(e) Notwithstanding anything in this Agreement to the
contrary, it is expressly understood and agreed by the parties hereto that the
consummation of the Subordinated Debt Exchange and the issuance of the Amended
Subordinated Notes shall 

5

not constitute
a waiver or release of the Subordinated Creditors claims against the Borrower
with respect to the costs and expenses incurred to date in connection with
efforts to collect amounts pursuant to, or enforce their rights with respect
to, the Subordinated Notes.

          3.
Acknowledgement of Subordinated Creditors. Each Subordinated Creditor hereby agrees and
acknowledges (for the benefit of Agent, the Senior Lenders and each Company) as
follows:

                              
(a) Each Subordinated Creditor hereby (i) ratifies and
reaffirms the continued subordination of the Subordinated Debt (including, all
Subordinated Debt evidenced by the Amended Subordinated Notes) to the Senior
Debt (including any Refinancing Senior Debt, which may be in a principal amount
reasonably greater than the Senior Debt outstanding under the VPC Loan
Documents) in accordance with, and its liabilities, obligations and agreements
under, the terms of the Subordination Agreement, (ii) acknowledges that (a) it
has no defenses, claims or setoffs to the enforcement by the Agent or the
Senior Lenders of the liabilities, obligations and agreements of such
Subordinated Creditor thereunder and (b) neither the Agent nor any Senior
Lenders waives, diminishes or limits any term or condition contained in the
Subordination Agreement and (iii) agrees that the Subordination Agreement, the
subordination effected thereby and the rights and obligations of the
Subordinated Creditors, the Agent, the Senior Lenders and the Obligors arising
thereunder shall not be affected, modified or impaired in any manner or to any
extent by the Sixth Forbearance Agreement, any other forbearance agreement or
the transactions contemplated thereby.

                              
(b)  Each
Subordinated Creditor agrees that, so long as Borrower is not in material
breach of its obligations hereunder, each Subordinated Creditor shall cooperate
with Borrower, the other Obligors and their respective designees to assist
Borrower in consummating, and shall not interfere with, Borrower’s refinancing
of the Senior Debt, or the consummation of an underwritten initial public offering
of Borrower’s shares of Common Stock pursuant to an effective registration
statement filed under the Securities Act (an “IPO”). Such cooperation and non-interference shall include, without
limitation, the execution and delivery by each Subordinated Creditor of a
subordination agreement with any lenders providing the Refinancing Senior Debt
with terms not materially less favorable to the Subordinated Creditor than
those set forth in the Subordination Agreement; but shall not include any
obligation (i) to agree to any modifications to the economic terms of the
Subordinated Debt that are materially less favorable to the Subordinated
Creditors than the economic terms applicable to the Subordinated Debt (as in
effect on the date hereof, after giving effect to this Agreement) or (ii) to
enter into any other agreement, the effect of which is to subordinate the
Subordinated Debt to the Refinancing Senior Debt in a manner materially less
favorable to the Subordinated Creditors than either (x) the subordination
provisions set forth in the Subordination Agreement (as in effect on the date
hereof) or (y) the subordination 

6

provisions
agreed to among the Refinancing Agent and the other subordinated creditors of
Borrower (other than the subordination provisions relating to any lien
priority). Each Subordinated Creditor
acknowledges that any such interference or lack of cooperation will cause
irreparable harm to the Agent and the Senior Lenders and shall entitle them to seek
injunctive relief in addition to any other remedies at law or equity to which
Agent or any Senior Lenders may be entitled.

          4.
Acknowledgement Regarding Subordinated Debt. The Obligors hereby agree and acknowledge
for the benefit of each of the Subordinated Creditors as follows:

                              
(a) Each of the Obligors hereby (i) ratifies and
reaffirms the continued validity and existence of the Subordinated Debt, (ii)
acknowledges that (a) it has no defenses, claims or setoffs to the enforcement
by the Subordinated Creditors of the Subordinated Debt, and (b) subject to the
Subordination Agreement, none of the Subordinated Creditors waives, diminishes
or limits any term or condition contained in the Subordinated Debt and (iii)
agrees that, except as expressly agreed to by the Subordinated Creditors
pursuant to this Agreement, the Subordinated Debt shall not be affected,
modified or impaired in any manner or to any extent by the Sixth Forbearance
Agreement, any other forbearance agreement or the transactions contemplated
thereby.

                              (b)
Each of the Obligors hereby agrees that it shall pay
(or cause Borrower to pay) all net proceeds from any IPO (after payment in full
of the Senior Debt and less the reasonable, actual costs and expenses including
underwriting commissions), of the IPO payable by the Borrower) to the
Subordinated Creditors; provided, that, in the event the net proceeds of an IPO
are insufficient to pay in full all of the Subordinated Debt (after payment in
full of the Senior Debt), the Obligors shall cooperate with the Subordinated
Creditors and all other secured creditors and their respective designees and
take all actions reasonably necessary or appropriate to cause Obligors to pay
in full the outstanding Subordinated Debt prior to any payment to any other
creditor, or payment of any bonus, deferred compensation, severance or similar
such payments.

Company for payment and/or delivery thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust property, and all liability of the Company as trustee thereof,
shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being

Adjustment or a mandatory exchange for M&T Common Stock, for the purpose of exchange and for all

or any Paying Agent shall have any responsibility or liability for any aspect of the records
relating to or payments made on account of beneficial ownership interests in the Global Note or for
maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

     Notwithstanding the foregoing, with respect to any Global Note, nothing herein shall prevent
the Company, the Trustee, any Paying Agent, or any agent of the Company, the Trustee or any Paying
Agent, from giving effect to any written certification, proxy or other authorization furnished by
DTC, as a Holder, with respect to such Global Note or impair, as between DTC and owners of
beneficial interests in such Global Note, the operation of customary practices governing the
exercise of the rights of DTC (or its nominee) as Holder of such Global Note.

of one or more Global Notes, which shall be deposited on behalf of the purchasers of the Notes
represented thereby with DTC or any DTC Custodian, as custodian for DTC, and registered in the name
of DTC’s nominee, Cede & Co., duly executed by the Company and authenticated by the Trustee as
hereinafter provided.

