HOUSTON, July 13, 2006 (PRIMEZONE) -- HCC Insurance Holdings, Inc. (NYSE:HCC) announced today that the Company had acquired G.B. Kenrick & Associates, Inc. for an undisclosed cash consideration.

Kenrick, formed in 1985, is an insurance underwriting agency located in Auburn Hills, Michigan, and is recognized as one of the premier underwriters of municipal insurance.

Stephen L. Way, Chairman and Chief Executive Officer of HCC, stated, "Dave and Rick helped write the book on municipal insurance and we could not have a better introduction to this new line of business for HCC."

Dave Kensler, commenting on the transaction, said, "We are very excited about our future with HCC, who will provide the capital and resources necessary for us to expand our operations into other states, while maintaining the customary high level of service to our customers and our important existing insurance relationships."

Following the acquisition, Kenrick will operate independently and expects to double its business to more than $100 million premium in the next few years. Reporting to the premier HCC underwriting agency, PIA, in Mt. Kisco, New York, Kenrick will immediately become an important part of PIA's expanding agency operations.
