This amendment to the Annual Report on Form 10K of ProAssurance, Corp. (the
"Registrant") for the year ended December 31, 2001 is filed to correct
typographical errors in the table included under the caption "Analysis of
Losses and Loss Adjustment Expense Reserve Development" in Item 1 of Part 1.

The "Cumulative net paid as of: Eight years later" amount for 1993 was reported
as $86,821; however, it should be $76,821.

The "Re-estimated net liability as of: One year later" amount for 1995 was
reported as $352,212; however, it should be $325,212.

The "Net re-estimated liability - latest" for 1997 was reported as $313,202;
however, it should be $323,202.

The "Gross cumulative redundancy" for 1996 was reported as $538,720; however,
it should be $238,720.

The "Gross cumulative redundancy" for 1999 was reported as $38,064; however, it
should be $48,097.

The section in Part 1, Item 1 entitled "Loss Reserve Development Table" is
restated in its entirety on the following pages.

                                       2

LOSS RESERVE DEVELOPMENT TABLE

         The following table includes information regarding the development of
the liability for unpaid losses and LAE of ProAssurance for the years ended
December 31, 1991 through 2001. The table includes losses and LAE on both a
direct and an assumed basis and is net of reinsurance recoverables:

    -    the line entitled "Losses and LAE Reserves, undiscounted and net of
         reinsurance recoverables" reflects the amount recorded as the reserve
         for liability for unpaid losses and LAE in the consolidated balance
         sheet at the end of each year (the "Balance Sheet Reserves");

    -    the section entitled "Cumulative net paid, as of" reflects the
         cumulative amounts paid as of the end of each succeeding year with
         respect to the previously recorded Balance Sheet Reserves;

    -    the section entitled "Re-estimated net liability as of" reflects the
         re-estimated amount of the liability previously recorded as Balance
         Sheet Reserves that includes the cumulative amounts paid and an
         estimate of additional liability based upon claims experience as of the
         end of each succeeding year (the "Net Re-estimated Liability");

    -    the line entitled "Net cumulative redundancy, (deficiency)" reflects
         the difference between the previously recorded Balance Sheet Reserve
         for each applicable year and the Net Re-estimated Liability relating
         thereto as of the end of the most recent fiscal year.

         The gross liability for losses and LAE before reinsurance, as reflected
on the balance sheet and re-estimated in each of the years since 1993, and the
reconciliation of the gross liability to amounts  net of reinsurance are
reflected below the table.

         Information presented in the following table is cumulative and,
accordingly, each amount includes the effects of all changes in amounts for
prior years. The table presents the development of ProAssurance's Balance Sheet
Reserves; it does not present accident year or policy year development data.
Conditions and trends that have affected the development of liabilities in the
past may not necessarily occur in the future. Accordingly, it may not be
appropriate to extrapolate future redundancies or deficiencies based on this
table. The information relating to subsidiaries other than MA-Alabama is limited
to the property and casualty reserves from their respective dates of
acquisition. ProAssurance does not discount its reserves.

(a)      Reflects reserves of Medical Assurance excluding Professionals Group
         reserves, which were acquired on June 27, 2001. Accordingly, the gross
         and net reserve development (reserves recorded at the end of the year,
         as originally estimated, less reserves re-estimated as of subsequent
         years) relates only to the operations of Medical Assurance and does
         not include Professionals Group.

(b)      Reflects combined reserves of Medical Assurance and Professionals
         Group as December 31, 2001.


                                      4



         Medical professional liability loss experience is volatile and
cyclical. Over the past twenty-five years, the industry has experienced several
periods of increasing claim frequency and severity, followed by periods of
relative stability. At other times, due to tort reform, favorable judicial
decisions, favorable economic conditions or other unknown factors, claim
frequency and/or severity have decreased. Malpractice claims generally require
an extended period of time to resolve, and in many jurisdictions, the average
life of a claim is five years or longer. The combination of changing conditions
and the extended time required for claim resolution result in a loss cost
estimation process that requires actuarial skill and good judgment, and such
estimates require periodic revision. Management believes it is prudent to
establish initial loss and loss expense reserves that are reasonable and are
based on historical experience as well as on facts and circumstances known at
the balance sheet date. To the extent that actual results deviate from
expectations, reserve estimates are subsequently adjusted and ultimate paid
losses and loss expenses are more or less than the original estimates.

         ProAssurance's loss and loss expense reserves developed favorably in
many prior years for several reasons. First, ProAssurance utilizes a rigorous
and disciplined approach to investigating, managing and defending claims. This
philosophy, especially in Alabama, has generally produced results that are
better than industry averages in terms of loss payments and the proportion of
claims closed without indemnity payment. Second, ProAssurance's volume of
business, while substantial, is not of a sufficient size to fully support the
projection process, thus ProAssurance's data is supplemented with
industry-based data. Ultimately, actual payments on these reserves have often
been less than originally projected, creating redundancies.

         Third, reserves established in the late 1980's and early 1990's were
strongly influenced by the dramatically increased frequency and severity
experienced by ProAssurance, and the industry as a whole, during the
mid-1980's. Some of these trends moderated, and in some cases, reversed, by the
late 1980's or early 1990's. However, the ability to recognize the improved
environment was delayed due to the extended time required for claims
resolution. When these trends moderated, the reserves established during those
periods proved to be redundant.

         Finally, ProAssurance believed that its overall loss experience would
be worse than that which was anticipated by many of its competitors. As a
result, ProAssurance prudently established accident year reserves, resulting in
accident year loss ratios in excess of 100% of earned premium. In some
instances, these loss ratios proved to be accurate, while in other cases,
experience has been better than expected and redundancies have developed.

         The professional liability legal environment has deteriorated once
again during the past several years. Beginning in 2000, ProAssurance recognized
adverse trends in claim severity, causing increased estimates of certain loss
liabilities. As a result, favorable development of prior year loss reserves
slowed during 2000 and some amount of adverse development occurred during 2001.
ProAssurance has addressed these trends through increased rates, stricter
underwriting and modifications to claims-handling procedures.

         In each year, ProAssurance has utilized a consistent approach in
establishing reserve levels. The actuarial methodologies utilized include
incurred loss development, paid loss development and frequency-severity
projections. These techniques are applied to the data and the resulting
projections are evaluated by management to establish a best estimate of
reserves.
