Dear Ms. Thompson:

With respect to your letter dated September 7, 2011, regarding your review of our filings, you request a response to the respective comments within 10 business days or for us to advise of when we would provide a response. Pursuant to my conversation yesterday with Ms. Sondra Snyder, I am writing to request additional time to provide our responses. Due primarily to travel schedules of certain key individuals, I would appreciate an extension for our response until September 30, 2011.

Thank you for your consideration.

Sincerely,
/s/ Ted Timmermans
