The transaction is expected to close during the third quarter of 2010, subject to approval by PMA's shareholders, regulatory approvals and other customary closing conditions.

Speaking from PMA's headquarters, Vincent Donnelly, President and CEO, said that "We are pleased that we were able to reach this agreement with Old Republic, and we believe that this merger will have positive benefits to our shareholders, clients and employees. We expect that this transaction will enable our shareholders to realize greater long-term value than if we continued to operate as a stand-alone entity. We also believe that the additional financial strength and stability of a larger well diversified company will benefit our clients, employees and other stakeholders. Following the closing, we will continue to do business as the PMA Companies, and we will maintain our company headquarters in Blue Bell, Pennsylvania with our experienced leadership team and local service locations. We are excited about the opportunity that Old Republic presents for the continued profitable growth of our businesses."

In announcing the merger from Old Republic's Chicago headquarters, Al Zucaro.
Chairman and CEO stated that ". . . we are extremely pleased to welcome PMA's management and all of its associates to our family of companies. This merger is consistent with our long term strategic plan to grow our General Insurance business. The alliance of our two companies results in a well-capitalized insurance group appropriately positioned to take advantage of the many opportunities and synergies which will no doubt be available to us. The two companies share a commitment to conservative underwriting and a focus on select industries important to the American economy. We are convinced that the long-term orientation of the decision to effect this merger will at once provide greater scale, balance and diversification for our general insurance business, and produce enhanced future benefits for the combined shareholder groups."
