-year historical loss cycle
used to establish the problem loan loss factors. Based upon this concern, as
well as the other factors described in "Cross-Border Outstandings" above,
including the magnitude of the Company's exposure to the Asia/Pacific segment,
management does not believe that the $29 million allocated to foreign loans is
sufficient to cover all of the losses inherent in the foreign loan portfolio
and, accordingly, these factors were considered by management in its overall
assessment of the unallocated allowance.
 
    In addition to the impact of the Asian financial turmoil on companies and
financial institutions in Asian markets in which the Company operates,
management considered the effects of the Asian turmoil on companies and
financial institutions in the domestic (primarily California) and foreign (other
than Asia/ Pacific) markets in which the Company operates. As of December 31,
1997, management believed that the impact of the Asian financial turmoil on the
collectibility of loans and leases to domestic and foreign (non-Asia/Pacific)
borrowers was not generally reflected in the level of nonperforming loans or in
the internal risk grading process with respect to such loans and leases.
Accordingly, the Company's evaluation of these
 
                                      F-18
<PAGE>
probable losses is reflected in the unallocated allowance. The evaluations of
these inherent losses are subject to higher degrees of uncertainty because they
are not identified with specific problem credits.
 
    At December 31, 1997, the Company's allowance for credit losses was $452
million, consisting of a $212 million formula allowance, a $68 million specific
allowance and a $172 million unallocated allowance. This compares with an
allowance for credit losses of $524 million at December 31, 1996, which
consisted of a $237 million formula allowance, a $42 million specific allowance
and a $245 million unallocated allowance. The decrease of $25 million in the
formula allowance relates primarily to a reduction in the level of criticized
loans and the reflection of lower historical losses in the loss factors, which
was partially offset by loan growth, by changes to conform the various risk
grade definitions after the combination of Bank of California and Union Bank and
by the extension of the average annual net chargeoff rate for pass graded loans.
The increase of $26 million in the specific allowance relates primarily to the
reallocation for the Asian exposure which is described above. The unallocated
allowance decreased by $73 million at December 31, 1997, because management
believed that the inherent losses related to certain conditions considered in
its evaluation of the unallocated allowance at December 31, 1996 had been
recognized through chargeoffs, had been reflected in the formula or specific
allowance or had declined. From December 31, 1996 to December 31, 1997, there
was no change in the component of the unallocated allowance related to the 20%
to 25% margin for model and estimation risk prescribed by the Company's credit
policy. Included among those conditions that management believed gave rise to
lower inherent losses at December 31, 1997 compared to December 31, 1996 were:
 
    - reduced concerns regarding the lingering effects of the California
      recession on, and the sustainability of the recovery in, the California
      commercial real estate and construction market,
 
    - reduced concerns regarding consumer debt burdens and rising levels of
      consumer bankruptcies,
 
    - resolution of uncertainties related to assimilating data for the formula
      allowance that resulted from combining the loan portfolios of Bank of
      California and Union Bank and inconsistencies in the risk grading systems
      of the Company's predecessor banks,
 
    - reduced concerns related to consolidation and restructuring in the retail
      industry and
 
    - reduced concerns regarding the sustainability of perceived improvements in
      economic conditions.
 
    The Company does not weight the unallocated allowance among segments of the
portfolio. In evaluating the appropriateness of the unallocated allowance at
December 31, 1997, the Company considered, in addition to the factors described
above:
 
    - the approximately $56 million to $70 million margin for model and
      estimation risk prescribed by the Company's credit policy and
 
    - the Company's estimate that the adverse impact of the Asian financial
      turmoil on the Company could be in the range of $100 million to $105
      million.
 
    The following factors are reflected in management's estimate of the
unallocated allowance at December 31, 1996:
 
    - the approximately $56 million to $70 million margin for model and
      estimation risk prescribed by the Company's credit policy,
 
    - the lingering effects of the California recession on, and the
      sustainability of the recovery in, the California commercial real estate
      and construction market, which could be in the range of $45 million to $70
      million,
 
    - the effects of consumer debt burdens and rising levels of consumer
      bankruptcies, which could be in the range of $25 million to $40 million,
 
                                      F-19
<PAGE>
    - the effects of uncertainties related to assimilating data for the formula
      allowance that resulted from combining the loan portfolios of Bank of
      California and Union Bank and inconsistencies in the risk grading systems
      of the Company's predecessor banks, which could be in the range of $15
      million to $30 million,
 
    - the effects of consolidation and restructuring in the retail industry,
      which could be in the range of $5 million to $10 million and
 
    - the effects of adverse economic and business conditions in Japan, which
      could be in the range of $5 million to $10 million.
 
There can be no assurance that the adverse impact of any such condition on the
Company will not be in excess of the foregoing ranges. See paragraph on forward
looking statements on page F-2.

NONPERFORMING ASSETS
 
    Nonperforming assets consist of nonaccrual loans, renegotiated loans, and
foreclosed assets. Nonaccrual loans are those for which management has
discontinued accrual of interest because there exists significant uncertainty as
to the full and timely collection of either principal or interest or such loans
have become contractually past due 90 days with respect to principal or
interest. For a more detailed discussion of the accounting for nonaccrual loans,
see Note 1 to the Company's Consolidated Financial Statements.
 
    Renegotiated loans are those accruing loans for which, for reasons related
to the borrower's financial difficulties, the Company has amended the terms of
the original loan agreement and the borrower is performing according to the
renegotiated terms.
 
    Foreclosed assets includes property where the Company acquired title through
foreclosure or "deed in lieu" of foreclosure. On an ongoing basis, foreclosed
asset values are reviewed and any decline in value is recognized as noninterest
expense in the current period.
 
    The following table sets forth an analysis of nonperforming assets.

    At December 31, 1997, nonaccrual loans totaled $109 million, a decrease of
$19 million, or 15%, from year-end 1996. The decline was primarily attributable
to a $10 million reduction in nonaccrual commercial, financial and industrial
loans and a $10 million reduction in nonaccrual residential mortgage loans. The
reduction in nonaccrual residential mortgage loans was due in part to a
reclassification of certain loans from nonaccrual to 90-days past due and still
accruing. The decline in nonaccrual loans was reflected in an improvement in the
overall risk grades of the portfolio, which contributed to a reduction in the
formula allowance. Foreclosed assets, primarily other real estate owned,
decreased by $8 million due to sales of individual assets.
 
    Nonaccrual and renegotiated loans as a percentage of total loans were 0.48%
at December 31, 1997 compared with 0.61% one year earlier. Nonperforming assets
as a percentage of total loans, real estate ventures and foreclosed assets
improved to 0.57% at year-end 1997 from 0.74% at December 31, 1996. At December
31, 1997, approximately 58% of nonaccrual loans were real estate related.
 
    Total loans 90 days or more past due and still accruing were $20 million at
December 31, 1997 compared with $24 million at December 31, 1996.
 
    At December 31 1997, impaired loans were $108 million and the associated
impairment allowance was $9 million compared with $114 million and $21 million,
respectively, at December 31, 1996.
 
INTEREST FOREGONE
 
    Interest foregone during 1997 and 1996 for loans that were on nonaccrual
status at December 31, 1997 and 1996 was $6 million and $9 million,
respectively. The Company recognized interest income during 1997 and 1996 for
loans that were on nonaccrual status at December 31, 1997 and 1996 of $3 million
and $5 million, respectively.

issued by the Financial Accounting Standards Board (FASB), the Company
reclassified from securities held to maturity to securities available for sale
approximately $285 million at amortized cost of U.S. Treasury Notes (fair value
$285 million) and $64 million at amortized cost of municipal bonds (fair value

CAPITAL ADEQUACY AND DIVIDENDS
 
    The Company's principal capital objectives are to support future growth, to
protect depositors, to absorb any unanticipated losses and to comply with
various regulatory requirements. Management believes that the Company has
retained its capital at a level which supports the risk structure of the
Company, as well as providing for anticipated growth of current business
activities and strategic expansion.
 
    Total shareholders' equity was $2,679 million at December 31, 1997, an
increase of $184 million from year-end 1996. This change was primarily a result
of $411 million of net income for 1997, offset by the redemption of $135 million
in preferred stock and dividends on common and preferred stock of $97 million.
 
    The Company offers a dividend reinvestment plan that allows shareholders to
reinvest dividends in the Company's common stock at 5 percent below the market
price. At December 31, 1997, BTM was not a participant in the plan.
 
    Capital adequacy depends on a variety of factors including asset quality and
risk profile, liquidity, stability of earnings, competitive and economic
conditions, and management. The Company believes that the current level of
profitability, coupled with a prudent dividend policy, is adequate to support
normal growth in operations while meeting regulatory capital guidelines.

(1)  Tier 1 capital divided by quarterly average assets (excluding intangible
    assets).
 
    For regulatory purposes, the Company's capital computations are based on
risk-adjusted Tier 1 and total capital. The Company's Tier 1 and total
risk-based capital ratios were 8.96% and 11.05%, respectively, at December 31,
1997 compared to 9.08% and 11.17%, respectively, at December 31, 1996. The
decrease in the capital ratios was attributable to the redemption of $135
million of preferred stock in the third quarter of 1997, partly offset by
retained earnings growing faster than both risk-weighted assets and average
assets. As of December 31, 1997, management believes the capital ratios of the
Bank met all regulatory minimums of a "well-capitalized" institution.
 
