                              PROSPECTUS SUMMARY

    The following summary is qualified in its entirety by, and should be read in
conjunction with, the more detailed information and the Consolidated Financial
Statements and Notes thereto appearing elsewhere in this Prospectus. Unless
otherwise indicated, the information contained in this Prospectus (i) has not
been adjusted to reflect the               -for-          reverse split of the
Common Stock to be effected prior to the closing of the Offering and (ii)
assumes no exercise of the Underwriters' over-allotment option.  This Prospectus
contains forward-looking statements which involve risks and uncertainties.  The
Company's actual results could differ materially from those anticipated or
suggested in such forward-looking statements as a result of certain factors,
including those set forth under "Risk Factors" and elsewhere in this Prospectus.

                                  THE COMPANY
  
     Prodigy Communications Corporation ("Prodigy" or the "Company") is a
leading nationwide Internet service provider ("ISP") that provides fast and
reliable Internet access and related value-added services. Prodigy has
nationwide brand recognition and customer acquisition channels not available to
regional and local ISPs, and utilizes a nationwide network covering
approximately 600 cities in all 50 states allowing approximately 83% of the
United States population to access Prodigy's services with a local telephone
call. Combining these strengths with Prodigy's scalable technology has enabled
the Prodigy Internet service to achieve one of the fastest subscriber growth
rates among U.S. ISPs, with the number of billable subscribers increasing from
221,000 at December 31, 1997 to 386,000 at June 30, 1998. Prodigy Internet
enables the Internet to be used as a productivity tool by allowing subscribers
to obtain and communicate desired information quickly and efficiently in an easy
and personalized manner. Prodigy Internet users receive fast and reliable access
to the Internet, Prodigy-branded content powered by Excite and other Prodigy
member services. Prodigy is in the process of expanding its Web hosting and
electronic commerce activities for business customers, and believes that its
extensive experience in operating a large data center with electronic commerce
applications positions it well for growth in these areas. Prodigy is also in the
process of evaluating and introducing other consumer value-added services, such
as the co-branded marketing of paging, long-distance and cellular telephone
services, Internet-based telephony and fax services and online bill presentment.

     Prodigy has been an online pioneer since its inception in 1984.  Prodigy's
original online service, now called Prodigy Classic, was launched as the world's
first consumer-focused online service in 1988 and achieved national distribution
in 1990.  Prodigy Classic featured custom content, e-mail and chat capabilities
and was based on proprietary technologies.  In October 1996, the Company
launched Prodigy Internet, an open standards-based Internet access service.
Since the autumn of 1997, the Company has focused on expanding Prodigy
Internet's subscriber base and introducing additional value-added services. The
Company has also made strategic decisions to outsource its network, discontinue
its development of custom content and use multiple vendors for outsourced
customer service functions.  As a result of these initiatives, the Company has
substantially reduced its fixed operating costs and headcount and now has a
business and operating model that it believes can accommodate sustained
subscriber growth on a cost-effective basis without significant capital
expenditures.

     The Internet has grown rapidly in recent years both in terms of the number
of Web users and the number of Web sites. International Data Corporation ("IDC")
estimates that at the end of 1997 there were over 38 million Web users in the
United States and over 68 million worldwide, and projects that by the end of
2002 the number of Web users will increase to over 135 million in the United
States and over 319 million worldwide. The Internet has become an important
global medium enabling millions of people to obtain and share information and
conduct business electronically, and a critical tool for information and
communications for many users. The rapid development and growth of the Internet
has resulted in a highly fragmented industry, consisting of more than 4,000 ISPs
in the United States that provide access and related services to both consumers
and businesses.

                                       3
<PAGE>
 
     The principal market for ISPs currently consists of consumers who are
generally focused on speed and reliability of access, ease of use, customer
service and price as they evaluate an ISP.  A growing number of business
customers are beginning to focus on the Internet to extend communications and to
reach large numbers of geographically dispersed organizations and consumers
quickly and cost-effectively.  While some ISPs already offer high-speed
connections and hosting for intranets and extranets, an increasing number of
businesses are beginning to rely on ISPs for commercial services that facilitate
electronic commerce, such as Web hosting, bill presentment, co-location and
other value-added services.  Forrester Research, Inc. ("Forrester")  projects
that revenues from Internet access services in the United States will grow from
$5.8 billion in 1997 to $38.1 billion in 2002, and that Internet hosting
revenues will increase from approximately $400 million in 1997 to $10.5 billion
in 2002.  In addition to services that enable electronic commerce, a few larger
and more sophisticated ISPs are beginning to market other value-added services,
such as paging, long-distance and cellular telephone services, to both consumers
and business customers nationwide.

     Prodigy's objectives are to strengthen its position as a leading nationwide
ISP and to expand the range of services it offers and markets it serves.  Key
elements to the Company's business strategy include: leveraging the nationwide
strength of the Prodigy brand name and the nationwide access offered by Prodigy
Internet; introducing new services, including additional value-added services;
entering new markets, including small and medium sized businesses and the
Spanish-speaking and Hispanic market in the United States; and evaluating
opportunities for strategic acquisitions.

     The Company has in place a variety of nationwide customer acquisition
channels, including: PC bundling; the Microsoft relationship described below;
Web-based marketing; retail channels; direct mail and telemarketing; and
migration of subscribers from Prodigy Classic to Prodigy Internet.  Many of
Prodigy's customer acquisition channels are not available to regional and local
ISPs who lack the required nationwide presence.   The Prodigy Internet software
is included in the online services folder of every copy of the Windows 98 and
Windows 95 (OSR 2.5 release) operating systems shipped by Microsoft for sale in
retail channels or for loading on new PCs.

     Carso Global Telecom, S.A. de C.V. ("Carso Global Telecom") is the
Company's principal stockholder. Carso Global Telecom is a holding company with
ownership interests in telecommunications and media companies, including a
controlling interest in Telefonos de Mexico, S.A. de C.V. ("Telmex"), the
leading provider of local and long-distance telephone services and the largest
ISP in Mexico. Upon consummation of the Offering (and assuming an initial public
offering price of $             per share), Carso Global Telecom and Telmex 
will own     % and      %, respectively, of the Company's outstanding Common
Stock. See "Principal Stockholders". The Company is in discussions with Telmex
concerning the Company's plans to market Internet services to Spanish-speaking
and Hispanic customers in the United States. The Company is also seeking a
partner with whom to offer a Spanish language portal to the Internet, which the
Company believes will be attractive to Spanish-speaking and Hispanic Internet
users.

     The Company was incorporated in Delaware in June 1996 under the name
Prodigy, Inc. and changed its name to Prodigy Communications Corporation in
August 1998. As used in this Prospectus, unless the context otherwise requires,
the terms "Prodigy" or the "Company" refer to Prodigy Communications Corporation
and its predecessors, in each case together with their subsidiaries. See
"Corporate History and Certain Transactions". The Company's principal executive
offices are located at 44 South Broadway, White Plains, New York 10601 and its
telephone number is (914) 448-8000.

                 SUMMARY CONSOLIDATED FINANCIAL AND OTHER DATA

     Prior to June 17, 1996, the Company was a start-up company engaged in the
evaluation and development of cellular telephone systems and Internet access and
online services in Africa.  Due to the acquisition of Prodigy Services Company
("PSC") on June 17, 1996 (the "Prodigy Acquisition"), which was accounted for
under the purchase method of accounting, and the resulting change in the
Company's business and capital structure, the historical financial statements of
the Company are not directly comparable.  The aggregate purchase price for the
Prodigy Acquisition of $78.1 million consisted of a cash payment of $40.8
million, the issuance of Contingent Notes valued at $30.5 million and direct
acquisition related expenses of $6.8 million.  See "Corporate History and
Certain Transactions -- Acquisition of Prodigy Services Company" and " -- Prior
Corporate History".  The pro forma data set forth below assumes that the Prodigy
Acquisition occurred as of January 1, 1995 and, although not required by
generally accepted accounting principles ("GAAP"), is presented herein because
the Company believes this information presents the most meaningful basis of
comparison of the Company's results of operations in view of the significant
change in its business resulting from the Prodigy Acquisition.  The pro forma
data is presented for illustrative purposes only and is not necessarily
indicative of the results of operations that would have occurred had the Prodigy
Acquisition actually been consummated as of January 1, 1995, nor is it intended
to indicate the Company's financial position or results of operations for any
future date or period.  For further information regarding the pro forma data,
see "Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Pro Forma Results of Operations".

     The following tables set forth selected consolidated financial and other
data for the Company and PSC for the periods indicated. The results of
operations for the six months ended June 30, 1998 are not necessarily indicative
of the results for the entire year or for any future period. The following
information should be read in conjunction with the Consolidated Financial
Statements and Notes thereto of the Company and PSC appearing elsewhere in this
Prospectus, "Selected Consolidated Financial Information and Other Data" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations".

     recurring charge for acquired incomplete technology relating to the
     acquisition; (ii) reflect the amortization over ten years of intangible
     assets acquired as a result of the Prodigy Acquisition to reflect a full
     year's charge in both years presented; (iii) reflect interest expense on
     additional borrowings to finance the acquisition, at an assumed interest
     rate of 8.75% per annum; (iv) reflect the amortization of unfavorable lease
     agreements recognized as a result of the Prodigy Acquisition over the lease
     term to reflect a full year's credit in both years presented; and (v)
     reduce the depreciation charge for property and equipment as a result of
     the fair valuation of these assets at the time of the Prodigy Acquisition.

HISTORY OF LOSSES

     Since inception, the Company has incurred significant losses.  During the
six months ended June 30, 1997 and 1998, the Company incurred net losses of
$52.8 million and $31.9 million, respectively, on revenues of $69.5 million and
$67.3 million, respectively.  At June 30, 1998, the Company had an accumulated
deficit of $279.3 million and a stockholders' deficit of $18.2 million.  During
the years ended December 31, 1996 and 1997, the Company incurred net losses of
$114.1 million and $129.3 million, respectively, on revenues of $98.9 million
and $134.2 million, respectively.  Prior to its acquisition by the Company on
June 17, 1996, Prodigy Services Company incurred net losses of $60.0 million,
$52.0 million, $34.6 million and $62.9 million in the years ended December 31,
1993, 1994 and 1995 and the five and one-half months ended June 16, 1996,
respectively.  As of June 16, 1996, Prodigy Services Company (which had been
operated by its former owners as a partnership) had an accumulated partners'
capital deficit of $1.3 billion.  There can be no assurance that the Company
will be able to achieve or sustain profitability. See "Selected Consolidated
Financial Information and Other Data", "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and the Consolidated Financial
Statements and Notes thereto contained herein.

INTENSE COMPETITION

     The industry in which the Company competes is intensely competitive and
includes a number of significant participants, including ISPs, proprietary
online service providers and major international telecommunications companies,
as well as Internet-search services and various other telecommunications
companies.  Moreover, the Company faces competition from companies that provide
broadband connections to households, including local and long-distance telephone
companies, cable television companies and electric utility companies.  Broadband
technologies offer significantly faster Internet access than conventional
modems, and such companies could include Internet access in their basic service
packages, could offer access for a nominal additional charge or could prevent
the Company from delivering Internet access through the cable or wire
connections that such companies own.  The Telecommunications Act of 1996 (the
"Telecommunications Act") contains certain provisions that remove, or establish
procedures for removing, restrictions on the regional Bell operating companies
and others that may permit them to engage directly in the Internet access
business.  The Telecommunications Act also makes it easier for national long-
distance carriers, such as AT&T, to offer local telephone service, which would
permit such carriers to offer direct local Internet access.  Competition from
these companies could have a material adverse effect on the Company.  The
Company cannot predict the extent to which the Telecommunications Act, or
strategic alliances or consolidation among ISPs, may result in additional
competitive pressures on the Company.

     Among the larger providers of ISP services are EarthLink Network, Inc.
(which has a strategic relationship with Sprint Corporation), MindSpring
Enterprises, Inc., Microsoft Network, AT&T WorldNet, MCI Internet, IBM Internet
Connection, PSINet Inc., GTE Internetworking (which includes the former ISP
business of BBN Corporation), Netcom On-Line Communications Services, Inc.
(owned by ICG 


                                       9
<PAGE>
 
Communications, Inc.) and Concentric Network Corporation. Microsoft's ownership
of the dominant PC operating system and the Microsoft Internet Explorer browser
may give Microsoft Network certain competitive advantages, including
distribution and marketing synergies. Prodigy also competes with America Online,
which offers the America Online and CompuServe proprietary online services over
closed networks, as well as Internet access.

     The market for Internet and online services is presently characterized by
low operating margins and minimal profitability.  The introduction of unlimited
usage plans and the elimination of most hourly access charges throughout the
industry has placed further pressure on revenues and profit margins.  Many of
the Company's current and future competitors have substantially greater
financial, marketing and technical resources than the Company.  The Company
believes that competition will increase and that increased competition could
lead to lower pricing to customers and greater spending on marketing. Increased
competition could also adversely affect the Company's ability to develop new
service offerings and interfere with the Company's efforts to maintain or grow
its subscriber base.  Any of the foregoing factors could have a material adverse
effect on the Company.  There can be no assurance the Company will be able to
compete effectively or that price competition will not have a material adverse
effect on the Company's business, financial condition, results of operations or
prospects.  See "Business -- Competition".

SUBSCRIBER TURNOVER

     The results of operations of ISPs, including the Company, are significantly
affected by subscriber cancellations.  Customer acquisition expenses and the
administrative expenses of enrolling and assisting new subscribers are
substantial.  Accordingly, the Company's operating results are adversely
affected by subscriber cancellations.  The failure to attract and retain
subscribers to the Company's services, or an increase in, or a failure to slow,
the rate of subscriber cancellations, would have a material adverse effect on
the Company.  Since launch in October 1996, the Prodigy Internet service has
grown to 386,000 billable subscribers at June 30, 1998, including migration from
Prodigy Classic.  The total number of billable subscribers (including billable
subscribers to Prodigy Internet and Prodigy Classic) declined from 1,133,000 at
December 31, 1995 to 814,000 at December 31, 1996 and to 615,000 at December 31,
1997, but increased to 638,000 at June 30, 1998.  See "Management's Discussion
and Analysis of Financial Condition and Results of Operations", "Business" and
the Consolidated Financial Statements and Notes thereto contained herein.

NETWORK RISKS

     Effective July 1, 1997, Prodigy conveyed its network assets to Splitrock
Services, Inc. ("Splitrock") in exchange for Splitrock's agreement to build and
operate a network to carry Prodigy's traffic between subscribers and Prodigy's
data hosting center.  Splitrock is required to meet specified service level
objectives relating to grade of service, site and overall system availability
and average transit delays, and to comply with certain financial covenants.  In
certain circumstances, Prodigy has the right to assume responsibility for
operating the network at Splitrock's expense.  Although the Company believes
these network arrangements present a number of significant advantages to
Prodigy, there are associated risks. Splitrock was formed in 1997 and has a
limited operating history, and Prodigy currently is its only significant
customer.  See "Risk Factors -- Potential Conflicts of Interest".  The failure
by Splitrock for any reason to provide network services as required, or any
significant disruption in such services, whether for technical, operational or
financial reasons, would have a material adverse effect on the Company.  The
Splitrock arrangements cover only the United States, and the Company will need
to make other network arrangements in order to offer services in foreign
countries.  See "-- Rapidly Changing Markets and Technology" and "Business --
Principal Outsourcing Arrangements".

     Security problems represent an ongoing threat to public and private data
networks and related telecommunications infrastructures.  Splitrock's network
and the Company's data hosting center are potentially vulnerable to computer
viruses, break-ins and similar disruptions caused by others which 

                                      10
<PAGE>
 
could lead to service interruptions to the Company's customers. Inappropriate
use of the Internet by third parties could potentially jeopardize the
confidentiality of information stored or transmitted by the Company's customers.
The security measures employed by Splitrock and the Company cannot assure
complete protection from computer viruses, break-ins and other disruptions. The
occurrence of such problems may result in claims against or liability on the
part of the Company and could adversely affect the Company or its ability to
attract and retain customers.

     The Company's operations are also dependent on the protection of
Splitrock's network and the Company's data hosting center against damage from
fire, power loss, telecommunications failures and similar events. The Company's
host configuration for Prodigy Classic and Prodigy Internet is unique and, for
cost reasons, has not been replicated off site. The occurrence of a natural
disaster, other catastrophe or other unanticipated problems in Splitrock's
network or the Company's data hosting center, or the failure of
telecommunications providers to provide required data communications capacity as
a result of a natural disaster, operational disruption or for any other reason,
could cause interruptions in the services provided by the Company, and such
service interruptions could have a material adverse effect on the Company.

     In addition to technical problems and network failures that occur from time
to time in the ordinary course of operating a telecommunications network, in
connection with the migration of the Company's subscribers to the Splitrock
network, Prodigy experienced significant service interruptions and failures, the
most prolonged and serious of which occurred in February, March and April of
1998.  The Company believes Splitrock and Splitrock's modem vendor have
addressed the causes of these service interruptions and failures, but there can
be no assurance these or similar problems will not recur in the future.  See
"Business -- Network and Related Infrastructure".

RELIANCE ON THIRD-PARTY PROVIDERS

     In addition to its network arrangements with Splitrock, the Company has
outsourced its content and aspects of its customer service and billing
functions.  Although the Company believes its outsourcing strategy permits it to
control costs, enhance service quality and focus on its core strengths,
outsourcing also makes the Company reliant on third-party providers for certain
critical functions.  The failure of these providers to provide services as
required, or any significant disruption of or deterioration in services, would
have a material adverse effect on the Company.  The Company also relies on local
telephone companies and other companies to provide data communications capacity
via local telecommunications lines and leased long-distance lines.  The
Telecommunications Act generally is expected to lead to increased competition in
the provision of local and other telephone service, but the Company cannot
predict the timing or extent of any such developments or the effect thereof on
pricing or supply.  The Company's suppliers and telecommunications carriers also
sell or lease products and services to the Company's competitors and may be, or
in the future may become, competitors of the Company.  There can be no assurance
that the Company's suppliers and telecommunications carriers will not enter into
exclusive arrangements with the Company's competitors or stop selling or leasing
their products or services to the Company at commercially reasonable prices or
at all.  See "Business -- Products and Services", "Business -- Customer Service"
and "Business -- Principal Outsourcing Arrangements".

CONTROL OF THE COMPANY AND POTENTIAL CONFLICTS OF INTEREST

     As of August 31, 1998, Carso Global Telecom, the Company's principal
stockholder, owned 117,587,644 shares of Common Stock, representing 65.3% of the
outstanding Common Stock, and Telmex owned 37,650,000 shares of Common Stock,
representing 20.9% of the outstanding Common Stock. Mr. Carlos Slim Helu, a
Mexican citizen, and certain members of his immediate family, directly and
through their ownership of a majority of the voting and economic interests in
two trusts, own a majority of the outstanding voting equity securities of Carso
Global Telecom, Grupo Carso, S.A. de C.V. ("Grupo Carso") and Grupo Financiero
Inbursa, S.A. de C.V. ("Grupo Financiero").  Mr. Slim is Chairman of the 

                                      11
<PAGE>
 
Board of Carso Global Telecom, Grupo Carso, Grupo Financiero and Telmex. Carso
Global Telecom owns a controlling interest in a trust (that will terminate on
December 20, 2000) that owns a majority of Telmex's outstanding regular voting
equity securities, and Mr. Slim and his family, Carso Global Telecom, Grupo
Carso and Grupo Financiero also own additional equity securities of Telmex
directly. As a result of the foregoing arrangements, Carso Global Telecom may be
deemed to control Telmex, and Mr. Slim may be deemed to control Carso Global
Telecom, Telmex and the Company. After giving effect to the Offering and the
conversion of the Contingent Notes held by IBM and Sears into an aggregate of
          shares of Common Stock upon the closing of the Offering (at an assumed
initial public offering price of $     per share) and assuming that Carso Global
Telecom and Telmex do not purchase any shares in the Offering, Carso Global
Telecom will beneficially own (directly or through its control of Telmex)     %
of the Common Stock outstanding upon consummation of the Offering. In addition,
IBM and Sears have agreed to vote their shares of Common Stock received upon
conversion of the Contingent Notes or exercise of the Contingent Warrants held
by them in accordance with the voting recommendations of the Company's Board of
Directors. As a result, Carso Global Telecom is able to determine the outcome of
all matters submitted to a vote of the stockholders, including the power to
elect all members of the Company's Board of Directors, and control the
management and affairs of the Company. Circumstances may arise in which the
interests of Carso Global Telecom and/or Telmex, as stockholders of the Company,
could conflict with the interests of the other stockholders of the Company. The
voting control of Carso Global Telecom could be used as a means or have the
effect of delaying or preventing a change in control or acquisition of the
Company.

     Carso Global Telecom, the Company's principal stockholder, currently owns
30.2% of Splitrock's common stock.  Samer F. Salameh, the Company's Chairman of
the Board, President and Chief Executive Officer, serves on Splitrock's Board of
Directors and holds stock options to purchase 80,000 shares of Splitrock's
common stock (approximately 0.1% of the outstanding shares) at $1.10 per share
vesting over four years.  Mr. Salameh also serves as an Advisor to the Chief
Executive Officer of Telmex.  In addition, four of the Company's current six
directors are affiliated with Carso Global Telecom, Telmex or Grupo Financiero,
Mr. Salameh is married to Mr. Slim's niece and Mr. Elias is married to Mr.
Slim's daughter. Carso Global Telecom currently provides the Company with a
$35.6 million revolving line of credit. Furthermore, the Company and Carso
Global Telecom and its affiliates have engaged in numerous transactions in the
past and may do so in the future.  The line of credit and previous transactions
between the Company and Carso Global Telecom and its affiliates were not
necessarily a result of arm's length negotiations.  Any decision made by the
Company's directors is required by law to be made in accordance with their
fiduciary duties and in the best interests of the Company and its stockholders.
Messrs. Salameh, Elias, Nakfoor and Sanchez, directors of the Company, owe
similar duties to the other companies for which they serve as directors or
officers or with which they are otherwise affiliated.  Due to the nature of the
potential conflicts of interest presented on an ongoing basis by these
arrangements, and potential future arrangements, there can be no assurance that
the directors involved will act in the best interests of the Company and its
stockholders.  See "Management", "Corporate History and Certain Transactions"
and "Principal Stockholders".

NEED FOR ADDITIONAL FINANCING

     At August 31, 1998, the Company had cash of $35.0 million (of which $4.1
million secured a letter of credit and was thus unavailable).  The Company is
currently experiencing substantial negative cash flow each month and expects to
continue to experience negative cash flow through at least the end of 1999.  The
Company's future financing requirements will depend on a number of factors,
including the Company's operating performance and increases in operating
expenses associated with growth in the Company's business.  Based on its current
operating plan, the Company believes that the net proceeds from the Offering,
together with its existing cash and available financing under its revolving
credit facility with Carso Global Telecom, will be sufficient to meet its
anticipated cash requirements for at least the next twelve months.  The Company
has made no arrangements to obtain additional financing, other than 

                                      12

<PAGE>
 
pursuant to the Carso Global Telecom credit facility, and there can be no
assurance that adequate additional financing on acceptable terms will be
available when needed, if at all. The unavailability of sufficient financing
when needed would have a material adverse effect on the Company. Any additional
equity financing may cause investors to experience dilution and any additional
debt financing may result in restrictions on Prodigy's operations or its ability
to pay dividends in the future. See "Dividend Policy", "Management's Discussion
and Analysis of Financial Condition and Results of Operations", "Business" and
the Consolidated Financial Statements and Notes thereto contained herein.

DEPENDENCE ON PC BUNDLING AND MICROSOFT RELATIONSHIP

     The Company's largest customer acquisition channel is its bundling
arrangements with PC manufacturers.  During the year ended December 31, 1997 and
the six months ended June 30, 1998, approximately 48% and 45%, respectively, of
total Prodigy Internet enrollments resulted from PC bundling.  Prodigy's
bundling arrangements with Packard Bell/NEC accounted for approximately 36% and
33%, respectively, of total Prodigy Internet enrollments during such periods.
The Company also relies to a significant extent on its relationship with
Microsoft to generate Prodigy Internet enrollments.  During the year ended
December 31, 1997 and the six months ended June 30, 1998, approximately 10% and
11%, respectively, of total Prodigy Internet enrollments resulted from Prodigy's
relationship with Microsoft. The Company's bundling agreement with Packard
Bell/NEC automatically renews from year to year but is terminable by either
party upon 30 days' written notice.  The Company's agreements with Microsoft for
inclusion of Prodigy Internet in the online services folder of Microsoft's
Windows 98 and Windows 95 (OSR 2.5 release) operating systems expire in June
1999.  The loss of any of these relationships or any significant reduction in
enrollments from these channels would have a material adverse effect on the
Company.  See "Business -- Customer Acquisition and Marketing".

MIGRATION FROM PRODIGY CLASSIC SERVICE

     Prodigy Classic has been a significant source of the Company's revenues and
subscribers to Prodigy Internet.  During the years ended December 31, 1996 and
1997 and the six months ended June 30, 1998, approximately 92%, 73% and 41%,
respectively, of the Company's total revenues were attributable to Prodigy
Classic.  Because the Company has shifted its business focus to Internet-based
products and services, the Company intends to continue to migrate users of
Prodigy Classic to Prodigy Internet.  As a result, the Company expects revenues
from Prodigy Classic to continue to decline over the next 12 to 15 months.  As
of June 30, 1998, 143,000 of the Prodigy Internet subscribers had migrated from
Prodigy Classic (most of whom are enrolled in a Prodigy Internet/Prodigy Classic
combination plan), and there were 257,000 remaining subscribers to Prodigy
Classic.  Although the Company plans to continue to encourage Prodigy Classic
subscribers to migrate to the Prodigy Internet service, the Company has
experienced difficulty in generating migration from Prodigy Classic to Prodigy
Internet, and a substantial portion of the remaining Prodigy Classic subscribers
lack the minimum hardware requirements for the Prodigy Internet service.  No
assurance can be given as to the number of remaining Prodigy Classic subscribers
who will migrate to Prodigy Internet.  In addition, a majority of the
subscribers enrolled in a Prodigy Internet/Prodigy Classic combination plan
(61,000 of 111,000 at June 30, 1998) use both services and some combination plan
subscribers (14,000 of 111,000 at June 30, 1998) do not use Prodigy Internet at
all.  Accordingly, some combination plan subscribers may be unwilling or unable
to migrate to Prodigy Internet.  The foregoing factors could adversely affect
the Company's business, financial condition, results of operations or prospects.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations", "Business" and the Consolidated Financial Statements and Notes
thereto contained herein.

DEPENDENCE ON THE INTERNET

     Substantially all of the Company's revenues are dependent on the continued
use and expansion of the Internet.  Only recently has the commercial sector
begun significant use of the Internet and, more recently still, have consumers
begun using the Internet.  Use of the Internet has grown dramatically, but no
assurance can be given of the continued use and expansion of the Internet as a
medium of communications and commerce.  A decrease in the demand for Internet
services or a reduction in the currently anticipated growth for such services
could have a material adverse effect on the Company's business, financial
condition, results of operations or prospects.  This Prospectus includes
statistical data regarding the Internet industry taken or derived from published
sources.  Although the Company believes that such data are generally indicative
of the matters reflected therein, such data are inherently imprecise and
investors are cautioned not to place undue reliance on such data.  See "Business
- -- Industry Background".

UNCERTAIN LEGAL STANDARDS

     The law relating to the liability of ISPs and online services companies for
information available through their services is uncertain.  As the law and
judicial decisions in this area develop, the potential imposition of liability
upon the Company for information available through its services could require
the Company to implement measures to reduce its exposure to such liability.  The
implementation of such measures could require the expenditure of substantial
resources or the discontinuation of certain service offerings.  Any costs that
are incurred as a result of such expenditures, contesting any such asserted
claims or the imposition of liability could have a material adverse effect on
the Company's business, financial condition, results of operations or prospects.
In addition, due to the increasing use of the Internet, it is possible that
additional laws and regulations may be adopted with respect to the Internet
covering issues such as content, user privacy, pricing, libel, intellectual
property protection and infringement and technology export and other controls.
Changes in the regulatory environment relating to the Internet services
industry, including regulatory changes that directly or indirectly affect
telecommunication costs or increase the likelihood or scope of competition,
could have a material adverse effect on the Company. "Business -- Government
Regulation".

RAPIDLY CHANGING MARKETS AND TECHNOLOGY

     The industry in which the Company competes is characterized by rapid
technological change resulting in dynamic customer demands and frequent new
product and service introductions.  As a result, the Company's markets can
change rapidly and the Company's future results will depend in part on its
ability to make timely and cost-effective enhancements and additions to its
services and introduce new services that meet customer demands.  For example,
certain ISPs have introduced, or announced plans to introduce, high-speed
Internet access utilizing broadband applications such as cable modems,
Integrated Services Digital Network ("ISDN") telephone service and Asymmetric
Digital Subscriber Line ("ADSL") telephone service.  The Company does not
currently provide any residential broadband access services. Although the
Company is in discussions with Splitrock and others to support various broadband
applications, there can be no assurance the Company and Splitrock or any other
party will reach agreement.  See "Business -- Products and Services -- Business
Services".  There also can be no assurance that the Company will have sufficient
resources to introduce new services that meet customer demands on a timely basis
or that its new service introductions will achieve acceptance in the
marketplace.  The Company believes that its ability to compete successfully is
also dependent upon the continued compatibility and interoperability of its
services with products and architectures offered by various vendors.  Although
the Company intends to support emerging standards in the market for Internet
access, there can be no assurance that the Company will be able to conform to
new standards in a timely fashion and maintain a competitive position in its
markets.  In addition, there can be no assurance that services or technologies
developed by others will not render the Company's services or technology
uncompetitive or obsolete.  See "Business".

                                      14
<PAGE>
 
RISKS OF NEW SERVICES AND MARKETS; FAILURE TO IMPLEMENT BUSINESS STRATEGY

     The Company's business strategy includes the introduction of numerous new
services and entry into various new markets.  For example, the Company is
expanding its Web hosting activities and other value-added services, plans to
expand beyond its existing consumer market to include small and medium sized
businesses, and plans to provide Internet services to Spanish-speaking and
Hispanic customers in the United States.  See "Use of Proceeds", "Business --
Business Strategy" and "Business -- Products and Services".  The Company
historically has focused on the consumer market and has relatively little
experience in developing and marketing services to business customers.  In
addition, the Company has not previously focused on Spanish-speaking or Hispanic
customers, and the Company's success in penetrating this market will depend in
large part on the Company's ability to establish a strategic partnership with
Telmex or another company with experience in selling products or services to
this market.  There can be no assurance that the Company will be successful in
offering new services and entering new markets as planned or that any such
services, if introduced, will achieve acceptance in the marketplace.

     The Company may decide to alter or discontinue certain aspects of its
business strategy described herein and may adopt alternative or additional
strategies.  The Company's ability to successfully implement its business
strategy, and the expected benefits to be obtained from the Company's strategy,
may be adversely impacted by factors not currently foreseen, such as unforeseen
costs and expenses, or events beyond its control, such as technological change
or an economic downturn.  In addition, competitive factors may require the
Company to alter or reduce its business strategies or reduce the expected
benefits to be obtained therefrom.

QUARTERLY FLUCTUATIONS IN OPERATING RESULTS

     The Company experiences quarterly fluctuations in its operating results due
to a number of factors, including the seasonality of its business, changes in
the level of consumer spending during business cycles, the timing of
introduction of new and enhanced services by the Company, pricing changes and
competitive factors.   The Company historically has experienced seasonality in
its business, with higher expenses during the last and first fiscal quarters,
corresponding to the Christmas and post-Christmas selling season, and lower
timed usage revenues typically occurring during its second and third fiscal
quarters resulting from reduced usage of its services during the summer months.
The Company believes that the seasonal reductions in timed usage revenues
historically experienced by the Company will be mitigated by the movement from
timed usage plans to unlimited usage plans as well as growth in the Company's
subscriber base, although the Company expects to continue to have higher
expenses during the first and fourth quarters.  Accordingly, the Company
believes that quarter-to-quarter comparisons of the Company's operating results
may not be meaningful or indicative of future results. Although the Company's
outsourcing strategy enables it to tie many variable costs to variable revenue
sources, the Company's fixed expenses are based, in part, on its expectations as
to future revenues.  To the extent that revenues are below expectations and the
Company is unable to reduce fixed costs proportionately, the Company's operating
results would be adversely affected.  See "Management's Discussion and Analysis
of Financial Condition and Results of Operations", "Business" and the
Consolidated Financial Statements and Notes thereto contained herein.

PROTECTION OF PROPRIETARY TECHNOLOGY

     The Company protects its proprietary technology through copyright and trade
secrets laws, employee and third-party confidentiality agreements and other
methods.  Customers are granted a license to use Prodigy's services under
agreements that contain terms and conditions prohibiting unauthorized
reproduction.  Despite these precautions, unauthorized third parties may be able
to copy certain portions of Prodigy's services or reverse engineer or obtain and
use information Prodigy regards as proprietary. 

                                      15
<PAGE>
 
Although the Company does not believe that its products infringe the proprietary
rights of any third parties, there can be no assurance that third parties will
not assert infringement claims against the Company or that such claims will not
be successful. The Company could incur substantial costs and diversion of
management resources with respect to any claims relating to proprietary rights,
whether or not successful, which could materially adversely affect the Company's
business, financial condition, results of operations or prospects. See 
"Business -- Technology" and "--Proprietary Rights".

MANAGEMENT OF GROWTH AND DEPENDENCE ON KEY PERSONNEL

     The Company's ability to exploit the market for its products and services
and increase its subscriber base requires an effective planning and management
process.  The Company's ability to plan and manage effectively will require it
to continue to implement and improve its operational, financial and management
information systems and to attract and retain skilled managers and other
personnel, including its current executive officers.  Competition for such
personnel is intense, and there can be no assurance that the Company will be
successful in attracting and retaining necessary personnel.  The Company does
not maintain insurance on the lives of any of its officers or directors.
Although the Company has entered into non-competition agreements with certain
executive officers, no assurance can be given that such agreements are or will
be enforceable by the Company.  Many of the Company's executive officers have
joined the Company since the autumn of 1997, including Samer F. Salameh,
Chairman of the Board, President and Chief Executive Officer, David R. Henkel,
Executive Vice President, Finance and Chief Financial Officer, James P.
Dougherty, Executive Vice President, Business Services and Andrea S. Hirsch,
Executive Vice President, Business Development and General Counsel.  See
"Management".

GOVERNMENT REGULATION

     Internet access and online services are not subject to direct regulation in
the United States, but changes in the regulatory environment relating to the
telecommunications and media industry could have an effect on Prodigy's
business, financial condition, results of operations or prospects.  For example,
Federal Communications Commission regulatory review and rulemaking could result
in regulation of the Internet and online services industry which could result in
increased telecommunications costs for participants in the Internet industry,
including Prodigy.  The Company cannot predict whether, or to what extent, any
such new rulemaking will occur, or what effect any such rulemaking would have on
Prodigy. There can be no assurance the Company will not be adversely affected by
any such matters.  See "Business -- Government Regulation".

IMPACT OF THE YEAR 2000 ISSUE

  The Year 2000 issue is the result of computer programs being written using two
digits (rather than four) to define the applicable year.  Computer programs that
have time-sensitive software may recognize a date using "00" as the year 1900
rather than the year 2000.  This could result in a system failure or
miscalculations causing disruptions of operations, including among other things,
a temporary inability to process transactions, send invoices or engage in other
normal business activities.  The Company maintains various internal computer
systems and equipment and contracts with third-party vendors for the provision
of computerized customer billing, network operation, Prodigy Internet service
content and certain other information technology and other services.

  The Company is currently incurring costs to resolve the potential impact of
the year 2000 on the processing of date-sensitive information by the Company's
internal computer systems and equipment and the computer systems and equipment
of the third-party vendors on which the Company's business relies. The Company
has established a Year 2000 project office staffed by Company personnel and
assisted by a consulting firm.

                                      16
<PAGE>
 
  The Company has completed an inventory of substantially all of its internal
systems and programs related to both the delivery of the Prodigy Internet
service and the daily operations of the business.  Based on its preliminary
analysis, the Company estimates that it will spend approximately $3.5 million
through the end of 1999 to remediate potential Year 2000 problems with its
internal systems.  See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Liquidity and Capital Resources".

  The Company is developing contingency plans in the event that any critical
service component or business process fails due to a Year 2000 problem. The
Company expects to complete contingency planning by mid-1999. With respect to
critical third-party vendor systems, Splitrock has publicly reported that its
network services will be Year 2000 compliant, Excite has publicly reported that
there are no significant Year 2000 issues within its systems or services, and
Prodigy's billing provider has committed to making its billing system Year 2000
compliant.  There can be no assurance that the Company will be able to address,
in a timely fashion, all potential Year 2000 problems, or that the systems of
the third-party vendors upon which the Company's business relies (and the
maintenance and operation of which are not within the control of the Company)
will be Year 2000 compliant or will become Year 2000 compliant in a timely
manner.  Any Year 2000 problems could impact the provision of products or
services to the Company's customers and could subject the Company to the risk of
litigation, lost revenues and loss of current or future customers.

POSSIBLE ACQUISITIONS

     The Internet services industry is highly fragmented, consisting of more
than 4,000 ISPs in the United States, and is expected to undergo substantial
consolidation over the next few years.  The Company evaluates acquisition
opportunities on an ongoing basis and, from time to time, is engaged in
discussions with respect to possible acquisitions or other business
combinations.  The Company may seek strategic acquisitions that can complement
the Company's current or planned business activities, particularly the expansion
of value-added services such as Web hosting.  The Company may also seek to
acquire other ISPs as an additional means of customer acquisition or entry into
new markets.  Such acquisitions may not be available at the times or on terms
acceptable to the Company, or may not be available at all.  In addition, any
acquisitions that the Company makes may involve risks, including the successful
integration and management of acquired operations and personnel.  The
integration of acquired businesses may also lead to the diversion of management
attention from other business matters.  No assurance can be given that suitable
acquisitions can be identified, financed and completed on acceptable terms or
that any acquisitions by the Company will be successful.  See "Business --
Business Strategy".

MANAGEMENT DISCRETION REGARDING USE OF PROCEEDS

     The Company intends to use a significant portion of the net proceeds from
the Offering for working capital and other general corporate purposes.  In
addition, the Company is not required to allocate the net proceeds of the
Offering in the manner described herein and, in light of future developments and
circumstances, may allocate the proceeds to other uses or in a different manner.
Accordingly, the Company's management will have significant discretion in how
the net proceeds of the Offering are utilized in the Company's business.  See
"Use of Proceeds".

LEGAL PROCEEDINGS

     On November 27, 1996, Malcolm Haynes and Lightwave, Ltd., a Cayman Islands
corporation ("Lightwave"), filed a lawsuit in the District Court of Clark
County, Nevada, against the Company, International Wireless Incorporated (the
Company's predecessor) ("IW"), Comstar Cellular Network, Inc. ("Comstar"), Greg
C. Carr, Terrance P. Dillon, Duncan E. Wine and Blaize Kaduru.  Mr. Carr is the
former Chairman of the Board of the Company and a former principal stockholder
of the Company, and was a 

                                      17
<PAGE>
 
director and principal stockholder of IW. Mr. Dillon was a director and
principal stockholder of the Company, was a director, officer and principal
stockholder of IW and was a director and technical advisor to Comstar. Mr. Wine
is a former principal stockholder of the Company and IW. Mr. Kaduru is a former
principal stockholder of the Company and IW, was an officer of IW and was a
director and officer of Comstar. Mr. Haynes was co-founder, President and a
director of Comstar and claims that he and Mr. Wine each hold a 30% interest in
Lightwave. The lawsuit arose from IW's acquisition of the assets and liabilities
of Comstar in August 1994. See "Corporate History and Certain Transactions --
Prior Corporate History". In connection with the Comstar acquisition, IW issued
to Comstar all then outstanding common stock of IW, which Comstar then
distributed as a liquidating dividend to the holders of certificates for common
stock of Comstar. Each holder of a certificate for common stock of Comstar was
required to acknowledge and accept the terms of the Comstar acquisition and
release Comstar and IW from all claims which such holder may have had against
either Comstar or IW. Pursuant to the foregoing, Comstar offered 4,800,000
shares of IW's common stock to Mr. Haynes, but Mr. Haynes refused to participate
and therefore received no shares. The lawsuit filed by Mr. Haynes and Lightwave
alleges, among other things, that Messrs. Dillon, Wine and Kaduru breached their
fiduciary duties to the plaintiffs, that Mr. Wine defrauded or made
misrepresentations to the plaintiffs, that Mr. Wine misappropriated a corporate
opportunity belonging to Lightwave, that all defendants are liable for
conversion of plaintiffs' shares of common stock, and that IW and Mr. Carr aided
and abetted the wrongful conduct of Messrs. Dillon, Wine and Kaduru. The lawsuit
seeks to compel the defendants to provide to the plaintiffs 18,000,000 shares of
Common Stock of the Company or the fair market value thereof, to impose a
constructive trust on the shares of Common Stock received by Messrs. Dillon,
Wine and Kaduru in the Comstar acquisition, and other monetary damages and
declaratory and equitable relief. On February 25, 1998, the Court granted the
motion of the Company and Mr. Carr to dismiss the lawsuit against them for lack
of personal jurisdiction in Nevada, and the lawsuit is continuing against the
other defendants. Unless this decision is overturned on appeal, the plaintiffs
cannot pursue this lawsuit against the Company and Mr. Carr in Nevada, although
the plaintiffs could pursue these claims in a new lawsuit filed in any state or
states where personal jurisdiction over the Company and Mr. Carr could be
established and where the applicable statute of limitations has not expired. If
a new lawsuit is filed, the Company intends to defend it vigorously, but there
can be no assurance that its outcome would not have a material adverse effect on
the Company's business, financial condition, results of operations or prospects
or result in substantial dilution to the Company's stockholders. See 
"Business -- Legal Proceedings".

NO PUBLIC MARKET; POSSIBLE VOLATILITY OF STOCK PRICE

     Prior to the Offering, there has been no public market for the Common
Stock, and there can be no assurance that an active trading market will develop
or be sustained after the Offering or that the market price of the Common Stock
will not decline below the initial public offering price.  The initial public
offering price will be determined by negotiations among the Company and the
representatives of the Underwriters (the "Representatives").  See "Underwriting"
for information relating to the factors to be considered in determining the
initial public offering price of the Common Stock.  Investors should be aware
that market prices for securities of ISPs and other participants in the Internet
industry have been and may continue to be highly volatile.  Such volatility may
be caused by factors outside of the Company's control and may be unrelated or
disproportionate to the Company's operating results.

SHARES ELIGIBLE FOR FUTURE SALE; REGISTRATION RIGHTS

     Sales of substantial amounts of shares of Common Stock in the public market
following the Offering could adversely affect the market price of the Common
Stock.  Upon completion of the Offering (at an assumed initial public offering
price of $           per share), the Company will have outstanding
shares of Common Stock.  In addition to the                 shares offered
hereby, approximately            shares of Common Stock, which are not subject
to 180-day lock-up agreements (the "Lock-up Agreements") with the
Representatives, will be eligible for immediate sale in the public market

                                      18
<PAGE>
 
pursuant to Rule 144(k) under the Securities Act of 1933, as amended (the
"Securities Act"). Approximately                  additional shares of Common
Stock, which are not subject to the Lock-up Agreements, will be eligible for
sale in the public market in accordance with Rule 144 or Rule 701 under the
Securities Act beginning 90 days after the date of this Prospectus.  Upon
expiration of the Lock-up Agreements 180 days after the date of this Prospectus,
approximately                  additional shares of Common Stock will be
available for sale in the public market, subject to the provisions of Rule 144
under the Securities Act.  Promptly following the consummation of the Offering,
the Company intends to register an aggregate of             shares of Common
Stock issuable under its 1996 Stock Option Plan and 1998 Employee Stock Purchase
Plan.  The Company and certain stockholders of the Company (including Carso
Global Telecom, Telmex, IBM, Sears and all directors and executive officers of
the Company) who will hold, upon consummation of the Offering at an assumed
initial public offering price of $       per share, an aggregate of
approximately                 shares of Common Stock, have agreed, pursuant to
the Lock-up Agreements, not to offer, sell, contract to sell or otherwise
dispose of any Common Stock, or any options, warrants or other securities
convertible into or exercisable for Common Stock, for 180 days after the date of
this Prospectus.  The Company is unable to predict the effect that sales made
under Rule 144, Rule 701 or otherwise may have on the then prevailing market
price of the Common Stock.  Upon the closing of the Offering (at an assumed
initial public offering price of $           per share), IBM and Sears will be
entitled to certain piggyback and demand registration rights with respect to an
aggregate of (i)                shares of Common Stock issued upon the
conversion of the Contingent Notes held by them and (ii)                  shares
of Common Stock issuable upon the exercise of the Contingent Warrants held by
them.  In addition, Greg C. Carr has piggyback registration rights with respect
to               shares held by him.  Exercise of the foregoing registration
rights could cause a large number of shares to be registered and sold in the
public market.  Sales pursuant to Rule 144, Rule 701 or other exemptions from
registration, or pursuant to registration rights, may have an adverse effect on
the market price for the Common Stock and could impair the Company's ability to
raise capital through offerings of its equity securities.  See "Description of
Capital Stock", "Shares Eligible for Future Sale", "Underwriting" and "Corporate
History and Certain Transactions".

IMMEDIATE AND SUBSTANTIAL DILUTION

     The purchase price of the Common Stock will be significantly greater than
the net tangible book value per share after giving effect to the Offering.
Investors in the Offering will incur an immediate and substantial dilution of
their investment of approximately $              in net tangible book value per
share of Common Stock.  See "Dilution" and the Company's Consolidated Financial
Statements and Notes thereto contained herein.

NO DIVIDENDS

     The Company has never declared or paid cash dividends on its capital stock
and does not anticipate paying any cash dividends in the foreseeable future.
The Company's current policy is to retain earnings, if any, to provide funds for
the operation and expansion of its business.  See "Dividend Policy".

<PAGE>
 
                                USE OF PROCEEDS

     The net proceeds to the Company from the sale of shares of Common Stock
offered hereby are estimated to be $          million after deducting the
estimated underwriting discounts and commissions and offering expenses payable
by the Company and assuming an initial public offering price of $
per share.

     The Company intends to use the net proceeds of the Offering to expand its
consumer business, including selling, advertising and headcount expenses,
introduce new business services, such as Internet access, hosting services,
value-added services and broadband services, and enter new markets, including
Spanish-speaking and Hispanic customers in the United States.  See "Risk Factors
- -- Risks of New Services and Markets; Failure to Implement Business Strategy".
Any remaining net proceeds from the Offering will be used for general corporate
purposes, including working capital. The amount actually expended by the Company
for the foregoing purposes will depend upon a number of factors, and the Company
reserves the right, in light of future developments and circumstances, to
allocate the proceeds to other uses or in a different manner.  See "Risk Factors
- -- Management Discretion Regarding Use of Proceeds". Pending the application of
the net proceeds from the Offering, the Company intends to invest such net
proceeds in short-term, investment grade, interest-bearing instruments.


                                DIVIDEND POLICY

     The Company has never declared or paid any cash dividends on its capital
stock and does not anticipate paying any cash dividends in the foreseeable
future.  The Company's current policy is to retain earnings, if any, to provide
funds for the operation and expansion of its business.  Payment of future
dividends, if any, will be at the discretion of the Company's Board of Directors
after taking into account various factors, including the Company's financial
condition, operating results, current and anticipated cash needs and growth
plans.  See "Risk Factors -- No Dividends" and "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources".

                                    DILUTION


   After giving effect to the conversion of the Contingent Notes into an
aggregate of               shares of Common Stock upon the closing of the
Offering (at an assumed initial public offering price of $               per
share) and the issuance after June 30, 1998 of 30,000,000 shares of Common Stock
for gross proceeds of $60,000,000, the net tangible book value of the Company as
of June 30, 1998 would have been $            , or $            per share of
Common Stock.  Net tangible book value per share is determined by dividing the
Company's tangible net worth (tangible assets less liabilities) by the number of
shares of Common Stock outstanding.  After giving effect to the sale of the
shares of Common Stock offered hereby at an assumed initial public offering
price of $             per share and after deducting the estimated underwriting
discounts and commissions and offering expenses payable by the Company, the pro
forma net tangible book value of the Company as of June 30, 1998 would have been
$           per share.  This represents an immediate increase in such net
tangible book value of $            per share to existing stockholders and an
immediate dilution of $               per share to new investors purchasing
shares in the Offering.  If the initial public offering price is higher or
lower, the dilution to the new investors will be greater or less, respectively.
The following table illustrates the per share dilution:

           SELECTED CONSOLIDATED FINANCIAL INFORMATION AND OTHER DATA

  The following tables set forth selected consolidated financial information and
other data for the Company and PSC.  The selected consolidated financial data
for the Company for the period from May 23, 1994 (date of inception) to December
31, 1994 and for the year ended December 31, 1995 has been derived from the
Company's Consolidated Financial Statements for the year ended December 31, 1995
appearing elsewhere in this Prospectus.  The selected consolidated financial
data for the Company for the years ended December 31, 1996 and 1997 and for PSC
for the year ended December 31, 1995, and for the period from January 1, 1996 to
June 16, 1996 has been derived from the Company's Consolidated Financial
Statements that appear elsewhere in this Prospectus, which have been audited by
PricewaterhouseCoopers LLP, independent public accountants.  The selected
consolidated financial and other data for the six month periods ended June 30,

adjustments) necessary for a fair representation of the information included
therein.  The results of operations for the six months ended June 30, 1998 are
not necessarily indicative of the results for the entire year or any other
future period.

(1) International Wireless Incorporated ("IW") was incorporated in May 1994 to
    evaluate and develop cellular telephone systems and Internet access and
    online services in Africa.  See "Corporate History and Certain Transactions
    -- Prior Corporate History".  In June 1996, the Company was formed under the
    name Prodigy, Inc. as a new holding company to acquire PSC and to hold IW
    and the other communications interests of IW.  On June 17, 1996, the Company
    consummated the acquisition of PSC. The acquisition was accounted for under
    the purchase method of accounting.  Accordingly, the results of operations
    of PSC are included in the Company's consolidated results of operations from
    the date of acquisition.  See Notes 1 and 4 to the Company's Consolidated
    Financial Statements. In January 1997, the Company's cellular telephone
    assets and operations were sold.  Subsequently, the Company decided to sell
    and wind-down its remaining international operations in Africa and China.
    See "Corporate History and Certain Transactions" and Note 5 to the Company's
    Consolidated Financial Statements.

(2) EBITDA is a standard measure commonly reported and widely used by analysts,
    investors and other interested parties for ISPs, and also provides
    additional information to assist investors in determining the Company's
    liquidity.  EBITDA is not an accounting measure under GAAP, is not
    necessarily indicative of operating income or cash flows from operations as
    determined under GAAP and may not be comparable to similarly titled measures
    reported by other companies.

(3) Reflects (i) the issuance after June 30, 1998 of 30,000,000 shares of Common
    Stock for gross proceeds of $60.0 million and (ii) the conversion upon the
    closing of the Offering (at an assumed initial public offering price of $
    per share) of the Contingent Notes held by IBM and Sears into an aggregate
    of        shares of Common Stock.  See "Corporate History and Certain
    Transactions -- Acquisition of Prodigy Services Company" and "-- Prior
    Equity Financing" and Note 9 to the Company's Consolidated Financial
    Statements.

(4) Adjusted to give effect to the sale by the Company of              shares of
    Common Stock offered hereby at an assumed public offering price of $
    per share and after deducting the estimated underwriting discounts and
    offering expenses payable by the Company.  See "Use of Proceeds".

    SEE "MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS -- PRO FORMA RESULTS OF OPERATIONS" FOR A PRESENTATION OF THE
UNAUDITED PRO FORMA RESULTS OF OPERATIONS AS IF THE ACQUISITION OF PSC HAD
OCCURRED AS OF JANUARY 1, 1995.  THE COMPANY BELIEVES THIS INFORMATION IS
IMPORTANT IN EVALUATING ITS FINANCIAL RESULTS OF OPERATIONS.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS

  The following discussion should be read in conjunction with "Risk Factors",
"Selected Consolidated Financial Information and Other Data" and the
Consolidated Financial Statements and Notes thereto contained herein.

OVERVIEW

  The Company is a leading national ISP.  In October 1996, the Company launched
Prodigy Internet, an open standards-based Internet access service.  Since the
autumn of 1997, the Company has focused on expanding the Prodigy Internet
subscriber base and introducing additional value-added services.  The Company
has also made strategic decisions to outsource its network, discontinue its
development of custom content and use multiple vendors for outsourced customer
service functions.  As a result of these initiatives, the Company has
substantially reduced its fixed operating costs and headcount.

  In conjunction with the launch of Prodigy Internet in October 1996, the
Company began offering a plan allowing subscribers unlimited usage of Prodigy
Internet for a flat monthly fee without hourly usage charges.  In December 1996,
the Company introduced a similar plan for Prodigy Classic.  Since the
introduction of the Company's unlimited usage plans, the portion of revenues
generated from hourly usage charges has decreased substantially.

  The results of operations of ISPs, including those of the Company, are
significantly affected by subscriber cancellations.  Subscriber acquisition
expenses and the administrative expenses of enrolling and assisting new
subscribers are substantial, and in the past the Company typically offered free
service for one or two months to new subscribers.  In many distribution
channels, the Company is replacing free trial programs with money-back
guarantees in order to attract enrollees who are less likely to terminate
service. The failure to attract and retain subscribers to the Company's
services, or an increase in the rate of subscriber cancellations, would have a
material adverse effect on the Company.  See "Risk Factors  -- Subscriber
Turnover".  The Company historically has experienced better retention for
subscribers under prepaid term plans than subscribers under month-to-month
plans.  Under prepaid term plans, subscribers choose to prepay for longer terms
at reduced monthly rates.  The Company ceased offering prepaid term plans in
1995 but reinstated such term plans in January 1997.

  The Company historically has experienced seasonality in its business, with
higher expenses during the last and first fiscal quarters, corresponding to the
Christmas and post-Christmas selling season, and lower timed usage revenues
during its second and third fiscal quarters resulting from reduced usage of its
services during the summer months.  The Company believes that the seasonal
reductions in timed usage revenues historically experienced by the Company will
be mitigated by the movement from timed usage plans to unlimited usage plans as
well as growth in the Company's subscriber base, although the Company expects to
continue to have higher expenses during its first and fourth quarters.  As a
result of the seasonality of its business, as well as other factors, the Company
experiences quarterly fluctuations in its operating results.  See "Risk Factors
- -- Quarterly Fluctuations in Operating Results".

  On June 17, 1996, the Company acquired PSC from IBM and Sears for an aggregate
purchase price of $78.1 million, consisting of a cash payment of $40.8 million,
the issuance of the Contingent Notes valued by an independent appraiser at $30.5
million and direct acquisition related expenses of $6.8 million.  See "Corporate
History and Certain Transactions -- Acquisition of Prodigy Services Company".
The Prodigy Acquisition was accounted for as a purchase.  Accordingly, the
assets purchased and liabilities assumed and related results of operations of
PSC are included in the consolidated financial statements of the Company from
the date of acquisition.  The purchase price was allocated among tangible and
intangible 

                                      28

assets acquired based on their respective fair market values. As part of this
process, the acquired technology was extensively evaluated, including the state
of the technology and needed developments, the inherent difficulties and
uncertainties in completing the development and thereby achieving technological
feasibility, and the risks related to the viability and potential changes to
target markets. Because the Internet technology acquired in the Prodigy
Acquisition was incomplete and substantial additional development effort by the
Company was required before a viable consumer product could be launched, the
Company recognized a charge for the purchase of incomplete technology in June
1996 in the amount of $46.1 million. See "-- Incomplete Technology" and Note 4
to the Company's Consolidated Financial Statements.

HISTORICAL RESULTS OF OPERATIONS

 SIX MONTHS ENDED JUNE 30, 1998 COMPARED TO SIX MONTHS ENDED JUNE 30, 1997

  The Company's total revenues have two components:  Internet revenues,
consisting of subscription revenues and transaction fees from Prodigy Internet
and Prodigy Classic, and other revenues, consisting primarily of advertising
fees.  The Company defines "billable" subscribers as subscribers who remain
enrolled beyond completion of the applicable trial or money-back guarantee
period.

  Revenues from Prodigy Internet increased $25.4 million, or 282%, from $9.0
million in the six months ended June 30, 1997 to $34.4 million in the six months
ended June 30, 1998.  The number of Prodigy Internet billable subscribers
increased from 160,000 at June 30, 1997 to 386,000 at June 30, 1998,
representing 23% and 61% of total billable subscribers at June 30, 1997 and June
30, 1998, respectively. Prodigy Internet subscribers accounted for 32% and 74%,
respectively, of total network usage during the six months ended June 30, 1997
and 1998, respectively.  Revenues from Prodigy Classic decreased from $56.5
million in the six months ended June 30, 1997 to $28.8 million in the six months
ended June 30, 1998 as the number of Prodigy Classic billable subscribers
decreased from 548,000 at June 30, 1997 to 252,000 at June 30, 1998.  See "Risk
Factors -- Migration from Prodigy Classic Service".  Total billable subscribers
decreased by 70,000, or 10%, from 708,000 at June 30, 1997 to 638,000 at June
30, 1998.  Timed usage revenues decreased $4.7 million, or 64%, from $7.3
million in the six months ended June 30, 1997 to $2.6 million in the six months
ended June 30, 1998.  The decrease in Internet revenues attributable to
decreases in the total number of billable subscribers and in timed usage
revenues associated with Prodigy Classic was offset, in part, by an increase in
average revenue per billable subscriber primarily due to the higher-priced plans
for unlimited usage associated with Prodigy Internet.  Other revenues increased
by $.1 million, or 3%, from $4.0 million in the six months ended June 30, 1997
to $4.1 million in the six months ended June 30, 1998.  As a result of the
foregoing factors, total revenues decreased by $2.2 million, or 3%, from $69.5
million in the six months ended June 30, 1997 to $67.3 million in the six months
ended June 30, 1998.

  Cost of revenues includes network and content expenses.  Cost of revenues
decreased from $61.8 million in the six months ended June 30, 1997 to $52.1
million in the six months ended June 30, 1998, a decrease of $9.7 million, or
16%.  This decrease was primarily attributable to reduced network rates incurred
by the Company in the six months ended June 30, 1998 due to its network
arrangements with Splitrock, which commenced in July 1997.  The effect of the
reduction in network rates was offset, in part, by an increase in total hours of
usage resulting from the shift of a substantial majority of the subscriber base
from timed usage to unlimited usage plans.  Content expense decreased as a
result of the renegotiation and/or termination of numerous content contracts
associated with Prodigy Classic and due to the Company's content outsourcing
agreement with Excite which substantially eliminated content expense associated
with Prodigy Internet beginning in April 1998.  See "Business -- Principal
Outsourcing Arrangements".

  Marketing expense includes the costs to acquire and retain subscribers,
advertising and other general sales and marketing costs.  Marketing expense
decreased from $21.5 million in the six months ended June 

                                      29
<PAGE>
 
30, 1997 to $15.5 million in the six months ended June 30, 1998. The 1997 period
reflected spending related to the launch of Prodigy Internet in October 1996,
which continued through the post-Christmas selling season. In addition, in early
1998, the Company temporarily deferred certain of its marketing programs in
response to network performance issues encountered during the initial roll-out
of the new Splitrock network. The Company expects that its marketing expenses
will increase during the balance of 1998 and 1999. See "Use of Proceeds".

  Product development expense includes research and development costs.  Product
development expense decreased from $10.0 million in the six months ended June
30, 1997 to $6.3 million in the six months ended June 30, 1998.  In the six
months ended June 30, 1997, product development activities were primarily
focused on the stabilization and enhancement of the Prodigy Internet platform
and on migration of Prodigy Classic content to the Prodigy Internet platform.
As a result of the completion of these activities in 1997, product development
activities and spending were subsequently reduced.  In the six months ended June
30, 1998, product development activities centered on integration and
stabilization of the Splitrock network, transition to the co-branded
Prodigy/Excite content platform for Prodigy Internet and development of certain
commercial applications and value-added services.

  General and administrative expense increased from $21.0 million in the six
months ended June 30, 1997 to $24.9 million in the six months ended June 30,
1998.  The increase in general and administrative expense was attributable to
the Company's international operations offset, in part, by significantly lower
personnel costs resulting from a decrease in average headcount and lower
incentive compensation expense, combined with lower occupancy expense due to the
relocation to a new headquarters facility as of January 1, 1998.  See "Business
- -- Facilities".

  Interest expense, net, decreased by $.6 million, or 60%, from $1.0 million in
the six months ended June 30, 1997 to $.4 million in the six months ended June
30, 1998, due to higher cash balances and reduced levels of borrowing.

  In the six months ended June 30, 1997, the Company recorded a loss of $2.3
million on an equity investment in a joint venture and a restructuring charge of
$4.7 million in connection with the sale of its network.  See "-- Restructuring
Charges" and "-- Former International Operations".

  As a result of the foregoing factors, the Company's net loss decreased from
$52.8 million in the six months ended June 30, 1997 to $31.9 million in the six
months ended June 30, 1998.

 YEARS ENDED DECEMBER 31, 1995, 1996 AND 1997

  Prior to the Prodigy Acquisition on June 17, 1996, the Company was a start-up
company engaged in the evaluation and development of cellular telephone systems
and Internet access and online services in Africa.  As a result of the
significant changes that occurred in the Company's business and operations as a
result of the Prodigy Acquisition, the subsequent sale and wind-down of the
Company's former international operations and other changes in the Company's
business model since the Prodigy Acquisition, the historical financial
statements of the Company are not directly comparable.  See "-- Pro Forma
Results of Operations".

  Total revenues increased from $12.2 thousand in 1995 to $98.9 million in 1996
and to $134.2 million in 1997.  Cost of revenue increased from $82.0 thousand in
1995 to $69.4 million in 1996 and to $98.8 million in 1997.  Marketing expense
increased from zero in 1995 to $21.3 million in 1996 and to $60.5 million in
1997.  Product development expense increased from zero in 1995 to $9.0 million
in 1996 and to $16.8 million in 1997.  General and administrative expense
increased from $3.0 million in 1995 to $52.3 million in 1996 and to $61.1
million in 1997.  In 1996, the Company recorded a charge of $46.1 million
relating to the purchase of incomplete technology acquired in the Prodigy
Acquisition, a $9.1 million write-down of its investment in Global Enterprise
Services, Inc. ("GES") to an estimated net realizable 

                                      30
<PAGE>
 
value of zero, restructuring and other special costs of $3.1 million, a loss of
$.5 million on an equity investment in a joint venture and interest expense, net
of $2.2 million. In 1997, the Company recorded a loss of $12.1 million on an
equity investment in a joint venture, restructuring and other special costs of
$9.9 million, a $2.4 million write-down of its investment in its African
Internet operations to the estimated net realizable value, a $.8 million loss on
the sale of its African cellular telephone operations and interest expense, net
of $1.4 million. See "-- Restructuring Charges", "-- Incomplete Technology" and
"--Dispositions of Former International Operations". As a result of the
foregoing factors, the Company's net loss increased from $3.1 million in 1995 to
$114.1 million in 1996 and to $129.3 million in 1997. The foregoing changes in
the Company's operating results resulted primarily from the Prodigy Acquisition
on June 17, 1996 and the inclusion of the operating results of PSC's business
for six and one-half months in 1996 and all of 1997.

PRO FORMA RESULTS OF OPERATIONS

  IW was incorporated in May 1994 to evaluate and develop cellular telephone
systems in Africa.  In June 1996, the Company was formed as a new holding
company to acquire PSC and to hold IW and the other communications interests of
IW.  All outstanding common stock of IW was converted into Common Stock of the
Company on a one-for-one basis and the assets and liabilities of IW were carried
over to the Company at historical cost. On June 17, 1996, the Company
consummated the Prodigy Acquisition.  The Prodigy Acquisition was accounted for
under the purchase method of accounting.  Accordingly, the results of operations
of PSC since the date of acquisition are included in the Company's results of
operations. Subsequently, the Company determined to sell and wind-down its
international operations in Africa and China.  See "-- Dispositions of Former
International Operations", "Corporate History and Certain Transactions -- Prior
Corporate History" and Notes 1, 4 and 5 to the Company's Consolidated Financial
Statements.  Since the autumn of 1997, the Company has focused on expanding
Prodigy Internet's subscriber base and introducing additional value-added
services.  The Company also made strategic decisions to outsource its network,
discontinue its development of custom content and use multiple vendors for
outsourced customer service functions.  As a result of these initiatives, the
Company has substantially reduced its fixed operating costs and headcount.

  As a result of the significant changes that occurred in the Company's business
and operations as a result of the Prodigy Acquisition, the subsequent sale and
wind-down of the Company's former international operations and other changes in
the Company's business model since the Prodigy Acquisition, the historical
financial statements of the Company are not directly comparable.  The following
table presents the Company's pro forma results of operations for the years ended
December 31, 1995 and 1996 as if the Prodigy Acquisition had occurred on January
1, 1995.  The aggregate purchase price of $78.1 million consisted of a cash
payment of $40.8 million, the issuance of the Contingent Notes valued at $30.5
million and acquisition related expenses of $6.8 million.  Such purchase price
was allocated to the assets acquired and liabilities assumed based on their
respective fair market values as of the date of acquisition. A significant
portion of the purchase price was allocated to intangible assets, including
approximately $46.1 million to acquired incomplete technology which was
immediately expensed.  See Note 4 to the Company's Consolidated Financial
Statements.  Although such pro forma presentation is not required by generally
accepted accounting principals, the pro forma data is presented herein because
the Company believes this information presents the most meaningful basis for
comparing the Company's result of operations in view of the significant change
in its business resulting from the Prodigy Acquisition.  The accompanying pro
forma information is presented for illustrative purposes only and is not
necessarily indicative of the results of operations that would have occurred if
the Prodigy Acquisition had been consummated as of January 1, 1995, nor is it
intended to indicate the Company's financial condition or results of operations
for any future date or period.  The pro forma adjustments are described in the
Notes to the table below.  No adjustments have been made to the pro forma data
for the subsequent sale and wind-down of the Company's former international
operations.

</TABLE>

    The following pro forma adjustments have been made:

(1) Reduced depreciation expense of $8.3 million and $4.2 million in 1995 and
    1996, respectively, as a result of the fair valuation of the assets acquired
    in the Prodigy Acquisition.  Such depreciation expense reduction is
    reflected in costs of revenue ($6.2 million and $3.1 million, respectively)
    and general and administrative expenses ($2.1 million and $1.1 million,
    respectively).

(2) Additional amortization expense of $3.0 million and $1.4 million in 1995 and
    1996, respectively, on intangible assets acquired in the Prodigy Acquisition
    amortized over the estimated life of 10 years.  Such amortization expense is
    reflected in general and administrative expenses.

(3) Reduced amortization expense of $2.0 million and $.9 in 1995 and 1996,
    respectively, relating to unfavorable lease agreements recognized at the
    time of the acquisition, over the lease term to reflect a full year's
    credit.  Such amortization expense reduction is reflected in general and
    administrative expenses.

(4) The elimination of non-recurring acquired incomplete technology of $46.1
    million in 1996.

(5) Increased interest expense of $4.4 million and $2.0 million in 1995 and
    1996, respectively, on additional borrowings to finance the acquisition, at
    an assumed interest rate of 8.75% per annum.

 YEAR ENDED DECEMBER 31, 1997 COMPARED TO PRO FORMA YEAR ENDED DECEMBER 31, 1996

  The Prodigy Internet service was launched in October 1996 but did not generate
any significant revenues during 1996.  During 1997, Prodigy Internet grew from
7,000 billable subscribers at December 31, 1996 to 221,000 billable subscribers
at December 31, 1997, and generated revenues of $29.6 million.  Total revenues
decreased by $71.8 million, or 35%, from $206.0 million in 1996 to $134.2
million in 1997, primarily due to a decrease in Prodigy Classic billable
subscribers from 807,000 at December 31, 1996 to 394,000 at December 31, 1997.
Prodigy Classic revenues declined from $188.8 million in 1996 to $98.7 million
in 1997, representing 92% and 74%, respectively, of total revenues.  In
conjunction with the launch of Prodigy Internet in October 1996, there commenced
a shift in subscriber composition from timed usage plans to higher-priced
unlimited usage plans.  As a result, timed usage revenues decreased from $40.2
million in 1996 to $12.0 million in 1997, a decrease of $28.2 million, or 70%.
Other revenues decreased from $17.1 million in 1996 to $5.9 million in 1997, a
decrease of $11.2 million, or 65%, primarily attributable to decreases in
subscribers and advertisers and reduced advertising display fees from Prodigy
Classic.

  Cost of revenues decreased from $134.1 million in 1996 to $98.8 million in
1997, a decrease of $35.3 million, or 26%, primarily due to network rate
reductions resulting from the Company's network arrangements with Splitrock
which commenced in July 1997, lower subscriber levels, headcount reductions in
the content area, reductions in royalty-based content in 1997, the renegotiation
and/or termination of certain Prodigy Classic content contracts and the
elimination of certain proprietary Internet content early in 1997.

  Marketing expense decreased from $64.8 million in 1996 to $60.5 million in
1997, a decrease of $4.3 million, or 7%.  In 1996, marketing expense reflected,
in part, a special marketing program which the Company implemented during the
1995-1996 selling season and additional advertising campaigns instituted in late
1996 to support the launch of Prodigy Internet.  Prodigy Internet launch
advertising continued into 1997.

  Product development expense decreased from $20.3 million in 1996 to $16.8
million in 1997, a decrease of $3.5 million, or 17%.  The Company's product
development efforts during 1996 were focused on the design and development of
Prodigy Internet, which was essentially completed by the end of 1996.  During
1997, product development efforts primarily related to the stabilization and
enhancement of Prodigy Internet, which required fewer resources than in the
prior year, and integration and stabilization of the Splitrock network.

  General and administrative expense decreased from $84.6 million in 1996 to
$61.1 million in 1997, a decrease of $23.5 million, or 28%.  The decrease in
general and administrative expense was primarily due to lower personnel costs
resulting from decreased headcount and incentive compensation expense, a
reduction in occupancy expense and a cost containment program initiated in the
customer service area.

  Interest expense, net decreased from $4.2 million in 1996 to $1.4 million in
1997, a decrease of $2.8 million, or 67%.  This decrease resulted from reduced
levels of borrowing.

  In 1996, the Company recorded a $9.1 million write-down of its investment in
GES to an estimated net realizable value of zero, restructuring and other
special costs of $17.6 million and a loss of $.5 million on an equity investment
in a joint venture.  In 1997, the Company recorded a loss of $12.1 million on an
equity investment in a joint venture, restructuring and other special costs of
$9.9 million, a $2.4 million write-down of its investment in its African
Internet operations to the estimated net realizable value, a $.8 million loss on
the sale of its African cellular telephone operations and a recovery on equity
investment 

                                      33
<PAGE>
 
of $.3 million on the sale of its interest in GES. See "--Restructuring Charges"
and "-- Former International Operations".

  As a result of the foregoing factors, the Company's net loss increased from
$129.2 million in 1996 to $129.3 million in 1997.

 PRO FORMA YEAR ENDED DECEMBER 31, 1996 COMPARED TO PRO FORMA YEAR ENDED
DECEMBER 31, 1995

  Total revenues decreased from $243.4 million in 1995 to $206.0 million in
1996, a decrease of $37.4 million, or 15%.  Internet and online service revenues
declined from $230.6 million in 1995 to $188.9 million in 1996, a decrease of
$41.7 million, or 18%, primarily due to a decrease in total billable subscribers
from 1,133,000 at December 31, 1995 to 814,000 at December 31, 1996.  Timed
usage revenues decreased from $42.8 million in 1995 to $40.2 million in 1996, a
decrease of $2.6 million, or 6%.  All Internet and online service revenues in
1995 and substantially all Internet and online service revenues in 1996 were
attributable to Prodigy Classic.  Other revenues increased from $12.8 million in
1995 to $17.1 million in 1996, an increase of $4.3 million, or 34%, primarily
due to revenues from the Company's international operations.

  Cost of revenues increased from $114.3 million in 1995 to $134.1 million in
1996, an increase of $19.8 million, or 17%, primarily due to increases in
personnel and content expense as well as increased costs of the Company's
international operations.

  Marketing expense decreased from $67.4 million in 1995 to $64.8 million in
1996, a decrease of $2.6 million, or 4%.  Marketing expense increased as a
percentage of revenues from 28% to 31%, primarily due to marketing campaigns in
support of the launch of Prodigy Internet in October 1996.

  Product development expense decreased from $22.6 million in 1995 to $20.3
million in 1996, a decrease of $2.3 million, or 10%.  In 1996, the Company
incurred product development costs for the design and development of the Prodigy
Internet platform, which were more than offset by the reduction in development
costs for Prodigy Classic.

  General and administrative expense increased from $70.6 million in 1995 to
$84.6 million in 1996, an increase of $14.0 million, or 20%, primarily due to
costs incurred in connection with a new subscriber management system, increased
occupancy expense and increased costs of the Company's international operations.

  Interest expense, net increased from $3.3 million in 1995 to $4.2 million in
1996, an increase of $.9 million, or 27%, primarily due to lower cash balances
and higher borrowings.

  In 1996, the Company recorded a $9.1 million write-down of its investment in
GES to an estimated net realizable value of zero, restructuring and other
special costs of $17.6 million and a loss of $.5 million on an equity investment
in a joint venture.  See "-- Restructuring Charges" and "-- Former International
Operations".

  As a result of the foregoing factors, the Company's net loss increased from
$34.8 million in 1995 to $129.2 million in 1996, an increase of $94.4 million.

___________________________

(1) Opening balance represents the remaining balance of prior restructuring
    charges recorded by PSC and assumed by the Company at the time of the
    Prodigy Acquisition.  Restructuring charges of $14.6 million were recorded
    by PSC in 1996 prior to the time of the Prodigy Acquisition.  These
    restructuring charges included lease termination penalties and write-down of
    leasehold improvements at PSC's former headquarters' location as well as
    severance pay, early retirements and outplacement services in a reduction-
    in-force which affected 120 employees.

(2) In connection with the sale of its network, the Company incurred liabilities
    related primarily to early termination payments and other contractual
    obligations for certain non-cancelable network related agreements.

                                      35
<PAGE>
 
(3) The Company implemented restructuring plans in 1996 and 1997 intended to
    reduce costs through a reduction-in-force.  Approximately 120 employees and
    80 employees throughout the Company were terminated, respectively, in 1996
    and 1997.

(4) The Company decided to discontinue the production of its own content and as
    a result recorded a charge of $.6 million to account for the employee
    termination costs and the costs to settle content related contractual
    obligations.  Approximately 25 employees were terminated.

(5) The Company's offices in Massachusetts were closed and a charge of $1.6
    million was recorded to account for the costs of employee terminations and
    lease cancellation. The terminated employees were involved with the
    Company's international operations and/or former headquarters management.
    Approximately 20 employees were terminated.

(6) Beginning in late 1996, the Company vacated 29% of its leased space at its
    former headquarters location.  The cost of the lease attributed to the idle
    leased facility amounted to $2.5 million.  The Company terminated its lease
    at this location and moved to a new facility effective January 1, 1998.

INCOMPLETE TECHNOLOGY

    The Prodigy Acquisition was accounted for as a purchase.  Accordingly, the
purchase price was allocated among tangible and intangible assets based on their
respective fair market values.  The fair value of intangible assets was
determined using a risk adjusted discounted cash flow approach.  Specifically,
the Internet technology acquired was evaluated through extensive interviews and
analysis of data concerning the state of the technology and required development
work.  The evaluation of the underlying technology acquired considered the
inherent difficulties and uncertainties in completing the development and
thereby achieving technological feasibility, the risks related to the viability
and potential changes to target markets.  The technology had no alternative
future use to the Company, inasmuch as the Company could not commercialize the
technology in its existing form.  The Company also had no other product, line of
business or research and development in which the technology could be utilized.
Therefore, the Company recognized a $46.1 million charge in 1996 for the
purchase of incomplete technology.

    The purchased technology was incomplete because the majority of the coding,
integration and testing of the product was incomplete.  At the date of the
Prodigy Acquisition (June 17, 1996), there were over 50 components that needed
further development and integration before the Prodigy Internet service could
reach technological feasibility.  These components included applications for
parental access control, browsing, searching, e-mail, the message board, menus,
the navigational bar, the tool bar, code update mechanisms, authentication,
registration, service access control and subscriber billing.  The ability of the
Company's Prodigy Internet development team to integrate these components into
the Prodigy Internet platform was a crucial factor in reaching technological
feasibility, and the ability to complete this integration had not been
established as of the acquisition date.  The Company has now successfully
completed the further development necessary to complete and integrate the
acquired technology.

FORMER INTERNATIONAL OPERATIONS

    The historical and pro forma results discussed above include the operating
results of the Company's Africa and China operations, which began in late-1995
and mid-1996, respectively.  The revenue and net loss from the Company's Africa
and China operations were $7.0 thousand and $89.0 thousand, respectively, for
the year ended December 31, 1995, $1.0 million and $2.7 million, respectively,
for the year ended December 31, 1996, $3.2 million and $8.5 million,
respectively, for the year ended December 31, 1997, $2.8 million and $4.0
million, respectively, for the six months ended June 30, 1997 and $2.8 million
and $1.7 million, respectively, for six months ended June 30, 1998.  The Company
sold its African cellular telephone operations in January 1997, determined to
terminate its Chinese operations in December 1997 and agreed to sell its African
Internet operations in September 1998. In 1997, the Company recorded a $.8
million loss on the sale of its African cellular telephone operations and a $2.4
million write-down of its 

                                      36
<PAGE>
 
investment in its African Internet operations to the estimated net realizable
value. See "Corporate History and Certain Transactions -- Prior Corporate
History".

LIQUIDITY AND CAPITAL RESOURCES

   Since formation, the Company has relied on private sales of equity securities
(totaling $277.3 million through August 31, 1998) and borrowings to fund its
operations.  See "Corporate History and Certain Transactions -- Prior Equity
Financings."  The Company has incurred significant losses since inception and,
at June 30, 1998, had an accumulated deficit of $279.3 million and a
stockholders' deficit of $18.3 million.  For the years ended December 31, 1995,
1996 and 1997 and the six months ended June 30, 1997 and 1998, respectively, the
Company incurred negative cash flow from operations of $2.4 million, $35.3
million, $114.0 million, $56.4 million and $34.8 million.  Prior to its
acquisition by the Company, PSC sustained losses and negative cash flow from
operations which required continued funding by PSC's former owners, IBM and
Sears, aggregating $1.3 billion as of June 16, 1996 (the day before the Prodigy
Acquisition).  See "Risk Factors -- History of Losses".

   In August 1998, Carso Global Telecom agreed to provide the Company with a
$35.6 million committed revolving line of credit entitling the Company to
borrow, repay and reborrow amounts in minimum increments of $1.0 million prior
to maturity on December 31, 1999.  Advances are due 90 days after borrowing, but
the Company is permitted to roll over advances into new advances at its
election. Advances are unsecured and bear interest at the LIBOR rate plus
between one and five percentage points (as negotiated on a case-by-case basis).
As of August 31, 1998, no amounts were outstanding under the revolving line of
credit.  Carso Global Telecom is the Company's principal stockholder.  See
"Principal Stockholders".

   As a result of the Company's outsourcing arrangements, the Company has
significantly reduced the level of capital expenditures needed in its
operations.  The Company's July 1997 network agreement with Splitrock eliminated
the need for the Company to maintain and upgrade its own network.  The Company's
portal content agreement with Excite eliminated the need, beginning in April
1998, for internal development of content and Prodigy Internet customization and
other programming projects.  See "Business -- Principal Outsourcing
Arrangements".  The Company's capital expenditures for the six months ended June
30, 1998 were $.3 million, primarily for the purchase of data processing
equipment, compared to $1.4 million, $8.8 million and $8.6 million,
respectively, for the years ended December 31, 1995, 1996 and 1997.  The Company
currently anticipates that its capital expenditures for the period July 1, 1998
through December 31, 1999 will be approximately $14.0 million, principally for
the purchase of new equipment for Prodigy Internet.

   At August 31, 1998, the Company had cash of $35.0 million, of which $4.1
million secured a letter of credit and was thus unavailable.  The Company is
currently experiencing substantial negative cash flow each month and expects to
continue to experience negative cash flow through at least the end of 1999. The
Company's future financing requirements will depend on a number of factors,
including the Company's operating performance and increases in operating
expenses associated with growth in the Company's business.  Based on its current
operating plan, the Company believes that the net proceeds from the Offering,
together with its existing cash and available financing under its revolving
credit facility with Carso Global Telecom, will be sufficient to meet its
anticipated cash requirements for at least the next twelve months.  The Company
has made no arrangements to obtain additional financing, other than pursuant to
the Carso Global Telecom credit facility, and there can be no assurance that
adequate additional financing on acceptable terms will be available when needed,
if at all. The unavailability of sufficient financing when needed would have a
material adverse effect on the Company.  See "Risk Factors -- Need for
Additional Financing".

   In August 1998, Telmex purchased 24,500,000 shares of Common Stock from the
Company for gross proceeds of $49.0 million, and in July 1998 Carso Global
Telecom purchased 5,500,000 shares of Common Stock from the Company for gross
proceeds of $11.0 million.  The Company used a portion of the proceeds to repay
amounts owed to Banco Inbursa and Bank of America in the aggregate amount of
$32.1 million.  See "Corporate History and Certain Transactions" and "Principal
Stockholders".

YEAR 2000 COMPLIANCE

   The Year 2000 issue is the result of computer programs being written using
two digits (rather than four) to define the applicable year.  Computer programs
that have time-sensitive software may recognize a date using "00" as the year
1900 rather than the year 2000.  This could result in a system failure or
miscalculations causing disruptions of operations, including among other things,
a temporary inability to process transactions, send invoices or engage in other
normal business activities.  The Company maintains various internal computer
systems and equipment and contracts with third-party vendors for the provision
of computerized customer billing, network operation, Prodigy Internet service
content and certain other information technology and other services.

   The Company is currently incurring costs to resolve the potential impact of
the year 2000 on the processing of date-sensitive information by the Company's
internal computer systems and equipment and the computer systems and equipment
of the third-party vendors on which the Company's business relies. The Company
has established a Year 2000 project office staffed by Company personnel and
assisted by a consulting firm.

   The Company has completed an inventory of substantially all of its internal
systems and programs related to both the delivery of the Prodigy Internet
service and the daily operations of the business.  Based on its preliminary
analysis, the Company estimates that it will spend approximately $3.5 million
through the end of 1999 to remediate potential Year 2000 problems with its
internal systems.

   The Company is developing contingency plans in the event that any critical
service component or business process fails due to a Year 2000 problem. The
Company expects to complete contingency planning by mid-1999. With respect to
critical third-party vendor systems, Splitrock has publicly reported that its
network services will be Year 2000 compliant, Excite has publicly reported that
there are no significant Year 2000 issues within its systems or services, and
Prodigy's billing provider has committed to making its billing system Year 2000
compliant.  There can be no assurance that the Company will be able to address,
in a timely fashion, all potential Year 2000 problems, or that the systems of
the third-party vendors upon which the Company's business relies (and the
maintenance and operation of which are not within the control of the Company)
will be Year 2000 compliant or will become Year 2000 compliant in a timely
manner.  Any Year 2000 problems could impact the provision of products or
services to the Company's customers and could subject the Company to the risk of
litigation, lost revenues and loss of current or future customers.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

   In June 1997, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 131, "Disclosures about Segments of an Enterprise and Related Information"
("SFAS 131"), effective for years beginning after December 15, 1997.  SFAS 131
requires that a company report financial and descriptive information about its
reportable operating segments pursuant to criteria that differ from current
accounting practice. Operating segments, as defined, are components of an
enterprise about which separate financial information is available that is
evaluated regularly by the chief operating decision maker in deciding how to
allocate resources and in assessing performance.  The financial information to
be reported includes segment profit or loss, certain revenue and expense items
and segment assets and reconciliations to corresponding amounts in the general
purpose financial statements.  SFAS 131 also requires revenues from 

                                      38
<PAGE>
 
products or services, countries where the company has operations or assets and
major customers to be reported. The Company does not believe implementation of
SFAS 131 will have a material impact on its consolidated financial statements.

   In March 1998, the Accounting Standards Executive Committee ("AcSEC") issued
Statement of Position No. 98-1, "Accounting for the Cost of Computer Software
Developed or Obtained for Internal Use" ("SOP 98-1"), which provides guidance on
applying generally accepted accounting principles in addressing whether and
under what condition the costs of internal-use software should be capitalized.
SOP 98-1 is effective for transactions entered into in fiscal years beginning
after December 15, 1998, but earlier  adoption is encouraged.  The Company
adopted the guidelines of SOP 98-1 as of January 1, 1998. Adoption of SOP 98-1
did not have a material impact on the Company's consolidated financial
statements.

   In April 1998, the AcSEC issued Statement of Position No. 98-5, "Reporting on
the Costs of Start-Up Activities" ("SOP 98-5"), effective for fiscal years
beginning after December 15, 1998.  SOP 98-5 provides guidance on the financial
reporting of start-up costs and organization costs.  SOP 98-5 requires that
costs of start-up activities and organization costs be expensed as incurred.
Initial application of SOP 98-5 should be reported as the cumulative effect of a
change in accounting principles, as described in Accounting Principles Board
(APB) Opinion No. 20, "Accounting Changes".  When adopting SOP 98-5, entities
are not required to report the pro forma effects of retroactive application.
The Company does not believe implementation of SOP 98-5 will have a material
impact on its consolidated financial statements.

                                    BUSINESS

   Prodigy is a leading nationwide ISP that provides fast and reliable Internet
access and related value-added services.  Prodigy has nationwide brand
recognition and customer acquisition channels not available to regional and
local ISPs, and utilizes a nationwide network covering approximately 600 cities
in all 50 states allowing approximately 83% of the United States population to
access Prodigy's services with a local telephone call.  Combining these
strengths with Prodigy's scalable technology has enabled the Prodigy Internet
service to achieve one of the fastest subscriber growth rates among U.S. ISPs,
with the number of billable subscribers increasing from 221,000 at December 31,
1997 to 386,000 at June 30, 1998.  Prodigy Internet enables the Internet to be
used as a productivity tool by allowing subscribers to obtain and communicate
desired information quickly and efficiently in an easy and personalized manner.
Prodigy Internet users receive fast and reliable access to the Internet,
Prodigy-branded content powered by Excite and other Prodigy member services.
Prodigy is in the process of expanding its Web hosting and electronic commerce
activities for business customers, and believes that its extensive experience in
operating a large data center with electronic commerce applications positions it
well for growth in these areas.  Prodigy is also in the process of evaluating
and introducing other consumer value-added services, such as the co-branded
marketing of paging, long-distance and cellular telephone services, Internet-
based telephony and fax services and online bill presentment.

   Prodigy has been an online pioneer since its inception in 1984.  Prodigy's
original online service, now called Prodigy Classic, was launched as the world's
first consumer-focused online service in 1988 and achieved national distribution
in 1990.  Prodigy Classic featured custom content, e-mail and chat capabilities
and was based on proprietary technologies.  In October 1996, the Company
launched Prodigy Internet, an open standards-based Internet access service.
Since the autumn of 1997, the Company has focused on expanding Prodigy
Internet's subscriber base and introducing additional value-added services. The
Company has also made strategic decisions to outsource its network, discontinue
its development of custom content and use multiple vendors for outsourced
customer service functions.  As a result of these initiatives, the Company has
substantially reduced its fixed operating costs and headcount and now has a
business and operating model that it believes can accommodate sustained
subscriber growth on a cost-effective basis without significant capital
expenditures.

