                          CO-BRANDED SERVICE AGREEMENT

     This Agreement, dated as of December 14, 1999 (the "Effective Date"), is
made by and between Quepasa.com, Inc., a Nevada corporation with its principal
place of business at 400 East Van Buren, Phoenix, AZ 85004 ("QuePasa"), and
NetZero, Inc., a Delaware corporation with its principal place of business at
2555 Townsgate Road, Westlake Village, CA 91361 ("NetZero").

                                    Recitals
                                    --------

     WHEREAS QuePasa is the owner or licensee of certain Web properties and
services targeting the U.S. Hispanic community in both the English and Spanish
language, including Internet Web sites and online communities (collectively, the
"QuePasa Services");

     WHEREAS NetZero provides free dial-up Internet access services in the
United States of America in the English language (the "NetZero Service") to its
subscribers. In conjunction with the NetZero Service, a persistent window ("The
ZeroPort") is displayed to subscribers while connected to the NetZero Service;
and

     WHEREAS the parties would like to offer free dial-up Internet access
services and content targeted to the U.S. Hispanic community through a
customized version of the NetZero Service and The ZeroPort utilizing the QuePasa
Services, including a co-branded start page in both the Spanish and English
language (the "Customized NetZero Service"). It is understood that the
Customized NetZero Service is intended to be designed primarily for bilingual
consumers.

     NOW, THEREFORE, QuePasa and NetZero hereby agree as follows:

     1. The Co-branded Start Page.

     a. Development of the Co-branded Start Page. QuePasa and NetZero shall
jointly design and create a co-branded Web start page (the "Co-branded Start
Page") to be used in connection with the Customized NetZero Service (as defined
in Section 2(a)). The Co-branded Start Page shall be based upon both the home
page for the web site located at www.quepasa.com and NetZero specifications for
co-branding such page with the NetZero trademarks, logos, and links as mutually
agreed upon. The Co-branded Start Page shall be subject to final approval by
NetZero, which approval will not be unreasonably withheld. QuePasa shall, at no
cost to NetZero, develop, implement and manage the Co-branded Start Page.
Without limiting the generality of the foregoing, the Co-branded Start Page
shall be created, designed and developed pursuant to the following provisions:

                    (i) QuePasa Content. The Co-branded Start Page shall include
            the full spectrum of QuePasa content, consumer applications and
            services. In addition, the co-branded start page may include links
            to other areas of sites owned or controlled by QuePasa (such sites,
            the "QuePasa Sites") and links to
   2
     other sites owned or controlled by third parties. QuePasa shall use best
     efforts to monitor and prevent offensive, pornographic or hate content from
     being displayed to Subscribers.

          ii.  NetZero Content. In addition, the Co-branded Start Page shall
include: (A) links and graphics to NetZero services including, without
limitation, customer service, technical support, and member benefits, and (B)
content, buttons or other editorial product selected by NetZero, provided,
that, such content, buttons or other editorial product shall not exceed 12 1/2%
of the "above the fold" real estate of the Co-branded Start Page when displayed
at full height on an 800x600 pixel resolution screen.

     b. Advertising. QuePasa will be responsible for and receive all revenues
from all advertising related activities on all of the pages on the Co-branded
Start Page and QuePasa Sites provided, however, that in no event shall QuePasa
display advertising on the Co-branded Start Page or on the QuePasa Sites for
free internet access services which compete directly with the NetZero Service
or the Customized NetZero Service.

     c. Hosting. QuePasa shall maintain, operate, host and serve, at no cost to
NetZero, the Co-branded Start Page and the QuePasa Sites. The URL of the
Co-branded Start Page will be substantially similar to "www.netzero.quepasa.com"
or as otherwise mutually agreed upon by the parties.

     d. Exclusivity. During the Term, QuePasa shall not enter into any
relationships for a co-branded site, co-branded service or co-branded start page
with any free internet access service providers which compete directly with the
NetZero Service or Customized NetZero Service in the United States, provided
that if QuePasa is in a relationship for a co-branded site, co-branded service
or co-branded start page with a partner that becomes a free internet access
provider which competes directly with the NetZero Service or Customized NetZero
Service during the Term, QuePasa shall be allowed to maintain such relationship
so long as QuePasa does not advertise or promote such free internet access
service on the Co-Branded Start Page or on the QuePasa Sites.