     (b) Each Global Note shall represent such of the Outstanding Notes as shall be specified
therein and each shall provide that it shall represent the

13

 

aggregate number of Outstanding Notes from time to time endorsed thereon and that the
aggregate number of Outstanding Notes represented thereby may from time to time be reduced or
increased, as appropriate, to reflect redemption, mandatory exchange for M&T Common Stock or other
exchanges of such Notes. Any endorsement of a Global Note to reflect the amount of any increase or
decrease in the number of Outstanding Notes represented thereby shall be made by the Trustee or the
DTC Custodian in accordance with the standing instructions and procedures existing between the
Trustee and the DTC Custodian.

     (c) If DTC elects to discontinue its services as securities depositary with respect to the
Global Notes, the Company may, in its sole discretion, appoint a successor Depositary with respect

of Notes represented by such Global Note or portion thereof to be so exchanged, shall be registered
in such names and be in such authorized denominations as DTC shall designate and shall bear the
applicable legends provided in the Indenture. Any Global Note to be exchanged in whole shall be
surrendered by DTC to the Trustee or the Senior Debt Security Registrar. With regard to any Global
Note to be exchanged in part, either such Global Note shall be so surrendered for exchange or, if
the Trustee is acting as custodian for DTC or its nominee with respect to such Global Note, the
number of Notes represented thereby shall be reduced, by a number equal to the number of Notes
represented by the portion thereof to be so exchanged, by means of an endorsement on the Global
Note to reflect such reduction and an appropriate adjustment made on the records of the Trustee.
Upon any such surrender or adjustment, the Trustee shall authenticate and deliver the Notes
issuable on such exchange to or upon the order of DTC or an authorized representative thereof.

     (f) Subject to the provisions of Section 2.07(g) below, the registered Holders of the Notes

hold interests through Agent Members, to take any action that a Holder of the Notes is entitled to
take under the Indenture or the Notes.

     (g) Neither any member of DTC or any DTC Participant (collectively, the “Agent Members”) nor
any other Persons on whose behalf Agent Members may act shall have any rights under the Indenture
with respect to any Global Note registered in the name of DTC or any nominee thereof or under any
such Global

14

 

Note. DTC or such nominee, as the case may be, may be treated by the Company, the Trustee and
any agent of the Company or the Trustee as the absolute owner and Holder of such Global Note for
all purposes whatsoever. Notwithstanding the foregoing, with respect to any Global Note, nothing
herein shall prevent the Company or the Trustee or any agent of the Company or the Trustee from
giving effect to any written certification, proxy or other authorization furnished by DTC or such
nominee, as the case may be, or impair, as between DTC, its Agent Members and any other Person on
whose behalf an Agent Member may act, the operation of customary practices of such Persons
governing the exercise of the rights of DTC or such nominee as Holder of such Global Note.

paid to Holders of the Notes in connection with the Indenture and the Notes shall be rounded to the

returned to the Record Date Holders with respect to a Cash M&T Distribution Adjustment, if any,
which is to be retained in the Control Account held with the Bank.

Stock certificate representing a number of shares of M&T Common Stock equal to the product of the
Exchange Ratio as of the Exchange Date and the number of the Outstanding Notes with appropriate
instructions to issue M&T Common Stock in book-entry form to the Exchange Date Holders through DTC
and (ii) to the Trustee, for the benefit of the Exchange Date Holders, cash in lieu of any
fractional shares of M&T Common Stock pursuant to Section 3.06. Upon delivery of the M&T Common
Stock to M&T’s stock transfer agent for cancellation, the Company shall promptly provide notice of
such delivery to the Trustee (the “Cancellation Notice”).

16

 

     (d) If the Exchange Condition is satisfied but a Regulatory Event occurs, the Company shall by
9:30 a.m. (New York City time) on the Exchange Date (i) issue a press release stating that a
Regulatory Event has occurred and (ii) provide written notice to the Trustee and M&T’s stock
transfer agent that a Regulatory Event has occurred and that the Company will not deliver M&T
Common Stock to M&T’s stock transfer agent for transfer to the Exchange Date Holders. The Trustee

receives the foregoing written notice.

     (e) The Company’s delivery of M&T Common Stock in connection with a mandatory exchange of the
Notes to M&T’s stock transfer agent pursuant to Section 3.02 and this Section 3.03 shall be
irrevocable. Upon delivery of M&T Common Stock pursuant to clause (c) above, the Company shall have
no further rights or other ownership interest with respect to such M&T Common Stock.

     (f) Subject to the foregoing, upon book-entry transfer of the Notes or delivery of the Notes
to the Trustee with duly completed transfer instructions on or after the Exchange Date, the
Trustee, subject to receipt of the Cancellation Notice, shall authorize the delivery through DTC of
the shares of M&T Common Stock into which such Notes are exchangeable, but without any interest
thereon, to the Exchange Date Holders by book-entry transfer, or other appropriate procedures, in
accordance with such instructions.

     (g) Such shares of M&T Common Stock shall be registered in the name of the Exchange Date
Holder or the Exchange Date Holder’s designee as specified in the exchange instructions provided by
the Holder to the Trustee.

     (h) In the event an Exchange Date Holder fails to effect such transfer or delivery in
accordance with clause (f) above, the shares of M&T Common Stock underlying such Notes and any
distributions on such shares of M&T Common Stock, shall be held in trust for the benefit of such
Exchange Date Holder, until the earlier to occur of:

     (i) the surrender of the Note or receipt by the Company and the Trustee

Adjustment and/or to make a transfer in connection with any Non-cash M&T Distribution
Adjustment or (ii) any rights the Record Date Holders have to receive any payment in connection

City time) on the Exchange Date of the occurrence of a Regulatory Event, each Outstanding Note
shall be redeemed on the Maturity Date for its applicable Redemption Price on such date. Upon the
occurrence of any of the events in clauses (i), (ii) or (iii) above, the Trustee shall promptly
notify DTC, as the Holder of the Notes, that the Outstanding Notes are to be redeemed on the
Maturity Date.

     (b) The Company shall provide written notice to the Trustee and the Paying Agent by the open
of business on the Maturity Date notifying the Trustee and the Paying Agent of (i) the amount, if
any, by which the Redemption Price has changed from the initial Redemption Price (such
determination to be made by the Company) and (ii) the aggregate cash amount (including the cash
amount per Note) to be returned to the Record Date Holders with respect to a Cash M&T Distribution
Adjustment, if any, that is to be retained in the Control Account.

     (c) For the avoidance of doubt, the redemption of Notes pursuant to this Section 3.04 shall be
in whole and not in part.

