     In connection with the above-captioned Registration Statement, the Company acknowledges that:

• should the Commission or the Staff, acting pursuant to delegated authority, declare the Registration Statement effective, it does not foreclose the Commission from taking any action with respect to the Registration Statement;

• the action of the Commission or the Staff, acting pursuant to delegated authority, in declaring the Registration Statement effective, does not relieve the Company from its full responsibility for the adequacy and accuracy of the disclosure in the Registration Statement; and

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

     Should you have any questions or comments regarding the foregoing, please contact me at (626) 803-5003.
