PACKAGING CORPORATION OF AMERICA

6.50% SENIOR NOTES DUE 2018

Packaging Corporation of America, a corporation duly organized and existing under the General Corporation Law of the State of Delaware (hereinafter called the “Company,” which term includes any successor under the Indenture referred to below), for value received, hereby promises to pay to Cede & Co., or registered assigns, the principal sum of ONE HUNDRED AND FIFTY MILLION DOLLARS ($150,000,000) on March 15, 2018, and to pay interest thereon from and including March 25, 2008, or from and including the most recent date to which interest has been paid or duly provided for, to, but not including, the applicable Interest Payment Date (as defined below) or Maturity, as the case may be. The Company will pay interest semiannually in arrears on March 15 and September 15 of each year (each, an “Interest Payment Date”), commencing September 15, 2008 and at Maturity, at the rate of 6.50% per annum, until the principal hereof is paid or duly made available for payment. Interest on this Note shall be calculated on the basis of a 360-day year consisting of twelve 30-day months. The interest so payable and punctually paid or duly provided for on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on the on the date (whether or not a Business Day) that is fifteen calendar days prior to such Interest Payment Date. Any such interest which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date shall forthwith cease to be payable to the Person who was the Holder hereof on the relevant Regular Record Date by virtue of having been such Holder, and may be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to the Holder of this Note not less than 10 days prior to such Special Record Date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in such Indenture.

Payment of the principal of and premium, if any, and the interest on this Note will be made at the office or agency of the Company maintained for that purpose in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and

private debts; provided, however, that, at the option of the Company, interest may be paid by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register or by transfer to an account maintained by the payee with a bank located in the United States.

This Note is one of a duly authorized issue of Securities of the Company (herein called the “Notes”) issued and to be issued in one or more series under an Indenture dated as of July 21, 2003 (the “Indenture”), between the Company and U.S. Bank National Association, as trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Notes, and the terms upon which the Notes are, and are to be, authenticated and delivered. This Note is one of the series designated on the face hereof, initially limited (subject to exceptions provided in the Indenture) in aggregate principal amount to $150,000,000, subject to the right of the Company, without the consent of the Holders of the Notes, to “reopen” such series and to issue additional Notes of such series on the terms and subject to the conditions provided in or pursuant to the Indenture.

The interest rate payable on the Notes shall be subject to adjustments (each an “Interest Rate Adjustment”) from time to time if either Moody’s or S&P, or any Substitute Rating Agency, downgrades (or subsequently upgrades) the debt rating assigned to the Notes, in the manner described below.

If the rating of the Notes from Moody’s or any Substitute Rating Agency is decreased to a rating set forth in the immediately following table, the interest rate on the Notes shall increase from the interest rate payable on the Notes on the date of their issuance by the percentage set forth opposite that rating:

Rating*		Percentage

Ba1		0.25%

Ba2		0.50%

Ba3		0.75%

B1 or below		1.00%

* Including the equivalent ratings of any Substitute Rating Agency.

If the rating of the Notes from S&P or any Substitute Rating Agency is decreased to a rating set forth in the immediately following table, the interest rate on the Notes shall increase from the interest rate payable on the Notes on the date of their issuance by the percentage set forth opposite that rating:

Rating*		Percentage

BB+		0.25%

BB		0.50%

BB-		0.75%

B+ or below		1.00%

* Including the equivalent ratings of any Substitute Rating Agency.

If at any time the interest rate on the Notes has been adjusted upward and either Moody’s or S&P (or either Substitute Rating Agency), as the case may be, subsequently increases its rating of the Notes to any of the threshold ratings set forth above, the interest rate on the Notes shall be decreased such that the interest rate for the Notes equals the interest rate payable on the Notes on the date of their issuance plus the applicable percentages set forth opposite the ratings from the tables above in effect immediately following the increase. If Moody’s or any Substitute Rating Agency subsequently increases its rating of the Notes to Baa3 (or its equivalent, in the case of a Substitute Rating Agency) or higher and S&P or any Substitute Rating Agency increases its rating of the Notes to BBB- (or its equivalent, in the case of a Substitute Rating Agency) or higher, the interest rate on the Notes shall be decreased to

A-2

the interest rate payable on the Notes on the date of their issuance. In addition, the interest rate on the Notes shall permanently cease to be subject to any Interest Rate Adjustment described above (notwithstanding any subsequent decrease in the ratings by either or both rating agencies) if the Notes become rated Baa1 and A- or higher by Moody’s (or its equivalent, in the case of a Substitute Rating Agency) and S&P (or its equivalent, in the case of a Substitute Rating Agency), respectively (or one of these ratings, if the Notes are only rated by one rating agency).

