                                SUPPORT AGREEMENT

          This Support Agreement is made as of March 30, 2004, between Stone
Container Corporation (the "Parent") and Computershare Trust Company of Canada,
in its capacity as trustee of King Street Funding Trust, a trust established
under the laws of the Province of Ontario, by its Administrator, Scotia Capital
Inc. ("King Street").

RECITALS:

1.   The Seller plans to incur certain obligations in its capacity as initial
     servicer (in such capacity, the "Servicer") under a Receivables Purchase
     Agreement dated as of March 30, 2004 (as it may be amended, restated,
     supplemented or otherwise modified, the "Receivables Purchase Agreement").

2.   The Servicer is an indirect subsidiary of the Parent, and the Parent and
     the Servicer desire to provide certain assurances to King Street with
     respect to the ability of the Servicer to faithfully perform its
     obligations as Servicer under the Receivables Purchase Agreement.

3.   MBI Limited/Limitee, in its capacity as General Partner of Smurfit-MBI,
     also plans to incur certain obligations in its capacity as seller (in such
     capacity, the "Seller") under the Receivables Purchase Agreement.

4.   The Parent is in no way providing any support or assurance with respect to
     the Seller's performance of its obligations as Seller under the Receivables
     Purchase Agreement.

5.   It is a condition precedent to the effectiveness of the Receivables
     Purchase Agreement that the Parent provide this Support Agreement for the
     benefit of King Street.

     NOW THEREFORE, in consideration of the mutual promises herein contained and
other good and valuable consideration, the parties hereto agree as follows:

1.   DEFINITIONS. Capitalized terms used and not defined herein shall have the
     respective meanings specified in the Receivables Purchase Agreement and the
     following terms shall have the following meanings:

     "Laws" means applicable laws (including common law), statutes, by-laws,
     rules, regulations, orders, ordinances, codes, treaties, directions,
     decrees, judgments, awards or requirements, in each case of any
     Governmental Authority;

     "Material Adverse Effect" means a material adverse effect on (a) the
     business, operations, property or condition (financial or otherwise) of the
     Parent and its subsidiaries taken as a whole, (b) the ability of the Parent

     the Servicer to perform its obligations under the Receivables Purchase
     Agreement or any of the other Transaction Documents, or (c) the rights or

<Page>

                                      - 2 -

     remedies of King Street against the Parent hereunder or against the
     Servicer under the Receivables Purchase Agreement or any other Transaction
     Document;

     "Support Agreement" means this support agreement, as the same may be
     amended, supplemented, modified, restated or replaced from time to time;
     and

     "Support Termination Date" means the date that is the later of (i) the
     performance in full of the Servicer Obligations and the payment of any
     amounts payable under this Support Agreement, (ii) the Facility Termination
     Date, and (iii) the date on which King Street appoints a successor servicer
     pursuant to Section 4.1(a) of the Receivables Purchase Agreement.

2.   PERFORMANCE OF OBLIGATIONS. The Parent hereby unconditionally and
     irrevocably undertakes and agrees with and for the benefit of King Street
     to cause the due and punctual performance and observance by the Servicer of
     the duties, responsibilities, covenants and obligations of the Servicer
     contained in the Receivables Purchase Agreement or any document delivered
     in connection therewith in accordance with the terms thereof (all such
     duties, responsibilities, covenants and obligations on the part of the
     Servicer, to be performed and observed, being collectively called the
     "Servicer Obligations"), and agrees to pay any and all expenses (including
     reasonable legal fees and expenses) incurred by King Street in enforcing
     any of its rights hereunder. In the event that the Servicer shall fail in
     any manner whatsoever to perform or observe any of the Servicer Obligations
     when the same shall be required to be performed or observed, the Parent
     will itself duly and punctually perform and observe, or will cause the due
     and punctual performance and observance of, the Servicer Obligations, and
     it shall not be a condition to the accrual of the obligation of the Parent
     hereunder to perform or observe any of the Servicer Obligations (or to
     cause the same to be performed or observed) that King Street shall have
     first made any request of or demand upon or give any notice to the Parent
     or to the Servicer or have initiated any action or proceeding against the
     Parent or the Servicer in respect thereof. King Street may proceed to
     enforce the obligations of the Parent under this Section 2 without first
     pursuing or exhausting any right or remedy which King Street may have
     against the Servicer, any other Person, the Purchased Interest or any other
     property. For greater certainty, nothing herein shall create or impose upon
     the Parent any obligation whatsoever with respect to the performance or
     observance of any of the terms, conditions, covenants, agreements,
     undertakings, indemnities or obligations of the Seller contained in the
     Receivables Purchase Agreement or any document delivered in connection
     therewith.

