ARTICLE IV

CALCULATION OF SUPPLEMENTAL PENSION BENEFIT; VESTING

	 	4.1	 	Calculation of Supplemental Pension Benefit.

	 	(a)	 	The amount of the Supplemental Pension Benefit to which a Participant is
entitled hereunder shall be the result obtained by subtracting (ii) from (i), where:

	 	(i)	 	equals the annual benefit (or the lump sum Actuarial Equivalent
thereof) that would have been payable to the Participant under the Pension
Plan, as of the Participant’s Benefit Commencement Date assuming that (A) the
Participant elected to have his accrued benefit under the Pension Plan paid in
the same form of payment elected by the Participant under Article V hereof, (B)
such accrued benefit was not limited by the Compensation Limitation, and (C)
such accrued benefit was calculated using the Participant’s Compensation, as
defined herein but capped at (I) $235,840, for calendar years beginning on and
after January 1, 1994, but before January 1, 2006, and (II) $350,000, for
calendar years beginning on and after January 1, 2006, rather than the
Participant’s compensation, as defined in the Pension Plan; and

	 	(ii)	 	equals the annual benefit (or the lump sum Actuarial Equivalent
thereof) that would have been payable to the Participant under the Pension
Plan, as of the Participant’s Benefit Commencement Date, assuming that the
Participant elected to have his accrued benefit thereunder paid in the form of
payment elected by the Participant under Article V hereof.

	 	(b)	 	The Supplemental Pension Benefit payable with respect to a Participant shall be
calculated with the objective that the total amount that the Participant (and his
Beneficiary, if any) should receive under this Supplemental Pension Plan and the
Pension Plan should equal the total amount that would otherwise have been payable to
the Participant (and his Beneficiary, if any) solely under the Pension Plan, as of the
Participant’s Benefit Commencement Date assuming that the Participant’s accrued benefit
thereunder was calculated and paid in accordance with (a)(i) above.

	 	4.2	 	Calculation of Supplemental Death Benefit.

	 	(a)	 	If a Participant who is vested in his Supplemental Pension Benefit dies prior
to the payment or commencement of payment thereof, the Participant’s Surviving Spouse
shall receive a Supplemental Death Benefit commencing on the Surviving Spouse’s Benefit
Commencement Date. The amount of the Supplemental Death Benefit to which a Surviving
Spouse is entitled shall be the result obtained by subtracting (ii) from (i), where:

	 	(i)	 	equals the annual preretirement survivor benefit that would
have been payable to the Surviving Spouse under the Pension Plan, as of the
Surviving Spouse’s Benefit Commencement Date in the form of a Preretirement
Survivor Annuity assuming that (A) the Participant’s accrued benefit under the
Pension Plan was not limited by the Compensation Limitation, and (B) such
accrued benefit was calculated using the Participant’s Compensation, as defined
herein and capped in the manner set forth in Section 4.1(a)(i) hereof, rather
than the Participant’s compensation, as defined in the Pension Plan; and

	 	(ii)	 	equals the annual preretirement survivor benefit that would
have been payable to the Surviving Spouse under the Pension Plan as of the
Surviving Spouse’s Benefit Commencement Date in the form of a Preretirement
Survivor Annuity.

	 	(b)	 	The Supplemental Death Benefit payable with respect to a Participant’s
Surviving Spouse shall be calculated with the objective that the total amount the
Surviving Spouse should receive under this Supplemental Pension Plan and the Pension
Plan should equal the total amount that would otherwise have been payable to the
Surviving Spouse solely under the Pension Plan, as of the Surviving Spouse’s Benefit
Commencement Date assuming that the Surviving Spouse’s preretirement survivor benefit
thereunder was calculated and paid in accordance with (a) above.

	 	(c)	 	Notwithstanding any other provision of the Plan, no Supplemental Death Benefit
shall be payable with respect to a Participant who, on the date of the Participant’s
death, is not vested in his Supplemental Pension Benefit or has no Surviving Spouse.

	 	4.3	 	No Duplication of Benefits. Notwithstanding any provision of this Supplemental
Pension Plan to the contrary, the Supplemental Pension Benefits provided under this Article IV
shall be determined and coordinated by the Committee so as to prevent any duplication of
benefits under this Plan and the Pension Plan or under any individual employment or
supplemental pension agreement.

	 	4.4	 	Vesting. A Participant’s Supplemental Pension Benefit shall be vested and
nonforfeitable to the same extent (and in the same percentage) as the Participant’s accrued
benefit under the Pension Plan.

