                                       3
<PAGE>
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. 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 or competitive with 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
upgraded credit quality, together with a strong 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 (the "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 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 16
and 19 to the Consolidated Financial Statements included in this Form 10-K.
 
    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 above the "well capitalized" levels. At December 31, 1996,
the Company and the Bank met the requirements of a "well capitalized"
institution.
 
    Furthermore, the activities of the broker-dealer subsidiary of the Bank,
UBOC Investment, Inc., are subject to the rules and regulations promulgated by
the Securities and Exchange Commission and the National Association of
Securities Dealers, Inc., 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 acquisitions of other financial institutions.
 
    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
 
                                       4
<PAGE>
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 amongst 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, 1996, the Company operated 238 full service branches and 31
limited service offices in California, 5 full service branches in Oregon and
Washington, and 17 overseas branches and business offices. The Company owns the
property occupied by 71 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
5 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.

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, resulting in UnionBanCal Corporation and its banking subsidiary now known
as Union Bank of California, N.A.
 
    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-26 (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 that follows which presents
income before merger and integration expense and income taxes and related pro
forma ratios and per share calculations.
 
OVERVIEW
 
    Net income in 1996 was $249 million, including $72 million (after-tax) of
merger and integration related expense recorded in connection with the April 1,
1996, combination of Union Bank and BanCal Tri-State Corporation. Net income in
1995 was $313 million. Net income applicable to common stock was $225 million,
or $4.11 per common share, in 1996, compared with $284 million, or $5.21 per
common share, in 1995. Excluding after-tax merger and integration expense, pro
forma earnings for 1996 were $321 million. Pro forma earnings applicable to
common stock were $293 million, or $5.35 per common share, an increase of 3
percent over the comparable figures for 1995. Pro forma earnings were higher due
to a 2 percent increase in net interest income, a 6 percent increase in
noninterest income, and a $13 million reduction in the provision for credit
losses, partially offset by a 4 percent increase in noninterest expense
(excluding merger and integration expense) and an increase in the effective
income tax rate.
 
    The return on average assets for 1996 was 0.89 percent, compared to 1.22
percent for 1995. The pro forma return on average assets (excluding after-tax
merger and integration expense) was 1.15 percent for 1996. The return on average
common equity for 1996 was 10.3 percent, compared with 13.9 percent for 1995.
The pro forma return on average common equity (excluding after-tax merger and
integration expense) was 13.4 percent for 1996.
 
    On a taxable-equivalent basis, net interest income was $1,175 million in
1996, an increase of $23 million, or 2 percent, over 1995. Average loans
increased $1,550 million, or 8 percent, while the net interest margin declined
30 basis points to 4.75%.
 
    Noninterest income was $419 million in 1996, an increase of $23 million, or
6 percent, over 1995. Service charges on deposit accounts and trust fees were
the largest components of noninterest income, and each grew 7 percent during
1996.
 
    Excluding merger and integration expense, noninterest expense in 1996 was
$39 million, or 4 percent, higher than in 1995. Increases in salaries and
benefits and occupancy expense (due to a $12 million charge
 
                                      F-2

related to former banking facilities) were partially offset by reductions in
federal deposit insurance expense and other expense. The efficiency ratio in
1996 was 71.0 percent, compared with 63.4 percent in 1995. Excluding merger and
integration expense, the efficiency ratio was 63.6 percent in 1996.
 
    Merger and integration expense in 1996 was $117 million, including $54
million in facilities expense, $40 million in employee-related expense, $8
million in professional fees, and $16 million in other expense.
 
    The provision for credit losses was $40 million in 1996, compared with $53
million in 1995, reflecting improvement in the quality of the Company's loan
portfolio and a reduction in nonaccrual loans. Net loans charged off in 1996
were $71 million, or 0.35% of average loans outstanding, compared with $61
million, or 0.32% of average loans outstanding, in 1995.
 
    Total loans at December 31, 1996, were $20.9 billion, an increase of $672
million, or 3 percent, over year-end 1995, primarily due to growth in both the
residential and commercial mortgage portfolios.
 
    Total nonperforming assets at December 31, 1996, were $157 million, a
decline of $90 million, or 36 percent, from one year earlier. Total nonaccrual
loans were $128 million at December 31, 1996, compared with $208 million at
year-end 1995, resulting in a reduction in the ratio of nonaccrual loans to
total loans from 1.03% at December 31, 1995 to 0.61% at year-end 1996. The
allowance for credit losses was $524 million, or 408% of total nonaccrual loans,
at December 31, 1996, compared with $555 million, or 267% of total nonaccrual
loans, at December 31, 1995.
 
    At December 31, 1996, the Tier 1 risk-based capital ratio was 9.1% and the
total risk-based capital ratio was 11.2%, 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, 1996, exceeded the
regulatory guidelines for "well-capitalized" banks. The Company's leverage ratio
was 8.4% at December 31, 1996, 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. Included in interest income on loans is the amortized
     portion of net loan origination fees (costs), representing an adjustment to
     the yield.
 
(3)  Yields on investment securities available for sale are based on fair value.
     The difference between these yields and those based on amortized cost was
     not significant.

    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
interest bearing liabilities.
 
    Net interest income before the provision for credit losses on a
taxable-equivalent basis was $1,175 million in 1996, compared with $1,153
million in 1995. The increase of $23 million was primarily attributable to an
increase in average loans, partly offset by the effect of a decrease in the net
interest margin from 5.05% in 1995 to 4.75% in 1996. The decrease in net
interest margin was primarily attributable to a decrease in the proportion of
funding provided by noninterest bearing and lower cost (interest bearing and
savings and consumer time deposits) sources of funds and to an increase in the
cost of such funding sources while rates earned on assets declined. The average
proportion of funding provided by noninterest bearing and other lower cost
sources of funds decreased from 63 percent in 1995 to 61 percent in 1996,
primarily due to a higher growth rate for loans than for noninterest bearing and
other lower cost sources of funds.
 
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.

    Interest income on a taxable-equivalent basis increased $76 million in 1996,
primarily due to growth in interest income from domestic loans, which reflected
higher average balances outstanding, partially offset by a lower average yield.
 
    Interest expense increased $54 million in 1996 due to higher interest
expense on interest bearing deposits, primarily reflecting higher average
deposit balances. Interest expense on borrowed funds declined $24 million in
1996, reflecting slightly lower volumes and a 50 basis point decrease in the
average rate paid.

    Noninterest income in 1996 was $418.7 million, an increase of $23.4 million,
or 6 percent, over 1995. This included a $6.8 million increase in revenue from
service charges on deposit accounts, a $5.7 million increase in trust fees, a
$5.2 million increase in securities gains, a $4.0 million increase in bank card
fees, and a $2.5 million increase in investment services fees, partially offset
by an $8.3 million decrease in international fees and foreign exchange income.
 
    Revenue from service charges on deposit accounts was $102.0 million in 1996,
an increase of 7 percent over 1995. The increase was primarily attributable to
an increase in the volume of non-credit services provided.
 
    Trust fees were $93.5 million in 1996, 7 percent higher than in 1995,
primarily due to a larger amount of assets under management, which resulted in
higher mutual fund management fees and personal trust fees.
 
    International commissions and fees declined 4 percent to $66.1 million in
1996. The decline was primarily attributable to a reduction in the volume of
letters of credit.
 
    Credit card merchant fees were $49.8 million in 1996, an increase of 9
percent over 1995. The increase was primarily due to an increase in the volume
of credit card drafts deposited by merchants.
 
    Foreign exchange revenue declined $5.8 million, or 30 percent, in 1996,
primarily due to less volatility in the foreign exchange markets in 1996.
 
    Other noninterest income in 1996 was $8.0 million, or 21 percent, higher
than in 1995. A substantial portion of the increase consisted of items of a
nonrecurring nature.

    Noninterest expense, excluding merger and integration expense, was $1,017.4
million in 1996, an increase of $39.3 million, or 4 percent, over 1995. The
increase included a $12.0 million charge in 1996 related to former banking
facilities.
 
    Personnel-related expense was $557.2 million in 1996, an increase of $20.6
million, or 4 percent, compared with 1995. Although full-time-equivalent staff
decreased by 4 percent during 1996, the impact of the decrease was more than
offset by higher salaries and an increase of $6.6 million in outside contractor
expense (included in salaries and other compensation).
 
    Occupancy expense was $103.3 million in 1996, $10.5 million, or 11 percent,
higher than the previous year. Excluding the $12.0 million charge noted earlier,
occupancy expense in 1996 declined 2 percent due to the closure of 20 branches
late in the third quarter of 1996.
 
    Credit card processing expense was $37.1 million in 1996, an increase of
$5.8 million, or 19 percent, over 1995 due to higher merchant volumes.
 
    Advertising and public relations expense was $28.8 million in 1996, an
increase of $7.9 million, or 38 percent, over 1995. The bulk of the increase was
attributable to expanded activities in 1996 to increase awareness of Union Bank
of California, following the April 1, 1996, combination of Union Bank and BanCal
Tri-State Corporation and its banking subsidiary.

    In 1996 regulatory authority assessments expense declined to $4 million, a
decrease of $19.4 million, or 83 percent, compared with 1995. The decline was
primarily attributable to the decision of the Federal Deposit Insurance
Corporation to eliminate deposit insurance assessments for all of 1996.
 
    Foreclosed asset expense increased $6.1 million in 1996, from income of $3.2
million in 1995 to expense of $2.9 million in 1996. Gains on sales in 1996 were
insufficient to offset writedowns, operating costs, and losses.

</TABLE>
 
    The Company recorded charges totaling $40.0 million in 1996 for severance,
retention and other employee related costs stemming from the merger. During
1996, $17.6 million in payments were charged against the resulting liability
balance.
 
    Facilities costs of $53.6 million were primarily comprised of charges to
accrue the net cost of disposing of surplus bank branches and administrative
offices and properties. Noncash utilization of the facilities liability during
1996 consisted primarily of writedowns on certain administrative properties.
 
    Professional fees of $8.2 million primarily reflects the cost of legal,
accounting, and investment banking services rendered in connection with the
merger transaction. In addition, the Company incurred consulting expense in
connection with various integration activities.
 
    It is expected that additional merger-related expenses which do not qualify
for current recognition will be incurred in the first quarter of 1997. These
expenses will also be classified as merger and integration expense when incurred
and will be significantly lower in total than the $117.5 million in expense
recognized in 1996.

</TABLE>
 
    The Company's effective tax rate in 1996 was 40%, compared with 38% in 1995.
The increase in the effective rate was primarily due to a benefit recognized in
1995 from a favorable settlement of an Internal Revenue Service examination of
1989 and 1990.
 
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
 
                                      F-8
<PAGE>
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; 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 94 percent of the portfolio at December 31, 1996. Total
loans at December 31, 1996, were $20.9 billion, an increase of $672 million, or
3 percent from one year earlier. The increase was primarily attributable to the
commercial and residential mortgage portfolios, which grew by $774 million.
 
