Investments LP, any such director appointed by MDCP IV Global Investments LP pursuant to this
paragraph 1H shall be deemed an additional MDCP IV Global Director for purposes of this Agreement.

1I.Purchased Equity Director.Each Purchased Equity Holder who, together with his Affiliates and/or Family
Group, owns (i) prior to a Listing, Ordinary Shares, as of any date of determination, with an aggregate investment cost (i.e., subscription price or purchase price paid for Ordinary Shares plus
any other amounts contributed to or invested in the Company not specifically for the acquisition of Ordinary Shares or loans made to the Company, and which, for the avoidance of doubt shall be deemed
to include the aggregate investment cost of Ordinary Shares) of not less than €50,000,000 or (ii) on and after a Listing, (x) a number of Ordinary Shares, which when
multiplied by the per share listing price on the securities market on which the Ordinary Shares are listed, has an aggregate value equal to not less than €50,000,000 or

Shares plus any other amounts contributed to or invested in the Company not specifically for the acquisition of Ordinary Shares or loans made to the Company) of the Ordinary Shares held by such
Purchased Equity Holder and his or its Affiliates and Family Group as of the Settlement Date, then such Purchased Equity Holder or (if such holder is an individual), upon such holder's death, a
descendant of such Purchased Equity Holder (any such Person, an "Eligible Purchased Equity Holder") shall have the right to appoint one member of the
Board (a "Purchased Equity Director"). The condition specified in clauses (i) and (ii) of this paragraph 1I are referred to herein
as the "Minimum Investment Condition." Until such date as the applicable Minimum Investment Condition has no longer been satisfied or unless a Purchased
Equity Director becomes ineligible to serve as a director as a matter of law, the removal from the Board, a Subsidiary Board or any committee (with or without cause) of any Purchased Equity Director
shall be at the written request of the appointing Eligible Purchased Equity Holder, but only upon such written request and under no other circumstances;providedthat in the event that a Purchased
Equity Director (without the consent of the

---



Board)
becomes an employee of, serves as a director of, or otherwise provides services for, any Person (other than Smurfit-Stone Container Corp. and its Subsidiaries) that competes with a material
business of the Group Companies, such Purchased Equity Director shall be removed upon the written request of MDCP IV Global Investments LP. Until the rights of any Eligible Purchased Equity Holder to
elect a director pursuant to this paragraph 1I are terminated or unless a Purchased Equity Director becomes ineligible to serve as a director as a matter of law, in the event that any Purchased
Equity Director ceases to serve as a member of the Board, a Subsidiary Board or any committee during his term of office, the resulting vacancy on the Board, the Subsidiary Board or such committee
shall be filled by a representative designated by the Eligible Purchased Equity Holder originally appointing such Purchased Equity Director as provided hereunder. As of and after the date that any
Eligible Purchased Equity Holder ceases to satisfy the applicable Minimum Investment Condition or the Purchased Equity Director has become ineligible to serve as a director as a matter of law, at the
election of MDCP IV Global Investments LP, the Purchased Equity Director shall resign or be removed from the Board, and the Investors shall take all actions to remove such Purchased Equity Director.
In the event that the Purchased Equity Director resigns or is removed as a result of an Eligible Purchased Equity Holder's failure to satisfy the Minimum Investment Condition, MDCP IV Global
Investments LP shall be entitled to appoint any individuals to serve as directors as a result of the resignation or removal of the Purchased Equity Director. Unless otherwise agreed to in writing by
MDCP IV Global Investments LP, any such director appointed by MDCP IV Global Investments LP pursuant to this paragraph 1I shall be deemed an additional MDCP IV Global Director for purposes of
this Agreement. Notwithstanding anything else to the contrary in this paragraph 1I, (A) in no event shall any Purchased Equity Holder have any rights pursuant to clause (ii) of
this paragraph 1I unless such Purchased Equity Holder at some point prior to a Listing satisfied the condition specified in clause (i) hereof, (B) Purchased Equity
Holders, in the aggregate and subject to the conditions set forth in this paragraph 1I, shall not be able to appoint more than one Purchased Equity Director to serve on the Board at any one
time, and (C) in no event shall any Purchased Equity Holder have any right to appoint a Purchased Equity Director at a time when such Person is a member of the Board, has nominated a member of
the Board, and has the right by contract (other than this paragraph 1I), operation of law or sufficient voting power through ownership of Ordinary Shares to elect, appoint or nominate a member
of the Board.

1J.Process.Any appointment or removal of a director shall be effected by delivery to the Company's registered
office of written notice signed by the Investor or Investors making such appointment or removal and shall take effect upon such delivery or, if later, any effective date stated in the notice.

Section 2.Certain Governance Rights.