ARTICLE V

COMMENCEMENT AND FORM OF BENEFITS

	 	5.1	 	Pre-2007 Benefit Commencement Date and Payment Form. If a Participant begins to
receive pension benefits, or a Surviving Spouse begins to receive preretirement survivor
benefits, under the Pension Plan prior to January 1, 2007, the Benefit Commencement Date of
the Participant’s Supplemental Pension Benefit or the Surviving Spouse’s Supplemental Death
Benefit hereunder shall be the date on which the Participant or Surviving Spouse begins to
receive pension or preretirement survivor benefits under the Pension Plan, and the form of
payment of the Participant’s Supplemental Pension Benefit or the Surviving Spouse’s
Supplemental Death Benefit hereunder shall be the same form of payment as the Participant’s or
Surviving Spouse’s pension or preretirement survivor benefits under the Pension Plan.

	 	5.2	 	Post-2006 Benefit Commencement Date and Payment Form.

	 	(a)	 	If a Participant does not begin to receive pension benefits under the Pension
Plan before January 1, 2007, the Participant’s Supplemental Pension Benefit shall be
paid or begin to be paid in accordance with the Participant’s payment elections under
Section 3.3 hereof.

	 	(b)	 	If a Surviving Spouse does not begin to receive preretirement survivor benefits
under the Pension Plan before January 1, 2007, the Benefit Commencement Date of the
Surviving Spouse’s Supplemental Death Benefit shall be the later of the date (i) on
which the Participant attains Earliest Retirement Age (or would have attained Earliest
Retirement Age assuming that the Participant terminated employment on the date of his
death and survived until such age), or (ii) of the Participant’s death.

	 	(c)	 	A Benefit hereunder shall be paid or begin to be paid on a Participant’s or
Surviving Spouse’s Benefit Commencement Date or as soon as practicable thereafter, but
not later than the later of (i) December 31 of the calendar year in which the Benefit
Commencement Date occurs, or (ii) the 15th day of the third calendar month
following the Benefit Commencement Date.

	 	5.3	 	Mandatory Cashouts. Notwithstanding Section 5.2 hereof and effective January 1,
2007, if the Actuarially Equivalent lump sum value of (a) a Participant’s Supplemental Pension
Benefit as of the date of the Participant’s Separation from Service or Disability, or (b) a
Surviving Spouse’s Supplemental Death Benefit as of the date of the Participant’s death, does
not exceed $25,000, the Participant’s Supplemental Pension Benefit or Surviving Spouse’s
Supplemental Death Benefit shall be paid in a single lump sum cash payment as soon as
practicable after the date of the Participant’s Separation from Service or Disability, but not
later than the later of (i) the 15th day of the third calendar month following the
date of the Participant’s Separation from Service or Disability, as applicable, or (ii)
December 31 of the calendar year in which the Separation from Service or Disability, as
applicable, occurs.

	 	5.4	 	Mandatory Delay in Benefit Payments for Specified Employees. Notwithstanding
Sections 5.2 through 5.3 hereof, to the extent required by Section 409A of the Code, the
Committee shall delay payment of the Supplemental Pension Benefit of a Participant who is a
“specified employee” (as defined below) until the earlier of (a) the date that is six months
after the date of any termination of employment or other event that constitutes the specified
employee’s Separation from Service, or (b) the date of the specified employee’s death. The
aggregate amount of payment(s) otherwise payable during the delay period (plus interest
thereon at the short-term Applicable Federal Rate, provided that such interest does not cause
the Plan to violate Section 409A of the Code) shall be payable to the specified employee as
soon as practicable after the expiration of the delay period. For purposes of this Section
5.5, the term “specified employee” shall have the same meaning as under Section 409A of the
Code.

	 	5.5	 	Discretionary Delay in Benefit Payments. Notwithstanding Sections 5.2 and 5.3
hereof, the Committee may delay payment of a Benefit by reason of any event(s) or condition(s)
permitted under Section 409A of the Code, including without limitation, delays relating to (a)
nondeductible Compensation payments under Section 162(m) of the Code; (b) violations of loan
agreements; and (c) violations of federal securities law or other applicable law.

	 	5.6	 	Payment by Employer. The Supplemental Pension Benefit payable hereunder to, or on
behalf of, a Participant shall be paid by the Employer who last employed the Participant.

The Committee shall have all such powers as may be necessary to discharge its duties relative
to the administration of this Supplemental Pension Plan, including by way of illustration and
not limitation, discretionary authority to interpret and construe this Supplemental Pension
Plan, to decide any dispute arising hereunder, to determine the right of any Employee with
respect to participation herein, to determine the right of any Participant with respect to

regulations and practices governing the operation of this Supplemental Pension Plan as it, in
its sole discretion, may from time to time deem advisable. No member of the Committee shall
be liable to any person for any action taken or omitted in connection with the interpretation
and administration of this Supplemental Pension Plan unless attributable to willful misconduct
or lack of good faith. The Committee shall be entitled to rely conclusively upon all tables,
valuations, certificates, opinions and reports furnished by any actuary, accountant,
controller, counsel or other person employed or engaged by the Committee or the Company with
respect to this Supplemental Pension Plan. A Committee member shall not participate in any
action or determination relating solely to his own Benefit hereunder. Except as provided in
Sections 6.2 and 6.3 hereof, decisions of the Committee made in good faith shall be final,
conclusive and binding upon all parties.

