Stockholder Communication Process

Process for Stockholder Communication with Board

Stockholders may communicate with the Board of Directors by regular mail at the following address:

Board of Directors—Stockholder Communication
P.O. Box 460256
San Antonio, Texas 78246-0256

All correspondence will be sent to the Chair of the Company's Nominating and Corporate Governance Committee. The Chair will determine which correspondence is to be circulated to one or more additional Board members.

The Company's practice is to schedule a Board meeting on the same day as the Annual Meeting of Stockholders. All Board members are encouraged to attend the Annual Meeting of Stockholders.
