  iv. AVDU acknowledges that the sources of technologies represented by UTEK are 3rd party research institutions for which UTEK does not control whether the technology will be shown to other parties by the licensor.

  v. At AVDU's request, UTK will prepare, and compile additional information regarding the technology acquisition opportunities for AVDU.

  vi. At AVDU's request and upon mutual agreement between AVDU and UTK, UTK will negotiate and seek to acquire a license to the requested technology for subsequent sale to and acquisition by AVDU.

a. In arms length negotiation with the technology developer, UTK will seek to acquire the license to the technology through one of its subsidiaries.

The consideration to be paid by AVDU to UTK will be based upon a markup to the value of the license and other assets in the subsidiary as determined by UTK and agreed to by both parties.

b. Should AVDU decide not to proceed in the acquisition of the technology/company as described above, then AVDU shall be prohibited from acquiring the technology/company either directly or indirectly, from the technology/company developer for a period of 24 months following the termination of this Strategic Alliance Agreement.

UTK will then seek to provide a term sheet to AVDU outlining the consideration to be paid by AVDU for the acquisition of this technology. UTK shall transfer this subsidiary to AVDU in a stock for stock exchange under an Agreement and Plan of Acquisition.