	 	6.2	 	Denial of Claim for Benefits.

	 	(a)	 	Claims for Benefits under the Plan shall be filed with the Committee. If any
Participant or other payee (a “Claimant”) claims to be entitled to a Benefit hereunder
and the Committee determines that such claim should be denied in whole or in part, the
Committee shall notify such Claimant of its decision in writing (which may be provided
electronically). Such notification will be written in a manner calculated to be
understood by the Claimant and will contain (i) specific reasons for the denial, (ii)
specific reference to pertinent Plan provisions, (iii) a description of any additional
material or information necessary for the Claimant to perfect such claim and an
explanation of why such material or information is necessary, and (iv) a description of

502(a) of ERISA following the rendering of an adverse decision on review.

	 	(b)	 	Notification of the denied claim will be given within a reasonable period of
time, but not later than 90 days after the claim is received by the Committee, unless
the Committee determines that special circumstances require an extension of time for
processing the claim. If the Committee determines that such an extension of time is
required, written notice of the extension shall be provided to the Claimant prior to
the end of the initial 90-day period. The extension notice shall indicate the special
circumstances requiring the extension of time and the date by which the Committee
expects to render its decision. In no event shall the extension exceed an additional
90 days from the end of the initial 90-day period. Any electronic notification
provided by the Committee under this Article VI shall comply with the standards imposed
by 29 C.F.R. 2520.104b-1(c)(1)(i)-(iv).

	 	6.3	 	Review Procedures.

	 	(a)	 	Within 60 days after the date on which a Claimant receives a written notice of
a denied claim, the Claimant may file a written request with the Committee for a review
of the denied claim. If the Claimant requests a review of the denied claim, the
Claimant shall be entitled to submit to the Committee written comments, documents,
records and other information relating to the claim for Benefits and to receive, upon
request and free of charge, reasonable access to, and copies of, all documents, records
and other information relevant to the Claimant’s claim for Benefits. The Committee
shall perform its review taking into account all comments, documents, records and other
information submitted by the Claimant relating to the claim without regard to whether
such information was submitted or considered in the initial Benefit determination. The
Committee will notify the Claimant of its decision in writing (which may be provided
electronically). If the claim is denied, the notification will be written in a manner
calculated to be understood by the Claimant and will contain (i) the specific reasons
for the denial, (ii) references to pertinent provisions of the Plan, (iii) a statement

action under Section 502(a) of ERISA.

	 	(b)	 	The review provided for by (a) above will be made within a reasonable period of
time, but not later than 60 days after the Committee receives the request for review,
unless the Committee determines that special circumstances require an extension of time
for processing the claim. If the Committee determines that an extension of time is
required, written notice of the extension shall be furnished to the Claimant prior to
the end of the initial 60-day period. The extension notice shall indicate the special
circumstances requiring the extension of time and the date by which the Committee
expects to render its decision. In no event shall the extension exceed an additional
60 days from the end of the initial 60-day period. If the extension of time is needed
due to the Claimant’s failure to submit information necessary to make a decision, the
period during which the Committee must make a decision shall be tolled from the date
the extension notice is sent to the Claimant until the date the Claimant responds to
the request for additional information.

ARTICLE VII

termination is necessary or desirable. Any such amendment or termination shall be made in
writing by the Board of Directors of the Company or its designee, if applicable, and shall be
effective as of the date specified in such document. No amendment or termination of this
Supplemental Pension Plan shall directly or indirectly reduce the Benefit of any Participant
or Beneficiary as of the effective date of such amendment or termination (assuming, in the
case of a Participant, that the Participant is vested in his Benefit and has a Separation from
Service as of such effective date and survives until his elected Benefit Commencement Date)
without the written consent of the Participant or Beneficiary.

	 	7.2	 	Payment of Benefits upon Termination of Plan. In the event of the termination of the

connection with a “change of control” within the meaning of Section 409A of the Code.

ARTICLE VIII

MISCELLANEOUS

	 	8.1	 	No Effect on Employment Rights. Nothing contained herein will confer upon any
Participant the right to be retained in the service of an Employer nor limit the right of an
Employer to discharge or otherwise deal with Participants without regard to the existence of
this Supplemental Pension Plan.

	 	8.2	 	Plan Unfunded. Notwithstanding any provision herein to the contrary, the benefits
offered hereunder shall constitute nothing more than unfunded, unsecured promises by each
Employer to pay the benefits determined hereunder that such Employer is obligated to pay under
Section 5.6 hereof. No provision shall at any time be made with respect to segregating any
assets of any Employer for payment of any Benefits hereunder. No Participant, Beneficiary or
any other person shall have any interest in any particular assets of the Employers by reason
of the right to receive a Benefit hereunder, and any such Participant, Beneficiary or other
person shall have only the rights of a general unsecured creditor of the Employer by whom the
Participant was last employed with respect to any rights under this Supplemental Pension Plan.
Nothing contained in this Supplemental Pension Plan shall constitute a guaranty by the
Employers or any other entity or person that the assets of any Employer will be sufficient to
pay any benefit hereunder. All expenses and fees incurred in the administration of this
Supplemental Pension Plan shall be paid by the Employers.

