promises and covenants contained herein, and other consideration (the receipt
and sufficiency of which is hereby acknowledged by both parties) Telemarketer

          ---------------------------------
Telemarketer under this Agreement shall consist of contacting by telephone those

of independent contractors.

     2.   TELEMARKETER RESPONSIBILITIES.  (a) The persons who shall make the
          -----------------------------
telephone presentations contemplated by this Agreement (such persons being
referred to hereinafter collectively as the "Representatives" and individually
as a "Representative") shall strictly adhere to the telephone scripts and
written materials furnished to the Telemarketer by Client from time to time for
use by such Representatives. The Representatives and Telemarketer shall strictly
observe any and all Standards of Conduct and Performance for each market which
shall be provided in writing to such Representatives and Telemarketer and which
may be amended from time to time. In the event any state or other governmental
authority requires that any Representative(s) be licensed or registered to sell
Client's product, Client shall inform Telemarketer in writing and thereafter
each Representative soliciting sales of Client's product in the affected
jurisdiction shall be licensed or registered in accordance with instructions
provided by Client. Any person who shall be licensed or registered as described
above shall for the purposes of this Agreement be referred to as a "Licensed
Representative."

          (b)  Telemarketer shall use its best efforts to assure that the
services provided under this Agreement are of the highest quality. In that
connection, Telemarketer shall implement and maintain an ongoing program of
observation and monitoring of telephone presentations and an ongoing
verification program for all enrollments in and purchases of products offered by
or through Client. In addition, Telemarketer shall provide Client with the names
and telephone numbers of persons who request that they not receive future
telephone calls made by or on behalf of Client. Client shall have the right to
have access from time to time to the offices of Telemarketer for the purpose of
performing on-site audits and inspections to ensure that Telemarketer and its
Representatives are discharging their respective obligations and duties under
this Agreement strictly in accordance with the terms, conditions and provisions
contained herein.

          (c)  Client shall have the right so often as it desires to monitor the
services performed by Telemarketer. Telemarketer, at its expense, shall install
in its offices appropriate equipment and provide reasonable facilities in its
offices so that Client or its designees may monitor the telephone presentations
from the offices of Telemarketer and from other locations.

          (d)  Telemarketer shall report on its activities and results to Client
or Client's designee, including daily operating results, by product, by
campaign, and by campaign month, on a schedule required by Client, and to make
such other reports available as may be requested by Client.

     3.   CONFIDENTIALITY.  (a)  It is understood that, in working on any of
          ----------------
the Client's projects, Telemarketer will come into possession of certain
proprietary information that belongs to Client or to a third party to which
Client is responsible for confidentiality. Such proprietary information
includes, but is not limited to, marketing practices, product features, scripts,
marketing records and reports, customer records, telephone call lists and
mailing lists. Telemarketer  agrees that it will not willfully or negligently
divulge any such information and may not under any circumstances divulge any
such information to third party without the prior written consent of Client.
Telemarketer further acknowledges that as between Client and

                                      -2-
<PAGE>

Telemarketer, all such information and records are the sole property of Client,
and Telemarketer shall acquire no rights whatsoever in or to them. Telemarketer
will institute such procedures and will cause the Representatives to execute
such written agreements as shall be necessary or appropriate to ensure that the
confidentiality of Client's proprietary information is strictly maintained. At
any time requested by Client, Telemarketer shall promptly transfer and deliver
to Client all such information and records in the manner and timeframe
designated by Client.

          (b)  The Telemarketer shall not, without first receiving written
permission from Client, in any manner, advertise, publish or use as reference
the fact that the Telemarketer has contracted to furnish to Client the services
specified herein. This contract is confidential, and the Telemarketer shall not
disclose the details hereof to any third party except to the extent required in
the performance hereof.

          (c)  It is further understood that neither party shall, during the
term of this Agreement and for two years thereafter, hire or recruit for hire
any person who is or has been within the preceding year an employee of the other
party, unless such party obtains the express written permission of the other
party.

          (d)  During the duration of this Agreement, Telemarketer agrees not to
solicit nor telemarket Bonus Products for any provider of membership or club
services besides Client within any of Telemarketer's calling centers and
locations or those of any telemarketer affiliated with Telemarketer where
Telemarketer conducts telemarketing for Client. Bonus Products are any club or
membership products where the customer receives full benefits of membership for
an initial period of time without being charged a fee or where the fee for the
initial period is paid by the sponsoring organization.  Telemarketer further
agrees that Client may audit any books and records of Telemarketer to verify
compliance with this provision.

