                              STOCK OWNERSHIP PLAN

         Effective December 1, 1992, the Board of Directors of Mutual Assurance,
Inc. adopted the Mutual Assurance, Inc. Open Market Stock Purchase Plan (the
"Plan") to provide incentives to a broad base of employees of Mutual Assurance,
Inc. and its subsidiaries in connection with the purchase of the common stock of
Mutual Assurance, Inc. Following a corporate reorganization, MAIC Holdings, Inc.
assumed the sponsorship of the Plan. Effective August 31, 1995, the name of the
Plan was changed to the MAIC Holdings, Inc. Open Market Stock Purchase Plan,
and, effective on and after August 31, 1995, shares of the common stock of MAIC
Holdings, Inc. were purchased pursuant to the provisions of the Plan. Effective
June 21, 1996, the name of the Plan was changed to the MAIC Holdings, Inc.
Thrift Plan. Thereafter, the corporate name of MAIC Holdings, Inc. was changed
to Medical Assurance, Inc. Effective June 27, 2001, as a result of a corporate
reorganization, shares of the common stock of ProAssurance Corporation (the
"Corporation") were substituted for shares of Medical Assurance, Inc. under the
Plan. Effective January 1, 2002, the Corporation assumed the sponsorship of the
Plan, restated and amended the Plan to make certain changes and improvements
therein, and changed the name of the Plan to the ProAssurance Corporation Stock
Ownership Plan. Effective December 1, 2002, the Plan is being amended and
restated to change the method of matching employee contributions to the Plan.

                           from his compensation during such Participation
                           Period; or

                                    (B)      Lump sum Cash Deposits or Share
                           Deposits may be made only during the month of January

                  share purchases (if necessary), a Participant who is an
                  Executive Officer or Director of the Corporation may elect
                  only to make lump sum Cash Deposits or Share Deposits. No
                  payroll deductions shall be made under the Plan for any
                  Executive Officer or Director.

                           (iii)    The Corporation shall fund Grants with
                  respect to the Cash Deposits and Share Deposits made during a

         business day following the funding of the Grant, or (2) the earliest
         date on which shares of Common Stock are reasonably available for

         Accounts at the end of the prior Participation Period toward the
         purchase of such number of shares of Common Stock as can then be
         purchased in ordinary brokerage transactions in the public market. The
         Plan Administrator will allocate the shares so purchased (including
         fractional shares) to the Accounts as provided in paragraph 5 below and

                  short term obligations such as money market funds, savings
                  accounts and/or certificates of deposit, in which event

                           (ii)     Participant Shares Subaccounts. All Share
                  Deposits made by a Participant and all shares of Common Stock
                  purchased with funds from the Cash Subaccount of such
                  Participant shall be credited to the Participant Shares
                  Subaccount maintained for such Participant.

                  (a)      The Grant Shares allocated to a Participant shall
         become fully vested and shall not be subject to forfeiture upon the
         occurrence of the sooner of the following:

                           (i)      The Participant has been an Employee of a

                  (b)      The Grant Shares shall be transferred to the
         Participant Share Account of the Participant upon vesting, subject to
         the payment of federal and state withholding requirements. The Plan
         Administrator shall have the right to withhold such number of the Grant
         Shares as may be necessary to generate funds to pay federal and state
         withholding taxes. The Agent may cause the withheld shares to be sold
         in the public market for the account of the Participant and the
         proceeds of the sale shall be distributed to the Corporation to fund
         the payment of such withholding taxes.

         8.       DISTRIBUTION AND WITHDRAWAL OF SHARES.

                  (a)      Promptly after vesting of the Grant Shares, the Plan
         Administrator shall distribute to the Participant, or to an investment
         brokerage account owned by the Participant, from the Participant Shares
         Account (i) the vested Grant Shares and (ii) the Participant Shares
         purchased with Cash Deposits or delivered as a Share Deposit upon which
         the Company made the Grant used to purchase the vested Grant Shares.
         Until distributed as stated in this subparagraph (a), the shares of
         Common Stock held in the Participant Shares Account shall be subject to
         withdrawal in accordance with the provisions of subparagraph (b) below.