COMPARISON OF 1996 VERSUS 1995
 
    Net income in 1996 was $249 million compared with $313 million in 1995.
Excluding the effects of the $72 million after-tax charge for merger-integration
expense, net income improved as a result of higher net interest income, higher
noninterest income, and lower credit loss provision expense than in 1995.
 
    Net income applicable to common stock was $238 million, or $1.36 per diluted
common share, in 1996 compared with $302 million, or $1.73 per diluted common
share, in 1995.
 
    The return on average assets was 0.89% in 1996 versus 1.22% in 1995. The
return on average common equity was 10.24% in 1996 compared with 13.73% in 1995.
 
    Net interest income on a taxable-equivalent basis increased by $23 million,
or 2 percent, over 1995. Average loans increased $1,753 million, or 9 percent,
and the net interest margin decreased 30 basis points to 4.75%.
 
    Noninterest income increased by $23 million, or 6 percent, over 1995.
Service charges on deposits, trust and investment management fees, credit card
merchant fees, brokerage commissions and fees, securities gains, and other
revenue collectively grew 11 percent and accounted for $32 million of the growth
in noninterest income. This increase was partially offset by a $6 million
decrease in foreign exchange trading gains.
 
                                      F-27
<PAGE>
    The provision for credit losses was $40 million in 1996, $13 million, or 25
percent, lower than in 1995, reflecting the improved quality of the loan
portfolio.
 
    Noninterest expense, excluding merger and integration expense, increased by
$39 million, or 4 percent, from 1995. Personnel-related expense increased $21
million, or 4 percent, due partially to increased contract labor used to augment
staffing requirements as a residual effect of the merger. Net occupancy expense
increased $10 million, or 11 percent, due to a $12 million one-time charge in
1996 related to former banking facilities. This was offset by a 2 percent
decrease in net occupancy expense due to the closure of 20 branches late in the
third quarter of 1996. Credit card processing expense increased $6 million, or
19 percent, in 1996 due to higher merchant volumes. Advertising and public
relations expense increased $8 million, or 38 percent, over 1995 due primarily
to expanded activities in 1996 to increase awareness of the Bank, following the
April 1, 1996 combination of Union Bank and BanCal Tri-State Corporation and its
subsidiary. In 1996, regulatory authority assessments expense declined $19
million, or 83 percent, primarily because the Federal Deposit Insurance
Corporation decided to eliminate insurance assessments for all of 1996. Merger
and integration expense was $117 million in 1996.
 
    Income tax expense was $30 million lower in 1996 than in 1995, primarily due
to lower taxable income. The effective rate increased from 38% in 1995 to 40% in
1996 primarily due to a $3 million after-tax benefit recognized in 1995 from a
favorable settlement of an Internal Revenue Service examination of 1989 and
1990.
 
    Total loans at December 31, 1996 were $21.0 billion, an increase of $0.6
billion, or 3 percent, over year-end 1995. Commercial, financial and industrial
loans declined $188 million, or 2 percent, from the previous year, primarily due
to planned reductions from a portfolio overlap arising from the merger and a
reduction in certain low margin lending. At year-end 1996, construction loans
decreased $12 million, or 3 percent, while commercial mortgages increased $455
million, or 21 percent, from 1995. This increase in commercial mortgages
reflected the continuing improvement in the West Coast economy, particularly the
real estate sector. It was primarily attributable to new originations of
mini-perm loans, ranging in size from $1 million to $10 million, resulting from
a vigorous marketing program. At December 31, 1996 residential loans were $319
million, or 12 percent, higher than the previous year as the favorable interest
rate environment and a stronger housing market continued to generate significant
opportunities for residential mortgage lenders. Consumer loans increased $136
million, or 4 percent, from 1995 due primarily to increases in direct and
indirect auto loans for used vehicles, partially offset by a decrease in home
equity balances.
 
    Total nonperforming assets were $157 million at December 31, 1996, $90
million, or 36 percent, lower than one year earlier. The decline was primarily
attributable to a $27 million, or 33 percent, reduction in nonaccrual
commercial, financial and industrial loans and a $33 million, or 82 percent,
reduction in nonaccrual construction loans, due to a combination of note sales,
payoffs, and upgrades. Foreclosed assets, primarily other real estate owned,
decreased by $8 million, or 23 percent, from 1995, due to sales of individual
assets. Net loan charge-offs in 1996 were $71 million compared to net loans
charged off of $61 million in 1995. Recoveries of loans previously charged off
decreased by $24 million, despite an increase in the percentage of recoveries in
1996 to loans charged off in the previous year from 26.44% in 1995 to 35.95% in
1996. Loans charged off in 1996 decreased by $14 million due to a reduction in
new nonperforming assets in 1996 and a reduction in nonaccrual and
underperforming loans, partly offset by a $12 million increase in consumer loans
charged off, primarily attributable to credit card loans.
 
    At December 31, 1996, the Tier 1 risk-based capital ratio was 9.08% and the
total risk-based capital ratio was 11.17% compared with ratios of 9.35% and
11.70%, respectively, at December 31, 1995.

RECENT ACCOUNTING DEVELOPMENTS
 
    In addition to the new accounting pronouncements disclosed in Note 1 to the
Consolidated Financial Statements, the FASB issued SFAS No. 132, "Employers'
Disclosures about Pensions and Other Postretirement Benefits" in February 1998.
The Standard revises the disclosure requirements for pensions and other
postretirement benefits. This Statement is effective for fiscal years beginning
after December 15, 1997. Adoption of this Statement 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.
 
QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
 
    GENERAL
 
    Market risk is the risk of loss to future earnings, to fair values, or to
future cash flows that may result from changes in the price of a financial
instrument. The value of a financial instrument may change as a result of
changes in interest rates, foreign currency exchange rates, commodity prices,
equity prices and other market changes that affect market risk sensitive
instruments. Market risk is attributed to all market risk sensitive financial
instruments, including securities, loans, deposits, borrowings, as well as
derivative instruments. The Company's exposure to market risk is a function of
its asset and liability management activities, its trading activities for its
own account, and its role as a financial intermediary in customer-related
transactions. The objective of market risk management is to avoid excessive
exposure of the Company's earnings and equity to loss and to reduce the
volatility inherent in certain financial instruments.
 
    The management of market risk is governed by policies reviewed and approved
annually by the Company's Board of Directors (Board). The Board delegates
responsibility for market risk management to the Asset & Liability Management
Committee (ALCO), who reports quarterly to the Board on activities related to
the management of market risk. As part of the management of the Company's market
risk, the ALCO may direct changes in the mix of assets and liabilities and the
use of derivative instruments such as interest rate swaps, caps and floors. The
ALCO also reviews and approves all major funding, market risk-management
programs, and market risk limits. The Chief Financial Officer (CFO), as chairman
of the ALCO, is responsible for companywide management of market risk. The
Treasurer is responsible for implementing funding, investment, and hedging
strategies designed to manage this risk. On a day-to-day basis, the oversight of
market risk management takes place at a centralized level within the Risk
Monitoring Unit (RMU). The RMU is responsible for measuring risks to ensure
compliance with all market risk limits and guidelines incorporated within the
policies and procedures established by the ALCO. The RMU reports monthly to the
ALCO on the effectiveness of the Company's hedging activities, on trading risk
exposures, and on compliance with policy limits. In addition, periodic reviews
by internal audit, regulators and independent accountants provide further
evaluation of controls over the risk management process.
 
    The Company has separate and distinct methods for managing the market risk
associated with its trading activities and its asset and liability management
activities, as described below.
 
    INTEREST RATE RISK MANAGEMENT (OTHER THAN TRADING)
 
    The Company engages in asset and liability management activities with the
objective of reducing adverse changes in earnings as a result of changes in
interest rates. The management of interest rate risk relates to the timing and
magnitude of the repricing of assets compared to liabilities and has, as its
objective, the control of risks associated with movements in interest rates.
 
    The Asset & Liability Management (ALM) Policy approved by the Board requires
monthly monitoring of interest rate risk by ALCO. As part of the management of
the Company's interest rate risk, ALCO may direct changes in the composition of
the balance sheet and the extent to which the Company utilizes off-balance sheet
derivative instruments such as interest rate swaps, floors, and caps.
 
                                      F-29
<PAGE>
    The Company's balance sheet is "asset-sensitive", which means that assets
generally reprice more quickly than liabilities. An asset-sensitive balance
sheet tends to reduce net interest income when interest rates decline and to
increase net interest income when interest rates rise.
 
    One method of measuring interest rate risk is by measuring the interest rate
sensitivity gap, which is the difference between earning assets and liabilities
maturing or repricing within specified periods. The table on F-32 presents such
an analysis, which reflects certain assumptions as to the rate sensitivity of
deposits without contractual maturities or repricing dates. These include demand
deposits, money market demand accounts, and savings deposits. Additional
assumptions such as prepayment estimates for residential mortgages and
mortgage-backed securities are made to reflect the probable behavior of those
assets. The section of the table on F-32 entitled Interest Rate Risk Management
Positions presents the effects of the securities portfolio and of derivatives
used for hedging, such as interest rate swaps and floors, in reducing the
interest rate sensitivity gap primarily for LIBOR-based loans.
 
