or her resignation from the Board and any committee of the Board on which he or she then sits; provided, however that if, and so long as, the Board Representation Period remains in effect during such time for either the Icahn Group or
the Other Shareholder (either the Icahn Group or the Other Shareholder, as applicable, the “Continuing Shareholder”) and such group beneficially owns at least (x) 8,039,893 shares of Common Stock or
(y) 10% of then-outstanding shares of Common Stock (in each case, as adjusted from time to time for any stock split or reverse stock or reduced for any buyback in which the Company buys shares in the open market or in a tender offer on a basis

given notice and the opportunity to object by the Company prior to any such adjustment or proposed adjustment) (whichever is less, such number, the “10% Threshold”), then the Icahn Group or the
Other Shareholder, as applicable, shall be entitled to designate an Acceptable Person as a Replacement to replace the Mutual Designee. If the Continuing Shareholder does not beneficially own a number of shares of Common Stock constituting at least
the 10% Threshold, then the Continuing Shareholder shall cease to have any rights related to the designation or nomination of the Mutual Designee under this Agreement. In furtherance of this Section 1(f), the Mutual Designee

nominee in the Company’s proxy statement for such annual meeting until the date that is the first business day following such Annual Meeting.

a member of the Board due to circumstances in which the Icahn Group would be entitled to designate a Replacement pursuant to Section 1(c)(iii), an Icahn Nominee shall be deemed to continue to be a member of the Board for all
purposes of this Agreement until such time as the Icahn Group irrevocably waives in writing any right to designate such a Replacement or designates such a Replacement) (the later of the foregoing periods, the “Board Representation

shares then used in the definition of Acquiring Person (as defined in the Rights Agreement, as amended from time to time, dated as of June 19, 2012, between the Company and Computershare Inc., successor-in-interest to Computershare Shareowner
Services LLC, as Rights Agent (the “Rights Agreement”)) or a similar provision in any New Rights Plan (as hereinafter defined) (clause (x) or (y), as applicable, the “Ownership Limit”); provided,
however, if the Rights Agreement is terminated, eliminated, expires or is otherwise no longer in effect, then this Section 2(c)(A) shall be of no further force and effect and no Ownership Limit shall apply to the Icahn Group or

right or option is exercisable immediately or only after the passage of time or upon the satisfaction of one or more conditions (whether or not within the control of such person), compliance with regulatory requirements or otherwise) and
(iii) any other economic exposure to Voting Securities, including, without limitation, through any derivative transaction that gives any such person or any of such person’s controlled Affiliates the economic equivalent of ownership of an
amount of Voting Securities due to the fact that the value of the derivative is explicitly determined by reference to the price or value of Voting Securities, or which provides such person or any of such person’s controlled Affiliates an
opportunity, directly or indirectly, to profit, or to share in any profit, derived from any change in the value of Voting Securities, in any case without regard to whether (x) such derivative conveys any voting rights in Voting Securities to
such person or any of such person’s controlled Affiliates, (y) the derivative is required to be, or capable of being, settled through delivery of Voting Securities, or (z) such person or any of such person’s controlled Affiliates
may have entered into other transactions that hedge the economic effect of such Beneficial Ownership of Voting Securities. For purposes of this Section 2(c), no Person shall be, or be deemed to be, the “Beneficial
Owner” of, or to “beneficially own,” any securities beneficially owned by any director of the Company to the extent such securities were acquired directly from the Company by such director as or pursuant to director compensation for
serving as a director of the Company and no person shall be deemed to have Beneficial Ownership of any securities owned by a Permitted Person as defined in the Rights Agreement (or New Rights Plan) solely as a result of engaging in any Permitted
Activity with such Permitted Person.

(a) (i) waives, as of the date hereof, any right available to the Company under the Rights Agreement that could allow the Company to
assert or declare that the Icahn Group is, or at any time prior to the date hereof became, an Acquiring Person (as defined in the Rights Agreement), and (ii) agrees, as of the date hereof, not to assert, declare or claim in any manner
whatsoever, that the Icahn Group is, or previously became, an Acquiring Person, in each case, based on, relating to, or concerning, any event, action, conduct, discussion or communication that has occurred prior to the date hereof;

 (b) (i) agrees that entering into this Agreement or exercising any rights under Section 1(a)(ii) or
1(c)(iii) of this Agreement shall not result in the Icahn Group having previously become, or becoming, an Acquiring Person (as defined in the Rights Agreement or any provision having a similar effect under any New Rights Plan (as
defined below)), and (ii) waives, as of the date hereof and at such later time, any right available to the Company under the Rights Agreement that could allow the Company to assert or declare that any matter referred to in clause (b)(i)
resulted in the Icahn Group having previously become, or becoming, an Acquiring Person; 
 (c) agrees that the agreements and
waivers set forth in clauses (a) and (b) above by the Company shall constitute a determination and interpretation by the Board pursuant to Section 29 of the Rights Agreement for the purpose of administering the Rights Agreement;

 (d) within four (4) business days following the date hereof, agrees to file with the SEC a fully executed copy of
Amendment No. 5 (“Amendment No. 5”) to the Rights Agreement in substantially the form attached hereto as Exhibit E and dated and effective as of the date hereof, which form of amendment has been approved by the
Board on or prior to the date hereof; and 
 (e) so long as an Icahn Nominee is a member of the Board, and except for Amendment
No. 5, agrees not to (i) amend, modify, supplement or replace the Rights Agreement, except for any amendment, modification or supplement the sole purpose of which is to extend the expiration date of the Rights Agreement, or (ii) adopt
a New Rights Plan, that, in each case, would be inconsistent with, or restrict the rights, powers, or privileges created by this Section 5 (including but not limited to the Rights Agreement) unless such
amendment, modification, supplement, replacement or New Rights Plan is approved by a majority of the Board, which majority shall include (x) at least one Icahn Nominee and (y) provided that an Other Shareholder Nominee is a member of the
Board, at least one Other Shareholder Nominee. For purposes of this Agreement, a “New Rights Plan” shall mean any plan or arrangement (including any related rights agreement) of the sort commonly referred to as a “rights plan” or
“stockholder rights plan” or “shareholder rights plan” or “poison pill” that is designed to prevent or make more difficult a hostile takeover of the corporation by increasing the cost to a potential acquirer in such a
takeover either through the issuance of new rights, shares of common stock or preferred stock or 

  
 –10–

 
any other security or device that may be issued to stockholders of the corporation other than ratably to all stockholders of the corporation that carry severe redemption provisions, favorable
purchase provisions or otherwise, and any related rights agreement. 
 6. Letter Agreement with Respect to DGCL Section
203. Simultaneously with their entry into this Amendment, the parties hereto agree to enter into a letter agreement substantially in the form of Exhibit F hereto with respect to certain matters relating to Section 203 of the Delaware
General Corporation Law. 
 7. Other Shareholder Agreement. From and after the date hereof, so long as an Icahn Nominee
is a member of the Board, the Company agrees that if it amends, modifies or waives the Other Shareholder Agreement or grants any rights, or otherwise enters into any arrangement, agreement or understanding with the Other Shareholder relating to the
types of matters contemplated by this Agreement or any exhibits hereto that provide any right more favorable than those set forth in this Agreement, that the Company shall offer the same rights to the Icahn Group. 

8. Representations and Warranties of All Parties. Each of the parties represents and warrants to the other party that: 

(a) Such party has all requisite company power and authority to execute and deliver this Amendment and to perform its obligations
hereunder; 
 (b) This Amendment has been duly and validly authorized, executed and delivered by it and is a valid and binding
obligation of such party, enforceable against such party in accordance with its terms; and 
 (c) This Amendment will not result
in a violation of any terms or conditions of any agreements to which such person is a party or by which such party may otherwise be bound or of any law, rule, license, regulation, judgment, order or decree governing or affecting such party.

 9. Representations and Warranties of Icahn Group. Each member of the Icahn Group jointly represents and warrants that,
as of the date of this Amendment, (i) they collectively Beneficially Own, an aggregate of 11,845,167 shares of Common Stock and (ii) except for such ownership, no member of the Icahn Group, individually or
in the aggregate with all other members of the Icahn Group and Icahn Affiliates, has any other Beneficial Ownership of, and/or economic exposure to, any Voting Securities, including, without limitation, through any derivative transaction described
in the definition of “Beneficial Ownership” above. 
 10. Board Resolution. The Company hereby represents and
warrants that the Board has adopted the resolutions in the form attached as Exhibit G. 
 11. Miscellaneous. The
parties hereto recognize and agree that if for any reason any of the provisions of this Agreement are not performed in accordance with their specific terms or are otherwise breached, immediate and irreparable harm or injury would be caused for which
money damages would not be an adequate remedy. Accordingly, each party agrees that in addition to other remedies the other party shall be entitled to at law or equity, the other party shall be entitled to an injunction or injunctions to prevent
breaches of this Agreement 

  
 –11–

 
and to enforce specifically the terms and provisions of this Agreement exclusively in the Court of Chancery or other federal or state courts of the State of Delaware. In the event that any action
shall be brought in equity to enforce the provisions of this Agreement, no party shall allege, and each party hereby waives the defense, that there is an adequate remedy at law. Furthermore, each of the parties hereto (a) consents to submit
itself to the personal jurisdiction of the Court of Chancery or other federal or state courts of the State of Delaware in the event any dispute arises out of this Agreement or the transactions contemplated by this Agreement, (b) agrees that it
shall not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court, (c) agrees that it shall not bring any action relating to this Agreement or the transactions contemplated by this Agreement
in any court other than the Court of Chancery or other federal or state courts of the State of Delaware, and each of the parties irrevocably waives the right to trial by jury, (d) agrees to waive any bonding requirement under any applicable
law, in the case any other party seeks to enforce the terms by way of equitable relief and (e) irrevocably consents to service of process by a reputable overnight mail delivery service, signature requested, to the address of such party’s
principal place of business or as otherwise provided by applicable law. THIS AGREEMENT SHALL BE GOVERNED IN ALL RESPECTS, INCLUDING WITHOUT LIMITATION VALIDITY, INTERPRETATION AND EFFECT, BY THE LAWS OF THE STATE OF DELAWARE APPLICABLE TO CONTRACTS
EXECUTED AND TO BE PERFORMED WHOLLY WITHIN SUCH STATE WITHOUT GIVING EFFECT TO THE CHOICE OF LAW PRINCIPLES OF SUCH STATE. 

12. No Waiver. Any waiver by any party of a breach of any provision of this Agreement shall not operate as or be construed to be a
waiver of any other breach of such provision or of any breach of any other provision of this Agreement. The failure of a party to insist upon strict adherence to any term of this Agreement on one or more occasions shall not be considered a waiver or
deprive that party of the right thereafter to insist upon strict adherence to that term or any other term of this Agreement. 

