         UNDERWRITER                      TRANCHE A                TRANCHE B            TRANCHE C

         The commitment of each Underwriter is several and failure by one
Underwriter to perform its obligations hereunder shall not prejudice the rights
of any other Underwriter. Each Underwriter may, except as otherwise stated,
enforce its rights separately. No Underwriter shall be responsible for the
obligations of any other Underwriter.

         2.       CONDITIONS PRECEDENT. Each of the Arranger's respective
agreements and each of the Underwriter's respective commitments hereunder is
subject to: (i) the preparation, execution and delivery of mutually acceptable
loan documentation, including a credit agreement (the "CREDIT AGREEMENT")
incorporating, INTER ALIA, the terms and conditions outlined in the Terms and
Conditions (which set out the material commercial terms of the Credit
Agreement); (ii) in the Arrangers' and Underwriters' collective opinion, the
absence of a material adverse change in (A) the business, financial condition or
prospects of the Parent or the Parent and its subsidiaries taken as a whole
since 31 December 1999 and (B) the loan syndication, financial or capital market
conditions generally that, in the Arrangers' and Underwriters' collective
opinion, would materially impair syndication of the Facility; (iii) the accuracy
and completeness in all material respects of the factual information contained
in the package of written information provided to each of the Arrangers and
Underwriters and of all written factual information provided to the Arrangers
and Underwriters hereafter and your compliance with the terms of the Commitment
Documents; and (iv) the payment in full of all fees, expenses and other amounts
due and payable under the Fee Letters.

         3.       SYNDICATION.

                  3.1      The Arrangers and the Underwriters reserve the right
from 9 June 2000, such date being the "SYNDICATION DATE", until the earlier of
the date upon which the Arrangers and the Underwriters declare that syndication
has closed or 31 December 2000, such date being the "SYNDICATION CLOSING DATE",
to syndicate all or a portion of their commitment to one or more other financial
institutions (the financial institutions becoming parties to the Credit
Agreement being collectively referred to herein as the "LENDERS").

                  3.2      The Arrangers will act as arrangers with respect to
the Facility and will manage all aspects of the syndication in consultation with
you. You understand that the Arrangers intend to commence syndication efforts
promptly from the Syndication Date.


                                        2


                  3.3      You agree to take all action as the Arrangers and the
Underwriters may reasonably request to assist it in forming a syndicate
acceptable to it. Your assistance in forming such a syndicate shall include but
not be limited to: (i) making senior management and representatives of you
available to participate in information meetings with potential Lenders at such
times and places as may be mutually agreed; (ii) using your reasonable efforts
to ensure that the syndication efforts benefit from your lending relationships
and (iii) providing the Arrangers and the Underwriters with all information of a
type commonly provided or made available to successfully complete the
syndication of credit facilities including, without limitation, the preparation
of an Information Memorandum in respect of the Facility for distribution to
potential Lenders.

                  3.4      To ensure an orderly and effective syndication of the
Facility, you agree that until the Syndication Closing Date, you will not, and
will not permit any of your subsidiaries to, syndicate or issue, attempt to
syndicate or issue, announce or authorise the announcement of the syndication or
issuance of, or engage in discussions concerning the syndication or issuance of,
any debt facility (including the establishment of a series of bilateral
arrangements) or debt securities (including any renewals thereof) in the
commercial bank (or capital) markets other than:

                           (i)      the proposed Bridge Loan in an amount of
         Euro 1,050,000,000;

                           (ii)     the proposed Convertible Bond in an amount
         of approximately Euro 700,000,000 (being subordinated to the Facility
         and with a maturity greater than the Facility);

                           (iii)    the renewal of existing overdraft facilities
         (including in Rexall Sundown, Inc.);

                           (iv)     the existing Belgian commercial paper
         program; or

                           (v)      with the prior written consent of the
         Arrangers.

                  3.5      You agree that the Arrangers will act as the sole
arrangers for the Facility, that ING will act as Facility Agent and as
documentation agent and Deutsche Bank and SBIL will act as bookrunners and that
no additional arrangers, co-arrangers or agents will be appointed, or other
titles conferred, without the Arrangers' consent. You agree that no Lender will
receive any compensation of any kind for its participation in the Facility,
except as expressly provided for in the Fee Letter, the Agency Fee Letter or in
the Terms and Conditions.

