                                                                     APPENDIX A

                        PROVIDENT BANKSHARES CORPORATION
                     AMENDED AND RESTATED STOCK OPTION PLAN


      1. Purpose. This Stock Option Plan (herein the "Plan") is intended as an
         -------
employment incentive and to encourage stock ownership by certain directors, key
officers and employees of the Corporation and any Subsidiary, so that they may
increase their proprietary interest in the Corporation's success. In this way,
the Corporation will be assisted in its efforts to attract and retain highly
qualified management personnel.

      2. Administration. The Plan shall be administered, construed and
         --------------
interpreted by the Compensation Committee, as appointed by the Board of
Directors of the Corporation as defined under Section 6(f) (herein the
"Committee"). The Committee is authorized, subject to the provisions of the
Plan, to establish such rules and regulations as it sees necessary for the
proper administration of the Plan and to make whatever determinations and
interpretations in connection with the Plan it sees as necessary or advisable.
All determinations and interpretations made by the Committee shall be binding
and conclusive on all participants in the Plan and on their legal
representatives and beneficiaries. The Board of Directors may from time to time
remove members from, or add members to, the Committee, and vacancies on the
Committee, however caused, shall be filled by the Board of Directors. Subject to
the provisions of the Plan, the Committee shall determine:

            (a)   The directors, officers and employees to who options shall be 
                  granted;

            (b)   The number of shares on which options shall be granted to each
                  director, officer and employee;

            (c)   The price to be paid for the shares upon the exercise of each
                  option;

            (d)   The termination date of such options; and

            (e)   All other matters deemed necessary or advisable for the
                  administration of the Plan.

      No member of the Board of Directors or the Committee shall be liable for
any action or determination made in good faith, and the members shall be
entitled to indemnification and reimbursement in the manner provided in the
Corporation's Articles of Incorporation or otherwise provided by law. The
Committee shall furnish the Board with copies of all decisions, orders and
determinations made by the Committee.

      3. Eligibility. Subject to the terms herein, directors, key salaried
         -----------
officers and employees of the Corporation, or of any present or future
Subsidiary, as the Committee shall



 2



determine from time to time shall be eligible to participate in the Plan. An
Optionee may hold more than one (1) option, but only on the terms and conditions
herein set forth.

      4. Stock. The stock subject to the options and other provisions of the
         -----
Plan shall be shares of the Corporation's $1.00 par value common stock which is
authorized but unissued, or reacquired common stock (herein sometimes "Common
Stock"). The maximum aggregate number of shares issued under the Plan shall be
2,024,301 (as of January 21, 1998) shares, subject to adjustment in accordance
with the provisions of Section 5(g) hereof. This authorization shall be
increased automatically on each succeeding annual anniversary of the adoption of
the Plan so that the number of shares authorized under the Plan equals 17% of
the then outstanding shares of Corporation Common Stock.

      In the event that any outstanding option under the Plan for any reason
expires or is terminated prior to the end of the period during which options may
be granted under the Plan, the shares of Common Stock allocable to the
unexercised portion of such option may again be subjected to an option under the
Plan.

      No participant under this Plan may receive awards with respect to shares
of Common Stock that exceeds 350,000 shares in any calendar year.

      5. Terms and Conditions of Options. Stock options granted pursuant to the
         -------------------------------
Plan to eligible employees shall be evidenced by agreements in such form as the
Committee shall, from time to time, approve, which agreements shall in substance
include and comply with and be subject to the following terms and conditions:

            (a) Medium and Time of Payment. The option price shall be payable in
                --------------------------
United States dollars upon the exercise of the option and may be paid in cash or
by certified check, bank draft or money order payable to the order of the
Corporation. Stock options may be exercised pursuant to a "cashless exercise" of
an option in accordance with applicable securities laws. Payment of the purchase
price may be made, in whole or in part, through the surrender of shares of the
Common Stock of the Corporation at the Fair Market Value of such shares on the
date of surrender determined in the manner described in Section 6(g).

            (b) Number of Shares. The option shall state the total number of
                ----------------
shares to which it pertains. No option may be exercised for less than one
hundred (100) shares unless the issue of a lesser number is enough to exhaust
the option.

            (c) Option Price. The option price shall not be less than the fair
                ------------
market value of the shares of Common Stock of the Corporation on the date that
the option is granted. The Fair Market Value is defined under Section 6(g),
except that for the initial grant of options under the Plan, the "public
offering price" as defined in the Form S-1 Registration Statement filed by the
Corporation with the Securities and Exchange Commission shall be deemed to be
Fair Market Value per share of the Common Stock. The "date that the option is
granted" shall be the

                                        2

 3



date identified in the stock option agreement; provided, however, that the
Optionee shall have no rights under such option until he executes the option
agreement described in this Section.

            (d) Expiration of Options. Each option granted under the Plan shall
                ---------------------
expire not more than ten (10 ) years from the date such option is granted, as
determined by the Committee.

