4.  Contribution of appreciated investment securities

In January 1998, M&T contributed appreciated investment securities with a fair
value of $24.6 million to an affiliated, tax-exempt private charitable
foundation. As a result of this transfer, the Company recognized tax-exempt
other income of $15.3 million and incurred charitable contributions expense of
$24.6 million. These amounts are included in the Consolidated Statement of
Income in "Other revenues from operations" and "Other costs of operations,"
respectively. The transfer provided an income tax benefit of approximately $10.0
million and, accordingly, resulted in an after-tax increase in net income of
$0.7 million.

5.  Acquisition of ONBANCorp, Inc.

On April 1, 1998, M&T consummated the merger ("Merger") of ONBANCorp, Inc.
("ONBANCorp") with and into Olympia Financial Corp.("Olympia"), a wholly owned
subsidiary of M&T. Following the Merger, OnBank & Trust Co., Syracuse, New York,
and Franklin First Savings Bank, Wilkes-Barre, Pennsylvania, both wholly owned
subsidiaries of ONBANCorp, were merged with and into Manufacturers and Traders
Trust Company ("M&T Bank"), M&T's principal banking subsidiary.

After application of the election, allocation and proration procedures contained
in the merger agreement with ONBANCorp, M&T paid $266.3 million in cash and
issued 1,429,998 shares of common stock in exchange for the ONBANCorp common
shares outstanding at the time of acquisition. In addition, based on the merger
agreement and the exchange ratio provided for therein, M&T converted outstanding
and unexercised stock options granted by ONBANCorp into options to purchase
61,772 shares of M&T common stock. The purchase price of the transaction was
approximately $873.6 million based on the cash paid to ONBANCorp stockholders,
the market price of M&T common shares on October 28, 1997 before the terms of
the Merger were agreed to and announced by M&T and ONBANCorp, and the estimated
fair

value of ONBANCorp stock options converted into M&T stock options.

Acquired assets, loans and deposits of ONBANCorp on April 1, 1998 totaled
approximately $5.5 billion, $3.0 billion and $3.8 billion, respectively. The
transaction has been accounted for as a purchase and, accordingly, operations
acquired from ONBANCorp have been included in the Company's financial results
since the acquisition date. In connection with the acquisition, the Company
recorded approximately $501 million of goodwill and $61 million of core deposit
intangible. The goodwill is being amortized on a straight-line basis over twenty
years and the core deposit intangible is being amortized on an accelerated basis
over ten years. The Company incurred expenses related to systems conversions and
other costs of integrating and conforming the acquired operations with and into
the Company of approximately $16.7 million and $18.4 million during the three
and six month periods ended June 30, 1998, respectively. The Company expects to
incur additional integration costs during the remainder of 1998 which will be
expensed as incurred.

Presented below is certain pro forma information as if ONBANCorp had been 
acquired on January 1, 1997. These results combine the historical results of 
ONBANCorp into the Company's Consolidated Statement of Income and, while 
certain adjustments were made for the estimated impact of purchase accounting 
adjustments and other acquisition-related activity, they are not necessarily 
indicative of what would have occurred had the acquisition taken place at 
that time. In particular, expenses related to systems conversions and other 
costs of integration are included in the 1998 periods in which such costs 
were incurred and, additionally, the Company expects to achieve further 
operating cost savings as a result of the Merger which are not reflected in 
the pro forma amounts presented below.

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"), a Delaware business trust organized by the Company on May 30,
1997, issued $100 million of 8.277% preferred capital securities. As a result of
the ONBANCorp acquisition, the Company assumed responsibility for similar
preferred capital securities previously issued by a special-purpose subsidiary
of ONBANCorp. In February 1997, OnBank Capital Trust I ("OnBank Trust I" and,
together with Trust I and Trust II, the "Trusts"), a Delaware business trust
organized by ONBANCorp on January 24, 1997, issued $60 million of 9.25%
preferred capital securities.

Other than the following payment terms (and the redemption terms described
below), the preferred capital securities issued by the Trusts ("Capital

The common securities of Trust I and Trust II are wholly owned by M&T and the
common securities of OnBank Trust I are wholly owned by Olympia. The common
securities of each trust ("Common 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 the Company'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 M&T
in the case of Trust I and Trust II and Olympia in the case of OnBank Trust I:

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 M&T, in the case of Trust I and Trust II, or 
Olympia, in the case of OnBank Trust I, exercise the 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 respective 
Capital Securities will be deferred for a comparable period. During an 
extended interest period, M&T and/or Olympia may not pay dividends or 
distributions on, or repurchase, redeem or acquire any shares of the 
respective company's capital stock. The agreements governing the Capital 
Securities, in the aggregate, provide a full, irrevocable and unconditional 
guarantee by M&T in the case of Trust I and Trust II and Olympia in the case 
of OnBank Trust I of the payment of distributions on, the redemption of, and 
any liquidation distribution with respect to the Capital Securities. The 
obligations under such guarantee and the Capital Securities are subordinate 
and junior in right of payment to all senior indebtedness of M&T and Olympia.

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 OnBank Trust I, and June 1, 2007 in the case of Trust II)
contemporaneously with the Company'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 M&T's option in the 
case of Trust I and Trust II

Item 2.        Management's Discussion and Analysis of Financial Condition and
               Results of Operations.