13. Entire Agreement. The Agreement, as amended and restated in its entirety by this Amendment, and the Confidentiality Agreement
contain the entire understanding of the parties with respect to the subject matter hereof and may be amended only by an agreement in writing executed by the parties hereto. 
 14. Notices. All notices, consents, requests, instructions, approvals and other communications provided for herein and all legal process in regard hereto shall be in writing and shall be deemed

 [FORM OF CONFIDENTIALITY AGREEMENT] 
 NAVISTAR INTERNATIONAL CORPORATION

 [            ], 201[    ] 

To: [Each of the persons or entities listed on Schedule A hereto (the “Icahn Group”)] 

Ladies and Gentlemen: 
 This
letter agreement shall become effective upon the appointment of any Icahn Nominee to the Board of Directors (the “Board”) of Navistar International Corporation (the “Company”) at which time the parties shall execute
the signature page hereto. Capitalized terms used but not otherwise defined herein shall have the meanings given to such terms in the Settlement Agreement (the “Settlement Agreement”), effective as of October 5, 2012, among the
Company and the Icahn Group, as amended and restated in its entirety by Amendment No. 1, effective as of July [•], 2013. The Company understands and agrees that, subject to the terms of, and in accordance with, this letter agreement, the
Icahn Nominee may, if and to the extent he or she desires to do so (in his or her sole and absolute discretion), disclose information he or she obtains while a member of the Board to you and your Representatives (as hereinafter defined) and to any
Designating Person that has executed a confidentiality agreement with the Company and its attorneys, directors, officers and employees subject to such confidentiality agreement, and may discuss such information with any and all such persons. As a
result, you may receive certain non-public information regarding the Company. You acknowledge that this information is proprietary to the Company and may include trade secrets or other business information the disclosure of which could harm the
Company. In consideration for, and as a condition of, the information being furnished to you and, subject to the restrictions in paragraph 2, your attorneys, directors, officers and employees (collectively, the
“Representatives”), you agree to treat any and all information concerning the Company or any of its subsidiaries or affiliates that is furnished to you or your Representatives (regardless of the manner in which it is furnished,
including without limitation in written or electronic format or orally, gathered by visual inspection or otherwise) by any Icahn Nominee, or by or on behalf of the Company, together with any notes, analyses, reports, models, compilations, studies,
interpretations, documents, records or extracts thereof containing, referring, relating to, based upon or derived from such information, in whole or in part (collectively, “Evaluation Material”), in accordance with the provisions of
this letter agreement, and to take or abstain from taking the other actions hereinafter set forth. The term “Designating Person” shall mean any Person that has entered into an agreement with the Company pursuant to which such person
has the right to designate one or more members of the Board and a designee of such Person is serving as a member of the Board at such time. 
 1. The term “Evaluation Material” does not include information that (i) is or has become generally available to the public other than as a result of a direct or indirect disclosure by you
or your Representatives in violation of this letter agreement or any obligation of confidentiality, (ii) was within your or any of your Representatives’ possession on a non-confidential basis prior to its being furnished to you by any
Icahn Nominee, or by or on behalf of the Company or its agents, representatives, attorneys, advisors, directors, officers or employees 

 
(collectively, the “Company Representatives”) or (iii) is received from a source other than any Icahn Nominee, the Company or any of the Company Representatives;
provided, that in the case of (ii) or (iii) above, the source of such information was not believed to you, after reasonable inquiry of the disclosing person, to be bound by a confidentiality agreement with or other contractual,
legal or fiduciary obligation of confidentiality to the Company or any other person with respect to such information at the time the same was disclosed. 
 2. You and your Representatives will, and you will cause your Representatives to, (a) keep the Evaluation Material strictly confidential and (b) not disclose any of the Evaluation Material in
any manner whatsoever without the prior written consent of the Company; provided, however, that you may disclose any of such information: (A) to your Representatives (i) who need to know such information for the sole purpose
of advising you and (ii) who are informed by you of the confidential nature of such information; provided, further, that you will be responsible for any violation of this letter agreement by your Representatives as if they were
parties hereto, except that you will not be so responsible with respect to any such Representative who has executed a copy of this letter agreement as an Additional Signatory and delivered such signed copy to the Company or (B) to any
Designating Person who has executed a copy of a confidentiality agreement with the Company and its attorneys, directors, officers and employees subject to such confidentiality agreement. It is understood and agreed that no Icahn Nominee shall
disclose to you or your Representatives any Legal Advice (as defined below) that may be included in the Evaluation Material with respect to which such disclosure would constitute waiver of the Company’s attorney client privilege or attorney
work product privilege; provided, however, that an Icahn Nominee may provide such disclosure if such Icahn Nominee shall not have taken any action, or failed to take any action, that has the purpose or effect of waiving attorney-client
privilege or attorney work product privilege with respect to any portion of such Legal Advice and if reputable outside legal counsel of national standing provides the Company with a written opinion that such disclosure will not waive the
Company’s attorney client privilege or attorney work product privilege with respect to such Legal Advice. “Legal Advice” as used herein shall be solely and exclusively limited to the advice provided by legal counsel and shall not
include factual information or the formulation or analysis of business strategy. 
 3. In the event that you or any of your
Representatives are required by applicable subpoena, legal process or other legal requirement to disclose any of the Evaluation Material, you will promptly notify (except where such notice would be legally prohibited) the Company in writing by
facsimile and certified mail so that the Company may seek a protective order or other appropriate remedy (and if the Company seeks such an order, you will provide such cooperation as the Company shall reasonably request), at its cost and expense.
Nothing herein shall be deemed to prevent you or your Representatives, as the case may be, from honoring a subpoena, legal process or other legal requirement that requires discovery, disclosure or production of the Evaluation Material if
(a) you produce or disclose only that portion of the Evaluation Material which your outside legal counsel of national standing advises you is legally required to be so produced or disclosed and you inform the recipient of such Evaluation
Material of the existence of this letter agreement and the confidential nature of such Evaluation Material; or (b) the Company consents in writing to having the Evaluation Material produced or disclosed pursuant to the subpoena, legal process
or other legal requirement. In no event will you or any of your Representatives oppose action by the Company to obtain a protective order or other relief to prevent the disclosure of the Evaluation Material or to obtain reliable assurance that
confidential 

 
treatment will be afforded the Evaluation Material. It is understood that there shall be no “legal requirement” requiring you to disclose any Evaluation Material solely by virtue of the
fact that, absent such disclosure, you would be prohibited from purchasing, selling, or engaging in derivative or other transactions with respect to, the Common Stock of the Company or otherwise proposing or making an offer to do any of the
foregoing or making any offer, including any tender offer, or you would be unable to file any proxy materials in compliance with Section 14(a) of the Exchange Act or the rules promulgated thereunder. 

4. You acknowledge that (a) none of the Company or any of the Company Representatives makes any representation or warranty, express
or implied, as to the accuracy or completeness of any Evaluation Material, and (b) none of the Company or any of the Company Representatives shall have any liability to you or to any of your Representatives relating to or resulting from the use
of the Evaluation Material or any errors therein or omissions therefrom. You and your Representatives shall not directly or indirectly initiate contact or communication with any executive or employee of the Company other than the Chief Executive
Officer, Chief Financial Officer and Chief Operating Officer concerning Evaluation Material, or to seek any information in connection therewith from any such person other than the Chief Executive Officer, Chief Financial Officer and Chief Operating
Officer, without the prior consent of the Company; provided, however, the restriction in this sentence shall not in any way apply to any Icahn Nominee or other Board members. 
 5. All Evaluation Material shall remain the property of the Company. Neither you nor any of your Representatives shall by virtue of any disclosure of and/or your use of any Evaluation Material acquire any
rights with respect thereto, all of which rights (including all intellectual property rights) shall remain exclusively with the Company. At any time after the date on which no Icahn Nominee is a director of the Company, upon the request of the
Company for any reason, you will promptly return to the Company all hard copies of the Evaluation Material and use commercially reasonable efforts to permanently erase or delete all electronic copies of the Evaluation Material in your or any of your
Representatives’ possession or control (and, upon the request of the Company, shall certify to the Company that such Evaluation Material has been erased or deleted, as the case may be). Notwithstanding the return or erasure or deletion of
Evaluation Material, you and your Representatives will continue to be bound by the obligations contained herein. 
 6. You
acknowledge, and will advise your Representatives, that the Evaluation Material may constitute material non-public information under applicable federal and state securities laws, and that you shall not, and you shall use your commercially reasonable
efforts to ensure that your Representatives, do not, trade or engage in any derivative or other transaction, on the basis of such information in violation of such laws. 
 7. You hereby represent and warrant to the Company that (i) you have all requisite company power and authority to execute and deliver this letter agreement and to perform your obligations hereunder,
(ii) this letter agreement has been duly authorized, executed and delivered by you, and is a valid and binding obligation, enforceable against you in accordance with its terms, (iii) this Agreement will not result in a violation of any
terms or conditions of any agreements to which you are a party or by which you may otherwise be bound or of any law, rule, license, regulation, judgment, order or decree governing or affecting you, and (iv) your entry into this Agreement does
not require approval by any owners or holders of any equity interest in you (except as has already been obtained). 

 8. Any waiver by the Company of a breach of any provision of this letter agreement shall not
operate as or be construed to be a waiver of any other breach of such provision or of any breach of any other provision of this letter agreement. The failure of the Company to insist upon strict adherence to any term of this letter agreement on one
or more occasions shall not be considered a waiver or deprive the Company of the right thereafter to insist upon strict adherence to that term or any other term of this letter agreement. 

9. You acknowledge and agree that the value of the Evaluation Material to the Company is unique and substantial, but may be impractical
or difficult to assess in monetary terms. You further acknowledge and agree that in the event of an actual or threatened violation of this letter agreement, immediate and irreparable harm or injury would be caused for which money damages would not
be an adequate remedy. Accordingly, you acknowledge and agree that, in addition to any and all other remedies which may be available to the Company at law or equity, the Company shall be entitled to an injunction or injunctions to prevent breaches
of this letter agreement and to enforce specifically the terms and provisions of this letter agreement exclusively in the Court of Chancery or other federal or state courts of the State of Delaware. In the event that any action shall be brought in
equity to enforce the provisions of this letter agreement, you shall not allege, and you hereby waive the defense, that there is an adequate remedy at law. 
 10. Each of the parties hereto (a) consents to submit itself to the personal jurisdiction of the Court of Chancery or other federal or state courts of the State of Delaware in the event any dispute
arises out of this letter agreement or the transactions contemplated by this letter agreement, (b) agrees that it shall not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court,
(c) agrees that it shall not bring any action relating to this letter agreement or the transactions contemplated by this letter agreement in any court other than the Court of Chancery or other federal or state courts of the State of Delaware,
and each of the parties irrevocably waives the right to trial by jury, (d) agrees to waive any bonding requirement under any applicable law, in the case any other party seeks to enforce the terms by way of equitable relief, and
(e) irrevocably consents to service of process by a reputable overnight delivery service, signature requested, to the address of such party’s principal place of business or as otherwise provided by applicable law. THIS LETTER AGREEMENT
SHALL BE GOVERNED IN ALL RESPECTS, INCLUDING WITHOUT LIMITATION VALIDITY, INTERPRETATION AND EFFECT, BY THE LAWS OF THE STATE OF DELAWARE APPLICABLE TO CONTRACTS EXECUTED AND TO BE PERFORMED WHOLLY WITHIN SUCH STATE WITHOUT GIVING EFFECT TO THE
CHOICE OF LAW PRINCIPLES OF SUCH STATE. 
 11. This letter agreement and the Amendment contain the entire understanding of the
parties with respect to the subject matter hereof and thereof and this letter agreement may be amended only by an agreement in writing executed by the parties hereto. 

