              PROXY STATEMENT FOR ANNUAL MEETING OF SHAREHOLDERS
 
                               ----------------
 
  This Proxy Statement and form of proxy enclosed herewith, which are first
being mailed to shareholders on or about March 26, 1998, are furnished in
connection with the solicitation by the Board of Directors of Pennsylvania
Manufacturers Corporation (the "Company") of proxies to be voted at the Annual
Meeting of Shareholders (the "Annual Meeting") to be held at the Company's
principal executive offices located at The PMA Building, 380 Sentry Parkway,
Blue Bell, Pennsylvania 19422 on Monday, April 27, 1998, at 9 a.m., local
time, and at any adjournments thereof.
 
  Shares represented by proxies in the accompanying form, if properly signed
and returned, will be voted in accordance with the specifications made thereon
by the shareholders. Any proxy not specifying to the contrary will be voted
for the election of the nominees for director named in this Proxy Statement.
Any shareholder who signs and returns a proxy in the accompanying form may
revoke it at any time before it is voted by giving written notice of such
revocation to the Secretary of the Company or by attending the Annual Meeting
and voting in person.
 
  The cost of solicitation of proxies in the accompanying form will be borne
by the Company, including expenses in connection with preparing and mailing
this Proxy Statement. Such solicitation will be made by mail and may also be
made on behalf of the Company by the Company's regular officers, directors and
employees in person or by telephone or telegram. The Company, upon request
therefor, will also reimburse brokers or persons holding shares in their names
or in the names of nominees for their reasonable expenses in sending proxies
and proxy materials to beneficial owners.
 
  Only holders of Common Stock, $5.00 par value, ("Common Stock") and Class A
Common Stock, $5.00 par value, ("Class A Common Stock") of record as of the
close of business on March 12, 1998 will be entitled to notice of and to vote
at the Annual Meeting. As of the close of business on March 12, 1998, the
Company had outstanding 14,555,342 shares of Common Stock and 9,462,690 shares
of Class A Common Stock.
 
  On each matter to come before the Annual Meeting, each holder of Common
Stock will be entitled to cast ten votes for each share of Common Stock held,
and each holder of Class A Common Stock will be entitled to cast one vote for
each share of Class A Common Stock held. Therefore, a total of 155,016,110
votes will be entitled to be cast at the Annual Meeting.
 
  The holders of Common Stock and Class A Common Stock representing a majority
of the votes entitled to be cast at the Annual Meeting will constitute a
quorum. The holders of Common Stock and Class A Common Stock will vote
together without regard to class on all matters presented at the Annual
Meeting. Cumulative voting rights exist with respect to the election of
directors, which means that each shareholder has the right, in person or by
proxy, to multiply the number of votes to which he is entitled by the number
of directors of the class to be elected, and to cast the whole number of such
votes for one candidate or to distribute them among two or more candidates.
The four nominees for directors of the Class of 2001 who receive the highest
number of votes cast by the holders of Common Stock and Class A Common Stock
entitled to vote, voting together without regard to class, will be elected as
directors of the Company.

                 SECTION 16(A) BENEFICIAL REPORTING COMPLIANCE
 
  Section 16 of the Securities Exchange Act of 1934 (the "Exchange Act")
requires that the officers and directors of a corporation, such as the
Company, which has a class of equity securities registered under Section 12 of
the Exchange Act, as well as persons who own more than 10% of a class of
equity securities of such a corporation, file reports of their ownership of
such securities, as well as monthly statements of changes in such ownership,
with the corporation and the Securities and Exchange Commission. Based upon
written representations received by the Company from its officers and
directors, and the Company's review of monthly ownership changes filed within
the Company by its officers and directors during 1997, the Company believes
that all such filings required during 1997 were made on a timely basis, except
that Mr. McCarter inadvertently filed one report late relating to a conversion
of shares of Common Stock into Class A Common Stock.
 
                             ELECTION OF DIRECTORS
 
  The Company's Board of Directors consists of 13 members. Each director is
elected for a three-year term and until his successor has been duly elected.
The current three-year terms of the Company's directors expire in the years
1998, 1999 and 2000.
 
  Four directors of the Class of 2001 are to be elected at the Annual Meeting.
Unless otherwise instructed, proxy holders will vote the proxies received by
them for the election of the nominees named below. All of the nominees are
currently directors of the Company. If any nominee becomes unavailable for any
reason, it is intended that the proxies will be voted for a substitute nominee
selected by the Board of Directors. The Board of Directors has no reason to
believe that any of the nominees named will be unable to serve if elected. Any
vacancy occurring on the Board of Directors for any reason may be filled by
the Board of Directors for the unexpired term. The four nominees for Class of
2001 directors receiving the highest number of votes cast at the Annual
Meeting will be elected as directors. Votes withheld and broker non-votes are
not counted toward a nominee's total.
 
