Project Eagle—Commitment Letter

Ladies and Gentlemen:

You have advised JPMorgan Chase Bank, N.A. (“JPMCB”), Bank of America, N.A. (“Bank of America”), UBS Loan Finance LLC (“UBS”), Deutsche Bank AG New York Branch (“DBNY”), Deutsche Bank AG Cayman Islands Branch (“DB Cayman”) and The Royal Bank of Scotland PLC (“RBS” and, together with JPMCB, Bank of America, UBS, DBNY and DB Cayman, the “Commitment Parties”), J.P. Morgan Securities Inc. (“JPMorgan”), Banc of America Securities LLC (“BAS”), UBS Securities LLC (“UBSS”), Deutsche Bank Securities Inc. (“DBSI”) and RBS Securities Corporation d/b/a RBS Greenwich Capital (“RBSGC” and, together with JPMorgan, BAS, UBSS and DBSI, the “Arrangers” and, together with the Commitment Parties, “we” or “us”) that International Paper Company, a New York corporation (“Borrower” or “you”), proposes to acquire (the “Acquisition”) the containerboard, packaging and recycling business division (the “Acquired Business”) of Weyerhaeuser Company, a Washington corporation (“Seller”). The Acquisition will be effected pursuant to a Purchase Agreement dated as of even date herewith (the “Acquisition Agreement”) between Borrower and Seller. All references to “dollars” or “$” in this agreement and the attachments hereto (collectively, this “Commitment Letter”) are references to United States dollars. All references to “Borrower” or “Borrower and its subsidiaries” for any period from and after consummation of the Acquisition shall include the Acquired Business.

We understand that the sources of funds required to fund the Acquisition consideration and to pay fees, commissions and expenses in connection with the Transactions (as defined below) will include: (A) the senior term loan credit facilities described in the Summary of Principal Terms and Conditions (the “Term Sheet”) attached hereto as Annex I (the “Facilities”); and (B) debt securities issued by the Borrower (the “Notes”) pursuant to a public offering or Rule 144A or other private placement (the “Notes Offering”); it being understood that the aggregate principal amount of the Facilities (as defined herein) made on the Closing Date will be reduced dollar-for-dollar as set forth in the Term Sheet by the aggregate principal amount of Notes issued on or prior to the Closing Date (the Facilities and the Notes Offering are collectively referred to as the “Debt Financing”). No other financing will be required for the uses described above. As used herein, the term “Transactions” means the Acquisition, the Debt Financing and the payments of fees, commissions and expenses in connection with each of the foregoing.

All third-party indebtedness for borrowed money of the Borrower and its subsidiaries (other than the Debt Financing) that is outstanding on the Closing Date (“Existing Indebtedness”) will be repaid, redeemed, defeased or otherwise discharged (or irrevocable notice for the redemption thereof will be given), except for (a) (i) any Existing Indebtedness listed in Schedule A to the Commitment Letter, (ii) any Existing Indebtedness with an outstanding principal amount on the Closing Date no greater than $150 million, so long as the aggregate amount of Existing Indebtedness taken into account pursuant to this clause (ii) does not exceed $200 million and (iii) financings of the Borrower’s subsidiary in Morocco and Borrower’s joint ventures in China and Russia (provided such financings are not guaranteed by the Borrower) (any such indebtedness described in sub-clauses (i), (ii) and (iii) of this clause (a), “Assumed Indebtedness”) and (b) any capital leases of the Borrower and its subsidiaries existing on the Closing Date (“Capital Leases”). After giving effect to the Transactions, the Borrower and its subsidiaries shall have no third-party indebtedness for borrowed money (not including indebtedness incurred or issued pursuant to the Debt Financing), except for the Assumed Indebtedness and any Capital Leases.

Commitments.

