UNIONBANCAL CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

JUNE 30, 1998
(UNAUDITED)

NOTE 1--BASIS OF PRESENTATION AND NATURE OF OPERATIONS

The unaudited consolidated financial statements of UnionBanCal Corporation
and subsidiaries (the Company) have been prepared in accordance with generally
accepted accounting principles (GAAP) for interim financial reporting and the
instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do
not include all of the footnote disclosures necessary for complete financial
statements in conformity with GAAP. The preparation of financial statements in
conformity with GAAP also requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenue and expense during the reporting period. Actual
results could differ from those estimates. These unaudited consolidated
financial statements should be read in conjunction with the audited consolidated
financial statements included in the Company's Form 10-K for the year ended
December 31, 1997.

Certain amounts for prior periods have been reclassified to conform to
current financial statement presentation.

NOTE 2--RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In June 1996, Statement of Financial Accounting Standards (SFAS) No. 125,
"Accounting for Transfers and Servicing of Financial Assets and Extinguishments
of Liabilities", was issued. This Statement establishes standards for when
transfers of financial assets, including those with continuing involvement by
the transferor, should be considered a sale. SFAS No. 125 also establishes
standards for when a liability should be considered extinguished. This Statement
is effective for transfers of assets and extinguishments of liabilities after
December 31, 1996. In December 1996, the Financial Accounting Standards Board
(FASB) reconsidered certain provisions of SFAS No. 125 and issued SFAS No. 127,
"Deferral of the Effective Date of Certain Provisions of FASB Statement No.
125", to defer for one year the effective date of implementation for
transactions related to repurchase agreements, dollar-roll repurchase
agreements, securities lending and similar transactions. Management determined
that the effect of adoption of SFAS No. 125 and SFAS No. 127 on the Company's
financial statements was not material.

In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Related Information", which establishes annual and interim
reporting standards for an enterprise's operating segments and related
disclosures about its products, services, geographic areas, and major customers.
Adoption of this Statement will not impact the Company's consolidated financial
position, results of operations or cash flows, and any effect will be limited to
the form and content of its disclosures. This Statement is effective for fiscal
years beginning after December 15, 1997, with earlier application permitted. The
Company expects to adopt SFAS No. 131 at December 31, 1998.

In February 1998, the FASB issued SFAS No. 132, "Employers' Disclosures
about Pensions and Other Postretirement Benefits". The Standard revises the
disclosure requirements for pensions and other postretirement benefits. Adoption
of this Statement will not impact the Company's consolidated financial position,
results of operations or cash flows, and any effect will be limited to the form
and content of its disclosures. This Statement is effective for fiscal years
beginning after December 15, 1997.

In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities". The Statement will require the Company to
recognize all derivatives on the balance sheet at fair value. Derivatives that
are not hedges must be adjusted to fair value through income. If the derivative

UNIONBANCAL CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

JUNE 30, 1998
(UNAUDITED)

NOTE 2--RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS (CONTINUED)
is a hedge, depending on the nature of the hedge, changes in the fair value of
derivatives will either be offset against the change in fair value of the hedged
assets, liabilities or firm commitments through earnings or recognized in other
comprehensive income until the hedged item is recognized in earnings. The
ineffective portion of the derivative's change in fair value will be immediately
recognized in earnings. This Statement is effective for fiscal years beginning
after June 15, 1999, with earlier application encouraged. The Company expects to
adopt SFAS No. 133 as of January 1, 2000. The Company is in the process of
determining the impact of SFAS No. 133 on the Company's financial statements,
which is not expected to be material.

In March 1998, the American Institute of Certified Public Accountants
(AICPA) issued Statement of Position (SOP) 98-1, "Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use". SOP 98-1 requires the
capitalization of eligible costs of specified activities related to computer
software developed or obtained for internal use. Management believes that the
adoption of SOP 98-1 will not have a material effect on the Company's financial
position or results of operations. The Statement is effective for fiscal years
beginning after December 15, 1998, with earlier adoption encouraged. The Company
expects to adopt SOP 98-1 on January 1, 1999.

In June 1998, the AICPA issued SOP 98-5, "Reporting on the Costs of Start-Up
Activities". SOP 98-5 requires that entities expense start-up costs and
organization costs as they are incurred. Management believes that the adoption
of SOP 98-5 will not have a material effect on the Company's financial position
or results of operations. The Statement is effective for fiscal years beginning
after December 15, 1998, with earlier adoption encouraged. The Company expects
to adopt SOP 98-5 on January 1, 1999.

NOTE 3--EARNINGS PER SHARE

Basic earnings per share (EPS) is computed by dividing net income after
preferred dividends and parent direct interest in bank subsidiary by the
weighted average number of common shares outstanding during the period. Diluted
EPS incorporates the dilutive effect of common stock equivalents outstanding on
an average basis during the period. Stock options are a common stock equivalent.

