             INTRODUCTORY STATEMENT NOT FORMING PART OF PROSPECTUS

         On June 27, 2001, Medical Assurance, Inc. ("Medical Assurance") and
Professionals Group, Inc. ("Professionals Group") completed their consolidation
(the "Consolidation) and became wholly-owned subsidiaries of a newly formed
holding company named ProAssurance Corporation ("ProAssurance") pursuant to an
Agreement to Consolidate dated June 22, 2000 (the "Consolidation Agreement").
Upon consummation of the Consolidation, ProAssurance assumed all options
previously granted under Medical Assurance, Inc.'s Incentive Compensation Stock
Plan and Professionals Group, Inc.'s 1996 Long Term Stock Incentive Plan. Each
outstanding and unexercised option to purchase one share of Medical Assurance
common stock was converted into an option to purchase one share of ProAssurance
Common Stock at the same option price. Each outstanding and unexercised option
to purchase one share of Professionals Group common stock was converted into an
option to purchase 1.760 shares of ProAssurance Common Stock at an option price
to be determined by dividing the option price for the subject share of
Professionals Group common stock by the exchange ratio of 1.760. The shares of
ProAssurance Common Stock subject to the outstanding options were registered in
the Registration Statement of ProAssurance on Form S-4 (No. 333-49378) and are
not included in this Registration Statement.

         On September 27, 2001, the Board of Directors of ProAssurance
authorized the assumption of Medical Assurance's Incentive Compensation Stock
Plan by ProAssurance and amended the plan to expand the participants to
employees, advisors and consultants of ProAssurance and its subsidiaries; to
substitute ProAssurance Common Stock for Medical Assurance common stock as the
stock subject to the plan; and to change the name of the plan to "ProAssurance
Corporation Incentive Compensation Stock Plan." This Registration Statement
relates to 1,420,516 shares of ProAssurance Common Stock that are reserved for
issuance under the plan and that are not subject to outstanding options or
awards. The shares subject to this Registration Statement have been approved
for listing on the New York Stock Exchange.

ITEM 4.  DESCRIPTION OF SECURITIES

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

         Not applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         As permitted by Delaware law, the Registrant's certificate of
incorporation provides that the directors of the Registrant will not be held
personally liable for a breach of fiduciary duty as a director, except that a
director may be liable for (1) a breach of the director's duty of loyalty to
the corporation or its shareholders, (2) acts made in bad faith or which
involve intentional misconduct or a knowing violation of the law, (3) illegal
payment of


                                       3
<PAGE>


dividends under Section 174 of the Delaware General Corporation Law; or (4) for
any transaction from which the director derives an improper personal benefit.

         The by-laws of the Registrant provide that the Registrant will
indemnify any person involved in litigation brought by a third party or by or
in the right of the corporation by reason of the fact that he or she is or was
a director, officer, employee or agent of the corporation or is or was serving
at the request of the corporation as a director, officer, employee or agent of
another entity. The Registrant will only indemnify such a person if that person
acted in good faith and in a manner he or she reasonably believed to be lawful
and in the best interests of the corporation, except that the person will not
be entitled to indemnification in an action in which he or she is found to be
liable to the corporation unless the Court of Chancery deems indemnification
under these circumstances proper.

         The Registrant's certificate of incorporation further provides that if
Delaware law is amended to authorize corporate action further eliminating or
limiting the personal liability of directors, then the liability of a director
of the Registrant shall be eliminated or limited to the fullest extent
permitted by Delaware law, as so amended.

         The Consolidation Agreement provides that the Registrant, Medical
Assurance, and Professionals Group will jointly and severally indemnify, to the
fullest extent permitted by law, all persons serving or having served as
directors or officers of Medical Assurance or Professionals Group prior to the
completion of the Consolidation for any threatened or actual claim, action,
suit, proceeding, or investigation against them arising in whole or in part out
of, or pertaining to (1) the fact that he or she is or was a director or
officer of the Registrant, Medical Assurance or Professionals Group, or (2) the
Consolidation Agreement or any transaction contemplated by the Consolidation
Agreement. The indemnification obligations under the Consolidation Agreement
expire three years from June 27, 2001, the date the Consolidation was
completed.

