                              SIDE LETTER AGREEMENT

                  Reference is made to that certain Shareholders' Agreement
dated as of July 31, 2002, by and among the Company and certain of its
shareholders, including Kane, Hannah and the Institutional Shareholders (as the
same may be amended from time to time, the "Shareholders' Agreement").
Capitalized terms used in this Agreement without definition shall have the
meanings ascribed thereto in the Shareholders' Agreement.

                  Prior to the date hereof, (i) Kane purchased an aggregate of
284,091 Preferred Shares and (ii) Hannah purchased an aggregate of 568,182
Preferred Shares, respectively (the "Purchased Shares").

                  Concurrently with the execution of this Agreement, Kane and
Hannah are entering into separate Employment Agreements, of even date herewith,
with Herbalife International, Inc. and Herbalife International of America, Inc.,
which are direct or indirect wholly owned subsidiaries of the Company.

                  In consideration of, and as a condition to, Kane's and

undersigned desires to agree to certain modifications to the Shareholders'
Agreement with respect to the Purchased Shares.

                  Accordingly, each of the undersigned agrees:

provision to the contrary contained in Section 6 of the Shareholders' Agreement,
each of the undersigned agrees that the Institutional Shareholders and the
Company shall only be entitled to exercise their respective repurchase rights

Purchased Shares upon the termination of the relevant Employee Shareholder
(i.e., either Kane or Hannah, as the case may be) for Cause (as defined below)
or due to such Employee Shareholder's resignation (other than upon the
"Retirement" of such Employee Shareholder, as such term is defined in the Option
Agreements). For purposes of this Agreement, "Cause" shall have the meaning
ascribed to such term in any written employment agreement between the relevant