3.   OBLIGATION ABSOLUTE. The Parent undertakes that the Servicer Obligations
     will be performed strictly in accordance with the terms of the Receivables
     Purchase Agreement or any other document delivered in connection therewith,
     regardless of any Law now or hereafter in effect in any jurisdiction
     affecting any of such terms or the rights of King Street with respect
     thereto. The obligations of the Parent under this Support Agreement are
     independent of the Servicer Obligations, and a separate action or actions
     may be brought and prosecuted against the Parent to enforce this Support
     Agreement, irrespective of whether any action is brought against the
     Servicer or whether the Servicer is joined in

<Page>

                                      - 3 -

     any such action or actions. The liability of the Parent under this Support
     Agreement shall be absolute and unconditional irrespective of:

     (a)  any change in the time, manner or place of payment of, or in any other
          term of, all or any of the Servicer Obligations, or any other
          amendment or waiver of or any consent to departure from the
          Receivables Purchase Agreement or any other agreement or instrument
          relating thereto;

     (b)  any change, restructuring or termination of the corporate structure or
          existence of the Parent, the Servicer or any of their Affiliates; or

     (c)  any other circumstance that might otherwise constitute a defense
          available to, or a discharge of, the Parent or the Servicer,

     all whether or not the Parent shall have had notice or knowledge of any act
     or omission referred to in the foregoing clauses (a) through (c),
     inclusive, of this Section 3.

4.   WAIVER. The Parent hereby waives promptness, diligence, notice of
     acceptance or any other notice with respect to any of the Servicer
     Obligations and this Support Agreement and any requirement that King Street
     exhaust any right or take any action against the Servicer or any other
     person or entity.

5.   SUBROGATION. Until the Support Termination Date, the Parent hereby
     postpones all rights of subrogation against the Servicer and its property
     and all rights of indemnification, contribution and reimbursement from the
     Servicer and its property, in each case in connection with this Support
     Agreement and any payments made hereunder, and regardless of whether such
     rights arise by operation of law, pursuant to contract or otherwise.

6.   REPRESENTATIONS AND WARRANTIES OF THE PARENT. By executing and delivering
     this Support Agreement, the Parent hereby represents and warrants to King
     Street, and acknowledges that King Street is relying on such
     representations and warranties in entering into the Receivables Purchase
     Agreement, as follows:

          standing under the laws of its jurisdiction of incorporation, has full
          corporate power and authority to own its properties and assets and is
          duly qualified to do business and is in good standing in each
          jurisdiction where the failure to so qualify and maintain such good
          standing could reasonably be expected to have a Material Adverse
          Effect;

     (b)  the Parent has full corporate power and authority to execute and
          deliver this Support Agreement and to do all acts and things required
          or contemplated hereunder;

          and delivery of this Support Agreement and the performance by the
          Parent of its obligations hereunder and of the transactions

     (d)  the execution and delivery by the Parent of this Support Agreement and
          the performance by the Parent of its obligations hereunder and of the

          clauses (i) and (iii), contravene, breach, constitute a default under,
          violate or conflict with:

          (i)    the Parent's constating documents or by-laws or any resolution
                 passed by its board of directors or its shareholders;