          2. Customized NetZero Service. NetZero and QuePasa shall cooperate in
the development of the Customized NetZero Service as set forth in this Section
2.

     a. Customized NetZero Service. NetZero shall allow each of its subscribers
to elect to receive the Customized NetZero Service. As part of the Customized
NetZero Service, NetZero shall provide customer support and documentation in
the Spanish language for its subscribers that elect to receive the Customized
NetZero Service ("Subscribers") in a manner similar to customer support and
documentation provided for subscribers to the NetZero Service.

               i. Registration Process. Subscribers may elect to use the
Customized NetZero Service through a process to be developed and implemented by
NetZero. NetZero will use commercially reasonable efforts to consult with, and
obtain feedback from, QuePasa with respect to such process.

                                       2
   3
     The Subscriber default start page shall be dependent upon the Subscriber's
     election to receive content targeted to the U.S. Hispanic community through
     a customized version of the NetZero Service. NetZero subscribers will be
     sent an e-mail prior to the anticipated Launch Date informing such
     subscribers of the option to receive the Customized NetZero Service after
     the Launch Date.

                    ii.  Customized NetZero Service Implementation.  NetZero
     will use commercially reasonable efforts to implement the Customized
     NetZero Service, including the Customized ZeroPort (as defined in Section
     2(b) below) within ninety (90) days of the execution of this Agreement.
     Within thirty (30) days of the Effective Date, the parties shall develop a
     detailed implementation schedule for the Customized NetZero Service and the
     Customized ZeroPort (the "Implementation Plan").

    b. Customized ZeroPort.  As part of the Customized NetZero Service, NetZero
shall, at no cost to QuePasa, develop a customized version of The ZeroPort (the
"Customized ZeroPort") as more fully set forth below pursuant to the
Implementation Plan:

                    i.   NetZero shall configure the Customized ZeroPort so
     that the Co-branded Start Page will be the default and only start page for
     all Subscribers when such Subscriber uses the Customized NetZero Service.

                    ii.  The Customized ZeroPort shall contain a start button
     (the "Start Button") and search button ("Search Button") which link to the
     Co-branded Start Page and the applicable area of the QuePasa Sites,
     respectively.

                    iii. It is anticipated that the Customized ZeroPort will
     contain news, sports or weather buttons which shall be linked either to the
     applicable area of the Co-branded Start Page, other QuePasa Sites, or to
     third parties' Web sites, provided, that such third party Web site is not
     one of the ten exclusive URL's set forth in Exhibit B and all subdomains
     thereof and that the primary purpose of such third party web site is the
     provision of the applicable content.

                    iv.  NetZero shall make the applicable software for the
     Customized ZeroPort and Customized NetZero Service available in Spanish on
     a download page similar to the download page for the NetZero Service.

    c. Translation.  Pursuant to the Implementation Plan, the Customized
NetZero service will be translated into the Spanish language by NetZero and
QuePasa shall provide reasonable market specific modification and language
translation assistance, if any, with respect to the translation of the
Customized NetZero Service to the Spanish language.

    d. Advertising.  NetZero will be responsible for all advertising related
activities on the Customized NetZero Service, including the Customized ZeroPort.

                                       3
   4
     e.   Hosting. NetZero shall maintain, operate, host and serve at no cost
to QuePasa, the Customized NetZero Service.

     f.   Exclusivity. During the Term, NetZero shall not enter into any
relationships for a co-branded site, co-branded service or co-branded start page
targeting the U.S. Hispanic community with any other portal or content
aggregator which competes directly with the QuePasa Services.