COMMERCIAL, FINANCIAL AND INDUSTRIAL LOANS
 
    Commercial, financial and industrial loans represent the largest category in
the loan portfolio. These loans are principally to major corporations, middle
market businesses, and small businesses, with no industry concentration
exceeding ten percent of total commercial, financial and industrial loans.
 
    The Company's commercial market lending is primarily originated 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, 1996, the commercial, financial and industrial loan
portfolio was $9,492 million or 45 percent of the total loan portfolio. The
decrease of $188 million, or 2 percent, from the previous year-end was primarily
attributable to planned reductions due to portfolio overlap arising from the
merger and to a reduction in certain low margin lending.
 
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, 1996, construction loans were $358 million, $12 million
lower than at the end of the previous year. Commercial mortgage loans were
$2,598 million, an increase of $455 million, or 21 percent,
 
                                      F-10
<PAGE>
from a year earlier. This increase reflected the continuing improvement in the
West Coast economy, particularly in 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.
 
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, 1996, residential loans were $2,961 million, an increase of
$319 million, or 12 percent, from a year ago as the favorable interest rate
environment and a stronger housing market continued to generate significant
opportunities for residential mortgage lenders.
 
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, 1996, consumer loans were $3,479 million, an increase of
$136 million, or 4 percent, from one year earlier. The increase was primarily
attributable to increases in direct and indirect auto loans for used vehicles,
partially offset by a decrease in home equity balances.
 
LEASE FINANCING
 
    The Company enters into direct financing and leverage leases through an
agreement with a subsidiary of BTM. In addition, the Company originates auto
leases.
 
    At December 31, 1996, lease financing outstandings were $800 million, a
decrease of $45 million from the end of 1995. In recent years, management has
not pursued expansion of the tax advantaged portion of its portfolio.
 
LOANS ORIGINATED IN FOREIGN BRANCHES
 
    The Company's foreign loans consist primarily of short-term credit
extensions to banks and other financial institutions located primarily in Asia,
and commercial and industrial loans to major Japanese, Korean, and Taiwanese
corporations.
 
    At December 31, 1996, foreign loans totaled $1,210 million, or 6 percent of
the total loan portfolio, compared with $1,203 million, or 6 percent of total
loans, at December 31, 1995.

ALLOWANCE FOR CREDIT LOSSES
 
    The allowance for credit losses is maintained at a level considered
appropriate by management and is based on an ongoing assessment of the risks
inherent in the credit and lease portfolio, including commitments to provide
financing. The allowance is increased by the provision for credit losses, which
is charged against current period operating results, and is decreased by the
amount of net loans charged off during the period. In evaluating the adequacy of
the allowance for credit losses, management incorporates such factors as
collateral value, portfolio composition and concentration, and trends in local
and national economic conditions and the related impact on the financial
strength of the Company's borrowers. While the allowance is segmented by broad
portfolio categories to analyze its adequacy, the allowance is general in nature
and is available for the portfolio in its entirety. Although management believes
that the allowance for possible credit losses is adequate, future provisions
will be subject to continuing evaluation of inherent risk in the loan portfolio.

    The following table sets forth the allocation of the allowance for credit

    At December 31, 1996, the Company's allowance for credit losses was $524
million or 2.51 percent of the total loan portfolio and 408 percent of total
nonaccrual loans. This compares with an allowance for credit losses of $555
million or 2.74 percent of the total loan portfolio and 267 percent of total
nonaccrual loans at December 31, 1995. At year-end 1996, the unallocated portion
of the allowance for credit losses was $245 million, compared with $224 million
at the end of 1995.
 
    During 1996, the Company recorded a provision for credit losses of $40
million, a decrease of $13 million from 1995. The decline in the provision for
credit losses reflected the improvement in the quality of the Company's loan
portfolio, including a 38 percent reduction in nonaccrual loans.
 
    During 1996, the Company had net loans charged off of $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
current year recoveries to loans charged off in the previous year from 26
percent in 1995 to 36 percent 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.
 
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 included in
this Form 10-K.)
 
                                      F-14
<PAGE>
    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.

<PAGE>
    At December 31, 1996, nonaccrual loans totaled $128 million, a decrease of
$80 million, or 38 percent, from year-end 1995. The decline was primarily
attributable to a $27 million reduction in nonaccrual commercial, financial and
industrial loans and a $33 million 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, due to sales of
individual assets.
 
    Nonaccrual loans as a percentage of total loans was 0.61 percent at December
31, 1996, compared with 1.03 percent one year earlier. Nonperforming assets as a
percentage of total loans, real estate ventures and foreclosed assets improved
to 0.75 percent at year-end 1996 from 1.22 percent at December 31, 1995. At
December 31, 1996, approximately 55 percent of nonaccrual loans were real estate
related; none of the individual nonaccrual loans exceeded $6 million.
 
    Total loans 90 days past due and still accruing were $24 million at December
31, 1996, compared with $26 million at December 31, 1995.
 
    At December 31, 1996, impaired loans were $114 million and the associated
impairment allowance was $21 million, compared with $173 million and $16
million, respectively, at December 31, 1995.
 
INTEREST FOREGONE
 
    Interest foregone during 1996 and 1995 for loans that were on nonaccrual
status at December 31, 1996 and 1995, was $9 million and $18 million,
respectively. The Company received interest income during 1996 and 1995 for
loans that were on nonaccrual status at December 31, 1996 and 1995, of $5
million and $10 million, respectively.
 
LIQUIDITY
 
    Liquidity refers to the Company's ability to adjust its future cash flows to
meet the needs of depositors and borrowers and to fund operations on a timely
and cost-effective basis. The Asset & Liability Management Policy approved by
the Board of Directors requires quarterly reviews of the Company's liquidity by
the Asset & Liability Management Committee ("ALCO") composed of bank executives.
The Company's liquidity draws upon the strengths 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 56 percent of average
total assets of $27.9 billion for the year ended December 31, 1996. 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, federal funds sold and securities
purchased under resale agreements, and trading account securities. The aggregate
of these assets averaged $1.9 billion during 1996. Additional liquidity may be
provided by investment securities available for sale which amounted to $2.2
billion at December 31, 1996, and by loan maturities. At December 31, 1996, $6.5
billion of loans were scheduled to mature within one year.
 
INTEREST RATE SENSITIVITY
 
    The management of interest rate risk relates to the timing and magnitude of
the repricing of assets compared to liabilities. The objective of interest rate
risk management is to generate stable net interest income and to control risks
associated with movements in interest rates.
 
    The Asset & Liability Management Policy approved by the Board of Directors
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
mix of assets and liabilities and the use of derivative instruments such as
interest rate swaps, floors and caps.
 
                                      F-16
<PAGE>
    One method of analyzing 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 the following page
presents such an analysis, which reflects certain assumptions made by ALCO as to
the rate sensitivity of deposits without contractual maturities or repricing
dates. Such deposits 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 effects of derivatives used for hedging,
such as interest rate swaps and floors, must also be taken into account in
determining the interest rate sensitivity gap.
 
    The table that follows shows that the Company's assets that were rate
sensitive within one year exceeded liabilities and shareholders' equity that
were rate sensitive within one year by $3.8 billion at December 31, 1996.
Adjusted for the effects of derivatives used for hedging, this cumulative gap
was $2.1 billion or 8.3 percent of earning assets. Generally, an asset sensitive
gap indicates that the net interest margin would increase in a rising rate
environment and decrease in a falling rate environment.
 
    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"). While this approach is also subject to a number of
assumptions, it provides a dynamic assessment of the impact, as compared to the
static nature of gap analysis. 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, defined as the potential negative change in NII,
is measured at a 97.5% confidence level and is managed within a limit
established by the ALCO as a percentage of mean NII. At December 31, 1996, the
Company was within this limit.

CAPITAL ADEQUACY AND DIVIDENDS
 
    The Company's 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 $2,495 million at December 31, 1996, an
increase of $11 million from year-end 1995. This change was primarily a result
of $249 million of net income for 1996, offset by dividends on common stock of
$219 million (including $145 million paid to The Mitsubishi Bank, Limited in the
first quarter of 1996 by BanCal Tri-State Corporation and The Bank of
California, N.A.).
 
    The Company offers a dividend reinvestment plan that allows shareholders to
reinvest dividends in the Company's common stock at five percent below the
market price. At December 31, 1996, 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, together with earnings retention and the Company's dividend
reinvestment plan, is adequate to support normal growth in operations while
meeting regulatory capital guidelines.

- ---------------
(1)  Tier 1 capital divided by quarterly average total 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 9.08 percent and 11.17 percent, respectively, at
December 31, 1996, as compared to 9.35 percent and 11.70 percent, respectively,
at December 31, 1995. The decreases in the ratios from December 31, 1995 were
primarily attributable to the $145 million dividend paid to The Mitsubishi Bank,
Limited in the first quarter of 1996. As of December 31, 1996, management
believes the capital ratios of the Company's subsidiary bank, Union Bank of
California, N.A., met all regulatory minimums of a well-capitalized bank.
 
COMPARISON OF 1995 VERSUS 1994
 
    Net income in 1995 was $313 million, compared with $125 million in 1994. The
improvement in net income in 1995 reflected higher net interest income and
noninterest income, lower loan loss provision expense, lower noninterest
expense, and a lower effective income tax rate than in 1994.
 
    Net income applicable to common stock was $284 million, or $5.21 per common
share, in 1995, compared with $104 million, or $1.95 per common share, in 1994.
 
    The return on average assets was 1.22% in 1995 versus 0.53% in 1994. The
return on average common equity was 13.9% in 1995, compared with 5.6% in 1994.
 
    Net interest income on a taxable-equivalent basis increased by $145 million,
or 14 percent, over 1994. Average loans increased $1,359 million, or 8 percent,
and the net interest margin grew 26 basis points to 5.05%.
 
    Noninterest income increased by $35 million, or 10 percent, over 1994.
Credit card merchant fees, merchant banking fees, investment services revenue,
and foreign exchange fees collectively grew 28 percent and accounted for $23
million of the growth in noninterest income.
 
    The provision for credit losses was $53 million in 1995, $20 million, or 27
percent, lower than in 1994, reflecting the improved quality of the loan
portfolio.
 
    Noninterest expense decreased by $58 million, or 6 percent, from 1994. The
reduction was primarily the result of lower foreclosed asset and regulatory
authority assessment expenses, partially offset by higher personnel-related
expense. Foreclosed asset expense declined $77 million due to lower levels of
foreclosed assets and the stabilization of market values for such assets.
Regulatory authority assessments decreased by
 
                                      F-23
<PAGE>
$20 million, or 46 percent, from 1994, primarily due to a mid-1995 reduction in
the deposit insurance premium rate charged by the FDIC. Personnel-related
expense increased $24 million, or 6 percent, in 1995, reflecting higher staff
levels and regular salary increases.
 
