  "),
  entered into a nonbinding Letter of Intent (the "
  LOI
  ") with Joseph Petri and Peter Walstrom, individuals residing
  in the State of Florida (collectively the "

  "), providing for the Company's purchase from the Sellers'
  of certain convertible debt (the "

  of the Debt from Sellers to the Company and supplying $2,500,000.00 in new working capital for the operation of BDH. The LOI further
  contemplates the successful re-negotiation of certain BDH secured and unsecured liabilities prior to entering into a management
  agreement under which the Company will manage the operation of the Facility together with the Sellers as a step towards an eventual
  ownership of BDH.
  The
  foregoing description of the LOI does not purport to be complete and is qualified in its entirety by reference to the LOI, a copy
  of which is attached hereto as Exhibit 10.1 and incorporated herein by reference.