You have requested that the Commitment Parties commit to provide the Facilities and that the Arrangers agree to structure, arrange and syndicate the Facilities. Each of JPMCB, Bank of America, UBS, DBNY and RBS is pleased to advise you of its commitment to provide, severally and not jointly, 20%, 20%, 20%, 20% and 20%, respectively, of the Term Loan A Facility to Borrower, and each of JPMCB, Bank of America, UBS, DB Cayman and RBS is pleased to advise you of its commitment to provide, severally and not jointly, 20%, 20%, 20%, 20% and 20%, respectively, of the Term Loan X Facility to Borrower, in each case, upon the terms and subject to the conditions set forth or referred to in this Commitment Letter. Each of the Arrangers is pleased to advise you of its willingness to act as a joint lead arranger and joint bookmanager. The commitments of the Commitment Parties hereunder are subject to the execution and delivery of definitive loan and related agreements and documentation (collectively, the “Bank Documentation”), which shall be (i) in form and substance, and containing such representations, covenants, terms, conditions and other provisions as are, consistent with this Commitment Letter and otherwise substantially similar to the current 5-Year Credit Agreement of the Borrower dated as of March 31, 2006 (the “Current Credit Facility”), with modifications customary for transactions of this type, and (ii) otherwise reasonably satisfactory to us (subject in each case to the section of this Commitment Letter titled “Conditions”). It is acknowledged and agreed that this Commitment Letter sets forth the material terms of the Bank Documentation.

Syndication.

It is agreed that the Arrangers will act as the exclusive advisors, joint lead arrangers and bookmanagers for the Facilities, and, in consultation with you, will exclusively manage the syndication of the Facilities, and will, in such capacities, exclusively perform the duties and exercise the authority customarily associated with such roles. It is further agreed that no additional advisors, agents, co-agents, arrangers or bookmanagers will be appointed and no Lender (as defined below) will receive compensation with respect to any of the Facilities outside the terms contained herein and in the fee letter dated as of the date hereof relating to the Facilities (the “Fee Letter”) in order to obtain its commitment to participate in such Facilities, in each case unless you and we so agree.

The Commitment Parties reserve the right, prior to or after execution of the Bank Documentation, in consultation with you, to syndicate all or a portion of their commitments to one or more institutions that will become parties to the Bank Documentation. Notwithstanding any other provision of this Commitment Letter, no Commitment Party shall, except with the written consent of the Borrower, be relieved or novated from its obligations hereunder in connection with any syndication or assignment until after the Closing Date and, unless the Borrower agrees in writing, each Commitment Party shall (except after the Bank Documentation has been executed but only for so long as it has not been terminated) retain exclusive control over all rights and obligations with respect to its commitment hereunder, including all rights with respect to consents, modifications and amendments, until the Closing Date has occurred and the extensions of credit to be made on such date as contemplated hereby (subject to the conditions herein) have been made. Each Commitment Party acknowledges and agrees that its Commitment is not conditioned upon a successful syndication and that no assignment or assumption by any assignee of any obligations of such Commitment Party in respect of any portion of its Commitment shall relieve such Commitment Party of its obligations hereunder with respect to such portion of the Commitments until the Closing Date has occurred and the extensions of credit to be made on such date as contemplated hereby have been made.

-2-

All aspects of the syndication, including, without limitation, timing, potential syndicate members to be approached, titles, allocations and division of fees, shall be determined by the Arrangers (except as otherwise provided herein and in the Fee Letter) in consultation with you. You agree to, and to use commercially reasonable efforts to cause Seller and the Acquired Business to (including with a covenant to such effect in the Acquisition Agreement), actively assist the Arrangers in such syndication, which the Arrangers may commence as promptly as possible after your acceptance of this Commitment Letter, including by using commercially reasonable efforts to ensure that the syndication efforts benefit materially from your existing lending relationships and to provide the Arrangers, promptly upon request, with all information reasonably deemed necessary by the Arrangers to complete successfully the syndication, including, but not limited to (a) information packages for delivery to potential syndicate members and participants, including at the reasonable request of the Arrangers, a version that does not contain material non-public information concerning you, the Acquired Business or your or its affiliates or any securities of any thereof (the “Confidential Information Memoranda”) and (b) all financial and other information as we may reasonably request with respect to you, the Acquired Business, your subsidiaries and the transactions contemplated hereby, including but not limited to financial projections, forecasts and budgets. You also agree to make available your representatives, and to use commercially reasonable efforts to cause the senior officers and representatives of the Borrower and the Acquired Business, in each case from time to time prior to the earlier of the Successful Syndication (as defined in the Fee Letter) of the Facilities and 90 days after the Closing Date, to be available and to attend and make presentations regarding the business and prospects of the Acquired Business at one or more meetings of prospective lenders and investors at such time and place as the applicable Arrangers may reasonably request. You acknowledge and agree that (i) the Borrower shall use commercially reasonable efforts to cause the initial definitive Confidential Information Memorandum referred to above to be delivered to potential syndicate members as promptly as possible after your acceptance of this Commitment Letter and (ii) the Borrower shall use commercially reasonable efforts to obtain from Standard & Poor’s Ratings Group (“S&P”) and Moody’s Investors Service (“Moody’s”), at its expense, public updates of the ratings of Borrower’s senior unsecured non-credit-enhanced long-term debt securities after giving effect to the Transactions within 21 days after the acceptance by you of this Commitment Letter in accordance with its terms.