 12. All notices, consents, requests, instructions, approvals and other communications
provided for herein and all legal process in regard hereto shall be in writing and shall be deemed validly given, made or served, if (a) given by telecopy and email, when such telecopy is transmitted to the telecopy number set forth below and

Subsidiary of the Company, or any Person or entity organized, appointed or established by the Company for or pursuant to the terms of any such plan) unless and until such Person, after becoming aware that such Person has become the Beneficial Owner

Beneficial Owner of a higher percentage of the shares of Common Stock then outstanding (other than as a result of a reduction in the number of shares of Common Stock outstanding due to the repurchase of Common Stock by the Company (or any Subsidiary
of the Company, any employee benefit plan of the Company or any Subsidiary of the Company, or any Person or entity organized, appointed or established by the Company for or pursuant to the terms of any such plan)) as compared to the percentage of

 Exhibit A 
 FORM OF 
 SUMMARY OF RIGHTS TO PURCHASE 

PREFERRED STOCK 

On June 19, 2012, the Board of Directors (the “Board”) of Navistar International Corporation, a Delaware corporation (the
“Company”), authorized and declared a dividend distribution of one right (a “Right”) for each outstanding share of the common stock of the Company, par value $0.10 per share (the “Common Stock”), to stockholders of
record at the close of business on June 29, 2012 (the “Record Date”). Each Right entitles the registered holder to purchase from the Company a unit consisting of one one-thousandth of a share (a “Unit”) of a newly authorized
series of Junior Participating Preferred Stock, Series A, par value $1.00 per share (the “Preferred Stock”), at a purchase price of $140.00 per Unit, subject to adjustment (the “Purchase Price”). The complete terms of the Rights
are set forth in a Rights Agreement, dated as of June 19, 2012, as amended to date, between the Company and Computershare Inc., successor-in-interest to Computershare Shareowner Services LLC, as Rights Agent (the “Rights Agreement”).

 Rights Certificates; Exercise Period. 
 Initially, the Rights will be attached to all shares of Common Stock then outstanding, and no separate rights certificates (“Rights Certificates”) will be distributed. Subject to certain
exceptions specified in the Rights Agreement, the Rights will separate from the Common Stock and a distribution date (a “Distribution Date”) will occur upon the earlier of (i) 10 business days following a public announcement that a
person or group of affiliated or associated persons (an “Acquiring Person”) has acquired beneficial ownership of twenty percent (20%) or more of the outstanding shares of Common Stock (the “Stock Acquisition Date”), other
than as a result of repurchases of stock by the Company or certain inadvertent actions by certain stockholders or (ii) 10 business days (or such later date as the Board shall determine) following the commencement of a tender offer or exchange
offer that would result in a person or group becoming an Acquiring Person. For purposes of the Rights Agreement, beneficial ownership is defined to include ownership of derivative securities. 

Until a Distribution Date, (i) the Rights will be evidenced by the certificates for the Common Stock (or, in the case of shares
reflected on the direct registration system, by the notations in the book-entry account system) and will only be transferable with such Common Stock, (ii) new Common Stock certificates issued after the Record Date will contain a legend
incorporating the Rights Agreement by reference and (iii) the surrender for transfer of any certificates for Common Stock outstanding will also constitute the transfer of the Rights associated with the Common Stock represented by such
certificates. Pursuant to the Rights Agreement, the Company reserves the right to require prior to the occurrence of a Triggering Event (as defined below) that, upon any exercise of Rights, a number of Rights be exercised so that only whole shares
of Preferred Stock will be issued. 
 The Rights are not exercisable until a Distribution Date and will expire at 5:00 P.M., New
York City time on June 18, 2015, unless such date is extended or the Rights are earlier redeemed, exchanged or terminated. 

 As soon as practicable after a Distribution Date, Rights Certificates will be mailed to
holders of record of the Common Stock as of the close of business on a Distribution Date and, thereafter, the separate Rights Certificates alone will represent the Rights. Except as otherwise determined by the Board, only shares of Common Stock
issued prior to a Distribution Date will be issued with Rights. 
 Flip-in Trigger. 

In the event that a person or group of affiliated or associated persons becomes an Acquiring Person, except pursuant to an offer for all
outstanding shares of Common Stock which the independent directors determine to be fair and not inadequate and to otherwise be in the best interests of the Company and its stockholders after receiving advice from one or more investment banking
firms, each holder of a Right will thereafter have the right to receive, upon exercise, Common Stock (or, in certain circumstances, cash, property or other securities of the Company) having a value equal to two times the exercise price of the Right.
Notwithstanding the foregoing, following the occurrence of the event set forth in this paragraph, all Rights that are, or (under certain circumstances specified in the Rights Agreement) were, beneficially owned by any Acquiring Person will be null
and void. However, Rights are not exercisable following the occurrence of the event set forth above until such time as the Rights are no longer redeemable by the Company as set forth below. Any person who, together with its affiliates and
associates, beneficially owns 20% or more of the outstanding shares of Common Stock as of the time of first public announcement of the Rights Agreement (an “Exempt Person”) shall not be deemed an Acquiring Person, but only for so long as
such person, together with its affiliates and associates, does not, while such person is an Exempt Person, become the Beneficial Owner of a higher percentage of the shares of Common Stock then outstanding (other than as a result of a reduction in
the number of shares of Common Stock outstanding due to the repurchase of Common Stock by the Company (or any Subsidiary of the Company, any employee benefit plan of the Company or any Subsidiary of the Company, or any Person or entity organized,
appointed or established by the Company for or pursuant to the terms of any such plan)) as compared to the percentage of shares of Common Stock outstanding Beneficially Owned by such Exempt Person as of the Exempt Time. 

Flip-over Trigger. 
 In the event that, at any time following the Stock Acquisition Date, (i) the Company engages in a merger or other business combination transaction in which the Company is not the surviving
corporation, (ii) the Company engages in a merger or other business combination transaction in which the Company is the surviving corporation and the Common Stock of the Company is changed or exchanged, or (iii) 50% or more of the
Company’s assets, cash flow or earning power is sold or transferred, each holder of a Right (except Rights which have previously been voided as set forth above) shall thereafter have the right to receive, upon exercise, common stock of the
acquiring company having a value equal to two times the exercise price of the Right. The events set forth in this paragraph and in the preceding paragraph are referred to as the “Triggering Events.” 

  
 2 

 Exchange Feature. 

At any time after a person becomes an Acquiring Person and prior to the acquisition by such person or group of fifty percent (50%) or
more of the outstanding Common Stock, the Board may exchange the Rights (other than Rights owned by such person or group which have become null and void), in whole or in part, at an exchange ratio of one share of Common Stock, or one one-thousandth
of a share of Preferred Stock (or of a share of a class or series of the Company’s preferred stock having equivalent rights, preferences and privileges), per Right (subject to adjustment). 

Equitable Adjustments. 
 The Purchase Price payable, and the number of Units of Preferred Stock or other securities or property issuable, upon exercise of the Rights are subject to adjustment from time to time to prevent dilution
(i) in the event of a dividend on the Preferred Stock payable in shares of Preferred Stock, a subdivision or split of outstanding shares of Preferred Stock, a combination or consolidation of Preferred Stock into a smaller number of shares
through a reverse stock split or otherwise, or reclassification of the Preferred Stock, (ii) if holders of the Preferred Stock are granted certain rights, options or warrants to subscribe for Preferred Stock or convertible securities at less
than the current market price of the Preferred Stock, or (iii) upon the distribution to holders of the Preferred Stock of cash (excluding regular quarterly cash dividends), assets, evidences of indebtedness or of subscription rights or warrants
(other than those referred to above). 
 With certain exceptions, no adjustment in the Purchase Price will be required until
cumulative adjustments amount to at least 1% of the Purchase Price. No fractional Units will be issued and, in lieu thereof, an adjustment in cash will be made based on the market price of the Preferred Stock on the last trading date prior to the
date of exercise. 
 Redemption Rights. 
 At any time until ten business days following the Stock Acquisition Date, the Company may redeem the Rights in whole, but not in part, at a price of $0.001 per Right (payable in cash, Common Stock or
other consideration deemed appropriate by the Board). Immediately upon the action of the Board ordering redemption of the Rights, the Rights will terminate and the only right of the holders of Rights will be to receive the $0.001 redemption price.

 Miscellaneous. 
 Until a Right is exercised, the holder thereof, as such, will have no separate rights as a stockholder of the Company, including, without limitation, the right to vote or to receive dividends in respect
of Rights. While the distribution of the Rights will not be taxable to stockholders or to the Company, stockholders may, depending upon the circumstances, recognize taxable income in the event that the Rights become exercisable for Common Stock (or
other consideration) of the Company or for common stock of the acquiring company or in the event of the redemption of the Rights as set forth above. 

  
 3 

 Amendment. 
 Any of the provisions of the Rights Agreement may be amended by the Board prior to a Distribution Date. After a Distribution Date, the provisions of the Rights Agreement may be amended by the Board in
order to cure any ambiguity, to make changes which do not adversely affect the interests of holders of Rights, or to shorten or lengthen any time period under the Rights Agreement. Notwithstanding the foregoing, no amendment may be made (other than
to cure any ambiguity) at a time when the Rights are not redeemable. 
 Anti-Takeover Effects. 

The Rights may have certain anti-takeover effects. The Rights may cause substantial dilution to any person or group that attempts to
acquire the Company without the approval of the Board. As a result, the overall effect of the Rights may be to render more difficult or discourage a merger, tender offer or other business combination involving the Company that is not supported by
the Board. 
 A copy of the Rights Agreement has been filed with the Securities and Exchange Commission as an Exhibit to a
Registration Statement on Form 8-A or a Current Report on Form 8-K. A copy of the Rights Agreement is available free of charge from the Company. This summary description of the Rights does not purport to be complete and is qualified in its entirety
by reference to the Rights Agreement, which is incorporated herein by reference.