    The table on F-32 shows that the Company's assets that are rate sensitive
within one year exceeded liabilities within that same period by $4.9 billion at
December 31, 1997. Adjusted for the effects of the securities portfolio and
derivatives used for hedging, this cumulative gap was reduced to $2.5 billion.
 
    Gap analysis has significant limitations as a method for measuring interest
rate risk since changes in interest rates do not affect all categories of assets
and liabilities in the same way. To address these limitations, the Company uses
a simulation model to quantify the impact of changing interest rates on net
interest income (NII). A frequency distribution of simulated 12-month NII
outcomes based on rate scenarios produced through a Monte Carlo rate generation
process is prepared monthly to determine statistically the mean NII. The amount
of Earnings at Risk (EaR), defined as the potential negative change in NII, is
measured at a 97.5 percent confidence level and is managed within the limit
established in the Board's ALM Policy at 5 percent of mean NII. Based on the
December 31, 1997 balance sheet, the EaR was $23.0 million or 1.80% of mean NII.
 
    An additional limit established by the Board's ALM Policy is that the
negative change in simulated net interest income for 12 months under single
interest rate shock scenarios, up or down 200 basis points, must be no more than
8 percent of the mean NII. Based on the December 31, 1997 balance sheet, the
negative change for a downward shock of 200 basis points was $51.8 million or
4.05% of mean NII.
 
    TRADING ACTIVITIES
 
    The Company enters into trading account activities primarily as a financial
intermediary for customers, and, to a lesser extent, for its own account. By
acting as a financial intermediary, the Company is able to provide its customers
with access to a wide range of products from the securities, foreign exchange,
and derivatives markets. In acting for its own account, the Company may take
positions in some of these instruments with the objective of generating trading
profits. These activities expose the Company to two primary types of market
risk: interest rate and foreign currency exchange risk.
 
    In order to manage interest rate and foreign currency exchange risk
associated with its trading activities, the Company utilizes a variety of
non-statistical methods including: position limits for each trading activity,
daily marking of all positions to market, daily profit and loss statements,
position reports, and independent verification of all inventory pricing.
Additionally, the RMU reports positions and profits and losses daily to the
Treasurer and trading managers and weekly to the CFO. ALCO is provided reports
on a monthly basis. The Company believes that these procedures, which stress
timely communication between the RMU and senior management, are the most
important elements of the risk management process.
 
    The Company uses a form of Value at Risk (VaR) methodology to measure the
overall market risk inherent in its trading account activities. Under this
methodology, management statistically calculates, with 97.5 percent confidence,
the potential loss in fair value that the Company might experience if an adverse
 
                                      F-30
<PAGE>
shift in market prices were to occur within a period of 5 business days. The
amount of VaR is managed within limits well below the maximum limit established
by Board policy at 0.5% of shareholders' equity. The VaR model incorporates a
number of key assumptions, including assumed holding period and historical
volatility based on 3 years of historical market data updated quarterly.
 
    During 1997 the Company's foreign exchange trading VaR averaged $73 thousand
and peaked at $147 thousand. The low VaR was $32 thousand. Correspondingly, the
Company's securities trading VaR averaged $558 thousand and peaked at $717
thousand. The low VaR was $439 thousand.
 
    The Company's interest rate derivatives contracts include $2.4 billion of
derivative contracts entered into as an accommodation for customers. The Company
acts as an intermediary and matches these contracts at a profit with contracts
with BTM or other dealers, thus neutralizing the related market risk. The
Company maintains responsibility for the credit risk associated with these
contracts.
 
LIQUIDITY RISK
 
    Liquidity risk represents the potential for loss as a result of limitations
on 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 ALM Policy approved by the Board requires quarterly reviews of the
Company's liquidity by the ALCO, which is composed of bank senior executives.
The Company's liquidity draws upon the strength of its extensive retail and
commercial market business franchise, coupled with the ability to obtain funds
for various terms in a variety of domestic and international money markets.
Liquidity is managed through the funding and investment functions of the
Treasury Division.
 
    Core deposits provide the Company with a sizable source of relatively stable
and low-cost funds. The Company's average core deposits, which include demand
deposits, money market demand accounts, and savings and consumer time deposits,
combined with average common shareholder's equity, funded 61 percent of average
total assets of $29.7 billion for the year ended December 31, 1997. Most of the
remaining funding was provided by short-term borrowings in the form of
negotiable certificates of deposit, foreign deposits, federal funds purchased
and securities sold under repurchase agreements, commercial paper and other
borrowings.
 
    Liquidity may also be provided by the sale or maturity of assets. Such
assets include interest bearing deposits in banks, federal funds sold and
securities purchased under resale agreements, and trading account securities.
The aggregate of these assets averaged $1.8 billion during 1997. Additional
liquidity may be provided by investment securities available for sale which
amounted to $2.5 billion at December 31, 1997, and by loan maturities. At
December 31, 1997, $6.5 billion of loans were scheduled to mature within one
year.

(1)  Certain balance sheet classifications used for interest rate sensitivity
    analysis do not conform to the Consolidated Balance Sheets on F-35.
 
(2)  Items that neither reprice nor mature are included in the "After 5 years"
    column.
 
(3)  Interest rate sensitivity of non-maturity deposit accounts are based on
    assumptions for a declining interest rate scenario since the Company's
    balance sheet is asset-sensitive.
 
(4)  70 percent of the demand deposit account balance is assumed to be "core"
    deposits, which are not sensitive to interest rate changes.
 
(5)  Floors purchased affect interest rate sensitivity in a declining interest
    rate scenario.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                        DECEMBER 31, 1997, 1996 AND 1995
 
NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NATURE OF
       OPERATIONS
 
    UnionBanCal Corporation (the Company) is a commercial bank holding company,
82 percent owned by The Bank of Tokyo-Mitsubishi, Ltd. (BTM) and 18 percent
owned by other shareholders.
 
    On April 1, 1996, the Company was created by the combination of Union Bank
with BanCal Tri-State Corporation and its banking subsidiary, The Bank of
California, N.A. The combination was accounted for as a reorganization of
entities under common control (similar to a business combination under the
pooling of interests method). Accordingly, all historical financial information
has been restated as if the combination had been in effect for all periods
presented. The merger was effected by the issuance of 54.4 million shares of
Union Bank common stock in exchange for all the outstanding common shares of
BanCal Tri-State Corporation. Information pertaining to merger and integration
expense is presented in Note 7.
 
    On August 10, 1998, the Company exchanged 10.2 million shares of its common
stock for 7.2 million shares of Union Bank of California, N.A. (the Bank) common
stock owned directly by BTM. This share exchange provides the Company with a 100
percent ownership interest in the Bank. In addition, it increases BTM's
ownership percentage of the Company to 82 percent from 81 percent.
 
    The exchange of shares was accounted for as a reorganization of entities
under common control. Accordingly, amounts previously reported as Parent Direct
Interest in Bank Subsidiary, including the proportionate share of net income,
dividends, and other comprehensive income have been reclassified to combine them
with the corresponding amounts attributable to the Company's common shareholders
for all periods presented.
 
    On November 18, 1998, the Company's Board of Directors approved the
declaration of a 3-for-1 stock split effective for shareholders of record on
December 7, 1998. Accordingly, all historical financial information has been
restated as if the stock split had been in effect for all periods presented.
 
    The Company provides a wide range of financial services to consumers, small
businesses, middle market companies and major corporations, primarily in
California, Oregon and Washington, but also nationally and internationally.
 
    BASIS OF FINANCIAL STATEMENT PRESENTATION
 
    The accounting and reporting policies of the Company conform to generally
accepted accounting principles (GAAP) and general practice within the banking
industry. Those policies that materially affect the determination of financial
position, results of operations, and cash flows are summarized below.
 
    The Consolidated Financial Statements include the accounts of the Company.
All material intercompany transactions and balances have been eliminated. 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 revenues and expenses
during the reporting period. Actual results could differ from those estimates.
Certain amounts for prior periods have been reclassified to conform with current
financial statement presentation.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
                        DECEMBER 31, 1997, 1996 AND 1995
 
NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NATURE OF
       OPERATIONS (CONTINUED)
    CASH AND CASH EQUIVALENTS
 
    For purposes of reporting cash flows, cash and cash equivalents include cash
and due from banks, interest bearing deposits in banks and federal funds sold
and securities purchased under resale agreements, substantially all of which
have maturities less than 90 days.
 
    TRADING ACCOUNT ASSETS
 
    Trading account assets are those financial instruments that management
acquires with the intent to hold for short periods of time in order to take
advantage of anticipated changes in market values. Substantially all of these
assets are securities with a high degree of liquidity and a readily determinable
market value. Interest earned, paid or accrued, on trading account assets is
included in interest income using a method that generally produces a level
yield. Realized gains and losses from the close out of trading account positions
and unrealized market value adjustments are recognized in noninterest income.
 
