                            EXHIBIT A


This Exhibit lists the entities affiliated with State Farm Mutual
Automobile Insurance Company ("Auto Company") which might be deemed to
constitute a "group" with regard to the ownership of shares reported
herein.

Auto Company, an Illinois-domiciled insurance company, is the parent
company of multiple wholly owned insurance company subsidiaries,
including State Farm Life Insurance Company, and State Farm Fire and
Casualty Company.  Auto Company is also the parent company of State
Farm Investment Management Corp. ("SFIMC"), which is a registered
transfer agent under the Securities Exchange Act of 1934 and a
registered investment advisor under the Investment Advisers Act of
1940.  SFIMC serves as transfer agent and investment adviser to State
Farm Associates' Funds Trust, State Farm Variable Product Trust, and
State Farm Mutual Fund Trust, three Delaware Business Trusts that are
registered investment companies under the Investment Company Act of
1940.  Auto Company also sponsors two qualified retirement plans for
the benefit of its employees, which plans are named the State Farm
Insurance Companies Employee Retirement Trust and the State Farm
Insurance Companies Savings and Thrift Plan for U.S. Employees
(collectively the "Qualified Plans").

As part of its corporate structure, Auto Company has established an
Investment Department.  The Investment Department is directly or
indirectly responsible for managing or overseeing the management of
the investment and reinvestment of assets owned by each person that
has joined in filing this Schedule 13G.  Moreover, the Investment
Department is responsible for voting proxies or overseeing the voting
of proxies related to issuers the shares of which are held by one or
more entities that have joined in filing this report.  Each insurance
company included in this report and SFIMC have established an
Investment Committee that oversees the activities of the Investment
Department in managing the firm's assets.  The Trustees of the
Qualified Plans perform a similar role in overseeing the investment of
each plan's assets.

Pursuant to Rule 13d-4 each person listed in the table below
expressly disclaims "beneficial ownership" as to all shares as to
which such person has no right to receive the proceeds of sale of the
security and disclaims that it is part of a "group".