Overview

Effective May 29, 1998, First Empire State Corporation changed its name to M&T
Bank Corporation ("M&T"). M&T's common stock began trading on the New York Stock
Exchange under the symbol "MTB" on June 1, 1998.

        On April 1, 1998, M&T completed its acquisition of ONBANCorp, Inc. 
("ONBANCorp"), a bank holding company headquartered in Syracuse, New York. 
Immediately after the acquisition, ONBANCorp's two banking subsidiaries, 
OnBank & Trust Co. in Syracuse, which operated 59 offices in upstate New 
York, and Franklin First Savings Bank in Wilkes-Barre, Pennsylvania, which 
operated 19 offices in northeastern Pennsylvania, were merged with and into 
Manufacturers and Traders Trust Company ("M&T Bank"), M&T's principal banking 
subsidiary. The acquisition was accounted for using the purchase method of 
accounting and, accordingly, the operations acquired from ONBANCorp have been 
included in the financial results of M&T and its consolidated subsidiaries 
("the Company") since the acquisition date. ONBANCorp's stockholders received 
$266.3 million in cash and 1,429,998 shares of M&T common stock in exchange 
for ONBANCorp shares outstanding at the time of acquisition. A summary of 
assets acquired and liabilities assumed on April 1, 1998 in connection with 
the ONBANCorp transaction follows (in thousands):

 Total liabilities                                 $4,618,411



        In connection with the acquisition, the Company recorded approximately
$562 million of goodwill and core deposit intangible, and incurred significant
nonrecurring expenses related to systems conversions and other costs of
integrating and conforming the acquired operations with and into M&T Bank. Such
expenses totaled $16.7 million and $18.4 million during the three and six month
periods ended June 30, 1998, respectively. The Company expects to incur
additional integration costs during the remainder of 1998 which will be expensed
as incurred.

        M&T's net income for the second quarter of 1998 was $44.7 million, up 4%
from $42.8 million in the second quarter of 1997. Diluted earnings per common
share were $5.32 in the recent quarter, a decrease of 14% from $6.17 in the
year-earlier quarter. Net income was $49.0 million or $7.01 of diluted earnings
per share in the first quarter of 1998. Basic earnings per share also declined
14% to $5.55 in the second quarter of 1998 from $6.46 in the corresponding 1997
quarter. Basic earnings per share were $7.34 in the initial 1998 quarter. The
after-tax impact on the second quarter of 1998 of nonrecurring expenses
associated with merging the operations of ONBANCorp into the Company was $11.3
million or $1.34 of diluted earnings per share and $1.40 of basic earnings per
share. For the six months ended June 30, 1998, net income was $93.7 million or
$12.16 per diluted share, up 11% and 2%, respectively, from $84.1 million or
$11.98 per share during the first half of 1997. Basic earnings per share were
$12.72 in the first six months of 1998, up from $12.63 in the corresponding 1997
period. Nonrecurring merger-related

                                      -12-



expenses lowered net income during the first half of 1998 by $12.3 million and
diluted and basic earnings per share by $1.59 and $1.66, respectively.

        The annualized rate of return on average assets for the Company in the
second quarter of 1998 was .92%, compared with 1.31% and 1.41% in the second
quarter of 1997 and the first quarter of 1998, respectively. The annualized rate
of return on average common stockholders' equity was 10.77% in the recent
quarter, down from 18.55% in the year-earlier quarter and 18.86% in the initial
1998 quarter. During the first six months of 1998, the annualized rates of
return on average assets and average common stockholders' equity were 1.12% and
13.89%, respectively, compared with 1.30% and 18.40%, respectively, in the
corresponding 1997 period. Excluding the impact of merger-related expenses, the
annualized returns on average assets and average common equity were 1.15% and
13.50%, respectively, during the second quarter of 1998 and 1.27% and 15.70%,
respectively, during 1998's first half.


Cash Operating Results

As a result of the acquisition of ONBANCorp on April 1, 1998 and, to a
significantly lesser extent, acquisitions of other entities in prior years, M&T
had recorded as assets at June 30, 1998 goodwill and core deposit intangible
totaling $566.9 million. Since the amortization of goodwill and core deposit
intangible does not result in a cash expense, M&T believes that reporting its
operating results on a "cash" basis (which excludes the after-tax effect of
amortization of goodwill and core deposit intangible and the related asset
balances) represents a more relevant measure of financial performance and better
reflects the cash return on the investments made by M&T to improve and expand
its franchise. Cash basis data presented herein do not exclude the effect of
non-cash operating expenses such as depreciation, provision for possible credit
losses, or deferred income taxes associated with the results of operations.

        Cash net income, excluding nonrecurring merger-related expenses, was
$65.4 million in the second quarter of 1998, up 48% from $44.4 million in the
year-earlier quarter. On the same basis, diluted earnings per share for the
recent quarter were $7.78, an increase of 22% from $6.40 in the second quarter
of 1997. Cash net income and diluted earnings per share, excluding one-time
expenses, were $51.4 million and $7.37, respectively, in the first quarter of
1998. For the first half of 1998, excluding merger-related expenses, cash net
income and diluted cash earnings per share were $116.9 million and $15.18,
respectively, up 34% and 22%, respectively, from $87.1 million and $12.42 in the
corresponding 1997 period.