    SECURITIES AVAILABLE FOR SALE AND SECURITIES HELD TO MATURITY
 
    The Company's securities portfolios consist of debt and equity securities
that are classified either as securities available for sale or securities held
to maturity.
 
    Debt securities for which the Company has the positive intent and ability to
hold until maturity are classified as securities held to maturity and carried at
amortized cost.
 
    Debt securities and equity securities with readily determinable market
values that are not classified as either held to maturity securities or trading
account assets are classified as securities available for sale and carried at
fair value, with the unrealized gains or losses reported net of taxes as a
separate component of shareholders' equity until realized.
 
    Realized gains and losses arising from the sale of securities are based upon
the specific identification method and included in noninterest income as
securities gains (losses), net.
 
    Interest income on debt securities includes the amortization of premiums and
the accretion of discounts using the effective interest method and is included
in interest income on securities. Dividend income on equity securities is
included in noninterest income.
 
    LOANS
 
    Loans are reported at the principal amounts outstanding, net of unamortized
nonrefundable loan fees and related direct loan origination costs. Deferred net
fees and costs are recognized in interest income over the loan term using a
method that generally produces a level yield on the unpaid loan balance.
Nonrefundable fees and direct loan origination costs related to loans held for
sale are deferred and recognized as a component of the gain or loss on sale.
Interest income is accrued principally on a simple interest basis.
 
    Nonaccrual loans are those for which management has discontinued accrual of

NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NATURE OF
       OPERATIONS (CONTINUED)
    Interest accruals are continued for certain small business loans that are
processed centrally, consumer loans, credit cards, and one-to-four family
residential real estate loans. These loans are charged off or written down to
their net realizable value based on delinquency time frames that range from 120
to 270 days, depending on the type of credit that has been extended. Interest
accruals are also continued for loans that are both well secured and in the
process of collection. For this purpose, loans are considered well secured if
they are collateralized by property having a net realizable value in excess of
the amount of principal and accrued interest outstanding or are guaranteed by a
financially responsible and willing party. Loans are considered "in the process
of collection" if collection is proceeding in due course either through legal
action or other actions that are reasonably expected to result in the prompt
repayment of the debt or in its restoration to current status.
 
    When a loan is placed on nonaccrual, all previously accrued but uncollected
interest is reversed against current period operating results. All subsequent
payments received are first applied to unpaid principal and then to uncollected
interest. Interest income is accrued at such time as the loan is brought fully
current as to both principal and interest, and, in management's judgment, such
loans are considered to be fully collectible. However, Company policy also
allows management to continue the recognition of interest income on certain
loans designated as nonaccrual. This portion of the nonaccrual portfolio is
referred to as "Cash Basis Nonaccrual" loans. This policy only applies to loans
that are well secured and in management's judgment are considered to be fully
collectible. Although the accrual of interest is suspended, any payments
received may be applied to the loan according to its contractual terms and
interest income recognized accordingly.
 
    Loans are considered impaired when, based on current information, it is
probable that the Company will be unable to collect all amounts due according to
the contractual terms of the loan agreement, including interest payments.
Impaired loans are carried at the lower of the recorded investment in the loan,
the estimated present value of total expected future cash flows, discounted at
the loan's effective rate, or the fair value of the collateral, if the loan is
collateral dependent. Additionally, some impaired loans with commitments of less
than $1 million are aggregated for the purpose of measuring impairment using
historical loss factors as a means of measurement. Excluded from the impairment
analysis are large groups of smaller balance homogeneous loans such as consumer
and residential mortgage loans.
 
    Renegotiated loans are those in which the Company has formally restructured
a significant portion of the loan. The remaining portion is normally charged
off, with a concession either in the form of below market rate financing, or
debt forgiveness on the charged off portion. Loans that have been renegotiated
and have not met specific performance standards for payment are classified as
renegotiated loans within the classification of nonperforming assets. Upon
payment performance, such loans may be transferred from nonperforming status to
accrual status.
 
    The Company offers two types of leases to customers: 1) direct financing
leases where the assets leased are acquired without additional financing from
other sources, and 2) leveraged leases where a substantial portion of the
financing is provided by debt with no recourse to the Company. Direct financing
leases are carried net of unearned income, unamortized nonrefundable fees and
related direct costs associated with the origination or purchase of leases.
Leveraged leases are carried net of nonrecourse debt.

                        DECEMBER 31, 1997, 1996 AND 1995
 
NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NATURE OF
       OPERATIONS (CONTINUED)
    ALLOWANCE FOR CREDIT LOSSES
 
    The Company's allowance for credit losses is maintained at a level
considered by management to be adequate to absorb estimated credit losses and
other credit-related charges. The allowance for credit losses is increased by
the provision for credit losses, which is charged against current period
operating results and decreased by the amount of credit losses, net of
recoveries. Losses are fully or partially charged against the allowance for
credit losses when, in management's judgment, the uncollectible portion of a
loan's principal balance is determined. While management has segmented the
allowance to various credit-related products, the allowance is general in nature
and is available for all extension of credits, including off-balance sheet
instruments.
 
    In evaluating the adequacy of the allowance for credit losses, management
estimates the amount of the potential risk of loss for each loan that has been
identified as having more than standard credit risk. Those estimates give
consideration to general economic conditions and their effects on the borrower's
industry, financial and management abilities and to current valuations of
collateral where appropriate. An estimate for potential credit loss content is
calculated for all loans not so identified based upon the risk characteristics
of particular categories of loans and historical loss experience in the
portfolio, adjusted, as appropriate, for the estimated effects of current
economic conditions. Further consideration for the allocation is based on credit
risk concentrations in the portfolio and commitments and contingent obligations
under off-balance sheet commercial and standby letters of credit. For analytical
purposes only, management attributes portions of the allowance for credit losses
to individual loans or groups of loans. Although the allowance for credit losses
is allocated to various portfolio segments, it is general in nature and is
available for the loan portfolio in its entirety. Although management believes
that the allowance for possible credit losses is adequate, future provisions
will be subject to continuing evaluation of inherent risk in the loan portfolio
and other credit exposures.
 
    A loan is considered impaired when management determines that it is probable
that the Company will be unable to collect all amounts due according to the
original contractual terms of the loan agreement. Impairment is measured by the
difference between the recorded investment in the loan (including accrued
interest, net deferred loan fees or costs and unamortized premium or discount)
and the estimated present value of total expected future cash flows, discounted
at the loan's effective rate, or the fair value of the collateral, if the loan
is collateral dependent. An impairment is recognized by adjusting an allocation
of the existing allowance for credit losses.
 
    PREMISES AND EQUIPMENT
 
    Premises and equipment are carried at cost, less accumulated depreciation
and amortization. Depreciation and amortization are calculated using the
straight-line method over the estimated useful life of each asset. Lives of
premises range from ten to forty years; lives of furniture and equipment range
from three to eight years. Leasehold improvements are amortized over the term of
the respective lease or 10 years, whichever is shorter.

NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NATURE OF
       OPERATIONS (CONTINUED)
    OTHER ASSETS
 
    Goodwill represents the excess of purchase price over the fair value of
identifiable net assets of acquired companies and is reported as intangible
assets. Goodwill is amortized using the straight-line method, generally over 15
years.
 
    Other real estate owned (OREO) represents the collateral acquired through
foreclosure in full or partial satisfaction of the related loan. OREO is
recorded at the lower of the loan's unpaid principal balance or its fair value
as established by a current appraisal, adjusted for disposition costs. Any
writedown at the date of transfer is charged to the allowance for credit losses.
On an ongoing basis, OREO values, recorded in other assets, are reviewed
annually and any decline in value is recognized as foreclosed asset expense in
the current period. The net operating results from these assets are included in
the current period in noninterest expense as foreclosed asset expense (income).
 
    DERIVATIVE INSTRUMENTS HELD FOR TRADING OR CUSTOMER ACCOMMODATION
 
    The Company enters into a variety of interest rate derivative contracts,
primarily swaps and options and foreign exchange contracts, which include spot,
futures, forward, swap and option positions either for trading purposes, based
on management's intent at inception, or as an accommodation to customers.
 
    Derivatives held or issued for trading or customer accommodation are carried
at fair value, with realized and unrealized changes in fair values on contracts
included in noninterest income in the period in which the changes occur.
Unrealized gains and losses are reported gross and included in trading account
assets and other liabilities, respectively. Cash flows are reported net as
operating activities.
 
    DERIVATIVE INSTRUMENTS HELD FOR PURPOSES OTHER THAN TRADING
 
    The Company enters into a variety of derivative contracts as a means of
reducing the Company's interest rate and foreign exchange exposures. At
inception these contracts are evaluated in order to determine if they qualify
for hedge accounting treatment and are accounted for either on a deferral,
accrual or market value basis, depending on the nature of the Company's hedge
strategy and the method used to account for the hedged item. Hedge criteria
include demonstrating the manner in which the hedge will reduce risk,
identifying the specific asset, liability or firm commitment being hedged, and
citing the time horizon being hedged. A monthly evaluation is performed to
ensure that continuing correlation exists between the hedge and the item being
hedged.
 
