purchase agreement (the "JOINDER TO THE PURCHASE AGREEMENT") and a joinder to a
registration rights agreement (the "JOINDER TO THE REGISTRATION RIGHTS
AGREEMENT") by, inter alia, the Company as Herbalife Guarantor, all dated 31
July 2002, pursuant to which the Company provides guarantees for an indenture

- --------------------------------------------------------------------------------

2.    WE HAVE ASSUMED:

      Agreement are identical to the specimen reviewed by us and referred to in
      paragraphs 1(e) - (f) above;

(b)   the genuineness of all signatures (including the identity of the
      signatory) and the authenticity and completeness of all documents

      documents submitted to us as certified, conformed, photostatic or
      facsimile copies or by e-mail or other electronic transmission;

      within the capacity and powers of, the parties thereto (other than the

(f)   that the Purchase Agreement, being expressed to be construed by the laws
      of the State of New York, is governed by the laws of the State of New
      York;

(g)   that the Primary Documents constitute legally valid, binding and
      enforceable obligations of the parties thereto under the laws of the State
      of New York, being the laws by which such documents are expressed (or
      assumed) to be governed;

(h)   that there are no provisions of the laws (including, but not limited to,
      public policy or mandatory rules) of any jurisdiction other than Sweden
      which would have any implications on the opinion we express;

(i)   the accuracy and completeness of all factual representations made to us
      (other than in respect of matters on which we express our opinion herein),
      and therefore we have made no independent investigation thereof;

                              MANNHEIMER SWARTLING

                                            Stockholm, December 19, 2002    4(9)
- --------------------------------------------------------------------------------

(j)   that all necessary consents, authorisations and approvals whatsoever
      required in any relevant jurisdiction for the execution and performance of
      the Primary Documents by each of the parties thereto have been, or will
      be, obtained and that all necessary notices, filings, registrations and

      notices, filings, registrations and recordings required in any applicable
      jurisdiction (other than Sweden) in respect of the Guarantee Documents
      have been, or will be, given or effected in accordance with the laws and
      regulations of every such applicable jurisdiction;

(l)   that there are no provisions in, or other aspects of, any agreement or

      we express; and

(m)   that there has been no mutual or relevant unilateral mistake of fact and
      there exists no fraud, coercion or duress.

3.    ON THE BASIS OF THE FOREGOING AND SUBJECT TO THE QUALIFICATIONS AND
      RESERVATIONS HEREINAFTER SET FORTH, WE ARE OF THE OPINION THAT:

(a)   the Company is duly incorporated and validly existing as a limited
      liability company, possessing perpetual corporate existence and the
      capacity to sue and be sued in its own name, with full power, authority
      and legal right (corporate and other) to carry on business, to own
      property and to execute, and to perform all of its obligations under, the
      Guarantee Documents;

(b)   the Guarantee Documents have been duly authorised and duly executed and
      such documents constitute legally valid and binding obligations of the
      Company, enforceable against the Company in accordance with their terms
      under the laws of Sweden;

(c)   neither the execution by the Company of any Guarantee Document nor the
      performance by it of any of its obligations thereunder, nor the compliance

                              MANNHEIMER SWARTLING

                                            Stockholm, December 19, 2002    5(9)
- --------------------------------------------------------------------------------

      by it with the terms and conditions thereof, will:

      (i)   violate or result in any breach of, or constitute a default under,
            any applicable law, or

      (ii)  contravene or result in any breach of any provision of its Articles
            of Association; and

(d)   the choices of the law of the State of New York to govern the Operative
      Documents are valid and binding choices of law and will be recognised and
      applied by the courts of Sweden, upon proof of the relevant provisions of
      foreign law, subject, however, to the qualification that foreign laws will
      not be applied to the extent contrary to Swedish public policy and that
      Swedish law will be applied in a bankruptcy proceeding in respect of, or
      an execution against the Company.

4.    THE FOREGOING OPINION IS SUBJECT TO THE FOLLOWING QUALIFICATIONS AND
      RESERVATIONS:

(e)   anything contained in this opinion is subject to all limitations
      (including, but not limited to, stay, pre-emption rights, delays and
      recovery) resulting from bankruptcy, insolvency (including, but not
      limited to, the effects of the Council Regulation (EC) No. 1346/2000 of 29
      May 2000 on Insolvency Proceedings (the "EC INSOLVENCY REGULATION")),
      liquidation, reorganisation and similar laws affecting the rights of
      creditors generally;

(f)   if a Swedish company guarantees the obligations of another party without
      deriving any corporate benefit therefrom, the guarantee will only be valid
      up to the amount of the distributable reserves of the grantor at the time
      the guarantee is provided, and will require the consent of all
      shareholders; since the existence of corporate benefit is a question of
      fact, we do not express any opinion as to whether the Company will derive
      corporate benefit from guarantees provided under the Guarantee Documents;
      unless this is the case, the guarantees of the Company contained in the
      Guarantee Documents directly or indirectly for obligations owed by other
      parties, will be limited in validity as aforesaid;

(g)   a guarantee may be unenforceable if it is accessory to the obligations
      guaranteed, which means that should such obligations be unlawful, invalid
      or unenforceable, the guarantor may not be obliged to make payments under
      the guarantee;

                              MANNHEIMER SWARTLING

                                            Stockholm, December 19, 2002    6(9)
- --------------------------------------------------------------------------------

