Woodbury, NY 11797

Dear Sirs:

            This letter serves to confirm the retention of The Invus Group, Ltd.
("Invus") by Weight Watchers International, Inc. (the "Company") to provide
management, consulting and financial services to the Company and to its
divisions, subsidiaries and affiliates (collectively, "WW"), as follows:

            1. The Company has retained Invus, and Invus hereby agrees to accept
such retention, to provide to WW, when and if called upon, certain management,
business strategy, consulting and financial services of the type customarily
performed by us. The Company agrees to pay us an aggregate annual fee equal to
the greater of (i) one million dollars ($1,000,000) and (ii) 1.0% of the
Company's EBITDA (as defined in the Company's Offering Circular, dated September
22, 1999), payable in quarterly installments in arrears at the end of each
calendar quarter, commencing on December 31, 1999 (the fee for the period from
the date hereof until December 31, 1999 being pro rated based on the
number of days elapsed from September 29, 1999 through December 31, 1999);
provided Invus may elect, at any time or

                                                                               2


from time to time, to defer the payment to it of such fee and such deferred
payment (and any other payments not made when due hereunder) shall accrue
interest at a rate of 6% per annum until paid in full. Any such deferred payment
shall be payable upon demand of Invus. From time to time after the date hereof,
we may notify the Company in writing of a different amount of such annual fee
for any particular year or for subsequent years, and, in such event, from and
after such notification, such annual fee shall be the annual fee.

            If any other entity owned by our affiliates on the date hereof shall
be combined with the Company after the date hereof, then we agree that we will
terminate any requirement for such other entity to pay an annual fee for
services of the type referred to in this paragraph 1.

            2. We may also invoice the Company for additional investment banking
fees in connection with acquisition, divestiture or certain other transactions
or in the event that we or any of our affiliates, performs services for WW above
and beyond those called for by this agreement.

            3. In addition to any fees that may be payable to us under this
agreement, the Company also agrees to reimburse us and our affiliates, from time
to time upon request, for all reasonable out-of-pocket expenses incurred,
including unreimbursed expenses incurred to the date hereof, in connection with
this retention, including travel expenses and expenses of our counsel.


                                                                               3


            4. The Company agrees to indemnify and hold us and our affiliates,
partners, executives, officers, directors, employees, agents and controlling
persons (each such person, including Invus, respectively, being an "Indemnified
Party") harmless from and against any and all losses, claims, damages and
liabilities (including, without limitation, losses, claims, damages and
liabilities arising from or in connection with legal actions brought by or on
behalf of the holders or future holders of the outstanding securities of WW or
creditors or future creditors of WW), joint, several or otherwise, to which such
Indemnified Party may become subject under any applicable federal or state law,
or otherwise, related to or arising out of any activity contemplated by this
agreement or the retention of us pursuant to, and our or our affiliates'
performance of the services contemplated by, this agreement and will reimburse
any Indemnified Party for all expenses (including counsel fees and
disbursements) upon request as they are incurred in connection with the
investigation of, preparation for or defense of any pending or threatened claim
or any action or proceeding arising therefrom, whether or not such Indemnified
Party is a party and whether or not such claim, action or proceeding is
initiated or brought by the Company and/or WW; provided, however, that the
Company will not be liable to an Indemnified Party under the foregoing
indemnification provision (and amounts previously paid that are determined not
required to be paid by the Company pursuant to the terms of this


                                                                               4


paragraph shall be repaid promptly) to the extent that any loss, claim, damage,
liability or expense is found in a final judgment by a court to have resulted
from the willful misconduct, bad faith or gross negligence of such Indemnified
Party. The Company also agrees that no Indemnified Party shall have any
liability (whether direct or indirect, in contract or tort or otherwise) to WW
related to or arising out of the retention of Invus pursuant to, or the
performance by affiliates of Invus, of the services contemplated by, this
agreement except to the extent that any loss, claim, damage, liability or
expense is found in a final, non-appealable judgment by a court to have resulted
from the willful misconduct, bad faith or gross negligence of Invus.

            The Company also agrees that, without our prior written consent, the
Company and WW will not settle, compromise or consent to the entry of any
judgment in any pending or threatened claim, action or proceeding to which an
Indemnified Party is an actual or potential party and in respect of which
indemnification could be sought under the indemnification provision in the
immediately preceding paragraph, unless such settlement, compromise or consent
includes an unconditional release of each Indemnified Party from all liability
arising out of such claim, action or proceeding.

