               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT


Item 3.     Incorporation of Documents by Reference

            YieldUP International Corporation, (the "Company") hereby
incorporates by reference in this registration statement the following
documents:

            (a) The Company's latest annual report on Form 10-KSB filed pursuant
to Sections 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), containing audited financial statements for the Company's
latest fiscal year ended December 31, 1995 as filed with the Commission on March
28, 1996.

            (b) All other reports filed pursuant to Section 13(a) or 15(d) of
the Exchange Act since the end of the fiscal year covered by the registrant
document referred to in (a) above including:

                (1)  Report on Form 10-QSB filed with the Commission on 4/30/96

                (2)  Report on Form 10-QSB filed with the Commission on 8/7/96

                (3)  Report on Form 10-QSB filed with the Commission on 10/31/96

            (c) The description of the Company's Common Stock contained in the
Company's Registration Statement on Form 8-A filed under the Exchange Act,
including any amendment or report filed for the purpose of updating such
description.

            All documents subsequently filed by the Company pursuant to Sections
13(a), 13(c), 14 and 15(d) of the Exchange Act, prior to the filing of a
post-effective amendment to this registration statement which indicates that all
securities offered hereby have been sold or which deregisters all securities
remaining unsold, shall be deemed to be incorporated by reference in this
registration statement and to be a part hereof from the date of filing of such
documents.

Item 4.     Description of Securities

            The class of securities to be offered is registered under Section 12
of the Exchange Act.

Item 5.     Interests of Named Experts and Counsel


                                     II-1
<PAGE>   3
            The validity of the shares of Common Stock to be offered hereunder
has been passed upon for the Company by Gray Cary Ware & Freidenrich, A
Professional Corporation. As of January 6, 1997 a partnership comprised of
certain current and former attorneys of Gray Cary Ware & Freidenrich owned 5,072
shares of Class A Common Stock of the Company.

Item 6.     Indemnification of Directors and Officers

            Section 145 of the Delaware General Corporation Law permits
indemnification of officers, directors, and other corporate agents under certain
circumstances and subject to certain limitations. The Registrant's Certificate
of Incorporation and By-Laws provide that the Registrant shall indemnify its
directors, officers, employees and agents to the full extent permitted by
Delaware General Corporation Law, including in circumstances in which
indemnification is otherwise discretionary under Delaware law. In addition, the
Registrant has entered into separate indemnification agreements with its
directors and officers which would require the Registrant, among other things,
to indemnify them against certain liabilities which may arise by reason of their
status or service (other than liabilities arising from willful misconduct of a
culpable nature) and to maintain directors' and officers' liability insurance,
if available on reasonable terms.

            These indemnification provisions and the indemnification agreement
entered into between the Registrant and its officers and directors may be
sufficiently broad to permit indemnification of the Registrant's officers and
directors for liabilities (including reimbursement of expenses incurred) arising
under the Securities Act.

Item 7.     Exemption From Registration Claimed

            Inapplicable.

Item 8.     Exhibits

            See Exhibit Index.

Item 9.     Undertakings

            (a)     Rule 415 Offering

            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 Securities Act of 1933;


                                     II-2
<PAGE>   4
                    (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;

                    (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 paragraphs (a)(1)(i) and (a)(l)(ii) do not apply if the
registration statement is on Form S-3 or Form S-8, and 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 Exchange Act that are incorporated by reference in the registration
statement.

            (2) That, for the purpose of determining any liability under the
Securities Act of 1933, 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)  Filing incorporating subsequent Exchange Act documents by reference

            The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in 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.

       (h)  Request for acceleration of effective date or filing of
            registration statement on Form S-8

            Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such


                                     II-3
<PAGE>   5
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 Act and will be governed by the final adjudication of
such issue.

                                   SIGNATURES

   Pursuant to the requirements of the Securities Act of 1933, the Registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements of filing on Form S-8 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, in the County of Santa
Clara, City of Mountain View, California, on January 10, 1997.

            These indemnification provisions and the indemnification agreement
entered into between the Registrant and its officers and directors may be
sufficiently broad to permit indemnification of the Registrant's officers and
directors for liabilities (including reimbursement of expenses incurred) arising
under the Securities Act.

Item 7.     Exemption From Registration Claimed

            Inapplicable.

Item 8.     Exhibits

            See Exhibit Index.

Item 9.     Undertakings

            (a)     Rule 415 Offering

            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 Securities Act of 1933;

                                     II-2
4
                    (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;

                    (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 paragraphs (a)(1)(i) and (a)(l)(ii) do not apply if the
registration statement is on Form S-3 or Form S-8, and 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 Exchange Act that are incorporated by reference in the registration
statement.

            (2) That, for the purpose of determining any liability under the
Securities Act of 1933, 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)  Filing incorporating subsequent Exchange Act documents by reference

            The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in 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.

       (h)  Request for acceleration of effective date or filing of
            registration statement on Form S-8

            Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such

                                     II-3
5
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 Act and will be governed by the final adjudication of
such issue.

                                     II-4

                                   SIGNATURES

   Pursuant to the requirements of the Securities Act of 1933, the Registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements of filing on Form S-8 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, in the County of Santa
Clara, City of Mountain View, California, on January 10, 1997.
