"Company"), a Nevada corporation,  in connection with the registration under the
Securities Act of 1933, as amended (the "Securities Act") of 6,481,334 shares of
the  Company's  Common  Stock  (the  "Shares"),   as  further   described  in  a
registration   statement  on  Form  SB-2/A   Pre-Effective   Amendment   No.  2,
Registration  Statement  No.  333-131946,  filed under the  Securities  Act (the
"Registration Statement") on May 5, 2006.

     In connection with this opinion, we have examined the following documents:

          with the Nevada Secretary of State;

     B.   Bylaws of the Company, as amended to date;

          pertaining to the Shares;

     D.   The Registration Statement; and

     E.   The  Prospectus/Information  Statement  constituting  a  part  of  the
          Registration Statement.

          certifying copies of certain documents and resolutions,  certifying as
          to certain other matters and dated May 5, 2006.

     In  addition,  we have  examined  such other  documents  as we have  deemed
necessary or appropriate as a basis for the opinions hereinafter expressed.

     As  to  certain  questions  of  fact,  we  have  relied,   without  further

assumed that the  signatures on all documents  examined by us are genuine,  that
all documents  submitted to us as originals are authentic and that all documents
submitted to us as copies or as facsimiles of copies or originals,  conform with
the originals, which assumptions we have not independently verified.

     Based upon the foregoing and the  examination of such legal  authorities as
we  have  deemed  relevant,  and  subject  to  the  qualifications  and  further
assumptions  set forth below, we are of the opinion that the Shares to which the
Registration  Statement and  Prospectus  relate are, or will be upon exercise of
the warrants,  validly issued,  duly authorized,  fully paid and  non-assessable
under the laws of the State of Nevada.

     The  foregoing  opinions  are  limited to the matters  expressly  set forth
herein and no opinion  may be implied or inferred  beyond the matters  expressly
stated.  We disclaim any  obligation to update this letter for events  occurring
after the date of this letter, or as a result of knowledge  acquired by us after
that date, including changes in any of the statutory or decisional law after the
date of this  letter.  We are  members  of the bar of the  State of  Nevada.  We
express no opinion as to the effect and application of any United States federal
law,  rule or  regulation  or any  securities  or blue  sky  laws of any  state,
including  the  State  of  Nevada.   We  are  not  opining  on,  and  assume  no
responsibility  as to, the  applicability to or the effect on any of the matters
covered  herein of the laws of any other  jurisdiction,  other  than the laws of
Nevada,  including  statutory  provisions  (except  to the  extent  specifically
limited herein),  applicable  provisions of the Nevada Constitution and reported
judicial decisions interpreting those laws, as presently in effect.

     We  hereby  consent  to the  use  of  this  opinion  as an  exhibit  to the
Registration  Statement  and to the  reference  to our  name  in the  Prospectus
constituting  a part of such  Registration  Statement  under the heading  "Legal
Matters."

                                  Very truly yours,

                                  WOODBURN and WEDGE
