ITEM 4: OWNERSHIP The securities reported on herein are beneficially owned by one or more open-end investment companies or other managed accounts which are advised or sub-advised by Waddell & Reed Investment Management Company ("WRIMCO"), an investment advisory subsidiary of Waddell & Reed, Inc. ("WRI"). WRI is a broker-dealer and underwriting subsidiary of Waddell & Reed Financial Services, Inc., a parent holding company ("WRFSI"). In turn, WRFSI is a subsidiary of Waddell & Reed Financial, Inc., a publicly traded company ("WDR"). The investment advisory contracts grant WRIMCO all investment and/or voting power over securities owned by such advisory clients. The investment sub-advisory contracts grant WRIMCO investment power over securities owned by such sub-advisory clients and, in most cases, voting power. Any investment restriction of a sub-advisory contract does not restrict investment discretion or power in a material manner. Therefore, WRIMCO may be deemed the beneficial owner of the securities covered by this statement under Rule 13d-3 of the Securities Exchange Act of 1934 (the "1934 Act"). WRIMCO, WRI, WRFSI and WDR are of the view that they are not acting as a "group" for purposes of Section 13(d) under the 1934 Act. Indirect "beneficial ownership" is attributed to the respective parent companies solely because of the parent companies' control relationship to WRIMCO.
