The Board of Directors of Marshall & Ilsley Corporation initially established this Directors Deferred Compensation Plan, effective as of January 1, 1985 (the “Plan”).

Article III

Administration of Accounts

3.1 Account A.

(a) Amounts allocated to a Participant’s Account A shall be deemed to be invested in Common Shares on a monthly basis, and such Participant’s Account A shall be deemed credited with the equivalent number of notional Common Shares (hereinafter referred to as “Credited Shares”) in the amount which would have been purchased on a common investment date, which will typically be any of the first five business days of any month, determined in the sole discretion of an independent brokerage agent. In addition, to the extent Credited Shares are deemed held, or shares of Fidelity Stock are deemed held, on the record date for any dividend, each Participant’s Account A shall be deemed credited with a number of additional Credited

4

Shares or shares of Fidelity Stock resulting from the reinvestment of dividends on a common investment date, which will be the date the dividend is paid in the case of dividends on Common Shares and any of the five business days after the payment of the dividend, determined in the sole discretion of an independent brokerage agent, in the case of shares of Fidelity Stock.

(b) In the event of any distribution with respect to Common Shares or Fidelity Stock other than a cash dividend, such as a stock split, stock dividend or similar transaction, each Participant’s Account A shall be credited with a number of additional notional Credited Shares, notional Fidelity Stock or other consideration as determined by the Committee in its sole discretion. Account A will be denominated in whole and fractional shares. In clarification of the foregoing, upon the occurrence of the Separation Transaction, a Participant’s Account A were deemed to hold both Common Shares and Metavante Stock determined as if the Participant were a shareholder of the Company for the number of shares in his Account A immediately prior to the Separation Transaction. Upon the occurrence of the merger of Metavante with and into Fidelity, a Participant’s Account A were deemed to hold both Common Shares and Fidelity Stock determined as if the Participant were a shareholder of Metavante for the number of shares of notional Metavante Stock in his Account A immediately prior to such merger.

(c) In the event of a Change in Control (such as the Merger) or a change in control of any other corporation whose stock is held in Account A, a Participant’s Account A shall be deemed credited with the same amount and type of consideration which a shareholder of the Company would have received holding the same number of Common Shares or other corporation’s stock as are deemed to be held in the Participant’s Account A at the time of the payment of the consideration. If there is a shareholder election as to the type of consideration received in a Change in Control, a Participant’s Account A will be deemed credited with consideration assuming that the Participant elected the maximum amount of Common Shares which is available to electing shareholders, adjusted for any proration required because of oversubscription. Notwithstanding the foregoing, if cash is received in connection with a Change in Control or other change in control, such cash will be credited to Account B.

(d) Account A will be deemed denominated in whole and fractional Common Shares or shares of Fidelity Stock.

3.2 Account B. Amounts allocated to a Participant’s Account B shall be considered to be invested in U.S. Treasury Bills having a maturity of 13 weeks. Each Participant’s Account B shall be credited with the amount of interest which would have been earned for any applicable period if the balance in a Participant’s Account B were invested in U.S. Treasury Bills with a maturity of 13 weeks. The rate of interest applied will be determined by the Committee or its designees from time to time in accordance with guidelines disclosed to the Participants.

3.3 Account C.

(a) Net Shares and Restricted Stock Units deferred pursuant to a Participant’s timely-filed election shall be deemed to be allocated to a Participant’s Account C and shall be considered to be invested in notional Credited Shares or after the Separation Transaction and the merger of Metavante with and into Fidelity, shares of Fidelity Stock, if applicable. In addition,

5

to the extent notional Credited Shares or shares of notional Fidelity Stock are deemed held on the record date for any dividend, each Participant’s Account C shall be deemed credited with a number of additional notional Credited Shares or shares of notional Fidelity Stock resulting from the reinvestment of dividends on a common investment date, which will be the date the dividend is paid in the case of dividends on Common Shares and any of the first five business days after the payment of the dividend, determined in the sole discretion of an independent brokerage agent, in the case of shares of Fidelity Stock.

(b) In the event of any distribution with respect to Common Shares or shares of Fidelity Stock other than a cash dividend, such as a stock split, stock dividend or similar transaction, each Participant’s Account C shall be deemed credited with a number of additional notional Credited Shares, shares of notional Fidelity Stock or other consideration as determined by the Committee in its sole discretion. Account C will be denominated in whole and fractional Common Shares or Fidelity Stock. In clarification of the foregoing, upon the occurrence of the Separation Transaction, a Participant’s Account C were deemed to hold both Common Shares and Metavante Stock determined as if the Participant were a shareholder of the Company for the number of shares in his Account C (including Restricted Stock Units) immediately prior to the Separation Transaction. Upon the occurrence of the merger of Metavante with and into Fidelity, a Participant’s Account A were deemed to hold both Common Shares and Fidelity Stock determined as if the Participant were a shareholder of Metavante for the number of shares of Metavante Stock in his Account C (including Restricted Stock Units) immediately prior to such merger.