          3.   Co-Marketing; Cooperation.

     a.   Marketing Plan. The parties shall develop a mutually agreeable
marketing plan for the services contemplated hereunder within ninety (90) days
after the Effective Date. At a minimum, the marketing plan shall include the
following: (i) the parties shall feature the Customized NetZero Service in a
portion of the parties' respective marketing and promotional campaigns; (ii) all
standard marketing and promotional CD's produced after a mutually agreed upon
date and distributed by NetZero that are not co-branded with a third party shall
contain the applicable software for the Customized NetZero Service; (iii)
QuePasa shall commit to spend at least one million dollars ($1,000,000), and if
the aggregate amount payable for Logon Fees and Referral Fees payable hereunder
as set forth in Section 4(a) exceeds $6,000,000, QuePasa shall commit to
spending an additional one million dollars ($1,000,000), for the production and
distribution of CD's containing the Customized NetZero Service and other
mutually agreeable content, and QuePasa shall have exclusive control over
ordering or initiating the production and distribution of such CD's; provided,
that the amounts paid by QuePasa hereunder to produce and distribute such CD's
shall not exceed NetZero's reasonable costs of production and distribution of
the CD's; provided further, that such amounts will not be due and payable by
QuePasa until QuePasa places orders for such CD's and then only in the amount of
such orders; and (iv) QuePasa will use reasonable efforts to secure the rights
to bundle the NetZero software on Gloria Estefan music CD's; provided, however,
that QuePasa shall not be obligated to pay for any such rights.

     b.   Banner Advertising. NetZero shall provide to QuePasa, at no charge,
three eights of one percent (0.375%) of NetZero's total inventory of banner
advertising impressions on the Customized ZeroPort. NetZero shall provide URL
targeted banner advertising impressions for fifteen (15) URL's as mutually
agreed upon by the parties as set forth in Exhibit A attached hereto. URL
targeted banner advertising impressions means banner advertising impressions
that are displayed in the Customized ZeroPort when a Subscriber visits the
targeted URL. The parties shall mutually agree upon the ten of such URL's that
will be provided to QuePasa on an exclusive basis (meaning that a QuePasa URL
targeted banner advertising impression will be the first URL targeted banner
advertising impression that will be displayed in the Customized ZeroPort for
the exclusive URL's) and the five of such URL's that will be provided to
QuePasa on a non-exclusive basis. For such non-exclusive URL's, no more than
three other advertisers will be assigned to each URL for rotation (meaning that
a QuePasa URL targeted banner advertising impression will be the first URL
targeted banner advertising impression that will be displayed in the Customized
ZeroPort on an average of every fourth URL targeted banner advertising
impression displayed for the non-exclusive URL's). QuePasa shall be


                                       4
   5
provided a defense shield for the QuePasa Sites, meaning that no direct
competitor to QuePasa may target the QuePasa Sites with URL targeted banner
advertising. QuePasa will receive, at no charge, targeted keyword banner
advertising impressions for twenty (20) mutually agreed upon keywords as set
forth in Exhibit B attached hereto. Targeted keyword banner advertising
impressions means banner advertising impressions that are displayed in the
Customized ZeroPort when a user types the applicable keyword into a browser or
search engine supported by NetZero. Five (5) of such keywords shall be provided
to QuePasa on an exclusive basis as mutually agreed upon by the parties
(meaning that a QuePasa keyword targeted banner advertising impression will be
the first keyword targeted banner advertising impression that will be displayed
in the Customized ZeroPort for the exclusive keywords). Exhibits A and B may
be updated with mutually agreeable URL's and keywords, respectively, once every
thirty days. QuePasa may not resell any of the banner advertising impressions
set forth hereunder.

     c. Reciprocal Links. As soon as practicable after the Effective Date,
QuePasa shall create a hyperlink above the fold on the QuePasa Site home page
located at www.quepasa.com to the NetZero Web site download page or such other
Web site as may be designated by NetZero; provided, that all users originating
from such hyperlink and who download the Customized NetZero Service will
automatically receive the Co-branded Start Page as their default start page.
QuePasa may move such link to any other QuePasa Site homepage, provided, that
such hyperlink shall at all times be displayed above the fold on the home page
of the primary QuePasa Site. As soon as practicable after the Effective Date,
NetZero shall create a hyperlink above the fold on the NetZero Web Site partner
page to the QuePasa Site home page.

     d. Teams. Each party shall designate a team responsible for furthering the
purpose of this Agreement, and such team shall consist of such party's
applicable personnel in the areas of business development, editorial,
marketing, sales, technology, legal and other areas that are relevant to this
Agreement.

