Re: Herbalife Tender Offer and Standstill

Ladies and Gentlemen:

This letter agreement (this “Agreement”) memorializes the agreement between Herbalife Ltd., a Cayman Islands exempt company incorporated with limited liability (the “Company”), on the one hand, and Mr. Carl C. Icahn and each of the other signatories hereto, (collectively, the “Icahn Affiliates”), on the other hand, relating to that certain modified Dutch auction tender offer (the “Offer”) to be commenced by the Company on or about August 21, 2017.

In consideration of and in reliance upon the mutual covenants and agreements contained in this Agreement, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, by signing this Agreement, the parties hereby agree and acknowledge as follows:

Standstill

Reference is made to the Contingent Value Rights Agreement by and between the Company and Computershare Trust Company, N.A., as contingent value rights agent, the form of which is attached hereto as Exhibit A (the “CVR Agreement”) to be executed at the consummation of the Offer. The Icahn Affiliates agree that prior to the Contingent Value End Date, as defined in the CVR Agreement, the Icahn Affiliates will not purchase or otherwise acquire Herbalife shares that would cause an increase such that their aggregate beneficial ownership (as defined in Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Regulation 13D promulgated thereunder) exceeds 50% of the outstanding Herbalife shares, unless the Icahn Affiliates simultaneously purchase or otherwise agree to acquire 100% of the outstanding Herbalife shares. Notwithstanding the foregoing, for the avoidance of doubt, the obligation of the Icahn Affiliates contained in the foregoing sentence will not be triggered by a reduction in the number of outstanding Herbalife shares. Each Icahn Affiliate shall cause its controlled Affiliates (other than the Company) and Representatives to comply with the terms of this Agreement.

For the avoidance of any doubt, the reference to Icahn Affiliates above does not include the Company. For purposes of this Agreement, the “50% of the outstanding Herbalife shares” shall be calculated using the number of the Company’s outstanding common shares as reported by the Company on the cover of its most recent Form 10-K or Form 10-Q, as filed with the U.S. Securities and Exchange Commission (“SEC”). Lastly, nothing set forth herein shall in any way supersede or otherwise amend or modify the Second Amended and Restated Support Agreement (the “Second A&R Support Agreement”) dated July 15, 2016 between the Company and the Icahn Affiliates which shall remain in full force and effect.

Representations and Warranties of the Company

The Company represents and warrants to the Icahn Affiliates that (a) the Company has the corporate power and authority to execute this Agreement and to bind it thereto, (b) this Agreement has been duly and validly authorized, executed and delivered by the Company, constitutes a valid and binding obligation and agreement of the Company, and is enforceable against the Company in accordance with its terms, except as enforcement thereof may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or similar laws generally affecting the rights of creditors and subject to general equity principles and (c) the execution, delivery and performance of this Agreement by the Company does not and will not violate or conflict with (i) any law, rule, regulation, order, judgment or decree applicable to it or (ii) result in any breach or violation of or constitute a default (or an event which with notice or lapse of time or both could become a default) under or pursuant to, or result in the loss of a material benefit under, or give any right of termination, amendment, acceleration or cancellation of, any organizational document, agreement, contract, commitment, understanding or arrangement to which the Company is a party or by which it is bound.

Representations and Warranties of the Icahn Affiliates
