Ladies and Gentlemen:

     We have acted as counsel to Semotus Solutions, Inc., a Nevada corporation
(the "Company"), in connection with the preparation and filing with the
Securities and Exchange Commission of a Registration Statement on Form S-3 (the
"Registration Statement"), pursuant to which the Company is registering under
the Securities Act of 1933, as amended, 737,036 shares (the "Shares") of its
outstanding common stock, $.01 par value per share (the "Common Stock"). The
Shares are being sold by the selling stockholders identified in the Registration
Statement. This opinion is being rendered in connection with the filing of the
Registration Statement.

     In connection with this opinion, we have examined the Company's Articles of
Incorporation and By-Laws, both as currently in effect; such other records of
the corporate proceedings of the Company as we have deemed relevant; and the
Registration Statement and the exhibits thereto.

     In our examination, we have assumed the genuineness of all signatures, the
legal capacity of natural persons, the authenticity of all documents submitted
to us as originals, the conformity to original documents of all documents
submitted to us as certified, photostatic, facsimile or electronic copies and
the authenticity of the originals of such copies.

       Based upon the foregoing, we are of the opinion that the Shares have been
   duly and validly authorized and issued by the Company, and are fully paid and
   non-assessable shares of the Company's Common Stock.

       Our opinion is limited to the laws of the State of California, corporate
   laws of the State of Nevada and the federal laws of the United States of
   America, and we express no opinion with respect to the laws of any other
   jurisdiction. No opinion is expressed herein with respect to the
   qualification of the Shares under the securities or blue sky laws of any
   state or any foreign jurisdiction.

       The foregoing opinion is rendered as of the date hereof. We assume no
   obligation to update such opinion to reflect any facts or circumstances which
   may hereafter come to our attention or changes in the law which may hereafter
   occur. We understand that you wish to file this opinion as an exhibit to the
   Registration Statement, and we hereby consent thereto. We hereby further
   consent to the reference to us under the caption "Legal Matters" in the
   prospectus included in the Registration Statement. In giving this consent, we
   do not thereby admit that we are within the category of persons whose consent
   is required under Section 7 of the Securities Act or the Rules and
   Regulations of the Commission.