          (ii)   any Law applicable to the Parent which could reasonably be

                 security agreement, bond, note, contract or other agreement or
                 instrument to which the Parent is a party or by which it or its
                 property is bound, other than any such contravention, breach,
                 default, violation or conflict which could not reasonably be
                 expected to have a Material Adverse Effect; or

          (iv)   any order, writ, judgment, award, injunction or decree binding
                 on the Parent or affecting its properties, other than any such
                 contravention, breach, default, violation or conflict which
                 could not reasonably be expected to have a Material Adverse
                 Effect;

          and do not and will not result in or require the creation of any
          Adverse Claim upon or with respect to any of the Parent's assets;

     (e)  other than the filing of this Support Agreement as required by any
          applicable securities law, no authorization, approval or other action
          by, and no notice to or filing with, any Governmental Authority is
          necessary in connection with the execution and delivery by the Parent
          of this Support Agreement, or the performance by the Parent of its
          obligations hereunder or of the transactions contemplated hereby or to
          give legal effect to the same other than such as have been obtained;

     (f)  this Support Agreement has been duly executed and delivered by the
          Parent;

     (g)  this Support Agreement is a legal, valid and binding obligation of the
          Parent enforceable against the Parent in accordance with its terms by
          King Street, except as enforceability may be limited by applicable
          bankruptcy, insolvency, reorganization, moratorium or similar laws
          affecting the enforcement of creditors' rights generally or by general
          principles of equity;

     (h)  all factual information furnished by or on behalf of the Parent to
          King Street or the Administrator for purposes of, or in connection
          with, this Support Agreement or

<Page>

                                      - 5 -

          the Receivables Purchase Agreement or any transaction contemplated
          hereby is and all other factual information hereafter furnished by or
          on behalf of the Parent to King Street or the Administrator will be,
          true and accurate in all material respects on the date as of which
          such information is dated or certified and (in the case of any such
          information furnished prior to the date hereof) as of the date hereof
          and is not, or shall not be, as the case may be, incomplete by
          omitting to state any material fact necessary to make such information
          not misleading;

     (i)  there are no actions, suits or proceedings existing or pending or, to
          the knowledge of the Parent, threatened against or affecting the
          Parent or any of its property, at law, in equity or before any
          arbitration tribunal or Governmental Authority or alternative dispute
          resolution mechanism which, if adversely determined, could reasonably
          be expected to have a Material Adverse Effect, and the Parent is not
          in default with respect to any Law, which default could reasonably be
          expected to have a Material Adverse Effect;

     (j)  the unaudited consolidated financial statements of the Parent and its
          Subsidiaries for the fiscal quarter ended December 31, 2003 provided
          to King Street fairly present in all material respects the financial
          position of the Parent and its Subsidiaries taken as a whole as at the
          date of such financial statements and the results of its operations
          for the fiscal period ended on such date, and, on the date hereof,
          there has been no material adverse change in the financial position of
          the Parent and its Subsidiaries taken as a whole since such date;

     (k)  no default has occurred and is outstanding under any agreement,
          instrument, indenture or trust deed to which the Parent is a party,
          which default could reasonably be expected to have a Material Adverse
          Effect;

     (l)  no part of the Purchased Interest is subject to any Adverse Claim
          granted or created by the Parent; and

     (m)  on the date of this Support Agreement, the Parent is the direct or
          indirect beneficial owner of all of the issued and outstanding shares
          in the capital of the general partner and each of the limited partners
          of Smurfit-MBI.

     The representations and warranties set forth above shall survive the
     initial purchase of Receivables by King Street pursuant to the Receivables
     Purchase Agreement and shall remain in full force and effect for the
     benefit of King Street.

