                                     PART I
 
ITEM 1. BUSINESS.
 
    First Empire State Corporation ("Registrant" or "First Empire") is a New
York business corporation which is registered as a bank holding company under
the Bank Holding Company Act of 1956, as amended ("BHCA") and under Article
III-A of the New York Banking Law ("Banking Law"). The principal executive
offices of the Registrant are located at One M&T Plaza, Buffalo, New York 14240.
The Registrant was incorporated in November 1969. The Registrant and its direct
and indirect subsidiaries are collectively referred to herein as the "Company".
As of December 31, 1997, the Company had consolidated total assets of $14.0
billion, deposits of $11.2 billion and stockholders' equity of $1.0 billion. The
Company had 4,359 full-time and 724 part-time employees as of December 31, 1997.
 
    At December 31, 1997, the Registrant had two wholly owned bank subsidiaries:
Manufacturers and Traders Trust Company ("M&T Bank") and M&T Bank, National
Association ("M&T Bank, N.A."). The banks offer a wide range of commercial
banking, trust and investment services to their customers. The East New York
Savings Bank ("East New York"), formerly a wholly owned savings bank subsidiary
of the Registrant, was merged with and into M&T Bank on May 24, 1997. At
December 31, 1997, M&T Bank represented 95% of consolidated assets of the
Company.
 
    On October 28, 1997, First Empire entered into a definitive agreement with
ONBANCorp, Inc. ("ONBANCorp"), a bank holding company headquartered in Syracuse,
New York, for a merger between the two companies. ONBANCorp operates two wholly
owned banking subsidiaries, OnBank & Trust Co., which has 59 offices in upstate
New York, and Franklin First Savings Bank in Wilkes-Barre, Pennsylvania, which
has 19 offices in northeastern Pennsylvania. Upon consummation of the merger,
the banking subsidiaries of ONBANCorp will be merged into M&T Bank. At December
31, 1997, ONBANCorp had $5.3 billion of assets. The merger, which will be
accounted for as a purchase, is subject to a number of conditions, including the
approval of stockholders of both companies, and is currently expected to be
consummated on or about April 1, 1998. Under the terms of the merger agreement,
stockholders of ONBANCorp will have the option to receive .161 of a share of
First Empire common stock (and cash in lieu of any fractional share) or $69.50
in cash in exchange for each share of ONBANCorp common stock. The merger
agreement provides that a minimum of 60% and a maximum of 70% of the total
number of shares of ONBANCorp common stock issued and outstanding immediately
prior to the merger will be exchanged for shares of First Empire common stock.
In the event that ONBANCorp's stockholders as a whole elect to receive stock
consideration with respect to fewer than 60% or more than 70% of the total
number of outstanding shares of ONBANCorp common stock, the selection by
ONBANCorp's common stockholders of the method of payment is subject to
allocation and proration to ensure that the number of shares of ONBANCorp common
stock that are converted into shares of First Empire common stock will be not
less than 60% nor more than 70%, as the case may be, of the total number of
shares of ONBANCorp common stock issued and outstanding immediately prior to the
merger. At February 3, 1998 ONBANCorp had 12,712,196 shares of common stock
issued and outstanding. The merger is subject to the approval of stockholders of
both companies and is expected to be completed on or about April 1, 1998.
 
    The Company from time to time considers acquiring banks, thrift
institutions, branch offices or other businesses within markets currently served
or in other nearby markets. The Company has pursued acquisition opportunities in
the past, continues to review different opportunities, including the possibility
of major acquisitions, and intends to continue this practice.

                           SUPERVISION AND REGULATION
 
    The banking industry is subject to extensive state and federal regulation
and continues to undergo significant change. In 1991, the Federal Deposit
Insurance Corporation Improvement Act ("FDICIA") was enacted. FDICIA
substantially amended the Federal Deposit Insurance Act ("FDI Act") and certain
other statutes. Since FDICIA's enactment, the federal bank regulatory agencies
have adopted regulations to implement its statutory provisions.
 
    The following discussion summarizes certain aspects of the banking laws and
regulations that affect the Company. Proposals to change the laws and
regulations governing the banking industry are frequently raised in Congress, in
state legislatures, and before the various bank regulatory agencies. The
likelihood and timing of any changes and the impact such changes might have on
the Company are impossible to determine with any certainty. A change in
applicable laws or regulations, or a change in the way such laws or regulations
are interpreted by regulatory agencies or courts, may have a material impact on
the business, operations and earnings of the Company. To the extent that the
following information describes statutory or regulatory provisions, it is
qualified entirely by reference to the particular statutory or regulatory
provision.
 
                        BANK HOLDING COMPANY REGULATION
 
    As a registered bank holding company, the Registrant and its nonbank
subsidiaries are subject to supervision and regulation under the BHCA by the
Board of Governors of the Federal Reserve System ("Federal Reserve Board") and
the New York State Banking Superintendent ("Banking Superintendent"). The
Federal Reserve Board requires regular reports from the Registrant and is
authorized by the BHCA to make regular examinations of the Registrant and its
subsidiaries.
 
                                       8



    Under the BHCA, the Registrant may not acquire direct or indirect ownership
or control of more than 5% of the voting shares of any company, including a
bank, without the prior approval of the Federal Reserve Board, except as
specifically authorized under the BHCA. The Registrant is also subject to
regulation under the Banking Law with respect to certain acquisitions of
domestic banks. Under the BHCA, the Registrant, subject to the approval of the
Federal Reserve Board, may acquire shares of non-banking corporations the
activities of which are deemed by the Federal Reserve Board to be so closely
related to banking or managing or controlling banks as to be a proper incident
thereto.
 
    The Federal Reserve Board has enforcement powers over bank holding companies
and their non-banking subsidiaries, among other things, to interdict activities
that represent unsafe or unsound practices or constitute violations of law,
rule, regulation, administrative orders or written agreements with a federal
bank regulator. These powers may be exercised through the issuance of
cease-and-desist orders, civil money penalties or other actions.
 
    Under the Federal Reserve Board's statement of policy with respect to bank
holding company operations, a bank holding company is required to serve as a
source of financial strength to its subsidiary depository institutions and to
commit all available resources to support such institutions in circumstances
where it might not do so absent such policy. Although this "source of strength"
policy has been challenged in litigation, the Federal Reserve Board continues to
take the position that it has authority to enforce it. For a discussion of
circumstances under which a bank holding company may be required to guarantee
the capital levels or performance of its subsidiary banks, SEE CAPITAL ADEQUACY,
below. The Federal Reserve also has the authority to terminate any activity of a
bank holding company that constitutes a serious risk to the financial soundness
or stability of any subsidiary depository institution or to terminate its
control of any bank or nonbank subsidiaries.
 
    The Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994, as
amended (the "Interstate Banking Act") generally permits bank holding companies
to acquire banks in any state, and preempts all state laws restricting the
ownership by a bank holding company of banks in more than one state. The
Interstate Banking Act also permits a bank to merge with an out-of-state bank
and convert any offices into branches of the resulting bank if both states have
not opted out of interstate branching; permits a bank to acquire branches from
an out-of-state bank if the law of the state where the branches are located
permits the interstate branch acquisition; and permits banks to establish and
operate DE NOVO interstate branches whenever the host state opts-in to DE NOVO
branching. Bank holding companies and banks seeking to engage in transactions
authorized by the Interstate Banking Act must be adequately capitalized and
managed.
 
    The Banking Law authorizes interstate branching by merger or acquisition on
a reciprocal basis, and permits the acquisition of a single branch without
restriction, but does not provide for DE NOVO interstate branching.
 
    Bank holding companies and their subsidiary banks are also subject to the
provisions of the Community Reinvestment Act of 1977 ("CRA"). Under the terms of
the CRA, the Federal Reserve Board (or other appropriate bank regulatory agency)
is required, in connection with its examination of a bank, to assess such bank's
record in meeting the credit needs of the community served by that bank,
including low-and moderate-income neighborhoods. Furthermore, such assessment is
also required of any bank that has applied, among other things, to merge or
consolidate with or acquire the assets or assume the liabilities of a
federally-regulated financial institution, or to open or relocate a branch
office. In the case of a bank holding company 

                                       9



applying for approval to acquire a bank or bank holding company, the Federal 
Reserve Board will assess the record of each subsidiary bank of the applicant 
bank holding company in considering the application. The Banking Law contains 
provisions similar to the CRA which are applicable to New York-chartered 
banks.
 
                SUPERVISION AND REGULATION OF BANK SUBSIDIARIES
 
    The Registrant's banking subsidiaries are subject to supervision and
regulation, and are examined regularly, by various bank regulatory agencies: M&T
Bank by the Federal Reserve Board and the Banking Superintendent; and M&T Bank,
N.A. by the Comptroller of the Currency (the "OCC"). The Registrant and its
direct non-banking subsidiaries are affiliates, within the meaning of the
Federal Reserve Act, of the Registrant's subsidiary banks and their
subsidiaries. As a result, the Registrant's subsidiary banks and their
subsidiaries are subject to restrictions on loans or extensions of credit to,
purchases of assets from, investments in, and transactions with the Registrant
and its direct non-banking subsidiaries and on certain other transactions with
them or involving their securities.
 
    Under the "cross-guarantee" provisions of the FDI Act, insured depository
institutions under common control are required to reimburse the FDIC for any
loss suffered by either the BIF or SAIF of the FDIC as a result of the default
of a commonly controlled insured depository institution or for any assistance
provided by the FDIC to a commonly controlled insured depository institution in
danger of default. Thus, any insured depository institution subsidiary of First
Empire could incur liability to the FDIC in the event of a default of another
insured depository institution owned or controlled by First Empire. The FDIC's
claim under the cross-guarantee provisions is superior to claims of stockholders
of
the insured depository institution or its holding company and to most claims
arising out of obligations or liabilities owed to affiliates of the institution,
but is subordinate to claims of depositors, secured creditors and holders of
subordinated debt (other than affiliates) of the commonly controlled insured
depository institution. The FDIC may decline to enforce the cross-guarantee
provisions if it determines that a waiver is in the best interest of the BIF or
SAIF or both.
 
                        DIVIDENDS FROM BANK SUBSIDIARIES
 
    M&T Bank and M&T Bank, N.A. are subject, under one or more of the banking
laws, to restrictions on the amount and frequency (no more often than quarterly)
of dividend declarations. Future dividend payments to the Registrant by its
subsidiary banks will be dependent on a number of factors, including the
earnings and financial condition of each such bank, and are subject to the
limitations referred to in note 19 of Notes to Financial Statements filed
herewith in Part II, Item 8, "Financial Statements and Supplementary Data," and
to other statutory powers of bank regulatory agencies.
 
    Under FDICIA, an insured depository institution is prohibited from making
any capital distribution to its owner, including any dividend, if, after making
such distribution, the depository institution fails to meet the required minimum
level for any relevant capital measure, including the risk-based capital
adequacy and leverage standards discussed below.
 
                                       10



                                CAPITAL ADEQUACY
 
    The Federal Reserve Board, the FDIC and the OCC have adopted risk-based
capital adequacy guidelines for bank holding companies and banks under their
supervision. Under these guidelines, the so-called "Tier 1 capital" and "Total
capital" as a percentage of risk-weighted assets and certain off-balance sheet
instruments must be at least 4% and 8%, respectively.
 
    The Federal Reserve Board, the FDIC and the OCC have also imposed a leverage
standard to supplement their risk-based ratios. This leverage standard focuses
on a banking institution's ratio of Tier 1 capital to average total assets,
adjusted for goodwill and certain other items. Under these guidelines, banking
institutions that meet certain criteria, including excellent asset quality, high
liquidity, low interest rate exposure and good earnings, and that have received
the highest regulatory rating must maintain a ratio of Tier 1 capital to total
adjusted average assets of at least 3%. Institutions not meeting these criteria,
as well as institutions with supervisory, financial or operational weaknesses,
along with those experiencing or anticipating significant growth are expected to
maintain a Tier 1 capital to total adjusted average assets ratio equal to at
least 4 to 5%.
 
    As reflected in the following table, the risk-based capital ratios and
leverage ratios of the Registrant, M&T Bank and M&T Bank, N.A. as of December
31, 1997 exceeded the required capital ratios for classification as "well
capitalized," the highest classification under the regulatory capital
guidelines.

Leverage Ratio..........................................................         9.09%         7.63%         7.11%

 
    FDICIA required the federal banking agencies, including the Federal Reserve
Board and the OCC, to revise their risk-based capital standards in order to
ensure that those standards take adequate account of interest rate risk,
concentration of credit risk and the risk of nontraditional activities, as well
as reflect the actual performance and expected risk of loss on certain
multifamily housing loans.
 
    Bank regulators periodically propose amendments to the risk-based capital
guidelines and related regulatory framework. While the Company's management
studies such proposals, the timing of adoption, ultimate form and effect of such
proposed amendments on the Company's capital requirements and operations cannot
be predicted.
 
                                       11



    FDICIA requires the federal banking agencies to take "prompt corrective
action" in respect of depository institutions and their bank holding companies
that do not meet minimum capital requirements. FDICIA established five capital
tiers: "well capitalized", "adequately capitalized", "undercapitalized",
"significantly undercapitalized" and "critically undercapitalized". A depository
institution's capital tier, or that of its bank holding company, depends upon
where its capital levels are in relation to various relevant capital measures,
including a risk-based capital measure and a leverage ratio capital measure, and
certain other factors.
 