        Cash return on average tangible assets, excluding nonrecurring
merger-related expenses, was an annualized 1.38% in the recent quarter, compared
with 1.36% in the second quarter of 1997 and 1.49% in the initial 1998 quarter.
Cash return on average tangible common equity, also before one-time expenses,
was an annualized 23.50% in the second quarter of 1998, up from 19.70% in the
year-earlier quarter and 20.13% in the first quarter of 1998. For the first six
months of 1998, excluding one-time merger-related expenses, the annualized cash
return on average tangible assets and average tangible common stockholders'
equity was 1.43% and 21.89%, respectively, compared with 1.35% and 19.55%,
respectively, in the corresponding 1997 period. As noted earlier, the after-tax
impact of merger-related expenses on net income and diluted earnings per share
was $11.3 million and $1.34, respectively, in the second quarter of 1998 and
$12.3 million and $1.59, respectively, in 1998's first half. Including the
effect of merger-related expenses, the cash return on average tangible assets
for the three and six month periods ended June 30, 1998 was 1.14% and 1.28%,
respectively, and the cash return on average tangible common stockholders'
equity was 19.45% and 19.60%, respectively.


Taxable-equivalent Net Interest Income

Taxable-equivalent net interest income increased to $178.9 million in the second
quarter of 1998, up $39.3 million or 28% from $139.6 million in the year-earlier
quarter and $35.6 million higher than the $143.2 million earned

                                      -13-



in the first quarter of 1998. The most significant factor contributing to the
improvement in net interest income was growth in average loans and leases.
Average loans and leases increased $4.1 billion, or 38%, to $15.0 billion in the
second quarter of 1998 from $10.8 billion in the year-earlier quarter. Average
loans and leases in the recent quarter were $3.4 billion, or 29%, higher than
the first quarter of 1998. The primary reason for the higher loan balances was
the $3.0 billion of loans obtained on April 1, 1998 in the ONBANCorp
acquisition, including approximately $450 million of commercial loans, $380
million of commercial real estate loans, $1.2 billion of residential mortgage
loans and $930 million of consumer loans. The accompanying table summarizes
quarterly changes in the major components of the loan and lease portfolio.

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



         For the first six months of 1998, taxable-equivalent net interest
income was $322.1 million, up from $277.3 million in the corresponding 1997
period. An increase in average loans and leases of $2.5 billion, including
approximately $1.5 billion attributable to the loans acquired in the ONBANCorp
transaction, was the leading factor contributing to this improvement.

         Including approximately $1.4 billion acquired in the ONBANCorp
transaction, average investment securities increased to $2.9 billion in the
recent quarter from $1.7 billion in the second quarter of 1997. Holdings of
investment securities averaged $1.6 billion in the first quarter of 1998.
Money-market assets averaged $156 million in 1998's second quarter, compared
with $143 million in the year-earlier quarter and $141 million in the initial
quarter of 1998. In general, the size of the investment securities and
money-market assets portfolios are influenced by such factors as demand for
loans, which generally yield more than investment securities and money-market
assets, ongoing repayments, the levels of deposits, and management of balance
sheet size and resulting capital ratios.

         As a result of the changes described herein, average earning assets
increased 42% to $18.0 billion in the second quarter of 1998 from $12.7 billion
in the second quarter of 1997. Average earning assets were $13.4 billion in the
first quarter of 1998 and aggregated $15.7 billion and $12.6 billion for the six
months ended June 30, 1998 and 1997, respectively. The impact of
ONBANCorp-related earning assets on average earning assets in the second quarter
and first six months of 1998 was $4.5 billion and $2.3 billion, respectively.

         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 of funding
to the Company and generally carry lower interest rates than wholesale funds of
comparable maturities. The Company's branch network is the principal source of
core deposits. Core deposits include certificates of deposit under $100,000
generated on a nationwide basis by M&T Bank, National Association ("M&T Bank,
N.A."), a wholly owned bank subsidiary of M&T. Core deposits obtained in the
acquisition of ONBANCorp were approximately $2.8 billion on the April 1, 1998
acquisition date. Average core deposits increased to $11.5

                                      -14-





billion in the second quarter of 1998, up from $8.3 billion in the year-earlier
quarter and $8.4 billion in the first quarter of 1998. Average core deposits of
M&T Bank, N.A., were $406 million in the recently completed quarter, compared
with $440 million in the second quarter of 1997 and $433 million in the first
quarter of 1998. The accompanying table provides an analysis of quarterly
changes in the components of average core deposits. For the six months ended
June 30, 1998 and 1997, core deposits averaged $10.0 billion and $8.2 billion,
respectively.

         In addition to core deposits, the Company obtains funding through
domestic time deposits of $100,000 or more, deposits originated through M&T
Bank's offshore branch office, and brokered certificates of deposit. Brokered
deposits are used as an alternative to short-term borrowings to lengthen the
average maturity of interest-bearing liabilities. Brokered deposits averaged
$1.5 billion during the recent quarter and totaled $1.5 billion at June 30,
1998, compared with an average balance of $1.3 billion during the comparable
1997 period and a total balance of $1.5 billion at June 30, 1997. Brokered
deposits also averaged $1.3 billion in the initial quarter of 1998. The weighted
average remaining term to maturity of brokered deposits at June 30, 1998 was
2.08 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 borrowings from banks,
securities dealers, Federal Home Loan Banks ("FHLB") and others as sources of
funding. Short-term borrowings averaged $2.2 billion in the recent quarter
(including $476 million of borrowings assumed as a result of the ONBANCorp
acquisition), compared with $749 million in the second 1997 quarter and $1.4
billion in the first quarter of 1998. Long-term borrowings averaged $695 million
and $355 million in the second quarter of 1998 and 1997, respectively, and $428
million in the first quarter of 1998. During the second 1998 quarter, average
long-term borrowings included $268 million of borrowings obtained in the
ONBANCorp transaction. Long-term borrowings include $250 million of trust
preferred securities issued by two special-purpose subsidiaries of M&T during
the first and second quarters of 1997 and similar securities with a carrying
value of $69 million that were issued in the first quarter of 1997 by a
special-purpose subsidiary of ONBANCorp, as well as $175 million of subordinated
capital notes issued in prior years by M&T Bank.