NOTE 4--COMPREHENSIVE INCOME

In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income", which requires that an enterprise report and display, by major
components and as a single total, the change in its net assets during the period
from non-owner sources. This Statement is effective for fiscal years beginning
after December 15, 1997. The adoption of this Statement in the first quarter of
1998 resulted in a change in the financial statement presentation, but did not
have an impact on the Company's consolidated financial position, results of
operations or cash flows. Certain amounts in the prior period have been
reclassified to conform to the current presentation under SFAS No. 130.

NOTE 5--SUBSEQUENT EVENT

On August 10, 1998, the Company exchanged 3.4 million shares of its common
stock for The Bank of Tokyo-Mitsubishi, Ltd.'s (BTM) 6 percent direct ownership
interest in Union Bank of California, N.A. (the Bank). This share exchange will
result in the Company owning 100 percent of the Bank. In addition, it increases
BTM's ownership percentage of the Company to 82 percent from 81 percent.

The exchange of shares was accounted for as a reorganization of entities
under common control (similar to a business combination under the pooling of
interests method). Accordingly, all historical financial information will be
restated at September 30, 1998 as if the combination had been in effect for all
periods presented.

In order to provide more useful information with regard to this subsequent
event, selected unaudited pro forma consolidated financial data is presented,
giving effect to the August 10, 1998 exchange of 3.4 million shares. On a
consolidated basis, the exchange will not affect total assets, total
liabilities, total shareholders' equity, and regulatory capital ratios.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

INTRODUCTION

UnionBanCal Corporation (UNBC) is a San Francisco, California-based
commercial bank holding company with consolidated assets of $30.9 billion at
June 30, 1998. Based on total assets, UNBC and its consolidated subsidiaries
(the Company) was the third largest bank holding company in California and among
the 30 largest in the United States. At June 30, 1998, the Company operated 241
banking offices in California, 6 banking offices in Oregon and Washington, and
18 overseas facilities. At June 30, 1998, UNBC was 81 percent owned by The Bank
of Tokyo-Mitsubishi, Ltd. (BTM) and 19 percent owned by other shareholders.
UNBC's principal subsidiary, Union Bank of California, N.A. (the Bank), was 94
percent owned by UNBC and 6 percent owned by BTM. (See Note 5 to the Company's
Consolidated Financial Statements for subsequent developments.)

THIS DOCUMENT MAY CONTAIN FORWARD-LOOKING STATEMENTS THAT ARE SUBJECT TO
RISKS AND UNCERTAINTIES THAT COULD CAUSE ACTUAL RESULTS TO DIFFER MATERIALLY
FROM THOSE INDICATED. FOR A DISCUSSION OF FACTORS THAT COULD CAUSE ACTUAL
RESULTS TO DIFFER, PLEASE SEE THE DISCUSSION CONTAINED HEREIN AND IN THE
COMPANY'S PUBLICLY AVAILABLE SECURITIES AND EXCHANGE COMMISSION FILINGS AND
PRESS RELEASES.

The interim financial information should be read in conjunction with the
Company's Form 10-K for the year ended December 31, 1997. Certain amounts for
prior periods have been reclassified to conform to current financial statement
presentation.

SUMMARY

Net income in the second quarter of 1998 was $108.5 million, compared to
$96.5 million in the second quarter of 1997. Net income applicable to common
stock was $102.1 million, or $1.85 per diluted common share, in the second
quarter of 1998, compared with $88.1 million, or $1.60 per diluted common share,
in the second quarter of 1997. Other highlights of the second quarter of 1998
include:

- Net interest income, on a taxable-equivalent basis, was $326.7 million in
the second quarter of 1998, an $18.3 million, or 6 percent, increase from
the comparable period, one year earlier. The increase in net interest
income was primarily due to a 15 basis point increase in the net interest
margin and a $717.9 million, or 3 percent, increase in average earning
assets, resulting primarily from a $1.0 billion, or 5 percent, increase in
average loans, largely funded by an $1.1 billion, or 16 percent, increase
in average noninterest bearing deposits.

- A provision for credit losses of $15.0 million was recorded in the second
quarter of 1998, compared with no provision in 1997. This resulted from
management's regular quarterly assessment of overall credit quality, loan
growth and economic conditions in relation to the level of the allowance
for credit losses. Nonperforming assets declined $53.3 million, or 30
percent, from June 30, 1997 to $122.9 million at June 30, 1998.
Nonperforming assets as a percentage of total assets declined to 0.40
percent at June 30, 1998, compared with 0.58 percent a year earlier. Total
nonaccrual loans at June 30, 1998 and 1997 were $107.0 million and $146.1
million, respectively. The ratio of nonaccrual loans to total loans
declined from 0.66 percent to 0.47 percent.

