ITEM 3.        INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE

               Smith Micro Software, Inc. (the "Registrant") hereby incorporates
by reference into this Registration Statement the following documents previously
filed with the Securities and Exchange Commission (the "Commission"):

               (a)    The Registrant's Annual Report on Form 10-K for the fiscal
                      year ended December 31, 2000, filed with the Commission on
                      March 29, 2001;

               (b)    The Registrant's Quarterly Report on Form 10-Q for the
                      fiscal quarter ended March 31, 2000 filed with the
                      Commission on May 14, 2001; and

               (c)    The Registrant's Registration Statement No. 000-26536 on
                      Form 8-A filed with the Commission on July 31, 1995,
                      together with Amendment No. 1 filed with the Commission on
                      September 7, 1995, in which there is described the terms,
                      rights and provisions applicable to the Registrant's
                      outstanding Common Stock.

               All reports and definitive proxy or information statements filed
pursuant to Section 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of
1934, as amended (the "1934 Act") after the date of this Registration Statement
and prior to the filing of a post-effective amendment which indicates that all
securities offered hereby have been sold or which deregisters all securities
then remaining unsold shall be deemed to be incorporated by reference into this
Registration Statement and to be a part hereof from the date of filing of such
documents. Any statement contained in a document incorporated or deemed to be
incorporated by reference herein shall be deemed to be modified or superseded
for purposes of this Registration Statement to the extent that a statement
contained herein or in any subsequently filed document which also is deemed to
be incorporated by reference herein modifies or supersedes such statement. Any
such statement so modified or superseded shall not be deemed, except as so
modified or superseded, to constitute a part of this Registration Statement.

ITEM 4.        DESCRIPTION OF CAPITAL STOCK

               Inapplicable.

ITEM 5.        INTERESTS OF NAMED EXPERTS AND COUNSEL

               Inapplicable.

ITEM 6.        INDEMNIFICATION OF OFFICERS AND DIRECTORS

               Under Section 145 of the Delaware General Corporation Law, the
Registrant has broad powers to indemnify its directors and officers against
liabilities they may incur in such capacities, including liabilities under the
Securities Act of 1933, as amended (the "1933 Act"). The Registrant's Bylaws
(the "Bylaws") provide that the Registrant will indemnify its directors and
officers to the fullest extent permitted by Delaware law. The Bylaws require the
Registrant to advance litigation expenses in the case of stockholder derivative
actions or other actions, against an undertaking by the directors and officers
to repay such advances if it is ultimately determined that the directors and
officers are not entitled to indemnification. The Bylaws further provide that
rights conferred under such Bylaws shall not be deemed to be exclusive of any
other right such persons may have or acquire under any agreement, vote of
stockholders or disinterested directors, or otherwise. The Registrant believes
that indemnification under its Bylaws covers at least negligence and gross
negligence.


                                      II-1
   3

               In addition, the Registrant's Certificate of Incorporation (the
"Certificate of Incorporation") provides that the Registrant shall indemnify its
directors and officers if such persons acted (i) in good faith, (ii) in a manner
reasonably believed to be in or not opposed to the best interests of the
Registrant, and (iii) with respect to any criminal action or proceeding, with
reasonable cause to believe such conduct was lawful. The Certificate of
Incorporation also provides that, pursuant to Delaware law, no director shall be
liable for monetary damages for breach of the director's fiduciary duty of care
to the Registrant and its stockholders. This provision in the Certificate of
Incorporation does not eliminate the duty of care, and in appropriate
circumstances, equitable remedies such as injunctive or other forms of
non-monetary relief will remain available under Delaware law. In addition, each
director will continue to be subject to liability for breach of the director's
duty of loyalty to the Registrant for acts or omissions not in good faith or
involving intentional misconduct, for knowing violations of law, for actions
leading to improper personal benefit to the director, and for payment of
dividends or approval of stock repurchases or redemptions that are unlawful
under Delaware law. The provision also does not affect a director's
responsibilities under any other law, such as the federal securities laws or
state or federal environmental laws. The Certificate of Incorporation further
provides that the Registrant is authorized to indemnify its directors and
officers to the fullest extent permitted by law through the Bylaws, or any
agreement, vote of stockholders or disinterested directors, or otherwise.

               The Registrant obtained directors' and officers' liability
insurance in connection with its initial public offering.

               In addition, the Registrant has entered into agreements to
indemnify its directors in addition to the indemnification provided for in the
Certificate of Incorporation and Bylaws. These agreements will, among other
things, indemnify the Registrant's directors for certain expenses (including
attorneys fees), judgments, fines and settlement amounts incurred by such person
in any action or proceeding, including any action by or in the right of the
Registrant, on account of services by that person as a director or officer of
the Registrant, or as a director or officer of any subsidiary of the Registrant,
or as a director or officer of any other company or enterprise that the person
provides services to at the request of the Registrant.

ITEM 9.        UNDERTAKINGS

               A.     The undersigned Registrant hereby undertakes:

               (1) To file, during any period in which offers or sales are being
made, a post-effective amendment to this Registration Statement:


                                      II-2
   4

                (i) To include any prospectus required by Section 10(a)(3) of
the 1933 Act.

                (ii) To reflect in the prospectus any facts or events arising
after the effective date of the Registration Statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the Registration
Statement. Notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than 20 percent change in the
maximum aggregate offering price set forth in the "Calculation of Registration
Fee" table in the effective Registration Statement.

               (iii) To include any material information with respect to the
plan of distribution not previously disclosed in the Registration Statement or
any material change to such information in the Registration Statement; provided,
however, that clauses (1)(i) and (1)(ii) do not apply if the Registration
Statement is on Form S-8 and the information required to be included in a
post-effective amendment by those paragraphs is contained in periodic reports
filed with or furnished to the Commission by the Registrant pursuant to Section
13 or Section 15(d) of the 1934 Act that are incorporated by reference into the
Registration Statement.

               (2) That, for the purpose of determining any liability under the
1933 Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

               (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

               B.     The undersigned Registrant hereby undertakes that, for
purposes of determining any liability under the 1933 Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
1934 Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the 1934 Act) that is incorporated by
reference into the Registration Statement shall be deemed to be a new
Registration Statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

               C.     Insofar as indemnification for liabilities arising under
the 1933 Act may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the indemnification provisions summarized in Item 6,
or otherwise, the Registrant has been advised that in the opinion of the
Commission such indemnification is against public policy as expressed in the
1933 Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the 1933 Act and
will be governed by the final adjudication of such issue.

certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-8 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Aliso Viejo, State of California, on this 31st day of
May, 2001.