    Net interest settlements on interest rate swap, cap and floor agreements are
recognized on an accrual basis as interest income or expense of the related
asset or liability over the lives of the agreements. Premiums paid or received
for interest rate caps and floors are amortized either to interest income or to
expense of the related asset or liability over the lives of the agreements. If
an agreement is terminated early, any resulting gain or loss is deferred and
amortized as interest income or expense of the related asset or liability over
the remaining life of the original agreement. Net settlement amounts are
reported gross as other assets and other liabilities. Cash flows are reported
net as operating activities.

NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NATURE OF
       OPERATIONS (CONTINUED)
    FOREIGN CURRENCY TRANSLATION
 
    Assets, liabilities and results of operations for foreign branches are
recorded based on the functional currency of each branch. Since the functional
currency of the branches is the local currency, the net assets are remeasured
into U.S. dollars using a combination of current and historical exchange rates.
The resulting gains or losses are included in shareholders' equity, on a net of
tax basis.
 
    TRANSFERS AND SERVICING OF FINANCIAL ASSETS AND EXTINGUISHMENT OF
     LIABILITIES
 
    On January 1, 1997, the Company adopted Statement of Financial Accounting
Standards (SFAS) No. 125, "Accounting for Transfers and Servicing of Financial
Assets and Extinguishments of Liabilities". The 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 occurring after December 31, 1996 and has been applied
prospectively. Certain provisions of SFAS No. 125 have been postponed under SFAS
No. 127, "Deferral of the Effective Date of Certain Provisions of FASB Statement
No. 125". Also see "PENDING ACCOUNTING PRONOUNCEMENTS".
 
    INCOME TAXES
 
    The Company files consolidated federal and combined state income tax
returns. Amounts provided for income tax expense are based on income reported
for financial statement purposes and do not necessarily represent amounts
currently payable under tax laws. Deferred taxes, which arise principally from
temporary differences between the period in which certain income and expenses
are recognized for financial accounting purposes and the period in which they
affect taxable income, are included in the amounts provided for income taxes.
Under this method, the computation of the net deferred tax liability or asset
gives current recognition to changes in the tax laws.
 
    NET INCOME PER COMMON SHARE
 
    Basic earnings per share (EPS) is computed by dividing net income after
preferred dividends by the weighted average number of common shares outstanding
during the period. Diluted EPS incorporates the dilutive effect of common stock
equivalents outstanding on an average basis during the period. Stock options
(see Note 12) are a common stock equivalent.
 
    The Company adopted the provisions of SFAS No. 128, "Earnings per Share",
for the year ended December 31, 1997. As required by the provisions of the
Statement, all prior period and interim period EPS data presented have been
restated. This Statement simplifies the standards for computing 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. Also see Note 17.

       OPERATIONS (CONTINUED)
    COMPREHENSIVE INCOME
 
    The Company has retroactively adopted SFAS No. 130, "Reporting Comprehensive
Income", which requires that an enterprise report and display, by major
components and as a single total, the change in its net assets during the period
from non-owner sources. The adoption of this Statement resulted in a change in
the financial statement presentation, but did not have an impact on the
Company's consolidated financial position, results of operations or cash flows.
 
    EMPLOYEE BENEFIT AND INCENTIVE PLANS AND OTHER POSTRETIREMENT BENEFITS
 
    The Company provides a variety of benefit and incentive compensation plans
for eligible employees and retirees. Provisions for the costs of these employee
benefit and incentive plans and postretirement benefit plans are accrued and
charged to expense when the benefit is earned.
 
    STOCK-BASED COMPENSATION
 
    The Company adopted the disclosure provisions of SFAS No. 123, "Accounting
for Stock-Based Compensation", on January 1, 1996. SFAS No. 123 establishes
accounting and disclosure requirements using a fair value-based method of
accounting for stock-based compensation plans.
 
    As allowed under the provisions of SFAS No. 123, the Company has chosen to
continue to recognize compensation expense using the intrinsic value-based
method of valuing stock options prescribed in Accounting Principles Board
Opinion No. 25, "Accounting for Stock Issued to Employees" and related
Interpretations. Under the intrinsic value-based method, compensation cost is
measured as the amount by which the quoted market price of the Company's stock
at the date of grant exceeds the stock option exercise price.
 
    Compensation cost associated with the Company's unvested restricted stock
issued under the management stock plan is measured based on the market price of
the stock at the grant date and is expensed over the vesting period.
 
    PENDING ACCOUNTING PRONOUNCEMENTS
 
    In December 1996, the Financial Accounting Standards Board (FASB) issued
SFAS No. 127, "Deferral of the Effective Date of Certain Provisions of FASB
Statement No. 125", which defers the implementation of SFAS No. 125 for
transactions related to repurchase agreements, dollar-roll repurchase
agreements, securities lending and similar transactions until January 1, 1998.
Management believes that the effect of adoption of SFAS No. 125, for those
transactions covered under SFAS No. 127, on the Company's Consolidated Financial
Statements will not be material.
 
    In June 1997, the FASB issued SFAS 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 this Statement 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. The Statement is effective with the
year-end 1998 financial statements.

NOTE 3 -- LOANS AND ALLOWANCE FOR CREDIT LOSSES (CONTINUED)
    LOAN IMPAIRMENT
 
    Impaired loans of the Company include commercial, financial and industrial,
construction and commercial mortgage loans designated as nonaccrual. When the
value of an impaired loan is less than the recorded investment in the loan, a
portion of the Company's allowance for credit losses is allocated as an
impairment allowance.
 
    Effective January 1, 1995, the Company's policy for recognition of interest
income, charge-offs of loans, and application of payments on impaired loans is
the same as the policy applied to nonaccrual loans.
 
    The following table sets forth information about the Company's impaired
loans at the dates indicated.

(1)  These loans do not require an allowance for credit losses since the fair
    values of the impaired loans equal or exceed the recorded investments in the
    loans.
 
(2)  This amount was evaluated for impairment using three measurement methods as
    follows: $27 million, $38 million, and $64 million was evaluated using the
    present value of the expected future cash flows at December 31, 1997, 1996
    and 1995, respectively; $53 million, $45 million, and $95 million was
    evaluated using the fair value of the collateral at December 31, 1997, 1996
    and 1995, respectively; and $28 million, $31 million, and $14 million was
    evaluated using historical loss factors at December 31, 1997, 1996 and 1995,
    respectively.
 
    RELATED PARTY LOANS
 
    The Company in some cases makes loans to related parties including its
directors, executive officers and their affiliated companies. At December 31,
1997, related party loans outstanding to individuals who served as directors or
executive officers at anytime during the year totaled $38 million as compared to
$79 million at December 31, 1996. In the opinion of management, these related
party loans were made on substantially the same terms, including interest rates
and collateral requirements, as those terms prevailing at the date these loans
were made. During 1997 and 1996, there were no loans to related parties which
were charged off. Additionally, at December 31, 1997 and 1996, there were no
loans to related parties which were nonperforming.

NOTE 6 -- EMPLOYEE BENEFIT AND INCENTIVE PLANS AND OTHER POSTRETIREMENT BENEFITS
 
    RETIREMENT PLANS
 
    Between April 1, 1996 and December 31, 1996, the Company maintained two
retirement plans, one covering former Union Bank employees and the other
covering former BanCal Tri-State Corporation employees. Effective January 1,
1997, the Union Bank Retirement Plan was amended and renamed the Union Bank of
California, N.A. Retirement Plan (the Plan). In addition, the plan covering
former BanCal Tri-State Corporation employees was terminated and all account
balances became fully vested. Employees of the former BanCal Tri-State
Corporation entered the Plan on January 1, 1997.
 
    The Plan is a noncontributory defined benefit plan that provides retirement
benefits based on years of credited service and the final average compensation
amount, as defined in the Plan. Employees become eligible for this plan after
one year of service and become fully vested after five years of service. Prior
Bank of California participants received credited service from date of hire for
vesting, eligibility and early retirement purposes, but only received service
from January 1, 1997 for benefit purposes. The Company's funding policy is to
make contributions equal to the maximum deductible amount as allowed by the
Internal Revenue Code. Contributions are intended to provide not only for
benefits attributed to services to date, but also for those expected to be
earned in the future. Plan assets are invested in U.S. government securities,
corporate bonds, and commingled investment funds.

    The former BanCal Tri-State Corporation retirement plan, which was
terminated effective January 1, 1997, was a defined contribution plan. The
Company's expense for pension contributions for the years ended December 31,
1996 and 1995 was $5 million and $6 million, respectively.
 
    EXECUTIVE SUPPLEMENTAL BENEFIT PLANS
 
    The Company has several Executive Supplemental Benefit Plans (ESBP) which
provide eligible employees with supplemental retirement benefits. The plans are
unfunded. The accrued liability for ESBP's included in other liabilities in the
Consolidated Balance Sheets was $39 million at December 31, 1997 and $35 million
at December 31, 1996. The Company's expense relating to the ESBP's was $4
million for each of the years ended December 31, 1997 and 1996 and $3 million
for the year ended December 31, 1995.
 