(c) In the event of a Change in Control or a change in control of any other corporation whose stock is held in Account C, a Participant’s Account C shall be deemed credited with the same amount and type of consideration which a shareholder of the Company would have received holding the same number of Common Shares as are held in the Participant’s Account C at the time of the payment of the consideration. If there is a shareholder election as to the type of consideration received in a Change in Control, a Participant’s Account C will be deemed credited with consideration assuming that the Participant elected the maximum amount of stock which is available to electing shareholders, adjusted for any proration required because of oversubscription. Notwithstanding the foregoing, if cash is received in connection with a Change in Control or other change in control, such cash will be credited to Account B.

(d) Account C will be deemed denominated in whole and fractional Common Shares or Fidelity Stock. While any Restricted Stock Units that fail to vest will be forfeited, consistent with the treatment of Restricted Shares, any dividends credited as regards Restricted Stock Units shall not be forfeited.

3.4. Investment Elections for Accounts A and C After the Separation Transaction and the Merger of Metavante and Fidelity.

(a) After the Separation Transaction, Accounts A and C of a Participant were deemed credited with both Common Shares and Metavante Stock. After the merger of Metavante with and into Fidelity, Accounts A and C of a Participant that previously held Metavante Stock were deemed credited with Fidelity Stock.

6

(b) The Participant may constructively sell any or all vested shares of Fidelity Stock by making a new Investment Election, no later than 3 PM Central Time on the last business day of such month, setting forth the number of shares to be sold. The number of Common Shares deemed purchased will equal the number of Common Shares that could have been purchased by the Trust with the proceeds recognized from the sale of such Fidelity Stock on the last business day of the applicable month, which notional Common Shares will then be deemed credited to Account A or C which previously held the shares of Fidelity Stock that were sold. Any transaction costs incurred by the Trust will reduce the proceeds available to be deemed invested in notional Common Shares. Notwithstanding the foregoing, if the Participant is subject to the Company’s insider trading policy, an Investment Election under this Section 3.4(b) can only be made when the trading window is open, and will become irrevocable as to investments in notional Common Shares when the trading window closes, even if it is prior to the due date for the election.

(c) A Participant may constructively sell any or all Restricted Stock Units of Fidelity Stock by making a new Investment Election, no later than 3 PM Central Time on the last business day of such month, setting forth the number of shares underlying the Restricted Stock Units to be sold. The number of Common Shares deemed purchased will equal the number of Common Shares that could have been purchased by the Trust with the proceeds recognized from the sale of such Fidelity Stock on the last business day of the applicable month, which notional Common Shares will then be deemed credited to Account A or C which previously held the shares of Fidelity Stock that were sold. Any transaction costs incurred by the Trust will reduce the proceeds available to be deemed invested in Common Shares. Any restrictions governing the Restricted Stock Units of Fidelity Stock sold will govern the notional Common Shares deemed purchased with the proceeds of the deemed sale of such Fidelity Stock. Notwithstanding the foregoing, if the Participant is subject to the Company’s insider trading policy, an Investment Election under this Section 3.4(c) can only be made when the trading window is open, and will become irrevocable as to investments in notional Common Shares when the trading window closes, even if it is prior to the due date for the election.

(d) A Participant’s Accounts A and C shall reflect only the performance of Common Shares and Fidelity Stock, if any is held in such Account A or C, and the Participant shall have no property right or security interest in any Common Shares or share of Fidelity Stock, which, with respect to Fidelity Stock only, may be held by the Trust to provide for the payment of benefits under this Plan.

3.5. Change of Accounts. Once amounts have been allocated to Account A, Account B or Account C, these amounts must remain in Account A, B or C until such amounts are distributed to the Participant pursuant to Article IV hereof. Notwithstanding the foregoing, if cash is received in connection with a Change in Control or other change in control, such cash will be automatically credited to Account B. Upon a Change in Control, the Company, the Administrator and any successors thereto may not change the investment choices available to Participants hereunder without the consent of a majority of the holders of Account balances under the Plan.

3.6. Nature of Account. The accounts established for each Participant hereunder and assets, if any, acquired by the Company or the Trust to measure a Participant’s benefits

7

hereunder, shall not constitute or be treated for any reason as a trust for, property of or a security interest for the benefit of, a Participant, his beneficiaries or any other person. Participant and the Company acknowledge that the Plan constitutes a promise by the Company to pay benefits to the Participants or their beneficiaries, that Participants’ rights hereunder (by electing to defer Compensation hereunder) are limited to those of general unsecured creditors of the Company or the Affiliate where a Participant served as a director and that the establishment of the Plan, acquisition of assets to measure Participant’s benefits hereunder or deferral of all or any portion of a Participants’ Compensation hereunder does not prevent any property of the Company, the Affiliate where a Participant served as a director or the Trust from being subject to the right of all the Company’s creditors (or if the Participant did not serve as a director of the Company, the creditors of the Affiliate where a Participant served as a director). The Company shall contribute all contributions hereunder to the Trust which will comply with the requirements of the Internal Revenue Service’s model trust, as described in Revenue Procedure 92-64.