            (e) Date of Exercise. Except as may otherwise be determined by the
                ----------------
Committee at the time such option is granted, an option is fully vested and may
be exercised at any time immediately after: (i) a Change in Control, as defined
in Paragraph 6(a) hereof; or (ii) the date that the option or right is granted
as to not more than one-half (1/2) of the shares of Common Stock to which it
pertains. As of the first anniversary of the date that the option is granted,
the option may be exercised as to the remaining one-half (1/2) of the shares of
Common Stock to which it pertains. Notwithstanding the above, the Committee may,
in its sole discretion, accelerate the time at which any stock option may be
exercised in whole or in part.

      Except as herein otherwise provided, any option may be exercised in whole
at any time, or in part from time to time, during its term.

            (f) Termination of Employment.
                -------------------------

                  (i) In the event an Optionee ceases to be a director, officer
or employee of the Corporation or a Subsidiary due to death or Disability, all
of the Optionee's options shall immediately become fully vested and exercisable
and shall remain so for a period of sixty (60) days from the date of termination
of service as a director or officer or of employment, but in no event after
their respective expiration dates.

                  (ii) In the event an Optionee ceases to be director, officer
or employee of the Corporation or a Subsidiary as a result of Retirement, all of
the Optionee's options that were fully vested and exercisable on the date of
termination of service as a director or officer or of employment shall remain
fully vested and exercisable and shall remain so until their respective
termination dates. All of the Optionee's options that were not fully vested and
exercisable on such date shall be terminated immediately. Notwithstanding the
above, in the event an Optionee ceases to be a director of the Corporation as a
result of Retirement within one (1) year of the effective date of the Plan, all
of such Optionee's options shall immediately become fully vested and exercisable
and shall remain so until the respective termination period of the option.

                  (iii) In the event an Optionee ceases to be a director,
officer or employee of the Corporation or a Subsidiary for any reason whatsoever
other than death, Disability or Retirement, all of the Optionee's options that
were fully vested and exercisable on the date of termination of service as
director or officer or of employment shall remain fully vested and shall be
exercisable for a period of thirty (30) days from said date of termination of
service, but in no event later than the termination period of the option. All of
the Optionee's

                                        3

 4



options that were not fully vested and exercisable on said date of termination
shall be terminated immediately.

            (g) Adjustments on Changes in Stock. In the event of any change in
                -------------------------------
the outstanding shares of Common Stock of the Corporation by reason of any stock
dividend or split, recapitalization, merger, consolidation, spin-off,
reorganization, combination or exchange of shares, or other similar corporate
change, or other increase or decrease in such shares without receipt or payment
of consideration by the Corporation, the Committee, in its discretion, may deem
it appropriate to adjust previously granted awards, to prevent dilution or
enlargement of the rights of the Participant, including any or all of the
following:

                  (i) adjustments in the aggregate number or kind of shares of
Common Stock which may be awarded under the Plan;

                  (ii) adjustments in the aggregate number or kind of shares of
Common Stock covered by awards already made under the Plan; or

                  (iii) adjustments in the purchase price of outstanding Stock
Options.

            (h) Assignability. No option shall be assignable or transferable
                -------------
except by will or by the laws of descent and distribution. During the lifetime
of an Optionee, an option shall be exercisable only by him, his legal
representative or his guardian.

            (i) Tax Withholding. The Optionee may remit to the Corporation at
                ---------------
the time of exercise of any option any taxes required to be withheld by the
Corporation under federal, state or local law as a result of the exercise of
such option or right. If the Optionee does not remit such taxes at the time of
exercise of an option, the Optionee will be deemed to have authorized the
Corporation to withhold such taxes in accordance with applicable law from any
regular cash compensation payable to him. If this Plan is qualified under 17
C.F.R. Section 240.16b-3 ("Rule 16b-3") under the Securities and Exchange Act of
1934, as amended (the "Exchange Act"), then any withholding shall comply with 17
C.F.R. Section 240.166-3(e).

            (j) Other Conditions. The option agreements authorized under the
                ----------------
Plan may contain such other provisions as the Committee shall deem advisable.

          --------------------------
Committee, designate a person or persons to receive, in the event of death, any
stock option to which the Optionee would then be entitled. Such designation will
be made upon forms supplied by and delivered to the Corporation and may be
revoked in writing. If a Participant fails to effectively designate a
beneficiary, then the Participant's estate will be deemed to be the beneficiary.

      12. Rights of Shareholder. No Participant shall have any rights as a
          ---------------------
shareholder with respect to any shares covered by a stock option until the date

or other employee at any time.

transactions under this Plan are intended to comply with all applicable
conditions of the Rule 16b-3 or its successors under the Exchange Act. To the
extent any provisions of the Plan or action by the Committee fail to so comply,
it shall be deemed null and void, to the extent permitted by law and deemed
advisable by the Committee.

      15. Options Continue as a Result of a Successor. The obligations of the
          -------------------------------------------
Corporation under the Plan shall be binding upon any organization which shall
succeed to all or substantially all of the assets of the Corporation, and the
term "Corporation," whenever used in the Plan, shall mean and include any such
organization after the succession.