    Under the implementing regulations adopted by the federal banking agencies,
a bank holding company or bank is considered "well capitalized" if it has (i) a
total risk-based capital ratio of 10% or greater, (ii) a Tier 1 risk-based
capital ratio of 6% or greater, (iii) a leverage ratio of 5% or greater and (iv)
is not subject to any order or written directive to meet and maintain a specific
capital level for any capital measure. An "adequately capitalized" bank holding
company or bank is defined as one that has (i) a total risk-based capital ratio
of 8% or greater, (ii) a Tier 1 risk-based capital ratio of 4% or greater and
(iii) a leverage ratio of 4% or greater (or 3% or greater in the case of a bank
with a composite CAMELS rating of 1). A bank holding company or bank is
considered (A) "undercapitalized" if it has (i) a total risk-based capital ratio
of less than 8%, (ii) a Tier 1 risk-based capital ratio of less than 4% or (iii)
a leverage ratio of less than 4% (or 3% in the case of a bank with a composite
CAMELS rating of 1); (B) "significantly undercapitalized" if the bank has (i) a
total risk-based capital ratio of less than 6%, or (ii) a Tier 1 risk-based
capital ratio of less than 3% or (iii) a leverage ratio of less than 3% and
(C)"critically undercapitalized" if the bank has a ratio of tangible equity to
total assets equal to or less than 2%. The Federal Reserve Board may reclassify
a "well capitalized" bank holding company or bank as "adequately capitalized" or
subject an "adequately capitalized" or "undercapitalized" institution to the
supervisory actions applicable to the next lower capital category if it
determines that the bank holding company or bank is in an unsafe or unsound
condition or deems the bank holding company or bank to be engaged in an unsafe
or unsound practice and not to have corrected the deficiency. First Empire, M&T
Bank and M&T Bank, N.A. currently meet the definition of "well capitalized"
institutions.

    "Undercapitalized" depository institutions, among other things, are subject
to growth limitations, are prohibited, with certain exceptions, from making
capital distributions, are limited in their ability to obtain funding from a
Federal Reserve Bank and are required to submit a capital restoration plan. The
federal banking agencies may not accept a capital plan without determining,
among other things, that the plan is based on realistic assumptions and is
likely to succeed in restoring the depository institution's capital. In
addition, for a capital restoration plan to be acceptable, the depository
institution's parent holding company must guarantee that the institution will
comply with such capital restoration plan and provide appropriate assurances of
performance. If a depository institution fails to submit an acceptable plan,
including if the holding company refuses or is unable to make the guarantee
described in the previous sentence, it is treated as if it is "significantly
undercapitalized". Failure to submit or implement an acceptable capital plan
also is grounds for the appointment of a conservator or a receiver.
"Significantly undercapitalized" depository institutions may be subject to a
number of additional requirements and restrictions, including orders to sell
sufficient voting stock to become adequately capitalized, requirements to reduce
total assets and cessation of receipt of deposits from correspondent banks.
Moreover, the parent holding company of a significantly undercapitalized
depository institution may be ordered to divest itself of the institution or of
nonbank subsidiaries of the holding company. "Critically undercapitalized"
institutions, among other things, are prohibited from making any payments of
principal and interest on subordinated debt, and are subject to the appointment
of a receiver or conservator.
 
                                       12



    FDICIA directs, among other things, that each federal banking agency
prescribe standards for depository institutions and depository institution
holding companies relating to internal controls, information systems, internal
audit systems, loan documentation, credit underwriting, interest rate exposure,
asset growth, compensation, a maximum ratio of classified assets to capital,
minimum earnings sufficient to absorb losses, a minimum ratio of market value to
book value for publicly traded shares and other standards as they deem
appropriate. The Federal Reserve Board and OCC have adopted such standards.
 
    FDICIA also contains a variety of other provisions that may affect the
operations of the Company, including new reporting requirements, regulatory
standards for real estate lending, "truth in savings" provisions, limitations on
the amount of capitalized mortgage servicing rights and purchased credit card
relationships includable in Tier 1 capital, and the requirement that a
depository institution give prior notice to customers and regulatory authorities
before closing any branch. FDICIA also contains a prohibition on the acceptance
or renewal of brokered deposits by depository institutions that are not "well
capitalized" or are "adequately capitalized" and have not received a waiver from
the FDIC.
 
                       FDIC DEPOSIT INSURANCE ASSESSMENTS
 
    As institutions with deposits insured by the BIF and the SAIF, M&T Bank and
M&T Bank, N.A. are subject to FDIC deposit insurance assessments. Under current
law the regular insurance assessments to be paid by BIF-insured and SAIF-insured
institutions are specified in schedules issued by the FDIC that specify, at
semiannual intervals, target reserve ratios designed to maintain the reserve
ratios of each of those insurance funds at 1.25% of their estimated insured
deposits. The FDIC is also authorized to impose one or more special assessments.
 
    The FDIC has implemented a risk-based deposit premium assessment system
under which each depository institution is placed in one of nine assessment
categories based on the institution's capital classification under the prompt
corrective action provisions described above, and whether such institution is
considered by its supervisory agency to be financially sound or to have
supervisory concerns. The adjusted assessment rates for both BIF-insured and
SAIF-insured institutions under the current system range from .00% to .31%
depending upon the assessment category into which the insured institution is
placed. Neither of the Company's banking subsidiaries paid regular insurance
assessments to the FDIC in 1997. However, the FDIC retains the ability to
increase regular BIF and SAIF assessments and to levy special additional
assessments.

    In addition to deposit insurance fund assessments, beginning in 1997 the
FDIC assessed BIF-assessable and SAIF-assessable deposits to fund the repayment
of debt obligations of the Financing Corporation ("FICO"). FICO is a government
agency-sponsored entity that was formed to borrow the money necessary to carry
out the closing and ultimate disposition of failed thrift institutions by the
Resolution Trust Corporation. The FDIC is required to set FICO assessments for
BIF-assessable deposits at one-fifth the amount for SAIF-assessable deposits.
The current annualized rates established by the FDIC for BIF-assessable and
SAIF-assessable deposits are 1.26 basis points and 6.28 basis points,
respectively.
 
    Any significant increases in assessment rates or additional special
assessments by the FDIC could have an adverse impact on the results of
operations and capital of M&T Bank or M&T Bank, N.A.

                             GOVERNMENTAL POLICIES
 
    The earnings of the Company are significantly affected by the monetary and
fiscal policies of governmental authorities, including the Federal Reserve
Board. Among the instruments of monetary policy used by the Federal Reserve
Board to implement these objectives are open-market operations in U.S.
Government securities and Federal funds, changes in the discount rate on member
bank borrowings and changes in reserve requirements against member bank
deposits. These instruments of monetary policy are used in varying combinations
to influence the overall level of bank loans, investments and deposits, and the
interest rates charged on loans and paid for deposits. The Federal Reserve Board
frequently uses these instruments of monetary policy, especially its open-market
operations and the discount rate, to influence the level of interest rates and
to affect the strength of the economy, the level of inflation or the price of
the dollar in foreign exchange markets. The monetary policies of the Federal
Reserve Board have had a significant effect on the operating results of banking
institutions in the past and are expected to continue to do so in the future. It
is not possible to predict the nature of future changes in monetary and fiscal
policies, or the effect which they may have on the Company's business and
earnings.
 
                                  COMPETITION
 
    The Company competes in offering commercial and personal financial services
with other banking institutions and with firms in a number of other industries,
such as thrift institutions, credit unions, personal loan companies, sales
finance companies, leasing companies, securities brokers and dealers, insurance
companies and retail merchandising organizations. Furthermore, diversified
financial services companies are able to offer a combination of these services
to their customers on a nationwide basis. Compared to less extensively regulated
financial services companies, the Company's operations are significantly
impacted by state and federal regulations applicable to the banking industry.
Moreover, the provisions of the Interstate Banking Act and the Banking Law may
further ease entry into New York State by out-of-state banking institutions. As
a result, the number of banking organizations with which the Registrant's
subsidiary banks compete may grow in the future.
 
                         OTHER LEGISLATIVE INITIATIVES
 
    From time to time, various proposals are introduced in the United States
Congress and in the New York Legislature and before various bank regulatory
authorities which would alter the powers of, and restrictions on, different
types of banking organizations and which would restructure part or all of the
existing regulatory framework for banks, bank holding companies and other
financial institutions.
 
    Moreover, a number of other bills have been introduced in Congress which
would further regulate, deregulate or restructure the financial services
industry. It is not possible to predict whether these or any other proposals
will be enacted into law or, even if enacted, the effect which they may have on
the Company's business and earnings.

ITEM 2. PROPERTIES.
 
    Both First Empire and M&T Bank maintain their executive offices at One M&T
Plaza in Buffalo, New York. This twenty-one story headquarters building,
containing approximately 276,000 rentable square feet of space, is owned in fee
by M&T Bank, and was completed in 1967 at a cost of approximately $17 million.
First Empire, M&T Bank and their subsidiaries occupy approximately 73% of the
building and the remainder is leased to non-affiliated tenants. At December 31,
1997, the cost of this property, net of accumulated depreciation, was $10.2
million.
 
    In September 1992, M&T Bank acquired an additional facility in Buffalo, New
York with approximately 365,000 rentable square feet of space at a cost of
approximately $12 million. Approximately 85% of this facility, known as M&T
Center, is occupied by M&T Bank and its subsidiaries, with the remainder leased
to non-affiliated tenants. At December 31, 1997, the cost of this building,
including improvements made subsequent to acquisition and net of accumulated
depreciation, was $15.5 million.
 
    M&T Bank also owns and occupies two separate facilities in the Buffalo area
which support certain back-office and operations functions of the Company. The
total square footage of these facilities approximates 223,000 square feet and
their combined cost, net of accumulated depreciation, was $12.8 million.
 
    The cost, net of accumulated depreciation and amortization, of the Company's
premises and equipment is detailed in note 5 of Notes to Financial Statements
filed herewith in Part II, Item 8, "Financial Statements and Supplementary
Data". Of the 178 domestic banking offices of the Registrant's subsidiary banks,
53 are owned in fee and 125 are leased.
 
ITEM 3. LEGAL PROCEEDINGS.
 
    First Empire and its subsidiaries are subject in the normal course of
business to various pending and threatened legal proceedings in which claims for
monetary damages are asserted. Management, after consultation with legal
counsel, does not anticipate that the aggregate ultimate liability, if any,
arising out of litigation pending against First Empire or its subsidiaries will
be material to First Empire's consolidated financial position, but at the
present time is not in a position to determine whether such litigation will have
a material adverse effect on First Empire's consolidated results of operations
in any future reporting period.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
  OF OPERATIONS.
 
CORPORATE PROFILE AND SIGNIFICANT DEVELOPMENTS
 
    First Empire State Corporation ("First Empire") is a bank holding company
headquartered in Buffalo, New York with consolidated assets of $14.0 billion at
December 31, 1997. First Empire and its consolidated subsidiaries are
hereinafter referred to collectively as "the Company." First Empire's banking
subsidiaries are Manufacturers and Traders Trust Company ("M&T Bank") and M&T
Bank, National Association ("M&T Bank, N.A."), which are wholly owned. M&T Bank,
with total assets of $13.4 billion at December 31, 1997, is a New York-chartered
commercial bank with 178 offices throughout New York State and an office in
Nassau, The Bahamas. M&T Bank, N.A., with $703 million in assets at December 31,
1997, is a national bank with an office in Oakfield, New York.
 
    M&T Bank's subsidiaries include M&T Mortgage Corporation, a residential
mortgage banking company; M&T Securities, Inc., a broker/dealer; M&T Real
Estate, Inc., a commercial mortgage lender; M&T Financial Corporation, a
commercial leasing company; M&T Capital Corporation, a venture capital company;
M&T Credit Corporation, a consumer credit company; and Highland Lease
Corporation, a consumer leasing company.
 
    In October 1997, First Empire entered into a definitive agreement with
ONBANCorp, Inc. ("ONBANCorp"), a bank holding company headquartered in Syracuse,
New York, for a merger between the two companies. ONBANCorp operates two
wholly-owned banking subsidiaries, OnBank & Trust Co., which has 59 offices in
upstate New York and Franklin First Savings Bank in Wilkes-Barre, Pennsylvania
which has 19 offices in Northeastern Pennsylvania. Upon consummation of the
merger, the banking subsidiaries of ONBANCorp will be merged into M&T Bank. At
December 31, 1997, ONBANCorp had approximately $5.3 billion of assets. Under the
terms of the merger agreement, stockholders of ONBANCorp will have the option to
receive .161 of a share of First Empire common stock (and cash in lieu of any
fractional share) or $69.50 in cash in exchange for each share of ONBANCorp
common stock. The merger agreement provides that a minimum of 60% and a maximum
of 70% of the total number of shares of ONBANCorp common stock issued and
outstanding immediately prior to the merger must be exchanged for shares of
First Empire common stock. In the event that ONBANCorp stockholders as a whole
elect to receive stock consideration with respect to fewer than 60% or more than
70% of the total number of outstanding shares of ONBANCorp common stock, the
selection by ONBANCorp common stockholders of the method of payment is subject
to allocation and proration to ensure that the number of shares of ONBANCorp
common stock that are converted into shares of First Empire common stock will be
60% or 70%, as the case may be, of the total number of shares of ONBANCorp
common stock issued and outstanding immediately prior to the merger. At 


 
                                       22


December 31, 1997 ONBANCorp had 12,721,689 shares of common stock issued and 
outstanding. The merger, which will be accounted for as a purchase, is 
subject to the approval of stockholders of both companies and is expected to 
be completed on or about April 1, 1998.

    In January and June 1997, First Empire completed separate offerings of trust
preferred securities raising a total of $250 million that qualifies as Tier 1 or
core capital under the Federal Reserve Board's risk-based capital guidelines.
The trust preferred securities are classified as long-term borrowings and
accumulated distributions on the securities are included in interest expense.
 
