This Time Sharing Agreement (the Agreement), is made and entered into this 1st day of May, 2024, by and between International Paper Company, a New York corporation (“Operator” or the “Company”), and Andrew K. Silvernail, chief executive officer of the Company, with a primary residence in Memphis, Tennessee (“User”).

WHEREAS, Operator owns and operates the aircraft (collectively, the “Aircraft”) listed on Schedule A hereto for business use by employees and non-employee directors of the Company in accordance with Part 91 of the Federal Aviation Regulations and the Company’s policy regarding the use of corporate aircraft (the “Aircraft Policy”); and

WHEREAS, Operator has the right and lawful authority to enter into time sharing agreements, as provided in §91.501 of the Federal Aviation Regulations (“FARs”) to provide its senior executives with personal travel consistent with the Company’s Aircraft Policy; and

WHEREAS, Operator has agreed to make the Aircraft, with flight crew, when the Aircraft and flight crew are not otherwise needed for business purposes, available to User for User’s personal travel in accordance with the Aircraft Policy on a non-exclusive time-sharing basis in accordance with §91.501 of the FARs; and

WHEREAS, the User agrees to reimburse the Operator for all personal use of the Aircraft as permitted under the FARs and as pursuant to the terms of this Agreement, which sets forth the understanding of the parties.

NOW THEREFORE, Operator and User declaring their intention to enter into and be bound by this Agreement, and for the good and valuable consideration set forth below, hereby covenant and agree as follows:

1.Provision of Aircraft and Crew. Subject to Aircraft availability, Operator agrees to provide to User the Aircraft and flight crew on a time sharing basis in accordance with the provisions of FAR Part 91, including §§ 91.501(b)(6), 91.501(c)(1) and 91.501(d) of the FARs. Operator shall provide, at its sole expense, qualified flight crew for all flight operations under this Agreement. If Operator is no longer the operator of any of the Aircraft, Schedule A shall be deemed amended to delete any reference to such Aircraft and this Agreement shall be terminated as to such Aircraft but shall remain in full force and effect with respect to each of the other Aircraft identified thereon, if any. No such termination shall affect any of the rights and obligations of the parties accrued or incurred prior to such termination. If Operator becomes the operator of any aircraft not listed on Schedule A hereto, Schedule A shall be modified to include such aircraft as an Aircraft covered by this Agreement, and thereafter this Agreement shall remain in full force and effect with respect to such Aircraft and each of the other Aircraft identified thereon, if any.

2.Term. The term of this Agreement (the “Term”) shall commence on the date hereof and shall continue until terminated by either party on written notice to the other party, such termination to become effective 30 days from the date of the notice, provided that this Agreement may be terminated by Operator on such shorter notice as may be required for Operator to comply with applicable law,

regulations, the requirements of any financial institution with a security or other interest in the Aircraft, insurance requirements, or in the event the insurance required hereunder is not in full force and effect. This Agreement shall terminate immediately in the event that User is no longer either the Chief Executive Officer or the Chairman of the Board of International Paper Company. Notwithstanding the foregoing, any provisions directly or indirectly related to User’s payment obligations for flights completed prior to the date of termination and the limitation of liability provisions in Section 10 shall survive the termination of this Agreement.

3.Reimbursement of Expenses. For each Trip or Round Trip (as such terms are defined below) conducted under this Agreement, User shall pay Operator an amount (as determined by Operator) equal to the actual expenses of operating such Trip (not to include non-occupied legs, or “dead-head” flights, needed by Operator to position the aircraft for business use), not to exceed the sum of the following expenses as permitted pursuant to FAR 91.501(d), in excess of the amount allowed pursuant to the Term and Conditions of Offer of Employment letter dated March14, 2024, as may be amended from time to time by the Board of Directors of the Company:

(a)Fuel, oil, lubricants, and other additives;

(b)Travel expenses of the crew, including food, lodging, and ground transportation;

(c)Hangar and tie-down costs away from the Aircraft’s base of operation;

(d)Insurance obtained for the specific flight as per Section 8.(b);

(e)Landing fees, airport taxes, and similar assessments;

(f)Customs, foreign permit, and similar fees directly related to the flight;

(g)In-flight food and beverages;

(h)Passenger ground transportation;

(i)Flight planning and weather contract services; and

(j)An additional charge equal to one hundred percent (100%) of the expenses listed in subsection (a) above.