Each adjustment required by any decrease or increase in a rating set forth above, whether occasioned by the action of Moody’s, S&P or any Substitute Rating Agency, shall be made independent of any and all other adjustments. In no event shall (1) the interest rate payable on the Notes be reduced to below the interest rate payable on the Notes on the date of their issuance or (2) the total increase in the interest rate payable on the Notes exceed 2.00% above the interest rate payable on the Notes on the date of their issuance.

No adjustments in the interest rate payable on the Notes shall be made solely as a result of a rating agency ceasing to provide a rating. If at any time less than two rating agencies provide a rating of the Notes, the Company will use its commercially reasonable efforts to obtain a rating of the Notes from another rating agency, to the extent one exists, and if another such rating agency rates the Notes (such rating agency, a “Substitute Rating Agency”), for purposes of determining any increase or decrease in the interest rate on the Notes pursuant to the table above (a) such Substitute Rating Agency will be substituted for the last rating agency to provide a rating of the Notes but which has since ceased to provide such rating, (b) the relative ratings scale used by such Substitute Rating Agency to assign ratings to senior unsecured debt will be determined in good faith by an independent investment banking institution of national standing appointed by the Company and, for purposes of determining the applicable ratings included in the applicable table above with respect to such Substitute Rating Agency, such ratings will be deemed to be the equivalent ratings used by Moody’s or S&P, as applicable, in such table and (c) the interest rate payable on the Notes will increase or decrease, as the case may be, such that the interest rate equals the interest rate payable on the Notes on their date of issuance plus the appropriate percentage, if any, set forth opposite the rating from such Substitute Rating Agency in the applicable table above (taking into account the provisions of clause (b) above) (plus any applicable percentage resulting from a decreased rating by the other rating agency). For so long as only one rating agency provides a rating of the Notes, any subsequent increase or decrease in the interest rate of the Notes necessitated by a reduction or increase in the rating by the agency providing the rating shall be twice the percentage set forth in the applicable table above. For so long as no rating agency provides a rating of the Notes, the interest rate on the Notes shall increase to, or remain at, as the case may be, 2.00% above the interest rate payable on the Notes on the date of their issuance.

Any Interest Rate Adjustment described above shall take effect from the first day of the interest period during which a rating change requires an adjustment in the interest rate. If Moody’s or S&P or any Substitute Rating Agency changes its rating of the Notes more than once during any particular interest period, the last change by such agency during such period shall control for purposes of any Interest Rate Adjustment described above relating to such agency’s action.

If the interest rate payable on the Notes is increased pursuant to an Interest Rate Adjustment, the term “interest,” as used in this Note, shall be deemed to include any such additional interest unless the context otherwise requires.

The Notes may be redeemed by the Company, in whole or from time to time in part, at the option of the Company on any date at a Redemption Price equal to the greater of (i) 100% of the principal amount of the Notes to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed (exclusive of interest accrued to the applicable Redemption Date) discounted to such Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 50 basis points, plus, in the case of both clause (i) and clause (ii) above, accrued and unpaid interest on the principal amount of the Notes being redeemed up to, but not including, such Redemption Date; provided, however, that installments of interest whose Stated Maturity is on or prior to the Redemption Date will be payable to the Holders of the Notes (or one or more Predecessor Notes) registered as such at the close of business on the relevant Regular Record Dates according to their terms and the provisions of the Indenture. Any such redemption shall be effected in accordance with the terms and conditions set forth in the Indenture.