     4.   Payments

     a. Logons and Referrals. QuePasa shall pay to NetZero a fee of ten cents
($0.10) each time the Co-branded Start Page is displayed to a Subscriber when a
Subscriber logs on to the Customized NetZero Service ("Logon Fee"). In addition,
QuePasa shall pay to NetZero a fee of five cents ($0.05) if a Subscriber visits
the Co-branded Start Page or any of the QuePasa Sites by using any of the
buttons on the Customized ZeroPart, including without limitation, the Search
Button and Start Button, or clicking through from the banner advertising
impressions provided hereunder (the "Referral Fee"), provided, that the Referral
Fee shall be payable only once per session of use of the Customized NetZero
Service by such Subscriber. If the aggregate amount payable for Logon Fees and
Referral Fees hereunder exceeds $6,000,000 and QuePasa has spent at least
$2,000,000 for the production and distribution of CD's as set forth hereunder,
the Logon Fee and Referral Fee for all subsequent transactions after the first
date on which both such aggregate amount payable exceeds $6,000,000 and QuePasa
has spent such $2,000,000, as applicable, shall be reduced to nine cents ($0.09)
and four and one-half cents ($0.045), respectively.

                                       5
   6
     b.   Reporting.     Following the Launch Date (as defined in Section 8),
NetZero shall track each logon and visit giving rise to a Logon Fee or Referral
Fee, respectively, and shall provide reports to QuePasa within ten (10) days
after the end of each month setting forth the number of transactions occurring
during prior month and the amounts due for such month.

     c.   Payments.

               i.   QuePasa shall make advance payments as set forth herein
     ("Advance Payments") which shall be deemed recoupable advance payments
     against amounts due and payable under Section 4(a). Within thirty (30) days
     of the execution of this Agreement, QuePasa will pay to NetZero an Advance
     Payment of one million dollars ($1,000,000). On the dates in each full
     calendar month thereafter which are three business days following QuePasa's
     receipt of the report discussed in Section 4(b) above, QuePasa shall pay
     to NetZero an Advance Payment of the applicable amount, if necessary, such
     that the then current Advance Balance (as defined in Section 4(c)ii) (as
     adjusted to include the applicable Advance Payment) is equal to the prior
     month's total Logon Fees and Referral Fees paid to NetZero plus twenty five
     percent (25%).

               ii.  Upon the provision of the report set forth in Section 4(b),
     NetZero shall deduct the applicable amount set forth in such report from
     the Advance Balance. If the Advance Balance is not sufficient to cover the
     entire amount due, QuePasa shall pay such remaining amount within fifteen
     (15) days upon written notice of such shortfall. "Advance Balance" shall
     mean the balance of the amount held by NetZero as the recoupable advance
     payment as increased by Advance Payments and decreased by applicable
     amounts due NetZero, provided, that the Advance Balance shall never be less
     than $0. For the purpose of example only, if at the end of the first month
     following the Launch Date, the total Logon Fees and Referral Fees payable
     are $200,000, then such amount shall be deducted from the Advance Balance,
     and the Advnce Balance shall be reduced to $800,000. The Advance Balance
     for the second month following the Launch Date is required to be $250,000
     ($200,000 + 25%), and because the Advance Balance is $800,000, QuePasa does
     not need to make an Advance Payment for such month.