    On May 24, 1997, The East New York Saving Bank ("East New York"), the former
savings bank subsidiary of First Empire, was merged with and into M&T Bank. East
New York's branch offices and business activities now operate as the New York
City Division of M&T Bank.
 
OVERVIEW
 
    The Company's net income in 1997 was $176.2 million, representing diluted
earnings per common share of $25.26, increases of 17% and 20%, respectively,
from $151.1 million or diluted earnings per common share of $21.08 in 1996.
Basic earnings per common share rose 18% to $26.60 in 1997 from $22.54 in 1996.
In 1995, net income was $131.0 million while diluted and basic earnings per
common share were $17.98 and $19.61, respectively. The 1995 results include $4.5
million of gains from sales of bank investment securities. The impact from sales
of bank investment securities in 1997 and 1996 was negligible. Excluding the
after-tax impact of gains from sales of bank investment securities, net income
for 1995 was $128.4 million, representing diluted and basic earnings per share
of $17.62 and $19.21, respectively. All earnings per share amounts reflect the
implementation of Statement of Financial Accounting Standards ("SFAS") No. 128,
"Earnings Per Share." SFAS No. 128 establishes new standards for computing and
presenting earnings per share and is effective for financial statements for both
interim and annual periods ending after December 15, 1997. SFAS No. 128 requires
that all prior period earnings per share data be restated to conform with the
provisions of the statement.
 
    Net income represented a return on average assets in 1997 of 1.32%, compared
with 1.21% in 1996 and 1.14% in 1995. The return on average common stockholders'
equity was 18.49% in 1997, 17.60% in 1996 and 17.16% in 1995. Excluding the
effects of the 1995 securities gains, the return on average assets in 1995 was
1.12% and the return on average common stockholders' equity was 16.81%.
 
    Resulting largely from growth in average loans outstanding,
taxable-equivalent net interest income increased 5% in 1997 to $563 million from
$536 million in 1996. Average loans totaled $11.0 billion in 1997, up 8% from
$10.1 billion in 1996. Similarly, average earning assets increased 7%, to $12.8
billion in 1997 from $12.0 billion in 1996. A 9% increase in average earning
assets, primarily loans, in 1996 was also the most significant factor for the
rise in that year's net interest income from $491 million in 1995. Average loans
and average earning assets in 1995 were $8.9 billion and $11.1 billion,
respectively. Improvement in 1997's net interest income resulting from asset
growth was partially offset by a reduction of the Company's net interest margin,
or taxable-equivalent net interest income expressed as a percentage of average
earning assets. Net interest margin in 1997 was 4.38%, compared with 4.45% in
1996 and 4.43% in 1995.
 
    The provision for possible credit losses was $46.0 million in 1997, compared
with $43.3 million in 1996 and $40.4 million in 1995. Net charge-offs in 1997
were $41.8 million, compared with $35.2 million in 1996 and $21.3 million in
1995. The increase in net charge-offs from prior years 


                                       23


reflects higher levels of net consumer loan charge-offs which totaled $35.8 
million in 1997, $28.5 million in 1996 and $11.3 million in 1995.
 
    Noninterest income for 1997 totaled $193 million, 13% above the $170 million
in 1996 and 33% above the $145 million in 1995 (excluding gains from sales of
bank investment securities). Higher revenues associated with mortgage banking,
trust activities, sales of mutual funds and annuities, and prior expansion of
the Company's credit card business contributed to the growth of noninterest
income. Noninterest expense was $422 million in 1997, up 3% from $409 million in
1996 and 13% from $374 million in 1995. Expenses associated with expansion of
businesses providing mortgage banking services, indirect automobile loans,
credit cards and the sale of mutual funds and annuities contributed to the rise
in noninterest expense since 1995.

NET INTEREST INCOME/LENDING AND FUNDING ACTIVITIES
 
    Taxable-equivalent net interest income rose 5% to $563 million in 1997 from
$536 million in 1996, largely the result of growth in average earning assets,
which increased $794 million or 7% to $12.8 billion in 1997 from $12.0 billion
in 1996. Taxable-equivalent net interest income and average earning assets in
1995 were $491 million and $11.1 billion, respectively. The growth in average
earning assets in 1997 and 1996 was attributable to increases in average loans
outstanding. Average loans totaled $11.0 billion in 1997, up 8% from $10.1
billion in 1996. Average loans in 1996 were increased 14% from $8.9 billion in
1995. The accompanying table 4 summarizes average loans and leases outstanding
in 1997 and percentage changes in the major components of the loan and lease
portfolio over the past two years.
 
    Loans secured by real estate, excluding $644 million of outstanding home
equity loans and lines of credit which are classified as consumer loans,
represented approximately 58% of the loan and lease portfolio during 1997,
unchanged from 1996, but down from 60% in 1995. At December 31, 1997, the
Company held approximately $4.4 billion of commercial real estate loans and $2.5
billion of consumer real estate loans, compared with $4.0 billion and $2.2
billion, respectively, at December 31, 1996.
 
    Commercial real estate loans originated by the Company are predominately
secured by properties in the New York City metropolitan area, including areas in
neighboring states generally considered to be within commuting distance of New
York City, and Western New York, which includes Buffalo, Niagara Falls,
Rochester and surrounding areas. Commercial real estate loans are also
originated in the Hudson Valley and Southern Tier regions of New York State.
Most commercial real estate loans originated by the Company are fixed-rate
instruments with monthly payments and a balloon payment of the remaining
principal at maturity, usually five years after loan origination. For borrowers
in good standing, the customer may extend the terms of the loan agreement for an
additional five years at the then-current market rate of interest. The
accompanying table 5 presents commercial real estate loans at December 31, 1997
by geographic area, type of collateral and size of the loans outstanding. Of the
$2.4 billion of commercial real estate loans in the New York City metropolitan
area, approximately 62% were secured by multi-family residential properties, 19%
by retail space and 7% by office space. The Company's experience has been that
office space and retail properties tend to demonstrate more volatile
fluctuations in value through economic cycles and changing economic conditions
than do multi-family residential properties. Approximately 51% of the aggregate
dollar amount of New York City area loans were for $3 million or less, while
loans of more than $10 million were approximately 17% of the total. Commercial
real estate loans secured by properties elsewhere in New York State, mostly in
Western New York, tend to have a greater diversity of collateral types and
include a significant amount of lending to customers who use the mortgaged
property in their trade or business. Approximately 66% of the aggregate dollar
amount of loans in this segment of the portfolio were for $3 million or less.

                                       24


Commercial real estate loans secured by properties located outside of New 
York State and outside of areas of neighboring states considered to be part 
of the New York City metropolitan area comprised less than 5% of total 
commercial real estate loans.

    The Company normally refrains from commercial construction lending, except
when the borrower has obtained a commitment for permanent financing upon project
completion. As a result, the portfolio of commercial construction loans for
which the Company has not committed to provide permanent financing totaled only
$158 million, or 1% of total loans and leases at December 31, 1997.
 
    Real estate loans secured by one-to-four family residential properties
totaled $2.5 billion at December 31, 1997, approximately 62% of which were
secured by properties located in New York State. At December 31, 1997, $189
million of residential real estate loans were held for sale by the Company's
mortgage banking subsidiary, M&T Mortgage Corporation.
 
    Consumer loans and leases represented approximately 21% of the loan 
portfolio during 1997, compared with 22% in 1996 and 20% in 1995. Automobile 
loans and home equity loans and lines of credit represent the largest 
components of the consumer loan portfolio. At December 31, 1997, 66% of the 
automobile loan portfolio was to borrowers in New York State, while the 
remainder was primarily to borrowers in Pennsylvania. Automobile loans and 
leases are generally originated through dealers, however, all applications 
submitted by dealers are subject to the Company's normal underwriting and 
loan approval procedures. During 1997, automobile loans and leases 
represented approximately 9% of the Company's average loan portfolio, while 
no other consumer loan product represented more than 6%. During 1997, the 
Company securitized and sold $100 million of automobile loans, resulting in a 
nominal gain. Growth in average credit card balances in recent years was the 
result of direct mail marketing campaigns and co-branding initiatives. Such 
initiatives involved developing relationships with retailers and other 
enterprises and issuing co-branded credit cards that provide cardholders the 
ability to earn rebates on purchases made with the cards. The Company bears 
the cost of these rebates. As discussed later, during 1997 the Company either 
terminated or agreed to terminate several co-branded credit card programs 
that had been initiated in 1996 or late-1995. Average outstanding balances 
related to these programs were $73 million in 1997, $76 million in 1996 and 
$9 million in 1995. At December 31, 1997, 67% of outstanding credit card 
balances were with customers in New York State.
 
    The Company's portfolio of investment securities averaged $1.7 billion in
1997, $1.8 billion in 1996 and $2.0 billion in 1995. The size of the investment
securities portfolio is influenced by such factors as demand for loans, which
generally yield more than investment securities, ongoing repayments, the level
of deposits, and management of balance sheet size and resulting capital ratios.
The investment securities portfolio is largely comprised of adjustable-rate
mortgage-backed securities, collateralized mortgage obligations, and
shorter-term U.S. Treasury notes. When purchasing investment securities, the
Company considers its overall interest-rate risk profile as well as the adequacy
of expected returns relative to prepayment and other risks assumed. The Company
occasionally sells investment securities as a result of changes in interest
rates, actual or anticipated prepayments, or credit risk associated with a
particular security.
 
    The average balance of money-market assets, which are comprised of
interest-bearing deposits at banks, trading account assets, Federal funds sold
and agreements to resell securities, was $165 million in 1997, compared with
$124 million in 1996 and $186 million in 1995.
 
    Core deposits, consisting of noninterest-bearing deposits, interest-bearing
transaction accounts, savings deposits and nonbrokered domestic time deposits
under $100,000 represent the most significant source 

                                       25


of funding to the Company. Core deposits generally carry lower interest rates 
than wholesale funds of comparable maturities. The Company's New York State 
branch network is its principal source of core deposits. Certificates of 
deposit under $100,000 generated on a nationwide basis by M&T Bank, N.A. are 
also included in core deposits. In 1997, average core deposits totaled $8.3 
billion, up from $8.0 billion in 1996 and $7.4 billion in 1995. Average core 
deposits of M&T Bank, N.A., which began operations in the fourth quarter of 
1995, were $432 million in 1997, $261 million in 1996 and $3 million in 1995. 
Funding provided by core deposits totaled 65% of average earning assets in 
1997, compared with 66% in 1996 and 67% in 1995. An analysis of changes in 
the components of core deposits is presented in the accompanying table 7.
 
    The Company also obtains funding through domestic time deposits of $100,000
or more, deposits originated through the Company's offshore branch office, and
brokered certificates of deposit. Domestic time deposits over $100,000,
excluding brokered certificates of deposit, averaged $1.0 billion in 1997,
compared with $892 million in 1996 and $625 million in 1995. Offshore deposits,
comprised primarily of accounts with balances of $100,000 or more, averaged $230
million in 1997, compared with $239 million and $133 million in 1996 and 1995,
respectively. Brokered deposits averaged $1.4 billion in 1997, $1.1 billion in
1996 and $874 million in 1995, and totaled $1.4 billion at December 31, 1997.
Brokered deposits are used as an alternative to short-term borrowings to
lengthen the average maturity of interest-bearing liabilities. The
weighted-average remaining term to maturity of brokered deposits at December 31,
1997 was 2.5 years. However, certain of the deposits have provisions that allow
early redemption. Additional amounts of brokered deposits may be solicited in
the future depending on market conditions and the cost of funds available from
alternative sources at the time.

    In addition to deposits, the Company uses short-term borrowings from banks,
securities dealers, the Federal Home Loan Bank of New York ("FHLB") and others
as sources of funding. Short-term borrowings averaged $853 million in 1997, $1.1
billion in 1996 and $1.4 billion in 1995. In general, short-term borrowings have
been used to fund the Company's discretionary investments in money-market assets
and investment securities, and, if necessary, to replace deposit outflows. Also
providing funding in 1997 were two separate issuances of trust preferred
securities totaling $250 million. In January 1997, First Empire completed an
offering of trust preferred securities that raised $150 million of capital. The
30-year offering of 8.234% fixed-rate cumulative trust preferred securities was
sold through First Empire Capital Trust I. First Empire completed another
offering of trust preferred securities in June 1997 raising $100 million of
capital. This 30-year offering of 8.277% fixed-rate cumulative trust preferred
securities was sold through First Empire Capital Trust II. The preferred
securities provide investors with call protection for ten years. The trusts were
formed solely to issue the trust preferred securities and advance proceeds to
First Empire by purchasing First Empire's junior subordinated debt. The proceeds
of the trust preferred securities qualify as Tier 1 or core capital for First
Empire under the Federal Reserve Board's risk-based capital guidelines. Payments
on the junior subordinated debt of First Empire, which are in turn passed
through the trusts to the holders of the preferred securities, will be serviced
through existing liquidity and cash flow sources of First Empire. Under current
tax law, First Empire will be permitted to deduct interest payments on the
junior subordinated debt in computing taxable income. Further information
regarding the trust preferred securities is provided in note 7 of Notes to
Financial Statements. These securities, along with $175 million of subordinated
capital notes issued in prior years by M&T Bank, of which $75 million mature in
2002 and $100 million mature in 2005, are included in long-term borrowings.
Long-term borrowings averaged $373 million in 1997, $189 million in 1996 and
$146 million in 1995.
 
