All of the Shares are to be issued by the Company (a) as compensation to Investor Resource Services, Inc. for certain services being rendered to the Company and (b) upon exercise of warrants issued to other parties providing services to the Company, and once issued may be offered for sale for the benefit of the selling shareholders named in the Registration Statement.