INDUSTRY BACKGROUND

 GROWTH OF THE INTERNET AND ELECTRONIC COMMERCE

   The Internet is a collection of computer networks that links millions of
public and private computers to form the largest computer network in the world.
It has become an important global medium enabling millions of people to obtain
and share information and conduct business electronically, and a critical tool
for information and communications for many users.  The Internet has grown
rapidly in recent years both in terms of the number of Web users and the number
of Web sites.  IDC estimates that at the end of 1997 there were over 38 million
Web users in the United States and over 68 million worldwide, and projects that
by the end of 2002 the number of Web users will increase to over 135 million in
the United States and over 319 million worldwide.  The growth in the number of
Web users and the number of Web sites is being driven by a number of factors,
including the large and growing installed base of personal computers, advances
in the performance and speed of personal computers and modems, improvements in
network infrastructure, easier access to the Internet and the increasing
importance of the Internet as a communications medium, an information resource
and a sales and distribution channel.

   For many businesses, the Internet has created a new communications and sales
channel enabling large numbers of geographically dispersed organizations and
consumers to be reached quickly and cost-effectively.  IDC estimates that the
number of consumers buying goods and services on the Internet will grow from
17.6 million in 1997 to 128.4 million in 2002, and that the total value of goods
and services 

                                      40
<PAGE>
 
purchased over the Internet will increase from approximately $12 billion in 1997
to approximately $426 billion by 2002.

 EVOLUTION OF THE INTERNET SERVICES MARKET

   Today, the Internet services market consists primarily of Internet access.
Access services include dial-up access for individuals and small businesses and
high-speed dedicated access primarily for larger organizations.  Forrester
projects that revenues from Internet access services in the United States will
grow from $5.8 billion in 1997 to $38.1 billion in 2002.  The rapid development
and growth of the Internet has resulted in a highly fragmented industry,
consisting of more than 4,000 ISPs in the United States, most of which operate
as small, local businesses.  The Internet services industry is expected to
undergo substantial consolidation, especially among mid-sized ISPs, over the
next few years.  ISPs vary widely in geographic coverage, customer focus and the
nature and quality of services provided to subscribers. Relatively few ISPs
offer nationwide coverage, have a brand name with nationwide recognition or have
the ability to grow significantly without additional investment in
infrastructure.  ISPs may concentrate on specific types of customers that differ
from the target markets of other ISPs.  Services offered by ISPs can range from
simple dial-up access to highly organized, personalized access coupled with
value-added services.  The Company believes that consumers are generally focused
on speed and reliability of access, ease of use, customer service and price as
they evaluate an ISP.  In addition to speed and reliability of access, the
Company believes many business customers want all their Internet-based
requirements, such as access, Web hosting and electronic commerce applications,
met by a single provider.

   Internet operations, including Web hosting and electronic commerce, are
increasingly becoming mission-critical to an enterprise's commercial and
communications operations.  However, many businesses lack the resources and
expertise to develop, maintain and enhance, on a cost-effective basis, the
facilities and network systems necessary for successful Internet operations.  As
a result, businesses increasingly seek outsourcing arrangements to enhance Web
site reliability and performance, provide continuous operation of their Internet
solutions and reduce related operating expenses.  By outsourcing these services,
companies can focus on their core competencies rather than utilizing their
resources to support Internet operations.  Forrester projects that Internet
hosting revenues will increase from approximately $400 million in 1997 to $10.5
billion in 2002.

   As a result, there is increasing demand for ISPs to offer "turnkey"
electronic commerce services.  An increasing number of ISPs are beginning to
supplement their basic Internet access services with a variety of commercial
services that facilitate electronic commerce, such as Web hosting, bill
presentment, co-location and other value-added services.  Such services expand
an ISP's potential revenue streams from basic monthly access fees to other fees
such as set-up and maintenance charges.  In addition to services that enable
electronic commerce, a few larger and more sophisticated ISPs are beginning to
market other value-added services, such as paging, long-distance and cellular
telephone services, to both consumers and business customers nationwide.

THE PRODIGY SOLUTION

   The Company currently provides fast and reliable Internet access and certain
value-added services. The Company intends to meet the rapidly changing needs of
its customers by offering new products and additional value-added services as
demand arises.  The Company believes the following competitive strengths will
position Prodigy to meet this goal:

   NATIONWIDE BRAND NAME RECOGNITION.  Since the introduction of its original
service in 1988, Prodigy has established substantial nationwide brand
recognition that the Company believes offers a significant competitive advantage
in attracting new subscribers to its services.  The Company uses a variety of
advertising, promotional and distribution channels to leverage the equity of its
brand name, one of the 


                                      41
<PAGE>
 
oldest and best-known in the Internet industry. The Company launched the Prodigy
Internet service in October 1996 as a productivity tool dedicated to the
Internet and designed to make a user's experience simpler and more rewarding.
The Company believes the strength of the Prodigy brand has enhanced the market
positioning of Prodigy Internet and facilitated the rapid growth in the number
of Prodigy Internet subscribers.

   NATIONWIDE CUSTOMER ACQUISITION CHANNELS.  The Company has in place a variety
of nationwide customer acquisition channels, including:  bundling with PCs
shipped by leading PC manufacturers; the Microsoft relationship described below;
Web-based marketing; retail channels; direct mail and telemarketing; and
migration of subscribers from Prodigy Classic to Prodigy Internet.  Many of
Prodigy's customer acquisition channels are not available to regional and local
ISPs who lack the required nationwide presence.  The Prodigy Internet software
is pre-loaded on the hard drives of selected PC models shipped by many leading
PC manufacturers and is included in the online services folder of every copy of
the Windows 98 and Windows 95 (OSR 2.5 release) operating systems shipped by
Microsoft for sale in retail channels or for loading on new PCs.  See "--
Customer Acquisition and Marketing".

   SCALABLE BUSINESS MODEL.  Over the past 12 months, Prodigy has created a
business and operating model that it believes can accommodate sustained
subscriber growth on a cost-effective basis without significant capital
expenditures.  Prodigy has outsourced the major capital and labor intensive
functions to organizations that can provide scalable and dependable network
coverage, customer service and organized content.  Prodigy's outsourcing
arrangements enable it to rely on the resources of other organizations while
drawing on its own past experience to manage these services.  As a result, the
principal costs of servicing new subscribers, network usage and telephone
customer service, are variable and generally increase only as the subscriber
base increases.  In addition, Prodigy's e-mail and customer authentication
systems have been developed in-house to support a large number of customers, and
Prodigy's existing data hosting facilities have the capacity to support millions
of additional subscribers. See "Business".

   FAST AND RELIABLE SERVICE.  The Prodigy Internet service offers fast and
reliable Internet connections. Prodigy Internet subscribers have direct Internet
access at speeds of up to 56 kbps (kilobits per second). Inverse Network
Technology Inc. ("Inverse") is an independent Internet testing group that
measures and reports eight parameters of ISP network performance.  Since
completion of the network used by the Company in May 1998, Inverse has given
Prodigy Internet ratings of A+ or A for 24-hour call failure rate for each of
the months of May, June, July and August 1998, which ratings in each case
exceeded or equalled the comparable overall industry rating given by Inverse
based on 13 major providers of Internet access services.  The Company believes
call failure rate is the most important network measure in terms of customer
satisfaction.  Overall, Prodigy Internet exceeded or equalled the comparable
industry rating given by Inverse in at least seven of the eight parameters for
each of the months of May, June, July and August 1998.  For a fuller discussion
of network performance and the Inverse reports, see "-- Network and Related
Infrastructure -- Reliability and Availability".

   NATIONWIDE NETWORK COVERAGE.  The network used to offer the Prodigy Internet
service covers approximately 600 cities in all 50 states.  The network is able
to provide dial-up access, with a local telephone call, to approximately 83% of
the households in the United States.  Prodigy also offers network access via an
800 telephone number for $.10 per minute without an additional enrollment
charge.  See "-- Network and Related Infrastructure".

   SUPERIOR CUSTOMER EXPERIENCE.  In addition to offering an easy-to-use
interface and extensive personalization, the Company believes Prodigy Internet
offers a productive and rewarding customer experience.  The Company's customer
services include toll-free telephone support, various online support options and
an online "members helping members" program.  The Company distributes its
customer service calls over multiple outsourcing partners to reduce call waiting
times.  The Company has developed 

                                       42
<PAGE>
 
proprietary filters to limit unsolicited commercial e-mail, or "spam", sent by
or received by subscribers. The Company accepts banner advertisements and
sponsorships but limits pop-up advertisements and intercept screens so that the
revenue opportunity from advertising is balanced against an enhanced customer
experience. The Company also offers the Prodigy Value Center, which rewards
subscribers for their loyalty. See "--Products and Services".

BUSINESS STRATEGY

   Prodigy's objectives are to strengthen its position as a leading nationwide
ISP and to expand the range of services it offers and markets it serves.  See
"Risk Factors -- Risks of New Services and Markets; Failure to Implement
Business Strategy".  Key elements to the Company's business strategy include:

   LEVERAGE STRONG BRAND NAME.  The Company intends to increase its brand equity
by promoting the recognition and positive perceptions of the Prodigy brand,
partly through increased marketing and advertising activities.  See "Use of
Proceeds".  The Company is leveraging the Prodigy brand name to encourage
Prodigy Classic subscribers to migrate to Prodigy Internet, expand its other
customer acquisition activities, offer new services and enter new markets.

   INTRODUCE NEW SERVICES.  The Company is seeking to expand its Web hosting
business and introduce additional value-added services.  The Company's strategy
is to introduce value-added services for business customers that will also be
attractive to consumers.  For example, in September 1998 the Company launched
co-branded paging services in partnership with SkyTel Communications, Inc.
("SkyTel").  The Company is also pursuing a variety of other value-added
services, such as the co-branded marketing of long-distance and cellular
telephone services, Internet-based telephony and fax services and online bill
presentment.  The Company is enhancing its data mining capabilities to enable
targeted sales and marketing of value-added services to existing subscribers.
In addition, the Company plans to expand its electronic commerce activities and
introduce broadband services.  Prodigy already provides the fundamental elements
of electronic commerce, and Prodigy's strategy is to provide turnkey solutions
for electronic commerce.  Prodigy's broadband strategy is designed to provide
business customers with a suite of Internet access and value-added services.
See "-- Products and Services".

   ENTER NEW MARKETS.  The Company intends to leverage its brand recognition to
expand beyond its existing consumer market to include small and medium sized
businesses.  The first services offered in this area will be targeted to small-
office/home-office ("SOHO") customers and will include dial-up Internet access,
Web hosting, communications provisioning and related services.  See "Business --
Business Services".  The Company also plans to market Internet services to
Spanish-speaking and Hispanic customers in the United States in conjunction with
Telmex.  Telmex, which recently made a significant equity investment in the
Company, is the leading provider of local and long-distance telephone services
in Mexico and the largest ISP in Mexico.  See "Principal Stockholders".  The
Company is also seeking a partner with whom to offer a Spanish language portal
to the Internet, which the Company believes will be attractive to Spanish-
speaking and Hispanic Internet users.  See "-- Products and Services -- Spanish-
Speaking and Hispanic Market".

   EVALUATE ACQUISITION OPPORTUNITIES.  The Company evaluates acquisition
opportunities on an ongoing basis and, from time to time, is engaged in
discussions with respect to possible acquisitions or other business
combinations.  The Company may seek strategic acquisitions that can complement
the Company's current or planned business activities, particularly the expansion
of value-added services such as Web hosting.  The Internet services industry is
expected to undergo substantial consolidation over the next few years, and the
Company may also seek to acquire other ISPs as an additional means of customer
acquisition or entry into new markets.

PRODUCTS AND SERVICES

 PRODIGY INTERNET

   Prodigy Internet is an open standards-based Internet access service.  The
Prodigy Internet service combines the depth and breadth of the Internet with the
ease of use and organization of a traditional online service.  Prodigy Internet
users receive fast and reliable access to the Internet, Prodigy-branded content
powered by Excite and other Prodigy member services.  See "-- Principal
Outsourcing Arrangements -- Excite".

   As of June 30, 1998, there were 386,000 billable subscribers to the Prodigy
Internet service.  The Company includes as Prodigy Internet subscribers all
subscribers who are enrolled in a Prodigy Internet/Prodigy Classic combination
plan (111,000 at June 30, 1998).  See "Risk Factors -- Migration from Prodigy
Classic Service".

   The Prodigy Internet service provides subscribers with direct, high-speed
Internet access, an electronic mailbox enabling subscribers to send and receive
an unlimited number of text, graphics and multimedia messages, and disk space on
Prodigy's servers to host a personal Web page.  Prodigy Internet also offers:
(i) Prodigy-branded Web content, as selected, organized and edited by Excite
into a series of 13 "channels" covering topics such as Autos, Business &
Investing, Travel and Shopping; (ii) a personalized home page for each
subscriber which includes personalized news services, stock portfolios, weather,
local TV listings and sports scores; (iii) customer service and online member
support, including help files, tutorials and other online educational tools;
(iv) content generated by community members using communication tools such as
chat, message newsgroups and Web pages; and (v) access to online transactions on
the Web.

   The Prodigy Internet service is compatible with Internet standards and
protocols.  Standardization of both Prodigy Internet's content and network
permits use of industry-standard client/server software. Unlike some online
services that use proprietary protocols, Prodigy Internet merges seamlessly with
Web content and can be regularly updated to incorporate advances in Internet
technologies, such as new browsers, RealAudio and security devices for
electronic commerce.  Prodigy Internet is compatible with Microsoft Internet
Explorer and Netscape Navigator on the Windows 98, Windows 95 and Windows 3.1
operating systems and on Macintosh computers.  Microsoft Internet Explorer is
the primary browser shipped on disks that contain the Prodigy Internet software.

   The price plans for the Prodigy Internet service vary among acquisition
channels and target market segments and are subject to change.  Prodigy
Internet's principal price plans currently are (i) $19.95 per month for
unlimited usage with a 30-day money back guarantee, (ii) a discounted prepaid
annual plan of $189 for one year of unlimited usage (equivalent to $15.75 per
month), (iii) $9.95 per month for three months of unlimited usage, then $19.95
per month thereafter, and (iv) a free trial (for 30 to 60 days) with unlimited
usage and $19.95 per month thereafter.  In many distribution channels, Prodigy
is replacing free trial programs with money-back guarantees in order to attract
enrollees who are less likely to terminate service.

 PRODIGY CLASSIC

   The Prodigy Classic service, launched in 1988 as the world's first consumer-
focused online service, is based on a proprietary architecture and technologies.
Prodigy Classic offers most basic Internet capabilities, including e-mail
exchange, newsgroup support and Web browsing, as well as proprietary content
developed by or with third-party content providers such as Dow Jones and
Associated Press. Prodigy Classic's implementations of these Internet functions
predate current Internet standards and are not readily upgradable.  Prodigy
Classic is no longer marketed actively, although new enrollments 

                                       44
<PAGE>
 
continue to occur as a result of residual marketing efforts. The Company
encourages migration with targeted pricing offers, special hardware upgrade
promotions and the introduction of features and functions that have contributed
to the retention of Prodigy Classic subscribers. The Company anticipates that
revenues from Prodigy Classic will continue to decline over the next 12 to 15
months as the Company continues to focus on Internet-based products and
services. See "--Customer Acquisition and Marketing -- Migration from Prodigy
Classic". As of June 30, 1998, there were 252,000 billable subscribers to the
Prodigy Classic service.

   Prodigy Classic's principal price plans currently are $19.95 per month for
unlimited usage or $9.95 per month for five hours of usage with additional time
billed at $2.95 per hour. In order to encourage existing Prodigy Classic
subscribers to trial and convert to the Prodigy Internet service, Prodigy also
offers a plan that provides unlimited usage of both Prodigy Classic and Prodigy
Internet for a monthly fee of $19.95 or under a discounted prepaid annual plan
of $189 for one year of unlimited usage.

 CONSUMER VALUE-ADDED SERVICES

   The Prodigy Shopping Mall currently provides links to over 270 Web-based
stores and retailers, including Amazon.com, JCPenney, PC Flowers and Gifts,
Godiva Chocolate, CD Now, FAO Schwartz and Omaha Steaks.  In September 1998, the
Company launched co-branded paging services in partnership with SkyTel.  Over
the next six to nine months, the Company plans to roll out additional consumer
value-added services, such as the co-branded marketing of long-distance and
cellular telephone services, Internet-based faxing, online billing services, the
online procurement of additional goods and services and premium services such as
multiple mailboxes.  To enable targeted sales and marketing of value-added
services to existing subscribers, the Company is enhancing its data mining
capabilities.  There can be no assurance Prodigy will be successful in offering
additional consumer value-added services.  See "Risk Factors -- Risks of New
Services and Markets; Failure to Implement Business Strategy".

 BUSINESS SERVICES

   Prodigy has formed a business services division to develop and market
Internet-based services to commercial and business entities starting in late
1998.  These services are planned to include Internet access, basic and enhanced
hosting services and broadband services.  The Company also plans to extend its
Web hosting activities to include hosting of intranets and extranets for
businesses and electronic commerce sites.  Prodigy initially plans to target its
business services to the SOHO market in specific regions of the United States.
Prodigy does not currently provide any business services, other than Web hosting
to a limited number of customers, and there can be no assurance it will be able
to do so successfully.  See "Risk Factors -- Risks of New Services and Markets;
Failure to Implement Business Strategy".

   Prodigy was a pioneer in electronic commerce through its establishment of
standards and creation of applications that facilitated online shopping and
transacting, such as online banking and securities trading.  Prodigy currently
has the capability to provide the fundamental elements of electronic commerce --
Web hosting, hosting of intranets/extranets and high-speed dial access.
Prodigy's strategy is to provide turnkey solutions for electronic commerce.
Applications that Prodigy plans to roll out during 1999 include electronic
"shopping carts", order processing and tracking, online bill presentation and
payment processing, co-location hosting and, in conjunction with partners,
consulting and integration services for complex and large electronic commerce
sites.

   Prodigy's broadband strategy is designed to provide business customers with a
suite of Internet access and value-added services in conjunction with selected
technology and marketing partners.  The Company plans to introduce fractional
T1, T1, DS-3 frame relay and ATM (Asynchronous Transfer Mode) services beginning
in the fourth quarter of 1998 and xDSL (Digital Subscriber Line) services
commencing

in the first quarter of 1999. Commencing in 1999, Prodigy also plans to market
VPN (Virtual Private Networks) capability, Internet-based voice and fax services
and real-time EDI (Electronic Data Interface). Splitrock does not currently
support the broadband applications the Company plans to offer. The Company is in
discussions with potential broadband partners, including Splitrock, to support
various broadband applications. There can be no assurance the Company will reach
agreement with Splitrock or any other party, or that Prodigy will be successful
in introducing broadband services. See "-- Network and Related Infrastructure".

 SPANISH-SPEAKING AND HISPANIC MARKET

   Prodigy plans to market Internet services to Spanish-speaking and Hispanic
customers in the United States utilizing Telmex's marketing experience.
According to United States census data, there are approximately 17 million
persons in the United States age 5 or older who speak Spanish at home, and a
total of approximately 28 million U.S. residents are identified as Hispanic.
Prodigy believes this market is not currently being targeted by any other
nationwide ISP.  In addition, the Company is seeking a partner with whom to
offer a Spanish language portal to the Internet.  Although the Company has not
yet identified or reached agreement with a partner, the Company believes that a
Spanish language portal, once offered, will be attractive to Spanish-speaking
and Hispanic Internet users.

   Prodigy and Telmex are also in discussions for the introduction of Prodigy
Internet in Mexico. However, Prodigy and Telmex have not entered into an
agreement on this topic, and a number of issues must be resolved before Prodigy
Internet can be offered in Mexico, including marketing matters, the possible
migration of Telmex's existing Internet subscribers to Prodigy Internet,
technical issues relating to the interconnection of Telmex's network with the
network used for Prodigy Internet in the United States, and financial
arrangements.  There can be no assurance that Prodigy Internet will be offered
in Mexico.

   Telmex is the leading provider of local and long-distance telephone services
in Mexico and is the principal full-service telecommunications provider in
Mexico.  With approximately 85,000 subscribers, Telmex is also the largest ISP
in Mexico.  Telmex owns the nationwide network of local telephone lines and the
principal public long-distance telephone transmission facilities in Mexico, and
has built a nationwide data transmission network.  Based on total assets at
December 31, 1997, Telmex was the second-largest company in Mexico and the
largest company listed on the Mexican Stock Exchange. Telmex was the state-owned
monopoly telephone company in Mexico until 1990, when it was privatized and sold
to an investor group led by Grupo Carso, Southwestern Bell Corporation
(currently known as SBC Communications Inc.) and France Telecom, the French
state-owned telecommunications agency. Telmex is currently controlled by Carso
Global Telecom, the Company's principal stockholder.  Upon completion of the
Offering, Telmex will own    % of the Company's outstanding Common Stock.
See "Principal Stockholders".

CUSTOMER ACQUISITION AND MARKETING

   Prodigy utilizes a variety of customer acquisition channels and focuses on
the lowest-cost and most efficient channels, such as PC bundling.  The Company
believes that the strong brand recognition of the Prodigy name among consumers
and the nationwide reach of the network utilized by the Company provide the
Company with access to customer acquisition channels not available to local and
regional ISPs.

   The Prodigy Internet service is marketed through a variety of media vehicles,
including television and radio advertising.  See "Use of Proceeds".  Prodigy
Internet's target audiences are:  (i) purchasers of new desktop consumer PCs,
(ii) existing subscribers to online services who may be interested in moving to
an ISP and (iii) existing ISP subscribers who are dissatisfied with their
current service or attracted to 

                                       46
<PAGE>
 
the performance and features of Prodigy Internet. The Company believes that the
first target segment listed gives Prodigy effective access to both first-time
Internet users, who may be attracted by Prodigy Internet's ease-of-use, customer
service and online assistance, and existing Internet access subscribers who, in
conjunction with the purchase of a new PC, may be willing to switch to Prodigy
Internet. The Company believes that consumers in the second and third target
segments listed above are less likely to switch back from Prodigy Internet to
another ISP, are less price sensitive and are more receptive to value-added
services.

   Prodigy's marketing efforts position the Prodigy Internet service as a
productivity tool to help users obtain and communicate desired information
quickly and efficiently.  Marketing themes emphasize that the Prodigy Internet
service is superior in terms of connectivity (availability and reliability),
speed (up to 56 kbps), technology (digital switched ATM in most major markets)
and navigation and personalization (via the co-branded Prodigy/Excite content
services).  See "-- Products and Services" and "-- Network and Related
Infrastructure".

   PC BUNDLING.  The Prodigy Internet service is bundled with PCs under
arrangements where the Company pays a negotiated fee to the PC manufacturer only
if a subscriber enrolls from the PC distributed by the manufacturer.  PC
bundling is an attractive acquisition channel because the supplier bears the
distribution cost and it reaches many more potential subscribers than could be
reached through most other acquisition channels.  The Prodigy Internet software
is pre-loaded on the hard drives of selected PC models shipped by Packard
Bell/NEC, Hewlett-Packard, IBM, Gateway 2000, Toshiba, Sony, Acer, Fountain
Technology and Proteva.  On the Packard Bell/NEC PC units on which the software
is pre-loaded, Packard Bell/NEC promotes the Prodigy Internet service and
automatically selects Prodigy Internet as the customer's Internet service if no
other selection is made.  The Company is in the process of requiring new
enrollees through Packard Bell/NEC to supply credit card information for billing
rather than relying on subsequent paper billing.  The Company believes this
change may result in a lower level of new subscriber enrollments through the
Packard Bell/NEC channel but that the resultant enrollees will be less likely to
terminate service upon completion of the applicable trial period.  See "Risk
Factors -- Dependence on PC Bundling and Microsoft Relationship".

   MICROSOFT RELATIONSHIP.  Microsoft includes the Prodigy Internet service in
the online services folder of every copy of the Windows 98 and Windows 95 (OSR
2.5 release) operating systems shipped by Microsoft for sale in retail channels
or for loading on new PCs.  Prodigy Internet, Microsoft Network, America Online,
CompuServe and AT&T WorldNet are the only services in the online services
folders of Windows 98 and Windows 95 (OSR 2.5 release).  The Prodigy Internet
service is also included in Microsoft's ISP Internet Referral Service Program.
The Company believes that these arrangements enhance Prodigy's nationwide brand
presence.  See "Risk Factors -- Dependence on PC Bundling and Microsoft
Relationship".

   WEB-BASED.  Prodigy maintains a Web site (www.prodigy.com) that provides
Internet users with the opportunity to learn about and enroll in the Prodigy
Internet service.  Prodigy also has performance-based arrangements with several
leading Internet advertising companies, including Cyber Gold, DoubleClick
Direct, Net Creations and News America Digital Corporation.  In addition, as
part of its Excite arrangements, approximately nine million Prodigy banner ad
impressions appear each month throughout Excite's Web site to promote Prodigy
Internet to non-subscribers.  The Company believes these banner advertising and
other programs help target the "switcher" audience.

   RETAIL.  Prodigy has relationships with major retailers in the computer,
software and consumer electronics areas, including Circuit City, CompUSA,
Electronics Boutique, Babbages, Etc., Computer City, Micro Center and Office
Depot.  The Prodigy Internet software is currently available without charge at
more than 2,300 retail outlets nationwide.  These relationships typically
entitle Prodigy to establish displays containing software, along with incentive
applications such as free games and shareware, in 

                                       47
<PAGE>
 
prime locations next to cash registers. Prodigy supports these relationships
through the use of bounty programs, cooperative advertising and joint
promotional events. Prodigy also maintains a Prodigy Pro Program that provides
information, incentives and access to the Prodigy Internet service to over 4,000
retail sales people in partner stores. Prodigy is currently exploring expanded
distribution through additional retailers, including music stores, video rental
chains and book stores.

   DIRECT.  Prodigy pursues highly targeted and prequalified audiences in its
direct mailing and telemarketing efforts.  Prodigy's direct mail is targeted to
highly-qualified prospects, such as known Internet users and new PC purchasers.
Prodigy's inbound telemarketing program fulfills customer orders, 24 hours a
day, 7 days a week, 365 days a year, via a toll-free telephone number (1-800-
PRODIGY) which is widely promoted.  Prodigy's outbound telemarketing programs
focus on the reacquisition of recently disconnected members.  Prodigy's
telemarketing services, inbound and outbound, are outsourced. Prodigy maintains
an online, member-assisted referral program in which existing subscribers
receive account credits for signing up new members.

   MIGRATION FROM PRODIGY CLASSIC.  Prodigy acquires additional subscribers to
the Prodigy Internet service who migrate from Prodigy Classic.  Prodigy
encourages migration with targeted pricing offers, special hardware upgrade
promotions and the introduction of features and functions that have contributed
to the retention of Prodigy Classic subscribers, while emphasizing that the
Prodigy Internet service provides direct and reliable Internet access.  Because
a substantial portion of the remaining Prodigy Classic subscribers lack the
minimum hardware requirements for the Prodigy Internet service, in the fourth
quarter of 1997 Prodigy initiated special hardware discounts in conjunction with
PC and modem suppliers to encourage migration to the Prodigy Internet service.
As of June 30, 1998, 143,000 of the Prodigy Internet subscribers had migrated
from Prodigy Classic (most of whom are enrolled in a Prodigy Internet/Prodigy
Classic combination plan), and there were 257,000 remaining subscribers to
Prodigy Classic.  See "Risk Factors -- Migration from Prodigy Classic Service".

   RETENTION PROGRAMS.  Prodigy also develops programs to encourage conversion
from trial to paying status and improve customer retention.  Typical conversion
promotions are designed to induce usage because usage is a primary determinant
of conversion.  For example, in February 1998, Prodigy launched an e-mail
promotion that featured prizes such as Palm Pilots and software titles.  The
promotion was entered by approximately 10,000 trialers whose average usage
doubled during their trial period.  In June 1998, Prodigy introduced the
Personal Value Center, a member loyalty program designed to increase knowledge
and usage of the Web for transactions and other services.  Through the Personal
Value Center, Prodigy members can earn "points" based on usage and redeem such
points for gift certificates at selected retail stores.  Prodigy plans to extend
the Personal Value Center to travel services and other merchandise. The Company
also uses incentives to retain subscribers who might otherwise terminate
service.

CUSTOMER SERVICE

   Prodigy's customer service programs are designed to contribute to member
satisfaction and retention, while controlling costs, by combining selective
outsourcing with in-house services.  Prodigy believes that its customer service
programs, coupled with new release management which is both member-sensitive and
market responsive, have positioned Prodigy to provide customer support services
that are efficient and scalable for future growth.

   TELEPHONE SUPPORT.  Prodigy outsources its first contact, toll-free telephone
support to various vendors that provide support 365 days per year, 20 hours per
day (support is not available from 3:00 a.m. to 7:00 a.m., Eastern time).
Customers are assisted with Prodigy software installation, enrollment questions,
account management concerns, service access problems and disconnect requests.
By using multiple vendors, Prodigy is able to direct customer traffic flow
volumes on short notice, which Prodigy believes creates a competitive
environment and results in enhanced quality, performance and pricing. 

                                       48
<PAGE>
 
Geographic distribution of call centers allows for uninterrupted service to
Prodigy's member base in the event of regional disasters.

  IN-HOUSE CUSTOMER SUPPORT AND SYSTEMS.  Prodigy maintains an online member
services content area that provides a variety of support options to all members,
including real-time chat, instant messaging, newsgroups, message boards, e-mail,
and fax back.  Prodigy has integrated comprehensive help, tutorials, advisories,
frequently asked questions and tips online.  Prodigy also has an online "members
helping members" program, in which selected subscribers receive nominal monthly
compensation in exchange for providing personalized responses to members posting
inquiries on newsgroups and message boards. Prodigy's customer service
organization monitors customer service vendor performance with quantitative
metrics (including average wait time, first call resolution rate and abandon
rate) and qualitative controls (including call monitoring).  Prodigy also has
technically-trained customer service representatives to call subscribers with
unresolved problems.

  Prodigy maintains detailed customer records and documents each customer
request in a problem tracking system.  This system allows recurring problems to
be identified and communicated to the appropriate internal Prodigy function for
resolution.  Prodigy maintains a Web-based database that is accessible by all
vendor and employee customer service representatives on a real-time basis to
help ensure delivery of customer service in a consistent manner regardless of
where the contact is handled.

  BILLING.  Prodigy's customer billing system and services are outsourced to CSG
Systems, Inc. ("CSG"). CSG's billing system is highly customized and flexible
and supports prompt pricing changes.  CSG provides credit card and paper
billing, transaction processing and check handling.  A substantial majority of
Prodigy's current subscribers are billed through pre-authorized credit card
charges, while the remainder are issued invoices.  See "-- Principal Outsourcing
Arrangements -- CSG".

TECHNOLOGY

  Prodigy has been a technology pioneer in the online industry since its
formation in 1984 and introduced many concepts that would later be adopted for
the Web.  Continuing this pioneering heritage in the Internet industry, the
Prodigy Internet service utilizes a standards-based, proprietary service
provider platform and mail server developed by the Company.

  SERVICE PROVIDER PLATFORM.  The service provider platform is a suite of
functions which creates the infrastructure of a large-scale ISP.  Capabilities
include customer profile management, access control, authentication, billing and
customer care interfaces and other functions necessary to offer large-scale
Internet services.  The service provider platform is highly scalable (up to
millions of subscribers) and is compatible with industry standard products, such
as Netscape Web servers, Oracle databases, Net.Commerce (IBM's electronic
commerce solution) and Lotus Domino (an interface between Lotus Notes and the
Web).  The service provider platform also interfaces effectively with Prodigy's
mail server, and is built to open standards to enable the utilization of
applications from other suppliers.

  MAIL SERVER.  The Prodigy Internet service uses a scalable, reliable Internet
mail server.  The mail server draws on the fault-tolerance and scalability
provided by the underlying Oracle database to offer flexibility, ease of
operation and scalability.  Prodigy's mail server supports standard Internet
protocols, such as SMTP (Simple Mail Transfer Protocol), POP3 (Post Office
Protocol) and MIME (Multi-Purpose Internet Mail Extensions).  The mail system
also provides:

      Tools for Administrators.  Welcome messages, bulk mailers, quota controls
  (by realm, domain, household, small business or individual account), tools to
  manage spam and operational scripts and tools.

                                       49
<PAGE>
 
      Tools for Users.  User configured filters for prioritization and spam
  removal, and tools to enable the head of household or small business to
  administer a group of accounts.  Messages can contain any number of MIME
  attachments (up to a size limitation of 10 megabytes per mailbox) and are
  delivered without any promotional tag lines.

      Features for Business Customers.  Support for multiple domains and realms
  which enable Prodigy Internet to operate multiple Internet services under
  different brands on the same system base, and which enable an off-site
  administrator to control enterprise mailboxes.

      Configuration and Provisioning Interfaces.  The system supports a standard
  administrative interface that provides configuration and control of the mail
  system from external systems or via an HTML (Hypertext Markup Language)
  screen.  Standard APIs (Application Programming Interfaces) interface the
  system to external databases for user authentication and mailbox provisioning.

      Scaling Ability.  The system is designed to scale to millions of mailboxes
  with an architecture that supports hardware and data redundancy.

NETWORK AND RELATED INFRASTRUCTURE

  Subscribers access Prodigy's services by connecting to a network with their
PCs using local, toll-free or long distance telephone service.  The network
connects subscribers' PCs to the Internet as well as to Prodigy's hosting
servers, which store some of the data accessed during subscriber sessions.
Network connections are made through communications hardware, such as telephone
lines, routers, switches and modems, which serve to direct data and enable
communication among a variety of computer operating systems.  The network used
for the Prodigy Internet service is built to Internet standards, including
TCP/IP (Transmission Control Protocol/Internet Protocol) transmission and PPP
(Point-to-Point Protocol) access.  The Prodigy Classic service operates on
certain proprietary standards which are used only for Prodigy Classic.  The
Company outsources its network functions to Splitrock.  See "-- Principal
Outsourcing Arrangements -- Splitrock".

 NETWORK ARCHITECTURE

  The network infrastructure utilized by Prodigy Internet consists of three
primary tiers:  local points of presence ("POPs"); a middle tier, which connects
the POPs to regional hubs; and a backbone tier, which connects the regional hubs
to the Internet or Prodigy's data hosting center.  The network currently
includes approximately 650 POPs nationwide and has the capability to provide
dial-up access, with a local telephone call, to approximately 83% of the
households in the United States.  Prodigy also offers access to the Splitrock
network via an 800 telephone number for $.10 per minute without an additional
enrollment charge.

  Over 550 POPs currently provide 56 kbps access to Prodigy Internet subscribers
having modems of that speed.  Approximately 25% of all Prodigy Internet usage is
currently at 56 kbps.  The backbone implemented by Splitrock utilizes the
WorldCom network.  Twenty-one fully-meshed core nodes in major cities are
connected via high-speed links using digital ATM technology in all major
metropolitan markets. To optimize data transmission and facilitate the addition
of POPs as necessary, Splitrock employs an "ATM-to-the-edge" architecture,
placing ATM switches in all physical sites rather than only at major
transmission nodes on the backbone.  Eight connections from the backbone to the
Internet provide data transmission to and from servers on the Internet, and
Splitrock is building additional connections to other major networks with which
it has peering arrangements.

                                       50
<PAGE>
 
DATA HOSTING CENTER

  Prodigy's data hosting center, located in Yorktown Heights, New York, houses
approximately 400 high-capacity servers to store content and other data.  The
data center contains a mainframe complex which supports business support systems
such as subscriber session accounting and reporting, customer service support
systems and business accounting.  Prodigy's data center hosts a variety of
applications that are scalable to millions of users.  The use of standard
interfaces allows integration of products offered by a broad spectrum of
vendors, including IBM, Microsoft and Netscape.  Supported operating system
platforms include UNIX/AIX, NT, MVS and TPF, and installed database products
include Oracle and DB2.

  Prodigy's data hosting center is equipped with triple redundant power systems
and is housed in a climate and humidity controlled environment.  Both battery
and diesel power backup systems are installed to preclude outages that might
otherwise result from interruption of utility power to the building.  All
production host systems have backup processors and peripherals, and all critical
data is backed up to tape daily.  Facilities and data are physically secured by
incrementally restrictive card key locks, and logical data security is provided
by built-in operating system security features.  Firewall technology is
implemented to protect critical systems, and servers that are open directly to
the Internet are installed on a network separate from those that are not.  In
addition, anti-hacking measures are in place.

RELIABILITY AND AVAILABILITY

  Reliability and availability are key objectives of Prodigy's network and
hosting configurations. Splitrock has designed and is rolling out its network to
meet specified service level objectives, including the P.01 grade of service (no
more than one busy signal in 100 dial-up attempts during the busiest hour of the
day on the busiest day of the week), and specified objectives for site and
overall system availability and backbone transit delay.  Splitrock accumulates
and analyzes statistics on each access line, and lines exhibiting quality
problems are removed from service and referred for repair.  In addition, Prodigy
has integrated Inverse's Access Ramp product into the Prodigy Internet software
to gather data on the actual connection experiences of subscribers who have
agreed to have their connection experiences measured. Prodigy reports problem
sites to Splitrock for action.

  At Prodigy's data hosting center, Prodigy operates a 24x7 operations control
center and Splitrock operates a 24x7 network operations center.  Circular
hunting is employed on local access telephone lines to ensure that a problem
with a single line does not disable the entire access site.  Where feasible, the
access lines are distributed among multiple modem subsystems and access servers
to provide diversity. The hosting center is connected to the backbone via
redundant DS3 lines.  Splitrock's fully-meshed core node architecture provides
multiple transmission routes across the backbone for optimal speed and
reliability.

  Inverse measures and reports eight parameters of ISP network performance (24-
hour call failure rate, evening-hour call failure rate, business-hour call
failure rate, initial modem connect speed, average time to login, average DNS
(Domain Name System) lookup time, average Web throughput and average total Web
failures/timeouts).  Since completion of Splitrock's network in May 1998,
Inverse has given Prodigy Internet ratings of A+ or A for 24-hour call failure
rate for each of the months of May, June, July and August 1998, which ratings in
each case exceeded or equalled the comparable overall industry rating given by
Inverse based on 13 major providers of Internet access services.  The Company
believes call failure rate is the most important network measure in terms of
customer satisfaction.  Overall, Prodigy Internet exceeded or equalled the
comparable industry rating given by Inverse in at least seven of the eight
parameters for each of the months of May, June, July and August 1998.  Investors
should not place undue reliance on Inverse's reports as a measure of network
performance because such reports do not measure and report on all factors that
may affect the quality of the Company's services.  For example, Inverse's
reports are based on tests conducted on selected days at a random sampling of
only 42 of Splitrock's 

                                      51
<PAGE>
 
POPs, and Inverse's reports cited above cover only a four month period. There
can be no assurance Splitrock's network will be able to sustain the level of
performance indicated by Inverse's reports. See "Risk Factors -- Network Risks".

PRINCIPAL OUTSOURCING ARRANGEMENTS

  The Company follows a "best of breed" outsourcing philosophy in which it
selects from among competing suppliers in order to control costs, enhance
service quality and enable the Company to focus on its core strengths.

SPLITROCK

  Prodigy owned and operated its own network in the United States until July 1,
1997.  Effective July 1, 1997, Prodigy conveyed its network assets to Splitrock
in exchange for Splitrock's agreement to build and operate the Splitrock network
described above, hire all Prodigy employees engaged in Prodigy's network
operations and assume certain POPs leases and other liabilities.  The Company
believes its Splitrock network arrangements present a number of significant
advantages to Prodigy.  In addition to shifting to Splitrock the capital costs
of network expansion and enhancement as well as network operating and personnel
expenses, the Company believes these arrangements have reduced Prodigy's network
costs and made such costs more predictable.  Prodigy also believes the variety
and sophistication of data services available to it will increase due to
anticipated network enhancements and upgrades.  See "Risk Factors -- Network
Risks".  The Splitrock network arrangements cover only the United States, and
Prodigy would need to make other network arrangements in order to offer services
in foreign countries.

  Splitrock is required to provide dial-up network access in all locations in
which Prodigy provided dial-up service as of June 30, 1997.  Prodigy may require
additional sites to be added if certain coverage and usage parameters are met.
Splitrock may also provide access to the network to other customers. Splitrock
is requited to provide a backbone network based on ATM technology and is
required to support transmission via SLIP (Serial Line Internet Protocol), PPP
and TCP/IP.  Splitrock is also required to support the proprietary standard
utilized by Prodigy Classic through December 31, 1999.

  Splitrock is required to meet specified service level objectives, including
the P.01 grade of service and specified objectives for site and overall system
availability and backbone transit delay.  Splitrock's failure to meet the
specified service level objectives will result in financial penalties.  If
Splitrock fails to meet specified service level objectives for an extended
period of time, Prodigy may terminate the agreement. In addition, if there is a
system-wide failure, or Splitrock breaches specified financial covenants,
Prodigy will have the right to terminate the agreement or assume responsibility
for operating the network at Splitrock's expense.

  Splitrock charges Prodigy a monthly fee per subscriber for usage by Prodigy's
subscribers.  If the average hourly usage by Prodigy's subscribers in any month
exceeds a specified threshold, Prodigy must pay Splitrock an additional amount
per hour in excess of such threshold for such month.  The agreement includes
minimum monthly charges and is terminable by Prodigy upon payment of a specified
early termination charge.  During the year ended December 31, 1997 and the six
months ended June 30, 1998, the Company incurred network charges to Splitrock of
$22.7 million and $32.6 million, respectively.  See "Risk Factors -- Potential
Conflicts of Interest".

  The agreement has an initial term of four years through June 30, 2001 and is
subject to automatic renewal for successive one-year terms unless terminated by
either party upon 12 months' notice.  Until termination of the agreement,
Prodigy has agreed that Splitrock will be Prodigy's primary provider of network
services.  During this period, Prodigy must give Splitrock advance notice of,
and the opportunity 

                                      52
<PAGE>
 
to discuss with Prodigy, any forms of service access (other than network access)
that Prodigy wishes to pursue in the United States.

EXCITE

  In January 1998, Prodigy entered into an agreement with Excite, Inc.
("Excite") under which Excite, commencing in April 1998, provides subscribers to
the Prodigy Internet service with Prodigy-branded Excite content using Excite's
"My Channel" technology. This arrangement enables Prodigy to offer Excite's
extensive editorialized content and content personalization and communication
features under the Prodigy brand without incurring the time or expense to
develop similar capabilities internally.

  Prodigy's agreement with Excite (i) has an initial term of three years and
automatically renews for successive one-year terms unless Excite elects not to
renew it, (ii) is terminable by Prodigy upon 60 days' notice, (iii) makes Excite
Search the exclusive search engine, Excite NewsTracker the exclusive
personalized Internet news clipping service and Excite Shopping Search the
exclusive Internet shopping search tool on Web pages provided to subscribers to
the Prodigy Internet service, (iv) does not prohibit Prodigy from entering into
similar agreements with other content providers (except as provided in the
preceding clause (iii)) or prohibit Excite from entering into similar agreements
with other ISPs, (v) provides for a sharing of all revenue derived from the
advertising banners on the co-branded Prodigy/Excite Internet service, and (vi)
gives Prodigy free advertising banner impressions throughout Excite's Web site
to promote the Prodigy Internet service.

CSG

  Prodigy outsources its customer billing to CSG.  CSG is a leading provider of
customer care and billing solutions for various telecommunications providers,
including many of the largest cable television and direct broadcast satellite
providers.  CSG is Prodigy's exclusive provider of billing services for the
Prodigy Internet and Prodigy Classic services but not for premium services or
other billing services.  CSG charges Prodigy a monthly fee based on the number
of subscribers, subject to a specified minimum charge, as well as a monthly
minimum fee for ongoing development and support.  The agreement between Prodigy
and CSG expires June 30, 2001.

COMPETITION

  The industry in which the Company competes is intensely competitive and
includes a number of significant participants, including ISPs, proprietary
online service providers and major international telecommunications companies,
as well as Internet-search services and various other telecommunications
companies.  There are more than 4,000 ISPs in the United States, most of which
operate small, local businesses.  Additional regional telephone operating
companies, long-distance carriers and cable companies may also elect to compete
with Prodigy.  Various partnering arrangements have recently been established
between Internet-search service companies and major telecommunications
companies, which could result in increased competition for Prodigy.  Moreover,
the Company faces competition from companies that provide broadband connections
to households, including local and long-distance telephone companies, cable
television companies and electric utility companies.  Broadband technologies
offer significantly faster Internet access than conventional modems, and such
companies could include Internet access in their basic service packages, could
offer access for a nominal additional charge or could prevent the Company from
delivering Internet access through the cable or wire connections that such
companies own.  See "Risk Factors -- Intense Competition".

  Among the larger providers of ISP services are EarthLink Network, Inc. (which
has a strategic relationship with Sprint Corporation), MindSpring Enterprises,
Inc., Microsoft Network, AT&T WorldNet, MCI Internet, IBM Internet Connection,
PSINet Inc., GTE Internetworking (which includes the former ISP 

                                      53
<PAGE>
 
business of BBN Corporation), Netcom On-Line Communications Services, Inc.
(owned by ICG Communications, Inc.) and Concentric Network Corporation.
Microsoft's ownership of the dominant PC operating system and the Microsoft
Internet Explorer browser may give Microsoft Network certain competitive
advantages, including distribution and marketing synergies. Prodigy also
competes with America Online, which offers the America Online and CompuServe
proprietary online services over closed networks, as well as Internet access.

  Prodigy believes that the principal competitive factors in the ISP industry
are speed and reliability of access, ease of use, brand name recognition,
network coverage, customer service and price.  Prodigy believes that its
services compete effectively on the basis of all of these factors.

GOVERNMENT REGULATION

  Internet access and online services are not subject to direct regulation in
the United States, but changes in the regulatory environment relating to the
telecommunications and media industry could have an effect on Prodigy's
business.  For example, Federal Communications Commission regulatory review and
rulemaking could result in regulation of the Internet and online services
industry which could result in increased telecommunications costs for
participants in the Internet industry, including Prodigy.  The Company cannot
predict whether, or to what extent, any such new rulemaking will occur, or what
effect any such rulemaking would have on Prodigy.

  The Communications Decency Act of 1996 (the "Communications Decency Act"),
which was held unconstitutional by the United States Supreme Court in June 1997,
had generally made it illegal, subject to certain defenses, for persons to
knowingly use an interactive computer service to send or display "indecent"
communications to minors.  The Company cannot predict whether similar federal or
state legislation will be enacted in the future, whether any such future
legislation would be upheld, how courts would interpret any such future
legislation or what effect, if any, such legislation would have on the Company.
There also are laws that make it illegal to traffic in obscene or child
pornographic materials, including by a computer, and accordingly Prodigy's
servers do not host certain newsgroups which it believes traffic in child
pornography.  While the Company does not believe that its activities will
violate any of these laws, it cannot predict how a court would interpret these
laws in the Internet context or whether a court would hold that Prodigy Internet
has a duty to monitor material being transmitted or, if notified that illegal
material is being transmitted, to attempt to stop or restrict such
transmissions.  See "Risk Factors -- Government Regulation".

  In addition, the applicability to Prodigy of existing laws governing issues
such as intellectual property ownership, defamation and personal privacy is
uncertain.  Courts have indicated that, under certain circumstances, online
service providers and ISPs could be held responsible for the publication of
defamatory material or for failure to prevent the distribution of material that
infringes copyrights owned by others.  The Company does not edit or otherwise
monitor the content accessed by subscribers to Prodigy Internet, although the
Company does filter certain words on Prodigy Classic.  Future interpretations by
the courts of online defamation, privacy, copyright infringement and other legal
issues is also uncertain.

  In March 1997, Prodigy entered into a Consent Order with the Federal Trade
Commission (which became effective in March 1998) regarding use of the word
"free" and similar words in advertising, disclosure of the financial terms and
conditions of services, practices with respect to electronic funds transfers and
certain related matters.  The Consent Order has a duration of twenty years and
imposes various recordkeeping requirements.  The Company believes that it is in
compliance with the Consent Order and that its continuing compliance with the
Consent Order will not have a material adverse affect on Prodigy's business.
America Online is subject to a similar Consent Order which governs its marketing
of services under both the American Online and CompuServe brands.

  In September 1998, the Company received a letter from the Office of the
Attorney General of New York notifying the Company that the "advertising and
certain other practices" of Prodigy and other unnamed ISPs were being
investigated by the Attorneys General of New York and 19 other states.  The
letter stated that the inquiry was a follow-up to the settlement between America
Online and many states in May 1998 concerning the following issues:  disclosures
for free offers, representations concerning pricing, disclosures concerning
premium areas, disclosures for communications charges, advertising to minors,
cancellation procedures, unauthorized charges to credit cards or bank accounts
and changes to the service agreement.  The letter requested that the Company
voluntarily supply various documents and other information relating to the
marketing and provision of its services.  The Company plans to cooperate with
the inquiry and believes that its outcome will not have a material adverse
effect on the Company.

EMPLOYEES

  At June 30, 1998, the Company had 304 full-time employees, of whom 48 were in
sales and marketing, 85 were in technology and product development, 49 were in
customer service, 76 were in technical services and 46 were in management,

June 30, 1998.

FACILITIES

  Prodigy leases 97,000 square feet of office space in White Plains, New York.
The lease expires December 31, 2004 and Prodigy has a right of first offer upon
expiration.  The current annual base rent is $2,275,000 and Prodigy is required
to pay an allocated portion of taxes and operating expenses.  Prodigy has
established a letter of credit in the initial amount of $3,930,000 (declining
ratably over the lease term) to secure the rent payments.

  Prodigy also leases 80,000 square feet in Yorktown Heights.  The lease expires
February 28, 2001 with two five-year renewal options in Prodigy's favor.  The
current annual base rent is $687,000 and Prodigy is required to pay associated
taxes and operating expenses.  Prodigy uses approximately 57,500 square feet of
its Yorktown Heights facility for its data hosting center and subleases the
balance to Splitrock.  See "-- Network and Related Infrastructure -- Data
Hosting Center".

                                      55
<PAGE>
 
  The Company leases approximately 16,000 square feet of office space in
Medford, Massachusetts under a lease expiring on August 1, 2001. Prodigy vacated
this facility, which formerly housed the headquarters for Prodigy's
international operations, in June 1998 and is seeking to sublease it.

  For additional information regarding the Company's leased facilities and its
aggregate rental expenses, see Note 12 to the Company's Consolidated Financial
Statements.

  The Company believes that its existing facilities are adequate for its current
needs and that suitable additional space will be available as needed.

LEGAL PROCEEDINGS

  On November 27, 1996, Malcolm Haynes and Lightwave, Ltd., a Cayman Islands
corporation, filed a lawsuit in the District Court of Clark County, Nevada,
against the Company, IW, Comstar Cellular Network, Inc., Greg C. Carr, Terrance
P. Dillon, Duncan E. Wine and Blaize Kaduru.  Mr. Carr is the former Chairman of
the Board of the Company and a former principal stockholder of the Company, and
was a director and principal stockholder of IW.  Mr. Dillon was a director and
principal stockholder of the Company, was a director, officer and principal
stockholder of IW and was a director and technical advisor to Comstar.  Mr. Wine
is a former principal stockholder of the Company and IW.  Mr. Kaduru is a former
principal stockholder of the Company and IW, was an officer of IW and was a
director and officer of Comstar.  Mr. Haynes was co-founder, President and a
director of Comstar and claims that he and Mr. Wine each hold a 30% interest in
Lightwave.  In connection with IW's acquisition of the assets and liabilities of
Comstar in August 1994, IW issued to Comstar all then outstanding common stock
of IW, which Comstar then distributed as a liquidating dividend to the holders
of certificates for common stock of Comstar.  Each holder of a certificate for
common stock of Comstar was required to acknowledge and accept the terms of the
Comstar acquisition and release Comstar and IW from all claims which such holder
may have had against either Comstar or IW.  See "Corporate History and Certain
Transactions -- Prior Corporate History".  Pursuant to the foregoing, Comstar
offered 4,800,000 shares of IW's common stock to Mr. Haynes, but Mr. Haynes
refused to participate and therefore received no shares.  The lawsuit filed by
Mr. Haynes and Lightwave alleges, among other things, that Messrs. Dillon, Wine
and Kaduru breached their fiduciary duties to the plaintiffs, that Mr. Wine
defrauded or made misrepresentations to the plaintiffs, that Mr. Wine
misappropriated a corporate opportunity belonging to Lightwave, that all
defendants are liable for conversion of plaintiffs' shares of common stock, and
that IW and Mr. Carr aided and abetted the wrongful conduct of Messrs. Dillon,
Wine and Kaduru.  The lawsuit seeks to compel the defendants to provide to the
plaintiffs 18,000,000 shares of Common Stock of the Company or the fair market
value thereof, to impose a constructive trust on the shares of Common Stock
received by Messrs. Dillon, Wine and Kaduru in the Comstar acquisition, and
other monetary damages and declaratory and equitable relief.  On February 25,
1998, the Court granted the motion of the Company and Mr. Carr to dismiss the
lawsuit against them for lack of personal jurisdiction in Nevada, and the
lawsuit is continuing against the other defendants.  Unless this decision is
overturned on appeal, the plaintiffs cannot pursue this lawsuit against the
Company and Mr. Carr in Nevada, although the plaintiffs could pursue these
claims in a new lawsuit filed in any state or states where personal jurisdiction
over the Company and Mr. Carr could be established and where the applicable
statute of limitations has not expired.  If a new lawsuit is filed, the Company
intends to defend it vigorously, but there can be no assurance that its outcome
would not have a material adverse effect on the Company's business, financial
condition, results of operations or prospects or result in substantial dilution
to the Company's stockholders.

  On June 11, 1998, Lycos, Inc. ("Lycos") filed a complaint and motion for
preliminary injunction in the Superior Court of Middlesex County, Massachusetts
against the Company.  The lawsuit alleges, among other things, that the Company
breached a license agreement with Lycos by entering into its portal outsourcing
agreement with Excite in January 1998 and by terminating the license agreement
between Lycos and the Company.  See "-- Principal Outsourcing Arrangements --
Excite".  The lawsuit seeks 

                                      56
<PAGE>
 
specific performance of the license agreement between Lycos and the Company, a
preliminary and permanent injunction enjoining the Company from terminating the
license agreement between Lycos and the Company and from performing under its
agreement with Excite, money damages and attorneys' fees. A hearing on Lycos'
motion for preliminary injunction has been adjourned because the parties are in
negotiations to settle the lawsuit. However, there can be no assurance the
lawsuit will be settled. If the lawsuit is not settled, the Company intends to
defend it vigorously, but there can be no assurance that its outcome will not
have a material adverse effect on the Company's business, financial condition,
results of operations or prospects.

     Dougherty, L'Heureux and Gopal and Ms. Pooth from $2.00, $2.00, $3.00,
     $3.00 and $3.00 per share, respectively, to $1.00 per share.  See "-- Stock
     Plans --1996 Stock Option Plan".

(2)  Amounts reported in these columns represent amounts that may be realized
     upon exercise of the options immediately prior to the expiration of their
     term assuming the specified compound rates of appreciation (5% and 10%) on
     the market value of the Common Stock on the date of option grant over the
     term of the options. These numbers are calculated based on rules
     promulgated by the Securities and Exchange Commission and do not reflect
     the Company's estimate of future stock price growth.  Actual gains, if any,
     on stock option exercises and Common Stock holdings are dependent on the
     timing of such exercise and the future

     of appreciation assumed in this table can be achieved or that the amounts
     reflected will be received by the individuals.

     these options were cancelled. The remainder of these options will be

STOCK PLANS

 1996 STOCK OPTION PLAN

   The Company's 1996 Stock Option Plan (the "Option Plan") permits the issuance
of up to 12,500,000 shares of Common Stock upon the exercise of options granted
under the Option Plan.  The Option Plan is currently administered by the
Compensation Committee of the Board of Directors.  Under the Option Plan, the
Board or Compensation Committee may grant incentive stock options within the
meaning of Section 422 of the Internal Revenue Code of 1986 ("incentive stock
options") and stock options not intended to qualify as incentive stock options
("non-statutory stock options").  Stock options may be granted under the Option
Plan to employees, directors, consultants and advisors of the Company.  Only
employees of the Company and its subsidiaries are eligible to receive incentive
stock options.  The Option Plan expires in June 2006.

   Subject to the provisions of the Option Plan, the Board and Compensation
Committee have the authority to determine:  (i) to whom options will be granted;
(ii) the time when options may be granted; (iii) the number of shares to be
covered by each option; (iv) when the option becomes exercisable; and (v) the
exercise price of the option (which price, in the case of incentive stock
options, may not be less than the fair market value of the Common Stock on the
date of grant, or in the case of incentive stock options granted to employees
who own, directly or indirectly, more than 10% of the total combined voting
power of all classes of stock of the Company, 110% of the fair market value of
the Common Stock on the date of grant).  The Company's Chief Executive Officer
has authority, without prior Board or Compensation Committee approval, to grant
options under the Option Plan and to determine the terms of such options,
provided that  no grants may be made to executive officers and options may not
exceed 100,000 shares per employee per year.

   The Company's philosophy is to utilize equity incentives to motivate and
retain management and employees.  In June 1997, the exercise price of all
outstanding options held by active employees with exercise prices in excess of
$3.00 per share was reduced to $3.00 per share, representing the then-current
fair market value as determined by the Board of Directors.  In this repricing,
options to purchase an aggregate of 1,533,549 shares with exercise prices
ranging from $5.00 to $7.00 per share were repriced to $3.00 per share,
including an option to purchase 29,000 shares held by Ms. Pooth.  In May 1998,
the exercise price of all outstanding options held by active employees with
exercise prices in excess of $1.00 

                                      68
<PAGE>
 
per share was reduced to $1.00 per share, representing the then current fair
market value as determined by the Board of Directors. In this repricing, options
to purchase an aggregate of 5,828,515 shares with exercise prices ranging from
$2.00 to $3.00 per share were repriced to $1.00 per share, including options to
purchase 625,000, 375,000, 200,000, 70,000 and 71,000 shares held by Messrs.
Salameh, Dougherty, L'Heureux and Gopal and Ms. Pooth, respectively. The purpose
of these repricings was to restore the performance incentives intended to be
provided by options.

   As of August 31, 1998, (i) there were outstanding options under the Option
Plan to purchase an aggregate of 9,472,312 shares of Common Stock at a weighted-
average exercise price of $1.56 per share, (ii) an aggregate of 6,089 shares of
Common Stock had been issued upon exercises and (iii) 3,021,599 additional
shares of Common Stock were reserved for future option grants.  As of August 31,
1998, Messrs. Salameh, Dougherty, L'Heureux and Pooth held options to purchase
625,000, 375,000, 375,000 and 375,000 shares, respectively, at an exercise price
of $1.00 per share, and Mr. Henkel held an option to purchase 750,000 shares at
$2.00 per share.  The Board of Directors intends, at its next Board meeting, to
grant Ms. Hirsch an option to purchase 375,000 shares at $2.00 per share in
accordance with the terms of her Employment Agreement.

1998 EMPLOYEE STOCK PURCHASE PLAN

   In September 1998, the Company adopted the 1998 Employee Stock Purchase Plan
(the "Purchase Plan") which becomes effective upon the closing of the Offering.
The Purchase Plan authorizes the issuance of up to 2,000,000 shares of Common
Stock ("Shares") to eligible employees of the Company and its subsidiaries.
Employees are eligible to join the Purchase Plan if their customary employment
is more than 20 hours per week and for more than five months in any calendar
year.  Employees who own (directly or indirectly, taking into account the Shares
subject to purchase under the Purchase Plan) 5% or more of the total combined
voting power or value of all classes of stock of the Company are not eligible to
participate.

   The Purchase Plan permits shares to be purchased at the end of "Purchase
Periods" occurring during each "Offering Periods".   Unless otherwise provided
by the Board prior to commencement, an Offering Period will begin on each May 16
and November 16, and continue for a period of 24 months.  A Purchase Period will
begin on each May 16 and November 16, and will continue for a period of six
months, ending on the following November 15 or May 15, respectively.  The first
Offering Period and the first Purchase period will commence upon the closing of
the Offering.  The last day of each Purchase Period (i.e., May 15 or November
15) is the date on which Shares are actually purchased (a "Purchase Date").

   Each eligible employee may enroll in an Offering Period by filing an election
by the first payroll date occurring during the Offering Period (or up to 45 days
after the start of the Offering Period if approved in advance by the Board),
provided such eligible employee is not already participating in an Offering
Period which began earlier.  When enrolling in an Offering Period, the employee
must specify the amount to be withheld from pay on each payroll date occurring
during the Offering Period, which cannot exceed 10% of the employee's basic rate
of pay (determined at the beginning of the Offering Period).

   The amount withheld from a participating employee's pay is credited to his or
her account under the Purchase Plan.  Unless the electing employee withdraws
from participation (in which case the employee will be refunded the amount in
his account, without interest), the funds in his or her account will be used on
each Purchase Date to purchase that number of Shares which can be purchased at a
price equal to the lower of 85% of the fair market value of the Shares on the
first day of the Offering Period and 85% of the fair market value of the Shares
on the Purchase Date. "Fair market value" is defined as the last sale price of
the Common Stock on the Nasdaq National Market on the applicable day.

                                      69
<PAGE>
 
   The number of Shares otherwise subject to purchase by an employee on a
Purchase Date will be reduced proportionately (as described in the Purchase
Plan) if the number of Shares available under the Purchase Plan, or available
with respect to the Offering Period, is not sufficient to satisfy the purchase
rights of all employees on such Purchase Date.  In addition, the number of
Shares otherwise subject to purchase on a Purchase Date will be reduced to the
extent necessary to insure that the employee's right to acquire Shares under the
Purchase Plan does not accrue at a rate which exceeds $25,000 in fair market
value (as determined on the first day of the Offering Period of reference) for
each calendar year during which the employee was an active participant in the
Purchase Plan.

   If an employee terminates employment for any reason (including death or
disability), or withdraws from an Offering Period, such employee will not be
entitled to acquire Shares on any succeeding Purchase Date occurring with
respect to such Offering Period, and the amount in his or her account will be
refunded without interest.   An employee withdrawing from an Offering Period
will not be entitled to rejoin the Purchase Plan with respect to such Offering
Period but may, if such employee otherwise qualifies, rejoin the Purchase Plan
with respect to any subsequent Offering Period.

   The Purchase Plan will be administered by the Compensation Committee of the
Board.  The amounts paid to the Company with respect to the purchase of Shares
may be used for any corporate purpose.  The employees participating in the
Purchase Plan will have no interest, voting rights or other privileges with
respect to the Shares until they receive a certificate representing such Shares.

   Because participation in the Purchase Plan is voluntary, the Company cannot
now determine the number of Shares to be purchased by any particular current
executive officer, by all Named Executive Officers as a group or by non-
executive employees as a group.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

   The current members of the Compensation Committee of the Board of Directors
are Messrs. Elias and Nakfoor.  No executive officer of the Company has served
as a director or member of the compensation committee (or other committee
serving an equivalent function) of any other entity, whose executive officers
served as a director of or member of the Compensation Committee of the Board of
Directors.

                   CORPORATE HISTORY AND CERTAIN TRANSACTIONS

ACQUISITION OF PRODIGY SERVICES COMPANY

 ACQUISITION TERMS

   On June 17, 1996, the Company acquired PSC from its owners, IBM and Sears,
for $46,950,000 in cash (including $6,150,000 paid to financial advisors) plus
the issuance of 8% Contingent Convertible Promissory Notes (the "Contingent
Notes") valued at $30,500,000 by an independent appraiser.  The Contingent Notes
entitled IBM and Sears to receive in the aggregate (i) in the event of a
qualifying initial public offering, 15% of the Company's Common Stock on a
fully-diluted basis, or (ii) in the event the Company is acquired, 15% of the
consideration received, provided that the value of the consideration payable to
IBM and Sears in either case was limited to $200,000,000 plus accrued interest.
IBM and Sears assumed PSC's four existing retirement plans and all obligations
thereunder.  Effective as of the closing, IBM received sole ownership of six
patents jointly-owned with PSC, the Company received sole ownership of two other
jointly-owned patents, and IBM and the Company entered into the patent cross-
license agreements described under "Business -- Proprietary Rights".  The
Company is obligated to indemnify IBM and Sears for claims and liabilities
arising out of PSC's business, whether arising before or after the closing of
the Prodigy Acquisition, except with respect to the retirement plans assumed by
IBM and Sears.

   In November 1997, IBM and Sears (i) agreed that the consideration receivable
upon conversion of the Contingent Notes would be based on the valuation of the
Company in excess of $250,000,000 (with the aggregate consideration payable to
IBM and Sears still limited to $200,000,000 plus interest from June 17, 1996)
and (ii) were granted Contingent Stock Purchase Warrants (the "Contingent
Warrants") to purchase up to 15% of the Common Stock of the Company at 130% of
the fair market value thereof at the time of conversion of the Contingent Notes.
As a condition to these arrangements, Carso Global Telecom prepaid (on behalf of
and as an advance to the Company) the balance due on the Company's former White
Plains lease ($5,831,000) and established a $4,000,000 letter of credit,
declining quarterly over three years, to secure certain payment obligations of
the Company under PSC contracts for which IBM and Sears remain liable.  See
Notes 1, 4 and 9 to the Company's Consolidated Financial Statements.

 REORGANIZATION

   In connection with the Prodigy Acquisition, the Company was formed to acquire
PSC and to hold all of the outstanding stock of IW, and IW retained its existing
cellular telephone assets and conveyed its other assets to other subsidiaries of
the Company.  The new holding-company structure was created to effect the
Prodigy Acquisition and to consolidate the Company's cellular telephone assets
within IW in order to position IW for separate sale or financing.  As a result
of this reorganization, all outstanding Common Stock of IW was automatically
converted into Common Stock of the Company on a one-for-one basis.  See "--
Prior Corporate History".

 TREATMENT OF CONVERTIBLE NOTES AND CONTINGENT WARRANTS IN THE OFFERING

   Upon the closing of the Offering (at an assumed initial public offering price
of $     per share), IBM and Sears will each (i) receive        shares of Common
Stock pursuant to the conversion of its Contingent Note and (ii) hold a
Contingent Warrant to purchase        shares of Common Stock at an exercise
price of $       per share (subject to customary anti-dilution adjustments) at
any time prior to the third anniversary of the Offering.  IBM and Sears have
customary piggyback and demand registration rights, at the Company's expense,
with respect to the Common Stock issuable upon conversion of the Contingent
Notes or exercise of the Contingent Warrants, including customary
indemnification and other provisions. After conversion of the Contingent Notes
or exercise of the Contingent Warrants, IBM and Sears have 

                                      71
<PAGE>
 
agreed to vote their shares of Common Stock in accordance with the voting
recommendations of the Company's Board of Directors.

OTHER ARRANGEMENTS WITH IBM AND SEARS

   In September 1998, the Company agreed in principle to sell to IBM a version
of Prodigy's service provider platform software enabling an ISP to manage
subscriber data.  IBM will pay the Company $2,000,000, and the Company will
retain a perpetual, royalty-free license to use and upgrade the software for its
own use.  The Company does not use such software to manage its own subscriber
data.  See "Business -- Technology".

   Between the closing of the Prodigy Acquisition and October 1997, IBM and
Sears paid the State of New York $3.4 million for sales and use taxes assessed
against PSC for certain periods ended prior to the Prodigy Acquisition.  In
October 1997, the Company, IBM and Sears agreed that each of them would be
liable for one-third of all sales and use taxes assessed against PSC for periods
ended prior to the Prodigy Acquisition, and Carso Global Telecom paid (as an
advance to the Company) $567,000 to each of IBM and Sears in light of prior
payments of such taxes by IBM and Sears.

   Prior to outsourcing its network to Splitrock, Prodigy utilized a network
backbone and certain POPs provided by Advantis (a joint venture of IBM and
Sears) and subsequently by IBM Global Services after IBM acquired Sears'
interest in Advantis during 1997.  Splitrock continues to use certain POPs
provided by IBM Global Services.  The Company also purchases computer equipment
from IBM on normal commercial terms.  During the period June 17, 1996 through
December 31, 1996, the year ended December 31, 1997 and the six months ended
June 30, 1998, respectively, the Company paid IBM/Advantis an aggregate of
$17,116,000, $37,995,000 and $22,867,000 for network services and equipment
purchases.

   At the time of outsourcing its network to Splitrock, Prodigy had certain non-
cancellable commitments to purchase network services from Advantis/IBM Global
Services.  In September 1998, in settlement of such commitments, the Company
agreed in principle to purchase from IBM, on normal commercial terms, certain
maintenance and voice-related network services in the aggregate amount of
$7,500,000 prior to December 31, 2000.

   Prior to the Prodigy Acquisition, PSC utilized a network backbone and certain
POPs provided by Advantis and purchased computer equipment from IBM.  During the
year ended December 31, 1995 and the period January 1, 1996 through June 16,
1996, PSC paid Advantis $3,347,000 and $4,355,000, respectively, for network
services and paid IBM $13,686,000 and $4,893,000, respectively, for computer
equipment.  See Note 4 to the Consolidated Financial Statements of Prodigy
Services Company for a description of certain other transactions among PSC, IBM
and Sears.

CERTAIN TRANSACTIONS INVOLVING CARSO GLOBAL TELECOM, TELMEX AND GREG C. CARR

 FUNDING AGREEMENT

   In connection with the Prodigy Acquisition, the Company entered into a
Funding Agreement with Carso Global Telecom and Greg C. Carr on May 12, 1996
(the "Funding Agreement") under which Carso Global Telecom and Mr. Carr granted
the Company stock puts giving the Company the right to require Carso Global
Telecom and Mr. Carr to purchase shares of Common Stock with an aggregate
purchase price of up to $125,000,000 and $12,500,000, respectively, subject to
reduction in certain circumstances. The stock puts originally were exercisable
at a price of $6.00 per share until the earlier of November 12, 1997 or the
closing of the Company's initial public offering with gross proceeds of at least
$25,000,000. The Funding Agreement also contained a commitment from Carso Global
Telecom and Mr. Carr to invest $5,000,000 and $2,000,000, respectively, in the
Company's next private placement.  The Company also 

                                      72
<PAGE>
 
granted Carso Global Telecom an option, which was not exercised, to purchase the
Company's cellular telephone licenses and assets in the Ivory Coast and Guinea
for $69,000,000 prior to July 26, 1996. On October 31, 1996, the Funding
Agreement was amended to reduce the exercise price of the stock puts to $3.00
per share and the investment commitments of Carso Global Telecom and Mr. Carr in
the Company's next private placement were changed to $3,500,000 each. On March
18, 1997, the Funding Agreement was further amended as follows: (i) the amount
of Carso Global Telecom's stock put was reduced by $8,444,762, (ii) the amount
of Mr. Carr's stock put was increased by $8,500,000, (iii) Carso Global Telecom
and Mr. Carr agreed to the exercise of $65,000,000 and $15,000,000 of the stock
puts, respectively, and (iv) the expiration of the remaining stock puts was
extended to May 12, 1998. The proceeds of the foregoing $65,000,000 and
$15,000,000 of stock puts, together with the proceeds of their additional
financing commitments of $3,500,000 each, were paid to the Company in connection
with the October 1996 Placement described below under "-- Prior Equity
Financings". The final amount of the stock puts, after giving effect to certain
reductions contained in the Funding Agreement and the changes made by the March
18, 1997 amendment to the Funding Agreement, was $103,938,467 for Carso Global
Telecom and $20,990,533 for Mr. Carr. By October 1, 1997, the stock puts had
been fully exercised for 34,646,155 shares and 6,996,844 shares, respectively.
Pending expiration of the waiting period under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR Act"), applicable to certain of
the stock put exercises, (i) Carso Global Telecom loaned $71,500,000 to the
Company on an interest-free basis (subsequently converted into 28,833,333
shares), (ii) Carso Global Telecom caused Banco Inbursa, S.A. ("Banco Inbursa"),
an affiliate of Carso Global Telecom, to loan $13,650,000 to the Company at 9%
interest (subsequently repaid in full), (iii) Mr. Carr loaned $16,000,000 to the
Company on an interest-free basis (subsequently converted into 5,333,333 shares)
and (iv) Mr. Carr loaned $1,500,000 to the Company at 9% interest (subsequently
converted into 500,000 shares). All such loans were unsecured, and the proceeds
were used to finance the Company's operations, except that $40,000,000 of the
proceeds was used to repay indebtedness owed to Banco Inbursa under its prior
revolving line of credit. See "-- Loans from Banco Inbursa".

 WARRANTS

   In consideration of their commitments under the Funding Agreement, the
Company granted Carso Global Telecom and Mr. Carr (i) warrants to purchase
2,700,000 shares and 270,000 shares, respectively, of Common Stock for $3.00 per
share (the "Initial Warrants"), exercisable until December 31, 1996, and (ii)
warrants to purchase 2,000,000 shares and 1,000,000 shares, respectively, of
Common Stock for $9.00 per share (the "Additional Warrants"), exercisable until
the earlier of (a) the closing of the Company's initial public offering or (b)
November 12, 1997.  On October 2, 1996, Mr. Carr exercised his Initial Warrant
at the Company's request for $2.93 per share, reflecting a discount (based on
the interest rate paid under the Company's bank debt) from the original exercise
price in order to induce early exercise.  On December 27, 1996, Carso Global
Telecom exercised its Initial Warrant for $3.00 per share.  In connection with
the October 31, 1996 amendment of the Funding Agreement, Mr. Carr's Additional
Warrant was cancelled and the number of shares subject to Carso Global Telecom's
Additional Warrant was reduced from 2,000,000 to 1,000,000 and its exercise
price was reduced to $7.00 per share.  In consideration of the increased
financing commitments under the March 18, 1997 amendment to the Funding
Agreement, the Company granted Carso Global Telecom and Mr. Carr warrants (the
"March 1997 Warrants") to purchase 13,000,000 shares and 2,000,000 shares,
respectively, of Common Stock for $3.00 per share, exercisable prior to the
expiration of the stock puts, and Carso Global Telecom's Additional Warrant was
cancelled.  In consideration of certain interim financing commitments made by
Carso Global Telecom and Mr. Carr in October 1997, the exercise price of the
March 1997 Warrants was reduced from $3.00 per share to $1.00 per share.  Carso
Global Telecom exercised its March 1997 Warrant in April 1998.  Mr. Carr
subsequently transferred his March 1997 Warrant to a third party, who exercised
such March 1997 Warrant in May 1998.

 BOARD ARRANGEMENTS

   Mr. Carr was Chairman of the Board and a director of the Company from its
formation in June 1996 until his resignation in July 1998 and was also a
director of IW from March 1995 until January 1997.  The Company paid Mr. Carr an
annual fee of $135,000 from May 1996 until his resignation in recognition of the
fact that Mr. Carr's duties as Chairman of the Board were significantly greater
than the duties ordinarily assumed by a Chairman of the Board.

   In connection with the March 18, 1997 amendment of the Funding Agreement,
Carso Global Telecom and Mr. Carr agreed that, until the earlier of March 18,
2007 or one year after the Company's initial public offering with gross proceeds
of at least $25,000,000, (i) Carso Global Telecom would have the right to
designate 60% of the Company's directors, (ii) Mr. Carr would have the right to
designate 40% of the Company's directors, (iii) Mr. Carr would vote all shares
over which he (or any affiliate of Mr. Carr) exercised voting control in favor
of the election of the directors designated by Carso Global Telecom and (iv)
Carso Global Telecom would vote all shares over which it (or any affiliate of
Carso Global Telecom) exercised voting control in favor of the election of the
directors designated by Mr. Carr.  In connection with Telmex's purchase of
13,000,000 shares from Mr. Carr in August 1998, Carso Global Telecom and Mr.
Carr agreed to terminate the foregoing voting agreement, and Carso Global
Telecom agreed to continue, until the earlier of July 24, 1999 or Mr. Carr's
resignation as a director, to vote all shares over which it (or any of its
affiliates) exercised voting control in favor of the election of Mr. Carr as a
director. On July 24, 1998, Mr. Carr resigned as Chairman of the Board and, on
July 31, 1998, Mr. Carr resigned as a director of the Company.  See "-- Certain
Stock Purchases by Telmex".

 CERTAIN STOCK PURCHASES BY TELMEX

   In August 1998, Telmex purchased 13,000,000 shares of Common Stock from Mr.
Carr for $2.00 per share for an aggregate purchase price of $26,000,000.  If
Telmex, Carso Global Telecom, Prodigy or any of their affiliates purchases or
sells any Common Stock for more than $2.00 per share in a transaction
aggregating at least $500,000 on or before January 20, 1999 (a "Qualifying
Transaction"), Telmex will be required to pay to Mr. Carr an amount equal to (i)
13,000,000 multiplied by (ii) the difference between $2.00 and the price per
share in the Qualifying Transaction, subject to a maximum additional payment of
$.40 per share.  The Offering will be a Qualifying Transaction.  Upon the
closing of the Offering (at an assumed initial public offering price of $
per share), Telmex will be obligated to pay Mr. Carr $           pursuant to
this arrangement.  Mr. Carr concurrently purchased 1,154,625 shares at the same
price from family members and certain other stockholders.  Pending the
termination of the waiting period under the HSR Act applicable to Telmex's
purchase from Mr. Carr, Telmex loaned $26,000,000 to Mr. Carr. Such loan did not
bear interest and was secured by Mr. Carr's pledge to Telmex of 13,000,000
shares.  In connection with this transaction, the Company granted Mr. Carr
piggyback registration rights entitling Mr. Carr to participate in any
registered public offering in which Carso Global Telecom and/or Telmex proposes
to sell shares.  The registration rights agreement contains customary
underwriter cutback, indemnification and other provisions.  Telmex and Carso
Global Telecom also granted Mr. Carr certain co-sale rights to participate in
subsequent sales by Telmex or Carso Global Telecom, which rights will expire
upon the closing of the Offering.

   In August 1998, Telmex purchased 150,000 shares of Common Stock from Paul W.
DeLacey for $2.00 per share for an aggregate purchase price of $300,000.  Mr.
DeLacey served as President and Chief Executive Officer of the Company from June
1996 until September 1997 and as a director of the Company from June 1996 until
July 1998.  Mr. DeLacey concurrently purchased 25,000 shares at the same price
from family members.  Pending the termination of the waiting period under the
HSR Act applicable to Telmex's purchase from Mr. DeLacey, Telmex loaned $300,000
to Mr. DeLacey.  Such loan did not bear interest and was secured by Mr.
DeLacey's pledge to Telmex of 150,000 shares.  In connection with this
transaction, Mr. DeLacey resigned as a director on July 24, 1998.

 LOANS FROM BANCO INBURSA

   In June 1996, Banco Inbursa agreed to provide the Company with a $50,000,000
revolving line of credit with an original maturity of June 13, 1997.  In June
1996, the Company borrowed $48,000,000 in order to pay the cash portion of the
purchase price for the Prodigy Acquisition and related expenses and subsequently
borrowed the remaining $2,000,000.  In March 1997, the Company repaid
$40,000,000 to Banco Inbursa.  See "-- Funding Agreement".  In June 1997, Banco
Inbursa agreed to extend the line of credit for $10,000,000 until January 31,
1998.  Advances under the line of credit bore interest at the prime rate plus
one-half percentage point.  Between February 1998 and July 1998, Banco Inbursa
made additional advances to the Company in the aggregate amount of $32,100,000
to fund operations; such loans bore 9% interest and were due December 31, 1999.
In late July 1998, the Company repaid all $32,100,000 then owed to Banco
Inbursa.  Banco Inbursa also made interim loans to the Company pending the
closing of certain equity financings, all of which loans have been repaid.  See
"-- Prior Equity Financings".

   In June 1996, Carso Global Telecom and Mr. Carr pledged 7,000,000 shares and
10,000,000 shares of Common Stock, respectively, owned by them to secure amounts
outstanding under the Banco Inbursa line of credit.  In connection with the
October 31, 1996 amendment of the Funding Agreement, Mr. Carr agreed to continue
his stock pledge until June 13, 1998 to secure a new line of credit from a
United States bank or other debt financing to replace the Banco Inbursa line of
credit.  In October 1997, Mr. Carr agreed to pledge 7,500,000 shares of Common
Stock to secure advances of $3,750,000 from Banco Inbursa to the Company until
the closing of the Company's rights offering in December 1997.  All stock
pledges of Carso Global Telecom and Mr. Carr were released in July 1998.

 LOANS FROM GREG C. CARR

   In November and December 1996, Mr. Carr loaned $6,000,000 to the Company.
Such loans bore interest at the prime rate plus 1 1/4 percentage points and were
repaid with interest on January 2, 1997.

   From March 31, 1995 to May 15, 1995, Mr. Carr provided a revolving line of
credit of $1,250,000 to the Company.  See "-- Prior Corporate History -- ACI
Merger".  As of May 15, 1995, Mr. Carr converted the advances and accrued
interest then outstanding ($730,000 in total) into Common Stock at $2.50 per
share.  From November 15, 1995 to June 12, 1996, Mr. Carr provided a revolving
line of credit of $4,500,000 to the Company.  Effective as of March 31, 1996,
Mr. Carr converted $3,000,000 in advances into 1,000,000 shares of Common Stock
at $3.00 per share in connection with the November 1995 Placement described
below under "-- Prior Equity Financings".  Effective as of June 12, 1996, Mr.
Carr converted the remaining $1,500,000 in advances into 500,000 shares of
Common Stock at $3.00 per share.  Advances under both facilities were secured by
all of the Company's assets, bore interest at a floating interest rate based on
the prime rate and were used to finance the Company's operations.  Upon
establishment of the $4,500,000 facility, the Company paid Mr. Carr a commitment
fee equal to 1% of the total facility ($45,000) through the issuance of 15,000
shares of Common Stock valued at $3.00 per share.

PRIOR EQUITY FINANCINGS

   In August 1998, Telmex purchased 24,500,000 shares of Common Stock from the
Company for $2.00 per share for aggregate gross proceeds of $49,000,000, and in
July 1998 Carso Global Telecom purchased 5,500,000 shares of Common Stock from
the Company for $2.00 per share for aggregate gross proceeds of $11,000,000.
Pending the termination of the applicable waiting period under the HSR Act,
Telmex's investment in the Company was represented by an unsecured, interest-
free loan to the Company.

   In November 1997, the Company made a rights offering in which each
stockholder of the Company was entitled to purchase one share of Common Stock at
a price of $1.00 per share for each one share held 

                                      75
<PAGE>
 
as of October 10, 1997. The offering price was determined by the Company's Board
of Directors to equal the fair market value of the Common Stock at that time
upon consideration of certain analyses undertaken by a financial advisor as to
the range within which the purchase price would be fair to the Company from a
financial point of view and after consideration of other factors. On December
19, 1997, the Company closed the rights offering by issuing an aggregate of
50,561,915 shares to 36 stockholders of the Company, including 49,543,822 shares
to Carso Global Telecom and 500,000 shares to Mr. Carr. Mr. Carr paid the
purchase price for his shares through the conversion of $500,000 of prior
advances to the Company without interest. In payment for its 49,543,822 shares,
Carso Global Telecom (i) was credited with $4,000,000 by reason of the issuance
of the IBM/Sears LC, (ii) paid $13,750,000 directly to Banco Inbursa on the
Company's behalf in repayment of $13,750,000 of indebtedness owed by the Company
to Banco Inbursa (see "--Loans from Banco Inbursa") and (iii) paid the remaining
$31,793,822 to the Company. Each calendar quarter, Carso Global Telecom is
required to pay the Company an amount equal to $333,333 less any draws on the
IBM/Sears LC during such quarter until the entire $4,000,000 has been paid to
the Company or drawn under the IBM/Sears LC. As of June 30, 1998, Carso Global
Telecom had paid $666,666 pursuant to such commitment and the IBM/Sears LC had
been reduced to $3,333,334.

   Between October 1996 and May 1997, the Company received aggregate gross
proceeds of $88,843,235 from the private placement (the "October 1996
Placement") of 29,614,412 shares of Common Stock for $3.00 per share.  In the
October 1996 Placement, Carso Global Telecom and Mr. Carr invested $68,500,000
and $18,500,000, respectively, through exercises of the stock puts and the
financing commitments contained in the Funding Agreement, and Mr. Pillar
invested $30,000.  See "-- Funding Agreement".  The Company also granted a
warrant to purchase 68,056 shares of Common Stock for $3.00 per share,
exercisable at any time prior to December 13, 2001, to a placement agent in the
October 1996 Placement.

   Pursuant to an agreement dated April 11, 1996, Carso Global Telecom purchased
7,000,000 shares of Common Stock from the Company for $3.00 per share (for
aggregate gross proceeds of $21,000,000) on various dates between March 1996 and
September 1996.

   Between November 1995 and March 1996, the Company received aggregate gross
proceeds of $7,376,508 from the private placement (the "November 1995
Placement") of 2,458,836 shares of Common Stock for $3.00 per share.  Mr. Carr
purchased 1,000,000 shares in the November 1995 Placement for $3,000,000 upon
the conversion of advances made by him to the Company under a line of credit.
See "-- Loans from Greg C. Carr".

   Between May 1995 and October 1995, the Company received aggregate gross
proceeds of $3,081,250 from the private placement (the "May 1995 Placement") of
1,232,500 shares of Common Stock for $2.50 per share.  Mr. Carr purchased
400,000 shares in the May 1995 Placement for $1,000,000.

   Between October 1994 and February 1995, the Company received aggregate gross
proceeds of $907,456 from the private placement (the "October 1994 Placement")
of 453,728 shares of Series A Convertible Preferred Stock ("Series A Stock") for
$2.00 per share.  On March 31, 1995, each share of Series A Stock was
reclassified and changed into 1.25 shares of Common Stock (for an aggregate of
567,160 shares of Common Stock), resulting in an effective purchase price for
the investors in the October 1994 Placement of $1.60 per share of Common Stock.
The rate at which Series A Stock was exchanged for Common Stock was intended to
compensate the holders of Series A Stock for the value of the liquidation
preference they relinquished upon the reclassification of their shares into
Common Stock.

PRIOR CORPORATE HISTORY

 COMSTAR TRANSACTION

   The Company's predecessor, IW, was formed in Delaware in May 1994 to develop
and operate cellular telephone systems in Africa.  On August 10, 1994, IW
acquired all of the assets of Comstar Cellular Network, Inc. and assumed
Comstar's outstanding accounts payable.  At the time of the acquisition,
Comstar's corporate records were incomplete and there had been an overissuance
of Comstar's common stock.  Comstar also required an immediate cash infusion in
order to complete the activities required to convert the two provisional
communications licenses it held in Africa into definitive licenses. In exchange
for Comstar's assets, IW issued to Comstar all then outstanding common stock of
IW, which Comstar then distributed as a liquidating dividend to the holders of
certificates for common stock of Comstar.  Each holder of a certificate for
common stock of Comstar was required to acknowledge and accept the terms of the
Comstar acquisition and release Comstar and IW from all claims which such holder
may have had against either Comstar or IW.  The terms of the Comstar acquisition
were accepted by the holders of 98% of the certificates for common stock of
Comstar (representing 78% of the number of shares covered by outstanding
certificates for common stock of Comstar), and an aggregate of 21,636,850 shares
of IW common stock were issued to the former holders of Comstar certificates.
Three persons chose not to participate in the Comstar acquisition and received
no IW shares.  See "Business -- Legal Proceedings".  In March 1995, Comstar was
dissolved under Nevada law.  The Company believes that the Comstar acquisition
provided the holders of certificates for common stock of Comstar with the
opportunity to acquire equity participation, without further investment, in a
properly constituted corporation without the corporate irregularities or claims
of creditors faced by Comstar and in substantially the same proportions as they
would have had in Comstar had their certificates been validly issued.