         Changes in the composition of the Company's earning assets and
interest-bearing liabilities, as well as changes in interest rates and spreads,
can impact net interest income. Net interest spread, or the difference between
the taxable-equivalent yield on earning assets and the rate paid on
interest-bearing liabilities, was 3.44% in the second quarter of 1998, compared
with 3.73% in the year-earlier quarter. The yield on earning assets decreased 28
basis points (hundredths of one percent) to 8.10% in the second quarter of 1998
from 8.38% in the second quarter of 1997. The decrease in the recent quarter's
yield was primarily due to lower yielding residential real estate loans,
consumer loans and investment securities acquired in the ONBANCorp transaction.
The adverse impact of the ONBANCorp-related earning assets on M&T's yield on
earning assets for the second quarter of 1998 was approximately 24 basis points.
The rate paid on interest-bearing liabilities in the second quarter of 1998 was
4.66%,

                                      -15-





compared with 4.65% in the corresponding 1997 quarter. The net interest spread
was 3.68% in the first quarter of 1998 when the yield on earning assets was
8.43% and the rate paid on interest-bearing liabilities was 4.75%.

         The contribution to net interest margin, or taxable equivalent net
interest income expressed as an annualized percentage of average earning assets,
of interest-free funds was .55% in the second quarter of 1998, down from .68% in
the corresponding 1997 quarter and .67% in the first quarter of 1998. Average
interest-free funds, which include noninterest-bearing demand deposits and
stockholders' equity, totaled $2.1 billion in the second quarter of 1998, up
from $1.9 billion a year earlier and in the initial 1998 quarter. The decline in
the contribution to net interest margin of interest-free funds was due, in part,
to the goodwill and core deposit intangible assets recorded in conjunction with
the ONBANCorp acquisition, which averaged $557 million during the recent
quarter, and the Company's ownership of bank-owned life insurance which averaged
$322 million. Although there was no similar investment during the second quarter
of 1997, bank-owned life insurance averaged $204 million during the first
quarter of 1998. Increases in the cash surrender value of bank-owned life
insurance are not included in interest income, but rather are recorded in "other
revenue from operations." These two noninterest-earning assets mitigated much of
the benefit derived from increases in noninterest-bearing deposits and
stockholders' equity resulting from the ONBANCorp transaction.

         Due to the changes described above, the Company's net interest margin
was 3.99% in 1998's second quarter, compared with 4.41% in the comparable
quarter of 1997 and 4.35% in the initial 1998 quarter. During the first six
months of 1998 and 1997, the net interest margin was 4.14% and 4.45%,
respectively.

         The Company utilizes interest rate swap agreements as part of the
management of interest rate risk 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, rates paid on interest-bearing deposits and borrowings. The
notional amount of interest rate swap agreements used as part of the Company's
management of interest rate risk in effect at June 30, 1998 and 1997 was $2.5
billion and $2.9 billion, respectively. 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 the terms of a $33 million swap, the Company pays a fixed rate of
interest and receives a variable rate. At June 30, 1998, the weighted average
rates to be received and paid under interest rate swap agreements were 6.32% and
5.67%, respectively. As of June 30, 1998, the Company had also entered into
forward-starting swaps with an aggregate notional amount of $205 million in
which the Company will pay a fixed rate of interest and receive a variable rate,
and $20 million in which the Company will pay a variable rate of interest and
receive a fixed rate. Such forward-starting swaps had no effect on the Company's
net interest income through June 30, 1998. The average notional amounts of
interest rate swaps and the related effect on net interest income and margin are
presented in the accompanying table.

         The Company estimates that as of June 30, 1998 it would have received
approximately $18 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 recorded in the consolidated financial statements.

         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. Deposits and borrowings, maturities of money-market
assets, repayments of loans and investment securities, and cash generated from
operations, such as net interest income and fees collected for services, provide
the Company with other sources of liquidity. Through membership in the FHLB, as
well as other available borrowing facilities, M&T's banking subsidiaries have
access to additional funding sources. M&T utilizes dividend payments from its
banking subsidiaries, which are subject to various regulatory limitations, to
pay dividends, repurchase treasury stock, and fund debt service and other
operating expenses. The proceeds from $250 million of junior subordinated debt
issued to two special-purpose subsidiaries provided additional funds to M&T in
1997. M&T also maintains a $25 million line of credit with an unaffiliated
commercial bank, all of which was available for borrowing at June 30, 1998.
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
M&T 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. 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 the Company's sensitivity to changes in the market values
of financial instruments resulting from changing interest rates.

         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 actions, 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 displays the estimated impact on net interest
income from financial instruments held for non-trading purposes 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 interest
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.