 EXHIBIT F 
 AGREEMENT 
 This Agreement (the “Agreement”) is made and
entered into as of July 14, 2013, by and among the persons and entities listed on Schedule A hereto (each, individually, an “Icahn Entity” and collectively, the “Icahn Entities”) and Navistar International
Corporation, a Delaware corporation (the “Company”). 
 WHEREAS, the Icahn Entities and their respective
affiliates and associates may desire to acquire ownership of additional shares of common stock, par value $.01 per share, of the Company (“Common Stock”) without being subject to the restrictions under Section 203 of the
General Corporation Law of the State of Delaware (“DGCL 203”) applicable to a “business combination” with an “interested stockholder” (each such term, as used in this Agreement, shall have the meaning given to it
in DGCL 203, except as described in Section 4 hereof), so long as the Icahn Entities and their affiliates and associates do not own 20% or more of the voting power of the then issued and outstanding shares of voting stock of the Company;

 WHEREAS, as of the date hereof, the Company and the Icahn Entities have no current discussions or negotiations with each
other regarding a business combination or other extraordinary transaction involving the Company; 
 NOW THEREFORE, in
consideration of the premises and the covenants of the parties set forth in this agreement, and for other good and valuable consideration the receipt and adequacy of which are hereby acknowledged, and intending to be legally bound, the undersigned
hereby agree as follows: 
 1. The Company hereby represents and warrants to the Icahn Entities that the Board of Directors of
the Company has duly approved (the “Board Approval”) this Agreement and the acquisition by the Icahn Entities and their respective affiliates and associates, whether in a single transaction or multiple transactions from time to
time, of additional shares of Common Stock to the extent such acquisitions would result in the Icahn Entities and their affiliates and associates being the owner of 15% or more, but less than 20%, of the voting power of the shares of voting stock of
the Company issued and outstanding from time to time, subject to the limitations provided for in Section 4 hereof and subject to the accuracy of the representations and warranties set forth in Section 2 hereof. 

2. The Icahn Entities hereby represent and warrant that, as of the date of this Agreement and assuming the accuracy of the
representations and warranties set forth in Section 3 hereof, the Icahn Entities and their affiliates and associates are, in the aggregate, owners of less than 15% of the shares of Common Stock issued and outstanding as of the date of this
Agreement. 

  
 1 

 3. The Company hereby represents and warrants that, as of the date of this Agreement, there
are              shares of Common Stock issued and outstanding which is the only class of “voting stock” (as defined herein) of the Company. 

4. Each of the Icahn Entities agrees that if any Icahn Entity or any of its affiliates and associates becomes the owner of shares of
voting stock of the Company such that the Icahn Entities would, together with their affiliates and associates, in the aggregate own 20% or more of the voting power of the issued and outstanding shares of voting stock of the Company under
circumstances in which they would be an “interested stockholder” as defined in DGCL 203 (but, for this purpose, replacing 15% in such definition with 20%) (any event causing the Icahn Entities and their affiliates and associates to own in
the aggregate 20% or more of the voting power of the then issued and outstanding shares of voting stock of the Company, an “Additional Acquisition”), then (i) notwithstanding the Board Approval referred to in Section 1 of this
Agreement, the restrictions under DGCL 203 applicable to a “business combination” with an “interested stockholder” shall apply as a matter of contract pursuant to this Agreement (except as modified herein) to the Icahn Entities
and their respective affiliates and associates as if such Board Approval had not been granted and as if the Additional Acquisition had caused each Icahn Entity and its affiliates and associates to become an interested stockholder for purposes of
DGCL 203, except that wherever 15% is used in DGCL 203 it shall mean, for all purposes of this Agreement, 20%; and (ii) the Icahn Entities and their affiliates and associates will not engage in any business combination with the Company for a
period of 3 years following the time that the Icahn Entities and their affiliates and associates became an owner of 20% or more of the voting power of the then issued and outstanding shares of voting stock of the Company, unless: 

(1) prior to such time the Board of Directors of the Company approved, including approval by a majority of the Non- Icahn Directors (as
defined in Section 5), either the business combination or the Additional Acquisition; 
 (2) upon consummation of the
transaction which resulted in the Icahn Entities and their affiliates and associates becoming an owner of 20% or more of the voting power of the issued and outstanding shares of voting stock of the Company, the Icahn Entities and their affiliates
and associates owned at least 85% of the voting power of the voting stock of the Company outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock outstanding (but not the outstanding voting stock
owned by the Icahn Entities and their affiliates and associates) those shares owned (i) by persons who are directors and also officers of the Company and (ii) employee stock plans in which employee participants do not have the right to
determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or 
 (3) at or
subsequent to such time the business combination is approved by the Board of Directors of the Company, including by a majority of the Non- Icahn Directors, and authorized at an annual or special meeting of stockholders, and not by written consent,
by the affirmative vote of at least 66 2/3% of the voting power of the outstanding voting stock which is not owned by the Icahn Entities and their affiliates and associates; 
 provided, that, the restrictions set forth above shall not apply if any of the exceptions in DGCL Section 203(b)(4), (5) or (6) would be applicable at the time of such business combination.

 5. This Agreement may be executed in counterparts, each of which shall be deemed to be an
original, with the same effect as if the signatures were upon the same instrument. All representations, warranties, covenants and agreements made herein shall survive the execution and delivery of this Agreement. This Agreement constitutes the
entire agreement among the parties hereto in respect of the subject matter hereof. No provision of this Agreement may be: (a) amended except by an instrument in writing executed by the parties hereto; or (b) waived except by an instrument
in writing executed by the party against whom the waiver is to be effective; provided that any such amendment or waiver has been approved by the Board of Directors of the Company, including, to the fullest extent permitted by law, by a majority of
the Non- Icahn Directors. This Agreement shall not be terminated except by an instrument in writing executed by the parties hereto; provided that any such termination has been approved by the Board of Directors of the Company, including, to the
fullest extent permitted by law, by a majority of the Non- Icahn Directors. For purposes of this Agreement, “Non- Icahn Directors” shall mean the members of the Board of Directors of the Company that are not affiliated with, and
were not nominated by, any Icahn Entity or any affiliate or associate thereof or any other stockholder of the Company (including any affiliate or associate of any such stockholder) that is subject to an agreement similar to this Agreement. This
Agreement: (i) shall not be assignable by any of the parties hereto; and (ii) shall be binding on successors of the parties hereto. 
 6. This Agreement shall be governed by, and construed and interpreted in accordance with, the laws of the State of Delaware, without regard to choice of law principles that would compel the application of
the laws of any other jurisdiction. Each of the parties hereto irrevocably agrees that any legal action or proceeding that may be based upon, arise out of or relate to this Agreement or the negotiation, execution or performance hereof, shall be
brought and determined exclusively in the Chancery Court of the State of Delaware and any state appellate court therefrom located in the State of Delaware (or, only if the Chancery Court of the State of Delaware declines to accept jurisdiction over
a particular matter, any state or federal court located in the State of Delaware). 
 7. Each of the parties hereto hereby
irrevocably waives any and all rights to trial by jury in any legal proceeding arising out of or related to this Agreement. 

8. The parties hereto agree that irreparable damage, for which monetary damages would not be an adequate remedy, would occur in the event
that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached by the parties hereto. It is accordingly agreed that the parties hereto shall be entitled to an injunction or
injunctions, or any other appropriate form of specific performance or equitable relief, to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of competent jurisdiction, this being in addition
to any other remedy to which they are entitled under the terms of this Agreement at law or in equity. Each party hereto accordingly agrees not to raise any objections to the availability of the equitable remedy of specific performance to prevent or
restrain breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of such party under this Agreement. 
 9. The parties hereto have participated jointly in the negotiation and drafting of this Agreement and, in the event an ambiguity or question of intent or interpretation arises, this Agreement shall be
construed as jointly drafted by the parties hereto and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement.

 10. As used in this Agreement, the terms “affiliate,”
“associate,” “owner,” including the terms “own” and “owned,” “stock” and “voting stock” have the meanings given to them in DGCL 203; provided, that
(a) the Icahn Entities and their affiliates and associates shall not be deemed to be an “owner” of, or to “own” or have “owned,” any stock owned by any “Permitted Person” solely by
virtue of engaging in a “Permitted Activity” with such Permitted Person, as such terms are currently defined in Amendment No. 1 to Rights Agreement, dated as of October 5, 2012, between the Company and Computershare Inc., a
Delaware corporation, successor-in-interest to Computershare Shareowner Services LLC, a New Jersey limited liability company, as rights agent, as in effect on the date hereof, and (b) for the avoidance of doubt, the Company’s
Nonconvertible Junior Preference Stock, Series B, par value $1.00 per share, and the Company’s Convertible Junior Preference Stock, Series D, par value $1.00 per share, each with the rights currently set forth in the Company’s certificate
of incorporation in effect on the date hereof, shall not be deemed to be voting stock for purposes of this Agreement.

any amendments and/or exhibits thereto, contains the same terms and conditions as this Agreement, including the Confidentiality Agreement (as hereinafter defined), but with all references to the MHR Group, the MHR Affiliates and the MHR Nominee

The Company hereby acknowledges and agrees that the MHR Nominee does not have a material relationship with the Company as such term is used in Section 303A.02 of the NYSE Manual by virtue of the MHR Group’s beneficial ownership of shares

Company in writing if he or she will not consent to be named as a nominee in the Company’s proxy statement for such Annual Meeting. Other than in the event described in the proviso of the preceding sentence, the Company agrees to use
commercially reasonable efforts to cause the election of any such nominees so nominated by the Company (including recommending that the Company’s stockholders vote in favor of the election of any such nominees, including such nominees in the
Company’s proxy statement and in the Company’s slate of nominees for directors for such Annual Meeting and otherwise supporting any such nominee for election in a manner no less rigorous and favorable than the manner in which the Company
supports its other nominees in the aggregate); 
 (v) that as of the date of this Amendment, the Company
represents and warrants that the Board is composed of nine (9) directors and that there are no vacancies on the Board. The Company agrees not to increase the size of the Board to greater than nine (9) directors prior to the completion of

Shareholder Nominees at the 2014 Annual Meeting. The Company agrees that, from and after the date of this Amendment, so long as an MHR Nominee is a member of the Board, the Company shall not take any action, or support any person who is seeking, to
increase the size of the Board above ten (10) directors, each having one vote on all matters; and 
 (vi)
not to create an executive committee of the Board without the approval of a majority of the Board, which majority shall include (x) at least one MHR Nominee and (y) provided that an Other Shareholder Nominee is a member of the Board, at
least one Other Shareholder Nominee. 
 (d) If (A) the MHR Group has elected to include no MHR Nominees on the
Company’s slate of nominees for election as directors at any Annual Meeting subsequent to the 2014 Annual Meeting pursuant to Section 1(c)(iv) of this Amendment, (B) the Board Representation Period for the MHR Group
has ended or (C) the Company has breached this Amendment by (x) failing to include in any applicable Company Notice the MHR Nominees named pursuant to any MHR Notice, (y) failing to comply with Section 1(b)(ii) or
(z) failing to nominate any MHR Nominee which the MHR Group is entitled to designate pursuant to Section 1(a) or Section 1(b) of this Amendment and whom the MHR Group has named in any MHR Notice, in addition to any
other remedies to which it may be entitled, the MHR Group shall be free to nominate a slate of nominees for election as directors at such Annual Meeting in accordance with Article I, Section 8 of the Bylaws; provided that, with respect
to clause (C) above, such nomination may be made without regard to the advance notice requirements contained in Article 1, Section 8 of the Bylaws.

