     SECTION 1. Amendment to the Credit Agreement. The definition of the term

     SECTION 4. Representations and Warranties. To induce the other parties
hereto to enter into this Amendment, the Borrower represents and warrants to
each other party hereto that, after giving effect to this Amendment, (a) the
representations and warranties set forth in Article IV of the Credit Agreement

     SECTION 6. Amendment Fee. The Borrower agrees to pay to each Lender (an

(a) in order to receive such Amendment Fee, (i) if the Approving Lender is an
Affiliate of any other Lender under the Credit Agreement, all such Affiliated

not more than one Amendment Fee (i.e., not more than $5,000 in the aggregate)
shall be payable hereunder and under the SLP Amendment to any Lender or group
of Affiliated Lenders. As used in this Section 6, the term "Affiliate" and the
correlative term "Affiliated" shall have the meaning assigned in the Credit
Agreement. The Amendment Fee payable to an Approving Lender (or group of
Affiliated Approving Lenders) shall be paid to the Administrative Agent for the
account of such Lender or group, shall be paid in immediately available funds
and once paid, shall not be refundable under any circumstances, provided that

waiver of, or otherwise affect the rights and remedies of the Lenders, the
Agents, the Administrative Agent, the Collateral Agent, the Facing Agent, the
Swingline Lender or the Borrower under the Credit Agreement or any other Loan
Document, and shall not alter, modify, amend or in any way affect any of the
terms, conditions, obligations, covenants or agreements contained in the Credit
Agreement or any other Loan Document, all of which are ratified and affirmed in

be deemed to entitle the Borrower to a consent to, or a waiver, amendment,
modification or other change of, any of the terms, conditions, obligations,
covenants or agreements contained in the Credit Agreement or any other Loan
Document in similar or different circumstances. This Amendment shall apply and
be effective only with respect to the provisions of the Credit Agreement
specifically referred to herein. After the date hereof, any reference to the
Credit Agreement shall mean the Credit Agreement, as modified hereby. This
Amendment shall constitute a Loan Document for all purposes of the Credit
Agreement and the other Loan Documents.

     SECTION 8. Counterparts. This Amendment may be executed in any number of
counterparts and by different parties hereto in separate counterparts, each of
which when so executed and delivered shall be deemed an original, but all such
counterparts constitute but one and the same instrument. Delivery of any
executed counterpart of a signature page of this Amendment by facsimile
transmission shall be effective as delivery of a manually executed counterpart
hereof.

     SECTION 9. Applicable Law. THIS AMENDMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

                    AMENDMENT NO. 1, dated as of May 1, 2001 (this
               "Amendment"), to the Credit Agreement dated as of May 31, 2000
               (as amended, restated, supplemented or otherwise modified from
               time to time, the "Agreement"), among Stone Container
               Corporation, a Delaware corporation ("Stone"), St. Laurent
               Paperboard Inc., a corporation amalgamated under the Canada
               Business Corporations Act and a wholly owned subsidiary of Stone
               ("Canco" and, together with Stone, the "Borrowers"), the Lenders
               (as defined in Article I of the Agreement), The Chase Manhattan
               Bank, a New York banking corporation ("Chase") as Agent, Bankers
               Trust Company, a New York banking corporation ("BTCo"), as
               administrative agent for the Lenders (the "Administrative
               Agent"), and as collateral agent for the Lenders (the
               "Collateral Agent"), the Facing Agent (as defined in Article I
               of the Agreement), and Deutsche Bank Canada, a Chartered Bank
               pursuant to Schedule II of the Bank Act, as Canadian
               administrative agent (the "Canadian Administrative Agent") for
               the Revolving Lenders (as defined in Article I of the
               Agreement)(capitalized terms used but not otherwise defined
               herein shall have the meanings assigned to them in the
               Agreement).

          WHEREAS, pursuant to the terms and subject to the conditions
contained in the Agreement, the Lenders have extended, and have agreed to
extend, credit to the Borrowers; and

          WHEREAS, the Borrower has requested that Section 4.15 of the
Agreement be modified in the manner provided for in this amendment, and the
Lenders are willing to amend the Agreement as requested by the Borrower,
subject to the terms and conditions hereinafter set forth.

