RE:  FORM SB-2 REGISTRATION STATEMENT

- -------------------------------------------------------------------------------

Ladies and Gentlemen:

      We  are  rendering  this  opinion  in  connection  with  the Registration
Statement on Form SB-2 filed by Echelon Acquisition Corp. Inc. (the  "Company")
with  the Securities and Exchange Commission under the Securities Act of  1933,
as amended,  on  May 12, 2006 (such Registration Statement as amended from time
to  time  is  referred   to   herein  as  the  "Registration  Statement").  The
Registration Statement relates  to  the  registration  of  55,476,000 shares of
common stock of the Company which may be offered for resale  by certain parties
listed  therein  (such  shares  are  referred  to  herein as the "Shares").  We
understand hat the Shares are to be offered and sold in the manner described in
the Registration Statement.

     We have acted as your counsel in connection with  the  preparation  of the
Registration  Statement  and  are  familiar  with  the proceedings taken by the
Company in connection with the resale of the Shares.  We have examined all such
documents as we consider necessary to enable us to render this opinion.

     Based upon the foregoing, we are of the opinion that  the Shares have been
duly authorized, validly issued, fully paid and non-assessable.

      We  hereby  consent  to the filing of this opinion as an exhibit  to  the
Registration Statement and to  the  reference to our firm under "Legal Matters"
in the Registration Statement.

Very truly yours,

King & Wood
