The Company hereby acknowledges the following:

| • | the Company 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. |
Once the Registration Statement has been declared effective, please orally confirm that event with our counsel, Wilson Sonsini Goodrich & Rosati, P.C., by calling Dan Koeppen or Courtney Mathes at (858) 350-2393 or (858) 350-2320, respectively.