                  (b)      A Participant may withdraw the shares of Common Stock
         held in the Participant Shares Subaccount maintained for such
         Participant at any time. In the event that a Participant withdraws
         shares from his or her Participant Shares Account, the shares subject
         to withdrawal shall be taken from the shares that have been credited to
         the Participant Shares Account for the longest period of time in the
         inverse order that such shares were credited to the Participant Shares
         Subaccount. The withdrawal of any shares of Common Stock from a
         Participant's Participant Shares Subaccount shall be subject to the
         provisions of Section 9(b) hereof.

                  (c)      Grant Shares shall be distributed from the Grant
         Shares Account only upon vesting in accordance with paragraph 7 hereof
         or upon forfeiture in accordance with paragraph 9 hereof.

         9.       FORFEITURE OF SHARES.

                  (a)      In the event that a Participant ceases to be an
         Employee of a Participating Employer (for reasons other than those
         described in Section 7(a)(ii) above), all unvested Grant Shares
         credited to the Participant in a Grant Shares Account shall be
         forfeited and transferred to the Forfeiture Account.

                  (b)      In the event that a Participant withdraws shares of
         Common Stock from his or her Participant Shares Subaccount that were
         credited to said account, any unvested Grant Shares purchased with
         Grant Proceeds made with respect to the shares so withdrawn, determined
         in accordance with Section 8(f) hereof, shall be forfeited and
         transferred from the Participant's Grant Shares Account to the
         Forfeiture Account.

         10.      BENEFICIAL OWNERSHIP OF THE ACCOUNTS.

                  (a)      The Participant will be the beneficial owner of the
         Participant Shares held by the Plan Administrator for the Account of a
         Participant. The Participant will have the right to vote such shares at
         any meeting of the shareholders of the Corporation and will receive all
         communications addressed by the Corporation to its shareholders. All
         dividends (other than stock dividends) paid with respect to such shares
         shall, at the option of the Corporation, either be paid to the
         Participant or credited to the Cash Subaccount of a Participant. Stock
         dividends or stock splits paid with respect to Participant Shares shall
         be credited to the Participant Shares Subaccount. If the Corporation
         shall offer any subscription rights to its shareholders, the Plan
         Administrator shall to the extent it is able provide to each
         Participant who then has shares of Common Stock allocated to his
         Participant Shares Subaccount the right to exercise, sell, or assign,
         in accordance with the terms thereof, all subscription rights issued
         with respect to the shares in his Account and to receive any shares
         subscribed for, free from pledge.

                  (b)      The Corporation shall be the owner of the Grant
         Shares as treasury shares until they become vested. The Corporation may
         not vote, sell or withdraw any shares of Common Stock held in the Grant
         Shares Account. The Corporation shall have the right to withdraw shares
         of Common Stock held in the Forfeiture Account at any time free and
         clear of any claims of Participants under the Plan.

         11.      RIGHTS NOT TRANSFERABLE. No Participant shall be permitted to
sell, assign, transfer, pledge, or otherwise dispose of or encumber either his
right to participate in the Plan or his interest in any shares of Common Stock
being held by the Plan Administrator for the Account of a Participant prior to
the withdrawal or distribution thereof as herein contemplated. Except as
otherwise provided by law, the right and interest of a Participant under the
Plan shall not be liable for or subject to the debts, contracts or liabilities
of such Participant.

         12.      TERMINATION OR AMENDMENT OF PLAN. The Corporation reserves the
right to amend, modify, suspend, or terminate the Plan at any time without
notice, provided that no such amendment, modification, suspension, or
termination shall adversely affect, without the Participant's written consent,
any shares of Common Stock previously issued to the Participant.

         13.      COMPLIANCE WITH RULE 10b5-1. It is the intention of the
Corporation that provisions of the Plan be interpreted and administered so that
purchases and sales of Common Stock under the Plan will be transactions pursuant
to a contract, instruction or written plan that satisfies the affirmative
defense conditions of Rule 10b5-1(c) promulgated by the SEC under the 1934 Act.

         14.      PRIOR PARTICIPANT SHARES AND LOAN SHARES. The rights and
obligations of Participants and the Corporation under the Plan prior to December
1, 2002, shall not be modified as a result of this amendment and restatement of
the Plan. The rights and obligations of Participants with respect to Participant
Shares and Loan Shares purchased and pledged prior to December 1, 2002, shall be
governed by the terms of the Plan in effect as of the date of the purchase or
deposit of the Participant Shares and the funding of the Loans, except to the
extent the Plan has been amended to reflect the assumption of the Plan by the
Corporation.
