Footnotes

F1: Represents the weighted average sale price. The highest price at which shares were sold was $196.6788 and the lowest price at which shares were sold was $195.9964. Information regarding the number of shares sold at each separate price will be made available from the reporting person upon request by the SEC, the issuer or its shareholders.

F2: GATX Corporation's 401(k) plan is a unitized stock fund made up of company stock plus short term investments. Because the fund includes more than company stock, participants hold units of the fund rather than company shares of stock. The number of units held by a participant may vary depending on the performance of the company stock, the overall stock market, and the amount of short term investments in the fund. Such a variance has caused the value of the units in the reporting person's 401(k) fund to be reduced without any actual disposition of shares.
