HCC ESTIMATES FIRST QUARTER CATASTROPHE LOSSES AND SCHEDULES FIRST QUARTER 2010 EARNINGS RELEASE AND CONFERENCE CALL

HOUSTON (April 13, 2010) . . .

HCC Insurance Holdings, Inc. (NYSE: HCC) announced today that it estimates losses from first quarter catastrophes, which include the Chilean earthquake, the Haitian earthquake, and European windstorm Xynthia, to be approximately $20.0 million pretax and $13.0 million after-tax. These amounts include estimated losses and loss expenses net of reinsurance recoverable and also include estimated reinsurance reinstatement premiums. The estimated loss is primarily from the Chilean earthquake. HCC estimates the total after-tax loss will reduce the Company's first quarter earnings by approximately $0.11 per diluted share.

John N. Molbeck, Jr., HCC President and Chief Executive Officer, commented, "As we would expect in a catastrophe like the Chilean earthquake, we have potential losses in marine and energy as well as our property insurance and property treaty books. The amount of loss is within our expectations and within our reinsurance programs."
