AIG Commercial Insurance

September 22, 2008

Dear Business Colleague,

Last week, Robert Schimek, EVP and CFO of AIG Property Casualty Group, and I had the opportunity to meet with many of you, our clients and brokers, to discuss the recent events at AIG, and explain the financial strength and advantages of the AIGCI companies. Thank you again for making your teams and clients available to share this important information. Your continued support is greatly appreciated.

In the coming weeks, the AIGCI senior management team will be traveling domestically and internationally to continue our meetings. While we would like to meet with each of you personally, we know that may not be possible. In case we are not able to meet, we offer the following archived webcast, which Rob and I hosted last Friday:

The webcast is also available at www.aig.com/commercialinsurance.

The presentation addressed the AIGCI companies' capital position and diverse business segments, with focus on the AIGCI companies':

Financial condition
Policyholder surplus
Investment portfolios

I would also point your attention to the following press release from the New York State Insurance Department: http://readme.readmedia.com/news/show/AIG-Policyholders-Should-Be-Careful-If-Approached-To-Replace-Policies/290957.

Thank you again for your support.