    Income tax expense was $73 million higher in 1995 than in 1994, reflecting
higher pre-tax income, but a lower effective income tax rate. The decrease in
the effective rate from 49 percent in 1994 to 38 percent in 1995 was primarily
attributable to an adjustment to state income taxes in 1994.
 
    Total loans at December 31, 1995 were $20.2 billion, an increase of $2.2
billion, or 12 percent, over year-end 1994. The increase was primarily
attributable to commercial, financial and industrial loans, which rose $1.1
billion, or 13 percent, residential mortgage loans, which grew 17 percent, and
commercial mortgage loans, which increased 21 percent. The growth in commercial,
financial and industrial loans was primarily attributable to the improved
economy in California and other specialized markets served by the Company, which
enabled the Company to substantially increase lending to well-qualified
borrowers. The growth in residential mortgage loans reflected the favorable
interest rate environment in 1995, which stimulated higher originations. The
growth in commercial mortgage loans was primarily due to higher originations of
mini-perm loans of $1 million to $10 million.
 
    Total nonperforming assets were $247 million at December 31, 1995, $174
million, or 41 percent, lower than one year earlier. Nonaccrual commercial
mortgage loans accounted for $81 million of the decrease, reflecting successful
workout strategies and an improvement in the California real estate sector in
1995. Nonaccrual construction loans declined $34 million, or 46 percent, in
1995, while nonaccrual commercial, financial and industrial loans fell $22
million. Net loan charge offs in 1995 were $61 million, compared to $202 million
in 1994. The $141 million, or 70 percent, decrease was principally due to a $58
million reduction in charge offs of commercial, financial and industrial loans
and a $71 million reduction in charge offs of commercial and residential
mortgage loans, while loan loss recoveries were essentially flat. The reduction
in charge offs was due to a decrease in new nonperforming assets in 1995 and a
reduction in nonaccrual and underperforming loans, reflecting improved economic
conditions and successful workout strategies.
 
    At December 31, 1995, the Tier 1 risk-based capital ratio was 9.4% and the
total risk-based capital ratio was 11.7%, compared with ratios of 9.2% and
12.0%, respectively, at December 31, 1994.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        DECEMBER 31, 1996, 1995 AND 1994
 
NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NATURE OF
        OPERATIONS
    UnionBanCal Corporation is a bank holding company owned 81 percent by The
Bank of Tokyo-Mitsubishi, Ltd. ("BTM"). It resulted from the combination on
April 1, 1996, of Union Bank with BanCal Tri-State Corporation and its banking
subsidiary, The Bank of California, N.A. UnionBanCal Corporation, its banking
subsidiary now known as Union Bank of California, N.A. ("Bank") and its other
subsidiaries are collectively referred to as "the Company". The combination was
accounted for as a reorganization of entities under common control (similar to a
pooling of interests) and, accordingly, all historical financial information has
been restated as if the combination had been in effect for all periods
presented. Additional information pertaining to the combination is presented in
Note 2.
 
    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.
 
  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.
 
  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 SECURITIES
 
    Trading account securities are designated as such when acquired based on
management's intent to use these securities for trading purposes. Trading
account positions are carried at market value. Realized gains and losses from
the close out of trading account positions and unrealized market value
adjustments are recognized in noninterest income.
 
  INVESTMENT SECURITIES AVAILABLE FOR SALE
 
    Investment securities available for sale are all securities not classified
as either held to maturity or trading account securities. Investment securities
available for sale are carried at fair value, with unrealized gains or losses
reported net of taxes as a separate component of shareholders' equity until
realized. Realized gains or losses from the sale of investment securities are
determined using the specific identification method and are included in
noninterest income.
 
  INVESTMENT SECURITIES HELD TO MATURITY
 
    Investment securities held to maturity are carried at cost, adjusted for
premium amortization or discount accretion computed using the effective interest
method. The Company has the intent and ability to hold these securities to their
maturities. Realized gains or losses on sales, if any, are included in
noninterest income.

                        DECEMBER 31, 1996, 1995 AND 1994
 
NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NATURE OF
        OPERATIONS (CONTINUED)
  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
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. Except for
small business loans that are processed centrally and consumer loans, which are
charged off within 180 days of becoming past due, interest accruals are
continued for loans that have become contractually past due 90 days only when
such loans 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 accrued but
uncollected interest. Interest income is recognized 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.
 
    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 and unamortized investment
tax credits.
 
  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 losses inherent in
the existing portfolio, including commitments under commercial and standby
letters of credit and guarantees. The allowance for credit losses is increased
by the

NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NATURE OF
        OPERATIONS (CONTINUED)
provision for credit losses, which is charged against current period operating
results and decreased by the amount of net loan charge-offs during the period.
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.
 
    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 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, management attributes portions of the allowance for credit losses to
individual loans or groups of loans. However, the allowance for credit losses is
available to absorb all credit losses that arise from the loan and lease
portfolio and is not segregated for, or allocated to, any particular loan or
group of loans. 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. Impaired loans are carried at
the estimated present value of total expected future cash flows, discounted at
the loan's effective rate, or at the fair value of the collateral if less than
the recorded investment in the loan (including accrued interest, net deferred
loan fees or costs and unamortized premium or discount). An impairment is
recognized by adjusting an allocation of the existing allowance for credit
losses.
 
  OTHER REAL ESTATE OWNED ("OREO")
 
    At the time collateral from a loan is foreclosed upon, the collateral is
transferred from loans to OREO at the lesser 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 book values are reviewed
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 as noninterest expense. The book value of OREO assets is included
in Other Assets in the Consolidated Financial Statements.
 
  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 the estimated useful life of ten years, whichever is
shorter.
 
  GOODWILL AND OTHER ASSETS
 
    The excess of purchase price over the fair value of net assets of acquired
companies is classified as goodwill and reported as intangible assets. Goodwill
is amortized using the straight-line method, generally over 15 years.

NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NATURE OF
        OPERATIONS (CONTINUED)
  DERIVATIVE INSTRUMENTS HELD FOR TRADING OR CUSTOMER ACCOMMODATION
 
    The Company is party to a variety of derivative transactions, including
foreign exchange forward contracts, currency and interest rate swap contracts,
and interest rate cap and floor agreements. These contracts are entered into for
trading purposes or as a service to customers. Derivatives held for trading or
customer accommodation are designated as such when acquired based on
management's intent.
 
    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 other assets and
other liabilities. Cash flows are reported net as operating activities.
 
 DERIVATIVE INSTRUMENTS HELD FOR PURPOSES OTHER THAN TRADING
 
    The Company is party to a variety of derivative transactions, including
foreign exchange forward contracts, currency and interest rate swap contracts,
and interest rate cap and floor agreements. These contracts are entered into as
a means of reducing the Company's interest rate or foreign exchange risk and are
designated as such when acquired based on management's intent. The Company
monitors the results of each transaction to insure that management's intent is
satisfied. The Company does not use derivatives to hedge anticipated
transactions.
 
    Gains and losses on foreign exchange forward contracts and on the related
asset and liability are deferred and amortized over the life of the hedged
transaction as interest income or interest expense.
 
    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. Unamortized premiums paid are
included in other assets. Unamortized premiums received are included in other
liabilities. Net settlement amounts are reported gross as other assets and other
liabilities. Cash flows are reported net as operating activities.
 
  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
 
    Primary and fully diluted earnings per share are computed based on net
income after preferred dividends and parent direct interest and are based on the
weighted average number of common shares and equivalent common shares
outstanding during the period. Both stock options and restricted stock (see Note
13) are common stock equivalents. For the years presented, stock options and
restricted stock did not have a dilutive effect and are not included in the
Company's earnings per share calculation.

NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NATURE OF
        OPERATIONS (CONTINUED)
  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 Statement of Financial
Accounting Standards ("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 Restricted Stock Program is
measured based on the market price of the stock at the grant date and is
expensed over the vesting period.
 
  NEW ACCOUNTING PRONOUNCEMENTS
 
    On January 1, 1996, the Company adopted SFAS No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of,"
which addresses the accounting for the impairment of long-lived assets, such as
premises, furniture and equipment, certain identifiable intangibles and goodwill
related to those assets. Long-lived assets and certain identifiable intangibles
are to be reviewed for impairment whenever events or changes in circumstances
indicate that the carrying amount of an asset may not be recoverable. An
impairment loss is recognized when the sum of the future cash flows expected
from the use of the asset and its eventual disposition (undiscounted and without
interest charges) is less than the carrying amount of the asset. The Statement
also requires that long-lived assets and identifiable intangibles, except for
assets of a discontinued operation held for disposal, be accounted for at the
lower of cost or fair value less cost to sell. The Company has implemented SFAS
No. 121 and, except for the effects of the writedown of certain assets and
leases in connection with the recognition of merger and integration costs, has
determined that the measurement of impairment loss is not material.
 
    In June 1996, SFAS No. 125, "Accounting for Transfers and Servicing of
Financial Assets and Extinguishments of Liabilities" was issued. 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 after December 31, 1996. In December 1996, the
Financial Accounting Standards Board ("FASB") reconsidered certain provisions of
SFAS No. 125 and issued SFAS No. 127, "Deferral of the Effective Date of Certain
Provisions of FASB Statement No. 125" to defer for one year the effective date
of implementation for transactions related to repurchase agreements, dollar-roll
repurchase agreements, securities lending and similar transactions. Earlier
adoption or retroactive application of this statement with respect to any of its
provisions is not permitted. Management believes that the effect of adoption on
the Company's financial statements will not be material.

NOTE 2 -- MERGER; COMBINATION OF UNION BANK AND SUBSIDIARIES AND BANCAL TRI-
         STATE CORPORATION AND SUBSIDIARIES
    As discussed in Note 1, the combination of Union Bank and BanCal Tri-State
Corporation in a merger to form UnionBanCal Corporation and subsidiaries was
completed on April 1, 1996, and was accounted for as a reorganization of
entities under common control (similar to a pooling of interests). The merger
was effected by the issuance of 18,134,027 shares of Union Bank common stock in
exchange for all the outstanding common shares of BanCal Tri-State Corporation.
All historical information has been restated as if the merger had been in effect
for all periods presented.
 
    The following table presents certain financial data pertaining to the
combination of Union Bank with BanCal Tri-State Corporation for periods prior to
April 1, 1996. Certain reclassifications and restatements of historical data
have been made to conform to consistent methods of accounting. The principal
restatements include the results of conforming the date of adoption of SFAS No.
115, "Accounting for Certain Investments in Debt and Equity Securities" to
December 31, 1993, and the results of restating 1994 and 1993 to reflect
adoption of SFAS 109, "Accounting for Income Taxes", effective January 1, 1993,
with the recognition of certain deferred tax assets at that date as a cumulative
effect of a change in accounting principle. The restatement for income taxes
resulted in an increase in 1993 net income of $172 million which reflected the
net effect of the accounting change and in 1994 a corresponding $172 million
decrease in net income which reflected the increase in income tax expense of
$172 million.