7.   COVENANTS. The Parent covenants and agrees that, until the Support
     Termination Date, unless King Street shall otherwise consent in writing:

     (a)  PRESERVATION OF CORPORATE EXISTENCE. (i) It will preserve and maintain
          its corporate existence, rights, franchises and privileges in the
          jurisdiction of its incorporation, and qualify and remain qualified in
          good standing as a foreign corporation in each relevant jurisdiction,
          except to the extent that the failure so to preserve and

<Page>

                                      - 6 -

          maintain such rights, franchises, privileges and qualification would
          not materially adversely affect the interests of King Street
          hereunder, or the ability of the Parent to perform its obligations
          hereunder, and (ii) it shall not, other than the proposed amalgamation
          of the Parent and Jefferson Smurfit Corporation (U.S.), Inc. or unless
          otherwise disclosed in writing to King Street on or before the date of
          this Support Agreement, liquidate or dissolve, consolidate or
          amalgamate with any person or sell, transfer or convey all or
          substantially all of its assets;

     (b)  REPORTING REQUIREMENTS. It will furnish to King Street and the Rating
          Agency promptly after same becomes publicly available, copies of all
          periodic and other reports, proxy statements, financial statements and
          other materials (other than (i) the exhibits to registration
          statements and (ii) any registration statements on Form S-8 or its
          equivalent) filed by the Parent with the U.S. Securities and Exchange
          Commission;

     (c)  COMPLIANCE WITH CREDIT AND COLLECTION POLICY. Without limiting its
          obligations hereunder, it will ensure that the Servicer at all times
          complies with the Credit and Collection Policy;

     (d)  COMPLIANCE WITH LAWS. It will comply with all Laws applicable to all
          or any of it, its business, its properties and the Purchased Interest,
          other than any non-compliance that could not reasonably be expected to
          have a Material Adverse Effect;

     (e)  RETAIN CONTROL. It will continue to, either directly or indirectly,
          retain effective control of the Servicer; and

     (f)  BANKRUPTCY PROCEEDINGS. In the event that the Parent seeks protection
          under the Bankruptcy Code of the United States of America, it shall
          (i) ensure that no claim shall be made by the Parent or any of its
          Affiliates that any assets forming part of the Purchased Interest are
          assets of the Parent or the Seller, or that the Purchased Interest or
          any part thereof should be subject to such insolvency proceedings, and
          (ii) provide any assistance required or requested by King Street with
          respect to any action brought by King Street or the Administrator on
          its behalf to release all or any part of the Purchased Interest and
          the transactions contemplated by the Receivables Purchase Agreement
          from any stay of proceedings instituted in connection with such
          insolvency proceedings.

8.   AUTHORIZATION BY PARENT. King Street may continue to purchase Receivables,
     and the Related Security and Collections related thereto, from time to time
     without notice to or authorization from the Parent regardless of the
     Servicer's financial or other condition at the time of any such purchase.
     The Parent acknowledges to King Street that it has adequate means to obtain
     from the Servicer on a continuing basis all information concerning the
     financial condition of the Servicer and the collectibility of the Purchased
     Receivables, and agrees with King Street that King Street shall not have
     any obligation to

<Page>

                                      - 7 -

     disclose or discuss with the Parent any information which King Street has
     respecting the financial condition of Servicer or the collectibility of any
     Purchased Receivables.

9.   TAXES. Any payments to be made by the Parent hereunder shall be made free
     and clear of any deduction, withholding or other Taxes. If the Parent is
     required by law to make any deduction or withholding on account of Taxes or
     otherwise from any such payment, the sum due from it in respect of such
     payment shall be increased to the extent necessary to ensure that after the
     making of such deduction or withholding, King Street receives a net sum
     equal to the sum which it would otherwise have received had no deduction or
     withholding been made, taking into account any credits or setoffs available
     to King Street in respect of such deduction or withholding.