You acknowledge that (a) subject to confidentiality arrangements to be agreed upon and to the other provisions of this Commitment Letter, the Arrangers and/or the Agents on your behalf will make available the Confidential Information Memoranda to the proposed syndicate of lenders by posting the Confidential Information Memoranda on IntraLinks or another similar electronic system and (b) certain prospective lenders (such prospective lenders, “Public Lenders”; all other prospective lenders “Private Lenders”) may have personnel that do not wish to receive material non-public information (within the meaning of the United States federal securities laws, “MNPI”) with respect to the Acquired Business or its affiliates or you or your affiliates or any securities of any thereof, and who may be engaged in investment and other market-related activities with respect to such entities’ securities.

Before distribution of any Confidential Information Memoranda to prospective lenders, you agree that you will provide us with a letter in customary form for syndicated loan financings, authorizing the dissemination of the Confidential Information Memoranda. In addition, you agree to use commercially reasonable efforts to cause all materials containing Information that are to be made available to Public Lenders to be clearly and conspicuously marked “PUBLIC” which, at a minimum, shall mean that the word “PUBLIC” shall appear prominently on the first page thereof. You agree that by your marking such materials “PUBLIC”, you shall be deemed to have authorized the Arrangers (subject to applicable confidentiality provisions and to the other provisions of this Commitment Letter) to treat such materials as information that is not MNPI.

-3-

We agree that we will not make any materials that are not marked “PUBLIC” available to Public Lenders, except that, subject to confidentiality arrangements to be agreed upon and to the other provisions of this Commitment Letter, the Arrangers on your behalf may distribute the following documents to all prospective lenders in the form provided to you and to your counsel Debevoise & Plimpton LLP a reasonable time prior to their distribution, unless you or your counsel advise the Arrangers in writing (including by email) within a reasonable time prior to their intended distribution that such material would constitute MNPI and, therefore, should only be distributed to prospective Private Lenders: (a) administrative materials for prospective lenders such as lender meeting invitations and funding and closing memoranda, (b) notifications of changes to the Facilities’ terms and (c) other materials intended for prospective lenders after the initial distribution of the Confidential Information Memoranda, including pro forma financial statements and drafts and final versions of definitive documents with respect to the Facilities (which shall in no event be deemed to constitute MNPI). If you advise us that any of the foregoing items should be distributed only to Private Lenders, then the Arrangers and/or the Agents will not distribute such materials (other than pro forma financial statements and drafts and final versions of definitive documents with respect to the Facilities) to Public Lenders without further discussions with you.

Information.