- Noninterest income was $148.0 million, an increase of $37.0 million, or 33
percent, over the second quarter of 1997. Service charges on deposit
accounts grew $4.2 million, or 15 percent, reflecting growth in average
deposits; trust and investment management fees increased $4.3 million, or
17 percent, on growth in assets under management; and other noninterest
income increased $6.7 million, or 61 percent, excluding the $17.1 million
gain from the sale of the $253 million credit card portfolio in April
1998. The increase is due primarily to a $4.8 million gain from the sale
of $123.0 million in commercial real estate loans.

- Noninterest expense was $277.3 million in the second quarter of 1998,
compared with $255.8 million in the second quarter of 1997, an increase of
$21.6 million, or 8 percent. Personnel-related expense increased $14.9
million, or 11 percent, primarily due to increases in salaries and
performance-based

incentive compensation. Other noninterest expense increased $5.3 million,
or 29 percent, primarily attributable to additional expenses incurred to
support higher deposit and merchant credit card draft volumes.

- The effective tax rate for the second quarter of 1998 was 40 percent,
compared with 41 percent for the second quarter of 1997. The lower
effective tax rate in the second quarter of 1998 reflects the benefits
recognized from filing a California Franchise Tax return based on the
unitary concept, which incorporates the financial results of BTM.

- In the second quarter of 1998, the return on average assets increased to
1.46 percent from 1.32 percent a year earlier. The return on average
common equity was 15.50 percent at June 30, 1998, compared to 15.16
percent at June 30, 1997.

- Total loans at June 30, 1998 increased $829.2 million, or 4 percent, over
June 30, 1997, primarily due to growth in the commercial, financial and
industrial portfolio.

- The Company's Tier 1 and total risk-based capital ratios were 9.28 percent
and 11.34 percent at June 30, 1998, compared with 9.19 percent and 11.59
percent at June 30, 1997. The second quarter 1998 leverage ratio for the
Company was 9.27 percent, compared with 8.68 percent for the second
quarter of 1997.

Net income for the first six months of 1998 was $204.1 million, compared to
$189.0 million for the first six months of 1997. Net income applicable to common
stock was $192.1 million, or $3.48 per diluted common share, for the first six
months of 1998, compared with $172.4 million, or $3.14 per diluted common share,
for the first six months of 1997. Other highlights of the first half of 1998
include:

- Net interest income, on a taxable-equivalent basis, was $645.4 million for
the first six months of 1998, a $41.5 million, or 7 percent, increase from
the comparable period one year earlier. The increase in net interest
income was primarily due to a 16 basis point increase in the net interest
margin and an $885.3 million, or 3 percent, increase in average earning
assets, resulting primarily from a $1.2 billion, or 6 percent, increase in
average loans and largely funded by a $1.1 billion, or 15 percent,
increase in average noninterest bearing deposits.

- A provision for credit losses of $35.0 million was recorded for the first
six months of 1998, compared with no provision in 1997. This resulted from
management's regular quarterly assessment of overall credit quality, loan
growth and economic conditions in relation to the level of the allowance
for credit losses.

- Noninterest income was $276.0 million, an increase of $50.2 million, or 22
percent, over the first six months of 1997. This increase includes the
$17.1 million gain from the sale of the credit card portfolio in the
second quarter of 1998. Service charges on deposit accounts grew $10.2
million, or 18 percent, reflecting growth in average deposits; trust and
investment management fees increased $8.4 million, or 17 percent, on
growth in assets under management; international commissions and fees
increased $4.2 million; and securities gains, net increased $4.4 million.

- Noninterest expense was $545.8 million for the first six months of 1998,
compared with $508.9 million for the first six months of 1997, an increase
of $36.9 million, or 7 percent. Personnel-related expense increased $24.5
million, or 9 percent, primarily due to an increase in salaries, related
to merit increases and business related staff additions, and
performance-based incentive compensation. Other noninterest expense
increased $12.1 million, or 36 percent, primarily attributable to
additional expenses incurred to support higher deposit volumes.

- The effective tax rate for the first six months of 1998 was 40 percent,
compared with 41 percent for the first six months of 1997.

- The return on average assets for the first six months of 1998 increased to
1.38 percent, compared to 1.31 percent for the first six months of 1997.
The return on average common equity decreased to 14.88 percent for the
first six months of 1998, compared to 15.14 percent for the first six
months of 1997.

(1) Yields and interest income are presented on a taxable-equivalent basis
using the federal statutory tax rate of 35 percent.

(3) Foreign loans and deposits are those loans and deposits originated in
foreign branches.

(4) Yields on securities available for sale are based on fair value. The
difference between these yields and those based on amortized cost was not

Net interest income is interest earned on loans and investments less
interest expense on deposit accounts and borrowings. Primary factors affecting
the level of net interest income include the margin between the yield earned on
interest earning assets and the rate paid on interest bearing liabilities, as
well as the volume and composition of average interest earning assets and
average interest bearing liabilities.

