</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)&nbsp;To file, during any period in which offers or sales are being made, a post-effective
amendment to this registration statement:
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)&nbsp;To include any prospectus required by Section&nbsp;10(a)(3) of the Securities Act of 1933;
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)&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 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&nbsp;percent change in the maximum aggregate
offering price set forth in the &#147;Calculation of Registration Fee&#148; table in the effective
registration statement; and
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)&nbsp;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;
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><I>provided, however</I>, that paragraphs (1)(i), (1)(ii) and (1)(iii) above do not apply if the
information required to be included in a post-effective amendment by those paragraphs is contained
in reports filed with or furnished to the Commission by the registrant pursuant to Section&nbsp;13 or
Section 15(d) of the Exchange Act of 1934 that are incorporated by reference in the registration
statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of
the registration statement.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&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 <I>bona fide </I>offering thereof.

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4)&nbsp;That, for purposes of determining any liability under the Securities Act of 1933, each

1934 (and, where applicable, each filing of an employee benefit plan&#146;s annual report pursuant to
Section 15(d) of the 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 <I>bona

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&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
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
against the registrant 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 of 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.

Kaiser Aluminum Corporation (the "Company") previously registered 2,222,222 shares of common
stock issuable pursuant to the Kaiser Aluminum Corporation 2006 Equity and Performance
Incentive Plan on a registration statement on Form S-8 filed by the Company on July 6, 2006.
The Kaiser Aluminum Corporation 2006 Equity and Performance Incentive Plan was most recently amended and
restated effective as of June 8, 2010 (as so amended and restated, the "Plan"), at which time
the number of shares of common stock issuable thereunder was increased by 500,000 shares. The
additional 500,000 shares of common stock issuable pursuant to the Plan are being registered on
this registration statement. Pursuant to Rule 416 of the Securities Act of 1933, as amended
(the "Securities Act of 1933"), this registration statement also relates to such other shares as
may be issuable as a result of certain adjustments, including, without limitation, stock
dividends and stock splits.
(2)
Estimated solely for the purpose of calculating the registration fee pursuant to Rule 457(c)
and (h) under the Securities Act of 1933, based on the average of the high and low prices per
share of the Company's common stock as reported on The NASDAQ Global Select Market on November
3, 2010.
(3)
The registration fee is being offset by $1,870 previously paid by the Company with respect to
4,392,265 shares of common stock sought to be registered with the Securities and Exchange
Commission pursuant to a registration statement on Form S-3 filed by the Company on April 2,
2010. Subsequent to the filing of such registration statement, the number of shares being
registered thereon was reduced to 3,708,922, which resulted in the reduction of the
registration fee in the amount of $1,870.

(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 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

(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 paragraphs (1)(i), (1)(ii) and (1)(iii) above do not apply if the
information required to be included in a post-effective amendment by those paragraphs is contained
in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or
Section 15(d) of the Exchange Act of 1934 that are incorporated by reference in the registration
statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of
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.
(4) 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 15(d) of the Exchange Act of
1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the 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.
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
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
against the registrant 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 of 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.