A-3

Notice of any redemption will be mailed at least 30 days but not more than 60 days before the applicable Redemption Date to each Holder of the Notes to be redeemed at such Holder’s registered address. If less than all the Notes are to be redeemed at the Company’s option, the Trustee will select, in such manner as it deems fair and appropriate, the Notes (or portions thereof) to be redeemed. Unless the Company defaults in payment of the Redemption Price, on and after the applicable Redemption Date interest will cease to accrue on the Notes or portions thereof called for redemption on such Redemption Date.

If a Change of Control Triggering Event occurs, unless the Company has previously exercised its right to redeem the Notes as described above, the Company will make an offer to each Holder of Notes to repurchase all or any part (equal to $2,000 or integral multiples of $1,000 in excess thereof) of that Holder’s Notes at a Repurchase Price in cash equal to 101% of the aggregate principal amount of Notes repurchased plus any accrued and unpaid interest on the Notes repurchased to the applicable Repurchase Date. Within 30 days following any Change of Control Triggering Event or, at the option of the Company, prior to any Change of Control, but after the public announcement of an impending Change of Control, the Company will mail a notice to each Holder, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Triggering Event and offering to repurchase the Notes on the Change of Control Triggering Event Repayment Date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed. The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control being consummated on or prior to the Repurchase Date specified in such notice.

The Company will comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934 (the “Exchange Act”) and any other securities laws and regulations thereunder, to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Triggering Event provisions of the Notes, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control Triggering Event provisions of the Notes by virtue of such conflict.

On the Change of Control Triggering Event Repayment Date, the Company will, to the extent lawful: (a) accept for payment all Notes or portions of Notes properly tendered pursuant to the Company’s offer; (b) deposit with the Paying Agent an amount equal to the aggregate Repurchase Price in respect of all Notes or portions of Notes properly tendered; and (c) deliver or cause to be delivered to the Trustee the Notes properly accepted, together with an Officers’ Certificate stating the aggregate principal amount of Notes being purchased by the Company.

The Paying Agent will promptly mail to each Holder of Notes properly tendered the Repurchase Price for the Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unpurchased portion of any Notes surrendered; provided, that each new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

The Company will not be required to make an offer to repurchase the Notes upon a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and such third party purchases all Notes properly tendered and not withdrawn under its offer. An offer to repurchase the Notes upon a Change of Control Triggering Event may be made in advance of a Change of Control Triggering Event, if a definitive agreement is in place for a Change of Control at the time of the making of a such an offer.

As used in this Note, the following terms have the meaning set forth below:

“Below Investment Grade Rating Event” occurs if the Notes cease to be rated Investment Grade by each of the Rating Agencies on any date during the period (the “Trigger Period”) commencing 60 days prior to the first public announcement by the Company of any Change of Control (or pending Change of Control) and ending 60 days following consummation of such Change of Control (which Trigger Period shall be extended following consummation of a Change of Control for so long as any of the Rating Agencies has publicly announced that it is considering a possible ratings change). If a Rating Agency is not providing a rating for the Notes at the

A-4

commencement of any Trigger Period, the Notes will be deemed to have ceased to be rated Investment Grade by such Rating Agency during that Trigger Period. Notwithstanding the foregoing, no Below Investment Grade Rating Event will be deemed to have occurred in connection with any particular Change of Control unless and until such Change of Control has actually been consummated.

“Change of Control” means the occurrence of any of the following:

(1) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the assets of the Company and its Subsidiaries taken as a whole to any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) other than the Company or one of its Subsidiaries;

(5) the Company consolidates with, or merges with or into, any “person” (as that term is used in Section 13(d)(3) of the Exchange Act), or any person consolidates with, or merges with or into, the Company, in any such event pursuant to a transaction in which any of the outstanding Voting Stock of the Company or any of the outstanding Voting Stock of such other person is converted into or exchanged for cash, securities or other property, other than any such transaction where the shares of the Voting Stock of the Company outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of the surviving person immediately after giving effect to such transaction.

“Change of Control Triggering Event” means the occurrence of both a Change of Control and a Below Investment Grade Rating Event.

“Continuing Directors” means, as of any date of determination, any member of the Company’s board of directors who (1) was a member of such board of directors on the date of the issuance of the Notes; or (2) was nominated for election or elected to such board of directors with the approval of a majority of the Continuing Directors who were members of such board of directors at the time of such nomination or election (either by a specific vote or by approval of the Company’s proxy statement in which such member was named as a nominee for election as a director).