	 	8.3	 	Binding on Employers, Employees and Their Successors. This Supplemental Pension Plan
shall be binding upon and inure to the benefit of the Employers, their successors and assigns
and each Participant and his heirs, executors, administrators and legal representatives.

	 	8.4	 	Spendthrift Provisions. No benefit payable under this Supplemental Pension Plan
shall be subject in any manner to anticipation, alienation, sale, transfer, assignment,
pledge, encumbrance or charge prior to actual receipt thereof by the payee; and any attempt so
to anticipate, alienate, sell, transfer, assign, pledge, encumber or charge prior to such
receipt shall be void; and the Employers shall not be liable in any manner for or subject to
the debts, contracts, liabilities, torts or engagements of any person entitled to any benefit
under this Supplemental Pension Plan.

	 	8.5	 	Disclosure. Each Participant shall receive a copy of this Supplemental Pension Plan,
and the Committee will make available for inspection by any Participant a copy of any rules
and regulations used by the Committee in administering this Supplemental Pension Plan.

	 	8.6	 	State Law. This Supplemental Pension Plan is established under and will be construed
according to the laws of the State of New York to the extent that such laws are not preempted
by the Employee Retirement Income Security Act of 1974, as amended, and regulations
promulgated thereunder.

	 	8.7	 	Incapacity of Recipient. In the event a Participant or Beneficiary is declared
incompetent and a guardian, conservator or other person legally charged with the care of his
person or of his estate is appointed, any benefits under this Supplemental Pension Plan to
which such Participant or Beneficiary is entitled shall be paid to such guardian, conservator
or other person legally charged with the care of his person or his estate. Except as provided
herein, when the Committee, in its sole discretion, determines that a Participant or
Beneficiary is unable to manage his financial affairs, the Committee may direct the Employer
responsible for payment to make distributions to any person for the benefit of such
Participant or Beneficiary.

	 	8.8	 	Unclaimed Benefit. Each Participant shall keep the Committee informed of his current
address. The Committee shall not be obligated to search for the whereabouts of any person.
If the location of a Participant is not made known to the Committee within three years after
the date on which any payment of the Participant’s benefit hereunder may be made, payment may
be made as though the Participant had died at the end of the three-year period. If, within
one additional year after such three-year period has elapsed, or, within three years after the
actual death of a Participant, whichever occurs first, the Committee is unable to locate any
Beneficiary of the Participant, the Participant and his Beneficiary shall forfeit all rights
to any Supplemental Pension Benefits.

	 	8.9	 	Elections, Applications, Notices. Every direction, revocation or notice authorized
or required hereunder shall be deemed delivered to: the Employers or the Committee as the
case may be: (a) on the date it is sent via electronic transmission to the Secretary of the
Committee (with a copy to the Company’s General Counsel), provided that receipt of the
electronic transmission is acknowledged by personal action of the Secretary of the Committee
or the Company’s General Counsel within three business days, (b) on the date it is personally

Beneficiary, or (c) three business days after it is sent by registered or certified mail,
postage prepaid, addressed to the Participant or Beneficiary at the last address shown for him
on the records of the Employers. Any notice required hereunder may be waived by the person
entitled thereto. Notwithstanding the foregoing, any notice required by Section 6.2 or 6.3
hereof that is sent via electronic transmission shall be subject to the electronic
transmission requirements of Section 6.2 or 6.3 hereof.

	 	8.10	 	Severability. In the event any provision of this Supplemental Pension Plan shall be
held illegal or invalid for any reason, such illegality or invalidity shall not affect the
remaining provisions of this Supplemental Pension Plan. This Supplemental Pension Plan shall
be construed and administered as if such illegal or invalid provision had never been contained
herein.

	 	8.11	 	Headings. The headings of Sections of this Supplemental Pension Plan are for

payable after a specified date or event), and a Participant’s Account shall be credited
with the amount so deferred.

	 	(b)	 	Any deferral election for a Plan Year must be made prior to the beginning of
the Plan Year, except that the election for an Employee who first becomes a Participant
after the first day of the Plan Year must be made within 30 days after the date on
which the Employee becomes eligible to participate in the Plan and shall apply only to
Compensation earned after the date of the election.

