                            DESCRIPTION OF AMENDMENT

         ProAssurance Corporation (the "Registrant") registered the issuance of
34,741,435 shares of its common stock (the "Registered Shares") pursuant to a
Registration Statement on Form S-4 (File No. 333-49378) originally filed with
the Securities and Exchange Commission on November 6, 2000. On June 27, 2001,
the Registrant issued 25,890,442 Registered Shares (the "Issued Shares") to the
former shareholders of Medical Assurance, Inc. ("Medical Assurance") and
Professionals Group, Inc. ("Professionals Group") pursuant to the consolidation
of Medical Assurance and Professionals Group under the ownership of the
Registrant as contemplated by an Agreement to Consolidate between Medical
Assurance and Professionals Group dated June 22, 2000. Since June 27, 2001,
holders of options previously granted under the Professionals Group 1996 Long
Term Stock Incentive Plan have exercised options with respect to 137,992
Registered Shares, and Registrant has filed Post-Effective Amendment No. 1 to
the Registration Statement on Form S-8 with respect to 789,970 Registered Shares
(collectively the "Option Shares") reserved for issuance pursuant to options
previously granted under the Medical Assurance, Inc. Incentive Compensation
Stock Plan and the Professionals Group, Inc. 1996 Long Term Stock Incentive
Plan, all of which options were assumed by Registrant pursuant to said Agreement
to Consolidate, effective June 27, 2001. There are 7,923,031 shares of common
stock of the Registrant (the "Unsold Shares") that will not be issued as Issued
Shares or Option Shares under the Registration Statement. Registrant paid a
registration fee in the amount of $27,680 in connection with the registration of
the Unsold Shares under the Registration Statement. The registration fee paid by
the Registrant with respect to the Unsold Shares will be used as an offset
against registration fees payable on securities to be registered in the future
by the Registrant pursuant to SEC Rule 457(p).