Net interest income, on a taxable-equivalent basis, was $326.7 million for
the second quarter of 1998, compared with $308.4 million for the second quarter
of 1997. This increase of $18.3 million, or 6 percent, was primarily
attributable to a $717.9 million, or 3 percent, increase in average earning
assets largely funded by a $1.1 billion, or 16 percent, increase in average
noninterest bearing deposits. In addition, the net interest margin increased 15
basis points to 4.90 percent. Although the yield on average earning assets
declined more than the rate on average interest bearing liabilities, the
increase in the proportion of funding provided by noninterest bearing deposits,
which lowered the overall cost of funds, favorably impacted the net interest
margin.

Average earning assets were $26.7 billion in the second quarter of 1998,
compared with $26.0 billion in the second quarter of 1997. Most of this increase
was attributable to growth in average loans, which increased $1.0 billion, or 5
percent, and average securities, which were $502.5 million, or 19 percent,
higher, offset by a $940.9 million decrease in average interest bearing deposits
in banks. The growth in average loans was attributable to the increase in
average commercial, financial and industrial loans of $1.3 billion and the
increase in average commercial mortgage loans of $210.7 million, partly offset
by the decrease in average consumer loans of $396.3 million, primarily related
to the sale of the credit card portfolio. See "Loans" on page 23 for additional
commentary on growth in the loan portfolio. The increase in primarily fixed rate
securities reflected interest rate risk management actions to reduce the
Company's exposure to declines in interest rates, and, secondarily, to increase
liquidity.

The $717.9 million, or 3 percent, growth in average earning assets from the
second quarter of 1997 to the second quarter of 1998 was funded primarily by a
$1.1 billion increase in average noninterest bearing deposits. The increase in
noninterest bearing deposits was partially due to an influx of new customer
relationships, arising from the recent merger and acquisition activities of
other financial institutions in the California market during the past year.

For the first six months of 1998, net interest income, on a taxable
equivalent basis, was $645.4 million, compared with $603.9 million in the
comparable period one year earlier. The increase of $41.5 million, or 7 percent,
was primarily attributable to an $885.3 million, or 3 percent, increase in
average earning assets and a $1.1 billion, or 15 percent, increase in average
noninterest bearing deposits. In addition, the net interest margin increased 16
basis points to 4.88 percent. Although the yield on average earning assets
declined by 3 basis points and the rate on interest bearing liabilities
increased by 1 basis point, the negative impact on the net interest margin of
these two factors was more than offset by the increase in the proportion of
funding provided by noninterest bearing deposits.

In the second quarter of 1998, noninterest income was $148.0 million,
compared with $111.0 million for the same period in 1997. This increase of $37.0
million, or 33 percent, includes a $17.1 million gain from the sale of the
credit card portfolio, a $4.2 million increase in service charges on deposit
accounts, reflecting a 2 percent increase in average deposits coupled with the
expansion of several products and services, and a $4.3 million increase in trust
and investment management fees, largely due to growth of assets under
management. In addition, other noninterest income increased $6.7 million, or 61
percent, due primarily to a $4.8 million gain related to the sale of $123.0
million in commercial real estate loans.

For the first six months of 1998, noninterest income was $276.0 million,
compared with $225.8 million for the same period in 1997. This increase of $50.2
million, or 22 percent, includes the second-quarter gain of $17.1 million from
the sale of the credit card portfolio, a $10.2 million increase in service
charges on deposit accounts, reflecting a 3 percent increase in average deposits
coupled with the expansion of several products and services; an $8.4 million
increase in trust and investment management fees, largely due to growth of
assets under management; a $4.2 million increase in international commissions
and fees; a $4.4 million increase in securities gains, net; and a $5.0 million
increase related to brokerage commissions and merchant banking fees. In
contrast, other noninterest income decreased $1.9 million, or 6 percent, due to
a $7.7 million gain recognized in 1997 related to a real estate joint venture,
partially offset by the $4.8 million gain in 1998 from the sale of commercial
real estate loans.

Noninterest expense was $277.3 million in the second quarter of 1998,
compared with $255.8 million in the second quarter of 1997, an increase of $21.6
million, or 8 percent. Personnel-related expense increased $14.9 million, or 11
percent, primarily due to a $5.4 million increase in performance-based incentive
compensation, and an increase of $6.2 million in salaries, related to merit
increases and a 4 percent increase in workforce, to support increased revenue
growth. In addition, other noninterest expense increased $5.3 million, partially
due to $2.9 million in additional expenses incurred to support higher deposit
volumes.

Noninterest expense was $545.8 million for the first six months of 1998,
compared with $508.9 million for the first six months of 1997, an increase of
$36.9 million, or 7 percent. Personnel-related expense increased $24.5 million,
or 9 percent, primarily due to increases in performance-based incentive
compensation and salaries, reflecting a 4 percent increase in the workforce. In
addition, other noninterest expense increased $12.1 million, partially due to
$5.3 million in additional expenses incurred to support higher deposit volumes.

