(c) the Assets are unencumbered, not subject to any lien, arrest, opposition, or any other charge or right of any third party, in particular no pre-emption rights which have not been duly waived or any other rights attached to the Assets by virtue of which any person may be entitled to demand that the Assets be transferred to him.

4

(d) the Beneficial Ownership of the Assets shall be validly contributed, converged and transferred by the Contributor to the Issuer upon holding of an extraordinary general meeting in the presence of a Luxembourg notary, whereby the Assets will be contributed to the Issuer against the issuance of the New Shares, without such transfer of Beneficial Ownership being conditional upon any other formalities to be carried out in any other jurisdiction

4.2 For the avoidance of doubt, the Issuer agrees that the Contributor was the stockholder of record on the record date for Navistar’s 2021 annual stockholder meeting (the “Annual Meeting”) and the Issuer therefore acknowledges that, for the sole purpose of the Annual Meeting, the right to vote at the Annual Meeting and any adjournments or postponements thereof shall remain with the Contributor.

4.3 The Issuer represents and warrants to the Contributor that at the Transfer Date:

(a) No General Solicitation.

(b) Investment Purpose. Issuer is acquiring the Assets pursuant to an exemption from registration under the Securities Act solely for its own account for investment purposes and not with a view to, or for offer or sale in connection with, any distribution thereof. The Issuer has acknowledged the Securities Act and any applicable state securities laws and acknowledges that the Assets may not be transferred or sold except pursuant to the registration provisions of the Securities Act or pursuant to an applicable exemption therefrom and subject to state securities laws and regulations, as applicable. Issuer has such knowledge and experience in business and financial matters so as to enable it to understand and evaluate the risks of and form an informed decision with respect to the herein envisaged contribution of the Assets and to protect its own interest in connection with such.

(c) Reliance on Exemptions. Issuer understands that the Assets are being contributed to it in reliance on one or more specific exemptions from the registration requirements of United States federal and state securities Laws and that the Contributor is relying upon the truth and accuracy of Issuer’s representations and warranties set forth in this Agreement to determine the availability of such exemption.

4.4 The Issuer covenants that, immediately following the Transfer Date and before it consummates the intended contribution of the Assets further to TRATON US Inc., a Delaware corporation wholly-owned by the Issuer (“TRATON US”), the Issuer will cause TRATON US to execute a joinder to the stockholder agreement entered into by and among the Contributor and Navistar on 5 September 2016.

4.5 The Issuer covenants that the New Shares shall be validly issued and allotted to the Contributor as fully paid up shares at the EGM.

5

5. ADDITIONAL ACTIONS

5.1 The Parties undertake to comply with any necessary formalities, make any necessary registrations, notifications, publications and/or filings and take any further action required in respect of the transfer of the Assets.

5.2 The Contributor undertakes to execute and deliver any documents and agreements and take any further actions deemed by the Contributor, Computershare Trust Company, N.A. (“Computershare”) or UniCredit to be necessary to record the transfer of the Assets from Contributor to TRATON US in the records of Computershare and UniCredit respectively.

6. NO WAIVER

No failure or delay of a Party to exercise any right or remedy under this Agreement shall be considered, or operate as, a waiver thereof, nor shall any single or partial exercise of any right or remedy preclude any other or further exercise thereof or the exercise of any other right or remedy.