            Promptly after receipt by an Indemnified Party of notice of any
suit, action, proceeding or investigation with respect to which an Indemnified
Party may be entitled to indemnification


                                                                               5


hereunder, such Indemnified Party will notify the Company in writing of the
assertion of such claim or the commencement of such suit, action, proceeding or
investigation, but the failure so to notify the Company shall not relieve the
Company from any liability which it may have hereunder, except to the extent
that such failure has materially prejudiced the Company. If the Company so
elects within a reasonable time after receipt of such notice, the Company may
participate at its own expense in the defense of such suit, action, proceeding
or investigation. Each Indemnified Party may employ separate counsel to
represent it or defend it in any such suit, action, proceeding or investigation
in which it may become involved or is named as a defendant; provided, however,
that the Company will not be required in connection with any such suit, action,
proceeding or investigation, or separate but substantially similar actions
arising out of the same general allegations or circumstances, to pay the fees
and disbursements of more than one separate counsel (other than local counsel)
for all Indemnified Parties in any single action or proceeding. Whether or not
the Company participates in the defense of any claim, both the Company and Invus
shall cooperate in the defense thereof and shall furnish such records,
information and testimony, and attend such conferences, discovery proceedings,
hearing, trial and appeals, as may be reasonably requested in connection
therewith.

                                                                               6


            If the indemnification provided for hereunder is finally judicially
determined by a court of competent jurisdiction to be unavailable to an
Indemnified Party, or insufficient to hold any Indemnified Party harmless, in
respect of any losses, claims, damages or liabilities (other than any losses,
claims, damages or liabilities found in a final judgment by a court to have
resulted from the willful misconduct, bad faith or gross negligence of Invus),
then the Company, on the one hand, in lieu of indemnifying such Indemnified
Party, and Invus, on the other hand, will contribute to the amount paid or
payable by such Indemnified Party as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received, or sought to be received, by WW, on the one hand, and Invus,
solely in its capacity as advisor under this agreement, on the other hand, in
connection with the transactions to which such indemnification, contribution or
reimbursement is sought, or (ii) if (but only if) the allocation provided by
clause (i) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
but also the relative fault of WW, on the one hand, and Invus, on the other
hand, as well as any other relevant equitable considerations; provided, however,
that in no event shall our aggregate contribution hereunder exceed the amount of
fees actually received by us, in respect of the advice, opinion or transaction
at issue pursuant to this agreement.


                                                                               7


The amount paid or payable by a party as a result of the losses, claims, damages
and liabilities referred to above will be deemed to include any legal or other
fees or expenses reasonably incurred in defending any action or claim. The
Company and Invus agree, severally and not jointly, that it would not be just
and equitable if contribution pursuant to this paragraph were determined by pro
rata allocation or by any other method which does not take into account the
equitable considerations referred to in this paragraph. The indemnity,
contribution and expenses reimbursement obligations the Company has under this
paragraph shall be in addition to any liability the Company or WW may have, and
notwithstanding any other provision of this letter, shall survive the
termination of this agreement.

            5. Any advice or opinions provided by Invus may not be disclosed or
referred to publicly or to any third party (other than WW's legal, tax,
financial or other advisors), except in accordance with our prior written
consent.

            6. We shall act as independent contractors. The provisions hereof
shall inure to the benefit of and shall be binding upon the parties hereto and
their respective successors and assigns. Nothing in this agreement, expressed or
implied, is intended to confer on any person other than the parties hereto or
their respective successors and assigns, and, to the extent expressly set forth
herein, the Indemnified Parties, any rights or remedies under


                                                                               8


or by reason of this agreement. Without limiting the generality of the
foregoing, the parties acknowledge that nothing in this agreement, expressed or
implied, is intended to confer on any present or future holders of any
securities of the Company or its subsidiaries or affiliates, or any present or
future creditor of the Company or its subsidiaries or affiliates, any rights or
remedies under or by reason of this agreement or any performance hereunder.

            7. This agreement shall be governed by, and construed and
interpreted in accordance with, the law of the State of New York.

            8. The terms of this agreement are effective as of September 29,
1999. Except as otherwise provided herein, this agreement may be amended only
with the consent of the parties hereto. This agreement may be terminated by
Invus at any time.

            9. Each party hereto represents and warrants that the execution and
delivery of this agreement by such party has been duly authorized by all
necessary action of such party.

            10. If any term or provision of this agreement or the application
thereof shall, in any jurisdiction and to any extent, be invalid and
unenforceable, such term or provision shall be ineffective, as to such
jurisdiction, solely to the extent of such invalidity or unenforceability
without rendering invalid or unenforceable any remaining terms or provisions
hereof or affecting the validity or enforceability of such term or provision in
any other jurisdiction. To the extent permitted by applicable law, the parties

                                                                               9


hereto waive any provision of law that renders any term or provision of this
agreement invalid or unenforceable in any respect.

            11. Each of WW and Invus waives all right to trial by jury in any
action, proceeding or counterclaim (whether based upon contract, tort or
otherwise) related to or arising out of the retention of Invus pursuant to, or
the performance by Invus, or their respective affiliates, of the services
contemplated by this agreement.

            12. It is expressly understood that the foregoing paragraphs 2
through 5, 7, 11 and 12 in their entirety survive any termination of this
agreement.


                                                                              10


            If the foregoing sets forth the understanding among us, please so
indicate on the enclosed signed copy of this letter in the space provided
therefor and returning it to us, whereupon this letter shall constitute a
binding agreement among us.

                                        Very truly yours,

                                        THE INVUS GROUP, LTD.
