Agent shall, unless it shall have previously delivered the Seller’s Escrow
Shares to or upon the order of Seller pursuant to Section 5.1,  deliver to the
Company the Buyer’s Escrow Shares and the Stock Power for registration of

delivery of Reset Shares, a number of Post Split Shares equal to the number of
Seller’s Escrow Shares owned by Seller on the record date for, and at the
effective time of, the Reverse Stock Split and deposited with the Escrow Agent.

obligation under this Section 3, Buyer shall promptly deliver to the Company for
registration of transfer to Seller any additional Post Split Shares as shall be
required to discharge Buyer’s obligations under this Section 3 and the Company
shall promptly register such transfer and deliver to Escrow Agent one
certificate for such additional Reset Shares registered in the name of Seller.

date for such one for three Reverse Stock Split, Seller owns 150,000 Seller’s

Seller’s name in respect of the Seller’s Escrow Shares pursuant to the one for
three Reverse Stock Split,  shall receive 50,000 additional Post Split Shares