10.  CONTINUING SUPPORT AGREEMENT; ASSIGNMENTS UNDER RECEIVABLES PURCHASE
     AGREEMENT. This Support Agreement is a continuing Support Agreement and
     shall (i) remain in full force and effect until the Support Termination
     Date, (ii) be binding upon the Parent, its successors and assigns, and
     (iii) enure to the benefit of, and be enforceable by, King Street and its
     successors, transferees and assigns. King Street (and any assignee of King
     Street) may at any time assign any and all of its rights hereunder to any
     other person or entity without the consent of the Parent or the Servicer in
     accordance with the provisions of the Receivables Purchase Agreement,
     whereupon (i) each reference herein to King Street shall mean and be a
     reference to such assignee and (ii) such assignee may enforce this Support
     Agreement to the fullest extent as if it were a named party hereto.

11.  AMENDMENTS, WAIVERS, ETC.. No amendment or waiver of any provision of this
     Support Agreement, consent to any departure by any party therefrom or
     approval or direction to be given by any party hereunder shall be effective
     in whole or in part unless the amendment, waiver, consent, approval or
     direction shall be (a) in writing and signed by the Parent and King Street
     and (b) if material, approved by the Rating Agency, and then such waiver,
     consent, approval or direction shall be effective only in the specific
     instance and for the specific purpose for which it was given.

12.  NO WAIVER; REMEDIES. No failure on the part of any party to exercise, and
     no delay in exercising, any right hereunder shall operate as a waiver
     thereof, nor shall any single or partial exercise of any right hereunder
     preclude any other or further exercise thereof or the exercise of any other
     right. The remedies herein provided are cumulative and not exclusive of any
     remedies provided by Law.

13.  TIME OF THE ESSENCE. Time shall be of the essence of this Support Agreement
     and of every provision hereof.

14.  SEVERABILITY. Any provision hereof that is prohibited or unenforceable in
     whole or in part in any jurisdiction shall, as to such provision and such
     jurisdiction, be ineffective to the extent of such prohibition or
     unenforceability without invalidating the remaining provisions of this
     Agreement or affecting the validity or enforceability of such provision in
     any other jurisdiction.

     party, shall do, execute, acknowledge and deliver or cause to be done,
     executed, acknowledged or delivered all such further acts, deeds,
     documents, assignments, transfers, conveyances, powers of attorney and
     assurances as may be reasonably necessary or desirable to effect complete
     consummation of the objects and intent of and the transactions contemplated
     by this Support Agreement.

16.  GOVERNING LAW. This Support Agreement is a contract made under and shall be
     governed by and construed in accordance with the laws of the Province of
     Ontario and the federal laws of Canada applicable in the Province of
     Ontario.

17.  CONSENT TO JURISDICTION; WAIVER OF IMMUNITIES.

     (a)  Each of the parties hereby irrevocably submits to the jurisdiction of
          any court sitting in Toronto in any action or proceeding arising out
          of or relating to this Support Agreement, and each of the parties
          hereby irrevocably agrees that all claims in respect of such action or
          proceeding may be heard and determined in such Toronto court. Each of
          the parties hereby irrevocably waives, to the extent permitted by law,
          the defence of an inconvenient forum to the maintenance of such action
          or proceeding. Each of the parties agrees that a final judgment in any
          action or proceeding shall be conclusive and may be enforced in other
          jurisdictions by suit on the judgment or in any other manner provided
          by Law.

     (b)  Nothing in this Section 17 shall affect (i) the right to serve legal
          process in any other manner permitted by Law, or (ii) the right of any
          party to bring any action or proceeding in the courts of other
          jurisdictions.

     (c)  To the extent that any party has or hereafter may acquire any immunity
          from jurisdiction of any court or from any legal process (whether
          through service or notice, attachment prior to judgment, attachment in
          aid of execution, execution or otherwise) with respect to itself or
          its property, it hereby irrevocably waives, to the extent permitted by
          law, such immunity in respect of its obligations hereunder.

18.  EXECUTION IN COUNTERPARTS. This Support Agreement may be executed in
     counterparts, each of which shall be deemed to be an original and which
     together shall constitute one and the same Support Agreement.