You hereby represent and covenant that (a) all written information (other than projections, forecasts, budget, estimates and other forward-looking statements (collectively, the “Projections”) and information of a general economic or industry specific nature) that has been or will be made available to us or any of the Lenders by or on behalf of you or the Acquired Business (at your request) in connection with the transactions contemplated hereby (the “Information”), when taken as a whole (and, in the case of information relating to the Acquired Business, to the best of your knowledge; it being understood that Seller has withheld certain customer data, contracts subject to confidentiality obligations with third parties, contracts that contain antitrust-sensitive information of the Acquired Business and other information identified as confidential as of the date hereof in the electronic datasite relating to the Acquired Business), does not and will not, when furnished, contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements contained therein not misleading in the light of the circumstances under which such statements are made and (b) the Projections that have been or will be made available to us or any of the Lenders by or on behalf of you or the Acquired Business (at your request) in connection with the transactions contemplated hereby have been (or, in the case of Projections prepared after the date hereof, will be) prepared in good faith based upon assumptions believed by you to be reasonable at the time of preparation thereof (it being understood that projections by their nature are inherently uncertain and no assurances are being given that the results reflected in the Projections will be achieved). You agree that if at any time prior to the Closing Date any of the representations in the preceding sentence would be incorrect in any material respect if the Information and Projections were being furnished or made available, and such representations were being made, at such time, then you will promptly supplement, or cause to be supplemented, the Information and Projections so that such representations will be correct in all material respects at such time.

Compensation.

As consideration for the commitments of the Lenders hereunder with respect to the Facilities and the agreement of the Arrangers to structure, arrange and syndicate the Facilities and to provide advisory services in connection therewith, you agree to pay, or cause to be paid, the fees set forth in the Term Sheet and the Fee Letter.

Conditions.

The commitment of each Commitment Party hereunder with respect to the Facilities and each Arranger’s agreement to perform the services described herein are subject only to the fulfillment of the following conditions (the “Conditions”): (i) no information (other than Projections and other information of a general economic or industry specific nature) submitted to it in writing prior to the date hereof by or on behalf of Borrower or any of its existing subsidiaries and pertaining to Borrower and its existing subsidiaries is found (x) to contain, taken as a whole, any untrue statement of a material fact or (y) to omit to state a material fact known to the Borrower necessary to make the statements contained therein, taken as a whole, not misleading in the light of the circumstances under which such statements were made, (ii) since the date of the Acquisition Agreement, there shall not have occurred a Business Material Adverse Effect (as defined in the Acquisition Agreement), and (iii) fulfillment of the Clear Markets Condition (as defined below) and the conditions set forth under “Conditions to Borrowing” in the Term Sheet. Notwithstanding anything in this Commitment Letter, the Fee Letter, the Bank Documentation or any other agreement or other undertaking concerning the financing of the Acquisition to the contrary,

(a) the terms of the Bank Documentation shall be in a form such that they do not impair availability of the Facilities on the closing date of the Acquisition (the “Closing Date”) if the Conditions are satisfied; and

(b) the only representations the making of which shall be a condition to availability of the Facilities on the Closing Date shall be the Specified Representations. For purposes hereof, “Specified Representations” means (I) such of the representations made by the Seller with respect to the Acquired Business in the Acquisition Agreement that are material to the interests of the Lenders, but only to the extent that you have the right to terminate your obligations under the Acquisition Agreement as a result of a breach of such representations in the Acquisition Agreement, and (II) the representations and warranties set forth in the Bank Documentation relating to corporate power and authority, the enforceability of the Bank Documentation, Federal Reserve margin regulations, the Investment Company Act of 1940, as amended, and no material conflicts with material agreements.

Notwithstanding the titled “Governing Law” provisions of this Commitment Letter and the Term Sheet, it is understood and agreed that (x) whether any Specified Representation described in clause (b)(I) above has been breached, and whether as a result you have the right to terminate your obligations thereunder, and (y) whether there shall have been a Business Material Adverse Effect shall be determined under the laws of the State of Delaware.

Clear Market.

From the date of this Commitment Letter until the earlier of (i) 90 days after the Closing Date and (ii) our completion of a Successful Syndication (as defined in the Fee Letter) of the Facilities, you will ensure that no debt securities or syndicated loan financing (excluding the Notes Offering, any tax exempt financings in the ordinary course of business consistent with past practice, financings of the Borrower’s subsidiary in Morocco and Borrower’s joint ventures in China and Russia (provided such financings are not guaranteed by the Borrower) and, after September 1, 2008, the refinancing of the €500 million Credit Facility of International Paper Investments (France) S.A.S.) for you or any of your subsidiaries is announced, syndicated or placed without the prior written consent of the Commitment Parties if such financing, syndication or placement would have, in the reasonable judgment of the Commitment Parties, a materially detrimental effect upon the primary syndication of the Facilities (compliance with the foregoing being referred to as the “Clear Markets Condition”).