The combination of Union Bank and BanCal Tri-State Corporation on April 1,
1996 resulted in the recording of a total of $123.5 million in merger and
integration expense. The remaining liability balance at June 30, 1998 was $11.9
million. The balance includes amounts primarily for lease payments that are
continuing over the expected term of the leases. No merger and integration
expense was recorded for the first six months of 1998, compared with $6.0
million for the first six months of 1997.

YEAR 2000

The Year 2000 problem exists because many computer programs use only the
last two digits to refer to a year. This convention could affect date-sensitive
calculations that treat "00" as the year 1900, rather than 2000. An additional
issue is that 1900 was not a leap year, whereas the year 2000 is. Therefore,
some programs may not properly provide for February 29, 2000. This anomaly could
result in miscalculations when processing critical date-sensitive information
after December 31, 1999.

The following discussion of the implications of the Year 2000 problem for
the Company contains numerous forward-looking statements based on inherently
uncertain information. The cost of the project and the date on which the Company
plans to complete the internal Year 2000 modifications are based on management's
best estimates, which were derived utilizing a number of assumptions of future
events including the continued availability of internal and external resources,
third party modifications and other factors. However, there can be no guarantee
that these estimates will be achieved and actual results could differ. Moreover,
although Management believes it will be able to make the necessary modifications
in advance, there can be no guarantee that failure to modify the systems would
not have a material adverse affect on the Company.

In addition, the Company places a high degree of reliance on computer
systems of third parties, such as customers, suppliers, and other financial and
governmental institutions. Although the Company is assessing the readiness of
these third parties and preparing contingency plans, there can be no guarantee
that the failure of these third parties to modify their systems in advance of
December 31, 1999 would not have a material adverse affect on the Company.

READINESS PREPARATION

Many of the Company's critical operations are not presently ready to operate
normally in the Year 2000 and beyond, although preparations are underway to
correct this. In 1997 the Company alerted its business customers of the Year
2000 problem and is now assessing the readiness preparations of its major
customers and suppliers. Resolution of the Year 2000 problem is among the
Company's highest priorities, and a comprehensive program has been established
to address its many aspects.

The Company has prepared a project plan, identified all of its major
application and processing systems, and sought external and internal resources
to replace and test the systems. Purchased software and systems supported by
external parties will be tested as part of the formal project plan. In addition,
customers and vendors who have significant relationships with the Company will
be evaluated to determine whether they are preparing for the Year 2000. The
failure of those customers to adequately prepare will be incorporated into the
credit review process. However, there can be no guarantee that the remediation
of the systems of the Company's vendors or customers will be corrected on a
timely basis.

The Company's Year 2000 program is comprised of numerous individual projects
which address the following broad areas: data processing systems,
telecommunications and data networks, building facilities and security systems,
vendor risk, customer risk, contingency planning, and communications. As of June
30, 1998, there were approximately 2,100 individual projects identified. The
projects vary in size, importance and materiality: from large undertakings, such
as remediating complicated data systems and organizing the process of assessing
the readiness of customers, to smaller, but still important, projects such as
installing compliant computer utility systems or assuring that
processor-controlled systems in individual buildings will perform properly. The
program continues to evolve as new projects are identified to keep up with
increased understanding of Year 2000 implications and evolving external
requirements. Approximately two thirds of the projects currently identified are
in process, while almost a third have been completed.

All projects are assigned a priority indicating the importance of the
function to the Company's continuing operation. This prioritization allows for
the broad classification of the projects into critical and

non-critical categories. "Critical projects" are currently defined as those that
meet any of the following criteria:

- functions the absence of which for longer than three days could threaten
the operations of the Company;

- customer and general ledger accounting systems of record;

- functions supporting delivery of information and service to customers;

- administrative systems, which if unavailable for two weeks or longer,
could cause significant business impact; or

- functions that provide the environment and infrastructure necessary for
the above.

Of the approximately 2,100 total projects, nearly 40 percent are currently
identified as critical and 60 percent as non-critical.

The Company plans to complete all projects currently identified as critical
prior to the year 2000, although the failure to complete a critical project
would not necessarily have a material adverse effect on the Company. The most
important projects relate to the critical data processing systems upon which the
Company relies for its principal business functions. Most of these systems are
presently being renovated. The Company expects to have substantially all of
these systems renovated and tested by December 31, 1998. All critical systems
are planned to be renovated, tested and implemented prior to June 30, 1999. In
addition to testing individual systems, the Company also plans to conduct
integrated contingency testing of its principal critical systems during the
summer of 1999 in a separate computer environment where machine dates will be
set forward in order to identify and correct problems which might not otherwise
become evident until the actual end of the century.

The Company does not significantly rely on embedded technology in its
critical processes. Embedded technology does control some building security and
operations such as power management, ventilation, and elevator control. All
building facilities are presently being evaluated, and plans call for all to be
confirmed as Year 2000 ready by December 1998.