                                       26


    Net interest income is impacted by changes in the composition of the
Company's earning assets and interest-bearing liabilities, as described herein,
as well as changes in interest rates and spreads. Net interest spread, or the
difference between the yield on earning assets and the rate paid on
interest-bearing liabilities, was 3.70% in 1997, compared with 3.80% in 1996. A
greater proportion of loans, which typically yield more than money-market assets
and investment securities, in the composition of the earning asset portfolio
resulted in the yield on earning assets increasing slightly, to 8.34% in 1997
from 8.32% in 1996. The rate paid on interest-bearing liabilities increased 12
basis points (hundredths of one percent) to 4.64% in 1997 from 4.52% in 1996 due
to generally higher prevailing interest rates and the effect of the previously
discussed issuances of $250 million of trust preferred securities. In 1995, the
net interest spread was 3.77%, the yield on earning assets was 8.42% and the
rate paid on interest-bearing liabilities was 4.65%. A greater proportion of
loans in the composition of earning assets somewhat mitigated a general decrease
in market interest rates in 1996 compared with 1995. Largely due to the changes
in the net interest spread described herein, the Company's net interest margin
was 4.38% in 1997, compared with 4.45% in 1996 and 4.43% in 1995.
 
    Interest-free funds, consisting largely of noninterest-bearing deposits and
stockholders' equity, contributed .68% to net interest margin in 1997, compared
with .65% in 1996 and .66% in 1995. Average interest-free funds were $1.9
billion in 1997, $1.7 billion in 1996 and $1.6 billion in 1995.
 
    Future changes in market interest rates or spreads, as well as changes in 
the composition of the Company's portfolios of earning assets and 
interest-bearing liabilities that result in reductions in spreads could 
adversely impact the Company's net interest margin and net interest income. 
Management assesses the potential impact of future changes in interest rates 
and spreads by projecting net interest income under a number of different 
interest rate scenarios. As part of the management of interest rate risk, the 
Company utilizes interest rate swap agreements to modify the repricing 
characteristics of certain portions of the loan and deposit portfolios. 
Revenue and expense arising from these agreements are reflected in either the 
yields earned on loans or, as appropriate, the rates paid on interest-bearing 
deposits. The notional amount of interest rate swaps entered into for 
interest rate risk management purposes as of December 31, 1997 was 
approximately $2.7 billion. In general, under the terms of these swaps, the 
Company receives payments based on the outstanding notional amount of the 
swaps at fixed rates of interest and makes payments at variable rates. 
However, under terms of a $33 million swap, the Company pays a fixed rate of 
interest and receives a variable rate. The average notional amounts of 
interest rate swaps entered into for interest rate risk management purposes 
and the related effect on net interest income and margin are presented in the 
accompanying table 8.
 
    The Company estimates that as of December 31, 1997 it would have received
approximately $16.4 million if all interest rate swap agreements entered into
for interest rate risk management purposes had been terminated. This estimated
fair value of the interest rate swap portfolio results from the effects of
changing interest rates and should be considered in the context of the entire
balance sheet and the Company's overall interest rate risk profile. Changes in
the estimated fair value of interest rate swaps entered into for interest rate
risk management purposes are not reflected in the consolidated financial
statements. Additional information about interest rate swaps is included in note
15 of Notes to Financial Statements.
 
    The Financial Accounting Standards Board ("FASB") has issued a Proposed
Statement of Financial Accounting Standards ("Proposed Statement") that would
significantly change generally accepted accounting for interest rate swaps,
other derivative financial instruments and hedging activities. The Proposed
Statement would require that an entity recognize all derivatives (including

                                       27


interest rate swaps)as either assets or liabilities on the balance sheet and 
measure those instruments at fair value.
 
PROVISION FOR POSSIBLE CREDIT LOSSES
 
    The purpose of the provision is to replenish or build the Company's
allowance for possible credit losses to a level necessary to maintain an
adequate reserve position. Management regularly assesses the adequacy of the
allowance by performing an ongoing evaluation of the loan and lease portfolio,
including such factors as the differing economic risks associated with each loan
category, the current financial condition of specific borrowers, the economic
environment in which the borrowers operate, the level of delinquent loans and
the value of any collateral. Significant loans are individually analyzed, while
other smaller balance loans are evaluated by loan category. Based upon the
results of such review, management believes that the allowance for possible
credit losses at December 31, 1997 was adequate to absorb credit losses from
existing loans and leases.
 
    The provision for possible credit losses was $46.0 million in 1997, compared
with $43.3 million in 1996 and $40.4 million in 1995. Net charge-offs for 1997
were $41.8 million, compared with $35.2 million in 1996 and $21.3 million in
1995. As a percentage of average loans outstanding, net charge-offs were .38% in
1997, .35% in 1996 and .24% in 1995. Nonperforming loans totaled $80.7 million
or .70% of loans outstanding at December 31, 1997, compared with $97.9 million
or .91% of loans a year earlier and $93.1 million or .97% at December 31, 1995.
The allowance for possible credit losses was $274.7 million or 2.39% of net
loans and leases at the end of 1997, compared with $270.5 million or 2.52% at
December 31, 1996 and $262.3 million or 2.75% at December 31, 1995. The ratio of
the allowance to nonperforming loans was 341%, 276% and 282% at year-end 1997,
1996 and 1995, respectively.
 
    The accompanying table 10 presents a comparative allocation of the allowance
for possible credit losses for each of the past five year-ends. Amounts were 
allocated to specific loan categories based upon management's classification 
of loans under the Company's internal loan grading system and assessment of 
near-term charge-offs and losses existing in specific larger balance loans 
that are reviewed in detail by the Company's internal loan review department 
and pools of other loans that are not individually analyzed. The unallocated 
portion of the allowance is intended to provide for probable losses that are 
not otherwise identifiable resulting from (i) generally poor economic 
conditions and an unfavorable business climate in market regions served by 
the Company, (ii) portfolio concentrations regarding loan type, collateral 
type and geographic location, (iii) the effect of expansion into new markets 
and/or loan product types and, (iv) the possible use of imprecise estimates 
in determining the allocated portion of the allowance. Nevertheless, the 
allowance is general in nature and is available to absorb losses from any 
loan category. Accordingly, the amounts presented in the table do not 
necessarily indicate future losses within the individual loan categories.
 
    Several factors influence the Company's credit loss experience, including
overall economic conditions affecting businesses and consumers, in general, and,
due to the size of the Company's commercial real estate loan portfolio, real
estate valuations, in particular. Nonperforming commercial real estate loans
totaled $17.4 million, $27.1 million and $42.3 million at December 31, 1997,
1996 and 1995, respectively. At December 31, 1997, $7.0 million of nonperforming
commercial real estate loans were secured by properties located in the New York
City metropolitan area, compared with $10.3 million and $16.8 million at
December 31, 1996 and 1995, respectively. Net charge-offs of commercial real
estate loans were $.9 million in 1997, $1.5 million in 1996 and $6.6 million in
1995. Included in these totals are net charge-offs of commercial real estate
loans secured by properties in the 

                                       28


New York City metropolitan area of $1.1 million, $.6 million and $3.2 million 
in 1997, 1996 and 1995, respectively.
 
    Net charge-offs of consumer loans totaled $35.8 million in 1997, or 1.55% of
average consumer loans outstanding during the year, compared with $28.5 million
or 1.30% in 1996 and $11.3 million or .65% in 1995. Higher charge-offs of credit
card balances and indirect automobile loans were the most significant factors
contributing to the increased level of consumer loan charge-offs in 1997 and
1996 compared with 1995. Net credit card and indirect automobile loan
charge-offs in 1997 were $19.0 million and $11.2 million, respectively, compared
with $15.9 million and $9.6 million, respectively, in 1996 and $6.1 million and
$3.1 million, respectively, in 1995. The increased levels of charge-offs of
credit card and indirect automobile loans in 1997 and 1996 as compared to prior
years can, in part, be attributed to higher levels of consumer bankruptcies and,
in general, is consistent with trends reported by other financial institutions.
Nonperforming consumer loans totaled $21.9 million or .99% of outstanding
consumer loans at December 31, 1997, compared with $17.6 million or .73% at
December 31, 1996 and $13.7 million or .70% at December 31, 1995.
 
    Commercial real estate loans secured by multi-family properties in the New
York City metropolitan area were 13% of loans outstanding at December 31, 1997.
However, the Company had no concentrations of credit extended to any specific
industry that exceeded 10% of total loans at December 31, 1997. Furthermore, the
Company had no exposure to less developed countries, and only $5 million of
foreign loans in total.
 
    Assets taken in foreclosure of defaulted loans totaled $8.4 million at
December 31, 1997, compared with $8.5 million and $7.3 million at the end of
1996 and 1995, respectively.
 
OTHER INCOME
 
    Excluding the effect from sales of bank investment securities, other income
increased 14% to $193 million in 1997 from $170 million in 1996 and was 33%
higher than the $145 million earned in 1995.
 
    Mortgage banking revenues, which consist of residential mortgage loan
servicing fee income, gains from sales of residential mortgage loans and loan
servicing rights, and other residential mortgage loan-related fees, increased to
$51.5 million in 1997 from $44.5 million in 1996 and $37.1 million in 1995.
Revenues from servicing residential mortgage loans for others were $25.7 million
in 1997, $20.9 million in 1996 and $19.3 million in 1995. Gains from sales of
residential mortgage loans and loan servicing rights increased to $23.1 million
in 1997, compared with $21.6 million and $16.4 million in 1996 and 1995,
respectively. The Company originates residential mortgage loans in New York
State, as well as in Arizona, Colorado, Massachusetts, Ohio, Oregon, Utah and
Washington. Originations of residential mortgage loans were $2.1 billion in
1997, $1.9 billion in 1996 and $1.3 billion in 1995. Residential mortgage loans
serviced for others totaled $7.5 billion, $5.8 billion and $5.7 billion at
December 31, 1997, 1996 and 1995, respectively. Capitalized servicing assets
were $61.1 million at December 31, 1997, compared with $37.8 million at December
31, 1996 and $34.5 million at December 31, 1995.

    Service charges on deposit accounts increased 7% to $43.4 million in 1997
from $40.7 million in 1996, and 13% from $38.3 million in 1995. Trust income of
$30.7 million increased 11% from $27.7 million in 1996, and 20% from $25.5
million in 1995. Merchant discount and other credit card fees in 1997 totaled
$19.4 million, compared with $18.3 million in 1996 and $10.7 million in 1995.
Expansion of the Company's credit card business was the primary factor in the
improvement in 1996's fees from 1995. Due to poorer than expected results,
during 1997 the Company either terminated or agreed to 

                                       29


terminate during the first quarter of 1998 several of its co-branded credit 
card programs. These programs were initiated during 1995 and 1996. Merchant 
discount and other credit card fees earned in connection with the programs 
were approximately $7 million, $8 million and $1 million in 1997, 1996 and 
1995, respectively. Credit card balances related to these programs that 
remained outstanding at December 31, 1997 were $61 million, compared with 
$122 million a year earlier. Trading account and foreign exchange activity 
resulted in gains of $3.7 million in 1997, $2.4 million in 1996 and $2.8 
million in 1995. Other revenues from operations totaled $44.7 million in 
1997, compared with $36.8 million in 1996 and $30.7 million in 1995. Such 
amounts include revenues from sales of mutual funds and annuities of $15.3 
million, $13.0 million and $9.4 million in 1997, 1996 and 1995, respectively. 
Income earned from venture capital and other investments also contributed to 
the increase in other revenues from operations in 1997.
 
OTHER EXPENSE
 
    Other expense totaled $422 million in 1997, up from $409 million in 1996
when a $7 million charge was recognized for a special assessment to recapitalize
the Savings Association Insurance Fund of the Federal Deposit Insurance
Corporation ("FDIC"). Other expense totaled $374 million in 1995.
 
    Salaries and employee benefits expense was $220 million in 1997, an increase
of $12 million or 6% from $208 million in 1996. The increase was due largely to
higher incentive-based compensation arrangements, including stock appreciation
rights, and merit salary increases. Personnel costs in 1996 increased $20
million or 11% from $188 million in 1995. Factors contributing to such increase
were merit salary increases, costs associated with the opening of 27 supermarket
banking locations in 1996 and the second half of 1995, and the expansion of
subsidiaries providing residential mortgage banking services, indirect
automobile loans and sales of mutual funds and annuities. The number of
full-time equivalent employees was 4,781 at December 31, 1997, down from 4,832
at December 31, 1996, but up from 4,546 at December 31, 1995.
 
    Nonpersonnel expenses for 1997 totaled $202 million, little changed from
$201 million in 1996, but up 8% from $186 million in 1995. Excluding the $7
million charge in 1996 for the special assessment by the FDIC, nonpersonnel
expense increased 4% in 1997 from 1996. Higher costs associated with the
Company's mortgage banking business, including amortization of capitalized
servicing rights, contributed to the increase. The increase in nonpersonnel
expenses in 1996 from 1995 was largely caused by higher expenses associated with
the expansion of businesses providing mortgage banking services, indirect
automobile loans, credit cards and the sale of mutual funds and annuities,
partially offset by lower deposit insurance expense. Customer rebates and other
expenses based on card usage directly attributable to the terminated co-branded
credit card programs previously noted were approximately $9 million in 1997, $11
million in 1996 and $1 million in 1995.
 
INCOME TAXES
 
    The provision for income taxes in 1997 was $105.9 million, up from $97.9
million in 1996 and $90.1 million in 1995. The effective tax rates were 38% in
1997, 39% in 1996 and 41% in 1995. A reconciliation of income tax expense to the
amount computed by applying the statutory federal income tax rate to pre-tax
income is provided in note 11 of Notes to Financial Statements.