A-5

“Final Maturity Date” means March 15, 2018.

“Independent Investment Banker” means, with respect to any Redemption Date for the Notes, Deutsche Bank Securities Inc. and its successors or X.X. Xxxxxx Securities Inc. and its successors, whichever is selected by the Trustee after consultation with the Company, or, if both such firms or the respective successors, if any, to such firms, as the case may be, are unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing in the United States of America appointed by the Trustee after consultation with the Company.

“Investment Grade” means a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating categories of Moody’s) and a rating of BBB- or better by S&P (or its equivalent under any successor rating categories of S&P) or the equivalent investment grade credit rating from any additional Rating Agency or Rating Agencies.

“Reference Treasury Dealers” means, with respect to any Redemption Date for the Notes, Deutsche Bank Securities Inc. and X.X. Xxxxxx Securities Inc. and their respective successors (provided, however, that if either such firm or any such successor, as the case may be, ceases to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Trustee, after consultation with the Company, shall substitute therefor another Primary Treasury Dealer) and three other Primary Treasury Dealers selected by the Trustee after consultation with the Company.

A-6

Redemption Date. The Treasury Rate shall be calculated on the third Business Day preceding the applicable Redemption Date. As used in the immediately preceding sentence and in the definition of “Reference Treasury Dealer Quotations” below, the term “Business Day” means each Monday, Tuesday, Wednesday, Thursday and Friday which is not a day on which banking institutions in The City of New York are authorized or obligated by law, regulation or executive order to close.

If an Event of Default with respect to the Notes shall occur and be continuing, the principal of and accrued and unpaid interest on the Notes may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of Securities of each series issued under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in aggregate principal amount of the Securities at the time Outstanding of each series affected thereby. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities of any series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Notes issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note. The Indenture also permits the Company and the Trustee, without notice to or consent of the Holders of the Notes, to enter into one or more indentures supplemental thereto for the purposes specified in the Indenture.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and premium, if any, and interest on this Note at the time, place and rate, and in the coin or currency, herein and in the Indenture prescribed.

As provided in the Indenture and subject to certain limitations set forth therein, the transfer of this Note may be registered on the Security Register upon surrender of this Note for registration of transfer at the Office or Agency of the Company maintained for the purpose in any place where the principal of and interest on this Note are payable, duly endorsed, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder hereof or by his attorney duly authorized in writing, and thereupon one or more new Notes, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Notes are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations set forth therein, the Notes are exchangeable for a like aggregate principal amount of Notes of authorized denominations as requested by the Holders surrendering the same.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith, other than in certain cases provided in the Indenture.

Prior to due presentment of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note shall be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

A-7

The Indenture contains provisions whereby (i) the Company may be discharged from its obligations with respect to the Notes (subject to certain exceptions) or (ii) the Company may be released from its obligations under specified covenants and agreements in the Indenture, in each case if the Company irrevocably deposits with the Trustee money or Government Obligations sufficient to pay and discharge the entire indebtedness on all Notes, and satisfies certain other conditions, all as more fully provided in the Indenture. In addition, the Indenture shall cease to be of further effect (subject to certain exceptions) with respect to the Notes when (1) either (A) all Notes previously authenticated and delivered have been delivered (subject to certain exceptions) to the Trustee for cancellation, or (B) all Notes (i) have become due and payable, (ii) will become due and payable at their Stated Maturity within one year or (iii) are to be called for redemption within one year and, in the case of (i), (ii) or (iii) of this sentence, the Company has irrevocably deposited with the Trustee money in an amount sufficient to pay and discharge the entire indebtedness on all such Notes not theretofore delivered to the Trustee for cancellation, and (2) the Company satisfies certain other conditions, all as more fully provided in the Indenture.

This Note shall be governed by and construed in accordance with the laws of the State of New York.

All terms used in this Note which are defined in the Indenture and not defined herein shall have the meanings assigned to them in the Indenture.

Unless the certificate of authentication hereon has been executed by or on behalf of the Trustee under the Indenture by the manual signature of one of its authorized signatories, this Note shall not be entitled to any benefits under the Indenture or be valid or obligatory for any purpose.