	 	(c)	 	Any deferral election for a Plan Year shall be irrevocable and may not be
changed, except that, if a Participant (i) receives a payment under Section 6.2 hereof
due to Unforseeable Emergency, the Participant’s deferral election hereunder shall be

Year that is earlier than the second Plan Year following the Plan Year in which the
Participant received such payment, or (ii) makes a hardship withdrawal under the RSP,

ARTICLE IV

CALCULATION OF CREDITS TO PLAN ACCOUNTS; VESTING

	 	4.1	 	Matching Contributions. Each Plan Year, there shall be credited to the Account of a
Participant an amount equal to (a) 100% of the amount of the Participant’s elective deferrals
under Section 4.3 hereof that do not exceed 3% of the Participant’s Supplemental RSP
Compensation for the Plan Year, plus (b) 50% of the Participant’s elective deferrals under
Section 4.3 hereof that exceed 3%, but do not exceed 6%, of the Participant’s Supplemental RSP
Compensation for the Plan Year.

	 	4.2	 	Retirement Accumulation Contributions.

	 	(a)	 	Each Plan Year, there shall be credited to the Account of a Participant an
amount equal to the excess of (i) the amount of Retirement Accumulation Contribution
that would have been contributed under Section 4.10 of the RSP on behalf of such
Participant for the Plan Year, assuming that (A) the RSP were administered without
regard to the Compensation Limitation, and (B) such Retirement Accumulation
Contribution was calculated using the definition of Compensation herein but capped at
$350,000, rather than the Participant’s compensation, as defined in the RSP, over (ii)
the amount actually contributed under Section 4.10 of the RSP on his behalf for the
Plan Year.

	 	(b)	 	The credit to the Account under this Section 4.2 on behalf of a Participant for
a Plan Year shall be calculated with the objective that the Participant should have
credited to his accounts under this Supplemental Retirement Savings Plan and the RSP
for the Plan Year the amount of Retirement Accumulation Contribution that would
otherwise have been contributed on his behalf under Section 4.10 of the RSP for the
Plan Year, assuming that such Retirement Accumulation Contribution was calculated in
accordance with (a)(i) above.

	 	4.3	 	Elective Deferrals. Each Plan Year, there shall be credited to the Account of a
Participant an amount equal to the amount that the Participant elected to defer under Section
3.3 hereof.

	 	4.4	 	No Duplication of Benefits. Notwithstanding any provision of this Supplemental
Retirement Savings Plan to the contrary, the credits to an Account under this Article IV shall
be determined and coordinated by the Committee so as to prevent any duplication of benefits
under this Plan and the RSP or any individual employment, supplemental retirement savings or
pension agreement.

	 	4.5	 	Vesting. That portion of a Participant’s Account attributable to amounts credited
under Sections 4.1 and 4.3 hereof shall be fully vested and nonforfeitable at all times. That
portion of a Participant’s Account attributable to amounts credited under Section 4.2 hereof
shall be vested and nonforfeitable to the same extent (and in the same percentage as) the
Participant’s Retirement Accumulation Account under the RSP.

ARTICLE V

INDIVIDUAL ACCOUNTS, INVESTMENTS AND VALUATIONS

	 	5.1	 	Accounts. The provisions of the RSP concerning the creation and maintenance of
individual accounts and concerning investment elections by Participants shall apply equally
under this Supplemental Retirement Savings Plan. Subaccounts shall be maintained under each
Account to separately reflect amounts attributable to credits made pursuant to Sections 4.1,
4.2 and 4.3 hereof. Amounts credited pursuant to Sections 4.1, 4.2 and 4.3 hereof shall be
credited to a Participant’s Account hereunder at substantially the same time as corresponding
amounts are credited under the RSP for the applicable Plan Year, except that matching
contributions under Section 4.1 hereof shall not be credited to a Participant’s Account
hereunder during a Plan Year until the Participant has made the maximum amount of Salary
Reduction Contributions permitted under Section 402(g) of the Code for the Plan Year. The
Committee shall maintain each Account in such manner so that the portion of the Account
attributable to amounts credited for each Plan Year may be determined.

	 	5.2	 	Investment Elections. Participant investment elections under the RSP for Salary
Reduction Contributions shall apply with respect to amounts credited to Accounts under Article
IV hereof, and such amounts shall be deemed to be invested initially in the Investment Funds
available under the RSP in the same proportion as reflected in such elections under the RSP.
Accounts will be valued at the same time as RSP accounts, except that stock of M&T Bank
Corporation will be stated in dollars instead of shares.

	 	5.3	 	Reallocation of Investments. The deemed investment of amounts already credited to a
Participant’s Account may be reallocated, at the Participant’s election, among the available
RSP Investment Funds on a quarterly basis. Such elections shall be independent of any
reallocation election made under the RSP.

	 	5.4	 	Investment Returns. Accounts will be credited with the investment return reported by
the Trust for the Investment Funds under the RSP in which the Accounts are treated as
invested.

ARTICLE VI

COMMENCEMENT AND FORM OF SUPPLEMENTAL

RETIREMENT SAVINGS PLAN BENEFIT

	 	6.1	 	Commencement of Benefits.

	 	(a)	 	Notwithstanding any other provision hereof, any payment of a Participant’s
Grandfathered Account Balance shall be made, continue to be made or commence in
accordance with the terms of the Plan, as in effect on October 3, 2004.

