Ladies and Gentlemen:

         With respect to the Registration Statement on Form SB-2 (the
"Registration Statement") being filed by ISNI.net, Inc. (the "Company") under
the Securities Act of 1933, as amended, relating to the registration of
7,161,000 common shares of the Company, $0.0001 par value (the "Shares"), we
advise you as follows:

         We are counsel for the Company and have participated in the preparation
of the Registration Statement. We have reviewed the Company's Certificate of
Incorporation, as amended to date, the corporate action taken to date in
connection with the Registration Statement and the issuance and sale of the
Shares, and such other documents and authorities as we deem relevant for the
purpose of this opinion.

         Based upon the foregoing, we are of the opinion that, upon compliance
with the Securities Act of 1933, as amended, and with the securities or "Blue
Sky" laws of the states in which the Shares are to be offered for sale, the
Shares will be validly issued, fully paid, and nonassessable.

         We consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of our name under the caption "Legal
Experts" in the prospectus included in the Registration Statement.


                                         Very truly yours,

                                         /s/ Porter, Wright, Morris & Arthur LLP

                                         Porter, Wright, Morris & Arthur LLP