         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
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 trading activities. However, the Company
generally mitigates exposure arising from trading

                                      -18-





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 June 30, 1998 was not considered material.


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 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
June 30, 1998 was adequate to absorb credit losses from existing loans and
leases.

         The provision for possible credit losses in the second quarter of 1998
was $13.2 million, up from $11.0 million in the second quarter of 1997 and $12.0
million in 1998's first quarter. Net loan charge-offs totaled $9.0 million in
the second quarter of 1998, compared with $12.6 million in the year-earlier
quarter and $7.9 million in 1998's initial quarter. Net charge-offs as an
annualized percentage of average loans and leases were .24% in the recent
quarter, compared with .47% in the corresponding 1997 quarter and .28% in the
first quarter of 1998. Net charge-offs of consumer loans in the recent quarter
were $9.3 million, compared with $9.7 million in the second quarter of 1997 and
$7.8 million in 1998's initial quarter. Net consumer loan charge-offs as an
annualized percentage of average consumer loans and leases were 1.21% in the
recent quarter, compared with 1.68% in the second quarter of 1997 and 1.45% in
1998's first quarter. Net charge-offs of credit card balances included in net
consumer loan charge-offs were $4.6 million and $5.1 million in the second
quarter of 1998 and 1997, respectively, and $4.5 million in the first quarter of
1998. For the six months ended June 30, 1998 and 1997, the provision for
possible credit losses was $25.2 million and $22.0 million, respectively.
Through June 30, net charge-offs were $17.0 million in 1998 and $20.5 million in
1997, representing .26% and .38%, respectively, of average loans and leases.
Consumer loan net charge-offs totaled $17.1 million and $18.5 million during the
six months ended June 30, 1998 and 1997, respectively. Net credit card
charge-offs were $9.2 million during the first half of 1998 and $9.9 million
during the corresponding 1997 period.

         Including $38.4 million of loans obtained in the acquisition of
ONBANCorp, nonperforming loans were $127.2 million or .83% of total loans and
leases outstanding at June 30, 1998, compared with $97.1 million or .88% at June
30, 1997 and $70.0 million or .58% at March 31, 1998. Nonperforming commercial
real estate loans totaled $24.8 million at June 30, 1998, $29.2 million at June
30, 1997 and $10.7 million at March 31, 1998. Nonperforming commercial real
estate loans include loans secured by properties located in the New York City
metropolitan area of $3.6 million at June 30, 1998, $11.9 million at June 30,
1997 and $206 thousand at March 31, 1998. Nonperforming consumer loans and
leases totaled $30.0 million at June 30, 1998, compared with $16.4 million at
June 30, 1997 and $19.5 million at March 31, 1998. As a percentage of consumer
loan balances outstanding, nonperforming consumer loans and leases were .99% at
June 30, 1998 compared with .71% at June 30, 1997 and .90% at March 31, 1998.
Assets acquired in settlement of defaulted loans were $12.2 million at June 30,
1998, $9.7 million at June 30, 1997 and $7.8 million at March 31, 1998.

         A comparative summary of nonperforming assets and certain credit
quality ratios is presented in the accompanying table.

         The allowance for possible credit losses was $310.8 million, or 2.04%
of total loans and leases at June 30, 1998, compared with $271.9 million or
2.48% a year earlier, $274.7 million or 2.39% at December 31, 1997 and $278.7
million or 2.32% at March 31, 1998. The ratio of the allowance for possible
credit losses to nonperforming loans was 244% at the most recent quarter-end,
compared with 280% a year earlier, 341% at December 31, 1997 and 398% at March
31, 1998.


Other Income

Reflecting strong growth in mortgage banking revenues, fees for trust and
investment services, and approximately $7.6 million of revenues associated with
operations obtained in the ONBANCorp acquisition, other income totaled $66.4
million in the second quarter of 1998, up 51% from $44.0 million in the
year-earlier quarter. Other income was $55.1 million in the first quarter of
1998 excluding $15.3 million of tax-exempt other income the Company recognized
in connection with the contribution of appreciated investment securities with a
fair value of $24.6 million to an affiliated, tax-exempt private charitable
foundation. As a result of the transfer, the Company also incurred $24.6 million
of charitable contributions expense and realized income tax benefits of $10.0
million. Also excluding the effect of the transfer, other income was $121.5
million in the first half of 1998, up 35% from $89.9 million in the comparable
1997 period.

         Including $2.1 million of revenues associated with acquired ONBANCorp
operations, mortgage banking revenues totaled $18.5 million in the recent
quarter, compared with $12.2 million in the year-earlier quarter and $13.9
million in the first quarter of 1998. Residential mortgage loan servicing fees
were $7.8 million in the second quarter of 1998, up from $6.2 million in the
second quarter of 1997 and $7.2 million in the initial 1998 quarter. Gains from
sales of residential mortgage loans and loan servicing rights were $9.9 million
in the recently completed quarter, compared with $5.4 million in the
year-earlier quarter and $5.9 million in 1998's first quarter. During the recent
quarter, the Company completed bulk sales of servicing rights related to
approximately $400 million of loans sold to investors in prior periods resulting
in a gain of $1.2 million. Due, in part, to generally favorable interest rates
for borrowers, during the second quarter of 1998 residential mortgage loans
originated for sale to other investors totaled $953 million, up from $505
million in 1997's second quarter and $775 million in the initial 1998 quarter.
Residential mortgage loans serviced for others

                                      -20-





totaled $8.1 billion and $6.5 billion at June 30, 1998 and 1997, respectively.
Capitalized servicing assets were $67 million and $49 million at June 30, 1998
and 1997, respectively. Loans serviced for others and the related capitalized
servicing assets obtained in the ONBANCorp acquisition were $988 million and $16
million, respectively, at April 1, 1998.

