The deferred compensation provided hereunder is intended to supplement the benefits provided under The Bank of New York Mellon Corporation 401(k) Savings Plan (the “401(k) Plan”) to such employees whose Retirement Contributions under the 401(k) Plan are limited due to the dollar maximums imposed on “qualified” plans by Section 401(a)(17) of the Internal Revenue Code of 1986, as amended (“Code”).

The Corporation hereby declares that its intention that the Plan be operated in compliance with the American Jobs Creation Act of 2004 and Section 409A of the Code.

3.01 Amount of Supplemental Retirement Contribution

In respect of each Eligible Employee for any Plan Year, the Corporation agrees to credit to the Participant’s Notional Account a notional amount (the “Supplemental Retirement Contribution”) for such Plan Year equal to:

(a) The maximum Retirement Contribution to which the Participant would have been entitled under the 401(k) Plan for the same Plan Year but for the application of the 401(a)(17) Limit.

- 4 -

No Supplemental Retirement Contribution will be credited to the Participant’s Notional Account for any Plan Year for which a Retirement Contribution was not made on behalf of the Participant under the 401(k) Plan.

3.02 Establishment of Notional Accounts.

“Notional Account” means the record-keeping device used by the Corporation to measure and determine the amounts to be paid to a Participant under the Plan. Separate Notional Accounts will be established for each Participant and as may be otherwise required. Notional Accounts shall be deemed to be credited with Notional gains or losses as provided in Section 3.06 from the date a Supplemental Retirement Contribution is credited in accordance with Section 3.03 through the Valuation Date.

3.03 Crediting of Supplemental Retirement Contributions; Earnings and Taxes

The Supplemental Retirement Contribution to which a Participant is entitled shall be credited to the Participant’s Notional Accounts as of the Deemed Deposit Date. To the extent the Supplemental Retirement Contribution is not credited on the same date as the Retirement Contribution to which it relates, it shall be adjusted to reflect earnings and losses based on the Notional Investment Options elected (or deemed elected) for the period beginning on the Deemed Deposit Date and ending on the crediting date. Any withholding of taxes or other amounts with respect to deferred compensation that is elected by the Participant and/or required by Federal, state or local law on account of such deemed crediting shall be withheld from the Participant’s Eligible Compensation and no amounts shall be withheld from the Supplemental Retirement Contribution deemed credited to the Participant hereunder.

3.04 Investment of Notional Account.

(a) Amounts Subject to Participant Direction. Subject to (b), all amounts credited to a Participant’s Notional Account shall be notionally invested at the direction (or deemed direction) of the Participant in one (1) or more of the Notional Investment Options. Except as otherwise provided in (b) with respect to a Participant’s initial investment election, Participant investment elections under the 401(k) Plan shall not be applied to the corresponding Notional Investment Options under this Plan.

(b) Initial Investments. Until such time as a Participant makes his investment elections on a form provided by or acceptable to the Plan Manager, such Participant’s Notional Account shall be notionally invested in the same Notional Investment Options as are the Participant’s Retirement Contributions actually invested under the 401(k) Plan determined as of the date the Participant first became a Participant under this Plan; provided, however, that to the extent any such Participant’s Retirement Contributions are invested through the Self-Directed Account or in the Employer Stock Fund, the portion of the Participant’s Notional Account that would otherwise be invested in such options shall be notionally invested in the Notional Investment Option which corresponds to the Qualified Default Investment Option under the 401(k) Plan; provided, further, that to the extent any such Participant has no investment elections in effect under the 401(k) Plan, the Participant’s entire Notional Account shall be invested in the Notional Investment Option which corresponds to such Qualified Default Investment Option

- 5 -

(collectively, the “Default Investments”). By way of clarification and not limitation, a Participant’s Default Investments will not be affected by any election to change his or her separate investment elections under the 401(k) until such time, if ever, as the Participant makes an affirmative election to change his or her Default Investments under this Plan in accordance with Section 3.04(c).

(c) Change in Investment Elections. A Participant may elect to change the manner in which: (i) future Supplemental Retirement Contributions and/or (ii) amounts previously credited to the Participant’s Notional Account; are notionally invested by timely submitting the change to the Plan Manager on a form provided by or acceptable to the Plan Manager. Such changes may be made daily in accordance with the administrative rules established by the Plan Manager and, to the extent administratively practicable, shall be effective as of the Market Close on the Trade Date as such terms are defined in Article IV, Investment and Valuation of Accounts, of the 401(k) Plan.