	 	(b)	 	Payment of any portion of a Participant’s Account balance in excess of his
Grandfathered Account Balance shall be made or commence (depending on the Participant’s
elections under Section 3.4 hereof) in the form(s), and on or as soon as practicable
after the date(s), elected by the Participant under Section 3.4 hereof, but in no event
shall such payment be made or commence (depending on the Participant’s elections under
Section 3.4 hereof) later than the later of (i) the December 31 of any Plan Year
containing the applicable payment date(s) elected by the Participant, or (ii) the
expiration of the 21/2 month period beginning on the applicable payment date(s) elected
by the Participant.

	 	6.2	 	Accelerated Payments Due to Unforseeable Emergency. Notwithstanding Section 6.1
hereof,

	 	(a)	 	The Committee may accelerate payment of all or part of a Participant’s
Grandfathered Account Balance due to financial hardship to the extent permitted under
the terms of the Plan, as in effect on October 3, 2004; and

	 	(b)	 	The Committee may accelerate payment of all or a part of that portion of a
Participant’s Account balance in excess of the Participant’s Grandfathered Account
Balance upon the occurrence of an Unforseeable Emergency. The amount of such payment
shall be limited to the amount reasonably necessary to satisfy the emergency need
(which may include amounts necessary to pay any federal, state or local income taxes or
penalties reasonably anticipated to result from such payment). The determination of
whether a Participant has experienced an Unforseeable Emergency and the amount
reasonably necessary to satisfy the emergency need shall be based on all the facts and
circumstances taking into consideration the financial resources available to the
Participant and shall be made in accordance with Section 409A of the Code.

	 	6.3	 	Mandatory Cashouts. Notwithstanding Section 6.1 hereof, if that portion of a
Participant’s Account balance in excess of the Participant’s Grandfathered Account Balance as
of the date of the Participant’s Separation from Service (including death) or Disability,
whichever is earlier, does not exceed $25,000, such portion of the Participant’s Account
balance shall be paid in a single lump sum cash payment as soon as practicable after the date
of the Participant’s Separation from Service or Disability, but not later than the later of
(i) the 15th day of the third calendar month following the date of the Participant’s
Separation from Service or Disability, as applicable, or (ii) December 31 of the calendar year
in which the Separation from Service or Disability, as applicable, occurs.

	 	6.4	 	Mandatory Delay of Certain Benefit Payments to Specified Employees. Notwithstanding
Sections 6.1 and 6.3 hereof, to the extent required by Section 409A of the Code, the Committee
shall delay payment of any portion of the Account balance of a Participant who is a “specified
employee” (as defined below) in excess of his Grandfathered Account Balance until the earlier
of (i) the date that is six months after the date of any termination of employment or other
event that constitutes the specified employee’s Separation from Service, or (ii) the date of
the specified employee’s death. Payment of any such portion of the specified employee’s
Account balance shall be made or commence (depending on the specified employee’s election
under Section 3.4 hereof) on or as soon as practicable after the expiration of the delay
period. For this purpose, the term “specified employee” shall have the same meaning as under
Section 409A of the Code.

	 	6.5	 	Discretionary Delay in Benefit Payments. Notwithstanding Sections 6.1 and 6.3
hereof, the Committee may delay payment of any portion of a Participant’s Account balance in
excess of his Grandfathered Account Balance by reason of any event(s) or condition(s)
permitted under Section 409A of the Code, including without limitation, delays relating to (i)
nondeductible Compensation payments under Section 162(m) of the Code; (ii) violations of loan
agreements; and (iii) violations of federal securities law and other applicable law.

	 	6.6	 	Payment by Employer. Benefits payable hereunder to, or on behalf of, a Participant
shall be paid by the Employer who last employed the Participant.

relative to the administration of this Supplemental Retirement Savings Plan, including by way
of illustration and not limitation, discretionary authority to interpret and construe this
Supplemental Retirement Savings Plan, to decide any dispute arising hereunder, to determine
the right of any Employee with respect to participation herein, to determine the right of any

hereof, decisions of the Committee made in good faith shall be final, conclusive and binding
upon all parties.

	 	7.2	 	Denial of Claim for Benefits.

	 	(a)	 	Claims for benefits under the Plan shall be filed with the Committee. If any
Participant or other payee (a “Claimant”) claims to be entitled to a benefit hereunder,
and the Committee determines that such claim should be denied in whole or in part, the
Committee shall notify such Claimant of its decision in writing (which may be provided
electronically). Such notification will be written in a manner calculated to be
understood by the Claimant and will contain (i) specific reasons for the denial, (ii)
specific reference to pertinent Plan provisions, (iii) a description of any additional
material or information necessary for the Claimant to perfect such claim and an

time, but not later than 90 days after the claim is received by the Committee, unless
the Committee determines that special circumstances require an extension of time for
processing the claim. If the Committee determines that such an extension of time is
required, written notice of the extension shall be provided to the Claimant prior to
the end of the initial 90-day period. The extension notice shall indicate the special
circumstances requiring the extension of time and the date by which the Committee
expects to render its decision. In no event shall the extension exceed an additional
90 days from the end of the initial 90-day period. Any electronic notification
provided by the Committee under this Article VII shall comply with the standards
imposed by 29 C.F.R. 2520.104b-1(c)(1)(i)-(iv).