         Service charges on deposit accounts increased to $14.2 million in the
second quarter of 1998, up from $10.7 million in the corresponding quarter of
the previous year and $11.2 million in the first quarter of 1998. Fees for
services provided to customers in the areas formerly served by ONBANCorp were
$2.6 million in the recent quarter. Largely due to higher revenues for
management, custody and securities clearing services, trust income was $9.9
million in the second quarter of 1998, compared with $7.2 million in last year's
second quarter. Trust income was $9.5 million during the first three months of
1998. Merchant discount and credit card fees were $4.3 million in the recent
quarter, compared with $4.2 million in both the year-earlier period and in the
initial 1998 quarter. Trading account and foreign exchange activity resulted in
gains of $506 thousand in the second quarter of 1998, compared with gains of
$596 thousand and $1.8 million in the second quarter of 1997 and the first
quarter of 1998, respectively. Other revenue from operations totaled $18.7
million in the recent quarter, compared with $9.2 million in the corresponding
quarter of 1997 and $14.5 million in the first quarter of 1998 (excluding the
$15.3 million of tax-exempt income related to the transfer of securities to the
Company's affiliated foundation). Included in other revenue from operations in
1998's second quarter was $1.5 million relating to ONBANCorp-related activities.
The remaining increase from the year-earlier period was due largely to $4.5
million of tax-exempt income earned from the Company's ownership of bank-owned
life insurance, higher fees earned from the sales of mutual funds and annuities
of $1.2 million, $1.1 million in fees for providing automated teller machine
services and higher miscellaneous loan fees of $1.0 million.

         For the six-month period ended June 30, 1998, mortgage banking revenues
totaled $32.3 million, up 33% from $24.2 million in the corresponding 1997
period. Compared with the first half of 1997, mortgage servicing fees and gains
from sales of loans and loan servicing rights in 1998 were up by $2.9 million
and $4.9 million, respectively. Compared with the same period in 1997, service
charges on deposit accounts increased 20% to $25.4 million during the first six
months of 1998, while trust income increased 37% to $19.4 million. As a result
of the factors discussed in the next paragraph, merchant discount and credit
card fees decreased 9% to $8.6 million from $9.5 million in the similar period
of 1997. Trading account and foreign exchange activity resulted in gains of $2.3
million for the initial half of 1998, compared with gains of $1.9 million during
the first six months of 1997. Excluding the effect of the transfer of securities
to the affiliated charitable foundation, other revenues from operations
increased 73% to $33.2 million in the first six months of 1998 from $19.2
million in the comparable 1997 period. The increase resulted largely from $7.4
million of tax-exempt income earned from bank-owned life insurance, $2.3 million
of increased loan fees, $1.6 million in automated teller machine service fees
and a $1.5 million increase in fees earned from the sales of mutual funds and
annuities. These latter fees totaled $8.9 million during the first half of 1998.

         Due to poorer than expected results, during 1997 and 1998 the 
Company terminated all of its co-branded credit card programs. In addition, 
during the recently completed quarter, M&T agreed to sell its retail credit 
card business. The sale occurred on July 31, 1998 and resulted in a third 
quarter pre-tax gain of approximately $3 million. Following the sale, M&T 
continues to offer credit cards to customers in the name of M&T Bank, but the 
cardholder accounts are owned and serviced by the purchaser of that business. 
Credit card balances outstanding were $205.5 million, or 1.35% of total loans 
and leases, at June 30, 1998. Total credit card fees included in merchant 
discount and credit card fees in the first half of 1998 were $6.9 million, 
compared with $7.9 million in the corresponding 1997 period. Including 
internal allocations of the provision for possible credit losses, interest 
expense and other operating expenses, net income from credit card operations 
was less than 1.5% of the Company's net income during the first six months of 
1998.

                                      -21-




Other Expense

Excluding the impact of the $24.6 million of contributions expense already
discussed, amortization of goodwill and core deposit intangible, and
nonrecurring merger-related expenses, other expense totaled $127.4 million in
the second quarter of 1998, up 27% from $100.2 million in the second quarter of
1997 and 20% from $105.8 million in the first quarter of 1998. On the same
basis, through the first half of 1998, other expense totaled $233.2 million, an
increase of 15% from $202.7 million in the comparable 1997 period. Nonrecurring
merger-related expenses were $16.7 million and $1.6 million during the second
and first quarters of 1998, respectively. Increases in operating expense levels
compared with prior periods is predominately the effect of combining ONBANCorp
with the Company. Since nearly all operating systems and support operations of
ONBANCorp were converted to or combined with those of the Company during the
recent quarter, the Company's operating expenses cannot be precisely divided
between or attributed directly to ONBANCorp or the Company as it existed prior
to the merger.

