NYMAGIC, INC. to Continue Writing Excess Workers' Compensation Through Midlands Management Company; Agreement with CRM Holdings Terminated.

NEW YORK -- NYMAGIC, INC. (NYSE: NYM) reported today that its wholly-owned subsidiary, New York Marine And General Insurance Company, will continue writing a book of excess workers' compensation insurance through Midlands Management Company ("MMC"), and that its previous reinsurance agreement with Twin Bridges, Ltd., a wholly-owned subsidiary of CRM Holdings, Ltd. ("CRMH"), had been terminated effective December 31, 2006.

A. George Kallop, NYMAGIC's President and Chief Executive Officer said, "The termination of our agreement with CRMH's subsidiary was anticipated. NYM entered into a program agreement with MMC on January 1, 2006, and a substantial amount of premium covering excess workers' compensation insurance has already been written through MMC and independent of CRMH since the first of this year. We expect that this line will continue to make a substantial contribution to net premiums written in 2007."

NYMAGIC, INC. is an insurance holding company whose property and casualty insurance subsidiaries specialize in writing ocean marine, inland marine and non-marine liability insurance, and whose agency subsidiaries specialize in establishing markets for such business. The Company maintains offices in New York, San Francisco and Chicago.