 
                                       5

 
 THE BOARD OF DIRECTORS RECOMMENDS THAT THE SHAREHOLDERS VOTE FOR EACH OF THE
                          NOMINEES IDENTIFIED BELOW.
 
  The names of the nominees for directors of the Class of 2001, and the
directors of the Classes of 1999 and 2000 who will continue in office after
the Annual Meeting until the expiration of their respective terms, together

  Pension Plans
 
  Under The PMC Pension Plan and The PMC Supplemental Executive Retirement
Plan, participants are entitled to benefits pursuant to the formula set forth
under such plans, without regard to the limits under Section 415 and Section
401(a)(17) of the Internal Revenue Code of 1986. The benefit is based upon the
accrued pension benefit for the participant at December 31, 1992 plus annual
accruals beginning January 1, 1993 equal to the sum of (i) 1.5% of the
participant's compensation for the applicable benefit year, consisting of
wages and commissions but excluding bonus, severance payments or other
supplementary payments, plus (ii) .3% of the participant's covered
compensation, consisting of the average of the participant's taxable wage base
in effect for each calendar year during the 35-year period ending the last day
of the calendar year in which the participant attains Social Security
retirement age. A maximum of 25 years of service is considered in calculating
the annual benefit payable upon normal retirement at normal retirement age.
Based upon this formula, the estimated annual benefits payable upon normal
retirement at age 65 for each person named in the Summary Compensation Table
are as follows: (i) Mr. Anton, $158,660; (ii) Mr. Smithson, $105,448; (iii)
Mr. Tirney, $50,349; and (iv) Mr. Donnelly, $40,924. Because Mr. Austin was
appointed as President of Caliber One Management Company in April 1997, he was
not a participant under these plans as of December 31, 1997. The amounts for
Mr. Anton and Mr. Smithson do not include other retirement payments that would
be provided pursuant to their respective employment agreements.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  The following directors constitute the current members of the Compensation
Committee of the Board of Directors: John W. Miller, Jr., L.J. Rowell, Jr. and
Edward H. Owlett. During 1997, James F. Malone III, A. John May and Edward H.
Owlett served as members of the Compensation Committee. Mr. Malone, Mr. May
and Mr. Owlett are or have been members of law firms that furnished legal
representation to the Company and its subsidiaries during 1997. In the opinion
of the Company's management, the amounts paid to such firms represented
reasonable charges for the services rendered and were as fair as the charges
would have been had such services been furnished by law firms unaffiliated
with any of the directors.
 
REPORT OF THE COMPENSATION COMMITTEE ON THE COMPENSATION OF EXECUTIVE OFFICERS
OF THE COMPANY FOR THE YEAR ENDED DECEMBER 31, 1997
 
  The Compensation Committee of the Board of Directors makes decisions
regarding the aggregate compensation of the Company's executive officers
consisting of base salary, cash bonuses and stock option awards. In 1997, the
Compensation Committee consisted of James F. Malone III, A. John May and
Edward H. Owlett, none of whom are employees of the Company or its
subsidiaries.
 
  In 1997, the Compensation Committee met three times to review and approve
the Company's compensation program for senior executive employees. The
Compensation Committee also independently administered the stock option plans
of the Company.
 
  The Compensation Committee has implemented compensation policies that are
intended to support the Company's overall objective of enhancing value for our
shareholders. All of the compensation policies are designed to align executive
compensation with the Company's long-term business objectives and performance
of the Company and to enable the Company to attract, retain and reward
executive officers whose leadership and contributions are essential to the
Company's long-term success. In order to achieve these objectives, the
Company's compensation program for executive officers is based on the
following principles:
 
 
                                      12

 
  . The Company pays base salary to executive officers that is reasonably
   competitive with comparable United States insurance and reinsurance
   companies.
 
  . The Company rewards executives for their leadership, strategic
   management, corporate performance and individual performance through
   discretionary cash bonuses.
 
  . The Company seeks to provide additional incentive to executive officers
   and to align their interests with the long-term interests of shareholders
   through the granting of stock options.
 
  . The Company seeks to compensate its executive officers on an equitable
   basis, taking into consideration each individual's degree of
   responsibility and contribution to the achievement of the Company's
   overall objectives.
 
