 * In accordance with Securities Exchange Act Release No. 39538 (January 12,
 1998), this filing reflects the securities beneficially owned by the
 Corporate and Investment Banking business group and the Corporate
 Investments business group (collectively, "CIB") of Deutsche Bank AG and
 its subsidiaries and affiliates (collectively, "DBAG"). This filing does
 not reflect securities, if any, beneficially owned by any other business
 group of DBAG. Consistent with Rule 13d-4 under the Securities Exchange Act
 of 1934 ("Act"), this filing shall not be construed as an admission that
 CIB is, for purposes of Section 13(d) under the Act, the beneficial owner
 of any securities covered by the filing. Furthermore, CIB disclaims
 beneficial ownership of the securities beneficially owned by (i) any client
 accounts with respect to which CIB or its employees have voting or
 investment discretion, or both, and (ii) certain investment entities, of
 which CIB is the general partner, managing general partner, or other
 manager, to the extent interests in such entities are held by persons other
 than CIB.

 ** Under the terms of a no-action letter issued by the SEC staff to Deutsche
 Bank AG on February 14, 2002, Deutsche Bank AG may report beneficial ownership
 for certain non-US subsidiaries on Schedule 13G pursuant to Rule 13d-1(b).
 The reporting person symbols provided in the Instructions to Schedule 13G have
 been used herein (see Question 12, "Type of Reporting Person") to classify
 the non-US subsidiaries eligible for 13G reporting under the SEC's no-action
 letter. In addition, the eligible non-US subsidiaries have been categorized
 herein (see Item 3) consistent with the business generally conducted by
 each such subsidiary.