(1)  These loans do not require an impairment allowance since the value of the
     impaired loan collateral equals or exceeds the recorded loan balance.
 
(2)  This amount was evaluated for impairment using two measurement methods as
     follows: $52 million and $72 million was evaluated using the present value
     of the expected future cash flows at December 31, 1996 and 1995,
     respectively; and $62 million and $101 million was evaluated using the fair
     value of the collateral at December 31, 1996 and 1995, respectively.
 
  RELATED PARTY LOANS
 
    The Company in some cases makes related party loans to its directors,
executive officers and their affiliated companies. At December 31, 1996, related
party loans outstanding to individuals who served as directors or executive
officers at anytime during the year totaled $79 million as compared to $34
million at December 31, 1995. 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 1996 and 1995, there were no loans to related parties which were
charged off. Additionally, at December 31, 1996 and 1995, there were no loans to
related parties which were nonperforming.

  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. It is anticipated that
the plan covering former BanCal Tri-State Corporation employees will be
terminated, retroactive to January 1, 1997, and those employees will be covered
by the remaining plan.
 
    The former Union Bank Retirement Plan (the "Plan") is a qualified retirement
plan covering substantially all of the employees of the former Union Bank. The
Plan is a noncontributory defined benefit plan which provides benefits upon
retirement based on years of service and average compensation, as defined in the
Plan. Annual contributions are based on an amount which satisfies federal
funding standards. 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 trust funds.
 
    The following sets forth the Plan's funded status and the amounts recognized
in the Company's balance sheets at the dates indicated.

    The former BanCal Tri-State Corporation retirement plan is a defined
contribution plan. Company contributions are based upon employees' eligible
compensation. Depending upon employee entitlements, the Company contributions
range from 5 to 10 percent of an employee's eligible compensation. The Company's
expense for pension contributions for the years ended December 31, 1996, 1995,
and 1994 was $5 million, $6 million and $6 million, respectively.
 
  EXECUTIVE SUPPLEMENTAL BENEFIT PLANS
 
    The Company has Executive Supplemental Benefit Plans ("ESBP") which provide
eligible employees with monthly benefits upon retirement. The plans are
unfunded. The accrued liability for ESBP's included in other liabilities in the
consolidated balance sheets was $14 million and $14 million at December 31, 1996
and 1995, respectively. The Company's expense relating to the ESBPs was $1
million for each of the years ended December 31, 1996, 1995 and 1994.
 
  SECTION 401 SAVINGS PLANS
 
    The Company has two qualified savings plans (one for former Union Bank
employees and one for former BanCal Tri-State employees) authorized under
Section 401 of the Internal Revenue Code. The Company's combined matching
contribution expense was $9 million in each of the years ended December 31,
1996, 1995 and 1994.
 
  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 unrecognized transition obligation recorded on January 1, 1993, is being
amortized over 20 years.
 
    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 health maintenance
organization ("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 increase on the HMO plan increased to 7
percent in 1997 and then gradually decreased 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, 1996, by $9 million and the
aggregate of the service and interest cost components of net periodic
postretirement benefit cost of the year then ended by $1 million.
 
    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.
 
    For 1994, former Union Bank assumed a 9 percent annual rate of increase in
the per capita cost of postretirement medical benefits for the indemnity plan.
No increase was assumed for the HMO plan. The annual rate of increase for both
plans were assumed to decrease gradually to 5.5 percent by 2008 and remain level
thereafter. For the former BanCal Tri-State Corporation, the assumed rate of
future increases in the health care cost trend rate was 12.25 percent for 1994,
gradually decreasing to 6.5 percent for the year 2003 and remaining level
thereafter.
 
    The discount rate used in determining the actuarial present value of the
projected benefit obligation was 7.50 percent as of December 31, 1996 and 1995.
At December 31, 1994, the discount rate was 9.00 percent for BanCal Tri-State
and 8.25 percent for Union Bank. The estimated rate of return on plan assets was
8.00 percent, 8.00 percent, and 8.25 percent as of December 31, 1996, 1995, and
1994, respectively.

    The Company has a tax indemnification agreement with Standard Chartered PLC
in connection with its acquisition of the former Union Bank in 1988. Certain
amounts have been paid to federal and state taxing authorities in settlement of
tax issues in years covered by the agreement and, accordingly, receivables from
Standard Chartered PLC have been recorded. Management believes that all such
receivables are fully collectible.
 
    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 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, 1996 and 1995, $219
million and $274 million, respectively, of the notes qualified as capital for
the total risk-based capital ratio.
 
    Provisions of several of the notes restrict the use of the Company's
property as security for borrowings, and place limitations on leases,
indebtedness, distributions to shareholders, mergers, sale of certain assets,
transactions with affiliates and changes in majority stock ownership of the
Company.

quarterly at a rate of 8 3/8 percent per annum (see Note 16 for an additional
discussion of dividends). On and after September 3, 1997, the Preferred Stock is
redeemable at the option of the Company, at a redemption price of $100 per share
of Preferred Stock (equivalent to $25 per depositary share), plus accrued and
unpaid dividends thereon from the immediately preceding dividend payment date to
the date fixed for redemption.
 
NOTE 12 -- 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. As a result of this plan, during 1996, 1995
and 1994, 23,902 shares, 620,678 shares and 617,997 shares, respectively, were
distributed under this plan. During 1994, BTM participated in the plan and
reinvested all of its dividends. BTM discontinued its participation after the
quarter ended March 31, 1995, and did not participate in the plan as of December
31, 1996.
 
NOTE 13 -- MANAGEMENT STOCK PLAN
    The Company has a management stock plan (the "Plan") which has 1,200,000
shares of the Company's common stock authorized to be awarded to key employees
of the Company and its subsidiaries at the discretion of the Executive
Compensation and Benefits Committee of the Board of Directors (the "Committee").
Pursuant to the Plan, the Committee established the Restricted Stock Program and
the Stock Option Program. Committee members, members of the Board who are not
full-time employees, and employees on rotational assignment from BTM are not
eligible for stock awards. The combined number of shares that are granted under
the Restricted Stock Program and the Stock Option Program cannot exceed
1,200,000 shares of the Company's common stock.
 
    The Committee determines the term of each stock option up to a maximum of
ten years from the date of grant. The exercise price of the options issued under
the Stock Option Program shall not be less than the fair market value on the
date the option is granted. Unvested restricted stock issued under the
Restricted Stock Program is shown as a reduction to retained earnings. The value
of the restricted shares at 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 1996, 1995 and 1994, the Company granted options to various key
employees, including principal officers, under the Stock Option Program. 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 or retires under certain grant, age, and service conditions.

    At December 31, 1996 and 1995, 319,461 shares and 447,483 shares,
respectively, were available for future grants as either stock options or
restricted stock under the Plan.
 
    The Company follows the intrinsic value based method in accounting for its
employee stock-based compensation plans. Accordingly, no compensation cost has
been recognized for its stock option plans. Had compensation cost for the
Company's stock-based plans been determined based on the fair value at the grant
dates for awards under those plans 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. As 1996 is the initial phase-in period for applying this
Statement, the pro forma results indicated are not necessarily representative of
the effects on pro forma disclosures of net income for future periods as they
exclude options that were granted prior to January 1, 1995, with vesting periods
in 1995 and later.

    The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option pricing model with the following weighted-average
assumptions used for grants made in 1996 and 1995: risk-free interest rates of
6.3% in 1996 and 7.1% in 1995; expected volatility of 28% in 1996 and 28% in
1995; expected lives of 7 years for both years and expected dividend yields of
2.6% in 1996 and 4.2% in 1995.

NOTE 14 -- 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, 1996 and 1995, 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 table below presents the carrying value and fair value of the specified
assets and liabilities held by the Company.

    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 15.
 
    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.
 
    INVESTMENTS AND TRADING ACCOUNT SECURITIES:  Fair values of investments and
trading account securities are 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.

NOTE 14 -- FAIR VALUE OF FINANCIAL INSTRUMENTS (CONTINUED)
    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.
 
    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 determined
assuming these loans were sold on a liquidation basis based on the Company's
understanding of similar nonrecourse sales transactions which have been entered
into by financial institutions during 1996 and 1995.
 
    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, 1996 and 1995, by
segregating them according to their past due status and then discounting them
based on the Company's historical probability of loss.
 
    DEMAND DEPOSITS:  The fair value of demand deposits is the amount payable on
demand at the reporting date. The fair value of the demand deposit intangible
has not been estimated.
 
    OTHER 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 15 -- 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
 
                                      F-52

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.
 
  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, 1996, 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, 1996 and 1995,
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 material. 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, 1996 and 1995.

NOTE 15 -- 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, 1996 and 1995, fair value is
comprised of unamortized fee income less any allocated reserves for expected
credit losses. The following is a summary of other financial instruments with
off-balance sheet risk.

NOTE 15 -- DERIVATIVE INSTRUMENTS AND OTHER FINANCIAL INSTRUMENTS WITH
          OFF-BALANCE SHEET RISK (CONTINUED)
    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 $1,170
million and $1,101 million at December 31, 1996 and 1995, respectively. The
market value of the associated collateral was $1,195 million and $1,122 million
at December 31, 1996 and 1995, respectively.
 
NOTE 16 -- 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 $291 million and $335 million for the years ended
December 31, 1996 and 1995, respectively.
 
    As of December 31, 1996 and 1995, securities carried at $1.7 billion and
$1.8 billion, respectively, and loans of $1.8 billion and $1.1 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, 1996, such extensions of credit were not material.
 
    The payment of dividends by the Bank to UnionBanCal Corporation and BTM 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, 1996 the Bank
could have declared dividends aggregating $174 million without prior regulatory
approval. Dividends on the Company's common stock are further restricted by
certain provisions of the Company's outstanding noncumulative preferred stock.
These provisions specify that no common stock dividend shall be declared, paid
or set aside unless and until the Company has paid full dividends on the
preferred stock for the four most recent quarterly dividend periods.
 
NOTE 17 -- REGULATORY CAPITAL REQUIREMENTS
    The Company and the Bank are subject to various regulations issued by
Federal banking agencies, including minimum capital requirements. Failure to
meet minimum capital requirements can initiate certain actions by regulators
that, if undertaken, could have a material effect on the Company's consolidated
financial statements. Under capital adequacy guidelines, the Company and the
Bank must meet specific capital guidelines that involve quantitative measures of
the 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,
1996, that the Company and the Bank meet all capital adequacy requirements to
which they are subject.
 
    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

                              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, 1996,
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, which was 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-64.

                          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, 1996 and 1995,
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, 1996. 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 2 to the consolidated financial statements. We did not audit
the consolidated financial statements of Union Bank and subsidiaries, which
statements reflect total assets, total net interest income, and net income of
$19,518 million, $832 million and $207 million, respectively, in 1995 and $713
million and $63 million of net interest income and net income, respectively, in
1994 of the related consolidated totals. 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
and 1994, 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, 1996 and 1995, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1996, in conformity with generally accepted accounting principles.