     Section 3.05. Obligations In Connection With Mandatory Redemption. (a) If the Outstanding
Notes are to be redeemed on the Maturity Date, an amount of cash equal to the aggregate Redemption
Price (as of the Maturity Date) shall be delivered from the Control Account to the Trustee or

credited to an account at DTC in the name of the Trustee (or its nominee) or the Paying Agent for
the benefit of the Holders.

     (b) Subject to the foregoing, upon book-entry transfer of the Notes or delivery of a Note to

wire transfer, or other appropriate procedures, in accordance with such instructions.

     (c) If a Holder fails to effect such transfer or delivery in accordance with clause (b) above,
an amount equal to the aggregate Redemption Price (as of the Maturity Date) of such Holder’s Notes,
shall be held by the Trustee or the Paying Agent in trust for the benefit of such Holder, until the
earlier to occur of:

     (i) the surrender of the Note or receipt by the Company and the Trustee
from such Holder of satisfactory evidence that such Note has been destroyed, lost or
stolen, together with any indemnity that may be reasonably required by the Trustee and the
Company; and

     (ii) the expiration of the time period specified in the abandoned property
laws of the relevant jurisdiction.

     (d) For the avoidance of doubt, the redemption of Notes on the Maturity Date pursuant to
Section 3.04 and this Section 3.05 shall not terminate or extinguish (i) the Company’s obligations,
if any, to make a payment in connection with any Cash M&T Distribution Adjustment or (ii) any
rights the Record Date Holders have to receive any payment in connection with a Cash M&T
Distribution Adjustment, pursuant to Section 4.02.

     Section 3.06. No Fractional Shares. (a) No fractional shares of M&T Common Stock shall be
delivered in connection with a mandatory exchange of the Notes on the Exchange Date pursuant to
Section 3.02 and Section 3.03. Instead the Company, through the Trustee, shall make a cash payment
on the Exchange Date in lieu of any fractional shares based on the Closing Sale Price of the shares
of M&T Common Stock on the Trading Day immediately prior to the Exchange Date. With respect to any
Exchange Date Holder presenting more than one Note for exchange, the number of full shares of M&T
Common Stock shall be computed on the basis of the aggregate number of the Notes presented for
exchange by such Exchange Date Holder. The Company shall deliver or cause to be delivered to the
Trustee by 9:30 a.m. (New York City time) on the Exchange Date sufficient funds to permit the
Trustee to make all cash payments required by Section 3.03 and this Section 3.06, and the Trustee
shall not be required to sell shares of M&T Common Stock to make such payments. Such funds shall
be accompanied by a notice from the Company specifying the aggregate amount of cash to be paid in
lieu of fractional shares of M&T Common Stock, including the cash amount per Note. The Trustee
shall have no responsibility for determining the aggregate amount of such cash or the amount of
such cash per Note.

     The “Closing Sale Price” of M&T Common Stock on any Trading Day shall be determined by the
Company and means the per share price of M&T Common Stock on such Trading Day:

19

 

     (i) determined on the basis of the closing per share sale price (or, if no
closing per share sale price is reported, the average of the bid and ask prices or, if
more than one in either case, the average of the average bid and the average ask prices)
on such Trading Day on the principal U.S. national or regional securities exchange on
which shares of M&T Common Stock are listed; or

     (ii) if shares of M&T Common Stock are not listed on a U.S. national or regional
securities exchange, as reported on such Trading Day by Pink OTC Markets Inc. or a similar
organization,

provided that the Closing Sale Price shall be determined without regard to after-hours trading or
extended market making; provided further, that, in the event M&T Common Stock is not so listed or
reported on the applicable Trading Day, the Closing Sale Price shall be the market value of M&T
Common Stock on the applicable Trading Day as determined by the Company in good faith.

     (b) For the avoidance of doubt, any reference in the Indenture to the delivery of M&T Common
Stock by the Company and the Exchange Date Holders’ rights to receive M&T Common Stock in
connection with the mandatory exchange of the Notes on the Exchange Date shall be deemed to include
any cash delivered in lieu of any fractional shares of M&T Common Stock pursuant to this Section
3.06.

     Section 3.07. Limited Rights With Respect to M&T Common Stock. If (i) the Exchange Condition
is not satisfied or (ii) the Exchange Condition is satisfied but the Company fails to deliver the
aggregate number of shares of M&T Common Stock required to exchange all of the Outstanding Notes on
the Exchange Date due to the occurrence of a Regulatory Event, Holders of the Notes hereby
acknowledge that they shall have no rights with respect to the Company’s shares of M&T Common Stock
or any dividend or other distribution declared in connection with such M&T Common Stock other than
the right to receive any Cash M&T Distribution Adjustment. If the Notes are exchanged for M&T
Common Stock pursuant to Section 3.02, Holders of the Notes shall have no rights with respect to
the Company’s shares of M&T Common Stock until the consummation of the mandatory exchange on the
Exchange Date.

ARTICLE 4

Adjustments and M&T Distribution Adjustment

     Section 4.01. Dilution Events; Adjustment of Exchange Ratio. (a) The Exchange Ratio shall be
adjusted by the Trustee upon the occurrence of a Dilution Event with an effective date after the
Pricing Date and prior to the Exchange Date

20

 

or the Maturity Date, as applicable. Once such Dilution Event becomes effective, the Exchange
Ratio shall be adjusted based on the following formula:

ER'=ER0 x Share Ratio

where,

	 	 	 	 	 	 	 

	 

	 	ER0
	 	=
	 	the Exchange Ratio in effect immediately prior to the open of business on
the effective date of such Dilution Event;
	 
	 	 	 	 	 	 
	 

	 	ER'
	 	=
	 	the Exchange Ratio in effect immediately after the open of business on
the effective date of such Dilution Event; and
	 
	 	 	 	 	 	 
	 

	 	Share Ratio
	 	=
	 	the ratio of (x) the number of shares of M&T Common Stock
outstanding immediately after such Dilution Event to (y) the number of shares of M&T
Common Stock outstanding immediately prior to the open of business on the effective
date of such Dilution Event.

     Any adjustment to the Exchange Ratio made under this Section 4.01(a) shall become effective
immediately after the open of business on the effective date of such Dilution Event.

     (b) The Trustee shall provide the Company, no later than the Business Day after its receipt of
the notice from the Company specified in the second sentence of clause (c) below, a written
statement setting out in reasonable detail the calculation of the revised Exchange Ratio. All
determinations made by the Trustee with respect to the revised Exchange Ratio shall, in the absence
of manifest error, be conclusive for all purposes and binding on the Holders of the Notes, the
Trustee, the Paying Agent and the Company.

