Application of the Safe Harbor of the Private Securities Litigation Reform Act of 1995:

This press release contains "forward-looking statements" within the meaning of the U.S. federal securities laws. These statements are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include all statements that do not relate solely to historical or current facts, and can be identified by the use of words such as "expect," "intend," "plan," "believe," "project," "anticipate," "seek," "will," "estimate," "may," "continue," and similar expressions of a future or forward-looking nature.

All forward-looking statements rely on a number of assumptions concerning future events and are subject to a number of uncertainties and other factors, many of which are outside the Company's control that could cause actual results to differ materially from such statements. Important events that could cause the actual results to differ include, but are not limited to: the impact of acts of terrorism and acts of war and related legislations; the possibility of greater frequency or severity of or unanticipated losses from natural or man-made catastrophes, including Hurricanes Katrina and Rita

and the New Orleans Flood; evolving interpretive issues with respect to coverage as a result of Hurricanes Katrina and Rita and the New Orleans Flood; the level of inflation in repair costs due to limited availability of labor and materials after catastrophes, the effectiveness of the Company's loss limitation methods; changes in the availability, cost or quality of reinsurance or retrocessional coverage; the loss of key personnel; a decline in the operating subsidiaries' ratings with Standard & Poor's, A.M. Best or Moody's; changes in general economic conditions; increased competition on the basis of pricing, capacity, coverage terms or other factors; decrease in demand for the Company's insurance or reinsurance products and cyclical downturn of the industry; changes in governmental regulation or tax laws in the jurisdictions where the Company conducts business; the total industry losses resulting from Hurricanes Katrina and Rita and the New Orleans Flood; the actual number of the Company's insureds incurring losses from these storms; the limited actual loss reports received from the Company's insureds to date; the preliminary nature of possible loss information received by brokers to date on behalf of cedants; the Company's reliance on industry loss estimates and those generated by modeling techniques; the impact of these storms on the Company's reinsurers; the amount and timing of reinsurance recoverables and reimbursements actually received by the Company from its reinsurers; the overall level of competition, and the related demand and supply dynamics as contracts come up for renewal. For a more detailed description of these uncertainties and other factors, please see the "Risk Factors" section in Aspen's Current Report on Form 8-K dated October 4, 2005 and its Annual Report on Form 10-K for the year ended December 31, 2004, filed with the U.S. Securities and Exchange Commission on March 14, 2005.