-5-

Indemnity and Expenses.

You agree to indemnify and hold harmless each of the Arrangers, the Commitment Parties and their respective affiliates and each director, officer, employee, advisor and agent thereof (each, an “indemnified person”) from and against any and all actions, suits, proceedings (including any investigations or inquiries), claims, losses, damages, liabilities or expenses of any kind or nature whatsoever that may be incurred by or asserted against or involve any Arranger, any Commitment Party or any other such indemnified person as a result of or arising out of or in any way related to or resulting from this Commitment Letter and the transactions contemplated hereby, the providing or syndication of the Facilities or the actual or proposed use of proceeds thereof and to pay and reimburse each Arranger, each Commitment Party and each other indemnified person, promptly upon request, for any reasonable legal or other out-of-pocket expenses incurred in connection with investigating, defending or preparing to defend any such action, suit, proceeding (including any inquiry or investigation) or claim (whether or not any Arranger, Commitment Party or other such indemnified person is a party to any action or proceeding out of which any such expenses arise); provided, however, that you shall not have to indemnify any indemnified person against any claim, loss, damage, liability or expense (x) to the extent the same resulted from the gross negligence, bad faith or willful misconduct of the respective indemnified person or any Related Person (as defined below) of such indemnified person (as determined by a court of competent jurisdiction in a final and non-appealable judgment) or (y) arising out of any breach in any material respect by such indemnified person or any Related Person of such indemnified person of this Commitment Letter or any Bank Documentation. No indemnified person seeking indemnification or reimbursement under this Commitment Letter will, without your prior written consent (not to be unreasonably withheld or delayed), settle, compromise, consent to the entry of any judgment in or otherwise seek to terminate any action, suit, proceeding (including any inquiry or investigation) or claim referred to above. Notwithstanding the immediately preceding sentence, if at any time an indemnified person shall have requested that you reimburse such indemnified person for legal or other expenses in connection with investigating, responding to or defending any such action, suit, proceeding (including any inquiry or investigation) or claim referred to herein, you shall be liable for any settlement of any action effected without your written consent if (a) such settlement is entered into more than 30 days after receipt by you of such request for reimbursement and (b) you shall not have reimbursed such indemnified person in accordance with such request prior to the date of such settlement. You shall not, without the prior written consent of any indemnified person, effect any settlement of any pending or threatened proceeding in respect of which such indemnified person is or could reasonably be expected to have been a party and indemnity could reasonably be expected to have been sought hereunder by such indemnified person, unless such settlement includes an unconditional release of such indemnified person from all liability or claims that are the subject matter of such proceeding. For purposes hereof, a “Related Person” of an indemnified person means any of its affiliates or any of its or its affiliates’ directors, officers, employees, advisors and agents. None of the Arrangers, the Commitment Parties or any other indemnified person shall be responsible or liable to you or any other person for any indirect, consequential or punitive damages which may be alleged as a result of this Commitment Letter or the financing contemplated hereby. In addition, you hereby agree that all reasonable and documented out-of-pocket costs and expenses (including the reasonable fees and expenses of one firm of counsel with respect to the Facilities and one local counsel per jurisdiction) of the Commitment Parties, the Agents, the Arrangers and their respective affiliates arising in connection with this Commitment Letter and in connection with the transactions described herein shall be reimbursed by you solely in the event that the Acquisition or an Alternate Transaction (as defined in the Fee Letter) is consummated; provided that upon termination or expiration of this Commitment Letter you agree to pay such reasonable fees and expenses of Cahill Gordon & Reindel LLP whether or not the Acquisition or an Alternate Transaction is consummated. Any reimbursement hereunder shall be without duplication of any reimbursement to the Commitment Parties, the Agents, the Arrangers and their respective affiliates under any other agreement. Notwithstanding any other provision of this Commitment Letter, no indemnified person shall

-6-

be liable for any damages arising from the use by others of information or other materials obtained through electronic telecommunications or other information transmission systems, except to the extent the same resulted from the gross negligence, bad faith or willful misconduct of such indemnified person or any Related Person of such indemnified person (as determined by a court of competent jurisdiction in a final and non-appealable judgment).