The term “Trip” shall mean a flight from a departure point to a single destination. A “Round Trip” shall mean a flight from a departure point to one destination and back to the same departure point. In the event that User travels from a departure point to multiple destinations, the Operator will provide a separate invoice for each Trip.

4.Invoicing and Payment. All payments to be made to Operator by User hereunder shall be paid in the manner set forth in this Section 4. Operator will pay, or cause to be paid, all expenses related to the operation of the Aircraft hereunder in the ordinary course. Within 30 days of the end of each Trip or Round Trip, Operator shall provide or cause to be provided to User an invoice showing all personal use of the Aircraft by User pursuant to this Agreement during that Trip or Round Trip and a complete accounting detailing all amounts that are payable by User pursuant to Section 3 for that Trip or Round Trip (plus applicable domestic or international air transportation excise taxes, and any other fees, taxes or

charges assessed on passengers by and remitted to a government agency or airport authority). User shall pay all amounts due under the invoice in a manner reasonably acceptable to Operator not later than 30 days after receipt thereof. In the event Operator has not received all supplier invoices for reimbursable charges relating to such Trip or Round Trip prior to such invoicing, Operator shall issue a supplemental invoice(s) for such charge(s) to User, and User shall pay each supplemental invoice within 30 days after receipt thereof.

5.Flight Requests. User shall provide the Operator’s Aviation Department with Trip requests for User’s personal travel to be undertaken pursuant to this Agreement and proposed flight schedules as far in advance of User’s desired departure as possible, and at least 24 hours prior to User’s planned departure or as may be required by law. The advance notice requirement in this Section 5 may be waived by Operator in its discretion. All flight requests for travel under this Agreement shall be in accordance with all reasonable policies established by Operator. Flight requests shall be in writing on a form that is provided by the Operator to the User. Operator shall have sole and exclusive authority over the scheduling of the Aircraft. Operator shall not be liable to User or any other person for loss, injury, or damage occasioned by the delay or failure to furnish the Aircraft and crew pursuant to this Agreement for any reason. In addition to requested schedules and departure times, User shall provide at least the following information for each proposed flight reasonably in advance of the desired departure time as required by Operator or its flight crew:

(a)departure point;

(b)destination;

(c)date and time of flight;

(d)number and identity of anticipated passengers;

(e)nature and extent of luggage and/or cargo expected to be carried;

(f)date and time of return flight, if any; and

(g)any other information concerning the proposed flight that may be pertinent to or required by Operator, its flight crew, or governmental entities.

6.Operational Authority and Control.

(a)Operator shall be responsible for the physical and technical operation of the Aircraft and the safe performance of all flights under this Agreement, and shall retain full authority and control, including exclusive operational control and exclusive possession, command and control of the Aircraft for all flights under this Agreement.

(b)Operator shall furnish at its expense a fully qualified flight crew with appropriate credentials to conduct each flight undertaken under this Agreement and included on the insurance policies that Operator is required to maintain hereunder. In accordance with applicable FARs, the qualified flight crew provided by Operator will exercise all required and/or appropriate duties and responsibilities in regard to the safety of each flight conducted hereunder. The pilot-in-command shall have absolute discretion in all matters concerning the preparation of the Aircraft for flight and the flight itself, the load carried and its distribution, the decision whether or not a flight shall be undertaken, the route to be flown,

the place where landings shall be made, and all other matters relating to operation of the Aircraft. User specifically agrees that the flight crew shall have final and complete authority to delay or cancel any flight for any reason or condition that in the sole judgment of the pilot-in-command could compromise the safety of the flight, and to take any other action that in the sole judgment of the pilot-in-command is necessitated by considerations of safety. No such action of the pilot-in-command shall create or support any liability to User or any other person for loss, injury, damage or delay. Operator’s operation of the Aircraft hereunder shall be strictly within the guidelines and policies established by Operator and FAR Part 91.

(c)Subject to Aircraft and crew availability, Operator shall use its good faith efforts, consistent with its approved policies, to accommodate User’s needs and avoid conflicts in scheduling. Although every good faith effort shall be made to avoid its occurrence, any flights scheduled under this Agreement are subject to cancellation by either party without incurring liability to the other party. In the event of a cancellation, the canceling party shall provide the maximum notice reasonably practicable.