The Company is reliant on suppliers and customers, and Year 2000 issues with
both groups are being addressed. As of June 30, 1998, over 300 critical vendors
have been identified and inquiries are underway regarding their Year 2000
readiness plans and status. Written risk assessments will be completed on each
and those found to pose a significant risk will be asked to demonstrate how that
risk will be addressed. Appropriate measures to minimize risk will be undertaken
with those that appear to pose a significant risk. Risk assessments on the
critical vendors are scheduled to be completed by November 1998, and
replacements effected where necessary by June 1999. The company, however, has no
viable alternatives for some suppliers, such as power distribution and local
telephone companies. These companies are still being evaluated and the results
will be used as information for contingency planning. As with all financial
institutions, the Company places a high degree of reliance on the systems of
other institutions, including governmental agencies, to settle transactions.
Principal settlement methods associated with major payment systems will be
tested as part of their associated system projects.

The Company is also reliant on its customers to make the necessary
preparations for Year 2000 so that their business operations will not be
interrupted, thus threatening their ability to honor their financial
commitments. As of June 30, 1998, over 2,000 borrowers, capital market
counterparties, funding sources, and large depositors have been identified as
having financial volumes sufficiently large to warrant inquiry as to their Year
2000 preparation. These inquiries are presently underway and written risk
assessments will be completed on each. An initial assessment of risk based on
these assessments is expected to be substantially completed by September 30,
1998. Customers found to have a significant risk of not being ready for Year
2000 will be encouraged to make the necessary effort. Appropriate measures to
minimize risk will be undertaken with those that appear to pose a significant
risk.

COST

Of the currently estimated total project cost of approximately $50 million,
the remaining amount to be incurred for the Year 2000 project is approximately
$43 million and will be funded by normal operating cash and staffed by external
resources as well as internal staff re-deployed from less time-sensitive
assignments. Approximately $11 million of the remaining cost is attributable to
the purchase of new hardware and software, which will be capitalized and
expensed over the useful lives of those assets. The remaining $32 million, which
will be expensed as incurred over the next two years, is not expected to have a
material effect on the results of operations, liquidity or capital resources.
During the second quarter of 1998, the Company incurred and expensed
approximately $3 million related to its assessment of the Year 2000 issue and
its efforts in implementing the Year 2000 project plan. The second-quarter
increase in the total estimated project cost relates primarily to the expanded
scope of the project such as vendor assessments and contingency planning.
Estimated total project cost could change further as analysis continues.

RISKS

The principal risks associated with the Year 2000 problem can be grouped
into three categories. The first is the risk that the Company does not
successfully ready its operations for the next century. The second is the risk
of disruption of Company operations due to operational failures of third
parties. The third is the risk of business interruption among fund providers and
obligors such that expected funding and repayment does not take place.

The only risk largely under the Company's control is preparing its internal
operations for the Year 2000. The Company, like other financial institutions, is
heavily dependent on its computer systems. The complexity of these systems and
their dependence on one another makes it impossible to switch to other systems
almost immediately as would be necessary if necessary corrections were not made
in advance. Management believes it will be able to make the necessary
corrections in advance.

Computer failure of third parties may jeopardize Company operations, but how
seriously depends on the nature and duration of such failures. The most serious
impact on Company operations from suppliers would result if basic services such
as telecommunications, electric power suppliers, and services provided by other
financial institutions and governmental agencies were disrupted. Significant
public disclosure of the state of readiness among basic infrastructure and other
suppliers has not generally been available. Although the Company's inquiries are
underway, the Company does not yet have the information to estimate the
likelihood of significant disruptions among its suppliers.

Operational failures among the Company's sources of major funding, larger
borrowers and capital market counterparties could affect their ability to
continue to provide funding or meet obligations when due. Similar to the
situation outlined above with suppliers, public information has been scant.
Although the Company's inquiries are underway, the Company does not yet have the
information to estimate the likelihood of significant disruptions among its
funding sources and obligors.

CONTINGENCY PLANS

The Company is developing remediation contingency plans and business
resumption contingency plans specific to the Year 2000. Remediation contingency
plans address the actions to be taken if the current approach to remediating a
system is falling behind schedule or otherwise appears in jeopardy of failing to
deliver a Year 2000 ready system when needed. Business resumption contingency
plans address the actions that would be taken if critical business functions can
not be carried out in the normal manner upon entering the next century due to
system or supplier failure.

Remediation contingency plans with trigger dates for review and
implementation have been developed for critical data systems. The effort to
develop business resumption contingency plans, however, is just now beginning.
The first two phases of this effort, Organizational Planning Guidelines and
Business Impact Analysis, are scheduled to be completed by September 30, 1998.
The third and fourth phases, Plan Development and Method for Validation of
Plans, are to be completed by December 31, 1998.