         The Consolidation Agreement further provides that for a period of
three years after the Consolidation, the Registrant will use its best efforts
to maintain in effect directors' and officers' liability insurance covering
those persons who were covered by Professionals Group's directors' and
officers' liability insurance policy prior to the Consolidation in an amount
and scope at least as favorable as past policies covering Professionals Group's
directors and officers. This insurance coverage was obtained by the Registrant
promptly after completion of the Consolidation.

ITEM 9.  UNDERTAKINGS

         (a)      The undersigned Registrant hereby undertakes:

                  (1)      To file, during any period in which offers or sales
                           are being made, a post-effective amendment to this
                           registration statement to include any material
                           information with respect to the plan of distribution
                           not previously disclosed in the registration
                           statement or any material change to such information
                           in the registration statement;

                  (2)      That, for the purpose of determining any liability
                           under the Securities Act of 1933, each such
                           post-effective amendment shall be deemed to be a new
                           registration statement relating to the securities
                           offered therein, and the offering of such securities
                           at the time shall be deemed to be the initial bona
                           fide offering thereof; and

                  (3)      To remove from registration by means of a
                           post-effective amendment any of the securities being
                           registered which remain unsold at the termination of
                           the offering.

         (b)      The undersigned Registrant hereby undertakes that, for
                  purposes of determining any liability under the Securities
                  Act of 1933, each filing of the Registrant's annual report
                  pursuant to Section 13(a) or Section 15(d) of the Securities
                  Exchange Act of 1934 (and, where applicable, each filing of
                  an employee benefit plan's annual report pursuant to Section
                  15(d) of the Securities Exchange Act of 1934) that is
                  incorporated by reference in the registration statement shall
                  be deemed to be a new registration statement relating to the
                  securities offered herein, and the offering of such
                  securities at that time shall be deemed to be the initial
                  bona fide offering thereof.

         (c)      Insofar as indemnification for liabilities arising under the
                  Securities Act of 1933 may be permitted to directors,
                  officers and controlling persons of the Registrant pursuant
                  to the foregoing provisions, or otherwise, the Registrant has
                  been advised that in the opinion of the Securities and
                  Exchange Commission such indemnification is against public
                  policy as expressed in the Act and is, therefore,
                  unenforceable. In the event that a claim for indemnification
                  against such liabilities (other than the payment by the
                  Registrant of expenses incurred or paid by a director,
                  officer, or controlling person of the Registrant in the
                  successful defense of any action, suit or proceeding) is
                  asserted by such director, officer or controlling person in
                  connection with the securities being registered, the
                  Registrant will, unless in the opinion of its counsel the
                  matter has been settled by controlling precedent, submit to a
                  court of appropriate jurisdiction the question whether such
                  indemnification by it is against public policy as expressed
                  in the Act and will be governed by the final adjudication of
                  such issue.

INTRODUCTORY STATEMENT NOT FORMING PART OF PROSPECTUS

         On June 27, 2001, Medical Assurance, Inc. ("Medical Assurance") and
Professionals Group, Inc. ("Professionals Group") completed their consolidation
(the "Consolidation) and became wholly-owned subsidiaries of a newly formed
holding company named ProAssurance Corporation ("ProAssurance") pursuant to an
Agreement to Consolidate dated June 22, 2000 (the "Consolidation Agreement").
Upon consummation of the Consolidation, ProAssurance assumed all options
previously granted under Medical Assurance, Inc.'s Incentive Compensation Stock
Plan and Professionals Group, Inc.'s 1996 Long Term Stock Incentive Plan. Each
outstanding and unexercised option to purchase one share of Medical Assurance
common stock was converted into an option to purchase one share of ProAssurance
Common Stock at the same option price. Each outstanding and unexercised option
to purchase one share of Professionals Group common stock was converted into an
option to purchase 1.760 shares of ProAssurance Common Stock at an option price
to be determined by dividing the option price for the subject share of
Professionals Group common stock by the exchange ratio of 1.760. The shares of
ProAssurance Common Stock subject to the outstanding options were registered in
the Registration Statement of ProAssurance on Form S-4 (No. 333-49378) and are
not included in this Registration Statement.