  In 1997, compensation for the Company's executive officers consisted of
three key elements: base salary and benefits, discretionary annual cash bonus
and stock-based compensation. The Compensation Committee evaluated and
determined each element separately and collectively to ensure that the
executive officers were appropriately compensated in a manner that satisfies
the basic compensation principles described above. During 1997, the
Compensation Committee engaged an independent compensation consultant to
assist in evaluating the competitiveness of the Company's executive
compensation program to compensation paid by 18 peer companies in the
property-casualty insurance and reinsurance industries and a broader group of
insurance companies included in three published surveys.
 
 Base Salary
 
  In 1997, the President of the Company recommended to the Committee a base
salary for the executive officers, other than himself and the Chairman of the
Board. The base salary for each executive officer is set on the basis of the
Compensation Committee's evaluation of each executive officer's value to the
Company and with reference to the base salary levels in effect for comparable
positions in the reinsurance or property casualty industry, which is further
subject to adjustment based upon an executive's experience and performance.
Based upon its review of the companies it surveyed, the Compensation Committee
concluded that the base salaries that had been paid to the Company's executive
officers were generally below the competitive level of salaries paid by other
companies. Therefore, the Compensation Committee made appropriate adjustments
to the base salary paid to executive officers in order to be reasonably
competitive with the peer companies it surveyed.
 
 Cash Bonus
 
  Prior to 1997, the Company had not awarded any cash bonuses to its executive
officers other than Mr. Smithson. In 1997, Mr. Smithson recommended that a
cash bonus be paid to each of the Presidents of PMA Re and the Property and
Casualty Group and the Company's Chief Financial Officer based upon their
individual achievements for the year ended December 31, 1996 and their
contributions to the long-range objectives of the Company. The Compensation
Committee approved a cash bonus of $100,000 to Mr. Tirney, President of PMA
Re, in recognition of PMA Re's underwriting results, contribution to the
Company's net income, and growth in premiums for the year ended December 31,
1996. The Compensation Committee approved a cash bonus of $100,000 to Mr.
Donnelly, President of the Property and Casualty Group, in recognition of his
efforts during 1996 to focus the activities of the Property and Casualty Group
as a speciality workers' compensation carrier, and to institute measures to
reduce its operating expenses and improve its contribution to the Company's
net income. The Compensation Committee approved a $50,000 cash bonus to
Francis W. McDonnell, the Company's Chief Financial Officer, in recognition of
his role in restructuring the Company's credit facilities and holding company
operations. The Compensation Committee also approved a $250,000 employment
incentive cash bonus to Ronald S. Austin, President of Caliber One Management
Company, the Company's newly-established specialty insurance operation payable
in two installments of $150,000 in 1997 and $100,000 in 1998.
 
 
                                      13

 
 Stock Options
 
  The Compensation Committee administers the Company's stock option plans
which provide for the issuance of options to purchase up to an aggregate of
3,864,903 shares of Class A Common Stock, of which options to purchase
3,117,612 shares of Class A Common Stock were outstanding as of December 31,
1997. All of the Company's stock option plans have been previously approved by
the Company's Board of Directors and shareholders. The primary purpose of the
stock option plans is to provide additional incentive to executive officers
and other key employees to further the growth, development and financial
success of the Company and to align the option recipients' interests with
those of the Company's shareholders. The Compensation Committee has a policy
of considering annual grants under the stock option plans to executive
officers. In 1997, the Compensation Committee granted options to purchase
324,500 shares of the Class A Common Stock to key employees of the Company, of
which 118,000 options were granted to executive officers. In making grants,
the Compensation Committee considered the number of options remaining
available for grant under the stock option plans, the aggregate amount of
options previously granted and the amount of options previously granted to
each of the executive officers. All of the options granted in 1997 to the
executive officers were at exercise prices in excess of the fair market value
of the Class A Common Stock on the date of grant.
 
 Compliance with Internal Revenue Code Section 162(m)
 
  Section 162(m) of the Internal Revenue Code generally disallows a tax
deduction to public companies for compensation over $1 million paid to the
Company's Chief Executive Officer and the four other most highly compensated
executive officers. However, qualifying performance-based compensation is not
subject to the deduction limit if certain requirements are met. The Company
believes that Section 162(m) will not have any effect on the deductibility of
compensation of the executive officers named in the Summary Compensation Table
for 1997. The policy of the Compensation Committee is to structure the
compensation of the Company's executive officers to avoid the loss of
deductibility for any compensation, although Section 162(m) will not preclude
the Compensation Committee from awarding compensation in excess of $1 million
if it should be warranted in the future.
 
 Compensation of the Chief Executive Officer
 
  In May 1997, Mr. Smithson, previously President and Chief Operating Officer
of the Company since 1995, became President and Chief Executive Officer of the
Company. Mr. Anton, the previous Chief Executive Officer of the Company,
continues to serve as the Chairman of the Board of the Company.
 