INCOME TAX EXPENSE

The effective rates for the second quarter of 1998 and 1997 were 40 percent
and 41 percent, respectively. The effective tax rates for the six months ended
June 30, 1998 and 1997, were 40 percent and 41 percent, respectively. The lower
effective tax rate in the first quarter and first six months of 1998 reflects
the benefits recognized from filing a California Franchise Tax return based on
the unitary concept, which incorporates the financial results of BTM.

nm = not meaningful

The Company's lending activities are predominantly domestic, with such loans
and leases comprising 94 percent of the portfolio at June 30, 1998. Total loans
at June 30, 1998 were $23.0 billion, an increase of $829.2 million, or 4
percent, from June 30, 1997. The increase was primarily attributable to growth
in the commercial, financial and industrial loan portfolio, which increased $1.2
billion from June 30, 1997, partly offset by the consumer loan portfolio, which
decreased $454.6 million.

Commercial, financial and industrial loans represent the largest category in
the loan portfolio. These loans are extended principally to major corporations,
middle market businesses, and small businesses, with no industry concentration
exceeding 10 percent of total commercial, financial and industrial loans. At
June 30, 1998 and 1997, the commercial, financial and industrial loan portfolio
was $11.6 billion, or 50 percent of total loans, and $10.4 billion, or 47
percent of total loans, respectively. The increase of $1.2 billion, or 11
percent, from June 30, 1997 was primarily attributable to continued growth in
loans extended to large corporations.

The construction loan portfolio totaled $377.5 million, or 2 percent of
total loans, at June 30, 1998, compared with $319.4 million, or 1 percent of
total loans, at June 30, 1997.

Mortgage loans were $5.7 billion, or 25 percent of total loans, at June 30,
1998, compared with $5.8 billion, or 26 percent of total loans, at June 30,
1997. The mortgage loan portfolio consists of loans on commercial and industrial
projects and loans secured by one to four family residential properties,
primarily in California. Despite the sale of $123.0 million in commercial real
estate mortgages, commercial mortgage loans increased $68.6 million from June
30, 1997 to June 30, 1998, primarily attributable to the favorable California
real estate market coupled with the continuing improvement in the West Coast
economy. Residential mortgage loans decreased $116.1 million due to prepayments
and to loan sales into the secondary market.

Consumer loans totaled $2.9 billion, or 13 percent of total loans, at June
30, 1998, compared with $3.4 billion, or 15 percent of total loans, at June 30,
1997. The decrease of $454.6 million was attributable to the sale of the $253.0
million credit card loan portfolio in April 1998, and to a reduction in home
equity loans as customers refinanced to take advantage of favorable long-term,
fixed rate mortgages.

Lease financing totaled $941.7 million, or 4 percent of total loans, at June
30, 1998, compared with $857.9 million, or 4 percent of total loans, at June 30,
1997.

Loans originated in foreign branches totaled $1.4 billion, or 6 percent of
total loans, at June 30, 1998 and $1.4 billion, or 6 percent of total loans, at
June 30, 1997.

CROSS-BORDER OUTSTANDINGS

The Company's cross-border outstandings reflect certain additional economic
and political risks that are not reflected in domestic outstandings. These risks
include those arising from exchange rate fluctuations and restrictions on the
transfer of funds. The following table sets forth the Company's cross-border
outstandings as of June 30, 1998, December 31, 1997, and June 30, 1997 for each
country where such outstandings exceeded 1 percent of total assets. The
cross-border outstandings were compiled based upon category and domicile of
ultimate risk and are comprised of balances with banks, trading account assets,
securities available for sale, securities purchased under resale agreements,
loans, accrued interest receivable, acceptances outstanding and investments with
foreign entities. The amounts outstanding for each country exclude local
currency outstandings. The Corporation does not have significant local currency
outstandings to the individual countries listed in the following table that are
not hedged or are not funded by local currency borrowings.

The economic condition and the ability of some countries, to which the
Company has cross-border exposure, to manage their external debt obligations
have been impacted by the Asian economic crisis which began in the second half
of 1997. Total outstandings as of June 30, 1998 in Japan, Korea and Thailand
were $506 million, $512 million, and $192 million, respectively. The Company's
outstandings in Indonesia, a country which continues to be affected by economic
and political turmoil, were $17 million. In light of events since year-end,
Management believes these short-term exposures can be characterized as low to
moderate risk, depending on the obligor and country.

Since Japan is the second largest trading nation in the world, its
political, economic and financial markets situation is being closely monitored.
Management is also aware that the potential impact of the Asian crisis and the
depressed conditions in Japan on the American economy and Asian companies doing
business with and in the USA, particularly California, are not yet fully
understood. Accordingly, the Company will continue to evaluate the impact that
these conditions may have on the overall portfolio throughout 1998.

Although management cannot predict the ultimate impact of the crisis on the
Company's financial position and results of operations since much depends on the
effect of the stabilizing activities already under way, management believes that
the continuation of internal supervision, monitoring and portfolio risk
management practices will be effective in minimizing the impact over and above
that already identified. Increases in nonaccrual loans, together with some
related increases in charge-off activity, may occur as events unfold.