    SECTION 401(K) SAVINGS PLANS
 
    The Company has a defined contribution plan authorized under Section 401(k)
of the Internal Revenue Code. All benefits-eligible employees with at least one
year of service are eligible to participate in the plan. Employees may
contribute up to 16 percent of their pre-tax covered compensation or up to 10
percent of their after-tax covered compensation through salary deductions. The
Company contributes 50 percent of every pre-tax dollar an employee contributes
up to the first 6 percent of the employee's pre-tax covered compensation.
Effective January 1, 1997, employees are fully vested in the employer's
contributions immediately. In addition, the Company may make a discretionary
annual profit-sharing contribution up to 2.5 percent of an employee's pay. This
profit-sharing contribution is for all eligible employees, regardless of whether
an employee is participating in the 401(k) plan, and depends on the Bank's
annual financial performance. All employer contributions are tax deductible by
the Company. The Company's combined matching contribution expense was $13
million, $9 million and $9 million for the years ended December 31, 1997, 1996
and 1995, respectively.

    OTHER POSTRETIREMENT BENEFITS
 
    The Company provides certain health care and life insurance benefits for its
retired employees. The health care cost is shared between the Company and the
retiree. The life insurance plan is noncontributory. The accounting for the
health care plan anticipates future cost-sharing changes to the written plan
that are consistent with the Company's intent to maintain a level of
cost-sharing at approximately 25 percent. Assets set aside to cover such
obligations are primarily invested in mutual funds.
 
    The following table sets forth the plan's combined funded status recognized.

    The unrecognized transition obligation recorded on January 1, 1993 is being
amortized over 20 years.
 
    For 1997, the Company assumed a 9 percent annual rate of increase in the per
capita cost of postretirement medical benefits for the indemnity plan and a 4
percent annual rate of increase was assumed for the health maintenance
organization (HMO) plan. For future periods, the rate for the indemnity plan was
expected to gradually decrease from 9 percent to 5.5 percent in 2007 and remain

that level thereafter. The rate for the HMO plan was expected to increase after
one year of being at a low rate and then gradually decrease to 5.5 percent in
the year 2007 and thereafter.
 
    The healthcare cost trend rate assumption has a significant effect on the
amounts reported. To illustrate, increasing the assumed health care cost trend
rates by one percentage point in each year would increase the accumulated
postretirement benefit obligation as of December 31, 1997 by $11 million and the
aggregate of the service and interest cost components of net periodic
postretirement benefit cost for the year then ended by $1 million.
 
    For 1996, the Company assumed a 9 percent annual rate of increase in the per
capita cost of postretirement medical benefits for the indemnity plan and a 4
percent annual rate of increase was assumed for the HMO plan. For future periods
the assumed rate for the indemnity plan gradually decreased from 9 percent to
5.5 percent in 2007 and remained level thereafter. The assumed rate of change on
the HMO plan increased to 7 percent in 1997 and then gradually decreased to 5.5
percent in the year 2007 and thereafter.
 
    For 1995, the former Union Bank assumed a 9 percent annual rate of increase
in the per capita cost of postretirement medical benefits for the indemnity plan
and a 4 percent annual rate of increase was assumed for the HMO plan. For future
periods the assumed rate for the indemnity plan gradually decreased from 9
percent to 5.5 percent in 2007 and remained level thereafter. The assumed rate
of change on the HMO plan increased for the remainder of the decade, then
gradually decreased to 5.5 percent in the year 2007 and thereafter.
 
    For 1995, former BanCal Tri-State Corporation assumed an 11.5 percent annual
rate of increase in the per capita cost of postretirement medical benefits for
the indemnity plan. For future periods, the assumed rate for the indemnity plan
gradually decreased from 11.5 percent to 5.5 percent in 2003 and remained level
thereafter.
 
    The discount rate used in determining the actuarial present value of the
accumulated postretirement benefit obligation was 7.00% as of December 31, 1997
and 7.50% as of December 31, 1996 and 1995. The estimated rate of return on plan
assets was 8.00% as of December 31, 1997, 1996 and 1995.

    During 1997 the Company received a refund from the State of California
Franchise Tax Board of approximately $25 million (net of federal taxes of $17
million) in settlement of litigation, administration and audit disputes covering
the years 1975-1987. The refund was recorded as a reduction to state income tax
expense.
 
    Federal and state tax returns for several years are under or subject to
examination by the respective taxing authorities. Although the ultimate outcome
of such examinations cannot be determined at this time, management believes that
the resolution of issues that have been or may be raised will not have a
material adverse effect on the Company's consolidated financial position or
results of operations.

Federal Reserve guidelines for assessing regulatory capital. For the total
risk-based capital ratio, the amount of notes which qualify as capital is
reduced as the notes approach maturity. At December 31, 1997 and 1996, $239
million and $219 million, respectively, of the notes qualified as risk-based
capital.
 
    Provisions of several of the notes restrict the use of the Company's

indebtedness, distributions to shareholders, mergers, sales of certain assets,
transactions with affiliates and changes in majority stock ownership of the
Company.

unpaid dividends to the redemption date. The redemption was funded by proceeds
from the issuance of $200 million in subordinated capital notes in June 1997.
 
NOTE 11 -- DIVIDEND REINVESTMENT AND STOCK PURCHASE PLAN
 
    The Company has a dividend reinvestment and stock purchase plan for
shareholders. The plan allows shareholders to automatically reinvest all or part
of their dividends in additional shares of the Company's common stock at a cost
of 5 percent below the market price. Participating shareholders also have the
option of purchasing additional shares at the full market price with cash
payments of $25 to $3,000 per quarter. The Company obtains shares required for
reinvestment through open market purchases or by the issuance of new shares from
its authorized but unissued stock. During 1997, 1996 and 1995, 131,127; 155,724
and, 1,862,034 shares, respectively, were required for dividend reinvestment
purposes, of which 3,687; 71,706 and, 1,862,034 shares were considered new
issuances during 1997, 1996 and 1995, respectively. BTM discontinued its
participation in the plan after the quarter ended March 31, 1995 and did not
participate in the plan as of December 31, 1997.
 
NOTE 12 -- MANAGEMENT STOCK PLAN
 
    The Company has a management stock plan (the Stock Plan) which has 6,600,000
shares of the Company's common stock authorized to be awarded to key employees
and outside directors of the Company and its subsidiaries at the discretion of
the Executive Compensation and Benefits Committee of the Board of Directors (the
Committee). The combined number of shares that are granted under the Stock Plan
cannot exceed 6,600,000 shares of the Company's common stock. Committee members
and employees on rotational assignment from BTM are not eligible for stock
awards.
 
    The Committee determines the term of each stock option grant, up to a
maximum of ten years from the date of grant. The exercise price of the options
issued under the Stock Plan shall not be less than the fair market value on the
date the option is granted. Unvested restricted stock issued under the Stock
Plan is shown as a reduction to retained earnings. The value of the restricted
shares at the date of grant is amortized to compensation expense over its
vesting period. All cancelled or forfeited options and restricted stock become
available for future grants.
 
    In 1997, 1996 and 1995, the Company granted options to various key
employees, including principal officers, under the Stock Plan. The stock options
vest pro rata on each anniversary of the grant date and become fully exercisable
three years from the grant date, provided that the employee has completed the
specified continuous service requirement. They vest earlier if the employee
dies, is permanently and totally disabled, or retires under certain grant, age
and service conditions.

    In 1997, 1996 and 1995, the Company also granted 178,320; 133,440 and,
231,210 shares, respectively, of restricted stock to key officers, including
executive officers, under the Stock Plan. The awards of restricted stock vest
pro rata on each anniversary of the grant date and become fully vested four
years from the grant date, provided that the employee has completed the
specified continuous service requirement. They vest earlier if the employee
dies, is permanently and totally disabled, or retires under certain grant, age
and service conditions. Restricted shareholders have the right to vote their
restricted shares and receive dividends.

    At December 31, 1997, 1996 and 1995, 3,365,586, 958,383 and 1,342,449
shares, respectively, were available for future grants as either stock options
or restricted stock under the Stock Plan.
 
    The Company follows the intrinsic value based method in accounting for its
employee stock-based compensation plan. Accordingly, no compensation cost has
been recognized for its stock option grants. Had compensation cost for the
Company's stock-based plan been determined based on the fair value at the grant
dates for awards under that plan consistent with the method of SFAS No. 123,
"Accounting for Stock-Based Compensation", the Company's net income and net
income per share would have decreased to the pro forma amounts indicated in the
following table. Options that were granted prior to January 1, 1995 with vesting
periods in 1995 and later are excluded from the pro forma results indicated for
1996 and 1995 in the following table.

NOTE 12 -- MANAGEMENT STOCK PLAN (CONTINUED)
1995: risk-free interest rates of 6.6% in 1997, 6.3% in 1996 and 7.1% in 1995;
expected volatility of 26% in 1997, 28% in 1996 and 28% in 1995; expected lives
of 6, 7 and 7 years for 1997, 1996 and 1995, respectively, and expected dividend
yields of 2.1% in 1997, 2.6% in 1996 and 4.2% in 1995.
 