Confidentiality.

You agree that, unless the Arrangers have otherwise consented (such consent not to be unreasonably withheld, conditioned or delayed), neither this Commitment Letter, the Fee Letter nor the terms hereof or thereof will be disclosed by you to any person or entity except that this Commitment Letter and the Fee Letter (but, in the case of the Fee Letter, only as contemplated in clauses (i), (ii) (to the extent the provisions thereof relating to fees payable to the Arrangers and Agents and other pricing related terms have been redacted in a manner reasonably satisfactory to the Arrangers), (iv) and (v) of this sentence) may be disclosed to (i) to your officers, directors, employees, accountants, agents, attorneys and other advisors, and then only on a “need to know” confidential basis, (ii) the Seller and its affiliates, officers, directors, employees, agents, accountants, attorneys and other advisors, (iii) to any actual or prospective Lender or any actual or prospective lender or investor in connection with any of the Transactions, any of their respective affiliates, and any of the respective partners, officers, directors, employees, agents, accountants, attorneys and other advisors of any of the foregoing, (iv) to the extent necessary in connection with the exercise of any remedy or enforcement of any right hereunder, (v) as may be compelled to be disclosed in, or necessary to the defense of, any litigation or a judicial or administrative proceeding or as otherwise required by law, (vi) in any public or regulatory filing or in any proxy statement, prospectus, offering memorandum or offering circular in connection with any of the Transactions, and (vii) to Moody’s, S&P or any other ratings agency in connection with obtaining a rating of any of the Facilities and/or the Notes.

You acknowledge and agree that we and/or our affiliates may be requested to provide additional services with respect to Borrower, the Acquired Business and/or their respective affiliates or other matters contemplated hereby. Any such services will be set out in and governed by a separate agreement(s) (containing terms relating, without limitation, to services, fees and indemnification) in form and substance satisfactory to the parties thereto. Nothing in this Commitment Letter is intended to obligate or commit us or any of our affiliates to provide any services other than as set out herein.

We hereby expressly disclaim any fiduciary or similar obligations to any such person, either in connection with the Facilities or this Commitment Letter or any matters leading up to either, and you hereby confirm your understanding and agreement to that effect. Each of you and we agree that you and we are each responsible for making our own independent judgments with respect to the Facilities, and that any opinions or views expressed by us to you regarding such transactions do not constitute advice or recommendations to you or any of your subsidiaries. You, on behalf of yourself and your subsidiaries, hereby waive and release, to the fullest extent permitted by law, any claims that you or any of your subsidiaries may have against us with respect to any breach or alleged breach of any fiduciary or similar duty in connection with the transactions contemplated by this Commitment Letter or any matters leading up to the execution of this Commitment Letter or the Bank Documentation.

Governing Law, Etc.

This Commitment Letter and the commitment of the Lenders shall not be assignable by you without the prior written consent of us and the Lenders, and any purported assignment without such consent shall be void. We reserve the right to employ the services of our affiliates in providing services contemplated by this Commitment Letter and to allocate, in whole or in part, to our affiliates certain fees payable to us in such manner as we and our affiliates may agree in our sole discretion. You also agree that the Commitment Parties may at any time and from time to time assign all or any portion of their respective commitments hereunder to one or more of their respective affiliates provided that no Commitment Party shall be relieved of any portion of its commitments hereunder prior to the initial funding under the Facilities.

The Acquisition shall be consummated concurrently with the initial funding of the Facilities substantially in accordance with the Acquisition Agreement without any waiver or amendment thereof, or consent thereunder, that is materially adverse to the Lenders unless consented to by the Commitment Parties (which consent shall not be unreasonably withheld or delayed, it being understood that Borrower may waive the Marketing Period (as defined in the Acquisition Agreement) in its sole discretion).