ALLOWANCE FOR CREDIT LOSSES

The allowance for credit losses is maintained at a level considered
appropriate by management and is based on an ongoing assessment of risk in the
credit and lease portfolio, including commitments to provide financing. The
allowance is increased by the provision for credit losses, which is charged
against current period operating results, and is decreased by the amount of net
loans charged off during the period. In evaluating the adequacy of the allowance
for credit losses, management incorporates such factors as collateral value,
portfolio composition and concentration, and trends in local, national, and
international economic conditions and the related impact on the financial
strength of the Company's borrowers. While the allowance is segmented by broad
portfolio categories to analyze its adequacy, the allowance is general in nature
and is available for the portfolio in its entirety. Although management believes
that the allowance for credit losses is adequate in the second quarter of 1998,
future provisions will be subject to continuing evaluation of risk in the credit
and lease portfolio.

The table below sets forth a reconciliation of changes in the allowance for
credit losses.

(nm) = not meaningful

At June 30, 1998, the Company's allowance for credit losses was $478.1
million, or 2.08 percent of total loans, and 446.7 percent of total nonaccrual
loans, compared with an allowance for credit losses at June 30, 1997 of $502.1
million, or 2.27 percent of total loans, and 343.6 percent of total nonaccrual
loans.

During the second quarter of 1998, the Company recorded a $15.0 million
provision for credit losses, compared with no provision for credit losses in the
second quarter of 1997. This resulted from management's regular quarterly
assessment of overall credit quality, loan growth and economic conditions in
relation to the level of the allowance for credit losses. Future quarterly
provisions will be subject to the same evaluation process.

During the second quarter of 1998, net loans charged off were $2.8 million,
compared with $20.7 million in the second quarter of 1997. Loans charged off in
the second quarter of 1998 decreased by $13.8 million primarily due to a $5.4
million decrease in commercial, financial and industrial loans charged off and a
$6.9 million decrease in consumer loans charged off primarily due to the sale of
the credit card portfolio in April of 1998. Recoveries of loans previously
charged off increased by $4.1 million, and the percentage of loans charged off
to average loans decreased from 0.38 percent in the second quarter of 1997 to
0.05 percent in the second quarter of 1998.

The Company evaluates its loan portfolio for impairment as defined by SFAS
No. 114, "Accounting by Creditors for Impairment of a Loan", as amended. At June
30, 1998, total impaired loans were $107.0 million and the associated impairment
allowance was $15.1 million, compared with total impaired loans of $145.0
million and an associated impairment allowance of $10.0 million at June 30,
1997.

At June 30, 1998, nonperforming assets totaled $122.9 million, a decrease of
$53.3 million, or 30 percent, from a year earlier. The decrease was primarily
the result of reductions of $18.2 million in nonaccrual commercial, financial
and industrial loans, mostly from loans to large corporate borrowers; $15.4
million in nonaccrual commercial mortgage loans due to a combination of note
sales, repayments and restorations to accrual; $14.2 million in foreclosed
assets due to sales of individual assets; and $4.4 million in nonaccrual
construction loans.

Nonaccrual loans as a percentage of total loans were 0.47 percent at June
30, 1998, compared with 0.66 percent at June 30, 1997. Nonperforming assets as a
percentage of total loans and foreclosed assets were 0.54 percent at June 30,

LIQUIDITY

Liquidity refers to the Company's ability to adjust its future cash flows to
meet the needs of depositors and borrowers and to fund operations on a timely
and cost-effective basis. The Company's liquidity

management draws upon the strengths of its extensive retail and commercial
market business franchise, coupled with its ability to obtain funds for various
terms in a variety of domestic and international money markets.

Core deposits provide the Company with a sizable source of relatively stable
and low-cost funds. In the second quarter of 1998, lower cost sources of funds,
which include noninterest bearing deposits and interest bearing core deposits,
funded 64 percent of average earning assets. Most of the remaining funding was
provided by short-term borrowing in the form of negotiable certificates of
deposit, foreign deposits, federal funds purchased and securities sold under
repurchase agreements, commercial paper, and other borrowings.

ratio at June 30, 1998 increased 9 basis points to 9.28 percent, the total
risk-based capital ratio decreased 25 basis points to 11.34 percent, and the
leverage ratio increased 59 basis points to 9.27 percent. The increase in the
Tier 1 risk-based capital ratio was primarily attributable to retained earnings
growing faster than risk-weighted assets, partly offset by the redemption of
$135.0 million of preferred stock in the third quarter of 1997. The decline in
the total risk-based capital ratio was primarily attributable to the reduction
of $134.0 million in subordinated capital notes.

As of June 30, 1998, management believes the capital ratios of the Bank met
all regulatory minimums of a "well-capitalized" institution.

ITEM 3. MARKET RISK

The Company's exposure to market risk is discussed on pages 46-49 of the