 (e) Notwithstanding anything in Section ,1(b), if, at any time after
the date of this Amendment, the MHR Group, together with the MHR Affiliates, collectively beneficially own (i) if two MHR Nominees have been elected to the Board in accordance with Section 1(b), less than
(w) 4,019,946 shares of Common Stock or (x) 5% of then-outstanding shares of Common Stock (in each case, as adjusted from time to time for any stock split or reverse stock or reduced for any buyback in which the Company buys shares
in the open market or in a tender offer on a basis equally available to all stockholders (to the extent that the MHR Group or any MHR Affiliate participates in any such buyback on a pro rata, or less than pro rata, basis); provided that the
MHR Group and the Other Shareholder shall be given notice and the opportunity to object by the Company prior to any such adjustment or proposed adjustment) (whichever is less, such number, the “5% Threshold”) but a
number of shares of Common Stock equal to or greater than (y) 2,009,973 or (z) 2.5% of then-outstanding shares of Common Stock (in each case, as adjusted from time to time for any stock split or reverse stock or
reduced for any buyback in which the Company buys shares in the open market or in a tender offer on a basis equally available to all stockholders (to the extent that the MHR Group or any MHR Affiliate participates in any such buyback on a pro rata,
or less than pro rata, basis); provided that the MHR Group and the Other Shareholder shall be given notice and the opportunity to object by the Company prior to any such adjustment or proposed adjustment) (whichever is less, such
number, the “2.5% Threshold”) as of such date, the MHR Group shall cause one MHR Nominee to promptly tender his or her resignation from the Board and any committee of the Board on which he or she then sits, and
(ii) in all cases, a number of shares of Common Stock constituting less than the 2.5% Threshold as of such date, (1) the MHR Group shall cause each MHR Nominee to promptly tender his or her resignation from the Board and any committee of
the Board on which he or she then sits and (2) the Company shall have no further obligations under this Section 1. In furtherance of this Section 1(e), any MHR Nominee shall, prior to
his or her appointment to the Board, and each member of the MHR Group shall cause each such MHR Nominee to, execute an irrevocable resignation as director in the form attached hereto as Exhibit B and deliver it to the Company. For purposes of
this Agreement: the term “Affiliate” shall have the meaning set forth in Rule 12b-2 promulgated by the SEC under the Exchange Act; and the terms “person” or “persons” shall mean any individual, corporation (including
not-for-profit), general or limited partnership, limited liability or unlimited liability company, joint venture, estate, trust, association, organization or other entity of any kind or nature. 

(f) If, at any time after the date of this Amendment and prior to the 2014 Annual Meeting, the Board Representation Period (as defined in
Section 2(a)) for either the MHR Group or the Other Shareholder (such period with respect to the Other Shareholder as defined in the Other Shareholder Agreement) terminates, then the Mutual Designee shall promptly tender his or
her resignation from the Board and any committee of the Board on which he or she then sits; provided, however that if, and so long as, the Board Representation Period remains in effect during such time for either the MHR Group or the
Other Shareholder (either the MHR Group or the Other Shareholder, as applicable, the “Continuing Shareholder”) and such group beneficially owns at least (x) 8,039,893 shares of Common Stock or (y)
10% of then-outstanding shares of Common Stock (in each case, as adjusted from time to time for any stock split or reverse stock or reduced for any buyback in which the Company buys shares in the open market or in a tender offer on a basis equally
available to all stockholders (to the extent that the MHR Group or any MHR Affiliate participates in any such buyback on a pro rata, or less than pro rata, basis); provided that the MHR Group and the Other Shareholder shall be given notice
and the opportunity to object by the Company prior to any such adjustment or proposed adjustment) (whichever is less, such number, the “10% Threshold”), then the MHR Group or the Other Shareholder,
as applicable, shall be entitled to designate an Acceptable Person as a Replacement to replace the Mutual Designee. If the Continuing Shareholder does not beneficially own a number of shares of Common Stock constituting at least the 10% Threshold,
then the Continuing Shareholder shall cease to have any rights related to the designation or nomination of the Mutual Designee under this Agreement. In furtherance of this Section 1(f), the Mutual Designee shall, prior to his
or her appointment to the Board, execute an irrevocable resignation as director in the form attached hereto as Exhibit C and deliver it to the Company.

Company’s proxy statement for an Annual Meeting, may resign from the Board during the period from the date on which such nominee grants his or her consent to be named as a nominee in the Company’s proxy statement for such annual meeting
until the date that is the first business day following such Annual Meeting.

member of the Board due to circumstances in which the MHR Group would be entitled to designate a Replacement pursuant to Section 1(c)(iii), an MHR Nominee shall be deemed to continue to be a member of the Board for all purposes
of this Agreement until such time as the MHR Group irrevocably waives in writing any right to designate such a Replacement or designates such a Replacement) (the later of the foregoing periods, the “Board Representation Period”),

any person who has served as an officer or director of the Company in the past or (viii) institute, solicit, assist or join, as a party, any litigation, arbitration or other proceeding against or involving the Company or any of its current or
former directors or officers (including derivative actions). As used in this Agreement, the term “Voting Securities” shall mean the common stock, par value $0.10 per share, of the Company (the “Common Stock”) and any other
securities of the Company entitled to vote in the election of directors, or securities convertible into, or exercisable or exchangeable for Common Stock or other securities, whether or not subject to the passage of time or other contingencies. No

Agreement is then in effect. 
 (b) So long as the Company has complied and is complying with its obligations
set forth in this Agreement, during the Board Representation Period, each member of the MHR Group shall (1) cause, in the case of all Voting Securities owned of record, and (2) instruct the record owner, in the case of all shares of Voting

accordance with the recommendation of the Board for the ratification of the appointment of the Company’s independent public accounting firm set forth in the Company’s proxy statement for any such Annual Meeting. 

(c) So long as the Company has complied and is complying with its obligations set forth in this Agreement, during the Board Representation
Period, each member of the MHR Group agrees (and agrees to cause each MHR Affiliate to comply with the provisions of this Section 2(c)) not to (A) acquire (in the aggregate with all other members of the MHR Group and all
MHR Affiliates) Beneficial Ownership of Voting Securities that would exceed the greater of one share of any Voting Securities less than (x) 20.0% of the then total outstanding Voting Securities and (y) the percentage of outstanding shares
then used in the definition of Acquiring Person (as defined in the Rights Agreement, as amended from time to time, dated as of June 19, 2012, between the Company and Computershare Inc., successor-in-interest to Computershare Shareowner Services
LLC, as Rights Agent (the “Rights Agreement”)) or a similar provision in any New Rights Plan (as hereinafter defined) (clause (x) or (y), as applicable, the “Ownership Limit”); provided, however, if the
Rights Agreement is terminated, eliminated, expires or is otherwise no longer in effect, then this Section 2(c)(A) shall be of no further force and effect and no Ownership Limit shall apply to the MHR Group or (B) without
the prior approval of the Board, directly, or in conjunction with any other person or entity in which it is or proposes to be either a principal, partner or financing source or is acting or proposes to act as broker or agent for compensation,
propose (publicly or to the Company) or participate in, any (1) tender offer or exchange offer, merger, acquisition or other business combination involving the Company or any of its subsidiaries or (2) form of business combination or
acquisition or other transaction relating to a material amount of the assets of the Company or any of its subsidiaries. As used in this Agreement, the term “Beneficial Ownership” of “Voting Securities” means ownership of (solely

by virtue of owning an economic interest in or the right to vote or cause to vote): (i) Voting Securities, (ii) rights or options to own or acquire any Voting Securities (whether such
right or option is exercisable immediately or only after the passage of time or upon the satisfaction of one or more conditions (whether or not within the control of such person), compliance with regulatory requirements or otherwise) and
(iii) any other economic exposure to Voting Securities, including, without limitation, through any derivative transaction that gives any such person or any of such person’s controlled Affiliates the economic equivalent of ownership of an
amount of Voting Securities due to the fact that the value of the derivative is explicitly determined by reference to the price or value of Voting Securities, or which provides such person or any of such person’s controlled Affiliates an
opportunity, directly or indirectly, to profit, or to share in any profit, derived from any change in the value of Voting Securities, in any case without regard to whether (x) such derivative conveys any voting rights in Voting Securities to
such person or any of such person’s controlled Affiliates, (y) the derivative is required to be, or capable of being, settled through delivery of Voting Securities, or (z) such person or any of such person’s controlled Affiliates
may have entered into other transactions that hedge the economic effect of such Beneficial Ownership of Voting Securities. For purposes of this Section 2(c), no Person shall be, or be deemed to be, the “Beneficial
Owner” of, or to “beneficially own,” any securities beneficially owned by any director of the Company to the extent such securities were acquired directly from the Company by such director as or pursuant to director compensation for
serving as a director of the Company and no person shall be deemed to have Beneficial Ownership of any securities owned by a Permitted Person as defined in the Rights Agreement (or New Rights Plan) solely as a result of engaging in any Permitted
Activity with such Permitted Person. 
 (d) Each member of the MHR Group hereby releases the Company and its subsidiaries, and
each and all of their respective past or present directors, officers, stockholders, employees, advisors, attorneys, agents, predecessors, successors and assigns, from any and all claims of any kind whatsoever, whether known or unknown, accrued or

 5. Rights Agreement. The Company hereby:

assert or declare that the MHR Group is, or at any time prior to the date hereof became, an Acquiring Person (as defined in the Rights Agreement), and (ii) agrees, as of the date hereof, not to assert, declare or claim in any manner whatsoever,
that the MHR Group is, or previously became, an Acquiring Person, in each case, based on, relating to, or concerning, any event, action, conduct, discussion or communication that has occurred prior to the date hereof; 

(b) (i) agrees that entering into this Agreement or exercising any rights under Section 1(a)(ii) or
1(c)(iii) of this Agreement shall not result in the MHR Group having previously become, or becoming, an Acquiring Person (as defined in the Rights Agreement or any provision having a similar effect under any New Rights Plan (as
defined below)), and (ii) waives, as of the date hereof and at such later time, any right available to the Company under the Rights Agreement that could allow the Company to assert or declare that any matter referred to in clause (b)(i)

 (c) agrees that the agreements and
waivers set forth in clauses (a) and (b) above by the Company shall constitute a determination and interpretation by the Board pursuant to Section 29 of the Rights Agreement for the purpose of administering the Rights Agreement;

 (d) within four (4) business days following the date hereof, agrees to file with the SEC a fully executed copy of
Amendment No. 5 (“Amendment No. 5”) to the Rights Agreement in substantially the form attached hereto as Exhibit E and dated and effective as of the date hereof, which form of amendment has been approved by the
Board on or prior to the date hereof; and 
 (e) so long as an MHR Nominee is a member of the Board, and except for Amendment
No. 5, agrees not to (i) amend, modify, supplement or replace the Rights Agreement, except for any amendment, modification or supplement the sole purpose of which is to extend the expiration date of the Rights Agreement, or (ii) adopt
a New Rights Plan, that, in each case, would be inconsistent with, or restrict the rights, powers, or privileges created by this Section 5 (including but not limited to the Rights Agreement) unless such
amendment, modification, supplement, replacement or New Rights Plan is approved by a majority of the Board, which majority shall include (x) at least one MHR Nominee and (y) provided that an Other Shareholder Nominee is a member of the
Board, at least one Other Shareholder Nominee. For purposes of this Agreement, a “New Rights Plan” shall mean any plan or arrangement (including any related rights agreement) of the sort commonly referred to as a “rights plan” or
“stockholder rights plan” or “shareholder rights plan” or “poison pill” that is designed to prevent or make more difficult a hostile takeover of the corporation by increasing the cost to a potential acquirer in such a
takeover either through the issuance of new rights, shares of common stock or preferred stock or any other security or device that may be issued to stockholders of the corporation other than ratably to all stockholders of the corporation that carry
severe redemption provisions, favorable purchase provisions or otherwise, and any related rights agreement.

