Dear Sirs:

         You have requested our opinion with respect to certain matters in
connection with the filing by Franklin Telecommunications Corp. (the "Company")
of a Registration Statement on Form S-3 (the "Registration Statement") with the
Securities and Exchange Commission, covering the registration of the resale of
up to 10,491,538 shares of the Company's Common Stock, without par value (the
"Shares").

         In connection with this opinion, we have examined and relied upon the
Registration Statement, the Company's Amended and Restated Articles of
Incorporation and Amended and Restated Bylaws, the Warrants, and the originals
or copies certified to our satisfaction of such records, documents,
certificates, memoranda and other instruments as in our judgment are necessary
or appropriate to enable us to render the opinion expressed below. We have
assumed the genuineness and authenticity of all documents submitted to us as
originals, the conformity to originals of all documents submitted to us as
copies thereof and the due execution and delivery of all documents where due
execution and delivery are a prerequisite to the effectiveness thereof.

         On the basis of the foregoing, and in reliance thereon, we are of the
opinion that the Shares, when sold and issued in accordance with the
Subscription Agreement, as amended, and the Warrants, are or will be validly
issued, fully paid, and nonassessable shares of Common Stock of the Company.

         We consent to the filing of this opinion as an exhibit to the
Registration Statement.


                                               Very truly yours,

                                               /s/ Haddan & Zepfel LLP
                                               ---------------------------------
