Richmond, VA, July 14, 2010 — Markel Corporation (NYSE – MKL) and Aspen Holdings, Inc. (doing business as FirstComp) announced today they have entered into a definitive agreement for the acquisition by Markel of Aspen, a privately held insurance group that provides workers’ compensation insurance and related services, principally to small businesses, in 31 states. Aspen, which is headquartered in Omaha, Nebraska, operates primarily through FirstComp Insurance Company, a Nebraska-domiciled insurance company; FirstComp Underwriters Group, Inc. and FirstComp Insurance Agency, Inc., which act as managing general agents; and REX, Inc., which operates as a wholesale intermediary.

Aspen’s subsidiaries collectively underwrite more than $300 million of gross written premium annually. They operate through a network of over 9,000 retail agents and have more than 500 employees based in Nebraska, Rhode Island, Nevada, California and Florida.

Following the acquisition, Aspen will continue to operate as a separate business unit, with Luke Yeransian, Aspen’s current chief executive officer, as president. The operating unit will be part of Markel’s specialty admitted segment, headed by Mike Crowley, Markel’s president and co-chief operating officer.

Subject to the terms of the merger agreement, Aspen’s shareholders will receive up-front consideration of approximately $135 million in cash plus the value relating to certain outstanding Aspen stock options at closing, as well as contingent value rights that may result in the payment of additional cash consideration depending, among other things, upon the development of Aspen’s loss reserves and loss sensitive profit commissions over time. The transaction is subject to customary closing conditions, including regulatory approvals and approval of Aspen’s shareholders, and is expected to close before year-end.

“This transaction presents an excellent opportunity for Markel to use its financial strength to allow Aspen to increase its penetration in the states where it currently operates, expand geographically and retain a greater share of the business it generates over time,” said Mike Crowley, Markel’s president and co-chief operating officer. “Aspen has developed a state-of-the-art technology platform enabling it to efficiently quote, bind and issue more than 100,000 policies annually. This platform can be leveraged to offer additional Markel Specialty product lines, and Aspen’s workers’ compensation expertise can be brought to bear to service current Markel customers.”

“Our technology, distribution, strong customer service ethic and underwriting discipline are a great fit with Markel,” said Luke Yeransian, Aspen’s chief executive officer. “The acquisition by Markel gives us an opportunity to match Markel’s financial strength with our extensive

distribution network and technology platform to continue to grow the workers’ compensation business. This combination also gives us the platform to expand into additional property and casualty product offerings. It will allow us to serve our agents and insureds even better and will give our employees a broader arena in which to fulfill their potential. Markel and Aspen share a great deal of respect and admiration for each other, and we are excited about the prospect of combining our talents with theirs.”

Markel Corporation markets and underwrites specialty insurance products and programs to a variety of niche markets. In each of these markets, the Company seeks to provide quality products and excellent customer service so that it can be a market leader. The financial goals of the Company are to earn consistent underwriting profits and superior investment returns to build shareholder value.