(h)   pursuant to the Swedish Contracts Act (Sw: Avtalslagen), the terms of an
      agreement may be modified or set aside by a court to the extent that such
      terms are deemed to create unreasonable results, even if the circumstances
      giving rise thereto have arisen after the agreement was entered into;

(i)   the term "enforceable" when used herein means that the obligations assumed
      by the parties are of the type which Swedish courts enforce. It does not
      mean that such obligations will necessarily be enforced in accordance with
      their terms. The availability of equitable remedies, including but not
      limited to injunction and specific performance, is restricted and such
      remedies may not always be granted by the court;

(j)   the taking of proceedings in other jurisdictions may preclude the taking
      of proceedings in Sweden, if the claims and the parties respectively in
      the proceedings are substantially identical; the availability of access to
      Swedish courts may be limited by the existence of a valid arbitration
      agreement or clause; the opening of insolvency proceedings in other
      jurisdictions pursuant to the EC Insolvency Regulation, may preclude the
      taking of proceedings in Sweden;

(k)   Swedish courts may award judgments in currencies other than Swedish
      Kronor, but a judgment will be enforced in Swedish Kronor. Enforcement in
      Sweden of such judgment would, if implemented in Swedish Kronor, be
      generally at the rate of exchange applicable at the date of enforcement
      rather than at the date of judgment; choice of currency provisions may not
      constitute a right to refuse payment in Swedish Kronor, and the creditor
      may have to rely on damages or contractual indemnities in case of breach
      of such provisions;

(l)   the enforcement of the rights of a party under an agreement may be limited
      by general time bar provisions or the doctrine of laches;

(m)   it is not established by law or court precedent that a power of attorney
      can be made irrevocable and it is therefore submitted that all powers of
      attorney contained in the Operative Documents can be revoked and that they
      will terminate by operation of law and without notice at the bankruptcy of
      the party giving such powers;

(n)   provisions in the Operative Documents specifying that provisions thereof
      may only be amended or waived in writing, may not be enforceable to the
      extent that an oral agreement or implied agreement by trade practice or
      course of conduct has been created modifying provisions of the Operative

                              MANNHEIMER SWARTLING

                                            Stockholm, December 19, 2002    7(9)
- --------------------------------------------------------------------------------

      Documents;

(o)   in proceedings before a Swedish Court, the Swedish Procedural Code will
      apply in respect of, inter alia, service of process, allocation of costs
      for the proceedings, availability of interim measures and evaluation of
      evidence; consequently provisions in the Operative Documents relating to
      such matters will not be enforceable to the extent inconsistent herewith.
      Specifically, without limiting the generality of the foregoing, a
      provision that a certain determination is conclusive and binding will not
      prevent judicial inquiry into the merits of any claim by the aggrieved
      party;

(p)   provisions in the Operative Documents to the effect that one party may
      terminate an agreement or otherwise act to the detriment of another party
      in the case of a bankruptcy of such other party could be considered
      contrary to the Swedish Bankruptcy Act (Sw: konkurslagen) and are, to the
      extent they are found to be so, unenforceable;

(q)   the right to recover damages may be limited to the extent the aggrieved
      party could have avoided damages by reasonable efforts;

(r)   on the basis of the International Monetary Fund Agreement, as interpreted
      and applied by Swedish courts, an obligation which is contrary to the
      exchange control regulations of another member state of the International
      Monetary Fund may not be enforceable in Sweden;

(s)   any transfer of rights, or payment in respect of, or other performance of,
      an obligation under any of the Operative Documents involving the
      government of any country which is currently the subject of United Nations
      or European Union sanctions, any person or body resident in, incorporated
      in or constituted under the laws of any such country or exercising public
      functions in any such country or any person or body controlled by any
      foregoing or by any person acting on behalf of any of the foregoing may be
      subject to restrictions pursuant to such sanctions as implemented in
      Swedish law;

(t)   this opinion is limited to matters of Swedish law as presently in force
      and as enacted by Swedish legislative authorities, and no opinion is
      expressed as to the laws of any other jurisdiction or supra-national
      organisation (such as the EU); in particular we do not represent ourselves
      to be familiar with the laws of the State of New York or the laws of any
      jurisdiction other than Sweden and we express no opinion in respect of
      matters governed by or construed in accordance with any such laws;

                              MANNHEIMER SWARTLING

                                            Stockholm, December 19, 2002    8(9)
- --------------------------------------------------------------------------------

(u)   this opinion is given on the basis that it will be governed by and
      construed in accordance with Swedish law; and

(v)   this opinion is strictly limited to matters stated herein and is not to be
      read as extending by implication to any other matters in connection with
      the Operative Documents.

                              --------------------

This opinion is addressed to its addressees for their own use and benefit and
for the use of their legal advisers (without assuming any liability in relation
to such advisers) and may not be relied upon by any other person or for any
purpose other than in connection with the Operative Documents and it is not to
be used, circulated, quoted or otherwise referred to for any other purpose,
except that we consent to the filing of this opinion as an exhibit to the
Registration Statement under the U.S. Securities Act of 1933, which was filed
with the U.S. Securities and Exchange Commission (the "SEC") on 13 November 2002
by the registrants WH Intermediate Holdings Ltd. and Herbalife International,
Inc. (Registration No. 333-101188), provided that our consent to such filing
shall not give the SEC or any other party any right to rely on the contents of
this opinion.

We assume no obligation to advise you or the SEC of any changes in the foregoing
subsequent to the date set forth in the beginning of this opinion and this
opinion speaks only as of that date.

Yours faithfully,