	 	7.3	 	Review Procedures.

	 	(a)	 	Within 60 days after the date on which a Claimant receives a written notice of
a denied claim, the Claimant may file a written request with the Committee for a review
of the denied claim. If the Claimant requests a review of the denied claim, the
Claimant shall be entitled to submit to the Committee written comments, documents,
records and other information relating to the claim for benefits and to receive, upon
request and free of charge, reasonable access to, and copies of, all documents, records
and other information relevant to the Claimant’s claim for benefits. The Committee
shall perform its review taking into account all comments, documents, records and other
information submitted by the Claimant relating to the claim without regard to whether
such information was submitted or considered in the initial benefit determination. The
Committee will notify the Claimant of its decision in writing (which may be provided
electronically). If the claim is denied, the notification will be written in a manner
calculated to be understood by the Claimant and will contain (i) the specific reasons
for the denial, (ii) references to pertinent provisions of the Plan, (iii) a statement

action under Section 502(a) of ERISA.

	 	(b)	 	The review provided for by (a) above will be made within a reasonable period of
time, but not later than 60 days after the Committee receives the request for review,
unless the Committee determines that special circumstances require an extension of time
for processing the claim. If the Committee determines that an extension of time is
required, written notice of the extension shall be furnished to the Claimant prior to
the end of the initial 60-day period. The extension notice shall indicate the special
circumstances requiring the extension of time and the date by which the Committee
expects to render its decision. In no event shall the extension exceed an additional
60 days from the end of the initial 60-day period. If the extension of time is needed
due to the Claimant’s failure to submit information necessary to make a decision, the
period during which the Committee must make a decision shall be tolled from the date
the extension notice is sent to the Claimant until the date the Claimant responds to
the request for additional information.

ARTICLE IX

MISCELLANEOUS

	 	9.1	 	No Effect on Employment Rights. Nothing contained herein will confer upon any
Participant the right to be retained in the service of an Employer nor limit the right of an
Employer to discharge or otherwise deal with Participants without regard to the existence of
this Supplemental Retirement Savings Plan.

	 	9.2	 	Plan Unfunded. Notwithstanding any provision herein to the contrary, the benefits
offered hereunder shall constitute nothing more than unfunded, unsecured promises by each
Employer to pay the benefits determined hereunder that such Employer is obligated to pay under
Section 6.6 hereof. No provision shall at any time be made with respect to segregating any
assets of any Employer for payment of any benefits hereunder. No Participant, Beneficiary or
any other person shall have any interest in any particular assets of the Employers by reason
of the right to receive a benefit under this Supplemental Retirement Savings Plan, and any
such Participant, Beneficiary or other person shall have only the rights of a general
unsecured creditor of the Employer by whom the Participant was last employed with respect to
any rights under this Supplemental Retirement Savings Plan. Nothing contained in this
Supplemental Retirement Savings Plan shall constitute a guaranty by the Employers or any other
entity or person that the assets of any Employer will be sufficient to pay any benefit
hereunder. All expenses and fees incurred in the administration of this Supplemental
Retirement Savings Plan shall be paid by the Employers.

	 	9.3	 	Binding on Employers, Employees and Their Successors. This Supplemental Retirement
Savings Plan shall be binding upon and inure to the benefit of the Employers, their successors
and assigns and each Participant and his heirs, executors, administrators and legal
representatives.

	 	9.4	 	Spendthrift Provisions. No benefit payable under this Supplemental Retirement
Savings Plan shall be subject in any manner to anticipation, alienation, sale, transfer,
assignment, pledge, encumbrance or charge prior to actual receipt thereof by the payee; and
any attempt so to anticipate, alienate, sell, transfer, assign, pledge, encumber or charge
prior to such receipt shall be void; and the Employers shall not be liable in any manner for
or subject to the debts, contracts, liabilities, torts or engagements of any person entitled
to any benefit under this Supplemental Retirement Savings Plan.

	 	9.5	 	Disclosure. Each Participant shall receive a copy of this Supplemental Retirement
Savings Plan, and the Committee will make available for inspection by any Participant a copy
of any rules and regulations used by the Committee in administering this Plan.

	 	9.6	 	State Law. This Supplemental Retirement Savings Plan is established under and will
be construed according to the laws of the State of New York to the extent that such laws are
not preempted by the Employee Retirement Income Security Act of 1974, as amended, and
regulations promulgated thereunder.

