Dawson hereby acknowledges that:
|
|
should the Commission or the staff, acting pursuant to delegated authority, declare
the filing effective, it does not foreclose the Commission from taking any action with
respect to the filing; |
|
|
|
the action of the Commission or the staff, acting pursuant to delegated authority,
in declaring the filing effective, does not relieve Dawson from its full responsibility
for the adequacy and accuracy of the disclosure in the filing; and |
|
|
|
Dawson may not assert staff comments and the declaration of effectiveness as a
defense in any proceeding initiated by the Commission or any person under the federal
securities laws of the United States. |