                               UNION BANK OF CALIFORNIA
                              DEFERRED COMPENSATION PLAN


                                      ARTICLE I
                                 HISTORY AND PURPOSE

1.1  Union Bank established the Senior Management Deferred Compensation Plan
     effective July 1, 1990 for the purpose of allowing a select group of
     executives of Union Bank to defer receipt of compensation to which the
     executives would otherwise be entitled.  The Plan was amended and restated
     in its entirety as of January 1, 1994.  As a consequence of the merger of
     their respective parent companies, Union Bank and the Bank of California
     have been merged into a new operating entity, Union Bank of California.

1.2  Union Bank of California hereby amends and restates the Plan in its
     entirety effective January 1, 1997, to reflect the merger of Union Bank
     and the Bank of California and to extend participation to the non-employee
     directors of Union Bank of California and the non-employee directors of
     UnionBanCal Corporation  and to rename the Plan, the Union Bank of
     California Deferred Compensation Plan.


                                      ARTICLE II
                                     DEFINITIONS

     designation, the Participant's surviving spouse shall be the Beneficiary

     the Senior Management Bonus Plan or those incentive awards designated by
     the Bank as Compensation under this Plan which, but for deferral under
     this Plan, would have been paid to the Participant in cash.
     "Compensation" shall be calculated without regard to any salary reduction

     Participant participates and which is maintained by the Bank.

2.8  "Deferral Election Form" means the agreement between a Participant and the

     subsidiaries or a non-employee Director of UnionBanCal Corporation.  A
     Director who becomes an Employee shall cease to participate as a Director

     subject to the provisions of the Plan (including eligibility).

2.10 "Disabled" describes a Participant who while an Employee becomes
     permanently and totally prevented from engaging in substantial gainful

     Election Form or (b) who has previously deferred Compensation or Fees
     under the Plan and who continues to have an Account balance greater than
     zero.

2.15 "Payment Date" means the date on which a Participant's Account is to be

     or involuntary termination of employment with the Bank.  With respect to
     Directors, "Termination of Service" means the Director has voluntarily or
     involuntarily ceased to serve as a member of the Board.


                                     ARTICLE III
                                     ELIGIBILITY

The Board (or if designated, the Committee) shall determine which Employees and
Directors are eligible to participate in the Plan, provided that only those
Employees who are members of a select group of management or highly compensated
employees (within the meaning of ERISA Sections 201, 301 and 401) shall be
eligible Employees.


                                      ARTICLE IV
                                  ELECTION TO DEFER

4.1  An Employee may elect to defer receipt of Compensation by completing the
     Deferral Election Form prescribed by the Committee and specifying the
     percentage (in 5 percent increments up to a maximum of 50% of base salary
     and a maximum of 100% of bonuses and other incentive awards)) of
     Compensation to be deferred. A Director may elect to defer receipt of Fees
     by completing the Deferral Election Form prescribed by the Committee and
     specifying the percentage (in 5% increments up to a maximum of 100%) of
     Retainer Fees and/or Meeting Fees to be deferred.  To be effective, a
     Deferral Election Form must be signed and dated by the Participant, and
     signed and dated by the Human Resources Department.

4.2  The Deferral Election Form must be received by the Human Resources
     Department before the beginning of the period for which the Compensation
     or Fees are earned.  Therefore, the deadline for electing to defer the
     annual Senior Management Bonus is December 31 of the year preceding the
     year for which the Bonus is earned.  The deadline for electing to defer
     base salary is thirty (30) days prior to the beginning of the first
     payroll period in which the deferral is effective.  The deadline for a
     Director's election to defer Retainer Fees and/or Meeting Fees is December
     31 of the year preceding the Plan Year in which the meetings occur and the
     service is rendered.

4.3  An election to defer Fees or Compensation attributable to bonuses,
     incentive awards or base salary already earned shall be irrevocable.  An
     election to defer Compensation attributable to base salary may be revoked
     with respect to base salary not yet earned, but may not be amended to
     otherwise increase or decrease the elected percentage.  The revocation
     must be in writing and received by the Human Resources Department no less
     than thirty (30) days prior to the beginning of the payroll period in
     which the revocation is effective.  If a Participant revokes an election
     to defer Compensation, he or she is precluded from again deferring base
     salary until the next Plan Year.


                                          3

<PAGE>

4.4  Each Deferral Election Form shall specify the Payment Date which shall be
     either:

     (a)  the Participant's Termination of Service, or

     (b)  January 31 of any year subsequent to the year in which the
          Compensation or Fees would have been paid absent the Deferral
          Election, provided that the deferral period must be at least
          12 months.

     The election of a Payment Date shall be irrevocable.

4.5  Each Deferral Election Form shall specify that the Account is to be paid:

     (a)  in a single lump sum on the Payment Date (or as soon thereafter as
          administratively feasible) or

     (b)  in four substantially equal annual installments, commencing on the
          Payment Date (or as soon thereafter as administratively feasible) or

     (c)  in ten substantially equal annual installments, commencing on the
          Payment Date (or as soon thereafter as administratively feasible).

     The election of a payment form shall be irrevocable.  Notwithstanding the
     foregoing, all Participants shall have a one-time limited opportunity to
     elect the installment option described in paragraph (c) with respect to
     Account(s) which are not currently in pay status.  The election must be
     made during the period beginning December 2, 1996 and ending with the
     close of business December 31, 1996.  Elections made during this window
     become effective with respect to Payment Dates after December 31, 1997 and
     are irrevocable.  This window election opportunity is provided because of
     a change in federal law restricting states' ability to tax pension income
     based on its source.


                                      ARTICLE V
                                       ACCOUNTS

5.1  In lieu of paying Compensation or Fees deferred pursuant to a Deferral
     Election Form, the Bank shall credit the deferred amount as of the last
     day of the month in which the Compensation or Fees would have otherwise
     been paid to an account in the name of the Participant (the "Deferred
     Compensation Account") established for this purpose on the Bank's books
     and records.  If the Participant has entered into more than one Deferral
     Election Form and they specify different Payment Dates or different
     payment forms (under Section 4.5), the Bank shall establish a separate
     Account for amounts credited pursuant to each such Deferral Election Form.

5.2  The balance credited to each Deferred Compensation Account shall be
     credited with interest at the end of each calendar quarter.  Effective for
     calendar quarters beginning on or after January 1, 1993, the interest rate
     credited shall be the 1-Year Treasury Constant Maturities Rate


                                          4

     for deferrals of less than 36 months, and the 5-Year Treasury Constant
     Maturities Rate for deferrals of 36 months or more or to the date of
     Termination of Employment.  The monthly average Treasury Constant
     Maturities Rates are quoted in the Federal Reserve Statistical Release,
     H.15, and calculated quarterly, based on a rolling average for the
     previous 12 months.  The interest applied to Compensation or Fees credited
     during a Plan Year shall be prorated for the number of months in the Plan
     Year that the Compensation or Fees were credited to the Participant's
     Account.

5.3  If, pursuant to Article VI, interest is required to be credited through
     the last day of any month (other than the end of a calendar quarter), the
     rate shall be that rate in effect under Section 5.2 as of the last day of
     the preceding quarter, prorated on a monthly basis to the crediting date.

5.4  If, pursuant to the provisions of Article VI, a Participant is paid
     deferred amounts in the same Plan Year in which the amounts would
     otherwise have been paid as Compensation or Fees, those amounts will be
     credited with interest as described in Section 5.3 through the date
     specified in Article VI.


                                      ARTICLE VI
                                 PAYMENT OF ACCOUNTS

6.1  GENERAL RULE.  Amounts credited to a Participant's Account(s) shall be
     paid as specified in the Deferral Election Form on or commencing on the
     Payment Date or as soon thereafter as administratively practicable.  The
     unpaid balance of a Participant's Account(s) being paid in installments
     shall continue to be credited with the interest specified in Article V
     through the last day of the month preceding the last installment payment.
     Accounts which are to be paid in a single lump sum shall be credited with
     the interest specified in Article V through the last day of the month
     preceding the Payment Date.  All payments shall be in cash.

6.2  EMPLOYEE'S VOLUNTARY TERMINATION.  Notwithstanding the provisions of
     Section 6.1, if an Employee's Termination of Service precedes his
     designated Payment Date for any Account(s) and the Termination of Service
     is voluntary (other than a Retirement),

     (a)  all amounts credited to his Accounts shall be paid to the Participant
          in a single lump sum (without regard to the Participant's designated
          Payment Date or payment form) as soon as administratively practicable
          with interest credited under Article V through the end of the
          calendar quarter preceding the Termination of Service,

     (b)  any Accounts being paid in installments shall be accelerated with the
          remaining installments paid in a single lump sum with interest
          credited under Article V through the last day of the preceding
          quarter.

     For purposes of this Article, an Employee's Termination of Service is
     treated as a "Retirement" if the Participant is eligible to commence
     benefits under the Union Bank of California Retirement Plan on the
     termination date.


                                          5

<PAGE>

6.3  INVOLUNTARY TERMINATION.  Notwithstanding the provisions of Section 6.1,
     if an Employee's Termination of Service is due to involuntary termination
     by the Bank (and the termination is not a Retirement),

     (a)  any Accounts currently being paid in installments will continue to be
          so paid with interest credited as provided in Section 6.1,

     (b)  all other Accounts shall be paid to the Participant in a single lump
          sum (without regard to the Participant's designated Payment Date or
          payment form) as soon as administratively practicable with interest
          credited as provided in Section 6.1.

6.4  DEATH.  Notwithstanding Section 6.1, if a Participant dies before
     receiving his entire Account(s), the balance shall be paid to his
     Beneficiary in four substantially equal annual installments commencing on
     January 31 of the year following the year death occurs, unless the
     Committee in its discretion decides to accelerate payment in a single lump
     sum. The Account shall continue to be credited with the interest specified
     in Article V through the last day of the month preceding the last
     installment payment (or the lump sum payment if payment is accelerated) to
     the Beneficiary.  Notwithstanding the foregoing, if the Participant was
     receiving installment payments under the Plan, remaining installments
     shall be paid to the Beneficiary as though he were the Participant unless
     the Committee in its discretion decides to accelerate the installments and
     pay the Beneficiary in a single lump sum.

6.5  DISABILITY AND HARDSHIP.  Prior to the Payment Date, payment of amounts
     credited to a Participant's Account(s) may be permitted only if the
     Committee determines that the Participant is Disabled or has a financial
     hardship.  "Hardship" requires an immediate and heavy financial need of
     the Participant which was not reasonably foreseeable and which cannot be
     satisfied from other resources reasonably available to the Participant.
     The amount of any hardship payment shall not exceed the amount required to
     meet the need.  The Participant shall submit a written request to the
     Committee and shall certify as to the financial need.  The Committee shall
     have sole discretion to determine whether to make a hardship payment and
     to determine the amount of such payment, if any.  The Committee may
     accelerate installment payments in the event of a Participant becomes
     Disabled or incurs a hardship.  The Committee's decision as to the
     Participant's Disabled status or hardship shall be final and binding on
     all interested parties.


