Description of Stock Purchase Contracts and Stock Purchase Units, page 13

Please expand your discussion of the stock purchase units to provide a more comprehensive description of these securities, particularly with respect to the bundled debt securities. For example, in the event that the investor does not perform under the stock purchase agreement, clarify whether the investor will become the obligor or obligee of the debt.

Response:

As noted above, the Company has elected to remove stock purchase units from the Registration Statement. As such, all discussion regarding the stock purchase units has been removed from Amendment No. 2 to the Registration Statement.

3.	In addition, please provide us with an analysis as to whether you are required to register these third party obligations, and tell us whether you will obtain and file a legal opinion regarding any third party debt securities included in the stock purchase units.

Response:

Please see the response to Comment 2.

Exhibit 5.1

4.	We note your response to prior comment 5. Please have counsel clarify whether it is their intention to omit reported judicial decisions from the scope of their opinion regarding the laws of the State of New York and the Delaware General Corporation Law.

Response:

It is not our intention to omit reported judicial decisions regarding the laws of the State of New York and the Delaware General Corporation Law from the scope of our opinion. To clarify our intent we have revised our opinion to specifically include judicial decisions regarding the laws of the State of New York and the Delaware General Corporation Law.
