     This letter will  constitute  an opinion  upon the  legality of the sale by
ActiVein,  Inc.,  a Delaware  corporation  (the  "Company"),  of up to 5,000,000
shares of its common stock and the sale by certain  shareholders  of the Company
of up to 275,000 shares of the Company's common stock, all as referred to in the

Exchange Commission.

     We have examined the Articles of Incorporation, the Bylaws, and the minutes
of the Board of Directors of the Company,  the  applicable  laws of the State of
Delaware and a copy of the Registration Statement.

     In our opinion:

     (i) the Company is authorized to sell the 5,000,000  shares mentioned above
and such shares,  when  issued,  will  represent  validity  authorized,  legally
issued, fully paid and non-assessable shares of the Company's common stock; and

     (ii) the shares to be sold by the Selling  Shareholders  have been  validly
authorized and legally issued and represent fully paid and non-assessable shares
of the Company's common stock.


                                           Very truly yours,

                                           HART & TRINEN