    Effective January 1, 1997, the Company established a Performance Share Plan.
Eligible participants may earn performance share awards to be redeemed in cash
three years after the date of grant. Performance shares are linked to
shareholder value in two ways: (1) the market price of the Company's common
stock, and (2) return on assets, a performance measure closely linked to value
creation. Eligible participants generally receive grants of performance shares
annually. The total number of performance shares granted under the plan cannot
exceed 600,000 and in 1997 the Company granted 14,400 shares. The value of a
performance share is equal to the market price of the Company's common stock.
All cancelled or forfeited performance shares become available for future
grants.
 
NOTE 13 -- FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The fair value of a financial instrument is the amount at which the
instrument could be exchanged in a current transaction between willing parties,
other than in a forced or liquidation sale. All of the fair values presented
below have been made under this definition of fair value unless otherwise
disclosed.
 
    It is management's belief that the fair values presented below are
reasonable based on the valuation techniques and data available to the Company
as of December 31, 1997 and 1996, as more fully described below. It should be
noted that the operations of the Company are managed on a going concern basis
and not a liquidation basis. As a result, the ultimate value realized for the
financial instruments presented could be substantially different when actually
recognized over time through the normal course of operations. Additionally, a
substantial portion of an institution's inherent value is its capitalization and
franchise value. Neither of these components have been given consideration in
the presentation of fair values which follow.

    The Company is also a party to financial instruments that are not reflected
on the balance sheet but represent obligations of the Company in the normal
course of business. For information regarding the fair value of off-balance
sheet financial instruments, see Note 14.
 
    The following methods and assumptions were used to estimate fair value of
each class of financial instruments for which it is practicable to estimate that
value.
 
    CASH AND CASH EQUIVALENTS:  The book value of cash and cash equivalents is
considered a reasonable estimate of fair value.
 
    TRADING ACCOUNT ASSETS:  Trading account assets are short term in nature and
valued at market based on quoted market prices or dealer quotes. If a quoted
market price is not available, the recorded amounts are estimated using quoted
market prices for similar securities. Thus, carrying value is considered a
reasonable estimate of fair value for these financial instruments.
 
    SECURITIES:  The fair value of securities is based on quoted market prices
or dealer quotes. If a quoted market price is not available, fair value is
estimated using quoted market prices for similar securities. Available for sale
securities are carried at their aggregate fair value, while held to maturity
securities are carried at amortized cost.
 
    LOANS:  The fair value for performing fixed and non-reference rate loans was
estimated by discounting the future cash flows using the current rates at which
similar loans would be made to borrowers with similar credit ratings and for
similar remaining maturities and where available, discount rates were based on
current market rates.

                        DECEMBER 31, 1997, 1996 AND 1995
 
NOTE 13 -- FAIR VALUE OF FINANCIAL INSTRUMENTS (CONTINUED)
    The fair value of performing loans tied to the Company's reference rate with
normal credit risk is assumed to approximate their book value. The fair value
for these floating rate loans with increasing credit risk was estimated by
calculating their present value using a yield the Company would currently
require for loans with similar terms to borrowers with similar credit quality.
 
    Loans which are on nonaccrual status were not included in the loan valuation
methods discussed previously. The fair value of these assets was estimated
assuming these loans were sold on a liquidation basis.
 
    The fair value of performing mortgage loans was based on quoted market
prices for loans with similar credit and interest rate risk characteristics.
 
    The fair value of performing credit card loans and credit lines is assumed
to approximate their book value. The fair value was estimated for credit card
loans and credit lines which were past due at December 31, 1997 and 1996 by
segregating them according to their past due status and then discounting them
based on the Company's historical probability of loss.
 
    NONINTEREST BEARING DEPOSITS:  The fair value of noninterest bearing
deposits is the amount payable on demand at the reporting date. The fair value
of the demand deposit intangible has not been estimated.
 
    INTEREST BEARING DEPOSITS:  The fair value of savings accounts and certain
money market accounts is the amount payable on demand at the reporting date. The
fair value of fixed maturity certificates of deposit was estimated using rates
currently being offered on certificates with similar maturities.
 
    BORROWED FUNDS:  The book values of federal funds purchased, securities sold
under repurchase agreements and other short-term borrowings are assumed to
approximate their fair value due to their limited duration characteristics. The
fair value for commercial paper and term federal funds purchased was estimated
using market quotes.
 
    SUBORDINATED CAPITAL NOTES:  The fair value of fixed-rate subordinated
capital notes was estimated using discounted cash flows based on market rates
for A-rated bank borrowings. The book values for variable-rate subordinated
capital notes are assumed to approximate fair market value.
 
NOTE 14 -- DERIVATIVE INSTRUMENTS AND OTHER FINANCIAL INSTRUMENTS WITH
        OFF-BALANCE SHEET RISK
 
    The Company is a party to certain derivative and other financial instruments
that are not reflected on the balance sheet but represent obligations or assets
of the Company in the normal course of business. These financial instruments are
used for trading activities of the Company, to meet the needs of customers and
to reduce the impact on the Company's operating results due to market
fluctuations in currency or interest rates.
 
    These financial instruments involve, to varying degrees, elements of credit
and market risk which are not recognized on the balance sheet. Credit risk is
defined as the possibility that a loss may occur from the failure of another
party to perform in accordance with the terms of the contract which exceeds the
value of the existing collateral, if any. Market risk is the possibility that
future changes in market conditions may make the financial instrument less
valuable.

NOTE 14 -- DERIVATIVE INSTRUMENTS AND OTHER FINANCIAL INSTRUMENTS WITH
        OFF-BALANCE SHEET RISK (CONTINUED)
 
  DERIVATIVE INSTRUMENTS
 
    The fair value of the derivative financial instruments was calculated based
on quoted market prices where available or if quoted market prices were not
available, the Company used the estimated amount it would receive or pay to
offset or terminate the agreements at December 31, 1997 based upon the terms of
such contracts relative to prevailing interest rates.
 
  TRADING ACTIVITIES IN DERIVATIVE INSTRUMENTS
 
    The following table reflects the Company's positions relating to trading
activities in derivative instruments. Trading activities include both activities
for the Company's own account and for customers. At December 31, 1997 and 1996,
the majority of the Company's derivative transactions for customers are hedged
with essentially offsetting contracts with other counterparties. The average
fair value of derivatives held or written for trading purposes during the year
is not significant. The notional amount of derivative instruments reflects the
extent of the Company's involvement in these instruments. For interest rate
swap, cap and floor agreements, notional amounts do not represent exposure to
credit or market risk. Notional amounts are not exchanged, but serve as a point
of reference for calculating payments.
 
    The following is a summary of derivative instruments held or written for
trading purposes.

  ASSET AND LIABILITY MANAGEMENT DERIVATIVE INSTRUMENTS
 
    Derivative positions are integral components of the Company's designated
asset and liability management activities. Therefore, the Company does not
believe it is meaningful to separately analyze the derivatives component of its
risk management activities in isolation from related positions. The Company uses
interest rate derivative instruments as part of its management of asset and
liability positions. Derivatives are used to manage interest rate risk relating
to specified groups of assets and liabilities, including LIBOR based commercial
loans, deposit liabilities and certain subordinated capital notes. The Company
uses foreign currency forward contracts as a means of managing foreign exchange
rate risk associated with assets or liabilities denominated in foreign
currencies.
 
    The following table reflects summary information on derivative contracts
used to hedge or modify the Company's risk as of December 31, 1997 and 1996.
Amounts included in the fair value column do not include gains or losses from
changes in the value of the underlying asset or liability being hedged. Notional
amounts are not exchanged, but serve as a point of reference for calculating
payments. For interest rate swap, cap and floor agreements, notional amounts do
not represent exposure to credit or market risk.

NOTE 14 -- DERIVATIVE INSTRUMENTS AND OTHER FINANCIAL INSTRUMENTS WITH
        OFF-BALANCE SHEET RISK (CONTINUED)
  OTHER FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK
 
    Commitments to extend credit are legally binding agreements to lend to a
customer provided there are no violations of any condition established in the
contract. Commitments have fixed expiration dates or other termination clauses
and may require payment of a fee or maintenance of compensatory balances. Such
fees are deferred and, upon partial or full exercise of the commitment,
amortized over the life of the loan or, if exercise is deemed remote, amortized
over the commitment period. Since many of the commitments are expected to expire
without being drawn upon, the contractual amounts do not necessarily represent
future cash requirements. With respect to commitments to extend credit and
letters of credit, the Company's exposure to credit risk in the event of
nonperformance by customers is represented by the contractual amount of those
instruments.
 
    Standby letters of credit are provided to customers to assure their
performance to a third party, generally in the production of goods and services
or under contractual commitments in the financial markets. Commercial letters of
credit are issued to customers to facilitate foreign or domestic trade
transactions. The Company charges fees for the issuance of standby and
commercial letters of credit. The majority of these type of commitments have
terms of one year or less and any fees charged are recognized as noninterest
income upon extension of the commitment. The credit risk involved in issuing
letters of credit is essentially the same as that involved in extending loan
facilities to customers and is represented by the contractual amount of those
instruments. When deemed necessary, the Company holds appropriate collateral
supporting those commitments. Management does not anticipate any material losses
as a result of these transactions.
 
    The Company uses the same credit underwriting policies in granting or
accepting such commitments or contingent obligations as it does for on-balance
sheet instruments, by evaluating customers' credit-worthiness. The amount of
collateral obtained, if deemed necessary by the Company upon extension of
credit, is based on management's evaluation of the customer. The nature of the
collateral varies but may include deposits held in financial institutions,
marketable securities, accounts receivable, inventory, property, equipment and
real estate. The Company also provides for potential losses from either
commitments to extend credit or standby letters of credit as a component of its
evaluation in determination of the adequacy of its allowance for credit losses
and resulting level of provision charged against current period earnings.
 
    The Company's pricing of these financial instruments is based on the credit
quality and other covenants or requirements. Management believes that the
current fees assessed on these off-balance sheet items represent market rates
which would be charged for similar agreements. Based on this belief, the Company
feels that the carrying amounts are reasonable estimates of the fair value of
these financial instruments. At December 31, 1997 and 1996, fair value
represents management's estimate of the

    The Company conducts securities lending transactions for institutional
customers as a fully disclosed agent, and, at times, indemnifies its customers
against counterparty default. All lending transactions are collateralized,
primarily by cash. The amount of securities lent with indemnification was $1,268
million and $1,170 million at December 31, 1997 and 1996, respectively. The
market value of the associated collateral was $1,294 million and $1,195 million
at December 31, 1997 and 1996, respectively.
 
NOTE 15 -- RESTRICTIONS ON CASH AND DUE FROM BANKS, SECURITIES, LOANS AND
        DIVIDENDS
 
    Federal Reserve Board regulations require the Bank to maintain reserve
balances based on the types and amounts of deposits received. Average reserve
balances were approximately $339 million and $291 million for the years ended
December 31, 1997 and 1996, respectively.
 
    As of December 31, 1997 and 1996, securities carried at $1.7 billion for
each of the years, and loans of $2.7 billion and $1.8 billion, respectively,
were pledged as collateral for borrowings, to secure public and trust department
deposits, and for repurchase agreements as required by contract or law.
 
    The Federal Reserve Act restricts the extension of credit by the Bank to BTM
and affiliates and to UnionBanCal Corporation and its non-bank subsidiaries and
requires that such loans be secured by certain types of collateral. At December
31, 1997, such extensions of credit were not material.
 
    The payment of dividends by the Bank to UnionBanCal Corporation is subject
to the approval of the Office of the Comptroller of the Currency (OCC) if the
total of all dividends declared in any calendar year exceeds certain calculated
amounts. The payment of dividends is also limited by minimum capital
requirements imposed on national banks by the OCC. At December 31, 1997, the
Bank could have declared dividends aggregating $170 million without prior
regulatory approval.
 
NOTE 16 -- REGULATORY CAPITAL REQUIREMENTS
 
    The Company and the Bank are subject to various regulatory capital
requirements administered by the federal banking agencies, including minimum
capital requirements. Failure to meet minimum capital requirements can initiate
certain mandatory, and possibly additional discretionary, actions by regulators
that, if undertaken, could have a direct material effect on the Company's
Consolidated Financial Statements. Under capital adequacy guidelines and the
regulatory framework for prompt corrective action, the Company and the Bank must
meet specific capital guidelines that involve quantitative measures of the

NOTE 16 -- REGULATORY CAPITAL REQUIREMENTS (CONTINUED)
Company's and Bank's assets, liabilities, and certain off-balance sheet items as
calculated under regulatory accounting practices. The Company's and the Bank's
capital amounts and the Bank's prompt corrective action classification are also
subject to qualitative judgments by the regulators about components, risk
weightings and other factors.
    Quantitative measures established by regulation to ensure capital adequacy
require the Company and the Bank to maintain minimum amounts and ratios (set
forth in the table below) of total and Tier 1 capital (as defined in the
regulations) to risk-weighted assets (as defined) and of Tier 1 capital (as
defined) to average assets (as defined). Management believes, as of December 31,
1997, that the Company and the Bank meet all capital adequacy requirements to
which they are subject.
    As of December 31, 1997 and 1996, the most recent notification from the OCC
categorized the Bank as "well capitalized" under the regulatory framework for
prompt corrective action. To be categorized as "well capitalized", the Bank must
maintain minimum total risk-based, Tier 1 risk-based and Tier 1 leverage ratios
as set forth in the table. There are no conditions or events since that
notification that management believes have changed the Bank's category.
    The Company's and the Bank's capital amounts and ratios are presented in the
following tables.

NOTE 19 -- CONTINGENCIES
 
    The Company is subject to various pending and threatened legal actions which
arise in the normal course of business. The Company maintains reserves for
losses from legal actions which are both probable and estimable. In the opinion
of management, the disposition of claims currently pending will not have a
material adverse effect on the Company's financial position or results of
operations.
 
NOTE 20 -- TRANSACTIONS WITH AFFILIATES
 
    The Company has had, and expects to have in the future, banking transactions
and other transactions in the ordinary course of business with BTM and with its
affiliates and associates. During the years ended December 31, 1997, 1996 and
1995, such transactions included, but were not limited to, origination,
participation, servicing and remarketing of loans and leases, purchase and sale
of acceptances and interest rate derivatives, foreign exchange transactions,
funds transfers, custodianships, electronic data processing, investment advice
and management, deposits and credit examination, and trust services. In the
opinion of management, such transactions were made at prevailing rates, terms
and conditions and do not involve more than the normal risk of collectibility or
present other unfavorable features. In addition, some compensation for services
rendered to the Company is paid to the expatriate officers from BTM, and
reimbursed by the Company to BTM under a services agreement.

                              MANAGEMENT STATEMENT
 
The management of UnionBanCal Corporation (the Company) is responsible for the
preparation, integrity, and fair presentation of its published financial
statements and all other information presented in this annual report. The
financial statements have been prepared in accordance with generally accepted
accounting principles and, as such, include amounts based on informed judgments
and estimates made by management.
 
    The Company maintains a system of internal accounting controls to provide
reasonable assurance that assets are safeguarded and that transactions are
executed in accordance with management's authorization and recorded properly to
permit the preparation of financial statements in accordance with generally
accepted accounting principles. Management recognizes that even a highly
effective internal control system has inherent risks, including the possibility
of human error and the circumvention or overriding of controls, and that the
effectiveness of an internal control system can change with circumstances.
However, management believes that the internal control system provides
reasonable assurance that errors or irregularities that could be material to the
financial statements would be prevented or detected on a timely basis and
corrected through the normal course of business. As of December 31, 1997,
management believes that the internal controls are in place and operating
effectively.
 
    The Audit and Examining Committee of the Board of Directors is comprised
entirely of outside directors who are independent of the Company's management;
it includes members with banking or related financial management expertise and
who are not large customers of the Bank. The Audit and Examining Committee has
access to outside counsel. The Audit and Examining Committee is responsible for
recommending to the Board of Directors the selection of independent auditors. It
meets periodically with management, the independent auditors, and the internal
auditors to ensure that they are carrying out their responsibilities. The Audit
and Examining Committee is also responsible for performing an oversight role by
reviewing and monitoring the financial, accounting and auditing procedures of
the Company in addition to reviewing the Company's financial reports. The
independent auditors and internal auditors have full and free access to the
Audit and Examining Committee, with or without the presence of management, to
discuss the adequacy of the internal control structure for financial reporting
and any other matters which they believe should be brought to the attention of
the Audit and Examining Committee.
 
    The financial statements have been audited by Deloitte & Touche LLP,
independent auditors, who were given unrestricted access to all financial
records and related data, including minutes of all meetings of shareholders, the
Board of Directors and committees of the Board. Management believes that all
representations made to the independent auditors during their audit were valid
and appropriate. The independent auditors' report is presented on Page F-78.

                          INDEPENDENT AUDITORS' REPORT
 
To the Shareholders and Directors of UnionBanCal Corporation:
 
We have audited the accompanying consolidated balance sheets of UnionBanCal
Corporation and subsidiaries (the "Company") as of December 31, 1997 and 1996,
and the related consolidated statements of income, changes in shareholders'
equity, and cash flows for each of the three years in the period ended December
31, 1997. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits. The consolidated financial statements give
retroactive effect to the merger of BanCal Tri-State Corporation and Union Bank
on April 1, 1996, which has been accounted for as a pooling of interests as
described in Note 1 to the consolidated financial statements. We did not audit
the consolidated statements of income, changes in shareholders' equity, and cash
flows of Union Bank and subsidiaries for the year ended December 31, 1995, which
statements reflect total net interest income and net income of $832 million and
$207 million, respectively. These statements were audited by other auditors
whose report has been furnished to us, and our opinion expressed herein, insofar
as it relates to the amounts included for Union Bank for 1995, is based solely
upon the report of such other auditors.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits and the report of the other auditors provide a
reasonable basis for our opinion.
 
In our opinion, based upon our audits and the report of the other auditors, the
consolidated financial statements referred to above present fairly, in all
material respects, the financial position of UnionBanCal Corporation and its
subsidiaries as of December 31, 1997 and 1996, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1997, in conformity with generally accepted accounting principles.