         Salaries and employee benefits expense was $69.9 million in the recent
quarter, 31% higher than the $53.6 million in the corresponding 1997 quarter,
and 20% higher than the $58.3 million in the first quarter of 1998. For the
first six months of 1998, salaries and employee benefits expense increased 18%
to $128.3 million from $109.1 million in the corresponding 1997 period. Salaries
and employee benefits relating to the operations acquired from ONBANCorp were
the predominant factor for the increased expense level. Other factors
contributing to the higher expenses were merit salary increases and higher costs
associated with incentive-based compensation arrangements, stock appreciation
rights and employee benefits.

         Excluding the previously mentioned $24.6 million of contributions
expense recognized in the first quarter of 1998, one-time merger-related
expenses and amortization of goodwill and core deposit intangible, nonpersonnel
expense totaled $58.8 million in the second quarter of 1998, up from $46.7
million in the second quarter of 1997 and $47.5 million in the first quarter of
1998. On the same basis, such expenses were $106.3 million during the first six
months of 1998, an increase of 14% from $93.6 million during the corresponding
1997 period. The increases were the result of expenses related to the acquired
operations of ONBANCorp. Partially offsetting these increases were decreases in
co-branded credit card rebate and other operating expenses based on card usage
of $1.5 million and $1.7 million compared with the second quarter of 1997 and
the first quarter of 1998, respectively. Such expenses for the first half of
1998 were $2.6 million, compared with $6.1 million in the corresponding 1997
period.


Capital

Stockholders' equity at June 30, 1998 was $1.7 billion or 8.24% of total assets,
compared with $951 million or 7.08% of total assets a year earlier and $1.0
billion or 7.36% at December 31, 1997. On a per share basis, stockholders'
equity was $207.18 at June 30, 1998, up from $143.64 and $155.86 at June 30 and
December 31, 1997, respectively. Excluding goodwill and core deposit intangible,
net of applicable tax effect, tangible equity per share was $139.37 at June 30,
1998, compared with $140.43 at June 30, 1997 and $153.24 at December 31, 1997.
To complete the acquisition of ONBANCorp on April 1, 1998, M&T issued 1,429,998
shares of common stock to former holders of ONBANCorp common stock and assumed
employee stock options for 61,772 shares of M&T common stock resulting in
additions to stockholders' equity of $587.8 million and $19.4 million,
respectively.

         Stockholders' equity at June 30, 1998 reflected a gain of $6.6 million,
or $.83 per share, for the net after-tax impact of unrealized gains on
investment securities classified as available for sale, compared with unrealized
gains of $3.4 million or $.52 per share at June 30, 1997 and $12.0 million or
$1.82 per share at December 31, 1997. Such unrealized gains 



                                      -22-



represent the difference, net of applicable income tax effect, between the 
estimated fair value and amortized cost of investment securities classified 
as available for sale. 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.

         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 capital. Core capital includes
the $250 million of trust preferred securities issued by two special-purpose
subsidiaries of M&T in the first and second quarters of 1997 and similar
securities having a carrying value of $69 million issued in February 1997 by a
special-purpose subsidiary of ONBANCorp. As of June 30, 1998, total capital also
included $160 million of subordinated notes issued by M&T Bank in prior years.
Unrealized gains or losses on investment securities are not recognized in
determining regulatory capital. The capital ratios of the Company and its
banking subsidiaries, M&T Bank and M&T Bank, N.A., as of June 30, 1998 are
presented in the accompanying table.

         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 less
dividends paid expressed as an annualized percentage of average total
stockholders' equity, was 8.84% during the second quarter of 1998, compared with
16.25% in the second quarter of 1997 and 16.80% in the initial 1998 quarter.

         During the second quarter of 1998, M&T acquired 88,438 shares of its
common stock pursuant to, and thereby completing, the repurchase program
announced in February 1997. A total of 303,317 shares were repurchased at an
average cost of $398.27 per share. In May 1998, M&T announced another plan to
repurchase up to 155,133 additional shares for reissuance upon the possible
future exercise of outstanding stock options. As of June 30, 1998, M&T had
repurchased 25,155 common shares pursuant to the latest plan at an average cost
of $515.56 per share. M&T repurchased 150,461 common shares during the first six
months of 1998 at a total cost of $74.7 million.

Year 2000 Initiatives

     The "Year 2000" problem relates to the ability of computer and 
computer-dependent systems to distinguish date data between the twentieth and 
twenty-first centuries. The Company is currently working to resolve the 
potential impact of the Year 2000 problem. The risk for the Company is that 
all of the corrections and testing will not be made in time for its own 
computer, data processing or other computer-dependent systems, and for those
third parties doing business with or providing services to the Company.

     Addressing the Year 2000 problem requires that the Company identify, 
remediate and test its centalized and distributed computer, data processing


                                    -23-


and other computer-dependent systems that have date sensitive functions. 
Management anticipates that the Company's "mission critical" computer 
systems, i.e., those which if uncorrected would have a material adverse 
impact on the Company, will be Year 2000 compliant by the end of 1998 and has 
a planned program to test for such compliance. As a result of completed 
testing, management presently believes that approximately one-third of its 
centralized computer systems are Year 2000 compliant. The Company is also 
engaged in an ongoing process of assessing, correcting and testing its 
distributed computer and other computer-dependent systems which may be 
affected by the Year 2000 problem. The Company currently expects to make 
mission critical distributed computer and other computer-dependent systems 
Year 2000 compliant or to replace such non-compliant systems before the new 
millenium.

