Exhibit 10.1

INTERNATIONAL PAPER COMPANY

PENSION RESTORATION PLAN

FOR

SALARIED EMPLOYEES

Effective April 1, 1991

Amended and Restated Effective January 1, 2009

409A Amendments Effective January 1, 2005

PREAMBLE

The purpose of this International Paper Company Pension Restoration Plan for Salaried Employees (the “Plan”) is to provide for the payment of supplemental pension benefits, out of the general assets of International Paper Company (the “Company”), to an eligible salaried employee in situations where such employee’s full accrued pension benefits cannot be paid out of the trust established under the tax-qualified retirement plan or plans sponsored by the Company or any of its subsidiaries in which such employee participates because of statutory limitations imposed by Internal Revenue Code Sections 415 and 401(a)(17) and other statutes and regulations.

The portion of this unfunded plan which provides benefits solely as a result of the impact of Internal Revenue Code Section 415 is an “excess benefit plan” as defined in Section 3 (36) of the Employee Retirement Income Security Act of 1974, as amended (and related provisions of the Internal Revenue Code of 1986, as amended). The Plan was authorized, effective April 1, 1991, by a resolution of the Board of Directors of the Company dated April 9, 1991.

Effective January 1, 1993, the Plan was amended to recognize compensation deferred under a non-qualified savings plan of the Company or its United States subsidiaries and awards deferred under the Company’s Management Incentive Plan.

Effective January 1, 2005, the Plan was amended to the extent necessary to incorporate the requirements of Internal Revenue Code Section 409A (“409A Amendments”). Participants whose benefits under this Plan commence before January 1, 2009, or who terminate employment with a vested benefit under this Plan prior to January 1, 2005, shall have their benefits determined under this Plan as in effect prior to such 409A Amendments.

CALCULATION OF BENEFIT AMOUNT

TIME AND FORM OF PAYMENT

4.01 Form of Benefit Payment. Notwithstanding Section 4.05, an Eligible Participant may elect in writing, prior to the commencement of benefit payments required in Section 4.04, any of the forms of benefit payment under this Plan as listed on Appendix A, as it may be amended from time to time. Once benefit payments commence under this Section 4.01 or under Section 4.05, whichever is applicable, the form of payment is irrevocable and cannot be changed during retirement, except as provided under Section 5.06 in the case of an Eligible Participant who is not located by his Mandatory Payment Date and the Plan is later notified that his death occurred prior to the Mandatory Payment Date.

4.02 Spousal Consent Not Required for Married Participants. A married Eligible Participant shall not be required to obtain consent of his spouse in order to elect an optional form of payment provided in Section 4.01.

4.03 Designated Retirement Date. This Section 4.03 shall apply to any Eligible Participant whose retirement commences after December 31, 2008 and whose employment terminates after December 31, 2004. Each such Eligible Participant shall have a Designated Retirement Date for purposes of the Plan. The Designated Retirement Date shall be based on years of Vesting Service, as such term is defined in the Pension Plan, and shall be as follows:

A. For Eligible Participants who have completed ten or more years of Vesting Service, the Designated Retirement Date shall mean the latest of (i) January 1, 2009, (ii) the first of the month coinciding with or next following attainment of age 55, or (iii) the first of the month immediately following the Eligible Participant’s termination of employment with the Company.

B. For Eligible Participants who have not completed ten or more years of Vesting Service, the Designated Retirement Date shall mean the latest of (i) January 1, 2009, (ii) the first of the month coinciding with or next following attainment of age 65, or (iii) the first of the month immediately following the Eligible Participant’s termination of employment with the Company.

C. For Eligible Participants who qualify for early retirement as a result of bridging to early retirement eligibility under the Severance Bridging provision set forth in a Benefit Schedule of the Pension Plan (at least age 53 and completed eight years of Vesting Service), the Designated Retirement Date shall mean the later of (i) January 1, 2009, or (ii) the first of the month immediately following the Eligible Participant’s termination of employment with the Company.

4.04 Mandatory Payment Date. For any Eligible Participant whose employment terminates after December 31, 2004 and whose retirement commences after December 31, 2008, the benefit payable under Article III shall commence no later than the Mandatory Payment Date which is the later of (i) December 31 of the year of the Eligible Participant’s Designated Retirement Date, or (ii) the date 2  ¹/2 months following the Designated Retirement Date. If the payment to the Eligible Participant commences

after his Designated Retirement Date, the payment as of the actual benefit commencement date shall include the amount of the missed payments from the Designated Retirement Date, plus interest.