(d) Limitations on Investments. Notwithstanding anything contained in this Plan to the contrary, a Participant’s investment directions with respect to Notional Investment Options shall be subject to the same suspensions, limitations, terminations or restrictions applicable to similar actual investment directions under the 401(k) Plan; including, by way of illustration and not limitation, suspensions, limitations, terminations or restrictions which: (i) limit the number of investment directions to a particular Notional Investment Option over a stated period of time; (ii) establish daily trading deadlines for receipt of Participant directions to a particular Notional Investment Option (or all Notional Investment Options) earlier than the deadline applicable to investment directions to other Notional Investment Options under the Plan or to the deadline applicable to the trading in the Notional Investment Option outside the Plan; (iii) impose fees, payable by the Participant to the affected Notional Investment Option, on redemptions of investments in a particular option which occur within a stated period of time; (iv) require the temporary or permanent manual processing of investment directions of Participants determined to have violated any established and communicated trading restriction or limitation; and (v) require the temporary or permanent termination of a Participant’s entitlement to make investments in a particular Notional Investment Option.

3.05 Valuation of Notional Investment Options.

A Participant’s interest in each Notional Investment Option shall be represented by “shares” of participation. The value of each Notional Investment Option and the net asset value of a share in each Notional Investment Option shall be determined in the same manner as such option and share values are determined for the corresponding investment options under the 401(k) Plan. The Plan Manager shall be entitled to rely on such valuations of any Notional Investment Options provided by an investment manager, the sponsor of an investment fund included within the Notional Investment Options or any other person, provided that such reliance is consistent with the provisions of applicable law.

3.06 Valuation of Notional Accounts.

A Participant’s Notional Account reflects his interest in each Notional Investment Option. After determining the share values of each Notional Investment Option in accordance with Section

- 6 -

3.05, each Notional Investment Option held in the Participant’s Notional Account shall be: (a) credited with shares to reflect the sum of any Supplemental Retirement Contributions, dividends, fund transfers or other increments invested in such Option and (b) debited with shares to reflect the sum of any forfeitures, fund transfers, or other decrements to such Option; since the prior Valuation Date. All such credits and debits shall be made in accordance with the procedures set forth in Article IV, Investment and Valuation of Accounts, of the 401(k) Plan. The value of a Participant’s Notional Account as of any time of reference shall be the aggregate value of the shares of such Notional Investment Options so credited to the Participant’s Account.

3.07 Vesting of Notional Accounts.

A Participant’s interest in amounts credited to his Notional Account shall fully vest upon the Participant’s completion of three (3) Years of Service; provided, however, that such Participant shall become fully vested with respect to such amounts if, while an employee of the Corporation, he attains his Retirement Date, incurs a Disability, or dies. For purposes of determining Years of Service under the preceding sentence, if a Participant who is not vested in his Notional Account incurs a Break in Service and he is later reemployed as an employee, the Service to which he was entitled before the Break in Service shall be restored to him effective as of his Employment Commencement Date. If a Participant who is not vested in his Notional Account terminates employment with the Corporation and is not later reemployed as an employee, his Notional Account shall be forfeited as of the Valuation Date which coincides with or next follows the date on which the Participant incurs five (5) consecutive one (1) year Breaks in Service (as defined in Article I, Definitions, of the 401(k) Plan). If, after the Participant’s termination of employment from all members of the Controlled Group, the Participant receives a distribution of the entire vested portion of his Accrued Benefit and he is later reemployed prior to incurring five (5) consecutive one (1) year Breaks in Service, any forfeited amount of his Notional Account shall be restored.

3.08 Statement of Notional Account.

The Corporation shall submit to each Participant periodic statements setting forth the balance to the credit of the Notional Account maintained for the Participant.

3.09 Payment of Notional Account

(a) Payment Events. A Participant’s Notional Account shall become payable upon the first to occur of a Participant’s Retirement, death, Disability or other Separation from Service from the Corporation and all members of the Controlled Group and without regard to whether the Participant elects to commence his benefit under the 401(k) Plan. By way of clarification and not limitation, a Participant’s Notional Account shall not be available for loans, hardship withdrawals or any other form of withdrawal or distribution not described in the prior sentence.

(b) Form of Payment. A Participant’s Notional Account shall be paid in the form of single lump sum payment.

(c) Time of Payment. Subject to (d), a Participant’s Notional Account shall be paid as soon as administratively possible on or after the first day of the month following the

- 7 -

occurrence of a payment event described in (a); provided, however, that such Account shall be paid in the same taxable year if the payment event occurs prior to December 1^st.

(d) Compliance of Plan with Section 409A. Notwithstanding anything to the contrary in (c) or in any other provision of this Plan, if a Participant is a “specified employee” as determined pursuant to Section 409A of the Code (“Section 409A”) as of the date of such Participant’s “separation from service” (within the meaning of Treasury Regulation 1.409A-1(h)) and if any payment of a Participant’s Notional Account under this Plan both (i) constitutes a “deferral of compensation” within the meaning of Section 409A and (ii) cannot be paid in the manner otherwise provided without subjecting the Participant to “additional tax”, interest or penalties under Section 409A, then any such payment that is payable during the first six months following the Participant’s “separation from service” shall be paid or provided to the Participant in a cash lump-sum as soon as administratively possible on or after the first business day of the seventh calendar month following the month in which the Participant’s “separation from service” occurs or, if earlier, at the Participant’s death.