     The Company could be adversely affected if its vendors and customers 
that supply or rely on data processing systems 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. Specifically, lending 
officers have been trained to address Year 2000 issues with customers, 
including providing help with assessing customer needs for Year 2000 
compliance. Notwithstanding the Company's efforts, a risk remains due to the 
uncertainty that such third parties will not be Year 2000 compliant before 
the new millennium. For example, the credit quality of commercial and other 
loans may be adversely affected by the failure of customers' operating 
systems resulting from Year 2000 issues.

     Lack of corrective measures by government agencies or service providers 
which the Company either receives data from or provides data to could also 
have a negative impact on the Company's operations. Additionally, there is 
risk to the extent that other third parties that engage in business with the 
Company are relying on systems that are not Year 2000 compliant. As a result, 
it is possible that if all aspects of Year 2000 issues are not adequately 
resolved by each of the entities referred to above, the Company's future 
business operations, financial position and results of operations could be 
adversely impacted.

     The Company's management is monitoring the Company's progress regarding 
Year 2000 issues. Management will assess the Company's current Year 2000 
remediation plans and develop appropriate contingency plans should any 
critical issues not be resolved prior to January 1, 2000.

      To date, the Company has spent approximately $2 million in addressing 
its potential Year 2000 problems. The Company is continuing to devote 
appropriate financial and human resources to resolve its Year 2000 issues in 
a timely manner. The Company currently estimates that it will expend an 
additional $3 to $5 million in order to address Year 2000 issues. A majority 
of the Company's past and future Year 2000 expenses relate to internal costs 
and constitute resources that would otherwise have been reallocated within 
the Company. Costs associated with Year 2000 issues are recognized as 
expenses are incurred.

     The preceding discussion of Year 2000 initiatives contains 
forward-looking statements as to Year 2000 issues. See also the discussion of 
Future Factors under the caption "Forward-Looking Statements," which are 
incorporated by reference into the preceding discussion.

Recently issued accounting standards not yet adopted

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts, and for hedging activities. It requires
that an entity recognize all derivatives as either assets or liabilities in the
balance sheet and measure those instruments at fair value. If certain conditions
are met, a derivative may be specifically designated as 


                                     -24-


(a) a hedge of the exposure to changes in the fair value of a recognized 
asset or liability or an unrecognized firm commitment, (b) a hedge of the 
exposure to variable cash flows of a forecasted transaction, or (c) a hedge 
of the foreign currency exposure of a net investment in a foreign operation, 
an unrecognized firm commitment, an available for sale security, or a foreign 
currency denominated forecasted transaction.

         The accounting for changes in the fair value of a derivative depends on
the intended use of the derivative and the resulting designation. An entity that
elects to apply hedge accounting is required to establish at the inception of
the hedge the method it will use for assessing the effectiveness of the hedging
derivative and the measurement approach for determining the ineffective aspect
of the hedge. Those methods must be consistent with the entity's approach to
managing risk.

         SFAS No. 133 is effective for all fiscal quarters of fiscal years
beginning after June 15, 1999. Initial application of SFAS No. 133 should be as
of the beginning of an entity's fiscal quarter; on that date, hedging
relationships must be designated anew and documented pursuant to the provisions
of the statement. Early application of all of the provisions of SFAS No. 133 is
encouraged, but is permitted only as of the beginning of any fiscal quarter that
begins after issuance of the statement. SFAS No. 133 should not be applied
retroactively to financial statements of prior periods.

         The Company is currently in the process of analyzing the provisions of
SFAS No. 133.  The method of adoption expected to be utilized by the Company
and the impact that adopting the provisions of SFAS No. 133 is expected to
have on the Company's financial statements has yet to be determined.


Forward-Looking Statements

Management's Discussion and Analysis of Financial Condition and Results of
Operations and other sections of this quarterly report contain forward-looking
statements that are based on current expectations, estimates and projections
about the Company's business, management's beliefs and assumptions made by
management. These statements are not guarantees of future performance and
involve certain risks, uncertainties and assumptions ("Future Factors") which
are difficult to predict. Therefore, actual outcomes and results may differ
materially from what is expressed or forecasted in such forward-looking
statements. The Company undertakes no obligation to update publicly any
forward-looking statements, whether as a result of new information, future
events or otherwise.

         Future Factors include changes in interest rates, spreads on earning
assets and interest-bearing liabilities, and interest rate sensitivity; credit
losses; sources of liquidity; regulatory supervision and oversight, including
required capital levels; increasing price and product/service competition by
competitors, including new entrants; rapid technological developments and
changes; the ability to continue to introduce competitive new products and
services on a timely, cost-effective basis; the mix of products/services;
containing costs and expenses; governmental and public policy changes, including
environmental regulations; protection and validity of intellectual property
rights; reliance on large customers; technological, implementation and
cost/financial risks in large, multi-year contracts; technological,
implementation and financial risks associated with Year 2000 issues; the outcome

Item 3. Quantitative and Qualitative Disclosures About Market Risk

         Incorporated by reference to the discussion contained under the caption
"Taxable-equivalent Net Interest Income" in Part I, Item 2, "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

                           PART II. OTHER INFORMATION

Item 1. Legal Proceedings.

         M&T 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 M&T or its subsidiaries will be material to M&T'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 M&T's
consolidated results of operations in any future reporting period.

Item 2. Changes in Securities and Use of Proceeds.
           (Not applicable.)

Item 3. Defaults Upon Senior Securities.
            (Not applicable.)

Item 4. Submission of Matters to a Vote of Security Holders.