          (e)  The obligations in sub-paragraphs 3(a) through 3(c) shall survive
any termination of this Agreement.

     4.   FEES AND PAYMENT TERMS.  (a)  Client shall pay Telemarketer an hourly
          ----------------------
rate as described in the attached Exhibit A, for each Representative Hour
worked. "Representative Hour" is defined as an hour of actual talk time, call
wrap up time, and normal wait time between calls each Representative spends
working on a campaign, and does not include non-productive time such as break
time, lunch time, system down time or training time, whether or not the
Representative is logged on the system during such time periods. A
Representative Hour also does not include time spent in verifying, confirming or
otherwise completing a sale by persons other than the Representative making the
telephone presentation. It is expressly understood and agreed that the only
compensation payable hereunder or for the services of Telemarketer shall be as
set forth in Exhibit A attached hereto and Client shall not in any manner
compensate Telemarketer on the basis of whether or to what extent the telephone
presentations result in the sale of any product of Client. Telemarketer
expressly warrants and agrees that Telemarketer will not pay any Representative
any compensation or commission on the basis of whether or to what extent the
telephone presentations made by a Representative result in the sale of any
product.

                                      -3-
<PAGE>

          (b)  Telemarketer shall submit to Client or its designee invoices not
more often than bi-weekly, itemized by product, by campaign, and by campaign
starting date. Such invoices shall be paid by Client no later than the 30th day
after receipt of the invoice by Client. Telemarketer understands and agrees that
once it submits an invoice to Client, it may not for any reason thereafter
increase the fees payable by Client for the period covered by the invoice.

          (c)  Telemarketer, recognizing the sensitivity and confidentiality of
information agrees that Client, at any reasonable time and place, and upon
reasonable notice, may audit the books and records of the Telemarketer, and
examine its employees, to verify compliance with the terms of this Agreement.
Furthermore, Client reserves the right to audit Telemarketer's telephone
records, licensing records, and other supporting information and records with
respect to the invoices. The relevant records will be maintained by Telemarketer
for two (2) years after invoicing pursuant to this Agreement.

     5.   COMPLIANCE WITH LAWS.  Telemarketer shall conduct its telemarketing
          --------------------
services on behalf of Client in accordance with all applicable federal, state
and local laws, as well as the Ethical Guidelines for Telemarketers published by
the Direct Marketing Association. Telemarketer will obtain and maintain any and
all licenses or permits required for the performance of the services
contemplated by this Agreement.  Telemarketer shall comply in all respects with
the record keeping requirements of the Telemarketing and Consumer Fraud and
Abuse Prevention Act and the rules promulgated thereunder. Specifically,
Telemarketer shall retain the legal name, any fictitious name used, last known
home address and telephone number and job title(s) for each Representative
engaged in telephone sales on behalf of Client. If Telemarketer permits its
Representatives to use fictitious names, each such fictitious name shall be
traceable to only one employee. Records concerning any employee shall be
retained for a period of 24 months from the last date such employee is engaged
in telephone sales activity on behalf of Client and such records shall be stored
by Telemarketer in a form, manner, format and place as Telemarketer usually
keeps records in the ordinary course of its business.

     6.   INDEMNITY AND LIABILITY.  Telemarketer agrees to defend, indemnify and
          -----------------------
hold harmless Client, its officers, directors, employees and affiliates from and
against any and all costs, liabilities, damages, judgments, penalties or fines,
including but not limited to reasonable attorney's fees, directly or indirectly
sustained or paid by Client or its affiliates, by suit, claim, settlement, or
otherwise in an individual or class action, by a private party or any agency of
any government, caused as a result of the breach of this Agreement, negligence
or willful misconduct of or by Telemarketer, its officers, directors, employees
or contractors. The obligations of this paragraph shall survive any termination
of this Agreement.

     7.   INSURANCE. Telemarketer shall maintain, during the term of this
          ---------
agreement, insurance coverage, including but not limited to, comprehensive
general liability insurance and worker's compensation insurance with aggregate
and per occurrence limits no lower than $1,000,000. Such insurance shall cover
all claims arising during the term of this Agreement whether or not brought
during such term and shall name Client as an additionally insured party.
Telemarketer shall furnish to Company upon request, certificates of such
insurance.

                                      -4-

covenant contained herein, Client shall have the right to terminate this
Agreement immediately by giving written notice of termination to Telemarketer at

     11.  ASSIGNMENT.  This Agreement may not be assigned by either party
          ----------

any part of the work being performed under this Agreement without the written
consent of Client.

     12.  MISCELLANEOUS.  This Agreement shall be construed in all respects
          -------------