2A.Affiliate Transactions.The Company shall not, without the prior consent of its Board (including, as long as
any such Person serves on the Board, at least one Management Investor or if no Management Investor serves on the Board, the Purchased Equity Director as long as such individual serves on the Board),
from and after the Effective Date, enter into, or permit any Subsidiary to enter into, any transaction with any Person or group of related Persons that are not Independent Third Parties (each, an
"Affiliated Person") or with any Person in which any such Affiliated Person owns more than a 25% beneficial interest; providedthat the consent of any
Management Investor or the Purchased Equity Director shall not be required with respect to contracts in the ordinary
course of business of the Company or its Subsidiaries or contracts that are negotiated on an arm's-length basis and are on terms which are commercially reasonable.

2B.Accounting Policies.The Company shall not for purposes of calculating or determining whether any management
incentive target had been achieved or satisfied, change any accounting policy of the Company in a manner that would adversely affect the calculation of any management incentive target or performance; providedthat the Company may change such accounting policy if, under the supervision of the Board, management incentive targets or bonuses are

---



performance
and/or other injunctive relief in order to enforce or prevent any violations of the provisions of this Agreement.

directors pursuant to paragraph 1B, paragraph 1G or paragraph 1H to any other Person to whom it is transferring or has transferred equity securities of the Company. In the event
that the MDCP Co-Investor Majority determines that any amendment to this Agreement is necessary or desirable to effectuate the assignment and the granting of rights to a Person in
accordance with the immediately foregoing sentence, each Investor party hereto shall execute and deliver to the Company a counterpart of any amendment that is consistent with the rights that may be
assigned by MDCP IV Global Investments LP or MDCP III Global Investments LP pursuant to the immediately foregoing sentence;providedthat in the event

co-investor, each of the MDCP Co-Investors shall, as a condition to such transfer, require such

---



co-investor
to execute an agreement for the benefit of the Management Investors pursuant to which such co-investor will vote its Ordinary Shares in favor of the appointment of
the Management Investors (and to the extent rights have arisen pursuant to paragraph 1I, the Purchased Equity Director) to the Board to the extent required by Section 1 of this
Agreement. Notwithstanding anything else to the contrary set forth herein, in no event shall MDCP IV Global Investments LP be entitled to assign all or any portion of its rights pursuant to
paragraph 1I without the consent of the Company and each of the Management Investors.

4D.Severability.Whenever possible, each provision of this Agreement shall be interpreted in such manner as to
be effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent
of such prohibition or invalidity, without invalidating the remainder of this Agreement.

4E.Counterparts.This Agreement may be executed simultaneously in two or more counterparts, any one of which
need not contain the signatures of more than one party, but all such counterparts taken together shall constitute one and the same Agreement.

4F.Descriptive Headings; Interpretation.The descriptive headings of this Agreement are inserted for
convenience only and do not constitute a Section of this Agreement. The use of the word "including" in this Agreement shall be by way of example rather than by limitation.

4G.Governing Law; Forum.The Agreement and the exhibits and schedules hereto shall be governed by and construed
in accordance with the laws of Ireland. Any suit or action brought against any Management Investor hereunder should be brought exclusively in the courts of Ireland (it being understood that, except as
set forth in this sentence, nothing contained in this paragraph 4G shall limit any party's rights to bring any suit against any party (other than the Management Investors) or with respect to
the subject matter hereof in any other jurisdiction).

4H.Notices.All notices, demands or other communications to be given or delivered under or by reason of the
provisions of this Agreement shall be in writing and shall be deemed to have been given when delivered personally to the recipient, one day after being sent to the recipient by reputable express

or
to such other address or to the attention of such other person as the recipient party has specified by prior written notice to the sending party.

4I.Effectiveness.This Agreement shall become effective and binding upon each party upon execution and delivery
of this Agreement by each of the Company and such party.

4J.Rights of Management Group.The Management Investors have entered into this Agreement on their own behalf
and, for the purposes of Section 2 of this Agreement, on behalf of the participants in the Company's 2004 Management Equity Plan (the "Management
Group") but the Management Investors shall be entitled in their absolute discretion to exercise (or omit to do so) all powers, authorities and rights granted in
Section 2 of this Agreement without recourse to or consultation with the Management Group. No member of the Management Group shall have any claim or right against the Management Investors on
account of the manner in which he has exercised or failed to exercise any of the said powers, rights and authorities and each member of the Management Group waives any and all rights which he may
hereafter have or acquire as a result of the exercise or manner of exercise or failure to exercise any of the said powers, rights and authorities whether or not in so doing the Management Investors
have acted recklessly or negligently. In no event shall any member of the Management Group (other than the Management Investors) have any right themselves to bring an action or suit against the
Company, any MDCP Co-Investor or any other Person for breach of this Agreement.

4K.Termination.Other than paragraph 1I (which shall terminate upon the earlier of the date that the
Minimum Investment Condition is no longer satisfied and a Sale of the Company), the provisions of this Agreement shall terminate automatically upon the earlier of (i) a Listing and
(ii) a Sale of the Company.