INTERNATIONAL ACTIVITIES
 
    The Company's net investment in international assets was $12 million and $55
million at December 31, 1997 and 1996, respectively. Total offshore deposits

                                       30


were $251 million and $193 million at December 31, 1997 and 1996, respectively.
 
LIQUIDITY, MARKET RISK, AND INTEREST RATE SENSITIVITY
 
    As a financial intermediary, the Company is exposed to various risks,
including liquidity and market risk. Liquidity risk arises whenever the
maturities of financial instruments included in assets and liabilities differ.
Accordingly, a critical element in managing a financial institution is ensuring
that sufficient cash flow and liquid assets are available to satisfy demands for
loans and deposit withdrawals, to fund operating expenses, and to be used for
other corporate purposes. The Company's core deposits have historically provided
a significant source of funds. Such deposits are generated from a large base of
consumer, corporate and institutional customers, which over the past several
years has become more geographically diverse as a result of acquisitions and
expansion of the Company's businesses. Nevertheless, in recent years the Company
has faced increased competition in offering services and products from a large
array of financial market participants, including banks, thrifts, mutual funds,
securities dealers and others. As a result, and consistent with banking industry
experience in general, the Company has experienced a reduction in the percentage
of earning assets funded by core deposits. Core deposits financed 64% of the
Company's earning assets at December 31, 1997, compared with 65% and 67% at
December 31, 1996 and 1995, respectively.
 
    The Company supplements funding from core deposits with various wholesale
borrowings, such as Federal funds purchased and securities sold under agreements
to repurchase, and brokered certificates of deposit. Additionally, M&T Bank has
a credit facility with the FHLB aggregating $959 million, with any borrowings
secured by loans and investment securities. Borrowings outstanding under such
credit facility totaled $22 million and $2 million at December 31, 1997 and
1996, respectively. Although informal and sometimes reciprocal, sources of
funding are available to the Company through various arrangements for unsecured
short-term borrowings from a wide group of banks and other financial
institutions. In addition to deposits and borrowings, other sources of liquidity
include maturities of money-market assets, repayments of loans and investment
securities, and cash generated from operations, such as fees collected for
services.
 
    First Empire's primary source of funds to pay for operating expenses,
dividends and treasury stock repurchases has historically been the receipt of
dividends from its banking subsidiaries, which are subject to various regulatory
limitations. As previously discussed, during 1997 First Empire issued junior
subordinated debt to two special purpose subsidiaries, which provided funding.
Additional information regarding the junior subordinated debt is included in
note 7 of Notes to Financial Statements. First Empire also maintains a $25
million line of credit with an unaffiliated commercial bank, all of which was
available for borrowing at December 31, 1997.
 
    The Company expects to have access to sufficient liquid assets to fund the
cash portion of the previously discussed ONBANCorp acquisition and, accordingly,
management does not anticipate engaging in any activities, either currently or
in the long-term, which would cause a significant strain on liquidity at either
First Empire or its subsidiary banks. Furthermore, management closely monitors
the Company's liquidity position for compliance with internal policies and
believes that available sources of liquidity are adequate to meet anticipated
funding needs.
 
    Market risk is the risk of loss from adverse changes in market prices and/or
interest rates of the Company's financial instruments. The core banking
activities of lending and deposit-taking expose the Company to interest rate
risk. As a result of interest rate risk, net interest income earned by the
Company is subject to the effects of changing interest rates. 

                                       31


The Company measures interest rate risk by calculating the variability of net 
interest income under various interest rate scenarios using projected 
balances for earning assets, interest-bearing liabilities and off-balance 
sheet financial instruments. Management's philosophy toward positioning the 
Company for interest rate movements is to attempt to limit such variability. 
The balances of both on-and off-balance sheet financial instruments used in 
the projections are based on expected growth from forecasted business 
opportunities, anticipated prepayments of mortgage-related assets and 
expected maturities of investment securities, loans and deposits. Management 
supplements the modeling technique described above with analyses of market 
values of the Company's financial instruments. As part of managing interest 
rate risk, the Company has entered into interest rate swap agreements having 
an aggregate notional amount of approximately $2.7 billion at December 31, 
1997. Information about interest rate swaps entered into for interest rate 
risk management purposes is included herein under "Net Interest 
Income/Lending and Funding Activities" and in note 15 of Notes to Financial 
Statements.
 
    The Asset-Liability Committee, which includes members of senior management,
monitors the Company's interest rate sensitivity with the aid of a computer
model which considers the impact of ongoing lending and deposit gathering
activities, as well as statistically derived interrelationships in the magnitude
and timing of the repricing of financial instruments, including the effect of
changing interest rates on expected prepayments and maturities. When deemed
prudent, management has taken action, and intends to do so in the future, to
mitigate exposure to interest rate risk through the use of on- or off-balance
sheet financial instruments. Possible actions include, but are not limited to,
changes in the pricing of loan and deposit products, modifying the composition
of earning assets and interest-bearing liabilities, and entering into or
modifying existing interest rate swap agreements.
 
    The accompanying table 13 displays the estimated impact on net interest 
income from non-trading financial instruments resulting from changes in interest
rates during the first modeling year.
 
    The calculation of the impact of changes in interest rates on net interest
income is based upon many assumptions, including prepayments of mortgage-related
assets, cash flows from derivative and other financial instruments held for
non-trading purposes, loan and deposit volumes and pricing, and deposit
maturities. The Company also assumes gradual changes in rates of 100 and 200
basis points up and down during a twelve month period. These assumptions are
inherently uncertain and, as a result, the Company cannot precisely predict the
impact of changes in interest rates on net interest income. Actual results may
differ significantly due to timing, magnitude, and frequency of interest rate
changes and changes in market conditions, as well as any actions, such as those
previously described, which management may take to counter these changes.
 
    In accordance with industry practice, the accompanying table 15 presents
cumulative totals of net assets (liabilities) repricing on a contractual basis
within the specified time frames, as adjusted for the impact of interest rate
swap agreements entered into for interest rate risk management purposes.
Management believes this measure does not appropriately depict interest rate
risk since changes in interest rates do not necessarily affect all categories of
earning assets and interest-bearing liabilities equally nor, as assumed in the
table, on the contractual maturity or repricing date. Furthermore, this static
presentation of interest rate risk fails to consider the effect of ongoing
lending and deposit gathering activities, projected changes in balance sheet
composition or any subsequent interest rate risk management activities the
Company is likely to implement.
 
    The Company engages in trading activities to meet the financial needs of
customers and to profit from perceived market opportunities. Trading activities
are conducted utilizing financial instruments that include forward 

                                       32


and futures contracts related to foreign currency exchange and 
mortgage-backed securities, U.S. Treasury and other government securities, 
and interest rate contracts such as swaps. As a result, the Company is 
exposed to foreign currency and interest rate risk resulting from its trading 
activities. However, the Company generally mitigates exposure arising from 
trading activities by entering into offsetting positions. Accordingly, the 
Company's exposure to interest rate, foreign exchange or other price risk 
related to trading activities as of December 31, 1997 was not considered 
material.

CAPITAL
 
    Total stockholders' equity at December 31, 1997 was $1.0 billion or 7.36% of
total assets, compared with $906 million or 7.00% at December 31, 1996 and $846
million or 7.08% at December 31, 1995. On a per share basis, common
stockholders' equity was $155.86 at December 31, 1997, an increase of 15% from
$135.45 at December 31, 1996 and 24% from $125.33 at December 31, 1995. The
ratio of average total stockholders' equity to average total assets was 7.16%,
6.92% and 6.81% in 1997, 1996 and 1995, respectively.
 
    Stockholders' equity at December 31, 1997 was increased by $12.0 million, or
$1.82 per common share, for the net after-tax impact of unrealized gains on
investment securities classified as available for sale, compared with a
reduction for unrealized losses of $2.5 million, or $.37 per common share, at
December 31, 1996 and $3.2 million, or $.49 per common share, at December 31,
1995. The unrealized gains at December 31, 1997 represent the amount by which
the fair value of investment securities classified as available for sale
exceeded amortized cost, net of applicable income taxes. The market valuation of
investment securities should be considered in the context of the entire balance
sheet of the Company. With the exception of investment securities classified as
available for sale, trading account assets and liabilities, and residential
mortgage loans held for sale, the carrying values of financial instruments in
the balance sheet are generally not adjusted for appreciation or depreciation in
market value resulting from changes in interest rates.
 
    Cash dividends on common stock of $21.2 million were paid in 1997, compared
with $18.6 million in 1996 and $16.2 million in 1995. The quarterly common stock
dividend rate remained at $.80 per share throughout 1997. In total, dividends
per common share increased to $3.20 in 1997 from $2.80 in 1996 and $2.50 in
1995. On March 29, 1996, all shares of First Empire's 9% convertible preferred
stock were converted by the holder of such stock into 506,930 shares of First
Empire common stock at a contractual conversion price of $78.90625 per share.
Dividends of $.9 million were paid to the preferred stockholder in 1996,
compared with $3.6 million in 1995.
 
    In February 1997, First Empire announced a plan to repurchase and hold as
treasury stock up to 303,317 shares of common stock for reissuance upon the
possible future exercise of outstanding stock options. As of December 31, 1997,
First Empire had repurchased 178,011 common shares pursuant to such plan at an
average cost of $331.78 per share. Including prior repurchase plans completed in
1997 and 1995, First Empire repurchased common shares totaling 207,073 in 1997,
336,220 in 1996 and 223,530 in 1995. The total cost of these common stock
repurchases was $67.8 million, $80.8 million and $37.4 million in 1997, 1996 and
1995, respectively.
 
    Federal regulators generally require banking institutions to maintain "core
capital" and "total capital" ratios of at least 4% and 8%, respectively, of
risk-adjusted total assets. In addition to the risk-based measures, Federal bank
regulators have also implemented a minimum "leverage" ratio guideline of 3% of
the quarterly average of total assets. Under regulatory guidelines, unrealized
gains or losses on investment securities classified as available for sale are
not recognized in determining regulatory 
 
                                       33


capital. As previously noted, core capital includes the $250 million of trust 
preferred securities issued in 1997. As of December 31, 1997 total capital 
further includes $160 million of the subordinated notes issued by M&T Bank in 
prior years. The capital ratios of the Company and its banking subsidiaries, 
M&T Bank and M&T Bank, N.A., as of December 31, 1997 are presented in note 19 
of Notes to Financial Statements.
 
    The Company has historically maintained capital ratios in excess of minimum
regulatory guidelines largely through a high rate of internal capital
generation. The rate of internal capital generation, or net income (excluding
the after-tax effects of gains or losses from sales of bank investment
securities) less dividends paid expressed as a percentage of average total
stockholders' equity, was 16.28% in 1997, 15.25% in 1996 and 13.88% in 1995.

YEAR 2000 INITIATIVES
 
    The Company is currently working to resolve the potential impact of "Year
2000" issues on the processing of date-sensitive information by the Company's
computer systems. The Year 2000 problem relates to the ability of computer
systems to be able to distinguish date data between the twentieth and
twenty-first centuries. Management anticipates that the Company's computer
systems will be Year 2000 compliant by the end of 1998 and has a planned program
to test for such compliance. The Company could also be adversely affected if its
customers rely on data processing systems that are not Year 2000 compliant prior
to the end of 1999. The Company, therefore, is taking a proactive role to work
with its data processing vendors and to provide information to its commercial
customers regarding Year 2000 issues. The costs that have been incurred by the
Company in addressing its potential Year 2000 problems have not had a material
adverse impact on the Company's financial position, results of operations or
cash flows. However, the inability of the Company or its customers to resolve
Year 2000 issues in a timely manner could result in a material financial risk.
Accordingly, the Company is devoting appropriate resources to resolve its Year
2000 issues in a timely manner and does not currently expect that doing so will
have a material adverse impact on the Company's financial position, results of
operations or cash flows in the future.
 
FOURTH QUARTER RESULTS
 
    Net income in the fourth quarter of 1997 was $46.3 million, an increase of
15% from the final quarter of 1996 when net income was $40.4 million. Diluted
earnings per common share increased 17% to $6.66 from $5.70 earned in the
year-earlier quarter. Basic earnings per share increased 16% to $7.01 in 1997's
final quarter from $6.03 in the comparable period in 1996. Taxable-equivalent
net interest income increased to $143.9 million in the fourth quarter of 1997,
up $6.0 million or 4% from $137.9 million in the corresponding 1996 quarter.
Growth in average loans outstanding was the primary factor contributing to the
improvement in net interest income. Average loans for the fourth quarter of 1997
totaled $11.3 billion, an 8% increase from the $10.5 billion average during the
fourth quarter of 1996. In total, earning assets averaged $13.2 billion in the
final quarter of 1997, up 7% from $12.3 billion in the corresponding 1996
quarter. The yield on earning assets increased to 8.34% in the final 1997
quarter from 8.31% in the year-earlier period, while the rate paid on
interest-bearing liabilities increased to 4.70% from 4.54%. The higher rate paid
on interest-bearing liabilities was due to generally higher interest rates and
the effect of the previously discussed issuances of $250 million of trust
preferred securities. The resulting net interest spread was 3.64% in the recent
quarter, compared with 3.77% in the fourth quarter of 1996. Similarly, net
interest margin decreased to 4.33% in the fourth quarter of 1997 from 4.46% in
the year-earlier quarter.