     5.   Auditing. NetZero shall keep, maintain and preserve for at least two
(2) years following termination or expiration of the Term, accurate records
relating to the applicable transactions and fees hereunder. During the Term and
the six (6) month period following expiration or termination of the Term,
QuePasa shall have the right, at its expense, to audit such records of NetZero
for the purpose of verifying NetZero's reports and fees. Should any audit reveal
a greater than five percent (5%) overpayment by QuePasa for the period being
audited, NetZero shall reimburse QuePasa for all costs associated with such
audit in addition to all other amounts due to QuePasa. Audits shall be made upon
not less than five (5) days' prior written notice and during regular business
hours. NetZero shall promptly remit to QuePasa any overpayment amounts.

                                       6
   7
     6.   Aggregated and Individual Data. As mutually agreed to by the parties,
NetZero shall provide to QuePasa aggregated Subscriber data. Additionally,
NetZero shall provide to Subscribers the option to automatically register with
QuePasa for the customization of the Co-branded Start Page and if the
Subscriber elects such option, NetZero shall provide the applicable individual
Subscriber information to QuePasa. QuePasa may use such mutually agreed upon
individual data during the Term to individually customize the Co-branded Start
Page. QuePasa may use such aggregated data to better target and develop
content, e-commerce and advertising opportunities. QuePasa agrees that such
data is proprietary to NetZero and in no event shall QuePasa disclose, analyze,
compile, sell or otherwise use such data for any other purpose. Furthermore,
NetZero's obligation to provide such data and QuePasa's use of such data shall
be subject in all respects to, and shall comply with, all current and future
applicable laws, rules, regulations and orders regarding the collection,
retention, use, dissemination and confidentiality of such data, and to all
current and future policies and procedures of NetZero regarding the same.

     7.   Ownership. NetZero acknowledges and agrees that, as between QuePasa
and NetZero, QuePasa owns all title to, and all ownership rights in, any
QuePasa intellectual property, the QuePasa Sites and all proprietary aspects of
the Co-branded Start Page which are solely created and/or contributed by
QuePasa, including without limitation the underlying software but excluding any
NetZero brand features which are the sole property of NetZero. QuePasa
acknowledges and agrees that, as between QuePasa and NetZero, NetZero owns all
title to, and all ownership rights in, the Customized NetZero Service, the
Customized ZeroPort (including all software related to the Customized
ZeroPort)), any NetZero trademarks and all proprietary aspects of the
Co-branded Start Page which are solely created and/or contributed by NetZero,
including without limitation the underlying software but excluding any QuePasa
brand features which are the sole property of QuePasa. All Subscriber
information provided by a Subscriber to NetZero is owned by NetZero, including
Subscriber information passed to QuePasa as set forth in Section 6. All
Subscriber information provided by a Subscriber to QuePasa is owned by QuePasa.
QuePasa shall have the right to use all Subscriber information passed by NetZero
to QuePasa pursuant to Section 6 as set forth in Section 6.

Term, the parties shall negotiate in good faith the continuation of the
relationship hereunder and the terms and conditions of such relationship. If

not remedied within thirty (30) days of receipt of notice of such degradation
of service; or (vii) by mutual consent of the parties.

     b. NetZero may terminate this Agreement upon 10 days' written notice on
any Change of Control of QuePasa in which the successor or acquirer is

(50%) of the total combined voting power of QuePasa's outstanding securities
are transferred or issued, directly or indirectly, to any person or persons who

delinquency.

other party. Upon request of either party, the other party shall provide
appropriate attribution of the use of the requesting party's marks. All

from and against any and all third party claims, damages, liabilities, costs and
expenses, including reasonable legal fees and expenses, arising out of or

fees and expenses, against the Indemnified Party.

    a. Non-Disclosure Agreement. The parties agree and acknowledge that, as a
result of negotiating, entering into and performing this Agreement, each party
has and will have access to certain of the other party's Confidential
Information (as defined below). Each party also understands and agrees that
misuse and/or disclosure of that information could adversely affect the other
party's business. Accordingly, the parties agree that, during the Term of this
Agreement and thereafter, each party shall use and reproduce the other party's