          NOW THEREFORE, in consideration of the mutual agreements herein
contained and other good and valuable consideration, the sufficiency and
receipt of which are hereby acknowledged, the parties hereto agree as follows:

          SECTION 1.  Amendment.  Section 4.15 of the Agreement is hereby
amended and restated in its entirety as set forth below:

             "SECTION 4.15.  Employee Benefit Plans.  (a) Each Borrower and
     their respective ERISA Affiliates is in compliance in all material
     respects with the applicable provisions of ERISA and the Code and the
     regulations and published interpretations thereunder.  No Reportable Event
     has occurred in respect of any Plan of either Borrower or any ERISA
     Affiliate.  The present value of all benefit liabilities of all
     underfunded Plans (based on those assumptions used to fund each such Plan)
     did not, as of the last annual valuation dates applicable thereto, exceed
     the value of the assets of the Plans by an amount that could reasonably be
     expected to result in a Material Adverse Effect.  No Plan of either
     Borrower or any ERISA Affiliate is reasonably likely to have an unfunded
     benefit liability that could result in a Material Adverse Effect.  Neither
     Borrower nor any ERISA Affiliate has incurred any Withdrawal Liability
     that could result in a Material

<PAGE>

     Adverse Effect.  Neither Borrower nor any ERISA Affiliate has received any
     notification that any Multiemployer Plan is in reorganization or has been
     terminated within the meaning of Title IV of ERISA and no Multiemployer
     Plan is reasonably expected to be in reorganization or to be terminated
     where such reorganization or termination has resulted or could reasonably
     be expected to result, through increases in the contributions required to
     be made to such Plan or otherwise, in a Material Adverse Effect.

          (b) The Canadian Pension Plans are duly registered under the ITA and
     any other applicable laws which require registration, have been
     administered in all material respects in accordance with the ITA and such
     other applicable laws and no event has occurred which could reasonably be
     expected to cause the loss of such registered status.  All material
     obligations of Canco and each of its Subsidiaries required to be performed
     by Canco or its Subsidiaries in connection with the Canadian Pension Plans
     and the funding agreements therefor have been performed on a timely basis.
      As of the Closing Date, there are no outstanding disputes concerning the
     assets of the Canadian Pension Plans or the Canadian Benefit Plans.  No
     promises of benefit improvements under the Canadian Pension Plans or the
     Canadian Benefit Plans have been made except where such improvement could
     not reasonably be expected to have a Material Adverse Effect.  All
     contributions or premiums required to be made or paid by Canco and each of
     its Subsidiaries to the Canadian Pension Plans or the Canadian Benefit
     Plans have been made on a timely basis in accordance with the terms of
     such plans and all applicable laws.  There have been no improper
     withdrawals or applications of the assets of the Canadian Pension Plans or
     the Canadian Benefit Plans.  None of the Canadian Pension Plans or the
     Canadian Benefit Plans has any unfunded actuarial liabilities or solvency
     deficiencies (within the meaning of the Quebec Supplemental Pension Plans
     Act) in an aggregate amount that could reasonably be expected to result in
     a Material Adverse Effect."

          SECTION 2.  Representations and Warranties. To induce the other
                      ------------------------------
parties hereto to enter into this Amendment, each Borrower represents and
warrants to each of the Lenders, the Administrative Agent, the Agents, the
Facing Agent, the Collateral Agent and the Canadian Administrative Agent that,
after giving effect to this Amendment, (a) the representations and warranties
set forth in Article IV of the Agreement are true and correct in all material
respects on and as of the date hereof, except to the extent such representations
and warranties expressly relate to an earlier date, and (b) no Default or Event
of Default has occurred and is continuing.

          SECTION 3.  Conditions to Effectiveness. This Amendment shall become
                      ---------------------------
effective on the date on which the Agents shall have received counterparts of
this Amendment that, when taken together, bear the Borrowers and the Required
Lenders signature.

          SECTION 4.  Effect of Amendment.  Except as expressly set forth
                      -------------------
herein, this Amendment shall not by implication or otherwise limit, impair,
constitute a waiver of, or otherwise affect the rights and remedies of the
Lenders, the Administrative Agent, the Agents, the Facing Agent, the Collateral
Agent, the Canadian Administrative Agent, the Borrower or the Guarantors under
the Agreement or any other Loan Document, and shall not alter, modify, amend or
in any way affect any of the terms, conditions, obligations, covenants or
agreements contained in the Agreement or any other Loan Document, all of which
are ratified and affirmed in all respects and shall continue in full force and
effect. Nothing herein shall be deemed to entitle the Borrowers or the
Guarantors to a consent to, or a waiver, amendment, modification or other change
of, any of the terms, conditions, obligations, covenants or agreements contained
in the Agreement or any other Loan Document in similar or different
circumstances.

          SECTION 5.  Counterparts.  This Amendment may be executed in any
                      ------------

each of which when so executed and delivered shall be deemed an original, but
all such counterparts constitute but one and the same instrument. Delivery of
any executed counterpart of a signature page of this Amendment by facsimile
transmission shall be effective as delivery of a manually executed counterpart
hereof.

          SECTION 6.  APPLICABLE LAW.  THIS AMENDMENT SHALL BE GOVERNED BY, AND
                      --------------
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

          SECTION 7.  Headings.  The headings of this Amendment are for purposes
