                  Section 13 of the Securities Exchange Act of 1934 (the "1934

         (b)      The Registrant's Quarterly Reports on Form 10-Q for the fiscal
                  quarters ended July 26, 1996, October 25, 1996 and January 24,
                  1997 filed with the Commission on September 9, 1996, December
                  9, 1996 and March 7, 1997, respectively.

         (c)      The Registrant's reports on Form 8-K, filed with the 
                  Commission on September 9, 1996 and March 28, 1997,

         (d)      The Registrant's Registration Statement No. 00-27130 on Form
                  8-A filed with the Commission on November 1, 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 1934 Act after the date of
this Registration Statement and prior to the filing of a post-effective

         Section 317 of the California Corporations Code authorizes a court to

arising under the Securities Act of 1933, as amended, (the "1933 Act"). The

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 (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, and (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) shall not apply if
the information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed 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; and (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 Internet MiddleWare Corporation 1996
Long Term Equity Incentive Plan or upon the expiration of the special option
grants.

    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

                                      II-2.
   4
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 or controlling persons of
the Registrant pursuant to the indemnity provisions summarized in Item 6 or
otherwise, the Registrant has been informed 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.


                                      II-3.