7. Other Shareholder Agreement. From and after the date hereof, so long as an MHR Nominee is a member of the Board, the Company
agrees that if it amends, modifies or waives the Other Shareholder Agreement or grants any rights, or otherwise enters into any arrangement, agreement or understanding with the Other Shareholder relating to the types of matters contemplated by this
Agreement or any exhibits hereto that provide any right more favorable than those set forth in this Agreement, that the Company shall offer the same rights to the MHR Group.

 11. Miscellaneous. The parties hereto recognize and agree that if for any reason any
of the provisions of this Agreement are not performed in accordance with their specific terms or are otherwise breached, immediate and irreparable harm or injury would be caused for which money damages would not be an adequate remedy. Accordingly,
each party agrees that in addition to other remedies the other party shall be entitled to at law or equity, the other party shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms
and provisions of this Agreement exclusively in the Court of Chancery or other federal or state courts of the State of Delaware. In the event that any action shall be brought in equity to enforce the provisions of this Agreement, no party shall
allege, and each party hereby waives the defense, that there is an adequate remedy at law. Furthermore, each of the parties hereto (a) consents to submit itself to the personal jurisdiction of the Court of Chancery or other federal or state
courts of the State of Delaware in the event any dispute arises out of this Agreement or the transactions contemplated by this Agreement, (b) agrees that it shall not attempt to deny or defeat such personal jurisdiction by motion or other
request for leave from any such court, (c) agrees that it shall not bring any action relating to this Agreement or the transactions contemplated by this Agreement in any court other than the Court of Chancery or other federal or state courts of

TO THE CHOICE OF LAW PRINCIPLES OF SUCH STATE. 
 12. No Waiver. Any waiver by any party of a breach of any provision of
this Agreement shall not operate as or be construed to be a waiver of any other breach of such provision or of any breach of any other provision of this Agreement. The failure of a party to insist upon strict adherence to any term of this Agreement
on one or more occasions shall not be considered a waiver or deprive that party of the right thereafter to insist upon strict adherence to that term or any other term of this Agreement. 

13. Entire Agreement. The Agreement, as amended and restated in its entirety by this Amendment, and the Confidentiality Agreement
contain the entire understanding of the parties with respect to the subject matter hereof and may be amended only by an agreement in writing executed by the parties hereto.

 NAVISTAR INTERNATIONAL CORPORATION

 [            ], 201[     ] 

To: [Each of the persons or entities listed on Schedule A hereto (the “MHR Group”)] 

Ladies and Gentlemen: 
 This
letter agreement shall become effective upon the appointment of any MHR Nominee to the Board of Directors (the “Board”) of Navistar International Corporation (the “Company”) at which time the parties shall execute
the signature page hereto. Capitalized terms used but not otherwise defined herein shall have the meanings given to such terms in the Settlement Agreement (the “Settlement Agreement”), effective as of October 5, 2012, among the
Company and the MHR Group, as amended and restated in its entirety by Amendment No. 1, effective as of July [•], 2013. The Company understands and agrees that, subject to the terms of, and in accordance with, this letter agreement, the MHR
Nominee may, if and to the extent he or she desires to do so (in his or her sole and absolute discretion), disclose information he or she obtains while a member of the Board to you and your Representatives (as hereinafter defined) and to any
Designating Person that has executed a confidentiality agreement with the Company and its attorneys, directors, officers and employees subject to such confidentiality agreement, and may discuss such information with any and all such persons. As a
result, you may receive certain non-public information regarding the Company. You acknowledge that this information is proprietary to the Company and may include trade secrets or other business information the disclosure of which could harm the
Company. In consideration for, and as a condition of, the information being furnished to you and, subject to the restrictions in paragraph 2, your attorneys, directors, officers and employees (collectively, the
“Representatives”), you agree to treat any and all information concerning the Company or any of its subsidiaries or affiliates that is furnished to you or your Representatives (regardless of the manner in which it is furnished,
including without limitation in written or electronic format or orally, gathered by visual inspection or otherwise) by any MHR Nominee, or by or on behalf of the Company, together with any notes, analyses, reports, models, compilations, studies,
interpretations, documents, records or extracts thereof containing, referring, relating to, based upon or derived from such information, in whole or in part (collectively, “Evaluation Material”), in accordance with the provisions of
this letter agreement, and to take or abstain from taking the other actions hereinafter set forth. The term “Designating Person” shall mean any Person that has entered into an agreement with the Company pursuant to which such person
has the right to designate one or more members of the Board and a designee of such Person is serving as a member of the Board at such time. 
 1. The term “Evaluation Material” does not include information that (i) is or has become generally available to the public other than as a result of a direct or indirect disclosure by you
or your Representatives in violation of this letter agreement or any obligation of confidentiality, (ii) was within your or any of your Representatives’ possession on a non-confidential basis prior to its being furnished to you by any MHR
Nominee, or by or on behalf of the Company or its agents, representatives, attorneys, advisors, directors, officers or employees 

 
(collectively, the “Company Representatives”) or (iii) is received from a source other than any MHR Nominee, the Company or any of the Company Representatives;
provided, that in the case of (ii) or (iii) above, the source of such information was not believed to you, after reasonable inquiry of the disclosing person, to be bound by a confidentiality agreement with or other contractual,
legal or fiduciary obligation of confidentiality to the Company or any other person with respect to such information at the time the same was disclosed. 
 2. You and your Representatives will, and you will cause your Representatives to, (a) keep the Evaluation Material strictly confidential and (b) not disclose any of the Evaluation Material in
any manner whatsoever without the prior written consent of the Company; provided, however, that you may disclose any of such information: (A) to your Representatives (i) who need to know such information for the sole purpose
of advising you and (ii) who are informed by you of the confidential nature of such information; provided, further, that you will be responsible for any violation of this letter agreement by your Representatives as if they were
parties hereto, except that you will not be so responsible with respect to any such Representative who has executed a copy of this letter agreement as an Additional Signatory and delivered such signed copy to the Company or (B) to any
Designating Person who has executed a copy of a confidentiality agreement with the Company and its attorneys, directors, officers and employees subject to such confidentiality agreement. It is understood and agreed that no MHR Nominee shall disclose
to you or your Representatives any Legal Advice (as defined below) that may be included in the Evaluation Material with respect to which such disclosure would constitute waiver of the Company’s attorney client privilege or attorney work product
privilege; provided, however, that an MHR Nominee may provide such disclosure if such MHR Nominee shall not have taken any action, or failed to take any action, that has the purpose or effect of waiving attorney-client privilege or
attorney work product privilege with respect to any portion of such Legal Advice and if reputable outside legal counsel of national standing provides the Company with a written opinion that such disclosure will not waive the Company’s attorney
client privilege or attorney work product privilege with respect to such Legal Advice. “Legal Advice” as used herein shall be solely and exclusively limited to the advice provided by legal counsel and shall not include factual information
or the formulation or analysis of business strategy. 
 3. In the event that you or any of your Representatives are required by
applicable subpoena, legal process or other legal requirement to disclose any of the Evaluation Material, you will promptly notify (except where such notice would be legally prohibited) the Company in writing by facsimile and certified mail so that
the Company may seek a protective order or other appropriate remedy (and if the Company seeks such an order, you will provide such cooperation as the Company shall reasonably request), at its cost and expense. Nothing herein shall be deemed to
prevent you or your Representatives, as the case may be, from honoring a subpoena, legal process or other legal requirement that requires discovery, disclosure or production of the Evaluation Material if (a) you produce or disclose only that
portion of the Evaluation Material which your outside legal counsel of national standing advises you is legally required to be so produced or disclosed and you inform the recipient of such Evaluation Material of the existence of this letter
agreement and the confidential nature of such Evaluation Material; or (b) the Company consents in writing to having the Evaluation Material produced or disclosed pursuant to the subpoena, legal process or other legal requirement. In no event
will you or any of your Representatives oppose action by the Company to obtain a protective order or other relief to prevent the disclosure of the Evaluation Material or to obtain reliable assurance that confidential

 
treatment will be afforded the Evaluation Material. It is understood that there shall be no “legal requirement” requiring you to disclose any Evaluation Material solely by virtue of the
fact that, absent such disclosure, you would be prohibited from purchasing, selling, or engaging in derivative or other transactions with respect to, the Common Stock of the Company or otherwise proposing or making an offer to do any of the
foregoing or making any offer, including any tender offer, or you would be unable to file any proxy materials in compliance with Section 14(a) of the Exchange Act or the rules promulgated thereunder. 

4. You acknowledge that (a) none of the Company or any of the Company Representatives makes any representation or warranty, express
or implied, as to the accuracy or completeness of any Evaluation Material, and (b) none of the Company or any of the Company Representatives shall have any liability to you or to any of your Representatives relating to or resulting from the use
of the Evaluation Material or any errors therein or omissions therefrom. You and your Representatives shall not directly or indirectly initiate contact or communication with any executive or employee of the Company other than the Chief Executive
Officer, Chief Financial Officer and Chief Operating Officer concerning Evaluation Material, or to seek any information in connection therewith from any such person other than the Chief Executive Officer, Chief Financial Officer and Chief Operating
Officer, without the prior consent of the Company; provided, however, the restriction in this sentence shall not in any way apply to any MHR Nominee or other Board members. 
 5. All Evaluation Material shall remain the property of the Company. Neither you nor any of your Representatives shall by virtue of any disclosure of and/or your use of any Evaluation Material acquire any
rights with respect thereto, all of which rights (including all intellectual property rights) shall remain exclusively with the Company. At any time after the date on which no MHR Nominee is a director of the Company, upon the request of the Company
for any reason, you will promptly return to the Company all hard copies of the Evaluation Material and use commercially reasonable efforts to permanently erase or delete all electronic copies of the Evaluation Material in your or any of your
Representatives’ possession or control (and, upon the request of the Company, shall certify to the Company that such Evaluation Material has been erased or deleted, as the case may be). Notwithstanding the return or erasure or deletion of
Evaluation Material, you and your Representatives will continue to be bound by the obligations contained herein. 
 6. You
acknowledge, and will advise your Representatives, that the Evaluation Material may constitute material non-public information under applicable federal and state securities laws, and that you shall not, and you shall use your commercially reasonable
efforts to ensure that your Representatives, do not, trade or engage in any derivative or other transaction, on the basis of such information in violation of such laws. 
 7. You hereby represent and warrant to the Company that (i) you have all requisite company power and authority to execute and deliver this letter agreement and to perform your obligations hereunder,
(ii) this letter agreement has been duly authorized, executed and delivered by you, and is a valid and binding obligation, enforceable against you in accordance with its terms, (iii) this Agreement will not result in a violation of any
terms or conditions of any agreements to which you are a party or by which you may otherwise be bound or of any law, rule, license, regulation, judgment, order or decree governing or affecting you, and (iv) your entry into this Agreement does
not require approval by any owners or holders of any equity interest in you (except as has already been obtained). 