Article IV

Distributions

4.1 Normal Distributions. Except as otherwise provided in this Paragraph, distribution of the amounts credited to a Participant’s account(s) shall be made to the Participant in either a lump sum or in such number of annual installments (which shall be not less than two (2) or more than ten (10) installments) as are elected by the Participant by written notice to the Committee at least twelve (12) months before he ceases to be a Director or, if no such election is made, in five (5) annual installments. A Participant may make a separate election for each account. Lump sum payments shall be made no later than February 15 of the year after the year in which a director’s service terminates. Annual installment payments shall be made no later than February 15 of any year and shall commence in the year after termination of service as a director. The amount of each such annual installment from Accounts A and C shall be equal to (i) the total number of shares of Fidelity Stock deemed credited to the Participant’s Account A and/or C as of the last day of the prior year, to the extent Account A or C is denominated in shares of Fidelity Stock and/or (ii) on and after July 6, 2011, cash to the extent the amounts in the relevant sub-accounts of Account B are denominated in notional Common Shares; provided, however, that the Participant may elect to have such cash distributed to a brokerage account in accordance with the terms and provisions of the election documentation provided to such Participant by the Company, which shall include an agreement by the Company to cause any applicable fees and commissions to be waived to the extent such cash distribution is used to purchase Common Shares in accordance with the terms and provisions of such election documentation. The amount of each such annual installment from the sub-accounts of Account B shall be equal to the total dollar amount credited to the Participant’s Account B as of the last day of the prior year, each multiplied by a fraction, the numerator of which is one (1) and the denominator of which is the remaining number of unpaid annual installments remaining on such date. The last annual installment shall be of all the cash with respect to the notional common shares, the shares of Fidelity Stock, or cash remaining in the Participant’s account(s). The Committee shall make whatever adjustments may be necessary to the amounts credited to a Participant’s account(s) to reflect any distributions made hereunder. Notwithstanding anything herein contained to the contrary, the Company may allow Participants to make a separate distribution election to be applicable if a Change in Control occurs under certain circumstances.

8

In the case of a Change in Control election, there need not be a requirement that service terminate before distributions commence.

4.2 Distribution After Death of a Participant. If a Participant ceases to be a Director by reason of his death or if he dies after he is no longer a Director but prior to the distribution to him of all amounts payable to him under the Plan, the amounts that would otherwise be distributable to him, if living, shall be distributed to his designated beneficiary or beneficiaries and any reference to a Participant in Paragraph 4.1, above, shall be deemed to include a reference to his designated beneficiary or beneficiaries unless the Participant otherwise elects on forms provided by the Committee. All beneficiary designations shall be made in such form and manner as from time to time may be prescribed by the Committee. A Participant from time to time may revoke or change any beneficiary designation on file with the Committee. If there is no effective beneficiary designation on file with the Committee at the time of the Participant’s death, distribution of amounts otherwise payable to the deceased Participant under this Plan shall be made to his estate or its successors or assigns. If a beneficiary designated by a Participant to receive his benefit shall survive the Participant but die before receiving all distributions hereunder, the balance thereof shall be paid to such deceased beneficiary’s estate or its successors or assigns, unless the deceased Participant’s beneficiary designation provides otherwise.

4.3 Accounts Less than USD $25,000. Notwithstanding anything herein contained to the contrary, if the sum of the Fair Market Value of the notional Common Shares and notional Fidelity Stock, if any, deemed to be held in a Participant’s Accounts A and C and the dollar amount in a Participant’s Account B is less than USD $25,000 at the end of any Plan Year after he ceases to be a Director, the Committee may, in its sole discretion, direct that the account(s) be distributed in a lump sum no later than the February 15 following the year in which this occurs. The notional Common Shares deemed invested in Accounts A and C shall be distributed in cash, whether distributed in the form of cash or distributed to a brokerage account pursuant to Section 4.1 hereof.

Article V

5.1 Rights of Participant. No Participant or any other person shall have any interest in any fund or in any specific asset or assets of the Company by reason of any amounts deemed credited to any Account hereunder, nor any right to exercise any of the rights or privileges of a stockholder with respect to any notional securities deemed credited to a Participant’s Account A or Account C under the Plan, nor any right to receive any distributions under the Plan except as and to the extent expressly provided in the Plan.
