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 Securities Act and will be governed by the final adjudication of such issue. </P>

We are filing this Registration Statement to register (i) an additional 1,200,000 shares of our common stock, par value $0.01 per share
(the "Common Stock"), that may be acquired by Company employees under the Packaging Corporation of America Retirement Savings Plan for Salaried Employees (the "Savings Plan") and (ii) an additional 300,000 shares of our

We previously filed the Original Registration Statement on March 23, 2000 covering, among other things, 5,800,000

of our Common Stock that may be acquired by Company employees under the Thrift Plan and (ii) an additional 1,400,000 shares of our Common Stock that may be acquired by Company employees under the Savings Plan. On February 22, 2012, we

(b) the description of the Company's common stock, par value $0.01 per share, included
under the caption "Description of Capital Stock" in the Prospectus forming a part of the Company's Registration Statement on Form S-1, initially filed with the Commission on September 13, 1999 (Registration No. 333-86963),
including exhibits, as amended, and as may be further amended from time to time, which description has been incorporated by reference in Item 1 of the Company's Registration Statement on Form 8-A, filed pursuant to Section 12 of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), on October 15, 1999 (Registration No. 001-15399).
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 which indicates that all securities offered hereby have been sold or which deregisters all securities then remaining unsold, shall be deemed to be incorporated by reference herein and to be a part hereof from the date of
filing of such documents.
Any statement contained in a document incorporated or deemed to be incorporated by reference herein shall be
deemed to be modified or superseded for purposes of this Registration Statement to the extent that a statement contained herein or in any other subsequently filed document which also is or is deemed to be incorporated by reference herein modifies or
supersedes such statement. Any statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Registration Statement.
Item 5.
Interests of Named Experts and Counsel.
Certain legal matters in connection with the
issuance of the shares of Common Stock offered hereby will be passed upon for the Company by Kent A. Pflederer, Senior Vice President, General Counsel and Corporate Secretary of the Company. Mr. Pflederer is the beneficial owner of 38,132
shares of the Company's Common Stock.
Item 8.
Exhibits.
See the accompanying Exhibit Index for a list of Exhibits to this
Registration Statement, which is incorporated by reference herein.
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 Securities Act;
(ii) to reflect in the prospectus any facts or events
arising after the effective date of this Registration Statement (or 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. Notwithstanding the foregoing, any increase or decrease in the volume of securities
1
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 a twenty percent change in the maximum aggregate offering price set forth in the
"Calculation of Registration Fee" table in the effective 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 paragraphs (a)(1)(i) and (a)(1)(ii) of this section 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 Company pursuant to section 13 or section 15(d) of the Exchange Act that are incorporated by reference in this
Registration Statement;
(2) that, for the purpose of determining any liability under the Securities 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 offering.
(b) The undersigned registrant
hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Company'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 this Registration Statement shall be deemed to be a new registration statement relating to the securities
offered herein, 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 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 Securities 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 Securities Act and will be governed by the final adjudication of such issue.
