Re:  LocatePLUS  Holdings  Corporation  Common  Stock  -  SEC  Form  SB-2  -
      Common  Stock  issued  to  Dutchess  Private  Equities  Fund  II,  LP

Dear  Sirs:
     I am providing this opinion to you in connection with the issuance of up to
4,750,000  shares of Common Stock, par value $0.01 per share ( the "Shares" ) of
LocatePLUS  Holdings  Corporation  (the  "Company"  )  covered by a Registration
Statement  on  Form  SB-2  to  be  filed  with  the U.S. Securities and Exchange
Commission  covering  the  Shares,  as  follows:
- -     Up  to 3,500,000 Shares pursuant to an Investment Agreement dated December
29,  2005  ( the "Investment Agreement") and Registration Rights Agreement dated
December  29, 2005 (the "Registration Rights Agreement") between the Company and
Dutchess  Private  Equities  Fund  II,  LP  ("Dutchess").
- -     Up  to  300,000  Shares  to  be  issued  upon  conversion  of a $1,500,000
Debenture  dated  December  29, 2005 ( the "Debenture") issued by the Company to
Dutchess.
- -     200,000  Shares  issued  to  Dutchess  in  connection  with  the  above
transactions.
- -     Up  to  750,000 Shares to be issued on exercise of a Common Stock Purchase
Warrant  dated  December  29,  2005  (  the  "Warrant") issued by the Company to
Dutchess.
     In  connection  with  this  opinion I have examined copies of the following
documents represented by officers of the Company to be genuine and in full force
and  effect:
- -     Articles  of  Organization
- -     By-Laws
- -     The  Investment  Agreement
- -     Registration  Rights  Agreement
- -     The  Debenture
- -     The  Warrant
- -     Votes  of  the Board of Directors of the Company authorizing the execution
of  the  above-referenced documents and the issuance of the Shares out of shares
of  Common  Stock  reserved  for  the  purpose.

     Based  solely  upon  the  foregoing  and  upon  discussions with authorized
officers  of the Company I am of the opinion that the issuance of the Shares has
been  duly  authorized and that, upon exercise of the rights and pursuant to the
terms  and  conditions  of  the  Investment  Agreement,  the Registration Rights
Agreement,  the Debenture and the Warrant, the Shares issued will have been duly
authorized, validly issued, fully paid and non-assessable, subject to the rights
of  creditors  and  other  limitations  on  issuance  under  state  law.

     I  consent  to the inclusion of this letter as an Exhibit to a Registration
Statement  on  Form  SB-2  to  be  filed  with  the U.S. Securities and Exchange
Commission  covering  the  Shares.