         On September 27, 2001, the Board of Directors of ProAssurance
authorized the assumption of Medical Assurance's Incentive Compensation Stock
Plan by ProAssurance and amended the plan to expand the participants to
employees, advisors and consultants of ProAssurance and its subsidiaries; to
substitute ProAssurance Common Stock for Medical Assurance common stock as the
stock subject to the plan; and to change the name of the plan to "ProAssurance
Corporation Incentive Compensation Stock Plan." This Registration Statement
relates to 1,420,516 shares of ProAssurance Common Stock that are reserved for
issuance under the plan and that are not subject to outstanding options or
awards. The shares subject to this Registration Statement have been approved
for listing on the New York Stock Exchange.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

         Not applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         As permitted by Delaware law, the Registrant's certificate of
incorporation provides that the directors of the Registrant will not be held
personally liable for a breach of fiduciary duty as a director, except that a
director may be liable for (1) a breach of the director's duty of loyalty to
the corporation or its shareholders, (2) acts made in bad faith or which
involve intentional misconduct or a knowing violation of the law, (3) illegal
payment of

                                       3
dividends under Section 174 of the Delaware General Corporation Law; or (4) for
any transaction from which the director derives an improper personal benefit.

         The by-laws of the Registrant provide that the Registrant will
indemnify any person involved in litigation brought by a third party or by or
in the right of the corporation by reason of the fact that he or she is or was
a director, officer, employee or agent of the corporation or is or was serving
at the request of the corporation as a director, officer, employee or agent of
another entity. The Registrant will only indemnify such a person if that person
acted in good faith and in a manner he or she reasonably believed to be lawful
and in the best interests of the corporation, except that the person will not
be entitled to indemnification in an action in which he or she is found to be
liable to the corporation unless the Court of Chancery deems indemnification
under these circumstances proper.

         The Registrant's certificate of incorporation further provides that if
Delaware law is amended to authorize corporate action further eliminating or
limiting the personal liability of directors, then the liability of a director
of the Registrant shall be eliminated or limited to the fullest extent
permitted by Delaware law, as so amended.

         The Consolidation Agreement provides that the Registrant, Medical
Assurance, and Professionals Group will jointly and severally indemnify, to the
fullest extent permitted by law, all persons serving or having served as
directors or officers of Medical Assurance or Professionals Group prior to the
completion of the Consolidation for any threatened or actual claim, action,
suit, proceeding, or investigation against them arising in whole or in part out
of, or pertaining to (1) the fact that he or she is or was a director or
officer of the Registrant, Medical Assurance or Professionals Group, or (2) the
Consolidation Agreement or any transaction contemplated by the Consolidation
Agreement. The indemnification obligations under the Consolidation Agreement
expire three years from June 27, 2001, the date the Consolidation was
completed.

         The Consolidation Agreement further provides that for a period of
three years after the Consolidation, the Registrant will use its best efforts
to maintain in effect directors' and officers' liability insurance covering
those persons who were covered by Professionals Group's directors' and
officers' liability insurance policy prior to the Consolidation in an amount
and scope at least as favorable as past policies covering Professionals Group's
directors and officers. This insurance coverage was obtained by the Registrant
promptly after completion of the Consolidation.

                  securities at that time shall be deemed to be the initial
                  bona fide offering thereof.

         (c)      Insofar as indemnification for liabilities arising under the
                  Securities Act of 1933 may be permitted to directors,
                  officers and controlling persons of the Registrant pursuant
                  to the foregoing provisions, or otherwise, the Registrant has
                  been advised that in the opinion of the Securities and
                  Exchange Commission such indemnification is against public
                  policy as expressed in the Act and is, therefore,
                  unenforceable. In the event that a claim for indemnification
                  against such liabilities (other than the payment by the
                  Registrant of expenses incurred or paid by a director,
                  officer, or controlling person of the Registrant in the
                  successful defense of any action, suit or proceeding) is
                  asserted by such director, officer or controlling person in
                  connection with the securities being registered, the
                  Registrant will, unless in the opinion of its counsel the
                  matter has been settled by controlling precedent, submit to a
                  court of appropriate jurisdiction the question whether such
                  indemnification by it is against public policy as expressed
                  in the Act and will be governed by the final adjudication of
                  such issue.
