paragraphs is contained in periodic reports filed by the Registrant pursuant to
Section&nbsp;13 or Section 15(d) of the Securities Exchange Act 1934 that are
incorporated by reference in the Registration Statement.



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)&nbsp;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.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)&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 offering.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant&#146;s annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan&#146;s annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) 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.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;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 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.

KLA-Tencor Corporation (the
"Registrant"
or the
"Company"
) hereby
incorporates by reference in this Registration Statement the following
documents:
(a)
Registrant's Annual Report on Form 10-K for the fiscal year
ended June 30, 2004 (File No. 000-09992) filed pursuant to Section
13(a) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"
);
(b)
All other reports filed by the Registrant pursuant to Section
13(a) or 15(d) of the Exchange Act since the end of the fiscal year
covered by the Annual Report referred to in (a) above;
(c)
The description of the Registrant's Common Stock as set forth
in the Registration Statement filed by the Registrant on Form 8-A on
March 29, 1989 (File No. 000-09992) pursuant to Section 12(g) of the
Exchange Act and any amendments or reports thereto filed with the
Securities and Exchange Commission for the purpose of updating such
description including Amendment No. 1 to Form 8-A filed September 25,
1995 and Amendment No. 2 to Form 8-A filed September 24, 1996; and
(d)
All other descriptions of the Registrant's Common Stock
contained in a registration statement filed under the Exchange Act,
including any amendment or report filed for the purpose of updating
such description.
All documents subsequently filed by the Registrant 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.
Not applicable.
Item 5. Interests of Named Experts and Counsel.
Not applicable.
Item 6. Indemnification of Directors and Officers.
Section 145(a) of the Delaware General Corporation Law (the
"DGCL"
)
provides in relevant part that "[a] corporation shall have power to indemnify
any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the corporation) by reason of the fact that the person is or was a
director, officer, employee or agent of the corporation, or is or was serving
at the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint
II-1
Table of Contents
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by the person in connection with such action, suit or proceeding if
the person acted in good faith and in a manner the person reasonably believed
to be in or not opposed to the best interests of the corporation, and, with
respect to any criminal action or proceeding, had no reasonable cause to
believe the person's conduct was unlawful." With respect to derivative
actions, Section 145(b) of the DGCL provides in relevant part that "[a]
corporation shall have power to indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending or completed action
or suit by or in the right of the corporation to procure a judgment in its
favor by reason of the fact that the person is or was a director, officer,
employee or agent of the corporation, or is or was serving at the request of
the corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, against
expenses (including attorneys' fees) actually and reasonably incurred by the
person in connection with the defense or settlement of such action or suit if
the person acted in good faith and in a manner reasonably believed to be in or
not opposed to the best interests of the corporation and except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the Court of Chancery or the court in which
such action or suit was brought shall determine upon application that, despite
the adjudication of liability but in view of all the circumstances of the case,
such person is fairly and reasonably entitled to indemnity for such expenses
which the Court of Chancery or such other court shall deem proper."
The Registrant's Amended and Restated Certificate of Incorporation
provides that to the fullest extent permitted by the DGCL, no director of the
Registrant shall be personally liable to the Registrant or its stockholders for
monetary damages for breach of fiduciary duty as a director. The Amended and
Restated Certificate of Incorporation also provides that no amendment or repeal
of such provision shall apply to or have any effect on the right to
indemnification permitted thereunder with respect to claims arising from acts
or omissions occurring in whole or in part before the effective date of such
amendment or repeal whether asserted before or after such amendment or repeal.
The Registrant's Bylaws provide that the Registrant shall indemnify to the
fullest extent permitted by the DGCL each of its directors, officers, employees
and other agents against expenses actually and reasonably incurred in
connection with any proceeding arising by reason of the fact that such person
is or was an agent of the Registrant.
The Registrant has entered into indemnification agreements with its
directors and executive officers and intends to enter into indemnification
agreements with any new directors and executive officers in the future.
Item 7. Exemption from Registration Claimed
Not applicable.
Item 8. Exhibits
See Exhibit Index.
Item 9. Undertakings
(a) The undersigned registrant hereby undertakes:
II-2
Table of Contents
(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)
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 paragraphs (a)(1)(i) and (a)(1)(ii) do 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 Securities Exchange Act 1934 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) 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
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) 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.
(c) 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 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.