(e) Value of Notional Account. The value of a Participant’s Notional Account to be distributed in accordance with this Section 3.09 shall be determined as of the Valuation immediately preceding the payment date determined in accordance with this Section.

(f) Source of Payment. The Corporation shall make any and all distributions pursuant to this Plan in cash out of its general assets.

(g) Withholding and Payroll Taxes. The Corporation shall withhold from payments made hereunder any taxes required to be withheld from such payments under Federal, state or local law.

(h) No Acceleration. To assure avoidance of payment acceleration which would be impermissible and subject to penalty under Code Section 409A, when payment is to be made in or for a particular month, payment cannot be made earlier than that month.

4.01 Amendment.

The Corporation shall have the right to amend this Plan at any time; provided, however, that no amendment shall directly or indirectly deprive any Participant or Beneficiary of the amount accrued to the Participant’s Notional Account as of the date of the amendment. Notwithstanding anything in the preceding sentence to the contrary, the Committee shall have the power to amend the Plan to the extent authorized by Section 8.02.

4.02 Termination.

The Corporation shall have the right to partially or completely terminate the Plan if, in its judgment, the tax, accounting or other effects of the continuation of the Plan or potential payments thereunder would not be in the best interests of the Corporation. The Corporation may also determine to provide for payouts to Participants in connection with such partial or complete termination, provided such payouts are consistent with Code Section 409A.

- 8 -

The Corporation shall, except as otherwise provided hereunder, pay all amounts payable hereunder only to the person or persons entitled thereto hereunder, and all such payments shall be made directly into the hands of each such person or persons and not into the hands of any other person or corporation whatsoever, so that said payments may not be liable for the debts, contracts or engagements of any such designated person or persons, or taken in execution by attachment or garnishment or by any other legal or equitable proceedings, nor shall any such designated person or persons have any right to alienate, arbitrate, execute, pledge, encumber, or assign any such payments or the benefits or proceeds thereof. If the person entitled to receive payment be a minor, or a person of unsound mind, whether or not adjudicated incompetent, the Corporation, upon direction of the Committee, may make such payments to such person or persons, corporation or corporations as may be, or be acting as, parent or legal or natural guardian of such minor or person of unsound mind. The signed receipt of such person or corporation shall be a full and complete discharge to the Corporation for any such payments. Notwithstanding the foregoing, the Committee may assign and/or accelerate the payment of a Participant’s vested Notional Account balance to an individual other than the Participant as may be necessary to comply with a “qualified domestic relations order” as defined by and under the terms provided in Code Section 414(p), Code Section 409A and other applicable authorities.

The Corporation shall be responsible for the payment of all benefits provided under the Plan. At its discretion, the Corporation may establish one or more trusts, with such trustees as the Corporation or the Committee may approve, for the purpose of providing for the payment of such benefits. Such trust or trusts may be irrevocable, but the assets thereof shall be subject to the claims of the Corporation’s creditors. To the extent any benefits provided under the Plan are actually paid from any such trust, the Corporation shall have no further obligation with respect thereto, but to the extent not so paid, such benefits shall remain the obligation of, and shall be paid by, the Corporation.

- 9 -

ERISA or regulations thereunder with respect to any Plan Year, then such Participant will not be eligible to receive a Supplemental Retirement Contribution under this Plan for any such Plan Year.

7.05 Forfeitures to the Corporation

In case the Corporation is unable within three (3) years after payment is due to a Participant, or within three (3) years after payment is due to the Beneficiary or estate of a deceased Participant, to make such payment to him or her or his or her Beneficiary, executor or administrator because it cannot ascertain his or her whereabouts or the identity or whereabouts of his or her Beneficiary, executor or administrator by mailing to the last known address shown on the Employer’s or the Corporation’s records, and neither he, his or her Beneficiary, nor his or her executor or administrator had made written claim therefore before the expiration of the aforesaid time limit, then in such case, the amount due shall be forfeited to the Corporation.

7.06 Corporate Successors

The Plan shall not be automatically terminated by a transfer or sale of assets of the Corporation or by the merger or consolidation of the Corporation into or with any other corporation or other entity, but the Plan shall be continued after such sale, merger or consolidation only if and to the extent that the transferee, purchaser or successor entity, agrees to continue the Plan. In the event that the Plan is not continued by the transferee, purchaser or successor entity, then the Plan shall terminate subject to the provisions of Section 4.00.

8.04 Establishment of Rules.

The Committee shall have specific authority in its sole discretion to construe and interpret the terms of the Plan related to its powers and duties, and to the extent that the terms of the Plan are incomplete, the Committee shall have authority to establish such rules or regulations related to its powers and duties as it may deem necessary and proper to carry out the intent of the Corporation as to the purposes of the Plan.