 ACI MERGER

   On March 31, 1995, African Communications Incorporated ("ACI") was merged
with and into IW (the "ACI Merger").  Prior to the ACI Merger, IW and ACI had
jointly evaluated certain African markets and established IW's initial foreign
subsidiaries.  ACI had no material assets or liabilities other than its equity
interests in the initial foreign subsidiaries and loans of approximately
$450,000 to IW and certain of its foreign subsidiaries.  Immediately prior to
the ACI Merger, ACI assigned these loans to Mr. Carr (who was then ACI's sole
stockholder), and Mr. Carr agreed to make approximately $800,000 in additional
loans available to IW.  See "-- Loans from Greg C. Carr".  In the ACI Merger,
Mr. Carr received 11,162,255 shares of common stock of IW, representing 33.8% of
the outstanding common stock immediately after the ACI Merger and 32.3% of the
then outstanding common stock on a fully-diluted basis.  The terms of the ACI
Merger were negotiated to reflect the fact that the initial foreign subsidiaries
were owned by IW and ACI in a two-to-one ratio.

 DISPOSITIONS OF FORMER INTERNATIONAL OPERATIONS

   Effective January 27, 1997, the Company sold all of IW's issued and
outstanding capital stock to an acquisition corporation (the "Cellular Buyer")
formed by Terrance P. Dillon, a former director and principal stockholder of the
Company and IW.  At the time of the sale, IW's assets consisted of cellular
communications licenses and license applications in certain African countries
and the associated rights and assets used in the Company's cellular telephone
operations. The original purchase price consisted of (i) the surrender of
5,571,429 shares of Common Stock of the Company (valued by the parties at $6.75
per share), (ii) a Promissory Note (the "Cellular Note") in the original
principal amount of $21,500,000 (including $1,500,000 in reimbursement of
capital expenditures made by the Company for the benefit of IW) and (iii) the
cancellation of options to purchase 500,000 shares of Common Stock of the
Company. In October 1997, the Cellular Buyer surrendered an additional 2,294,321
shares of Common Stock of the 

                                      77
<PAGE>
 
Company held by the Cellular Buyer (valued by the parties at $3.00 per share) to
reduce its unpaid obligations under the Cellular Note and to satisfy unpaid
indemnification obligations owed to the Company. As of June 30, 1998,
$17,009,000 in principal amount and accrued interest was outstanding under the
Cellular Note. Due to uncertainties associated with the efforts of the Cellular
Buyer to obtain financing, the Cellular Note has been recorded in the Company's
accounts at a book value of zero.

   The Company currently owns Africa Online, Inc. ("AFOL"), an ISP operating in
various African countries.  The Company has agreed in principle to sell AFOL for
$2,815,000 in cash, of which $1,407,000 will be placed in escrow for six months
to secure the Company's indemnification obligations to the buyer. The
transaction is scheduled to close in September 1998 but is subject to certain
conditions, and there can be no assurance that the closing will occur as
scheduled.  If AFOL is not sold as scheduled, the Company intends to seek
another buyer for AFOL or wind-down its operations.

   The Company formerly participated in several joint ventures which offered
Internet, online, voice messaging and fax messaging services in China.  In March
1998, the Company terminated its Chinese joint ventures and operations.  See
Note 5 to the Company's Consolidated Financial Statements.

(1) Beneficial ownership is determined in accordance with the rules of the
    Securities and Exchange Commission, and is not necessarily indicative of
    beneficial ownership for any other purpose. Under such rules, beneficial
    ownership includes any shares as to which the individual or entity has sole
    or shared voting power or investment power and any shares as to which the
    individual or entity has the right to acquire within 60 days after August
    31, 1998 through the exercise of any stock option, warrant or other right
    (but such shares are not deemed outstanding for purposes of calculating the
    percentage ownership of any other person). The inclusion herein of any such
    shares, however, does not constitute an admission that the named stockholder
    is a direct or indirect beneficial owner of such shares. Unless otherwise
    indicated, each person or entity named in the table has sole voting power
    and investment power (or shares such power with his or her spouse) with
    respect to all shares of capital stock listed as owned by such person or
    entity.

(2) Shares to be beneficially owned after the Offering give pro forma effect to
    the Offering and the issuance to IBM and Sears of an aggregate of     shares
    upon the closing of the Offering (at an assumed initial public offering
    price of $     per share) pursuant to the conversion of the Contingent Notes
    held by them. See "Corporate History and Certain Transactions -- Acquisition
    of Prodigy Services Company" and Notes 1, 4 and 9 to the Company's
    Consolidated Financial Statements.

(3) Excludes the listed shares held by Telmex, with respect to which Carso
    Global Telecom may be deemed to be the beneficial owner.  In June 1996,
    Carso Global Telecom was spun-off from Grupo Carso, a holding company with
    interests in the tobacco, mining, metallurgical and paper industries, in the
    operation of restaurants and department stores, in the production of copper,
    copper alloys, copper cable, aluminum wire and tires, and in Mexican banks
    and brokerage houses.  Mr. Carlos Slim Helu, a Mexican citizen, and certain
    members of his immediate family, directly and through their ownership of a
    majority of the voting and economic interests in two trusts, own a majority
    of the outstanding voting equity securities of Carso Global Telecom, Grupo
    Carso and Grupo Financiero.  Mr. Slim may be deemed to be the beneficial
    owner of all Common Stock of the Company held by Carso Global Telecom and
    Telmex.  See "Risk Factors -- Control of the Company and Potential Conflicts
    of Interest".   As used herein with respect to the Company, all references
    to Carso Global Telecom mean and include Grupo Carso prior to the date Carso
    Global Telecom was spun-off from Grupo Carso.  The business address of Carso
    Global Telecom and Mr. Slim is Paseo de las Palmas, #736, Col. Lomas de

    closing of the Offering, 75,000 additional shares of Common Stock subject to
    stock options that will become exercisable upon the closing of the Offering.

(6) Excludes the listed shares held by Carso Global Telecom and Telmex, with
    respect to which such person may be deemed to be the beneficial owner.  If
    such shares were included, the number of shares held by all directors and
    executive officers as a group would be 156,204,544, or    % of the
    outstanding shares, prior to the Offering and 156,354,544, or    % of the
    outstanding shares, following the Offering.  See "Management".

(7) Pre-Offering figures include 275,000 shares of Common Stock subject to
    outstanding stock options that are exercisable within 60 days after August

                          DESCRIPTION OF CAPITAL STOCK

   Upon the closing of the Offering, the authorized capital stock of the Company
will consist of       shares of Common Stock, $.01 par value per share, and
shares of Preferred Stock, $.01 par value per share.  As of August 31, 1998,
there were outstanding (i) 180,225,727 shares of Common Stock held by 395

shares of Common Stock at a weighted-average exercise price of $1.56 per share,
(iii) warrants to purchase an aggregate of 437,389 shares of Common Stock at a
weighted-average exercise price of $2.76 per share and (iv) the Contingent Notes
and Contingent Warrants held by IBM and Sears.  Upon the closing of the Offering
(at an assumed initial public offering price of $       per share), (i) there
will be outstanding        shares of Common Stock, after giving effect to the
conversion of the Contingent Notes held by IBM and Sears into an aggregate of
shares of Common Stock, and (ii) the Contingent Warrants will be exercisable for
an aggregate of           shares of Common Stock at an exercise price of $
per share until the third anniversary of the Closing.  See "Management -- Stock
Plans" and "Corporate History and Certain Transactions -- Acquisition of Prodigy
Services Company".

   The following summary of certain provisions of the Company's Common Stock,
Preferred Stock, Certificate of Incorporation and By-laws, as in effect upon the
closing of the Offering, is not intended to be complete and is qualified by
reference to the provisions of applicable law and to the Company's Certificate
of Incorporation and By-laws included as exhibits to the Registration Statement
of which this Prospectus is a part.  See "Additional Information".

COMMON STOCK

   Holders of Common Stock are entitled to one vote for each share held on all
matters submitted to a vote of stockholders and do not have cumulative voting
rights.  Accordingly, holders of a majority of the shares of Common Stock
entitled to vote in any election of directors may elect all of the directors
standing for election.  Holders of Common Stock are entitled to receive ratably
such dividends, if any, as may be declared by the Board of Directors out of
funds legally available therefor, subject to any preferential dividend rights of
outstanding Preferred Stock.  Upon the liquidation, dissolution or winding up of
the Company, the holders of Common Stock are entitled to receive ratably the net
assets of the Company available after the payment of all debts and other
liabilities and subject to the prior rights of any outstanding Preferred Stock.
Holders of Common Stock have no preemptive, subscription, redemption or
conversion rights.  The outstanding shares of Common Stock are, and the shares
offered in the Offering will be, when issued and paid for, fully paid and
nonassessable.  The rights, preferences and privileges of holders of Common
Stock are subject to, and may be adversely affected by, the rights of the
holders of shares of any series of Preferred Stock which the Company may
designate and issue in the future.  Upon the closing of the Offering, certain
holders of Common Stock have the right to require the Company to effect the
registration of their shares of Common Stock in certain circumstances.  See
"Shares Eligible for Future Sale -- Registration Rights".

PREFERRED STOCK

   The Board of Directors is authorized, without any further action by the
Company's stockholders, to designate and issue shares of Preferred Stock in one
or more series and to fix the rights and preferences thereof, including the
voting, dividend, conversion, redemption and liquidation rights and preferences.
The issuance of Preferred Stock, while providing desirable flexibility in
connection with possible financings, acquisitions and other corporate purposes,
could adversely affect the rights of the holders of Common Stock and, under
certain circumstances, be used as a means of discouraging, delaying or
preventing a change of control or acquisition of the Company.  The Company has
no present plans to issue any Preferred Stock.

DELAWARE ANTI-TAKEOVER STATUTE

   Section 203 of the Delaware General Corporation Law ("DGCL") is applicable to
publicly-held corporations organized under the laws of Delaware, including the
Company.  Subject to certain exceptions set forth therein, Section 203 of the
DGCL provides that a corporation shall not engage in any business combination
with any "interested stockholder" for a three-year period following the date
that such stockholder becomes an interested stockholder unless (a) prior to such
date, the board of directors of the corporation approved either the business
combination or the transaction which resulted in the stockholder becoming an
interested stockholder, (b) upon consummation of the transaction which resulted
in the stockholder becoming an interested stockholder, the interested
stockholder owned at least 85% of the voting stock of the corporation
outstanding at the time the transaction commenced (excluding certain shares) or
(c) on or subsequent to such date, the business combination is approved by the
board of directors of the corporation and by the affirmative vote of at least
two-thirds of the outstanding voting stock which is not owned by the interested
stockholder.  Except as specified therein, an interested stockholder is defined
to mean any person that (i) is the owner of 15% or more of the outstanding
voting stock of the corporation, or (ii) is an affiliate or associate of the
corporation and was the owner of 15% or more of the outstanding voting stock of
the corporation at anytime within three years immediately prior to the relevant
date and the affiliates and associates of such person referred to in (i) or (ii)
of this sentence. Under certain circumstances, Section 203 of the DGCL makes it
more difficult for an interested stockholder to effect various business
combinations with a corporation for a three-year period, although the
stockholders may, by adopting an amendment to the corporation's certificate of
incorporation or by-laws, elect not to be governed by this section, effective
twelve months after adoption.  The Company's Certificate of Incorporation and
By-laws do not exclude the Company from the restrictions imposed under Section
203 of the DGCL.

LIMITATION ON LIABILITY AND INDEMNIFICATION OF DIRECTORS

   The Certificate of Incorporation contains certain provisions permitted under
the DGCL relating to the liability of directors.  The provisions eliminate a
director's liability for monetary damages for a breach of fiduciary duty, except
in certain circumstances involving wrongful acts, such as the breach of a
director's duty of loyalty or acts or omissions which involve intentional
misconduct or a knowing violation of law.  Further, the Certificate of
Incorporation contains provisions to indemnify the Company's directors and
officers to the fullest extent permitted by the DGCL.  The Company believes that
these provisions will assist the Company in attracting and retaining qualified
individuals to serve as directors.

TRANSFER AGENT AND REGISTRAR

   The transfer agent and registrar for the Common Stock is American Stock
Transfer & Trust Company.

                        SHARES ELIGIBLE FOR FUTURE SALE

   Prior to the Offering, there has been no public market for the securities of
the Company.  Upon completion of the Offering, based upon the number of shares
outstanding on the date of this Prospectus and after giving pro forma effect to
the conversion upon the closing of the Offering (at an assumed initial public
offering price of $           per share) of the Contingent Notes held by IBM and
Sears into an aggregate of       shares of Common Stock, there will be
shares of Common Stock of the Company outstanding (assuming no exercise of the
Underwriters' over-allotment option or outstanding warrants or options of the
Company).  Of these shares, the          shares sold in the Offering will be
freely tradeable without restriction or further registration under the
Securities Act, except that any shares purchased by "affiliates" of the Company,
as that term is defined in Rule 144 ("Rule 144") under the Securities Act
("Affiliates"), may generally only be sold in compliance with the limitations of
Rule 144 described below.

SALES OF RESTRICTED SHARES

   The remaining                 shares of Common Stock are deemed "restricted
securities" under Rule 144.  Of the restricted securities, approximately
shares of Common Stock, which are not subject to the 180-day lock-up agreements
(the "Lock-up Agreements") with the Representatives of the Underwriters, will be
eligible for immediate sale in the public market pursuant to Rule 144(k) under
the Securities Act.  Approximately           additional shares of Common Stock,
which are not subject to Lock-up Agreements, will be eligible for sale in the
public market in accordance with Rule 144 or Rule 701 under the Securities Act
beginning 90 days after the date of this Prospectus.  Upon expiration of the
Lock-up Agreements 180 days after the date of this Prospectus, approximately
additional shares of Common Stock will be available for sale in the public
market, subject to the provisions of Rule 144 under the Securities Act.

   The Company and certain stockholders of the Company (including Carso Global
Telecom, Telmex, IBM, Sears and all directors and executive officers of the
Company) who will hold, upon consummation of the Offering at an assumed initial
public offering price of $              per share, an aggregate of approximately
shares of Common Stock, have agreed, pursuant to the Lock-up Agreements, not to
offer, sell, contract to sell or otherwise dispose of any Common Stock, or any
options, warrants or other securities convertible into or exercisable for Common
Stock, for 180 days after the date of this Prospectus without the prior written
consent of Bear, Stearns & Co. Inc. except, in the case of the Company, for the
shares of Common Stock to be issued in connection with the Offering or pursuant
to employee benefit plans existing on the date of this Prospectus and, in the
case of the executive officers, directors and existing stockholders, certain
permitted transfers to related parties that agree to be bound by the foregoing
restrictions and certain permitted sales of shares acquired in the open market
following the completion of the Offering.

   In general, under Rule 144 as currently in effect, beginning 90 days after
the effective date of the Registration Statement of which this Prospectus is a
part, a stockholder, including an Affiliate, who has beneficially owned his or
her restricted securities (as that term is defined in Rule 144) for at least one
year from the later of the date such securities were acquired from the Company
or (if applicable) the date they were acquired from an Affiliate is entitled to
sell, within any three-month period, a number of such shares that does not
exceed the greater of 1% of the then outstanding shares of Common Stock
(approximately           shares immediately after the Offering) or the average
weekly trading volume in the Common Stock during the four calendar weeks
preceding the date on which notice of such sale was filed under Rule 144,
provided certain requirements concerning availability of public information,
manner of sale and notice of sale are satisfied.  In addition, under Rule
144(k), if a period of at least two years has elapsed between the later of the
date restricted securities were acquired from the Company or (if applicable) the
date they were acquired from an Affiliate of the Company, a stockholder who is
not an Affiliate of the Company at the time of sale and has not been an
Affiliate of the Company for at least three months prior to the sale 

                                      84
<PAGE>
 
is entitled to sell the shares immediately without compliance with the foregoing
requirements under Rule 144.

   Securities issued in reliance on Rule 701 (such as shares of Common Stock
acquired pursuant to the exercise of certain options granted under the Company's
stock plans) are also restricted securities and, beginning 90 days after the
effective date of the Registration Statement of which this Prospectus is a part,
may be sold by stockholders other than Affiliates of the Company subject only to
the manner of sale provisions of Rule 144 and by Affiliates under Rule 144
without compliance with its one-year holding period requirement.

OPTIONS

   The Company intends to file registration statements on Form S-8 under the
Securities Act to register all shares of Common Stock issuable under the Option
Plan and the Purchase Plan.  The Company intends to file registration statements
on Form S-8 with respect to the shares of Common Stock issuable under the Option
Plan and the Purchase Plan as early as the day of the consummation of the
Offering.  Shares issued upon the exercise of stock options after the effective
date of the Form S-8 registration statements will be eligible for resale in the
public market without restriction, subject to Rule 144 limitations applicable to
Affiliates and the Lock-Up Agreements noted above, if applicable.

REGISTRATION RIGHTS

   In connection with the Company's acquisition of Prodigy Services Company from
IBM and Sears in June 1996, the Company issued to IBM and Sears the Contingent
Notes and Contingent Warrants.  IBM and Sears hold customary piggyback and
demand registration rights, at Prodigy's expense, with respect to the Common
Stock issuable upon conversion of the Contingent Notes and exercise of the
Contingent Warrants.  See "Corporate History and Certain Transactions  --
Acquisition of Prodigy Services Company". Upon the closing of the Offering (at
an assumed initial public offering price of $       per share), IBM and Sears
will each (i) receive        shares of Common Stock pursuant to the conversion
of its Contingent Note and (ii) hold a Contingent Warrant to purchase
shares of Common Stock for $         per share (subject to customary anti-
dilution adjustments) at any time prior to the third anniversary of the
Offering.  In addition, Greg C. Carr holds piggyback registration rights with
respect to         shares of Common Stock held by him.  See "Corporate History
and Certain Transactions -- Certain Transactions Involving Carso Global Telecom,
Telmex and Greg C. Carr -- Certain Stock Purchases by Telmex".

EFFECT OF SALES OF SHARES

   Prior to the Offering, there has been no public market for the Common Stock,
and no prediction can be made as to the effect, if any, that market sales of
shares of Common Stock or the availability of shares for sale will have on the
market price of the Common Stock prevailing from time to time.  Nevertheless,
sales of significant numbers of shares of the Common Stock in the public market
could adversely affect the market price of the Common Stock and could impair the
Company's future ability to raise capital through an offering of its equity
securities.

Brown Whelan & Company, LLC are acting as representatives (the
"Representatives") and Wit Capital Corporation is facilitating online

the following respective number of shares of Common Stock at the initial public
offering price less underwriting discounts and commissions set forth on the
cover page of this Prospectus:

                                                                    NUMBER

   The Underwriting Agreement provides that the obligations of the Underwriters
are subject to certain conditions precedent and that the Underwriters will
purchase all of the shares of Common Stock offered hereby if any of such shares
are purchased.

   The Company has been advised by the Representatives that the Underwriters
propose to offer the shares of Common Stock to the public at the initial public
offering price set forth on the cover page of this Prospectus and to certain
dealers at such price less a concession not in excess of $     per share.  The
Underwriters may allow, and such dealers may re-allow, a concession to certain
other dealers not in excess of $         per share.  After commencement of the
initial public offering, the offering price and other selling terms may be
changed by the Representatives.

   The Company has granted the Underwriters an option, exercisable not later
than 30 days after the date of this Prospectus, to purchase up to
additional shares of Common Stock at the initial public offering price less the
underwriting discounts and commissions set forth on the cover page of this
Prospectus.  To the extent that the Underwriters exercise this option, each
Underwriter will have a firm commitment, subject to certain conditions, to
purchase approximately the same percentage thereof which the number of shares of
Common Stock to be purchased by it in the above table bears to the
shares of Common Stock initially offered hereby and the Company will be
obligated, pursuant to the option, to sell such shares to the Underwriters.  The
Underwriters may exercise such option only to cover over-allotments made in
connection with the sale of the Common Stock offered hereby.  If purchased, the
Underwriters will offer such additional shares on the same terms as those on
which the          shares are being offered.

   The Underwriting Agreement contains covenants of indemnity and contribution
between the Underwriters and the Company regarding certain liabilities,
including liabilities under the Securities Act.

   To facilitate the Offering of the Common Stock, the Underwriters may engage
in transactions that stabilize, maintain or otherwise affect the market price of
the Common Stock.  Specifically, the Underwriters may over-allot shares of the
Common Stock in connection with this Offering, thereby 

                                      86
<PAGE>
 
creating a short position in the Underwriters' syndicate account. Additionally,
to cover such over-allotments or to stabilize the market price of the Common
Stock, the Underwriters may bid for, and purchase, shares of the Common Stock in
the open market. Any of these activities may maintain the market price of the
Common Stock at a level above that which might otherwise prevail in the open
market. The Underwriters are not required to engage in these activities, and, if
commenced, any such activities may be discontinued at any time. The
Representatives, on behalf of the Underwriters, also may reclaim selling
concessions allowed to an Underwriter or dealer, if the syndicate repurchases
shares distributed by that Underwriter or dealer.

   The Underwriters have reserved for sale at the initial public offering price
up to           shares of Common Stock for sale to certain directors, officers
and employees, friends and family of the Company who have expressed an interest
in purchasing such shares of Common Stock in the Offering. Such persons are
expected to purchase, in the aggregate, not more than     % of the Common Stock
offered in the Offering. The number of shares available for sale to the general
public in the Offering will be reduced to the extent such persons purchase such
reserved shares. Any reserved shares not so purchased will be offered to the
general public on the same basis as other shares offered hereby.

   The Underwriters, at the request of the Company, have reserved for sale at
the initial public offering price up to           shares of Common Stock to
current or prior subscribers to the Company's services who express an interest
in purchasing such shares. The sale of such shares will be made by Wit Capital
Corporation (acting as e-Manager) in the Offering. Purchases of the reserved
shares are to be made through an account at Wit Capital Corporation in
accordance with Wit Capital Corporation's procedures for opening an account and
transacting in securities. Any reserved shares not purchased by subscribers to
the Company's services will be offered by the Underwriters on the same basis as
other shares offered hereby.

   The Underwriters have informed the Company that they do not expect to confirm
sales to any accounts over which they exercise discretionary authority.

   The Company and certain stockholders of the Company (including Carso Global
Telecom, Telmex, IBM, Sears and all directors and executive officers of the
Company) who will hold, upon consummation of the Offering at an assumed initial
public offering price  of $         per share, an aggregate of approximately
shares of Common Stock, have agreed, pursuant to the Lock-up Agreements, not to
offer, sell, contract to sell or otherwise dispose of any Common Stock, or any
options, warrants or other securities convertible into or exercisable for Common
Stock, for 180 days after the date of this Prospectus without the prior written
consent of Bear, Stearns & Co. Inc. except, in the case of the Company, for the
shares of Common Stock to be issued in connection with the Offering or pursuant
to employee benefit plans existing on the date of this Prospectus and, in the
case of the executive officers, directors and existing stockholders, for the
shares of Common Stock sold in connection with the Offering (if any), sales or
dispositions to the Company, certain permitted transfers to related parties that
agree to be bound by the foregoing restrictions and certain permitted sales of
shares acquired in the open market following the completion of the Offering.

   ING Baring Furman Selz LLC acted as the Company's financial advisor in the
Prodigy Acquisition and was paid a fee of $750,000.  The Company also agreed
that if it undertook an initial public offering prior to June 17, 1998, ING
Baring Furman Selz LLC would be permitted to act as a co-manager of such
offering and receive per-share compensation no less favorable than the per-share
compensation paid to other underwriters of the offering.  The selection of ING
Baring Furman Selz LLC as one of the Representatives in the Offering was not
made pursuant to these arrangements.  See "Corporate History and Certain
Transactions -- Acquisition of Prodigy Services Company".

   Wit Capital Corporation acted as financial advisor in connection with the
Company's issuance of 5,500,000 shares of Common Stock to Carso Global Telecom
in July 1998 and 24,500,000 shares of Common 

                                      87
<PAGE>
 
Stock to Telmex in August 1998 and was paid a fee of $50,000. See "Corporate
History and Certain Transactions -- Prior Equity Financings".

   Prior to this Offering, there was no public market for the Common Stock.
Consequently, the initial public offering price for the Common Stock was
determined by negotiations between the Company and the Representatives.  Among
the factors considered in such negotiations were the history of, and the
prospects for, the Company's business and the industry in which it competes, an
assessment of the Company's management, the Company's past and present
operations and financial results, the prospects for earnings of the Company, the
present state of the Company's development, the general condition of the
securities markets at the time of the Offering and the price-earnings ratios and
market prices of securities of comparable companies at the time of the Offering.
There can be no assurance that an active trading market will develop for the
Common Stock or that the Common Stock will trade in the public market subsequent
to the Offering at or above the initial public offering price.

                                 LEGAL MATTERS

   The validity of the shares of Common Stock offered hereby will be passed upon
for the Company by Hale and Dorr LLP, Boston, Massachusetts.  A partner of Hale
and Dorr LLP owns 30,000 shares of the Company's Common Stock.  Certain legal
matters relating to the Offering will be passed upon for the Underwriters by
O'Sullivan Graev & Karabell, LLP, New York, New York.

                        REPORT OF INDEPENDENT ACCOUNTANTS



To the Board of Directors and Shareholders of
Prodigy Communications Corporation:

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations and stockholders' equity (deficit) and of
cash flows present fairly, in all material respects, the financial position of
Prodigy Communications Corporation (formerly Prodigy, Inc.) and its subsidiaries
at December 31, 1996 and 1997, and the results of their operations and their
cash flows for each of the two years in the period ended December 31, 1997, in
conformity with generally accepted accounting principles. These financial
statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

Notes to Consolidated Financial Statements

1.   Basis of Presentation

     Prodigy Communications Corporation (the "Company") is a leading nationwide
     Internet Service Provider ("ISP"). The Company is controlled by Carso
     Global Telecom, S.A. de C.V. ("Carso Global Telecom") through a majority
     voting equity interest in the Company's common stock. The Company was
     formed in June 1996, under the name Prodigy, Inc., to acquire Prodigy
     Services Company ("PSC") and to hold International Wireless Incorporated
     ("IW") and other communications interests. All outstanding common stock of
     IW was converted into common stock of the Company on a one-for-one basis in
     June 1996. The assets and liabilities of IW were carried over to the
     Company at historical cost as the respective shareholders maintained their
     relative ownership percentages existing immediately prior to the
     conversion. Accordingly, the financial statements prior to the acquisition
     of Prodigy Services on June 17, 1996, consist solely of IW. IW was
     incorporated on May 23, 1994, to develop and operate cellular telephone
     systems in Africa. IW's other communications interests consisted of Africa
     Online, Inc. (see Note 5 - Dispositions), a wholly-owned subsidiary engaged
     in interest access and online services in Africa, an equity investment in
     Global Enterprise Services, Inc. (see Note 4-Acquisitions) and an equity
     investment in a start-up joint venture in China (see Note 5 -
     Dispositions).

     Since the acquisition of PSC, the Company has been in the midst of a major
     transformation, both domestically and internationally. In the United
     States, the Company launched its open standards based Internet access
     service ("Prodigy Internet") in October 1996. The Company's cellular
     telephone assets and operations were sold in January 1997. In 1997, the
     Company determined that its primary focus will be as an ISP and decided to
     discontinue the production of its own content for Prodigy Internet. The
     Company plans to sell its African operations and has negotiated a
     settlement of its liabilities in connection with the closing of its Asian
     operations (see Note 5 - Dispositions).

     The acquisition of PSC was accounted for as a purchase. Accordingly, the
     results of operations of PSC since the date of acquisition, June 17, 1996,
     are included in the accompanying consolidated statements of operations for
     the year ended December 31, 1996. The consolidated statements of operations
     and cash flows of PSC for the year ended December 31, 1995 and for the five
     and one-half month period ended June 16, 1996 are included elsewhere in the
     Prospectus. The Company's accounts as of the date of the acquisition
     reflect the fair value of the assets acquired and liabilities assumed (see
     Note 4 - Acquisitions).

                                                                            F-7

2.   Significant Accounting Policies

     Principles of Consolidation
     The accompanying consolidated financial statements include the accounts of
     the Company and its subsidiaries. All significant intercompany accounts and
     transactions have been eliminated.

     Estimates and Assumptions
     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amounts of assets and liabilities and
     disclosure of contingent assets and liabilities at the date of the
     financial statements and the reported amounts of revenue and expenses
     during the reporting periods. Actual results could differ from those
     estimates.

     Interim Financial Information
     The consolidated financial statements of the Company for the six months
     ended June 30, 1998 are unaudited. All adjustments (consisting only of
     normal recurring adjustments) have been made, which, in the opinion of
     management, are necessary for a fair presentation. Results of operations
     for the six months ended June 30, 1998 are not necessarily indicative of
     the results that may be expected for the year ending December 31, 1998, or
     for any other future period.

     Foreign Currency Translation
     The functional currencies of the Company's foreign subsidiaries are the
     local currencies. Accordingly, assets and liabilities of foreign
     subsidiaries are translated to U.S. dollars at period-end exchange rates
     and revenues and expenses are translated using the average rates during the
     period. The effects of foreign currency translation adjustments have been
     accumulated and are included as a separate component of stockholders'
     equity (deficit). Foreign currency transaction gains and losses, arising
     from exchange rate fluctuations on transactions denominated in currencies
     other than the functional currencies, were immaterial for all periods
     presented.

     Revenue Recognition
     Internet and on-line service revenues encompass subscription and usage fees
     and are earned over the period services are provided. Other revenues,
     consisting principally of marketing services and transaction fees from the
     sale of merchandise, are recognized as services are provided or fees are
     earned. Unearned revenue consists primarily of monthly subscription fees
     billed in advance.

     Subscriber Acquisition Costs
     Direct response advertising costs which result in subscriber registrations
     without further effort required by the Company are capitalized and
     amortized over their estimated useful life subject to recoverability
     limitations. No such subscriber acquisition costs have been capitalized due
     to the uncertainty of recovery. General marketing costs, as well as all
     other costs related to the acquisition of subscribers, are expensed as
     incurred.

                                                                            F-8

     Advertising Costs
     Advertising costs are included in marketing expenses and are expensed as
     incurred.

     Cash and Cash Equivalents
     The Company considers all highly liquid investments with original
     maturities at date of purchase of three months or less to be cash
     equivalents. Cash and cash equivalents are stated at cost, which
     approximates fair value because of the short maturity of these instruments.

     Restricted Cash
     Restricted cash represents collateral for outstanding letters of credit.

     Property and Equipment
     Property and equipment is recorded at cost and depreciated using the
     straight-line method over the estimated useful lives of the assets.
     Expenditures for major renewals and betterments that extend the useful
     lives of property and equipment are capitalized. Expenditures for
     maintenance and repairs are charged to expense as incurred. When assets are
     sold or otherwise disposed of, the cost and related accumulated
     depreciation are relieved and any resulting gain or loss is recognized.

     Product Development Costs
     Software development costs are expensed as incurred until technological
     feasibility has been established. The Company determines technological
     feasibility upon the completion of a working model. Once technological
     feasibility has been established, such costs are capitalized until the
     software is available for general release to customers. Amortization is
     calculated on a product-by-product basis, using the greater of the
     straight-line basis over the estimated economic lives of the related
     products, two years, or the ratio of current gross revenue to total current
     and expected future gross revenue of the related products. The amortization
     and write-down of deferred software development costs is included in "Costs
     of Revenue."

     Research and Development
     Research and development costs are expensed as incurred.

     Investment in Joint Venture
     The Company had an investment in a foreign joint venture operating in China
     which was accounted for under the equity method of accounting, as the
     Company did not have a controlling interest. As of December 31, 1997, the
     Company's investment was written down to its net realizable value of zero
     (see Note 5 - Dispositions).

     The assets and revenues of the joint venture were immaterial for all
     periods presented.

                                                                            F-9

     Tradename
     The "Prodigy" tradename was recorded at fair value as of June 17, 1996,
     upon the acquisition of PSC. The tradename is amortized on a straight-line
     basis over 10 years.

     Long-Lived Assets
     The Company periodically evaluates the net realizable value of long-lived
     assets, including the Prodigy tradename and property and equipment, relying
     on a number of factors including operating results, business plans,
     economic projections and anticipated future cash flows. An impairment in
     the carrying value of an asset is recognized when the expected future
     operating cash flows derived from the asset are less than its carrying
     value. In addition, the Company's evaluation considers nonfinancial data
     such as market trends, product and development cycles, and changes in
     management's market emphasis.

     Income Taxes
     Deferred tax liabilities and assets are recognized based on temporary
     differences between the financial statement and tax bases of assets and
     liabilities using current statutory rates. A valuation allowance is applied
     against net deferred tax assets if, based on the weighted available
     evidence, it is more likely than not that some or all of the deferred tax
     assets will not be realized.

     Contingent Convertible Notes
     The contingent convertible notes issued in connection with the acquisition
     of PSC are classified in stockholders' Equity (deficit). In 1997, the
     Company exchanged the contingent convertible notes for contingent
     convertible notes and contingent warrants (see Note 9 - Contingent
     Convertible Notes and Warrants).

     Accounting for Stock-Based Compensation
     The Company adopted Statement of Financial Accounting Standards No. 123
     (SFAS No. 123), "Accounting for Stock-Based Compensation," in 1996. As
     permitted by SFAS No. 123, the Company has elected to continue to apply the
     intrinsic value methodology provisions of Accounting Principles Board
     Opinion No. 25, "Accounting for Stock Issued to Employees," for the grants
     or awards of equity instruments to employees. As required by SFAS No. 123,
     the Company has disclosed the pro forma effect on net loss of using a fair
     value approach to measure compensation for grants or awards of equity
     instruments in 1996 and 1997 (see Note 11 - Stockholders' Equity
     (Deficit)).

     Net Loss Per Share
     The Company computes basic and diluted earnings per share in accordance
     with Statement of Financial Accounting Standards No. 128 ("SFAS 128"),
     "Earnings per Share." SFAS 128 requires the Company to report both basic
     earnings per share, which is based on the weighted average number of common
     shares outstanding, and diluted earnings per share, which is based on the
     weighted average number of common shares outstanding and all dilutive
     potential common shares outstanding. As the Company incurred losses for all
     periods presented, there is no difference between basic and diluted
     earnings per share.

                                                                            F-10

     Concentrations of Credit Risk
     Financial instruments which potentially subject the Company to
     concentrations of credit risk consist principally of cash and trade
     receivables. Concentration of credit risk with respect to cash is limited
     as the Company invests its cash in deposits with several financial
     institutions. Concentration of credit risk with respect to trade
     receivables is limited as the outstanding total represents a large number
     of customers with individually small balances. The Company does not require
     collateral or other security against trade receivable balances; however, it
     does maintain reserves for potential credit losses and such losses have
     been within management's expectations.

     Reclassifications
     Certain amounts from the prior year have been reclassified to conform with
     the current year presentation.



3.   Restructuring and Other Special Costs

     Fiscal Year 1996 Restructurings and Other Special Costs
     The components of the Company's restructuring provision at December 31,
     1996 are detailed below:

            (A) Prodigy Services                                  $ 8,321
            (B) Cost reduction plan                                 3,147
                                                                  -------

                                                                  $11,468
                                                                  =======

     (A)  In connection with the acquisition of PSC as of June 17, 1996, the
          Company assumed non-recurring liabilities classified as "accrued
          Restructuring and Other Special Costs" of $10,738, of which $8,321
          remained outstanding as of December 31, 1996, and payable in 1997.
          These non-recurring liabilities related to restructuring plans which
          occurred prior to the acquisition date in connection with (i) a lease
          cancellation penalty for PSC's lease of its White Plains, NY
          facilities, of which $7,826 was outstanding as of December 31, 1996,
          and (ii) salary continuance and related liabilities resulting from job
          eliminations and early retirements of certain executives, of which
          $495 was outstanding as of December 31, 1996.

     (B)  In 1996, subsequent to the PSC acquisition, the Company approved
          another restructuring plan to reduce costs through additional job
          eliminations and a reduction in the use of leased office space, and as
          a result, recorded a restructuring charge of $3,147. Approximately 20
          employees were terminated in January 1997 and the related severance

                                                                            F-11

          cost of $659 was included in "Accrued Restructuring and Other Special
          Costs" at December 31, 1996. Beginning in November 1996, the Company
          vacated 29% of its leased space in White Plains, NY. The cost of the
          lease attributed to the idle leased facility amounted to $2,488 and
          was included in "Accrued Restructuring and Other Special Costs" as of
          December 31, 1996.

          During 1997, the Company paid the balance of the 1996 accrued
          restructuring and other special costs.

     Fiscal Year 1997 Restructurings and Other Special Costs
     In an effort to decrease cash outflows and more efficiently manage its
     business, the Company decided to restructure its operations and outsource
     its network and content production functions. The Company's provisions,
     expenditures and remaining balances to be paid are detailed below:

     (A)  In connection with the sale of its network (see Note 5 - Dispositions,
          sale of network), the Company incurred liabilities related primarily
          to early termination payments and other contractual obligations for
          certain non-cancelable network related agreements.

     (B)  The Company implemented a restructuring plan to reduce costs through
          job elimination, and as a result, recorded a charge of $2,900.
          Approximately 80 employees throughout the Company were terminated.

     (C)  The Company decided to discontinue the production of its own content,
          and as a result, recorded a charge of $585 to account for the employee
          termination costs and the costs to settle content related contractual
          obligations. Approximately 25 employees were terminated.

     (D)  The Company's Medford, Massachusetts location has been closed and a
          charge of $1,629 was recorded to account for the costs of employee
          terminations and lease cancellation. 

                                                                            F-12

          The terminated employees were involved with the Company's
          international operations and/or former headquarters management.
          Approximately 20 employees were terminated.


4.   Acquisitions

     Acquisition of Minority Interest in Subsidiary
     In January 1996, the Company purchased 90 shares of common stock of Comstar
     Cellular S.A. Cote d'Ivoire ("Comstar Cote d'Ivoire") from a minority
     shareholder and employee in exchange for $300 in cash and 350,000 shares of
     common stock of the Company with a value of $3 per share. As a result of
     this transaction, the Company's equity interest in Comstar Cote d'Ivoire
     increased from 91% to 100%.

     The acquisition was accounted for as a purchase and the excess of the
     purchase price over the fair value of the assets acquired and liabilities
     assumed, representing goodwill, amounted to $1,350 and was included with
     assets held for sale in connection with the sale of International Wireless,
     which included the cellular operations of Comstar Cote d'Ivoire.

     Investment in Global Enterprise Services, Inc. ("GES")
     During the period from January 1996 to March 1996, the Company acquired a
     48% voting interest in GES, represented by 4,800,000 shares of convertible
     preferred stock, for $9,000. The preferred stock has voting rights and is
     convertible into common stock. In 1996, the Company recorded a charge of
     $9,053 to reduce the carrying value of its investment in GES to an
     estimated net realizable value of zero.

     In January 1997, pursuant to a redemption agreement, the Company disposed
     of its 48% interest in GES for $250.

     Acquisition of Prodigy Services
     On June 17, 1996, the Company acquired all of the partnership interests of
     International Business Machines Corporation ("IBM") and Sears Roebuck and
     Co. ("Sears") in PSC. The Company acquired the assets and assumed the
     liabilities of PSC, with the exception of certain patents and all
     obligations and liabilities related to employee retirement and other
     postretirement benefit plans. The assets purchased and liabilities assumed,
     and related results of operations, are included in the consolidated
     financial statements of the Company from the date of acquisition. The
     aggregate purchase price of $78,116 consisted of a cash payment of $40,800,
     the issuance of Contingent Convertible Notes (see Note 9 - Contingent
     Convertible Notes and Warrants) valued at $30,500, and direct acquisition
     related expenses of $6,816.

     The acquisition was accounted for as a purchase. Accordingly, the purchase
     price was allocated to the identifiable assets and liabilities of PSC based
     on fair values. The fair value of intangible assets was determined using a
     risk adjusted discounted cash flows approach. 

                                                                            F-13

     Specifically, the Prodigy Internet technology acquired was evaluated
     through extensive interviews and analysis of data concerning the state of
     the technology and needed developments. The evaluation of the underlying
     technology acquired considered the inherent difficulties and uncertainties
     in completing the development, and thereby achieving technological
     feasibility, and the risks related to the viability and potential changes
     to target markets. Incomplete technology had no alternative future use.
     Therefore, the Company recognized a charge of $46,090 for the purchase of
     incomplete technology in 1996.

     In connection with the acquisition, the Company entered into a Funding
     Agreement (the "Funding Agreement"), as described in Note 8 - Notes
     Payable, with Carso Global Telecom and another stockholder of the Company
     (the "Stockholder"). The Funding Agreement was amended in October 1996 and
     March 1997.


5.   Dispositions

     Sale of International Wireless
     Effective January 1997, the Company sold all issued outstanding capital
     stock of IW to a company (the "Buyer") formed by a former executive and
     shareholder of the Company (the "Executive"). The assets of IW at the time
     of the sale consisted of cellular communications licenses and license
     applications in certain African countries, and the associated rights and
     assets used in the Company's cellular telephone activities. Africa Online,
     Inc., formerly a wholly-owned subsidiary of IW, had been transferred to
     another subsidiary of the Company (see Exit of International Operations,
     below). The Company also retained the joint venture investment in China
     previously held by IW (see Exit of International Operations, below). The
     selling price consisted of (i) the surrender of 5,571,429 shares of common
     stock of the Company, (ii) a Promissory Note (the "Note") in the amount of
     $21,500 due in full on July 27, 1997, including $1,500 in reimbursement of
     capital expenditures made by the Company for the benefit of IW, secured by
     a pledge of 67% of the shares of IW purchased from the Company, and bearing
     interest at 9% until April 27, 1997 and 12% thereafter, and (iii) the
     termination of the Executive's fully vested options to purchase 500,000
     shares of common stock for $0.25 per share and 500,000 shares of common
     stock for $2.00 per share.

     In October 1997, the Company and the Buyer modified the Note as follows:
     (i) the due date was extended to January 31, 1999, (ii) the Note is
     unsecured, (iii) the interest rate was reduced to 8%, (iv) the Note is
     subject to mandatory repayment out of the net proceeds from an acquisition
     of IW, (v) the Note is also subject to mandatory repayment to the extent of
     10% of the first $5,000 in net financing proceeds received by IW (with
     certain exceptions), 20% of the next $5,000 in proceeds and 40% of all
     proceeds in excess of $10,000, and (vi) the Company is allowed to convert
     the Note upon maturity into equity securities of IW at a 20% discount from
     the price at which IW has sold equity securities to investors. The Buyer
     also surrendered an additional 2,294,321 shares of common stock of the
     Company in exchange for a reduction in IW's unpaid obligations at October
     31, 1997 to $16,148.


                                                                            F-14
<PAGE>
 
PRODIGY COMMUNICATIONS CORPORATION

Notes to Consolidated Financial Statements, Continued
(in thousands, except share and per share amounts)               
     
     As a result of the restructuring of the Note and the revaluation of the
     Company's stock from $3 to $1 per share, a loss on the sale of IW of $848
     was recorded in 1997. The Note has been valued at zero. Any future cash
     collected against the Note will be accounted for as a gain in "Other
     Income." As of December 31, 1996, the Company reclassified certain assets
     of $11,263 as "Assets Held for Sale" in connection with the sale of IW.

     Sale of Network
     Prodigy owned and operated its own network in the United States until July
     1, 1997. Effective July 1, 1997, the Company sold to Splitrock Services,
     Inc. ("Splitrock") certain of its network assets. Splitrock agreed to: (i)
     assume all equipment leases, maintenance and license liabilities related to
     network assets, and (ii) enter into a Full Service Agreement whereby
     Splitrock will provide certain network services to the Company including
     commitments to meet certain capacity and performance requirements. Carso
     Global Telecom owns a minority interest in Splitrock.

     The Company also entered into a Sublease Agreement pursuant to which
     Splitrock subleases a portion of the Company's leased space in Yorktown
     Heights, New York, effective July 1, 1997 through February 28, 2001.

     Pursuant to the Full Service Agreement, effective July 1, 1997, Splitrock
     provides to the Company network services consisting primarily of end-to-end
     connection services from subscriber dial-up lines to the Company's data
     center. Splitrock charges Prodigy at a fixed rate per subscriber, subject
     to a monthly maximum usage limit, after which an incremental hourly rate is
     charged, and certain minimum charges (see Note 12 - Commitments and
     Contingencies).

     Under a transition services agreement, Prodigy agreed to pay for certain of
     Splitrock's operating expenses and to provide temporary network-related
     services to Splitrock, including accounting, human resources and purchasing
     functions. Splitrock agreed to reimburse Prodigy for expenses incurred and
     the cost of providing these support services (excluding termination
     penalties under existing network contracts). The total of the reimbursed
     expenses and service costs in 1997 was $27,532. The reimbursed amounts have
     been offset against the corresponding expenses and costs in the statements
     of operations. The transition services agreement terminated on December 31,
     1997, although the Company continued to provide certain incidental services
     and make payments on behalf of Splitrock through June 30, 1998. The net
     amount due from Splitrock under the Full Service Agreement and the
     transition services agreement as of December 31, 1997 was $674. This amount
     is recorded under the heading "Other Receivable" on the balance sheet.
     Splitrock has notified Prodigy of the PLS leases, which it wishes to
     assume, and Prodigy remains liable for all PLS leases not assumed by
     Splitrock. Prodigy also remains liable for all obligations and termination
     penalties under its existing agreements with IBM Global Network Services
     and other third-party providers of Points of Presence ("POPs"). The costs
     associated with the PLS leases retained by the Company and the termination
     penalties have been accrued as part of network termination costs as of
     December 31, 1997 (see Note 3 - Restructuring and Other Special Costs). 

                                                                            F-15

(in thousands, except share and per share amounts)               

     Upon termination of the transition services agreement, a Full Services
     Agreement became effective, and Splitrock hired all Prodigy employees
     engaged in Prodigy's network operations. Splitrock is required to provide
     dial-up network access in all locations in which Prodigy provided dial-up
     services as of July 1, 1997. Commencing December 31, 1999, Splitrock will
     not be required to support the proprietary standards on which the Prodigy
     Classic service operates.

     Under the Full Service Agreement, Splitrock is required to meet specified
     service level objectives. Splitrock's failure to meet the service level
     objectives results in financial penalties. If Splitrock fails to meet the
     service level objectives for an extended period of time, Prodigy may
     terminate the Full Service Agreement. In addition, if there is a
     system-wide failure, or Splitrock breaches specified financial covenants,
     Prodigy has the right to terminate the Full Service Agreement or assume
     responsibility for operating the network at Splitrock's expense.

     As a result of the sale of the network effective July 1, 1997, the Company
     sold property and equipment with a net book value of approximately $9,400
     and did not record any gain or loss upon the sale of these assets. The net
     book value of the equipment was removed from property and equipment on the
     balance sheet and classified in "Other Intangible Assets, Net" and is being
     amortized over the four year term of the Splitrock contract on a
     straight-line basis.

     Exit of International Operations
     In December 1997, management decided to exit its international operations
     in order to focus on its domestic internet service business. During 1996
     and 1997, the Company's incurred losses of $539 and $12,101, respectively,
     in relation to its joint venture operation in China.

     The assets of Africa Online, Inc., a wholly-owned subsidiary, are carried
     as assets held for sale at their estimated fair value of $1,650, as of
     December 31, 1997. Africa Online, Inc. was originally part of IW. The
     Company recorded a charge of $2,400 in 1997 to reduce the carrying value of
     Africa Online, Inc. long lived assets to their estimated net realizable
     value.

                                                                            F-16

8.   Notes Payable

     Notes payable consisted of the following at December 31:

                                                   =======          =======

     In June 1996, the Company entered into a loan agreement with Banco Inbursa
     ("Inbursa"), an affiliate of Carso Global Telecom, whereby Inbursa agreed
     to provide a credit facility to the Company of up to $50,000 with an
     original maturity date in June 1997, at an interest rate of prime plus
     1/2%. Borrowings under this credit facility are collateralized by a pledge
     of 17,000,000 shares of the Company's common stock of which 7,000,000
     shares were pledged by Carso Global Telecom and 10,000,000 shares are
     pledged by the stockholder. As a result of an extension of the credit
     facility from Inbursa, the maturity date for outstanding borrowings of
     $10,000 was extended from June 17, 1997 to December 31, 1999. The
     Stockholder had agreed to continue to make available for pledge, until June
     13, 1998, 10,000,000 shares of common stock to secure a new line of credit
     from a U.S. bank or other debt financing to replace or extend the line of
     credit from Inbursa. Subsequent to December 31, 1997, all loans were repaid
     and stock pledges terminated.

     Pursuant to an amendment to the Company's original Funding Agreement
     effective March 18, 1997, the Company exercised a Put option to issue
     common stock to the Stockholder for $15,000 and to Carso Global Telecom for
     $65,000, of which $40,000 was used to partially repay the $50,000 loan from
     Inbursa. The remaining Put of $45,000 was allocated $39,000 to Carso Global
     Telecom and $6,000 to the Stockholder. The aggregate proceeds of $80,000
     from the exercise of the Put, as well as proceeds from subsequent Put
     exercises of $9,000, were raised through the issuance of 29,666,667 shares
     of common stock at $3 per share. All amounts available under the Put have
     been exercised.

     In October 1997, Carso Global Telecom and the Stockholder arranged interim
     financing for the Company. Carso Global Telecom agreed to (i) establish a
     $4,000 letter of credit required as part of the revised Contingent
     Convertible Notes and Warrants (see Note 9 - Contingent Convertible Notes
     and Warrants), (ii) arrange for Inbursa to lend $13,750 to the Company, of
     which $3,750 is secured by the Stockholder's pledge of 7,500,000 shares of
     common stock, and (iii) indicate its intention to purchase, under a rights
     offering, its maximum allocation of 49,543,822 shares of common stock. In
     payment for its 49,543,822 shares, Carso Global Telecom will (i) be
     credited with $4,000 for the issuance of the $4,000 letter of credit, (ii)
     pay $13,750 directly to Inbursa on the Company's behalf,

                                                                            F-18

(in thousands, except share and per share amounts)


     and (iii) pay to the Company the remainder of the purchase price of $31,794
     less any other funds advanced to the Company prior to the closing of the
     rights offering. Subsequent to the issuance of the $4,000 letter of credit,
     on a quarterly basis, Carso Global Telecom will contribute $333, less any
     draws on the letter of credit, until the $4,000 has been paid to the
     Company. The Stockholder agreed to (i) lend the Company up to $2,250
     without interest, (ii) pledge 7,500,000 shares of common stock to secure
     advances of $3,750 from Inbursa until the earlier of the closing of the
     rights offering (see Note 11 - Stockholders' Equity (Deficit)) or December
     15, 1997, and (iii) convert its advances to the Company into common stock
     upon the closing of the rights offering. As of December 31, 1997, interim
     financing of $27,100 had been re-paid in connection with the rights
     offering.

     In March 1996, the Company borrowed $2,000 from a network company (the
     "Corporate Lender") pursuant to an 8-1/4% convertible note. Principal and
     interest were due on March 31, 1997. The note has not been formally
     extended. The Corporate Lender had the right within 30 days after the
     completion of a private placement and prior to March 31, 1997 to convert
     the principal and interest into common stock at the price per share at
     which the Company's common stock is issued in the private placement.

     Additional Financing
     In February 1998, the Company entered into an additional loan agreement
     with Inbursa in the amount of $16,400, payable December 31, 1999 at an
     interest rate of 9%. In July 1998, a further $5,700 was borrowed from
     Inbursa, payable December 31, 1999 at an interest rate of 9%. Also in July
     1998, the Company borrowed $30,000 from Bank of America National Trust and
     Savings Association ("Bank of America"), payable on August 14, 1998 at an
     interest rate of 6.5%. This loan was collateralized by the funds of Carso
     Global Telecom held with Bank of America. The proceeds from this loan were
     used to pay down the Inbursa notes payable. Subsequent to December 31,
     1997, the Bank of America loan was repaid in full.

     In August 1998, the Company secured a $35,600 line of credit commitment
     from Carso Global Telecom. This credit facility expires on December 31,
     1999 and bears interest at the LIBOR rate plus between one and five
     percentage points (as negotiated on a case-by-case basis).

9.   Contingent Convertible Notes and Warrants

     The Contingent Convertible Notes ("Contingent Notes") issued in connection
     with the acquisition of PSC (see Note 4 - Acquisitions), would have accrued
     interest at a rate of 8% annually commencing on December 17, 1997.

                                                                            F-19
<PAGE>
 
PRODIGY COMMUNICATIONS CORPORATION

Notes to Consolidated Financial Statements, Continued
(in thousands, except share and per share amounts)


     The Contingent Notes were convertible into shares constituting 15% of the
     Company's then outstanding common stock on a fully diluted basis (or 15% of
     the consideration received in the event that the Company is acquired),
     limited to a value equal to $200,000 plus contingent interest, upon the
     earlier of (i) an initial public offering by the Company resulting in gross
     proceeds of at least $25,000, (ii) an acquisition of the Company, (iii)
     following an initial public offering with gross proceeds of less than
     $25,000, the first date on which the Company's market value exceeds
     $200,000, or (iv) June 17, 2006. Principal and contingent interest were not
     required to be paid in cash, except in the event that the Company is
     acquired for cash. In lieu of conversion upon an initial public offering or
     upon maturity, the Company had the option, but not the obligation, to
     redeem the Contingent Notes for $200,000 plus accrued contingent interest
     in cash.

     In November 1997, IBM and Sears exchanged the Contingent Notes for (i)
     contingent notes in the face amount of $200,000 and (ii) contingent
     warrants to acquire up to 15% of the Company. Subject to a maximum of
     $200,000, the contingent notes are convertible into 15% of the value of the
     Company's common stock in excess of $250,000. The warrants allow IBM and
     Sears to purchase up to 15% of the Company at 130% of the fair market value
     at the date of conversion of the contingent notes. The warrants are
     exercisable at any time prior to the third anniversary of the conversion of
     the contingent notes. As a condition to these arrangements, Carso Global
     Telecom prepaid (as an advance to the Company) the balance due on the White
     Plains lease of $5,831. Carso Global Telecom also established a $4,000
     letter of credit, declining quarterly over three years, to secure other
     payment obligations of the Company under contracts for which IBM and Sears
     retained liability. After conversion of the contingent notes or exercise of
     the contingent warrants, IBM and Sears have agreed to vote their shares of
     common stock in accordance with the voting recommendations of the Company's
     Board of Directors.

                                                                            F-20

10.  Income Taxes

     The Company had no income tax expense for the years ended December 31, 1996
     and 1997 as a result of net losses. As of December 31, 1996 and 1997, the
     Company's deferred tax assets (liabilities) were as follows:

                                                       1996            1997

     Net deferred tax asset                          $     -        $     -
                                                     ========       ========

     At December 31, 1997, the Company had net operating loss carryforwards for
     federal income tax purposes of approximately $115,000 which may be used to
     offset future taxable income, beginning to expire in 2009. The utilization
     of the federal income tax loss carryforwards is subject to limitation as a
     result of a change of ownership. The Company also has operating loss
     carryforwards in various foreign subsidiaries of approximately $22,100
     which began to expire in 1998 and may be used to offset future taxable
     income in those countries.

     Management of the Company has evaluated the positive and negative evidence
     bearing upon the realizability of its deferred tax assets, which are
     comprised principally of net operating loss carryforwards. Under the
     applicable accounting standards, management has considered the Company's
     history of losses and concluded that it is more likely than not that the
     Company will not realize these favorable tax attributes. Accordingly, the
     deferred tax assets have been fully reserved. Management revaluates the
     positive and negative evidence periodically.


11.  Stockholders' Equity (Deficit)

     Authorized Shares of Common Stock 
     In 1996, the Board of Directors and the stockholders approved an increase
     in the authorized shares of common stock to 140,000,000 shares.

     In 1997, the Board of Directors and the stockholders approved a further
     increase in the authorized shares of common stock to 280,000,000 shares.

                                                                            F-21

     Private Placement
     In October 1996, the Company offered up to 8,000,000 shares of its common
     stock in a private placement, resulting in net proceeds to the Company from
     investors (other than Carso Global Telecom and the Stockholder) of
     approximately $1,843. In February 1997, the Company increased the size of
     the offering from 8,000,000 shares to 16,000,000 shares of common stock and
     reduced the offering price to $3.00 per share from $7.00 per share. As a
     result of the reduction in the offering price, the Company offered to each
     investor the choice of either (i) receiving additional shares to reduce
     their average purchase price to $3.00 or (ii) rescinding their
     subscriptions and receiving refunds without interest upon the closing. The
     Company received aggregate gross proceeds of $88,843 and issued 29,614,412
     shares of common stock.

     In November 1997, the Company made a Rights Offering whereby each eligible
     stockholder was entitled to purchase at a price of $1.00 per share, one
     share of the Company's common stock for each share held. The Company issued
     50,561,915 additional shares and received $46,554 in cash and a $4,000 note
     receivable from Carso Global Telecom for the issuance of the IBM/Sears
     letter of credit (see Note 9 - Contingent Convertible Notes and Warrants).
     On a quarterly basis, Carso Global Telecom will contribute $333 less any
     draws on the letter of credit until the $4,000 has been paid to the
     Company.

     Additional Financing
     In August 1998, the Company sold 24,500,000 shares of common stock at a
     price of $2.00 per share to Telefonos de Mexico, S.A. de C.V. ("Telmex"),
     an affiliate of Carso Global Telecom, resulting in proceeds of $49,000 to
     the Company. At the same time Carso Global Telecom purchased an additional
     5,500,000 shares of common stock at a price of $2.00 per share, resulting
     in proceeds of $11,000 to the Company. These proceeds were used to repay
     the $30,000 note payable to Bank of America and a remaining $2,100 in notes
     payable to Inbursa, with the balance to be used for general corporate
     purposes.

     Stock Option Plan
     In 1996, the Board of Directors and the stockholders approved a Stock
     Option Plan (the "Plan"). Under the Plan, options to purchase up to
     9,500,000 shares of common stock may be granted to employees, directors,
     consultants and advisors of the Company. Options granted may be either
     "incentive stock options" or "nonqualified options." All options issued
     under the Plan are exercisable over periods determined by the Board of
     Directors, not to exceed 10 years from the date of grant. Options generally
     vest over periods ranging from 3-5 years. In September 1997, the Board of
     Directors and the stockholders approved an increase of 3,000,000 to the
     number of shares of common stock available for future grants. These options
     have the same terms and conditions as the shares initially authorized under
     the 1996 Plan.

     for the years ended December 31, 1996 and 1997 would have been
     approximately $116,512 and $133,395, respectively. The effects of this pro
     forma disclosure are not indicative of future amounts. Additional awards
     are anticipated in future years. The weighted average fair value of the
     options granted during the years ended December 31, 1996 and 1997 was
     estimated at $1.69 and $0.28 per share, respectively, on the date of grant
     using the Black-Scholes option-pricing model with the following
     assumptions: no dividend yield, volatility of 55% for 1996 and 1997, risk-
     free rate of 6.16% for 1996 and 5.99% for 1997, and an expected option life
     of 4.6 years from date of vesting for 1996 and 1997.

     In determining the fair value of the common stock at the date of grant
     under the Plan, the Board considered a broad range of factors including the
     illiquid nature of an investment in the Company's common stock,
     transactions in the Company's common stock, the Company's historical
     financial performance relative to that of comparable companies and its
     future prospects.

     Repricing of Stock Options
     In June 1997, the Board approved a repricing plan to reprice employee stock
     options under the Plan to restore the long-term employee retention and
     performance incentives of the stock options outstanding. In accordance with
     the repricing plan, all stock options held by current, active full-time
     employees, with exercise prices above $3.00 per share, were canceled and
     replaced by the same number of options exercisable at $3.00 per share, the
     fair value of the Company's common stock as determined by the Board on the
     date of the repricing.

     In May 1998, the Board approved a repricing plan to reprice employee stock
     options under the Plan to restore the long-term employee retention and
     performance incentives of the stock options outstanding. In accordance with
     the repricing plan, all stock options held by current, active full-time
     employees, with exercise prices above $1.00 per share, were canceled and
     replaced by the same number of options exercisable at $1.00 per share, the
     fair value of the Company's common stock as determined by the Board on the
     date of the repricing.

     The exercise and vesting periods of the outstanding options were not
     altered by the repricings.

     In making the determinations of the fair value of the Company's common
     stock, the Board considered a broad range of factors including the illiquid
     nature of an investment in the Company's common stock, transactions of the
     Company's common stock, the Company's historical financial performance
     relative to that of comparable companies and its future prospects.

                                                                            F-24

     Stock Warrants
     In October 1996, the Stockholder exercised his warrant to purchase 270,000
     shares of common stock at a price of $3.00 per share, less a discount
     resulting in proceeds of $792 to the Company. The discount was approved by
     the Company's Board of Directors and was agreed upon to reflect the fact
     that the Stockholder exercised the warrant prior to its expiration date of
     December 31, 1996. In December 1996, Carso Global Telecom exercised its
     warrant to purchase 2,700,000 shares of common stock at a price of $3.00
     per share, resulting in proceeds of $8,100 to the Company. These warrants
     were granted in consideration of the commitments described in the Funding
     Agreement (see Note 4 - Acquisition of Prodigy Services).

     The warrant to purchase 1,000,000 shares issued to Carso Global Telecom in
     1996 was canceled in March 1997, at which time the Company granted Carso
     Global Telecom and the Stockholder warrants to purchase 13,000,000 shares
     and 2,000,000 shares, respectively, of common stock for $3 per share,
     exercisable prior to or on November 12, 1997. In October 1997, in
     consideration of the interim financing (see Note 8 - Notes Payable), the
     exercise price was reduced from $3.00 per share to $1.00 per share.

     At December 31, 1997, the Company had warrants outstanding with various
     shareholders, including Carso Global Telecom, to purchase 15,437,389 shares
     of the Company's common stock at an average price of $1.05 per share. Of
     the outstanding warrants, 15,000,000 may be exercised at any time until the
     earlier of May 12, 1998, or an initial public offering. Of the remainder,
     88,056 warrants expire between May and December 2001, and 349,333 expire
     between May and August 2005. In April 1998, 13,000,000 warrants were
     exercised at $1.00 per share. In May 1998, 2,000,000 warrants were
     exercised at $1.00 per share.

12.  Commitments and Contingencies

     Commitments
     At December 31, 1997, the Company's minimum rental commitments under
     noncancelable operating leases with initial or remaining terms of more than
     one year were as follows:

     The Company's rent expense in the years ended December 31, 1996 and 1997
     was approximately $5,800 and $9,192, respectively.

     In December 1993, PSC entered into a noncancelable agreement with a
     telephone company to provide certain services at the Company's White Plans,
     NY and Yorktown, NY facilities. The agreement has a term ("service period")
     of ten years. The agreement calls for line charges totaling $510 per year.
     The Company has the right to terminate the agreement for certain services
     at any time at a cost of 80% of the line charges over the remaining
     services period.

     The Company is party to a contract for a subscription management system
     through June 2001. This contract requires minimum annual payment of
     processing fees of $900. For the years ended 1996 and 1997, the Company
     paid $5,055 and $3,628, respectively.

     The Company is party to a number of other agreements with information
     providers which require payment of fees based upon the number of
     subscribers or subscriber usage of providers' data.

     Under the Company's four-year agreement with Splitrock, the Company is
     obligated to minimum annual payments of $39,000 in 1998, $45,000 in 1999,
     $51,000 in 2000 and $27,000 in 2001 and maximum monthly charges based on
     the number of the Company's subscribers for the month. The agreement
     provides for early termination charges of $7,000 in the first year,
     declining thereafter of an annual basis. The agreement is automatically
     renewed for successive 12-month periods unless terminated by either party
     upon 12-months notice.

     In September 1997, the Company entered into a 22-month agreement with a
     vendor to provide network licensing and technical support. This agreement
     requires annual payments of $714 and $429, in 1998 and 1999, respectively.
     Upon 30-day prior written notice, the Company can terminate the agreement
     without penalty. The agreement can be extended for an additional 12 months.

     As of December 31, 1997, the Company was contractually obligated to pay IBM
     a network termination penalty of $7,500 as part of the sale of the
     Company's network. The Company is currently negotiating with IBM to settle
     this liability through a defined purchasing plan, whereby the Company will
     be obliged to purchase services from IBM through December 31, 2000, up to
     $7,500 in value, with any shortfall being paid as a penalty. The Company
     has accrued $2,000 as of December 31, 1997, representing management's best
     estimate of the anticipated penalty to IBM. This amount is included in the
     Company's accrued network termination cost (see Note 3 - Restructuring and
     Other Special Costs).

     Contingencies
     In June 1998, Lycos, Inc. ("Lycos") filed a complaint and motion for
     preliminary injunction in the Superior Court of Middlesex Country,
     Massachusetts against the Company. The lawsuit alleges, among other things,
     that the Company breached a license agreement with Lycos by 

                                                                            F-26

     entering into a portal outsourcing agreement with Excite in January 1998
     and by terminating the license agreement between Lycos and the Company. The
     lawsuit seeks specific performance of the license agreement between Lycos
     and the Company, a preliminary and permanent injunction enjoining the
     Company from terminating the license agreement between Lycos and the
     Company and from performing under its agreement with Excite, money damages
     and attorneys' fees. A hearing on Lycos' motion for preliminary injunction
     has been adjourned because the parties are in negotiations to settle the
     lawsuit. However, there can be no assurance the lawsuit will be settled. If
     the lawsuit is not settled, the Company intends to defend it vigorously. It
     is not currently possible to estimate the effect of an unfavorable outcome
     to this lawsuit; however, it is possible that such an outcome could have a
     material adverse impact on the Company's operations.


13.  Defined Contribution Plan

     On June 17, 1996, as part of the Company's acquisition of PSC (see Note 4 -
     Acquisitions), the Company took on responsibility for the administration
     and sponsorship of the Prodigy Services Corporation Capital Accumulation
     Plan (the "Plan").

     The Plan is a defined contribution plan covering all employees of the
     Company. Employees can participate in the Plan from their first day of
     employment.

     Each year, active participants may contribute up to 12 percent of their
     pre-tax base salaries, up to the maximum amount allowed by the Plan. The
     Company contributes a matching contribution equal to 100 percent of an
     employee's pre-tax contributions, limited to a maximum of 3 percent of a
     participant's compensation. The Plan also has an after-tax savings feature
     that permits employees to contribute from 1 percent to 10 percent of their
     base salaries subject to Internal Revenue Code limitations.

     The Company's contributions were $600 and $596 in 1996 and 1997,
     respectively.

                                                                            F-27

1.   Organization and Basis of Presentation

     Prodigy Services Company (the "Partnership") is a joint venture of
     International Business Machines Corporation ("IBM") and Sears, Roebuck &
     Co. ("Sears"). The Partnership was formed to develop and market PRODIGY(SM)
     (the "PRODIGY Service" or the "Service"), the national network that
     provides on-line services to households with personal computers.

     The Partnership was organized on February 13, 1984 as a New York State
     general partnership.

     On June 16, 1996, the Partners sold the PRODIGY Service, and the related
     assets and liabilities, of the Partnership to Prodigy, Inc., with the
     exception of certain patents and all obligations and liabilities related to
     employee retirement and postretirement benefit plans, for an aggregate
     purchase price of $78,116. These consolidated financial statements present
     the results of operations for the year ended December 31, 1995 and for the
     five and one-half month period from January 1, 1996 through June 16, 1996,
     and have been prepared using the Partnership's historical basis in the
     results of operations.


2.   Significant Accounting Policies

     Principles of Consolidation and Estimates
     The consolidated financial statements include the accounts of the
     Partnership and its majority-owned subsidiary, SonicNet, Inc. All
     significant intercompany transactions have been eliminated on
     consolidation. The preparation of financial statements in conformity with
     generally accepted accounting principles requires management to make
     estimates and assumptions that affect the reported amounts of revenues and
     expenses during the reporting periods. Actual results could differ from
     those estimates.

     Cash and Cash Equivalents
     Cash and cash equivalents are highly liquid investments with a maturity of
     three months or less when purchased and consist of deposits with banks and
     financial institutions which are unrestricted as to withdrawal or use.

                                                                            F-32

     Revenue Recognition
     On-line service revenues encompass subscription and usage fees. Term
     subscription fees are recognized on a pro-rata basis over the life of the
     related subscriptions. Other revenues consist principally of marketing
     services and transaction fees generated from goods and services purchased
     through the service. Revenues are recorded when services are rendered or
     products are delivered.

     Income Taxes
     The Partnership is not a taxable entity; accordingly, no provision for
     income taxes has been made in the financial statements. The Partners'
     respective shares of partnership losses are reportable on the individual
     Partner's corporate income tax returns.

     Property and Equipment
     Property and equipment is stated at cost. Depreciation and amortization is
     computed using the straight-line method over the estimated useful life of
     the asset or the lesser of the remaining lease term or the life of the
     improvement. Estimated service lives of these assets range principally from
     three to seven years.

     Repair and maintenance charges are expensed as incurred. When assets are
     sold, retired or otherwise disposed of, the applicable costs and
     accumulated depreciation and amortization are removed from the accounts and
     the resulting gain or loss is included in the consolidated statement of
     operations.

     Deferred Subscriber Acquisition Costs
     Certain subscriber acquisition costs are deferred and charged to operations
     using the straight-line method beginning the month after such costs are
     incurred. These costs are amortized over a fifteen to eighteen month
     period. These costs relate directly to subscriber solicitations and
     principally include printing, production and shipping of start-up kits.
     Costs incurred other than those targeted at specific identifiable prospects
     for the Partnership's services are expensed as incurred.

     Product Development
     The Partnership capitalizes the cost of developing computer software used
     in the sale of its services. The capitalization of these costs begins when
     technological feasibility has been established and ends when the product is
     available for general release to customers. Costs incurred prior to
     technological feasibility are expensed as incurred. Amortization expense is
     computed on a product-by-product basis using the straight-line method,
     primarily over a twenty-four month period beginning the month after the
     date of product release.

                                                                            F-33

     Concentrations of Credit Risk
     Financial instruments which potentially subject the Partnership to
     concentrations of credit risk consist principally of cash and trade
     receivables. Concentration of credit risk with respect to cash is limited
     as the Partnership invests its cash in deposits with several financial
     institutions. Concentration of credit risk with respect to trade
     receivables is limited as the outstanding total represents a large number
     of customers with individually small balances. The Partnership does not
     require collateral or other security against trade receivable balances;
     however, it does maintain reserves for potential credit losses and such
     losses have been within management's expectations.



3.   Investments

     In December 1995, the Partnership purchased a 53 percent ownership interest
     in SonicNet, Inc., a company formed to provide an interactive service of
     alternative rock music made available through a Prodigy web site on the
     Internet and through other interactive media. The investment consists of
     voting securities issued in exchange for the Partnership's commitment to
     provide funding of approximately $2,100 for SonicNet, Inc. in scheduled
     monthly payments through February 1997. The results of operations from the
     date of acquisition are included in the Partnership's net losses and are
     not material.

                                                                            F-34

     Capital Accumulation Plan
     The Partnership has a voluntary capital accumulation plan for all full-time
     employees. The plan is a defined contribution plan and is subject to the
     provisions of ERISA. Under the provisions of the plan, the Partnership
     matches the first 3% of base salary employee-deferred pre-tax
     contributions. The Partnership contributed approximately $1,100 and $600 to

7.   Other Postretirement Benefits

     The Partnership sponsors a defined benefit postretirement medical and life
     insurance plan for all full-time employees. The plan is unfunded.

     In 1995, the Partnership adopted Statement of Financial Accounting
     Standards No. 106 ("SFAS 106"), "Employers' Accounting for Postretirement
     Benefits Other than Pensions." The standard requires recognition of the
     estimated future cost of providing health and other postretirement benefits
     on the accruals basis.

     The Partnership recorded a net periodic postretirement benefit cost of $400
     in the five and one-half month period ended June 16, 1996.


8.   Restructuring and Other Special Costs

     In April 1996, the Company approved a restructuring plan to reduce costs
     through job eliminations and a reduction in the use of leased office space,
     and as a result recorded a restructuring charge of $14,561. This charge
     consisted of severance costs of $5,300 in connection with the planned
     termination of 20 employees, a lease termination penalty of $7,826, a
     write-down of $5,593 related to leasehold improvements, less the write-off
     of deferred rent concessions of $4,158.

INTERNATIONAL WIRELESS INCORPORATED AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1.   NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Nature of Business - International Wireless Incorporated (the "Company")
     was incorporated on May 23, 1994, as a Delaware corporation to develop and
     operate cellular telephone systems together with voice mail, paging and
     other enhanced services, including Internet access and on-line services, in
     developing countries throughout the world. In January 1996, through its
     investment in Global Enterprise Services, Inc., the Company expanded its
     Internet-related activities to the United States. In May 1996, the Company
     entered into an agreement to acquire Prodigy Services Company ("Prodigy"),
     resulting in a substantial change in the nature of the Company's
     activities. As a result of the Prodigy acquisition, the Company has become
     a major provider of on-line and Internet services while continuing to
     pursue the development of its cellular and other on-line activities in
     developing countries.

     Principles of Consolidation - The accompanying consolidated financial
     statements include the accounts of the Company and its majority-owned
     subsidiaries. All significant intercompany transactions and balances have
     been eliminated.

     Pro Forma Stockholders' Equity (Unaudited) - Pro forma stockholders' equity
     reflects the following transactions in 1996 as if they had occurred on
     December 31, 1995: the sale of the first 4,000,000 of 7,000,000 shares of
     common stock to a subsidiary of Grupo Carso, S.A. de C.V. ("Carso"), at $3
     per share pursuant to a stock subscription agreement (see Note 8 - Stock
     Subscription); the receipt of additional advances of $2,900,000 from a
     stockholder (the "Stockholder") and conversion of the additional advances
     and the outstanding advances at December 31, 1995 of $1,600,000 into
     1,500,000 shares of common stock at $3 per share (see Note 8 - Stockholder
     Advances); and, the sale in a private placement of 1,430,702 shares of
     common stock resulting in net proceeds to the Company of $4,239,707 (see
     Note 8 - Private Placement).

     Use of Estimates - The preparation of financial statements in conformity
     with generally accepted accounting principles necessarily requires
     management to make estimates and assumptions that affect the reported
     amounts of assets and liabilities and the disclosure of contingent assets
     and liabilities at the date of the financial statements and the reported
     amounts of revenues and expenses during the reporting period. Actual
     results could differ from those estimates.

     Revenues - Cellular service revenue is recognized as services are provided.
     Customer deposits represent receipts for cellular service subscriptions
     received by the Company's subsidiary in Cote d'lvoire.

     Cash Flow Information - Cash equivalents include highly liquid securities
     purchased with remaining maturities of less than three months. No cash was
     paid for income taxes or interest in 1994 and 1995.

     Property, Plant and Equipment - Property and equipment are recorded at
     cost. Depreciation is computed using the straight-line method over the
     estimated useful lives of the related assets, ranging from 3 to 8 years for
     automobiles and equipment and 40 years for buildings.

                                                                            F-43

1.   NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 
     (CONTINUED)

     Licenses - Licenses consist of cellular telephone licenses in certain
     African countries. The costs of obtaining the licenses have been deferred
     and are being amortized over the lesser of the period of the license or its
     estimated useful life. Amortization expense for the period ended December
     31, 1994 and for the year ended December 31, 1995 amounted to $3,960 and
     $9,074, respectively.

     Goodwill - Goodwill represents the excess of the purchase price over the
     fair value of net assets acquired and is being amortized over 10 years.
     Goodwill is periodically reviewed for impairment by comparison to future
     expected cash flows to be generated by the underlying operations.

     Foreign Currency Translation - The functional currencies of the Company's
     foreign subsidiaries are the local currency. Accordingly, assets and
     liabilities of foreign subsidiaries are translated to U.S. dollars at
     period-end exchange rates and revenues and expenses are translated using
     the average rates during the period. The effects of foreign currency
     translation adjustments have been accumulated and are included as a
     separate component of stockholders' equity.

     Income Taxes - Deferred tax assets and liabilities are provided to
     recognize differences in the book and tax bases of assets and liabilities.

     Financial Instruments - The carrying values of cash and equivalents,
     receivables and accounts and other payables approximate fair value due to
     the short-term nature of these instruments. Management believes that the
     amount due to stockholder approximates fair value because the terms were
     negotiated in the latter part of 1995.

     Impairment of Long-Lived Assets - The Company will be required to adopt
     Statement of Financial Accounting Standards ("SFAS") No. 121, "Accounting
     for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be
     Disposed Of," in 1996. The adoption of this statement is not expected to
     have a material effect on the Company's consolidated financial statements.

     Accounting for Stock-Based Compensation - The Company will be required to
     adopt SFAS No. 123, "Accounting for Stock-Based Compensation," in 1996. As
     permitted by SFAS No. 123, the Company will elect to continue to apply the
     intrinsic value methodology provisions of Accounting Principles Board
     Opinion No. 25 for grants or awards of equity instruments to employees.
     Also, as required by SFAS No. 123, the Company will use a fair value
     methodology to measure the compensation element of grants or awards of
     equity instruments to nonemployees and will disclose in its annual
     consolidated financial statements, beginning in 1996, the pro forma effect
     on net income of using a fair value approach to measure compensation for
     all grants or awards of equity instruments.

                                                                            F-44

2.   ACQUISITIONS

     Comstar Cellular Network, Inc. ("Comstar") - In August 1994, the Company
     issued 21,336,850 shares of common stock in exchange for certificates of
     common stock of Comstar representing 79% of the number of shares covered by
     outstanding certificates of common stock of Comstar. The assets of Comstar
     consisted primarily of provisional licenses to develop cellular
     communications systems in Cote d'lvoire and Nigeria. The Company has
     recorded the assets acquired and liabilities assumed at their historical
     carrying amounts due to the common control of both companies. The excess of
     liabilities assumed over assets acquired was $72,205. The accompanying
     consolidated financial statements include the results of operations of
     Comstar from the date of acquisition.

     African Communications Incorporated ("ACI") - On March 31, 1995, the
     Company merged with ACI. This transaction was accounted for in a manner
     similar to a pooling of interests because of the common ownership of both
     companies. Prior to March 31, 1995, the Company and ACI were jointly
     developing the Company's cellular systems through subsidiaries of the
     Company that were approximately 67% owned by the Company and 33% owned by
     ACI. The Company and ACI had no operations that were independent of these
     joint development efforts. The Company issued 11,162,255 shares of common
     stock representing a 33% interest in the Company in exchange for all of the
     outstanding shares of ACI. The consolidated financial statements for 1994
     have been restated to include the operations of ACI.

     Karisi Communications, Inc. ("Karisi") - In November 1995, the Company
     acquired Karisi including a 79% equity interest in Karisi Communications
     (Kenya) Ltd. Karisi, which changed its name to Africa Online, Inc., is
     primarily engaged in providing online services to Kenyan subscribers. The
     initial purchase price consisted of 100,000 shares of the Company's common
     stock valued at $2.50 per share and assumption of net liabilities of
     $30,085. Additional consideration of 100,000 shares is currently held in
     escrow and may be released over a two-year period based on the attainment
     of future subscriber levels.

     The acquisition has been accounted for as a purchase. Accordingly, the
     results of operations of Karisi have been included in the accompanying
     consolidated statements of operations from the date of acquisition. The
     excess of purchase over the fair value of net assets acquired has been
     allocated to goodwill.

     The following unaudited pro forma information for the year ended December
     31, 1995 reflects the combined results of operations of the Company and
     Karisi as if the acquisition occurred on January 1, 1995:

       Revenue                $  141,395
       Net loss                3,231,637

     Karisi did not have any significant operations prior to January 1, 1995.

                                                                            F-45

4.   DUE TO STOCKHOLDER - CREDIT FACILITY

     Under a credit facility provided by the Stockholder in 1994, the Company
     was able to borrow up to a maximum of $1,250,000 without interest through
     March 31, 1995 and with interest at prime plus 2% thereafter. On May 31,
     1995, the credit facility was terminated and the outstanding borrowings at
     that date of $1,000,000 were converted into 400,000 shares of common stock.

     Pursuant to a loan and security agreement dated November 15, 1995, the
     Stockholder agreed to make additional loans to the Company in the aggregate
     amount up to $4,500,000. Borrowings bear interest payable monthly at prime
     plus 1.25% on the first $1 million; prime plus 1.5% on the second $1
     million; and prime plus 2% on amounts in excess of $2 million. Borrowings
     are collateralized by all assets of the Company, including a pledge of the
     common stock of the subsidiaries. All borrowings are due on December 31,
     1998. Prior to December 31, 1996, borrowings are convertible into shares of
     the Company's common stock at a conversion price of $3 per share.

     The Company paid the Stockholder a commitment fee equal to 1% of the
     maximum borrowings through the issuance of 15,000 shares of the Company's
     common stock.

5.   INCOME TAXES

     The tax effects of significant items comprising the Company's net deferred
     tax assets as of December 31, 1994 and 1995 are approximately as follows:


                                                          1994           1995

<PAGE>
 
5.   INCOME TAXES (CONTINUED)

     At December 31, 1995, the Company has net operating loss carryforwards for
     federal income tax purposes of $1,673,000 which may be used to offset
     future taxable income, expiring in 2010. The Company also has operating
     loss carryforwards in Cote d'lvoire and Kenya, which begin to expire in
     1998, of $1,696,000, which may be used to offset future taxable income in
     those countries. Due to the uncertainty of realization, the Company has
     provided a 100% valuation allowance of all deferred tax assets.

6.   STOCKHOLDERS' EQUITY

     Stock Recapitalization - On March 31, 1995, the stockholders approved the
     following recapitalization: conversion of the existing outstanding
     preferred stock into common stock at a rate of one and one quarter shares
     of common stock for each share of preferred stock; an increase in the
     number of authorized shares of common stock from 35,000,000 to 70,000,000;
     an increase in the number of authorized shares of preferred stock from
     1,000,000 shares of "Series A" preferred stock to 10,000,000 shares of
     "blank check" preferred stock. In 1996, the Board of Directors and the
     stockholders approved an increase in the authorized shares of common stock
     to 140,000,000 shares.

     Stock Option Plan - Under the Company's 1994 Stock Option Plan (the
     "Plan"), options to purchase up to 6,000,000 shares of common stock may be
     granted to employees, directors, consultants, and advisors of the Company.
     Options granted may be either "incentive stock options" or nonqualified
     options. Stock options are exercisable over a period determined by the
     Board of Directors.

     In 1996, the Board of Directors and the stockholders adopted an amendment
     to the Plan increasing the number of shares available for grant to
     9,500,000.

     A summary of stock option activity is as follows:

                                                 Shares             Price

     Stock Warrants - At December 31, 1995, the Company had outstanding warrants
     to purchase 216,000 shares of the Company's common stock at $2.50 per
     share. The warrants may be exercised at any time and expire in 2005.

                                                                            F-47

7.   COMMITMENTS AND CONTINGENCIES

     As of December 31, 1995, the Company and its subsidiaries leased facilities
     in Ivory Coast and in Cambridge, MA. The leases expire from 1996 to 2000
     and contain renewal options. Future minimum rental payments are as follows:


       Year ended December 31

                                                                     ------

     Total rent expense for the period ended December 31, 1994 and the year
     ended December 31, 1995 was $3,000 and $86,000, respectively.

     At December 31, 1995, the Company has outstanding purchase commitments of
     approximately $4.7 million for equipment relating to its cellular telephone
     development activities in Africa.

     Litigation - Pursuant to the acquisition described in Note 2, holders of
     Comstar stock certificates were required to release Comstar and the Company
     from any claims which such holders may have had and to surrender their
     Comstar stock certificates. Certain holders of the Comstar certificates did
     not participate in the reorganization, and there can be no assurance that
     they will not bring claims against the Company. The consolidated financial
     statements contain no provision or liability for such potential claims;
     however, the Company believes that the reorganization provided the holders
     with the opportunity to acquire equity participation in the Company,
     without further investment, in the same relative proportion as they would
     have had in Comstar. The Company does not expect that this matter will have
     a material impact on its financial position or the results of operations.

8.   SUBSEQUENT EVENTS (UNAUDITED)

     Acquisition of Minority Interest in Subsidiary - In January 1996, the
     Company purchased 90 shares of common stock of Comstar Cellular S.A. Cote
     d'lvoire ("Comstar Cote d'lvoire") from a minority shareholder and employee
     in exchange for 350,000 shares of common stock of the Company and $300,000
     in cash. As a result of this transaction, the Company's equity interest in
     Comstar Cote d'Ivoire increased from 91% to 100%.

     The acquisition will be accounted for as a purchase and the purchase price
     of $1,350,000 is expected to be allocated to goodwill associated with the
     cellular operations of Comstar Cote d'Ivoire.

     Investment in Global Enterprise Services, Inc. ("GES") - In 1996, the
     Company acquired a 48% voting interest in GES, represented by 4,800,000
     shares of convertible preferred stock, for $9 million. The preferred stock
     has voting rights and is convertible into common stock of GES stock.

                                                                            F-48
<PAGE>
 
8.   SUBSEQUENT EVENTS (UNAUDITED) (CONTINUED)

     Investment in Global Enterprise Services, Inc. ("GES") (Continued) -The
     Company also received a warrant to purchase up to 1,380,000 additional
     shares of GES' convertible preferred stock at an exercise price of $2.8125
     per share. The warrant is exercisable from January 1, 1997 through June 30,
     1997 only in the event that GES reports both revenues of less than $15
     million and a loss before interest, taxes, depreciation and amortization
     for the year ending December 31, 1996.

     The Company will account for its investment using the equity method since
     essentially all of the capital at risk in GES belongs to the Company.

     Note Payable - In March 1996, the Company borrowed $2 million from Bay
     Networks, Inc. ("Bay Networks") pursuant to an 8-1/4% convertible note.
     Principal and interest are due on the earlier of six months after the
     completion of a private placement with aggregate gross proceeds of at least
     $1,000,000 or March 31, 1997. Bay Networks has the right within 30 days
     after the completion of such a private placement and prior to March 31,
     1997 to convert the principal and interest into common stock at the price
     per share at which the Company's common stock is sold in the private
     placement.

     Private Placement - Subsequent to December 31, 1995, the Company has sold
     in a private placement 1,430,702 shares of common stock resulting in net
     proceeds to the Company of $4,239,707.

     Stock Subscription - Pursuant to a subscription agreement dated February
     20, 1996, as amended, Carso agreed to acquire for cash 7,000,000 shares of

     In addition, Carso may purchase an additional 3,000,000 shares of the
     Company's common stock from existing stockholders.

     Stockholder Advances - Subsequent to December 31, 1995, the Stockholder
     advanced the Company an additional $2,900,000 under the terms of the
     existing credit facility (Note 4) and all advances have been converted into
     1,500,000 shares of common stock at $3 per share. The credit facility has
     been terminated.

