FORWARD-LOOKING STATEMENTS Certain statements made by American Physicians Capital, Inc. during this presentation may constitute forward-looking statements within the meaning of the federal securities laws. When we use words such as "will," "should," "believes," "expects," "anticipates," "estimates" or similar expressions we are making forward-looking statements. While we believe any forward-looking statements we will make are reasonable, they are subject to risks and uncertainties, and actual results could differ materially. These risks and uncertainties include, but are not limited to, the following: increased competition could adversely affect our ability to sell our products at premium rates we deem adequate, which may result in a decrease in premium volume, a decrease in our profitability, or both; our reserves for unpaid losses and loss adjustment expenses are based on estimates that may prove to be inadequate to cover our losses; an interruption or change in current marketing and agency relationships could reduce the amount of premium we are able to write; if we are unable to obtain or collect on ceded reinsurance, our results of operations and financial condition may be adversely affected; our geographic concentration in certain Midwestern states and New Mexico ties our performance to the business, economic, regulatory and legislative conditions in those states; a downgrade in the A.M. Best Company financial strength rating of our insurance subsidiaries could reduce the amount of business we are able to write; changes in interest rates could adversely impact our results of operation, cash flows and financial condition; market illiquidity and volatility associated with the current financial crisis makes the fair values of our investments more difficult to estimate, and may have other unforeseen consequences that we are currently unable to predict; the unpredictability of court decisions could have a material adverse financial impact on our business operations; our business could be adversely affected by the loss of one or more of our key employees; the insurance industry is subject to regulatory oversight that may impact the manner in which we operate our business, our ability to obtain future premium rate increases, the type and amount of our investments, the levels of capital and surplus deemed adequate to protect policyholder interests, or the ability of our insurance subsidiaries to pay dividends to the holding company; our status as an insurance holding company with no direct operations could adversely affect our ability to meet our debt obligations and fund future cash dividends and share repurchases; legislative or judicial changes in the tort system may have adverse or unintended consequences that could materially and adversely affect our results of operations and financial condition; applicable law and certain provisions in our articles and bylaws may prevent and discourage unsolicited attempts to acquire our Company that may be in the best interest of our shareholders or that might result in a substantial profit to our shareholders; any other factors listed or discussed in the reports filed by APCapital with the Securities and Exchange Commission under the Securities Exchange Act of 1934. APCapital does not undertake, and expressly disclaims any obligation, to update or alter its statements whether as a result of new information, future events or otherwise, except as required by applicable law. 2