4.05 Default Form of Benefit Payment. The default form of payment is a 20—year Certain and Life Annuity, with the Eligible Participant’s estate as beneficiary. An Eligible Participant’s benefit shall be paid in the default form absent an election under Section 4.01 by the Eligible Participant’s Mandatory Payment Date.

4.06 Required Delay for Specified Employees. Notwithstanding Section 4.04, if the benefit becomes payable due to an Eligible Participant’s termination of employment and such Eligible Participant is a Specified Employee, payment of such benefit shall be made or commence on the first day of the seventh month immediately following the Eligible Participant’s termination of employment if such date is later than the date such amounts would otherwise be paid or commence to be paid. If the payment to the Eligible Participant commences after his Designated Retirement Date, the payment as of the actual benefit commencement date shall include the amount of the missed payments from the Designated Retirement Date, plus interest.

4.07 Pre-Retirement Surviving Spouse’s Benefit. In the event an Eligible Participant dies before his Designated Retirement Date, if his spouse is eligible for a pre-retirement survivor annuity under the Pension Plan, the Eligible Participant’s spouse shall be entitled to a monthly benefit from the Plan determined in the same manner as such pre-retirement survivor annuity based on the Eligible Participant’s benefit amount determined under Section 3.01. The Pre-Retirement Surviving Spouse’s Benefit shall commence on the Eligible Participant’s Designated Retirement Date. Notwithstanding the foregoing, in the event an Eligible Participant has not commenced benefits under the Plan, and dies on or after his Designated Retirement Date and before his Mandatory Payment Date, the Pre-Retirement Surviving Spouse’s Benefit shall be payable to the Eligible Participant’s spouse.

GENERAL PROVISIONS

5.01 Administration of Plan. The Plan Administrator of this Plan shall be the Director, Global Compensation and Benefits of the Company. This Plan shall be administered by the Plan Administrator who shall have discretion to interpret the provisions of the Plan, to determine the amount of benefits payable under the Plan, and to decide any questions or disputes arising under the Plan. All such decisions made by the Plan Administrator shall be final and binding on the Company, its subsidiaries, the Eligible Participants and their heirs or beneficiaries.

5.02 Amendment or Termination of Plan. The Company reserves the right to amend, modify or terminate this Plan at any time by authority of its Board of Directors, provided that such action shall not adversely affect any Eligible Participant’s rights to a benefit which has become payable pursuant to the provisions of this Plan prior to such action.

5

5.03 Termination of Employment. Nothing contained in this Plan shall be construed as a contract of employment between the Company or a subsidiary and any Eligible Participant, or as a right of any Eligible Participant to be continued in employment of the Company or a subsidiary, or as a limitation on the right of the Company or a subsidiary to discharge any of its employees, with or without cause.

5.04 Benefit Not Assignable. An Eligible Participant’s rights under this Plan shall not be subject to assignment, encumbrance, garnishment, attachment or charge (whether voluntary or involuntary), and, in the event of any such assignment, action or proceeding, any benefit otherwise payable under this Plan shall be deemed terminated or forfeited.

5.05 Payment of FICA Taxes. At the time Federal Insurance Contributions Act (“FICA”) taxes become due and payable by an Eligible Participant on his benefit under the Plan, such FICA taxes shall be paid from the Plan as follows:

A. If FICA taxes are payable in the same calendar year that payment of the benefit commences under Section 4.04, the FICA taxes shall be withheld from the benefit paid in that calendar year and remitted on behalf of the Eligible Participant to the U.S. Treasury; or

B. If FICA taxes are payable in a calendar year prior to the calendar year that payment of the benefit commences under Section 4.04, the amount of the FICA taxes and any corresponding federal, state or local income tax withholding shall be paid from the Plan on behalf of the Eligible Participant to the U.S. Treasury and applicable tax authorities, and the Eligible Participant’s benefit shall be reduced by the amount of these tax payments.

5.06 Disputed Claims. In the event an Eligible Participant is not located and does not make a valid benefit election by his Mandatory Payment Date, then the amount of benefits payable under this Plan from such Mandatory Payment Date shall be reported to the IRS as income to the Eligible Participant and shall be paid to the Eligible Participant once he notifies the Plan of his whereabouts. In the event the Plan is notified that the Eligible Participant died prior to his Mandatory Payment Date, the Plan will correct the tax reporting to the IRS and, if applicable, will pay the Pre-Retirement Surviving Spouse’s Benefit to the Eligible Participant’s spouse.