     (c) Within two Business Days of an announcement by M&T of a Dilution Event, the Company shall
provide written notice to the Holders of the Notes and the Trustee notifying them of the Dilution
Event and the proposed effective date of such Dilution Event. The Company shall give the Trustee
written notice no later than 6:00 p.m. (New York City time) on the effective date of a Dilution
Event of the nature of such event, the effective date thereof and the ratio of (x) the number of
shares of M&T Common Stock outstanding immediately after such Dilution Event to (y) the number of
shares of M&T Common Stock outstanding immediately prior to the open of business on the effective
date of such Dilution Event. The Trustee shall be entitled to conclusively rely on such notice as
to the truth and correctness of all information contained therein.

21

 

     Section 4.02. Cash M&T Distribution Adjustment and Non-cash M&T Distribution Adjustment. (a)
If M&T has declared a Qualifying Distribution and (i) if such Qualifying Distribution includes
cash, the Record Date Holders (which may be different from the Exchange Date Holders that receive
M&T Common Stock in exchange for the Notes on the Exchange Date or the Holders of the Notes that
receive the applicable Redemption Price of the Notes on the Maturity Date) shall receive a Cash M&T
Distribution Adjustment and/or (ii) if such Qualifying Distribution includes non-cash property,
including shares of capital stock, securities or other property, and if the Notes are exchanged for
M&T Common Stock pursuant to Section 3.02, the Exchange Date Holders shall receive a Non-cash M&T
Distribution Adjustment, in each case pursuant to this Section 4.02.

     The Company shall provide written notice to the Trustee of any future record date for any Cash
M&T Distribution Adjustment or Non-cash M&T Distribution Adjustment and the amount of cash and/or
other property to be distributed in any Qualifying Distribution per share of M&T Common Stock no
later than one Business Day after M&T publicly announces the record date and other relevant
information with respect to such Qualifying Distribution.

     For the avoidance of doubt, the Company shall be obligated to make (i) any Cash M&T
Distribution Adjustment when due notwithstanding the prior (a) exchange of the Notes for M&T Common
Stock or the prior redemption of the Notes for their applicable Redemption Price, as applicable,
and (b) release and return of cash held in the Control Account in connection with such Cash M&T
Distribution Adjustment from the Control Account to the Company on the relevant Collateral Release
Date and (ii) any Non-cash M&T Distribution Adjustment if and only if the Notes are exchanged for
M&T Common Stock.

     (b) A Cash M&T Distribution Adjustment shall consist of an amount of cash per Note determined
by the Company equal to the Exchange Ratio (as of the record date of the relevant Qualifying
Distribution) multiplied by the amount of cash paid by M&T per share of M&T Common Stock (without
any deductions for withholding or other Taxes) in connection with such Qualifying Distribution.
Such Cash M&T Distribution Adjustment shall be paid to the relevant Record Date Holders by 9:30
a.m. (New York City time) (or as soon thereafter as is reasonably practicable) on the later of (i)
the Exchange Date or the Maturity Date, as applicable, and (ii) the Business Day immediately
following the Company’s receipt of such Qualifying Distribution.

     (c) A Non-cash M&T Distribution Adjustment shall consist of an amount of such non-cash
property per Note determined by the Company equal to the Exchange Ratio (as of the record date of
the relevant Qualifying Distribution) multiplied by the amount of non-cash property delivered by
M&T per share of M&T Common Stock (without any deductions for withholding or other Taxes) in

22

 

connection with such Qualifying Distribution. If the Notes are exchanged for M&T Common Stock
pursuant to Section 3.02, such Non-cash M&T Distribution Adjustment (together with cash in lieu of
any fractional non-cash property pursuant to Section 4.02(f)) shall be made to the Exchange Date
Holders by 9:30 a.m. (New York City time) (or as soon thereafter as is reasonably practicable) on
the later of (i) the Exchange Date and (ii) the Business Day immediately following the Company’s
receipt of such Qualifying Distribution.

     (d) Upon the receipt by the Company of a Qualifying Distribution from M&T giving rise to a
Cash M&T Distribution Adjustment or a Non-cash M&T Distribution Adjustment, the Company shall
provide written notice to the Trustee by the close of business on the date of receipt of such
Qualifying Distribution notifying the Trustee (i) that the Company has received such Qualifying
Distribution relating to a Cash M&T Distribution Adjustment or a Non-cash M&T Distribution
Adjustment from M&T, (ii) if such Qualifying Distribution includes cash, whether such Qualifying
Distribution was received on or prior to the applicable Delayed Payment Date, (iii) the amount of
such Qualifying Distribution paid and/or delivered by M&T per share of M&T Common Stock (without
any deductions for withholding or other Taxes) and to be delivered to the Trustee or the Paying
Agent for payment or transfer to the Record Date Holders or the Exchange Date Holders, as
applicable (including the aggregate amount and the amount per Note to be so paid or transferred),
and the amount of cash (both the aggregate cash amount and the cash amount per Note) from the
Control Account to be delivered in respect of Cash M&T Distribution Adjustments, as applicable, and
(iv) the Market Price with respect to any cash to be delivered in lieu of fractional property.

     (e) No accrued interest shall be paid to the Record Date Holders or the Exchange Date Holders
with respect to any Cash M&T Distribution Adjustment or Non-cash M&T Distribution Adjustment.

     (f) The Company shall deliver cash in lieu of delivering any fractional non-cash property that
an Exchange Date Holder is entitled to receive in connection with a Non-cash M&T Distribution
Adjustment consisting of shares of capital stock, securities or other non-cash property pursuant to
this Section 4.02. With respect to any Exchange Date Holder that holds more than one Note, the
amount of non-cash property shall be computed on the basis of the aggregate number of Notes held by
such Exchange Date Holder. For purposes of determining the amount of cash to be so delivered with
respect to any such capital stock or other securities that are listed on a U.S. national or
regional securities exchange, the Company shall deliver cash in lieu of any fractional securities
based on the Market Price of the applicable securities on the Business Day (or if such Business Day
is not a Trading Day, on the Trading Day next preceding such Business Day) that the Company
receives the applicable Qualifying Distribution.