     Acquisition of Prodigy Services Company - On June 17, 1996, the Company
     acquired the partnership interests of International Business Machines
     Corporation ("IBM") and Sears Roebuck and Co. ("Sears") in Prodigy. The
     Company acquired the assets and assumed liabilities of Prodigy, with the
     exception of certain patents and all obligations and liabilities related to
     employee retirement and other postretirement benefit plans. The purchase
     price was $46.2 million in cash subject to adjustments plus contingent
     convertible notes (the "Contingent Convertible Notes"), payable to IBM and
     Sears.

                                                                            F-49

8.   SUBSEQUENT EVENTS (CONTINUED)

     Acquisition of Prodigy Services Company (Continued) - Commencing December
     1998, the Contingent Convertible Notes accrue interest at $4 million on a
     quarterly basis. Upon the earlier of (i) an initial public offering by the
     Company resulting in gross proceeds of at least $25 million, (ii) an
     acquisition of the Company, (iii) following an initial public offering, the
     Company's market value exceeds $200 million, or (iv) the tenth anniversary
     of the closing date, the Contingent Convertible Notes are convertible into
     shares constituting 15% of the Company's outstanding common stock on a
     fully diluted basis (or 15% of the consideration received in the event the
     Company is acquired), limited to a value equal to $200 million plus accrued
     interest. Principal and interest are not required to be paid in cash,
     except in the event that the Company is acquired for cash.

     As part of the above agreement, the Company is required to have available
     funds in the amount of $155 million to provide a portion of the necessary
     funds for the purchase and operations of Prodigy. In order to meet this
     requirement, the Company entered into a funding agreement with Carso and
     the Stockholder described below.

     Commencing with the Prodigy closing and terminating on the earlier of (i)
     November 12, 1997 or (ii) the closing of an underwritten public offering in
     which the gross proceeds to the Company exceed $25 million, the Company has
     the right from time to time to require Carso and the Stockholder to
     purchase shares of common stock from the Company at $6 per share up to a
     maximum amount of $144.5 million (the "Maximum Amount"). The Maximum Amount
     is reduced by (i) the net amount realized from the sale by the Company of
     certain cellular assets (see below), (ii) the net amount realized, after
     expenses, from the sale of common stock in a private placement, (iii) the
     net amount realized by the Company in an initial public offering, (iv) the
     amount realized by the Company from the exercise of the warrants described
     below. The Maximum Amount is allocated 90% to Carso and 10% to the
     Stockholder.

     The Company has granted Carso and the Stockholder warrants to purchase
     2,700,000 shares and 270,000 shares, respectively, of common stock at $3
     per share after the initial closing of a private placement and on or before
     December 31, 1996. Warrants to purchase 2,000,000 shares and 1,000,000
     shares of the Company's common stock were also granted to Carso and the
     Stockholder, respectively, at $9 per share at any time after the initial
     closing of a private placement and on or before the earlier of the closing
     of an initial public offering or November 12, 1997.

     In connection with these arrangements, the Company granted Carso an option
     to purchase, on or before July 26, 1996, its cellular telephone assets
     located in Cote d'lvoire and Guinee for a purchase price of $69 million. If
     the option is exercised, Carso will be granted a right of first refusal,
     from January 1, 1997 to March 31, 1997, to purchase additional cellular
     assets the Company may have at that time.

                                                                            F-50

     Credit Facility - In June 1996, the Company entered into a loan agreement
     with Banco Inbursa, S.A. ("Inbursa"), an affiliate of Carso, whereby
     Inbursa agreed to provide a credit facility to the Company of up to $50
     million for a period of one year at an interest rate of prime plus 1/2%.
     Borrowings under this credit facility are collateralized by a pledge of
     17,000,000 shares of the Company's common stock held by two of the
     Company's stockholders. Any outstanding borrowings mature within 30 days of
     the date of borrowing at which time the Company may re-borrow any unpaid
     balances. Through June 17, 1996, the Company had borrowed $48 million under
     the agreement primarily to fund the Prodigy acquisition.

     Reorganization - On June 13, 1996, a reorganization was effected through
     which the Company became a wholly owned subsidiary of a new holding
     company, Prodigy, Inc.

     *to be filed by amendment

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

   Article EIGHTH of the Registrant's Certificate of Incorporation, as amended
(the "Certificate of Incorporation"), provides that no director of the
Registrant shall be personally liable for any monetary damages for any breach of
fiduciary duty as a director, except to the extent that the Delaware General
Corporation Law prohibits the elimination or limitation of liability of
directors for breach of fiduciary duty.

   Article NINTH of the Registrant's Certificate of Incorporation provides that
a director or officer of the Registrant (a) shall be indemnified by the
Registrant against all expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement incurred in connection with any litigation or
other legal proceeding (other than an action by or in the right of the
Registrant) brought against him by virtue of his position as a director or
officer of the Registrant if he acted in good faith and in a manner he
reasonably believed to be in, or not opposed to, the best interests of the
Registrant, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful and (b) shall be
indemnified by the Registrant against all expenses (including attorneys' fees)
and amounts paid in settlement incurred in connection with any action by or in
the right of the Registrant brought against him by virtue of his position as a
director or officer of the Registrant if he acted in good faith and in a manner
he reasonably believed to be in, or not opposed to, the best interests of the
Registrant, except that no indemnification shall be made with respect to any
matter as to which such person shall have been adjudged to be liable to the
Registrant, unless a court determines that, despite such adjudication but in
view of all of the circumstances, he is entitled to indemnification of such
expenses. Notwithstanding the foregoing, to the extent that a director or
officer has been successful, on the merits or otherwise, including, without
limitation, the dismissal of an action without prejudice, he is required to be
indemnified by the Registrant against all expenses (including attorneys' fees)
incurred in connection therewith. Expenses shall be advanced to a director or
officer at his request, provided that he undertakes to repay the amount advanced
if it is ultimately determined that he is not entitled to indemnification for
such expenses.

                                     II-1
<PAGE>
 
   Indemnification is required to be made unless the Registrant determines that
the applicable standard of conduct required for indemnification has not been
met. In the event of a determination by the Registrant that the director or
officer did not meet the applicable standard of conduct required for
indemnification, or if the Registrant fails to make an indemnification payment
within 60 days after such payment is claimed by such person, such person is
permitted to petition the court to make an independent determination as to
whether such person is entitled to indemnification. As a condition precedent to
the right of indemnification, the director or officer must give the Registrant
notice of the action for which indemnity is sought and the Registrant has the
right to participate in such action or assume the defense thereof.

   Article NINTH of the Registrant's Certificate of Incorporation further
provides that the indemnification provided therein is not exclusive, and
provides that in the event that the Delaware General Corporation Law is amended
to expand the indemnification permitted to directors or officers the Registrant
must indemnify those persons to the fullest extent permitted by such law as so
amended.

   Section 145 of the Delaware General Corporation Law provides that a
corporation has the power to indemnify a director, officer, employee or agent of
the corporation and certain other persons serving at the request of the
corporation in related capacities against amounts paid and expenses incurred in
connection with an action or proceeding to which he is or is threatened to be
made a party by reason of such position, if such person shall have acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests of the corporation, and, in any criminal proceeding, if such person
had no reasonable cause to believe his conduct was unlawful; provided that, in
the case of actions brought by or in the right of the corporation, no
indemnification shall be made with respect to any matter as to which such person
shall have been adjudged to be liable to the corporation unless and only to the
extent that the adjudicating court determines that such indemnification is
proper under the circumstances.

   Under Section        of the Purchase Agreement, the Underwriters are 
obligated, under certain circumstances, to indemnify directors and officers of
the Registrant against certain liabilities, including liabilities under the
Securities Act of 1933, as amended (the "Securities Act").  Reference is made to
the form of Purchase Agreement filed as Exhibit 1.1 hereto.

   The Registrant has an insurance policy with coverage of $8,000,000 that
insures the directors and officers of the Registrant against certain liabilities
which might be incurred by such directors and officers in connection with the
performance of their duties.

ITEM 17.  UNDERTAKINGS

     (a) The undersigned Registrant hereby undertakes to provide to the
Underwriters at the closing specified in the Purchase Agreement, certificates in
such denominations and registered in such names as required by the Underwriters
to permit prompt delivery to each purchaser.

     (b) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions contained in the Certificate of
Incorporation, as amended, of the Registrant and the laws of the State of
Delaware, or otherwise, the Registrant has been advised that in the opinion of
the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable.  In
the event that a claim for indemnification against such liabilities (other than
the payment by the Registrant of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the Registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of 

                                      II-8
<PAGE>
 
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed by
the final adjudication of such issue.

     (c) The undersigned Registrant hereby undertakes that:

      (1) For purposes of determining any liability under the Securities Act,
the information omitted form the form of prospectus filed as part of this
Registration Statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this Registration
Statement as of the time it was declared effective.

      (2) For the purpose of determining any liability under the Securities Act,
each post-effective amendment that contains a form of prospectus shall be deemed
to be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

to time by the Board of Directors of the Corporation in accordance with the
provisions of the General Corporation Law of the State of Delaware.

     The following is a statement of the designations and the powers, privileges
and rights, and the qualifications, limitations or restrictions thereof in
respect of each class of capital stock of the Corporation.

A.   COMMON STOCK.
     ------------ 

     1.   General.  The voting, dividend and liquidation rights of the holders
          -------                                                             
of the Common Stock are subject to and qualified by the rights of the holders of
the Preferred Stock of any series as may be designated by the Board of Directors
upon any issuance of the Preferred Stock of any series.

     2.   Voting.  The holders of the Common Stock are entitled to one vote for
          ------                                                               
each share held at all meetings of stockholders (and written actions in lieu of
meetings).  There shall be no cumulative voting.

          The number of authorized shares of Common Stock may be increased or

entitled 
<PAGE>
 
to vote, irrespective of the provisions of section 242(b)(2) of the General
Corporation Law of Delaware.

     3.   Dividends.  Dividends may be declared and paid on the Common Stock
          ---------

Directors and subject to any preferential dividend rights of any then
outstanding Preferred Stock.

     4.   Liquidation.  Upon the dissolution or liquidation of the Corporation,
          -----------                                                          
whether voluntary or involuntary, holders of Common Stock will be entitled to
receive all assets of the Corporation available for distribution to its
stockholders, subject to any preferential rights of any then outstanding
Preferred Stock.

B.   PREFERRED STOCK.
     --------------- 

     Preferred Stock may be issued from time to time in one of more series, each
of such series to have such terms as stated or expressed herein and in the
resolution or resolutions providing for the issue of such series adopted by the
Board of Directors of the Corporation as hereinafter provided.  Any shares of
Preferred Stock which may be redeemed, purchased or acquired by the Corporation
may be reissued except as otherwise provided by law.  Different series of
Preferred Stock shall not be construed to constitute different classes of shares
for the purposes of voting by classes unless expressly provided.

     Authority is hereby expressly granted to the Board of Directors from time
to time to issue the Preferred Stock in one or more series, and in connection
with the creation of any such series, by resolution or resolutions providing for
the issue of the shares thereof, to determine and fix such voting powers, full
or limited, or no voting powers, and such designations, preferences and relative
participating, optional or other special rights, and qualifications, limitations
or restrictions thereof, including without limitation thereof, dividend rights,
special voting rights, conversion rights, redemption privileges and liquidation
preferences, as shall be stated and expressed in such resolutions, all to the
full extent now or hereafter permitted by the General Corporation Law of
Delaware.  Without limiting the generality of the foregoing, the resolutions
providing for issuance of any series of Preferred Stock may provide that such
series shall be superior or rank equally or be junior to the Preferred Stock of
any other series to the extent permitted by law.  Except as otherwise
specifically provided in this Certificate of Incorporation, no vote of the
holders of the Preferred Stock or Common Stock shall be a prerequisite to the
issuance of any shares of any series of the Preferred Stock authorized by and
complying with the conditions of this Certificate of Incorporation, the right to
have such vote being expressly waived by all present and future holders of the
capital stock of the Corporation.

     SEVENTH.  Whenever a compromise or arrangement is proposed between this
Corporation and its creditors or any class of them and/or between this
corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary

party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the Corporation), by
reason of the fact that he is or was, or has agreed to become, a director or
officer of the Corporation, or is or was serving, or has agreed to serve, at the
request of the Corporation, as a director, officer or trustee of, or in a
similar capacity with, another corporation, partnership, joint venture trust or
other enterprise (including any employee benefit plan) (all such persons being
referred to hereafter as an "Indemnitee"), or by reason of any action alleged to
have been taken or omitted in such capacity, against all expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by him or on his behalf in connection with such action, suit
or proceeding and any appeal therefrom, if he acted in good faith and in a
manner he reasonably believed to be in, or not opposed to, the best interests of
the Corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.  The termination of any
action, suit or proceeding by judgment, order, settlement, conviction or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
        ---- ----------                                                  
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in, or not opposed to, the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful. Notwithstanding
anything to the contrary in this Article, except as set forth in Section 7
below, the Corporation shall not indemnify an Indemnitee seeking indemnification
in connection with a proceeding (or part thereof) initiated by the Indemnitee
unless the initiation thereof was approved by the Board of Directors of the
Corporation.
 
     2.  Actions or Suits by or in the Right of the Corporation.  The
         ------------------------------------------------------      
Corporation shall indemnify any Indemnitee who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the Corporation to procure a judgment in its favor by
reason of the fact that he is or was, or has agreed to become, a director or
officer of the Corporation, or is or was serving, or has agreed to serve, at the
request of the Corporation, as a director, officer or trustee of, or in a
similar capacity with, another corporation, partnership, joint venture, trust or
other enterprise (including any employee benefit plan), or by reason of any
action alleged to have been taken or omitted in such capacity, against all
expenses (including attorneys' fees) and amounts paid in settlement actually and
reasonably incurred by him or on his behalf in connection with such action, suit
or proceeding and any appeal therefrom, if he acted in good faith and in a
manner he reasonably believed to be in, or not opposed to, the best interests of
the Corporation, except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the Corporation unless and only to the extent that the Court of
Chancery of Delaware or the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of such liability but
in view of all the circumstances of the case, such person is fairly and
reasonably entitled to indemnity for such expenses (including 
<PAGE>
 
attorneys' fees) which the Court of Chancery of Delaware or such other court
shall deem proper.

     3.   Indemnification for Expenses of Successful Party.  Notwithstanding the
          ------------------------------------------------                      
other provisions of this Article, to the extent that an Indemnitee has been
successful, on the merits or otherwise, in defense of any action, suit or
proceeding referred to in Sections 1 and 2 of this Article, or in defense of any
claim, issue or matter therein, or on appeal from any such action, suit or
proceeding, he shall be indemnified against all expenses (including attorneys'
fees) actually and reasonably incurred by him or on his behalf in connection
therewith.  Without limiting the foregoing, if any action, suit or proceeding is
disposed of, on the merits or otherwise (including a disposition without
prejudice), without (i) the disposition being adverse to the Indemnitee, (ii) an
adjudication that the Indemnitee was liable to the Corporation, (iii) a plea of
guilty or nolo contendere by the Indemnitee, (iv) an adjudication that the
          ---- ----------                                                 
Indemnitee did not act in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the Corporation, and (v) with
respect to any criminal proceeding, an adjudication that the Indemnitee had
reasonable cause to believe his conduct was unlawful, the Indemnitee shall be
considered for the purposes hereof to have been wholly successful with respect
thereto.

     4.   Notification and Defense of Claim.  As a condition precedent to his
          ---------------------------------                                  
right to be indemnified, the Indemnitee must notify the Corporation in writing
as soon as practicable of any action, suit, proceeding or investigation
involving him for which indemnity will or could be sought.  With respect to any
action, suit, proceeding or investigation of which the Corporation is so
notified, the Corporation will be entitled to participate therein at its own
expense and/or to assume the defense thereof at its own expense, with legal
counsel reasonably acceptable to the Indemnitee.  After notice from the
Corporation to the Indemnitee of its election so to assume such defense, the
Corporation shall not be liable to the Indemnitee for any legal or other
expenses subsequently incurred by the Indemnitee in connection with such claim,
other than as provided below in this Section 4.  The Indemnitee shall have the
right to employ his own counsel in connection with such claim, but the fees and
expenses of such counsel incurred after notice from the Corporation of its
assumption of the defense thereof shall be at the expense of the Indemnitee
unless (i) the employment of counsel by the Indemnitee has been authorized by
the Corporation, (ii) counsel of the Indemnitee shall have reasonably concluded
that there may be a conflict of interest or position on any significant issue
between the Corporation and the Indemnitee in the conduct of the defense of such
action or (iii) the Corporation shall not in fact have employed counsel to
assume the defense of such action, in each of which cases the fees and expenses
of counsel for the Indemnitee shall be at the expense of the Corporation, except
as otherwise expressly provided by this Article. The Corporation shall not be
entitled, without the consent of the Indemnitee, to assume the defense of any
claim brought by or in the right of the Corporation or as to which counsel for
the Indemnitee shall have reasonably made the conclusion provided for in clause
(ii) above.
<PAGE>
 
     5.   Advance of Expenses.  Subject to the provisions of Section 6 below, in
          -------------------                                                   
the event that the Corporation does not assume the defense pursuant to Section 4
of this Article or any action, suit, proceeding or investigation of which the
Corporation receives notice under this Article, any expenses (including
attorneys' fees) incurred by an indemnitee in defending a civil or criminal
action, suit, proceeding or investigation or any appeal therefrom shall be paid
by the Corporation in advance of the final disposition of such matter, provided,
                                                                       -------- 
however, that the payment of such expenses incurred by an Indemnitee in advance
- -------                                                                        
of the final disposition of such matter shall be made only upon receipt of an
undertaking by or on behalf of the Indemnitee to repay all amounts so advanced
in the event that it shall ultimately be determined that the Indemnitee is not
entitled to be indemnified by the Corporation as authorized in this Article.
Such undertaking may be accepted without reference to the financial ability of
such person to make such repayment.

     6.   Procedure for Indemnification.  In order to obtain indemnification or
          -----------------------------                                        
advancement of expenses pursuant to Section 1, 2, 3 or 5 of this Article, the
Indemnitee shall submit to the corporation a written request, including in such
request such documentation and information as is reasonably available to the
Indemnitee and is reasonably necessary to determine whether and to what extent
the Indemnitee is entitled to indemnification or advancement of expenses.  Any
such indemnification or advancement of expenses shall be made promptly, and in
any event within 60 days after receipt by the Corporation of the written request
of the Indemnitee, unless with respect to requests under Section 1, 2 or 5 the
Corporation determines within such 60-day period that the Indemnitee did not
meet the applicable standard of conduct set forth in Section 1 or 2, as the case
may be.  Such determination shall be made in each instance by (a) a majority
vote of a quorum of the directors of the Corporation consisting of persons who
are not at that time parties to the action, suit or proceeding in question
("disinterested directors"), (b) if no such quorum is obtainable, a majority
vote of a committee of two or more disinterested directors, (c) a majority vote
of a quorum of the outstanding shares of stock of all classes entitled to vote
for directors, voting as a single class, which quorum shall consist of
stockholders who are not at that time parties to the action, suit or proceeding
in question, (d) independent legal counsel (who may be regular legal counsel to
the Corporation), or (e) a court of competent jurisdiction.

     7.   Remedies.  The right to indemnification or advances as granted by this
          --------                                                              
Article shall be enforceable by the Indemnitee in any court of competent
jurisdiction if the Corporation denies such request, in whole or in part, or if
no disposition thereof is made within the 60-day period referred to above in
Section 6.  Unless otherwise required by law, the burden of proving that the
Indemnitee is not entitled to indemnification or advancement of expenses under
this Article shall be on the Corporation.  Neither the failure of the
Corporation to have made a determination prior to the commencement of such
action that indemnification is proper in the circumstances because the
Indemnitee has met the applicable standard of conduct, nor an actual
determination by the Corporation pursuant to Section 6 that the Indemnitee has
not met such applicable standard of conduct, shall be a defense to the 
<PAGE>
 
action or create a presumption that the Indemnitee has not met the applicable
standard of conduct. The indemnitee's expenses (including attorneys' fees)
incurred in connection with successfully establishing his right to
indemnification, in whole or in part, in any such proceeding shall also be
indemnified by the Corporation.

     8.   Subsequent Amendment.  No amendment, termination or repeal of this
          --------------------                                              
Article or of the relevant provisions of the General Corporation Law of Delaware
or any other applicable laws shall affect or diminish in any way the rights of
any Indemnitee to indemnification under the provisions hereof with respect to
any action, suit, proceeding or investigation arising out of or relating to any
actions, transactions or facts occurring prior to the final adoption of such
amendment, termination or repeal.

     9.   Other Rights.  The indemnification and advancement of expenses
          ------------                                                  
provided by this Article shall not be deemed exclusive of any other rights to
which an Indemnitee seeking indemnification or advancement of expenses may be
entitled under any law (common or statutory), agreement or vote of stockholders
or disinterested directors or otherwise, both as to action in his official
capacity and as to action in any other capacity while holding office for the
Corporation, and shall continue as to an Indemnitee who has ceased to be a
director or officer, and shall inure to the benefit of the estate, heirs,
executors and administrators of the Indemnitee.  Nothing contained in this
Article shall be deemed to prohibit, and the Corporation is specifically
authorized to enter into, agreements with officers and directors providing
indemnification rights and procedures different from those set forth in this
Article.  In addition, the Corporation may, to the extent authorized from time
to time by its Board of Directors, grant indemnification rights to other
employees or agents of the Corporation or other persons serving the Corporation
and such rights may be equivalent to, or greater or less than, those set forth
in this Article.

     10.  Partial Indemnification.  If an Indemnitee is entitled under any
          -----------------------                                         
provision of this Article to indemnification by the Corporation for some or a
portion of the expenses (including attorneys' fees), judgments, fines or amounts
paid in settlement actually and reasonably incurred by him or on his behalf in
connection with any action, suit, proceeding or investigation and any appeal
therefrom but not, however, for the total amount thereof, the Corporation shall
nevertheless indemnify the Indemnitee for the portion of such expenses
(including attorneys' fees), judgments, fines or amounts paid in settlement to
which the Indemnitee is entitled.

     11.  Insurance.  The Corporation may purchase and maintain insurance, at
          ---------                                                          
its expense, to protect itself and any director, officer, employee or agent of
the Corporation or another corporation, partnership, joint venture, trust or
other enterprise (including any employee benefit plan) against any expense,
liability or loss incurred by him in any such capacity, or arising out of his
status as such, whether or not the Corporation would have the power to indemnify
such person against such expense, liability or loss under the General
Corporation Law of Delaware.
<PAGE>
 
     12.  Merger or Consolidation.  If the Corporation is merged into or
          -----------------------                                       
consolidated with another corporation and the Corporation is not the surviving
corporation, the surviving corporation shall assume the obligations of the
Corporation under this Article with respect to any action, suit, proceeding or
investigation arising out of or relating to any actions, transactions or facts
occurring prior to the date of such merger or consolidation.

     13.  Savings Clause.  If this Article or any portion hereof shall be
          --------------                                                 
invalidated on any ground by any court of competent jurisdiction, then the
Corporation shall nevertheless indemnify each Indemnitee as to any expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement in
connection with any action, suit, proceeding or investigation, whether civil,
criminal or administrative, including an action by or in the right of the
Corporation, to the fullest extent permitted by any applicable portion of this
Article that shall not have been invalidated and to the fullest extent permitted
by applicable law.

     14.  Definitions.  Terms used herein and defined in Section 145(h) and
          -----------                                                      
Section 145(i) of the General Corporation Law of Delaware shall have the
respective meanings assigned to such terms in such Section 145(h) and Section
145(i).

     15.  Subsequent Legislation.  If the General Corporation Law of Delaware is
          ----------------------                                                
amended after adoption of this Article to expand further the Indemnification
permitted to Indemnitees, then the Corporation shall indemnify such persons to
the fullest extent permitted by the General Corporation Law of Delaware, as so
amended.

     TENTH.  The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this Certificate of Incorporation, in the
manner now or hereafter prescribed by statute and this Certificate of
Incorporation, and all rights conferred upon stockholders herein are granted
subject to this reservation.

                           ARTICLE 1 -- Stockholders
                           -------------------------


     1.1  Place of Meetings.  All meetings of stockholders shall be held at such
          -----------------                                                     
place within or without the State of Delaware as may be designated from time to
time by the Board of Directors or the President or, if not so designated, at the
registered office of the corporation.

     1.2  Annual Meeting.  The annual meeting of stockholders for the election
          --------------                                                      
of directors and for the transaction of such other business as may properly be
brought before the meeting shall be held on a date to be fixed by the Board of
Directors or the President (which date shall not be a legal holiday in the place
where the meeting is to be held) at the time and place to be fixed by the Board
of Directors or the President and stated in the notice of the meeting.  If no
annual meeting is held in accordance with the foregoing provisions, the Board of
Directors shall cause the meeting to be held as soon thereafter as convenient.
If no annual meeting is held in accordance with the foregoing provisions, a
special meeting may be held in lieu of the annual meeting, and any action taken
at that special meeting shall have the same effect as if it had been taken at
the annual meeting, and in such case all references in these By-Laws to the
annual meeting of the stockholders shall be deemed to refer to such special
meeting.

     1.3  Special Meetings.  Special meetings of stockholders may be called at
          ----------------                                                    
any time by the President or by the Board of Directors.  Business transacted at
any special meeting of stockholders shall be limited to matters relating to the
purpose or purposes stated in the notice of meeting.

     1.4  Notice of Meetings.  Except as otherwise provided by law, written
          ------------------                                               
notice of each meeting of stockholders, whether annual or special, shall be
given not less than 10 nor more than 60 days before the date of the meeting to
each stockholder entitled to vote at such meeting.  The notices of all meetings
shall state the place, date and hour of the meeting.  The notice of a special
meeting shall state, in addition, the purpose or purposes for which the meeting
is called.  If mailed, notice is given when deposited in the United States mail,
postage prepaid, directed to the stockholder at his address as it appears on the
records of the corporation.

     1.5  Voting List.  The officer who has charge of the stock ledger of the
          -----------                                                        
corporation shall prepare, at least 10 days before every meeting of
stockholders, a 
<PAGE>
 
complete list of the stockholders entitled to vote at the meeting, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder. Such list shall be open to
the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least 10 days prior to the
meeting, at a place within the city where the meeting is to be held. The list
shall also be produced and kept at the time and place of the meeting during the
whole time of the meeting, and may be inspected by any stockholder who is
present.

     1.6  Quorum.  Except as otherwise provided by law, the Certificate of
          ------                                                          
Incorporation or these By-Laws, the holders of a majority of the shares of the
capital stock of the corporation issued and outstanding and entitled to vote at
the meeting, present in person or represented by proxy, shall constitute a
quorum for the transaction of business.

     1.7  Adjournments.  Any meeting of stockholders may be adjourned to any
          ------------                                                      
other time and to any other place at which a meeting of stockholders may be held
under these By-Laws by the stockholders present or represented at the meeting
and entitled to vote, although less than a quorum, or, if no stockholder is
present, by any officer entitled to preside at or to act as Secretary of such
meeting.  It shall not be necessary to notify any stockholder of any adjournment
of less than 30 days if the time and place of the adjourned meeting are
announced at the meeting at which adjournment is taken, unless after the
adjournment a new record date is fixed for the adjourned meeting.  At the
adjourned meeting, the corporation may transact any business which might have
been transacted at the original meeting.

     1.8  Voting and Proxies.  Each stockholder shall have one vote for each
          ------------------                                                
share of stock entitled to vote held of record by such stockholder and a
proportionate vote for each fractional share so held, unless otherwise provided
in the Certificate of Incorporation.  Each stockholder of record entitled to
vote at a meeting of stockholders, or to express consent or dissent to corporate
action in writing without a meeting, may vote or express such consent or dissent
in person or may authorize another person or persons to vote or act for him by
written proxy executed by the stockholder or his authorized agent and delivered
to the Secretary of the corporation. No such proxy shall be voted or acted upon
after three years from the date of its execution, unless the proxy expressly
provides for a longer period.

     1.9  Action at Meeting.  When a quorum is present at any meeting, the
          -----------------                                               
holders of shares of stock representing a majority of the votes cast on a matter
(or if there are two or more classes of stock entitled to vote as separate
classes, then in the case of each such class, the holders of shares of stock of
that class representing a majority of the votes cast on a matter) shall decide
any matter to be voted upon by the stockholders at such meeting, except when a
different vote is required by express provision of law, the Certificate of
Incorporation or these By-Laws.  When a quorum is present at any meeting, any
election by stockholders shall be determined by a plurality of the votes cast on
the election.
<PAGE>
 
     1.10 Action without Meeting.  Any action required or permitted to be taken
          ----------------------                                               
at any annual or special meeting of stockholders of the corporation may be taken
without a meeting, without prior notice and without a vote, if a consent in
writing, setting forth the action so taken, is signed by the holders of
outstanding stock having not less than the minimum number of votes that would be
necessary to authorize or take such action at a meeting at which all shares
entitled to vote on such action were present and voted.  Prompt notice of the
taking of corporate action without a meeting by less than unanimous written
consent shall be given to those stockholders who have not consented in writing.


                             ARTICLE 2 -- Directors
                             ----------------------

     2.1  General Powers.  The business and affairs of the corporation shall be
          --------------                                                       
managed by or under the direction of a Board of Directors, who may exercise all
of the powers of the corporation except as otherwise provided by law or the
Certificate of Incorporation.  In the event of a vacancy in the Board of
Directors, the remaining directors, except as otherwise provided by law, may
exercise the powers of the full Board until the vacancy is filled.

     2.2  Number; Election and Qualification.  The number of directors which
          ----------------------------------                                
shall constitute the whole Board of Directors shall be determined by resolution
of the stockholders or the Board of Directors, but in no event shall be less
than one.  The number of directors may be decreased at any time and from time to
time either by the stockholders or by a majority of the directors then in
office, but only to eliminate vacancies existing by reason of the death,
resignation, removal or expiration of the term of one or more directors.  The
directors shall be elected at the annual meeting of stockholders by such
stockholders as have the right to vote on such election. Directors need not be
stockholders of the corporation.

     2.3  Enlargement of the Board.  The number of directors may be increased at
          ------------------------                                              
any time and from time to time by the stockholders or by a majority of the
directors then in office.

     2.4  Tenure.  Each director shall hold office until the next annual meeting
          ------                                                                
and until his successor is elected and qualified, or until his earlier death,
resignation or removal.

     2.5  Vacancies.  Unless and until filled by the stockholders, any vacancy
          ---------                                                           
in the Board of Directors, however occurring, including a vacancy resulting from
an enlargement of the Board, may be filled by vote of a majority of the
directors then in office, although less than a quorum, or by a sole remaining
director.  A director elected to fill a vacancy shall be elected for the
unexpired term of his predecessor in office, and a director chosen to fill a
position resulting from an increase in the number of directors shall hold office
until the next annual meeting of stockholders 
<PAGE>
 
and until his successor is elected and qualified, or until his earlier death,
resignation or removal.

     2.6  Resignation.  Any director may resign by delivering his written
          -----------                                                    
resignation to the corporation at its principal office or to the President or
Secretary. Such resignation shall be effective upon receipt unless it is
specified to be effective at some other time or upon the happening of some other
event.

     2.7  Regular Meetings.  Regular meetings of the Board of Directors may be
          ----------------                                                    
held without notice at such time and place, either within or without the State
of Delaware, as shall be determined from time to time by the Board of Directors;
provided that any director who is absent when such a determination is made shall
be given notice of the determination.  A regular meeting of the Board of
Directors may be held without notice immediately after and at the same place as
the annual meeting of stockholders.

     2.8  Special Meetings.  Special meetings of the Board of Directors may be
          ----------------                                                    
held at any time and place, within or without the State of Delaware, designated
in a call by the Chairman of the Board, President, two or more directors, or by
one director in the event that there is only a single director in office.

     2.9  Notice of Special Meetings.  Notice of any special meeting of
          --------------------------                                   
directors shall be given to each director by the Secretary or by the officer or
one of the directors calling the meeting.  Notice shall be duly given to each
director (i) by giving notice to such director in person or by telephone at
least 48 hours in advance of the meeting, (ii) by sending a telegram or telex,
or delivering written notice by hand, to his last known business or home address
at least 48 hours in advance of the meeting, or (iii) by mailing written notice
to his last known business or home address at least 72 hours in advance of the
meeting.  A notice or waiver of notice of a meeting of the Board of Directors
need not specify the purposes of the meeting.

     2.10 Meetings by Telephone Conference Calls.  Directors or any members of
          --------------------------------------                              
any committee designated by the directors may participate in a meeting of the
Board of Directors or such committee by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other, and participation by such means shall constitute
presence in person at such meeting.

     2.11 Quorum.  A majority of the total number of the whole Board of
          ------                                                       
Directors shall constitute a quorum at all meetings of the Board of Directors.
In the event one or more of the directors shall be disqualified to vote at any
meeting, then the required quorum shall be reduced by one for each such director
so disqualified; provided, however, that in no case shall less than one-third
(1/3) of the number so fixed constitute a quorum.  In the absence of a quorum at
any such meeting, a majority of the directors present may adjourn the meeting
from time to time without 
<PAGE>
 
further notice other than announcement at the meeting, until a quorum shall be
present.

     2.12 Action at Meeting.  At any meeting of the Board of Directors at which
          -----------------                                                    
a quorum is present, the vote of a majority of those present shall be sufficient
to take any action, unless a different vote is specified by law, the Certificate
of Incorporation or these By-Laws.

     2.13 Action by Consent.  Any action required or permitted to be taken at
          -----------------                                                  
any meeting of the Board of Directors or of any committee of the Board of
Directors may be taken without a meeting, if all members of the Board or
committee, as the case may be, consent to the action in writing, and the written
consents are filed with the minutes of proceedings of the Board or committee.

     2.14 Removal.  Except as otherwise provided by the General Corporation Law
          -------                                                              
of Delaware, any one or more or all of the directors may be removed, with or
without cause, by the holders of a majority of the shares then entitled to vote
at an election of directors, except that the directors elected by the holders of
a particular class or series of stock may be removed without cause only by vote
of the holders of a majority of the outstanding shares of such class or series.

     2.15 Committees.  The Board of Directors may, by resolution passed by a
          ----------                                                        
majority of the whole Board, designate one or more committees, each committee to
consist of one or more of the directors of the corporation.  The Board may
designate one or more directors as alternate members of any committee, who may
replace any absent or disqualified member at any meeting of the committee.  In
the absence or disqualification of a member of a committee, the member or
members of the committee present at any meeting and not disqualified from
voting, whether or not he or they constitute a quorum, may unanimously appoint
another member of the Board of Directors to act at the meeting in the place of
any such absent or disqualified member.  Any such committee, to the extent
provided in the resolution of the Board of Directors and subject to the
provisions of the General Corporation Law of the State of Delaware, shall have
and may exercise all the powers and authority of the Board of Directors in the
management of the business and affairs of the corporation and may authorize the
seal of the corporation to be affixed to all papers which may require it.  Each
such committee shall keep minutes and make such reports as the Board of
Directors may from time to time request.  Except as the Board of Directors may
otherwise determine, any committee may make rules for the conduct of its
business, but unless otherwise provided by the directors or in such rules, its
business shall be conducted as nearly as possible in the same manner as is
provided in these By-Laws for the Board of Directors.

     2.16 Compensation of Directors.  Directors may be paid such compensation
          -------------------------                                          
for their services and such reimbursement for expenses of attendance at meetings
as the Board of Directors may from time to time determine.  No such payment
shall 
<PAGE>
 
preclude any director from serving the corporation or any of its parent or
subsidiary corporations in any other capacity and receiving compensation for

Wireless and hold it harmless against and in respect of any and all payments,
damages, claims, demands, losses, expenses, costs, obligations and liabilities,
(including, without limitation, settlement costs and any other legal, accounting
or other expenses for investigating or defending any actions or threatened
actions) in connection with:

                (a) any breach or failure of Comstar Nevada to perform any
representation and warranty, commitment, obligation, covenant or condition under
this Agreement, any of the Schedules hereunder or any of the agreements
contemplated hereby; or

<PAGE>
 
                (b) any claim arising out of any and all actions taken by
Comstar Nevada prior to the Closing Date.

Comstar Nevada, its officers and directors  shall reimburse International
Wireless on demand for any payment made or loss suffered by International
Wireless at any time after the Closing Date, based upon the judgment of any
court of competent jurisdiction or pursuant to a bona fide compromise or
settlement (which shall be approved by Comstar Nevada, such approval not to be
withheld unreasonably).  No indemnity pursuant to this Section 10 shall be
available until the aggregate amount of all claims made hereunder shall exceed
$25,000 and then shall be available only to the extent that such claims in the
aggregate exceed $100,000.

          10.03 Claims for Indemnification.  Whenever any claim shall arise for
                --------------------------                                     
indemnification under this Section 10, the party seeking indemnification (the
"Indemnified Party") shall promptly notify the party required to indemnify (the
"Indemnifying Party") of the claim and, when known, the facts constituting the
basis for such claim.  In the event of any such claim for indemnification
hereunder resulting from or in connection with any claim or legal proceedings by
a third party, the notice shall specify, if known, the amount or an estimate of
the amount of the liability arising therefrom.  The Indemnified Party shall not
settle or compromise any claim by a third party for which it is entitled to
indemnification hereunder without the prior written consent, which shall not be
unreasonably withheld or delayed, of the Indemnifying Party; provided, however,
                                                             ----------------- 
that if suit shall have been instituted against the Indemnified Party and the
Indemnifying Party shall not have taken control of such suit after notification
thereof as provided in Subsection 10.04 of this Agreement, the Indemnified Party
shall have the right to settle or compromise such claim upon giving notice to
the Indemnifying Party as provided in this Subsection 10.03.

          10.04 Defense by the Indemnifying Party.  In connection with any claim
                ---------------------------------                               
which may give rise to indemnity hereunder resulting from or arising out of any
claim or legal proceeding by a person other than the Indemnified Party, the
Indemnifying Party, at the sole cost and expense of the Indemnifying Party, may,
upon written notice to the Indemnified Party, assume the defense of any such
claim or legal proceeding if the Indemnifying Party acknowledges to the
Indemnified Party in writing the obligation of the Indemnifying Party to
indemnify the Indemnified Party with respect to all elements of such claim.  If
the Indemnifying Party assumes the defense of any such claim or legal
proceeding, the Indemnifying Party shall select counsel reasonably acceptable to
the Indemnified Party to conduct the defense of such claims or legal proceedings
and at the sole cost and expense of the Indemnifying Party shall take all steps
necessary in the defense or settlement thereof.  The Indemnifying Party shall
not consent to a settlement of, or the entry of any judgment arising from, any
such claim or legal proceeding, without the prior written consent of the
Indemnified Party (which consent shall not be unreasonably withheld or delayed).
The Indemnified Party shall be entitled to participate in (but not control) the
defense of any such action, with its own counsel and at its own expense.  If the
Indemnifying Party does not assume the defense of any such claim or litigation
resulting therefrom within 30 days after the date such claim is made:  (a) the
Indemnified Party may defend against such claim or litigation in such manner as
it may deem appropriate, including, but not limited to, settling such claim or
litigation, after giving notice of the same to the Indemnifying Party, on such
terms as the Indemnified Party may deem appropriate, and (b) the Indemnifying
Party shall be entitled to participate in (but not control) the defense of such
action, with its counsel and at its own expense.

          10.05 Payment of Indemnification Obligation.  All indemnification by
                -------------------------------------                         
the parties hereunder, shall be effected by payment of cash or delivery of a
cashier's or certified check in the amount of the indemnification liability.

          10.06 Survival of Representations; Claims for Indemnification.  All
                -------------------------------------------------------      
representations and warranties made by Comstar Nevada or International Wireless
in this Agreement, or in any instrument or document furnished in connection with
this Agreement or the transactions contemplated hereby, shall survive the
Closing for a period of one year.  All such representations and warranties shall
expire on the one year anniversary of the Closing Date, except for claims, if
any, asserted in writing prior to such one year anniversary identified as a
claim for indemnification pursuant to this Section 10.

     11.  Termination of Agreement.
          ------------------------ 

          This Agreement may be terminated by the mutual written agreement of
the parties hereto at any time prior to the Closing Date.  In the event of such
termination by agreement, Comstar Nevada shall have no further obligation or
liability to International Wireless under this Agreement and International
Wireless shall have no further obligation to Corns tar Nevada under this
Agreement.

as set forth in the last sentence of this Section 9.4. With respect to any
employee of the Company terminated without cause within twelve months following

Buyer (after the Closing), as appropriate, shall prepare and timely file (or
cause to be prepared and timely filed) for the Company all tax returns and
reports of the Company for all taxable periods.  All such tax returns and
reports for all Pre-Closing Taxable Periods and Straddle Periods shall be
prepared in a manner consistent with the Company's past tax practices and prior
tax returns and reports filed by the Company, except as otherwise required by
law.  The Company and Buyer shall not (x) defer or shift deductions and other
similar items out of Pre-Closing Taxable Periods or (y) accelerate or shift
income and other similar items into Pre-Closing Taxable Periods, through
original or amended tax returns or reports.  The Company and Buyer may not amend

Period or Straddle Period without the prior written consent of each Seller
(which consent may be withheld in either Seller's sole discretion, except that
consent to amendments required to correct mathematical errors shall not be
unreasonably withheld).  Sellers shall cooperate and assist the Company and
Buyer in the preparation and filing of all such tax returns and reports and any
related applications for automatic or other extensions of time to file such
income tax returns and reports.  All items of income, gain, loss, deduction and
credit for any Straddle Period shall be allocated between the Pre- and Post-

to and including the Closing Date

such income tax returns and reports for Pre-Closing Taxable Periods and Straddle
Periods not less than 20 days prior to the filing thereof. Sellers, the Company
and Buyer shall in good faith consult with each other and their respective tax
advisors in an effort to resolve any differences with respect to the preparation
and accuracy of such tax returns and reports for Pre-Closing Taxable Periods and
Straddle Periods and all tax items reflected thereon; provided, however, that

estate transfer taxes or equivalent state or local taxes, including the New York
transfer gains tax, incurred in connection with this transaction up to an amount
not to exceed $50,000. Buyer and Sellers shall, respectively, be responsible for

upon receipt of any notice of any pending or threatened audit, litigation or
other contest (a "Contest") with respect to any Pre-Closing Taxable Period or

the Sellers with respect to such Taxable Period as a result of their ownership
of partnership interests in the Company or any items of income, gain, loss,
deduction or credit allocable to the Sellers with respect to the assets and
operations of the Company with respect to such Taxable Period.  Sellers shall
have the sole right to control, and to represent the interests of all affected
taxpayers in, any such Contest with respect to any Pre-Closing Taxable Period or
Straddle Period and to employ counsel of their choice at their expense;
provided, however, that Buyer shall have the right to participate in (but not
control) any such Contest at its own expense.  The Company and Buyer (i) shall
execute and deliver to the Sellers or their designated counsel or other
representatives such powers of attorney and other documents as may be reasonably
necessary to permit Sellers to so control any such Contest, (ii) shall provide
such other documents, certificates, information, testimony and assistance as may
be reasonably requested by Sellers in connection with any such Contest and (iii)
except as authorized by Sellers, shall not take any action (including the
execution of extensions of statutes of limitations) in relation to, or at the
request of, any taxing authority with respect to any such Contest.

          The Company or the Buyer, as appropriate, shall pay (or cause to be
paid) all taxes shown to be due and payable by the Company on all of its tax
returns and reports.  Sellers shall be solely responsible for all taxes imposed
upon them and arising from their status as partners of the Company for all Pre-
Closing Taxable Periods.

          For purposes of this Section 9.5, "taxes" shall mean any domestic or
foreign net income, gross income, gross receipts, sales, use, excise, franchise,
transfer, payroll, stamp, gains, capital, premium, property or windfall profits
tax, alternative, add-on or other minimum tax, value added, or other tax, fee or
assessment, together with any interest and any penalty, addition to tax or
additional amount imposed by any taxing authority, whether any such tax is
imposed directly or through withholding.  For purposes of this Section 9.5,
"Pre-Closing Taxable Period" shall mean any taxable period of the Company (or,
in the case of a Straddle Period, the portion thereof) that begins before and
ends on or before the Closing Date; "Post-Closing Taxable Period" shall mean any
taxable period of the Company (or, in the case of a Straddle Period, the portion
thereof) that begins after and ends after the Closing Date; and "Straddle
Period" shall mean any taxable period of the Company that begins before and ends

                                             Services Company as the "Company",
                                             and International Wireless
                                             Incorporated as "Buyer", to the
                                             Partnership Purchase Agreement (the
                                             "Agreement") dated May 12, 1996,
                                             among such parties.

          The parties agree that:

          1.   The following definition in Section 1.1 of the Agreement is
amended to read as follows:

          "Closing Date" shall mean June 17, 1996.
          -------------                           

          2.   The following definition in Section 2.3(a) is amended to read, in
its entirety, as follows:

          "the cash Purchase Price shall be increased by (i) the amount of all

minus (ii) $650,000."

          3.   Buyer shall pay, be delivery to the Company in immediately

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

                            NOTE EXCHANGE AGREEMENT


     NOTE EXCHANGE AGREEMENT (this "Agreement"), entered into on this 20th day
of October, 1997, among Prodigy, Inc., a Delaware corporation (the "Company"),
Prodigy Services Corporation, a Delaware corporation and an indirect wholly-
owned subsidiary of the Company formerly known as Prodigy Acquisition
Corporation ("PSC"), Sears, Roebuck and Co., a New York corporation ("Sears"),
and International Business Machines Corporation, a New York corporation ("IBM")
(Sears and IBM are collectively or alternatively referred to herein as the
"Sellers").

     WHEREAS, the Company (as assignee of International Wireless Incorporated),
Prodigy Services Company, a New York general partnership ("Old Prodigy"), and
the Sellers are parties to a Partnership Purchase Agreement dated as of May 12,
1996 and amended as of June 3, 1996 (as so amended, the "Purchase Agreement")
pursuant to which PSC purchased all of the partnership interests (the
"Partnership Interests") in Old Prodigy from the Sellers;

     WHEREAS, simultaneously with the purchase of the Partnership Interests by
PSC, the Company issued to each Seller an 8% Contingent Convertible Promissory
Note dated June 17, 1996 in the face amount of $100,000,000 (individually, an
"Old Note" and collectively, the "Old Notes"); and

     WHEREAS, the parties wish to modify the Old Notes and related arrangements;

     NOW, THEREFORE, in consideration of the undertakings and commitments
contained herein and other good and valuable consideration, the sufficiency of
which is acknowledged, the parties agree as follows:

     1.   Exchange of Old Notes.  At the Closing (as defined below), each Old
          ---------------------                                              
Note shall be exchanged for (i) an 8% Contingent Convertible Promissory Note in
the face amount of $100,000,000 issued by PSC in the form of Exhibit A attached
                                                             ---------         
hereto (individually, a "New Note" and collectively, the "New Notes") and (ii) a
Contingent Common Stock Purchase Warrant granted by PSC in the form of Exhibit B
                                                                       ---------
attached hereto (individually, a "Warrant" and collectively, the "Warrants").
Effective as of the Closing, the Sellers hereby release the Company from all
obligations under the Old Notes.

     2.   Lease Arrangements.
          ------------------ 

          (a) Prepayment of Obligations.  PSC shall terminate, not later than
              -------------------------                                      
December 31, 1997, PSC's existing lease with Metropolitan Life Insurance Company
("Landlord") covering PSC's facility at 445 Hamilton Avenue, White Plains, New
York (the "Lease").  PSC shall timely perform all of its obligations under the
Lease and vacate the premises covered by the Lease not later than December 31,
1997.  Prior to Closing, Carso Global Telecom, S.A. de C.V. ("Carso") shall
prepay to the Landlord in full all rent due and to become due under the Lease
through December 31, 1997, together with the entire amount of the early
termination fee provided under the Lease, less any negotiated discount for
prepayment agreed to by the Landlord (the net amount of the foregoing, the
"Lease Amount").  At Closing, Carso shall deliver to the Sellers the Termination
Deposit (as defined in Section 2(b) below), together with evidence reasonably
satisfactory to Sellers that the Lease Amount has been fully paid to the
Landlord.

          (b) Termination Deposit.  Carso shall deliver at Closing to each
              -------------------                                         
Seller the sum of $500,000 (collectively, the "Termination Deposit"), which
shall be held by Sellers, subject to the provisions of this Section 2, as
collateral security for the obligations of PSC set forth in Section 2(a) above
and Section 2(d) below.  PSC shall be entitled to return of the Termination
Deposit upon termination of the Lease on or prior to December 31, 1997 in
accordance with its terms and after 
<PAGE>
 
satisfaction (including but not limited to timely vacating the premises covered
by the Lease on or prior to December 31, 1997) of all of PSC's obligations under
the Lease ("Lease Termination"). PSC shall, as a condition precedent to its
right to return of the Termination Deposit based on Lease Termination, deliver
to Sellers a certificate, addressed to Sellers and signed by the chief financial
officer or chief executive officer of PSC, stating that, as of the date of such
certificate, PSC has (i) timely vacated the premises covered by the Lease as of
a date on or prior to December 31, 1997, (ii) timely performed all of its
obligations under the Lease and is not in default under the Lease, and (iii)
timely complied with all of the provisions of the Lease required to terminate,
and has terminated, the Lease as of a date on or prior to December 31, 1997.

          (c) Investment of Termination Deposit.  The Termination Deposit shall
              ---------------------------------                                
be invested by each Seller, in its own name, in a segregated, interest-bearing
bank money market account, mutual fund money market account or other form of
investment customarily used by such Seller for its own short-term cash
investments.  Interest earned thereon shall be added to and become part of the
Termination Deposit.

          (d) Indemnification.  If Lease Termination does not occur on or prior
              ---------------                                                  
to December 31, 1997, PSC shall indemnify and hold harmless each Seller from and
against all liabilities of whatsoever kind that such Seller may have to Landlord
under or in connection with the Lease, and pay and reimburse each Seller for its
costs and expenses (including reasonable attorneys' fees) incurred by such
Seller in respect of any claim made by the Landlord against Sellers, or either
of them, under or in connection with the Lease.  PSC hereby grants each Seller a
senior lien and security interest in the Termination Deposit to secure
satisfaction of PSC's obligations set forth herein.  Sellers shall be entitled
to apply the Termination Deposit to satisfy PSC's obligations as set forth
herein, which shall include, but not be limited to, the right to apply the
Termination Deposit to reimburse themselves for any sums that they have paid the
Landlord in respect of the Lease, whether paid pursuant to a judgment entered
against either Seller, a settlement with the Landlord, or otherwise.

     3.   Closing Conditions.  The closing (the "Closing") of the transactions
          ------------------                                                  
contemplated hereby shall occur as soon as possible after satisfaction of the
conditions set forth in this Section 3.  If the conditions specified in this
Section 3 have not been satisfied by October 31, 1997, the Closing shall not
occur and this Agreement shall automatically terminate with no liability of any
party hereunder to any other party hereunder.  If this Agreement terminates as
provided in the preceding sentence, the Old Notes shall not be modified and
shall continue in accordance with their terms.  The conditions to Closing are as
follows:

          (a) Lease Arrangements.  Carso shall have fully paid the Lease Amount
              ------------------                                               
to the Landlord and delivered to Sellers evidence reasonably satisfactory to
Sellers that the Lease Amount has been fully paid to the Landlord.  Carso shall
have delivered the Termination Deposit to the Sellers.

          (b) Letter of Credit Arrangements.  Carso shall have caused the
              -----------------------------                              
execution and delivery to Sellers at Closing of a clean irrevocable letter of
credit issued or confirmed by a domestic bank in the United States or a branch
of a foreign bank, which branch is located in the United States, in each case
acceptable to Sellers (the "Carso LC").  The Carso LC shall be in form and
substance mutually agreed to by Sellers and Carso and shall be in the initial
face amount of $4,000,000 (with the face amount declining at the end of each
subsequent calendar quarter to an amount equal to $4,000,000 minus the greater
of (i) $333,333.33 multiplied by the number of full calendar quarters elapsed
since the Closing or (ii) the aggregate amount of all draws against the Carso LC
since the Closing).  The Carso LC shall secure, and may be drawn against only
with respect to, the obligation of the Company under Section 10.2 of the
Purchase Agreement to indemnify Sellers against Covered Damages. "Covered
Damages" shall mean Damages (as defined in Section 10.2 of the Purchase
Agreement) arising from claims by third parties (i.e., parties other than either
Seller or any entity controlled by or 

                                      -2-
<PAGE>
 
affiliated with either Seller); provided, however, that Covered Damages shall
                                --------  -------
include Damages arising from claims for taxes (as defined in Section 9.5 of the
Purchase Agreement) of Old Prodigy for Pre-Closing Taxable Periods (as defined
in Section 9.5 of the Purchase Agreement) only to the extent that PSC does not
comply with its obligations under Section 9 below. The Carso LC shall be subject
to multiple draws, in each case upon presentation, at any time prior to
September 30, 2000, of a sight draft purporting to be signed by an officer of
either Seller accompanied by a certificate signed by an officer of the drawer,
in form and substance mutually agreed to by Sellers and Carso, stating that the
drawer has incurred Covered Damages for which the drawer is entitled to be
indemnified under Section 10.2 of the Purchase Agreement. Carso shall have the
right to control the defense and settlement (with counsel of its choosing
reasonably acceptable to Sellers) of all claims which may give rise to Covered
Damages and, if it does not do so within a reasonable period of time after being
notified of any such claims, Sellers shall be entitled to retain counsel of
their choosing (and reasonably acceptable to Carso) to provide such defense (in
which case the reasonable fees and expenses of one firm of outside counsel to
represent Sellers with respect to such claims shall also constitute Covered
Damages).

          (c)  Additional Agreements Regarding the Carso LC.  The Company hereby
               --------------------------------------------                     
agrees that (i) any obligation to reimburse the issuing bank, Carso or any other
party in respect of draws on the Carso LC shall not be secured by any assets of
a "Prodigy Entity" (as defined below) and shall not give rise to a claim against
a Prodigy Entity that does not have liability for Covered Damages under the
Purchase Agreement or give rise to a claim against a Prodigy Entity senior in
priority to the Sellers' claim for Covered Damages under the Purchase Agreement
(such prohibitions being hereinafter referred to as the "Prohibited
Attributes"); and (ii) in the event the Carso LC is determined to possess
Prohibited Attributes, or if a stay, restraining order or injunction is in
effect that prevents either Seller from drawing on the Carso LC based in whole
or in part upon an allegation that the Carso LC possesses Prohibited Attributes,
then Carso shall provide a substitute Carso LC that does not possess Prohibited
Attributes.  The documentation and arrangements respecting the Carso LC shall be
made available to Sellers for review prior to Closing and shall establish to
their satisfaction that the Carso LC does not possess Prohibited Attributes.  As
used herein, the term "Prodigy Entity" means and includes the Company and any
direct or indirect subsidiary of the Company, including but not limited to PSC.

     4.   The Closing.  At the Closing:
          -----------                  

          (a)  PSC shall execute and deliver a New Note to each Seller.

          (b)  PSC shall execute and deliver a Warrant to each Seller.

          (c)  Each Seller shall return to the Company its Old Note, marked
"cancelled".

          (d)  Carso shall deliver the Termination Deposit to the Sellers.

          (e)  Carso shall make the payments to the Sellers contemplated by
Section 9.

     5.   Representations of the Sellers.  Each Seller hereby represents and
          ------------------------------                                    
warrants as follows as to itself:

          (a)  Authorization.  Seller has all necessary right, power and
               -------------                                            
authority to enter into this Agreement. The execution, delivery and performance
by Seller of this Agreement has been duly authorized by all requisite corporate
action on the part of Seller. This Agreement constitutes the valid and legally
binding obligation of Seller, enforceable against Seller in accordance with its
terms.

                                      -3-
<PAGE>
 
          (b)  Certain Tax Payments.  Each Seller paid the State of New York
               --------------------                                         
$1,107,764 in January 1997 and $588,045 in October 1997 in respect of certain
sales and use taxes assessed against Old Prodigy for periods ending prior to
June 17, 1996.  Each Seller also paid, after June 17, 1996, $4,796.50 to the
State of Illinois in respect of certain sales and use taxes assessed against Old
Prodigy for periods ending prior to June 17, 1996.

          (c)  Securities Representations.  Seller has substantial knowledge and
               --------------------------                                       
experience in making investment decisions of the type contemplated by the
exchange of an Old Note for a New Note and Warrant and is capable of evaluating
the merits and risks of such exchange.  Seller has received and reviewed the
Company's Confidential Private Placement Memorandum dated October 31, 1997
(draft dated October 16, 1997) (the "Memorandum").  The Company has made
available to Seller all documents requested and has provided answers to all of
its questions relating to an investment in the Company or PSC.  In evaluating
the exchange of its Old Note for a New Note and Warrant, Seller has not relied
upon any representations or other information (whether oral or written) other
than as set forth in the Memorandum.  Seller has had an opportunity to discuss
such exchange with representatives of the Company and to ask questions of them.
Seller understands that an investment in the Company or PSC involves significant
risks, and Seller has reviewed and is aware of the risk factors described in the
Memorandum under the caption "Risk Factors".  Seller is acquiring its New Note
and Warrant, the Common Stock (as defined in the New Notes) issuable upon
conversion of its New Note and the Common Stock (or other securities) issuable
upon exercise of its Warrant (collectively, the "Securities") for its own
account for investment, not for resale to any other person and not with a view
to or in connection with any resale or distribution.  Seller understands that
the Securities have not been registered under the federal securities laws or the
securities laws of any other jurisdiction and cannot be transferred or resold
except as permitted pursuant to a valid registration statement or an applicable
exemption from registration.  Seller acknowledges that neither the Company nor
PSC has made any representations with respect to registration of the Securities
under applicable securities laws (except as provided in Section 5 of the New
Notes), that no such registration is contemplated, that there can be no
assurance that there will be any market for the Securities in the foreseeable
future and that, as a result, Seller must be prepared to bear the economic risk
of its investment for an indefinite period of time.  Seller understands that the
certificates or other instruments representing the Securities shall bear
restrictive legends under the Securities Act of 1933. Seller acknowledges that
no representations have been made to it concerning the size, valuation or timing
of an initial public offering or other financing by the Company or PSC.

     6.   Representations of the Company.  The Company hereby represents and
          ------------------------------                                    
warrants as follows to the Sellers.  The Company has all necessary right, power
and authority to enter into this Agreement.  The execution, delivery and
performance by the Company of this Agreement has been duly authorized by all
requisite corporate action on the part of the Company.  This Agreement
constitutes the valid and legally binding obligation of the Company, enforceable
against the Company in accordance with its terms.

     7.   Representations of PSC.  PSC hereby represents and warrants as follows
          ----------------------                                                
to the Sellers:

          (a)  Authorization by PSC.  PSC has all necessary right, power and
               --------------------                                         
authority to enter into this Agreement.  The execution, delivery and performance
by PSC of this Agreement has been duly authorized by all requisite corporate
action on the part of PSC.  This Agreement constitutes the valid and legally
binding obligation of PSC, enforceable against PSC in accordance with its terms.

          (b)  PSC's Issuance of Securities.  Prior to the Closing, the issuance
               ----------------------------                                     
and delivery of the New Notes in accordance with this Agreement, the issuance
and delivery of the Warrants in accordance with this Agreement, the issuance and
delivery of the shares of Common Stock 

                                      -4-
<PAGE>
 
issuable upon conversion of the New Notes and the issuance and delivery of the
shares of Common Stock issuable by PSC upon exercise of the Warrants will be
duly authorized by all necessary corporate action on the part of PSC, and all
such shares will be duly reserved for issuance. The shares of Common Stock
issuable upon conversion of the New Notes, when so issued in accordance with the
provisions of the New Notes, and the shares of Common Stock issuable by PSC upon
exercise of the Warrants, when so issued against payment therefor in accordance
with the Warrants, will be duly and validly issued, fully paid and non-
assessable.

          (c)  Enforceablility.  Upon their issuance as contemplated hereby, the
               ---------------                                                  
New Notes and Warrants will constitute the valid and legally binding obligations
of PSC, enforceable against PSC in accordance with their respective terms,
subject to applicable bankruptcy, insolvency, reorganization or similar laws
affecting generally the enforcement of creditors' rights and subject to a
court's discretionary authority with respect to the granting of a decree
ordering specific performance or other equitable remedies.

     8.   Representations of the Company and PSC.  The Company and PSC hereby
          --------------------------------------

          (b)  The Carso Funds shall be reimbursed to Carso only from the

Company as described in the following sentence, and PSC shall be released from

Notes and Warrants, provision shall be made so that the Sellers shall be
entitled to receive, upon conversion of the New Notes and exercise of the
Warrants, shares of stock or other securities or property of the Acquiror as
described in the following sentence, and PSC shall be released from the New
Notes and Warrants.  Upon a Company Acquisition, the Sellers shall be entitled
to receive upon conversion of the New Notes and exercise of the Warrants shares
of stock or other securities or property of the Acquiror based on the ratio of
the Fair Market Value of PSC divided by the Fair Market Value of the Company (on
a consolidated basis) immediately prior to the Company Acquisition.  "Acquiror"
shall mean the Company or other entity, as applicable, surviving the Company
Acquisition.

annum on the unpaid principal amount of this Note outstanding, beginning on
December 17, 1997.  The Company may pay all accrued and unpaid interest
quarterly in arrears on June 30, September 30, December 31 and March 31,
commencing on December 31, 1997; provided, that whenever any payment of interest
                                 --------                                       
shall be due on a day which is not a business day, the date for payment thereof
shall be extended to the next succeeding business day.  Interest that is due
but, at the option of the Company, not paid at any payment date shall be added
to the principal amount of this Note, and thereafter interest shall 

                                      -3-
<PAGE>
 
accrue on a quarterly basis at the annual rate set forth above on such increased
principal amount until maturity or repayment.

          2.2  Net Worth Contingency.  Notwithstanding any other provision of
               ---------------------                                         
this Note, payments of principal, or at the Company's election, payments of
interest in cash, on this Note shall be made (and Common Stock shall be issuable
upon conversion of this Note) only if, and to the extent that, a payment of cash
of equal amount (or of equal amount to the then fair market value of such Common
Stock) by the Company would not, as of the date of payment, cause the Net Worth
(as defined below) of the Company to be less than $15,000,000.  For purposes of
this provision, the term "Net Worth" shall mean the excess of the fair market
value of the assets of the Company (on a going concern basis or a liquidation
basis, whichever is greater, as determined by a mutually acceptable nationally
recognized investment bank or valuation expert chosen by the Company) over the
principal amount of the liabilities (other than this Note and the 8% Contingent
Convertible Promissory Note of like tenor issued to ___________________) of the
Company as of the date of payment.

     SECTION 3.  Events of Default.  The following events (if any occur prior to
                 -----------------                                              
the date this Note is paid in full) are "EVENTS OF DEFAULT" under this Note:

          (a)  The Company shall default in the due and punctual payment of

          (e)  Any order, judgment or decree shall be entered against the
Company or any of its subsidiaries decreeing the dissolution or split up of the
Company or any such subsidiary and such order shall remain unstayed or
undischarged for a period in excess of 60 days.

     The occurrence of any of the Events of Default set forth in Sections 3(c),
3(d) or 3(e) of this Note shall automatically make due and payable the
Contingent Payment Amount without notice, presentment, demand, protest or other
requirement of any kind, all of which are expressly hereby waived.  Upon the
occurrence of any other Event of Default set forth above, the Noteholder may, by
written notice to the Company, declare that either the Contingent Acquisition
Payment Amount or the Contingent IPO Payment Amount, as applicable, is
immediately due and payable.

     SECTION 4.  Conversion.
                 ---------- 

          4.1  Conversion.  Upon the earliest to occur of (i) an IPO, (ii) an
               ----------                                                    
Acquisition Transaction or (iii) the Maturity Date (each, a "Conversion Event"),
this Note, including all accrued and unpaid interest hereon, shall be converted
into the following:  (w) in the case of an IPO, the Contingent IPO Payment
Amount, (x) in the case of an Acquisition Transaction, the Contingent
Acquisition Payment Amount, and (y) in the case of the Maturity Date, such
number of shares of Common Stock equal to seven and one-half percent (7.5%) of
the number of shares of Common Stock outstanding on the Maturity Date; provided,
                                                                       -------- 
however, that at the option of the Company, in the case of an IPO or at the
- -------                                                                    
Maturity Date, the Company may redeem this Note for cash in an amount equal to
the value of the Maximum Security Return.  Upon the occurrence of a Conversion
Event:

               (a) the Company will deliver to the Noteholder the appropriate
Contingent Payment Amount; and

               (b) simultaneously with the delivery described in Section 4.1(a),
the Noteholder will deliver to the Company this Note which will he cancelled and
deemed paid in full upon delivery to the Noteholder of the Contingent Conversion
Payment.

     Five business days prior to the anticipated pricing date of an IPO or the
anticipated closing date of an Acquisition Transaction, the Company shall give
the Noteholder written notice thereof.

          4.2  Adjustments for Non-Stock Dividends and Distributions.  In the
               -----------------------------------------------------         
event that, after the date of this Note and prior to a Conversion Event, the
Company shall at any time or from time to time make or issue to holders of
Common Stock, or fix a record date for the determination of holders of Common
Stock entitled to receive, a dividend or other distribution payable other than
in securities of the Company that would be considered as outstanding for
purposes of calculating the Contingent Payment Amount, then and in each such
event provision shall he made so that the Noteholder shall receive upon a
Conversion Event in which it does not otherwise receive the Maximum Security
Return, in addition to the amounts otherwise payable upon such Conversion Event,
7.5% of the aggregate amount of all such dividends and distributions so
distributed to holders of Common Stock, payable, at the option of the Company,
in the form of such dividends or distributions of Common Stock having an
equivalent value (or such lesser amounts as shall, together with the amounts
otherwise received upon such Conversion Event, equal the Maximum Security
Return).

     SECTION 5.  Registration Rights.
                 ------------------- 

          5.1  Piggyback Registration
               ----------------------

                                      -5-
<PAGE>
 
               (a)  Participation - IPO.  If the Company elects to file a
                    -------------------
registration statement under the Securities Act covering the offer and sale by
any of its security holders of any Common Stock in connection with the IPO, the
Company shall give written notice thereof to the Noteholder at least ten
business days before filing. The Noteholder shall have the right (a "PIGGYBACK
REGISTRATION RIGHT") to participate in the IPO on a pro rata basis with any
other Holders entitled to participate in such offering upon the giving of notice
to the Company within ten business days of receipt by it of notice from the
Company. If the Noteholder notifies the Company of its intent to exercise such
Piggyback Registration Right, the Company shall include in such registration
statement such number of shares of Registrable Securities equal to the same
percentage of the total number of Registrable Securities issuable upon the
Conversion Event (with the calculation of the number of Registrable Securities
issuable upon conversion of this Note to be based on the mid-point of the
estimated public offering price set forth in the registration statement (or most
recent amendment thereto) for the IPO) as the number of shares of the other
Holders' Common Stock to be registered bears to such other Holders' aggregate
ownership of Common Stock. Such Registrable Securities shall be included in the
underwriting for the IPO on the same terms and conditions as the securities
otherwise being sold in such offering.

               (b)  Participation - Other Offerings.  If the Company elects to
                    -------------------------------
file a registration statement under the Securities Act covering the offer and
sale of any Common Stock (or equity securities converted into Common Stock) in
connection with any public offering after the IPO (other than a registration
statement on Form S-8 or Form S-4, or their successors, or any other form for a
similar limited purpose, or any registration statement covering only securities
proposed to be issued in exchange for securities or assets of another
corporation), the Company shall give written notice thereof to the Noteholder at
least ten business days before filing. The Noteholder shall have a Piggyback
Registration Right to participate in such offering on a pro rata basis with the
Company and any other Holders upon the giving of notice to the Company within
seven business days of receipt by it of notice from the Company. If the
Noteholder notifies the Company of its intent to exercise such Piggyback
Registration Right, subject to Section 5.1(c), the Company shall include in such
registration statement such number of shares of Restricted Stock equal to the
percentage of the total number of Restricted Shares held by the Noteholder
multiplied by the number of shares proposed to be registered in the offering.
Such Restricted Stock shall be included in the underwriting for the public
offering on the same terms and conditions as the securities otherwise being sold
in such offering.

               (c)  Underwriter's Cutback.  If, in the opinion of the managing
                    ---------------------                                     
underwriter of such offering the inclusion of all of the shares of Registrable
Securities and other Common Stock requested to be registered would be
inappropriate, then the number of shares of Registrable Securities and other
Common Stock to be included in the offering shall be reduced, with the
participation in such offering to be in the following order of priority:  (1)
first, securities to be issued by the Company shall be included, and (2) second,
any other Common Stock required to be included pursuant to any demand
registration right granted to such other Holder of Common Stock shall be
included, and (3) third Registrable Securities and any other Common Stock
requested to be included, on a pro rata basis, shall be included.

               (d)  Lockup Arrangements.  With respect to an IPO, the Noteholder
                    -------------------                                         
agrees that with respect to all shares of Common Stock received by it upon
conversion in connection with an IPO (other than any shares included as part of
the IPO pursuant to Section 5.1(a) hereof), it will agree to withhold such
shares from the market for a period (which shall in no event exceed 270 days)
that the managing underwriter reasonably determines is necessary in order to
effect the IPO (the "LOCKUP ARRANGEMENT"), provided that substantially all other
Holders of five percent (5%) or more of the Common Stock are subject to similar
Lockup Arrangements.  The Noteholder agrees to enter into similar arrangements
on similar conditions with respect to registrations other than the IPO, provided
                                                                        --------
that the lockup period with respect thereto shall not exceed 180 days.

<PAGE>
 
               (e)  Registrant Controls.  The Company may decline to file a
                    -------------------                                    
Registration Statement after giving notice to any Holder pursuant to Sections
5.1(a) or 5.1(b) above, or withdraw a Registration Statement after filing and
after such notice, but prior to the effectiveness thereof, provided that such
registrant shall promptly notify each Holder of Restricted Stock in writing of
any such action and provided further that such registrant shall hear all
reasonable expenses incurred by such Holder of Restricted Stock or otherwise in
connection with such withdrawn Registration Statement.

               (f)  Underwriting Agreement.  In connection with any registration
                    ----------------------
under this Section 5.1 involving an underwriting, the Company shall not be
required to include any Registrable Shares in such registration unless the
Noteholder accepts the terms of the underwriting as determined by the
underwriters selected by the Company after negotiations with the Noteholder
(provided that such terms must be consistent with this Agreement and provided,
further, that any inability of the Noteholder to agree with the underwriters
shall not restrict the ability of the Company to proceed with the registration).

          5.2  Demand Registrations
               --------------------

               (a)  Company's Right of First Offer.  Prior to the Noteholder's
                    ------------------------------                            
exercise of any Demand Registration right hereunder, the Noteholder shall offer
the Restricted Stock to be included in such Demand Registration for sale to the
Company, at a price equal to the average closing price of the Common Stock on
the principal exchange on which the Common Stock is traded during the ten
consecutive trading days immediately prior to the date of such offer.  The
Company shall notify the Noteholder whether it accepts such offer with respect
to all (but not less than all) of such shares within fourteen (14) days of
receipt of notice thereof, and purchase such shares by delivery of immediately
available funds to the Noteholder against delivery of such shares within thirty
(30) days of acceptance thereof.  In the event that the Company declines to
purchase all of the Restricted Stock that is the subject of such offer, the
Noteholder may commence a Demand Registration with respect to all such shares as
set forth below.

               (b)  In General.  Following the occurrence of any Conversion
                    ----------
Event and the expiration of any applicable lockup period, the Noteholder may
request by written notice to the Company that the Company file one or more
Registration Statements under the Securities Act covering the Registrable
Securities issued to the Noteholder as a result of such Conversion Event.

               (c)  Number of Demand Registrations.  Subject to the following
                    ------------------------------                           
sentences, the Company shall be obligated to prepare, file and use its best
efforts to cause a Registration Statement to become effective in connection with
each Demand Registration requested pursuant to Section 5.2(b), and to remain
effective for a period of ninety days or until the sale of all securities
registered thereunder.  If (i) the Company withdraws a Registration Statement
filed pursuant to a Demand Registration prior to the effectiveness thereof, or
(ii) the sale of securities to which a Registration Statement filed pursuant to
a Demand Registration applies is not consummated other than by action of the
Selling Holder, such Registration Statement shall not be counted in determining
the number of registrations in which Noteholder's securities have been included
or otherwise adversely affect Noteholder's rights hereunder.  Subject to the
preceding sentence, the Noteholder may request registration pursuant to Section
5.2(b) on two occasions.

               (d)  No Piggyback Registrations.  The Company and other Holders
                    --------------------------
of Common Stock of the Company may include such securities in such Registration
if, but only if, the managing underwriter concludes that such inclusion will not
interfere with the successful marketing of all the Restricted Stock requested to
be included in such registration.

                                      -7-
<PAGE>
 
               (e)  Managing Underwriter.  The managing underwriter or
                    --------------------
underwriters of any underwritten public offering covered by a Demand
Registration shall be selected by the Holders of a majority of the shares of
Restricted Stock that participate in such registration, subject to the approval
of the Board of Directors of the Company (the "BOARD"), which shall not be
unreasonably withheld.

               (f)  Company's Right to Defer.  If the Company is requested to
                    ------------------------ 
effect a Demand Registration and the Company furnishes to the Holders of
Restricted Stock requesting such registration a copy of a resolution of the
Board certified by the Secretary of the Company stating that in the good faith
judgment of the Board it would be seriously detrimental to the Company and its
stockholders for such registration statement to be filed on or before the date
such filing would otherwise be required hereunder and stating the basis of such
good faith judgment, the Company shall have the right to defer such filing for a
period of not more than 90 days after receipt of the request for such
registration from the Holder or Holders of Restricted Stock requesting such
registration; provided that during such time the Company may not file a
registration statement (other than a registration statement on Form S-4 or Form
S-8 or a registration statement already approved by the Board) for securities to
be issued and sold for its own account or that of anyone other than the Holder
or Holders of Restricted Stock requesting such registration.

          5.3  Indemnification
               ---------------

               (a)  Indemnification by the Company.  The Company agrees to
                    ------------------------------ 
indemnify and hold harmless any Holder of Restricted Stock which has included
Registrable Securities in a registration statement, its officers, directors and
agents and each Person, if any, who controls such Holder within the meaning of
Section 15 of the Securities Act or Section 20 of the Securities Exchange Act of
1934, as amended (the "EXCHANGE ACT"), from and against any and all losses,
claims, damages, liabilities and expenses (including reasonable costs of
investigation) arising out of or based upon any untrue statement or alleged
untrue statement of a material fact contained in any registration statement or
prospectus relating to the Registrable Securities or in any amendment or
supplement thereto or in any preliminary prospectus, or arising out of or based
upon any omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
except insofar as such losses, claims, damages, liabilities or expenses arise
out of, or are based upon, any such untrue statement or omission based upon
information furnished in writing to Company by the Holder of the Registrable
Securities or on such Holder's behalf expressly for use therein; provided, that
                                                                 -------- 
with respect to any untrue statement or omission made in any preliminary
prospectus, the indemnity agreement contained in this paragraph shall not apply
to the extent that any such loss, claim, damage, liability or expense results
from the fact that a current copy of the prospectus was not sent or given to the
person asserting any such loss, claim, damage, liability or expense at or prior
to the written confirmation of the sale of the Registrable Securities concerned
if it is determined that it was the responsibility of the Holder of such
Registrable Securities to provide such person with a current copy of the
prospectus and such current copy of the prospectus would have cured the defect
giving rise to such loss, claim, damage, liability or expense. The Company also
agrees to indemnify any underwriters of the Registrable Securities, their
officers and directors and each person who controls such underwriters on
substantially the same basis as that of the indemnification of the Holder of
such Registrable Securities provided in this Section 5.3.

               (b)  Indemnification by the Holder of Restricted Stock.  The
                    -------------------------------------------------
Holder of Restricted Stock, to the extent it is selling Registrable Securities
("SELLING HOLDER"), agrees to indemnify and hold harmless the Company, its
directors and officers and each Person, if any, who controls the Company within
the meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act to the same extent as the foregoing indemnity from the Company to
the Selling Holder, but only with respect to information furnished in writing by
the Selling Holder or on the Selling

                                      -8-
<PAGE>
 
Holder's behalf expressly for use in any Registration Statement or Prospectus
relating to the Registrable Securities which contained a material misstatement
of fact or omission of material fact, or any amendment or supplement thereto, or
any preliminary prospectus. In case any action or proceeding shall be brought
against the Company or its directors or officers, or any such controlling
Person, in respect of which indemnity may be sought against such Selling Holder,
such Selling Holder shall have the rights and duties given to the Company, and
the Company or its directors or officers or such controlling Person shall have
the rights and duties given to such Selling Holder, by the preceding subsection.

     The Selling Holder also agrees to indemnify and hold harmless the
underwriters on substantially the same basis of that of the indemnification of
the Company provided in the preceding subsection.

          5.4  Contribution.  If the indemnification provided for in Section 5.3
               ------------                                                     
hereof is unavailable to the Company, the Selling Holder or the underwriters in
respect of any losses, claims, damages, liabilities, expenses or judgments
referred to herein, then each such indemnifying party, in lieu of indemnifying
such indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages, liabilities,
expenses and judgments (i) as between the Company and the Selling Holder on the
one hand and the underwriters on the other, in such proportion as is appropriate
to reflect the relative benefits received by the Company and the Selling Holder
on the one hand and the underwriters on the other from the offering of the
Registrable Securities, or if such allocation is not permitted by applicable
law, in such proportion as is appropriate to reflect not only such relative
benefits but also the relative fault of the Company and the Selling Holder on
the one hand and of the underwriters on the other in connection with the
statements or omissions which resulted in such losses, claims, damages,
liabilities, expenses or judgments, as well as any other relevant equitable
considerations and (ii) as between the Company on the one hand and each Selling
Holder on the other, in such proportion as is appropriate to reflect the
relative fault of the Company and of each Selling Holder in connection with such
statements or omissions, as well as any other relevant equitable considerations.
The relative benefits received by the Company and the Selling Holder on the one
hand and the underwriters on the other shall be deemed to be in the same
proportion as the total proceeds from the offering (net of underwriting
discounts and commissions but before deducting expenses) received by the Company
and the Selling Holder bear to the total underwriting discounts and commissions
received by the underwriters, in each case as set forth in the table on the
cover page of the prospectus.  The relative fault of the Company on the one hand
and of each Selling Holder on the other shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to
information supplied by such party, and the party's relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission.

     The Company and the Noteholder agree that it would not be just and
equitable if contribution pursuant to this Section 5.4 were determined by pro
rata allocation or by any other method of allocation which does not take account
of the equitable considerations referred to in the immediately preceding
paragraph.  The amount paid or payable by an indemnified party as a result of
the losses, claims, damages, liabilities, expenses or judgments referred to in
the immediately preceding paragraph shall be deemed to include, subject to the
limitations set forth above, any legal or other expenses reasonably incurred by
such indemnified party in connection with investigating or defending any such
action or claim.  Notwithstanding the provisions of this Section 5.4, no
underwriter shall be required to contribute any amount in excess of the amount
by which the total price at which the Registrable Securities underwritten by it
and distributed to the public were offered to the public exceeds the amount of
any damages which such underwriter has otherwise been required to pay by reason
of such untrue or alleged untrue statement or omission or alleged omission, and
no Selling Holder shall be required to contribute any amount in excess of the
amount by which the total price at which the 

                                      -9-
<PAGE>
 
Registrable Securities of such Selling Holder were offered to the public exceeds
the amount of any damages which such Selling Holder has otherwise been required
to pay by reason of such untrue or alleged untrue statement or omission or
alleged omission. No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall he entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.

          5.5  Termination.  The Noteholder's registration rights under this
               -----------                                                  
Section 5 shall terminate at such time as the Noteholder is permitted to sell
all shares of Restricted Stock held by it pursuant to the provisions of Rule 144
promulgated under the Securities Act during any three month period, provided
that at such time the restrictions set forth in Section 9.2 hereof are not
applicable or, if applicable, have been waived by the Company.

     SECTION 6.  Registration Expenses.
                 --------------------- 

          (a)  Demand Registrations.  The Company shall bear all Registration
               --------------------                                          
Expenses incurred in connection with two Demand Registrations requested by the
Noteholder.

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

reorganization of the Common Stock or a merger or consolidation of the Company
with and into another corporation, or the sale of all or substantially all the
Company's properties and assets or capital stock to any other Person that does
not constitute an Acquisition Transaction, then, as a part of such
reorganization, merger, consolidation or sale, provision shall be made so that
the Noteholder shall thereafter be entitled to receive, upon conversion of this
Note, the number of shares of stock or other securities or property of the
Company, or of the successor corporation resulting from such merger or
consolidation or sale, to which it is entitled hereunder.  In any such case,
appropriate adjustment shall be made in the application of the provisions of
this Section 7 with respect to the rights of the Noteholder after the
reorganization, merger, consolidation or sale to the end that the provisions of
this Section 7 (including adjustment of the number of shares to be received by
the Noteholder upon any Conversion Event) shall be applicable after that event
as nearly equivalent as is possible.

     SECTION 8.  Voting Rights.  Prior to any Conversion Event, this Note shall

stockholder of the Company.  Subject to the conditions set forth in the last
sentence of this Section 8, upon any conversion of this Note into Common Stock,

rights) to which Holders of Common Stock are entitled.  Notwithstanding the
foregoing, after the receipt by the Noteholder of Common Stock pursuant to a
Conversion Event, the Noteholder agrees to vote its shares of Common Stock in
accordance with the voting recommendations of the Board and such agreement,
subject to the proviso below, shall be binding upon any transferee of this Note
or the shares of Common Stock obtained on conversion hereof; provided, however,
                                                             --------  ------- 
that if the Noteholder transfers this Note or shares of Common Stock obtained
upon any conversion hereof to any person who, together with any Related Party,
owns less than five percent (5%) of the outstanding Common 

                                     -10-

                 --------- 

          9.1  Related Party Transactions.  The Company shall not, and shall not

enter into, amend or make any contract, agreement, understanding, loan, advance
or guarantee with, or for the benefit of, any Related Party involving the
payment or receipt of more than $10,000 in any such instance (each of the
foregoing, a "Related Party Transaction"), unless the Company's Board of
Directors has determined that such Related Party Transaction is on terms that
are no less favorable to the Company or the relevant subsidiary than those that
would be obtained in a comparable transaction with an unrelated Person.

          9.2  Selling Restrictions.  Other than sales pursuant to a
               --------------------                                 
registration statement filed under Section 5, the Noteholder agrees that it
shall not sell any Restricted Securities unless such sales would comply with the
volume limitations of paragraph (e)(1) of Rule 144 promulgated under the
Securities Act (as currently in effect), regardless of whether such limitations
would apply under the terms of such rule.

     SECTION 10. Acquisition or IPO by Subsidiary.
                  -------------------------------- 

          10.1 IPO by Subsidiary.  If, prior to an IPO, the Company transfers

all or substantially all of its assets to any direct or indirect wholly owned
subsidiary (a "Subsidiary") and the Subsidiary subsequently undertakes a
transaction which would constitute an IPO (a "Subsidiary IPO") if undertaken by
the Company, then, simultaneously with and as a condition to the Subsidiary IPO,
the Subsidiary shall assume this Note, provision shall be made so that the
Noteholder shall be entitled to receive, upon conversion of this Note, shares of
stock or other securities or property of the Subsidiary to which it is entitled
under this Note, and the Company shall be released from this Note.

          10.2 Acquisition of Subsidiary.  If, prior to an Acquisition
               -------------------------                              
Transaction, the Company transfers all or substantially all of its assets to a
Subsidiary and the Subsidiary subsequently undertakes a transaction which would
constitute an Acquisition Transaction (a "Subsidiary Acquisition") if undertaken
by the Company, then, simultaneously with and as a condition to the Subsidiary
Acquisition, the Acquiror (as defined below) shall assume this Note, provision
shall be made so that the Noteholder shall be entitled to receive, upon
conversion of this Note, shares of stock or other securities or property of the
Acquiror to which it is entitled under this Note, and the Company shall be
released from this Note.  "Acquiror" shall mean the Subsidiary or other entity,
as applicable, surviving the Subsidiary Acquisition.

               -------------------                                           
that (a) Section 2.2 hereof shall render all payments under this Note
"contingent" for purposes of Sections 1272-1276 of the Internal Revenue Code of
1986, as amended, and the applicable Treasury Regulations thereunder, (b) the
contingencies applicable to all such payments are neither remote nor incidental
under Treas. Reg. (S) 1.1275-4(a)(5) and (c) all such contingent payments under
this Note shall be subject to recharacterization as principal and interest in
accordance with Treas. Reg. (S) 1.1275-4(c)(4) using the "test rate" specified
in Treas. Reg. (S) 1.1275-4(c)(4)(ii)(B).

the Noteholder would otherwise be 

                                     -11-

entitled, the Company shall pay cash equal to the product of such fraction
multiplied by the fair market value of one share of Common Stock on the date of
conversion, as reasonably determined in good faith by the Board. Whether or not
fractional shares are issuable upon such conversion shall be determined on the
basis of the total number of shares of Common Stock issuable upon such
conversion.

          11.3 Reservation of Stock Issuable Upon Conversion.  The Company shall
               ---------------------------------------------

shares of Common Stock, solely for the following purposes, (i) such number of
shares of Common Stock required to pay all dividends payable in Common Stock
which the Company by agreement is obligated, or may choose to pay, (ii) such
number of shares of Common Stock as may from time to time be required, at such
time, to be issued by the Company upon exercise of all then-exercisable warrants
and options to purchase Common Stock or the right to convert other convertible
securities into Common Stock, and (iii) such number of its shares of Common
Stock as the Board in good faith determines shall from time to time be
sufficient to effect the conversion of all outstanding convertible securities
(including this Note).

          11.4 Securities Law Matters.  THIS NOTE HAS NOT BEEN REGISTERED UNDER
               ----------------------

     FOR VALUE RECEIVED, PRODIGY SERVICES CORPORATION, a Delaware corporation
(the "Company"), hereby grants, subject to the terms set forth below,
____________________________ (the "Holder"), a warrant (this "Warrant") to
purchase the Warrant Shares at the Purchase Price (as such terms are defined
below):

     1.   Certain Definitions.  This Warrant is granted pursuant to that certain
          -------------------

Convertible Promissory Note (the "Note") of even date hereof issued by the
Company to Holder pursuant to the Exchange Agreement. In addition, the following
terms shall have the following meanings:

share, of the Company.

          (b)  "Warrant Shares" shall mean:

               (i)  if this Warrant becomes exercisable by reason of an IPO,
such number of shares of Common Stock as equals (A) seven and one-half percent
(7.5%) of the number of shares of Common Stock outstanding immediately after
such IPO (as shown in the final prospectus for such IPO) less (B) the number of
shares of Common Stock, if any, issued to the Holder upon conversion of the Note
in such IPO; or

               (ii) if this Warrant becomes exercisable by reason of an
Acquisition Transaction, such number of shares of Common Stock as equals (A)
seven and one-half percent (7.5%) of the number of shares of Common Stock
outstanding immediately prior to such Acquisition Transaction less (B) the
number of shares of Common Stock, if any, issued to the Holder upon conversion
of the Note in such Acquisition Transaction.