                                     34



    The provision for possible credit losses was $12.0 million in the final 1997
quarter, compared with $11.5 million in the fourth quarter of 1996. Net
charge-offs totaled $9.7 million in 1997's fourth quarter, down from $11.5
million in the year-earlier quarter. Net charge-offs as an annualized percentage
of average loans and leases were .34% in the recent quarter, down from .43% in
the corresponding 1996 quarter. Excluding the effects of sales of bank
investment securities, other income rose 10% to $53.0 million in the fourth
quarter of 1997 from $48.1 million in the year-earlier quarter. A $3.0 million
increase in revenues from mortgage banking activities was the leading factor
contributing to the rise. Other expense was $110.7 million in the fourth quarter
of 1997, an increase of 3% from $107.1 million in the fourth quarter of 1996.
 
RECENTLY ISSUED ACCOUNTING STANDARDS NOT YET ADOPTED
 
    SFAS No. 127, "Deferral of the Effective Date of Certain Provisions of FASB
Statement No. 125," was issued in December 1996 and defers until January 1,
1998, the effective date for certain provisions of SFAS No. 125 relating to
repurchase agreement, dollar roll, securities lending and similar transactions
and pledged collateral. SFAS No. 127 will be adopted by the Company in the first
quarter of 1998, as required, and is not expected to have a material impact on
the Company's results of operations.

    In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income." SFAS No. 130 establishes standards for reporting and displaying
comprehensive income and its components, and requires that all items that are
required to be recognized under accounting standards be reported in a financial
statement that is displayed with the same prominence as other financial
statements. SFAS No. 130 is effective for fiscal years beginning after December
15, 1997 and reclassification of financial statements for earlier periods
provided for comparative purposes is required. The Company will adopt the
provisions of SFAS No. 130 in the first quarter of 1998. When adopted, SFAS No.
130 is not expected to have a material impact on the Company.
 
    SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
Information," also issued in June 1997, establishes new standards for reporting
information about operating segments in annual and interim financial statements.
SFAS No. 131 also requires descriptive information about the way the operating
segments are determined, the products and services provided by the segments and
the nature of differences between reportable segment measurements and those used
for the consolidated enterprise. SFAS No. 131 is effective for years beginning
after December 15, 1997. SFAS No. 131 need not be applied to interim financial
statements in the initial year of application, but comparative information for
interim periods in the initial year of application is to be reported in the
financial statements for interim periods in the year after initial application.
The Company will apply the provisions of SFAS No. 131 in 1998, as required.
 
    In February 1998, the FASB issued SFAS No. 132, "Employers' Disclosures
about Pensions and Other Postretirement Benefits." SFAS No. 132 revises current
disclosure requirements for employers' pensions and other retiree benefits. SFAS
No. 132 is effective for fiscal years beginning after December 15, 1997.

*   Changes were calculated from unrounded amounts.
 
**  Interest income data are on a taxable-equivalent basis. The
    taxable-equivalent adjustment represents additional income taxes that would
    be due if all interest income were subject to income taxes. This adjustment
    is primarily to interest received on qualified municipal securities and
    industrial revenue financings and is based on a composite income tax rate of
    approximately 41% for 1997, 42% for 1996, 1995 and 1993, and 43% for 1994.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders of
First Empire State Corporation:
 
    We have audited the accompanying consolidated balance sheet of First Empire
State Corporation and subsidiaries as of December 31, 1997 and 1996, and the
related consolidated statements of income, cash flows and changes in
stockholders' equity for each of the three years in the period ended December
31, 1997. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits 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 provide a reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements audited by us present
fairly, in all material respects, the financial position of First Empire State
Corporation and subsidiaries at December 31, 1997 and 1996, and the results of
their operations and their cash flows for each of the three years in the period
ended December 31, 1997, in conformity with generally accepted accounting
principles.

                         NOTES TO FINANCIAL STATEMENTS
 
1. SIGNIFICANT ACCOUNTING POLICIES
 
    First Empire State Corporation ("First Empire") is a bank holding company
headquartered in Buffalo, New York. Through subsidiaries, First Empire provides
individuals, corporations and institutions with commercial and retail banking
services, including loans and deposits, trust, mortgage banking, asset
management and other financial services. Banking activities are largely focused
on consumers residing in New York State and in New York-based small and
medium-size businesses. However, certain subsidiaries conduct activities in
markets outside of New York State. The preparation of financial statements in
conformity with generally accepted accounting principles 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.
The accounting and reporting policies of First Empire State Corporation and
subsidiaries ("the Company") conform to generally accepted accounting principles
and to general practices within the banking industry. The more significant
accounting policies are as follows:
 
CONSOLIDATION
 
    The consolidated financial statements include First Empire and all of its
subsidiaries. All significant intercompany accounts and transactions have been
eliminated in consolidation. The financial statements of First Empire included
in note 20 report investments in subsidiaries under the equity method.
 
CONSOLIDATED STATEMENT OF CASH FLOWS
 
    For purposes of this statement, cash and due from banks, Federal funds sold
and agreements to resell securities are considered cash and cash equivalents.
 
TRADING ACCOUNT
 
    Financial instruments used for trading purposes are stated at fair value.
Realized gains and losses and unrealized changes in fair value are included in
trading account and foreign exchange gains in the Consolidated Statement of
Income.
 
INVESTMENT SECURITIES
 
    Investments in debt securities are classified as held to maturity and stated
at amortized cost when management has the positive intent and ability to hold
such securities to maturity. Investments in other debt securities and equity
securities having readily determinable fair values are classified as available
for sale and stated at estimated fair value. Unrealized gains or losses related
to investment securities available for sale are reflected in stockholders'
equity, net of applicable income taxes.
 
    Other securities include stock of the Federal Reserve Bank of New York and
the Federal Home Loan Bank of New York and are stated at cost.
 
    Amortization of premiums and accretion of discounts for investment
securities available for sale and held to maturity are included in interest
income. The cost basis of individual securities is written down to estimated
fair value through a charge to earnings when declines in value below

INVESTMENT SECURITIES (CONTINUED)

amortized cost are considered to be other than temporary. Realized gains and 
losses on the sales of investment securities are determined using the 
specific identification method.

LOANS

    Interest income on loans is accrued on a level yield method. Loans are
placed on nonaccrual status and previously accrued interest thereon is charged
against income when principal or interest is delinquent 90 days, unless
management determines that the loan status clearly warrants other treatment.
Loan balances are charged off when it becomes evident that such balances are not
fully collectible. Loan fees and certain direct loan origination costs are
deferred and recognized as an interest yield adjustment over the life of the
loan. Net deferred fees have been included in unearned discount as a reduction
of loans outstanding. Loans held for sale are carried at the lower of aggregate
cost or fair market value. Valuation adjustments made on these loans are
included in mortgage banking revenues.
 
    Except for consumer and residential mortgage loans that are considered
smaller balance homogenous loans and are evaluated collectively, the Company
considers a loan to be impaired when, based on current information and events,
it is probable that the Company will be unable to collect all amounts according
to the contractual terms of the loan agreement or the loan is delinquent 90
days. Impaired loans are classified as either nonaccrual or as loans
renegotiated at below market rates. Loans less than 90 days delinquent are
deemed to have a minimum delay in payment and are generally not considered
impaired. Impairment of a loan is measured based on the present value of
expected future cash flows discounted at the loan's effective interest rate, the
loan's observable market price, or the fair value of collateral if the loan is
collateral dependent. Interest received on impaired loans placed on nonaccrual
status is applied to reduce the carrying value of the loan or, if principal is
considered fully collectible, recognized as interest income.
 
ALLOWANCE FOR POSSIBLE CREDIT LOSSES
 
    The allowance for possible credit losses represents the amount which, in
management's judgment, will be adequate to absorb credit losses from existing
loans and leases. The adequacy of the allowance is determined by management's
evaluation of the loan portfolio based on such factors as the differing economic
risks associated with each loan category, the current financial condition of
specific borrowers, the economic environment in which borrowers operate, any
delinquency in payments, and the value of any collateral.
 
PREMISES AND EQUIPMENT
 
    Premises and equipment are stated at cost less accumulated depreciation.
Depreciation expense is computed principally using the straight-line method over
the estimated useful lives of the assets.

CAPITALIZED SERVICING RIGHTS
 
    Effective January 1, 1997, the Company adopted the provisions of Statement
of Financial Accounting Standards ("SFAS") No. 125, "Accounting for Transfers
and Servicing of Financial Assets and Extinguishment of Liabilities," not
deferred by SFAS No. 127, "Deferral of the Effective Date of Certain Provisions
of FASB Statement No. 125." SFAS No. 125 supersedes SFAS No. 122, "Accounting
for Mortgage Servicing Rights." As a result, the Company recognizes as separate
assets or liabilities rights to service financial instruments for others.
Retroactive application of the provisions of SFAS No. 125 to prior years is not
permitted.
 
    Servicing rights retained in a sale or securitization of financial assets 
are measured at the date of transfer by allocating the previous carrying 
amount between the assets transferred and the servicing rights based on their 
relative fair values. Servicing assets purchased or servicing liabilities 
assumed are initially measured at fair value. Capitalized servicing assets 
are included in other assets and amortized in proportion to and over the 
period of estimated net servicing income.
 
    To estimate the fair value of servicing rights, the Company considers market
prices for similar assets and the present value of expected future cash flows
associated with the servicing rights calculated using assumptions that market
participants would use in estimating future servicing income and expense. Such
assumptions include estimates of the cost of servicing loans, loan default
rates, an appropriate discount rate, and prepayment speeds. For purposes of
evaluating and measuring impairment of capitalized servicing rights, the Company
stratifies such assets based on predominant risk characteristics of underlying
financial instruments that are expected to have the most impact on projected
prepayments, cost of servicing and other factors affecting future cash flows
associated with the servicing rights. Such factors may include financial asset
or loan type, note rate and term. The amount of impairment recognized is the
amount by which the carrying value of the capitalized servicing rights for a
stratum exceeds estimated fair value. Impairment is recognized through a
valuation allowance.
 
GOODWILL
 
    The excess of the cost of acquired entities or operations over the fair
value of identifiable assets acquired less liabilities assumed is recorded as
goodwill and included in other assets. Goodwill is amortized on a straight-line
basis over periods which may vary depending on the circumstances of each
acquisition. For acquisitions completed through December 31, 1997, such
amortization periods have generally not exceeded five years. The Company
periodically assesses whether events or changes in circumstances indicate that
the carrying amount of goodwill may be impaired. Impairment is measured using
estimates of future cash flows or earnings potential of the operations acquired.
The aggregate amount of goodwill totaled $17,288,000 and $18,923,000 at December
31, 1997 and 1996, respectively.
 
STOCK-BASED COMPENSATION
 
    Compensation expense is not recognized for stock option awards to employees
under the Company's stock option plan since the exercise price of options is
equal to the market price of the underlying stock at the date of grant.
Compensation expense for stock appreciation rights issued separately from

STOCK-BASED COMPENSATION (CONTINUED)

stock options is recognized based upon changes in the quoted market value of 
First Empire's common stock. The pro forma effects of stock-based 
compensation arrangements are based on the estimated grant date fair value of 
stock options that are expected to vest calculated pursuant to the provisions 
of SFAS No. 123, "Accounting for Stock-Based Compensation." Pro forma 
compensation expense, net of applicable income tax effect, is recognized over 
the vesting period, which is generally four years.
 
INCOME TAXES
 
    Deferred tax assets and liabilities are recognized for the future tax
effects attributable to differences between the financial statement value of
existing assets and liabilities and their respective tax bases and
carryforwards. Deferred tax assets and liabilities are measured using enacted
tax rates and laws. Investment tax credits related to leveraged leasing property
are amortized into income tax expense over the life of the lease agreement.
 

FINANCIAL FUTURES
 
    Outstanding financial futures contracts represent future commitments and are
not included in the Consolidated Balance Sheet. Futures contracts used in
trading activities are marked to market and the resulting gains or losses are
recognized in trading account and foreign exchange gains. On occasion the
Company uses interest rate futures contracts as part of its management of
interest rate risk. Gains and losses on futures contracts designated as hedges
are amortized as an adjustment to interest income or expense over the life of
the item hedged.
 
INTEREST RATE SWAP AGREEMENTS
 
    For interest rate swap agreements used to manage interest rate risk arising
from financial assets and liabilities, amounts receivable or payable are
recognized as accrued under the terms of the agreement and the net interest
differential, including any amortization of premiums paid or accretion of
discounts received, is recorded as an adjustment to interest income or expense
of the related asset or liability. To qualify for such accounting treatment, an
interest rate swap must (i) be designated as having been entered into for
interest rate risk management purposes and linked to a specific financial
instrument or pool of similar financial instruments in the Company's
Consolidated Balance Sheet and (ii) have interest rate and repricing
characteristics that have a sufficient degree of correlation with the
corresponding characteristics of the designated on-balance sheet financial
instrument. Gains or losses resulting from early termination of interest rate
swap agreements used to manage interest rate risk are amortized over the shorter
of the remaining term or estimated life of the agreement or the on-balance sheet
financial instrument to which the swap had been linked. Agreements and
commitments that do not satisfy the requirements noted above, including those
entered into for trading purposes, are marked to market with resulting gains or
losses recorded in trading account and foreign exchange gains.

EARNINGS PER COMMON SHARE
 
    The Company adopted SFAS No. 128, "Earnings Per Share," in the fourth
quarter of 1997. SFAS No. 128 establishes new standards for computing and
presenting earnings per share and is effective for financial statements for both
interim and annual periods ending after December 15, 1997. SFAS No. 128 requires
that all prior period earnings per share data be restated to conform with the
provisions of the statement. SFAS No. 128 eliminates primary earnings per share
and fully diluted earnings per share and requires the presentation of basic and
diluted earnings per share.
 