23

 

     For the avoidance of doubt, any reference in the Indenture to the delivery of shares of
capital stock, securities or other non-cash property by the Company and the Exchange Date Holders’
rights to receive such shares of capital stock, securities or other non-cash property, in
connection with a Non-cash M&T Distribution Adjustment shall be deemed to include any cash
delivered in lieu of any such fractional non-cash property. Any cash in lieu of fractional non-cash
property shall be delivered to Exchange Date Holders on the later of (i) the Exchange Date and (ii)
the Business Day immediately following the Company’s receipt of such Qualifying Distribution from
M&T.

     The “Market Price” on any Trading Day shall be determined by the Company and means the price
per security on such Trading Day:

     (i) determined on the basis of the closing sale price of such security (or
if no closing sale price is reported, the average of the bid and ask prices or, if there
is more than one in either case, the average of the average bid and the average ask
prices) on such Trading Day on the principal U.S. national or regional securities exchange
on which the applicable securities are listed; or

     (ii) if the applicable securities are not listed on a U.S. national or
regional securities exchange, the closing sale price of such security as reported on such
Trading Day by Pink OTC Markets Inc. or a similar organization,

provided that the closing sale price will be determined without regard to after-hours trading or
extended market making.

     In the event that the applicable securities are not so listed or reported on the applicable
Trading Day, or in the event that the Qualifying Distribution consists of other non-cash property,
the amount of cash to be delivered in lieu of any fractional non-cash property shall be determined
based on the value of the applicable capital stock, securities or other non-cash property on the
Business Day that the Company receives such Qualifying Distribution from M&T as determined by the
Company in good faith.

     Section 4.03. Delivery of any Cash M&T Distribution Adjustment. (a) If a Qualifying
Distribution that includes cash is received by the Company on or prior to the Delayed Payment Date
related to such Qualifying Distribution, the Company shall direct the Trustee (such direction to be
contained in the notice delivered pursuant to Section 4.02(d)) to pay from the Control Account to
the Trustee or the Paying Agent through DTC, for the benefit of the Record Date Holders, by 9:30
a.m. (New York City time) (or as soon thereafter as is reasonably practicable) on the date such
Cash M&T Distribution Adjustment becomes due, the amount of cash then due in connection with such
Cash M&T

24

 

Distribution Adjustment pursuant to Section 4.02, credited to an account at DTC in the name of
the Trustee (or its nominee) or the Paying Agent for the benefit of the Record Date Holders.

     (b) If (i) the amount of cash due in connection with a Cash M&T Distribution Adjustment
described in clause (a) above exceeds the amount of cash in the Control Account available for
payment to Record Date Holders or (ii) if a Qualifying Distribution that includes cash was received
by the Company after the Delayed Payment Date related to such Qualifying Distribution, in each case
the Company shall deliver an amount of cash equal to such excess for purposes of clause (i) above
or the amount of cash then due in connection with such Cash M&T Distribution Adjustment for
purposes of clause (ii) above, as applicable, pursuant to Section 4.02 by wire transfer of
immediately available funds to an account designated by the Trustee or the Paying Agent, for the
benefit of the Record Date Holders, credited to an account at DTC in the name of the Trustee (or
its nominee) or the Paying Agent for the benefit of the Record Date Holders by 9:30 a.m. (New York
City time) (or as soon thereafter as is reasonably practicable) on the date such M&T Distribution
Adjustment becomes due.

     (c) Subject to the foregoing, upon receipt of transfer instructions from the relevant Record
Date Holders (or, in the absence of instructions from the relevant Record Date Holders, pursuant to
standing instructions provided by such Record Date Holders), the Trustee or the Paying Agent shall
transfer any Cash M&T Distribution Adjustment that such Record Date Holders are entitled to
receive, but without any interest thereon, to such Record Date Holder by wire transfer, or other
appropriate procedures, in accordance with such instructions.

     Section 4.04. Delivery of any Non-cash M&T Distribution Adjustment. (a) In connection with a
Non-cash M&T Distribution Adjustment, the Company shall deliver the amount of non-cash property
(and any cash in lieu of fractional non-cash property pursuant to Section 4.02(f)) then due in
connection with such Non-cash M&T Distribution Adjustment pursuant to Section 4.02 by delivery to
the Trustee or the Paying Agent, for the benefit of the Exchange Date Holders, credited to an
account at DTC in the name of the Trustee (or its nominee) or the Paying Agent for the benefit of
the Exchange Date Holders by 9:30 a.m. (New York City time) on the date such Non-cash M&T
Distribution Adjustment becomes due. Cash in lieu of fractional non-cash property delivered
pursuant to this Section 4.04 shall be accompanied by a notice from the Company specifying the
aggregate amount of cash to be paid in lieu of fractional non-cash property including the cash
amount per Note. The Trustee shall have no responsibility for determining the aggregate amount of
such cash or the amount of such cash per Note.

25

 

     (b) Any non-cash property delivered by the Trustee or the Paying Agent in connection with a
Non-cash M&T Distribution Adjustment shall be registered, if applicable, in the name of the
Exchange Date Holder or, if so specified in any instructions provided by such Exchange Date Holder
to the Trustee or Paying Agent, in the name of a designee.

of M&T Common Stock pursuant to Section 3.06) in connection with a mandatory exchange of the Notes
when due on the Exchange Date; or

     (c) failure to make any Cash M&T Distribution Adjustment or Non-cash M&T Distribution

indemnity against the costs, expenses and liabilities which might be incurred by it in compliance
with such request, and provided, that compliance with such request shall not be in conflict with
any rule of law or with the Indenture or would not be unjustly prejudicial to the Holders of any
Notes (or Record Date Holders or Exchange Date Holders, as applicable) not taking part in the
request, as determined by the Trustee and subject to the right of the Trustee to take any action
deemed proper by the Trustee, and not inconsistent with such request, proceed to protect and
enforce its rights and the rights of the Holders of the Notes and/or the Record Date Holders, as
applicable, by such appropriate judicial proceedings as the Trustee shall deem most effectual to
protect and enforce any such rights, whether for the specific enforcement of any covenant or
agreement in the Indenture or in aid of the exercise of any power granted herein, or to enforce any
other proper remedy, including the institution of proceedings in Ireland (but not elsewhere) for

the Notes, or for any claim based thereon and no recourse under or upon any obligation, covenant or
agreement of the Company in the Indenture, or in any Note, or because of the creation of any
indebtedness represented thereby, shall be had against any incorporator, stockholder, officer or
director, past, present or future, of the Company or of any successor corporation of the Company,
either directly or through the Company or any successor corporation of the Company, whether by
virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or

notice to the Trustee of a continuing Event of Default with respect to the Notes specifying such
Event of Default and stating that such notice is a “Notice of Default” hereunder;

