Description of Capital Stock
Choice of Forum, page 11

1.     We note that your forum selection provision identifies the Court of
Chancery of the State
       of Delaware as the exclusive forum for certain litigation, including any
"derivative
       action." Please disclose whether this provision applies to actions
arising under the
       Securities Act or Exchange Act. In that regard, we note that Section 27
of the Exchange
       Act creates exclusive federal jurisdiction over all suits brought to
enforce any duty or
       liability created by the Exchange Act or the rules and regulations
thereunder, and Section
       22 of the Securities Act creates concurrent jurisdiction for federal and
state courts over all
       suits brought to enforce any duty or liability created by the Securities
Act or the rules and
       regulations thereunder. If the provision applies to Securities Act
claims, please also revise

         your prospectus to state that there is uncertainty as to whether a
court would enforce such
         provision and that investors cannot waive compliance with the federal
securities laws and
         the rules and regulations thereunder. If this provision applies to the
Securities Act, please
         revise your prospectus to include related risk factor disclosure.
        We remind you that the company and its management are responsible for
the accuracy
and adequacy of their disclosures, notwithstanding any review, comments, action
or absence of
action by the staff.