    Basic earnings per share excludes dilution and is computed by dividing
income available to common stockholders by the weighted-average number of common
shares outstanding for the period. Diluted earnings per share reflects the
potential dilution that could occur if securities or other contracts to issue
common stock were exercised or converted into common stock or resulted in the
issuance of common stock that then shared in earnings. Proceeds assumed to have
been received on such exercise or conversion are assumed to be used to purchase
shares of First Empire common stock at the average market price during the
period, as required by the "treasury stock method" of accounting.
 
TREASURY STOCK
 
    Repurchases of shares of First Empire common stock are recorded at cost as a
reduction of stockholders' equity. Reissuances of shares of treasury stock are
recorded at average cost.

    One-to-four family residential mortgage loans held for sale were $189.4
million at December 31, 1997 and $193.6 million at December 31, 1996.
One-to-four family residential mortgage loans serviced for others totaled
approximately $7.5 billion and $5.8 billion at December 31, 1997 and 1996,
respectively. As of December 31, 1997, approximately $13.0 million of
one-to-four family residential mortgage loans serviced for others have been sold
with recourse. The total credit loss exposure resulting from loans sold with
recourse was considered negligible.
 
    Included in the preceding table are nonperforming loans (loans on which 
interest was not being accrued, or which were ninety days or more past due or 
had been renegotiated at below-market interest rates) of $80,650,000 at 
December 31, 1997 and $97,884,000 at December 31, 1996. If nonaccrual and 
renegotiated loans had been accruing interest at their originally contracted 
terms, interest income on these loans would have amounted to $7,264,000 in 
1997 and $6,854,000 in 1996. The actual amount included in interest income

    As a result of impairment of certain strata of capitalized servicing 
assets, additions to the valuation allowance totaling $500,000 and $1,100,000 
were recorded during 1997 and 1996, respectively. During 1997, the valuation 
allowance was reduced by $802,000 to reflect the write-down of the recorded 
value of certain capitalized servicing assets related to loans that had been 
repaid by borrowers. There were no additions or reductions to the valuation 
allowance recorded during 1996. SFAS No. 125 requires that for each servicing 
contract in existence before January 1, 1997 previously recognized servicing 
rights and excess servicing receivables that do not exceed contractually 
specified servicing fees be combined. The carrying value of such excess 
servicing receivables at January 1, 1997 was $4,074,000. The estimated fair 
value of capitalized servicing rights was approximately $84 million at 
December 31, 1997 and $59 million at December 31, 1996. Such amounts were 
estimated using discounted cash flows that reflect current prepayment and 
discount rate assumptions as of each year-end.

    The subordinated notes of M&T Bank are unsecured and are subordinate to the
claims of depositors and other creditors of M&T Bank. Long-term borrowings from
the Federal Home Loan Bank of New York had fixed rates of interest ranging from
7.72% to 8.45% at December 31, 1997 and 1996. Such advances mature at various
dates through 2006 and are secured by residential mortgage loans.
 
    In January 1997, First Empire Capital Trust I ("Trust I"), a Delaware
business trust organized by the Company on January 17, 1997, issued $150 million
of 8.234% preferred capital securities. In June 1997, First Empire Capital Trust
II ("Trust II" and, together with Trust I, the "Trusts"), a Delaware business
trust organized by the Company on May 30, 1997, issued $100 million of 8.277%
preferred capital securities.

    Other than the following payment terms (and the redemption terms 
described below), the preferred capital securities issued by the Trusts 
("Capital Securities") are identical in all material respects:
 


           DISTRIBUTION

 Trust I         8.234%     February 1 and August 1
Trust II         8.277%      June 1 and December 1

 
    The common securities of each Trust ("Common Securities") are wholly owned
by First Empire, and such securities are the only class of each Trust's
securities possessing general voting powers. The Capital Securities represent
preferred undivided interests in the assets of the corresponding Trust and are
classified in the Company's consolidated balance sheet as long-term borrowings,
with accumulated distributions on such securities included in interest expense.
Under the Federal Reserve Board's current risk-based capital guidelines, the
Capital Securities are includable in First Empire's Tier 1 capital.
 
    The proceeds from the issuances of the Capital Securities and Common 
Securities were used by the Trusts to purchase the following amounts of 
junior subordinated deferrable interest debentures ("Junior Subordinated 
Debentures") issued by First Empire:

Trust I    $  150 million  $  4.64 million  $154.64 million aggregate liquidation amount of 8.234% Junior
                                            Subordinated Debentures due February 1, 2027.
 
Trust II   $  100 million  $  3.09 million  $103.09 million aggregate liquidation amount of 8.277% Junior
                                            Subordinated Debentures due June 1, 2027.

 
    The Junior Subordinated Debentures represent the sole assets of each Trust
and payments under the Junior Subordinated Debentures are the sole source of
cash flow for each Trust.
 
    Holders of the Capital Securities receive preferential cumulative cash
distributions semi-annually on each distribution date at the stated distribution
rate unless First Empire exercises its right to extend the payment of interest
on the Junior Subordinated Debentures for up to ten semi-annual periods, in
which case payment of distributions on the Capital Securities will be deferred
for a comparable period. During an extended interest period, First Empire may
not pay dividends or distributions on, or repurchase, redeem or acquire any
shares of its capital stock. The agreements governing the Capital Securities, in
the aggregate, provide a full, irrevocable and unconditional guarantee by First
Empire of the payment of distributions on, the redemption of, and any
liquidation distribution with respect to the Capital Securities. The obligations
of First Empire under

such guarantee and the Capital Securities are subordinate and junior in right 
of payment to all senior indebtedness of First Empire.
 
    The Capital Securities are mandatorily redeemable in whole, but not in 
part, upon repayment at the stated maturity dates of the Junior Subordinated 
Debentures or the earlier redemption of the Junior Subordinated Debentures in 
whole upon the occurrence of one or more events ("Events") set forth in the 
indentures relating to the Capital Securities, and in whole or in part at any 
time after the stated optional redemption dates (February 1, 2007 in the case 
of Trust I and June 1, 2007 in the case of Trust II) contemporaneously with 
First Empire's optional redemption of the related Junior Subordinated 
Debentures in whole or in part. The Junior Subordinated Debentures are 
redeemable prior to their stated maturity dates at First Empire's option (i) 
on or after the stated optional redemption dates, in whole at any time or in 
part from time to time, or (ii) in whole, but not in part, at any time within 
90 days following the occurrence and during the continuation of one or more 
of the Events, in each case subject to possible regulatory approval. The 
redemption price of the Capital Securities upon early redemption will be 
expressed as a percentage of the liquidation amount plus accumulated but 
unpaid distributions. In the case of Trust I, such percentage adjusts 
annually and ranges from 104.117% at February 1, 2007 to 100.412% for the 
annual period ending January 31, 2017, after which the percentage is 100% 
subject to a make-whole amount if the early redemption occurs prior to 
February 1, 2007. In the case of Trust II, such percentage adjusts annually 
and ranges from 104.139% at June 1, 2007 to 100.414% for the annual period 
ending May 31, 2017, after which the percentage is 100%, subject to a 
make-whole amount if the early redemption occurs prior to June 1, 2007.
 
    Long-term borrowings at December 31, 1997 mature as follows:

8. PREFERRED STOCK
 
    On March 29, 1996, the holder of all of the then outstanding shares of First
Empire's 9% convertible preferred stock converted such shares into 506,930
shares of First Empire common stock at a contractual conversion price of
$78.90625 per common share. Dividends paid on the 40,000 shares of preferred
stock, which had been issued on March 15, 1991 for $40 million, were deducted
from net income in calculating basic earnings per share. Calculations of diluted
earnings per common share for periods prior to the conversion reflect the
assumption that the preferred stock had been converted to 506,930 shares of
common stock at issuance and that no preferred stock dividends were paid.

9. STOCK-BASED COMPENSATION PLANS
 
STOCK OPTION PLAN
 
    The stock option plan allows the grant of stock options and stock 
appreciation rights (either in tandem with options or independently) at 
prices which may not be less than the fair market value of the common stock 
on the date of grant. Awards granted under the stock option plan generally 
vest over four years and are exercisable over terms not exceeding ten years 
and one day. When exercisable, the stock appreciation rights issued in tandem 
with stock options entitle grantees to receive cash, stock or a combination 
equal to the amount of stock appreciation between the dates of grant and 
exercise. Stock appreciation rights issued independently of stock options 
contain similar terms as the stock options, although upon exercise the holder 
is only entitled to receive cash instead of purchasing shares of First 
Empire's common stock. Of the stock options outstanding at December 31, 1997, 
751,606 were granted with limited stock appreciation rights attached thereto.

    The Company used a binomial option pricing model to estimate the grant date
present value of stock options granted in 1997, 1996 and 1995. The estimated
value per option was $79.26 in 1997, $49.75 in 1996 and $44.36 in 1995. The
values were calculated using the following assumptions: an option term of 6.5
years (representing the estimated period between grant date and exercise date
based on historical data since inception of the plan), a risk-free interest rate
of 6.37% in 1997, 5.48% in 1996 and 7.70% in 1995 (representing the yield on a
U.S. Treasury security with a remaining term equal to the expected option term),
expected volatility of 14% in 1997, 15% in 1996 and 16% in 1995, and estimated
dividend yields of 0.97% in 1997, 1.28% in 1996 and 1.70% in 1995 (representing
the approximate annualized cash dividend rate paid with respect to a share of
common stock at or near the grant date). The Company also deducted 10% to
reflect an estimate of the probability of forfeiture prior to vesting. The
estimated forfeiture rate was based on historical data since inception of the
stock option plan.
 
    The Company applies Accounting Principles Board Opinion No. 25, "Accounting
for Stock Issued to Employees," and related interpretations in accounting for
the stock option plan. Accordingly, no compensation expense was recognized in
1997, 1996 and 1995 for stock option awards since the exercise price of stock
options granted under the stock option plan was not less than the fair market
value of the common stock at date of grant. Compensation expense recognized for
cash-only stock appreciation rights was $8,510,000 in 1997, $3,974,000 in 1996
and $6,002,000 in 1995. Had compensation expense for stock option awards granted
in 1997, 1996 and 1995 been determined consistent with SFAS No. 123, net income
and earnings per share would be reduced to the pro forma amounts indicated
below:

9. STOCK-BASED COMPENSATION PLANS (CONTINUED)

STOCK OPTION PLAN (CONTINUED)
 
    The pro forma effects presented above are in accordance with the
requirements of SFAS No. 123, however, such effects are not representative of
the effects to be reported in future years due to the fact that options vest
over several years and additional awards generally are made each year.
 
DEFERRED BONUS PLAN
 
    In connection with the deferred bonus plan, the Company provides a deferred
bonus plan to eligible employees which allows such employees to elect to defer
all or a portion of their current annual incentive compensation awards and
allocate such awards to several investment options, including First Empire
common stock. Participants may elect the timing of distributions from the plan.
Such distributions are payable in cash, with the exception of balances allocated
to First Empire common stock which effective January 1, 1998, will be
distributable in the form of First Empire common stock. As of January 1, 1998,
$3,281,000 was distributable in the form of 7,056 shares of First Empire common
stock. In connection with the deferred bonus plan, 15,000 shares of First Empire
common stock are authorized for issuance.
 
DIRECTORS' STOCK PLAN
 
    Effective January 1, 1998, the Company initiated a compensation plan for
non-employee directors which provides that annual compensation payable to such
directors shall be paid fifty percent in cash and fifty percent in shares of
First Empire common stock. In connection with the directors' stock plan, 5,000
shares of First Empire common stock are authorized for issuance.
 
10. PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS
 
    The Company has a noncontributory defined benefit pension plan covering
substantially all full-time employees. Pension benefits accrue to participants
based on their level of compensation and number of years of service. With
respect to employees added as a result of acquisitions, service with the
acquired entities has generally been counted in the pension formula for vesting,
but not for benefit accrual purposes. The Company contributes to the pension
plan amounts sufficient to meet Internal Revenue Code funding standards.
 
    Net periodic pension cost consisted of the following:

    The Company files a consolidated federal income tax return reflecting 
taxable income earned by all subsidiaries. Prior to 1996, applicable federal 
tax law allowed First Empire the option of deducting as bad debt expense for 
tax purposes, under the reserve method, 8% of taxable income resulting from 
the banking operations of a subsidiary. Effective January 1, 1996, the 
reserve method is no longer available and deductions for bad debts for 
federal income tax purposes are now limited to actual losses. Recapture of 
the bad debt reserve established by prior application of the reserve method 
will result in taxable income if M&T Bank fails to maintain bank status as 
defined in the Internal Revenue Code or charges are made to the reserve for 
other than bad debt losses. At December 31, 1997 the bad debt reserve 
resulting from application of the reserve method for which no federal income 
taxes have been provided was $46,717,000. No actions are planned which would 
cause this reserve to become wholly or partially taxable.
 
    The portion of income taxes attributable to gains or losses on sales of bank
investment securities was a benefit of $114,000 in 1997 and an expense of
$1,872,000 in 1995. The effect on income taxes from sales of bank investment
securities was insignificant in 1996. No alternative minimum tax expense was
recognized in 1997, 1996 or 1995.
 
    Total income taxes differed from the amount computed by applying the
statutory federal income tax rate to pre-tax income as follows:
 


                                                                   1997       1996       1995

    The Company believes that it is more likely than not that the net deferred
tax asset will be realized through taxable earnings or alternative tax
strategies.
 
    The income tax credits shown in the Statement of Income of First Empire in
note 20 arise principally from operating losses before dividends from
subsidiaries.