     (b) the Holders of at least 25% in aggregate principal amount of the Outstanding Notes (or, if

reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with

M&T Distribution Adjustment, respectively); and

     (f) in the case of a proceeding for the winding-up of the Company in Ireland, such proceeding
is in the name and on behalf of the Trustee to the same extent (but no further or otherwise) as the
Trustee would have been entitled so to do;

it being understood and intended that no one or more Holders of the Notes or one or more Record
Date Holders, as applicable, shall have any right in any manner whatever by virtue of, or by
availing of any provision of the Indenture to affect, disturb or prejudice the rights of any other
such Holders of the Notes or any other such Record Date Holders, as applicable, or to obtain or to
seek to obtain priority or preference over any other such Holders of the Notes or any other such

Adjustment, as applicable, with respect to the Notes on their respective due dates, and to

29

 

suit for the enforcement of any such payment and/or delivery, and such rights shall not be
impaired without the consent of such Holder of Notes or Record Date Holder, as applicable.

Notes.

     Section 5.06. Control By Holders. This Section 5.06 shall replace in its entirety Section
5.12 of the Original Indenture, and all references in the Original Indenture to “Section 5.12”

Indenture, the Holders of a majority in aggregate principal amount of the Outstanding Notes (or, if
on or after the Exchange Date or Maturity Date, as applicable, and with respect to a failure to
make any Cash M&T Distribution Adjustment or Non-cash M&T Distribution Adjustment when due
(including cash in lieu of any fractional non-cash property), Record Date Holders or Exchange Date
Holders entitled to more than 50% of the applicable Cash M&T Distribution Adjustment or Non-cash
M&T Distribution Adjustment, respectively) shall have the right to direct the time, method and
place of conducting any proceeding in the name of and on behalf of the Trustee for any remedy
available to the Trustee, or exercising any trust or power conferred on the Trustee with respect to
the Notes; provided that

     (a) such direction shall not be in conflict with any rule of law or with the Indenture;

     (b) such direction shall not be unjustly prejudicial to the Holders of Notes or Record Date
Holders, as applicable, not taking part in the direction, as determined by the Trustee; and

     (c) the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction.

     Section 5.07. Waiver of Past Events of Default. This Section 5.07 shall replace in its

“Section 5.13” shall be deemed a reference to this Section 5.07. The Holders of a majority of the
aggregate principal amount of the Outstanding Notes may, on behalf of the Holders of all
Outstanding Notes, waive any past Event of Default, except that the consent of each Holder of a
Note affected thereby (or, if on or after the Exchange Date or Maturity Date, as applicable, and
with respect to a failure to make any Cash M&T Distribution Adjustment or Non-cash M&T Distribution
Adjustment when due (including cash in lieu of any fractional non-cash property), each Record Date
Holder or

30

 

Exchange Date Holder affected thereby) is required to waive any Event of Default in respect
of:

     (a) the Company’s failure to pay the applicable Redemption Price when due on the Maturity
Date;

     (b) the Company’s failure to make any Cash M&T Distribution Adjustment or Non-cash M&T
Distribution Adjustment (including cash in lieu of any fractional non-cash property) when due;

     (c) if the Exchange Condition has been satisfied, the Company’s failure to deliver the
aggregate number of shares of M&T Common Stock required to exchange all of the Outstanding Notes on
the Exchange Date (including cash in lieu of any fractional shares of M&T Common Stock), unless
such failure is due to the occurrence of a Regulatory Event; or

     (d) a covenant or provision of the Indenture which under Article IX of the Original Indenture
and Article 6 of this First Supplemental Indenture cannot be modified or amended without the
consent of each Holder of Notes or Record Date Holder, as applicable.

     Section 5.08. Undertaking For Costs. This Section 5.08 shall replace in its entirety Section
5.14 of the Original Indenture, and all references in the Original Indenture to “Section 5.14”
shall be deemed a reference to this Section 5.08. All parties to the Indenture agree, and each
Holder of Notes and each Record Date Holder, as applicable, by his or her acceptance thereof shall
be deemed to have agreed, that any court may in its discretion require, in any suit for the
enforcement of any right or remedy under the Indenture, or in any suit against the Trustee for any
action taken, suffered or omitted by it as Trustee, the filing by any party litigant to such suit
of an undertaking to pay the costs of such suit, and that such court may in its discretion assess
reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by such party
litigant; but the provisions of this Section 5.08 shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Holder of the Notes or Record Date Holder, as applicable, or
group of Holders of the Notes or Record Date Holders, as applicable, holding in the aggregate more
than 10% in principal amount of the Outstanding Notes (or, if on or after the Exchange Date or
Maturity Date, as applicable, and with respect to any Cash M&T Distribution Adjustment or Non-cash
M&T Distribution Adjustment, Record Date Holders or Exchange Date Holders entitled to more than 10%
of the applicable Cash M&T Distribution Adjustment or Non-cash M&T Distribution Adjustment,

Holders and Record Date Holders from time to time of the Notes that it will not, prior to the

33

 

     Section 7.05. Charges and Taxes. Notwithstanding anything to the contrary in the Indenture,

     Section 7.09. Additional Amounts. This Section 7.09 shall replace in its entirety Section
10.4 of the Original Indenture, and all references in the Original Indenture to “Section 10.4”
shall be deemed a reference to this Section 7.09. Any amounts (including capital stock or other
non-cash property) to be paid and/or delivered by the Company with respect to the Notes (the
“Original Amount”) will be paid without deduction or withholding for, or on account of, any and all
present or future taxes, duties, assessments or other governmental charges (“Taxes”) now or
hereafter imposed, levied, collected, withheld or assessed by or