                                     ARTICLE VII
                                 PLAN ADMINISTRATION

7.1  This Plan shall be adopted by the Board of Union Bank of California and
     shall be administered by the Committee.

7.2  This Plan may be amended in any way or may be terminated, in whole or in
     part, at any time, at the discretion of the Board of Union Bank of
     California.  No amendment or termination of the Plan shall adversely
     affect the amount in any Participant's Account prior to or as of the
     effective date of such amendment or termination.


                                          6

<PAGE>

7.3  The Committee shall have the sole authority, in its discretion, to adopt,
     amend and rescind such rules and regulations as it deems advisable in the
     administration of the Plan, to construe and interpret the Plan, the rules
     and regulations, and Deferral Election Forms, and to make all other
     determinations and interpretations of the Plan.  All decisions,
     determinations, and interpretations of the Committee shall be binding on
     all persons.  Committee members who are Participants shall abstain from
     voting on any Plan matters that would cause them to be in constructive
     receipt of amounts credited to their Accounts.  The Committee may delegate
     its responsibilities as it sees fit.


                                     ARTICLE VIII
                                    MISCELLANEOUS

8.1  NO FUNDING OBLIGATION.  The amounts credited to a Participant's Account
     are not held in a trust or escrow account and are not secured by any
     specific assets of the Bank or in which the Bank has an interest.  This
     Plan shall not be construed to require the Bank to fund any of the
     benefits provided hereunder nor to establish a trust for such purpose.
     The Bank may make such arrangements as it desires to provide for the
     payment of benefits.  Neither the Participant, any Beneficiary nor the
     Participant's estate shall have any rights against the Bank with respect
     to any portion of the Participant's Account except as a general unsecured
     creditor of the Bank.  No Participant has an interest in his Accounts
     until the Participant actually receives payment.

8.2  NON-ALIENATION OF BENEFITS.  No benefit under this Plan may be sold,
     assigned, transferred, conveyed, hypothecated, encumbered, anticipated, or
     otherwise disposed of, and any attempt to do so shall be void.  No such
     benefit shall, prior to receipt thereof by a Participant, be in any manner
     subject to the debts, contracts, liabilities, engagements, or torts of
     such Participant.

8.3  LIMITATION OF RIGHTS.  Nothing in this Plan shall be construed to limit in
     any way the right of the Bank to terminate an Employee's employment at any
     time for any reason whatsoever with or without cause; nor shall it be
     evidence of any agreement or understanding, express or implied, that the
     Bank (a) will employ an Employee in any particular position, (b) will
     ensure participation in any incentive programs, or -C- will grant any
     awards from such programs.

8.4  APPLICABLE LAW.  This Plan shall be construed and its provisions enforced
     and administered in accordance with the laws of the State of California
     except as otherwise provided in ERISA.

     The objective of the Senior Management Bonus Plan (the Plan) is to reward
     Senior Managers who assist in achieving and exceeding the Bank's and their

     -    Executive Vice Presidents (EVP)
     -    Senior Vice Presidents (SVP) whose performance is associated

                                      BONUS PLAN

IV   BASIS FOR PAYMENT

     A.   BANK FINANCIAL GOALS

          The Bank's Plan goals are Return On Average Assets (ROA) Ratio and
          Net Income, which will be designated by the President and CEO in the
          financial planning process.   ROA is defined as:

          --------------------------------------------------------------
          --------------------------------------------------------------

                   Return On                     Net Income
                 Average Assets      =           ----------
                                            Average Annual Assets

          --------------------------------------------------------------
          --------------------------------------------------------------


     B.   INCENTIVE TARGETS

          Incentive targets with Bank performance at 100% of financial goals
          are 25% for SVPs and 35% for EVPs and above.

          Group Heads may recommend individual incentive targets that vary by
          position within officer level, taking into consideration competitive
          market factors and the criticality of the position.  Variances in
          individual incentive targets and resulting payments are subject to
          review by the COO or CFO, as appropriate, and final approval of the
          President and CEO, provided that the payments do not exceed the
          approved bonus fund designated for the respective officer level for
          each Group.

                                  SENIOR MANAGEMENT
                                      BONUS PLAN


         The President and CEO will submit bonus fund recommendations to the
         Committee, which may establish, reduce, increase, or otherwise make
         adjustments to a calculated bonus fund, subject to the maximum for
         that fund (50% for SVP fund and 70% for EVP fund) and based on the
         following:

         -    The Bank's overall performance in relation to other peer banks
         -    Whether absolute Return On Average Assets and/or Net Income goals
              are reasonable in relation to long-term objectives and the Bank's
              historical performance.
         -    Merger integration efforts and success, with particular emphasis
              on full and timely achievement of the cost reduction commitments
              that have been made to shareholders, the Board, and the investor
              community.
         -    Efficiency ratios as compared to peer banks, with recognition
              that constant attention must be given to long-term expense
              reduction through continuous productivity improvement in order to
              support UBOC's competitiveness.
         -    General economic or market conditions
         -    Achievement of other financial and strategic objectives
         -    Normalizing financial data to allow for an acquisition/merger,
              other extraordinary circumstances or material events that were
              not specifically planned or not directly related to the
              performance of Bank executives during the performance year.

    D.   DETERMINING INDIVIDUAL AWARDS

         1.   Individual bonus awards will be determined in the following
              manner:

              a.   The President and CEO will recommend awards for eligible
                   Vice Chairmen and policy-making officers to the Committee,
                   which will  then review and approve these awards, with or
                   without modification.  The recommendations of the President
                   and CEO, prior to their submittal, will have been developed
                   in conjunction with the CFO, COO, and, when relevant, the
                   Group Head to whom the policy-making officer reports.

              b.   The President and CEO, in consultation with the COO and CFO,
                   will allocate the remaining funds for non policy-making
                   officers to Group Heads based on aggregate individual
                   incentive award targets and Group performance. Any
                   adjustments to allocations, based on Group performance, must
                   be made within the approved bonus funding limits.  The
                   President and CEO will also issue guidelines for Group Heads
                   to develop individual bonus award recommendations.

                                  SENIOR MANAGEMENT
                                      BONUS PLAN


              c.   Group Heads will prepare individual EVP and eligible SVP
                   bonus award recommendations.  Recommendations by Group Heads
                   who report to the COO will then be reviewed by the COO and
                   forwarded to the CEO for final approval.  Group Heads who
                   report to the CEO will submit recommendations directly to
                   the CEO for final approval.

              d.   The Committee may request a report on bonuses awarded to
                   executives other than policy-making officers.

         2.   Individual awards may exceed the incentive target, up to a
              maximum of 50% or 70% for SVP's and EVP's, respectively, subject
              to overall bonus funding limits.  Individual awards above the
              maximum may be granted in exceptional circumstances and require
              the approval of the President and CEO and the Committee.

         3.   Vacation, sick pay, retirement, and all other employee benefit
              plans excluding the 401(k) plan are based on the base salary rate
              and do not include Senior Management Bonus payments.


V.  ADMINISTRATION

    A.   The final authority and responsibility for administration of the Plan
         resides exclusively with the Committee.

    B.   The Director of Finance will have responsibility for calculating the
         bonus funds including the application of any fund limitations
         specified by the Committee.  The bonus funds will be rounded to the
         nearest thousand dollars and individual awards will be rounded to the
         nearest one hundred dollars.

    C.   The Director of Human Resources will have responsibility for providing
         the Director of Finance with information on Bonus-eligible executives
         and salaries, processing award payments, and keeping records of
         activities related to the Plan.

    D.   The award payments will be made as soon as administratively practical
         after the end of the fiscal year.

    E.   New participants will be eligible to receive a pro-rated award based
         on the number of months worked (rounded-up) as a participant during
         the Plan year.

                                      BONUS PLAN


    F.   Participants on Leave of Absence during part of the Plan year will be
         eligible for a pro-rated award payment based upon the number of months
         worked (rounded-up) during the Plan year.


    G.   Participants must be employed by the Bank, Bank of Tokyo-Mitsubishi
         Group or any subsidiary or affiliate at the time awards are to be paid
         in order to receive payment.  In the case of retirement, death,
         permanent disability, or exceptional circumstances, deviations from
         eligibility due to non-employment at the date of payment may be
         approved at the sole discretion of the President and CEO for non-
         policy making EVPs and eligible SVPs and at the sole discretion of the
         Committee for policy-making officers.

VI. GENERAL PROVISIONS

    A.   NO CONTRACT OF EMPLOYMENT

         Neither the action of Union Bank of California in establishing this
         Plan or its provisions, nor any action taken according to those
         provisions, will be construed as giving the right to a participant to
         continue in the employ of the Bank.  The Plan is not a contract of
         employment.  No rights in the Plan will accrue to any person whether
         or not he/she is selected to participate in the Plan, and no person
         will, because of the Plan acquire any right to an accounting or to
         examine the books or the affairs of the Bank.

    B.   ASSIGNMENT

         No funds, assets or other property of the Bank, and no obligation or
         liability of the Bank under this Plan, will be subject to any claim of
         any participant, nor will any participant have any right or power to
         pledge, encumber or assign any bonus award provided for in this Plan.

    C.   SOLE AND ENTIRE PLAN

         No Bank director, officer, employee or other person has the authority
         to enter into any agreement, either written or oral, with any person
         or participant concerning an award or payment of a bonus award, or to
         make any representation or warranty with respect to any bonus award
         under this Plan.  Only the President and CEO or the Committee, as
         appropriate, will have such authority.  This Plan supersedes any prior
         oral or written understanding on this subject.

                                      BONUS PLAN


    D.   CONTINGENCY

         The Plan is contingent in character and, therefore, no rights will
         vest in any individual participant under the Plan until all conditions
         of the Plan are satisfied.

    E.   MINIMUM PERSONAL PERFORMANCE

         Bank management in its absolute discretion through the President and
         CEO, and in consultation with the Committee where appropriate, retains
         the right to reduce or eliminate incentive awards which are not yet
         paid for a participant whose personal performance level is
         unsatisfactory, regardless of the Bank's or Group's performance.
         Unsatisfactory personal performance shall be determined by the Bank in
         its absolute discretion and may include, but only as examples and not
         as an exhaustive list, such factors as misconduct, poor performance
         rating, poor credit management, poor account management, disruptive
         behavior, failure to adhere to Bank policies and procedures, failure
         to abide by Bank compliance standards, poor audits, failure to control
         or monitor risk, or other relevant factors.

