Footnotes (2)

1. F1. 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.
2. F2. 33.33% of Stock Option granted may be exercised commencing 1 year from the date of the grant, an additional 33.33% commencing 2 years from the date of the grant and the remaining 33.34% commencing 3 years from the date of the grant.