   12
to disclose Confidential Information of the other party if required to do so

otherwise through no action or fault of the other party; (B) information that is
known to either party without restriction, prior to receipt from the other party
under this Agreement, from its own independent sources as evidenced by such
party's written records, and which was not acquired, directly or indirectly,
from the other party; (C) information that either party receives from any third
party reasonably known by such receiving party to have a legal right to transmit
such information; and not under any obligation to keep such information
confidential; and (D) information independently developed by either party's
employees or agents provided that such party can show that those same employees
or agents had no access to the Confidential Information received hereunder.

     c. PRESS RELEASES. Except to the extent permitted pursuant to the last
sentence of paragraph (a) above and except for disclosure required pursuant to
the disclosure requirements of federal or state securities laws in no event
shall either party, its employees, consultants or affiliates disclose to any
third parties or make any press release or any public announcement relating in
any way whatsoever to this Agreement without the express prior written consent
of the other party, provided, that after the initial press release announcing
this Agreement, either party may refer to the other party in press releases,
marketing materials and other promotional materials upon the prior written
consent of such other party. The parties agree to cooperate with one another to
determine the content of an initial press release relating to this Agreement and
to issue such press release on a mutually agreed upon date.

              QUEPASA.COM AND NETZERO ANNOUNCE STRATEGIC ALLIANCE

               PREMIER ONLINE COMMUNITY FOR U.S. HISPANICS JOINS
  FORCES WITH NETZERO TO BRING FREE INTERNET ACCESS TO THE U.S. LATINO MARKET

PHOENIX, AZ - DECEMBER 15, 1999 - QuePasa.com (Nasdaq: PASA), the premier
online community for U.S. Hispanics (www.quepasa.com) and NetZero, Inc.
(Nasdaq: NZRO), the nation's largest provider of free Internet access based on
number of registered users, today announced a strategic alliance whereby
NetZero will offer free Internet access along with quepasa.com's full spectrum
of content, consumer applications, and services designed for the U.S. Hispanic
market.

Under the exclusive agreement, NetZero's current and future subscribers may
select a customized quepasa.com start page that appears at each user logon and
that features highly relevant news, content and services in a bilingual format
for the Latino community. NetZero users also will have the option to select a
version of The Zeroport(TM) customized for the U.S. Hispanic market. The
ZeroPort is the unique, easy-to-use navigational tool for NetZero users that
provides "speed dial" to some of the most popular destinations on the Web.
Through the use of the ZeroPort subscribers will be able to utilize the
quepasa.com bilingual search services regardless of where they navigate on the
Internet. NetZero and quepasa.com indicated that the customized service will be
available in the first quarter of the calendar year 2000.

"Making the Internet available to every Hispanic family in the U.S. is a key
mission of quepasa.com," said Gary L. Trujillo, Chairman and CEO, quepasa.com.
"This represents a key distribution partnership to achieve our goal of
maintaining quepasa.com's focus and leadership in the U.S. Hispanic
marketplace. Quepasa.com and NetZero are working together to ensure that
Hispanic families throughout the United States will be able to participate in
the Internet revolution and be involved in a way that is culturally relevant to
the U.S. Latino community."
   20
Thirty-three million Latinos make up the fastest-growing minority in the
United States. Currently, 36% of U.S. Hispanics are online and U.S. Hispanic
households are purchasing computers at twice the rate of other U.S. households.
By the year 2000, online penetration in the U.S. Hispanic market is expected to
soar to 43%, resulting in 3.6 million US Latinos online. Using its proprietary
zCast(TM) tracking and targeting technology, NetZero will be able to provide
advertisers with valuable one-to-one marketing capabilities in this rapidly
growing market.

"The NetZero mission always has been to bring the benefits and freedom of the
Internet to the masses and to provide easy access to the wealth of content on
the Web," said Mark R. Goldston, chairman and chief executive officer of
NetZero. "This agreement allows us to provide the rich and meaningful content
of quepasa.com to our NetZero users in the U.S. Latino market."