          (c)  "Market Price" shall mean:

               (i)  if this Warrant becomes exercisable by reason of an IPO, the
price per share at which Common Stock is sold in such IPO; or

               (ii) if this Warrant becomes exercisable by reason of an
Acquisition Transaction, a price per share of Common Stock equal to the fair
market value of the Common Stock immediately prior to the closing of the
Acquisition Transaction.

          (d)  "Purchase Price" shall mean 130% of the Market Price, as adjusted
pursuant to the terms of this Warrant.

     2.   Exercise and Expiration of Warrant.
          ---------------------------------- 

          (a)  This Warrant shall become exercisable upon the closing of the
earlier of an IPO or an Acquisition Transaction and shall remain exercisable for
a period of three years thereafter (the
<PAGE>
 
"Exercise Period"). If neither an IPO nor an Acquisition Transaction occurs
prior to the Maturity Date, this Warrant shall never become exercisable and
shall terminate automatically upon the Maturity Date.

          (b)  This Warrant may be exercised during the Exercise Period by the
Holder, in whole or in part, by surrendering this Warrant at the principal
office of the Company, or at such other office or agency as the Company may
designate, accompanied by payment in full, in lawful money of the United States,
of the Purchase Price payable in respect of the number of Warrant Shares
purchased upon such exercise.

          (c)  Each exercise of this Warrant shall be deemed to have been
effected immediately prior to the close of business on the day on which this
Warrant shall have been surrendered to the Company as provided in Section 2(b)
above.

          (d)  As soon as practicable after the exercise of this Warrant in full
or in part, the Company, at its expense, will cause to be issued in the name of,
and delivered to, the Holder:

               (i)  a certificate or certificates for the number of full Warrant
Shares to which the Holder shall be entitled upon such exercise plus, in lieu of
any fractional share to which the Holder would otherwise be entitled, cash in an
amount determined pursuant to Section 6 hereof; and

               (ii) in case such exercise is in part only, a new warrant or
warrants (dated the date hereof) of like tenor, calling in the aggregate on the
face or faces thereof for the number of Warrant Shares equal (without giving
effect to any adjustment therein) to the number of such shares called for on the
face of this Warrant minus the number of such shares purchased by the Holder
upon such exercise.

     3.   Adjustments.

purchase or otherwise acquire Common Stock or Convertible Securities, excluding
options described in Section 3(b)(i)(D) below.

          (B)  "Conversion Date" shall mean the first day of the Exercise 
                ---------------

          (C)  "Convertible Securities" shall mean any evidences of 
                ----------------------                                        
indebtedness, shares or other securities directly or indirectly convertible into
or exchangeable for Common Stock.

          (D)  "Additional Shares of Common Stock" shall mean all shares of
                ---------------------------------

issued) by the Company after the Conversion Date, other than shares of Common
Stock issued or issuable to employees or directors of, or consultants or
advisors to, the Company pursuant to a plan, agreement or other arrangement

<PAGE>
 
     (ii)  No Adjustment of Purchase Price.  No adjustments to the Purchase 
           -------------------------------                                     
Price shall be made unless the consideration per share (determined pursuant to
Section 3(b)(v)) for an Additional Share of Common Stock issued or deemed to be
issued by the Company is less than the Purchase Price in effect on the date of,
and immediately prior to, the issue of such Additional Shares of Common Stock.

     (iii) Issue of Securities Deemed Issue of Additional Shares of Common
           ---------------------------------------------------------------
Stock.  If the Company at any time or from time to time after the Conversion
- -----                                                                       
Date shall issue any Options or Convertible Securities or shall fix a record
date for the determination of holders of any class of securities entitled to
receive any such Options or Convertible Securities, then the maximum number of
shares of Common Stock (as set forth in the instrument relating thereto without
regard to any provision contained therein for a subsequent adjustment of such
number) issuable upon the exercise of such Options or, in the case of
Convertible Securities and Options therefor, the conversion or exchange of such
Convertible Securities, shall be deemed to be Additional Shares of Common Stock
issued as of the time of such issue or, in case such a record date shall have
been fixed, as of the close of business on such record date, provided that
Additional Shares of Common Stock shall not be deemed to have been issued unless
the consideration per share (determined pursuant to Section 3(b)(v) hereof) of
such Additional Shares of Common Stock would be less than the Purchase Price in
effect on the date of and immediately prior to such issue, or such record date,
as the case may be, and provided further that in any such case in which
Additional Shares of Common Stock are deemed to be issued:

           (A)  No further adjustment in the Purchase Price shall be made upon
the subsequent issue of Convertible Securities or shares of Common Stock upon
the exercise of such Options or conversion or exchange of such Convertible
Securities;

           (B)  If such Options or Convertible Securities by their terms
provide, with the passage of time or otherwise, for any increase in the
consideration payable to the Company, upon the exercise, conversion or exchange
thereof, the Purchase Price computed upon the original issue thereof (or upon
the occurrence of a record date with respect thereto), and any subsequent
adjustments based thereon, shall, upon any such increase becoming effective, be
recomputed to reflect such increase insofar as it affects such Options or the
rights of conversion or exchange under such Convertible Securities;

           (C)  Upon the expiration or termination of any unexercised Option,
the Purchase Price shall not be readjusted, but the Additional Shares of Common
Stock deemed issued as the result of the original issue of such Option shall not
be deemed issued for the purposes of any subsequent adjustment of the Purchase
Price;

           (D)  In the event of any change in the number of shares of Common
Stock issuable upon the exercise, conversion or exchange of any Option or
Convertible Security, including, but not limited to, a change resulting from the
anti-dilution provisions thereof, the Purchase Price then in effect shall
forthwith be readjusted to such Purchase Price as would have obtained had the
adjustment which was made upon the issuance of such Option or Convertible
Security not exercised or converted prior to such change been made upon the
basis of such change; and

           (E)  No readjustment pursuant to Clause (B) or (D) above shall have
the effect of increasing the Purchase Price to an amount which exceeds the lower
of (i) the Purchase Price on the original adjustment date, or (ii) the Purchase
Price that would have resulted from any issuances of Additional Shares of Common
Stock between the original adjustment date and such readjustment date.

     (iv)  Adjustment of Purchase Price Upon Issuance of Additional Shares of
           ------------------------------------------------------------------
Common Stock.  In the event the Company shall at any time after the Conversion

Common Stock (including Additional Shares of Common Stock deemed to be issued
pursuant to Section 3(b)(iii), but excluding shares issued as a dividend or
distribution or upon a stock split or combination as provided in Section 3(c)),
without consideration or for a consideration per share less than the Purchase
Price in effect on the date of and immediately prior to such issue, then and in
such event, such Purchase Price shall be reduced, concurrently with such issue,
to a price (calculated to the nearest cent) determined by multiplying such
Purchase Price by a fraction, (A) the numerator of which shall be (1) the number
of shares of Common Stock outstanding immediately prior to such issue plus (2)
the number of shares of Common Stock which the aggregate consideration received
or to be received by the Company for the total number of Additional Shares of
Common Stock so issued would purchase at such Purchase Price; and (B) the
denominator of which shall be the number of shares of Common Stock outstanding
immediately prior to such issue plus the number of such Additional Shares of
Common Stock so issued; provided that, (i) for the purpose of this Section 
                        -------------     
3(b)(iv), all shares of Common Stock issuable upon exercise or conversion of
Options or Convertible Securities outstanding immediately prior to such issue
shall be deemed to be outstanding (other than shares excluded from the
definition of "Additional Shares of Common Stock" by virtue of Section
3(b)(i)(D)), and (ii) the number of shares of Common Stock deemed issuable upon
conversion of such outstanding Options and Convertible Securities shall not give
effect to any adjustments to the conversion price or conversion rate of such
Options or Convertible Securities resulting from the issuance of Additional
Shares of Common Stock that is the subject of this calculation.

          Notwithstanding the foregoing, the applicable Purchase Price shall not
be so reduced unless the amount of the reduction would reduce the Purchase Price
to less than the Market Price (for this purpose only, as proportionately
adjusted for any stock dividend, stock split, combination or other similar event
affecting the Common Stock after the Conversion Date), but any such amount shall
be carried forward and reduction with respect thereto made at the time of and
together with any subsequent reduction which, together with such amount and any
other amount or amounts so carried forward, shall reduce the Purchase Price to
less than the Market Price (for this purpose only, as proportionately adjusted
for any stock dividend, stock split, combination or other similar event
affecting the Common Stock after the Conversion Date).

     (v)  Determination of Consideration.  For purposes of this Section 3(b), 
          ------------------------------                                        
the consideration received by the Company for the issue of any Additional Shares
of Common Stock shall be computed as follows:

          (A)  Cash and Property:  Such consideration shall:
               -----------------                            

                         (I)   insofar as it consists of cash, be computed at
the aggregate of cash received by the Company, excluding amounts paid or payable
for accrued interest or accrued dividends;

                         (II)  insofar as it consists of property other than
cash, be computed at the fair market value thereof at the time of such issue, as
determined in good faith by the Board of Directors; and

                         (III) in the event Additional Shares of Common Stock
are issued together with other shares or securities or other assets of the
Company for consideration which covers both, be the proportion of such
consideration so received, computed as provided in clauses (I) and (II) above,
as determined in good faith by the Board of Directors.

          (B)  Options and Convertible Securities.  The consideration per share
               ----------------------------------                              
received by the Company for Additional Shares of Common Stock deemed to have
been issued pursuant to Section 3(b)(iii), relating to Options and Convertible
Securities, shall be determined by dividing

                                      -4-
<PAGE>
 
                         (x)  the total amount, if any, received or receivable
by the Company as consideration for the issue of such Options or Convertible
Securities, plus the minimum aggregate amount of additional consideration (as
set forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such consideration) payable to
the Company upon the exercise of such Options or the conversion or exchange of
such Convertible Securities, or in the case of Options for Convertible
Securities, the exercise of such Options for Convertible Securities and the
conversion or exchange of such Convertible Securities, by

                         (y)  the maximum number of shares of Common Stock (as
set forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such number) issuable upon the
exercise of such Options or the conversion or exchange of such Convertible
Securities.

     (vi) Multiple Closing Dates.  In the event the Company shall issue on more
          ----------------------                                               
than one date Additional Shares of Common Stock which are comprised of shares of
the same series or class of capital stock, and such issuance dates occur within
a period of no more than 60 days, then the Purchase Price shall be adjusted only
once on account of such issuances, with such adjustment to occur upon the final
such issuance (but not later than ten days prior to the end of the Exercise
Period) and to give effect to all such issuances as if they occurred on the date
of the final such issuance.

          (c)  Recapitalizations.  If outstanding shares of the Company's Common
               -----------------                                                
Stock shall be subdivided into a greater number of shares or a dividend in
Common Stock shall be paid in respect of Common Stock, the Purchase Price in
effect immediately prior to such subdivision or at the record date of such
dividend shall simultaneously with the effectiveness of such subdivision or
immediately after the record date of such dividend be proportionately reduced.
If outstanding shares of Common Stock shall be combined into a smaller number of
shares, the Purchase Price in effect immediately prior to such combination
shall, simultaneously with the effectiveness of such combination, be
proportionately increased.

          (d)  Mergers, etc.  If there shall occur any capital reorganization or
               ------------                                                     
reclassification of the Company's Common Stock (other than a change in par value
or a subdivision or combination as provided for in Section 3(c) above), or any
consolidation or merger of the Company with or into another corporation, or a
transfer of all or substantially all of the assets of the Company, then, as part
of any such reorganization, reclassification, consolidation, merger or sale, as
the case may be, lawful provision shall be made so that the Registered Holder of
this Warrant shall have the right thereafter to receive upon the exercise hereof
the kind and amount of shares of stock or other securities or property which
such Registered Holder would have been entitled to receive if, immediately prior
to any such reorganization, reclassification, consolidation, merger or sale, as
the case may be, such Registered Holder had held the number of shares of Common
Stock which were then purchasable upon the exercise of this Warrant. In any such
case, appropriate adjustment (as reasonably determined in good faith by the
Board of Directors of the Company) shall be made in the application of the
provisions set forth herein with respect to the rights and interests thereafter
of the Registered Holder of this Warrant, such that the provisions set forth in
this Section 3 (including provisions with respect to adjustment of the Purchase
Price) shall thereafter be applicable, as nearly as is reasonably practicable,
in relation to any shares of stock or other securities or property thereafter
deliverable upon the exercise of this Warrant.

          (e)  Adjustment in Number of Warrant Shares.  When any adjustment is
               --------------------------------------                         
required to be made in the Purchase Price, the number of Warrant Shares
purchasable upon the exercise of this Warrant shall be changed to the number
determined by dividing (i) an amount equal to the number of shares issuable upon
the exercise of this Warrant immediately prior to such adjustment, multiplied by

                                      -5-
<PAGE>
 
the Purchase Price in effect immediately prior to such adjustment, by (ii) the
Purchase Price in effect immediately after such adjustment.

          (f)  Certificate of Adjustment.  When any adjustment is required to be
               -------------------------                                        
made pursuant to this Section 3, the Company shall promptly mail to the
Registered Holder a certificate setting forth the Purchase Price after such
adjustment and setting forth a brief statement of the facts requiring such
adjustment. Such certificate shall also set forth the kind and amount of stock
or other securities or property into which this Warrant shall be exercisable
following such adjustment.

          (g)  Adustments for Non-Stock Dividends and Distributions.  In the
               ----------------------------------------------------         
event that the Company shall issue or pay to holders of Common Stock a dividend
or other distribution payable other than in securities of the Company, then and
in each such event provision shall he made so that Holder shall receive upon
exercise of this Warrant, in addition to the Warrant Shares issued upon
exercise, the dividend or other distribution which Holder would have received if
it had been the holder of such Warrant Shares at the time of such dividend or
other distribution.

     4.   Acquisition Transaction.  If the Company undertakes an Acquisition
          -----------------------                                           
Transaction then, simultaneously with and as a condition to the Acquisition
Transaction, the Company shall, at its election, either (i) cause the Company
Acquiror (as defined below) to assume this Warrant and cause provision to be
made so that the Holder shall thereafter be entitled to receive, upon exercise
of this Warrant, the Warrant Shares, whereupon the Company shall be released
from this Warrant, or (ii) cause the Company Acquiror to pay the Warrant Value
(as defined below) to the Holder upon consummation of the Acquisition
Transaction. If this Warrant becomes exercisable by reason of an Acquisition
Transaction and the Company does not cause the Company Acquiror to pay the
Warrant Value to the Holder, this Warrant shall remain outstanding in accordance
with its terms and all references herein to the "Company" shall thereafter be
deemed to apply to the Company Acquiror and all references herein to the
"Warrant Shares" shall thereafter be deemed to apply to the common stock of the
Company Acquiror. "Company Acquiror" shall mean the Company or other entity, as
applicable, surviving the Acquisition Transaction. "Warrant Value" shall mean
the lesser of (i) the Maximum Security Return and (ii) the fair market value of
this Warrant immediately prior to the closing of the Acquisition Transaction
("Fair Market Value"), as determined by an investment banking firm of
established national reputation selected by the Holder and stated in a written
opinion delivered to the Company and the Holder. The fees and expenses of such
investment banking firm shall be shared equally by the Company and the Holder
and its determination of the Fair Market Value shall be conclusive and binding
on all parties in the absence of fraud or manifest error.

     5.   Acquisition or IPO by Subsidiary.
          -------------------------------- 

          (a)  IPO by Subsidiary.  If, prior to an IPO, the Company transfers 
               -----------------                                               
all or substantially all of its assets to any direct or indirect wholly owned
subsidiary (a "Subsidiary") and the Subsidiary subsequently undertakes a
transaction which would constitute an IPO (a "Subsidiary IPO") if undertaken by
the Company, then, simultaneously with and as a condition to the Subsidiary IPO,
the Subsidiary shall assume this Warrant, provision shall be made so that the
Holder shall be entitled to receive, upon exercise of this Warrant, shares of
stock or other securities or property of the Subsidiary to which it is entitled
under this Warrant, and the Company shall be released from this Warrant.

          (b)  Acquisition of Subsidiary.  If, prior to an Acquisition
               -------------------------                              
Transaction, the Company transfers all or substantially all of its assets to a
Subsidiary and the Subsidiary subsequently undertakes a transaction which would
constitute an Acquisition Transaction (a "Subsidiary Acquisition") if undertaken
by the Company, then, simultaneously with and as a condition to the Subsidiary
Acquisition, the Company shall, at its election, either (i) cause the Subsidiary
Acquiror (as

                                      -6-
<PAGE>
 
defined below) to assume this Warrant and cause provision to be made so that the
Holder shall thereafter be entitled to receive, upon exercise of this Warrant,
the Warrant Shares, whereupon the Company shall be released from this Warrant,
or (ii) cause the Subsidiary Acquiror to pay the Warrant Value (as defined
above, except that references to Acquisition Transaction shall mean Subsidiary
Acquisition) to the Holder upon consummation of the Subsidiary Acquisition. If
this Warrant becomes exercisable by reason of a Subsidiary Acquisition and the
Subsidiary does not cause the Subsidiary Acquiror to pay the Warrant Value to
the Holder, this Warrant shall remain outstanding in accordance with its terms
and all references herein to the "Company" shall thereafter be deemed to apply
to the Subsidiary Acquiror and all references herein to the "Warrant Shares"
shall thereafter be deemed to apply to the common stock of the Subsidiary
Acquiror. "Subsidiary Acquiror" shall mean the Subsidiary or other entity, as
applicable, surviving the Subsidiary Acquisition.

     6.   Fractional Shares.  The Company shall not be required upon the
          -----------------                                             
exercise of this Warrant to issue any fractional shares, but shall make an
adjustment therefor in cash on the basis of the fair market value per share of
Common Stock, as determined in good faith by the Company's Board of Directors.

     7.   Registration Rights.  The Warrant Shares shall be considered
          -------------------                                         
Restricted Stock for all purposes of the Note, including without limitation the
registration rights set forth in the Note.

          (i)   Any shares purchased upon exercise of this Warrant shall be
     acquired for the Holder's account for investment only and not with a view
     to, or for sale in connection with, any distribution of the shares in
     violation of the Securities Act of 1933, as amended (the "Securities Act"),
     or any rule or regulation under the Securities Act.

          (ii)  The Holder has had such opportunity as it has deemed adequate to
     obtain from representatives of the Company such information as is necessary
     to permit the Holder to evaluate the merits and risks of its investment in
     the Company.

          (iii) The Holder is able to bear the economic risk of holding shares
     acquired pursuant to the exercise of this Warrant for an indefinite period.

          (iv)  The Holder understands that (A) the shares acquired pursuant to
     the exercise of this Warrant will not be registered under the Securities
     Act and are "restricted securities" within the meaning of Rule 144 under
     the Securities Act, (B) such shares cannot be sold, transferred or
     otherwise disposed of unless they are subsequently registered under the
     Securities Act or an exemption from registration is then available and (C)
     there is now no registration statement on file with the Securities and
     Exchange Commission with respect to any stock of the Company and (except as
     contemplated by Section 7 above) the Company has no obligation or current
     intention to register any shares acquired pursuant to the exercise of this

By making payment upon exercise of this Warrant, the Holder shall be deemed to
have reaffirmed, as of the date of such payment, the representations made in
this Section 8.

     registered under the Securities Act of 1933 and may not be transferred,
     sold or otherwise disposed of in the absence of an effective registration
     statement with respect to the shares evidenced by this certificate, filed
     and made effective under the Securities Act of 1933, or an opinion of
     counsel satisfactory to the Company to the effect that registration under
     such Act is not required."

     9.   Reservation of Stock.  The Company will at all times reserve and keep

11 April, 1996

Mr. Greg Carr
Co-Chairman of the Board
International Wireless, Inc.

Dear Greg,

Please consider the following as the agreed upon structure reached between Grupo
Carso, S.A. de C.V. (GC), or any of its subsidiaries, and International
Wireless, Inc. (IW) for the purchase of IW stock by GC.

     Phase 1:  (February 20, 1996)
               One million shares purchased directly from IW at $3.00 per share.

     Phase 2:  (March 11, 1996)
               Two million shares purchased directly from IW at $3.00 per share.

     Phase 3:  (May 1, 1996)
               One million shares purchased directly from IW at $3.00 per share.

     Phase 4:  (September 3, 1996)
               Three million shares purchased directly from IW at $3.00 per
               share.

In addition, GC and IW agree that GC shall be allowed to purchase an additional
three million shares from existing shareholders. In conjunction with this, GC
agrees, for a period beginning on the date hereof and ending on February 28,
2004, that it shall not, directly or indirectly, without the prior written
consent of the company, purchase, acquire or own, any securities of the Company
other than (i) any securities which may be issued with respect to the Purchaser
Shares as a result of any stock dividend, stock split, combination or other
similar recapitalization.

It is understood that at the completion of the aforementioned, GC will own ten
million IW shares representing approximately 21%-23% of the company to date, and
that these shares are full voting common shares equal in all respect to all
other common shares of the Company, and the Company has issued no other class of
stock. (I reference your letter dated 7 March, 1996.)

It is also understood that it is the intention of IW to issue an additional 3-4
million new shares of IW in the form of a "private placement" in the next six
months, and that IW will do so only after consulting with GC.

As agreed this 11th day of April, 1996.

purchase fully-paid and nonassessable shares of Common Stock from International

Carso and Carr.  Each exercise of the Stock Put must be authorized by a majority

(as so amended, the "Funding Agreement"); and

     WHEREAS, Prodigy, Carso Global and Mr. Carr wish to make certain
modifications to the Funding Agreement, as set forth herein;

     NOW, THEREFORE, for good and valuable consideration, Prodigy, Carso Global
and Mr. Carr hereby agree as follows:

     1.   Stock Put.

allocated $65 million to Carso Global and $15 million to Mr. Carr.  Within two
business days after the date hereof, Mr. Carr and Carso Global shall provide
such respective amounts to Prodigy in immediately available funds or, in the
case of Mr. Carr, through the cancellation of indebtedness owed by Prodigy to
Mr. Carr.  Of the $65 million to be provided by Carso Global, $40 million shall
be paid directly by Carso Global to Banco Inbursa, S.A. on Prodigy's behalf in
repayment of $40 million of the indebtedness owed by Prodigy to Banco Inbursa,
S.A., and the remaining $25 million shall be paid to Prodigy.

          1.2  HSR Act.
               ------- 

               (a)  Prodigy, Mr. Carr and Carso Global, as promptly as
practicable after the date hereof, shall prepare and file all Notification and
Report Forms and related material that they are required to file with the U.S.

Justice under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended (the "HSR Act"), with respect to the exercise of the stock put described
in Section 1.1 above, and shall use their respective best efforts to obtain an
early termination of the applicable waiting period and shall make any further
filings or information submissions pursuant thereto that may be necessary,
proper or advisable. Prodigy shall pay all applicable filing fees under the HSR
Act.

               (b)  The proceeds of the stock put specified in Section 1.1 above

               (c)  If the waiting period pursuant to the HSR Act has not
terminated or expired on or before the 60th day after Prodigy, Mr. Carr and
Carso Global have each filed all Notification and Report Forms and related
material required to be filed under the HSR Act, the proceeds of the stock put
specified in Section 1.1 above shall automatically convert into the following:

Prodigy on terms that are identical to the terms of the existing loan of $50
million from Banco Inbursa, S.A. to Prodigy

(originally made to International Wireless Incorporated), including without
limitation the stock pledges from Mr. Carr and Carso Global (originally from
Orient Star Holdings) to secure such loan, except that the amount of the loan
shall be $65 million and not $50 million and the lender shall be Carso Global
and not Banco Inbursa, S.A., and (ii) with respect to Mr. Carr, a loan of $15
million from Mr. Carr to Prodigy on terms that are identical to the terms of the

          1.3  Remaining Put.  The parties agree that after the exercise of the
               -------------

million, allocated $39 million to Carso Global and $6 million to Mr. Carr.  The
remaining stock put shall not be reduced by the proceeds of any exercise of the
Warrants described in Section 2.2 below but shall be subject to reduction as
provided in Section 5.1 of the Funding Agreement. All exercises and reductions
of the remaining put shall be allocated in the ratio of 13/15 to Carso Global

                           STOCK PURCHASE AGREEMENT


     AGREEMENT effective as of the 24th day of July, 1998 among Greg C. Carr, an
individual residing in Cambridge, Massachusetts ("Carr"), Prodigy, Inc., a
Delaware corporation ("Prodigy"), Telefonos de Mexico, S.A. de C.V., a Mexican
corporation ("Telmex"), and Carso Global Telecom, S.A. de C.V., a Mexican
corporation ("Carso Global").

     WHEREAS, concurrently with the execution of this Agreement, Telmex and
Prodigy are entering into a Stock Purchase Agreement (the "Prodigy/Telmex
Agreement") pursuant to which, among other things, Telmex has agreed to make an
equity investment in Prodigy; and

     WHEREAS, it is a condition to the execution of the Prodigy/Telmex Agreement
that this Agreement be entered into and it is a condition to the execution of
this Agreement that the Prodigy/Telmex Agreement be entered into;

     NOW, THEREFORE, in consideration of the mutual promises hereinafter set
forth and other good and valuable consideration, the receipt of which is hereby
acknowledged, the parties hereby agree as follows:

     1.   Purchase and Sale of the Shares.
          ------------------------------- 

          (a) Carr agrees to sell to Telmex, and Telmex agrees to purchase from
Carr, 13,000,000 shares (the "Shares") of Prodigy's Common Stock, $.01 par value
per share ("Common Stock"), owned by Carr.  Telmex acknowledges that Carr
intends to acquire up to 3,000,000 shares of Common Stock from members of his
family and/or other persons at U.S. $2.00 per share in order to permit Carr to
sell 13,000,000 shares to Telmex.  The purchase price for the Shares shall be
U.S. $2.00 per Share, the same price to be paid by Telmex for its equity
investment in Prodigy pursuant to the Prodigy/Telmex Agreement.

          (b) If, at any time prior to the Initial Closing (as defined in
Section 2 below) or within 180 days after the Initial Closing, Telmex, Carso
Global, Prodigy or any of their respective affiliates shall purchase or sell, or
agree to purchase or sell, any shares of Common Stock to or with third parties
in a Qualifying Transaction (as defined below) at a price in excess of U.S.
$2.00 per Share (as proportionately adjusted for any stock splits, stock
dividends or similar events affecting the Common Stock, the "Base Price"),
Telmex shall (i) promptly give written notice thereof to Carr and (ii) within
three business days following the closing of the Qualifying Transaction, pay to
Carr the amount per Share by which the price in the Qualifying Transaction
exceeds the Base Price (the "Differential") multiplied by the number of Shares;
provided, however, that in no event shall the Differential required to be paid
- --------  -------                                                             
to Carr exceed U.S. $.40 per Share (as proportionately adjusted for any stock
splits, stock dividends or similar events affecting the Common Stock) regardless
of the price at which shares are sold in a Qualifying Transaction.  For this
purpose, a "Qualifying Transaction" shall mean a sale or purchase, or a series
of related sales or purchases, of Common Stock involving an aggregate of at
least U.S. $500,000, but in no event shall include (i) transactions under
employee stock or option plans or (ii) transfers without consideration among or
between Telmex, Carso Global or Prodigy and any of their respective affiliates.
Any amounts due to Carr under this Section 1(b) which remain unpaid after three
business days following the closing of the Qualifying Transaction shall bear
interest at an annual rate of 9% until paid, and Telmex agrees to indemnify Carr
for any damages and expenses, including fees and disbursements of counsel,
suffered or incurred by Carr in enforcing Telmex's obligations under this
Section 1(b).

hereby terminated.

          (b) Effective as of the Initial Closing, Carr hereby resigns as
Chairman of the Board of Prodigy and as a member of the Compensation Committee
of Prodigy's Board of Directors.  As of the Initial Closing, Carr's annual
director fee of U.S. $135,000 shall terminate.  From and after the Initial
Closing, Carr shall not be entitled to any further compensation for service as a
director (other than on the same basis, if any, as other non-employee directors
of Prodigy from time to time), and Prodigy shall not be required to provide Carr
with any health insurance or other employee benefits of any kind.

          (c) Until the first anniversary of the Initial Closing or such earlier
date as Carr shall cease to own any Common Stock or resign (the "Board
Termination Date"), Carr shall be entitled to continue to serve as a member of
the Board of Directors of Prodigy and its subsidiaries.  Each of Carso Global
and Telmex agrees to vote all shares over which they (or their respective
affiliates) exercise voting control, and otherwise to use their respective best
efforts, so as to effectuate the preceding sentence.  Upon the Board Termination
Date, Carr shall resign as a member of the Board of Directors of Prodigy and its
subsidiaries.

          (d) For a period of six years after the Initial Closing, Prodigy shall
not amend the indemnification provisions of its Certificate of Incorporation or
By-Laws as now existing in any manner which limits, restricts or otherwise
adversely affects the rights afforded to Carr under such provisions.

          (e) Prodigy agrees, at Prodigy's expense, to continue to defend and
indemnify Carr in any threatened, pending or completed lawsuits filed by or on
behalf of any of Malcome Haynes, Lightwave, Ltd., Comstar Cellular Network, Inc.
(Nevada) or Comstar Cellular Network, Inc. (Texas) or their respective
affiliates, subsidiaries, successors, heirs or assigns, now or hereafter
existing (collectively, "Haynes Claimants"), and any appeals therefrom, with
counsel selected by Prodigy (currently Hale and Dorr LLP) and reasonably
acceptable to Carr.

          (f) Prodigy shall not settle or compromise any claim, or default or
otherwise fail to oppose entry of judgment against it on any claim, asserted or
which may be asserted against it by or on behalf of any of the Haynes Claimants,
without the consent of Carr, which shall not be unreasonably withheld or
delayed.  Carr shall not settle or compromise any claim, or default or otherwise
fail to oppose entry of judgment against him on any claim, asserted or which may
be asserted against him by or on behalf of any of the Haynes Claimants, without
the consent of Prodigy, which shall not be unreasonably withheld or delayed.

     4.   Termination of Prior Stock Pledge.
          --------------------------------- 

          (a) As of the Initial Closing (as defined in Section 2 above), Carso
Global shall cause to be terminated Carr's pledge of 10,000,000 shares of Common
Stock (the "Pledged Shares") to secure Prodigy's obligations to Banco Inbursa,
S.A. ("Banco Inbursa") pursuant to that certain Pledge and Escrow Agreement
dated as of June 14, 1996 among Carr, Orient Star Holdings, Banco Inbursa and
State Street Bank and Trust Company ("State Street").  On or before the Initial
Closing or as soon as practicable

<PAGE>
 
thereafter, Carso Global shall cause the original stock power relating to the
Pledged Shares previously executed by Carr and delivered to State Street to be
returned to Carr.

          (b) On or before the Initial Closing or as soon as practicable
thereafter, Carso Global shall cause the original stock certificate representing
the Pledged Shares to be delivered to Telmex to be held pursuant to the Pledge
Agreement (as defined in Section 6(b)(iii) below).

          (c) From and after the Initial Closing, Carr shall have no obligation
to guaranty, or to pledge any shares or provide any other collateral to secure,
Prodigy's obligations to Banco Inbursa or any other entity.

     5.   Funding Obligations.

          (a) Prodigy and Carso Global acknowledge and agree that Carr has fully
performed his funding obligations to Prodigy pursuant to (i) that certain
Funding Agreement dated as of May 12, 1996 among Prodigy (as successor to

Commission and the Antitrust Division of the U.S. Department of Justice under
the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act"), with respect to the transactions contemplated hereby, and shall use their
respective best efforts to obtain an early termination of the applicable waiting

<PAGE>
 
          (c) Subject to Section 6(d), the final closing shall occur upon the
termination or expiration of the applicable waiting period pursuant to the HSR
Act (the "Final Closing").  At the Final Closing, the following events shall
occur:

              (i)  The Pledge Agreement shall terminate and the Shares shall be
transferred to Telmex in full satisfaction of Carr's obligations under the Note
(it being agreed that Carr shall have the right to deliver and transfer to
Telmex at the Final Closing any 13,000,000 shares of Common Stock then held by
him, and not necessarily the 13,000,000 shares of Common Stock held under the
Pledge Agreement, and the 13,000,000 shares of Common Stock so delivered by Carr
shall constitute the "Shares" for all purposes of this Agreement); and

              (ii) Telmex shall return to Carr the original Note marked
"cancelled" in return for the transfer of the Shares to Telmex.

          (d) Notwithstanding the foregoing, in the event that the Note is not
repaid in full on or before the 60th day after Telmex has filed its Notification
and Report Form and any related material required to be filed by it under the
HSR Act in accordance with Section 6(a), the Pledge Agreement shall continue in
effect and the Note shall bear interest at an annual rate of nine percent (9%),
accruing from the Initial Closing.  The Note may be prepaid in whole or in part,
at any time and from time to time at the election of Carr, but in any event the
principal amount of the Note, together with accrued interest, shall be due in
full on December 31, 1999.

     7.   Co-Sale Right.
          ------------- 

          (a) If, at any time after the Initial Closing and on or before the
earlier of (i) the first anniversary of the Initial Closing or (ii) the
completion of Prodigy's initial public offering of Common Stock (the "IPO"),
Telmex or Carso Global (a "Seller") propose to sell (other than in connection
with the IPO) to third parties any Common Stock held by them, the Seller shall
notify Carr of the number of shares to be sold and the price and other terms of
such sale (the "Seller Notice").  By giving notice to the Seller within 20 days
after the Seller Notice, Carr shall have the right, but not the obligation, to
sell, at the price and on the other terms set forth in the Seller Notice, a
portion of the shares to be sold in such sale in the same proportion as the
number of shares of Common Stock then owned by Carr bears to the number of
shares of Common Stock then owned by the Seller.  Carr covenants and agrees not
to exercise his co-sale right with respect to any shares of Common Stock which
are subject to warrants granted by Carr.

          (b) Any sale of Common Stock by a Seller without compliance with this
Section 7 shall be void and shall transfer no right, title or interest in or to
any such shares to the purported transferee.  The proceeds of any sale made by a
Seller without compliance with this Section 7 shall be deemed to be held in
constructive trust in such amount as would have been paid to Carr if the Seller
had complied with this Section 7.  The contents of such constructive trust shall
be delivered to Carr upon surrender of the appropriate number of shares of
Common Stock.

     8.   Representations and Warranties of Carr.  Carr represents and warrants

              ------ 

              (a) At the date hereof, Carr owns 20,413,766 shares of Common
Stock, of which 187,500 shares are subject to outstanding warrants granted by
Carr. All such shares are owned by Carr beneficially and of record, except for
the pledge of the Pledged Shares to be released at the Final Closing. At the

Shares shall cease to be Registrable Shares upon any sale pursuant to a
Registration Statement, Section 4(1) or Section 4(2) of the Securities Act or
Rule 144 under the Securities Act (or any combination thereof), or any sale in
any manner to a person or entity which, by virtue of Section 14 hereof, is not
entitled to the rights provided hereby.

          "Securities Act" means the Securities Act of 1933, as amended, or any

     2.   [This Section intentionally left blank]
 
     3.   Incidental Registration.
          ----------------------- 

          (a) Whenever the Company proposes to file a Registration Statement at
any time and from time to time in which Telmex or Carso Global or any of their
affiliates propose to sell any shares of Common Stock of the Company, it will,
prior to such filing, give written notice to the Shareholders of its intention
to do so and, upon the written request of a Shareholder or Shareholders given
within 10 days after the Company provides such notice (which request shall state
the intended method of disposition of such Registrable Shares), the Company
shall use its best efforts to cause all Registrable Shares which the Company has
been requested by such Shareholders to register to be registered under the
Securities Act to the extent necessary to permit their sale or other disposition
in accordance with the intended methods of distribution specified in the request
of such Shareholders; provided that the Company shall have the right to postpone
or withdraw any registration effected pursuant to this Section 3 without
obligation to any Shareholder.

          (b) In connection with any offering under this Section 3 involving an
underwriting, the Company shall not be required to include any Registrable
Shares in such offering unless the holders thereof accept the terms of the
underwriting as agreed upon between the Company and the underwriters selected by
it (provided that such terms must be consistent with this Agreement).  If in the
opinion of the managing underwriter it is appropriate because of marketing
factors to limit the number of Registrable Shares to be included in the
offering, then the Company shall be required to include in the offering only
that number of Registrable Shares, if any, which the managing underwriter
believes should be included therein; provided that (i) no persons or entities
other than the Company, the 

                                      -2-
<PAGE>
 
Shareholders, Telmex or Carso Global or any of their affiliates, and persons or
entities holding registration rights granted in accordance with Section 10
hereof, shall be permitted to include securities in the offering without the
consent of the holder of a majority of the Registrable Shares then outstanding
and (ii) the holders of Registrable Shares who have requested registration and
other holders of securities entitled to include them in such registration shall
participate in the underwriting pro rata based upon their total ownership of
                                --- ----           
shares of Common Stock of the Company (giving effect to the conversion into
Common Stock of all securities convertible thereinto). If any holder would thus
be entitled to include more securities than such holder requested to be
registered, the excess shall be allocated among other requesting holders pro
                                                                         ---  
rata in the manner described in the preceding sentence.

     4.   Registration Procedures.  If and whenever the Company is required by
          -----------------------                                             
the provisions hereof to effect the registration of any of the Registrable
Shares under the Securities Act, the Company shall:

          (a) file with the Commission a Registration Statement with respect to
such Registrable Shares and use its best efforts to cause that Registration
Statement to become and remain effective for 45 days from the effective date or
such lesser period until all such Registrable Shares are sold;

          (b) as expeditiously as possible prepare and file with the Commission
any amendments and supplements to the Registration Statement and the prospectus
included in the Registration Statement as may be necessary to keep the
Registration Statement effective, (i) in the case of a firm commitment
underwritten public offering, until each underwriter has completed the
distribution of all securities purchased by it, and (ii), in the case of any
other offering, until the earlier of the sale of all Registrable Shares covered
thereby or 45 days after the effective date thereof;

          (c) as expeditiously as possible furnish to the selling Shareholders
such reasonable numbers of copies of the prospectus, including a preliminary
prospectus, in conformity with the requirements of the Securities Act, and such
other documents as the selling Shareholders may reasonable request in order to
facilitate the public sale or other disposition of the Registrable Shares owned
by the selling Shareholders; and

          (d) as expeditiously as possible use its best efforts to register or
qualify the Registrable Shares covered by the Registration Statement under the
securities or Blue Sky laws of such states as the selling Shareholders shall
reasonably request, and do any and all other acts and things that may be
necessary or desirable to enable the selling Shareholders to consummate the
public sale or other disposition in such states of the Registrable Shares owned
by the selling Shareholders; provided, however, that the Company shall not be
                             --------  -------                               
required in connection with this paragraph (d) to qualify as a foreign
corporation or execute a general consent to service of process in any
jurisdiction.

                                      -3-
<PAGE>
 
     If the Company has delivered preliminary or final prospectuses to the
selling Shareholders and after having done so the prospectus is amended to
comply with the requirements of the Securities Act, the Company shall promptly
notify the selling Shareholders and, if requested, the selling Shareholders
shall immediately cease making offers of Registrable Shares and return all
prospectuses to the Company.  The Company shall promptly provide the selling
Shareholders with revised prospectuses and, following receipt of the revised
prospectuses, the selling Shareholders shall be free to resume making offers of
the Registrable Shares.

     In the event that, in the judgment of the Company, it is advisable to
suspend use of a prospectus included in a Registration Statement due to pending
material developments or other events that have not yet been publicly disclosed
and as to which the Company believes public disclosure would be detrimental to
the Company, the Company shall notify all selling Shareholders to such effect,
and, upon receipt of such notice, each such Shareholder shall immediately
discontinue any sales of Registrable Shares pursuant to such Registration
Statement until such Shareholder has received copies of a supplemented or
amended prospectus or until such Shareholder is advised in writing by the
Company that the then current prospectus may be used and has received copies of
any additional or supplemental filings that are incorporated or deemed
incorporated by reference in such prospectus. Notwithstanding anything to the
contrary herein, the Company shall not exercise its rights under this paragraph
to suspend sales of Registrable Shares for a period in excess of 90 days in any
365-day period.

     5.   Allocation of Expenses.  The Company will pay all Registration
          ----------------------                                        
Expenses of all registrations hereunder.  For purposes of this Section, the term
"Registration Expenses" shall mean all expenses incurred by the Company in
complying with this Agreement, including, without limitation, all registration
and filing fees, exchange listing fees, printing expenses, fees and
disbursements of counsel for the Company, state Blue Sky fees and expenses, and
the expense of any special audits incident to or required by any such
registration, but excluding underwriting discounts and selling commissions and
the fees and expenses of counsel for the selling Shareholders.

     6.   Indemnification and Contribution.
          -------------------------------- 

          (a) In the event of any registration of any of the Registrable Shares
under the Securities Act pursuant to this Agreement, the Company will indemnify
and hold harmless the seller of such Registrable Shares, each underwriter of
such Registrable Shares, and each other person, if any, who controls such
sellers or underwriter within the meaning of the Securities Act or the Exchange
Act, against any losses, claims, damages or liabilities, joint or several, to
which such seller, underwriter or controlling person may become subject under
the Securities Act, the Exchange Act, state securities or Blue Sky laws or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in any Registration Statement
under which such Registrable Shares were registered under the 

                                      -4-
<PAGE>
 
Securities Act, any preliminary prospectus or final prospectus contained in the
Registration Statement, or any amendment or supplement to such Registration
Statement, or arise out of or are based upon the omission or alleged omission to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading; and the Company will reimburse such seller,
underwriter and each such controlling person for any legal or any other expenses
reasonably incurred by such seller, underwriter or controlling person in
connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the Company will not be liable in
                     --------  ------- 
any such case to the extent that any such loss, claim, damage or liability
arises out of or is based upon any untrue statement or omission made in such
Registration Statement, preliminary prospectus or final prospectus, or any such
amendment or supplement, in reliance upon and in conformity with information
furnished to the Company, in writing, by or on behalf of any seller, underwriter
or controlling person specifically for use in the preparation thereof.

          (b) In the event of any registration of any of the Registrable Shares
under the Securities Act pursuant to this Agreement, each seller of Registrable
Shares, severally and not jointly, will indemnify and hold harmless the Company,
each of its directors and officers and each underwriter (if any) and each
person, if any, who controls the Company or any such underwriter within the
meaning of the Securities Act or the Exchange Act, against any losses, claims,
damages or liabilities, joint or several, to which the Company such directors
and officers, underwriter or controlling person may become subject under the
Securities Act, Exchange Act, state securities or Blue Sky laws or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in any Registration Statement under which
such Registrable Shares were registered under the Securities Act, any
preliminary prospectus or final prospectus contained in the Registration
Statement, or any amendment or supplement to the Registration Statement, or
arise out of or are based upon any omission or alleged omission to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading, if the statement or omission was made in reliance upon
and in conformity with information furnished in writing to the Company by or on
behalf of such seller, specifically for use in connection with the preparation
of such Registration Statement, prospectus, amendment or supplement; provided,
                                                                     -------- 
however, that the obligations of such Shareholders hereunder shall be limited to
- -------                                                                         
an amount equal to the proceeds to each Shareholder of Registrable Shares sold
in connection with such registration.

          (c) Each party entitled to indemnification under this Section 6 (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom; provided, that counsel for the Indemnifying
                                --------                                   
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not be unreasonably
withheld); and, provided, further, that the failure of any Indemnified Party to
                --------  -------                                              
give notice as provided herein shall not relieve the Indemnifying Party of its
obligations under this Section 

                                      -5-
<PAGE>
 
6. The Indemnified Party may participate in such defense at such party's
expense; provided, however, that the Indemnifying Party shall pay such expense
         --------  -------                             
if representation of such Indemnified Party by the counsel retained by the
Indemnifying Party would be inappropriate due to actual or potential differing
interests between the Indemnified Party and any other party represented by such
counsel in such proceeding; provided further that in no event shall the
                            -------- -------        
Indemnifying Party be required to pay the expenses of more than one law firm per
jurisdiction as counsel for the Indemnified Party. The Indemnifying Party also
shall be responsible for the expenses of such defense if the Indemnifying Party
does not elect to assume such defense. No Indemnifying Party, in the defense of
any such claim or litigation shall, except with the consent of each Indemnified
Party, consent to entry of any judgment or enter into any settlement which does
not include as an unconditional term thereof the giving by the claimant or
plaintiff to such Indemnified Party of a release from all liability in respect
of such claim or litigation, and no Indemnified Party shall consent to entry of
any judgment or settle such claim or litigation without the prior written
consent of the Indemnifying Party.

          (d) In order to provide for just and equitable contribution to joint
liability under the Securities Act in any case in which either (i) any holder of
Registrable Shares exercising rights hereunder, or any controlling person of any
such holder, makes a claim for indemnification pursuant to this Section 6 but it
is judicially determined (by the entry of a final judgment or decree by a court
of competent jurisdiction and the expiration of time to appeal or the denial of
the last right of appeal) that such indemnification may not be enforced in such
case notwithstanding the fact that this Section 6 provides for indemnification
in such case, or (ii) contribution under the Securities Act may be required on
the part of any selling Shareholder or any such controlling person in
circumstances for which indemnification is provided under this Section 6; then,
in each such case, the Company and such Shareholder will contribute to the
aggregate losses, claims, damages or liabilities to which they may be subject
(after contribution from others) in such proportions so that such holder is
responsible for the portion represented by the percentage that the public
offering price of its Registrable Shares offered by the Registration Statement
bears to the public offering price of all securities offered by such
Registration Statement, and the Company is responsible for the remaining
portion; provided, however, that, in any such case, (A) no such holder will be
         --------  -------                                                    
required to contribute any amount in excess of the proceeds to it of all
Registrable Shares sold by it pursuant to such Registration Statement, and (B)
no person or entity guilty of fraudulent misrepresentation, within the meaning
of Section 11(f) of the Securities Act, shall be entitled to contribution from
any person or entity who is not guilty of such fraudulent misrepresentation.
Any party entitled to contribution will, promptly after receipt of notice of
commencement of any action, suit or proceeding against such party in respect of
which a claim for contribution may be made against another party or parties
under this Section 6, notify such party or parties from whom contribution may be
sought, but the omission so to notify such party or parties from whom
contribution may be sought shall not relieve such party from any other
obligation it or they may have thereunder or otherwise under this Section.  No
party shall be liable for contribution with respect to any action, suit,
proceeding or claim settled without its prior written consent.

     7.   Indemnification with Respect to Underwritten Offering.  In the event
          -----------------------------------------------------               
that Registrable Shares are sold pursuant to a Registration Statement in an
underwritten offering pursuant to Section 3, the Company agrees to enter into an
underwriting agreement containing customary representations and warranties with
respect to the business and operations of an issuer of the securities being
registered and customary covenants and agreements to be performed by such
issuer, including without limitation customary provisions with respect to
indemnification by the Company of the underwriters of such offering.

     8.   Information by Holder.  Each Shareholder including Registrable Shares
          ---------------------                                                
in any registration shall furnish to the Company such information regarding such
Shareholder and the distribution proposed by such Shareholder as the Company may
reasonably request in writing and as shall be required in connection with any
registration, qualification or compliance referred to herein.

     9.   "Stand-Off" Agreement.  The Shareholders, if requested by the Company
          ---------------------                                                
and the managing underwriter of an offering by the Company of Common Stock or
other securities of the Company pursuant to a Registration Statement, shall
agree not to sell or otherwise transfer or dispose of any Registrable Shares or
other securities of the Company held by such Shareholders (except pursuant to
the Purchase Agreement) for a specified period of time (not to exceed one
hundred eighty (180) days) following the effective date of such Registration
Statement; provided, that all shareholders of the Company holding not less than
           --------                                                            
the number of shares of Common Stock held by such Shareholder (including
convertible securities, or upon the exercise of options, warrants or rights) and
all executive officers and directors of the Company enter into similar
agreements.

     l0.  Limitations on Subsequent Registration Rights.  The Company shall not,
          ---------------------------------------------                         
without the prior written consent of the Shareholders holding at least a
majority of the Registrable Shares, enter into any agreement with any holder or
prospective holder of any securities of the Company which would allow such
holder or prospective holder the right to register or cause the registration of,
any securities of the Company, except for registration rights which are pari
passu with those provided to the Shareholders under Section 3 hereof.

     ll.  Rule l44 Requirements.  After the earliest of (i) the closing of the

said Rule l44(c), and the reporting requirements of the Securities Act and the

requirements), (ii) a copy of the most recent annual or quarterly report of the
Company, and (iii) such other reports and documents of the Company as such
holder may reasonably request to avail itself of any similar rule or regulation
of the Commission allowing it to sell any such securities without registration.

     12.  Termination.  All of the Company's obligations to register Registrable
          -----------

into any merger, consolidation or reorganization in which the Company shall not
be the surviving corporation unless the proposed surviving corporation shall,
prior to such merger, consolidation or reorganization, agree in writing to
assume the obligations of the Company hereunder, and for that purpose references
hereunder to "Registrable Shares" shall be deemed to be references to the
securities which the Shareholders would be entitled to receive in exchange for
Registrable Shares under any such merger, consolidation or reorganization;
provided, however, that the provisions of this Section 13 shall not apply in the
- --------  -------                                                               
event of any merger, consolidation or reorganization in which the Company is not

hereof.

          (b) Any transferee to whom rights hereunder are transferred shall, as
a condition to such transfer, deliver to the Company a written instrument by

transfer of such rights, indicates the Registrable Shares owned by it and agrees
to be bound by the obligations imposed upon Shareholder hereunder.

B.   GENERAL TERMS

1.   The "Territory" shall be defined as Customer facilities worldwide, subject
     to U.S. export laws.

2.   Customer. For purposes of this Order Form, Customer shall be defined as
     --------
     Prodigy Services Corporation ("PSC"), PSC's majority owned subsidiaries
     ("Subsidiaries"), and majority owned subsidiaries of PSC's parent
     corporation Prodigy, Inc. ("Parent Subsidiaries") located in the Territory
     as of the Effective Date. Subsidiaries and Parent Subsidiaries formed after
     the Effective Date may be included as a Customer with Oracle's prior
     written consent. For purposes of this Order Form only, the entity or
     entities that provide the internet service(s) known as "ProdigyChina",
     "SinoTelecom" and/or "ProdigyAsia", or its a successor entity, shall be
     deemed to be a Parent Subsidiary regardless of whether such entities are
     majority owned subsidiaries of Prodigy, Inc. Before accessing the Programs,
     each Subsidiary, Parent Subsidiary and Future Subsidiaries must agree in
     writing to be bound by the terms of the Agreement and this Order Form.
     Whether each Subsidiary and Parent Subsidiary elects to use and access the
     Programs shall be at the sole discretion of each Subsidiary and Parent
     Subsidiary.

3.   Technical Support. Annual Technical Support services ordered by Customer
     -----------------
     will be provided under Oracle's Technical Support policies and pricing in
     effect on the date Technical Support is ordered and shall be effective upon
     shipment (or upon Order Form Effective Date for products not requiring
     shipment); first year Technical Support is quoted above, if ordered. A copy
     of Oracle's current Technical Support policies is attached hereto.

4.   Miscellaneous. Oracle shall deliver to the Customer Location, for use in
     -------------
     the Territory, 1 copy of the software media ("Master Copy") and 1 set of
     Documentation (CD-ROM or bound, whichever is generally available) for each
     Program currently available in production release as of the Effective Date
     below for use on the Network; such delivery shall exclude products marked
     with an asterisk (*). For Programs licensed herein, Customer may make
     copies of the Programs, including Documentation up to the number of
     Concurrent Full-Use licenses of Oracle7 licensed on the Order Form between
     Oracle and Customer dated May 8, 1996 and the Customer shall be responsible
     for installation of the software. All fees under this Order Form shall be
     due and payable net 30 days from date of invoice, and shall be
     noncancellable and the sums paid nonrefundable. Customer agrees to pay
     applicable sales/use tax, and media charges. The following shipping terms
     shall apply: FOB Destination, Prepaid and Add. These terms shall also apply
     to any options exercised by Customer. Oracle may refer to Customer as a
     "customer" in sales presentations, marketing vehicles and activities.

C.   OTHER

1.   Additional Designated System. Until 2 years from the Effective Date,
     ----------------------------
     Customer shall have the option to add 2 additional Designated System types
     ("Additional Designated Systems") to this Order Form at no charge, if:
     (i) the Programs licensed herein are available in production release status
     on the Additional Designated System at the time Customer elects to add the
     Additional Designated System; and (ii) Customer has continuously maintained
     Technical Support for such Programs.

     Oracle shall ship to the Customer Location a single Master Copy of the
     Programs licensed herein for the Additional Designated System added. These
     Programs may only be copied and installed in accordance with the terms of
     the Order Form; Oracle has no further shipment obligation other than as
     specified above. Programs licensed herein for use on Additional Designated
     System(s) may not be currently available. Customer has not relied on
     potential availability in entering into the payment obligations in this
     Order Form. Oracle is under no obligation to change current availability.

                                                                          Page 2
<PAGE>
 
 2.  Oracle warrants that its Programs contain the functionality, including the
     time-and-date-related code and internal subroutines, needed for the
     December 31, 1999 millennium date change. Any breach of this warranty is
     subject to the exclusive remedies as set forth in Section 5.3 of the
     Agreement.

 D.  SUBSCRIBER ACCESS

 1.  Oracle Programs. The Programs listed in Section A of this Order Form (i.e.
     ---------------
     Oracle Server Enterprise Edition, Parallel Server Option, and Oracle
     Enterprise Manager Performance Pack) herein shall be collectively known as
     the "Oracle Programs." Customer shall receive an upgrade from Oracle7 to
     Oracle8 at no charge provided Customer has continuously maintained Oracle
     Technical Support Services.

 2.  Subscriber. A "Subscriber" shall be an individual or entity who has
     entered into a written or on-line (e.g. electronic) subscription agreement
     ("Subscription Agreement") with Customer for use of Customer's Prodigy
     Internet service or other Customer online service that provides access to
     the Programs and is a billable account. A "billable account" shall mean an
     account to whom Prodigy issues an invoice. The Subscription Arrangement
     need not refer specifically to "Oracle Programs" but may refer to the
     programs of Customer or its suppliers. Customer shall take reasonable steps
     to ensure that Subscribers are not permitted direct access to the Programs.
     Such Subscription Agreement must provide substantially equivalent terms
     that:

         a.   The Subscriber shall not cause or permit the reverse engineering,
              disassembly or decompilation of the Oracle Programs;

         b.   Title shall not pass to the Subscriber;

         c.   Oracle`s liability for any damages, whether indirect, incidental
              or consequential arising from the use of the Oracle Programs,
              shall be disclaimed to the extent permitted by law; and

         d.   Upon termination of the Subscriber Access Term or the Subscription
              Agreement, whichever is earlier, the Subscriber shall cease using
              the Oracle Programs;

 3.  Subscriber Access. A Subscriber may access the Oracle Programs, remotely
     -----------------
     through telecommunications or fiberoptics. Subscribers may use the Oracle
     Programs solely for the purposes of:

              a.   Authentication

              b.   E-mail

              c.   Storing Subscriber preferences such as frequently visited
                   websites, and Subscriber web-pages. Customer may expand the
                   Content definition by two additional items with Oracle's
                   consent only.

     Neither Customer or a Subscriber may modify the Oracle Programs or use the
     Oracle Programs to create or run Customer's application programs or to
     create tables or reports.

                                                                          Page 3
<PAGE>
 
         [Confidential Materials omitted and filed separately with the
       Securities and Exchange Commission. Asterisks denote omissions.]

 
 4.  In consideration for the payment to Oracle of license and Technical Support
     fees of [**], Customer may allow Subscribers to use the Oracle Programs in
     accordance with Section D.3 above during the Subscriber Access Term
     provided, however, that:

         a.  All use of the Oracle Programs is subject to the terms and
             conditions of the Agreement and this Order Form. If there is any
             conflict between the terms and conditions of the Agreement and this
             Order Form, then the terms and conditions of this Order Form shall
             prevail.

         b.  Subscribers are not permitted to use the Oracle Programs for the
             purposes of developing any application programs or for any other
             purpose not specified in Section D.3.;

         c.  The Subscription Agreements shall include, at a minimum, terms
             equivalent to those set forth in Section D.2 above. Upon Oracle's
             request, Customer shall provide Oracle with a copy of the
             Subscription Agreement used by Customer and

         d.  Customer agrees to indemnify Oracle and hold Oracle harmless from
             all claims, losses, liabilities, and settlement costs, including
             court costs and reasonable fees of attorneys, resulting from any
             claims brought against or incurred by Oracle arising from any use
             or access of the Oracle Programs by Customer's Subscribers.

 5.  Term. The Subscriber rights granted under this Section D of this Order Form
     ----
     shall be effective commencing on the Effective Date and shall continue for
     a period of 22 months from the Effective Date (the "Subscriber Access
     Term"), unless terminated as provided in the Agreement. Such Subscriber
     rights are not perpetual. Any renewal of this Section D shall be in
     accordance with Section D.10 below and shall be subject to renegotiations
     of terms and fees.

     Upon expiration or termination of the Subscriber Access Term or any
     extended term thereof, Customer shall block all Subscribers' access to the
     Oracle Programs. In addition, Customer's license to the Programs shall be
     terminated and Customer shall comply with the terms of Section 4.4 of the
     Agreement. Regardless of the reason for termination or expiration Oracle
     shall have no liability whatsoever to Customer for any damages, including
     damages for loss of prospective profits, anticipated sales, or good will.
     Termination of this Order Form shall not relieve Customer from its
     liability to pay any fees which have accrued to Oracle as of the expiration
     or termination, or which accrue after such expiration or termination.

 6.  Technical Support. Customer is responsible for providing all technical
     -----------------
     support, training and consultation to its Subscribers. Any questions from
     Customer's Subscribers will be referred by Oracle to Customer.

 7.  Termination of Technical Support Services. Customer may terminate
     -----------------------------------------
     Technical Support at any time by notifying Oracle in writing at least
     thirty (30) days before the desired date of termination. Technical Support
     shall be terminated upon receipt of such notice. Upon termination, Oracle
     shall refund the unused portion of Technical Support fees paid by the
     Customer for the licenses for the allocable period for which Technical
     Support is terminated.


                                                                          Page 4
<PAGE>
 
         [Confidential Materials omitted and filed separately with the
       Securities and Exchange Commission. Asterisks denote omissions.]

 
 8.  Additional License and Technical Support Fees. The license and Technical
     ---------------------------------------------
     Support fees listed in Section D.4 above for the Subscriber Access Term,
     are based on Customer retaining an estimated number of Subscribers per
     month as listed on the chart below ("Estimated Subscriber Count"): For the
     purposes of this Order Form, a Subscriber is "retained" by Customer if, at
     the end of a particular month, the Subscriber is entitled to receive any
     on-line services that provide access to the Programs from Customer.


       Month from the          Estimated       Fee per each         Total
       Effective Date      Subscriber Count     Subscriber

           [**]                  [**]              [**]              [**]


                                                                         Page 5

         [Confidential Materials omitted and filed separately with the
       Securities and Exchange Commission. Asterisks denote omissions.]

 
       Month from the           Estimated      Fee per each         Total
       Effective Date       Subscriber Count    Subscriber

           [**]                   [**]             [**]              [**]

     During the Subscriber Access Term, Customer shall report to Oracle monthly,
     the actual number of Subscribers retained by Customer for the preceding
     month ("Actual Subscriber Count"). If during the Subscriber Access Term,
     the Actual Subscriber Count for a month is greater than the Estimated
     Subscriber Count for that month as listed in this Section D.8, such excess
     occurs Customer shall pay to Oracle additional license and Technical
     Support fees for the relevant month; such fees shall be equal to the
     license and Technical Support fee per Subscriber for the relevant month
     (i.e. [**]) multiplied by the difference between the Actual Subscriber Cost
     minus the Estimated Subscriber Count for the relevant month. Customer shall
     not be entitled to any credits or refund if the Actual Subscriber Count
     during any month of the Subscriber Access Term is less than the Estimated
     Subscriber Count listed for that month in the chart above.

 9.  Extended Subscriber Access Term. At the end of the Subscriber Access Term
     -------------------------------
     Customer shall have the option to extend the Subscriber Access Term for 1
     additional year ("Extended Subscriber Access Term"). If Customer exercises
     such option to extend, then Customer and Oracle shall negotiate in good
     faith to determine a combined total license and Technical Support fee per
     Subscriber for the Extended Subscriber Access Term that shall not be
     greater than [**]. After the Extended Subscriber Access Term, if Customer
     and Oracle wish to extend the Subscriber Access Term further, then the
     license and Technical Support fees for such additional extended term shall
     be negotiated at the time of such extension.

 10.  Additional License and Technical Support fees during the Extended
      -----------------------------------------------------------------
      Subscriber Access Term. During the Extended Subscriber Access Term, if
      ----------------------  
      any, Customer shall report to Oracle monthly the actual Subscriber count
      for the preceding month. If during the Extended Subscriber Access Term the
      actual Subscriber count for a month is greater than the estimated
      Subscriber count agreed to by the parties for the relevant month, then for
      each such month in which such excess occurs Customer shall pay to Oracle
      additional license and Technical Support fees for the relevant month. Such
      additional license and



                                                                          Page 6
<PAGE>
 
         [Confidential Materials omitted and filed separately with the
       Securities and Exchange Commission. Asterisks denote omissions.]

 
     Technical Support fees shall be equal to the license and Technical Support
     fee per Subscriber (e.g. [**]) multiplied by the difference between the
     actual Subscriber count minus the estimated Subscriber count for the
     relevant month. Customer shall not be entitled to any credits or refund if
     the actual Subscriber count during any month of the Extended Subscriber
     Access Term is less than the estimated Subscriber count agreed to by the
     parties for any such month.

 11. Exclusive Remedies For Programs. For purposes of this Order Form only,
     -------------------------------
     Section 5.3.A. of the Agreement shall be amended to read as follows: "A.
     For Programs: The correction of Program errors that cause breach of the
     warranty, or if Oracle is unable to make the Program operate as warranted,
     Customer shall be entitled to terminate the Program license and recover the
     fees paid to Oracle for the Program license, and/or cease paying to Oracle
     any fees due to Oracle for the Program license for the remainder of the
     Subscriber Access Term.

Customer and Oracle agree that the terms and pricing of this Order Form shall
not be disclosed without the prior written consent of the other party. This
quote is valid through August 29, 1997 and shall become binding upon execution

In the event Technical Support services lapse or were never originally procured,
a reinstatement fee shall be assessed upon commencement of Technical Support,
such fee shall be subject to Oracle's policies in effect when Technical Support
is ordered. Oracle currently calculates Reinstatement Fees from the date that

Information Customers Need When Calling Support

Before Support can begin work on any problem, information about the nature and
location of the problem is required. Whenever a call is placed to the hotline,
the following information should be provided:

 .    The Customer Support Identification (CSI) number or PC registration number
 .    The area code and phone number listed under the CSI number 
 .    Operating system (including version) on which Oracle Programs are installed
 .    The Oracle product component and its version number the call concerns.
     Support questions involve product components -- that is, constituent parts
     of an Oracle product. For example, with the ORACLE kernel, Customer
     receives components such as RDBMS, IMP, EXP, SQL*Loader and SQL*Forms.
 .    The relevant Program version(s)
 .    Any Program error number that appeared
 .    Brief description of the problem
 .    Severity of the problem. Oracle Worldwide Support classifies problems
     according to how they impact the Customer's business. See list below for
     explanation of Technical Assistance Request (TAR) Severity Levels.


Technical Assistance Request (TAR) Severity Levels

The chart below lists standard Technical Assistance Request Severity Levels.
Oracle Worldwide Customer Support responds to TARs based on Severity Level.

Severity Level
- --------------

Severity 1 
Critical Business Impact
Customer's work, regardless of the environment or product usage, is stopped or
so severely impacted that the customer cannot reasonably continue to work.

Severity 2
Severe Business Impact 
Customer's work is continuing (not stopped) however there
is a serious impact on the customer's productivity and/or service levels.

Severity 3
Minor Business Impact
The customer's work regardless of the environment or product usage, has minor
loss of services or resources.



Severity 4
No Business Impact
Customer is in full working mode - there is no work being impeded at the time -
information is requested but has no impact on the operation of the products.

TARs are logged and tracked in Support's Support Systems. Response will be given
to the Customer by telephone and logged directly into the problem-tracking
system. The Customer may dial-in to track the progress of their TAR at any time.

                                Subject to Change



Support's response may include a written response, patch tape, supplementary
documentation, a temporary means of circumventing the problem pending a new
release, or other correctional aids.


Customer CPU Support Identification (CSI) Number

Customers shall receive a CSI Number upon purchasing Oracle Technical Support
services.

The CSI number identifies the Customer with respect to the following
information:

 .    Company Name and Address
 .    Product Set and Version
 .    Support Level and Duration
 .    Operating System
 .    Technical Contact Information

Worldwide Customer support uses the CSI number to identify the Customer's
Support contract when a Customer calls the Support Hotline or uses dials-in
access.


Technical Support Liaison 
("Technical Contact")

Customers shall designate one (1) primary and two (2) backup Customer employees
("Technical Contacts") to serve as liaisons with Oracle Worldwide Customer
Support. The designated "Technical Contact" is the sole liaison between
technical support and Customers for all product support and shall be based on
the Customer site. Customer may elect to add Technical Contacts for an
additional fee.

To assure uninterrupted Technical Support service, customers must notify Client
Relations at (415) 506-1500, option 9, whenever Technical Contact
responsibilities are transferred to another individual.

Updates

"Update" means a subsequent release of the Program which Oracle generally makes
available for Program licenses at no additional license fee other than media and
handling charges, provided Customer has ordered Technical Support for such
licenses for the relevant time period. Update shall not include any release,
option or future product which Oracle licenses separately.


Terms of Support

Oracle Worldwide Customer Support's technical assistance is limited to licenses,
products, and platforms that are fully supported and to problems which are
demonstrable in the current release of the licensed program, running unaltered
on the proper hardware configuration. Current release information is posted
on-line.

Technical Support for older versions of Oracle products or for non-Oracle
products is subject to additional fees.

These Technical Support policies are Oracle's current policies and are subject
to change at Oracle's discretion.


Termination

Customer may terminate technical support at any time by notifying Oracle in
writing at least thirty (30) days before the desired date of termination.
Technical Support shall be terminated upon receipt of such notice. On
termination, Oracle shall refund the unused portion of technical support fees
paid by the Customer for the licenses for the allocable period for which
technical support is terminated.

This Payment Plan Agreement is entered into by Customer and Oracle Credit
Corporation ("OCC") to provide for the payment of the System Price specified in
a Payment Schedule on an installment basis. Each Payment Schedule shall specify
the Software and other incidental products and services (which items, together
with any upgrade, transfer or substitution of the foregoing, collectively are
the "System"), the System Price, and the Order and Agreement covered by the
Payment Schedule. Each Payment Schedule shall incorporate the terms and
conditions of this Payment Plan Agreement (together referred to as a "PPA"). The
System shall be licensed or provided by Oracle directly pursuant to the terms of
the Order and Agreement. Except as otherwise provided under this PPA, Customer's
right and remedies under the Order and Agreement, including Oracle's warranty
and refund provisions, shall not be affected.

1. PAYMENT SCHEDULE: Customer agrees to pay OCC the Payment Amounts in
accordance with this PPA, with each payment due and payable on the applicable
Due Date. If full payment of each Payment Amount and other amounts payable is
not received by OCC within 10 days of each Due Date, Customer agrees to pay to
OCC interest on the overdue amount at the rate equal to the lesser of one and
one-half percent (1.5%) per month, or the maximum amount allowed by law. Unless
stated otherwise, Payment Amounts exclude any applicable sales, use, property or
any other tax allocable to the System, Agreement or any PPA ("Taxes"). Any
amounts or any Taxes payable under the Agreement which are not added to the
Payment Amounts due under this PPA are due and payable by Customer, and Customer
shall remain liable for any filing obligations. Customer's obligation to remit
Payment Amounts to OCC or its assignee in accordance with this PPA is absolute,
unconditional, noncancellable, independent, and shall not be subject to any
abatement, set-off, claim, counterclaim, adjustment, reduction, or defense for
any reason, including but not limited to, any termination of any Agreement, or
performance of the System.

2. ASSIGNMENT: Customer hereby consents to OCC's assignment of all or a portion
of its rights and interests in and to this PPA to third-parties ("Assignee").
OCC shall provide Customer notice thereof. Customer and OCC agree that Assignee
shall not, because of such assignment, assume any of OCC's or Oracle's
obligations to Customer. Customer shall not assert against Assignee any claim,
defense, counterclaim or setoff that Customer may have against OCC or Oracle.
Customer waives all rights to make any claim against Assignee for any loss or
damage of the System or breach of any warranty, express or implied, as to any
matter whatsoever, including but not limited to the System and service
performance, functionality, features, merchantability or fitness for a
particular purpose, or any indirect, incidental or consequential damages or loss
of business. Customer shall pay Assignee all amounts due and payable under this
PPA, but shall pursue any claims under any Agreement against Oracle. Except as
provided for a Customer default below, neither OCC nor its Assignees will
interfere with Customer's quiet enjoyment or use of the System in accordance
with the Agreement's terms and conditions.

3. DEFAULT; REMEDIES: Any of the following shall constitute a Default under this
PPA: (i) Customer fails to pay when due any sums due under any PPA: (ii)
Customer breaches any representation or fails to perform any obligation in any
PPA; (iii) Customer materially breaches or terminates the license relating to
the Software; (iv) Customer defaults under a material agreement with Assignee;
or (v) Customer becomes insolvent or makes an assignment for the benefit of
creditors, or a trustee or receiver is appointed for Customer or for a
substantial part of its assets, or bankruptcy, reorganization or insolvency
proceedings shall be instituted by or against Customer.

In the event of a Default that is not cured within thirty (30) days of its
occurrence, OCC may; (i) require all outstanding Payment Amounts and other sums
due and scheduled to become due (discounted as the lesser of the rate in this
PPA or five percent (5%) per annum simple interest) to become immediately due
and payable by Customer: (ii) pursue any rights provided under any Agreement,
including terminating all of Customer's rights to use the System and related
services; and (iii) pursue any other rights or remedies available by law or in
equity. In the event OCC institutes any action for the enforcement of the
collection of Payment Amounts, there shall be due from Customer, in addition to
the amounts due above, all costs and expenses of such action, including
reasonable attorneys' fees. No failure or delay on the part of OCC to exercise
any right or remedy hereunder shall operate as a waiver thereof, or as a waiver
of any subsequent breach. All remedies are cumulative and not exclusive Customer
acknowledges that upon a default under this PPA, no party shall be required to
license, lease, transfer or use any Software in mitigation of any damages
resulting from Customer's default.

4. CUSTOMER'S REPRESENTATIONS AND COVENANTS:
Customer represents that, throughout the term of this PPA, this PPA has been
duly authorized and constitutes a legal, valid, binding and enforceable
agreement of Customer. Any transfer or assignment of Customer's rights or
obligations in the System, or under the Agreements or this PPA shall require
Oracle's and Assignee's prior written consent. A transfer shall include a change
in majority ownership of Customer. Customer agrees to promptly execute any
ancillary documents and take further actions as OCC or Assignee may reasonably
request, including, but not limited to, assignment notifications, acceptance
certificates, certificates of authorization, registrations, and filings.
Customer agrees to provide OCC or Assignee copies of Customer's balance sheet,
income statement, and other financial reports as OCC or Assignee may reasonably
request.

5. MISCELLANEOUS: This PPA shall constitute the entire agreement between
Customer and OCC regarding the subject matter herein and shall supersede any
inconsistent terms set forth in the Order, Agreement or any related agreements,
Customer purchase orders and all prior oral and written understandings. If any
provision of this PPA is invalid, such invalidity shall not affect the
enforceability of the remaining terms of this PPA. Customer's obligations under
this PPA shall commence on the Effective Date specified therein. Except for
payment terms specified in this PPA, Customer remains responsible for all the
obligations under each Agreement. Each Payment Schedule, and any changes to a
PPA or any related document, shall take effect when executed by 0CC. This PPA
shall be governed by the laws of the State of California and shall be deemed
executed in Redwood Shores, CA as of the PPA Effective Date.

and Sections 6.5, 6.10, 6.11 and 6.12 and all other rights and obligations of
the Company and Provider herein shall only become effective as of the end of the
Transition Period (as hereinafter defined).


Part 1 - General
- --------------------------------------------------------------------------------

1.1      Definitions

         "Equipment" is a machine, including its features, conversions,
         upgrades, elements, or accessories, or any combination of them. The
         term "Equipment" includes SplitRock Equipment and any non-SplitRock
         Equipment we provide to you, but excludes Programs.

         "Materials" are work products (such as programs, program listings,
         programming tools, documentation, reports, and drawings) that we may
         deliver to you during a project. The term "Materials" does not include
         Programs.

         "Product" is a Program or Equipment.

         "Program" is the following, including features and any whole or partial
         copies:

            1.  machine-readable instructions;

            2.  a collection of machine-readable data, such as a data base; and

            3.  related licensed materials, including documentation and
                listings, in any form.

            The term "Program" includes a SplitRock Program and any
            non-SplitRock Program that we may provide to you. The term does not
            include licensed internal code or Materials.
<PAGE>
 
         "Services" as used herein describes the network services (not to
         include satellite) we will provide, as more particularly described in
         Section 6.1. In addition, any new service you request or additional
         service you request, not already contemplated by this Agreement, and
         that we agree to provide is not the subject of this Agreement until the
         terms, conditions and prices of such service shall be confirmed in
         Transaction Documents. In addition, Services provided to you hereunder
         shall include reports, surveys and analysis reasonably required to
         fulfill the purposes of this Agreement, and shall not be subject to any
         additional charge.

         "Subscriber" is any user authorized to access basic Prodigy Classic or
         basic Prodigy Internet (as they currently exist), regardless of whether
         such user actually uses your services in any month or regardless of
         whether or not you receive payment from that user.

         "Subscriber Comic" shall mean the total number of Subscribers, subject
         to the limitations in this definitional paragraph. For Prodigy Classic,
         multiple User Identifications associated with one Subscriber will count
         as one Subscriber in the Subscriber Count. For Prodigy Internet,
         multiple User Identifications associated with one Subscriber will count
         as one Subscriber in the Subscriber Count, provided only one such User
         Identification per Subscriber can access the Service at any one time. A
         Subscriber to both Prodigy Classic and Prodigy Internet under the
         "Prodigy Combo Plan" will count as one Subscriber in the Subscriber
         Count. Any Subscriber who is not capable of accessing the Service shall
         not be counted in the Subscriber Count.

         "System" is the Services and Products we provide together under this
         Agreement that we identify to you as a System, which identification is
         in writing.

         "Transition Period" is the period from July 1, 1997 until the earlier
         of (i) December 31, 1997 or (ii) on the effective date of a notice from
         Provider stating that it intends to terminate the Transition Services
         Agreement which effective date may only be the last day of a calendar
         month.

         "User Identification" is a code or codes which enable authorization or
         access to programs, data or equipment through a Service.


 1.2     Agreement Structure 

         Attachments

         Some Services and Products have terms in addition to those we specify
         in this Agreement. We will provide the additional terms in documents
         called "Attachments," which are also part of this Agreement.

         Transaction Documents

         For each business transaction, we will provide to you the appropriate
         "Transaction Documents" before the transaction occurs that confirm the
         details of the transaction, which Transaction Documents shall nor be
         effective against or in favor of either party, unless and until each
         party agrees to each appropriate set of Transition Documents in
         writing.

         Conflicting Terms
<PAGE>
 
         If there is a conflict among the terms in the various documents, those
         of an Attachment prevail over those of this Agreement. The terms of a
         Transaction Document prevail over those of both the Attachments and
         this Agreement.

         Your Order

         You may order a Service or Product in writing, including a request
         written on paper and delivered to us and a request sent via facsimile
         to us.

         Our Acceptance of Your Order

                  A Service or Product becomes subject to this Agreement when we
         accept your order by sending you a Transaction Document which accepts
         expressly and precisely the terms of the order.

         Your Acceptance of Additional Terms

         You accept the additional terms in an Attachment or Transaction
         Document by signing it.


1.3      Electronic Communications

         You and we may communicate with the other by electronic means for
         information purposes only, such as through electronic or Prodigy Mail.
         Any electronic communication must be followed by written confirmation
         or telecopied in order to be binding on either party. Documents which
         include handwritten signatures may be transmitted by telecopier, and
         shall be deemed binding without the need for original signatures.
         Nevertheless, original signature copies are preferred.


1.4      Prices

         The following are the bases on which we may require the amount payable
         for a Service or Product to be paid, with an example of each:

         1.   one-time (Service installation charges);

         2.   recurring (a periodic charge for Services);

         3.   a combination of both (an initial charge and a monthly license
              charge for a Program); or

         4.   usage (network traffic charges).

         We will specify the amount and basis for the particular Service or
         Product. If additional Products or Services are added, the prices will
         be set forth in a Transaction Document. Except as herein provided
         specifically, no additional charges shall be imposed or incurred for
         Services which we are obligated to provide under this Agreement.


 1.5     Payment and Taxes 

         You shall pay:
<PAGE>
 
         1.   usage and recurring charges according to Section 6.5.

         2.   all other charges when or after you incur them.

         Amounts due are payable as we specify in the invoice which invoice
         shall be consistent with the conflict hierarchy set forth in Section
         1.2, Conflicting Terms, or, with respect to dial up network services,
         as provided in Section 6.5. You agree to pay accordingly. You agree to
         pay any tax on the Services we provide to you. You are responsible for
         personal property taxes for each Product that you purchase and each
         Program that you license from the date we ship it to you or otherwise
         make it available to you. "Taxes" as used in this Agreement shall not
         include any FCC charges or other charges payable to any government
         organization other than a taxing authority, all of which we shall pay.


 1.6     Patents and Copyrights

         For purposes of this Section only, the term "Product" includes
         Materials alone or in combination with Products we provide to you as a
         System.

         If a third party claims that a Product we provide to you infringes that
         party's patent or copyright, we will defend you against that claim at
         our expense and pay all costs, damages, and attorney's fees that a
         court finally awards, provided that you:

         1.   promptly notify us in writing of the claim; and

         2.   allow us to control, and cooperate with us in, the defense and any
              related settlement negotiations. At your option and at your cost,
              you may retain counsel to advise you as you work with us.

         If such a claim is made or appears likely to be made, we will take
         reasonable steps, and you agree to permit us to do so, to enable you to
         continue to use the Product, or to modify it, or replace it with one
         that is at least functionally equivalent. If we determine that none of
         these alternatives is reasonably available, you agree to return the
         Product to us on our written request and we may terminate the affected
         Service at no further charge to you, in which case we will refund to
         you the unused prorata portion of any advance payments for the Service
         and/or the Product.

         YOU AGREE THAT YOUR RIGHTS, AS PROVIDED BY THIS SECTION 1.6, REGARDING
         ANY CLAIM OF INFRINGEMENT ARE LIMITED AND THE REMEDIES IN THIS SECTION
         WILL BE YOUR SOLE AND EXCLUSIVE REMEDY FOR ANY SUCH CLAIM.




         Notice of Infringement

         All notices of patent or copyright infringement permitted or required
         by this Agreement will be in writing and will take effect upon receipt.

         Claims for Which We are Not Responsible
<PAGE>
 
         We have no obligation regarding any claim to the extent it is based on
         any of the following:


         1.   your modification of a Product, or a Program's use with equipment
              and programs other than the Equipment and Programs with which the
              Program is designed to operate:

         2.   the combination, operation, or use of a Product with any product,
              data, or apparatus that we did not provide unless we had written
              notice and acknowledged in writing receipt of notice that the
              intended use of the Product was for a use with a product, data, or
              apparatus we did not provide; or

         3.   infringement by a non-SplitRock Product alone, as opposed to its
              combination with Products we provide to you as a System.


 1.7     LIMITATION OF LIABILITY

         Circumstances may arise where, because of a default on our part or
         other liability, you are entitled to recover damages from us. In each
         such instance, regardless of the basis on which such party is entitled
         to claim damages, we are liable only for:

         1.   payments referred to in our patent and copyright terms described
              above;

         2.   bodily injury (including death), and damage to real property and
              tangible personal property; and

         3.   the amount of any other actual loss or damage, in excess of
              $100,000 or the charges (if recurring or usage, 12 months' charges
              apply) for the Service or Product that is the subject of the
              claim.

              This limit also applies to any of our subcontractors, agents and
              Program developers. It is the maximum for which we, our
              subcontractors, agents and program developers are collectively
              responsible.


         Items for Which Neither Party is Liable

         Under no circumstances are either party or its subcontractors, agents
         or Program developers liable for any of the following:

         1.   third-party claims against the other party for losses or damages
              (other than those under the first two items listed in 1.7 above)
              except for willful acts or acts of gross negligence;

         2.   loss of, or damage to, records or data except for any actual loss
              or damage willfully and intentionally caused by the other party or
              caused by gross negligence, subject to the limitation contained in
              Section 1.7(3) above; or

         3.   economic consequential damages (including lost profits or savings)
              or incidental damages, even if either party is informed of their
              possibility.
<PAGE>
 
         EACH PARTY AGREES THAT ITS RIGHTS ARE LIMITED BY THIS SECTION 1.7. THAT
         THE LIMITATIONS PROVIDED HEREIN ARE FAIR AND EQUITABLE, AND EACH PARTY
         HEREBY WAIVES ANY RIGHT OR REMEDY IT MAY HAVE FOR THE RECOVERY OF ANY
         OTHER DAMAGES.


 1.8     Your Additional Rights

         You may have additional rights under certain laws (such as consumer
         laws) which do not allow the exclusion of implied warranties, or the
         exclusion or limitation of certain damages. If these laws apply, our
         exclusions or limitations may not apply to you.


 1.9     Changes to and Termination of Services

         If a third party claims that a Product we provide as part of a Service
         infringes a patent or copyright, we reserve the right to first
         substitute a different Product, or alternatively to terminate the
         Service effective immediately.


 1.10    Geographic Scope

         All of your rights, all our obligations, and all licenses are valid
         only in the United States, including Hawaii and Alaska.


 1.11    Governing Law

         any action shall be brought in the state or federal courts located in,
         and any arbitration proceeding shall be located in, the domicile of the
         party who is an initial defendant or the party upon whom an initial
         demand for arbitration is served.

Part 6 - SplitRock Services
- --------------------------------------------------------------------------------

6.1      Description

         We will provide you network services consisting of the following
         components:

         .  Dial access network as described in Section 6.1.1

         .  ATM backbone network as described in Section 6.1.2

         .  Regional Servers connectivity as described in 6.1.3

         .  Network Management and Proxy Servers as described in Section 6.1.4

         6.1.1   Dial Access Network

         We will provide to you dial access for data transport for your
         Subscribers as described in this Agreement as a "Service". We will
         provide this Service to you in all locations in which, on the effective
         date of this Agreement, such dial access service already exists. You
         agree to provide to us a list of current dial access locations, which
         list shall be Appendix "A" to this Agreement. We may substitute a new
         site for an existing location upon 30 days prior notice of change, with
         60 days simultaneous usage. You may request new sites to exceed an 80%
         coverage, by population, for local dial access; but we will not be
         obligated to provide dial access Service in any new dial access
         location with usage in any month of less than 5,000 dial hours unless
         we review the location for the new site and approve the creation of a
         new site at such location, in our sole discretion. We can modify the
         site coverage only with your permission, unless the modification is for
         a substitution of existing coverage, in which case we do not need your
         permission. Any new sites added by us for Services will be available to
         you if you choose to use them.

         The data traffic dial access Service shall include the receipt of
         inbound data dial traffic from your Subscribers and the routing of such
         traffic to another Subscriber, to a proxy server, to a regional server,
         to your data center at Yorktown or to the selected Internet Network
         Access Points ("NAP"). We will not support initiating a call to another
         Subscriber's telephone.

         We shall, in our sole discretion, decide the number of dial ports we
         provide to serve each site, as well as the method we use to provide
         Service to each site provided the grades and standards of service as
         set forth in this Agreement are met. Examples of methods we may use to
         provide this Service include:

         .  a physical site presence with modem ports; or
         .  a virtual presence using call forwarding or a foreign exchange.

         All new access equipment provided by us will have speed capacity with
         respect to backbone access, and with respect to Subscriber access,
         consistent with the service that can and will be provided from that
         site. For example, we will not install equipment with a speed higher
         than the existing line infrastructure can support, except we
         acknowledge that we shall install 56K capable bps modems, although
         current FCC regulations prohibit transmission at speeds in excess of
         53K bps, and, other conditions beyond our control may decrease the
         actual connection speed.

         Specifically identified protocols to be supported: include Serial Line
         Internet protocol (SLIP), Prodigy Link Level Protocol (PLLP), and
         Point-to-Point Protocol (PPP).
<PAGE>
 
We shall be responsible for:

 .    inbound communication facilities (such as hunt groups, measured business
     lines or DID trunks);

 .    modem hardware including ports and chassis; and

 .    network equipment and communications facilities to transport traffic from
     our dial site to other sites, to your data center at Yorktown and the seven
     NAPs.

We shall transport the dial data traffic to you via TCP/IP over ATM. We will not
change the terms or conditions of a Service without your approval, which you
agree will not be unreasonably withheld.


6.1.2   ATM Backbone Network

The SplitRock ATM backbone network will be operational on or before December 31,
1997 and will be based on the Yurie LDR200/50 ATM switches or similar ATM
switches. This network is based on ATM switches, supporting TCP/IP protocol for
Prodigy Classic and Prodigy Internet services. Prodigy Classic transmission
which requires SNA will be encapsulated as TCP/IP. Each dial access site will be
upgraded with a LDR200, LDR50 or similar ATM switch. A backbone transmission
facility based on ATM protocol will interconnect the dial access sites to
Yorktown, New York. Since the Yurie ATM switches use standard ATM protocol, the
interconnections can be a mixture of FT1 TI, T3 and OC-3 or publicly available
switched ATM services.

Effective July 1, 1997 but subject to the Transition Services Agreement, we
shall also provide, maintain and manage sufficient bandwidth connections to
Yorktown, New York to support the Service Level Objectives in Section 6.2. The
transmission facilities may be DS-3, OC-3 or other appropriate transmission
services available at the time. The transmission facilities will be terminated
by a LDR2OO and Centillion C100 combination or equivalent provided by us at your
Yorktown facility. The transmission facilities will be diversely routed and
fully separated and connect to you via selected routers. The two SplitRock C100s
will connect to existing Prodigy 6611 or equivalent routers, which support the
Prodigy internal LAN at Yorktown.

The Equipment we provide at Yorktown will be installed on your premises solely
for our use in providing our Services. This Equipment is provided under the
terms specified in the Section "Equipment We Provide."

In addition, at locations selected by us agreed, we will provide interconnection
of the network to the Internet via DS3 to suitable NAPs. This will provide
bandwidth between the NAP and Yorktown as well as between the NAP and the dial
up user. We will have the sole right to select the choice of the NAP provider at
each location. You will be responsible for complying with all protocol
requirements for layer 3 and above as set forth by the NAP providers that we
select.

6.1.3   Regional Servers

You may provide, maintain and manage regional servers at sites determined by you
which are to be geographically dispersed and co-located at our network hub
sites; such equipment is limited to
<PAGE>
 
that which may only be installed in one standard 19" rack per site ("Regional
Servers"). You shall provide, maintain and manage diagnostic equipment,
connection equipment that you may use to connect to us and associated analog
phone lines which you may use to manage your Regional Servers. In addition, you
shall provide the electric power cables and the equipment connection cables for
the equipment you provide, including those cables, required to connect your
equipment to our network equipment. You also agree to comply with all safety
requirements at each site. Each Regional Server will be EtherNet connected to
our network. Neither we nor any other customer of ours shall use your Regional
Servers for any purpose except to support Prodigy Classic and Prodigy Internet.
We shall provide you with access to our sites for purposes of maintaining,
upgrading and servicing these Regional Servers at no additional cost to you.

