                                EXPLANATORY NOTE

     We are amending our Report on Form 10-Q for the period ended December 31,
2002 to include information referred to in the certifications of our chief
executive officer and our chief financial officer that was inadvertently omitted
from the report as filed on February 14, 2003.

PART I. FINANCIAL INFORMATION

ITEM 4.  CONTROLS AND PROCEDURES

     Within the 90 days prior to the date of this report, we carried out an
evaluation, under the supervision and with the participation of our management,
including the Chairman, President and Chief Executive Officer and Senior Vice
President and Chief Financial Officer, of the effectiveness of the design and
operation of our disclosure controls and procedures pursuant to Exchange Act
Rule 13a-14. Based upon that evaluation, the Chairman, President and Chief
Executive Officer, and Senior Vice President and Chief Financial Officer have
concluded that our disclosure controls and procedures are effective.

     Such disclosure controls and procedures are controls and procedures
designed to ensure that all information required to be disclosed in our reports
filed under the Exchange Act is recorded, processed, summarized and reported
within the time periods set forth in applicable Securities and Exchange
Commission forms, rules and regulations. In addition, we have reviewed our
internal controls and have concluded that there have been no significant changes
in such internal controls or other factors that could significantly affect those
controls subsequent to the date of our review.
