10. Payment of Taxes.

10.1 Internal Revenue Code Section 83(b) Election. In the event that Grantee makes an Internal Revenue Code Section 83(b) election with respect to the Restricted Shares, Grantee shall satisfy all then applicable federal, state or local withholding tax obligations arising from that election (a) by payment of cash or (b) if and to the extent then permitted by PNC and subject to such terms and conditions as PNC

may from time to time establish, by physical delivery to PNC of certificates for whole shares of PNC common stock that are not subject to any contractual restriction, pledge or other encumbrance and that have been owned by Grantee for at least six (6) months and, in the case of restricted stock, for which it has been at least six (6) months since the restrictions lapsed, or by a combination of cash and such stock. Any such tax election shall be made pursuant to a form to be provided to Grantee by PNC on request. For purposes of this Section 10.1, shares of PNC common stock that are used to satisfy applicable withholding tax obligations will be valued at their Fair Market Value on the date the tax withholding obligation arises. Grantee will provide to PNC a copy of any Internal Revenue Code Section 83(b) election filed by Grantee with respect to the Restricted Shares not later than ten (10) days after the filing of such election.

10.2 Other Tax Liabilities. Where Grantee has not previously satisfied all applicable withholding tax obligations, PNC will, at the time the tax withholding obligation arises, retain sufficient whole shares of PNC common stock from the shares granted pursuant to the Agreement to satisfy the minimum amount of taxes then required to be withheld by the Corporation in connection with the Restricted Shares. For purposes of this Section 10.2, shares of PNC common stock retained to satisfy applicable withholding tax requirements will be valued at their Fair Market Value on the date the tax withholding obligation arises.

PNC will not retain more than the number of shares sufficient to satisfy the minimum amount of taxes then required to be withheld in connection with the Restricted Shares. If Grantee desires to have an additional amount withheld above the required minimum, up to Grantee’s W-4 obligation if higher, and if PNC so permits, Grantee may elect to satisfy this additional withholding either: (a) by payment of cash; or (b) if and to the extent then permitted by PNC and subject to such terms and conditions as PNC may from time to time establish, using whole shares of PNC common stock (either by physical delivery to PNC of certificates for the shares or through PNC’s share attestation procedure) that are not subject to any contractual restriction, pledge or other encumbrance and that have been owned by Grantee for at least six (6) months and, in the case of restricted stock, for which it has been at least six (6) months since the restrictions lapsed. Any such tax election shall be made pursuant to a form provided by PNC. Shares of PNC common stock that are used for this purpose will be valued at their Fair Market Value on the date the tax withholding obligation arises. If Grantee’s W-4 obligation does not exceed the required minimum withholding in connection with the Restricted Shares, no additional withholding may be made.

11. Employment. Neither the granting and issuance of the Restricted Shares nor any term or provision of the Agreement shall constitute or be evidence of any understanding, expressed or implied, on the part of PNC or any subsidiary to employ Grantee for any period or in any way alter Grantee’s status as an employee at will.

12. Subject to the Plan and the Committee. In all respects the Grant and the Agreement are subject to the terms and conditions of the Plan, which has been made available to Grantee and is incorporated herein by reference; provided, however, the

terms of the Plan shall not be considered an enlargement of any benefits under the Agreement. Further, the Grant and the Agreement are subject to any interpretation of, and any rules and regulations issued by, the Committee or its delegate or under the authority of the Committee, whether made or issued before or after the Grant Date.

13. Headings; Entire Agreement. Headings used in the Agreement are provided for reference and convenience only, shall not be considered part of the Agreement, and shall not be employed in the construction of the Agreement. The Agreement constitutes the entire agreement between Grantee and PNC and supersedes all other discussions, negotiations, correspondence, representations, understandings and agreements between the parties with respect to the subject matter hereof. Notwithstanding the foregoing, nothing in the Agreement shall affect the survival of the Employment Letter Agreement, including the provisions in said Employment Letter Agreement providing for the survival of certain provisions of the Amended and Restated Executive Severance Agreement by and among Mercantile Bankshares Corporation, Mercantile-Safe Deposit & Trust Company and Grantee effective as of March 29, 2006.