You are responsible for separately procuring from us the upstream connection
from the Regional Server. The upstream connection is defined as the network
facilities used to transport traffic from the Regional Server to locations other
than the source dial node (such as Yorktown or the Internet). Cost for such
services will be as provided in Section 6.5.2 section 2 of this Agreement

The Regional Servers will not be included in the service level objectives, as
provided in Section 6.2.

6.1.4   Network Management and Proxy Servers


          Network Management

          We will maintain TINA until we replace it with a new network
          management system which encompasses all TINA functions. You will make
          available to us the mainframe computer resources necessary to run TINA
          for the purpose of managing the network at no cost to us. We will
          provide you read only terminal access to TINA and any other network
          management system used by us so that you can determine the operational
          status of any modem or network component.

          Proxy Servers

          We will assume your existing Unix servers and all hardware and
          software maintenance costs as they directly relate to proxy functions.
          These servers will be placed at our hub and peering sites. We will
          also provide for a fee additional new Unix based servers at hub sites
          when needed and requested by you. Unix based servers will not be
          supported at all POP sites.

          We intend to use Windows NT based servers for the POP sites and for
          future hub sites for the proxy server functions.


Service Level Objectives

We will have four service level objectives for both Prodigy Internet and Prodigy
Classic:

1.        Site Dial Grade of Service (SDGS) objective of P.01 during the peak or
          busiest hours of the day (We will use your algorithms in effect as of
          June 23, 1997 for purposes of measuring the SDGS and Grade of
          Service);
<PAGE>
 
       2.      Site System Availability (SSA) objective of 99.5%;

       3.      Overall System Availability (OSA) objective of 99.5%; and

       4.      Transit Delay (TD) objective average of 100 milliseconds or less
               95% of the time and 150 milliseconds or less 99% of the time,
               however, TD objective average for Alaska and Hawaii is 300
               milliseconds. (We will use your algorithms in effect as of June
               23, 1997 for purposes of measuring the TD and Grade of Service)

NOTE:  A P.01 Grade of Service means that no more than 1% of calls are denied
- -----  access during the peak busy hour of the weekly measured period. A P.03
       Grade of Service means that no more than 3% of calls are denied access
       during the peak busy hour of the weekly measured period.

       We shall measure each of the objectives, other than SDGS, on a monthly
       basis and shall provide you with a report of such measured objectives by
       the 10th business day of the following month, unless otherwise agreed
       between the parties.

       6.2.1   Site Dial Grade of Service (SDGS) Objective

               We shall measure and report the weekly Site Dial Grade of Service
               for each site. If the SDGS, measured weekly, falls below P.03 for
               a site in two consecutive weeks, we shall have four additional
               weeks to improve the performance. If, during this four week
               period, the measured SDGS is not improved above P.03 with the
               intent to meet the P.01 objective, then we shall provide you a
               credit of $1,500.00 for each four week period thereafter for that
               site until such time as the measured SDGS is improved above P.03.
               Except for your right of termination as provided for in Section
               6.7.1, this is your sole remedy for our failure to meet the SDGS
               objective.

               Grade of Service reductions which are caused by, related to or
               extended as a result of your actions, or Force Majeure shall not
               be considered in the estimation of the monthly SDGS.

               Should you supply an invalid forecast (see Section "Forecasts"),
               then the SDGS objective will not be applicable for that period.


       6.2.2   Availability Objectives

               The components of the availability objective calculations shall
               include the components provided by us. The OSA rate and the SSA
               rate shall be represented as a percentage of the time the
               components are actually available, as compared to the scheduled
               time of availability.

               The SSA shall be defined as the monthly availability of the
               Service components for a single site including the modem and
               server components at the site, and network connections from the
               site to Yorktown. We shall measure and report the monthly site
               availability, and deliver such report to you no later than the
               10th business day after the month of resting.
<PAGE>
 

 
               We will measure and report site availability by sending a 56 byte
               message, called a sample ping, to the modem chassis and to the
               servers from a SplitRock network monitor in Yorktown on a
               periodic basis, but no less than every 10 minutes. The ping
               sampling interval is subject to change over time but in no event
               shall it be more than 30 minute intervals. If a positive response
               is received to the ping, then the site is considered available
               for that ping period. We will issue one retry (or effectively do
               the retry using another function) if an initial negative response
               is received. If a positive response is received on the retry then
               the site is considered available for that ping period. If a
               negative response is received from the initial ping and the
               retry, then the site is considered unavailable for that ping
               period.

               The SSA rate calculation shall be;

               .   the Total Scheduled Minutes of Availability for the site;
               .   minus the Total Unscheduled Outage Minutes for the site;
               .   divided by the Total Scheduled Minutes of Availability for
                   the site.
<TABLE> 

         <S>                                         <C> 
         (Total Scheduled Minutes of Availability) - (Total Unscheduled Outage Minutes) 
         ------------------------------------------------------------------------------
         (Total Scheduled Minutes of Availability)
</TABLE> 

               The Total Scheduled Minutes of Availability for a site is defined
         as the total minutes in the measurement time period minus the total
         minutes of outages which are not due to unscheduled outages during the
         measurement time period.

               Total Unscheduled Outage Minutes include outages due to
         telecommunication facilities (carrier outages), loss of electrical
         power, hardware, operations, software and design problems except for;

               1.  scheduled network maintenance and scheduled outages;

               2.  outages caused by, related to, or extended as a result of
                   your actions; and

               3.  outages due a Force Majeure event.

               If the SSA rate for a specific site, measured monthly, falls
below 98.5% we shall take immediate and necessary action to improve the
performance. If the measured SSA rate for the site is not improved above 98.5%
with the intent to meet the 99.5% objective within the next two months, we shall
provide you a credit of $1,500.00 for each month thereafter for that site until
such time as the measured SSA rate is improved above 99.5%. Except for your
right of termination provided for in Section 6.7.1, this is your sole remedy for
our failure to meet the SSA objective.

               The OSA objective is defined as the combined availability of the
Service components, including the modem and server components, and network
connections to Yorktown. The OSA rate shall be an average of all the SSA rates.
We shall measure and report the monthly OSA,

               If the OSA rate, measured monthly, falls below 98.7% we shall
take immediate and necessary action to improve the performance. If the measured
OSA rate is not improved above 98.7% with the intent to meet the 99.5% objective
within the next two months, we shall provide you a credit of $25,000.00 for each
month thereafter until such time as the measured OSA rate is improved above
<PAGE>
 

 
98.7%. Except for your right of termination provided for in Section 6.7.1, this
is your sole remedy for our failure to meet the OSA objective.

            We shall be allowed a system-wide weekly maintenance window. The
weekly maintenance window shall occur initially Sunday mornings from 3:15 to
4:45 Eastern time. This initial period may be changed upon your prior written
consent. Additionally, there shall be an allowance for scheduled outages at each
site for us to perform maintenance/upgrade work: allowing each site two outages
annually each up to three hours in duration. We shall provide you with advance
notice of sites scheduled for upgrade/maintenance activity, and we shall use
reasonable efforts to schedule such upgrade/maintenance activity for a time
other than 5 pm to midnight, local site time.

            We shall review anticipated changes in the network maintenance
window with you. You and we shall cooperate to accommodate a necessary change in
the network maintenance window and the business impact on you.

            We shall not be precluded from performing unscheduled maintenance as
we may deem necessary. In such instances we will use reasonable efforts to
notify you at least 48 hours in advance. For purposes of the SSA and OSA rate
calculations, these will be considered unscheduled outages.

          6.2.3    Transit Delay

                   The TD is represented as the actual time for a 56 byte
message, called a sample ping, to travel round trip between two specific routers
in the network under normal prime time conditions.

                   Using the sample ping referred to in Section 6.2.2, we will
measure the TD on a periodic basis, but no less than every 10 minutes. The ping
sampling interval is subject to change over time but in no event shall exceed 30
minutes. We will average all the samples in a given month to determine the
overall average TD, and will report that to you.

                   If we fail to meet the monthly TD objectives, you will notify
us in writing. If we continue to fail to meet the TD objectives for two months,
then we shall provide you a credit of $25,000.00 for each month thereafter until
such time as the measured TD meets the objectives. Except for your right of
termination provided for in Section 6.7.1, this is your sole remedy for our
failure to meet the TD objectives.

                   In an instance where the monthly forecast for 20% of the
sites is invalid, then the TD objective shall not be applicable for that period.


6.3       Our Other Responsibilities 

          We will:

          1.       provide you with a number for your operations group or
customer service group to contact our help desk support, which shall be
available 24 hours a day, 7 days a week, and staffed adequately to handle all
inquiries within 60 seconds of receipt;

          2.       provide you with standard monthly, or in the case of SDGS
weekly, reports that we produce that are related to the Services provided under
this Agreement, including reports describing the results of the tests for each
of SDGS, SSA, OSA and TD, and reports relative to availability and traffic
<PAGE>
 
         [Confidential Materials omitted and filed separately with the
       Securities and Exchange Commission. Asterisks denote omissions.]

 
statistics within ten days of the end of the immediately preceding month, which
reports will show by site, the total connect hours, time of peak busy hour per
site, average peak busy hour percentage and distribution of traffic by hour of
day;

          3.   provide you with a monthly report detailing the status of network
upgrades and expansions within ten day of the end of the immediately preceding
month;

          4.   maintain the components, programs, equipment and materials we
provide under this Agreement; and

          5.   provide you with read only terminal access to our network
management system so you can verify operational status of all network modems and
components.


6.4       Your Other Responsibilities 

          You agree:

          1.   to be responsible for supporting your Subscribers directly
through your help desk. Your operations group or customer service group will
contact our help desk in regard to any reported problems with the Service being
provided by us;

          2.   to be responsible for ensuring that your software can and will
log-off each Subscriber after no activity by each Subscriber for 30 minutes
("Time Out Function");

          3.   to be responsible for ensuring that for Prodigy Internet Services
your software will not allow multiple User Identifications associated with any
Prodigy Internet Subscriber to gain simultaneous access to the Services
("Simultaneous Prohibition Function"); and

          4.   upon written request by us audit each of the Time Out Function
and Simultaneous Prohibition Function up to five audits per each 12 month
period. Within 15 days of receiving a written audit request you will delivery a
written audit report to us. If the audit shows noncompliance with the Time Out
Function or Simultaneous Prohibition Function, as the case may be, the Maximum
Monthly Usage Charge (as provided in Section 6.5.1) shall not be applicable to
any time period from the date of the last audit showing compliance until the
date you cure such noncompliance.


6.5       Charges 

6.5.1     Monthly Usage Charges

          With respect to usage, you agree to pay us for the Services based on
the total number of monthly connect hours of your Subscribers times the
applicable rate per hour in the following schedule (the "Hourly Usage Charge"),
subject to the Maximum Monthly Usage Charge (upper limit) and Minimum Monthly
Usage Charge (lower limit) described below:

          Hourly Usage Charge Rate Schedule:

                   July 1, 1997 through December 31, 1997          [**] per hour
                   January 1, 1998 though December 31, 1998        [**] per hour
<PAGE>
 
         [Confidential Materials omitted and filed separately with the
       Securities and Exchange Commission. Asterisks denote omissions.]

 
                   All subsequent years                            [**] per hour

          Maximum Monthly Usage Charge: You agree to provide to us each month
the Subscriber Count for such month (by price plan) as of the last day of each
month, by the fifth day of the next month. We will use the Subscriber Count as
the basis for calculating the Maximum Monthly Usage Charge for such month. For
any month in which the average monthly connect hours per Subscriber (total
connect hours divided by the Subscriber Count) does not exceed 30 hours, the
Maximum Monthly Usage Charge you will pay is equal to [**] times the Subscriber
Count for such month. If the average monthly connect hours per Subscriber in
any month exceeds 30 hours, then, in addition to the Maximum Monthly Usage
Charge, we shall invoice you, and you agree to pay us an additional amount equal
to (a) [**] per hour times (b) the number of average hours (or any portion
thereof) in excess of 30 hours times (c) the Subscriber Count for such month. In
the event that the Maximum Monthly Usage Charge does not apply, as described in
Section 6.4 or in the previous sentence, you will pay us the greater of the
applicable Hourly Usage Charge or the Minimum Monthly Usage Charge for such time
period of noncompliance.

          Minimum Monthly Usage Charge:

          $3,000,000 per calendar month for the period from July 1, 1997 through
          June 30, 1998; 
          $3,500,000 per calendar month for the period from July 1, 1998 through
          June 30, 1999;
          $4,000,000 per calendar month for the period from July 1, 1999 through
          June 30, 2000;
          $4,500,000 per calendar month for the period from July 1, 2000 through
          June 30, 2001.

          In any month, if the Hourly Usage Charge is not equal to or greater
than the applicable Minimum Monthly Usage Charge, you agree to pay us the
applicable Minimum Monthly Usage Charge as set forth above.

          For example (assumption: average monthly connect hours per Subscriber
is not in excess of 30 hours and no other amounts were due)

                       Minimum Monthly Usage Charge:
                              The Minimum Monthly Usage Charge you will be
                              required to pay for Subscriber connect services is
                              set forth in the paragraph above. July 1997: =
                              $3,000,000.


For purposes of determining connect hours, the sequence of a call is as follows:
The dial port
<PAGE>
 
         [Confidential Materials omitted and filed separately with the
       Securities and Exchange Commission. Asterisks denote omissions.]

 
goes off hook, modem synchronization, protocol management, call routed, Prodigy
authentication, session live while user performing tasks, user initiates end of
session or the session otherwise ends, eventually resulting in modem off-line
and session termination (carrier dropped). We will aggregate the total time of
all calls, rounded up by city to the nearest hour. The length of each individual
call will be calculated from the time the port goes off hook to session end
(modem off-line), rounded up to the nearest second.

6.5.2  Other Monthly Charges

       In addition to the charges provided in Section 6.5.1 above, you agree to
pay us each month for the following, which is dedicated for your exclusive use
and provided you approve of such use in writing:

       1.   for each NAP connection at a rate of [**] per month for each
            DS3 connection, at our choice of location, as are necessary for
            supporting your Subscribers,

       2.   for all remote and proxy server connections at a rate of [**]
            per month for each EtherNet connection at each remote and proxy
            server location,

       3.   for servers which you require in addition to those installed as of
            the date hereof, an amount for the acquisition, installation,
            operation and maintenance of hardware and software for such server,
            at our total cost plus 10% (including applicable sales tax).

       4.   If you ask us or no later than August 31,1997 to assume or provide
            any network related service obligations, not specifically disclosed
            in this Agreement, including its Exhibit and Schedules
            ("Supplemental Obligations"), we will assume such Supplemental
            Obligations in consideration for payment to us of our total cost
            plus 10% (including applicable sale tax); provided that, such cost
            plus 10% pricing shall not be applicable to any increase or
            variations in Supplemental Obligations, and the parties shall
            mutually agree on pricing for any such increase or variation.

6.5.3  Payment Terms

       Except as provided in the Transition Services Agreement while it is in
effect, you agree to pay us the applicable Minimum Monthly Usage Charge (plus
any other fixed charges) by the end of the calendar month that we provide the
Service, whether or not you receive an invoice for such charges, and to make
payments to us by wire funds transfer or other mutually agreed to electronic
means to an account specified by us. For all other charges, we shall make
reasonable efforts to provide invoices on or before the tenth day of the month
following the monthly period being invoiced and you agree to pay such invoices
within 30 days of the invoice date. If you do not make payments to us by their
applicable due dates, you agree to pay us a service charge equal to the lesser
of 1.5% per month or the maximum allowable rate under applicable law on each
unpaid amount. You agree to pay charges for all Service usage you or Subscribers
incur by any means, including providing a User Identification to access a
Service. You are responsible for charges and damages resulting from misuse of
User Identifications.

       Applicable taxes, such as sales, use or excise taxes are not included in
the above charges, and you will be invoiced for taxes payable by you but
required by law to be collected by us, but taxes shall not include line access
or similar telecommunications based charges.
<PAGE>
 
     We shall be responsible for payment of sales, use, property and other taxes
on machines, software, or goods and services used or furnished by us for our own
use in providing the Services to you. All taxes incurred in connection with our
upgrading of the network to ATM switching, or any other upgrade, whether
mandatory or voluntary, shall be our sole responsibility.

     You shall be responsible for sales, use, property and other taxes on
machines, software, or goods and services provided by you.

     All pricing for dial access covers speeds up to 56K bps. All pricing of
higher speed Service is subject to negotiation and agreement between the
parties.

6.6  Forecasts

     At the beginning of each quarter, you shall supply us with a rolling 15-
month forecast consistent with your business model:

     1.   hours of traffic for each site for each month of the forecast,

     2.   time of peak busy hour for each site,

     3.   average peak busy hour percentage for each site for each month of the
          forecast,

     4.   distribution of traffic by hour of day across all sites, and

     5.   average session length across all sites.

     We shall use this information to perform capacity planning for the Services
provided under this Agreement.

     For purposes of determining if a forecast is valid or invalid, the fourth,
fifth and sixth month of a forecast shall be recorded and saved and then
compared against the actual. The forecast for the specified month compared
against the actual is valid if the actual peak hours are no more than 15%
greater than the forecasted peak hours. If the actual peak hours are more than
15% greater than the forecasted peak hours, then the forecast for the month is
invalid and the SDGS objective does not apply for that month. For any month in
which a forecast is invalid, we shall not be responsible for SDGS or TD
objectives for the subject forecast period.

6.7  Changes and Default

     6.7.1  Undesirable Conditions.

            If any of the following undesirable events occurs for two
consecutive months or four months out of a twelve-month period, you may
terminate this Agreement upon 45 days written notice to us ("Notice of
Termination"):

            SDGS below P.05 for 30% or more of the sites
            SSA below 95% for 30% or more of the sites
            OSA below 95%
            TD above 250 millisecond monthly average, and 500 milliseconds
            monthly average for
<PAGE>
 
          Alaska and Hawaii.

          For SDGS and SSA undesirable condition calculations, a site is deemed
to be meeting its service level objective during any period of time when the
corresponding service level objective is not applicable. For OSA and TD, an
undesirable condition shall not apply during any period of time when the
corresponding service level objective is not applicable.

          If you desire to terminate this Agreement because of any of the
foregoing undesirable conditions, you must give us a Notice of Termination
within 30 days of receiving the monthly report that gives rise to your right of
termination. If you do not exercise your right of termination within such 30 day
period and in the next month the applicable undesirable condition no longer
exists, then you waive any right of termination for the applicable time period
and this Agreement shall remain in full force and effect.

          Upon Notification of Termination, we shall provide reasonable
transition assistance to you, for a period of up to six months, and no
termination adjustment charge or service level credits shall apply, nor shall
any Minimum Monthly Usage Charges apply after the effective date of termination.

6.7.2 System Wide Failure.

      If 50% of the point of presence sites are failing to provide access or
      Services for forty eight consecutive hours, then you have the right to
      enter our premises to operate our network assets and direct our employees,
      as is necessary to cure such failure, and we shall reimburse you for any
      reasonable expense you incur in doing so. We will cooperate with your
      efforts in restoring service to the network. You shall also have the right
      to terminate in accordance with the termination provisions within Section
      6.7.1.

6.7.3 Financial Related Defaults.

The occurrence of any of the following events shall constitute an Event of
Default (herein so called) hereunder:

1.    If we shall fail to perform any of our obligations and covenants under
Section 1.14; or

2.    If you, in good faith, after reviewing any document or report required to
be delivered under Section 1.14, believe that there has been a material and
adverse change in our business operations and conditions, financial or
otherwise, which in your reasonable opinion will have a materially adverse
effect upon the operations, business, property, assets, financial condition or
credit of us or you.

Remedies
- --------

Upon the occurrence of an Event of Default in this Section 6.7.3, you shall have
the right, at your option, to initiate an alternative dispute resolution by the
procedures set forth in Section 6.12. If the dispute is not resolved by
mediation, the arbitrators will be instructed to determine whether or not we, in
their judgment, are capable of performing our obligations under this Agreement.
A decision shall be rendered within three days of the conclusion of mediation or
arbitration, as appropriate.

We will respond within three business days to any reasonable request for
information made by the arbitrators.
<PAGE>
 

 
If the arbitrators' judgment is that we are not capable of performing our
obligations under this Agreement for the twelve month period after the
arbitrators render their decision, then you shall have the right, in your sole
discretion, to elect either (i) to terminate this Agreement, without penalty,
and be relieved of the Minimum Monthly Usage Charges, or (ii) to enter our
premises to operate our network assets and direct our employees to the extent
necessary to operate the network until the end of the Initial Term of this
Agreement, and we shall reimburse you for any reasonable expenses you incur in
doing so.

     6.7.4  Default (other than for Sections 6.7.1, 6.7.2 or 6.7.3)

            This Section 6.7.4 applies to defaults, other than for the events
described in Sections 6.7.1, 6.7.2 or 6.7.3.

            In the event that either party materially defaults in the
performance of any of its duties or obligations under this Agreement (other than
your failure to make timely payments due to us) and does not substantially cure
such default within 60 days after being given written notice specifying the
default, then the party not in default may, by giving written notice to the
defaulting party, terminate this Agreement (herein termination "for cause").

            In the event you do not make any payment of the Minimum Monthly
Usage Charge or Hourly Usage Charge due to us on the due date, then we may
terminate this Agreement 45 days after we give you written notice of such
default and provided that we did not receive good funds for such overdue payment
within the 45 day time period. In the event that you do not make any other
payment due to us within 30 days of your receipt of an invoice, and such failure
is not remedied within 60 days after we give you written notice of nonpayment
(the "Cure Period") then we may terminate this Agreement upon the expiration of
the Cure Period.

            In the event that you are in default (for reasons other than failure
to make timely payments due to us) and we elect to terminate this Agreement,
then you may request an extension of this Agreement of up to six months as a
transition period, provided that we, in our discretion, agree to provide such an
extension.

            In the event that you terminate this Agreement because we are in
material default for reasons other than as described in Section 6.7.1 then we
will provide reasonable transition assistance to you, for a period of up to six
months and no termination adjustment charges or service level credits shall
apply.

            You may terminate this Agreement during the Initial Term without
cause by providing 12 months' prior written notice to us. If you terminate this
Agreement without cause, or if we terminate this Agreement for cause, you shall
pay us a termination adjustment charge as follows: $7,000,000 if terminated in
the first year of the Agreement; $5,000,000 if terminated in the second year of
the Agreement; and $3,000,000 if terminated in the third year of the Agreement
Payment is due and payable upon the date termination notice is given and all
other terms and conditions of this Agreement shall remain in place.

6.8   Other Terms

      You will not be allowed to test or repair our dial network, except as
provided in Section 6.7.2., and except to send your own sample pings similar to
that described in section 6.2.3.
<PAGE>
 
6.9  Auditing Procedures

     We shall maintain true and accurate accounting records, in accordance with
sound accounting practices, to support the dial connect charges payable to us by
you. We shall, upon 30 days' prior written request, during normal business
hours, but not more frequently than once each calendar quarter, provide access
to the connect hour accounting records associated only with the provision of the
Service for the immediately preceding one-year period to an independent
accounting firm chosen and compensated by you for the purposes of auditing the
accuracy of the calculation of the dial connect charges. The accounting firm
selected shall: be required to sign an agreement with us protecting our
confidential information, perform such audit on our premises, and such other
locations reasonably necessary to conduct a proper audit, comply with our
security procedures, and be authorized by us to report only the results of such
audit and provide us with a copy of the report.

     In the event that the audit shows you owe an amount to us, we will invoice
you for such amount within the next two monthly billing cycles.

     In the event that the audit shows a credit due to you, we will process such
credit including the cost of the audit (but such costs shall not exceed the
credit), excluding travel and per diem charges, plus interest at the prime rate
on the entire amount until paid in full within the next two monthly billing
cycles, provided that we do not disagree with the audit report. If we disagree
with the audit report, we may select an independent accounting firm, compensated
by us, to perform an audit on the same information provided to the firm selected
by you. We shall provide you a copy of the report commissioned by us. In the
event that the audit reports disagree on the credit due to you, the credit due
to you will be determined by averaging the results of the two audit reports.

6.10 Primary Provider

     We shall be your Primary Provider of Services. You shall be free to make
agreements with third parties for Services, provided you shall not seek or
accept any bids for Services to replace our Services in their totality or to any
substantial extent. In addition, you shall not seek to bundle our Services with
other features which will have the effect of diverting traffic away from our
network in an amount which causes our traffic from you not to follow generally
the overall amount of your dial up access service needs; measured quarterly.

     You shall negotiate with us in good faith for any new service which we have
the ability, capacity and interest to provide. You shall be free to offer new,
experimental and other access including without limitation, ADSL, cable access,
modified cable access including dial up, satellite access, roaming (e.g.
Aimquest). Web TV, access bundled with content of other applications, agreements
with regional bell operating companies or long distance companies as marketing

                             -------------                                    
entering into any agreement or arrangement for Other Business, you will deliver
to us on a confidential basis any business plan changes, projections, draft
agreements and other documents describing such Other Business and meet with us
to discuss such Other Business.

     You shall not offer Other Business that would result in a material increase

6.11  Additional Services and Products

      You may request us to provide you services, products or enhancements which
are not the subject of this Agreement, which include services, products or
enhancements which we provide to other customers. If we provide such services,
products or enhancements, we agree that we will offer you a price for such
services or products which is no higher than the price we charge any other party
for the same services, products or enhancements; provided, however, that you
will not be entitled to receive this price treatment with respect to any
product, service or enhancement which we have developed for another party, or
which we consider to be proprietary.

your use and we agree to develop such product or service, then we will charge
you a price which will include a profit to us.

6.12  Alternative Dispute Resolution

      In the event of a dispute between you and us arising out of or relating to
this Agreement, or the breach thereof, you and we shall submit the dispute to
nonbinding mediation and shall make a good-faith effort to resolve the dispute
through the mediation process. In the event the dispute is not resolved through
mediation within 30 days following written notice by one party that it desires
to enter into mediation, then such dispute shall be resolved exclusively and
finally by binding arbitration by three arbitrators who will be appointed and
will act as follows:

      The party requesting arbitration shall, simultaneously with such request,
appoint one arbitrator and shall notify the other of such appointment together
with such arbitrator's acceptance. Within 30 days from the receipt of such
notice, the other party shall appoint another arbitrator and shall notify the
requesting party of such appointment together with the second arbitrator's
acceptance. The third arbitrator, who shall act as chairman of the arbitration
panel, shall be appointed by the other two arbitrators within the following 30
days. In the event either party fails to appoint an arbitrator or in the event
no agreement is reached between the two arbitrators as to the appointment of the
chairman of the arbitration panel in accordance with the foregoing provisions,
such arbitrator or arbitrators shall be appointed, upon application by the
interested party, by the American Arbitration Association (AAA).

     The arbitrators shall apply the arbitration rules of the AAA.

     The award of the arbitrators shall be final and shall not be subject to any
appeal or challenge whatsoever. The arbitrators will not be required to file
their award with any body or authority whatsoever. In the event arbitration
proceedings are initiated under this section, pending such proceedings and until
a final award is rendered pursuant thereto, any subsequent controversy arising
between the parties shall be exclusively submitted for final decision by the
arbitrators in the arbitration
<PAGE>
 
proceedings already pending. The arbitrators shall be instructed by the parties
to include an award for reasonable attorneys' fees, arbitrators' fees, expert
witnesses, travel and other costs incurred.

     If a dispute arises out of an alleged breach of this Agreement (other than
your failure to make timely payments due to us), then you and we agree to
continue to perform our respective obligations under this Agreement until an
agreement is reached through mediation or the arbitrators render a decision,
whichever is applicable.

Agreement.

     2.  Fixed Rent. (a) The obligation of Sublessee to pay fixed annual rent
         ----------

shall be paid to Sublessor at the time the assets are delivered pursuant to the
Definitive Agreement between the parties.

          (c) All costs, charges and expenses which Sublessee assumes or agrees
to pay to Sublessor, pursuant to this Sublease, shall be deemed additional rent
and, in the event of nonpayment, Sublessor shall have the rights and remedies
herein provided for in the case of nonpayment of rent.

     3.   Additional Rent. Sublessee shall also pay to Sublessor as additional
          ---------------

any calendar year after 1997 and (ii) the following services which shall be made
available by Sublessor to Sublessee: the use of common areas of the Building;

          ---
any use permitted by the Prime Lease, and for no other purpose. The Subleased
Premises are only a portion of the Building, and therefore, the parties

and unless security measures are installed and enforced, the employees, agents,
invitees, and licensees of each party ("Persons") may have access to each
other's premises within the Building. Notwithstanding installation of
appropriate security measures, such Persons shall have access to the common
areas. Sublessee and Sublessor will cause each of their employees having access

     7.   Prime Lease. (a) Sublessee acknowledges that it has read and examined
          -----------                                                          
the Prime Lease, and the modification and amendment thereof, and is fully
familiar with all the terms, covenants and conditions on the Sublessor's part to
be performed thereunder, and that, subject to the express provisions of this
Sublease, all of the terms, covenants and conditions of the Prime Lease are
incorporated hereinthis Sublease, all of the terms, covenants and conditions of
the Prime Lease

                                       2
<PAGE>
 
are incorporated herein as if set forth at length, and those applying to the
Tenant therein shall apply to Sublessee.

          (b) Sublessee does hereby assume and agree to be bound by and perform
all of the terms, covenants and conditions on Sublessor's part to be performed
thereunder as the same affect the Subleased Premises. In the event Sublessee
shall default in the full performance of any of the terms, covenants and
conditions on its part to be performed under this Sublease, then Sublessor shall
have the same rights and remedies with respect to such default as are given to
Landlord under the Prime Lease with respect to defaults by Sublessor, as tenant,
under the Prime Lease. Notwithstanding the foregoing, this Sublease is separate
from and subordinate to the Prime Lease.

     8.   Alterations. Sublessee shall not make or permit the making of any
          -----------                                                      
alterations, decorations, installments, additions or improvements, in or to the
Subleased Premises without Sublessor's prior written consent, which shall not be
unreasonably withheld or delayed, and, additionally, any necessary prior written
consent of Landlord in accordance with the Prime Lease. Any work by Sublessee
shall comply with the governing provisions of the Prime Lease. Sublessee agrees
to pay all costs and expenses in connection with obtaining any consent required
by Landlord and in making such alterations, decorations, installments, additions
or improvements.

     9.   Assignment/Subleasing/Mortgages. (a) Sublessee may assign to an
          -------------------------------                                
affiliate of Sublessee this Sublease or further sublease the Subleased Premises
to an affiliate of Sublessee in whole or in part without the prior written
consent of Sublessor; provided however, that any such assignment shall not
release Sublessee from its obligations hereunder. Except as set forth in this
Paragraph 9(a), Sublessee may not mortgage, pledge or otherwise encumber,
whether voluntarily, by operation of law, or otherwise, this Sublease or further
sublease the Subleased Premises in whole or in part without the prior written
consent of Sublessor, which may be withheld by Sublessor in its sole discretion.

          (b) If the Subleased Premises or any part thereof be sublet or
occupied by any person or persons other than Sublessee, whether or not in
violation of the provisions of this Sublease, Sublessor may, after default by
Sublessee, collect rent from the subtenant or occupant and apply the net amount
collected to the curing of any default hereunder in any order or priority
Sublessor may elect, any unexpended balance to be applied by Sublessor against
any rental or other obligations subsequently becoming due, but no such
subletting, occupancy or collection of rent shall be deemed a waiver of the
covenants in this Article, nor shall it be deemed acceptance of the subtenant or
occupant as a tenant or a release of Sublessee from the full performance by
Sublessee of all of the terms, conditions and covenants of this Sublease.

          (c) Each and every assignee or transferee, whether as assignee or as
successor in interest of Sublessee or as assignee or successor in interest of
any assignees, shall immediately be and remain liable jointly and severally,
with Sublessee and with each other for the payment of the rent, additional rent
and other charges payable under this Sublease and for the due performance of all
covenants, agreements, terms and provisions of this Sublease on the part of
Sublessee to be paid

                                       3
<PAGE>
 
and performed to the full end of the term of this Sublease.

          (d) Any consent by Sublessor or the landlord under the Prime Lease
that may hereafter be given to any act of assignment, mortgage, pledge,
encumbrance or subletting shall be held to apply only to the specific
transaction thereby approved. Such consent shall not be construed as a waiver of
the duty of Sublessee or its successors or assigns to obtain from Sublessor and
the landlord under the Prime Lease consents to any other subsequent assignment,
mortgage, pledge, encumbrance or subletting, or as a modification or limitation
or the rights of Sublessor with respect to the foregoing covenants by Sublessee.

     10.  Services. (a) Sublessee shall be entitled to receive all services to
          --------                                                            
be rendered to the Sublessor under the Prime Lease for the Subleased Premises.

          (b) Subject to the provisions of Paragraph 11 hereof, Sublessee shall
also be entitled to receive all services which Sublessor secures for the
Subleased Premises. Sublessor shall continue to provide services to Sublessee as
such are existing on the date of this Sublease for the term of this Sublease, at
the same level as they exist on the date hereof. If Sublessor seeks to modify in
any material respect the services delivered to the Subleased Premises, Sublessor
shall consult in good faith with Sublessee in determining the scope, if any, of
such modification. Upon conclusion of any such agreement to modify such
services, Sublessee shall pay its pro-rata cost of any additional cost incurred
as a result of such modification, and will receive the benefit of any reduction
in cost as a result of such modification. If Sublessee does not agree to the
modification of services, then Sublessee shall not be required to pay any cost
of such modification.

     11.  Electrical Service. (a) Sublessee agrees not to connect any
          ------------------                                         
electrical equipment of any type to the Building electric distribution systems
not permitted under the Prime Lease or which would adversely affect the
electrical system without the prior written consent of Sublessor and Sublessor's
landlord under the Prime Lease.

          (b) Sublessee agrees that in the event Sublessor is required to
provide electric service through an emergency power system Sublessor may
terminate the ancillary services to be provided by Sublessor under Paragraph 3.B
hereof during such period the emergency power system is used.

     12.  Prime Landlord Default. If the landlord under the Prime Lease shall
          ----------------------                                             
default in the performance or observance of any of its agreements or obligations
under the Prime Lease (including any obligation for the payment of money),
Sublessor shall have no liability therefor to Sublessee and shall be excused
from performance of the corresponding obligation which may be owed to Sublessee
under this Sublease. In this connection, Sublessor shall fully cooperate with
Sublessee in the assertion of any claims hereunder, in the name of Sublessee or
otherwise, against Sublessor's landlord. No such default shall excuse Sublessee
from the performance of any of its obligations to be performed under this
Sublease, or entitle Sublessee to terminate this Sublease or to any reduction

                                       4
<PAGE>
 
in or abatement of any of the rents provided for in this Sublease, unless, and
only to the extent that, Sublessor shall be excused from the performance of a
corresponding obligation as the tenant under the Prime Lease, or shall be
entitled to a reduction in or abatement of any of the rents provided for in the
Prime Lease with respect to these Subleased Premises, by reason of such default
by the Sublessor's landlord.

     13.  Sublessee's Obligation to Cure Defaults. Anything contained in any
          ---------------------------------------
provision of this Sublease to the contrary notwithstanding, Sublessee agrees,
with respect to the Subleased Premises, to comply with and remedy any default in
this Sublease or the Prime Lease which is the Sublessee's obligation to cure,
within the period allowed to Sublessor as tenant under the Prime Lease even if
such time period is shorter than the period otherwise allowed therein due to the
fact that notice of default from Sublessor to Sublessee is given after the
corresponding notice of default from Sublessor's landlord to Sublessor.
Sublessor agrees to forward to Sublessee, promptly upon receipt thereof by
Sublessor, a copy of each notice of default received by Sublessor in its
capacity as tenant under the Prime Lease. Sublessee agrees to forward to
Sublessor, promptly upon receipt thereof, copies of any notices received by
Sublessee from the Sublessor's landlord or from any governmental authorities
affecting the Subleased Premises.

     14.  Indemnification. Sublessee does hereby indemnify Sublessor and
          ---------------                                               
agrees to defend and to hold Sublessor harmless of and from any claim,
liability, damage or loss whether under the Prime Lease or otherwise, by reason
of any negligent act or negligent omission on the part of Sublessee hereunder
including, without limitation, all cost and expense of Sublessor associated with
enforcing this indemnification.

     15.  Insurance. Sublessee shall obtain and maintain throughout the term
          ---------                                                         
hereof the insurance Sublessor is obligated to maintain as tenant under the
Prime Lease and Sublessee shall cause both the landlord under the Prime Lease
and Sublessor to be named as additional insureds on all such policies. Sublessee
shall deliver evidence of such insurance, in accordance with the terms of the
Prime Lease, to Sublessor on or before July 1, of each year of the term.

     16.  Security Deposit. Sublessee shall not be required to deposit any sums
          ----------------                                                     
as security for its performance under this Sublease.

     17.  Sublessee's Representations. Sublessee represents that it is a duly

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

terms or other conditions and neither party has relied upon any representation,
express or implied, not contained in this Sublease. All prior undertakings,

     19.  Sublessor's Obligations. Sublessor covenants that so long as Sublessee
          -----------------------                                               
is not in default under this Sublease, and subject to Sublessee's obligations
hereunder, Sublessor will not default in any of its material obligations under
the Prime Lease during the term hereof. If Sublessor shall default on any of its
material obligations under the Prime Lease, Sublessee may terminate this
Sublease with no further obligation hereunder. Sublessor further covenants that
subject to the provisions of the Amendment to Lease, if Sublessor seeks to
exercise its rights to early termination of the Prime Lease, pursuant to the
Amendment to Lease, it shall do so at its sole cost and expense and only with 
Sublessee's consent, which consent shall not be unreasonably withheld. Sublessor
will not voluntarily enter into any agreement with the landlord under the Prime
Lease which would result in the termination of the Prime Lease prior to the
expiration or sooner termination of this Sublease, without Sublessee's express
prior written consent, which consent shall not be unreasonably withheld.

AMENDED AND RESTATED LEASE, made the 19th day of September, 1997 between
WESTCHESTER ONE LLC, a New York limited liability company, having its principal
office at 700 White Plains Road, Scarsdale, New York 10583 (hereinafter referred
to as "Landlord"), and PRODIGY SERVICES CORPORATION, a Delaware corporation
having an address at 445 Hamilton Avenue, White Plains, NY 10601 (hereinafter
referred to as "Tenant").

WHEREAS Landlord and Tenant entered into a Lease dated August 14, 1997 relating
to space at the building known as Westchester ONE located at 44 South Broadway,
White Plains, NY; and

WHEREAS Landlord and Tenant desire to amend and restate such Lease as herein-
after set forth. 

          NOW, THEREFORE, Landlord and Tenant agree as follows:


                              ARTICLE 1 PREMISES

          Landlord hereby leases to Tenant, and Tenant hereby hires and takes
from Landlord (i) approximately 82,356 square feet of rentable space consisting
of the entire 8th and 9th floors, (herein referred to as the "Office Space") and
(ii) up to 7,000 square feet of rentable storage area on Lower Level 3 as
provided in Article 33 hereof (the "Storage Area"), together with the parking
spaces as provided in Article 28 (collectively the "Premises"), in the building
known as Westchester ONE, consisting of approximately 851,769 square feet of
rentable office area and parking structure (collectively the "Building"), which
is situated on real property (the land), located at 44 South Broadway, in the
City of White Plains, County of Westchester, State of New York 10601, a legal
description of which is attached hereto as Exhibit B, together with the right of
access to Tenant, its employees, agents, invitees and servants, in common with
all others lawfully entitled thereto, on, over and through the common areas of
said Building.

          Landlord represents and warrants as a further condition of this Lease
that it has good marketable fee title to the Building and the land (subject only
to the exceptions set forth on Exhibit E attached hereto) and has the right to
enter into this Lease upon the terms hereof; that the provisions of this Lease
do not conflict with or violate the terms of existing mortgages, security deeds,
deeds of trust, easements, licenses, permits, leases, contracts or other such
agreements, that the Premises and the common areas of the Building, including,
without limitation the parking structure, and the uses thereof for the purposes
specified in this Lease are in conformity with all applicable legal
requirements, including, without limitation, zoning and planning ordinances, and
do not violate applicable restrictions.


                                 ARTICLE 2 USE

          The Premises may be used and occupied by Tenant for general offices,
sales, display, storage and use of Tenant's products and equipment, engineering,
education and training, parking of cars, kitchen, and all other uses incidental
and related thereto. The Premises may not be used for purposes of a retail
store.

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

          If any governmental license or permit, other than a certificate of
occupancy, shall be required for the proper and lawful conduct of Tenant's
business in the Premises or any part thereof, Tenant, at its expense, shall duly
procure and thereafter maintain such license or permit and submit the same to
Landlord for inspection. Tenant shall at all times comply with the terms and
conditions of each such license or permit. Landlord shall cooperate with Tenant
(at Tenant's expense) and shall join with Tenant, if necessary, in any
application with respect to obtaining or renewing any permit necessary in
connection with any use permitted herein.

          Tenant shall not at any time use or occupy the Premises in violation
of the certificate of occupancy at such time issued for the Premises or for the
Building (the "Certificate of Occupancy"), a copy of which is attached hereto as
Exhibit F, and in the event that any department of the City of White Plains, the
County of Westchester or the State of New York shall hereafter contend or
declare by notice, violation, order or in any other manner whatsoever that the
Premises are used for a purpose which is a violation of such certificate of
occupancy, Tenant shall, upon written notice from Landlord or any governmental
authority, immediately discontinue such use of the Premises, subject to Tenant's
right to contest such contention or declaration or right to require that
Landlord do so. Landlord represents and warrants that the uses specified in this
Article 2 will not violate the Certificate of Occupancy in effect on the date of
this Lease. Landlord covenants not to do (or give its permission to do) any act
which would cause the Certificate of Occupancy to be amended in such a way that
the uses specified in this Article 2 would, as a result thereof, be in violation
of such amended Certificate of Occupancy.

          So long as Prodigy Services Corporation is the Tenant under this Lease
and actually occupies at least fifty percent (50%) of the Office Space of the
Premises, Landlord shall not lease other space in the Building to those
entities listed in Exhibit G.


                                ARTICLE 3 TERM

          Initial Term: The initial term of this Lease shall commence upon
execution of this Lease (the "Commencement Date") and shall expire on December
31, 2004, or on such earlier date upon which the term of this Lease shall expire
or be canceled or terminated pursuant to any of the conditions or covenants of
this Lease or pursuant to law (the "Initial Term").

          Extension: Provided Tenant is not then in default under the terms of
this Lease beyond any applicable notice and grace period, and further provided
that this Lease has not heretofore been terminated pursuant to the provisions
hereof, Tenant shall have the option to renew this Lease for two additional
terms of five years each (the "Renewal Terms"), commencing upon the expiration
of the Initial Term, and the first Renewal Term, respectively. The options to
renew shall be of no force and effect unless exercised by Tenant giving written

================================================================================

notice to Landlord not later than eighteen (18) months prior to the expiration
of the Initial Term and the first Renewal Term, respectively.

     The Base Rent payable during a Renewal Term shall be at 100% of the fair
market rental value of the Premises determined as of the date of agreement
between Landlord and Tenant or the decision of the arbitrators as provided
below. The Base Rent shall be determined by agreement in writing between Tenant
and Landlord within forty-five (45) days after the giving of Tenant's notice of
exercise of its right to a Renewal Term. In the event Tenant and Landlord fail
to agree within such 45-day period, the Base Rent shall be determined by
arbitration, in accordance with the procedures set forth below, on the basis of
the then fair market rental value of the Premises. In determining fair market
rental value the arbitrators shall take into consideration the following items:
(A) all costs payable by Landlord in respect of the Renewal Term to Tenant
whether in the form of commission or rent abatement; (B) all costs Landlord will
avoid paying that would be incurred by Landlord (similar to costs incurred by
other landlords of similar buildings in the White Plains Central Business
District at the time of such determination) in the event that Landlord leased
the Premises to a third party, including, without limitation, (i) rent
concessions granted to a third party tenant, and (ii) costs to alter space for
third party tenants; and (C) the length of the Renewal Term. The base tax year
(i) during the first Renewal Term shall be the calendar year 2005 and (ii)
during the second Renewal Term shall be the calendar year 2010. The base year
with respect to operating expenses (i) during the first Renewal Term shall be
the calendar year 2005 and (ii) during the second Renewal Term shall be the
calendar year 2010. Pending determination of the Base Rent for a Renewal Term,
Tenant shall pay on a monthly basis the Base Rent and additional rent payable by
Tenant immediately prior to the commencement of the Renewal Term in question.
The sums paid as Base Rent by Tenant during the Renewal Term prior to
determination of the renewal rent as provided in this Article shall be subject
to adjustment at such time as the renewal rent is determined pursuant to this
Article and any amount owed to Tenant shall be applied to the next installments
of Base Rent or additional rent hereunder and any amount owed to Landlord shall
be paid by Tenant to Landlord within fifteen (15) days after such determination.

     In the event of arbitration as set forth above, each party shall select a
real estate appraiser in Westchester County to act as arbitrator and shall
notify the other party of its selection within ten (10) days next following the
expiration of the 45-day period described above. If either party shall fail to
make a selection within the 10-day period, the other party shall have the right
to select an appraiser of its choice to act as the second arbitrator. Following
the selection of the first two arbitrators, the two arbitrators so chosen shall
have an additional period of fifteen (15) days to reach an agreement as to the
matter in question. In the event the two arbitrators fail to agree within such
15-day period, they shall select a third arbitrator. The selection of the third
arbitrator shall be made and notice given to the parties within ten (10) days of
the expiration of the 15-day period described in the preceding sentence. If the
two arbitrators fail to agree on the selection of a third arbitrator, the
arbitrator shall be selected by The American Arbitration Association or its
successor organization (the "AAA") and application to the AAA shall be made
immediately. Each arbitrator selected or designated under this paragraph

shall be unaffiliated with either Landlord or Tenant, and shall be a person who
is a member of the American Society of Real Estate Appraisers (or successor
thereto) with at least fifteen (15) years experience in the valuation of fair
market rentals in office buildings in Westchester County. Following the
selection of the panel, the panel shall fix a date, time and place in the City
of White Plains and the State of New York, for a hearing to determine the matter
in question. The hearing shall commence within fifteen (15) days of the
selection of the panel, and the panel shall give notice to each party of the
hearing within five (5) days of the selection of the panel.

          The conduct of the arbitration hearing shall be governed by the
following provisions:

     (i)  The decision of a majority of the arbitration panel shall be binding
          on the parties;

    (ii)  The introduction of evidence at the hearing shall be governed by
          informal rules of evidence, subject to the discretion of the panel of
          arbitrators, and the arbitrators shall have the right to thoroughly
          inspect the Building and the Premises and to obtain and require the
          introduction into evidence of any other information normally required
          for the appraisal of comparable leasehold interests;

   (iii)  Neither party shall have the right to appeal from the decision of the
          panel, except on a showing of fraud, misrepresentation or lack of due
          process;

    (iv)  The expenses and fees for each of the first two arbitrators shall be
          paid by the party required to choose the a arbitrator. The fees and
          expenses of the third arbitrator shall be divided equally between the
          parties;

     (v)  The panel shall determine the then fair market rental value of the
          Premises. The panel's determination shall be limited to a
          determination of the Base Rent, and the panel shall not have the right
          to change or alter the payment or amount of additional rent required
          to be paid by the Tenant pursuant to this Lease.

    (vi)  The panel shall conduct and conclude the hearing within a period of
          thirty (30) days, and shall render its decision within fifteen (15)
          days of the last day of the hearing.

    If this Lease shall be renewed in accordance with the provisions hereof, it
shall be so renewed upon all the covenants, agreements, terms, provisions and
conditions set forth in this Lease (and all of Landlord's representations and
warranties shall be true and correct on the commencement date of each Renewal
Term as if made thereon), except that following the

expiration of the first Renewal Term there shall be only one further renewal
period and following the expiration of the second Renewal Term, there shall be
no further renewal periods. In addition, the phrases "the term of this Lease",

construed to include, when the context so requires, the Renewal Terms.

                 Unless otherwise expressed, the word term, when used herein,
shall be deemed to include the Renewal Terms.

                 During the Initial Term, Tenant shall pay to Landlord an annual

         One Hundred Thirty Three Dollars ($1,997,133.00) a year, to be paid in
         advance in monthly installments of One Hundred Sixty Six Thousand Four
         Hundred Twenty Seven Dollars and Seventy Five Cents ($166,427.75) for

                 Two Million One Hundred Sixty One Thousand Eight Hundred Forty
         Five Dollars ($2,161,845.00) a year, to be paid in advance in monthly
         installments of One Hundred Eighty Thousand One Hundred Fifty Three
         Dollars and Seventy Five Cents ($180,153.75), for the period from

                 Two Million Three Hundred Twenty Six Thousand Five Hundred
         Fifty Seven Dollars ($2,326,557.00) a year, to be paid in advance in
         monthly installments of Two Hundred Seventeen Thousand Four Hundred
         Fourteen Dollars and Sixty Cents ($193,879.75), for the period from

                 Storage Area: Annual rent equal to the number of rentable
                 ------------ 
         square feet in the Storage Area multiplied by Twelve Dollars ($12) per

                 All Base Rent and additional rent shall be paid by Tenant to
Landlord without set off, deduction or abatement of any kind except as
specifically provided in this Lease.

                 Tenant shall be entitled to abatements of the entire monthly
Base Rent for the Premises during the period from the Commencement Date through
December 31, 1997 (the "Abatement Period"), provided that Tenant shall not be in
default beyond any applicable notice and grace period under any term or
condition of this Lease at any time during such period; Tenant shall not be
entitled to an abatement of, or credit against, (i) any additional rent due

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

pursuant to the terms of this Lease, including any additional rent due pursuant
to Exhibits C and D of this Lease, and (ii) for electric energy pursuant to
Article 7(E) of this Lease. Tenant shall also pay for all janitorial services
provided to the portion of the Premises for which janitorial services are
necessary during an abatement period commencing on the date Tenant takes
occupancy of the Premises in accordance with Landlord's normal charges therefor
which are currently $1 per rentable square foot a year plus the cost of
expendable supplies and paper products for the Premises.

                 If Tenant shall be in default under any term or condition of
this Lease beyond any applicable notice and grace period, at any time during the
Abatement Period, the abatement of Base Rent during such Abatement Period, as
the case may be, shall be suspended as of the date of expiration of any
applicable notice and grace period for such default. If Tenant cures the default
which resulted in the suspension of the abatement of Base Rent during an
Abatement Period, then the abatement of Base Rent during such Abatement Period,
as the case may be, shall resume as of the date such default is cured and shall
continue until Tenant realizes the full amount of the abatement of Base Rent or
the rent credit, as the case may be, unless and until the provisions of this
paragraph would again apply.

                 Base Rent and additional rent for any period of less than one
month shall be apportioned based on the number of days in that month.

                 Building holidays shall include the following:

                                  on a non-recurring basis.

                 Landlord agrees to furnish heat, ventilation, and air
conditioning beyond the above-stated hours at a reasonable rate determined by
Landlord which rate shall be calculated by Landlord in the same manner for all
tenants in the Building and which will reflect Landlord's cost for fuel,
electric and labor, plus an additional fee of ten percent (10%), provided that
notice requesting such service is delivered to Landlord in writing before noon
on a business day when such service is required for that evening, and by noon of
the preceding business day when such service is required on a Saturday, Sunday
or Building holiday.

     Notwithstanding the foregoing, Landlord shall, at its own cost and expense,

M. To 6:00 P.M.

                 Landlord's rate of supplying such additional services shall be

and other tenants, if any, located in the same HVAC zone who have also requested
the benefit of such service at the same time as Tenant. Landlord shall bill
Tenant on or before the last day of the month following the month in which such
charges are incurred, and shall submit with its invoice a tabulation of the

Landlord shall provide supplemental cleaning service, porter service, light
maintenance and other similar services for Tenant, at competitive rates and at a
cost to be agreed upon by the parties. Landlord shall separately invoice Tenant
on a monthly basis for such additional services. Tenant shall also pay
Landlord's cost (at competitive rates) for all expendable cleaning supplies and
paper products used for the Premises.

                 e. Landlord shall furnish electric energy to Tenant, up to the
capacity currently allocated to the Premises, for Tenant's use of such lighting
and other electrical fixtures, appliances and equipment as Tenant may use in the
Premises and shall furnish the Building with sufficient electric energy to
operate a first class office building. In the event any additional electrical
service is necessary beyond the capacity currently allocated to the Premises,
Landlord shall provide the same at Tenant's reasonable expense. Tenant shall
reimburse Landlord for the actual cost to Landlord (without mark-up) of
electrical current consumed within the Premises. Landlord has installed separate
electric meters on the 8th and 9th floors to measure Tenant's actual KWH
consumption of electricity and any repair or replacement of such meters shall be
at Landlord's expense. Any additional electric meters required by Tenant shall
be installed by Landlord at Tenant's expense. In the event the meters installed
on a floor measure consumption of space in addition to the Premises, then
Landlord shall make a reasonable allocation of the measured electricity
allocable to the Premises. Landlord shall invoice Tenant on a monthly basis for
such electricity less amounts previously paid pursuant to the next sentence and
Tenant shall pay such invoice within thirty (30) days. Tenant shall pay to
Landlord each month in advance an amount equal to $.0625 per rentable square
foot of space in the Premises as an estimate of the actual cost of such electric
current with appropriate adjustment made following the determination of the
actual cost of such electric current for such month. In the event of any
scheduled disruption of electric service by Landlord, Landlord shall give Tenant
at least 24 hours notice of such scheduled disruption.

         In the event Tenant receives any benefit or concession from the State
of New York, the City of White Plains or any utility company for electric energy
by reason of its occupancy of the Premises, Landlord and Tenant shall cooperate
to assure that Tenant receives such benefit or concession.

                 f. Landlord shall furnish water to Tenant for bathrooms,
pantries, sprinkler systems and drinking fountains at no expense to Tenant.

                 g. Removal of ice, snow and other debris from the sidewalks,

elevators during tenancy, for Tenant's loading, unloading, delivery and pickup
activity, twenty-four (24) hours a day, seven (7) days a week, except that
Tenant shall pay Landlord's actual cost for any personnel needed to operate the
freight elevator outside of normal business hours (which shall be the times and
days specified in paragraph (C) of this Article 7).

                 i. Fire detection and fire protection and security for the
Premises and the Building area twenty-four (24) hours a day, seven (7) days a

                 All rekeying of locks to the entrances to the Premises on each
floor after the initial rekeying shall be performed by Landlord, at Tenant's
reasonable expense, consistent with the existing master key system.


                     ARTICLE 8 IMPROVEMENTS AND ALTERATIONS

                 a. Tenant may from time to time, at its expense, make such
alterations (herein called "Alterations") in and to the Premises, excluding
structural changes, as Tenant may reasonably consider necessary for the conduct
of its business in the Premises, provided and upon condition that: (a) the
outside appearance of the Building shall not be affected; (b) the Alterations
are non-structural; (c) the Alterations are to the interior of the Premises and
no part of the Building outside of the Premises shall be affected; (d) the
proper functioning of the mechanical, electrical, sanitary and other service
systems of the Building shall not be adversely affected and the usage of such
systems by Tenant shall not be increased beyond the capacity of such systems
allocated to the Premises; (e) before proceeding with any Alteration which will
cost more than $250,000 (exclusive of the costs of decorating work and items
constituting Tenant's Property), as estimated by a reputable contractor, Tenant
shall submit to Landlord for Landlord's approval plans and specifications for
the work to be done, and Tenant shall not proceed with such work until it
obtains Landlord's approval; (f) for any Alteration which requires Landlord's
approval hereunder, Tenant shall pay to Landlord upon demand the reasonable cost
and expense of Landlord in (i) reviewing said plans and specifications and (ii)
inspecting the Alterations to determine whether the same are being performed in
accordance with the approved plans and specifications and all laws and
requirements of public authorities, including, without limitation, the
reasonable fees of any architect or engineer employed by Landlord for such
purpose; (g) before proceeding with any Alteration which will cost more than
$250,000 (exclusive of the costs of decorating work and items constituting
Tenant's Property), as estimated by a reputable contractor designated by
Landlord, Tenant shall obtain and deliver to Landlord either (i) a performance
bond and a labor and materials payment bond (issued by a corporate surety
licensed to do business in New York), each in an amount equal to one hundred
twenty-five percent (125%) of such estimate cost and in form reasonably
satisfactory to Landlord, or (ii) such other security as shall be reasonably
satisfactory to Landlord, it being understood that no such bond or other
security shall be required in the event the cost of the Alteration is covered by
Landlord's Contribution (as described below) or Tenant's net worth at such time
is more than one hundred (100) times the cost of the Alteration; and (h) Tenant
shall fully and promptly comply with and observe the rules and regulations of
Landlord then in force with respect to construction at the Building. The
provisions of clauses (e), (f) and (g) above shall not apply to the performance
by Tenant of any decorative or cosmetic work such as painting, wallpapering or
carpeting. The Alterations shall not, in the reasonable opinion of Landlord,
weaken or impair (temporarily or permanently) the structure or materially lessen
the value of the Premises or the Building either during the performance of the
Alterations or upon its completion. Within ten (10) business days of receipt of
the plans and specifications, Landlord shall notify Tenant, in writing, of
either Landlord's approval thereof or the reasons why Landlord's approval will
not

be given. If Landlord does not, within such ten (10) day period, give its
approval or notify Tenant of the reasons why Landlord's approval will not be
given, then such approval shall be deemed to have been given. Performance of the
Alterations requiring approval of plans and specifications may commence upon
Tenant's receipt of Landlord's written approval of the plans and specifications
and the delivery by Tenant to Landlord of all then required permits and
certificates of insurance from Tenant and all parties performing the
Alterations.

         No approval of plans or specifications by Landlord, or consent by
Landlord allowing Tenant to perform Alterations, or any inspection of
Alterations made by or for Landlord shall in any way be deemed to be an
agreement by Landlord that the contemplated Alterations comply with any legal
requirements or requirements of the New York Board of Fire Underwriters, or the
requirements of any carrier of insurance maintained by Tenant or with the
certificate of occupancy for the Building nor shall it be deemed to relieve
Tenant from complying with any provision of this Lease. However, approval of
such plans or specifications by Landlord shall constitute Landlord's
acknowledgment that the Alterations shown on such plans and specifications will
not affect Landlord's obligations under this Lease provided the Alterations are
performed in accordance with the plans and specifications. Notice is hereby
given that neither Landlord nor Landlord's agents shall be liable for any labor
or materials furnished or to be furnished to Tenant upon credit.

                 b. Tenant, at its expense, shall obtain all necessary
governmental permits, licenses, approvals and certificates, including
underwriter certificates, for the commencement and prosecution of Alterations
and shall promptly deliver duplicates of these to Landlord and shall cause
Alterations to be performed in compliance therewith and with all applicable law
and requirements of public authorities and with all applicable requirements of
insurance ?????? Landlord shall cooperate with Tenant (at Tenant's expense) with
respect to Tenant's obtaining the necessary permits, licenses, approvals and
certificates. Upon completion of the Alterations, Tenant shall obtain any
necessary certificates of completion (including, but not limited to approvals by
the City of White Plains Department of Buildings) and shall promptly deliver
original copies of these to Landlord. Landlord agrees to cooperate with Tenant
to obtain such certificates. Alterations shall be diligently performed in a good
and workmanlike manner, in accordance with the plans and specifications approved
by Landlord, using new materials and equipment substantially equal in quality
and class to the then standards for the Building established by Landlord.
Alterations shall be performed in such manner as not to unreasonably interfere
with or delay and as not to impose any additional expense upon Landlord in the
construction, maintenance, repair, operation cleaning, security or management of
the Building or the Building's equipment; and if any such additional expense
shall be incurred by Landlord, including without limitation, the expense of
providing additional electricity or electrical hook-ups or freight elevator
service, as a result of Tenant's performance of any Alterations, Tenant shall
pay such additional expense upon demand. Landlord shall furnish to Tenant in
writing a reasonably detailed explanation for any such additional expense. Any
dispute between Landlord and Tenant regarding such additional expenses shall be
resolved by arbitration in accordance

with Article 20 of this Lease. Tenant shall not make unreasonably loud noise
during Business Hours on Business Days in or about the Premises in performing
the Alterations.

                 c. Tenant agrees that it will employ, or cause to be employed,
only unionized contractors and sub-contractors in connection with the
performance of the Alterations. All contractors and subcontractors must be
approved of, in advance, by Landlord and will be subject to the provisions of
this Lease and the Rules and Regulations of the Building. Landlord hereby agrees
not to unreasonably withhold its approval of such contractors. Tenant's failure
to comply with this requirement shall constitute a default under this Lease.
Tenant agrees that it will not at any time prior to or during the Term, either
directly or indirectly, employ or permit the employment of any contractor,
mechanic or laborer, or permit any materials in the Premises, if the use of such
contractor, mechanic or laborer or such materials would, in Landlord's
reasonable opinion, create any difficulty, strike or jurisdictional dispute with
other contractors, mechanics or laborers engaged by Tenant or Landlord or
others, or would in any way disturb the construction, maintenance, cleaning,
repair, management, security or operation of the Building or any part thereof.
In the event of any interference or conflict, Tenant, upon demand of Landlord,
shall cause all contractors, mechanics or laborers, or all materials causing
such interference, difficulty or conflict, to leave or be removed from the
Building immediately.

                 d. Throughout the performance of any Alterations, Tenant, at
its expense, shall carry, or shall cause its contractors to carry, workmen's
compensation insurance in statutory limits and general liability insurance, with
completed operation endorsement, for any occurrence in or about the Building,
under which Landlord and its agent shall be named as parties insured, in such
amounts as Landlord may reasonably require, and excess liability in an amount
not less than a $5,000,000 single limit per occurrence, with insurers reasonably
satisfactory to Landlord. Landlord's insurance requirements shall not be in
excess of those generally required in the City of White Plains by owners of
buildings similar to the Building in connection with alterations of a nature
similar to those to be performed by Tenant. Tenant shall furnish Landlord with
reasonably satisfactory evidence that such insurance is in effect at or before
the commencement of Alterations and, on request, at reasonable intervals there
after during the continuance of Alterations.

                 e. If any Alterations shall involve the removal of any
fixtures, equipment or other property in the Premises which are not Tenant's
Property, such fixtures, equipment or other property shall be promptly replaced
at Tenant's expense with new fixtures, equipment or other property of like
utility and at least comparable value unless Landlord shall otherwise expressly
consent.

                 f. Tenant, at its expense, and with diligence and dispatch,
shall procure the cancellation or discharge of all notices of violation arising
from or otherwise connected with Alterations, or any other work, labor, services
or materials done for or supplied to Tenant, or any person claiming through or
under Tenant, which shall be issued by the Department of Buildings of the City
of White Plains or any other public authority having or asserting

jurisdiction. However, nothing herein contained shall prevent Tenant from
contesting, in good faith and at its own expense, any notice of violation.

                 g. In no event shall Tenant cause or allow a lien for labor or
materials to be filed against the Premises or the Building. If Tenant shall
allow such lien to be filed, then, within twenty (20) days after notice to
Tenant of the filing of such lien, Tenant shall discharge the same either by
paying the amount claimed to be due or by deposit or bonding proceedings, and,
if Tenant fails to do so, then, in addition to any other right or remedy,
Landlord may, but shall not be obligated to, upon ten (10) days prior written
notice to Tenant, discharge the same either by paying the amount claimed to be
due or by deposit or bonding proceedings, and in any such event Landlord shall
be entitled, if it elects, to compel the prosecution of an action for the
foreclosure of such lien and to pay the amount of the judgment in favor of the
lienor with interest, costs and allowances. Any amount so paid by Landlord, and
all costs and expenses incurred by Landlord in connection therewith, shall
constitute Additional Rent and shall be paid on demand.

                 h. During the performance of Alterations, as long as the
freight elevator(s) is in operating condition, Tenant shall not use the
passenger elevators (and if the passenger elevators may be so used, Tenant shall
take all necessary measures to protect the same from damage, and shall repair
any damage, caused by any such use). Tenant may notify Landlord that it desires
to use the freight elevator after Business Hours on Business Days or on
non-Business Days; such notice must be given twenty four (24) hours in advance
in the case of such use after Business Hours on Business Days and by 9:00 a.m.
of the immediately preceding Business Day in the case of such use on non-
Business Days. Except in the case of an emergency; Landlord shall make all
reasonable efforts to make the freight elevator available to Tenant at the
requested times. If Landlord provides a person to operate the freight elevator
for Tenant's dedicated use of the freight elevator in accordance with the
applicable policy of the Building, then Tenant shall pay Landlord's normal
charges for use of the freight elevator after Business Hours on Business Days
and on non-Business Days.

                 i. Upon completion of Alterations, Tenant shall furnish to
Landlord a detailed set of "as-built" drawings for Alterations, all final lien
waivers from all general contractors and subcontractors and, in the case of any
Alteration affecting the HVAC, an air balancing report by Tenant's engineer
acceptable to Landlord together with all other documents reasonably requested by
Landlord.

                 j. All such trade and other fixtures heretofore or hereafter
made or installed by Tenant shall remain the property of Tenant and in case of
damage or destruction thereto by fire or other causes, Tenant shall have the
right to recover the value thereof as its own loss from any insurance company
with which it has insured the same, or to claim an award in the event of
condemnation, notwithstanding that any of such things might be considered a part
of the Premises. Tenant may remove all or any of such fixtures at any time
during the term provided Tenant repairs, at its expense, any damage caused by
such removal. In the event Tenant does

not remove such fixtures after the expiration or earlier termination of this
Lease, such fixtures shall be deemed to be abandoned and Landlord may do as it
desires with respect thereto, at Landlord's cost. However, at Landlord's
request, Tenant shall remove, at Tenant's expense, any stairways, vaults,
kitchen equipment (and related plumbing and ventilation), any equipment which
penetrates any floor or any other above Building standard fixtures (collectively
the "Equipment") which Equipment was installed by, or at the direction of,
Tenant or a subtenant and which Landlord notified Tenant, at the time of
Landlord's approval of plans and specifications, shall be removed by Tenant upon
the termination or expiration of this Lease. Tenant shall restore any
penetration of a floor created by or at the direction of Tenant or by a
subtenant. Tenant shall not be required to restore any other portion of the
Premises on which any such equipment was located and Tenant shall have no other
restoration obligation not expressly set forth above.

                 K. Landlord shall, at Tenant's expense, perform the demolition
work in the Premises necessary to prepare the Premises for Tenant to do the
Tenant Fit-Up of the Premises. Such expense to be paid by Tenant shall not
exceed One Hundred Eighty One Thousand One Hundred Eighty Three Dollars and
Twenty Cents ($181,183.20), plus the actual cost of trash disposal. If Tenant
becomes entitled to a Landlord's Contribution referred to below, such expense
shall be deducted therefrom, otherwise such expense shall be paid by Tenant to
Landlord.

         Tenant has agreed to retain Landlord to perform the initial Tenant Fit-
Up in accordance with a separate agreement which agreement shall reflect
competitive prices for the performance of the Initial Tenant Fit-Up.

         Landlord shall contribute up to Thirty Eight Dollars ($38.00) per
rentable square foot of the Office Space of the cost of the initial Tenant
Fit-Up of the Premises ("Landlord's Contribution"). The costs of the Tenant
Fit-Up for which Landlord's Contribution may be used shall include the
construction shown on the plans and specifications approved by Landlord and up
to Five Dollars ($5.00 of Landlord's Contribution may be used by Tenant for soft
costs. If the cost of the Tenant Fit-Ups exceeds Thirty Eight Dollars ($38.00)
per rentable square foot, Tenant shall pay such excess costs. At any time Tenant
requests reimbursement from Landlord, whether for expenses incurred in, without
limitation, preparing plans and specifications, obtaining necessary governmental
permits or approvals, or performing the actual Tenant Fit-Up, Tenant shall
present Landlord with a receipt of the amount Tenant disbursed in connection
with said request and with a signed statement stating that the amount requested,
plus all sums previously requested, does not exceed the amount of Landlord's
Contribution, and certifying that the cost to complete the Tenant Fit-Up does
not exceed the remaining amount of Landlord's Contribution. Tenant shall not
submit requests for reimbursements more often than twice per calendar month and
Landlord shall pay any proper request for reimbursement within ten (10) days
after receipt of such request. Tenant may incur costs and expenses greater than
Landlord's Contribution but all such costs and expenses shall be borne solely by
Tenant.

Premises in good order and condition, reasonable wear and tear, damage by fire,
other casualty and the elements and repairs which Landlord is required to make

case Tenant shall repair any damage caused by such removal (normal wear and tear
excepted). Any property of Tenant which remains in the Premises after the
expiration of the term of this Lease shall be deemed to have been abandoned by
Tenant and may be retained by Landlord as its property or may be disposed of in
such manner as Landlord may see fit. Tenant shall pay Landlord for the cost of
removing any such property, except as otherwise provided in Article 8 hereof.

                 Subject to Article 8 hereof, Tenant will repair all damage or
injury to the Premises or the fixtures, appurtenances and equipment therein, or
to the Building, caused by Tenant's installation or removal of furniture or
other personal property or resulting from the negligence or willful act of the
Tenant, its contractors, licensees, agents or visitors, or vandalism that has
been directed at Tenant; provided, however, that any damage caused by Landlord
or its contractors, employees or agents shall be restored by Landlord at its
expense.


                              ARTICLE 10 INSPECTION

                 Landlord shall, upon advance oral notice to Tenant, (except 
in an emergency), have the right upon prior reasonable notice (i) at all
reasonable times during business hours, to enter the Premises to inspect the
same, and (ii) at all times, to make repairs or replacements therein as required
by this Lease, or as may be necessary, provided, however, that Landlord shall
use all reasonable effort not to disturb Tenant's use and occupancy of the
Premises and Landlord shall not store equipment or materials on the Premises
except in connection with any on-going repairs.

                               ARTICLE 11 CASUALTY

                 If the Building is damaged by fire or any other cause, the
following provisions shall apply:

                 a. If (i) the damage is to such extent that the cost of
        restoration, as estimated by Landlord, will equal or exceed thirty
        percent (30%) of the replacement value of the office area of the
        Building (exclusive of foundations) in its condition just prior to the
        occurrence of the damage and Tenant's access or use of the Premises is
        materially affected, or (ii) fifty percent (50%) or more of the Premises
        is rendered untenantable and, in either case such damage is estimated by
        Landlord to take longer than 180 days to repair (such estimation to be
        in writing and given to Tenant by no later than fifteen (15) days after
        such damage), Landlord or Tenant may, not later than the sixtieth (60th)
        day following the later of (a) the date such estimation notice is given,
        and (b) the date of the damage, give the other a notice stating that it
        elects to terminate this Lease. If neither party timely elects to
        cancel, Landlord shall immediately commence to repair and restore the
        damage and perform such work in a good and workmanlike manner using
        materials of equal or better quality than those that existed immediately
        prior to such damage. If, at the end of 180 days after the date of such
        damage, Landlord determines that it will take longer than a further
        ninety (90) days to repair (which Landlord shall advise Tenant of, in
        writing, within five (5) days after the completion of the first 180
        day-period), or the damage is not actually repaired within two hundred
        seventy (270) days after such damage, Tenant may give Landlord a notice
        stating that it expects to terminate this Lease. If the restoration
        would not be completed at the time when there is at least fifteen months
        remaining in the then term (including any Renewal Term with respect to
        which Tenant has properly and validly exercised its option therefor),
        Landlord may give Tenant a notice to terminate this Lease, except that
        Tenant may nullify Landlord's notice to terminate by exercising, within
        thirty (30) days after Landlord's notice, the right to elect, if
        available, a Renewal Term under Article 2 hereof. If the restoration
        would not be completed at the time when there is at least two years
        remaining in the then term (including any Renewal Term with respect to
        which Tenant has properly and validly exercised its option therefor),
        Tenant may give Landlord a notice to terminate this Lease. If any such
        notice of termination shall be given: (i) this Lease shall terminate on
        the third day after the giving of said notice; (ii) Tenant shall
        surrender possession of the Premises within a reasonable time
        thereafter; and (iii) the Base Rent and additional rent shall be
        apportioned as of the date of such damage based on the portion of the
        Premises rendered untenantable and any rent paid for any period beyond
        said date shall be repaid to Tenant.

                 b. If the cost of restoration, as estimated by Landlord, shall
        amount to less than thirty percent (30%) of said replacement value of
        the office area of the Building or if less than fifty percent (50%) of
        the Premises is rendered untenantable, or if, regardless of the amount
        of damage, the damage can be repaired within one hundred eighty (180)
        days, or if despite the time or cost Landlord and Tenant do not elect to
        terminate this Lease, Landlord shall restore the Building and the
        Premises as provided in the second sentence of Subparagraph A above,
        provided, however, if such restoration is not completed within two
        --------  -------
        hundred seventy (270) days of the damage Tenant shall be entitled to
        terminate this Lease upon notice to Landlord and the terms set forth in
        the final sentence of Subparagraph A above shall apply

                 Landlord need not restore fixtures, improvements or other
property of Tenant including the Tenant Fit-Up (as defined in Article 8).

                 In any case in which the use of or access to the Premises is
affected by any damage to the Building, there shall be either an abatement or an
equitable reduction in rent, depending on the period for which and the extent to
which the Premises are not reasonably accessible or usable for the purposes for
which they are leased hereunder. The words "restoration" and "restore" as used
in this Article shall include repairs.


                            ARTICLE 12 FIRE INSURANCE

                 Landlord shall, from and after the date of the execution of
this Lease, maintain insurance (from insurance companies licensed to do business
in the State of New York with a rating which is typically required by an
institutional lender for properties similar to the Building and located in the
White Plains Central Business district) covering the Building and Premises on an
all-risk basis against loss or damage by boiler explosion, fire, and against
damage from sprinkler leakage, in amount sufficient to meet the co-insurance
requirements of the policies, but not less than the full insurable value of the
Building, exclusive of the architectural and engineering fees, excavation,
footings and foundations. The term "full insurable value" shall mean herein the
cost of replacement.

                 Tenant and Landlord hereby mutually waive their respective
rights of recovery against each other for any loss to the extent insured by
fire, extended coverage and other property insurance policies existing for the
benefit of the respective party. Each party shall obtain any special
endorsements, if required by its insurer, to evidence compliance with the
aforementioned waiver and shall bear the cost of any additional premium charges
resulting therefrom.

                 Tenant shall have the obligation to comply with the rules and
regulations of the Board of Fire Underwriters and with applicable legal
requirements only as the same pertain to

the specific manner in which the Tenant shall use and occupy the Premises; and
Landlord covenants to comply with the same in all other circumstances. Landlord
represents and warrants that as of the date hereof neither the Board of Fire
Underwriters nor its insurer has made any demand or recommendations in
connection with the Building with which Landlord has not complied in all
material respects.


                             ARTICLE 13 CONDEMNATION

                 a. If, at any time during the term, the whole of the Premises
shall be taken for any public or quasi-public use under any statute, or by right
of eminent domain, or if any part of the Premises shall be so taken and the
remaining part shall be insufficient for the conduct of Tenant's business as
contemplated by this Lease in substantially the same manner as immediately prior
to the taking, or any part of the Building shall be taken so that access to the
Premises is materially impaired, or if more than thirty percent (30%) of the
parking structure shall be taken, then, in such event, the term hereby granted
and all rights of Tenant, except as hereinafter reserved, shall immediately
cease and terminate as of the date of such taking, and the Base Rent and
additional rents shall be apportioned and paid to the time of such termination.
In case of any such taking, whether involving the whole or any part of the
Premises, the entire award shall be paid to Landlord, except for the value of
the improvements to the Premises installed at Tenant's own expense (regardless
of whether the improvements shall be or become the property of Landlord under
the terms of this Lease), plus the value of its fixtures and for moving and
relocation expenses. If allowed by law, Landlord and Tenant may each file
separate claims and the award, if a joint one, shall be apportioned between
Landlord and Tenant in the same proportion as the claim established by each in
said proceeding bears to the entire award for the land, the Building and the
property and interest of Tenant covered by Tenant's claim, subject nevertheless
to the claim or claims, if any, of the holder of any mortgage to which this
Lease shall be subject and subordinate, on Landlord's portion of the award; but
if the public or governmental authority exercising such right of eminent domain
or otherwise shall refuse to permit separate claims to be proved and established
by Landlord and Tenant and/or to distribute said award as above provided,
Landlord shall prosecute all claims for damages on behalf of Landlord and
Tenant, and, after deducting all reasonable legal and other expenses incurred
incident thereto, Landlord shall apportion the balance of said award in
accordance with this Article. In the event this Lease is not canceled as
provided above, Landlord shall restore the Building as promptly as practicable.

                 b. In the event that only a part of the Premises shall be so
taken and if the part not so taken shall be reasonably sufficient to enable
Tenant to continue the conduct of its business in substantially the same manner
as prior to the taking on and in the remaining Premises, this Lease shall remain
unaffected, except:

                    (1) Tenant shall be entitled to a pro rata reduction of Base
         Rent and additional rents payable hereunder, based on the proportion
         which the area

of the Premises prior to such taking, provided that consideration shall be given
to the respective values of the area so taken, and the area not so taken, and
any dispute with respect to the amount of the reduction shall be resolved by
arbitration in the manner provided in this Lease;

                 (2) The entire award for a partial taking shall be paid to
Landlord which, at its own expense, shall restore the affected part of the
Building to substantially the same condition and tenantability as existed prior
to the taking, including all of Tenant's alterations. Tenant shall have no claim
against Landlord for any part thereof, except such as shall relate to Tenant's
special installations and Tenant's improvements of the Premises installed at
Tenant's expense (regardless of whether such improvement shall be the Landlord's
property under the terms of this Lease), the value of its fixtures and moving or
relocation expenses to the extent that the same are not restored by Landlord as
provided in the preceding sentence. If such partial taking shall occur in the
last year of the term of this Lease (including any Renewal Term with respect to
which Tenant has properly and validly exercised its option therefor), either
party, irrespective of the area of the space remaining may elect to terminate
this Lease and the term hereby granted, provided such party shall, within thirty
(30) days after having received notice of such taking, give notice to that
effect, and upon the giving of such notice, this Lease and the term hereby
granted shall expire and come to an end (except that Tenant may nullify
Landlord's notice to terminate by exercising, within thirty (30) days after
Landlord's notice, the right to elect, if available, a Renewal Term under
Article 2 hereof) upon the earlier of (i) the actual date of vesting of ?? and
(ii) the expiration of thirty-five (35) days following the date of said notice
of taking. The Base Rent and additional rents shall be apportioned and paid to
such earlier date. If either party shall so elect to end this Lease and the term
hereby granted, the entire award for partial condemnation shall be paid to
Landlord, and Tenant shall have no claim against Landlord for any part thereof,
except such as shall relate to Tenant's special installations and Tenant's
improvements of the Premises installed at Tenant's expense (regardless of
whether such improvement shall be the Landlord's property under the terms of
this Lease), the value of its fixtures and moving or relocation expenses.

                 (3) In the event the part so taken is, in Landlord's reasonable
opinion, not disruptive to Tenant's continuance of its business (in the manner
and for the purpose previously conducted) in the remainder of the Premises, the
question shall be submitted to arbitration.

                                ARTICLE 14 TAXES

                 Landlord shall bear the cost of, and pay when due and
otherwise, before any of the same shall be in default or carry interest or
penalties for late payment, all real estate taxes, assessments and other
governmental charges which shall be levied or assessed or which become liens
upon the Premises, land or Building during the term. Landlord reserves the sole
right to contest or review any real estate tax levied by legal proceedings
against the taxing authorities in such manner as Landlord may deem suitable and
appropriate. In the event the taxes are reduced, Tenant shall receive its
proportionate share of such reduction or refund (after reasonable expenses of
obtaining such reduction or refund) by reason of any reduction in the assessed
valuation. The obligations contained in this provision shall survive the
expiration or earlier termination of this Lease.

                 In the event Tenant receives any benefit or concession from the
State of New York or the City of White Plains for real estate taxes by reason of
its occupancy of the Premises, Landlord and Tenant shall cooperate to assure
that Tenant receives such benefit or concession.


                               ARTICLE 15 DEFAULTS

                 a. If Tenant shall default in the payment of the rent reserved
herein and said default shall continue for ten (10) days after written notice of
non-payment from Landlord to Tenant, this Lease shall fully and completely
expire on the tenth day from the date said notice is given, as though the Lease
and ????? herein had ended on said date, it being ???????? understood and agreed
that the payment of rent shall be of the essence of this agreement. If Tenant
shall default in the performance of any other term or condition of this Lease
and such default shall continue for a period of thirty (30) days after written
notice thereof from Landlord specifying such default, and thereafter shall
continue beyond such period as may be reasonably necessary to correct such
default and the Tenant is not diligently occupied in correcting the same, or, if
the Premises shall be vacant or abandoned and Tenant shall cease paying rent,
then, and in any such event, Landlord may give ten (10) days' notice of
intention, to end the term of this Lease and then upon the expiration of said
ten (10) days the term of this Lease shall, unless Tenant has cured such
default, expire as fully and completely as if that day were the day herein
definitely fixed for the expiration of said term, and Tenant shall then quit the
Premises and surrender the same, but shall remain liable as hereinafter
provided.

                 b. If the notices provided in the above paragraph shall have
been given and the term hereof shall expire as aforesaid, then Landlord may, in
accordance with applicable law, re-enter the Premises and dispossess Tenant and
the legal representatives of Tenant, or other occupants of the Premises, by
summary proceedings or other actions permitted by law, and remove their effects
and hold the Premises as if this Lease had not been made; and Tenant

hereby waives the service of notice of intention to re-enter or to institute
legal proceedings to that end.

          c. In case of such re-entry, expiration and/or dispossess by summary
proceedings or other actions permitted by law, (i) the rent shall become due
thereupon and be paid up to the time of such re-entry, dispossess and/or
expiration, together with such reasonable expenses as Landlord may incur for
legal expenses, attorneys' fees, brokerage and/or putting the Premises in good
order for re-rental; (ii) Landlord may relet the Premises or any part or parts
thereof, either in its own name or otherwise, for a term or terms which may, at
its option, be shorter or longer than the period which would otherwise have
constituted the remainder of the term of this Lease to such extent as Landlord,
in Landlord's reasonable judgment, considers advisable and necessary to relet
the same; and (iii) Tenant, or its successors, shall also pay Landlord as
liquidated damages for the failure of Tenant to observe and perform its
covenants contained herein, any deficiency between the rent hereby reserved, and
the net amount, if any, of the rents collected on account of the lease or leases
of the Premises for each month of the period which would otherwise have
constituted the remainder of the term hereof provided, however, if such
expiration occurs at a time when Tenant still has a right to cancel this Lease
under Article 34 hereof, Tenant's liability shall be limited to the Base Rent
and additional rent which would have been paid by Tenant had Tenant exercised
such cancellation right. In computing such liquidated damages there shall be
added to said deficiency such reasonable expenses as Landlord may incur in
connection with reletting such as legal expenses, attorneys' fees, brokerage and
for keeping the Premises in good order for reletting. Any such liquidated
damages shall be paid in monthly installments on the rent day specified in this
Lease, and any suit brought to collect the amount of the deficiency for any
month shall not prejudice in any way the rights of Landlord to collect the
deficiency for any subsequent month by a similar proceeding. Landlord, at its
option, may make such alterations, repairs, replacements and decorations to the
Premises as Landlord, in its reasonable judgment, considers advisable and
necessary for the purpose of reletting the Premises, and the making of such
alterations and decoration shall not operate or be construed to release Tenant
from liability thereunder. in the event of a breach beyond any applicable notice
and grace periods or threatened breach by tenant of any of the covenants or
provisions hereof, Landlord shall have the right of injunction and the right to
invoke any remedy allowed at law or in equity as if re-entry, summary
proceedings and other remedies were not herein provided for. Mention in this
Lease of any particular remedy shall not preclude Landlord from any other remedy
in law or equity. Tenant hereby expressly waives any and all rights of
redemption granted by or under any present or future laws in the event of Tenant
being evicted or dispossessed, for any cause, or in the event of Landlord
obtaining possession of the Premises by reason of the violation by Tenant of any
of the covenants and conditions of this Lease or otherwise.

                               ARTICLE 16 HOLDOVER

          If Tenant remains in the Premises for more than thirty (30) days
beyond the expiration of the term of this Lease, or as it may have been
extended, such holding over in itself shall not constitute a renewal or
extension of this Lease, but in such event, a tenancy from month to month shall
arise at a monthly rent equal to the greater of (i) 150% of the Base Rent and
additional rent payable by Tenant during the last month of the term of this
Lease, and (ii) the fair market rental value of the Premises.

                                ARTICLE 17 NOTICE

          Any notice or demand by Tenant to Landlord shall be in writing and
shall be served personally or by registered or certified mail, or Federal
Express or other reputable overnight delivery service which provides evidence of
receipt addressed to Landlord at the above address, until otherwise directed in
writing by Landlord, and any notice or demand by Landlord to Tenant shall be
served personally or by registered or certified mail, or Federal Express or
other reputable overnight delivery service addressed to Tenant, if before
occupancy of the Premises, at 445 Hamilton Avenue, White Plains, NY 10601 Attn:
General Counsel, and, if after occupancy, at the Premises, or to such other
persons or at such other addresses as Tenant shall advise Landlord in writing.
Notices given by registered or certified mail or hand delivery shall be deemed
given when received or refused. Notices given by overnight mail shall be deemed
given on the next business day after such notice is sent. 

                       ARTICLE 18 ASSIGNMENT; SUBLETTING

          Tenant may assign this Lease in whole or in part or sublet all or any
part of the Premises at any time during the term hereof, without the consent of
Landlord but with notice to Landlord, to its parent or any of its subsidiaries,
divisions or affiliates, or to any partnership, corporation or other entity with
which it may become merged or affiliated, or to which its business may be
transferred, or which may be in replacement or succession of itself (the
"Permitted Transferees") except that an assignee must have a net worth computed
in accordance with generally accepted accounting principles at least equal to
the greater of the net worth of Tenant on the date of the assignment and the net
worth of Tenant on the date of this Lease and no such assignment or sublet shall
release Tenant from its obligations under this Lease. Otherwise, Tenant may
assign this Lease in whole or in part or sublet all or any part of the Premises
at any time during the term hereof, with the consent of Landlord, which consent
shall not be unreasonably withheld or delayed, subject to the right of the
Landlord to cancel this Lease in the event of an assignment or subletting other
than to a Permitted Transferee, subject to and as hereinafter provided. Except
where no consent is required, Tenant shall give Landlord twenty (20) days'
notice of its intent to assign or sublet and shall give the name of the tenant
who shall occupy the space and use proposed by said tenant. Landlord shall have
twenty (20) days after

receipt of said notification to notify Tenant, in writing, of its election to
permit the assignment or subletting or to cancel this Lease as it relates to the
space proposed to be sublet (in which case Base Rent and additional rent shall
be correspondingly reduced), or to cancel this Lease in the extent of a proposed
assignment. Failure of Landlord to give notice to Tenant of its election,
approval or disapproval, within said twenty (20) day period shall constitute
consent to Tenant's proposed assignment or sublet, as the case may be. If
Landlord permits Tenant, by written consent or by operation of this Article, to
make such assignment or subletting, Tenant shall remain responsible for the
faithful performance of all of the covenants, terms and conditions hereof on the
Tenant's part to be performed.

