Explanation of Responses:

1. Pursuant to the Note Purchase Agreement, dated as of March 28, 2012, by and among the Issuer and SOK Partners LLC (the "SOK Note Purchase Agreement"), (i) the shares of Common Stock disclosed in Table I are an equity bonus issuable to SOK Partners LLC ("SOK Partners") under the SOK Note Purchase Agreement and (ii) the Issuer issued to SOK Partners the Convertible Promissory Grid Note (the "Grid Note") disclosed in Table II, the principal of which is convertible into Common Stock. The Grid Note may be converted into shares of Common Stock at any time at the option of SOK Partners. The Grid Note shall be converted into Common Stock if the Issuer effects certain qualified transactions where, as a result, the surviving entity has available at least $399,000 in additional cash and cash equivalents as a result of the transaction.

2. The Grid Note is convertible so long as any amount remains payable under the Grid Note. The Grid Note shall become due and payable on the earlier of (i) 150 days following March 28, 2012 and (ii) 30 days following a financing by the Issuer with gross proceeds of at least $399,000.

3. The Grid Note issued pursuant to the SOK Note Purchase Agreement may be converted into a number of shares of Common Stock equal to the then outstanding principal amount of the Grid Note divided by $0.065 (the "Grid Note Conversion Price"). The current outstanding principal of the Grid Note is $84,657. The Grid Note Conversion Price is subject to adjustment upon the occurrence of certain events, such as stock splits and issuance of stock for a consideration per share less than the Grid Note Conversion Price.