                  3.6      The agreements of the Arrangers and Underwriters
hereunder and of any Lender that issues a commitment to provide financing under
the Facility are made solely for the benefit of you and may not be relied upon
by any other person.

         4.       MARKET CONDITIONS. You agree that, without prejudice to the
provisions hereof, the Arrangers and Underwriters have the right at any time
from the date of this Commitment Letter up to and including the Syndication
Closing Date to change the pricing and the tenor of the Facility if such change
is advisable in the judgment of the Arrangers and the Underwriters to ensure


                                        3


a successful syndication of the Facility (successful syndication being for these
purposes that each of the Underwriters as a result of such syndication, has
reduced its underwriting commitment to Euro 250,000,000 (or less)). If the
Arrangers and Underwriters determine that such changes are necessary, they will
consult with you for a period of up to 5 days about such changes.

         5.       COMMITMENT TERMINATION. Each Arranger's agreement and each
Underwriter's commitment set forth under paragraph 1 of this Commitment Letter
will terminate on (a) if the Offer is not extended, the earlier of the execution
of the Credit Agreement and 9 June 2000 and (b) if the Offer is extended, the
earlier of the execution of the Credit Agreement and 21 Business Days after 3
June 2000. Prior to such date, this Commitment Letter may be terminated (i) by
you at any time at your option after payment of all fees, expenses and other
amounts then payable under the Commitment Documents or (ii) by the Arrangers and
Underwriters if the Arrangers and Underwriters believe collectively that any
condition set forth in paragraph 2 can no longer be satisfied. The provisions of
the Fee Letter and paragraphs 3, 4, 6, 7 and 9 shall survive the expiration or
termination of this Commitment Letter.

         6.       INDEMNIFICATION.

                  6.1      Whether or not the Facility is consummated you hereby
indemnify and agree to hold harmless each Arranger, each Underwriter and each of
their affiliates and each of their respective officers, directors, employees,
agents, advisors and representatives (each, an "INDEMNIFIED PARTY") from and
against any and all claims, damages, losses, liabilities, costs and expenses
(including, without limitation, reasonable fees and disbursements of counsel),
joint or several, that may be incurred by or asserted or awarded against any
Indemnified Party by reason of that party acting in its capacity as an Arranger
or Underwriter (as the case may be), in each case arising out of or in
connection with or relating to any investigation, litigation or proceeding or
the preparation of any defence with respect thereto (each a "PROCEEDING"),
arising out of or in connection with or relating to the Commitment Documents,
whether or not such investigation, litigation or proceeding is brought by you,
any of your shareholders or creditors, an Indemnified Party or any other person,
or an Indemnified Party is otherwise a party thereto, except to the extent such
claim, damage, loss, liability, cost or expense results from such Indemnified
Party's negligence, wilful misconduct or any breach of the Commitment Documents
by the Indemnified Party.

                  6.2      Any Indemnified Party intending to invoke paragraph
1.1 shall give prompt notice in writing to you upon it becoming aware of any
actual or potential claim, damage, loss, cost or expense, and you shall
thereafter be entitled to be joined as party in any proceeding and/or to give
directions to the relevant Indemnified Party in relation to the conduct of such
proceeding PROVIDED THAT (i) you give prompt notice in writing of your intention
to give such directions to the Indemnified Party, (ii) you give such directions
taking into account at all times the business sensitivities and franchise
position of the Indemnified Party and (iii) you do not give directions in
respect of regulatory or supervisory proceedings of any governmental authority
or other similar proceedings.

                  6.3      No Indemnified Party shall settle, compromise,
consent to the entry of any judgement in or otherwise seek to terminate (each a
"SETTLEMENT") any such proceeding without your


                                        4


prior written consent (such consent not to be unreasonably withheld or delayed,
taking into account without limitation the cost to you and that Indemnified
Party of continuing, the likely outcome of that proceeding and the adverse
effects (actual or potential) on the business interests and/or reputation of you
and that Indemnified Party of not settling). You shall not be liable to
indemnify any Indemnified Party for any settlement of any proceeding made or
effected without your prior written consent.

