       The Company is from time to time engaged in routine litigation.
       The Company regularly reviews all pending litigation matters in
       which it is involved and establishes reserves deemed appropriate
       by management for these litigation matters when a probable loss
       estimate can be made.

       As a marketer of dietary and nutritional supplements and other
       products that are ingested by consumers or applied to their
       bodies, the Company has been and is currently subjected to
       various product liability claims. The effects of these claims to
       date have not been material to the Company, and the reasonably
       possible range of exposure on currently existing claims is not
       material to the Company. The Company believes that it has
       meritorious defenses to the allegations contained in the
       lawsuits. The Company currently maintains product liability
       insurance with an annual deductible of $10&amp;#160;million.
   &lt;/div&gt;

       On April&amp;#160;16, 2007, Herbalife International of America, Inc.
       filed a Complaint in the United States District Court for the
       Central District of California against certain former Herbalife
       distributors who had left the Company to join a competitor. The
       Complaint alleged breach of contract, misappropriation of trade
       secrets, intentional interference with prospective economic
       advantage, intentional interference with contract, unfair
       competition, constructive trust and fraud and seeks monetary
       damages, attorney&amp;#8217;s fees and injunctive relief
       (&lt;i&gt;Herbalife International of America, Inc.&amp;#160;v. Robert E.
       Ford, et al&lt;/i&gt;). The court entered a Preliminary Injunction
       against the defendants enjoining them from further use
       &lt;font style="white-space: nowrap"&gt;and/or&lt;/font&gt;
       misappropriation of the Company&amp;#8217;s trade secrets on
       December&amp;#160;11, 2007. Defendants appealed the court&amp;#8217;s
       entry of the Preliminary Injunction to the U.S.&amp;#160;Court of
       Appeals for the Ninth Circuit. That court affirmed, in relevant
       part, the Preliminary Injunction. On December&amp;#160;3, 2007, the
       defendants filed a counterclaim alleging that the Company had
       engaged in unfair and deceptive business practices, intentional
       and negligent interference with prospective economic advantage,
       false advertising and that the Company was an endless chain
       scheme in violation of California law and seeking restitution,
       contract rescission and an injunction. Both sides engaged in
       discovery and filed cross motions for Summary Judgment. On
       August&amp;#160;25, 2009, the court granted partial summary judgment
       for Herbalife on all of defendants&amp;#8217; claims except the claim
       that the Company is an endless chain scheme which under
       applicable law is a question of fact that can only be determined
       at trial. The court denied defendants&amp;#8217; motion for Summary
       Judgment on Herbalife&amp;#8217;s claims for misappropriation of
       trade secrets and breach of contract. On May&amp;#160;5, 2010, the
       District Court granted summary judgment for Herbalife on
       defendants&amp;#8217; endless chain-scheme counterclaim. Herbalife
       voluntarily dismissed its remaining claims, and on May&amp;#160;14,
       2010, the District Court issued a final judgment dismissing all
       of the parties&amp;#8217; claims. On June&amp;#160;10, 2010 the
       defendants appealed from that judgment and on June&amp;#160;21,
       2010, Herbalife cross-appealed. The Company believes that there
       is merit to its appeal, and it will prevail upon both its appeal
       as well as the defendant&amp;#8217;s appeal.
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt; font-size: 1pt"&gt;&amp;#160;
   &lt;/div&gt;
   &lt;div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"&gt;
       Certain of the Company&amp;#8217;s subsidiaries have been subject to
       tax audits by governmental authorities in their respective
       countries. In certain of these tax audits, governmental
       authorities are proposing that significant amounts of additional
       taxes and related interest and penalties are due. The Company
       and its tax advisors believe that there are substantial defenses
       to their allegations that additional taxes are owed, and the
       Company is vigorously contesting the additional proposed taxes
       and related charges. On May&amp;#160;7, 2010, the Company received
       an administrative assessment from the Mexican Tax Administration
       Service in an amount equivalent to approximately
       $93&amp;#160;million, translated at the period ended spot rate, for
       various items, the majority of which was Value Added Tax
       allegedly owed on certain of the Company&amp;#8217;s products
       imported into Mexico during the years 2005 and 2006. This
       assessment is subject to interest and inflationary adjustments.
       On July&amp;#160;8, 2010, the Company initiated a formal
       administrative appeal process. In connection with the appeal of
       the assessment, the Company may be required to post bonds for
       some or all of the assessed amount. Therefore, in July 2010, the
       Company entered into agreements with certain insurance companies
       to allow for the potential issuance of surety bonds in support
       of its appeal of the assessment. Such surety bonds, if issued,
       would not affect the availability of the Company&amp;#8217;s existing
       credit facility. The Company did not record a provision as the
       Company, based on analysis and guidance from its advisors, does
       not believe a loss is probable. Further, the Company is
       currently unable to reasonably estimate a possible loss or range
       of loss that could result from an unfavorable outcome in respect
       to this assessment or any additional assessments
   that may be issued for these or other periods. The Company
       believes that it has meritorious defenses and is vigorously
       pursuing the appeal, but final resolution of this matter could
       take several years.
   &lt;/div&gt;
   &lt;div style="margin-top: 6pt; font-size: 1pt"&gt;&amp;#160;
   &lt;/div&gt;
   &lt;div align="left" style="margin-left: 0%; margin-right: 0%; text-indent: 4%; font-size: 10pt; font-family: 'Times New Roman', Times; color: #000000; background: transparent"&gt;
       These matters may take several years to resolve. While the
       Company believes it has meritorious defenses, it cannot be sure
       of their ultimate resolution. Although the Company has reserved
       amounts for certain matters that the Company believes represent
       the most likely outcome of the resolution of these related
       disputes, if the Company is incorrect in the assessment, the
       Company may have to record additional expenses, when it becomes
       probable that an increased potential liability is warranted.
   &lt;/div&gt;
   &lt;/div&gt;