 8. Any waiver by the Company of a breach of any provision of this letter agreement shall not
operate as or be construed to be a waiver of any other breach of such provision or of any breach of any other provision of this letter agreement. The failure of the Company to insist upon strict adherence to any term of this letter agreement on one
or more occasions shall not be considered a waiver or deprive the Company of the right thereafter to insist upon strict adherence to that term or any other term of this letter agreement. 

9. You acknowledge and agree that the value of the Evaluation Material to the Company is unique and substantial, but may be impractical
or difficult to assess in monetary terms. You further acknowledge and agree that in the event of an actual or threatened violation of this letter agreement, immediate and irreparable harm or injury would be caused for which money damages would not
be an adequate remedy. Accordingly, you acknowledge and agree that, in addition to any and all other remedies which may be available to the Company at law or equity, the Company shall be entitled to an injunction or injunctions to prevent breaches
of this letter agreement and to enforce specifically the terms and provisions of this letter agreement exclusively in the Court of Chancery or other federal or state courts of the State of Delaware. In the event that any action shall be brought in
equity to enforce the provisions of this letter agreement, you shall not allege, and you hereby waive the defense, that there is an adequate remedy at law. 
 10. Each of the parties hereto (a) consents to submit itself to the personal jurisdiction of the Court of Chancery or other federal or state courts of the State of Delaware in the event any dispute
arises out of this letter agreement or the transactions contemplated by this letter agreement, (b) agrees that it shall not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court,
(c) agrees that it shall not bring any action relating to this letter agreement or the transactions contemplated by this letter agreement in any court other than the Court of Chancery or other federal or state courts of the State of Delaware,
and each of the parties irrevocably waives the right to trial by jury, (d) agrees to waive any bonding requirement under any applicable law, in the case any other party seeks to enforce the terms by way of equitable relief, and
(e) irrevocably consents to service of process by a reputable overnight delivery service, signature requested, to the address of such party’s principal place of business or as otherwise provided by applicable law. THIS LETTER AGREEMENT
SHALL BE GOVERNED IN ALL RESPECTS, INCLUDING WITHOUT LIMITATION VALIDITY, INTERPRETATION AND EFFECT, BY THE LAWS OF THE STATE OF DELAWARE APPLICABLE TO CONTRACTS EXECUTED AND TO BE PERFORMED WHOLLY WITHIN SUCH STATE WITHOUT GIVING EFFECT TO THE
CHOICE OF LAW PRINCIPLES OF SUCH STATE. 
 11. This letter agreement and the Amendment contain the entire understanding of the
parties with respect to the subject matter hereof and thereof and this letter agreement may be amended only by an agreement in writing executed by the parties hereto. 
 12. All notices, consents, requests, instructions, approvals and other communications provided for herein and all legal process in regard hereto shall be in writing and shall be deemed

 RIGHTS AGREEMENT 

This Amendment No. 5 (this “Amendment”) is dated as of July 14, 2013 (the “Effective Date”), and

 Exhibit A 
 FORM OF 
 SUMMARY OF RIGHTS TO PURCHASE 

PREFERRED STOCK 

On June 19, 2012, the Board of Directors (the “Board”) of Navistar International Corporation, a Delaware corporation (the
“Company”), authorized and declared a dividend distribution of one right (a “Right”) for each outstanding share of the common stock of the Company, par value $0.10 per share (the “Common Stock”), to stockholders of
record at the close of business on June 29, 2012 (the “Record Date”). Each Right entitles the registered holder to purchase from the Company a unit consisting of one one-thousandth of a share (a “Unit”) of a newly authorized
series of Junior Participating Preferred Stock, Series A, par value $1.00 per share (the “Preferred Stock”), at a purchase price of $140.00 per Unit, subject to adjustment (the “Purchase Price”). The complete terms of the Rights
are set forth in a Rights Agreement, dated as of June 19, 2012, as amended to date, between the Company and Computershare Inc., successor-in-interest to Computershare Shareowner Services LLC, as Rights Agent (the “Rights Agreement”).

 Rights Certificates; Exercise Period. 
 Initially, the Rights will be attached to all shares of Common Stock then outstanding, and no separate rights certificates (“Rights Certificates”) will be distributed. Subject to certain
exceptions specified in the Rights Agreement, the Rights will separate from the Common Stock and a distribution date (a “Distribution Date”) will occur upon the earlier of (i) 10 business days following a public announcement that a
person or group of affiliated or associated persons (an “Acquiring Person”) has acquired beneficial ownership of twenty percent (20%) or more of the outstanding shares of Common Stock (the “Stock Acquisition Date”), other
than as a result of repurchases of stock by the Company or certain inadvertent actions by certain stockholders or (ii) 10 business days (or such later date as the Board shall determine) following the commencement of a tender offer or exchange
offer that would result in a person or group becoming an Acquiring Person. For purposes of the Rights Agreement, beneficial ownership is defined to include ownership of derivative securities. 

Until a Distribution Date, (i) the Rights will be evidenced by the certificates for the Common Stock (or, in the case of shares
reflected on the direct registration system, by the notations in the book-entry account system) and will only be transferable with such Common Stock, (ii) new Common Stock certificates issued after the Record Date will contain a legend
incorporating the Rights Agreement by reference and (iii) the surrender for transfer of any certificates for Common Stock outstanding will also constitute the transfer of the Rights associated with the Common Stock represented by such
certificates. Pursuant to the Rights Agreement, the Company reserves the right to require prior to the occurrence of a Triggering Event (as defined below) that, upon any exercise of Rights, a number of Rights be exercised so that only whole shares
of Preferred Stock will be issued. 
 The Rights are not exercisable until a Distribution Date and will expire at 5:00 P.M., New
York City time on June 18, 2015, unless such date is extended or the Rights are earlier redeemed, exchanged or terminated. 

 As soon as practicable after a Distribution Date, Rights Certificates will be mailed to
holders of record of the Common Stock as of the close of business on a Distribution Date and, thereafter, the separate Rights Certificates alone will represent the Rights. Except as otherwise determined by the Board, only shares of Common Stock
issued prior to a Distribution Date will be issued with Rights. 
 Flip-in Trigger. 

In the event that a person or group of affiliated or associated persons becomes an Acquiring Person, except pursuant to an offer for all
outstanding shares of Common Stock which the independent directors determine to be fair and not inadequate and to otherwise be in the best interests of the Company and its stockholders after receiving advice from one or more investment banking
firms, each holder of a Right will thereafter have the right to receive, upon exercise, Common Stock (or, in certain circumstances, cash, property or other securities of the Company) having a value equal to two times the exercise price of the Right.
Notwithstanding the foregoing, following the occurrence of the event set forth in this paragraph, all Rights that are, or (under certain circumstances specified in the Rights Agreement) were, beneficially owned by any Acquiring Person will be null
and void. However, Rights are not exercisable following the occurrence of the event set forth above until such time as the Rights are no longer redeemable by the Company as set forth below. Any person who, together with its affiliates and
associates, beneficially owns 20% or more of the outstanding shares of Common Stock as of the time of first public announcement of the Rights Agreement (an “Exempt Person”) shall not be deemed an Acquiring Person, but only for so long as
such person, together with its affiliates and associates, does not, while such person is an Exempt Person, become the Beneficial Owner of a higher percentage of the shares of Common Stock then outstanding (other than as a result of a reduction in
the number of shares of Common Stock outstanding due to the repurchase of Common Stock by the Company (or any Subsidiary of the Company, any employee benefit plan of the Company or any Subsidiary of the Company, or any Person or entity organized,
appointed or established by the Company for or pursuant to the terms of any such plan)) as compared to the percentage of shares of Common Stock outstanding Beneficially Owned by such Exempt Person as of the Exempt Time. 

Flip-over Trigger. 
 In the event that, at any time following the Stock Acquisition Date, (i) the Company engages in a merger or other business combination transaction in which the Company is not the surviving
corporation, (ii) the Company engages in a merger or other business combination transaction in which the Company is the surviving corporation and the Common Stock of the Company is changed or exchanged, or (iii) 50% or more of the
Company’s assets, cash flow or earning power is sold or transferred, each holder of a Right (except Rights which have previously been voided as set forth above) shall thereafter have the right to receive, upon exercise, common stock of the
acquiring company having a value equal to two times the exercise price of the Right. The events set forth in this paragraph and in the preceding paragraph are referred to as the “Triggering Events.” 

  
 2 

 Exchange Feature. 

At any time after a person becomes an Acquiring Person and prior to the acquisition by such person or group of fifty percent
(50%) or more of the outstanding Common Stock, the Board may exchange the Rights (other than Rights owned by such person or group which have become null and void), in whole or in part, at an exchange ratio of one share of Common Stock, or one
one-thousandth of a share of Preferred Stock (or of a share of a class or series of the Company’s preferred stock having equivalent rights, preferences and privileges), per Right (subject to adjustment). 

Equitable Adjustments. 
 The Purchase Price payable, and the number of Units of Preferred Stock or other securities or property issuable, upon exercise of the Rights are subject to adjustment from time to time to prevent dilution
(i) in the event of a dividend on the Preferred Stock payable in shares of Preferred Stock, a subdivision or split of outstanding shares of Preferred Stock, a combination or consolidation of Preferred Stock into a smaller number of shares
through a reverse stock split or otherwise, or reclassification of the Preferred Stock, (ii) if holders of the Preferred Stock are granted certain rights, options or warrants to subscribe for Preferred Stock or convertible securities at less
than the current market price of the Preferred Stock, or (iii) upon the distribution to holders of the Preferred Stock of cash (excluding regular quarterly cash dividends), assets, evidences of indebtedness or of subscription rights or warrants
(other than those referred to above). 
 With certain exceptions, no adjustment in the Purchase Price will be required until
cumulative adjustments amount to at least 1% of the Purchase Price. No fractional Units will be issued and, in lieu thereof, an adjustment in cash will be made based on the market price of the Preferred Stock on the last trading date prior to the
date of exercise. 
 Redemption Rights. 
 At any time until ten business days following the Stock Acquisition Date, the Company may redeem the Rights in whole, but not in part, at a price of $0.001 per Right (payable in cash, Common Stock or
other consideration deemed appropriate by the Board). Immediately upon the action of the Board ordering redemption of the Rights, the Rights will terminate and the only right of the holders of Rights will be to receive the $0.001 redemption price.