34

 

on behalf of Ireland (the “Taxing Jurisdiction”), unless such deduction or withholding is
required by law. If any such Taxes shall at any time be required by the Taxing Jurisdiction to be
deducted or withheld, the Company will pay such additional amounts of, or in respect of, the
Original Amount (“Additional Amounts”) as may be necessary in order that the net amounts paid to
the Holders of the Notes or the Record Date Holders, as applicable, after such deduction or
withholding, shall equal such Original Amount, had no such deduction or withholding been required;
provided that the foregoing will not apply to any such Taxes that would not have been payable or
due but for the fact that (i) the Holder or the Beneficial Owner of the Notes or the Record Date
Holder, as applicable, is a domiciliary, national or resident of, or engages in business or
maintains a permanent establishment or is physically present in, the Taxing Jurisdiction requiring
such deduction or withholding of Taxes, or otherwise has some connection with the Taxing
Jurisdiction other than the holding or ownership of the Notes, or the collection of the Original
Amount, (ii) except in the case of a winding-up of the Company in Ireland the Notes are presented
for payment and/or exchange in Ireland, (iii) the relevant Notes are presented for payment and/or
delivery more than thirty (30) days after the date payment and/or delivery became due or was
provided for, whichever is later, except to the extent that the Holder of the Notes or the Record
Date Holder, as applicable, would have been entitled to such Additional Amounts on presenting the
same for payment and/or delivery at the close of such 30-day period, (iv) the Holder or the
Beneficial Owner of the Notes or the Record Date Holder, as applicable, or the Beneficial Owner of
any payment and/or delivery of the Original Amount failed to make any necessary claim or to comply
with any certification, identification or other requirements concerning the nationality, residence,
identity or connection with the taxing jurisdiction of such Holder or Beneficial Owner of the Notes
or Record Date Holder, as applicable, if such claim or compliance is required by statute, treaty,
regulation or administrative practice of the Taxing Jurisdiction as a condition to relief or
exemption from such Taxes, (v) such Taxes are imposed on a payment to an individual and are
required to be made pursuant to the Directive on the Taxation of Savings 2003/48/EC (the
“Directive”) adopted by the Council of the European Union on June 3, 2003, or any law implementing
or complying with, or introduced in order to conform to, such Directive, (vi) the Notes are
presented for payment or exchange by or on behalf of a Holder who would have been able to avoid
such Taxes by presenting or exchanging the relevant Notes to another Paying Agent in a member state
of the European Union or elsewhere or (vii) if such Taxes would not have been so imposed, or would
have been excluded pursuant to clauses (i) through (vi) above inclusive, if the Beneficial Owner
of, or person ultimately entitled to obtain an interest in, such Notes had been the Holder of such
Notes. Whenever in the Indenture there is mentioned, in any context, the payment and/or delivery of
the Original Amount, on or in respect of any Note, such mention shall be deemed to include mention
of the payment of Additional Amounts provided for in this Section to the extent that, in such
context,

35

 

Additional Amounts are, were or would be payable in respect thereof pursuant to the provisions
of this Section and as if express mention of the payment of Additional Amounts (if applicable) were
made in any provisions hereof where such express mention is not made.

     Section 7.10. Treatment of the Notes for United States Federal Income Tax Purposes. The
Company and each Holder of the Notes (and any successor Holder of, or Beneficial Owner of, the
Notes), by its respective purchase of the Notes, agree (in the absence of an administrative
determination or judicial ruling to the contrary) to characterize the Notes for all tax purposes as
a forward purchase contract to purchase shares of M&T Common Stock on the Exchange Date, coupled
with a deposit of a fixed amount of cash, equal to the issue price, to secure the Holder’s
obligation under the forward purchase contract.

ARTICLE 8

The Trustee

     Section 8.01. Compensation and Reimbursement. Section 6.8 of the Original Indenture shall be
amended by replacing the last sentence thereof with the following:

     “As security for the performance of the obligations of the Company under this Section, the
Trustee shall have a lien upon all amounts held in the Control Account, which obligations shall be
payable out of the Collateral only to the extent of Collateral in excess of all amounts payable to
or for the benefit of the Holders of the Notes and the Record Date Holders pursuant to the terms of
the Indenture.”

     Section 8.02. Calculations. Notwithstanding anything herein to the contrary, the Trustee
shall not be responsible for calculating the Redemption Price (including the amount of any
reduction therefrom), the number of shares of M&T Common Stock exchangeable per Note on the
Exchange Date, the aggregate amount of cash payable in lieu of fractional shares of M&T Common
Stock per Note or the aggregate amount of cash payable in lieu of fractional non-cash property in
connection with a Non-cash M&T Distribution Adjustment per Note, all of which determinations shall
be made by the Company.

ARTICLE 9

Satisfaction And Discharge

     Section 9.01. Satisfaction and Discharge of Indenture. This Section 9.01 shall replace in
its entirety Article IV of the Original Indenture. The Indenture

36

 

shall upon Company Request cease to be of further effect with respect to the Notes (except as
to any surviving rights of registration of transfer, redemption or exchange of the Notes expressly
provided for) and the Trustee, at the expense of the Company, shall execute proper instruments
acknowledging satisfaction and discharge of the Indenture with respect to the Notes when:

     (a) all Notes theretofore authenticated and delivered (other than (x) Notes that have been
destroyed, lost or stolen and that have been replaced or paid as provided in Section 3.6 of the
Original Indenture and (y) Notes for which the applicable Redemption Price has theretofore been
deposited in trust and segregated and held in trust and thereafter returned to the Company as
provided in Section 2.05) have been delivered to the Trustee for cancellation;

     (b) the Company has paid and/or delivered or caused to be paid and/or delivered all other
amounts or property payable and/or deliverable hereunder by the Company with respect to the Notes;
and

     (c) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of
Counsel, each stating that all conditions precedent herein provided for relating to the
satisfaction and discharge of the Indenture with respect to the Notes have been complied with.

     Notwithstanding any satisfaction and discharge of the Indenture with respect to the Notes, the
obligations of the Company to the Trustee under Section 6.8 of the Original Indenture as amended by
Section 8.01 of this First Supplemental Indenture and the obligations of the Trustee to any
Authenticating Agent under Section 6.15 of the Original Indenture shall survive.

account at DTC in the name of the Trustee (or its nominee) or the Paying Agent for the benefit of
the Record Date Holders or Exchange Date Holders, as applicable, in accordance with DTC’s
procedures. Subject to compliance with the applicable conditions set forth in the Indenture, upon
book-entry transfer of the Notes or delivery of the Notes to the Trustee with appropriate and duly
completed instructions on the Exchange Date (in connection with a mandatory exchange of the Notes)
or the Maturity Date (in connection with a redemption of the Notes), the Trustee shall authorize
the delivery through DTC of the shares of M&T Common Stock or pay the Redemption Price, as
applicable, but without any interest thereon, to the Holder hereof by wire transfer (in connection
with a redemption of the Notes) or book-entry transfer (in connection with a mandatory exchange of
the Notes), or other appropriate procedures, in accordance with such instructions. The Company
will pay, in money of the United States that at the time of payment is legal tender for payment of
public and private debts, all amounts payable in cash with respect to the Notes.

