(1) Morgan Stanley may be deemed to beneficially own 2,804 shares of Common Stock (the "Additional Shares") held by its operating units (collectively, the "MS Reporting Units"). In accordance with Securities and Exchange Commission Release No. 34-39538 (January 12, 1998) (the "Release"), this filing reflects the securities beneficially owned by the MS Reporting Units of Morgan Stanley and its subsidiaries and affiliates (collectively, "MS Group"). This filing does not reflect securities, if any, beneficially owned by any affiliates or operating units of MS Group whose ownership of securities is disaggregated from that of the MS Reporting Units in accordance with the Release. Neither the filing of this Form 3 nor any of its contents shall be deemed to constitute an admission by MS Group that it is the beneficial owner of any of such Additional Shares beneficially owned by (i) any client accounts with respect to which the MS Reporting Units or their employees (continued in footnote 2)
(2) have voting or investment discretion, or both, and (ii) certain investment entities of which the MS Reporting Units act as the general partner, managing general partner or other manager, to the extent interests in such entities are held by persons other than the MS Reporting Units, for purposes of Section 16 of the Exchange Act, or for any other purpose, and such beneficial ownership is expressly disclaimed.
 
Remarks:
Morgan Stanley and Mr. Hanlin Chen may be considered members of a group beneficially owning more than 10% of the Common Stock for purposes of Rule 16a (1) under the Securities Exchange Act of 1934. Neither the filing of this Form 3 nor any of its contents shall be deemed to constitute an admission by Morgan Stanly that it is the beneficial owner of any of Common Stocks for purposes of Section 16 of the Exchange Act, or for any other purpose, and such beneficial ownership is expressly disclaimed.