          If Tenant shall receive any consideration from an assignee for or in
connection with the assignment of this Lease (including, but not limited to,
sums paid for the sale or rental of Tenant's fixtures, leasehold improvements,
equipment, furniture, or other personal property, less, in the case of a sale
thereof, the then net unamortized or undepreciated cost thereof determined on
the basis of Tenant's federal income tax returns) Tenant shall account to
Landlord therefor and shall pay over to Landlord fifty percent (50%) of such
consideration as shall be paid to Tenant by the assignee after deduction of the
reasonable costs of brokerage commissions, attorneys, advertising, promotion and
marketing costs, the costs of fitting out the Premises for an assignee, fees and
other reasonable and customary costs incurred by Tenant in connection with such
assignment.

          If Tenant shall sublet the Premises, or any part thereof, to anyone
for a rent which for any period shall exceed the Base Rent and additional rent
payable under this Lease for the same period, Tenant shall pay Landlord, in
equal monthly installments as additional rent hereunder, fifty percent (50%) of
any rents, additional charges or other considerations paid under the sublease to
Tenant by the sublessee which is in excess of such rent accruing under this
Lease during the term of the sublease (hereinafter referred to an "Excess
Sublease Rent"). For purposes of determining the Excess Sublease Rent (i) there
shall be included any consideration from a sublessee for or in connection
with the sublease (including, but not limited to sums paid for the sale or
rental of Tenant's fixtures, leasehold improvements, equipment, furniture, or
other personal property, less, in the case of a sale thereof, the then net
unamortized or undepreciated cost thereof determined on the basis of Tenant's
federal income tax returns), and (ii) there shall be deducted from the excess of
the rent payable under the sublease over the Base Rent and additional rent
payable under this Lease, the reasonable costs of brokerage commissions,
attorneys' fees, advertising, promotion and marketing costs, costs of
subdividing the sublet space the costs of fitting out the sublet space for a
sublessee, and other reasonable and customary costs incurred by Tenant in
connection with such subletting, until such costs have been recovered by Tenant.
In computing Excess Sublease Rent, an appropriate proration of the Base Rent and
additional rent accruing under this Lease shall be made with respect to a
subletting of less than all of the Premises. If a demising wall needs to be
constructed between the subleased premises and the remainder of the Premises,
Landlord shall perform such construction at Tenant's expense.

          Tenant covenants and agrees that in any case where Tenant claims
Landlord is unreasonably withholding its consent, Tenant shall not make any
claim against Landlord for damages but shall be restricted to seeking equitable
relief in any arbitration proceeding, pursuant to the provisions of this Lease
except that Tenant may seek equitable relief from the Supreme Court of the State
of New York (or other court of competent jurisdiction) in the event equitable
relief would not be available in an arbitration proceeding or as needed on an
emergency basis.

          No subleasing permitted hereunder shall release or relieve Tenant from
its obligations fully to perform all of the terms, covenants and conditions of
this Lease on its part to be performed. The affiliates to whom Tenant subleases
all or a portion of the Premises may not sub-sublease or assign any of their
rights under such subleases except in compliance with this Article.

notice, and expiration of Tenant's time to cure such default, collect rent from

subtenant or occupant as tenant, or a release of Tenant from the performance by
Tenant of Tenant's obligations under this Lease. The consent by Landlord to
assignment, subletting or use or occupancy by others shall not in any way be

Letter of Credit within such one (1) week, then Landlord may elect to terminate
this Lease by written notice to Tenant. The Letter of Credit must be drawn upon
a bank acceptable to Landlord and upon terms acceptable to Landlord and shall be
for a term of not less than one (1) year. Not later than thirty (30) days prior

by Landlord due to such breach on the part of Tenant including, without
limitation, any cost or deficiency arising in connection with reletting the
Demised Premises or any portion thereof, and Tenant upon demand shall forthwith
restore the Letter of Credit, as applicable, to the original sum delivered. In
the event of the termination of this Lease by reason of the default of Tenant,
Landlord may draw down the entire amount of the Letter of Credit and retain such
amount as liquidated damages and the amount drawn down shall be credited against
the amount of damages payable by Tenant to Landlord by reason of such
termination. In the event of bankruptcy or other creditor-debtor proceedings
against Tenant, the Letter of Credit shall be deemed to be applied first to the
payment of Annual Base Rent and other charges due Landlord under the terms and
conditions contained in this Lease. Provided Tenant shall have made all payments
and performed all covenants and agreements of this Lease, the Letter of Credit
shall be returned to Tenant after the expiration of the Term.

ordinary wear and tear shall not be deemed defects; depreciation or other
non-cash items; any cost relating to a refinancing of any debt secured by the
Building; management fees; the cost of installing, operating and maintaining a
specialty improvement, including, without limitation, an observatory,

     Not later than April 30 following the end of calendar year 1999 and each
calendar year thereafter during the term of this Lease, Landlord shall cause its
operating expenses for the Building and land to be audited by an independent
certified public accounting firm and shall prepare a detailed statement of
comparative operating expenses, together with a computation of the additional
rent due, if any. Tenant shall be furnished a copy of such statement and
computation, and within thirty (30) days after its receipt, except as provided
below, shall pay Landlord the additional rent so calculated.

     Prior to determination of the actual amount of Tenant's share of the
increase in Operating Expenses for any year during the term of this Lease,
Tenant shall make monthly installment payments toward such share on an estimated
basis, based on Landlord's reasonable good faith estimate of Operating Expenses
for such year. Landlord may, at any time during such year, but not more than two
(2) times during such year, revise, in good faith, Landlord's estimate of
Operating Expenses for such year and provide Tenant in writing with the basis
therefor. Tenant shall pay Landlord, as additional rent commencing on the first
day of January, 1999 and on the first day of each month thereafter
simultaneously with payments of annual Base Rent for each month during the term
of this Lease, one-twelfth (1/12th) of Landlord's good faith estimate of
Tenant's share of Operating Expenses for such upcoming year.

     Landlord shall, at Tenant's request, make available to Tenant for its
inspection and examination, all the books and records that relate to such
statement. However, if the books and records are not made promptly available
upon request by Tenant, the additional rent for that year shall, in no event, be
deemed due and payable by Tenant. Any dispute shall be subject to arbitration as
provided in Article 20 of the Lease.

     Any amount to be refunded to Tenant under this Exhibit C shall be applied
to the next installments of Base Rent or additional rent hereunder (or paid to
Tenant if there are no such further installments payable by Tenant under this
Lease) and such obligation shall survive the termination, cancellation or
expiration of this Lease.

     Tenant's proportionate share shall be the percentage obtained from a
fraction the numerator of which is the total rentable square feet foot area
leased by Tenant (82,356 rentable square feet for the Office Space and the
rentable square feet for the Storage Area) and the denominator of which is the
total net rentable square foot area of the Building (851,769). In the event
Tenant leases additional space in the Building which are added to the Premises,
Tenant's proportionate share shall be appropriately adjusted.

     If, during any calendar year during the term of this Lease (including the
base year), less than ninety-five percent (95%) of the total net rentable
square footage of the Building is occupied by tenants, the amount of Operating
Expenses for such calendar year shall be deemed to be the amount of Operating
Expenses that, in the reasonable opinion of Landlord's accountant, would have
been incurred if the percentage of occupancy of the Building during such
calendar year were ninety-five percent (95%). For purposes of this paragraph,
the occupancy rate at the Building will be determined on a quarterly basis and
an average occupancy rate computed for each calendar year during the Term, which
average rate will be used for the analysis described herein.

                     EXHIBIT D. REAL ESTATE TAX ESCALATION:

     Tenant agrees to annually reimburse Landlord Tenant's proportionate share
of the amount by which the annual real estate taxes that are levied against the
Building, improvements and the land, in each calendar year beginning with the
calendar year 1999 tax year, exceed the real estate taxes levied in the base tax
year. For the purposes hereof, the "base tax year" sum is the real estate taxes
levied on the Building, improvements and the land for the calendar 1998.

     Any amount due to Landlord under the provisions of this Exhibit D shall be
paid within thirty (30) days after rendition of a bill therefor, together with
submission to Tenant of a receipted tax bill received from the taxing authority
or a copy thereof.

     The tax for any fiscal year in respect to which Tenant is obligated to pay
its proportionate share of an increase in taxes shall be the amount of such
taxes as are finally determined to be legally payable by legal proceedings or
otherwise. In no event shall Tenant be obligated to pay any interest or
penalties imposed upon the Landlord for late payment or otherwise. In no event
shall any reduction in the amount of taxes result in a decrease in the amount of
Base Rent payable under this Lease. Any real estate tax increase or decrease for
any fiscal year during the term of this Lease shall be apportioned so that the
Tenant shall pay or receive its proportionate share of only that portion of the
tax increase or decrease for such year as falls within the term. This provision
shall survive the expiration or earlier termination or cancellation of this
Lease.

     Tenant's proportionate share shall be the percentage obtained from a
fraction the numerator of which is the total rentable square feet leased by
Tenant (82,356 rentable square feet for the Office Space plus the rentable
square feet for the Storage Area) and the denominator of which is the total net
rentable square foot area of the Building (851,769). In the event Tenant leases
additional space in the Building which are added to the Premises, Tenant's
proportionate share shall be appropriately adjusted.

     Tenant agrees to reimburse Landlord its proportionate share as defined
above for any future tax imposed by any municipal, state or federal government
or taxing agency which reduces the rent agreed upon and payable herein. Such
future tax shall only mean a tax upon the real estate such as the land and
Building in which the Premises forms a part. Tenant shall also pay Landlord any
increase in taxes resulting from any alterations or improvements made to the
Premises by Tenant after the initial preparation of the Premises for Tenant's
occupancy.

     If Landlord shall receive any tax refund for any year as the result of any
proceedings undertaken by Landlord for a reduction in the amount of the tax
assessment on the Building or the land, Landlord shall reimburse Tenant, its
proportionate share as described above, to the extent of any such refund, after
deducting any reasonable expenses incurred by Landlord in obtaining such tax
refunds, including, without limitation, reasonable attorney's fees.

Landlord's obligation to so refund to Tenant any such taxes shall survive the
termination of this Lease.

 3.1  Promotion. During the Term and subject to the exceptions set forth in
      ---------
      Section 3.3, Prodigy shall, with respect to Third Party Browsers, use,

      browser technology for the Service.

 3.2  Further Obligations.
      -------------------

      (a)  Download. At Microsoft's option, Prodigy shall provide locations on
           the Service and other Prodigy Sites for End Users and Customers to
           download (either directly or indirectly via URL link) Internet
           Explorer for all Platforms.

      (b)  Promotion On Prodigy Sites. Prodigy shall design its Prodigy Sites as
           premier Internet Explorer sites, including, but not limited to,
           taking advantage of Microsoft's ActiveX technology and using new
           extensions and improvements available in Internet Explorer on sixty
           percent (60%) or more of such sites. Prodigy will choose up to
           fifteen (15) separate features from a list (which is provided by
           Microsoft and which affords Prodigy reasonable choice) and shall
           implement and incorporate such features on the Prodigy Sites, such
           features to be placed within the Prodigy Sites at Prodigy's
           discretion.

           access to, use or downloading of Third Party Browsers on third party
           services and Internet sites, even if accessible through use of
           Service. Prodigy may provide links to use and to download Third Party
           Browsers on or for use with the Service solely at a single Service
           location or Prodigy Site, provided that such locations shall be
           substantially minimized (for example, in a list box) and shall not be

           Section 3.1.

      (b)  Customer  Choice.  Where  expressly  required by a third party  
           provider,  distributor or corporate/organizational account

           by the Customer with the Service; provided, however, that Prodigy 
           shall use all reasonable efforts to minimize the association of 
           "Prodigy" or any Service brand name in connection with such Third  
           Party  Browser(s). The parties will use all reasonable efforts to 
           jointly promote Internet Explorer to any such Customer, including 
           joint meetings of the parties and such Customer.

 3.4  Overall Limitation.  Notwithstanding any exception under Section 3.3, 
      ------------------

                                           Promotion & Distribution Agreement



      each six (6) month period ending June 30 or December 31, during the
      Agreement Term. The initial Semi-Annual Period shall commence upon

      numerator equaling the total number of Third Party Browsers shipped by
      Prodigy under Section 3.3(b), and (ii) the denominator equaling the total
      number of copies of Service Client Software distributed by or for Prodigy
      for the Service.


 4.   DISTRIBUTION OF SERVICE CLIENT SOFTWARE


 4.1  Distribution Obligation. During the Term, Microsoft shall include the
      -----------------------
      Service Client Software as part of each retail package and OEM version of
      Windows 95, including placement of the Desktop and Folder Icons as
      described in Section 4.3, expressly subject to all of the following
      conditions:

      (a)  Latest Version of Internet Explorer. Beginning with version 3.0, for
           each new version of Internet Explorer released by Microsoft during
           the Term as part of a Windows 95 release, Prodigy must integrate and
           incorporate such latest version into the Service Client Software,
           provided that Microsoft has supplied such latest version to Prodigy
           pursuant to this Agreement.

      (b)  Pre- and Final Release Code. Microsoft and Prodigy will use all 
           reasonable efforts to provide to the other alpha and quality beta 
           versions of Internet Explorer and Service Client Software,
           respectively. Such releases will, where possible, be provided within
           ninety (90) days of an expected release to manufacture ("RTM") of the
           recipient's incorporating code. Such ninety (90) day period is not an
           absolute but a guideline, and the parties will use all reasonable 
           efforts to accommodate and work with the other on their respective 
           deliveries of code, including frequent and timely code drops in the
           latter stages of development before RTM.

      (c)  International Distribution. To the extent Microsoft distributes
           Windows 95 in countries where Prodigy does not offer the Service,
           Prodigy must develop a customer referral or notice plan for users
           that access the Service Client Software in such countries, and such
           plan must be approved by Microsoft.

      (d)  Support of Service Client Software. Prodigy understands that each new
           version of Windows 95 requires extensive testing of the entire base 
           of code shipped with the product. Consequently, new versions of the
           Service Client Software to be distributed with corresponding new 
           versions of Windows 95 must be delivered and supported by Prodigy in 
           a timely manner, including: (i) regular alpha and beta code drops 
           shall be given to Microsoft periodically during development with 
           Errors corrected in accordance with the severity schedule and
           procedures set forth in Exhibit D; (ii) final code shall be delivered
           by Prodigy to Microsoft as described in Section 4.1(b); and (iii) 
           following RTM, Prodigy must correct any Errors in accordance with the
           severity schedule in Exhibit D and deliver such corrections to 
           Microsoft. Prodigy shall use reasonable best efforts to ensure that
           the Service Client Software meets Microsoft's performance, quality 
           and size criteria for applications and components shipped with 
           Windows 95. In no event shall Microsoft be obligated to include 
           Service Client Software as part of Windows 95 if the Service Client 
           Software has any Severity 1 or 2 level Error.

      (e)  Support. Prodigy shall handle all Service Client Software support
           issues including, but not limited to, telephone and e-mail support
           for existing and prospective End Users and Customers.

      (f)  Client Size. The Service Client Software shall not exceed one (1)
           megabyte of space, whether on floppy, hard disk or CD-ROM.

      (f)  Setup and Installation Specifications. The Service Client Software 
           must meet the setup and installation specifications set forth in 
           Exhibit C.

 4.3  Folders.
      -------

      (a)  Program Folder. For each version of Windows 95 distributed with the
           Service Client Software as set forth in this Section 4, Microsoft
           shall include the Service Client Icon in the Program Folder. The
           Service Client Icon will be clearly visible whenever the Program
           Folder menu item is opened to its default setting.

      (b)  Desktop Folder. For each version of Windows 95 distributed with the
           Service Client Software as set forth in this Section 4, Microsoft 
           shall include the Prodigy Client Icon in the Desktop Folder. The 
           Prodigy Client Icon will be clearly visible whenever the Desktop 
           Folder is opened to its default setting. Prodigy understands and 
           acknowledges that, separate from the Desktop Folder: (i) Microsoft 
           may have an icon on the Windows 95 desktop that represents a general
           Internet sign-up application or wizard; and (ii) Microsoft may
           continue to place the icon for the Microsoft Network ("MSN") on the 
           Windows 95 desktop or otherwise in Microsoft's sole discretion.

 4.4  Setup & Placement.  Upon setup or installation of Windows 95 with which a
      -----------------
      copy of Service Client Software is distributed:

      (a)  OEM Version. For the OEM version of Windows 95, the default
           installation will place the Desktop Folder containing the Prodigy
           Client Icon on the Windows 95 desktop and install the Service Client
           Software; and

      (b)  Retail Version. For a retail full package or upgrade version of
           Windows 95: (i) for the default installation, the Service Client
           Software and Icon will be installed; (ii) for the portable and
           compact installation, the Service Client Software will not be
           installed, but the Service Client Icon and a small program provided
           by Prodigy for remote installation will be installed in the Desktop
           and Program Folders and, if the End User clicks on such icons, the
           Service Client Software can be installed by the End User from the
           physical media; and (iii) for the custom installation, the Service
           Client Software will, by default, be checked to be installed and will
           not be installed where an End User affirmatively chooses not to so
           install it, in which case the Service Client Icon and accompanying
           small program will be installed as set forth in part (ii), above.

 4.5  Windows 95 Support. Microsoft shall handle all Windows 95 support issues
      ------------------
      including, but not limited to, telephone and e-mail support for existing
      and prospective End Users and Customers.

 4.6  EULA. For versions of Internet Explorer distributed by Prodigy, Prodigy
      ----
      may attach Microsoft's End User License Agreement for Internet Explorer to
      Prodigy's Service member agreement. Prodigy shall obtain Microsoft's
      permission, which permission shall not be unreasonably withheld or
      delayed, for any changes to the installation process of Internet Explorer
      with Prodigy's installation of the Service Client Software distributed
      directly by Prodigy, such as the "suppression" of Microsoft's End User
      License Agreement during installation.

 6.   THIS SECTION INTENTIONALLY OMITTED.


 7.   COSTS; CO-MARKETING

 7.1  Referral Fees. For each Quarterly Period, Prodigy shall pay to Microsoft
      -------------
      a referral fee, as set forth in this Section 7.1, for each subscriber
      which signs up for the Service via the Desktop Folder or Program Folder
      on Windows 95 during the Term.

      (a)  Calculation. The referral fee in a particular Quarterly Period shall
           be calculated as set forth in the chart below.

               Referral fee                       [**]
               ActiveX discount/1/        [**]
               NT/IIS discount/2/         [**]
               FrontPage Extn/3/          [**]

                         ---- 

               Discounted fee                     [**]

               1.  The referral fee shall be reduced by [**] if Prodigy
                   implements "ActiveX" control(s) in the Prodigy's home page
                   for the Service. Prodigy shall notify Microsoft of the
                   ActiveX controls implemented by the Prodigy.

               2.  The referral fee shall be reduced by an additional [**] if:
                   (a) Prodigy uses Microsoft Windows NT and Internet
                   Information Server as the platform for Prodigy's web site
                   that hosts the home page, or (b) Prodigy offers Microsoft
                   Internet Information Server as one of its platforms for Web
                   Hosting services.

               3.  The referral fee shall be reduced by an additional [**] if
                   Prodigy uses Microsoft FrontPage server extensions on
                   Prodigy's web hosting service.

           Prodigy shall pay Microsoft the applicable Referral Fee one-time for
           each "Converted Service Member." For purposes of this Section 7.1, a
           "Converted Service Member" means a new subscriber to the Service
           which subscribed using the Desktop Folder or Program Folder on
           Windows 95 that remains a subscriber with the Service for three (3)
           consecutive months. Microsoft shall be paid only once for each
           Converted Service Member under this Section 7.1(a) regardless of the
           duration of his membership in the Service.

      (b)  Payment. Within thirty (30) days following the end of any Quarterly
           Period, Prodigy shall remit to Microsoft the total referral fees due
           for the immediately preceding Quarterly Period together with a report
           showing the calculation for such fees.

      (c)  Continuing Referral Fees. Unless this Agreement has been terminated
           by Prodigy due to a failure by Microsoft to perform or comply with
           this Agreement, Prodigy shall continue to track and pay referral fees
           to Microsoft as provided above for subscribers who register for the
           Service via the Desktop Folder or Program Folder on Windows 95 for a
           period of one (1) year after the end of the Term.

      (d)  Other Referral Fees. Microsoft acknowledges that Prodigy may pay fees
           similar to the above-mentioned Referral Fees to OEMs. This Agreement
           shall not be construed as limiting in any way whatsoever Prodigy's
           right to make such payments, and such payments shall not be construed
           in any way as abridging Prodigy's obligations under this Agreement.
           Prodigy will

           not owe Microsoft Referral Fees for subscribers to the Service which
           Prodigy obtains other than through the Desktop Folder or the Program
           Folder in Windows 95.

 7.2  Cost Reimbursement. In the event that the parties mutually agree to have
      ------------------
      the Service Client Software included in the floppy diskette versions of
      Windows 95, Prodigy shall reimburse Microsoft for the incremental
      out-of-pocket expense, associated with the inclusion of the Service
      Client Software in such version of Windows 95, including but not limited
      to costs of media, labeling and manufacture and labor costs associated
      with package insertion. Such costs shall be reimbursed by Prodigy on a
      quarterly basis, after receipt of Microsoft's invoice for such costs,
      together with referral fees under Section 7.1.

 7.3  Payment Terms. Any fee or reimbursement due under this Agreement shall be
      -------------
      paid in U.S. dollars.

           payable under this Agreement pursuant to Section 7.1(c), and for one
           (1) year thereafter, Prodigy agrees to keep all usual and proper
           records and books of account and all usual and proper entries

           audit in addition to the amount of any discrepancy.

      (e)  Frequency. Microsoft may exercise its right to audit under this
           Agreement no more than once in any twelve-month period.

 to license, develop, sub-license, manufacture or distribute Internet Explorer 
 or any other technology, for itself or for any third party, or to include third
 party Client Software with Windows 95 generally, or specifically in the Desktop

      incorporation of Internet Explorer into the Service Client Software and
      Service) in any advertising, marketing, technical or other materials
      related to Internet Explorer which are distributed, transmitted or
      promoted by Prodigy or its distributors in connection with this Agreement.
      Such use shall be in accordance with Microsoft's then current trademark
      guidelines to be provided and reasonably updated by Microsoft from time to
      time. If the trademark guidelines are amended or any Microsoft trademarks
      are modified or added, Prodigy shall have the right to deplete or have
      depleted existing and contractually committed for inventories of products
      and materials which may not be in compliance with the amended guidelines
      or modified or added Microsoft trademarks and shall have a reasonable
      transition period to implement compliance. When Prodigy uses a Microsoft
      trademark, Prodigy shall clearly indicate Microsoft's ownership of the
      Microsoft trademark. Prodigy agrees not to register any Microsoft
      trademarks without Microsoft's express prior written consent. Microsoft
      shall promptly notify Prodigy of any claim of infringement or invalidity
      of any Microsoft trademarks or any action or inquiry by any trademark
      office or authority questioning the validity, enforceability or
      registrability of any such Microsoft trademark in any jurisdiction.

      Notwithstanding the foregoing, any fair use by Prodigy of "Microsoft
      Internet Explorer" in a truthful context shall not require Microsoft's
      advance approval unless such use suggests or implies endorsement by
      Microsoft of Prodigy's or any other parties' products or services.

 9.2  Grant by Prodigy. Microsoft is hereby granted a non-exclusive license to
      ----------------
      use those Prodigy trademarks relating to the Service in Windows 95 (to the
      extent incorporated into the Prodigy Icon or Service Client Software) and
      any advertising, marketing, technical or other materials related to the
      Service which are distributed, transmitted or promoted by Microsoft or its
      distributors in connection with this Agreement. Such use shall be in
      accordance with Prodigy's then current trademark guidelines to be provided
      and reasonably updated by Prodigy from time to time. If the trademark
      guidelines are amended or any Prodigy trademarks are modified or added,
      Microsoft and its distributors shall have the right to deplete or have
      depleted existing and contractually committed for inventories of products
      and materials which may not be in compliance with the amended guidelines
      or modified/added Prodigy trademarks and shall have a reasonable
      transition period in which to implement compliance. Microsoft shall
      clearly indicate Prodigy's ownership of the Prodigy trademarks. Microsoft
      agrees not to register any Prodigy trademarks without Prodigy's express
      prior written consent. Prodigy shall promptly notify Microsoft of any
      claim of infringement or invalidity of any Prodigy trademarks or any
      action or inquiry by any trademark office or authority questioning the
      validity, enforceability or registrability of any such Prodigy trademark
      in any jurisdiction. Nothing herein shall require Microsoft to use any
      Prodigy trademark in any manner, except as expressly provided in Section
      4.

      Notwithstanding the foregoing, any fair use by Microsoft of Prodigy's
      trademarks in a truthful context shall not require Prodigy's advance
      approval unless such use suggests or implies endorsement by Prodigy of
      Microsoft's or any other parties' products or services.


10.   CONFIDENTIALITY


10.1  Each party shall protect the other's Confidential Information from
      unauthorized dissemination and use with the same degree of care that such
      party uses to protect its own like information. Neither party will use the
      other's Confidential Information for purposes other than those necessary
      to directly further the purposes of this Agreement. Each party will use
      its best efforts not to disclose to third parties the other's Confidential
      Information without the prior written consent of the other party. Except
      as expressly provided in this Agreement, no ownership or license rights is
      granted in any Confidential Information.

10.2  The parties' obligations of confidentiality under this Agreement shall not
      be construed to limit either party's right to independently develop or
      acquire products without use of the other party's Confidential
      Information. Further, either party shall be free to use for any purpose
      the residuals

       provided that such party shall maintain the confidentiality of the
       Confidential Information as provided herein. The term "residuals" means
       information in non-tangible form, which may be retained by persons who
       have had rightful and good faith access to the Confidential Information,
       including ideas, concepts, know-how or techniques contained therein.
       Neither party shall have any obligation to limit or restrict the
       assignment of such persons or to pay royalties for any work resulting
       from the use of residuals. However, the foregoing shall not be deemed to
       grant to either party a license under the other party's copyrights or
       patents.

13.1  Indemnity by Prodigy.

      (a) Prodigy shall, at its expense and Microsoft's request, defend any
          claim or action brought against Microsoft, and Microsoft's 
          subsidiaries, affiliates, directors, officers, employees, agents and 
          independent contractors, to the extent it is based upon a claim that 
          the Service Client Software, Service Client Icon, and/or Prodigy 
          trademarks licensed under Section 9.2 infringe or violate any patent, 
          copyright, trademark, trade secret or other proprietary right of a 
          third party ("Prodigy Claims"), and Prodigy will indemnify and hold
          Microsoft harmless from and against any costs, damages and fees 
          reasonably incurred by Microsoft, including but not limited to fees of
          attorneys and other professionals, that are attributable to such 
          Prodigy Claims. Microsoft shall:  (i) provide Prodigy reasonably 
          prompt notice in writing of any such Prodigy Claims and permit 
          Prodigy, through counsel mutually acceptable to Microsoft and Prodigy,
          to answer and defend such Prodigy Claims; and (ii) provide Prodigy
          information, assistance and authority, at Prodigy's expense, to help

          permission, which permission will not be unreasonably withheld.

      (b) Prodigy may not settle any Prodigy Claim under this Section 13.1 on
          Microsoft's behalf without first obtaining Microsoft's written
          permission, which permission will not be unreasonably withheld. In

          Prodigy agrees not to publicize the settlement without first
          obtaining Microsoft's written permission, which permission will not
          be unreasonably withheld.

      (c) Prodigy's obligations under this Section 13.1 shall be Microsoft's
          exclusive remedy for any breach of the warranty made by Prodigy
          under Section 11.1(b).

      (a) Microsoft shall, at its expense and Prodigy's request, defend any

          Explorer and/or the Microsoft trademarks licensed under Section 9.1
          infringe or violate any patent, copyright, trademark, trade secret or 
          other proprietary right of a third party ("Microsoft Claims"), and 
          Microsoft will indemnify and hold Prodigy harmless from and against 
          any costs, damages and fees reasonably incurred by Prodigy, including
          but not limited to fees of attorneys and other professionals, that are

          Prodigy and Microsoft, to answer and defend such Microsoft Claims; and

          not be unreasonably withheld.

      (b) Microsoft may not settle any Microsoft Claim under this Section 13.2
          on Prodigy's behalf without first obtaining Prodigy's written
          permission, which permission will not be unreasonably withheld. In

          Microsoft agrees not to publicize the settlement without first
          obtaining Prodigy's written permission, which permission will not be
          unreasonably withheld.

      (c) Microsoft's obligations under this Section 13.2 shall be Prodigy's
          exclusive remedy for any breach of the warranty made by Microsoft
          under Section 11.2(b).

            Integrating Online Services Clients into Windows 95 Setup

                               Contact: John Gray
                           Windows 95 Program Manager

                                Revised: 7/16/96


In order to integrate third party online service client software into Windows 95
setup for preinstalled machines, the Client vendor will should provide setup
files that meet the following requirements.

Files needed by Windows 95 Setup 
Due to limitations on the number of files that Windows 95 can currently copy, we
need the online service to provide a limited number of files that will be copied
to the destination hard disk during setup. Here are the optional install
techniques:
    . Setup "shim" file (xxxSetup.exe) (small) and Kit file (xxxKit.exe) (large)
      - The icon in the OLS folders point to the setup shim file (described 
      below). The kit file is a single, large, compressed, self extracting 
      archive with all of the individual client software files included. The 
      primary purpose of the shim file is to execute the xxxKit.exe file if 
      found and provide alternate behavior if not. It can also handle worldwide 
      distribution issues, and other pre-setup housekeeping chores. The shim 
      setup file will be included inside the ".cab" files for all installations,
      the Kit files will be located outside of the cab files for CD and pre-
      installation purposes. 
      (This is the preferred installation technique for client software 
      deliverables.)
    . Monolithic self installing exe (xxxSetup.exe) - This is the equivalent of
      a single exe file that is downloaded from the Internet to install an
      application. The icon just executes the xxxsetup file. The primary 
      drawback of this technique is lack of error handling for floppy disk SKUs 
      and other cases where the monolithic setup file is not present. The 
      monolithic exe file will not be present inside the .cab files. 
    . Inet Config Wiz signup server files (ISP, .HTM, INS, .ICO) - Online 
      Providers using the Internet Configuration Wizard to access a dedicated 
      signup server just need to provide these small ascii text and icon files.
      Because these are very small, all of them can be located inside the .cab 
      files.

Target Location
All client software files will be installed to the c:\Program Files\Online
Services\xxxx folder, where xxxx should be chosen by the online client vendor to
reasonably identify their product. The short file names for this folder during
setup will be c:\progra-1\online-1\xxxx. Shortcuts to these files will be placed
in the "Online Services" folder on the desktop and on the Start/Programs menu by
Windows 95 setup according to vendor requirements.
    . Note:  Vendor should specify in writing the title of the icons in these 
      two folders when providing binary file drops.

Single EXE Setup
The simplest method to implement an add-on online service client with Windows 95
is to create a single self extracting, setup EXE that can be put in the Windows
95 cab files directory that contains all the individual client files. This exe
file will do the bulk of the client file copying and setup.

Setup "Shim" Program The preferred setup technique is to create a small
"xxxsetup" program launched by the icon in the Online Services folders that will
do the following steps:
     1.  Optional: Query the Locale API or the user to determine if they reside
         in a country that has local access for your client software. If not,
         provide alternative information and exit.
     2.  Required: Look for the Single EXE "kit" setup program described above, 
         in the c:\Program Files\Online Services\xxx folder and execute it
         (possibly with appropriate command line switches)
     3.  Optional: If not found, look for the single EXE "kit" file in the
         "c:\windows\options\cabs" directory. This is used for preinstallation 
         and may contain a copy of your file.
     4.  Optional: If not found, look for the single EXE "kit" file on the 
         Windows 95 CD (or on a network sharepoint) in the Windows 95 Setup 
         directory.  The setup directory can be found in 
         the                following               registry               key: 
         (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SETUP\
         SourcePath)  This may involve prompting the user to insert the CD. 
         Allow the user to cancel if they do not have a CD product or can not 
         find their CD. This is an important step to work properly with compact
         and/or portable installs.
     5.  Required: If still not found, present the user with a dialog box
         indicating that the client software is unavailable, and alternate
         courses of action (e.g. 800 number, www web site, etc.)
The Setup Shim program may also create, rename and delete icons, including the
"setup" icon that called it, upon successful completion. It can also do any
other limited housekeeping or pre-setup configuration work before or after any
of the above steps.

Client Software Requirements
 .  The client software must NOT prompt the user for a certificate, ID or other
   means of tracking marketing information (other than the login userid and
   password for existing accounts.) If you want to collect information on
   specific OEMs, please use the OEMINFO file in the \windows\system directory.
   There is no easy or reliable way to distribute these certificate numbers to
   OEMs end-users. If an end user does not have a certificate, they will not
   sign up for your service. See additional information below about using
   OEMINFO file.
 .  The Client software should (if not already done), eliminate the "setup" icon
   from the two online services folders.
 .  The Client software should install it's own "client" icons ONLY in the two
   Online Services folders. It should not automatically put additional copies of
   it's own icon on the start menu, on the start/programs menu (or submenus), or
   directly on the desktop. It can offer any/all of these additional locations
   during setup, but the default should be to not create these supplemental
   icons. This provides a consistent end-user experience.
 .  Client software binaries should be installed to c:\Program Files\Online
   Services\XXX, where xxx is based on your client software brand name.
 .  Client software should not add or remove any system files, except using
   standard APIs for this purpose. Specifically, no Windows 95 system files
   should be included in the client software deliverables. When integrating with
   a Windows 95 release, you should not need to update or replace any system
   files.
 .  Client software setup program should delete the large monolithic exe or kit
   file at the successful conclusion of setup, to save hard disk space.

Support Information
 .   During setup and/or configuration, your client software should indicate
    that all software support for the client software is provided by your
    company, and not by Microsoft or the PC manufacturer that supplied your
    system.
 .   Help buttons and icons should also clearly indicate that you provide the  
    technical support, and how to contact you. This includes any "Help About" 
    dialog boxes.

Worldwide English Configuration
When your icon/setup program is first run, you will typically ask the user some
configuration questions. The first or second one should be what country they are
in. If you don't have a Point of Presence (telephone number) there, you should
inform the customer and exit gracefully. Microsoft only has one version of
English CD, it gets used worldwide. That means US, Canada, UK, Australia, New
Zealand, India, etc. In addition, the English version of the product is usually
for sale in other countries where there is a localized version available. You
might want to look up the Locale APIs in Win95, they might help out here.

Setup Types 
There are four setup types:
      .   Typical - your monolithic exe will be copied to the hard disk unless 
          specified otherwise in the contract.
      .   Compact - minimal hard disk space usage, your exe/kit file will NOT
          be copied to the hard disk. If a setup shim exists, it will be
          copied.
      .   Portable - same as compact with some portable-specific utilities.
          Large exe/kit files will NOT be copied to the hard disk. If a setup
          shim exists, it will be copied.
      .   Custom - Same as Typical. Custom may offer a checkbox, it will be
          pre-checked but can be cleared by the customer, in which case Large
          exe/kit files will NOT be copied to the hard disk. If a setup shim
          exists, it will be copied.

SKUs
There are four basic OEM products:
      .   End User "OEM Full CD" - this is the same as the retail end-user
          CD, except it will deny upgrading over a Windows 3.1 system. There
          are several minor variants to the OEM Full CD but the differences
          do not affect the Online Services Clients. These are provided to end 
          users when they buy a new system. They are also known as "backup 
          media" because all new PCs come with Windows 95 preinstalled, these 
          are the backups.
      .   End User "OEM DMF" Floppy Disks - these are a subset of the end
          user CD, they contain less files, typically larger, optional
          components such as sound schemes are not present. These are also
          provided to end users, as backup media. Very few OEMs actually use
          this product, however.
      .   MSCSD "Diskettes on the hard disk" disks - the OEM ships the
          contents of the floppy disks on the hard disk. It is then up to the
          end user to use the Microsoft Create System Diskettes tool to make
          their own backup media. Because of the sheer number of floppy
          disks, and time involved many users choose not to make their backup
          media. The collateral material for this SKU includes preprinted
          diskette labels for the end user.
      .   OEM Preinstall ToolKit (OPK) - This is a special CD provided only
          to OEMs, which contains specialized tools and instructions for an
          OEM to integrate Windows 95 preinstalled into a variety of
          manufacturing environments. It is used in conjunction with one of
          the end-user backup media options above. It contains the full
          contents of the OEM Full CD version of Windows 95, including all
          Online Services Clients files.

The first two OEM products above are supplied to Authorized Replicators and
Delivery Service Partners, along with manuals and collateral materials. The Ars
and DSPs then manufacture and sell bulk shrink-wrap prepackaged OEM products to
the OEMs.

RunOnce Preinstallation Options

This section describes optional implementation practices that can improve the
user experience using your client software. However, the implications of these
options must be clearly understood, including the various OEM manufacturing
scenarios, before implementing these features.

It is possible to do some of the file uncompression, copying and configuration
at the factory or before the user takes specific action by clicking on an Icon.
This step will occur during the "RunOnce" phase of setup. This is when the grey
panel on the left side of the screen has a checklist of steps it is performing,
including items like "Configuring MS-DOS programs, Setting up Time Zone,
Configuring Windows Messaging, Setting up Help, etc." To do this, you need to
have either the setup shim exe or the monolithic setup exe meet meet the
following requirements:

      .    No UI - no progress bars, no blue backgrounds, no questions, no
           stops for any reason, totally silent, all defaults assumed. A
           command line switch is acceptable to invoke this option.

      .    Must be able to be run during "1st Boot - RunOnce". This means that 
           some system services and hardware may not be fully configured, 
           including Dial Up Networking. It should be able to find it's files  
           either in the single file on the hard disk or in a directory on the 
           CD. You can look in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\
           CurrentVersion\SETUP\SourcePath to find the setup UNC or Drive 
           Letter/directory. (Should your runonce setup not find your files,  
           it should fail gracefully & silently). Note that you should handle 
           either UNC path names or drive/directory path names.

      .    For Minimal Install, we will not call your app, instead it will be
           called when the user clicks on your Icons in the online folder. At
           this point, your usual UI can run, and ask the user any questions.

You can find some general information on OEM Preinstalling at:

           http://www.microsoft.com/win32dev/guideIns/preinstl.htm.
This document is designed for apps that the OEM will merge in their factory, in
our case we're doing it on the CD but the information can still be valuable to
you. Runonce has similar requirements to the non-hardware file copy section.

OEMINFO.INI Info

OEMs are required by the preinstallation toolkit to create a simple ASCII text
INI file in the c:\windows\system directory named OEMINFO.INI. This file will
always contain a section:

    [general]
    manufacturer=Acme PC Manufacturing

where the manufacturer name is a string entered by the PC manufacturer. It also
can contain additional sections added by the OEM. The manufacturer name is
displayed when you view the System control panel (properties of "My Computer").

This file will only be present on preinstalled machines, it will not be present
on systems that have had the disk formatted and reinstalled from the backup
media. If you want to add additional certificate info for your client to upload,
you can add a section name yourself, with several lines of defined text (you
would replace XXX with a unique identifier based on your client software name):

    [XXX]

    variable 1=whatever you want

    variable 2=whatever you want also

You should properly handle error conditions in the event this file does not
exist, or your private section is not present. At no time should you prompt the
end user for certificate information.

Microsoft will respond as follows to each problem report, based on the Severity.
       Note that, as Microsoft nears a product ship deadline, the criteria for a
       "showstopper" problem (must fix before ship) get harder and harder to
       meet. Microsoft also reserves the right to reclassify the Severity of a
       problem report from Prodigy if it does not meet, in Microsoft's
       professional judgment, the Severity classification described above.

 Prodigy will respond as follows to each problem report, based on the Severity.
      Note that, as Prodigy nears a product ship deadline, the criteria for a
      "showstopper" problem (must fix before ship) get harder and harder to
      meet. Prodigy also reserves the right to reclassify the Severity of a
      problem report from Microsoft if it does not meet, in Prodigy's
      professional judgment, the Severity classification described above.

     Company acknowledges and agrees that its use of the IEAK to customize 
     Internet Explorer version 4.0 and Outlook Express version 4.x requires the 
     rightful receipt from Microsoft of the License Key allocated to Company. 
     Company agrees that it shall only use the IEAK in accordance with the 
     Instructions. In the event the capabilities and/or instructions of the IEAK
     are in conflict, either by providing more or fewer capabilities than the 
     customization rights granted in Sections 2(b) of this Amendment, the 
     customization rights granted in Section 2(b) of this Amendment shall have 
     precedence.

(b)  Permitted Customizations.
     ------------------------

     (a)  Channel Customization. For versions 4.0 of Internet Explorer which
          support Channels, Company may use the applicable IEAK to perform
          the any or all of the following additional customizations with
          respect to Channels (as further illustrated in Attachment A-l)

                (i)  Add a single Company Channel Icon to the topmost
                     navigation level of the Internet Explorer Channel bar in
                     the position below the Microsoft Channel Guide Icon.
                     Said Icon may link either to Company or third party
                     Channel available through Internet Explorer, provided
                     that any trade names, trademarks, logos or brands
                     displayed on the Channel Icon added by Company shall be
                     limited to Company's mark or Company's Internet Product
                     marks. Company may add multiple "sub-channels" grouped
                     underneath (at the second navigation level) the Company
                     Channel Icon on the Internet Explorer Active Desktop
                     channel bar, where each such sub-channel may be linked
                     to Company or third-party Content accessible through
                     Internet Explorer, and where each such sub-channel may
                     use any branding selected by Company.

                (ii) Add multiple Additional Company Channel Icons to the
                     topmost navigation level of the Internet Explorer Active
                     Desktop Channel bar in the position below the Company
                     Channel Icon, where each such Additional Company Channel
                     must be linked to Company Content which: (a) an end user
                     must pay a fee to Company for access; and (b) is not
                     available over the open Internet, or must be protected
                     behind a firewall such that a password or other
                     authentication by an end user is required for access.
                     Company may add multiple "sub-channels" grouped
                     underneath (at the second navigation level) the
                     Additional Company Channel Icon(s) on the Internet
                     Explorer Active Desktop channel bar.



                                                                    Page 2 of 6

                                                   IE4 Referral Server Amendment



In the case where sub-channels are grouped underneath a Company Channel Icon or
an Additional Company Channel Icon, the Company Channel is the only Channel
which is individually recognized by IE; the sub-channels do not operate as
separate Channels by themselves (and cannot be subscribed separately using the
IE4 UI).

          (iii)  Configure the Company Channel added by Company to be
                 "subscribed" by default, such that Company Channel Content and
                 schedule information downloads to the end user's computer
                 system hard disk automatically when the end user connects to
                 the Internet and selects the "update" option.

          (iv)   Delete from the Internet Explorer Active Desktop Channel bar
                 any pre-configured Channel Icons that are developed or
                 distributed by companies which compete directly with Company,
                 where such deleted Channels are to include only: (i)
                 preconfigured Channels from other Internet access providers,
                 (ii) pre-configured Channels which are produced by, or
                 exclusively distributed by, direct competitors of Company, or
                 company authored content. Company may not delete a
                 preconfigured Channel Icon that offers Content which is not
                 directly competitive with Company or Company's Content but that
                 may nonetheless compete for the end users' attention or
                 interest with Content offered by Company.

(b)       Selection of Pre-Configured Channels. For versions 4.0 of Internet
          Explorer which support Channels, Company shall use the IEAK to select
          the pre-configured Channels for the specific territory for which each
          and every Company-customized version of IE is targeted for
          distribution. For example, if Company customizes separate versions of
          IE for distribution into territories A and B, Company shall use the
          IEAK to select the pre-configured default Channels for territory A for
          the version of IE Company creates for territory A, and shall use the
          IEAK to select the pre-configured default Channels for territory B for
          the version of IE Company creates for territory B. For the purposes of
          this paragraph, "territory" shall mean a language/country combination,
          such as German/Switzerland or French/Canada.

(c)       Internet Explorer Features. For any Channel added by Company pursuant
          to Section (a) above, Company agrees to use reasonable commercial
          efforts to develop and maintain said Channel such that it demonstrates
          the advanced features of Internet Explorer (including Dynamic HTML,
          etc.) and meets end user expectations of performance and frequency of
          update such that Company's Channel compares favorably, in Company's
          reasonable judgment, to Channels offered by other companies in
          Company's line of business.

(d)       Use of Standard Redistribution Key. For version 4.0 of Internet
          Explorer, Company may use the applicable IEAK and the IEAK
          Customization Wizard with the "Standard Redistribution" key
          capabilities of the Wizard to perform any or all of the following
          customizations:

               its installations for the Licensed Software, then any

               option offered in the IEAK. In addition, Company may also include
               the "Standard" and/or "Minimal" installation options as described
               in the Instructions. Company may not exclude any Licensed
               Software component from an installation.

                 installation and (ii) Company may add its own components and
                 options to such installation; provided, however, in no event

accepts from Prodigy during the Term, subject to the terms and conditions
contained herein, a non-exclusive license ("License"):

     2.1.1   to pre-install a copy of the most current version of the Software
     provided by Prodigy hereunder on the hard disk of certain of PC
     Manufacturer's computers (each such computer onto which the Software has
     been installed pursuant to this Agreement being a "Computer" and which may
     include PC Manufacturer's computers sold under the NEC, Zenith Data Systems
     and Packard Bell labels and any other labels agreed to by Prodigy) by

     countries in which access to the Service is available locally;

                                      -2-
<PAGE>
 
     2.1.3   to use and reproduce the "Prodigy(R) Internet mark, together with
     such other trademarks and service marks of Prodigy or third parties
     attached hereto as Attachment A (collectively, the "Trademarks"); and

     2.1.4   to sublicense the Software to Third Party Distributors solely to
     grant to such Third Party Distributors the right to market and distribute
     the Software as included in Packages in accordance with Section 2.1.2, and
     to sublicense to Third Party Distributors the right to use the Trademarks
     solely in accordance with Section 2.1.3, all in accordance with the terms
     and conditions set forth in this Agreement. For purposes of this Agreement,
     a "Third Party Distributor" shall mean any entity who has the right,
     pursuant to an agreement with PC Manufacturer that complies with and is
     consistent with the applicable terms and conditions of this Agreement, to
     distribute Packages to the public. The terms and conditions stated in this
     Agreement shall apply to all sublicenses made hereunder during the Term.

any time, to modify any technical specifications or other technical matters
relating to the installation and/or operation of the Software, including the
hardware requirements for Computers, or other technical specifications or
matters relating to the Software that affect the operation of the Software on
Computers.  PC Manufacturer shall not be obligated to start installing any
updated or new Software on Computers until its next major product launch, unless
Prodigy requests PC Manufacturer to commence installation of an updated or new
Software prior to PC Manufacturer's next major product launch because the then
current version of the Software contains material that infringes or may infringe
the rights of a third party. Major product launches normally occur every six to
eight months.

                                      -3-

following the end of any trial offer period provided by Prodigy.  Each Converted
Membership Holder shall be counted only once under this Section 3.5 regardless
of the duration of his/her membership in the Service.  Notwithstanding anything
in this Agreement to the contrary, (i) a Converted Membership Holder does not
include members of the Prodigy Classic Service ("Prodigy Classic," which is
another interactive, information, communication and transaction service offered
by Prodigy) who choose to convert their membership from Prodigy Classic to
Prodigy Internet or who maintain their Prodigy Classic membership and enroll in
Prodigy Internet, as well; (ii) a Member cannot become a Converted Membership
Holder on or after the effective date of termination of this Agreement,
regardless of any reason for such termination, unless the Agreement is
terminated for breach by Prodigy, in which case a Member may become a Converted
Membership Holder for six months after termination and Prodigy will pay PC
Manufacturer the amounts listed below for each such Converted Membership Holder;
(iii) Prodigy will not owe PC Manufacturer any fee for any person or entity who
becomes a Member using any registration mechanism other than the Documentation
specially coded to identify PC Manufacturer; and (iv) the fee payable by Prodigy
hereunder is limited to one Converted Membership Holder per household,

acknowledge that Agreement No. 6102 between Prodigy and NEC Technologies, Inc.,
dated June 23, 1995 (the "NEC Contract") commenced in 1995, and hereby agree to
terminate the NEC Contract, effective December 31, 1996. Notwithstanding the

to pay PC Manufacturer the amount set forth in 

                                      -5-

Prodigy, for one month of Prodigy Classic membership following the end of any
trial offer period provided by Prodigy. Each Prodigy Classic Converted
Membership Holder shall be counted only once under this Section 3.6 regardless
of the duration of his/her membership in Prodigy Classic. Payments to PC

during the period from January 1, 1997 through December 31, 1997 Prodigy and PC
Manufacturer acknowledge that Agreement No. 3744 between shall be payable as

     Contract for each such Prodigy Classic Converted Membership Holder who
     became a Prodigy Classic Converted Membership Holder under the Classic
     Contract and (b) the amount set forth in the NEC Contract for each such
     Prodigy Classic Converted Membership Holder who became a Prodigy Classic
     Converted Membership Holder under the NEC Contract.

     3.6.2   No later than January 31, 1998, Prodigy will report to PC
     Manufacturer the number of Prodigy Classic Membership Holders who have
     become Prodigy Classic Converted Membership Holders between July 1, 1997
     and December 31, 1997, and pay to PC Manufacturer (a) the amount set forth
     in the Classic Contract for each Prodigy Classic Converted Membership

     Classic Contract and (b) the amount set forth in the NEC Contract for each
     such Prodigy Classic Converted Membership Holder who became a Prodigy
     Classic Converted Membership Holder under the NEC Contract.

3.7  Prodigy shall provide PC Manufacturer during the Term of this Agreement
continued access to its server to allow purchasers of PC Manufacturer's
computers the ability to register the warranty associated with their computer
online through Prodigy's 800 number.  Prodigy shall download the purchaser's
data information and forward it to PC Manufacturer.  Prodigy shall filter the
names of the purchasers of the PC 

                                      -6-
<PAGE>
 
Manufacturer's computers who complete the warranty registration process online,
which it obtains from PC Manufacturer, to eliminate the names of those
purchasers who are already enrolled in the Service. Prodigy may then use the
remaining names to issue direct mail, encouraging the purchasers to enroll in
the Service, and for no other purpose.

3.8   Subject to the following sentence, Prodigy shall provide to PC
Manufacturer on a quarterly basis during the Term of this Agreement the email
address of each Converted Membership Holder, except for those Converted
Membership Holders about whom Prodigy does not release information based on
Prodigy's privacy policy, customer agreement and email etiquette policy in
effect at the time of delivery. The date of commencement of Prodigy's
obligations under this Section 3.8 and the details concerning Prodigy's
obligations and PC Manufacturer's rights with respect to the manner and
frequency of use of the information provided by Prodigy shall be set forth in an
addendum to this Agreement to be negotiated in good faith by the parties hereto.

3.9   The parties acknowledge that this Agreement does not preclude either party
from entering into bounty-type agreements for membership acquisition similar to
this Agreement with other entities, including other personal computer
manufacturers or online service providers and competitors of PC Manufacturer or
Prodigy.

3.10  Each statement provided by Prodigy under Sections 3.5 and 3.6 above shall
be deemed to have been accepted by PC Manufacturer unless PC Manufacturer
provides Prodigy with written notice, objecting to the statement, embodying,
with specificity, the reason or reasons for the objection within one (1) year of
the date such statement is due. Provided PC Manufacturer provides such written
notice of objection as set forth above, upon at least fifteen (15) days' written
notice, PC Manufacturer may conduct an audit on its behalf by an independent
certified public accountant of Prodigy records pertaining solely to this
Agreement.  Such audit shall be conducted by an independent certified public
accountant, of PC Manufacturer's choosing, subject to Prodigy's reasonable
approval, and which is not then conducting an audit of Prodigy's books for any
other person, firm or corporation, during normal business hours and not more
than once per year and shall review the immediately preceding one year period
only.  The cost of the audit shall be borne by PC Manufacturer; provided,
however, that should any audit reveal the amount paid by Prodigy to PC
Manufacturer pursuant to this Agreement for any year has been understated by
more than five percent (5%) of the amount actually owed, then the reasonable
cost of such audit, shall be paid by Prodigy.  Within 30 days after completion
of an audit, PC Manufacturer shall provide Prodigy with a copy of the audit
report and, if there is a discrepancy between the amount owed and the amount
actually paid by Prodigy during the audited period, the party benefited by such

                                      -7-
<PAGE>
 
discrepancy shall reimburse the other party for the difference not later than
thirty (30) days following delivery of the audit report to Prodigy.  Any action
to be commenced in connection with such audit must be commenced within two years
of the date each statement is due.

4.   OBLIGATIONS OF PC MANUFACTURER.

4.1  PC Manufacturer shall provide to Prodigy, for a reasonable period, a
representative sample of each of its computer configurations onto which it
intends to copy the Software, to ensure proper functioning of the Software and
Service in conjunction with such computers.  Prodigy shall have the right to
reject those configurations on which the Software and/or Service does not
function properly, provided that PC Manufacturer will reasonably cooperate with
Prodigy to determine if modifications are feasible to the Software and/or the
Computers to resolve the non-functionality.

4.2  PC Manufacturer shall provide to Prodigy a representative sample of each
new Computer on which the Software is installed on loan for ninety (90) days as
soon as the Software is installed and testing commences, prior to general
shipment, to enable Prodigy to test the Software as installed on the Computer.
After the ninety (90) days have expired, Prodigy will either return the Computer
or purchase it, at cost, at Prodigy's option.

When PC Manufacturer develops a new hard drive (rather than a new machine), so
that the hard drive is reconfigured with a new format, PC Manufacturer will
supply Prodigy with a sample of the new hard drive as soon as it is available,
to enable Prodigy to test the Software on the new hard drive.  Prodigy will
return the old hard drive to PC Manufacturer after receipt of the new hard
drive.

4.3  PC Manufacturer will cooperate with Prodigy in testing the Software on the
Computers.  PC Manufacturer shall meet with Prodigy quarterly, commencing with
the Effective Date of this Agreement, (a) to exchange technology information and
updates which may affect the other parties' product; and (b) to develop mutually
beneficial marketing strategies.

4.4  Except as indicated above, PC Manufacturer will install the most current
version of the Software provided by Prodigy onto the hard drive of only those
Computers approved by Prodigy as described above prior to shipment of such
Computers for sale to any third party, including retailers, distributors, and
end-users, such copies to be used 

                                      -8-
<PAGE>
 
solely as described in this Agreement. Nothing in this Agreement shall prevent
PC Manufacturer from selling computers without the Software.

4.5  Subject to Prodigy's right of prior approval set forth in Section 7 below,
PC Manufacturer shall include specific reference to the Service: (i) by using
the Service logotype or other reference to the Service as approved by Prodigy,
in PC Manufacturer's retail sales training program.  PC Manufacturer will
provide a link from an appropriate area on its Web site to a Prodigy promotional
page on Prodigy's server.

4.6  PC Manufacturer shall include a copy of the Insert, if provided by Prodigy,
with each Computer.  Notwithstanding anything to the contrary contained herein,
PC Manufacturer shall not be required to do anything, which, in its reasonable
judgment, could cause the amount of money which it is otherwise eligible to
receive under Intel's marketing development program to be reduced or eliminated.

4.7  Commencing with the first month after the Effective Date, by the fifth
(5/th/) business day of each month, PC Manufacturer shall provide to Prodigy its
twelve (12) month rolling forecast, including the number and types of computers
on which PC Manufacturer plans to install the Software and ship in that upcoming
period to enable Prodigy to provide PC Manufacturer with Inserts and other
promotional materials, as agreed to by the parties hereto, on a timely and cost-
efficient basis and to develop marketing plans.  By the fifth (5/th)/ business
day of each month, PC Manufacturer shall report to Prodigy the number of
Packages shipped from its manufacturing facilities during the preceding month.
Both the forecasts and reports to be provided by PC Manufacturer under this
Section 4.7 shall be deemed to be Confidential Information. Prodigy acknowledges
that Packard Bell cannot and does not guaranty that any such forecast will
accurately reflect the number of Packages which it will ship and Prodigy
acknowledges that Packard Bell makes no representation regarding the number of
customers which will become Members or Converted Members.

4.8  PC Manufacturer shall supply Prodigy on a quarterly basis a file
identifying the names of the purchasers of PC Manufacturer's computers who
completed PC Manufacturer's warranty registration process online.  Prodigy may
use those names for marketing purposes as described in Section 3.7 above.

5.   OWNERSHIP AND PROPERTY RIGHTS.

5.1  PC Manufacturer acknowledges that each Trademark is and shall remain the
exclusive property of Prodigy or the applicable third-party owner, and all use
by PC Manufacturer of any Trademark shall inure solely to the benefit of Prodigy
or such 

                                      -9-
<PAGE>
 
third-party owner, as applicable. Neither this Agreement nor the License granted
hereunder shall operate as a transfer to PC Manufacturer of any rights in or to
any Trademark, except for the limited rights expressly granted under the
License. PC Manufacturer shall not take any action that would undermine,
conflict with, or be contrary to the rights and interests of Prodigy and/or any
applicable third-party owner of any Trademark, including, without limitation,
any use of, or attempt to register, any trademark, service mark, or trade name
confusingly similar to any Trademark.

5.2  It is expressly understood and agreed that no title to, or ownership of,
the Software provided on any Master Disk, or any part thereof, is hereby
transferred to PC Manufacturer, and that title thereto is and shall remain the
property of Prodigy; and that all applicable copyrights, trade secrets, patents
and other intellectual property rights in the Software and all other items
licensed hereunder are and shall remain the property of Prodigy.  PC
Manufacturer shall not remove any copyright notices or other proprietary
markings from any Master Disk or any copies of the Software distributed by PC
Manufacturer.

6.   CONFIDENTIALITY.

6.1  Either party hereto may disclose to the other party certain information
that the party deems confidential.  As used in this Section, "Confidential
Information" means all information, regardless of the form in which it is
transmitted, relating to the disclosing party's business which, if disclosed in
tangible or electronic form, bears a legend indicating that it is confidential
information or if disclosed orally or visually only, is defined as confidential
or proprietary at the time of disclosure and is promptly thereafter summarized
in a non-confidential memorandum to the receiving party.  For a period of three
(3) years from the date of disclosure, the receiving party shall not disclose
any Confidential Information it receives from the other party to any person,
firm or corporation except to:

(a)  its employees of Recipient and employees of its affiliated companies who

latent or patent, (b) actual or alleged construction or design of such Computer
or other product, or (c) failure to comply with any specification or express or
implied warranty of PC Manufacturer as respects any such Computer disk or other

governed by and construed in accordance with the laws of the state in which the

          of the following: PC Manufacturer's breach of any of PC Manufacturer's

         [Confidential Materials omitted and filed separately with the

           EXCITE SERVICES DISTRIBUTION AND CO-BRANDED AREA AGREEMENT

This agreement ("Agreement") is entered into as of the 20th day of January, 1998
("Effective Date"), by and between Excite, Inc., a California corporation,
located at 555 Broadway, Redwood City, California 94063 ("Excite"), and Prodigy
Services Corporation, a Delaware corporation, located at 44 S. Broadway, White
Plains, New York 10601 ("Distributor").

                                    RECITALS

A. Excite maintains a site on the Internet at http://www.excite.com (the "Excite
   Site'") and owns and/or manages related Web sites worldwide (collectively,
   the "Excite Network") which, among other things, allows its users to search
   for and access content and other sites on the Internet.

B. Within the Excite Site. Excite currently organizes certain content into 
   topical channels ("Excite Channels"), including a personalized Internet
   information service known as "My Channel".

C. Distributor provides interactive information, communication and transaction
   services through, among other delivery platforms, the Prodigy Internet
   service ("Prodigy Internet"), an Internet-based service, and the Prodigy
   Service ("Prodigy Classic"), an online service, for use by any individual,
   business, or entity now or hereafter authorized by Distributor to use Prodigy
   Internet or Prodigy Classic or both ("Prodigy Internet Subscribers" or
   "Prodigy Classic Subscribers," as applicable, and together referred to as
   "Distributor's Subscribers"). For purposes of this Agreement, unless
   otherwise stated, Prodigy Internet Subscribers and Distributor's Subscribers
   do not include Non-Excite Subscribers, as defined in Section 3(c) below.

D. Excite and Distributor wish to promote Excite's Internet search, navigation
   and content services to certain of Distributor's Subscribers. Excite and
   Distributor desire that Excite design, maintain and operate co-branded
   versions of its search, navigation and content aggregation services, to
   promote such co-branded services to certain of Distributor's Subscribers and
   to share revenue derived from their use.

Therefore, the parties agree as follows:

1. CO-BRANDED EXCITE SERVICES

   a)  Excite will design and create Web pages ("Co-Branded Pages" or,
       collectively, the "Co-Branded Area") for Excite Search, Excite Channels
       and My Channel services which will prominently display the name and/or
       brands of both Distributor and Excite.

                                       1
<PAGE>
 
   b)  Excite and Distributor will collaborate and mutually agree upon the
       appearance, content and user interface of the Co-Branded Pages.

   c)  The Co-Branded Pages will conform to the product description attached
       hereto as Exhibit A. This product description may be changed by the
       mutual agreement of the parties.

   d)  The Co-Branded Area will reside and be hosted on Excite's servers,
       similar to those used for Excite's generally available services on the
       Excite Site. Excite will have sole responsibility for providing and
       maintaining at its expense, the Excite Site, the Co-Branded Area and
       Excite's servers.

   e)  Distributor may request reasonable revisions to the Co-Branded Pages.
       Excite will use reasonable efforts to accommodate Distributor's 
       requested changes within three (3) days, but in no event later than
       fifteen (15) days, after receipt of Distributor's request.

   f)  Distributor will have the right to replace individual top-level. Excite
       Channels with channels specified by Distributor if;

       i)  Excite Channel content is not among the top three "best of breed"
           choices. To be among the best of breed choices requires that Excite
           content will at all times be at least comparable to any other source
           of similar topical content available on the Internet in terms of the
           following factors, taken as a whole; (i) breadth and depth of
           coverage; (ii) timeliness of content updates; and (iii) reputation
           and ranking based on a cross-section of third-party reviewers in
           terms of features, functionality, quality and other qualitative
           factors. In the event that an Excite Channel fails to meet these
           quality criteria, Distributor may request that Excite remedy the
           deficient factor(s) within forty-five (45) days or, if Excite is
           unable or unwilling to provide remedy, that Excite supplement the
           Excite Channel with another channel containing content designated by
           Distributor (a "Non-Excite Channel") on forty-five (45) days' written
           notice to Excite; and

       ii) Excite maintains a minimum of eighty percent (80%) of its existing
           channel structure after the inclusion of any Non-Excite Channel. The
           existing channel structure is defined as the selection of main
           channel links located on the start page of the Excite Site.

   g)  Distributor may select up to two (2) subchannels containing content
       designated by Distributor (a "Non-Excite Subchannel") for inclusion on
       any top-level Co-Branded Channel Pages upon mutual agreement so long as

                                       2
<PAGE>
 
         [Confidential Materials omitted and filed separately with the
       Securities and Exchange Commission. Asterisks denote omissions.]

 
       the Distributor selection is not in conflict with then existing Excite
       relationships. Examples of conflicts include, but are not limited to,
       cases where Excite has contractual agreements to provide exclusive or
       premier placement for certain content.

   h)  Excite agrees that it will not sell, lease, barter, or give away to third
       parties the name, telephone number, email address, residential address,
       office address, and/or fax number of any of Distributor's Subscribers
       without Distributor's written consent. Excite further agrees that it will
       not send unsolicited email messages or other unsolicited communications
       to Distributor's Subscribers without Distributor's written consent.

   i)  Excite will make reasonable commercial efforts to provide a co-branded
       version of the MailExcite free email service ("Co-Branded Mail") to
       Distributor's Subscribers of the Co-Branded Area. Prodigy Internet
       Subscribers who register for Co-Branded Mail will be given an email
       address which uses the domain name of "prodigyweb", or other domain name
       specified by Distributor prior to the launch of the Co-Branded Mail. The
       selection of a domain name other than "prodigyweb" will be subject to
       prior approval by Excite, such approval not to be unreasonably withheld.

   j)  Excite will provide Distributor with five additional versions of the top-
       level page of the Co-Branded My Channel ("OEM Pages"), as specified in
       Exhibit A at no expense to the Distributor. At Distributor's request,
       Excite will provide additional OEM Pages to Distributor at a cost of [**]
       per OEM Page.

2. COMMUNITY SERVICES AND APPLICATIONS

   a)  Excite will create up to fifty chat rooms to be made available as needed
       for the use of Distributor's Subscribers on topics to be specified by
       Distributor ("New Chat").

   b)  Excite will create up to one hundred message boards on topics to be
       specified by Distributor ("New Boards").

   c)  Excite will maintain and monitor the New Chat and New Boards referred to
       in Sections 2(a) and 2(b), above, at a level of service comparable to
       that provided on the Excite Site at the Effective Date of this Agreement.

   d)  Excite will create co-branded versions of the following applications
       ("the Co-Branded Applications") for use by Prodigy Internet Subscribers:
       (i) Excite PAL "buddy list" and (ii) client and Java versions of Excite's
       chat application.

3. LINKS TO THE CO-BRANDED EXCITE SERVICES

   a)  Distributor will incorporate the Co-Branded My Channel service as the
       default home page for Prodigy Internet Subscribers, except as provided in
       Section 3(f) below.

   b)  Distributor will be free to distribute versions of Prodigy Internet with
       OEM or affinity partners which do not include the Co-Branded My Channel
       service ("Non-Excite Versions") should such partner so desire, subject to
       Section 3(d), below.

   c)  Subscribers to Non-Excite Versions ("Non-Excite Subscribers") will not be
       classified as Prodigy Internet Subscribers.

   d)  At the end of any calendar month, Non-Excite Subscribers will not account
       for more than 25% of the sum of: (i) total Prodigy Internet Subscribers
       and (ii) Non-Excite Subscribers.

   e)  The co-branded version of Excite Search will be the exclusive Internet
       search service promoted by Distributor to Distributor's Subscribers.

   f)  At Distributor's option, Distributor may provide a default start page for
       Prodigy Internet Subscribers which is not a Co-Branded Page, provided
       that Distributor will incorporate the Co-Branded Area as the exclusive
       personalized service and Internet search and navigation service
       applications provided to Prodigy Internet Subscribers in the following
       manner:

       i)   Distributor will display links to the co-branded versions of Excite
            Search, Excite Channels and My Channel services "above the fold" on
            the home page of Prodigy Internet. Any such home page(s) will exist
            or be maintained at Distributor's sole discretion. For purposes of
            the Agreement, "above the fold" means the area visible to a user
            viewing the default home page of Prodigy Internet using a standard
            Web browser without having to scroll up or down, or to the right or
            left, while viewing a standard screen size (e.g., a VGA display of
            640 x 480 pixels) on a standard computer monitor.

       ii)  If such change in presentation requires engineering or design
            changes by Excite, Distributor will use best efforts to provide as
            much advance notice of the required change in presentation as is
            practicable.

       iii) If, pursuant to Subsection (f) above, Distributor provides a default
            start page for Prodigy Internet Subscribers which is not a Co-
            Branded Page, and fewer than fifty percent (50%) of Prodigy Internet

                             Prodigy Confidential

         [Confidential Materials omitted and filed separately with the
       Securities and Exchange Commission. Asterisks denote omissions.]

 
            Subscribers regularly access My Channel within three (3) months
            following such implementation, Excite will have the right to
            terminate the Agreement.

       iv)  Excite may request reasonable revisions to the link(s) to the
            CoBranded Area. Distributor will use reasonable efforts to
            accommodate Excite's requested changes within fifteen (15) days of
            receipt of Excite's request.

       February 27, 1998 (the "Phase I Implementation Date").

   b)  Distributor and Excite will make best efforts to implement a test version
       of the additional product features specified under Phase II in Exhibit A

       Distributor and Excite will make best efforts to implement a final

       Exhibit A by March 17, 1998, but in no event later than April 3, 1998
       (the "Phase II Implementation Date").

5. ADVERTISING AND REVENUE SHARING

   a)  Excite will be solely responsible for selling advertising on the Co-
       Branded Pages and the Excite Site, except for Non-Excite Channels and 
       Non-Excite Subchannels.

   b)  Within thirty (30) days of the end of each calendar month during the term
       of the Agreement, Excite will make payment to Distributor (the
       "Distributor Payment") resulting from advertising on the Co-Branded
       Pages. For each calendar month, the Distributor Payment will be
       calculated as [**] during the calendar month and [**] during the calendar
       month.

       banner advertising sales on the Excite Network less: (i) Excite's sales

<PAGE>
 
         [Confidential Materials omitted and filed separately with the
       Securities and Exchange Commission. Asterisks denote omissions.]

       and commissions will in no event exceed [**] of total revenue generated
       from banner advertising sales on the Excite Network.

   d)  The Distributor Portion for a given calendar month will be defined as the
       product of: (i) 0.5 ("the Split") and (ii) total page views generated on
       the Co-Branded Area, excluding page views generated in conjunction with
       the Co-Branded Applications and Co-Branded Mail, for a given month
       divided by total page views generated on the Excite Network during the
       same month, including the Co-Branded Area but excluding page views
       generated in conjunction with Excite PAL, chat applications and
       MailExcite. (For purposes of illustration, see Exhibit D attached
       hereto.)

   e)  Excite will calculate the Distributor Payment for each calendar month
       during the term of the Agreement and make payment to Distributor within
       thirty (30) days of the end of each calendar month.

   f)  With each payment, Excite will provide to Distributor documentation
       reasonably detailing the calculation of the payment,

   g)  Excite will maintain accurate records with respect to the calculation of
       payments due under the Agreement. Distributor may, upon no less than
       thirty (30) days prior written notice to Excite, cause an independent
       certified public accountant to inspect the records of Excite reasonably
       related to the calculation of such payments during Excite's normal
       business hours. The fees charged by such certified public accountant in
       connection with the inspection will be paid by Distributor, unless the
       payments made to Distributor are determined to have been less than ninety
       percent (90%) of the payment owed to Distributor, in which case Excite
       will be responsible for the payment of the reasonable fees for such
       inspection. In addition, if the audit reveals any underpayment between
       the amount owed and the amount actually paid by Excite during the audited
       period, Excite will correct the underpayment by paying Distributor the
       amount of such underpayment.

   h)  Excite will make reasonable commercial efforts to exclude advertising
       from the Co-Branded Pages and the Co-Branded Applications from up to ten
       (10) advertisers as specified by Distributor in Exhibit E. [**].
       Not more than four times per calendar year, Distributor may update this
       list of advertisers. Within two (2) business days of receiving
       Distributor's written update, Excite will remove any advertising from
       such advertisers from the Co-Branded Pages and Co-Branded Applications.

   i)  Nothing herein shall be deemed to prohibit Excite from promoting its own
       services via banner advertising in the Co-Branded Pages, except in
       connection with promotions of any advertiser listed in Exhibit E.

6. PROMOTION OF THE CO-BRANDED AREA AND EXCITE SERVICES

            display any "above the fold" or graphic links to any of Excite's
            competitors, including, but not limited to, Alta Vista, HotBot,
            InfoSeek, Lycos, Search.com, Snap! or Yahoo!, or any other Web site
            promoting itself as a provider of internet search and navigation
            services.

       ii)  Excite NewsTracker will be the exclusive personalized Internet news
            clipping service on all web pages controlled by Distributor and
            provided to Prodigy Internet Subscribers in which Distributor
            displays links to a personalized internet news clipping service
            ("Personalized Internet News Clipping Service"). Distributor will

<PAGE>
 
(herein called "Landlord's Work"). All work to be done by the
Landlord shall be completed in strict accordance with the plans
and specifications and the shop drawings in a good workmanlike
manner and in compliance with federal, state and local law and
shall be certified by the architects for both parties.

     (b) The term "Base Building" shall be deemed to mean the 
building structure, the roof, foundation, footings, all 
parking, landscaping and site work (including site drainage),
plumbing, HVAC and electrical systems as per plans and
specifications annexed hereto as Exibit B. The term "Shell
Building" shall be deemed to mean the slab, roof, complete
weathertight enclosure (glass or plastic), reasonable amount of
temporary power for construction tools and lights and access by
Tenant's contractors. The term "Tenant Work" shall be deemed to
mean all work to be done on the premises by Tenant, at Tenant's
cost and expense, excluding construction of the "Base Building"
which shall be Landlord's Work. The term "substantially 
complete" for the commencement of the lease term only shall be
deemed to mean final construction and installation of all
landlord items required by the Construction Agreement and the
attached Plans and Specifications except for punch list items 
and unfinished landscaping and/or final course on the parking
lot by reason of weather or other seasonal delays.

     (c) The parties shall fully cooperate with each other in
order to meet the construction schedule specified in the
Construction Agreement annexed hereto. Delays in the completion
of Tenant fit-up work caused by the actions or omissions of the
Tenant shall not affect the commencement date, subject however,
to Article 21 hereof. Delays in the delivery of the "Shell
Building" to the Tenant by October 9, 1989 ready for Tenant
Work, shall result in one day deferral of the commencement date
of the term for each one day of delay. Delays to the
construction of the "Base Building" and its delivery to the
Tenant by January 9, 1989 (except for landscaping or the final
course of the parking lot which may be delayed by reason of
weather or seasonal considerations) caused by acts or omissions
of the Landlord shall result in one-day deferral of the
termination date of the term for every one day of delay, and,
in addition, and in either of the aforesaid events, Tenant
shall also receive a rent credit of $1,377.68 for each day of
delay, to be applied to the next successive rent payments due
from Tenant. It is agreed that Landlord's failure to provide
reasonable access, suitable parking, power, light, and storage
and cooperation with Tenant's contractors which result in
delays to the construction schedules, shall be considered
Landlord's delay days. Conversely, if Tenant or Tenant's
contractors fail to cooperate with Landlord's contractor, any
resulting delay shall be considered Tenant delays and shall not
affect the commencement date nor result in any rent credit to
Tenant.


     (d) Subject to the provisions of Article 21, if the
Landlord is prevented from complying with its obligations under
this Article 4 because of delays caused by strikes, riots,
fire, Acts of God, governmental intervention, acts or omissions
of the Tenant, or the like which are not within the reasonable
control of the Landlord (hereinafter referred to in this Lease
as an "excusable delay") the Schedule set forth in the
Construction Agreement annexed as Exhibit A if adversely
affected by an excusable delay, shall be extended by one day
for each day of an excusable delay. Whenever the Landlord is of
the opinion that there has been an excusable delay it shall,
within five (5) days thereafter, notify the Tenant thereof or
be deemed to have waived all claims arising out of a delay in
completing the work in accordance with the provisions of this
Article.

              notwithstanding the foregoing subparagraphs of this Article 4 or
              Article 17 to the contrary, if for any reason other than delays
              which are caused by the Tenant and which adversely affect the said
              Schedule, the Landlord's Work has not been completed, and Landlord
              has not delivered actual possession of the "Base Building" in a
              "substantially complete" condition to the Tenant on or before
              January 23, 1989, the Tenant may, upon Notice delivered to the
              Landlord not later than twenty (20) days thereafter, terminate
              this Lease, or upon Tenant's failure to give such Notice, Tenant's
              right to terminate hereunder shall be deemed waived. In the event
              that the parties are unable to agree on whether the premises is
              substantially complete, then such determination shall be made upon
              the mutual agreement and certifications of the parties'
              architects, however, if the architects are unable to mutually
              agree on and certify "substantial completion", then they shall
              choose a third architect and the decision of a majority of the
              architects as to "substantial completion" shall be binding upon
              the parties.

<PAGE>
 
                object to such Alterations within five (5) days after

                term of this Lease provided that any damage caused by such
                removal shall be repaired by Tenant. In such an event, however,
                Tenant shall not be required to remove pipes, wire and the like
                from walls, ceilings and floors provided that Tenant properly

                and deliver promptly after request of Tenant such instrument or
                instruments embodying the approval of Landlord which may be
                required by any public or quasi-public authority for the purpose
                of obtaining any license or permit for the making of such
                Alterations, Tenant agreeing to pay the cost of any such license
                or permit. Tenant shall not allow any liens to be placed against
                the Premises, or any part thereof, by reason of any such work
                performed by Tenant, and Tenant shall indemnify Landlord 
                therefor in the event of any breach of this covenant.

                Tenant, such removal must be accomplished by the end of the
                Lease term at Tenant's sole cost and expense. In the event the

                machinery, and the like and the removal of any improvements or
                alterations. Tenant's removal of its fixtures, equipment and
                machinery shall not cause any hazardous condition, and upon
                returning possession of the premises to Landlord, the premises 
                shall be free of any hazardous condition.

Inspection         10. Subject to any security and confidentiality policies of
                the Tenant, Landlord and Landlord's agents and representatives
                shall have the right to enter and inspect the Premises at
                mutually agreeable reasonable times during business hours, for
                the purpose of ascertaining the condition of the Premises.
                Subject to such security and confidentiality policies, during
                the period that is six (6) months prior to the end of the term
                hereof, Landlord and Landlord's agents and represenatives shall
                have the right to enter the Premises at mutually agreeable
                reasonable times during business hours for the purpose of
                showing the Premises and shall have the right to erect on the
                Premises a suitable sign indicating the Premises are available.
                The parties hereto mutually agree, at least thirty (30) days
                prior to the normal expiration date hereof, to meet for a joint
                inspection of the Premises. Landlord shall always have the right
                of inspection, as manager, with notification of emergency.

Casualty           11. (a) In the event any portion of the premises is damaged
                by fire or other casualty insured under Article 12(a), and the
                premises can, in the opinion of the Landlord's architect, be
                repaired within one hundred eighty (180) consecutive days from
                the date of damage, the Landlord shall proceed immediately to
                make such repairs as required by paragraph (c). This Lease shall
                not terminate, but the Tenant shall be entitled to a
                proportionate abatement of rent and additional rent payable
                during the period commencing on the date of the damage and
                ending on the date the premises are repaired as aforesaid and
                delivered to the Tenant. For purposes of this paragraph (a) and
                paragraph (c), rental abatement shall be based upon the portions
                of the premises rendered untenantable, unfit or inaccessible for
                use by the Tenant during such period. Notwithstanding the
                foregoing, the Tenant shall provide rent interruption insurance
                for the Landlord's benefit, at Tenant's cost.

                       (b) If (i) in the opinion of the Landlord's architect,
                such damage to the premises cannot be repaired within one
                hundred eighty (180) days from the date of the damage; or (ii)
                the Landlord commences to repair but fails to complete such
                repairs as required by paragraph (c) within the one hundred
                eighty (180) day period, as said period may be extended for an
                excusable delay (as such term is defined in Article 4), either
                party may terminate this Lease by Notice to the other within
                twenty (20) days from the date on which the architect's opinion
                is delivered to the Tenant when termination is based on the
                architect's opinion, and otherwise by such notice within twenty
                (20) days from the end of one hundred eighty (180) day period,
                as it may have been extended by an excusable delay. This Lease
                shall terminate on the thirtieth (30th) day after such notice is
                given, unless the damage repair is completed within ten (10)
                days after giving of such notice or unless such loss or damage
                was caused by Tenant's willful misconduct, or that of its
                employees. If Tenant shall terminate this Lease pursuant to this
                Article 11, then such termination shall be Tenant's sole remedy.

                    (c) In the event neither party exercises its option to
           terminate hereunder the Landlord shall, with due diligence, to
           the extent that the insurance proceeds shall be sufficient for
           the purpose, reconstruct the "Base Building" to substantially  
           the same condition as existed immediately prior to the date of
           damage, and the Tenant shall reconstruct the Tenant Work to
           substantially the same condition as existed immediately prior
           to the date of damage. The Tenant shall be entitled to a
           proportionate abatement of rent and additional rent in the
           manner and to the extent provided in paragraph (a). When
           required by this Article, the architect's opinion shall be
           delivered to Tenant within thirty (30) days from the date of
           damage.

                    (d) Notwithstanding paragraphs (a) and (c) of this Article
           or Article 17 to the contrary, if, by operation of this Article
           the Landlord undertakes but fails to repair and restore the
           premises as required by the provisions of this Article and to
           deliver the repaired and restored areas of the building and
           improvements to the Tenant within two hundred twenty (220)
           consecutive days from the date of the damage, for any reason
           other than a delay caused by an act or omission of the Tenant,
           subject to force majeure or other excusable delay, in which
           event this period may be extended for up to sixty (60)
           additional days, either party may terminate this Lease by
           notice to the other within two hundred thirty (230) consecutive
           days from the date of damage. In the event of termination under
           this Article, this Lease and the term hereof shall terminate on
           the date specified in the notice and rent and additional rent
           shall be apportioned as of the effective date of termination of
           this Lease.

                    (e) In the event that during the last twelve (12) months
           of either the first or second renewal term, a casualty occurs
           which shall require more than 120 days to restore the premises,
           as determined by the Landlord's architect in a similar method
           as under this Article, if the Tenant has not notified the
           Landlord of Tenant's election to renew under the terms of 
           Article 2, the Tenant shall have the right to terminate this lease by
           written notice delivered to Landlord within ten (10) days of Tenant's
           receipt of Landlord's architect's written report, such notice to be
           effective thirty (30) days after Landlord's receipt thereof. Failure
           to deliver such written termination notice shall constitute a waiver
           by Tenant of its right to terminate hereunder. However, if the Tenant
           had notified Landlord of the Tenant's election to renew the term,
           then the provisions set forth in subparagraphs (a) through (d) of
           this Article 11 shall apply to the Tenant's right to terminate this
           lease. Landlord hereby agrees to procure on behalf of Tenant such
           rental insurance policy as to insure the payment of rent during the
           unexpired balance of the term after Tenant has rightfully terminated
           under this subparagraph (e) of Article 11, the cost of which is
           included in the base rent.

Hazard          12. (a)  The Tenant shall, from and after the term commencement
Insurance  date, maintain insurance covering the building including all 
           interior improvements thereto and the parking area, if any, and other
           improvements comprising the premises against loss, damage or
           destruction caused by boiler explosion, fire and the perils specified
           in the standard extended coverage endorsement, and by vandalism and
           malicious mischief. Coverage shall equal at least one hundred (100%)
           percent of replacement costs or actual cash value, exclusive of
           architectural and engineering fees, excavation, footings and
           foundations. The Landlord shall be named as an insured in the
           Tenant's policy. Provided the Tenant has been notified in writing as
           to the names and addresses of the Landlord's mortgagees, such policy
           shall also contain the standard mortgage clause naming the mortgagees
           as their respective interest may appear; however,

                                      -8-
<PAGE>
 
          this requirement shall not restrict or limit the right of the Tenant
          to obtain and hold the insurance proceeds as provided for in Article
          11. Tenant shall use its best efforts to deliver a certificate of such
          policy to Landlord at least thirty (30) days before commencement of
          the Tenant Work and at least thirty (30) days before the expiration of
          any existing policy, but in no event later than ten (10) days prior
          thereto.

                  (b)  The Landlord and the Tenant each hereby waives its right 
          of recovery against the other and each releases the other from any
          claim arising out of loss, damage or destruction to the building and
          improvements on the premises, or contents thereon or therein, to the
          extent its respective property is covered by a policy of insurance
          whether or not such loss, damage or destruction may be attributable to
          the negligence of either party or its respective agent, visitor,
          contractor, servant or employee. Each policy shall include a waiver of
          the insurer's right of subrogation against the party hereto who is not
          an insured under said policy, provided such mutual waiver shall not
          negatively impact the insurance coverage to be provided hereunder.

                  (c)  The Landlord hereby covenants that in the event of any 
          loss, damage or destruction to the premises and the Landlord is
          required by the operation of Article 11 to repair and restore, the
          proceeds which are payable under policies of insurance carried by the
          Tenant shall first be applied to repair and reconstruct the premises
          to the extent required by this Lease and by any mortgage encumbering
          the property.

Condemnation  13. (a)  If the whole or any substantial part of the Premises 
          should be taken for any public or quasi-public use under governmental
          law, ordinance or regulation, or by right of eminent domain, or by
          private purchase in lieu thereof and the taking would prevent or
          materially interfere with the use of the Premises for the purpose for
          which they are being used, this Lease shall terminate and the rent
          shall cease during the unexpired portion of this Lease, effective when
          the physical taking of said Premises shall occur.

                  (b)  If part of the Premises shall be taken for any public or 
          quasi-public use under any governmental law, ordinance or regulation,
          or by right of eminent domain, or by private purchase in lieu thereof,
          and this Lease is not terminated as provided in the subparagraph
          above, this Lease shall not terminate but the rent payable hereunder
          during the unexpired portion of this Lease shall be reduced to such
          extent as may be fair and reasonable under all of the circumstances,
          providing the property remains functionally usable by Tenant.

                  (c)  In the event of any such taking or private purchase in 
          lieu thereof, Landlord and Tenant shall each be entitled to receive
          and retain such separate awards and/or portion of lump sum awards as
          may be allocated to their respective interests in any condemnation
          proceeding.

Taxes         14. (a)  The Tenant shall reimburse the Landlord for all taxes, 
          water and sewer charges, special or other assessments and other
          governmental charges as are finally determined to be legally payable
          by legal proceedings or otherwise (hereinafter called "real estate
          taxes") levied or assessed upon the premises provided the same are due
          and payable during the term and the Landlord has submitted to the
          Tenant the applicable receipted tax bill or copy thereof. In no event
          shall the Tenant be obligated to pay any interest or penalties imposed
          for late payment or otherwise unless the Tenant fails to reimburse the
          Landlord in a timely manner, and in default thereof, Tenant shall be
          liable for interest on any unpaid sum at the prime rate charged by
          Landlord's mortgage lender, plus five (5%) percent. If allowed by law,
          the Landlord shall pay

                                      -9-
<PAGE>
 
                for real estate taxes in installments. Any real estate taxes
                shall be apportioned so that the Tenant shall pay only that
                portion of real estate taxes or installments thereof as falls
                within the term. The Tenant shall not be obligated to pay any,
                income tax, tax on rent or rentals, excess profits or revenue
                tax, excise tax or other similar tax or charge or inheritance,
                franchise, capital levy transfer, estate, succession or other
                similar tax or charge that may be payable by or chargeable to
                the Landlord under the present or future law of the United
                States or the State in which these premises are located or
                imposed by any political or taxing subdivision thereof.

                        (b)  The Tenant shall have the right, by appropriate
                proceedings, to protest or contest any assessment or
                reassessment for real estate taxes, or any special assessment,
                or the validity of either, or of any  change in assessments
                or the tax rate.

                        (c)  In any such contest or proceedings the Tenant may
                act in its own name and/or the name of the Landlord and the
                Landlord will, at the Tenant's request, cooperate with the
                Tenant in any way the Tenant may reasonably request in
                connection with such contest or proceedings. The Landlord shall
                sign such consents or other documents as the Tenant may request.
                Any contest or proceedings conducted by the Tenant shall be at
                the Tenant's expense and, in the event any penalties, interests
                or late charges become payable with respect to the real estate
                taxes as the result of such contest, the Tenant shall be solely
                responsible for any penalties, interest or late charges imposed
                on the Landlord through no fault of the Tenant. Nothing herein
                shall be construed to permit the Tenant to withhold payment of
                taxes during the pendency of any contest or proceeding, unless
                the Landlord shall expressly consent thereto.