(d)In the absence of another flight scheduled on the aircraft by User or another scheduled business trip, the aircraft may remain at the destination until its next required use. If the next use of the aircraft is a business use, the Operator shall not charge the User for expenses associated with Hangar and tie-down costs away from the Aircraft’s base of operation; if, however, the next use of the Aircraft is by User (personal), the Operator shall have the option of returning the aircraft to its base of operations or permitting it to remain at the destination. In either event, the User shall pay for the associated costs.

7.Aircraft Maintenance. Operator shall, at its own expense, cause the Aircraft to be inspected, maintained, serviced, repaired, overhauled, and tested in accordance with FAR Part 91 so that the Aircraft will remain in good operating condition and in a condition consistent with its airworthiness certification and shall take such requirements into account in scheduling the Aircraft hereunder, including but not limited compliance with applicable airworthiness directives and service bulletins. Performance of maintenance, preventive maintenance or inspection shall not be delayed or postponed for the purpose of scheduling the Aircraft unless such maintenance or inspection can safely be conducted at a later time in compliance with applicable laws, regulations and requirements, and such delay or postponement is consistent with the sound discretion of the pilot-in-command. In the event that any non-standard maintenance is required during the term and will interfere with User’s requested or scheduled flights, Operator, or Operator’s pilot-in-command, shall notify User of the maintenance required, the effect on the ability to comply with User’s requested or scheduled flights and the manner in which the parties will proceed with the performance of such maintenance and conduct of such flight(s). In no event shall Operator be liable to User or any other person for loss, injury or damage occasioned by the delay or failure to furnish the Aircraft under this Agreement, whether or not maintenance-related.

8.Insurance.

(a)Operator, at its expense, will maintain or cause to be maintained in full force and effect throughout the Term of this Agreement an aviation liability and hull insurance policy including: aviation liability insurance against bodily injury and property damage claims arising out of the use of the Aircraft in an amount not less than $200 Million for each occurrence; and hull insurance for the Aircraft in amounts determined by Operator at its sole discretion. The aviation liability coverage shall include User as an insured, and include a severability of interest provision providing that the insurance shall apply separately to each insured against whom a claim is made, except as respects the limits of liability. The aviation liability and hull insurance coverage shall include provisions whereby the insurer(s) waive all

rights of subrogation they may have or acquire against User and shall permit the use of the Aircraft by Operator for compensation or hire as provided in §91.501 of the FARs.

(b)Operator shall use reasonable commercial efforts to provide such additional insurance for specific flights under this Agreement as User may reasonably request. User acknowledges that any trips scheduled to areas not currently covered by existing policies may require Operator to purchase additional insurance to comply with applicable regulations, and Operator shall be required to maintain or cause to be maintained such additional insurance. The cost of all flight-specific insurance shall be borne by User as provided in Section 3(d).

9.Use of Aircraft. User warrants that:

(a)He has all necessary powers to enter into the transactions contemplated in this Agreement and has taken actions required to authorize and approve this Agreement;

(b)He will use the Aircraft under this Agreement for and only for his own account, including the carriage of his guests, and will not use the Aircraft for the purpose of providing transportation of passengers or cargo for compensation or hire or for common carriage;

(c)He will not permit as guests on the Aircraft any appointed or elected government official, or any candidates for any such offices.

(d)He will not permit any lien, security interest or other charge or encumbrance to attach against the Aircraft as a result of his actions or inactions, and shall not attempt to convey, mortgage, assign, lease or in any way alienate the Aircraft or Operator’s rights hereunder or create any kind of lien or security interest involving the Aircraft or do anything or take any action that might mature into such a lien;

(e)During the Term of this Agreement, he will abide by and conform to all such laws, governmental and airport orders, rules, and regulations as shall from time to time be in effect relating in any way to the operation or use of the Aircraft by the lessee under a time sharing arrangement and all applicable policies of Operator; and

(f)User acknowledges that his discretion in determining the origin and destination of flights under this Agreement shall be subject to the following: (i) such origin and destination, and the routes to reach such origin and destination, are not within or over (A) an area of hostilities, (B) an area excluded from coverage under the insurance policies maintained by Operator with respect to the Aircraft, or (C) a country or jurisdiction for which exports or transactions are subject to specific restrictions under any United States export or other law or United Nations Security Council Directive, including without limitation, the Trading with the Enemy Act, 50 U.S.C. App. Section 1 et seq., the International Emergency Economic Powers Act, 50 U.S.C. App. Section 1700 et seq., and the Export Administration Act, 50 U.S.C. App. Sections 2401 et seq.