	 	9.7	 	Incapacity of Recipient. In the event a Participant or Beneficiary is declared
incompetent and a guardian, conservator or other person legally charged with the care of his
person or of his estate is appointed, any benefits under this Supplemental Retirement Savings
Plan to which such Participant or Beneficiary is entitled shall be paid to such guardian,
conservator or other person legally charged with the care of his person or his estate. Except
as provided herein, when the Committee, in its sole discretion, determines that a Participant
or Beneficiary is unable to manage his financial affairs, the Committee may direct the
Employer responsible for payment to make distributions to any person for the benefit of such
Participant or Beneficiary.

	 	9.8	 	Unclaimed Benefit. Each Participant shall keep the Committee informed of his current
address. The Committee shall not be obligated to search for the whereabouts of any person.
If the location of a Participant is not made known to the Committee within three years after
the date on which any payment of the Participant’s benefit hereunder may be made, payment may
be made as though the Participant had died at the end of the three-year period. If, within
one additional year after such three-year period has elapsed, or, within three years after the
actual death of a Participant whichever occurs first, the Committee is unable to locate the
Beneficiary of the Participant, the Participant and his Beneficiary shall forfeit all rights
to any Supplemental Retirement Savings Plan benefits.

	 	9.9	 	Elections, Applications, Notices. Every direction, revocation or notice authorized
or required hereunder shall be deemed delivered to the Employers or the Committee as the case
may be: (a) on the date it is sent via electronic transmission to the Secretary of the

or Beneficiary within three business days, (b) the date it is personally delivered to the
Participant or Beneficiary, or (c) three business days after it is sent by registered or
certified mail, postage prepaid, addressed to the Participant or Beneficiary at the last
address shown for him on the records of the Employers. Any notice required hereunder may be
waived by the person entitled thereto. Notwithstanding the foregoing, any notice required by
Section 7.2 or 7.3 hereof that is sent via electronic transmission shall be subject to the
electronic transmission requirements of Section 7.2 or 7.3 hereof.

	 	9.10	 	Severability. In the event any provision of this Supplemental Retirement Savings
Plan shall be held illegal or invalid for any reason, such illegality or invalidity shall not
affect the remaining provisions of this Supplemental Retirement Savings Plan. This
Supplemental Retirement Savings Plan shall be construed and administered as if such illegal or
invalid provision had never been contained herein.

	 	9.11	 	Headings. The headings of Sections of this Supplemental Retirement Savings Plan are
for convenience of reference only and shall have no substantive effect on the provisions of
this Supplemental Retirement Savings Plan.

supersede any such Plan provision.

	 	3.2	 	An Employee eligible to participate in this Plan under Section
3.1 hereof shall become a Participant in this Plan on the date designated by
the Committee. Notwithstanding the foregoing, a Participant may become eligible
to have amounts credited to his Account for a year only in the event that:

	 	(a)	 	such individual has elected to make Salary
Reduction Contributions under the RSP for the year equal to at least
six percent (6%) of his Compensation not in excess of the Compensation
Limitation; and

	 	(b)	 	his Compensation for the Plan Year is in excess
of the Compensation Limitation.

	 	3.	 	Section 4.2 shall not apply to Plan Year 2005, and Sections 4.1 and 4.3(a)
shall read as follows:

	 	4.1	 	(a) There shall be credited to the Account of a Participant an
amount equal to the excess of (i) the amount which would have been contributed
under Section 5.02 of the RSP on behalf of such Participant for such Plan if
the provisions of the RSP were administered without regard to the Compensation
Limitation, but with Compensation capped at $235,840, over (ii) the amount
actually contributed under Section 5.02 of the RSP on the Participant’s behalf.

(b) The credit to a Participant’s Account under this Section 4.1 shall be
computed with the objective that the Participant should have credited to his
accounts under this Supplemental Retirement Savings Plan and the RSP the
total amount that would otherwise have been contributed on his behalf under
Section 5.02 of the RSP as of the date of such credit, had such contribution
been calculated in accordance with (a)(i) above.

	 	4.3	 	(a) In addition to any amount credited to a Participant’s
Account under Section 4.1 hereof, the Participant may elect to defer under this
Plan a percentage of that portion of the Participant’s Compensation in excess
of the Compensation Limitation, but not in excess of $235,840, equal to the
percentage of his Compensation that he has elected to defer for the Plan Year
under Section 5.01 of the RSP.

	 	4.	 	In Section 4.3(c)(ii), the phrase “12 months” shall be substituted for the
phrase “six months.”

	 	5.	 	The last sentence of Section 5.1 shall read as follows:

Amounts credited pursuant to Sections 4.1 and 4.3 hereof shall be credited to a
Participant’s Account hereunder at substantially the same time as corresponding
amounts are credited under the RSP for the Plan Year, except that such amounts shall
not be credited to a Participant’s Account hereunder during the Plan Year until the
Participant has made the minimum required contribution under Section 3.2 hereof.