                  6.4      You will lose your right to give directions in
relation to any proceedings if (i) you breach any obligations hereunder or (ii)
at the written request of the Indemnified Party, and in respect of (ii) your
obligation to indemnify the Indemnified Party will cease on the date of such
request.

                  6.5      You further agree that no Indemnified Party shall
have any liability (whether direct or indirect, in contract, tort or otherwise)
to you or any of your shareholders or creditors for or in connection with the
transactions referred to above, except to the extent such liability results from
such Indemnified Party's negligence, wilful misconduct or any breach of the
Commitment Documents by the Indemnified Party.

                  6.6      The Contracts (Rights of Third Parties) Act 1999
shall only apply to this paragraph 6 and only for the benefit of the Indemnified
Parties.

         7.       CONFIDENTIALITY.

                  7.1      You agree that the Commitment Documents are for your
confidential use only and that neither their existence nor the terms thereof
will be disclosed by you to any person other than your officers, directors,
employees, accountants, lawyers and other advisors, or those parties (and their
officers, directors, employees, accountants, lawyers and other advisors)
involved in the Project Planet negotiations, and then only on a "need to know"
basis in connection with the transactions contemplated thereby and on a
confidential basis. Notwithstanding the foregoing, following your return of your
executed copies of the Commitment Documents to the Facility Agent as provided
below, you may make such other public disclosures of the terms and conditions
hereof as (i) you are required by applicable law or regulation (whether of the
Amsterdam Stock Exchange or otherwise) to make; (ii) are otherwise publicly
available; or (iii) are necessary to maintain your rights under the Commitment
Documents.

                  7.2      You should be aware that each Arranger and/or each
Underwriter may be providing financing or other services to parties whose
interests may conflict with yours. Be assured, however, that consistent with
each Arranger's and each Underwriter's longstanding policy to hold in confidence
the affairs of its customers, no Arranger nor any Underwriter will furnish
confidential information obtained from you to any of its other customers. By the
same token, none of the Arrangers nor any Underwriter will make available to you
confidential information that it obtained or may obtain from any other customer.

         8.       REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  You
represent and warrant to each Arranger and each Underwriter that (i) all written
information provided


                                        5


to each Arranger and each Underwriter, and any further written information
provided to each Arranger and each Underwriter after the date hereof by you or
your representatives in connection with the transactions contemplated hereby is
and will be complete and correct in all material respects and does not and will
not contain any untrue statement of a material fact or omit to state a material
fact necessary in order to make the statements contained therein not misleading
in light of the circumstances under which such statements were or are made, (ii)
all financial projections, (if any), that have been or will be prepared by the
Arrangers or the Underwriters and approved by the Parent are based upon
assumptions considered by you to be reasonable (it being understood that such
projections are subject to significant uncertainties and contingencies, many of
which are beyond your control, and that no assurance can be given that the
projections will be realised) and (iii) you are not in possession of any
information which would result in you concluding that the latest published
financial statements of Rexall Sundown Inc. are not true and accurate in any
material respect. You agree, as close as is reasonably practicable to the
Syndication Closing Date, to supplement the information and projections from
time to time so that the representations and warranties contained in this
paragraph remain correct.

         9.       GOVERNING LAW/JURISDICTION. The Commitment Documents shall be
governed by, and construed in accordance with, the laws of England and Wales.
The parties hereto submit to the non-exclusive jurisdiction of the English court
and waive any defence of inconvenient forum which may be available.

         10.      ENTIRE AGREEMENT. The Commitment Documents set forth the
entire agreement between the parties with respect to the matters addressed
therein and supersede all prior communications, written or oral, with respect
thereto and may only be modified in writing. Delivery of an executed signature
page to any Commitment Document by facsimile shall be as effective as delivery
of a manually executed document.

         Please indicate your acceptance of the provisions hereof by signing the
enclosed copy of this Commitment Letter, the Fee Letter and the Agency Fee
Letter and returning them to Digna Hiel at ING Bank N.V. at or before 5:00 p.m.
(London time) on 31 May 2000, the time at which the commitment offer of each
Underwriter set forth above (if not so accepted prior thereto) will expire. If
you elect to deliver the above documents by facsimile, please arrange for the
executed originals to follow by next-day courier.

                                         Yours faithfully,

DEUTSCHE BANK AG                         ING BANK N.V.