  Mr. Anton's base salary of $700,000 was determined in accordance with the
minimum specified in his employment contract, which currently expires March
31, 2002, and is subject to automatic one-year extensions if Mr. Anton is re-
elected Chairman of the Board of the Company at each annual organizational
meeting of the Board of Directors. Mr. Anton did not receive any bonus or
stock option awards in 1997.
 
  Mr. Smithson has an employment contract with the Company which currently
expires March 31, 2000, and is subject to automatic one-year extensions if Mr.
Smithson is re-elected President of the Company at each annual organizational
meeting of the Board of Directors. The contract requires the Company to pay
Mr. Smithson a salary of not less than $670,000 per year. During 1997, the
Compensation Committee recommended to the Board of Directors, and the Board of
Directors approved, the payment of a base salary at an annual rate of $700,150
to Mr. Smithson. In establishing the base salary for Mr. Smithson, the
Compensation Committee used the same criteria as for the other executive
officers. The Compensation Committee determined Mr. Smithson's base salary
based upon its evaluation of his long-term contribution to the Company, his
strategic leadership, his stature in the insurance industry and his ongoing
value to the Company and its shareholders. The amount of base salary paid to
Mr. Smithson in 1997 was reasonably competitive with the base salaries paid to
the chief executive officers of the peer companies surveyed by the
Compensation Committee.
 
  In 1997, Mr. Smithson received a cash bonus of $350,000 in recognition of
his leadership of the Company, the continuing development of the Company's
reinsurance business, the restructuring of the Property and
 
                                      14

 
Casualty Group, Mr. Smithson's commitment to the Company and in order to bring
Mr. Smithson's total cash compensation to a competitive level for comparable
positions in the survey of companies reviewed by the Compensation Committee.
 
  The Compensation Committee also approved the award to Mr. Smithson of options
to purchase 40,000 shares of Class A Common Stock pursuant to the 1996 Equity
Incentive Plan at an exercise price of $17.00 per share, which was in excess of
the fair market value of the Class A Common Stock on the date of grant.

P/C") for the same period, and assumes that with respect to the Company's Class
A Common Stock, the S&P 500 and the S&P P/C, $100 was invested on July 31, 1997
and all dividends were reinvested.

                             CERTAIN TRANSACTIONS
 
  The Company's largest shareholder is PMA Foundation (the "Foundation"),
formerly known as Pennsylvania Manufacturers' Association, which is a not-for-
profit corporation qualified under Section 501(c)(6) of the Internal Revenue
Code and whose purposes include the promotion of the common business interests
of its members and the economic prosperity of the Commonwealth of
Pennsylvania. As of February 28, 1998, the Foundation owned 4,561,225 shares
of Common Stock, and 912,225 shares of Class A Common Stock, which entitle the
Foundation to cast 30.0% of the total number of votes available to be cast in
matters brought before the Company's shareholders. All of the members of the
Company's Board of Directors currently serve as the members of the
Foundation's Board of Trustees. Also, Frederick W. Anton III, Chairman and
former Chief Executive Officer of the Company, serves as President and Chief
Executive Officer of the Foundation. The Company and certain of its
subsidiaries provide certain administrative services to the Foundation for
which the Company and its affiliates receive reimbursement. Total
reimbursements in 1997 amounted to $34,000. The Foundation also leases its
Harrisburg, Pennsylvania headquarters facility from a subsidiary of the
Company under a monthly operating lease presently requiring rent payments of
$20,000 per month and reimburses a subsidiary of the Company for its use of
office space in the Blue Bell, Pennsylvania facility. Rent and related
reimbursements paid in 1997 to the Company's affiliates by the Foundation
amounted to $249,757.
 
  James F. Malone III, A. John May, Edward H. Owlett and Joseph H. Foster, who
are directors of the Company, are or have been members of law firms that
furnished legal representation to the Company and its subsidiaries during
1997. In the opinion of the Company's management, the amounts paid to such
firms represented reasonable charges for the services rendered and were as
fair as the charges would have been had such services been furnished by law
firms unaffiliated with any of the directors.
 
  The Company has provided demand loans to certain officers of the Company and
its subsidiaries, for the purpose of providing such officers with funds to
purchase Common Stock or Class A Common Stock. The loans are collateralized by
the Common Stock or the Class A Common Stock purchased by the officer and bear
interest at a rate of 6% per annum. The following table sets forth certain
information with respect to indebtedness of executive officers of the Company
during 1997 under such program:
