2. the action of the Commission or the Staff, acting pursuant to delegated authority, in declaring the filing effective, does not relieve the Company from its responsibility for the adequacy and accuracy of the disclosure in this filing; and

3. the Company may not assert this action as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States.
