PMA Capital Announces Pricing of its $50 Million
Monthly Income Senior Notes Offering

Philadelphia, PA, May 29, 2003 – PMA Capital Corporation (NASDAQ: PMACA) reported today that it has priced its previously announced $50 million offering of 8.50% monthly income senior notes due June 15, 2018. PMA Capital anticipates that the transaction will close on Thursday, June 5, 2003.

PMA Capital intends to use the net proceeds from the offering to repay the remaining $13 million of outstanding debt under its revolving credit facility, to increase the capital and surplus of its insurance subsidiaries, and for general corporate purposes.

The notes are general, senior unsecured obligations of PMA Capital and will rank equally in right of payment with all of its other existing and future senior unsecured indebtedness. The debentures bear interest at a rate of 8.50% per annum, payable monthly, beginning on June 15, 2003.

Ferris, Baker Watts, Incorporated served as the lead manager with Advest, Inc. and Sandler O’Neill & Partners, L.P. serving as co-managers. PMA Capital has granted the underwriters an option to purchase up to an additional $7.5 million principal amount of notes sold to cover over-allotments, if any.

This press release shall not constitute an offer to sell or the solicitation of an offer to buy any of the senior notes to be offered, nor shall there be any sale of senior notes in any state in which such offer, solicitation or sale would be unlawful. Offers for the senior notes will be made only by means of a prospectus (including a final prospectus supplement) forming a part of PMA Capital’s effective registration statement.