    F.   NO VESTING

         The right to receive any payment of a bonus award shall not vest in
         any employee, or the estate of the employee, until such payment is
         actually made in accordance with the terms and conditions of the Plan.


    G.   ADMINISTRATION

         Bank management shall determine in its absolute discretion all
         elements and goals of the Plan.  All determinations made by the Bank
         shall be binding.  At any time prior to the date the awards are paid,
         the Bank reserves the right to adjust any element or goals of the
         Plan.

                                      BONUS PLAN


    H.   AMENDMENT

         The Bank management may at any time, revise, amend, suspend, or
         terminate in whole or in part, any or all provisions of this Plan.

    I.   OTHER INCENTIVE PLANS

         An individual may not participate in this Plan during the time that
         he/she is participating in any business unit incentive plan.


    J.   TAX RELATED LIABILITIES

         Participants are responsible for determining the tax consequences of
         bonus awards and arranging for appropriate withholding and payment of
         all taxes due.  The Bank will not be responsible for and will be held
         harmless from liability for payments, interest, penalties, costs or
         expenses incurred as a result of not arranging for sufficient
         withholding or deductions from bonus awards.

    K.   ARBITRATION

         This Plan is made, and shall in all respects be interpreted, enforced
         and governed by and under the laws of the United States, as
         appropriate, and the State of California.  Any dispute arising out of
         or relating to this Plan including its meaning or interpretation will
         be resolved solely by arbitration before an experienced employment
         arbitrator selected in accordance with the model employment
         arbitration procedures of the American Arbitration Association.  The
         locations of the arbitration will be in San Francisco, Los Angeles,
         San Diego, Portland or Seattle as selected by the Bank in good faith.
         The provisions of this paragraph are exclusive for all purposes and
         applicable to any and all disputes between a participant and the Plan.
         Any decision or award by an arbitrator shall affect the Plan solely as
         to its obligations to the participant who requests arbitration.  The
         arbitrator's decision will have no impact on the Plan's relationship
         to any other participant, nor will it require the Bank to interpret
         the Plan in any particular manner.

    L.   BENEFITS UNFUNDED AND UNSECURED

         The rights of a participant, or any designated beneficiary of the
         participant, shall be solely those of an unsecured general creditor of
         the Bank, and the Bank's obligation shall be an unfunded and unsecured
         promise to pay.

                                                                December 7, 1995

Mr. Roy Henderson
The Bank of California
400 California Street
San Francisco, California  94104

         Re:  Change of Control Agreement

Dear Roy:

         I am pleased that you have decided to become part of the management
team of the new bank.  As we discussed earlier, I know that your experience and
unique talents will assist us in successfully meeting the challenges of the
merger and the creation of Union Bank of California ("UBOC").

         I have received your letter of September 21, 1995 regarding the terms
you would like to have included as part of your employment relationship with
UBOC.  By this letter, I wanted to memorialize the essential parts of the
agreement we reached regarding your future employment with The Bank of
California and UBOC.  I expect you keep the information contained in this letter
STRICTLY CONFIDENTIAL.

         1.   TITLE.  Your title will be Vice Chairman and, at UBOC, you will
report to me.  We would also like you to be a member of the Executive Management
Committee of UBOC.

         2.   JOB RESPONSIBILITIES.  As a Vice Chairman of UBOC, you will focus
on the Trust, Investment, and Private Banking areas.  We will expect you to
establish a synergy between the retail and small business banking areas that Mr.
Hartnack is expected to manage and with the middle market banking area which
Mr. Walker is expected to manage.

         3.   COMPENSATION THROUGH APRIL, 1996.  Your base salary will remain
the same until your next regularly scheduled increase on April 1.  At that time
you will be

Mr. Roy Henderson
December 7, 1995                                                          Page 2


considered for a merit increase based on your performance.  Short term and long
term incentives for the current year will be paid in accordance with the terms
of the existing plan.  A new competitive short term and long term plan for UBOC
will be introduced in 1996.  Your benefits will remain the same until the merger
date.

         4.   TERMINATION.  As an officer of The Bank of California and, after
the merger, you will be subject to the dismissal provisions of the National Bank
Act.  This means that the Bank can terminate your employment at any time, with
or without cause.  We have agreed that the vote by the Boards of Directors on
September 27, 1995 approving the merger between Union Bank and BanCal Tri-State
Corporation shall be considered a change in control sufficient to trigger that
clause of your contract executed by you on August 13, 1993.  Therefore, in the
event that your employment is terminated by you or the Bank before September 27,
1997, the termination will be treated as a Qualifying Event under your August
13, 1993 contract, and you will receive severance payments pursuant thereto.
If the Bank terminates your employment at any time for willful misconduct or
gross negligence, you will be entitled only to your regular compensation through
the date of your termination.

         5.  UBOC'S EMPLOYMENT CONTRACT.  UBOC will offer you a new employment
contract, which will supersede your August 13, 1993 contract with The Bank of
California referenced above.  You have requested and I have agreed that your new
employment contract will be consistent in terms of benefits and duration with
the employment agreements offered to other Vice Chairman of UBOC, except that
through September 27, 1997 the parachute provision described in paragraph 4.
above will be in effect.

         If the terms proposed in this letter accurately represent the
essential terms of the agreement we have reached, please sign the letter in the
place indicated and return it to me.

         I want to thank you for your continued support and assistance during
this time of transition and change.  I am looking forward to working with you as
we move into the merger and the formation of a strong quality bank.

                                       Very truly yours,

                         DECLARATION OF AMENDMENT AND
                     RESTATEMENT OF THE BANK OF CALIFORNIA
                             NATIONAL ASSOCIATION,
                      EXECUTIVE SUPPLEMENTAL BENEFITS PLAN


    WHEREAS, The Bank of California, a national association organized under 
the laws of the United States and headquartered in San Francisco, California 
(hereinafter called the "Bank") entered into a contract effective as of 
January 1, 1986 establishing a Supplemental Retirement Plan for eligible 
executives known as The Bank of California, National Association Executive 
Supplemental Benefits Plan (the "Plan"), to provide retirement and other 
benefits for such employees of the Bank (and certain of its affiliates and 
subsidiaries) as from time to time may be and become Participants; and

    WHEREAS, the Bank has reserved the right to amend the Plan and desires to 
amend it in certain respects as hereinafter set forth;

    NOW THEREFORE, The Bank of California, National Association Executive 
Supplemental Benefits Plan is hereby amended and restated to read as follows:

                      ARTICLE 1. RESTATEMENT AND PURPOSE
 
    1.1 RESTATEMENT OF PLAN.  The Bank of California, National Association 
(the "Bank") hereby restates, effective as of January 1, 1990, its Executive 
Supplemental Retirement Plan and shall be referred to hereinafter as the 
"Plan."

    1.2 PURPOSE OF THE PLAN.  It is the purpose of this Plan to provide 
eligible executives with benefits that will compensate them for benefits lost 
because of maximums imposed by law upon qualified pension and profit sharing 
plans, and to provide benefits to other eligible executives given deferred 
compensation agreements by the Board of Directors of the Bank. This Plan is 
established in order to provide supplemental retirement benefits, payable as 
provided hereafter solely from the general assets of the Bank. The Plan is 
intended to be exempt from the participation, vesting, funding, and fiduciary 
requirements of Title 1 of the Employee Retirement Income Security Act of

prevented from receiving a full allocation of Employer contributions under 
the Personal Retirement Options Plan as amended ("PRO") and/or Employer 
contributions (other than elective deferrals) under the Capital Accumulation 
Plan as amended ("CAP") due to restrictions imposed by the Internal Revenue 
Code of 1986 as amended ("Code") Section 415 and/or by Section 401(a)(17), or 
successor provisions thereto, shall become a Participant in this Plan 
beginning with the first day of the calendar year in which allocations of 
Employer contributions are limited or reduced under either Plan. Any employee 
of the Employer who is prevented from receiving a full allocation of Employer 
matching contributions under the CAP provisions because of the limitations 
imposed by Code Section 402(g) as adjusted, or successor provisions thereto, on 
the matched elective deferrals shall become a Participant in this Plan 
beginning with the first day of the calendar year for which such allocations 
are limited or reduced. Any Employee who is given a deferred compensation 
agreement by the Board of Directors or its designee shall become a 
Participant as of the first day of the month following the month in which his 
or her participation is approved by the appropriate party.

   3.2 DURATION.  An Employee who becomes a Participant shall remain a 
Participant hereunder until the earliest to occur of (i) his or her 
Retirement, or (ii) the date upon which his or her employment terminates for 
any reason.

                             ARTICLE 4. BENEFITS

   4.1 DEFINED CONTRIBUTION BENEFIT.  For the calendar year 1986 and for each 
calendar year thereafter, the Bank shall credit, as of the end of the 
calendar year, each Participant who qualifies under Article 3 with deferred 
compensation in an amount equal to the amount of Employer contributions 
(excluding elective deferrals under CAP) which would have been allocated to 
his account under CAP and PRO if (i) each Plan lacked provisions designed to 
comply with Internal Revenue Code Section 415, or successor provision thereto, 
(ii) for years 1986 and 1987 the Participant had not entered into an 
irrevocable agreement to defer payment of salary and bonuses, less the amount 
actually allocated to his accounts under such Plans, and (iii) for calendar 
year 1987 and thereafter, the amount of Employer matching contributions which


                                      -3-
<PAGE>

would have been allocated to his account under CAP if the plan did not 
contain provisions designed to comply with Internal Revenue Code section 
402(g), less the Employer contributions (other than elective deferrals under 
CAP) actually allocated to his account under CAP and PRO that year.

   The deferred compensation amounts specified in the preceding sentence 
shall be allocated to the account of a Participant as of the date such 
amounts would have been allocated under the PRO and CAP plans absent such 
Code limitations or, for 1986 and 1987, compensation deferrals.

   4.2 CONTRACT PAYMENTS.  If a Participant has entered into a contract with 
the Employer that promises deferred compensation to the Participant, whether 
in the form of allocations or deferrals to a book reserve account, or in the 
form of monthly payments after separation from service, then such benefits 
will be paid under the provisions of this Plan to the extent that these 
provisions are not inconsistent with the Participant's contract.

If the Participant's contract requires that a book reserve account be 
maintained, then allocations and valuation increases, as well as benefit 
payments, shall be made under this Plan, and shall be administered by the 
Compensation and Benefits Committee. Similarly, if the contract calls for 
deferred payment, the value thereof shall be a liability of this Plan, and the 
payment of benefits shall be administered by the Compensation and Benefits 
Committee.

The Board of Directors shall have the power to determine whether benefits 
required under a separate contract with a Participant shall operate to reduce 
accruals under section 4.1 and the extent of any such reduction.

    4.3 MAINTENANCE OF ACCOUNTS.  

        (a)  The Bank shall establish and maintain, in the name of each 
Participant, an individual account, to be known as the supplemental account, 
which shall be credited each year with any allocation the Participant is 
entitled to receive under section 4.1 (and 4.2 if applicable) and earnings 
or losses on the balance outstanding as of the end of the preceding year.