     4. Indenture. The Company issued the Notes under a Senior Debt Securities Indenture dated as
of June 2, 2008 (the “Original Indenture”), as supplemented by the First Supplemental Indenture
dated as of October 13, 2010 (the “First Supplemental Indenture” and the Original Indenture, as
supplemented by the First Supplemental Indenture, the “Indenture”) between the Company and The Bank
of New York Mellon, as trustee (the “Trustee”). The Bank of New York Mellon shall also be the
initial Paying Agent. The terms of the Notes include those stated in the Indenture and those made
part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code §§
77aaa-77bbbb) (the “TIA”) as amended and in effect from time to time. The Notes are one of a

be exchanged, with respect to each Note, for a number of shares of M&T Common Stock equal to the
Exchange Ratio.

“Qualifying Distribution”) and (i) if such Qualifying Distribution includes cash, the record
Holders of Notes as of the close of business on the record date for such Qualifying Distribution
(the “Record Date Holders”) shall receive a Cash M&T Distribution Adjustment and/or (ii) if such
Qualifying Distribution includes non-cash property, including shares of capital stock, securities
or other property, and if the Notes are exchanged for M&T Common Stock, the Exchange Date Holders

the Company shall pledge an amount of cash equal to 101% of the aggregate principal amount of the
Notes to secure all cash payments the Company is required to make, whether in connection with the
redemption of the Notes, if applicable, or any Cash M&T Distribution Adjustment, if applicable.

     9. Denominations, Transfer, Exchange. The Notes shall be issued only in registered form
without coupons in denominations of $77.50 and any integral multiples thereof. The transfer of
Notes may be registered and Notes may be exchanged or redeemed as provided in the Indenture. The
Company shall pay all documentary, stamp or similar transfer tax due on the registration, exchange
or transfer of the Notes, the shares of M&T Common Stock, any Cash M&T Distribution Adjustment or
any Non-cash M&T Distribution Adjustment, as applicable, pursuant to the terms of the Notes, the
Indenture and the Security Agreement.

     10. Amendments and Supplements. The Indenture contains provisions permitting the Company and
the Trustee in certain circumstances, without the consent of the Holders of the Notes or the Record
Date Holders, as applicable, and in other circumstances, with the consent of the Holders of the
Notes or Record Date Holders, as applicable, as in the Indenture provided, to enter into a
supplemental indenture to amend or supplement the terms of the Indenture and the Notes as described
therein.

     11. Defaults and Remedies; Waivers. In case an Event of Default with respect to the Notes
specified in Section 5.01 of the First Supplemental Indenture occurs and is continuing, the Trustee
(i) may in its discretion or (ii) shall, at the request of Holders of at least 25% in aggregate
principal amount of the Outstanding Notes (or, if on or after the Exchange Date or Maturity Date,
as applicable, and with respect to a failure to make any Cash M&T Distribution Adjustment or
Non-cash M&T Distribution Adjustment when due, at the request of Record Date Holders or Exchange
Date Holders entitled to at least 25% of the applicable Cash M&T Distribution Adjustment or
Non-cash M&T Distribution Adjustment, respectively) and after such Holders of Notes (or Record Date
Holders or Exchange Date Holders, as applicable) provide the Trustee with satisfactory indemnity
against the costs, expenses and liabilities which might be incurred by it in compliance with such
request, and provided, that compliance with such request shall not be in conflict with any rule of
law or with the Indenture or would not be unjustly prejudicial to the Holders of any Notes (or
Record Date Holders or Exchange Date Holders, as applicable) not taking part in the request, as
determined by the Trustee and subject to the right of the Trustee to take any action deemed proper
by the Trustee, and not inconsistent with such

6

 

request, proceed to protect and enforce its rights and the rights of the Holders of the Notes
or Record Date Holders, as applicable, by such appropriate judicial proceedings as the Trustee
shall deem most effectual to protect and enforce any such rights.

Subject to Section 5.06 of the First Supplemental Indenture, the Holders of a majority in aggregate
principal amount of the Outstanding Notes (or, if on or after the Exchange Date or Maturity Date,
as applicable, and with respect to a failure to make any Cash M&T Distribution Adjustment or
Non-cash M&T Distribution Adjustment when due, Record Date Holders or Exchange Date Holders
entitled to more than 50% of the applicable Cash M&T Distribution Adjustment or Non-cash M&T
Distribution Adjustment, respectively) shall have the right to direct the time, method and place of
conducting any proceeding in the name of and on the behalf of the Trustee for any remedy available
to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Notes;
provided, however, that this direction must not be in conflict with any rule of law or the
Indenture, and must not be unjustly prejudicial to the Holder of Notes or Record Date Holders, as
applicable, not taking part in the direction, as determined by the Trustee.

It is also provided in the Indenture that, subject to certain exceptions, without the consent of
each affected Holder of the Notes (or, if on or after the Exchange Date or Maturity Date, as
applicable, and with respect to a failure to make any Cash M&T Distribution Adjustment or Non-cash
M&T Distribution Adjustment when due, without the consent of each affected Record Date Holder or
Exchange Date Holder, respectively) certain modifications or waivers of existing defaults cannot be
made.

     12. Treatment of the Notes for United States Federal Income Tax Purposes. The Company and
each Holder of the Notes (and any successor Holder of, or Beneficial Owner of, the Notes), by its
respective purchase of the Notes, agree (in the absence of an administrative determination or
judicial ruling to the contrary) to characterize the Notes for all tax purposes as a forward
purchase contract to purchase shares of M&T Common Stock on the Exchange Date, coupled with a
deposit of a fixed amount of cash, equal to the issue price, to secure the Holder’s obligation
under the forward purchase contract.

     13. Authentication. This Note shall not be valid until authenticated by the manual signature
of the Trustee or an authenticating agent in accordance with the Indenture.

     14. Abbreviations. Customary abbreviations may be used in the name of a Holder of the Note or
an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entirety), JT TEN (=
joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and
U/G/M/A (Uniform Gifts to Minors Act).