                        (d)  The Tenant shall be entitled to receive any tax
                refunds properly allocable to the term of this Lease,as it may
                be extended, and relating to taxes paid by Tenant, as a result
                of any such contests or proceedings.

Signs               15. The Tenant shall have the exclusive right to place its
                signs in, on and about the building and land comprising the
                premises, provided the same are in compliance with law, are
                purchased and installed at the sole cost and expense of the
                Tenant and are removed from the premises at the expiration or
                earlier termination of the term hereof. The Tenant shall be
                responsible for all required applications, fees and permits.
                Notwithstanding the foregoing, the Landlord shall have the right
                to place temporary or construction sign on the premises prior to
                commencement of the Tenant's occupancy.

Compliance          16. (a) During the term the Tenant shall, at its sole cost 
with Law        and expense, promptly comply with all laws, ordinances, orders
                rules, regulations and requirements, including but not limited
                to noise abatement and sound criteria of all federal, state and
                municipal governments and governmental agencies, which are
                applicable to the premises or to the use, manner of use or
                occupancy thereof and maintain the premises in compliance with
                the requirements of the insurance companies from which the
                Tenant purchases the coverages required by this Lease; provided,
                however, that the Landlord shall, at its sole cost and expense,
                comply with all laws, ordinances, orders, rules, regulations and
                requirements and insurance requirements which are applicable to
                those repairs, replacements or alterations or other obligations
                to be performed by the Landlord under the provisions of this
                Lease.

                        (b) After prior notice to the Landlord, the Tenant shall
                have the right to contest by appropriate legal proceedings (in
                the name of the Tenant or the Landlord or both) at the Tenant's

                                     -10-

              sole cost and expenses and with counsel of the Tenant's choosing,
              the validity of any law, ordinance, order, rule, regulation or
              requirement with which, by the provisions of this Lease, it is
              obligated to comply. If by the terms of any such law, ordinance,
              order, rule, regulation or requirement, compliance therewith may
              be legally held in abeyance without incurring any lien or charge
              of record against the premises, and without subjecting the
              Landlord to any fines, penalties or any other liability for
              failure to comply therewith, the Tenant may postpone compliance
              until the final determination of any such proceedings, provided
              that all proceedings shall be prosecuted with due diligence.

Default             17.  (a) The following events shall be deemed to be events 
              of default by Tenant under this Lease:

                         (i) Tenant shall fail to pay any installment of the 
              rent herein reserved when due, or any payment with respect to
              taxes hereunder when due, or any other payment or reimbursement to
              Landlord required herein when due, and such failure shall continue
              for a period of fifteen (15) days following written Notice from
              the Landlord to the Tenant.

                         (ii) Tenant shall become insolvent, or shall make a 
              transfer in fraud of creditors, or shall make an assignment for
              the benefit of creditors.

                         (iii) Tenant shall file a petition under any section or
              chapter of the Bankruptcy Code, as amended, or under any similar
              law or statute of the United States of any State thereof; or
              Tenant shall have filed against it a bankruptcy or insolvency
              proceeding and such proceeding is not discharged within sixty (60)
              days thereafter.

                         (iv) A receiver or trustee shall be appointed for all 
              or substantially all of the assets of Tenant, and such party is
              not discharged within sixty (60) days after appointment.

                         (v) Tenant shall desert the Premises, provided, 
              however, the Premises shall not be deemed deserted so long as
              Tenant pays all charges due hereunder and complies with all of the
              terms hereof, even though it has physically removed itself from
              the Premises.

                         (vi) Tenant shall fail to comply with any term, 
              provision or covenant of this Lease (other than the foregoing in
              this Paragraph 17), and shall not cure or commence to cure such
              failure within thirty (30) days after written notice thereof to
              Tenant, provided that such default shall in all events either be
              cured in full within sixty (60) days of written notice of such
              default except that if such default cannot with due diligence and
              in good faith be cured within such sixty (60) day period, then no
              default shall occur provided Tenant is proceeding with due
              diligence and in good faith to cure such default.

                         (vii) Tenant shall fail to discharge or adequately bond
              any lien placed upon the Premises in violation of Paragraph 26
              hereof within thirty (30) days after such lien or encumbrance is
              filed against the Premises.

              (b) If the Landlord defaults in the performance or observance of
              any provision of this Lease, the Tenant shall give Landlord notice

Option # 2:
- ----------

    Landlord has obtained an option agreement for the purchase of the land 
("Option Parcel 2") on which a 40,000 square foot one (1) floor "flex" building 
may be built in an area where present zoning permits office use. The cost of 
this option, which presently runs until September 1, 1998, is $10,000.00, which 
will be borne by the Tenant. Upon signing this Lease Agreement, the Tenant shall
reimburse the Landlord for this $10,000.00 option payment. A copy of the Option 
Agreement is annexed hereto as Exhibit C. The Landlord also hereby grants the 
Tenant the right, upon written notice to the Landlord, to require the Landlord 
to obtain an extension of this option, on a month to month basis until June 1, 
1990, for a consideration of 1,000.00 per month to be paid by the Tenant.

    Upon written notice by Tenant prior to June 1, 1990, that the Tenant elects 
to have the Landlord construct a flex building an Option Parcel No. 2, the 
Landlord shall use its best efforts to obtain all necessary approvals and to 
close title within six (6) months from the date of Tenant's notice. The Landlord

of closing title to Option Parcel 2, at Landlord's sole expense. However, in the
event that the Landlord is unable to close title and to complete construction of
the building within fifteen (15) months of closing title to Option Parcel 2, 
except for force majeure, then Tenant shall have the option to cancel the lease 
agreement for the premises to be constructed on Option Parcel 2, and all monies 
paid by Tenant to Landlord in connection with this Option # 2 shall be refunded 
by Landlord to Tenant.

Landlord's purchase of Option Parcel No. 2, shall be similar in form and content
to the lease agreement to be entered into hereunder, shall run for a term of at 
least five (5) years, at a rental rate equal to ninety-five (95%) percent of 
fair market rent for a "flex" building similar to the demised premises, as 
determined in the manner under Option # 1, with a five (5) year option to renew.
If the Tenant requires an upgrade above a "flex" building, Tenant shall bear the
additional costs and expenses for such upgrade, to be repaid during the first 
two (2) years of the Lease term in a manner similar to this Lease. If the Tenant
fails or refuses to execute such lease agreement after having elected to have 
Landlord construct the building, then the Tenant agrees to reimburse the

                            CONSTRUCTION AGREEMENT

     Landlord agrees to accept full responsibility for the cost and construction
of the "Base Building", (as defined in the annexed Lease) pursuant to Plans and
Specifications attached hereto as Exhibit B, including all site work, utility
services provided to the premises, primary electric service from NYSEG of 2250
KVA capacity, the "Shell Building" (as defined in the annexed Lease) with a
clear height of 21'-0" inside, HVAC system and roof structure acceptable to
Tenant.

     Landlord agrees to build the "Base Building" in strict accordance with the 
mutually agreed upon Plans and Specifications attached hereto as Exhibit B, as 
the same may be amended or modified upon mutual agreement of the parties 
(provided that the amendments or modifications are within the original scope of 
work) and also in strict accordance with the shop drawings to be hereinafter 
prepared by Landlord's contractors and reviewed by Tenant, and which are to be 
incorporated herein by reference. Landlord shall be solely responsible for 
obtaining all necessary permits and approvals which may be required by any 
governmental authority, the cost of which are to be borne by the Landlord. 
Copies of all permits and approvals are to be furnished to Tenant immediately 
upon receipt by Landlord.

     Both Landlord and Tenant mutually agree upon the following construction 
schedule:

Commencement of Construction
of "Base Building"--                                May 18, 1988

Delivery of "Shell Building" for
commencement of Tenant Work                         October 9, 1988

Substantial completion of "Base Building" --        November 22, 1988

100% completion of "Base Building" and 
commencement of payment of rent --                  January 9, 1989

     Landlord agrees that on October 9, 1988 the "Base Building" shall be at a 
stage of completion such that Tenant Work may commence. Tenant has the exclusive
right to accomplish Tenant fit-up work using its own contractors and/or 
subcontractors. Landlord and Tenant agree that on and after this date, 
contractors and personnel representing both parties will use their best efforts
to cooperate and to work jointly to achieve the above construction schedule, and
to facilitate the completion of Tenant Work by the agreed upon commencement 
date.

     Delays to the completion of Tenant Work caused by the actions or omissions
of the Tenant shall not affect the commencement date, subject however, to the 
force majeure provisions of the Lease Agreement. Delays in delivery of the 
"Shell Building" to Tenant by October 9, 1988 ready for Tenant Work, shall 
result in one day deferral of the commencement date of the term for each one day
of delay. Delays to the construction of the "Base Building" and its delivery to 
Tenant by January 9, 1989 caused by acts or omissions of the Landlord shall 
result in one-day deferral of the termination date of the term for every one day
of delay, and, in addition, and in either of the aforesaid events, Tenant shall 
also receive a rent credit equal to one day's rent for each day of delay.

     It is agreed that Landlord's failure to provide reasonable access, 
reasonable temporary power, storage, parking, and cooperation with Tenant's 
contractors which result in delays to the construction schedules, shall be 
considered Landlord's delay days. Conversely, if Tenant or Tenant's contractors 
fail to cooperate with Landlord's contractor, any resulting delay shall be 
considered Tenant delays and shall not affect the commencement date nor result 
in any rent credit to Tenant.

     It is agreed that delays to final completion of the landscaping and parking
area which are caused by seasonal conditions, and which do not
<PAGE>
 
materially affect Tenant's use of the premises and the parking areas, shall not 
be considered Landlord or Tenant delays. Landlord agrees, however, that the 
parking area, roads and curbing, etc., in their entirety (exclusive of asphalt 
top coat) will be complete upon the commencement date of the term of the Lease, 
and that the asphalt top coat and landscaping will be completed no later than 
May 15, 1989 in such manner so as to minimize interference with Tenant's use of 
the premises.

     Landlord hereby agrees to pay Tenant the following contributions, in cash:

     1.  $195,000, payable sixty (60) days after commencement of work on Tenant 
         improvements upon Landlord's receipt of invoices;
     2.  $25,000 - design fee payable after Landlord's receipt of invoices and 
         Landlord closing on construction financing, such sum to be paid out of
         either of the first two (2) draws on the construction loan.

     Landlord agrees that Tenant will employ Armand P. Avakian and Edward A. 
Sears Associates as project architect and engineers to review and approve the 
design and Plans and Specifications for the base building shell and standard 
mechanical and electrical drawings which will be prepared by Landlord with 
participation and input from Tenant.

     Prior to awarding a construction contract, Landlord shall submit to  
Tenant's architects and engineers, for review and approval, all final 
construction contract documents. Furthermore, Landlord shall submit copies of 
all shop drawings to Tenant's architects and engineers, for review and comments,
prior to the approval of Landlord's architects and engineers. Tenant will review
and comment on shop drawings within nine (9) days or Tenant will have waived its
right to comment on that shop drawing. The results of the review and comments by
Tenant's architects and engineers shall be incorporated on the shop drawings 
prior to approval of the shop drawings by Landlord, and all incorporated 
comments shall be consistent with the agreed scope and quality outlined in the 
Plans and Specifications. Any changes to the Plans, Specifications and/or shop 
drawings shall be approved by the Tenant, in the case of Plans and 
Specifications, or reviewed by Tenant for comments, in the case of shop 
drawings.

     COMPANY OBLIGATIONS (NOTE: MS OBLIGATIONS ARE SET FORTH IN SECTION 3)


COMPANY shall perform the following duties/obligations:
- ------------------------------------------------------

     1.   Offer the ISP Service(s).

     2.   Develop and maintain a Sign-up Server. The Sign-up Server shall be
          operational on a 7X24 basis.

     3.   Establish a toll free telephone number, or any other communication
          medium mutually agreed to by the parties for the processing of orders
          for ISP Subscribers. COMPANY shall notify MS in writing by a mutually
          agreed upon date of such specific communication medium or other
          relevant means of order entry secured by COMPANY for the ISP Service
          and any other COMPANY Information. COMPANY shall use unique numbers,
          extensions or addresses so as to ensure that all ISP Subscribers (e.g.
          those directed to the Sign-up Server by the Referral Server) can be
          easily segregated from other orders received by COMPANY that do not
          originate from the Referral Server for revenue reporting purposes.

     4.   Use and display the "Microsoft Internet Explorer" logo on the home
          page for COMPANY's ISP Service, along with a hot link to
          www.microsoft.com/ie/ie.htm on the face of the home page.
          ---------------------------

     5.   In copies of Microsoft Internet Explorer distributed by COMPANY,
          COMPANY may set the "default" URL to point to COMPANY's home page for
          the ISP Service, provided that such home page includes a hot link to
          www.microsoft.com/ie/ie.htm.
          ---------------------------

     6.   Offer the Microsoft Internet Explorer as the default web browser (i.e.
          the only web browser offered at sign-up) for COMPANY's ISP Service. At
          the time of ISP Service request from an ISP Subscriber, COMPANY shall
          not express or imply that an alternate browser is available. COMPANY
          may provide a non-MS web browser with its ISP Service only upon a
          customer initiated request. COMPANY is not in any way obligated to
          prevent the access to, use or downloading of non-MS web browsers on
          third party services and Internet sites, even if accessible through
          use of the ISP Service. COMPANY may provide links to use and to
          download non-MS web browsers on or for use with the ISP Service solely
          at a single ISP Service location or Internet Site, provided that such
          locations shall be substantially minimized (for example, in a list
          box) and shall not be presented in a manner which would be
          contradictory to the spirit of this Section 6.


     7.   COMPANY shall not advertise or otherwise promote any non-MS web
          browser (e.g. COMPANY shall not display any logo for, or maintain a
          link to, a non-MS web browser) on COMPANY's home page for the ISP
          Service, on the Start Page, or on any COMPANY home page for any other
          internet access service offered by COMPANY.

     8.   At COMPANY'S discretion, use the Microsoft Internet Explorer name and
          logo in COMPANY's packaging, advertising and promotional materials.
          Such use shall be pursuant to MS' standard trademark policies as
          attached hereto and as may be provided by MS to COMPANY from time to
          time.

     9.   n/a

     10.  Before COMPANY is listed in the ISP Phone Book(s), COMPANY will test
          and certify compliance of Access with MS specifications for security
          and authentication protocols, other industry protocols, and other
          specifications and standards specified by MS from time to time in
          accordance with the procedures, and using the testing tools specified
          by MS from time to time, including, without limitation, the
          specifications set forth in

          Exhibit A and the acceptance testing procedures set forth in Exhibit A
          provided that all of the foregoing specifications, protocols,
          standards and procedures are mutually agreed to by COMPANY.

     11.  If MS makes a new release (other than an "Update" release which is
          designated by MS as a change in the hundredths digit [x.x(x)] of any
          component of the Licensed Software available, then COMPANY will
          provide such new release in a timely manner to ISP Subscribers via an
          electronic download.

     "ActiveX" control(s) in the COMPANY'S home page for the ISP Service.
     COMPANY shall notify Microsoft of the ActiveX controls implemented by the
     COMPANY.

 2.  The ISP Referral Fee shall be reduced by an additional [**] if: (a) COMPANY
     uses Microsoft Windows NT and Internet Information Server as the platform
     for COMPANY'S web site that hosts the home page for the ISP Service, or (b)
     COMPANY offers Microsoft Internet Information Server as one of its
     platforms for web hosting services.

 3.  The ISP Referral Fee shall be reduced by an additional [**] if COMPANY uses
     Microsoft FrontPage server extensions on COMPANY'S web hosting service.

 4.  Microsoft shall be paid only once for each new ISP Subscriber regardless of
     the duration of his membership in the ISP Service.

 5.  Microsoft acknowledges that COMPANY may pay fees similar to the
     above-mentioned ISP Referral Fees to QEMs. This Agreement shall not be
     construed as limiting in any way whatsoever COMPANY'S right to make such
     payments, and such payments shall not be construed in any way as abridging
     COMPANY's obligations under this Agreement. COMPANY will not owe Microsoft
     ISP Referral Fees for subscribers to the ISP Service which COMPANY obtains
     other than through the Referral Server.

 6.  Notwithstanding anything to the contrary in this Agreement, provided that
     COMPANY delivers to Microsoft a fully functional "Service Client Software"
     (as defined in the PROMOTION & DISTRIBUTION AGREEMENT dated Sept 18, 1996,
     License number 7699-6269) by January 15, 1997, COMPANY shall have no
     obligation to pay ISP Referral Fees until MS includes COMPANY in the
     "Online Services folder" in the next release of Microsoft Windows
     95 (currently known as "Memphis") and releases such product to
     manufacturing.

                        Microsoft(R) Internet Explorer

                             Click here to start.


1.  Usage

     Use the Internet Explorer online logo (the "Logo") only to promote
     Microsoft Internet Explorer and indicate that your Internet Site includes
     or is compatible with the Microsoft Internet Explorer.

     The Logo may only be used on your Internet Site which must meet the
     applicable Logo Qualification Criteria and may not be used in any other
     fashion.

     Recommended text. Based upon extensive research, we suggest that the
     Internet Explorer Logo be accompanied by the following text: "This site is
     best experienced with ... Click here to start." as indicated in the below
     images. This information clarifies how the logo should be used, especially
     for new Internet visitors who are unfamiliar with the different means of
     navigating the Internet.

     Product name. It should appear as "Microsoft(R) Internet Explorer" at the
     first and most prominent use in all materials and can thereafter be
     referred to as "Internet Explorer."

2. Intent

     You are not permitted to use the logo to disparage Microsoft, its products
     or services, or for promotional goods or for products which, in MS'
     reasonable judgment, may diminish or otherwise damage Microsoft's goodwill
     in the Logo, including but not limited to uses which could be deemed to be
     obscene, pornographic, excessively violent, or otherwise in poor taste or
     unlawful, or which purpose is to encourage unlawful activities. Similarly,

     Internet Explorer," or "Internet Explorer" more prominently than your
     company, product, or Internet Site name.

     Artwork. Use only Microsoft authorized electronic artwork of the Logo. The
     Logo must stand by itself and must include a minimum amount of empty space
     surrounding the Logo (30 pixels) so as to separate it from any other
     object, such as type, photography, borders, edges, and so on. The Logo may
     not be used as a feature or design element of any other Logo.

     Size. The Logo cannot be reduced in size beyond what is electronically
     provided by Microsoft and must be placed in a prominent location on the
     Internet Site where it is used. Do not remove any trademark symbols or
     alter the Logo in any way. Redraws, distortions, or animation of the Logo
     are not permitted beyond what is provided to authorized / registered
     Microsoft Online logo Internet Sites.

     Footnote. Include the following footnote on Internet Sites that include the
     Logo: "Microsoft is a registered trademark in the United States and other
     countries and the Microsoft Internet Explorer Logo is a trademark of
     Microsoft Corporation."

Alterations to these guidelines

Microsoft reserves the right to change the Logo and these Usage Guidelines at
any time and solely at its discretion. If possible, Microsoft will provide
advanced notice of these changes. Any use of the Logo that is not consistent
with these guidelines is strictly prohibited.

Cancellation of authorization to host logo

Microsoft reserves the right to review use of the Internet Explorer Logo.
Disregard for these Usage Guidelines may result in a revocation of the right to
use the logo, and with it all benefits enjoyed through participation in the logo
program.

Third parties improperly using the Logo must correct any deficiencies in their
use of the Logo and/or in the quality of the product used in conjunction with
the Logo upon reasonable notice from Microsoft. Refusal to correct such
deficiencies may result in revocation of the right to use the Logo.

          MICROSOFT(R) INTERNET EXPLORER STANDARD LOGO USAGE GUIDELINES
- --------------------------------------------------------------------------------

                                   Includes

               [LOGO OF MICROSOFT INTERNET EXPLORER APPEARS HERE]

Microsoft has established the following set of guidelines to assist you in
proper use of the Microsoft Internet Explorer standard logo (the "Logo"). 
The power of the Logo lies in its consistent and appropriate use. Any usage
outside these guidelines dilutes the effectiveness of the Logo and makes it more
difficult to defend our rights to the trademark. 
Microsoft reserves the right to change the Logo and/or these Guidelines at any
time at its discretion. Third parties shall comply with the Guidelines as
amended from time to time.

ACCOMPANYING WORDS

The graphic may not be used without the words "Includes," "Microsoft(R)," and
"Internet Explorer" attached, except as otherwise provided below. No additional
or substitute words may be used. The words may not be abbreviated, translated,
or transliterated, as in non-English documentation. Microsoft will, however,
provide the Logo in versions where the word "Includes" may be translated for the
local market, as available. You may not substitute your own translation of the
Logo.

USING THE MICROSOFT INTERNET EXPLORER STANDARD LOGO

 .    Use the Logo only to promote Microsoft Internet Explorer and indicate that 
     your product includes Microsoft Internet Explorer.
 .    This Logo is NOT to be placed on World Wide Web sites for the purpose of
     downloading Microsoft Internet Explorer. For this purpose, please see the
     Microsoft Internet Explorer Online Logo Usage guidelines at
     http://www.microsoft.com/ie/logo/.
 .    Microsoft will provide you with electronic artwork of the Logo. You may not
     alter this artwork in any way.
 .    This Logo is for Microsoft and third party use only as a graphical 
     representation of Microsoft Internet Explorer software.
         .   Microsoft Use: The Logo may be used by Microsoft on packaging, 
             channel, collateral, advertising, direct mail, and events promotion
             materials for Microsoft products that include Microsoft Internet
             Explorer software. When referring to Microsoft Internet Explorer by
             itself, Microsoft may use the Logo without the word "Includes."
         .   Third Party Use: The Logo may be used by third parties authorized
             to distribute the Microsoft Internet Explorer software under a
             separate License and Distribution Agreement. Authorized third
             parties may use the Logo only on the product packaging of products
             that include Microsoft Internet Explorer software and related
             advertising.

LEGAL INFORMATION

 .   The Logo is owned by Microsoft Corporation. All uses of the Logo must 
    include the following notice: "Microsoft is a registered trademark in the 
    United States and other countries and the Microsoft Internet Explorer Logo 
    is a trademark of Microsoft Corporation." A trademark symbol (TM) should 
    appear to the right of the Logo without alteration from the electronic or
    camera-ready artwork provided. In addition, a registered trademark symbol
    ((R)) must appear in the upper-right corner immediately following the word
    "Microsoft." Do not remove any trademark symbols or alter the Logo in
    any way.

                                     -23-
<PAGE>
 
 .     The product name for Microsoft Internet Explorer should appear as 
      "Microsoft(R) Internet Explorer" at the first and most prominent use in 
      all materials and can thereafter be referred to as "Internet Explorer."
 .     Microsoft owns the Microsoft Internet Explorer Logo and all uses of the
      Logo will inure to the benefit of Microsoft. Third parties shall employ
      best efforts to use the Logo in a manner that does not derogate from
      Microsoft's rights in the Logo and will take no action that will interfere
      with or diminish Microsoft's rights in the Logo. Third parties should not
      adopt, use, or register any corporate name, trade name, trademark, service
      mark or certification mark, trade dress, or other designation similar to,
      or containing in whole or in part the Logo.
 .     Third parties may not use the Logo in a manner that would imply that their
      company or any goods or services provided by such third parties are
      sponsored or endorsed by, or affiliated with Microsoft.
 .     Third parties may not display the Logo on packaging, documentation,
      collateral, or advertising in a manner that suggests their product is a
      Microsoft product, or in a manner that suggests Microsoft is a part of
      their product name.
 .     You are not permitted to use the Logo to disparage Microsoft Corporation,
      its subsidiaries, products, or services, or for promotional goods or for
      products which, in Microsoft's reasonable judgment, may diminish or
      otherwise damage Microsoft's goodwill in the Logo, including but not
      limited to uses that could be deemed to be obscene, pornographic,
      excessively violent, or otherwise in poor taste or unlawful, or which
      purpose is to encourage unlawful activities.
 .     Third parties may not imitate Microsoft's product packaging or the Logo in
      any of their materials, including advertising, product packaging, and 
      promotional materials.
 .     The Logo or the names "Microsoft," "Microsoft Internet Explorer," or
      "Internet Explorer" cannot appear larger and/or more prominent than third
      parties' trade name, service name, product name, or trademark on any
      materials produced or distributed by such third parties.
 .     Microsoft reserves the right to object to unfair uses or misuses of its 
      trademarks or other violations of applicable law.

SIZING AND PLACEMENT REQUIREMENTS

 .     Recommended minimum size is 1" high. The "small" graphic interchange 
      format (GIF) file provided is an example of the smallest recommended size.
 .     The Logo with accompanying words must stand alone. A minimum amount of
      empty space must surround the Logo so as to separate it from any other
      object such as type, photography, borders, edges, and so on. The required
      border of empty space around the Logo must be 1/2x wide, where x equals
      the height of the Logo as measured from the top edge of the word
      "Includes" to the bottom edge of the word "Explorer."
 .     You may not combine the Logo with any other object, including, but not
      limited to, other logos, words, graphics, photos, slogans, numbers, design
      features, or symbols.
 .     The Logo may not be used as a design feature on your product, product
      packaging, documentation, collateral, or advertising.

FOUR-COLOR OR ONE-COLOR APPLICATIONS


COLORS

The color version is the preferred way of reproducing the Logo. The Logo
consists of a blue graphic element and black type. The PANTONE(R) Matching
System (PMS) color for the blue is PMS 279 C. Four-color process (CMYK)
equivalents can also be used. For online usage, the blue color should be Red 0,
Green 102, Blue 255 for 8-bit or higher resolution palettes.

The color version can be reproduced only as described here.


BLACK-AND-WHITE APPLICATIONS

The black-and-white Logo consists of a black graphic element and black type.
Please use the file provided.

ACCESSING THE FILES

The print files are provided in Encapsulated PostScript(R) (EPS) and Windows(R)
metafile (WMF) format. Use the EPS files for materials printed to a
PostScript-compatible printer. Use the Windows metafile to print to a
non-PostScript printer.


                                     -24-
<PAGE>
 
These files should not be opened and edited, only placed (for example, select
"import...picture") into software programs such as common page-layout or
presentation programs, word-processing software, and so forth. Due to
translation problems between the Mac and PC, Mac(TM) EPS images may lose their
preview. When you place them into your page-layout document, you will see a box
or big `X' instead of the preview. The image will still print correctly and the
bounding box accurately shows the size of the image. EPS images are sizable, but
please scale proportionately. PC EPS images only have black-and-white previews.
If you chose to use a color PC EPS, it will still preview in black and white.
When you print it, the color will print correctly. EPS format is
device-dependent so the resolution of the device you are printing to is the
resolution you will achieve. The art files include Adobe Illustrator (ART) and
Macromedia Freehand (FH5) format. These are provided for use where the print
files supplied will not work. They are not to be altered.

QUALITY CONTROL

Microsoft reserves the right to review your use of the Logo and to conduct spot
checks on all products, product packaging, marketing materials, and
documentation and may periodically send out requests for samples. Microsoft may
also conduct spot checks in retail outlets and other product sources to monitor
your compliance with these Logo Usage Guidelines. Refusal to submit samples,
noncompliance with these Guidelines, or failure to correct any deficiencies in
your use of the Logo and/or in the quality of the product used in conjunction
with the Logo upon reasonable notice from Microsoft could result in revocation
of your license to use the Logo.

     where otherwise required or permitted under this Section 1.1.8.1, FDRI
     shall employ, in the requisite positions and at the requisite skill levels,
     eleven (11) individuals who will be dedicated by FDRI to the development of
     the MAS System (the "MAS Development Team"). FDRI shall train such persons
     in the skill sets required for their individual MAS Development tasks,
     e.g., CASE tools, database design, realtime on-line processing. If
     ----
     necessary, FDRI may contract with third parties to fulfill the required MAS
     development tasks. In all cases, FDRI will be responsible for the payment
     of the salaries, benefits and project-related expenses for all personnel
     comprising the MAS Development Team.

     FDRI will begin employing personnel for the MAS Development Team

     reasons other than as described below, payment of these expenses shall be
     separately negotiated and agreed upon by the Project Managers and their
     immediate management and approved by CSG's Vice President Client Services
     and PRODIGY's Vice President, Systems Operations and Telecommunications.

     FDRI agrees to bear the full responsibility for hiring and funding any
     additional personnel as may be necessary to achieve the scheduled
     completion date for MAS as reflected in the initial MAS Design Baseline
     approved by the parties. If any changes in the MAS Design Baseline which
     are agreed to by PRODIGY and FDRI pursuant to Section 1.1.3 of this
     Agreement shall result in the need for any additional personnel, then the
     funding for such additional personnel shall be determined by mutual
     agreement of the parties to this Agreement. Notwithstanding the foregoing,
     if any additional personnel are needed due to changes unilaterally required
     by PRODIGY either: (i) to accelerate the completion schedule set forth in
     the MAS Joint Detailed Project Plans, or (ii) to significantly expand the
     project beyond the scope of the MAS Design Baseline agreed to by the
     parties, then PRODIGY shall bear the full cost of all personnel added to
     the project in response to PRODIGY's requirement.

     Confidentiality Agreement, the language contained herein shall prevail.

     (iii) CASE Encyclopedia. The CASE encyclopedia used by FDRI to develop the
     MAS System (the "CASE Encyclopedia") shall be the sole and exclusive
     property of FDRI, and, subject to any rights PRODIGY may have to license
     the CASE Encyclopedia pursuant to this Agreement and any other rights
     PRODIGY has under this subsection, PRODIGY acknowledges and agrees that all
     rights, title and interest in and to the CASE Encyclopedia are and shall
     remain the sole and exclusive property of FDRI.

     FDRI acknowledges and agrees that the CASE Encyclopedia contains data
     and/or information that describes certain PRODIGY Processes as defined in
     subsection 1.1.8.2(b). During the term of this Agreement, prior to: (i)
     using the MAS System (inclusive of the CASE Encyclopedia) to provide data
     processing services to any third party, or (ii) using the CASE Encyclopedia
     to generate software code for computer software programs or systems (other
     than the MAS System) to be used for or by any third party, FDRI will notify
     PRODIGY, in writing, of its intent to so use the CASE Encyclopedia, and
     PRODIGY shall be given a reasonable period of time following

                                       16                           CONFIDENTIAL

     receipt of such notification, not to exceed fifteen (15) days, in which to
     designate to FDRI, in writing, those specific PRODIGY Processes identified
     in the Index referred to in subsection 1.1.8.2(b) (iii) of this Agreement
     which PRODIGY desires to protect from disclosure to, or use by or for, such
     third party. Following such designation, FDRI, at its sole expense, shall
     remove all data and information describing such PRODIGY Processes from the
     CASE Encyclopedia prior to use for or by the third party in question.

     Within thirty (30) days following the effective date of termination of this
     Agreement, or the expiration of the Original Term or the Renewal Period,
     PRODIGY shall designate to FDRI, in writing, those specific PRODIGY
     Processes identified as the Index referred to in subsection l.1.8.2(b)(iii)
     which PRODIGY desires to protect from disclosure to, or use by or for,
     third parties. Following such designation, FDRI, at its sole expense, shall
     remove all data and information describing such PRODIGY Processes from the
     CASE Encyclopedia. Following the removal of all data and information
     describing the PRODIGY Processes designated by PRODIGY, FDRI shall be free
     to use the MAS System and/or the CASE Encyclopedia without further
     restriction.

     (iv) FDRI Processes. FDRI has originally developed certain proprietary
     processes that have been or will be described in the data and information
     which forms a part of the CASE Encyclopedia, but excluding any process: (i)
     mutually recognized by FDRI and PRODIGY under subsection 1.1.8.2(b) as a
     PRODIGY Process; or (ii) generally known to the public prior to any
     disclosure by PRODIGY; or (iii) disclosed to PRODIGY by a third party that
     is rightfully in possession of such information and free of any obligation
     to maintain its confidentiality at the time of disclosure; or (iv)
     generally known to PRODIGY prior to its disclosure by PRODIGY (the "FDRI
     Processes"). All FDRI Processes are subject to the terms of the
     Confidentiality Agreement between the parties dated August 8, 1991. PRODIGY
     acknowledges and agrees that [XXXXX] right, title and interest in and to
     the FDRI Processes, including, without limitation algorithms, methods,
     concepts, designs, know-how, computer programs, subroutines, techniques,
     data or other information of or concerning the FDRI Processes, are and
     shall remain the sole and exclusive property of FDRI. FDRI shall be the
     exclusive owner of all copyrights or patent or trademark rights available
     with respect to the FDRI Processes or any components thereof. PRODIGY shall
     have no proprietary rights in the FDRI Processes other

     than those expressly granted by FDRI in this Agreement, and, except upon
     FDRI's prior written consent, PRODIGY shall not use the FDRI Processes in
     any manner other than as expressly provided in this Agreement. In the event
     of a conflict between this Section 1.1.8.2(a) (iv) and any provision of the
     above-referenced Confidentiality Agreement, the language contained herein
     shall prevail.

     (b) PRODIGY's Ownership Rights.

     (i) The PRODIGY Processes. During the term of this Agreement, PRODIGY has
     and will continue to submit to FDRI certain processes that have been or
     will be described in the data and information which forms a part of the
     CASE Encyclopedia, including but not limited to, processes that are
     generally known to the public. For the purposes of this Agreement, the term
     "PRODIGY Process" shall each process described in the data and information
     contained in the CASE Encyclopedia that has been originally developed by
     PRODIGY, and which, the parties agree: (A) has a specific applicability to
     the conduct of PRODIGY's business that is or will be recognized in the
     design and/or operation of the MAS System, as developed; and (B) is not
     normally or routinely used by other businesses. 


                                       19                           CONFIDENTIAL

     (ii) Designation of the PRODIGY Processes. During the term of this
     Agreement, PRODIGY will notify FDRI, in writing, of its intent to designate
     a particular process as a PRODIGY Process. FDRI shall be given thirty (30)
     days following receipt of such notification to contest the proposed
     designation and to explain why FDRI believes that the process in question
     does not constitute a PRODIGY Process. If FDRI does not respond within the
     required time period, then FDRI shall be deemed to have agreed that the
     process is a PRODIGY Process and the process shall be so identified. If
     FDRI timely responds to PRODIGY's notice, then the designated
     representatives of PRODIGY and FDRI shall negotiate in good faith to
     resolve the issue as soon as practicable. If the parties are unable to
     reconcile their differences within fifteen (15) days following FDRI's
     timely response to PRODIGY, then the matter shall be escalated to the
     respective functional vice presidents of the parties. If these individuals
     are unable to agree on the characterization of the process at issue within
     ten (10) days after the matter has been escalated to them, then the matter
     will be settled by binding arbitration conducted before a single arbitrator
     at a time and place mutually agreed to by the parties. Such arbitrator
     shall be a person who is knowledgeable in the field of computer software


                                       20                           CONFIDENTIAL

                         development and intellectual property rights, and
                         acceptable to both parties. The decision of such
                         arbitrator shall be binding upon the parties. Each
                         party will bear its own costs and expenses, including
                         fees and expenses of counsel, if any, associated with
                         the arbitration.



                         (iii) Index of the PRODIGY Processes. At any time
                         during the term of this Agreement, PRODIGY may choose
                         to remove the PRODIGY Process designation from any
                         process for any reason, either upon FDRI's request or
                         at its own discretion. The parties shall attach as an
                         appendix to this Agreement an Index listing all
                         processes currently designated as PRODIGY Processes,
                         which Index shall be subject to change from time to
                         time to reflect the procedures set forth herein.



                         (iv) Ownership of the PRODIGY Processes. All PRODIGY
                         Processes, and related written documentation, shall be
                         marked as PRODIGY "Confidential" or "Proprietary" and
                         provided to FDRI under the terms of the Confidentiality
                         Agreement between the parties dated August 8, 1991.
                         Subject to the rights of FDRI to describe the PRODIGY
                         Processes in the CASE Encyclopedia and to use the
                         PRODIGY Processes to develop the MAS System, FDRI
                         acknowledges and agrees that all right, title and


                                      21                          CONFIDENTIAL

                         interest in and to the Processes, including, without
                         limitation algorithms, methods, concepts, designs,
                         know-how, techniques, data or other information of or
                         concerning the Processes, are and shall remain the sole
                         and exclusive property of PRODIGY. PRODIGY shall be the
                         exclusive owner of all copyrights or patent or
                         trademark rights available with respect to the PRODIGY
                         Processes or any components thereof. FDRI shall have no
                         proprietary rights in the PRODIGY Processes other than
                         those expressly granted by PRODIGY in this Agreement.
                         In the event of a conflict between this Section
                         1.1.8.2(b) (iv) and any provision of the
                         above-referenced Confidentiality Agreement, the
                         language contained herein shall prevail.


1.3       Travel Expenses. Travel expenses required for either SMS or MAS shall 
          be handled as follows: travel expenses incurred for air fare and
          lodging by FDRI up to $25,000.00 per calendar year shall be at FDRI's
          sole expense. Any travel required by FDRI above $25,000.00 in any
          calendar year shall be billable to PRODIGY. PRODIGY must approve any
          travel in excess of $25,000.00 in any calendar year. FDRI will report
          travel expenses to PRODIGY monthly. The Vice President of Client
          Services, the General Manager of SMS/MAS, the MAS Software Development
          Manager and all FDRI and/or CSG staff sent for non-development
          purposes shall be exempt from above


                                       22                         CONFIDENTIAL

          travel criteria; the travel expenses for these individuals shall be
          the sole responsibility of FDRI.



1.1.10    Termination of Prior Agreement. The Prior Agreement shall terminate as
          of the effective date of this Agreement.



1.2       PROCESSING SERVICES



1.2.1     Description of Processing Services. FDRI shall perform data processing
          and other services for PRODIGY in connection with PRODIGY's member 
          billing operations. The processing services to be made available to
          PRODIGY by FDRI shall include the services for SMS as described in 
          Exhibits 15 and 17, and such services as shall be provided via the MAS
          System as developed by FDRI in accordance with the specifications set 
          forth in Exhibits 20, 21 and 22.



1.2.2     Telecommunications. The processing services to be provided to PRODIGY
          hereunder shall be delivered through a "gateway" connection between
          the FDRI and PRODIGY systems (and the systems of PRODIGY's sub-
          contractors and agents, as appropriate). Accordingly, FDRI shall 
          provide access to PRODIGY, at the FDRI data processing facility, to
          telecommunications lines owned or leased by PRODIGY (at least one
          operating line and one testing line), and, subject


csg.009/121892                         23                         CONFIDENTIAL

          to approval by the FDRI technical staff (which approval shall not be 
          unreasonably withheld, conditioned or delayed), to telecommunications 
          lines owned or leased by PRODIGY's subcontractors or designated 
          agents. Any modem(s) or other specialized telecommunications equipment
          designated by PRODIGY for location at the FDRI data center and 
          dedicated to communications for PRODIGY shall be installed and 
          maintained by FDRI or its designated agents at PRODIGY's expense with 
          the prior written approval by PRODIGY. In all cases, PRODIGY shall
          bear the cost of repairs to its modems and owned or leased
          telecommunications lines, absent damage due to FDRI's negligence or
          willful misconduct.


          All telecommunications equipment referred to above will be configured 
          initially as set forth in Exhibit 8.



1.2.3     Security. FDRI shall maintain the necessary levels of security
          precautions to ensure at least the following, in accordance with 
          Exhibit 14:

                                Physical Site Security

1.2.4     Disaster Recovery. Prior to the end of the first calendar quarter of 
          1993, FDRI shall have in place a new Disaster Recovery Plan that will
          provide a connection at the Business Recovery Center for a tele-
          communications line (owned or leased by PRODIGY or PRODIGY's 
          subcontractor or designated agent) to PRODIGY's network. The new Plan 
          shall provide protection substantially similar to that provided under 
          FDRI's existing Disaster Recovery Plan, described in Exhibit 16.



1.2.5     Maintenance. During any period in which FDRI runs the SMS and/or MAS 
          Systems on its own hardware on behalf of PRODIGY, FDRI shall, at no 
          additional charge, provide maintenance and troubleshooting with regard
          to any defects in the SMS or MAS Systems.



          During any period in which FDRI runs the SMS and/or MAS Systems on its
          own hardware on behalf of PRODIGY -- FDRI shall, at no additional 
          charge, incorporate all SMS and/or MAS System enhancements, 
          maintenance, corrections and production fixes made by FDRI, and shall 
          update and provide to PRODIGY all User Guide and technical 
          documentation on a prompt and regular schedule and in any event not 
          less than semiannually. Hard copy notifications (via bulletins) of the
          changes, as well as on-line help, shall be made available to PRODIGY 
          for use upon implementation of said


                                       25                           CONFIDENTIAL

          changes. In addition, FDRI shall make updated Systems Operations 
          documentation available for PRODIGY's use upon change implementation.


          FDRI will assist in troubleshooting any problems detected either by 
          FDRI or PRODIGY (or PRODIGY's designated subcontractor's or agent's) 
          with the gateway connection to the Systems, and assist PRODIGY in 
          implementing preventative or corrective measures, agreed to in advance
          by PRODIGY, at PRODIGY's expense; provided, however, that the problem 
          is not attributable to the Systems, or to procedural errors caused by
          or under the control of FDRI, or to FDRI's computer or
          telecommunications equipment, in which case the necessary maintenance
          shall be performed at FDRI's expense. If PRODIGY elects to run on
          computers owned or leased by PRODIGY certain MAS such systems
          developed by FDRI, PRODIGY shall be responsible for any additional
          maintenance costs that may arise because such subsystems are no longer
          located on FDRI computers.


1.2.6     Audit Rights. FDRI shall maintain for a period of four (4) years after
          the end of each Processing Year, documentation of sufficient detail to
          enable PRODIGY to verify all charges and all services provided to 
          PRODIGY under the terms of this Agreement during said Processing Year.
          In addition, CSG agrees to maintain for ninety (90) days after the 
          conclusion


                                       26                         CONFIDENTIAL

          of any month evaluated the data used to document the performance 
          standard results specified in Section 3.1.2 below, and to retain
          summary performance standard results for one (1) year after the 
          conclusion of any month evaluated. PRODIGY shall have the right, at 
          PRODIGY's cost and expense, upon sixty (60) days' prior written 
          notice, to use internal or external auditors, during FDRI's normal 
          business hours, to review such data and all operations and records 
          relating to FDRI's performance under this Agreement. FDRI shall 
          cooperate fully with any such audits, which shall not be conducted 
          more frequently than once per year. If such an audit discloses an
          overcharge by FDRI, or failure by FDRI to remit a performance failure 
          credit, of more than $10,000, FDRI shall reimburse PRODIGY for the 
          cost of the audit, and shall be liable to PRODIGY for the overcharges
          and performance failure credit together with interest on such overage

2.1       PROCESSING SERVICES



2.1.1     Prices. The prices for processing services performed under this 
          Agreement are set forth in this Article and Exhibit 17.


                                       27                          CONFIDENTIAL

2.1.2     Price Increases. For each Processing Year after the first Processing
          Year, during the Original Term and any Renewal Period, FDRI shall be
          allowed to increase the prices charged during the immediately
          preceding Processing Year for Ancillary Fees, which, for the purposes
          of this Agreement, shall mean the fees charged for those items listed
          under the heading "Ancillary Fees" in Exhibit 17 Section 3. Such
          Ancillary Fees may be increased annually by an amount equal to the
          rate of change in the CPI for such immediately preceding Processing
          Year; provided that if the rate of change in the CPI is less than two
          percent (2%), FDRI shall be permitted to raise such prices by two
          percent (2%); and further provided that if the rate of change in the
          CPI is greater than seven percent (7%), FDRI shall be permitted to
          raise such prices by seven percent (7%). For the purposes of this
          Section 2.1.2, the percentage change in the CPI during a Processing
          Year shall be calculated by subtracting the CPI for the September
          immediately preceding a Processing Year (the "Base CPI") from the CPI
          for September of the Processing Year, multiplying by 100 and dividing
          the result by the Base CPI.



          For the purpose of this calculation "CPI" shall mean the Consumer
          Price Index for all Urban Consumers as published by the U.S.
          Department of Labor's Bureau of Labor Statistics (1967=100).

                                        28                         CONFIDENTIAL

2.1.3     Postage. FDRI agrees to purchase the postage required to mail account 
          statements, past due notices, letters and other materials mailed by 
          FDRI on behalf of PRODIGY. The amount charged by FDRI while this 
          Agreement is in effect will be (i) the then-current first-class 
          postal rate for each piece of mail not qualifying for the presorted
          rebate or (ii) the regular first class mail charge less a discount of 
          $.042 per piece for each piece qualifying for the presorted discount. 
          If the discount allowed by the U.S. Postal Service for mail qualifying
          for a pre-sorted discount shall change, PRODIGY and FDRI shall 
          negotiate a revised discount taking into account the amount of the
          change and FDRI expenses in obtaining such discount. PRODIGY agrees to
          establish and maintain a deposit with FDRI equal to the monthly 
          estimated expenses for postage. FDRI shall estimate the amount of 
          these fees for each month based upon the projected volume of services 
          involving postage to be performed by FDRI during the following
          processing month. FDRI shall, from time to time, based upon the actual
          postage paid by PRODIGY during the most recent month, request that
          PRODIGY add additional amounts to this deposit if the quantity of
          postage required increases and shall allow PRODIGY to decrease the
          deposit if the quantity of postage required decreases. Upon the
          expiration or termination of this Agreement, this deposit shall be
          returned to PRODIGY; except that any interest


                                        29                        CONFIDENTIAL

          earned on this deposit while it is maintained with FDRI, shall be 
          retained by FDRI.

          FDRI will charge PRODIGY for all pieces of mail sorted and bundled in 
          ZIP Code order, at the rate of $.0046 per piece, with an additional 
          charge of $.0064 per piece for each piece which qualifies for the 
          presorted discount.

2.1.4     Data Exchange. PRODIGY, FDRI and third parties designated by PRODIGY, 
          may exchange information by magnetic tapes/cartridges/disks, tape 
          transmission units in computer-to-computer transmission. PRODIGY shall
          pay all costs of delivery service if magnetic tape/cartridges are
          shipped to FDRI's data center. FDRI may charge PRODIGY for tape
          handling, at the rates shown in Exhibit 17, for magnetic tape/
          cartridges/disks delivered to PRODIGY or third parties designated by 
          PRODIGY.

2.1.5     Courier Expenses. PRODIGY shall pay only for the courier expenses 
          associated with the transportation of special requests of reports and 
          documents from PRODIGY to FDRI and when requested by PRODIGY, from 
          FDRI to PRODIGY. PRODIGY shall retain the right to investigate, and 
          with FDRI implement, automated alternatives for the transfer of 
          special request and standard reports and documents between the 
          parties.

 2.1.6           Change orders. Day-to-day operational changes in the processing
                 services specified in Exhibit 15 and otherwise provided for
                 under this Agreement (e.g., print suppression; operational
                                       ----
                 schedule changes) may only be made with approval of the Project
                 Managers. Substantial changes in the processing services
                 provided under this Agreement (e.g., eliminating the microfiche
                                                ----
                 provided for in Exhibit 17; processing changes requiring
                 coding) may only be made by written amendment hereto.

 2.1.7           Third Party Access. FDRI shall allow third parties access to
                 member, order and account information for the purpose of
                 verifying PRODIGY'S data, as requested by PRODIGY and at
                 PRODIGY's expense, subject to procedures agreed upon between
                 the parties and in accordance with PRODIGY'S Policy on
                 Protecting Member Privacy as set forth in Exhibit 14 Section 5.

 2.2             PAYMENT

                 provided and charges incurred pursuant to this Agreement and
                 for reimbursement of expenses permitted and agreed to by
                 PRODIGY under this Agreement. FDRI shall provide PRODIGY with a
                 single monthly itemized invoice with appropriate documentation
                 and support for all amounts due


                                       31                        CONFIDENTIAL

                 from PRODIGY under this Agreement. Such invoices shall be paid
                 by PRODIGY within thirty (30) days of the invoice's receipt by
                 PRODIGY; provided that all invoices shall be deemed received by
                 PRODIGY on the first business day after Such invoices are
                 delivered by FDRI to a reputable overnight delivery service
                 properly addressed and marked for next-day delivery. If payment
                 has not been received by FDRI within thirty (30) days following
                 PRODIGY's receipt of invoice, then there shall be a late charge
                 equal to twelve percent (12%) per year on the unpaid balance
                 for the period of time from the expiration of such thirty (30)
                 days until payment is received by FDRI.

                 In the event that PRODIGY, in good faith, reasonably disputes
                 any charges on any invoice, the parties shall make reasonable
                 efforts to resolve such disputes. PRODIGY shall not be
                 obligated to remit any late charges for any disputed items;
                 provided, however, that PRODIGY agrees promptly to remit all
                 amounts set forth on the invoices provided by FDRI pursuant to
                 this Section 2.2.1 that are not disputed by PRODIGY. Amounts in
                 reasonable dispute that cannot be resolved in time to avoid a
                 late charge, will be deducted from each invoice and be rebilled
                 by FDRI.

 2.2.2           Termination.

                 the Original Term (as that term is defined in Section 7.1
                 below) upon written notice to FDRI given at any time prior
                 to June 30, 1996.

 2.2.2.2         PRODIGY may terminate this Agreement immediately upon written
                 notice to FDRI in the event that: (i) in accordance with

                 in effect for nine or more consecutive calendar months. If this
                 Agreement is terminated pursuant to this Section 2.2.2.2,

                 to PRODIGY, which notice shall specify the term or terms
                 allegedly breached; provided, however, that if PRODIGY shall
                 cure and remedy such breach within such ninety (90) day period,
                 such notice of termination shall be null and

                 creditors.
 
 2.2.2.5         No termination of this Agreement under Section 2.2.2.3 or
                 2.2.2.4 shall relieve either party from liability for the
                 performance of its obligations arising prior to such
                 termination, nor shall such termination supersede, nullify or
                 otherwise adversely effect any other rights or remedies the
                 terminating party may have available to it at law or in equity.

 2.2.2.6         Except where the context expressly provides to the contrary,

                 (75%) of the Processing Fees paid to FDRI for the processing
                 services provided to PRODIGY under this Agreement during the
                 immediately preceding Processing Year ("Minimum Fees");
                 provided that for Processing Year 1 such minimum amount shall
                 equal at least seventy-five percent (75%) of the Processing
                 Fees paid by PRODIGY under the Prior Agreement for processing
                 services rendered by FDRI during the period from January 1,
                 1991 through December 31, 1991. The term "Processing Fees"
                 shall include only those amounts specifically described as
                 processing fees in Exhibit 17 Section 1. In the event PRODIGY
                 terminates this Agreement up to Section 2.2.2.2, PRODIGY shall
                 not be required to pay Minimum Fees with respect to any
                 Processing Years or portions thereof which remain in the
                 Original Term or, if applicable, the Renewal Period, provided
                 that, if this Agreement is terminated at a time other than the
                 end of a Processing Year, the Minimum Fees for the Processing
                 Year in which termination occurs shall be prorated by
                 multiplying the Minimum Fees otherwise applicable for such
                 Processing Year by a fraction the numerator of which is the
                 number of days between the beginning of the Processing Year and
                 the date of termination and the denominator of which is 365.
                 Any amount of Minimum Fees which remains unpaid for any
                 Processing Year, or portion thereof, shall be paid to FDRI
                 notwithstanding the termination of this Agreement.

3.1.2     SMS and MAS Performance Reporting and Remedies.

               (a) During each calendar month, FDRI agrees to provide PRODIGY 
               with a monthly report listing the performance standards set forth
               in this Article 3 and FDRI's performance during the just
               concluded calendar month relative to those performance standards.
               Within fifteen (15) business days after the end of said calendar
               month, FDRI shall then review this report with PRODIGY. Included
               in each such report shall be an analysis of the data used to
               derive FDRI's performance experience.

               (b) If FDRI fails [**] to perform in accordance with any 3 of the
               performance standards set forth in Section 3.1.1 and not
               identified as "critical," FDRI shall credit PRODIGY with a [**]
               reduction on its bill for processing services during the [**]
               such month. If such failure continues with respect to such
               standards for a [**] such month, FDRI shall credit PRODIGY with
               a [**] reduction on its bill for processing services during such
               [**] month. If such failure continues with respect to such
               standards for a [**] such month, FDRI shall credit PRODIGY with
               a [**] reduction on its bill for processing services


                                          41                        CONFIDENTIAL

               during such [**] month. If such failure continues with respect 
               to such standards for a [**] such month, FDRI shall credit 
               PRODIGY with a [**] reduction on its bill for processing services
               during such [**] month and on the processing services bills for
               any and all consecutive, succeeding months in which such failure
               continues.

               (c) If FDRI fails [**] to perform in accordance with any 3 of the
               performance standards set forth in Section 3.1.1 and identified
               as "Critical", FDRI shall credit PRODIGY with a [**] reduction on
               its bill for processing services during the [**] such month.
               Continuous failure in any and all consecutive, succeeding months
               shall result in a [**] reduction on the applicable bill(s) for
               processing services until the failure is rectified.

               (d) FDRI's failure to meet a performance standard due to any 
               cause beyond its reasonable control and not unique to FDRI such 
               as, but not limited to, the malfunction or failure of any entity 
               from which FDRI must obtain information or have electronic 
               contact in order to perform the services set forth in this
               Agreement shall not be considered to be a


                                       42                         CONFIDENTIAL

               failure for which FDRI shall be responsible under this Agreement.

               (e) PRODIGY agrees that due to the difficulty of determining and
               calculating its damages upon FDRI's failure to perform in
               accordance with the performance standards included in this
               Article 3, the remedies set forth in this Article 3 and Section
               2.2.2.2 of this Agreement shall be PRODIGY's sole and exclusive
               remedies, and PRODIGY hereby elects to waive any and all other
               remedies to which PRODIGY may be entitled under this Agreement,
               for any claim based on FDRI's failure to perform in accordance
               with such performance standards.

3.1.3     Disputes. In the event that the Project Managers and their immediate 
          management cannot resolve disputes within five (5) business days, this
          shall be so documented and escalated to CSG's Vice President Client 
          Services and PRODIGY's Vice President Systems Operations and Telecom-
          munications for resolution by the tenth business day. It shall be the 
          duty of the Project Managers, their immediate management and CSG's 
          Vice President Client Services and PRODIGY's Vice President Systems 
          Operations and Telecommunications to take the necessary action to 
          resolve any such dispute immediately.

               (a) If at the end of the Renewal Period, FDRI and PRODIGY are 
               unable to agree upon a new processing agreement, PRODIGY shall 
               have the option to acquire a license to use the System which FDRI
               is then using to supply PRODIGY services under the terms and 
               conditions of this Agreement for a one time license fee of [**].
               If PRODIGY elects to terminate this Agreement as of the end of
               the Original Term, as provided in Section 2.2.2.1, or to
               terminate this Agreement prior to the end of the Original Term
               pursuant to Section 2.2.2.2, PRODIGY shall have the option to
               acquire a license, as of the effective date of termination, to
               use the System which FDRI is then using to supply PRODIGY
               services under the terms and conditions of this Agreement for a
               one time license fee of [**]. In each case, the license agreement
               shall be in the form of Exhibit 23 to this Agreement and shall
               grant PRODIGY a perpetual, non-exclusive license and right to use
               such System, including the CASE Encyclopedia, at PRODIGY's
               computer facilities to furnish PRODIGY with a data processing

               terminates this Agreement prior to the end of the Original Term 
               pursuant to Section 2.2.2.2, then PRODIGY shall have the option 
               to acquire a license, as of the effective date of expiration or 
               termination as the case may be, to use the System which FDRI is

               license and right to use such System, including the CASE
               Encyclopedia, at PRODIGY's computer facilities to furnish PRODIGY
               with a data processing system for PRODIGY's own operations. In
               addition, by its terms, the license shall prohibit FDRI, for a
               period of five (5) years following the date that such license
               enters into effect, from using such System to provide data
               processing services to any third party that is a direct
               competitor of PRODIGY in any line of business provided on a
               commercial basis by PRODIGY, whether on-line or otherwise,
               domestically or internationally.

               (c) It is understood that PRODIGY shall use any System licensed 
               to PRODIGY pursuant to Section 4.1.3(a) or 4.1.3(b) at its 
               computing facilities only on its owned, leased or operated 
               computers. PRODIGY agrees to hold in confidence the design and 
               documentation of such programs and to use the same only in the 
               conduct of PRODIGY's business. PRODIGY may disclose such programs
               or any documentation related to such programs to an auditor or 
               consultant selected by PRODIGY, provided that FDRI is assured by 
               PRODIGY that such disclosure shall be made pursuant to 
               confidentiality agreements as required by the license agreement
               attached as Exhibit 23. The intent of this Section 4.1.3(c) is to
               allow PRODIGY to perform its own data processing and record
               keeping, on its owned, leased or operated equipment, but not to 
               allow PRODIGY to use the license for the programs developed by 
               FDRI to go into business as a service bureau in direct 
               competition with FDRI in FDRI's business of providing data 
               processing services for subscriber billing or franchise 
               operations.

               (d) In the event PRODIGY exercises any option under Section 
               4.1.3(a) or 4.1.3(b) to acquire a license to use the System which
               FDRI is then using to supply services to PRODIGY under the terms 
               and conditions of this Agreement, FDRI shall grant the license 
               rights


                                        49                        CONFIDENTIAL

               described therein and shall provide full cooperation to assure a 
               smooth transition to PRODIGY's operation of the applicable System
               without interruption to PRODIGY's member billing operations.


5.        LIABILITY


5.1       Liability of FDRI. FDRI shall use due diligence in processing the 
          materials received from PRODIGY, and the performance by FDRI under 
          each provision of this Agreement shall be consistent with current 
          industry standards and established internal quality standards, as 
          applicable to similar functions; provided that in the event that any 
          such industry or internal standard is lower than any analogous 
          performance or internal quality standard set forth in the Exhibits of 
          this Agreement, the latter shall supersede the former as respects 
          FDRI's performance under this Agreement. FDRI shall indemnify PRODIGY
          against any and all liability, loss or damage PRODIGY may suffer as a 
          result of claims, demands, costs or judgments against PRODIGY arising 
          out of FDRI's negligent performance under any provision of this 
          Agreement (except for FDRI's breach of Section 6.1.1); provided, that 
          FDRI's obligation to indemnify PRODIGY as aforesaid shall be limited 
          to:



                                        50                         CONFIDENTIAL

     (a)   The actual cost of reprocessing to correct any such negligent
           performance;

     (b)   The actual net revenue or profit lost by PRODIGY resulting directly
           from the negligent performance; and

     (c)   The additional expenses caused by such negligent performance is
           incurred by PRODIGY in maintaining its operation as nearly normal as
           possible (normal shall mean conditions as they would have existed if
           no negligent performance had occurred).

In no event shall, however, shall FDRI's cumulative liability to PRODIGY during
any one Processing Year under any provision of this Agreement exceed the amount
of the Processing Fees paid by PRODIGY to FDRI pursuant to this Agreement for
processing services provided in the immediately preceding Processing Year;
except that during the first Processing Year, said liability limit shall in no
event exceed the amount of Processing Fees paid for processing services provided
during the period from January 1, 1991 through December 31, 1991, pursuant to
the Prior Agreement. FDRI shall in no event be obligated for any exemplary or
punitive damages.

                                       51                           CONFIDENTIAL

5.2  Liability of PRODIGY. PRODIGY shall indemnify and hold harmless FDRI and
     its employees from and against all claims, damages, losses and expenses
     arising out of FDRI's performance under any provision of this Agreement, to
     the extent that such claim, damage, loss or expense is caused by the
     negligence of PRODIGY, or employees of PRODIGY. PRODIGY shall have no
     obligation to indemnify FDRI against any liability, loss or damage FDRI
     might suffer arising out of FDRI's negligent performance under any
     provision of this Agreement.

5.3  Force Majeure. If the performance of this Agreement or any obligation
     hereunder is prevented, restricted or interfered with by reason of fire or
     other casualty or accident; strikes or labor disputes; war or other
     violence; any law, order, proclamation, regulation, ordinance, demand or
     requirement of any governmental agency; or any other act or condition
     whatsoever beyond the reasonable control of the parties hereto, excluding
     weather conditions other than catastrophic weather conditions, the party
     whose performance is so affected, upon giving prompt notice to the other
     party, shall be excused from such performance to the extent of such
     prevention, restriction or interference; provided, however, that the party
     so affected shall take all reasonable steps to avoid or remove such causes
     of 

                                       52                           CONFIDENTIAL

     shall be specifically developed for the fulfillment of this Agreement and
     shall not infringe upon or violate any United States patent, United States
     copyright, trade secret or other proprietary right of any third party,
     provided that PRODIGY acknowledges that certain licenses, as set forth on
     Exhibit 29, were used by FDRI in the development of the SMS and MAS
     Systems, and such licenses may be required to use the SMS and MAS Systems
     if PRODIGY acquires a license from FDRI pursuant to Section 4.1.1, 4.1.2 or
     4.1.3 of this Agreement. FDRI shall indemnify and hold PRODIGY harmless
     from and against any loss, cost, liability or expense (including reasonable
     attorneys' fees) arising out of any breach or claimed breach of this
     warranty, provided that PRODIGY promptly notifies FDRI of any claim made to
     PRODIGY hereunder and provides FDRI with an opportunity to control the
     defense of the action and all negotiations for settlement or compromise. 

                                       53                           CONFIDENTIAL

     affect the performance of the SMS System, as developed under the Prior
     Agreement. FDRI represents and warrants that those MAS System Enhancements
     developed by FDRI in furtherance of this Agreement shall be free of any
     defects which substantially affect the performance of the SMS System, as
     updated by the SMS System Enhancements.

6.3  Notification. PRODIGY will use reasonable efforts during the period within
     ninety (90) days after the release of the SMS System Enhancements and/or
     Maintenance Changes and/or any subsystem of the MAS System to discover any
     defects. At any time during the period when FDRI is operating the Systems
     on behalf of PRODIGY, or when PRODIGY is operating one or more subsystems
     as provided in Sections 4.1.1 or 4.1.2, PRODIGY shall promptly notify FDRI
     of any defects it discovers and FDRI shall promptly and diligently attempt

1. Introduction


Prodigy Services Corporation (the "Company") is the operator of the Prodigy
Internet service (the "Service"). The Service is an interactive information,
communication and transaction service, used by connecting your receiving and
transmitting equipment (normally a personal computer with a modem connected to
your telephone line) to the Company's network of telecommunications and computer
facilities. In addition to communication, information and transaction services,
the Service provides access to the Internet by means of the software programs
provided by the Company and its suppliers. By completing enrollment and
accepting all of the terms of this Agreement, you become an authorized user (a
"Member") of the Service. Continued acceptance of this Agreement is a condition
of membership. If you do not wish to be bound by this Agreement, please do not
enroll. The Company may change this Agreement at any time, and changes are
effective upon notice to Members. If you do not accept the change, you must
immediately terminate your use of the Service. By continuing to use the Service,
you accept each change. The Company may at any time, without notice or
liability, change, eliminate or restrict the use of, any features or functions
of the Service or limit or change the operation of any feature or function of
the Service.

Any information, products and services available on or through the Internet,
other than information, products and services clearly identified as being
supplied by the Company, are provided by other Internet users or independent
providers ("Third Party Providers"), and each Third Party Provider owns,
maintains and supports its information, products and services. The availability
and contents of an Internet site are the responsibility of the Third Party
Provider of such site. You acknowledge that portions of the Internet may contain
language, pictures or other materials which some individuals may find offensive,
inflammatory, of an adult nature, or otherwise objectionable. Such contents are
the sole responsibility of the applicable Third Party Provider. The Company has
no responsibility for or control over such materials and disclaims any and all
liability for, and knowledge of, their contents. Your access to such materials
is at your own risk. It is your responsibility to use as you see fit Internet
access control software of your choosing to limit access to the Internet by any
minors that you may permit to use your account. Minors who access the Service
are assumed to have parental or guardian consent before accessing the Service.

age (19 or 21 where applicable). You are personally responsible for all use of

your Service account. Using your Service account for illegal, fraudulent or
abusive purposes is grounds for termination of membership, and may be referred
to law enforcement authorities. You are responsible for paying for information,
products and services ordered from the Company or from Third Party Providers
through the Service. The Company is not a party to any transaction between you
and a Third Party Provider, and the purchase, payment, warranty, guarantee,

your Service account, password or any credit or charge card number provided to
the Company at enrollment. Until the Company is notified of a breach of security
(by notice given as described in Section 8), you will remain responsible for any
unauthorized use of your Service account. (Liability for use of credit or charge
cards is subject to your agreement with the card issuer.)

guidelines or practices of the Company in operating the Service, any change in
features or functions, or any change in the amount or type of fees and charges
associated with the Service, is for you to terminate the membership by notice to
the Company. Under our monthly plans, if after the first thirty days of your
membership you voluntarily cancel your account, no refund, including any
membership fees or portions thereof, shall be granted. Charges for premium or
extra fee features, supplemental access charges and phone company charges cannot
be refunded at any time. You will be charged for any extra fee features you
subscribe to or use during that period's billing cycle. If you enroll in a pre-
paid annual membership plan, you may cancel your plan, but you will only be
entitled to a refund as is specified under the terms and conditions of that
plan.

The Company may terminate the membership, or suspend any individual Member's
access to the Service, without notice, for conduct that the Company believes is
a violation of this Agreement or any policies or guidelines posted by the
Company on the Service, or for other conduct that the Company believes harmful
to other Members, to Third Party Providers or to the Service or the business
interests of the Company. If you file a claim against the Company, or a claim
which in any way involves the Company, then the Company may terminate your
membership. Upon termination of your membership by the Company for any reason,
you shall not establish a new membership in any Prodigy service, for five years
from the date of termination. Upon termination of your membership, the Company
shall have no obligation to notify any third parties nor shall the Company be
responsible for any damages that may result or arise out of termination of your
membership. Termination or suspension by the Company of service to a Member also
constitutes termination or suspension (as applicable) of that Member's license
to use the Software.

6. Use of the Service
<PAGE>
 
You acknowledge that the Service is intended for access to and use of electronic
mail, usenet newsgroups, Internet relay chat, the Internet, and any other
proprietary or non-proprietary services that the Company makes available to its
members. You shall not use the Service to operate server programs, including,
but not limited to mail servers, IRC servers, ftp servers, or web servers.

You acknowledge that the use of the Service on a standby or inactive basis is
prohibited. This prohibition includes the use of methods or automated programs
to defeat systems which limit inactivity. The Company may automatically
terminate your session after a certain period of inactivity, which period will
be determined solely by the Company.

You are responsible for providing all equipment, devices and software (other
than the Software) necessary to receive the Service. The Company will provide
telephone numbers to connect to the Service. You are responsible for selecting
the best number for you, and for all telephone fees and charges associated with
the use of the telephone number you select. Use of the Service (or portions
thereof), and of specific telephone numbers, is subject to interruptions at the
Company's discretion or beyond the Company's control. Unauthorized access to the
Service, to restricted portions of the Service, or to the telecommunications or
computer facilities used to deliver the Service, is a breach of this Agreement
and a violation of law.

It is your responsibility to keep your password secret and to change it
frequently. You agree that your Service account will be used by one person at a
time. You may not use another Member's Service account without the specific
consent of that Member. Unauthorized use of another Member's Service account, or
improper solicitation of another Member's password, are grounds for termination
of your membership, and may be a violation of law.

You may not use the Service to submit, copy, upload, post, publish, transmit,
reproduce or distribute information, software, or other material which is
protected by copyright without the specific authority of the copyright owner;
doing so is a breach of this Agreement and may subject you to legal liability.
You are responsible (and could be held liable to others) for all submissions
from your Service account.

Information pertaining to Members of the Service, their e-mail address, and/or
their Service account - which the Company makes available to its Members (for
instance, Member Lists and Community Rosters) - are provided for your personal
use only. You are strictly prohibited from accessing, downloading, printing,
emailing, transferring, posting, selling, sharing, or otherwise using any
Member's information referred to in this paragraph for any non-personal,
commercial, unlawful or illegal purposes.
<PAGE>
 
You are expressly prohibited from sending the same or substantially similar
unsolicited electronic mail message, whether commercial or not, to fifty (50) or
more recipients, and from posting to a newsgroup, bulletin board, or message
board, the same or substantially similar unsolicited note, whether commercial or
not, twenty-five (25) or more times per day through the use of the Service, the
Company's equipment, or in connection with any Company e-mail address, Company
domain name, or any Company trademark including the word "Prodigy." For each day
that this provision is violated, Member shall pay the Company $50.00 per day for
unintentional violations and $500.00 per day for deliberate violations. The
Company may waive all or part of the applicable charges. Neither the Company's
demand, nor payment by the Member of these charges, shall prevent the Company
from terminating the Member's membership, seeking to obtain and enforce other
legal remedies against the Member, including damages or an injunction, or
cooperating with law enforcement agencies in connection with these violations.
The failure to enforce any provision of this Agreement, including this
paragraph, shall not constitute a waiver of any or all of Company's rights,
including the right to receive compensation for such unintentional or deliberate
violations of this Agreement, regardless of when such violations occurred.

7. Information on the Service

THE COMPANY DOES NOT ENDORSE, ASSERT OR STAND BEHIND THE TRUTHFULNESS OR
RELIABILITY OF OPINIONS, ADVICE OR STATEMENTS GIVEN OR MADE BY ANYONE OTHER THAN
AUTHORIZED COMPANY SPOKESPERSONS IN ANY MANNER ON OR THROUGH THE SERVICE,
INCLUDING, WITHOUT LIMITATION, IN PUBLIC POSTINGS AREAS OF THE SERVICE. EXPERTS,
INFORMATION PROVIDERS AND "MEMBER REPRESENTATIVES" ON THE SERVICE ARE NOT
AUTHORIZED COMPANY SPOKESPERSONS.

Opinions, advice and all other information expressed by anyone on the Service,
including information providers under contract with the Company ("Information
Providers") represent their own views and not those of the Company, and should
not be relied on for important personal decisions. For individual situations,
specific professional advice should be sought.

The Company will only use or disclose information specifically about you (or
your Membership) as is permitted by this Agreement, by the Prodigy Internet
Privacy Policy, or by law. Prodigy may make its membership list available to
other organizations so that they may make offers directly to you. If you do not
want your name, address, or other personally identifiable information to be
provided for such purposes, indicate your intent by going to the Mail Controls
Center in the online Member Support Center. From time to time, Prodigy may
record information about your computer, communications equipment and operating
system software (but no other non-Prodigy software). Prodigy, or other
organizations carefully selected by Prodigy, will use this information on an
individually-identifiable basis only to (i) analyze how current or future
Service features may operate on your equipment; (ii) monitor or improve the
performance of the Prodigy software on your equipment; or (iii) tell you about
enhancements and offerings that may become available to
<PAGE>
 
you. Prodigy may use or disclose aggregated (not personally identifiable)
information regarding Members for any purpose.

The Service lets you share information with other Members as well as with users
of the Internet who are not Members. You agree not to use the Service to send,
store, or submit for public posting any obscene, sexually explicit, or illegal
material (including material the transmission of which violates any applicable
law) or material which violates Internet standards or customs. The Company
reserves the right (but is not obligated) to review and remove any material
submitted for display or placed on the Internet, excluding private email. The
Company may remove from the Internet any material that the Company believes
violates this Agreement, any policies or guidelines posted by the Company on the
Service or any Internet standards or customs, or is harmful to other Members, to
Third Party Providers, or to the Service or the business interests of the
Company. You are responsible for material sent through or displayed on the
Service under your Service account, even if a claim should arise after
termination of your membership.

The Company will comply in all respects with the Electronic Communications
Privacy Act of 1986, as amended, ("ECPA") relating to private e-mail sent or
received through the Service, as well as other personal information members have
provided. The Company will not inspect the contents of private e-mail, or
disclose their contents to anyone other than the writer or an intended
recipient, without the consent of either the writer or an intended recipient,
except as permitted or required by law. The Company may establish time limits
and/or other criteria under which private e-mail will be automatically removed
from your online mailbox. The Company will have no responsibility for retaining
or delivering private e-mail that are located in a Member's online mailbox at
the time of that Member's suspension or termination, or that are addressed to
such Member thereafter. Subject to the subpoena, warrant and court order
provisions of ECPA, the Company must provide member information to the proper
authorities.

A "public postings area" of the Service is any area where Members may submit
material ("Submissions") for viewing by other Members or by non-Members using
Internet facilities, and view Submissions by other Members or by non-Members
using Internet facilities, including but not limited to, bulletin boards or chat
rooms, and similar Internet facilities, even if such area is not available to
all Members. You agree to use public postings areas only in accordance with this
Agreement, any policies and/or guidelines for the area that are displayed on the
Service and Internet standards or customs.

You may not submit copyrighted material to public postings areas without the
specific authority of the copyright owner; doing so is a breach of this
Agreement and may subject you to legal liability. BY SUBMITTING MATERIAL TO A
PUBLIC POSTINGS AREA, YOU AGREE TO INDEMNIFY THE COMPANY, AND ITS INFORMATION
PROVIDERS, THEIR EMPLOYEES AND CONTRACTORS, AND HOLD THEM HARMLESS FROM ALL
CLAIMS, INCLUDING CLAIMS FOR LIBEL AND SLANDER, ARISING FROM THE SUBMISSION.
Remember: You are responsible (and could be held liable to others) for all
<PAGE>
 
submissions from your Service account. Neither the Company nor its Information
Providers shall be responsible or have any liability for material displayed in a
public postings area unless posted by its authorized spokesperson. Experts,
Information Providers and "Member Representatives" are not authorized Company
spokespersons.

By submitting material to a public postings area you are irrevocably granting
the Company permission to do anything the Company may choose with all parts of
the Submission, as if it were in the public domain, including modifying it or
using it commercially and authorizing others to do so. You are also irrevocably
granting everyone else (including non-Members) permission to reproduce and/or
redistribute all or parts of your Submission in any form for non-commercial
purposes. In addition, anyone is free to use information contained in a
Submission for any purpose, at their own risk.

The Company may establish time limits and/or other criteria under which
Submissions will be automatically removed from public display. The Company has
the right, but is not obligated, to maintain archives of Submissions, regardless
of whether they were actually posted on the Service, and the Company may use or
disclose archived Submissions in any manner it deems appropriate.

8. Notices

The Company may give notices to Members by electronic mail through the Service,
by a general posting on the Service, or by conventional mail. Notices by Members
to the Company must be given by calling telephone number 1-800-213-0992 or
sending electronic mail to:
[email protected]. A notice by a Member to the Company will not change the
terms of this Agreement, or the terms of any Company policy or guideline, unless
the change is expressly accepted in writing by an authorized officer of the
Company. Customer Care representatives (including supervisors) are not
authorized to accept such changes.

1. Introduction

Prodigy Services Company ("Prodigy") is the operator of the Prodigy service (the
"Service"). The Service is an interactive information, communication and
transaction service, used by connecting your receiving and transmitting
equipment (normally a personal computer with a modem connected to your telephone
line) to Prodigy's network of telecommunications and computer facilities.

By completing enrollment and accepting all of the terms of this Agreement, you
become an authorized user of the Service (a "Member"). Continued acceptance of
this Agreement is a condition of Membership. If you do not wish to be bound by
this Agreement, please do not enroll. Prodigy may change this Agreement at any
time. Changes are effective upon notice to Members (see Section 8 regarding
Notices). To read the current Agreement on the Service at any time, GoTo/Jump:
member agreement.

Each Service Membership can include up to six separate Members. The Member whose
Service ID ends in "A" is the Membership Holder, and may authorize up to five
other people to be Members under the Membership Holder's account.

The Membership Holder has special responsibilities in addition to the
responsibilities of being a Member. Both types of responsibilities are described
in Sections 2 and 3. Members must be individuals, and not (except with Prodigy's
written consent) firms, businesses or institutions.

Prodigy may at any time, without notice or liability, change or eliminate any
Service content or features, restrict the use of any portion of the Service,
including limiting the time of its availability, the amount of use permitted, or
the Members who are permitted to use it), or limit or change the operation of
any feature of the Service. Any changes, restrictions, or limitations may be
applied to all or to individual Members in a Membership, and may be applied
<PAGE>
 
regardless of whether a multiple month Membership has been purchased or any
payments have been pre-paid.

Each Membership includes periodic issues of various Member newsletters or other
communications.

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

2. Membership Responsibilities; Prodigy Software License

Responsibilities of All Members. You are responsible for complying with all
terms and conditions of this Agreement, and, with all policies and guidelines
posted on the Service. You are personally responsible for all use of the Service
under your ID (including payment for orders placed) even if you allow someone
else to use your ID. Using your ID for illegal, fraudulent or abusive purposes
is grounds for termination of Membership, and may be referred to law enforcement
authorities. Enrolling or using any ID on the Service under a name other than
your own is prohibited, except where the Service permits "nicknames" or other
identifiers.

You must keep all Membership-related information that you store on the Service
up to date, including your address, any credit, debit or charge card numbers and
expiration dates, and any Service payment information.

You must promptly inform Prodigy if you suspect any breach of security, such as
loss, theft, or unauthorized disclosure or use of your ID, password or any
credit, debit or charge card number stored on the Service. Until Prodigy is
notified of a breach of security (by notice given as described in Section 8, or
by telephone at 1-800-PRODIGY (1-800-776-3449)) you will remain responsible for
any unauthorized use of the Service occurring under your ID. (Liability for use
of credit, debit or charge cards is subject to your agreement with the card
issuer.)

You may use the ordering functions of the Service only to place valid orders for
merchandise, services or other items for which such ordering functions are
intended.

The Service is provided for your personal use only. Unless you have Prodigy's
express written consent, you may not resell it, in whole or part, or
<PAGE>
 
otherwise commercially exploit it, or assign or transfer your Membership to
anyone else.

Responsibility of Membership Holders. You have overall responsibility for your
Membership, which includes the proper use of the Service by all Members of your
Membership. You are also responsible for all fees and charges incurred by the
Membership (see Section 3), and for payment for all orders placed by any minor
Member in your Membership. The Membership Holder must be an adult and an
individual to use the Service. By accepting this Agreement, the Membership
Holder confirms that he/she is an adult of at least 18 years of age (19 where
applicable).

Prodigy may terminate, without notice, any Membership where the Membership
Holder is a minor, or, in Prodigy's sole discretion, may permit an adult to
become the Membership Holder under procedures established by Prodigy. Access to
certain portions of Service content by other Members of the Membership may be
controlled by and is the responsibility of the Membership Holder.

Prodigy Software License. All Prodigy software provided to you, and each revised
version thereof, is licensed to you by Prodigy only for use in connecting to and
using the Service from within the 50 United States, the District of Columbia,
Puerto Rico, and Canada and you may use copy it only as instructed by Prodigy.
Use or copying for any other purpose is prohibited and is a breach of this
Agreement. The Prodigy software files remain Prodigy's property at all times,
and Prodigy may make changes to the number and/or content of these files
directly while you are connected to the Service. (The Prodigy software does not
affect or involve any other files in your computer without your authorization.)
You accept the terms of this license by using the Prodigy software. This license
will terminate upon termination of the Membership for which it was issued. At
that time, the Membership Holder must return the Prodigy software to Prodigy or
destroy it.

Prodigy is not responsible in any way for any non-Prodigy computer programs or
devices intended for use in connection with the Service and/or the Prodigy
software even if such programs or devices are advertised and/or made available
on the Service.

- ----------------------------------
<PAGE>
 
3. Fees and Payment

The Membership Holder is responsible for paying all fees and charges (plus
applicable taxes) associated with use of the Service under all of the IDs of the
Membership, including those incurred for extra fee features or options. Prodigy
reserves the right to change the amount of, or basis for determining, any fee or
charge, and to institute new fees or charges, and will give the Membership
Holder at least 30 days prior notice (as provided in Section 8) of any increase
in any existing fee or charge for Service access or use.

All fees or charges that are additional to the monthly Service fee (including
fees or charges for using certain features, functions or modem speeds, or for
using certain features above usage levels established from time to time by
Prodigy) apply, and may be imposed or changed, regardless of whether a multiple
month Membership has been purchased or an advance payment of the monthly Service
fee has been made.

All fees and charges are payable in accordance with billing terms in effect at
the time the fee or charge becomes payable. Prodigy may require payment of any
or all fees and charges to be made by a valid, approved major credit, debit or
charge card. Current fees and charges are posted on the Service. Unless
otherwise stated, all amounts are in U.S. Dollars. GoTo/Jump: fees to view
current fees.

By authorizing Prodigy to charge a credit, debit or charge card for service fees
and charges, you are authorizing Prodigy to automatically continue charging that
card during your Membership.

Upon request to Prodigy, Membership Holders may receive information that
supports charges for use of the Service by themselves or their authorized
Members. For online statement information, GoTo/Jump: statement.

Ordering Merchandise, Services and Information. You may order, and are
responsible for paying for, many types of merchandise, services and information
from merchants and advertisers ("Merchants") through the Service. Merchants are
independently owned and operated businesses. Prodigy is not a party to any
transactions with Merchants, and the purchase, payment, warranty, guarantee,
delivery, maintenance and all other matters
<PAGE>
 
concerning merchandise, services or information ordered from Merchants are
solely between you and the Merchant. All orders are subject to acceptance by the
Merchant. (See Section 7 regarding information about Members provided to
Merchants with orders.)

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

4. Termination of Membership

Either the Membership Holder or Prodigy may terminate the Membership at any time
and without cause. The only right with respect to dissatisfaction with any
policies, guidelines or practices of Prodigy in operating the Service, any
change in Service content, or any change in the amount or type of fees and
charges associated with the Service, is for the Membership Holder to terminate
the Membership by notice to Prodigy. See Section 8 regarding notices.

Prodigy may terminate the Membership, or suspend any individual Member's access
to all or any part of the Service, without notice, for conduct that Prodigy
believes is a violation of this Agreement or any policies or guidelines posted
by Prodigy on the Service, or for other conduct that Prodigy believes harmful to
other Members, to Merchants or Information Providers, or to the Service or the
business interests of Prodigy.

If you file a claim against Prodigy, or a claim which in any way involves
Prodigy, then Prodigy may terminate your membership. Upon termination of your
membership by Prodigy for any reason, you shall not establish a new membership
in any Prodigy service, for five years from the date of termination.

Upon termination of a Membership by Prodigy, Prodigy will refund any unused
portion of prepaid fees or charges (excluding fees and charges for extra fee
features that are stated to be non-refundable at the time they are accepted),
after satisfying any outstanding balances owed Prodigy. Upon voluntary
termination of Membership by the Membership Holder, no refund, including any
membership fees or portions thereof, shall be granted. Membership Holder will be
charged for any extra fee features subscribed to or used for that period's
billing cycle.
<PAGE>
 
Termination of service to the Membership Holder automatically terminates service
to all other Members in the Membership. Upon termination or suspension of
service to a Member, that Member's banking, brokerage and other third-party
relationships will no longer be accessible through the Service.

Prodigy shall have no obligation to notify any third parties nor shall Prodigy
be responsible for any damages that my result or arise out of termination of
your membership.

Termination or suspension by Prodigy of service to a Member also constitutes
termination or suspension (as applicable) of that Member's license to use the
Prodigy software.

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

5. Use of the Service

You are responsible for providing all equipment, devices and software (other
than the Prodigy software) necessary to receive the Service. Prodigy will
provide telephone numbers to connect to the Service, which for most Members will
include a local number. You are responsible for selecting the best number for
you, and for all telephone fees and charges associated with the use of the
telephone number you select. If you have any question about which telephone
number is best for you, check with your local phone company.

The Service will be available during the hours stated on the Service. GoTo:
service hours.

Use of the Service (or portions thereof), and of specific telephone numbers, is
subject to interruptions at Prodigy's discretion or beyond Prodigy's control.
Unauthorized access to the Service, to restricted portions of the Service, or to
the telecommunications or computer facilities used to deliver the Service, is a
breach of this Agreement and a violation of law.

You acknowledge that the Service is intended for use of electronic mail, usenet
newsgroups, chat, file transfers via ftp, interactive games, browsing of the
World Wide Web, and any other proprietary or non-proprietary services that the
Company makes available to its members. You shall not use the
<PAGE>
 
Service to operate server programs, including, but not Limited to mail servers,
IRC servers, ftp servers, or web servers.

You acknowledge that use of the Service on ,a standby or inactive basis is
prohibited. This prohibition includes the use of methods or automated programs
to defeat systems which limit inactivity. Prodigy may automatically terminate
your session after a certain period of inactivity, which period will be
determined solely by Prodigy.

Membership Holders may suspend Service use by other Members in the Membership
through the means provided on the Service. GoTo: member access. Prodigy gives
the Membership Holder the ability to limit access of Members in the Membership
to certain content available on or through the Service, including access to
content on the Internet over which Prodigy exercises no control. The
responsibility for controlling Member access to and use of such content areas is
solely that of the Membership Holder.

Information pertaining to Members of the Service, their email address, and/or
their Service account - which Prodigy makes available to its Members (for
instance, Member Lists and Community Rosters) - are provided for your personal
use only. You are strictly prohibited from accessing, downloading, printing,
emailing, transferring, posting, selling, sharing, or otherwise using any
Member's information referred to in this paragraph for any non-personal,
commercial, unlawful or illegal purposes.

Unsolicited Commercial Emails

You acknowledge that you are expressly prohibited from utilizing the Service,
Prodigy's equipment, any Prodigy email address or using the word "Prodigy" in
connection with the sending of the same or substantially similar unsolicited
electronic mail messages, whether commercial or not, to fifty (50) or more
recipients. For each day that this provision is violated, Member shall pay
Prodigy $50.00 per day for unintentional violations and $500.00 per day for
deliberate violations. Prodigy, at its sole discretion, shall determine whether
such violations are unintentional or deliberate. Prodigy may waive all or part
of the applicable charges. Neither Prodigy's demand, nor payment by the member
of these charges shall prevent Prodigy from seeking to obtain other legal
remedies against the member, including termination of membership, damages or an
injunction. The failure to enforce any provision of this Agreement, including
this paragraph, shall not constitute a waiver of
<PAGE>
 
any or all of Prodigy's rights, including the right to receive compensation for
such unintentional or deliberate violations of this Agreement, regardless of
when such violations occurred.

IDs and Passwords.

Use of the Service requires both an ID and a password. Each new Member receives
a unique ID and a temporary password, and must choose a new password upon
enrollment. Your ID is your address on the Service, and you and Prodigy may
disclose it to others.

The Service may also permit Members to select an additional identifier, called a
"NetName," for use with electronic mail and other features as Prodigy may
determine, and you and Prodigy may disclose NetNames to others as well.

Your password is the key that unlocks access to your personal information on the
Service. Anyone knowing both your ID and password can gain access to your
personal information and misuse it, so KEEP YOUR PASSWORD SECRET; use a password
that is hard to guess (for example, do not use your first or last name); and
change your password frequently. REMEMBER YOUR PASSWORD! If you forget your
password, Prodigy may disclose it to you under security procedures determined by
Prodigy, but reserves the right to charge for doing so. For more information on
passwords, GoTo/Jump: password security. To change your password, GoTo/Jump:
change password.

You may not use another Member's ID without the specific consent of that
Member. Unauthorized use of another Member's ID, or improper solicitation
of another Member's password, are grounds for termination of your
Membership, and may be a violation of law.

For your convenience, Prodigy provides an option that allows you to connect to
the Service automatically, without manually entering your ID and password each
time. Software available from third parties may also offer this function. If you
choose to use any automatic connection function, you acknowledge that anyone who
has access to your computer can also gain access to and abuse your Service