As of the end of each calendar year, the Compensation and Benefits Committee 
shall adjust the balance, if any, of the Participant's supplemental account 
as of the last day of the preceding calendar year, by multiplying such amount 
by a number equal to one plus the decimal equivalent of the percentage yield, 
as of the first week of the current calendar year, available for new deposits 
made to guaranteed interest contracts under CAP and PRO at such time.

        (b)  The supplemental account of each Participant shall be entered on 
the books of the Bank and shall represent a liability, payable when due under 
this Plan, out of the general assets of the Bank. Prior to benefits becoming 
due hereunder, the Bank shall expense the liability for payment of such 
accounts in accordance with policies determined appropriate by the Bank's 
controller. The supplemental account created for a Participant by the Bank 
shall not be funded by a trust or an insurance contract; nor shall any assets 
of the Bank be segregated or identified to such account; nor shall any


                                      -4-
<PAGE>

property or assets of the Bank be pledged, encumbered, or otherwise subjected 
to a lien or security interest for payment of benefits hereunder.

     4.4 VESTING AND FORFEITURES. A separate accounting shall be kept for 
each Participant of book accruals (and earnings) attributable, under 
section 4.1, to the PRO plan, and each Participant shall attain a 
nonforfeitable right to benefits attributable to such account only to the 
extent that he is "vested" under the PRO plan. The separate accounting 
maintained under this section shall be dropped once the Participant becomes 
fully vested under PRO. The balance of a Participant's supplemental account 
attributable to CAP benefits shall be nonforfeitable at all times. Any 
Participant who has his employment terminated by reason of theft, 
embezzlement, willful misconduct or gross neglect of the employer's policies 
or procedures shall lose any right to a benefit notwithstanding the fact that 
he may have attained a vested interest in that benefit.

     4.5 PAYMENT OF DEFERRED COMPENSATION. The amount accumulated in a 
Participant's supplemental account shall be distributed in a single sum at 
the same time as his distribution from the Personal Retirement Options Plan. 

     4.6 DEATH. The supplemental account of a Participant who dies while 
employed shall be paid in a lump sum to the Participant's Beneficiary at the 
same time as benefits are paid out to the beneficiary designated under the 
Personal Retirement Options Plan.

                             ARTICLE 5.  ADMINISTRATION

     5.1 COMPENSATION AND BENEFITS COMMITTEE. This Plan shall be administered 
by the Employee Compensation and Benefits Committee of the Board of Directors 
of the Bank (the "Committee").  The Committee shall consist of not fewer than 
three (3) members of the Board of Directors of the Bank. The Board of 
Directors may from time to time remove members from, or add members to, the 
Committee. Vacancies on the Committee shall be filled by the Board of 
Directors. No directors, while a Participant in this Plan, shall be eligible 
to serve as a member of the Committee.

The interpretation and construction by the Committee of any provisions of the 
Plan shall be final unless otherwise determined by the Board of Directors. 
Subject to the Board, the Committee is authorized to interpret the Plan, to 
prescribe, amend, and rescind rules and regulations relating to it, to decide 
upon claims pursuant to section 5.5 below, and to make all other 
determinations necessary for its administration.

Without limiting the generality of the foregoing, the Committee shall have 
the authority to calculate pensions and deferred compensation amounts 
allocable to Participants, and to maintain and adjust supplemental accounts. 
The Committee shall have the authority to delegate responsibility for 
performance of ministerial functions necessary for administration of the Plan 
to such officers of the Bank, excluding Participants, as the Committee shall 
in its discretion deem appropriate.

     5.2 UNIFORM RULES. In administering the Plan, the Committee will apply 
uniform rules, policies and procedures to all Participants similarly situated,


                                  -5-
<PAGE>

which uniform rules, policies and procedures shall be maintained by the Bank 
in writing. 

     5.3 NOTICE OF ADDRESS. Any payment to a Participant or Beneficiary, at 
the last known post office address on file with the Bank, shall constitute a 
complete acquittance and discharge to the Bank and any director or officer 
with respect thereto unless the Bank shall have received prior written notice 
of any change in the address, condition, or status of the distributee. 
Neither the Bank nor any director or officer shall have any duty or 
obligation to search for or ascertain the whereabouts of any Participant or 
his Beneficiary.

     5.4 RECORDS. The records maintained by the Bank under the direction of 
the Committee with respect to the Plan shall be conclusive on all 
Participants, all Beneficiaries, and all other persons whomsoever.

     5.5 CLAIMS PROCEDURE. If any claim for benefits under the Plan is wholly 
or partially denied by the Committee, the claimant shall be given notice in 
writing, within a reasonable period of time after receipt of the claim by the 
Plan, by registered or certified mail, of such denial, written in a manner 
calculated to be understood by the claimant, setting forth the specific 
reasons for such denial, specific reference to pertinent Plan provisions on 
which the denial is based, a description of any additional material or 
information necessary for the claimant to perfect the claim and an 
explanation of the Plan's claims review procedure. The claimant also shall be 
advised that he or his duly authorized representative may request a review by 
the Board of Directors of the decision denying the claim by filing with the 
Board, within 65 days after such notice has been received by the claimant, a 
written request for such review, and that he may review pertinent documents, 
and submit issues and comments in writing within the same 65-day period. If 
such request is so filed, such review shall be made by the Board within 60 
days after receipt of such request; and the claimant shall be given written 
notice of the decision resulting from such review, and shall include specific 
reasons for the decision, written in a manner calculated to be understood by 
the claimant, and specific references to the pertinent Plan provisions on 
which the decision is based.

                        ARTICLE 6.  GENERAL PROVISIONS

     6.1 NONASSIGNABILITY. Benefits under the Plan are not in any way subject 
to the debts or other obligations of the persons entitled thereto and may not 
voluntarily or involuntarily be sold, transferred, or assigned. Any voluntary 
attempt to sell, anticipate, assign, or encumber benefits under this Plan 
shall operate to cancel the benefit or the balance of a Participant's 
supplemental account as of the date of such attempt and to relieve the Bank 
from any future liability to pay or distribute any benefit with respect to 
such canceled amount.

     6.2 INCOMPETENCY. Every person receiving or claiming benefits under the 
Plan shall be conclusively presumed to be mentally competent and of age until 
the Compensation and Benefits Committee receives written notice, in a form 
and manner acceptable to it, that such person is incompetent or a minor, and 
that a guardian, conservator, statutory committee, or other person legally 
vested 


                                       -6-
<PAGE>

with the care of his estate has been appointed. In the event that the 
Compensation and Benefits Committee finds that any person to whom a benefit 
is payable under the Plan is unable to properly care for his affairs, or is a 
minor, then any payment due (unless a prior claim therefor shall have been 
made by a duly appointed legal representative) may be paid to the spouse, a 
child, a parent, or a brother or sister, or to any person deemed by the 
Compensation and Benefits Committee to have incurred expense for such person 
otherwise entitled to payment.

     In the event a guardian or conservator or statutory committee of the 
estate of any person receiving or claiming benefits under the Plan shall be 
appointed by a court of competent jurisdiction, payment shall be made to such 
guardian or conservator or statutory committee provided that proper proof of 
appointment is furnished in a form and manner suitable to the Compensation 
and Benefits Committee. Any payment made under the provisions of this section 
shall be a complete discharge of liability therefor under the Plan.

     6.3 EMPLOYMENT RIGHTS. The establishment of the Plan shall not be 
construed as conferring any legal rights upon any Participant or any other 
person for a continuation of employment, nor shall it interfere with the 
rights of the Bank to discharge any person or treat him without regard to the 
effect which such treatment might have upon him as a person covered by this 
Plan.

     6.4 NO INDIVIDUAL LIABILITY. It is declared to be the express purpose 
and intention of the Plan that no liability whatsoever shall attach to or be 
incurred by the shareholders, officers, or directors of the Bank, or any 
representatives appointed hereunder by the Bank, under or by reason of any of 
the terms or conditions of the Plan.

     6.5 ILLEGALITY OF PARTICULAR PROVISION. If any particular provision of 
this Plan shall be found to be illegal or unenforceable, such provision shall 
not affect any other provision thereof, but the Plan shall be construed in 
all respects as if such invalid provision were omitted.

                   ARTICLE 7.  AMENDMENT AND TERMINATION

     7.1 AMENDMENT AND TERMINATION. The Bank expects the Plan to be 
permanent, but since future conditions affecting the Bank cannot be 
anticipated or foreseen, the Bank must necessarily and does hereby reserve 
the right to amend, modify, or terminate the Plan at any time by action of 
its Board of Directors.

     7.2 REORGANIZATION OF THE BANK. In the event of a merger or consolidation 
of the Bank, or the transfer of substantially all of the assets of the Bank 
to another corporation, such continuing, resulting or transferree corporation 
shall have the right to continue and carry on the Plan and to assume all 
liabilities of the Bank hereunder without obtaining the consent of any 
Participant or Beneficiary. If such successor shall assume the liabilities of 
the Bank hereunder, then the Bank shall be relieved of all such liability, 
and no Participant or Beneficiary shall have the right to assert any claim 
against the Bank for benefits under or in connection with this Plan.


                                    -7-
<PAGE>

     7.3 PROTECTED BENEFITS. If the Plan is terminated, or if liabilities 
accrued hereunder up to the date of an event specified in section 7.2 are not 
assumed by the successor to the Bank, then the dollar amount of benefits of 
each retired Participant and Beneficiary and the dollar amount of vested 
benefits of each active Participant shall be guaranteed and shall not 
thereafter be reduced without the Participant's or Beneficiary's consent.

                           ARTICLE 8.  APPLICABLE LAWS

     8.1 APPLICABLE LAWS. The Plan shall be governed by and construed 
according to the laws of the State of California.

must be included in gross income by the taxpayer as compensation for 
services. Therefore, all reimbursements and payments made by the Bank in your

to you if you are entitled to declare a moving expense deduction, and for the 
detailed moving expense information with respect to the deduction, see 
Internal Revenue Service Form 3903 and Publication 521.

TAX REQUIREMENTS: Present federal tax laws require that certain moving 
expenses be treated as income by the employee. In these instances, the Bank 
will scale up the reimbursement to provide for the additional tax. The basis 
for computation of the tax rate shall be your total base salary (excluding 
other income), plus reimbursed moving expenses less an amount for present 
exemptions, and the standard allowance for deductions.

SUBMITTING EXPENSES: All incurred expenses must be submitted in writing to 
the Manager of Payroll/Operations, 400-10, for approval. These submissions 
should follow these guidelines:

     - Expenses must be itemized and submitted with receipts and vouchers.
     - All expenses are charged to the receiving cost center.
     - The department manager is not authorized to approve payment for moving
      expenses.

      into his/her checking account or by check.

TIME LIMIT