 Miscellaneous. 
 Until a Right is exercised, the holder thereof, as such, will have no separate rights as a stockholder of the Company, including, without limitation, the right to vote or to receive dividends in respect
of Rights. While the distribution of the Rights will not be taxable to stockholders or to the Company, stockholders may, depending upon the circumstances, recognize taxable income in the event that the Rights become exercisable for Common Stock (or
other consideration) of the Company or for common stock of the acquiring company or in the event of the redemption of the Rights as set forth above. 
 Amendment. 
 Any of the provisions of the Rights Agreement may be amended
by the Board prior to a Distribution Date. After a Distribution Date, the provisions of the Rights Agreement may be 

  
 3 

 
amended by the Board in order to cure any ambiguity, to make changes which do not adversely affect the interests of holders of Rights, or to shorten or lengthen any time period under the Rights
Agreement. Notwithstanding the foregoing, no amendment may be made (other than to cure any ambiguity) at a time when the Rights are not redeemable. 
 Anti-Takeover Effects. 
 The Rights may have certain anti-takeover effects.
The Rights may cause substantial dilution to any person or group that attempts to acquire the Company without the approval of the Board. As a result, the overall effect of the Rights may be to render more difficult or discourage a merger, tender
offer or other business combination involving the Company that is not supported by the Board. 
 A copy of the Rights Agreement
has been filed with the Securities and Exchange Commission as an Exhibit to a Registration Statement on Form 8-A or a Current Report on Form 8-K. A copy of the Rights Agreement is available free of charge from the Company. This summary description
of the Rights does not purport to be complete and is qualified in its entirety by reference to the Rights Agreement, which is incorporated herein by reference.

 EXHIBIT F 
 AGREEMENT 
 This Agreement (the “Agreement”) is made and
entered into as of July 14, 2013, by and among the persons and entities listed on Schedule A hereto (each, individually, an “MHR Entity” and collectively, the “MHR Entities”) and Navistar International Corporation,
a Delaware corporation (the “Company”). 
 WHEREAS, the MHR Entities and their respective affiliates and
associates may desire to acquire ownership of additional shares of common stock, par value $.01 per share, of the Company (“Common Stock”) without being subject to the restrictions under Section 203 of the General Corporation
Law of the State of Delaware (“DGCL 203”) applicable to a “business combination” with an “interested stockholder” (each such term, as used in this Agreement, shall have the meaning given to it in DGCL 203, except
as described in Section 4 hereof), so long as the MHR Entities and their affiliates and associates do not own 20% or more of the voting power of the then issued and outstanding shares of voting stock of the Company; 

WHEREAS, as of the date hereof, the Company and the MHR Entities have no current discussions or negotiations with each other regarding a
business combination or other extraordinary transaction involving the Company; 
 NOW THEREFORE, in consideration of the
premises and the covenants of the parties set forth in this agreement, and for other good and valuable consideration the receipt and adequacy of which are hereby acknowledged, and intending to be legally bound, the undersigned hereby agree as
follows: 
 1. The Company hereby represents and warrants to the MHR Entities that the Board of Directors of the Company has
duly approved (the “Board Approval”) this Agreement and the acquisition by the MHR Entities and their respective affiliates and associates, whether in a single transaction or multiple transactions from time to time, of additional
shares of Common Stock to the extent such acquisitions would result in the MHR Entities and their affiliates and associates being the owner of 15% or more, but less than 20%, of the voting power of the shares of voting stock of the Company issued
and outstanding from time to time, subject to the limitations provided for in Section 4 hereof and subject to the accuracy of the representations and warranties set forth in Section 2 hereof. 

2. The MHR Entities hereby represent and warrant that, as of the date of this Agreement and assuming the accuracy of the representations
and warranties set forth in Section 3 hereof, the MHR Entities and their affiliates and associates are, in the aggregate, owners of less than 15% of the shares of Common Stock issued and outstanding as of the date of this Agreement. 

3. The Company hereby represents and warrants that, as of the date of this Agreement, there are
             shares of Common Stock issued and outstanding which is the only class of “voting stock” (as defined herein) of the Company. 

  
 1 

 4. Each of the MHR Entities agrees that if any MHR Entity or any of its affiliates and
associates becomes the owner of shares of voting stock of the Company such that the MHR Entities would, together with their affiliates and associates, in the aggregate own 20% or more of the voting power of the issued and outstanding shares of
voting stock of the Company under circumstances in which they would be an “interested stockholder” as defined in DGCL 203 (but, for this purpose, replacing 15% in such definition with 20%) (any event causing the MHR Entities and their
affiliates and associates to own in the aggregate 20% or more of the voting power of the then issued and outstanding shares of voting stock of the Company, an “Additional Acquisition”), then (i) notwithstanding the Board Approval
referred to in Section 1 of this Agreement, the restrictions under DGCL 203 applicable to a “business combination” with an “interested stockholder” shall apply as a matter of contract pursuant to this Agreement (except as
modified herein) to the MHR Entities and their respective affiliates and associates as if such Board Approval had not been granted and as if the Additional Acquisition had caused each MHR Entity and its affiliates and associates to become an
interested stockholder for purposes of DGCL 203, except that wherever 15% is used in DGCL 203 it shall mean, for all purposes of this Agreement, 20%; and (ii) the MHR Entities and their affiliates and associates will not engage in any business
combination with the Company for a period of 3 years following the time that the MHR Entities and their affiliates and associates became an owner of 20% or more of the voting power of the then issued and outstanding shares of voting stock of the
Company, unless: 
 (1) prior to such time the Board of Directors of the Company approved, including approval by a majority of
the Non-MHR Directors (as defined in Section 5), either the business combination or the Additional Acquisition; 
 (2) upon
consummation of the transaction which resulted in the MHR Entities and their affiliates and associates becoming an owner of 20% or more of the voting power of the issued and outstanding shares of voting stock of the Company, the MHR Entities and
their affiliates and associates owned at least 85% of the voting power of the voting stock of the Company outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock outstanding (but not the outstanding
voting stock owned by the MHR Entities and their affiliates and associates) those shares owned (i) by persons who are directors and also officers of the Company and (ii) employee stock plans in which employee participants do not have the
right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or 

(3) at or subsequent to such time the business combination is approved by the Board of Directors of the Company, including by a majority
of the Non-MHR Directors, and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the voting power of the outstanding voting stock which is not owned by the MHR
Entities and their affiliates and associates; 
 provided, that, the restrictions set forth above shall not apply if any of the exceptions in
DGCL Section 203(b)(4), (5) or (6) would be applicable at the time of such business combination. 
 5. This
Agreement may be executed in counterparts, each of which shall be deemed to be an original, with the same effect as if the signatures were upon the same instrument. All representations, warranties, covenants and agreements made herein shall survive

  
 2 

 
the execution and delivery of this Agreement. This Agreement constitutes the entire agreement among the parties hereto in respect of the subject matter hereof. No provision of this Agreement may
be: (a) amended except by an instrument in writing executed by the parties hereto; or (b) waived except by an instrument in writing executed by the party against whom the waiver is to be effective; provided that any such amendment or
waiver has been approved by the Board of Directors of the Company, including, to the fullest extent permitted by law, by a majority of the Non-MHR Directors. This Agreement shall not be terminated except by an instrument in writing executed by the
parties hereto; provided that any such termination has been approved by the Board of Directors of the Company, including, to the fullest extent permitted by law, by a majority of the Non-MHR Directors. For purposes of this Agreement,
“Non-MHR Directors” shall mean the members of the Board of Directors of the Company that are not affiliated with, and were not nominated by, any MHR Entity or any affiliate or associate thereof or any other stockholder of the
Company (including any affiliate or associate of any such stockholder) that is subject to an agreement similar to this Agreement. This Agreement: (i) shall not be assignable by any of the parties hereto; and (ii) shall be binding on
successors of the parties hereto. 
 6. This Agreement shall be governed by, and construed and interpreted in accordance with,
the laws of the State of Delaware, without regard to choice of law principles that would compel the application of the laws of any other jurisdiction. Each of the parties hereto irrevocably agrees that any legal action or proceeding that may be
based upon, arise out of or relate to this Agreement or the negotiation, execution or performance hereof, shall be brought and determined exclusively in the Chancery Court of the State of Delaware and any state appellate court therefrom located in
the State of Delaware (or, only if the Chancery Court of the State of Delaware declines to accept jurisdiction over a particular matter, any state or federal court located in the State of Delaware). 

7. Each of the parties hereto hereby irrevocably waives any and all rights to trial by jury in any legal proceeding arising out of or
related to this Agreement. 
 8. The parties hereto agree that irreparable damage, for which monetary damages would not be an
adequate remedy, would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached by the parties hereto. It is accordingly agreed that the parties hereto
shall be entitled to an injunction or injunctions, or any other appropriate form of specific performance or equitable relief, to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of competent
jurisdiction, this being in addition to any other remedy to which they are entitled under the terms of this Agreement at law or in equity. Each party hereto accordingly agrees not to raise any objections to the availability of the equitable remedy
of specific performance to prevent or restrain breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of such party under this Agreement. 

9. The parties hereto have participated jointly in the negotiation and drafting of this Agreement and, in the event an ambiguity or
question of intent or interpretation arises, this Agreement shall be construed as jointly drafted by the parties hereto and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision
of this Agreement.

 10. As used in this Agreement, the terms “affiliate,”
“associate,” “owner,” including the terms “own” and “owned,” “stock” and “voting stock” have the meanings given to them in DGCL 203; provided, that
(a) the MHR Entities and their affiliates and associates shall not be deemed to be an “owner” of, or to “own” or have “owned,” any stock owned by any “Permitted Person” solely by
virtue of engaging in a “Permitted Activity” with such Permitted Person, as such terms are currently defined in Amendment No. 1 to Rights Agreement, dated as of October 5, 2012, between the Company and Computershare Inc., a
Delaware corporation, successor-in-interest to Computershare Shareowner Services LLC, a New Jersey limited liability company, as rights agent, as in effect on the date hereof, and (b) for the avoidance of doubt, the Company’s
Nonconvertible Junior Preference Stock, Series B, par value $1.00 per share, and the Company’s Convertible Junior Preference Stock, Series D, par value $1.00 per share, each with the rights currently set forth in the Company’s certificate
of incorporation in effect on the date hereof, shall not be deemed to be voting stock for purposes of this Agreement. 
 11.
This Agreement is intended to benefit, and shall be enforceable by, each holder of outstanding shares of capital stock of the Company as a third-party beneficiary of this Agreement, such that such stockholders shall be entitled to enforce the
Agreement if any of the provisions of this Agreement were not performed in accordance with their specific terms, as amended from time to time in accordance with Section 5 hereof, or were otherwise breached by the parties hereto, including,
without limitation, in the event any business combination were consummated in violation of Section 4 hereof, as amended from time to time in accordance with Section 5 hereof, other than any consummation thereof pursuant to a waiver
obtained in accordance with Section 5 hereof.