15. DERIVATIVE FINANCIAL INSTRUMENTS
 
    As part of managing interest rate risk, the Company has entered into several
interest rate swap agreements. The swaps modify the repricing characteristics of
certain portions of the Company's loan and deposit portfolios. Under terms of
most of the agreements the Company receives a fixed rate of interest and pays a
variable rate based on London Inter-Bank Offered Rates ("LIBOR"). Interest rate
swap agreements are generally entered into with counterparties that meet
established credit standards and most contain collateral provisions protecting
the at-risk party. The Company considers the credit risk inherent in these
contracts to be negligible. Information about interest rate swaps entered into
for interest rate risk management purposes summarized by type of financial
instrument the swaps were intended to modify follows:

    The estimated fair value of interest rate swap agreements represents the
amount the Company would have expected to receive (pay) to terminate such
contracts. Since these swaps have been entered into for interest rate risk
management purposes, the estimated market appreciation or depreciation should be
considered in the context of the entire balance sheet of the Company. The
estimated fair value of interest rate swaps entered into for interest rate risk
management purposes is not recognized in the consolidated financial statements.
 
    The notional amount of the amortizing swap linked to fixed rate loans
declines by the amount of scheduled principal payments of the loans. The
notional amounts of other amortizing swaps may, following an initial lock-out
period, vary depending on the level of interest rates or the repayment behavior
of mortgage-backed securities to which individual swaps are indexed. The
notional amount of a non-amortizing swap does not change during the term of an
agreement.
 
    At December 31, 1997 the notional amount of interest rate swaps outstanding
mature as follows:

    The net effect of interest rate swaps was to increase net interest income by
$14,089,000 in 1997, $15,454,000 in 1996 and $884,000 in 1995. The average
notional amount of interest rate swaps impacting net interest income which were
entered into for interest rate risk management purposes were $2,691,638,000 in
1997, $2,410,547,000 in 1996 and $2,536,329,000 in 1995.
 
    During 1995 and 1994, the Company restructured several interest rate swap
agreements with notional amounts of $260 million and $500 million, respectively,
from amortizing to non-amortizing. The purpose of the restructurings was to
enhance the effectiveness of the swaps in managing the Company's exposure to
changing interest rates in future years. Losses resulting from the early
termination of the amortizing swaps and equal amounts of purchase discount
received on the restructured non-amortizing swaps were recognized as a result of
these transactions and included in the carrying amount of loans which the swaps
modified. The deferred losses and purchase discounts totaled $9.5 million and
$15.8 million, respectively, at December 31, 1997 and $20.8 million and $25.4
million, respectively, at December 31, 1996. The deferred losses are being
amortized and the purchase discounts accreted to interest income over the
remaining terms of the original swaps and restructured swaps, respectively. Such
amortization and accretion were $11.3 million and $9.6 million, respectively, in
1997, $12.1 million and $9.8 million, respectively, in 1996 and $11.1 million
and $8.8 million, respectively, in 1995.

16. DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    SFAS No. 107, "Disclosures about Fair Value of Financial Instruments,"
requires disclosure of the estimated "fair value" of financial instruments.
"Fair value" is generally defined as the price a willing buyer and a willing
seller would exchange for a financial instrument in other than a distressed sale
situation. Disclosures related to fair value presented herein are as of December
31, 1997 and 1996.
 
    With the exception of marketable securities, certain off-balance sheet 
financial instruments and one-to-four family residential mortgage loans 
originated for sale, the Company's financial instruments are not readily 
marketable and market prices do not exist. The Company, in attempting to 
comply with the provisions of SFAS No. 107, has not attempted to market its 
financial instruments to potential buyers, if any exist. Since negotiated 
prices in illiquid markets depend greatly upon the then present motivations 
of the buyer and seller, it is reasonable to assume that actual sales prices 
could vary widely from any estimate of fair value made without the benefit of 
negotiations. Additionally, changes in market interest rates can dramatically 
impact the value of financial instruments in a short period of time.
 
    The estimated fair value of investments in readily marketable debt and
equity securities were based on quoted market prices at the respective year-end.
In arriving at estimated fair value of other financial instruments, the Company
generally used calculations based upon discounted cash flows of the related
financial instruments. In general, discount rates used for loan products were
based on the Company's pricing at the respective year-end. A

    The allowance for possible credit losses represents the Company's assessment
of the overall level of credit risk inherent in the loan and lease portfolio and
totaled $274,656,000 and $270,466,000 at December 31, 1997 and 1996,
respectively.
 
    As described in note 17, in the normal course of business, various
commitments and contingent liabilities are outstanding, such as loan
commitments, credit guarantees and letters of credit. The Company's pricing of
such financial instruments is based largely on credit quality and relationship,
probability of funding and other requirements. Commitments generally have fixed
expiration dates and contain termination and other clauses which provide for
relief from funding in the event of significant deterioration in the credit
quality of the customer. The rates and terms of the Company's loan commitments,
credit guarantees and letters of credit are competitive with other financial
institutions operating in markets served by the Company. The Company believes
that the carrying amounts are reasonable estimates of the fair value of these
financial instruments. Such carrying amounts, comprised principally of
unamortized fee income, are included in other liabilities and totaled $4,911,000
and $3,619,000 at December 31, 1997 and 1996, respectively.

    SFAS No. 107 requires that the estimated fair value ascribed to
noninterest-bearing deposits, savings deposits and NOW accounts be established
at carrying value because of the customers' ability to withdraw funds

    The Company believes that deposit accounts have a value greater than that
prescribed by SFAS No. 107. The Company feels, however, that the value
associated with these deposits is greatly influenced by characteristics of the
buyer, such as the ability to reduce the costs of servicing the deposits, and
the expected deposit attrition which is customary in acquisitions. Accordingly,
estimating the fair value of deposits with any degree of certainty is not
practical.
 
    As more fully described in note 15, the Company had entered into interest
rate swap agreements for purposes of managing the Company's exposure to changing
interest rates. The estimated fair value of interest rate swap agreements
represents the amount the Company would have expected to receive or pay to
terminate such swaps. The following table includes information about the
estimated fair value of interest rate swaps entered into for interest rate risk
management purposes:

    As described in note 15, the Company also uses certain derivative financial
instruments as part of its trading activities. Interest rate swaps entered into
for trading purposes had notional values and estimated fair value gains of $210
million and $152,000, respectively, at December 31, 1997 and notional values and
estimated fair value losses of $50 million and $42,000, respectively, at
December 31, 1996. The Company also entered into foreign exchange and other
option and futures contracts totaling approximately $3.3 billion and $1.6
billion at December 31, 1997 and 1996, respectively. Such contracts were valued
at losses of $214,000 at December 31, 1997 and gains of $1,561,000 at December
31, 1996. All trading account assets and liabilities

16. DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS (CONTINUED)
 
are recorded in the Consolidated Balance Sheet at estimated fair value.

    Due to the near maturity of other money-market assets and short-term 
borrowings, the Company estimates that the carrying value of such instruments 
approximates estimated fair value. The carrying value and estimated fair 
value of long-term borrowings were $427,819,000 and $453,113,000, 
respectively, at December 31, 1997 and $178,002,000 and $180,793,000, 
respectively, at December 31, 1996.
 
    The Company does not believe that the estimated fair value information
presented herein is representative of the earnings power or value of the
Company. The preceding analysis, which is inherently limited in depicting fair
value, also does not consider any value associated with existing customer
relationships nor the ability of the Company to create value through loan
origination, deposit gathering or fee generating activities.
 
    Many of the fair value estimates presented herein are based upon the use of
highly subjective information and assumptions and, accordingly, the results may
not be precise. Management believes that fair value estimates may not be
comparable between financial institutions due to the wide range of permitted
valuation techniques and numerous estimates which must be made.
 
    Furthermore, since the disclosed fair value amounts were estimated as of the
balance sheet date, the amounts actually realized or paid upon maturity or
settlement of the various financial instruments could be significantly
different.
 
17. COMMITMENTS AND CONTINGENCIES
 
    In the normal course of business, various commitments and contingent 
liabilities are outstanding, such as commitments to extend credit guarantees 
and "standby" letters of credit (approximately $193,838,000 and $171,420,000 
at December 31, 1997 and 1996, respectively) which are not reflected in the 
consolidated financial statements. No material losses are expected as a 
result of these transactions. Additionally, the Company had outstanding loan 
commitments of approximately $2.9 billion and $2.7 billion at December 31, 
1997 and 1996, respectively. Because many loan commitments and almost all 
credit guarantees and "standby" letters of credit expire without being funded 
in whole or part, the contract amounts are not estimates of future cash 
flows. Commitments to sell one-to-four family residential mortgage loans 
totaled $266,145,000 at December 31, 1997 and $251,110,000 at December 31, 
1996.
 
    In October 1997, First Empire entered into a definitive agreement with
ONBANCorp, Inc. ("ONBANCorp"), a bank holding company headquartered in Syracuse,
New York, for a merger between the two companies. At December 31, 1997,
ONBANCorp had $5.3 billion of assets. The merger, which will be accounted for as
a purchase, is subject to the approval of stockholders of both companies and is
expected to be accomplished on or about April 1, 1998. Under the terms of the
merger agreement, stockholders of ONBANCorp will have the option to receive .161
of a share of First Empire common stock (and cash in lieu of any fractional
share) or $69.50 in cash in exchange for each share of ONBANCorp common stock.
The merger agreement provides that a minimum of 60% and a maximum of 70% of the
total number of shares of ONBANCorp common stock issued and outstanding
immediately prior to the merger must be exchanged for shares of First Empire
common stock. In the event that ONBANCorp

17. COMMITMENTS AND CONTINGENCIES (CONTINUED)

stockholders as a whole elect to receive stock consideration with respect to 
fewer than 60% or more than 70% of the total number of outstanding shares of 
ONBANCorp common stock, the selection by ONBANCorp common stockholders of the 
method of payment is subject to allocation and proration to ensure that the 
number of shares of ONBANCorp common stock that are converted into shares of 
First Empire common stock will be 60% or 70%, as the case may be, of the 
total number of shares of ONBANCorp common stock issued and outstanding 
immediately prior to the merger. At December 31, 1997 ONBANCorp had 
12,721,689 shares of common stock issued and outstanding.
 
    First Empire and its subsidiaries are subject in the normal course of
business to various pending and threatened legal proceedings in which claims for
monetary damages are asserted. Management, after consultation with legal
counsel, does not anticipate that the aggregate ultimate liability, if any,
arising out of litigation pending against First Empire or its subsidiaries will
be material to the Company's consolidated financial position, but at the present
time is not in a position to determine whether such litigation will have a
material adverse effect on the Company's consolidated results of operations in
any future reporting period.
 
18. REVOLVING CREDIT AGREEMENT OF FIRST EMPIRE
 
    First Empire has a revolving credit agreement with an unaffiliated
commercial bank whereby First Empire may borrow up to $25,000,000 at its
discretion through November 24, 1998. The agreement provides for a facility fee
assessed on the entire amount of the commitment (whether or not utilized)
ranging from .08% to .187% depending on the credit rating of the subordinated
notes of M&T Bank. A usage fee equal to .10% per annum is assessed if the
balance of outstanding loans exceeds 50% of the commitment amount during any
quarter. Under the revolving credit agreement, First Empire may borrow at either
a variable rate based upon the higher of the Federal funds rate plus 1/2 of 1%
or the lender's prime rate, or a fixed rate based upon a premium over LIBOR
ranging from .15% to .30% depending on the credit rating of the subordinated
notes of M&T Bank. At December 31, 1997 and 1996, there were no outstanding
balances under such agreement.
 
19. REGULATORY MATTERS
 
    Payment of dividends by First Empire's banking subsidiaries is restricted by
various legal and regulatory limitations. Dividends from any banking subsidiary
to First Empire are limited by the amount of earnings of the banking subsidiary
in the current year and the preceding two years. For purposes of this test, at
December 31, 1997, approximately $262,187,000 was available for payment of
dividends to First Empire from banking subsidiaries without prior regulatory
approval.
 
    Banking regulations prohibit extensions of credit by the subsidiary banks to
First Empire unless appropriately secured by assets. Securities of affiliates
are not eligible as collateral for this purpose.
 
    The banking subsidiaries are required to maintain noninterest-earning
reserves against certain deposit liabilities. During the maintenance periods
that included December 31, 1997 and 1996, cash and due from banks included a
daily average of $124,132,000 and $128,398,000, respectively, for such purpose.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

19. REGULATORY MATTERS (CONTINUED)

    Federal regulators have adopted capital adequacy guidelines for bank 
holding companies and banks. Failure to meet minimum capital requirements can 
result in certain mandatory, and possibly additional discretionary, actions 
by regulators that, if undertaken, could have a material effect on the 
Company's financial statements. Under the capital adequacy guidelines, the 
so-called "Tier 1 capital" and "Total capital" as a percentage of 
risk-weighted assets and certain off-balance sheet financial instruments must 
be at least 4% and 8%, respectively. In addition to these risk-based 
measures, regulators also require banking institutions that meet certain 
qualitative criteria to maintain a minimum "leverage" ratio of "Tier 1 
capital" to average total assets, adjusted for goodwill and certain other 
items, of at least 3% to be considered adequately capitalized. As of December 
31, 1997, First Empire and each of its banking subsidiaries exceeded all 
applicable capital adequacy requirements.
 
    As of December 31, 1997 and 1996, the most recent notifications from 
federal regulators categorized each of First Empire's banking subsidiaries as 
well capitalized under the regulatory framework for prompt corrective action. 
To be considered well capitalized, a banking institution must maintain Tier 1 
risk-based capital, total risk-based capital and leverage ratios of at least 
6%, 10% and 5%, respectively. Management is unaware of any conditions or 
events since the latest notifications from federal regulators that have 
changed the capital adequacy category of First Empire's banking subsidiaries.
