As previously indicated, please state clearly and unambiguously at the beginning of your discussion in the summary section that you currently have no products, customers or revenues. Further, on page 9, your statement that you will compete "in your current and proposed businesses" is unclear to the extent that you have no current operations. Please revise for clarification. RESPONSE: We concur with the Staff and have updated the summary section and page 9 to reflect that we have no product, customers or revenues. STAFF COMMENT 3: We note your revisions in response to prior comment 8 and we reissue our comment in part.
