include any prospectus required by Section&nbsp;10(a)(3) of the 1933 Act, </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)&nbsp;&nbsp;to
reflect in the prospectus any facts or events arising after the effective date of this 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 this Registration Statement; and </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)&nbsp;&nbsp;to

information in this Registration Statement; provided, however, that clauses (1)(i)&nbsp;and (1)(ii)&nbsp;shall not apply if the information required to be included in a post-effective
amendment by those clauses is contained in periodic reports filed by the Registrant pursuant to Section&nbsp;13 or Section&nbsp;15(d) of the 1934 Act that are incorporated by reference into this
Registration Statement; </FONT></P>

</UL>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)&nbsp;&nbsp;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

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)&nbsp;&nbsp;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

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B.&nbsp;&nbsp;&nbsp;&nbsp;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&nbsp;13(a) or Section&nbsp;15(d) of the 1934 Act that is incorporated by reference into this 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. </FONT></P>


<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C.&nbsp;&nbsp;&nbsp;&nbsp;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
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. </FONT></P>

99.1
Oak Technology, Inc. Amended and Restated 1994 Employee Stock Purchase Plan
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 this 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 this Registration Statement; and
(iii)  to
include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such
information in this 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 clauses 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 this
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
Registrant's Amended and Restated 1994 Employee Stock Purchase Plan.
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 that is incorporated by reference into this 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
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.
3
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 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
Sunnyvale, State of California, on August 26, 2002.
